Each is provided.

Next, the general hot water supply operation will be described. Press the hot water supply switch of the bath remote control 117 or the hot water supply remote control 77 to open the hot water supply curan 21 and turn on the hot water supply heat exchanger 5.
When a predetermined amount or more of water flows into 2, hot water supply burner 51 ignites to start proportional control, and continuously changes the gas flow rate and the air amount to maintain the tap water temperature at the set temperature. Hot water supply curan 2
When 1 is closed, the system controller 9 detects the water stop signal from the hot water supply amount sensor 26, stops the gas supply, and extinguishes the fire. After the post-purge operation, the heating fan 18 and the hot water supply fan 19 are stopped.

Next, the heating operation will be described. When the system controller 9 detects an operation signal from any one of the high-temperature radiator 65 and the low-temperature radiators 82, 92, and 102, the heating circulating pump 22 rotates, and the heating hot-water thermistor 25 (or the heating input water thermistor 24). When the temperature of the heating water falls below a predetermined value, the heating fan 18 and the hot water supply fan 19 rotate, ignite the heating burner 41, and start proportional control.

When only the high-temperature radiator 65 is operated, the bath heat valve 121 and the low-temperature radiator 82,
Heating valves 83, 93, and 103 of 92 and 102 are closed, and the heating water pressurized by the heating circulation pump 22 flows to the heating and high-temperature going pipe 66 without flowing to the heating and low-temperature going pipe 47, and the heating heat exchanger 42. After being heated to 80 ° C., it does not flow to the bathtub water heating pipe 67, branches off at the high-temperature radiator 65 and the bypass pipe 34, radiates heat at the high-temperature radiator 65, and returns to the expansion tank 62.

By the way, the heating water is supplied to the bypass pipe 3 during heating.
The reason for flowing the heating water to 4 is that it is necessary to secure the flow path of the heating water pressurized by the heating circulation pump 22 because the response of the thermal valve is generally slow. Since the diameter of the bypass pipe 34 is smaller than the diameter of the heating high-temperature pipe 66, much of the heating water flowing through the high-temperature heating pipe 66 flows into the high-temperature radiator 65 and contributes to heating of the room, and the heating efficiency is high.

On the other hand, when only the low-temperature radiators 82, 92, and 102 are operated, the heating valve 65a of the high-temperature radiator 65 is closed, and the heating water pressurized by the heating circulating pump 22 is supplied to the heating low-temperature outlet pipe. The branching path 47 and the high-temperature heating pipe 66 are branched, heated by the heating heat exchanger 42, and returned to the expansion tank 62 through the bypass pipe 34 without passing through the high-temperature radiator 65. In addition, the heating water passing through the heating low-temperature pipe 47 is also supplied to the low-temperature radiators 82 and 9.
After the heat is released at 2 and 102, the flow returns to the expansion tank 62.

That is, the heating water starting from the expansion tank 62 and flowing through the low-temperature radiators 82, 92 and 102 is not heated by the heating heat exchanger 42, but is heated by the low-temperature radiators 82, 92 and 1.
After the heat is dissipated in 02, the mixture is heated by the heating heat exchanger 42 and mixed with the heating water flowing through the bypass pipe 34 to increase the temperature. The temperature of the mixed hot water is detected by the heating water input thermistor 24 and is controlled so as to be maintained at about 60 ° C. When the high-temperature radiator 65 is used and when the low-temperature / high-temperature radiator is used at the same time, the heating water temperature detected by the heating hot water thermistor 25 is controlled to be kept at about 80 ° C.

Incidentally, the low-temperature radiators 82, 92, 102
In the case where the heat radiation amount is large, the flow rate of the heating water flowing through the low-temperature heating bypass pipe 34 having a small diameter is small, so that the heating to the low-temperature radiators 82, 92, and 102 cannot be caught up. And the high-temperature heating water heated by the heating heat exchanger 42 flows through the large-diameter bathtub water heating pipe 67 to be mixed with the heat-dissipated heating water flowing through the heating return pipe 46 so that the low-temperature radiator 82 , 92, 102.

In the heating control, the gas proportional control is performed according to the load variation within the combustion capacity range of the heating combustion main body 60. However, when the load on the high-temperature radiator 65 and the low-temperature radiators 82, 92, and 102 is small, that is, when the heat release amount is small, the circulation heating water is overheated even if the heating combustion main body 60 is burned with the minimum capacity. Therefore, the heating water is kept at the set temperature by stopping the combustion of the heating burner 41 until the heating water temperature decreases to a predetermined temperature, and performing on / off control to restart the combustion after the water temperature decreases. When the heating water level electrode 63 detects shortage of the heating water, the water injection solenoid valve 123 is opened, and the general hot water supply pipe 37 is connected to the water injection pipe 122.
Automatically replenish the heating water via. The same applies when the heating / combustion main body 60 is used for the first time after the purchase of the hot water supply / room heater 1.

