The wash water in the water pressure regulating chamber 382 can be discharged into discharge chamber 388 through water pressure regulator hole 386.
    [000183] The water pressure regulating hole 386 can be formed so that the wash water can pass through the water pressure regulating hole 386 in the same direction as the wash water passes through the inlet pipe 37 6. That is, because an inlet pipe direction 376 and a wash water direction passing through the water pressure regulator hole 386 are aligned, the direction in which the wash water advances , does not need to be changed to regulate the water pressure, and the wash water can continue in the same direction.
    [000184] Furthermore, the water pressure regulating hole 386 can be arranged in a bottom part of the water pressure regulating chamber 382. The outlet of the extension tube 387 is provided to face upwards from the inside of the water pressure regulating chamber 382. The water pressure regulating hole 386 can be arranged in the bottom part of the water pressure regulating chamber 382 so that the wash water, discharged through the outlet of the extension tube 387, can be discharged through the water pressure regulating hole 386, while bypassing the interior of the water pressure regulating chamber 382, rather than being discharged directly through the water pressure regulating hole 386. However, the hole arrangement The water pressure regulator 386 is not limited in this regard, any arrangement may be used in which the water pressure regulator hole 386 is arranged in the same plane as the adjusting lug 385.
    [000185] The adjusting fin 385 and the water pressure regulating hole 386 serve as a limiting device, which performs a limiting action between the water pressure regulating chamber 382 and the discharge chamber 388. That is, the water pressure regulator hole 386 has a smaller width than an internal width of housing 372, with respect to the direction in which the wash water is flowing, so that the wash water pressure can be reduced due to friction. Pressure and a flow rate of the wash water can be regulated by the limiting action on the water pressure regulator hole 386.
    [000186] The width of the water pressure regulating hole 386 is not limited, but any width less than the cross-sectional widths of the water pressure regulating chamber 382 and the discharge chamber 388 may be possible. In the present embodiment, widths of water pressure regulating chamber 382, water pressure regulating hole 386 and discharge chamber 388 are the same, and the height of water pressure regulating hole 386 is 2 to 3 mm.

    [000189] If the water supply valve 361 is opened, the wash water is guided to the wash water supply device 370 through the auxiliary water supply pipe 362b.
    [000190] The wash water, introduced through the auxiliary water supply pipe 362b, is introduced into the water pressure regulating chamber 382, through the inlet pipe 376 and the extension pipe 387. Since the width of the space 373 of the water pressure regulating chamber 382 is greater than the width of a flow path, through which the wash water flows in the inlet tube 376 and in the extension tube 387, a flow rate can be reduced and the pressure of the wash water can be reduced while the wash water is discharged from the inlet tube 376 and the extension tube 387 to the water pressure regulating chamber 382.
    [000191] In addition, the extension tube 387 is bent upwards in the water pressure regulating chamber 382, and the pressure of the wash water can be reduced while the wash water moves upwards.
    [000192] The wash water, discharged into the water pressure regulating chamber 382 of 376 by the inlet tube and the extension tube 387, is temporarily stored in the water pressure regulating chamber 382. The stored wash water is discharged to discharge chamber 388 through water pressure regulator hole 386.
    [000193] The adjustment fin 385 is arranged between the water pressure regulating chamber 382 and the discharge chamber 388 and therefore prevents the wash water from moving from the water pressure regulating chamber 382 to the chamber discharge 388.
    [000194] Since the cross-sectional widths of the water pressure regulating chamber 382 and the discharge chamber 388, which are perpendicular to the longitudinal direction of the housing 372, are greater than the width of the water pressure regulating hole 386 , the wash water is throttled by the adjusting fin 385 and the water pressure regulator hole 386. In this procedure, the wash water pressure is reduced.
