Description

Technical Field

[0001] The utility model relates to the technical field of cabinet air conditioners, in particular to a noise reduction device for a cabinet household air conditioner motor. Background Art

[0002] Cabinet air conditioners are a type of split air conditioners, commonly used in homes and small offices. Cabinet air conditioners have the advantages of high power and strong wind force, and the starting price is relatively higher. They are usually suitable for larger rooms. Whether to buy a wall-mounted air conditioner or a cabinet air conditioner needs to be determined based on the user's actual needs.

[0003] When the existing air conditioner is working, the compressor starts, and the low-temperature and low-pressure refrigerant is pumped into the machine, and then compressed into a high-temperature and high-pressure gas, which is discharged from the compression chamber of the compressor. The high-temperature and high-pressure gas enters the condenser and emits heat through the heat exchange of the condenser. At this time, the refrigerant becomes a high-pressure wet liquid, and the refrigerant passes through the expansion valve and becomes a low-temperature and low-pressure evaporant. At this time, most of the energy is consumed and it becomes a gas state. After the cooperation of the evaporator and its internal fan, these low-temperature and low-pressure gases penetrate into the room, exchange heat with the air and become liquid working fluids, and circulate back and forth in the loop to complete the refrigeration process. During the use of the cabinet air conditioner, noise will occur due to various factors, such as incomplete cleaning of the air conditioner, resulting in clogging of the filter, and then noise generated when the wind flows, as well as noise generated when the motor is running. The existence of noise will affect the user's sleep, and fatigue and discomfort will occur after long-term use under noise. In view of this, we propose a noise reduction device for cabinet household air conditioner motors. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The noise reduction device of the cabinet household air conditioner motor drives the filter cartridge to rotate by starting the driving motor. When the filter cartridge rotates, the driving shaft is driven to rotate through the sliding groove. After the driving shaft rotates, the adsorption rod is synchronously driven to rotate by the driving component. After the adsorption rod rotates, it rubs against the chemical fiber fabric on the vertical plate, thereby generating static electricity. At the same time, when the filter cartridge rotates, the filter cartridge is cleaned with the help of a cleaning plate. The dust in the air caused by the cleaning is adsorbed by the adsorption rod with the help of static electricity. After being adsorbed by the adsorption rod, it contacts the scraper and is scraped off by the scraper. Through the above structure, when the filter cartridge is clogged after long-term use and noise is generated, the user can use the cleaning plate to clean the filter cartridge with relatively simple operation, thereby reducing the noise generated by the clogging of the filter cartridge.

[0016] (2) The noise reduction device of the cabinet-type household air conditioner motor concentrates the wind through the air collecting duct to increase the flow rate, and supports the filter cartridge through the support plate. It can also use the sound-absorbing box and the second partition to reduce the noise of the air conditioner motor and the drive motor, thereby reducing the noise of the motor operation transmitted to the outside. Through the above structure, not only can the cleaning be automatically completed when the filter cartridge rotates, but the noise generated by the internal motor operation and the filter cartridge rotation can also be absorbed by the sound-absorbing sponge, thereby improving the user experience.
