Although the cover 80 is provided so as to cover substantially the entirety of the hot and cold water mixing tap 1, it is also possible to cover only high temperature parts such as the front and top surfaces to prevent burns.

Since the second embodiment is constructed as described above, the external appearance can be improved without exposing the hot water side socket 40, the water side socket 50 and the faucet main body 10. In addition, since high-temperature portions such as the hot-water socket 40 and the hot-water connection port 11 that are communicated with the hot-water supply pipe are covered with the cover 80, the high-temperature portion of the hot-water mixer tap 1 has a user's hand or the like. Can be prevented from touching and causing a burn or the like. Further, since the amount of projection of the sockets 40 and 50 toward the front side of the faucet main body 10 is small, the cover 80 can be made compact as a whole.

[0020]

As described above, in the hot and cold water mixing tap according to the first aspect, the water faucet main body from the position of the mounting hole on the deck surface is different from the water faucet main body in which the connection port is provided on the back side of the water faucet main body. Can be reduced in the forward projecting amount. Therefore, when the hot and cold water mixing tap is used, the faucet main body and the water discharge pipe are less likely to protrude to the sink of the sink, so that there is no problem of obstruction. Further, since the amount of protrusion of the faucet body and the water discharge pipe to the front can be reduced, the stress applied to the connection port, the hot water side socket, and the water side socket due to impact applied to the water faucet body and the water discharge pipe is reduced. This can reduce the bending and damage of the socket and the connection port. Furthermore, since the stopcock or strainer is provided on the socket bent in a crank shape, it is not necessary to provide these on the faucet body, and the faucet body can be easily miniaturized. Since a water stopcock or strainer is arranged between the main bodies, these can be easily operated. Claim 2
In the hot and cold water mixing tap, the external appearance can be improved without exposing the socket and the water tap main body. In addition, since hot parts such as the hot water side socket and the hot water side connection port that are communicated with the hot water supply pipe are covered with the cover, the user's hand skin touches the high temperature part of the hot water mixer tap and burns. Etc. can be prevented. Furthermore, since the amount of projection of the socket toward the front side of the faucet main body is small, the cover can be made compact as a whole.
