本発明は電気ストーブの安全装置を有するストーブに関
するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a stove with a safety device for electric stoves.
従来の技術
従来のこの種の電気ストーブは、第３図、第４図に示す
様に回路的に電源スィッチ１と容量切換えスイッチ２と
転倒スイッチ３とヒータ４とで成っており転倒以外につ
いては何ら安全に対する保証はなかった。又他の機器に
於ても明るさを検知して外燈をオンオフするものがある
が室内で使用する機器については部屋の明るさによって
感度が変わったり誤動作したシする。2. Description of the Related Art As shown in FIGS. 3 and 4, this type of conventional electric stove consists of a power switch 1, a capacity changeover switch 2, an overturning switch 3, and a heater 4. There was no guarantee of safety. There are also other devices that detect brightness and turn on and off outside lights, but for devices used indoors, the sensitivity may change or malfunction depending on the brightness of the room.
特に安全性については強く要求される時代になシ、子供
がガードに手をつっこんで火傷をしたりス″トープ上面
に衣類が落下し火災を起す危険があった。Particularly in an era where safety is highly demanded, there was a risk of children getting burned if they stuck their hands in the guards, or of clothing falling onto the top of the stopper and causing a fire.
発明が解決しようとする問題点
しかし現在、機構的に転倒スイッチを安全装置として採
用する以外には無く、事前に安全を検出することは不可
能と言ってもいいすぎでは無かった。又センサの検出に

るい部屋ではオンしてしまう等の危険性があった。Problems to be Solved by the Invention However, at present, there is no other option than to mechanically adopt a fall switch as a safety device, and it is not too much to say that it is impossible to detect safety in advance. In addition, circuits that operate safely based on sensor detection are being considered, but the sensitivity changes depending on the brightness of the room, so if used in a dark room, the power may malfunction and turn off automatically, or conversely, if used in a bright room, the circuit may malfunction and turn off automatically. There was a risk that it would turn on.
問題点を解決するための手段
そこで上記の様な問題点を解決するために本発明は光を

として構成したものである。Means for Solving the Problems Therefore, in order to solve the above-mentioned problems, the present invention uses two sensors that detect light, one of which detects the brightness of the room, and the other sensor detects the brightness of the room. It is configured as a sensor that detects.
作用 この技術的手段による作用は次の様になる。action The effect of this technical means is as follows.
すなわち、何らかの物体がストーブに接近したシ洗たく
物や衣類等がおおった時に安全装置がすばやく動作する
ため火傷や火災等の事故を事前に防ぐことが出来るもの
である。That is, when some object comes close to the stove and covers washing items, clothing, etc., the safety device operates quickly, making it possible to prevent accidents such as burns and fires.
実施例
以下本発明の一実施例を添付図面にもとづいて説明する
。EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings.
第１図、第２図に於ては電源スィッチ、２は容量切換え
スイッチ、６は本体、ｅは本体５上面に設けられ、部屋
の明るさを検出するセンサ７は物体検出用のセンサで本
体の下面に設けられている。In Figures 1 and 2, 2 is a power switch, 2 is a capacity changeover switch, 6 is a main body, e is provided on the top of the main body 5, and a sensor 7 for detecting the brightness of the room is a sensor for detecting objects, and It is provided on the bottom of the .
交流電源７より電源スィッチ１とリレー接点８と容量切
換えスイッチ２、ヒータ４、転倒スイッチとが直列結線
、れている。A power switch 1, a relay contact 8, a capacity changeover switch 2, a heater 4, and an overturning switch are connected in series from an AC power source 7.
センサ検知回路部については電源７に対して並列に直流
電源回路９がある、直流電源回路９に並列に検出部１ｏ
がありその検出部１０に部屋の明るさを検出するセンサ
６と物体検出用センサ７の出力が入力され、物体の有無
を比較検出する。Regarding the sensor detection circuit unit, there is a DC power supply circuit 9 in parallel to the power supply 7, and a detection unit 1o in parallel to the DC power supply circuit 9.
The outputs of the sensor 6 for detecting the brightness of the room and the sensor 7 for detecting an object are inputted to the detection unit 10, and the presence or absence of an object is compared and detected.
この検出した信号によりリレー１１をコントロールする
ドライバー回路１２があシこれらの組み合せによシ制御
されるものである。The driver circuit 12 that controls the relay 11 is controlled by a combination of these signals.
上記構成により、ヒータ４に電圧を印加中に、本体６の
前面に何らかの物体が近づくと、センサ６．７の出力に
よシ検出回路１０が物体の接近を検知し、ドライバー回
路１２によシリレー１１を動作させ、リレー接点１８で
ヒータ４への通電を遮断する。With the above configuration, if an object approaches the front of the main body 6 while voltage is being applied to the heater 4, the detection circuit 10 detects the approach of the object based on the output of the sensor 6.7, and the driver circuit 12 relays the signal. 11 is operated, and the relay contact 18 cuts off the electricity to the heater 4.

具合さけ無くなり、安全、確実に動作するものである。Effects of the Invention As described above, the present invention efficiently combines two sensors, one sensor detects the illuminance of the room, and the other sensor detects objects, making it possible to detect objects regardless of the brightness of the room. This eliminates problems such as the detection ability changing depending on the brightness, and it operates safely and reliably.
