Description

  The present invention relates to a separation-type toilet that separates excreta excreted on the toilet receiving surface of a toilet into a solid component and a liquid component.

  Conventionally, in temporary toilets used in parks, construction sites, etc., manure excreted in toilets can be separated into solids and liquids, and each can be fermented and purified with microorganisms, and the solids can be used as fertilizers. On the other hand, there has been proposed a separation-type toilet that can be used as washing water for flowing a liquid component to a toilet (see Patent Document 1 and Patent Document 2).

  In the separation-type toilet shown in Patent Document 1, a discharge port 31a provided at the bottom of the toilet 31 is formed to spread downward. The liquid content of excreta excreted in the toilet 31 is dropped from the lower end portion along the inner wall surface of the discharge port 31a, and further, a first defecation tube 32 that covers the discharge port 31a from below, The septic tank 11 passes through the inner wall surface of the cylinder 34 into which the second defecation pipe 33 and the second defecation pipe 33 are inserted, from the conical discharge port 34 a formed at the lower end of the cylinder 34 via the urine receiving container 35. Led to. On the other hand, the solid content of manure is dropped from the discharge port 31a, and is guided to the fermenter 3 through the first defecation pipe 32, the second defecation pipe 33, and the third defecation pipe 34 following them.

  The separation type toilet shown in Patent Document 2 includes a discharge pipe extending downward from the toilet 2 and a bottomed cylindrical urine receiving container 4 connected to the discharge port 2a. A defecation tube 5 is formed through the center of the bottom of the container 4. Then, the liquid content of excreta excreted in the toilet 2 is stored on the bottom of the urine receiving container 4 through the discharge pipe of the urinal and the inner wall surface of the urine receiving container 4 and then guided to the urine treatment tank 7. On the other hand, the solid content of manure passes from the toilet 2 through the discharge pipe and the urine receiving container 4 and is dropped from the defecation pipe 5 to the stool processing tank 6.

According to the above-described separation-type toilet, it is possible to perform efficient processing to perform fermentation / purification after separating human waste into solid and liquid, and the liquid is circulated and used as washing water. It has a remarkable effect on environmental conservation.
Japanese Patent No. 3055773 Japanese Patent No. 3534732

  However, in the separation-type toilets described in Patent Documents 1 and 2, since the distance from the toilet bowl to the fermenter 3 and the stool treatment tank 6 for dropping the solid matter from the toilet bowl is long, the toilet installation surface (ground / floor) The height from the surface etc.) to the toilet is inevitably large. As a result, toilets have become larger, leading to increased transportation and installation costs. In particular, when considered as a nursing toilet used beside the bed, the height from the floor surface to the toilet seat could not be adopted because it did not fit around 38 cm, which is optimal for care recipients. .

  Moreover, when throwing away the toilet paper used at the time of a toilet, it is thought that it adheres to the piping provided between a toilet bowl and a fermenter (stool processing tank), but the separation-type toilet described in the above-mentioned patent documents 1 and 2 Then, since piping is long, it is difficult to remove it from the top (toilet bowl side) because it is difficult for hands and cleaning tools to reach. In such a case, the toilet paper attached to the piping can only be washed away with washing water. However, the toilet paper flows along the piping and flows into the urine receiving container, and from the urine receiving container to the septic tank (urine processing tank). There is a risk of clogging the piping that heads.

  In the case where the pipe from the urine receiving container is clogged, the urine receiving container is directly cleaned to remove the clogged one. In order to expose 35, a large-scale operation of removing all of the toilet 31, the first defecation pipe 32, the second defecation pipe 33, and the cylinder 34 is necessary. Moreover, in the separation-type toilet described in Patent Document 2, even when the toilet 2 is removed, the diameter of the upper portion of the stool receiving container 4 is narrowed down, so that the gap with the stool tube 5 is narrow, and the urine receiving container 4 There is still a problem that it is difficult to clean the bottom of the hand because the hand and the cleaning tool do not reach.

  Furthermore, in the toilets described in Patent Documents 1 and 2, the urine receiving container and the stool pipe penetrating vertically through the central portion thereof are separately formed and assembled, and the seam is sealed, Since it is necessary to inspect the sealing property, the manufacturing cost is high, and there is also a risk of liquid leakage from the joint due to deterioration over time. In addition, in Patent Document 1, the discharge port 31a is constricted at the connection portion with the main body of the toilet 31, and in Patent Document 2, the urine receiving container 4 is formed in a pot shape with a constricted upper part. Therefore, it cannot be manufactured with a simple mold, and the manufacturing cost is high from that point.

