Temperature sensor structure of microwave oven

Abstract

The invention relates to a temperature sensor structure of a microwave oven, which comprises a sensor probe and a sensor shell; a sensor base with gradient is arranged outside a furnace chamber; the sensor shell is fixed in a slide way of the sensor base; a single-chip microcomputer controls the sensor shell to slide; the measurement direction of the sensor probe is in parallel with the direction of the slide way; and the field of view of the sensor probe is changed with the position movement, until the single-chip microcomputer judges the field of view of the sensor probe has fully covered the food in the furnace chamber according to the temperature of all sampling points. The field of view of the sensor probe can be synchronously changed according to the size of the food heated in the furnace chamber, so that as many sampling points as possible of the sensor probe are dropped on the food; and the more sampling points which are fully covered on the food, the fuller the temperature distributed on all the points of the food, the closer to the actual status of the food heating, so the heating process is precisely controlled.

Description

technical field [0001] The invention belongs to the technical field of microwave ovens, and in particular relates to a method of setting a sensor shell in a slideway so that the sensor probe moves along the slideway, thereby changing the field of view of the sensor probe in the oven cavity and accurately obtaining the heating status of food in the microwave oven The temperature sensor structure of the microwave oven. technical background [0002] A microwave oven is a device in which a magnetron generates microwaves after the power is turned on, and irradiates these microwaves on food and other heated objects to cook food. Such microwave ovens are classified into domestic microwave ovens equipped with small magnetrons and commercial microwave ovens equipped with large or multiple magnetrons. Microwave ovens can also be divided into household microwave ovens that generally use a glass turntable that rotates food, and commercial microwave ovens that mainly use a diffuser plat...

AI Technical Summary

Problems solved by technology

When the volume of the object to be heated on the food tray is small, there will always be most of the sampling points that cannot fall on the object to be heated, but fall directly on the food tray. The measurement results of such sampling points have no practical value and can only be used It is eliminated by the algorithm, but only a small number of sampling points can actually measure the object, so the actual heating of the food cannot be accurately obtained
