Description

The present invention relates to a toilet unit.

In a toilet unit used in a place where there is no water supply, a washing water tank for securing washing water is provided, and washing water is appropriately supplied from the washing water tank according to use. The wash water stored in the wash water tank can be used by storing rainwater in areas with high rainfall. If rainwater is not available, replenish it as appropriate.

In addition, toilet units used in places where there is no sewerage include those that decompose organic matter in a decomposition tank in which aerobic microorganisms have propagated, and those that store sewage in a sewage tank and appropriately pump and collect it. Furthermore, toilet units used in places where there is neither water nor sewage will operate by selectively combining these elements. Since it is often installed in a place where maintenance personnel cannot be dispatched, it is also necessary to replenish the washing water all at once when the pumping work is performed.

For example, Patent Document 1 proposes a form of a temporary toilet installed in a place where there is no water and sewage system. In this form, the washing water tank 11 and the sewage tank 24 are separately installed, and a mechanism for recovering the water vapor evaporated from the sewage tank and using it as washing water is provided.

However, the installation space may be limited in the place where the toilet unit is installed. It is desirable in operation that both the wash water tank and the sewage tank have sufficient capacity, but if they are to be increased, an extra installation space must be secured. Also, when transporting to install a temporary toilet, the larger the size is to secure the capacity of the washing water tank and the sewage tank, the heavier the load for transporting.

Therefore, an object of the present invention is to save space while securing the capacities of the washing water tank and the sewage tank in the toilet unit.

This invention
The above-mentioned problems are caused by a toilet unit having a sewage tank for storing sewage, a washing water bag which is a flexible bag installed in the sewage tank, and a pump for pumping the washing water filled in the washing water bag. Was solved.

In the toilet unit that stores both wash water and sewage, at the stage of starting use when the wash water is filled, it is decided to secure a space in the sewage tank to store the sewage after using the wash water. Become. Unless replenished, the residual amount of wash water decreases with use, and sewage accumulates in the sewage tank accordingly, so the capacity occupied by sewage in the sewage tank gradually increases. The amount of decrease in wash water and the amount of increase in sewage in the sewage tank are almost in a corresponding relationship, although there are some variations depending on the capacity occupied by the filth itself. The present invention takes advantage of this. If the wash water is put in a flexible bag installed in the sewage tank instead of being packed in a tank with a fixed shape, the wash water is put in the sewage tank, which is initially an excess space. It can be used as a space. As the use progresses, the amount of washing water remaining in the washing water bag decreases, and at the same time, the volume of the washing water bag becomes smaller due to being pushed by the increased sewage introduced into the sewage tank. That is, the space for securing the washing water and the space for storing the sewage can be shared, and the volume can be used seamlessly according to the increase or decrease.

In the toilet unit according to the present invention, the pipe for passing the washing water from the pump is pulled out from the mouth of the washing water bag and connected to the toilet bowl.
An embodiment in which the drainage pipe for passing the sewage from the toilet bowl is connected to a place other than the mouth of the washing water bag of the sewage tank can be selected.

Using the toilet unit of the present invention, an operation method of the toilet unit is realized in which the toilet bowl is washed with the washing water extracted from the washing water bag and the sewage is introduced into the sewage tank of the portion other than the washing water bag. it can.

The toilet unit according to the present invention can minimize the space required, is easy to install, and is easy to transport.

Hereinafter, the present invention will be described with reference to specific embodiments. FIG. 1A shows a side sectional view of the toilet unit 11, and FIG. 1B shows a plan sectional view.

The toilet unit 11 according to this embodiment is provided with a toilet bowl 12. Although the figure shows an embodiment including one Western-style toilet, it may be a Japanese-style toilet or a male urinal. Further, the number is not limited to one, and two or more toilet bowls 12 may be provided. However, in order to most preferably exert the effect of minimizing the space of the present invention, the toilet unit 11 provided with only one Western-style toilet bowl or Japanese-style toilet bowl is most effective.

The toilet unit 11 has a sewage tank 13. In this embodiment, it is installed under the floor of the space having the toilet bowl 12. The installation position of the sewage tank 13 is not necessarily limited. However, in terms of space saving, it is preferable to install it under the floor. If the sewage tank 13 is installed in the space used by the toilet unit 11, there is a feeling of oppression and the feeling of use inside the unit is impaired. Further, if an attempt is made to install a sewage tank adjacent to the usage space, the occupied area of the unit will increase. The sewage tank 13 itself is preferably made of resin or metal and can retain its shape. In addition, it is naturally necessary to have watertightness so that the sewage P itself does not leak to the outside.

