Next, the operation and operation of the two-chamber heating system according to the first embodiment of the present invention will be described with reference to FIGS. 6 and 7.

FIG. 6 is a flowchart showing the control of the two-chamber heating system according to the first embodiment of the present invention. FIG. 7 is a graph showing an example of temperature transition between the bathroom temperature and the washroom temperature of the two-chamber heating system according to the first embodiment of the present invention.

As shown in FIG. 6, when the two-room heating for heating the bathroom 2 and the washroom 3 is started by the operation of the operation unit 8 by the user, the time set by the timer, or the like (step S100), The first temperature adjusting unit 152 of the bathroom heating device 100 calculates the first difference temperature ΔT1 which is the temperature difference between the temperature of the bathroom 2 and the target temperature when the two-room heating operation is performed (step S101). Specifically, the first difference temperature ΔT1 is calculated based on the temperature information of the bathroom 2 from the bathroom temperature sensor 107 and the target temperature information from the bathroom communication control unit 151.
Then, when the first difference temperature ΔT1 is larger than the predetermined temperature (absolute value: 10 ° C. in the present embodiment), the process proceeds to step S103, and in other cases, the process proceeds to step S102.
That is, it is determined which of ΔTa and ΔTb, which will be described later, is stored as the temperature rise value, depending on the magnitude of the difference temperature ΔT.
Here, also in the washroom heating device 200, the second temperature adjusting unit 252 calculates the second difference temperature ΔT2, which is the temperature difference between the temperature of the washroom 3 and the target temperature when heating the two rooms. Then, when the second difference temperature ΔT2 is larger than (10 ° C. in the present embodiment), the process proceeds to step S103, and in other cases, the process proceeds to step S102. As described above, in the first embodiment of the present invention, the washroom heating device 200 also performs the operations of steps S100 to S113.

When proceeding to step S102, the calculated difference temperature ΔT divided into Na is set as ΔTa and stored as the temperature rise value. Specifically, in the first temperature adjusting unit 152 (second temperature adjusting unit 252), the divided temperature ΔTa obtained by dividing the calculated first difference temperature ΔT1 into Na is stored as the temperature rise value.
On the other hand, when proceeding to step S103, the calculated difference temperature ΔT divided by Nb is set as ΔTb and stored as the temperature rise value. Similar to the case of ΔTa, the first temperature adjusting unit 152 (second temperature adjusting unit 252) stores the divided temperature ΔTb obtained by dividing the calculated first difference temperature ΔT1 into Nb as the temperature rise value.
In the case of the washroom heating device 200, the second temperature adjusting unit 252 sets the calculated second difference temperature ΔT2 as the divided temperature ΔTa or ΔTb divided into Na or Nb and stores it as the temperature rise value.

In step S102 or step S103, after storing ΔTa or ΔTb as the divided temperature, the outputs of the first heater 104 and the second heater 204 are determined (step S104), and the current room temperature T is the bathroom heating device 100 and the washroom. It is determined whether or not the temperature matches the target temperature To when the two-room heating operation for interlocking and heating the heating equipment 200 is performed (step S105). In other words, it is determined whether or not the temperature of the bathroom 2 detected by the bathroom temperature sensor 107 matches the target temperature To.
In the case of the washroom heating device 200, it is determined whether or not the temperature of the washroom 3 detected by the washroom temperature sensor 207 matches the target temperature To.

In step S105, when it is determined that the current room temperature T matches the target temperature To, a command is sent from the temperature adjusting unit to the heat source driving unit to control the output of the heater so as to maintain the target temperature To. (Step S106). Specifically, if the temperature of the bathroom 2 detected by the bathroom temperature sensor 107 matches the target temperature To, the first temperature adjusting unit 152 instructs the first heat source driving unit 154 to maintain the target temperature To. To control the output of the first heater 104.
In the case of the washroom heating device 200, if the temperature of the washroom 3 detected by the washroom temperature sensor 207 matches the target temperature To, the second temperature adjusting unit is maintained so as to maintain the target temperature To. A command is sent from 252 to the second heat source drive unit 254 to control the output of the second heater 204.

