Refrigerator and refrigerator defrosting control method

Abstract

The invention discloses a refrigerator which comprises a refrigerator body, a refrigerator door and a detection system. A plurality of storage chambers are arranged inside the refrigerator body, the refrigerator door is arranged at the openings of the storage chambers, and the detection system comprises an environment temperature sensor, an environment humidity sensor, an evaporator temperature sensor and a refrigerator door opening and closing sensor. A controller is configured to obtain the current environment temperature collected by the environment temperature sensor, the current environment humidity collected by the environment humidity sensor, the evaporator temperature collected by the evaporator temperature sensor and the door opening time collected by the refrigerator door opening and closing sensor, obtain accumulative operation time of the compressor after the last defrosting period is finished, and execute a defrosting program according to a preset defrosting calculation strategy based on the current environment temperature, the current environment humidity, the evaporator temperature, the door opening time and the accumulative operation time. The invention further discloses a refrigerator defrosting control method, and by means of the refrigerator defrosting control method, the defrosting efficiency of the refrigerator can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator and a method for controlling defrosting of the refrigerator. Background technique [0002] For frost-free refrigerators, the most important performance is defrosting. How to ensure the timeliness of defrosting is a problem that must be solved for air-cooled refrigerators. The defrosting cycle is related to the running time of the compressor and the frequency of use of the user. , ambient temperature, and ambient humidity. At present, most frost-free refrigerators only take into account the running time of the compressor and the user's frequency of use, and do not include the ambient temperature and ambient humidity as factors affecting the defrosting cycle. As we all know, the high-humidity gas at the same temperature and the high-temperature gas at the same humidity have relatively more water content. When passing through the evaporator, the water that can ...

Problems solved by technology

At present, most frost-free refrigerators only take into account the running time of the compressor and the user's frequency of use, and do not include the factors affecting the defrosting cycle for the ambient temperature and ambient humidity.

As we all know, the high-humidity gas at the same temperature and the high-temperature gas at the same humidity have relatively more water content. When passing through the evaporator, the water that can be diluted is relatively large, and the frosting speed of the evaporator is fast, so it needs The defrosting control is activated in a relatively short period of time. Therefore, the existing frost-free refrigerators do not add the ambient temperature and ambient humidity to the defrosting cycle factors, resulting in low defrosting efficiency of the refrigerator.
