(Floor heating device 10)
The configuration of the floor heating device 10 according to this embodiment will be described. FIG. 1 is a schematic diagram showing an example of a floor heating device 10 according to this embodiment.

The floor heating device 10 shown in FIG. 1 is a device that heats a floor material 102 placed in a living room 104 and heats the living room 104 by radiant heat from the heated floor material 102 . In this embodiment, an air conditioner 100 (an example of another heating device) is installed in a living room 104 in which the floor heating device 10 is installed. The air conditioner 100 is attached to the side wall 109 of the living room 104, for example.

The air conditioner 100 is installed at a position where the height H1 from the floor surface 106 is approximately 2100 mm, for example. A height HA (see FIG. 1) from the floor surface 106 to the ceiling 108 of the living room 104 is, for example, 2400 mm.

Here, the floor heating device 10 operates independently of the air conditioner 100 . That is, each of the floor heating device 10 and the air conditioner 100 has a separate control device and operation unit, and each operation is controlled by each control device based on instructions input by the user through each operation unit. be done. Further, the floor heating device 10 does not have means for communicating with the air conditioner 100 and is configured such that information cannot be obtained from the air conditioner 100 . Therefore, the floor heating device 10 cannot directly acquire information such as an instruction input through the operation unit of the air conditioner 100 and the operation status of the air conditioner 100 (whether it is operating or not) from the air conditioner 100. It is configured.

Furthermore, a part of living room 104 constitutes kitchen 110 . A kitchen remote controller 112 is installed in the kitchen 110 . A later-described heating unit 20 of the floor heating device 10 functions as a water heater, and the kitchen remote controller 112 can operate the water heater. The operation includes an on/off operation of the water heater, an operation of setting the temperature of the hot water supply, and the like. Furthermore, the kitchen remote control 112 is equipped with an audio speaker 114 . In this embodiment, the kitchen remote controller 112 is connected to a control device 60 of the floor heating device 10, which will be described later, by a wire or the like, so that communication is possible. Note that the kitchen 110 portion may have a configuration in which the warm water mat 22 is not arranged.

Specifically, the floor heating device 10 includes a heating section 20, an operation section 30, a room temperature sensor 40, and a control device 60, as shown in FIG. The configuration of each part of the floor heating device 10 will be described below.

(Heating section 20)
The heating unit 20 shown in FIG. 1 is a component that heats the floor material 102 . In this embodiment, the heating unit 20 is a warm water type heating unit, and includes, for example, a warm water mat 22 , a heater 24 , a circulation pipe 26 and an on-off valve 28 .

The warm water mat 22 is arranged on the lower side of the floor material 102 and is in contact with the floor material 102 so as to be able to conduct heat. The circulation pipe 26 is a pipe for circulating hot water as a heat medium between the hot water mat 22 and the heater 24 . One end and the other end of the circulation pipe 26 are connected to the heater 24, and the intermediate portion is arranged inside the warm water mat 22 so as to meander in plan view. The heater 24 heats the hot water circulating in the circulation pipe 26 . The on-off valve 28 is provided on the circulation pipe 26 . By opening the on-off valve 28, the circulation pipe 26 is opened and hot water is circulated in the circulation pipe 26, and by closing the on-off valve 28, the circulation pipe 26 is closed and the circulation of hot water in the circulation pipe 26 is stopped. do.

In the heating unit 20 , the warm water heated by the heater 24 is circulated between the warm water mat 22 and the heater 24 through the circulation pipe 26 to heat the floor material 102 . In other words, the hot water heated by the heater 24 is continuously sent to the flooring material 102 through the circulation pipe 26 to heat the flooring material 102 .

In the heater 24, the temperature for heating the hot water circulating in the circulation pipe 26 (hereinafter referred to as heating temperature) can be changed. In addition, in the heater 24, the flow rate of hot water can be changed by opening and closing the on-off valve 28 to circulate the hot water or stop the circulation of the hot water. In the heating unit 20, by changing the heating temperature of the hot water and the flow rate of the hot water, the amount of heat per unit time for heating the floor material 102 (hereinafter referred to as the amount of heating heat) can be adjusted. .