If it is determined in step S105 that the current room temperature T does not match the target temperature To, it is determined whether or not the divided temperature ΔTa is stored as the temperature rise value (step S107). In other words, it is determined whether the divided temperature ΔTa or the divided temperature ΔTb is stored as the temperature rise value. When the divided temperature ΔTa is stored as the temperature increase value, the room temperature is increased by the divided temperature ΔTa (step S108). On the other hand, when the divided temperature ΔTb is stored as the temperature increase value, the room temperature is increased by the divided temperature ΔTb (step S109).
Specifically, it is determined whether the temperature rise value stored in the first temperature adjusting unit 152 is the divided temperature ΔTa or ΔTb, and the room temperature is raised by the divided temperature (ΔTa or ΔTb) determined to be stored. , The first temperature adjusting unit 152 sends a command to the first heat source driving unit 154 to control the output of the first heater 104 and raise the temperature in the bathroom 2.
In the case of the washroom heating device 200, it is determined whether the temperature rise value stored in the second temperature adjusting unit 252 is the divided temperature ΔTa or ΔTb, and only the divided temperature (ΔTa or ΔTb) determined to be stored is determined. A command is sent from the second temperature adjusting unit 252 to the second heat source driving unit 254 to control the output of the second heater 204 so as to raise the room temperature, and the temperature in the washroom 3 is raised.

In step S108 or step S109, after raising the room temperature by ΔTa or ΔTb, it is determined whether the current room temperature T matches the target temperature To when the two-chamber heating operation is performed (step S110).
In other words, it is determined whether or not the temperature of the bathroom 2 detected by the bathroom temperature sensor 107 matches the target temperature To.
In the case of the washroom heating device 200, it is determined whether or not the temperature of the washroom 3 detected by the washroom temperature sensor 207 matches the target temperature To.

If it is determined in step S110 that the current room temperature T matches the target temperature To when performing the two-chamber heating operation, the process proceeds to step S106, and the current room temperature T when performing the two-chamber heating operation is performed. If it is determined that the temperature does not match the target temperature To, the process proceeds to step S111.

In step S111, the temperature difference ΔT'between the bathroom 2 and the washroom 3 is calculated, and it is determined whether or not the calculated ΔT'is smaller than the predetermined temperature (3 ° C.). If it is determined that the temperature difference ΔT'between the bathroom 2 and the washroom 3 is smaller than the predetermined temperature, the process proceeds to step S107, and it is determined that the temperature difference ΔT'between the bathroom 2 and the washroom 3 is not smaller than the predetermined temperature. Then, the process proceeds to step S112.

In step S112, it is determined whether or not the room temperature is higher than that of the other room. Specifically, in the case of the bathroom heating device 100, the temperature of the bathroom 2 detected by the bathroom temperature sensor 107 and the room temperature of the washroom 3 detected by the washroom temperature sensor 207 are set by the first temperature adjusting unit 152. Compare. Then, when it is determined that the room temperature of the bathroom 2 is higher than the room temperature of the washroom 3 which is the other room, the first temperature adjusting unit 152 sends a command to the first heat source driving unit 154 to send a command to the first heater 104. The output is controlled to maintain the current room temperature of the bathroom 2 (step S113). On the contrary, when it is determined that the room temperature of the bathroom 2 is not higher than the room temperature of the washroom 3 which is the other room, the process proceeds to step S107, and the temperature rise value is stored in the bathroom 2 by the divided temperature. The first heater 104 of the bathroom heating device 100 is controlled so as to raise the temperature.
In the case of the washroom heating device 200, in step S112, the temperature of the bathroom 2 detected by the bathroom temperature sensor 107 and the room temperature of the washroom 3 detected by the washroom temperature sensor 207 are adjusted to the second temperature. Compare by part 252. Then, when it is determined that the room temperature of the washroom 3 is higher than the room temperature of the bathroom 2 which is the other room, the second temperature adjusting unit 252 sends a command to the second heat source driving unit 254 to send a command to the second heater 204. The output is controlled to maintain the current room temperature of the bathroom 3 (step S113). On the contrary, if it is determined that the room temperature of the washroom 3 is not higher than the room temperature of the bathroom 2 which is the other room, the process proceeds to step S107, and the inside of the washroom 3 is filled with the divided temperature stored as the temperature rise value. The second heater 204 of the bathroom heating device 200 is controlled so as to raise the temperature of the bathroom.

