Description

  The present invention includes a flooring having a function of cleaning a floor surface mainly contaminated with liquid droplets, a flush toilet comprising a floor using the flooring combined with or integrated with a toilet body, and The present invention relates to an assembly of a floor body using a flooring material and a flush toilet.

  Toilet rooms in various public facilities as well as private houses, especially the floor around the toilet, are contaminated with urine droplets excreted by the user each time they are used. It is desirable to clean the contaminated floor surface at an early stage, but the measure for that is first a manual wiping or washing operation. In public facilities, a specialized cleaning worker is required for this operation. . While this category has reduced the number of candidates in recent years, it has increased the cost of hiring professional workers. Therefore, various devices or facilities for cleaning the floor surface around the toilet without mechanical intervention have been proposed.

  For example, a urinal described in JP-A-1-287328 is a floor cleaning device that sweeps with a cleaning brush that reciprocates back and forth with respect to the wall surface on the floor surface under the urinal erected on the wall surface. The cleaning water is supplied to the cleaning brush through a separate pipe from the water supply source for the urinal and drained from the drain pan below the floor.

  As an example, Japanese Utility Model Laid-Open No. 6-26693 provides a drainage recess on the floor below or around the stool receiving part of the urinal in both the floor-standing type and the wall-mounted type, and this is provided with a water-permeable cover. A structure in which the water permeable cover is washed with water by a cleaning worker is disclosed. 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, the human body is detected, water is washed from the nozzle on the opposite side wall surface to the floor surface, and the urinal is washed. The structure of the toilet room which drains from the lower drainage groove is disclosed.

  In Japanese Utility Model Laid-Open No. 3-125875 which discloses a toilet booth cleaning device, a plurality of water outlets are provided on both sides and lower sides of a wall-mounted urinal that are surrounded by a wall portion projecting from a front mounting wall and provided at the base portion thereof. A configuration is proposed in which water is sprayed and washed on the outer surface and floor surface of the urinal and drained from a drain outlet provided on the floor surface.

  In the toilet floor cleaning apparatus described in Japanese Patent Application Laid-Open No. 8-103399, in order to wash away the earth and sand falling from the user's footwear, a water spray pipe extending in the width direction of the toilet is pivoted at a certain angle on the front and back walls of the toilet. Rotate to reciprocate the water sprayed on the floor.

  In the floor-mounted male toilet proposed in Japanese Patent Application Laid-Open No. 2004-316211, the sag is received from the end surface of both side walls of the main toilet erected on the floor and the end surface of the sag receiving part below the main stool. A drainage port connected to the drainage channel of the main toilet is connected to the floor tray connected to the floor below the main toilet, while a drainage basin is provided over the section so that the dirt on the edge surface can be cleaned. A recess is provided, a grid-like stepping plate is placed on the upper surface, and after use of the toilet, cleaning water is supplied to the inner surface of the main toilet, the flushing basin, and the inner periphery of the recess of the foot tray, and the floor under the toilet is also cleaned at the same time. The configuration is shown.

Further, the flush urinal described in Japanese Patent Application Laid-Open No. 6-26090 is provided with a small area flush basin on the floor surface below the sag receiving portion protruding to the user side at the bottom of the wall-mounted urinal. After use, wash the urinal body and the hanging pan at the same time.
JP-A-1-287328 ACT 6-26693 ACT 6-26693 Japanese Utility Model Publication No. 3-125875 JP-A-8-103399 JP 2004-316211 A JP-A-6-26090

In the floor cleaning device disclosed in Japanese Patent Laid-Open No. 01-287328 described above, a washing machine with a horizontally long rotating brush that is normally stored in the lower part of the wall surface where the urinal is erected is provided with a predetermined operation from the operation of a water supply knob for urinal washing. While being driven by a motor after time and receiving water supply, it moves in the direction away from the wall surface along the floor surface of the floor panel that forms the drainage pan below it and turns back and forth from the rear end of the floor panel. Clean the floor with a brush and water. The washed water flows down to the drain pan and is discharged from the drain outlet. Although this configuration has a high floor cleaning effect without an attendant, the structure is complicated and includes the problem that it is too expensive to manufacture and maintain.

The floor drainage recesses of Japanese Utility Model Publication No. 06-26693 require artificial cleaning, and even if the configuration of cleaning the floor surface with running water with a gradient is effective, the floor surface in general In this invention, a small protrusion is provided on the floor surface as a slip stopper. However, the small protrusion may be dangerous, and requires an extra cost. That is certain.

The toilet booth with a cleaning device of Japanese Utility Model Publication No. 3-125875 is advantageous in that it cleans the lower floor as well as the inside and outside of the urinal at the same time, but the front and both side walls forming the toilet booth have many water outlets, Since the on-off valve device and the water distribution pipe are built in, the wall thickness becomes large and the manufacturing cost increases, which is disadvantageous when a large number of toilet booths are installed in a limited space.

