Description

  The present invention relates to household piping equipment used for sinks, washstands, bathrooms, toilets, and the like.

  For example, as shown in FIG. 6, a conventionally known household piping facility of this type includes a water tank 51 of a sink to which water is supplied from a water tap (not shown), and an attachment provided on the bottom wall of the water tank 51. It is known to have a drainage channel connected to the hole 52 and a drainage trap 50 provided in the drainage channel, and this drainage trap 50 has a part of a drainage pipe 53 constituting the drainage channel formed in an S shape. It has a sealing part 54 formed in a curved shape, and the sewage-side odor is prevented from being diffused to the water tank side by the water accumulated in the sealing part 54 (for example, Patent Document 1 discloses this kind of Drain traps are disclosed).

  A trapezoidal drain trap 55 as shown in FIG. 7 is also known as another drain trap. This drain trap 55 is provided at the upstream end of the drainage channel, and a drain cylinder 57 that communicates with the sewage side is formed through the bottom wall of the bottomed cylindrical section 56 whose upper end opening is a drain outlet 61. Thus, the trap body 58 is formed, and the sealing cup 59 is attached to the drain cylinder 57 so as to cover the drain cylinder 57, thereby forming a sealing part at the bottom of the bottomed cylindrical part 56.

  By the way, household piping equipment provided with a drain trap in the drainage channel as shown in FIGS. 6 and 7 always stores water in the sealing portion of the drain trap when the faucet is closed. Etc. are easy to propagate, and the propagation of these microorganisms causes sliminess and bad odor in the sealed water, and is not hygienic. Therefore, it is necessary to periodically clean the sealing portion of the drain trap, but there is a problem that cleaning the sealing portion is very troublesome.

  In addition to the above, there is also known a water supply facility in which an electrode part for generating a sterilizing component by applying a voltage is provided in a sealing part of an S-type drain trap as shown in FIG. By applying a voltage to the inside of the sealed portion, the inside of the sealed portion is sterilized, thereby suppressing the occurrence of sliminess and bad odor in the sealed portion (for example, Patent Document 2).

However, in the domestic piping facility as shown in Patent Document 2 above, power from an external power source or a battery is conventionally used as the power source of the electrode unit for generating the sterilizing component in the sealed water part. In household piping equipment having an electrode part that generates a sterilizing component in the water part, electric energy is wasted, and the energy of the water flow generated when the water tap is opened is also effectively used. I was wasting a lot.

Electricity is generated using the water flow in the water supply pipe 4 (during use), and serves as a power source for the electrode unit 6 described later. The hydroelectric generator 5 is electrically connected to the control unit 7 built in the sink 1 through the lead wire 40 so that the electric power generated by the hydroelectric generator 5 can be charged by the control unit 7. .

  As shown in FIG. 2, a mounting hole 8 is formed at the bottom of the water tank 2, and a drainage channel constituted by an upstream drain trap 9 and a downstream drain pipe 11 is formed in the mounting hole 8. The upstream end of 42 is connected in communication. That is, the upstream end of the drainage channel 42 is a drainage port of the water tank 2.

Yes, and communicates with the sewage side through the drain pipe 11.

  The drain trap 9 shown in FIG. 2 has a trap body 12 attached in a state of being inserted into the attachment hole 8, and a funnel-shaped sealing cylinder 13 detachably attached to the trap body 12. The trap main body 12 is formed in a bottomed circular container shape with an upper end opened, and the upper end opening of the trap main body 12 serves as a drain outlet of the water tank 2. The trap body 12 has a flange portion 15 provided around the upper end of the peripheral wall 14 that is the outer periphery of the upper end of the trap body 12 mounted on a step portion 16 for mounting the trap body formed on the peripheral portion of the mounting hole portion 8. 15 is fixed to the peripheral portion of the attachment hole 8 by an attachment nut 17 and is attached to the attachment hole 8.

