Description

The present invention is based on the concept of “not arguing too much and harmonize with the space”, and in order to realize this, the lines, irregularities, and pipes that cause noise (disturbance) are eliminated as much as possible, and space saving is pursued. It is a flush toilet.

In the 1990s, the applicant released the first toilet in the world to wash away filth using the pressure of water supply. Since there was no tank for storing flush water, which was essential for previous flush toilets, it was called “tankless toilet” in the market.
The applicant has pioneered a new market for tankless toilets and has always led the market.

Later, with the expansion of the market and the entry of late-stage manufacturers, the latest tankless toilets have accelerated manufacturing that gives priority to functionality and high-tech. In the toilet space where elements such as “relaxation” and “relaxing space” are originally required, the existing tankless toilet has disturbed the harmony of the space (for example, see Patent Document 1).

The overall configuration of the flush toilet according to the present embodiment will be described below with reference to FIGS. 1, 2 and 9 which are perspective views showing the entire flush toilet according to the present invention.

Reference numeral 1 denotes a flush toilet according to the first embodiment of the present invention, which is used by being attached to a floor surface of a toilet space.
On the upper surface of the toilet body 1, a toilet seat 5 having a hot water washing function for washing a user's local part and a toilet lid 3 covering the toilet seat 5 are attached.
Behind the toilet body 1 is provided with a casing 4 containing a functional part of the hot water washing function, and on the right side surface thereof is provided with a warm air outlet 6 for warming the toilet space.

Wash water for washing away the filth is supplied to the toilet body 1 from a water pipe (not shown), and is discharged so as to generate a swirling flow in the bowl portion 7 of the toilet using the water pressure of the water. Subsequent to this operation, the washing water is vigorously supplied toward the trap channel 8 provided in the toilet main body, thereby causing a siphon phenomenon in the trap channel and guiding the filth to the drainage pipe.

The toilet body 2 is watertightly connected to a drainage pipe arranged upright from a floor via a flexible pipe (not shown), and is detachably fixed to the floor by bolts and nuts.

Next, the configuration of the present invention will be described with reference to FIGS.

Aiming at a tankless toilet that harmonizes with the space, the present invention reduces the “waste line”, “gap”, and “unevenness” to the limit, and pursues the simple and elegant form that only the tankless toilet has. I challenged the field of manufacturing.
First, we started the structural design of the top view (plan view) of the toilet that is most visible to the user. Since the tankless toilet is equipped with a warm water flush toilet seat, the top view naturally has a toilet seat cover (toilet lid) in the front, and the warm water flush toilet seat in the back, and the cover hinge and infrared sensor A black window and an operating status display unit (LED) lie down.

Based on these basic configurations, as shown in FIGS. 4 to 6, in the present invention, the hinge structure is covered with the toilet lid 3 to eliminate its presence, and a red light transmitted from a remote controller (not shown) is used. By providing the light receiving portion for the external light signal on the back side 4b of the casing 4 that is difficult to touch the user's eyes, "waste lines", "gap", and "unevenness" that become noise from the top view of the toilet are reduced.

Next, as apparent from FIG. 4, both the rear edge shape 3 a of the toilet lid 3 and the rear edge shape 4 a of the casing 4 are configured to be gently curved. As the most preferable mode, it is desirable to form the curved shape of the trailing edge shape 23a of the toilet lid 23 and the trailing edge shape 24a of the casing 24 with substantially the same curvature as in the second embodiment shown in FIGS. . Further, as in the third embodiment shown in FIGS. 20 to 28, both the rear edge shape 33a of the toilet lid 33 and the rear edge shape 34a of the casing 34 have a gentle curved shape, and are formed on the top 34c. The ridgeline can also be a gentle curve. Furthermore, the curvature of the trailing edge shape 44a of the casing 44 can be made larger than the curvature of the trailing edge shape 43a of the toilet lid 43 as in the fourth embodiment shown in FIGS. By forming in this way, two curved shapes resonate and a soft impression can be given to the user.

The rear part of the toilet lid 3 is arranged so as to overlap the front part of the casing 4. By adopting such an arrangement structure, it is possible to prevent the generation of a large groove that occurs at the boundary between the toilet lid and the casing, which is often found in conventional tankless toilets.
Further, as shown in FIG. 5 or FIG. 6, the rear portion of the side surface shape of the toilet lid 3 adopts a shape synchronized with the side surface shape of the casing 4.

Further, as can be seen from FIG. 2, since the toilet lid 3 configured as described above can be reduced in depth, the vertical space is not compressed even when the toilet lid 3 is opened.

Further, the back surface portion 4b of the casing 4 is inclined forward. By setting the inclination angle to be relatively standing, it is possible to make the back portion 4b of the casing 4 invisible to the user standing in front of the flush toilet 1. By comprising in this way, from the user, the top part 4c (ridge line in the highest position) of the casing 4 causes an illusion with the deepest part of the flush toilet. As a result, the user feels the depth dimension of the flush toilet of the present invention shorter than the actual dimension, and can eliminate the feeling of pressure in the toilet space. A similar effect is obtained by forming the back surface portion 54b of the casing 54 with a curved surface as in the fifth embodiment shown in FIGS. 38 to 46, and inclining the front side, as in the sixth embodiment shown in FIGS. In this way, the back surface portion 64b of the casing 64 is configured to have a planar shape and is inclined forward, and the inclined surface of the back surface portion 74b of the casing 74 is first implemented as in the seventh embodiment shown in FIGS. It is also possible to produce an aspect in which it is wider than the shape and inclined forward.
