Abstract

本实用新型属于一种家庭用品。具体地说是一 种用于保温并加热食品的盒子。
该保温盒由盒体及盖构成,盒体包括外壳与内 壳,在外壳与内壳之间有保温层,在内壳底部与保温 层之间设置发热元件,发热元件中的两块绝缘片分别 与内壳及保温层接触,在绝缘片之间放置电热元件, 电热元件上引出的导线与位于外壳底部的电源插座 联接,在内壳内部有隔板。

Description

本实用新型属于一种家庭用品。
对职工而言,带着午饭去上班是比较普遍的,目前常用的带饭用具大多为搪瓷杯或铝壳饭盒,或者玻璃保温瓶等,其中前两种用具在用饭时需通过其它加热器重新加热,比较麻烦,后一种用具内的饭菜因长时间处在高温下,使食用者的口味受到影响。
本实用新型的目的是设计一种既能方便携带,又能自动加热的保温盒。
其特点是该保温盒由盒体及盖8构成,盒体由内壳5与外壳1构成,在外壳1与内壳5之间有1层保温层2,在内壳5的底部与保温层2之间设置发热元件,发热元件由电热元件4,绝缘片3构成,电热元件4放置在两块绝缘片3之间,其中1块绝缘片3与内壳5的底部接触,另1块与保温层2接触,在电热元件4的正、负极引出的导线与安装在外壳1底部的电源插座7联接,在外壳1的上面有盖8,在内壳5内有隔板6,将保温盒隔为两个部分,以便分别盛放饭与菜,用饭前,接通电源,便可对盒内饭菜进行加热。
其中的电热元件可以是PTC陶瓷发热材料,也可以是DZR电热膜或电热丝或电热片等。
本实用新型的优点是携带方便,操作简单,盒内食品的口味不会发生变化。
图1为本实用新型的结构图,即摘要附图。
图2为图1的俯视图。
