Abstract
The utility model discloses a plastic-sealed motor for a washing machine. The plastic-sealed motor for the washing machine comprises a stator assembly (6) wound with a coil, and a rotor assembly (3) inside the stator assembly (6), wherein a plastic sealing layer is arranged on each of the outer surface and the inner surface of the stator assembly (6), so that the whole stator assembly (6) is sealed inside the plastic sealing layers; a first bearing (2) and a second bearing (8) are arranged at the two ends of a rotating shaft (7) of the rotor assembly (3) respectively; the second bearing (8) is installed at the bottom end of the stator assembly (6), while the first bearing (2) is installed inside a front cover (1); the front cover (1) is in interference fit with the interior of the stator assembly (6). According to the utility model, the stator assembly of the motor is in plastic seal, so that the damp environment resistance of the motor can be effectively improved, and electricity leakage and other hazards can be avoided even when water is splashed onto the motor; the stator assembly is provided with the plastic sealing layers, so that the front cover of the plastic-sealed motor can be installed in an interference fit way, and the plastic-sealed motor is more convenient to assemble than the traditional iron-shell motor.
Description
Technical field
The utility model relates to the plastic packaging motor of a kind of motor, particularly a kind of use in washing machine.
Background technology
At present, on market, rotary drum washing machine use washing and dehydration electric motor are all traditional iron-shell motors, after depositing or use after a while, because washing machine internal environment is very moist, even there is part washing machine can have drainage, can cause motor corrosion like this, the line bag of motor also can cause short circuit because of moist environment, even can motor damage.Therefore, traditional iron-shell motor is applied in and in washing machine, not only has certain potential safety hazard, and also can have a greatly reduced quality its useful life.
Utility model content
The purpose of this utility model is, a kind of plastic packaging motor of use in washing machine is provided.It can improve the ability of antagonism wet environment, can improve the reliability of motor stator simultaneously.
The technical solution of the utility model: a kind of plastic packaging motor of use in washing machine, comprise and be wound with the stator module of coil and the rotor assembly in stator module, it is characterized in that: the surfaces externally and internally of described stator module is equipped with plastic packaging layer, the equal plastic packaging of whole stator module is in plastic packaging layer; The rotating shaft two ends of described rotor assembly are respectively equipped with clutch shaft bearing and the second bearing, and the second bearing is installed on stator module bottom, and clutch shaft bearing is installed in protecgulum, and described protecgulum is interference fitted in stator module.
In the plastic packaging motor of above-mentioned use in washing machine, between described the second bearing and stator module, be provided with wave packing ring, can make protecgulum by rotor assembly tensioner in stator module.
In the plastic packaging motor of aforesaid use in washing machine, on the plastic packaging layer surface of described stator module, there are a plurality of grooves that axially (machine shaft direction) arranges.Because the heat conductivility of plastic packaging layer is better than air, so can reduce the temperature rise of motor, improve the efficiency of motor.Groove can utilize the technology groove as dismounting protecgulum simultaneously.
In the plastic packaging motor of aforesaid use in washing machine, described stator module is provided with mounting nuts, and mounting nuts also plastic packaging in plastic packaging layer.
Compared with prior art, the utility model, by the stator module of motor is carried out to plastic packaging, can effectively improve the ability of the moisture resistant environment of motor, even has water to pour on motor and also can not produce the harm such as electric leakage.And owing to there being plastic packaging layer in stator module, so can make protecgulum of the present utility model can adopt the mode of interference fit to install, therefore assembling is more convenient with respect to conventional iron shell motor.
