[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand-washing spout provided on a flush water tank integrated with a toilet.

[0002]

2. Description of the Related Art In a case where a flush water tank is provided in a toilet body, flush water is sent from the flush water tank to a bowl of the toilet body to drain sewage, and a hand-washing device is provided to wash hands. I do. This water spout is generally provided with a hand-washing bowl on a lid of a washing water tank and spouting water. The water spout pipe of the water spout penetrates the lid and is fixed up. Then, the base end of the water discharge pipe is connected to a ball tap of the wash water tank, and after draining operation, a part of the wash water is supplied to the water discharge pipe to discharge water into the hand-washing basin while the water is stored in the wash water tank. ing.

[0003] In the washing water tank provided with such a water discharging device, the discharge condition of water from the water discharging pipe also changes depending on the flow rate of water to the cleaning water tank. That is, if the supply flow rate is large, the time for storing water in the washing water tank is shortened, and the momentum of water from the water discharge pipe is strong. Conversely, when the flow rate is small, the flow rate of water from the water discharge pipe is also reduced, and the momentum is weakened. For this reason,
If the flow rate is too high, the water from the wash basin will be violently splashed, and if the flow rate is too low, sufficient hand washing may not be performed.

On the other hand, in order to adjust the flow rate, for example, a facility is used in which a water stopcock is incorporated in a supply pipe to a ball tap of a washing water tank and the valve opening is adjusted. In addition, since such a stopcock is often located in a narrow space between the washing tank and the wall and is inconvenient to handle frequently, a flow control valve is incorporated at the base end of the water discharge pipe. There are also things.

In this flow control valve, a cylindrical valve element is rotatably incorporated into a flow path, and the valve element is rotated by a driver or the like to adjust the degree of matching between a hole formed in the valve element and the flow path of the water discharge pipe. Is to adjust the flow rate.

[0006]

However, since the conventional water discharge pipe rises with its base end penetrating through the lid, if a valve for adjusting the flow rate is provided at the base end of the water discharge pipe, it will be difficult to use a tool. The face is turned forward and exposed. For this reason, not only is the appearance unfavorable, but also dust and the like are liable to be clogged in the uneven portions on the surface, and there is a problem in hygiene.

As a simple structure, a snap ring is used as a member for restraining the valve body on the water discharge pipe side. This snap ring is a split ring in which a steel wire is formed into an arc shape, and is fitted to a built-in portion of a valve body by using its elastic force to restrain and hold an end face of the valve body.

However, assembling such a snap ring is troublesome, and if the snap ring is not fitted tightly, it may hinder the rotation of the valve body or the valve body may come off.

The problem to be solved in the present invention is to make it possible to easily incorporate a valve body for adjusting a flow rate into a water discharge pipe for hand washing with good appearance.

[0010]

According to the present invention, a hand basin is provided at an upper end of a washing water tank provided in a toilet body, and a water supply system branched from a water supply path to the washing water tank is provided toward the hand basin. A hand-washing spout provided with a spout for spouting water in the hand-washing bowl, wherein a guard is set up in the hand-washing pot, and the spout is protruded forward from the front of the guard and fixed, and the spout is , A holding seat opened on the lower surface,
A valve body inserted from the holding seat and capable of restricting an internal flow path toward a water discharge end; and a restraint engaged with an outer periphery of a lower end of the holding seat and detachably attached to restrain a substantially lower surface of the valve body. And a member.

[0011]

Since the water discharge pipe protrudes forward from the guard raised on the back side of the hand-washing bowl and is fixed, the lower end portion of the holding seat into which the valve body for flow rate adjustment is inserted is oriented downward. For this reason, the holding seat and the lower surface of the valve element inserted therein have an assembled structure that is not exposed when viewed from the front. Also,
Since the restricting member that restricts the valve body engages with the lower end of the holding seat, the attaching and detaching operation is easier than when a snap ring is fitted on the inner periphery.

I have. Reference numeral 4d denotes a float for operating the valve mechanism of the ball tap 4a according to the level of the washing water.

