[0009] Hereinafter, preferred embodiments of the cleansing toilet seat device of the present invention will be described with reference to the accompanying drawings. Note that common parts will be designated by common reference numerals throughout these drawings.

[0010] 1 to 9 show a cleaning toilet seat device 10 according to one embodiment of the present invention. FIG. 1 shows an example of the configuration of the cleaning toilet seat device 10 installed around a toilet bowl 1 in a toilet room S. FIG. 2 is a perspective view of the main body 11, toilet seat 12, and toilet seat cover 13 of the cleaning toilet seat device 10, viewed from the bottom. The toilet bowl 1 has a concave bowl portion 2 with an open upper surface that receives excrement, and this bowl portion 2 forms the inner surface of the toilet bowl 1. The bowl portion 2 is the toilet bowl of the toilet bowl 1. The toilet seat 12 in this embodiment is approximately O-shaped in plan view, and the toilet seat cover 13 covers the toilet seat 12 and is shaped so that a central opening 12A of the toilet seat 12 can be opened and closed. The main body 11 of the cleaning toilet seat device 10 is installed above the toilet bowl 1.

[0011] The main body 11 is provided with a hollow casing 15 which is the main body part, and this casing 15 is made up of an outer shell member made of synthetic resin, consisting of a main body underside 16 which is attached and fixed to the upper surface of the rear part 3 of the toilet 1, and a casing upper part 17 which covers the upper surface of the main body underside 16 and has an open bottom. A toilet seat 12 and toilet seat lid 13, both made of synthetic resin, are rotatably attached to the casing 15, and the toilet seat lid 13 has a central opening 12A which can be opened and closed freely, so that with the toilet seat lid 13 open, as shown in Figure 1, the user can sit on the toilet seat 12 with their buttocks resting on it by tilting the toilet seat 12 towards the toilet 1.

[0012] On the underside of the toilet seat 12, multiple convex seat legs 18 are arranged at intervals, which come into direct contact with the top surface of the toilet bowl 1 when the toilet seat 12 is tilted toward the toilet bowl 1, which is the in-use position, and in this example, are located in four places: on the left and right front sides and on the left and right rear sides. One of the seat legs 18 has a built-in mechanical seat switch 19 that serves as seat occupancy detection means, and it can detect whether or not the user is seated on the toilet seat 12 based on whether or not the seat switch 19 is pressed when the seat leg 18 comes into contact with the toilet bowl 1. The seat switch 19 is located on one of the seat legs 18 on the left or right front side in the center, and is seat occupancy detection means that detects whether or not the user is sitting on the toilet seat 12.

[0013] Reference numeral 21 denotes a main body operation unit made of synthetic resin and provided on the side of the casing 15. As will be described later, the main body operation unit 21 is provided with various operation buttons including, for example, flushing buttons such as a butt button and a bidet button, and a stop button for stopping the spray of flushing water, and user operations are input via these operation buttons. The main body operation unit 21 is also provided with a main body display unit 22 including indicator lamps such as a water pressure adjustment lamp, a hot water temperature adjustment lamp, a toilet seat temperature adjustment lamp, a deodorization lamp, and a power saving lamp, and the display forms of these indicator lamps inform the user of the operating status of each part of the washing toilet seat device 10.

[0014] The cleansing toilet seat device 10 is equipped with a so-called movable cleaning nozzle 25, which sprays water toward the private parts of a user seated on the toilet seat 12, at the lower front of the casing 15. The cleaning nozzle 25, which corresponds to a nozzle device, is cylindrical and extends linearly along the front-to-rear direction of the main body 11, and is arranged to be able to move back and forth along the front-to-rear direction of the main body 11. One or more nozzles (not shown) are provided around the peripheral surface of the tip of the cleaning nozzle 25 so that cleaning liquid is efficiently sprayed toward the private parts of a user seated on the toilet seat 12 when the cleaning nozzle 25 is advanced to a position protruding from below the toilet seat 12. In addition, a nozzle guard 26, which protrudes downward from the main body 11, is integrally formed on the main body underside 16, which forms the bottom of the casing 15, to protect the cleaning nozzle 25 housed within the casing 15 when the cleaning nozzle 25 is retracted to a position below the toilet seat 12. The cleaning nozzle 25 is preferably made of stainless steel to maintain cleanliness, but other materials may be used. Although neither is shown in the present embodiment, the washing nozzle 25 is made up of a rear washing nozzle that sprays cleansing liquid onto a first private part of the user and a bidet washing nozzle that sprays cleansing liquid onto a second private part different from the first private part of the user. The rear washing nozzle and the bidet washing nozzle are movable along the same axis or separate axes.

