Description

Technical Field

[0001] The present invention relates to the technical field of cooking control, and in particular to a cooking device and a control method, device and readable storage medium thereof. Background Art

[0002] In the related technical solutions, negative pressure cooking equipment usually uses a single vacuum pump to create negative pressure, such as controlling the negative pressure by controlling the working time of the single vacuum pump.

[0003] However, although the above design has a relatively simple structure, the single vacuum pump has a short life under current operating conditions, and the negative pressure cooking equipment is greatly affected by the service life of the single vacuum pump, resulting in a relatively short service life of the negative pressure cooking equipment. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] To this end, a first aspect of the present invention is to provide a control method for a cooking device.

[0006] A second aspect of the present invention provides a control device for a cooking device.

[0007] A third aspect of the present invention is to provide another control device for a cooking device.

[0008] A fourth aspect of the present invention provides a readable storage medium.

[0009] A fifth aspect of the present invention provides a cooking device.

[0010] A sixth aspect of the present invention provides another cooking device.

[0011] In view of this, according to a first aspect of the present invention, there is provided a control method for a cooking device, the cooking device comprising a cooking cavity, an air outlet valve connected to the cooking cavity, a first vacuum pump connected to the air outlet valve, and a second vacuum pump connected to the first vacuum pump, the control method comprising: in response to a first input of a target cooking program, obtaining cooking parameters in the cooking cavity, the cooking parameters comprising a pressure value in the cooking cavity and a cumulative cooking time of the cooking device; controlling the first vacuum pump and the second vacuum pump to be turned on and off synchronously according to a first comparison result between the pressure value and a preset pressure value; and controlling the first vacuum pump and the second vacuum pump to be turned off synchronously according to a second comparison result between the cumulative cooking time and the target time when the first vacuum pump and the second vacuum pump are in an on state; wherein the preset pressure value and the target time are related to the target cooking program.

[0012] The technical solution of the present application proposes a control method for cooking equipment. By running the above control method, the synchronous control of the first vacuum pump and the second vacuum pump can be achieved, thereby extending the service life of the first vacuum pump and the second vacuum pump, and at the same time, extending the service life of the cooking equipment.

[0013] Specifically, when a single vacuum pump is used for negative pressure cooking, the working pressure of the single vacuum pump varies greatly from the time it is turned on to the time it reaches the set negative pressure. That is, the open-loop control air pressure fluctuation of the single vacuum pump is relatively large, which easily accelerates the wear of the single vacuum pump and reduces the service life of the single vacuum pump.

[0014] In the technical solution of the present application, since the first vacuum pump and the second vacuum pump are interconnected and connected to the air outlet valve of the cooking chamber, the pressure borne by the single vacuum pump in the relevant technical solution is shared by the first vacuum pump and the second vacuum pump. Obviously, at this time, the working pressure borne by the first vacuum pump and the second vacuum pump is reduced. Correspondingly, when open-loop control is performed, the air pressure fluctuation under the open-loop control of each vacuum pump becomes smaller, which slows down the wear rate of the first vacuum pump and the second vacuum pump, thereby extending the service life of the first vacuum pump and the second vacuum pump.

[0015] In addition, since the first vacuum pump and the second vacuum pump are started synchronously, the gas in the cooking cavity can be extracted at the same time during the negative pressure cooking process. Compared with the related technical solutions, the pressure of the gas extracted from the cooking cavity by the technical solution of the present application will be greater. Under the condition of achieving the same negative pressure effect in the cooking cavity, the vacuum pump series structure proposed in the present application can shorten the time to achieve the negative pressure effect, thereby shortening the time spent on negative pressure cooking.

[0016] In the above technical solution, the air outlet valve is connected to the cooking cavity, so it can realize gas exchange between the inside and outside of the cooking cavity. When the first vacuum pump and the second vacuum pump are turned on synchronously, the gas in the cooking cavity can be extracted through the air outlet valve, thereby achieving the effect of negative pressure cooking.

[0017] In one of the technical solutions, the first vacuum pump and the second vacuum pump are controlled to be turned on and off synchronously according to the first comparison result, so as to control the negative pressure in the cooking cavity.

[0018] At the same time, if the first vacuum pump and the second vacuum pump are in the on state, the accumulated cooking time is compared with the target time to obtain a second comparison result, thereby ending the negative pressure cooking of the cooking device when the negative pressure cooking time reaches the target time.

[0019] In the above technical solution, the target time and preset pressure value are related to the target cooking program. Therefore, the corresponding target time and preset pressure value can be set according to different cooking programs to meet the negative pressure cooking requirements of different ingredients and ensure the negative pressure cooking effect.

[0020] In addition, the control method of the cooking device proposed in this application also has the following additional technical features.

