Device for controlling cooling air supply of refrigerator

Abstract

In a refrigerator, in order to provide a device for controlling a cooling air supply of a refrigerator which is capable of regularly maintaining a temperature distribution inside a chilling chamber in a short time by intensively discharging cooling air to a part having a relatively high temperature when a temperature of the part inside the chilling chamber rises due to lots of preserved foods, etc., a device for controlling a cooling air supply of a refrigerator includes a cooling air supply path formed at the upper portion of a mullion wall demarcating a chilling chamber and a freezing chamber and supplying cooling air ventilated by a ventilation fan to the chilling chamber, a cooling air guide path diverged from the cooling air supply path and guiding the cooling air to each part of the chilling chamber, a cooling air duct connected to the cooling air guide path and discharging the cooling air to each partition demarcated by shelves of the chilling chamber and a cooling air control means intensively discharging the cooling air to a partition at which a load has occurred of the partitions demarcated by the shelves of the chilling chamber.

Description

[0001] This application is a divisional application of Chinese invention patent application 02102512.6. technical field [0002] The present invention relates to a control device for cooling air supply for a refrigerator, in particular, to a control device for cooling air supply for a refrigerator, which can properly handle the load of a refrigerating chamber, and adjusts the cooling air flow rate discharged to the refrigerating chamber, so as to reduce the load on the part where the load occurs. Perform centralized cooling. Background technique [0003] A refrigerator is generally divided into a freezing compartment for storing frozen food and ice making and a refrigerating compartment for storing refrigerated food, and the refrigerator includes a cooling system for supplying cooling air to the freezing compartment and the refrigerating compartment. [0004] At present, refrigerators can be basically divided into two categories: general type and side-by-side type. The free...

Problems solved by technology

[0013] However, in the prior art refrigerator control cooling air supply device, when the temperature in the refrigerator room rises due to the opening and closing of the door of the refrigerator room or the food being put in and taken out, the cooling air discharged into the refrigerator room through some cooling air discharge holes The amount of air is constant, so the cooling time required to lower the temperature of the refrigerator increases and it is not possible to properly handle the load of the refrigerator

[0014] In addition, when the cooling air passing through the cooling air discharge hole cools the refrigerating chamber, since the cooling air is continuously discharged into the refrigerating chamber after the temperature of the cooling air reaches the optimum value, the efficiency of the refrigerator is low.

[0015] In addition, although the load appears in a certain part of the refrigerating room due to the storage of food, the temperature distribution in the refrigerating room is inconsistent because the cooling air is evenly discharged to the entire refrigerating room.
