Description

Detailed Description of the Invention

Industrial application fields

  The present invention relates to a flush toilet installed on the wall surface of a toilet room including not only a private house but also a public facility including an office building, a department store, a hotel, etc., in particular, the floor of the toilet room along or near the wall surface. The present invention relates to a flush urinal that can easily and reliably maintain cleanliness of a urinal body standing on a surface and a floor surface below the urinal body.

  The flush toilet generally comprises a substantially semi-cylindrical receiving surface portion standing along the wall surface of the toilet room, and a drooping receiving portion that is continuous with the lower portion thereof and extends substantially perpendicularly from the bowl portion having a discharge port. Then, a floor-standing type in which the bowl part and the tray receiving part are directly installed on the floor surface of the toilet room so that the receiving surface part stands upright, and the bowl part and the drooping receiving part are separated from the floor surface to receive a space below. It is roughly classified into a wall-mounted type that attaches the surface portion to the wall surface. In either case, water flows from the water supply section provided at the head of the receiving surface section through the water distribution holes along the entire inner peripheral surface of the receiving surface section, and the surfaces of the receiving surface section and the bowl section are washed with water and discharged from the discharge port. To do. Also, in many cases, the edge of both sides of the semi-cylindrical receiving surface portion and the edge of the rising portion of the drooping receiving portion that is continuous with it are passed through water from the water supply portion as a hollow rim, and the drooping receiving portion is received. This water is spouted from the water distribution hole provided along the inner peripheral surface of the section, the surface of the hanging receiving section is washed with water, and discharged from the discharge port. In both the floor-mounted type and the wall-mounted type, the drooping receiving part opens as much as possible and the rising part is sufficiently high, or the central part of the dripping receiving part protrudes toward the user. Therefore, the drooping effect is improved.

  Water supply to the water supply unit is performed by a water pipe connected to the water supply hole of the head through the valve body, and the user who has used the plug opening device linked to the valve body is manually operated, It is automatically activated by sensing the separation from the user's urinal or the approach and separation by a sensor such as an ultrasonic wave, and washing with water is performed.

  Regardless of the washing with the water flow as described above, generation, adhesion and accumulation of urinary stones are inevitable if frequent use is repeated, and there is no countermeasure other than cleaning by manual cleaning personnel. The problem in this manual work is the back side of the rim at the side edges of the receiving surface and the rising edge of the drooping receiving portion, that is, the front side where the user stands or the shadowed surface of the step that cannot be seen from above. In the case of floor-standing type, the floor surface outside the drooping receiving part, and in the case of wall-mounted type, the floor surface below the dripping receiving part, that is, it is not subject to water washing, so manual cleaning is indispensable In addition, it is a part including joints between tiles to which urine stones easily adhere. Furthermore, although the outer surface of the drooping receiving portion is also subject to contamination, urine on the outer surface of the dripping receiving portion flows and stays on the outer bottom surface of the bowl portion or the attachment portion to the wall surface particularly in the case of the wall-hanging type. Of these parts, the rim can be solved by eliminating the stepped shape that protrudes from the inner surface of the toilet, but the problem of dirt on the floor can be reduced by reducing the burden on the cleaner by configuring the toilet. In view of the possibility, various solutions have been proposed.

