Description of the Related Art Generally, a single-lever type mixed faucet is constructed by stacking a movable plate inside a cartridge case interposed in a valve chamber inside a main body so that it can slide in any direction with respect to a fixed plate. By operating the lever handle linked to the movable plate up and down, water is stopped and water is stopped.
The temperature of the mixed water is adjusted by rotating it to the left and right, but the type that discharges water by operating the lever handle downward from the water stop position, and the type that discharges water by operating it upwards There are two types of water faucet, and the operation directions of the two mixed faucets are opposite. Therefore, for example, a mixed faucet attached to the kitchen and a mixed faucet attached to the vanity may have different operating directions for water discharge and water stoppage.
It is difficult for the user to operate, but in order to unify the operating direction of both mixed faucets, one of the mixed faucets must be newly purchased and replaced, and expensive expensive mixed faucet replacement is required. It was a heavy burden on the person.

Therefore, as shown in FIGS. 5 to 10, it is possible to change the water discharge of the lever handle and the operation direction to the water stop position only by exchanging some of the articles incorporated in the mixing faucet. is there. Briefly explaining with reference to FIGS. 5 to 10, the mixing faucet 1 includes a fixed plate 2 having a water supply hole 3, a hot water supply hole 4 and a discharge hole 5, and a mixing chamber 7 opened to the fixed plate 2 side. A first plate valve unit 9 in which a movable plate 6 formed inside is slidably faced is detachably mounted inside a separately provided cartridge case 10, and the cartridge case 10 is interposed in a valve chamber 12 of a main body 11. . A guide 14 is fitted and arranged from above into the mixing chamber 7 of the movable plate 6 via a packing 13, and a lower end of a handle shaft 16 is fitted into a recess 15 formed in the upper end surface of the guide 14, Handle axis 1
The upper portion 16 a of the lever 6 is fitted into the cylindrical inclined hole 18 recessed from the lower portion of the lever handle 17 and is joined by the screw 19. Therefore, when the lever handle 17 connected to the movable plate 6 is operated in the up-down direction to adjust the water discharge amount and pivoted in the left-right direction, the temperature can be adjusted, and when the lever handle 17 is in the position shown in FIG. As for the positional relationship between the fixed plate 2 and the movable plate 6, the water supply hole 3 and the hot water supply hole 4 of the fixed plate 2 are closed by the sliding contact surface 8 of the movable plate 6 as shown in FIG. When the operating portion 17a of the lever handle 17 is operated downward from the state, the movable plate 6 is moved as shown in FIG.
Moves, and the water supply hole 3 and the hot water supply hole 4 of the fixed plate 2 move to the movable plate 6

As for the positional relationship between the movable plate 6a and the movable plate 6a, the movable plate 6a moves as shown in FIGS. 9 to 10, and the water supply hole 3a and the hot water supply hole 4a of the fixed plate 2a communicate with the mixing chamber 7a of the movable plate 6a to form the discharge hole. Water discharge from the water discharge pipe 20 is started via 5a.

Among the above-mentioned ones, the type that discharges water by operating the lever handle downward and the type that discharges water by operating upward are stopped as shown in FIGS. 5 and 8. Since the position of the plate valve unit in the cartridge case in the water state moves back and forth, the inclination angle of the lever handle connected to the plate valve unit also differs. Normally, a single lever type mixed faucet moves the lever handle up and down for water discharge and water stop, but when the water is stopped, the balance between the main body and the lever handle is the best and the tilt angle of the lever handle is set so that it is easy to operate. However, the inclination angle of the lever handle in the water-stopped state is different between the case of lowering water discharge and the case of raising water discharge, and the balance between the main body and the lever handle is unbalanced in either state, which is a design Since it becomes unsightly and causes problems in terms of operability, it is necessary to fabricate and prepare two lever handles, one for the type that lowers and discharges water and the other for the type that raises and discharges water. was there.
