JP 2017-067417 A JP-A-2002-71147

In the configurations of Patent Documents 1 and 2, when the floor heating system starts operating, it is determined whether or not the air conditioner is also being operated. In practice, it is not determined whether the air conditioner is also being operated. As in Patent Documents 1 and 2, in a configuration in which a combined operation of another heating device is determined when the operation of the floor heating device is started, in the floor heating device including a heating unit for heating the floor material, When operating the heating unit in the steady operation mode, it was not possible to grasp the operation status of other heating devices used together with the floor heating device.

In consideration of the above facts, the present invention provides a floor heating apparatus including a heating unit for heating a floor material, and is used together with the floor heating apparatus when the heating unit is operated in a steady operation mode. An object of the present invention is to make it possible to grasp the operating conditions of other heating devices.

The floor heating device according to the first aspect includes a detection unit that detects room temperature and a heating unit that heats the floor material, and includes a start operation mode used when starting operation, and a start operation mode rather than the start operation mode. a heating unit having a steady operation mode with a small amount of heating heat for heating the floor material; and after starting the operation of the heating unit in the start operation mode, shifting to the steady operation mode, When the detection unit detects the room temperature exceeding the set temperature a predetermined reference number of times in a predetermined reference period after detecting the room temperature exceeding the set temperature, another heating device is in operation. and a determination unit that determines.

Thus, in the configuration of the first aspect, the determination unit causes the heating unit to start operating in the start operation mode, then shifts to the steady operation mode, and the detection unit detects room temperature exceeding the set temperature. After that, when the room temperature exceeding the set temperature is detected a reference number of times in the reference period, it is determined that another heating device is in operation.

Therefore, when the heating unit is operated in the steady operation mode, it is possible to grasp the operating conditions of other heating devices used together with the floor heating device.

In the floor heating device according to the second aspect, the heating unit can stepwise decrease the heating heat amount for heating the floor material from the heating heat amount in the steady operation mode, and the determination unit controls the heating unit to reduce the amount of heat for heating from the amount of heat for heating in the steady operation mode when it is determined that another heating device is in operation.

Therefore, when it is determined that another heating device is in operation, the room temperature is prevented from rising beyond the set temperature of the floor heating device compared to a configuration in which the steady operation mode is continued.

In the floor heating device according to the third aspect, after the determination unit reduces the heating heat amount from the heating heat amount in the steady operation mode, the detection unit detects a room temperature exceeding the set temperature, When the room temperature exceeding the set temperature is again detected for the reference number of times during the reference period, the heating unit is controlled to decrease the amount of heating heat again.

For this reason, after the detection unit detects a room temperature exceeding the set temperature, when the detection unit again detects the room temperature exceeding the set temperature for the reference number of times in the reference period, compared to the configuration in which the heating heat amount of the heating unit is maintained, the room temperature is suppressed from rising beyond the set temperature of the floor heating system.

In the floor heating device according to the fourth aspect, after the determination unit reduces the amount of heating heat, the detection unit detects a room temperature lower than the set temperature, and then determines in a predetermined reference period. When a room temperature lower than the set temperature is detected for the predetermined reference number of times, the heating unit is controlled to restore the amount of heat for heating.

For this reason, after the detection unit detects a room temperature lower than the set temperature, when the detection unit detects a room temperature lower than the set temperature a reference number of times in the reference period, compared to a configuration in which the amount of heating heat is reduced, the floor temperature is reduced. Even when the operation of another heating device that has been operated in combination with the heating device is stopped, the room temperature is prevented from falling below the set temperature of the floor heating device.

In the floor heating device according to the fifth aspect, after the transition from the start operation mode to another operation mode, the determination unit determines the temperature drop per unit period at the room temperature detected by the detection unit as a predetermined reference When the decrease width is exceeded, the heating unit is controlled to shift to the start operation mode.

For this reason, when the temperature drop per unit period in the room temperature detected by the detection unit exceeds a predetermined standard drop width, compared to the configuration in which the current operation mode is maintained, for example, ventilation by opening the window causes a sudden drop. Even when the temperature drops, the room temperature is prevented from dropping below the set temperature of the floor heating device.

