DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for blowing cool air obtained by a cool air dehumidifier from a cool air outlet of a front plate of a frame and guiding the cool air to an arbitrary place using a duct.

[0002]

2. Description of the Related Art A conventional cold air dehumidifier includes a compressor, a condenser, and an evaporator in a frame body. The compressor compresses a refrigerant, converts the refrigerant into a high-temperature, high-pressure gas, and sends it to the condenser. The refrigerant is cooled and liquefied by the condenser. . Then, the liquid refrigerant is sent to an evaporator via a capillary to cool the surroundings when vaporized, and the vaporized refrigerant gas is returned to the compressor. Therefore, the air passing through the condenser becomes hot due to the heat of the refrigerant, while the air passing through the evaporator becomes cold due to the heat of vaporization.

[0003] A cool air fan is provided in the frame of the cool air dehumidifier, and a cool air outlet is provided in a front plate of the frame, and a scroll of the cool air fan is connected to the cool air outlet. Air passing through the evaporator and entering the inside of the frame is sucked by the cool air fan and blown out from the cool air outlet. Also, a horizontal louver and a vertical louver for changing the direction of blowing the cool air are attached to the cool air outlet, and the direction of the cool air blown out from the cool air outlet can be changed vertically and horizontally.

[0004] By the way, it is difficult to change the blowing direction of the cold air by the louver only by swinging the wind direction up, down, left and right. For this reason, a duct made of a flexible material is attached to the cool air outlet of the front plate of the frame, and the cool air is guided into the duct so that the cool air can be blown out toward the end of the movable portion of the duct in a desired direction. it can.

[0005]

When the duct is mounted on the cool air outlet of the front plate of the frame, the structure inside the frame as the cool air dehumidifier can be almost shared, so that the surface of the front plate of the frame is removed. It is necessary to provide a screw hole for mounting the duct, and this mounting screw does not cause much trouble when cold air is sent using the duct. However, the formation of several screw holes on the surface of the front plate when the duct was removed was quite annoying, and it was impossible to use the front plate in common.

For this reason, even if the structure inside the frame is common,
With the entire front plate as a replacement part, two types of front plates when using the duct and when not using the duct are prepared, and rearranged as appropriate for each application. However, changing one set at the time of shipment afterwards was a rather cumbersome operation, and sometimes the other front plate was lost during one operation, so it was not a perfect method. .

[0007]

According to the present invention for solving the above-mentioned problems, a cold air outlet 2 for blowing dehumidified cool air is provided on a front plate 1a of a frame 1, and a cold air outlet is provided in the frame 1. In the cool air dehumidifier provided with the cool air fan 3 communicating with the cold air blower 2, the cool air outlet 2 is formed in a vertically long shape in which a long vertical louver 4 can be arranged, and a part of the lower part of the cool air outlet 2 is located at the vertical louver 4 position. The scroll 3a of the cold air fan 3 is connected to the upper and side portions of the cool air outlet 2 and the flat portion 2a, and the scroll 3a is located deeper than the vertical louver 4 position. A plurality of horizontal louvers 5 in front of the
A duct 6 is provided to cover the entire front surface of the cool air outlet 2, a screw hole 7 is provided in a plane portion 2a behind the vertical louver 4, and
A locking portion 8 is formed on an upper wall extending from the scroll 3a to the cool air outlet 2, and a locking means 9 having a protrusion 9a facing upward at a tip thereof is formed at an upper portion of the duct 6, and a lower portion of the duct 6 is formed. Is provided with a projection 10 reaching the plane portion 2a. The projection 9a and the locking portion 8 are fitted while moving the duct 6 upward along the cold air outlet 2, and the projection 9a and the locking portion 8 At the fitting position, the mounting screw 11 provided on the projection 10 is screwed and fixed to the screw hole 7, and the screw hole is shaded by the vertical duct and is almost inconspicuous, so that the screw hole 7 is finished neatly.

Further, locking holes 12 are provided above and below the cold air outlet 2, and the ends of the vertical louvers 4 are fitted into the locking holes 12, and the vertical louvers 4 are formed of an elastic material. If the vertical louver 4 is removed by using the elasticity at the time of installation, the resistance of the cool air blown from the cool air fan is reduced, so that the blowing force of the wind is increased, and a large amount of wind is sent using the duct even at a distant place. It was something that could be done.

[0009]

The cold air outlet 2 of the front plate 1a of the frame 1 of the present invention.
Has a vertical louver 4 attached to it to form a vertically long shape.
In addition, a flat portion 2a is provided in the lower part of the vertical louver 4 below the cool air outlet 2. Therefore, if the flat portion 2a is not the surface of the front plate 1a but is the shadow of the vertical louver 4, the screw hole 7
Is almost inconspicuous even when the cooling air dehumidifier is provided, and the cold air dehumidifier can be used without any change from the conventional one.

[0010] An engaging portion 8 is provided on an upper wall of a connecting portion from the scroll 3a of the cool air fan 3 to the cool air outlet 2 of the present invention, and an engaging portion extending from a duct 6 covering the cool air outlet 2 is provided. A projection 9a pointing upward is provided at the tip of the means 9, and a projection 10 facing the flat portion 2a is provided below the duct 6. Therefore, if the duct 6 is moved upward with the cold air outlet 2 attached, the protrusion 9a and the locking portion 8 are locked, and the protrusion 10 and the screw hole 7 are aligned with each other. If the mounting screw 11 is screwed from 10 to the screw hole 7, the duct 6 can be fixed to the cool air outlet 2.

The locking means 9 and the projection 9a are located between the vertical louvers 4, but when the duct 6 is used, the vertical and horizontal louvers 4 and 5 provide resistance to air flow. Normally, air is drawn out from the duct 6 upward or downward from the design of the frame 1, and there is almost no need for the vertical louvers 4 for changing the wind direction to the left and right. Therefore,
If the vertical louver 4 is made of an elastic material such as a synthetic resin so that the vertical louver 4 can be removed when the duct 6 is attached, the amount of air blown out of the duct 6 can be increased.
