In these cases, the detection unit of the temperature detection unit and / or the detection unit of the humidity detection unit are separated from the toilet seat functioning as a heating toilet seat and the heating unit for generating hot water, which is advantageous for ensuring the detection accuracy of the detection unit. . When a hot water tank is mounted, it is preferable to separate it from the hot water tank. The distance away from these components can be selected as appropriate, but is preferably 3 cm or more and 5 cm or more, and can be 10 cm or more and 50 cm or more. Alternatively, a heat insulating structure (for example, a heat insulating space or a heat insulating material) can be appropriately provided between the detection unit of the temperature detection unit and / or the detection unit of the humidity detection unit and the toilet seat or / and the heating unit for generating hot water.

  A first embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the toilet seat device according to this embodiment is a human body local cleaning device 1. The human body local cleaning device 1 is mounted on the rear part of a Western-style toilet 2, and includes a case 4 as a base having an operation panel 3 on the upper surface, a toilet seat 5 provided on the case 4 so as to be rotatable, 4 is provided with a toilet lid 6 rotatably provided. The cleaning unit includes a female local cleaning nozzle 7 and a defecation local cleaning nozzle 8. The case 4 is provided with a control board and the like, and is integrated with the first case 4a and the first case 4a located behind the toilet seat 5 (the direction opposite to the direction in which the user seated on the toilet seat 5 faces). Second case 4c. The second case 4 c is arranged on the side of the user who sits on the toilet seat 5.

  The female local washing nozzle 7 is concealed so as not to be seen by the user when not in use. When the female local washing switch 9 is operated, the female local washing nozzle 7 moves forward toward the female local area of the user sitting on the toilet seat 5. When the use is finished, it is retracted again and concealed. The defecation local part washing nozzle 8 is concealed so as not to be seen by the user when not in use, and when the defecation local part washing switch 10 is operated, it moves forward toward the defecation local part of the user sitting on the toilet seat 5. When the use is finished, it is retracted again and concealed.

  FIG. 2 shows a block diagram. As shown in FIG. 2, a hot water generating heater 11 that generates hot water to be supplied to a female local cleaning switch 9, a defecation local cleaning switch 10, and a female local cleaning nozzle 7 and a defecation local cleaning nozzle 8 that constitute the cleaning unit. (Heating unit for warm water generation), toilet seat heater 12 (toilet seat heating unit) for heating the toilet seat 5, temperature sensor 13 (temperature detection means) for detecting the temperature Ta of the toilet space R, and humidity Wa of the toilet space R Humidity sensor 14 (humidity detection means) to detect, automatic mode setting switch 15 (automatic mode setting unit) for switching to an automatic mode for automatically setting the set temperature A of hot water and the set temperature B of the toilet seat 5, and setting of hot water Manual setting switch 16 for hot water (manual setting unit) for manually setting temperature A and manual setting switch 17 for manual heating heating seat (set manually) for setting temperature B of toilet seat 5 Setting portion) are provided.

  In addition, when the automatic mode setting switch 15 is set to the automatic mode, the hot water preference temperature setting switch 20 (hot water preference temperature setting unit) set by the user to increase or decrease the favorite temperature of the hot water, and the toilet seat 5 A toilet seat preference temperature setting switch 22 (toilet seat preference temperature setting unit) set by the user to increase the favorite temperature is provided on the operation panel 3 provided on the upper surface of the second case portion 4c. These signals are input to the control unit 24. The control unit 24 includes an input processing circuit 25, a microcomputer 26, an output processing circuit 27 that outputs a control signal based on a signal from the microcomputer 26, and a memory 28 (storage medium) such as a RAM and a ROM. The microcomputer 26 has a timer function.

  The heater 11 for generating hot water may be a hot water tank type in which water stored in a tank mounted on the case 4 is connected by a heater so as to be connected to the water supply passage, or may be mounted on the case 4 without having a hot water tank. An instantaneous hot water supply type in which the water in the water supply passage is heated with a heater may be used. The toilet seat heater 12 is formed of a heating element mounted on the toilet seat 5. The temperature sensor 13 and the humidity sensor 14 may be mounted on the case 4, or may be provided on the room wall of the toilet space R away from the case 4 or on another part of the toilet space R.

