Description

Technical Field

[0001] The utility model relates to the technical field of motor dust prevention, in particular to a dust prevention device for a screw compression motor of an air conditioner. Background Art

[0002] A motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor is represented by the letter M (the old standard uses D) in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy. When the motor is in use, a protective cover is sometimes required. The motor cover has two functions. The first is to prevent solids from penetrating into the casing and to prevent people from touching dangerous parts in the casing. The second is to control the air duct. Because the fan is self-cooled, if there is a wind cover, the wind cover will blow to the bottom along the gap between the wind cover and the heat sink (circular distribution), thereby taking away the heat from the heat sink. If there is no wind cover, the fan wind is directionless and the heat dissipation effect is extremely poor. The cooling methods of permanent magnet synchronous motors are divided into two categories: external cooling and internal cooling.

[0003] Patent No. CN218678644U discloses a dustproof motor, including an outer shell and a motor body located in the outer shell, the outer shell is provided with an inner shell and a partition fixed to one side of the inner shell, the inner shell is provided with an inner cavity, the partition divides the interior of the outer shell into a cavity located between the outer shell and the inner shell and a dustproof cavity, the motor body is located in the inner cavity, a cooling device is provided in the cavity, the motor body includes a motor output end, and the motor output end is rotatably connected to the partition; the motor body is placed in the inner cavity, the motor output end passes through the partition, and the motor body can be wrapped in the inner shell, the inner shell can be formed in one piece, and the outer end and the inner end of the motor output end are separated by the partition, the inner shell is fixedly connected to the partition, and relative to the motor body, the connection gap is less, and the sealing effect will be correspondingly improved; the partition can reduce the probability of dust directly entering the motor along the motor output end, greatly improving the dustproof effect of the motor.

[0004] The above-mentioned dustproof motor has the following technical problems: the motor and dust cover are fixed, which is not conducive to the later maintenance and repair of the motor; the dust cover is not equipped with a cleaning device, and after long-term use, dust will accumulate in the ventilation groove of the dust cover, affecting the heat dissipation of the motor, and manual removal is time-consuming and laborious.
