Abstract
The utility model relates to the filed of air conditioner filter, and aims to provide an air return filter without power for an air conditioner, wherein the air return filter uses the negative pressure of the air conditioner as power without power consumption so as to keep a filter screen clean. The air return filter without power for an air conditioner comprises a fan impeller, a cycloid cam speed reducer, a swiveling jib and a filter screen; the rear part of the fan impeller is connected with the swiveling jib through the cycloid cam speed reducer; the side part of the swiveling jib is provided with a soft elastic scraping plate; the soft elastic scraping plate can scrap the dust in a dusty airflow attached to the filter screen; a dust collection groove is formed outside the filter screen; and a dust collection box is arranged below the dust collection groove. According to the utility model, the speed is reduced by the fan impeller through the cycloid cam speed reducer, the swiveling jib is driven to rotate at a low speed, the side part of the swiveling jib is provided with the soft elastic scraping plate, and the dust in the dusty airflow attached to the filter screen can be scraped to fall into the dust collection box. Through the operation, the filter screen is kept clean, and the air flow resistance is reduced; moreover, the negative pressure of the air conditioner is used as power without power consumption in the operation so that the installation power is reduced by 2.57-3.37KW compared with the traditional filter type.
Description
Technical field
The utility model relates to the air conditioner filter field, relates in particular to a kind of air-conditioning equipment and uses the unregulated power return air filter.
Background technology
The clean industry of China air-conditioning is started late, and along with The development in society and economy, the HVAC industry has obtained fast development in recent years, and people's life, work and product processes are had higher requirement to the technical merit of HVAC industry, product quality etc.
Research shows that the filter efficiency of air-conditioning return air inlet filter is most important to the influence of air quality and equipment operation.In order to have kept strainer screen clean, reduced the circulation of air resistance, generally adopt filter, traditional filtering mode installed power is big, needs extra power consumption.
The utility model content
For solving the problems of the technologies described above, it is power with the air-conditioning negative pressure that the purpose of the utility model provides a kind of, need not power consumption, has kept the clean air-conditioning equipment of filter screen to use the unregulated power return air filter.
The air-conditioning equipment of the utility model is used the unregulated power return air filter; Comprise blast fan, cycloidal planetary gear speed reducer, pivoted arm and filter screen; The rear of blast fan is connected with pivoted arm through cycloidal planetary gear speed reducer; The pivoted arm sidepiece is provided with soft elastic scraper, and this soft elastic scraper can be hung dust-contained airflow attached to the dust on the filter screen.
Further, the outside of filter screen is provided with dust collecting trough, and the below of dust collecting trough is provided with disposal box.
Compared with prior art; The beneficial effect of the utility model is: the utility model is because blast fan through the cycloidal planetary gear speed reducer reduction of speed, drives the pivoted arm low speed rotation, and the pivoted arm sidepiece is provided with soft elastic scraper; Dust-contained airflow is hung attached to the dust on the filter screen; Send in the dust collecting trough, the dust in the dust collecting trough falls in the disposal box owing to the gravity effect.Through above operation, kept filter screen clean, reduced the circulation of air resistance, and be in operation with the air-conditioning negative pressure to be power, to need not power consumption, reduce installed power 2.57-3.37KW than traditional filtering mode.
Description of drawings
Fig. 1 is the front view of the utility model air-conditioning equipment with the unregulated power return air filter;
Fig. 2 is the side view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As depicted in figs. 1 and 2; A kind of air-conditioning equipment is used the unregulated power return air filter; Comprise blast fan 1, cycloidal planetary gear speed reducer 2, pivoted arm 3 and filter screen 4; The rear of blast fan 1 is connected with pivoted arm 3 through cycloidal planetary gear speed reducer 2, and pivoted arm 3 sidepieces are provided with soft elastic scraper, and this soft elastic scraper can be hung dust-contained airflow attached to the dust on the filter screen 4.
The outside of filter screen 4 is provided with dust collecting trough 5, and the below of dust collecting trough 5 is provided with disposal box 6.
The utility model air-conditioning equipment is following with the operation principle of unregulated power return air filter:
Air-flow blows to blast fan 1, and blast fan 1 rotates, because blast fan 1 rotating speed is higher; Through cycloidal planetary gear speed reducer 2 reductions of speed, improved moment of torsion, drive pivoted arm 3 low speed rotation; Pivoted arm 3 sidepieces are provided with soft elastic scraper, and dust-contained airflow is hung attached to the dust on the filter screen 4, send in the dust collecting trough 5; Dust in the dust collecting trough 5 falls in the disposal box 6 owing to the gravity effect.
Through above operation, kept filter screen clean, reduced the circulation of air resistance, driven the equipment dedusting, and be in operation with the air-conditioning negative pressure to be power, to need not power consumption, reduce installed power 2.57-3.37KW than traditional filtering mode.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
