Description

  The present invention relates to a urinal unit, and specifically to a urinal unit including a sensor for detecting a human body or the like.

When a human body or urine flow is accurately detected by a Doppler frequency signal from a microwave sensor and the opening / closing of the valve is controlled with good timing, a urinal apparatus that can use washing water without waste becomes possible. That is, since it is non-contact, it is hygienic, and a high cleaning effect can be obtained by flowing only a predetermined amount of water at an optimal timing, and a water saving effect can also be obtained. There is a technical disclosure example regarding a urinal washing device that controls opening and closing of a valve provided in a flush water pipe of a urinal (Patent Document 1). In this example of technical disclosure, the valve is controlled by calculating the liquid flow state of the ball space based on the Doppler frequency signal that is the difference between the transmitted wave and the received wave.
Japanese Patent No. 3740696

When the sensor is built in the upper part of the urinal, the portion projects to the front, so there is room for improvement in terms of usability and aesthetics. On the other hand, when the sensor is provided behind the urinal, the overhang of the upper part of the urinal can be suppressed, and the usability is improved and the appearance is neat.
However, when the sensor is attached to the back of the urinal, desired detection characteristics may not be obtained if the detection range changes due to a shift in the sensor attachment position or angle. On the other hand, when installing a urinal when newly installing or remodeling a toilet, if a fine adjustment is required regarding the sensor mounting position at the construction site, there is a problem that the construction is difficult.

  The present invention has been made based on recognition of such a problem, and provides a urinal unit capable of reliably and easily mounting a sensor at a predetermined position behind the urinal.

  According to one aspect of the present invention, a vertical frame standing substantially vertically, a front plate provided on the front surface of the vertical frame, a urinal provided on the front surface of the front plate, and a back for attaching the urinal A hanger and a microwave sensor provided behind the urinal, wherein both the back hanger and the microwave sensor are fixed to the vertical frame via an attachment member. A urinal unit is provided.

  ADVANTAGE OF THE INVENTION According to this invention, the urinal unit which can attach a sensor reliably and easily to the predetermined position behind a urinal is provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component.

FIG. 2 is a schematic diagram showing the internal structure of the urinal unit.
FIG. 3 is a cross-sectional view of the urinal unit.

A lining unit 100 is installed on the wall surface 900 of the toilet room illustrated in FIG. 1, and a urinal 200 and a handrail 300 are attached to the front surface of the lining unit 100. The urinal 200 has a spreader 280 above the bowl, and can be washed with water by discharging washing water therefrom.
The lining unit 100 is connected to a water supply pipe for supplying cleaning water to the urinal 200, a drain pipe 140 (see FIG. 3) for discharging waste water from the urinal 200, and a solenoid valve and a human body detection sensor. For this purpose, electrical wiring for the odor, a deodorizing tube for sucking odor, a microwave sensor 400 (see FIGS. 2 and 3), and the like are appropriately accommodated. The front plate 110 of the lining unit 100 projects beyond the wall surface 900 of the toilet room in order to accommodate these elements. That is, the wall surface 900 of the toilet room is set back by the depth of the upper surface plate 120 of the lining unit 100.

The lining unit 100 includes a plurality of vertical frames 150 erected substantially perpendicular to the floor surface of the toilet room, and a horizontal frame 152 that extends substantially perpendicular to the vertical frames 150 and appropriately connects the vertical frames 150. And having. A front plate 110 is fixed to the front surface of the vertical frame 150. A back hanger 170 is provided on the front plate 110 of the lining unit 100, and the urinal 200 is fixed to the front plate 110 of the lining unit 100 by being hooked on the back hanger 170.
FIG. 2 is a schematic view of the front plate 110 removed from the lining unit 100 and viewed from the front side (the urinal 200 side), and shows that the attachment member 160 is fixed between a pair of vertical frames 150. Has been.

