Refrigerator and its control method

Abstract

The present invention provides a refrigerator, comprising a freezing compartment and a non-freezing compartment which are refrigerated independently, a refrigeration and defrosting system working for the non-freezing compartment, and a control device for controlling the refrigeration and defrosting system, wherein The refrigerating and defrosting system includes an evaporator supplied with refrigerant, a fan for delivering the cold air generated by the evaporator to the non-refrigerated compartment, a heater and other elements, and the control device includes a ring temperature sensor for detecting the ambient temperature During the period when the evaporator is stopped from supplying refrigerant, the control device controls the operating state of the fan based on the ambient temperature value measured by the ambient temperature sensor. In this way, excessive condensation on the inner wall of the non-freezing chamber near the freezing chamber and water dripping in the non-freezing chamber can be avoided, thereby avoiding complaints from users.

Description

technical field

[0001] The invention relates to the technical field of refrigerators, in particular to a household refrigerator and a control method thereof. Background technique

[0002] During the use of household refrigerators, frost will inevitably form on the evaporators in the refrigerator and freezer compartments, so it is necessary to periodically start the heater installed on the evaporators to defrost the evaporators. When the refrigerating room is not cooling, the fan generally operates in an intermittent on / off mode. Under lower ambient temperature conditions, the refrigerating time of the refrigerating room is shorter than the non-refrigerating time, and during this non-refrigerating time, with the intermittent on / off operation of the fan, the cooling capacity of the evaporator will be transferred to In the refrigerator room, the temperature of the evaporator rises above zero, and the frost layer on the evaporator will melt and form water vapor. Under the agita...