In the floor heating device according to the sixth aspect, the heating unit further has a modest operation mode in which the amount of heating heat for heating the floor material is less than that in the steady operation mode, and the determination unit determines that the start Operation of the heating unit is started in an operation mode, and a temperature rise width when a predetermined reference time elapses from the start of operation of the heating unit at the room temperature detected by the detection unit is a predetermined reference. If it is equal to or greater than the increase range, the heating unit is controlled to shift from the start operation mode to the modest operation mode and then to the steady operation mode.

Therefore, when the temperature rise width is equal to or greater than the reference rise width, the room temperature is suppressed from rising beyond the set temperature of the floor heating device compared to the configuration in which the start operation mode is continued.

Since the present invention is configured as described above, in a floor heating apparatus including a heating unit that heats the floor material, it is used together with the floor heating apparatus when the heating unit is operated in the steady operation mode. It has an excellent effect of being able to grasp the operating conditions of other heating devices.

(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 and heats a 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 room 104 in which the floor heating device 10 is installed. The air conditioner 100 is attached to the side wall 109 of the 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. Further, as shown in FIG. 2, the air conditioner 100 is installed at a position where the distance L1 from the side wall 110 arranged on the side of the air conditioner 100 is, for example, about 1360 mm. A height HA (see FIG. 1) from the floor surface 106 of the room 104 to the ceiling 108 is, for example, 2400 mm. The size of the room 104 is, for example, 6370 mm (see symbol D1 in FIG. 2)×3640 mm (see symbol W1 in FIG. 2).

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 section 20 is a hot water type heating section, and includes, for example, a floor panel 22 , a heater 24 and a circulation pipe 26 .

The floor panel 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 circulates hot water as a heat medium between the floor panel 22 and the heater 24 . The heater 24 heats the hot water circulating in the circulation pipe 26 .

In the heating unit 20 , the hot water heated by the heater 24 circulates between the floor panel 22 and the heater 24 through the circulation pipe 26 to heat the floor material 102 .

The heater 24 can change the temperature for heating the hot water circulating in the circulation pipe 26 (hereinafter referred to as heating temperature) and the flow rate of the hot water in a plurality of steps. By changing the heating temperature and flow rate of the hot water in the heating unit 20, the amount of heat for heating the floor material 102 (hereinafter referred to as the amount of heat for heating) can be adjusted in multiple stages.

The amount of heat to be heated by the heating unit 20 (that is, the heating temperature and flow rate of hot water) is associated in advance with the set temperature input through the operation unit 30 . For example, each of heating heat amounts A, B, C, and D is associated with each of set temperatures a, b, c, and d. In this case, for example, the set temperatures a, b, c, and d are temperatures that increase in this order, and the heating heat amounts A, B, C, and D are heat amounts that increase in this order.

Furthermore, the heating unit 20 has a plurality of operation modes. Specifically, the heating section 20 has a plurality of operation modes, namely, a rapid heating operation mode, a steady operation mode, and a modest operation mode.

The steady operation mode is an operation mode that is executed during steady operation of the heating unit 20, and is an operation mode in which the amount of heating heat for heating the floor material 102 is smaller than that in the rapid heating operation mode. In the steady operation mode, the heating unit 20 heats the floor material 102 with the amount of heating heat associated with the set temperature input from the operation unit 30 . That is, the steady operation mode is a mode in which the heating unit 20 is operated with the set temperature as the target temperature.

The rapid heating operation mode is an operation mode in which the amount of heating heat for heating the flooring 102 is larger than that in the steady operation mode, and is an example of the start operation mode. In the rapid heating operation mode, the floor material 102 is heated with a heating heat amount higher than the heating heat amount associated with the set temperature input through the operation unit 30 . As a result, in the rapid heating operation mode, the floor material 102 is heated to a higher temperature than in the steady operation mode.

