Description

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 a purification treatment facility, in transportation facilities such as ships and trains, and in tunnels that are closed from the surroundings and in which vacuum cars cannot enter. The present invention relates to a device, and more particularly, to a human waste treatment device capable of effectively stirring human waste.

[0002]

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 sterilizing and deodorizing by adding 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 ejected to the 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 a basic one, and the inventor of the present invention successively proposes 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.
The dust remaining in the drying pot after drying the human waste is sucked and collected together with the air, and the dust can be separated from the air by the 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 of the second year of the present invention, a storage tank for storing urine collected by a urinal is provided, and the storage tank and the urinal are connected by an injection jet 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.

And, in Japanese Patent Application No. Hei 3 189280,
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 evaporation process of the human waste, and the flow of the air can be made 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.

Further, Japanese Patent Application No. 189281 of Japanese Patent Application No. 189281 is an improvement of Japanese Patent Application No. 189280 of Japanese Patent Application No. 198328. Is a structure in which the negative pressure side of the ejector is connected and a 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. Hei 3265265, a dust collecting box is connected to an exhaust pipe of a drying pot, and a dust bag made of paper, cloth or the like is stored in the dust collecting box. With this configuration, air containing dust is allowed to flow into the dust bag when cleaning the drying pot, and only the air passes through the dust bag to separate the dust. Compared with a cyclone type dust collector, it has the effect of reliably separating dust.

And, in Japanese Patent Application No. 031170,
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 in the drying pot is evaporated and dried by the heat of the burner, and during this process, the human waste can be stirred by the heat storage body by rocking the drying pot, and the drying pot is rotated after drying. Therefore, dust can be dropped 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 housed inside the drying pot, and a lid plate that can close the upper opening when it falls is provided. 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.

Furthermore, in Japanese Patent Application No. 314445 of the fifth year,
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, in most of the conventional human waste treating apparatuses, a drying pot is fixed and the stirring blade is 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 drawbacks 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.

[0033]

As described above, in order to put the excrement into the evaporation container and heat the excrement together with the evaporation container to evaporate and treat the excrement, the excrement is stirred to uniformly increase the temperature of the excrement. It was necessary to provide a mechanism for doing so. 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. Within this,
A mechanism for fixing the evaporation vessel and rotating the stirring blade (for example, Japanese Patent Application No. 190857/1988) simplifies the mechanism for pivotally supporting the stirring blade, and has a characteristic that the evaporation vessel can be firmly supported. Was. 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, with this mechanism, the evaporation container must be held so that it can rotate, and the mechanism for holding the evaporation container is complicated, making it difficult to suspend a heavy evaporation 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.

As described above, each of the mechanism for rotating the stirring blade to stir the excrement and the mechanism for rotating the evaporation container to stir the excrement has its respective drawbacks. For this reason,
It has been desired to develop a mechanism capable of stirring human waste inside the evaporation container and reliably cleaning dust after the human waste is dried. Moreover, a mechanism that satisfies the contradictory functions of agitation and cleaning, has a simple assembling mechanism, and can be manufactured at low cost has been desired.

Furthermore, the upper end of a skirt plate 115 formed by bending a thin steel plate into a taper shape is fixed to the arc-shaped lower side of the stirring plate 114. It has a shape similar to that of a shroud. 6, the radius of curvature of the stirring plate 114 is set to be larger than the radius of curvature of the inner periphery of the drying pot 51, and the length of both ends of the stirring plate 114 is slightly smaller than the inner diameter of the drying pot 51. It is set to the extent that it becomes smaller. For this reason, in the stirring plate 114 fixed to the triangular plates 110 and 111, the straight line connecting both ends of the stirring plate 114 passes near the center of the drying pot 51 (see FIG. 6), and the stirring plate 1
14 and the skirt plate 115 are arranged so that the inner space of the drying pot 51 is divided into two.

[Structure in which the stirring section 28 is connected to the bearing section 24]

The stirring portion 28 thus constructed is connected to the lower portion of the bearing portion 24 so as to be suspended, as shown in FIGS.

The air can flow from the lower end opening of the suction pipe 109 to the upper end opening of the ventilation hole 77.

