Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to a water cooler in which a water supply pipe is connected to a water supply.

(Prior Art) In this type of water cooler directly connected to the water supply, for example, a water cooler with an automatic cleaning function, as shown in FIG. A drain pipe 5, one end of which is connected to the bottom surface of the cooling tank 4, is connected to a drain pipe 3 connecting the drain port 2 provided on the side surface of the box-shaped outer body, and an on-off valve 6 provided on the drain pipe 5 is opened. The cooling water in the cooling tank 4 is drained from the drain port 2 to the drain pipe 7 via the drain tube 3, and the inside of the cooling tank 7 is cleaned.

(Problem that the invention aims to solve) However, in the above-mentioned type of water cooler that is directly connected to the water supply, the open end of the drain pipe is located in the flow path of the drain pipe, so the waste water flowing inside the drain pipe is It is unsanitary, and there is also the risk that bacteria may enter the cooling tank due to the dirty water flowing through the drain pipe.

Therefore, the present invention has been made in view of the above points, and an object of the present invention is to provide a water cooler that prevents sewage from splashing on the drain pipe and eliminates contamination caused by overflowing sewage caused by clogged drain pipes. purpose.

[Structure of the idea]

(Means for Solving Problems) The water cooler of the present invention has an outer body provided with a saucer and a drain port, a cooling tank having a water outlet provided inside the outer body, a drain hole in the saucer and the outer body. In a water cooler having a drain pipe connected to a drain port, an overflow part is provided in a part of the drain pipe near the drain port, and one end of the drain pipe is connected to the water drain port, and the other end is placed directly above the overflow part. It is arranged inside the outer body so that it is placed and located.

(Function) In the water cooler of the present invention, the open end of the drain pipe connected to the water outlet of the cooling tank is located directly above the overflowing part provided in the drain pipe, and there is a gap between the open end and the overflowing part. Since the drainage pipe does not come into direct contact with the sewage flowing through the drain pipe, the drainage pipe will not be contaminated with sewage, and even if the drain pipe becomes clogged, no pollution will occur due to overflowing sewage.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 10 denotes a box-shaped outer body, and a receiving tray 11 is formed on the upper surface of this outer body 10. As shown in FIG. In one corner of this saucer 11, there is a spout 12 for spouting cold water;
Drain holes 13 for discharging cold water are formed in corners diagonally opposite to the corners provided with 2. A drain port 14 and a water supply port 15 are provided on the side surface of the outer body 10, and the drain port 14 has a drain pipe 16 connected to a drainage channel, and the water supply port 15 has a water supply port 16 connected to a water pipe. A tube 17 is connected to each.

On the other hand, inside and above the outer body 10, a drain pipe 18 is provided.
A cooling tank 19 and a cooling device 20 are provided in the lower part of the interior.

The drain pipe 18 has one end connected to the drain hole 13 provided in the receiving tray 11, and the other end connected to the outer body 10.
An overflow portion 22 is connected to a drain port 14 provided in the drain port 14, and an overflow portion 22 with an upward opening is formed in a portion close to the drain port 14 via a partition wall 21.

The cooling tank 19 has a water outlet pipe 23 on the top surface.
One end and one end of the water supply pipe 24 are connected to each other, and the other end of the water outlet pipe 23 is connected to the receiving tray 1.
The other end of the water supply pipe 24 is connected to the water supply port 15 via an on-off valve 25. Further, a cooling pipe 26 of a cooling device 20 is wound around the outer peripheral surface of the cooling tank 19.
The cooling tank 1 is cooled by the refrigerant passing through the cooling pipe 26.
The water stored in the tank 9 is cooled.

On the other hand, a water outlet 27 is provided on the lower surface of the cooling tank 19.
The drain pipe 28 has one end connected to the drain port 27, and the other end of the drain pipe 28 extends directly above the overflowing portion 22 of the drain pipe 18 via an on-off valve 29.

That is, as shown in FIG. 2, the open end of the drain pipe 28 is located directly above the opening of the overflowing part 22 of the drain pipe 18 and a distance a above the end surface of the overflowing part 22, so that the drain pipe 28 does not allow the sewage to reach Avoid direct contact.

Furthermore, a water supply switch 31 operated by a water supply pedal 30 is attached to the on-off valve 25 provided on the water supply pipe 24, and a water drain switch 32 is attached to the on-off valve 29 provided on the water drain pipe 28.

Reference numeral 33 in FIG. 1 is a timer device which opens the on-off valves 25 and 29 for a predetermined period of time, forcing the tap water to circulate within the water circuit and cleaning the inside of the cooling tank.

Next, the action will be explained.

When the user depresses the water supply pedal 30 under the condition that the cooling device 20 is operated and the water in the cooling tank 19 is cooled by the cooling pipe 26,
The water supply switch 31 is turned on, the water supply on-off valve 25 is opened, and tap water is supplied into the cooling tank 19 through the water supply pipe 24.

When tap water is supplied into the cooling tank 19, the cold water in the cooling tank 19 is pushed up, passes through the water outlet pipe 23, and is discharged from the spout 12.

The water spilled by the user is sent into a drain pipe 18 from a drain hole 13 provided in a saucer 11, and is discharged to the outside through a drain port 14 and a drain pipe 16.

If you regularly clean the water circuit of your water cooler,
By activating the timer device 33 with preset conditions, the water drain on-off valve 29 provided on the water drain pipe 28 and the water supply on-off valve 25 provided on the water supply pipe 24 are opened, and tap water is forced into the water circuit. Have them circulate.

The cold water in the cooling tank 19 due to the circulating tap water passes through the drain pipe 28 and falls toward the overflow part 22 from just above the overflow part 22 of the drain pipe 18. Since the open end of the drain pipe 28 is located at a distance a from the overflow part 22, even when the drain pipe 16 is clogged and sewage overflows, the sewage does not enter the drain pipe.

[Effect of idea]

As described above, according to the present invention, waste water such as waste water does not splash into the drain pipe, making it sanitary, and even if the drain pipe is clogged and sewage overflows, the sewage does not enter the drain pipe. Moreover, the structure is simpler than the conventional one.
