DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for dehumidifying indoor air.

[0002]

2. Description of the Related Art Conventionally, as this type of air conditioner, an evaporator for dehumidifying moisture in room air is provided in a main body case as described in Japanese Utility Model Publication No. 58-50183.
A dehumidifier is known in which a tank for storing dehumidified moisture in room air is provided below the evaporator, and a concave handle is provided on the front upper side of the tank at the back.

[0003] However, the conventional air conditioner has a problem that the drawer of the tank becomes unstable when dehumidified water is accumulated in the tank because the handle is provided on the upper part.

As a countermeasure for this, Japanese Utility Model Application Laid-Open No. 58-67240 has been proposed.
In the publication, a handle provided with a hand insertion opening at the bottom of the tank and an upwardly concave recess connected to the back of the hand insertion opening is shown, but the hand insertion opening is enlarged to make it easier to hold. Therefore, there is a problem that the capacity of the tank is reduced accordingly.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an air conditioner that can easily attach and detach a tank and can reduce a decrease in the capacity of the tank.

[0006]

Means for solving the above problem is to provide an evaporator for cooling indoor air and removing moisture from the indoor air in a main body case, and storing the moisture removed by the evaporator. In an air conditioner in which a tank is detachably provided at a lower portion of a main body case, the tank is formed with a hand insertion recess extending from a lower front surface to a bottom surface, and is recessed upward in the back of the hand insertion recess. A concave portion is continuously provided, and a hand guide surface lower than the bottom surface of the tank is formed on a surface of the main body case facing the concave portion for manual insertion. This allows the hand to be guided to the recess by the hand guide surface when attaching and detaching the tank, so that the hand can be easily inserted into the recess through the hand insertion recess. In addition, since the hand guide surface is lower than the bottom surface of the tank, the hand insertion recess can be made smaller, so that the capacity of the tank can be increased.

[0007] In the above configuration, it is preferable that the hand guide surface is an inclined surface having a downward slope toward the front side of the main body case. Thereby, the hand can be more easily inserted into the concave portion by the inclined surface.

It is preferable that the manual insertion recess is provided only at a substantially central portion of a lower portion of the tank. Thereby, the substantially central portion of the lower portion of the tank is supported, and the tank can be taken out stably.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings.

As shown in FIGS. 1 and 2, an air conditioner (here, a dehumidifier) of the present embodiment has a front case
And the rear case 2 are covered by a main body case 3 formed by combining the two. The front case 1 has a suction port 4 for sucking room air at an upper portion of the front surface, and an opening portion for inserting and removing a tank 5 at a lower right portion. On the upper surface of the front case 1, there is provided an operation panel 6 on which a switch SW for driving and stopping the main body, an indicator LED indicating the operation state thereof, and the like are arranged. The upper surface of the front case 1 has an inclined surface rising from the upper edge of the front surface toward the center in the front-rear direction of the upper surface of the main body case 3, and a piece 7A of the handle 7 is formed at the center position.

Rear case 2 combined with front case 1
Has an outlet 8 for dehumidified air formed on its upper surface,
Like the front case 1, the rear case smoothly rises from the upper edge of the rear surface and has an inclined surface extending to the center in the front-rear direction of the upper surface of the main body case 3, and the other side 7 </ b> B of the handle 7 is formed at the center position.

The relationship between the dehumidified air outlet 8 provided on the upper surface of the rear case 2 and the handle 7 is as shown in FIG.
The arrangement is such that the outlet 8 is formed at a position lower than the imaginary line 9 connecting the handle 7 and the upper edge of the rear surface of the rear case 2.

The inside of a main body case 3 composed of a front case 1 and a rear case 2 has an evaporator 1
0, a condenser 11, a fan motor 12, and a fan 13 are sequentially arranged, while a compressor 14 is arranged at a lower left position in front of the storage tank 5, avoiding the storage tank 5.

The dehumidifier of this embodiment has such a structure. When the switch SW on the operation panel 6 is turned on, the operation starts, and when the compressor 14 is driven, the refrigerant is compressed via the evaporator 10 and the condenser 11. A refrigerant circulation path returning to the machine 14 is formed, and the evaporator 10 performs a heat absorbing operation and the condenser 11 performs a heat releasing operation. Simultaneously, the humid air in the room is taken into the inside of the main body from the suction port 4 by driving the fan motor 12 as shown by the arrow in the drawing, and passes through the evaporator 10 after dust is removed by an air filter (not shown). It is cooled and dehumidified. The cool air after dehumidification is supplied to the condenser 11
After being heated to room temperature, the air is returned from the outlet 8 to the room.

By the way, when the water passes through the evaporator 10, the water removed from the room air becomes water droplets, falls into the drain pan 21, and flows down to the tank 5 through a drain hole 22 formed at the bottom.

As a result, when the tank 5 is filled with the dehumidified water, the float 23 is disengaged from the lever 24, the liquid level switch 25 is turned off, the operation is stopped, and the dehumidified water drainage request provided on the operation panel 6 is provided. Turn on the display.

Therefore, the user pulls out the tank 5 from the main body while watching the lighting of the dehumidification water drainage demand indicator. In order to make the tank 5 containing the dehumidification water easy to pull out from the main body, the following structure is used. I have.

As shown in FIGS. 3 and 4, a hand insertion concave portion 26a extending from the lower front surface to the bottom surface of the tank 5 is formed in a substantially U-shaped lower portion at the substantially central portion of the lower front surface of the tank 5. A concave portion 26 that is depressed upward is provided continuously behind the concave portion 26a for hand insertion as a handhold portion. On the other hand, the lower surface 27 of the front surface of the front case 1 facing the concave portion 26a for hand insertion is lower than the bottom surface of the tank 5 and is inclined downward toward the front surface of the front case 1. The hand guide surface guides the hand to the concave portion 26 when the hand is inserted into the recess 26.

When the tank 5 is pulled out, the hand insertion recess 26
This is performed by inserting a hand from the space formed between a and the hand guide surface 27 and grasping between the wall surface on the near side of the concave portion 26 and the front surface of the tank 5 facing this wall surface. At this time, since the hand can be guided to the concave portion 26 by the hand guide surface 27, the concave portion 2
6 can be easily inserted, and the tank 5 can be easily attached and detached.

Further, the front lower surface 27 of the front case 1 facing the hand insertion recess 26a is lower than the bottom surface of the tank, so that the hand insertion recess 26a of the tank 5 is not so high as shown in FIG. The tank capacity can be increased without going up. By forming the concave portion 26 only in the substantially central portion of the lower portion of the front surface of the tank 5, the substantially central portion of the lower portion of the tank 5 is supported, and the tank 5 can be stably pulled out.

[0021]

According to the first aspect of the present invention, the hand can be guided to the concave portion by the hand guide surface when the tank is attached or detached. Can be done. In addition, since the hand guide surface is lower than the bottom surface of the tank, the size of the hand insertion recess can be reduced, so that the capacity of the tank can be increased.

Further, according to the second aspect, the hand can be more easily inserted into the concave portion by the inclined surface, so that the attaching / detaching operation of the tank can be performed more easily.

According to the third aspect of the present invention, the tank can be taken out in a stable state by supporting substantially the center of the lower part of the tank.