[0015] To supply tap water to the flushing nozzle 25, a water stop device 33 (see FIG. 4) is provided on the rear side of the casing 15. The water stop mechanism 33 starts and stops the flow of water from the main water inlet 31 to the flushing nozzle 25 (not shown). In this embodiment, the water stop mechanism 33 is configured as an electromagnetic valve and can be turned on and off by an electrical signal. The above-mentioned water inlet and the main water inlet 31 are connected by a water supply hose 32. In this embodiment, a pump 34 is provided in the flow path between the water stop mechanism 33 and the flushing nozzle 25 to pressurize the water, allowing the pressure of the water sprayed from the flushing nozzle 25 to be adjusted. Note that this is just one example, and the pump 34 may be omitted.

[0016] A deodorizing device 41 is built into the casing 15 to reduce and remove odors within the toilet bowl 1. The deodorizing device 41 is configured by disposing a deodorizing filter 44 and a deodorizing fan (not shown) in a deodorizing passage (not shown) between an intake port 42 provided at the front bottom of the casing 15 facing the top surface of the toilet bowl 1, and an exhaust port 43 provided at the rear of the casing 15. The deodorizing filter 44 is detachably provided inside the casing 15 facing the exhaust port 43, and can be replaced with a new deodorizing filter 44 as needed. The deodorizing fan is disposed between the exhaust port 43 and the deodorizing filter 44, and while the deodorizing fan is operating, it sucks in odors within the toilet bowl 1 through the exhaust port 43 and forcibly sends them to the deodorizing filter 44, where the odor is removed, and odor-reduced air is discharged from the exhaust port 43.

[0017] Next, the electrical configuration of the cleaning toilet seat device 10 will be described with reference to Figure 4. Reference numeral 51 denotes a control unit that electrically controls each part of the cleaning toilet seat device 10, and is composed of a microcomputer, storage means 52 such as a readable and writable memory that stores various information and data, timing means 53 that measures time, and drive elements for each part. The input port of the control unit 51 is electrically connected to the main body operation unit 21, the seating switch 19, toilet seat temperature detection means 54, and water temperature detection means 55. The output port of the control unit 51 is electrically connected to the water stop mechanism 33, the pump 34, the toilet seat heater 56, the tank 57, and the nozzle motor 58.

[0018] The toilet seat heater 56 heats the toilet seat 12 to increase the surface temperature of the toilet seat 12, and in this embodiment an electric wire heater is used as the toilet seat heater 56, but this is just one example, and other heating means may be used, such as a lamp heater configured by passing a filament through the inside of a glass tube and sealing halogen gas in it. The toilet seat temperature detection means 54 detects the surface temperature of the toilet seat 12, and in this embodiment a thermistor is used, but this is just one example, and other temperature detection means may be used, such as an infrared sensor.

[0019] The tank 57 stores water flowing in from the water stop mechanism 33, heats the stored water with a built-in heater to raise the water temperature, and supplies the heated water to the flushing nozzle 25. The tank 57 functions as a heating unit that heats the water flowing in the toilet seat washing device 10. The tank 57 in this embodiment also has a valve that starts and stops the flow of stored water to the flushing nozzle 25, functioning as a water stop means for starting and stopping the flow of water to the flushing nozzle 25. In this embodiment, the valve is configured as an electric valve and controlled by an electrical signal from the control unit 51, but this is just one example. The water temperature detection means 55 detects the temperature of the water stored in the tank 57 and is provided in the tank 57 using, for example, a thermistor. Instead of the tank 57, an instantaneous heating unit that heats the passing water to instantly raise the water temperature may be used as the heating unit. The water temperature detection means 55 may also be provided, for example, near the water flow path between the tank 57 and the flushing nozzle 25.

[0020] The nozzle motor 58, when driven, linearly reciprocates the cleaning nozzle 25 along the axial direction, thereby causing the entire cleaning nozzle 25 to reciprocate along the front-rear direction of the main body 11.

