Description

  The present invention relates to a water leakage treatment method for a hot water cleaning apparatus used in a toilet and a hot water cleaning apparatus using the same.

  For example, as shown in FIG. 9, this type of hot water cleaning apparatus includes a main body w having a toilet seat and a valve lid (not shown), and a hot water supply mechanism d for cleaning is provided in the main body w. In the hot water supply mechanism d, the water receiving part c in the main body w is connected to a water supply pipe g to a low tank for drainage (which may be a flush valve type or a toilet bowl integrated type) f by a connecting pipe b. A branch connection is made to a water supply part a having a built-in water stop valve h. The water stop valve h remains open during normal times other than connection work and connection release work, the low tank f is supplied with water based on the water level adjustment by the float valve f1, and the hot water supply mechanism d has a water stop solenoid valve s. Water is supplied in a timely manner by opening and closing according to the presence or absence of a water supply signal. The water receiving part c receives water through the strainer o and supplies it to the hot water supply mechanism d side through the check valve p. The water receiving part c includes a drain plug q for cleaning and the like. The warm water supply mechanism d heats the received water by the heater i to make warm water, supplies it to the cleaning nozzle by the pump j, and cleans the object to be cleaned. The cleaning is mainly a body buttocks and a bidet local cleaning, but in the illustrated example, in addition to the dedicated buttocks cleaning nozzle l, the bidet cleaning nozzle m or the common cleaning nozzle, the cleaning for cleaning the buttocks cleaning nozzle l and the bidet cleaning nozzle m is performed. A nozzle n is provided and is used by switching according to an operation signal.

  In addition to the instantaneous heat exchange type shown in the figure, the hot water supply mechanism d includes a hot water storage type that supplies hot water to be generated while storing hot water. Especially in the instantaneous heat exchange type, the water received by the water receiving part c is passed through the heat exchange part with the heater i via the constant flow valve r, the water stop solenoid valve s and the flow sensor t, and the flow rate and the heater i are energized. It is used for washing while generating warm water at a temperature set in a precise relationship with the W number. Therefore, in the instantaneous water heater type, the water stop solenoid valve s described above is opened every time various cleaning signals are output, and the water stop solenoid valve s is closed by a cleaning end signal. Between the water stop solenoid valve s and the flow rate sensor t, an air release valve u that prevents the generation of negative pressure and an escape passage v that discharges excess water into the toilet bowl are provided.

On the other hand, for the water supply hose that connects the hot water washing device to the tap at the end of the water pipe, the outermost surface is made of styrene elastomer or olefin elastomer, so that weather resistance is good and durability is improved. In addition, a technique for making it environmentally friendly during incineration is also known (see, for example, Patent Document 1).

  However, when installing the hot water washing apparatus, it is necessary to perform a construction for connecting the water receiving part c of the hot water supply mechanism d and the water supply part a on the water pipe e side by the connecting pipe b. The connection between the connection pipe b and the water receiving part c is a straight connection, but the water supply part a is a branch connection part that connects the water supply pipe e to the water supply pipe g and the connection pipe b. If the toilet is installed, the cheese-type connector may be connected to the water supply part a, but in the case of retrofitting, the connection between the water supply part a and the water supply pipe g is removed and the cheese-type connector is used. It will take time and effort to rework. In any case, even if the hot water cleaning device is functioning normally, there is a problem of water leakage if the water supply pipe line connection is incomplete. In addition, it is used for a long period of 10 years or more after construction, and there is a situation where the problem of water leakage cannot be solved, such as an unexpected force is applied to the pipe connection due to fluctuations in water pressure. Such water leakage occurs on the floor of a semi-residential space, such as a flooring of a toilet room, and also leaks in the primary side with respect to the water stop solenoid valve s, that is, in a range where water pressure from the water pipe e always works. This is a big problem because the floor surface is likely to be submerged, for example, because it does not stop and does not enter frequently, and the discovery tends to be delayed.

  In addition, although the position of the water supply port in the toilet room of the water supply pipe e is almost behind the installation position of the toilet bowl, the position of the water supply port is different from side to side and the distance is different. For this reason, it is usually a flexible hose. However, excessive bending, twisting, compression, and rubbing during routing and connection can cause fatigue and cause early water leakage.