[0021] In the above technical scheme, the first vacuum pump and the second vacuum pump are controlled to be turned on and off synchronously according to a first comparison result between the pressure value and the preset pressure value, specifically including: when the pressure value is greater than the preset pressure value, the first vacuum pump and the second vacuum pump are controlled to be turned on synchronously; when the pressure value is less than or equal to the preset pressure value, the first vacuum pump and the second vacuum pump are controlled to be turned off synchronously.

[0022] In this technical solution, since the technical solution of the present application utilizes negative pressure to cook food, it is necessary to maintain the pressure in the cooking cavity at a relatively low level, such as maintaining it at a preset pressure value. Therefore, when the pressure value in the cooking cavity is greater than the preset pressure value, it is considered that the pressure in the cooking cavity is too high, and it is necessary to control the first vacuum pump and the second vacuum pump to be turned on synchronously to extract the gas in the cooking cavity. Conversely, when the pressure value in the cooking cavity is less than or equal to the preset pressure value, the first vacuum pump and the second vacuum pump are controlled to be turned off synchronously so that the pressure value in the cooking cavity can be maintained at the preset pressure value, thereby ensuring the cooking effect of the cooking device.

[0023] In any of the above technical solutions, the first vacuum pump and the second vacuum pump are controlled to be turned off synchronously according to the second comparison result between the cumulative cooking time and the target time, specifically including: when the cumulative cooking time is less than the target time, the cooking parameters are updated; when the cumulative cooking time is greater than or equal to the target time, the first vacuum pump and the second vacuum pump are controlled to be turned off synchronously.

[0024] In this technical solution, a target duration is set so that the target duration is used as a determination condition for the cooking device to end negative pressure cooking, thereby realizing automatic cooking control of the cooking device.

[0025] In the above technical solution, the first vacuum pump and the second vacuum pump are controlled to be shut down synchronously to avoid the situation where the first vacuum pump and the second vacuum pump are still running at the end of cooking, causing confusion in the control logic of the cooking equipment and failing to automatically end the operation.

[0026] In one of the technical solutions, when the accumulated cooking time is greater than or equal to the target time, the working status of the first vacuum pump and the second vacuum pump are obtained, and when the first vacuum pump and the second vacuum pump are in working status, the first vacuum pump and the second vacuum pump are synchronously shut down.

[0027] In any of the above technical solutions, the cooking parameters also include the temperature value in the cooking cavity, the cooking equipment also includes a heating device, the heating device is used to heat the cooking cavity, and before controlling the first vacuum pump and the second vacuum pump to be synchronously turned on and off according to the first comparison result between the pressure value and the preset pressure value, the control method also includes: opening the air outlet valve; when the temperature value is less than the target temperature value, controlling the heating device to start running; when the temperature value is greater than or equal to the target temperature value, controlling the heating device to stop running.

[0028] In this technical solution, it is defined that the cooking device also includes a heating device, and the working timing of the heating device.

[0029] By limiting the opening of the air outlet valve, the temperature value in the cooking cavity is compared with the target temperature value, thereby controlling the operation of the heating device, so that during the operation of the heating device, the gas in the cooking cavity can expand due to the heat and be discharged from the cooking cavity by the air outlet valve. In this process, the probability of the problem of excessive pressure in the cooking cavity during the cooking process of the cooking device can be reduced.

[0030] In addition, when the heating device heats the cooking cavity, the gas in the cooking cavity expands due to the heat and is discharged from the cooking cavity, reducing the amount of gas to be transported by the first vacuum pump and the second vacuum pump, thereby shortening the time spent on cooking by the cooking device.

[0031] In one of the technical solutions, after the air outlet valve is opened, the temperature value in the cooking cavity is obtained, and the temperature value in the cooking cavity is compared with the target temperature value, so as to control the operating state of the heating device according to the comparison result.

[0032] In the above technical solution, when the temperature in the cooking cavity is lower than the target temperature value, the heating device can be controlled to heat the cooking cavity, or when the temperature in the cooking cavity is higher than the target temperature value, the heating device can be controlled to stop heating so as to maintain the temperature of the cooking cavity at the target temperature value.

[0033] In any of the above technical solutions, when the heating device is in operation, the control method further includes: when the accumulated cooking time is greater than or equal to the target time, controlling the heating device to stop operating.

[0034] In this technical solution, as can be seen above, the purpose of setting the target time is to achieve automatic control of the cooking equipment. If the cumulative cooking time reaches the target time and the heating device is still in operation, it is necessary to control the heating device to stop running in order to ensure the safe use of the cooking equipment.

[0035] In one of the technical solutions, when the accumulated cooking time is greater than or equal to the target time, the working state of the heating device is obtained, and when the heating device is in the operating state, the heating device is controlled to stop operating.

