However, in the conventional two-room heating system described above, the difference in performance between the heating device provided in the bathroom and the heating device provided in the bathroom, the size of the bathroom and the bathroom, and the thermal insulation effect of each room Depending on the difference in outside air, the time from the start of heating until reaching the target temperature differs in each room. That is, a temperature difference occurs between the bathroom and the washroom from the start of heating until the target temperature is reached in each room.
In this way, when the user tries to use the bathroom through the washroom when the temperature difference between the bathroom and the washroom has occurred since the start of heating and before the target temperature has been reached, There is a concern that a heat shock may occur due to a temperature difference from the bathroom. There is also a concern that when a user of a bathroom or bathroom feels that one room is warm and moves to the other room, the user feels uncomfortable due to the temperature difference.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a two-room heating system that suppresses heat shock and further improves comfort.

  In order to achieve the above object, a two-room heating system according to one aspect of the present invention is a two-room heating system that heats a bathroom and a bathroom adjacent to the bathroom in conjunction with each other. A bathroom heating device that warms the bathroom, a bathroom heating device that warms the bathroom, a control unit that controls the operation of the bathroom heating device and the bathroom heating device, and a bathroom temperature detection means that detects the bathroom temperature And a bathroom temperature detection means for detecting the bathroom temperature, and the control unit detects the bathroom temperature and the bathroom temperature detected by the bathroom temperature detection means and the bathroom temperature detection means, the bathroom heating device and the bathroom heating. Calculate the difference temperature between the target temperature when the equipment is warmed in conjunction with each other, calculate the division temperature that divides the calculated difference temperature for each predetermined temperature, and based on the temperature of one room in the bathroom or washroom And Temperature of the chamber or lavatory of the other room to rise for each divided temperature, operating at least one bathroom heating appliance or toilet heating appliance.

  According to this configuration, based on the temperature of one room of the bathroom or the toilet, the temperature of the other room of the bathroom or the toilet increases so as to increase for each divided temperature. At least one is operated, that is, the temperature of the other room can be increased by a predetermined temperature based on the temperature of one room. Thereby, it can suppress that a temperature difference generate | occur | produces in a bathroom and a washroom from the start of heating to reaching | attaining target temperature.

  In the two-room heating system according to one aspect of the present invention, preferably, the control unit maintains the temperature of the other room constant when the temperature of the one room does not reach a predetermined temperature. Thus, the bathroom heating device or the washroom heating device provided in the other room is operated.

  According to this configuration, when the temperature of one room does not reach the predetermined temperature, the device provided in the other room is operated so as to keep the temperature of the other room constant. If the temperature of the washroom is high, the washroom heater is operated so as to keep the temperature of the washroom constant. Thereby, while maintaining the temperature of a washroom constant, a bathroom can be heated with bathroom heating equipment and it can approach the temperature of a washroom. Therefore, it can suppress more reliably that a temperature difference will generate | occur | produce in a bathroom and a washroom from the start of heating to reaching | attaining target temperature.

  In the two-room heating system according to one embodiment of the present invention, preferably, the control unit can change the division ratio of the division temperature.

  According to this configuration, since the heating operation can be performed in accordance with the temperature condition or differential temperature of the bathroom or the washroom, a temperature difference occurs in the bathroom and the washroom from the start of heating to the arrival of the target temperature. This can be suppressed more reliably.

  In the two-room heating system according to one aspect of the present invention, preferably, the control unit sets the division ratio of the division temperature based on the differential temperature.

  According to this configuration, since the division ratio of the division temperature is set based on the difference temperature, for example, the division ratio of the division temperature can be changed according to the magnitude of the difference temperature. In other words, since the heating operation can be performed according to the temperature condition of the bathroom or the washroom, it is possible to more reliably suppress the occurrence of a temperature difference in the bathroom and the washroom from the start of heating to the arrival of the target temperature. Can do.

  In the two-room heating system according to one aspect of the present invention, preferably, the division ratio of the division temperature is set to be larger as the differential temperature is larger.

