Abstract

PROBLEM TO BE SOLVED: To provide a waterless urinal system having a function of reducing offensive odor and a function of preventing adhesion of urolith.SOLUTION: The waterless urinal system comprises: a cartridge 1, at a lower part of a urinal body 20, that includes a trap 2 for storing liquid to a prescribed water level, a lid 3 covering the trap 2 and formed with an inflow port 31 for introducing the liquid to the trap 2, and opening/closing means 4 for opening and closing the inflow port 31; and a bacteria-derived detergent 5 that is placed on the upper part of the cartridge 1 and consumes ammonia generated from urea contained in the liquid.

Description

  The present invention relates to a male urinal system, and more particularly to an anhydrous urinal system that does not use wash water to drain urine.

  In a general men's flush urinal, the urine is discharged by flowing the wash water regularly or before and after use, but the urea contained in the urine is decomposed by the germs propagated through the wash water, The decomposed urea may be converted to ammonia. This ammonia causes odor. Furthermore, when ammonia is generated in large quantities, the liquidity shifts to alkaline. Therefore, calcium ions dissolved in urine are transformed into poorly soluble calcium compounds (calcium carbonate, calcium phosphate, etc.) and adhere as so-called urine stones. . If a large amount of urine stone accumulates, the drain pipe or the like may become clogged, and it requires a large cost to remove it. In addition, since the urine stone itself is porous, it is easy for bacteria to accumulate in the place where the urine stone adheres, which may cause dirt and odor.

  In recent years, anhydrous urinals that do not use washing water for urine discharge have been proposed from the viewpoint of saving water resources. For example, Patent Document 1 discloses a deodorant trap (cartridge) for an anhydrous toilet, and this deodorant trap closes a pan to be inserted into a urinal, a lid covering the pan, and an opening of the lid. Float is provided to prevent odor from leaking to some extent. In addition, unlike ordinary flush toilets, the wash water is not used every time it is used, so it is possible to reduce the growth of germs through the remaining wash water and the production of urinary stones derived from calcium in the wash water. it can.

JP 2002-513667 A

  However, even in the deodorization trap described in Patent Document 1, miscellaneous bacteria propagate through the water contained in the urine itself, so that the generation of ammonia cannot be completely suppressed. The generated ammonia caused odor, and the odor leaked when the opening was opened to urine. In addition, urinary stones are generated by ammonia, which may cause urinary stones to adhere to the inner wall of the urinal, the upper and inner portions of the deodorization trap, the drain pipe, and the like.

  Furthermore, when using a float that closes the lid opening as an odor blocking device, it is necessary to open the opening to allow urine to flow in use, and in other cases to close the opening to block the odor. It has been found that the mass and buoyancy of the float need to be set appropriately for accurate opening and closing of the breaker. Further, when urine stones adhere to the float, the mass of the float changes, so the difference between the mass of the float itself and the buoyancy of the float may change. In this case, the opening cannot be opened and closed accurately, and there is a risk that a gap will be formed in the opening and odor may leak out, or urine may be blocked on the upper surface of the lid.

  Further, in this deodorizing trap, the hair that has fallen off may remain on the top surface of the trap, and the appearance is not preferable. Further, such a deodorizing trap is preferably replaced periodically for hygiene purposes, but there is a problem that it is difficult for the user to determine the replacement time.

  The present invention has been made in view of the above problems, and provides an anhydrous urinal system that solves at least one of the above problems.

  In order to solve the above-mentioned problems, the anhydrous urinal system of the present invention includes a trap that stores liquid up to a predetermined water level, a lid that covers the trap and has an inlet that leads the liquid to the trap, and an inlet that is open. And an opening / closing means for closing, and a cleaning agent derived from bacteria that is placed above the cartridge and consumes ammonia generated from urea contained in the liquid.

  The anhydrous urinal system is detachably provided on the lid, and includes a cover unit on which the cleaning agent is placed. The cover unit is placed on the receiving tray provided with a recess on which the cleaning agent is placed, and on the recess. It is preferable to have a cover provided with a micropore covering the cleaning agent.

