Description

The present disclosure relates to heating systems and heaters.

Conventionally, a bathroom heater for heating a bathroom is known (see Patent Document 1). Further, in recent years, from the viewpoint of reducing heat shock, it has been proposed to install a heater in a washroom or a dressing room adjacent to the bathroom.

Japanese Patent Application Laid-Open No. 2003-222348

Electric heaters are used for heaters for bathrooms and adjacent rooms. However, some electric heaters generate an inrush current immediately after energization, and if the heaters for the bathroom and the adjacent room are operated in conjunction with each other, the timing of the inrush current generation may overlap and an excessive current may be generated. be.

As a method of avoiding the generation of an excessive current, for example, it is conceivable to shift the generation timing of the inrush current by delaying the operation start timing of one of the heaters at the start of the interlocking operation. However, if the operation start timing is delayed, the user may feel uncomfortable, for example, the user may mistakenly recognize the failure.

The present disclosure provides a technique capable of suppressing the generation of an excessive current when two heaters are operated in conjunction with each other without giving a sense of discomfort to the user.

The heating system according to an embodiment of the present disclosure includes a first heater including a fan and an electric heater, a second heater including a fan and an electric heater, the first heater and the second heating. The control unit includes a control unit for controlling the machine, and the control unit drives the fan and the heater in a first mode, and drives the fan, and the output of the heater is higher than the output of the heater in the first mode. When performing interlocking operation in which both the first heater and the second heater are operated, the heater of one of the first heater and the second heater has a lower second mode. In the first mode, and the other heater of the first heater and the second heater is operated in the second mode, and then the operation mode of the other heater is set to the first mode. The mode shifts from the second mode to the first mode.

In the case of interlocking operation, by operating one heater in the first mode and operating the other heater in the second mode, the timing of inrush current generation in the two heaters can be staggered. As a result, it is possible to avoid the generation of an excessive current due to the overlap of the generation timings of the inrush currents. On the other hand, since the fan of the other heater starts operating without delay, there is no risk of misleading the user to a failure or the like. Therefore, it is possible to suppress the generation of an excessive current when the two heaters are operated in conjunction with each other without giving a sense of discomfort to the user.

Further, the second mode is a mode for driving only the fan among the fan and the heater.

By not driving the heater in the second mode, the timing of inrush current generation in the two heaters can be staggered.

Further, in the second mode, the control unit drives the fan at a rotation speed lower than the rotation speed of the fan in the first mode.

As a result, it is possible to suppress power consumption and noise in the second mode. In addition, it is possible to suppress the blowing of cold air from the second heater in the second mode.

Further, at least one of the first heater and the second heater includes a temperature detection unit, and the control unit determines the duration of the second mode based on the detection result of the temperature detection unit.

The lower the temperature in the room, the more power is required to heat the room to the desired temperature. In other words, it takes a long time for the inrush current to subside. Therefore, by determining the duration of the second mode based on the detection result of the temperature detection unit, it is possible to more reliably suppress the generation of an excessive current.

Further, the control unit determines the duration of the second mode based on the power consumption value of at least the heater driven in the first mode among the first heater and the second heater.

By determining the duration of the second mode based on the power consumption value of at least the heater driven in the first mode among the first heater and the second heater, the delay is suppressed while suppressing the generation of excessive current. It is possible to start energizing the heater on the side of the heating as soon as possible.

Further, the control unit has the first heater within a predetermined grace period after the instruction of the first independent operation for operating one of the first heater and the second heater. And when the second independent operation to operate the other heater of the second heater is instructed, the one heater or the other heater is operated in the second mode.

As a result, even when the first independent operation and the second independent operation are individually instructed, it is possible to avoid the generation of an excessive current due to the overlap of the inrush current generation timings.

Further, the first heater and the second heater include a temperature detection unit, and the control unit is instructed to perform the second independent operation within the grace period after the instruction to perform the first independent operation. In this case, the heater having the lower temperature detected by the temperature detection unit among the one heater and the other heater is operated in the first mode, and the temperature detected by the temperature detection unit is operated. The heater with the higher value is operated in the second mode.

As a result, it is possible to preferentially heat the room in which the temperature is lower than the room in which the first heater is installed and the room in which the second heater is installed.

Further, the control unit includes a notification unit for notifying that the interlocking operation is in progress, and the control unit is described when the second independent operation is instructed within the grace period after the first independent operation is instructed. Notify the notification unit that the interlocking operation is in progress.

