Description

  The present invention relates to, for example, (a) a manure processing apparatus for extinguishing manure in indoor portable toilets used in homes, elderly care facilities, hospitals and the like as shown in FIG.

  As a self-processing indoor portable toilet (hereinafter referred to as a portable biotoilet) that extinguishes excreta by utilizing the decomposition action of microorganisms, (b) a toilet seat 3 having a chair function as shown in FIG. (Hereinafter referred to as a chair toilet seat 3) and a toilet tank 4-1 or 4-2 (hereinafter referred to as a manure processing apparatus) equipped with a manure elimination process function installed in the lower part thereof are known. Some are commercially available.

  On the other hand, the indoor portable toilet of (a) is composed of a chair toilet seat 1 having the same function as the chair toilet seat 3 of the portable biotoilet of (b) and a detachable toilet tank 2 as a mere waste reservoir. If a manure processing apparatus having the same function as the manure processing apparatus 4 of (b) is incorporated in (a) instead of the tank 2, (a) can be a portable biotoilet similar to (b).

  However, in the conventional manure processing apparatus 4-1 of (b), as shown in FIG. 2, it is the stirring form similar to a cultivator, and a container cross section is U-shaped. As will be described later (0008 and 0009), the feces and urine treatment apparatus having such a form is a feces and urine that falls from the chair toilet seat 1 into the portable toilet for indoor use (a) manufactured by various manufacturers having different shapes and sizes. However, it has not been easy to complete in a short time while overcoming the problem of secure containment. For this reason, the feces and urine treatment apparatus 4-1 of (b) is not a single product, but is integrated with a dedicated chair toilet seat 3 adapted to the shape, size and structure of the portable biotoilet of (b). It is incorporated as part of the product.

  On the other hand, the excrement disposal device 4-2 (Patent Documents 1 and 2) adopts a stirring form in a cylindrical container as in the present invention, but in the disclosed information, it always has a deodorizing mechanism. It has become. Now, in the decomposition and extinction of manure in the cylindrical container, including the method of the present invention, the stirring method of the wood chip and the receiving manure (hereinafter referred to as the filling material) as the microbial matrix is a rotating blade in the cylindrical container. Employs a method of stirring the filling material with a drive motor provided at the bottom of the container. These public information always includes a deodorization mechanism, apart from the relationship between complete disappearance of feces and urine and fecal odor. For this reason, since the apparatus mechanism is complicated and it is difficult to reduce the size of the entire apparatus, the manure processing apparatus 4-2 is commercially available in the same manner as the manure processing apparatus 4-1. It is not easy and versatile for incorporation in an indoor portable toilet.

  In addition to the above-described 4-1 and 4-2, as a feces and urine treatment apparatus that can be incorporated in an indoor portable toilet, the patent is disclosed in Patent Document 4 by rotating the feces and urine receiving container, There is a thing in which the filler is agitated by the vibration of Document 3. However, the case of Patent Document 4 can be classified into 4-1 stirring modes, and it is clear that the stirring force is inferior to that of 4-1. In addition, it is obvious that the vibration method of Patent Document 3 causes the user to feel uncomfortable if the device vibrates in the room. From such a viewpoint, the methods of Patent Documents 3 and 4 lack practicality.

For the above reasons, even if a person who wants to use a portable biotoilet owns a portable toilet for indoor use (a), he / she purchases a manure treatment device instead of a toilet bowl, There was no means to make a toilet, and there was no choice other than purchasing an expensive portable biotoilet product in which a chair toilet seat and an excrement disposal device were integrated as shown in (b).
JP2002-238803 (P2002-238803A) JP2002-355277A (P2002-355277A) JP2003-265355A (P2003-265355A) JP2003-180558A (P2003-180558A)

  In order to reliably store manure falling from the chair toilet seat 1 of the indoor portable toilet of (a), even if the manure processing apparatus is in the form of the manure processing apparatus 4-1 of (b), As shown in FIG. 3, the problem can be solved by connecting the main body opening 1a (hereinafter referred to as the main body opening 1a) of the chair toilet seat 1 of (a) and the receiving port 4b of the manure container 4a with a thin plate 4c.