FIG. 4 is a partially enlarged view of FIG.
5A is a front view of the mounting member 160, and FIG. 5B is a cross-sectional view taken along line AA in FIG. 5A.
FIG. 6 is a schematic diagram showing the back hanger 170. 6A is a front view of the back hanger 170, FIG. 6B is a top view, and FIG. 6C is a side view.

  FIG. 7 is a schematic cross-sectional view of a mounting portion for the back hanger 170 and the microwave sensor 400 in the present embodiment.

  The attachment member 160 in this embodiment is formed by processing a metal plate. At both ends of the mounting member 160, mounting holes 168 (see FIG. 5A) for fixing to the vertical frame 150 with screws or the like are provided. Further, in the center of the attachment member 160, a notch 162 for allowing a water supply pipe (not shown) to the spreader 280 of the urinal 200 and the microwave sensor 400 to pass therethrough is provided. An attachment hole 166 for attaching the microwave sensor 400 with a screw or the like is provided below the notch 162. In addition, attachment holes 164 for fixing the back hanger 170 are provided on the left and right sides of the notch 162.

  The back hanger 170 includes a mounting portion 171 having a hooking portion 172 that protrudes vertically upward from the plate surface of the front plate 110 of the lining unit 100, and a rear surface side (that is, toward the inside of the lining unit 100) from the mounting portion 171. And a nut 176 screwed into the screw 174.

  The front plate 110 of the lining unit 100 is provided with an opening 112 (see FIG. 4). The attachment portion 171 of the back hanger 170 is supported by the front surface of the front plate 110 of the lining unit 100. Then, the screw 174 of the back hanger 170 passes through the opening 112 (see FIG. 4) of the front plate 110 and the mounting hole 164 (see FIG. 5) of the mounting member 160, and the nut 176 is screwed from the back side of the mounting member 160. Is fixed. That is, the back hanger 170 is fixed by the mounting member 160 while being supported by the front plate 110 of the lining unit 100. Thus, by fixing the back hanger 170, the mounting position of the urinal 200 is also uniquely determined. That is, the mounting position of the urinal 200 is determined by the mounting member 160.

  On the other hand, the microwave sensor 400 is inserted into a sensor holder 410 fixed to the attachment member 160 and fixed. Therefore, the sensor holder 410 is fixed by screwing a screw 412 or the like into the mounting hole 166 (see FIG. 5) of the mounting member 160. When inserted in the sensor holder 410, the microwave sensor 400 passes through the opening 112 provided in the front plate 110 of the lining unit 100 and faces a position close to the back surface of the urinal 200. The front plate 110 is formed of, for example, a PVC steel plate, and the like. By making the microwave sensor 400 project through the opening 112 through the opening 112 in this manner, the front plate 110 is generated from a radio wave radiated from the microwave sensor 400 or a human body. Can be prevented from being shielded by the front plate 110.

  A protrusion is provided on the inner side of the sensor holder 410, and when the microwave sensor 400 is inserted into the sensor holder 410, the protrusion of the sensor holder 410 engages with a recess provided in the microwave sensor 400. The microwave sensor 400 is fixed. When removing the microwave sensor 400, the microwave sensor 400 is pulled backward to disengage from the sensor holder 410, and the microwave sensor 400 can be pulled out of the sensor holder 410. In this way, the attachment is easy, the attachment position can always be reliably defined, and the microwave sensor 400 can be easily removed during inspection and repair.

As described above, in this embodiment, the back hanger 170 and the microwave sensor 400 are both fixed relative to the vertical frame 150.
Specifically, the microwave sensor 400 is inserted and fixed in a sensor holder 410 fixed to the attachment member 160. That is, the attachment position of the microwave sensor 400 is uniquely determined by the attachment member 160. As described above, the attachment position of the back hanger 170 is determined by the attachment member 160, and at the same time, the attachment position of the microwave sensor 400 is also determined by the attachment member 160, so that the urinal 200 and the microwave sensor 400 are relative to each other. A simple positional relationship can be determined uniquely. That is, in the construction of the site where the urinal unit is installed in the toilet room, the positional relationship between the urinal 200 and the microwave sensor 400 is not required to be adjusted, and the predetermined positional relationship can always be realized reliably and easily. it can. As a result, stable detection characteristics can be obtained with good reproducibility, and the advantages of using the microwave sensor 400 can always be maximized.