The plan view of the agitating section 28 suspended from the bearing section 24 is shown in FIG. 6, and both ends of the agitating plate 114 are spaced apart from the inner wall of the drying pot 51 by a distance. The center of the circular stirring plate 114 is separated from the inner wall of the drying pot 51 by a distance of about 1/4 of the inner diameter of the drying pot 51. 7 and 9 show the side surface of the stirring unit 28 suspended from the bearing unit 24.
The lower side of the skirt plate 115 is located slightly upward so as not to contact the bottom surface of the drying pot 51, and is set so that the skirt plate 115 does not contact the bottom surface of the drying pot 51. As shown in FIG. 7, the axis of the suction pipe 109 is positioned vertically, and the lower end opening of the suction pipe 109 is positioned slightly above the bottom surface of the drying pot 51. Then, in a state where the agitating unit 28 is hung by the bearing unit 24, the oblique pipe 108 is positioned obliquely downward to the hanging pipe 107, and the suction pipe 109 approaches the inner wall of the drying pot 51. Be placed. Therefore, the drive shaft 76
When the is rotated, the suction pipe 109 is
7 rotates in the inner space of the drying pot 51 so as to draw a circle having a radius defined by the distance between the axis of 7 and the axis of the suction pipe 109.

[Structure of Drive Unit 22]

Next, the structure of the drive unit 22 will be described with reference to FIGS. 5, 7, and 8. A main member of the drive unit 22 is composed of a motor 118 having a cylindrical shape, and a rectangular gearbox 119 for reducing the rotation speed and outputting the rotation speed is integrally connected to an upper portion of the motor 118. . At the center of the upper surface of the gear box 119, an output shaft 120 for outputting a reduced rotational force is vertically projected. Further, a square motor hole 42 is opened on the front side (the right rear side in FIGS. 5 and 8) of the holding plate 41 described above. The tool 121 is fixed by screws. The motor fixture 121 has a length slightly longer than the opening width of the motor hole 42, a cross-sectional shape of "U", and a foot portion extending horizontally at both ends. When the foot portions formed at both ends of the motor fixing tool 121 are brought into close contact with the upper surface of the holding plate 41, and each foot portion is fixed with a screw, the motor fixing tool 121 is fixed so as to close the motor hole 42. A circular opening 122 is formed in the center of the motor fixture 121, and the output shaft 120 is inserted above the opening 122 below,
When the upper surface of the gear box 119 is brought into close contact with the lower surface of the holding plate 41, the gear box 119 and the motor fixture 121 are attached.
Are connected by screws. Thus, the motor 118 and the gear box 119 can be fixed to the motor fixture 121.

When the gearbox 119 is fixed to the motor fixing member 121 in this manner, the output shaft 120 vertically projects from the upper surface of the motor fixing member 121. A pulley 123 is fitted into the output shaft 120 and the pulley 1
23 is set at the same height as the pulley 95 fixed to the drive shaft 76 (see FIG. 7). Then, an endless belt 124 made of rubber or the like is wound around the outer circumferences of the pulleys 95 and 123 (see FIGS. 5 and 7).
See FIG. 8). Although not shown in FIGS. 5 and 8, as shown in FIG. 7, a screw plate 125 protrudes from the upper surface of the holding plate 41 at a position close to the motor hole 42. A tension bolt 126 that can move in the horizontal direction is screwed into 125. The tip of the tension bolt 126 is in contact with the side surface of the motor fixture 121, and by turning the tension bolt 126, the motor fixture 121 can be moved horizontally in the horizontal direction in FIG. This tension bolt 126
By moving the motor fixture 121 horizontally, the distance between the center axes of the pulley 95 and the pulley 123 can be changed, and the tension of the belt 124 can be finely adjusted. By adjusting the tension of the belt 124, the rotational force from the motor 118 can be smoothly transmitted to the drive shaft 76.

[Structure of Heating Unit 23]

The outer shape of the heating unit 23 described above is shown in FIGS.
This is shown by FIGS. The outer shape of the heating unit 23 is a flat box shape, and as shown in FIG.
5 is mounted on the upper surface of a pair of horizontal angles 46 held by the pair. The heating unit 23 mixes high-frequency electromagnetic waves into the drying pot 51 and the heat storage unit 60 by a high-frequency coil 128 serving as electromagnetic heating means housed therein, thereby generating eddy current loss in the drying pot 51 and the heat storage unit 60. Can generate heat. The heating unit 23 is assembled as a unit for generating electromagnetic waves, and the internal structure of the heating unit 23 will be described in detail with reference to FIG.

The outer shell of the heating section 23 is composed of a coil container 129 having a hollow box shape inside.
It is composed of a lid plate 131 that closes the upper opening of 30. The box 130 is made of a thin metal plate and has a square bottom, and is formed in a square shape by standing up four sides of the bottom. The lid plate 131 is formed by cutting a thin metal plate into a square shape, and its planar shape is set to be slightly larger than the opening of the box 130. Therefore, when the cover plate 131 is put on the upper opening of the box body 130, the four corners of the cover plate 131 project horizontally,
The upper part of the coil container 129 projects right and left.
The lower surface of the lid plate 131 is brought into close contact with the opening of the box 130,
A single coil container 129 is assembled by screwing the two or joining them together by electric welding.
Reference numeral 9 denotes a configuration in which the inside is hollow and closed from the outside.

