[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the following description, the front-to-back direction as seen from a user seated on the toilet seat 12 is referred to as the front-to-back direction. The left-to-right direction as seen from a user seated on the toilet seat 12 is referred to as the left-to-right direction. The up-to-down direction is the direction perpendicular to the floor surface on which the toilet bowl 11 is placed.

[0009] The toilet device 1 of the first embodiment is a device for managing women's health by measuring the woman's body temperature daily using a body temperature sensor 14 attached to the toilet seat 12 while the female user is seated on the toilet seat 12, and based on the female user's body temperature measured daily, estimates menstrual and ovulation information related to the woman's menstruation and ovulation, i.e., the woman's specific menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period, and reports the estimated menstruation start date, estimated menstruation end date, estimated menstrual cycle, estimated ovulation date, estimated PMS start date, estimated PMS end date, and estimated PMS period. The toilet device 1 also has a function of estimating past ovulation dates and reporting the estimated past ovulation dates based on the female user's body temperature measured daily.

[0010] As shown in Figures 1 and 2, the toilet system 10 includes a toilet device 1 and a remote control terminal 17 (alarm unit). The toilet device 1 is placed in a toilet room 100. A door 101 that is opened and closed when a person enters or leaves the toilet room 100 is attached to the front side of the toilet device 1. The toilet device 1 includes a toilet bowl 11, a toilet seat 12, a toilet lid 13, a body temperature measurement sensor 14, an entry sensor 15, a seating sensor 16, and a control unit 18 (see Figure 2). The toilet seat 12 forms a seating area on which a person sits. The toilet device 1 includes an ovulation estimation device 2. The ovulation estimation device 2 includes the body temperature measurement sensor 14 and the control unit 18. The ovulation prediction device 2 measures the woman's body temperature daily using a body temperature measurement sensor 14 provided on the toilet seat 12, and based on the female user's body temperature measured daily, predicts menstrual and ovulation information related to the woman's menstruation and ovulation, i.e., the woman's specific menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period, and predicts the estimated menstruation start date, estimated menstruation end date, estimated menstrual cycle, estimated ovulation date, estimated premenstrual syndrome (PMS) start date, estimated PMS end date, and estimated PMS cycle. In this embodiment, the control unit 18 serves as both the control unit of the toilet device 1 and the control unit of the ovulation prediction device 2.

[0011] As shown in Figure 1, the toilet bowl 11 is made of, for example, ceramic and has an opening facing upward. A toilet seat 12 and a toilet lid 13 are disposed on the top of the toilet bowl 11, and the toilet seat 12 and the toilet lid 13 are attached to the toilet bowl 11 so as to be rotatable.

[0012] The toilet seat 12 is the part on which a user sits, and is placed on top of the toilet bowl 11. The toilet seat 12 is formed in a ring shape with an opening 121 on the inside. The toilet lid 13 is a lid that can open and close and cover the opening 121 of the toilet bowl 11 and the toilet seat 12. The toilet seat 12 is formed from a resin material.

[0013] A body temperature measurement sensor 14 is provided on the surface of the toilet seat 12. The body temperature measurement sensor 14 measures the body temperature of a person sitting on the toilet seat 12. For example, the body temperature measurement sensor 14 measures the skin temperature of the person sitting on the toilet seat 12 and estimates the body temperature from that skin temperature. The body temperature measurement sensor 14 has a pair of detection units 141, one on each side. The detection units 141 are the parts of the body temperature measurement sensor 14 that detect the body temperature of the person. The pair of detection units 141 are each provided in a portion near the rear of the annular portion of the toilet seat 12. When a woman sits on the toilet seat 12, the pair of detection units 141 are positioned below the thighs of the female user.

[0014] For example, when a woman is seated on the toilet seat 12, the pair of detecting units 141 are preferably positioned so that they are located on the lower part of the woman's thighs, 3 to 10 cm in front of the end of the rear side (the boundary between the thighs and buttocks). For example, when a woman is seated on the toilet seat 12, the pair of detecting units 141 are more preferably positioned so that they are located on the lower part of the woman's thighs, 5 cm in front of the end of the rear side (the boundary between the thighs and buttocks). The lower part, 3 to 10 cm in front of the end of the rear side (the boundary between the thighs and buttocks), is a position where the pair of detecting units 141 can be stably in contact with the woman's thighs and can stably measure the body temperature of a female user.

[0015] Detector 141 of this embodiment has, for example, a thermistor, and is formed, for example, in a circular shape in a plan view as shown in Fig. 1, and is built into the interior of toilet seat 12. Note that detector 141 is not limited to being circular in a plan view, and may be formed, for example, in a triangular, rectangular, or elongated shape in a plan view. Furthermore, detector 141 is not limited to being built into the interior of toilet seat 12, and may be provided exposed to the outside on the upper surface of toilet seat 12.

[0016] 3, the detection unit 141 of the body temperature measurement sensor 14 is positioned closer to the opening 121 than the central imaginary line L that extends along the center of the width of the annular portion of the toilet seat 12 in a plan view, and is thereby positioned closer to the opening 121 side of the toilet seat 12 with respect to the central imaginary line L that extends along the center of the width of the annular portion of the toilet seat 12. In this embodiment, the detection unit 141 of the body temperature measurement sensor 14 is positioned so that the area S1 of the detection unit 141 of the body temperature measurement sensor 14 that is positioned in region A on the opening 121 side of the toilet seat 12 with respect to the central imaginary line L that extends along the center of the width of the annular portion of the toilet seat 12 is equal to or greater than the area S2 of the detection unit 141 of the body temperature measurement sensor 14 that is positioned in region B opposite the opening 121 of the toilet seat 12.

