Abstract

一种蓄热式真空保温桶,技术方案要点是:在桶体外壳内设置真空保温层和加热层,加热层内装有加热体,加热体电连接控制器。本实用新型的优点是:能进行蓄热,并和真空保温结合起来,有效地延长了保温时间,特别适宜野外作业、长途旅行和中小学生午间就餐等需要。

Description

蓄热式真空保温桶
本实用新型属于一种保温器具,特别适用子野外工作者、长途旅行者、中小学生中午吃饭等问题。
现有市场上所售的保温桶是六十年代产品,它存在如下缺点:(1)、由于保温性能差,所以保温时间短;(2)、由于它是采用玻璃镀银后做内桶,故极易损坏;(3)、它没有蓄热功能,是将待保温的物体直接放入保温桶内,故保温桶表身将吸入一定热量,导致需保温的物体温度下降。
本实用新型的目的是提供一种新型的蓄热式真空保温桶,它将蓄热与保温有机的结合起来,可有效地提高保温时间,结构精巧,结实耐用。
本实用新型的目的是这样实现的:它包括桶体外壳、桶盖、菜盒和提手,其特征是:在桶体外壳内设置真空保温层和加热层,加热层内装有加热体,加热体电连接控制器。
使用时,先通电蓄热,然后将待保温的食物等放入保温桶中,盖上桶盖,待控制器指示灯亮,则可切断电源,即可以带着外出或放置一旁,进行长时间保温。它的保温原理是:由于它在保温前,先蓄积了一定的热量,桶内已经有了一定的温度,因此食物不会因为桶内是凉的而降低温度,又因为加热层外是真空保温层,而待保温的食物在最内层,热量散失首先由蓄热层开始进行,由于真空保温层的作用,蓄积的热量散失的非常慢,故而可以延长保温时间。
本实用新型的优点是:能进行蓄热,并和真空保温结合起来,有效地延长了保温时间,特别适宜野外作业、长途旅行和中小学生午间就餐的需要;如整体结构采用不锈钢材料,不但结构精巧,结实耐用,而且外形美观光亮。
下面结合附图给出实施例。
图1是本实用新型结构示意图。
见图1,实施例具体结构如下:整体结构全部采用不锈钢材料制作,桶体的上口盖有带真空隔热层的桶盖2,上口内放置扣有菜盒盖3的菜盒4。桶体上有提手1,桶体外壳9内有真空保温层8,真空保温层的内侧设有加热层7,加热层7内装有电热丝6和充填电熔镁砂、陶瓷纤维等保温材料5。电热丝6通过导线连接桶底的控制器10(已有产品),控制器可采用时间控制器或温度控制器。在桶体外壳9上有电源插座11。