  Note that the temperature sensor 13 and the humidity sensor 14 may be housed in the remote control device as long as the human body local cleaning device 1 is operated by a remote control device (not shown). In this case, the remote control device is detachably suspended on the wall of the toilet space R, which is thermally shielded away from the toilet seat 5 and the warm water generating heater 11, so that the influence of the hot water or the heated toilet seat is avoided. Thus, temperature and / or humidity detection accuracy is ensured. The remote control device is used by a user to operate various switches such as a cleaning switch.

  When the automatic mode setting switch 15 is set to the automatic mode, the control unit 24 automatically controls both the set temperature A of the hot water and the set temperature B of the toilet seat 5 according to the temperature Ta of the toilet space R. Specifically, when the temperature Ta of the toilet space R is relatively low, the control unit 24 automatically sets the set temperature A of hot water when the temperature of the toilet space R is relatively higher than a predetermined temperature. The control to raise is executed. In addition, when the temperature Ta of the toilet space R is relatively high, the control unit 24 automatically controls the set temperature A of the hot water to be lower than when the temperature of the toilet space R is relatively lower than the predetermined temperature. Execute.

  As described above, the control unit 24 automatically sets the set temperature A of the hot water for cleaning the local part of the human body according to the change in the temperature Ta of the toilet space R. For this reason, regardless of the change in the temperature Ta of the toilet space R, the hot water discharged from the female local washing nozzle 7 toward the female local area of the human body or the defecation local cleaning nozzle 8 is discharged toward the defecation local area of the human body. Hot water will be at the proper temperature. That is, the hot water discharged from the female local cleaning nozzle 7 and the defecation local cleaning nozzle 8 toward the local area of the human body becomes an appropriate temperature regardless of the season, or in the early morning, night, and daytime.

  Furthermore, according to the present embodiment, when the temperature Ta of the toilet space R is relatively low, the control unit 24 increases the set temperature B of the toilet seat 5 than when the temperature Ta of the toilet space R is relatively high. Execute control. Further, when the temperature Ta of the toilet space R is relatively high, the control unit 24 performs control to lower the set temperature B of the toilet seat 5 than when the temperature of the toilet space R is relatively lower than the predetermined temperature. Execute. In this way, the set temperature B of the toilet seat 5 is automatically set according to the change in the temperature Ta of the toilet space R. For this reason, the temperature of the toilet seat 5 becomes an appropriate temperature regardless of the change in the temperature Ta of the toilet space R. That is, the temperature of the toilet seat 5 becomes an appropriate temperature regardless of the season, or regardless of early morning, night, or daytime.

  3 and 4 show an example of a flowchart executed by the control unit 24 (the flowchart is not limited to this). First, the state of the automatic mode setting switch 15 is read (step S2). Then, it is determined whether or not the automatic mode setting switch 15 is set to the automatic mode (step S3). If YES, the automatic mode for automatically setting the set temperature A of the hot water and the set temperature B of the toilet seat 5 is executed (step S4). If NO, the manual control mode is executed (step S6).

FIG. 4 shows a flowchart of the automatic mode. As shown in FIG. 4, the control unit 24 reads a signal of the temperature Ta of the toilet space R detected by the temperature sensor 13 (step S402). In this case, a plurality of signals are read, and the average value is set as the temperature Ta of the toilet space R. Next, the control unit 24 compares the detected temperature Ta with the first threshold temperature T1 on the low temperature side (step S404). If the detected temperature Ta is lower than the first threshold temperature T1, it corresponds to the winter season, so the control unit 24 sets the set temperature A of hot water to A _high (high temperature: 40 ° C., for example), and the toilet seat 5 The set temperature B is set to B _high (high temperature: for example, 40 ° C.) (step S406). Therefore, step S406 functions as a temperature raising means for automatically raising the set temperature of the hot water and the set temperature of the toilet seat 5 when the temperature Ta temperature of the toilet space R is relatively lower than the predetermined temperature.