  For example, a urinal described in JP-A-1-287328 includes a floor cleaning device that sweeps and cleans the floor surface with a cleaning brush that reciprocates back and forth on the floor surface under the urinal standing on the wall surface. The cleaning water is supplied to the cleaning brush by another pipe from the water supply source to the urinal. Japanese Utility Model Laid-Open No. 6-26693 describes a configuration in which a recessed portion for drainage is provided below or around the hanging receiving portion of a floor-standing and wall-mounted urinal, and this is covered with a water-permeable cover. However, the water-permeable cover in this case is washed with water by the cleaning staff. In another embodiment, the floor surface is inclined downward from the wall surface opposite to the wall surface where the wall-mounted urinal is installed, and when a human body is detected by a sensor, the nozzle on the opposite side wall surface is opened and water flows on the floor surface, The water whose floor is washed is discharged from the drainage channel below the urinal. In Japanese Utility Model Laid-Open No. 3-125875 showing a toilet booth cleaning device, both sides and the lower side of a wall-mounted urinal are surrounded by wall portions projecting from a front mounting wall, and a plurality of water outlets provided on these wall portions are used. A configuration is disclosed in which water is sprayed and washed on the outer surface and floor surface of a urinal and drained from a drain outlet on the floor surface. Furthermore, in the floor-mounted male toilet proposed in Japanese Patent Application Laid-Open No. 2004-316211, the edge surfaces on both sides of the box-type main toilet placed on the floor and the standing of the drooping receiving portion below the both sides are provided. On the edge surface of the raised part, a drainage basin for flowing water from the water supply part at the head of the main toilet to the inside of the hanging receiving part is formed, and the drainage of the main toilet is attached to the foot tray connected to the front of the lower part of the main toilet. A recess having a drain outlet connected to the road is provided, a grid-like stepping plate is placed on the upper surface thereof, and cleaning water is supplied to the upper part of the inner surface of the main toilet bowl, the bowl for running water, and the concave inner periphery of the foot tray, and the inner surface of the main toilet bowl and its The structure which can also wash | clean the floor surface in front of a drooping reception part simultaneously with the washing | cleaning of a both-sides edge surface, the drooping receiving part inner surface, and its edge surface is disclosed. In addition, the “Public Toiletology Declaration” written by Motoho Kimura (Economic Research Committee 1994) (http://www.tsubasa.to/dreams/html/90-05.html) shows the lower part of the wall-mounted urinal. It is shown that a drooping water washing part having a small area is provided on the floor surface below the drooping receiving part protruding to the user side, and water is also poured into the dripping water washing part after the toilet to wash it.

Problems to be solved by the invention

  Although the floor cleaning device of Japanese Patent Laid-Open No. 1-287328 is suitable for the cleaning effect of the floor surface under the urinal, it is clear that it is too expensive to manufacture and maintain, and the hanging of the wall-mounted urinal There is no cleaning effect against dirt on the outer peripheral surface and bottom surface of the receiving portion. Compared with this apparatus, the drainage recess on the floor surface of Japanese Utility Model Laid-Open No. 6-26693 can be manufactured at low cost, but requires artificial cleaning, and the outer peripheral surface of the drooping receiving portion still relies on human cleaning. Moreover, even if there is a cleaning effect on the floor surface, the structure in which the floor surface is made to have a gradient causes a danger to the pedestrian, and it is unsafe for the dirt on the outer surface of the hanging receiving portion with the wall. In that respect, the toilet booth with a cleaning device of Japanese Utility Model Laid-Open No. 3-125875 is designed to clean the entire outer surface of the urinal including the outer peripheral surface and bottom surface of the sag receiving portion, and the edge surfaces of both side walls at the same time as the floor surface below the urinal. However, it is difficult to reduce the wall thickness because the wall on the front and both sides that form the toilet booth has built-in valve devices and water distribution pipes for multiple outlets. In addition, not only the manufacturing cost increases, but also the width dimension increases, which is disadvantageous when a plurality of toilet booths are juxtaposed in a limited space. Furthermore, in the case of Japanese Patent Laid-Open No. 2004-316211, since the flushing basins are provided on the edge surfaces of the both side walls of the main toilet, the point that these edge surfaces can be washed is epoch-making, but It remains unwashable. In addition, it is also epoch-making that a foot tray is provided on the floor surface outside the drooping receiver, and cleaning water is supplied into the concave surface, but urine scattered outside the drooping receiver is a grid-like stepping plate that covers the concave surface. Despite falling directly on, the cleaning of the grid footboards still relies on human hands. The foot tray is also made separately from the main toilet and is connected to the lower front of the main toilet so as to connect the drain hole of the tray to the drainage channel. Prone to occur. On the other hand, if these problems remain unresolved and the phenomenon of an aging society progresses, not only will the amount of urine splash outside the toilet increase, but also the problem that the area of scattering will not be overlooked. Become. In addition, in the case of wall-mounted urinals of the “Public Toiletology Declaration”, since it is wall-mounted, it is necessary to take measures against drooping on the floor separately from installation of drooping parts protruding from the wall. In addition to the inevitable contamination and accumulation of the outer periphery, as for the sag splashing out of the sag receiving part, as shown in this document, the small area spilled water washing part provided on the floor surface falls directly below It is only effective for the sag and is completely powerless against dripping in all directions.

