BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless communication floor heating control system.

[0002]

2. Description of the Related Art Conventionally, this type of floor heating control system generally uses wired communication. As shown in FIG. 4, a conventional floor heating control system includes, for example, a hot water valve 3 from a heat source unit 1 to four floor heating panels 2a, 2b, 2c, and 2d.
a, 3b, 3c, 3d, hot water outgoing pipes 4a, 4a
b, 4c, 4d are connected, and the hot water return pipe 5 is integrated and connected to the heat source device 1. On the other hand, the floor heating remote controllers 6a, 6b, 6c, and 6d have the floor heating remote controller 6a in the room with the floor heating panel 2a, the floor heating remote controller 6b in the room with the floor heating panel 2b, and the room with the floor heating panel 2c. The floor heating remote controller 6c is attached to the room with the floor heating panel 2d,
The heat source device 1 opens the hot water valve 3a to heat the floor heating panel 2a, for example, in response to a request from the floor heating remote controller 2a. That is, for example, in the case of a heat source device that can connect four systems of floor heating in the heat source device 1, there is always one hot water valve connection terminal that operates in conjunction with one floor heating remote control connection terminal. , These combinations are four sets (however, the number of sets may be any number according to the capability of the heat source device).
It was supposed to be.

[0003]

However, in the conventional floor heating control system, the floor heating remote controller connected to the connection terminal of the hot water valve for controlling the supply of hot water to the floor heating panel and the corresponding floor heating remote control connection terminal. Must be installed in a room with a corresponding floor heating panel. That is, a floor heating remote control 6a must be attached to a room having the floor heating panel 2a, and a hot water valve 3a must be connected to a hot water outflow pipe 4a connected to the floor heating panel 2a. It is very difficult to match the wiring to the hot water pipes and hot water valves buried inside and the wiring to the floor heating remote control for each system as the number of floor heating systems increases, but if this is done, However, if used incorrectly, there is a problem that even if the operation switch of the floor heating remote control is turned on, the floor of the room does not warm up and the floor of the next room warms up, leading to a construction error.

Further, even if a floor heating remote controller of wireless communication is used, it is necessary to set which floor heating remote controller corresponds to which floor heating panel at the time of construction, and if this setting method is complicated, Incorrect settings or forgetting the settings themselves. Then, similarly, even if the operation switch of the floor heating remote controller is turned on, the floor of the room does not warm and the floor of the next room warms, which has the same problem as described above.

[0005]

In order to solve the above problems, the wireless communication floor heating control system of the present invention opens one of a plurality of hot water valves by pressing a test run switch in a heat source unit. The remote control that was able to detect the temperature rise within a certain period of time with the heat-sensitive part inside it, knows the system number of the hot water valve that is currently open by communication from the heat source unit, and stores it in the storage part of this remote control Conversely, the unique number of the remote controller is transmitted to the heat source unit by communication, and the heat source unit stores the received unique number in a storage unit provided therein.

According to the above-mentioned invention, the system of the hot water valve can be automatically stored in the remote controller by pressing the test run switch in the heat source unit, thereby eliminating construction errors such as incorrect wiring and piping and setting errors. it can.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a wireless communication floor heating control system according to a first embodiment of the present invention, and FIG. 2 is a block diagram of one floor heating remote controller.

In FIG. 1, 11 is a heat source unit, 12a, 1
2b, 12c, 12d are floor heating panels, 13a, 13
b, 13c, 13d are hot water valves, 14a, 14b, 14
c and 14d are hot water outgoing pipes. Reference numeral 15 denotes a hot water return pipe, reference numerals 16a, 16b, 16c, and 16d denote floor heating remote controls, reference numeral 17 denotes a test run switch, and reference numeral 18 denotes a nonvolatile memory. And four floor heating panels 12a from the heat source unit 11,
Hot water valves 13a, 13b, 13 are provided for 12b, 12c, 12d.
c, 13d via hot water outgoing pipes 14a, 14b, 14
The hot water return pipe 15 is integrated and connected to the heat source unit 11. In addition, the heat source device 11
Is provided with a test run switch 17 and a nonvolatile memory 18.

