2. Description of the Related Art In recent years, a faucet attached to a sink or a ball installed in a kitchen or a restroom, etc.
Water, hot water or a mixture of hot and cold water that can selectively discharge water is increasing. On the other hand, treated water, such as drinking water, is connected to a water purifier or a cooler faucet to an auxiliary water pipe branched from a water supply pipe connected to the faucet of the sink or bowl, and is located away from the sink or bowl. In most cases, a water purifier or cooler is installed and water is discharged from a faucet dedicated to treated water.

[0003] In these conventional facilities, it is necessary to separately pipe the water supply pipe and an auxiliary water supply pipe branched from the water supply pipe, so that not only the work is complicated but also the piping construction cost is increased. There is. A proposal for resolving such inconvenience is disclosed in, for example, Japanese Utility Model Laid-Open No. 63-66676. According to this proposal, a water supply channel formed in the main body of water, hot water or a hot and cold water mixing faucet is to be shared with a water supply channel for treated water. That is, a part of a water supply passage formed in the water faucet body and connected to a water supply source such as a water pipe is branched in the water faucet body and opened to the side of the water main body, and the opening is purified through a pipe. The faucet and the water purifier are connected to a water heater or a cooler so that water can be supplied to the faucet body and the water purifier simultaneously or separately, and water, hot water or a mixture of hot and cold water and purified water can be simultaneously or separately discharged from each faucet.

[0004] For example, Japanese Utility Model Laid-Open Publication No. 2-121873 discloses a hot water mixer tap body provided with two inflow ports for water and hot water, and a mixed water outflow port for discharging mixed water of hot water and water. An outlet port for a water purifier, a flow path formed in the mixer tap body, a mixed water system flow path connecting the two inflow ports and the mixed water outflow port, only the inflow port for water, and an outflow port for the water purifier. A hot water mixer tap is disclosed, which can be divided into a water purifier system flow path connecting a port and a switching means for selectively switching between the mixed water system flow path and the water purifier system flow path. As the switching means, a fixed disk having four flow paths communicating with the respective ports and a movable disk having two long holes rotatable and rotatable with the fixed disk are employed. By combining the passage and the long hole, water, hot water, mixed water or purified water can be selectively discharged from one faucet.

Water faucets such as water purifiers are provided independently at a certain distance, and when using the water faucet body and the water purifier at the same time, two water faucets separated by a certain distance Must be operated, which is complicated when used simultaneously. Further, since the water purifier and the like are naturally installed alone in a state of being exposed to the outside, not only an independent plane space is required for that, but also a pipe connecting the water faucet body and the water purifier and the like is provided outside. There is also a problem with the appearance, coupled with the appearance.

On the other hand, the equipment disclosed in Japanese Utility Model Laid-Open Publication No. 2-121873 is effective in that a faucet for a sink or a ball and a faucet such as a water purifier can be shared, and the water purifier and the like can be stored in the sink. However, it is impossible to use water, hot water or hot and cold water and purified water at the same time. Further, the most inconvenient point of the mixing tap disclosed in the publication is that a part of the flow path of water, hot water and mixed hot and cold water is shared with the flow path of purified water.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a water faucet for ordinary water, hot water or a mixture of hot and cold water and a water faucet such as a water purifier are integrated to save space. Combined water in which all operations can be performed at hand, and furthermore, the outflow paths of water, hot water or mixed hot and cold water and treated water are completely independent so that they can be used simultaneously or separately. It is intended to provide a stopper.

[0009]

In order to achieve the above object, the present invention provides a water faucet body in which a hot water supply path connected to a hot water supply pipe, a water supply path connected to a water supply pipe, and an outflow path leading to a water discharge pipe are independently formed.

A treatment water passage communicating with the water discharge pipe via a check valve and a water treatment device to the water supply passage, and operating means for the check valve, wherein the water discharge pipe is rotatably provided with water.
It is provided on the plug body and is divided into one for the outflow channel and one for the treated water.
Is to be a main constituting comprising further a specific embodiment, the water discharge pipe is water, hot water, is divided into a outflow passage of hot and cold water mixing water and for processing waterway and said outlet to said faucet body The water discharge pipe for the channel and the water discharge pipe for the treated water channel are independent of each other.
In some cases , both water discharge pipes can be freely contacted and separated.

[0010]

When the switching means of the composite faucet is operated alone, the flow path of water, hot water, or mixed hot and cold water in the faucet main body can be arbitrarily switched, and the water amount and the water temperature can be adjusted selectively from the water discharge pipe while adjusting the amount and temperature of the water. Discharge. On the other hand, when the check valve operating means for treated water provided in the composite faucet is operated alone, the switching means is at the water stop position, and only treated water such as purified water is discharged from the water discharge pipe. When the switching means and the check valve operating means are operated at the same time, any of water, hot water and mixed water and treated water are simultaneously discharged from the water discharge pipe. Now, when the water discharge pipe for water, hot water and mixed water and the water discharge pipe for treated water are provided independently and rotatably , the water, hot water or mixed water and water can be treated at any rotational position. Water is discharged from each water discharge pipe.

Further, in the case where the two water discharge pipes are provided so as to be able to come and go, water, hot water or mixed water and treated water can be used simultaneously and individually.