[0036] In one of the technical solutions, the heating device can be a heating plate or an electromagnetic heating system.

[0037] Specifically, the electromagnetic heating system includes an electromagnetic heating coil, wherein the electromagnetic heating coil generates an electromagnetic field, so that an eddy current is formed in the cooking cavity to achieve heating of the cooking cavity.

[0038] In any of the above technical solutions, the control method further includes: when the accumulated cooking time is greater than or equal to the target time, closing the air outlet valve.

[0039] In this technical solution, the air outlet valve is closed to reduce the amount of dust and other particles in the environment entering the cooking cavity through the air outlet valve after the cooking device finishes cooking, thereby reducing the impact on the hygiene and safety of the cooking cavity.

[0040] In addition, by controlling the air outlet valve to close, when the cooking chamber is opened, the pressure on the side of the first vacuum pump close to the air outlet valve will not increase suddenly, thereby reducing the probability of damage to the first vacuum pump and ensuring the reliability of the cooking device.

[0041] In any of the above technical solutions, the cooking device also includes an air inlet valve connected to the cooking cavity. After responding to the first input of the target cooking program, the control method also includes: closing the air inlet valve, and opening the air outlet valve when the cumulative cooking time is greater than or equal to the target time.

[0042] In this technical solution, an air intake valve is provided so that in the initial stage of cooking of the cooking device, the air intake valve is closed to seal the cooking cavity, thereby preventing air from entering the cooking cavity through the air intake valve when the first vacuum pump and the second vacuum pump are turned on, thereby preventing a negative pressure cooking environment from being formed.

[0043] At the same time, when the cumulative cooking time reaches the target time, the air inlet valve is opened to allow gas outside the cooking cavity to enter the cooking cavity, so that the air pressure in the cooking cavity is the same as the ambient air pressure, making it convenient for the user to open the cooking cavity and take out the cooked ingredients.

[0044] According to a second aspect of the present invention, there is provided a control device for a cooking device, the cooking device comprising a cooking cavity, an air outlet valve connected to the cooking cavity, a first vacuum pump connected to the air outlet valve, and a second vacuum pump connected to the first vacuum pump, the control device comprising: an acquisition unit, for acquiring cooking parameters in the cooking cavity in response to a first input of a target cooking program, the cooking parameters comprising a pressure value in the cooking cavity and a cumulative cooking time of the cooking device; a first control unit, for controlling a first vacuum pump and a second vacuum pump to be turned on and off synchronously according to a first comparison result between the pressure value and a preset pressure value; a second control unit, for controlling a first vacuum pump and a second vacuum pump to be turned off synchronously according to a second comparison result between the cumulative cooking time and the target time when the first vacuum pump and the second vacuum pump are in an on state; wherein the preset pressure value and the target time are related to the target cooking program.

[0045] The technical solution of the present application proposes a control device for cooking equipment, which can realize synchronous control of a first vacuum pump and a second vacuum pump, thereby extending the service life of the first vacuum pump and the second vacuum pump, and at the same time, also extending the service life of the cooking equipment.

[0046] Specifically, when a single vacuum pump is used for negative pressure cooking, the working pressure of the single vacuum pump varies greatly from the time it is turned on to the time it reaches the set negative pressure. That is, the open-loop control air pressure fluctuation of the single vacuum pump is relatively large, which easily accelerates the wear of the single vacuum pump and reduces the service life of the single vacuum pump.

[0047] In the technical solution of the present application, since the first vacuum pump and the second vacuum pump are interconnected and connected to the air outlet valve of the cooking chamber, the pressure borne by the single vacuum pump in the relevant technical solution is shared by the first vacuum pump and the second vacuum pump. Obviously, at this time, the working pressure borne by the first vacuum pump and the second vacuum pump is reduced. Correspondingly, when open-loop control is performed, the air pressure fluctuation under the open-loop control of each vacuum pump becomes smaller, which slows down the wear rate of the first vacuum pump and the second vacuum pump, thereby extending the service life of the first vacuum pump and the second vacuum pump.

[0048] In addition, since the first vacuum pump and the second vacuum pump are started synchronously, the gas in the cooking cavity can be extracted at the same time during the negative pressure cooking process. Compared with the related technical solutions, the pressure of the gas extracted from the cooking cavity by the technical solution of the present application will be greater. Under the condition of achieving the same negative pressure effect in the cooking cavity, the vacuum pump series structure proposed in the present application can shorten the time to achieve the negative pressure effect, thereby shortening the time spent on negative pressure cooking.

[0049] In the above technical solution, the air outlet valve is connected to the cooking cavity, so it can realize gas exchange between the inside and outside of the cooking cavity. When the first vacuum pump and the second vacuum pump are turned on synchronously, the gas in the cooking cavity can be extracted through the air outlet valve, thereby achieving the effect of negative pressure cooking.

