Problems solved by technology

[0014] However, if the height of the shroud 8 is increased to increase the height of the blades 9b, in other words, if the shroud 8 becomes closer to the casing 10, the flow path of the cold air formed by the grille 4 and the shroud 8 will Narrows, thus increasing the loss of cool air flow towards the hub 9a'
Enlarging the casing 10 to prevent this loss leads to the problem of increasing the overall size of the refrigerator

Abstract

The present invention provides a cool air supplying apparatus for a refrigerator including a turbo fan configured to a grill forming a freezing space to blow cool air into the freezing space; and a shroud configured between a casing and the grill so as to cover the turbo fan and includes an opening part which sucks cool air, an orifice formed at an end of the opening part, an inclined part formed so as to incline toward the grill from one end of the orifice, and a flat part formed so as to be integrated with the inclined part and configured at a constant interval from the grill. Therefore, it is possible to increase the height of the blades of the turbo fan without increasing the total size of the refrigerator and causing resistance to the inflow of cool air.

Description

technical field [0001] The present invention relates to a cold air supply device for a refrigerator and a refrigerator with the cold air supply device, in particular to a cold air supply device for a refrigerator and a refrigerator with the cold air supply device. In the cold air supply device, An inclined portion is formed near an opening of the shroud forming a flow passage for inflow of cold air so that the opening protrudes. Background technique [0002] A refrigerator is a home appliance for keeping food stored in a storage compartment thereof fresh by performing a refrigeration cycle. [0003] First, refer to Figure 1 to Figure 3 Explains the structure and operation of the refrigerator, especially the structure and operation of the part for discharging cold air. [0004] here, figure 1 To show a view of a refrigerator according to conventional technology with the door open. figure 2 Fig. 1 shows an evaporator disposed on the rear side of the rear side wall of the...
