  In addition, as in Patent Document 1, for example, a toilet room temperature control device having a power saving mode in which one day is divided into a plurality of time zones and the switching of the operation and stop of the temperature controller is automatically changed for each time zone. Are known.

  In the above power saving mode, if the toilet room has not been used in the same time period of the predetermined number of days in the past or if the number of times of use has been low, it is determined that power saving is necessary and the operation of the temperature controller in the corresponding control target time period is stopped. In addition, when the toilet room is used or when the number of times of use is large, it is determined that power saving is unnecessary, and the temperature controller in the corresponding control target time zone is operated.

  By the way, the toilet user's stay time in one toilet room varies depending on the user and the size of the urine, etc., but here, for example, a part of the human body is exposed to a cold toilet room. Staying in a toilet room when the temperature in the toilet room is not at a comfortable temperature, such as feeling very cold when staying for a long time or feeling very hot when staying in a narrow and hot toilet room for a long time As the time increases, the user tends to feel uncomfortable.

However, in the power saving mode shown in Patent Document 1, since the output during operation of the temperature controller is not controlled according to the staying time in the toilet room, the output during operation of the temperature controller is set to a low output. If the user who has stayed for a long time feels uncomfortable, and the output during operation of the temperature controller is set to a high output, the discomfort is hardly felt but the power consumption increases.

  Hereinafter, embodiments of the present invention will be described in order.

(Embodiment 1)
This embodiment is an embodiment corresponding to claim 1.

  As shown in FIG. 1 and FIG. 2, the toilet room temperature control device of the present embodiment is a temperature controller 2 for adjusting the temperature in the toilet room 1, and whether the user has entered the toilet room 1. An entrance detection sensor 3 for detecting whether or not, and a control device 10 for controlling the temperature controller 2 based on the detection result of the entrance detection sensor 3, and a toilet bowl 11 is installed in the toilet room 1. .

  The temperature controller 2 includes a cooling device such as a cooling-only air conditioner, a heating device such as a far infrared heater and a panel heater (code heater, oil heater, etc.), or a cooling and heating device such as an air conditioner having a cooling function and a heating function. The panel heater is attached to the wall of the toilet room on both sides of the toilet bowl or is incorporated into the wall.

  The entrance detection sensor 3 includes, for example, a toilet 11 installed in the toilet room 1, a wash counter, a human body detection sensor such as a pyroelectric sensor or an infrared sensor incorporated in a wall or the like. Note that a plurality of entrance detection sensors 3 may be provided to improve detection accuracy.

  The control device 10 includes a control unit 4, a storage unit 5, and a date / time detection unit 6. The control unit 4 includes a storage unit 7, an extraction unit 8, and an output determination unit 9. These units are used to execute an automatic operation mode described below, and the temperature controller 2 is controlled automatically. In the following description, the extraction unit 8 and the output determination unit 9 are described as the extraction unit 8a and the output determination unit 9a in order to distinguish them from those of other embodiments.

  In the automatic operation mode, one day, that is, 24 hours is divided into a plurality of time zones, and the temperature controller 2 is controlled automatically while changing the operation output for each time zone. In this embodiment, as shown in FIG. 3, one day is divided into four time zones from 0 to 6 o'clock, 6 o'clock to 12 o'clock, 12 o'clock to 18 o'clock, and 18 o'clock to 24 o'clock. The operation output of the temperature controller 2 is automatically changed every 6 hours based on the time detected in. Hereinafter, a day that is a target of control in the automatic operation mode is referred to as a control target day, and a time zone that is a target of control is referred to as a control target time zone.

  In the automatic operation mode, the output of the temperature controller 2 is automatically changed for each time zone based on the data of the stay time of the user once in the toilet room 1 detected by the stay time detection means in the past.

  The staying time detecting means detects the staying time of the user in the toilet room 1 once by using the entrance detection sensor 3. Specifically, the control unit 4 measures the time when the user's entry into the toilet room 1 is continuously detected by the entry detection sensor 3, thereby detecting the user's stay time in the toilet room 1. Yes. That is, the staying time detecting means is composed of the entrance detecting sensor 3 and the control unit 4.

  The storage unit 7 causes the storage unit 5 to store the stay time of the toilet room 1 each time detected by the stay time detection unit in each time zone. Thereby, the stay time of the toilet room 1 each time in each time zone in the past from the control target date is stored.

  Based on the data stored in the storage unit 5, the extracting means 8 a has one or more longest stay times per room entry in the same time zone of the past plural days of the control target date as shown in FIG. 3. It is determined which of the plurality of stay time sections divided by the threshold value of the time belongs to which stay time section, and the stay time section is extracted as prediction information.