  The peripheral wall 14 of the trap body 12 is provided with a communication port portion 18 in which the upstream end portion of the connection pipe portion 10 is connected in communication, and a portion located above the communication port portion 18 in the peripheral wall 14 of the trap body 12. Is attached to the outer peripheral portion of the upper end of the water seal tube 13 without gaps, so that the water shown in FIG. 2 can be stored in the trap body 12 and the water seal tube 13 located below the communication port 18. A sealed portion 19 is formed. The mounting of the sealing cylinder 19 will be described in detail later.

  The sealing cylinder 13 has an upper end opening 20 that opens upward and a lower end opening 21 that opens downward. The drainage water flowing from the water tank 2 is received from the upper end opening 20 and the received drainage is received from the lower end opening 21. It flows out to the sealing part 19. That is, in this embodiment, this sealed cylinder 13 is a cylinder part. The sealing cylinder 13 is a lower small-diameter cylindrical portion 22 disposed in the center of the trap body 12 in a plan view, and an upper side that closes the space A between the small-diameter cylindrical portion 22 and the peripheral wall 14 of the trap main body 12. The large-diameter cylindrical portion 23.

  The small diameter cylindrical portion 22 has a main portion formed in a straight tube shape. The lower end of the small diameter cylindrical portion 22 is disposed lower than the communication port portion 18 and higher than the upper surface of the bottom wall 24 of the trap body 12, and the upper surface of the bottom wall 24 of the trap body 12 and the lower end of the sealing tube 13 are disposed. A gap B is formed between the two. Further, the lower end portion of the small-diameter cylindrical portion 22 is formed in a trumpet shape so that the inner diameter and the outer diameter are increased toward the lowermost end side.

  The lower end of the large diameter cylindrical portion 23 is integrally connected to the upper end of the small diameter cylindrical portion 22. The large-diameter cylindrical portion 23 is inclined so as to gradually increase in diameter as it goes upward from the lower end, and the upper end portion is an arcuate curved portion 25 that protrudes outward. Further, a corner portion 26 formed by the large-diameter cylindrical portion 23 and the small-diameter cylindrical portion 22 which is a connecting portion between the large-diameter cylindrical portion 23 and the small-diameter cylindrical portion 22 is also curved and formed in an arc shape projecting inwardly. ing.

  For example, as shown in FIG. 2, the sealing cylinder 13 is attached to the trap body 12 by providing a stepped portion 27 at a portion located above the communication port 18 of the peripheral wall 14 of the trap body 12 and the peripheral wall 14. A projecting piece 28 that protrudes inwardly is provided at a portion located slightly above the step portion 27, and a locking groove 29 is formed in the peripheral wall 14 of the trap body 12 by the step portion 27 and the projecting piece 28. Then, a locking piece 30 that protrudes outward is provided at the upper end of the water sealing tube 13, and after the locking piece 30 is disposed on the stepped portion 27, the sealing tube 30 is rotated to operate the locking piece 30. This is done by inserting into the locking groove 29 and sealing between the locking piece 30 and the locking groove 29 with a sealing member (not shown) such as rubber or packing. The means for attaching the water seal 13 to the trap body 12 is not limited to this. For example, although not shown, the seal cylinder 13 is placed on a portion located above the communication port 18 of the peripheral wall 14 of the trap body 12. A circumferential step is provided, and a flange that protrudes outward is formed at the upper end of the water seal tube 13, and the flange is placed on the placement step of the trap body without a gap via a seal member. Alternatively, without providing the sealing member as described above, the outer periphery of the upper end of the water seal tube 13 may be detachably attached in close contact with the inner periphery of the trap body 12, that is, the trap body. It is only necessary that the sealing cylinder 13 is detachably attached to the trap body 12 with no gap between the inner peripheral portion of the peripheral wall 12 and the outer peripheral portion of the upper end portion of the sealing cylinder 13.

  A hole is formed in a portion of the bottom wall 24 of the trap body 12 facing the lower end opening 21 of the sealing cylinder 13, and an electrode constituting a part of the bottom wall 24 of the trap body 12 is formed in the hole. The holding member 32 is provided in a watertight manner. As shown in FIG. 3, the upper end portion of the electrode holding member 32 protrudes upward from the bottom wall 24 of the trap body 12, and the protruding surface 32 a protruding upward from the bottom wall 24 is positioned higher toward the center portion. It is a curved surface.