  However, the shape and size of the main body opening 1a of (a) vary depending on the manufacturer or type, and further, the space depth and shape of the lower portion of the main body opening of the chair toilet seat 1 of (a) also vary. It is. Under such conditions, the excretion of the applicant and the next excretion are limited in the place of residence of the applicant who is physically restricted who must use the portable toilet (a) regularly. Within a limited time (usually 2 to 3 hours), a thin plate 4c, which is expected to have a complicated shape, can be quickly produced on the spot by the method described in 0008 of a conventional manure processing apparatus as shown in (b). (A) It is actually difficult to assemble the toilet.

  The present invention has been made in view of such a problem, and at the same time, responds to the desire of a person who wants to easily convert a portable toilet for their own use into a biotoilet. It aims at obtaining the manure processing apparatus which can be easily constructed in a short time. Another object of the present invention is to provide a manure processing apparatus that suppresses the disappearance of manure and the generation of fecal odor. The present invention can be applied to organic substances other than manure.

The present invention realizes ease of mounting and versatility as a device that is installed in the interior of a portable toilet for indoor use instead of a toilet tank (soil storage container) in order to eliminate feces and urine by utilizing the decomposition action of microorganisms. Therefore, as shown in FIG. 4, a cylindrical manure container 5a having a height adjusting mechanism is provided, and the side surface of the manure container 5a has a side surface of the manure container 5a to suppress idling of the filler and improve stirring efficiency. It has a stirring mechanism provided with the protrusion 5e.
Furthermore, as shown in FIG. 4, a scraper that moves while being in close contact with the side surface of the container in order to suppress the formation of a stool film that accumulates over time on the side surface of the stool container 5a, which is one of the sources of stool odor. 5f is provided in the stirring blade 5c that is rotated by a motor driving the stirring mechanism.

  According to the indoor portable toilet excrement disposal apparatus, the excrement disposal apparatus can be easily attached to the indoor portable toilet instead of the toilet bowl. The portable toilet can be used as a self-processing portable biotoilet with less bad odor.

BEST MODE FOR CARRYING OUT THE INVENTION

The excrement disposal apparatus for indoor portable toilets according to the present invention realizes easy assembly in an existing portable toilet in a short time by using a bucket shape as shown in FIG. Further, manure falling from the toilet seat is reliably received in the container without adhering to the side surface of the container 5a.
Furthermore, the action of the projection 5e provided on the side surface of the storage container 5a activates the microbial decomposition action by efficiently stirring the idling material in the storage container 5a without idling, and the received manure is kept for a predetermined time. Decomposes and disappears within.
Further, since the action of the scraper 5f suppresses the formation of a deposited film on the side surface of the container, which is a source of spoiled odor, there is no need to provide a special deodorizing mechanism.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows an indoor portable toilet used by a person who has some kind of obstacle in walking, such as an elderly person, an injured person, etc., and includes a chair toilet seat 1 and a toilet tub 2. The advantage of the portable toilet is that the user can perform excretion at the bedside without moving to a predetermined toilet. On the other hand, there are drawbacks that an unpleasant stool odor drifts in the living room and that the caregiver has to deal with the excrement accumulated in the toilet 2 as necessary. In order to eliminate such disadvantages of the portable toilet, a portable biotoilet that eliminates feces and urine by utilizing the decomposition action of microorganisms has been devised. As shown in FIG. 2, the portable toilet shown in FIG. 1 and the feces and urine disposal apparatus 4 (4-1, 4-2) having the function of disappearing feces and urine while having the function of the toilet of FIG.

