Description

  The present invention relates to a drain outlet cover used for a drain outlet of a tank body such as a wash basin, a sink, and a hand-washer.

Conventionally, a tank body such as a wash basin, a sink, a hand-washer or the like has been provided with a drain outlet on the bottom in order to discharge waste water to the sewage side. A conventional example will be described with reference to the drawings.
What was shown in FIG. 5 is the tank body called the wash bowl with which the wash basin which is drainage equipment is equipped, and the eye plate member with which it was equipped.
There is an opening called a drain outlet on the bottom of the tank body, and after the pipe body is connected in the direct downward direction from the opening, odors and pests are prevented from entering the indoor side from the sewage side. It connects to the trap member bent in the shape, and is further connected to the underfloor piping arrange | positioned in the underfloor space via the pipe body from the trap member.
Furthermore, a member having a plurality of slits called a plate member covering the drain port is arranged at the drain port, and the dust in the drainage such as sand, hair, jar and the like is collected.

When using the above-described washstand, if wastewater is generated in the wash bowl, which is a tank body, wastewater mixed with dust is discharged from the drain outlet. After passing through the trap member, the drainage is discharged to the sewage side through the underfloor piping.
Further, when passing through the trap member, the trap member has a shape obtained by bending the tubular body into an S-shape, so that a drainage pool is generated inside the trap member. Since odors and pests from the sewage side cannot exceed this drainage pool, odors and pests from the sewage side can be prevented from entering the indoor side. The drainage that is inside such a trap member and prevents odors and pests from entering the indoor side from the sewage side is called sealed water.

When the drain outlet is covered with a drain outlet cover, the user can shield the situation inside the drain outlet from the user, conceal the dirt and dirt in the drain outlet, and the user feels uncomfortable. I don't have to.
On the other hand, when the eye plate member is arranged at the drain outlet, the dust in the waste water is separated into the eye plate member and the dust can be prevented from flowing into the pipe, so that the occurrence of clogging of the pipe can be suppressed.

In both cases where the drain outlet is provided with a drain outlet cover or a pan head member, the drain outlet cover or the pan head member is arranged so as to be in contact with the drain outlet. A gap portion where the flow of waste water deteriorates occurs. If sand, hair, dust, or the like enters the gap, it becomes difficult to be discharged by drainage, and if left for a long time, it often causes darkening or slime.
Also, if a hard and fine dust such as sand enters the gap between the eye plate member or the drain port cover and the drain port, the sand will bite into the eye plate member or the drain port cover when lifting the eye plate member or the drain port cover. In some cases, it was impossible to lift it up, or if it was lifted forcibly, the washstand, which is a member or tank body, and the drain outlet might be damaged.
Moreover, the drain outlet is normally formed by the member inserted from the surface of the tank body called a drain plug. For this reason, a gap is formed between the bottom of the tank body and the end of the drain plug, and dust has entered the gap to cause slime and darkening.

  The present invention has been made in view of the above-mentioned problems, and the purpose of the treatment is that the dust cover adheres to the drain outlet cover used in the drain outlet of the tank body, blackening or slime occurs, Further, the present invention provides a drain cover that does not get sanded and cannot be lifted or scratched.

And by making the cover body transparent, when drainage flows, the user can see how the drain cover rotates and the rotating wings rotate, making it fun to enjoy like a toy. it can.
(4) In the present invention described in claim 4, by providing the shaft part of the drain outlet cover with the eye plate member for collecting the dust in the waste water, the dust in the waste water is separated into the eye plate member. Since dust can be prevented from flowing into the piping, the occurrence of clogging can be suppressed.
(5) In the present invention according to claim 5, a drain outlet cover having an overall specific gravity close to 1 but larger than 1 is obtained by devising materials and the like. The "total specific gravity" here is the weight of the whole drain outlet cover divided by the volume of the whole drain outlet cover. Even if the specific gravity of each member such as a cone is extremely different from 1, It means that it functions as a member having a specific gravity close to 1 as a whole. As described above, the drain port cover has a specific gravity close to 1 but larger than 1, so that the drain cover has a leg portion near the drain or the drain due to the flow of drainage generated during drainage. As a result, the gap portion is eliminated and dust such as sand and hair can be more easily discharged.