  The electrode holding member 32 is provided with an electrode portion 6 that electrolyzes a sterilizing component in water stored in the sealed water portion 19 by applying a voltage, and this electrode portion 6 faces the lower end opening 21 of the sealed water tube 13. is doing. The electrode portion 6 includes a pair of electrodes 33 and 33, and the upper ends of the electrodes 33 and 33 protrude upward from the electrode holding member 32 and are arranged with a gap therebetween. That is, the upper ends of the electrodes 33 and 33 are disposed in the sealed portion 19, and the space between the upper ends of the electrodes 33 and 33 is filled with water stored in the sealed portion 19.

  Here, the electrode part 6 may be either one in which an element constituting the electrode 33 is eluted as a sterilizing component by voltage application or one that generates a sterilizing component by oxidizing an element contained in water by voltage application. Be good. Specifically, as the electrode portion 6, one of the electrodes 33, 33 is used as an anode, the other electrode 33 is used as a cathode, and water stored in the sealed portion 19 by the electrode portion 6 by voltage application. It may be one that electrolyzes hypozinc acid, which is a bactericidal component, from the chlorine component contained in the electrode, and the electrode 33 serving as the anode is formed of silver or a metal containing silver to form a silver electrode, Silver that is a sterilizing component may be eluted in the sealed water portion 19.

  The lower ends of the electrodes 33 and 33 exposed to the outside of the trap body 12 are electrically connected to the control unit 7 via lead wires 41 as shown in FIG. , 33 is controlled by the control unit. In other words, the control unit 7 serves as a control unit that controls the operation of the electrode unit 6 and a charging unit that is charged by the hydroelectric generator 5 described above.

  Further, as shown in FIG. 2, the corner portion 34 formed by the bottom wall 24 and the peripheral wall 14 of the trap body 12 is curved in an arc shape protruding outward, and the upper end of the arc-shaped corner portion 34 is sealed. It is located above the lower end of the water bottle 13. It is assumed that the upper surface of the bottom wall 24 of the trap body 12 is formed so that all portions except the corner portion 34 and the electrode holding member 32 are a horizontal flat surface.

  In FIG. 2, reference numeral 35 denotes a net cage disposed in the upper part of the trap main body 12, and the net cage 35 is formed in a portion of the peripheral wall 14 of the trap main body 12 that is located above the stepped portion 27. An upper end flange portion 37 that is an upper end outer peripheral portion of the net cage 35 is placed on the placing step portion 36 so as to be detachably attached to the trap body 12. Further, reference numeral 38 in the figure denotes a filter for preventing small items such as a spoon from falling into the sealed water portion 19 and preventing the sealed water portion 19 from being seen from above. It attaches to the upper end part in the small diameter cylinder part 22 located above.

  When the sink 1 having the above configuration is used, the faucet 3 is opened by the operation handle shown in FIG. 1 provided in the faucet 3 so that the faucet 3 is in use. Thereby, the water flowing in the water supply pipe 4 flows into the water tank 2 from the water tap 3, and then flows from the water tank 2 to the drain trap 9 and the drain pipe 11 in this order and is discharged to the sewage side. Here, the drainage flowing into the drain trap 9 from the water tank 2 will be described in detail. This drainage flows into the sealing cylinder 13 from the upper end opening 20 of the sealing cylinder 13, and then into the gap B from the lower end opening 21 of the sealing cylinder 13. After flowing in, the downward flow is rectified to the flow on the outer peripheral side by the projecting surface 32 a of the electrode holding member 32, then flows along the bottom wall 24 of the trap body 12, and then flows to the outer peripheral side of the trap body 12. The water is rectified again at the corner portion 34 to become an upward flow, flows through the space A to the communication port portion 18 side, and flows out from the communication port portion 18 to the sewage side through the connection pipe portion 10. Thus, in this embodiment, since the sealing cylinder 13 and the trap body 12 are formed in a shape that does not hinder the flow of drainage, the drainage that has flowed into the drainage trap body 12 can flow smoothly to the sewage side. When the water tap 3 is opened, the hydroelectric generator 5 generates power using the water flow in the water supply pipe 4 to charge the control unit 7.

