JP 2008-174944 A

  However, in the toilet bowl cleaning device of Patent Document 1, when a power failure occurs during toilet bowl cleaning, the wash water supplied to the toilet bowl after that is for sealing the sealing portion of the toilet bowl body, It is no longer the supply of cleaning water to carry out. For this reason, toilet bowl cleaning is not performed completely, and there is a possibility that discharge of filth and the like will be insufficient.

  The present invention has been made in view of the above-mentioned conventional situation, and provides a toilet cleaning device that can complete toilet cleaning and reliably discharge filth and the like even if a power failure occurs during toilet cleaning. This is a problem to be solved.

The toilet bowl cleaning device of the present invention is an toilet bowl cleaning apparatus including an electrically driven water supply device that supplies cleaning water to the toilet body, and a power supply device that has a power supply path that supplies power to the water supply device,
The power supply device includes a power storage device connected in series to the power supply path.

  In this toilet bowl cleaning device, since the power is supplied to the water feeding device via the power storage device connected in series to the power supply path, the power storage device can always maintain a fully charged state. For this reason, since the water supply device can supply power to the water supply device from the power storage device even if a power failure occurs while the water supply device supplies cleaning water to the toilet body and performs toilet cleaning, the toilet cleaning device Can complete toilet flush as usual.

  Therefore, the toilet bowl cleaning device of the present invention can complete toilet flushing and reliably discharge filth and the like even if a power failure occurs during toilet bowl cleaning.

  The power storage device can store power that allows the water supply device to perform one toilet flush. The toilet flushing device only has to store the electric power that can complete the toilet flushing as usual when a power failure occurs during the toilet flushing. It is sufficient to be able to carry out toilet cleaning. Thus, miniaturization of the power storage device can be achieved by minimizing the capacity of the power storage device.

  The power supply apparatus has a branch power supply path that branches the power supply path and supplies electric power to an electric device that is used for purposes other than cleaning the toilet provided in the toilet body. When a power failure occurs, the power supply apparatus The power supply to the branch power supply path can be stopped, and the power stored in the power storage device can be supplied only to the power supply path. In this case, since power supply to the branch power supply path is stopped when a power failure occurs, the power stored in the power storage device is not used except for the toilet bowl cleaning device. In other words, since the stored power is not consumed by electrical equipment other than the water transmission device, the power storage device can reliably secure power for completing toilet flushing in the event of a power failure. Can be driven.

It is a block diagram which shows the flush toilet bowl of Example 1. FIG. It is a block diagram which shows the principal parts, such as a power supply device of Example 1. FIG. It is a block diagram which shows the flush toilet bowl of Example 2. FIG.

  Embodiments 1 and 2 embodying a flush toilet equipped with the toilet cleaning device of the present invention will be described with reference to the drawings.

<Example 1>
As shown in FIG. 1, the flush toilet of Example 1 includes a toilet body 10 and a toilet cleaning device 20. The toilet body 10 includes a toilet bowl 11 and a toilet drainage channel 12 communicating with the downstream side of the toilet bowl 11. The toilet body 10 has a toilet seat device 13 attached to the upper surface. The toilet seat device 13 includes a toilet seat box 14 attached to the rear upper surface of the toilet body 10, and a toilet lid 15 and a toilet seat 16 that are rotatably attached to the toilet seat box 14. The toilet seat device 13 houses an electrical device 17 such as a local cleaning device 17A and a deodorizing device 17B and a control device 18 for controlling them in a toilet seat box 14.

  The toilet bowl cleaning device 20 includes a cleaning tank 21 that stores cleaning water, a water supply path 22 that connects the cleaning tank 21 and the toilet body 10, and cleaning water stored in the cleaning tank 21 via the water supply path 22. And a power supply device 25 having a power supply path 24 for supplying electric power to the pump 23.

  The washing tank 21 is installed behind the toilet body 10. For this reason, the flush toilet bowl can realize a low silhouette. The cleaning tank 21 has an upstream end of the water supply path 22 connected to the lower part of the side surface. The water supply path 22 connects the downstream end to the rear part of the toilet bowl 11 of the toilet body 10. The wash water discharged from the downstream end of the water supply channel 22 flows down to the surface of the toilet bowl 11 while flowing in one direction along the rim water passage provided on the upper peripheral edge of the toilet bowl 11. For this reason, the wash water forms a swirl flow that flows into the toilet drainage channel 12 while swirling the surface of the toilet bowl 11.