  According to this configuration, as the difference temperature is larger, the division ratio of the division temperature is set to be larger, so that the arrival time to the target temperature can be advanced. Therefore, even if the difference between the room temperature before the start of heating and the target temperature is large, the time from the start of heating to the arrival of the target temperature is shortened, and the bathroom and the washroom are reached from the start of heating to the arrival of the target temperature. Generation of a temperature difference can be suppressed.

  Next, with reference to FIG.6 and FIG.7, operation | movement and an effect | action of the two-room heating system which concern on 1st embodiment of this invention are demonstrated.

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

As shown in FIG. 6, 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). A first differential temperature ΔT1 that is a difference between the temperature of the bathroom 2 and the target temperature when performing the two-room heating operation is calculated by the first temperature adjustment unit 152 of the bathroom heating device 100 (step S101). Specifically, the first differential 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.
If the first differential temperature ΔT1 is higher than a predetermined temperature (absolute value: 10 ° C. in the present embodiment), the process proceeds to step S103, and otherwise, the process proceeds to step S102.
That is, which of ΔTa and ΔTb, which will be described later, is stored as a temperature increase value is determined according to the magnitude of the difference temperature ΔT.
Here, also in the washroom heating device 200, the second temperature adjustment unit 252 calculates the second differential temperature ΔT2 that is the difference between the temperature of the washroom 3 and the target temperature when performing two-room heating. If the second differential temperature ΔT2 is higher than (10 ° C. in this embodiment), the process proceeds to step S103, and otherwise, the process proceeds to step S102. Thus, in 1st embodiment of this invention, the washroom heating apparatus 200 also performs operation | movement of step S100-step S113.

When the process proceeds to step S102, a value obtained by dividing the calculated difference temperature ΔT by Na is set as ΔTa and stored as a temperature increase value. Specifically, the first temperature adjustment unit 152 (second temperature adjustment unit 252) stores the divided temperature ΔTa obtained by dividing the calculated first difference temperature ΔT1 by Na as a temperature increase value.
On the other hand, when proceeding to step S103, a value obtained by dividing the calculated difference temperature ΔT by Nb is set as ΔTb and stored as a temperature increase value. Similarly to the case of ΔTa, the first temperature adjustment unit 152 (second temperature adjustment unit 252) stores the divided temperature ΔTb obtained by dividing the calculated first difference temperature ΔT1 by Nb as a temperature increase value.
In the case of the washroom heating device 200, the second temperature adjustment unit 252 stores the calculated second differential temperature ΔT2 as a divided temperature ΔTa or ΔTb divided by Na or Nb, and stores it as a temperature increase value.

In step S102 or step S103, after ΔTa or ΔTb is stored as the division temperature, the outputs of the first heater 104 and the second heater 204 are determined (step S104), and the current room temperature T is determined based on the bathroom heater 100 and the washroom. It is determined whether or not the temperature matches the target temperature To when the two-room heating operation for heating the heating device 200 in conjunction with the heating device 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 bathroom heating device 200, it is determined whether or not the temperature of the bathroom 3 detected by the bathroom temperature sensor 207 matches the target temperature To.

If it is determined in step S105 that the current room temperature T matches the target temperature To, a command is sent from the temperature adjustment unit to the heat source drive unit so as to maintain the target temperature To, and the output of the heater is controlled. (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 adjustment unit 152 instructs the first heat source driving unit 154 to maintain the target temperature To. And the output of the first heater 104 is controlled.
In the case of the bathroom heating device 200, if the temperature of the bathroom 3 detected by the bathroom temperature sensor 207 coincides with the target temperature To, the second temperature adjustment unit maintains 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 increase value (step S107). In other words, it is determined whether the divided temperature ΔTa or the divided temperature ΔTb is stored as the temperature increase value. When the division temperature ΔTa is stored as the temperature increase value, the room temperature is raised by the division temperature ΔTa (step S108). On the other hand, when the division temperature ΔTb is stored as the temperature increase value, the room temperature is raised by the division temperature ΔTb (step S109).
Specifically, it is determined whether the temperature increase value stored in the first temperature adjustment unit 152 is the divided temperature ΔTa or ΔTb, and the room temperature is increased by the divided temperature (ΔTa or ΔTb) determined to be stored. Then, a command is sent from the first temperature adjusting unit 152 to the first heat source driving unit 154 to control the output of the first heater 104 and to raise the temperature in the bathroom 2.
In the case of the bathroom heating device 200, it is determined whether the temperature increase 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. A command is sent from the second temperature adjustment 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 the room temperature is raised by ΔTa or ΔTb, it is determined whether the current room temperature T matches the target temperature To when performing the two-room heating operation (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 bathroom heating device 200, it is determined whether or not the temperature of the bathroom 3 detected by the bathroom temperature sensor 207 matches the target temperature To.

