The floor heating system can uniformly and evenly heat the entire heating target room by utilizing the heat radiation, conduction, and convection generated by heating the floor material with the floor heating panel. However, in the floor heating system, in order to heat the entire heating target room evenly and evenly, it is necessary to absorb the heat from the floor heating panel to the walls and ceiling of the heating target room, so that a comfortable room temperature is achieved. It is known that it takes time to obtain. Therefore, in order to use the floor heating device to warm the room temperature of the room to be heated to a comfortable temperature by the time when a comfortable room temperature is required, the user needs to warm the room to be heated from the start of operation of the floor heating device.

Must be entered in.

However, in order for the user to accurately estimate the above-mentioned required time, it is necessary to consider the structure of the heating target room (for example, heat insulation) and the outside air temperature, so that the above-mentioned required time can be accurately estimated. It is difficult to do so, and if the above-mentioned estimation of the required time is incorrect, the room temperature of the room to be heated cannot be kept warm to a comfortable temperature by the time when a comfortable room temperature is required.

Therefore, in the floor heating system, the control device (control means) starts the heating operation based on the network information including the weather data and the thermal environment data of each room recorded in the server on the ubiquitous network. (See, for example, Patent Document 1).

When it is determined in the rapid temperature maintenance time arrival determination process that the latest continuous operation time has not reached the rapid temperature maintenance time, the maximum maximum pleasant temperature arrival time initially set in the pre-operation time setting process is set. It is configured to be set to the pre-run time.

If the latest continuous operation time from the required hot temperature time has not reached the high temperature maintenance time, the heat from the floor heating panel may be applied to the wall of the room to be heated during the operation of the floor heating device most recent from the required hot temperature time. Since it is not sufficiently absorbed by the ceiling or the like, the need to consider the amount of heat stored in the wall or ceiling of the room to be heated is greatly reduced when setting the pre-operation time.

In the pre-operation control, the control device 3 performs time information acquisition processing, outside air temperature acquisition processing, pre-operation time acquisition processing, pre-operation start processing, and the like.
In the time information acquisition process, the control device 3 uses the required warming time input by the user, the operation start time of the floor heating device 2, and the operation stop time of the floor heating device 2 as time information related to the operation of the floor heating device 2. , The time to reach a comfortable temperature from the operation start time of the floor heating device 2 until the room temperature of the heating target room 1 reaches a comfortable temperature, and the continuous stop time from the operation stop time to the operation start time are acquired.
In the outside air temperature acquisition process, the control device 3 acquires and acquires the outside air temperature while the operation of the floor heating device 2 is stopped by using the outside air temperature detector 15 provided in the heat source device 6 of the floor heating device 2.

Specifically, the control device 3 performs the first arithmetic processing, the relational information acquisition processing, the second arithmetic processing, the extraction processing, and the pre-operation time setting processing as the pre-operation time acquisition processing. Then, in the first calculation process, the time to reach the comfortable temperature immediately after the continuous stop time is added to obtain the time to reach the comfortable temperature after the stop from the time when the operation is stopped until the room temperature of the heating target room 1 reaches the comfortable temperature. In the relationship information acquisition process, a plurality of continuous stop times, a plurality of pleasant temperature arrival times, a plurality of outside temperatures acquired in the last few days (for example, 7 days), and a plurality of post-stop pleasant times obtained in the last few days are performed. Based on the temperature arrival time, the relationship information showing the relationship between the continuous stop time, the rapid temperature arrival time immediately after the stop, the rapid temperature arrival time after the stop, and the outside air temperature is generated (see FIG. 2). In the second calculation process, the back-calculated rapid temperature arrival time from the required rapid temperature time to the previous operation stop time is obtained. In the extraction process, the back calculation is performed based on the related information, the back calculation speed arrival time, and the latest outside air temperature acquired during the continuous stop time (during the operation stop of the floor heating device 2) included in the back calculation speed arrival time. The time to reach a pleasant temperature after stopping is extracted, which is similar to the time to reach a temperature. Specifically, for example, if the related information is shown in FIG. 2 and the back-calculated rapid temperature arrival time is 8 hours, January 13th, regardless of the latest outside air temperature (January 15th outside air temperature). Eight hours, which is the time to reach a good temperature after the stoppage of, is extracted. Further, for example, if the related information is shown in FIG. 2, the back-calculated rapid temperature arrival time is 6.5 hours, and the latest outside air temperature is 5 ° C., the post-stop rapid temperature similar to the reverse-calculated rapid temperature arrival time. Since there are 7 hours on January 12th and 14th, the arrival time is the time to reach the pleasant temperature after the stop on January 12th, which corresponds to the outside air temperature (5 ℃) similar to the latest outside temperature (5 ℃). Extract (7 hours). In the pre-operation time setting process, the pleasant temperature arrival time included in the extracted after-stop pleasant temperature arrival time is set as the pre-operation time. Specifically, for example, if the extracted hot temperature arrival time after stopping is 8 hours on January 13, 1 hour, which is the free temperature arrival time included in these 8 hours, is set as the pre-operation time. .. Further, for example, if the extracted hot temperature arrival time after stopping is 7 hours on January 12, 1 hour, which is the free temperature arrival time included in the 7 hours, is set as the pre-operation time.
In the pre-operation start processing, the control device 3 starts the operation of the floor heating device 2 at the pre-operation time that is retroactive from the pre-operation time from the required free temperature time.