[0050] In one of the technical solutions, the first vacuum pump and the second vacuum pump are controlled to be turned on and off synchronously according to the first comparison result, so as to control the negative pressure in the cooking cavity.

[0051] At the same time, if the first vacuum pump and the second vacuum pump are in the on state, the accumulated cooking time is compared with the target time to obtain a second comparison result, thereby ending the negative pressure cooking of the cooking device when the negative pressure cooking time reaches the target time.

[0052] In the above technical solution, the target time and preset pressure value are related to the target cooking program. Therefore, the corresponding target time and preset pressure value can be set according to different cooking programs to meet the negative pressure cooking requirements of different ingredients and ensure the negative pressure cooking effect.

[0053] In addition, the control device of the cooking equipment proposed in this application also has the following additional technical features.

[0054] In the above technical solution, the first control unit is specifically used to control the first vacuum pump and the second vacuum pump to start synchronously when the pressure value is greater than the preset pressure value; and to control the first vacuum pump and the second vacuum pump to shut down synchronously when the pressure value is less than or equal to the preset pressure value.

[0055] In this technical solution, since the technical solution of the present application utilizes negative pressure to cook food, it is necessary to maintain the pressure in the cooking cavity at a relatively low level, such as maintaining it at a preset pressure value.

[0056] In any of the above technical solutions, the second control unit is specifically used to update the cooking parameters when the cumulative cooking time is less than the target time; and to control the first vacuum pump and the second vacuum pump to shut down synchronously when the cumulative cooking time is greater than or equal to the target time.

[0057] In this technical solution, a target duration is set so that the target duration is used as a determination condition for the cooking device to end negative pressure cooking, thereby realizing automatic cooking control of the cooking device.

[0058] In the above technical solution, the first vacuum pump and the second vacuum pump are controlled to be shut down synchronously to avoid the situation where the first vacuum pump and the second vacuum pump are still running at the end of cooking, causing confusion in the control logic of the cooking equipment and failing to automatically end the operation.

[0060] In any of the above technical solutions, the cooking parameters also include the temperature value in the cooking cavity, and the cooking equipment also includes a heating device, which is used to heat the cooking cavity. Before controlling the first vacuum pump and the second vacuum pump to be synchronously turned on and off according to a first comparison result between the pressure value and the preset pressure value, the first control unit is also used to open the air outlet valve; when the temperature value is less than the target temperature value, the heating device is controlled to start running; when the temperature value is greater than or equal to the target temperature value, the heating device is controlled to stop running.

DETAILED DESCRIPTION

[0092] In order to more clearly understand the above aspects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0093] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0094] In one embodiment of the present application, Figure 1 , Figure 5 and Figure 6 As shown, a control method for a cooking device is provided, the cooking device comprising a cooking cavity 502, an air outlet valve 504 connected to the cooking cavity 502, a first vacuum pump 506 connected to the air outlet valve 504, and a second vacuum pump 508 connected to the first vacuum pump 506, the control method comprising:

[0095] Step 102, in response to the first input of the target cooking program, obtaining cooking parameters in the cooking cavity, the cooking parameters including the pressure value in the cooking cavity and the accumulated cooking time of the cooking device;

[0096] Step 104, controlling the first vacuum pump and the second vacuum pump to be synchronously turned on and off according to a first comparison result between the pressure value and the preset pressure value;

[0097] Step 106 , when the first vacuum pump and the second vacuum pump are in the on state, the first vacuum pump and the second vacuum pump are controlled to be turned off synchronously according to the second comparison result between the accumulated cooking time and the target cooking time.

[0098] Among them, the preset pressure value and target duration are related to the target cooking program.

[0099] An embodiment of the present application proposes a control method for a cooking device. By running the above control method, synchronous control of a first vacuum pump and a second vacuum pump can be achieved, thereby extending the service life of the first vacuum pump and the second vacuum pump, and at the same time, extending the service life of the cooking device.

[0100] Specifically, when a single vacuum pump is used for negative pressure cooking, the working pressure of the single vacuum pump varies greatly from the time it is turned on to the time it reaches the set negative pressure. That is, the open-loop control air pressure fluctuation of the single vacuum pump is relatively large, which easily accelerates the wear of the single vacuum pump and reduces the service life of the single vacuum pump.

[0101] In the embodiments of the present application, since the first vacuum pump and the second vacuum pump are interconnected and connected to the air outlet valve of the cooking chamber, the pressure borne by the single vacuum pump in the relevant embodiments is shared by the first vacuum pump and the second vacuum pump. Obviously, at this time, the working pressure borne by the first vacuum pump and the second vacuum pump is reduced. Correspondingly, when open-loop control is performed, the air pressure fluctuation under the open-loop control of each vacuum pump becomes smaller, which slows down the wear rate of the first vacuum pump and the second vacuum pump, thereby extending the service life of the first vacuum pump and the second vacuum pump.

