Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a drainage basin used for floors on which water flows, such as bathrooms and shower rooms.

[Prior Art] Water-sealing traps with insect- and odor-proofing measures are used at the drains of bathroom washrooms and shower rooms to prevent insects and bad odors from coming up from the sewage. However, this trap had poor drainage efficiency, and if the amount of drainage was too large or hair accumulated in the round tray, the drainage would become stagnant and the area around the drain would become filthy.

Therefore, the inventor of this invention developed a drainage basin that was buried in the floor of the washing area and allowed wastewater to flow into it rapidly, thereby preventing wastewater from accumulating in the washing area even if a trap was used at the drain outlet. -It has already been proposed in Publication No. 186393.

The drainage basin described in the above-mentioned publication is usually made of stainless steel plate or synthetic resin from the viewpoint of preventing rust. Further, the lid, which is fitted into the drainage basin and has a generally U-shaped cross section, is usually made of a stainless steel plate in order to prevent rust and to ensure strength and safety when people ride on the lid.

[Problems to be solved by the present invention] The main body of the drainage basin described above is used by being buried in the floor of a bathroom, etc., but when doing so, concrete or mortar is used, and during the burying work, these can be buried in the drainage basin body. Mortar and concrete will stick to it. If the main body of the drainage basin is made of a metal plate such as a stainless steel plate, there is no problem because it is easy to remove even if it adheres. However, if the main body of the drainage basin is made of synthetic resin, it is difficult to remove mortar or concrete if it adheres to it, and even if it does come off, it will leave traces. There is not much of a problem if the mortar or concrete is attached to a part of the drainage basin that is buried or hidden from view by a lid. However, there is a problem in that the flange surface is visible even after burial, making it unsightly.

In addition, when the lid is made of a stainless steel plate, the flange surface and the lid look different and lack a sense of unity.

[Means for solving the problems] The present invention solves the above problems. (a) A metal lid is removably provided at the opening of the drainage basin main body which is open at the top; b) The main body of the drainage basin is molded from synthetic resin and has a flange formed at the upper end, and at least the surface of the flange is covered with a metal plate; (c) The bottom of the main body of the drainage basin has a drain opening into which a trap is attached. This drainage basin is characterized in that the wastewater flowing into the drainage basin main body is drained through a trap attached to the drainage outlet.

The depth of the drainage basin body and the size of the opening are arbitrary, and the shape of the drainage basin body is also arbitrary, but it is usually rectangular in plan view (usually 600 mm to 900 mm in length and 900 mm in width).
150mm) or square (150mm to 200mm on a side). Note that it goes without saying that the dimensions are not limited to this. Examples of the method for covering the flange surface of the drainage basin body with a metal plate include a method using an insert, a method using an adhesive, a method using a screw.

The lid provided on the opening of the drainage basin body may be flat or U-shaped in cross section. A step part is formed on the side wall of the drainage basin body on which the supporting legs of the lid having a substantially U-shaped cross section are placed, the lid is inserted into the drainage basin body by being dropped, and the supporting legs are spanned over the stepped part. In this case, covering the stepped portion with a metal plate can prevent the stepped portion from being worn out or damaged.

[Example] The present invention will be explained in more detail based on the example shown in the drawings.

FIG. 1 is an exploded perspective view of one embodiment, and FIG. 2 is a sectional view of the main part showing a state in which a lid is fitted.

Reference numeral 100 denotes a drainage basin body made of plastic, which is formed into a rectangular parallelepiped of a required length with an open top. Around the opening of the drainage basin body 100,
Flange 1 that is almost flush with the floor of the bathroom washing area
10 are formed. Furthermore, a step portion 104 is formed on the side wall of the drainage basin body 100 on which a supporting leg of a lid having a substantially U-shaped cross section is placed. Then, the lid 20 extends from the upper inner surface of the drainage basin main body 100 to the surface of the flange 110 to the bent portion 112 of the outer edge of the flange 110.
It is covered with a stainless steel covering plate 150 of substantially the same color as 0. In this embodiment, the cover plate 150 is bonded to the drainage basin body 100 by an insert method.

A lid 200 is attached to the drainage basin body 100.
It is inserted into the 00. Lid 2
00 is formed by bending a stainless steel plate into a U-shape, and support legs 21 are formed on both sides at a height such that the surface of the lid 200 becomes approximately flush with the flange 110 when fitted into the drainage basin main body 100. , the supporting leg 21 is placed on the stepped portion 104. A required number of drainage holes 22 are formed in the lid 200, and the drainage from the floor of the washing area rapidly flows into the drainage basin body 100.

In the case of the lid 200 of this embodiment, both sides are bent to increase the strength, and since the load is supported by the supporting legs 21, the lid 200 will not deform even if a person rides on the lid and the load is applied. Moreover, since it is inserted into the drainage basin main body 100 in a state where it is dropped, it will not be removed or deformed. Note that a finger hook 23 is formed on the longitudinal edge so that it can be easily removed from the drainage basin main body 100.

The bottom plate 101 of the drainage basin body 100 is sloped from one side to the other in the length direction, and a drain port 102 to which the trap 1 is attached is formed at the sloped end, and the trap 1 is attached to the drain port 102. Ru.

[Function] To explain the function of this embodiment, the trap 1 is attached to the drain port 102 and buried in the floor of the washing area, and the floor of the washing area is sloped toward the drainage basin. In addition, a lid 200 is attached to the drainage basin main body 100.
Insert it into the 0 position.

The hot water used to wash the body flows down onto the washing area floor, but the waste water on the washing area floor quickly flows into the drainage basin main body 100, so that there is no stagnation of drainage on the washing area floor.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and many modifications can be made within the scope of the claims of the utility model registration.

[Effect of the idea] The present invention produces the following effects.

The main body of the drainage basin is molded from synthetic resin, so it is not only resistant to rust, but also can be molded into any shape.

The flange surface is covered with a metal plate, so even if mortar or concrete adheres to the flange surface during burying, it is easy to remove, leaving no marks and looking clean.

When the lid and the metal plate are made of metal plates such as stainless steel plates of substantially the same color, the flange surface and the lid have a sense of unity, and there is also a sense of unity in design.

The upper part of the drainage basin body will be reinforced with a metal plate, increasing its strength.

When the synthetic resin hardens, it shrinks and it may become impossible to insert the lid, but in the case of the insert method, the specified dimensions can be secured with a metal plate, so dimensional errors do not occur.
