Description

  The present invention relates to a toilet facility.

  FIG. 19 of Patent Document 1 discloses a conventional toilet facility. This toilet facility is provided separately from a solid-liquid separation device that separates human waste from solid stool and liquid urine, a stool tank that stores the separated stool, and a stool tank. And a urine tank into which the separated urine flows. This toilet facility prevents the urine from flowing into the stool tank by separating the stool tank and the urine tank. For this reason, the water | moisture content of the stool stored in the stool tank does not become excessive, and the stool stored in the stool tank can be favorably fermented with the aerobic microorganism. In addition, this toilet facility includes an exhaust pipe that communicates with the stool tank and the urine tank and discharges odors in the stool tank and the urine tank. The exhaust pipe has a fan. For this reason, this toilet equipment can drive the fan of an exhaust pipe and forcibly discharge odors from the stool tank and the urinal tank to the outside of the toilet room. For this reason, this toilet equipment can prevent the odor in the stool tank and the urine tank from spreading into the toilet room, making it difficult to feel the odor in the toilet room.

JP 2011-167679 A

  However, in the above conventional toilet facilities, the odor discharged to the outside of the toilet room via the exhaust pipe may stay in a predetermined place outside the toilet room depending on the surrounding building conditions, weather conditions such as temperature, wind direction, etc. There is. In this case, the odor will be felt at that location.

  This invention is made | formed in view of the said conventional situation, Comprising: It is set as the problem which should be solved to provide the toilet installation which can suppress the spreading | diffusion of an odor.

The toilet equipment of the present invention separates human excrement into stool that is solid and urine that is liquid, and the separated urine and the solid-liquid separation device from which the wash water that flows in at the time of cleaning flows out downward,
A peripheral wall that rises from a peripheral edge, and is disposed below the solid-liquid separator, and a tray into which the separated urine and the washing water flow,
A communication pipe communicating with the tray, and a tank for storing the urine flowing out of the tray through the communication pipe;
When the wash water flows into the tray more than the stool separated by the solid-liquid separator and the flow rate that can flow through the communication pipe (the amount of water that flows per unit time: the same applies hereinafter). And a toilet tank for storing the washing water overflowing over the water.

  This toilet facility stores urine separated from stool in a tank. For this reason, the ammonia odor generated when bacteria decompose the urea in the urine stays in the tank. For this reason, it can suppress that the ammonia odor which generate | occur | produces when the urea in a urine is decomposed | disassembled by bacteria spread | diffuses outside. Further, in this toilet facility, the wash water flowing into the tray during cleaning overflows the surrounding wall and is stored in the toilet tub. For this reason, this toilet equipment can cover the stool stored in the toilet bowl with the washing water, and can suppress the odor generated from the stool from diffusing to the outside.

  Therefore, the toilet facility of the present invention can suppress odor diffusion.

It is the schematic which shows the toilet installation of an Example. It is a disassembled perspective view which shows the solid-liquid separator of an Example, and a saucer. It is sectional drawing which shows the state which the extrusion member of the Example moved to one discharge end of a separation plate. It is a top view which shows the state which the extrusion member of the Example moved to one discharge end of a separation plate. It is sectional drawing which shows the state which the extrusion member of the Example moved to the other discharge end of the separation plate. It is a top view which shows the state which the extrusion member of the Example moved to the other discharge end of the separation plate.

  A preferred embodiment of the present invention will be described.

The solid-liquid separator is
An opening is provided for receiving human excrement on the upper surface, dropping the stool into the stool from the discharge end, which is an end, and passing the urine and the washing water into the receiving tray disposed below. Separating plate,
A conveying device for pushing out the stool remaining on the separation plate from the discharge end;
A side plate rising from an end other than the discharge end of the separation plate;
An opening / closing lid for opening and closing a discharge port formed by the end portion of the side plate and the discharge end may be provided.

  In this case, since the solid-liquid separator surrounds the space where the excrement falls on the separation plate by the side plate and the opening / closing lid, the odor in the toilet bowl flows into the space where the excrement falls on the separation plate. Can be difficult. For this reason, it can suppress that the odor in a toilet bowl enters into the toilet room which attached this solid-liquid separation apparatus under the floor. In addition, when the stool is pushed out from the discharge end of the separation plate by the transport device, the opening / closing lid can open the discharge port and drop the stool from the discharge end into the stool.

