DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to human waste treatment for treating human waste outdoors, without purification facilities, in transportation systems such as ships and trains, and in tunnels that are closed from the surroundings and do not allow vacuum cars to enter. More particularly, the present invention relates to a catalyst cleaning mechanism of a human waste treatment apparatus that can automatically remove dust attached to a catalyst.

2. Description of the Related Art In a general house, human waste excreted from the human body is generally discharged to a sewer pipe by a flush toilet or the like, or temporarily stored in a septic tank for purification and then discharged to a river. However, when performing outdoors, for example, in a venue where a large number of personnel such as an athletic meet, a trade fair, and a rally are held, a temporary toilet is conventionally provided to eliminate the physiological phenomenon of the participants.

[0003] As described above, in the conventional treatment of human waste outdoors or in a place without a purification facility, a movable temporary toilet is used. However, most of them have a structure having a toilet tank for temporarily storing human waste, and human waste excreted from the human body is directly stored in this toilet tank. Therefore, after using the temporary toilet, the human waste stored in the toilet tank must be collected by a vacuum car or the like and transferred to a human waste processing facility. For this reason, the post-collection processing is required, and the post-processing is troublesome and unsanitary.

[0004] Transportation systems such as trains, buses, ships, and the like that travel long distances are provided with a dedicated tank for storing excreted human waste. After the processing, a method of collecting by a vacuum car at a terminal station or a relay point was generally used.

[0005] As described above, in the conventional disposal of toilets or movable transportation, human waste is mostly stored while being excreted from the human body and then collected. For this reason, any of the storage method, the recovery method, and the treatment method has to be said to be non-modern and extremely unsanitary. Therefore, when the temporary toilet has been used for a long period of time, excreted human waste remains in the tank, causing odor. In addition, since the operation of cleaning the temporary toilet after use is disliked by workers, it is not preferable from the viewpoint of modernization of maintenance of the temporary toilet and the toilet of transportation.

Under such circumstances, various methods for sanitary disposal of human waste have conventionally been considered. For example, there is a method of disinfecting and deodorizing by inputting a chemical agent together with human waste. This method is often used for transportation such as Shinkansen, but since urine containing chemicals circulates between the tank and the toilet, the water flowing through the toilet becomes dirty after a long-term use.
It had a bad smell and was unpopular for users. Further, in order to empty the tank and prepare it for the next use, a large amount of chemical must be introduced into the tank, which has the disadvantage of increasing the cost of the chemical.

[0007] Further, a method has been considered in which human waste is stored in a bag of vinyl or the like and packed to prevent the emission of odor. However, a large amount of plastic bag must be used for each excretion, which increases the processing cost and requires a process for separating human waste from the plastic bag at a later date. With this method, the process until packing is relatively easy,
Subsequent processing is cumbersome, and the processing facility becomes large.

Further, a method has been considered in which excreted human waste is stored in a closed evaporation container, and the human waste is directly heated and evaporated by the heat of a burner. For example, patent publication Showa 4
No. 17236, Patent publication No. 2545, Showa 1974, Patent publication No. 3149, Showa 50, Patent publication 58
No. 239, Japanese Patent Publication No. 110268/1982, and Japanese Patent Publication No. 55415/165415 are known. However, in these methods, since the flame of the burner is squirted into human waste to evaporate from the surface,
Moisture, a major component of human waste, cannot be evaporated efficiently,
It required a lot of energy to completely process human waste.

[0009] Further, with these configurations, the evaporating container is not cleaned after the human waste is dried, and the residue that cannot be evaporated from the human waste accumulates on the bottom of the evaporating container in a long-term use. The thermal efficiency became worse. In such a case, in order to clean the residue, the apparatus must be disassembled and maintenance must be performed each time, and there is a disadvantage that the maintenance is troublesome and expensive.

As described above, there are many problems in the treatment of human waste in a temporary toilet, and it is difficult to completely excrete human waste in the temporary toilet. Due to such social demands, the same inventor as the applicant of the present application has proposed a human waste processing apparatus that can heat the human waste to evaporate water, which is a major component of the human waste. The proposed human waste processing apparatus is provided for use in a temporary toilet, and a sealed drying pot (heat-resistant evaporating vessel) for storing human waste is provided in the apparatus. A rotatable stirring blade is rotatably supported, and the drying pot has a configuration in which a plurality of heat accumulators that roll on the inner bottom together with human waste according to the rotation of the stirring blade are housed.

The drying pot is heated from the outside to heat the waste in the drying pot, and at the same time, by rotating the stirring blade, the waste can be mixed and the moisture of the waste can be quickly evaporated. At the time of this evaporation, the spherical heat storage element rolls at the bottom of the drying kettle to uniformly heat the temperature of the human waste, and to transfer the heat of itself to the human waste to increase the heating rate. (For example, Japanese Patent Application No.
No. 4150).

This mechanism is basic, and the inventor has successively proposed an improved human waste treatment apparatus. Japanese Patent Application No. 164594/1990 discloses a configuration in which a pipe for supplying air to a drying pot and an exhaust pipe are connected, and the exhaust pipe is connected to a dust collector and a condenser. In this mechanism, the water vapor of the human waste evaporated inside the drying pot is condensed and collected, and can be circulated and used for washing water.
Dust remaining in the drying pot after drying of human waste is sucked and collected together with air, and the dust can be separated from air by a dust collector. By this mechanism, moisture can be collected from the human waste put into the drying pot, and the non-evaporable dust remaining in the drying pot after the drying of the human waste can be cleaned, so that the human waste processing apparatus can be used continuously. It is.

In Japanese Patent Application No. 411577/1990, a human waste treatment apparatus is unitized so as to be easily installed in a temporary toilet. In this mechanism, the structure of the drying pot is formed in a cylindrical shape so that human waste can be introduced from the side of the drying pot. For this reason, there is no need to dispose the toilet on the upper part of the drying pot, and the height of the apparatus can be reduced.

In Japanese Patent Application No. 412559/1990, a storage tank for storing urine collected by a urinal is provided, and the storage tank and the urinal are connected by an ejection pipe. In this configuration, urine and urine are excreted in the urinal, and urine is separated so as to be collected in the urinal. It can be put into a drying pot. For this reason, the toilet can be cleaned with urine, and the temporary toilet can be flushed even in a place where water supply cannot be installed.

[0015] Furthermore, in Japanese Patent Application No. 03-67538,
A mechanism is shown in which a liquid level sensor is inserted from the side of the drying pot, and the position of the liquid level of the human waste put into the drying pot can always be detected. In this mechanism, by detecting and judging the liquid level of the human waste, it is possible to prevent a large amount of human waste from being temporarily supplied, thereby preventing the ability of the human waste to evaporate, and to prevent a failure due to overflow. This can prevent the occurrence.

In Japanese Patent Application No. 189280/1991,
A reheating box with a built-in heater is arranged between the blower and the catalyst box, and a bypass is provided between the catalyst box and a pipe connecting the drying pot and the dust collector. With this configuration, the air from the drying pot can be made to flow to the catalyst box by the bypass during the evaporating process of the excrement, and the air flow can be made more efficient. Further, during the cleaning process of the drying pot, the bypass is closed so that the air containing dust can flow to the dust collector as it is.

Japanese Patent Application No. 189281/1991 is an improvement of the Japanese Patent Application No. 189280/1991. A bypass pipe is connected to a pipe connecting the drying pot and the dust collector, and the end of the bypass pipe is connected to the end of the bypass pipe. Is a configuration in which the negative pressure side of the ejector is connected and the catalyst box is connected to the ejector. In this configuration, when the bypass pipe is open, the air in the drying pot is forcibly sucked by the ejector and made to flow into the catalyst box, so that the air flow efficiency of the drying pot is increased and the evaporation is promoted. effective.

In Japanese Patent Application No. 265237/1991, a trash collection box is connected to an exhaust pipe of a drying oven, and a trash bag formed of paper, cloth, or the like is stored in the trash collection box. In this configuration, when cleaning the drying pot, air containing dust flows into the garbage bag, and only dust passes through the garbage bag and the dust can be separated. There is an effect that dust can be separated more reliably than a cyclone type dust collector.

[0019] In Japanese Patent Application No. 051170/1993,
The toilet and the human waste treatment apparatus are separated, and the human waste put into the toilet is stored in a tank, and then the evaporating and drying process can be continuously performed in a badge type. In this human waste processing apparatus, an opening for introducing human waste is formed at the top of a slightly spherical drying pot that can be rotated on a horizontal axis, and a spherical heat storage element is stored inside the drying pot. This is a configuration in which a burner capable of heating is provided. With this configuration, the human waste put into the drying pot is evaporated and dried by the heat of the burner. During this process, the human waste can be stirred by the heat storage body by swinging the drying pot, and after the drying, the drying pot is rotated. This allows dust to fall from the opening.