  The present invention has been proposed to solve the above-described problems in the prior art, and the main body, which is a receiving surface portion of a urinal, is a floor-standing type, and the height of the floor surface below the receiving surface portion that receives urination is set. A floor body including a sink portion and a step portion connected to the sink portion where the user stands on the foot is integrally formed at the lower part of the main body, and the step is performed together with the cleaning fluid from the receiving surface portion to the sink portion. By supplying cleaning fluid from the unit to the sink unit, it is possible to clean the main body and the floor surface that are subject to contamination with a simple structure that does not cause a significant increase in cost and without relying on human hands. An object is to provide a cleaning urinal.

Means for solving the problem

  A fluid cleaning urinal according to the present invention includes a main body including a receiving surface portion that is erected and receives a user's urination, and a floor body including a sink portion that faces a lower end of the receiving surface portion at a level of the floor surface on which the user stands. It consists of a fluid supply device that supplies the main cleaning fluid flow to the receiving surface part of the main body, the main body and the floor body are integrally formed, the floor body is continuous to the sink portion and extends to the level of the floor surface, and the user can The fluid supply device further includes a sub-cleaning fluid flow that flows through almost the entire surface of the step portion of the floor body to the sink portion.

The vertical water channel and the horizontal wall of the floor that extend from the lower end of the vertical water channel and have water spray holes provided toward the upper surface of the step part and a secondary water washing flow that flows to the sink part through the upper surface of the step part It is characterized by comprising flushing means.

  The fluid supply device further includes a flushing means for generating a flushing flow that flows from the upper part of the receiving surface part of the main body through the entire surface thereof to the sink part of the flooring body, and an air flow from the air tank inside or outside the main body. It comprises cleaning airflow means that flows as a gas flow of the sub-cleaning fluid flow from the peripheral wall through the upper surface of the step portion to the sink portion.

  The width between both side edges of the receiving surface portion of the main body and the width between both side walls of the floor body are substantially the same, the inner peripheral surface of the receiving surface portion is formed continuously with the inner peripheral surface of the sink portion, and the upper surface of the step portion Is characterized in that it is formed continuously on the inner peripheral surface of the sink part between the both end faces of the receiving surface part.

  The width between both side edges of the receiving surface portion of the main body is smaller than the width between both side walls of the step portion of the floor body, and the sink portion has a main portion whose inner peripheral surface is continuous with the central portion of the inner peripheral surface of the receiving surface portion, In the vicinity of both side edges of the receiving surface part, the upper surface of the step part is formed between the both side edges of the receiving surface part between the side edge of the receiving surface part. The main part is characterized in that it continues to the bulging part of the sink part on the outside of both side edges of the receiving surface part.

  The fluid supply device also has a sprinkler that sprays water as a main cleaning fluid flow on almost the entire circumferential surface at the upper part of the receiving surface of the main body, and an inner side from a position above the lower center of the receiving surface to the vicinity of the lower ends of both side edges. And a slanted step portion that sprinkles a part of the main cleaning fluid flow as an auxiliary cleaning fluid flow on the upper surface of the floor body step portion.