[0102] In addition, since the first vacuum pump and the second vacuum pump are started synchronously, the gas in the cooking cavity can be extracted at the same time during the negative pressure cooking process. Compared with the related embodiments, the pressure of the gas extracted from the cooking cavity in the embodiment of the present application will be greater. Under the condition of achieving the same negative pressure effect in the cooking cavity, the vacuum pump series structure proposed in the present application can shorten the time to achieve the negative pressure effect, thereby shortening the time spent on negative pressure cooking.

[0103] In the above embodiment, the air outlet valve is connected to the cooking cavity, so it can realize gas exchange between the inside and outside of the cooking cavity. When the first vacuum pump and the second vacuum pump are turned on synchronously, the gas in the cooking cavity can be extracted through the air outlet valve, thereby achieving the effect of negative pressure cooking.

[0104] In one of the embodiments, the first vacuum pump and the second vacuum pump are controlled to be turned on and off synchronously according to the first comparison result, so as to control the negative pressure in the cooking cavity.

[0105] At the same time, if the first vacuum pump and the second vacuum pump are in the on state, the accumulated cooking time is compared with the target time to obtain a second comparison result, thereby ending the negative pressure cooking of the cooking device when the negative pressure cooking time reaches the target time.

[0106] In the above embodiment, the target time and the preset pressure value are related to the target cooking program. Therefore, the corresponding target time and the preset pressure value can be set according to different cooking programs to meet the negative pressure cooking requirements of different ingredients and ensure the negative pressure cooking effect.

[0107] In one embodiment, the accumulated cooking time can be understood as the accumulated time after the temperature value of the cooking cavity is greater than or equal to the target temperature value and the pressure value in the cooking cavity is less than the preset pressure value for the first time.

[0108] In one embodiment, the accumulated cooking time can be understood as the duration during which the temperature value of the cooking cavity is greater than or equal to the target temperature value and the pressure value in the cooking cavity remains less than a preset pressure value.

[0109] In the above embodiment, the first vacuum pump and the second vacuum pump are controlled to be turned on and off synchronously according to a first comparison result between the pressure value and the preset pressure value, specifically including: when the pressure value is greater than the preset pressure value, the first vacuum pump and the second vacuum pump are controlled to be turned on synchronously; when the pressure value is less than or equal to the preset pressure value, the first vacuum pump and the second vacuum pump are controlled to be turned off synchronously.

[0110] In this embodiment, since the embodiment of the present application utilizes negative pressure to cook food, it is necessary to maintain the pressure in the cooking cavity at a relatively low level, such as maintaining it at a preset pressure value. Therefore, when the pressure value in the cooking cavity is greater than the preset pressure value, it is considered that the pressure in the cooking cavity is too high, and it is necessary to control the first vacuum pump and the second vacuum pump to be turned on synchronously to extract the gas in the cooking cavity. Conversely, when the pressure value in the cooking cavity is less than or equal to the preset pressure value, the first vacuum pump and the second vacuum pump are controlled to be turned off synchronously so that the pressure value in the cooking cavity can be maintained at the preset pressure value, thereby ensuring the cooking effect of the cooking device.

[0111] In any of the above embodiments, the first vacuum pump and the second vacuum pump are controlled to be turned off synchronously according to the second comparison result between the cumulative cooking time and the target time, specifically including: when the cumulative cooking time is less than the target time, the cooking parameters are updated; when the cumulative cooking time is greater than or equal to the target time, the first vacuum pump and the second vacuum pump are controlled to be turned off synchronously.

[0112] In this embodiment, the target time length is set so that the target time length is used as a determination condition for the cooking device to end negative pressure cooking, thereby realizing automatic cooking control of the cooking device.

[0113] In the above embodiment, the first vacuum pump and the second vacuum pump are controlled to be turned off synchronously to avoid the situation where the first vacuum pump and the second vacuum pump are still running at the end of cooking, causing confusion in the control logic of the cooking device and failing to automatically end the operation.

[0114] In one of the embodiments, when the accumulated cooking time is greater than or equal to the target time, the working status of the first vacuum pump and the second vacuum pump are obtained, and when the first vacuum pump and the second vacuum pump are in working state, the first vacuum pump and the second vacuum pump are synchronously shut down.

[0115] In any of the above embodiments, the cooking parameters also include a temperature value in the cooking cavity, and the cooking equipment also includes a heating device, which is used to heat the cooking cavity. Before controlling the first vacuum pump and the second vacuum pump to be synchronously turned on and off according to a first comparison result between the pressure value and the preset pressure value, the control method also includes: opening the air outlet valve; when the temperature value is less than the target temperature value, controlling the heating device to start running; when the temperature value is greater than or equal to the target temperature value, controlling the heating device to stop running.

