Problems solved by technology

[0014] But, in the sleeve hole of the outdoor fan blade sleeve of the above-mentioned prior art window type air conditioner where the motor shaft is installed, there is a column hole section of the boss, that is, the matching part of the blade sleeve and the motor shaft, in the cylindrical shape. Middle back of the bushing, not visible from the front opening of the cylindrical bushing inserted into the motor shaft
Therefore, when assembling the fan in the production line, it is impossible to clearly see the matching part between the sleeve and the motor shaft inside the sleeve hole, resulting in poor workability of the production line and often causing the fan motor to break

Embodiment Construction

[0034] The specific embodiments of the present invention will now be described in detail with reference to the drawings.

[0035] Figure 4 The section of the fan blade sleeve of the outdoor fan of the window air conditioner according to the present invention is shown. As shown in the figure, in the center of the fan blade sleeve 17, there is a sleeve hole 18 for inserting and fixing the fan motor shaft 14. The upper edge of the sleeve hole 18 is provided with an elongated boss 20 protruding downward from the upper wall of the fan blade sleeve 17 , The lower end of the extension boss 20 is a horizontal plane. The extension boss 20 penetrates the entire sleeve hole 18, from the front opening of the sleeve hole 18 inserted into the motor shaft to the inner end of the sleeve hole, and its length is equal to the depth of the sleeve hole 18.

Abstract

A shaft assembling unit of outdoor fan motor on window air conditioner consists of blade sleeve at middle of fan, annular hole for fixing fan shaft, extended boss at top edge of annular hole and platform of motor shaft front. It is featured as forming said boss downwards from blade sleeve stop wall and forming its bottom end to be plane, passing said boss through annular hole and making said boss length be equal to length of platform at front top of motor shaft.

Description

Technical field [0001] The present invention relates to an air conditioner, and particularly relates to an outdoor fan motor shaft assembly structure of a window air conditioner. Background technique [0002] The air conditioner is an artificial indoor climate adjustment device, the main components are refrigeration cycle system and air circulation system. The refrigeration cycle system includes an evaporator and a condenser that constitute a heat exchanger, a compressor, a throttling device, etc., through the change of the state of the refrigerant in the heat exchanger to realize a cycle of heat absorption and cooling and heat release. The air circulation system includes fans, motors, air inlets and outlets, air ducts, etc. The motor drives the rotation of the lower electric fan to force air convection. The refrigeration cycle system and the air circulation system of the air conditioner operate at the same time, so that the air that is sucked into the air conditioner and changes...