In Japanese Patent Application No. 121968/1993, a switching valve is interposed between an air supply pipe and an exhaust pipe of a drying oven, and a dust collection box and a blower can be connected in series to the drying oven via the switching valve. is there. With this configuration, air is circulated inside the waste disposal apparatus when cleaning the drying pot, and there is an effect that dust collection efficiency is improved.

Japanese Patent Application No. 125360/1993 has a configuration in which a high-frequency coil is installed on the lower surface of a drying pot, and high-frequency power is supplied to the high-frequency coil to generate electromagnetic waves. Since high-frequency electromagnetic waves are mixed in the drying pot, the drying pot itself generates heat instead of direct heating, thereby heating the human waste. For this reason, it is possible to quickly heat only the necessary drying kettle, which has the effect of reducing heat loss.

In Japanese Patent Application No. 307135/1993, the drying pot itself is normally upright, the upper part of the drying pot is always open, and the drying pot can be turned over only during cleaning. A heat storage body is accommodated inside the drying pot, and a lid plate that can be closed at the time of a fall is provided at an upper opening. In this configuration,
During the process of evaporating and drying the excrement thrown into the drying oven, the drying oven itself stands still and stands upright. The dust remaining in the opening can be released from the opening. At the time of this dust emission, the lid plate (there are several small holes on its surface) automatically closes the opening of the drying pot,
It prevents the heat storage material from dropping, and allows only dust to be released to the trash dish through a small hole in the lid plate.
The configuration of the human waste treatment apparatus can be simplified.

Further, in Japanese Patent Application No. Hei 5-314445,
The drying pot is supported rotatably, the output of the motor is engaged with the outer periphery of the drying pot, and a plurality of spherical heat storage elements are stored in the drying pot. Three baffle plates are inserted from the lid plate to the inside of the drying pot. In this configuration, unlike the conventional drying pot of the human waste processing apparatus, the drying pot itself rotates around a vertical axis, and the human waste can be heated by the electromagnetic wave from the high frequency coil. The heat storage element accommodated in the drying pot does not rotate with the drying pot due to the baffle plate, but rolls at the bottom of the drying pot, and can stir and heat human waste. In this configuration, there is no need to rotate the stirring blade inside the drying pot,
The height of the entire human waste processing apparatus can be reduced. Further, in the configuration in which the rotating blades are rotated, an excellent effect of eliminating a failure caused by foreign matter (eg, a ballpoint pen, clothing, a clock, etc.) put into the drying pot being entangled with the rotating rotating blades. It has.

Also, in Japanese Patent Application No. 151631/1994, similarly, a drying pot is rotatably supported, the output of the motor is meshed with the outer periphery of the drying pot, and a spherical , And a single baffle plate is inserted from the lid plate located at the upper part of the drying pot toward the inside of the drying pot. Even with this configuration, the drying pot itself rotates about a vertical axis, and the human waste can be heated by the electromagnetic waves from the high-frequency coil. According to the present invention, the baffle plate is formed by one piece fixed to the suction pipe, and since the heat storage body does not fit between the plurality of baffle plates, the heat storage body can be reliably rolled by the rotation of the drying oven. Met.

In these newly proposed human waste processing apparatuses, the excreted human waste can be heated while being sealed in the drying pot, and the human waste can be mixed by rotating the stirring blades and the drying pot. . The temperature of the heated human waste uniformly rises, and most of the moisture, which is a component, evaporates and is released into the atmosphere as water vapor. By this heating and mixing, the rate of evaporation of human waste is increased, and the processing time of human waste can be shortened. In addition, water vapor diffused into the atmosphere is deodorized with a catalyst or the like. This is also preferable from the viewpoint of the above.

It is extremely sanitary to evaporate and diffuse human waste in the sealed evaporating container in this manner, and the operation can be systematized, so that no burden is imposed on the operator in maintenance and the like. is there. However, most of the conventional human waste processing apparatuses have a configuration in which a drying pot is fixed, and the stirring blades are rotated inside the drying pot to mix the human waste. With this mechanism, when foreign matter other than human waste, which cannot be evaporated, is thrown into the drying pot, the rotating stirring blade meshes with the foreign matter, which often causes a failure. For example, a metal ballpoint pen, belt, clothing, or the like may be thrown into the toilet bowl by the user's carelessness. When these foreign substances are thrown into the drying pot, the foreign substances bite between the stirring blade and the drying pot, causing rotation of the stirring blades to stop, and causing a phenomenon that the stirring blades and the drying pot are worn.

Further, if the stirring blades are stored inside the drying pot, the limited internal space of the drying pot is narrowed by these mechanisms, so that the internal space of the drying pot cannot be used effectively. Had become.

To solve such a disadvantage, Japanese Patent Application No.
In Japanese Patent Application No. 314445 and Japanese Patent Application No. 151631, Japanese Patent Application Laid-Open No. HEI 15-1631 discloses a configuration in which the drying pot itself is rotated so that human waste can be mixed without using a stirring blade. But
In this mechanism, the drying kettle must be rotatably supported, and furthermore, the drying kettle must be supported so that it does not move in the vertical direction and the center axis does not deviate. If the rotating drying kettle moves up and down or if the rotating shaft moves in a miso grinding motion, the opening end of the drying kettle will be separated from the lid plate, and the airtightness of the drying kettle will not be maintained.

As described above, in order to restrict the rotational movement of the drying oven, a regulating mechanism (a roller or the like) in two directions, a vertical direction and a rotating direction, is required, and this regulating mechanism must be complicated. It is. In addition, if the regulation mechanism becomes complicated, it takes time and effort to assemble the drying pot, and it takes time to remove the drying pot for inspection and maintenance of the human waste processing apparatus. .

Dust remaining after the human waste is evaporated and dried in the drying oven must be removed in order to continuously treat the human waste, but a suction pipe for cleaning is attached to the drying oven by a predetermined amount. It was difficult to control the insertion by the length. Conventionally, the amount of movement of the suction pipe is detected and controlled so that the suction pipe can be moved up and down by an appropriate length. However, a mechanism for moving the suction pipe and a control mechanism are complicated.

For this reason, the inventor of the present application filed Japanese Patent Application No.
No. 9457 has filed an application for a human waste treatment apparatus in which these disadvantages are improved. In this newly proposed human waste processing apparatus, a rotation holding means is provided at the upper part of the gantry, an evaporation container is hung below the rotation holding means, and an electromagnetic heating means is provided at an interval on the lower surface of the evaporation container. It is characterized by the following. In this proposed configuration, since the evaporating container is suspended and rotated, there is no need to provide any support means on the lower part and the side surface, and the mechanism for holding the evaporating container is extremely simple.

Also, with this configuration, only the evaporation container can be removed from the lower part of the rotation holding means,
It becomes easy to expose the inside of the evaporation container to the outside for periodic inspection and maintenance. It is possible to remove the covering means covering the upper part of the evaporation vessel and observe the inside of the evaporation vessel from above. This is because such a procedure becomes much more complicated.

As described above, in order to put human waste into the evaporating container and to heat and evaporate the human waste together with the evaporating container for processing, a mechanism for stirring the human waste to uniformly increase the temperature of the human waste must be provided. It must not have been. For this stirring, either the stirring blade is rotated at the center of the inside of the evaporation container to stir the waste, or the stirring blade is fixed so as not to rotate and the evaporation container is rotated to stir the waste. That configuration was adopted. Among these, a mechanism for fixing the evaporation container and rotating the stirring blade (for example, Japanese Patent Application No.
No. 90857), the mechanism for pivotally supporting the stirring blade is simplified, and the evaporating vessel can be firmly supported. However, because of the mechanism for rotating the stirring blade near the bottom of the evaporation container, it has been difficult to collect dust remaining in the evaporation container after evaporating the human waste. This is because it is impossible to install a pipe for sucking dust near the bottom of the evaporating vessel by the stirring blade, and it is necessary to suck dust from near the lower end of the rotating shaft that supports the stirring blade.

