Description

[Detailed Description of the Invention] The present invention relates to a water storage tank cover that closes the upper opening of the water storage tank in a flush toilet.

Normally, the water storage tank of a flush toilet is installed at the top of the wall as a spare space, but the water in the tank evaporates, causing moisture to build up on the ceiling and walls near the tank, which can cause damage. It was huge.

Furthermore, in public toilets at stations, schools, etc., there are many people who throw trash such as paper and cigarette butts into the water storage tank as a prank, and there is a possibility of obstructions such as clogging of the tank outlet. .

Therefore, if the top surface of the tank is closed with a flat plate-shaped cover, problems such as clogging of the outlet due to debris can be prevented, but there is a drawback that debris accumulates on the top surface of the cover, and water droplets may condense on the top surface of the cover. As mentioned above, the evaporation also causes damage to the ceiling and walls.

However, recent public toilet water storage tanks are equipped with a drainage timing control device that protrudes above the top of the tank to drain water at an appropriate flow rate at predetermined time intervals, and an integrated cover like this is installed. This was usually difficult.

In view of the above-mentioned problems, the present invention aims to prevent the accumulation of debris and damage caused by moisture to the ceiling and walls near the water storage tank. An integrated cover that closes an upper opening of a water storage tank, wherein at least both side walls and the front wall are sloped walls that slope downward, and a groove is provided along the lower edge of each of the sloped walls. A drain port is provided to communicate between the groove and the inside of the tank.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In Figs. 1 to 4, 1 is a water storage tank installed at the upper part of the wall surface, and a drain pipe provided at the bottom of this tank 1. 2, the water is drained into multiple or single toilet bowls.

A cover 5 is placed on the so-called rectangular upper outer circumferential edge 3 of the tank 1 so as to close the upper opening 4 thereof.

The cover unit 5 is integrally formed with FRP in a so-called mountain shape, and the cover unit 5 is placed on the wall side of the outer peripheral edge 3 and has a trapezoidal shape and a back wall 6 that are vertically formed. , an inclined upper wall 7 which extends downwardly in the front from the upper end of the back wall 6; an inclined front wall 8 which extends downwardly in the front from the front end of the upper wall 7; A pair of inclined side walls 9, 9 extend downward from both ends of the wall 7, and along the lower edges of the front wall 8 and both side walls 9, 9, the outside of the tank 1 is provided. Placing parts 10 that come into contact with the upper surface of the peripheral edge part 3 are formed to extend outward in a continuous manner, and a retaining part 11 extending downward from the outer edge of the placing part 10 is connected to the outer peripheral edge. It engages with the outside of part 3.

Further, a so-called dogleg-shaped stopper member 12 is fixed to the back side of the lower center portion of the front wall 8 with adhesive or the like, and as shown in FIG. It is said that it is possible to engage with the inside of the

The front wall 8 and both side walls 9, 9 are placed on the upper surface of the mounting portion 10.
A protruding portion 13 is provided to surround the front wall 8 and both side walls 9, and a concave groove portion 14 is formed along the lower edge of the front wall 8 and both side walls 9, 9.

A plurality of circular drain ports 15 communicating with the inside of the tank 1 are provided in the groove 14 at appropriate intervals.

Further, as shown in FIG. 5, the drain port 15 is expanded to a larger diameter at the lower end.

Incidentally, as shown in FIG. 6, an annular protrusion 17 may be formed at the lower end edge of the drain port 15.

Further, a ventilation portion 16 for preventing negative pressure during drainage is separately attached and formed on each of the side walls 9, 9.

The embodiment of the present invention is constructed as described above, and the movement of the integrated cover 5 in the lateral direction P with respect to the tank 1 is regulated by the retaining parts 11 at both ends, and the movement of the integrated cover 5 in the longitudinal direction Q is restricted. Since it is regulated by the stopper member 12 and the engaging portion 11 at the front end, there is no risk of the cover unit 5 being displaced or accidentally falling off.

Furthermore, even if trash such as paper or cigarette butts is thrown onto the top surface of the cover 5, the top wall 7, front wall 8, and both side walls 9, 9 are all slanted walls.
Dust particles can be prevented from sliding or rolling down along the base walls 7, 8, 9, 9, and from accumulating on the upper surface of the cover unit 5.

Furthermore, water droplets that have condensed on the outer surface of the cover integral 5, for example,
As shown in the figure, the water flows down along the inclined base walls 7, 8, 9, 9, collects in the groove 14, and is automatically stored in the tank 1 through the drain port 15.

Therefore, it is possible to prevent the ceiling and wall surfaces from becoming damp due to evaporation of condensation, and damage caused by moisture can be prevented.

Further, since the lower end of the drain port 15 is formed to have a larger diameter, water drains easily.

Furthermore, by forming the annular protrusion 17, water drainage becomes even better.

Furthermore, since the cover unit 5 has an upwardly protruding chevron-shaped configuration, even if the tank 1 is equipped with a drainage timing control device, it is attached to the container.

In the embodiments described above, the drain port 15 is shown as being circular, but it may be in an elongated shape.

Further, like the front wall 8 and both side walls 9, 9, the back wall 6 is also an inclined wall, and a groove 14 is formed over the entire circumference of the flat edge of the base wall 6, 8, 9.9.
Alternatively, the base walls 6, 7, 8, 9.9 may be formed into a so-called dome shape in which the base walls 6, 7, 8, 9.9 are continuously inclined. Since each wall is an inclined wall that expands downward, the earthen wall portion is also narrow, and dirt can be prevented from accumulating on the upper surface of the cover.

In addition, a groove is provided at the lower edge of the sloped wall, and a drain port is provided that communicates the groove with the inside of the water storage tank, so that water droplets condensed on the outer surface of the cover flow along the sloped wall.
It is automatically stored in the tank via the drain port.

Therefore, there is an advantage that damage to the ceiling and wall surfaces due to moisture can be prevented.