That is, when the temperature of one room does not reach a predetermined temperature (in this embodiment, the temperature difference between the temperature of one room where the room temperature is low and the temperature of the other room where the room temperature is higher than that of one room). (When the temperature is 3 ° C. or higher), the bathroom heating device 100 or the washroom heating device 200 provided in the other room is operated so as to keep the temperature of the other room, which is higher than that of the one room, constant.

Thus, according to the two-room heating system according to the first embodiment of the present invention, the temperature of the other room of the bathroom 2 or the washroom 3 is set based on the temperature of one room of the bathroom 2 or the washroom 3. Operate at least one of the bathroom heating device 100 or the washroom heating device 200 so that it rises by each division temperature (ΔTa or ΔTb), that is, the temperature of the other room is increased by a predetermined temperature based on the temperature of one room. Can be raised. In other words, the temperature of one room can be raised little by little while monitoring the temperature of the other room. As a result, it is possible to prevent a temperature difference between the bathroom 2 and the washroom 3 from the start of heating to the arrival of the target temperature To.

Further, according to the two-room heating system according to the first embodiment of the present invention, when the temperature of one room of the bathroom 2 or the washroom 3 does not reach a predetermined temperature, the temperature of the other room is maintained constant. In addition, since the equipment provided in the other room is operated, for example, when the temperature of the washroom 3 is higher than that of the bathroom 2, the washroom heating equipment 200 is operated so as to maintain the temperature of the washroom 3 constant. .. As a result, while the temperature of the washroom 3 is kept constant, the bathroom 2 can heat the bathroom 2 by the bathroom heating device 100 to approach the temperature of the washroom 3. On the contrary, when the temperature of the bathroom 2 is higher than that of the washroom 3, the bathroom heating device 100 is operated so as to keep the temperature of the bathroom 2 constant.
As a result, it is possible to more reliably suppress the occurrence of a temperature difference between the bathroom 2 and the washroom 3 from the start of heating to the arrival of the target temperature To.

After reaching the preset target temperature To (step S106), the process of step S106 is performed until a predetermined time elapses from the target temperature To or until the two-chamber heating operation is terminated by the user. I do.

Here, the transition of the space temperature of the bathroom and the washroom of the two-chamber heating system 1 according to the first embodiment of the present invention will be described with reference to FIG. 7.
In FIG. 7, the temperature in the washroom 3 is lower than the temperature in the bathroom 2 before the start of heating (ΔT1 <ΔT2), Na = Nb (= 4), and the bathroom 2 before the start of heating. It is a graph which shows the temperature transition when it is assumed that the temperature difference between the room temperature and the target temperature To is ΔT1 ≦ 10 ° C., and the temperature difference between the room temperature of the bathroom 3 before the start of heating and the target temperature To is ΔT2> 10 ° C.

As shown in FIG. 7, during the predetermined time t after the start of the two-chamber heating operation, the bathroom heating device 100 and the washroom heating device 200 have the temperatures of the bathroom 2 and the washroom 3 before the start of heating and 2 The difference temperature ΔT (ΔT1, ΔT2) between the target temperature To when the room heating operation is performed and the difference temperature ΔT (ΔT1, ΔT2) are calculated, and the divided temperature for dividing the calculated difference temperature ΔT for each predetermined temperature is calculated. As described above, in this example, the temperature difference between the room temperature of the bathroom 2 before the start of heating and the target temperature To is ΔT1 ≦ 10 ° C., and the temperature difference between the room temperature of the washroom 3 before the start of heating and the target temperature To is ΔT2>. Since the temperature is 10 ° C., the first temperature adjusting unit 152 of the bathroom heating device 100 stores the divided temperature ΔTa, and the second temperature adjusting unit 252 of the washroom heating device 200 stores the divided temperature ΔTb as the temperature rise value. In other words, the larger the difference temperature ΔT, the larger the division temperature of the division temperature is set (set to ΔTb in this embodiment), and the smaller the difference temperature ΔT, the smaller the division ratio of the division temperature is set (in this embodiment, ΔTa). Set).
After storing the divided temperature as a temperature rise value, the outputs of the heater 104 and the second heater 204 are determined.