[0021] The control unit 51 has the function of receiving a signal from the seat switch 19, detected temperature signals from the toilet seat temperature detection means 54 and the water temperature detection means 55, and an operation signal from the main body operation unit 21, and outputting control signals to the water stop mechanism 33, the toilet seat heater 56, the tank 57, and the nozzle motor 64 at predetermined timing based on the timing of the timing means 53. These functions are realized by the control unit 51 reading the programs and settings stored in the storage means 53, which serves as a storage medium.

[0022] 5 shows a plan view of the main body operation unit 21. A plurality of buttons 61-1 to 61-13 are arranged on the top surface of the main body operation unit 21, and these plurality of buttons 61-1 to 61-13 are operation means for performing operations related to the spraying of cleansing water. Of these plurality of buttons 61-1 to 61-13, buttons 61-2 and 61-3 are operation means for starting cleaning. On the front side of the top surface of the main body operation unit 21, on the left side in Figure 5, there are arranged, in order from front to rear, a stop button 61-1, a butt button 61-2, a bidet button 61-3, and a move button 61-4.Furthermore, there are arranged, in order, a front button 61-5 and a rear button 61-6 for adjusting the nozzle position on the right side of the center, a weak button 61-7 and a strong button 61-8 for adjusting the water pressure on the left side of the center, a hot water temperature adjustment button 61-9 located behind the strong button 61-8, a toilet seat temperature adjustment button 61-10 located behind the rear button 61-6, a cleaning / washing button 61-11 located behind the hot water temperature adjustment button 61-9, an outing button 61-12 located behind the toilet seat temperature adjustment button 61-10, and a power saving button 61-13 located behind the cleaning / washing button 61-11.

[0023] Additionally, a water pressure adjustment display unit 62 is provided on the top surface of the main body operation unit 21, between the weak button 61-7 and the strong button 61-8. By pressing the weak button 61-7 or the strong button 61-8, the water pressure sprayed from the nozzle of the washing nozzle 25, i.e., the water pressure released from the pump 34, can be adjusted in four stages, and the water pressure adjustment display unit 62 displays the water pressure at that time in four stages from high to low. The water pressure adjustment display unit 62 has multiple (four) light-emitting units 62-1 to 62-4 that are aligned from left to right and become narrower as they go, with the wider light-emitting units indicating that the water pressure is adjusted higher than the narrower light-emitting units. By pressing the weak button 61-7 or the strong button 61-8, the illuminated light-emitting sections 62-1 to 62-4 of the water pressure adjustment display section 62 move up or down and change; each time the weak button 61-7 is pressed, the narrower lower light-emitting sections light up, for example, light-emitting section 62-1 → light-emitting section 62-2 → light-emitting section 62-3, and each time the strong button 61-8 is pressed, the wider upper light-emitting sections light up, for example, light-emitting section 62-4 → light-emitting section 62-3 → light-emitting section 62-2.

[0024] Reference numeral 63 denotes a hot water temperature adjustment display, which is provided between the strong button 61-8 and the hot water temperature adjustment button 61-9. By pressing the hot water temperature adjustment button 61-9, the temperature of the water sprayed from the nozzle of the washing nozzle 25, i.e., the output of the tank 57, can be adjusted in three stages, and the hot water temperature adjustment display 63 displays the water temperature at that time in three stages from high to low. The hot water temperature adjustment display 63 has multiple (three) light-emitting elements that are aligned from left to right and become narrower, and the wider light-emitting elements indicate that the water temperature is adjusted higher than the narrower light-emitting elements.

[0025] Reference numeral 64 denotes a toilet seat temperature adjustment display, which is located between the rear button 61-6 and the toilet seat temperature adjustment button 61-10. By pressing the toilet seat temperature adjustment button 61-10, the surface temperature of the toilet seat 12, i.e., the output of the toilet seat heater 56, can be adjusted to three levels, and the toilet seat temperature adjustment display 64 displays the water temperature at that time in three levels from high to low. The toilet seat temperature adjustment display 64 has multiple (three) light-emitting elements that are aligned from left to right and become narrower, with the wider light-emitting elements indicating that the surface temperature of the toilet seat 12 is adjusted higher than the narrower light-emitting elements.