  In the anhydrous urinal system, a gap is preferably provided between the cover unit and the lid. The opening / closing means may be a float that pushes up and closes the inflow port from the lower side of the inflow port using a difference force between buoyancy received from the liquid stored up to a predetermined water level and gravity due to its own weight. Further, the opening / closing means may be a float that pushes down and closes the inflow port from above the inflow port, using a difference force between buoyancy received from the liquid stored up to a predetermined water level and gravity due to its own weight.

  The float is preferably provided such that the absolute value of the difference between buoyancy acting on itself and gravity is in the range of 0 to 1.00 N. Moreover, it is preferable that the said float has a braking means which brakes the operation | movement of floating or sinking using the liquid from the inflow port, or a part of liquid stored in the trap. Furthermore, it is preferable that the float is formed so that a part of the body portion is narrowed.

  In the anhydrous urinal system, the opening / closing means may be an elastic membrane valve that pushes up and closes the inlet from below the inlet using its own elastic force. The elastic membrane valve is preferably provided so that its elastic force is in the range of 0 to 1.00N.

  Further, in the anhydrous urinal system, it is preferable that at least a part of the lid is formed of an adhesive member and abuts on the cartridge built-in portion. The member having adhesiveness may be composed of an O-ring or a rubber cap.

  In addition, in the anhydrous urinal system, at least a part of the cartridge or the cover unit that can be visually recognized from the outside when attached to the anhydrous urinal body is coated or discolored or disappears by reaction with liquid or air. Preferably a layer is formed. And it is preferable that at least a part of the cartridge and the cover unit is made of a biodegradable material.

  In the above-described method for cleaning an anhydrous urinal system, the cleaning may be finally finished in a state where a cleaning liquid containing bacteria that consume ammonia is sprayed.

[Outline of the present invention]
FIG. 1 is a schematic configuration diagram of the entire urinal using the anhydrous urinal system of the present invention. This anhydrous urinal system is used for a male urinal that does not use washing water. As shown in the figure, at least a cartridge built-in portion 30 formed in the lower portion of the urinal body 20 is used. A replaceable cartridge 1 that is inserted and used, and a bacteria-derived cleaning agent 5 placed above the cartridge 1 are provided. The urinal body 20 is installed on, for example, the wall 40 and discharges the liquid (urine) that has passed through the cartridge 1 to the outside through the drain pipe 50.

  The cartridge 1 stores the liquid (urine) collected in the urinal body 20 tank to a predetermined water level, and discharges the liquid exceeding the predetermined water level to the drain pipe 50 side. The anhydrous urinal system has a function of blocking odor and a function of preventing adhesion of urine stones.

  Specifically (see, for example, FIG. 2 below), the cartridge 1 opens at least a trap (a liquid reservoir) 2 for storing a liquid to a predetermined water level, a lid 3 having an inlet 31, and an inlet 31. Opening / closing means 4 for closing is provided. The opening / closing means 4 may be, for example, a float configured to be able to close and open the inlet 31 using buoyancy F1 and gravity F2 received from the liquid 10 stored in the trap 2 (first and first). Embodiment 2). Moreover, the valve | bulb of the elastic membrane comprised so that the inflow port 31 could be closed and opened using an own elastic force may be sufficient (3rd Embodiment).

  The cleaning agent 5 is formed by solidifying bacteria extracted from the natural environment. When the liquid is poured, a part of the solid is melted and the dormant bacteria (spores) are activated. The bacteria of the cleaning agent 5 are ammonia self-consumption bacteria that, when activated, decompose urine to produce ammonia and also self-consume the produced ammonia. Thereby, undesired ammonia generated inside and outside the cartridge is consumed, and the odor from the urinal can be reduced. Moreover, the cleaning agent 5 may contain a fragrance | flavor. The cleaning agent 5 may be placed at any position above the cartridge 1 or above the lid 3. Further, if the cleaning agent 5 is placed on the lid as it is, it partially melts and collapses due to the contact state of urine, and the consumption of bacteria becomes violent, so it is stored in the cover unit 6 installed on the lid. It is preferable.