As a result, even when the first independent operation and the second independent operation are individually instructed, it is possible to notify the user that the interlocking operation is in progress, and the usability can be improved.

Further, the heater according to the embodiment of the present disclosure includes a fan, an electric heater, and a control unit for controlling the fan and the heater, and the control unit drives the fan and the heater. When it has a first mode and a second mode in which the output of the heater is lower than the output of the heater in the first mode while driving the fan, and interlocking operation with another heater is performed. It can be operated in the second mode.

In the case of interlocking operation, by operating the heater according to the embodiment of the present disclosure in the second mode, it is possible to shift the generation timing of the inrush current in the two heaters. As a result, it is possible to avoid the generation of an excessive current due to the overlap of the generation timings of the inrush currents. On the other hand, since the operation of the fan is started without delay, there is no risk of misleading the user to a failure or the like. Therefore, it is possible to suppress the generation of an excessive current when the two heaters are operated in conjunction with each other without giving a sense of discomfort to the user.

According to the present disclosure, it is possible to suppress the generation of an excessive current when the two heaters are operated in conjunction with each other without giving a sense of discomfort to the user.

FIG. 2 is a block diagram showing a configuration example of the heating system 1 according to the embodiment of the present disclosure. As shown in FIG. 2, the first heater 10 includes a fan 11, a heater 12, and a temperature detecting unit 13.

The fan 11 is arranged in the air passage of the first heater 10. The air passage of the first heater 10 is, for example, a duct that communicates the suction port and the air outlet that open toward the inside of the bathroom 2, and the fan 11 generates an air flow from the suction port to the air outlet. Let me. The fan 11 is configured to include a drive unit such as a motor, and is controlled by the control device 40.

The heater 12 is an electric heater that generates heat by energization, and heats by energization. The on / off of the energization of the heater 12 is controlled by the control device 40.

The temperature detection unit 13 detects the temperature of the bathroom 2. For example, the temperature detection unit 13 is arranged in the air passage of the first heater 10 and detects the temperature in the air passage of the first heater 10. The temperature detection unit 13 outputs the temperature detection result of the bathroom 2 to the control device 40.

The second heater 20 includes a fan 21, a heater 22, and a temperature detecting unit 23. The fan 21 is arranged in the housing of the second heater 20, sucks air into the housing from a suction port formed in the housing, and sends the sucked air toward the air outlet formed in the housing. The fan 21 is configured to include a drive unit such as a motor, and is controlled by the control device 40.

The heater 22 is arranged in the housing of the second heater 20 and heats the air flowing toward the air outlet. The heater 22 is an electric heater that generates heat by energization, and heats by energization. The on / off of the energization of the heater 22 is controlled by the control device 40.

The temperature detection unit 23 detects the temperature of the adjacent room 3. For example, the temperature detection unit 23 is arranged in the housing of the second heater 20. The temperature detection unit 23 outputs the temperature detection result of the adjacent room 3 to the control device 40.

The operation unit 30 includes a bathroom operation button 31, an adjacent room operation button 32, an interlocking operation button 33, a communication unit 34, a bathroom operation light emitting unit 35, an adjacent room operation light emitting unit 36, and an interlocking operation light emitting unit 37. .. The bathroom operation light emitting unit 35, the adjacent room operation light emitting unit 36, and the interlocking operation light emitting unit 37 are, for example, LED lamps.

When the bathroom operation button 31 is operated, the operation unit 30 causes the bathroom operation light emitting unit 35 to emit light, and transmits an operation signal to the effect that the bathroom operation button 31 is operated to the control device 40 via the communication unit 34. do. Further, when the adjacent room operation button 32 is operated, the operation unit 30 causes the adjacent room operation light emitting unit 36 to emit light, and the operation signal to the effect that the adjacent room operation button 32 is operated is transmitted to the control device 40 via the communication unit 34. Send to. Further, when the interlocking operation button 33 is operated, the operation unit 30 causes the interlocking operation light emitting unit 37 to emit light, and the operation signal to the effect that the interlocking operation button 33 is operated is transmitted to the control device 40 via the communication unit 34. Send to.

The control device 40 includes a control unit 41 and a storage unit 42. The storage unit 42 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory (Flash Memory).

The control unit 41 is realized by executing a program stored in the storage unit 42 with a RAM as a work area by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like. Further, the control unit 41 is realized by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

The control unit 41 includes an operation control unit 43, a priority determination unit 44, and a duration determination unit 45, and realizes or executes a function or operation described below. The internal configuration of the control unit 41 is not limited to the configuration shown in FIG. 2, and may be another configuration.

