Abstract
Description
- The present invention relates to an air conditioner equipped with an open/close mechanism for varying an inlet of air flowing into a heat exchanger arranged in the air conditioner.
- An air conditioner includes a heat exchanger and a fan arranged therein. While the air conditioner operates, a front panel of the air conditioner is made open to widen an air inlet such that a sufficient amount of air can flow into the heat exchanger. An intake grille is divided into upper and lower grilles to which gears are provided respectively. A middle gear engaged with one of the gears is driven by a motor to rotate the one gear, and a rack (linear gear) engaged with the middle gear is operated to rotate the other gear to open/close both intake grilles (upper and lower grilles). Such a mechanism has been known (for example, see Patent Document 1: JP-A 2003-156225).
- The mechanism of Patent Document 1 is configured to transmit the driving force from the motor to the intake grilles via the gears. Therefore, in combination of the intake grilles with the air conditioner body, the gears must be assembled on certain engagement. For that purpose, the intake grilles require accuracy of attaching locations, whichmakes it difficult to implement assembling on production and assembling at the time of internal repairing and checking. In addition, the need for a plurality of gears and racks complicates assembling and increases costs.
- In order to reduce a thickness of an air conditioner in consideration of such the point, the present invention provides an air conditioner capable of closing a front panel when the air conditioner is not used and opening the front panel to suck air sufficientlywhen the air conditioner is operated. The front panel is driven not by combined gears but by application of a simple mechanism. In addition, the front panel is configured removable and easily assembled to provide an air conditioner that is easy for assembling on production and internal repairing and checking.
- In a first aspect the invention provides an air conditioner, which comprises an air conditioner body housing a heat exchanger and a fan therein, and a front panel covering the front of the air conditioner body. The front panel is supported on the air conditioner body as reciprocally movable by a drive mechanism between a first state closed and a second state open to ensure a certain air intake. The drive mechanism includes a drive cum member provided on the air conditioner body and operative to reciprocally swing by an electrically driven mechanism, and a follower cum member provided to impinge on the drive cum member and operative to reciprocally swing by the drive cum member.
- In a second aspect of the invention, the front panel is removable from the air conditioner body together with the follower cum member.
- In a third aspect of the invention, the air conditioner body and the front panel are linked to each other by the left and right operation arms pivoted at the front of the air conditioner body and the rear of the front panel. A follower cum surface is formed in the rear surface of at least one of the operation arms. A drive cum surface impinging on the follower cum surface is formed on the front of the drive cum member, and the drive cum member operative to reciprocally turn by the electrically driven mechanism is provided on the air conditioner body.
- In a fourth aspect of the invention, a base member is provided behind the front panel as removably supported on the front of the air conditioner body. The base member and the front panel are linked and supported to each other via the left and right operation arms pivoted at the base member and the front panel.
- In a fifth aspect of the invention, the front panel and the base member are detachably attached in set to the air conditioner body while linked by the left and right operation arms.
- In a sixth aspect of the invention, the front panel is controlled to turn into the first state while the air conditioner is not operated and to turn into the second state while the air conditioner is operated.
- In the present invention, the driving force from the electrically driven mechanism for opening/closing the front panel is transmittedvia impingement between the drive cum member and the follower cum member. Therefore, in comparison with the power transmission system with gear engagement , the driving force transmission mechanism has a larger margin of combination. Accordingly, assembling on production and assembling at the time of internal repairing and checking can be performed easily. This is suitable for configuring the opening/closing front panel to be removable from the air conditioner body.