In the case of Japanese Patent Application Laid-Open No. 8-103399, the structure is complicated in that a device for rotating the sprinkler tube is required, and a considerable amount of water is required for the sprinkled water to reciprocate on the floor surface. This also increases the cost.

The urinal of Japanese Patent Application Laid-Open No. 2004-316211 is epoch-making in that it is grounded that a flushing basin is provided on the edge surfaces of both side walls of the main toilet and the dirt on these edge surfaces is cleaned. Remains unwashable. In addition, it is also epoch-making that a foot tray is provided on the floor surface outside the drooping receiving portion and the inside of the concave surface is washed. However, washing of the grid-like stepping board on which scattered urine falls directly remains as a manual operation.

In Japanese Patent Application Laid-Open No. 6-26090, since a water-washing-type drooping tray having a small area is only provided on the floor, below the drooping receiving portion of the urinal body, Is effective, but it is powerless against splashes that spread out without falling vertically, and the floor around the drip pan must still wait for manual cleaning.

Both of these prior arts suggest that the urination dripping and splashing contamination on the floor area around or below the toilet bowl, or on the floor surface of the entire toilet room, is automatically or manually cleaned. . In the case of residential use, the water is usually washed by a manual valve opening operation, but in the case of automatic in public facilities, it is usually detected every time the user leaves the toilet for each toilet, and for a certain time or a certain amount of water Irrespectively, the plurality of toilets are intermittently washed at certain time intervals regardless of whether or not they are used. The amount of water required for a single flush of the toilet bowl is generally about 6 liters for urinals and about 12 liters for toilets (“Dreams on a Railway-”; http: // www. tsubasa.to/dreams/html/90-05.html), even though the water-saving flush toilets have recently become widespread and the amount of water has been reduced considerably, the amount of flush water on the floor around the toilet can be added. For example, it is clear that a very large amount of water is consumed for automatic flushing of toilet bowls and toilet floors. The present invention solves this problem, and particularly reduces or eliminates the amount of water required for cleaning or cleaning the floor, while at the same time being limited to a limited area around or below the toilet. Another object of the present invention is to make it possible to clean a wide range of floors covering at least the lower part or the entire surface of a toilet room in which a plurality of toilets are placed, and eliminate the need for an artificial cleaning operation.

The present invention has been proposed in order to solve the above-described problems in the prior art, and not only automatically and reliably cleans the floor surface due to splashes of liquid such as scattered urine but also drops. An object of the present invention is to provide a flooring material having a function of capturing and removing the scattered urine droplets before reaching the floor surface.

  The present invention also uses the floor material having the function of cleaning the floor surface described above for the floor surface portion on which the user's feet are placed in relation to the toilet bowl, and is mainly used for washing after use of the toilet body. An object of the present invention is to provide a urinal that can separately clean the floor portion.

  It is another object of the present invention to provide an assembly in which a floor material having a function of cleaning the floor surface is combined with one or more flush toilets.

  In order to solve the above-mentioned problems, the flooring with a cleaning function of the present invention includes a nozzle that is opened on the surface of a plate-like flooring from one end side to the other side of the flooring, and a nozzle provided on the flooring. A connected inlet, a pressurized air supply device that supplies pressurized air to the inlet and generates a jet jet covering the surface of the flooring from the nozzle, and a jet jet at a downstream position of the jet jet on the other end of the flooring The jet jet captures droplets falling from above the floor material surface before reaching the floor material surface and separates droplets adhering to the floor material surface. It is carried to the downstream position and collides with the wall of the gas-liquid separation device to separate the liquid component downward and the gas component upward.

[Action]

  The flooring with a cleaning function, which forms the basis of the present invention, is opened in one direction from one end side to the other end side of the plate-like flooring material and spreads along the surface of the flooring material, and on the surface of the flooring material. The high pressure air is supplied to the nozzle provided through the introduction port provided on the other surface of the floor material by the high pressure air supply device, thereby forming a jet jet covering almost the entire surface of the floor material and falling from above. Drops such as urine are captured before reaching the floor surface, and droplets already adhering to the floor surface are separated and captured, and the gas-liquid separator is jetted at a downstream position on the other end side of the floor material. The wall of the jet that intersects the jet at right angles allows the separation of the liquid component of the jet jet in the downward direction and the gas component in the upward direction, and the surface of the flooring is automatically cleaned.

