2. Description of the Related Art Japanese Patent Laid-Open Publication No. Hei 2-115901 and Japanese Utility Model Laid-Open Publication No.
There is an invention and a device disclosed in JP-A-43086.

The remote controller system disclosed in Japanese Patent Application Laid-Open No. 2-115901 discloses an input means for setting an arbitrary password, a storage device for storing the input password, and transmitting the stored password and control code. A receiving unit including a remote controller having a transmitting device, input means for setting an arbitrary password, a storage device for storing the inputted password, and a device for determining a password in a transmission code sent from the remote controller. ing.

The same password can be set on the remote controller side and the receiving unit side, and transmission, reception, and reception code discrimination processing of the password are performed to prevent transmission code interference and prevent malfunction of the device body. Can be.

The remote control device disclosed in Japanese Utility Model Laid-Open Publication No. 2-43086 automatically transmits a random number ID code from a transmitter, and the receiver stores the ID code before receiving the ID code. The ID code is reset, the new ID code is stored, the ID code is collated when a normal control signal is transmitted from the transmitter, and the control device is driven based on the control signal when they match. It was made.

[0006] Since the transmitter automatically transmits the ID code of the random number, it is easy to set the ID code on the transmitting side, and when the ID code is received by the receiver, the ID stored beforehand is stored. Since the code is reset and the new ID code is stored, the setting of the ID code on the receiving side can be easily performed, and an easy-to-use remote control device can be obtained.

[0007]

The conventional remote controller system as described above enables the same password (ID code) to be set on the remote controller (transmitter) side and the device main body (receiver) side, and the remote controller system uses the same password. Since the device main body is driven when the sent password matches the password of the device main body, erroneous operation of the device main body can be prevented. However, if the remote control breaks or is lost, for example, the password is set again with the new remote control.However, it is highly likely that the same password as the previous remote control is set, and if the same password is set, the lost remote control will be lost. When found, both the old and new remotes will be available,
There is a risk that both will operate the device main body, and the safety and reliability of the device main body will be reduced.

[0008] Even if an ID code is generated by a random number, a different ID code is not always generated and set, and different ID codes are all set as the remote controller is exchanged a plurality of times. It becomes difficult, and when there is a remote controller having an ID code used once, there is a possibility that the device main body may malfunction.

In particular, since a water heater is a combustion device and is required to be highly safe because it is a combustion device, if a lost remote control is effective and usable, operations such as a burning operation by the remote control are performed. There was a big problem such as the possibility of the water heater becoming lacking and the possibility increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. A system ID is constituted by a remote controller ID number and the like, and the system ID is registered or updated in the latest remote controller and the water heater main body. It is an object of the present invention to provide a water heater in which the use of a previous remote controller can be invalidated and only the latest remote controller can be used.

And other storage means 48 for storing data other than those described above.
It consists of

The remote controller controller 40 controls the wireless communication means 31 in the same manner as the wireless communication control means 21 in the water heater main body 1 and the wire communication control means 22 in the water heater main body 1 as well. A wire communication control means 42 for controlling the wire communication means 32, and a water heater ID number transmitted from the water heater body 1 when the system ID of the water heater body 1 is registered or updated, together with an ID number of the remote controller. The system comprises a system ID registration unit 43 to be stored in the ID storage unit 47 and another control unit 44 for controlling operations of the remote controller other than those described above.

The configuration of various remote controllers such as the main remote controller 3 is the same as that of the remote controller 2. The remote controller ID number storage means 46 of the remote controller side storage means 45 stores, for example, N _M1 , The sub remote controller 4 is N _A1 , the main sub remote controller 5 is N _B1, etc.
Remote control ID numbers corresponding to various remote controls are stored in advance.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. First, in the water heater main body 1 before the water heater is shipped and the system ID is registered, the water heater ID number “N _H1 ” is stored in the water heater ID number storage means 26 in advance, and FIG. As shown,
“N _H1 ” is stored in the area of the water heater ID number of the system ID in the system ID storage means 27, and a dummy number “N ₀ ” is stored in each remote control ID number area. On the other hand, the remote controller ID number storage means 46 on the remote controller side previously stores the remote controller ID number of each remote controller (for example, "N _F1 " in the remote controller 2).

