Embodiment Construction

[0034]Hereinafter, a turbofan for blowing and a refrigerator according to the present invention will be explained in more detail.

[0035]As shown in FIGS. 3 to 5, the turbofan for blowing comprises: a base plate 110 of a disc shape having a hub 111 protruding from a center thereof; a plurality of blades 120 disposed on an outer circumerential surface of the base plate 110 with a constant interval therebetween in a circumferential direction, for blowing cool air introduced from the hub 111 in a radial direction; and a shroud 130 connected to the blades 120 in opposition to the base plate.

[0036]A circle that is obtained by connecting outer ends of the respective blades 120 in a radial direction corresponds to an outer circumference of the shroud 130, and is more protruding than an outer circumference of the base plate 110. That is, a diameter (Do) of a circle that is obtained by connecting outer ends of the respective blades 120 is equal to an outer diameter of the shroud 130, but is la...

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 circumerential 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, 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 turbofan for blowing and a refrigerator having the same, and more particularly, to a turbofan for blowing capable of improving a blowing efficiency for cool air and minimizing power consumption and noise, and a refrigerator having the same.BACKGROUND ART[0002]In general, a refrigerator serves to store foodstuffs as a freezing state or a refrigerating state by circulating cool air generated by a refrigerating cycle.[0003]As shown in FIG. 1, the conventional refrigerator comprises a body 10 having a freezing chamber 1 and a refrigerating chamber 2, and a door 3 disposed at a front surface of the body 10 for opening and closing the freezing chamber 1 and the refrigerating chamber 2.[0004]As shown in FIG. 2, a turbofan 9 for forcibly blowing air cooled through an evaporator 7 into the freezing chamber 1 is installed at a rear side of the body 10. A shroud 8 for introducing air blown by the turbofan 9 into the freezing chamber 1 is ...