Action

  The fluid cleaning urinal of the present invention includes a main body including a receiving surface portion that is erected on a floor surface on which a user stands and receives urination of the user, and a sink portion that faces a lower end of the receiving surface portion at the floor surface level. The body and the fluid supply device that supplies the cleaning fluid flow to the receiving surface of the main body, in particular, the main body and the floor body are integrally formed, and the floor body is continuous with the sink portion. And a step portion on which the user rests on the floor surface is provided, and the fluid supply device not only supplies the main cleaning fluid flow to the main body receiving surface portion, but also substantially on the entire step portion of the floor body. Since the sub-cleaning fluid flow is also supplied, the sub-cleaning fluid flow that cleaned the step portion flows into the sink portion connected to the step-cleaning fluid flow and is discharged together with the main cleaning fluid flow. That is, the receiving surface part to be contaminated during urination and the floor surface below the same are continuously integrated with the sink part in the urinal of the present invention and are simultaneously washed.

  In the fluid cleaning urinal according to the present invention, at least the sub-cleaning fluid flow of the fluid supply device is made into a pressurized gas flow, the dirt on the upper surface of the step portion is blown off to the sink portion, and the main cleaning fluid flow to the receiving surface portion of the main body is washed with water. Flow. In this case, the main cleaning fluid flow can be a gas flow, but in particular the pressurized gas flow as the secondary cleaning fluid flow is supplied into the user's stool, separately from the supply to the step section, or In combination, it is also possible to catch the falling urine drop on the way and spray it on the receiving surface part by ejecting it obliquely upward toward the main body receiving surface part from between both feet.

  The fluid supply device is also formed with main water flushing means for generating a main washing fluid flow that flows from the water supply part of the main body head to the sink part of the floor through the entire receiving surface part, and from the water supply part to the lower end of the receiving surface part inside the main body. Since it is composed of a sub-water washing means that generates a sub-cleaning fluid flow that flows from the water spray hole of the horizontal water channel provided in the peripheral wall of the floor body through the upper surface of the step portion to the sink portion continuously to the vertical water channel. The contaminated surfaces of the main body and the floor body are cleaned by the main flush flow and the secondary flush flow that are simultaneously supplied from the water supply unit.

  In the fluid supply device, the main cleaning fluid flow that flows from the upper portion of the receiving surface portion of the main body to the sink portion of the floor body through the entire surface is used as a flush flow by the flush flow means, while the auxiliary cleaning fluid flow is either inside or outside the main body. The air flow from the air tank provided in the crab is supplied to the upper surface of the step portion through the peripheral wall of the floor body, and is made into a gas flow by the cleaning air flow means for flowing to the sink portion. Therefore, while the receiving surface portion is washed with a water-washing flow, the upper surface of the stepped portion of the floor on which the user is placed is cleaned with an air flow and kept dry. The air stream carrying the dirt is guided to the sink part by the water washing flow flowing down from the receiving surface part. In this case, it is advantageous if the upper surface of the step portion has water repellency.

  Further, in the fluid flushing urinal of the present invention, the width between both side edges of the receiving surface portion of the main body is formed to be substantially the same as the width between both side walls of the step portion of the floor body, so that the inside of the receiving surface portion and the sink portion is The peripheral surfaces are continuous with each other, and the upper surface of the step portion is configured to be continuous with the inner peripheral surface of the sink portion between both side edges of the receiving surface portion, that is, over almost the entire width of the step portion. Therefore, the receiving surface portion and the step portion can receive scattered urine with the maximum width and can be washed away.

  In the fluid flushing urinal of the present invention, the width between both side edges of the receiving surface portion of the main body is made larger than the floor body and smaller than the width between both side walls of the step portion, while the sink portion in the receiving surface portion is the step portion. The upper part of the step part is the main part of the sink part between the two edges of the receiving surface part. And all of the swelled portion of the sink part on both outer sides of the edge. In this way, even in a public toilet room where a plurality of urinals are installed, the width of the step portion is large and the width of the receiving surface portion is relatively small so that a space is provided between the receiving surface portions of adjacent urinals. However, the entire surface of the step portion can be cleaned.

