[0014]
In the above configuration, hand wash water enters the annular groove forming portion 15 through the drain pipe standing from the lid plate 7 simultaneously with the drainage of the liquid in the water storage tank, and resists the elasticity of the elastic leg pieces 17 as the weight increases. As shown by 2, the annular groove forming portion descends and the lower end of the leg portion 18 is in contact with the first bottom plate 3. The water that has entered the annular groove forming portion 15 passes through the second drain hole 19 and also flows through the gap between the first cylinder portion 4 and the second cylinder portion 24, and then passes through the first drain hole 6 to form a water storage tank. Enter inside. Since the chemical solution storage cylinder 21 has the inward flange 23 placed on the seat 16 of the annular water filling member 11, when the annular groove forming portion 15 of the annular water filling member is lowered, the poppet as shown in FIG. The valve 30 stops at the lower end of the valve shaft 29 in contact with the second bottom plate 5, whereas the chemical storage cylinder 21 descends together with the annular groove forming portion having the receiving seat 16, so that the valve head 28 is separated from the valve seat 27. Then, the discharge valve 26 is opened, and then the chemical solution flows down the valve seat 27 through the narrow groove 31 and mixes with the water in the lower portion of the first cylindrical portion 4, both from the first drain hole 6 into the water storage tank. It will flow down.
[0015]
The annular water filling member 11 rises due to the elastic restoration of the elastic leg piece 17 as the water in the annular groove forming portion 15 decreases and becomes lighter, and then the chemical solution storage cylinder 21 is also lifted together. When the three cylinder portions 25 are raised, the valve seat 27 comes into contact with the valve head 28 to raise the poppet valve 30 and close the discharge valve 26.
[0016]
【The invention's effect】
In the present invention, the base member 1 opens the central portion of the first bottom plate 3 and hangs down the first cylindrical portion 4, so that the first cylindrical portion is the through hole of the water storage tank cover plate 7.
