Problems solved by technology

[0004] In order to overcome the deficiencies in the prior art, the present invention provides a motor waterproof mechanism of a drum washing machine, which can solve the problem that the existing motor waterproof mechanism is often sealed with an oil seal or a dynamic and static ring structure. As long as the above-mentioned sealed waterproof motor connection parts are worn, the oil seal will be damaged. Leakage, the sealing effect will be lost, and the dynamic and static rings will be worn, which will also weaken the sealing performance. Once the sealing effect does not meet the requirements, water will enter, thereby corroding the motor and affecting the service life of the washing machine. Technical problem

Embodiment 1

[0025] Please refer to figure 1 and figure 2 As shown, the present invention provides a motor waterproof mechanism for a drum washing machine, including a motor 7, a base 3 and a drum 1, the motor 7 is installed on the top of the base 3, the top of the motor 7 is connected to a rotating shaft 71 in rotation, and the drum 1 Located at the top of the motor 7, the bottom end of the motor 7 is rotatably connected to a transmission rod, the transmission rod is fixedly connected to the rotating shaft 71 through bolts and nuts, the outer surface of the transmission rod is fixedly provided with a protective cover 4, and the protective cover 4 For the waterproofing of the motor 7, the protective cover 4 is set on the outside of the motor 7, the top of the base 3 is embedded with an isolation cover 5, the section of the isolation cover 5 is U-shaped, and the bottom end of the protective cover 4 is embedded in the In the isolation cover 5, the isolation cover 5 is used to prevent dust ...

Embodiment 2

[0028] Please refer to figure 1 As shown, the present invention provides a motor waterproof mechanism of a drum washing machine. This embodiment adopts the same technical solution as that of the first embodiment. The desiccant 6 is located at the bottom of the motor 7, and the silica gel desiccant 6 is used to absorb the moisture in the protective cover 4 to further improve the waterproof performance of the waterproof mechanism.

[0029] When in use, by installing silica gel desiccant 6 in the protective cover 4, the moisture entering the protective cover 4 is adsorbed by the silica gel desiccant 6, reducing the corrosion of the motor 7 by the moisture, and at the same time, the motor 7 is running. Heat is generated, and the rotating blade 41 continuously blows the heat generated by the motor 7 to the silica gel desiccant 6. The silica gel desiccant 6 removes the moisture in it by thermal desorption, and the silica gel desiccant 6 that removes the moisture realizes the adsorpt...

Embodiment 3

[0031] Please refer to figure 1 , image 3 and Figure 4As shown, the present invention provides a motor waterproof mechanism for a drum washing machine. This embodiment adopts the same technical solution as that of the first embodiment. The opening at the bottom of the hole 31 is located inside the dust-proof net 8, the middle of the top of the dust-proof net 8 is fixedly connected with a connecting column 81, the bottom end of the base 3 is provided with an upwardly extending connecting hole 82, and the top of the connecting column 81 extends In the connecting hole 82, the inner wall of the connecting hole 82 is equidistantly fixedly connected with a rubber stop ring 83, and the rubber stop ring 83 is embedded in the outside of the connecting column 81 to complete the fixing of the connecting column 81 in the connecting hole 82. Preferably, the connecting column 81 is a cylinder with an arc surface at the top, which facilitates the connecting column 81 to enter the connect...

Abstract

The present invention discloses a motor waterproof mechanism, which comprises a motor, a base and a roller; the motor is installed at the top end of the base, a rotating shaft is rotatably connected to the top end of the motor, the roller is located at the top end of the motor, and a transmission rod is rotatably connected to the bottom end of the motor and fixedly connected with the rotating shaft through a bolt and a nut; a waterproof protective cover for the motor is fixedly arranged on the outer surface of the transmission rod in a penetrating mode, the motor is sleeved with the protectivecover, an isolation cover is embedded into the top end of the base, the bottom end of the protective cover rotates in the isolation cover, a cleaning hole communicated with the isolation cover is formed in the middle of the bottom end of the isolation cover, and a discharging hole matched with the cleaning hole is formed in the base; blades for heat dissipation of the motor are arranged at the top end of the inner wall of the protective cover at equal intervals, heat dissipation holes extending upwards are formed in the bottom end of the base at equal intervals, and the top openings of the heat dissipation holes are located in the protective cover; the connecting column is additionally arranged in the middle of the top end of the dustproof net, so that a user cleans dust adsorbed on the surface of the dustproof net conveniently.

Description

technical field [0001] The invention relates to a waterproof mechanism, in particular to a motor waterproof mechanism of a drum washing machine. Background technique [0002] The existing DC brushless motors for washing machines are generally directly connected to the transmission mechanism of the washing machine. By adopting this direct connection method, the transmission efficiency of the motor can be improved, and at the same time, the waterproof performance of the motor is required to be higher. [0003] Existing motor waterproof mechanisms are mostly sealed with oil seals or dynamic and static ring structures. As long as the above-mentioned sealed waterproof motor connection parts are worn, the oil seal will leak, and the sealing effect will be lost. The dynamic and static rings will also be worn, and the sealing performance will also be weakened. If the sealing effect does not meet the requirements, moisture will enter, which will corrode the motor and affect the servi...
