具体实施方式detailed description
下面详细描述本申请的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,旨在用于解释本申请,而不能理解为对本申请的限制。Hereinafter, embodiments of the present application will be described in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.
下面参考附图描述本申请实施例烹饪器具以及烹饪器具的烹饪控制方法。The following describes the cooking appliance and the cooking control method of the cooking appliance according to the embodiments of the present application with reference to the drawings.
首先,需说明的是,根据大米的糊化特性,在蒸煮到米的糊化温度例如62℃以上时淀粉颗粒便开始溶出糊化,并产生黏性,随着烹饪器具的锅底温度的急剧升高,米粒很快黏结成团块并阻碍热量和高温气泡流的均衡分布,造成米饭受热不均匀。而受热不均匀将导致米饭局部糊化不足或局部糊化过度等问题,米饭口感差,香气不足。因此,在煮饭过程中,需要尽量避免受热不均匀的情况出现。First of all, according to the gelatinization characteristics of rice, starch granules begin to dissolve and gelatinize when the gelatinization temperature of the rice is cooked above 62 ° C, for example, and become sticky. When it rises, the rice grains quickly clump into clumps and hinder the balanced distribution of heat and high-temperature bubble flow, resulting in uneven heating of the rice. The uneven heating will lead to problems such as insufficient local gelatinization or excessive local gelatinization, poor taste of the rice and insufficient aroma. Therefore, during the cooking process, it is necessary to avoid uneven heating as much as possible.
本申请发明人通过对煮饭过程进行分析发现,在米粒未开始糊化或刚开始糊化时,利用沸腾所产生的脱离气泡对米粒形成扰动,米粒在扰动情况下相互间互不粘连,可以避免结块。同时,沸腾气泡形成密集的气泡通道向上输送热量和水份,使米粒更均匀的受热和吸水。The inventor of the present application analyzed the cooking process and found that when the rice grains did not start to gelatinize or just began to gelatinize, the detached air bubbles generated by boiling formed disturbances on the rice grains, and the rice grains did not stick to each other under the disturbance condition. Avoid agglomeration. At the same time, boiling bubbles form dense bubble channels that transport heat and water upwards, making the rice grains more uniformly heated and absorbed.
应理解,根据物理常识,沸点即液体的饱和蒸汽压等于外界压强的温度,当液体沸腾时,在其内部所形成的气泡中的饱和蒸汽压与外界施予的压强相等即:Pv=Pe+2σ/R,Pv为气泡内饱和压力,Pe为液体外部气压,σ为气泡表面张力,R为气泡半径。因此,大气压越高沸点越高,大气压越低沸点越低。由此,通过将烹饪器具的烹饪腔内的压力降低,可以使沸腾温度降至米饭未开始糊化或刚开始糊化的温度附近。It should be understood that according to physical common sense, the boiling point, that is, the temperature of the liquid's saturated vapor pressure, is equal to the temperature of the external pressure. When the liquid is boiled, the saturated vapor pressure in the bubbles formed inside it is equal to the pressure given by the outside world: Pv = Pe + 2σ / R, Pv is the saturation pressure inside the bubble, Pe is the external pressure of the liquid, σ is the surface tension of the bubble, and R is the radius of the bubble. Therefore, the higher the atmospheric pressure, the higher the boiling point, and the lower the atmospheric pressure, the lower the boiling point. Accordingly, by reducing the pressure in the cooking cavity of the cooking appliance, the boiling temperature can be reduced to a temperature near the temperature at which the rice does not start to gelatinize or to begin to gelatinize.
本申请实施例通过在加热过程中抽取烹饪腔内空气,使烹饪腔内形成负压,米水在较低温度(米粒糊化但未粘结成团前的温度)产生沸腾气泡,从而,气泡扰动使米粒松散不黏结,确保米饭的受热均匀性。In the embodiment of the present application, the air in the cooking cavity is extracted during the heating process, so that a negative pressure is formed in the cooking cavity. The rice water generates boiling bubbles at a relatively low temperature (the temperature before the rice grains are gelled but not bound into a ball). The disturbance makes the rice grains loose and non-sticky, ensuring the uniformity of heating of the rice.
下文结合具体的例子,详细描述本申请一种实施例的烹饪器具以及烹饪器具的烹饪控制方法。The following describes in detail a cooking appliance and a cooking control method of the cooking appliance according to an embodiment of the present application with specific examples.
根据图1-2的实施例,本申请实施例的烹饪器具100包括锅体10、盖体20、真空装置30和加热装置40。这里的烹饪器具100可以是电饭煲等。According to the embodiment of FIGS. 1-2, the cooking appliance 100 in the embodiment of the present application includes a pot body 10, a cover body 20, a vacuum device 30, and a heating device 40. The cooking appliance 100 here may be a rice cooker or the like.
其中,锅体10限定出上表面敞开的烹饪腔11,即锅体10具有顶部敞开的烹饪腔11。盖体20可枢转地连接在锅体10上,并在关闭位置和打开位置之间活动以关闭或打开烹饪腔11,即盖体20可活动地安装于锅体10。并且,在盖体20处于关闭位置时锅体10和盖体20之间形成密封的烹饪腔11。真空装置30用于在烹饪腔11密闭时对烹饪腔11进行抽真空以使烹饪腔11内形成负压。The pot body 10 defines a cooking cavity 11 with an open upper surface, that is, the pot body 10 has a cooking cavity 11 with an open top. The cover body 20 is pivotably connected to the pot body 10 and moves between a closed position and an open position to close or open the cooking cavity 11, that is, the cover body 20 is movably mounted on the pot body 10. Moreover, when the lid body 20 is in the closed position, a sealed cooking cavity 11 is formed between the pot body 10 and the lid body 20. The vacuum device 30 is configured to evacuate the cooking cavity 11 when the cooking cavity 11 is closed, so that a negative pressure is formed in the cooking cavity 11.
具体地,真空装置30可设在盖体20内。盖体20上设有抽气口21、排气口22和进气口23,抽气口21与进气口23分别连通烹饪腔11,排气口22连通抽气口21。其中,需要抽气时,真空装置30连通抽气口21与排气口22,真空装置30从抽气口21抽取烹饪腔11中的气体,并通过排气口22排出烹饪腔11外。Specifically, the vacuum device 30 may be provided in the cover body 20. The cover 20 is provided with an air inlet 21, an air outlet 22, and an air inlet 23. The air outlet 21 and the air inlet 23 are respectively connected to the cooking cavity 11, and the air outlet 22 is connected to the air outlet 21. Wherein, when air extraction is required, the vacuum device 30 communicates with the air outlet 21 and the air outlet 22, and the vacuum device 30 extracts the gas in the cooking cavity 11 from the air outlet 21 and discharges the air out of the cooking cavity 11 through the air outlet 22.
如图2所示,根据本申请的一个实施例,真空装置30可包括:真空泵31和连接管32。真空泵31设在盖体20内,真空泵31通过连接管32分别连通抽气口21和排气口22。真空泵31工作时,烹饪腔11内的气体在真空泵31的抽吸作用下,通过连接管32排出烹饪腔11外,从而使烹饪腔11内形成负压,即言,真空装置30用于在烹饪腔11密闭时对烹饪腔11进行抽真空以使烹饪腔11内形成负压。As shown in FIG. 2, according to an embodiment of the present application, the vacuum device 30 may include a vacuum pump 31 and a connection pipe 32. A vacuum pump 31 is provided in the cover body 20, and the vacuum pump 31 communicates with the suction port 21 and the exhaust port 22 through a connecting pipe 32. When the vacuum pump 31 is operating, the gas in the cooking chamber 11 is exhausted from the cooking chamber 11 through the connection pipe 32 under the suction of the vacuum pump 31, so that a negative pressure is formed in the cooking chamber 11, that is, the vacuum device 30 is used for cooking When the cavity 11 is closed, the cooking cavity 11 is evacuated to form a negative pressure in the cooking cavity 11.
其中,利用真空泵31调节烹饪腔11的负压情况,可控制性较强,而且利用连接管32连通真空泵31与抽气口21和排气口22,有利于提升真空装置30的密闭性,避免因气体泄漏影响烹饪腔11内的负压。Among them, the use of the vacuum pump 31 to adjust the negative pressure of the cooking chamber 11 has strong controllability, and the connection of the vacuum pump 31 with the suction port 21 and the exhaust port 22 through the connection pipe 32 is beneficial to improving the tightness of the vacuum device 30 and avoiding The gas leakage affects the negative pressure in the cooking cavity 11.
根据本申请的一个具体实施例,如图2所示,真空装置30还包括电磁阀33,电磁阀33设置在盖体20上并通过连接管32连通抽气口21和真空泵31,即电磁阀33设置在抽气口21和真空泵31之间。利用电磁阀33控制真空泵31与抽气口21之间的连通与断开,可以保证真空泵31能够顺利抽出蒸汽,有利于控制烹饪腔11内的气压。According to a specific embodiment of the present application, as shown in FIG. 2, the vacuum device 30 further includes an electromagnetic valve 33. The electromagnetic valve 33 is disposed on the cover 20 and communicates with the suction port 21 and the vacuum pump 31 through the connecting pipe 32, that is, the electromagnetic valve 33. It is provided between the suction port 21 and the vacuum pump 31. The use of the electromagnetic valve 33 to control the communication between the vacuum pump 31 and the air outlet 21 can ensure that the vacuum pump 31 can smoothly extract steam, which is beneficial to controlling the air pressure in the cooking cavity 11.
基于图1-2实施例的烹饪器具,本申请实施例提出了一种烹饪器具的烹饪控制方法。Based on the cooking appliance of the embodiment of FIGS. 1-2, an embodiment of the present application proposes a cooking control method for a cooking appliance.
图3为根据本申请实施例的烹饪器具的烹饪控制方法的流程图。如图3所示,烹饪器具的烹饪控制方法包括以下步骤:3 is a flowchart of a cooking control method for a cooking appliance according to an embodiment of the present application. As shown in FIG. 3, the cooking control method of a cooking appliance includes the following steps:
S1:在烹饪器具的烹饪过程中,检测烹饪器具的烹饪参数,其中,烹饪过程包括预处理阶段、升温沸腾阶段和高温沸腾阶段,烹饪参数包括烹饪腔内的温度、烹饪腔内的压力和升温沸腾阶段的运行时间中的至少一个。S1: During the cooking process of the cooking appliance, the cooking parameters of the cooking appliance are detected, wherein the cooking process includes a pretreatment phase, a heating boiling phase, and a high temperature boiling phase, and the cooking parameters include the temperature in the cooking cavity, the pressure in the cooking cavity, and the heating At least one of the runtimes of the boiling phase.
具体地,可通过设置在锅体底部的温度检测单元例如温度传感器实时检测烹饪腔内的温度或者通过设置在盖体内的温度检测单元例如温度传感器实时检测烹饪腔内的温度。并且,可通过压力检测单元例如压力传感器实时检测烹饪腔内的压力。Specifically, the temperature in the cooking cavity may be detected in real time by a temperature detection unit such as a temperature sensor provided at the bottom of the pot body or the temperature in the cooking cavity may be detected in real time by a temperature detection unit such as a temperature sensor provided in the lid body. And, the pressure in the cooking cavity can be detected in real time by a pressure detection unit such as a pressure sensor.
可以理解的是,电饭煲在煮饭时的烹饪过程可以包括但不限于预处理阶段、升温沸腾阶段和高温沸腾阶段。其中,如图4所示,在进入升温沸腾阶段之前,电饭煲先进入预处理阶段,其中,在预处理阶段,可进行吸水控制,即从常温加热到吸水温度并保持吸水温度预设吸水时间,以使米粒进行吸水,从而可以缩短煮饭时间,改善烹饪器具所烹饪米饭的口感,或者,在预处理阶段也可不进行吸水控制,即从常温直接加热到进入升温沸腾阶段的温度,例如后面提到的第一温度值,此外,在预处理阶段也可控制真空装置进行抽真空以提高吸水率;在升温沸腾阶段之后,进入高温沸腾阶段,在高温沸腾阶段,烹饪腔内处于非负压状态例如常压状态,烹饪腔能够维持较高温度沸腾,即例如以外部大气压下沸点(100℃左右)的温度维持沸腾,将米饭煮熟。其中,升温沸腾阶段将在下面的实施例中 详细说明。It can be understood that the cooking process of the rice cooker during cooking may include, but is not limited to, a pretreatment stage, a temperature-boiling stage, and a high-temperature boiling stage. Among them, as shown in FIG. 4, before entering the temperature-boiling stage, the rice cooker first enters a pretreatment stage. Among the pretreatment stages, water absorption control can be performed, that is, heating from normal temperature to the water absorption temperature and maintaining the water absorption temperature for a preset water absorption time. In order to make the rice grains absorb water, the cooking time can be shortened, and the taste of the rice cooked by the cooking appliance can be improved, or the water absorption control can not be performed during the pretreatment stage, that is, the temperature is directly heated from the normal temperature to the temperature at the boiling stage, such as In addition to the first temperature value reached, in addition, the vacuum device can also be controlled to increase the water absorption rate during the pre-treatment phase; after the temperature-boiling phase, the high-temperature boiling phase is entered. During the high-temperature boiling phase, the cooking cavity is in a non-negative pressure state. For example, in a normal pressure state, the cooking cavity can maintain boiling at a high temperature, that is, boiling at a temperature of the boiling point (about 100 ° C.) at an external atmospheric pressure to cook the rice. The temperature-boiling stage will be described in detail in the following examples.
另外,烹饪过程还可以包括焖饭阶段,可理解,在高温沸腾阶段之后,进入焖饭阶段,在高温沸腾阶段,烹饪腔内处于非负压状态例如常压状态,烹饪腔能够维持在焖饭温度,焖饭温度低于高温沸腾阶段的温度,提升米饭的口感。In addition, the cooking process may also include a rice cooking phase. It is understood that after the high-temperature boiling phase, the rice cooking phase is entered. In the high-temperature boiling phase, the cooking cavity is in a non-negative pressure state, such as a normal pressure state, and the cooking cavity can be maintained at the rice cooking status. The temperature, the temperature of the rice is lower than the temperature of the high-temperature boiling stage, which improves the taste of the rice.
S2:当烹饪器具处于升温沸腾阶段时,控制加热装置进行加热工作,并控制真空装置对烹饪腔进行抽真空,以使烹饪腔在烹饪腔内的温度达到第一温度值或大于第一温度值预设阈值时产生沸腾气泡,并根据烹饪腔内的温度、烹饪腔内的压力和升温沸腾阶段的运行时间中至少一个控制真空装置关闭,直至烹饪器具进入所述高温沸腾阶段。S2: When the cooking appliance is in the boiling stage, control the heating device to perform heating work, and control the vacuum device to evacuate the cooking cavity, so that the temperature of the cooking cavity in the cooking cavity reaches a first temperature value or greater than the first temperature value Boiling bubbles are generated at a preset threshold, and the vacuum device is controlled to close according to at least one of the temperature in the cooking cavity, the pressure in the cooking cavity, and the operating time of the heating and boiling phase, until the cooking appliance enters the high-temperature boiling phase.
需要说明的是,在烹饪过程中,烹饪腔内的温度分布并不均匀。由于烹饪器具中的加热装置输出的热量是从底部逐渐往上传递,因此,烹饪腔的温度呈现一种分层状态。具体地,由于烹饪腔底部与加热装置是直接接触,烹饪腔底部的温度最高,中部的温度次之,烹饪腔顶部的温度最低。It should be noted that during the cooking process, the temperature distribution in the cooking cavity is not uniform. Since the heat output from the heating device in the cooking appliance is gradually transferred from the bottom to the top, the temperature of the cooking cavity presents a layered state. Specifically, since the bottom of the cooking cavity is in direct contact with the heating device, the temperature at the bottom of the cooking cavity is the highest, the temperature in the middle is second, and the temperature at the top of the cooking cavity is the lowest.
由于烹饪腔内的温度存在分层的现象,因此,烹饪腔底部会最先达到沸点进而产生气泡,通过产生的气泡来搅动米粒。但是由于中部和顶部的温度此时是低于底部的,因此中部和顶部的温度并未到达的沸点,整个烹饪腔也未真正进入沸腾。换言之,本申请实施例中,“产生沸腾气泡”可理解为,在烹饪腔内的最高温度即烹饪腔底部温度达到沸点而产生沸腾气泡时,即认为是烹饪腔内产生沸腾气泡,也就是说,烹饪腔底部产生沸腾气泡即认为是烹饪腔内产生沸腾气泡,无需整个烹饪腔均进入沸腾。Because the temperature in the cooking cavity is delaminated, the bottom of the cooking cavity will first reach the boiling point and generate air bubbles, and the generated air bubbles will stir the rice grains. But because the temperature of the middle and top is lower than the bottom at this time, the temperature of the middle and top has not reached the boiling point, and the entire cooking cavity has not really entered the boiling. In other words, in the embodiment of the present application, “boiling bubbles are generated” can be understood as when the highest temperature in the cooking cavity, that is, the temperature at the bottom of the cooking cavity reaches the boiling point, and boiling bubbles are generated, it is considered that boiling bubbles are generated in the cooking cavity, that is, If boiling bubbles are generated at the bottom of the cooking cavity, it is considered that boiling bubbles are generated in the cooking cavity, and it is not necessary for the entire cooking cavity to enter boiling.
具体到本实施例中,以“在烹饪腔内的温度达到第一温度值时烹饪腔内产生沸腾气泡”为例,只要烹饪腔底部温度达到沸点即可认为产生沸腾气泡,因此,第一温度值可以是低于沸点的某一温度值,例如,以设置在盖体上的温度检测单元检测到的温度作为烹饪腔内的温度时,由于底部温度达到沸点时,设置在盖体上的温度检测单元检测到的温度未达到沸点,因此,即使第一温度值未达到当前压力下的沸点,但鉴于烹饪腔底部温度已经达到沸点,也认为烹饪腔内产生沸腾气泡。举例来说,水在40kpa的压力值时沸点为76℃,当烹饪腔内的气压维持在40kpa左右的负压值下,由于气泡的产生要在整个烹饪腔进入沸腾以前,当烹饪腔内的温度达到60℃时,即开始产生气泡。Specifically in this embodiment, taking “the boiling bubble is generated in the cooking cavity when the temperature in the cooking cavity reaches the first temperature value” as an example, as long as the temperature at the bottom of the cooking cavity reaches the boiling point, it can be considered that boiling bubbles are generated. Therefore, the first temperature The value may be a certain temperature value lower than the boiling point. For example, when the temperature detected by the temperature detection unit provided on the cover is used as the temperature in the cooking cavity, the temperature set on the cover when the bottom temperature reaches the boiling point The temperature detected by the detection unit has not reached the boiling point. Therefore, even if the first temperature value does not reach the boiling point at the current pressure, it is considered that boiling bubbles are generated in the cooking cavity in view of the temperature at the bottom of the cooking cavity. For example, the boiling point of water at a pressure of 40kpa is 76 ° C. When the air pressure in the cooking cavity is maintained at a negative pressure of about 40kpa, the generation of bubbles must be before the entire cooking cavity enters boiling. When the temperature reaches 60 ° C, bubbles start to form.
根据本申请的一个实施例,可通过烹饪腔内的温度确定烹饪器具的升温沸腾阶段,其中,在烹饪腔内的温度达到第一温度值时,确定烹饪器具进入升温沸腾阶段,其中,第一温度值小于大气压沸点。具体地,第一温度值根据米的糊化温度确定。According to an embodiment of the present application, the temperature-boiling phase of the cooking appliance can be determined by the temperature in the cooking cavity. When the temperature in the cooking cavity reaches a first temperature value, it is determined that the cooking appliance enters the temperature-boiling phase. The temperature is less than the atmospheric boiling point. Specifically, the first temperature value is determined according to the gelatinization temperature of the rice.
根据本申请的一个实施例,第一温度值可小于或等于米的糊化温度值Te,其中,米的 糊化温度值Te的取值范围可为50℃<te<70℃。需要说明的是,米粒受热后,在一定温度范围内,米粒开始破坏,体积膨大,粘度急剧上升,米粒发生糊化,由此,米粒发生糊化时所需的温度称为糊化温度。According to an embodiment of the present application, the first temperature value may be less than or equal to the gelatinization temperature value Te of the rice, and the range of the gelatinization temperature value Te of the rice may be 50 ° C <te <70 ° C. It should be noted that after the rice grains are heated, within a certain temperature range, the rice grains start to break, the volume expands, the viscosity rises sharply, and the rice grains gelatinize. Therefore, the temperature required when the rice grains gelatinize is called the gelatinization temperature.
可以理解的是,第一温度值可为固定值,也可根据不同的米种选取不同的值,例如,不同的米种对应不同的糊化温度,进而不同米种可对应不同的第一温度值,即根据多种米种的糊化温度设置多个第一温度值,在煮饭时根据所用的米种选择相应的第一温度值;又如,可综合考虑多种米种的糊化温度以得到一个温度值,并将该温度值作为第一温度值。It can be understood that the first temperature value may be a fixed value, or different values may be selected according to different rice types. For example, different rice types correspond to different gelatinization temperatures, and different rice types may correspond to different first temperatures. Value, that is, multiple first temperature values are set according to the gelatinization temperature of multiple rice types, and the corresponding first temperature value is selected according to the rice type used in cooking; for another example, the gelatinization of multiple rice types may be considered comprehensively Temperature to get a temperature value, and use this temperature value as the first temperature value.
根据本申请的一个实施例,第一温度值可为55℃~65℃。也就是说,第一温度值T1可在大于55℃且小于65℃的范围内选取。例如,第一温度值T1可为60℃或62℃。According to an embodiment of the present application, the first temperature value may be 55 ° C to 65 ° C. That is, the first temperature value T1 can be selected within a range of greater than 55 ° C and less than 65 ° C. For example, the first temperature value T1 may be 60 ° C or 62 ° C.
进一步地,根据本申请的一个实施例,当烹饪器具处于升温沸腾阶段时,通过控制加热装置以使烹饪腔内的温度从第一温度值上升到第二温度值,其中,第二温度值大于第一温度值且小于或等于大气压沸点。具体地,第二温度值可以根据大气压沸点确定,即第二温度值可为接近大气压沸点的温度值,例如100℃或98℃。Further, according to an embodiment of the present application, when the cooking appliance is in a heating and boiling phase, the heating device is controlled to increase the temperature in the cooking cavity from a first temperature value to a second temperature value, where the second temperature value is greater than The first temperature value is less than or equal to the atmospheric pressure boiling point. Specifically, the second temperature value may be determined according to the atmospheric pressure boiling point, that is, the second temperature value may be a temperature value close to the atmospheric pressure boiling point, for example, 100 ° C. or 98 ° C.
也就是说,整个升温沸腾阶段,烹饪腔内的温度从第一温度值开始上升,且烹饪腔内的温度处于第一温度值到第二温度值的范围内,即温度大于米的糊化温度Te且小于第二温度值例如98℃的温度段可作为升温沸腾阶段,或者,经过预设吸水时长后但温度小于98℃的温度段则为升温沸腾阶段。That is, throughout the heating and boiling phase, the temperature in the cooking cavity starts to rise from the first temperature value, and the temperature in the cooking cavity is in the range of the first temperature value to the second temperature value, that is, the temperature is greater than the gelatinization temperature of the rice. The temperature section where Te is less than the second temperature value, for example, 98 ° C., can be used as the temperature-boiling stage, or the temperature section after the preset water absorption period but the temperature is less than 98 ° C. is the temperature-boiling stage.
由此,本申请实施例的烹饪控制方法,在升温沸腾阶段,即从第一温度值开始至第二温度值的范围内,控制真空装置对烹饪腔进行抽真空以使烹饪腔内形成负压真空,使沸腾温度降至米粒未开始糊化或刚开始糊化的温度附近,即“低温沸腾”,烹饪腔在较低温度即大米糊化但未粘结成团前时产生沸腾气泡,从而确保米粒不结块,保持松散透热。Therefore, in the cooking control method of the embodiment of the present application, in the temperature-boiling stage, that is, from the first temperature value to the second temperature value, controlling the vacuum device to evacuate the cooking cavity to form a negative pressure in the cooking cavity. The vacuum reduces the boiling temperature to near the temperature at which the rice grains do not begin to gelatinize or just begin to gelatinize, that is, "low temperature boiling". The cooking cavity generates boiling air bubbles at a lower temperature, that is, before the rice gelatinizes but does not stick to a mass. Make sure that the rice grains are not agglomerated and keep loose and diathermy.
但是,本申请申请人发现,在升温沸腾阶段,如果过早关闭真空装置,打开泄装置使得烹饪腔内的压力与外部大气压一致,米水不能够很好沸腾。如果太迟关闭真空装置,沸腾后产生的水蒸气就会吸入真空装置例如真空泵内后排出,烹饪腔腔内的湿度下降,同时部分物质残留在真空泵内,易滋生细菌。However, the applicant of the present application has found that if the vacuum device is closed prematurely and the vent device is opened during the temperature-boiling stage, the pressure in the cooking cavity is consistent with the external atmospheric pressure, and the rice water cannot boil well. If the vacuum device is turned off too late, the water vapor generated after boiling will be sucked into the vacuum device, such as a vacuum pump, and discharged. The humidity in the cooking cavity will drop, and some substances will remain in the vacuum pump, which will easily breed bacteria.
基于此,在本申请实施例中,在升温沸腾阶段,根据烹饪腔内的温度、烹饪腔内的压力和升温沸腾阶段的运行时间中至少一个综合控制真空装置关闭,停止抽取烹饪腔内的气体,从而,能够在恰当的时刻停止抽取烹饪腔内的气体,实现更好的沸腾翻滚,同时防止沸腾后产生的水蒸气流失和吸入真空装置,防止滋生细菌。Based on this, in the embodiment of the present application, in the heating and boiling phase, at least one of the integrated control of the vacuum device is closed according to the temperature in the cooking cavity, the pressure in the cooking cavity, and the operating time of the heating and boiling phase, and the extraction of the gas in the cooking cavity is stopped. Therefore, it is possible to stop extracting the gas in the cooking cavity at an appropriate time, to achieve better boiling and tumbling, and to prevent water vapor generated after boiling and sucking into a vacuum device, and to prevent breeding of bacteria.
下面详细说明控制真空装置关闭的具体控制方式。The specific control method for controlling the closing of the vacuum device will be described in detail below.

