Control system and method for intelligent noise reduction refrigerator

Abstract

The invention discloses a control system and method for an intelligent noise reduction refrigerator. The method comprises the steps that whether a person is in a room or not is detected; when it is detected that no person is in the room, the refrigerator operates in a normal mode; when a person is detected indoors, the indoor environment noise intensity is collected, and the sound intensity is alpha; when the environment noise intensity alpha is larger than the maximum noise intensity beta of operation of the compressor of the refrigerator, the refrigerator operates in a normal mode; and when the environment noise intensity alpha is smaller than or equal to the maximum noise intensity beta of operation of the refrigerator compressor, the refrigerator operates in a mute mode. The sound intensity in the environment can be detected, and the starting time and the rotating speed of the compressor are dynamically adjusted on the basis of meeting refrigeration and preservation by combining with the temperature sensor in the refrigerator body, so that a user cannot perceive the running noise of the refrigerator.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a control system and method for an intelligent noise reduction refrigerator. 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. Inside the box are a compressor, a cabinet or a box for the ice maker to freeze, and a storage box with a refrigerating device. The volume of household refrigerators is usually 20 to 500 liters. When the user uses the refrigerator, it is necessary to regularly clean and maintain the refrigerator and perform breathing disinfection, so that it is not only hygienic and clean, but also prolongs the service life of the refrigerator. [0003] In 1910, the world's first domestic refrigerator with compression refrigeration was introduced in the United States. In 1925, the Swedish Lido ...

AI Technical Summary

Problems solved by technology

However, in the actual use process, some shortcomings of the refrigerator are also exposed. For example, when the refrigerator compressor restarts or when the speed is relatively high, it will make a buzzing noise. When the environmental noise is relatively loud, the user may not feel it, but in When taking a lunch break or sleeping late at night, if the refrigerator makes this noise, the user is very disgusted

[0005] When the existing refrigerator is used, it will only start the compressor or adjust the compressor speed according to the actual temperature sensor in the box. This control logic is fixed and prone to noise
