BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a simplified toilet exhaust structure according to the present invention. FIG. 1 is a longitudinal sectional view showing a main part of a simple toilet having the present exhaust structure. 2 is a schematic sectional view taken along the line II-II of FIG. 1, and FIG. 3 is a longitudinal sectional view of a main part of a tank structure of a simple toilet having an exhaust structure. FIG. 4 is a partial perspective view of the stirring blade 2 used for the tank structure of the simple toilet having the exhaust structure.
This simple toilet is ideal for various construction sites, civil engineering sites, and places where water use is restricted. The step 17 is provided outside the entrance door 26, and the inside is stepped. The toilet 1 is fitted in the upper stage, and the lower end opening 1 a of the toilet 1 is adjacent to the opening 9 a of the upper lid 9 of the tank 3.

As shown in FIG. 2, the tank 3 has a circular outer periphery, a double bottom (FIG. 1), and an upper lid 9 fixed to the upper end. The bottom plate 3b is fixed to face the lowermost bottom plate 28 located at the lowermost side of the tank 3. And this bottom plate 3b and the bottom bottom plate
28, a bottom chamber 3c is formed. This bottom chamber 3c
It is preferable to set the height to about 1/5 to 1/20 of the height of the entire tank. In addition, the ratio can be appropriately designed and changed depending on the frequency of use of the portable toilet and the like. Next, the bottom plate 3b is formed in a slightly mountain-like manner from the periphery to the center. As an example, the gradient is about 1/50. The reason why the bottom plate 3b is formed to be slightly mountainous is that the air generated in the bottom chamber 3c is collected at the center and the internal pressure of the heat retaining liquid 6 stored in the bottom chamber 3c is used. This is for releasing the air from the extraction pipe 7 to the outside.

Further, due to the slight taper,
By moving the plant strips 4 stored in the storage chamber 3a above the center from the center to the periphery, and then moving them upward at the periphery by the stirring blade 2, the plant strips 4 are moved.
This is to ensure convection. The lower end of the cylinder 27 is fixed to the center of the lowermost bottom plate 28, and the cylinder 27 penetrates the bottom plate 3b in a liquid-tight manner. The cylinder 27 has an air supply pipe in the bottom chamber 3c.
One end of 22 is connected. This air supply pipe 22 is shown in FIG.
As described above, air is supplied to the cylinder 27 by a blower (not shown) through the outer periphery of the bottom chamber 3c, and air is blown into the storage chamber 3a from a plurality of air blowout holes 24 on the upper side thereof to remove microorganisms adhering to the plant chips 4. It is to increase the activity. The plurality of air outlets 24 are formed at positions higher than the surface of the bottom plate 3b. Even if urine is present on the bottom plate 3b to some extent, urine does not enter the cylinder 27 from the air outlets 24. Located at height.

A liquid heating heater 5 is inserted in the bottom chamber 3c. The base of the liquid heating heater 5 is fixed to the periphery of the bottom chamber 3c in a liquid-tight manner. Further, in order to maintain the temperature of the heat retaining liquid 6 in the bottom chamber 3c at a predetermined temperature (about 10 ° C. to 20 ° C., preferably about 15 ° C.) by the liquid heating heater 5, as shown in FIG. The heater 29 is attached to the periphery of the bottom chamber 3c, and the liquid heating heater 5 is ON-OFF controlled based on the output signal. Then
The lower end opening of the water surface inspection cylinder 8 communicates with the periphery of the bottom chamber 3c, and the upper end of the water surface inspection cylinder 8 is extended to the upper end position of the tank 3 and is open to the atmosphere. In addition, bottom room 3c
The air vent pipe 7 is housed, and its tip is opened to the upper end of the center of the bottom chamber 3c, and the other end is bent in an L-shape and housed in the water surface inspection cylinder 8. Then, water is supplied from the water surface inspection cylinder 8 into the bottom chamber 3c, and the inside of the bottom chamber 3c is filled with the liquid 6 for keeping heat. A drain plug 23 used for discharging the heat retaining liquid 6 is detachably fixed to the outer periphery of the bottom chamber 3c.

