Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite faucet in which tap water from a water supply pipe is discharged as it is or through a water purifier, and is switched to original water or purified water. Further, among them, the present invention relates to a composite mixing faucet that can selectively switch and discharge hot and cold water mixed water using raw water and hot and cold water mixed water using purified water.

[0002]

2. Description of the Related Art
Among this type of composite mixing faucet, for example, Japanese Unexamined Patent Publication No.
There was a configuration shown in Japanese Patent No. 40579.

[0003] In the composite mixing faucet disclosed in the publication, water is stopped and water is spouted by moving one operation lever up and down, and by switching the operation lever left and right in the water spouting state, original water and purified water are switched. At the same time, the mixing ratio of hot water and hot water was adjusted.

[0004] However, since switching is performed with a single operation lever, it is difficult for a user who is accustomed to a normal hot water mixer to understand the operation method, and the hot water mixed water using the original water can be discharged. However, the hot and cold water mixture using the purified water could not be discharged.

[0005] Japanese Unexamined Patent Application Publication No. 8-151668 can discharge hot and cold water using purified water, but the structure is such that hot water mixed in a mixing chamber is passed through a water purifier. For example, when hot water having a temperature of 40 ° C. or higher is passed through the water purifier, the components adsorbed on the activated carbon in the water purifier may flow out of the discharge port. Further, when hot water is passed through a water purifier, there is a problem that the synthetic resin hollow fiber membrane filter is deformed.

The one disclosed in Japanese Patent Application Laid-Open No. Hei 8-170354 is a single-lever-operated mixing valve, which switches between water stoppage and water discharge with the single lever and adjusts the mixing ratio between the original water and the hot water. Another lever for discharging purified water is used to switch between stopped and discharged water. However, for a user who is accustomed to the conventional single-lever operation type faucet, the other operation lever, which is different from the operation lever for adjusting the mixing ratio of the discharge water and the hot and cold water, is operated by operating another operation lever. Performing water stoppage is different from a familiar operation method, so there is a sense of incongruity and it is unfamiliar.

Therefore, an object of the present invention is to provide a composite water faucet for switching and discharging raw water, purified water and mixed hot and cold water as described above, which can easily switch to raw water or purified water, and to a water purifier. Hot / cold mixed water using purified water can be discharged without passing hot water.Furthermore, with the operation method that has been used for a long time, water stoppage and water discharge can be switched, and the mixing ratio of original water and hot water or pure water and hot water can be adjusted. Is to do so.