FIG. 8 is a schematic view illustrating the detection range of the microwave sensor 400 in the urinal unit of this embodiment.
FIG. 9 is a schematic view illustrating the detection range of the microwave sensor in the urinal unit according to the first comparative example.

  First, the comparative example shown in FIG. 9 will be described. The microwave sensor 400 is provided on the back surface of the urinal 200 so as to face in a substantially horizontal direction. That is, the radio wave beam 480 radiated from the microwave sensor 400 passes through the bowl of the urinal 200 and propagates in a substantially horizontal direction. In this case, if the mounting position of the microwave sensor 400 is set slightly lower, both when the user 800 is an adult (FIG. 9A) and when it is a child (FIG. 9B). Detection is possible. However, it may be difficult to detect the urine flow 820 of the user 800. That is, in the specific example shown in FIG. 9B, when the user 800 is a child, the urine flow 820 may be out of the range of the radio wave beam 480.

  If the urine flow 820 of the user 800 can be detected, for example, the amount of urine can be estimated, and the amount of washing water flowing from the spreader 280 can be adjusted accordingly. Specifically, the amount of washing water can be increased when the amount of urine is large, and the amount of washing water can be reduced when the amount of urine is small. If it does in this way, the usage-amount of washing water will be suppressed and the water-saving effect will be acquired, maintaining a washing effect.

  However, in the case of the comparative example shown in FIG. 9, it may be difficult to detect the urine flow 820 of the user 800, as illustrated in FIG. 9B. Still further, in order to detect the urine flow 820 by the Doppler effect, it is desirable that the flow direction of the urine flow 820 is close to perpendicular to the propagation direction of the radio wave beam 480. This is because the Doppler effect is most prominent even when the moving body approaches or moves away along the propagation direction of the radio wave beam 480. On the other hand, in the case of the comparative example shown in FIG. 9, the flow direction of the urine flow 820 is a direction that is nearly perpendicular to the propagation direction of the radio beam 480. In other words, the moving direction of the moving body is substantially perpendicular to the propagation direction of the radio wave beam 480, and the Doppler effect is hardly exhibited. From this viewpoint, there is room for improvement in the comparative example shown in FIG.

  On the other hand, in the present embodiment, as shown in FIG. 8, the radio wave beam 480 is radiated from the upper rear side of the urinal 200 toward the oblique lower side. In this way, the user 800 can be reliably detected whether the user 800 is an adult (FIG. 8A) or a child (FIG. 8B). In any of these cases, the urine flow 820 of the user 800 is also within the propagation range of the radio wave beam 480. In any of these cases, the flow direction of the urine flow 820 is almost parallel to the propagation direction of the radio wave beam 480. That is, it becomes easy to detect the urine flow 820 by the Doppler effect, and it is possible to control the amount of washing water according to the amount of urine.

FIG. 10 is a schematic diagram illustrating a second comparative example.
That is, in the present comparative example, the microwave sensor 400 is attached to the urinal 200 in the same arrangement relationship as that of the present embodiment described above with reference to FIGS. That is, the mounting bracket 430 is fixed behind the spreader 280 of the urinal 200, and the sensor holder 410 is fixed to the mounting bracket 430. A microwave sensor 400 (not shown) is inserted into the sensor holder 410 and fixed.

  FIG. 10 shows a state in which the urinal 200 of such a comparative example is packed. In this modified example, the sensor holder 410 protrudes and is fixed to the back surface side of the urinal 200, so that the sensor holder 410 is likely to be deformed or damaged when it comes into contact with the packaging basket 700 or the like. For this reason, when the urinal 200 is shipped from the factory, the urinal 200 needs to be accommodated in the packaging basket 700, and at this time, it is necessary to provide the raised cushioning material 710 for protection. However, even in this case, after the urinal 200 is taken out from the packaging basket 700, the sensor holder 410 protruding to the back side is brought into contact with the lining unit 100 or the like in the construction process to be installed on the site, and deformation or breakage occurs. There can be. If the sensor holder 410 is deformed or damaged, the microwave sensor 400 cannot be inserted, or the direction of the microwave sensor 400 changes, and predetermined detection characteristics cannot be obtained.

