BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a bathroom heating/drying system according to the present invention will be described in detail below with reference to the drawings. In addition, the embodiment described below is an illustration for demonstrating this invention, and does not limit this invention only to these embodiments. Therefore, the present invention can be embodied in various forms without departing from the gist thereof.

[First embodiment]
FIG. 1 shows a block diagram of a schematic configuration of a bathroom heating/drying system 1 according to this embodiment. The bathroom heating and drying system 1 used in the bathroom X includes a bathroom temperature sensor 10 (an example of a bathroom temperature detection unit), an outside temperature sensor 12 (an example of an outdoor temperature detection unit), a controller (remote control) 14 (inside the bathroom temperature detection unit), heat source device 16 (heating unit), flow sensor 18, temperature-related information storage unit 20, bathing time estimation unit 22, bathroom temperature estimation unit 24, calculation unit 26, determination unit 28, notification It has a unit 30 and a control unit 32 that controls them. The bathroom heating and drying system 1 uses hot water heated by the heat source device 16 to fill the bathtub in the bathroom X and use a hot water shower (hereinafter referred to as hot water supply by hot water filling and hot water by using the hot water shower It is a system that can heat and dry the bathroom X by sending hot air to the bathroom X.

The bathroom temperature sensor 10 has a function of detecting (measuring) the space temperature in the bathroom X (an example of the temperature in the bathroom; hereinafter simply referred to as “bathroom space temperature”) and outputting an electrical signal corresponding to the temperature. . In this embodiment, the bathroom temperature sensor 10 is installed in the bathroom X at a height of 1.2 m to 1.6 m from the floor, which is the height of the upper body of a person. The bathroom temperature sensor 10 detects the temperature of the bathroom space every hour (detects a plurality of times) in response to an instruction from the control unit 32, and sends an electric signal corresponding to the temperature to the temperature-related information storage unit 20. output to. The temperature detection interval by the bathroom interior temperature sensor 10 may not be every hour, and may be detected at arbitrary intervals. Also, the detection intervals do not necessarily have to be equal, and the detection intervals may be different. For example, the detection interval during the day when the bathroom X is often not used may be lengthened, and the detection interval during the night when the bathroom X is often used may be shortened. The bathroom space temperature is detected by the bathroom temperature sensor 10 continuously 24 hours a day, 365 days a year. As a result, it is possible to detect the bathroom space temperature according to the season and time and store it in the temperature-related information storage unit 20 . The temperature of the bathroom space when the hot water supply is not used can be approximated to the temperature of the dressing room.

The outdoor air temperature sensor 12 has a function of detecting (measuring) the outdoor air temperature (hereinafter also simply referred to as "outdoor air temperature") in the vicinity of the bathroom X and outputting an electrical signal corresponding to the temperature. In this embodiment, the outside air temperature sensor 12 is installed outside the heat source equipment 16 installed outdoors and is not affected by the heat generated by the heat source equipment 16 . The outside air temperature sensor 12 detects the outside air temperature at the same timing as the bathroom temperature sensor 10 detects the temperature in response to an instruction from the control unit 32, and outputs an electric signal corresponding to the temperature to the temperature-related information storage unit. Output to 20. The outside temperature sensor 12 also continuously detects the outside temperature 24 hours a day, 365 days a year.

The controller 14 is installed inside and/or outside the bathroom X, and sets the temperature of the hot water supplied to the bathroom X (an example of the temperature in the bathroom) and the heating and drying functions in the bathroom X. Electric signals relating to hot water supply temperature, heating, and drying settings set by the controller 14 are input to the control unit 32, and the control unit 32 causes the heat source device 16 to execute the set operation.

The heat source device 16 has a function of heating hot water to a required temperature when supplying hot water at a temperature set by the controller 14 or heating and drying the bathroom X according to the setting of the controller 14 . Further, the flow rate sensor 18 detects the flow rate of hot water for hot water supply heated by the heat source device 16, and determines whether the hot water supply is in use or not. A determination result is output toward the temperature-related information storage unit 20 . The use state and non-use state of hot water supply may be determined by any other method.