Furthermore, in the present embodiment, the heating unit 20 is capable of executing individual operation, combined operation, and hot dash operation, for example. Single operation or combined operation is an example of steady operation.

The isolated operation is an operation that is performed when it is determined that the air conditioner 100 is not operating, that is, when it is determined that the floor heating device 10 is operating alone. In single operation, the heating unit 20 heats the floor material 102 with a predetermined amount of heating heat. In the present embodiment, the heating unit 20 circulates hot water at a reference temperature (eg, 60° C.) during single operation. Note that the reference temperature is not limited to 60° C. in the present embodiment. Various temperatures can be set as the reference temperature, and for example, the temperature can be set within the range of 40° C. or higher and 60° C. or lower.

The combined operation is an operation that is executed when it is determined that the air conditioner 100 is operating in combination with the floor heating device 10 . In the combined operation, the heating unit 20 heats the floor material 102 with a heating heat amount lower than that in the single operation. That is, in the combined operation, the heating unit 20 reduces the amount of heating heat per unit time as compared with the case of the independent operation. As a result, in the combined operation, the floor material 102 is heated to a lower temperature than in the single operation. In the present embodiment, the heating unit 20 circulates hot water at a reference low temperature (for example, 40° C.) lower than the reference temperature in the combined operation. The reference low temperature is, for example, the lowest temperature of hot water that can be circulated in the heating unit 20 . In this embodiment, the reference low temperature is not limited to 40° C., and can be set to various temperatures as long as the reference low temperature is lower than the reference temperature.

The hot dash operation is an operation that is executed when the floor heating device 10 is started up (that is, when the living room 104 is not warmed up). In the hot dash operation, the heating unit 20 heats the floor material 102 with an amount of heating heat higher than that in the single operation. As a result, in the hot dash operation, the floor material 102 is heated to a higher temperature than in the single operation. In this embodiment, the heating unit 20 circulates hot water having a reference temperature (for example, 70° C.) higher than the reference temperature in the hot dash operation. The reference high temperature is, for example, the maximum temperature of hot water that can be circulated in the heating unit 20 . In this embodiment, the reference high temperature is not limited to 70° C. The reference high temperature can be set to various temperatures as long as the temperature is higher than the reference temperature.

(Operation unit 30)
An operation unit 30 shown in FIG. 1 is a component for performing various operations by a user of the floor heating device 10 (hereinafter referred to as a user). The user's operations include, for example, an on/off operation of the floor heating device 10 and an operation of setting the room temperature.

The on/off operation of the floor heating device 10 by the user determines whether or not to operate the floor heating device 10 . That is, the user can input an operation instruction to operate the floor heating device 10 and a stop instruction to stop the operation of the floor heating device 10 through the operation unit 30 .

Further, the room temperature desired by the user is set by the user's room temperature setting operation. That is, the user can input the set temperature as the desired room temperature through the operation unit 30 .

The operation unit 30 transmits instructions (such as the above-described operation instructions) and information (such as set temperature information) input by the user to the control device 60 .

In this embodiment, the operation unit 30 is configured by, for example, a remote controller. This operation unit 30 is installed, for example, on the side wall 109 of the living room 104 . Also, the operation unit 30 is installed at a position where the height H2 (see FIG. 1) from the floor surface 106 is, for example, about 1100 mm.

A room temperature sensor 40 shown in FIG. 1 is an example of a detection unit, and is a sensor that detects the room temperature of living room 104 . The room temperature sensor 40 is provided in the operation section 30, for example. Therefore, the room temperature sensor 40 is installed at a height of about 1100 mm from the floor surface 106, for example.

The room temperature sensor 40 , for example, detects the room temperature of the living room 104 at predetermined intervals and sends information on the detected room temperature to the control device 60 .

(control device 60)
The control device 60 is an example of a control section, and is a device that controls the operation of the heating section 20 . Specifically, the control device 60 has a processor 61, a memory 62, a storage 63, and a timer 64, as shown in FIG. Note that the processor 61 may be understood as an example of a control unit.

