  In the following description, the direction (lower left direction in FIG. 1) from the functional unit 30 to the toilet lid 113 is defined as the front direction, the opposite direction is defined as the rear direction, and these are defined as the front and rear directions. Further, the direction from the toilet body 11 toward the toilet lid 113 (upward direction in FIG. 1) is defined as the upward direction, the opposite direction is defined as the downward direction, and these are defined as the vertical direction. Further, the left direction (lower left direction in FIG. 1) in the backward direction is defined as the left direction, the opposite direction is defined as the right direction, and these are defined as the left and right directions.

  The local cleaning mechanism 50 includes a local cleaning unit 51 disposed at the rear of the toilet bowl 111 and having a nozzle 511, hoses 561, 564, and 569 constituting a cleaning water flow path, an air gap 52, a water supply valve 551, and an assist. And a pump 523. A water supply valve 551 as a water supply valve is connected to the water supply, and switches between permitting and shutting off the inflow of tap water from the water supply to the hose constituting the washing water flow path. One end portion of a hose 561 is connected to the water supply valve 551, and the other end portion of the hose 561 is connected to an upper end portion of an upward extending member 565 extending upward from the rear portion of the air gap 52. The lower end portion of the upward extending member 565 is connected to the rear portion of the air gap 52. Therefore, the tap water that has flowed into the hose 561 via the water supply valve 551 is configured to flow into the internal space of the rear portion of the air gap 52 through the upward extending member 565.

  The air gap 52 is disposed at the left end in the functional unit 30 and in the vicinity of the left side surface of the functional unit 30, and as shown in FIGS. It has a groove-shaped lower portion 521 and an upper lid portion 522 that closes the opening. The groove-shaped lower part 521 and the upper lid part 522 extend forward from the upwardly extending part and extend to the front wall of the local cleaning mechanism part 50. As shown in FIG. 7, the bottom 5211 of the groove-shaped lower part 521 has an inclined surface that becomes lower as it goes forward. As a result, the cleaning water and descaling agent that have flowed into the air gap 52 move from the upper side (left side in FIG. 7) to the lower side (right side in FIG. 7) of the bottom 5211 of the groove-like lower part 521 in the air gap 52. In other words, the air gap 52 is configured to flow from the rear part toward the front part.

  As shown in FIG. 4, a through hole 5221 that opens upward in a rectangular shape is formed in the upper lid portion 522 of the air gap 52. The through hole 5221 communicates the internal space of the air gap 52 and the external space of the air gap 52, and opens the cleaning water flow path constituted by the internal space of the air gap 52 to the atmosphere. In addition, the front end portion of the groove-shaped lower portion 521 opens toward the front in an opening portion 302 formed in the front wall portion 301 located on the front side of the local cleaning mechanism portion 50. As shown in FIG. 4, the front end portion 5224 of the upper lid portion 522 is located on the rear side of the front end portion 5214 of the groove-like lower portion 521. Thereby, in the front end part of the air gap 52, only the groove-shaped lower part 521 which opens toward the upper direction where the upper cover part 522 does not exist exists.

  In addition, the other end of the hose 566 is connected to the upper lid 522 of the air gap 52, and the other end of the hose 566 is a tube member as an injection member for injecting the descaling agent as shown in FIG. It is connected to the connection member 311 which comprises the connection port for connecting the hose which is. Accordingly, the inflow position (one end portion 5661 of the hose 566) where the descaling agent flows into the cleaning water flow path through the air gap 52 is more than the water supply position (the other end section 5641 of the hose 564) where the cleaning water is supplied to the cleaning water flow path. It is a downstream side of the washing water channel. In other words, the inflow position (one end portion 5661 of the hose 566) where the descaling agent flows into the cleaning water flow path through the air gap 52 is the water supply position (the other end section 5641 of the hose 564) where the cleaning water is supplied to the cleaning water flow path. The front side is a lower position than the assist pump 523 for allowing the cleaning water to flow through the cleaning water channel. Further, the connection member 311 is positioned above a portion where one end portion 5661 of the hose 566 is connected to the upper lid portion 522 of the air gap 52. Thereby, it is possible to prevent the descaling agent from dripping from the connection member 311.