  The pump 23 is provided in the middle of the water supply path 22. A pump control device 26 is disposed in the power supply path 24 between the power supply device 25 and the pump 23. The pump control device 26 can control the start and stop of the operation of the pump 23 and the change of the rotation speed. For this reason, the toilet bowl washing | cleaning apparatus 20 can change the water quantity and flow volume (water feeding quantity of fixed time) of the washing water sent to the toilet bowl main body 10. FIG. Therefore, the toilet bowl cleaning device 20 can execute the large cleaning mode with a large amount of cleaning water by increasing the number of rotations of the pump 23 and supplying a large amount of cleaning water to the toilet body 10 for a set time. Further, the toilet flushing device 20 reduces the amount of flushing water by reducing the number of rotations of the pump 23 compared to the large flushing mode and sending a small flow rate of flushing water to the toilet bowl body 10 for a shorter time than the large flushing mode. A small washing mode can be performed. As described above, the toilet bowl cleaning device 20 can execute at least two types of toilet bowl cleaning in the large cleaning mode and the small cleaning mode.

  As shown in FIGS. 1 and 2, the power supply device 25 includes a lithium ion secondary battery 28 that is a power storage device connected to a power cord 27 having a power outlet 27 </ b> A that is a part of the power supply path 24 at the tip, and a lithium ion battery. And a voltage divider 29 connected to the secondary battery 28. As described above, the power supply path 24 is connected to the pump 23 from the voltage divider 29 of the power supply device 25 via the pump control device 26. As described above, the lithium ion secondary battery 28, the voltage divider 29, and the pump control device 26 are connected in series to the power supply path 24 that supplies power to the pump 23 (the power supply path 24 from the power outlet 27A to the pump 23). Are arranged. The lithium ion secondary battery 28 can store electric power that allows the pump 23 to execute one toilet cleaning in the large cleaning mode.

  The distributor 29 is connected to a branch power supply path 29A that supplies power to the electric devices 17 via a control device 18 that controls the electric devices 17 such as the local cleaning device 17A and the deodorizing device 17B. Further, as shown in FIG. 2, the power distributor 29 has a control device 29B that detects a power failure and switches the branch power supply path 29A from the energized state to the non-energized state. For this reason, when a power failure occurs, the power distributor 29 stops the power supply to the branch power supply path 29 </ b> A, and supplies the power stored in the lithium ion secondary battery 28 only to the power supply path 24.

  In the flush toilet having such a configuration, since the lithium ion secondary battery 28 of the power supply device 25 is connected in series to the power supply path 24, the lithium ion secondary battery 28 always maintains a fully charged state. be able to. For this reason, even if the toilet flushing device 20 is in the middle of executing the toilet flushing, even if a power failure occurs, power can be reliably supplied from the lithium ion secondary battery 28 to the pump 23. You can complete the same toilet flushing.

  Therefore, the flush toilet equipped with the toilet cleaning device 20 of the first embodiment can complete the toilet cleaning and reliably discharge filth and the like even if a power failure occurs during toilet cleaning.

  In addition, the lithium ion secondary battery 28 has a minimum electric power that can reliably complete the toilet flushing even if a power failure occurs during the toilet flushing, that is, one toilet bowl in the large washing mode. Since it is only necessary to store electric power for performing the cleaning, the size can be reduced.

  Furthermore, since power supply to the branch feeding path 29A is stopped when a power failure occurs, the power stored in the lithium ion secondary battery 28 is not used other than driving the pump 23 (toilet bowl cleaning). In other words, since the electric power stored in the lithium ion secondary battery 28 is not consumed by the electric equipment 17 used for purposes other than toilet cleaning such as the local cleaning device 17B, it is possible to reliably secure power for completing the toilet cleaning in the event of a power failure. The pump 23 can be driven in the same manner as normal toilet flushing.

