Description

Technical Field

[0001] The present application relates to the field of smart furniture, and in particular to a control method, device and cooking equipment for preventing pressure overshoot in cooking equipment. Background Art

[0002] The electric pressure cookers, pressure cookers and pressure stews currently on the market often have inherent thermal inertia characteristics of the heating components (such as heating wires and heating plates). Even after stopping or reducing the heating power, the pressure in the pot will continue to rise sharply, causing the pressure value to exceed the expected control range. This phenomenon is particularly significant when the amount of food is small or the contact between the inner pot and the heating plate is poor. This uncontrollable pressure increase can easily cause the food (especially soups and porridge) to overflow when the pressure is subsequently released through the exhaust system. In severe cases, it may even trigger the safety pressure relief mechanism, posing a potential threat to the user's safety.

[0003] The previous solution tried to install a bottom temperature sensor to predict and adjust the heating power in order to curb the excessive pressure rise before the pressure switch was activated. However, this method is limited by the hysteresis effect of the sensor response and the inherent deviation between the bottom temperature and the actual pressure in the pot. The effect of controlling pressure overshoot is not ideal, and it is difficult to achieve the purpose of accurately managing the pressure in the pot. Summary of the invention

[0047] Embodiment 1:

[0048] See also Figure 1 and Figure 2 In this embodiment, a control method for preventing pressure overshoot of a cooking device is disclosed, which is applied to a cooking device. Preferably, the control method for preventing pressure overshoot of a cooking device comprises the following steps:

[0049] S1: driving the heating module 4 of the cooking device to operate at a first power;

[0050] Specifically, after the cooking device is powered on and started, the heating module 4 of the cooking device is driven to heat the inner pot 2 at a first power. Optionally, the first power is the rated power of the cooking device; optionally, the user can set the magnitude of the first power through the control panel 6; optionally, the cooking device dynamically adjusts the magnitude of the first power according to the weight of the food in the inner pot 2, wherein the weight of the food can be obtained by a pressure sensor based on the pressure change before and after the food is put in.

[0051] S2: Determine whether the pressure in the pot reaches the first preset pressure value, if yes, execute S3, if no, execute S1;

[0052] Specifically, during the cooking process, the pressure in the pot gradually increases. In this embodiment, the pressure in the pot is monitored in real time by a pressure sensor to determine whether the pressure in the pot has reached a first preset pressure value. When the pressure in the pot reaches the first preset pressure value, S3 is executed to dynamically adjust the power of the heating module 4. When the pressure in the pot does not reach the first preset pressure value, S1 is executed to drive the heating module 4 to continue working at the first power.

[0053] S3: driving the heating module 4 of the cooking device to operate at a second power;

[0054] Specifically, when the pressure in the pot reaches a first preset pressure value, the heating module 4 of the cooking device is driven to operate at a second power. In this embodiment, the second power is less than the first power, that is, when the pressure in the pot reaches the first preset pressure value, the heating power of the heating module 4 is reduced to avoid pressure surge caused by excessive pressure increase in the pot.

[0055] Furthermore, the second power can be zero, that is, when the pressure in the pot reaches the first preset pressure value, the heating module 4 stops heating and uses the residual heat to drive the pressure in the pot to continue to increase slowly, significantly reducing the upward surge phenomenon formed by the pressure in the pot and avoiding various abnormalities caused by it.

[0056] S4: Determine whether the pressure in the pot reaches a second preset pressure value. If so, drive the exhaust module 5 of the cooking device to open the exhaust. If not, execute S3.

[0057] Specifically, the heating module 4 heats the inner pot 2 at the second power so that the pressure in the pot slowly increases. At the same time, the current pressure in the pot is monitored in real time by the pressure sensor to determine whether the pressure in the pot reaches the second preset pressure value. If the pressure in the pot reaches the second preset pressure value, the exhaust module 5 of the cooking equipment is driven to open the exhaust to reduce the pressure in the pot to prevent the pressure in the pot from being too high. If not, S3 is executed to continue to drive the heating module 4 to heat the inner pot 2 at the second power.

[0058] In this embodiment, the second preset pressure value is greater than the first preset pressure value, that is, the heating module 4 first heats the inner pot 2 at the first power to drive the pressure in the pot to reach the first preset pressure value, and then reduces the heating power of the heating module 4 to drive the heating module 4 to heat the inner pot 2 at the second power. When the pressure in the pot reaches the second preset pressure value, the exhaust module 5 of the cooking equipment is driven to open the exhaust to reduce the pressure in the pot and prevent the pressure in the pot from being too high, thereby realizing dynamic adjustment of the heating power in combination with the pressure change in the pot to avoid pressure surge caused by too fast pressure increase in the pot, and effectively prevent the occurrence of various abnormal conditions caused by pressure surge.

[0063] Specifically, after the cooking device is powered on and started, the heating module 4 of the cooking device is driven to heat the inner pot 2 at a first power. Optionally, the first power is the rated power of the cooking device; optionally, the user can set the magnitude of the first power through the control panel 6; optionally, the cooking device dynamically adjusts the magnitude of the first power according to the weight of the food in the inner pot 2, wherein the weight of the food can be obtained by a pressure sensor based on the pressure change before and after the food is put in.

[0064] S12: Determine whether the working time of the heating module 4 reaches the first preset time, if yes, execute S2, if not, execute S11.

[0065] Specifically, the heating module 4 is driven to continuously heat the inner pot 2 at a first power, and it is determined whether the working time of the heating module 4 heating at the first power reaches a first preset time. If so, S2 is executed to further determine whether the pressure in the pot reaches a first preset pressure value. If not, the heating module 4 continues to be driven to continuously heat the inner pot 2 at the first power. In this way, the two dimensions of heating time and pressure in the pot are combined to overcome the influence of fluctuations in the pressure in the pot on dynamic adjustment, improve the accuracy and stability of cooking, and can more accurately dynamically adjust the heating power to avoid pressure surges caused by excessively rapid pressure rise in the pot, effectively preventing the occurrence of various abnormal conditions caused by pressure surges.