  Further, the fluid supply device includes a water sprinkler for spraying water on substantially the entire peripheral surface of the upper portion of the receiving surface portion of the main body as a means for generating the main cleaning fluid flow. A slope that protrudes inward from the position raised from the lower end to near the lower end of both side edges is formed, and a part of the main cleaning fluid flow is formed by a slanted step portion that sprays water toward the upper surface of the step portion of the floor body. In this case, the main body integrated with the floor body holds the receiving surface portion obliquely, and the lower end of both end edges of the receiving surface portion protrudes above the step portion and separates the lower end of the receiving surface portion from the floor body, thereby spraying the sub-cleaning fluid flow. Make it effective

  Several specific embodiments of the fluid flushing urinal according to the present invention will be described below with reference to the accompanying drawings.

  1 and 2 show a first embodiment of a fluid flushing urinal according to the present invention, FIG. 1 is a central longitudinal sectional view of the fluid flushing urinal along the line II of FIG. 2, and FIG. It is a cross-sectional view along the II-II line.

  The fluid cleaning urinal according to the present embodiment generally includes a main body 10 erected along the wall surface of the toilet room, and a floor body 20 that is integrally formed at a lower portion of the main body 10 and fixes the urinal to the floor surface of the toilet room. And a fluid flow device 30 provided at the head of the main body 10. In general, the main body 10 including the head constituting the fluid flow device 30 and the floor body 20 are made as an integrated ceramic or porcelain product, but may be a product made of other materials such as resin and metal.

  The main body 10 includes a receiving surface portion 11 having a semi-cylindrical or box-shaped inner peripheral surface having a semicircular or parabolic cross section for receiving urine discharged by the user, and the edges 12 on both sides of the receiving surface portion are the user. The width is wide enough to contain the front surface, and each edge 12 does not fold inward, but has a slope or a semi-cylindrical shape that opens outside, eliminating the portion where urine or urine stone adheres and stays, and cleaning work Easy cleaning by personnel.

  The floor body 20 is formed integrally and continuously with the lower portion of the main body 10, but the floor body 20 has a drain port 21 at the deepest part of the substantially hemispherical inner peripheral surface that is continuous with the inner peripheral surface of the receiving surface portion 11. A sink portion 22 and a step portion 24 having an upper surface 23 that extends in a rectangular shape from the lower end of both side edges 12 of the receiving surface portion 11 to the side opposite to the sink portion 22 are provided. Although the upper surface 23 is inclined mainly toward the sink portion 22, a plurality of protrusions provided in parallel with each other on the upper surface 23 so that the user can easily stand with the feet on the step portion toward the receiving surface portion 11 for stool. So that the ridgeline is almost horizontal as a whole. In the drawing, these ridges are shown as being provided in parallel to the vertical direction in which the user stands toward the receiving surface portion. However, if the ridges are replaced with such ridges to form a plurality of protrusions, the arrangement is free. Further, the ridges of the ridges or the top surfaces of the protrusions give the user a further sense of stability by omitting the glaze or by attaching a non-slip material to the friction surface.

  The fluid flow device 30 includes a water supply unit 31 provided at the top of the main body 10, a vertical water channel 34 formed in the side edges 12 of the receiving surface unit 11 from the water supply unit 31 to the lower end of the receiving surface unit, and a step unit of the floor body 20. The horizontal water channel 35 is provided with a plurality of water spray holes 36 that are continuous with the lower end of the vertical water channel 34 at one end in the both side wall portions 24, extend into the rear wall portion through the both side wall portions, and open toward the upper surface 23 of the step portion. It consists of. Water supply to the water supply unit 31 is performed from a water tap (not shown) through a water supply port 32 penetrating the top wall when, for example, the infrared sensor 37 provided on the front surface detects that the user has left the urinal. A part of the supplied water is used as the main flushing flow in the entire receiving surface portion through a plurality of water spray holes 33 penetrating at a position along the upper end of the inner peripheral surface of the receiving surface portion 11 of the bottom wall. The other part of the water in the water supply unit 31 is used as a secondary flush flow that flows into the horizontal water channel 35 of the floor body 20 via the vertical water channels 34 in the side edges 12 of the receiving surface unit. It is spread over the upper surface 23 in general. At that time, watering may be performed from above the ridges or protrusions, or may be performed on the valleys between the ridges or protrusions, or a combination of both, but in general, the entire upper surface of the step part Is to wash. The sub-water washing flow that has cleaned the upper surface of the step portion flows into the sink portion 22 and is discharged from the drain port 21 together with the main water washing flow that has washed the receiving surface portion 11.