The temperature-related information storage unit 20 stores the bathroom space temperature detected by the bathroom temperature sensor 10, the outside temperature detected by the outside temperature sensor 12, the date and time when these temperatures were detected, and the use or non-use of hot water supply detected by the flow sensor 18. The determination result and the hot water supply temperature set by the controller 14 when using hot water supply are stored in association with each other (see FIG. 2). The date and time of detection may be obtained by any method, such as obtaining from the temperature sensor 10 in the bathroom or the clock built in the control unit 32, or obtaining by receiving radio waves of time information.

The bathing time estimating unit 22 reads the hot water supply usage frequency for each detection time stored in the temperature-related information storage unit 20, and estimates the bathing time on a predetermined day (hereinafter referred to as "estimated day") for estimation ( The estimated bathing time is hereinafter referred to as “estimated bathing time”). That is, the time zone (at the time of detection) in which hot water supply is frequently used is estimated as the estimated bathing time. FIG. 3 shows the relationship between the hot water supply usage time stored in the temperature-related information storage unit 20 and its frequency. The estimated bathing time is the time to use the hot water supply in the bathroom X, the time to take a bath after filling the bathtub with hot water, and the time to take a bath using the shower if it is a hot water shower. The estimated bathing time may be estimated to be the time zone in which hot water supply is used most frequently, or may be estimated to be the earliest time zone among the time zones in which the frequency of hot water supply is greater than or equal to a predetermined frequency. In addition, since bathing times may differ depending on the season, the estimation of the time zone with high hot water usage frequency on the estimated day is divided into winter, middle season, summer, etc., and the frequency of hot water usage in the season is estimated. A high time zone may be extracted, and the bathing time for the estimated day may be estimated based on this. Alternatively, instead of limiting the estimated date to a specific day, a time period in which the hot water supply frequency is high in the season (winter, middle season, summer) including the estimated date may be extracted. Hereinafter, the term “estimated date” includes the meaning of “the season in which the estimated date is included”. The estimated bathing time on the estimated date is output to the bathroom temperature estimating section 24 .

When the estimated bathing time for the estimated day estimated by the bathing time estimating unit 22 is input, the bathroom temperature estimating unit 24 calculates the bathroom space temperature when hot water is being supplied and the bathroom space temperature when hot water is not being used, which are stored in the temperature-related information storage unit 20 . of bathroom space temperature and read. If there are a plurality of bathroom space temperatures at the time, bathroom interior temperature estimating unit 24 calculates the average value of these, and determines the bathroom space temperature when hot water supply is in use and the bathroom space temperature when hot water supply is not in use. presume. Hereinafter, the estimated bathroom space temperature when hot water supply is used is referred to as "estimated bathroom temperature when hot water supply is used", and the estimated bathroom space temperature when hot water supply is not used is referred to as "estimated bathroom space temperature when hot water supply is not used". . In addition to the average value, the bathroom temperature estimating unit 24 may calculate arbitrary statistics such as the median value and the mode value as the estimated bathroom temperature when hot water supply is in use and the estimated bathroom temperature when hot water supply is not in use. good.

As shown in FIG. 4, the temperature of the bathroom space when hot water is supplied is almost constant regardless of the season (outside temperature), but the temperature of the bathroom space when hot water is not used changes depending on the season (outside temperature). That is, if the outside air temperature is high, the bathroom space temperature is high when hot water supply is not used, and if the outside temperature is low, the bathroom space temperature is low when hot water supply is not used. Therefore, when estimating the bathroom space temperature when hot water supply is not used, the bathroom space temperature when hot water supply is not used is estimated based on the outside air temperature (an example of a predetermined outside temperature condition) at the estimated bathing time on the estimated day. . The calculated estimated temperature in the bathroom when hot water supply is used and the estimated temperature in the bathroom when hot water supply is not used are output to the calculation unit 26 . In this embodiment, the temperature of the dressing room is estimated based on the bathroom space temperature when hot water supply is not used, and the temperature of bathroom X is estimated based on the bathroom space temperature when hot water supply is used.