The upper end of the casing 2 and the
A guard 6 which rises upward is formed on the back, and the inside of the guard 6 is hollow, and this is used as a piping chamber 6a. A connection pipe 7 connecting the supply pipe 4c from the cleaning water tank 4 and the water discharge pipe 5 is housed and fixed in the pipe chamber 6a. A joint 7a for connecting the water discharge pipe 5 is integrally formed at the upper end of the connection pipe 7, and the joint 7a faces the mounting hole 6b of the water discharge pipe 5 opened in the guard 6.

On the other hand, the water discharge pipe 5 has a water discharge head 5a opened at the lower surface of the distal end thereof, and a synthetic resin joiner 8 for connecting to the joint 7a of the connection pipe 7 is integrally fixed at the base end. I have. The joiner 8 forms a flow path from the connection pipe 7 to the water discharge head 5a by fitting the joint portion 7a in a watertight manner. A cylindrical holding seat 9 protrudes downward from the lower surface on the base end side of the water discharge pipe 5 to open a lower end thereof, and a flow rate adjusting mechanism which also serves as a drainage mechanism for preventing freezing by using the holding seat 9. Is incorporated. FIG. 4 is a longitudinal sectional view of a flow rate adjusting mechanism, and FIG.
6 and FIG. 6 are cross-sectional views taken along lines AA and BB in FIG.

The flow rate adjusting mechanism includes a support member 10 communicatively connected to an internal flow path of the joiner 8, a valve body 11 for flow rate adjustment rotatably inserted from the holding seat 9 into the support member 10, and the valve body. The cap 11 serves as a restraining member for restraining the holding member 11 in the holding seat 9.

FIG. 7 (a) is a partially cutaway side view of the water discharge pipe 5, and FIG. 7 (b) is a sectional view taken along line CC of FIG. At the outer periphery of the lower end of the cylindrical holding seat 9 protruding from the lower surface of the water discharge pipe, a receiving seat 9a having a small diameter for fitting the cap 12 is provided ((c) in FIG. 7). Has an engaging claw 9b extending below the receiving seat 9a.
Is formed. These engaging claws 9b are provided with protrusions 9c bulging outward as shown in FIG. In the example of FIG. 7, the engaging claws 9b are formed on the right and left when viewed from the front, but in FIGS. 1, 4 and 5, these engaging claws 9b are provided at two places in the front-rear direction. As shown.

8A and 8B show details of the support member 10, wherein FIG. 8A is a partially cutaway plan view and FIG. 8B and FIG. 4) is a vertical sectional view taken along the line DD and a line EE. Supporting tool 1
Numeral 0 is provided with a connecting cylinder 10a at one end thereof for communicating and connecting to the joiner 8, and forming a chamber 10b for receiving a valve element having a circular cross section in connection with this. The chamber 10b has its lower end opened, and has an inflow hole 10c which opens to the joining cylinder 10a side and an outflow hole 10d which is provided coaxially with the inflow hole 10d at a position facing the radial direction, on the peripheral wall. . In addition, as shown in FIG. 4, this support 10 is incorporated so as to be located coaxially with the opening of the holding seat 9.

9A and 9B show the details of the cap 12. FIG. 9A is a plan view, FIG. 9B is a right side view, and FIGS. 9C and 9D are FIGS. FIG. 3 is a vertical sectional view taken along arrows FF and GG of FIG. The cap 12 includes a peripheral wall 12a having an inner diameter that can be fitted to the receiving seat 9a of the holding seat 9,
An operation hole 12b is opened therein. In the peripheral wall 12a, two engagement holes 12c into which the projections 9c of the engagement claws 9b provided on the holding seat 9 are fitted are opened. The opening edge of the operation hole 12b is provided with two stoppers 12d for the valve body 11 which is raised in the axial direction.

Further, as shown in FIGS. 4 to 6, the valve body 11 is formed in a bottomed cylindrical body having an outer diameter that fits tightly into the chamber 10b of the support 10. Openings 11 a and 11 b having the same axis in the radial direction are opened at two places on the peripheral wall of the valve body 11, and a packing 11 c for sealing between the opening 11 a and the inner wall of the holding seat 9 is attached. A groove 11d for tooling is formed in the bottom surface of the valve body 1.