  Further, when the faucet 3 is closed by the operation handle 39 and the faucet 3 is not used, water is stored in the sealing portion 19 of the drain trap 9 and is stored in the sealing portion 19. The generated water prevents the sewage-side odor from being diffused to the water tank 2 side.

  As shown in FIG. 4, the electrode unit 6 provided in the drain trap 9 is configured to supply electric power charged in the control unit 7 when a predetermined time t <b> 1 elapses after the control unit 7 closes the water tap 3. And voltage application to the electrode unit 6 is automatically started, whereby the electrode unit 6 starts an electrolysis operation. Specifically, the control unit 7 starts counting the standby timer when the water tap 3 is closed from the open state. Here, the detection of opening and closing of the water tap 3 may be detected by, for example, a detecting means for detecting the rotation of the water turbine of the hydroelectric generator 5, and the open / close state of the water tap 3 provided in the water tap 3 may be detected. It may be performed by a detection means such as a sensor for detection, or may be performed by various conventionally known detection means. When the standby timer is turned off after a predetermined time t1 has elapsed since the start of the standby timer count, the control unit 7 automatically applies voltage to the electrode unit 6 using the power charged in the control unit 7. At the same time, the count of the OFF timer is started. When the voltage application to the electrode unit 6 is started, the electrode unit 6 starts an electrolysis operation, and the electrode unit 6 generates a sterilizing component in the sealed part 19 as described above. Odor generation can be suppressed. When the predetermined time t2 has elapsed after the voltage application to the electrode 6 is started and the OFF timer is turned off, the control unit 7 automatically stops the voltage application to the electrode unit 6, Thus, the electrolysis operation of the electrode unit 6 is stopped, and the generation of the sterilizing component is completed. When the water tap 3 is opened within a predetermined time t1 after the water tap 3 is closed (that is, during the standby timer counting), the control unit 7 causes the electrode unit 6 to be in contact with the electrode unit 6 even after the predetermined time t1 has elapsed. In other words, when the water tap 3 is opened during the standby timer count, the control unit 7 resets the standby timer and the water tap 3 is closed again. The count of the standby timer is started from this point, and the voltage application to the electrode unit 6 is started when the standby timer is turned off. Further, when the water tap 3 is opened while the voltage is being applied to the electrode unit 6 (that is, during the OFF timer counting), the voltage application to the electrode unit 6 is continued until the predetermined time t2 elapses (that is, the OFF timer is turned off). In this case, the application of the voltage to the electrode unit 6 may be stopped and the OFF timer may be reset at the same time.

  As described above, the power source of the electrode unit 6 is the hydroelectric generator 5 that generates power using the water flow when the water tap 3 is opened, so that voltage is applied to the electrode unit 6 without supplying electric power from the outside. And energy saving of the drainage equipment can be realized.

  Further, by disposing the electrode part 6 at a position facing the lower end opening 21 of the sealing cylinder 13 in the bottom wall 24 of the trap body 12 forming the sealing part 19, bubbles generated from the electrode part 6 during voltage application can be removed. It is possible to pull out from the lower end opening 21 of the sealing cylinder 13 to the drain outlet side, thereby suppressing the bubbles generated from the electrode part 6 from coming out above the space A on the downstream side of the sealing part 19, and as a result, the drain pipe It is possible to prevent the atmospheric pressure in 11 from increasing, and to further drain water smoothly.

  Further, for example, when a voltage is applied to the electrode unit 6 when the water tap 3 is opened, sterilizing components such as hypochlorous acid and silver ions in the sealing unit 19 generated by the electrode unit 6 flow out to the sewage side. As a result, there arises a problem that the effect of preventing the slimming and bad smell of the sealing portion 19 by the electrode portion 6 is reduced or the effect disappears. However, in the present embodiment, as described above, the water faucet 3 Since the application of the voltage to the electrode unit 6 is stopped when the plug is opened and the control unit 7 is charged by the hydroelectric generator 5 and the voltage is applied to the electrode unit 6 when the water tap 3 is closed, A voltage can be applied to the electrode part 6 only when water remains in the part 19, whereby it is possible to efficiently prevent slimming and offensive odors and prevent power shortage of the electrode part 6. Further, for example, when the electrode portion 6 having an anode as a silver electrode as described above is used, silver is eluted from the silver electrode along with the electrolysis operation of the electrode portion 6. In addition, since the electrolysis operation time of the electrode portion 6 can be reduced, the consumption of the silver electrode can be suppressed and the frequency of electrode replacement can be reduced.