It should be noted that the processing of steps S101 to S104 of FIG. 6 may be performed at the moment when the two-chamber heating operation is started without providing the predetermined time t.

Then, when the predetermined time t elapses, the bathroom heating device 100 is set so that the temperature of the bathroom 2 rises for each division temperature ΔTa so that the temperature T1 of the bathroom 2 and the temperature T2 of the washroom 3 reach the target temperature To. The bathroom heating device 200 is operated so that the temperature of the bathroom 3 rises for each divided temperature ΔTb. At this time, the bathroom heating device 100 operates the bathroom heating device 100 and the bathroom heating device 200 based on the temperature of the washroom 3 and the bathroom heating device 200 based on the temperature of the bathroom 2.

Specifically, in the bathroom heating device 100, the first temperature adjusting unit increases the temperature of the bathroom 2 for each divided temperature ΔTa while monitoring the temperature of the bathroom 3 detected by the bathroom temperature sensor 207. The first heater 104 is controlled by 152. More specifically, when the temperature of the bathroom 2 is raised by ΔTa, if the temperature of the washroom 3 does not reach the predetermined temperature, the first temperature adjusting unit 152 keeps the temperature of the bathroom 2 constant. The first heater 104 of the heating device 100 is controlled. That is, the first heater 104 is controlled so as to keep the temperature of the bathroom 2 constant until the temperature of the washroom 3 reaches a predetermined temperature (until the temperature difference between the bathroom 2 and the washroom 3 becomes small). When the temperature of the washroom 3 reaches a predetermined temperature, the first temperature adjusting unit 152 controls the first heater 104 so that the temperature of the bathroom 2 rises again for each division temperature ΔTa.
On the other hand, in the bathroom heating device 200, while monitoring the temperature of the bathroom 2 detected by the bathroom temperature sensor 107, the second temperature adjusting unit 252 increases the temperature of the bathroom 3 for each divided temperature ΔTb. (2) Controls the heater 204. More specifically, when the temperature of the washroom 3 is raised by ΔTb, if the temperature of the bathroom 2 does not reach the predetermined temperature, the second temperature adjusting unit 252 keeps the temperature of the washroom 3 constant. The second heater 204 of the bathroom heating device 200 is controlled. That is, the second heater 204 is controlled so as to keep the temperature of the washroom 3 constant until the temperature of the bathroom 2 reaches a predetermined temperature (until the temperature difference between the bathroom 2 and the washroom 3 becomes small). When the temperature of the bathroom 2 reaches a predetermined temperature, the second temperature adjusting unit 252 controls the second heater 204 so that the temperature of the washroom 3 rises again for each division temperature ΔTb.

In this way, the first temperature adjusting unit 151 of the first control unit 150 (or the second temperature adjusting unit 251 of the second control unit 250) can change the division ratio of the division temperature. Therefore, since the heating operation can be performed according to the temperature condition, the difference temperature, etc. of the bathroom 2 or the washroom 3, a temperature difference occurs between the bathroom 2 and the washroom 3 from the start of heating to the arrival of the target temperature To. It is possible to more surely suppress the accident.
Further, since the first temperature adjusting unit 151 of the first control unit 150 (or the second temperature adjusting unit 251 of the second control unit 250) sets the division ratio of the division temperature based on the difference temperature ΔT, the difference temperature The division ratio of the division temperature can be changed according to the magnitude. That is, since the heating operation can be performed according to the temperature condition of the bathroom 2 or the washroom 3, it is more certain that a temperature difference will occur between the bathroom and the washroom from the start of heating to the arrival of the target temperature To. It can be suppressed.

