Motor with waterproof cover and drainage pump

Abstract

The invention discloses a motor with a waterproof cover. The motor comprises a motor with a coil assembly, an internal water blocking cover and an external water blocking cover, wherein a wiring sheet is exposed out of a rear part of a shell of the coil assembly, the internal water blocking cover covers the rear part of the shell, a wiring window is arranged in the internal water blocking cover and is used for accommodating the wiring sheet, the external water blocking cover is hinged with or detachably covers an external upper part of the internal water blocking cover and can be closed or opened relative to the internal water blocking cover, the internal water blocking cover and the external water blocking cover are provided with top surfaces, the top surfaces are opposite in inclining directions, at least one part of the top surface of the external water blocking cover shads the top surface of the internal water blocking cover, and the top surface of the internal water blocking cover and the top surface of the external water blocking cover respectively incline and extend towards two sides from a shading part to form diversion inclined surfaces which is high in middle parts and low in two edges. The internal water blocking cover and the external water blocking cove are arranged in the motor shell, waterproof protection of a wiring terminal is achieved, the waterproof effect is favorable, so that the maintenance cost of the motor is reduced, and the service lifetime is prolonged.

Description

technical field [0001] The invention relates to the technical field of motors. Background technique [0002] The motors currently used in drainage equipment such as washing machines have exposed terminals. When the external environment is a high-heat, high-humidity and high-salt environment, the situation of damp is serious. Once the equipment is shaken during use, the water droplets accumulated in the external environment will drip onto the terminal, which will cause short circuit of the motor and rust and corrosion of the lugs. [0003] The date of the announcement is December 14, 2016, the announcement number is CN205805934U, and the Chinese utility model patent titled "A Water Pump with an Input Socket" discloses a waterproof cover for a motor terminal, which has a first water-retaining shell and the second water retaining shell, the first water retaining shell and the second water retaining shell are assembled together by buckling, and the first water retaining shell i...

Problems solved by technology

[0005] The water-repelling shells or waterproof covers in the above patents are all assembled in a nested manner, and water and steam can easily penetrate into the joint between the outer cover and the inner cover.

There is also a practice on the market that the outer waterproof cover is hinged to the rear of the inner waterproof cover. Water seeps easily at the hinged position and the junction of the inner and outer waterproof covers. question