  The present inventor has thought to detect and notify these water leaks and encourage the user to take measures. However, depending on the amount of water leaks, it may be unavoidable that the floor surface is flooded.

  Therefore, it is required to take measures to minimize the occurrence of damage caused by inadequate piping connections or inadequate handling of connecting pipes.

  An object of the present invention is to provide a hot water cleaning apparatus that can treat water leakage without any other effects even if there is water leakage in the connection range of the water supply section on the water pipe side and the water receiving section on the main body side, and can notify if necessary. There is.

  According to the first aspect of the present invention for achieving the above object, when there is water leakage in a connection range connected by a connecting pipe from a water supply unit outside the main body to a water receiving portion of the hot water supply mechanism in the main body, This water leakage is received in a cover tube covering the outside of the connection range, guided into the main body, and drained into the toilet bowl through a predetermined drainage path in the main body.

  According to such a feature of the first aspect, even if there is water leakage due to poor connection or poor connection pipe in the connection range of the water supply part outside the main body and the water receiving part inside the main body, the water leak is In the toilet bowl where the hot water washing device is installed in the specified drainage path in the main body, thus avoiding electrical equipment, etc. by receiving it in the cover tube covering the outside of the connection range It can be treated to drain.

  According to the third aspect of the present invention, such a method includes a cleaning nozzle and a hot water supply mechanism for supplying water to the cleaning nozzle by using the water supply unit connected to the external water supply unit by a connecting pipe as hot water. And a cover tube that covers the outer periphery of the connection range so that if there is water leakage in the connection range from the water supply unit to the water reception unit, the water leaks into the main unit. It implement | achieves by the warm water washing | cleaning apparatus characterized by including the drainage path which drains the water leakage which led to the inside of a main body in the toilet bowl by the predetermined | prescribed path | route in a main body.

  According to the second aspect of the present invention, in the first aspect, it is further characterized in that if there is water leakage, it is detected by a water leakage detection sensor and a visual or audio notification is given.

  According to the feature of the second aspect as described above, it is easy to notice early on the user by notifying the user that there is water leakage by detecting the water leakage with the water leakage sensor. In visual notification, lighting display with characters on the operation unit or the like can be performed, and the content of the notification and the content of the measure can also be specified. The auditory notification has an advantage that it can be notified to the user outside the toilet room, and if the voice is used, the content of the notification and the content of the measure can be recognized.

  According to the fourth aspect of the present invention, in the third aspect, further, the drainage path is formed by the main body itself separated from the electrical equipment area in the main body or formed by a pipe line disposed in the main body. It is characterized by.

  According to such a feature of the fourth aspect, in addition to the third aspect, the drainage path is provided separately from the electrical equipment area, and the leaked water guided into the main body by the cover tube touches the electrical equipment. Of course, it is possible to prevent the steam generated by heat from the heat exchange section, hot water storage section, etc. from reaching the electric equipment, and to treat the waste water into the toilet bowl. Further, in the case of using a pipeline, there is an advantage that a special molding path is not required in the main body.

  According to the fifth aspect of the present invention, in addition to any one of the third and fourth aspects, a leak sensor that detects a leak that the cover pipe leads into the receiving body, and a leak detection signal by the leak sensor It is characterized by having a water leakage notification means for visual and / or auditory notification when there is.

  According to such a feature of the fifth aspect, the method of the second aspect can be realized in any one of the third and fourth aspects.

  According to a sixth aspect of the present invention, in the fifth aspect, the water leakage sensor further includes a position in front of the connection portion with the water receiving portion in the main body in the cover tube, and a water supply portion or a water supply portion. It is characterized in that it is provided at a position on the sealed side in the vicinity of the connecting portion.

  According to such a feature of the sixth aspect, in addition to the fifth aspect, the water leakage sensor can be located near both ends of the cover tube that are easy to install. Even if water leakage occurs on either side, there is an advantage that it is easy to detect early. However, since the water leakage is always guided into the main body, the water leakage can be reliably detected if it is on the connection portion side with the water receiving portion.