A high-frequency coil 128 having a flat cylindrical shape for generating electromagnetic waves is housed in the center of the hollow inside of the coil container 129 as shown in FIG. Perimeter and coil container 1
29 is fixed with some gaps so as not to contact the inner peripheral surface. A pair of power lines 132 for power supply are connected to the high-frequency coil 128, and the ends of both power lines 132 are insulated and fixed to the side surface (right front side in FIG. 13) of the box 130. Each is electrically connected to the electrode 133.

Next, the operation of the human waste processing apparatus 15 housed in the temporary toilet 11 of the first embodiment will be specifically described.

<Use of Temporary Toilet 11 by User>

A user who intends to excrete urine and feces using the temporary toilet 11 opens the door 14 to enter the house 13 and excretes urine and feces to the toilet bowl 16. The excreted urine and urine fall from the discharge port (not shown) opened in the lower part of the toilet bowl 16 into the human waste treatment device 15 and are heated in the human waste treatment device 15, and the water, which is the major component, is evaporated and dried. Is processed.

<Insertion of urine and stool into the drying pot 51>

Then, as shown in FIG. 2, the large and small stools excreted toward the toilet bowl 16 pass through the lower outlet of the toilet bowl 16 and are guided further downward by the bellows-like joint 39. Then, it passes through an on-off valve (not shown) in the middle and flows down to the connection ring 55 to which the lower end of the joint 39 is connected. As shown in FIG.
Since the input port 56 is opened in the center of 5, the falling urine and urine is input into the internal space of the introduction part 54 through the input port 56. Since the bottom surface of the introduction portion 54 is inclined toward the direction of the drying pot 51, the urine and urine flow according to the inclined direction and flow into the internal space of the drying pot 51. It should be noted that part of the urine and urine is joint 39 and the introduction part 54.
After the user defecates, a small amount of washing water is sprayed from a tank (not shown) to the toilet bowl 16, and the attached large and small stools are washed together with the washing water into the drying pot 5.
1 can flow into the internal space.

<Heating of the drying pot 51>

After the urine and feces have been put into the drying cauldron 51, the drying cauldron 51 is then heated to start the process of evaporating and drying the stool and urine. In this heating, high-frequency power is supplied to the high-frequency coil 128 from a high-frequency power generator (not shown), the electromagnetic waves are agitated from the high-frequency coil 128, and the drying pot 51 and the heat storage body 60 are heated by the principle of electromagnetic induction heating. To do. First, the power supplied from the high frequency power generator is transmitted to the high frequency coil 128 via the electrode 133 and the power line 132. With the high frequency power supplied to the high frequency coil 128, the high frequency coil 1
Electromagnetic waves are generated in the vertical direction at 28. This high-frequency electromagnetic wave leaks out of the coil container 129, and the high-frequency electromagnetic wave passes through the bottom of the drying oven 51 approaching the upper surface of the coil container 129 and is mixed.

Therefore, electromagnetic waves of high frequency are agitated at the bottom portion of the drying pot 51 to cause a phenomenon of electromagnetic induction heating (the drying pot 51 is made of a metal material such as iron). The drying pot 51 itself generates heat. At the same time, this electromagnetic wave also mixes with the heat storage body 60 stored in the drying pot 51, and the heat storage body 60 itself also generates heat. Due to this electromagnetic induction heating, the drying cauldron 51 and the heat storage body 60 generate heat.
Is heated by being heated, and its temperature rises. When the temperature of the urine and stools gradually rises, the stored stool and urine is finally heated to a boiling temperature, and the water, which is a major component of the stool and urine, becomes vapor and evaporates from its surface.

<Supply and exhaust of air from the outside>

In this way, the stool and urine boil inside the drying cauldron 51, and most of the components of the water evaporate, but the fresh air supplied from the blower 36 by the blower path (not shown). Is injected into the drying pot 51 through the air supply hole 63. Oxygen contained in the external air supplied to the drying pot 51 comes into contact with boiling stool and oxidizes its components. At the same time, the water vapor and air evaporated in the drying pot 51 must be released to the outside.
For this reason, the steam and the air evaporated from the exhaust hole 64 are caused to flow out of the drying pot 51. And the exhaust hole 6
The water vapor and air flowing out of 4 pass through a reheating box and a catalyst box by a flow path (not shown), and the components causing the malodor are redox-oxidized, changed to an odorless state, and released to the outside. As described above, the processing after evaporating urine and urine is a conventionally known configuration.

