DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a civil engineering construction site, a park,
The present invention relates to a toilet tub of a temporary toilet temporarily installed at a place where an event is held.

[0002]

2. Description of the Related Art FIG. 3 shows a simplified flush type temporary toilet which has been increasing in demand recently. The temporary toilet includes a toilet tub 1 serving as a base and a step pedestal 2 installed on the toilet tub 1. A toilet bowl 3 installed in the center of the step 2, a side wall 4 fixed on the toilet tank and surrounding the step 2 (a left side wall and a front door are omitted), a roof 5 installed on the side wall 4, and the like. Consisting of
Further, a pump (not shown) is provided in the platform 2, and when the lever 6 is depressed, water in a water tank (not shown) flows into the toilet bowl 3 by the action of the pump, and is washed. It is to be noted that a water tank fixed to the inside of the side wall 4, formed integrally with the side wall 4, or installed in the step 2 is conventionally known.

Conventionally, the toilet tub 1 is made of FRP (fiber reinforced polyester) or the like. At present, however, an integral structure made of polyethylene by blow molding is used. As shown in FIGS. 3 and 4, a step 7 is formed by partially welding upper and lower walls on the front side of the toilet tub 1 by blow molding, and a hole 8 connected to the toilet bowl 3 is formed in the upper wall 1 a of the toilet tub. Is formed, and a suction port 9 and a drain port 10 are formed on the rear side of the toilet tub. The wall of the toilet tub 1 is a single wall, and has a large wall thickness to cover insufficient rigidity. The upper wall 1a and the side wall 1b are recessed inward at a plurality of locations, and reinforcing ribs are provided there. 11 (11a, 11
b) is formed, and the ribs 12 are formed in the step 7.

In the toilet tub 1, since a large number of ribs 11 protrude inward, dirt is caught on the ribs 11 during pumping or washing, and remains in the toilet tub forever. There is. Also,
The toilet tub 1 is manufactured by blow molding in a mold (split mold) constituting a cavity corresponding to the outer shape of the toilet tub 1, and its outer surface is in contact with the mold and has a smooth finish. On the other hand, since the inner surface does not contact the mold, small irregularities are distributed over the entire surface. As with the ribs 11, dirt is caught on these irregularities, making it difficult to clean the inside of the toilet tub.

Further, since the toilet tub 1 has a single-wall structure, if it is damaged, sewage may leak, or its heat insulation may be inferior, so that the internal temperature rises in summer and odor becomes a problem. When the inside temperature drops through the outside (installation ground) and the inside and outside of the toilet tank freezes, the bottom wall and the side wall of the toilet tank 1 are caught by the pressure of the ice inside and outside, and the toilet tank is damaged or damaged. In many cases, the bottom of the toilet tub 1 cannot be moved, and if it is forcibly lifted, it may be damaged. This is prevented by not directly reaching the ground.

On the other hand, in the case of a simple flush type temporary toilet, a water tank is installed. However, in the conventional type, the position of the center of gravity of the entire toilet tank 1 becomes high when the toilet tank 1 is empty, and especially when the water tank is full, the center of gravity becomes water. Moving to the tank side, the balance was even worse. In some cases, the toilet tilted or fell. Further, when the water tank is fixed to the inside of the side wall 4, there is also a problem that if the capacity of the water tank is increased, the space in the room becomes narrow.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the above-mentioned conventional blow stool, and it is easy to remove dirt and clean the inside thereof, and it has high rigidity and light weight. In addition, it is an object of the present invention to obtain a toilet tub that is less likely to leak waste and has a high heat insulating property, and further to obtain a toilet tub suitable for a simple flush type temporary toilet tub.

[0008]

SUMMARY OF THE INVENTION The present invention relates to a toilet bowl for temporary toilet, which is obtained by blow-molding plastic in a mold, and has a recess for containing waste. It is characterized by comprising a toilet tub body having a hollow double-walled structure and a lid separate from the toilet tub body covering a recess of the toilet tub body. In the above-mentioned temporary toilet stool, the inside of the double wall structure of the toilet tub body can be used as a water tank, and in that case, it is suitable as a simple flush type temporary toilet stool.

[0009]

[Function] Since the toilet tub body of the temporary toilet has a double wall structure, the tub body is reinforced by forming a rib on the bottom wall side without forming a rib on the upper wall side in a recess for storing waste. It is possible to obtain a toilet tub without protrusions of ribs that hinder cleaning in the recess, and at the same time, the ribs formed on the bottom wall side may be freely formed because they do not hinder the cleaning of the toilet tub, It is possible to obtain a toilet tank that is lightweight and highly rigid. In addition, since the outer surface of the toilet tub comes in contact with the mold, the surface of the recess for storing the dirt has a smooth finish, and the dirt is not caught on this surface.

[0010] The temporary toilet tub has a double wall structure, so that there is no leakage of dirt even when one of the bottom wall and the upper wall is damaged, and there is a space between the double walls to provide heat insulation. The temperature rise and odor generation in summer are suppressed, and freezing in winter is also suppressed. Even if the inside and outside of the toilet tank are frozen in winter, if there is a space between them, both walls are deformed by the pressure of the ice and the pressure can be released, and the toilet tank can be moved without being damaged.

