EXAMPLES Examples of the portable toilet of the present invention will be described below.

FIG. 1 is a perspective view showing the entire portable toilet of one embodiment of the present invention, FIG. 2 is a sectional view showing the structure of the portable toilet of one embodiment of the present invention, and FIG. 3 is one embodiment of the present invention. FIG. 3 is a cross-sectional view of the main parts showing the structure of the lid part of the portable toilet of FIG.

In FIG. 1, the lid portion 2 has an upper opening 2a on which the buttocks are placed, and the base portion 3 serves as a whole base and has an armrest portion 3a. A main body 1 forming substantially the whole of the portable toilet of the present embodiment is composed of a lid portion 2 having an upper opening 2a and a base portion 3 having an armrest portion 3a which serves as a base of the whole. However, when implementing the present invention, the main body 1
The lid 2 and the base 3 can be integrated together.

As shown in FIG. 3, the upper opening 2a of the lid 2 is shown.
Is formed in a size that allows urination and defecation with the buttocks resting. In addition, the weight of the human body is dispersed around it and is added to the base 3. The lower surface 2b around the lid portion 2 has a concave shape so that odors are trapped on the lower surface 2b side of the lid portion 2.

An armrest portion 3a is formed integrally with the base portion 3 of the main body 1. This armrest 3a can be used as a support for the body and also as a guide for the buttocks. Further, it also has a function of guiding the lid portion 2 so that the lid portion 2 can be placed at a fixed position on the upper surface of the base portion 3. That is, when the lid portion 2 is placed on the upper surface of the base portion 3, the positions of both sides and the rear portion are determined according to the armrest portion 3 a, and the lid portion 2 is moved to the upper surface of the base portion 3 to move the lid portion 2 to the upper surface of the base portion 3. Can be placed in place.

As shown in FIG. 2, the processing container 4 which can be inserted into and removed from the front opening portion 3b of the base portion 3 of the main body 1 includes a lid portion 2
Has an opening wider than the upper opening 2a. The processing container 4 is basically a substantially rectangular parallelepiped box-shaped container having an upper opening, and has a handle portion 41 on the front surface thereof, which can be inserted / removed and carried. At the center of the processing container 4, an agitating means 42, which is supported by bearings on both sides, is provided. The stirring means 42 is a shaft 42a protruding rearward of the processing container 4.
The rotational force is obtained from the gear 43 attached to the. The stirring means 42 has a plurality of stirring elements 42b, and the stirring element 42b rotates in the processing container 4 by the rotation of the shaft 42a. The stirring element 42b of the present embodiment has a bottomed cylindrical body parallel to the shaft 42a and is connected to the shaft 42a side by a rod.
It is connected in a balanced arrangement with respect to rotation of 60 degrees. Also, with respect to the rotation of the shaft 42a,
It is arranged so that the load is even. Therefore,
In the processing container 4, the shaft 42a is rotated by the rotational force applied to the gear 43, and the plurality of stirring elements 42b are rotated. This rotation has a small contact resistance due to the bearing, and can be easily rotated.

The rear portion of the processing container 4 is lower than the front surface having the handle portion 41, and is a part of an exhaust path described later. Further, the main body 1 of the present embodiment is separated into the lid portion 2 and the base portion 3, but the main body 1 in which the both are integrated may be a processing container 4 which can be inserted and removed freely.

A thin metal plate 31 is laid under the front opening 3b of the base 3 into which the processing container 4 is inserted and removed. Although the upper surface of the metal thin plate 31 is substantially smooth, a heater 32 including a thermistor is arranged on the lower surface thereof. A heat insulating material 33 made of a foamable synthetic resin is filled between the lower surface of the metal thin plate 31 and the bottom surface of the base 3. Therefore, the amount of heat generated by the heater 32 is efficiently transferred to the processing container 4 side. The heater 32 is mounted in the main body 1 and constitutes a heating means for controlling the temperature of the processing container 4 mounted in the main body 1 within a predetermined temperature range. Since the heater 32 in the present embodiment is composed of a thermistor, the temperature control is performed by the heater itself. However, the on / off control of the energizing current may be performed by temperature detection. The value may be controlled.

A controller 34 is arranged on the opposite side of the front opening 3b of the base 3 into which the processing container 4 is inserted and removed. The controller 34 electrically controls the entire portable toilet of this embodiment.