  Furthermore, the anhydrous urinal system of the present invention is preferably cleaned regularly or irregularly in order to prevent the generation of malodor and remove dirt. Here, in cleaning, it is preferable to use a liquid (cleaning liquid) containing ammonia self-consuming bacteria similar to the cleaning agent 5. In particular, the method for cleaning an anhydrous urinal system according to the present invention is preferably carried out without using water as much as possible because bacteria are washed away together with washing with water. For example, in the case of normal urinal cleaning, spray a cleaning solution containing ammonia self-consuming bacteria on the urinal body, wipe off dirt with a dry cloth or paper, and finally, the urinal body The cleaning is finished while the cleaning liquid is sprayed again. According to such a cleaning method, as compared with rinsing with water, since the dirt is simply wiped off with cloth or paper, the amount of water used can be suppressed. Furthermore, the ammonia self-consuming bacteria in the cleaning solution sprayed last accelerates the decomposition of urine during subsequent use. The timing of cleaning is appropriately set according to the use frequency and use state, but it is preferable to perform cleaning once or more a day. Note that the inside of the urinal may be washed away with water when the cartridge is exchanged or during a major maintenance such as cleaning the inside of the drain pipe. Embodiments of the present invention will be described below with reference to the drawings. However, the present invention is not limited to the following examples.

[Embodiment 1]
FIG. 2 is a schematic configuration diagram of the anhydrous urinal system according to the first embodiment of the present invention. The cartridge 1 of this embodiment employs a sedimentation type float as the opening / closing means 4. This figure shows a state when the user is not using the anhydrous toilet (hereinafter referred to as “when not in use”).

  The cartridge 1 includes a trap 2, a lid 3 and an opening / closing means 4. The trap 2 has an outlet 22 and stores the liquid 10 to a predetermined water level defined by the position of the outlet 22. The liquid exceeding the predetermined water level is discharged to the cartridge built-in portion 30 and the drain pipe 50 side through the outlet port 22. The trap 2 is made of hard plastic, earthenware, ceramics or the like. In particular, in the case of a replaceable type, the trap 2 is preferably made of an inexpensive and easy-to-manufacture plastic, more preferably a biodegradable plastic. It is preferable that In addition, it is good also as a system which replace | exchanges only the lid | cover 3 or the opening / closing means 4 without replacing | exchanging trap 2 itself.

  The lid 3 is a member that covers the upper portion of the trap 2, has an inlet 31 for flowing the liquid collected in the tank of the urinal body 20 into the trap 2, and holds the entire cartridge 1 in the built-in portion 30. The lid 3 is preferably configured to be inclined downward toward the central inflow port. In addition, the lid 3 in the figure is formed of an elastic resin as a separate body from the trap 2 and is configured to be fitted into the trap 2, but is not limited thereto. For example, the lid 3 may be made of hard plastic integrally with the body portion of the trap 2 or may be formed of hard plastic that is separate from the trap 2 and screwed into the groove of the trap 2 or the like. It may be a screw-in type that is screwed into a groove or the like provided in the built-in portion 30 instead of the trap 2. For at least a part of the lid 3 (for example, the outer peripheral portion that contacts the wall of the built-in portion 30 and the peripheral portion of the inflow port that contacts the opening / closing means 4), an adhesive member (rubber cap, O-ring, etc.) It is preferable that it is provided or made of an adhesive material (elastic resin). Moreover, you may comprise the whole lid | cover 3 with the material which has adhesiveness. As a result, it is possible to eliminate the gap and block the odor transmitted from the drain pipe 50 side. The lid 3 may have a guide wall 24 that stabilizes the floating and sinking operations of the float 4.

  The guide wall 24 is preferably formed in a cylindrical shape so as to extend below the water level of the liquid stored in the trap 2. Thus, the guide wall 24 also functions as a partition wall that blocks odor transmitted from the drain pipe 50 side. In the figure, the guide wall 24 is provided integrally with the lid 3, but may be provided integrally with the trap 2. Moreover, you may provide the guide wall 24 and the partition for an odor shielding separately.