For example, one floor heating remote controller 16 shown in FIG.
a includes an operation switch 19a, a room temperature thermistor 20a,
There is a non-volatile memory 21a.

Next, the operation and operation will be described. For example, in the case of a four-floor floor heating system as shown in FIG. 1, when the operation switch 19a of the floor heating remote controller 16a corresponding to the floor heating panel 12a is pressed, the heat source unit 11 receives the signal by a radio wave and receives the signal. The hot water valve 13a in the middle of the hot water outflow pipe 14a connected to 12a is opened to supply hot water to the floor heating panel 12a. Similarly, the floor heating panel 12
b, a combination of a floor heating remote controller 16b and a hot water valve 13b,
Floor heating panel 12c, floor heating remote controller 16c, hot water valve 1
The combination of 3c and the combination of the floor heating panel 12d, the floor heating remote controller 16d, and the hot water valve 13d have the same operation relation. However, the floor heating remote controllers 16a, 16b, 16c, and 16d are identical in appearance except for a unique number stored in advance in a nonvolatile memory (for example, 21a) therein at the factory shipment stage. It must be set as a floor heating remote control for the floor warming panel (hereinafter referred to as address setting). In the present invention,
Provided is a system capable of easily setting an address to the floor heating remote controller.

Now, four floor heating remote controllers which cannot be distinguished from each other are respectively a floor heating remote controller 16a near the floor heating panel 12a, a floor heating remote controller 16b near the floor heating panel 12b, and a floor heating remote controller 16b. Panel 1
2c is the floor heating remote controller 16c, and the floor heating panel 12d is the floor heating remote controller 16d.
And When the test run switch 17 is pressed, the heat source unit 11 first opens the hot water valve 13a, and asks each floor heating remote controller by radio communication at regular intervals whether or not the temperature has risen. The floor heating remote controller 16a, in which the temperature rise was detected within a predetermined time by the room temperature thermistor 20a, responds to the fact that the temperature has risen by radio wave communication, and stores it in the nonvolatile memory 21a in advance at the factory shipment stage. A specific number (for example, 16a in this case) is transmitted. The heat source device 11 that has received this information writes the information, that is, “the hot water valve 13a and the floor heating remote controller 16a correspond” to the nonvolatile memory 18 with the symbol information, for example, “13a⇔16a”. Similarly, for the other floor heating remote controllers, the relative relationship with the hot water valve is stored, and the trial operation is completed.

Next, during normal operation, the floor heating remote controller 16 is used.
a uses the unique number 16a as an address, and when the operation switch 19a is pressed, transmits "16a operation" by radio wave. The heat source device 11 that has received the data compares the data in the nonvolatile memory 18, recognizes that the hot water valve corresponding to the floor heating remote controller 16a is 13a, and opens the hot water valve 13a. Therefore, if the test operation is performed, the address can be automatically set.

(Embodiment 2) The configuration diagram of Embodiment 2 of the present invention is the same as that of FIG. 1, and the configuration diagram of one floor heating remote controller of Embodiment 2 of the present invention is the same as that of FIG. is there.

In the figure, a non-volatile memory 18 in the heat source unit 11 stores a unique number of the heat source unit at the factory shipment stage, and a non-volatile memory 21a in the floor heating remote controller 16a stores what number at the factory shipment stage. I do not even remember. Since the other floor heating remote controllers also do not store anything, the floor heating remote controllers 16a, 16b, 16c, 1
6d has no distinction.