The operation control unit 43 controls the operation of the first heater 10 and the second heater 20. Specifically, when the operation control unit 43 receives an operation signal indicating that the bathroom operation button 31 has been operated from the operation unit 30, the operation control unit 43 drives the fan 11 and the heater 12 of the first heater 10. 1 The heating operation by the heater 10 (hereinafter referred to as "first independent operation") is started. Further, when the operation control unit 43 receives an operation signal indicating that the adjacent room operation button 32 has been operated from the operation unit 30, the operation control unit 43 drives the fan 21 and the heater 22 of the second heater 20 to drive the second heater 20. (Hereinafter referred to as "second independent operation") is started.

Further, when the operation control unit 43 receives an operation signal indicating that the interlocking operation button 33 has been operated from the operation unit 30, the operation unit 43 has the fan 11 and the heater 12 of the first heater 10 and the fan 21 of the second heater 20. By driving the heater 22 and the heater 22, a heating operation (hereinafter, referred to as “interlocking operation”) is performed by the first heater 10 and the second heater 20.

Here, the heaters 12 and 22 are PTC (Positive Temperature Coefficient) heaters. The PTC heater has a characteristic that the resistance value changes depending on the temperature, and the self-temperature can be controlled by repeatedly increasing and decreasing the resistance value.

However, due to its characteristics, the PTC heater has a problem that an inrush current is generated immediately after the start of energization. The inrush current is a large current that flows temporarily. Therefore, in the case of interlocking operation, if the heater 12 of the first heater 10 and the heater 22 of the second heater 20 are energized at the same timing, the inrush current generation timings overlap, for example, the capacity of the breaker. There is a risk that the breaker will trip due to an excessive current exceeding the above.

As a method of avoiding the generation of an excessive current, for example, it is conceivable to shift the generation timing of the inrush current by delaying the operation start timing of one of the heaters at the start of the interlocking operation. However, if the operation start timing is delayed, the user may feel uncomfortable, for example, the user may mistakenly recognize the failure.

Therefore, the operation control unit 43 has a first mode and a second mode as operation control modes of the first heater 10 and the second heater 20. The first mode is a mode for driving a fan and a heater (fan 11 and heater 12 or fan 21 and heater 22). The second mode is a mode in which the output of the heater (heater 12 or heater 22) is lower than the output of the heater (heater 12 or heater 22) in the first mode while driving the fan (fan 11 or fan 21). Specifically, the second mode is a mode in which only the fan (fan 11 or fan 21) of the fans and heaters (fan 11 and heater 12 or fan 21 and heater 22) is driven.

When performing interlocking operation, the operation control unit 43 operates one of the first heater 10 and the second heater 20 in the first mode, and operates the other heater in the second mode. Let me. After that, the operation control unit 43 shifts the operation mode of the other heater from the second mode to the first mode. As a result, it is possible to suppress the generation of an excessive current when the first heater 10 and the second heater 20 are operated in conjunction with each other without giving a sense of discomfort to the user.

This point will be described with reference to FIG. FIG. 3 is a timing chart showing an example of the start processing of the interlocking operation in the heating system 1.

As shown in FIG. 3, when the interlocking operation button 33 is operated (interlocking operation button ON), the operation control unit 43 causes, for example, the first heater 10 to operate in the first mode and the second heater 20 to operate. Operate in the second mode. That is, for the first heater 10, both the fan 11 and the heater 12 are driven (fan ON, heater ON), and for the second heater 20, only the fan 21 of the fan 21 and the heater 22 is driven. (Fan ON, heater OFF). After that, the operation control unit 43 shifts the operation mode of the second heater 20 from the second mode to the first mode by driving the heater 22 of the second heater 20 (fan ON, heater ON).

As described above, when the operation control unit 43 performs the interlocking operation, one of the first heater 10 and the second heater 20 is operated in the first mode, and the other heater is operated in the second mode. It is possible to shift the generation timing of the inrush current in the first heater 10 and the second heater 20 by operating the first heater 10 and the second heater 20. Therefore, it is possible to avoid the generation of an excessive current due to the overlap of the inrush current generation timings.

On the other hand, since the operation of the fan 21 of the second heater 20 is started without delay, there is no risk of misleading the user to a failure or the like. As described above, according to the operation control unit 43, it is possible to suppress the generation of an excessive current when the first heater 10 and the second heater 20 are operated in conjunction with each other without giving a sense of discomfort to the user.

