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 on the top of front door, be provided with air inlet in bottom and the bottom of the two sides of cabinet, front door consists of 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 the air that the air-supply arrangement that will the room air forced flow be used and air-supply arrangement suck carries 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 the refrigeration of air-conditioner, for warm dehumidifying work.
The below is described below the duty of air-conditioner commonly used: at first, plugged starts the compressor that is installed on the off-premises station immediately, and 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, then circulate, the room air that air-supply arrangement sucks is through evaporimeter, convert pleasant air to, by exhaust outlet, again enter indoor.At this moment, the air-conditioner operation conditions of control outputs to display window by printed wiring board in the display box, and operating personnel can observe by display window the operation conditions of air-conditioner, 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 the 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.Although 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 the foreign matters such as dust fall into exhaust outlet, air cleaning in the energy holding chamber, but because spring repeatedly uses rear easy inefficacy, aging phenomenon, thereby can not effectively guarantee the switching of shutter door.Need to take air-conditioner apart and change spring, increase maintenance cost, also need simultaneously to use connecting rod as Connection Element, increase manufacturing procedure, indirectly increase cost; 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, then drive for hiding slide plate by gear drive, worm screw and rack-driving successively again and move.This type of technology causes larger transmission loss easily because drive disk assembly is many, and the inhomogeneous 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.