If the detected temperature Ta is equal to or higher than the first threshold temperature T1, the control unit 24 compares the detected temperature Ta with the second threshold temperature T2 on the high temperature side (step S408). If the detected temperature Ta is lower than the second threshold temperature T2, it corresponds to the spring or autumn season, so the control unit 24 sets the set temperature A of hot water to A _middle (medium temperature: 38 ° C., for example). Further, the set temperature B of the toilet seat 5 is set to B _middle (medium temperature: for example, 36 ° C.) (step S410).

If the detected temperature Ta is equal to or higher than the second threshold temperature T2, it corresponds to summer, so the control unit 24 sets the set temperature A of hot water to A _low (low temperature: 36 ° C., for example). Furthermore, the set temperature B of the toilet seat 5 is set to B _low (low temperature: for example, 26 ° C.) (step S412). Therefore, step S412 functions as a temperature lowering means that automatically increases the set temperature of the hot water and the set temperature of the toilet seat 5 when the temperature Ta temperature of the toilet space R is relatively higher than a predetermined temperature. If the detected temperature Ta is equal to or higher than the second threshold temperature T2, the control unit 24 may turn off the set temperature B of the toilet seat 5 and set it in a disconnected state. Note that A _high > A _middle > A _low . There is also a relationship between the _{B high> B middle> B low} . In the present embodiment, the humidity sensor 14 is provided, but may be eliminated if not particularly necessary.

  According to the present embodiment in which the above control is executed, the set temperature A of the hot water discharged from the female local washing nozzle 7 and the defecation local washing nozzle 8 is automatically set according to the change in the temperature Ta of the toilet space R. Further, the temperature adjustment characteristics as shown in FIG. Therefore, according to the present embodiment, the set temperature A of the hot water discharged from the female local washing nozzle 7 and the defecation local washing nozzle 8 is in the range of 36 to 40 ° C. according to the seasonal change such as summer, autumn, winter, and spring. It can be adjusted automatically within the interior, which is advantageous for enhancing the comfort of toilet use. Therefore, even if the season changes, the user does not have to manually adjust the set temperature A of the hot water according to the change of the season.

  Further, the temperature of the toilet seat 5 is automatically set to a temperature adjustment characteristic as shown in FIG. 6 according to a change in the temperature Ta of the toilet space R. Therefore, according to the present embodiment, the set temperature B of the toilet seat 5 can be automatically adjusted within the range of 26 to 40 ° C. according to the change of seasons such as summer, autumn, winter, and spring. It is advantageous to increase comfort. Therefore, even if the season changes, the user does not have to adjust the set temperature B of the toilet seat 5 in accordance with the change of the season. In addition, the numerical value of the temperature of the vertical axis | shaft shown in FIG. 5 and FIG. 6 is an illustration, and is not limited to this numerical value.

  The set temperature A of the hot water and the set temperature B of the toilet seat 5 may be set even when the toilet is not used and is on standby. Alternatively, it may be set when the user enters the toilet room or sits on the toilet seat 5.

  The second embodiment has basically the same operations and effects as the first embodiment. According to the present embodiment, the humidity sensor 14 (humidity detection means) that directly or indirectly detects the humidity of the toilet space R is provided on the wall of the case 4 or the toilet space R together with the temperature sensor 13. The control unit 24 raises or lowers the set temperature A of the hot water according to the humidity detected by the humidity sensor 14. That is, when the temperature Ta of the toilet space R is higher than the first predetermined temperature, that is, T2, and the humidity Wa of the toilet space R is higher than the first predetermined humidity Wa1 (high humidity: for example, 60% humidity) One feels muggy. For this reason, the control unit 24 sets the set temperature A of the hot water to ΔT1 (for example, an arbitrary value of 1 to 2 ° C.) than when the humidity Wa of the toilet space R is lower than the first predetermined humidity Wa1 (for example, humidity 60%). Reduce. Further, the control unit 24 lowers the set temperature B of the toilet seat 5 by ΔT2 (for example, an arbitrary value of 1 to 2 ° C.), or turns off the toilet seat heater 12 to bring it into a disconnected state. Thereby, set temperature A of warm water and set temperature B of toilet seat 5 heating can be made to cope with a hot and humid time.

