Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a local cleaning device.

[0002]

2. Description of the Related Art Conventionally, a local washing mechanism provided in a Western-style toilet body and capable of washing a local part of a human body, and a water supply which is directly connected to a water pipe for supplying washing water from the outside and connects the water pipe and the local washing mechanism. A local cleaning device provided with a mechanism is known.

[0003] Here, the local cleaning mechanism has a hot water tank capable of heating while storing the cleaning water. The water supply mechanism has a built-in solenoid valve and a flow control valve so that the washing water supplied from the water pipe can be appropriately replenished to the hot water tank, and the hot water in the hot water tank is thus refilled with the washing water. Thus, it is ejected from the nozzle of the local cleaning mechanism.

In this local cleaning device, an opening for draining water is provided at the bottom of the hot water tank so as to be openable and closable, and by opening the opening, a water channel such as a nozzle in the hot water tank and a nozzle downstream thereof is provided. It is possible to drain the washing water inside. Thus, in a case where the unused state is continued under a low temperature condition such as a cold region, freezing of the washing water inside these is prevented, and the next suitable use is enabled.

[0005]

However, in the above-mentioned conventional local cleaning device, the hot water tank is provided with an opening for draining water, so that the structure of the hot water tank is complicated and the production cost is increased. .

The present invention has been made in view of the above-mentioned conventional circumstances, and has as an object to solve the problem of providing a local cleaning apparatus capable of reducing the manufacturing cost.

[0007]

A local cleaning device of the present invention is provided in a Western-style toilet bowl main body and is directly connected to a local cleaning mechanism capable of cleaning a local part of a human body with cleaning water and a water pipe for supplying cleaning water from outside. A water supply mechanism for connecting the water pipe and the local cleaning device, wherein the local cleaning mechanism stores a hot water tank that can be heated while storing the cleaning water supplied from the water pipe via the water supply mechanism. Having a local cleaning device,

The water supply mechanism has a communication passage communicating with the bottom of the hot water tank, and is provided in the communication passage so as to be openable and closable for draining water.

In the local cleaning device of the present invention, since the communication passage of the water supply mechanism can be opened and closed for drainage, it is not necessary to provide an opening for drainage in the hot water tank, and the structure of the hot water tank is simplified. The manufacturing cost can be reduced.

However, when the communication passage of the water supply mechanism can be opened and closed for drainage in this way, the structure of the water supply mechanism itself is unavoidably more complicated than before. However, the water supply mechanism originally has a complicated structure including a solenoid valve and a flow control valve in order to appropriately replenish the washing water supplied from the water pipe into the hot water tank. For this reason, even if the communication passage of this water supply mechanism is made openable and closable, there is no significant increase in cost. On the other hand, the cost can be greatly reduced by omitting the opening of the hot water tank.

Therefore, the local cleaning device of the present invention can reduce the manufacturing cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a shower toilet 2 which is a local cleaning device and a toilet cleaning device of the embodiment is attached to a ceramic Western-style toilet body 1 to constitute a Western-style flush toilet.

As shown in FIG. 2, the shower toilet 2 includes a front base plate 2a, a local cleaning mechanism 2b such as a nozzle fixed on the front base plate 2a, a rear base plate 2c, and a rear base plate 2c. , A hot water tank 2d constituting the remainder of the local cleaning mechanism 2b, a toilet cleaning mechanism 2e such as a valve fixed on the rear base plate 2c, and a hot water tank 2d and a toilet cleaning mechanism 2e fixed to the rear base plate 2c. A water supply mechanism 2f capable of supplying washing water to the rear base plate 2c;
A concealing member 2g which is erected around the entire circumference in the horizontal direction and surrounds the hot water tank 2d, the toilet flushing mechanism 2e, and the elevating mechanism;
The upper cover 2 containing the local cleaning mechanism 2b and the like.
h, an under cover 2i, a heating toilet seat 2j swingably provided on the upper cover 2h, and an upper cover 2j.
h and a toilet lid 2k that is swingably provided.

The hot water tank 2d has a heater and a thermostat (not shown) and can be heated while storing cleaning water. The water supply mechanism 2f has a flexible hose 3 connected at one end to a water supply pipe (not shown) for supplying cleaning water from the outside by a clip 6, and the other end is branched from the main pipe 21 connected to the toilet flushing mechanism 2e. A branch pipe 22 and a water supply device 23 connected to the lower side of the branch pipe 22 and also connected to the bottom of the hot water tank 2d at the lower side.

As shown in FIG. 3, the water supply device 23 has a water supply main body 23a and a pipe 23b projecting horizontally from the water supply main body 23a toward the hot water tank 2d. As shown in FIG. 4, a solenoid valve 25, a flow control valve 26, and a strainer (not shown) are built in the water supply main body 23a. A communication passage 24 connected to the branch pipe 22 is formed in the water supply main body 23a. The communication passage 24 is connected to an electromagnetic valve 25 via a strainer, and then connected to a flow control valve 26. It is going straight inside 23b. The tube portion 23b is
As shown in FIG. 5, the hot water tank 2 is
It is inserted into an insertion opening 28 formed at the bottom of the part d.

The water supply device 23 is shown in FIGS.
As shown in (2), a drain cap 23c is screwed near the boundary between the water supply main body 23a and the pipe portion 23b. When the drain cap 23c is removed, the communication passage 24 is opened for draining. At the lower end of the water supply device 23, the strainer cap 23 projects from the lower surface of the under cover 2i.
d is screwed, and the strainer can be taken out by removing the strainer cap 23d.

The shower toilet 2 configured as described above
In the Western-style flushing toilet provided with, the local washing mechanism 2b of the shower toilet 2 can wash the local part of the person seated via the heating toilet seat 2j. At this time, the water supply device 23 appropriately replenishes the washing water supplied from the water pipe via the flexible hose 3 to the hot water tank 2d, and the hot water in the hot water tank 2d is washed by the washing water thus supplemented by the local washing mechanism 2.
