Description

Technical Field

[0001] The present invention relates to a portable toilet unit that can be used as a simple toilet in an emergency such as when a disaster occurs.

Background Art

[0002] When a natural disaster such as an earthquake or heavy rain occurs, or a large-scale fire occurs and permanent toilets become unusable, temporary toilets are installed as an emergency measure until recovery is completed. However, conventional temporary toilets have to be transported by vehicle to the affected area and installed there. Nevertheless, when a large-scale disaster occurs, roads themselves may be damaged and become impassable for vehicles. In such cases, it takes a considerable number of days to restore the roads, and the inability to use temporary toilets during this period poses problems not only in terms of hygiene but also in terms of the stress imposed on disaster victims. Furthermore, even for temporary toilets, there is strong demand for flush toilets, such as small-volume flush toilets, from the perspectives of ease of use and hygiene.

[0003] For example, Patent Document 1 and the like disclose a movable toilet bowl, which only allows the installation location to be moved and is not intended for use in situations such as disasters.

Means for Solving the Problem

[0006] The portable toilet unit according to the present invention is characterized in that the toilet bowl unit is housed in a case body that serves as a water storage tank for the flushing water used to flush the toilet bowl unit, making it portable. The present invention is characterized by housing the toilet unit in a case that serves as a water tank when used as a toilet, and making this set portable. In this way, the portable toilet unit can be stored in community centers and various public facilities during normal times, and in emergencies such as disasters, it can be taken out of storage and used as a temporary toilet. As long as the toilet unit and the case that serves as the water tank for flushing can be carried together as a set, there are no particular restrictions on the means of transportation. For example, one example of a case configuration is one in which the case body has a base on which the toilet unit is placed and a case body that serves as a cover for the toilet unit placed on the base, and when the case body is turned over it becomes a water tank. The base can be made movable by attaching casters, or it can be fitted with handles or straps for carrying.

[0007] In the present invention, it is preferable that the toilet unit is equipped with a pressurized pump for pumping sewage and waste to an external drainage treatment system such as a sewer or septic tank, and it is even preferable that it is equipped with a mobile battery as the power source for operating the pressurized pump.

[0008] In the present invention, it is preferable that the case body is equipped with a water supply pump for supplying flush water to the toilet bowl unit, and it is preferable that the water supply pump is equipped with a mobile battery as the power source for operating it. [Effects of the Invention]

[0009] The portable toilet unit according to the present invention can be stored during normal times and easily taken out of storage and used as a temporary toilet in the event of a disaster. For example, it can be used as a stockpile of toilets for emergencies. Furthermore, in the toilet unit according to the present invention, a tent or the like may be added to the set for the surrounding toilet room. [Brief explanation of the drawing]

[0010] [Figure 1] This shows a perspective view of the toilet unit and other components housed inside the case. [Figure 2] This example shows a case structure consisting of a main body that becomes a water tank when turned inside out, and a base that serves as the lid for the water tank. [Figure 3] (a) to (d) show the procedure for using it as a toilet unit. [Figure 4] An example of a toilet unit configuration is shown. [Modes for carrying out the invention]

[0011] An example of the configuration of the portable toilet unit according to the present invention will be described below with reference to the figures, but it is sufficient that the toilet unit can be stored and carried, and is not limited to this embodiment.

[0012] Figures 1 and 2 show the toilet unit 20 housed in the case body 10 and assembled. Figure 1 shows a transparent view of the inside of the case body 10 from above (with the case body 10a removed), and Figure 2 shows the toilet unit 20 placed on the base 11 with the case body 10a, which covers it, removed and lifted. Figure 1 schematically shows the containment state, but the containment method is not limited to this. As shown in Figure 3(a), the main body of the case 10a can be removed and turned upside down to become a water tank. The base portion 11 also functions as a lid for the water tank, as shown in Figure 3(b). In this embodiment, the base portion 11, which serves as the lid, is fitted with casters 11a, and the resulting structure functions as a trolley. Additionally, handles or straps may be attached for carrying by a person. In addition, for smaller versions, the toilet unit 20 can be housed inside the case 10 so that a person can carry it on their back.