FIG. 7 shows a flowchart of the automatic mode. As shown in FIG. 7, first, a signal of the temperature Ta of the toilet space R detected by the temperature sensor 13 and a signal of the humidity Wa of the toilet space R detected by the humidity sensor 14 are read (step SH402). If the detected temperature Ta is lower than the first threshold temperature T1, it corresponds to the winter season, so the set temperature A of the hot water is set to A _high (high temperature: 40 ° C., for example), and the set temperature B of the toilet seat 5 is set to B _High (high temperature: for example, 40 ° C.) is set (step SH406). Therefore, step SH406 functions as a temperature raising means for automatically raising the set temperature of the hot water and the set temperature of the toilet seat 5 when the temperature Ta temperature of the toilet space R is relatively lower than the predetermined temperature.

If the detected temperature Ta is equal to or higher than the first threshold temperature T1, the detected temperature Ta is compared with the second threshold temperature T2 (step SH408). If the detected temperature Ta is lower than the second threshold temperature T2, it corresponds to spring or autumn, so the set temperature A of hot water is set to A _middle (medium temperature: 38 ° C., for example) and the toilet seat 5 is set. The temperature B is set to B _middle (medium temperature: for example, 36 ° C.) (step SH410).

If the detected temperature Ta is equal to or higher than the second threshold temperature T2 (corresponding to the first predetermined temperature), the temperature Ta of the toilet space R is relatively high and is determined to be summer, so The humidity Wa is compared with the first predetermined humidity Wa1 (for example, humidity 60%) (step SH409). If the humidity Wa of the toilet space R is lower than the first predetermined humidity Wa1 (for example, humidity 60%), the user does not feel so humid. Therefore, the set temperature A of the hot water is set to A _low (low temperature: eg 36 ° C.), and the set temperature B of the toilet seat 5 is set to B _low (low temperature: eg 26 ° C.) (step SH412). Therefore, step SH412 functions as a temperature lowering means for lowering the set temperature of the hot water and the set temperature of the toilet seat 5 when the temperature Ta temperature of the toilet space R is relatively lower than the predetermined temperature.

On the other hand, when the detected temperature Ta is equal to or higher than the second threshold temperature T2 and the humidity Wa of the toilet space R is higher than the first predetermined humidity Wa1 (for example, 60% humidity), the user feels muggy. Determined. For this reason, the control unit 24 lowers the set temperature A of the hot water by ΔT1 (for example, an arbitrary value of 1 to 2 ° C.) lower than A _low and sets the set temperature B of the toilet seat 5 by ΔT2 (for example, 1-2) from B _low. (Arbitrary value of ° C.) (step SH414). Therefore, step SH414 functions as a high-humidity temperature lowering means for lowering the set temperature A of hot water and / or the set temperature B of the toilet seat 5 when it is determined that the user feels that the humidity is high and humid.

  Here, ΔT1 = ΔT2, ΔT1≈ΔT2, ΔT1> ΔT2, and ΔT1 <ΔT2. The first predetermined humidity Wa1 is, for example, 60% humidity, but is not limited thereto, and the humidity may be 80%, 90%, or 95%.

  In the present embodiment, similarly to the first embodiment, the hot water discharged from the female local cleaning nozzle 7 and the defecation local cleaning nozzle 8 toward the human body is irrespective of the change in the temperature Ta of the toilet space R. It becomes the appropriate temperature. That is, the temperature of the toilet seat 5 becomes an appropriate temperature regardless of the season, or regardless of early morning, night, or daytime.