The moderate operation mode is an operation mode in which the amount of heat for heating the floor material 102 is less than that in the steady operation mode. In the modest operation mode, the floor material 102 is heated with an amount of heat for heating that is lower than the amount of heat for heating associated with the set temperature input through the operation unit 30 . As a result, the floor material 102 is heated to a lower temperature in the modest operation mode than in the steady operation mode.

In this way, the rapid heating operation mode, the steady operation mode, and the moderate operation mode are operation modes based on the set temperature input through the operation unit 30 . Furthermore, the heating unit 20 can stepwise decrease the heating heat amount for heating the floor material from the heating heat amount in the steady operation mode regardless of the set temperature input by the operation unit 30. .

(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 room 104 . Further, the operation unit 30 is installed at a position where the height H2 from the floor surface 106 is approximately 1100 mm, for example. Furthermore, as shown in FIG. 2, the operation unit 30 is installed at a position where the distance L2 from the side wall 110 arranged on the side of the air conditioner 100 is, for example, about 4000 mm.

(Room temperature sensor 40)
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 the 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 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 determination 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, a timer 64, and a counter 66, as shown in FIG.

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. 4) 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.

A timer 64 is a measuring unit for measuring a reference time, which will be described later. A counter 66 is a measuring unit for measuring a reference number of times, 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. 4 is a block diagram showing the functional configuration of the processor 61. As shown in FIG.

As shown in FIG. 4, in the control device 60, the processor 61 functions as an acquisition unit 61A and an operation control unit 61B 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 an operation instruction input by the user through the operation unit 30 and information on the set temperature (hereinafter referred to as set temperature information). Acquisition unit 61A also acquires, from room temperature sensor 40, room temperature information detected by room temperature sensor 40 (hereinafter referred to as room temperature information).

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

When the acquisition unit 61A acquires the operation instruction, the operation control unit 61B causes the heating unit 20 to start operating in the rapid heating operation mode.

Further, after the operation of the heating unit 20 is started, the operation control unit 61B determines that the temperature rise width when a predetermined first reference time has elapsed from the start of operation of the heating unit 20 at the room temperature detected by the room temperature sensor 40 is When the temperature is equal to or greater than a predetermined reference increase width, the heating unit 20 is controlled to shift from the rapid heating operation mode to the modest operation mode.

Note that the first reference time is, for example, 10 minutes. Also, the reference increase width is set within a range of 4 to 6° C., for example. The first reference time and the reference rise width are set in advance, and the information on the first reference time and the reference rise width is stored in the storage 63 . The elapsed time from the start of operation of the heating unit 20 is measured by the timer 64 .

Further, after the operation of the heating unit 20 is started, the operation control unit 61B determines in advance from the time when the first reference time elapses when the temperature rise width in the room temperature detected by the room temperature sensor 40 is less than the reference rise width. When the room temperature sensor 40 detects a room temperature equal to or higher than the set temperature after the second reference time has elapsed, the heating unit 20 is controlled to shift from the rapid heating operation mode to the moderate operation mode. Note that "after the second reference time has elapsed" is a concept that includes the point in time when the second reference time has elapsed.

Note that the second reference time is, for example, 10 minutes. That is, the second reference time and the first reference time are the same time. The second reference time is set in advance, and information on the second reference time is stored in the storage 63 . The elapsed time after the first reference time has elapsed is measured by the timer 64 .

Further, if the room temperature sensor 40 detects a room temperature lower than the set temperature after the second reference time has elapsed since the first reference time, the operation control unit 61B controls the second reference time from the second reference time. Every time the time elapses, it is determined whether the room temperature sensor 40 detects a room temperature equal to or higher than the set temperature, and when the room temperature sensor 40 detects a room temperature equal to or higher than the set temperature, control is performed to shift from the rapid heating operation mode to the modest operation mode. is performed on the heating unit 20 .

In other words, while the room temperature sensor 40 does not detect a room temperature equal to or higher than the set temperature and the room temperature sensor 40 detects a room temperature lower than the set temperature, the operation control unit 61B controls the heating unit 20 to maintain moderate operation. against

Further, the operation control unit 61B shifts to the steady operation mode when a predetermined reference elapsed time elapses after shifting from the rapid heating operation mode at the start of operation to the modest operation mode.

