Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless remote control water heater having a display section for informing a user of a failure in wireless communication between the water heater and the remote controller.

[0002]

2. Description of the Related Art In recent years, remote-control water heaters for transmitting and receiving various kinds of information between a water heater body and a remote control for remote control have become widespread in general households.

A general structure of this conventional remote-controlled water heater will be described with reference to FIG. Water heater main body 14 and a plurality of remote controllers for remote control (hereinafter, simply referred to as remote controllers) 15
Bus connections are made between a, 15b, and 15c with two power cables, and the remote controller 15 is powered by the water heater body 14
Sourced from. The operation state data from the water heater main body 14 and the switch operation data from the remote controllers 15a, 15b, 15c are used as the communication means 16 of the water heater main body 14 and the communication means 17a, 17b, 1 of the remote controllers 15a, 15b, 15c.
7c transmits and receives between the remote controller 15a, 15b, 15c and the water heater main body 14 by superimposing a signal on the power source of the power cable, and the state is indicated by a display unit (not shown) provided on the remote controller side. I was able to confirm it in ().

[0004]

However, in the remote control water heater as described above, the remote controls 15a, 15b, 1
When changing from a wired system in which a bus connection is made between 5c and the water heater body 14 to a wireless system, it becomes inconvenient for usability unless the water heater body side can also confirm whether the transmission and reception were successful. There was a problem.

[0005]

In order to solve the above-mentioned problems, the first means of the cordless remote control water heater of the present invention is to transmit a radio signal from the radio unit to a radio unit attached to the body of the water heater. The water heater main body is provided with a determination unit for determining whether the contents of transmission and reception are coincident with each other and a display unit for displaying when the wireless signal of the contents received from the remote controller is received.

The second means is to equip the water heater main body with a judging means for judging that a communication failure from the remote controller to the water heater main body is not successful and a trouble has occurred and a display section for displaying. .

[0007]

According to the first means of the present invention, the radio unit attached to the water heater main body determines the reception state of the remote controller when transmitting a radio signal from the water heater main body, and displays the radio signal. You can check the transmission status from the main body to the remote control on the water heater main body side.

According to the second means, when a defect occurs in the communication state of the wireless signal from the remote controller,
By displaying a message to that effect on the water heater main body, the state of communication from the remote controller to the water heater main body can be confirmed on the water heater main body side.

[0009]

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

In FIG. 1, 1 is a water heater main body, 2 is a wireless unit, 3 is a transmitting / receiving antenna, 4 is a receiving unit for receiving wireless signals, 5 is a transmitting unit for transmitting wireless signals, and 6 and 7 and 8 are It is a display unit that displays the state of transmission and reception and the content of the failure.

Reference numeral 10 is a remote controller for remotely operating the water heater main body 1, 11 is a transmitting / receiving antenna, 12 is a receiving unit for receiving a radio signal from the water heater main body 1, and 13 is a transmission for transmitting a radio signal to the water heater main body 1. Reference numeral 14 denotes a display unit for displaying a transmission / reception state, and reference numeral 15 denotes a determination unit for determining whether the transmission / reception is correct.

Based on the above configuration, the operation will be described below with reference to FIG. 1 and (Table 1). (Table 1) is a list of respective display methods when transmission / reception is correctly performed.

[0013]

[Table 1]

First, when a wireless signal is transmitted from the transmitter 5 of the water heater main body 1 to the remote controller 10, when it is received by the receiver 11 of the remote controller 10, a confirmation reply or from the transmitter 12 is received. Done. The receiving unit 4 of the water heater main body 1 receives this signal and compares it with the transmission signal from the water heater main body 1,
If they match, the determination means 9 determines that the transmission from the water heater body 1 has been correctly performed, and the display unit 6 is turned on.

When a wireless signal is transmitted from the transmitter 13 of the remote controller 10 to the water heater main body 1, when the wireless signal is received by the receiver 5 of the water heater main body 1, a confirmation reply is transmitted. Done from Part 4. This signal is sent to the remote controller 1
The receiving unit 12 of 0 receives the signal, compares it with the transmission signal from the remote controller 10, and if they match, the determining unit 15 determines that the transmission from the remote controller 10 has been correctly performed, and the notification signal from the transmitting unit 13 To send. When the receiving unit 4 on the water heater main body 1 side receives this notification signal, the determination unit 9 determines that the communication from the remote controller 10 to the water heater main body 1 has been correctly performed, and lights the display unit 7.

Table 2 is a list of display methods when a defect occurs.

[0017]

[Table 2]

First, when a radio signal is transmitted from the transmitter 4 of the water heater main body 1 to the remote controller 10, the contents input from the control circuit (not shown) of the water heater main body 1 to the transmitter 4 are transmitted. When the determination means 9 determines that the contents of the signals do not match, the display unit 6 and the display unit 8 are blinked to notify that the transmission from the water heater body 1 is defective.

Further, even when the transmitted signal and the input content match, if the determination means 9 determines that the content of the reply signal from the remote controller 9 and the content of the transmission signal from the water heater body 1 do not match, the display is made. The part 6 and the display part 7 are made to blink to inform that the reception of the remote controller 9 is defective.

When a radio signal is transmitted from the transmitter 13 of the remote controller 9 to the water heater body 1, the remote controller 9
When the determination unit 15 determines that the input content from the operation unit (not shown) of the above and the content of the transmitted signal do not match, the transmission unit 13 transmits a signal notifying that, and the reception unit 4 of the water heater body 1 When it is received, the display unit 6, the display unit 7, and the display unit 8 are blinked to notify that the remote control transmission is defective.

[0021]

As is apparent from the above description, according to claim 1 of the present invention, it is confirmed by the state of the display section of the water heater main body that the transmission of the radio signal from the water heater main body to the remote controller is correctly transmitted. it can.

According to the second aspect, if there is a problem in transmitting a wireless signal from the remote controller to the water heater body, it can be confirmed by looking at the display state of the display unit of the water heater body.
