Description

[Detailed Description of the Invention] "Purpose of the Invention" (Field of Industrial Application) The present invention relates to a cleaning tank such as a low tank or a high tank formed of a resin material.

(Conventional cleaning tank) Construction costs for bathrooms, toilet rooms, etc. are reduced by unitizing them. A typical bathroom unit is shown in Figure 4. Recently, in addition to the above-mentioned reduction in construction costs, efforts have been made to thoroughly reduce the manufacturing costs of each piece of equipment installed in the room, and to supply the unit room as a whole to users at a low price. Tend. Toilet bowls were the first to be targeted in order to reduce the cost of equipment.
It was the cleaning tank 2 attached to the.

Conventionally, measures have been taken to change the material for forming the cleaning tank 2 from ceramic, which is expensive, to resin, which is low cost. Furthermore, the tank body 2b
The outer shell of the car was made thinner to reduce the amount of resin used.

(Problems to be Solved by the Invention) When the cleaning tank 2 is full of water, the outer shell plate forming the tank body 2b bulges and deforms due to the water storage pressure. That is, the tank body 2b
The lid body 2a covered with the tank body 2b was forcibly fitted into the tank body 2b, and could not be removed.
Therefore, when loading cleaning aids, fragrances, etc. into the cleaning tank 2, or when performing maintenance on equipment inside the tank, all of the water stored in the cleaning tank 2 must be drained one by one. It didn't happen. Lid body 2a without draining the stored water.
Forcibly removing the lid 2a and the tank body 2b will not only lead to damage, but even if it can be removed, the lid 2a will not be able to cover the tank body 2b again, and in the end. , drainage work was required.

The present invention was developed in view of the above-mentioned circumstances, and by making it possible to attach and detach the lid to the tank body even when the tank is full of water, it is possible to load cleaning aids, fragrances, etc. The purpose of the present invention is to provide a new resin cleaning tank (hereinafter referred to as the "proposed tank") that facilitates maintenance and prevents damage to the lid and tank body.

``Structure of the invention'' (Means for solving the problem) The gist of the proposed tank is that the tank is made of resin and consists of a tank body with an opening at the top and a lid body that covers the opening of the tank body. In the tank, the outer surface of the front plate and side plate of the tank body is formed to be a smooth surface without any protrusion, the front plate of the tank body is formed thick, and the outer surface of the rear plate of the tank body is A horizontal beam rib is protruded from the upper part along the opening edge, and vertical side ribs which are flush with the side plate and extend downward from the beam rib are protruded from both sides. An appropriate number of medium ribs extending downward from the beam rib are protruded between the ribs, and the beam rib, side rib, and medium rib are integrally formed, and the protruding height of each is set to be equal. It is.

(Function) The present invention mainly relates to the reinforcing structure of the tank body, and the front plate, the back plate, and the upper opening edge are provided with respective reinforcing structures. That is, the front plate is made relatively thick and reinforced by adding a reinforcing layer. The back plate is reinforced by an appropriate number of middle ribs protruding along the longitudinal direction and side ribs extending from both side plates. Further, the upper opening edge is reinforced by providing beam ribs projecting laterally above the upper ends of the middle ribs and side ribs in the upper part of the back plate. In short, the tank of this invention has the unique reinforcing effect of the reinforcing layer on the front plate, the middle ribs and side ribs on the back plate, and the beam ribs on the upper opening edge, and the mutual rigidity of each acts synergistically to form the tank body. This structure prevents the tank body from being swollen and deformed to the extent that it becomes impossible to attach or detach the lid due to an external force equivalent to the full water storage pressure.

(Example) The present invention will be described below based on drawings showing examples thereof.

1 to 3 show the tank of the present invention, in which FIG. 1 is an exploded perspective view of the lid 3 and tank body 4, FIG. 2 is a rear perspective view of the tank body 4, and FIG. 3 is a plan sectional view showing the tank body 4 cut along the plane A-B-C-D in FIG. 1.

The proposed tank has a front plate 4a as shown in FIG.
is formed relatively thick, a middle rib 5 is provided at the center of the back plate 4b, and side ribs 6 are provided on both sides of the back plate 4b flush with the side plates 4c. As shown, the back plate 4 at the upper opening edge 4d
A feature is that a beam rib 7 is provided above b.

The front plate 4a is connected to the back plate 4 as shown in FIG.
b, is relatively thick compared to other outer shell plates such as the side plate 4c. This thick portion is a reinforcing layer. The reason why the reinforcing layer is formed as described above without providing reinforcing ribs or the like in the front plate 4a is as follows. Generally, when projections such as reinforcing ribs are integrally formed on a resin plate, "sink marks" occur on the back side due to curing and shrinkage of the resin material, and this is an inevitable phenomenon. This is because the "sink" has the drawback of deteriorating the appearance of the front plate 4a and giving an impression of poor quality as a cleaning tank. In this example,
The thickness of the outer shell plates such as back plate 4b and side plate 4c is 2.5mm.
In contrast to the front panel 4a with a reinforcing layer added.
The wall thickness was set to 5.0mm.

