Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention heats urine that is physiologically excreted from the human body,
The present invention relates to a urine evaporator capable of evaporating most of the components of water, and more particularly, to a urine evaporator with a water recovery function which can be used for purposes such as hand washing by recovering water components from evaporated water vapor. .

[Conventional technology]

In the living space in which humans live, there is always a toilet for processing urine excreted from the human body. In a normal house, house, or office, a fixed toilet is installed as an independent room, which is useful for collecting excrement.

However, when it is necessary to install a toilet at a construction site, in the mountains, or in a place where sewerage facilities are not provided, such as a riverbed, a temporary toilet that can be moved was used.

In such a conventional temporary toilet, a tank for storing the excrement is provided to store the excrement, and the excrement is collected by a vacuum car or the like at a later date. However, for example, in a construction site of a high-rise building, a closed semiconductor factory, a nuclear power plant, etc., a tank for storing excrement cannot be installed, which is extremely inconvenient.

From such a demand, an evaporation type toilet has been developed in which the excrement is vaporized and released as water vapor into the air to treat the excrement, thereby eliminating the work of recovering the excrement. In this evaporation type toilet, a heating element such as a heater is housed in a closed container, and the heat of the heater can be used to sanitarily evaporate the water in the excrement (for example, Japanese Patent Application No. 63 years 113269).

This new evaporative toilet has a tank to store urine,
It was composed of a heater housed in this water tank and a deodorizing means for removing a bad odor from the water vapor discharged from the water tank. With this configuration, the collected urine can be efficiently processed by converting it into water vapor and releasing it into the atmosphere.

However, such evaporative temporary toilets are usually used in places where water and sewage are not installed, and in many cases water supply such as hand washing is not installed at the same time. For this reason, even when a person who uses this temporary toilet washes his / her hands after use, there is no suitable water supply facility, it is unsanitary, and a feeling of uncleanness remains after the toilet.

[Problems to be Solved by the Invention]

As described above, in the conventional evaporation type temporary toilet, the function works extremely effectively, but for the user, it is merely excreted to evaporate the urine. Therefore, since the fingertips remain unclean after the urination and move to the next operation, a feeling of uncleanness always accompanies the toilet, which is a halfway function. For this reason, even in a water evaporation type temporary toilet,
It was desirable that hand wash water be supplied after use.

The present invention has been made in view of the above points, and an object thereof is to provide a urine evaporator having a water recovery function, which can supply hand washing water.

[Means for solving problems]

In order to achieve the above object, the urine evaporator with a water recovery function of the present invention includes a water receiver that receives urine excreted from a human body, a closed water tank that stores urine that has flowed in from the water receiver, and this water tank. An evaporation mechanism that is housed inside and that evaporates urine in the water tank, a water supply mechanism that circulates urine from the lower part of the water tank to an upper part inside the evaporation mechanism, and an ejector that discharges vapor evaporated from the water tank. A condenser for recovering the water content of the steam passing through the discharger and a reservoir for storing the water recovered by the condenser and discharging the water above the water receiver as needed It is characterized by.

Here, the evaporation mechanism includes an evaporation structure that is housed in the water tank and that introduces urine from a lower portion and evaporates vapor from an upper portion.

In addition, the evaporation structure is a hollow solid body that opens up and down, and the lower opening is located slightly above the bottom of the water tank and the upper opening is located above the upper water level of the water tank. And a compartment having heat insulation ability, and a heater housed in the compartment.
A plurality of heat storage bodies housed in the internal space of the partition body are provided.

In addition, the deodorizer is a heating pipe that heats steam from the upper part of the water tank, a catalyst body that removes odors from the steam reheated by the heating pipe, and deodorized steam that has passed through the catalyst body.

[Action]

In the past, the water vapor evaporated by the evaporator was diffused as it was into the atmosphere from the chimney. However, in each of the above inventions, the vaporized water vapor is condensed by the cooler to collect water. Further, in another invention, when the storage tank is full, water is not collected.

The recovered water is close to distilled water, has extremely high purity, and is hygienic. The collected water is temporarily stored in a recovery tank and is supplied as water for washing the fingertips, etc. after using the toilet.

Therefore, it is possible to recover a part of the vaporized water vapor as water and reuse it as washing water while vaporizing the urine of the person who uses the stool. If an evaporative temporary toilet is installed, water for hand-washing can be self-supplied at the same time, and a circulation cycle can be established because the source of washing water uses excreted urine as a material.

In addition, since the user can wash his / her fingertips with water after the urination, the feeling of cleanliness can be maintained and the use can be extremely hygienic.

Further, FIG. 4 is an explanatory view showing the entire flow channels of the fluid and gas in FIGS. 2 and 3 in a simplified manner.

Next, the operation of this embodiment will be described.

