Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier with a cooling function incorporated into a kitchen sink or the like.

[0002]

2. Description of the Related Art Conventionally, it has been known that tap water is supplied to a water purifier and the tap water purified by the water purifier is guided to be used as purified water.

[0003]

However, in the past, only water purified by a water purifier was used in the past, so if cold water is desired, the purified water must be further cooled in a refrigerator or the like. did not become. Therefore, it is conceivable to place a cooling device in the middle of a water purification pipe that supplies tap water purified by a water purifier to cool it, but if you simply connect the cooling device to the water purification pipe, it will always cool. There is a problem in that it is difficult to use purified water that cannot be cooled because only purified water can be supplied from the lantern. Furthermore,
Since the residual water in the water purifier and cooling device flows at the first time when the carton is opened, the residual water flowing from the carton is not suitable for use, but the user does not know whether it is suitable for use. Therefore, it was used as it was, which was a sanitary problem.

The present invention was invented in view of the problems of the above-mentioned conventional examples, and the object thereof is to select and use purified water at room temperature or cooled purified water. It is to provide a water purifier with a cooling function that can drain the residual water in the cooling device to the outside through a dedicated drain pipe.

[0005]

The water purifier with a cooling function of the present invention comprises a water purifying pipe 3 for guiding the tap water supplied to the water purifier 1 to the bowl 2, and the tap water supplied to the water purifier 1. Cooling device 4
A pipe 5 for cooling water that is cooled by the water and leads to the tongue 2, and a drain pipe 6 for draining residual water in the water purifier 1 and the cooling device 4 to the outside.
And a control valve device 7 for switching and flowing tap water to any of the water purification pipe 3, the cooling water pipe 5, and the drainage pipe 6, as described above. By adopting such a structure, the problems of the conventional example described above are solved and the object of the present invention is achieved.

[0006]

The tap water purified by the water purifier 1 is caused to flow through the water purifying pipe 3 and discharged from the water purifier 2 as purified water at room temperature, or the control valve device 7 is controlled. Then, the tap water purified by the water purifier 1 is switched by the cooling device 4 and is made to flow through the cooling water pipe 5, and the cooled purified water is discharged from the tank 2 for use. on the other hand,
When it is desired to drain the residual water remaining in the water purifier 1 and the cooling device 4 when not in use, the control valve device 7 is controlled to switch the residual water in the water purifier 1 and the cooling device 4 to the outside by the drain pipe 6. It is drained to.