  As shown in FIGS. 2, 3A, and 3B, the connection member 311 having a connection port for connecting a hose for injecting the descaling agent is located on the side surface of the functional unit 30, so that It is arranged on the side surface of the functional unit 30. More specifically, as shown in FIG. 2, the side surface of the functional unit 30 is a side surface of the functional unit 30, and is a front side portion 101 of the toilet device 1 constituted by the toilet seat device 100 and the toilet body 11. The rear portion of the side surface located rearward of the front end 1021 of the rear portion 102 in plan view, that is, the side surface of the rear portion 101 that is curved as the front portion 101 advances rearward. Means that it is visible when viewed from directly behind the toilet, but when viewed from the front of the toilet, it is hidden by the left and right ends of the toilet and cannot be seen. To do.

  As shown in FIG. 7, the bottom 5211 of the groove-shaped lower part 521 has a connection part 5213 having an opening. The connection portion 5213 is located below the through hole 5221 of the upper lid portion 522. One end portion 5671 of the hose 567 is connected to the downstream side (the right side in FIG. 7) in the air flow direction in the air gap 52 from the through hole 5221 of the upper lid portion 522. The other end of the hose 567 is connected to the connection member 562.

  As shown in FIG. 6, the connecting portion 5213 of the bottom portion 5211 of the groove-shaped lower portion 521 of the air gap 52 is connected to the relay member 568. One end of a hose 569 is connected to the relay member 568. The other end of the hose 569 is provided in a ceramic heater (not shown) for warming the cleaning water, and a portion of the cleaning water channel disposed in the vicinity of the ceramic heater, and can detect the flow rate of the cleaning water flowing through the cleaning water channel. It is connected to the assist pump 523 via a flow rate sensor 571 (see FIG. 8). The assist pump 523 communicates with a nozzle 511 of the local cleaning unit 51 (FIG. 2). When the assist pump 523 is driven, the cleaning water is circulated through the cleaning water flow path in the local cleaning mechanism unit 50. The hose 561, the hose 564, the upward extending member 565, the internal space of the air gap 52, the relay member 568, and the hose 569 constitute a washing water flow path.

  As shown in FIG. 2, the descaling agent is stored in a container 114 that constitutes the descaling agent supply unit. One end of a hose 115 constituting a descaling agent supply unit is connected to the mouth of the container 114, and the mouth of the container 114 is connected to the front end of the toilet lid 113 (in FIG. 2) via the container holding unit 116. It is supported by the uppermost part of the toilet lid 113). With this positional relationship, it is possible to supply the descaling agent in the container 114 to the washing water flow path using the water head pressure. The container holding part 116 has a hook-like part 1161 formed in a U-shape and a C-shaped plate-like container support part 1162 integrally connected to the hook-like part 1161. The hook-like portion 1161 is locked to the front end portion of the opened toilet lid 113, and the mouth portion of the container 114 is supported at the central portion of the C-shaped container support portion 1162. It is supported by the toilet lid 113.

  The other end of the hose 115 is connected to an end connection member 1171 having a connection port for connecting the hose 115 for injecting the descaling agent. The end connecting member 1171 constitutes a descaling agent supply unit, and is configured by a tube member that is bent in an L shape. The inner diameter of the end connecting member 1171 is smaller than the inner diameter of any part of the hose 115. A plurality of types of end connection members 1171 having different inner diameters are prepared in advance, and the end connection member 1171 is appropriately selected and used based on the flow rate of the descaling agent to be circulated through the wash water flow path. That is, the flow rate of the descaling agent to be circulated can be adjusted by selecting and using the end connecting member 1171 having an appropriate inner diameter. A rubber O-ring (not shown) is provided on the peripheral surface in the vicinity of the distal end portion of the end connection member 1171, and the end connection member 1171 is press-fitted into and connected to the opening of the connection member 311.

  In the middle of the hose 115, a valve 1172 for switching between the flow and blocking of the descaling agent in the hose 115 is provided. By opening the valve 1172, the descaling agent flows from the container 114 through the hose 115, flows through the hose 566 through the connection member 311, and flows into the internal space of the air gap 52. By closing the valve 1172, the flow of the descaling agent from the container 114 flowing through the hose 115 is blocked.

  The control unit 33 includes a control circuit board housed in the function unit 30. As shown in FIG. 8, the control unit 33 includes a toilet lid driving unit 322, an assist pump 523, a water supply valve 551, and a flow rate sensor 571. It is configured to be electrically connected to perform these controls. Further, the control unit 33 communicates with a remote controller (not shown) fixed to the wall surface of the toilet by wireless communication, so that various operations such as discharge of cleaning water from the nozzles 511 of the local cleaning unit 51 are performed by operations from the remote controller. Take control.