In a mechanism for rotating the evaporation container and fixing the stirring blade (for example, Japanese Patent Application No. 151631), the evaporation container is provided on the lower surface of a horizontal top plate so as to be rotatable in an airtight manner. A mechanism for suspending a pipe provided with a baffle plate from the top plate to the lower side of the evaporation container has been employed. In this mechanism, when the evaporating container is rotated, the baffle plate relatively rotates near the bottom of the evaporating container, so that the human waste rotating with the evaporating container can be stirred. With this mechanism, the pipe that holds the baffle plate approaches the bottom of the evaporation container and is located off the center of the evaporation container, making it easy to suck dust evenly at the bottom of the evaporation container. This has the feature that the evaporating container can be reliably cleaned.

However, in this mechanism, it is necessary to hold the evaporating container in a rotatable manner, so that the holding mechanism is complicated, and it is difficult to suspend a heavy evaporating container. In addition, since the space between the top plate and the rotating evaporating container must be maintained in an airtight and rotatable manner, there is a disadvantage that the airtightness of the joint portion must be improved. Since the upper end opening of the evaporating vessel is relatively wide, a large-diameter sealing material must be used to maintain the opening rotatably while maintaining airtightness. Had occurred. For this reason, there has been a demand for a mechanism that can stir excrement inside the evaporation container and that can reliably clean dust after drying the excrement. For this reason, Japanese Patent Application No. Hei 7-301
No. 981 proposes a human waste treatment apparatus having a mechanism in which an evaporating container is fixed and a stirring means is rotated in a horizontal direction in the evaporating container. This mechanism does not require a large sealing member because the stirring means rotates, and furthermore, since the shaft rod of the stirring means is assembled in a pipe shape, dust can be sucked by this pipe, and the function of stirring and cleaning can be achieved. Was satisfied.

[0036]

As described above, in the various kinds of human waste processing apparatuses proposed, by storing the human waste in the evaporating container and heating it, the water, which is a major component of the human waste, is evaporated. It can be treated hygienically. However, since the water vapor evaporated by heating the human waste contains elements that cause malodor such as urea and ammonia, it cannot be diffused to the surroundings as it is. The evaporated water vapor was always discharged after the deodorizing treatment. In this deodorizing treatment, steam is brought into contact with the catalyst, and the malodorous element is redox-reduced to change to an odorless state. This treatment makes it possible to seal the evaporating vessel and completely treat the odor without diffusing the odor to the outside.

The catalyst for performing such a deodorizing treatment is formed in a granular shape, and the granular catalyst is protected by a wire mesh or the like, and steam is passed through the gap between the catalyst particles. The reason why the catalyst is formed into a granular shape is that the flow of air can be improved and the contact area between the catalyst and water vapor can be increased. Since the catalyst is configured as described above, when the evaporated water vapor flows between the catalysts, dust and dirt contained in the water vapor flow at the same time in the gap between the catalysts, and the dirt and dirt flow on the surface of the catalyst. This was the cause of adhesion. For this reason, when the human waste treatment apparatus is used for a long period of time, dust and dirt accumulate on the surface of the catalyst particles, causing a deterioration in air fluidity. In addition, since steam cannot directly contact the catalyst, the function of oxidation reduction by the catalyst is also reduced.

For this reason, conventionally, when the human waste treatment apparatus has been used for a certain period of time, it has been necessary to disassemble the catalyst mechanism and wash the granular catalyst with water to remove dust and dirt. In this cleaning maintenance, the cleaning operation is troublesome, and the human waste processing apparatus cannot be used during the operation time, and the use time of the apparatus is limited. For this reason, there has been a demand for the development of a catalyst cleaning mechanism for a human waste treatment apparatus that does not require periodic disassembly of the catalyst mechanism to clean the catalyst, and that can always maintain the function of the catalyst in a normal state.

In view of this situation, the present invention allows air to flow through the catalyst in a direction opposite to the direction in which steam is oxidized and reduced,
Dust, dirt, and the like are automatically removed from the catalyst, so that the catalyst can be maintained in an appropriate state without maintenance, disassembly, and repair even during long-term use. In addition, since the surface of the catalyst can be constantly brought into contact with water vapor, the function of redoxing odorous elements can be exerted at all times. The present invention provides a catalyst cleaning mechanism for a human waste processing apparatus.

The solenoid control circuit 205 does not operate at all (when the urine 162 to be processed is not in the tank 16, the urine processing device 11 does not need to operate).

<Use of urine processing apparatus 11 by user>

As described above, when the power switch 192 is turned on, each mechanism of the urine processing apparatus 11 enters a standby state,
In other words, the user can use the urine treatment device 11 at any time. This waiting urine processing device 11
In order to use, the user stands on the upper surface of the base 12 and excretes urine toward the urinal 15. The excreted urine is received by this morning urinal 15 and flows down the drain pipe 161 to enter the urine 16 in the tank 16.
Stored as 2. The act of excreting urine by the user into the urinal 15 can be performed continuously, and urine of a large number of users can be stored up to an allowable capacity of the tank 16. When urine is excreted toward the urinal 15 in this way, it is stored as urine 162 in the tank 16.

The liquid level of the urine 162 rises as the number of users increases. However, when the urine 162 is stored in the tank 16, its presence is detected by the liquid lower surface sensor 183, and the detection signal by the liquid lower surface sensor 183 is detected. Is transmitted to the drying instruction circuit 197. The drying instruction circuit 197 informs the central processing circuit 191 that the urine 162 has been stored in the tank 16, and the central processing circuit 191 causes the urine 162 to be stored.
To start a cycle for processing.

<< Injection of urine in drying pot 41 >>

First, the central processing circuit 191 transmits a control signal to the pump control circuit 200 and the opening / closing valve control circuit 202 so that the pump control circuit 200 starts the operation of the pump 164 and at the same time, the opening / closing valve 16
Release 6. The urine 162 stored in the tank 16 by the operation of the pump 164 is changed to a suction pipe 163.
The water supply pipe 165, the on-off valve 166,
The water is supplied into the drying pot 41 from the injection hole 53 via the water supply pipe 167. The operation of injecting the urine 162 into the drying pot 41 is performed until either the urine 162 in the tank 16 is completely sucked or the urine 162 of the allowable processing amount is injected into the drying pot 41 satisfies one of the conditions. continue.

The urine 1 stored in the tank 16
When all 62 have been injected into the drying pot 41, the liquid level sensor 183 determines that all the urine 162 has been sucked up, and transmits a detection signal to the drying instruction circuit 197.
Central processing circuit 1 according to the output signal of drying instruction circuit 197
91 determines that the inside of the tank 16 is empty, and the central processing circuit 191 sends the pump 1 via the pump control circuit 200.
The on / off valve 166 is closed by the on / off valve control circuit 202 at the same time. Alternatively, the urine 162 still remains in the tank 16, but when the urine 162 flowing into the drying pot 41 reaches a certain amount, the central processing circuit 1
91 stops the operation of injecting the urine 162 into the drying pot 41.

That is, when the liquid level of the urine injected into the drying pot 41 gradually increases and finally rises to the lower end of the liquid level sensor 181, the urine is moved to the pair of liquid level sensors 181.
Are conducted, and it is detected that the urine of the processing capacity is injected into the drying pot 41 with a limit amount. This liquid level sensor 1
The detection signal of the liquid level of the urine 162 put in by 81 is transmitted to the overflow discriminating circuit 195, which judges that a predetermined amount of urine has been put into the drying pot 41 and sends it to the central processing circuit 191. Transmit the output signal. With this output signal, the central processing circuit 191 stops the operation of the pump 164 via the pump control circuit 200, and at the same time, the open / close valve 166 by the open / close valve control circuit 202.
To close. In this manner, the amount of urine 162 to be injected into the drying pot 41 is detected when urine having a processing capacity or more is injected into the drying pot 41, so that smooth evaporation / drying processing cannot be performed, and This is to prevent urine from overflowing from the upper end. With such control,
Regardless of the amount of urine 162 stored in the tank 16, a certain amount or more of urine is prevented from being injected into the drying pot 41.

<< Restriction on Use of Urinal Processing Device 11 >>

As described above, even when the pump 164 is operated to cause the urine 162 stored in the tank 16 to flow to the drying pot 41 in order to evaporate and dry the urine, the user can operate the small urine irrespective of this processing. The urine is excreted in the toilet 15. The user who uses this urine processing apparatus 11 will continuously use it without knowing the processing capacity of the drying pot 41, and the excreted urine is stored in the tank 16 from the urinal 15, and the liquid level of the urine 162 Will gradually rise. As described above, when the liquid level of the urine 162 rises, the urine 162 eventually overflows the tank 16 beyond the allowable amount that can accommodate the urine 162 in the tank 16. In this case, when the liquid level of the urine 162 reaches the liquid level sensor 184, the liquid level sensor 184 detects that the urine 162 has a liquid level of an allowable height, and sends a detection signal to the use stoppage determination circuit 198. Output.

