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

[0003] Although the above design has a relatively simple structure, the single vacuum pump has a relatively short service life. For negative pressure cooking equipment, it 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, the present invention provides a control method for a cooking device, the cooking device comprising a cooking cavity, an air outlet valve connected to the cooking cavity, and a first vacuum pump and a second vacuum pump respectively connected to the air outlet valve, 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; determining a pressure difference between the pressure value and a preset pressure value; controlling the operating state of the first vacuum pump and the second vacuum pump according to a comparison result of the pressure difference and the preset pressure difference; when the cumulative cooking time is greater than or equal to the target time, controlling the first vacuum pump and / or the second vacuum pump that are in an on state to be turned off; 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 a cooking device, and the cooking device can be controlled by running the control method.

[0013] During this process, the first vacuum pump and the second vacuum pump can simultaneously extract gas from the cooking cavity through the outlet valve, that is, the two vacuum pumps jointly undertake the work of extracting gas from the cooking cavity. Compared with the design of a single vacuum pump, the technical solution of the present application can reduce the working time of each of the two vacuum pumps, thereby reducing the time they are in a wear state, thereby extending the service life of the vacuum pump.

[0014] When the service life of the vacuum pump used to extract the gas in the cooking cavity is extended, the service life of the cooking device is also extended.

[0015] In the above technical solution, the pressure difference is determined so as to compare the pressure difference with the preset pressure difference, thereby judging the size of the pressure difference, and then selecting whether the first vacuum pump and the second vacuum pump are to be operated simultaneously, or to be operated alone, or to be operated neither, according to the size of the pressure difference, so as to adapt to different usage scenarios.

[0016] In addition, the accumulated cooking time is compared with the target time to obtain a comparison result, thereby terminating the negative pressure cooking of the cooking device when the first vacuum pump and / or the second vacuum pump is in the on state and the negative pressure cooking time reaches the target time, thereby realizing automatic control of the cooking device.

[0017] 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.

[0018] In addition, the control method of the cooking device proposed in this application also has the following additional technical features.

[0019] In the above technical scheme, the preset pressure difference includes a first difference and a second difference, and the operating states of the first vacuum pump and the second vacuum pump are controlled according to the comparison result of the pressure difference and the preset pressure difference, specifically including: when the pressure difference is greater than the first difference, the first vacuum pump and the second vacuum pump are controlled to be turned on; when the pressure difference is less than the second difference, the first vacuum pump and the second vacuum pump are controlled to be turned off; when the pressure difference is between the first difference and the second difference, the first vacuum pump or the second vacuum pump is controlled to be turned on according to the comparison of the accumulated working time of the first vacuum pump and the second vacuum pump; wherein the first difference is greater than the second difference.

[0020] In this technical solution, if the pressure difference is greater than the first difference, it is considered that the difference between the pressure value in the cooking cavity and the preset pressure value is relatively large. The first vacuum pump and the second vacuum pump are controlled to open so that the gas in the cooking cavity can be extracted by both at the same time, thereby shortening the time required for the pressure in the cooking cavity to reach the preset pressure value, thereby shortening the cooking time of the cooking device.

[0021] When the pressure difference is less than the second difference, it is considered that the difference between the pressure value in the cooking cavity and the preset pressure value is small, that is, the pressure value in the cooking cavity is close to the preset pressure value. At this time, there is no need to control the vacuum pump to start and extract gas from the cooking cavity.

[0022] The setting of the second difference can reduce the starting frequency of the first vacuum pump and the second vacuum pump, thereby extending their service life.

[0023] When the pressure difference is between the first difference and the second difference, it is considered that the difference between the pressure value in the cooking cavity and the preset pressure value is not large, and the pressure in the cooking cavity can be adjusted by only controlling one of the first vacuum pump and the second vacuum pump to start. The accumulated working time of the first vacuum pump and the accumulated working time of the second vacuum pump are compared, so that the vacuum pump to be started is selected according to the comparison result.

[0024] In this process, screening conditions are set for starting the vacuum pump, so as to screen out reasonable vacuum pump starts to achieve the extraction of gas in the cooking chamber.

[0025] In the above technical solution, the first difference and the second difference are related to the target cooking program.

[0026] Specifically, different target cooking programs correspond to different first differences and second differences, so that the user can cook different types of ingredients through different target cooking programs, thereby ensuring the cooking effect.

[0027] In the above technical solution, the first vacuum pump and the second vacuum pump may be started synchronously or asynchronously.

[0028] In any of the above technical solutions, the first vacuum pump or the second vacuum pump is controlled to be turned on according to the comparison of the cumulative working time of the first vacuum pump and the second vacuum pump, specifically including: when the cumulative working time of the first vacuum pump is less than the cumulative working time of the second vacuum pump, the first vacuum pump is controlled to be turned on and the second vacuum pump is turned off; when the cumulative working time of the first vacuum pump is greater than or equal to the cumulative working time of the second vacuum pump, the first vacuum pump is controlled to be turned off and the second vacuum pump is turned on.

