本考案は、正の抵抗温度係数を有するチタン酸
バリウム系半導体磁器発熱体（以下正特性磁器発

方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating device using a barium titanate semiconductor ceramic heating element having a positive temperature coefficient of resistance (hereinafter referred to as a positive characteristic ceramic heating element) and a method for manufacturing the same.
正特性磁器発熱体は、周知のように、特定温度

ロム発熱体と違つて過熱の危険がなく、安全で信
頼性も高いことから、従来より各種の発熱装置の
発熱源として広く利用されている。 As is well known, positive characteristic porcelain heating elements have a self-temperature control function that automatically controls self-heating by rapidly increasing electrical resistance when a certain temperature is reached, and unlike nichrome heating elements, there is no danger of overheating. Since it is safe and highly reliable, it has been widely used as a heat source in various heat generating devices.
正特性磁器発熱体は、一般にはペレツト状に形

いる場合には素子の使用数が多くなり、性能面、
コスト面において不利になる欠点を生じる。 Positive characteristic porcelain heating elements are generally formed in the form of pellets, but in the form of pellets, the amount of heat generated per element is small, making it suitable for use as a heat source in hair dryers, warm air machines, clothes dryers, etc. that generate over several hundred watts. In this case, the number of elements used increases, and performance issues
This results in disadvantages that are disadvantageous in terms of cost.
こうした欠点を解決するため、第１図に示すよ

して使用されるようになつてきた。 In order to solve these drawbacks, a honeycomb-shaped positive temperature characteristic porcelain heating element has been proposed in which a large number of through holes 2 are provided in the thickness direction of a porcelain body 1, as shown in FIG. This positive characteristic porcelain heating element has a very large effective surface area per unit volume, and by allowing fluid such as air to pass directly through the through holes 2, efficient heat dissipation can be obtained, which is not possible with conventional pellet-shaped heating elements. It is possible to generate more than several hundred watts of heat per element, and it can also extract hot air with excellent temperature rise characteristics, making it suitable for large-capacity products that require air blowing, such as hair dryers, hot air blowers, and clothes dryers. It has come to be used as a heat source.
上述のような各製品に正特性磁器発熱体を組込

特性磁器発熱体を支持するようにしてあつた。 When incorporating a PTC porcelain heating element into each of the above-mentioned products, conventionally, as shown in FIG. Ring-shaped holders 5 and 6 made of synthetic resin were brought into contact with each other, and the PTC porcelain heating element was supported via the holders 5 and 6.

量が得られるからである。 By the way, recently, in order to increase the calorific value, the Curie temperature of a positive characteristic heating element is, for example, 220℃.
There is a tendency to use products that fall within the above high temperature range. That is, when the amount of heat generated (power consumption) is W, the heat radiation coefficient is C, the Curie temperature is T c , and the ambient temperature is T a , the following relational expression is established, and the Curie temperature T This is because the greater the temperature difference between c and the ambient temperature T a , the greater the amount of heat generated.

れていた。 However, as mentioned above, conventionally, the holders 5 and 6 are made of synthetic resin, and even if heat-resistant synthetic resin is used, the heat resistance is limited to about 220°C, making it difficult to incorporate a high-temperature positive characteristic porcelain heating element. In regards to this,
There has been a strong desire to develop a holder with higher heat resistance.
