Embodiment Construction

[0032] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0033] Such as figure 1 As shown, a pressure cooking appliance 1 according to an embodiment of the present invention includes an inner pot 11 , a pressure limiting device 12 , a heating device 13 for heating the inner pot 11 and a control device 10 for the pressure cooking appliance. Wherein, the pressure limiting device 12 can discharge the gas in the inner pot 11 when the pressure value in the inner pot exceeds the set pressure threshold, thereby increasing the air pressure in the pressure cooking appliance 1; the type of the pressure limiting device 12 is here Without limitati...

Abstract

The embodiment of the invention provides a control device and a control method used for a pressure cooking utensil, and the pressure cooking utensil, and belongs to the technical field of pressure cooking utensils. The control device comprises a detecting device and a control device, wherein the detecting device is configured to detect the working parameters of the pressure cooking utensil; the control device is configured to judge that whether the pressure cooking utensil is in the heating dynamic balance state or not according to the working parameters, wherein the heating dynamic balance state is the state under which no unsaturated steam exists in an inner pot; and if the pressure cooking utensil is in the heating dynamic balance state, the heat power of the heating device is controlled to be reduced. Therefore, the reliable pressure control for the pressure cooking utensil is compensated, the condition of overpressure or underpressure caused in the pressure control process is solved, meanwhile, the water loss in the heating process is also avoided, and thus the occurrence of the dry-burning phenomenon is completely eradicated.

Description

technical field [0001] The invention relates to the technical field of pressure cooking appliances, in particular to a control device and method for a pressure cooking appliance and the pressure cooking appliance. Background technique [0002] As a commonly used household appliance, pressure cooking appliances have been accepted and recognized by consumers. At present, the control strategies of pressure cooking appliances for the pressure of the inner pot usually have two directions: one is to control the pressure by using a pressure switch; the other is to use the positive correlation between pressure and temperature to detect the temperature through a temperature sensor and based The temperature detected by the sensor is used to control the pressure applied. [0003] However, the inventor of the present application found in the process of practicing the present application: on the one hand, if a pressure switch is used to control the pressure, the accuracy of the pressure...