  In this embodiment, it is provided with stay time sections AC divided by thresholds of 0 minutes and 3 minutes, and the extraction means 8a is the longest of the stay times for each room entry in the same time zone of the past multiple days of the control target day. It is determined to which of the stay time sections A to C the stay time section belongs, and the stay time section is extracted as prediction information.

  More specifically, the extraction means 8a first determines that the time period when the stay time exceeds 3 minutes, which is the upper threshold, among the stay times for each room in each time slot stored in the storage unit 5. Is classified as stay time section A, and if there is no stay time exceeding 3 minutes and less than 3 minutes and there is a stay time exceeding 0 minutes which is the lower threshold, the time zone is classified as stay time section B If there is no stay time exceeding 0 minutes (that is, the toilet room 1 is not used), the time zone is classified into the stay time category C.

  For example, in the example of FIG. 3, since the toilet room 1 was not used in the time zone from 0 to 6:00 on the first day (3 days before the control target date), the time zone is classified into the stay time category C, and 6 Since there was a stay time exceeding 3 minutes which is the upper threshold in the time zone of -12 o'clock, the time zone is classified into stay time section A, and in the time zone of 12-18 o'clock and the time zone of 18 o'clock to 24 o'clock Since there was no stay time exceeding 3 minutes and there was a stay time exceeding 0 minutes, which is the lower threshold, the time zone is classified into stay time section B, and similarly, the second day (the day before the control target day) And each time zone of the 3rd day (the day before the control target day) is also classified into any of the stay time sections A to C.

  Next, the extraction unit 8a extracts, as prediction information, the stay time section having the longest stay time among the stay time sections to which the corresponding time period of the last three days to which the control target day belongs belongs for each control target time period. To do. That is, the extraction means 8a of the present embodiment determines for which time zone the time zone belongs for each time zone of the past plural days corresponding to the control target time zone, and the longest of these stay time zones. The longest stay time segment is extracted from the stay times for each room entry in the same time zone in the past multiple days.

  For example, in the example of FIG. 3, the longest stay time section C among the stay time sections to which the corresponding time periods corresponding to the last three days corresponding to the control target time period from 0 to 6 o'clock belong is extracted as the prediction information. The longest stay time section A is extracted as prediction information among the stay time sections to which the corresponding time period corresponding to the last three days corresponding to the control time period at -12 o'clock belongs, and the control time period at 12-18 pm is extracted. The longest stay time section B is extracted as prediction information among the stay time sections to which the corresponding time period corresponding to the latest three past days belongs, and the corresponding last three days corresponding to the control target time period from 18:00 to 24:00 The longest stay time section A among the stay time sections to which the time zone belongs is extracted as the prediction information.

  The output determination unit 9a is configured to output the output of the temperature controller 2 in each control target time zone in the automatic operation mode based on the stay time segment (that is, the prediction information) corresponding to the control target time zone extracted by the extraction unit 8a. The longer the stay time, the higher the output.

  Specifically, the temperature controller 2 in the automatic operation mode can change the output in stages, and in this embodiment, the temperature controller 2 can be changed in three stages of high output, low output, and operation stop. .

  Then, when the stay time section corresponding to the control target time zone extracted by the extraction means 8a is “A”, the output determining unit 9a sets the output of the temperature controller 2 in the control target time zone to a high output. When the extracted stay time section is “B”, the output of the temperature controller 2 in the control target time zone is set to a low output, and when the extracted stay time section is “C”. The operation of the temperature controller 2 in the control target time zone is stopped.

  Thus, in the automatic operation mode, the control unit 4 controls the operation of the temperature controller 2 based on the output set by the output determination means 9a for the output of each control time zone on the control target date.

  For example, in the example of FIG. 3, in the control target time zone from 0 to 6:00 on the control target date, there is no time zone (stay time) belonging to the stay time category A and the stay time category B in the same time zone of the past three days. Then, the operation of the temperature controller 2 is stopped. Further, in the control target time zone from 6 o'clock to 12 o'clock, there is a time zone that belongs to the cumulative stay time section A in the same time zone for the past three days, so that the temperature controller 2 has a maximum output in the automatic operation mode. Operate with output. Further, in the control target time zone from 12:00 to 18:00, there is no time zone belonging to the stay time zone A and there is a time zone belonging to the stay time zone B in the same time zone for the past three days. The vehicle is operated at a low output that is lower than the high output. Further, in the control target time zone from 18:00 to 24:00, since there is a time zone belonging to the staying time section A in the same time zone for the past three days, the temperature controller 2 is operated at a high output.