  The communication pipe may include a check valve that allows a flow from the tray to the tank and prevents a flow in the opposite direction. In this case, it is possible to prevent the ammonia odor from flowing out from the tank toward the tray. For this reason, this toilet facility can suppress ammonia odor from flowing into the toilet room.

  Next, an embodiment in which the toilet facility of the present invention is embodied will be described with reference to the drawings.

<Example>
The toilet equipment of an Example is provided with the non-flush toilet 1, the solid-liquid separation apparatus 10, the receiving tray 70, the tank 80, and the toilet bowl 90, as shown in FIG. The non-flush toilet 1 includes a toilet body 2 and a toilet seat 3 and a toilet lid 4 attached to the upper surface of the toilet body 2. The toilet body 2 has a toilet bowl portion 2A that is open at the top and bottom, and the lower opening forms a toilet outlet 2B. The toilet body 2 is fixed on the floor member F in a state where the toilet outlet 2B is inserted into an opening provided in the floor member F of the toilet room R. When the user of the non-flush toilet 1 uses the stool, the excrement (stool and urine) dropped from the toilet outlet 2B is fixed on the separation plate 20 of the solid-liquid separation device 10 described below fixed below the floor member F. Fall.

  As shown in FIG. 2, the solid-liquid separation device 10 includes a separation plate 20, a side plate 30, a transport device 40, and an opening / closing lid 60. The separation plate 20 is a flat plate having a rectangular shape in plan view, and is disposed in a horizontal state below the toilet outlet 2B. The separation plate 20 has discharge ends 21 </ b> A and 21 </ b> B that push out the stool remaining on the separation plate 20 by the conveying device 40 at both ends on the short side. The separation plate 20 is provided with a plurality of slit-shaped openings 22 parallel to the long sides. Each opening 22 extends linearly between the discharge ends 21 </ b> A and 21 </ b> B of the separation plate 20.

  The separating plate 20 includes a continuous side plate 30 that rises vertically upward from both ends of the long side other than the discharge ends 21A and 21B, and an upper plate 32 that extends horizontally from the upper end of each side plate 30 to the outside. Provided. The upper plate 32 has locking plates 36 fixed to both end portions of the separating plate 20 in the long side direction via spacers 34.

  The conveying device 40 includes a driving device 47 that reciprocates the pushing member 41, the scraper member 43, the removing member 45, and the pushing member 41 between the discharge ends 21 </ b> A and 21 </ b> B of the separation plate 20. The push member 41 includes a first push plate 41A and a second push plate 41B.

  The first extrusion plate 41A is a horizontally long rectangular flat plate and has a pair of support plates 42 formed continuously at both ends. Each support plate 42 is a flat plate orthogonal to the first extrusion plate 41A. In each support plate 42, a portion bent continuously from the first extrusion plate 41A is inclined downward from the upper end portion toward one discharge end 21A of the separation plate 20 (lower right end portion in FIG. 2). One inclined side 42A is formed. Each support plate 42 has a second inclined side 42B inclined downward from the upper end of the first inclined side 42A toward the opposite side (the direction of the upper left discharge end 21B in FIG. 2). Each support plate 42 includes a bottom side extending inward in the horizontal direction from the lower ends of the first inclined side 42A and the second inclined side 42B, and a horizontally elongated convex part (45A) projecting downward from the bottom side at the center. Have. Each support plate 42 is provided with a through hole 42C at the upper end. A shaft member 42D that pivotally supports a second push-out plate 41B described later is inserted through the through-hole 42C.

  The first extrusion plate 41A extends between the opening portions 22 (both end opening portions 22S) that are closest to the side plates 30 that are vertically raised from both end portions that form the long side of the separation plate 20. For this reason, each support plate 42 can move along the both-end openings 22S in a state where the convex portions (45A) are inserted through the both-end openings 22S. The first extrusion plate 41 </ b> A is disposed on the separation plate 20 along the first inclined side 42 </ b> A of the support plate 42. For this reason, the first extrusion plate 41A is inclined downward toward one discharge end 21A of the separation plate 20 (the lower right end portion in FIG. 2). The first extrusion plate 41A can reciprocate between the discharge ends 21A and 21B of the separation plate 20 together with the support plate 42.

