Refrigerator

Abstract

The present invention provides a refrigerator in which the manufacturing efficiency of a refrigerator is improved, repair or replacement of parts is facilitated even when a cooling failure occurs, or the cooling failure is suppressed to ensure cooling performance or improve reliability. Equipped with a refrigerator compartment (52) at the top of the freezer compartment (53), equipped with a vegetable compartment (54) at the bottom of the freezer compartment (53), and equipped with an electric cooler (58) and blower (64) at the back of the freezer compartment (53). In the refrigerator, a valve device (65) is provided above the blower (64) to control blowing cold air to the refrigerator compartment (53), and a part of the cold air through the valve device (65) is transported to the vegetable compartment (54).

Description

technical field [0001] The present invention relates to a refrigerator with a refrigerating compartment above the freezing compartment and a vegetable compartment below. Background technique [0002] Conventional refrigerators having a refrigerator compartment above the freezer compartment and a vegetable compartment below are disclosed in Patent Document 1-JP-A-4-103984 and Patent Document 2-JP-A-8-94231. In Patent Document 1, cool air is sent from a cooler arranged at the back of the freezer compartment to each compartment through a fan device. In particular, the cold air that cools the refrigerator above the freezer is sent to the vegetable compartment below the freezer, and the cold air that cools the vegetable is returned to the cooler, thereby simplifying the air passage for the circulation of cold air. [0003] Moreover, in Patent Document 2, the cold air sent from the cooler room at the back of the freezer by the fan unit is divided into the discharge air duct for t...

Problems solved by technology

In short, as the overall cooler 10a varies in the amount of frosting, the cooling effect of the cooler as a whole may be impaired.

In addition, the return cold air from the refrigerator compartment 7 returns to the cooler compartment 10 through the second duct 20 arranged on the back side of the freezer compartment 8 as a path from the upper side to the lower side, so even if the surrounding of the second duct 20 is insulated The material is covered, and the high-temperature and high-humidity return cold air is easily cooled again by the low temperature of the freezer chamber 8, and frosting is easy to occur on the second pipe 10

[0027] If frost occurs, cooling failure will easily occur in any of the storage compartments of the refrigerator compartment 7, the freezer compartment 8, and the vegetable compartment 9, so that the cooling performance may be lowered and the reliability may be lowered.