The electric motor 35, which is controlled to rotate at a constant speed by the controller 34, applies a rotational force to the gear 43 of the processing container 4 by the output gear 36 after the predetermined deceleration. That is, when the processing container 4 is mounted on the main body 1, the mounting causes mechanical coupling between the output gear 36 and the gear 43 to impart a rotational force to the stirring means 42.

Similarly, the exhaust fan 37 whose rotation is controlled by the controller 34 exhausts the air in the processing container 4 through the catalyst deodorizer 38 and the exhaust port 39 of the base 3.
That is, the exhaust fan 37 forcibly exhausts the air in the main body 1 from the exhaust port 39 of the base 3 through the catalyst deodorizer 38.

Next, the operation of the portable toilet of this embodiment constructed as above will be described.

First, the crushed rice husks, wood chips, etc. and aerobic high-temperature fermenting bacteria are mixed and put in the processing container 4 to a height of 50 to 60%. In the present embodiment, a mixture of crushed rice husks, wood chips, etc. and aerobic fermentative bacteria was added, but when the present invention is carried out, fine powder of plant constituents and aerobic fermentative bacteria may be used. The aerobic fermentative bacterium used in this example was an aerobic thermophilic fermentative bacterium. However, when carrying out the present invention, it is not limited to aerobic high-temperature fermenting bacteria, and any aerobic fermenting bacteria may be used.

Since the temperature at which the aerobic high-temperature fermenting bacterium used in this embodiment can operate satisfactorily is in the range of 45 to 65 ° C., the temperature inside the processing container 4 is controlled by the heater 32 as a heating means. Within the range of 50 to 60 ° C., the agitated means 4 constantly mixes and agitates the crushed rice husks, wood chips and the like in the processing container 4 with the aerobic fermenting bacteria under the adjusted temperature conditions.

Further, the exhaust fan 37 is always driven,
The air in the main body 1 is exhausted to the exhaust fan 3 through the catalytic deodorizer 38.
7 forcibly exhausts from the exhaust port 39 of the base portion 3. At this time, the catalytic deodorizer 38 removes the odor of the ammonia system, but during the decomposition treatment of the usual effluent by the aerobic fermenting bacteria,
No odor is generated due to the nature of the fermenting bacteria. Therefore, the catalytic deodorizer 38 particularly contributes to the removal of malodor during excretion. In addition, the exhaust fan 37 is always driven to supply oxygen to the aerobic fermentative bacteria during the decomposition process of the exhaust gas, and the temperature of the lid portion 2 in the temperature range 50 to 60 in the processing container 4.
This is for making the temperature less likely to be affected by the temperature of about 35 to 40 ° C. The exhaust fan 37 of this embodiment constitutes an air supply means for introducing outside air into the processing container 4 mounted on the main body 1.

In this state, when the person sits on the lid portion 2 of the main body 1 and excretes from the upper opening 2a of the lid portion 2, the excrement is stirred in the processing container 4 under the temperature range of 50 to 60 ° C.
In step 2, rice husks, wood chips, etc. and aerobic fermentative bacteria are mixed and stirred. Therefore, the excrement is instantly mixed and stirred by the stirring means 42 with the rice husks, wood chips, etc. and the aerobic fermenting bacterium, and the ammonia-based malodor is slightly generated, and is completely removed by the catalytic deodorizer 38.

When the excrement is mixed and stirred by the stirring means 42 with rice husks, wood chips, etc. and aerobic fermenting bacteria, the rice husks, wood chips, etc. are fermented and decomposed by microorganisms and aerobic fermentative bacteria by aerobic high-temperature fermenting bacteria which are active. As a result, crushed rice husks and wood chips in the processing container 4 increase. This increase due to excrement can be returned naturally by fertilizing rice husks, wood chips, etc. in the processing container 4 as fertilizer at a timing of once every 20 to 30 times of use.

Fermentative decomposition of excrement by aerobic fermenting bacteria during this period does not cause an unpleasant odor due to aerobicity, and kills Escherichia coli and other parasite eggs that are harmful to humans at high temperatures. Further, even if rice husks, wood chips, etc. in the processing container 4 are applied as fertilizer, no bad odor is generated and bacteria are not propagated due to the odor.

When the rice husks, wood chips, etc. in the processing container 4 are applied as fertilizers or discarded, the processing container 4 is used as the main body 1.
Withdraw from. At this time, the mechanical connection between the output gear 36 and the gear 43 is released by the mounting. When mounting the processing container 4 on the main body 1 again, the processing container 4 is fitted into the main body 1. By the insertion, the output gear 36 and the gear 43 are mechanically coupled.

