Description

  The present invention relates to a moving body-mounted toilet that is used by being mounted on a camper, a welfare car, a long-distance traveling bus, a small ship, and the like, and in particular, includes a septic tank that decomposes and purifies excrement by microorganisms in addition to a toilet. The present invention relates to a toilet equipped with a purifying function for mounting on a moving body that enables the excrement excreted by a person on the body to be purified by the moving body.

  In general, a camper is equipped with a simple toilet that treats excrement each time. However, the conventional toilet is literally simple. For example, Japanese Patent Laid-Open No. 9-2171 describes a simple toilet in which the odor of excrement excreted by a person is discharged outside the vehicle by an exhaust device. Further, Japanese Utility Model Publication No. 6-81843 discloses that excrement excreted in a manure tank through a toilet is evaporated by exhaust gas with heat exhausted from an automobile engine, and the evaporated moisture is excreted by a chimney. A simple toilet that discharges outside the tank is described.

This type of in-vehicle simple toilet is a system in which excrement is temporarily stored in a container, discarded in an appropriate public toilet or facility toilet while berthed, the toilet tank is washed, and the toilet is attached to the simple toilet. However, in reality, if there is excrement in the space of a narrow moving body, it is not possible to completely prevent malodor. Therefore, the excreta must be disposed of immediately at an appropriate place. If a suitable disposal facility is not found while moving on a moving object, the excrement will be present in a narrow office for a long period of time.
JP-A-9-2171 Japanese Utility Model Publication No. 6-81843

  In view of the problems in the conventional in-vehicle simple toilet as described above, the present invention makes it possible to decompose the excrement by microorganisms that inhabit the excrement of excrement as a nutrient source, and eliminate the waste disposal process.

Can also be reduced.
In particular, in order to maintain an appropriate temperature necessary for the growth conditions of microorganisms inhabiting the fungus body, in addition to the heat source of the conventional heater 13, the waste heat utilization of the radiator 3 for cooling the engine of the moving body is adopted. The heating conditions are good. On the other hand, the agitation drive motor 7 for the fungus bed has a controller 11 that can use both the battery power source 10 for the moving body and an external AC power source, so that it can be used during traveling and at rest. The toilet with a septic tank that uses this type of self-extinguishing microorganism can be used for various purposes such as long-distance buses, nursing vehicles, and marine products.

Hereinafter, the best embodiment of the present invention will be described in detail.
The septic tank of the toilet with a purification function for mounting on a mobile body is usually made of a material such as stainless steel in consideration of heat conduction and corrosion. The septic tank can be operated with a fungus bed inhabited by microorganisms, managing the excrement, temperature and humidity. The bottom of the septic tank is equipped with a heater that heats using an AC power source. In order to improve the heat conduction of the heater, a soaking plate is fixed integrally with the septic tank. Therefore, heat conduction with the outside of the septic tank is good. In this invention, it arrange | positions so that piping from a radiator may meander on this soaking | uniform-heating board, and is connected with the radiator. The material of this pipe is usually a copper pipe, and the heat conduction to the soaking plate is good. Therefore, only during driving, the AC power supply of the heater is not used, the septic tank is heated only by the exhaust heat temperature from this pipe, and the appropriate temperature of microorganisms in the fungus bed is controlled. Further, since this exhaust heat cannot be used during berthing, the heater is heated by an AC power source to warm the septic tank temperature.

Hereinafter, examples of the present invention will be described in detail with specific examples with reference to the drawings.
1 and 2 show an embodiment of the present invention, which is an example in which a toilet 1 with a septic tank is mounted on a camper, FIG. 1 is a plan view, and FIG. 2 is a side view thereof. Examples of the mobile body 20 on which the toilet 1 with the purification function for mounting the mobile body is mounted include a welfare vehicle, a construction work vehicle, and a small ship in addition to the camper.

The cabin 21 of the moving body 20 is equipped with a toilet 1 with a septic tank that uses microorganisms that decompose the excrement of a user who is in the vehicle into water and carbon dioxide by microorganisms.
1 and 2, 2 is a toilet having a toilet seat lid, and 6 is a septic tank 6 for receiving excrement under it. Reference numeral 3 denotes an engine portion cooling radiator portion, and a circulating cooling water pipe 4 for cooling the radiator portion 3 is provided. In the illustrated embodiment, the pipe 4 is connected to the septic tank 6 of the toilet 1 with a septic tank using microorganisms. The toilet odor is discharged to the outside through the exhaust duct 5. Reference numeral 22 denotes an exhaust port provided on the roof of the moving body, and is provided with a cap for preventing rainwater from entering.

FIG. 3 is a block diagram showing electricity, a piping system, etc. for driving the toilet 1 with a septic tank. FIG. 4 is an external view of the toilet 1 with a septic tank using microorganisms. With reference to the block diagram of FIG. 3, the mechanism of a toilet with a purifying function for mounting a mobile body according to an embodiment of the present invention will be described.
When the toilet seat lid of the toilet bowl 2 of the toilet 1 with a septic tank using microorganisms is opened and a person defecates and excrement is excreted in the septic tank 6, the drive motor 7 is put in a certain time. Start driving. At this time, the fungus bed 8 previously put in the septic tank 6 is stirred together with the excrement by the stirring blade 9. As a result, air is continuously sent into the excrement and the fungus bed body 8, and this air reaches every corner of the excrement and the fungus bed body 8. As a result, aerobic microorganisms effective for the decomposition of excrement propagate, and the growth of anaerobic microorganisms, which are mainly spoilage bacteria, is suppressed.

