Description

Air conditioner room unit

The utility model relates to a kind of air conditioner room unit.

At present, the air conditioner room unit of use, its air outlet is an open type, so dust enters in the machine from air outlet easily, influences the performance of indoor set.

The purpose of this utility model provides a kind ofly can open air outlet the air conditioner room unit of when not using air outlet being closed when using.

In order to achieve the above object, the utility model is achieved in that it comprises housing, is located at evaporimeter and wind wheel in the housing, is provided with air inlet and air outlet on housing; It is characterized in that: it also comprises the door that air outlet can be opened or closed that is located at the air outlet place; Be provided with the guide pillar that plays the role of positioning on the both sides of door, be provided with the guide groove that matches with guide pillar on the both sides of air outlet accordingly; Be provided with plural driven gear at the air outlet place, each driven gear connects by a rotating shaft; In housing, be provided with driving gear and drive the motor of the forward and reverse rotation of driving gear, this driving gear and the engagement of an above-mentioned driven gear, corresponding on door, be provided with identical with driven gear quantity and with the tooth bar of its engagement; Be provided with the more than one guiding saddle that plays guiding and help sliding effect at the air outlet place, on door, be provided with chute identical with the saddle quantity that leads and that match with it accordingly.Going out two driven gears that are provided with of internal orifice place symmetry, on door, be provided with 2 toothed rack accordingly, every toothed rack and the engagement of driven gear separately.Be arranged with two guiding saddles at the air outlet place, every guiding saddle is made of 2 rollers, is provided with 2 one slide rails accordingly on door, and roller can slide on slide rail.

The utility model compared with prior art has following advantage:

When 1, air-conditioner was not worked, air outlet was closed, and prevented that dust from entering indoor set inside, kept the cleaning of inside and high rate of heat exchange;

2, covered all Longitudinal grille and lined grid and their transmission mechanisms of air outlet after door is closed, made exposed surface attractive in appearance, profile is simple, is convenient to user's cleaning;

3, whole transmission mechanism is simple, reliable, and manufacturing and assembly precision are not high, is convenient to produce in enormous quantities.
