Problems solved by technology

However, this detection method takes a long time, and the enterprise needs to occupy a large production site and consume a large amount of electric energy during mass production, resulting in low production efficiency. At the same time, the steam generated during the test makes the working environment of the workers overheated, etc.

Embodiment Construction

[0026] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] Taking the Midea electric pressure cooker (PCJ505) as an example, the first step is pressure tamping: first prepare a special pot cover for detection (the special pot cover is not necessary, for example, you can set a special quick connection on the electric pressure cooker cover head instead), the cover is provided with an air inlet and a quick connector to connect the air tube, and then the special cover is closed on the pot body of the tested electric pressure cooker, and the pressure is supplied to the pressure cooker through an air compressor or a pressure gas storage container. Fill the pressure cooker with compressed air (or non-toxic inert gas) to make the pressure inside the cooker reach 110kPa, and the inflation time is 3-5 seconds. Its main function is to eliminate the assembly problems of internal parts of the product, esp...

Abstract

The invention relates to a pressure detecting method for an electric pressure cooker. The method comprises the following steps of: regulating pressure in advance: regulating the breaking pressure of a pressure travel switch of the detected electric pressure cooker to a preset value P0; aerating for pressurizing: charging a gas medium into the detected electric pressure cooker to raise the pressure in the detected electric pressure cooker; detecting pressure: recording the product pressure value P of the pressure travel switch at a breaking moment, and comparing the product pressure value P with a detection standard pressure value P1; when the product pressure value P is accordant with the detection standard pressure value P1, entering a next step; when the product pressure value P is not accordant with the detection standard pressure value P1, stopping detection for maintaining; and releasing pressure: releasing the internal pressure of the detected electric pressure cooker. The detecting method can be widely applied to electric pressure cooker products, and is a simple, efficient and accurate detecting method for the working pressure of an electric pressure cooker; and due to the adoption of the detecting pressure, the production field can be saved, electric energy is saved, the production efficiency is increased, and the overheated working environment for workers is improved.

Description

technical field [0001] The invention relates to a method for detecting the pressure of an electric pressure cooker, in particular to a method for detecting the pressure inside the electric pressure cooker during the production and online testing of the electric pressure cooker. Background technique [0002] Existing electric pressure cooker products all will carry out working pressure detection before leaving the factory. The usual practice of enterprises is to add water to the pot and turn the water into steam to test the compliance of the working pressure and the tightness of the pot body, so as to ensure that the working pressure and cooking temperature of the product are controlled within the set range. However, this detection method takes a long time. When the company produces in batches, it needs to occupy a large production site and consume a large amount of electric energy, resulting in low production efficiency. At the same time, the steam generated during the test ...
