Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a toilet bowl having a toilet seat that can be raised and rocked freely.

[Prior Art] Conventionally, as shown in FIG. 3, a toilet with a toilet seat has a support 2 mounted near the rear end of the upper surface of the toilet main body 1, and hinges 3b, 3b of the toilet seat 3 are swung onto the support 2. The toilet seat 3 can be freely pivoted so that the toilet seat 3 covers the opening upper edge 1a of the toilet main body 1 (not shown) when the toilet is used while sitting, and the toilet seat 3 can be raised when a man uses the toilet to urinate. It is configured so that it can be used (as shown). The back surface 3a of the toilet seat 3 has a smooth continuous surface shape except for the cushion portions 5, 5, . . . . In the illustrated example, the toilet seat 3 is in the form of a heating seat with a built-in electric heater (not shown), and 6 in the figure is a wiring cord for the electric heater.

[Problems to be solved by the invention] By the way, when the toilet seat 3 is used while seated, a small amount of urine and/or water may spill out due to splashing from the water surface in the toilet bowl 1b and/or splashing of local washing water. It adheres to the back surface 3a of the toilet seat 3. However, when the toilet seat 3 is raised after sitting, the urine etc. adhering to the back surface 3a of the toilet seat 3 flows down on the back surface 3a in the direction of arrow A.
It travels through the hinge parts 3b, 3b and the wiring cord 6 to the support 2, etc. Therefore, the hinge part 3
b, 3b, Urine scum adheres to the support 2 and the gap between the support 2 and the toilet bowl main body 1, creating an unfavorable sanitary condition, as well as electrical parts for heating control etc. stored inside the support 2. It had a flaw that caused it to corrode.

[Means for Solving the Problems] The present invention is intended to solve the above-mentioned drawbacks, and is to provide a toilet seat with a rear end pivotably supported so that the front end of the toilet seat can be raised and swung freely. In the toilet bowl, a flow prevention wall is protruded near the rear end of the back surface of the toilet seat and extends over approximately the entire width of the back surface on the left and right sides to form a gutter, and a drainage port is formed at an appropriate location in the gutter to form a gutter. The object of the present invention is to provide a toilet bowl with a toilet seat, in which a vertical line hanging down from the drain port passes through the inside of the toilet bowl when the toilet is in an upright position.

[Example] Hereinafter, a toilet bowl with a toilet seat according to the present invention will be described based on an example shown in FIGS. 1 and 2.

The main improvement of the present invention is the back surface 7a of the toilet seat 7.
A flow prevention wall 7c is provided integrally or separately protruding from the rear end of the rear surface 7a over substantially the entire left and right width of the back surface 7a to form a gutter 8.
At the same time, a drain port 8a having an appropriate shape such as a tongue shape is formed at an appropriate location such as the center of the gutter 8, and the drain port 8a hangs down from the drain port 8a when the toilet seat 7 is in the upright position (solid line state in FIG. 2). This is the point where the vertical line V passed through the inside of the toilet bowl 1b. The toilet seat 7 has a top plate 7d.
The invention is not limited to a heating seat type in which an electric heater (not shown) is housed in the cavity 7f formed between the bottom plate 7e and the bottom plate 7e. It can be selected as appropriate from a multi-functional type with a built-in top plate, or a single type consisting of only a top plate. Note that the protrusion dimension H of the gutter 8 is set to a dimension that can ensure a predetermined seated state (the state shown by the two-dot chain line in FIG. 2) when the toilet seat 7 is laid down.

[Function] When the toilet seat 7 is used in the seated state (the state shown by the two-dot chain line in FIG. 2), the back surface 7a of the toilet seat 7 has the following properties:
Urine etc. and/or part of the local washing water that has splashed back from the water surface C in the toilet bowl 1a adheres to the toilet bowl. Next, when the toilet seat 7 is lifted up for the purpose of urinating or cleaning the toilet body, the urine etc. adhering to the back surface 7a of the toilet seat 7 flows down on the back surface 7a in the direction of arrow B (see Figure 1). After being collected in the gutter 8, it is discharged from the outlet 8a into the toilet bowl 1b.

[Effects] The toilet bowl with a toilet seat according to the present invention, when the toilet seat is raised up, drains urine etc. that adheres to the back side of the toilet seat from the outlet into the toilet bowl when the toilet seat is used while sitting. A sanitary condition can be maintained at all times without urine dregs etc. adhering to the support, and it also has the practical effect of not corroding the electrical parts etc. housed in the support.