  In view of the circumstances as described above, the present invention can keep the height from the toilet installation surface to the toilet bowl low, and can be easily removed even when the toilet paper adheres to a pipe provided below the toilet bowl. A separate toilet that can be manufactured at low cost.

FIG. 4 is a diagram for explaining a method of manufacturing the discharge pipe formed at the bottom of the toilet bowl. FIG. 5 is a diagram for explaining the structure and manufacturing method of the solid-liquid separator. In FIG. 1 and FIG. 3, the toilet is depicted in a state of being suspended in the air, but is actually supported and fixed by a support stand, a fixture, or the like (not shown). Further, although the solid-liquid separator is depicted as being exposed, it is actually covered with a side cover or the like (not shown) so that it cannot be seen from the outside during use.

[Separable toilet 1]
Separable toilet 1 as an embodiment of the present invention separates human waste excreted in a toilet into a solid component and a liquid component, and uses it as cleaning water for purifying the liquid component to remove dirt in the toilet. On the other hand, the solid content is fermented and decomposed into carbon dioxide gas and water. As shown in FIG. 1, the separable toilet 1 is mainly provided with a toilet 2 that receives excreted excreta and discharges it in a state of being separated into a solid and a liquid, and is provided and separated immediately below the toilet 2. A solid-liquid separator 3 that separately receives the solid and liquid components, a solid content processing unit 4 that is provided immediately below the solid-liquid separator 3 to drop the solid content of manure, and a liquid content of manure The liquid component processing unit 5 is guided and a cleaning water tank 6 for storing the cleaning water obtained by the purification process in the liquid component processing unit 5. In addition, P1 is a pump for sending washing water from the liquid processing unit 5 to the washing water tank 6, and P2 is a pump for ejecting the washing water stored in the washing water tank 6 into the toilet bowl 2.

[Toilet 2]
The toilet bowl 2 is a western-style toilet bowl made of synthetic resin, and as shown in FIGS. 2 and 3, a main body portion 21 having a bowl-shaped inner surface 21a to form a toilet bowl and forming a toilet bowl body, The rim part 22 formed integrally over the entire periphery of the upper edge part 21b, pipe-like washing water ejection parts 23 and 24 arranged along the upper edge part 21b, and the bottom part of the bottom part 21c And a discharge pipe 25 formed continuously. The washing water ejection portions 23 and 24 both extend from the rear side in the front-rear direction of the main body portion 21 (the lower side in FIG. 2) toward the front, but the washing water ejection portion 24 makes a U-turn at the tip 24a. Therefore, the washing water ejection portions 23 and 24 are adapted to eject washing water in the same clockwise direction.

  The rim portion 22 is a support base for supporting the toilet seat 26 (shown by a one-dot chain line in FIG. 3), and also prevents the wash water ejected from the wash water ejection portions 23 and 24 from jumping out of the toilet 2. In order to form a waterproof wall covering from above, the upper edge portion 21b of the main body portion 21 is formed so as to protrude toward the inner surface 21a side. The washing water ejection portions 23 and 24 cause the washing water stored in the washing water tank 6 to be ejected from the upper edge portion 21b along the circumferential direction of the toilet bowl 2 by the operation of the pump P2, and the washing water is along the inner surface 21a. A clockwise spiral flow (indicated by a two-dot chain line arrow in FIGS. 2 and 3) is formed. By combining the flows from the washing water jetting portions provided at a plurality of locations in the circumferential direction of the toilet bowl, the inside of the toilet bowl can be washed strongly and uniformly.

[Discharge pipe 25]
As shown in FIG. 3, the discharge pipe 25 is provided integrally with the bottom 21 c of the main body 21, and is continuous with the throttle 25 a that has the smallest diameter in the vertical direction and the upper part of the throttle 25 a. The upper extension part 25b is formed, and the lower extension part 25c is formed continuously with the lower part of the throttle part 25a. The upper extension portion 25b is formed so as to spread in a trumpet shape upward from the throttle portion 25a, and the lower extension portion 25c is formed in a trumpet shape downward from the throttle portion 25a. The inner surface of the bottom 21c is formed continuously without a step.