  According to the present invention, even if there is water leakage due to poor connection or poor connection pipe in the connection range of the water supply part outside the main body and the water receiving part inside the main body, the leakage is put into the cover pipe around the connection pipe. Since it is drained into the stool by a predetermined drainage path that is confined and guided into the main body to avoid electrical equipment in the main body, the surrounding floor surface may be submerged by water leakage, affecting the electrical equipment in the main body. Can be avoided.

  In addition, it is possible to automatically detect leaks and notify the user to promptly take action.

  The water leakage treatment method of the hot water cleaning apparatus of the present invention and the hot water cleaning apparatus using the same will be described with reference to FIGS. 1 to 8 for the understanding of the present invention.

  As shown in FIG. 1, the hot water cleaning apparatus 10 of the present embodiment has a main body 2 installed on the rear part of the toilet 1, and the toilet seat 3 stands on the main body 2 from the mounting position on the toilet 1. In addition to the basic structure that supports each so that the toilet lid 4 can be pivoted to the raised position and the toilet lid 4 can be opened and closed on the toilet seat 3 placed in the toilet bowl 1, a virtual line in FIG. The warm water supply mechanism 5 as described above is incorporated. The hot water supply mechanism 5 is connected by a connecting pipe 9 and a water supply part 8 of a water pipe 7 protruding on the wall surface 6 of the rear part of the toilet 1 shown in FIG. 1 as in the examples shown in FIGS. A water receiving part 11 for receiving water, making the received water warm water, and washing operation from the operation part 13 provided on the side wall 12 of the toilet bowl 1 or the main body 2 as shown in FIG. In accordance with the cleaning end operation, as described above, it is supplied to the cleaning nozzle 14 or the like for cleaning, or the supply is stopped. The water receiving part 11 has the same function as that described above, including the drain plug 11a.

  Since connection with the connecting pipe 9 between the water supply unit 8 and the water receiving unit 11 is indispensable, and the installation work is left to the contractor or the user, the hot water cleaning device 10 is functioning normally as described above. However, if there is a deficiency in the connection of the water supply pipe, there is a problem of water leakage in the water supply pipe where water pressure is constantly applied. In addition, since PVC and other known flexible hoses are used for free routing of the connecting pipe 9, fatigue and early fatigue due to excessive bending, twisting, compression, and rubbing during routing and connection. It may cause water leakage.

  In order to avoid such water leakage from flooding the floor where flooring of the toilet room is performed, in the present embodiment, examples of FIGS. 1 to 6A, FIGS. 6B and 7 are used. As shown in the example, when there is water leakage in the connection range connected by the connecting pipe 9 from the water supply part 8 to be located outside the main body 2 to the water receiving part 11 of the hot water supply mechanism 5 in the main body 2, This water leakage is received in the cover tube 15 covering the outer periphery of the connection range and guided into the main body 2, and a predetermined drainage path 17 as shown in FIGS. 2, 5, 6 (a) and 6 (b) in the main body 2. A water leakage treatment method of draining into the toilet bowl 1a of the toilet bowl 1 is adopted. Thereby, even if there is water leakage due to poor connection or poor connection pipe in the connection range of the water supply part 8 outside the main body 2 and the water receiving part 11 inside the main body 2, the water leaks around the outside of the connection range. It will be received by the covering cover tube 15 and will not leak to the outside. The cover tube 15 guides the received water leakage into the main body 2, and the toilet 1 in which the hot water cleaning device 10 is installed in a predetermined drainage path 17 in the main body 2 to avoid the control board electrical equipment in the main body 2. The waste water in the toilet bowl 1a can be discharged. The cover tube 15 is also flexible like the connection tube 9 so that it can be freely routed when the connection tube is connected.

  As described above, even if water leaks due to poor connection or poor connection pipe in the connection range of the water supply part 8 outside the main body 2 and the water receiving part 11 in the main body 2 due to poor connection or poor connection pipe, the leakage is connected to the connection pipe 9. Since it drains into the toilet bowl 1a through a predetermined drainage path 17 that is confined in the outer cover tube 15 and guided into the main body 2 to avoid electrical equipment in the main body 2, the surrounding floor surface is submerged by water leakage. It can be avoided that the electric equipment in the main body 2 is affected.

