Description

  The present invention relates to a male flush toilet used exclusively for men's small water.

  In men's flush toilets, in order to keep the toilet surface clean, the user's push button operation after urination, automatic operation by human body detection means such as optical sensors, automatic operation at regular intervals by timer setting, etc. The washing water is made to flow down from the washing nozzle provided on the top of the nozzle. However, in the conventional flush toilet for men, the eye plate is generally fitted in the drain outlet at the bottom of the toilet bowl, and small water and wash water are formed between the periphery of the eye dish and the toilet bowl. From the flow gap or the flow gap provided in the flow tray and the eye plate itself, but the inflow portion is generally narrow, so that the user's body hair (pubic hair), eyelids, cigarette butts, Often, clogging with foreign substances such as urine stones occurs, and the clogging makes it impossible to drain the water, and the toilet is spilled with sewage.

  In addition, as a men's flush toilet in recent years, the 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 of being left and discarded, a circulation type that automatically collects the used cleaning water and repeatedly reuses it is becoming widespread. In this circulation type flush toilet for men, the presence of the user is detected by the human body detection means, and the user's small water is guided to the drain pipe, while the drainage flow path is circulated by the switching valve after the user leaves. The washing water that has flowed down the toilet surface flows into the circulating washing water tank and is collected, and the collected washing water is supplied to the washing nozzle via the circulation pump and the discharge pump (for example, Patent Document 1). However, in the case of such a male circulating flush toilet, the foreign matter mixed in the cleaning water is liable to cause clogging of piping in the cleaning water circulation path, malfunction of pumps, and the like.

  As a means of suppressing clogging of drainage in flush toilets for men, it is possible to simply widen the flow gap around the periphery of the eye plate to make it easier for foreign objects to flow into the drainage port. There is a concern that a serious situation may be caused by clogging of foreign matter in the drainpipe, and troubles in the washing water circulation section frequently occur due to an increase in the amount of foreign matter mixed in the wash water, particularly in the circulation toilet. Therefore, it is desirable to collect the foreign matter in the toilet in some form and remove it during cleaning. For example, even if a strainer is fitted in the drain instead of the eye plate, the flush toilet for men is used frequently. Then, in a short time, the strainer becomes clogged and it becomes impossible to drain.

  In view of the above-mentioned circumstances, the present invention can prevent clogging of drainage over a long period of time while collecting foreign substances such as body hair, scissors, butts and urine stones as a men's flush toilet. It aims at providing what can be easily taken out and removed during cleaning.

And an inflow / outflow gap g1 between the outer peripheral edge of the developing part 22 of the strainer 2 and the outer peripheral edge of the eye plate 3, and the lower surface side of the developing part 22 of the strainer 2 and the bottom of the toilet bowl surface 10 Between the outer peripheral surface of the concave portion 21 of the strainer 2 and the inner peripheral surface of the drain port 11, and an overflow gap between the outer peripheral edge of the developing portion 22 and the toilet surface 10. It is characterized by having g4 respectively.

  According to a second aspect of the present invention, in the flush toilet for men according to the first aspect, the outer peripheral portion of the developing portion 22 of the strainer 2 forms a rising edge portion 22a.

  The invention according to claim 3 is the male flush toilet according to claim 1 or 2 described above, wherein the protrusions for securing the outflow gaps g2 and g3 on the outer peripheral side of the recessed portion 21 of the strainer 2 and the lower surface side of the developing portion 22 are provided. The parts 23 and 24 are formed.

  According to a fourth aspect of the present invention, in the flush toilet for men according to any one of the first to third aspects, an opening is provided at the center of the eye plate 3.

  A fifth aspect of the present invention is the male flush toilet according to any one of the first to fourth aspects, further comprising a washing water circulation mechanism S that collects the washing water W that has flowed down the toilet face 10 and reuses it for washing the toilet face. It becomes the composition which becomes.