  The second extruded plate 41B is a horizontally-oriented rectangular substantially flat plate, and the lateral direction is formed slightly longer than the first extruded plate 41A. In the second extruded plate 41B, the upper side and the upper part of the left and right sides are bent at right angles in the same direction. The second extrusion plate 41B is provided with through holes 41C in the bent portions of the left and right sides. The second extruded plate 41B has a shaft member 42D inserted into the through hole 41C and is pivotally supported by the support plate 42, and the back surface is in contact with the second inclined side 42B of the support plate 42. Therefore, the second extrusion plate 41B is disposed so as to be inclined downward toward the other discharge end 21B of the separation plate 20 (the upper left end portion in FIG. 2).

  Thus, the pushing member 41 is formed in a substantially chevron shape above the separation plate 20 by the first pushing plate 41A and the second pushing plate 41B. For this reason, even if excrement falls on the extrusion member 41, the excrement does not stay on the extrusion member 41, but falls on the separation plate 20 along the first extrusion plate 41A and the second extrusion plate 41B.

  The scraper member 43 is a flat plate extending between the both side plates 30 of the separation plate 20 and is placed on the separation plate 20. The scraper member 43 is formed in a saw blade shape with side portions 43A parallel to both discharge ends 21A and 21B of the separation plate 20. In addition, when the scraper member 43 is placed on the separation plate 20, slit-like openings 44 are provided at positions corresponding to the openings 22 of the separation plate 20.

  The convex portion of the support plate 42 constitutes a removing member 45A. The other removing members 45B and 45C are formed of a rectangular flat plate having a flange 45D whose upper portion extends in the lateral direction. Each removing member 45 is provided with a through hole 45E through which the connecting member 46 is inserted. The support plate 42 has a bottom that is locked to the edge of the opening 44 of the scraper member 43, and a convex portion that is a removal member 45 </ b> A is inserted through the opening 44 of the scraper member 43 and both ends of the separation plate 20. And protrudes below the separation plate 20. Further, the other removal members 45B and 45C have the flange portion 45D engaged with the edge of the opening 44 of the scraper member 43, and are inserted through the opening 44 of the scraper member 43 and the opening 22 of the separation plate 20. Projecting below the separation plate 20. Of the other removing members 45B and 45C, the pair of removing members 45B arranged at a distance from each other are provided with two bolt holes 45F for connecting to both ends of a connecting member 49 described later of the driving device 47. The other removing members 45B and 45C are formed such that both upper corners of the flange 45D are in contact with the back surface of the first extruded plate 41A or the back surface of the second extruded plate 41B.

  Each removing member 45 is connected by a rod-like connecting member 46 inserted through the through hole 45E below the separation plate 20. The connecting member 46 is attached with stopper members 46A at both ends so as not to come out of the through hole 45E.

  Each removing member 45 can reciprocate along each opening 22 while being inserted into each opening 22 of the separation plate 20. Further, each removing member 45 is integrated with the first extrusion plate 41A and the second extrusion plate 41B via the connecting member 46 and the support plate 42. For this reason, the 1st extrusion board 41A, the 2nd extrusion board 41B, the scraper member 43, and each removal member 45 can reciprocate between both discharge end 21A, 21B of the separation board 20 together.

  As shown in FIGS. 1 to 6, the drive device 47 includes a push-pull cable 48, a connection member 49, and a lever member 50. The push-pull cable 48 includes a cylindrical outer casing 48A provided at each of both ends, a rod-shaped rod member 48B that is slidably accommodated in each outer casing 48A, and enters and exits from the tip of the outer casing 48A. An inner cable 48C for connecting the rear ends of the rod member 48B.

  As shown in FIG. 2, the connecting member 49 is a horizontally long flat plate, and both end portions are bent at right angles in the same direction. The connection member 49 is provided with two through holes 49A through which bolts for connecting the pair of removal members 45B are inserted at both bent end portions. The connecting member 49 connects the tip end portion of one rod member 48B of the push-pull cable 48 to the center portion, and connects a pair of removal members 45B to both end portions.