  The float 4 has a head for closing the inflow port and a trunk extending downward from the head. The head of the float 4 is configured to be slightly larger than the inflow port, and the inflow port can be closed by contacting the peripheral edge of the head of the float 4 with the inflow port. The body of the float 4 is configured to reach the liquid 10 stored in the trap 2, and part of the body of the float 4 sinks into the liquid to obtain buoyancy.

  In the case of this embodiment, the float 4 pushes up the inflow port of the lid from below by the buoyancy of the float 4 and closes it. When the peripheral edge of the head of the float 4 is in contact with the inlet, the buoyancy that the float 4 receives from the liquid 10 in the trap 2 is F1, and the gravity due to the mass of the float 4 is F2. It is preferable to set and arrange the float 4 so that the difference ΔF (= F1−F2) is in the range of 0 to 1.00N, more preferably in the range of 0 to 0.50N.

  Here, the vertically upward direction (the direction of buoyancy) is positive. The buoyancy F1 corresponds to the weight of liquid equal to the volume under the waterline of the float 4 when not in use. In this embodiment, when the urinal is not used, F2 and F1 are the same or F1 is larger than F2. When F2 and F1 are equal (ΔF = 0), the float 4 is set and arranged so that the peripheral edge of the head of the float 4 and the inflow port are just in contact with each other. When F1 is larger than F2 (ΔF> 0), ΔF acts as a force for lifting the float 4 and pushes up the float 4 to close the inlet 31 of the lid 3 from below. The head of the float 4 may be made of a member having a sealing property (for example, rubber). The inside of the float 4 may be hollow, or may be configured with a member having a specific gravity smaller than that of the liquid. Further, in order to adjust the mass of the float 4 itself or to ensure stability, a ballast may be stacked inside.

  A cleaning agent 5 is placed on the top of the cartridge 1 (lid 3). The cleaning agent 5 is a solid substance derived from bacteria, and suppresses the generation of odor and adhesion of urinary stones in the body 20 of the anhydrous urinal, the built-in portion 30, the inside of the cartridge 1 and the drain pipe 50 through the activity of microorganisms. To do. When the user uses the anhydrous urinal (hereinafter referred to as “in use”), the cleaning agent 5 is partially melted by the liquid poured from above, and the dormant bacteria (spores) are activated, and the urinal It flows into the trap 2, the wall surface of the built-in portion 30, and the drain pipe 50 through the main body 20 and further through the inflow port 31. This bacterium decomposes urine to produce ammonia, and is an ammonia self-consuming bacterium that consumes ammonia produced in each part, and greatly reduces the generation of ammonia. For this reason, the possibility that the drain pipe 50 and the like are blocked by urine stones is reduced, and the cost required for maintenance management of the anhydrous urinal can be greatly reduced. Furthermore, the number of bacteria activated from the cleaning agent 5 exceeds the number of other bacteria (miscellaneous bacteria) that decompose the attached dirt and cause a bad odor. Therefore, there are various kinds of bacteria potentially present in anhydrous urinals. It may be possible to eliminate harmful effects of bacteria. Therefore, according to the present cartridge, it is possible to further suppress the odor of the anhydrous urinal and keep it in a sanitary state.

  Further, when the cleaning agent 5 is placed on the lid 3 as it is and the liquid directly hits it during use, the cleaning agent 5 is partially melted due to the contact condition of the liquid and the cleaning agent 5 collapses, and the contact area with the liquid Will increase the consumption of bacteria. Moreover, since the broken cleaning agent 5 entered the eyes of the user, it did not look good. For this reason, it is preferable that the cleaning agent 5 is stored in the cover unit 6 installed on the lid.