Specifically, controlling the closing of the vacuum device according to the temperature in the cooking cavity includes: controlling the vacuum device to close when the temperature in the cooking cavity is greater than or equal to a preset closing temperature.
也就是说,在升温沸腾阶段,当烹饪腔内的温度大于或等于预设关闭温度时,关闭真空装置,停止抽取烹饪腔内的气体,从而,能够在恰当的时刻停止抽取烹饪腔内的气体,实现更好的沸腾翻滚,同时防止沸腾后产生的水蒸气流失和吸入真空装置,防止滋生细菌。That is to say, in the temperature-boiling phase, when the temperature in the cooking cavity is greater than or equal to a preset shutdown temperature, the vacuum device is turned off to stop extracting the gas in the cooking cavity, so that the extraction of the gas in the cooking cavity can be stopped at an appropriate time. , To achieve better boiling and tumbling, at the same time to prevent the loss of water vapor generated after boiling and suction into the vacuum device, to prevent the breeding of bacteria.
具体地,根据本申请的另一个实施例,根据所述烹饪腔内的温度的变化趋势控制所述真空装置关闭包括:Specifically, according to another embodiment of the present application, controlling the turning off of the vacuum device according to a temperature change trend in the cooking cavity includes:
获取所述烹饪腔内的温度在预设采样时间内上升速率;Obtaining a rate of temperature rise in the cooking cavity within a preset sampling time;
当所述温度在预设采样时间内上升速率小于预设温度上升速率时,控制所述真空装置关闭。When the temperature rise rate is less than the preset temperature rise rate within the preset sampling time, the vacuum device is controlled to be turned off.
需要说明的是,假设每隔预设采样时间采集一次温度,那么相邻两个温度的温度差值与预设采样时间的比值,即为烹饪腔内的温度在预设采样时间内上升速率。It should be noted that, assuming that the temperature is collected every preset sampling time, the ratio of the temperature difference between two adjacent temperatures to the preset sampling time is the rising rate of the temperature in the cooking cavity during the preset sampling time.
也就是说,在升温沸腾阶段,当烹饪腔内的温度在预设采样时间内上升速率小于预设温度上升速率时,关闭真空装置,停止抽取烹饪腔内的气体,从而,能够在恰当的时刻停止抽取烹饪腔内的气体,实现更好的沸腾翻滚,同时防止沸腾后产生的水蒸气流失和吸入真空装置,防止滋生细菌。In other words, in the temperature-boiling phase, when the temperature in the cooking cavity rises less than the preset temperature rise rate within a preset sampling time, the vacuum device is turned off to stop extracting the gas in the cooking cavity, so that it can be at an appropriate time. Stop extracting the gas in the cooking cavity to achieve better boiling and tumbling, at the same time prevent the loss of water vapor generated after boiling and suck into the vacuum device, and prevent the breeding of bacteria.
需要说明的是,关闭真空装置可包括关闭真空泵且关闭电磁阀。It should be noted that closing the vacuum device may include closing a vacuum pump and closing a solenoid valve.
进一步地,根据本申请的一个实施例,烹饪器具的烹饪控制方法还包括:Further, according to an embodiment of the present application, the cooking control method of the cooking appliance further includes:

根据烹饪腔内的米水量确定预设关闭温度或预设温度上升速率。The preset shutdown temperature or the preset temperature rise rate is determined according to the amount of rice water in the cooking cavity.
可以理解的是,不同米水量,其停止抽真空即关闭真空装置的预设关闭温度或预设温度上升速率不同。也就是说,在升温沸腾阶段之前可确定烹饪腔内的米水量,在升温沸腾阶段,即可根据烹饪腔内的米水量确定预设关闭温度或预设温度上升速率。It can be understood that the preset shut-off temperature or the preset temperature rise rate of the vacuum device is different when the amount of water in the meter is stopped and the vacuum is turned off. That is, the amount of rice water in the cooking cavity can be determined before the heating and boiling phase, and the preset closing temperature or the preset temperature rising rate can be determined according to the rice water in the cooking cavity during the heating and boiling phase.
其中,预设关闭温度与米水量呈正相关关系,即预设关闭温度随着米水量的增加而增加,而预设温度上升速率与米水量呈负相关关系,即预设关闭温度随着米水量的增加而减小。Among them, the preset shutdown temperature has a positive correlation with the amount of rice water, that is, the preset shutdown temperature increases as the amount of rice water increases, and the preset temperature rise rate has a negative correlation with the amount of rice water, that is, the preset shutdown temperature increases with the amount of rice water. Increase and decrease.
在一个具体示例中,可在预处理阶段判断出米水量,例如可通过控制加热装置使烹饪腔内的温度从第一设定温度例如常温升高到第二设定温度,并记录从第一设定温度升高到 第二设定温度的时间,根据时间确定米水量。或在进行烹饪之前可通过称重来判断米水量。In a specific example, the amount of rice water can be determined in the pre-processing stage, for example, the temperature in the cooking cavity can be raised from a first set temperature, such as normal temperature to a second set temperature, by controlling the heating device, and recorded from the first When the set temperature rises to the second set temperature, the amount of rice water is determined according to the time. Or you can determine the amount of rice water by weighing before cooking.
在本申请的一个实施例,可将米水量分为多个米水量等级,例如烹饪腔内的米水量小于第一米水量,可确定米水量等级为小量;烹饪腔内的米水量大于等于所述第一米水量且小于第二米水量,可确定米水量等级为中量;烹饪腔内的米水量大于等于所述第一米水量且小于第二米水量,可确定米水量等级为大量。并且,多个米水量等级可分别与多个预设关闭温度对应,同时多个米水量等级还分别与多个预设温度上升速率对应。由此,可先确定烹饪腔内的米水量等级,并通过查表确定米水量等级对应的预设关闭温度或预设温度上升速率。In an embodiment of the present application, the amount of rice water can be divided into multiple rice water levels, for example, the rice water amount in the cooking cavity is less than the first rice water amount, and the rice water amount level can be determined to be small; the rice water amount in the cooking cavity is greater than or equal to The first rice water quantity is less than the second rice water quantity, and the rice water quantity grade can be determined to be medium; the rice water quantity in the cooking cavity is greater than or equal to the first rice water quantity and less than the second rice water quantity, and it can be determined that the rice water quantity grade is large. . In addition, multiple rice water volume levels may correspond to multiple preset shutdown temperatures, respectively, and multiple rice water volume levels may also correspond to multiple preset temperature rise rates, respectively. Therefore, the rice water quantity level in the cooking cavity can be determined first, and a preset closing temperature or a preset temperature rising rate corresponding to the rice water quantity level can be determined through a look-up table.
在本申请的一个具体实施例中,烹饪腔内的米水量与预设关闭温度、预设温度上升速率的对应可如下表1所示。In a specific embodiment of the present application, the correspondence between the amount of rice water in the cooking cavity, the preset shutdown temperature, and the preset temperature rise rate can be shown in Table 1 below.
表1Table 1

