Description
Technical field
The present invention relates to air-conditioning equipment, particularly relate to a kind of air-conditioner that the air outlet of cabinet type indoor machine in the air-conditioner can be opened and closed automatically.
Background technology
Existing cabinet air conditioner, be provided with cabinet, front door, be provided with air outlet, be provided with air inlet in the bottom and the bottom of the two sides of cabinet on the top of front door, front door constitutes the previous section of cabinet, and the slidable panels that opens and closes air outlet is housed on the top of described front door.
The inboard of cabinet is equiped with heat exchanger and drainage arrangement, heat exchanger is that air-supply arrangement and the air-supply arrangement inhaled air that will the room air forced flow be used carry out heat exchange, to keep comfortable pleasant air, the condensed water that drainage arrangement generates this heat exchanger flocks together, to outside drain, thereby finish refrigeration, heating and the dehumidifying work of air-conditioner.
Duty to air-conditioner commonly used is described below below: at first, connect power supply, the compressor that is installed on the off-premises station is started immediately, refrigerant is compressed.Refrigerant after the compression converts low temperature, low-pressure state to through condenser, expansion valve, supply is installed in indoor evaporimeter, the room air that sucks by air-supply arrangement carries out heat exchange, circulate then, the room air that air-supply arrangement sucks is through evaporimeter, convert pleasant air to,, enter indoor again by exhaust outlet.At this moment, the air-conditioner operation conditions of display box inner control outputs to display window by printed wiring board, and operating personnel can observe the operation conditions of air-conditioner by display window, and the operation and control action button can change the operation conditions of air-conditioner.
Prior art discloses a kind of cabinet type indoor machine air outlet opening and closing device of air-conditioner at present, include shutter door, and connecting rod with spring and the tooth bar of controlling this shutter door switch, in the shutter door opening and closing, utilize the position of the elastic force maintenance shutter door of spring, simultaneously in order to guarantee that shutter door also is provided with guider in the shift position exactly specially.Though this air-conditioner can guarantee the smooth and easy of exhaust outlet when air-conditioning is opened, when closing, air-conditioner closes exhaust outlet, do not allow foreign matters such as dust fall into exhaust outlet, air cleaning in the energy holding chamber, but lost efficacy easily in the back because spring repeatedly uses, aging phenomenon, thereby can not effectively guarantee the switching of shutter door.Need take air-conditioner apart and change spring, increase maintenance cost, also need to use connecting rod simultaneously, increase manufacturing procedure, increase cost indirectly as Connection Element; And special guider has also increased processing cost, is unfavorable for market competition.
After also having technology to adopt stepper motor driven gear group to drive to worm screw, drive then by gear drive, worm screw and tooth bar transmission successively again and be used for hiding slide plate and move.This type of technology causes bigger transmission loss easily because drive disk assembly is many, and the uneven phenomenon of transmission.Having is that described slide plate is installed on the main body of cabinet type indoor machine in the prior art mostly again, and this structure will be unfavorable for the maintenance of equipment.