As shown in FIG. 2, the middle rib 5 is provided to protrude in the vertical direction over substantially the entire height of the back plate 4b. The direction in which the middle ribs 5 protrude is toward the mounting wall surface (not shown) of a building frame or the like facing the back plate 4b, and not toward the inside of the tank body 4. Therefore, the mounting space for a ball tap, a float valve, etc. (not shown) is not limited inside the tank body 4. Furthermore, the ease of cleaning the inner surface of the tank is not hindered. In this embodiment, three middle ribs 5 are provided, and the mutual spacing between the middle ribs 5, 5, 5 is made equal. In addition, a plurality of small ribs 8, 8, . . . are further provided protrudingly provided at intervals between the respective medium ribs 5, 5, 5, to enhance reinforcement. Note that reference numerals 9 and 9 in the figure are hanger portions for engagement with hook fittings (not shown) fixed in advance to the mounting wall surface (not shown) of the building frame or the like.

As shown in FIG. 3, the side ribs 6 are similar to the middle ribs 5.
It protrudes in the same direction as the side plate 4c and extends toward the mounting wall surface of the building frame or the like, flush with the side plate 4c.
That is, the side rib 6 is integrally continuous with the side plate 4c, and the connecting portion between the two is not substantially exposed. In addition, the side ribs 6 are visible from the outermost surfaces 5a, 5a of the middle ribs 5 from a person who views the gap between the back plate 4b and the mounting wall from the side. It also acts as a visual blocker. In this embodiment, the protruding ends of the side ribs 6 are bent toward the center of the back plate 4b and then connected to the back plate 4b in an inclined manner. Therefore, the section modulus of the corner portion between the side plate 4c and the back plate 4b is increased more than the extension of the side ribs 6, and a strong reinforcing effect is achieved.

As shown in FIG. 2, the beam rib 7 is provided to protrude in the lateral direction over substantially the entire width of the back plate 4b at the upper part of the back plate 4b of the upper opening edge 4d. The beam rib 7 is connected to all upper ends of the middle rib 5 and the side ribs 6, so that the longitudinal reinforcement by each rib has rigidity. In addition, in the tank of the present invention, if the beam ribs 7, middle ribs 5, and side ribs 6 are not integrally connected, stress concentration may occur in the unconnected parts, so another reinforcement structure must be considered. There are serious concerns.

(Study of Alternative Embodiments) The tank of the present invention is not limited to being installed in a unit room, but can be widely used as a cleaning tank attached to a toilet bowl. Further, the tank of the present invention is not limited to a suspended type as in the above embodiment, but may be of a stationary type. Furthermore, the number of protruding central ribs 5 and the necessity of small ribs 8 are increased or decreased as appropriate depending on the width dimension and capacity of the tank body 4. It is also conceivable that only one rib 5 is used.
Further, the beam rib 7 is not limited to being provided integrally with the upper opening edge 4d, but may be such that its horizontal height is slightly shifted downward. In this way, the configuration and shape of the tank of the present invention can be changed as appropriate depending on the embodiment.

"Effect of the invention" As is clear from the above explanation, according to the resin cleaning tank according to the invention, the tank body has horizontal beam ribs integrally formed with the vertical side ribs and middle ribs. Therefore, at least deformation of the opening is prevented when cleaning water is stored.
Therefore, the outer shell plates such as the front plate, rear plate, side plates, etc. will never swell or deform even if they are subjected to an external force equivalent to the full water storage pressure with the lid removed. In other words, the lid can be attached and detached without any difficulty regardless of whether or not water is stored, and it is necessary to load cleaning aids, fragrances, etc. into the tank body, maintain the equipment inside the tank, etc. becomes easy. Of course, when removing or covering the lid, the lid and the tank body will not be damaged. Furthermore, the ribs that protrude from the surface of the tank body are provided only on the back side, and the protrusion heights are made the same, so the protrusion on the front and side sides can be reduced by installing the ribs on the back side close to the mounting wall. Since only a smooth surface with no parts is visible on the surface, the appearance is very good. Even if the lid is removed from the tank body, anyone looking at the top opening of the tank body will only be able to see the inner surface of the beam ribs at the top of the back plate, and the upper ends of the middle ribs and side ribs will be visually blocked. Since there,
Since the tank body is made of resin material, it does not give an inferior feeling. Furthermore, the inner surface of the beam ribs prevents water droplets adhering to the back surface of the lid from dripping into the gap between the tank body and the mounting wall surface of the building frame, etc., so pests, mold, etc. can occur in the gap. It can also be prevented. Needless to say, even if various reinforcement structures such as those mentioned above are added,
The amount of resin material used to form the proposed tank is:
It has many excellent advantages, such as being within a range that satisfies the reduction in manufacturing cost of the cleaning tank and having no fear of impairing the appearance of the tank of the present invention.