  In the above description, both the main flush flow and the secondary flush flow are described as being based on water, but at least the secondary flush flow may be a gas flow such as pressurized air or water vapor. In this case, for example, an air tank 38 is provided at a position where the water supply unit 31 is divided and communicated with the vertical water channel 34, and a gas flow is supplied to the vertical water channel 34 and the horizontal water channel 35 and sprayed from the sprinkling holes 36 onto the step unit upper surface 23. If the upper surface of the step part has water repellency, the cleaning power of the gas flow is high.

  In this embodiment, the width of both side edges 12 of the receiving surface portion 11, particularly the width between the lower ends thereof, is shown as being the same as the width of the step portion 24 of the floor body 20 as seen in FIG. By making the width of the receiving surface 11 as large as possible, all the urine and scattered urine are received, and at the same time, the width of the floor body 20 is set to a size sufficient for the user to stand with the legs slightly open. It is intended to receive the entire width of the sub-water washing flow flowing over the upper surface 23 of the step portion 24 having a sufficiently large width and drop it into the sink portion 22. Therefore, the width relationship between the receiving surface portion 11 and the step portion 24 can be appropriately changed according to the design intention.

  For example, in the case of a toilet room for public use, the distance between the center lines of adjacent urinals is 80 cm in the Japanese Industrial Standard, so that the width of the floor 20 of the urinal of the present invention and at least the lower end of the receiving surface 11 The width can be freely selected up to a maximum of 80 cm, but in order to completely receive urination and scattered urine, the width of the receiving surface should be as large as possible, and the user opens both feet at the step part. Considering that it is possible to provide a wide enough area to stand up, it is preferable that it is practically around 50 to 60 cm. On the other hand, it is possible to make the width of the floor 20 larger than the width of the receiving surface portion so that the upper surface of the step portion protrudes on both sides of the lower end of the receiving surface portion. It is desirable to provide a means for accommodating the sub-water washing flow in which the entire upper surface of the step portion is washed in the sink portion without overflowing or overflowing from the protruding portion.

  FIG. 3 and FIG. 4 show a second embodiment of the present invention that uses an example of the above-described sub-water washing means. As apparent from FIG. 4, if the width of the floor 20 is, for example, about 60 cm and the width between both side edges 12 of the receiving surface portion of the main body 10 is about 50 cm, the floor is formed on both outer sides of each edge 12. The upper surface of 20 is exposed with a width of about 5 cm. Also in this case, the horizontal water channel 35 and the water spray hole 36 for cleaning the upper surface of the step portion are provided in the rear wall portion of the step portion 24 so as to be almost full of the width of the floor body 20, and the water from at least the outermost water spray hole 36 in the width direction. Reaches the outside of the receiving surface edge 12, so that it can serve as a means for storing the sub-washing flow in this portion, from the lower end of the receiving surface edge 12 to the position recessed in the vertical direction, through the receiving surface lower end and from the inside of the receiving surface to the outside. In the widthwise direction, there is provided a bulging sink portion 22a in which a part of the sink portion 22 is extended on both sides, and the sub-water washing flow that flows outside the receiving surface edge 12 flows into the bulging sink portion 22a, and the direct sink portion The sub-water washing flow that has flowed into 22 is joined to the drain outlet 21. In this case, both side edges 12 of the receiving surface portion are more likely to be contaminated with scattered urine because the width between them is smaller than the width of the floor body 20, but each edge portion is user-friendly as seen in FIG. It opens at an acute angle and is formed so as to be cleaned by the main water washing flow with respect to the receiving surface portion 11, and the outer peripheral surface of the receiving surface portion is not opened and contaminated to the user. Further, as shown in FIG. 3, the lower end of the receiving surface portion is cut from the lower end of the edge 12 along the upper surface of the floor body 13 so that the bulging sink portion 22a and the sink portion 22 communicate with each other. It is also possible to adopt a configuration in which only the lower end portion of 12 is connected to the upper surface of the step portion.

