Problems solved by technology

In areas with high altitude and low pressure, the boiling point of the liquid will decrease. If it is still treated according to the boiling point temperature under standard atmospheric pressure, it will cause some problems, such as continuing to heat the water after boiling, resulting in dry burning, or even a fire. May overflow pot etc.

Embodiment Construction

[0024] The concrete realization method of the present invention includes but not limited to following two kinds:

[0025] Method 1: switch, such as figure 1 , 2 Shown:

[0026] Switches are combined with peripheral circuits to form variable level states. Before the cooker is delivered to use, the level state of the switch is set according to the air pressure condition in the user's area (set by changing the switch combination form of the switch). When the cooker is working normally, the main control chip (MCU) recognizes the level state of the switch, and converts the corresponding liquid boiling judgment temperature. After the user selects the cooking mode, it can be heated. When the temperature in the container has reached the boiling point judgment temperature, it will enter the subsequent processing.

[0027] Method 2: EEPROM, such as Figure 3-1 , 3-2 and 4 as shown:

[0028] The EEPROM can be built into the main control chip (MCU) or external to the main control c...

Abstract

The invention relates to a pressure adaptation method for an electric heating cooker and a device thereof. In the method, a boiling point control parameter is set in advance; a main control chip reads the conversion of the boiling point control parameter and carries out cooking according to the converted corresponding liquid boiling temperature; the device comprises a hardware switch which is connected with the main control chip and is used for setting the corresponding boiling point control parameter or a memory which is connected with or arranged in the main control chip and is used for storing the boiling point control parameter. The method and the device thereof set the boiling point control parameter of the electric heating cooker according to different atmospheric pressures (altitude). The main control chip recognizes the parameter and carries out the corresponding heating adjustment. Therefore, the cooker can work normally under various atmospheric pressures (altitude).

Description

technical field [0001] The invention relates to household appliances, in particular to a method and device for adapting the air pressure of an electric heating cooker. Background technique [0002] China has a vast territory, and the altitude and atmospheric pressure of different regions vary greatly, and the boiling points of liquids at different pressures are different. Common electric heating cookers all set the boiling point temperature of the liquid to the boiling point temperature under standard atmospheric pressure. When the temperature of the liquid in the heating container is higher than this temperature, it is considered that the liquid is boiling, and then the corresponding treatment is carried out. In areas with high altitude and low pressure, the boiling point of the liquid will decrease. If it is still treated according to the boiling point temperature under standard atmospheric pressure, it will cause some problems, such as continuing to heat the water after b...
