Problems solved by technology

[0003] The current control scheme will cause the pressure switch to move frequently, which will affect the life of the pressure switch, thereby affecting the service life of the electric pressure cooker, and because the pressure value in the electric pressure cooker is related to the displacement of the pressure switch, the range that the pressure value can maintain The value is affected by the accuracy of the pressure switch; and because the pressure switch is prone to failure, there will be hidden dangers of abnormal high pressure or pressure release in the electric pressure cooker

Embodiment 1

[0030] see figure 1 , which shows a control method provided by an embodiment of the present invention, which can be applied to a cooking device provided with a pressure detection device and a temperature sensor, and the method includes:

[0031] S101: Detect the inner cavity pressure value of the inner tank by the pressure detection device during the heating process;

[0032] S102: When the detected pressure value rises to a preset first pressure threshold, detect the current corresponding first temperature value through the temperature sensor;

[0033] S103: When the detected pressure value rises to the preset first pressure threshold and then drops to the preset second pressure threshold, use the temperature sensor to detect the current corresponding second temperature value;

[0034] S104: Set a temperature reference value according to a preset setting strategy and the first temperature value and the second temperature value;

[0035] S105: Comparing the current temperatu...

Embodiment 2

[0061] Based on the same technical concept as the foregoing embodiments, this embodiment will describe the technical solutions of the foregoing embodiments in detail through the following specific examples. When the pressure value detected by the pressure detection device rises to the first pressure threshold, the heating device will be turned off; and after the heating device is turned off, it will be turned on again when the pressure value detected by the pressure detection device drops to the second pressure threshold The heating device, therefore, during the working process of the cooking device, the pressure value detected by the pressure detection device will rise to the first pressure threshold more than once, and will drop to the second pressure threshold more than once.

example 1

[0063] see image 3 , the specific flow of the control method shown in this example may include:

[0064] S301: heating and detecting the inner cavity pressure value of the inner tank;

[0065] S302: Determine whether the detected pressure value is greater than the first pressure threshold P1; if so, go to S303; otherwise, go to S301 to continue heating and detect the inner cavity pressure value of the inner tank;

[0066] S303: Turn off the heating device and detect the inner cavity pressure value of the inner tank;

[0067] Understandably, when the heating device is turned off, the temperature of the inner tank will gradually decrease, and the pressure value will also decrease accordingly.

[0068] S304: Determine whether the detected pressure value is less than or equal to the second pressure threshold P2; if so, go to S305; otherwise, go to S303 to continue detecting the inner cavity pressure value;

[0069] S305: Record the temperature value Ton at this time, turn on t...

Abstract

The embodiment of the invention discloses a control method and equipment. The method can comprise the steps of detecting an inner cavity pressure value of an inner container through a pressure detection device in the heating process; when the detected pressure value is increased to a preset first pressure threshold value, detecting a current corresponding first temperature value through a temperature detector; when the detected pressure value is increased to the preset first pressure threshold value and then is lowered to a second preset threshold value, detecting a current corresponding second temperature value through the temperature sensor; setting a temperature reference value according to a preset setting strategy, the first temperature value and the second temperature value; comparing the current temperature value detected by the temperature sensor with the temperature reference value, and controlling opening and closing of a heating device according to the comparing result. By means of the control method and equipment, the frequency of using the pressure detection device is reduced, and pressure of the inner container of cooking equipment is more precisely and stably controlled.

Description

technical field [0001] The invention relates to the technology of household electrical appliances, in particular to a control method and equipment. Background technique [0002] At present, the electric pressure cooker controls the heating of the electric pressure cooker through a displacement detection pressure switch. The specific control scheme is as follows: the pressure switch is closed, so that the heating tube is energized and heated. During the heating process, the pressure value in the electric pressure cooker will increase, thereby pushing the pressure switch to generate displacement. When the displacement reaches a certain distance, the pressure switch is disconnected. , so that the heating tube stops heating, and the pressure value in the electric pressure cooker will decrease as the temperature drops. When the pressure value decreases to a certain range, the pressure switch will be closed again, so that the heating tube continues to be energized and heated, and ...