As the processor 61, for example, a CPU (Central Processing Unit), which is a general-purpose processor, is used. An example of the processor may be a dedicated processor composed of a circuit designed exclusively for executing specific processing.

The storage 63 stores various programs including a control program 63A (see FIG. 3) and various data. The storage 63 is specifically implemented by a recording device such as a HDD (Hard Disk Drive), SSD (Solid State Drive), flash memory, or the like.

The memory 62 is a work area for the processor 61 to execute various programs, and temporarily records various programs or various data when the processor 61 executes processing. The processor 61 reads various programs including the control program 63A from the storage 63 to the memory 62 and executes the programs using the memory 62 as a work area. The timer 64 is a measuring unit for measuring various times such as a first reference time, a second reference time, a first time, a second time, and a cycle time, which will be described later.

In the control device 60, the processor 61 implements various functions by executing the control program 63A. A functional configuration realized by cooperation between the processor 61 as a hardware resource and the control program 63A as a software resource will be described below. FIG. 3 is a block diagram showing the functional configuration of the processor 61. As shown in FIG.

As shown in FIG. 3, in the control device 60, the processor 61 functions as an acquisition unit 61A, a driving situation determination unit 61C, a notification control unit 61D, and an operation control unit 61E by executing a control program 63A.

The acquisition unit 61A is a functional unit that acquires various instructions and information input by the user through the operation unit 30. FIG. In the present embodiment, the acquisition unit 61A acquires at least the operation instruction input by the user through the operation unit 30 and information on the set temperature. Acquisition unit 61A also acquires information on the room temperature detected by room temperature sensor 40 from room temperature sensor 40 .

The operating status determination unit 61C determines whether or not the air conditioner 100 is operating based on the temperature change (specifically, the change over time) of the room temperature detected by the room temperature sensor 40 . Specifically, for example, the operating condition determination unit 61C determines that the temperature rise in the first reference time (for example, 10 minutes) of the room temperature detected by the room temperature sensor 40 is greater than or equal to the reference rise (for example, 4°C). Driving condition determination is performed by determining whether or not.

Note that the first reference time is not limited to 10 minutes, and can be set to various times. Further, the reference rise width is not limited to 4° C., and can be set to various rise widths.

The operating condition determination unit 61C determines that the air conditioner 100 is operating when determining that the temperature increase range is equal to or greater than the reference increase range. When the operating condition determination unit 61C determines that the temperature increase width is less than the reference increase width, it determines that the air conditioner 100 is not operating.

Although the operating condition determination unit 61C determines whether or not the temperature increase range in the first reference time of the room temperature is equal to or greater than the reference increase range, the operating condition determination is not limited to this. . For example, the driving condition determination unit 61C may determine the driving condition based on the slope of the temperature in the first reference time of the room temperature.

When the floor heating device 10 is activated through the operation unit 30 (that is, the ON operation is performed by the operation unit 30) and the operation of the floor heating device 10 is started, the operation state determination unit 61C determines the initial operation state. make a judgment. Specifically, the driving condition determination unit 61C starts the hot dash operation when the floor heating device 10 is turned on, and performs the first driving condition determination after a predetermined time has elapsed. Further, the driving condition determination unit 61C performs the driving condition determination again after finishing the hot dash driving.

The notification control unit 61D is a functional unit that controls the notification unit to execute a notification that prompts (promotes) the operation of the air conditioner 100 (hereinafter referred to as a promotion notification). Specifically, when the operating condition determination unit 61C determines that the air conditioner 100 is not in operation, the notification control unit 61D controls the voice speaker provided in the kitchen remote controller 112 to execute the prompt notification by voice. 114. The operation condition determination by the operation condition determination unit 61C is the first operation condition determination after the floor heating device 10 is started.

Therefore, in the present embodiment, the notification control unit 61D, when determining that the air conditioner 100 is not in operation in the operation status determination performed first after the floor heating device 10 is started, notifies the promotion. Control to be executed by voice is performed on the voice speaker 114 .

