Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a dehumidifier main body with an intake port for sucking indoor air, and an evaporator for cooling and dehumidifying the indoor air sucked from the intake port in the dehumidifier main body. The present invention relates to a dehumidifier provided with a condenser that heats air that has been dehumidified by an evaporator, and a blower that blows dry air that has been heated by the condenser through an outlet provided in the dehumidifier body.

[0002]

2. Description of the Related Art An example of a conventional dehumidifier will be described with reference to FIG. In the conventional dehumidifier, the dehumidifier main body 21 is provided with an intake port 22 for sucking indoor air, and the dehumidifier main body 21 is provided with an evaporator 23 for cooling and dehumidifying the indoor air sucked from the intake port 22. A condenser 24 for heating the air that has been cooled and dehumidified by the evaporator 23 is provided, and the dry air heated by the condenser 24 is provided in the dehumidifier main body 21 with a blowout port 25, and the dry air is blown out from the blowout port 25. A sirocco fan 26, which is a blower, was provided.

The evaporator 23 in the dehumidifier body 21,
A drain pan 27 is provided below the condenser 24 and the like for receiving water droplets that are condensed and drip on the surface of the evaporator 23, and a drain tank 28 that stores the water droplets collected by the drain pan 27 is provided.
A compressor 28 was provided below the drain pan 27.

Then, the dehumidifier sucks indoor air containing moisture from the intake port 22 and cools the sucked indoor air by the evaporator 23. At this time, the water in the indoor air is condensed on the surface of the evaporator 23 to form water droplets, which adhere to the surface of the evaporator 23 and drop on the drain pan 27, whereby the indoor air is dehumidified. Then, the dehumidified air is heated by the condenser 24 and becomes dry air, and is blown out into the room from the blowout port 25 by the sirocco fan 26.

[0005]

With the dehumidifier having the above-mentioned structure, the dry air blown out from the outlet is blown out in only one direction, so that the dry air is blown throughout the room in which the dehumidifier is placed. Was difficult to spread, and it was not possible to dehumidify the room efficiently. Further, in order to dry the clothes using the dehumidifier, when the clothes are dried above the dehumidifier, the dry air blown from the outlet of the dehumidifier hits only a part of the clothes, However, there is a problem that the clothes cannot be dried uniformly and unevenness occurs in the dryness of the clothes.

The dehumidifier of the present invention efficiently dehumidifies the inside of the room by blowing dry air blown out from the outlet of the dehumidifier in multiple directions, and evenly dries clothes when used for drying clothes. The purpose is.

[0007]

The dehumidifier of the present invention has been made in order to achieve the above-mentioned object. The dehumidifier main body is provided with an intake port for sucking indoor air, and the dehumidifier main body is provided with the intake air. An evaporator for cooling and dehumidifying the indoor air sucked from the mouth is provided, and a condenser for heating the air cooled and dehumidified by the evaporator is provided, and the dry air heated by the condenser is provided in the dehumidifier body. An air blower for blowing out from the blower outlet is provided, a wind direction plate is rotatably provided inside the blower outlet of the dehumidifier main body for blowing out dry air in multiple directions, and a drive device for rotationally driving the wind direction plate is provided.

[0008]

The above dehumidifier cools and dehumidifies the indoor air sucked from the intake port with the evaporator, heats the cooled and dehumidified air with the condenser to dry the air, and the dry air is blown into the room through the blower. Blown out. At this time, since the wind direction plate is rotationally driven by the drive device, the directions in which the dry air is blown out are changed in multiple directions, and the dry air is blown out uniformly into the room.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the dehumidifier of the present invention will be described with reference to FIGS. In the dehumidifier of the present invention, the dehumidifier main body 1 is provided with an intake port 2 for sucking indoor air, and the dehumidifier main body 1 is provided with an evaporator 3 for cooling and dehumidifying the indoor air sucked from the intake port 2. A condenser 4 for heating the air dehumidified by the evaporator 3 is provided, and a sirocco fan 6 which is a blower for blowing the dry air heated by the condenser 4 from an outlet 5 provided in the dehumidifier body 1 is provided. Provided,
Inside the outlet 5 of the dehumidifier main body 1, a wind direction plate 7 is rotatably provided in order to blow dry air in multiple directions, and a motor 8 which is a drive device for rotationally driving the wind direction plate 7 is provided.

The wind direction plate 7 is formed in a disk shape, and the wind direction plate 7 is provided on a rotary shaft 9 with an inclination with respect to the rotary shaft 9, and the rotary shaft 9 drives the motor 8. It is connected to a shaft 10 and is configured to rotate the wind direction plate 7 by the motor 8.

A drain pan 11 for receiving water droplets that condensate and drip on the surface of the evaporator 3 is provided below the evaporator 3 and the condenser 4 in the dehumidifier body 1, and the water droplets collected by the drain pan 11 are stored. A drain tank 12 is provided, and a compressor 14 is provided below the drain pan 13.

[0012] The dehumidifier sucks indoor air containing moisture from the intake port 2 and cools the sucked indoor air by the evaporator 3. At this time, the water in the room air is condensed on the surface of the evaporator 3 to form water drops, which are attached to the drain pan 11 to be dehumidified. The dehumidified air is heated by the condenser 4 to become dry air, which is blown out into the room from the air outlet 5 by the sirocco fan 6. At this time, since the wind direction plate 7 is rotationally driven by the motor 8, the directions in which the dry air is blown out are changed in multiple directions, and the dry air is blown out uniformly into the room.

The case of drying clothes using the above dehumidifier will be described with reference to FIGS. 3 and 4. First,
Towel 1, towel 2 and towel 3 are dried 75 cm above the dehumidifier with a distance of 25 cm between each towel. At this time, 30 g of water is added to the towel with a weight of 47 g when the towel is dried.
When the experiment was conducted in a 6-tatami-mat Japanese room at room temperature of about 22 ° C., the relationship between the moisture reduction rate of towel 1 and the drying time is
As shown by the solid line in (a), there is almost no difference from the one dried by the conventional dehumidifier shown by the broken line in Fig. 4 (a), but Fig. 4 (b), (c) For Towel 2 and Towel 3, the solid line showing the relationship between the moisture reduction rate and the drying time of the towel dried by the dehumidifier of the present invention is faster than the broken line showing the one dried by the conventional dehumidifier. You can see that the towels dry in time. The water reduction rate in FIG. 4 can be calculated by the following mathematical expression 1, and the value obtained by the following mathematical expression is shown in FIG.

[0014]

[Equation 1]

Therefore, as can be seen from the above, in the dehumidifier of the present invention, the dry air blown out from the blowout port 5 is blown out in multiple directions by the wind direction plate 7, and is uniformly applied to the towel 1, towel 2 and towel 3. Therefore, the towel can be dried evenly.

[0016]

Since the dehumidifier of the present invention blows dry air in multiple directions by rotating the wind direction plate, it can efficiently dehumidify the interior of the room, and when used for drying clothes. Therefore, clothes can be dried uniformly without unevenness in drying.