[0013] A toilet unit 20, a water supply hose 31, a drainage hose 32, a connection cord 33 and the like are housed inside the case body 10 in a stored state. Note that, as shown by the dotted line in FIG. 3(a), a mobile battery 40 may be housed as needed. Furthermore, although not shown in the drawings, tents that surround the toilet unit 20 and form a toilet room may be housed as a set in the case body 10. As described above, when the mobile battery and the tents are housed as a set, a toilet can be installed both indoors and outdoors in an emergency. Here, the tents only need to surround the toilet unit and can be used as a simple toilet, and may be curtains, partitions or the like. Further, the device may be housed in a temporary toilet house so as to be portable.

[0014] In an emergency such as a disaster, it is necessary to take the device out from the storage location to form a temporary toilet, and the procedure therefor will be described with reference to FIG. 3. As shown in FIG. 3(a), the case main body portion 10a of the case body 10 is removed from the portable toilet unit according to the present invention and turned inside out. The case main body portion 10a and the base portion 11 may be detachably fastened to each other. Further, in the present embodiment, a water feed pump 12 is provided on an inner side of the case main body portion 10a. FIG. 3(b) shows a state where the toilet unit 20, the hoses, the connection cord, and the mobile battery 40 are unloaded from the base portion 11. In FIG. 3(c), the toilet unit 20 and the water feed pump 12 are piped via the water supply hose 31, and the water feed pump 12 is electrically connected via the connection cord 33a to an outlet provided in the toilet unit. Further, the drainage hose 32 is used to connect the drain port of the toilet unit to an external sewer 50 or a sewage tank or the like via the hose. Here, when a detachable cap is provided at the drain port, the cap can be attached to the drain port after use as a toilet to facilitate storage. Next, the temporary toilet is completed by connecting the control unit of the toilet bowl unit using the mobile battery 40 and the connecting cord 33.

[0015] Figure 4 shows an example of the configuration of the toilet unit 20 used in the present invention. The toilet bowl portion 21 is connected to the casing portion 22c of the pressure pump 22 via a water intake portion 21a located at the bottom of the bowl portion 21. The casing section 22c has an impeller section 22b whose rotation is controlled by the motor section 22a. Connect the drain hose 32 to the drain section 23 of the toilet unit 20. As shown by the dotted line in Figure 3(d), the temporary toilet is completed and becomes a flush toilet by injecting water W into the case body 10a. Furthermore, in this embodiment, an electrically controlled water pump is used to supply water from the case body 10a, which serves as a water storage tank, to the toilet unit 20. Therefore, there may be a difference in height between the toilet unit 20 and the case body 10a, providing greater flexibility in the installation location. Furthermore, since wastewater and other wastewater from the toilet unit 20 are drained using a pressure pump, the difference in elevation with the sewer system or other drainage system is not a concern. In the toilet unit 20, a water supply pump is activated by an operation signal from the control unit of the toilet unit, and the bowl is cleaned. Similarly, a pressure pump is activated by an operation signal from the control unit, and wastewater is drained. By operating the water supply pump and the pressure pump in a time-series manner, the output load on the mobile battery is distributed. Therefore, it is preferable that the water supply pump and pressure pump be submersible pumps, self-priming pumps, etc. Since the wastewater can be discharged into sewers and other systems using a pressure pump, odor generation is suppressed, making it hygienic. In this invention, the toilet unit, water tank, and hoses may be made detachable without the use of tools, or a handrail may be provided on the toilet unit to make it easier for the elderly to use. The case body may be made of resin to reduce weight and make it easier to handle, and the top and bottom surfaces may be made flat so that they can be stacked when stored. The case body 10 can house and store the toilet unit 20, hoses, and cords, making it hygienic. Furthermore, when installing outdoors, the toilet unit may be provided with anchoring points to ensure stable fixation against strong winds, and mudguards may be provided around it.