Note that the reference elapsed time is, for example, 30 minutes. The reference elapsed time is set in advance, and information on the reference elapsed time is stored in the storage 63 . The timer 64 measures the elapsed time after the rapid heating operation mode at the start of operation is shifted to the moderate operation mode.

Further, after the operation control unit 61B shifts to the steady operation mode, the room temperature sensor 40 detects the room temperature exceeding the set temperature, and then during a predetermined reference period (hereinafter, sometimes referred to as the reference period A) It is determined that the air conditioner 100 is operating when the room temperature exceeding the set temperature is detected for a predetermined reference number of times (hereinafter sometimes referred to as the reference number of times A). Further, when the operation control unit 61B determines that the air conditioner 100 is being operated, the operation control unit 61B controls the heating unit 20 to reduce the heating heat amount from the heating heat amount in the steady operation mode.

Note that the reference period A is, for example, one minute. The reference number of times A is, for example, 20 times. The reference period A and the reference number of times A are set in advance, and information on the reference period A and the reference number of times A is stored in the storage 63 . The elapsed time after the room temperature sensor 40 detects the room temperature exceeding the set temperature is measured by the timer 64 . A counter 66 counts the number of times the room temperature sensor 40 detects a room temperature exceeding the set temperature.

After the room temperature sensor 40 detects the room temperature exceeding the set temperature after the heating heat amount is reduced from the heating heat amount in the steady operation mode, the operation control unit 61B exceeds the set temperature a reference number of times A in the reference period A. When the room temperature is detected again, the heating unit 20 is controlled to decrease the amount of heating heat again.

In addition, after the room temperature sensor 40 detects a room temperature lower than the set temperature, the operation control unit 61B reduces the amount of heating heat, and then during a predetermined reference period (hereinafter sometimes referred to as a reference period B) When a room temperature lower than the set temperature is detected for a predetermined reference number of times (hereinafter sometimes referred to as reference number B), the heating unit 20 is controlled to restore the amount of heating heat.

Note that the reference period B is, for example, one minute. The reference number of times B is, for example, 20 times. The reference period B and the reference number of times B are set in advance, and information on the reference period B and the reference number of times B is stored in the storage 63 . The elapsed time after the room temperature sensor 40 detects the room temperature exceeding the set temperature is measured by the timer 64 . A counter 66 counts the number of times the room temperature sensor 40 detects a room temperature exceeding the set temperature.

In addition, when the temperature drop per unit period of the room temperature detected by the room temperature sensor 40 exceeds a predetermined reference range of drop after the rapid heating operation mode at the start of operation is shifted to the moderate operation mode, the operation control unit 61B Then, the heating unit 20 is controlled to shift to the rapid heating operation mode.

Note that the reference decrease width is, for example, −2.2° C./min. The reference drop width is set in advance, and information on the reference drop width is stored in the storage 63 .

In addition, after shifting to the rapid heating operation mode, the operation control unit 61B determines that the temperature rise width when a predetermined first reference time has passed since the transition to the rapid heating operation mode at the room temperature detected by the room temperature sensor 40 is , the heating unit 20 is controlled to shift from the rapid heating operation mode to the modest operation mode when the temperature is equal to or greater than a predetermined reference increase width.

The first reference time, the reference increase range, the second reference time, the reference elapsed time, the reference period A, the reference number of times A, the reference period B, the reference number of times B, the reference decrease range, etc. can be set by the user through the operation unit 30. It may be a configuration in which settings can be changed.

(Control processing according to the present embodiment)
Next, an example of control processing according to this embodiment will be described. In the present embodiment, as an example, an operation start control process that is executed when the floor heating device 10 is started, a steady operation control process that is executed when the floor heating device 10 is in steady operation, and an operation start control process. and a ventilation detection process that is executed separately from the steady operation control process.