Then, the use stop determination circuit 198 determines that the urine 162 has been stored in the tank 16 in an amount equal to or larger than the allowable amount, and transmits a determination signal to the central processing circuit 191. A signal is output to the use stop display circuit 193, and the display lamp 194 is turned on by the use stop display circuit 193. This display lamp 1
Reference numeral 94 is installed near the urinal 15 in the urinal processing apparatus 11 described above. When the display lamp 194 is turned on, the user is notified that the urinal processing apparatus 11 has overflown, and the display lamp 194 is turned off. You can be alerted not to use until.

<Start of urine evaporation / drying process>

As described above, the entire amount of urine 162 stored in tank 16 is injected into drying pot 41 by pump 164, or the level of urine injected into drying pot 41 by pump 164 is detected by liquid level sensor 181. When it reaches the point of contact, the central processing circuit 191 stops the operation of the pump 164 and closes the on-off valve 166 at the same time, and then starts the process of evaporating and drying the urine stored in the drying pot 41. In this processing, the central processing circuit 191 follows the steps stored in advance in the motor control circuit 20
1. Heater control circuit 203, solenoid control circuit 20
5 are transmitted to the respective control signals to instruct the evaporating and drying processes. In this process, <heating of the drying pot 41>, <

<< Heating of Drying Kettle 41 >>

When a control signal is input from the central processing circuit 191 to the heater control circuit 203, the heater control circuit 20
Numeral 3 supplies power to the reheater 134 and the high-frequency generation circuit 204, and the high-frequency generation circuit 204 supplies high-frequency power to the high-frequency coil 118. When high-frequency power is supplied to the high-frequency coil 118 housed in the coil container 119, the high-frequency coil 118 generates an electromagnetic wave in a vertical direction, and the high-frequency electromagnetic wave leaks out of the coil container 119 and is stirred at a high frequency. I do. The high-frequency electromagnetic waves leaking from the coil container 119 pass through the bottom of the drying pot 41 approaching the upper surface of the coil container 119, and the electromagnetic waves
1 will be mixed at the bottom.

For this reason, a phenomenon of electromagnetic induction heating occurs due to the mixing of high frequency electromagnetic waves at the bottom of the drying pot 41 (the drying pot 41 is made of a metal material such as iron). The drying pot 41 itself generates heat. At the same time, this electromagnetic wave also mixes with the heat storage body 50 stored in the drying pot 41, and the heat storage body 50 itself also generates heat. Since the drying pot 41 and the heat storage unit 50 generate heat due to the electromagnetic induction heating, the urine stored in the drying pot 41 is heated by the drying pot 41 and the heat storage unit 50, and the temperature rises. When the temperature of the urine rises in this way, the stored urine is finally heated to a temperature at which it boils, and water, which is a major component of the urine, becomes vapor and evaporates from its surface.

<< Reheating by Reheating Heater 134 >>
>

As described above, since the heater control circuit 203 starts supplying power to the reheater 134, the tip of each bar-shaped reheater 134 generates heat at a high temperature. This reheater 13
When 4 generates heat, the internal space of the flow guide hole 132 formed in the heat resistant material 131 shown in FIG. 14 is heated at a high temperature. For this reason, the air flowing in the internal space of the flow guide hole 132 is heated by contacting the heated end of the reheater 134, and flows upward at a high temperature. As described above, the reheating heater 134 heats the air flowing through the flow guide hole 132 by using the catalyst body 140 installed above.
This is because the air is brought into contact with air to cause oxidation and reduction. This is because the catalyst contained in the catalyst body 140 does not exhibit its redox function unless it is maintained at a high temperature.

<< Cooling of Cooling Box 129 >>

Then, the central processing circuit 191 outputs a control signal to the motor control circuit 201 at the same time, and the motor control circuit 201 operates the cooling fans 135 and 136 to cool the cooling box 129. When the cooling fan 135 operates, air is sucked in the direction B in FIGS. 13 and 14, and external cold air flows into the space inside the cooling box 129. When the cooling fan 136 operates, air is discharged in the direction C in FIGS. 13 and 14, and hot air is discharged from the space in the cooling box 129 to the outside. The air in the space inside the cooling box 129 is circulated by these cooling fans 135 and 136 because the temperature of the cooling box 129 rises due to the heat generated by the reheating heater 134. The tip of the reheater 134 generates heat at a high temperature, and the reheater 134 on the back side of the heat-resistant material 131.
This is because the temperature of the electrode side, which is the base portion, becomes high. If the electrode side is not cooled, the reheater 134 will be consumed quickly and the electrode will be melted.

<< Release of Air in Drying Kettle 41 by Exhaust Portion 25 >>

The central processing circuit 191 outputs a control signal to the motor control circuit 201,
1 starts the operation of a motor (not shown) housed inside the blower 145. Then, the blower 145 sucks air from the intake pipe 146 opened on the side surface and discharges the air in the direction of the eject pipe 147, and the discharged air flows through the internal space of the eject pipe 147 and flows from the open end thereof to FIG. Are ejected in the direction E in FIG. When air flows through the eject pipe 147, the core pipe 14 provided in the middle of the
8, the air passes at a high speed, and the outlet 1
Negative pressure is generated around 49. For this reason,
The air inside the core pipe 148 is sucked from the discharge port 149 by the negative pressure, and the air is discharged in the F direction in FIG. The lower end opening of the inner pipe 143 connected to the lower end of the core pipe 148 communicates with the internal space of the catalyst box 139 as shown in FIGS. 14 and 16 (the valve ball 325-a is lowered downward). Therefore, the lower end opening of the inner pipe 143 is open), and the air inside the catalyst box 139 is discharged by discharging the air in the F direction. And the lower part of the catalyst box 139
2. Since it communicates with the inside of the drying pot 41 through the connecting pipe 130 and the exhaust pipe 56,
Is sucked in the order of the exhaust pipe 56, the connecting pipe 130, the flow hole 132, the catalyst box 139, the inner pipe 143, the exhaust pipe 141, and the core pipe 148.

The urine steam and air generated by heating the drying pot 41 are mixed with the air from the blower 145 inside the eject pipe 147 and diffused into the outside air from the open end of the eject pipe 147. Although the air in the drying pot 41 is sucked in the direction of the eject pipe 147, the same amount of air as the discharged amount is newly added to the drying pot 4.
1 must flow. For this reason, the holding plate 3
The surrounding air flows into the drying pot 41 from the air hole 54 opened on the upper surface of the drying tank 41, and the fresh air promotes the oxidation of the urine stored in the drying pot 41.

In such a flow of air, the flow guiding hole 1
When the air flows through the inside of the heater 32, the air comes into contact with the tip of the reheater 134 that is generating heat, is heated, reaches a high temperature, and flows toward the catalyst 140. The water vapor and air evaporated from the drying pot 41 contain elements that cause malodor such as ammonia and bromine, and cannot be released to the outside air as it is. However, when the air from the drying pot 41 passes through the catalyst 140, these malodorous elements come into contact with the catalyst such as platinum and rhodium stored in the catalyst 140, and the malodorous elements are oxidized and reduced to an odorless state. It is transformed and flows into the upper space of the catalyst box 139. The reason why the air flowing through the flow guide hole 132 is heated by the reheating heater 134 is that the catalyst contained in the catalyst body 140 does not exhibit its oxidation-reduction function unless the temperature is high.

<< Rotary Motion of Stirring Unit 28 >>

The central processing circuit 191 outputs a control signal to the motor control circuit 201,
The operation of the motor 108 is started by the
In step 08, the stirring unit 28 is rotated. Motor 10
When power is supplied to the motor 8, the rotational output of the motor 108 is reduced in speed via the gear box 109, and the output shaft 110 at the upper end is rotated at a low speed. Then, the pulley 113 fixed to the output shaft 110 also rotates at the same time, and the pulley 85 is driven via the belt 114 as shown in FIGS. 4 and 6, and the drive fixed to the center thereof by the rotation of the pulley 85. The shaft 66 is rotated in the horizontal direction. (Since the pulley 85 and the drive shaft 66 are engaged with the key 87 as shown in FIGS. 9 and 10, the pulley 85 and the drive shaft 66 are synchronized without any horizontal slip. And rotate). As shown in FIGS. 9 and 10, the drive shaft 66 has upper and lower bearings 74 and 81 for the outer cylinder 6.
6, so that it can rotate smoothly in the horizontal direction. In this way, when the pulley 85 is driven via the belt 114, the rotational force is transmitted to the drive shaft 66 via the key 87 and the pulley 85 is driven.
And the drive shaft 66 are simultaneously rotated in the same direction.

