Refrigerator draining control method, draining mechanism and refrigerator

Abstract

The invention provides a refrigerator draining control method, a draining mechanism and a refrigerator. The draining control method comprises the following steps of obtaining a defrosting signal of the refrigerator, and when the defrosting signal is produced by the refrigerator, enabling a draining channel of the refrigerator to be closed to enable products in the defrosting process of the refrigerator to be accumulated in the draining channel; obtaining an opening signal of the draining channel, when the opening signal is produced by the refrigerator, communicating the draining channel to enable the products in the defrosting process of the refrigerator to be transmitted out from the draining channel, and after the draining channel is closed, enabling a mixture of glazed frost and condensation water generated during defrosting to be accumulated in the draining channel, wherein the density of the glazed frost is low, so that the glazed frost floats on the condensation water, the vertical height of the glazed frost rises along with the increasing of the condensation water, and the glazed frost is under a motion state and cannot block up the draining channel; and when the mixture ofthe glazed frost and the condensation water needs to be drained, opening the draining channel to enable the mixture of the glazed frost and the condensation water to be synchronously drained, so thatblocking up of the draining channel of the refrigerator is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a refrigerator drainage control method, a drainage mechanism and a refrigerator. Background technique [0002] The drain channel of the refrigerator is used to drain the condensed water in the refrigerator, specifically, it can be discharged to the outside of the refrigerator or to the evaporating dish of the refrigerator. When the evaporator of the refrigerator defrosts, blocky residual frost will fall from the evaporator. When the residual frost flows along the surface wall of the drainage channel, it is easy to accumulate and squeeze and block the drainage channel. Contents of the invention [0003] In view of the above problems, an object of the present invention is to provide a refrigerator drainage control method, a drainage mechanism and a refrigerator that overcome the above problems or at least partially solve the above problems. [0004] One aspect of th...

AI Technical Summary

Problems solved by technology

When the evaporator of the refrigerator defrosts, lumpy residual frost will fall on the evaporator. When the residual frost flows along the surface wall of the drainage channel, it is easy to accumulate and squeeze and block the drainage channel.
