A waste water valve device that operates according to the waste water, the waste water valve device has a spring made of a shape memory material in contact with the water of the waste water flow path, and a valve body that is moved by the spring, When the temperature of water in contact with the spring is lower than the transformation temperature of the shape memory material, the spring is in a contracted state, the valve body takes a discarded water discharge position, and the temperature of water in contact with the spring is the transformation temperature. When the temperature is higher than the above, in the warm water washing apparatus in which the valve body takes the waste water stop position when the spring is in an extended state, the spring is disposed so as to be in contact with the water of the waste water flow path. When it becomes higher than the predetermined temperature, it will elongate and lower than the predetermined temperature. A temperature sensing element for that the Chijimitan, is characterized in that a temperature display member that moves in conjunction with extension and Chijimitan of temperature sensitive body.

  According to a second aspect of the present invention, there is provided the warm water cleaning apparatus according to the first aspect, wherein the temperature display member is disposed so as to be movable in the vertical direction in a container in which an opaque or translucent liquid is sealed, and at least one of the upper surfaces of the container. The temperature display member is provided with a temperature display color, figure, or character on the upper surface of the temperature display member. When the temperature sensing body is in a contracted state, the temperature display member is in the liquid. In the buried state, when the temperature sensing body extends, the temperature display member rises near the liquid surface of the liquid, and the upper surface of the temperature display member can be visually recognized through the transparent portion. It is.

  According to a third aspect of the present invention, there is provided the hot water cleaning apparatus according to the second aspect, wherein the temperature sensing element is a spring made of a shape memory material having a transformation temperature substantially equal to the shape memory material constituting the spring. .

  According to a fourth aspect of the present invention, there is provided a warm water cleaning apparatus according to the third aspect, wherein the waste water valve device has a substantially cylindrical shape, and is vertically movable in a valve box having a cylindrical axial direction as a vertical direction. The valve body disposed, the spring disposed on the lower side of the valve body, a cylindrical body having a lower end connected to the valve body, and an upper end protruding upward from the valve box, and the cylindrical body The container connected to the upper end of the cylindrical body, a water passage opening communicating with the inside and outside of the cylindrical body, the spring disposed inside the cylindrical body, and the upper and lower sides of the cylindrical body above and below the spring. A first magnet that is movably disposed; a magnetic body that is disposed below the spring in the cylindrical body; and that is attracted to the first magnet; and the magnetic body that is disposed in the container. A temperature display member, and at least a part of the temperature display member is the first magnet. The temperature display member is configured to rise by the repulsive force of the second magnet when the first magnet rises, and the valve box Is a large-diameter part having an inner diameter larger than the upper part, and the upper part is a small-diameter part having an inner diameter smaller than the lower part. The large-diameter part is provided with an inlet, and the small-diameter part is provided with an outlet. The valve body is positioned at the large diameter portion when the spring is in a contracted state and is opened, and is engaged with the small diameter portion when the spring is in an expanded state. It is a feature.

  A hot water cleaning device according to a fifth aspect of the present invention is the hot water cleaning device according to any one of the first to fourth aspects, wherein a diaphragm valve is provided in a waste water flow path on the upstream side of the waste water valve device. When the valve device is opened, the valve device is opened, and the water in the waste water channel is discharged to the toilet.

  In the hot water cleaning apparatus of the present invention, the shape memory material spring is disposed so as to be in contact with the water from the hot water source. When the temperature of the water from the hot water source is low, the shape memory material spring is shortened. Then, the waste water operation is performed. When the temperature of the water from the hot water source becomes high, the shape memory material spring is extended, and the discarded water operation is stopped. Further, when the temperature of the waste water is increased, the temperature sensing body is extended, and thereby the temperature display member is moved, so that the user can perceive that the temperature of the water from the hot water source is increased.

  In the present invention, since the temperature sensing element is disposed so as to come into contact with water from the hot water source, the movement of the temperature display member is quick. By using a spring made of a shape memory material such as a shape memory alloy as a temperature sensing element as described in claim 3, the movement of the temperature display member becomes sufficiently agile.

  In the present invention, since the temperature display member moves in conjunction with the expansion and contraction of the temperature sensing body, the temperature display of the hot water from the hot water source is performed, and thus this temperature display is performed without using a power source.

