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, in this type of apparatus, a plurality of left and right wind direction plates connected by connecting plates are provided in a louver frame provided in the air outlet, and left and right wind direction motors for rotating the left and right wind direction plates, and washing An infrared sensor for detecting the temperature of an object or the like is provided at the center of the louver frame. And the rotation of the left and right wind direction motor enables the change of the wind direction of the blown wind in the left and right direction automatically. (For example, see Patent Document 1)

JP 2011-158136 A

  By the way, in this conventional one, since the left and right wind direction motors and infrared sensors are provided so as to block the relatively strong wind speed at the center of the louver frame, the left and right wind direction motors and infrared sensors serve as blowing resistance. In addition, there is a fear that making the air outlet as a whole hinders compactification or causes noise due to compactification.

  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 blower outlet, the blower fan is formed of a sirocco fan having a rotation axis substantially perpendicular to the front surface of the frame body, and surrounds the blower fan. A casing for guiding the air flow to the air outlet is provided, the air fan is located slightly on the right side from the center of the casing, the stabilizer is located above the air fan, the air guide is located on the left side of the stabilizer, and the air outlet is above the frame Or A louver frame that opens in the direction of the air and allows the air flow to vary between the upper direction of the frame body and the rear direction of the frame body is rotatably attached to the air outlet, and this louver frame body has a U-shaped cross section. The lower louver and the lower surface of the lower louver are substantially parallel and spaced apart, and an upper louver that covers the upper part is provided. A plurality of left and right wind direction plates, and a left and right wind direction plate positioned at the right end of the left and right wind direction plates and a left and right wind direction motor having a concentric rotation axis.

  According to the present invention, since the left and right wind direction motors are provided at the right end in the louver frame body having the weakest blown air speed at the blowout port, the blowout port can be made compact, and the left and right wind direction motors become resistance. The blowing noise generated in the can be reduced.

Therefore, the right and left wind direction motors 18 are positioned at the right end of the outlet 6 located on the right side of the stabilizer 46. Since the air volume of the part is relatively weak, the influence on the overall air flow is extremely small.
In addition, a partition plate 48 having an air outlet is provided in the center between the condenser 40 and the fan 41 in order to efficiently guide the air to the fan 41, and a drain pan 49 for receiving condensed water is provided below the evaporator 9. Is provided.
Reference numeral 50 denotes a drainage channel having one end connected to the bottom surface of the drain pan 49 and the other positioned at the upper portion of the drain tank 51, and guides the condensed water collected in the drain pan 49 to the drain tank 51.

  52 is a heater provided in the ventilation path 43 inside the blower outlet 6 and prevents the efficiency of dehumidification from lowering at room temperature when clothes are dried or during the winter period. It is about 500W. 53 is a U-shaped handle for transporting the dehumidifier, and is housed behind the upper surface of the dehumidifier. An operation unit 54 is provided at a front portion of the upper surface of the dehumidifier and includes switches such as an operation switch (not shown) and display lamps such as an operation lamp (not shown). A compressor 55 is fixed to the bottom plate 2.

  FIG. 3 shows a state in which the left and right wind direction plates 17 are in parallel, and if the left and right wind direction motor 18 is driven from this state, the connecting plates 25, 30 and 35 move in the direction of the arrows, and the blown air is discharged as shown in FIG. The left and right wind direction plates can be directed in the left and right direction so as to diffuse, and 2 for transmitting the force of the left and right wind direction motor 18 from the first right and left wind direction plate 23 at the right end to the fourth left and right wind direction plate 37 at the left end. The movement can be transmitted by the individual connecting plates 25 and 35, and all the left and right wind direction plates 17 can be rotated with a smaller motor torque, so that the driving structure of the left and right wind direction plates 17 is durable. The performance is improved.

Thus, since the right and left wind direction motor 18 is provided at the right end in the louver frame 9 having the weakest blown wind speed at the blowout port 6, the blowout port 6 can be made compact. The blowing noise generated by becoming a resistance can be reduced.
Further, by providing the left / right wind direction motor 18 integrally with the left / right wind direction plate 23 in the louver frame 9, the number of parts can be reduced, and the manufacturing cost can be reduced.
