Detailed Description
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.
As shown in fig. 1 to 12, the cooking control method of the first embodiment is applied to a cooking appliance, the cooking appliance including: cooking chamber 1, suction chamber 2, float 40, float drive mechanism and suction device 60. Wherein, a communication channel 231 is arranged between the pumping chamber 2 and the cooking chamber 1 so that the gas in the cooking chamber 1 can be pumped out through the pumping chamber 2. A float 40 is provided in the communication passage 231, the float 40 having a suction position for communicating the suction chamber 2 with the cooking chamber 1 and a sealing position for not communicating the suction chamber 2 with the cooking chamber 1. The float drive mechanism drives the float 40 from the suction position to the sealing position. The suction port of the suction device 60 communicates with the suction chamber 2. The cooking control method of the present embodiment includes: after the trigger signal is detected, the air extracting device 60 starts air extracting from the air extracting cavity 2 in response to the trigger signal; under a first preset condition, the float driving mechanism drives the float 40 to move from the air suction position to the sealing position; in the second preset condition, the air extraction device 60 stops air extraction.
By applying the technical scheme of the embodiment, the cooking control method comprises the following steps: after the trigger signal is detected, the communication passage 231 is in an open state, and the air extracting device 60 starts air extraction from the air extracting chamber 2 in response to the trigger signal; under a first preset condition, the float driving mechanism drives the float 40 to move from the pumping position to the sealing position, so that the cooking cavity 1 and the pumping cavity 2 are not communicated with each other. At this time, the air extraction device 60 still extracts air from the air extraction chamber 2. Since the cooking chamber 1 and the pumping chamber 2 are not communicated with each other, the pumping device 60 actually pumps only the pumping chamber 2, so that the pressure in the pumping chamber 2 gradually decreases. When the second preset condition is satisfied, the air extracting device 60 stops air extraction. The pressure in the cooking chamber 1 is now greater than the pressure in the evacuation chamber 2 to keep the float 40 in a sealed position. Since the float 40 is maintained at the sealed position, the communication passage 231 is blocked, the pumping chamber 2 and the cooking chamber 1 are not communicated with each other, and the cooking chamber 1 forms a closed space, so that it can be ensured that the pressure in the cooking chamber 1 can reach a predetermined value during normal operation. The cooking control method can realize the opening and closing of the communication channel, and solves the problem that the cooking utensil in the prior art can not effectively realize the opening and closing of the communication channel.
As shown in fig. 5 to 10, in the first embodiment, in the first preset condition, the float driving mechanism driving the float 40 to move from the suction position to the sealing position includes: detecting the pressure inside the cooking chamber 1; in the case that the pressure in the cooking cavity 1 is less than or equal to a first preset pressure value, the float driving mechanism drives the float 40 to move from the air suction position to the sealing position; in a second preset condition, the stopping of the air extraction by the air extractor 60 includes: detecting the pressure in the pumping chamber 2; in the case that the pressure in the pumping chamber 2 is less than or equal to the second preset pressure value, the pumping device 60 stops pumping, wherein the second preset pressure value is less than the first preset pressure value. The control method controls the movement of the float 40 by measuring the pressures in the cooking chamber 1 and the pumping chamber 2, so that the control result is more accurate. The pressure in the cooking cavity 1 can be accurately ensured to be smaller than or equal to a first preset pressure value, so that the cooking effect is better.
It should be noted that, the cooking appliance of the first embodiment includes two stages in total during operation, one is a pickling stage and the other is a heating stage. Wherein, during the pickling stage, the communication channel 231 needs to be opened to exhaust air from the cooking cavity 1, so that the pressure in the cooking cavity 1 is smaller than or equal to a first preset pressure value, thereby ensuring the pickling effect. After the curing stage has ended, the float 40 needs to be moved to a sealed position and then heated. Since the communication passage 231 is blocked, the cooking chamber 1 is airtight, and thus a high pressure cooking function can be ensured.
