Technical Field
[0001] The utility model relates to the technical field of air conditioner outdoor motors, and more specifically, to an end cover with a high-efficiency double anti-shell water seepage structure. Background Art
[0002] The front and rear end covers of conventional air-conditioner outdoor unit motors on the market are fixed by screws and nuts or built-in rivets. The force on the fixed parts is uneven compared to the force on other unfixed parts. Therefore, after the end covers are fixed, there will be a certain gap between the end covers. Water will first penetrate into the sealing ring through the gap of the end cover. After the sealing ring fails due to long-term alternating hot and cold conditions, water will penetrate into the interior of the motor through the sealing ring, thereby destroying the insulation system inside the motor.
[0003] The common treatment solutions on the market are to prevent water seepage by adding sealing rings, but the motor with sealing ring anti-water seepage structure has the following disadvantages:
[0004] 1. The sealing ring is prone to aging and failure due to long-term alternating hot and cold working;
[0005] 2. The design cost is high, and a sealing ring needs to be added between the upper and lower shells;
[0006] 3. The production efficiency is slow, and the sealing ring needs to be put on the iron core during production;
[0007] 4. The comprehensive management cost is high and there is one more material.
[0008] In view of this, research and improvement are conducted on the existing problems, and an end cover with a high-efficiency double anti-shell water seepage structure is provided, aiming to achieve the purpose of solving the problem and improving the practical value through this technology.