  As explained in detail above, according to the flooring with a cleaning function of the present invention, a nozzle having a spread along the surface is provided on the surface of the plate-like flooring, and this nozzle causes the other end from the one end side of the flooring. A jet jet that covers almost the entire surface of the flooring is generated, so a urinal splash is scattered by the user of these toilets by placing a toilet in the middle area of this jet stream or a urinal in the downstream area. Before reaching the floor material surface, or if it has already adhered to the floor material surface, it is peeled off and placed on a jet jet to prevent and clean the floor material surface. Furthermore, since the gas component and the liquid component are separated in the downstream area of the jet jet, the liquid, that is, the urine component is drained together with the flushing flow of the toilet, and the gas component attenuates the flow velocity, so that it can be easily processed.

  Hereinafter, several specific examples of a flooring with a cleaning function according to the present invention and a flush toilet, a urinal and a urinal assembly combined with the flooring will be described with reference to the accompanying drawings. To do.

  FIG. 1 shows a flooring 10 with a cleaning function having a basic configuration in Example 1 of the present invention. In the figure, a shelf portion 12 having a step portion 11 provided substantially in parallel with one end side surface 10b of a flooring material is formed on a substantially flat surface 10a of a square plate-like flooring material 10. The shelf 12 has a surface extending from the one end side surface 10b of the flooring to the stepped portion 11 in parallel with the surface 10a of the flooring, with the height of the stepped portion 11 as a step, and an opening in the one end side surface 10b inside the surface. A communication passage 15 extending from the introduction port 13 to the nozzle 14 opening in the step portion 11 in parallel with the surface in the length direction of the flooring 10 and extending almost in the width direction perpendicular to the length direction. It is formed.

In this case, for example, if the cross section of the communication path 15 is formed in a slit shape and pressurized air is supplied from the inlet 13 to the communication path 15, the pressurized air is ejected from the elongated slit-shaped nozzle 14 in the form of a jet. A plane or layered jet jet is formed along the surface 10a of the flooring 10 downstream from the portion 11 and toward the other end 10c of the flooring 10 in the length direction. By this jet jet, scattered urine falling from above toward the downstream surface 10a from the step 11 of the flooring is captured before reaching the surface, and urine droplets already attached to the surface are separated and captured. Carried to the end 10c, the floor surface 10a is cleaned.
By adjusting the pressure of the pressurized air, the jet jet flow rate was set to 150 to 200 m / sec, and a sufficient trapping result was obtained. However, the jet jet flow rate is not limited to this.

Considering that the flooring 10 is put on the surface of the user wearing footwear, the flooring 10 is made of a pressure-resistant, wear-resistant and water-resistant material such as ceramics and stainless steel, and However, it is preferable that at least the surface has water repellency or water repellency treatment, but it is of course possible to use plastic as long as these conditions are satisfied. By providing partition walls at intervals in the width direction of the floor material determined according to the thickness and strength of the floor material 10 forming the ceiling portion in the communication passage 15, the strength of the ceiling portion of the fluid passage can be increased. .

  The height of the step portion 11 is not particularly obstructive to the user's walking, and the dimension of the nozzle 14 of the communication passage 15 provided in the step portion needs to be such that an effective jet can be generated. It is desirable that the width of the slit-like nozzle 14 be maintained at about 2 mm.

  FIG. 2 shows a flooring 20 with a cleaning function having a basic configuration in Example 2 of the present invention. This embodiment is different from the first embodiment in that the surface of the shelf portion 22 that extends in parallel with the surface 20a of the flooring 20 from the top edge of the stepped portion 21 does not continue to the one end side surface 20b of the flooring 20, It is to return to the height of the surface 20a of the flooring material via a gentle slope at a relatively close position. That is, the shelf 22 is formed in a relatively narrow and long strip shape.

The communication passage 25 having the introduction port 23 opened to the one end side surface 20b of the flooring and the nozzle 24 opened in the stepped portion 21 is narrow from the inside of the surface 20a on the side of the one end side surface 20b of the flooring through the inside of the gentle slope. And the nozzle 24 of the stepped portion 21. In this case, if the introduction port 23 is positioned at a low position on the one end side surface 20b so that the communication path 25 to the gentle slope portion is slightly inclined, the degree of bending at the gentle slope portion can be reduced. It is assumed that the passage portion parallel to the floor material surface 20a up to 24 has a length sufficient to make the direction of the jet flow coming out of the nozzle 24 follow the surface 20a.

3A and 3B show a third embodiment of the present invention, in which a plurality of shelves having a surface extending from the step portion to one end side surface of the floor material in the first embodiment are provided. Here, the floor material 30 has three steps. The shelf portions 32a, 32b and 32c are formed in a stepped or terraced shape. Although each step part 31a, 31b, and 31c is provided in parallel with each other and substantially equidistantly about the one end side surface 30b of the flooring 30, it does not necessarily need to be equidistant. The point is that the length of the shelf portion downstream from each step portion is set to a length that can be covered with a sufficient flow velocity of the jet jet from the nozzle 34 of the communication passage 35. As a pressurized air source for this jet jet, for example, when using a small high-pressure centrifugal blower used in a high-speed dryer for wet hands after hand washing, the interval between the step portions is about 30 mm to about 100 mm, Desirably, about 50 mm is appropriate. Of course, this dimension setting depends on setting conditions that vary depending on how the respective fluid passages 35 of the shelves 32a-32c are configured.