  As a configuration for performing the temperature display by the movement of the temperature display member, the structure of claim 2 is preferable. According to this configuration, when the temperature of the hot water from the hot water source is low, the temperature sensing body is in a contracted state, the temperature display member in the container is submerged in an opaque or translucent liquid, and the display (color , Graphics or characters) are not visible. When the temperature of the hot water from the hot water source is high, the temperature sensing body expands, the temperature display member rises, and its upper surface can be seen through the transparent portion of the container.

  In the waste water valve device according to claim 4, the valve body is moved to the large diameter portion in the valve box by pushing the container and pushing down the valve body, the waste water valve device is opened, and the waste water starts. . When the temperature of the waste water is low, the shape memory material spring is in a contracted state (shrinks and becomes short), and the waste water operation continues. At this time, the spring made of shape memory material is also shortened, and the first magnet on the upper side of the spring is positioned at a low position. For this reason, the temperature display member is also immersed in the opaque or translucent liquid, and the temperature display on the upper surface of the member is not visually recognized.

  When the temperature of the water from the hot water source exceeds the spring and the transformation temperature of the spring, the spring extends, the valve body is pushed up to the small diameter part in the valve box, the waste water valve device is closed, and the waste water Stops. Further, the spring made of the shape memory material is extended by coming into contact with the warm water, and the first magnet on the upper side is pushed up. When the first magnet rises, a repulsive force is generated between the temperature display member and the second magnet, and the temperature display member rises due to the repulsive force. Thereby, the temperature display on the upper surface of the temperature display member is visually recognized through the transparent portion on the upper surface of the container.

  The rising state of the valve body is maintained by the water pressure from the hot water source. This state continues until the next time the container is pushed.

  According to the warm water washing apparatus of the fifth aspect, the waste water can be flowed at a sufficient flow rate by opening the diaphragm valve.

  Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a system diagram of a hot water cleaning apparatus according to an embodiment, FIG. 2 is a sectional view of a diaphragm valve, and FIGS. 3 to 5 are sectional views of a waste water valve apparatus.

  In this embodiment, the hot water cleaning device is installed in a toilet room such as a hotel where hot water piping is routed around a wall or the like. Since warm water is supplied from this warm water pipe, the warm water washing apparatus is not provided with a warm water tank with a heater. However, the present invention can also be applied to a hot water cleaning apparatus having a hot water tank with a heater.

  A hot water supply tap 1 and a water supply pipe 2 are connected to a hot water stop cock and a water stop cock provided on a wall of a toilet room, etc., and hot water from the hot water supply pipe 1 via a check valve 3 is connected to a thermostat mixing valve 4. It is possible to introduce normal temperature water from the water supply pipe 2 into the thermostat mixing valve 4.

  The mixed water in which hot water and water are mixed by the thermostat mixing valve 4 is supplied to the pipe 5, the high temperature shutoff valve 6 with a pressure reducing valve 6, the pipe 7, the flow control valve 8 having the knob 8 a for adjusting the cleaning strength, and the pipe 9. Through the cleaning nozzle 10. The washing nozzle 10 is configured to eject the introduced hot water obliquely upward from the tip of the nozzle 10a toward the human buttock.

  A pipe 11 for waste water branches from the pipe 7. This pipe 11 is connected to the inlet 21 of the diaphragm valve 20. A drain water pipe 12 is connected to the outlet 22 of the diaphragm valve 20 and is routed so as to discharge cold water to the toilet bowl. A pipe 13, a waste water valve device 30, and a pipe 14 are connected to the back pressure chamber outlet 23 of the diaphragm valve 20 in this order so as to guide water from the back pressure chamber 24 to the pipe 12.

  As shown in FIG. 2, a cylindrical valve seat 25 is erected in the diaphragm valve 20 so as to separate the inflow port 21 and the outflow port 22, and is seated on the valve seat 25 from above. A diaphragm valve body 26 is installed. A diaphragm valve body 26 divides the inside of the diaphragm valve 20 into a main flow path 27 and a back pressure chamber 24. The valve body 26 is provided with a small hole 26 a that communicates the main flow path 27 and the back pressure chamber 24. A back pressure spring 28 is disposed in the back pressure chamber 24 to urge the valve body 26 in the direction of seating on the valve seat 25.