  The container 114, the container holding part 116, the hose 115, the end connection member 1171, the valve 1172, the assist pump 523, the flow rate sensor 571, the water supply valve 551, and the control part 33 constitute a descale agent supply device. Moreover, the container 114, the container holding part 116, the hose 115, the end connection member 1171, and the valve 1172 constitute a descaling agent supply part.

  Next, the control by the control unit 33, which removes the scale accumulated in the nozzle 511 and the cleaning water channel of the local cleaning unit 51 by causing the descaling agent to flow through the cleaning water channel, will be described with reference to FIG. 9 and FIG. . FIG. 9 is a time chart showing control for supplying the descaling agent to the washing water flow path and the nozzle 511 of the toilet seat device 100. FIG. 10 is a time chart showing the control for discharging the descaling agent from the washing water flow path and the nozzle 511 of the toilet seat device 100.

  First, when the user of the toilet seat device 100 operates a descale button of a remote controller (not shown) to remove the scale, the control unit 33 maintains the state in which the toilet lid 113 is open with respect to the toilet lid driving unit 322. Control. That is, the controller 33 drives the toilet lid so that the toilet lid 113 is not closed when the descaling agent is supplied from the container 114 to the washing water flow path, and the open state as shown in FIG. 2 is maintained. The unit 322 is controlled.

  Moreover, the control part 33 performs control which maintains the state which the water supply valve 551 closed with respect to the water supply valve 551, as shown in FIG. At the same time, the control unit 33 controls the assist pump 523 to drive the assist pump 523 and controls the flow rate sensor 571 to monitor (detect) the flow rate. In the control for the flow rate sensor 571, the detection is continuously performed until the elapse of 5 seconds from the start of the control, and the cleaning water that has entered the cleaning water flow channel flows out, and the descaling agent flows in instead. After the elapse of 5 seconds considered to have occurred, the flow rate sensor 571 determines that the flow rate in the washing water channel is equal to or greater than a predetermined value every second, that is, once per second. If is not greater than or equal to the predetermined value, it is determined that normal descaling agent filling has not been performed, and the process proceeds to control for discharging the descaling agent shown in FIG. The controller 33 assists the assist pump 523 at the time when 10 seconds have passed since the start of the control, which is considered that the descaling agent is filled in the nozzle 511 and the portion of the washing water flow path connected to the nozzle. Control for stopping the driving of the pump 523 is performed, and control for terminating the flow rate monitoring (detection) is performed for the flow rate sensor 571.

  As a result, the descaling agent is spread and filled in the nozzle 511 and the cleaning water flow path of the local cleaning unit 51. By maintaining this state for a predetermined period of time, the scale that has adhered and accumulated in the nozzle 511 and the cleaning water flow path of the local cleaning unit 51 is removed by the descaling agent.

  Next, as shown in FIG. 10, the control unit 33 performs control for maintaining the water supply valve 551 in a state where the water supply valve 551 is open for one minute. At the same time, the control unit 33 controls the assist pump 523 to drive the assist pump 523, and the control unit 33 continuously monitors (detects) the flow rate with respect to the flow rate sensor 571 for one minute. Control to be performed. And 1 minute after starting control, the control part 33 performs control which maintains the state which the water supply valve 551 closed with respect to the water supply valve 551 for 5 second. At the same time, the flow rate of the flow rate sensor 571 was the predetermined amount immediately before that, that is, the flow rate was stopped from the state where the water supply valve 551 was operating, and the previous flow rate was equal to or higher than the predetermined value. Then, control is performed so that the flow rate is not determined for 5 seconds. And the control part 33 performs control which repeats this 1-minute control 4 times on both sides of the control for 5 seconds.

  Since all the water circuits constituted by the nozzle 511 and the washing water flow path are not uniform in inner diameter, if water continues to flow, a liquid pool is formed at a predetermined portion in the water circuit and cannot be completely drained. However, as described above, the control unit 33 can repeatedly perform the water circuit once empty by performing the control for 1 minute and the control for 5 seconds. From the nozzle 511 and the washing water flow path, the descaling agent that has been in a state of being spread and filled flows out from the nozzle 511 of the local washing unit 51 to the toilet bowl 111 together with the scale and washing water, and the nozzle of the local washing unit 51 No descaling agent remains in 511 and the washing water flow path.