Next, the operation and operation will be described. Heat source machine 1
When the test run switch 17 is pressed, the hot water valve 1
3a, the heat source device unique number (for example, 11) and the hot water valve system number (for example, 13) in the nonvolatile memory 18 are opened.
a) is transmitted to all floor heating remote controllers. Among the floor heating remote controllers that have received this information, the floor heating remote controller 16a, whose temperature rise has been detected within a predetermined time by the room temperature thermistor 20a, responds by radio wave communication that the temperature has risen, The unique number of the heat source device and the system number 13a of the hot water valve are stored in 21a. Next, the heat source unit 11 closes the hot water valve 13a and opens the hot water valve 13b, and similarly, the unique number 11 of the heat source unit and the system number 1 of the hot water valve.
3b is transmitted by radio to all floor heating remote controllers. At this time, the floor heating remote controller 16a whose system number has already been determined will also receive this information, but it will be ignored, and only the floor heating remote controller 16b whose temperature rise has been detected will be the unique number 11 of the heat source unit and the system number of the hot water valve. 13b is stored. Similarly, the system numbers of all the floor heating remote controllers are determined, and the test operation is completed.

Next, during normal operation, the floor heating remote controller 16 is operated.
a uses the system number 13a as an address, and when the operation switch 19a is pressed, the "heat source units 11, 13"
"A driving" is transmitted by radio wave. The heat source unit 11 that receives it
The hot water valve 13a is opened to supply heat to the floor heating panel 12a. Therefore, the address can be automatically set.

(Embodiment 3) FIG. 3 is a block diagram of a wireless communication floor heating control system according to a third embodiment of the present invention. The difference is that the heat source device 11 has a rotary switch 22. As shown in FIG. 3, when floor heating, that is, when the number of connectable hot water valves is four, the rotary switch 22 has a scale from 0 to 4.

For example, as shown in FIG. 3, the number of floor heating systems connectable to the heat source unit 11 is four, but the floor heating panels 12a, 12b, 12c and the hot water valve 13 which are actually connected are connected.
When there are three combinations of a, 13b, and 13c, the scale of the rotary switch 22 is set to 3, and then the test run switch 17 is pressed.

As in the first embodiment, the address is set by opening the hot water valve 13a in order, but since the heat source unit 11 knows that there are only three floor heating panels, the third system address setting is performed. When the test is completed, the test run is completed without going to the next operation. That is, the hot water valve 13d cannot be opened.

[0023]

As described above, according to the first aspect of the present invention, when the test run switch on the heat source unit is pressed, the system number of the floor heating remote controller and the corresponding hot water valve is automatically set in the nonvolatile mode of the heat source unit. Since the data is stored in the memory, an advantageous effect that the address can be automatically set is obtained. Also, even if an operation instruction is transmitted from the floor heating remote controller of the neighbor's house by radio wave, if the transmitted address of the floor heating remote controller is not stored in the nonvolatile memory of the heat source unit, the operation is not started. By doing so, it is possible to prevent malfunction due to the floor heating remote control of the neighbor.

According to the second aspect of the present invention, when the test run switch on the heat source unit is pressed, the unique number of the heat source unit and the system number of the hot water valve corresponding to the floor heating remote controller are automatically set in the floor heating remote controller. , The address can be automatically set. Also, even if an operation instruction is transmitted from the floor heating remote controller of the neighboring house by radio wave, if the transmitted unique number of the heat source device does not match the received heat source device, it is possible to prevent the operation from starting operation. In addition, malfunction due to the floor heating remote controller of the next house can be prevented. In addition, since the unique number of the heat source unit and the system number of the hot water valve corresponding to the floor heating remote controller are stored in the nonvolatile memory in each floor heating remote controller, the storage capacity of the nonvolatile memory in the heat source unit is not large. It has a unique advantageous effect.

In addition, according to the third aspect of the present invention, since the hot water valve to which the floor heating panel is not connected is not opened, in particular, even when the hot water valve is built in the heat source device. There is no accidental accidental water leakage. In addition, the test operation time can be reduced.