[0017] The position where the detection unit 141 of the body temperature sensor 14 is disposed will be described in detail. In Figure 3, the detection unit 141A of the body temperature sensor 14 is shown by a virtual line. The center of the detection unit 141A of the body temperature sensor 14 shown by a virtual line in Figure 3 is disposed on a central virtual line L that extends along the center of the width of the annular part of the toilet seat 12. The detection unit 141A of the body temperature sensor 14 shown by a virtual line in Figure 3 illustrates a case where, in a plan view, the area S1 of the area A side of the detection unit 141 of the body temperature sensor 14 that is disposed in area A on the opening 121 side of the toilet seat 12 and the area S2 of the area B side of the detection unit 141 of the body temperature sensor 14 that is disposed in area B opposite the opening 121 of the toilet seat 12 have equal area ratios relative to the central virtual line L that extends along the center of the width of the annular part of the toilet seat 12 (area S1 = area S2).

[0018] In this embodiment, the detection unit 141A of the body temperature measurement sensor 14 is preferably positioned closer to the opening 121 of the toilet seat 12 with respect to the central imaginary line L extending along the center of the width direction of the annular portion of the toilet seat 12, and is therefore preferably positioned closer to the opening 121 than the position of the detection unit 141A of the body temperature measurement sensor 14 shown by the imaginary line in Figure 3, and is positioned so that the area S1 of the detection unit 141A of the body temperature measurement sensor 14 positioned in area A on the opening 121 side of the toilet seat 12 is equal to or greater than the area S2 of the detection unit 141A of the body temperature measurement sensor 14 positioned in area B opposite the opening 121 of the toilet seat 12 (area S1 ≧ area S2).

[0019] When measuring body temperature for health management specific to women, women, who are the primary subjects for body temperature measurement using the body temperature sensor 14, are smaller on average than men, and therefore their center of gravity when seated on the toilet seat 12 is positioned closer to the inside of the toilet seat 12. Therefore, by positioning the detection unit 141 of the body temperature sensor 14 closer to the opening 121 of the toilet seat 12 with respect to the imaginary central line L that extends along the center of the width of the annular part of the toilet seat 12 in a plan view, when used by a woman whose center of gravity when seated on the toilet seat 12 is positioned closer to the inside of the toilet seat 12, it is possible to increase the adhesion of the detection unit 141 of the body temperature sensor 14 to the thighs of the female user, and to accurately measure the body temperature of the female user.

[0020] As shown in Figures 3 and 4, the body temperature sensor 14 is built into the toilet seat 12 and is disposed in a sensor placement portion 122 of the toilet seat 12. The toilet seat 12 has the sensor placement portion 122 in which the detection unit 141 of the body temperature sensor 14 is disposed, and the sensor placement portion 122 is formed to be raised higher than the surface of the surrounding area 123 of the sensor placement portion 122 on the toilet seat 12. By disposing the body temperature sensor 14 in the sensor placement portion 122 that is raised higher than the surrounding area 123, it is possible to improve adhesion to the thighs of female users and accurately measure the body temperature of female users. Note that the raised portion of the sensor placement portion 122 is preferably formed to be raised with a gently sloping surface so as not to impair the design. However, the raised portion of the sensor placement portion 122 is not limited to being formed to be raised with a gently sloping surface.

[0021] 4, the thickness of the resin material of the sensor arrangement portion 122 where the detection portion 141 of the body temperature sensor 14 is arranged is thinner than the thickness of the portion 123 surrounding the detection portion 141 of the body temperature sensor 14. As a result, the sensor arrangement portion 122 where the body temperature sensor 14 is arranged in the toilet seat 12 is thinner, which improves the heat conduction performance to the detection portion 141 of the body temperature sensor 14.

[0022] As shown in Figure 5, an electric heating wire 145 (heating unit) for the heater is housed in a routed state inside the toilet seat 12. The detection unit 141 of the body temperature measurement sensor 14 is arranged in a position that does not overlap the electric heating wire 145 (heating unit) for the heater housed inside the toilet seat 12, when viewed from above the toilet seat 12. This allows the body temperature measurement sensor 14 to be placed in a position that is less susceptible to the heat of the electric heating wire 145, thereby reducing errors in body temperature measurement due to the influence of the electric heating wire 145 and improving the accuracy of body temperature measurement.

[0023] The toilet seat 12 is formed containing a resin material, and the thermal conductivity of the entire toilet seat 12, or the thermal conductivity of only the resin portion around the detection unit 141 of the body temperature sensor 14, is higher than 0.125 W / mK. Since the resin material generally used for toilet seats 12 is polypropylene (PP), it is preferable that the thermal conductivity of the entire toilet seat 12, or the thermal conductivity of only the resin portion around the detection unit 141 of the body temperature sensor 14, is higher than the thermal conductivity of polypropylene (PP), which is 0.125 W / mK. Note that a thermal conductivity higher than 0.125 W / mK may refer to the inherent value of the thermal conductivity of the resin material of the toilet seat 12 itself, or it may refer to the thermal conductivity value of a resin material mixed with a highly conductive material.