The lower part of the drive shaft 66 is shown in FIGS.
Since the agitating unit 28 is suspended as shown by the arrow, the entire agitating unit 28 rotates in the horizontal direction together with the drive shaft 66. In this rotation operation, a connecting plate 95 is connected to a connecting plate 68 fixed to the lower end of the drive shaft 66, and the connecting plate 95 is formed of a hanging pipe 97, an oblique pipe 98, and a suction pipe 99. Since these pipes are suspended, these pipes rotate in synchronization with the drive shaft 66 inside the drying pot 41. Further, as shown in FIGS. 5 and 6, the suction pipe 99 is
1 and the suction pipe 99 is connected to the drive shaft 6.
It rotates while drawing a circular locus inside the drying pot 41 with the rotation center 6 as the center of rotation. The lower end opening of the suction pipe 99 is rotated with an interval that does not contact the bottom surface of the drying pot 41.

When the suction pipe 99 rotates, the triangular plates 100, 101, the stirring plate 104, and the skirt plate 105 connected to the side surface of the suction pipe 99 are also simultaneously dried.
A circular rotation will occur within 1. This stirring plate 10
4. In the rotation of the skirt plate 105, as shown in FIG.
The stirring plate 104 and the skirt plate 105 rotate in the form while dividing the space of the drying pot 41 into two, and the stirring plate 1
Both end portions of the skirt plate 105 rotate so as not to contact the inner wall of the drying pot 41 at a small interval, and the lower end of the skirt plate 105 rotates so as not to contact the bottom of the drying pot 41 at a small interval. For this reason, as shown in FIG. 5, the stirring plate 104 and the skirt plate 105 rotate so as to stir urine inside the drying pot 41, and at the same time, rotate while pressing the heat storage body 50 stored in the drying pot 41. Will be moved.

<< Stirring of Urine with Heat Storage Body 50 >>

As described above, when the motor 108 is operated, the entire stirring section 28 is rotated by the rotational force, and the heat storage body 50 charged into the drying pot 41 by the stirring plate 104 and the skirt plate 105 is moved to the drying pot 41. It will roll inside. Drying pot 4 with stirring plate 104 and skirt plate 105
In order to stir the urine stored in 1 and simultaneously roll the heat accumulator 50, the urine stored in the drying pot 41 is
4. Stirring is performed by the skirt plate 105 and the heat storage body 50, and the urine is stirred so that the temperature of the whole urine becomes uniform. In this agitation and rolling operation, urine sequentially adheres to the surface of each heat storage element 50, and the heat generated by the heat storage element 50 is transmitted to the urine, respectively, and performs an auxiliary function of raising the temperature of the urine. . In this way, while the urine is being stirred by the heat storage body 50, the temperature at which the heat is generated is transmitted, and the temperature of the entire urine is increased.

In the center of the bottom of the drying pot 41, a projection 43 whose center is raised is formed as shown in the sectional view of FIG. Since the projections 43 are located at the center of the bottom of the drying pot 41, when the plurality of heat storage elements 50 are rolling inside the drying pot 41, the heat storage elements 50 slide down the slopes of the projections 43. In addition, the heat storage body 50 rolls around the drying pot 41 without gathering at the center of the drying pot 41. For this reason,
Even if a plurality of heat storage bodies 50 roll, each heat storage body 5
0 does not collect in the shape of a dumpling at the center of the drying pot 41, but always rolls near the bottom around the drying pot 41, so that the human waste can be surely stirred.

<End of Urine Evaporation / Drying Process by Drying Kettle 41>

As described above, by rotating the stirring unit 28 while heating the drying pot 41 and the heat storage unit 50 by the high-frequency coil 118, the urine stored in the drying pot 41 continues to boil, and the urine constituting the urine is continued. Moisture, a component of the part, will continue to evaporate. If this evaporating operation is continued,
All of the urine stored in the drying pot 41 is evaporated. If all the urine in the drying pot 41 evaporates, it is no longer necessary to continuously heat the drying pot 41 and the heat storage unit 50 with the high-frequency coil 118, and the evaporating and drying process must be completed. The end of this processing is performed by the temperature sensor 180
Can be detected.

When all of the urine stored in the drying pot 41 is dried, the urine has been evaporated until then, so that the drying
Although the temperature of No. 1 was maintained near the boiling point, the temperature of the drying pot 41 rapidly increased because there was no urine to absorb heat. The temperature of the drying pot 41 is determined by the temperature sensor 1
When the urine evaporates and the temperature outside the drying pot 41 rises rapidly, this temperature change is detected by the temperature sensor 180. A temperature change detection signal from the temperature sensor 180 is sent to a temperature discrimination circuit 196.
The temperature discrimination circuit 196 discriminates that all urine in the drying pot 41 has been evaporated. Then, the determination signal from the temperature determination circuit 196 is output to the central processing circuit 191. The central processing circuit 191 stops the evaporation / drying processing and instructs the next cleaning processing.

<< Stopping Heating of Drying Kettle 41 >>

The central processing circuit 191 outputs a signal for stopping the operation to the heater control circuit 203, whereby the heater control circuit 203 stops supplying power to the reheating heater 134 and the high frequency generation circuit 204. For this reason, the reheating heater 134 stops generating heat, and the high-frequency generation circuit 2
At 04, the supply of high-frequency power to the high-frequency coil 118 is stopped, and the heating of the drying oven 41 and the heat storage unit 50 is stopped. The reheater 134 and the high-frequency coil 118
Even if the heating is stopped, the central processing circuit 191 maintains the control signal to the motor control circuit 201, and the motor 108 and the blower 145 continue their operation as before.

<Start of cleaning process>

Next, the central processing circuit 191 starts the cleaning process according to the procedure of the program stored in advance. As described above, when urine is evaporated and dried in the drying pot 41, moisture, which is a major component, evaporates, but organic matter and inorganic substances contained in urine remain as dust. When such dust accumulates in the drying pot 41, the dust adheres to the inner wall and bottom of the drying pot 41 and remains on the drying pot 41. Depending on long-term use, the stirring plate 104, the skirt plate 105, and the heat storage body 50 may remain in the drying pot 41. Unable to rotate, finally urination processing device 1
It will not fulfill the function of (1). Therefore, after the urine evaporating / drying process is completed, a cleaning process must be performed next to remove dust remaining in the drying pot 41.

In this cleaning operation, the central processing circuit 191 outputs a control signal to the motor control circuit 201 to start the operation of the motor 159, and at the same time, outputs a control signal to the on / off valve control circuit 202 to open and close the motor. Valves 171 and 176
Release. When the motor 159 is operated, the fan 174 incorporated in the suction device 157 starts rotating, sucks air in the collection box 152 and discharges the air in the direction of the discharge pipe 158, and discharges it in the direction G in FIG. . Then, the inside of the collection box 152 becomes negative pressure through the filter 156 due to the suction of the air by the fan 174, and the introduction pipe 15
4 sucks air into the collection box 152.

For this reason, the air in the drying pot 41 is sucked from the lower end opening of the suction pipe 99, flows through the suction pipe 99, the oblique pipe 98, and the hanging pipe 97, and then opens at the center of the drive shaft 66. It passes through the ventilation hole 67, passes through the on-off valve 171, the dust suction pipe 172, and the introduction pipe 154, and flows into the garbage bag 155. The air that has passed through the garbage bag 155 flows into the internal space of the collection box 152, passes through the filter 156, and then passes through the suction device 157, the discharge pipe 158, the air supply pipe 175, the on-off valve 176, and the air supply pipe 177. It flows into the upper space of the catalyst box 139 from the discharge pipe 142. The air in the upper space of the catalyst box 139 is sucked from the discharge port 149 by the ejector effect by the exhaust unit 25 as described above, and
The air is released from the opening 47 to the outside air. In this way, a series of air flow paths from the suction pipe 99 to the discharge pipe 142 are formed.

When air is sucked from the lower end opening of the suction pipe 99 and flows in the direction of the collection box 152, the lower end opening of the suction pipe 99 is close to the bottom surface of the drying pot 41. Dust remaining due to non-evaporable organic and inorganic substances remaining at the bottom of the suction pipe 99 is sucked together with air from the lower end opening of the suction pipe 99. The dust sucked together with the air is caused to flow into the garbage bag 155 according to the above-described route, and in the garbage bag 155, the air passes through the film surface, but the dust is caught by the fine mesh of the film surface. You. For this reason, the dust bag 155 separates dust from the air that has flowed in, and acts to pass only clean air into the internal space of the collection box 152. The dust remaining in the drying pot 41 is captured by the dust bag 155. Is done.

