Motor lead wire water block-proof structure of air conditioner outdoor set

Abstract

The present invention discloses a water stoppage resistance structure for outdoor machine wire lead of air-conditioners, which comprises a stator in an end cap of a motor and a motor shaft connected with a motor rotor through the motor end cap. An upper end of the water stoppage resistance structure formed with a rectangular flange. A cinquefoil hole is formed at center of the water stoppage resistance structure. A gap is formed at center of the flange and on the cinquefoil hole. In addition, a groove is formed along a left side, a right side and a lower end of the water stoppage resistance structure. Width of the groove is slightly larger than thickness of the motor end cap 1. Depth of the groove achieves 5cm to 10cm. The present invention can reduce a clearance between the wire leads, ensure a wall of a round hole on the end cap closely contacts the water stoppage resistance structure, achieve excellent hermetic performance, effectively prevent condensed water and dust entering into the motor and effectively protect the motor wire lead from being scuffed.

Description

technical field [0001] The invention belongs to an outdoor unit of an air conditioner, and in particular relates to a waterproof plugging structure for a lead wire of an outdoor unit of an air conditioner. Background technique [0002] Generally speaking, air conditioners are devices that keep the indoor air environment fresh, and can be roughly divided into split air conditioners and integrated air conditioners. The performance of the split type air conditioner is about the same as that of the integrated air conditioner. [0003] The outdoor unit and the indoor unit of the split-type air conditioner are set separately. The split-type air conditioner includes: the evaporator performs heat exchange to generate cold or warm air, and the indoor unit composed of a blower fan that blows the cold or warm air to the room, and a compressor. An outdoor unit composed of components such as the compressor and condenser of the refrigerant in the pipeline of the air conditioner. And an ...

AI Technical Summary

Problems solved by technology

[0009] But because the bottom flange 6 of the lead wire waterproof plug 4 of the air conditioner outdoor unit motor of the prior art is circular, and is single-layer located inside the motor end cover, this structure cannot effectively protect the lead wire 5, causing the lead wire 5 to be easily damaged. scratch

Moreover, the circular surface cannot be effectively attached to the surface of the motor end cover 1. Condensed water and sand and dust are easy to enter the motor and affect the life of the motor. At the same time, the amount of materials used is large and the product cost is increased.