  As described above, in the excreta excreted on the inner surface 21a of the toilet bowl 2, the liquid component is reliably transferred from the bottom portion 21c to the curved inner wall surfaces of the upper extension portion 25b, the throttle portion 25a, and the lower extension portion 25c. The solid component is dropped downward from the lower edge portion of the discharge pipe 25, and the solid content is regulated when passing through the throttle portion 25a, and then linearly falls as it is. Therefore, as will be described later, a liquid receiving part 31 that receives liquid directly dropped from the lower edge of the lower extension 25c and a solid that directly falls from the throttle 25a are disposed below the discharge pipe 25 of the toilet bowl 2. By providing the solid-liquid separator 3 including the solid content receiving part 32 to receive, the liquid content and the solid content can be separated and recovered.

  From the discharge pipe 25, the washing water ejected from the washing water ejection portions 23, 24 is also discharged together with the manure, but is ejected from the upper edge portion 21b along the circumferential direction of the toilet, and the swirl flow is generated. As a result, the inner surface of the discharge pipe 25 is reliably transmitted by the action of the centrifugal force, and solid-liquid separation is performed more efficiently than the case of simply flowing from top to bottom.

  The discharge pipe 25 is not integrally formed from the beginning in the manufacturing process, but is formed in a state of being vertically divided by the throttle portion 25a. Specifically, as shown in FIG. 4, the bottom part of the main body 21 of the toilet bowl and the upper pipe part 251 of the discharge pipe 25 divided vertically by the throttle part 25a are integrally formed, and the discharge pipe divided vertically. 25, the lower pipe part 252 is formed independently, and then the divided parts of the upper pipe part 251 and the lower pipe part 252 are fixed together by an adhesive or the like. As a result, the structure of the molding die is simplified and can be easily manufactured as compared with the case of integral molding from the beginning. Note that fitting steps 251b and 252b for positioning each other are formed on the lower end surface 251a of the upper tube portion 251 and the upper end surface 252a of the lower tube portion 252.

[Solid-liquid separator 3]
The solid-liquid separator 3 is formed of a synthetic resin separately from the toilet 2 described above, and is provided so as to be separable from the toilet 2, and as shown in FIG. The container-shaped liquid receiving part 31 that is opened and covers the lower extension part 25c from below, and the upper part of the bottom part 31a of the liquid receiving part 31 are formed so as to project at a position corresponding to the upper restricting part 25a. And a cylindrical solid portion receiving portion 32. More specifically, as shown in FIG. 5A, the solid-liquid separator 3 includes a frame-shaped bottom plate that forms the bottom 31a of the liquid receiving portion 31, and a liquid that extends upward from the outer peripheral edge of the bottom plate. A straight-tube large-diameter cylindrical body that forms the outer peripheral wall 31b of the fraction receiving part 31, and an inner peripheral wall 31c of the liquid part receiving part 31 and an outer peripheral wall 32a of the solid part receiving part 32 extending upward from the inner peripheral edge of the bottom plate. A straight tubular small-diameter cylindrical body is integrally formed. The bottom 31a is provided with a liquid outlet 31d, which is also formed in a straight tube shape, and protrudes downward to facilitate pipe connection with the liquid processing unit 5. .

  Since the solid-liquid separator 3 employs the structure as described above, there is no so-called undercut, and as shown in FIG. 5B, the upper mold 71 and the lower mold 72 have a simple structure without a slide core or the like. The upper and lower split mold 7 can be easily molded. In addition, since the liquid receiving portion 31 and the solid receiving portion 32 are integrally formed, there is no seam between them, so that the liquid processing receiving portion 31 does not leak from the liquid receiving portion 31 during assembly. This eliminates the need for an inspection for checking for defective seals, reduces manufacturing costs, and eliminates the need for worrying about leakage due to aging.

  Moreover, since the toilet bowl 2 provided above is separable from the solid-liquid separator 3, the liquid receiving part 31 can be exposed and cleaned by removing the toilet bowl 2. Therefore, for example, even when toilet paper or the like may be clogged in the liquid content receiving portion 31, the toilet 2 can be removed and easily removed. Furthermore, since the outer peripheral wall 31b and the inner peripheral wall 31c extend straight upward as described above, the liquid receiving portion 31 can directly view the entire bottom surface 31a from the upper opening, and can easily perform the cleaning work. Is.

  Since the liquid receiving part 31 is provided so that the upper part is opened and the lower extension part 25c is covered from below, the liquid part receiving part 31 directly receives the liquid part dropped from the lower edge part of the lower extension part 25c, while the bottom part 31a receives the liquid part. Since the liquid component discharge port 31d is formed, the liquid component once stored can be guided from the liquid component discharge port 31d to the liquid component processing unit 5 disposed below. In addition, the solid content receiving unit 32 can guide the solid content falling from the throttle unit 25a directly to the opening 4a of the solid content processing unit 4 disposed below. In order to reliably receive the solid component falling from the toilet bowl by the solid component receiving unit 32, the inner diameter thereof is set larger than the inner diameter of the throttle unit 25a.