  As shown in FIG. 1, the lever member 50 includes a rod-shaped lever main body 51 and an operation box 52. The lever main body 51 is connected to the tip of the other rod member 48B of the push-pull cable 48. The operation box 52 has a straight guide hole 53 through which the lever body 51 is inserted. The lever main body 51 can reciprocate along the guide hole 53. The operation box 52 is fixed to the wall surface of the toilet room R in which the non-flush toilet 1 is installed so that the lever body 51 can be operated in the horizontal direction along the guide hole 53.

  As shown in FIG. 2, the solid-liquid separation device 10 has a strip-shaped connection plate 61 that connects upper ends of both side plates 30 that are continuous with the discharge ends 21 </ b> A and 21 </ b> B of the separation plate 20. Both ends of the connecting plate 61 are bent at right angles in the same direction, and are bolted to the upper ends of the both side plates 30. The connecting plate 61 forms a discharge port X (see FIGS. 3 and 5) together with the ends of the side plates 30 and the discharge ends 21 </ b> A and 21 </ b> B of the separation plate 20. The connecting plate 61 is attached with an open / close lid 60 formed of a flexible rubber plate in a suspended state. The opening / closing lid 60 is sized to close the discharge port X, and is normally suspended from the connecting plate 61 with the discharge port X being closed. In this state, since the solid-liquid separator 10 surrounds the space where the excrement falls on the separation plate 20 by the side plate 30 and the opening / closing lid 60, the solid-liquid separation device 10 is in the space where excrement falls on the separation plate 20. It is possible to make it difficult for the odor in the toilet tank 90 to flow. For this reason, it can suppress that the odor in the toilet bowl 90 enters into the toilet room R which attached this solid-liquid separation apparatus 10 under the floor. Further, as shown in FIGS. 3 to 6, the opening / closing lid 60 is bent and bent to open the discharge port X when the conveying device 40 pushes the stool remaining on the separation plate 20 from the discharge ends 21 </ b> A and 21 </ b> B. The stool can be dropped into the toilet tank 90 from the discharge ends 21A and 21B.

  As shown in FIGS. 1 to 3 and 5, the tray 70 has a peripheral wall 71 that is substantially the same shape and size as the separation plate 20 in a plan view and rises from the peripheral edge. The tray 70 has four hanging pieces 72 extending upward from both ends of the peripheral wall 71 on the short side. The tray 70 is arranged below the separation plate 20 by connecting each suspension piece 72 to both ends of each connection piece 21C bent vertically downward from both discharge ends 21A and 21B of the separation plate 20. The tray 70 is connected to a communication pipe 73 communicating with the tank 80 at the lower part of one peripheral wall 71 on the short side.

  As shown in FIGS. 3 to 6, the floor member F has a pair of rail members 100 attached to the lower surface thereof extending in parallel with the toilet bowl outlet 2 </ b> B interposed therebetween. The solid-liquid separation device 10 to which the receiving tray 70 is attached is suspended and fixed slidably on the lower surface of the floor member F by locking the outer end portions of the locking plate 36 to the rail member 100. For this reason, the solid-liquid separator 10 and the tray 70 can be easily removed for installation and maintenance.

  As shown in FIG. 1, the communication pipe 73 includes a check valve 73 </ b> V at an intermediate portion. The check valve 73V allows the flow from the tray 70 to the tank 80 and prevents the flow in the reverse direction. The tank 80 is connected to the downstream end of the communication pipe 73, and is disposed separately from the toilet tub 90 outside the toilet room R where the non-flush toilet 1 is installed.

  The toilet bowl 90 is formed using the entire floor under the toilet room R. That is, the toilet tank 90 is formed to be surrounded by the floor foundation 91, the side wall 92 rising from the periphery of the floor foundation 91, and the floor member F. Thus, the stool tank 90 is provided below the position where the stool is pushed out from the separation plate 20 of the solid-liquid separator 10. The side wall 92 communicates with a discharge passage 93 that is used when the stool and the washing water stored in the toilet tank 90 are sucked and discharged by a vacuum car. The discharge passage 93 is closed by a lid member 94 except when the stool and wash water stored in the toilet tank 90 are sucked and discharged by a vacuum car.

  The toilet tank 90 communicates with the outside by an exhaust pipe 95 that rises through the floor member F. The exhaust pipe 95 has a fan (not shown) and can forcibly exhaust the air in the toilet tank 90.