[0026] In addition, an outing mode display unit 65 serving as a notification means is provided near the outing button 61-12. The outing mode display unit 65 is made up of an LED or the like, and emits light when the cleaning toilet seat device 10 is in the outing mode, which will be described later.

[0027] Further, adjacent to the power saving button 61-13, there are provided notification means, a standby power saving mode display section 66 and a power stop power saving mode display section 67. These standby power saving mode display section 66 and power stop power saving mode display section 67 are made of LEDs or the like, and the standby power saving mode display section 66 lights up when the washing toilet seat device 10 is in the standby power saving mode (to be described later), and the power stop power saving mode display section 67 lights up when the washing toilet seat device 10 is in the power stop power saving mode (to be described later).

[0028] As described above, in this embodiment, light emitting units 62 to 67 are provided as the main body display unit 22. The light emitting units 62 to 67 may be configured to turn off after a predetermined time has elapsed since they were turned on, thereby saving power. The arrangement of the main body operating unit 21 and the main body display unit 22 shown in Figure 5 is merely an example, and can be changed, added, or deleted as appropriate depending on the specifications of the toilet seat cleaning device 10.

[0029] When the cleaning / washing button 61-11 is pressed, the washing nozzle 25 appears and disappears, and the washing nozzle 25 is washed with the washing liquid.

[0030] Next, the operation of the above-configured toilet seat cleaning device 10, particularly when the power-saving mode is executed, will be described in detail with reference to Figures 7 and 8. For the sake of convenience, only the explanation regarding the execution of the power-saving mode will be mentioned from here on.

[0031] The cleansing toilet seat device 10 of this embodiment has two power-saving modes: a power-saving mode in which the amount of heating by the toilet seat heater 56 is repeatedly reduced at predetermined time periods to make the temperature of the toilet seat 12 lower than the temperature corresponding to the display on the toilet seat temperature adjustment display unit 64, which is the surface temperature of the toilet seat 12 set during normal use, and the amount of heating by the heater in the tank 57 is reduced to make the temperature of the water sprayed from the nozzle of the cleansing nozzle 25 lower than the temperature corresponding to the display on the hot water temperature adjustment display unit 63, which is the water temperature set during normal use; and an out-of-home mode in which the power to the toilet seat heater 56 is cut off and stopped for a predetermined period of time, only once.

[0032] First, we will explain the normal state when the power saving mode is not being executed. When the power plug (not shown) is inserted into an outlet to energize the toilet seat washing device 10, the control unit 51 controls the main body display unit 22 to illuminate the light-emitting units 62-67 corresponding to the settings stored in the storage unit 52. The control unit 51 also controls the toilet seat heater 56 to be turned on or off based on the temperature detected by the toilet seat temperature detection unit 54 so that the temperature of the toilet seat 12 is raised to and maintained at the temperature corresponding to the display of the toilet seat temperature adjustment display unit 64, for example, 33°C to 36°C, in accordance with the executed program and settings, and adjusts the output of the tank 57 based on the temperature detected by the water temperature detection unit 55 so that the temperature of the water sprayed from the outlet of the washing nozzle 25 is the temperature corresponding to the display of the hot water temperature adjustment display unit 63, which is the setting stored in the storage unit 52, for example, 34°C to 40°C.

[0033] When the user sits on the toilet seat 12 and presses the butt button 61-2 or the bidet button 61-3, the control unit 51 receives an operation signal from the butt button 61-2 or the bidet button 61-3, and the control unit 51 controls the nozzle motor 58 to move the cleaning nozzle 25 forward from the main body 11 and stop it at a set position according to the program or settings. The control unit 51 then controls the water stop device 33 to open, causes water from the main body water inlet 31 to flow into the flow path between the water stop mechanism 33 and the cleaning nozzle 25, and controls the pump 34 so that the water flowing through the flow path is at a pressure according to the program or settings. The water flowing through the flow path is stored in the tank 57, and is heated by the heater in the tank 57, raising the water temperature to a temperature corresponding to the display on the hot water temperature adjustment display unit 63. The water whose temperature has risen to that temperature flows out of the tank 57 into the flow path and is sprayed from the outlet of the cleaning nozzle 25.

