Abstract

PURPOSE:To place the side surface of a watercooler in close contact with a wall surface or the like and enhance the efficiency of installation by providing an open air suction port to the lower part of a front surface of the watercooler. CONSTITUTION:A waste water tank 20 forms an open air suction port 22 which meets with a notched and recessed part 21 between the waste tank 20 and a bottom material 2 of a watercooler 1 as it is laid out at a specified position of the front of the watercooler 1. This open air suction port 22 is communicated with the interior of the watercooler 1. When starting a fan 6 in a refrigeration cycle, the open air flows into the watercooler 1 from the open air suction port 22. The open air which has flown into the watercooler 1 flows at the rear side in the watercooler 1 and cools a pressure apparatus 4. After having cooled the apparatus, the open air is heat-exchanged when passing through a condenser 5 and then discharged outside from a discharge port 14. Since there is no need for installing an open air suction port, such as louver to the side surface of a bonnet 3, it is possible to install the cooler in such a fashion that the side surface may be placed in close contact with a wall surface and reduce an installation space and incorporate the cooler into a system unit easily as well.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water cooler which can be installed in close contact with a side wall of a wall or the like and can be incorporated into a system unit.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional water chiller comprises a water chiller body 1 in which a box-shaped cabinet 3 is mounted on a bottom member 2, and a chiller cycle is provided in the water chiller body 1. The compressor 4, the condenser 5, the blower 6 and the cooling tank 7 cooled by the condenser 5 are arranged. And
An upper lid 8 is attached to the upper opening of the cooling tank 7 provided in the water cooler body 1. Further, a recess 10 is formed by the front panel 9 in the front surface of the chiller body 1, a cold water faucet 11 is arranged at the upper end of the recess 10, and a bottom surface of the recess 10 is provided. The drainage tank 12 is arranged.

On the other hand, an outside air suction port 13 is provided on the side surface of the cabinet 3, and an outlet port 14 is provided on the back surface of the cabinet 3, so that the air sucked from the outside air suction port 13 provided on the side surface. Through the condenser 5
The heat-exchanged air is discharged from the outlet 14 to the outside.

[0004]

In the conventional water chiller, the outside air suction port is provided on the side surface of the cabinet.
Since it has to be arranged with a space of 0 cm or more, there is a problem that installation efficiency is poor due to an increase in installation area. Particularly, in recent years, for example, a water cooler installed in a restaurant or the like has a large installation space and is increasingly housed in a system unit. Therefore, deterioration of installation efficiency is a serious problem.

The present invention has been made in view of the above points, and an object of the present invention is to provide a chiller capable of improving the installability by bringing the side surface of the main body into close contact with a wall surface or the like.

[0006]

According to the chiller of the present invention, a compressor, a condenser, a blower and a cooling tank constituting a refrigeration cycle are arranged inside the chiller body, and a chiller tank is provided on the front face of the chiller body. A faucet and a drainage tank are arranged below the faucet, and an outside air suction port is provided at a lower part of the front surface of the chiller body.

Further, the chiller of the present invention has an outside air suction port,
It is characterized in that a drainage tank having a cutout recess formed at the rear end of the lower surface is formed so that the cutout recess is spaced from the front surface of the chiller body.

[0008]

In the water chiller of the present invention, the outside air suction port is provided in the lower front portion of the water chiller main body, so that the side surface of the water chiller main body can be installed in close contact with the wall surface, etc. It becomes possible. Further, since the discharge port is usually provided on the back surface of the chiller body, the outside air flows through the inside of the chiller machine from the front side to the back side by providing the outside air suction port on the lower part of the front side of the chiller machine body. Therefore, the compressor can be cooled.

Further, in the cooler of the present invention, since the notched concave portion provided on the lower surface of the drainage tank is used as the outside air suction port, the outside air suction port is not exposed to the outside and the appearance is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, the same members as those in FIG. 3 are designated by the same reference numerals.

In FIG. 1, reference numeral 20 indicates a drainage tank, and an end portion of the lower surface of the drainage tank 20 on the chiller body 1 side is cut away from one side to the other side as shown in FIG. A cutout recess 21 is formed. This drain tank 20
Is placed at a predetermined position on the front surface of the water cooler body 1,
An outside air suction port 22 corresponding to the cutout recess 21 is formed between the drainage tank 20 and the bottom member 2 of the water cooler body 1. The outside air suction port 22 communicates with the inside of the water cooler body 1.

On the other hand, a discharge port 14 is provided on the back surface of the cabinet 3, and the outside air flowing into the water cooler main body 1 through the outside air suction port 22 is as shown by an arrow in FIG.
After flowing through the inside of the water cooler body 1 from the front surface to the back surface, the water is discharged from the discharge port 14 to the outside. As described above, by flowing the outside air from the front surface to the back surface inside the water cooler main body 1, it is possible to sufficiently cool the compressor 4, which has not always been sufficient.

The cabinet 3 is screwed and fixed to a frame frame (not shown) of the water cooler body 1, and the front panel 9 and the drain tank 22 are also incorporated in the cabinet 3 with the frame frame as a guide.

Next, the operation will be described. When the blower 6 of the refrigeration cycle is started, the outside air is exposed to the cutout recess 2 of the drain tank 20.
1 and the bottom member 2 of the chiller body 1 flow into the chiller body 1 from an outside air inlet 22 formed. Water cooler body 1
The outside air flowing into the inside flows from the outside air suction port 22 formed on the front surface of the chiller body 1 toward the back side inside the chiller body 1, cools the compressor 4, and then passes through the condenser 5, Heat is exchanged, and then discharged from the discharge port 14 to the outside.

However, since it is not necessary to provide an outside air inlet such as a louver on the side surface of the cabinet 3, the side surface can be closely attached to the wall surface and the like, and the installation space can be reduced and the system can be reduced. It can be easily incorporated into the unit. Further, since the louvers and the like are eliminated on the side surfaces, the appearance is improved, and the compressor 4 can be cooled, so that the capacity of the refrigeration cycle can be improved.

In the embodiment described above, the drain tank 20 is provided with the cutout recess 21 and the cutout recess 21 is used to form the outside air intake port 22. However, the outside air intake port 22 is directly provided at the lower end of the front surface of the cabinet 3. May be provided.

[0017]

As described above, according to the present invention, the outside air suction port is provided in the lower part of the front surface of the chiller body, so that the side surface of the chiller body can be brought into close contact with the wall surface or the like to improve the installability. Since it can be incorporated in the system unit and the compressor can be cooled, the performance of the refrigeration cycle can be improved.

Also, by providing a cutout recess on the lower surface of the drainage tank on the main body side of the water cooler, and using this cutout recess as an outside air intake port, the outside air intake port is not exposed to the outside and the appearance can be improved.