[0024] As a result, by making the thermal conductivity of the entire toilet seat 12, or just the resin portion around the detection unit 141 of the body temperature measurement sensor 14, higher than 0.125 W / mK, the thermal conductivity can be made higher than that of polypropylene (PP), a resin material generally used for toilet seats 12, and therefore when a female user sits on the toilet seat 12, heat can be more easily transferred to the detection unit 141 of the body temperature measurement sensor 14. Note that the toilet seat 12 does not have to be made of a resin material.

[0025] As shown in FIG. 1, the toilet seat 12 has a first portion 124 around the detection unit 141 of the body temperature sensor 14, and a second portion 125 other than the area around the body temperature sensor 14. In this embodiment, the first portion 124 is the area around the detection unit 141 of the body temperature sensor 14, and as shown in FIG. 4, includes a sensor arrangement portion 122 where the detection unit 141 of the body temperature sensor 14 is arranged and an area 123 around the detection unit 141 of the body temperature sensor 14. As shown in FIG. 1, the second portion 125 is the area around the body temperature sensor 14 other than the first portion 124. The thermal conductivity of the first portion 124 (see FIGS. 1 and 4) may be higher than the thermal conductivity of the second portion 125 (see FIG. 1). This makes it easier for heat to be transferred to the detection unit 141 of the body temperature sensor 14 around the detection unit 141 of the body temperature sensor 14 when a female user sits on the toilet seat 12.

[0026] The entry sensor 15 is composed of, for example, an infrared sensor, an ultrasonic sensor, or the like, and is provided inside the toilet room 100 as shown in FIG. 1 , and detects that a person has entered the toilet room 100 when that person has entered the toilet room 100. The entry sensor 15 is attached to the rear wall inside the toilet room. Note that the location where the entry sensor 15 is provided is not limited to this. The entry sensor 15 may be attached in any position where it can detect that a person has entered the toilet room 100 when that person has entered, and may be provided, for example, in a position behind the toilet seat 12 in the toilet device 1 (for example, near where the seat sensor 16, which will be described later, is provided). The entry sensor 15 may also be a sensor for detecting whether the door 101 is open or closed, and may include, for example, a magnetic switch, an infrared sensor, or an ultrasonic sensor.

[0027] The seating sensor 16 is provided at a position behind the toilet seat 12 in the toilet device 1. The seating sensor 16 has, for example, an infrared sensor or an electrostatic sensor, and detects that a person has sat on the toilet seat 12 by switching from OFF to ON, and detects that the person has left the toilet seat 12 by switching from ON to OFF. The position at which the seating sensor 16 is provided is not limited to this, and it may be provided on the toilet seat 12, for example.

[0028] The remote control terminal 17 is attached to one of the walls in the left-right direction of the toilet device 1 inside the toilet room 100. The remote control terminal 17 is a terminal that can perform various operations. The remote control terminal 17 is also provided outside the toilet device 1, and functions as a receiving unit that receives inferred information inferred by an inferring unit 182 (described later) of the control unit 18, and also has a notification function that notifies a female user (person) present inside the toilet room 100. Examples of the notification function of the remote control terminal 17 include displaying on a display unit of the remote control terminal 17 and notifying by voice.

[0029] The control unit 18 controls various operations of the toilet device 1. As shown in Fig. 2, the control unit 18 has an identification function unit 181, an estimation unit 182, and a notification control unit 183 (transmission unit). The identification function unit 181, the estimation unit 182, and the notification control unit 183 constitute a part of the ovulation estimation device 2.

[0030] The identification function unit 181 has an identification function for identifying an individual. Since the home toilet device 1 is shared by a family, the identification function unit 181 identifies the individual female user.

[0031] By identifying female users, the identification function unit 181 can individually manage, for each identified female user, menstrual and ovulation information regarding the woman's menstruation and ovulation, that is, at least one of the following information: menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period, and can notify the identified female user.

[0032] For example, the identification function of the identification function unit 181 to identify an individual user may include identifying an individual from biometric information such as face, fingerprint, voiceprint and veins, identifying an individual by operating an operation panel, identifying an individual using a card key equipped with an identification function, identifying an individual user using the communication function of a mobile terminal such as a smartphone, or identifying an individual based on the characteristics of how the user sits on the toilet seat.

[0033] In the case of a woman living alone, or in the case where there are multiple toilet devices in a house and one of them is used only by a female user, the identification function of the identification function unit 181 can be set to not function. In this case, when a person sits on the toilet seat 12, the body temperature of the person sitting on the toilet seat 12 is measured without identifying the user, and based on the person's body temperature measured over multiple days by the body temperature measurement sensor 14, one or more of the menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period can be estimated and notified.

[0034] The estimation unit 182 estimates one or more of the menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period based on the person's body temperature measured over multiple days by the body temperature measurement sensor 14. This allows a female user to estimate one or more of the menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period. Therefore, by simply sitting on the toilet seat 12 every day, it is possible to easily estimate one or more of the menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period. Regarding ovulation date, the estimation unit 182 can estimate future ovulation dates and past ovulation dates based on the female user's body temperature measured daily.

[0035] The prediction of the start date of menstruation, ovulation, and premenstrual syndrome (PMS) is based on the basal body temperature method, using the user's accumulated body temperature data measured daily.

