Abstract

本实用新型涉及一种用正电阻系数陶瓷片作为 发热元件的电热台板，包括底板、电热层、被覆层，其 特征是：电热层中的电热元件为正电阻系数陶瓷片， 电热层包括正电阻系数陶瓷片、云母片、导电铜片、弹 簧片、匀热铝板、绝热隔层。本产品使用安全，耗电 省、且使用寿命长。

Description

本实用新型涉及一种作为办公室用品的台板，特别是电热台板。
现有的电热台板多用电热丝作为发热元件，电热转换效率低，且使用安全性较差，一旦电热丝短路，易引起火灾。正电阻系数陶瓷片作为电热元件有其优点，不仅热效率高，而且使用安全，随着温度升高，电阻增加，有自然恒温的作用，因而广泛用于生活用品。
本实用新型的目的是提供一种以正电阻系数陶瓷片为电热元件的电热台板。
本实用新型的任务是这样实现的。本实用新型包括底板、电热层、被覆层，其特征是：电热层中的电热元件为正电阻系数陶瓷片。
图1为本实用新型的剖视图。
现结合附图对本实用新型作进一步的说明。本实用新型包括底板（1）、电热层（2）、被覆层（3），其特征是：电热层（2）中的电热元件（4）为正电阻系数陶瓷片。底板（1）为木板或胶木板。被覆层（3）为天然纤维织物或化纤织物。电热层（2）包括正电阻系数陶瓷片（4）、云母片（5）、导电铜片（6）、弹簧片（7）、匀热铝板（8）、绝热隔层（9），绝热隔层（9）可以是石棉或矿棉。被覆层（3）将电热层（2）、底板（1）包成一体。可以在此电热台板上盖以玻璃台面（10），然后用周边包角（11）将两者卡紧成为一带有玻璃台面的电热台板。
本实用新型耗电省，使用安全，且使用寿命长。

Claims (2)

1、一种电热台板，包括底板(1)、电热层(2)、被覆层(3)，其特征是：电热层(2)中的电热元件(4)为正电阻系数陶瓷片。
2、按权利要求1所述的电热台板，其特征是：电热层（2）包括正电阻系数陶瓷片（4）、云母片（5）、导电铜片（6）、弹簧片（7）、匀热铝板（8）、绝热隔层（9）。