[0116] In this embodiment, it is defined that the cooking device further includes a heating device, and the working timing of the heating device.

[0117] By limiting the opening of the air outlet valve, the temperature value in the cooking cavity is compared with the target temperature value, thereby controlling the operation of the heating device, so that during the operation of the heating device, the gas in the cooking cavity can expand due to the heat and be discharged from the cooking cavity by the air outlet valve. In this process, the probability of the problem of excessive pressure in the cooking cavity during the cooking process of the cooking device can be reduced.

[0118] In addition, when the heating device heats the cooking cavity, the gas in the cooking cavity expands due to the heat and is discharged from the cooking cavity, reducing the amount of gas to be transported by the first vacuum pump and the second vacuum pump, thereby shortening the time spent on cooking by the cooking device.

[0119] In one of the embodiments, after the air outlet valve is opened, the temperature value in the cooking cavity is obtained, and the temperature value in the cooking cavity is compared with the target temperature value, so that the operating state of the heating device is controlled according to the comparison result.

[0120] In the above embodiment, when the temperature in the cooking cavity is lower than the target temperature value, the heating device can be controlled to heat the cooking cavity, or when the temperature in the cooking cavity is higher than the target temperature value, the heating device can be controlled to stop heating so as to maintain the temperature of the cooking cavity at the target temperature value.

[0121] In any of the above embodiments, when the heating device is in operation, the control method further includes: when the accumulated cooking time is greater than or equal to the target cooking time, controlling the heating device to stop operating.

[0122] In this embodiment, as can be seen above, the purpose of setting the target time is to achieve automatic control of the cooking equipment. If the cumulative cooking time reaches the target time and the heating device is still in operation, it is necessary to control the heating device to stop running in order to ensure the safe use of the cooking equipment.

[0123] In one of the embodiments, when the accumulated cooking time is greater than or equal to the target time, the working state of the heating device is obtained, and when the heating device is in the operating state, the heating device is controlled to stop operating.

[0124] In one embodiment, the heating device can be a heating plate or an electromagnetic heating system.

[0125] Specifically, the electromagnetic heating system includes an electromagnetic heating coil, wherein the electromagnetic heating coil generates an electromagnetic field, so that an eddy current is formed in the cooking cavity to achieve heating of the cooking cavity.

[0126] In any of the above embodiments, the control method further includes: when the accumulated cooking time is greater than or equal to the target time, closing the gas outlet valve.

[0127] In this embodiment, the air outlet valve is closed to reduce the amount of dust and other particles in the environment entering the cooking cavity through the air outlet valve after the cooking device finishes cooking, thereby reducing the impact on the hygiene and safety of the cooking cavity.

[0128] In addition, by controlling the air outlet valve to close, when the cooking chamber is opened, the pressure on the side of the first vacuum pump close to the air outlet valve will not increase suddenly, thereby reducing the probability of damage to the first vacuum pump and ensuring the reliability of the cooking device.

[0129] In any of the above embodiments, the cooking device also includes an air inlet valve connected to the cooking cavity. After responding to a first input of a target cooking program, the control method also includes: closing the air inlet valve, and opening the air outlet valve when the accumulated cooking time is greater than or equal to the target time.

[0130] In this embodiment, an air intake valve is provided so that at the initial stage of cooking of the cooking device, the air intake valve is closed to seal the cooking cavity, thereby preventing air from entering the cooking cavity through the air intake valve when the first vacuum pump and the second vacuum pump are turned on, thereby preventing a negative pressure cooking environment from being formed.

[0131] At the same time, when the cumulative cooking time reaches the target time, the air inlet valve is opened to allow gas outside the cooking cavity to enter the cooking cavity, so that the air pressure in the cooking cavity is the same as the ambient air pressure, making it convenient for the user to open the cooking cavity and take out the cooked ingredients.

[0132] In one embodiment, if Figure 2 As shown, the control method of the cooking device includes:

[0133] Step 202, negative pressure cooking program starts;

[0134] Step 204, close the air inlet valve, open the air outlet valve, and start heating;

[0135] Step 206, whether the temperature reaches the cooking temperature, if the judgment result is yes, execute step 208, if the judgment result is no, execute step 210;

[0136] Step 208, stop heating;

[0137] Step 210, start heating;

[0138] Step 212, whether the air pressure reaches the set value, if the judgment result is yes, execute step 214, if the judgment result is no, execute step 216;

[0139] Step 214, turning off the first vacuum pump and the second vacuum pump;

[0140] Step 216, start the first vacuum pump and the second vacuum pump;

[0141] Step 218, whether the cooking time is over, if the judgment result is yes, execute step 220, if the judgment result is no, execute step 206;

[0142] Step 220, turning off the first vacuum pump and the second vacuum pump, turning off the heating, closing the air outlet valve and opening the air inlet valve;

[0143] Step 222, the negative pressure cooking process ends.