[Solid content processing unit 4]
The solid content processing unit 4 is a fermentation processing tank in which microorganisms for fermenting the solid content separated from manure are present, and sawdust and cedar chips that absorb moisture contained in the solid content are placed. As shown in FIG. 3, a stirring screw 41 is supported in the interior. The stirring screw 41 is rotated by a motor M provided outside, so that solids and sawdust are mixed together, and air necessary for the activity of microorganisms is included in the mixture to promote a fermentation process. The solid content is fermented and decomposed into water and carbon dioxide.

  On the upper surface of the solid content processing unit 4, an opening 4 a that is formed so as to correspond to the solid content receiving unit 32 and that receives the solid content dropped from the solid content receiving unit 32 is formed. The opening 4a is closed by a lid 42 that is pivotally supported by a pivot support shaft 42a provided at the peripheral edge thereof. The lid 42 is held in a state in which the opening 4a is closed (indicated by a solid line in FIG. 3) by a spring (not shown) attached around the rotation support shaft 42a. Is opened by the weight when it is dropped (the state indicated by the one-dot chain line in FIG. 3), and the solid content falls into the solid content processing unit 4 and is closed again when the weight is released. It has become.

  Therefore, the odor due to the solid content of the manure dropped in the solid content processing unit 4 is confined in the solid content processing unit 4, and the odor leaking outside the toilet can be reduced. Further, since the lid 42 is automatically rotated and opened by the weight of the solid, there is no fear of forgetting to close after the toilet.

[Liquid component processing unit 5]
The liquid component processing unit 5 is a purification treatment tank in which microorganisms that purify the liquid component separated from manure are resident, and is configured to decompose and remove organic substances contained in the liquid component. The purified liquid component is used as washing water for washing the filth adhered to the toilet bowl 2.

[Washing tank 6]
The washing water tank 6 is connected to the liquid component processing unit 5 through a pipe in the middle of which the pump P1 is disposed. The liquid component purified by the liquid component processing unit 5 is pumped up by the pump P1 and stored as cleaning water. It is a liquid tank. The washing water stored in the washing water tank 6 is ejected vigorously along the circumferential direction of the toilet bowl, as described above, by operating the pump P2.

[Features of separable toilet 1]
In the separation-type toilet according to the present embodiment, the discharge pipe 25 for separating the urine is integrally provided on the bottom 21c of the main body 21 of the toilet bowl, and the solid-liquid separator 3 is provided immediately below. The dimension in the height direction up to the solid component processing unit 4 and the liquid component processing unit 5 disposed below the solid-liquid separator 3 can be reduced. Therefore, although it is a separation-type toilet, the vertical dimension can be made compact, and as a result, it is easy to suppress transportation / installation costs or to use as a nursing toilet.

  Moreover, since the piping distance from the main body part 21 of the toilet bowl to the opening 4a of the solid content processing unit 4 is short, the toilet paper thrown away in the toilet bowl may adhere to the piping on the way to the solid content processing unit 4. Even if it adheres, it can be easily removed because it is easy to reach by hand or cleaning tool.

[Modification of the above embodiment]
In the above embodiment, in order to ensure the workability of transportation and installation, the toilet 2 and the solid separator 3 are formed of synthetic resin so as to make the separation-type toilet lightweight, but not limited to this, You may make it form with other materials, such as a metal. Of course, the body part 21 and the upper pipe part 251 of the toilet bowl 2 may be formed of a synthetic resin, and only the lower pipe part 252 may be formed of a metal, for example.

  In the above embodiment, the pump P2 is used to eject the washing water from the washing water ejection portions 23, 24 vigorously. However, if the position of the washing water tank 6 can be increased, only the gravity is used without using the pump. You may make it erupt naturally. Further, the washing water jetting portions are not necessarily provided at a plurality of locations, and may be provided at only one location.

  In the above embodiment, the solid content receiving portion 32 of the solid-liquid separator 3 is protruded only from the bottom portion 31a of the liquid content receiving portion 31 to the upper surface side, but may be further protruded to the lower surface side. The bottom 31a of the liquid receiving part 31 is circular, but a quadrilateral or other shape may be adopted.

  In addition, the present invention is not limited to the above-described embodiment, and can be appropriately modified without departing from the gist of the invention.