  In the toilet room temperature control apparatus according to the present embodiment described above, the stay time segment in which the output of the temperature controller 2 in each control target time zone in the automatic operation mode is extracted by the extraction means 8a, that is, the control target date. On the basis of the stay time section to which the longest of the stay times for each room entry in the same time zone of the past multiple days belongs, the longer the stay time section, the higher the output is determined. For this reason, in the control target time zone where the staying time is expected to be short or unused, the output of the temperature controller 2 is reduced or the operation of the temperature controller 2 is stopped to realize energy saving. it can. In addition, in the control target time zone that is expected to be used by the user who has stayed for a long time, the temperature controller 2 is set to a high output so that the temperature of the toilet room 1 can be surely and quickly set to the optimum set temperature for the user. It is possible to optimize the temperature environment of the toilet room 1 with the user having a long stay time as the top priority.

(Embodiment 2)
This embodiment is an embodiment corresponding to claim 2. In the following description of the present embodiment, the same components as those in the first embodiment are given the same numbers, and redundant descriptions are omitted. In addition, the extraction unit 8 and the output determination unit 9 of the present embodiment are referred to as an extraction unit 8b and an output determination unit 9b, respectively.

  As shown in FIG. 4, the extraction means 8 b of the present embodiment is based on the data stored in the storage unit 5, and is the longest of the accumulated staying times of the toilet room 1 for the same time period on the past plural days of the control target date. It is determined which of the plurality of accumulated stay time sections divided by a threshold of one or more time belongs to which accumulated stay time section, and the accumulated stay time section is extracted as prediction information.

  In this embodiment, it is provided with accumulated stay time sections A to C divided by thresholds of 0 minutes and 10 minutes, and the extraction means 8b is a cumulative stay of the toilet room 1 for the same time zone in the past multiple days of the target date. It is determined which of the accumulated stay time sections A to C the longest time belongs to, and the accumulated stay time section is extracted as prediction information.

  Specifically, the extraction unit 8b first adds the detected stay times for each time period to calculate the accumulated stay time in each time period, and calculates the accumulated stay time as the upper threshold value of 10 minutes. If it exceeds, the time zone is classified into the cumulative stay time category A. If the cumulative stay time is less than 10 minutes and exceeds the lower threshold value of 0 minutes, the time zone is classified as the cumulative stay time category B. When the accumulated stay time is 0 minute (that is, the toilet room 1 is not used in that time zone), the time zone is classified into the accumulated stay time category C.

  For example, in the example of FIG. 4, on the first day (3 days before the control target day), the toilet room 1 was not used in the time zone of 0-6 o'clock, so the time zone was classified into the cumulative stay time category C, In the 6-12 o'clock time zone, the accumulated stay time exceeded the upper threshold of 10 minutes, so the time zone was classified into the accumulated stay time section A, and the 12-18 hour time zone and the 18 o'clock to 24 hour time In the zone, the accumulated stay time did not exceed 10 minutes and the lower threshold value of 0 minutes was exceeded, so each time zone was classified into the accumulated stay time category B. Similarly, the second day (the day before the control target day) ) And the third day (the day before the control target day) are also classified into any of the accumulated stay time categories A to C.

  Next, the extraction unit 8b selects, for each control target time zone, the cumulative stay time segment that has the longest cumulative stay time among the cumulative stay time segments to which the corresponding time zones of the most recent three days belong. Extract as forecast information. That is, the extraction means 8b of the present embodiment determines for which cumulative time period the time zone belongs for each time zone of the past multiple days corresponding to the control target time zone, and By extracting the longest one of them, the accumulated stay time section to which the longest one of the accumulated stay times in the same time zone in the past plural days belongs is extracted.

  For example, in the example of FIG. 4, the longest accumulated stay time section C is extracted as the prediction information among the accumulated stay time sections to which the corresponding time periods corresponding to the last three days corresponding to the control target time period from 0 to 6 o'clock belong. , The longest accumulated stay time section A among the accumulated stay time sections to which the corresponding time period corresponding to the last three days corresponding to the control time period from 6 to 12 o'clock belongs is extracted as prediction information, and the control at 12 to 18 o'clock is performed. The longest accumulated stay time section B is extracted as prediction information among the accumulated stay time sections to which the corresponding time periods corresponding to the last three days corresponding to the target time period belong, and the latest corresponding to the control target time period from 18:00 to 24:00 The longest accumulated stay time section A among the accumulated stay time sections to which the corresponding time zones of the past three days belong is extracted as the prediction information.