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

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

In step S112, it is determined whether the room temperature is higher than 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 bathroom 3 detected by the bathroom temperature sensor 207 are determined by the first temperature adjustment unit 152. Compare. And if it determines with the room temperature of the bathroom 2 being higher than the room temperature of the washroom 3 which is the other room, it will send a command from the first temperature adjustment unit 152 to the first heat source drive unit 154 and the first heater 104 will The output is controlled to maintain the current room temperature of the bathroom 2 (step S113). On the contrary, if 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 room temperature in the bathroom 2 is equal to the divided temperature stored as the temperature rise value. The first heater 104 of the bathroom heating device 100 is controlled to increase the temperature.
In the case of the bathroom 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 bathroom 3 detected by the bathroom temperature sensor 207 are set as the second temperature adjustment. The comparison is made by the part 252. And if it determines with the room temperature of the washroom 3 being higher than the room temperature of the bathroom 2 which is the other room, a command will be sent from the 2nd temperature adjustment part 252 to the 2nd heat source drive part 254, and the 2nd heater 204 of The output is controlled and the current room temperature of the bathroom 3 is maintained (step S113). On the other hand, if it is determined that the room temperature of the bathroom 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 bathroom 3 is equal to the divided temperature stored as the temperature rise value. The second heater 204 of the washroom heating device 200 is controlled so as to increase the temperature.

  That is, when the temperature of one room does not reach the 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 one room) When the temperature is 3 ° C. or higher), the bathroom heating device 100 or the bathroom heating device 200 provided in the other room is operated so that the temperature of the other room, which is higher in room temperature than the one room, is kept constant.

  Thus, according to the two-room heating system in the first embodiment of the present invention, based on the temperature of one room of the bathroom 2 or the toilet 3, the temperature of the other room of the bathroom 2 or the toilet 3 is At least one of the bathroom heating device 100 or the bathroom heating device 200 is operated so as to increase for each divided temperature (ΔTa or ΔTb), that is, the temperature of the other room is set by a predetermined temperature based on the temperature of one room. Can be raised. In other words, it is possible to gradually increase the temperature of one room while monitoring the temperature of the other room. Thereby, it can suppress that a temperature difference generate | occur | produces in the bathroom 2 and the washroom 3 from the start of heating to reaching the target temperature To.

Moreover, according to the two-room heating system in 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 device 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 device 200 is operated so as to keep the temperature of the washroom 3 constant. . Thereby, while maintaining the temperature of the washroom 3 constant, the bathroom 2 can heat the bathroom 2 with the bathroom heating device 100 and can be brought close to the temperature of the washroom 3. On the other hand, when the temperature of the bathroom 2 is higher than that of the bathroom 3, the bathroom heating device 100 is operated so as to keep the temperature of the bathroom 2 constant.
Thereby, it can suppress more reliably that a temperature difference will generate | occur | produce in the bathroom 2 and the washroom 3 from the heating start to the target temperature To reach | attainment.

  After reaching the preset target temperature To (step S106), the process of step S106 is performed until a predetermined time has elapsed from the target temperature To or until the user completes the two-room heating operation. I do.