  Furthermore, even when the user feels hot and humid, the set temperature A for heating the toilet seat 5 is reduced by ΔT1, and the set temperature B for the toilet seat 5 is reduced by ΔT2, so that it is possible to cope with the hot and humid conditions.

  The third embodiment has basically the same operations and effects as the first and second embodiments. In the present embodiment, when the control mode is set to the automatic mode, a hot water preference temperature setting switch 20 (a warm water preference temperature setting unit) that sets a preferred temperature of hot water and a toilet seat that sets a preferred temperature of the toilet seat 5 are set. Based on the preference temperature setting switch 22 (toilet seat preference temperature setting unit), the preference temperature setting mode is executed.

  FIG. 8 shows a flowchart of the preferred temperature setting mode. As shown in FIG. 8, the state of the hot water favorite temperature setting switch 20 for setting the favorite temperature of hot water and the state of the toilet seat favorite temperature setting switch 22 for setting the favorite temperature of the toilet seat 5 are read (step S602). The operating state of the hot water preference temperature setting switch 20 is determined (step S604). If the hot water preference temperature setting switch 20 is set to a higher value, α1 is added to the set temperature A and the set temperature A is updated (step S608). ). Therefore, step S608 functions as an updating means for updating the set temperature A to a higher value when the hot water preference temperature setting switch 20 is set to a higher value.

  If the hot water preference temperature setting switch 20 is set to a low value, α2 is subtracted from the set temperature A to update the set temperature A (step S610). Therefore, step S610 functions as an updating means for updating the set temperature A to be lower when the hot water preference temperature setting switch 20 is set to be lower. Note that α1 = α2, α1≈α2, α1 <α2, and α1> α2.

  Next, the state of the toilet seat preference temperature setting switch 22 is determined (step S612). If the toilet seat preference temperature setting switch 22 is set higher, β1 is added to the set temperature B, and the set temperature B is updated (step S614). Therefore, step S614 functions as an updating means for updating the set temperature B of the toilet seat 5 to be higher when the toilet seat preference temperature setting switch 22 is set to be higher.

  If the toilet seat preference temperature setting switch 22 is set to a lower value, β2 is subtracted from the set temperature B to update the set temperature B (step S616). Therefore, step S616 functions as an updating means for updating the set temperature B of the toilet seat 5 to be lower when the toilet seat preference temperature setting switch 22 is set to be lower. Note that β1 = β2, β1≈β2, β1 <β2, and β1> β2.

  FIG. 9 shows a change in the set temperature A of the hot water, that is, a change in the temperature of the hot water. FIG. 10 shows changes in the set temperature B of the toilet seat 5. Depending on the user's preference, it can be set higher by α1 with respect to the set temperature A (standard set temperature) of hot water, or can be set lower by α2 with respect to the set temperature A. Further, according to the preference of the user, it can be set higher by β1 than the set temperature B of the toilet seat 5, or can be set lower by β2 than the set temperature B (standard set temperature) of the toilet seat 5. In addition, the numerical value of the temperature of the vertical axis | shaft shown in FIG. 9 and FIG. 10 is an illustration, and is not limited to this.

  The fourth embodiment has basically the same operations and effects as the first embodiment. The microcomputer 26 of the control unit 24 has a timer function, measures the elapsed time measured from the reference time by the timer function, determines the current season based on the elapsed time, and determines the current water heater 11 according to the season. The set temperature A of the (heating unit for warm water generation) and the set temperature B of the toilet seat 5 are controlled. A humidity sensor 14 (humidity detection means) that directly or indirectly detects the humidity of the toilet space R is provided. In the present embodiment, since the temperature sensor 13 for detecting the temperature of the toilet space R is not provided, the cost can be reduced.