However, as described in 0004 to 0007, the excrement disposal apparatus 4 of the portable biotoilet shown in FIG. 2 is designed to be adapted only to the chair toilet seat 3 of the biotoilet, and is a general commercial product. Incorporation into the indoor portable toilet (a) shown in FIG. 1 was actually difficult.
Therefore, for the indoor portable toilet having various shapes and sizes, what is devised so that it can be incorporated flexibly and easily is the manure processing apparatus 5 for indoor portable toilet of the present invention shown in FIG. The feces and urine treatment device 5 is mounted at an appropriate position on the chair toilet seat 1 in order to reliably receive the toilet bowl function, the agitation function, the temperature control function of the microorganism base material, and the manure falling from the chair toilet seat 1 of the portable toilet. Position adjustment function is provided.

  The toilet bowl function corresponds to the manure container 5a that also serves as a stirring container. The stirring function includes a center shaft 5b, a horizontal stirring blade 5c, an auxiliary stirring blade 5d, an anti-spinning protrusion rod 5e, a septic matter suppressing scraper 5f, and a drive motor 5g. The temperature control function of the microbial base material is composed of a heater 5h, a thermostat 5i, and a heat insulating material 5j. The position adjusting function includes an adjustment bolt 5k for adjusting the height of the storage container and an insulating lock band 5m for preventing horizontal displacement.

One of the features of this embodiment is that the shape of the manure container 5a that also serves as the stirring container shown in FIG. 4 is a cylindrical bucket shape. As shown in FIG. 1, a portable toilet body for indoor use generally has a main body opening 1a imitating a toilet seat shape.
As a procedure for installing the apparatus, first, the manure container 5a shown in FIG. 4 is placed in a space in which the toilet tub 2 below the main body opening 1a of the chair toilet seat 1 of the indoor portable toilet shown in FIG. It is installed and the height is adjusted until it is pressed against the lower surface of the main body opening 1a by the adjusting bolt 5k. And after positioning in the horizontal direction, the urine storage container 5a is secured to the portable toilet body with an insulating lock band 5m in order to prevent horizontal displacement. With the exception of portable toilets having a special shape, as described above, the mounting work can be easily completed in a short time for the majority of indoor portable toilets.
Here, as shown in FIG. 5, the opening of the manure container 5a is designed to be larger than the size of the main body opening 1a.
On the other hand, manure falls from the opening 1c of the toilet seat 1b located on the main body opening 1a. Since the toilet seat opening 1c is smaller than the main body opening 1a, the dropped manure is reliably received in the manure container 5a having an opening larger than the main body opening 1a. As described above, since the opening of the manure container 5a is a circle having a size larger than that of the main body opening 1a, the horizontal positioning of the apparatus is easy. And installation is unnecessary.

  As described above, the excreta treating apparatus 5 according to the present invention shown in FIG. 4 is easy to mount on the indoor portable toilet by taking advantage of the bucket shape of the excreta container 5a, and the required time is short. Therefore, the portable toilet user has no trouble in using the toilet because another toilet must be used during the installation work. Furthermore, there is no separate independent mechanism other than the container that takes the deodorizing mechanism found in other devices as an example of the manure processing apparatus, and all necessary mechanisms are attached and attached to the manure container 5a. The installation of the storage container 5a means the installation of the excrement disposal device 5, so that there is no installation work other than the above, and it fits comfortably in the space under the indoor portable toilet seat, which is a general commercial product.

  Next, the essential problem of the manure processing apparatus is that it has the ability to reliably decompose and eliminate manure. No matter how excellent the portable portable toilet is, if this point is insufficient, it cannot function as a manure processing device. In this respect, the conventional stirring method used in the bucket-shaped container adopted by the present invention cannot be expected to have a sufficient stirring effect due to the existence of a problem that the filling material in the container easily slips as described later. It was difficult to realize the reliable decomposition and disappearance of manure.