  Next, if the effects of the present invention are shown with reference numerals in the drawings, in the flush toilet for men according to the invention of claim 1, the small water U and the flush water W that have flowed down the toilet surface 10 are provided by the strainer 2. By flowing into the strainer 2 from the inflow / outflow gap g1 between the outer peripheral edge of the developing portion 22 and the outer peripheral edge of the eye plate 3, foreign matter such as body hair, wrinkles, butts and urine stones mixed therein is removed. 2, only the liquid flows out of the strainer 2, flows down from the drainage port 11 through the outflow gaps g2 and g3, and is discharged. Thus, the strainer 2 has a large crease area due to the development part 22 projecting from the upper peripheral edge of the recessed part 21 fitted into the drain outlet 11 onto the bottom part of the toilet bowl 10, so that the entire strainer 2 is large in volume until it is clogged. In addition to trapping foreign matter, the small water U and the wash water W that flow in may overflow from the outflow / inflow gap g1 to the outer overflow gap g4 even if the whole becomes clogged and cannot be removed. It can be discharged from the mouth 11. Therefore, in this men's flush toilet, even when the frequency of use is high, clogging of drainage can be prevented for a long time, and it is only necessary to remove foreign matter accumulated in the strainer 2 at a rate of about once a day, for example. The removal operation can be easily performed by taking out the strainer 2 at the time of cleaning.

  According to the invention of claim 2, since the outer peripheral portion of the developing portion 22 of the strainer 2 forms a rising edge portion 22a, the amount of foreign matter captured by the strainer 2 is remarkably increased, thereby preventing clogging of drainage for a longer time. it can.

  According to the invention of claim 3, the strainer 2 has the convex portions 23 and 24 on the outer peripheral side of the concave portion 21 and the lower surface side of the developed portion 22, so that the concave portion 21 is simply fitted into the drain port 11. Outflow gaps g2 and g3 are secured.

  According to the invention of claim 4, since the opening 31 is provided in the center of the eye plate 3, a user often psychologically urinates toward the opening 31, thereby urine droplets outside the toilet. The rebound of less.

  According to the invention of claim 5, in the men's flush toilet provided with the washing water circulation mechanism S, a large amount of foreign matters can be efficiently captured by the strainer 2 fitted in the drain port 11, and therefore, the foreign matters are mixed in the washing water circulation section. Trouble is suppressed.

It is a general | schematic longitudinal side view of the flush toilet for men which concerns on one Embodiment of this invention. The strainer used for the flush toilet for men is shown, (a) is a top view, (b) is a front view, and (c) is a sectional view taken along line XX in (a). It is a vertical side view of the principal part which shows the strainer fitted to the drain outlet of the toilet bowl, and the separated eye plate. It is a schematic diagram which illustrates the flow-path structure of the washing water circulation mechanism of the flush toilet for men.

  Below, the men's flush toilet 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, the flush toilet for men is provided with a drain port 11 at the bottom of a concave toilet surface 10 formed on the front side of the toilet body 1, and the drain port 11 is made of a synthetic resin molding. A porous strainer 2 is fitted, and on the strainer 2, a pan 3 made of a synthetic resin molding is placed. And the human body detection means 5 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 flush water is discharged toward the toilet bowl surface 10 in the upper part of the toilet bowl surface 10. A cleaning nozzle 6 is attached, and a control device C that controls a cleaning water circulation mechanism, which will be described later, is installed on the inner upper portion of the toilet body 1. On the other hand, a channel branch pipe 7 is connected immediately below the drain port 11, and a drain pipe 12 with a trap 12 a connected to the sewer is connected to the lower side of the channel branch pipe 7. Further, a switching valve unit 4 for driving a valve body for switching the flow path disposed in the flow path branch pipe 7 is attached to the outside of the flow path branch pipe 7. Although omitted in FIG. 1, pipes, tanks, valves, pumps, and the like that constitute a washing water circulation mechanism are disposed inside the toilet body 1.

  As shown in FIGS. 2A to 2C, the strainer 2 has a high cup shape including a cylindrical recessed portion 21 and a circular developed portion 22 projecting outward from the upper peripheral edge thereof. In the center of the concave portion 21, a rod-like handle 25 is erected and the outer peripheral portion of the developing portion 22 is inclined obliquely outward. A raised edge 22a is formed. A plurality of (four in the figure) rib-like convex portions 23 extending in the vertical direction are formed on the outer peripheral surface of the concave portion 21 so as to be equally arranged in the circumferential direction. A plurality of small protrusion-like convex portions 24 are formed on the outer peripheral side of the lower surface of the lower surface of the lower surface of the lower surface.