The outside temperature, etc. are taken into consideration.

As a result, when the control device 3 acquires the required hot temperature time input by the user, the control device 3 performs the time information acquisition process, the pre-operation time acquisition process, and the pre-operation start process described above to form the structure of the heating target room 1. It is possible to obtain an appropriate pre-operating time considering the amount of heat stored in the walls and ceiling of the heating target room 1, the outside temperature around the heating target room, etc., and the pre-operation time from the required warming time. The operation of the floor heating device 2 can be started at an appropriate pre-operation time retroactively.

Further, the control device 3 reaches a plurality of continuous stop times and a plurality of pleasant temperatures acquired or obtained in the last few days in which the difference in the outside air temperature and the like, which affects the acquisition of the pre-operation time, is small in the related information acquisition process. Relationship information is generated based on the time and a plurality of post-stop hot temperature arrival times, and in the extraction process, the back-calculated hot temperature arrival time similar to the back-calculated hot temperature arrival time obtained in the second calculation process of the related information is reached. Set the warm temperature arrival time included in the time to the pre-operation time. Then, when the control device 3 has a plurality of post-stop hot temperature arrival times similar to the back-calculated free temperature arrival time, the control device 3 sets the hot temperature arrival time included in the post-stop hot temperature arrival time suitable for the latest outside air temperature. Set to pre-run time.

As a result, the control device 3 can acquire the pre-operation time in which the outside air temperature and the like are taken into consideration more appropriately, and thereby, the operation of the floor heating device 2 can be started at a more appropriate pre-operation time. Therefore, the room temperature of the room 1 to be heated can be more reliably warmed to a comfortable temperature by the time when a comfortable room temperature is required.

[Another Embodiment]
The present invention is not limited to the configurations exemplified in the above-described embodiments, and the following, typical alternative embodiments relating to the present invention will be exemplified.

[1] The floor heating system may be an electric type in which an electric heater is embedded in the floor heating panel 5.

[2] In the floor heating system, the control device 3 is set to connect wirelessly to a mobile communication terminal such as a smartphone or tablet, and the control device 3 is an alarm that the user has registered in the mobile communication terminal in the time information acquisition process. It may be configured to acquire and store the time as a required warm temperature time.

[3] In the related information acquisition process, the control device 3 has a plurality of continuous stop times and a plurality of pleasant temperature arrival times acquired or obtained as the most recent several days, for example, 8 days or more or 6 days or less. It may be configured to generate the above-mentioned relationship information based on a plurality of times when the temperature reaches a high temperature after stopping.

