Description

TECHNICAL FIELD

[0001] The present application relates to a toilet system capable of providing a health index of a user. BACKGROUND

[0002] Patent Document 1 discloses a system that measures blood flow information of a user who sits on a toilet seat, and outputs (for example, displays on a display terminal) a health index calculated based on the measurement result.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2021-68396

[0004] The present inventors have found that, depending on the temperature state of a toilet seat, the blood flow state of a user who sits on the toilet seat is greatly affected.

[0005] For example, a laser sensor capable of measuring the blood flow state in the skin on the back side of the user's thigh is installed on the toilet seat, and a Fourier transform or the like is performed on the output signal of the laser sensor, whereby a plurality of health indexes such as pulse, blood flow, heart rate, and the like can be calculated.

[0006] Here, the present inventors have found that, for example, when a user sits on a cold toilet seat during a cold period in winter, the blood flow of the user who sits on the toilet seat deteriorates, and the health index calculated based on the blood flow state described above sometimes does not correctly reflect the actual health state. That is, if the calculation accuracy of the health index decreases due to the measurement of the blood flow state on a toilet seat with a reduced temperature, when health management is performed on a daily basis in a toilet, for example, even if there is no change in the health state of the user, fluctuations or the like occur in the output result of the health index, and the user can be unnecessarily confused or shaken. This can impair the reliability of the health index providing system.

[0007] In addition, in a case where the temperature of the toilet seat is greatly increased in a short time or the like, the temperature of the toilet seat greatly affects the blood flow of the user who sits on the toilet seat, and sometimes a large change (gradient) occurs in the blood flow state of the user. The blood flow state measured in the state described above can not correctly reflect the daily blood flow state of the user, and the health index calculated based on the blood flow state described above can not correctly reflect the actual health state. SUMMARY

[0008] The present application has been created based on the above insight. An object of the present application is to provide a toilet system capable of providing a health index of a user, in which a case in which a health index that does not correctly reflect an actual health state of the user is outputted as a health index that correctly reflects the actual health state is suppressed.

[0009] The present application is a toilet system characterized by comprising: a toilet seat having a seating surface on which a user sits; a sensor provided to the toilet seat and configured to measure a physical quantity that reflects blood flow information of the user; a health index calculation unit configured to calculate a health index of the user based on a measurement result of the sensor; a health index output unit configured to output the health index of the user calculated by the health index calculation unit; a temperature determination unit configured to determine whether a temperature state of the seating surface satisfies a predetermined condition; and an action change instruction unit configured to change an action content of the health index calculation unit and / or an action content of the health index output unit in a case where the temperature state of the seating surface is determined by the temperature determination unit to satisfy the predetermined condition.

[0010] According to the present application, in a case where the temperature state of the seating surface is determined by the temperature determination unit to satisfy the predetermined condition, the action content of the health index calculation unit and / or the action content of the health index output unit is changed. Specifically, for example, in a case where the temperature of the seating surface is determined to be less than or equal to 20°C in a cold period of winter, the output of a health index that has a high possibility of not correctly reflecting a health state is stopped, or the output of error information indicating the main point is performed together with (or instead of) the output of the health index that has a high possibility of not correctly reflecting a health state, or the calculation action of the health index calculation unit is corrected in accordance with the temperature state of the seating surface. Thereby, for example, in a case where the user sits on a cold toilet seat or the like in a cold period of winter, a case in which a health index that has a high possibility of not correctly reflecting an actual health state of the user is outputted as a health index that correctly reflects the actual health state can be effectively suppressed.

[0011] Specifically, for example, the temperature determination unit determines whether the temperature state of the seating surface is less than or equal to a predetermined first threshold value (for example, less than or equal to 10°C), and the action change instruction unit preferably stops the output action of the health index output unit in a case where the temperature state of the seating surface is determined by the temperature determination unit to be less than or equal to the first threshold value.

[0012] Thus, a health index having a high possibility of not correctly reflecting the actual health state of the user is not output, and thus, it is possible to effectively suppress a situation in which the user who uses the health index obtained by the toilet system is unnecessarily confused or shaken in, for example, daily health management.

[0013] Alternatively, for example, the temperature determining section determines whether the temperature state of the seat surface is less than or equal to a prescribed second threshold value (for example, less than or equal to 10°C), and the action changing instruction section preferably causes the health index output section to output error information in a case where the temperature state of the seat surface is determined by the temperature determining section to be less than or equal to the second threshold value.

[0014] Thus, error information is output together with (or instead of) a health index having a high possibility of not correctly reflecting the actual health state of the user, and thus, it is possible to effectively suppress a situation in which the user who uses the health index obtained by the toilet system is unnecessarily confused or shaken in, for example, daily health management.

[0015] Alternatively, for example, the temperature determining section determines whether the temperature state of the seat surface is within a prescribed third range (for example, 0°C to 20°C), and the action changing instruction section preferably corrects the calculation action of the health index calculation section (for example, switches a health index calculation program) in a case where the temperature state of the seat surface is determined by the temperature determining section to be within the third range.

[0016] Thus, it is possible to prevent a health index having a high possibility of not correctly reflecting the actual health state of the user from being calculated, and thus, it is possible to effectively suppress a situation in which the user who uses the health index obtained by the toilet system is unnecessarily confused or shaken in, for example, daily health management.

[0017] Information used as a basis for determination by the temperature determining section is, for example, a measurement result of a temperature sensor that measures the temperature of the seat surface. That is, the toilet system of the present application, in a preferred embodiment, further has a temperature sensor that measures the temperature of the seat surface, and the temperature determining section determines whether the temperature state of the seat surface satisfies a prescribed condition based on a measurement result of the temperature sensor.

[0018] Thus, it is possible to directly measure (ascertain) the temperature of the seat surface, and thus, the determination precision involved by the temperature determining section is good.

[0019] Alternatively, information used as a basis for determination by the temperature determination section is, for example, a measurement result of a room temperature sensor that measures the temperature of the surroundings of the seat surface. That is, the toilet system of the present application, in a preferred embodiment, further has a room temperature sensor that measures the temperature of the surroundings of the seat surface, and the temperature determination section determines whether the temperature state of the seat surface meets the prescribed condition based on the measurement result of the room temperature sensor.

[0020] In this case, the temperature of the seat surface can be grasped with a certain degree of accuracy.