FIG. 11 shows a flowchart of the automatic mode. As shown in FIG. 11, the elapsed time from the reference time is read (step SM402). In this case, the elapsed time can be read when a switch such as the defecation local washing switch 10 or the female local washing switch 9 (or a seating sensor if a seating sensor is provided) is turned on. It is determined from the elapsed time whether the current season is winter (step SM404). When it is determined that the current season is the winter season, the control unit 24 sets the set temperature A of the hot water to A _high (high temperature: 40 ° C., for example), and sets the set temperature B of the toilet seat 5 to B _high (high temperature: _high temperature: For example, it is set to 40 ° C. (step SM406). If the season is not winter, the control unit 24 determines from the elapsed time whether the current season is summer (step SM408). If the season is not summer, since the season corresponds to spring or autumn, the control unit 24 sets the set temperature A of the hot water to A _middle (medium temperature: 38 ° C., for example), and the set temperature B of the toilet seat 5 Is set to B _middle (medium temperature: 36 ° C., for example) (step SM410).

If the season is summer, the temperature Ta of the toilet space R is relatively high, and it is necessary to consider the heat of the heat. For this reason, the control unit 24 compares the humidity Wa of the toilet space R with the first predetermined humidity Wa1 (for example, humidity 60%) (step SM409). If the humidity Wa of the toilet space R is lower than the first predetermined humidity Wa1 (for example, humidity 60%), it is determined that the user does not feel too muggy. Therefore, the control unit 24 sets the set temperature A of the hot water to A _low (low temperature: eg 36 ° C.), and sets the set temperature B of the toilet seat 5 to B _low (low temperature: eg 28 ° C.) (step SM412). ).

On the other hand, when the humidity Wa of the toilet space R is higher than the first predetermined humidity Wa1 (for example, humidity 60%), it is determined that the user feels muggy. For this reason, the control unit 24 lowers the set temperature A of the toilet seat heating by ΔT1 (for example, an arbitrary value of 1 to 2 ° C.) from A _low and sets the set temperature B of the toilet seat 5 by ΔT2 (for example, 1 to 2) from B _low . (Arbitrary value of 2 ° C.) (Step SM414). Alternatively, the toilet seat heater 12 may be turned off so that the power is cut off. Here, ΔT1 = ΔT2, ΔT1≈ΔT2, ΔT1> ΔT2, and ΔT1 <ΔT2.

  Here, steps SM402, 404, and 408 can function as a season determination unit that determines the current season based on the elapsed time from the reference time measured by the timer function. Steps SM406, 410, and 412 control the set temperature A of the hot water and the set temperature B of the toilet seat according to the season determined by the season determination means, and increase the set temperature A and the set temperature B in the winter compared to the summer. In addition, it can function as a temperature adjusting means for lowering the set temperature A and the set temperature B in the summer than in the winter. Step SM414 functions as a temperature lowering means for lowering the set temperature A of the hot water and the set temperature B of the toilet seat 5 below the standard set temperature when it is determined that the user feels muggy.

  Also in the present embodiment, similarly to the first embodiment, the hot water discharged from the female local cleaning nozzle 7 and the defecation local cleaning nozzle 8 toward the local portion of the human body becomes an appropriate temperature regardless of the change in season. That is, the temperature of the toilet seat 5 becomes an appropriate temperature regardless of the season. Furthermore, even when the user feels muggy, such as during the rainy season, the set temperature A for heating the toilet seat 5 is reduced by ΔT1, and the set temperature B for the toilet seat 5 is reduced by ΔT2, so that the heat of heat is dealt with. Can do.

Are arranged as follows. The side surface 4s is disposed on the side opposite to the toilet seat 5 in the second case 4c. For this reason, even when the toilet seat 5 functions as a heating toilet seat, or even when the temperature of the hot water is high, the temperature sensor 13 and the humidity sensor 14 can be suppressed from being affected by the heating toilet seat and the hot water, Detection accuracy is ensured. In particular, since the detection portions 13a and 14a are arranged in the concave portion 4f formed on the side surface 4s, it is possible to prevent water, dust, and the like from adhering to the detection portions 13a and 14a.
