Refrigerator and defrosting control method and device thereof

Abstract

The invention discloses a refrigerator and a defrosting control method and device thereof. The method comprises the following steps that whether a refrigerator door is opened or not is judged in the refrigerator operation process; if the refrigerator door is opened, the continuous refrigerator door opening time is obtained, and environment parameters when the refrigerator door is opened are obtained; the refrigerator defrosting period is adjusted according to the continuous door opening time and the environment parameters when the refrigerator door is opened; and when the cumulative operation time of a compressor of the refrigerator reaches the adjusted defrosting period, the refrigerator is controlled to execute a defrosting program. Through the method, by dynamically adjusting the defrosting period according to the environment parameters, the problem that cooling capacity is wasted due to the too short defrosting period when a fixed defrosting period is adopted is effectively solved, or the problem that a refrigerator evaporator is blocked and cannot work normally due to the too long defrosting period is effectively solved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a method for controlling defrosting of a refrigerator, a device for controlling defrosting of a refrigerator, and a refrigerator with the device. Background technique [0002] For air-cooled frost-free refrigerators, the refrigerator needs to be defrosted regularly during use to ensure that the cold air in the refrigerator can circulate normally. [0003] In the related art, a fixed defrosting cycle is used for defrosting, but if the defrosting cycle is set unreasonably, cooling capacity is easily wasted or the evaporator is blocked. For example, in order to ensure the reliability of the product, the defrosting cycle is designed according to the maximum value of the air humidity. Although this method shortens the defrosting cycle, it causes a waste of cooling capacity; If the defrosting cycle is designed with a large value, then when there is an action of opening the door,...

AI Technical Summary

Problems solved by technology

For this reason, the first object of the present invention is to propose a defrosting control method for a refrigerator, by dynamically adjusting the defrosting cycle according to the environmental parameters, thereby effectively solving the problem that the defrosting cycle is too short when the fixed defrosting cycle is adopted. The problem of waste of cooling capacity caused by it, or the problem that the evaporator of the refrigerator is blocked and cannot work normally due to the defrosting cycle setting being too long
