Abstract

本发明提供了一种双聚焦太阳灶，属太阳能灶具领域。传统太阳灶虽用途广泛，当人们用传统太阳灶炒菜、烙饼时，无法控制热量，热效率利用不高，还存在反光面大，占用面积大的缺点，本发明解决了上述问题。其特征是：在传统太阳灶的聚光点处即一次聚焦处是一个多凸透镜，多凸透镜下面是挡光板，多凸镜内的各个凸透镜的焦点处即二次聚焦处是受热体架，当炒菜、烙饼、做饭时，被加热体放在受热体架上，当温度过高时调节挡光板面积，来控制被加热体温度，达到本发明目的。

Description

双聚焦太阳灶
所属领域  本发明提供了一种双聚焦太阳灶，属太阳能灶具领域。
背景技术  传统太阳灶虽用途广泛，当人们用传统太阳灶炒菜、烙饼时，无法控制热量，热效率利用不高，还存在反光面大，占用面积大的缺点，本发明解决了上述问题。
发明内容  本发明的目的是针对上述太阳灶中存在的问题，提供了一种双聚焦太阳灶。本发明由可调节底座，底座与太阳灶反光板相连，反光板上方安装一个竖支架，反光板的聚光点处即一次聚焦处是一个多凸透镜与竖支架相连，凸透镜下面是可调节扇形挡光板与竖支架相连，凸透镜上面各个凸透镜的焦点处即二次聚焦处是受热体架与竖支架相连，挡光板下是两根可调节斜架与竖支架相连，上面与凸透镜架和受热体架相连。调节斜支架调节钮可调节凸透镜至反光板聚光点处，并调节凸透镜使多凸透镜焦点至受热体架，起到加热效果。由于双聚焦热效率利用比日常太阳灶高，反光板比日常太阳灶反光板面积小，即可达到发明目的。
附图说明  附图是双聚焦太阳灶的主视图：图中(1)是多凸透镜，(2)是斜支架，(3)是竖支架，(4)是可调节底座，(5)是反光板，(6)斜支架调节钮，(7)是可调节档光板，(8)是受热体架。结合附图对双聚焦太阳灶做进一步说明：多凸透镜(1)在反光板聚焦处，多凸透镜片大小能使各个凸透镜的焦点分布在被加热体底部既可，多凸透镜片均匀分布，大小一致，耐聚光高温，用优质玻璃制作。挡光板(7)扇形结构金属片，可打开扇形部分挡住部分反射光来调节被加热体温度。
具体实施方式  当人们用双聚焦太阳灶加热时，同日常用太阳灶一样，调节底座(4)，在反光板(5)的聚焦处是多凸透镜(1)，再调节受热体架(8)至多凸透镜(1)的多个焦点处，把被加热体放在受热体架(8)上，当温度过高时，调节挡光板(7)遮住部分反射光达到调节热量目的，即可炒菜、烙饼、烧水、做饭。

Claims (1)

1.一种双聚焦太阳灶，其特征在于日常太阳灶的聚光点处是一个多凸透镜，这个多凸透镜下面是挡光板，凸透镜内各个凸透镜的焦点处是受热体架。