  As shown in FIGS. 3 to 5, the waste water valve device 30 has a substantially cylindrical shape, and is disposed in the valve box 31 so as to be movable in the vertical direction. And a spring 35 made of a shape memory material and the like disposed on the lower side of the valve body 34.

  In the valve box 31, the lower part is a large diameter part 31a having an inner diameter larger than that of the upper part, and the upper part is a small diameter part 31b having an inner diameter smaller than that of the lower part. An inflow port 32 is provided in the large diameter portion 31a, and an outflow port 33 is provided in the small diameter portion 31b. The pipe 13 from the diaphragm valve 20 is connected to the inlet 32. A pipe 14 that joins the waste water pipe 12 is connected to the outlet 33.

  The valve body 34 has an outer diameter substantially equal to the inner diameter of the small diameter portion 31b. As shown in FIG. 4, when the valve body 34 is located in the large diameter portion 31a, the inlet port passes through a gap between the outer peripheral surface of the valve body 34 and the inner peripheral surface of the large diameter portion 31a. Water can flow from the outlet 32 to the outlet 33, and the waste water valve device 30 is opened. Further, as shown in FIGS. 3 and 5, when the valve body 34 is engaged in the small diameter portion 31b, the flow of water from the inlet 32 to the outlet 33 is blocked, and the waste water valve device 30 is closed. It becomes a state. Reference numeral 34a denotes a packing that seals between the outer peripheral surface of the valve body 34 and the inner peripheral surface of the small diameter portion 31b.

  The spring 35 is disposed between the lower surface of the valve body 34 and the bottom surface 31 c of the valve box 31. The spring 35 is exposed in the valve box 31, and the water flowing into the valve box 31 from the inlet 32 directly contacts the spring 35.

  When the temperature of water in contact with the spring 35 is lower than the transformation temperature of the shape memory material, the spring 35 is in a contracted state (shrinks in the vertical direction and shortens), and the temperature of the water is reduced to the shape memory material. If it is higher than the transformation temperature, it will be in an extended state (elongated in the vertical direction). When the spring 35 is in the contracted state, the valve body 34 is pulled down by the spring 35 and is positioned in the large diameter portion 31a. When the spring 35 is in the extended state, the valve body 34 is pushed up by the spring 35 and within the small diameter portion 31b. Engage with.

  As the shape memory material of the spring 35, a shape memory alloy having a transformation temperature of about 33 to 37 ° C. is suitable.

  A cylindrical body 36 is provided on the upper side of the valve body 34. The cylindrical body 36 is arranged with the cylinder axial direction as the vertical direction, the lower end is connected to the valve body 34, and the upper end projects upward from the upper surface opening 31 d of the valve box 31, that is, out of the valve box 31. Reference numeral 36 a denotes a packing that seals between the outer peripheral surface of the cylindrical body 36 and the inner peripheral surface of the upper surface opening 31 d of the valve box 31. The cylindrical body 36 moves up and down integrally with the valve body 34. The length of the cylindrical body 36 in the cylinder axis direction is such that the upper end of the cylindrical body 36 can protrude upward from the valve box 31 even when the valve body 34 is lowered to the lowering limit.

  A water passage opening 37 that communicates the inside and outside of the cylindrical body 36 is provided in the middle of the cylindrical body 36 in the vertical direction. In this embodiment, a plurality of water flow openings 37 are provided. As shown in the drawing, the at least two water flow openings 37, 37 are arranged in a positional relationship facing the diameter direction of the cylindrical body 36. Further, as shown in FIG. 4, the water flow opening 37 is disposed at substantially the same height as the outlet 33 in the small diameter portion 31b when the valve body 34 is located at the lower limit. As shown in FIGS. 3 and 5, the water flow opening 37 is positioned lower than the packing 36a even when the valve element 34 rises to the upper limit.

  Inside the cylindrical body 36, a spring 38 made of a shape memory material as a temperature sensitive body, a first magnet 39, and a magnetic body 40 that attracts the first magnet 39 are arranged. The spring 38 is made of a shape memory material having substantially the same transformation temperature as that of the shape memory material constituting the spring 35. The first magnet 39 is disposed on the upper side of the spring 38 inside the cylindrical body 36 so as to be movable up and down. Further, the magnetic body 40 is disposed below the spring 38.