Next, a lower bearing 11 is provided on the inner surface of the upper end of the cylinder 27.
The lower end of the drive shaft 12 is fitted in a liquid-tight manner via the seal member 30 (FIG. 3). A flange is formed at the lower end of the drive shaft 12 and covers the upper end of the cylinder 27. A shaft portion at the center of the flange portion is supported by the lower bearing 11, and a seal member 30 is interposed between the shaft portion and the inner surface of the cylinder 27. The upper end of the drive shaft 12 penetrates the upper cover 9 (FIG. 1), is supported by an upper bearing 10 mounted on the upper cover 9, and has its drive shaft
The upper end of 12 is connected to the rotating shaft of a motor 15 with a speed reducer. Fixed to the drive shaft 12 is an edge of a vertical, relatively narrow plant strip retraction guide 14. The lower end of the plant strip retraction guide 14 is close to the cylinder 27, and a scraper portion 14a is formed there. This scraper part 14a
The rotation of the drive shaft 12 removes the plant debris 4 attached to the outer periphery of the cylinder 27, and opens the air blowing hole 24.

Next, the drive shaft 12 is provided with three agitating blades 2 radially protruding below the middle portion in this example, with the height thereof being changed. As shown in FIG. 4, the stirring blade 2 has a support bar 31 fixed to the lower surface of a steel plate bent into an obtuse angled cross section as shown in FIG. 4, and one end thereof is fitted into a through hole (not shown) of the drive shaft 12. The attachment part is fixed by welding. The upper edge of the stirring blade 2 is attached at a position about 5 ° to 7 ° below the horizontal plane. At the tip of the stirring blade 2, a plant strip guide 13 is fixed upright at an angle of about 45 ° with respect to the axis of the stirring blade 2. The stirring blade 2 rotates in the direction of the arrow in FIG.
The plant chip guide 13 returns the relatively large chips, which tend to be close to the periphery of the tank 3, to the center, and stirs the large chips and the small chips so as to be substantially uniform.

Next, the upper lid 9 is provided with a lower end opening 19a of a relatively large-diameter short tubular exhaust flow deceleration chamber 19 on the opposite side of the lower end opening 1a of the toilet bowl 1 with respect to the motor 15 with a speed reducer. Is provided. The lower end of the chamber 19 is cut at about 45 ° with respect to the axis, and the long axis is arranged in the radial direction of the upper lid 9. The lower end of an exhaust pipe 20 having a smaller diameter than the upper end of the chamber 19 is hermetically connected. The upper end of the exhaust pipe 20 is opened to the outside of the toilet main body 16, and the air staying at the upper end of the storage chamber 3 a of the tank 3 is discharged to the outside by the ventilation fan 25. At this time, air flows into the tank 3 from the upper end opening of the toilet 1.

The reason why the exhaust pipe 20 is provided in the upper lid 9 via the chamber 19 is that the exhaust opening in the tank is connected to the large-diameter exhaust flow deceleration chamber 19 so that the exhaust opening is formed. This is because the airflow in the part can be extremely slowed down. Thereby, the dust and the like used for the service due to the exhaust do not block the opening. That is, dust and the like crushed by the stirring blade 2 do not block the exhaust port and cause a failure. Since a small-diameter exhaust pipe 20 is connected to the upper end of the chamber 19,
A compact exhaust path can be formed, and an exhaust structure for a simple toilet with good appearance can be provided. Next, four or more rollers 21 are pivotally supported on the lower surface of the bottom bottom plate 28 so that the entire tank can be taken out of the toilet body 16. That is, in this example, one lower side of the toilet main body 16 is opened, and the tank 3 can be pulled out from there.
Inspection and maintenance in the tank 3, replacement of the plant pieces 4, and the like can be easily performed.

