Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A control method of a cooking appliance and the cooking appliance according to an embodiment of the present invention are described below with reference to the accompanying drawings.
First, in a cooking mode, the cooking appliance of the embodiment of the present invention can perform negative pressure cooking on food, that is: the inner pot is in a negative pressure state to cook food.
Specifically, as shown in fig. 1, the cooking appliance 200 includes: an inner pot 210, a heating device 220, a pot body 230, a pot cover 240, an air pressure adjusting device 250 and a controller 260.
Wherein, the inner pot 210 is used for containing food to be cooked. The heating means 220 is used to heat the inner pot 210. The pot body 230 is used for carrying the inner pot 210. Pot cover 240 is connected to pot body 230, and pot body 240 is used to enclose inner pot 210 or pot body 230. The air pressure adjusting means 250 is provided on the lid 240 for adjusting the air pressure of the inner pot 210. The controller 260 is configured to control the heating device 220 to heat the inner pot 210 after entering the cooking mode, and control the air pressure adjusting device 250 to draw a vacuum to the inner pot 210, so that the inner pot 210 cooks food under negative pressure.
The air pressure adjusting device 250 includes, but is not limited to, an air pump 251 and a valve 252, when negative pressure is required in the inner pan 210, the valve 250 can be opened, air is pumped from the inner pan 210 by the air pump 250, a certain vacuum degree is generated in the inner pan 210, and negative pressure is generated in the inner pan 210, that is: the air pressure in the inner pot 210 is less than the outside air pressure. In addition, when positive pressure is needed in the inner pan 210, the valve 252 can be opened, air is input into the inner pan 210 through the air pump 250, so that the pressure in the inner pan 210 is increased, and positive pressure is generated in the inner pan 210, that is: the air pressure inside the inner pot 210 is greater than the outside air pressure.
It is understood that the manner of generating the positive pressure in the inner pot 210 is not limited to the manner realized by the air pressure adjusting device 250, and the positive pressure may be generated by the water vapor after the inner pot is heated, similar to the electric pressure cooker in the related art.
The cooking appliance 200 further comprises an exhaust valve 270, and the exhaust valve 270 is used to open when the air needs to be exhausted so as to exhaust the air pressure in the inner pot 210.
When the cooking appliance is in a cooking mode, the heating device is started to heat the inner pot, and the air pressure adjusting device is controlled to extract vacuum from the inner pot so that the inner pot cooks food under negative pressure.
Specifically, when the cooking electric appliance works, the cooking electric appliance enters a cooking mode including a cooking mode, a heat preservation mode, a pressure maintaining mode and other modes, a heating device is started, and the heating device is controlled to run at rated power so as to heat the inner pot at an accelerated speed. And (4) vacuumizing the inner pot, and stopping vacuumizing the inner pot until the vacuum degree of the inner pot reaches a preset vacuum degree. Wherein the predetermined degree of vacuum is, for example, greater than or equal to 50 Kpa.
During cooking, the temperature distribution within the cooking chamber is not uniform. Since the heat output from the heating device in the cooking appliance is gradually transferred from the bottom to the top of the cooking material, the temperature of the cooking cavity assumes a layered state. Specifically, since the bottom of the cooking chamber is in direct contact with the heater, the temperature at the bottom of the cooking chamber is the highest, the temperature at the middle is the next lowest, and the temperature at the top of the cooked food is the lowest.
In the embodiment of the invention, because the temperature in the cooking cavity is layered, the bottom of the cooking cavity reaches the boiling point firstly to generate bubbles, and the generated bubbles are used for stirring the cooking food. But since the temperatures of the middle and top portions are now lower than the bottom portion, the temperatures of the middle and top portions do not reach boiling points and the entire cooking chamber does not really go to boiling. In other words, the bubbles generated in the embodiment of the present invention are generated when the bottom of the cooking cavity reaches the boiling point.