The cross-sectional view of FIG. 3B shows a configuration in which the shelves 32 a-32 c are stacked in three layers, the communication passage 35 is also provided in three layers, and the inlet 33 of each layer is juxtaposed on one end side surface 30 b of the flooring 30. is there. In this case, the lowermost shelf, that is, the communication path 35 of the third shelf 32c in this case, has a length approximately three times as long as the communication path of the uppermost shelf 32a. Since the flow velocity of the pressurized air is attenuated due to the frictional resistance with the wall surface, in order to reduce this attenuation, the thickness of the communication path 35 having a slit-like cross section as the shelf portion 32 becomes lower and longer. It is conceivable to increase the number of the communication passages 35 or to shorten the length of the communication passage 35 sequentially. However, in the configuration of the present embodiment, for example, jet jets from the nozzles of the uppermost shelf 32a and the second shelf 32b flow directly above the step 31c of the lowermost shelf 32c. Therefore, a negative pressure is generated immediately after the top edge of the step portion 31c, and this negative pressure has an effect of promoting the ejection of fluid from the nozzle of the step portion 31c. This also applies to the second step 31b. In order to reduce the internal resistance of the communication path, it is possible not to divide the communication path for each layer but to make all layers into one common space, and the integrated inlet is connected to the pressurized air source in the same way To do.

In the third embodiment, an example in which the pressurized air supply device 36 is incorporated into the communication path 35 of the floor body 30 is shown. In this example, the pressurized air supply device 36 is prepared as a box-type compact device having at least the length of the one end side surface 30b of the flooring 30, that is, the same length as the width of the flooring 30. The outlet 36a is coupled to the inlet 33 of the communication passage, and is attached to the one end side surface 30b of the flooring with the upper surface flush with the surface of the uppermost shelf 32a. For example, the above-described small high-pressure centrifugal blower 37 is provided in the box-type pressurized air supply device 36, and the inside of the device is configured so that the pressurized airflow is concentrated on the jet outlet 36a. As for the power supply means to the high-pressure centrifugal blower 37, the power cord connected to this blower is pulled out to any side other than the top surface of the pressurized air supply device 36 and connected to the power socket on the wall surface of the toilet room. In general, the upper surface of the pressurized air supply device, which is part of the toilet floor, should not be obstructed or at least minimized by the user's steps. desirable. In addition, the compressed air supply device itself is separated from the floor material to be compact and installed outside, for example, directly connected to a power socket or in the vicinity thereof, and only the pressurized air supply end is installed. It can also be set as the structure couple | bonded with the one end side surface 30b of the flooring 30. FIG.

3B shows a gas-liquid separation device 30A that is provided on the other end 30c side of the flooring 30, that is, on the downstream side of the jet jet to process the jet jet. This gas-liquid separator 30A is made up of a wall body 30d standing substantially perpendicular to the jet jet, and this wall body 30d defines an attenuation space 30e in the upper part and a drain outlet connected to the drainage facility of the flush toilet in the lower part. 30f. The gas component of the jet jet colliding with the wall body 30d turns upward and the flow velocity is attenuated in the attenuation space 30e, and the liquid component is directed downward, so that it is guided to the drain port 30f. The attenuation space 30e has a volume sufficient to attenuate the flow velocity of the air flow rising along the wall 30d. However, when spatially restricted, the gas component does not already contain urine, and is released to the outside air. But it doesn't pollute the outside air.

  3A and 3B, a jet jet that cleans the surface of the uppermost shelf 32a of the flooring 30 does not occur. Therefore, the jet outlet 36a of the pressurized air supply device 36 is provided approximately one step larger than the shelf portion 32 of the flooring 30, and the surface of the uppermost shelf portion 32a is cleaned by the enlarged jet port 36a. You can also For this reason, the height of the pressurized air supply device 36 or the mounting position on the flooring 30 can be increased by one shelf, but the degree of obstacles to this increased one-step user step is large. Projecting a part or a part of a plurality of parts from the upper surface of the pressurized air supply device 36 with a curved surface, or generating a jet jet from these projections to the surface of the uppermost shelf 32a, It is preferable to minimize the degree of failure.