如上表1,当烹饪腔内的米水量小于第一米水量即米水量等级为小量时,预设关闭温度为55℃~60℃,预设温度上升速率为3℃/60s~6℃/60s;当烹饪腔内的米水量大于等于第一米水量且小于第二米水量即米水量等级为中量时,预设关闭温度为60℃~65℃,预设温度上升速率为2℃/60s~5℃/60s;当烹饪腔内的米水量大于第二米水量即米水量等级为大量时,预设关闭温度为65℃~70℃,预设温度上升速率为1℃/60s~3℃/60s。As shown in Table 1, when the amount of rice water in the cooking cavity is less than the first rice water quantity, that is, the rice water quantity level is small, the preset shutdown temperature is 55 ° C to 60 ° C, and the preset temperature rise rate is 3 ° C / 60s to 6 ° C / 60s; when the amount of rice water in the cooking cavity is greater than or equal to the first rice water amount and less than the second rice water amount, that is, the rice water level is medium, the preset shutdown temperature is 60 ° C to 65 ° C, and the preset temperature rise rate is 2 ° C 60s ~ 5 ℃ / 60s; when the amount of rice water in the cooking cavity is greater than the second rice water quantity, that is, the rice water quantity level is large, the preset shutdown temperature is 65 ℃ ~ 70 ℃, and the preset temperature rise rate is 1 ℃ / 60s ~ 3 ℃ / 60s.
如上所述,如图4所示,本申请实施例的烹饪器具的烹饪过程可包括预处理阶段、升温沸腾阶段、高温沸腾阶段和焖饭阶段。As described above, as shown in FIG. 4, the cooking process of the cooking appliance according to the embodiment of the present application may include a pretreatment stage, a temperature-boiling stage, a high-temperature boiling stage, and a rice cooking stage.
具体地,在预处理阶段,可控制加热装置进行加热工作以使烹饪腔内的温度逐渐升高,当烹饪腔内的温度达到第一温度值时进入升温沸腾阶段。或者,在预处理阶段,记录预处理阶段的运行时间,并控制加热装置进行加热工作以使烹饪腔内的温度维持在预设吸水温度例如55℃以使米粒充分吸水,在预处理阶段的运行时间达到预设吸水时间例如10分钟时,控制加热装置进行加热工作以使烹饪腔内的温度继续升高,当烹饪腔内的温度达到第一温度值时进入升温沸腾阶段(如图4中的温度变化曲线)。并且,在预处理阶段,可控制真空装置进行抽真空,以降低烹饪腔内的压力(如图4中的压力变化曲线),使米粒更多容易吸水,或者,也可控制真空装置不进行抽真空,即不降低烹饪腔内的压力,利用温度升高来促进米粒吸水。Specifically, in the pre-processing stage, the heating device may be controlled to perform heating work so that the temperature in the cooking cavity is gradually increased, and when the temperature in the cooking cavity reaches a first temperature value, the heating and boiling phase is entered. Alternatively, during the pre-processing phase, the running time of the pre-processing phase is recorded, and the heating device is controlled to perform the heating work so that the temperature in the cooking cavity is maintained at a preset water absorption temperature, such as 55 ° C, so that the rice grains fully absorb water. When the time reaches the preset water absorption time, for example, 10 minutes, the heating device is controlled to perform the heating operation so that the temperature in the cooking cavity continues to rise, and when the temperature in the cooking cavity reaches the first temperature value, the heating and boiling phase is entered (as shown in FIG. 4). Temperature curve). Also, in the pre-processing stage, the vacuum device can be controlled to evacuate to reduce the pressure in the cooking cavity (as shown in the pressure change curve in FIG. 4), so that the rice grains are more likely to absorb water, or the vacuum device can be controlled not to perform vacuum Vacuum, that is, does not reduce the pressure in the cooking cavity, uses the temperature increase to promote the rice grains to absorb water.
在升温沸腾阶段,通过控制加热装置可以使烹饪腔内的温度从第一温度值开始上升至 第二温度值,并且控制真空装置对烹饪腔进行抽真空以使烹饪腔内形成负压真空,烹饪腔在较低温度即大米糊化但未粘结成团前时产生沸腾气泡,从而确保米粒不结块,保持松散透热。其中,烹饪腔内米水不断沸腾产生大量的蒸汽,使烹饪腔内的压力无法维持在低气压而逐渐上升。In the heating and boiling phase, the temperature in the cooking cavity can be raised from the first temperature value to the second temperature value by controlling the heating device, and the vacuum device is controlled to evacuate the cooking cavity to form a negative pressure vacuum in the cooking cavity. The cavity generates boiling air bubbles at a lower temperature, that is, before the rice is gelatinized but not bonded into a mass, thereby ensuring that the rice grains do not agglomerate and keep loose heat. Among them, the rice water in the cooking cavity is constantly boiling to generate a large amount of steam, so that the pressure in the cooking cavity cannot be maintained at a low air pressure and gradually rises.
并且,在烹饪腔内的温度大于或等于预设关闭温度或烹饪腔内的温度在预设采样时间内上升速率小于预设温度上升速率时,控制真空装置关闭,并根据控制烹饪器具的状态控制泄压装置对烹饪腔进行泄气,使烹饪器具恢复到常压状态,迁移到高温沸腾阶段。In addition, when the temperature in the cooking cavity is greater than or equal to a preset shutdown temperature or the temperature in the cooking cavity rises within a preset sampling time and is less than a preset temperature rise rate, the vacuum device is controlled to be turned off and controlled according to the state of the control cooking appliance The pressure relief device deflate the cooking cavity, restore the cooking utensil to a normal pressure state, and migrate to a high-temperature boiling stage.
在高温沸腾阶段,由于沸腾的气孔和通道已经形成,不需要抽真空降低烹饪腔内的压力,可控制真空装置一直处于关闭状态,并且通过控制加热装置以第一功率进行加热,以使加热装置维持在预设沸腾温度,例如大气压沸点附近的温度或者高于98℃的温度,从而,烹饪腔内的米水维持高温沸腾状态,确保将米饭煮熟。并且,在高温沸腾阶段的运行时间达到预设高温沸腾时间之后,进入焖饭阶段。In the high-temperature boiling stage, since the boiling pores and channels have been formed, there is no need to evacuate to reduce the pressure in the cooking cavity. The vacuum device can be controlled to be always closed, and the heating device can be heated at the first power to control the heating device. Maintaining a preset boiling temperature, such as a temperature near the boiling point of atmospheric pressure or a temperature higher than 98 ° C, so that the rice water in the cooking cavity maintains a high-temperature boiling state to ensure that the rice is cooked. In addition, after the operating time of the high-temperature boiling stage reaches a preset high-temperature boiling time, it enters a rice cooking stage.
在焖饭阶段,同样不需要抽真空降低烹饪腔内的压力,可控制真空装置一直处于关闭状态,并且通过控制加热装置以第二功率进行加热,以使加热装置维持在预设焖饭温度,例如大于第一温度值且小于第二温度值,从而,使米饭的香味和甜味更充足。其中,第二功率小于第一功率。In the rice cooking phase, it is also unnecessary to evacuate to reduce the pressure in the cooking cavity. The vacuum device can be controlled to be always turned off, and the heating device is controlled to be heated at a second power to maintain the heating device at a preset rice cooking temperature. For example, it is larger than the first temperature value and smaller than the second temperature value, so that the aroma and sweetness of the rice are more sufficient. The second power is smaller than the first power.
另外,如图5所示,本申请一个具体实施例的控制真空装置关闭的方法包括以下步骤:In addition, as shown in FIG. 5, a method for controlling shutdown of a vacuum device according to a specific embodiment of the present application includes the following steps:
S101:进入升温沸腾阶段。S101: Enter the temperature-boiling stage.
S102:获取米水量等级,获取烹饪腔内的温度,并根据米水量等级确定预设关闭温度或预设温度上升速率。S102: Obtain a rice water volume level, obtain a temperature in the cooking cavity, and determine a preset shutdown temperature or a preset temperature rise rate according to the rice water volume level.
S103:判断烹饪腔内的温度是否大于预设关闭温度或者温度在预设采样时间内上升速率是否小于预设温度上升速率。S103: Determine whether the temperature in the cooking cavity is greater than a preset shutdown temperature or whether the temperature rise rate is less than a preset temperature rise rate within a preset sampling time.
如果是,则执行步骤S104;如果否,则返回步骤S103。If yes, go to step S104; if no, go back to step S103.
S104:控制真空装置关闭。S104: Control the vacuum device to close.
S105:继续进行烹饪。S105: Continue cooking.
在前述实施例中,根据烹饪腔内的温度或烹饪腔内的温度的变化趋势控制真空装置关闭之后,真空装置将不再开启直至烹饪结束,即真空装置在后续的高温沸腾阶段和焖饭装置也将保持关闭。In the foregoing embodiment, after the vacuum device is controlled to be turned off according to the temperature in the cooking cavity or the temperature trend in the cooking cavity, the vacuum device will not be turned on until the end of cooking, that is, the vacuum device will be in the subsequent high-temperature boiling stage and the rice cooking device. It will also remain closed.
由此,在本申请实施例中,在升温沸腾阶段,当腔内温度大于等于预设温度时,或者温度上升速率变慢时,关闭真空装置,停止抽取烹饪腔内的气体,从而,能够在恰当的时 刻停止抽取烹饪腔内的气体,实现更好的沸腾翻滚,同时防止沸腾后产生的水蒸气流失和吸入真空装置,防止滋生细菌。Therefore, in the embodiment of the present application, when the temperature in the cavity is greater than or equal to a preset temperature or the temperature rise rate is slowed, the vacuum device is turned off to stop extracting the gas in the cooking cavity. Stop the extraction of gas in the cooking cavity at the right moment to achieve better boiling and tumbling, and at the same time prevent the loss of water vapor generated after boiling and suck into the vacuum device to prevent breeding of bacteria.

Prevent breeding of bacteria.
具体地,根据本申请的另一个实施例,根据所述烹饪腔内的压力的变化趋势控制所述真空装置关闭包括:Specifically, according to another embodiment of the present application, controlling the closing of the vacuum device according to a change trend of the pressure in the cooking cavity includes:

当所述压力在预设采样时间内上升速率大于预设压力上升速率时,控制所述真空装置关闭。When the pressure rise rate is greater than the preset pressure rise rate within the preset sampling time, the vacuum device is controlled to be turned off.
需要说明的是,假设每隔预设采样时间采集一次压力,那么相邻两个压力的压力差值与预设采样时间的比值,即为烹饪腔内的压力在预设采样时间内上升速率。It should be noted that, assuming that the pressure is collected every preset sampling time, the ratio of the pressure difference between two adjacent pressures and the preset sampling time is the rising rate of the pressure in the cooking cavity during the preset sampling time.
也就是说,在升温沸腾阶段,当烹饪腔内的压力在预设采样时间内上升速率大于预设压力上升速率时,关闭真空装置,停止抽取烹饪腔内的气体,从而,能够在恰当的时刻停止抽取烹饪腔内的气体,实现更好的沸腾翻滚,同时防止沸腾后产生的水蒸气流失和吸入真空装置,防止滋生细菌。That is to say, in the temperature-boiling phase, when the pressure in the cooking cavity rises faster than the preset pressure in the preset sampling time, the vacuum device is turned off to stop the extraction of the gas in the cooking cavity, so that it can be at an appropriate time.

可以理解的是,不同米水量,其停止抽真空即关闭真空装置的预设关闭压力或预设压力上升速率不同。也就是说,在升温沸腾阶段之前可确定烹饪腔内的米水量,在升温沸腾阶段,即可根据烹饪腔内的米水量确定预设关闭压力或预设压力上升速率。It can be understood that the preset closing pressure or the rate of rising of the preset pressure of the vacuum device is different depending on the amount of water in the meter. That is, the amount of rice water in the cooking cavity can be determined before the heating and boiling phase, and the preset closing pressure or the preset pressure rising rate can be determined according to the rice water in the cooking cavity during the heating and boiling phase.
其中,预设关闭压力与米水量呈正相关关系,即预设关闭压力随着米水量的增加而增 加。Among them, the preset closing pressure has a positive correlation with the amount of rice water, that is, the preset closing pressure increases as the amount of rice water increases.

Or you can determine the amount of rice water by weighing before cooking.
在本申请的一个实施例,可将米水量分为多个米水量等级,例如烹饪腔内的米水量小于第一米水量,可确定米水量等级为小量;烹饪腔内的米水量大于等于所述第一米水量且小于第二米水量,可确定米水量等级为中量;烹饪腔内的米水量大于等于所述第一米水量且小于第二米水量,可确定米水量等级为大量。并且,多个米水量等级可分别与多个预设关闭压力对应,同时多个米水量等级还分别与多个预设温度上升速率对应。由此,可先确定烹饪腔内的米水量等级,并通过查表确定米水量等级对应的预设关闭压力或预设压力上升速率。In an embodiment of the present application, the amount of rice water can be divided into multiple rice water levels, for example, the rice water amount in the cooking cavity is less than the first rice water amount, and the rice water amount level can be determined to be small; the rice water amount in the cooking cavity is greater than or equal to The first rice water quantity is less than the second rice water quantity, and the rice water quantity grade can be determined to be medium; the rice water quantity in the cooking cavity is greater than or equal to the first rice water quantity and less than the second rice water quantity, and it can be determined that the rice water quantity grade is large. .

Therefore, the rice water quantity level in the cooking cavity can be determined first, and a preset closing pressure or a preset pressure rising rate corresponding to the rice water quantity level can be determined by looking up a table.
在本申请的一个具体实施例中,烹饪腔内的米水量与预设关闭压力的对应可如下表2所示。In a specific embodiment of the present application, the correspondence between the amount of rice water in the cooking cavity and the preset closing pressure can be shown in Table 2 below.

如上所述,如图4所示,本申请实施例的烹饪器具的烹饪过程可包括预处理阶段、升温沸腾阶段、高温沸腾阶段和焖饭阶段。As described above, as shown in FIG. 4, the cooking process of the cooking appliance according to the embodiment of the present application may include a pretreatment stage, a temperature-boiling stage, a high-temperature boiling stage, and a rice cooking stage.
具体地,在预处理阶段,可控制加热装置进行加热工作以使烹饪腔内的温度逐渐升高,当烹饪腔内的温度达到第一温度值时进入升温沸腾阶段。或者,在预处理阶段,记录预处理阶段的运行时间,并控制加热装置进行加热工作以使烹饪腔内的温度维持在预设吸水温度例如55℃以使米粒充分吸水,在预处理阶段的运行时间达到预设吸水时间例如10分钟时,控制加热装置进行加热工作以使烹饪腔内的温度继续升高,当烹饪腔内的温度达到第一温度值时进入升温沸腾阶段(如图4中的温度变化曲线)。并且,在预处理阶段,可控制真空装置进行抽真空,以降低烹饪腔内的压力(如图4中的压力变化曲线),使米粒更多容易吸水,或者,也可控制真空装置不进行抽真空,即不降低烹饪腔内的压力,利用温度升高来促进米粒吸水。Specifically, in the pre-processing stage, the heating device may be controlled to perform heating work so that the temperature in the cooking cavity is gradually increased, and when the temperature in the cooking cavity reaches a first temperature value, the heating and boiling phase is entered. Alternatively, during the pre-processing phase, the running time of the pre-processing phase is recorded, and the heating device is controlled to perform the heating work so that the temperature in the cooking cavity is maintained at a preset water absorption temperature, such as 55 ° C, so that the rice grains fully absorb water. When the time reaches the preset water absorption time, for example, 10 minutes, the heating device is controlled to perform the heating operation so that the temperature in the cooking cavity continues to rise, and when the temperature in the cooking cavity reaches the first temperature value, the heating and boiling phase is entered (as shown in FIG. 4). Temperature curve). Also, in the pre-processing stage, the vacuum device can be controlled to evacuate to reduce the pressure in the cooking cavity (as shown in the pressure change curve in FIG. 4), so that the rice grains are more likely to absorb water, or the vacuum device can be controlled not to perform vacuum Vacuum, that is, does not reduce the pressure in the cooking cavity, uses the temperature increase to promote the rice grains to absorb water.
在升温沸腾阶段,通过控制加热装置可以使烹饪腔内的温度从第一温度值开始上升至第二温度值,并且控制真空装置对烹饪腔进行抽真空以使烹饪腔内形成负压真空,烹饪腔在较低温度即大米糊化但未粘结成团前时产生沸腾气泡,从而确保米粒不结块,保持松散透热。其中,烹饪腔内米水不断沸腾产生大量的蒸汽,使烹饪腔内的压力无法维持在低气压而逐渐上升。In the heating and boiling phase, the temperature in the cooking cavity can be raised from the first temperature value to the second temperature value by controlling the heating device, and the vacuum device is controlled to evacuate the cooking cavity to form a negative pressure vacuum in the cooking cavity. The cavity generates boiling air bubbles at a lower temperature, that is, before the rice is gelatinized but not bonded into a mass, thereby ensuring that the rice grains do not agglomerate and keep loose heat. Among them, the rice water in the cooking cavity is constantly boiling to generate a large amount of steam, so that the pressure in the cooking cavity cannot be maintained at a low air pressure and gradually rises.
并且,在烹饪腔内的压力大于或等于预设关闭压力或烹饪腔内的压力在预设采样时间内上升速率小于预设压力上升速率时,控制真空装置关闭,并根据控制烹饪器具的状态控制泄压装置对烹饪腔进行泄气,使烹饪器具恢复到常压状态,迁移到高温沸腾阶段。In addition, when the pressure in the cooking cavity is greater than or equal to a preset closing pressure or the pressure in the cooking cavity rises within a preset sampling time and is less than a preset pressure rise rate, the vacuum device is controlled to be turned off and controlled according to the state of the control cooking appliance The pressure relief device deflate the cooking cavity, restore the cooking utensil to a normal pressure state, and migrate to a high-temperature boiling stage.
在高温沸腾阶段,由于沸腾的气孔和通道已经形成,不需要抽真空降低烹饪腔内的压力,可控制真空装置一直处于关闭状态,并且通过控制加热装置以第一功率进行加热,以使加热装置维持在预设沸腾温度,例如大气压沸点附近的温度或者高于98℃的温度,从而,烹饪腔内的米水维持高温沸腾状态,确保将米饭煮熟。并且,在高温沸腾阶段的运行时间达到预设高温沸腾时间之后,进入焖饭阶段。In the high-temperature boiling stage, since the boiling pores and channels have been formed, there is no need to evacuate to reduce the pressure in the cooking cavity. The vacuum device can be controlled to be always closed, and the heating device can be heated at the first power to control the heating device. Maintaining a preset boiling temperature, such as a temperature near the boiling point of atmospheric pressure or a temperature higher than 98 ° C, so that the rice water in the cooking cavity maintains a high-temperature boiling state to ensure that the rice is cooked. In addition, after the operating time of the high-temperature boiling stage reaches a preset high-temperature boiling time, it enters a rice cooking stage.
在焖饭阶段,同样不需要抽真空降低烹饪腔内的压力,可控制真空装置一直处于关闭状态,并且通过控制加热装置以第二功率进行加热,以使加热装置维持在预设焖饭温度,例如大于第一温度值且小于第二温度值,从而,使米饭的香味和甜味更充足。其中,第二功率小于第一功率。In the rice cooking phase, it is also unnecessary to evacuate to reduce the pressure in the cooking cavity. The vacuum device can be controlled to be always turned off, and the heating device is controlled to be heated at a second power to maintain the heating device at a preset rice cooking temperature. For example, it is larger than the first temperature value and smaller than the second temperature value, so that the aroma and sweetness of the rice are more sufficient. The second power is smaller than the first power.