The gelatinization temperature of the rice grains is usually about 62 ℃, the rice grains are easy to be bonded into a mass after gelatinization and block heat convection, and in order to enable the rice grains to generate bubbles before gelatinization, the vacuum of the inner pot is extracted to reduce the boiling point, so that the rice grains generate bubbles as far as possible before the gelatinization temperature, a dense bubble channel is formed, and the convection heat transfer is enhanced. Vacuumizing from water absorption to heating, raising temperature, maintaining the vacuum degree above 50Kpa (boiling point 80 ℃), and stopping vacuumizing when reaching the stable boiling point 80 ℃. In the process of heating rice, the rice grains are bonded into lumps, and the rice is heated unevenly, but in the process of heating rice, the rice grains generate bubbles before being agglomerated, so that more continuous bubble channels distributed more evenly are formed, convection heat transfer is enhanced, the rice is heated evenly in the whole process, and the quality of the rice is improved.
It is understood that the vacuum level of 50Kpa is merely exemplary and may be appropriately adjusted according to specific requirements.
In addition, the inner surface of the inner pot in the embodiment of the invention is sprayed with the non-stick coating, so that bubbles generated at the bottom of the pot can slide and separate quickly, more bubble channels can be formed quickly, and the bubbles can act on the cooked food more uniformly.
This cooking utensil can make interior pot form the negative pressure through atmospheric pressure adjusting device, because the boiling point reduces, and the bubble is produced promptly at the bottom of a boiler before the rice grain gelatinization, forms dense bubble passageway, and intensive convection heat transfer to make the whole thermally equivalent of rice, finally promote the quality of rice.
Because during the negative pressure culinary art, the boiling point reduces, and the boiling can be more violent than conventional cooking utensil, and the bubble that the boiling produced probably carries food waste and will extract vacuous extraction opening and pressure release hole jam in culinary art process, will influence the extraction vacuum, still can produce the malleation when the pressure release hole is blockked up moreover, has the risk of uncapping abnormally.
Accordingly, an embodiment of the present invention discloses a control method of a cooking appliance.
The specific structure of the cooking appliance is shown in fig. 1. In addition, the cooking appliance further comprises an air suction opening and a pressure relief opening, wherein the air pressure adjusting device 250 is used for controlling the opening and closing of the air suction opening, and the exhaust valve 270 is used for controlling the opening and closing of the pressure relief opening.
As shown in fig. 2, in conjunction with fig. 3 and 4, a method for controlling a cooking appliance includes:
s201: in the cooking mode, an overflow signal is detected when the food boils.
Wherein, whether the overflow phenomenon occurs can be detected by the sensor.
S202: if an overflow signal is detected, the air suction opening is closed to stop vacuum suction of the inner pot, and the pressure relief hole is controlled to be opened to relieve pressure of the inner pot.
Specifically, in the boiling stage, when overflow detection sensors such as an overflow prevention electrode or an infrared sensor detect overflow signals, the electromagnet works to drive the pressure relief hole to be suddenly opened, the pressure in the cooking appliance is suddenly changed from negative pressure to external atmospheric pressure, bubbles in the cooking appliance are broken under the action of pressure difference, and the electromagnetic valve and the vacuum pump (air pump) stop working and do not extract vacuum when the pressure relief hole is opened. The time from negative pressure to external pressure in the cooking utensil in the sudden pressure relief process is t.
In a specific example of the present invention, the method further includes: and judging whether the overflow signal disappears. If the overflow signal disappears, the air suction opening is opened after the first preset time is delayed to suck vacuum for the inner pot, and the pressure relief hole is controlled to be closed to stop relieving pressure for the inner pot.
Namely: when the overflow signal disappears, the electromagnet drives the pressure relief hole to be closed, if the boiling stage is not finished, the electromagnetic valve and the vacuum pump start to work to extract vacuum from the cooking appliance, meanwhile, the overflow signal in the cooking appliance is detected, and the circulation work is carried out until the boiling stage is finished.
In a specific example, the method for controlling a cooking appliance further includes: obtaining the first predetermined time T corresponding to the cooking function according to the cooking function selected in the cooking mode. For example: the value range of the easily spilled food such as porridge cooking is as follows: 3s < T <30s, if for food which is not easy to overflow, the value range of T is as follows: 0< T <15 s.
Further, if an overflow signal is detected, the air suction port is closed to stop vacuum suction to the inner pot, and the pressure relief hole is controlled to be opened to relieve pressure to the inner pot, including: closing the air pumping port to stop pumping vacuum to the inner pot; and controlling the pressure relief hole to open for a second preset time t. Wherein the second predetermined time is 0-30 seconds.