The calculation unit 26 reads the estimated temperature in the bathroom when hot water supply is in use and the estimated temperature in the bathroom when hot water supply is not in use estimated by the bathroom temperature estimating unit 24, and calculates the estimated temperature in the bathroom when hot water supply is in use and the estimated temperature in the bathroom when hot water supply is not in use. Calculate the difference (temperature difference). Then, the calculated difference is output to the determination section 28 .

Heat shock is caused by the difference in temperature between the dressing room and the bathroom X, and between the temperature of the bathroom X and the hot water supply of the bathtub or hot water shower, especially in winter. It is caused by excessive strain on the body due to fluctuations in the body. Therefore, for example, when the temperature in the dressing room is high and the temperature in the bathroom X is low, there is a risk of heat shock due to sudden fluctuations in blood pressure when entering the bathroom X. Also, when the temperature in the bathroom X is low, there is a risk of heat shock due to sudden changes in blood pressure when soaking in the bathtub or taking a hot shower. The risk of heat shock increases when there is a large difference in temperature between a low-temperature location and a high-temperature location.

The determination unit 28 determines whether or not the difference between the estimated bathroom temperature when hot water supply is in use and the estimated bathroom temperature when hot water supply is not in use calculated by the calculation unit 26 exceeds a predetermined difference (for example, 20° C.). do. If the difference between the estimated bathroom temperature with hot water supply and the estimated bathroom temperature without hot water supply exceeds a predetermined difference, the determination unit 28 determines that there is a risk of heat shock when taking a bath during the estimated bathing time. If it does not exceed a predetermined difference, it is determined that there is no risk of heat shock.

The estimation of the bathing time on the estimated day by the bathing time estimating unit 22 and the determination of the risk of heat shock during the estimated bathing time by the bathroom temperature estimating unit 24, the calculating unit 26, and the determining unit 28 are carried out during the estimated day. It is performed once at a preset time in the system 1 . For example, it can be set to an arbitrary time such as 7:00 am, 12:00 pm, 5:00 pm, etc. on the estimated day, but it is possible to set it to a few hours before the earliest bathing time (the earliest time to use hot water for bathing) It is preferable to set the time. That is, before hot water supply is used, the risk of heat shock occurring during the estimated bathing time is determined. The time can be set using the controller 14 .

When the determination unit 28 determines that there is a risk of heat shock when taking a bath at the estimated bathing time on the estimated date, the control unit 32 instructs the notification unit 30 to The pre-registered contact information is informed of the estimated bathing time that is the basis of the judgment and the risk of heat shock if bathing during the estimated bathing time. For example, a message is sent to the pre-registered phone number or e-mail address of the mobile information terminal 50, or a push notification is sent. Examples of pre-registered contact information include the user (resident) who uses the bathroom X determined by the determination unit 28, and if the user is elderly, relatives of the user who live in a remote location. is applicable.

In this way, when the bathroom heating/drying system 1 determines that there is a risk of heat shock occurring when taking a bath during the estimated bathing time, the notification unit 30 is set to the portable information terminal 50 in advance before using the hot water supply. By notifying the registered contact that there is a risk, the person who received the notification before the actual bathing time (which does not necessarily match the estimated bathing time) or the user of the bathroom X Appropriate measures can be taken to avoid the risk of heat shock, such as heating the inside of the bathroom X to warm it.

In place of or in addition to the notification by the notification unit 30, the control unit 32 operates the heat source device 16 to change the estimated temperature in the bathroom when hot water supply is in use and the estimated temperature in the bathroom when hot water supply is not in use at the estimated bathing time. The inside of the bathroom X is heated from before the estimated bathing time (for example, 30 minutes to 1 hour) so that the difference is determined as no risk of heat shock. Specifically, by heating the inside of the bathroom X, the temperature in the bathroom space becomes higher than the estimated temperature in the bathroom when the hot water supply is not used during the estimated bathing time, and the temperature in the bathroom when the estimated hot water supply is used and the temperature in the bathroom space becomes higher. The difference satisfies the condition (below a predetermined difference) for the determination unit 28 to determine that there is no risk of heat shock. During heating by the heat source device 16, temperature detection by the bathroom temperature sensor 10 and the outside air temperature sensor 12 is not performed.

