Embodiment Construction

[0034] Hereinafter, a turbo fan for blowing air and a refrigerator according to the present invention will be described in detail.

[0035] Such as Figure 3 to Figure 5 As shown, the turbofan for blowing air comprises: a disc-shaped base plate 110 having a hub 111 protruding from the center of the base plate 110; a plurality of blades 120 disposed on the periphery of the base plate 110 The plurality of blades 120 are used to blow cold air introduced from the hub 111 in a radial direction on the surface with a constant interval between the blades in the circumferential direction; and a shroud 130 is connected to the blades 120 opposite to the base plate.

[0036] A circle obtained by connecting the radially outer ends of the blades 120 corresponds to the outer circumference of the shroud 130 and protrudes more than the outer circumference of the base plate 110 . That is, the diameter (Do) of a circle obtained by connecting the outer ends of the blades 120 is equal to the oute...

Abstract

A turbofan for blowing comprises: a base plate having a hub protruding from a center thereof; a plurality of blades disposed on an outer circumerenti al surface of the base plate with a constant interval therebetween in a circumferential direction; and a shroud connected to the blades in opposition to the base plate. An outer diameter of a fan, a height of the blade, an inner diameter of the blade, an inner diameter of the shroud, an entrance angle of the blade, an exit angle of the blade, etc. are designed with an optimum condition, there by improving a blowing efficiency for cool air and reducing power consumption and noise.

Description

technical field [0001] The present invention relates to a turbo fan for blowing and a refrigerator with the turbo fan, in particular to a turbo fan for blowing and a refrigerator with the turbo fan which can improve the blowing efficiency of cold air and minimize energy consumption and noise. Fridge with fan. Background technique [0002] Generally, a refrigerator is used to store food in a frozen state or a refrigerated state by circulating cool air generated by a refrigeration cycle. [0003] Such as figure 1 As shown, a traditional refrigerator includes a body 10 and a door 3, the body 10 has a freezer 1 and a refrigerator 2; [0004] Such as figure 2 As shown, a turbo fan 9 is installed on the rear side of the body 10 , and the turbo fan 9 is used to forcibly blow the air cooled by the evaporator 7 into the freezer compartment 1 . A shroud 8 is installed on one side of the turbofan 9 for introducing the air blown by the turbofan 9 into the freezing chamber 1 . [0...
