【考案の詳細な説明】
本考案は、ガス器具の種火等を検出してこれを
表示するための熱電表示装置に関する。[Detailed Description of the Invention] The present invention relates to a thermoelectric display device for detecting and displaying a pilot flame of a gas appliance.
従来のガス機器や石油機器の欠点として点火用
種火が見にくいことが挙げられる。特に、密閉式
のガス風呂ボイラや沸し器ではこの傾向が強く、
台所の隅に置かれた場合等においては種火の確認
に非常な不便を強いられている。 One of the drawbacks of conventional gas and oil appliances is that the pilot flame for ignition is difficult to see. This tendency is especially strong in closed gas bath boilers and water heaters.
When placed in a corner of the kitchen, it is very inconvenient to check the pilot flame.
そのために、近年熱電対や光電素子を用いた炎

格となるきらいがあつた。 To this end, flame detection devices using thermocouples and photoelectric elements have been proposed in recent years. However, it is often difficult to directly drive the display means using conventional thermocouples and photoelectric elements, and a transistor amplifier or the like must be used in combination, which tends to complicate the structure and increase the price.
本考案は、上記の点に鑑み、高出力の熱電素子

提供しようとするものである。 In view of the above points, the present invention aims to provide a low-cost thermoelectric display device with a simple configuration that uses a high-output thermoelectric element and directly drives the display device with thermoelectromotive force generated by heat. .
以下、本考案に係る熱電表示装置の実施例を図

They are integrated so that a PN junction 3 is formed, and the parts of the thermoelectric elements 2A and 2B other than the PN junction 3 are insulated from each other by a gap 4 or an isolation member. The low-temperature side end portions of each thermoelectric element body 2A, 2B serve as electrode extraction portions, and electrode leads 5A, 5B, such as thin copper plates, are welded to these portions. The structure in which electrode leads 5A and 5B are provided on the thermoelectric element body 1 is fixed to a heat sink 7 made of copper or the like using an insulating and heat-resistant adhesive 6, and the thermoelectric element 10 is fixed to a heat sink 7 made of copper or the like.
is configured. Electrode leads 5A and 5B of such a thermoelectric element 10 are directly connected to a magnetic indicator 12 through conductive wires 11. This indicator 12 indicates the magnetic core 1
A field coil 14 is wound around the magnetic core 3, and a display disk 15 is pivotally supported between the tips of the magnetic cores.
Permanent magnet 17A symmetrically on the diameter inclined to
17B is fixed, and a spring 18 is used to keep the display disk 15 oriented in a certain direction when not in operation. The display disk 15 has different paint colors on its front and back surfaces, and when the field coil 14 is excited, an N pole and an S pole are formed at the tip of the magnetic core 13, and a permanent magnet 17A with an N pole tip is formed. Then, the display disk 15 is reversed by attracting the permanent magnet 17B whose tip is the S pole.

程度である。 In the above configuration, when the pilot flame 21 of the pilot burner 20 is ignited, the high temperature side end portion (PN junction 3 side) of the thermoelectric element 10 is heated. At this time, since the low temperature side end is attached to the heat sink 7 and remains at low temperature, the thermoelectric element 10 generates a thermoelectromotive force proportional to the temperature difference between the high temperature side and the low temperature side. As a result, the field coil 14 of the display 12 is excited,
The display disk 15 is reversed and changes color, and the pilot flame 21
Display the ignition of. In this case, a thermoelectric element using iron silicide material can generate a voltage of 0.3V between both electrodes of the thermoelectric element at a high temperature of 800°C and a low temperature of 100°C, and the internal resistance of the element at that time is is 11Ω
That's about it.
