Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open combustion appliance having a wireless remote control.

Conventional technology Conventionally, full-scale wireless remote control devices have not been realized from the viewpoint of safety in open-type combustion appliances, but with recent advances in control technology and improved reliability of remote control, shutdown and temperature Wireless remote controls have been embodied exclusively in adjusting settings.

Problems to be Solved by the Invention In the above-described conventional wireless remote control device, only the operation of stopping the operation of the appliance and adjusting the temperature setting can be performed, which is inconvenient. In addition, the apparatus has a transmission / reception function in that the number of functions is small, and the cost is high.

The present invention has been made in view of the above-described problems, and while maintaining safety of an appliance, operation / stop of an appliance by a wireless remote control device,
It is an object of the present invention to provide a safe, reliable, and inexpensive wireless remote control open type combustion appliance with abundant functions enabling timer reservation operation.

Means for Solving the Problems In order to achieve the above object, a wireless remote control open-type combustion appliance of the present invention includes a transmission unit having a transmission circuit for outputting a signal for controlling the open-type combustion appliance by a key operation, and a transmission unit. Light receiving means for receiving the modulated signal, decoding means for converting the modulated signal into a pulse code string, data decoding means for decoding the pulse code string and outputting an output signal based on the signal content from the transmitting means, Reads a plurality of photocoupler means operated by an output signal from the data decoding means, a plurality of key switch means of an instrument main body configured in parallel with an output section of the photocoupler means, and a switching operation of the key switch means or the photocoupler means. A microcomputer for executing a predetermined control operation, and an operation based on an output signal from the microcomputer. Operation content display means, fuel control means for fuel supplied to the burner,
It is configured to include an igniting unit for fuel and a blowing unit for exchanging heat of combustion heat and blowing it out as hot air.

According to the present invention, the microcomputer receives both the operation by the plurality of key switch means of the appliance main body and the signal from the wireless remote control device as the same operation signal by the above-described configuration, and thus the basic safety of the open-type combustion appliance. Wireless remote control operation while maintaining the performance.

An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a transmitting means having a built-in transmitting circuit for outputting a signal for controlling an open-type combustion appliance by a key operation;
2 is a light receiving means for receiving the signal transmitted from the transmitting means 1; 3 is a decoding means for converting the modulated signal received by the light receiving means 2 into a pulse code train; A data decoding means for outputting an output signal based on the signal content from 1 is a phototransistor, and 5 is a phototransistor. The output signal from the data decoding means 4 turns on / off a current flowing through the photodiode to turn on the output transistor.
/ OFF. Although omitted in the drawings, a plurality of phototransistors are provided for each operation. Reference numeral 6 denotes a microcomputer, which is a so-called one-chip microcomputer having a CPU, a ROM, a RAM, and an input / output unit, in which an operation sequence of the open-type combustor is programmed and incorporated. Reference numeral 7 denotes a key switch, similar to the phototransistor 5, which is provided in plural for each operation content. 8 is an inverter IC, 9 is a current limiting resistor, 10 is a diode, 11 is operation content display means,
Reference numeral 12 denotes fuel control means for supplying fuel to the barter, reference numeral 13 denotes ignition means for fuel ejected from the burner, and reference numeral 14 denotes air blowing means for blowing air that has exchanged heat with combustion heat as hot air. And
The components indicated by the reference numerals 2 to 14 are the main body of the hot air blower.

Next, the operation will be described. When the key switch 7 corresponding to the operation switch is pressed, a current flows from Vdd to the inverter IC 8 through the resistor 9, the key switch 7, and the diode 10 when the scan output of the microcomputer 6 becomes high. When the LO signal is input to the KEY input, the microcomputer 6 determines that the operation switch has been pressed, and determines that the fuel control means 12, the ignition means 13,
The operation of the blowing means 14 is controlled according to a predetermined program.
The operation state is displayed by the operation content display means 11. Next, when a key corresponding to the operation switch provided on the transmitting means 1 is pressed, a signal is transmitted through the light receiving means 2, the decoding means 3, and the data decoding means 4, and a current is supplied from Vcc to the emitting diode of the phototransistor 5. The output transistor of the flow phototransistor 5 is turned on. As a result, the microcomputer 6 determines that the key switch 7 has been pressed, and starts operation control of the appliance.

Similarly, for the timer reservation operation, the operation stop operation, the temperature adjustment UP / DOWN operation, the re-start operation, the sleep timer operation, etc., the corresponding key switch 7 on the appliance side or the key switch on the transmission means 1 side is operated. This allows operation control.

 Next, measures against a malfunction will be described.

Since the transmitting means 1 is small and lightweight and easy to carry, it is often placed at hand and handled casually, so that the operation of the appliance does not start even if the key switch corresponding to the operation switch is touched by mistake. A plurality of key switches corresponding to the switches are provided, and an operation signal is transmitted by simultaneously operating the plurality of key switches.

The timer reservation operation is programmed in the microcomputer 6 so as to be accepted from during the operation of the appliance, and the timer reservation operation signal is transmitted by simultaneously operating a plurality of key switches as in the case of the operation switch, so that the timer reservation is performed. Make sure you do n’t accidentally type it.

Further, when the operation of the appliance is started by the transmission means 1, a program is programmed in the microcomputer 6 so that the operation is automatically stopped after a limited time so that even if the operation is forgotten, the fire is automatically extinguished and the operation is stopped. .

Effects of the Invention As is clear from the above embodiments, according to the present invention, the microcomputer accepts both the operation by the plurality of key switch means of the instrument body and the signal from the wireless remote control device as the same operation signal, An abundant, safe, reliable and inexpensive wireless remote control open combustion device can be provided.
