Abstract

PURPOSE:To release the registration of a remote control device, and to attain the registration of another remote controller by deleting all the remote controller ID from the remote controller ID storage means of a water heater which is registered by using a remote controller ID deleting means. CONSTITUTION:At the time of the registration of a remote controller, an ID registration SW 6A is operated, an ID registration mode is set, an ID registration signal to which the remote controller ID is added is transmitted from the remote controller side, and a communication control means 6 writes the received remote control ID in a remote control ID storage means 2 by using a remote controller ID registering means 4. The new remote controller ID is not overwritten on a previously written remote control device ID, but written with it. Then, at the time of registering the remote controller which is used at present in another water heater, an ID delete SW 5a is operated, and a remote control ID deleting means 5 deletes the content of the remote control ID storage means 2. Thus, the entire remote control device ID are deleted from the remote control device ID storage means 2 of the water heater, and the necessary remote controller is registered again.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless remote controller for a water heater, which wirelessly communicates between the water heater and its remote controller (hereinafter also referred to as a remote controller).

[0002]

2. Description of the Related Art A conventional cordless remote control device of this type will be described with reference to FIG.

The cordless remote control device shown in FIG.
Hot water heater control means 1, remote control ID storage means 2 for storing the ID code of a registered remote control, remote control ID reading means 3 for reading the contents of the remote control ID storage means, and remote control IDs for the remote control ID storage means. It is composed of a remote control ID registration means 4 for writing, a communication control means 6 for controlling communication between the remote control and the water heater control means, a communication means 7, and a reception means 8.

When receiving data from the remote controller, the communication control means 6 compares the remote controller ID contained in the data with the remote controller ID stored in the remote controller ID storage means 2, and if they do not match, it is irregular. It is discarded as data, and if they match, it is determined to be regular reception and processing is performed.

When adding a remote controller, the remote controller ID registration SW 6a connected to the communication control means 6 is operated to operate the ID.
After entering the registration mode, the remote controller transmits an ID registration signal with a remote controller ID added thereto, and the communication control means 6 writes the received remote controller ID in the remote controller ID storage means 2 using the remote controller ID registration means 4. This new remote control I
D is not overwritten on the previously written remote control ID, but is additionally written.

It should be noted that, after the remote control ID registration SW 6a is operated to enter the ID registration mode, I
When the D registration signal cannot be received, the communication control means 6 is configured to exit the ID registration mode.

[0007]

However, in the above-mentioned configuration, the ID of the additional remote controller is additionally written instead of overwriting the previously written remote controller ID, so that there is the following problem. It was

For example, a water heater A (not shown) has a remote controller 1
It is assumed that two remote controllers a and a remote controller 1b (both not shown) are registered. In this case, water heater B
Even if the remote controller 1b is reregistered on the side (not shown), the ID code of the remote controller 1b remains in the water heater A as it is. Therefore, if the remote controller 1b is operated, the water heater A will be operated together with the water heater B.

An object of the present invention is to solve the above problems and to delete the contents of the remote controller ID storage means so that the registration of the remote controller which has already been registered can be canceled.

[0010]

In order to achieve the above object, a cordless remote controller of the present invention comprises a water heater controller, remote controller ID memory means for storing a registered remote controller identification number, and the remote controller. Remote control ID reading means for reading the contents of the ID storage means, and remote control ID for writing the remote control ID in the remote control ID storage means
The remote controller includes a registration unit, a remote controller ID erasing unit that erases the contents of the remote controller ID storage unit, a communication control unit that controls communication between the remote controller and the water heater control unit, a transmission unit, and a reception unit. The remote controller ID can be erased from the remote controller ID storage means.

[0011]

According to the present invention, when the remote controller is registered in another water heater with the above structure, all the remote controller IDs are stored from the remote controller ID storage means of the water heater which has been registered by using the remote controller ID erasing means. It is possible to change the registration of the remote controller by deleting it and re-registering the necessary remote controller in the necessary hot water supply device again.

[0012]

Embodiments of the cordless remote control device of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the present invention, in which 1 is a water heater control means for controlling a water heater, 2 is a remote controller ID storage means for storing the ID of a registered remote controller, and a nonvolatile memory. It is composed of Reference numeral 6 denotes a communication control means for transmitting data from the remote controller to the water heater control means 1 and generating data for transmitting the state of the water heater control means 1 to the remote controller, and also for reading the remote controller ID reading means 3
The remote control ID setting means 2 is read and written using the remote control ID registration means 4. 5 is a remote controller ID erasing means, which is I
The D erasing SW 5a and the ID erasing possible mode display means 5b showing the ID erasing possible mode are provided.

To register the remote controller, after operating the ID registration switch 6A to enter the ID registration mode, an ID registration signal with a remote controller ID is transmitted from the remote controller side, and the communication control means 6
Writes the received remote control ID in the remote control ID storage means 2 using the remote control ID registration means 4. This new remote controller ID is not overwritten on the previously written remote controller ID, but is additionally written.

It should be noted that, after operating the remote control ID registration SW 6a to enter the ID registration mode, I
When the D registration signal cannot be received, the communication control means 6 is configured to exit the ID registration mode.

When it is desired to register the currently used remote controller in another hot water supply device, the remote controller ID erasing means 5 erases the contents of the remote controller ID storing means 2 by operating the ID erasing SW 5a.

The operation of the ID erasing means is shown in FIG. To erase the remote control ID, the ID erase SW 5a is continuously pressed. When continuously pressed for 3 seconds or more, the ID erasable mode display means 5b starts blinking. ID erase S during this blinking
When the continuous pressing of W5a is stopped, the remote controller ID erasing means 5 erases the contents of the remote controller ID storing means 2. When the ID erasing SW 5a is continuously pressed for 15 seconds or more, the ID erasing possible mode display means 5b stops blinking and the ID erasing possible mode is exited.

[0018]

As described above, the cordless remote controller for a water heater according to the present invention uses the remote controller ID erasing means when registering the remote controller in another water heater. By deleting all the remote controller IDs from the remote controller ID storage means and re-registering the necessary remote controller in the necessary hot water supply device, the registration of the remote controller can be changed, so that usability is improved.
