Description

  The present invention relates to a louver structure for changing a wind direction provided at an outlet of an air conditioner such as a dehumidifier.

  Conventionally, this type has a plurality of left and right wind direction plates in the louver frame, a right connecting plate in which the right right wind direction plate is positioned in parallel, and a left connecting plate in which the left left wind direction plate is positioned in parallel. A plate and a central connecting plate that connects the right wind plate and the left wind plate on the center side are provided, and the blowing direction in the left-right direction can be changed in the diffusion direction from the central concentration to the left-right direction. (For example, see Patent Document 1)

JP 2012-159234 A

  By the way, in this prior art, as the number of contact portions that are transmitted through the wind direction plate and the connecting plate increases, a load is generated on the rotating shaft of the wind direction plate that transmits force due to transmission loss such as friction. For this reason, there is no problem if the direction of the left and right wind direction plates is changed manually, but when rotation durability of tens of thousands of times or more is required by automatic rotation operation such as swing operation using a louver motor, Due to the transmission loss, there was a risk that the left and right wind direction plates would not move due to a failure in the connecting part of the left and right wind direction plates and connecting plates.

This invention pays attention to this point, and in order to solve the above-mentioned drawbacks, in particular, the configuration is such that an evaporator, a condenser, and a blower fan are arranged between a suction port and a blower outlet provided in the frame body to form a blower path. The compressor and the evaporator, the condenser and the like are connected by refrigerant piping to form a refrigeration circuit, and after the air sucked from the suction port by the operation of the blower fan is cooled and condensed by the evaporator, In the air conditioner that heats in the condenser and discharges dry air from the air outlet , the air outlet opens upward or rearward of the frame body, and the air outlet has a bearing portion provided on a side surface of the air outlet. And the upper and lower louver motors, the upper surface of the frame body is substantially flat, the louver frame body is set to a position in the blowing direction to the rear side, the rear blowing position for blowing the air sent from the blower fan side to the rear from the blower outlet, and the louver frame The upper surface of the frame by rotating the body Open provided rotatable louver frame between the blower fan side of the direction blowout position on blowing drying air upwards, the louver frame includes a lower louver-shaped cross-section U, the lower The left and right wind direction plates are arranged in parallel with the lower surface of the louver and provided with an upper louver covering the upper part, and are arranged between the upper louver and the lower louver so as to be movable left and right. A left and right wind direction plate motor having a concentric rotation axis is provided with one of the plates, and the left and right wind direction plate is attached to a first left and right wind direction plate located at a right end of the louver frame body, and the first connecting plate is connected to the first left and right wind direction plate motor . A central connecting plate and a left connecting plate are provided that interlock the second left and right wind direction plates adjacent to the left and right wind direction plates, and individually operate the third left and right wind direction plates by rotating the second left and right wind direction plates. It is a thing.

According to the present invention, it is possible to transmit the motion of the left and right wind direction motors from the first left and right wind direction plates at the right end to the fourth left and right wind direction plates at the left end by using the two connecting plates, which is smaller. Since all the left and right wind direction plates can be rotated by the motor torque, the durability performance of the drive structure of the left and right wind direction plates is improved.
