The action and effect of the flush toilet 1 according to this embodiment will be described. The flush toilet 1 includes a toilet bowl portion 10, a trap portion 20, and an outer peripheral wall portion 40. - 特許庁The trap part 20 continues to the lower end of the toilet bowl part 10 . In the installed state of the flush toilet 1, the outer peripheral wall portion 40 surrounds the toilet bowl portion 10 and the trap portion 20 over the entire front, rear, left, and right circumferences, and is arranged on the floor surface. The flush toilet bowl 1 is made of pottery in which the toilet bowl portion 10, the trap portion 20 and the outer peripheral wall portion 40 are integrally formed. The outer peripheral wall portion 40 has an opening 40</b>A formed at its rear portion for passing the connection pipe P connected to the lower end of the second descending flow path 23 that is the downstream end of the trap portion 20 .

The flush toilet bowl 1 is given a good design by the outer peripheral wall portion 40 surrounding the toilet bowl portion 10 and the trap portion 20 over the entire circumference. The flush toilet 1 has an opening 40A for the connecting pipe P to pass through at the rear portion of the outer peripheral wall portion 40. As shown in FIG. Therefore, the flush toilet 1 can realize a well-designed flush toilet compatible with the above-floor drainage system.

The outer peripheral wall portion 40 has an opening 40A as a second opening formed in the rear portion thereof. The opening 40</b>A is provided for drawing the water supply hose H and the power cord C inside the outer peripheral wall portion 40 . Therefore, in the flush toilet 1, the water supply hose H and the power cord C can be routed well, and a good design with a clean appearance can be obtained.

Aperture 40A functions as both a first aperture and a second aperture according to the present disclosure. For this reason, the flush toilet 1 can reduce the number of openings compared to the case where the opening for the connection pipe and other openings for the water supply hose, the power cord, etc. are separately provided, and the outer peripheral wall portion can be It is possible to suppress deterioration of aesthetic appearance.

The flush toilet bowl 1 has a support wall portion 60 . The support wall portion 60 supports the trap portion 20 by connecting the trap portion 20 and the outer peripheral wall portion 40 . Therefore, the flush toilet 1 can ensure the strength of the trap portion 20 . Since the flush toilet 1 is provided with the support wall portion 60, the strength of the outer peripheral wall portion 40 can also be ensured.

The opening 40A is continuous with the support wall portion 60 . Therefore, the flush toilet 1 can secure the strength of the peripheral edge portion of the opening 40</b>A in the outer peripheral wall portion 40 . For example, if the opening formed in the outer peripheral wall is not continuous with the support wall, the strength of the peripheral edge of the opening depends only on the strength of the outer peripheral wall. On the other hand, in the case of the present embodiment, the strength of the peripheral portion of the opening 40A is due to the outer peripheral wall portion 40 and the support wall portion 60, so that the strength can be further improved.

The height of the upper end edge of the opening 40A is the same height as the lower surface of the upper support wall portion 61 in the support wall portion 60 . That is, the height of the upper end edge of the opening 40A is ensured within 50 mm below the lower end edge of the upper support wall portion 61 in the support wall portion 60 . Therefore, in the flush toilet 1, a sufficient size of the opening 40A is ensured, and the opening 40A is formed at a good height that is not too low, so that the connecting pipe P can be easily passed through.

The flush toilet 1 has a support portion 70 . The support portion 70 is provided within the opening 40A. The support portion 70 supports the water supply hose H and the power cord C. As shown in FIG. Therefore, in the flush toilet 1, the wiring routes of the water supply hose H and the power cord C can be well regulated.

The support wall portion 60 forms a through hole 60A. A water supply hose H and a power cord C are passed through the through hole 60A. 60 A of through-holes and 40 A of openings overlap with the front-back direction in the planar view at the time of installation. Therefore, in the flush toilet 1, the water supply hose H and the power cord C drawn inside from the opening 40A can be smoothly passed through the through hole 60A.

The water supply hose H and the power cord C, which are passed through the opening 40A, are passed below the connecting pipe P, respectively. As a result, the flush toilet 1 can effectively utilize the space below the connection pipe P in the opening 40A. For example, the height of the drainage pipe on the rear wall surface is determined to some extent, such as 155 mm. For this reason, the height position of the connection pipe P is also determined according to the specifications, and it is difficult to dispose the connection pipe P in a downward direction. In this embodiment, the space in the opening 40A can be effectively used by passing the water supply hose H and the power cord C through the space below the connection pipe P in the opening 40A.