That is, after the overflow signal is detected, the electromagnetic valve and the vacuum pump do not work any more, at the moment, the electromagnet works, the pressure relief valve is opened under the action of the electromagnet, the negative pressure in the cooking utensil is suddenly changed into the external pressure, and the bubbles are broken under the action of the instant pressure difference; when the air bubble disappears, the air leakage port is closed, the electromagnetic valve and the vacuum pump work, and meanwhile, an overflow signal is detected until the end is reached; protecting the time t required for the air pressure to be released to the external pressure from the negative pressure after the pressure release hole of the negative pressure low-temperature boiling cooking utensil is opened, wherein the value range of t is 0s < t <30 s; when the overflow signal disappears, the pressure relief hole is not immediately closed and vacuum is extracted, and the phenomenon of reboiling immediately is caused if the thermal inertia immediately closes the pressure relief hole and vacuum is extracted, so that the pressure relief hole is closed and vacuum is extracted after the time T, as shown in FIG. 2, T is T4-T3; for time T, the value ranges of different cooking functions are different, and the value ranges of foods which are easy to overflow such as porridge and the like are as follows: 3s < T <30s, if for food which is not easy to overflow, the value range of T is as follows: 0< T <15 s; after the overflow signal disappears in the boiling stage, the electromagnetic valve and the vacuum pump continuously perform the vacuum pumping operation because the rising speed of the air pressure in the cooking utensil is faster.
According to the control method of the cooking utensil provided by the embodiment of the invention, when the overflow signal is detected, the air exhaust port is controlled to be closed to stop vacuumizing, the pressure relief hole is controlled to be opened to relieve pressure, negative pressure in the cooking utensil is suddenly changed into external pressure, and the air bubbles are broken under the action of pressure difference, so that the air bubbles and food residues can be effectively prevented from overflowing, and the blockage of the air exhaust port and the pressure relief hole by the food residues is avoided.
As shown in fig. 1, an embodiment of the present invention discloses a cooking appliance, including: the cooker comprises an inner pot 210, a heating device 220, a pot body 230, a pot cover 240, an air suction opening for sucking vacuum from the inner pot, a pressure relief hole for relieving pressure from the inner pot, and a controller 260, wherein an air pressure adjusting device 250 is used for controlling the opening and closing of the air suction opening. The vent valve 270 is used to control the opening and closing of the pressure relief vent.
The controller 260 is configured to detect an overflow signal when food boils in a cooking mode, and if the overflow signal is detected, close the air suction port to stop vacuum suction of the inner pot, and control the opening of the pressure relief hole to relieve pressure of the inner pot.
Further, the controller 260 is further configured to determine whether the overflow signal disappears, and if the overflow signal disappears, open the air pumping hole after delaying for a first predetermined time to pump vacuum to the inner pot, and control the pressure relief hole to close to stop releasing pressure to the inner pot.
In an embodiment of the present invention, the controller 260 is further configured to obtain the first predetermined time corresponding to the cooking function according to the cooking function selected in the cooking mode.
In an embodiment of the present invention, when the air suction port is closed to stop vacuum suction to the inner pot and the pressure relief hole is controlled to be opened to relieve pressure to the inner pot if the overflow signal is detected, the controller 260 specifically closes the air suction port to stop vacuum suction to the inner pot and controls the pressure relief hole to be opened for a second predetermined time.
Wherein the second predetermined time is, but not limited to, 0-30 seconds.
In one embodiment of the present invention, the cooking appliance includes, but is not limited to, an electric rice cooker, and an electric pressure cooker.
According to the cooking utensil disclosed by the embodiment of the invention, when the overflow signal is detected, the air exhaust port is controlled to be closed to stop vacuumizing, the pressure relief hole is controlled to be opened to relieve pressure, negative pressure in the cooking utensil is suddenly changed into external pressure, and the air bubbles are broken under the action of pressure difference, so that the air bubbles and food residues can be effectively prevented from overflowing, the air exhaust port and the pressure relief hole are prevented from being blocked by the food residues, and the quality of the cooking utensil is improved.