  In this case, the pressurized air supply device 36 also has an air intake hole 38 on the upper surface thereof, and supplies air to the high-pressure centrifugal blower 37. Further, a human body sensor 39 using, for example, an infrared sensor is provided on the upper surface, and connected to the high-pressure centrifugal blower 37 via a switch circuit (not shown) including a power switch. The switch circuit is connected to the power cord, and the human body detector 39 is always turned on. In one embodiment, when the presence of a user on the human body, that is, the floor material 30 is sensed, the power switch is turned on to The blower 37 is operated, and when the user no longer exists, the power switch is turned off to stop the blowing. That is, while the user is on the flooring 30, a jet jet is generated from the nozzle 34 of the flooring 30.

In another embodiment, the power switch is turned on when the user senses that he / she has left the flooring 30 after sensing the presence of the user, and the high-pressure centrifugal blower 37 is operated for a certain period of time. A jet jet is generated for a predetermined time after the no longer exists. Further, as another aspect, a washing water jet nozzle is formed in a part of the nozzle 34 or in combination with the nozzle 34, and a part of the introduction port 33 leading to the washing water jet nozzle and a part of the communication path 35 are formed. If a connected washing water jet generation source is provided and the washing water jet generation source is operated only for a predetermined time after the user has been absent before the high-pressure centrifugal blower 37 is operated for a certain period of time by a switch circuit, Surface washing with water and high-speed wiping and drying can be performed.

  FIG. 3B shows an alternate long and short dash line connecting the top edges of the respective step portions 31 a to 31 c constituting the plurality of shelf portions 32. This alternate long and short dash line is an oblique line that gradually descends from the uppermost shelf to the lowermost shelf when the surface of the shelf 32 is leveled. As described above, when the height of the step portion is 3 mm and the interval between the step portions is 30 mm, this oblique line is an imaginary line that forms an angle of about 6 degrees with respect to the surface of the shelf portion. Although the slope does not exist, for example, when the flooring 30 with these steps and the number of steps of 10 is installed on the front surface of the urinal, there is a clear difference in height between the uppermost stage and the lowermost stage. Even if healthy individuals do not feel any anxiety at this level, they can be a problem for the elderly and those who have trouble with the balance organs. In consideration of this, and considering the effective cleaning distance of the jet jet, the step height is kept as it is, the step interval is in the range of 50 mm to 100 mm, and the oblique line angle is about 3.5 degrees to about 2 degrees. Is appropriate. Conversely, it is also possible to configure the shelf surface to be inclined at these angles so that the one-dot chain line between the top edges of the step portions is horizontal.

  In that sense, the flooring 20 provided with the narrow shelf portion 22 in the second embodiment is advantageous in that the upstream side and the downstream side of the shelf portion 22 are the same horizontal plane with no difference in height. This point does not change even if a large number of narrow shelves 22 are installed in parallel at intervals, but in this case, the jet jet from the upstream shelves becomes obliquely upward due to the gentle slope of the downstream shelves. The jet jet from the downstream shelf does not merge smoothly. A fourth embodiment in consideration of this point is shown in FIG. However, an obliquely upward jet is not absolutely necessary, and in the case of an embodiment in which a jet jet is generated during use of a toilet, the urine droplet is trapped in the air by the obliquely upward jet before reaching the surface of the flooring. In addition, since there is an effect that the merging with the jet jet flowing along the floor material surface becomes smooth, it is also useful to positively generate an oblique upward jet as described later.

  In FIG. 4 showing Embodiment 4 of the present invention, the rectangular flooring 40 has a generally flat surface 40a, and a plurality of rows of narrow shelves 42a, 42b, 42c... They are provided at equal intervals in parallel. The narrow shelves in each row are divided into a plurality of sorting shelves 42a1, 42a2, 42a3 ...; 42b1, 42b2, 42b3 ...; ... at equal intervals in the length direction, and the sorting shelves in each row are also adjacent columns. It arrange | positions so that it may alternate with each division | segmentation shelf part. That is, for example, the jet jet from the nozzles 44 of the first row of the sorting shelves 42a1 passes through the space between the second row of the sorting shelves 42b1 and 42b2, and reaches the gentle slope of the third row of the sorting shelves 42c1. It reaches. Therefore, when the narrow shelves are juxtaposed with each other for a long time, the fluid jets immediately collide with the gentle slopes of the adjacent narrow shelves at once, and go diagonally upward at the same time. Since the effect of increasing the thickness of the layer increases, the rate of catching scattered urine droplets in the air increases, so a high effect can be expected in a mode that operates relatively during use, but as shown in FIG. When the shelves are dispersed alternately, the layer thickness of the jet jet is increased and the straightness of the jet is strongly maintained, so that the fourth embodiment operates after using the toilet and after use. It can be applied to both aspects.