  The cover unit 6 is detachably provided on the lid 3 and includes a tray 61 and a cover 62. The receiving tray 61 has a recess 63 on which the cleaning agent 5 is placed and a plurality of holes 64 through which liquid pouring from above passes. The cover 62 has several micro holes 65 through which liquid that pours from above passes, and covers at least the cleaning agent 5 placed in the recess 63. When the anhydrous urinal system is used due to the micropores 65, since the liquid hits the cleaning agent 5 stored therein little by little, the cleaning agent 5 is melted by an appropriate amount for each use. For this reason, in this cartridge, the cleaning agent can be made to last longer than when the cover unit is not provided. Although it depends on the frequency of use and the state of use, it can also last about 3 to 10 times longer than the state without the cover unit. Furthermore, even if the cleaning agent 5 collapses, it can be hidden from the user's eyes by the cover 62. The cover unit 6 is preferably installed on the lid 3 via a plurality of legs (not shown), for example, and a gap 66 is preferably provided between the lid 3 and the cover unit 6. As a result, it is possible to pour body hair or a small piece of garbage that has fallen away from the user during use into the trap 2 together with the liquid, and there is little risk of impairing the aesthetic appearance.

  FIG. 3 shows a state when the anhydrous urinal system shown in FIG. 2 is used. When the anhydrous urinal system is used, most of the liquid discharged from the user is collected along the wall surface of the tank of the urinal body 20, but there is also a case where the liquid drips directly above the cartridge 1. As shown in the figure, when the liquid 13 is poured from above, a part of the liquid 13 passes through the micro holes 65 provided in the cover 62 of the cover unit 6 and hits the cleaning agent 5, and the other part is the cover. It passes through a hole 64 provided in the tray 61 of the unit 6. In this case, a part of the cleaning agent 5 is melted, and the activated bacteria are diffused together with the liquid.

  The liquid collected along the tank of the urinal body 20 and the liquid that has passed through the cover unit 6 travel toward the inlet 31 along the inclination of the lid 3. Initially, the inflow port 31 is closed by the float 4, so that the liquid is blocked on the upper surface of the lid 3. For this reason, the gravity F3 due to the mass of the liquid 15 that has been dammed adds the gravity due to the mass of the float 4 to F2. When the gravity F3 due to the mass of the dammed liquid 15 becomes larger than the force ΔF pushing up the float 4, the float 4 is guided by the guide wall 24 and starts to sink, but the float 4 sinks. Since the draft line of the float 4 goes up, the buoyancy F1 increases. For this reason, the behavior of the float 4 is determined by the balance between the gravity F2 + gravity F3 and the buoyancy F1 that changes as the float sinks. In this respect, since the amount of increase due to the sedimentation of the buoyancy F1 depends on the volume of the float 4, the behavior of the float can be controlled by appropriately designing the shape of the float 4. When the inlet 31 is opened due to the sedimentation of the float 4, the liquid 15 that has been blocked passes through the inlet 31 and flows into the trap 2. A portion of the liquid 10 stored in the trap 2 that exceeds a predetermined water level flows into the built-in portion 30 through the outlet 22 of the trap 2 and is finally discharged to the outside through the drain pipe 50. . When the liquid 15 that has been dammed is lost, the gravity F3 is lost, so the float 4 starts to rise again, and the inlet 31 is closed from below by the force of ΔF.

  In the above-described embodiment, an example in which the float that pushes up the inlet from below and closes the inlet is described as the opening / closing means, but a float that closes the inlet from above can also be used.

[Embodiment 2]
FIG. 4 is a schematic configuration diagram of an anhydrous urinal system according to the second embodiment of the present invention. In the cartridge 1 of this embodiment, a push-down float is employed as the opening / closing means 4. The figure shows the state when the anhydrous urinal system is used. Note that description of the cleaning agent and the cover unit is omitted.

  In the case of this embodiment, the float 4 closes by closing the inlet of the lid from above by gravity due to its own weight. The head of the float 4 is preferably made of a material that is hollow so that buoyancy can be obtained from the surrounding liquid, or a material having a specific gravity smaller than that of the liquid. When the buoyancy that the float 4 receives from the liquid 10 in the trap 2 is F1, and the gravity due to the mass of the float 4 is F2, the difference ΔF (F1-F2) between F1 and F2 is in the range of 0 to 1.00N, more preferably It is preferable to set and arrange the float 4 so as to be in the range of 0 to 0.50N.