The present invention has solved the above problems as follows. As shown in FIG. 4, a center shaft 5b that rotates clockwise (forward rotation), counterclockwise (reverse rotation), or forward / reverse rotation by a drive motor 5g is provided inside the container 5a. One or a plurality of stirring blades 5c are connected to an appropriate position of the center shaft 5b in the horizontal direction.
An appropriate amount of microorganisms that are the filling material in the container 5a, and the chip chips and receiving manure that are the base materials of the microorganisms are agitated by the rotation of the stirring blade 5c.

Here, as a condition for activating the microorganism, it is necessary that the microorganism is sufficiently in contact with air (oxygen). However, as the drying of the filling material, which has been soaked in urine and has a high water content, progressed over time due to stirring, the entire filling material that has become lighter due to moisture flying due to the rotational pressure of the stirring blade 5c rotates. The phenomenon that comes out is embodied. (Hereafter, this phenomenon is called idling of the filler.)
For example, when a flat plate having a sufficient area is rotated instead of the stirring blade 5c, the stirring phenomenon of the filling material does not occur, and the entire filling material simply rotates.
Thus, when the filler is dried by stirring, it easily falls into the idling phenomenon with a slight rotational pressure of the stirring blade 5c.
As a matter of course, since the filler other than the surface layer does not come into contact with air when the filler starts to idle, it is impossible to expect the stool decomposition and disappearance by microorganisms from this point.
Thus, as in the present embodiment, the conventional manure processing apparatus having a cylindrical manure storage container is advantageous in that it can be easily attached to an indoor portable toilet, and can reliably decompose and eliminate manure. The problem that it was difficult to stir the filler sufficient for the purpose was included.

  Therefore, in this embodiment, in order to solve this problem, as shown in FIG. 4, one or more are provided at appropriate positions on the side surface of the manure container 5 a that does not interfere with the stirring blade 5 c and the auxiliary stirring blade 5 d. The filling material idling prevention protrusion bar 5e having an appropriate protrusion length and diameter of 5 mm is provided. With this protruding bar 5e, it becomes possible to prevent the entire filling material from idling,

The dynamic agitation similar to that of the cultivator method described in 1) can be realized, and the complete decomposition and extinction of manure by the sufficient oxygen supply to all the microorganisms inhabiting the filling material became possible.

In this embodiment, as shown in FIG. 6, the heater 5h controlled by the thermostat 5i is connected to the outside of the bottom surface of the storage container 5a for the two purposes of activating microorganisms and promoting water evaporation of manure. It is attached to the outside of the side.
Further, the heater 5h is covered with a heat insulating material 5j to prevent a burn accident of a user or a related person and suppress an increase in power consumption due to an increase in thermal efficiency.

Moreover, a part of the receiving feces is gradually deposited on the side surface of the container 5a to form a deposited film 5p. The deposited film 5p easily comes into contact with, for example, airborne bacteria, and decay proceeds. This decayed deposited film 5p is the cause of the decaying odor.
Therefore, in this embodiment, in order to solve the problem of stool odor or rot odor without providing a special deodorizing mechanism, as shown in FIG. 4, the stool moves while closely contacting the side surface of the stool container 5a. Thus, the scraper 5f is attached to the end of the stirring blade 5c.
By the action of the scraper 5f, the formation of the undegraded fecal deposit film on the side surface of the fecal urine storage container 5a is prevented, and the occurrence of fecal odor or rot odor is suppressed. There is no need to provide a deodorizing mechanism.

It is a perspective view of the conventional indoor portable toilet. It is a perspective view of the conventional indoor self-processing type portable biotoilet. FIG. 10 is a perspective view supplementing necessary materials and work difficulty in incorporating a conventional indoor self-processing portable biotoilet into a conventional indoor portable toilet. It is a perspective view of the excrement disposal container of an example. It is the perspective view which supplements the reliable reception of the manure of the manure processing apparatus in an Example, and the ease of mounting | wearing with respect to the conventional indoor portable toilet, and an associated top view. It is the perspective view and related figure of a heater related part.