In the first embodiment, the float driving mechanism applies an upward force to the float 40 after the float driving mechanism drives the float 40 from the suction position to the sealing position, and before the suction device 60 stops suction. So that the pumping chamber and the cooking chamber are not communicated with each other during the above-mentioned time period. After the suction device 60 stops suction, the pressure differential between the suction chamber and the cooking chamber is sufficient to overcome the weight of the float 40, at which point the float drive mechanism stops applying upward force to the float 40. The control method enables the floater 40 to be propped against the sealing position without depending on external force (force applied by the floater driving mechanism) in the subsequent heating stage, shortens the working time of the floater driving mechanism and prolongs the service life of the floater driving mechanism.
Since some cooking appliances do not have a measuring element for measuring pressure, in order to enable the cooking appliances without a load cell to have the pickling function, the application also provides a second embodiment. The second embodiment of the cooking control method of the present application is different from the first embodiment of the cooking control method of the present application in the first preset condition and the second preset condition. Specifically, in the second embodiment, under the first preset condition, the float driving mechanism driving the float 40 to move from the suction position to the sealing position includes: when the working time period of the cooking utensil is longer than or equal to a first preset time interval, the float driving mechanism drives the float 40 to move from the air suction position to the sealing position; in a second preset condition, the stopping of the air extraction by the air extractor 60 includes: in the case that the operation time of the cooking appliance is equal to or longer than the second preset time interval, the air extraction device 60 stops the air extraction, wherein the second preset time interval is longer than the first preset time interval. The control method controls the movement of the float 40 by measuring the working time of the cooking appliance, and the control result is accurate, thereby ensuring the cooking effect.
The following will take 50 minutes for the pickling stage, the first preset time interval being 40 minutes and the second preset time interval being 50 minutes as an example:
after the trigger signal is detected, the evacuation device 60 starts evacuating the evacuation cavity 2 in response to the trigger signal. When the cooking appliance operating time (the time interval from the time when the trigger signal is detected to the current time) is 40 minutes or more, the float driving mechanism drives the float 40 to move from the suction position to the sealing position. When the cooking appliance operating time (the time interval from the time when the trigger signal is detected to the current time) is 50 minutes or more, the air extraction device 60 stops air extraction. Of course, those skilled in the art will appreciate. The pickling stage, the first preset time interval and the second preset time interval are not limited to the above-mentioned time.
Note that, a gas leakage phenomenon may occur in the cooking cavity 1, and a cooking appliance having a volume of 5L will be described below:
in order to ensure that the service life and noise of the air extractor 60 reach ideal values, the air extractor 60 has the flow of 1.3-1.5L/min, and the self air extracting capacity of the air extractor 60 is between-55 and-60 kp. On this basis the following test results were obtained:
Under the condition that nothing is contained in the cooking cavity: the single air extractor 60 works continuously for about 5min, the negative pressure value in the cooking cavity can reach-45 kp, the air extractor 60 continues to work, and the pressure in the cooking cavity drops slowly and is basically unchanged.
When the water content reaches the maximum scale on the inner wall of the cooking cavity: the single air extractor 60 works continuously for about 2min, the negative pressure value in the cooking cavity can reach-45 kp, and the pressure in the cooking cavity continuously operated by the air extractor 60 drops slowly and is basically unchanged.
After-45 kp is reached in the cooking cavity, the suction device 60 stops suction. Since the cooking cavity may leak air, the negative pressure of the cooking cavity is slowly attenuated and the pressure is gradually increased after the air suction device 60 stops sucking air. Under a better sealing environment, the pressure rises by 2kp every 10 min. The decay rate after rising to-30 kp will reach a pressure loss of between 1 and 1.5kp per 10min relatively slowly.
