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 in a kitchen sink or the like.

[0002]

2. Description of the Related Art It has been known that tap water is supplied to a water purifier, and the purified tap water is used as purified water.

[0003]

However, in the prior art, only water purified by a water purifier was used, so if cold water is desired, the purified water must be further cooled by a refrigerator or the like. did not become. Therefore, it is conceivable to arrange a cooling device in the middle of a water purification pipe that supplies tap water purified by a water purifier to cool it.However, simply connecting the cooling device to the water purification tube will always provide cooling. There is a problem that it is difficult to use purified water that has not been cooled because only purified water can be supplied from the beginning. Furthermore,
Since the residual water in the water purifier and cooling device flows at the first time when the noodles are opened, the residual water flowing from the noodles first 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 problem in hygiene.

The present invention has been made in view of the above-mentioned problems of the prior art, and it is an object of the present invention to selectively use purified water at normal temperature and cooled water. An object of the present invention is to provide a water purifier with a cooling function capable of draining residual water in a cooling device to the outside by a dedicated drain pipe.

[0005]

A water purifier with a cooling function according to the present invention comprises a water purifying pipe 3 for guiding the tap water supplied to the water purifier 1 to the drain 2, and a tap water supplied to the water purifier 1. Cooling device 4
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 one of the water purification pipe 3, the cooling water pipe 5, and the drain pipe 6. By adopting such a configuration, the above-described problems of the conventional example are solved and the object of the present invention has been achieved.

[0006]

The control valve device 7 is controlled and switched to flow the tap water purified by the water purifier 1 into the water purification pipe 3 and discharge it from the water 2 as normal temperature purified water, or control the control valve device 7. Then, the tap water purified by the water purifier 1 is cooled by the cooling device 4 and passed through the cooling water pipe 5, and the cooled purified water is discharged from the drain 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 through the drain pipe 6. Is to be drained.

The cooling water side outlet pipe 25 and the cooling water inlet pipe
24, water purification out pipe 26, cooling Mizuide pipe 27, the other end of the drain output pipe 28 is located on the outer surface of the water purifier casing 8, the cooling water outlet side pipe 25, the cooling water inlet pipe 24, purified water A first pipe 2 for connecting a water purifier / cooling device to each of the other ends of the outlet pipe 26, the cooling water outlet pipe 27, and the drain outlet pipe 28, respectively.
9. Each end of the second pipe 30 for water purifier / cooling device connection, the pipe 3 for water purification, the pipe 5 for cooling water, and the drain pipe 6 is connected via a connector 20. Here, the control valve device 7 is provided with three valves 7a, 7b, 7c as shown in FIG.

[0009] Heat exchange section 11 composed of pipes of cooling device 4
Are located on the outer surface of the chiller case 10, respectively, and the first pipe 2 for connecting the water purifier / cooler described above.
9. The other end of the second pipe 30 for connecting the water purifier / cooling device is connected via the connector 20. The other end of each of the water purification pipe 3 and the cooling water pipe 5 is connected to the common body 2, and the other end of the drain pipe 6 is a drain port 31. In the embodiment shown in the figure, the drain is attached to the sink 2 so that the drain water flows to the sink 33 of the sink 1.

An operation section 32 is provided on the karaoke machine 2. By operating the operation section 32, the control valve device 7 is controlled by a control section 9 comprising a microcomputer, and the valve 7a is opened and closed to introduce tap water. After switching the pipe 18 between tap water and non-pass water, or by switching the valves 7b and 7c, the tap water flowing through the tap water inlet pipe 18 flows into the water purifier 1 and is purified, and then the purified water is derived. The water flows from the pipe 23 through the control valve device 7 to the water purification pipe 3 from the water purification pipe 26, and is discharged from the pipe 2 as purified water at normal temperature, or the tap water flowing through the tap water introduction pipe 18 is used as a water purifier. after being purified flows to 1, exit the cooling water side through the control valve unit 7 from purified water outlet pipe 23 pipe 2
