Abstract
Description
[Technical Field]
[0001] The present invention relates to a portable toilet that can be easily and temporarily installed. [Background technology]
[0002] Temporary portable toilets are not only used at civil engineering and construction sites and event venues, but are also desirable in evacuation shelters and other locations during emergencies such as disasters, when lifelines such as water, sewage, and electricity may be cut off. However, in situations where there is no sewer system nearby and people are forced to live in evacuation shelters for a long period of time, portable toilets are required to be safe to use as well as have sterilizing and deodorizing functions to remove dirt and odors. For example, Patent Document 1 discloses a technology in which small pieces of wood on which microorganisms that decompose human waste are propagated are stored in a treatment tank, but the decomposition process takes time and it is difficult to deal with the odor that is generated.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-305008 Summary of the Invention [Problem to be solved by the invention]
[0004] An object of the present invention is to provide a portable toilet that is hygienic and takes safety into consideration. [Means for solving the problem]
[0005] The portable toilet of the present invention is characterized by having a toilet bowl, a treatment tank for decomposing and treating excrement, an ozone generator for supplying ozone to the space in the treatment tank, and an ion generator for supplying ions.
[0006] By supplying ozone and ions directly into the space of the treatment tank, the concentration of ozone and ions in the treatment tank, which is the source of odor, can be increased, resulting in sterilization and deodorization effects.For example, an ozone generator or ion generator can be installed without affecting the structure of the toilet itself. In the present invention, the treatment tank preferably has a sludge layer and an ozone-containing membrane layer formed above the sludge layer. By forming a membrane layer containing ozone on the upper side of the sludge layer, the membrane layer can prevent the odor from the sludge layer from flowing back toward the toilet room, making it easier to achieve a deodorizing effect.
[0007] In the present invention, the toilet has a drain outlet formed at the bottom of the bowl portion, and a flapper valve at the lower end of the drain outlet, and the flapper valve preferably has a contact portion with the drain outlet made of a silicone material or coated with silicone. This improves the durability and stain-preventing effect of the flapper valve, making it easier to close the discharge port with the flapper valve and more likely to prevent odors from flowing back into the toilet room.
[0008] In the present invention, the ion generating device may have an ion generating section having a cavity formed therein, and the cavity may extend from one end to the other end of the ion generating section. For example, the ion generating unit may be a double-cylindrical unit made up of an outer metal and an inner metal, with a different substance (e.g., ore or ceramic) housed between the outer metal and the inner metal, and may have a cavity inside the inner metal extending from one end to the other end. By providing the hollow portion inside the ion generating portion, ions can flow, making it easier to supply the ions to the treatment tank. [Effects of the Invention]
[0009] The portable toilet of the present invention can obtain sterilization and deodorization effects within the treatment tank by supplying ozone and ions directly to the treatment tank, and the ozone and ions can be supplied to the living space, making it highly safe for the human body and the environment in which the portable toilet is installed. [Brief explanation of the drawings]
[0010] [Figure 1] 1 shows an example of the configuration of a portable toilet according to the present invention. [Figure 2] A plan view of the toilet bowl is shown. [Figure 3] 3 shows an example of the structure of an ion generating unit. DETAILED DESCRIPTION OF THE INVENTION
[0011] An example of the configuration of a portable toilet according to the present invention will be described with reference to FIG. However, the present invention is not limited to this. A toilet bowl 10 is installed in a portable toilet room 1a, and a treatment tank 20 is installed below the toilet bowl. The treatment tank 20 may be provided, for example, under the floor of the toilet room 1a, with a portion of it located outside the toilet room 1b. The "toilet room" here refers to a closed space where people use the toilet 10. For example, an ozone generator 30 and an ion generator 40 may be provided outside the toilet room 1b so as to communicate with the treatment tank 20. This allows for easy maintenance and management of each generating device from outside the toilet, and the devices can be installed without affecting the structure of the toilet bowl or interfering with toilet users.
[0012] This embodiment is an example of a simple flush type toilet that uses a water supply tank 11 to clean the bowl portion 10a of the toilet, and has a drain outlet 10b formed at the bottom of the bowl portion 10a, with a flapper valve 12 provided at the lower end of this drain outlet. By opening and closing the flapper valve 12, the lower end of the discharge port 10b is opened or closed. When the lower end of the discharge port 10b is opened, waste flows down into the treatment tank 20. There are no particular restrictions on the shape of the flapper valve 12 as long as it can close the lower end of the discharge outlet 10b, but from the perspective of preventing odors from flowing back from the treatment tank 20, it is preferable that the abutment part 12a with the discharge outlet 10b be made of at least a silicone material or coated with silicone. This makes it easier to ensure durability and also makes the material water-repellent, making it less likely to get dirty. In this embodiment, as shown in FIG. 2, a flapper valve 12 has a substantially circular contact portion 12a (silicone) on its periphery.
[0013] The treatment tank 20 preferably has a sealed structure. A sludge layer 21 is formed on the bottom side of the treatment tank. For example, microorganisms having both aerobic and anaerobic decomposition properties may be added, and the sludge layer may include a separation layer with a high moisture content at the top. Ozone is supplied from an ozone generator 30 and ions (eg, negative ions) are supplied from an ion generator to the space 22 above the sludge layer 21 via connecting pipes 31 and 41, respectively.
[0014] The ozone generator 30 sends the generated ozone to the space 22 of the treatment tank through a connecting pipe 31 by means of an air supply means such as a fan or a pump. The connecting pipe 31 has a sealing structure to prevent odor leakage. For example, by connecting the treatment tank 20 and the connecting pipe 31 outside the toilet room 1b, it is easy to check the connection state, and the work is easier than assembling the treatment tank inside the toilet room where space is limited. Ozone can have sterilizing and deodorizing effects, for example, but if the pressure inside the treatment tank increases, there is a possibility that odors will leak out. Therefore, it is preferable to supply air to the extent that the space 22 is filled with air containing ozone. By turning the space 22 above the sludge layer 21 into a membrane layer containing ozone, it is easier to prevent the odor of the sludge layer 21 from rising.
[0015] The ion generator 40 can remove, for example, floating bacteria by discharging the generated ions into the space 22 of the treatment tank via a connecting pipe 41 having a sealed structure using an air supply means. The ion generating device 40 may have an ion generating section 42 that generates a weak current and has a substantially cylindrical shape, as shown in FIG. 3(a), for example. The ion generating unit 42 is a double cylinder made up of an outer metal M1 and an inner metal M2, as shown in the cross-sectional schematic diagram of FIG. 3(b), for example, and both ends are closed with caps 42a made of metal M1. A different substance X, such as ore or ceramic, is contained between the outer metal M1 and the inner metal M2, and a hollow portion 42b is formed inside the inner metal M2. The hollow portion 42b preferably extends toward the caps on both ends (from one end to the other end). The ion generating section generates a weak current due to a contact electrical phenomenon based on the potential difference caused by the contact between the ore and the ceramic, for example, and a magnetic field is generated around the weak current flowing. At the same time, a voltage is applied, generating an electric field around the area, which is thought to cause negative ions to be emitted to the outside. Furthermore, it is thought that the presence of the hollow section 42b causes a flow of ions. Examples of the metals M1 and M2 include stainless steel, copper, and aluminum alloys. Examples of the ores include gabbro, diorite, syenite, granite, and tourmaline. Examples of the ceramics include glass ceramics, but known materials may also be used, and the different materials may be two types of metals. [Explanation of symbols]