[0036] The basal body temperature method is a method of predicting the ovulation period by measuring basal body temperature. As shown in Figure 6, a woman's basal body temperature is in a low temperature period from the menstrual period to the ovulation period, and is in a high temperature period from the ovulation period to the menstrual period. The basal body temperature method is a method of measuring body temperature as basal body temperature every day and predicting the ovulation period using the periodicity of this basal body temperature. In this embodiment, in association with the user's daily use of the toilet device 1, the basal body temperature method is used to predict the menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period by measuring the body temperature when the user sits on the toilet seat every morning when using the toilet device 1.

[0037] Specifically, when using the basal body temperature method to estimate the start date of menstruation, the end date of menstruation, the menstrual cycle, the day of ovulation, the start date of premenstrual syndrome (PMS), the end date of PMS, and the PMS period, the body temperature measured daily for each individual who has undergone personal authentication is checked to see if it falls into the high or low temperature period, and one or more of the start date of menstruation, the end date of menstruation, the menstrual cycle, the day of ovulation, the start date of premenstrual syndrome (PMS), the end date of PMS, and the PMS period are estimated based on the user's past menstrual cycle, ovulation cycle, etc. Note that each individual may have an irregular menstrual cycle, but even in cases where the menstrual cycle is irregular, it is possible to estimate the start date of menstruation with a certain range of periods based on the user's past menstrual cycle.

[0038] The ovulation date can be estimated based on the body temperature measured daily for each authenticated individual, for example, by referring to the measurement data in Figure 6 and observing the temperature change that occurs when the low temperature phase transitions to the high temperature phase. Furthermore, the high temperature phase (luteal phase) after ovulation varies little from person to person, as with the menstrual cycle, and is constant at about 14 days for everyone. Therefore, the menstruation start date can be estimated by calculating 14 days after the ovulation date. The menstruation end date can be estimated as the day obtained by adding a predetermined number of days to the menstruation start date (menstruation start date + predetermined number of days (3 to 7 days, for example, 5 days)). The menstrual cycle can be estimated, for example, by averaging the number of days between past ovulation dates.

[0039] Premenstrual syndrome (PMS) is a mental or physical symptom that begins 3 to 10 days before the onset of menstruation and disappears with the onset of menstruation. The onset date of PMS can be estimated based on the estimated onset date of menstruation. The onset date of PMS can be estimated to be 3 to 10 days before the onset date of menstruation. The end date of PMS can be estimated, for example, to be the first day of menstruation. The duration of PMS can be estimated as the period from the onset date to the end date of PMS, or the period from the day of ovulation to the day menstruation starts.

[0040] The notification control unit 183 (transmission unit) transmits the woman's menstrual ovulation information estimated by the estimation unit 182, that is, at least one of the estimated information of the menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period, to the external remote control terminal 17 (receiving unit, notification unit), and the remote control terminal 17 receives the estimated information signal, thereby controlling the remote control terminal 17 to notify the estimated information estimated by the estimation unit 182. The notification control unit 183 can control the remote control terminal 17 to notify the estimated information of a future ovulation date regarding the ovulation date estimated by the estimation unit 182, and can also control the remote control terminal 17 to notify the estimated information of a past ovulation date. The notification control unit 183 can notify the estimated information estimated by the estimation unit 182, for example, by controlling the remote control terminal 17 to display the information on a display unit of the remote control terminal 17 or to notify the remote control terminal 17 by voice. The contents displayed on the display unit of the remote control terminal 17 include, for example, a first display example, as shown in FIG. 12, which displays a graph of changes in basal body temperature and the body temperature on a specified day, and a second display example, as shown in FIG. 13, which displays the estimated expected date of menstruation, the expected date of ovulation, and the possibility of pregnancy.

[0041] Next, the flow when a female user uses the toilet device 1 of this embodiment will be described with reference to Figure 7. The toilet device 1 of this embodiment measures the daily body temperature of the female user seated on the toilet seat, and estimates menstrual and ovulation information related to the woman's menstruation and ovulation, i.e., the menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period, and notifies the female user in the toilet room 100 of this information.

[0042] First, in step S1 shown in Fig. 7, when a female user enters the toilet room 100, an entry signal is output from the entry sensor 15, and it is detected that a person has entered the toilet room 100. Here, the female user is identified by the personal authentication function of the identification function unit 181 of the control unit 18, and is identified as a woman registered in the identification function unit 181. For example, the female user can be identified by selecting to identify the user using a selection button that identifies the registered woman.

[0043] In step S2, when a female user sits on the toilet seat 12 of the toilet device 1, the seat sensor 16 outputs a seating signal, and it is detected that a person has sat on the toilet seat 12.

[0044] In step S3, the female user's body temperature is measured by the body temperature sensor 14 provided on the surface of the toilet seat 12. The female user's body temperature is preferably measured every morning. In this embodiment, the female user preferably measures her body temperature every day so that daily basal body temperature data is accumulated to estimate the woman's menstrual and ovulation information (menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, PMS duration) based on the basal body temperature method.

[0045] In step S4, the estimation unit 182 of the control unit 18 estimates the woman's menstrual ovulation information (menstruation start date, menstruation end date, menstrual cycle, ovulation day, premenstrual syndrome (PMS) start date, PMS end date, PMS duration) based on the female user's body temperature measured by the body temperature measurement sensor 14 and with reference to the accumulated basal body temperature data. The estimation of the woman's menstrual ovulation information (menstruation start date, menstruation end date, menstrual cycle, ovulation day, premenstrual syndrome (PMS) start date, PMS end date, PMS duration) is performed based on the basal body temperature method using the user's accumulated body temperature data measured daily.