Here, transition of the space temperature of the bathroom and the washroom of the two-room heating system 1 according to the first embodiment of the present invention will be described with reference to FIG.
In FIG. 7, the temperature in the bathroom 3 is lower (ΔT1 <ΔT2) and Na = Nb (= 4) than the temperature in the bathroom 2 before the start of heating, and the bathroom 2 before the start of heating. It is the graph which showed temperature transition at the time of assuming temperature difference (DELTA) T1 <= 10 degreeC of room temperature and target temperature To of the room temperature of the bathroom 3 before the start of heating, and temperature difference (DELTA) T2> 10 degreeC of target temperature To.

As shown in FIG. 7, during a predetermined time t after the two-room heating operation is started, 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 A difference temperature ΔT (ΔT1, ΔT2) between the target temperature To and the room heating operation is calculated, respectively, and a division temperature for dividing the calculated difference temperature ΔT for each predetermined temperature is calculated. As described above, in this example, the temperature difference ΔT1 ≦ 10 ° C. between the room temperature of the bathroom 2 before the start of heating and the target temperature To, and the temperature difference ΔT2 between the room temperature of the bathroom 3 before the start of heating and the target temperature To> Since it is 10 degreeC, the 1st temperature adjustment part 152 of the bathroom heating appliance 100 memorize | stores division | segmentation temperature (DELTA) Ta and the 2nd temperature adjustment part 252 of the washroom heating appliance 200 memorize | stores division | segmentation temperature (DELTA) Tb as a temperature rise value. In other words, the larger the difference temperature ΔT, the higher the division ratio of the division temperature (in this embodiment, set to ΔTb), and the smaller the difference temperature ΔT, the smaller the division ratio of the division temperature (in this embodiment, to ΔTa). Set).
After the division temperature is stored as the temperature rise value, the outputs of the heater 104 and the second heater 204 are determined.

  In addition, you may make it perform the process of step S101-step S104 of FIG. 6 at the moment the two-room heating operation is started without providing the predetermined time t.

  Then, when the predetermined time t has elapsed, the bathroom heating device 100 is set so that the temperature of the bathroom 2 rises for each divided temperature ΔTa so that the temperature T1 of the bathroom 2 and the temperature T2 of the toilet 3 reach the target temperature To. The toilet room 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 bathroom 3, and the bathroom heating device 200 operates based on the temperature of the bathroom 2.

Specifically, in the bathroom heating device 100, the first temperature adjusting unit is configured to increase 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 does not reach a predetermined temperature when the temperature of the bathroom 2 is increased by ΔTa, the first temperature adjustment 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 that the temperature of the bathroom 2 is kept constant until the temperature of the bathroom 3 reaches a predetermined temperature (until the temperature difference between the bathroom 2 and the bathroom 3 becomes small). When the temperature of the washroom 3 reaches a predetermined temperature, the first temperature adjustment unit 152 controls the first heater 104 so that the temperature of the bathroom 2 rises again for each divided temperature ΔTa.
On the other hand, in the bathroom heating device 200, the temperature of the bathroom 3 detected by the bathroom temperature sensor 107 is monitored, and the second temperature adjustment unit 252 causes the temperature of the bathroom 3 to rise for each divided temperature ΔTb. The two heaters 204 are controlled. More specifically, when the temperature of the bathroom 3 does not reach the predetermined temperature when the temperature of the bathroom 3 is increased by ΔTb, the second temperature adjustment unit 252 maintains the temperature of the bathroom 3 constant. The second heater 204 of the washroom heating device 200 is controlled. That is, the second heater 204 is controlled so that the temperature of the bathroom 3 is kept constant until the temperature of the bathroom 2 reaches a predetermined temperature (until the temperature difference between the bathroom 2 and the bathroom 3 becomes small). When the temperature of the bathroom 2 reaches a predetermined temperature, the second temperature adjustment unit 252 controls the second heater 204 so that the temperature of the washroom 3 rises again for each divided temperature ΔTb.

