DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a system configuration diagram of a hot water floor heating apparatus according to the present invention, and FIG. 2 is a control block diagram, which will be described below. First, 1 is installed outdoors and is a heat source machine that incorporates a heat exchanger 2 that burns gas, oil, etc. and is heated by the combustion heat, and 3 is installed in a living room with hot water piping. 4 and 5 are pipes for circulating hot water between the heat source unit 1 and the floor heating panel 3, and 6 is a pipe between the heat source unit 1 and the floor heating panel 3. 5 is a circulating pump, 7 is a bypass pipe, 8 is a thermal valve that is a flow rate adjusting valve, 9 is a control panel on which a microcomputer (hereinafter referred to as “microcomputer”) 37 is arranged, 10 is a user A remote controller (remote controller) 11 for controlling the heat source unit 1 operated by the control unit 11 is installed on the wall surface of the room and receives a control signal from the remote controller 10 wirelessly (infrared) to receive the heat source In order to communicate to machine 1 It is a vessel.
[0009]
Next, the remote controller 10 will be described in detail. The remote controller 10 is provided with a microcomputer 20. The microcomputer 20 has a display unit 21 for displaying a set temperature, time, etc., an operation switch 22, a set temperature. The key input unit 25 such as the temperature lowering switch 23 and the temperature rising switch 24 used when setting the temperature, the infrared light emitting unit 26 for transmitting the command by the operation of the key input unit 25 to the repeater 11, etc. are connected. The
[0010]
The repeater 11 will be described in detail. The repeater 11 is provided with a microcomputer 27. The microcomputer 27 is a room temperature detection thermistor which is a room temperature detection sensor for detecting the temperature of the room where the floor heating panel 3 is installed. 12. Control signals from a display unit 29 having an operation display lamp 28 that is lit during operation, a test operation display lamp 35 that is lit during a test operation, a key input unit 31 such as an operation switch 30, and the infrared light emitting unit 26. An infrared light receiving unit 32 for receiving light, a control circuit received by the infrared light receiving unit 32, a command by operating the key input unit 31, and the like are connected to the heat source unit 1 via the communication line 34, etc. Is done.
[0011]
The set temperature data set by the user by operating the setting means such as the temperature drop switch 23 and the temperature rise switch 24 of the remote controller 10 is stored in the storage unit in the microcomputer 20 and the infrared light emitting unit 26 emits light. As a result, the infrared light receiving unit 32 receives light and is also stored in the storage unit in the microcomputer 27. The microcomputer 27 controls the heat source unit 1 based on the deviation between the room temperature data detected by the room temperature detection thermistor 12 and the set temperature data set by the user and stored in the microcomputer 27.
[0012]
A microcomputer 37 is mounted on the control panel 9 of the heat source unit 1, and the microcomputer 37 includes a communication circuit 38 connected to the communication circuit 33 of the repeater 11 via the communication line 34, the circulation pump 6, A drive circuit 39 for driving the thermal valve 8 and a combustion control circuit 40 for controlling the gas valve 42 and the igniter 43 are connected.
[0013]
With the above configuration, the normal operation of the hot water floor heating apparatus is performed as follows. First, when the user operates setting means such as the temperature lowering switch 23 and the temperature raising switch 24 of the remote controller 10, the set temperature data is stored in the storage unit in the microcomputer 20 and the infrared light emitting unit 26. Is received by the infrared light receiving unit 32 and stored in the storage unit in the microcomputer 27.
[0014]
When the operation switch 22 of the remote controller 10 is operated, the microcomputer 20 causes the infrared light emitting unit 26 to emit light so as to start the operation of the hot water floor heating apparatus, and outputs a control signal. Accordingly, since the infrared light receiving unit 32 of the repeater 11 receives the light, the microcomputer 27 controls the communication circuit 33 to output a control signal via the communication line 34. Since this control signal is input to the communication circuit 38 of the heat source unit 1, the microcomputer 37 controls the gas valve 42, the igniter 43, etc. via the combustion control circuit 40 and the circulation pump 6 or the like via the drive circuit 39. The thermal valve 8 and the like are controlled to start combustion.
[0015]
Accordingly, the hot water circulates between the heat source unit 1 and the floor heating panel 3 through the hot water circulation pipes 4 and 5 by the circulation pump 6, but the room temperature data detected by the room temperature detection thermistor 12 and the user The microcomputer 27 controls the heat source unit 1 based on the deviation from the set temperature data set and stored in the microcomputer 27. That is, the microcomputer 27 calculates the ON time and the OFF time of the thermal valve 8 based on the deviation between the set temperature and the room temperature, and controls it via the microcomputer 37, so that the amount of hot water supplied to the floor heating panel 3 is controlled. It is controlled so that the room temperature becomes the set temperature.
[0016]
Thus, since the repeater 11 which received the control signal from the remote controller 10 by radio (infrared) is configured to transmit the heat source unit 1 to the heat source unit 1, the heat source unit is connected to the pipe shaft, for example, in an apartment house. Even when placed in a space surrounded by, for example, the control signal can be reliably transmitted to the heat source unit 1. In addition, when the room temperature detection thermistor 12 is provided in the remote controller as in the prior art, there is a problem that the room temperature cannot be detected reliably when the remote controller is placed on the floor heating panel 3. Since the detection thermistor 12 is provided in the repeater 11 installed on the wall surface of the room, the room temperature can be reliably detected.
[0017]
The normal operation is similarly started by operating the operation switch 30 of the repeater 11, but is omitted here.
[0018]
Next, an embodiment in which the repeater 11 is housed in a wiring box 50 compliant with Japanese Industrial Standards embedded in the wall surface of the room will be described with reference to FIG. First, 51 is a box body embedded in the wall of the room, 52 is fixed to the box body 51 with screws 53 in a state where the repeater 11 is placed in the middle and the mounting holes 51A and 52A are aligned. A mounting bracket 54 is an intermediate frame fixed by screws 55 in a state where the intermediate portion is pulled out and the mounting holes 52B and 54A are aligned with each other, and 56 is a mounting in a state where the repeater 11 is placed in the intermediate portion. The bracket 52 is a plate that is fixed to the box body 51 and is fitted to cover the inner frame 54 that is fixed to the mounting bracket 52. The operation switch 30 and the display unit 29 of the repeater 11 are attached to the plate 56. A window frame 56A is opened so that can be seen.
[0019]
Therefore, by placing the repeater 11 in the wiring box 50 compliant with the Japanese Industrial Standard, it can be installed on the wall surface of the room without a sense of incongruity, and the repeater 11 can be installed without impairing the finished state of the room. .