  The output determination unit 9b is configured to output the output of the temperature controller 2 in each control target time zone in the automatic operation mode based on the accumulated stay time segment (that is, the prediction information) corresponding to the control target time zone extracted by the extraction unit 8. The longer the accumulated stay time, the higher the output.

  Specifically, when the accumulated stay time section corresponding to the control target time zone extracted by the extraction means 8b is “A”, the output determination unit 9b increases the output of the temperature controller 2 in the control target time zone. If the extracted accumulated stay time section is “B”, the output of the temperature controller 2 in the control target time zone is set to a low output, and the extracted accumulated stay time section is In the case of “C”, the operation of the temperature controller 2 in the control target time zone is stopped.

  And the control part 4 controls the driving | operation of the temperature regulator 2 based on the output set by the said output determination means 9b for the output of each control time slot | zone in a control object day in automatic operation mode.

  In the toilet room temperature control apparatus of the present embodiment described above, the accumulated stay time segment obtained by extracting the output of the temperature controller 2 in each control target time zone in the automatic operation mode by the extraction means 8b, that is, the control target Based on the accumulated stay time section to which the longest of the accumulated stay times in the same time zone of the past multiple days of the day belongs, the longer stay time of the accumulated stay time section is determined to be higher output. For this reason, in the control target time zone where the staying time is expected to be short or unused, the output of the temperature controller 2 is reduced or the operation of the temperature controller 2 is stopped to realize energy saving. it can. In addition, in the control target time zone that is expected to be used by the user who has stayed for a long time, the temperature controller 2 is set to a high output so that the temperature of the toilet room 1 can be surely and quickly set to the optimum set temperature for the user. It is possible to optimize the temperature environment of the toilet room 1 with the user having a long stay time as the top priority.

(Embodiment 3)
This embodiment is an embodiment corresponding to claim 3. In the following description of the present embodiment, the same components as those in the first embodiment are given the same numbers, and redundant descriptions are omitted. In addition, the extraction unit 8 and the output determination unit 9 of the present embodiment are referred to as an extraction unit 8c and an output determination unit 9c, respectively.

  As shown in FIG. 5, the extraction unit 8 c of the present embodiment is based on the data stored in the storage unit 5, and is the longest of the average staying times of the toilet room 1 for the same time period in the past plural days of the control target day. It is determined which of the plurality of average stay time sections divided by the threshold of one or more time belongs to which average stay time section, and the average stay time section is extracted as prediction information.

  In the present embodiment, average stay time sections A to C divided by thresholds of 0 minutes and 3 minutes are provided, and the extraction means 8 is configured to average stay in the toilet room 1 for the same time period in the past plural days of the control target day. It is determined which of the average stay time sections A to C the longest time belongs to, and the average stay time section is extracted as prediction information.

  Specifically, the extraction means 8c first calculates the average stay time in each time zone based on the detected stay time in each time zone, and the average stay time exceeds the upper threshold of 3 minutes. If the average time spent is less than 3 minutes and exceeds the lower threshold of 0 minutes, the time zone is classified as average stay time class B. If the average stay time is 0 minutes (that is, the toilet room 1 is not used in that time zone), the time zone is classified into the average stay time category C.

  For example, in the example of FIG. 5, on the first day (3 days before the control target day), the toilet room 1 was not used in the time zone of 0-6 o'clock, so the time zone was classified into the average stay time category C, Since the average staying time exceeded the upper threshold of 3 minutes in the 6-12 o'clock time zone, the time zone was classified into the average staying time category A, and the time zone of 12-18 o'clock and the time of 18: 00-24 o'clock In the zone, the average stay time did not exceed 3 minutes and exceeded the lower threshold value of 0 minutes, so each time zone was classified into the average stay time category B, and the second day (the day before the control target day) ) And the third day (the day before the control target day) are also classified into any of the average stay time categories A to C.

  Next, the extraction means 8c selects, for each control target time zone, an average stay time section that has the longest average stay time among the average stay time sections to which the corresponding time periods of the most recent three days belong. Extract as forecast information. That is, the extraction unit 8c of the present embodiment determines which average stay time section the time period belongs to for each time period of the past plural days corresponding to the control target time period, and By extracting the longest one, the average stay time section to which the longest one of the average stay times in the same time zone in the past multiple days belongs is extracted.

  For example, in the example of FIG. 5, the longest average stay time section C is extracted as the prediction information among the average stay time sections to which the corresponding time periods corresponding to the last three days corresponding to the control target time period from 0 to 6:00 belong. , The longest average stay time section A is extracted as prediction information among the average stay time sections to which the corresponding time periods corresponding to the last three days corresponding to the control time period from 6 to 12 o'clock belong, and the control at 12 to 18 o'clock is performed.
