A kind of defrosting method and freezing equipment

Abstract

The invention belongs to the technical field of refrigerating equipment, and discloses a defrosting method and refrigerating equipment. The defrosting method comprises the steps of adjusting the defrosting interval time according to the door opening time of a refrigerating chamber; adjusting the defrosting interval time according to the excessive frosting times; judging whether the temperature ofa cold storage sensor is larger than the preset cold storage limitation temperature or not; if the temperature of the cold storage sensor is not larger than the preset cold storage limitation temperature, resetting an excessive frosting timer; if the temperature of the cold storage sensor is larger than the preset cold storage limitation temperature, judging whether the temperature of a refrigerating sensor is smaller than the preset refrigerating limitation temperature or not; if the temperature of the refrigerating sensor is not smaller than the preset refrigerating limitation temperature, resetting the excessive frosting timer; if the temperature of the refrigerating sensor is smaller than the preset refrigerating limitation temperature, enabling the excessive frosting timer to start timing; judging whether time read by the excessive frosting timer is larger than the preset limitation time or not; if the time read by the excessive frosting timer is larger than the preset limitationtime, resetting the excessive frosting timer, and entering an excessive frosting processing program; judging whether the accumulated running time of a compressor reaches to the adjusted defrosting interval time or not; and if the accumulated running time of the compressor reaches to the adjusted defrosting interval time, resetting the excessive frosting timer, and entering a normal defrosting program. According to the defrosting method and the refrigerating equipment provided by the invention, defrosting is immediately carried out if excessive frosting is determined, the defrosting interval time is shortened, and excessive re-frosting is prevented.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to a defrosting control method for preventing excessive frosting of the refrigeration equipment and the refrigeration equipment. Background technique [0002] The defrosting rules of most domestic refrigerators and other refrigerating equipment are to set a timer to accumulate the working time of the compressor from the end of the pre-cooling time, and enter the defrosting program after the compressor runs for a certain period of time; Frost time, when the frosting time is up, it will enter defrosting. Both of these methods use timing methods, but due to the uncertainty of the user's use and the possible changes in the performance of the frost itself, the established frosting time may not be optimal, and there may be excessive frosting and insufficient defrosting. In extreme cases, it needs to be readjusted to ensure the cooling effect of refrigerators a...