The flow rate adjusting mechanism R is incorporated into the water discharge pipe 5 in the following manner. First, the supporter 10 integrated with the joiner 8 is prepared, and these are inserted from the back of the water discharge pipe 5 to fix the joiner 8 to the water discharge pipe 5. At this time, it goes without saying that the support 10 is assembled so that the chamber 10b is coaxial with the opening center of the holding seat 9. Next, valve element 1
1 from the holding seat 9 and the upper end thereof is
Insert until it hits the top wall inside. By this insertion, the packing 11c is fitted to the inner peripheral wall of the holding seat 9, and is maintained at the position shown in FIG. 4 unless a strong external force is applied.

After the valve body 11 is assembled, the cap 12 is attached to the holding seat 9 to prevent the valve body 11 from coming off. This is because the engaging hole 12c of the cap 12 is
The cap 12 may be pushed up from below by adjusting it to the position b. At this time, the engaging claw 9b is elastically deformed inward and receives the approach of the cap 12 to the receiving seat 9a side, and when the projection 9c is fitted into the engaging hole 12c, the engaging claw 9b is restored to its original state. Therefore, as shown in FIG. 4, the projection 9c of the engagement claw 9b is engaged with the engagement hole 12c, and the cap 12 is
Integrated into Then, as shown in FIG.
2 is fixed, the upper end of the stopper 12d and the valve body 11
A small gap 13 is formed between the bottom surface of the valve body 11 and the bottom surface of the valve body 11 and no restraining force acts on the lower surface of the valve body 11.

In the above configuration, after the valve body 11 of the flow rate adjusting mechanism is assembled, if the projection 9c of the holding seat 9 is fitted into the engagement hole 12c of the cap 12, the cap can be one-touch type. 12 can be fixed to the water discharge pipe 5. For this reason, the cap 12 can be easily attached and detached as compared with a conventional case using a snap ring or the like.
Even if the valve body 11 is lowered, the stopper 12d of the cap 12 restrains the lower surface on the outer peripheral side of the valve body 11, so that the valve body 11 does not fall off.

The valve element 11 has a groove 11d for tooling.
If you insert a screwdriver or coin into the inside and turn it,
The degree of matching between 1a, 11b and the inflow hole 10c and outflow hole 10d of the chamber 10b can be changed. That is, in the case of FIG. 6, the openings 11a and 11b and the inflow hole 10
c, the outflow holes 10d are aligned coaxially, and at this time, the flow paths are perfectly aligned and the throttle is zero. When the valve body 11 is turned clockwise or counterclockwise, the openings 11a,
Since the position of 11b also changes, the degree of matching between the inflow hole 10c and the outflow hole 10d decreases. Therefore, the flow path from the joiner 8 to the water discharge head 5a is gradually narrowed, and the flow rate of water from the water discharge head 5a is also reduced. In addition, at the time of this rotation operation of the valve body 11, since the stopper 12d does not abut against the lower surface of the valve body 11,
The flow rate can be adjusted by slightly turning the valve body 11.

Further, since the holding seat 9 is provided below the base end of the water discharge pipe 5, the operation hole 12b of the cap 12 and the lower end of the valve body 11 are not visible even from the front. For this reason, the appearance is improved as compared with the conventional case where the valve body for flow adjustment is exposed on the front side.

The valve element 11 of the flow rate adjusting mechanism R can be used for draining water to prevent freezing. This draining is performed by opening a hole in the lowest level portion of the supply pipe 4c running on the washing water tank 4, opening the water discharge pipe 5 to the atmosphere by extracting the valve body 11, and opening the connection pipe 7. It drains the water that has accumulated up to the top.

Further, a groove may be formed on the inner periphery of the lower end of the holding seat 9, and the cap 12 may be engaged with the groove so that the lower surface of the valve body 11 can be restrained.

[0029]

[Effects of the Invention] In the present invention, the water discharge pipe is made to protrude forward from the front surface of the guard, and the holding seat is provided on the lower surface thereof, so that the valve body incorporated in the lower surface of the holding seat or inside thereof is exposed to the front side. do not become. For this reason, the external appearance is improved and dust and the like are less likely to be attached, so that it can be used sanitarily. Further, since the restraining member for preventing the valve body from coming off engages with the outer periphery of the holding seat, the attachment and detachment can be performed more easily than when a snap ring or the like is incorporated in the holding seat for restraining the valve body.