[0029] In this technical solution, by selecting a vacuum pump with a shorter cumulative working time to operate, the cumulative working time of the first vacuum pump and the second vacuum pump are made to be close to the same. Correspondingly, the wear conditions and lifespans of the two are similar, thereby reducing the situation where one of the first vacuum pump and the second vacuum pump is frequently used and the other is hardly used.

[0030] In one of the technical solutions, as the cooking device is continuously used, the first vacuum pump and the second vacuum pump can be operated alternately, so that the service life of the cooking device is limited by a single vacuum pump, thereby increasing the service life of the cooking device.

[0031] In any of the above technical solutions, 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.

[0032] In one of the technical solutions, 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 the preset pressure value.

[0033] In any of the above technical solutions, the control method further includes: updating the cooking parameters when the accumulated cooking time is less than the target time.

[0034] In this technical solution, the cooking parameters are updated so that the operation of the first vacuum pump and the second vacuum pump can be controlled according to the updated cooking parameters, thereby realizing automatic updating of the operating status of the first vacuum pump and the second vacuum pump, and at the same time, realizing automatic control of the target cooking program.

[0035] 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, and the heating device is used to heat the cooking cavity. 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.

[0036] In this embodiment, it is defined that the cooking device further includes a heating device, and the working timing of the heating device.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] In one embodiment, the heating device may be a heating plate or an electromagnetic heating system.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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, and a first vacuum pump and a second vacuum pump respectively connected to the air outlet valve, 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 determination unit, for determining a pressure difference between a pressure value and a preset pressure value; a comparison unit, for controlling an operating state of the first vacuum pump and the second vacuum pump according to a comparison result between the pressure difference and the preset pressure difference; a control unit, for controlling the first vacuum pump and / or the second vacuum pump in an on state to be turned off when the cumulative cooking time is greater than or equal to the target time; wherein the preset pressure value and the target time are related to the target cooking program.

In this process, the first vacuum pump and the second vacuum pump can simultaneously extract gas from the cooking cavity through the gas outlet valve, that is, the two vacuum pumps jointly undertake the extraction of gas from the cooking cavity. Compared with the design of a single vacuum pump, the technical solution of the present application can reduce the working time of each of the two vacuum pumps, thereby reducing the time they are in a wear state, thereby extending the service life of the vacuum pump.

[0120] 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;

[0121] Step 104, determining a pressure difference between the pressure value and a preset pressure value;

[0122] Step 106, controlling the operating states of the first vacuum pump and the second vacuum pump according to the comparison result between the pressure difference and the preset pressure difference;

[0123] Step 108: When the accumulated cooking time is greater than or equal to the target cooking time, the first vacuum pump and / or the second vacuum pump that are in an on state are controlled to be turned off.

[0124] Among them, the preset pressure value and target duration are related to the target cooking program.

[0125] The embodiment of the present application proposes a control method for a cooking device. By running the control method, the cooking device can be controlled.

[0126] During this process, the first vacuum pump and the second vacuum pump can simultaneously extract gas from the cooking chamber through the outlet valve, that is, the two vacuum pumps jointly undertake the work of extracting gas from the cooking chamber. Compared with the design of a single vacuum pump, the embodiment of the present application can reduce the working time of each of the two vacuum pumps, thereby reducing the time they are in a wear state, thereby extending the service life of the vacuum pump.

[0127] When the service life of the vacuum pump used to extract the gas in the cooking cavity is extended, the service life of the cooking device is also extended.

[0128] In the above embodiment, the pressure difference is determined so as to compare the pressure difference with the preset pressure difference, thereby judging the size of the pressure difference, and then selecting whether the first vacuum pump and the second vacuum pump are to be operated simultaneously, or to be operated alone, or to be operated neither, according to the size of the pressure difference, so as to adapt to different usage scenarios.

[0129] In addition, the accumulated cooking time is compared with the target time to obtain a comparison result, thereby terminating the negative pressure cooking of the cooking device when the first vacuum pump and / or the second vacuum pump is in the on state and the negative pressure cooking time reaches the target time, thereby realizing automatic control of the cooking device.

[0130] 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.

[0131] In the above embodiment, the preset pressure difference includes a first difference and a second difference, and the operating states of the first vacuum pump and the second vacuum pump are controlled according to the comparison result of the pressure difference and the preset pressure difference, specifically including: when the pressure difference is greater than the first difference, the first vacuum pump and the second vacuum pump are controlled to be turned on; when the pressure difference is less than the second difference, the first vacuum pump and the second vacuum pump are controlled to be turned off; when the pressure difference is between the first difference and the second difference, the first vacuum pump or the second vacuum pump is controlled to be turned on according to the comparison of the accumulated working time of the first vacuum pump and the second vacuum pump; wherein the first difference is greater than the second difference.

[0132] In this embodiment, if the pressure difference is greater than the first difference, it is considered that the difference between the pressure value in the cooking cavity and the preset pressure value is relatively large. The first vacuum pump and the second vacuum pump are controlled to be turned on so that the gas in the cooking cavity can be extracted by both at the same time, thereby shortening the time required for the pressure in the cooking cavity to reach the preset pressure value, thereby shortening the cooking time of the cooking device.