When the drying pot 51 is heated,
The steam generated from the drying cauldron 51 tries to jet from the joint 39 through the lower opening of the toilet bowl 16 through the charging port 56, but an opening / closing valve (not shown) is provided in the middle of the joint 39. During the process of evaporation / drying, the open / close valve is closed, so that no foul odor or water vapor is ejected from the lower opening of the toilet bowl 16 into the house 13.

<Rotating Motion of Stirring Unit 28>

Simultaneously with the heating operation of the drying pot 51 by the high-frequency coil 128 described above, the motor 11 of the stirring section 28 is heated.
Power is supplied to 8 to start the stirring operation. When power is supplied to the motor 118, the rotation output of the motor 118 is decelerated in rotation speed via the gear box 119, and the output shaft 120 at the upper end is rotated at a low speed. Then, the pulley 123 fixed to the output shaft 120 also rotates at the same time, and as shown in FIGS. 5, 7, and 8, the belt 12
4, the pulley 95 is driven, and the rotation of the pulley 95 causes the drive shaft 76 fixed to the center thereof to rotate in the horizontal direction (the space between the pulley 95 and the drive shaft 76 is shown in FIGS. Since the key 97 is engaged with and intervenes as shown by, the rotation in the horizontal direction does not slip, and the pulley 95 and the drive shaft 76 rotate in synchronization.
As shown in FIGS. 10 and 11, the drive shaft 76 has its upper and lower portions held by bearings 84 and 91 fixed to the outer barrel 71, respectively, so that the drive shaft 76 rotates smoothly in the horizontal direction. That has been maintained. As described above, when the pulley 95 is driven via the belt 124, the rotational force is transmitted to the drive shaft 76 via the key 97, and the pulley 95 and the drive shaft 76 rotate simultaneously in the same direction.

In the lower part of the drive shaft 76, as shown in FIGS.
Since the stirring section 28 is suspended as shown in FIG. 9, the entire stirring section 28 rotates horizontally in the internal space of the drying oven 51 together with the drive shaft 76. In this rotation operation, the connecting plate 105 is connected to the connecting plate 78 fixed to the lower end of the drive shaft 76, and the connecting plate 105 includes a hanging pipe 107, an oblique pipe 108, and a suction pipe 109. Since the crank body 102 is suspended, the crank body 102 rotates in synchronization with the drive shaft 76 inside the drying pot 51. In this rotation operation, the suction pipe 109 rotates about the drive shaft 76 as a center of rotation while drawing a circular locus in the drying pot 51. In the rotational movement of the suction pipe 109, the opening at the lower end of the suction pipe 109 is kept at such an interval that it does not contact the bottom of the drying pot 51, and the suction pipe 109 is connected to the drying pot 5.
1 can rotate without contacting the bottom surface.

When the suction pipe 109 rotates, the triangular plates 110 and 11 fixed to the side surface of the suction pipe 109.
1 and the agitating plate 114 and the skirt plate 115 simultaneously perform a circular rotation in the drying pot 51. The rotation of the stirring plate 114 and the skirt plate 115 causes the stirring plate 114 to rotate.
Are slightly spaced apart from the inner wall of the drying pot 51, the lower end of the skirt plate 115 is slightly spaced from the bottom of the drying pot 51, and the stirring plate 114 and the skirt plate 115 are Rotate without contact. And the stirring plate 11
4, the skirt plate 115, as shown in FIG.
14. The space inside the drying pot 51 is divided into two by the skirt plate 115, and while maintaining this state, the stirring plate 114,
Since the skirt plate 115 rotates, the stirring plate 114 and the skirt plate 115 stir the large and small stools stored in the drying pot 51, and simultaneously push the heat storage body 60 stored in the drying pot 51. Will be rolled.

<Agitation of large and small stools by the heat storage body 60>

When the motor 118 operates in this way,
By the rotation output, the entire stirring unit 28 is rotated,
The heat storage body 60 charged into the drying pot 51 is rolled inside the drying pot 51 by the stirring plate 114 and the skirt plate 115. The stir plate 114 and the skirt plate 115 stir the large and small stools stored in the drying pot 51, and at the same time, the heat storage body 60 is rolled. The body 60 is agitated and agitated so that the temperature of the entire stool and urine rises uniformly. Moreover, when the heat storage element 60 is rolled, urine and urine are attached to the surface of each heat storage element 60, and the heat generated by the heat storage element 60 is transmitted to the urine and urine, increasing the temperature of the urine and urine. Performs auxiliary functions. In this way, while the urine and urine are being stirred by the heat storage body 60, the heat-generating temperature thereof is transmitted, and the temperature of the entire urine and urine is raised.

