Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a water treatment device such as a filter water purifier that also serves as hot and cold water, and the amount of water, the amount of hot water and the mixing ratio thereof can be freely switched, and the normal operation can be performed by operating two handles. The present invention relates to a multifunctional composite faucet capable of switching between hot water, water, or mixed hot and cold water, and hot and cold water of a water treatment device such as a hot and cold water filter.

[0002]

2. Description of the Related Art Heretofore, there has been proposed a faucet which is provided with a water treatment device such as a water purifier and which can control the discharge of normal water, hot water, hot water mixture and purified water by operating a handle. For example, the faucet described in Japanese Utility Model Laid-Open No. 4-117270 is a water faucet body having a discharge port, an operation handle that is tiltably and rotatably supported on the faucet body at an upper portion, and a water treatment device such as a water purifier. A fixed disk provided with a device, having a clean water inlet, a raw water inlet, and a hot water inlet in the faucet body, and slidably slidably contacting the fixed disk, and sliding by a tilting operation of an operating handle to introduce a clean water inlet. Or a movable disk for connecting the raw water inlet and / or the hot water inlet to the outlet, and further connecting the raw water inlet and the outlet of the water treatment device, respectively. Is. The faucet described in Japanese Utility Model Laid-Open No. 4-117270 has a normal water, which is produced by tilting and rotating the operation lever.
It is possible to control hot water or hot and cold water mixture and discharge of purified water.

On the other hand, conventionally, a water purifier has only a function of treating only normal water and cannot treat hot water at a high temperature. However, in recent years, there has been a demand for the development of a hot water filtration water purifier capable of treating hot water, and for that reason, research and development of a filter material having excellent heat resistance and an adsorbent for high temperatures have been promoted.

[0004]

However, the above-mentioned conventional composite faucet is of a type that sends only water to the water purifier and discharges the treated water. When attached, hot water could not be passed through the water purifier, and it was impossible to supply the treated hot water using the water purifier that also serves as hot water.

The present invention has been made in view of the above circumstances, and a filter water purifier for combined use of hot and cold water can be attached, and the water amount, the hot water amount, and the mixing ratio thereof can be freely switched, and a normal operation can be performed each time by operating two handles. It is an object of the present invention to provide a multifunctional composite faucet capable of switching between hot water, water, or mixed hot and cold water and treated hot and cold water treated with a hot and cold combined use water purifier.

And a second switching unit having a second movable disk that communicates with the hot water outlet. In addition, a first hot and cold water discharge passage that leads to the hot and cold water discharge passage to the second hot and cold water outlet, and a second hot water and water outlet that passes from the third hot and cold water outlet and passes through the water treatment device and is returned to the faucet body. It may be divided into a hot water discharge passage.

[0007]

In the multi-function composite faucet of the present invention, the first operating handle is operated to cause the first movable disk of the first switching portion to slide on one surface of the first fixed disk, and the hot water inlet and the water inlet. By connecting one or both of the inlets to the first hot water outlet,
Either hot water, water, or hot water mixed water is discharged from the first hot water outlet. On the other hand, the second operation handle is operated to cause the second movable disc of the second switching portion to slide on one surface of the second fixed disc, so that the hot and cold water inlet can be either the second hot water outlet or the third hot water outlet. By connecting the water to the crab, hot water, water, or hot-water mixed water introduced from the hot-water inlet can be directly discharged from the discharge port through the hot-water discharge passage or sent to the water treatment device to discharge the treated water. Therefore, the multi-function composite faucet of the present invention can be operated by using two handles,
Discharge / stop of hot water, hot and cold water mixed water, treated water, treated hot water and hot and cold water mixed treated water, and adjustment of discharge amount and temperature can be performed. Further, the hot water discharge passage is divided into a first hot water discharge passage communicating with the first hot water discharge outlet and a second hot water discharge passage leading to the second hot water discharge outlet, Ordinary hot water, water, or hot and cold mixed water and treated hot water, treated water, or hot and cold mixed treated water can be discharged through different routes.