FIG. 5 is a flowchart showing an example of the operation start control process executed by the control device 60. As shown in FIG. FIG. 6 is a flow chart showing an example of the steady-state operation control process executed by the control device 60. As shown in FIG. FIG. 7 is a flowchart showing an example of the flow of ventilation detection control processing executed by the control device 60. As shown in FIG.

The operation start control process, the steady operation control process, and the ventilation detection process are performed by the processor 61 reading out the control program 63A from the storage 63 and executing them cooperatively.

(Operation start control processing)
As an example, the operation start control process is started when the floor heating device 10 is turned on through the operation unit 30 . When the floor heating device 10 is turned on, for example, a desired room temperature is input through the operation unit 30 .

The processor 61 causes the heating unit 20 to start operating in the rapid heating operation mode, as shown in FIG. 5 (step S102).

Next, the processor 61 determines whether or not a first reference time (for example, 10 minutes) has elapsed since the operation of the heating unit 20 was started (step S104).

When the processor 61 determines that the first reference time has elapsed (step S104: YES), the process proceeds to step S106. On the other hand, when the processor 61 determines that the first reference time has not passed (step S104: NO), it performs step S104 again. That is, the processor 61 repeats step S104 until the first reference time elapses.

In step S106, the processor 61 determines that the temperature rise width when the first reference time (for example, 10 minutes) has elapsed since the start of operation of the heating unit 20 at the room temperature detected by the room temperature sensor 40 is the reference rise width (for example, 4 A temperature set in the range of ~6°C) or higher.

When the processor 61 determines that the temperature rise width is equal to or greater than the reference rise width (step S106: YES), the processor 61 determines that the air conditioner 100 is operating (step S108), and the heating unit 20 is operated. The mode is shifted from the rapid heating operation mode to the modest operation mode (step S110), and the process proceeds to step S116. It should be noted that the determination itself that the air conditioner 100 is in operation (step S108) does not need to be clearly indicated to the outside of the apparatus. Since the control in step S110 for shifting to the modest operation mode is performed on the assumption that the air conditioner 100 is in operation, as a result of performing the control in step S110, the operation mode of the heating unit 20 is changed from the rapid heating operation mode to the moderate operation mode, it can be considered that the air conditioner 100 is determined to be in operation.

On the other hand, when the processor 61 determines that the temperature rise width is less than the reference rise width (step S106: NO), the process proceeds to step S112. In step S112, it is determined whether or not a second reference time (for example, 10 minutes) has passed since the first reference time has elapsed.

When the processor 61 determines that the second reference time has elapsed (step S112: YES), the process proceeds to step S114. On the other hand, when the processor 61 determines that the second reference time has not passed (step S112: NO), it performs step S112 again. That is, the processor 61 repeats step S112 until the second reference time elapses.

In step S114, the processor 61 determines whether or not the room temperature sensor 40 has detected a room temperature equal to or higher than the set temperature.

When the processor 61 determines that the room temperature sensor 40 has detected a room temperature equal to or higher than the set temperature (step S114: YES), the processor 61 determines that the air conditioner 100 is operating (step S108), and the heating unit 20 is operated. The mode is shifted from the rapid heating operation mode to the modest operation mode (step S110), and the process proceeds to step S116.

On the other hand, when the processor 61 determines that the room temperature sensor 40 has detected a room temperature lower than the set temperature (step S114: NO), the process returns to step S112.

In step S116, the processor 61 determines whether or not a reference elapsed time (for example, 30 minutes) has elapsed from the time when the modest operation mode was entered.

When the processor 61 determines that the reference elapsed time has elapsed (step S116: YES), the processor 61 shifts the operation mode of the heating unit 20 from the moderate operation mode to the steady operation mode (step S118), and terminates this process. .

On the other hand, when the processor 61 determines that the reference elapsed time has not passed (step S116: NO), it performs step S116 again. That is, the processor 61 repeats step S116 until the reference elapsed time elapses.

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

(Regular operation control processing)
Execution of the steady operation control process is started after the heating unit 20 shifts to the steady operation mode and the operation start control process ends. Therefore, the steady operation control process is executed in series with the operation start control process, and when one of the steady operation control process and the operation start control process is being executed, the other is not executed.