  Here, the vertically downward direction (the direction of gravity) is positive. The buoyancy F1 corresponds to the mass of the liquid equal to the volume below the waterline of the float 4 when not in use. In the present embodiment, F1 and F2 are configured to be the same or larger than F1 when not in use. When F1 and F2 are equal (ΔF = 0), the float 4 is set and arranged so that the peripheral edge of the head of the float 4 and the inflow port are just in contact with each other. When F2 is larger than F1 (ΔF> 0), ΔF acts as a force for suppressing the float 4, and closes the float 4 by pushing down the inlet 31 of the lid 3 from above.

  As shown in the figure, the liquid 13 from above is directed to the inlet 31 that is closed along the inclination of the lid 3, but since the inlet 31 is initially closed by the float 4, the liquid is It is dammed on the upper surface of the lid 3. Then, when the head of the float 4 receives an additional buoyancy F4 from the liquid 15 that has been dammed up and becomes larger than the force ΔF that pushes down the float 4, the float 4 starts to rise, and the inlet 31 Open. When the dammed liquid 15 begins to flow out of the inlet 31 and starts to decrease, the float 4 loses the buoyancy F4 and starts to descend again, and the inlet 31 is closed from above by the force of ΔF.

  By the way, the float shown in FIG. 2, FIG. 3 or FIG. 4 closes the inlet 31 of the lid 3 by pushing it up or down depending on the difference between the buoyancy received from the liquid under the water line and the gravity due to its own weight. In order to efficiently flow the liquid dammed on the lid to the trap side, the liquid is displaced as much as possible following the external force (for example, F3 or F4) (that is, the inlet is greatly opened). Is preferred. Therefore, in one aspect of the present invention, the float may be provided with a buoyancy adjusting means capable of reducing a change in buoyancy during the rising or sinking operation. The buoyancy adjusting means may be realized, for example, by forming a part of the body of the float into a constricted shape.

  FIG. 5 is an explanatory view showing an example of float buoyancy adjusting means. In the case of a sink type float, for example, d1 is a draft when not in use (lowest draft), d2 is a draft when using (highest draft), and at least a part of the range of d1 to d2 of the float is trunked. You may form so that it may become smaller than the maximum diameter of a part. As a result, the float 4 can largely sink even with a slight external force.

  Moreover, the shape of the trunk | drum of a float may be suitably set as needed, and you may set arbitrarily the change of the buoyancy when a float sinks or floats. (A) of the figure is an example which comprised so that it might dent gently toward the average draft dm. FIG. 5B is an example of a body portion configured so that two conical columns are aligned at the apex with the average draft dm as the center. FIG. 3C is an example of a body portion constituted by a thin cylinder having a diameter smaller than the maximum diameter. The displacement amount of the float shown in FIGS.

  By the way, in the case of a sedimentation type float (see FIG. 3), when the gravity F3 due to the liquid dammed up on the lid becomes larger than the force ΔF pushing up the float, the float begins to sink, the inlet is opened, and the damming When the liquid that has been discharged is exhausted, the inlet is closed again. On the contrary, in the case of a floating type float (see FIG. 4), when the buoyancy F4 due to the liquid dammed on the lid becomes larger than the force ΔF pushing down the float, the float starts to float, the inlet is opened, and the dam When the stopped liquid is exhausted, the inlet is closed again.

  Strictly speaking, however, if the float pushing force (or pushing force) ΔF is set to be large to some extent, the inlet is closed before all the liquid dammed up on the lid flows downward, and a small amount of liquid is covered by the lid. May remain on top. In this case, not only the aesthetic appearance is impaired, but the liquid remaining on the lid may cause odor and dirt, which is not preferable for hygiene. Accordingly, it is preferable that the floated (or floated) float gradually floats (or settles) and returns to the closed position with a time difference. Therefore, in one aspect of the present invention, a braking unit that brakes the ascent operation may be provided in the sinking float, and a braking unit that brakes the sinking operation may be provided in the floating float.