The toilet unit 11 has a washing water bag 20 in the sewage tank 13. The washing water bag 20 is a flexible bag, which is watertight and can store the washing water W therein. It is necessary that the washing water W stored inside the washing water bag 20 and the sewage P dropped into the sewage tank 13 outside the washing water bag 20 are not mixed. Specifically, as the washing water bag 20, a bag made of a resin sheet such as rubber can be used. If it is too thin, it may be torn due to water pressure or other causes, so it must be durable enough not to be torn in normal use. Although it depends on the resin used, the thickness of the sheet is preferably 0.5 mm or more. On the other hand, if the sheet is too thick, the internal space may be maintained even if the internal cleaning water is reduced, so the thickness is preferably 5 mm or less.

The toilet unit 11 has a pump 21 in the washing water bag 20. The pump 21 is connected to the pipe 22 to generate a pressure for pumping the washing water W and sending it from the pipe 22 to the nozzle 23 in the toilet bowl 12.

The sewage tank 13 has a washing water outlet 15 on the upper surface which can be fixed by opening the mouth 20a of the washing water bag 20 upward. A lid is attached to the washing water outlet 15, and the lid is provided with a through hole 15a through which the pipe 22 can be attached. The pipe 22 is connected to the toilet bowl 12, and the introduced washing water W is ejected from the nozzle 23 in the toilet bowl 12. A valve is provided in the pipe 22, and the cleaning water W is ejected from the nozzle 23 only when the pipe 22 is operated when necessary. However, those valves, operating parts, etc. are abbreviated here.

Water is stored in the toilet bowl 12. A drainage pump 24 is attached to the lower part of the toilet bowl 12, and together with the ejection of the washing water W from the nozzle 23, the sewage P is discharged to the drainage pipe 25. In order to maintain the water surface in the toilet bowl 12, the drain pipe 25 extends upward once and then is introduced into the sewage tank 13 downward.

In this embodiment, the sewage tank 13 has a sewage inlet 14 on the upper surface in addition to the wash water outlet 15. The sewage inlet 14 is also provided with a lid, and the lid is provided with a through hole 14a that can be attached through the drain pipe 25. The sewage that has passed through the drain pipe 25 is dropped to the outside of the washing water bag 20 in the sewage tank 13.

Although not shown, an embodiment in which the washing water outlet 15 and the sewage inlet 14 are combined into one port may be used. In that case, the mouth 20a of the washing water bag 20 corresponds to only a part of the combined mouth, and the sewage P from the drain pipe 25 is dropped to the part other than the mouth 20a.

In any of the embodiments, the pipe 22 through which the washing water W from the pump 21 is passed is extracted from the mouth 20a of the washing water bag 20 and connected to the toilet bowl 12, while the sewage P from the toilet bowl 12 is connected. The drain pipe 25 through which the pipe passes is connected to a portion other than the mouth 20a of the washing water bag 20 of the sewage tank 13. As a result, the toilet bowl 12 can be washed with the washing water W extracted from the washing water bag 20, and the sewage can be introduced into the sewage tank 13 other than the washing water bag 20. According to this operation method, the occupied area of the washing water W and the sewage P can be separated in the occupied space of only one sewage tank 13.

FIGS. 2 to 4 show the situation when the toilet unit of the embodiment shown in FIG. 1 is operated. The initial state is shown in FIG. In the initial state, all the sewage P in the sewage tank 13 is in a pumped state or an empty state. On the other hand, the inside of the washing water bag 20 provided in the sewage tank 13 is filled with the washing water W.

As the usage progresses, it becomes as shown in FIG. The washing water W in the washing water bag 20 is reduced, and the washing water bag 20 is bent to reduce the volume. On the other hand, sewage P accumulates outside the washing water bag 20. The situation at the usage limit is shown in FIG. The washing water W in the washing water bag 20 is almost eliminated, and the washing water bag 20 is bent and the internal volume is almost eliminated. On the other hand, the outside of the washing water bag 20 is filled with sewage P. In this case, it is necessary to draw the sewage P and replenish the washing water W. In order to detect this, it is advisable to attach the water level sensor 31 to the outside of the washing water bag 20 in the sewage tank 13. When the water level sensor 31 detects that the sewage P exceeds a predetermined capacity, the communication means 32 notifies a remote management organization to that effect. As a communication means, a general method such as a fixed telephone line, a mobile phone line, or other wireless can be selected.