如上所述,如图4所示,本申请实施例的烹饪器具的烹饪过程可包括预处理阶段、升温沸腾阶段、高温沸腾阶段和焖饭阶段。As described above, as shown in FIG. 4, the cooking process of the cooking appliance according to the embodiment of the present application may include a pretreatment stage, a temperature-boiling stage, a high-temperature boiling stage, and a rice cooking stage.
具体地,在预处理阶段,可控制加热装置进行加热工作以使烹饪腔内的温度逐渐升高,当烹饪腔内的温度达到第一温度值时进入升温沸腾阶段。或者,在预处理阶段,记录预处理阶段的运行时间,并控制加热装置进行加热工作以使烹饪腔内的温度维持在预设吸水温度例如55℃以使米粒充分吸水,在预处理阶段的运行时间达到预设吸水时间例如10分钟时,控制加热装置进行加热工作以使烹饪腔内的温度继续升高,当烹饪腔内的温度达到第一温度值时进入升温沸腾阶段(如图4中的温度变化曲线)。并且,在预处理阶段,可控制真空装置进行抽真空,以降低烹饪腔内的压力(如图4中的压力变化曲线),使米粒更多容易吸水,或者,也可控制真空装置不进行抽真空,即不降低烹饪腔内的压力,利用温度升高来促进米粒吸水。Specifically, in the pre-processing stage, the heating device may be controlled to perform heating work so that the temperature in the cooking cavity is gradually increased, and when the temperature in the cooking cavity reaches a first temperature value, the heating and boiling phase is entered. Alternatively, during the pre-processing phase, the running time of the pre-processing phase is recorded, and the heating device is controlled to perform the heating work so that the temperature in the cooking cavity is maintained at a preset water absorption temperature, such as 55 ° C, so that the rice grains fully absorb water. When the time reaches the preset water absorption time, for example, 10 minutes, the heating device is controlled to perform the heating operation so that the temperature in the cooking cavity continues to rise, and when the temperature in the cooking cavity reaches the first temperature value, the heating and boiling phase is entered (as shown in FIG. 4). Temperature curve). Also, in the pre-processing stage, the vacuum device can be controlled to evacuate to reduce the pressure in the cooking cavity (as shown in the pressure change curve in FIG. 4), so that the rice grains are more likely to absorb water, or the vacuum device can be controlled not to perform vacuum Vacuum, that is, does not reduce the pressure in the cooking cavity, uses the temperature increase to promote the rice grains to absorb water.
在升温沸腾阶段,通过控制加热装置可以使烹饪腔内的温度从第一温度值开始上升至第二温度值,并且控制真空装置对烹饪腔进行抽真空以使烹饪腔内形成负压真空,烹饪腔在较低温度即大米糊化但未粘结成团前时产生沸腾气泡,从而确保米粒不结块,保持松散透热。其中,烹饪腔内米水不断沸腾产生大量的蒸汽,使烹饪腔内的压力无法维持在低气压而逐渐上升。In the heating and boiling phase, the temperature in the cooking cavity can be raised from the first temperature value to the second temperature value by controlling the heating device, and the vacuum device is controlled to evacuate the cooking cavity to form a negative pressure vacuum in the cooking cavity. The cavity generates boiling air bubbles at a lower temperature, that is, before the rice is gelatinized but not bonded into a mass, thereby ensuring that the rice grains do not agglomerate and keep loose heat. Among them, the rice water in the cooking cavity is constantly boiling to generate a large amount of steam, so that the pressure in the cooking cavity cannot be maintained at a low air pressure and gradually rises.
并且,根据烹饪腔内的温度、烹饪腔内的压力和升温沸腾阶段的运行时间中至少两个控制真空装置关闭,并根据控制烹饪器具的状态控制泄压装置对烹饪腔进行泄气,使烹饪器具恢复到常压状态,迁移到高温沸腾阶段。In addition, according to the temperature in the cooking cavity, the pressure in the cooking cavity, and the operating time of the heating and boiling phase, at least two control vacuum devices are turned off, and the pressure relief device is controlled to degas the cooking cavity according to the state of the control cooking appliance, so that the cooking appliance Return to normal pressure and migrate to high temperature boiling stage.
在高温沸腾阶段,由于沸腾的气孔和通道已经形成,不需要抽真空降低烹饪腔内的压力,可控制真空装置一直处于关闭状态,并且通过控制加热装置以第一功率进行加热,以使加热装置维持在预设沸腾温度,例如大气压沸点附近的温度或者高于98℃的温度,从而,烹饪腔内的米水维持高温沸腾状态,确保将米饭煮熟。并且,在高温沸腾阶段的运行时间达到预设高温沸腾时间之后,进入焖饭阶段。In the high-temperature boiling stage, since the boiling pores and channels have been formed, there is no need to evacuate to reduce the pressure in the cooking cavity. The vacuum device can be controlled to be always closed, and the heating device can be heated at the first power to control the heating device. Maintaining a preset boiling temperature, such as a temperature near the boiling point of atmospheric pressure or a temperature higher than 98 ° C, so that the rice water in the cooking cavity maintains a high-temperature boiling state to ensure that the rice is cooked. In addition, after the operating time of the high-temperature boiling stage reaches a preset high-temperature boiling time, it enters a rice cooking stage.
在焖饭阶段,同样不需要抽真空降低烹饪腔内的压力,可控制真空装置一直处于关闭状态,并且通过控制加热装置以第二功率进行加热,以使加热装置维持在预设焖饭温度,例如大于第一温度值且小于第二温度值,从而,使米饭的香味和甜味更充足。其中,第二功率小于第一功率。In the rice cooking phase, it is also unnecessary to evacuate to reduce the pressure in the cooking cavity. The vacuum device can be controlled to be always turned off, and the heating device is controlled to be heated at a second power to maintain the heating device at a preset rice cooking temperature. For example, it is larger than the first temperature value and smaller than the second temperature value, so that the aroma and sweetness of the rice are more sufficient. The second power is smaller than the first power.

在前述实施例中,根据升温沸腾阶段的运行时间控制真空装置关闭之后,真空装置将不再开启直至烹饪结束,即真空装置在后续的高温沸腾阶段和焖饭装置也将保持关闭。In the foregoing embodiment, after the vacuum device is turned off according to the operating time of the heating and boiling phase, the vacuum device will not be turned on until the end of cooking, that is, the vacuum device will remain closed in the subsequent high-temperature boiling phase and the rice cooker.
下面通过四个实施例来详细说明升温沸腾阶段真空装置的具体控制方式。In the following, the specific control methods of the vacuum device in the heating and boiling phase are described in detail through four embodiments.
实施例一:Embodiment one:
根据本申请的一个实施例,当烹饪器具处于升温沸腾阶段时,控制真空装置对烹饪腔进行至少一次抽真空,以使烹饪腔在烹饪腔内的温度达到第一温度值或大于第一温度值预设阈值时产生沸腾气泡。According to an embodiment of the present application, when the cooking appliance is in a temperature-boiling stage, the control vacuum device vacuums the cooking cavity at least once, so that the temperature of the cooking cavity in the cooking cavity reaches a first temperature value or greater than the first temperature value. Boiling bubbles occur at a preset threshold.
可理解,当烹饪腔内的温度达到第一温度值例如55℃时,米粒处于即将糊化的阶段,此时,可控制真空装置对烹饪腔进行至少一次抽真空,使烹饪腔内形成负压,根据气压与沸点的对应可知,烹饪腔内的气压降低,米水沸点随之降低,由此,通过抽真空,米水可在较低温度(大米糊化但未粘结成团前)产生沸腾气泡,形成密集气泡通道,气泡扰动使米粒松散不黏结,强化对流传热,进而提升米粒的受热均匀性,最终提升米饭的品质。Understandably, when the temperature in the cooking cavity reaches a first temperature value, for example, 55 ° C., the rice grains are about to be gelatinized. At this time, the vacuum device can be controlled to vacuum the cooking cavity at least once, so that a negative pressure is formed in the cooking cavity. According to the correspondence between the air pressure and the boiling point, it can be known that the air pressure in the cooking cavity decreases, and the boiling point of the rice water decreases. Therefore, by evacuating the rice water, the rice water can be produced at a lower temperature (before the rice gelatinizes but does not stick into a mass). Boiling air bubbles, forming dense air bubble channels, the disturbance of the air bubbles makes the rice grains loose and non-sticky, and enhances the convective heat transfer, thereby improving the heating uniformity of the rice grains and ultimately improving the quality of the rice.
其中,沸腾气泡的数量与烹饪腔内的压力呈反比,沸腾气泡的产生时间与烹饪腔内的压力呈正比。即言,烹饪腔内的压力越大,气泡脱离所需的体积越大,沸腾气泡的数量越少,产生时间越长。Among them, the number of boiling bubbles is inversely proportional to the pressure in the cooking cavity, and the generation time of the boiling bubbles is proportional to the pressure in the cooking cavity. That is, the larger the pressure in the cooking cavity, the larger the volume required for the bubbles to detach, the less the number of boiling bubbles, and the longer the generation time.
进一步结合图11-14说明升温沸腾阶段通过抽真空以提升受热均匀性的工作原理。例如,如图11和图13所示,在升温沸腾阶段,如果未抽真空即烹饪腔处于常压,则米水在较高温度才会发生沸腾,即在温度为70℃时气泡核心生成,在温度为88℃时气泡脱离,在温度为98℃时稳定沸腾,由此可知,对于未抽真空的情况,米粒在沸腾气泡产生时已粘结成团即形成米团,阻碍热量对流,即在米团外部形成气泡通道,热量通过米团外部的气泡通道传递,使得热量的对流传递不充分,米饭受热不均匀(如图13所示)。又如,如图12 和图14所示,在升温沸腾阶段,通过抽真空使烹饪腔内形成负压,则米水在较低温度就会发生沸腾,即在温度为60℃时气泡核心生成,在温度为68℃时气泡脱离,在温度为80℃时稳定沸腾,由此可知,对于抽真空的情况,米粒在沸腾气泡产生时未粘结成团,气泡扰动使米粒松散不黏结,进而形成密集的气泡通道,即在松散的米粒之间形成气泡通道,热量通过米粒之间的气泡通道传递,能够强化对流传热,米饭受热均匀(如图14所示)。The working principle of increasing the heating uniformity by evacuation during the heating and boiling phase is further described with reference to FIGS. 11-14. For example, as shown in Figures 11 and 13, during the temperature-boiling phase, if the cooking cavity is at normal pressure without vacuuming, the rice water will boil at a higher temperature, that is, the core of the bubble is generated at a temperature of 70 ° C. When the temperature is 88 ° C, the bubbles are detached, and when the temperature is 98 ° C, the boiling is stable. From this, it can be known that for the case without vacuum, the rice grains have formed a mass when the boiling bubbles are generated, which hinders the convection of heat, that is, A bubble channel is formed outside the rice ball, and heat is transferred through the bubble channel outside the rice ball, so that the convective transfer of heat is insufficient, and the rice is unevenly heated (as shown in Figure 13). As another example, as shown in Figures 12 and 14, during the heating and boiling phase, a negative pressure is formed in the cooking cavity by evacuating, and the rice water will boil at a lower temperature, that is, the bubble core is generated at a temperature of 60 ° C. When the temperature is 68 ° C, the bubbles are detached, and the temperature is stable when the temperature is 80 ° C. From this, it can be known that for the case of vacuuming, the rice grains are not bound into agglomerates when the boiling bubbles are generated, and the bubble disturbance makes the rice grains loose and not stick, and then Form dense bubble channels, that is, bubble channels are formed between loose rice grains, and heat is transferred through the bubble channels between rice grains, which can enhance convective heat transfer, and the rice is evenly heated (as shown in Figure 14).
需要说明的是,本申请实施例中的“负压”是指低于大气压的压力。例如,当外部大气压为101kPa时,烹饪腔内的压力为70kPa时即认为烹饪腔内形成负压。It should be noted that the “negative pressure” in the examples of the present application refers to a pressure lower than the atmospheric pressure. For example, when the external atmospheric pressure is 101 kPa and the pressure in the cooking cavity is 70 kPa, it is considered that a negative pressure is formed in the cooking cavity.
由此,本申请实施例的烹饪控制方法,在升温沸腾阶段,即从第一温度值开始至第二温度值的范围内,控制真空装置对烹饪腔进行至少一次抽真空以使烹饪腔内形成负压真空,使沸腾温度降至米粒未开始糊化或刚开始糊化的温度附近,即“低温沸腾”,烹饪腔在较低温度即大米糊化但未粘结成团前时产生沸腾气泡,从而确保米粒不结块,保持松散透热。Therefore, in the cooking control method of the embodiment of the present application, in the temperature-boiling stage, that is, from the first temperature value to the second temperature value, controlling the vacuum device to evacuate the cooking cavity at least once to form the cooking cavity. Negative pressure vacuum reduces the boiling temperature to near the temperature at which the rice grains do not begin to gelatinize or just begin to gelatinize, that is, "low temperature boiling". The cooking cavity generates boiling bubbles at a lower temperature, that is, when the rice gelatinizes but does not stick together So as to ensure that the rice grains are not agglomerated and keep loose and permeable.
根据本申请的一个具体实施例,控制真空装置对烹饪腔进行至少一次抽真空可包括,控制真空装置对烹饪腔进行至少一次连续抽真空或间歇抽真空。换言之,在升温沸腾阶段,可以控制真空装置持续开启一定时间,或者,可以控制真空装置间歇地开启。例如,可通过真空装置抽真空N(N为大于等于1的整数)次,每次抽真空时,可控制真空装置持续进行工作,真空泵一直转动,或者,可控制真空装置以开启to时间和关闭tc时间的方式间歇地进行工作,即真空泵以转动to停止tc的方式运转。According to a specific embodiment of the present application, controlling the vacuum device to evacuate the cooking cavity at least once may include: controlling the vacuum device to evacuate the cooking cavity at least once continuously or intermittently. In other words, during the heating and boiling phase, the vacuum device can be controlled to be continuously turned on for a certain time, or the vacuum device can be controlled to be intermittently turned on. For example, the vacuum device can be used to evacuate N (N is an integer greater than or equal to 1) times. Each time the vacuum is evacuated, the vacuum device can be controlled to continue to work, and the vacuum pump is always rotating. Or, the vacuum device can be controlled to turn on and off. The tc time mode works intermittently, that is, the vacuum pump rotates to stop tc.
实施例二:Embodiment two:
根据本申请的一个实施例,当烹饪器具进入升温沸腾阶段时,控制加热装置进行加热工作,同时控制真空装置对烹饪腔进行抽真空,以使烹饪腔产生沸腾气泡。According to an embodiment of the present application, when the cooking appliance enters a heating and boiling phase, the heating device is controlled to perform heating work, and at the same time, the vacuum device is controlled to evacuate the cooking cavity to generate boiling bubbles in the cooking cavity.
本申请实施例的烹饪控制方法,在升温沸腾阶段,即从第一温度值开始至第二温度值的范围内,控制真空装置对烹饪腔进行抽真空以使烹饪腔内形成负压真空,使沸腾温度降至米粒未开始糊化或刚开始糊化的温度附近,即“低温沸腾”,利用沸腾所产生的脱离气泡对米粒形成扰动,米粒在扰动情况下相互间互不粘连,避免了结块,使米粒更均匀的受热。In the cooking control method of the embodiment of the present application, in the temperature-boiling stage, that is, from the first temperature value to the second temperature value, controlling the vacuum device to evacuate the cooking cavity to form a negative pressure vacuum in the cooking cavity, so that The boiling temperature is lowered to the temperature where the rice grains have not started to gelatinize or have just started to gelatinize, that is, "low temperature boiling".