According to the toilet seat device 100 according to the embodiment having the above-described configuration, the following effects can be obtained.
The local cleaning mechanism unit 50 of the toilet seat apparatus 100 including the toilet unit 10 having the toilet bowl 111, the local cleaning mechanism unit 50 having a cleaning function, and the functional unit 30 disposed behind the toilet unit 10 includes cleaning water. The cleaning water channel is formed with an air gap 52 that opens the cleaning water channel to the atmosphere, and a descaling agent for removing scale accumulated in the cleaning water channel is injected into the air gap 52. A hose 115 can be connected.

  With this configuration, there is no need to provide a dedicated tank for storing the descaling agent in the functional unit 30, so that the degree of freedom of layout of each member in the functional unit 30 can be increased. Moreover, since it is only necessary to form an opening to which the hose 115 as a pipe member for injecting the descaling agent can be connected, it is not necessary to enlarge the opening, and it is possible to suppress a decrease in designability. . Further, since the flow rate at the end connection member 1171 can be adjusted by adjusting the inner diameter of the end connection member 1171, the flow rate can be easily adjusted at the design stage.

  Further, the inflow position (one end portion 5661 of the hose 566) where the descaling agent flows into the cleaning water passage through the air gap 52 is more than the water supply position (the other end portion 5641 of the hose 564) where the cleaning water is supplied to the cleaning water passage. It is a downstream side of the washing water channel. Further, the inflow position (one end portion 5661 of the hose 566) where the descaling agent flows into the cleaning water flow path through the air gap 52 is more than the water supply position (the other end section 5641 of the hose 564) where the cleaning water is supplied to the cleaning water flow path. It is a low position.

  With this configuration, it is possible to prevent a part of the descaling agent jumped up when the descaling agent flows into the cleaning water flow path from being attached to the water supply position where the cleaning water is supplied to the cleaning water flow path.

  Further, the inflow position (one end portion 5661 of the hose 566) where the descaling agent flows into the cleaning water flow path through the air gap 52 is upstream of the cleaning water flow path from the assist pump 523 for circulating the cleaning water through the cleaning water flow path. is there. With this configuration, by driving the assist pump 523, it is possible to distribute the descaling agent through the nozzle 511 and the washing water flow path.

Further, the end connection member 1171 constituting the downstream end of the descaling agent supply pipe through which the descaling agent flows to the air gap 52 is configured to be the narrowest in the hose 115 serving as the supply pipe.
With this configuration, by reducing the diameter of the final inlet to the air gap 52, it is possible to cause a siphon phenomenon and prevent dripping to the outside. Further, by selecting an appropriate inner diameter as the diameter of the final inlet to the air gap 52, it is possible to adjust the flow rate of the descaling agent to be circulated through the nozzle 511 and the washing water flow path.

  Further, the side surface of the functional unit 30 of the toilet seat apparatus 100 is connected to a hose 115 as an injection member for injecting a descaling agent for removing scales accumulated in the cleaning water flow path in which the cleaning water flows in the local cleaning mechanism unit 50. A connection member 311 having a possible connection port is included. With this configuration, since the connection port is in a position that cannot be seen during normal use of the toilet seat apparatus 100, it is possible to prevent the designability of the toilet seat apparatus 100 from being impaired. Moreover, it is possible to prevent water from flowing in from the connection port when the toilet part 10 is washed with water from the front side of the toilet part 10.

  The injection member is a hose 115 which is a pipe member. With this configuration, it is only necessary that the connection port has a size that can connect the hose 115, which is a thin tube member, so that the connection port can be made smaller and the design of the toilet seat device 100 can be impaired. It can be surely prevented.

  Further, the end of the hose 115 to which the O-ring is attached is press-fitted and connected to the connection member 311 having a connection port. With this configuration, the connection member 311 having a connection port can be configured simply and a small connection port can be configured. For this reason, it becomes possible to prevent more reliably that the designability of the toilet seat apparatus 100 is impaired.

  Further, the descaling agent supply device provided in the toilet seat apparatus 100 includes a container 114 in which the descaling agent for removing scales accumulated in the washing water flow path in which the washing water flows in the local washing mechanism unit 50 is stored, and the toilet seat apparatus 100. And a container holding part 116 for holding the container 114.

With this configuration, the container 114 and the container holding part 116 for supplying the descaling agent are retrofitted parts to the toilet seat device 100, and therefore, the design of the toilet seat device 100 during normal use of the toilet seat device 100 is prevented from being impaired. Is possible.
