Description

  In the present invention, the wash water that has flowed down the toilet surface of the male water urinal is allowed to flow from the toilet drain to the circulation washing water tank, and the washing water in the circulation washing water tank is circulated to the small water toilet for repeated reuse. , It relates to the circulation flush toilet for men.

  Commercial toilets in large-scale commercial facilities, transportation stations, airports, motorway parking areas, schools, factories, buildings, etc. have many toilet bowls and are frequently used. Simplification of cleaning work and improvement of hygiene are important issues. However, in recent men's flush toilets, consumption of washing water has been reduced to enable significant water savings, and drug components added to washing water for the purposes of sterilization, deodorization, antifouling, etc. are effective. In order to reduce the waste that is discarded while leaving the water, a circulation type that automatically collects the used cleaning water and can be reused repeatedly is spreading.

  This circulatory flush toilet for men can generally be switched between a drainage pipe connecting the drainage channel to the sewer and a circulating washing tank by means of a switching valve provided below the toilet drain of the small water toilet. The presence of the user is detected by human body detection means such as an optical sensor, and the user's small water is guided to the drain pipe. The washed water is made to flow into the circulating washing water tank and collected, and the washing water in the circulating washing water tank is circulated to the small water toilet and reused repeatedly (for example, Patent Document 1). In addition, in such a men's circulation flush toilet, in order to enhance the cleaning effect, a small amount of cleaning water is poured as the initial cleaning at the stage where the presence of the user is detected or immediately after the user leaves, and the cleaning water is discharged. A two-stage cleaning method is also employed in which a relatively large amount of cleaning water is allowed to flow as the main cleaning after being discharged to the drain pipe together with the small water, and the cleaning water for the main cleaning is guided to the circulating cleaning water tank and collected.

Japanese Patent No. 3853825

  However, in the conventional men's circulating flush toilet, most of the foreign matter mainly consisting of body hair (pubic hair) falling on the toilet bowl is discharged to the drainage pipe side with small water or initial wash water, Since it is inevitable that a part of it flows into the circulating cleaning water tank along with the recovered cleaning water, the amount of foreign matter in the circulating cleaning water tank will increase with time, and the foreign matter in this circulating cleaning water tank will become the cleaning water. Moving together to the circulation path causes various troubles. In particular, pumps for circulation and discharge of washing water are weak against fibrous foreign matters such as body hair, and foreign matters are entangled with rotating parts such as blades, and malfunctions and operation stops are likely to occur. In addition, clogging due to foreign matters is likely to occur even in the cleaning nozzle that discharges cleaning water to the toilet bowl and the piping in the circulation path. Furthermore, if the amount of cleaning water in the circulating cleaning water tank decreases to a certain extent, it is normal to detect this and automatically supply new cleaning water from the water pipe and chemical liquid from the chemical tank. When the operation is performed by a float switch provided in the circulating cleaning water tank, if the amount of foreign matter in the circulating cleaning water tank increases, the lifting / lowering operation of the float switch is hindered, the water level is not detected, and the amount of cleaning water falls short. Also often.

  In view of the above-mentioned circumstances, the present invention reliably prevents foreign substances such as body hair from flowing into the circulating cleaning water tank with the recovered cleaning water by using a very simple configuration as a male circulating flush toilet. Accordingly, it is an object of the present invention to provide a device that can prevent various troubles caused by the foreign matter and can easily remove the foreign matter.

  If the means for achieving the above object is shown with reference numerals in the drawings, the invention of claim 1 is that a circulating washing water tank 2 is installed on the inner bottom of the toilet main body 1 of a male water urinal. The wash water W that has flowed down 10 flows into the circulating wash water tank 2 from the toilet drain 11 and is collected, and the wash water W in the circulating wash water tank 2 is circulated to the small water toilet and reused repeatedly. The male-use circulation flush toilet for men is characterized in that a porous strainer 3 is detachably disposed in an inflow portion 21 of the recovered washing water W in the circulation washing water tank 2.

  The invention according to claim 2 is the men's circulating flush toilet according to claim 1, wherein the strainer 3 has a perforated edge 32 standing on the periphery of the perforated flat plate portion 31 covering the upper open portion 20 of the circulating wash water tank 2. It is characterized by having an overflow gap t between the perforated edge portion 32 and the inner peripheral surface of the circulating cleaning water tank 2 with the strainer 3 disposed in the circulating cleaning water tank 2. .