<End of evaporation / drying processing of stool by the drying pot 51>

As described above, by rotating the stirring section 28 while heating the drying pot 51 and the heat storage body 60 by the high frequency coil 128, the large and small stools stored in the drying pot 51 continue to boil, and most of the large and small stools are kept. The water, which is a component of, continues to evaporate. If this evaporating operation is continued, eventually all of the urine and urine stored in the drying pot 51 will be evaporated. When all of the large and small stools in the drying cauldron 51 are evaporated, it is not necessary to heat the drying cauldron 51 and the heat storage body 60 by the high frequency coil 128, and the evaporation / drying process must be completed. The end of this operation can be automatically performed by detecting a rise in the temperature of the drying pot 51 by a temperature sensor (not shown). That is, the temperature change on the side surface of the drying pot 51 is constantly monitored by a temperature sensor (not shown), and when urine and stools are present in the drying pot 51, the temperature of the drying pot 51 is maintained near the boiling point. ,
The temperature does not rise. However, when all the urine and stools are evaporated, the surface temperature of the drying cauldron 51 will rapidly rise,
By detecting this temperature change with the temperature sensor, it is possible to determine that all the large and small stools in the drying pot 51 have been evaporated. When it is determined by the temperature sensor that the evaporation of stools in the drying pot 51 has been completed, the power supplied from the high frequency power generator to the high frequency coil 128 is stopped, and the drying pot 5 by the high frequency coil 128 is stopped.
1. Heating of the heat storage body 60 is stopped.

<Cleaning process of the drying pot 51>

When all the large and small stools stored in the drying cauldron 51 are evaporated and dried in this way, most of the components of the water evaporate, but the organic and inorganic substances contained in the large and small stools become dust. And remains in the drying pot 51. When such dust adheres and accumulates on the inner wall and the bottom of the drying pot 51, the stirring plate 114, the skirt plate 115, and the heat storage unit 60 cannot rotate in the drying pot 51 due to long-term use. Will not be able to perform the processing function. For this reason, when the process of evaporating and drying the urine and urine has been completed, the process of cleaning the inside of the drying pot 51 must be performed next to remove dust remaining in the drying pot 51.

In this cleaning process, the motor 11
By rotating the agitating section 28 with the use of the air 8, air can be sucked from the upper end opening of the ventilation hole 77 provided in the drive shaft 76. That is, suction is started by a suction device connected to the valve 38 (the suction side of the blower 36 is connected by a communication pipe), and when the valve 38 is opened, the air in the ventilation hole 77 is discharged through the exhaust pipe 37. It will be aspirated. Then, a suspension pipe 107 constituting the crank body 102 connected to the lower end of the drive shaft 76,
Since the inclined pipe 108 and the suction pipe 109 communicate with the ventilation hole 77, air is sequentially sucked from the lower end opening of the suction pipe 109. When the air is sucked from the lower end opening of the suction pipe 109, dusts such as non-evaporable organic and inorganic substances remaining near the bottom of the drying pot 51 are sucked together with the air from the lower end opening of the suction pipe 109. Then, the dust sucked together with the air flows into the suction pipe 109,
Oblique pipe 108, hanging pipe 107 and ventilation hole 7
7 and is discharged from the drying pot 51 to the outside. The dust sucked together with the air is discharged to the exhaust pipe 37, the valve 3
8, the dust is captured by a dust separator (not shown) (having the same structure as a garbage bag in a vacuum cleaner), and the air is separated and cleaned to be discharged to the outside.

Even during this cleaning process, the motor 118 continues to operate, and the stirring unit 28 as a whole moves like a miso-rubbing motion in the drying pot 51 via the pulley 123, the belt 124, and the pulley 95. It rotates in a circular path. For this reason, the lower end opening of the suction pipe 109 rotates in a circular shape near the bottom of the drying pot 51, so that dust accumulated on the bottom of the drying pot 51 can be sucked up evenly.
When the stirring unit 28 rotates, the stirring plate 114 and the skirt plate 115 also rotate at the same time, and the heat storage body 60 rolls on the bottom of the drying pot 51. Therefore, the dust accumulated on the bottom of the drying pot 51 is stripped by the heat storage unit 60. In addition to having an action of removing dust, the dust accumulated in the bottom of the drying pot 51 is separated, and at the same time, dust is finely crushed so as to be easily sucked together with air.

<Stopping the cleaning process>

By sucking the dust accumulated in the drying pot 51 in this way, the cleaning process of the drying pot 51 can be performed, and if this process is continued for a predetermined time, the cleaning process is Complete. When the cleaning process is stopped, the motor 118 stops its operation, the stirring unit 28 stops without rotating, the valve 38 is closed, and the blower 3
6 will stop. Then, when the cleaning process is completed, each mechanism constituting the human waste processing apparatus 15 maintains its state and waits, and waits for a user who wants to use the temporary toilet 11 next and excrete the toilet 16. I do. By repeating such a series of cycles sequentially, the temporary toilet 1
The large and small stools excreted in the toilet bowl 16 can be dried odorlessly.