To make rice grains more uniformly heated.
具体地,在进入升温沸腾阶段时,控制加热装置进行加热工作以使提高烹饪腔内的温度,同时控制真空装置对烹饪腔进行抽真空以降低烹饪腔内的压力,即同时进行加热和抽真空。通过大量实验和理论分析得出,在加热升温的同时进行抽真空,更能促进水中饱和气体的析出,形成细小的气泡不断向烹饪腔内米水的表面涌出,使米粒受到一定的扰动,更好地避免米粒粘结。Specifically, when the heating and boiling phase is entered, the heating device is controlled to perform heating work so as to increase the temperature in the cooking cavity, and at the same time, the vacuum device is controlled to evacuate the cooking cavity to reduce the pressure in the cooking cavity, that is, to perform heating and vacuum simultaneously. . Through a large number of experiments and theoretical analysis, it is concluded that vacuuming at the same time of heating can promote the precipitation of saturated gas in the water, and form fine bubbles to continuously pour out on the surface of rice water in the cooking cavity, causing the rice grains to be disturbed to a certain degree. Better avoid rice grains sticking.
可以理解的是,“同时进行加热和抽真空”可以是指,加热装置和真空装置存在一段时 间是同时启动的。例如,在进入升温沸腾阶段时可控制加热装置启动以对烹饪腔进行加热,其中,真空装置可与加热装置同时启动,即在进入升温沸腾阶段时同时控制真空装置启动以对烹饪腔进行抽真空,但真空装置与加热装置可同时关闭,也可不同时关闭,即加热装置先关闭真空装置后关闭或真空装置先关闭加热装置后关闭。It can be understood that "simultaneously heating and evacuation" may mean that the heating device and the vacuum device are activated simultaneously for a period of time. For example, when the heating and boiling phase is entered, the heating device can be controlled to start to heat the cooking cavity, wherein the vacuum device can be started at the same time as the heating device, that is, when the heating and boiling phase is entered, the vacuum device is controlled to be started to evacuate the cooking cavity at the same time. However, the vacuum device and the heating device can be turned off at the same time, or they can not be turned off at the same time, that is, the heating device is turned off first and then the vacuum device is turned off or the vacuum device is turned off first and then the heating device is turned off.
根据本申请的一个具体实施例,加热装置进行加热同时真空装置进行抽真空的时间可持续预设时间t0,其中,预设时间为0-20min,即0<t0<20min,以确保低温沸腾的效果。可以理解的是,如果低温沸腾的时间过短,则沸腾不充分,无法更好地避免米粒粘结,如果低温沸腾的时间过长,则导致烹饪时间过长,影响用户的体验。本申请实施例,通过将同时进行加热和抽真空的时间设置为0<t0<20min,可以确保低温沸腾的效果。According to a specific embodiment of the present application, the heating device performs heating and the vacuum device performs vacuum for a preset time t0, wherein the preset time is 0-20min, that is, 0 <t0 <20min, to ensure low temperature boiling. effect. It can be understood that if the low-temperature boiling time is too short, the boiling is insufficient, and the rice grains cannot be better avoided; if the low-temperature boiling time is too long, the cooking time is too long, which affects the user experience. In the embodiment of the present application, by setting the time for simultaneously heating and evacuating to 0 <t0 <20min, the effect of low temperature boiling can be ensured.
进一步地,根据本申请的一些实施例,当加热装置进行加热同时真空装置进行抽真空的时间达到预设时间时,控制加热装置间隔地进行加热工作或连续地进行加热工作,和/或控制真空装置间隔地进行抽真空或连续地进行抽真空。其中,预设时间可为0-20min。Further, according to some embodiments of the present application, when the heating device performs heating and the vacuum device performs the evacuation time to a preset time, the heating device is controlled to perform the heating operation at intervals or continuously, and / or the vacuum is controlled.

也就是说,在同时加热和抽真空时间段之后,可控制加热装置继续进行加热或者不进行加热,并且可控制真空装置继续进行抽真空或者不进行抽真空。其中,加热装置和真空装置是否继续进行工作可根据烹饪过程的实际需求确定。例如,可根据升温速度需求控制加热装置间隔地进行加热工作或连续地进行加热工作;而真空装置也可以根据烹饪腔内的压力间隔地进行抽真空或连续地进行抽真空。In other words, after the heating and vacuuming period, the heating device may be controlled to continue heating or not to be heated, and the vacuum device may be controlled to continue to be vacuumed or not to be vacuumed. Among them, whether the heating device and the vacuum device continue to work can be determined according to the actual needs of the cooking process. For example, the heating device may be controlled to perform the heating operation at intervals or continuously according to the requirement of the heating rate; and the vacuum device may also perform the vacuum at intervals or continuously to perform the vacuum according to the pressure in the cooking cavity.
具体地,根据本申请的一个实施例,控制加热装置间隔地进行加热工作或连续地进行加热工作包括:Specifically, according to an embodiment of the present application, controlling the heating device to perform heating work at intervals or continuously includes:

需要说明的是,升温速度可通过试验得到,并在出厂时预先设定。It should be noted that the heating rate can be obtained through experiments and is preset in the factory.
举例来说,在同时加热和抽真空时间段之后,可实时获取烹饪腔内的温度,并确定烹饪腔内的温度在预设采样时间内的变化率,当烹饪腔内的温度在预设采样时间内的变化率大于或等于预设的升温速度,控制加热装置停止进行加热工作,当烹饪腔内的温度在预设采样时间内的变化率小于预设的升温速度,控制加热装置间隔地进行加热工作或连续地进行加热工作,从而确保烹饪腔内的温度按照预设的升温速度逐渐升高。For example, after the simultaneous heating and vacuuming periods, the temperature in the cooking cavity can be obtained in real time, and the rate of change of the temperature in the cooking cavity within a preset sampling time can be determined. The rate of change within time is greater than or equal to the preset heating rate, and the heating device is controlled to stop heating. When the rate of change of the temperature in the cooking cavity within the preset sampling time is less than the preset heating rate, the heating device is controlled to be performed at intervals. The heating operation or the continuous heating operation is performed to ensure that the temperature in the cooking cavity gradually increases according to a preset heating rate.

When the pressure in the cooking cavity is greater than a preset pressure, the vacuum device is controlled to perform evacuation at intervals or continuously. The pressure in the cooking cavity is less than or equal to a preset heating rate, and the vacuum device is controlled to stop vacuuming, thereby ensuring that the vacuum in the cooking cavity is maintained at the preset pressure.
如上所述,如图15所示,本申请实施例的烹饪器具的烹饪过程可包括预处理阶段A1、升温沸腾阶段A2、高温沸腾阶段A3和焖饭阶段A4。As described above, as shown in FIG. 15, the cooking process of the cooking appliance according to the embodiment of the present application may include a pre-treatment phase A1, a temperature-boiling phase A2, a high-temperature boiling phase A3, and a rice cooking phase A4.
具体地,在预处理阶段A1,可控制加热装置进行加热工作以使烹饪腔内的温度逐渐升高(如图15中的曲线X1),当烹饪腔内的温度达到第一温度值T1时进入升温沸腾阶段。或者,在预处理阶段A1,记录预处理阶段的运行时间,并控制加热装置进行加热工作以使烹饪腔内的温度维持在预设吸水温度例如55℃以使米粒充分吸水,在预处理阶段的运行时间达到预设吸水时间例如10分钟时,控制加热装置进行加热工作以使烹饪腔内的温度继续升高,当烹饪腔内的温度达到第一温度值时进入升温沸腾阶段。并且,在预处理阶段A1,可控制真空装置进行抽真空,以降低烹饪腔内的压力(如图15中的曲线X2),使米粒更容易吸水,或者,也可控制真空装置不进行抽真空,即不降低烹饪腔内的压力,利用温度升高来促进米粒吸水。Specifically, in the pre-processing stage A1, the heating device may be controlled to perform heating work to gradually increase the temperature in the cooking cavity (such as the curve X1 in FIG. 15), and enter when the temperature in the cooking cavity reaches the first temperature value T1. Boiling stage. Alternatively, in the pre-processing phase A1, the running time of the pre-processing phase is recorded, and the heating device is controlled to perform the heating work so that the temperature in the cooking cavity is maintained at a preset water absorption temperature, such as 55 ° C. to allow the rice grains to fully absorb water. When the running time reaches a preset water absorption time, for example, 10 minutes, the heating device is controlled to perform heating work so that the temperature in the cooking cavity continues to rise, and when the temperature in the cooking cavity reaches the first temperature value, the heating and boiling phase is entered. In addition, in the pre-processing stage A1, the vacuum device can be controlled to evacuate to reduce the pressure in the cooking cavity (such as the curve X2 in FIG. 15), so that the rice grains can more easily absorb water, or the vacuum device can be controlled not to perform vacuum That is, without reducing the pressure in the cooking cavity, the temperature increase is used to promote the water absorption of the rice grains.
需要说明的是,在预处理阶段进行抽真空,以使烹饪腔内的压力达到预设吸水压力之后,可不再抽真空,烹饪腔内的压力将逐渐升高,或者,在预处理阶段进行抽真空,可以使烹饪腔内的压力达到预设吸水压力之后,继续抽真空以使烹饪腔内的压力维持在于预设吸水压力,其中,预设吸水压力小于标准大气压。It should be noted that after the vacuum is pre-processed so that the pressure in the cooking chamber reaches a preset suction pressure, the vacuum may no longer be evacuated, and the pressure in the cooking chamber will gradually increase. With vacuum, after the pressure in the cooking cavity reaches a preset suction pressure, the vacuum is continued to be maintained to maintain the pressure in the cooking cavity at the preset suction pressure, wherein the preset suction pressure is less than the standard atmospheric pressure.
在升温沸腾阶段A2,控制加热装置进行加热工作即加热装置处于“on”状态,同时控制真空装置进行抽真空即真空装置处于“on”状态,同时进行加热和抽真空的时间可持续预设时间t0。在预设时间t0后,可根据升温速度需求控制加热装置间隔地进行加热工作或连续地进行加热工作;而真空装置可不再开启,烹饪腔内的压力逐渐升高,或者,真空装置也可以根据烹饪腔内的压力间隔地进行抽真空或连续地进行抽真空,烹饪腔内的压力维持在预设压力。In the heating and boiling phase A2, the heating device is controlled to perform the heating operation, that is, the heating device is in the "on" state, and the vacuum device is controlled to perform the vacuum, that is, the vacuum device is in the "on" state. t0. After the preset time t0, the heating device can be controlled to perform the heating operation at intervals or continuously according to the heating speed requirement; while the vacuum device can no longer be turned on and the pressure in the cooking cavity gradually increases, or the vacuum device can also be adjusted according to The pressure in the cooking cavity is evacuated at intervals or continuously, and the pressure in the cooking cavity is maintained at a preset pressure.
在整个升温沸腾阶段A2,通过控制加热装置可以使烹饪腔内的温度从第一温度值T1 开始上升至第二温度值T2,并且控制真空装置对烹饪腔进行抽真空以使烹饪腔内形成负压真空,烹饪腔在较低温度即大米糊化但未粘结成团前时产生沸腾气泡,从而确保米粒不结块,保持松散透热。并且,在烹饪器具的状态参数满足预设条件时控制真空装置关闭并控制压装置对烹饪腔进行泄气,使烹饪器具恢复到常压状态,迁移到高温沸腾阶段A3。Throughout the heating and boiling phase A2, the temperature in the cooking cavity can be increased from the first temperature value T1 to the second temperature value T2 by controlling the heating device, and the vacuum device is controlled to evacuate the cooking cavity to make the cooking cavity negative. Pressing the vacuum, the cooking cavity generates boiling bubbles at a lower temperature, that is, when the rice is gelatinized but not adhered to a mass, thereby ensuring that the rice grains do not agglomerate and keep loose heat. In addition, when the state parameters of the cooking appliance meet a preset condition, the vacuum device is controlled to be closed and the pressure device is controlled to deflate the cooking cavity to return the cooking appliance to a normal pressure state and migrate to the high-temperature boiling stage A3.
在高温沸腾阶段A3,由于沸腾的气孔和通道已经形成,不需要抽真空降低烹饪腔内的压力,可控制真空装置一直处于关闭状态,并且通过控制加热装置以第一功率进行加热,以使加热装置维持在预设沸腾温度,例如大气压沸点附近的温度或者高于98℃的温度,从而,烹饪腔内的米水维持高温沸腾状态,确保将米饭煮熟。并且,在高温沸腾阶段A3的运行时间达到预设高温沸腾时间之后,进入焖饭阶段A4。In the high-temperature boiling stage A3, because the boiling pores and channels have been formed, no vacuum is required to reduce the pressure in the cooking cavity. The vacuum device can be controlled to be always closed, and the heating device is controlled to heat at the first power to make the heating The device maintains a preset boiling temperature, such as a temperature near the boiling point of atmospheric pressure or a temperature higher than 98 ° C, so that the rice water in the cooking cavity maintains a high-temperature boiling state, ensuring that the rice is cooked. In addition, after the running time of the high-temperature boiling stage A3 reaches the preset high-temperature boiling time, the process proceeds to the rice-cooking stage A4.
在焖饭阶段A4,同样不需要抽真空降低烹饪腔内的压力,可控制真空装置一直处于关闭状态,并且通过控制加热装置以第二功率进行加热,以使加热装置维持在预设焖饭温度,例如预设焖饭温度大于第一温度值且小于第二温度值,从而,使米饭的香味和甜味更充足。其中,第二功率小于第一功率。In the rice cooking stage A4, there is also no need to evacuate to reduce the pressure in the cooking cavity. The vacuum device can be controlled to be always turned off, and the heating device is controlled to be heated at the second power to maintain the heating device at a preset rice cooking temperature. For example, the preset rice temperature is greater than the first temperature value and less than the second temperature value, so that the aroma and sweetness of the rice are more sufficient. The second power is smaller than the first power.