At this time, the motor 108 continues to operate after the evaporation / drying process, and the stirring unit 2 is driven via the pulley 113, the belt 114, and the pulley 85.
The whole 8 rotates in a circular locus like a miso rubbing motion in the drying pot 41. For this reason, the lower end opening of the suction pipe 99 rotates circularly at the bottom of the drying pot 41, and sucks up the dust accumulated at the bottom of the drying pot 41 uniformly. Further, when the stirring unit 28 rotates, the stirring plate 10 is rotated.
4. Since the skirt plate 105 rotates at the same time and the heat storage body 50 is rolled at the bottom of the drying pot 41, the heat storage body 50
As a result, the dust accumulated at the bottom of the drying oven 41 is peeled off and finely crushed, and the dust accumulated at the bottom of the drying oven 41 is peeled and finely crushed so as to be easily sucked together with air.

In this way, the dust sucked up from the lower end opening of the suction pipe 99 is captured by the garbage bag 155,
The clean air that has passed through the membrane surface of the garbage bag 155 passes through the filter 156 and is discharged to the upper opening of the catalyst box 139 through the above-described path. In this air flow, the valve opens inside the on-off valve 176, and the air supply pipe 1
Since the flow of air to the air supply pipe 177 is allowed from 75, air flows smoothly in this flow direction. Then, the clean air discharged into the upper space of the catalyst box 139 is suctioned at the discharge port 149. (The blower 145 continues to operate following the evaporating / drying process and continues to operate. ), Flows in the order of the exhaust pipe 141 and the core pipe 148, is mixed with the air flowing through the eject pipe 147, and is discharged from the open end of the eject pipe 147 to the outside air.

<Stop of cleaning process>

As described above, when the cleaning process by suctioning the dust accumulated in the drying pot 41 is performed for a predetermined time, the dust stored in the bottom of the drying pot 41 becomes dusty. It is captured by the bag 155 and the cleaning process is completed. Then, the urine disposal device 11 must automatically stop the cleaning process and return to the initial state. This is because the urine 162 that needs to be processed next still remains in the tank 16.

In the stop of the cleaning process, if a predetermined time has elapsed since the start of the cleaning process according to a program stored in the central processing circuit 191, the central processing circuit 191 makes a self-determination. Outputs stop signal.
Therefore, the central processing circuit 191 is connected to the motor control circuit 20.
1 to output a control signal, stop the operation of the motor 159, stop the suction of air by the fan 174, and stop the suction of air from the drying pot 41 by the suction pipe 99. At the same time, the central processing circuit 191
2 also outputs a control signal, and the ventilation hole 67 and the dust suction pipe 17 are output.
2 is closed. Thus, the air flow path from the lower end opening of the suction pipe 99 to the distal end opening of the discharge pipe 142 is closed, the air and dust do not flow, and the cleaning process is stopped.

The above-described series of processing operations is continuously performed even if the power switch 192 is turned off halfway. This is because once the urine is put into the drying pot 41, one processing cycle must be completed and all the urine in the drying pot 41 must be evaporated unless a part of the apparatus breaks down. . If the power switch 192 is turned off due to carelessness of a worker during the processing and the <evaporation / drying processing> is stopped, the urine remains in the drying pot 41 as it is. This is inconvenient.

<Cleaning of Catalyst 140>

By such an operation according to the program stored in the central processing circuit 191, the urine stored in the drying pot 41 is evaporated and dried, and after the deodorizing process is performed, the inside of the drying pot 41 is cleaned. Processing is performed, and a series of operations ends. By sequentially performing this cycle, urine in the tank 16 is sequentially processed. However, in such a urine evaporating / drying process, the flow path of the steam that is heated and evaporated from the inside of the drying pot 41 flows in the direction L as shown in FIG. Of the catalyst box 140 through the catalyst 140
Flows into the interior space. Then, as described above, the air passes through the inner pipe 143 and the core pipe 148, is sucked by the ejector effect generated by the negative pressure of the air flowing at high speed through the intake pipe 147, and is diffused in the direction E in FIG.

When the water vapor flows in the direction L in FIG. 22, the water vapor evaporating from the urine contains dust and dirt, and flows in the direction L simultaneously with the water vapor.
The water vapor evaporated from the inside of the drying pot 41 always passes through the inside of the reheating box 128 and comes into contact with the surface of the catalyst 140 to be oxidized and reduced. For this reason, dust and dirt contained in the air flowing in the L direction together with the evaporated water vapor pass through the inside of the catalyst body 140 and form a surface of the catalyst particles forming the catalyst body 140 in a granular form. And comes into contact with the catalyst particles. In the long-term use of the drying pot 41, it is inevitable that dust and dust flowing along with the steam adhere to the surface of the catalyst body 140. If dust or dirt adheres to the catalyst body 140, the function as a catalyst is reduced, and the ability to oxidize and reduce malodorous elements is reduced. Therefore, the catalyst body 14 is periodically removed, not every cycle of evaporating and drying the urine stored in the drying pot 41.
The dust and debris adhering to the surface of the zero must be cleaned. If the urine is evaporated and dried while the dust and dirt are attached to the surface of the catalyst 140, the water vapor containing the odor cannot come into contact with the surface of the catalyst 140, and the odor is not oxidized and reduced. This is because it is diffused in the direction E in FIG. 22 while containing odors, which causes an unpleasant odor outside the human waste processing apparatus.

<< Time of Cleaning Process of Catalyst 140 >>

When a series of processing cycles for injecting urine into the drying pot 41, heating, evaporating, and cleaning is completed, the central processing circuit 191 determines whether or not to clean the catalyst body 140. As a criterion for this determination, the determination is made based on how much the urine processing device 11 has been used. That is, a timer circuit is provided inside the central processing circuit 191, and the timer circuit accumulates the total time of the processing cycle using the drying pot 41. Therefore, if a predetermined time (for example, a period of 24 hours or one week) set in the central processing circuit 191 is accumulated, the timer circuit housed in the central processing circuit 191 cleans the catalyst 140. You will judge when it is necessary. If the time accumulated by the timer circuit in the central processing circuit 191 does not reach the set time, the cleaning process of the catalyst 140 is not performed, and the process proceeds to the next process. Although it has been determined, the number of urine processing cycles by the drying pot 41 may be counted).

<< Switching of Flow Path >>

Thus, the total time using the drying pot 41 is integrated by the timer circuit of the central processing circuit 191.
When the time reaches a preset time, the central processing circuit 1
91 starts the cleaning process of the catalyst body 140. In this cleaning process, the air flow path in the urine treatment device 11 is switched.

First, the central processing circuit 191 outputs a control signal to the on-off valve control circuit 202, and outputs the on-off valves 171 and 176.
Release. For this reason, the air flow path is switched, and the on-off valve 171 closed in FIG.
The suspension pipe 97 and the dust suction pipe 172 conduct, the open / close valve 176 is opened, and the air supply pipe 175 and the air supply pipe 1
77 is conducted.

At the same time, since the central processing circuit 191 transmits a control signal to the solenoid control circuit 205, the solenoid control circuit 205 supplies an operating current to the solenoid coil 270. When an operating current flows through the solenoid coil 270, the coil housed therein generates a magnetic field, and the iron core 278 is attracted into the solenoid coil 270 by the lines of magnetic force. For this reason, in FIGS. 16 and 17, since the connecting body 279 fixed to the iron core 278 is pulled down, the joint body 296 connected to the connecting body 279 by the bolt 303 is similarly pulled down. Then, the bolt 30 is attached to the upper end of the joint body 296.
The seesaw body 285 connected by 1 is swung counterclockwise in FIG. 16 around the bolt 293 as the center of rotation. Bolt 30 spanned between connectors 243 and 244
A spring 312 extends between the bolt 7 and the bolt 309 fixed to the seesaw body 285, and the seesaw body 285 is constantly urged clockwise in FIG. When the seesaw body 285 rotates counterclockwise about the bolt 293, the seesaw body 285 rotates counter to the elastic force of the spring 312.

