2. Description of the Related Art In general, a single-lever type mixing faucet is superposed so that a movable plate contained in a cartridge case interposed in a valve chamber inside a main body can slide in all directions with respect to a fixed plate. Operate the lever connected to the movable plate up and down to discharge water and stop water, and rotate left and right to adjust the temperature of the mixed water, but operate the lever downward from the water stop position There is a type that discharges water by pressing the lever upward from the water stop position, and a type that discharges water by operating the lever upward from the water stop position. The two mixing faucets have opposite operation directions of water discharge and water stoppage. Therefore, for example, in the case of a mixing faucet attached to a kitchen and a mixing faucet attached to a bathroom vanity, the operation direction of spouting and stopping water may be different, which makes it difficult for a user to operate. In order to unify any of the operation directions, one of the mixing faucets had to be newly purchased and replaced, and replacement of the expensive mixing faucet was a heavy burden on the user.

[0003] In order to solve this problem, the operation direction of the lever to the water discharge and water stop position can be changed only by changing the position of some articles incorporated in the mixing faucet.

The control valve body 43 and the core member 46 are turned back and forth so as to be assembled into the housing 41, and at least one of the housing wall facing the side wall of the core member 46 and the side wall of the core member 46 has a water supply part 47 and a hot water supply part. An annular water passage 49 and an annular hot water passage 50 are respectively provided to communicate with the cooling water 48, and a water passage 51 connecting the annular water passage 49 to the water inflow hole and a hot water connecting the annular hot water passage 50 to the hot water inflow hole are provided in the core member 46. A passage 52 and a mixed water passage 53 for connecting the mixed water outflow hole to the faucet 54 are provided. From the type of FIG. 13 in which the mixed water flow rate is increased by raising the lever 45 from the water stop position,
In order to change to the type of FIG. 14 in which the flow rate of the mixed water is increased by lowering the lever 45 from the water stop position, the fixed valve seat 42, the control valve element 43, and the core member 46 may be inverted and incorporated.

[0004] The above described simply requires a fixed valve seat and a control valve body.
Just reversing will reverse the direction of temperature control left and right.
So, by inverting the core member, water discharge and water stop operation
Changing the direction does not change the operation direction of temperature control
However, this core member is attached to a normal mixing faucet.
It is not compatible with the existing mixing faucet, it is necessary to remove the existing mixing faucet and replace it with a new mixing faucet equipped with a core member, and the expensive mixing faucet is wasted. ,
Moreover, the work of rearranging many items was troublesome.
