Detailed Description
The core of the invention is to provide a control method and related components for preventing the pressure of the electric pressure cooker from overshooting, which can avoid the problem that the normal use of the electric pressure cooker is influenced and even the safety of a user is threatened by opening a pressure release valve of the electric pressure cooker when the electric pressure cooker works in a high-pressure cooking mode but the weight of food cooked by the electric pressure cooker is actually small.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
When the electric pressure cooker in the prior art works in a high-pressure cooking mode, if the weight of food actually used by a user to cook by the electric pressure cooker is small, the food in the electric pressure cooker is continuously heated by Yu Wenhui of an electric heating plate in the electric pressure cooker, so that the pressure inside the electric pressure cooker exceeds the pressure corresponding to the high-pressure cooking mode, a pressure release valve of the electric pressure cooker may be opened, the normal use of the electric pressure cooker is affected, and even the safety of the user is threatened.
Referring to fig. 1, fig. 1 is a schematic flow chart of a control method for preventing pressure overshoot of an electric pressure cooker, the control method including:
s1: determining the food weight of food to be cooked in the electric pressure cooker;
s2: controlling a heating module in the electric pressure cooker to work at a first preset working power, and controlling the heating module to stop heating when the weight of food to be cooked is smaller than a preset food weight threshold value and the pressure in the electric pressure cooker enters a low-pressure cooking pressure range;
s3: judging whether the pressure in the electric pressure cooker reaches a high-pressure cooking pressure range or not after the heating module stops heating for a preset time; if yes, entering S4; if not, entering S5;
s4: continuing to control the heating module to stop heating, and entering S3;
s5: and controlling the electric pressure cooker to enter a high-pressure cooking mode until the electric pressure cooker meets the preset cooking ending condition, and controlling the electric pressure cooker to stop working.
In order to solve the problems in the prior art, the fuzzy judgment is firstly carried out on the food weight of the food to be cooked in the electric pressure cooker, and the regulation and the intervention are needed to be carried out on the working process of the electric pressure cooker when the food weight of the food to be cooked is less. And controlling a heating module in the electric pressure cooker to work at a first preset working power after determining the food weight of the food to be cooked. The method comprises the steps of judging that the working process of the electric pressure cooker needs to be interfered when the weight of food to be cooked is smaller than a preset food weight threshold value, and therefore when the pressure in the electric pressure cooker enters a low-pressure cooking pressure range, firstly controlling a heating module in the electric pressure cooker to stop working, and therefore before the electric pressure cooker enters a high-pressure cooking mode, firstly starting overshoot prevention protection on the electric pressure cooker, and controlling the heating module to stop working for a preset time. After the heating module stops heating for a preset time, whether the pressure in the electric pressure cooker reaches a high-pressure cooking pressure range is judged, if the pressure in the electric pressure cooker is still in the high-pressure cooking pressure range at the moment, the fact that the electric pressure cooker still needs to be protected from overshoot is proved, that is, the electric pressure cooker also needs to wait for the food to be cooked to continue cooling, and the residual temperature brought to the food to be cooked by early-stage heating of the electric pressure cooker is eliminated. When the pressure in the electric pressure cooker is smaller than the high-pressure cooking pressure range, the electric pressure cooker is controlled to enter a high-pressure cooking mode, at the moment, because the temperature of food to be cooked is lower, when the pressure in the electric pressure cooker is increased to the high-pressure cooking pressure range by the heating module, the food to be cooked does not have higher temperature rise due to the influence of the residual temperature of the electric heating plate, the pressure in the electric pressure cooker is further prevented from exceeding the pressure corresponding to the high-pressure cooking mode, the risk that a pressure release valve of the electric pressure cooker can be opened is eliminated, and the normal use of the electric pressure cooker and the safety of a user are ensured.