实施例三:Embodiment three:
根据本申请的一个实施例,当烹饪器具进入升温沸腾阶段时,先控制真空装置对烹饪腔进行抽真空,再控制加热装置进行加热工作,以使烹饪腔产生沸腾气泡。According to an embodiment of the present application, when the cooking appliance enters a heating and boiling stage, the vacuum device is first controlled to evacuate the cooking cavity, and then the heating device is controlled to perform heating work so that the cooking cavity generates boiling bubbles.
本申请实施例的烹饪控制方法,在升温沸腾阶段,即从第一温度值开始至第二温度值的范围内,控制真空装置对烹饪腔进行抽真空以使烹饪腔内形成负压真空,使沸腾温度降至米粒未开始糊化或刚开始糊化的温度附近,即“低温沸腾”,利用沸腾所产生的脱离气泡 对米粒形成扰动,米粒在扰动情况下相互间互不粘连,避免了结块,使米粒更均匀的受热。In the cooking control method of the embodiment of the present application, in the temperature-boiling stage, that is, from the first temperature value to the second temperature value, controlling the vacuum device to evacuate the cooking cavity to form a negative pressure vacuum in the cooking cavity, so that The boiling temperature is lowered to the temperature where the rice grains have not started to gelatinize or have just started to gelatinize, that is, "low temperature boiling". The detached air bubbles generated by boiling disturb the rice grains, and the rice grains do not stick to each other under the disturbance to avoid agglomeration. To make rice grains more uniformly heated.
具体地,在进入升温沸腾阶段时,先控制真空装置对烹饪腔进行抽真空以降低烹饪腔内的压力,再控制加热装置进行加热工作以使提高烹饪腔内的温度,即先进行抽真空再进行加热。通过大量实验和理论分析得出,在加热沸腾阶段,由于温度已经大于米粒的糊化温度,如果烹饪器具的底部快速进行加热会导致底部米粒由于过热而表面产生严重糊化,结块加剧,因此可先抽真空使烹饪腔内的压力快速降低,使水中气体和底部气泡核心只要吸收少量热量就能达到脱离和平衡不破的初始状态,再进行加热,这样更好确保底部米粒在未形成过度糊化前底部已形成大量的气泡脱离,米粒受气泡脱离产生的扰动影响而不粘结,最终使米饭受热均匀。Specifically, when the heating and boiling phase is entered, the vacuum device is first controlled to evacuate the cooking cavity to reduce the pressure in the cooking cavity, and then the heating device is controlled to perform the heating work to increase the temperature in the cooking cavity, that is, the vacuum is first evacuated and then Heat. Through a large number of experiments and theoretical analysis, it is found that during the heating and boiling stage, because the temperature is already higher than the gelatinization temperature of the rice grains, if the bottom of the cooking utensil is heated quickly, the surface of the bottom rice grains will be seriously gelatinized due to overheating, and the agglomeration will increase. Vacuum can be used to quickly reduce the pressure in the cooking cavity, so that the gas in the water and the bottom bubble core can absorb the small amount of heat to reach the initial state of detachment and balance. Then, the heating is performed to better ensure that the bottom rice grains do not form excessive paste. A large number of air bubbles have formed at the bottom before the rice is detached, and the rice grains are not affected by the disturbance caused by the air bubbles, and the rice is finally heated uniformly.
根据本申请的一个具体实施例,真空装置进行抽真空的时间可持续预设时间t1,其中,预设抽真空时间为0-20min,即0<t1<20min,以确保低温沸腾的效果。可以理解的是,如果低温沸腾的时间过短,则沸腾不充分,无法更好地避免米粒粘结,如果低温沸腾的时间过长,则导致烹饪时间过长,影响用户的体验。本申请实施例,通过将抽真空的时间设置为0<t1<20min,可以确保低温沸腾的效果。其中,预设抽真空时间优选为1min。According to a specific embodiment of the present application, the vacuum device can be evacuated for a preset time t1, wherein the preset vacuum time is 0-20min, that is, 0 <t1 <20min, to ensure the effect of low temperature boiling. It can be understood that if the low-temperature boiling time is too short, the boiling is insufficient, and the rice grains cannot be better avoided; if the low-temperature boiling time is too long, the cooking time is too long, which affects the user experience. In the embodiment of the present application, by setting the evacuation time to 0 <t1 <20min, the effect of low temperature boiling can be ensured. The preset evacuation time is preferably 1 min.
进一步地,根据本申请的一些实施例,先控制真空装置对烹饪腔进行抽真空再控制加热装置进行加热工作包括:当真空装置进行抽真空的时间达到预设抽真空时间时,控制加热装置进行加热工作,例如控制加热装置间隔地进行加热工作或连续地进行加热工作。其中,预设抽真空时间可为0-20min。Further, according to some embodiments of the present application, first controlling the vacuum device to evacuate the cooking cavity and then controlling the heating device to perform the heating work includes: controlling the heating device to perform when the vacuum device's vacuuming time reaches a preset vacuuming time The heating operation, for example, controls the heating device to perform the heating operation at intervals or continuously. The preset evacuation time can be 0-20min.
也就是说,对于先抽真空后加热,可先控制真空装置进行抽真空以使烹饪腔内的压力降低,抽真空预设时间后,再控制加热装置进行加热,以使烹饪腔内产生沸腾。这样更好确保底部米粒在未形成过度糊化前底部已形成大量的气泡脱离,米粒受气泡脱离产生的扰动影响而不粘结,最终使米饭受热均匀。In other words, for vacuuming and heating first, the vacuum device can be controlled to reduce the pressure in the cooking cavity. After a preset time of vacuuming, the heating device can be controlled to heat to cause boiling in the cooking cavity. In this way, it is better to ensure that a large number of air bubbles are formed at the bottom of the bottom rice grains before the excessive gelatinization is formed. The rice grains are not affected by the disturbance caused by the air bubble separation, and the rice is uniformly heated.

也就是说,在先抽真空后可再同时加热和抽真空。可以理解的是,“同时进行加热和抽真空”可以是指,加热装置和真空装置存在一段时间是同时启动的。例如,在控制真空装置进行抽真空的时间达到预设抽真空时间后,可控制加热装置启动以对烹饪腔进行加热, 此时,真空装置可在加热过程中的任一时刻启动,例如即在加热装置启动的同时控制真空装置启动以对烹饪腔进行抽真空,或者,在加热装置启动一段时间后再控制真空装置启动。而且,真空装置与加热装置可同时关闭,也可不同时关闭,即加热装置先关闭真空装置后关闭或真空装置先关闭加热装置后关闭。That is, heating and evacuation can be performed simultaneously after evacuation. It can be understood that "simultaneously heating and vacuuming" can mean that the heating device and the vacuum device are activated simultaneously for a period of time.

Alternatively, in the pre-processing phase A1, the running time of the pre-processing phase is recorded, and the heating device is controlled to perform the heating work so that the temperature in the cooking cavity is maintained at a preset water absorption temperature, such as 55 ° C. to allow the rice grains to fully absorb water. When the running time reaches a preset water absorption time, for example, 10 minutes, the heating device is controlled to perform heating work so that the temperature in the cooking cavity continues to rise, and when the temperature in the cooking cavity reaches the first temperature value, the heating and boiling phase is entered. In addition, in the pre-processing stage A1, the vacuum device can be controlled to evacuate to reduce the pressure in the cooking cavity (as shown by curve Q2 in FIG. 18), so that the rice grains can absorb water more easily, or the vacuum device can be controlled not to perform vacuum That is, without reducing the pressure in the cooking cavity, the temperature increase is used to promote the water absorption of the rice grains.
需要说明的是,在预处理阶段进行抽真空,以使烹饪腔内的压力达到预设吸水压力之后,可不再抽真空,烹饪腔内的压力将逐渐升高,或者,在预处理阶段进行抽真空,可以使烹饪腔内的压力达到预设吸水压力之后,继续抽真空以使烹饪腔内的压力维持在于预设吸水压力,其中,预设吸水压力小于标准大气压。It should be noted that after the vacuum is pre-processed so that the pressure in the cooking chamber reaches a preset suction pressure, the vacuum may no longer be evacuated, and the pressure in the cooking chamber will gradually increase.

Pressing the vacuum, the cooking cavity generates boiling bubbles at a lower temperature, that is, when the rice is gelatinized but not adhered to a mass, thereby ensuring that the rice grains do not agglomerate and keep loose heat. In addition, when the state parameters of the cooking appliance meet a preset condition, the vacuum device is controlled to be closed and the pressure device is controlled to deflate the cooking cavity to return the cooking appliance to a normal pressure state and migrate to the high-temperature boiling stage A3.
在高温沸腾阶段A3,由于沸腾的气孔和通道已经形成,不需要抽真空降低烹饪腔内的压力,可控制真空装置一直处于关闭状态,并且通过控制加热装置以第一功率进行加热,以使加热装置维持在预设沸腾温度,例如大气压沸点附近的温度或者高于98℃的温度,从 而,烹饪腔内的米水维持高温沸腾状态,确保将米饭煮熟。并且,在高温沸腾阶段A3的运行时间达到预设高温沸腾时间之后,进入焖饭阶段A4。In the high-temperature boiling stage A3, because the boiling pores and channels have been formed, no vacuum is required to reduce the pressure in the cooking cavity. The vacuum device can be controlled to be always closed, and the heating device is controlled to heat at the first power to make the heating The device maintains a preset boiling temperature, such as a temperature near the boiling point of atmospheric pressure or a temperature higher than 98 ° C, so that the rice water in the cooking cavity maintains a high-temperature boiling state, ensuring that the rice is cooked. In addition, after the running time of the high-temperature boiling stage A3 reaches the preset high-temperature boiling time, the process proceeds to the rice-cooking stage A4.
在焖饭阶段A4,同样不需要抽真空降低烹饪腔内的压力,可控制真空装置一直处于关闭状态,并且通过控制加热装置以第二功率进行加热,以使加热装置维持在预设焖饭温度,例如预设焖饭温度大于第一温度值且小于第二温度值,从而,使米饭的香味和甜味更充足。其中,第二功率小于第一功率。In the rice cooking stage A4, there is also no need to evacuate to reduce the pressure in the cooking cavity. The vacuum device can be controlled to be always turned off, and the heating device is controlled to be heated at the second power to maintain the heating device at a preset rice cooking temperature. For example, the preset rice temperature is greater than the first temperature value and less than the second temperature value, so that the aroma and sweetness of the rice are more sufficient. The second power is smaller than the first power.

实施例四:Embodiment 4:
根据本申请的一个实施例,当烹饪器具进入升温沸腾阶段时,先控制加热装置进行加热工作,再控制真空装置对烹饪腔进行抽真空,以使烹饪腔产生沸腾气泡。According to an embodiment of the present application, when the cooking appliance enters a temperature-boiling stage, the heating device is first controlled to perform heating work, and then the vacuum device is controlled to evacuate the cooking cavity to generate boiling bubbles in the cooking cavity.
本申请实施例的烹饪控制方法,在升温沸腾阶段,即从第一温度值开始至第二温度值的范围内,控制真空装置对烹饪腔进行抽真空以使烹饪腔内形成负压真空,使沸腾温度降至米粒未开始糊化或刚开始糊化的温度附近,即“低温沸腾”,利用沸腾所产生的脱离气泡对米粒形成扰动,米粒在扰动情况下相互间互不粘连,避免了结块,使米粒更均匀的受热。In the cooking control method of the embodiment of the present application, in the temperature-boiling stage, that is, from the first temperature value to the second temperature value, controlling the vacuum device to evacuate the cooking cavity to form a negative pressure vacuum in the cooking cavity, so that The boiling temperature is lowered to the temperature where the rice grains have not started to gelatinize or have just started to gelatinize, that is, "low temperature boiling". The detached air bubbles generated by boiling disturb the rice grains, and the rice grains do not stick to each other under the disturbance to avoid agglomeration. To make rice grains more uniformly heated.
具体地,在进入升温沸腾阶段时,先控制加热装置进行加热工作以使提高烹饪腔内的温度,再控制真空装置对烹饪腔进行抽真空以降低烹饪腔内的压力,即先进行加热再进行抽真空。通过大量实验和理论分析得出,由于刚进入升温沸腾阶段,抽真空使烹饪腔内的 气体降低的幅度有限的情况下(如烹饪腔内的压力将至70kPa),沸点仍较高,过早抽气可能会使得烹饪腔内的饱和气体和底部气泡核心过早脱离到液体表面,不利于沸腾初期的气泡利用,所以先进行加热使底部形成一定热度再进行抽真空,沸腾效果更好。根据本申请的一个具体实施例,加热装置进行加热工作的时间可持续预设加热时间t2,其中,预设加热时间为0-20min,即0<t2<20min,后续再控制真空装置进行抽真空,以确保低温沸腾的效果。其中,预设加热时间优选为2min。Specifically, when the heating and boiling stage is entered, the heating device is first controlled to perform heating work so as to increase the temperature in the cooking cavity, and then the vacuum device is controlled to evacuate the cooking cavity to reduce the pressure in the cooking cavity, that is, the heating is performed first. Vacuum. Through a large number of experiments and theoretical analysis, it has been concluded that under the circumstances that the temperature in the cooking cavity is reduced by evacuating since the temperature has just entered the boiling stage (such as the pressure in the cooking cavity will reach 70kPa), the boiling point is still high and premature. Extraction may cause the saturated gas and the bottom bubble core in the cooking cavity to detach from the liquid surface prematurely, which is not conducive to the use of bubbles in the initial stage of boiling. Therefore, first heating to make the bottom a certain degree of heat and then vacuuming, the boiling effect is better. According to a specific embodiment of the present application, the heating device can perform the heating operation for a preset heating time t2, wherein the preset heating time is 0-20min, that is, 0 <t2 <20min, and the vacuum device is subsequently controlled to perform vacuuming. To ensure the effect of low temperature boiling. The preset heating time is preferably 2 min.
进一步地,根据本申请的一些实施例,先控制加热装置进行加热工作再控制真空装置对烹饪腔进行抽真空包括:当加热装置进行加热工作的时间达到预设加热时间时,控制真空装置进行抽真空,例如控制真空装置间隔地进行抽真空或连续地进行抽真空。其中,预设加热时间可为0-20min。Further, according to some embodiments of the present application, controlling the heating device to perform heating work first and then controlling the vacuum device to evacuate the cooking cavity includes: controlling the vacuum device to perform evacuation when the heating device performs heating work for a preset heating time. Vacuum, for example, the vacuum device is controlled to perform evacuation at intervals or continuously. The preset heating time can be 0-20min.
也就是说,对于先加热后抽真空,可先控制加热装置进行加热,以使烹饪腔内的温度升高,加热预设加热时间后,控制真空装置进行抽真空以使烹饪腔内的压力降低,烹饪腔内产生沸腾。这样更好确保底部米粒在未形成过度糊化前底部已形成大量的气泡脱离,米粒受气泡脱离产生的扰动影响而不粘结,最终使米饭受热均匀。That is, for heating first and then evacuating, you can control the heating device to heat first to increase the temperature in the cooking cavity. After heating for a preset heating time, control the vacuum device to vacuum to reduce the pressure in the cooking cavity. , Boiling occurs in the cooking cavity. In this way, it is better to ensure that a large number of air bubbles are formed at the bottom of the bottom rice grains before the excessive gelatinization is formed. The rice grains are not affected by the disturbance caused by the air bubble separation, and the rice is uniformly heated.
进一步地,根据本申请的一些实施例,在控制真空装置进行抽真空的过程中,还控制加热装置继续进行加热工作。Further, according to some embodiments of the present application, during the process of controlling the vacuum device to perform the vacuum, the heating device is also controlled to continue the heating work.
也就是说,当所述烹饪器具进入所述升温沸腾阶段时,先控制加热装置进行加热工作以提高烹饪腔内的温度,之后,再控制真空装置继续进行抽真空,同时可控制加热装置进行加热工作。That is, when the cooking appliance enters the heating and boiling phase, the heating device is first controlled to perform heating work to increase the temperature in the cooking cavity, and then the vacuum device is controlled to continue to evacuate, and the heating device can be controlled to be heated at the same time jobs.
也就是说,在先加热后可再同时加热和抽真空。可以理解的是,“同时进行加热和抽真空”可以是指,加热装置和真空装置存在一段时间是同时启动的。例如,在控制加热装置进行加热的时间达到预设加热时间后,可控制真空装置启动以对烹饪腔进行抽真空,此时,加热装置可在抽真空过程中的任一时刻启动,例如即在真空装置启动的同时控制加热装置启动以对烹饪腔进行加热工作,或者,在真空装置启动一段时间后再控制加热装置启动。而且,真空装置与加热装置可同时关闭,也可不同时关闭,即加热装置先关闭真空装置后关闭或真空装置先关闭加热装置后关闭。That is, heating and vacuum can be performed simultaneously after heating first. It can be understood that "simultaneously heating and vacuuming" can mean that the heating device and the vacuum device are activated simultaneously for a period of time. For example, after controlling the heating time of the heating device to reach a preset heating time, the vacuum device may be controlled to start to evacuate the cooking cavity. At this time, the heating device may be started at any time during the vacuuming process, for example, at When the vacuum device is started, the heating device is controlled to start to heat the cooking cavity, or the heating device is controlled to start after the vacuum device is started for a period of time. Moreover, the vacuum device and the heating device can be turned off at the same time, or they can be turned off at the same time, that is, the heating device is turned off first and then the vacuum device is turned off or the vacuum device is turned off first and then the heating device is turned off.
在本申请的一些实施例中,在先加热后抽真空或先加热后同时加热和抽真空之后,可控制加热装置继续进行加热或者不进行加热,并且可控制真空装置继续进行抽真空或者不进行抽真空。其中,加热装置和真空装置是否继续进行工作可根据烹饪过程的实际需求确定。例如,可根据升温速度需求控制加热装置间隔地进行加热工作或连续地进行加热工作; 而真空装置也可以根据烹饪腔内的压力间隔地进行抽真空或连续地进行抽真空。In some embodiments of the present application, the heating device may be controlled to continue heating or not to be heated after the first heating is followed by the vacuum or the first heating is followed by the simultaneous heating and the vacuum, and the vacuum device may be controlled to continue to perform the vacuum or not. Vacuum. Among them, whether the heating device and the vacuum device continue to work can be determined according to the actual needs of the cooking process. For example, the heating device can be controlled to perform the heating operation at intervals or continuously according to the demand of the heating rate; and the vacuum device can also perform the vacuum at intervals or continuously to perform the vacuum according to the pressure in the cooking cavity.
具体地,根据本申请的一个实施例,控制加热装置进行加热工作包括:Specifically, according to an embodiment of the present application, controlling the heating device to perform the heating work includes:
获取预设的升温速度;Get a preset heating rate;