  FIG. 6 is an explanatory view showing an example of a brake braking means. FIGS. 3A to 3D show an example in which a floating braking means is provided on a sinking type float body. In FIG. 2A, the float 4 is provided with a small tray 41 below the float head. The small tray 41 has a minute outlet 42. When the float settles, the liquid flowing down along the float head is temporarily held in the small tray 41. Since the mass of the float itself is increased by the small amount of liquid retained, the force ΔF that pushes up the float by this increase is reduced. A small amount of the retained liquid begins to be discharged through the minute discharge port 42 after all of the liquid blocked in the upper part of the inflow port disappears (that is, after the force of F3 disappears), and the retained liquid ΔF gradually increases as the value decreases. For this reason, when the levitation braking means is provided, the floating operation of the float is delayed, and the time until the inflow port is closed becomes longer (a time difference occurs). Therefore, there is little risk that a small amount of liquid will remain on the lid.

  In FIG. 5B, a recess 43 that is recessed toward the center is provided below the uppermost water line (when in use) of the sinking float body, and a minute discharge port 44 is provided. When the float settles, the recess 43 is filled with liquid, but when the force of F3 disappears, the liquid filled here begins to be discharged through the minute discharge port 44, as shown in FIG. As with, the force ΔF that pushes up the float gradually recovers. Moreover, in the same figure (C), the hollow 45 which is dented toward the periphery is provided below the uppermost water line (at the time of use) of a float trunk | drum, and the minute discharge port 46 is provided. When the float settles, the recess 45 is filled with liquid. When the force of F3 disappears, the liquid filled therein begins to be discharged through the minute discharge port 46, and FIGS. ), The force ΔF pushing up the float gradually recovers.

  On the other hand, FIG. 6D is an example in which a sedimentation braking means is provided on a floating float. In FIG. 4D, a recess 47 that is recessed toward the periphery is provided above the lowermost draft line (in use) of the body of the floating float, and a minute inlet 48 is provided. When the float floats, the depression 45 is empty, but when the force of F4 disappears, the float begins to sink due to the force ΔF that pushes down the float, and the liquid gradually fills the depression 47 through the inlet 48, The force ΔF that pushes down the float gradually increases. For this reason, when the sedimentation braking means is provided, the float sedimentation operation becomes slow, and the time until the inflow port is closed becomes long (a time difference occurs). Therefore, there is little risk that a small amount of liquid will remain on the lid.

  The configuration of the cartridge shown in each of the above embodiments is an example, and the shape and structure thereof can be variously modified. For example, as illustrated in Patent Document 1, the float is configured in a spherical shape, an elliptical shape, a cylindrical shape, a conical shape, a truncated cone shape, a pear shape, a U-shaped rotating body, and a combination thereof. Can do. An airfoil rib may be spirally provided on a part of the side surface of the float. As a result, the float rotates due to the pressure received from the ribs when it sinks or floats, generating a water flow in the trap and rubbing the edge of the inlet. For this reason, it can prevent that a dirt adheres to a contact part with an inflow mouth. Moreover, about a trap, it is good also as a 2 tank structure of the outer cylinder chamber connected to the float chamber which stores a float, and a drain pipe, for example. Further, the shape of the lid, the shape of the inlet provided in the lid, the arrangement of the outlets, and the like may be set as appropriate.

  As described above, according to the first and second embodiments, it is possible to provide an anhydrous urinal system that blocks odors by a physical mechanism without using electricity and chemicals. Since it is not necessary to wash with water every use, water resources can be saved greatly. In addition, in the case of other types of anhydrous urinals, maintenance such as replenishment of the sealing material in the cartridge is required. There is no need to replenish materials. In particular, if the cartridge is replaceable, the labor required for system maintenance can be reduced, and a cleaner environment can be maintained.

  In addition, by using a detergent derived from bacteria together, it is possible to reduce the odor generated from the anhydrous urinal and to suppress the accumulation of uric stones in the anhydrous urinal and the drain pipe. For this reason, the cost required for cleaning and maintenance can be greatly reduced as compared with conventional flushing or anhydrous toilets. When the cleaning agent is stored in the cover unit, the cleaning agent is melted by an appropriate amount every time it is used, so that the cleaning agent can be used for a long time.