[0144] Among them, the cooking temperature is the target temperature value in this application, the set value is the preset pressure value in this application, and the cooking time is the target duration in this application.

[0145] In one embodiment, if Figure 3As shown, the present invention provides a control device 300 for a cooking device, the cooking device comprising a cooking cavity, an air outlet valve connected to the cooking cavity, a first vacuum pump connected to the air outlet valve, and a second vacuum pump connected to the first vacuum pump, the control device comprising: an acquisition unit 302, for acquiring cooking parameters in the cooking cavity in response to a first input of a target cooking program, the cooking parameters comprising a pressure value in the cooking cavity and a cumulative cooking time of the cooking device; a first control unit 304, for controlling the first vacuum pump and the second vacuum pump to be turned on and off synchronously according to a first comparison result between the pressure value and a preset pressure value; a second control unit 306, for controlling the first vacuum pump and the second vacuum pump to be turned off synchronously according to a second comparison result between the cumulative cooking time and the target time when the first vacuum pump and the second vacuum pump are in an on state; wherein the preset pressure value and the target time are related to the target cooking program.

[0146] The embodiment of the present application proposes a control device 300 for a cooking device, which can realize synchronous control of a first vacuum pump and a second vacuum pump, thereby extending the service life of the first vacuum pump and the second vacuum pump, and at the same time, also extending the service life of the cooking device.

[0147] Specifically, when a single vacuum pump is used for negative pressure cooking, the working pressure of the single vacuum pump varies greatly from the time it is turned on to the time it reaches the set negative pressure. That is, the open-loop control air pressure fluctuation of the single vacuum pump is relatively large, which easily accelerates the wear of the single vacuum pump and reduces the service life of the single vacuum pump.

[0148] In the embodiments of the present application, since the first vacuum pump and the second vacuum pump are interconnected and connected to the air outlet valve of the cooking chamber, the pressure borne by the single vacuum pump in the relevant embodiments is shared by the first vacuum pump and the second vacuum pump. Obviously, at this time, the working pressure borne by the first vacuum pump and the second vacuum pump is reduced. Correspondingly, when open-loop control is performed, the air pressure fluctuation under the open-loop control of each vacuum pump becomes smaller, which slows down the wear rate of the first vacuum pump and the second vacuum pump, thereby extending the service life of the first vacuum pump and the second vacuum pump.

[0149] In addition, since the first vacuum pump and the second vacuum pump are started synchronously, the gas in the cooking cavity can be extracted at the same time during the negative pressure cooking process. Compared with the related embodiments, the pressure of the gas extracted from the cooking cavity in the embodiment of the present application will be greater. Under the condition of achieving the same negative pressure effect in the cooking cavity, the vacuum pump series structure proposed in the present application can shorten the time to achieve the negative pressure effect, thereby shortening the time spent on negative pressure cooking.

[0150] In the above embodiment, the air outlet valve is connected to the cooking cavity, so it can realize gas exchange between the inside and outside of the cooking cavity. When the first vacuum pump and the second vacuum pump are turned on synchronously, the gas in the cooking cavity can be extracted through the air outlet valve, thereby achieving the effect of negative pressure cooking.

[0151] In one of the embodiments, the first vacuum pump and the second vacuum pump are controlled to be turned on and off synchronously according to the first comparison result, so as to control the negative pressure in the cooking cavity.

[0152] At the same time, if the first vacuum pump and the second vacuum pump are in the on state, the accumulated cooking time is compared with the target time to obtain a second comparison result, thereby ending the negative pressure cooking of the cooking device when the negative pressure cooking time reaches the target time.

[0153] In the above embodiment, the target time and the preset pressure value are related to the target cooking program. Therefore, the corresponding target time and the preset pressure value can be set according to different cooking programs to meet the negative pressure cooking requirements of different ingredients and ensure the negative pressure cooking effect.

[0154] In the above embodiment, the first control unit 304 is specifically used to control the first vacuum pump and the second vacuum pump to start synchronously when the pressure value is greater than the preset pressure value; and to control the first vacuum pump and the second vacuum pump to shut down synchronously when the pressure value is less than or equal to the preset pressure value.