In this way, if the bathroom space temperature satisfies the condition for determining that there is no risk of heat shock occurring during the estimated bathing time, the difference between the bathroom space temperature and the temperature of the hot water supply is small, so it is possible to soak in the bathtub in bathroom X. Even if you take a hot shower, the risk of heat shock will be reduced.

Next, the processing flow of the bathroom heating/drying system 1 will be described with reference to FIG.

When the detection time comes (Yes in step S1), the bathroom temperature sensor 10 and the outside air temperature sensor 12 detect the temperature, and the detected temperature is stored in the temperature-related information storage unit 20 (step S2). At this time, the temperature-related information storage unit 20 stores the date and time when these temperatures are detected, the determination result of hot water supply use or non-use detected by the flow sensor 18, and the hot water supply when using hot water supply set by the controller 14 when hot water supply is used. Store the temperature together.

When the time set by the controller 14 is reached (Yes in step S3), the bathing time estimating unit 22 reads the frequency of use or non-use of hot water supply for each detection time stored in the temperature-related information storage unit 20, and estimates the bathing time. (step S4). Then, the bathroom temperature estimating unit 24 calculates the bathroom space temperature when hot water supply is in use and the bathroom space temperature when hot water supply is not in use, which are stored in the temperature-related information storage unit 20 at the estimated bathing time estimated by the bathing time estimating unit 22. is read to estimate the bathroom temperature when hot water supply is in use and the bathroom temperature when hot water supply is not in use (step S5).

The calculation unit 26 reads the estimated temperature in the bathroom when hot water supply is in use and the estimated temperature in the bathroom when hot water supply is not in use estimated by the bathroom temperature estimating unit 24, and calculates the estimated temperature in the bathroom when hot water supply is in use and the estimated temperature in the bathroom when hot water supply is not in use. (temperature difference) is calculated (step S6). Then, if the determination unit 28 determines that there is a risk of heat shock based on the difference calculation result (Yes in step S7), the control unit 32 causes the notification unit 30 to notify the risk or operates the heat source device 16. Then, the inside of the bathroom X is heated so as to satisfy the condition for determining that there is no risk of heat shock during the estimated bathing time (step S8).

In this way, when the bathroom heating/drying system 1 determines that there is a risk of heat shock occurring when taking a bath during the estimated bathing time, the heat source device 16 sets the bathroom space temperature during the estimated bathing time before using the hot water supply. becomes higher than the estimated bathroom temperature when hot water supply is not used, and the difference between the estimated bathroom temperature when hot water supply is used and the bathroom space temperature reaches a temperature at which the determination unit 28 determines that there is no risk of heat shock. By doing so, it is possible to take a bath while the inside of the bathroom X is warmed, so that the risk of heat shock can be avoided. In particular, the estimated temperature in the bathroom when hot water supply is not used is estimated based on the outside air temperature at the estimated bathing time on the estimated day, so the risk of heat shock can be determined with high accuracy.

In this way, by using the bathroom heating/drying system 1, the risk of heat shock is predicted before hot water supply is used in bathroom X (before the estimated bathing time), and if there is a risk, measures are taken to avoid the risk. It can be carried out.

[Second embodiment]
In the bathroom heating/drying system 1 of the first embodiment, the temperature of the bathroom space when the hot water supply is not used during the estimated bathing time is input to the bathroom temperature estimating section 24 . As described above, the temperature-related information storage unit 20 stores the bathroom space temperature detected by the bathroom temperature sensor 10 and the outside temperature detected by the outside temperature sensor 12 in association with each other. The bathroom space temperature when not in use is the temperature corresponding to the outside air temperature during the estimated bathing time. In the bathroom heating and drying system 1 according to the present embodiment, the expected temperature ( An example of a predetermined outside temperature condition) is input as the outside temperature to the bathroom temperature estimating unit 24, and the temperature inside the bathroom when the hot water supply is not used is estimated using the bathroom space temperature when the hot water supply is not used corresponding to the outside temperature. do.

