Description

Refrigerator and defrosting control method thereof

Technical Field

The utility model belongs to the technical field of refrigerators, and particularly relates to a refrigerator and a defrosting control method of the refrigerator.

Background

A refrigerator is an electric appliance for storing foods and beverages, which maintains an internal temperature below room temperature by means of a refrigerating system to extend the shelf life of the foods. During freezing, frost may accumulate inside the refrigerator, which affects the performance and energy efficiency of the refrigerator, and thus, the refrigerator needs to be thawed periodically to remove the frost, and some early automatic thawing refrigerators use a timer to control a thawing cycle. The timer will periodically shut down the refrigeration system and activate the heating element to melt the frost, however, this method may not be intelligent enough because it may lead to energy waste regardless of the actual degree of frost accumulation, modern refrigerators typically employ temperature-based defrost control methods that are equipped with sensors to monitor the temperature and humidity within the freezer compartment, and when frost accumulates to a certain degree, the refrigeration system is suspended and the heating element is activated to melt the frost, and once the frost has been melted, the refrigeration system resumes operation. This method is more intelligent and energy efficient because it does defrost according to actual needs rather than on a fixed schedule, another method is pressure-based defrost control, which affects the pressure in the freezer compartment as frost builds up inside the freezer compartment, and by monitoring these pressure changes, the refrigerator can determine when defrost is needed.

The utility model discloses a refrigerator (publication number: CN 216282232U), which relates to the technical field of refrigeration equipment and comprises: a case provided with a refrigerating chamber; a drain pipe communicating with the refrigerating chamber and having a drain port for draining water; the water outlet is arranged at one end of the water outlet pipe far away from the refrigerating chamber, and the water outlet is arranged towards the side of the box body; further comprises: and the sealing cover is arranged at the water outlet in a turnover way and is used for sealing the water outlet. The utility model provides a refrigerator, wherein an opening of a drain pipe faces to the side of a refrigerator body, and a sealing cover capable of swinging is arranged on a drain outlet. Not only can the defrosting water be discharged, but also the force for opening the door body can be reduced, when the refrigerator is used for thawing food, water drops attached to the surface of the food drop into the food storage drawer, so that frost is formed in the food storage drawer, the thawing of frozen food is uneven, the quality of the food is reduced, and the improvement is needed.