The notification control unit 61D does not control the audio speaker 114 to execute the promotion notification by voice when the driving condition determination unit 61C determines that the air conditioner 100 is operating. Note that the audio speaker 114 is an example of a notification unit.

The operation control unit 61E is a functional unit that controls the operation of the heating unit 20 (that is, the operation state). In this embodiment, the operation control unit 61E operates the heating unit 20 based on the operation status of the air conditioner 100, the instruction acquired by the acquisition unit 61A, the detection result of the room temperature sensor 40, and the like. Specifically, the operation control unit 61E controls the operating state of the heating unit 20 as follows.

The operation control unit 61E, when the operating condition determining unit 61C determines that the air conditioner 100 is operating, performs hot dash operation more than when the operating condition determining unit 61C determines that the air conditioner 100 is not operating. The heating unit 20 is controlled to shorten the operation time of .

Further, when the operating condition determining unit 61C determines that the air conditioner 100 is operating, the operation control unit 61E controls the floor more than when the operating condition determining unit 61C determines that the air conditioner 100 is not operating. The heating unit 20 is controlled to reduce the amount of heat per unit time for heating the material 102 . Specifically, when the operation control unit 61E determines that the air conditioner 100 is operating as a result of the operation condition determination unit 61C performing the operation condition determination after the hot dash operation is completed, the operation control unit 61E , the heating unit 20 is controlled to lower the amount of heat per unit time for heating the floor material 102 than when the operating state determination unit 61C determines that the air conditioner 100 is not in operation.

Further, the operation control unit 61E controls the heating unit 20 to decrease the amount of heat per unit time for heating the floor material 102 by decreasing the temperature of the hot water in the heating unit 20 . Further, the operation control unit 61E controls the heating unit 20 to reduce the amount of heat per unit time for heating the floor material 102 by adjusting the flow rate of hot water in the heating unit 20 . Specifically, as will be described later, the operation control unit 61E controls the heating unit 20 to reduce the amount of heat per unit time for heating the floor material 102 by executing duty control (flow rate adjustment). conduct.

(Control processing according to the present embodiment)
Next, an example of control processing according to this embodiment will be described.

FIG. 4 is a flowchart showing an example of the flow of control processing executed by the control device 60. As shown in FIG. FIG. 5 is a flow chart showing an example of the flow of the islanding operation that the heating unit 20 is caused to execute in the control process executed by the control device 60. As shown in FIG. FIG. 6 is a flow chart showing an example of the flow of the combined operation that the heating unit 20 is caused to execute in the control process executed by the control device 60. As shown in FIG.

This control process is performed by processor 61 reading control program 63A from storage 63 and executing it. Execution of this control process is started, for example, when the floor heating device 10 is turned on through the operation unit 30 .

As shown in FIG. 4, when starting this control process, the processor 61 causes the heating unit 20 to start the hot dash operation (step S102).

Next, the processor 61 determines whether or not the air conditioner 100 is operating based on the change in room temperature detected by the room temperature sensor 40 (step S104). Specifically, the processor 61 determines whether the temperature rise in the first reference time (for example, 10 minutes) of the room temperature detected by the room temperature sensor 40 is equal to or greater than the first reference rise (for example, 4° C.). By determining the driving situation is determined. The operating condition determination is the first operating condition determination after the floor heating device 10 is started up.

Note that the first reference time is, for example, the time from when the heating unit 20 starts the hot dash operation (step S102). Also, the first reference time is not limited to 10 minutes, and can be set to various times. Further, the first reference increase width is not limited to 4° C., and can be set to various increase widths.

The processor 61 determines that the air conditioner 100 is operating (step S104: YES) when determining that the temperature rise width is greater than or equal to the first reference rise width, and the hot dash operation is performed by the heating unit 20. is executed for a predetermined first time (for example, 30 minutes) (step S106), and the process proceeds to step S110.