The toilet tub body has a space between the double walls, and this space can be used as a water tank to provide a simple flush type temporary toilet tub. In this toilet tank, when the recess is empty, the water tank is usually full, and when the water in the water tank is reduced, dirt accumulates in the recess, so that the center of gravity is always low and stable. Also, the space for the water tank can be arranged in a well-balanced manner around the toilet tank body,
This also increases the stability of the toilet. Even for temporary toilets that are not simple flush type, the space between the double walls is
It is advisable to add water to this and to make it highly stable. Other configurations and operations of the present invention will be described in the following embodiments.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The toilet tub shown in FIG.
1, each of which is a hollow double-walled structure obtained by blow-molding a parison in a split mold forming a cavity corresponding to each outer shape. Toilet tank body 20
In the figure, the upper wall 20a is largely recessed to form a recess 22 for accommodating dirt, and the bottom of the recess 22 has a downward slope toward the rear. The bottom wall 20b has a plurality of top walls 20
a at the top of the upper wall 2 at this recessed point.
0a and a bottom wall 20b and an upper wall 20a.
Are formed. Toilet tank body 20
A step 24 is formed on the front side of the rib 25, and a rib 25 extending from the bottom wall 20b to the upper wall 20a also in the step 24.
Is formed. On the other hand, the lid body 21 has an upper wall 21a that is substantially flat, and a lower wall 21b is recessed toward the upper wall 21a at a plurality of locations. Rib 26 connecting wall 21a
Is formed, and is finished in a shape that covers the recess 22 of the toilet tub body 20 as a whole. Reference numerals 27 and 28 denote lift claw grooves, and reference numeral 29 denotes a pumping port.

In the toilet tank body 20, the ribs do not protrude inside the recess 22 for accommodating filth, and the inside of the recess 22 comes into contact with the mold at the time of blow molding. This makes it difficult for dirt to remain on the floor during sampling or cleaning, and is easy to clean. Furthermore, since the bottom of the recess 22 has a downward slope toward the rear (the conventional toilet 1 does not have a slope because it has a single wall), dirt is drawn toward the pumping port 29 (rear). Naturally, the dirt is less likely to remain inside, and if the lid 21 is removed, the recess 22 is completely opened, so that it is possible to clean the dirt with zero remaining.

The rib 23 formed on the bottom wall 20b has a recess 22
Since it does not protrude into the inside of the toilet, it can be formed freely considering only the reinforcing surface without worrying about the flow of the waste, and a lightweight (thin-walled) highly rigid toilet tub can be obtained. In step 24, the rib 25 extending from the bottom wall 20b to the upper wall 20a is formed.
No conventionally formed concave groove is formed on the upper surface of 4, and sufficient reinforcement can be achieved. Heretofore, since a concave groove by the rib 12 was formed on the upper surface of the step 7, the concave groove was clogged with mud and the like, and the cleaning was troublesome. Needless to say, ribs similar to the ribs 23 and 25 can be formed and reinforced on the side surface and the rear side of the toilet tub body 20 as appropriate.

Since the toilet tank body 20 has a double wall structure, if only one of the top wall 20a or the bottom wall 20b is damaged, no leakage of filth will occur, and it is safe to move the toilet tank by dragging on the ground. There is often (it is often dragged on the ground when moving a temporary toilet, but in the past the bottom of the single-wall toilet tub was damaged and filth could leak out). Further, in the conventional toilet tub 1, waste may sometimes leak from the drain outlet 10. However, in this toilet tub, the waste naturally flows to the side of the pumping port 29 as described above, and the lid 21 is removed. Since cleaning can be performed, a drain port is not required, and there is no need to worry about leakage from the drain port which often occurs in the past. Further, the toilet tank is composed of a toilet tank body 20 and a lid 2.
Since both of them have a hollow double wall structure, they have good heat insulating properties.

In the embodiment shown in FIG. 2, the interior of the double wall structure of the toilet tub body 30 which is almost the same as the toilet tub body 1 of the above embodiment is used as a water tank of a simple flush toilet. The water stored in the pump 3
3 is pumped up and flushed into the toilet 34. Reference numeral 35 denotes a recess for accommodating waste, 36 denotes a cover for covering the recess 35, 37 denotes a step platform, 38 denotes a rear side wall, and 39 denotes a water inlet to a water tank.

[0017]

According to the present invention, it is possible to obtain a toilet tub of a temporary toilet in which filth can be easily collected and the inside thereof can be easily cleaned. In addition, the toilet tub of the present invention can be increased in rigidity even if it is light in weight, does not easily leak dirt, and has high heat insulation, so that generation of odor in summer is suppressed, and it is resistant to freezing. In addition, when the inside of the double wall structure is used as a water tank, the stability of the toilet is increased, and it is suitable as a toilet for a simple flush type temporary toilet.