For example, when the second heater 20 is operated in the second mode, the operation control unit 43 may drive the fan 21 at a rotation speed lower than the rotation speed of the fan 21 in the first mode. That is, the operation control unit 43 may rotate the fan 21 at a low speed in the second mode, and may rotate the fan 21 at a normal rotation speed when the mode shifts to the first mode. As a result, it is possible to suppress power consumption and noise in the second mode. Further, it is possible to suppress the blowing of cold air from the second heater 20 in the second mode.

Returning to FIG. 2, the priority determination unit 44 will be described. The priority determination unit 44 determines the heater (hereinafter, referred to as “priority heater”) to be operated in the first mode first among the first heater 10 and the second heater 20. Specifically, when the priority determination unit 44 receives an operation signal indicating that the interlocking operation button 33 has been operated from the operation unit 30, the detection result by the temperature detection unit 13 of the first heater 10 and the second heating The detection result by the temperature detection unit 23 of the machine 20 is acquired. Then, the priority determination unit 44 determines the heater having the lower detection result by the temperature detection units 13 and 23 among the first heater 10 and the second heater 20 as the priority heater.

For example, when the temperature of the bathroom 2 is lower than that of the bathroom 2 and the adjacent room 3, the priority determination unit 44 causes the first heater 10 installed in the bathroom 2 to be operated in the first mode first. Further, when the temperature of the adjacent room 3 is lower than that of the bathroom 2 and the adjacent room 3, the priority determination unit 44 causes the second heater 20 installed in the adjacent room 3 to be operated in the first mode first. As a result, the room having a lower temperature among the bathroom 2 and the adjacent room 3 can be preferentially heated.

Since the user enters the bathroom 2 and the adjacent room 3 first from the adjacent room 3, the priority determination unit 44 may determine the second heater 20 installed in the adjacent room 3 as the priority heater. ..

The duration determination unit 45 performs a process of determining the duration of the second mode. Specifically, the duration determination unit 45 of the second mode is based on the detection result of either one or both of the temperature detection unit 13 of the first heater 10 and the temperature detection unit 23 of the second heater 20. Determine the duration.

The lower the temperature of the bathroom 2 or the adjacent room 3, the more power is required to heat the bathroom 2 or the adjacent room 3 to a desired temperature. In other words, it takes a long time for the inrush current to subside. Therefore, the duration determination unit 45 lengthens the duration of the second mode as the temperature of the bathroom 2 or the adjacent room 3 becomes lower. As a result, the generation of excessive current can be suppressed more reliably.

For example, the storage unit 42 stores the duration information in which the temperature is associated with the duration of the second mode. The duration determination unit 45 uses a detection result having a lower temperature among the detection results by the temperature detection unit 13 and the detection result by the temperature detection unit 23, and stores the duration corresponding to the temperature indicated by the detection result in the storage unit 42. Determined by referring to the duration information stored in.

Not limited to the above example, the duration determination unit 45 may determine the duration using the average value of the detection result by the temperature detection unit 13 and the detection result by the temperature detection unit 23. Further, the duration determination unit 45 is a temperature detection unit (temperature detection unit 13 or temperature detection unit 23) of the heater (first heater 10 or second heater 20) determined as the priority heater by the priority determination unit 44. ) May be used to determine the duration. Further, the duration determination unit 45 may determine the duration using the detection result of one of the temperature detection unit 13 and the temperature detection unit 23, which is preset.

The duration determination unit 45 is not limited to the temperature of the bathroom 2 or the adjacent room 3, but is second based on the power consumption value of the heater driven in at least the first mode among the first heater 10 and the second heater 20. The duration of the mode may be determined.

For example, the duration determination unit 45 determines the power consumption value of the first heater 10 during the heating operation based on the monitoring results of the power consumption monitoring unit (not shown) provided in the first heater 10 and the second heater 20. The time-dependent change and the time-dependent change value of the power consumption during the heating operation of the second heater 20 are acquired. Further, in the duration determination unit 45, the total value of the power consumption of the first heater 10 and the second heater 20 is calculated based on the time-dependent changes in the power consumption of the first heater 10 and the second heater 20 acquired. , Calculate the delay time required to be equal to or less than the threshold power based on the capacity of the breaker. Then, the duration determination unit 45 determines the calculated delay time as the duration of the second mode.

Further, the duration determination unit 45 is, for example, based on the timing when the power consumption value of the heater driven in the first mode among the first heater 10 and the second heater 20 decreases, the second mode. It is also possible to determine the duration of.

