Description

The present invention relates to a tank system, and particularly relates to a tank system including a tank such as a washbasin or hand wash basin having a water sealing (trap) function.

Conventional water sealing (trap) structures include siphon type traps such as S traps and P traps, and non-siphon type traps such as bowl traps and drum traps. These are U-shaped items that require space in the vertical direction, and need to be stored inside a dressing table, for example, but this reduces the storage space.
Currently, there is a need to install wash basins and hand wash basins in various places to prevent infection by viruses and other diseases. In particular, there is a demand for devices that do not require space like S-traps and P-traps, but can be installed directly in shoe cabinets, washstands, vanities, etc.

In the tank system 10 of the fourth embodiment, the vessel part 12a and the vessel bottom part 12b are the same as those in the first embodiment, except for the drain port 22, the overflow water drainage channel 22a, and the ridges 22b. 12a and the bottom part 12b.
The trap section 14 has the same configuration as the trap section 14 disposed in the tank body 12 of the first embodiment, except for the connection part with the overflow water drainage channel 22a.
Further, the tubular body 60 has the same configuration as the tubular body 60 in the first embodiment.
The structure for attaching the tube body 60 to the vessel bottom portion 12b and the trap portion 14 using the attachment member 64 is also the same as that of the first embodiment.
The mounting member 64 includes a lock nut 66, a sliding packing 68, a triangular packing 70, a sponge packing 72, a packing 74, and a cap 76 (constituting the bottom portion 40).

In the fourth embodiment, a protruding line 22b is formed on the outer circumferential surface of the vessel part 12a of the tank body 12, which connects the overflow hole 22 to the outer circumferential wall part 38 of the trap part 14.
The protruding strip 22b is an elongated convex body that protrudes from the outer circumferential surface of the vessel portion 12a, and is connected to a recessed portion 38a formed in a part of the outer circumferential wall portion 38.
The overflow water drainage channel 22a formed between the protrusion 22b and the container part 12a is connected to the inner peripheral wall part 36, and is formed so that the overflow water flowing from the overflow water drainage channel 22a flows into the water sealing part 32. has been done.

The outer peripheral wall portion 38 is connected to the vessel bottom portion 12b at the connecting portion 16 at the upper end of the recessed portion 38a and at the connecting portion 16 in the area other than the recessed portion 38a.
The inner peripheral wall portion 36 has the same structure as the trap portion 14 disposed in the vessel bottom portion 12b of the first embodiment, except that an overflow water drainage channel 22a is formed in a part of the inner peripheral wall portion 36.

The tubular body 60 has the same configuration as the tubular body 60 of the first embodiment, and is attached to the trap section 14 in the same manner.

The water accumulated in the water sealing part 32 decreases due to pressure fluctuations in the water channel in the trap part 14, evaporation, and the like. Therefore, the water sealing depth (vertical distance from the wear to the dip) of the trap section 14 is set to 50 mm or more and 100 mm or less.

In the fourth embodiment of the present invention, the water sealing part 32 of the trap part 14 has a water sealing area 80 (a first water sealing area 80a) is formed.
In the pipe body 60, a water sealing area (second water sealing area 80b) is formed in the upper part, that is, a region above the bottom part 40b of the water sealing part 32, and a water sealing area (second water sealing area 80b) is formed above the bottom part 40b of the water sealing part 32. In the lower region, a water sealing region 80 (third water sealing region 80c) is formed.
In the fourth embodiment of the present invention, the water sealing area 80 (first water sealing area 80a) of the water sealing part 32 of the trap part 14 and the water sealing area 80 (second water sealing area 80b and The third water sealing area 80c) is connected to the deep water depth (the upper part of the water sealing part 32 and the bottom part of the drainage part 30 that constitutes the water sealing area 80 (third water sealing area 80c) of the pipe body 60). 40 and the cap 76) is configured to be 50 mm or more and 100 mm or less.
The tank system 10 according to the fourth embodiment of the present invention has excellent water sealing strength, that is, the ability of the trap section 14 to maintain a water seal when positive pressure or negative pressure is generated in the drain pipe. .

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

(water flow)
In the tank system 10 of the fourth embodiment, the water that has flowed into the tube body 60 from the vessel part 12a of the tank body 12 flows downward inside the tube body 60 and flows into the tube body 60, as shown in FIG. 3 When the water flows into the inside of the pipe body 60C, it rises upward, flows into the water sealing part 32 through the water passage opening 62b, reaches the water sealing area 80 of the water sealing part 32, reaches the drainage part 30, and drains into the water outlet. Flows from section 50 to the outside.
Further, the overflow water flowing from the overflow water drainage channel 22a flows into the water sealing area 80 in the inner peripheral wall part 36, reaches the water sealing area 80 of the water sealing part 32 to the drainage part 30, and is discharged from the drainage port part 50 to the outside. flows out.
Then, a certain amount of water flows into the water sealing area 80 (first water sealing area 80a) of the water sealing part 32 and the water sealing area 80 (second water sealing area 80b, third water sealing area 80c) of the pipe body 60. It stays inside and becomes a water seal.

The tank system 10 according to the present invention is formed with a trap section 14 and a pipe body 60 so that various known drainage tools can be attached thereto.
The trap part 14 has a width of a pipe attachment hole drilled in the bottom part 40 (40b) of the water sealing part 32 for attaching the drainage tool 100 and the bottom part 40 (40b) of the water sealing part 32 for attaching the drainage tool 100. W2 is formed to have a length wider than the maximum width W1 of the drainage tool 100.
The tubular body 60 is formed so that the inner diameter W4 and the outer diameter W5 of the cylindrical portion 62d are slightly longer than the maximum width W1 of the drainage tool 100.
The trap part 14 is formed so that the width W3 of the drain port 20 formed in the bottom part 12b and the width W2 of the pipe attachment hole formed in the bottom part 40 (40b) are wider than the maximum width W1 of the drain tool 100. has been done.

As described above, the embodiment of the present invention has been disclosed in the above description, but the present invention is not limited thereto.
In other words, various modifications can be made to the above-described embodiments in terms of mechanism, shape, material, quantity, position, arrangement, etc. without departing from the scope of the technical idea and purpose of the present invention, and these are included in the present invention.