  The shape memory material of the spring 38 is preferably a shape memory alloy having a transformation temperature that is the same as or slightly lower than the shape memory material of the spring 35 (for example, about 0 to 3 ° C., particularly about 1 to 2 ° C.).

  In this embodiment, the magnetic body 40 is also made of a magnet, and the first magnet 39 and the magnetic body 40 are arranged so that the N pole and the S pole face each other. However, the magnetic body 40 may be a metal piece such as iron that can be attracted by the magnet 39.

  As shown in FIGS. 3 to 5, the spring 38 is supported by the magnetic body 40 at substantially the same height as the water flow openings 37 in the cylindrical body 36 and faces the water flow openings 37. That is, the water that has flowed into the cylindrical body 36 through each water flow opening 37 is in direct contact with the spring 38. Similarly to the spring 35 described above, the spring 38 is also shortened (shrinks in the vertical direction) when the temperature of water in contact with the spring 38 is lower than the transformation temperature of the shape memory material of the spring 38. Thus, when the temperature of the water is higher than the transformation temperature of the shape memory material, the water is stretched (elongated in the vertical direction).

  As the spring 38 expands and contracts, the first magnet 39 moves up and down inside the cylindrical body 36.

  When the temperature of the water in contact with the spring 38 is lower than the transformation temperature of the shape memory material, the attraction force between the first magnet 39 and the magnetic body 40 pushes and shrinks the spring 38 to reduce the first magnet 39. When the temperature of the water becomes higher than the transformation temperature of the shape memory material and the spring 38 is extended, the first force is generated by the extension force of the spring 38. It is strong enough to allow the magnet 39 to be separated from the magnetic body 40.

  A container 43 containing a temperature display member 42 is integrally connected to the upper end of the cylindrical body 36. The upper end side of the inner hole of the cylindrical body 36 is closed by the bottom surface of the container 43. The temperature display member 42 is disposed in the container 43 so as to be movable in the vertical direction. An opaque or translucent liquid is sealed in the container 43. As this liquid, for example, colored silicone oil can be used.

  A window-like transparent portion 44 is provided on the upper surface of the container 43 so that the inside of the container 43 can be visually recognized through the transparent portion 44.

  The temperature display member 42 is provided with a second magnet (not shown) that repels the first magnet 39. That is, the second magnet and the first magnet 39 are arranged so that the N poles or the S poles face each other across the bottom surface of the container 43. In addition, the whole temperature display member 42 may be comprised by the 2nd magnet, and the temperature display member 42 may be partially comprised by the 2nd magnet.

  On the upper surface of the temperature display member 42, temperature display colors, figures, or characters (not shown) are provided. Examples of the display include red coloring associated with warm water, characters such as “warm” or “HOT”, and the like. However, the display on the upper surface of the temperature display member 42 is not limited to this.

  The waste water valve device 30 is installed on an operation panel (not shown) of a toilet seat box installed on the toilet bowl.

  The usage method and operation of the hot water cleaning apparatus configured as described above will be described.

  When the user's buttocks are washed with the washing nozzle 10 after the stool, first, the transparent portion 44 of the container 43 is visually checked, and whether or not the temperature display of the temperature display member 42 is visually recognized through the transparent portion 44 is confirmed. .

  When the temperature of the water in the valve box 31 is lower than the transformation temperature of the shape memory material of the spring 38, the spring 38 is pushed by the attractive force of the first magnet 39 and the magnetic body 40 as shown in FIG. The first magnet 39 is contracted to a shortened state, and the first magnet 39 is located in a low position in the cylindrical body 36. Accordingly, a repulsive force that pushes up the temperature display member 42 from the first magnet 39 to the temperature display member 42 in the container 39 does not act, and the temperature display member 42 is opaque or translucent in the container 43. It is immersed in the liquid. Therefore, the temperature display of the temperature display member 42 is not visually recognized through the transparent portion 44.

  In this case, before operating the cleaning switch (not shown) by the cleaning nozzle 10, the container 43 is pushed and the valve body 34 is pushed down to open the waste water valve device 30.

  At this time, as shown in FIG. 4, when the temperature of the water in the valve box 31 is lower than the transformation temperature of the shape memory material of the spring 35, the pressing force to the container 43 is released after the container 43 is pushed down. Even so, the spring 35 on the lower side of the valve body 34 remains contracted, and the valve opening state of the waste water valve device 30 continues.