  According to a third aspect of the present invention, in the circulation flush toilet for men according to the first or second aspect, the strainer 3 can be detachably attached to the circulation flush water tank 2 in a drawer manner.

  Next, if the effects of the present invention are shown with reference numerals in the drawings, the male flush toilet according to the first aspect of the present invention is arranged at the inflow portion 21 of the recovered wash water W in the circulation wash water tank 2. Since foreign substances such as body hair mixed in the recovered cleaning water W are scooped out by the porous strainer 3, only the recovered cleaning water W from which the foreign objects have been removed flows in and is stored in the circulating cleaning water tank 2. Therefore, while the straining ability of the strainer 3 is maintained, the foreign matter in the circulating cleaning water tank 2 is not mixed with the cleaning water W and moves to the circulation path. Operation of the float switch that controls the malfunction and operation stop caused by the foreign matter, clogging of foreign matter in the cleaning nozzle that discharges cleaning water to the toilet surface and the piping of the circulation path, and the supply of cleaning water and chemicals to the circulating cleaning water tank 2 Various troubles such as malfunction due to foreign matter are prevented in advance. In addition, since the strainer 3 can be attached to and detached from the circulating washing water tank 2, the strainer 3 is removed from the circulating washing water tank 2 after a predetermined usage time of the male circulating flush toilet, and the foreign matter that has been wiped off is removed. It can be easily dumped into a garbage bag or the like, and the strainer 3 after the dumping can be easily washed with water or the like, and can be remounted in the circulating washing water tank 2 in a clean state.

  According to the invention of claim 2, the strainer 3 has a tray-like shape in which the perforated edge 32 is raised and formed at the periphery of the perforated flat plate portion 31 covering the upper open portion 20 of the circulating washing water tank 2. Since the cleaning water W to be collected can be wiped off in the form of spreading on the porous flat plate portion 31 having a large area, a large amount of foreign matter can be captured before the entire porous flat plate portion 31 is clogged. Even if the entire portion 31 is clogged, a larger amount of foreign matter can be captured by scoring the perforated edge 32. In addition, since there is an overflow gap t between the perforated edge portion 32 of the strainer 3 and the inner peripheral surface of the circulating cleaning water tank 2, the entire strainer 3 may become clogged and become unusable. However, it is possible to overflow the recovered cleaning water W flowing in from the perforated edge 32 and flow down into the circulating cleaning water tank 2 from the overflow gap t, and the recovered cleaning water W is clogged with the strainer 3 to the periphery. The situation where the toilet body 1 is flooded and flooded is not reached.

  According to the invention of claim 3, since the strainer 3 can be detachably attached to the circulating cleaning water tank 2, the strainer 3 can be removed from the circulating cleaning water tank 2 very easily when the squeezed foreign matter is discarded. In addition, the strainer 3 after the disposal of foreign matter can be easily attached to the circulating cleaning water tank 2.

It is a longitudinal front view of the lower part of the circulation type flush toilet for men. It is a schematic diagram which shows the piping structure of the circulation type flush toilet for the men. It is a perspective view which shows the circulation washing water tank in the circulation washing toilet for men.

  Below, the circulation type flush toilet for men concerning one embodiment of the present invention is explained concretely with reference to drawings. The present invention is not limited to the configuration of the embodiment.

  As shown in FIG. 1 to FIG. 3, this male circulation flush toilet is a switching valve unit located on the inner bottom of a toilet body 1 constituting a toilet bowl surface 10 having a concave front side, directly below the toilet drain 11. 4, a circulation washing water tank 2 located on the left side, and a circulation pump P <b> 1 located on the right side. Further, a control device 6 and a chemical liquid tank 7 are arranged in the upper part inside the toilet body 1, and a sub tank 8 and a discharge pump P2 are arranged in the middle part thereof. And the human body detection means 12 which consists of an optical sensor etc. for detecting presence of a user is provided in the front top part of the toilet bowl main body 1, and the wash water W is discharged toward the toilet bowl surface above the toilet bowl surface 10. A cleaning nozzle 13 is attached. Reference numeral 14 denotes an eye plate placed on the toilet drain 11.