[0046] In step S5, the estimated menstrual ovulation information of the woman (menstruation start date, menstruation end date, menstrual cycle, ovulation day, premenstrual syndrome (PMS) start date, PMS end date, PMS period) is notified. The notification control unit 183 of the control unit 18 controls the remote control terminal 17 (notification unit) to transmit the estimated menstrual ovulation information of the woman (menstruation start date, menstruation end date, menstrual cycle, ovulation day, premenstrual syndrome (PMS) start date, PMS end date, PMS period) to the remote control terminal 17, and notify the estimated information estimated by the estimation unit 182. The notification by the remote control terminal 17 is performed, for example, by displaying on a display unit of the remote control terminal 17 or by sound from the remote control terminal 17. When the measurement of the female user's body temperature is completed, an alarm may be sounded to notify the completion of the measurement, or when the estimated female menstrual and ovulation information (menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, PMS duration) is notified, an alarm may be sounded in addition to a display or voice. After step S5, the process ends.

[0047] According to this embodiment, the following effects are achieved: The toilet apparatus 1 of this embodiment includes a toilet seat 12, a body temperature sensor 14 that is arranged on the surface of the toilet seat 12 and that measures the body temperature of a person sitting on the toilet seat 12, an estimation unit 182 that estimates menstruation and ovulation information related to a woman's menstruation and ovulation, that is, at least one of the menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period, based on the person's body temperature measured by the body temperature sensor 14, and a notification control unit 183 (transmission unit) that transmits the estimated information estimated by the estimation unit 182 to an external remote control terminal 17 (reception unit).

[0048] Therefore, simply by sitting on the toilet seat 12, the user's body temperature can be measured to estimate at least one of the menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS duration, and this estimated information can be reported, so compared to technology that measures the temperature of a woman's urine to estimate the menstrual cycle, etc., it is possible to quickly, simply, and reliably estimate and report at least one of the menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS duration. This makes it less likely that a user will forget to prepare / change sanitary products, and makes it easier to prepare / change sanitary products.

[0049] In this embodiment, the toilet seat 12 is formed in a ring shape with an opening 121 on the inside, and the detection unit 141 of the body temperature sensor 14 is positioned closer to the opening 121 of the toilet seat 12 with respect to a central imaginary line L that extends along the center of the width of the ring-shaped part of the toilet seat 12 in a plan view. This allows for a closer fit of the detection unit 141 of the body temperature sensor 14 to the thighs of a female user when the toilet seat 12 is used by a female user whose center of gravity is positioned closer to the inside of the toilet seat 12 when sitting on the toilet seat 12, and allows for accurate measurement of the female user's body temperature.

[0050] In this embodiment, the toilet seat 12 is formed in a ring shape with an opening 121 on the inside, and the detection unit 141 of the body temperature measurement sensor 14 is arranged so that, in a plan view, the area S1 of the detection unit 141 arranged in the region on the opening 121 side of the toilet seat 12 is equal to or greater than the area S2 of the detection unit 141 arranged in the region opposite the opening 121 of the toilet seat 12, relative to a central imaginary line L extending along the center of the width of the ring-shaped part of the toilet seat 12. As a result, when used by a woman whose center of gravity when seated on the toilet seat 12 is positioned closer to the inside of the toilet seat 12, the detection unit 141 of the body temperature measurement sensor 14 can be fitted more closely to the thighs of the female user, allowing the body temperature of the female user to be measured accurately.

[0051] In this embodiment, the toilet seat 12 has a sensor placement portion 122 where the detection portion 141 of the body temperature measurement sensor 14 is placed, and the sensor placement portion 122 is formed to be raised higher than the surface of the surrounding area 123 of the sensor placement portion 122 on the toilet seat 12. By placing the body temperature measurement sensor 14 in the sensor placement portion 122 which is raised higher than the surrounding area 123, it is possible to increase the adhesion to the thighs of female users and to measure the body temperature of female users with high accuracy.

[0052] In this embodiment, the detection unit 141 of the body temperature measurement sensor 14 is positioned in a plan view of the toilet seat 12 so as not to overlap the heating wire 145 for the heater housed inside the toilet seat 12. This allows the body temperature measurement sensor 14 to be positioned in a position that is less susceptible to the heat of the heating wire 145, thereby reducing errors in body temperature measurement due to the influence of the heating wire 145 and improving the accuracy of body temperature measurement.

[0053] In this embodiment, the detection unit 141 of the body temperature sensor 14 is disposed inside the toilet seat 12, which is formed from a resin material, and the thickness of the resin material in the portion where the detection unit 141 of the body temperature sensor 14 is disposed is thinner than the thickness of the portion 123 surrounding the detection unit 141. As a result, the thickness of the sensor disposition portion 122 of the toilet seat 12 where the body temperature sensor 14 is disposed is thin, thereby improving the thermal conductivity of the body temperature sensor 14 to the detection unit 141.

[0054] In this embodiment, the toilet seat 12 is formed containing a resin material, and the thermal conductivity of the entire toilet seat 12, or the thermal conductivity of only the resin portion around the detection unit 141 of the body temperature sensor 14, is higher than 0.125 W / mK. By making the thermal conductivity of the entire toilet seat 12, or the thermal conductivity of only the resin portion around the detection unit 141 of the body temperature sensor 14, higher than 0.125 W / mK, the thermal conductivity can be made higher than that of polypropylene (PP), a resin material generally used for toilet seats 12, and heat can be more easily transferred to the detection unit 141 of the body temperature sensor 14.