[0021] Alternatively, information used as a basis for determination by the temperature determination section is, for example, weather information (particularly, air temperature information) of the region including the house and facilities in which the toilet system is installed. That is, in a preferred embodiment, the temperature determination section determines whether the temperature state of the seat surface meets the prescribed condition based on such weather information. The weather information can be received by the toilet system via the Internet or the like, and can be updated at an appropriate timing.

[0022] In this case, the temperature of the seat surface can be grasped with a certain degree of accuracy.

[0023] Alternatively, information used as a basis for determination by the temperature determination section is, for example, the operation state of a heater that heats the seat surface. Specifically, in the case where the heater is ON, the set specification temperature of the heater (in the case where multiple stages of temperature setting are possible, the set specification temperature of the set stage) can be used as the temperature state of the seat surface in the present application. That is, the toilet system of the present application, in a preferred embodiment, further has a heater that heats the seat surface, and the temperature determination section determines whether the temperature state of the seat surface meets the prescribed condition based on the operation state of the heater.

[0024] In the case where the heater is OFF, the temperature state of the seat surface can be estimated based on a temperature transition curve predicted from the set specification temperature of the heater, for example, in correspondence with the elapsed time since the heater was set OFF. After a sufficient time has elapsed after the heater was set OFF, the aforementioned other information (measurement result by the temperature sensor, measurement result of the room temperature sensor, weather information) can be used as a basis for determination.

[0025] Alternatively, information used as a basis for determination by the temperature determination section is, for example, a measurement result of a timer that measures the time during which the user is seated on the seating surface. Specifically, for example, in a case where the time during which the user is seated exceeds 10 seconds, 36°C (average body temperature) can be used as the temperature state of the seating surface in the present application (an ice-cold seating surface in winter is also heated by the user's body temperature). That is, the toilet system of the present application, in a preferred embodiment, further has a timer that measures the time during which the user is seated on the seating surface, and the temperature determination section determines whether the temperature state of the seating surface meets the prescribed condition based on the measurement result of the timer.

[0026] In addition, the present application is a toilet system characterized by comprising: a toilet seat having a seating surface on which a user is seated; a sensor provided to the toilet seat and measuring a physical quantity that reflects blood flow information of the user; a health index calculation section that calculates a health index of the user based on a measurement result of the sensor; a health index output section that outputs the health index of the user calculated by the health index calculation section; a temperature determination section that determines whether a temperature state of the seating surface meets a prescribed condition; a heater that heats the seating surface; a storage section that stores information on whether the user desires health index output; and a heater control section that changes a drive mode of the heater in a case where it is determined by the temperature determination section that the temperature state of the seating surface meets the prescribed condition and the storage section stores information on the gist that the user desires health index output.

[0027] According to the present application, in a case where it is determined by the temperature determination section that the temperature state of the seating surface meets the prescribed condition and the storage section stores information on the gist that the user desires health index output, the drive mode of the heater is changed. Specifically, for example, in a case where it is determined that the temperature of the seating surface is less than or equal to 20°C in a cold period in winter and the user desires health index output, the heater is set to ON if the heater is OFF, or the set temperature or set temperature step of the heater that is ON is increased (UP) if it is insufficient. Thus, for example, in a case where the user is seated on an ice-cold toilet seat or the like in a cold period in winter, it is possible to effectively suppress a case where a health index that is less likely to correctly reflect the actual health state of the user is output as a health index that correctly reflects the actual health state.

[0028] Further, the present application is a method of providing a health index using a toilet system having: a toilet seat having a seating surface on which a user sits; and a sensor provided to the toilet seat and measuring a physical quantity that reflects blood flow information of the user, characterized by comprising: a health index calculation step of calculating a health index of the user on the basis of a measurement result of the sensor; a health index output step of outputting the health index of the user calculated by the health index calculation step; a temperature determination step of determining whether or not a temperature state of the seating surface satisfies a predetermined condition; and an action change instruction step of changing an action content of the health index calculation step and / or an action content of the health index output step, in a case where it is determined by the temperature determination step that the temperature state of the seating surface satisfies the predetermined condition.

[0029] Further, the present application is a program of providing a health index using a toilet system having: a toilet seat having a seating surface on which a user sits; and a sensor provided to the toilet seat and measuring a physical quantity that reflects blood flow information of the user, characterized by enabling, by execution of the program by a computer, the following steps: a health index calculation step of calculating a health index of the user on the basis of a measurement result of the sensor; a health index output step of outputting the health index of the user calculated by the health index calculation step; a temperature determination step of determining whether or not a temperature state of the seating surface satisfies a predetermined condition; and an action change instruction step of changing an action content of the health index calculation step and / or an action content of the health index output step, in a case where it is determined by the temperature determination step that the temperature state of the seating surface satisfies the predetermined condition.

[0030] Further, the present application is a method of providing an index of health using a toilet system having: a toilet seat having a seating surface on which a user sits; a sensor provided to the toilet seat and measuring a physical quantity that reflects blood flow information of the user; a storage section that stores information on whether the user desires output of an index of health; and a heater that heats the seating surface, characterized by: an index-of-health calculation step of calculating an index of health of the user based on a measurement result of the sensor; an index-of-health output step of outputting the index of health of the user calculated by the index-of-health calculation step; a temperature determination step of determining whether a temperature state of the seating surface meets a prescribed condition; and a heater control step of changing a driving method of the heater in a case where it is determined by the temperature determination step that the temperature state of the seating surface meets the prescribed condition and the storage section stores information on the gist that the user desires output of an index of health.

[0031] Further, the present application is a program of providing an index of health using a toilet system having: a toilet seat having a seating surface on which a user sits; a sensor provided to the toilet seat and measuring a physical quantity that reflects blood flow information of the user; a storage section that stores information on whether the user desires output of an index of health; and a heater that heats the seating surface, characterized by: an index-of-health calculation step of calculating an index of health of the user based on a measurement result of the sensor; an index-of-health output step of outputting the index of health of the user calculated by the index-of-health calculation step; a temperature determination step of determining whether a temperature state of the seating surface meets a prescribed condition; and a heater control step of changing a driving method of the heater in a case where it is determined by the temperature determination step that the temperature state of the seating surface meets the prescribed condition and the storage section stores information on the gist that the user desires output of an index of health.