  The switching valve unit 4 switches the drainage channel from the toilet drain 11 to the drainage pipe 15 side connected to the sewer and the recovery channel 16 side to the circulating washing water tank 2, and is set by a program setting of the control device 6. The switching operation is automatically performed based on the detection of the user by the human body detection means 12. For example, in the two-stage cleaning method, a small amount of cleaning water W is discharged from the cleaning nozzle 13 as initial cleaning when the user stands in front of the toilet surface 10 or immediately after the user leaves after urination. Then, since the drainage flow path is connected to the drainage pipe 15 side in the switching valve unit 4, the cleaning water W and the small water U for the initial cleaning are discharged to the drainage pipe 15. Then, after a predetermined time (generally about 5 to 10 seconds) has passed since the user left, a relatively large amount of cleaning water W is flowed as the main cleaning. By switching to the 16 side, the cleaning water W for the main cleaning is guided to the circulating cleaning water tank 2 and collected.

  Although the switching valve unit 4 is illustrated as a flap valve that switches a flapper with a rotary actuator in the figure, a switching valve having various switching mechanisms such as a three-way valve, a rotary valve, and a solenoid valve can be employed.

  The washing water W stored in the circulation washing water tank 2 is sent to the sub tank 8 through the circulation flow paths L1 and L2 by the circulation pump P1, and further sent from the sub tank 8 to the washing nozzle 13 through the circulation flow path L3 by the discharge pump P2. It is done. A filter 17 for removing minute solid foreign matters is interposed in the circulation flow path L2 from the circulation pump P1 to the sub tank 8. The sub tank 8 is connected to a drain flow path L4 that hangs down from the bottom via the on-off valve V1 and an overflow flow path L5 that overflows excess cleaning water W. The cleaning water W is discharged into the circulating cleaning water tank 2. When the sub tank 8 is not installed, it is desirable to provide a check valve instead to prevent the cleaning water from flowing backward.

  As shown in detail in FIG. 4, the circulating cleaning water tank 2 has a narrow water receiving portion 2 b integrally formed on one end side of a substantially rectangular main body portion 2 a opened upward, and the water receiving portion 2 b. The outlet 16a of the recovery channel 16 opens in a rectangular shape on the upper side wall of the main body 2a, and the recovery washing water W flowing from the outlet 16a is allowed to flow onto the main body 2a by the frame plate 21a fitted to the upper part of the water receiving part 2b. An inflow passage 21 is formed to lead to. A strainer 3 made of a synthetic resin molding in the form of a tray is disposed on the upper part of the main body 2a, and the recovered cleaning water W from the inflow passage 21 is trapped by the strainer 3 and flows into the main body 2a. It is like that.

  The strainer 3 can be attached to and removed from the circulating washing water tank 2 in a drawing manner as shown by phantom lines in FIGS. 2 and 4, and a porous flat plate portion 31 that covers substantially the entire upper open portion 20 of the main body portion 2 a; It consists of a perforated projecting edge portion 32 raised from the periphery excluding one side of the drawer side and an edge frame portion 33 with a handle 33a provided on one side of the drawer side. The perforated protruding edge portion 32 and the edge frame portion 33 have the same vertical width, but the entire edge frame portion 33 is closed with respect to the inner side. On the other hand, the left-side wall 1a of the toilet body 1 is provided with an open / close door 18 having a vertical width that allows a human hand to be inserted and a width that is slightly wider than the strainer 3 at a height corresponding to the strainer 3. The open / close door 18 is opened so that the strainer 3 can be attached and detached.

  A slit-like opening 22 for allowing the strainer 3 to enter and exit is provided on the side wall of the main body 2a of the circulating washing water tank 2, and a packing 23 is fitted on the inner periphery thereof as shown in FIG. The packing 23 prevents the cleaning water W from leaking from the slit-like opening 22 in the mounted state. Further, a pair of support bars 24 (see FIG. 1) are installed in the circulating cleaning water tank 2 between the side of the slit-shaped opening 22 and the opposite side wall, and the strainer 3 inserted from the slit-shaped opening 22 is installed. It is designed to be supported on both the left and right sides. In addition, when the strainer 3 is mounted, an overflow gap t is provided between the perforated edge 32 and the inner peripheral surface of the circulating washing water tank 2.

  Furthermore, a drain flow path L6 connected from the bottom to the drain pipe 15 via the on-off valve V2 is connected to the circulating cleaning water tank 2. On the other hand, above the circulating washing water tank 2, an outlet of a water supply path L7 for supplying new washing water W from a water pipe (not shown) via an opening / closing valve V3, and an opening / closing valve V4 for supplying a chemical solution from the chemical tank 7. And an outlet of a chemical liquid supply path L8 to be supplied via the line. A float switch 9 is provided in the circulating cleaning water tank 2, and when the stored cleaning water W is lowered to a set value that requires replenishment, the float switch 9 detects it from the liquid level. The on-off valves V3 and V4 of the water supply path L7 and the chemical liquid supply path L8 are opened.