Further, as the difference temperature ΔT is larger, the division ratio of the division temperature is set to be larger, so that the arrival time from the start of heating to the target temperature To can be shortened. Therefore, even if the temperature difference between the room temperature before the start of heating and the target temperature To is large, the bathroom 2 is shortened from the start of heating to the arrival of the target temperature while shortening the time from the start of heating to the arrival of the target temperature To. And it is possible to suppress the occurrence of a temperature difference in the washroom 3.

(Second Embodiment)
Next, the transition of the space temperature between the bathroom and the washroom of the two-chamber heating system 1 according to the second embodiment will be described with reference to FIG.
FIG. 8 is a graph showing an example of temperature transition between the bathroom temperature and the washroom temperature of the two-chamber heating system according to the second embodiment. Further, FIG. 8 shows that the temperature in the washroom 3 is lower than the temperature in the bathroom 2 before the start of heating (ΔT1 <ΔT2), Na> Nb, and the room temperature and the target temperature To of the bathroom 2 before the start of heating. It is a graph which showed the temperature transition when it assumed that the temperature difference ΔT1 ≦ 10 degreeC and the temperature difference ΔT2> 10 degreeC between the room temperature of the bathroom 3 before the start of heating and the target temperature To.
In the following description, the same parts as those already described will be designated by the same reference numerals as those already described, and duplicate description will be omitted.

As shown in FIG. 8, the number of divisions Na or Nb is set according to the difference temperature ΔT. Specifically, the temperature in the bathroom 2 before the start of heating is compared with the temperature in the washroom 3 before the start of heating, and the number of divisions with the lower temperature (larger difference temperature ΔT) is divided into the other. Set less than the number. In this example, since ΔT1 <ΔT2, Nb is set to be smaller than the number of divisions Na. That is, by making the number of divisions Nb of ΔT2 smaller than the number of divisions Na, the division ratio of ΔTb is set to be larger than ΔTa.

Therefore, the larger the difference temperature ΔT, the larger the division ratio of the division temperature is set, so that the time to reach the target temperature To can be shortened. Therefore, even if the difference between the temperature of the bathroom 2 or the washroom 3 before the start of heating and the target temperature To is large, a temperature difference occurs between the bathroom 2 and the washroom 3 from the start of heating to the arrival of the target temperature To. It is possible to shorten the time from the start of heating to the arrival of the target temperature To while suppressing the occurrence of the temperature.

(Third Embodiment)
Next, the transition of the space temperature of the bathroom and the washroom of the two-chamber heating system 1 according to the third embodiment will be described with reference to FIG.
FIG. 9 is a graph showing an example of temperature transition between the bathroom temperature and the washroom temperature of the two-chamber heating system according to the third embodiment. Further, in FIG. 9, the temperature inside the washroom 3 is lower than the temperature of the bathroom 2 before the start of heating (ΔT1 <ΔT2), and the temperature difference between the room temperature of the bathroom 2 before the start of heating and the target temperature To is ΔT1 ≦ 10 ° C. It is a graph which showed the temperature transition when it is assumed.
In the following description, the same parts as those already described will be designated by the same reference numerals as those already described, and duplicate description will be omitted.

Specifically, the bathroom heating device 100 calculates the difference temperature ΔT1 between the temperature of the bathroom 2 before the start of heating and the target temperature To when the two-room heating operation is performed, and determines the calculated difference temperature ΔT1. The division temperature ΔTa to be divided for each temperature is calculated. As described above, in this example, since the temperature difference between the room temperature of the bathroom 2 before the start of heating and the target temperature To is ΔT1 ≦ 10 ° C., the first temperature adjusting unit 152 of the bathroom heating device 100 has a divided temperature ΔTa. Is stored as the temperature rise value. Then, the bathroom heating device 100 is operated so that the temperature of the bathroom 2 rises for each division temperature ΔTa so that the temperature T1 of the bathroom 2 reaches the target temperature To. At this time, the bathroom heating device 100 monitors the temperature of the bathroom 3 detected by the bathroom temperature sensor 207, and the first temperature adjusting unit 152 increases the temperature of the bathroom 2 for each divided temperature ΔTa. The first heater 104 is controlled.