[0032] Further, the present application is a toilet system characterized by having: a toilet seat having a seating surface on which a user sits; a sensor provided to the toilet seat and measuring a physical quantity that reflects blood flow information of the user; a heater that heats the seating surface; and a heater control section that controls driving of the heater in measurement of the physical quantity by the sensor.

[0033] According to the present application, in the measurement by the sensor, the heater control section controls the driving of the heater, whereby the temperature state of the seating surface on which the user sits can be brought closer to or maintained within the desired temperature range with higher precision, for example.

[0034] Specifically, for example, if the driving of the heater is too small with respect to the room temperature of the toilet (which can occur when the energy saving mode is set, for example), the blood flow state of the user seated on the toilet seat can be affected (causing a change) by the seating surface that is lower than the body temperature (the skin temperature of a person), and conversely, if the driving of the heater is too large (which can occur when the rapid heating mode is set, for example), the blood flow state of the user seated on the toilet seat can be affected (causing a change) by the seating surface that is temporarily higher than the body temperature (the skin temperature of a person).

[0035] Also, it is conceivable that the temperature range that the seating surface should satisfy in order to correctly measure the daily blood flow state of the user is more stringent compared to the temperature range that the seating surface should satisfy in order not to cause discomfort to the user seated on the toilet seat. In the above case, in order for the seating surface to satisfy the latter temperature range (to become a temperature range closer to the body temperature (the skin temperature of a person), for example), the heater control section controls the driving of the heater in the measurement by the sensor is very effective.

[0036] Effects of the Invention

[0037] According to one embodiment of the present application, in a case where the temperature state of the seating surface is determined by the temperature determination section to satisfy a prescribed condition, the action content of the health index calculation section and / or the action content of the health index output section is changed. Specifically, for example, in a case where the temperature of the seating surface is determined to be less than or equal to 20°C in the cold season of winter, the output of a health index that has a high possibility of not correctly reflecting the health state is stopped, or error information indicating this main point is output together with (or instead of) the output of the health index that has a high possibility of not correctly reflecting the health state, or the calculation action of the health index calculation section is corrected in correspondence with the temperature state of the seating surface. Thereby, for example, in a case where the user sits on an ice-cold toilet seat or the like in the cold season of winter, it is possible to effectively suppress a case where a health index that has a high possibility of not correctly reflecting the actual health state of the user is output as a health index that correctly reflects the actual health state.

[0038] Alternatively, according to another aspect of the present application, in a case where the temperature state of the seating surface is determined by the temperature determination section to satisfy the prescribed condition, and the storage section stores information that the user desires the output of the health index, the driving mode of the heater is changed. Specifically, for example, in a case where the temperature of the seating surface is determined to be less than or equal to 20°C in the cold season of winter and the user desires the output of the health index, the heater is set to ON if the heater is OFF, or the set temperature or the set temperature step of the heater that is ON is made to rise (UP) if the set temperature or the set temperature step is insufficient. Thereby, for example, in a case where the user sits on an ice-cold toilet seat or the like in the cold season of winter, it is possible to effectively suppress a case where a health index that has a high possibility of not correctly reflecting the actual health state of the user is output as a health index that correctly reflects the actual health state.

[0039] Alternatively, according to another aspect of the present application, in a case where the temperature state of the seating surface is determined by the temperature determination section to satisfy the prescribed condition, and the storage section stores information that the user desires the output of the health index, the driving mode of the heater is changed. Specifically, for example, in a case where the temperature of the seating surface is determined to be less than or equal to 20°C in the cold season of winter and the user desires the output of the health index, the heater is set to ON if the heater is OFF, or the set temperature or the set temperature step of the heater that is ON is made to rise (UP) if the set temperature or the set temperature step is insufficient. Thereby, for example, in a case where the user sits on an ice-cold toilet seat or the like in the cold season of winter, it is possible to effectively suppress a case where a health index that has a high possibility of not correctly reflecting the actual health state of the user is output as a health index that correctly reflects the actual health state.

[0049] (structure)

[0050] Hereinafter, one embodiment of the present application will be described with reference to the drawings. Figure 1 is a schematic oblique view of a toilet system 10 related to one embodiment of the present application, Figure 2 is an exploded oblique view of a toilet seat 20 of the toilet system 10 of Figure 1 Figure 3 is a schematic block diagram showing a main part of the toilet system 10 of Figure 1

[0051] The toilet system 10 of the present embodiment has a toilet seat 20, a main body 12, and a toilet cover 14 as shown in Figures 1 to 3 The toilet seat 20 and the toilet cover 14 are each pivotally supported with respect to the main body 12 by a shaft.

[0052] In the toilet seat 20, a laser sensor 40 is provided as a sensor that measures a physical quantity that reflects blood flow information of a user, and an electrostatic sensor 50 is provided as a seating sensor. In addition, in the toilet seat 20, a health index calculation unit 60 (specifically, for example, a microprocessor) that calculates a health index of the user on the basis of a measurement result of the laser sensor 40 is provided. Further, in the toilet seat 20 of the present embodiment, a temperature thermistor 65 (one example of a temperature sensor) that measures a temperature of the toilet seat 20 is provided.

[0053] The toilet seat 20 has an opening portion 20a. In the present embodiment, the opening portion 20a of an O-shaped form is formed in a central portion of the toilet seat 20. The opening portion of the toilet seat 20 is not limited to the O-shaped form, and can be a U-shaped form or the like. The outer edge of the toilet seat 20 is curved along the outer shape of the toilet 4. The toilet seat 20 is generally formed of an opaque resin material (for example, polypropylene), and has a seating surface 21 on which a user sits and a bottom surface 25 on the opposite side from the seating surface 21.

[0054] The seating surface 21 is a surface that is exposed upward in a state in which the toilet seat 20 is placed on the upper surface 4b of the toilet 4, and is a surface on which a user sits. The bottom surface 25 is a surface that opposes the upper surface 4b of the toilet 4 in a state in which the toilet seat 20 is lowered. In addition, the toilet seat 20 is composed of a thick wall portion 22 that is formed thick in substantially the entire body, and a thin wall portion 23 that is formed thin in a portion corresponding to the laser sensor 40.

