Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a drain outlet cover mounting structure in which the lower end of the drain outlet cover is placed on a shelf provided on the inner circumferential wall of the drain outlet portion of a bathroom unit.

[Background Art] Conventionally, as shown in FIG. 3, a cap-shaped drain cover 6 is fitted into the drain port 2 of the bathroom unit 1. Notches 13 must be formed locally at the lower end of the outlet cover 6, and in particular, in order to improve foam removal, the cutouts 13 must be formed at the upper end of the inner circumferential wall 3 of the drain outlet 2 and at the sides of the drain outlet cover 6. A large space S must be provided between the drain cover 6 and the upper end, and although this space S facilitates removal of the drain cover 6, there is a problem in that toes may get caught. In addition, since a water gradient is formed on the bottom wall 9 around the trap 10 in order to improve drainage, the water gradient between the top surface 7 of the drain cover 6 and the floor surface 8 of the bathroom unit 1 cannot be made uniform. Water and foam removal became even worse, and there were also design problems.

[Purpose of the invention] The present invention was made in view of the above circumstances, and its purpose is to drain water and bubbles without forming a notch at the lower end of the drain cover as in the past. Even if you increase the space between the upper edge of the side of the drain outlet cover and the upper edge of the inner wall of the drain outlet, your toes will not get caught in this space. You can easily remove the drain cover using the finger hook.
Moreover, the water gradient of the upper surface of the drain cover and the floor surface of the bathroom unit are made to match and flush, thereby further improving drainage of water and foam, and making the design more streamlined.

[Structure of the invention] The mounting structure of the drain cover of the bathroom unit of the invention includes a plurality of shelf parts 4 which are spaced apart from each other on the inner peripheral wall 3 of the drain part 2 which is recessed in the bathroom unit 1. A contact part 5 is formed on the shelf part 4, a cap-shaped drain cover 6 is fitted into the drain part 2, the lower end is placed on the shelf part 4 of the drain part 2, and the side part is placed on the drain part 2. This structure is arranged close to the abutting portion 5, and the above object can be achieved with this structure. That is, by placing the lower end of the drain outlet cover 6 on the shelf 4 of the drain outlet part 2, water and bubbles can be drained easily without having to form a notch in the lower end of the drain outlet cover as in the conventional case. Moreover, by changing the height of the shelf section 4, the water slopes of the upper surface 7 of the drain cover 6 and the floor surface 8 of the bathroom unit 1 can be made to match and be flush, which only further improves the drainage of water and foam. In addition, since the side part of the drain outlet cover 1 is placed close to the contact part 5 of the drain outlet part 2,
Even if the space S between the upper end of the side part of the drain outlet cover 1 and the upper end of the inner circumferential wall of the drain outlet part 2 is increased, the toes will not be caught in this space S, and the fingers will not be able to use this space S. The drain cover 6 can be easily removed by hooking it.

The present invention will be described below based on embodiments shown in the accompanying drawings. The bathroom unit 1 is made of FRP, and has a trapezoidal drain port 2 in a corner portion. A trap 10 is attached to the bottom wall 9 of the drain port 2. A plurality of shelves 4 are provided at intervals on the inner circumferential wall 3 of the drain port 2. Shelf portion 4 of inner peripheral wall 3
A contact portion 5 is formed on each of the upper portions. Top surface 7
A cap-shaped drain cover 5 having a drain hole 12 is fitted into the drain port 2, and its lower end is placed on the shelf 3 of the drain port 2, and the side portion is placed close to the contact portion 4 of the drain port 2. One side portion is brought into contact with the abutting portion 4. In this case, the height of the shelf 4 is made smaller toward the side wall 11 of the bathroom unit 1 so that the water gradient of the upper surface 7 of the drain cover 6 matches the water gradient of the floor surface 8 of the bathroom unit 1, and the upper surface 7 and the floor Surface 8 is flush. In addition, the thickness of the contact part 5 is changed, and the thickness of the contact part 5 on the side wall 11 side of the bathroom unit 1 is increased, and the upper end of the side part of the drain outlet cover 1 and the inner circumferential wall of the drain outlet part 2 in this part are changed. The space S between the drain port cover 6 and the upper end is made large so that the drain cover 6 can be easily removed using this space S as a fingerhold.

[Effects of the invention] In the present invention, by placing the lower end of the drain cover on the shelf of the drain outlet, there is no need to form a notch at the lower end of the drain cover as in the conventional case. It drains water and bubbles well, and by changing the height of the shelf on which the bottom end of the drain cover is placed, the water slope between the top surface of the drain cover and the floor of the bathroom unit can be matched. It can be made flush, which not only improves water drainage and foam removal, but also allows for a cleaner design, and the side part of the drain cover is placed close to the contact part of the drain outlet. Therefore, even if you enlarge the space between the upper end of the side of the drain outlet cover and the upper end of the inner wall of the drain outlet, your toes will not get caught in this space, and you can use this space to catch your fingers. The drain cover can be easily removed.