如上所述,如图21所示,本申请实施例的烹饪器具的烹饪过程可包括预处理阶段A1、升温沸腾阶段A2、高温沸腾阶段A3和焖饭阶段A4。As described above, as shown in FIG. 21, the cooking process of the cooking appliance according to the embodiment of the present application may include a pre-treatment stage A1, a temperature-boiling stage A2, a high-temperature boiling stage A3, and a rice cooking stage A4.
具体地,在预处理阶段A1,可控制加热装置进行加热工作以使烹饪腔内的温度逐渐升高(如图21中的曲线Q1),当烹饪腔内的温度达到第一温度值T1时进入升温沸腾阶段。或者,在预处理阶段A1,记录预处理阶段的运行时间,并控制加热装置进行加热工作以使烹饪腔内的温度维持在预设吸水温度例如55℃以使米粒充分吸水,在预处理阶段的运行时间达到预设吸水时间例如10分钟时,控制加热装置进行加热工作以使烹饪腔内的温度继续升高,当烹饪腔内的温度达到第一温度值时进入升温沸腾阶段。并且,在预处理阶段A1,可控制真空装置进行抽真空,以降低烹饪腔内的压力(如图21中的曲线Q2),使米粒更多容易吸水,或者,也可控制真空装置不进行抽真空,即不降低烹饪腔内的压力,利用温度 升高来促进米粒吸水。Specifically, in the pre-processing stage A1, the heating device can be controlled to perform heating work to gradually increase the temperature in the cooking cavity (as shown by the curve Q1 in FIG. 21), and enter when the temperature in the cooking cavity reaches the first temperature value T1. Boiling stage. Alternatively, in the pre-processing phase A1, the running time of the pre-processing phase is recorded, and the heating device is controlled to perform the heating work so that the temperature in the cooking cavity is maintained at a preset water absorption temperature, such as 55 ° C. to allow the rice grains to fully absorb water. When the running time reaches a preset water absorption time, for example, 10 minutes, the heating device is controlled to perform heating work so that the temperature in the cooking cavity continues to rise, and when the temperature in the cooking cavity reaches the first temperature value, the heating and boiling phase is entered. In addition, in the pre-processing stage A1, the vacuum device can be controlled to evacuate to reduce the pressure in the cooking cavity (as shown by the curve Q2 in FIG. 21), so that the rice grains are more likely to absorb water, or the vacuum device can be controlled not to be evacuated. Vacuum, that is, does not reduce the pressure in the cooking cavity, uses the temperature increase to promote the rice grains to absorb water.
需要说明的是,在预处理阶段进行抽真空,以使烹饪腔内的压力达到预设吸水压力之后,可不再抽真空,烹饪腔内的压力将逐渐升高,或者,在预处理阶段进行抽真空,可以使烹饪腔内的压力达到预设吸水压力之后,继续抽真空以使烹饪腔内的压力维持在于预设吸水压力,其中,预设吸水压力小于标准大气压。It should be noted that after the vacuum is pre-processed so that the pressure in the cooking chamber reaches a preset suction pressure, the vacuum may no longer be evacuated, and the pressure in the cooking chamber will gradually increase. With vacuum, after the pressure in the cooking cavity reaches a preset suction pressure, the vacuum is continued to be maintained to maintain the pressure in the cooking cavity at the preset suction pressure, wherein the preset suction pressure is less than the standard atmospheric pressure.
在升温沸腾阶段A2,先控制加热装置进行加热工作即加热装置处于“on”状态且真空装置不进行抽真空即真空装置处于“off”状态,在达到预设加热时间后,控制加热装置进行加热工作即加热装置处于“on”状态,同时,控制真空装置进行抽真空即真空装置处于“on”状态,在先加热后同时进行加热和抽真空后,可根据升温速度需求控制加热装置间隔地进行加热工作或连续地进行加热工作;而真空装置可不再开启,烹饪腔内的压力逐渐升高,或者,真空装置也可以根据烹饪腔内的压力间隔地进行抽真空或连续地进行抽真空,烹饪腔内的压力维持在预设压力。In the heating and boiling phase A2, first control the heating device to perform the heating work, that is, the heating device is in the "on" state and the vacuum device is not in the vacuum state, that is, the vacuum device is in the "off" state. After the preset heating time is reached, the heating device is controlled to perform heating The heating device is in the "on" state when working, and the vacuum device is controlled to perform vacuuming, that is, the vacuum device is in the "on" state. After heating and vacuuming at the same time, the heating device can be controlled at intervals according to the heating rate. Heating work or continuous heating work; while the vacuum device can no longer be turned on and the pressure in the cooking cavity gradually increases, or the vacuum device can also be used to evacuate at intervals according to the pressure in the cooking cavity or continuously perform vacuuming and cooking The pressure in the cavity is maintained at a preset pressure.
在整个升温沸腾阶段A2,通过控制加热装置可以使烹饪腔内的温度从第一温度值T1开始上升至第二温度值T2,并且控制真空装置对烹饪腔进行抽真空以使烹饪腔内形成负压真空,烹饪腔在较低温度即大米糊化但未粘结成团前时产生沸腾气泡,从而确保米粒不结块,保持松散透热。并且,在烹饪器具的状态参数满足预设条件时控制真空装置关闭并控制压装置对烹饪腔进行泄气,使烹饪器具恢复到常压状态,迁移到高温沸腾阶段A3。Throughout the heating and boiling phase A2, the temperature in the cooking cavity can be increased from the first temperature value T1 to the second temperature value T2 by controlling the heating device, and the vacuum device is controlled to evacuate the cooking cavity to make the cooking cavity negative. Pressing the vacuum, the cooking cavity generates boiling bubbles at a lower temperature, that is, when the rice is gelatinized but not adhered to a mass, thereby ensuring that the rice grains do not agglomerate and keep loose heat. In addition, when the state parameters of the cooking appliance meet a preset condition, the vacuum device is controlled to be closed and the pressure device is controlled to deflate the cooking cavity to return the cooking appliance to a normal pressure state and migrate to the high-temperature boiling stage A3.
在高温沸腾阶段A3,由于沸腾的气孔和通道已经形成,不需要抽真空降低烹饪腔内的压力,可控制真空装置一直处于关闭状态,并且通过控制加热装置以第一功率进行加热,以使加热装置维持在预设沸腾温度,例如大气压沸点附近的温度或者高于98℃的温度,从而,烹饪腔内的米水维持高温沸腾状态,确保将米饭煮熟。并且,在高温沸腾阶段A3的运行时间达到预设高温沸腾时间之后,进入焖饭阶段A4。In the high-temperature boiling stage A3, because the boiling pores and channels have been formed, no vacuum is required to reduce the pressure in the cooking cavity. The vacuum device can be controlled to be always closed, and the heating device is controlled to heat at the first power to make the heating The device maintains a preset boiling temperature, such as a temperature near the boiling point of atmospheric pressure or a temperature higher than 98 ° C, so that the rice water in the cooking cavity maintains a high-temperature boiling state, ensuring that the rice is cooked. In addition, after the running time of the high-temperature boiling stage A3 reaches the preset high-temperature boiling time, the process proceeds to the rice-cooking stage A4.
在焖饭阶段A4,同样不需要抽真空降低烹饪腔内的压力,可控制真空装置一直处于关闭状态,并且通过控制加热装置以第二功率进行加热,以使加热装置维持在预设焖饭温度,例如预设焖饭温度大于第一温度值且小于第二温度值,从而,使米饭的香味和甜味更充足。其中,第二功率小于第一功率。In the rice cooking stage A4, there is also no need to evacuate to reduce the pressure in the cooking cavity. The vacuum device can be controlled to be always turned off, and the heating device is controlled to be heated at the second power to maintain the heating device at a preset rice cooking temperature. For example, the preset rice temperature is greater than the first temperature value and less than the second temperature value, so that the aroma and sweetness of the rice are more sufficient. The second power is smaller than the first power.

After cooking, non-negative pressure cooking after the high-temperature stable boiling phase and the rice-cooking phase is completed, and the cooking is finished. The specific steps can be as follows:

可以理解的是,在升温沸腾阶段,如果过早关闭真空装置,打开泄压装置使得烹饪腔内的压力与外部大气压一致,米水不能够很好沸腾。如果太迟关闭真空装置,沸腾后产生的水蒸气就会吸入真空装置例如真空泵内后排出,烹饪腔腔内的湿度下降,同时部分物质残留在真空泵内,易滋生细菌。基于此,需要在恰当的时刻停止抽取烹饪腔内的气体,实现更好的沸腾翻滚,同时防止沸腾后产生的水蒸气流失和吸入真空装置,防止滋生细菌。It can be understood that if the vacuum device is closed prematurely and the pressure relief device is opened during the temperature-boiling stage, the pressure in the cooking cavity is consistent with the external atmospheric pressure, and the rice water cannot boil well. If the vacuum device is turned off too late, the water vapor generated after boiling will be sucked into the vacuum device, such as a vacuum pump, and discharged. The humidity in the cooking cavity will drop, and some substances will remain in the vacuum pump, which will easily breed bacteria. Based on this, it is necessary to stop the extraction of the gas in the cooking cavity at the appropriate time to achieve better boiling and tumbling, and at the same time to prevent the loss of water vapor generated after boiling and inhalation of the vacuum device to prevent breeding of bacteria.
需要说明的是,在升温沸腾阶段,通过控制真空装置对烹饪腔进行抽真空,使得烹饪腔产生低温沸腾之后,随着烹饪腔内的米水不断沸腾,烹饪腔内产生大量的蒸汽,使烹饪腔内的压力无法维持在低气压值例如预设压力,烹饪腔内的压力将会一直上升,当烹饪腔内的压力上升速度较快时停止抽真空,直到烹饪完成。It should be noted that during the temperature-boiling stage, the cooking cavity is evacuated by controlling the vacuum device so that the cooking cavity generates low-temperature boiling. As the rice water in the cooking cavity continues to boil, a large amount of steam is generated in the cooking cavity to make cooking The pressure in the cavity cannot be maintained at a low air pressure value, such as a preset pressure. The pressure in the cooking cavity will always rise. When the pressure in the cooking cavity rises quickly, the vacuum will be stopped until the cooking is completed.
下面通过四个实施例来详细说明控制真空装置关闭的具体控制方式。The following describes in detail four specific control methods for controlling the closing of the vacuum device through four embodiments.

当所述温度在预设采样时间内上升速率小于预设温度上升速率时,控制所述真空装置关闭。When the temperature rise rate is less than the preset temperature rise rate within the preset sampling time, the vacuum device is controlled to be turned off.
需要说明的是,假设每隔预设采样时间采集一次温度,那么相邻两个温度的温度差值与预设采样时间的比值,即为烹饪腔内的温度在预设采样时间内上升速率。It should be noted that, assuming that the temperature is collected every preset sampling time, the ratio of the temperature difference between two adjacent temperatures to the preset sampling time is the rising rate of the temperature in the cooking cavity during the preset sampling time.

Stop extracting the gas in the cooking cavity to achieve better boiling and tumbling, at the same time prevent the loss of water vapor generated after boiling and suck into the vacuum device, and prevent the breeding of bacteria.

That is, the amount of rice water in the cooking cavity can be determined before the heating and boiling phase, and the preset closing temperature or the preset temperature rising rate can be determined according to the rice water in the cooking cavity during the heating and boiling phase.
其中,预设关闭温度与米水量呈正相关关系,即预设关闭温度随着米水量的增加而增加,而预设温度上升速率与米水量呈负相关关系,即预设关闭温度随着米水量的增加而减小。Among them, the preset shutdown temperature has a positive correlation with the amount of rice water, that is, the preset shutdown temperature increases as the amount of rice water increases, and the preset temperature rise rate has a negative correlation with the amount of rice water, that is, the preset shutdown temperature increases with the amount of rice water.

综上,根据本申请实施例提出的烹饪器具的烹饪控制方法,在烹饪腔内的温度达到第一温度值时确定烹饪器具处于升温沸腾阶段,并在烹饪器具处于升温沸腾阶段时,控制真空装置对烹饪腔进行至少一次抽真空,以使烹饪腔在烹饪腔内的温度达到第一温度值或大于第一温度值预设阈值时产生沸腾气泡,从而通过低温沸腾气泡扰动使米粒松散不黏结,确保米粒的受热均匀性,使得烹饪出来的米饭效果口感均匀、香味和甜味更充足。In summary, according to the cooking control method for a cooking appliance provided in the embodiment of the present application, when the temperature in the cooking cavity reaches a first temperature value, it is determined that the cooking appliance is in a boiling phase, and when the cooking appliance is in a boiling phase, the vacuum device is controlled. Vacuum the cooking cavity at least once so that when the temperature in the cooking cavity reaches the first temperature value or exceeds a preset threshold of the first temperature value, boiling bubbles are generated, so that the rice grains are loosened and not sticky by the disturbance of the low temperature boiling bubbles. To ensure the heating uniformity of the rice grains, the cooked rice will have a uniform taste, more flavor and sweetness.
根据本申请的一个实施例,烹饪器具的烹饪控制方法,还包括:当烹饪腔内的温度达到第一温度值之后,通过控制真空装置以使烹饪腔内的压力降低至预设压力,其中,预设压力小于大气压。According to an embodiment of the present application, the cooking control method for a cooking appliance further includes: after the temperature in the cooking cavity reaches a first temperature value, controlling the vacuum device to reduce the pressure in the cooking cavity to a preset pressure, wherein, The preset pressure is less than atmospheric pressure.
具体地,预设压力可根据米的糊化温度确定。更具体地,预设压力可为20kPa~60kPa。预设压力可优选为40kPa。Specifically, the preset pressure may be determined according to the gelatinization temperature of the rice. More specifically, the preset pressure may be 20 kPa to 60 kPa. The preset pressure may be preferably 40 kPa.
可理解,压力与沸点存在对应关系,压力越高沸点越高,压力越低沸点越低,根据米的糊化温度确定升温沸腾阶段需发生沸腾的温度点,并根据压力与沸点的对应关系确定预设压力。由此,在升温沸腾阶段,通过真空装置将烹饪腔内的压力降至相应的预设压力,使得烹饪腔内的温度达到米的糊化温度后烹饪腔内产生沸腾气泡。It can be understood that there is a corresponding relationship between the pressure and the boiling point. The higher the pressure, the higher the boiling point, and the lower the pressure. The lower the boiling point, the higher the boiling point, the lower the boiling point will be. Preset pressure. Therefore, in the temperature-boiling stage, the pressure in the cooking cavity is reduced to a corresponding preset pressure by the vacuum device, so that the boiling air bubbles are generated in the cooking cavity after the temperature in the cooking cavity reaches the gelatinization temperature of the rice.
举例来说,根据气压与沸点的对应关系可得,水在40kPa的压力值时沸点为76℃,由此,在进入升温沸腾阶段之后,通过开启真空装置以对锅内进行抽真空,并使烹饪腔内的气压维持在40kPa左右的负压值下,由于气泡的产生与脱离要在达到沸点前发生,因此,当烹饪腔内的米水温度达到60℃时,即开始产生气泡,气泡不断脱离对米粒形成扰动,使得米饭能够在不粘连的情况下加热,提升受热均匀性,这样烹饪出来的米饭口感均匀、香味和甜味更充足。For example, according to the corresponding relationship between air pressure and boiling point, it can be obtained that water has a boiling point of 76 ° C at a pressure value of 40 kPa. Therefore, after entering the boiling phase, the vacuum device is turned on to evacuate the inside of the pot, and The air pressure in the cooking cavity is maintained at a negative pressure of about 40kPa. Since the generation and disengagement of air bubbles must occur before the boiling point is reached, when the temperature of the rice water in the cooking cavity reaches 60 ° C, air bubbles begin to occur, and the air bubbles continuously Disturbance of the rice grains makes the rice heated without sticking and improves the uniformity of heating. In this way, the cooked rice has a uniform taste, more flavor and sweetness.
在本申请的实施例中,在烹饪腔内的压力降低至预设压力之后,可通过控制真空装置持续抽真空以使烹饪腔内的压力维持在预设压力,或者,可不再控制真空装置对烹饪腔进行抽真空以使烹饪腔内的压力,烹饪腔内的压力随着温度的升高而逐渐升高,或者,可在烹饪腔内的压力上升到第二压力值时,通过控制真空装置进行抽真空以使烹饪腔内的压力降低至预设压力,其中,第二压力值大于预设压力,例如第二压力值可为80kPa或常压即101kPa等。In the embodiment of the present application, after the pressure in the cooking cavity is reduced to a preset pressure, the vacuum device may be continuously evacuated by controlling the vacuum device to maintain the pressure in the cooking cavity at the preset pressure, or the vacuum device may no longer be controlled. The cooking cavity is evacuated to make the pressure in the cooking cavity, and the pressure in the cooking cavity gradually increases as the temperature rises. Alternatively, by controlling the vacuum device when the pressure in the cooking cavity rises to a second pressure value, Vacuuming is performed to reduce the pressure in the cooking cavity to a preset pressure, wherein the second pressure value is greater than the preset pressure, for example, the second pressure value may be 80 kPa or 101 kPa at normal pressure.
综上,根据本申请实施例提出的烹饪器具的烹饪控制方法,在烹饪腔内的温度达到第 一温度值时确定烹饪器具处于升温沸腾阶段,并在烹饪器具处于升温沸腾阶段时,控制真空装置对烹饪腔进行抽真空,以使烹饪腔在烹饪腔内的温度达到第一温度值或大于第一温度值预设阈值时产生沸腾气泡,从而通过低温沸腾气泡扰动使米粒松散不黏结,确保米粒的受热均匀性,使得烹饪出来的米饭效果口感均匀、香味和甜味更充足。并且,根据烹饪腔内的温度、烹饪腔内的压力和升温沸腾阶段的运行时间中至少一个控制真空装置关闭,能够实现更好的沸腾翻滚的同时,防止沸腾后产生的水蒸气流失和吸入真空装置,防止滋生细菌。In summary, according to the cooking control method for a cooking appliance provided in the embodiment of the present application, when the temperature in the cooking cavity reaches a first temperature value, it is determined that the cooking appliance is in a boiling phase, and when the cooking appliance is in a boiling phase, the vacuum device is controlled. Evacuate the cooking cavity so that when the temperature in the cooking cavity reaches the first temperature value or exceeds a preset threshold of the first temperature, boiling bubbles are generated, so that the rice grains are loosened and non-sticky by the disturbance of the low-temperature boiling bubbles to ensure the rice grains. The uniformity of heating results in the cooked rice having a uniform taste, more flavor and sweetness. In addition, the vacuum device is controlled to be closed according to at least one of the temperature in the cooking cavity, the pressure in the cooking cavity, and the operating time of the heating and boiling stage, which can achieve better boiling and tumbling while preventing water vapor generated after boiling and inhaling vacuum. Device to prevent breeding of bacteria.

