Description
Technical field
The present invention relates to the air-conditioner parts, more specifically to a kind of use electric control system controls link gear, can auto-closing and the device of opening air conditioner wind outlet to reach.
Background technology
The most of air outlet structure that adopts open type of existing cabinet type room air conditioner, air outlet opens wide when air-conditioning is out of service, and dust enters on the fin that sticks to evaporimeter in the air-conditioner easily, has reduced the heat exchange effect of fin, influences machine performance.Interval between the air outlet aerofoil is generally bigger in addition, and foreign matter can enter in the casing of air-conditioner thus, can cause certain infringement to air-conditioner.Some are furnished with the air-conditioner of folding air outlet structure, and its performance is all complete not to the utmost: a kind of is to utilize horizontal aerofoil, and the pendulum angle that strengthens aerofoil is realized the folding of air outlet, and a kind of is to adopt the vertical door of operation up and down.This dual mode is convenient to realize, but the Total tune of outward appearance is not all roses.Another kind of is to utilize many aggregate motions mechanism, realizes the folding of air outlet by the motion that goes out air door, but breaks down easily owing to adopt complicated transmission mechanism, very high to manufacturability and reliability requirement.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of employing simple and effective transmission device, realize the switch of automatic control cabinet formula room air conditioner air outlet.When air-conditioner is out of service, go out air door and close and cover air outlet, prevent that dust and foreign matter from entering in the air-conditioner.Go out air door and close the back and be in same plane with movable front panel, aesthetic in appearance generous, be easy to incorporate in the environment that finishing is provided with.
The present invention adopts the all-in-one-piece air door structure that goes out, and by transmission mechanism, integral body moves downward to opening air outlet fully when controlling out door opening, utilizes air-out student row extruding activity front panel to move backward simultaneously; Whole upwards complete closed air outlet when going out the air door closure, the outside motion of movable front panel is alignd with frame, air outlet.
The present invention includes:
Go out air door, be positioned at the front of air outlet, can move up and down covers or opens air outlet.
Movable front panel, be positioned at air door below, can seesaw is moving up and down of air door to reserve the position.
Frame is positioned at the casing both sides and with to go out air door in the same plane, can blocks out the actuating mechanism of air door and movable front panel.
Actuating mechanism is positioned at the back side of air door and movable front panel, comprises lifting and the pull down mechanism that air door is done upper and lower motion of using that is installed on the driving mechanism mount pad, makes movable front panel do the telescoping mechanism of forward and backward motion and both drive units.
Controller is the electric-control system that is connected with drive unit, can control the action of driving mechanism according to the state of action command and contact switch.
Describedly go out that air door moves downward and the front panel of extruding activity simultaneously moves backward when start, block movable front panel fully and open air outlet until going out air door.This goes out air door and the time moves upward until blocking air outlet fully in shutdown, and movable then front panel is travelled forward until with to go out air door in the same plane by the driving mechanism guiding.
It is described that to use lifting and the pull down mechanism that air door does upper and lower motion can be the tooth bar drive mechanism.
Described telescoping mechanism can be the cam eccentric mechanism, is used for movable front panel and travels forward and reset and the location when retreating.
Described synchronous extruding movable device comprises the guide rail mechanism that is arranged on movable front panel both sides and is arranged on out the guide wheel that matches with guide rail mechanism in the air door both sides that can use air door like this can be in the fixing steady transmission in orientation.Vertically guide wheel extruding activity front panel moves backward, and laterally guide wheel is the sliding guide effect that seesawed of movable front panel.
Slope of guide rail Front-end Design, when going out air door and moving downward, vertically guide wheel is by the height extruding activity front panel motion backward synchronously on slope.
Describedly go out air door and be provided with guiding mechanism, described guiding mechanism comprises and is arranged on out the air door back side, and the guide rail that matches with lifting and pull down mechanism and keep the prerotation vane of the upper and lower easy motion of air door.
The present invention adopts a cover electric-control system, makes in air-conditioning start operation time control that air door descends and the front panel of extruding activity simultaneously moves backward, judge the air door complete opening by the state of contact switch after, carry out the operation of appointment again.Close when shutting down at air-conditioner, electric control system controls go out air door rise to cover air outlet fully after, by the cam eccentric mechanism movable front panel is reset to go out air door in the same plane again.
Good effect of the present invention:
1. close out air door when air-conditioner is out of service automatically, can prevent effectively that dust and foreign matter from entering in the air-conditioner, keep the inside of air-conditioner clean and tidy, evaporimeter has been avoided gathering of dust simultaneously, can keep the air-conditioner stability.
2. air conditioner wind outlet automated manner closure can realize keeping a kind of level and smooth transition with panel, and Decoration Design is merged in moulding, and the air-conditioner surface is complete, and cleaning surfaces is more convenient.
3. use the combination transmission mechanism of cam, rack-and-pinion, make that overall structure is simple, good manufacturability, characteristics that operability is stable.