As a result, it is possible to start energization of the heaters 12 and 22 on the delayed side as soon as possible while suppressing the generation of an excessive current. The change over time in the power consumption of the first heater 10 and the second heater 20 may be stored in advance.

Next, the procedure of the start processing of the interlocking operation in the heating system 1 will be described with reference to FIG. FIG. 4 is a flowchart showing an example of the procedure for starting the interlocking operation in the heating system 1.

As shown in FIG. 4, the control unit 41 determines whether or not the interlocking operation button 33 has been operated (step S101). This determination is made based on whether or not an operation signal indicating that the interlocking operation button 33 has been operated has been received from the operation unit 30. The control unit 41 repeats the determination process in step S101 until the interlocking operation button 33 is operated (steps S101 and No).

When it is determined in step S101 that the interlocking operation button 33 has been operated (steps S101, Yes), the control unit 41 first determines the priority heater to be operated in the first mode (step S102). For example, the control unit 41 determines the heater (first heater 10 or second heater 20) having a lower detection result by the temperature detection units 13 and 23 as the priority heater.

Subsequently, the control unit 41 determines the duration of the second mode (step S103). For example, the control unit 41 lengthens the duration of the second mode as the detection result by the temperature detection unit 13 or the temperature detection unit 23 is lower, that is, the lower the temperature in the bathroom 2 or the adjacent room 3.

Here, an example is shown in which the duration of the second mode is determined (step S103) after the priority heater is determined (step S102), but the order of steps S102 and S103 is reversed. You may.

Subsequently, the control unit 41 drives the fan and heater (fan 11 and heater 12 or fan 21 and heater 22) of the priority heater (step S104). Further, the control unit 41 drives a fan (fan 11 or fan 21) of the heater that is not prioritized (step S105). Further, the control unit 41 causes the interlocking operation light emitting unit 37 of the operation unit 30 to emit light (step S106).

Subsequently, the control unit 41 determines whether or not the duration of the second mode determined in step S103 has elapsed after driving the fan (fan 11 or fan 21) of the heater that is not prioritized in step S105. (Step S107). The control unit 41 repeats the determination process in step S107 until the duration of the second mode elapses (steps S107, No).

On the other hand, when it is determined in step S107 that the duration of the second mode has elapsed (steps S107, Yes), the control unit 41 drives the heater (heater 12 or heater 22) of the non-priority heater (step S108). ). That is, the operation mode of the non-priority heater is changed from the second mode to the first mode, and the start processing of the interlocking operation is ended. The control unit 41 stops the fans 11 and 21 and the heaters 12 and 22 of the first heater 10 and the second heater 20 and ends the interlocking operation, for example, when the preset operation time has elapsed. ..

Next, a modified example of the heating system 1 described above will be described. In the above-described embodiment, the interlocking operation is started when the interlocking operation button 33 of the operation unit 30 is operated. Not limited to this, the control unit 41 performs interlocking operation when the adjacent room operation button 32 is operated within a predetermined period (hereinafter, referred to as “grace period”) after the bathroom operation button 31 is operated. May start.

The processing procedure in this case will be described with reference to FIG. FIG. 5 is a flowchart showing an example of the procedure of the start processing of the interlocking operation according to the first modification.

As shown in FIG. 5, the control unit 41 determines whether or not the bathroom operation button 31 or the adjacent room operation button 32 has been operated (step S201). This determination is made based on whether or not an operation signal indicating that the bathroom operation button 31 has been operated or an operation signal indicating that the adjacent room operation button 32 has been operated has been received from the operation unit 30. The control unit 41 repeats the determination process in step S201 until the bathroom operation button 31 or the adjacent room operation button 32 is operated (steps S201, No).

When it is determined in step S201 that the bathroom operation button 31 or the adjacent room operation button 32 has been operated (step S201, Yes), the control unit 41 determines that the fan and heater (fan 11 and heater 12 or fan 21 and fan 21) of the corresponding heater. The heater 22) is driven (step S202). That is, the control unit 41 operates the corresponding heater in the first mode. Further, the control unit 41 causes the corresponding light emitting unit (bathroom operation light emitting unit 35 or adjacent room operation light emitting unit 36) to emit light (step S203).

For example, when it is determined that the bathroom operation button 31 has been operated, the control unit 41 drives the fan 11 and the heater 12 of the first heater 10 in step S202, and causes the bathroom operation light emitting unit 35 to emit light in step S203. When it is determined that the adjacent room operation button 32 has been operated, the control unit 41 drives the fan 21 and the heater 22 of the second heater 20 in step S202, and causes the adjacent room operation light emitting unit 36 to emit light in step S203.