Since the iron core 278 is attracted by the magnetic force in this manner, the seesaw body 285 rotates counterclockwise in FIG.
5, the upper end of the operating rod 315 connected to the tip of FIG.
It will be lifted upward in FIG. When the operating rod 315 moves upward while passing through the openings 242 and 150, the valve ball 325 fixed to the lower end of the operating rod 315 also moves upward, and the valve ball 325 comes into close contact with the lower end of the inner pipe 143. . This spherical valve ball 32
When the outer periphery of 5 comes into contact with the lower end opening of the inner pipe 143, the opening of the inner pipe 143 is closed by the valve ball 325. When an operating current is supplied to the solenoid coil 270 by this interlock, the valve ball 325 closes the opening of the inner pipe 143 and the valve ball 325 moves to the position shown by the solid line in FIG. When the operating current is continuously supplied, the operation current is continuously maintained. Further, as shown in FIGS. 14 and 15, air is blown from the blower 145 to the intake pipe 147.
Since the air is blown in the direction, a negative pressure is generated by the ejector effect in the core pipe 148 opened inside the intake pipe 147, and the valve ball 325 in contact with the inner pipe 143 is sucked.

Thus, when the outer periphery of the valve ball 325 comes into contact with the lower end opening of the inner pipe 143, the inner pipe 14
3 is closed, and the communication between the inner space of the catalyst box 139 and the core pipe 148 is cut off. Then, the catalyst box 139
Has no portion communicating with the outside and is shut off from the outside, so that the air in the catalyst box 139 cannot flow out to the outside. At the same time, air from the outside
9 and the catalyst box 139 and the drying kettle 4
1 is a closed space from the outside.

<< Air Flow >>

When the flow paths are switched in this way, the central processing circuit 191 outputs a control signal to the motor control circuit 201, and the motor control circuit 201 operates the motor 159 to activate the fan 174 built in the suction device 157. Rotate. When the fan 174 is rotated, the collection box 152 is rotated.
The air inside is sucked and discharged in the direction of the discharge pipe 158, and discharged in the direction G in FIG. Then, the inside of the collection box 152 becomes negative pressure through the filter 156 by the suction of the air by the fan 174, and the air is sucked into the collection box 152 from the introduction pipe 154.

For this reason, the air in the drying pot 41 is sucked from the lower end opening of the suction pipe 99, flows through the suction pipe 99, the oblique pipe 98, and the hanging pipe 97, and then opens at the center of the drive shaft 66. It passes through the ventilation hole 67, passes through the on-off valve 171, the dust suction pipe 172, and the introduction pipe 154, and flows into the garbage bag 155. The air that has passed through the garbage bag 155 flows into the internal space of the collection box 152, passes through the filter 156, and then passes through the suction device 157, the discharge pipe 158, the air supply pipe 175, the on-off valve 176, and the air supply pipe 177. It flows into the upper space of the catalyst box 139 from the discharge pipe 142. However, since the core pipe 148 opened at the upper part of the catalyst box 139 is closed by the valve ball 325, the core pipe 148 does not flow outside through the core pipe 148 and flows toward the reheating box 128. As shown in FIG. 23, the air in the drying pot 41 is sucked from the lower end opening of the suction pipe 99 and flows in the M direction, and flows through the oblique pipe 98 and the suspension pipe 97. Then, it passes through the open / close valve 171, flows inside the dust suction pipe 172 in the N direction in FIG. 23, and flows into the garbage bag 155 inside the collection box 152. This garbage bag 155
Has a membrane surface through which air can pass, so that the air passes through the surface of the garbage bag 155, passes through the filter 156, and is sucked by the fan 174.

Further, the air flows inside the air supply pipe 175, passes through the open / close valve 176, and then flows through the air supply pipe 177 in the direction P in FIG. This flowing air is finally discharged from the discharge pipe 14 shown in FIG.
2 is ejected into the inside of the catalyst box 139 from the opening at the front end. Since the tip opening of this discharge pipe 142 is slightly downward as shown in FIG.
The air blown out from the tip of the second 2 is blown to the catalyst body 140 rather than to the internal space of the catalyst box 139. Due to the flow of the air blown to the catalyst body 140, dust and dirt adhering to the surface of the catalyst particles housed in the catalyst body 140 are knocked down, and the reheating box 12
Drop in the direction of 8. The air containing dust and dirt flows in the direction Q in FIG. 23 and moves into the drying pot 41. In this manner, air circulates in the order of M, N, P, and Q in FIG.
A series of up to two air channels is formed

<< Dust Capture and Recovery >>

As described above, the air circulates in the flow path closed from the outside, so that dust and dirt adhering to the catalyst body 140 are knocked down by the air flow and fall.
The drying pot 41 is transported after falling down the internal space of the reheating box 128. The air containing dust and debris that has flowed into the drying pot 41 is sucked through the lower end opening of the suction pipe 99, and FIG.
In the M direction, the oblique pipe 98 and the hanging pipe 9
7. After passing through the on-off valve 171, the inside of the dust suction pipe 172 is
3 flows in the N direction. Then, the garbage bag 155 flows into the space inside the garbage bag 155 from the end of the dust-absorbing pipe 172. The garbage bag 155 is made of a material that allows air to pass therethrough but captures dust and dirt on its film surface. Dust and dirt are captured on the film surface 155. Then, after the clean air passes through the filter 156, the air supply pipe 175,
The gas passes through the on-off valve 176 and the air supply pipe 177, flows in the P direction in FIG. 23, and is further ejected toward the catalyst 140 from the distal end opening of the discharge pipe 142 at the distal end of the air supply pipe 177. . Dust and dust adhering to the catalyst body 140 are removed by the circulation of the airflow, and the removed dust is automatically captured by the dust bag 155.

<< Return of Cycle to Evaporation / Drying Process >>

When the cleaning operation is performed for a predetermined time after the central processing circuit 191 determines the cleaning processing of the catalyst body 140, the cleaning operation is returned to the original state, and the cycle of heating and evaporating urine is started. Or, shift to the stop state.
In this return operation, the central processing circuit 191 stops the control signal to the solenoid control circuit 205 and stops the supply of the operating current to the solenoid coil 270. Then, since the solenoid coil 270 stops generating magnetic force, the solenoid coil 270 stops attracting the iron core 278. As described above, the bolt 29 fixed to the seesaw body 285
A spring 312 is locked to 3, and the seesaw body 285 is urged clockwise in FIG. 16 with the bolt 293 as the center of rotation due to the elasticity of the spring 312. For this reason, the iron core 27 by the solenoid coil 270 is used.
After the suction force of the spring 8 is released, the seesaw body 285 cannot be held at the position shown by the solid line in FIG.
Due to the elastic force of No. 12, it is rotated clockwise, and is swung to the position of the seesaw body 285-a indicated by a chain line in FIG. When the seesaw body 285 is returned from the position shown by the solid line to the seesaw body 285-a shown by the chain line, the seesaw body 2
The connecting body 279 and the iron core 278 connected to the lower end of the 85 (the left side in FIG. 16) via the joint body 296 are pulled up.

When the seesaw body 285 is swung by the spring 312 and returns to the position of the seesaw body 285-a, the operating rod 315 connected to the tip of the seesaw body 285-a is pushed down. Become. The operating rod 315 is pushed down through the passages 242 and 150, and at the same time, the valve ball 325 fixed to the operating rod 315 is also moved downward. Therefore, the valve ball 32
5 is lowered from the position shown by the solid line to the position of the valve ball 325-a shown by the chain line, and the outer periphery of the valve ball 325-a is separated from the lower end opening of the inner pipe 143. Thus, the outer circumference of the valve ball 325-a and the inner pipe 143
A gap is formed between the catalyst box 139 and the inner pipe 143 so that air can flow between the catalyst box 139 and the inner pipe 143. Air remaining in the intake pipe 14
7 is sucked by the air flowing at a high speed and is discharged to the outside.

Then, the central processing circuit 191 transmits a control signal to the motor control circuit 201 and the motor control circuit 201
1 to cut off the supply of driving power to the motor 159,
The rotation of the fan 174 connected to the motor 159 is stopped. Thus, the circulation of the air shown in FIG. 23 is stopped. Further, the central processing circuit 191 includes the on-off valve control circuit 2
A control signal is transmitted to the ON / OFF valve 02 and the ON / OFF valves 166 and 176 are closed by the ON / OFF valve control circuit 202. Thereby, the internal space of the drying pot 41 and the internal space of the collection box 152 are
1, the air stops flowing from the drying pot 41 to the collection box 152. Further, since the on-off valve 176 is closed, the communication between the internal space of the collection box 152 and the internal space of the catalyst box 139 is cut off, and the air does not flow from the collection box 152 to the opening at the tip of the flange 42. By such switching of the flow path, the state of the flow path shown in FIG. 23 is returned to the state of the flow path shown in FIG.
When a part of the flow path is closed and the inner pipe 143 is opened, the state returns to a state where the urine evaporating / drying process can be performed again, and the next operation is performed.