Specifically, when the temperature of the bathroom 2 is raised by ΔTa, if the temperature of the washroom 3 does not reach the predetermined temperature, the first temperature adjusting unit 152 heats the bathroom so as to keep the temperature of the bathroom 2 constant. The first heater 104 of the device 100 is controlled. That is, the first heater 104 is controlled so as to keep the temperature of the bathroom 2 constant until the temperature of the washroom 3 reaches a predetermined temperature (until the temperature difference between the bathroom 2 and the washroom 3 becomes small). When the temperature of the washroom 3 reaches a predetermined temperature, the first temperature adjusting unit 152 controls the first heater 104 so that the temperature of the bathroom 2 rises again for each division temperature ΔTa.

On the other hand, the washroom heating device 200 performs a normal heating operation. Specifically, after the elapse of the predetermined time t, the second heater 204 of the washroom heating device 200 is operated by the second temperature adjusting unit 252 so that the transition of the space temperature of the washroom 3 reaches the target temperature To with a constant inclination. To control. In other words, the washroom heating device 200 does not control to raise the room temperature of the washroom 3 for each divided temperature based on the temperature of the bathroom 2.

As in the present embodiment, at least one of the bathroom heating device 100 and the washroom heating device 200 may be operated so that the room temperature rises for each divided temperature.

Further, in FIG. 10, the temperature in the washroom 3 is lower than the temperature in the bathroom 2 before the start of heating (ΔT1 <ΔT2), and the temperature difference between the room temperature of the washroom 3 before the start of heating and the target temperature To is ΔT2>. It is a graph which showed the temperature transition at the time of assuming 10 degreeC.
In the following description, the same parts as those already described will be designated by the same reference numerals as those already described, and duplicate description will be omitted.

As shown in FIG. 10, in the present embodiment, only the washroom heating device 200 is controlled to raise the room temperature for each divided temperature. Specifically, the washroom heating device 200 calculates the difference temperature ΔT2 between the temperature of the washroom 3 before the start of heating and the target temperature To when the two-chamber heating operation is performed. Then, the division temperature for dividing the calculated ΔT2 for each predetermined temperature is calculated. Subsequently, until the room temperature of the washroom 3 reached a predetermined temperature, the second heater 204 was controlled so that the room temperature of the washroom 3 rose for each division temperature ΔTb, and the room temperature of the washroom 3 reached the predetermined temperature. After that, the second heater 204 is controlled so that the room temperature of the washroom 3 rises for each division temperature ΔTa.
The predetermined temperature here is a temperature lower than the target temperature To, for example, the temperature when the temperature difference between the target temperature To and the washroom 3 approaches within a predetermined range, or the temperature between the bathroom 2 and the washroom 3. This is the temperature when the temperature difference between the temperature and the temperature approaches within a predetermined range.

On the other hand, the bathroom heating device 100 performs a normal heating operation. Specifically, after the elapse of the predetermined time t, the first heater 104 of the bathroom heating device 100 is set by the first temperature adjusting unit 152 so that the transition of the space temperature of the bathroom 2 reaches the target temperature To with a constant inclination. Control. In other words, the bathroom heating device 100 does not control to raise the room temperature of the bathroom 2 for each divided temperature based on the temperature of the washroom 3.

That is, until the room temperature of the washroom 3 reaches a predetermined temperature, the room temperature of the washroom 3 is raised for each division temperature ΔTb of a large division ratio, and after the room temperature of the washroom 3 reaches the predetermined temperature, the target temperature To Up to, the room temperature of the washroom 3 is raised for each division temperature ΔTa of a small division ratio.
As described above, the larger the difference temperature ΔT is, the larger the division ratio of the division temperature is set, so that the arrival time from the start of heating to the target temperature To can be shortened. Therefore, even if the temperature difference between the room temperature before the start of heating and the target temperature To is large, the bathroom 2 is shortened from the start of heating to the arrival of the target temperature while shortening the time from the start of heating to the arrival of the target temperature To. And it is possible to suppress the occurrence of a temperature difference in the washroom 3.