[0055] In this embodiment, the toilet seat 12 has a first portion 124 around the detection unit 141 of the body temperature measurement sensor 14, and a second portion 125 other than the area around the body temperature measurement sensor 14. The thermal conductivity of the first portion 124 (see FIGS. 1 and 4) may be higher than the thermal conductivity of the second portion 125 (see FIG. 1). In this case, when a female user sits on the toilet seat 12, heat can be more easily transferred to the detection unit 141 of the body temperature measurement sensor 14 around the detection unit 141 of the body temperature measurement sensor 14.

[0056] In this embodiment, an identification function unit 181 is provided for identifying a user. As a result, by identifying a female user using the identification function unit 181, it is possible to individually manage, for each identified female user, at least one piece of information on the start date of menstruation, the end date of menstruation, the menstrual cycle, the day of ovulation, the start date of premenstrual syndrome (PMS), the end date of PMS, and the PMS period. Furthermore, it is possible to individually notify the identified female user of at least one piece of information on the start date of menstruation, the end date of menstruation, the menstrual cycle, the day of ovulation, the start date of premenstrual syndrome (PMS), the end date of PMS, and the PMS period.

[0057] Next, a second embodiment of the present disclosure will be described in detail with reference to the drawings. In the second embodiment, the main difference from the number of detection units 141 of the body temperature measurement sensor 14 of the toilet device 1 of the first embodiment is the number of detection units 142 of the body temperature measurement sensor 14A. In the second embodiment, components similar to those of the first embodiment are given the same reference numerals in the drawings, and their description will be omitted.

[0058] As shown in Figure 8, the body temperature measurement sensor 14A of the toilet device 1A of the second embodiment has a plurality of detection units 142 that are arranged in a line in the front-to-back direction of a person when the person is seated on the toilet seat 12. In this embodiment, the plurality of detection units 142 are arranged inside the toilet seat 12. The plurality of detection units 142 are arranged in a line along the annular part of the toilet seat 12, and when the toilet device 1A is viewed from the side, the plurality of detection units 142 are arranged in a line in the front-to-back direction on each of the left and right sides, with five detection units 142 arranged in a line on each side.

[0059] In this embodiment, for example, a total of ten pairs of detecting units 142 are provided, five on each side, and are arranged in the order of detecting units 142a, 142b, 142c, 142d, and 142e from the front to the rear in the front-to-rear direction on each side of the toilet seat 12. By providing multiple detecting units 142, the likelihood that one of the multiple detecting units 142 of the body temperature measurement sensor 14 will come into close contact with the thigh of the female user increases even if the female user's sitting position on the toilet seat 12 varies slightly, so the detecting units 142 of the body temperature measurement sensor 14 can be more closely fitted to the thigh of the female user, and the body temperature of the female user can be measured with high accuracy.

[0060] There is no limitation on the number of the multiple detectors 142. The multiple detectors 142 may be provided in pairs on the left and right, for example, with two to four or six or more detectors 142 arranged in the front-to-rear direction on each side.

[0061] In this embodiment, all of the multiple detection units 142 of the body temperature sensor 14A are positioned closer to the opening 121 than the imaginary central line L that extends along the center of the width of the annular portion of the toilet seat 12 in a plan view, and are therefore positioned closer to the opening 121 of the toilet seat 12 than the imaginary central line L that extends along the center of the width of the annular portion of the toilet seat 12. This makes it possible to increase the adhesion of the detection units 142 of the body temperature sensor 14A to the thighs of a female user when used by a woman whose center of gravity is positioned closer to the inside of the toilet seat 12 when sitting on the toilet seat 12, and allows the body temperature of the female user to be measured accurately.

[0062] It should be noted that it is not necessary that all of the multiple detection units 142 of the body temperature measurement sensor 14A be positioned closer to the opening 121 of the toilet seat 12 than the central imaginary line L that extends along the center of the width of the annular portion of the toilet seat 12. It is sufficient that at least one detection unit 142 of the multiple detection units 142 of the body temperature measurement sensor 14A is positioned closer to the opening 121 of the toilet seat 12 than the central imaginary line L that extends along the center of the width of the annular portion of the toilet seat 12 in a plan view.

[0063] In a configuration in which the body temperature measuring sensor 14A has multiple detection units 142, similar to the configuration described in the first embodiment, the portion of the toilet seat 12 where the multiple detection units 142 are arranged may be formed as a raised portion, or the thickness of the resin material may be formed as a thin wall.

[0064] In a configuration in which the body temperature measuring sensor 14A includes a plurality of detecting units 142, the control unit 18A can execute, for example, the following first and second control examples.

[0065] As a first control example, in a configuration in which the body temperature measurement sensor 14A includes a plurality of detection units 142, the estimation unit 182 of the control unit 18A uses the highest temperature or the highest body temperature data within a predetermined temperature range among the body temperature data acquired from the plurality of detection units 142 to estimate menstrual and ovulation information related to a woman's menstruation and ovulation. By using the highest temperature or the highest body temperature data within a predetermined temperature range, it is possible to accurately measure and estimate body temperature in daily body temperature measurements. The predetermined temperature range may be set to, for example, 36.0°C to 36.8°C, and any temperature measured outside this range may be treated as an error.

