Detecting and warning system for ice accumulation on inner side of back of refrigerator body

Abstract

The invention relates to a detecting and warning system for ice accumulation on the inner side of the back of a refrigerator body. The detecting and warning system comprises a laser distance meter, an infrared transmitter, an infrared receiver and a single-chip microcomputer. The laser distance meter is located at the bottom end of the inner side of a refrigerator door and used for detecting the detection distance between the bottom end of the inner side of the refrigerator door and the bottom end of the inner side of the back of the refrigerator body. The infrared transmitter and the infrared receiver are located at a preset position of the bottom end of the inner side of the left of the refrigerator body and a preset position of the bottom end of the inner side of the right of the refrigerator body respectively and used for detecting the thickness of accumulated ice at the bottom end of the back of the refrigerator body. The single-chip microcomputer is used for carrying out detecting and warning on ice accumulation on the inner side of the back of a refrigerator according to the detection distance and the thickness of the accumulated ice. By means of the detecting and warning system, ice accumulation, caused by excessive water accumulation or limber hole blockage, in the refrigerator can be quickly and accurately known, warning and deicing can be carried out in time when normal work of the refrigerator is affected by the over-thick accumulated ice, and therefore use convenience is brought to users.

Description

technical field [0001] The invention relates to the field of refrigerator detection, in particular to a detection and alarm system for ice accumulation inside the rear of a refrigerator box. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. A compressor, an ice maker, a cabinet or box for freezing, and a storage box with a refrigeration device are arranged in the casing. The volume of household refrigerators is usually 20-500 liters. In 1910, the world's first compression refrigeration household refrigerator came out in the United States. In 1925, the Swedish Lido Company developed a household absorption refrigerator. In 1927, General Electric Company of the United States developed a fully enclosed refrigerator. In 1930, the air-cooled continuous diffusion absorption refrigerator with different heat...

Problems solved by technology

[0006] In order to solve the above problems, the present invention provides a detection and alarm system for ice accumulation inside the rear of the refrigerator box. A laser range finder and an infrared transceiver are introduced to detect the ice accumulation inside the rear of the refrigerator box. In the case of the inside of the refrigerator, the scene shooting is carried out, and the heating plate is introduced to de-ice in real time according to the detection results, so that when the water hole inside the refrigerator is blocked, automatic de-icing can be achieved without manual intervention, and at the same time, the accumulated ice can be removed The situation is displayed to the user at any time, which improves the intelligence of the refrigerator equipment