[0015]

[How to use] First, from the upper end of the water surface inspection cylinder 8 to the bottom chamber 3
Fill c with water. Then, chips made of cedar thinned wood or the like are inserted into the storage room 3a from the opening of the upper lid 9 so as to be about eight minutes into the storage room 3a. This tip
It is preferable to remove oil by boiling. The tip is
It is generally preferred that the material be flat and torn so as to form irregularities on the flat surface. The maximum length of the tip is 1
It is preferably about 3 cm to 3 cm and about 5 mm or less in thickness. Further, in addition to the chips, extremely small chips having a grain shape can be mixed. It is preferable that the motor 15 with the speed reducer and the heater 5 for liquid heating are automatically controlled via a control device (not shown). In this example, the liquid heating heater 5 is controlled to be ON or OFF based on the temperature detected by the temperature detector 29 provided at the peripheral portion of the bottom chamber 3c, and the temperature of the heat retaining liquid 6 in the bottom chamber 3c is 10 ° C. About 20 ° C, preferably 15 ° C
It is held back and forth.

The motor 15 with a speed reducer rotates the drive shaft 12 very slowly, and its rotation speed is preferably about one rotation every 20 seconds to 2 minutes. The motor 15 rotates at regular intervals, and detects a person using the toilet to rotate the drive shaft 12. Therefore, the motor 15 with the speed reducer is driven intermittently. The ventilation fan 25 is constantly driven.
The plant strips 4 of the storage room 3a are moved from the lower end of the toilet 1
The excrement and dirt paper that has fallen upward are drawn downward by the rotation of the drive shaft 12. Then, the night soil and chile paper absorb moisture immediately by the plant strips 4 and gradually move to the periphery by the stirring blade 2. Then, most of the microorganisms are decomposed into water and carbon dioxide by microorganisms attached to the plant chips 4 and microorganisms contained in the night soil. Similarly, Chilean paper is broken down into water and carbon dioxide. At this time, the inside of the storage chamber 3a is maintained at a high temperature of about 60 to 80 ° C., and E. coli and the like inside die. Then, the water vapor is released from the gap between the plant pieces 4 to the upper space where the water vapor has accumulated, and is discharged outside through the chamber 19 and the exhaust pipe 20. At this time, the odor in the tank 3 is also efficiently released to the outside.

Due to the presence of the deceleration chamber 19, the odor staying in the upper portion of the tank 3 can be reliably exhausted to the outside. At this time, since the air in the toilet main body 16 is sucked from above the toilet 1, the odor in the tank is not released into the toilet, and a clean simple toilet is obtained.

Further, a large-diameter exhaust flow deceleration chamber 19 is provided at the exhaust opening in the tank, and the air flow at the opening can be extremely slowed down. Dust paper or the like does not block the opening. That is, the dust paper pulverized by the stirring blade 2 does not block the exhaust port, and does not cause a failure. Since a small-diameter exhaust pipe 20 is connected to the upper end of the chamber 19, a compact exhaust path is formed, and a simple toilet exhaust structure with a good appearance can be provided. Furthermore, plant fragments 4
The gas component of human waste, which is decomposed into water vapor and carbon dioxide by microorganisms attached to the toilet, is quickly eliminated, and moisture does not drift in the toilet. At the same time, it is possible to prevent the powder of the plant chips 4 finely divided by the stirring blade 2 from drifting in the toilet.

According to the second aspect of the present invention, since the axis of the chamber 19 is directed outward in the radial direction of the tank 3 and obliquely upward with respect to the horizontal, the odor staying at the central portion in the tank 3 is reduced. The guide can be smoothly led to the exhaust pipe 20 arranged along the wall surface of the toilet body 16. According to the third aspect of the present invention, the lower end opening 1a of the toilet 1 and the chamber 19 are provided on both sides of the motor 15 for driving the stirring blades arranged at the center of the upper lid 9.