  In the male circulation flush toilet with the above configuration, for example, when the two-stage washing method is set, the drainage flow path from the toilet drainage port 11 is connected to the drainage pipe 15 side in the standby state, and the user can When standing in front of the surface 10, the human body detecting means 12 detects it, and at that time or immediately after the user leaves after urination, a small amount (for example, about 150 ml) of cleaning water W is discharged from the cleaning nozzle 13 as initial cleaning. Then, the cleaning water W and the small water U of the initial cleaning are discharged to the drain pipe 15. Then, after a certain time (for example, 8 seconds) after the user leaves, the switching valve unit 4 switches the drainage channel to the recovery channel 16 side, and a relatively large amount (for example, 1000 ml) from the cleaning nozzle 13 as the main cleaning. The cleaning water W of this main cleaning is led from the recovery channel 16 to the circulating cleaning water tank 2, and the recovered cleaning water W flowing out from the outlet 16a of the recovery channel 16 is the strainer. By passing 3, foreign matter such as body hair mixed in is scooped out and flows into and stored in the circulating washing water tank 2 in a clean state from which the foreign matter has been removed.

  Accordingly, while the straining ability of the strainer 3 is maintained, the foreign matter in the circulating cleaning water tank 2 is not mixed with the cleaning water W and moves to the circulating flow paths L1 to L3, and the circulation pump P1 and the discharge pump P2 Foreign matter of the float switch 9 that controls malfunction or operation stop caused by the foreign matter, clogging of foreign matter in the piping of the cleaning nozzle 13 or the circulation flow paths L1 to L3, and supply of the cleaning water W and the chemical solution to the circulating cleaning water tank 2 Various troubles such as malfunction due to can be prevented in advance.

  Thus, in the strainer 3 of the embodiment, since the porous protruding portion 32 is raised and formed on the periphery of the porous flat plate portion 31 covering the upper open portion 20 of the circulating cleaning water tank 2, the inflowing recovery is performed. Since the cleaning water W can be wiped out in the form of spreading on the porous plate portion 31 having a large area, a large amount of foreign matter can be captured before the entire porous plate portion 31 is clogged, and the porous plate portion can be captured. Even if the entire 31 is clogged, a larger amount of foreign matter can be captured by wiping at the perforated edge 32. Moreover, in the configuration of the embodiment, since the overflow gap t is provided between the perforated edge portion 32 of the strainer 3 and the inner peripheral surface of the circulating cleaning water tank 2, the entire strainer 3 is temporarily clogged and removed. Even if it becomes impossible, the recovered cleaning water W that flows in can overflow from the perforated edge 32 and flow down into the circulating cleaning water tank 2 from the overflow gap t. The clogging of 3 does not cause a situation where the toilet body 1 is flooded and flooded in the vicinity.

  Further, since the strainer 3 can be detachably attached to the circulation washing water tank 2, the strainer 3 is pulled to the side from the circulation washing water tank 2 after a predetermined usage time of the men's circulation washing toilet. In addition to being able to be removed very easily in the form of taking out, the foreign matter scraped from the removed strainer 3 can be easily dumped into a garbage bag, etc., and the strainer 3 after dumping can be easily washed with water, etc. It can be easily remounted in the circulating cleaning water tank 2 in a clean state.

  In the embodiment, the cleaning water W in the circulating cleaning water tank 2 is sent to the sub tank 8 by the circulation pump P1, and sent from the sub tank 8 to the cleaning nozzle 13 by the discharge pump P2. Then, it is good also as a structure directly sent to the washing | cleaning nozzle 13 with the circulation pump P1, not via the sub tank 8 and the discharge pump P2. Further, in the present invention, the shape of the circulating cleaning water tank 2 and the strainer 3, the mounting structure of the strainer 3 to the circulating cleaning water tank 2, the branching structure from the toilet drain port 11 to the drain pipe 15 and the recovery flow path 16, the toilet body 1 Various design changes other than the embodiment can be made for the detailed configuration such as the shape and the arrangement configuration of each component member and piping in the toilet body 1.
