Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to a blower for an air conditioner, particularly to one capable of having cold air that is circulated by an evaporator to be blown directly and powerfully from a cold-air blower out of wind outlets of faceplates so as to achieve a prompt blowing function and an optimum cold-room effect.

[0003] 2. Description of the Prior Art

[0004] Generally speaking, a known conventional blower for an air conditioning system installed to an upper floor construction includes many wind-out faceplates disposed around an indoor machine and provided with wind outlets connected with the indoor machine by windpipes for blowing cold air into the room. Such wind outlets are provided with guide plates each made integral in a fixed form so that the cold air blown out adjacent the wind outlets is stronger than that with a distance away from the wind outlets, thus unable to provide the room with even cold temperature. Therefore, in order to spread cold air evenly in the room, a lot of wind-out faceplates are needed for installation in different locations of the room, which also requires many windpipes of different length to be connected with the wind-out faceplates. However, cold air transported through such windpipes of different length is hard to keep the same cold temperature when it is finally blown out of the wind outlets of the wind-out faceplates installed in different locations, thus still unable to achieve an even cooling effect in the room.

SUMMARY OF THE INVENTION

[0005] The main purpose of the present invention is to offer a blower for an air conditioner permitting cold air that is circulated by an evaporator to be blown directly and promptly from a cold-air blower out of wind outlets of faceplates so as to achieve a prompt cold-air circulation and an optimum cold-room effect.