On the other hand, when the processor 61 determines that the temperature rise width is less than the first reference rise width, the processor 61 determines that the air conditioner 100 is not operating (step S104: NO), and stops the air conditioner 100 from operating. The voice speaker 114 provided in the kitchen remote controller 112 is caused to issue a prompting notification to prompt (promote) (step S107), and the process proceeds to step S108. The promotion notification is performed, for example, by playing an announcement such as "The floor heating system has started. Starting the heating operation of the air conditioner will also save energy." In addition, in step S106, the notification by the audio speaker 114 is not performed.

In step S108, the processor 61 causes the heating unit 20 to perform the hot dash operation for a predetermined second time (for example, 60 minutes), and proceeds to step S110.

In this embodiment, the first time is shorter than the second time. That is, in the present embodiment, when the processor 61 determines that the air conditioner 100 is operating, the processor 61 causes the heating unit 20 to perform hot dash more than when it determines that the air conditioner 100 is not operating. Shorten driving time.

In step S<b>110 , the processor 61 determines whether or not the air conditioner 100 is operating based on the change in room temperature detected by the room temperature sensor 40 . Specifically, the processor 61 determines whether the temperature rise width of the room temperature detected by the room temperature sensor 40 in the second reference time (for example, 20 minutes) is equal to or greater than the second reference rise width (for example, 4° C.). By determining the driving situation is determined.

Note that the second reference time is, for example, the time that goes back from the point in time when the heating unit 20 ends the hot dash operation in the first driving condition determination performed after the hot dash operation ends. Although the second reference time is longer than the first reference time in this embodiment, they may be the same. Furthermore, the second reference time may be shorter than the first reference time. The second reference time is not limited to 20 minutes, and can be set to various times.

Also, the second reference rise width is the same temperature width as the first reference rise width, but may have a different temperature width. For example, the second reference rise width may be a wider temperature range than the first reference rise width. The second reference rise width is not limited to 4° C., and can be set to various rise widths.

The processor 61 determines that the air conditioner 100 is operating (step S110: YES) when determining that the temperature rise width is equal to or greater than the second reference rise width, and instructs the heating unit 20 to perform the combined operation. Execute (step S200) and return to step S110.

On the other hand, when the processor 61 determines that the temperature rise width is less than the second reference rise width, the processor 61 determines that the air conditioner 100 is not operating (step S110: NO). 20 (step S300) and returns to step S110.

In this embodiment, the processor 61 returns to step S110 after executing one of the combined operation and the individual operation for a predetermined time (hereinafter referred to as cycle time).

In other words, the processor 61 executes the driving situation determination of step S110 for each cycle time. The second reference time is the cycle time in the second and subsequent driving condition determinations performed after one of the combined operation and the individual operation is performed. Note that the cycle time is, for example, the same time as the second reference time, specifically, for example, 20 minutes. The cycle time is not limited to 20 minutes and can be set to various times.

(single operation)
As shown in FIG. 5, when the processor 61 starts the individual operation (step S300) of the heating unit 20, the heating unit 20 starts circulating hot water at a reference temperature (eg, 60° C.). (step S304), and the process proceeds to step S306.

In this embodiment, in steps S306 and S307, the processor 61 performs duty control (flow rate adjustment) based on the room temperature detected by the room temperature sensor 40 . Specifically, the opening time (ON time) for opening the on-off valve 28 and the closing time (OFF time) for closing the on-off valve 28 within the cycle time described above are determined based on the room temperature detected by the room temperature sensor 40. be.

The open time (ON time) and closed time (OFF time) are determined, for example, based on the room temperature detected by the room temperature sensor 40 each time individual operation is performed.

Then, in step S306, hot water is circulated during the open time (ON time) determined based on the room temperature detected by the room temperature sensor 40. FIG.

Next, in step S307, the hot water circulation is stopped during the closed time (OFF time) determined based on the room temperature detected by the room temperature sensor 40, and the process returns to step S110. It should be noted that the above procedure of the islanding operation is an example, and various procedures can be used as the islanding operation.