When using the urine disposal device 1, a person who intends to use the urine faces the urine disposal device 1 and receives the urine from the water receiver 5.
To release. Then, the urine collected by the water receiving body 5 passes through the trap 30 through the injection pipe 12, and passes through the trap 30.
It is stored inside. And the urine 50 stored in the aquarium 11
Are stored until a predetermined capacity is reached.

When the urine 50 is stored in a predetermined amount or more, the heater 34 is energized to heat the urine and the heat storage balls 37 in the compartment 31. At the same time, the air pump 14 is operated to supply air from the outside into the water tank 11 through the water supply pipe 15. When the air from the air pump 14 is supplied to the water supply pipe 15,
The air that has passed through the water supply pipe 15 passes through the suction port 38 and is ejected from the upper end opening of the water supply pipe 15 that is bent in a U shape. At this time, the water supply port 38 is the urine 50 stored in the water tank 11.
Since it is in contact with the urine 50, the urine 50 is sucked into the water supply pipe 15 through the suction port 38 and flows in the water supply pipe 15 in a state where the urine 50 and air are mixed intermittently, and the urine 50 is divided into compartments.
It will gush into the upper space of 31.

Although the urine 50 and the heat storage body 37 are heated by the heater 34 described above, the urine 50 around the water tank 11 is thermally insulated by the partitioning body 31, so that the urine 50 is in another area in the water tank 11. Without heating the urine, only the small volume of the urine in the compartment 31 is heated and evaporated.
At this time, since the heat storage body 37 is formed of a material that retains heat such as ceramic, it absorbs the heat of the heater 34 and
37 itself will also dissipate heat from its surface. Since the total surface area of all the heat storage bodies 37 is large,
The heat generated from 37 heats the urine 50 around it, and the heating speed becomes extremely high. Furthermore, since the space inside the partition 31 is filled with the heat storage balls 37, the volume of the urine 50 held inside the partition 31 is small, and since the urine 50 of this small volume is heated and evaporated, Due to the large surface area of the heat storage balls 37, the evaporation rate of the urine 50 is extremely high.

When the stored urine 50 in this aquarium 11 is evaporated, the aquarium
Saturated water vapor will be accumulated in the upper space inside 11.
However, the air from the outside is evacuated by the air pump 14.
Since it is always sent into the inside of the water tank 11, saturated water vapor in the upper space of the water tank 11 is discharged through the discharge pipe 13 to the deodorizer 16
Sent in the direction of. Thus, saturated steam flows from the discharge pipe 13 into the heating pipe 41.

When the saturated steam passes through the heating pipe 41, the reheating heater 42 is energized, and the reheating heater 42 is always heated. Then, the saturated water vapor evaporated from the urine 50 comes into contact with the reheat heater 42, is reheated, and is discharged under the heating pipe 41. Saturated water vapor of the urine 50 evaporated in the water tank 11 contains components such as ammonia and bromine that make a bad odor. The steam containing the bad odor is heated by the reheating heater 42, and then the catalytic body is heated.
By touching 43, the malodorous component is oxidized and changed to be odorless. At this time, since the fan 44 of the air exhaust unit 17 is operating, the air inside the deodorizer 16 is sucked to the outside and transferred to the diffusion pipe 8 through the joint pipe 18.

At this time, the valve 45 of the switching device 19 is in the position shown by the solid line in FIGS.
Flow in 20 directions. Next, in the inflowing cooling pipe 46,
The fan 47 constantly sends cool air to cool the heated saturated steam, and the water is dropped as water drops. Since the opening of the water pipe 23 is set upward in the lower part of the cooling pipe 46, the cooled and dropped water is collected by the water pipe 23 and flowed into the water tank 24. Then, it is stored in the water tank 24 for the next purpose of use. afterwards,
The water vapor cooled by the cooling pipe 46 flows into the diffusion pipe 8 from the discharge pipe 22 and is discharged to the outside from above the diffusion pipe 8.

Now, a person who excretes using the urine disposal device 1 can drain the distilled water in the water tank 24 by rotating the cock 7. Distilled water flows out from the cock 7 and the fingertips can be washed. Then, the water that has flowed out of the cock 7 and washed hands and the like falls on the water receiver 5,
It is collected in the water tank 11 through the trap 30 in the aforementioned circulation cycle.

However, the capacity of the water tank 24 is limited, and if water is continuously cooled to collect water, the capacity exceeds the capacity. Therefore, when the distilled water in the water tank 24 is stored in a predetermined amount or more, the valve 45 is switched to the position of 45A indicated by the broken line in FIGS. 2 and 3. Then, the saturated steam drawn from the joint pipe 18 passes through the switch 19 and directly flows out to the diffusion pipe 8. For this reason, the water vapor that has become unnecessary to recover water will be ejected and diffused into the atmosphere without recovering the water component.