Processor 61, as shown in FIG. 6, determines whether or not room temperature sensor 40 has detected a room temperature exceeding the set temperature (step S202). Specifically, the processor 61 determines, for example, whether or not a room temperature higher than the set temperature by 2.2° C. has been detected.

When the processor 61 determines that the room temperature sensor 40 has detected a room temperature exceeding the set temperature (step S202: YES), the process proceeds to step S204.

On the other hand, when the processor 61 determines that the room temperature sensor 40 has not detected a room temperature exceeding the set temperature (step S202: NO), the processor 61 performs step S202 again.

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

(Ventilation detection processing)
The ventilation detection process is, for example, a process for detecting a temperature drop caused by ventilation by opening a window or the like in a room in which the floor heating device 10 is installed, and for controlling the operation mode of the heating unit 20 . Execution of the ventilation detection process is started, for example, when the heating unit 20 shifts to the moderate operation mode (step S110), and is executed in parallel with one of the operation start control process and the steady operation control process.

Processor 61, as shown in FIG. 7, determines whether or not the temperature drop per unit period of the room temperature detected by room temperature sensor 40 exceeds a predetermined reference range of drop (step S302). Specifically, in step S302, the processor 61 determines whether or not the room temperature sensor 40 detects a room temperature of -2.2°C/min, for example.

If the temperature drop per unit period in the room temperature detected by the room temperature sensor 40 exceeds a predetermined reference drop width (step S302: YES), the processor 61 performs operation start control that is executed in parallel with the ventilation detection process. In the process or steady-state operation control process, the operation mode of the heating unit 20 is shifted to the rapid heating operation mode in step S102 (step S304). That is, the processor 61 returns to step S102 when executing the operation start control process in parallel with the ventilation detection process. If the processor 61 is executing the steady-state operation control process in parallel with the ventilation detection process, the processor 61 ends execution of the steady-state operation control process and starts execution of the operation start control process. After executing step S302, the processor 61 ends this process.

If the temperature drop per unit period of the room temperature detected by the room temperature sensor 40 does not exceed the predetermined reference drop width (step S302: NO), the processor 61 performs step S302 again. That is, the processor 61 repeats step S302 until the temperature drop per unit period in the room temperature detected by the room temperature sensor 40 exceeds a predetermined reference drop width.

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

(Effects of this embodiment)
As described above, in the floor heating device 10 according to the present embodiment, after the processor 61 shifts the operation mode of the heating unit 20 to the steady operation mode, the room temperature sensor 40 detects the room temperature exceeding the set temperature. After that, when the room temperature exceeding the set temperature is detected a predetermined reference number of times in a predetermined reference period, it is determined that the air conditioner 100 is operating. (Step S202: YES, Step S204: YES, Step S206: YES, see S208).

Therefore, when the heating unit 20 is operated in the steady operation mode, the operation status of the air conditioner 100 used together with the floor heating device 10 can be grasped.

In the floor heating device 10, the processor 61 controls the heating unit 20 to reduce the heating heat amount from the heating heat amount in the steady operation mode when determining that the air conditioner 100 is being operated. (See steps S210 and S222).

Therefore, when it is determined that the air conditioner 100 is operating, the room temperature is prevented from rising beyond the set temperature of the floor heating device 10 compared to a configuration in which the rapid heating operation mode is continued.

Further, in the floor heating device 10, the processor 61 reduces the heating heat amount from the heating heat amount in the steady operation mode, and after the room temperature sensor 40 detects the room temperature exceeding the set temperature, the reference number of times in the reference period, When the room temperature exceeding the set temperature is detected again, the heating unit 20 is controlled to decrease the amount of heating heat again (step S214: YES, step S216: YES, step S218: YES, see S220 and S222). .

Therefore, after the room temperature sensor 40 detects a room temperature exceeding the set temperature, if the determination of whether or not the room temperature exceeds the set temperature the reference number of times in the reference period is affirmative, the heating of the heating unit 20 is performed. As compared with the configuration that maintains the amount of heat, the room temperature is suppressed from rising beyond the set temperature of the floor heating device 10 .