  Next, with reference to FIG. 5, a third embodiment using a floor structure step unit configuration different from the first and second embodiments described above will be described. In this embodiment, the configurations of the main body 10, the floor body 20 and the fluid flow device 30 are substantially the same as those of the first and second embodiments, but a plurality of protrusions constituting the step portion upper surface 23 of the floor body 20. Alternatively, instead of the protrusion, a highly water-permeable plate-like step member 25 laid on a flat upper surface 23 inclined from the rear wall side of the step portion 24 toward the sink portion 22 is used. The auxiliary flush flow supplied from the water supply unit 31 of the main body 10 to the horizontal water channel 35 in the rear wall of the step unit 24 via the vertical water channel 34 from the rear end facing the water spray hole 36 to the front end facing the sink unit 22. After passing through the step material 25 and cleaning, it is discharged to the sink part 22. A friction surface is provided on at least a part of the upper surface 23 of the step part, or a stopper is provided on the front end of the sink part side so that the step material 25 does not slide due to the load of the user. As the material of the step material 25, it has high water permeability, in other words, it has a high porosity in order to obtain a property of high water permeation rate, and there is almost no compression even when the user is loaded and receives a load. A linear, coarse fiber, or sponge-like inorganic material, synthetic resin material, or metal material showing hardness or pressure resistance is used. More desirably, a composition having an odor decomposition function such as titanium oxide is included as the step material. In addition, if it does not matter that some manpower is required for cleaning, for example, it is possible to use, as a step material, a stainless steel plate that is detachably disposed with water permeability, a non-slip surface or water repellency.

  In the fourth embodiment shown in FIGS. 6 and 7, the sub-cleaning fluid flow of the fluid supply device 30 is a part of the main cleaning fluid flow supplied to the inner peripheral surface of the receiving surface portion 11 of the main body. Produced by means of diverting towards the upper surface 23 and spreading. This spraying means has a starting point 39a at a position above the receiving surface portion lower end 11b of the central region as viewed from the user standing on the floor body step portion 24 of the receiving surface portion 11 of the main body 10, and the receiving surface portion from the starting point 39a. It is composed of a concave sloped stepped portion 39 having a concave slope projecting inwardly while gradually increasing its width toward the lower end 12a of each edge 12 on both sides, obliquely downward along the inner peripheral surface of the receiving surface portion. The terminal end 39 b of the obliquely stepped portion 39 extends toward the step portion 24. Accordingly, at the upper end 11a of the receiving surface portion, a part of the water that is diffused almost entirely on the inner periphery of the receiving surface portion 11 by the sprinkler 31a and descends the receiving surface portion 11 as the main cleaning fluid flow is end along the upper surface of the oblique step portion 39. The sub-cleaning fluid flow is diverted obliquely in the direction of the edge lower end 12a, and sprayed from the terminal end 39b toward the upper surface 23 of the step portion 24. In order to increase the spraying effect of water from the edge lower end 12a portion of the receiving surface portion, as shown in FIG. 6, in this embodiment, the main body 10 is slightly inclined over the entire receiving surface portion 11 and the lower end is a floor body. The receiving surface part lower end 11b faces the inner peripheral surface of the sink part 22 of the floor body and the upper surface of a part of the step part 24 connected to the sink part from above. The configuration is separated from the floor body 20. Therefore, the water of the main cleaning fluid flow that flows down by washing the inner peripheral surface of the receiving surface portion 11 falls from the receiving surface portion lower end 11 b and is accommodated in the sink portion 22. The main body 10 holds the receiving surface portion 11 at the upper portion and is formed integrally with the floor body 20 at the lower portion. The upper surface 23 of the step portion 24 may include any one of the protrusions or protrusions in the first and second embodiments and the step material of the third embodiment.