[0055] As​​​Figure 2 As shown, a heater wire 30 (an example of a heater) and heat insulation material 32 are provided inside the toilet seat 20 to heat and keep the seat surface 21 warm. The heater wire 30 is controlled by the toilet seat heating unit 12b provided in the main body 12, and is distributed inside the toilet seat 20 in a manner that does not interfere with the laser sensor 40, the electrostatic sensor 50, the health indicator calculation unit 60, and the temperature thermistor 65. The heat insulation material 32 is disposed below the heater wire 30, the laser sensor 40, the electrostatic sensor 50, the health indicator calculation unit 60, and the temperature thermistor 65.

[0056] The thin-walled portion 23 is of a thickness through which the illumination light from the laser sensor 40 and the reflected light from the user sitting on the seat surface 21 can pass. The thickness of the thin-walled portion 23 is set according to the intensity of the illumination light and reflected light from the laser sensor 40 and the durability of the toilet seat 20, for example, about 0.5 mm to 1.0 mm.

[0057] In this instruction manual, “above,” “below,” “front,” “back,” “left,” and “right” each indicate the direction of view from the back of a user sitting on the toilet seat 20 with the toilet seat 14 open.

[0058] like Figure 2 As shown, the thin-walled portion 23 is formed on the left front side relative to the center of the front-rear length of the opening 20a of the toilet seat 20, and is located on the left front side relative to the center of gravity of the user sitting on the toilet seat 20. As a result, the thin-walled portion 23 is opposite (abutting) to the back side of the left thigh of the user sitting on the toilet seat 20.

[0059] The thin-walled portion 23 is formed to be as small as possible within the range where the laser sensor 40 can detect the blood flow information of the user sitting on the toilet seat 20, for example, it is a circle with a diameter of less than or equal to 12 mm (preferably less than or equal to 8 mm).

[0060] The laser sensor 40 is disposed inside the toilet seat 20 on the back side of the thin-walled portion 23. The laser sensor 40 is a reflective sensor that detects the reflected light (scattered light after Doppler shift caused by red blood cells) reflected in accordance with the blood flow state in the blood vessels under the skin when infrared light is irradiated toward the back side of the user's left thigh. Figure 4 This is a diagram that roughly shows the structure of the laser sensor 40.

[0061] On the other hand, such as Figure 1 and Figure 2As shown, the electrostatic sensor 50 is formed on the right side in front of the center of the length in the front-rear direction of the opening portion 20a of the toilet seat 20, and is located on the front right side compared to the center of gravity position of the user seated on the toilet seat 20. Thus, the electrostatic sensor 50 can detect the seated state when the electrostatic sensor 50 is in contact with the back side of the right thigh of the user seated on the toilet seat 20.

[0062] The health index calculating portion 60 is disposed in the vicinity of the front end of the toilet seat 20 (closer to the laser sensor 40) in the present embodiment, and processes the output signal of the laser sensor 40 to transform it into a signal having a stronger resistance to noise. Specifically, the health index calculating portion 60 calculates the health index (specifically, for example, the number of pulses, pulse variation, blood flow, etc.) of the user seated on the toilet seat 20 based on the measurement result of the laser sensor 40, and transmits a signal corresponding to the calculation result to the communication portion 75 via the control portion 70. Figure 5 is a schematic diagram showing various health index calculation processes based on the measurement result of the laser sensor 40.

[0063] The control portion 70 and the communication portion 75 are disposed in the main body portion 12. The health index calculating portion 60 can also be disposed in the main body portion 12 instead of being disposed in the toilet seat 20. In the case where the health index calculating portion 60 is disposed in the main body portion 12, it can be disposed separately from the control portion 70, or can be integrally disposed as a part of the control portion 70.

[0064] Also, the health index calculating portion 60 and the control portion 70 can not be in the main body portion 12, but can be disposed (constructed) in an external device or in an external network (for example, in the cloud) that communicates via the communication portion 75.

[0065] Returning to Figure 1 The main body portion 12 is located rearward of the bowl portion of the toilet 4, and is installed on the upper surface 4b of the toilet 4. Inside the main body portion 12, an opening and closing unit 12a that controls the opening and closing operation of the toilet seat 20 and the toilet cover 14, a toilet seat heating unit 12b that controls the temperature of the toilet seat 20, a washing unit 12c that performs washing of a part of the human body, and a deodorizing unit 12d that reduces odor components are built in. Each of the units 12a to 12d is centrally controlled by the control portion 70. The control portion 70 of the present embodiment is also connected to each of the electrostatic sensor 50 and the temperature thermistor 65.

[0066] Further, the control section 70 of the present embodiment is connected with a communication section 75 (one example of a health index output section) for outputting the health index of the user calculated by the health index calculation section 60. The communication section 75 transmits the calculated health index of the user to, for example, a remote controller 80 of the toilet room, a portable terminal 85 of the user. Further, the user seated on the toilet seat 20 can confirm various health indexes (vital signs such as the number of pulses, and the like) through a display section 80a of the remote controller 80, a display section 85a of the portable terminal 85.

[0067] Here, as described above, according to the insight of the present inventor, for example, when seated on the cold toilet seat 20 during the cold season of winter, the blood flow of the user seated on the toilet seat 20 becomes poor, and sometimes the health index calculated based on such a blood flow state does not correctly reflect the actual health state.

[0068] In order to cope with this problem, the control section 70 of the toilet system 10 of the present embodiment determines whether the temperature state of the seating surface 21 meets a prescribed condition (functions as a temperature determination section), and changes the contents of the action of the health index calculation section 60 and / or the contents of the action of the communication section 75 (health index output section) when it is determined through the temperature determination that the temperature state of the seating surface 21 meets the prescribed condition described above (functions as an action change instruction section).

[0069] In addition to this, the toilet system 10 of the present embodiment has a timer 95 that measures the continuation time of the seating state of the user in conjunction with the electrostatic sensor 50. The timer 95 is also connected with the control section 70.

[0070] (First Action Example: Details of Configuration)

[0071] With regard to the toilet system 10 configured by the above configuration, the user Figure 6 The first action example will be described.

[0072] In the first action example, the control section 70 functions as a seating determination section, and determines whether the user is seated on the seating surface 21 based on the measurement result of the electrostatic sensor 50 (one example of a seating sensor).

[0073] Further, in the first action example, the control section 70 functions as a seating time determination section, and determines whether the elapsed time from when the user is seated on the seating surface 21 is greater than or equal to 10 seconds based on the measurement result of the timer 95.