<Example 2>
As shown in FIG. 3, the flush toilet of Example 2 has a point that the toilet bowl cleaning device 30 does not have a cleaning tank, and the water supply device 31 directly uses the water supply pressure of the water supply source. Along with the rim water supply path 32 </ b> A that discharges the cleaning water along the rim water passage provided along the upper rim of the toilet bowl 11, and the toilet drainage path 12. Thus, the second embodiment is different from the first embodiment in that it has a jet water supply path 32B that discharges cleaning water toward the downstream side. The same configurations as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The water supply device 31 of the toilet bowl cleaning device 30 communicates with the water supply hose 33 on the upstream side. The water supply hose 33 has an upstream end connected to a water supply pipe (not shown) communicating with a water supply source drawn into the toilet room where the toilet body 10 is installed.

  The water feeding device 31 has a stop cock 34, a rim on-off valve 35A, and a jet on-off valve 35B. The stop cock 34 is provided in the upstream water supply channel 35 </ b> C to which the downstream end of the water supply hose 33 is connected. The upstream water supply channel 35C branches into a rim water supply channel 32A and a jet water supply channel 32B at the downstream end. The rim opening / closing valve 35A is provided in the rim water supply passage 32A. The jet opening / closing valve 35B is provided in the jet water supply path 32B.

  The downstream end of the rim water supply channel 32 </ b> A is connected to the rear part of the toilet bowl 11 of the toilet body 10. The wash water discharged from the downstream end of the rim water supply channel 32 </ b> A flows down to the surface of the toilet bowl 11 while flowing in one direction along the rim water passage provided on the upper peripheral edge of the toilet bowl 11. For this reason, the wash water forms a swirl flow that flows into the toilet drainage channel 12 while swirling the surface of the toilet bowl 11.

  The jet water supply path 32 </ b> B is connected to the lower part of the toilet bowl 11 of the toilet body 10. The wash water discharged from the downstream end of the jet water supply channel 32B flows along the toilet drainage channel 12 toward the downstream side. Since washing water is directly supplied to the toilet drainage channel 12 from the jet water supply channel 32 </ b> B, a siphon action can be efficiently generated in the toilet drainage channel 12.

  The power supply device 25 has a power supply path 24 that supplies electric power to the rim on-off valve 35A and the jet on-off valve 35B. An on-off valve controller 26A is disposed in the power supply path 24 between the power supply device 25 and the rim on-off valve 35A and jet on-off valve 35B. The on / off valve control device 26A can control the opening / closing of the rim on / off valve 35A and the jet on / off valve 35B. For this reason, the toilet bowl cleaning device 30 first performs rim cleaning in which the rim opening / closing valve 35A is opened to discharge cleaning water to the rim water passage through the rim water supply passage 32A, and then the rim opening / closing valve 35A. And the jet opening / closing valve 35B is opened, jet cleaning is performed to discharge flush water to the toilet drainage passage 12 through the jet water supply path 32B, and then the jet opening / closing valve 35B is closed. The rim on / off valve 35A is opened again for a set time, and the toilet cleaning can be executed to execute the rim cleaning. Moreover, the toilet bowl washing | cleaning apparatus 30 can change the rim washing | cleaning time and jet washing | cleaning time, and can perform the large washing mode with many amounts of washing water, and the small washing mode with little amount of washing water. As described above, the toilet bowl cleaning device 30 can execute at least two types of toilet bowl cleaning in the large cleaning mode and the small cleaning mode.

  The lithium ion secondary battery 28 of the power supply device 25 opens and closes the rim on-off valve 35A and the jet on-off valve 35B of the water supply device 31 to perform one toilet cleaning, that is, rim cleaning, jet cleaning, and rim cleaning. It is possible to store electric power to be executed in order. In this way, the minimum necessary power that can reliably complete the toilet flushing even if a power failure occurs during the toilet flushing, that is, the electric power necessary to perform one toilet flush is stored. Therefore, the lithium ion secondary battery 28 can be downsized.

  In the flush toilet having such a configuration, since the lithium ion secondary battery 28 of the power supply device 25 is connected in series to the power supply path 24, the lithium ion secondary battery 28 always maintains a fully charged state. be able to. For this reason, even when the toilet flushing device 30 is in the middle of executing toilet flushing, power can be reliably supplied from the lithium ion secondary battery 28 to the rim on-off valve 35A and the jet on-off valve 35B. Therefore, the toilet bowl cleaning device 30 can complete the same toilet cleaning as usual.

  Therefore, the flush toilet equipped with the toilet cleaning device 30 of the second embodiment can complete the toilet cleaning and reliably discharge filth and the like even if a power failure occurs during toilet cleaning.
