2. Description of the Related Art Conventionally, toilet toilets for houses and the like have been improved variously in terms of convenience and hygiene. As one of them, a toilet seat unit incorporating a hot water washing device is known. . As such a toilet seat unit, there are a retrofit type that can be attached to an existing toilet body and an integrated type that is integrally molded with the toilet body. The retrofit type toilet seat unit has the advantage that it can be easily attached to the existing toilet body, but it is inconvenient in terms of design, such as the operation panel protruding to the side of the toilet body or a gap between the toilet tank and the low tank. There was a point.

On the other hand, the integrated toilet seat unit is
Although it cannot be attached to an existing toilet body, and the attachment work must be performed at the time of construction of the toilet bowl, there is an advantage that the retrofit type is not in terms of design, so that the demand is increasing. FIG. 5A is a perspective view illustrating a flush toilet provided with an integrated toilet seat unit.
(B) is a side view of the main portion with a cutout. For example, in the case of this flush toilet (a), a low tank (c) for storing flush water is attached to the toilet main body (a), so wash it with warm water to create a sense of unity with the toilet main body (a). A cover body (e) is provided to cover both the device (d) and the low tank (c). For this reason, it is necessary to remove the cover body (e) or the entire toilet bowl (a) at the time of maintenance of the hot water cleaning device (d), which is not an easy task in a small toilet.

Therefore, as an improvement of this point, a flush toilet bowl as illustrated in FIG. 6 has been proposed. As shown in the exploded side view of FIG. 6 (b), this flush toilet (f) is mounted so that the toilet seat unit (ki) incorporating the warm water washing device (d) straddles the toilet body (a). Therefore, the toilet seat unit (G) can be removed regardless of the presence of the low tank (C).

A flush toilet without a low tank at the rear is extremely advantageous in design as a toilet for integrally mounting a toilet seat unit. For example, in the case of the flush toilet (H) illustrated in FIG. 7, the rear of the toilet body (A) can be widely used as an installation portion for the toilet seat unit (K), and its removal is easy. However, in such a flush toilet without a low tank, it is necessary to supply the toilet flush water directly from the water pipe to wash the toilet using the water pressure. Therefore, in the toilet seat unit
As shown in (b), with the hot water washing device (d),
A flush water supply device (K) is housed, and a water supply pipe (SA) connected to this flush water supply unit (CO) is drawn out to the outside of the toilet seat unit (K). On the other hand, the toilet body (a)
Also, the water supply pipe (s) connected to the rim water passage (s)
Is pulled out to the outside, and if the toilet seat unit (ke) is placed on the toilet body (a) and the water supply pipes (s) and (s) are connected, it will be supplied from the water pipe to the flush water supply device (ko). The supplied water is supplied to the rim water passage (shi) of the toilet body (a) via the water supply pipe (sa) (su), and is discharged from the water spray hole (se) of the rim water passage (shi) to the bowl surface of the toilet bowl. (So) is washed.

[0006]

However, in the case of the conventional flush toilet integrated with the warm water washing device as illustrated in FIG. 7, when the toilet seat unit (K) is attached to the toilet body (A), the water supply is performed. The pipes (s) and (s) had to be connected by screws, etc., and much work and time were required for the installation work, including the water leak inspection after the connection. Further, since the toilet body (a) is also connected to the rim water passage (si) with the water supply pipe (s), the manufacturing is troublesome and the increase in the product price cannot be avoided.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a flush toilet integrated with a hot water washing device which can be easily installed and can be manufactured at low cost. There is.

[0008]

In order to solve the above-mentioned problems, the present invention provides a flush toilet bowl integrally attached with a toilet seat unit equipped with a warm water washing device, wherein toilet flush water supply in the toilet seat unit is provided. A flush toilet integrated with a hot water washing device, characterized in that the tip of the water supply pipe connected to the device is inserted into the rim water passage opening of the toilet body, and the wash water is supplied from this water supply pipe to the toilet body. To do.

Further, in the present invention, the rim water passage opening has an opening area larger than the opening area required for inserting the tip of the water supply pipe, and the amount of water supplied to the toilet flush water supply device is water supply. It is also a preferable embodiment that the amount of water discharged from the pipe is smaller than that.

[0010]

In the flush toilet integrated with the hot water washing device of the present invention, when the toilet seat unit incorporating the hot water washing device and the toilet body are assembled, the tip of the water supply pipe connected to the toilet flush water supply device in the toilet seat unit. By simply inserting the into the opening of the rim water passage of the toilet body, a water passage for flushing water can be secured, greatly simplifying the installation work.

Further, by making the area of the rim water passage opening larger than the opening area required for inserting the tip of the water supply pipe,
Even if the size of the toilet body changes, the tip of the drainage pipe can be reliably inserted. As a result, the assembling work can be easily performed without requiring a high-level alignment technique or the like. Furthermore, by making the amount of water supplied to the toilet flush water supply device smaller than the amount of drainage from the water supply pipe,
Water leakage does not occur even when the area of the rim water passage opening is increased as described above.

The present invention will now be described in more detail with reference to the accompanying drawings showing embodiments.