Further, in the floor heating device 10, the processor 61 reduces the heating heat amount from the heating heat amount in the steady operation mode, and after the room temperature sensor 40 detects the room temperature below the set temperature, the reference number of times in the reference period, When a room temperature lower than the set temperature is detected, the heating unit 20 is controlled to restore the amount of heating heat (step S240: YES, step S242: YES, step S244: YES, see S246).

Therefore, when the room temperature sensor 40 detects a room temperature lower than the set temperature and then detects a room temperature lower than the set temperature a reference number of times in the reference period, the heating heat amount is kept reduced. Even when the operation of the air conditioner 100 that has been operated together with the floor heating device 10 is stopped, the room temperature is prevented from falling below the set temperature of the floor heating device 10 .

In the floor heating device 10, the processor 61 determines that the temperature drop per unit period of the room temperature detected by the room temperature sensor 40 after shifting from the rapid heating operation mode at the start of operation to the moderate operation mode is a predetermined reference drop. If the range is exceeded, the heating unit 20 is controlled to shift to the rapid heating operation mode (step S302: YES, see step S304).

For this reason, when the temperature drop per unit period of the room temperature detected by the room temperature sensor 40 exceeds a predetermined reference drop range, compared to a configuration in which the current operation mode is maintained, for example, ventilation by opening a window etc. Even if the temperature drops significantly, the room temperature is prevented from dropping below the set temperature of the floor heating device 10 .

Further, in the floor heating device 10, the processor 61 calculates the temperature at the room temperature detected by the room temperature sensor 40 after a predetermined first reference time has elapsed from the start of operation of the heating unit 20 after the operation of the heating unit 20 is started. When the increase width is equal to or greater than the predetermined reference increase width, control is performed on the heating unit 20 to shift from the rapid heating operation mode to the moderate operation mode (step S104: YES, step S106: YES, S108 , S110).

Therefore, when the temperature rise range is equal to or greater than the reference rise range, the room temperature is prevented from rising beyond the set temperature of the floor heating device 10 compared to the configuration in which the rapid heating operation mode is continued.

In a modification of the steady-state operation control process, as shown in FIG. 8, in step S224, the processor 61 determines whether or not the amount of heating heat of the heating unit 20 is the minimum amount of heat. The minimum amount of heat is the lowest amount of heat for heating that can be used in the heating unit 20 .

When the processor 61 determines that the amount of heating heat of the heating unit 20 is the minimum amount of heat (step S224: YES), the process proceeds to step S402.

On the other hand, when the processor 61 determines that the amount of heating heat of the heating unit 20 is not the minimum amount of heat (step S224: NO), the process returns to step S212.

In step S402, the processor 61 determines whether or not a reference elapsed time (for example, 30 minutes) has elapsed since the amount of heating heat was reduced to the minimum amount of heat.

When the processor 61 determines that the reference elapsed time has elapsed (step S402: YES), the process proceeds to step S404.

On the other hand, when the processor 61 determines that the reference elapsed time has not elapsed (step S402: NO), it performs step S402 again. That is, the processor 61 repeats step S402 until the reference elapsed time elapses.

In step S404, the processor 61 determines whether or not the temperature drop per unit period in the room temperature detected by the room temperature sensor 40 exceeds a predetermined reference drop width. Specifically, in step S3404, the processor 61 determines whether or not the room temperature sensor 40 detects a room temperature of -2.2°C/min, for example.

If the temperature drop per unit period in the room temperature detected by the room temperature sensor 40 exceeds a predetermined reference drop width (step S404: YES), the processor 61 increases the amount of heating heat of the heating unit 20 ( step S406) and returns to step S402. In step S406, the processor 61 increases the amount of heating heat of the heating unit 20 by one step, for example. More specifically, the processor 61 increases, at step S406, for example, the amount that was decreased at step S222.

On the other hand, processor 61 returns to step S224 when the temperature drop per unit period of the room temperature detected by room temperature sensor 40 does not exceed the predetermined reference drop width (step S404: NO).