[0034] Next, the power-saving mode will be described. First, a method for setting the power-saving mode will be described. When the power-saving button 61-13 is pressed once to cancel the power-saving mode in which neither the standby power-saving mode indicator 66 nor the power-off power-saving mode indicator 67 is illuminated, the control unit 51 controls the main body display unit 22 to illuminate the standby power-saving mode indicator 66 and turn off the other light-emitting units 62 to 65 and 67, thereby transitioning to the standby power-saving mode. When the power-saving button 61-13 is pressed once in the standby power-saving mode, the control unit 51 controls the main body display unit 22 to illuminate the power-off power-saving mode indicator 67 and turn off the other light-emitting units 62 to 66, thereby transitioning to the power-off power-saving mode. When the power-saving button 61-13 is pressed once in the power-off power-saving mode, the control unit 51 controls the main body display unit 22 to illuminate the light-emitting units 62 to 67, similar to the normal mode, thereby canceling the power-saving mode and transitioning to the normal mode.

[0035] In the standby power saving mode, the control unit 51 starts the transition based on the time measured by the clock means 53, and the power saving time period T is determined in advance, for example, 8 hours. OFF The amount of heating by the toilet seat heater 56 is reduced, and the toilet seat heater 56 is controlled to be turned on and off based on the temperature detected by the toilet seat temperature detection means 54 so that the temperature of the toilet seat 12 becomes a temperature lower than the temperature corresponding to the display on the toilet seat temperature adjustment display unit 64, for example, 28°C, and the amount of heating by the heater in the tank 57 is reduced, and the output of the heater in the tank 57 is adjusted based on the temperature detected by the water temperature detection means 55 so that the temperature of the water sprayed from the outlet of the washing nozzle 25 becomes a temperature lower than the temperature corresponding to the display on the hot water temperature adjustment display unit 63, for example, 25°C.

[0036] When the user sits on the toilet seat 12, the seat switch 19 is pressed, and the control unit 51 receives an operation signal from the seat switch 19. The control unit 51 controls the toilet seat heater 56 to be turned on or off based on the temperature detected by the toilet seat temperature detection means 54 so that the temperature of the toilet seat 12 rises to and is maintained at the temperature corresponding to the display on the toilet seat temperature adjustment display 64, and adjusts the output of the heater in the tank 57 based on the temperature detected by the water temperature detection means 55 so that the temperature of the water sprayed from the outlet of the cleaning nozzle 25 reaches the temperature corresponding to the display on the hot water temperature adjustment display 63. The control unit 51 also controls the main body display unit 22 to illuminate the light-emitting units 62 to 65, 67 as in the normal state. When the butt button 61-2 or the bidet button 61-3 is pressed, the control unit 51 controls the water stop device 33 to move the cleaning nozzle 25 forward from the main body 11 and open it, as described above, and controls the pump 34 so that the water flowing through the flow path reaches the set pressure. Furthermore, the water stored in the tank 57 is heated by the heater of the tank 57 to increase the water temperature, and the water flows out of the tank 57 into the flow path and is discharged from the nozzle of the washing nozzle 25 .

[0037] Thereafter, when the user stands up and removes their buttocks from the toilet seat 12, the seat switch 19 that had been pressed is turned OFF, and the control unit 51 again reduces the amount of heating by the toilet seat heater 56, controls the toilet seat heater 56 to be turned on or off based on the temperature detected by the toilet seat temperature detection means 54 so that the temperature of the toilet seat 12 becomes the aforementioned low temperature, reduces the amount of heating by the heater in the tank 57, adjusts the output of the heater in the tank 57 based on the temperature detected by the water temperature detection means 55 so that the temperature of the water sprayed from the outlet of the washing nozzle 25 becomes the aforementioned low temperature, and controls the main body display unit 22 to illuminate the standby power saving mode display unit 66 and turn off the other light-emitting units 62 to 65, 67. By configuring in this way, the washing toilet seat device 10 can save power while quickly returning to the normal state when in use.