  In order to realize such a method, the hot water cleaning apparatus 10 of the present embodiment is configured such that the water receiving portion 11 is connected to the cleaning nozzle 14 described above in the main body 2 and the external water supply portion 8 by the connecting pipe 9. It has a hot water supply mechanism 5 that supplies the washed water as warm water to the cleaning nozzle 14, and if there is water leakage in the connection range from the water supply part 8 to the water receiving part 11 in the main body 2, this water leakage is guided into the main body 2 A cover tube 15 is provided so as to cover the outer periphery of the connection range, and a drainage passage 17 is provided for draining the water leaked to the inside of the main body 2 into the toilet bowl 1a by a predetermined route in the main body 2. More specifically, the end of the cover pipe 15 on the water supply section 8 side is covered in a sealed state around the outside of the connection range, and the end of the cover pipe 15 on the water receiving section 11 side is Introductory room provided to surround the outside of the water receiving part 11 slightly larger 3 connection pipe 9 is connected together fitted with a retaining flange portion 15a on the inner periphery of the opening 23a extending therethrough for. Thus, the water leakage received by the cover tube 15 is guided into the introduction chamber 23 by natural flow or overflow without being affected by the height relationship between the water supply unit 8 and the water receiving unit 11. As shown in FIGS. 5 and 6A, the predetermined drainage path 17 is a closed path connected to the introduction chamber 11b partitioned and formed in the main body 2 itself by a matching structure of the bottom plate 21 and the cover plate 22 of the main body 2. As shown in FIG. 6B and FIG. 7, it can be provided as a pipe line by a tube connected to the introduction chamber 23. In any case, the drainage path 17 is a closed path, so that the leaked water guided to the introduction chamber 23 in the main body 2 by the cover tube 15 does not touch the electrical equipment, and from the heat exchange section, hot water storage section, etc. It is possible to prevent the steam generated due to heat and the like from reaching the electric equipment and to treat the waste water into the toilet bowl 1a. Further, when the drainage path 17 is a pipe, it is closed as it is, and there is an advantage that a special molding path is not required in the main body 2. Further, in the illustrated example, the drainage channel 17 shares a return port 24 that overflows excess water in the middle of the water supply route from the water receiving unit 11 to the hot water supply mechanism 5 and returns it to the toilet bowl 1a as described above. In addition, when the overflow water is dropped on the remaining water surface 1b to return it into the toilet bowl 1a, it will bounce off or fall off and become uncomfortable for the user in use. Therefore, as shown in FIG. It falls on the inclined surface 1c and is transferred down to the remaining water surface 1b to prevent rebound and noise. Therefore, the same effect can be obtained when draining the leaked water into the toilet bowl 1a. However, the drainage into the toilet bowl 1a of the leaked water can be announced on the remaining water surface 1b by making a noise by making a sound. In this case, when the drainage path 17 is a pipe, the pipe can be protruded from the return port 24, so that handling different from the return of the overflow water can be easily performed.

  Further, when there is water leakage, the water leakage sensor 31 detects it and makes a visual or audible notification. In this way, the leakage sensor 31 detects the leakage and notifies the user that there is leakage, making it easier to notice early. In the visual notification, a lighting display with characters on the operation unit 13 or the like can be performed, and the content of the notification or the content of the measure can also be clearly indicated. The auditory notification has an advantage that it can be notified to the user outside the toilet room, and if the voice is used, the content of the notification and the content of the measure can be recognized. It includes a water leakage sensor 31 that detects a water leakage that the cover tube 15 leads into the receiving body 2 and a water leakage notification means 33 that provides a visual or audible notification when there is a water leakage detection signal from the water leakage sensor 31. What is necessary is just to operate the display part 13a, the buzzer 13b, a speaker, etc. by the liquid crystal of the operation part 13, a lamp | ramp, etc. according to the notification form.

