DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In order to finish fixing the hand washing bowl 53, the water discharge pipe 5
4 and the connection pipe 56 and the connection between the connection pipe 56 and the bellows pipe 55 by the cap nut 55 are required.
That is, since the water discharge pipe 54 is a connection system in which the water discharge pipe 54 is simply inserted into the attachment position of the hand washing bowl 53, the connection must be made at such two places, and the work is complicated.

Further, as shown in (a) of the same figure, since the cap nut 57 is located slightly inside the rising wall 53a, the work of hanging a tool and rotating it is considerably troublesome and troublesome. It takes. And the fastening of the cap nut 57
Due to such poor workability and the inability to confirm the fastening condition visually, if water is not assembled sufficiently, water will leak from this connection part. For this reason, water falls on the inner lid 51a that covers the upper end of the wash water tank 51, and this flows down along the peripheral wall of the wash water tank 51, which adversely affects the functional parts built into the casing 50.

Further, the connecting pipe 56 inserted into the rising wall 53a is provided with a rib-shaped fixed seat 56a at its upper end so that it can be stably held in the rising wall 53a.
However, since the base end of the water discharge pipe 54 is directly connected to the connection pipe 56, the fixed seat 56a is provided when an external force acts on the water discharge pipe 54, for example, when the handwash bowl 53 is made of synthetic resin or the like. Mouth water pipe 54
There is a surface that is insufficient for fixing the.

As described above, in the conventional structure in which the hand-washing pot is provided at the upper end of the casing and the water discharge pipe of the hand-washing pot is connected to the pipe from the wash water tank in the casing, not only is the piping work complicated, but also water leakage and spouting There is a risk of rattling of the water pipe.

An object to be solved in the present invention is to easily connect a water outlet provided in a handwash bowl and a flow path from the low tank side, and to prevent leakage of water and reduction in assembly strength of a water discharge pipe.

A hand-washing pot having a spout connected to the other end of the water supply passage and attached with the front of the rising wall facing forward, wherein at least one end of the water supply passage is inserted into the rising wall through the rising wall. The water supply passage insertion portion is provided.

In such a structure, the water supply passage may be formed of a flexible tube, and the water supply passage insertion portion may be an insertion hole having an inner diameter larger than the outer diameter of the flexible tube.

The water supply passage insertion portion can be constructed by removing a part of the rising wall. In this case, the water supply passage is provided with a water discharge unit in which the water discharge port and the water supply passage are integrally formed. The water discharge unit can be detachably attached to the insertion portion.

[0015]

The step of arranging the water supply passage inside the rising wall is provided by providing the water supply passage inserting portion for inserting at least one end of the water supply passage connected to the low tank side into the inside of the rising wall. Since it can be done in, the connection work can be done reliably.

If the water supply passage is a flexible pipe and the inner diameter of the water supply passage insertion portion is larger than the outer diameter of the flexible pipe, the water discharge port is connected to the rising wall in advance in a state of being connected to the water supply passage. It is possible to install the water discharge port. Further, since only the water supply passage having the diameter through which the flexible tube is inserted is formed in the rising wall, the waterproof treatment of the rising wall is simplified and the waterproof effect is improved.

The ball tap 5a is provided with a hose 5b that discharges water directly to the tank body 5 and goes to the handwash bowl 6 as a water supply passage, and the water supply from the ball tap 5a is directly discharged into the tank body 5 and the hose 5b. Parted with what goes to.

The hose 5b is piped along the bottom surface of the hand-washing pot 6 and is connected to the water discharge unit 7 incorporated in the rising wall 6a of the hand-washing pot 6. The water discharge unit 7 can be incorporated in the hand washing bowl 6 in a state of being connected to the hose 5b in advance, and as shown in FIG. 3, a holding seat 6b recessed from the upper end is provided at the center of the rising wall 6a for supplying water. It is formed as a passage insertion part.

As shown in FIGS. 3 and 4, the holding seat 6b has an inner wall that fits the outer shape of the water discharge unit 7 in the width direction, and an opening 6c for passing the hose 5b is formed at the substantially center of the bottom surface thereof. It was opened. Also, the holding seat 6
A drainage port 6e is opened in front of b and at a substantially central position of the ball portion 6d of the hand washing bowl 6, and the drain port 6e is opened below the tank body 5
Face the top of. The drain port 6e is formed in a tubular shape that is slightly elongated downward so that it can be inserted into the opening 5d of the inner lid 5c that covers the upper end of the tank body 5, as shown in FIG. Make sure that the drainage when used does not reach the upper surface of the inner lid 5c.

The water discharge unit 7 may be made of metal or synthetic resin adapted to the hand washing bowl 6, and is provided with a connecting cylinder 7a for connecting the hose 5b at the lower end thereof and a rising wall 6a. The discharge head 7b is provided as a water discharge port on the lower surface of the portion located in front of it when assembled.

As the structure for fixing the water discharge unit 7 to the holding seat 6b, for example, the two examples shown in FIG. 4 can be adopted.

