Abstract

PROBLEM TO BE SOLVED: To easily indicate the temperature of water spouted from a single lever-type combination faucet when a lever of the faucet is rotated, and to make it easier to recognize the direction in which the user should rotate the lever when the temperature of the water is set to a desired temperature. SOLUTION: According to the single lever-type combination faucet, an indicating ring 26 for indicating the temperature is separately formed from a faucet main body 10 which is a fixed member with respect to the lever. Further, engaging lugs 46R and 46F are formed either on the indicating ring 26 or on an upper portion of the faucet main body 10 immediately below the lever, and engaging holes 47R and 47F are formed at the other location, i.e., in the upper portion of the faucet main body or in the indicating ring, so as to correspond to the engaging lugs 46R and 46L, respectively. In this manner, the indicating ring 26 is rigidly attached to the faucet main body 10 with the engaging lugs 46R, 46L being engaged with the engaging holes 47R and 47L, respectively.

A single-lever mixing faucet in which the amount of water is adjusted by a vertical rotation operation is widely used.

In the case of this type of conventional single-lever mixing faucet, a display unit 200 for displaying temperature is provided on the upper surface of a lever 202 as shown in an example in FIG. For a child or a short person, the display unit 200 is hard to see, and what is the current temperature, or in order to further lower or raise the water discharge temperature, rotate the lever 202 in either direction. There was a problem that it was hard to tell if it was good.

[0004] For example, the low-temperature side 200A is light blue, and the high-temperature side 2A.
00B is colored red and displayed (the same applies to other displays), the lever 20
2 is rotated to the left in the drawing, the water discharge temperature actually changes to the high temperature side. However, in the display section 200, the low temperature side 200A rotates to the left along with the lever 202 to come to the front of the user. As a result, the display is as if the water discharge temperature had changed to a lower temperature side. For this reason, there remains a problem in operability, for example, a user may be confused when operating the lever.