  As shown in FIG. 1, the water leakage sensor 31 is located in the cover tube 15 in front of the connection portion with the water receiving portion 11 in the main body 2 or in the vicinity of the connection portion with the water supply portion 8 or the water supply portion 8. If it is provided at the position of the sealed airtight side, the water leakage sensor 31 is located near both ends of the cover tube 15 that are easy to install, and installation is not troublesome. There is an advantage that it is easy to detect at an early stage, even if water leakage that occurs easily on either side occurs. However, since the water leakage is always guided into the main body 2, the water leakage can be reliably detected if it is on the connection portion side with the water receiving portion 11.

  As shown in FIG. 1, the connection pipe 9 is connected to the water supply section 8 by one or more of the cheese 25 connecting the water stop valve 8 a of the water supply section 8 and the water supply pipe 19 to the low tank 18. As shown in FIGS. 3 (a), 3 (b), and 8 (a) to 8 (e), it is elastically fitted to the branch connection port 25a having a strip. Connection with the water receiving part 11 is performed by elastically fitting to the connection port 11b having a plurality of retaining seal ridges of the water receiving part 11 as shown in FIGS. However, it is not limited to this. On the other hand, as shown in FIGS. 2, 3 (a), 3 (b), and 8 (a) to 8 (e), the sealed state by sealing the cover tube 15 on the water supply unit 8 side is cheese. 25 at the fitting part around the base portion of the branch connection port 25a, and the cover tube 15 covers the connection boundary portion 26 shown in FIGS. 3 (a) to 3 (c) between the connecting pipe 9 and the water supply part 8 and from there. If there is any water leakage, it is received in the cover tube 15. However, the outer periphery of the water stopcock 8a and the water supply pipe 7 and the water supply so as to cover the whole connection part at the three places by the cheese 25 or the whole including the water stopcock 8a as shown in FIG. It can also be set in a sealed state at the fitting portion with the outer periphery of the pipe 19, and can cope with water leakage after the water pipe 7.

  In particular, in the example shown in FIGS. 3A to 3C, the water stop electromagnetic valve 16 originally installed in the main body 2 is moved to the water supply unit 8 side in the connection range, and the main unit 2 side or the operation unit 13 is moved. Remote control is performed from the side by wireless or wired. Thereby, the piping after the water stop solenoid valve 16 becomes a secondary side, and the primary pressure which is a water supply pressure is not always applied, and there is an advantage that water leakage into the cover tube 15 itself can be suppressed. In this sense, if the water stop solenoid valve 16 is provided on the water supply unit 8 side, the primary pressure is not always applied to the connection part between the water supply unit 8 and the connecting pipe 9. Since the primary pressure is not always applied to the connecting portion of the portion 8 itself, it is more suitable for suppressing water leakage including reducing fatigue of the seal packing provided at the connecting portion.

  However, if the remote operation is wireless, the communication mechanism causes an increase in cost, and if it is wired, the external wiring is deteriorated in appearance and may be damaged, so that a waterproof structure is provided between the connecting tube 9 and the cover tube 15. This leads to the wiring of the conducting wires, which is troublesome and increases costs. From this point of view, it is advantageous in terms of cost to provide the water stop solenoid valve 16 in the main body 2. In addition, when providing the conducting wire for the wired remote operation between the connection pipe 9 and the cover pipe 15, it is suitable to wire to the connection pipe 9 side with high support stability.

  The introduction chamber 23 shown in FIGS. 4, 5, and 6 (a) is formed in a state of being connected to each other together with the drainage path 17 described above between the mating portions of the bottom plate 21 and the cover plate 22 of the main body 2. The opening 23a is also formed in a two-ply structure with the bottom plate 21 and the cover plate 22, and fitting with the end portion of the cover tube 15 having the retaining flange portion 15a is performed by clamping pressure by the opening 23a. The introduction chamber 23 in the example shown in FIGS. 6B and 7 is formed independently from the bottom plate 21 and the cover plate 22 and has an end portion having a retaining flange portion 15a of the cover tube 15 as shown in FIG. In addition to the opening 23a for elastic fitting, the connection port 11b has a seal structure by the O-ring 27 extending from the water receiving portion 11 and is sealed by the O-ring 28 on the outer periphery of the base connection port 11c. It has a structure and has an opening 23b to be fitted outside, and also has a connection hole 23c for connecting the base portion of the drainage passage 17 by a tube by press fitting or bonding as shown in FIG. 6B. .