The shape seen from above is similar to the shape of a western kite floating in the air,
The corrugated side has a shape that is carved into a left-right symmetrical arc. When fixing the fixing plates 141 and 142 to the suction pipe 109, the acute-angled apex where the straight lines of the fixing plates 141 and 142 intersect each other is arranged toward the inner wall of the drying pot 51, and is formed in a corrugated shape. Is arranged so that the center of the side is directed toward the central axis of the drying pot 51 (the arrangement of the fixing plates 141 and 142 can be understood in FIG. 14). A rectangular side plate 143 is fixed between the straight sides (on the right front side in FIG. 15) of the fixing plates 141 and 142 (note that the other side plates are hidden in FIG. 15). However, other side plates having the same shape as the side plate 143 are fixed to the other straight sides of the fixing plates 141 and 142 by electric welding or the like). Then, the back surfaces of the stirring plate 144 and the stirring plate 145 which are bent in an arc shape are in close contact with the corrugated sides of the above-mentioned fixing plates 141 and 142, respectively. The sides and the stirring plates 144 and 145 are fixed to each other by electric welding or the like. The stirring plates 144, 145 are fixed to the side surfaces of the side plate 143 by electric welding, and the fixing plates 141, 142,
The side plate 143 and the stirring plates 144 and 145 form a structure hermetically sealed from the outside.

On the lower side of the stirring plate 144 bent in an arc shape, the upper side of the skirt plate 146 which is tapered forwardly is fixed by electric welding or the like, and the arc of the stirring plate 145 is formed. The upper side of the skirt plate 147, which is inclined in a taper shape toward the front, is fixed to the lower side bent into a shape by electric welding or the like. Due to this configuration, the stirring plate 1
44 and 145 and the skirt plates 146 and 147 form two corrugated curved surfaces symmetrically as if the seagull had spread its wings. The stirring unit 28 is a drying pot 51.
These stirring plates 14 are suspended in the inside.

The size is set such that a small gap is provided so as not to contact the inner wall of 1. Also, the skirt plate 14
The heights of the lower ends of 6, 147 are also set so as to be positioned at a slight interval so that they do not come into contact with the bottom surface of the drying pot 51 when the stirring unit 28 is suspended in the drying pot 51. There is.

<Operation of Second Embodiment>

When the agitating section 28 having such a shape is suspended on the bearing section 24 and the agitating section 28 is housed in the drying pot 51 and the motor 118 is driven, the bearing section 24 and the agitating section 28 are driven. Rotates. The stirring section 28 is rotated in the drying pot 51 about the central axis of the hanging pipe 107 as a center of rotation, and the suction pipe 109 separated from the central axis of the hanging pipe 107 by a miso rubbing motion in the drying pot 51. It will rotate like a circle. At this time,
The stirring plates 144 and 145 and the skirt plates 146 and 147 are interlocked with the suction pipe 109 to rotate in a circular shape in the inner space of the drying pot 51. By the rotation of the stirring plates 144, 145 and the skirt plates 146, 147, the heat storage body 60 stored in the drying pot 51 is pushed and rolled by these, and the action of stirring the large and small stools stored in the drying pot 51. I do. When the heat storage body 60 rolls, the stirring plates 144 and 145 and the skirt plates 146 and 147 are used.
Is formed in the shape of an arc having two curved surfaces such that the blades are widened to the left and right, so that the heat storage body 60 comes into contact with the two curved surfaces and rolls.

The stirring plates 144 and 145 and the skirt plate 1

The planar shape of both meniscal plates 151 and 152 is a crescent shape in which the front and rear sides are arcs, and a peripheral surface is formed by a curved surface C having a small radius of curvature and a curved surface D having a large radius of curvature. Therefore, the curved surface C projects in an arc shape and the curved surface D is recessed in an arc shape, as shown in FIG. The radius of curvature of the curved surface C is set to be substantially equal to the radius of curvature of the inner wall of the drying pot 51.
A fixing hole 153 having the outer diameter of the suction pipe 109 as its inner diameter is opened at the center of the meniscus 151.
A fixing hole 154 having an outer diameter of the suction pipe 109 as its inner diameter is opened at the center of 52. These fixing holes 15
3, 154 are inserted into the suction pipe 109, respectively, and are fixed to the suction pipe 109 by electric welding or the like at intervals so that both fixing holes 153, 154 are parallel to each other.