[0038] After that, during the predetermined power saving time period T OFF When the control unit 51 receives a timing signal from the timing means 53 indicating that the power saving time period T OFFAfter the time has elapsed, for example, 24 hours - 8 hours = 16 hours, a predetermined normal time period T ON Then, as in the normal state described above, the toilet seat heater 56 is controlled to be turned on or off based on the temperature detected by the toilet seat temperature detection means 54 so that the temperature of the toilet seat 12 rises to and is maintained at the temperature corresponding to the display on the toilet seat temperature adjustment display 64, and the output of the heater of the tank 57 is adjusted based on the temperature detected by the water temperature detection means 55 so that the temperature of the water sprayed from the nozzle of the washing nozzle 25 reaches the temperature corresponding to the display on the hot water temperature adjustment display 63. The control unit 51 also controls the main body display unit 22 to light the light-emitting units 62 to 65, 67 as in the normal state. Then, during the predetermined normal state time period T ON When the control unit 51 receives a time signal from the time measuring means 53 indicating that the time period T ON After the predetermined power saving time period T OFF Then, the amount of heating by the toilet seat heater 56 is reduced again, and the toilet seat heater 56 is controlled to be turned on or off based on the temperature detected by the toilet seat temperature detection means 54 so that the temperature of the toilet seat 12 becomes the aforementioned low temperature, and the amount of heating by the heater in the tank 57 is reduced, and the output of the heater in the tank 57 is adjusted based on the temperature detected by the water temperature detection means 55 so that the temperature of the water sprayed from the outlet of the cleaning nozzle 25 becomes the aforementioned low temperature, and the main body display unit 22 is controlled to illuminate the standby power saving mode display unit 66 and turn off the other light-emitting units 62 to 65, 67.

[0039] In the power-off power-saving mode, the control unit 51 determines whether the power-off power-saving mode is in a predetermined power-saving time period T, such as 8 hours, based on the time measured by the clocking means 53. OFF At this time, the toilet seat heater 56 is de-energized and stopped, and the tank 57 is de-energized and stopped.

[0040] When the user sits on the toilet seat 12, the seat switch 19 is pressed in the same manner as described above, and the control unit 51 controls the toilet seat heater 56 to be turned on or off based on the temperature detected by the toilet seat temperature detection means 54 so that the temperature of the toilet seat 12 rises to and is maintained at the temperature corresponding to the display on the toilet seat temperature adjustment display unit 64, and also adjusts the output of the heater in the tank 57 based on the temperature detected by the water temperature detection means 55 so that the temperature of the water sprayed from the outlet of the cleaning nozzle 25 reaches the temperature corresponding to the display on the hot water temperature adjustment display unit 63. The control unit 51 also controls the main body display unit 22 to illuminate the light-emitting units 62 to 65, 67 as in the normal state. Thereafter, when the user stands up and removes their buttocks from the toilet seat 12, the seat switch 19 that was pressed is turned off, and the control unit 51 again cuts off the power to the toilet seat heater 56 and cuts off the power to the heater in the tank 57.

[0041] After that, during the predetermined power saving time period T OFF When the control unit 51 receives a timing signal from the timing means 53 indicating that the power saving time period T OFF After the predetermined normal state time period T ON Then, the same control as in the normal state described above is performed.

[0042] Next, referring to Figure 8, the power saving time period T OFF When the butt button 61-2 and the bidet button 61-3 are pressed and held down simultaneously for several seconds, the control unit 51 displays, for example, the power saving time period T OFF If the setting is 8 hours, only the light emitting part 62-1 is illuminated as shown in (B), and the current power saving time period T OFF Then, each time the butt button 61-2 is pressed, the main body display unit 22 is controlled in the following order, for example: (C) only the light-emitting unit 62-2 is illuminated → (D) only the light-emitting unit 62-3 is illuminated → (E) only the light-emitting unit 62-4 is illuminated → (A) both the light-emitting unit 62-1 and the light-emitting unit 62-4 are illuminated → (B) only the light-emitting unit 62-2 is illuminated, and the time period T OFFThe setting is changed, for example, from (C) 7 hours to (D) 6 hours to (E) 5 hours to (A) 9 hours to (B) 8 hours, and the changed setting is stored in the storage means 52. After that, if there is no operation on the main body operation unit 21 for a predetermined period, the control unit 51 controls the main body display unit 22 to return to the display before the simultaneous pressing of the rear button 61-2 and the bidet button 61-3. In this embodiment, in the power saving time period T OFF +Normal state time period T ON is set to 24 hours, so the normal time period T ON The power saving time is 15 hours for the setting (A), 16 hours for the setting (B), 17 hours for the setting (C), 18 hours for the setting (D), and 19 hours for the setting (E), but these are just examples, and the present invention is not limited to these values ​​and operations. OFF The power saving time period T may be set to 24 hours, so that the standby power saving mode or the power-off power saving mode can be continuously performed all day, thereby further saving power. OFF However, the standby power saving mode and the power-off power saving mode have different power saving time periods T OFF In this case, the configuration may be such that each can be set individually.