  When the waste water valve device 30 is opened, water flows out from the back pressure chamber 24 of the diaphragm valve 20 through the pipe 13, so that the water pressure in the back pressure chamber 24 is higher than the water pressure in the main flow path 27. Due to this water pressure difference, the diaphragm valve element 26 is separated from the valve seat 25, and water is discharged from the main flow path 27 through the outlet 22 and the pipe 12 to the toilet bowl. At this time, a part of the water in the main flow path 27 flows into the back pressure chamber 24 through the small hole 26 a, and from the back pressure chamber 24 through the pipe 13, the waste water valve device 30 and the pipe 14. It flows out to the pipe 12.

  Along with this discarded water, hot water generated by the thermostat mixing valve 4 is supplied to the pipe 5.

  This hot water flows in the order of the pipe 5, the high-temperature cutoff valve 6 with a pressure reducing valve, the pipes 7 and 11, the diaphragm valve 20, and the pipe 12. Further, a part of this hot water flows from the small hole 26a of the diaphragm valve body 26 through the back pressure chamber 24 and the pipe 13 to the valve box 31 of the discarded water valve device 30 to increase the water temperature in the valve box 31. Let When the temperature of water in contact with the spring 35 and the spring 38 in the valve box 31 becomes equal to or higher than the transformation temperature of the shape memory material of the spring 35 and the spring 38, the spring 35 and the spring 38 are extended.

  Due to the extension of the spring 35, the valve body 34 rises and engages in the small diameter portion 31b of the valve box 31, and the waste water valve device 30 is closed. As a result, since the outflow of water from the back pressure chamber 27 of the diaphragm valve 20 to the waste water valve device 30 is stopped, the diaphragm valve body 26 is caused by the water flowing into the back pressure chamber 24 from the main flow path 27 through the small hole 26a. The diaphragm valve body 26 is finally seated on the valve seat 25 and the diaphragm valve 20 is also closed. This stops the waste water.

  Further, in the waste water valve device 30, as shown in FIG. 5, the first magnet 39 is pushed up by the extension of the spring 38 in contact with the hot water. When the first magnet 39 rises, a magnetic repulsive force is generated between the first magnet 39 and the temperature display member 42 in the container 43, and the temperature display member 42 is moved into the container 43 by the repulsive force. It is pushed up to near the liquid level. As a result, the temperature display on the upper surface of the temperature display member 42 is visually recognized through the transparent portion 44 on the upper surface of the container 43, and the toilet user can visually recognize that the water has been discarded.

  In addition, the rising state of the valve body 34 is maintained by the water pressure of the warm water transmitted into the valve box 31 through the small hole 26a, the back pressure chamber 24, and the pipe 13. This state continues until the container 43 is pushed next time.

  After the temperature display of the temperature display member 42 is visually recognized on the transparent portion 44, the cleaning switch by the cleaning nozzle 10 is operated. At this time, since the discarded water has been finished, warm water is jetted to the toilet user's buttocks immediately after the start of washing.

  When time elapses after the container 43 is pushed to be discarded and the temperature of the hot water in the valve box 31 decreases, the temperature of the water in contact with the spring 38 becomes equal to or lower than the transformation temperature of the shape memory material of the spring 38. Then, the first magnet 39 presses and contracts the spring 38 by the attractive force between the first magnet 39 and the magnetic body 40 and descends. Thereby, the repulsive force between the first magnet 39 and the temperature display member 42 is reduced, and the temperature display member 42 is submerged in the opaque or translucent liquid in the container 43 by its own weight. As a result, the temperature display on the upper surface of the temperature display member 42 is not visually recognized through the transparent portion 44 on the upper surface of the container 43, and the toilet user recognizes that the temperature of the washing water has decreased.

  As described above, according to this hot water cleaning apparatus, the temperature display member 42 moves in conjunction with the expansion and contraction of the shape memory material spring 38 as a temperature sensitive body, thereby displaying the temperature of the hot water from the hot water source. Therefore, this temperature display is performed without using a power source.

  In this hot water washing apparatus, the shape memory material spring 38 is arranged so as to come into contact with the water from the hot water source, so that the temperature display member 42 moves quickly.

  The above embodiment shows an example of the present invention, and the present invention is not limited to the above embodiment.