Next, for example, when registering or updating the system ID in the flow remote controller 2, the wired communication means 32 of the flow remote control 2 and the wired communication means 12 of the water heater main body 1 are connected by a dedicated wired cable 51. The wired communication means 12 and 32 respectively detect the connection of the wired cable 51 (S1 and S2). If the connection is not detected, both the water heater main body 1 and the flow remote controller 2 wait for the connection of the wired cable 51. Becomes

Next, when the connection of the wired cable 51 is detected, the remote control ID number "N _F1 " stored in the remote control ID number storage means 46 from the connected remote controller 2 is transmitted to the wired communication means 32, The water heater main body 1 is transmitted to the water heater main body 1 via the cable 12 and the cable 51 (S3), and the water heater main body 1 receives the remote control ID number "N _F1 " by the wire communication means 12 (S4, S5). Next, the system ID updating means 23 receives the received remote control ID number “N _F1 ”.
Selects an ID number area corresponding to the remote control type in the system ID of the water heater main body 1 according to the received remote control ID number “N” in the selected ID number area.
_F1 ”and register the system I as shown in FIG.
D is created (S6). When the system ID is created, the water heater ID number “N _H1 ” is transmitted to the remote controller 2 by the wired communication means 12 and the like (S
7), storing the created system ID in the system ID storage means 2
7 (S8).

On the other hand, the remote controller 2 has a wired cable 5
Water heater ID transmitted from water heater main body 1 via
Upon receiving the number "N _H1 " (S9, S10), the system ID registration means 43 causes the remote controller ID number "N _H1 " of its own.
_F1 ”and this water heater ID number“ N _H1 ”
It is stored in the D storage means 47 (S11). At this time, the dummy number “N ₀ ” is stored in the ID number area of the other remote controller, and the one stored in the system ID storage means 47 is the common system ID between the water heater main body 1 and the remote controller 2. Becomes Then, the completion of the registration or update of the system ID is displayed by the output means 34 (S1).
2).

Next, after confirming registration or update of the system ID, the wired cable 51 or
Is removed, and the connection of the wired cable 51 is detected by the wired communication means 12 and 32 (S13 and S14). If the connection is not detected, the operation of registering or updating the system ID is completed, and the flow to the water heater main body 1 is terminated. The remote controller 2 can be operated by wireless communication.

Thereafter, also in the case of various remote controllers such as the main remote controller 3, a series of operations similar to the above are performed, and FIG.
As shown in (d), the system ID of the water heater main body 1 is registered or updated. At this time, the dummy number “N ₀ ” is still set in the remote control ID number area corresponding to the remote control that is not set. Also, for example, the remote controller 2 (own remote controller ID number “N _F1 ”) is lost, and the same type of remote controller (own remote controller ID number “N _F1 ”) is lost.
_When the system ID is updated by newly setting " _F2 "), the same series of operations as described above are performed. In this case, as shown in FIG. 2E, the remote control ID number area of the flow remote control 2 is updated from "N _F1 " registered previously to "N _F2 ". As a result, even if the water heater ID number of the system ID is the same, the remote controller ID number is always different, so that the same system ID as before is not set, and a lost remote controller is found and two remote controllers of the same type are found. The latest remote control only this system I
Since D coincides with D, operation of the water heater main body 1 by two or more remote controllers of the same type can be prevented.

Next, the remote radio operation by each of the remote controllers 2, 3,... Of the water heater main body 1 after the system ID is registered or updated will be described with reference to the communication polling timing chart of FIG. 4 and the flowchart of FIG. .

FIG. 4 shows a water heater main body 1 and remote controllers 2, 3,.
In the polling timing chart of the communication between the wireless communication device and the wireless communication device, the transmission and reception timings are controlled by the polling timing, and are controlled by the wireless communication control unit 21 of the water heater main body control unit 20 of the water heater main body 1. In the figure, the first half of the polling cycle is the water heater main body system data transmission time KT1 and the remote control system data reception time RT1, and the second half of the polling cycle is the water heater main body system data reception time KT2 and the remote control system data. The transmission time is RT2. The remote-control-side system data transmission time RT2 is divided into slots 1, 2, 3, and 4.
Is the remote controller 2, slot 2 is the main remote controller 3,
Each slot is assigned to each remote controller. And the order of the slots that return a response to the water heater body 1 is
Download data and system ID from water heater 1
Is determined by the order in which the combined system data is sent, and this order is rotated every polling so that slot 1 is always assigned once every four times so that a uniform response can be made to any remote controller. It has become. Further, the water heater main body 1 recognizes which slot is used to return a response from which remote controller in the water heater main body side system data reception time KT2.

