Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner mainly used in a room with a small installation space such as a toilet.
[0002]
[Prior art]
As this type of air conditioner, there is an air conditioner for toilets that cools a condenser with water in a cistern (low tank, flush tank) as disclosed in JP-A-58-26941. The main body of the air conditioner is installed at the upper part of the cistern, and the cooler of the evaporator is blown out from the outlet through the blower to cool the room. On the other hand, the heat of the condenser is taken away by sensible heat and latent heat of evaporation by sprinkling water in the cistern pumped up by the pump, and the hot and humid air is drained to the toilet through the drain pipe.
[0003]
Another example is Japanese Utility Model Laid-Open No. 4-103525. This is because a cooling water storage tank that cools the condenser is attached to the air conditioner body, tap water is pumped from a spare water supply port of the systern, and cooling water is supplied to this cooling water storage tank. It is set as the structure which provides a water supply equipment part.
[0004]
[Problems to be solved by the invention]
However, in the former configuration, it is installed at the top of the cistern and drains hot and humid air to the toilet bowl. Become. (2) In the case of retrofitting, the air conditioner body is required to have a shape suitable for a wide variety of toilets. (3) It is difficult to attach to an installation place other than the upper part of the cistern. Have many issues.
[0005]
Moreover, in the latter structure, when the water supply facility was inadequate, there existed problems, such as the stop of the operation | movement by water leak, and the inside of a toilet getting wet.
[0006]
An object of the present invention is to solve such a conventional problem, and an object thereof is to provide an air conditioner that is easy to be retrofitted and that prevents operation stoppage due to water leakage and wetting of the floor surface.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a compressor, a condenser that cools a refrigerant using liquid supplied from outside the apparatus main body by liquid supply means, a decompression mechanism, an evaporator, and an evaporator for the evaporator. In addition to providing a blower, an inlet pipe connection part and an outlet pipe connection part for the cooling liquid of the condenser and a power supply connection part for the liquid supply means are provided on the same surface of the apparatus main body.

In addition, the center of gravity of the air conditioner main body 1 can be set to the lowest position, and it is difficult to fall down and can be stably placed on the floor surface.
[0019]
The refrigerant discharged from the compressor 11 enters the water-cooled condenser 12 and exchanges heat. Then, the refrigerant enters the evaporator 13 through the throttle 16 that is a decompression mechanism, and exchanges heat to return to the compressor 11. It is composed.
[0020]
The cooling water 18 for cooling the water-cooled condenser 12 is stored in a cooling water container (tank) 17 provided outside the water-cooled air conditioner body 1, and a circulation pump (liquid) is provided in the cooling water container 17. Supply means) 15 is provided. The inlet pipe connection part 2 and the outlet pipe connection part 3 are provided above the water surface of the cooling water 18. The cooling water 18 passes through the pipe 21 a in the direction of the arrow by the circulation pump 15, passes through the pipe 21 b through the inlet pipe connection 2, and enters the water-cooled condenser 12. After cooling the refrigerant in the water-cooled condenser 12, the heated cooling water passes through the pipe 22b, passes through the pipe 22a via the outlet pipe connecting portion 3, flows out in the direction of the arrow, and enters the cooling water container 17 again. Return.
[0021]
There is an outlet 4 that supplies power to the main body 1, and supplies power to the main body 1. Reference numeral 5 denotes a circulation pump cord for supplying power to the circulation pump 15, which is connected to the power supply connecting portion 6 and supplies power to the circulation pump.
[0022]
A drain pan 13a or a drain tank is provided under the evaporator 13, and the drain pan 13a has a function of receiving drainage and receiving water leaked from the inlet pipe connecting portion 2 or the outlet pipe connecting portion 3.

[0023]
3 is a cross-sectional view taken along the line AA of FIG. 1, and the power supply connecting portion 6 for supplying power to the circulation pump 15 is flush with the inlet pipe connecting portion 2 and the outlet pipe connecting portion 3 of the concave portion 1 a of the main body 1, and Since it is provided in the upper part, the other surface can be in close contact with the wall surface, and can be installed in a manner that does not easily fall over. Further, it is possible to prevent a failure of the main body caused by water flowing from the inlet pipe connection part 2 and the outlet pipe connection part 3 to the power supply connection part 6, and the water transmitted through the circulation pump cord 5 flows to the cooling water container 17. It does not drip before and wets the floor. Further, since the power supply connecting portion 6 is not easily detached, it is possible to stably supply cold air to the user.
[0024]
In addition, even in the cooling water container 17 (for example, a flush tank in a toilet) that has already been installed, only the circulation pump 15 is immersed in the cooling water container 17 and the cooling water pipes 21a and 22a are connected to the priming water. The air conditioner can be easily attached.
[0025]
As shown in FIG. 2, the air flows in from the W1 side on the windward side of the evaporator 12, passes through the evaporator 12, is cooled, and flows out from the outlet 7 to the W2 side.
[0026]
Next, the water-cooled condenser 12 will be described with reference to FIG. The water-cooled condenser 12 has a double-pipe heat exchange system, and includes an inner tube 52 and an outer tube 55. The refrigerant flows in the inner tube 52 as indicated by an arrow A1, and is formed by the outer tube 55 and the inner tube 52. The cooling water flows in the direction of arrow B2 through the donut-shaped flow path. A water-cooled condenser 12 is formed by bending the tube into a curved shape.
[0027]
Next, the cold air outlet will be described. FIG. 5 shows the relationship between the person 96 sitting on the toilet bowl 95 and the present air conditioner. The water-cooled air conditioner main body 1 is installed obliquely behind the person 96 and cool air is applied to the vicinity of the shoulder 97. The height of the air outlet 7 is set to be between 700 mm and 900 mm from the floor surface. With this configuration, when a person sits on a Western-style toilet seat, the cool airflow 98 can be easily applied to a place where the person feels cool, for example, near the shoulder 97.
[0028]
In the above embodiment, the condenser 13 is water-cooled and water is used as a cooling liquid. However, a liquid other than water may be used as long as it has a cooling function and does not hinder handling.
[0029]