[0074] On the other hand, in the first action example, the control section 70 functions as a temperature determination section, and determines whether the temperature state of the seating surface 21 is less than or equal to 20°C (one example of the first threshold value and the second threshold value) based on the measurement result of the temperature thermistor 65 (one example of a temperature sensor).

[0075] Also, in the first action example, the control section 70 functions as an action change instruction section, and in a case where it is determined that the temperature state of the seating surface 21 is less than or equal to 20°C, causes the communication section 75 (health index output section) to output error information and / or stops the output action of the communication section 75 (health index output section).

[0076] Further, the stop of the output action means the stop of the output action related to the health index based on the newly obtained blood flow information, and for example, the health index outputted when the user sat on the seating surface 21 the previous time can continue to be outputted. That is, the stop of the output action includes an action state in which the health index is not newly updated.

[0077] (Action of the first action example)

[0078] Reference Figure 6 First, the control section 70 determines whether the user is seated on the seating surface 21 (STEP 11). If it is determined that the user is not seated on the seating surface 21 (NO in STEP 11), this determination process is repeated.

[0079] If it is determined that the user is seated on the seating surface 21 (YES in STEP 11), the control section 70 next determines whether the temperature state of the seating surface 21 is less than or equal to 20°C (one example of the second threshold value) (STEP 12). In addition, in parallel, the calculation process of the health index of the user performed by the health index calculation section 60 based on the measurement result of the laser sensor 40 is started.

[0080] If the temperature state of the seating surface 21 is not less than or equal to 20°C (NO in STEP 12), a normal action is performed. That is, the communication section 75 transmits the health index of the user calculated by the health index calculation section 60 to, for example, the remote controller 80 of the toilet room and the portable terminal 85 of the user (STEP 13).

[0081] If the temperature state of the seating surface 21 is less than or equal to 20°C (YES in STEP 12), the control section 70 causes the communication section 75 (health index output section) to output error information (STEP 14).

[0082] Then, the control section 70 determines whether the elapsed time from when the user sat on the seating surface 21 is greater than or equal to 10 seconds (STEP 15).

[0083] In a case where the electrostatic sensor 50 detects the dismounting of the user before the elapsed time is greater than or equal to 10 seconds (NO in STEP 15) (YES in STEP 16), the control section 70 stops the output action of the communication section 75 (health index output section) (STEP 18).

[0084] While the elapsed time is not greater than or equal to 10 seconds (NO in STEP 15), the electrostatic sensor 50 does not detect the user's dismounting (NO in STEP 16), and the elapsed time is waited to be greater than or equal to 10 seconds (NO in STEP 16).

[0085] In the case where the elapsed time is greater than or equal to 10 seconds (YES in STEP 15), in the present embodiment, it is determined whether the temperature state of the seating surface 21 is less than or equal to 20°C (one example of the 1st threshold) again on the basis of the measurement result of the temperature thermistor 65 (one example of the temperature sensor) (STEP 17).

[0086] If the temperature state of the seating surface 21 is not less than or equal to 20°C (NO in STEP 17), the normal operation is performed. That is, the communication section 75 transmits the health index of the user calculated by the health index calculation section 60 to, for example, the remote controller 80 of the toilet room and the user's portable terminal 85 (STEP 13).

[0087] If the temperature state of the seating surface 21 is less than or equal to 20°C (YES in STEP 17), the control section 70 stops the output operation of the communication section 75 (the health index output section) (STEP 18).

[0088] (1st Action Example: Effect)

[0089] According to the above 1st action example, for example, in the case where the temperature of the seating surface is less than or equal to 20°C in the cold season of winter, the error information is output from the communication section 75 in the user's seating, and the output of the health index from the communication section 75 is stopped after the user's dismounting. Thereby, it is possible to effectively suppress the case where the health index having a high possibility of not correctly reflecting the actual health state of the user is output as the health index correctly reflecting the actual health state.

[0090] In particular, after the user's dismounting, the health index having a high possibility of not correctly reflecting the actual health state of the user is not output, and thus it is effectively suppressed that the user who uses the health index obtained by the toilet system 10 for, for example, daily health management is unnecessarily confused or shaken.

[0091] Further, in the 1st action example, in the user's seating, the error information is output together with (or instead of) the health index having a high possibility of not correctly reflecting the actual health state of the user, and thus it is effectively suppressed that the user who uses the health index obtained by the toilet system 10 for, for example, daily health management is unnecessarily confused or shaken.

[0092] In addition, in the first operation example, the temperature of the seating surface 21 is directly measured (ascertained) by the temperature thermistor 65, so the determination accuracy at the time of temperature determination is good.

[0093] (First operation example: modification)

[0094] The information used as the basis for temperature determination is not limited to the measurement result of the temperature thermistor 65. For example, a room temperature sensor that measures the temperature of the toilet (the ambient temperature of the seating surface 21) is provided, and in the case where the heater (specifically, the heater wire 30 in the present embodiment) that heats the seating surface 21 becomes OFF, it is possible to determine (infer) whether the temperature state of the seating surface 21 conforms to the prescribed condition on the basis of the measurement result of this room temperature sensor.

[0095] Alternatively, the information used as the basis for temperature determination can be a combination of weather information (particularly, air temperature information) of the region including the house and facilities in which the toilet system 10 is installed and the operation state of the heater. This weather information can be received by the control unit 70 of the toilet system 10 via the Internet or the like by appropriate IOT technology and updated at appropriate timings.

[0096] Alternatively, the information used as the basis for temperature determination can be the operation state of the heater (specifically, the heater wire 30 in the present embodiment) that heats the seating surface 21. Specifically, in the case where the heater becomes ON, it is possible to use the set specification temperature (in the case where multiple steps of temperature setting are possible, the set specification temperature of the set step) of the heater as the temperature state of the seating surface 21 for determination. Also, even in the case where the heater becomes OFF, it is possible to infer the temperature state of the seating surface on the basis of the temperature transition curve predicted from the set specification temperature of the heater, for example, in accordance with the elapsed time from when the heater became OFF, for determination. In this case, after a sufficient time has elapsed after the heater became OFF, the aforementioned other information (measurement result by the temperature sensor, measurement result of the room temperature sensor, weather information) can be used as the basis for determination.

