Pulley transmission structure of window air conditioner fan

Abstract

The invention relates to a pulley drive structure of a window type air conditioner, comprising two fans respectively arranged at the inside of a room and the outside of the room; an electric motor is arranged at one side of the space of the outside of the room, an electric motor rotating shaft at one side of the electric motor is connected with fans at the outside of the room, and the other end of the electric motor is connected with a fan at the inside of the room by a belt roller arranged on the electric rotating shaft; in the space at the outside of the room, a plurality of shaft blocks are arranged on the other side which is in correspondence with the electric motor, and the shaft blocks are fixed on the bottom surface of a one-piece box; the rotating shafts are arranged on a plurality of shaft blocks, one end of the rotating shaft is connected with the fans at the outside of the room, the other end thereof is connected with fans at the space at the inside of the room by the other belt roller arranged on the rotating shaft, and the two belt rollers are connected by a belt. In the invention, only one electric motor is needed to be installed to drive the four fans at the outside and inside of the room by the belt rollers, thus reducing the number of electric motors, expanding internal space of the air conditioner, improving air output of the fans and giving full play to the performance of the fans.

Description

technical field [0001] The invention relates to a window type air conditioner, in particular to a belt pulley drive structure of a fan of the window type air conditioner which can save energy and increase the exhaust air volume of the outdoor fan. Background technique [0002] An air conditioner is a device that cools and warms the air in an indoor space after exchanging heat with the refrigerant circulating through the compressor, condenser, expansion device, and evaporator with the air passing through the evaporator. The structure of the air conditioner includes an outdoor unit composed of a compressor, a compressor, and an expansion device, and an indoor unit composed of a fan and an evaporator. The outdoor unit and the indoor unit are connected to each other through refrigerant piping. [0003] The types of air conditioners are divided according to the installation position of the indoor unit, such as upright air conditioners for indoor use, wall-mounted air conditioners...

AI Technical Summary

Problems solved by technology

And drive motor 42 and 42 ', compressor 43 and a row of condenser 44 parallel with fans 41 and 41 ', two fans 41 and 41 ' are all arranged in the space of outdoor side 4, the space that takes is bigger, makes indoor The outer 4 space is relatively narrow

When the outdoor air is sucked into the outdoor space through the suction grilles 7 arranged on both sides of the single box 1, and the indoor air is sucked into the indoor space, due to the narrow space, the sucked air is hindered by the motor and other components, thus affecting the fan. Excessive air volume, so that the performance of the fan can not be fully utilized