Subsequently, the control unit 41 determines whether or not the other button, that is, the bathroom operation button 31 and the adjacent room operation button 32, which was not operated in step S201, was operated within the grace period ( Step S204). The control unit 41 repeats the determination process in step S204 until the other button is operated within the grace period (steps S204, No).

If it is determined in step S204 that the other button has been operated within the grace period (step S204, Yes), the control unit 41 determines the priority heater (step S205). Further, the control unit 41 determines the duration of the second mode (step S206).

Subsequently, the control unit 41 determines whether or not to give priority to the heater that is already in operation, that is, the heater that has started driving the fan and the heater in step S202 (step S207). For example, when the fan 11 and the heater 12 of the first heater 10 are driven in step S202, the control unit 41 determines whether or not the first heater 10 is determined as the priority heater in step S207.

In this determination, when it is determined to give priority to the heater that is already in operation (step S207, Yes), the control unit 41 drives the fan (fan 11 or fan 21) of the other heater (step S208). Further, the control unit 41 turns off the light emitting unit (bathroom operation light emitting unit 35 or the adjacent room operation light emitting unit 36) that was turned on in step S203, and turns on the interlocking operation light emitting unit 37 (step S209).

For example, when the heater already in operation is the first heater 10 and the first heater 10 is determined as the priority heater, that is, the first heater 10 which is the priority heater is already in the first mode. When the operation is started, the control unit 41 drives only the fan 21 of the fan 21 and the heater 22 of the second heater 20. That is, the control unit 41 operates the second heater 20 in the second mode. Then, the control unit 41 turns off the bathroom operation light emitting unit 35 and causes the interlocking operation light emitting unit 37 to emit light.

On the other hand, when the heater (step S207, No) that is already in operation is not prioritized in step S207, the control unit 41 stops the heater (heater 12 or heater 22) of the heater that is already in operation (step S210). .. Further, the control unit 41 drives the fan and heater (fan 11 and heater 12 or fan 21 and heater 22) of the other heater (step S211). Further, the control unit 41 turns off the light emitting unit (bathroom operation light emitting unit 35 or the adjacent room operation light emitting unit 36) that was turned on in step S203, and turns on the interlocking operation light emitting unit 37 (step S212).

When the process of step S209 or step S212 is completed, the control unit 41 determines whether or not the duration of the second mode has elapsed (step S213). The control unit 41 repeats the determination process of step S213 until the duration of the second mode elapses (steps S213 and No).

On the other hand, when it is determined in step S213 that the duration of the second mode has elapsed (steps S213, Yes), the control unit 41 drives the heater (heater 12 or heater 22) of the non-priority heater (step S214). ). That is, the operation mode of the non-priority heater is changed from the second mode to the first mode, and the start processing of the interlocking operation is ended.

As described above, for example, the control unit 41 may perform the second independent operation of operating the second heater 20 within a predetermined grace period after the instruction of the first independent operation of operating the first heater 10.

Further, when the second independent operation is instructed within the grace period after the first independent operation is instructed, the control unit 41 has the temperature detection unit 13 among the first heater 10 and the second heater 20. The heater with the lower temperature detected by the 23 is operated in the first mode, and the heater with the higher temperature detected by the temperature detection units 13 and 23 is operated in the second mode. As a result, the room in which the first heater 10 is installed and the room in which the second heater 20 is installed, whichever has a lower air temperature, can be preferentially heated.

Further, the heating system 1 includes an interlocking operation light emitting unit 37 (an example of an interlocking operation unit) for notifying that the interlocking operation is in progress. Then, when the second independent operation is instructed within the grace period after the first independent operation is instructed, the control unit 41 causes the interlocking operation light emitting unit 37 to emit light to the interlocking operation light emitting unit 37. Notify that the interlocking operation is in progress. As a result, even when the bathroom operation button 31 and the adjacent room operation button 32 are operated independently, it is possible to notify the user that the interlocking operation is in progress, and the usability can be improved.

Here, of the first heater 10 and the second heater 20, the case where only the first heater 10 is operated is referred to as “first independent operation”, and the case where only the second heater 20 is operated is “1st independent operation”. "Second independent operation". However, the present invention is not limited to this, and the case where only the second heater 20 is operated may be referred to as "first independent operation", and the case where only the first heater 10 is operated may be referred to as "second independent operation".
