Description

TECHNICAL FIELD The present invention relates to a vehicle-mounted temporary flush toilet that can be used while placed on a carrier, and a temporary flush toilet system using this vehicle-mounted temporary flush toilet.

Construction sites and event venues that are set up outdoors for a limited time often do not have permanent outdoor toilets around them. Under such circumstances, portable temporary toilets were generally set up. Conventional portable temporary toilets had to be transported to the planned construction site by truck and set up using a crane or the like. In addition, when installing in a different place, it is necessary to load and unload again using a crane or the like, and a large amount of labor is spent on installation and transportation work. In order to deal with such problems, a mobile temporary toilet that can be used while mounted on a vehicle has been proposed.

In Patent Document 1, it can be easily fixed to the bed of a truck, the height can be lowered by lowering the ceiling part during transportation, and it can be used both in a vehicle-mounted state and in a stationary state on the ground. Temporary toilets are proposed. In this temporary toilet, a box-shaped ceiling is configured to be able to move up and down with respect to a box-shaped main body. Since the temporary toilet is equipped with shielding means for blocking the gap between the two, the height of the temporary toilet can be lowered by lowering the ceiling part when it is placed on the bed of a truck and transported. Therefore, during transportation, the height limit is not violated, the wind is not affected, and the driving of the truck is safe. In addition, it can be easily and stably fixed to the bed of the truck without using a fixing rope or the like.

Patent Literature 2 proposes a mobile temporary toilet provided with a bellows-like roof portion that can be expanded and closed. This mobile temporary toilet accommodates a commercially available pump-type simple flush toilet inside.

JP 2004-270427 A JP-A-2005-87380

The temporary toilet proposed in Patent Literature 1 does not disclose whether or not it is a flush type, and does not disclose the arrangement of a storage tank for storing waste. However, from the drawings, etc., it is assumed that it is a non-flush type and that the storage tank is arranged below the toilet bowl. If it were a non-flushing type, the inside would be filled with the odor caused by the waste, and it would not be possible to keep the internal environment in a comfortable state. Also, if the storage tank for storing waste is placed under the toilet bowl, it is necessary to take steps such as rotating the gate provided on the loading platform in order to dispose of the waste.

The temporary toilet proposed in Patent Document 2 is disclosed to be of a simple flushing type, but as in Patent Document 1, it is presumed that a storage tank for storing waste is arranged below the toilet bowl. . Therefore, it is considered that the odor caused by the filth fills the interior to some extent and remains, and it is necessary to take the same procedure as in Patent Document 1 in order to dispose of the filth.

The present invention has been made by focusing on these problems, and incorporates a vehicle-mounted temporary flush toilet and a vehicle-mounted temporary flush toilet that can maintain a comfortable internal environment and facilitate waste disposal. A flush toilet system is provided.

The invention for solving the above-mentioned problems is an in-vehicle temporary flush toilet that can be used while being placed on a transport vehicle, and includes a toilet housing provided with a toilet bowl and a toilet bowl for washing excrement excreted in the toilet bowl. A water storage tank that supplies the washing water, a crushing and pumping device that crushes the washed waste and pumps it to the external space as dirty water, a sewage tank that stores the dirty water pressure-fed to the external space by the crushing pumping device, and a toilet housing. The crushing and pumping device is housed in the housing, and the water storage tank and the sewage tank are mounted on the housing.

According to this configuration, the waste excreted in the toilet bowl is sent to the crushing and pumping device together with the flush water, and is stored as waste water in the waste water tank provided in the external space. does not flow into the interior of the toilet housing. In addition, according to this configuration, the crushing and pumping device is housed in the housing section provided along with the lower end of the toilet housing, and the water storage tank and the sewage tank are placed in the housing section. Efficient use of space can be achieved, and space-saving of the vehicle-mounted temporary flush toilet can be achieved.

Preferably, flush water stored in the water storage tank is supplied to the toilet bowl by operating a pump, and the pump is stored in the storage part.

According to this configuration, since the flush water stored in the water storage tank is supplied to the toilet bowl by operating the pump, it is not necessary to raise the water storage tank to a predetermined height or higher in order to send the flush water to the toilet bowl. . Further, since the pump is housed in the housing, the space of the toilet housing can be utilized more efficiently, and the space of the vehicle-mounted temporary flush toilet can be further reduced.

Preferably, the sewage tank is equipped with an inflow valve for inflowing sewage at an upper end thereof, and an exhaust valve for discharging sewage stored in the sewage tank at a lower end thereof.

According to this configuration, the sewage tank has an inflow valve for inflowing sewage at its upper end and a discharge valve for discharging the sewage stored in the sewage tank at its lower end, so that the discharge valve is released. This allows almost all the stored sewage to be discharged from the storage tank. In addition, since the discharge valve is positioned above the accommodation portion of the vehicle-mounted temporary toilet placed on the carrier, a high water head can be ensured. Under certain conditions, this eliminates the need for a pump or the like to discharge the accumulated sewage.

Preferably, the toilet bowl is characterized by having a Western-style toilet bowl supplied with cleansing water and a urinal not using cleansing water.

According to this configuration, since flushing water is not used, the urinal is not supplied with flushing water, and efficient use of flushing water can be achieved.

Another aspect of the invention for solving the above problems is a temporary flush toilet system using the vehicle-mounted temporary flush toilet described above, wherein the vehicle-mounted temporary flush toilet and the vehicle-mounted temporary flush toilet are mounted. and a treatment tank capable of collectively storing the stored sewage stored in the storage tank, wherein the stored sewage is treated after being stored in the treatment tank.

According to this configuration, a vehicle-mounted temporary flush toilet, a vehicle for transporting the vehicle-mounted temporary flush toilet in a state of being placed thereon, and a treatment tank capable of collectively storing the wastewater stored in the storage tank are provided. Since the sewage is treated after being stored in the treatment tank, it is sufficient to treat the stored sewage by storing it in the treatment tank. Thereby, the stored sewage can be treated without having to arrange a vacuum truck each time or without taking the trouble to transport the truck to the sewage treatment facility. As a result, it becomes possible to operate the vehicle-mounted temporary flush toilet efficiently.

Preferably, the sewage tank is equipped with an inflow valve for inflowing sewage at its upper end, and a discharge valve for discharging stored sewage at its lower end. A tank inflow valve is installed, and the head of the stored sewage at the position of the discharge valve is set larger than the head of the stored sewage at the position of the treatment tank inflow valve.

According to this configuration, the head of the stored sewage at the position of the discharge valve is set to be larger than the head of the stored sewage at the position of the inflow valve of the treatment tank. It can be discharged into a processing tank. That is, transfer equipment such as a pump for transferring the stored sewage to the treatment tank can be omitted.