  In contrast, according to the embodiment described above with reference to FIGS. 1 to 8, the sensor holder 410 is not fixed to the urinal 200 but fixed to the attachment member 160. On the other hand, the positional relationship between the urinal 200 and the microwave sensor 400 can be uniquely determined by fixing the back hanger 170 to the attachment member 160. The microwave sensor 400 can always be attached in a predetermined direction without fear of deformation or breakage of the sensor holder 410 during construction on site. As a result, stable detection characteristics can be obtained with good reproducibility, and the advantages of using the microwave sensor 400 can always be maximized.

FIG. 11 is a schematic diagram illustrating a third comparative example.
In this comparative example, the microwave sensor 400 is built in the upper part of the urinal 200. The radio wave beam 480 emitted from the microwave sensor 400 propagates obliquely downward. In the case of this comparative example, it is possible to detect the user 800 and its urine flow 820 relatively stably as in the embodiment described above with reference to FIG.

However, in order to incorporate the microwave sensor 400 in the upper part of the urinal 200, it is necessary to project the upper part of the urinal 200 to the near side when viewed from the user 800. However, if the upper part of the urinal 200 is projected to the front side, the user 800 will not easily see his / her hand.
FIG. 12A is a schematic view of the urinal 200 of this embodiment as viewed from above, and FIG. 12B is a schematic view of the urinal 200 of the third comparative example as viewed from above.
In the case of the third comparative example, as illustrated in FIG. 12B, the upper surface 240 of the urinal 200 may extend to the near side as viewed from the user, and may block the user's line of sight. That is, the upper surface 240 of the urinal 200 extends just below the eyes of the user 800, and it is not easy for the user 800 to see not only the bowl surface 230 but also his / her hand.

  On the other hand, according to the present embodiment, as shown in FIG. 12A, the upper surface 240 of the urinal 200 is retracted in the direction of the front plate 110 of the lining unit 100, so However, almost the entire bowl surface 230 can be seen. As can be seen from FIG. 9, the user 800 can see almost the entire bowl surface 230. As a result, the user 800 is given a sense of openness and can confirm the urine color and state reliably and easily while confirming the hand.

  When the upper surface of the urinal 200 is retracted, it is difficult to incorporate a conventional infrared sensor in the upper part of the urinal 200. In contrast, in the present embodiment, the microwave sensor 400 is provided in the lining unit 100 on the back side of the urinal 200. Since the microwaves pass through the pottery, they can be placed behind the urinal 200. In this way, in the urinal 200 in which the upper surface 240 of the urinal 200 is remarkably retracted and the bowl surface is opened obliquely upward, it is possible to detect the human body and the urine flow and to flow the washing water automatically.

  FIG. 13 is a three-side view illustrating the urinal 200 and the handrail 300 according to this embodiment.

  The urinal 200 of the present embodiment has a bowl surface 230 that opens obliquely upward. That is, the lower end 220 of the bowl opening of the urinal 200 is on the near side as viewed from the user (in the direction of the arrow A), while the upper end 210 of the bowl opening is rearward (in the direction opposite to the arrow A) as viewed from the user. Retreating. As a result, the depth of the upper surface 240 of the urinal 200 (the length in the direction of arrow A) is the depth of the urinal 200 (the length from the front plate 110 of the lining unit 100 to the lower end 220 of the bowl opening of the urinal 200). Is significantly smaller than As a result, as will be described in detail later, when the urinal 200 is viewed from above, almost the entire bowl surface 230 can be seen.

