The technical solutions of the embodiments of the present invention are explained and illustrated below with reference to the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, and not all embodiments. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative effort belong to the protection scope of the present invention.
Referring to fig. 1 to 3, a cooking control method of opening a cover halfway of a steam rice cooker proposed in an embodiment of the present invention, wherein the steam rice cooker includes a cooker body 100 and a cooker cover 200, the cooker cover 200 covers the cooker body 100 to form a cooking cavity, the cooker body 100 has a steam generator 400 for supplying steam to the cooking cavity, specifically: the steam rice cooker of the embodiment is of a split structure, that is, the cooker cover 200 is detachably covered on the cooker body 100, so that the convenience of use of a user is increased, for example, the cooker cover 200 is convenient to be cleaned independently; the inner container 300 is placed in the pot body 100, the pot cover 200 and the inner container 300 form a cooking cavity when covering the pot body 100, the pot body 100 is provided with a steam output pipeline 110 connected with the steam generator 400, and the upper part of one side of the pot body 100 is provided with an air outlet 111 of the steam output pipeline 110; the cooker cover 200 is provided with a steam input pipeline 210 communicated to the cooking cavity, and the bottom of one side of the cooker cover 200 is provided with an air inlet 211 of the steam input pipeline 210. The cooker cover 200 is closed, the air outlet 111 of the steam output pipeline 110 is communicated with the air inlet 211 of the steam input pipeline 210, and the steam generated by the steam generator 400 is transmitted to the cooking cavity through the steam output pipeline 110 and the steam input pipeline 210 for heating food; after the pot cover 200 is opened, the air outlet 111 of the steam output line 110 and the air inlet 211 of the steam input line 210 are separated from each other. The steam rice cooker further has a water tank 600 and a water pump 500, and water in the water tank 600 is drawn into the steam generator 400 by the power supplied from the water pump 500.
According to the steam rice cooker of the embodiment, during a heating stage of a certain cooking procedure (for example, a heating stage, a boiling stage, etc. of the cooking procedure), the steam generator continuously outputs high-temperature steam, and if a user opens the cooker cover to add food or observe a cooking state of the food, the high-temperature steam sprayed from the air outlet of the steam output pipeline easily scalds the user. Therefore, the measures adopted in the prior art are that the steam generator is directly stopped after the cover opening action is detected, so that the safety of the cover opening operation can be ensured, but the heat loss of food can be caused by stopping heating, and the steam temperature before the cover opening can be recovered only by preheating for a certain time after the cover is closed again, so that the food cooking quality is reduced; in addition, the start-stop of the steam generator is usually controlled by a switching device, and frequent switching of the steam generator and its switching device reduces its lifetime.
In view of the above problem, the cooking control method according to the present embodiment includes: detecting the opening and closing state of the cooker cover in the cooking process of the steam rice cooker; judging a heating mode of the steam generator 400 if the open state of the boiler cover 200 is detected; if the steam generator 400 is in the normal heating mode, it is switched to the low power heating mode.
According to the cooking control method provided by the embodiment, when the opening state of the cooker cover 200 is detected in the cooking process, the steam generator 400 is switched to the low-power heating mode, and the steam generator 400 is maintained to work in a state of lower power than the normal heating mode, so that on one hand, a certain temperature can be maintained in the steam generator 400 after the cover of the steam rice cooker is opened, the normal heating mode can be quickly recovered without preheating after the cover is closed again, high-temperature steam can be prevented from being output after the cover is opened, and the safety of midway cover opening operation is improved; on the other hand, if the operation of the steam generator 400 needs to be stopped without considering other factors, the steam generator 400 does not need to be repeatedly started and stopped, the switching times of related switching devices are reduced, the service lives of the switching devices are prolonged, and the problems of voltage fluctuation and the like caused by frequent switching of the switching devices are avoided.
According to the cooking control method of the present embodiment, if the steam generator 400 is in the non-operating state during the cooking of the steam rice cooker, the steam generator 400 continues to maintain the non-operating state when the open state of the cooker cover 200 is detected. Taking the rice cooking procedure as an example, the steam generator 400 is not required to supply steam during the water absorption stage of the rice cooking procedure, so the steam generator 400 is in the non-operation state, and if the user opens the pot cover 200 during the water absorption stage of the rice cooking procedure, the steam generator 400 continues to remain in the non-operation state without switching to the low power heating mode.
