Refrigerator monitoring device based on refrigerator door opening/closing states and humidity detection

Abstract

The invention relates to a refrigerator monitoring device based on refrigerator door opening/closing states and humidity detection. The refrigerator monitoring device comprises a plurality of contact-type position sensors, a humidity sensor and a master controller, wherein each contact-type position sensor is positioned on the inner side of a corresponding refrigerator door, and is used for detecting the opening/closing state of the corresponding refrigerator door; the humidity detector is used for detecting the humidity in a refrigerator; the master controller is connected with the humidity detector and each contact-type position sensor, and is used for determining whether to start frost detection and automatic defrosting of the refrigerator according to the received humidity in the refrigerator and the opening/closing states of a plurality of refrigerator doors. Through the refrigerator monitoring device, the frost detection and the automatic defrosting of the refrigerator can be performed timely when the refrigerator doors are opened too long or the humidity in the refrigerator is overhigh, and the defrosting efficiency of the refrigerator is improved.

Description

technical field [0001] The invention relates to the field of refrigerator monitoring, in particular to a refrigerator monitoring device based on refrigerator door switch state and humidity detection. Background technique [0002] The application of refrigerators has a long history. With the improvement of people's living standards and the advancement of science and technology, people's demand for refrigerators is not limited to refrigeration. Intelligent and multi-functional refrigerators have become one of the development trends of refrigerators. [0003] During the use of the refrigerator, there is a phenomenon of frost forming on the panel close to the refrigeration equipment inside the refrigerator. There are many reasons for frosting. If the refrigerator door is not closed tightly, it will cause frosting in the refrigerator. Usually cleaned vegetables and fruits are placed in the refrigerator. The water in these foods evaporates and condenses into frost when it is cold...

AI Technical Summary

Problems solved by technology

However, the method of manual defrosting is time-consuming and laborious, and requires a certain amount of maintenance costs. The method of heating and defrosting does not consider the specific use of the refrigerator. Simply heating at regular intervals will cause sometimes the frost layer is too thick and the refrigerator does not arrive at the scheduled time. The situation of being unable to heat up will also lead to blindly heating when the predetermined time is reached when there is no frost, and the defrosting efficiency is low.
