DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a drain trap in a sink or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in a sectional view of a main part in FIG. 3 , a wash basin 51 is installed on a floor surface F in such a manner that a back plate 4 is in contact with a wall surface W, A wash basin 52 is provided above the wash basin 51, and a lower portion of the wash basin 52 is a storage space S provided with a door 53 that can be opened and closed on the front surface. A trap pipe 55 is provided vertically, and an upper end of the drain trap pipe 55 is provided with a cap nut 5.
4 is connected to the drain 52a of the basin 52 via
The lower end of the drain trap pipe 55 is connected to a drain pipe 56 buried in the floor F, and the drain trap pipe 55 has a U-shaped water seal portion 55a formed therein. Water sealing water is always stored in the water sealing portion 55a to suppress the rise of odors and pests rising from the drain pipe 56 to the basin 52. In such a conventional structure, kitchen utensils and the like are stored in the storage space S. However, since the drain trap pipe 55 is installed vertically in the storage space S, the storage volume in the storage space S is reduced. It is difficult to store large items, and only small items can be stored. Sewage flowing in the drain trap pipe 55 is close to the items stored in the storage space S. This caused discomfort. Further, the conventional drain trap tube 55 is attached to the drain port 52a of the wash basin 55 in a hanging manner via the cap nut 54, and there is a problem that the mounting strength becomes unstable.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems. A first gist of the present invention is to surround a back plate constituting a cabinet such as a wash basin with a frame plate. It is formed in the shape of a hollow panel, a partition plate is disposed in the hollow portion of the panel, a trap passage having a water seal portion is integrally formed in a back plate, and a wash basin or the like is provided at an upper end side of the trap passage. An upper hole that can communicate with the drain port is formed, and a lower hole that can communicate with a drain pipe such as a floor is formed at the lower end side of the trap passage. A second gist is that the trap passage is provided with a pair of hanging plates vertically arranged in a lower portion of an upper frame of a back plate, and a U-shaped U-shape provided in a lower portion of the hanging plate. A water seal portion is formed between the plate and the U-shaped plate, and is formed of a pair of guide plates vertically arranged in a Y-shape below the U-shaped plate.

[0004]

[Function] When the back plate itself is assembled as a component of the cabinet, the trap piping is completed at the same time, so that the assembling is easy and the piping work is extremely easy, and since the trap portion is not exposed, the wash basin has a neat external shape. Thus, an extremely large storage space in the cabinet can be ensured, and a large-sized object can be stored in the storage section satisfactorily.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, the cabinet of the sink 51 is shown.
In FIG. 1 , a trap tube is formed integrally in a back plate 4 constituting a back surface . In FIG. 1 , a trap passage R is formed in a panel constituting the back plate 4, A passage 21 is formed between the hanging plate 21 and the side frame 22, and a basin 5 is provided at an upper end of the passage.
2 and a drain upper hole 27 which can be communicated via a connection pipe (not shown)
A horizontal plate 23 is disposed horizontally below the hanging plate 21 so as to form a passage, and a right end of the horizontal plate 23 is vertically raised from the lower frame 25. Rising plate 24
Is formed between the upper portion of the rising plate 24, the hanging plate 21, the horizontal plate 23, and the side frame 22.
Is formed, and the water seal portion Ra
And a trap passage R between the rising plate 24 and the side frame 26.
There are formed, Do shown at the lower end of the trap passage R
Drainage hole 2 that communicates with and connects to the drainage pipe 56 via a connecting pipe
8 is integrally formed. The back plate 4 can be formed into a panel by integrally forming a trap passage R therein with resin, and drainage from the basin 52 passes through the drain upper hole 27, passes through the water sealing portion Ra, and passes through the trap passage R. Water is drained from R through a drainage hole 28 to a drainage pipe 56 buried in a floor or the like, and water is sealed in a water seal Ra.

In such a structure of the back plate 4, when the back plate 4 itself is assembled as a component of the cabinet of the wash basin 51, the trap piping is completed at the same time, so that the assembling is easy and the piping work becomes extremely easy. ,
In addition, since the trap portion is not exposed, the wash basin has a neat external shape, so that the storage space S in the cabinet can be extremely widened, and large items can be stored in the storage space S favorably. Become.

In FIG. 2 , a trap is integrally formed in the back plate 4, and a pair of hanging plates 31 are formed in the lower part of the upper frame 20 in a vertically parallel manner. A drain upper hole 27 is formed in the upper part between the 31, 31 and a U-shaped U-shaped plate 32 is arranged below the hanging plates 31, 31, and a pair of Y-shaped is formed in the lower part of the U-shaped plate 32. Guide plates 33, 3
3 is formed, and a lower drainage hole 28 is formed in the lower frame 25 between the guide plates 33, 33.

In such a structure, the U-shaped plate 3
A water sealing portion Ra is formed by the pair 2 and the pair of hanging plates 31, 31. A cleaning drain hole 29 can be formed in the water sealing portion Ra. Also in this example, the trap passage R is formed by a resin or the like in the back plate 4 in a pair, so that the wash basin is made extremely compact and refreshing without the need for a separate trap pipe 55. Thus, the storage space S can be formed extremely wide.

[0009]

According to the present invention, a back plate constituting a cabinet such as a wash basin is formed in a hollow panel shape surrounded by a frame plate, and a partition plate is disposed in a hollow portion of the panel to form a water seal. A trap passage having a portion is integrally formed in the back plate, an upper hole is formed at an upper end side of the trap passage so as to communicate with a drain port of a wash basin, and a lower end side of the trap passage communicates with a drain pipe such as a floor surface. By forming a pilot hole that can be formed, trap piping is completed at the same time when the back plate itself is assembled as a component of the cabinet, easy to assemble, piping work is extremely easy, and because the trap part is not exposed, it is neat The wash basin has an external shape, and the storage space in the cabinet can be extremely widened, so that a large-sized object can be stored in the storage portion. In addition, the trap passage, a pair of hanging plates disposed in the vertical direction in the lower part of the back plate upper frame,
A U-shaped U-shaped plate provided at the lower part of the hanging plate, and a pair of Y-shaped vertically formed water sealing portions formed between the U-shaped plate and the lower part of the U-shaped plate. By using the guide plate of the above, the wash basin can be made extremely compact and refreshing without the need for a separate trap pipe, and the storage space can be formed extremely wide.