[0066] As a second control example, the control unit 18A includes a seating position determination unit 184 in addition to the configuration of the control unit 18 of the first embodiment, as shown in Fig. 9. When a person sits on the toilet seat 12, the seating position determination unit 184 determines the front-to-rear position of the person sitting on the toilet seat 12 based on temperature data detected by the multiple detection units 142.

[0067] When a person sits on the toilet seat 12 with a plurality of detection units 142 arranged at equal intervals in the front-to-rear direction, the seating position determination unit 184 determines the positional deviation when the person sits shallowly or deeply on the toilet seat 12, selects the detection unit 142 with the most suitable positional relationship, and adopts the measurement value of the selected detection unit 142.

[0068] Specifically, in a state where multiple detectors 142 are arranged at equal intervals in the front-to-rear direction, when a female user W sits deep on the toilet seat 12 as shown in Fig. 10A, of the five detectors 142, four detectors 142a, 142b, 142c, and 142d, arranged from the front to the rear, detect a body temperature within a preset temperature range (e.g., 36.0°C to 36.8°C). Therefore, the seating position determination unit 184 determines that the thigh W1 of the female user W is present in the range X1 between detectors 142a and 142d, and uses the measurement value of detector 142c, which is located a predetermined number forward (the first one forward in Fig. 10A) from detector 142d, which is estimated to be located at the end of the rear side of the thigh W1 of the female user W.

[0069] 10B, when a female user W sits shallowly on the toilet seat 12, three of the five detectors 142, namely, detectors 142a, 142b, and 142c, located from the front to the rear, detect a body temperature within a preset temperature range (for example, 36.0°C to 36.8°C). Therefore, the seating position determination unit 184 determines that the thigh W1 of the female user W is present within the range X2 between detectors 142a and 142c, and uses the measurement value of detector 142b, which is located a predetermined number forward (the first one forward in the case of FIG. 10B) from detector 142c, which is estimated to be located at the end of the rear side of the thigh W1 of the female user W.

[0070] The predetermined number of detectors to be arranged is determined as appropriate depending on the number of detectors and the spacing between adjacent detectors. In this embodiment, the predetermined number of detectors 142c and 142b are detectors arranged, for example, about 3 to 10 cm (preferably 5 cm) forward from the rear end of a woman's thigh. The lower portion 3 to 10 cm forward from the rear end of a woman's thigh is a position where the pair of detectors 141 can stably fit closely to the woman's thigh and stably measure the body temperature of the female user. Note that if the ranges X1 and X2 in which the multiple detectors 142 detect a person's body temperature are narrower than the predetermined range, an error can be determined.

[0071] Based on the determination result of the seating position determination unit 184, the estimation unit 182 employs predetermined detection units 142c, 142b from among the plurality of detection units 142, and estimates one or more of the menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period based on the person's body temperature measured by the predetermined detection units 142c, 142b.

[0072] As described above, in a configuration having a plurality of detection units 142, the seating position determination unit 184 determines the seating position of the female user on the toilet seat 12, and by adopting predetermined detection units 142c, 142b from the plurality of detection units 142 based on the determination result of the seating position determination unit 184 in the lower part of the woman's thigh a predetermined distance (approximately 3 to 10 cm) forward from the rear end of the woman's thigh, detection units 142c, 142d can be stably attached to the woman's thigh, and the body temperature of the female user can be stably measured.

[0073] The body temperature measurement sensor 14A described above has multiple detection units 142 that are arranged in a row in the front-to-back direction of a person when seated on the toilet seat 12. This increases the likelihood that one of the multiple detection units 142 of the body temperature measurement sensor 14 will come into close contact with the thigh of a female user even if the female user's sitting position on the toilet seat 12 varies slightly, thereby improving the adhesion of the detection units 142 of the body temperature measurement sensor 14 to the thigh of the female user and enabling the body temperature of the female user to be measured accurately.

[0074] Next, a third embodiment of the present disclosure will be described in detail with reference to the drawings. The third embodiment differs from the detection unit 141 of the body temperature measurement sensor 14 of the toilet device 1 of the first embodiment mainly in that the detection unit 143 of the body temperature measurement sensor 14B is disposed exposed to the outside on the surface of the toilet seat 12. In the third embodiment, components similar to those in the first embodiment are designated by the same reference numerals in the drawings, and their description will be omitted.

[0075] 11, the body temperature measuring sensor 14B includes a detection unit 143 that is exposed on the surface of the toilet seat 12 and placed above the surface of the toilet seat 12, a wiring unit 143a that runs from the toilet seat 12-facing surface (back surface) of the detection unit 143 to the inside of the toilet seat 12 through a through-hole 12a provided in the surface of the toilet seat 12, and a resin O-ring 12b for preventing water leakage. The detection unit 143 detects the body temperature of a person.

[0076] Although not shown, detection unit 143 is formed, for example, in a circular shape when viewing toilet seat 12 in a plan view. The size of detection unit 143 is formed, in a plan view, to be larger than through-hole 12a provided in the surface of toilet seat 12. O-ring 12b for water blocking is disposed between the surface of detection unit 143 facing the toilet seat 12 and the surrounding area of ​​through-hole 12a on the surface of toilet seat 12.

[0077] This prevents moisture and detergent components from penetrating into the toilet seat 12 through the gap between the detection unit 143 and the surface of the toilet seat 12 during cleaning, even if the detection unit 143 is exposed on the surface of the toilet seat 12.

