Furnace chamber environment maintenance mechanism

Abstract

The invention relates to a furnace chamber environment maintenance mechanism, comprising: a rotary workbench installed at the bottom of the furnace chamber at a preset height from the furnace bottom and connected to a micro motor whose rotating speed is 2-10 revolutions per minute The time power controller is used to select different powers to cook or defrost the food in the main body of the oven cavity under the operation of the user; the main body of the oven cavity is coated with a metal plate of non-magnetic material, and the Ventilation holes are opened on the top, and the microwaves input into the main body of the oven cavity through the waveguide are reflected back and forth in the oven cavity wall, and every time they propagate, they pass through and pass through the food in the main body of the oven cavity; exhaust air execution equipment, and steam analysis equipment The connection is used to perform an action of discharging the steam in the furnace cavity when the ratio of the sum of the areas of the steam areas to the area of ​​the real-time processing image is greater than or equal to a preset ratio threshold. The invention overcomes the defect that the inner environment of the furnace cavity is easy to condense steam.

Description

technical field [0001] The invention relates to the field of microwave heating, in particular to an oven chamber environment maintenance mechanism. Background technique [0002] The microwave oven adopts microcomputer control technology and sensor sensing technology to realize the intelligent heating and cooking of the microwave oven, which is a major direction of the development of microwave oven technology. This kind of intelligent microwave oven does not require the user to input parameters such as cooking time, heating power, and food weight on the operation buttons. As long as the start button is pressed, the sensors in the microwave oven will continuously output the detected parameters such as food temperature and steam humidity to the Microcomputer control chip, after the microcomputer control chip performs a series of calculations, comparisons and analyzes, it outputs corresponding instructions to automatically control the heating time and power of the microwave oven...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the technical problem that the microwave oven lacks the self-maintenance mechanism of the oven cavity environment in the prior art, the present invention provides an oven cavity environment maintenance mechanism, which analyzes each gradient value of each pixel in the sub-image, and converts each gradient value into The maximum value of is used as the gradient value of the sub-image to provide effective reference data for the data content of the sub-image; more importantly, on the basis of the above-mentioned high-efficiency image processing, an adaptive discharge mode is performed on the steam in the furnace cavity to effectively maintain Environment inside the furnace chamber