First, when the polling timing becomes the transmission timing of the water heater main body 1 (system data transmission time KT1 of the water heater main body) (S21), the water heater main body 1 downloads the data, the water heater ID number, and the ID of each remote controller. .. Are combined to form system data, and this system data is used for each remote controller 2, 3,.
Are transmitted one after another (S22). The download data of the system data is extracted from the other storage means 29 of the water heater main body storage means 25, the system ID is extracted from the system ID storage means 27, and each remote controller 2 is transmitted from the wireless communication means 11 via the antenna 11a. 3. Sent to the side. The water heater body 1 is then in a standby state for receiving a response from each of the remote controllers 2, 3,..., And the water heater body 1 receives a response from each of the remote controllers 2, 3,. Wait (S23).

On the other hand, the remote controller receives the system data from the water heater main body 1 by the wireless communication means 31 (S24).
Thereby, the system data reception time RT1 on the remote controller side
And the remote controller side system data transmission time RT2. At the same time, the system ID is extracted from the system data by the wireless communication control unit 41 of the remote control unit 40, and the water heater ID number of the system ID is stored in the remote control storage unit 45.
The water heater ID number of the system ID stored in the system ID storage means 47 is checked (S25).
If they do not match, the remote control returns to the system data reception waiting state (S24). System I if matched
It is determined whether or not the remote controller ID number set in D includes its own remote controller ID number (S26).
If there is no D number, the remote control returns to the system data reception waiting state (S24).

If you have your own remote control ID number,
The download data is stored in the other storage means 48 of the remote controller side storage means 45 (S27), and output such as display is performed by the output means 34 based on the download data (S28). At this time, if a new operation occurs from the remote controller side, the water heater main body 1 is notified (S29, S30),
If there is no operation on the remote controller side, the process returns to a state of waiting for receiving system data from the water heater main body 1 (S29, S24).

Here, since the response slots for the instructions from the remote controllers 2, 3... To the water heater main body 1 are determined for each remote controller type, the slots corresponding to the remote controllers (slots 1 to 4) Instruction data must be transmitted at the timing of any one of them). In order to update the information of the hot water supply control unit 13 as soon as possible, the polling cycle needs to be shortened as much as possible. The response of the main body 1 is only one remote control.

For example, when transmitting instruction data from the remote controller 2 to the water heater main body 1, the remote controller 2 first transmits another remote controller (for example, the main remote controller 3) in the previous slot immediately before the slot of the remote controller 2. Whether the operation is performed is detected by the wireless communication means 31 and the wireless communication control means 41. If the previous slot is used, the transmission to the water heater main body 1 is waited until the next polling timing. If not used, the wireless communication control means 4
1 extracts the system ID from the system ID storage means 47 and transmits it together with the instruction data from the wireless communication means 31 to the water heater main body 1 (S30). Note that the other remote controllers also perform transmission to the water heater main body 1 in the same manner.

When the water heater main body 1 receives instruction data from one remote controller during the water heater main body side system data reception time KT2 (S23), the system ID of the received data is received.
Is extracted by the wireless communication control means 21 and the group of the water heater ID number of the system ID and the ID number of the remote controller stored in the system ID storage means 27, the water heater ID number of the system ID from the remote controller side, and the remote controller of its own The ID number is collated with the ID number (S31). And both water heater ID
If the numbers and the remote controller ID numbers match and the response slot matches, the received data is stored by the other storage means 29 (S32), and hot water supply control corresponding to the received data is performed (S33). Then, it waits for the next polling timing (S21).

Further, the remote controllers 2 and 3 are provided to the water heater main body 1 within the system data reception time KT2 of the water heater main body.
If no transmission of instruction data or the like has been transmitted from... At the transmission timing of the next polling timing (S23, S21...), And when the transmission timing (water heater main body side system data transmission time KT1) comes,
Download data and system I to each remote control 2,3 ...
D and transmits a series of operations similar to those described above.

As described above, the system ID used for the wireless communication between the water heater main body 1 and each of the remote controllers 2, 3... Is set as the system ID. For example, if the remote controller previously used is lost and found, even if the user tries to operate the water heater main body 1 with the remote controller, the system ID of the water heater main body 1 side is set.
Since the remote control ID number corresponding to the remote control type differs from the remote control ID number of the system ID on the remote control side, the remote control previously used is invalidated, and only one remote control (latest remote control) is always used and valid.
The operation of the water heater main body 1 by the same type of remote controller can be prevented.

In the above embodiment, the case where the configuration of the system ID on the remote controller side is the same as the configuration of the system ID on the water heater main body side has been described.
May be composed of a water heater ID number and its own remote control ID number. Also, a case has been described in which the present invention is implemented in a water heater in which a plurality of types of remote controllers correspond to one water heater main body. However, the present invention is also applied to a water heater in which one remote controller corresponds to one water heater main body. The present invention may be implemented, and in this case, a similar effect is obtained.