[0097] Alternatively, the information used for temperature determination can be the measurement result of the timer 95 that measures the time during which the user is seated on the seating surface 21. Specifically, for example, in the case where the seating time of the user exceeds 10 seconds, it is possible to use 36°C (the average body temperature) as the temperature state of the seating surface 21 for determination (an ice-cold seating surface 21 in winter is also heated by the body temperature of the user). That is, in the first operation example of the present embodiment, if STEP 15 is YES, then STEP 17 can be automatically determined to be YES. Figure 5

[0098] ​(Action example 2: details of the structure)

[0099] With the aforementioned toilet system 10, the use Figure 7 The action example 2 will be described.

[0100] In the action example 2, the control section 70 also functions as a seating determination section, and determines whether the user is seated on the seating surface 21 based on the measurement result of the electrostatic sensor 50 (one example of a seating sensor).

[0101] In addition, in the action example 2, the control section 70 functions as a temperature determination section, and determines whether the temperature state of the seating surface 21 is in the range of 0°C to 10°C (one example of the third range), or in the range of 10°C to 20°C (another example of the third temperature range), or outside of these temperature ranges (i.e., 20°C or more) based on the measurement result of the temperature thermistor 65 (one example of a temperature sensor).

[0102] Furthermore, in the action example 2, the control section 70 functions as an action change instruction section, and changes the action content of the health index calculation section 60 in the case where it is determined that the temperature state of the seating surface 21 is in the range of 0°C to 10°C, or in the range of 10°C to 20°C. Specifically, in the health index calculation section 60, the calculation formula used in the calculation process (refer to Figure 5 ) of the health index based on the output signal of the laser sensor 40 is switched from the normal calculation formula (in the case of 20°C or more) to the low-temperature calculation formula (in the case of 10°C to 20°C) or the extremely low-temperature calculation formula (in the case of 0°C to 10°C). (The low-temperature calculation formula and the extremely low-temperature calculation formula are prepared in the health index calculation section 60 in advance so as to be switchable.)

[0103] (Action example 2: effects)

[0104] Referring to Figure 7 , the control section 70 first determines whether the user is seated on the seating surface 21 (STEP 21). If it is determined that the user is not seated on the seating surface 21 (NO in STEP 21), this determination process is repeated.

[0105] If it is determined that the user is seated on the seating surface 21 (YES in STEP 21), the control section 70 next determines whether the temperature state of the seating surface 21 is in the range of 0°C to 10°C (one example of the third range), or in the range of 10°C to 20°C (another example of the third threshold), or outside of these temperature ranges (i.e., 20°C or more) (STEP 22). In addition, in parallel, the calculation process of the health index of the user by the health index calculation section 60 based on the measurement result of the laser sensor 40 is started.

[0106] In a case where the temperature state of the seating surface 21 is not in the set temperature range (i.e., greater than or equal to 20°C) (NO in STEP 22), a normal action is implemented. That is, the communication section 75 transmits the health index of the user calculated by the health index calculation section 60 to, for example, the remote controller 80 of the toilet room, the portable terminal 85 of the user (STEP 23).

[0107] In a case where it is determined that the temperature state of the seating surface 21 is in the range of 0°C to 10°C or in the range of 10°C to 20°C (YES in STEP 22), the control section 70 controls the health index calculation section 60 to change the action content of the health index calculation section 60 (STEP 24). Specifically, in the health index calculation section 60, the calculation formula used in the calculation process of the health index based on the output signal of the laser sensor 40 is switched from the normal calculation formula (in the case of greater than or equal to 20°C) to the calculation formula for low temperature (in the case of 10°C to 20°C) or the calculation formula for extremely low temperature (in the case of 0°C to 10°C). Figure 5

[0108] Then, the health index calculation section 60 after the calculation formula is switched again implements (calculates) the calculation process of the health index of the user (resetting can be performed once as necessary). Also, the control section 70 confirms the health index calculated after the calculation formula is switched (after the action content is changed) (STEP 25).

[0109] During a case where the result of the confirmation is not YES (NO in STEP 25), the result of the confirmation is waited for to be YES (NO in STEP 25).

[0110] After the result of the confirmation is YES (YES in STEP 25), the communication section 75 transmits the health index of the user calculated by the health index calculation section 60 after the calculation formula is switched (after the action content is changed) to, for example, the remote controller 80 of the toilet room, the portable terminal 85 of the user (STEP 26).

[0111] (2nd Action Example: Effect)

[0112] According to the above 2nd action example, for example, in a case where the temperature of the seating surface is in the range of 0°C to 10°C or in the range of 10°C to 20°C during the cold period of winter, the calculation process of the health index based on the output signal of the laser sensor 40 is changed (STEP 24). Figure 5 ​The calculation formula used in the above-described formula (1) is switched from a general calculation formula (for a case where the temperature is greater than or equal to 20°C) to a calculation formula for low temperatures (for a case where the temperature is from 10°C to 20°C) or a calculation formula for extremely low temperatures (for a case where the temperature is from 0°C to 10°C). Thus, it is possible to effectively suppress a case where a health index having a high possibility of not correctly reflecting the actual health state of the user is output as a health index that correctly reflects the actual health state.

[0113] In the second operation example, the temperature of the seating surface 21 is also directly measured (monitored) by the temperature thermistor 65, and thus the determination accuracy at the time of temperature determination is good.

[0114] (Second Operation Example: Modified Example)

[0115] In the second operation example, the information used as a basis for temperature determination is not limited to the measurement result of the temperature thermistor 65. For example, a room temperature sensor that measures the temperature of the toilet (the ambient temperature of the seating surface 21) is provided, and in a case where the heater (specifically, the heater wire 30 in the present embodiment) that heats the seating surface 21 is OFF, it is possible to determine (infer) whether the temperature state of the seating surface 21 conforms to the prescribed condition on the basis of the measurement result of the room temperature sensor.

[0116] Alternatively, the information used as a basis for temperature determination can be a combination of weather information (particularly, air temperature information) of the region including the house and facilities in which the toilet system 10 is installed and the operation state of the heater. The weather information can be received by the control unit 70 of the toilet system 10 via the Internet or the like by an appropriate IOT technology and updated at an appropriate timing.