In FIG. 4 (a), the lower half of the connecting cylinder 7a is used as a connecting portion 7c with the hose 5b, and a ridge 7c-1 is formed on the peripheral surface thereof.
Is provided, and the upper half is a large-diameter fixed seat 7d.
The fixed seat 7d has an outer diameter slightly smaller than the inner diameter of the opening 6c of the holding seat 6b, and a peripheral surface thereof is provided with a projection 7e having an outer diameter slightly larger than the opening 6c.
The distance between the upper end of the protrusion 7e and the root of the connecting tube 7a is substantially equal to or slightly larger than the wall thickness around the opening 6c.

In the case of such a water discharge unit 7, the connection cylinder 7a at the lower end thereof is inserted into the opening 6c, and when the projection 7e moves beyond the inner peripheral edge of the opening 6c, the water discharge unit 7 is caused by the snap fit mechanism. Is constrained in the vertical direction with respect to the holding seat 6b. Then, the water discharge unit 7 is incorporated so as to fit the inner wall of the holding seat 6b, so that the position in the left-right direction is also regulated, and the position in the front-back direction is also set by the relationship between the outer diameter of the fixed seat 7d and the inner diameter of the opening 6c. Regulated.

In the example of FIG. 4 (b), a male screw 7f is formed on the outer periphery of the fixed seat 7d in the example of FIG. 4 (a), the male screw 7f is passed through the opening 6c, and the nut 8 is screwed from below. Thus, the water discharge unit 7 can be fixed to the holding seat 6b.

In the above construction, in order to install the water discharge unit 7 in the hand washing bowl 6, in the case of FIG. 4 (a), the hose 5b should be extended from below the opening 6c of the holding seat 6b until it comes out. In this state, the hand washing bowl 6 is fixed to the upper end of the casing 2. Then, the metal clamp ring 9 is externally inserted around the hose 5b, and the connecting portion 7c of the water discharge unit 7 is inserted into the hose 5b. As a result, the hose 5b is restrained in the direction of removal by the protrusion 7c-1 on the peripheral surface of the connecting portion 7c, and at the same time, is crimped and fixed by the clamp ring 9.

As for the connection between the hose 5b and the water discharge unit 7, the connection portion can be worked inside or above the holding seat 6b, so that the operator can visually check the connection status. Therefore, as compared with the case where the connection state by the cap nut 57 cannot be confirmed as in the conventional example, the pipes are connected more reliably and water leakage after assembly is prevented.

When the connection between the hose 5b and the water discharge unit 7 is completed, the water discharge unit 7 is dropped into the holding seat 6b, and the projection 7e of the fixed seat 7d is opened 6 as described above.
Position under c. As a result, the water discharge unit 7 is integrally attached to the hand washing bowl 6.

In this way, as long as the hose 5b is pulled out from the opening 6c, the water discharge unit 7 and the hose 5b are not necessary.
It is possible to perform all the connection from the outside and the incorporation of the water discharge unit 7 into the hand washing bowl 6 by external work. Therefore, as compared with the case of assembling by using a tool on the cap nut 57 in the rising wall 53a as in the conventional example, the work is significantly simplified.

In the example of FIG. 4 (b), since the nut 8 is screwed onto the male screw 7f of the fixed seat 7c, the water discharge unit 7 is held by the holding seat before the hand washing bowl 6 is fixed to the casing 2. It will be incorporated in 6b. That is, FIG.
Similarly to the above example, before pulling up the hose 5b from the opening 6c, the nut 8 is externally attached to the hose 5b, and the hose 5b is connected to the connecting cylinder 7a. And the water discharge unit 7
The nut 8 into the holding seat 6b, and then the nut 8 with the male screw 7f.
The water discharge unit 7 can be fixed to the hand washing bowl 6 by narrowing the upper and lower sides of the holding seat 6b around the opening 6c.

When the nut 8 is used in this manner, the nut 8 and the male screw 7 are looked into while looking into the bottom portion of the handwash bowl 6.
It is necessary to join f. However, since the holding seat 7 is recessed from the upper end of the rising wall 6a and the opening 6c is provided at the lower end thereof so that the nut 8 comes into contact with this portion, the nut 8 is fixed to the hollow rising wall 6a. It is not necessary to insert it deep inside. Therefore, as compared with the conventional structure, the water discharge unit 7 can be assembled more easily, and the connection state between the hose 5b and the connection cylinder 7a can be easily confirmed as in the previous example, so that water leakage after assembly occurs. Nor.

Further, when the water discharge unit 7 is fixed to the holding seat 6b, the water discharge unit 7 itself is raised by the rising wall 6a.
It becomes an assembly which is integrated with and forms a part thereof. Therefore, as compared with a structure in which, for example, the tubular spout is fixed to the front surface of the rising wall 6a alone, local assembly stress is eliminated and the rigidity of the rising 6a is increased to improve its strength. Is planned.

FIG. 5 is a schematic perspective view of a hand washing bowl showing another example.