Thus, the first temperature adjustment unit 151 of the first control unit 150 (or the second temperature adjustment 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 in accordance with the temperature condition or difference temperature of the bathroom 2 or the washroom 3, a temperature difference occurs in the bathroom 2 and the washroom 3 from the start of heating until reaching the target temperature To. It can suppress more reliably.
Furthermore, since the first temperature adjustment unit 151 of the first control unit 150 (or the second temperature adjustment unit 251 of the second control unit 250) sets the division ratio of the division temperature based on the difference temperature ΔT, The division ratio of the division temperature can be changed according to the size. That is, since the heating operation can be performed in accordance with the temperature condition of the bathroom 2 or the bathroom 3, the temperature difference between the bathroom and the bathroom is more reliably generated from the start of heating until the target temperature To is reached. Can be suppressed.

  Moreover, since the division | segmentation ratio of division | segmentation temperature is set so large that difference temperature (DELTA) T is large, the arrival time from the heating start to the target temperature To can be advanced. Therefore, even when the temperature difference between the room temperature before the start of heating and the target temperature To is large, the bathroom 2 is reduced from the start of heating to the arrival of the target temperature To while shortening the time from the start of heating to the arrival of the target temperature To. And it can suppress that a temperature difference generate | occur | produces in the washroom 3. FIG.

(Second embodiment)
Next, transition of the temperature of the bathroom and the bathroom in the two-room heating system 1 according to the second embodiment will be described with reference to FIG.
FIG. 8 is a graph showing an example of the temperature transition of the bathroom temperature and the washroom temperature of the two-room heating system according to the second embodiment. FIG. 8 shows that the temperature in the bathroom 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 the graph which showed the temperature transition when assuming temperature difference (DELTA) T1 <= 10 degreeC and temperature difference (DELTA) T2> 10 degreeC of the room temperature of the washroom 3 before heating start, and target temperature To.
In the following description, parts that are the same as those already described are given the same reference numerals as those already described, and redundant descriptions are omitted.

  As shown in FIG. 8, the division number 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 (the difference temperature ΔT is larger) is determined as the other division. Set it less than the number. In this example, since ΔT1 <ΔT2, Nb is set to be smaller than the division number Na. That is, by making the division number Nb of ΔT2 smaller than the division number Na, the division ratio of ΔTb is set larger than ΔTa.

  Therefore, the larger the difference temperature ΔT is, the larger the division ratio of the division temperature is set, so that the arrival time to the target temperature To can be advanced. 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 in the bathroom 2 and the washroom 3 from the start of heating until the target temperature To is reached. The time from the start of heating to reaching the target temperature To can be shortened.

(Third embodiment)
Next, transition of the space temperature of the bathroom and the washroom of the two-room 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 of the bathroom temperature and the washroom temperature of the two-room heating system according to the third embodiment. 9 shows that the temperature in the bathroom 3 is lower than the temperature of the bathroom 2 before the start of heating (ΔT1 <ΔT2), and the temperature difference ΔT1 ≦ 10 ° C. between the room temperature of the bathroom 2 before the start of heating and the target temperature To. It is the graph which showed the temperature transition at the time of assuming.
In the following description, parts that are the same as those already described are given the same reference numerals as those already described, and redundant descriptions are omitted.

  As shown in FIG. 9, in the present embodiment, only the bathroom heating device 100 performs control to increase the room temperature for each divided temperature. Specifically, the bathroom heating device 100 calculates a difference temperature ΔT1 between the temperature of the bathroom 2 before the start of heating and the target temperature To when performing the two-room heating operation, and the calculated difference temperature ΔT1 is predetermined. A division temperature ΔTa divided for each temperature is calculated. As described above, in this example, since the temperature difference ΔT1 ≦ 10 ° C. between the room temperature of the bathroom 2 before the start of heating and the target temperature To, the first temperature adjustment unit 152 of the bathroom heating device 100 is divided by the divided temperature ΔTa. Is stored as a temperature rise value. Then, the bathroom heating device 100 is operated so that the temperature of the bathroom 2 rises for each divided 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 adjustment 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 increased by ΔTa and the temperature of the washroom 3 does not reach a predetermined temperature, the first temperature adjustment unit 152 heats the bathroom so that the temperature of the bathroom 2 is maintained constant. The first heater 104 of the device 100 is controlled. That is, the first heater 104 is controlled so that the temperature of the bathroom 2 is kept constant until the temperature of the bathroom 3 reaches a predetermined temperature (until the temperature difference between the bathroom 2 and the bathroom 3 becomes small). When the temperature of the washroom 3 reaches a predetermined temperature, the first temperature adjustment unit 152 controls the first heater 104 so that the temperature of the bathroom 2 rises again for each divided 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 used by the second temperature adjustment 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 bathroom heating device 200 does not perform control to increase the room temperature of the bathroom 3 for each divided temperature based on the temperature of the bathroom 2.