In order to ensure that the pressure in the cooking chamber 1 can meet the first preset pressure value throughout the pickling phase. It is necessary to pump the cooking chamber 1 once at intervals. In order to achieve the above object, the present application also provides a third embodiment. Embodiment three of the cooking control method of the present application is different from embodiment one of the cooking control method of the present application in that air suction is performed a plurality of times. Specifically, in the third embodiment, the cooking control method includes: after the trigger signal is detected, the air extracting device 60 starts air extracting from the air extracting cavity 2 in response to the trigger signal; the following steps are circularly executed until the execution times are equal to the preset times: under a first preset condition, the float driving mechanism drives the float 40 to move from the air suction position to the sealing position; the air extracting device 60 stops extracting air; under a second preset condition, the float driving mechanism drives the float 40 to move from the sealing position to the air extracting position; the air extractor 60 starts to extract air, and under the condition that the execution times are equal to the preset times, the float driving mechanism drives the float 40 to move from the air extraction position to the sealing position, the air extractor 60 continues to extract air from the air extraction cavity 2 until the third preset condition is met, and the air extractor 60 stops extracting air. The structure can realize intermittent air extraction, so that the pressure intensity in the cooking cavity 1 can meet a first preset pressure intensity value as much as possible in the whole curing stage, and the cooking effect (curing effect and the like) is optimal.
Specifically, in the third embodiment, under the first preset condition, the float driving mechanism driving the float 40 to move from the suction position to the sealing position includes: detecting the pressure inside the cooking chamber 1; in the case that the pressure in the cooking cavity 1 is less than or equal to a first preset pressure value, the float driving mechanism drives the float 40 to move from the air suction position to the sealing position; under a second preset condition, the float driving mechanism driving the float 40 from the sealing position to the pumping position includes: in the case that the pressure in the cooking cavity 1 is greater than or equal to a third preset pressure value, the float driving mechanism drives the float 40 to move from the sealing position to the air extracting position, wherein the third preset pressure value is greater than the first preset pressure value; in the case where the third preset condition is satisfied, stopping the air extraction by the air extracting device 60 includes: the pressure of the air pumping cavity 2 is smaller than or equal to the second preset pressure value, and the air pumping device 60 stops pumping. The control method controls the movement of the float 40 by measuring the pressure in the cooking chamber 1 and the pumping chamber 2, so that the control result is more accurate and the cooking effect is better.
Since some cooking appliances do not have a measuring element for measuring pressure, in order to enable these cooking appliances without a load cell to have the pickling function described above, the present application also provides a fourth embodiment. The fourth embodiment of the cooking control method of the present application is different from the third embodiment of the cooking control method of the present application in the first preset condition and the second preset condition. Specifically, in the fourth embodiment, under the first preset condition, the float driving mechanism driving the float 40 to move from the suction position to the sealing position includes: recording the air extraction time length, and under the condition that the air extraction time length is greater than or equal to a first preset time interval, driving the floater 40 to move from the air extraction position to the sealing position by the floater driving mechanism, setting the air extraction time length to be zero, and starting to record the air extraction stopping time length; under a second preset condition, the float driving mechanism driving the float 40 from the sealing position to the pumping position includes: when the period of time for stopping pumping is greater than or equal to a second preset time interval, the float driving mechanism drives the float 40 to move from the sealing position to the pumping position, and the period of time for stopping pumping is set to be zero, wherein the second preset time interval is greater than the first preset time interval; in the case where the third preset condition is satisfied, stopping the air extraction by the air extracting device 60 includes: the air extraction time period is recorded, and the air extraction device 60 stops air extraction when the air extraction time period is equal to or longer than a third preset time interval. The above control method controls the movement of the float 40 by measuring the pumping time, and the control result is accurate, guaranteeing the cooking effect. The above-mentioned air extraction period refers to a time interval from a time point when the air extraction device 60 extracts air to a current time point.
The following description will be given by taking the example that the first preset time interval is 5 minutes, the second preset time interval is 10 minutes, the third preset time interval is 5 minutes, and the cycle number is 2 times:
after detecting the trigger signal, the air extractor 60 starts air extraction from the air extraction cavity 2 in response to the trigger signal, and the air extraction time period is recorded.