[0043] Next, the outing mode will be described. First, a method for setting the outing mode will be described. When the outing button 61-12 is pressed once while the outing mode is released and the outing mode display unit 65 is not illuminating, the control unit 51 controls the main body display unit 22 to illuminate the outing mode display unit 65 and turn off the other light-emitting units 62 to 64, 66, and 67, thereby transitioning to the outing mode. When the outing button 61-12 is pressed once while the outing mode is released, the control unit 51 controls the main body display unit 22 to illuminate the light-emitting units 62 to 67 in the same manner as before the transition to the outing mode, thereby canceling the outing mode and transitioning to the state before the transition to the outing mode.

[0044] In the outing mode, the control unit 51 counts the outing time period T, which is set, for example, two hours from the start of the transition, based on the time counted by the timing means 53. GO Then, the toilet seat heater 56 is de-energized and stopped, and the heater of the tank 57 is de-energized and stopped.

[0045] When the user sits on the toilet seat 12, the seat switch 19 is pressed as described above, and the control unit 51 cancels the outing mode, and if the power saving mode is set in addition to the outing mode, for example, the control unit 51 switches to the power saving mode, or if the power saving mode is canceled, the control unit 51 switches to the normal state.

[0046] The control unit 51 starts the outing mode without receiving an operation signal from the seat switch 19, and the outing time period T GO When the control unit 51 receives a timing signal from the timing means 53 indicating that the time period T has elapsed, the control unit 51 ends the outing mode, and for example, if the power saving mode is set, the control unit 51 shifts to the power saving mode, or if the power saving mode is released, the control unit 51 shifts to the normal state. Therefore, the outing mode is set only once, and the outing time period T GO During this time, the toilet seat heater 56 is turned off and the heater of the tank 57 is turned off and the toilet seat heater 56 is turned off, thereby functioning as a power saving mode. GO During this time, the amount of heating by the toilet seat heater 56 is reduced below the amount of heating at the temperature corresponding to the display on the toilet seat temperature adjustment display unit 64, and the toilet seat heater 56 is controlled to be turned on or off based on the temperature detected by the toilet seat temperature detection means 54 so that the temperature of the toilet seat 12 becomes the aforementioned low temperature, and the amount of heating by the heater of the tank 57 is reduced below the amount of heating at the temperature corresponding to the display on the hot water temperature adjustment display unit 63, and the output of the heater of the tank 57 is adjusted based on the temperature detected by the water temperature detection means 55 so that the temperature of the water sprayed from the outlet of the cleaning nozzle 25 becomes the aforementioned low temperature.

[0047] Next outing time T GOWhen the outing button 61-12 is pressed and held for several seconds, the control unit 51 displays the current outing time period T on the hot water temperature adjustment display unit 63 and the toilet seat temperature adjustment display unit 64. GO The main body display unit 22 is controlled to emit light in the light emitting unit corresponding to the setting of the outing time period T GO If the setting is 2 hours, the lowermost light emitting part of the toilet seat temperature adjustment display part 64 is illuminated, and as the time setting increases from 4 hours to 6 hours, the main body display part 22 is controlled so that the illuminated light emitting part moves upward, and if the setting is 12 hours, the uppermost light emitting part of the hot water temperature adjustment display part 63 is illuminated. OFF Similarly to the case of (1), each time the buttocks button 61-2 is pressed, the main body display unit 22 is controlled to move the illuminating light-emitting part upward, and after the topmost light-emitting part of the hot water temperature adjustment display unit 63, the light-emitting part is controlled to move to the bottommost light-emitting part of the toilet seat temperature adjustment display unit 64, and the outing time period T GO The setting of the outing time period T GO The setting can be set between 2 hours and 12 hours, for example, and the power saving time period T OFF The range is wider than the setting of (1), allowing power saving for a desired length of time when unplanned power saving is desired. After that, if the main body operation unit 21 is not operated for a predetermined period, the control unit 51 controls the main body display unit 22 to return to the display before the outing button 61-12 was pressed and held for several seconds. Note that the above-mentioned setting times are merely examples, and the present invention is not limited to these.