  Although the configuration of the fluid cleaning urinal of the present invention has been described above for several embodiments, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the claims. Is possible. For example, in any of the embodiments, the sub-cleaning fluid flow with respect to the upper surface of the step portion of the floor body is shown as flowing in the vertical direction from the rear wall side toward the sink portion by a horizontal water channel extending from both side walls of the step portion to the rear wall. However, it may be allowed to flow laterally from both side walls, or without a horizontal water channel, it may be opened directly from the lower end of the vertical water channel, that is, from the lower end of both side edges of the receiving surface part toward the upper surface of the step part. Is possible. Also, the vertical water channel is not located inside the edge of the receiving surface part, but on the back part of the receiving surface part, and is connected to the horizontal water channel provided from the side wall to the rear wall of the floor, only the side wall, or the lower edge of the receiving surface part. Also good. Furthermore, although the slanting step portion of the fourth embodiment is shown in combination with the configuration in which the receiving surface portion is inclined and the lower end is separated from the floor body, the combination is not limited to this separation configuration, and the first embodiment is integrated. It can also be combined with the configuration.

  The configuration in which the cleaning fluid flow is supplied to the receiving surface portion and the step portion at the same time and both flows are drained from the sink portion below the receiving surface portion is a remarkable feature of the present invention. As an example, it is possible to allow the entire fluid flow of cleaning the receiving surface portion to pass through the step portion and then drain from a sink portion provided on the rear wall side of the step portion. However, in this case, urination once stays in the lower part of the receiving surface in the user's stool, so as not to give a sense of filth due to urination flowing under the user's feet placed on the step part. There is a need to. Further, as another configuration in this case, the sink portion is extended from the lower portion of the receiving surface portion to the lower portion of the step portion, and the step portion is formed of a highly rigid, highly water permeable and detachable member and is provided on the inner peripheral surface of the receiving surface portion. It is also possible to adopt a configuration in which a part of the main cleaning fluid flow is sprinkled on the upper surface of the step member by the stepped portion. Further, when using the step portion or step member as in the above-described example, including the first to fourth embodiments, a cleaning effect can be obtained if the surface of the step portion is water-repellent.

The invention's effect

  As is apparent from the above description, according to the fluid flushing urinal of the present invention, in a configuration where the whole is a floor-standing type, a main body that is a receiving surface portion that receives urine, a sink portion that faces the lower end of the receiving surface portion, and this A floor body consisting of a step portion that is continuous with the sink portion and the user stands on both feet is integrally formed, and the receiving surface portion is washed to flow the fluid flow to the sink portion and the step portion to flow to the sink portion. Since the fluid flow is supplied by the fluid supply device, the peripheral wall surrounding the droop receiving part that follows the sink part, which has been indispensable in the past, is omitted, and the user stands and receives drooping urine and scattered urine. The step portion corresponding to the floor surface that had to wait for can also be cleaned at the same time as the receiving surface portion or at a different timing. Therefore, the fluid cleaning urinal of the present invention has a simple configuration and exhibits a very great effect that the step part for receiving the suspended urine and the scattered urine can be cleaned without the need for manpower as well as the urination receiving surface part.

  Integration of the main body and the floor body integrates the receiving part and the step part to maximize the width of both sides, providing a continuous space without any partition between them, and the user has enough feet This makes it possible not only to open the stool and add stool, but also to completely capture urine scattered over a wide area, particularly when urination is completed.
