Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a drainage basin for the floor of a bathroom washing area, and particularly to a drainage basin for the floor of a bathroom washing area in which the lid is difficult to remove from the basin.

[Prior art and its problems] Conventionally, a so-called circular plate, which is a disk with a required number of holes, has been installed and used at the drain outlet of a bathroom washing area in order to separate wastewater from hair and other debris. was.
However, because insects and bad odors come up from sewage, in recent years water-sealed traps with insect- and odor-proof measures have been used, but because these traps are water-sealed, drainage efficiency is poor. However, if the amount of wastewater is a little large, the drainage will stop immediately, and the area around the drain outlet will be overflowing, making it unclean.

[Purpose of the invention] Therefore, the first purpose of the invention is to prevent wastewater from accumulating on the washing area floor of a bathroom even if a trap with poor drainage efficiency is used.

In addition, when taking a bath, people are naked and the floor is wet and slippery, making it easy to get injured, so special attention must be paid to safety.

Therefore, the second purpose of the present invention is to make it difficult to remove the lid from the drainage basin so that it is safe even when used on the bathroom floor.

[Structure of the invention] The structure of the invention taken to solve the above problems is as follows.

The present invention includes a drainage basin body that is buried in the bathroom floor and a lid that fits into the drainage basin body.The drainage basin body is made of a metal plate or plastic and has an opening at the top to allow wastewater from the bathroom bathroom floor to flow in. A flange is formed outwardly around the periphery of the opening, and the drain is provided with a water-sealing trap, the lid is made of sheet metal or plastic, and the inlet has a flange facing outward. A supporting leg plate is provided facing downward from the side edge of the cover plate provided with the support plate, and the supporting leg plate is set to support the upper surface of the cover plate at approximately the same height as the upper surface of the flange. This drainage basin for a bathroom washing floor has a cutout formed on the side edge in the horizontal direction to prevent the pulling-up side edge from coming into contact with the inner wall of the drainage basin body when one end of the fitted lid is pulled up.

The number, size, and shape of the inflow ports provided in the lid plate are not particularly limited as long as they allow drainage from the bathroom floor to flow into the drainage basin body. The cutout is formed on one or both of the side edges in the height direction of the supporting leg plate, and its shape is not limited as long as it can prevent the lifting side edge from coming into contact with the inner wall of the drainage basin body when one end of the lid is pulled up.

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

FIG. 1 shows one embodiment of the present invention, and is an exploded oblique view of the lid and the catch basin body, FIG. 2 is a schematic explanatory diagram showing how to open the lid fitted into the catch basin body, and FIG. 3 is a perspective view showing the catch basin in the installed state.

The drainage basin main body 1 is made of a metal plate, and is formed in the shape of a rectangular parallelepiped with a required length and an opening 10 at the top. A flange 11 is formed around the opening. The bottom plate 12 of the drainage basin body 1 is sloped from one side to the other in the length direction, and a drain port 13 is formed at the lower end of the slope. Drain port 13
A water-sealing type trap 3 with screws carved around the lower part of the circular perforated plate is inserted into the trap 3, and is fixed with a tightening ring (not shown) across the bottom plate 12.

A lid 2 fitted into the drainage basin main body 1 is made of a metal plate made of the same material as the drainage basin main body 1.

The lid 2 has a lid plate part 20, and supporting leg plates 21 are bent and formed on both sides along the length direction. The height of the supporting leg plate 21 is set so that the upper surface of the cover plate portion 20 is approximately at the same height as the flange 11 surface of the drainage basin body 1. Cutouts 24 are formed on both edges of the support leg plate 21 in the height direction to prevent it from coming into contact with the inner wall of the drainage basin body 1 when one end of the fitted lid 2 is pulled up (see Figure 2). . In addition, the lid plate part 20 has a required number of inlets 22 through which the wastewater from the bathroom washing floor flows into the drainage basin main body 1.
is formed, and finger hooks 23 are provided at both lengthwise ends.
is formed.

In the drainage basin according to this embodiment, the floor plate 12 of the drainage basin body 1 is sloped to allow water to flow easily, so the upper surface of the drainage basin body 1 can be installed parallel to the floor of the washing area, and construction work is easy. Easy to do. Moreover, since the inner surface of the drainage basin body 1 is smooth, it is easy to clean.

(Function) As shown in FIG. 3, the drainage basin main body 1 is buried in the bathroom floor with the flange 11 and the bathroom floor flush with each other, and is used by fitting the lid 2 through the opening 10.

Hair and the like that flowed in from the inlet 22 accumulate in the drainage basin main body 1, so it is necessary to open the lid 2 and clean it from time to time. There is a method of opening the lid 2 by raising the entire lid 2 horizontally. However, if the lid 2 is heavy, force is required to pull it up.

Therefore, as shown in FIG. 2, inserting your finger into the finger hook 23 and pulling up one end of the lid 2 makes it easier to remove the lid. In this case, a cutout 2 is provided on the side edge of the support leg plate 21 in the height direction to prevent it from coming into contact with the inner wall of the drainage basin body 1.
4, the lid 2 can be pulled up smoothly.

It should be noted that the present invention is not limited to the illustrated embodiment, and many modifications can be made within the scope of the claims for utility model registration, such as making the drainage basin body square in plan view.

[Effects of the invention] (a) The main body and lid of the drainage basin are made of metal plate or plastic. Due to the nature of the material,
It is superior to mortar in terms of ease of manufacture, transportation and construction, and aesthetic appearance, and has greater commercial value than mortar.

(b) A flange is provided on the periphery of the opening of the drainage basin body facing outward. Therefore, when installing the drainage basin body, it is easy to install the bathroom floor surface and the drainage basin body flush with each other.

Furthermore, even if the edge of the lid accidentally applies an impact to the edge of the opening when the lid is inserted, the tile does not come into direct contact with the tile, so damage to the tile can be prevented.

(c) The main body of the drainage basin has an opening through which the wastewater from the bathroom washroom floor flows in, and the drainage outlet is equipped with a water-seal trap. Therefore, in a washing area with a buried drainage basin, the waste water on the floor flows once into the drainage basin body, and even if a water seal type trap with poor drainage efficiency is used, the drainage does not accumulate on the washing area floor and does not feel unclean.

Also, it is equipped with a water-sealing trap, so insects will not be able to smell the bad smell.

(d) supporting leg plates are provided facing downward from the side edges of the cover plate, and the supporting leg plates are set to support the upper surface of the cover plate at approximately the same height as the upper surface of the flange;
The lid is attached by fitting the lid plate part and the support leg plate into the main body of the drainage basin. Therefore, there is no step formed between the drainage basin main body and the lid plate that can cause tripping.

Further, even if force is applied to the lid from an oblique direction, the supporting leg plate prevents the lid from being removed from the drainage basin body, and injuries caused by the removal of the lid do not occur.

(e) A cutout is formed on the side edge in the height direction of the supporting leg plate to prevent the lid from coming into contact with the inner wall of the drainage basin body and preventing the lid from being pulled up when one end of the fitted lid is pulled up. can be pulled up smoothly.

Further, by forming the supporting leg plate, the strength of the lid against bending due to a load from above is improved.