[0117] Alternatively, the information used as a basis for temperature determination can be the operation state of the heater (specifically, the heater wire 30 in the present embodiment) that heats the seating surface 21. Specifically, in a case where the heater is ON, it is possible to use the set specification temperature of the heater (the set specification temperature of the set gear in a case where temperature setting in multiple gears is possible) as the temperature state of the seating surface 21 for determination. Also, even in a case where the heater is OFF, it is possible to infer the temperature state of the seating surface on the basis of a temperature transition curve predicted from the set specification temperature of the heater in accordance with, for example, the elapsed time since the heater was turned OFF and use it for determination. In this case, the aforementioned other information (measurement result by the temperature sensor, measurement result of the room temperature sensor, weather information) can be used as a basis for determination after a sufficient time has elapsed after the heater was turned OFF.

[0118] Alternatively, the information used for the temperature determination can be a measurement result of a timer that measures the time for which the user is seated on the seating surface 21. Specifically, for example, in a case where the user's seating time exceeds 10 seconds, 36°C (average body temperature) can be used for the determination as the temperature state of the seating surface 21 (an ice-cold seating surface 21 in winter is also heated by the user's body temperature).

[0119] (Action Example 3: Details of Configuration)

[0120] With regard to the aforementioned toilet system 10, the use Figure 8 The Action Example 3 will be described.

[0121] In the Action Example 3, the control section 70 also functions as a seating determination section, and determines whether or not the user is seated on the seating surface 21, based on the measurement result of the electrostatic sensor 50 (one example of a seating sensor).

[0122] In addition, in the Action Example 3, the control section 70 also functions as a temperature determination section, and determines whether or not the temperature state of the seating surface 21 is less than or equal to 20°C (one example of the first threshold value and the second threshold value), based on the measurement result of the temperature thermistor 65 (one example of a temperature sensor).

[0123] Further, in the Action Example 3, the control section 70 also functions as an action change instruction section, and causes the communication section 75 (health index output section) to output error information, and / or stops the output action of the communication section 75 (health index output section), in a case where it is determined that the temperature state of the seating surface 21 is less than or equal to 20°C.

[0124] On the other hand, in the Action Example 3, the control section 70 functions as an action change instruction section, and forcibly drives the heater wire 30 (one example of a heater) and / or increases the set temperature (functions as a heater control section), in a case where it is determined that the temperature state of the seating surface 21 is less than or equal to 20°C, and information that the user desires the health index output is stored in the storage section 97 (may be provided in the main body section 12 (refer to Figure 3 , and / or a storage section in a remote controller 80, external instrument (user's portable terminal, etc.) connected via the communication section 75).

[0125] (Action Example 3: Effects)

[0126] With reference to Figure 8 , the control section 70 first determines whether or not the user is seated on the seating surface 21 (STEP 31). If it is determined that the user is not seated on the seating surface 21 (NO in STEP 31), the determination process is repeated.

[0127] If it is determined that the user is seated on the seating surface 21 (YES in STEP 31), the control section 70 next determines whether the temperature state of the seating surface 21 is less than or equal to 20°C (an example of the 2nd threshold value) (STEP 32). In addition, in parallel, the process of calculating the health index of the user by the health index calculation section 60 based on the measurement result of the laser sensor 40 is started.

[0128] If the temperature state of the seating surface 21 is not less than or equal to 20°C (NO in STEP 32), a normal operation is performed. That is, the communication section 75 transmits the health index of the user calculated by the health index calculation section 60 to, for example, the remote controller 80 of the toilet room, the portable terminal 85 of the user (STEP 33).

[0129] If the temperature state of the seating surface 21 is less than or equal to 20°C (YES in STEP 32), the control section 70 causes the communication section 75 (health index output section) to output error information (STEP 34).

[0130] Then, the control section 70 determines whether the storage section 97 stores information of the gist that the user desires the health index output (STEP 35).

[0131] In the case where the gist that the user desires the health index output is not confirmed (NO in STEP 35), the control section 70 stops the output operation of the communication section 75 (health index output section) (STEP 36).

[0132] On the other hand, in the case where the gist that the user desires the health index output is confirmed (YES in STEP 35), the control section 70 forcibly drives the heater wire 30 (an example of a heater) and / or increases the set temperature via the toilet seat heating unit 12b (STEP 37). Then, the control process returns to STEP 32.

[0133] Further, in the case where the temperature state of the seating surface 21 is not less than or equal to 20°C (NO in STEP 32), the output of the temperature thermistor 65 (an example of a temperature sensor) is monitored by the control section 70 in a manner that the condition continues until the measurement by at least the laser sensor 40 ends, and based on the monitoring result, the heater (specifically, the heater wire 30 in the present embodiment) that heats the seating surface 21 as needed is controlled (set to ON, set to UP (increase the set temperature level), set to DOWN (decrease the set temperature level), set to OFF, and the like are appropriately combined) by the control section 70.

[0134] (3rd operation example: effects)

[0135] According to the above 3rd action example, for example, in a case where the temperature of the seat surface is less than or equal to 20°C in the cold season of winter and the user desires the health index to be output, the heater wire 30 is set to ON if the heater wire 30 is OFF, or the setting temperature or setting temperature stage of the heater wire 30 that is ON is raised (UP) if it is insufficient. Thus, it is possible to effectively suppress a case where a health index that is highly likely not to correctly reflect the actual health state of the user is output as a health index that correctly reflects the actual health state.

[0136] On the other hand, for example, in a case where the temperature of the seat surface is less than or equal to 20°C in the cold season of winter and the user does not desire the health index to be output, the health index is not output, and thus it is possible to effectively suppress a case where unnecessary confusion or wavering is caused to the user who uses the health index obtained by the toilet system 10 for, for example, daily health management.

[0137] In addition, in the 3rd action example, the temperature of the seat surface 21 is also directly measured (grasped) by the temperature thermistor 65, and thus the determination accuracy at the time of temperature determination is good.

[0138] (3rd Action Example: Modified Example)

[0139] In the 3rd action example, the information used as a basis for temperature determination is not limited to the measurement result of the temperature thermistor 65. For example, a room temperature sensor that measures the temperature of the toilet (the temperature of the surroundings of the seat surface 21) is provided, and in a case where the heater (specifically, the heater wire 30 in the present embodiment) that heats the seat surface 21 is OFF, it is possible to determine (infer) whether or not the temperature state of the seat surface 21 conforms to the prescribed condition on the basis of the measurement result of the room temperature sensor.