[4] As shown in FIG. 3, in the time information acquisition process, the control device 3 uses the time information related to the operation of the floor heating device 2 in addition to the free temperature arrival time and the continuous stop time of the floor heating device 2. It is possible to acquire the continuous operation time from the operation start time to the operation stop time of the floor heating device 2 and maintain the room temperature of the heating target room 1 at a comfortable temperature for a predetermined time by the latest continuous operation time from the required time for high temperature. The rapid temperature maintenance time arrival determination process for determining whether or not the comfortable temperature maintenance time (for example, 2 hours) has been reached is performed, and the latest continuous operation time reaches the pleasant temperature maintenance time in the rapid temperature maintenance time arrival determination process. If it is determined that the pre-operation time has been obtained, in the pre-operation time acquisition process, the pre-operation time required for the room temperature of the heating target room 1 to reach the comfortable temperature at the required time for a pleasant temperature based on the time information regarding the operation of the floor heating device 2. If it is determined in the rapid temperature maintenance time arrival determination process that the latest continuous operation time has not reached the rapid temperature maintenance time, the maximum maximum pleasant temperature arrival time initially set in the pre-operation time setting process ( For example, 3 hours) may be set as the pre-operation time.
This is because when the latest continuous operation time from the required time for free temperature has not reached the maintenance time for high temperature, the heat from the floor heating panel 5 is heated during the operation of the floor heating device 2 most recent from the required time for free temperature. Since it is not sufficiently absorbed by the wall or ceiling of the target room 1, the need to consider the amount of heat stored in the wall or ceiling of the heating target room 1 is greatly reduced when setting the pre-operation time.
In consideration of this point, in this alternative embodiment, when the latest continuous operation time from the required free temperature time has not reached the high temperature maintenance time, the control device 3 sets the initial maximum free temperature arrival time. Is set to the pre-running time. As a result, the control device 3 does not need to perform arithmetic processing or related information acquisition processing in the pre-operation time acquisition processing when the latest continuous operation time from the required free temperature time has not reached the high temperature maintenance time.
As a result, when the latest continuous operation time from the required time for pleasant temperature has not reached the pleasant temperature maintenance time, an appropriate pre-operation time can be set while reducing the burden on the control device 3.

[5] As shown in FIG. 3, in the time information acquisition process, the control device 3 uses the time information related to the operation of the floor heating device 2 in addition to the free temperature arrival time and the continuous stop time of the floor heating device 2. It is possible to acquire the continuous operation time from the operation start time to the operation stop time of the floor heating device 2 and maintain the room temperature of the heating target room 1 at a comfortable temperature for a predetermined time by the latest continuous operation time from the required time for high temperature. The first determination process (commitment processing for reaching the pleasant temperature maintenance time) for determining whether or not the comfortable temperature maintenance time (for example, 2 hours) has been reached, and whether or not the back-calculated rapid temperature arrival time exceeds the predetermined time described above. The second determination process is performed, and the first determination process determines that the latest continuous operation time has reached the pleasant temperature maintenance time, and the second determination process determines the back-calculated express temperature arrival time. If it is determined that the time has not been exceeded, the pre-operation time may be set to zero in the pre-operation time setting process.
This is because when the latest continuous operation time from the required hot temperature time has reached the high temperature maintenance time, the heat from the floor heating panel 5 is heated during the operation of the floor heating device 2 most recent from the required hot temperature time. If it is sufficiently absorbed by the walls and ceiling of the target room 1 and the back calculation rapid temperature arrival time does not exceed the above-mentioned predetermined time, the amount of heat storage in the walls and ceiling of the heating target room 1 is small. Therefore, it is presumed that the room temperature of the heating target room 1 is maintained at a comfortable temperature.
In consideration of this point, in this other embodiment, the continuous operation time most recent from the required time for free temperature has reached the high temperature maintenance time, and the back calculation quick temperature arrival time does not exceed the above-mentioned predetermined time. In this case, the control device 3 sets the pre-operation time to zero.
As a result, if the continuous operation time most recent from the required time for the hot temperature has reached the high temperature maintenance time and the back calculation quick temperature arrival time does not exceed the predetermined time described above, the pre-operation time It is possible to prevent unnecessary pre-operation of the floor heating device 2 without performing arithmetic processing or related information acquisition processing in the acquisition process.
