The trap section 14 includes a cylindrical drainage section 30 connected to the lower part of the tank body 12, and a cylindrical water sealing section 32 formed within the drainage section 30. A space 34 is formed between the water sealing portion 32 and the edge of the tank body 12 side. The edge of the water sealing part 32 on the tank body 12 side is lower than the connecting part 16 of the drainage part 30, and a water passage 18 is formed above the edge of the water sealing part 32 on the space part 34 side to allow water to flow from the water sealing part 32 to the drainage part 30, The drainage section 30 and the water sealing section 32 are connected at the bottom, and a water sealing area 80 is formed in the water sealing section 32. Between the drainage section 30 and the water sealing section 32, a drainage channel 46 is formed which communicates with the space 34 above the water sealing section 32, The water flowing out from the water seal section 32 into the drain section 30 is guided to the drain outlet section 50 via a drainage channel 46 .

[0011] The trap section 14 is provided with a pipe 60 installed between the drain outlet 20 of the tank body 12 and a pipe attachment section formed on the bottom 40b of the water sealing section 32, which is connected to the bottom 40 connecting the drain section 30 and the water sealing section 32. The water sealing region 80 of the water sealing portion 32 and the water sealing region 80 of the pipe body 60 are in communication with each other.

[0012] The trap portion 14 has an attachment portion 62 for attaching the drainage device 100 on the bottom 40 and / or a pipe body 60 into which the drainage device 100 is loosely inserted, and a gap between the drainage port 20 and the bottom 40 is formed so that various drainage devices 100 can be attached between the drainage port 20 of the tank body 12 and the bottom 40 of the trap portion 14, which are formed with an appropriate gap between them.

[0013] The trap section 14 is configured such that a drain outlet section 50 is disposed on the side of the drain section 30, and water flowing out of the water seal section 32 passes through a drainage channel 46 to reach the drain outlet section 50 and is then drained to the outside.

[0014] The trap section 14 is configured so that a pipe 60 attached between the drain outlet 20 of the tank body 12 and a pipe attachment section 42 formed on the bottom 40 of the trap section 14 can be used to attach various drainage devices 100.

[0015] A drainage device 100 is attached to the drain outlet 20 of the tank body 12, and is configured to guide water flowing in from the tank body 12 through the drainage device 100 to the water sealing section 32.

[0016] (First embodiment) The tank body system 10 is a tank body mechanism with a water sealing function for a washbasin, hand-washing basin, etc., in which a bottomed cylindrical trap section 14 having a connecting section 16 surrounding the drain outlet 20 of the tank body 12 is disposed at the bottom of the tank body 12 around the drain outlet 20 of the tank body 12.

[0017] (tank body) The tub body 12 has a basin or bowl-shaped vessel part 12a constituting a washbasin or hand-washing basin, and a flat vessel bottom part 12b to which a trap part 14 is connected below the basin or bowl-shaped vessel part 12a. The vessel bottom portion 12b has a drain hole 20, which is circular in plan view, penetrating through its center. The tank body 12 is made of ceramic, plastic or metal. In this embodiment, the tank body 12 and the trap portion 14 are connected at a connecting portion 16 and are molded as one piece.

[0018] (Trap section) The trap section 14 is a block-shaped body having a bottomed, cylindrical water-sealing structure with an approximately double-circular cross-section, and is connected to a connecting bottom section 12c on the flat lower surface of the vessel bottom section 12b of the tank body 12 at a connecting section 16 in the upper part of the outermost circumferential wall.

[0019] The trap portion 14 is made of ceramic, plastic or metal, and is integrally molded with the vessel portion 12 a of the tank body 12 . The trap portion 14 is connected to a lower portion of the vessel bottom portion 12b of the tank body 12 and protrudes downward.

[0020] The trap section 14 comprises a cylindrical drainage section 30 connected to the lower part of the vessel bottom section 12b of the vessel section 12a of the tank body 12, and a cylindrical water sealing section 32 formed within the tube of the drainage section 30. The drainage section 30 and the water sealing section 32 are concentric, and the water sealing section 32 is configured such that the inner peripheral wall section 36, which is a cylindrical section with a circular cross section and which constitutes the water sealing section 32, is arranged at an appropriate interval inside the outermost cylindrical outer wall section 38, which is a cylindrical section with a circular cross section and which constitutes the water sealing section 32, so that a water sealing area 80 is formed inside the inner peripheral wall section 36.

[0021] The edge of the inner wall portion 36 constituting the water sealing portion 32 on the side of the connecting portion 16 is lower than the connecting portion 16 of the outer wall portion 38 constituting the drainage portion 30, and a space 34 is formed between it and the underside of the vessel bottom portion 12b of the tank body 12 at the upper part.

[0022] A bottom portion 40 is formed below the outer peripheral wall portion 38 constituting the drainage portion 30 and below the inner peripheral wall portion 36 constituting the water sealing portion 32 . The bottom 40 has a bottom portion 40b formed on the lower side of the cylindrical inner wall portion 36 having a circular cross section and constituting the water sealing portion 32, and a through hole which is a pipe mounting hole which constitutes the mounting portion 42 is drilled therein. The through hole constitutes an attachment portion 42 for attaching the drainage tool 100 and / or the pipe body 60, and is formed so as to face the drainage outlet 20 formed in the vessel bottom portion 12b of the tank body 12. The through holes and drain outlet 20 that constitute the mounting portion 42 are arranged concentrically about the center line X-X1 that passes through the centers of the tank body 12 and the trap portion 14, and are composed of holes that are approximately the same shape and circular when viewed in a plan view. Therefore, the cylindrical pipe body 60, which will be described later, is inserted into the drain outlet 20 and the through hole, which is a pipe mounting hole that constitutes the mounting portion 42 at the bottom 40b of the water sealing portion 32, and is bridged between the tank body 12 and the water sealing portion 32 of the trap portion 14.