  Since the cover tube 15 only accepts water leakage and guides it into the main body 2, the water pressure does not work unless the connection tube 9 is ruptured. Therefore, the pressure resistance is low and the connection tube 9 is more flexible and flexible. Can be made of a high material. As a result, when the hot water washing apparatus 10 is installed, the connecting pipe 9 and the cover pipe 15 can be easily routed, and the user can touch the exposed cover pipe 15 after installation to exert an external force. However, since the cover tube 15 has flexibility and flexibility, the external force can be buffered and is not easily damaged. In addition, the cover tube 15 does not need to be sealed so much for sealing on the water supply unit 8 side or for connection with the water receiving unit 11, but it is sufficient to prevent secondary leakage from the cover tube 15. It is preferable to ensure the state. Therefore, in the example shown in FIG. 3A, the elastic ring 34 provided integrally with the end of the cover tube 15 is elastically fitted to the outer periphery of the base of the branch connection port 25 a of the cheese 25. However, other seal structures can be employed as required. In the example shown in FIG. 3B, the initial double structure of the connecting pipe 9 and the cover pipe 15 and the initial connection structure of these and the branch connection port 25a are particularly inconvenient in handling. Since there is an advantage that it can be handled as one part which is not bulky, the metal ring 35 is fitted on the outermost circumference of the fitting portion of the connecting pipe 9 and the cover pipe 15 to the outer circumference of the branch connection port 25a and caulking is performed. The assembly is compressed and integrated by the portion 35a. However, the integration is not limited to this, and various methods such as adhesion, welding, and resin winding by insert molding can be used.

  8A to 8E show various non-integrated sealing structures. In any case, unlike the cases of FIGS. 3A to 3C, the branch connection port 25a of the cheese 25 has a plurality of retaining seal ridges by being internally fitted through an O-ring 36. The connection port 37 is provided, and the end of the cover tube 15 is fitted and sealed to the outer periphery of the branch connection port 25a of the cheese 25 exposed thereby. In the example of FIG. 8A, the reduced diameter portion 15b formed at the end of the cover tube 15 is elastically fitted to the outer periphery of the base of the branch connection port 25a. On the other hand, in the example of FIG. 8 (e), the slightly reduced diameter portion 15c of the cover tube 15 is elastically fitted to the entire outer periphery of the branch connection port 25a having the retaining seal protrusions, and FIG. In the example of (d), a reduced-diameter portion 15d having a plurality of ridge-shaped thickening ridges on the outer periphery of the cover tube 15 and increasing the elastic force is elastically fitted. In the example of FIG. 8 (b), an inwardly folded portion 15e formed at the end of the cover tube 15 is fitted to the outer periphery of the branch connection port 25a, and the folded portion 15e is provided on the outer periphery of the branch connection port 25a. 25b is elastically fitted and sealed and prevented from coming off, and even if an internal pressure is applied, the folded portion 15e is pressed against the outer periphery of the branch connection port 25a by the internal pressure, so that it is easy to prevent water leakage. is doing. In the example of FIG. 8C, a metal screw ring 15f that is integrated by insert molding or the like is provided at the end of the cover tube 15, and the outer periphery of the branch connection port 25a has a seal structure with an O-ring 38. The fitted screw ring 39 has a seal structure with an O-ring 40 so that the screw ring 15f is screw-fitted. However, the O-ring 40 can be omitted if the screw fitting portion 41 is a fine screw with good sealing properties.

  INDUSTRIAL APPLICABILITY The present invention can be practically used for a water leakage treatment technique in a connection range by a connection ring between a water supply unit on a water pipe side and a water receiving unit of a hot water supply mechanism of a hot water cleaning device, and the water leakage is drained into a toilet bowl through the main body.