As described above, the portable toilet of this embodiment has the main body 1 having the upper opening 2a on which the buttocks are placed, and the main body 1 can be freely inserted into and removed from the main body 1 by using fine powder of plant constituents such as rice husks and wood chips. When the processing container 4 for storing aerobic fermentative bacteria is mounted on the main body 1, the processing container 4 is mounted inside the main body 1, and the stirring means 42 for mechanically connecting the processing container 4 to obtain a rotational force. A drive unit including an electric motor 35 that outputs a rotational force to the stirring unit 42, and is mounted in the main body 1,
A heating means including a heater 32 for controlling the temperature of the processing container 4 attached to the main body 1 within a predetermined temperature range, and an air supply means including an exhaust fan 37 for introducing outside air into the processing container 4 attached to the main body 1. And a deodorizing unit including a catalytic deodorizer 38 that deodorizes the air discharged when the outside air is introduced by the air supply unit including the exhaust fan 37.

In the use of the portable toilet of this embodiment, first, the temperature of the processing container 4 mounted on the main body 1 is changed to the heater 32.
Is controlled within a predetermined temperature range by a heating means consisting of
The environment in the processing container 4 is set to a condition suitable for the activity of aerobic fermentative bacteria. The processing container 4 that is insertable into and removable from the main body 1 having the upper opening 2a on which the buttocks are placed, and stores the fine powder of the plant constituent and the aerobic fermentative bacteria, when the processing container 4 is attached to the main body 1, By the attachment, the driving means including the electric motor 35 and the output gear 36 and the gear 43 are mechanically coupled to rotate the stirring means 42, whereby the excrement and the fine powder of the plant constituents and the aerobic fermentative bacterium. Are stirred, and rice husks, wood chips, and the like are fermented and decomposed by the aerobic high-temperature fermenting bacteria in which the rice husks, wood chips, etc. are actively active, and apparently the amount of crushed rice husks, wood chips in the processing container 4 increases. To increase the amount of rice husks and wood chips due to this excrement, the excrement can be returned naturally by fertilizing the rice husks and wood chips in the processing container 4 as fertilizer.

Therefore, the excrement can be treated in the portable toilet and the odor is not emitted.

When the rice husks, wood chips, etc. in the processing container 4 are to be taken out, the processing container 4 is pulled out from the main body 1. At this time, the mechanical connection between the output gear 36 and the gear 43 is released by the mounting. When the processing container 4 is attached to the main body 1 again, the output gear 36 and the gear 43 are mechanically coupled by the insertion thereof. Therefore, the processing container 4 that is normally carried does not have an electrical part, so that it can be washed with water, and the carrying is light. Of course,
Since there are few mechanical parts, it is possible to avoid a situation where a failure occurs due to a shock or the like.

The processing container 4 mounted on the main body 1 is deodorized by the deodorizing means including the catalytic deodorizer 38.

Particularly, since the fine powder of the plant constituent and the aerobic fermentative bacterium of the present embodiment use the widely used materials,
It can be cheap.

By the way, the air supply means for introducing the outside air into the processing container 4 mounted on the main body 1 of the above-described embodiment is the exhaust fan 37 for exhausting, but in the case of implementing the present invention, It can be an intake fan that forcibly intakes air.

In the deodorizing means of the above embodiment, the processing container 4 mounted on the main body 1 comprises a catalyst deodorizer 38,
As the deodorizing means for carrying out the present invention, a known deodorizing means for deodorizing air can be used.

[0039]

As described above, in the portable toilet according to the present invention, the temperature of the processing container attached to the main body is controlled within a predetermined temperature range by the heating means, and the environment in the processing container is controlled by the aerobic fermenting bacteria. Under the conditions suitable for activities, the processing container that contains the fine powder of the plant constituent and the aerobic fermentative bacterium,
When the treatment container is attached to the main body, the attachment mechanically connects to the driving means to rotate the stirring means, whereby the excrement, the fine powder of the plant constituents and the aerobic fermenting bacteria are stirred. The effluent is fermented and decomposed by microorganisms and aerobic fermenting bacteria by aerobic thermophilic fermenting bacteria in which rice husks, wood chips, etc. are active. Apparently, the amount of rice husks and wood chips increases due to the excrement, and the excrement can be naturally returned by applying the rice husks, wood chips, etc. in the processing container as fertilizer.

Therefore, the excrement can be treated in the portable toilet and the odor is not emitted. In addition, the operating cost is low because the material is ordinary.