[0023] The trap portion 14 has an attachment portion 42 on the bottom 40 for attaching the drainage device 100 formed in correspondence with the external shape of the various drainage devices 100, and a distance between the drainage port 20 and the bottom 40 is formed so that various drainage devices 100 can be attached between the drainage port 20 of the tank body 12, which is formed with an appropriate distance between the trap portion 14 and the bottom 40 of the trap portion 14.

[0024] The trap section 14 is formed into a cylindrical body having a shape corresponding to the outer shape of various drainage tools 100, with the tube body 60 attached between the drain outlet 20 of the tank body 12 and the tube body 60 formed on the bottom 40 of the trap section 14 and a tube mounting hole constituting the mounting section 42 for attaching the drainage tool 100, so that the various drainage tools 100 can be attached to the internal space of the tube.

[0025] In the first embodiment of the present invention, the diameter of the through hole constituting the mounting portion 42 having a circular cross section for mounting the pipe body 60 formed on the bottom 40 is formed slightly larger than the outer shape of the drainage device 100, and the pipe mounting hole constituting the mounting portion 42 of the bottom 40a is a circular through hole slightly larger than the outer shape of the pipe body 60, and its diameter is formed slightly larger than the outer shape of the pipe body 60.

[0026] The outer peripheral wall portion 38 constituting the drainage section 30 and the inner peripheral wall portion 36 constituting the water sealing section 32 are connected by the bottom 40a of the drainage section 30, which constitutes the bottom 40 of the trap section 14, and the bottom 40a is connected to the bottom 40b constituting the bottom 40 of the water sealing section 32.

[0027] A bottom 40a, which is installed between the outer peripheral wall portion 38 constituting the drainage section 30 and the inner peripheral wall portion 36 constituting the water sealing section 32, seals the space between them, and a drainage channel 46, which constitutes the water passage 18 communicating with the drainage outlet portion 50, is formed between the outer peripheral wall portion 38 constituting the drainage section 30 and the inner peripheral wall portion 36 constituting the water sealing section 32.

[0028] The bottom 40a connecting the drainage section 30 and the water sealing section 32 is formed lower than the bottom 40b of the water sealing section 32, so that water accumulating in the drainage channel 46 formed between the outer peripheral wall section 38 constituting the drainage section 30 and the inner peripheral wall section 36 constituting the water sealing section 32 does not flow back into the water sealing section 32.

[0029] The trap section 14 has a through hole formed in the bottom 40b of the water sealing section 32 which is connected to the bottom 40a which connects the drain outlet 20 of the tank body 12 and the outer peripheral wall section 38 which constitutes the drainage section 30 and the inner peripheral wall section 36 which constitutes the water sealing section 32, and a pipe mounting hole which constitutes the mounting section 42 is formed, and a pipe 60 is installed between the through hole which constitutes the mounting section 42 and the drain outlet 20 of the vessel bottom 12b of the tank body 12.

[0030] The trap section 14 is configured such that a drain outlet section 50 is arranged on the side of the outer peripheral wall section 38 that constitutes the drainage section 30, and water flowing out of the water sealing section 32 passes through a drainage channel 46 to reach the drain outlet section 50 and is drained to the outside.

[0031] The water that accumulates in the water seal 32 is discharged through a trap Department It decreases due to pressure fluctuations and evaporation in the waterway inside 14. Therefore, the water sealing depth (vertical distance from the wear to the dip) of the trap part 14 is set to 50 mm or more and 100 mm or less.

[0032] In this embodiment of the present invention, the water sealing portion 32 of the trap unit 14 has a water sealing region 80 (first water sealing region 80a) formed inside a cylindrical inner circumferential wall portion 36 having a circular cross section. The pipe body 60 has a water sealing region (second water sealing region 80b) formed in its upper portion, i.e., the region above the bottom 40b of the water sealing section 32, and a water sealing region 80 (third water sealing region 80c) formed in the region below the bottom 40b of the water sealing section 32. In this embodiment of the present invention, the water sealing region 80 (first water sealing region 80a) of the water sealing portion 32 of the trap portion 14 and the water sealing region 80 (second water sealing region 80b and third water sealing region 80) of the pipe body 60 are c), and the water depth (between the upper part of the water sealing section 32 and the cap 76 (constituting the bottom 40) of the drainage section 30 that constitutes the water sealing area 80 (third water sealing area 80c) of the pipe body 60) is configured to be 50 mm or more and 100 mm or less. The tank body system 10 according to the first embodiment of the present invention is excellent in water sealing strength, that is, the ability of the trap portion 14 to retain water sealing when positive or negative pressure occurs in the drain pipe.

[0033] A water passage 18 is formed in the space 34 above the edge of the water sealing part 32 on the connecting part 16 side. The water passage 18 formed in the space 34 is a water passage for guiding water overflowing from the water sealing part 32 to a drainage channel 46 formed inside the drainage part 30.