  In any of the above-described embodiments, the communication path has been described as having a slit-like cross section from the inlet to the outlet, that is, the nozzle, that is, a thin hollow cavity. And is selected as the optimum passage cross-sectional shape through which fluid, ie air or water, can pass. Therefore, the width of the communication passage, that is, the dimension in the length direction of the step perpendicular to the flow direction of the pressurized air is not limited or limited, but the shelf or floor material surface that defines the fluid passage has a user's surface. Since the load is repeatedly applied, in order to maintain the strength of the shelf or the surface of the floor material according to the material constituting the floor material, a partition plate that partitions the communication path at an appropriate interval in the width direction may be provided.

If the strength is emphasized, the cross-sectional shape of the communication passage is not limited to the slit shape, and at least the nozzle part can be a circular or square cross-sectional pore, and the entire passage is arranged in parallel. It can also be formed by a large number of pores. From the viewpoint of structural or manufacturing simplicity when using parallel pores, a corrugated structure in which corrugated plates are sandwiched between two flat plates may be used.

  Further, in Example 1 and Example 3, since the jet jet flowing from the nozzle of the shelf part is substantially linearly along the flooring or the surface of the next stage shelf part, in order to direct a part obliquely upward, For example, it is also possible to make the slit-shaped cross-section or fine pore-shaped nozzles partially obliquely upward, or make a part of the double structure and the upper nozzles obliquely upward.

  In Example 5 of the present invention shown in FIG. 5A, a pressurized air supply device 56 is attached to one side surface 50b in the longitudinal direction of a substantially rectangular flooring 50, and the gas-liquid separation shown in a sectional view in FIG. 5B on the other end 50c side. While the apparatus 60 is attached, a seat-type western flush toilet 70 is installed along the longitudinal center line of the flooring 50. As the flooring material, any of those shown in any of the first to fourth embodiments may be used, but here, the flooring material of the third embodiment is used as an example.

  Accordingly, the surface 50a of the flooring 50 is formed in a multistage shape substantially the same as the flooring 30 shown in the third embodiment, and is partitioned by a plurality of stepped portions 51a, 51b... 51n parallel to the one end side surface 50b of the flooring. The shelf portions 52a, 52b,... 52n are arranged with the height gradually reduced toward the other end 50c of the flooring. In the case shown in the figure, the pressurized air supply device 56 having substantially the same configuration as that of the third embodiment and the first to third shelves 52a to 52c that follow the compressed air supply device 56 are arranged on the front side of the flush toilet 70. A located front floor portion is configured. Since the center portion of the step portion 51c of the third shelf portion 52c contacts the front end side wall 72 of the flush toilet 70, the step portion 51c does not need to be provided with a nozzle at the center contact portion. Takes measures to distribute the jets to both sides of the toilet as needed.

  The floors on both sides of the flush toilet 70 are connected to the downstream end of the front floor surface part, here the step part 51c of the third shelf part 52c, from the fourth shelf part 52d forming a pair of side floor surface parts. It is formed by n shelves 52n. From the first shelf 52a on the front floor surface portion to the n-th shelf portion 52n on the side floor surface portion, the height is sequentially reduced in a multistage manner, and the floor material downstream of the step portion 51n of the n-th shelf portion 52n. Needless to say, the surface 50a is at the bottom. At this time, the position of the last step 51n is positioned behind the toilet seat 71 in order to cover a region where water drops and scattered urine drops that fly outside the toilet bowl 70 beyond the edge of the toilet seat 71 are scattered and dropped. It is appropriate to use the vicinity of the end.

  A rectangular box-shaped gas-liquid separation device 60 having one side open is connected to the other end 50c of the floor 50 that forms the downstream end of the both-side floor surface portion that terminates at the back of the flush toilet 70. . As seen in the partial cross-sectional view of FIG. 5B, the gas-liquid separation device 60 includes a wall body 61 that stands upright at the tip of the other end 50 c of the flooring 50, a top portion 62 that is folded back from the top of the wall body, A damping space 60a is defined by an upper wall portion 63 having a lower end 63a that hangs down from the front end of the top portion and is located on the upper side of the jet jet, and receives the entire width of the jet jet between the lower end 63a of the upper wall portion and the floor surface 50a. An opening 60b is provided. A bottom portion 64 having a concave surface at a portion facing the attenuation space 60a of the other end 50c of the flooring, and a drain port 65 provided at the lowest position of the bottom portion 64 and connected to a drain pipe (not shown) of the flush toilet 70 are provided. Provide.

  Jet jets from the nozzles of the step portions 51a to 51n on the front floor portion and the side floor portions are captured after wiping and cleaning the surfaces of the shelves 52b to 52n or the floor material surface 50a downstream thereof. The gas component of the jet jet that enters the gas-liquid separation device 60 together with the urine droplets from the opening 60a (solid arrow and broken line arrow in FIG. 5B) and collides with the wall 61 changes the flow direction upward, and the flow velocity is increased in the attenuation space 60a. Attenuated and the urine droplets, which are liquid components, flow downward and reach the drain port 65. In other words, the jet jet is not dissipated as it is, but is separated into gas and liquid by the gas-liquid separator 60 and processed.