Generally, each room MR1, SR1, SR2
Is individually heated by the floor, a person in the room operates using a remote control provided in the room. However, in this embodiment, the floor heating control of the sub-rooms SR1 and SR2 can be performed using the main remote controller 81 of the main room MR1.

As shown in FIG. 3, the main remote controller 81 has a display 8 for displaying operating information such as the presence or absence of a heating operation and a set temperature, the name of a room to be controlled, and the current time.
4, an operation switch 85 for turning on / off the heating operation (hereinafter, referred to as an operation switch 85).
A switch is expressed as SW), an up SW 86U for increasing / decreasing a set temperature, and a down SW 86D (hereinafter referred to as an up / down SW 86 when these are not distinguished) are further provided. A room switching switch 88 for switching a target room is provided. The display 84 always displays the current time except when the timer is set. Further, the main remote controller 81 is also provided with a timer function for setting the operation ON / OFF timing of the floor heating provided in the room to be controlled by simultaneously pressing the up / down SW 86. The sub remote controllers 91 and 101 have the same configuration as the main remote controller 81 except for the room switch SW.

Next, a method of setting a room to be controlled by the main remote controller 81 (turning the operation on / off, changing the set temperature, setting the timer) will be described with reference to FIG. According to this setting method, the room controlled by the main remote controller 81 is set to the main room MR1 (n = 0) and the sub room SR1 (n =
1), a sub-room SR2 (n = 2).

When the operation switch of the main remote controller 81 is pressed and turned on, a control routine for setting a control target of the main remote controller 81 is started, and a variable n is set to 0 (S1).
That is, at this stage, the control target of the main remote controller 81 is the main room MR1.

Next, it is determined whether or not the room switching switch 88 has been pressed (S2). If it has not been pressed, the process proceeds from step 6 to step 7 since n = 0, so that the main room M
R1 operation status (room name, set temperature, presence or absence of operation,
That is, "running" and "stop" are displayed on the display 84 of the main remote controller 81, and the control target of the main remote controller 81 is set to the main room MR1 (S8), and step 2 is performed.
Return to

If it is determined in step 2 that the room switch SW 88 has been pressed, it is determined in step 3 whether n = 2. When the room switch SW 88 is first pressed after the operation SW 85 is turned off, the process proceeds to step 5 because n = 0, and the variable n
Is set to n = 1, and the process proceeds from step 6 to step 9 to display the operation status of the sub room SR1 on the display 84 of the main remote controller 81, and the main remote controller 8
1 is set in the sub-room SR1 (S1
0), and return to step 2.

When the room switch SW88 is further pressed from the state where the sub-room SR1 is the control target (n = 1), the variable n is changed from 1 to 2 and the sub-room S
The operation status of R2 is displayed on the display 84 of the main remote controller 81, and the control target of the main remote controller 81 is set to the sub room S
R2 is set (S12), and the process returns to step 2.

When the room switch SW 88 is further pressed from the state where the sub room SR2 is the control target (n = 2), the process proceeds to step 4 because n = 2 in step 3, and the variable n is set to 0. The setting is reset, the operation status of the main room MR1 is displayed (S7), the control target of the main remote controller 81 is set to the main room MR1 (S8), and the process returns to step 2.

In this manner, every time the room switch SW 88 is pressed, the display on the display 84 of the main remote controller 81 is changed to the state shown in FIG.
, The main room MR1 → the sub room S
.., And the room to be controlled by the main remote controller 81 is similarly switched.

For example, when a child or an elderly person who uses the sub-room SR1 forgets to turn off the floor heating and heats the sub-room SR1 where no one is present, the room switching SW8 is used.
In the state where the sub room SR1 is displayed at 8,
When the operation switch 85 of the main remote controller 81 is pressed, the same signal as when the operation switch of the sub remote controller 91 is pressed is transmitted, and the system controller 9 that has received the signal closes the thermal valve 93 of the sub room SR1 to open the sub room SR1. The floor heating operation can be stopped. Similarly, by switching to the display of the sub-room SR2, the floor heating operation of the sub-room SR2 can be stopped.

Similarly, the room to be set is displayed, and the up / down switch 86 of the main remote controller 81 is pressed to adjust the heating set temperature of the room to be controlled. As described above, in the main remote controller 81, the floor heating of the room subjected to the setting operation is switched in conjunction with the display switching of the setting room.