  As shown in FIG. 3, the drain port 11 of the toilet body 1 is configured by a cylindrical drain adapter 13 fitted from above into a hole 10 a at the bottom of the toilet surface 10. The drainage adapter 13 is fixed to the hole 10a by screwing and tightening a nut 14 from below to a male screw part 13b provided on the outer periphery with the upper end flange part 13a engaged with the periphery of the hole 10a. . Further, the flow path branch pipe 7 is branched into a droop pipe 71 whose lower side is connected to the drain pipe 12 and a side pipe 72 that guides the recovered wash water to a wash water storage tank T1 (see FIG. 4) described later. The upper end flange portion 7a is hooked and supported on the support frame 15 provided in the toilet main body 1 in a state where the upper side cup-shaped inlet pipe portion 70 is externally fitted to the nut 14 from below. Although not shown, a seal ring is interposed between the upper end flange portion 13a of the drainage adapter 13 and the toilet surface 10, and between the inlet pipe portion 70 of the flow branch pipe 7 and the nut 14. Liquid-tightly sealed.

  Thus, in the strainer 2, the developed part 22 is supported on the toilet surface 10 via the convex part 24 by fitting the recessed part 21 into the drain port 11. In the fitted state of the strainer 2, an outflow gap g <b> 2 is ensured between the lower surface side of the developing part 22 and the bottom of the toilet surface 10 by the convex part 24 of the developing part 22, and the convex part 23 on the outer periphery of the concave part 21. Thus, an outflow gap g3 is secured between the outer peripheral surface of the recessed portion 21 and the inner peripheral surface of the drain port 11 (drainage adapter 13).

  In addition, the strainer 2 is disposed such that the cylindrical recess 21 is eccentric with respect to the circular development part 22 and the wide side of the development part 22 faces the back side of the toilet surface 10. In addition, a circular concave surface portion 10b corresponding to the strainer 2 is formed at the bottom of the toilet surface 10, and the outer peripheral edge of the developing portion 22 is the concave surface with the strainer 2 fitted into the concave surface portion 10b. The size is set so as to be approximately the same height as the upper peripheral edge of the portion 10 b and to form an overflow gap g 4 with the toilet surface 10.

  The eye plate 3 is formed in a substantially disk shape whose upper surface side forms a substantially convex spherical surface, has a circular opening 31 at the center thereof, and a plurality (four in the figure) of rod-shaped leg pieces 32 on the lower surface side. Are vertically arranged in the circumferential direction. Then, by placing the eye plate 3 on the development part 22 of the strainer 2 via the rod-shaped leg piece 32, an inflow / outflow gap g1 (FIG. 1) is formed between the outer peripheral edge and the outer peripheral edge of the development part 22 of the strainer 2. ) Is configured.

  Here, it is preferable that the outflow / inflow gap g1 is about 1 to 5 mm, the outflow gaps g2 and g3 are about 0.5 to 2 mm, and the overflow gap g4 is about 0.5 to 2 mm. Further, the water passage hole 20 of the strainer 2 is preferably about 0.5 to 2 mm in diameter. Further, the opening 31 of the eye plate 3 is preferably 20 to 50 mm in diameter.

  In the men's flush toilet having the above-described configuration, the small water U and the wash water W that have flowed down the toilet surface 10 are mainly on the strainer 2 from the inflow / outflow gap g1 between the outer peripheral edge of the strainer 2 and the outer peripheral edge of the eye plate 3. Foreign matter such as body hair, wrinkles, butts, urine stones, and the like that have been mixed in is drained by the strainer 2 and only the liquid flows out of the strainer 2 and flows out from the drainage port 11 through the outflow gaps g2 and g3. It flows down and is discharged. Thus, the strainer 2 has a wide scooping area due to the development part 22 projecting around the recessed part 21, and the outer peripheral part of the development part 22 forms a rising edge 22a, so that the whole is clogged. A large amount of foreign matter can be captured. Moreover, even if the entire strainer 2 becomes clogged and cannot be removed, the inflowing small water U and the washing water W are overflowed from the outer peripheral edge of the developing portion 22 to the overflow gap g4 to discharge the drain 11 It can discharge more.

  Therefore, in this men's flush toilet, even when the frequency of use is high, clogging of drainage can be prevented for a long time, and it is only necessary to remove foreign matter accumulated in the strainer 2 at a rate of about once a day, for example. The removal operation can be easily performed by taking out the strainer 2 at the time of cleaning. In addition, since a large amount of foreign matter can be efficiently captured by the strainer 2 fitted in the drain port 11 in this way, troubles caused by foreign matter mixing in the washing water circulation section are also suppressed as will be described later.

  In addition, since the user often psychologically urinates toward the opening portion 31 by having the opening portion 31 in the center of the eye plate 3, this reduces the rebound of the urine droplets outside the toilet. There is an advantage that wet dirt around the toilet bowl is reduced, leading to a reduction in cleaning effort.

