Temperature sensor structure of microwave oven

Abstract

The invention discloses a temperature sensor structure of a microwave oven, comprising a sensor probe, a sensor housing and a probe hole, wherein the sensor probe is arranged outside an oven cavity of the microwave oven, and is used for receiving infrared signals emitted by foods in the oven cavity through observing holes formed on the oven cavity, measuring the temperature of the foods and converting temperature signals into electric signals to be input into a controller of the microwave oven; the sensor housing is installed on the outer side of the oven cavity by a fixing part, and formed by combining a shell upper cover with a shell lower cover for holding and protecting the sensor probe; and the probe hole is a through hole formed on the shell lower cover such that the sensor probe can receive heat signals, and the shell upper cover and the shell lower cover are fixedly connected by a buckle. Therefore, according to the invention, the production and installation flows can be simplified, and further the cost is saved and the productivity is improved.

Description

technical field [0001] The invention belongs to the technical field of microwave ovens, and in particular relates to a structure of a temperature sensor of a microwave oven which can precisely fix a sensor by means of buckles, bayonet pins, etc., and can save production costs. 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 plate that irradiates microwaves. Commercial microwave ovens are mainly suitable for convenience stores with high usage rates and food stores that ...

AI Technical Summary

Problems solved by technology

[0009] In the prior art, the mutual fixing between the sensor probe and the sensor housing and between the upper cover and the lower cover of the sensor housing need to be realized by using additional accessories such as screws, thus increasing the overall production cost of the microwave oven, and the sensor probe The positioning accuracy cannot be accurately guaranteed when it is fixed, so it will cause the sensor probe to deviate when collecting data, thus affecting the accurate and normal operation of the microwave oven

In the prior art, the sensor shell is generally fixed to the flange outside the oven cavity of the microwave oven by two screws. The fixing is relatively troublesome, and the production efficiency is too low to easily cause waste of manpower and material resources.