[0155] In this embodiment, since the embodiment of the present application utilizes negative pressure to cook food, it is necessary to maintain the pressure in the cooking cavity at a relatively low level, such as maintaining it at a preset pressure value. Therefore, when the pressure value in the cooking cavity is greater than the preset pressure value, it is considered that the pressure in the cooking cavity is too high, and it is necessary to control the first vacuum pump and the second vacuum pump to be turned on synchronously to extract the gas in the cooking cavity. Conversely, when the pressure value in the cooking cavity is less than or equal to the preset pressure value, the first vacuum pump and the second vacuum pump are controlled to be turned off synchronously so that the pressure value in the cooking cavity can be maintained at the preset pressure value, thereby ensuring the cooking effect of the cooking device.

[0156] In any of the above embodiments, the second control unit 306 is specifically used to update the cooking parameters when the cumulative cooking time is less than the target time; and to control the first vacuum pump and the second vacuum pump to shut down synchronously when the cumulative cooking time is greater than or equal to the target time.

[0157] In this embodiment, the target time length is set so that the target time length is used as a determination condition for the cooking device to end negative pressure cooking, thereby realizing automatic cooking control of the cooking device.

[0158] In the above embodiment, the first vacuum pump and the second vacuum pump are controlled to be turned off synchronously to avoid the situation where the first vacuum pump and the second vacuum pump are still running at the end of cooking, causing confusion in the control logic of the cooking device and failing to automatically end the operation.

[0159] In one of the embodiments, when the accumulated cooking time is greater than or equal to the target time, the working status of the first vacuum pump and the second vacuum pump are obtained, and when the first vacuum pump and the second vacuum pump are in working state, the first vacuum pump and the second vacuum pump are synchronously shut down.

[0160] In any of the above embodiments, the cooking parameters also include a temperature value in the cooking cavity, and the cooking equipment also includes a heating device, which is used to heat the cooking cavity. Before controlling the first vacuum pump and the second vacuum pump to be synchronously turned on and off according to a first comparison result between the pressure value and the preset pressure value, the first control unit 304 is also used to open the air outlet valve; when the temperature value is less than the target temperature value, the heating device is controlled to start running; when the temperature value is greater than or equal to the target temperature value, the heating device is controlled to stop running.

[0161] In this embodiment, it is defined that the cooking device further includes a heating device, and the working timing of the heating device.

In this process, the probability of the problem of excessive pressure in the cooking cavity during the cooking process of the cooking device can be reduced.

[0163] In addition, when the heating device heats the cooking cavity, the gas in the cooking cavity expands due to the heat and is discharged from the cooking cavity, reducing the amount of gas to be transported by the first vacuum pump and the second vacuum pump, thereby shortening the time spent on cooking by the cooking device.

[0164] In one of the embodiments, after the air outlet valve is opened, the temperature value in the cooking cavity is obtained, and the temperature value in the cooking cavity is compared with the target temperature value, so that the operating state of the heating device is controlled according to the comparison result.

[0165] In the above embodiment, when the temperature in the cooking cavity is lower than the target temperature value, the heating device can be controlled to heat the cooking cavity, or when the temperature in the cooking cavity is higher than the target temperature value, the heating device can be controlled to stop heating so as to maintain the temperature of the cooking cavity at the target temperature value.

[0167] In this embodiment, as can be seen above, the purpose of setting the target time is to achieve automatic control of the cooking equipment. If the cumulative cooking time reaches the target time and the heating device is still in operation, it is necessary to control the heating device to stop running in order to ensure the safe use of the cooking equipment.

[0171] In any of the above embodiments, the second control unit 306 is further configured to close the gas outlet valve when the accumulated cooking time is greater than or equal to the target cooking time.

[0172] In this embodiment, the air outlet valve is closed to reduce the amount of dust and other particles in the environment entering the cooking cavity through the air outlet valve after the cooking device finishes cooking, thereby reducing the impact on the hygiene and safety of the cooking cavity.

[0173] In addition, by controlling the air outlet valve to close, when the cooking chamber is opened, the pressure on the side of the first vacuum pump close to the air outlet valve will not increase suddenly, thereby reducing the probability of damage to the first vacuum pump and ensuring the reliability of the cooking device.

[0174] In any of the above embodiments, the cooking device also includes an air inlet valve connected to the cooking cavity, and the first control unit 304 is further used to close the air inlet valve and open the air outlet valve when the accumulated cooking time is greater than or equal to the target time.

[0181] An embodiment of the present application proposes a cooking device that can achieve synchronous control of a first vacuum pump and a second vacuum pump, thereby extending the service life of the first vacuum pump and the second vacuum pump, and at the same time, also extending the service life of the cooking device.

[0182] Specifically, when a single vacuum pump is used for negative pressure cooking, the working pressure of the single vacuum pump varies greatly from the time it is turned on to the time it reaches the set negative pressure. That is, the open-loop control air pressure fluctuation of the single vacuum pump is relatively large, which easily accelerates the wear of the single vacuum pump and reduces the service life of the single vacuum pump.