The bathroom heating/drying system 1 according to the present embodiment, as shown in FIG. 6, includes a receiving section 34 that receives information (data) on expected temperature from the Meteorological Agency. Other configurations are the same as the bathroom heating/drying system 1 of the first embodiment. When the time set for the above-described risk determination comes, the estimated bathing time estimated by the bathing time estimating unit 22 is input to the receiving unit 34, and the predicted temperature at the estimated bathing time issued by the Meteorological Agency etc. to receive via The received predicted air temperature is output to the bathroom temperature estimating unit 24 . A bathroom temperature estimating unit 24 reads, from the temperature-related information storage unit 20, the temperature in the bathroom when hot water supply is not in use, which corresponds to the same temperature as the input predicted temperature among the plurality of outside temperatures detected by the outside temperature sensor 12. - 特許庁. Other determination procedures are the same as those in the first embodiment, so detailed descriptions are omitted.

In this way, among the outside temperatures detected by the outside temperature sensor 12, heat shock is generated using the temperature inside the bathroom when hot water supply is not in use, which corresponds to the outside temperature corresponding to the expected temperature for the estimated bathing time issued by the Meteorological Agency, etc. Risk determination can be performed with higher accuracy by performing the risk determination.

[Other embodiments]
(1) In each of the above embodiments, the temperature in the bathroom when hot water supply is not used is estimated based on the outside temperature at the estimated bathing time on the estimated day. An example of the condition) may be used to estimate the temperature in the bathroom when the hot water supply is not in use. As shown in Fig. 4, the temperature of the bathroom space when hot water is being supplied is almost constant regardless of the outside air temperature, but the temperature of the bathroom space when hot water is not being used has a positive correlation with the outside air temperature. If the lowest temperature among the outdoor temperatures on the estimated day is used as the estimated bathroom temperature when hot water supply is not used, the difference between the estimated bathroom temperature when hot water supply is on and the estimated bathroom temperature when hot water supply is not used becomes the largest. Therefore, by determining the risk of heat shock occurrence under the most severe conditions, the risk of heat shock occurrence can be more reliably avoided.

(2) In the above embodiment, the risk of heat shock occurrence is determined using the space temperature in the bathroom X as the temperature in the bathroom when hot water is being supplied at the estimated bathing time on the estimated day. The hot water supply temperature when hot water supply is used (hot water filling temperature, hot water shower temperature, an example of the temperature in the bathroom) stored in . Normally, the hot water supply temperature is higher than the bathroom space temperature when hot water supply is used. Therefore, the predetermined difference (temperature difference) between the estimated temperature in the bathroom when hot water supply is used and the estimated temperature in the bathroom when hot water is not used for determining the risk of heat shock by the determination unit 28 is the difference (temperature difference) when the bathroom space temperature is used ( For example, it is preferable to make the difference when using the hot water supply temperature larger (for example, 25° C.) than for example, 20° C.). In fact, heat shock is more likely to occur when soaking in a bathtub or taking a hot shower in bathroom X than when entering bathroom X from a dressing room. Therefore, the risk of heat shock occurrence can be more reliably avoided by determining the risk of heat shock occurrence under conditions where heat shock is likely to occur.

(3) If the number of bathroom space temperatures and outdoor temperatures stored in the temperature-related information storage unit 20 is small, the appropriate bathroom space temperature for the outdoor temperature when hot water is being supplied and the bathroom space temperature when hot water is not being used are extracted. is difficult. In such a case, for example, the temperature-related information storage unit 20 stores in advance the representative values of the bathroom space temperature when hot water supply is in use and the bathroom space temperature when hot water supply is not in use for each season or every hour of the month. By referring to , the risk of heat shock occurrence can be determined even when the number of bathroom space temperatures and outside air temperatures is small.

The configurations of the above embodiments can be combined as much as possible.