  If the buoyancy adjusting means is used, the inlet of the cartridge can be greatly opened, and the liquid dammed on the lid can be efficiently discharged. By using the braking means for the floating or sinking operation, there is little possibility that a small amount of liquid remains on the lid, and the anhydrous urinal can be kept hygienic. Since this braking means is realized by a physical mechanism, it does not require electricity and simplifies the structure as compared with a sedimentation device that uses an electromagnet as exemplified in Patent Document 1 to settle the float. be able to.

[Embodiment 3]
FIG. 7 is a schematic configuration diagram of a cartridge according to the third embodiment of the present invention. In the cartridge 1 of the present embodiment, an elastic membrane valve is employed as the opening / closing means 4. The figure shows the state when the anhydrous urinal system is used. Note that description of the cleaning agent and the cover unit is omitted.

  The elastic membrane 4 is a member made of, for example, rubber and is closed by pushing up the inlet 31 of the lid 3 with its elastic force F1. When the liquid 13 is poured from above, the liquid 15 is dammed on the lid 3, and the gravity F2 by the liquid 15 exceeds the elastic force F1 of the valve, the valve is opened. When the dammed liquid 15 is gone, the valve closes the inlet 31 again. The elastic force of the elastic membrane valve is preferably set in the range of 0 to 1.00N, more preferably in the range of 0 to 0.50N. Moreover, in the same figure, although the elastic film is provided in the lid | cover 3 so that the one side may be supported, it is not limited to this. The periphery of the film may be provided in a part of the lid, and a part of the film may be lowered along the cut. Moreover, although the film | membrane which has elastic force was described as the opening-and-closing means 4 in the figure, it is not limited to this. For example, a closing flat plate and a spring may be used.

  In the same figure, it is not necessary to provide a guide wall for guiding the floating and sinking operations of the float, but it is preferable to dispose the partition wall 24 extending from the trap 2 or the lid 3 to block the odor transmitted from the drain pipe 50.

  As described above, according to the third embodiment, since the opening / closing means is not directly immersed in the liquid in the trap, the opening / closing means itself becomes dirty unlike the case of using the floats of the first and second embodiments. There is little possibility of adhesion. Therefore, there is little possibility that the mass of the opening / closing means itself changes due to dirt or the like and the force for closing the inflow port changes.

  And in this invention, you may provide the parameter | index which shows the replacement time of the cartridge 1 in said Embodiment 1-3. As an index indicating the replacement time, an area visible to the user of the anhydrous urinal system, for example, a coating that discolors or disappears due to reaction with liquid or air on the lid 3 of the cartridge 1 and a part of the opening / closing means 4 You may give it. As a result, the color of such a coating changes with each use, or the layer of such a coating gradually melts and disappears, so that after a predetermined number of uses or after a predetermined period of time, the user Can know when to replace the cartridge.

  In addition, it is preferable that all or part of the cartridge 1 (which may include the cover unit 6) is made of a biodegradable material (for example, plastic derived from biomass). Thereby, even if it is difficult to incinerate the used cartridge after replacement, it can be easily processed by reducing the used cartridge to soil or the like.

  About the anhydrous urinal system of this invention, after using it for three months from installation, the diagnosis in the urinal drain pipe by the endoscope and the odor density diagnosis by the ammonia detector pipe were performed. When the cartridge was removed, the endoscope was inserted into the pipe, and the inside of the urinal drain tube was observed, a slight yellow stain was present, but it was not fixed and was a soft stain that fell off when rubbed. Furthermore, when the ammonia concentration in the cartridge assembly part of the urinal body after removing the cartridge and in the trap of the cartridge was measured with an ammonia detector tube, the ammonia concentration was 0 ppm. In addition, the smell of ammonia was not detected in the toilet room.

  As described above, in the case of the anhydrous urinal system using the cartridge and the cleaning agent of this example, the generation of ammonia could be suppressed to 0 ppm with the optimum setting. In addition, about 100 ppm of ammonia was generated even in a normal flush toilet, and in other anhydrous urinals, an ammonia concentration of 800 ppm was sometimes measured. As described above, the anhydrous urinal system of the present embodiment, as a whole, greatly suppresses the generation of ammonia by using a cleaning agent that employs cartridges and ammonia self-consuming bacteria. Is made possible.