[0133] When the pressure difference is less than the second difference, it is considered that the difference between the pressure value in the cooking cavity and the preset pressure value is small, that is, the pressure value in the cooking cavity is close to the preset pressure value. At this time, there is no need to control the vacuum pump to start and extract gas from the cooking cavity.

[0134] The setting of the second difference can reduce the starting frequency of the first vacuum pump and the second vacuum pump, thereby extending their service life.

[0135] When the pressure difference is between the first difference and the second difference, it is considered that the difference between the pressure value in the cooking cavity and the preset pressure value is not large, and the pressure in the cooking cavity can be adjusted by only controlling one of the first vacuum pump and the second vacuum pump to start. The accumulated working time of the first vacuum pump and the accumulated working time of the second vacuum pump are compared, so that the vacuum pump to be started is selected according to the comparison result.

[0136] In this process, screening conditions are set for starting the vacuum pump, so as to screen out reasonable vacuum pump starts to achieve the extraction of gas in the cooking chamber.

[0137] In the above embodiment, the first difference and the second difference are related to the target cooking process.

[0138] Specifically, different target cooking programs correspond to different first differences and second differences, so that the user can cook different types of ingredients through different target cooking programs, thereby ensuring the cooking effect.

[0139] In the above embodiment, the first vacuum pump and the second vacuum pump may be started synchronously or asynchronously.

[0140] In any of the above embodiments, the first vacuum pump or the second vacuum pump is controlled to be turned on according to the comparison of the accumulated working time of the first vacuum pump and the second vacuum pump, specifically including: when the accumulated working time of the first vacuum pump is less than the accumulated working time of the second vacuum pump, the first vacuum pump is controlled to be turned on and the second vacuum pump is turned off; when the accumulated working time of the first vacuum pump is greater than or equal to the accumulated working time of the second vacuum pump, the first vacuum pump is controlled to be turned off and the second vacuum pump is controlled to be turned on.

[0141] In this embodiment, the vacuum pump with a shorter cumulative working time is selected for operation so that the cumulative working times of the first vacuum pump and the second vacuum pump are close to each other. Correspondingly, the wear conditions and lifespans of the two are similar, thereby reducing the situation where one of the first vacuum pump and the second vacuum pump is frequently used and the other is hardly used.

[0142] In one embodiment, the cumulative working time refers to the cumulative value of the usage time of each vacuum pump since the cooking device leaves the factory.

[0143] In one embodiment, as the cooking device is continuously used, the first vacuum pump and the second vacuum pump can be operated alternately, so that the service life of the cooking device is limited by a single vacuum pump, thereby increasing the service life of the cooking device.

[0144] In any of the above embodiments, 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.

[0145] 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.

[0146] In any of the above embodiments, the control method further includes: updating the cooking parameters when the accumulated cooking time is less than the target time.

[0147] In this embodiment, the cooking parameters are updated so that the operation of the first vacuum pump and the second vacuum pump are controlled according to the updated cooking parameters, thereby realizing automatic updating of the operating status of the first vacuum pump and the second vacuum pump, and at the same time, realizing automatic control of the target cooking program.

[0148] In any of the above embodiments, the cooking parameters also include a temperature value in the cooking cavity, the cooking equipment also includes a heating device, and the heating device is used to heat the cooking cavity. 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.

[0149] In this embodiment, it is defined that the cooking device further includes a heating device, and the working timing of the heating device.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0158] 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.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] 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.

[0164] 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.

[0165] In one embodiment, if Figure 2 As shown, the control method of the cooking device includes:

[0167] Step 204, close the air inlet valve, open the air outlet valve, and start heating;

[0169] Step 208, stop heating;

[0170] Step 210, start heating;

[0172] Step 214, start the first vacuum pump and the second vacuum pump;

[0174] Step 218, whether the accumulated working time of the first vacuum pump is less than the accumulated working time of the second vacuum pump, if the judgment result is yes, execute step 222, if the judgment result is no, execute step 224;

[0175] Step 220, turning off the first vacuum pump and the second vacuum pump;

[0176] Step 222, start the first vacuum pump and close the second vacuum pump;

[0177] Step 224, turning off the first vacuum pump and turning on the second vacuum pump;

[0178] Step 226, recording the accumulated working time of the first vacuum pump and the second vacuum pump;

[0179] Step 228, whether the cooking time is over, if the judgment result is yes, execute step 230, if the judgment result is no, execute step 206;

[0180] Step 230, turn off the first vacuum pump, the second vacuum pump, the heating, the air outlet valve, and open the air inlet valve;

[0181] Step 232, exit the negative pressure cooking program.

[0182] Among them, the cooking temperature is the target temperature value in this application, the set value is the preset pressure value in this application, the threshold 1 is the first difference in this application, the threshold 2 is the second difference in this application, and the cooking time is the target duration in this application.