It should be noted that the present application is not limited to specific values of the low pressure cooking pressure range and the high pressure cooking pressure range, for example, the low pressure cooking pressure range is 35KPa to 55KPa, and the high pressure cooking pressure range is 65KPa to 85KPa. And whether the pressure in the electric pressure cooker enters the low-pressure cooking pressure range and the high-pressure cooking pressure range is determined in the application, and the low-pressure action signal and the high-pressure action signal sent by the pressure detection module in the electric pressure cooker are judged to be received or not. The pressure detection module is used for detecting the internal pressure of the electric pressure cooker, generating a low-pressure action signal when the internal pressure is within a low-pressure cooking pressure range, and generating a high-pressure action signal when the internal pressure is within a high-pressure cooking pressure range. In addition, in practical application, a high-pressure cooking pressure range and a low-pressure cooking pressure range can be distinguished according to a preset pressure division value, the preset pressure division value is usually set between 55KPa and 65KPa when the electric pressure cooker is used for cooking, if the pressure in the electric pressure cooker is smaller than the preset pressure division value, the pressure in the electric pressure cooker is considered to enter the low-pressure cooking range, and if the pressure in the electric pressure cooker is larger than the preset pressure division value, the pressure in the electric pressure cooker is considered to enter the high-pressure cooking range.
In addition, the preset food weight threshold, the preset duration and the preset cooking ending condition are not particularly limited and can be selected according to actual conditions.
In summary, the invention provides a control method for preventing pressure overshoot of an electric pressure cooker, which comprises the steps of firstly determining the weight of food to be cooked in the electric pressure cooker, controlling a heating module to start heating the electric pressure cooker at a first preset working power, then controlling the heating module to stop heating for a preset time after the weight of the food is smaller than a preset food weight threshold value and the pressure in the electric pressure cooker reaches a low-pressure cooking pressure range, so as to avoid overshoot caused by continuous rising of the pressure in the electric pressure cooker, if the pressure in the electric pressure cooker is in the high-pressure cooking pressure range, proving that the electric pressure cooker needs to be protected by overshoot, and then continuously controlling the heating module to stop heating, and controlling the electric pressure cooker to enter the high-pressure cooking mode to start normal cooking steps until the pressure in the electric pressure cooker does not reach the high-pressure cooking pressure range.

In this embodiment, the preset cooking ending condition that needs to be met when the electric pressure cooker stops working is that the temperature of the bottom of the electric pressure cooker reaches the cooking temperature of the electric pressure cooker and the total heating duration of the electric pressure cooker reaches the cooking setting duration, wherein the cooking temperature and the cooking setting duration are respectively the temperature and the duration corresponding to the cooking mode of the electric pressure cooker set by the user. Specifically, whether the temperature of the bottom of a pot reaches a cooking temperature or not is determined, when the temperature of the bottom of the pot reaches the cooking temperature, a heating module in the electric pressure cooker is controlled to stop heating, whether the total heating time of the electric pressure cooker reaches the cooking time or not is further determined, when the total heating time also reaches the cooking time, the electric pressure cooker is judged to meet a preset cooking end condition, and the electric pressure cooker is controlled to stop working; and when the total heating duration does not reach the cooking set duration, the final working power of the heating module is adjusted based on the current pot bottom temperature of the electric pressure cooker, wherein the current pot bottom temperature is in negative correlation with the final working power, namely the working power of the electric pressure cooker needs to be controlled to be improved when the current pot bottom temperature is lower, and then the heating module is controlled to work according to the final working power and continuously judges whether the electric pressure cooker meets the preset cooking ending condition or not.
In conclusion, when the temperature of the bottom of the electric pressure cooker reaches the cooking temperature of the electric pressure cooker and the heating time of the electric pressure cooker reaches the cooking time, the electric pressure cooker is considered to meet the preset cooking ending condition, and the use reliability of the electric pressure cooker is further ensured.

In conclusion, the embodiment further improves the use experience of the user by controlling the prompt module to generate the prompt information of the cooking technology after the electric pressure cooker finishes cooking.