  By the way, in the said embodiment, since the voltage application to the electrode part 6 is performed every time when the water tap 3 is used, the power shortage of the electrode part 6 may still occur or the electrode part 6 may be consumed. Therefore, an embodiment different from the above embodiment is shown in FIG. In the following, the same components as those in the above embodiment are given the same reference numerals, and the description overlapping with the above embodiment will be omitted.

That is, in the present embodiment, as shown in FIG. 5, the control unit 7 performs control to disable the voltage application to the electrode unit 6 until a predetermined time t4 elapses after the voltage application to the electrode unit 6 is completed. Yes. Specifically, the control unit 7 starts counting the voltage application impossibility timer when the application of the voltage to the electrode unit 6 is started in the above embodiment. Then, the count of the voltage application impossible timer advances, and when the application of the voltage to the electrode unit 6 is stopped after a predetermined time t2 has elapsed after the voltage application to the electrode unit 6 is started (that is, the OFF timer is turned off). At that time, the control unit 7 starts the control to disable the application of voltage to the electrode unit 6, and during the control to disable the voltage application, even if the water tap 3 is opened and then closed, The control in the above embodiment, that is, the control of automatically starting the voltage application to the electrode portion when the predetermined time t1 elapses after the water tap 3 is closed is not performed. Then, after the voltage application to the electrode section 6 is started, the predetermined time t3 (in this case, the predetermined time t3 is set longer than the predetermined time t2, that is, the predetermined time t4 is obtained by subtracting the predetermined time t2 from the predetermined time t3. When the voltage application impossibility timer is turned off after a predetermined value (t4 = t3-t2) has elapsed, the control unit 7 stops the control to disable the application of voltage to the electrode unit 6, and the electrode Control to enable voltage application to the unit 6 is performed. During the control enabling the voltage application, as shown in FIG. 5A, when the water faucet 3 is opened and then closed, a predetermined time t1 has elapsed after the water faucet 3 is closed as described above. At the time, control for automatically starting the voltage application to the electrode unit 6 is performed, and thereafter, the same control as described above is repeatedly performed. As shown in FIG. 5B, when the water tap 3 is in the open state when the predetermined time t4 has elapsed (that is, when the voltage application disable timer is turned off), the control unit 7 It is assumed that control for automatically starting the application of voltage to the electrode unit 6 is performed when a predetermined time t1 has elapsed after closing the water supply tap 3 in the plugged state, and the same control as described above is performed. In the present embodiment, the time when the predetermined time t4 has elapsed is detected by turning off the voltage application disable timer which starts counting from the time when voltage application to the electrode unit 6 is started and turns OFF at the predetermined time t3. The counting may be started from the point of time when the application of the voltage to the electrode unit 6 is completed, and the detection may be performed by turning off a voltage application impossible timer that is turned off at a predetermined time t4.

  As described above, the control unit 7 performs the control to disable the voltage application to the electrode unit 6 within a predetermined time t4 from the time when the application of the voltage to the electrode unit 6 is completed, so Further, in this case, when the water tap 3 is opened during the predetermined time t4, the control unit 7 can be charged by the hydroelectric generator 5, and thereby the power of the electrode unit 6 is insufficient. Can be further prevented. Further, in this case, since the electrolysis operation time of the electrode part 6 can be further shortened as compared with the above-described embodiment, when the electrode part 6 having a silver electrode as described above is used, The consumption of the electrode can be further suppressed.

  In the above-described embodiment, the home piping facility is the kitchen sink 1 and the water tank 2 is supplied with water from the water tap 3. However, the present invention is not limited to this. For example, the home piping facility For example, it may be a wash basin, a toilet, a bathroom, or the like, or a water supply from the faucet 3 may be a floor such as a bathroom floor pan.