  In this way, when the bowl surface 230 of the urinal 200 is opened obliquely upward, the user is given a feeling of opening, and the design is good and clean. Furthermore, the feeling of pressure given to the user can be greatly reduced. That is, the user can approach the urinal 200 more easily than in the past. As a result, the urine can be reliably dropped on the bowl surface 230, and the urine is prevented from dropping on the floor surface in front of the urinal 200. In other words, the toilet room having a clean design and good appearance is used more cleanly, so that a superimposed effect of giving a comfortable feeling to the user can be obtained.

  Moreover, by cleaning the upper surface 240 of the urinal 200 and opening the bowl surface 230, cleaning becomes easy, and as a result, a more clean state can be maintained. That is, the clean urinal 200 with less scale and dirt can be maintained.

  On the other hand, the handrail 300 of the present embodiment extends a pair of base portions 310 protruding forward (in the direction of arrow A) substantially perpendicularly to the front plate 110 of the lining unit 100 and obliquely rearward from the tips of the base portions 310. A pair of inclined portions 320 and a horizontal portion 330 extending in a substantially horizontal direction and connecting the tips of the inclined portions 320 are provided. In this specific example, the horizontal portion 330 is provided at a position retracted from the tip of the base portion 310 (the direction opposite to the arrow A). In other words, the inclined portion 320 is inclined in a direction of retreating toward the horizontal portion 330.

  In the present embodiment, the horizontal portion 330 of the handrail 300 is provided at a higher position than the upper surface 240 of the urinal 200. Furthermore, the upper surface plate 120 of the lining unit 100 is provided at a position lower than the horizontal portion 330 of the handrail 300.

By providing the horizontal portion 330 of the handrail 300 at a higher position than the upper surface 240 of the urinal 200, the user's feeling of pressure using the handrail is greatly reduced. Furthermore, by providing the upper surface plate 120 of the lining unit 100 at a position lower than the horizontal portion 330 of the handrail 300, the user is given a feeling of opening and the feeling of pressure is further reduced.
Furthermore, the slanted portion 320 of the handrail 300 has substantially the same slant as the left and right side portions 250 of the open end (rim line) of the bowl surface 230 of the urinal 200, so that a good-looking and clean appearance can be obtained. can get. That is, by surrounding the left and right sides of the urinal 200 with the inclined portion 320 that is inclined substantially parallel to the rim line of the urinal 200, a sense of security is given to the user and the user can easily approach the urinal 200.

  And according to this embodiment, the microwave sensor 400 can be reliably and easily attached behind such a urinal 200. As a result, while maintaining the clean appearance of the urinal 200, the human body and the urine flow can be reliably detected, and a sanitary urinal unit with a high water-saving effect can be realized.

The present invention is not limited to the urinal 200 described above with reference to FIGS.
FIG. 14 is a schematic diagram showing another specific example of the urinal 200 and the handrail 300 that can be used in the present invention.
In this specific example, the upper end 210 of the bowl opening of the toilet bowl 200 slightly protrudes toward the user. In the present invention, such a urinal 200 can also be used.

Next, a second embodiment of the present invention will be described.
FIG. 15: is the schematic diagram which looked at a part of urinal unit concerning the 2nd Embodiment of this invention from the front side (namely, urinal side). That is, FIG. 15 is a schematic diagram showing a portion corresponding to FIG.
FIG. 16 is a schematic cross-sectional view showing a mounting portion of the microwave sensor 400.

  In the present embodiment, the first mounting member 186 and the second mounting member 180 are fixed between the pair of vertical frames 150 on the back side of the front plate 110.

  That is, attachment holes 187 are provided at both ends of the first attachment member 186 and are fixed to the vertical frame 150 with screws or the like. Further, the second mounting member 186 is provided with a notch 188 so that a water supply pipe to the spreader 280 can be provided. The back hanger 170 is fixed to the second mounting member 186.