  In the above embodiment, the gas-liquid separation device 60 does not adopt a configuration in which a flush flow is supplied to the surface of the wall body 61. However, even if a small amount of liquid, that is, urine after separation, may adhere to the inner surface of the bottom 63. Therefore, there may be provided means for supplying a small amount of water washing to wash away this small amount of urine at least immediately after the stop of the cleaning by the jet jet. Alternatively, water can be flowed first as a jet jet and then air.

  On the other hand, the separated gas is attenuated and extinguished in the attenuation space 60a. However, if it is difficult to secure a space having a sufficient volume for attenuation, a release port 66 is provided in the top portion 62 to attenuate in the possible space. After letting it open, it may be opened to the open air. Even in this case, since the urine is separated, there is no contamination to the outside air.

  In the fifth embodiment, the combination of the Western-style seat-type flush toilet 70 shown in FIG. 5A, the flooring 50 with a cleaning function and the gas-liquid separator 60 according to the present invention is shown, but the flush toilet of this embodiment It is possible to replace 70 with a flush toilet 70A with a Japanese style floor as shown in FIG. 5C. The flooring 50A, the pressurized air supply device 56A, and the gas-liquid separation device 60A can use the configurations of the flooring 50, the pressurized air supply device 56, and the gas-liquid separation device 60 described with reference to FIGS. 5A and 5B as they are. However, although the front floor portion for the Japanese style flush toilet 70A of FIG. 5C is shown as a shelf 52Aa and 52Ab having stepped portions 51Aa and 51Ab, in the case of a Japanese style toilet, Since both feet are placed on the side of the toilet bowl, it is necessary to change the length of the side floor portion including the shelf portions 52Ac to 52An having the step portions 51Ac to 51An and shorten the front floor portion.

  Example 6 shown in FIGS. 6A and 6B shows a combination of a flooring with a cleaning function and a standing flush toilet according to the present invention. As shown in FIG. 6A, a floor body 80 including a step portion made of a multi-stage floor material substantially as shown in the third embodiment includes a receiving surface portion 92 that is erected and receives a user's urination, and a sink that forms the lower portion thereof. It is formed integrally with the main body 90 of the flush toilet including the portion 96. Of course, in this case, instead of completely integrating the floor body 80 and the main body 90 from the beginning of the manufacturing process, for example, the sink portion 96 of the main body 90 and the floor body 80 are separated so as to be connectable, Needless to say, it may be assembled and connected at the time of installation.

  The floor body 80 includes substantially the same configuration as the floor material 30 of the third embodiment, including the pressurized air supply device 85 provided at one end of the floor body 80 farthest from the sink portion 96. It goes without saying that any of the flooring materials in the embodiment can be adopted. However, here, when the drooping receiving portion 96a of the sink portion 95 protruding between both feet of the user standing on the step portion in front of the receiving surface portion 92 of the main body 90 is protruded relatively long, the embodiment of FIG. It is preferable to employ an arrangement similar to that of the side floor surface portion 5. In FIG. 6A, therefore, the most downstream shelf 82n is shown separately on both sides of the droop receiving portion 96a, but includes the most upstream shelf 82a and constitutes the majority of the step portion where the user stands. If the jet flow from the stepped portion upstream of the portion 96a, for example, the nozzles 81a and 81b, has a flow velocity and flow rate sufficient to clean the floor surface on both sides of the receiving portion 96a, shelves on both sides Part, here 82n and its step part 81n may be omitted. As shown in FIGS. 6A and 6B, the rising upper edge portion of the drooping receiving portion 96a is equal to or less than the height of the most downstream position of the floor body 80, that is, the step portion, so that there is no jet jet flowing from the floor body surface. The upper layer of the sink part 96 is reached without obstruction by the drooping part. In other words, since the urine droplets dropped and adhered to the most downstream position of the step portion, that is, the position adjacent to the sink portion 96 are captured by the jet jet and carried to the upper layer of the sink portion, the drooping receiving portion 96a protruding to the step portion is It is not necessary to provide it.