[0140] Alternatively, the information used as a basis for temperature determination can be a combination of weather information (particularly, air temperature information) of the region including the house and facilities in which the toilet system 10 is installed and the operation state of the heater. The weather information can be received by the control unit 70 of the toilet system 10 via the Internet or the like by an appropriate IOT technique, and is updated at an appropriate timing.

[0141] Alternatively, the information used as the basis for temperature determination can be the operating state of the heater (specifically, heater line 30 in this embodiment) that heats the seating surface 21. Specifically, when the heater is ON, the set temperature of the heater (or the set temperature of the set temperature if multiple temperature settings are possible) can be used as the temperature state of the seating surface 21 for determination. Furthermore, even when the heater is OFF, the temperature state of the seating surface can be estimated, for example, based on a temperature shift curve predicted according to the set temperature of the heater, corresponding to the elapsed time since the heater became OFF, and used for determination. In this case, after a sufficient time has elapsed since the heater became OFF, the aforementioned other information (measurement results obtained by the temperature sensor, measurement results by the room temperature sensor, and meteorological information) can be used as the basis for determination.

[0142] (Example of the third action: Other variations)

[0143] In the third example of operation, the calculation process of the user's health indicators by the health indicator calculation unit 60 based on the measurement results of the laser sensor 40 begins in parallel with STEP 32. Moreover, if the temperature of the seating surface 21 is not less than or equal to 20°C (NO in STEP 32), it is preferable to continue this condition until at least the measurement by the laser sensor 40 is completed. The output of the temperature thermistor 65 is monitored by the control unit 70, and preferably, based on the monitoring results, the heater that heats the seating surface 21 as needed is controlled by the control unit 70.

[0144] In contrast, Figure 9 In other variations of the third operation example shown, when the temperature of the seating surface 21 is not less than or equal to 20°C (NO in STEP 32), the heater (specifically, heater line 30 in this embodiment) that heats the seating surface 21 in a temperature range close to or maintained near body temperature (human skin temperature) is controlled by the control unit 70 (set to ON, set to UP (set temperature level up), set to DOWN (set temperature level down), set to OFF, etc., are appropriately combined). Furthermore, while the heater is driven to a temperature range near body temperature as described above, a measurement performed by the laser sensor 40 is conducted, and the calculation process of the user's health indicators by the health indicator calculation unit 60 based on the measurement results of the laser sensor 40 begins.

[0145] According to the other modification of the above-mentioned Action 3, in the measurement by the laser sensor 40, the control section 70 controls the driving of the heater so that the temperature state of the seating surface 21 on which the user sits approaches or is maintained in the temperature range near the body temperature.

[0146] Thus, it is possible to effectively prevent the case where the blood flow state of the user seated on the toilet seat is affected (causes a change) by the seating surface that is lower than the body temperature (the skin temperature of a person) in the case where the driving of the heater is too small with respect to the room temperature of the toilet room, and, on the contrary, it is possible to effectively prevent the case where the blood flow state of the user seated on the toilet seat is affected (causes a change) by the seating surface that is temporarily higher than the body temperature (the skin temperature of a person) in the case where the driving of the heater is too large with respect to the room temperature of the toilet room.

[0147] Further, it is preferable that, during the implementation of the heater driving control to the temperature range near the body temperature as mentioned above, even in the case where the remote controller 80 of the toilet room, the portable terminal 85 of the user is provided with a function capable of manually changing the temperature setting of the heater or the like, the provision of the function is interrupted (for example, manual input is not accepted).

[0148] (Supplement related to the program)

[0149] The various functions of the health index calculation section 60, the control section 70, and the communication section 75 can be implemented by a microcomputer or the like that executes a corresponding program. The program and the storage medium that stores the program are also the objects of the present application.

[0150] For example, the program related to the present application provides a health index using the toilet system 10 having: a toilet seat 20 having a seating surface 21 on which a user sits; and a laser sensor 40 provided to the toilet seat 20 and measuring a physical quantity that reflects blood flow information of the user, and the program is characterized in that, by executing the program by a computer, the following processes can be implemented: a health index calculation process of calculating a health index of the user based on the measurement result of the laser sensor 40; a health index output process of outputting the health index of the user calculated by the health index calculation process; a temperature determination process of determining whether or not the temperature state of the seating surface 21 meets a prescribed condition; and an action change instruction process of changing the action content of the health index calculation process or the action content of the health index output section in the case where it is determined by the temperature determination process that the temperature state of the seating surface 21 meets the prescribed condition.

[0151] Alternatively, the program according to the present application provides an index of health using a toilet system 10 having: a toilet seat 20 having a seating surface 21 on which a user sits; a laser sensor 40 provided to the toilet seat 20 and measuring a physical quantity that reflects blood flow information of the user; and a heater wire 30 that heats the seating surface 21, the program being characterized in that, by executing the program by a computer, the following processes are implemented: a health index calculation process that calculates an index of health of the user based on a measurement result of the laser sensor 40; a health index output process that outputs the index of health of the user calculated by the health index calculation process; a temperature determination process that determines whether a temperature state of the seating surface 21 meets a prescribed condition; and a heater control process that changes a driving method of the heater wire 30 in a case where it is determined by the temperature determination process that the temperature state of the seating surface 21 meets the prescribed condition.

[0152] Alternatively, the program according to the present application provides an index of health using a toilet system 10 having: a toilet seat 20 having a seating surface 21 on which a user sits; a laser sensor 40 provided to the toilet seat 20 and measuring a physical quantity that reflects blood flow information of the user; a storage section 97 that stores information on whether the user desires output of the index of health; and a heater wire 30 that heats the seating surface 21, the program being characterized in that, by executing the program by a computer, the following processes are implemented: a health index calculation process that calculates an index of health of the user based on a measurement result of the laser sensor 40; a health index output process that outputs the index of health of the user calculated by the health index calculation process; a temperature determination process that determines whether a temperature state of the seating surface 21 meets a prescribed condition; and a heater control process that changes a driving method of the heater wire 30 in a case where it is determined by the temperature determination process that the temperature state of the seating surface 21 meets the prescribed condition and the storage section 97 stores information on the user's desire for output of the index of health.