(Combined operation)
As shown in FIG. 6, when the combined operation (step S200) is started, the processor 61 starts circulation of hot water at a reference low temperature (for example, 40° C.) in the heating unit 20 (step S204). , the process proceeds to step S206.

In this embodiment, in steps S206 and S207, the processor 61 performs duty control (flow rate adjustment) based on the room temperature detected by the room temperature sensor 40 . Specifically, the opening time (ON time) for opening the on-off valve 28 and the closing time (OFF time) for closing the on-off valve 28 within the cycle time described above are determined based on the room temperature detected by the room temperature sensor 40. be.

The open time (ON time) and closed time (OFF time) are determined based on the room temperature detected by the room temperature sensor 40, for example, each time the combined operation is performed.

Then, in step S206, warm water is circulated during the open time (ON time) determined based on the room temperature detected by the room temperature sensor 40. FIG.

Next, in step S207, the hot water circulation is stopped during the closed time (OFF time) determined based on the room temperature detected by the room temperature sensor 40, and the process returns to step S110. It should be noted that the above procedure of the combined operation is an example, and various procedures can be used as the combined operation.

Note that in this control process, when the floor heating device 10 is turned off via the operation unit 30, this control process ends regardless of which step is being executed.

As described above, in the combined operation, the amount of heat per unit time is reduced by lowering the hot water temperature in the heating unit 20 compared to the single operation. Furthermore, in the present embodiment, the temperature of the hot water in the heating unit 20 is lowered, and duty control (flow rate adjustment) is performed based on the room temperature detected by the room temperature sensor 40, so that the floor heating device 10 is used as an auxiliary air conditioner 100. act as a heater. Therefore, the ratio of the heating load between the air conditioner 100 and the floor heating device 10 is lower for the floor heating device 10 than for the air conditioner 100 . That is, the amount of heat for heating the living room 104 (the amount of heat for maintaining the room temperature of the living room 104 ) is lower than the amount of heat by the floor heating device 10 and the air conditioner 100 . Furthermore, when the floor heating device 10 is operated as auxiliary heating of the air conditioner 100, the floor heating device 10 is adjusted so that the floor temperature (surface temperature) of the floor material 102 is maintained at, for example, 25 ° C. or higher. The heating unit 20 heats the floor material 102 .

(Effects of this embodiment)
As described above, in the floor heating device 10 according to the present embodiment, the operation control unit 61E determines that the air conditioner 100 is not operating when the operating condition determination unit 61C determines that the air conditioner 100 is operating. The heating unit 20 is controlled to shorten the operating time of the hot dash operation more than when the driving condition determination unit 61C determines that

As a result, when the operation control unit 61E determines that the air conditioner 100 is in operation and the operation condition determination unit 61C determines that the air conditioner 100 is not in operation, the hot dash Energy saving can be achieved compared with the configuration with the same or longer operation time.

In addition, in the present embodiment, the driving condition determination unit 61C performs the driving condition determination again after the hot dash driving is finished.

Therefore, it is possible to determine that the operating status of the air conditioner 100 has changed after the operating status determination unit 61C has made the first operating status determination and after the hot dash operation has ended.

Further, in the present embodiment, the operation control unit 61E determines that the air conditioner 100 is not operating when the operating condition determination unit 61C determines that the air conditioner 100 is operating. The heating unit 20 is controlled to reduce the amount of heat per unit time for heating the floor material 102 more than the case.

Therefore, when the operation control unit 61E determines that the air conditioner 100 is operating and the operation condition determination unit 61C determines that the air conditioner 100 is not operating, the unit time Energy can be saved as compared with a configuration in which the amount of heat per unit is the same or longer.

(Modified example of control processing)
In the control process shown in FIG. 4, in step S107, the processor 61 causes the audio speaker 114 to execute the prompting notification, and then proceeds to step S108, but the process is not limited to this. For example, as shown in FIG. 7, in step S107, after the processor 61 causes the voice speaker 114 to execute the prompting notification, the driving situation is determined again based on the temperature change in the room temperature detected by the room temperature sensor 40. (step S130). This is done in order to confirm whether or not the user has started the operation of the air conditioner 100 after causing the voice speaker 114 to execute the prompting notification.