  The toilet equipment having such a configuration can store excrement (stool and urine) excreted by the user of the non-flush toilet 1 as shown below.

  When the user of the non-flush toilet 1 uses the stool, the excrement (stool and urine) dropped from the toilet outlet 2B falls on the separation plate 20. Of excreta received on the upper surface of the separation plate 20, stool that is a solid component remains on the separation plate 20, and urine that is a liquid component passes through each opening 22 downward. Thus, the solid-liquid separator 10 can separate human excrement into stool and urine by the separation plate 20.

  The urine separated by the solid-liquid separator 10 flows into the tray 70. The urine that has flowed into the tray 70 flows out through the communication pipe 73 and is stored in the tank 80. As described above, since this toilet facility stores urine in the tank 80, ammonia odor generated by the bacteria decomposition of urea in the urine stays in the tank 80. Further, since the communication pipe 73 includes the check valve 73V, the ammonia odor can be prevented from flowing out from the tank 80 toward the tray 70. For this reason, this toilet facility can suppress the ammonia odor from flowing into the toilet room R. That is, the ammonia odor can be prevented from diffusing outside.

  As shown in FIG. 1, when the lever main body 51 is far from the non-washable toilet 1, the user of the non-washable toilet 1 moves the lever main body 51 away from the non-washable toilet 1 after stool. Move from one side to the other (from left to right in FIG. 1). As a result, the rod member 48B on the operation box 52 side is pushed into the outer casing 48A, and the rod member 48B on the solid-liquid separator 10 side is pushed out from the outer casing 48A as shown in FIGS. For this reason, the pushing member 41 of the conveying apparatus 40 moves to one discharge end 21A of the separation plate 20 (right side in FIG. 3).

  At this time, the saw blade-shaped side portion 43A located on the front side in the moving direction of the scraper member 43 scoops out the stool on the separation plate 20, and each removal member 45 is attached to each opening portion 22 or each opening portion. The first extrusion plate 41A pushes out the stool remaining on the separation plate 20 from one discharge end 21A of the separation plate 20 while removing the stool that closes 22. At this time, the opening / closing lid 60 is bent and bent to open the discharge port X, and the stool falls into the toilet tank 90 from one discharge end 21A.

  When the lever main body 51 is closer to the non-flush toilet 1, the user of the non-flush toilet 1 moves the lever main body 51 away from the closer to the non-flush toilet 1 after the stool. (In FIG. 1, from right to left). As a result, the rod member 48B on the operation box 52 side is pulled out from the outer casing 48A, and the rod member 48B on the solid-liquid separator 10 side is pulled into the outer casing 48A as shown in FIGS. For this reason, the pushing member 41 of the transport device 40 moves to the other discharge end 21B (left side in FIG. 5) of the separation plate 20.

  At this time, the saw blade-shaped side portion 43A located on the front side in the moving direction of the scraper member 43 scoops out the stool on the separation plate 20, and each removal member 45 is attached to each opening portion 22 or each opening portion. The second extrusion plate 41B pushes out the stool remaining on the separation plate 20 from the other discharge end 21B of the separation plate 20 while removing the stool that closes 22. At this time, the opening / closing lid 60 is bent and bent to open the discharge port X, and the stool falls into the toilet tank 90 from the other discharge end 21B.

  When this toilet equipment is cleaned to remove stool attached to the toilet bowl 2A of the toilet body 2 of the non-flush toilet 1, the pushing member 41, and the upper surface of the separation plate 20, a bucket or the like is used. The washing water is poured into the toilet bowl 2A at a stretch. Then, the washing water flows through the opening 22 of the separation plate 20 and flows into the tray 70 disposed below. Since the wash water introduced into the toilet bowl portion 2A using a bucket or the like flows into the tray 70 at a stretch, the flow rate exceeds the flow rate that can flow through the communication pipe 73, and the wash water passes through the peripheral wall 71 of the tray 70. It overflows, flows down into the toilet tank 90, and is stored. For this reason, as shown in FIG. 1, this toilet equipment can cover the stool stored in the toilet tank 90 with the wash water, and can suppress the odor generated from the stool from diffusing to the outside.

  Therefore, the toilet facility according to the embodiment can suppress odor diffusion.