  On the other hand, attachment holes 182 are provided at both ends of the second attachment member 180 and are fixed to the vertical frame 150 by screws or the like. The sensor holder 410 is fixed to the first attachment member 180, and the microwave sensor 400 is inserted and fixed. In a fixed state, the microwave sensor 400 penetrates the opening 112 provided in the front plate 110 and protrudes forward like the first embodiment, and is a radio wave beam obliquely downward from behind the urinal 200. 480 is emitted.

That is, also in this embodiment, the back hanger 170 and the microwave sensor 400 are both fixed relative to the vertical frame 150.
Specifically, in the present embodiment, the mounting position of the microwave sensor 400 is determined by the second mounting member 180, and the mounting position of the urinal 200 is determined by the first mounting member 186. Therefore, by defining the positional relationship between the first mounting member 186 and the second mounting member 180, the positional relationship between the urinal 200 and the microwave sensor 400 can be uniquely defined. For this purpose, for example, it is only necessary to define the positions of the mounting holes provided in the vertical frame 150 in order to fix the first and second mounting members 186 and 180 to the vertical frame 150. In the urinal unit provided with the lining unit 100, each part is designed according to the installation site, and parts such as the vertical frame 150 and the front plate 110 are often arranged in the factory. Therefore, the positional relationship between the urinal 200 and the microwave sensor 400 is uniquely defined by previously forming mounting holes for mounting the first and second mounting members 186 and 180 in the vertical frame 150 at the factory. be able to. That is, at the construction site, the microwave sensor 400 can be attached reliably and easily only by assembling these parts in a predetermined procedure.

  On the other hand, when assembling the lining unit 100 by forming the vertical frame 150 at the construction site, for example, providing dimension data of mounting holes for mounting the first and second mounting members 186 and 180, or In addition, it is possible to provide a pattern for forming a mounting hole in the vertical frame 150. If it does in this way, a mounting hole will be formed in the suitable position of the vertical frame 150 in a construction site, and the mounting position of the microwave sensor 400 will be correctly carried out by fixing the 1st and 2nd mounting members 186 and 180. It can be reproduced.

Next, a third embodiment of the present invention will be described.
FIG. 17: is the schematic diagram which looked at a part of urinal unit concerning the 3rd Embodiment of this invention from the front side (namely, urinal side). That is, FIG. 17 is a schematic diagram showing a portion corresponding to FIG.
FIG. 18 is a schematic cross-sectional view showing a mounting portion of the microwave sensor 400.

  In the present embodiment, a first attachment member 186 is fixed between the pair of vertical frames 150 on the back side of the front plate 110. That is, the first mounting member 186 is provided with a mounting hole 187 and is fixed to the vertical frame 150 with screws or the like. Further, the first mounting member 186 is provided with a notch 188 so that a water supply pipe to the spreader 280 can be provided. Furthermore, the back hanger 170 is fixed to the first attachment member 186.

  In the present embodiment, the second mounting member 190 is fixed to the first mounting member 186. The second attachment member 190 is a substantially U-shaped plate-like body, and attachment holes are formed at both ends thereof. The mounting hole is penetrated by the screw 174 of the back hanger 170 together with the first mounting member 186 and is tightened by the nut 176. That is, the second attachment member 190 is fixed to the first attachment member 186 together with the back hanger 170. The vicinity of the center of the second mounting member 190 extends below the opening 112 of the front plate 110 so as to avoid the piping of the spreader 280 of the urinal 200. The sensor holder 410 is fixed near the center of the second mounting member 190, and the microwave sensor 400 is inserted and fixed.

As described above, also in this embodiment, the back hanger 170 and the microwave sensor 400 are both fixed relative to the vertical frame 150.
Specifically, in this embodiment, both the back hanger 170 and the microwave sensor 400 are fixed to the first mounting member 186. That is, the positional relationship between the urinal 200 and the microwave sensor 400 is uniquely determined. Therefore, in the construction site, the microwave sensor 400 can be attached reliably and easily only by assembling these parts in a predetermined procedure.

  In the specific examples shown in FIGS. 17 and 18, the second mounting member 190 is fixed at the mounting portion of the back hanger 170 of the first mounting member 186, but the present invention is not limited to this.