  An example of the washing water circulation mechanism of this men's flush toilet is shown in FIG. In the washing water circulation mechanism S, the switching passage unit 4 directly below the drain port 11 can switch the drain passage between the drain pipe 12 side and the recovery passage L1 side to the washing water storage tank T1. The wash water W in the wash water storage tank T1 is sent to the upper sub tank T2 through the circulation flow path L2 by the circulation pump P1, and further sent from the sub tank T2 to the washing nozzle 6 through the circulation flow path L3 by the discharge pump P2. And is discharged from the washing nozzle 6 to the toilet surface 10.

  The sub-tank T2 is connected to a drain channel L4 that hangs down from the bottom via the on-off valve V1 and an overflow channel L5 that overflows excess cleaning water W. The cleaning water W is discharged into the cleaning water storage tank T1. In addition, a drain flow path L6 that is connected to the drain pipe 12 from the bottom thereof via the on-off valve V2 is connected to the wash water storage tank T1. Further, on the cleaning water storage tank T1, an outlet of a water supply path L7 for supplying new cleaning water W from a water pipe (not shown) through an opening / closing valve V3, and an opening / closing valve V4 for supplying a chemical D from the chemical liquid tank T3. And an outlet of a chemical liquid supply path L8 to be supplied via the line. A float switch F is provided in the wash water storage tank T1, and when the stored wash water W is reduced to an amount that requires replenishment, the float switch F 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 for a predetermined time. When the sub tank T2 is not installed, it is desirable to provide a check valve instead to prevent the cleaning water from flowing backward.

  When this washing water circulation mechanism S is set to, for example, a two-stage washing method, the drainage flow path from the drainage port 11 is connected to the drainage pipe 12 side in the standby state, and the user stands in front of the toilet surface 10. When this is detected by the human body detection means 5, a small amount (for example, about 150 ml) of cleaning water W is discharged from the cleaning nozzle 6 as the initial cleaning at that time or immediately after the user leaves after urination, and the cleaning of the initial cleaning is performed. Water W and small water U are discharged to the drain pipe 12. Next, 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 L1 side, and a relatively large amount (for example, about 1000 ml) from the cleaning nozzle 6 as the main cleaning. The cleaning water W of the main cleaning is led to the cleaning water storage tank T1 through the recovery flow path L6 and recovered. Since the foreign matter is removed from the recovered washing water by the strainer 2 fitted in the drain port 11, troubles caused by the foreign matter mixing, for example, malfunction or stoppage of the circulation pump P1 and the discharge pump P2, It becomes difficult to cause clogging in the piping of the cleaning nozzle 6 and the flow paths L1 to L3, malfunction of the float switch F, and the like.

  In the embodiment, the strainer 2 has a circular shape in plan view as the strainer 2, but the deployable portion 22 can adopt various shapes such as an ellipse and a square depending on the specifications of the toilet surface 10. The shape and arrangement of the holes 20, the shape and number of the convex portions 23 and 24, the shape of the handle 25, and the like can be variously set in addition to the embodiment. On the other hand, the eye plate 3 needs to have an outer peripheral edge shape that can form the inflow / outflow gap g1 with the outer peripheral edge of the strainer 2, but is not limited to the form exemplified in the embodiment, and for example, the opening 31. A plurality of slit-shaped water holes arranged radially, a plurality of circular water holes arranged in a distributed manner, etc., a plurality of protrusions on the periphery instead of the rod-shaped leg pieces 32, and easy attachment / detachment It is also possible to use a knob provided with a knob or a hanging ring for making the ring. Further, the material of the strainer 2 and the eye plate 3 is not particularly limited, but the strainer 2 becomes a large size due to the presence of the developing portion 22, and the size of the eye plate 3 correspondingly increases accordingly. If it is made of synthetic resin, it is lightweight and easy to handle.

  The men's flush toilet of the present invention can employ various mechanisms other than those exemplified in FIG. 4 as the wash water circulation mechanism S, and also include those not having the wash water circulation mechanism S. In addition, in the present invention, detailed configurations such as the structure of the toilet body 1, the shape of the toilet surface 10, the structure of the drain outlet 11, the switching mechanism of the switching valve unit 4, the positions of the human body detection means 5 and the washing nozzle 6 are implemented. Various design changes can be made in addition to the form.