[0078] Next, a fourth embodiment of the present disclosure will be described. As shown in Figures 14 and 15, the fourth embodiment has a configuration in which an add-on toilet seat 3 is attached to a toilet seat 12C (see Figure 15) after installation. The add-on toilet seat 3 is equipped with an ovulation prediction device 2A. In the fourth embodiment, descriptions of the same configuration as in the first embodiment will be omitted.

[0079] As shown in Figures 14 and 15, the toilet apparatus 1C includes a toilet bowl 11 and a toilet seat 12C. The toilet seat 12C is attached to the top of the toilet bowl 11. The add-on toilet seat 3 is attached to the top of the toilet seat 12C. The add-on toilet seat 3 forms a seating area on which a person sits. The add-on toilet seat 3 is placed on the edge of the opening of the toilet seat 12C and is formed in an annular shape. An ovulation prediction device 2A is built into the top of the interior of the add-on toilet seat 3.

[0080] The ovulation estimation device 2A includes the body temperature measurement sensor 14 of the ovulation estimation device 2 of the first embodiment, and the identification function unit 181, estimation unit 182, and notification control unit 183 (transmission unit) in the control unit 18 (see Figure 2) of the ovulation estimation device 2 of the first embodiment.

[0081] The notification control unit 183 (transmitting unit) transmits the woman's menstrual ovulation information estimated by the estimation unit 182, that is, at least one of the estimated information of the menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period, to a remote control terminal 17 (receiving unit, notification unit) outside the ovulation estimation device 2A.

[0082] The body temperature measurement sensor 14 of the first embodiment provided in the ovulation estimation device 2A, and the identification function unit 181, estimation unit 182 and notification control unit 183 (transmission unit) in the control unit 18 (see Figure 2) of the ovulation estimation device 2 of the first embodiment provided in the ovulation estimation device 2A have the same configuration and functions as the first embodiment.

[0083] The fourth embodiment can achieve the same effects as the first embodiment. Furthermore, according to the fourth embodiment, the ovulation prediction device 2A can be easily attached to the toilet seat 12C by attaching the add-on toilet seat 4 equipped with the ovulation prediction device 2A to the toilet seat 12B without replacing the toilet apparatus 1 or the toilet seat 12C.

[0084] Next, a fifth embodiment of the present disclosure will be described. In the fifth embodiment, as shown in Fig. 16, the ovulation prediction device 2B is made into a single unit, so that the unitized ovulation prediction device 2B can be attached directly to the toilet seat 12 of the toilet device 1 afterwards. In the fifth embodiment, the description of the same configuration as in the first embodiment will be omitted.

[0085] The ovulation prediction device 2B is formed in a box shape or a thick sheet shape, and by unitizing it, it is configured as a separate unit from the toilet seat 12D and can be attached to the toilet seat 12D afterwards. The toilet seat 12D forms a seating area on which a person sits. The ovulation prediction device 2B can be attached to the part of the toilet seat 12D on which a person sits afterwards, for example, with adhesive tape, hook-and-loop fasteners, or the like.

[0086] As in the fourth embodiment, the ovulation estimation device 2B includes the body temperature measurement sensor 14 of the ovulation estimation device 2 of the first embodiment, and the identification function unit 181, estimation unit 182, and notification control unit 183 (transmission unit) in the control unit 18 (see Figure 2) of the ovulation estimation device 2 of the first embodiment.

[0087] As in the fourth embodiment, the notification control unit 183 (transmitting unit) transmits the woman's menstrual ovulation information estimated by the estimation unit 182, that is, at least one of the estimated information of the menstruation start date, menstruation end date, menstrual cycle, ovulation date, premenstrual syndrome (PMS) start date, PMS end date, and PMS period, to a remote control terminal 17 (receiving unit, notification unit) outside the ovulation estimation device 2B.

[0088] The body temperature measurement sensor 14 of the first embodiment provided in the ovulation estimation device 2B, and the identification function unit 181, estimation unit 182 and notification control unit 183 (transmission unit) in the control unit 18 (see Figure 2) of the ovulation estimation device 2 of the first embodiment provided in the ovulation estimation device 2B have the same configuration and function as the first embodiment, as in the fourth embodiment.

[0089] The fifth embodiment can achieve the same effects as the first embodiment. Furthermore, according to the fifth embodiment, the ovulation prediction device 2B is formed in a box shape or a thick sheet shape, and is formed compactly, so that it is easy to carry, attach and detach, and handle.

[0090] Although the preferred embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments and can be modified as appropriate.

[0091] For example, in the above embodiment, the notification unit is configured by the remote control terminal 17, but is not limited to this. The notification unit may be installed in the toilet room 100, or may be an information terminal (such as a smartphone) that is not installed in the toilet room 100.

[0092] If it is not possible to make an estimate based on a person's body temperature (if the body temperature data is too irregular or incomplete due to measurement errors, etc., and the basal body temperature method cannot be applied), the user can input the actual start and end dates of menstruation into the toilet operation unit (remote control terminal) or application software in a separate information terminal (smartphone, etc.), and the system can estimate and notify the date based on the data obtained from that (corresponding to the so-called "Ogino method"). Alternatively, an image sensor or the like can be installed on the toilet seat and the amount of menstrual blood can be measured to estimate the start date of menstruation, and the end date of menstruation, etc. can be estimated and notified.
