Abstract

<P>PROBLEM TO BE SOLVED: To prevent undesired start of combustion caused by incorrect operation, dropping of article, or the like, in a remote control device capable of instructing the start of combustion from a place separating from a heater main body. <P>SOLUTION: The heater main body 1 and the remote control device 7 for transmitting a control signal to the heater main body 1 by infrared ray radiation are provided, the remote control device 7 has a pair of electrodes 9 on its surface touched by a hand, a timer means 8 counts a prescribed time on the basis of the detection of electric continuity of the electrodes 9, and an operation start signal is transmitted by the operation of an operation switch 10 within the prescribed time. As the remote control device 7 is kept in an operation start signal standby state only by being unconsciously held by a hand to operate the remote control device 7 without complex operation while preventing incorrect operation, and the operation start signal is transmitted only by operating the operation switch 10 as it is, the convenience can be improved, which improves its usability. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a control device for a heating appliance called an FF stove or a fan heater.

Conventionally, in this type of device, a wireless remote control device is provided so as to control the heater body even from a location away from the heater body, and the convenience in use thereof is measured. Is equipped with a lock switch so that only the fire extinguishing instruction can be accepted by turning on the lock switch. It was intended to prevent danger from being pressed. (For example, refer to Patent Document 1.)
No. 1-25240

  By the way, with this conventional device, even if a lock switch is provided, it cannot be locked unless this switch is turned on. Therefore, the above-mentioned danger cannot be reliably prevented, and particularly the combustion of the heater body starts. Since the remote control device is also equipped with an operation switch that allows the user to burn without knowing that the child has been mischievous or when a pet or object has fallen, or when the user has not intended it, In addition to wasting fuel, unmanned combustion has the problem of leading to major disasters such as fires.

  The present invention pays attention to this point and solves the above-described drawbacks. In particular, the configuration includes a heater main body and a remote control device that transmits a control signal to the heater main body by infrared rays. The remote control device is touched by a hand. A pair of electrodes are provided on the surface, the timer means starts counting for a predetermined time when the continuity of the electrodes is detected, and an operation start signal is transmitted when the operation switch is operated within the predetermined time.

  According to the present invention, since the operation start signal is not transmitted unless two operations are always performed, the combustion is performed even when there is no person or the user does not intend due to the mischief of the child or the fall of the pet or the object. It can be used with peace of mind without incurring the danger that it will start, and it can be used with peace of mind to operate the remote control device without being forced to perform complicated operations while preventing misoperation. If the operation start signal is in a standby state and the operation switch is operated as it is, the operation start signal is transmitted, so that the convenience is extremely improved and the usability is good.

Next, a controller for a heating appliance according to the present invention will be described with reference to a preferred embodiment shown in the drawings.
Reference numeral 1 denotes a fan heater which has a burner portion inside and heats combustion heat as it is by blowing air from a convection fan (not shown) provided on the back surface, and discharges it from the hot air outlet 2 to heat the room. It is the main body of the heater that is said to be a heater.

  3 is a display unit provided on the upper surface of the heater body 1 and includes a receiving unit 4 for receiving an infrared signal, a lamp group 5 for displaying various operating states, a room temperature, a set temperature, and a timer time. And a digital display 6 for switching display.

  7 is a card-type remote control device that is equipped with a plurality of push-type switches and emits infrared signals from a place away from the heater main body 1 to control it. The pair of electrodes 9 that hold in a standby state in which the timer means 8 starts counting and can output an operation start signal for a predetermined time of 3 seconds, and the heater main body 1 is pressed in this standby state. The operation switch 10 that outputs an operation start instruction signal to the heater main body 1 and outputs the operation stop signal when pressed again, and a three-hour timer that automatically extinguishes fire after three hours from the operation start. Extension switch 11, ignition timer for automatically starting operation after a set time- timer switch 12 for performing operation, timer-time and setting temperature adjustment up / down switch 13 14 is provided.

  Next, the electric circuit diagram shown in FIG. 4 will be described. Reference numeral 15 denotes a microcomputer (hereinafter referred to as a microcomputer) having a memory means, a calculation means, a timer means by counting, a determination function, etc. A receiver 4 and a room temperature sensor 16 comprising a thermistor for detecting the room temperature are connected to the input side, and the lamp group 5 and the digital display 6 and the heater body are connected to the output side. 1 drive circuit 17 is connected.

  18 is a sub-control device comprising a microcomputer with built-in timer means 8 provided in the remote control device 7. On the input side is a pair of electrodes 9, operation switch 10, extension switch 11, timer switch 12, adjustment up, Down switches 13 and 14 are provided, and a transmitter 21 that emits an infrared signal via the switching element 20 is provided on the output side. The sub-control device 18 determines the pressing of each switch, and the standby state and control signal are determined. Is input to the main controller 15 via the transmitter 21 to perform various operation controls.

  After the 3-second standby state of the operation start signal has elapsed, the timer means 8 is cleared and the operation start signal output instruction by the operation switch 10 is invalidated, and the remote control device 7 and the heating appliance body 1 If a display such as a lamp for indicating the standby state is provided on either of them, the reason why the operation start instruction signal is not received is distinguished from the reason that the remote control device 7 is caused by other reasons such as power off. It becomes convenient to use.

  In addition, the pair of electrodes 9 uses a human body that conducts a minute current and is a conductor. However, the present invention is not limited to this. For example, a change in capacitance or a change in resistance value can be detected. May be detected.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG.
When the heater main body 1 is stopped, holding the remote control device 7 for hand operation makes the pair of electrodes 9 conductive with the hand as a conductor (step 22). In step 24, it is determined whether or not a predetermined time of 3 seconds has elapsed. In step YES, it is cleared in step 25. In NO, it is determined in step 26 whether the operation switch 10 is pressed during standby. If it is seen and pressed, the control unit 7 outputs an operation start signal from the remote control device 7 to the heater body 1 in step 27, and the heater body 1 starts combustion and performs the heating operation.

  Therefore, the operation start of the heater body 1 can be operated with the remote control device 7 from a position away from the appliance, which is very convenient. Further, if the operation start signal is not necessarily operated twice, the operation start signal is Since it is not transmitted, there is no danger of starting combustion even when there is no person or the user does not intend due to mischief of a child or the fall of a pet or an object, and it can be used with confidence. Yes, in order to operate the remote control device without having to consciously operate it while preventing misoperation and holding it by hand, it becomes a standby state of the operation start signal by holding it by hand, and if you operate the operation switch as it is, you can operate Since the start signal is transmitted, the convenience is extremely improved and the usability is good.