When the up / down switch 86 of the main remote controller 81 is pressed at the same time, the timer operation setting mode is entered, and the operation of turning on / off the floor heating provided in the room to be controlled (the sub room SR1 in FIG. 5) is set. can do. When the timer operation setting mode is entered, the display of “Timer setting” lights up, and “O
"FF" blinks and the operation stop time is adjusted by pressing the up / down SW 86, and the operation SW 85 is pressed to confirm the set time. Next, “ON” flashes, and the operation start time is adjusted by the up / down SW 86 in the same manner.
Pressing the operation switch 85 confirms the set time, ends the timer operation setting, returns to the normal operation, and displays the current time.

By setting the timer for stopping the operation in this way, the operation is automatically stopped after a predetermined time has elapsed without going to the main room MR1 at the time when the floor heating of the sub-rooms SR1 and SR2 is to be stopped. Can be
It is very convenient and economical because it can prevent wasteful operation of keeping the heating on at night. In addition, by setting a timer to start driving, there is no need to go to each room from the early morning and perform driving operation for floor heating operation, adults can sleep well, and families can wake up in a warm room and change clothes Can live a comfortable life. Moreover, since the up / down SW 86 for adjusting the set temperature of the floor heating is also used as a switch for adjusting the timer setting time, the number of components of the main remote controller 81 is reduced, and the cost of the main remote controller 81 is not increased.

According to the hot water supply / room heater 1 of the present embodiment described above, the operating status of floor heating in another room is displayed on the display 84 of the main remote controller 81 by pressing the room switch SW 88 of the main remote controller 81. Therefore, it is possible to grasp whether or not the floor heating of the other room is properly operated without going around each room and staying in the main room MR1.

Further, since the display of the operation status of each room on the display 84 is switched in accordance with the number of times the room switch SW 88 is pressed, the operation is easy. Moreover, even when the number of rooms with floor heating is large, it can be dealt with simply by changing the control program. That is, it is not necessary to provide the operation status display switches in the main remote controller 81 in the same number as the number of the rooms with floor heating, and the manufacturing cost of the main remote controller 81 can be reduced. The display 84 of the main remote controller 81
Since the operating conditions of the sub-rooms SR1 and SR2 are also used for display, large characters can be displayed for easy viewing, and the main remote controller 81 is compact.

Since the rooms to be controlled by the main remote controller 81 are similarly switched in conjunction with the display switching, the floor heating of the sub-rooms SR1 and SR2 is controlled and operated from the main room MR1 in accordance with the operating conditions of each room. Can manage. As a result, waste of floor heating in each room can be eliminated, and energy can be easily saved. In particular,
By pressing the down switch 86D of the main remote controller 81, the heating set temperature of the room to be controlled can be lowered, and by pressing the operation switch 85, the floor heating operation of the room to be controlled can be stopped, While staying in the main room MR1, the floor heating operation of each room can be properly managed, which is very convenient, and the running cost of the hot water supply / room heater 1 can be reduced.

Further, when the operation of the other room is set by the main remote controller 81, the function of the switch is the same as that of the main room MR1 and the setting operation is the same, so that the operation of the other room can be easily set. Moreover, erroneous operation is difficult.

In addition, when the low-temperature radiators 82, 92 and 102 are used, the high-temperature heating water heated by the heating heat exchanger 42 is mixed with the low-temperature heating water radiated by the low-temperature radiators 82, 92 and 102. Then, the low-temperature radiators 82, 92, 10
2 from the heating heat exchanger 42 to the low-temperature radiator 82,
High-temperature heating water does not directly flow into the 92 and 102, and the floor of each room is not overheated.

Since the additional heating of the bathtub water is performed by also using the heating combustion body 60 for the floor heating, the apparatus can be made compact and the manufacturing cost can be reduced. In other words, even when the floor heating is not used, such as in summer, the heating combustion main body 60 is used as a reheating device for the bathtub water, so that it can be effectively used throughout the year.
Therefore, the life of the heating combustion main body 60 is almost the same as the life of the hot water supply combustion main body 70, and replacement can be performed after both the combustion main bodies have been sufficiently used, and there is no waste.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments at all, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention. It is.

Further, all remote controllers in each room may be used as main remote controllers. For example, in a home where only adults live, it is convenient to be able to control the floor heating operation of each room from any room because there is no mischief in the floor heating operation of other rooms. Also, the main remote controller may be provided with only the operation status confirmation function without providing the sub-room floor heating control function. In this case, a person in the room or a person in a nearby room can be contacted with a telephone handset or the like to encourage energy-saving driving, and the structure of the main remote controller is simplified and inexpensive. Also, the floor heating remote control need not have a timer setting function.
