Problems solved by technology

[0006] The problem with this type of electric pressure cooker is that the pressure cannot be adjusted, it is a fixed pressure
The direct result is that there are errors in the detection, and the accuracy and sensitivity are greatly reduced.
In turn, affect the effective control of pressure
Once the detection and control of pressure loses accuracy, it will increase the risk factor of using electric pressure cooker, which is unsafe for users

Embodiment Construction

[0049] Such as Figure 1-5 A temperature-controlled electric pressure cooker with safe pressure relief shown includes a pot cover 1, a pot liner 9, a shell 2, an electric heating device and an electric control device; the shell 2 includes a barrel-shaped metal outer pot 8 and an outer shell, and the pot The lid 1 and the outer pot 8 are connected by a detachable buckle. The lid 1 is processed with lid teeth, and the outer pot 8 is processed with pot teeth. When the lid 1 is rotated, the lid teeth and the pot teeth can be separated or fastened. When cooking, the pot cover 1 and the outer pot 8 are fastened together. When the cooking is finished, when the pot cover 1 is opened, the separation of the pot teeth and the cover teeth can be realized only by rotating the pot cover 1. Body electric pressure cooker. The pot liner 9 is freely placed in the cavity formed between the pot cover 1 and the outer pot 8, and a sealing ring 10 is provided between the pot liner 9 and the pot cov...

Abstract

The invention relates to a safety relief temperature controlled electric pressure cooker and a precious voltage controlling method thereof. The temperature controlled electrical pressure cooler comprises a cooker cover, an inner cooker, an outer cooker, an electric heating device and an electric control gear, wherein the cooker cover and the outer cooker can be connected in a detachably fastened mode; the inner cooker can be freely arranged in a cavity formed between the cooker cover and the outer cooker, and a sealing ring is arranged between the inner cooker and the cooker cover; and the cooker cover is provided with an upper temperature detector for detecting the temperature in the inner cooker, an elastic relief device is arranged between the bottom part of the inner cooker and the outer cooker, and the elastic relief device can sense the cooking pressure in the inner cooker so as to drive the inner cooker to move downwards and comprises an elastic member and a strut member for accommodating the elastic member. The precious temperature controlling method comprises a heating stage in which a master controller heats with small power so as to perform temperature compensation based on the temperature deviation deltaT and the reference temperature deltaTB. The invention can improve the temperature control property and voltage control precision of the temperature controlled electric pressure cooker.

Description

technical field [0001] The invention relates to the field of kitchen cooking utensils, in particular to a temperature-controlled electric pressure cooker capable of safe pressure relief and precise pressure control and a control method thereof. Background technique [0002] In recent years, the electric pressure cooker has replaced the existing old-fashioned open flame pressure cooker due to its energy-saving, fast and convenient advantages, and has become one of the daily household appliances in the family kitchen. There are mainly two types of electric pressure cookers on the market in terms of pressure control and pressure regulation. [0003] The first type is a pressure-controlled electric pressure cooker. A flash switch is provided at the bottom of the outer pot of the electric pressure cooker, and the heating plate is provided with a touch rod that can touch the on-off of the flash switch. The electric heating device is triggered or disconnected by using the inner po...
