Description
Technical field
The present invention relates to field of air conditioning, particularly relate to a kind of air conditioner filter element and clean device.
Background technology
Air-conditioning is that the temperature to air, humidity, degree of purity, air velocity process, and meets people raw
Product, the equipment of living needs.And containing many different granules in room air, as dust, pollen,
Coal smoke, abrasive grains, ozone, abnormal flavour, nitrogen oxides, sulfur dioxide, carbon dioxide, benzene etc., people
Body suck such air easily produce anaphylaxis, pulmonary injury, irriate and mood is irritated, and
Air-conditioning can be made once these granules enter contaminated inside air-conditioning, cooling system performance reduces.Therefore, empty
Adjust except there is cooling, heating up, in addition to the function that dehumidifies, in addition it is also necessary to there is the function of purification air.
The function of air conditioning purge air is typically realized by the filtration of air conditioner filter element, i.e. at room air
First use air conditioner filter element to carry out filtration, purification when entering air-conditioning, then carry out heating up or cooling process, then will
Heat up or the purification air of cooling enters indoor again.And air-conditioning is in use, air conditioner filter element is very
It is easily stained with many dust, causes the filtering function of air conditioner filter element to go down, accordingly, it would be desirable to timing is to air-conditioning
Filter element is cleaned processing.But existing air conditioner filter element clean method is required to air conditioner filter element from air-conditioning
In take apart, the most again with clear water rinse or with aerator blowing cleaning, not only operate complexity, consumption
Time effort, input cost is higher, and clean air conditioner filter element time air-conditioning cannot normally work, impact use
Family uses air-conditioning.
Summary of the invention
The technical problem to be solved is to provide that one is more cost-effective, operate with simple side
Just, air conditioner filter element automatic clearing apparatus time saving and energy saving, that clean without dismantling air conditioner filter element to realize.
The technical scheme is that

Side, the underface of described air-conditioning condenser 4 bottom, the bottom of described water spilage tray 10 is arranged by condensed water
Put pipe 11 to be connected with the bottom of described water-logging box 8, the aperture area of described water spilage tray 10 more preferably greater than
The aperture area of described water-logging box 8；Water spilage tray 10 coordinates water-logging box 8 using effect more preferable, Ke Yigeng
The outside condensed water formed of good access air-conditioning condenser 4, had both avoided condensed water to drip in air conditioner casing 1
Splashes when falling, preferably protection air-conditioning inner components, the collection condensed water can more concentrated again,
Reduce the loss of condensed water, and common air-conditioning be generally provided with the water spilage tray for access condensed water,
Directly can reequip existing air-conditioning, production and processing is convenient.
In the present invention, described cartridge cleaning device the most also include driving described upper block roller 5 or under lead
The driving means 9 that supporting-point roller 6 rotates, described driving means 9 can be to be positioned at described air conditioner casing 1 outside
Manual rocker, described manual rocker is in transmission connection with described upper block roller 5 or lower tumbler roller 6, it is possible to
Think that the electric driver being positioned at described air conditioner casing 1, the outside of described air conditioner casing 1 are provided with control
The switch that described electric driver is turned on and off, described electric driver is preferably minitype speed reducing motor；
So without opening air conditioner casing 1 or using other instruments, upper block can be made by driving means 9
Roller 5 or lower tumbler roller 6 rotate, thus drive circulation filter element 7 to rotate, and use operation more
Simple and convenient, more laborsaving, and the cleaning of air conditioner filter element can also be completed during operation of air conditioner
Work, better meets the demand of user；And the circulation filter element 7 of endless track shape circulates slow rotation
Can make circulation filter element 7 when through lower tumbler roller 6, be immersed in the time in water-logging box 8 condensed water more
Long, clean more clean thorough.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all in the present invention
Spirit and principle within, any modification, equivalent substitution and improvement etc. made, should be included in this
Within bright protection domain.