  As in this embodiment, a configuration in which at least one of the bathroom heating device 100 or the bathroom heating device 200 is operated so that the temperature of the room rises for each division temperature may be employed.

(Fourth embodiment)
Next, transition of the space temperature of the bathroom and the washroom of the two-room heating system 1 according to the fourth embodiment will be described with reference to FIG.
FIG. 10: is a graph which shows an example of the temperature transition of the bathroom temperature and washroom temperature of the 2 room heating system which concerns on 4th embodiment. It is. FIG. 10 shows that the temperature in the bathroom 3 is lower than the temperature in the bathroom 2 before the start of heating (ΔT1 <ΔT2), and the temperature difference ΔT2 between the room temperature of the bathroom 3 before the start of heating and the target temperature To> It is the graph which showed the temperature transition at the time of assuming 10 degreeC.
In the following description, parts that are the same as those already described are given the same reference numerals as those already described, and redundant descriptions are omitted.

As shown in FIG. 10, in the present embodiment, only the washroom heating device 200 performs control to increase the room temperature for each division temperature. Specifically, the washroom heating device 200 calculates a difference temperature ΔT2 between the temperature of the washroom 3 before the start of heating and the target temperature To when performing the two-room heating operation. And the division | segmentation temperature which divides | segments calculated (DELTA) T2 for every predetermined temperature is calculated. Subsequently, until the room temperature of the washroom 3 reaches a predetermined temperature, the second heater 204 is controlled so that the room temperature of the washroom 3 rises for each divided temperature ΔTb, and the room temperature of the washroom 3 reaches the predetermined temperature. Thereafter, the second heater 204 is controlled so that the room temperature of the washroom 3 rises for each divided temperature ΔTa.
Here, the predetermined temperature is a temperature lower than the target temperature To, for example, the temperature when the temperature difference between the target temperature To and the bathroom 3 approaches within a predetermined range, or the bathroom 2 and the bathroom 3 And the temperature when the temperature difference 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 temperature adjustment unit 152 causes the first heater 104 of the bathroom heating device 100 to be changed 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 perform control to increase the room temperature of the bathroom 2 for each division temperature based on the temperature of the bathroom 3.

That is, until the room temperature of the washroom 3 reaches a predetermined temperature, the room temperature of the washroom 3 is increased for each large division ratio ΔTb, and after the room temperature of the washroom 3 reaches the predetermined temperature, the target temperature To Until the room temperature of the washroom 3 is increased for each division temperature ΔTa having a small division ratio.
Thus, since the division | segmentation ratio of division | segmentation temperature is set so large that difference temperature (DELTA) T is large, the arrival time from the heating start to the target temperature To can be advanced. Therefore, even when the temperature difference between the room temperature before the start of heating and the target temperature To is large, the bathroom 2 is reduced from the start of heating to the arrival of the target temperature To while shortening the time from the start of heating to the arrival of the target temperature To. And it can suppress that a temperature difference generate | occur | produces in the washroom 3. FIG.

  In addition, in 4th embodiment, you may make it the bathroom heating apparatus 100 perform the same control as the washroom heating apparatus 200. FIG. Conversely, the bathroom heating device 200 may be operated in a normal heating operation, and the bathroom heating device 100 may be operated so that the room temperature of the bathroom 2 is increased for each divided temperature.

  Further, for example, each time the division temperature is increased by one step, the division ratio of the division temperature may be controlled to be reduced.

  The elements included in each of the embodiments described above can be combined as much as technically possible, and combinations thereof are also included in the scope of the present invention as long as they include the features of the present invention.