A back plate 155 obtained by bending a flat plate into an arc shape is brought into contact with each curved surface C of the meniscus 151 and 152, and the upper side of the back plate 155 is electrically welded to the curved surface C of the meniscus 151. The lower side of the back plate 155 is fixed to the curved surface C of the meniscus 152 by electric welding or the like. Further, the curved surface D of each of the meniscus plates 151 and 152 is in contact with a stirring plate 156, which is a single plate bent in an arc shape, and the upper side of the stirring plate 156 is electrically welded to the curved surface D of the meniscus plate 151. Etc., and the lower side of the stirring plate 156 is fixed to the curved surface D of the meniscus plate 152 by electric welding or the like. Further, the upper side of the skirt plate 157 inclined toward the front side is fixedly attached to the lower side of the stirring plate 156 which has an arc shape.

The meniscus 151 thus combined,
152, the back plate 155, and the stirring plate 156 form a three-dimensional structure in which a part of a cylinder is cut out in half a moon. In the relationship between the assembled structure and the suction pipe 109, the center of the rotation axis of the suspension pipe 107 and the meniscus 1
The centers of curvature of the curved surfaces C of 51 and 152 are set to be at the same position. Therefore, when the stirring section 28 is inserted into the internal space of the drying pot 51, the central axis of the hanging pipe 107 coincides with the center of the drying pot 51 as shown in FIG.
The curved surface C of the meniscus plates 151 and 152 is located at a distance B of several millimeters from the inner wall of the drying pot 51. When the stirring unit 28 is arranged in the drying pot 51 in this manner, the meniscus 1
The three-dimensional structure including 51, the meniscus plate 152, the back plate 155, and the stirring plate 156 is stored as it is in the internal space of the drying cauldron 51 and occupies a part of the internal space of the drying cauldron 51. As a result, as shown in FIG. 16, the space remaining in the drying cauldron 51 is the front surface of the stirring plate 156 and the drying cauldron 5.
Only the ball-shaped space of the abacus formed by the inner wall of No. 1 is left, and the other spaces are the meniscus plates 151, 1.

Simultaneously with the rotation of the suction pipe 109, the structure composed of the meniscus 151, 152, the back plate 155, the stirring plate 156, and the skirt plate 157 also rotates in the internal space of the drying pot 51 in synchronization. The heat storage body 60 is pushed by the rotation of the stirring plate 156 and the skirt plate 157, and the drying pot 51
It rolls at the bottom of the tray and stirs the large and small stools stored inside the drying pot 51.

In the stirring of urine and urine by the stirring section 28, unlike the first and second embodiments, about half the volume of the internal space of the drying pot 51 is blocked by this structure. Therefore, the large and small stools are agitated in the ball-shaped space of the abacus remaining in the drying pot 51. Therefore, the large and small stools thrown into the drying cauldron 51 will be stored in the heat storage body 60.
Since it is agitated only in a specific space in which is stored and does not move to another space, heat can be efficiently transferred and agitated reliably. Further, since only a small gap B is left between the outer periphery of the back plate 155 which is the back face of this structure and the inner wall of the drying pot 51, the back plate 15
When 5 rotates, wastes of urine and urine adhering to the inner wall of the drying pot 51 will be scraped off by the back plate 155, and no residue will adhere to the inner wall of the drying pot 51. Therefore, dust does not adhere to the inner wall of the drying pot 51 even after the stools have been dried, and it can be kept clean.

As described above, according to the invention of claim 1 of the present application, the container for accommodating the human waste contains the agitation means, and by rotating the agitation means, the urine is large and small. The human waste and the heat storage body can be rotated and stirred. The stirring means is composed of a crank body whose upper and lower end axes are displaced, and a pair of stirring plates bent in an arc shape. The stirring plate has blades spread below the crank body. It is arranged on the left and right. Since the upper end of the crank body is rotatably supported in the center of the upper part of the container, the lower end is located close to the inner wall of the container, which is located outside the central axis. Therefore, when the crank body rotates, the lower end of the crank body approaches the bottom of the container and draws a circular locus to make a rotary motion. At the bottom of the crank body, a pair of agitating plates are placed on the left and right side and fixed, so that both agitating plates make a rotational movement in the container as the crank body rotates, and their arc-shaped front faces are curved. It is possible to surely stir by pressing the human waste and the heat storage body in the container.

In addition, the axis of the upper end and the axis of the lower end of this crank body are horizontally offset, and the upper end of the crank body is pivotally supported at the center of the upper part of the container. The bottom of the body will rotate the bottom of the container in a circle. The crank body is formed in a pipe shape over its entire length, and air can flow between the opening at the lower end and the opening at the upper end. Therefore, when air is sucked through the opening at the lower end of the crank body, the air flows to the opening at the upper end of the crank body. Then, since the crank body rotates in a circular shape near the bottom of the container, the dust remaining on the bottom of the container can be sucked together with the air and flow outside from the upper end opening of the crank body. In this cleaning by suctioning dust, the crank body swirls in a circular shape at the bottom of the container, so that dust remaining in a wide range can be cleaned.