<Do you want to start the next processing cycle?>

In this way, if a series of processing of <cleaning processing>, <stopping of cleaning processing>, and <cleaning of catalyst body 140> is performed after <evaporation / drying processing>, It is determined whether to stop the operation of the processing device 11 or to shift to the next processing cycle. The operation of the urine processing apparatus 11 is stopped based on whether the power switch 192 is turned off. If the processing is progressing up to this point and the power switch 192 is turned off, the central processing circuit 191 stops all operations of the urine processing device 11. However, even if the processing cycle is in progress, if the power switch 192 is turned on, the processing cycle returns to the <evaporation / drying processing> described above, and the urine is again heated and evaporated. .

<Process of evaporating and drying urine again>

The condition that the above-mentioned <Stop of the cleaning process> has been completed and the power switch 192 has been turned on, and the liquid level sensor 183 is still in the tank 16
When it is detected that 2 remains, the central processing circuit 191 starts the <evaporation / drying process> of urine again, and continues the next processing cycle. In this process, as described above, the central processing circuit 191 outputs control signals to the pump control circuit 200, the on-off valve control circuit 202, and the heater control circuit 203, and a predetermined amount of urine 162 is dried in the same manner as described above. The urine is injected into the drying tank 41 and the urine is evaporated and dried in the drying pot 41. In the same manner as described above, the cycle of this processing is the cycle of <evaporation / drying processing>, <cleaning processing>, <stopping of cleaning processing>, <judgment of stopping processing cycle>. Unless 192 is turned off, if the urine 162 is stored in the tank 16, the operation is continuously repeated until the urine 162 in the tank 16 is completely processed.

<Return to Standby State>

However, if the condition is that the <stop of cleaning process> or <cleaning of the catalyst body 140> has been completed and the power switch 192 is on, and the tank 16 is empty, the processing cycle starts. Does not shift, and the urine processing apparatus 11 shifts to a standby state. That is, the liquid lower surface sensor 183
When it is detected that the urine 162 in the tank 16 is not stored, the tank 16
Is transmitted to the drying instruction circuit 197, and a signal indicating that the tank 16 is empty is transmitted to the central processing circuit 191 in the drying instruction circuit 197. Then, the central processing circuit 19
1 does not shift to the cycle for processing urine, but stops the urine processing apparatus 11 as a whole and waits. This standby state is the same as the start of the process at the beginning.

Therefore, the central processing circuit 191 outputs a control signal to the motor control circuit 201 to stop the operation of the motor 108. Then, the stirring unit 28 that has been rotated in the drying pot 41 is stopped by the driving force of the motor 108, and the rotation of the stirring plate 104, the skirt plate 105, and the heat storage unit 50 is stopped (the heater control circuit 203 sets the < Since the supply of power to the reheater 134 and the high-frequency generation circuit 204 is stopped at the time of the cleaning process, the reheater 134 does not generate heat.
Since no high-frequency power is supplied to 18, the drying pot 41 is not heated.) This waiting state is continued until the user excretes urine to the urinal 15 and the urine 162 is stored in the tank 16. When the power switch 192 is turned off in this standby state, the urine disposal device 11 stops all of its functions.

<Stopping operation of urine processing device 11>

The operation of the urine processing apparatus 11 can be stopped by turning off the power switch 192. For example, there is a case where it is not necessary to process urine at night at a temporary setting site or a venue for entertainment, or the urine processing apparatus 11 is stored in a warehouse or the like from an installation location. In such a case, the operation of the entire urine processing apparatus 11 is stopped by the administrator or the worker manually turning off the power switch 192. However, as described above, even if the power switch 192 is turned off while a processing cycle such as <evaporation / drying processing> or <cleaning processing> continues, the processing in that cycle continues and is performed once. The operation does not stop until the processing cycle is completed. When the processing cycle is completed, the operation of the urine processing apparatus 11 stops.

<Flowchart showing processing cycle>

As described above, according to the first aspect of the present invention, a stirrer is accommodated in a container for accommodating sewage, and the sewage and the heat accumulator are rotated by rotating the agitator. Can be rotated to stir. For this reason, by heating the container with the heating means, the moisture, which is a major component of the stored human waste, can be evaporated and sanitarily treated, and the heat can be removed by rotating the regenerator by the stirring means. And the evaporation can be carried out smoothly. Then, the element causing the bad odor contained in the evaporated water vapor is redox-reduced by coming into contact with the catalyst of the deodorizing means and is discharged in an odorless state, so that the bad odor is not diffused to the surroundings.

Further, since the container can be fixed compared with the conventional human waste processing apparatus in which the container storing the human waste is rotated and the human waste is stirred, the container itself can be held firmly. Further, since there is no need to rotate the container, there is no need to provide a structure for maintaining airtightness at the joint surface due to the rotation, so that the structure is simplified and the manufacturing cost is reduced.

Further, between the space of the container and the deodorizing means,
A looped air flow path including a suction path, a dust collection means, a suction means, and an exhaust path is formed, and the air can be circulated at a high speed along this path. Then, the air normally flows out of the container through the catalyst in the deodorizing means, but when the suction means operates, the air flows at a high speed opposite to the flowing direction. For this reason, dust and dirt adhering to the surface of the catalyst are blown off by the air flow, flow in the order of the container and the suction path, and are captured by the dust collecting means. Therefore, without disassembling the deodorizing means, the catalyst can be cleaned by flowing air in the direction opposite to the normal flow direction of the air, and the dust and dirt separated by the cleaning can be collected. Can be done

According to the invention of claim 2 of the present application, the stirring means rotatably held inside the container has a hollow pipe shape inside, and this stirring means is arranged downward from the upper part of the container. The lower end opening of the pipe-shaped stirring means is located close to the bottom of the container. Since the suction path is connected to the opening at the upper end of the stirring means, as described above, when air is caused to flow by the suction means, dust and debris collected at the bottom of the container are removed by a pipe-shaped stirring means. Can be sucked up from the lower end opening of the cover and dust and dust can be reliably collected. Also, since the stirring means rotates close to the bottom of the container, the bottom of the container can be suctioned evenly,
Dust and dirt can be reliably collected.

According to the invention of claim 3 of the present application, the downstream side of the deodorizing means communicates with the outside, but the discharge side can be selectively opened and closed by the valve mechanism. For this reason, the exhaust side can be opened and the steam can be discharged to the outside as it is when the human waste accommodated in the container is evaporated, and the exhaust side can be closed when cleaning the catalyst. When performing catalyst cleaning processing, a closed circulation path can be formed inside the device to prevent high-speed air flow from flowing out, so that dust and debris are not diffused outside. Can be recovered in a closed circuit.

According to the invention of claim 4 of the present application, the exhaust side of the deodorizing means can be opened and closed by the valve mechanism, and the on-off valve is interposed in each of the suction path and the exhaust path. By opening the valve mechanism and closing both open / close valves during normal human waste evaporation processing, the steam does not flow from the suction path or the exhaust path toward the dust collecting means. Further, in the process of cleaning the catalyst, by closing the valve mechanism and opening both open / close valves, the suction path, the dust collection means, the suction means,
A closed air flow path is formed in the exhaust path and the forward path of the deodorizing means, and the air can be circulated efficiently, and
Dust and dirt can be collected without being diffused to the outside.

According to the invention of claim 5 of the present application, the valve mechanism is composed of a spherical valve body and an exhaust port on the exhaust side of the deodorizing means, and air is determined depending on whether the valve element contacts the exhaust port. To open and close the flow path. Because of this configuration, the valve configuration is simplified, and even if it is provided on the exhaust side of the deodorizing means through which high-temperature air flows, there is no seizure or deformation unlike a normal valve, and the air flow path is reliably ensured. Can be opened and shielded.

According to the invention of claim 6 of the present application, the valve element constituting the valve mechanism is moved up and down by the solenoid, so that the operation only needs to be controlled in one direction, and the mechanism is simple, so that the occurrence of a failure may occur. Less. In addition, the control signal can be switched only by supplying a current to the solenoid, which facilitates control.

According to the invention of claim 7 of the present application, the exhaust path is extended downstream of the catalyst in the internal space of the deodorizing means, and its end is formed as a nozzle, and the direction of the nozzle is the direction of the catalyst. Facing the top of Therefore, the air ejected from the exhaust passage flows at a higher speed than the nozzle and is ejected to the upper surface of the catalyst, so that dust and dirt attached to the catalyst can be efficiently removed.