  Normally, when the vehicle is running, the drive motor 7 is operated via the vehicle battery power source 10. On the other hand, when the AC power source can be used while the vehicle is at rest or temporarily stopped, the AC power source is connected by the plug 12 and is rectified and converted to the DC power source via the control circuit 11. I can drive.

  The excrement is decomposed into water and carbon dioxide gas by the microorganisms growing in the mycelium 8 and processed. In the toilet 1 with a septic tank using this kind of microorganism, it is usual to heat the heater 13 for keeping warm outside the septic tank 6 in order to make the growth conditions of the microorganism active. In the illustrated embodiment, in addition to this, the piping pipe 4 for circulating cooling water connected to the radiator 3 for cooling the engine section meanders on the soaking plate 14 that is in contact with the outer periphery of the bottom of the septic tank 6. It is piped. For this reason, it has the structure where heat conduction of exhaust heat can be used more effectively. On the other hand, as described above, when operating with an AC power supply, it can be operated by being introduced from the plug 12.

The detailed structure and mechanism of the septic tank 6 in the illustrated embodiment will be described with reference to FIGS.
When the toilet seat lid 2 of the toilet 1 with a septic tank using microorganisms is opened and the excrement of the boarding vehicle is put into the septic tank 6, the driving motor 7 starts operation after a certain period of time. By this operation, the stirrer blade 9 for stirring the fungus bed repeats normal rotation and reverse rotation, and the excrement is mixed with the seed bed chips. In this fungus bed 8, microorganisms are alive, and the fungus bed is kept at a suitable temperature and humidity, and begins to be active with the excrement of feces and urine as a nutrient source, and the organic matter contained in the excrement is watered. And carbon dioxide. This is the mechanism of the toilet 1 with a septic tank using microorganisms.

  The illustrated embodiment is an example in which a toilet 1 with a septic tank using this microorganism is mounted on a camper. Taking advantage of the camper in particular, the exhaust heat of the radiator 3 is utilized, the circulation pipe 4 is brought into contact with the soaking plate 14 at the bottom of the septic tank 6, and the nursery is kept warm by utilizing the exhaust heat of the circulated hot water. It has a structure that can be maintained. The septic tank 6 has a built-in heater 13 for normal heating, and controls the temperature in the septic tank so that the growth temperature of the microorganisms in the fungus bed is reached. The heating heater 13 is covered with a soaking plate 14 in order to improve the heat conduction of the septic tank 6.

  A heat insulating material 16 is interposed between the septic tank 6 and the outer frame 15. In the illustrated embodiment, the above-described hot water circulation piping pipe 4 is further brought into contact with the soaking plate 14 to absorb the exhaust heat of the hot water. The piping pipe 4 is usually a copper pipe and is circulated through the radiator 3. Therefore, heat conduction to the soaking plate 14 is also good. This structure is formed, and the septic tank 6 is warmed through the heat source of the exhaust heat circulation piping pipe 4 during traveling. The pipe 4 extends from the radiator 3 to the heat equalizing plate 14, meanders there and returns to the radiator 3, and has a piping structure in which the cooling water of the radiator 3 can be circulated.

  On the other hand, when there is an alternating current power source when the vehicle is not anchored and not traveling, the power source is connected to the alternating current power source by the plug 12 and heated by the heat source of the heater 13. In the illustrated embodiment, the driving motor 7 uses a battery power source 10 and is operated via a control circuit. However, the AC power source is used as a control circuit in a place where the AC power source can be used, such as during berthing. The driving motor 7 can be operated after rectification conversion.

  In recent years, toilets with septic tanks that use this type of microorganism have been reviewed rapidly, and are used in places where it is difficult to dispose of excreta, such as toilets for people engaged in specific management areas in nuclear power plants, highlands, and parks. It has been. However, in mobile vehicles such as campers, it is difficult to mount septic tanks using microorganisms in order to keep the inhabiting conditions of microorganisms inhabiting the bacteria bed in the septic tank constant.

  In the present invention, heat retention from the outside of the septic tank 6 during traveling is performed by using the exhaust heat from the pipes from the radiator 3 and heating the septic tank temperature via the soaking plate 14. By this heating, it was confirmed that the temperature of the septic tank can be sufficiently kept to a temperature at which microorganisms can grow without using a heater. On the other hand, during berthing, the heater can be heated using an AC power source to keep it warm. Further, the driving motor can be operated in both the direct and direct modes.

  In the embodiment described above, a toilet with a septic tank using microorganisms is mounted on a camper as the moving body 20. And the piping pipe of the warm water circulation for the cooling of the radiator 3 mounted in the camper is extended, and the waste heat is utilized by contacting the heat equalizing plate 14 that keeps the septic tank 6 warm. By using this waste heat, the septic tank is heated while traveling. By using this waste heat, the heat conversion of the radiator is improved.

  The heater 13 is heated via an AC power source only during a period when the exhaust heat is not available during berthing. On the other hand, an ordinary camper has a backup AC power supply in addition to a DC power supply. Therefore, when it is impossible to pull in the AC power source, the backup AC power source can be temporarily used to heat the AC power source. The drive motor 7 that stirs the fungus bed in the septic tank 6 for a fixed time is always operated by the battery 10, but can be operated by rectifying the control circuit unit even with an AC power supply. With these configurations, toilets with septic tanks using microorganisms according to the present invention can be modified according to the purpose of use, such as marine relations such as small ships, buses that travel long distances, mobile buses for nursing care, etc. The use and demand can be greatly expected in the future.