  The gas-liquid separation device 90a according to the sixth embodiment is provided at a central lower portion of the receiving surface portion 92 of the main body 90, and has a configuration shown in the partial cross-sectional view of FIG. 6B. The receiving surface portion 92 is provided with an attenuation space 95 between the downward front wall 93 and the rear peripheral wall 94 constituting the wall body at the center lower end portion from the center facing both sides to the user standing on the step portion. Formed in a double structure. The downward front wall 93 that forms the lower end of the receiving surface portion has a lower end 93a that is spaced from the bottom surface of the sink portion 96 and is at a height that is substantially the upper surface of the jet jet that passes from the step portion surface to the sink portion. The attenuation space 95 has a sufficient volume by being continuous with a large space between the rectangular back wall surface of the main body 90 and the semicircular back wall surface of the receiving surface portion 92, for example. A jet jet containing a liquid component consisting of scattered urine separated from the surface of the step portion by the jet jets from the shelf portions 82a to 82n forming the step portion or collided with the rear peripheral wall 94 forming an orthogonal wall body. The gas component is guided to the upper attenuation space 95, and the liquid component is guided to the drainage port 97 of the sink part 96. In this case, the flush flow that exits from the water supply unit 91 at the top of the main body 90 and cleans the surface of the receiving surface unit 92 and the surface of the downward front wall 93 continuous thereto is supplied after the completion of the cleaning of the step unit by, for example, a jet jet. . Of course, this order may be reversed, but it is preferable that the washing flow to the receiving surface and the jet jet to the step are generated separately.

Moreover, since the description about the structure and operation | movement of Example 3 by FIG. 3 can be applied about the structure and operation | movement of the pressurized air supply apparatus 85 in Example 6, detailed description is abbreviate | omitted here.

  Example 7 of the present invention shown in FIGS. 7A and 7B is a combination assembly of a floor body using a flooring with a cleaning function according to the present invention and a plurality of flush toilet bowls installed side by side. The figure shows three urinals juxtaposed, and an assembly in which three sinks and floors are integrated, but it is also possible to make an assembly of three or less or three or more. is there. Moreover, although the thing of Example 3 shown in FIG. 3 is shown as an example as a flooring, it cannot be overemphasized that any of other Examples may be used.

  The floor body made of the flooring material 100 having the same configuration as that of the third embodiment has shelf sections 102a to 102n each having step sections 101a to 101n each having slit-like nozzles opened toward the urinal body 110 in a multistage manner. It is arranged and has a width corresponding to the three receiving surface portions 112a to 112c of the urinal body 110 that are placed side by side with the common water supply device 111 placed on the head. The pressurized air supply device 103 connected to the shelf 102a on the one end side on the most upstream side of the floor body has the same width as the three floor bodies, and the internal configuration of the floor body and the pressurized air supply device 103 is as follows. Although it is advantageous in terms of cost to form one unit common to the three units, it is of course possible to configure each unit separately. The floor body may have a common configuration, and the pressurized air supply device may have an individual configuration. As the jet jet generation operation in the case where both are configured in common, instead of the automatic operation by the human body sensor described in the third embodiment, it is possible to perform the intermittent operation at regular time intervals. These configurations and modes of operation are similarly applied to the flush flow supply operation of the water supply device 111 with respect to the receiving surface portion 112 of the main body 110.

  Similarly to the case of the sixth embodiment, the floor body is provided integrally or so as to be integrally connectable to the sink portion 116 provided in the lower portion of the urinal body 110. In the case of the multiple juxtaposition type as shown in FIG. 7A, the drooping receiving portion is not configured to protrude toward the user's step position for each of the receiving surface portions 112a to 112c, and the floor body side front end edge of the sink portion 116 is entirely sinked. It is advantageous to locate the step portion side over the width of the portion, that is, to increase the depth dimension of the sink portion. Therefore, in order for the user to stand as close as possible to the receiving surface portion 112, the user stands near the sink portion, that is, near the leading edge of the floor body. It is advantageous to arrange the as close to the sink as possible.

  The jet jet jetted from the nozzles of the respective step portions 101a to 101n of the floor body to clean the surface of the floor body blows through the upper layer of the sink portion 116 and is provided at the lower portion of the receiving surface portion 112 of the urinal body 110. The gas reaches the apparatus 110a, and the gas component is guided upward to be attenuated, and the liquid component is guided downward to be drained. The gas-liquid separation device 110a includes a lower end 113 of the receiving surface portion 112 that is spaced apart from the bottom surface of the sink portion 116 and terminates at a substantially upper position of the jet jet, a rear peripheral wall 114 that rises from the bottom surface at a position retracted from the lower end 113, An attenuation space 115 is provided between the lower end portion of the receiving surface portion and the rear peripheral wall 114. In this case, the attenuation space 115 can obtain a sufficient volume by, for example, raising the rear peripheral wall 114 to the head of the receiving surface portion 112 and making the back portion a complete double structure. However, as shown in FIG. After securing a certain length of the peripheral wall 114 with the back surface of the receiving surface part, the attenuation space 115 is opened upward, and a space between the back surface of the receiving surface part and the wall surface of the toilet room where the assembly is installed is used. You can also In this case, since a small amount of urine contained in the jet jet is separated, it does not cause a bad odor in the toilet room.