Preferably, when the open state of the pot cover 200 is detected, the water pump 500 stops operating. Specifically, the steam generator 400 maintains heating at a lower power than the normal heating mode in the low power heating mode, the water pump 500 stops supplying water during the uncovering time, and the steam generator 400 cannot generate steam or a mixture of steam and water even if it is heated, thereby preventing the steam or the mixture of steam and water from being ejected from the air outlet 111 of the steam output pipe 110.
Preferably, the water pump 500 decreases the flow rate when the open state of the pot cover 200 is detected. Specifically, the steam generator 400 maintains heating at a lower power than the normal heating mode in the low power heating mode, and the water pump 500 delivers only a small amount of water to the steam generator 400 during the uncapping time, and the water is heated by the steam generator 400 during the uncapping time, and steam can be generated more rapidly after the recapping.
In other embodiments, when the opening state of the pot cover 200 is detected, the water pump 500 can also maintain the original operation state, for example, the water pump 500 maintains the flow rate before opening the cover, since the steam generator 400 is heated at low power after the pot cover 200 is opened, the steam mixture with lower temperature is sprayed out of the air outlet 111 of the steam output pipeline 110, and the scald risk is lower compared with the high-temperature steam generated in the normal heating mode.
In this embodiment, the power of the steam generator 400 in the normal heating mode is P1, the power in the low power heating mode is P2, in the specific implementation, if the power P2 is set too low, it is difficult to maintain the internal temperature of the steam generator 400 for a long time, and if the power P2 is set too high, there is a risk of scalding due to the steam temperature being too high, so this embodiment satisfies P1/16 ≦ P2 ≦ P1/3, for example: the power P1 of the steam generator 400 in the normal heating mode is 300W-900W, and the power P2 of the low power heating mode is set to 50W-100W, and the specific power can be set according to the type, size and other requirements of the steam generator 400.
In order to realize the cover opening detection, the present embodiment provides an inductive switch on the cooker body 100, and the steam rice cooker detects the opening and closing state of the cooker cover 200 according to the inductive signal of the inductive switch, which is as follows: the induction switch is a microswitch, the microswitch is in a conducting state when the pot cover 200 is in a closed state, the microswitch is in a disconnected state when the pot cover 200 is in an open state, and the opening and closing state of the pot cover 200 can be judged according to a conducting or disconnecting signal of the microswitch. In other embodiments, the inductive switch may also be a photoelectric inductive switch (such as an infrared sensor), a magnetic control switch (such as a reed switch), etc., and the uncovering detection performed by using the inductive switch can be performed independently, so that the obtained uncovering detection information does not interfere with the detection information in the original cooking program, and the accuracy of the uncovering detection can be ensured without affecting the normal cooking program.
Referring to fig. 1 to 3, in an embodiment of the present invention, a cooking control method based on the above embodiment: the steam rice cooker continues to detect the opening and closing state of the cover after the cover 200 is opened, and the steam generator 400 stops operating if the cover 200 is not closed within a predetermined time.
If the pot cover 200 is not closed within the predetermined time, which is usually the case that the user does not complete the related operation within the predetermined time, or forgets to close the pot cover 200, the steam generator 400 is directly turned off in this case, thereby avoiding waste of electricity due to long-time operation of the steam generator 400. The preset time of the embodiment is set to be 2-10 min, and actually, the preset time can be selected according to the difference of cooking programs, for example, the cooking program needing no midway feeding is short, the cooking program needing to be added with a plurality of materials midway or needing to be fed for a plurality of times is short, and the preset time is long.
As described above, if the pot cover 200 is closed within the predetermined time, the steam generator 400 is restored to the normal heating mode, and the steam rice pot continues to perform the cooking process before the pot cover 200 is opened. Specifically, when the open state of the cooker cover 200 is detected during the cooking process, the control system of the steam rice cooker saves the current cooking data, and automatically executes the cooking program before the cooker cover 200 is opened after the cooker cover 200 is closed again, without resetting the cooking program by the user.
Preferably, the steam rice cooker of the embodiment further comprises an alarm device, if the cooker cover 200 is detected to be in an open state in the cooking process, the alarm device gives an alarm to remind a user, the probability that the user forgets to close the cooker cover is reduced, the use experience is improved, and if the cooker cover 200 is closed within a preset time, the alarm device releases the alarm. The alarm mode of the alarm device includes but is not limited to voice prompt, nixie tube/LED lamp prompt and buzzer prompt.
While the invention has been described with reference to specific embodiments thereof, it will be understood by those skilled in the art that the invention is not limited thereto, but rather is intended to cover all modifications and equivalents falling within the spirit and scope of the present invention as defined by the appended claims. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