As described above, the crank body is shaped like a bent crank and rotated in a circular locus in the inner space of the container, whereby the human waste and the heat storage body in the container can be stirred. it can. At the same time, air and dust can be sucked from the lower end opening of the crank body, and the cleaning process can be performed after the heating / evaporating process of the human waste is completed. Therefore, the crank body can efficiently perform the two functions of stirring and cleaning, and the cleaning efficiency is higher than that of the structure in which the rotary shaft is pivotally supported in the center of the container.

Further, since the container can be fixed, the container itself can be firmly held, as compared with the conventional human waste treating apparatus in which the container storing the human waste is rotated to stir the human waste. 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, the upper end of the crank body is pivotally supported at the center of the upper part of the container, and a pair of arc-shaped stirring plates are arranged on the left and right, and fixed to the lower part of the crank body as if the blades were widened. .

Therefore, the space at the bottom of the container can be divided into two parts by both stirring plates, and the heat storage body can be arranged in the partitioned space, so that the human waste can be surely stirred. Also, two curved surfaces are formed as if the blades were spread by a pair of stirring plates, and since the joining line of both stirring plates is located in the center of the container, it is possible to push the heat storage body around each curved surface. Therefore, the heat storage body can be rolled in a circular shape at the bottom of the container without moving to the center of the container.

It's stuck. The radius of curvature of the back surface of the crank body is set to substantially match the radius of curvature of the inner wall of the container. Therefore, the stirrer contained in the container is rotatably held close to the inner wall of the container. Therefore, the portion of the container into which the excrement and the heat storage body are put becomes an independent space, and the heat for heating the excrement is transmitted to the narrow space, so that the temperature of the excrement can be rapidly raised. Further, since a narrow gap is provided between the container and the agitator, it is possible to prevent dust remaining after evaporation of human waste from adhering to the inner wall of the container.

According to the invention of claim 3 of the present application, the center of the bottom of the container is projected upward and the periphery thereof is formed into a gentle slope, and the heat storage body is circular around the slope. It will roll while drawing a trajectory. For this reason,
The multiple heat storage bodies will always move to the lowest position on the slope, and even if the heat storage bodies are pushed around by the stirring plate, they do not move to the center of the bottom of the container, but roll around the bottom of the container in a circle. To be made. For this reason, the excrement of the human waste is surely carried out, and further, during the cleaning process, since it rolls over a wide range of the container, the separation and pulverization of the dust are efficiently carried out.

According to the invention of claim 4 of the present application, the container is
It is composed of a flat plate-shaped holding plate and a cylindrical drying pot having an open top, and a closed container can be formed by bringing the upper opening of the drying pot into close contact with the holding plate. Therefore, the structure of the container can be simplified, and the assembly,
This will facilitate the disassembly work.

According to the invention of claim 5 of the present application, the lower ends of the pair of stirring plates fixed to the crank body are bent at the upper ends thereof in accordance with the curved surfaces of the respective stirring plates, and the lower ends thereof are respectively arranged. Skirt plates inclined toward the front of the stirring plate are fixed to each other. For this reason, each skirt plate has a surface inclined toward the front side at the lower part of each stirring plate, and the inclined surface can be scraped up and stirred, so that the stirring of human waste is performed efficiently. It will be.

According to the invention of claim 6 of the present application, a skirt plate whose plane is inclined toward the curved direction is provided on the curved surface of the crescent-shaped lower end of the front surface of the stirring body fixed to the crank body. It's stuck. For this reason, the skirt plate has a surface that is inclined toward the front side in the lower part of the agitator, and since the human sewage can be scraped up and agitated by this inclined surface, the agitation of the human waste is performed efficiently. Become.

According to the invention of claim 7 of the present application, the drive shaft is pivotally supported by the container, and the upper end of the crank body is connected to the lower end of the drive shaft. Therefore, since the drive shaft is rotatably held with respect to the container, the rotation of the crank body can be secured by the drive shaft. A vent hole is formed vertically through the center of the drive shaft, and the vent hole communicates with the pipe-shaped upper end opening of the crank body. For this reason,
The ventilation holes can communicate with each other inside and outside the container, and can perform the functions of rotation and air circulation.

According to the invention of claim 8 of the present application, since the container is heated by the electromagnetic heating means for generating a high-frequency electromagnetic wave, it is possible to prevent the occurrence of a fire without using heat power or the like. it can. Further, since the container is heated by electromagnetic heating, the thermal efficiency is improved and the container is efficiently heated, so that wasteful consumption of energy can be reduced.