The ratio of the second integral value between the points is smaller than the set ratio threshold. The set ratio threshold is equal to or less than 1, the second temperature point is greater than the first temperature point, and both the first temperature point and the second temperature point are less than the boiling temperature corresponding to the pressure value outside the pot.
其中,锅外气压值P0对应的沸腾温度可为100℃,即,第一温度点t1和第二温度点t2均可小于100℃。The boiling temperature corresponding to the pressure outside the pot P0 may be 100 ° C, that is, both the first temperature point t1 and the second temperature point t2 may be less than 100 ° C.
具体而言,在烹饪器具对内锅中的食材进行烹饪的过程中,锅内气压值Pe与烹饪食材的温度t存在着一定的关系,即Pe=f(t)。因此,在实际应用中,可计算出锅内气压值Pe在烹饪食材的第一温度点t1和第二温度点t2之间的第一积分值S1,即

Figure PCTCN2019098875-appb-000004
越小,则说明锅内气压值Pe与锅外气压值P0的偏差越大,即锅内气压值Pe越小。
Specifically, in the process of cooking the ingredients in the inner pot by the cooking appliance, there is a certain relationship between the air pressure value Pe in the pot and the temperature t of the cooking ingredients, that is, Pe = f (t). Therefore, in practical applications, the first integrated value S1 of the pressure value Pe in the pan between the first temperature point t1 and the second temperature point t2 of the cooking ingredients can be calculated, that is,

The smaller the value, the larger the deviation between the pressure value Pe inside the pot and the pressure value P0 outside the pot, that is, the smaller the pressure value Pe inside the pot.
由此,通过控制第一积分值S1与第二积分值S2的比值

小于某一设定值(即,设定比值阈值),可以准确地控制锅内气压值Pe小于某一气压值,以使烹饪器具内在较低的温度下,能够产生气泡,从而,在应用于煮饭时,能够在较低的温度下通过气泡对烹饪食材进行扰动,以避免烹饪食材因糊化而黏连,形成密集气泡通道,强化对流传热,使得烹饪食材均匀受热,在应用于煲汤时,能够使食材的营养物质充分溶于汤水中,产生更好的风味口感,同时,大大提高了烹饪器具烹饪出的食物的营养价值。
Therefore, by controlling the ratio of the first integrated value S1 to the second integrated value S2
Figure PCTCN2019098875-appb-000005
Less than a certain set value (that is, a set threshold value), the air pressure value Pe in the pan can be accurately controlled to be less than a certain air pressure value, so that bubbles can be generated at a lower temperature in the cooking appliance, thereby being applied in the application When cooking rice, the cooking ingredients can be disturbed by air bubbles at a lower temperature to prevent the cooking ingredients from sticking due to gelatinization, forming dense air bubble channels, enhancing convective heat transfer, and evenly heating the cooking ingredients.

具体地,在压力烹饪器具烹饪过程中,实时获取压力烹饪器具内的温度,并将该温度与第一预设温度阈值如60℃进行大小比较,也就是判断压力烹饪器具的烹饪过程是否进入升温沸腾阶段。当压力烹饪器具内的温度大于60℃时,说明压力烹饪器具的烹饪过程进入升温沸腾阶段,此时还需进一步确认压力烹饪器具内的温度是否大于60℃且小于75℃,也就是判断压力烹饪器具内的温度是否处于温度较低的T1阶段。当压力烹饪器具内的温度大于60℃且小于75℃,即处于温度较低的T1阶段时,该压力烹饪器具的控制装置控制抽气装置抽取锅体内的空气,并排出至锅体外,以将压力烹饪器具内的压力控制在第一压力范围内。Specifically, during the cooking process of the pressure cooking appliance, the temperature in the pressure cooking appliance is obtained in real time, and the temperature is compared with a first preset temperature threshold, such as 60 ° C., that is, it is determined whether the cooking process of the pressure cooking appliance has entered a temperature rise. Boiling stage. When the temperature in the pressure cooking appliance is greater than 60 ° C, it indicates that the cooking process of the pressure cooking appliance enters the boiling stage. At this time, it is necessary to further confirm whether the temperature in the pressure cooking appliance is greater than 60 ° C and less than 75 ° C, that is, to judge the pressure cooking. Whether the temperature in the appliance is in the lower T1 stage. When the temperature in the pressure cooking appliance is greater than 60 ° C and less than 75 ° C, that is, in the lower temperature T1 stage, the control device of the pressure cooking appliance controls the air extraction device to extract the air in the pot and discharge it to the outside of the pot, so as to The pressure in the pressure cooking appliance is controlled within a first pressure range.
当压力烹饪器具内的温度大于或等于75℃时,进一步判断压力烹饪器具内的温度是否大于75℃且小于90℃,也就是判断压力烹饪器具内的温度是否处于温度较高的T2阶段。当压力烹饪器具内的温度大于75℃且小于90℃,即处于温度较高的T2阶段时,该压力烹饪器具的控制装置抽取锅体内的空气,并排出至锅体外,以将压力烹饪器具内的压力控制在第二压力范围内。When the temperature in the pressure cooking appliance is greater than or equal to 75 ° C, it is further determined whether the temperature in the pressure cooking appliance is greater than 75 ° C and less than 90 ° C, that is, whether the temperature in the pressure cooking appliance is in the T2 stage where the temperature is high. When the temperature in the pressure cooking appliance is greater than 75 ° C and less than 90 ° C, that is, in the T2 stage with a high temperature, the control device of the pressure cooking appliance extracts the air from the pot and discharges it to the outside of the pot to place the pressure cooking appliance inside. The pressure is controlled within the second pressure range.

In order to make the boiling effect and the uniform heating effect better, the pressure in the pot is controlled at the first pressure range of 40kPa-60kPa at T1 stage. In the T2 stage, the pressure in the pot is controlled to a second pressure range of 50 kPa-90 kPa for experiments. The experimental results are shown in Table 7 below:

示例四:由表7可知,若按照表7所示的参数设计,则沸腾和受热效果是理想的,为进一步使成本再降低,低端产品也能实现因抽真空导致沸点降低所带来的受热性能提升,在该示例中,在T1阶段将锅内压力控制在第一压力范围60kPa-80kPa,在T2阶段将锅内压力控制在第二压力范围为70kPa-90kPa时进行实验,实验结果如下表8所示:Example 4: As can be seen from Table 7, if the parameters shown in Table 7 are designed, the boiling and heating effects are ideal. In order to further reduce costs, low-end products can also achieve the reduction in boiling point caused by vacuuming. The heating performance is improved. In this example, the pressure in the pot is controlled to the first pressure range of 60kPa-80kPa in the T1 stage, and the experiment is performed when the pressure in the pot is controlled to the second pressure range of 70kPa-90kPa in the T2 stage.

由于行业内评价米饭均匀受热和吸水性能的指标主要为沸孔数量、九点水分偏差率。沸孔数量的评判标准是:开口大小最大边长5mm,孔中间呈螺旋三角形,中间无米粒阻隔,即为沸孔。通常沸孔越多越均匀,则代表米饭沸腾越均匀。九点水分偏差率:如图30所示,取九个不同位置的米饭测其含水率,则九个不同位置的含水率偏差即为九点水分偏差,九点水分偏差数值越小,代表不同部位的米饭吸水受热越均匀。Due to the industry's indicators for evaluating the uniform heating and water absorption performance of rice are the number of boiling holes and the nine-point moisture deviation rate. The judging criterion for the number of boiling holes is: the maximum size of the opening is 5mm, the middle of the hole is a spiral triangle, and there is no grain barrier in the middle, which is the boiling hole. Generally, the more and more uniform the pores, the more uniform the rice will boil. Nine o'clock moisture deviation rate: As shown in Figure 30, take rice from nine different locations to measure its moisture content, then the water content deviation of nine different locations is the nine o'clock moisture deviation. The smaller the nine o'clock moisture deviation value, the different The more the rice is absorbed and heated, the more evenly.

Figure PCTCN2019098875-appb-000057
由表12可见,实施例四的米饭均匀性效果和米饭口感效果也处于较高的水平,但其沸孔数量有所下降,这与其过早气泡脱离及结合,气泡容易汇聚成大气泡穿透于米饭有一定相关性,同时要达到20kPa的低气压值,抽气装置和扛压结构的成本会大大提高,并不是最优的选择。It can be seen from Table 12 that the uniformity effect and the taste effect of rice in Example 4 are also at a high level, but the number of boiling holes has decreased. This results in the premature bubbles detachment and combination, and the bubbles easily converge into large bubbles and penetrate. There is a certain correlation between rice, and at the same time to reach a low pressure value of 20kPa, the cost of the suction device and the pressure-bearing structure will be greatly increased, which is not the optimal choice.
需要说明的是,在实际应用中,可根据实际情况进行设置参数,但综合效果,优选实施例三的参数作为最佳参数。It should be noted that, in practical applications, parameters can be set according to actual conditions, but for comprehensive effects, the parameters of the third preferred embodiment are used as the best parameters.
在本申请的另一个实施例中,如图30所示,该压力烹饪器具的控制方法,包括以下步骤:In another embodiment of the present application, as shown in FIG. 30, the method for controlling a pressure cooking appliance includes the following steps:
S1301,获取压力烹饪器具内的温度。S1301. Obtain the temperature in the pressure cooking appliance.
其中,可通过设置在锅体底部的温度获取模块如温度传感器实时获取压力烹饪器具内的温度或者通过设置在盖体内的温度获取模块如温度传感器实时获取压力烹饪器具内的温度。The temperature in the pressure cooking appliance can be obtained in real time by a temperature acquisition module such as a temperature sensor provided at the bottom of the pot body or the temperature in the pressure cooking appliance can be obtained in real time by a temperature acquisition module such as a temperature sensor provided in the lid body.
S132,判断压力烹饪器具内的温度是否大于第一预设温度阈值。S132: Determine whether the temperature in the pressure cooking appliance is greater than a first preset temperature threshold.
S1303,如果压力烹饪器具内的温度大于第一预设温度阈值且小于第二预设温度阈值,则将压力烹饪器具的压力变化值控制在第一变化范围内,其中,第一变化范围以第一预设温度阈值对应的压力为基准。在本申请的一个具体实施例中,第一变化范围可以为20kPa。S1303. If the temperature in the pressure cooking appliance is greater than the first preset temperature threshold and less than the second preset temperature threshold, control the pressure change value of the pressure cooking appliance within a first change range, where the first change range is The pressure corresponding to a preset temperature threshold is used as a reference. In a specific embodiment of the present application, the first variation range may be 20 kPa.
S1304,如果压力烹饪器具内的温度大于第二预设温度阈值且小于第三预设温度阈值,则将压力烹饪器具的压力变化值控制在第二变化范围内,其中,第二变化范围以第二预设温度阈值对应的压力为基准。在本申请的一个具体实施例中,第二变化范围可以为20kPa。S1304: If the temperature in the pressure cooking appliance is greater than the second preset temperature threshold and less than the third preset temperature threshold, control the pressure change value of the pressure cooking appliance within a second change range, where the second change range is The pressure corresponding to the two preset temperature thresholds is used as a reference. In a specific embodiment of the present application, the second variation range may be 20 kPa.
具体地,在压力烹饪器具烹饪过程中,实时获取压力烹饪器具内的温度,并将该温度与第一预设温度阈值如60℃进行大小比较,也就是判断压力烹饪器具的烹饪过程是否进入升温沸腾阶段。当压力烹饪器具内的温度大于第一预设温度阈值如60℃且小于第二预设温度阈值如75℃,即处于温度较低的T1阶段时,该压力烹饪器具的控制装置控制抽气装置抽取锅体中的空气,并排出至锅体外,以将压力烹饪器具内的压力变化值控制在以第一预设温度阈值对应的压力为基准的第一变化范围内。例如,参照图29,当压力烹饪器具内的温度为60℃时,对应的压力烹饪器具内的压力为40kPa,此时可将压力烹饪器具内的压力控制在40kPa-60kPa范围内,这样在该阶段的沸点在75℃以上90℃以下,通过控制压力烹饪器具内的压力缓慢上升,会有气泡冒出,随后在接近75℃时沸腾,能够减缓结块。Specifically, during the cooking process of the pressure cooking appliance, the temperature in the pressure cooking appliance is obtained in real time, and the temperature is compared with a first preset temperature threshold, such as 60 ° C., that is, it is determined whether the cooking process of the pressure cooking appliance has entered a temperature rise. Boiling stage. When the temperature in the pressure cooking appliance is greater than the first preset temperature threshold value such as 60 ° C and less than the second preset temperature threshold value such as 75 ° C, that is, in the T1 stage where the temperature is relatively low, the control device of the pressure cooking appliance controls the air extraction device The air in the pot is extracted and discharged to the outside of the pot to control the pressure change value in the pressure cooking appliance within a first change range based on the pressure corresponding to the first preset temperature threshold. For example, referring to FIG. 29, when the temperature in the pressure cooking appliance is 60 ° C, the pressure in the corresponding pressure cooking appliance is 40kPa. At this time, the pressure in the pressure cooking appliance can be controlled within the range of 40kPa-60kPa. The boiling point of the stage is above 75 ° C and below 90 ° C. By slowly increasing the pressure in the pressure-controlled cooking appliance, bubbles will pop out and then boil at approximately 75 ° C, which can slow down the agglomeration.
当压力烹饪器具内的温度大于第二预设温度阈值如75℃且小于第三预设温度阈值如90℃,即处于温度较高的T2阶段时,该压力烹饪器具的控制装置同样控制抽气装置抽取锅体内的空气,并排出至锅体外,以将压力烹饪器具内的压力变化值控制在以第二预设温度阈值对应的压力为基准的第二变化范围内。例如,继续参照图29,当压力烹饪器具内的温度为75℃时,对应的压力烹饪器具内的压力为50kPa,此时可将压力烹饪器具内的压力控制在50kPa-70kPa范围内,这样在该阶段的沸点在85℃以上96℃以下,锅内会不断沸腾并产生大量蒸汽,锅内压力Pe缓慢上升,锅内温度也在上升,能够使得米水保持良好的受热效果。When the temperature in the pressure cooking appliance is greater than the second preset temperature threshold value such as 75 ° C and lower than the third preset temperature threshold value such as 90 ° C, that is, in the T2 stage with a higher temperature, the control device of the pressure cooking appliance also controls the air extraction The device extracts the air inside the pot and discharges it to the outside of the pot to control the pressure change value in the pressure cooking appliance within a second change range based on the pressure corresponding to the second preset temperature threshold. For example, continuing to refer to FIG. 29, when the temperature in the pressure cooking appliance is 75 ° C, the pressure in the corresponding pressure cooking appliance is 50kPa. At this time, the pressure in the pressure cooking appliance can be controlled within the range of 50kPa-70kPa. The boiling point at this stage is above 85 ° C and below 96 ° C. The pot will continuously boil and generate a large amount of steam. The pressure Pe in the pot will rise slowly, and the temperature in the pot will also rise, which can maintain good heating effect for rice water.