In this modification, when it is determined that the air conditioner 100 is operating as a result of step S130 (step S130: YES), the process proceeds to step S106, and when it is determined that the air conditioner 100 is not operating ( Step S130: NO), the process proceeds to step S108.

In addition, in the control process shown in FIG. 4 , in step S107, the processor 61 causes the audio speaker 114 to execute the prompt notification, and then proceeds to step S108. You can move to That is, the configuration may be such that processor 61 does not perform control for executing the promotion notification that prompts (promotes) the operation of air conditioner 100 .

In addition, in the control process shown in FIG. 4, in step S110, the driving condition is determined, and based on the determination result, the heating unit 20 is caused to perform the combined operation or the individual operation, but the present invention is not limited to this. For example, the heating unit 20 may be configured to perform the same operation as the individual operation without performing the operation condition determination in step S110. That is, after the hot dash operation ends, regardless of the operating state of the air conditioner 100, the heating unit 20 may be configured to perform a predetermined operation (for example, an operation similar to the single operation).

(Modified example of combined operation)
In the combined operation (step S200) shown in FIG. 6, the processor 61 performs duty control (flow rate adjustment) based on the room temperature detected by the room temperature sensor 40 in steps S206 and S207, but the present invention is not limited to this. . For example, in steps S206 and S207, the processor 61 may perform duty control (flow rate adjustment) according to a predetermined pattern regardless of the detection result of the room temperature sensor 40. FIG. Specifically, an open time (ON time) for opening the on-off valve 28 and a closed time (OFF time) for closing the on-off valve 28 within the cycle time are determined based on a predetermined pattern.

Then, in step S206 in this modified example, warm water is circulated for an open time (ON time) determined based on a predetermined pattern.

Next, in step S207 in this modification, the hot water circulation is stopped during the closed time (OFF time) determined based on a predetermined pattern, and the process returns to step S110. For example, it can be applied to the floor heating device 10 that does not have the room temperature sensor 40 . Therefore, the floor heating device 10 may adopt a configuration in which the room temperature sensor 40 is not provided.

(Modified example of audio speaker 114 as notification unit)
Although the voice speaker 114 is used as an example of the notification unit in the present embodiment, it is not limited to this. An example of the notification unit may be a voice speaker mounted on the operation unit 30 or the like. In this case, the prompting notification is done by voice. Furthermore, as an example of the notification unit, a terminal such as a smartphone may be used. According to this configuration, for example, the terminal is controlled to execute the promotion notification through the wireless communication means.

Further, as an example of the notification unit, a display unit such as a display screen provided in the operation unit 30 may be used. In this case, the prompt notification is done by display.

(Modified example of air conditioner 100)
In this embodiment, the air conditioner 100 is installed in the room 104 as an example of another heating device, but the present invention is not limited to this. Examples of other heating devices include panel heaters, gas fan heaters, oil heaters, and the like, and various heating devices can be used.

(Modified example of heating unit 20)
In the present embodiment, the heating unit 20 can adjust the heating heat amount of the floor material 102 by changing the heating temperature and flow rate of the hot water circulating in the circulation pipe 26, but the present invention is not limited to this. . For example, the heating unit 20 may be configured to adjust the heating heat amount of the floor material 102 by changing one of the heating temperature and the flow rate of the hot water circulating in the circulation pipe 26, or the heating temperature of the hot water. And in addition to or instead of the flow rate, the heating amount of the floor material 102 may be adjusted according to other conditions.

In this embodiment, the heating unit 20 is of a hot water type, but is not limited to this. The heating unit 20 may be of an electric type. In the electric heating unit, for example, a configuration is conceivable in which a heating element arranged on the lower side of the floor material 102 is heated by energization. In this configuration, for example, the amount of heat for heating the flooring 102 can be adjusted by the electric power that is applied to the heating element.

The present invention is not limited to the above-described embodiments, and various modifications, changes, and improvements are possible without departing from the scope of the invention.
