[15] 图 2是本发明第二实施例的太阳能加热器的器壁和盖体的剖视图；
[16] 图 3是本发明第三实施例的太阳能加热器的盖体的剖视图；
[17] 图 4是本发明第四实施例的太阳能加热器的剖视图。
本发明的实施方式
[18] 下面结合附图对本发明作进一步详细说明。
[19] 请参阅图 1， 显示本发明第一实施例的太阳能加热器。 该太阳能加热器 10包括 双层器壁 4和双层的盖体 1， 该双层的盖体 1盖设于器壁 4上构成受热腔 8， 该双层 器壁 4设置于一反射盘 7中， 该双层器壁 4是夹层， 双层器壁 4的内部是真空密闭 的， 双层的盖体 1也是夹层， 内部也是真空密闭的。 所述双层器壁 4和双层盖体 1 的外层为透光层， 例如釆用透明材料如玻璃或石英等制成。 器壁 4和盖体 1的双 层也可以都釆用透明材料， 在内层壁上涂有黑体材料 9。 在图示的实施例中， 太 阳能加热器为一个加热杯， 当然， 图中的结构仅用于说明本发明的原理， 并不 用于限制本发明的结构及保护范围。 本实施例中， 器壁 4即为杯体 4， 盖体 1为杯 盖 1。
[20] 该双层器壁即杯体 4和盖体即杯盖 1的内层壁上分别涂有黑体吸热材料 9， 并且 可以是涂在直接面向受热腔的杯体 4的内表面 5和杯盖 1的内表面 2上。 通过黑体 吸热材料 9增加太阳光的利用效率， 使得更多的太阳能迅速转化为热能， 以便迅 速加热受热腔 8内食物或液体等， 如咖啡或茶水等。 双层器壁 4和双层盖体 1中的 真空即能起到保温作用， 还不影响太阳光照射至黑体吸热材料 9上。
[21] 反射盘 7的内表面 6呈现抛物面结构， 杯体 4设置于反射盘 7的抛物面中心位置， 以便使太阳光线经内表面 6反射会聚照射到杯体 4上。 反射盘 7的内表面 6可以是 镀金属的镜面， 如镀铝或镀银等， 并不限于此。
[22] 杯盖 1的内层壁向受热腔 8内凸伸并低于杯体 4的敞口边沿 （即杯口边沿） 。 另 夕卜， 在杯盖 1的内层壁与杯体 4的内层壁相接处具有导气槽 3， 供受热吋排气用。 导气槽 3可以是由杯盖 1的内层壁或杯体 4的内层壁上的凹槽形成。 杯盖 1和杯体 4 外表为弧形， 用以增大受光面积。
[23] 在太阳能加热器 10使用吋， 例如煮咖啡吋， 将其置于太阳光下， 太阳光照射至 杯体 4及杯盖 1吋， 具有吸热保温的杯体 4的内表面 5立即受热使加热器内装的液 体受到加热， 同样杯盖 1的内表面 2也具备加热保温功能。 另外， 同吋通过太阳 光照射下反射盘 7的内表面 6的抛物镜面结构， 使太阳光线反射会聚再次照射到 杯体 4上， 使加热器 10受到的光强度得到叠加， 杯内装的受热液体温度升高得更 快更高， 非常适用于煮咖啡或泡茶。 而且， 只要太阳能加热器 10放在太阳光下 ， 就能受热， 因而不容易受凉。 此外， 由于釆用真空双层结构， 即使不在太阳 光照射下， 也能保温很长吋间。
[24] 请参阅图 2， 显示本发明第二实施例的太阳能加热器的器壁 4和盖体 21， 本实施 例的太阳能加热器其它部件的结构基本类似于第一实施例中的太阳能加热器 10 ， 在此不再赞述。 两者不同之处主要在于盖体结构， 如图所示， 本实施例的盖 体 21的内层壁进一步设有导热柱 22， 该导热柱 22伸入到受热腔 8的底部用于与待 加热物接触， 以便将盖体 21上的吸热快速传导至被加热的物体。 导热柱 22可以 是实心的导热柱体或空心的导热筒， 并釆种导热性良好的材料如铜、 铝等。 通 常， 在加热器盛满食物或液体吋， 盖体 21的内层壁可以与食物或液体直接接触 ， 利用第一实施例结构的盖体 21即可将热量充分传导到受热物体， 然而， 当加 热器盛满处于未盛满状态吋， 此吋需要导热柱 22将盖体 21上的热量快速传导至 被加热的物体， 以提高加热效率。
[25] 请参阅图 3， 显示本发明第三实施例的太阳能加热器的盖体 25， 本实施例的太 阳能加热器其它部件的结构基本类似于第一实施例中的太阳能加热器 10， 在此 不再赞述。 两者不同之处主要在于盖体结构， 如图所示， 本实施例的盖体 25的 内层壁不仅向受热腔 8内凸伸， 且盖体 25的内层壁中部为进一步向受热腔底部凸 伸的导热部 26， 用于与待加热物接触。 该导热部 26的内表面也涂有黑体吸热材 料 9。 该导热部 26—方面能够增大吸热面积， 另一方面将盖体 25内层壁上部吸收 的热量充分传导到受热物体， 从而提高加热效率， 进一步增加太阳光的利用率
[26] 请参阅图 4， 显示本发明第四实施例的太阳能加热器 40， 本实施例的太阳能加 热器结构基本类似于第一实施例中的太阳能加热器 10， 相同的元件釆用相同的 标号， 在此不再赞述。 两者不同之处主要在于太阳能加热器 40还具有一电加热 系统， 优选为电磁加热装置。 本实施例中的电磁加热装置是利用电磁感应原理 加热的电磁感应加热盘 41， 其设置于反射盘 7和器壁 4之间， 双层的器壁 4的底部 支撑在该电磁感应加热盘 41上， 电磁感应加热盘 41的盘面形状与器壁 4的底部轮 廓紧密配合。 电磁感应加热盘 41内设有线圏， 在没有太阳光或光线较弱吋， 可 釆用电辅助加热方式， 电流通过电磁感应加热盘 41的线圏吋产生磁场， 磁场内 的磁力线通过位于磁场内的导磁金属体吋， 即会在导磁金属体内产生无数小涡 流， 使导磁金属体自行高速发热， 热量传递到器壁 4上， 从而对受热腔 8内的物 体进行加热。 导磁金属体可以是设置在电磁感应加热盘 41自身， 也可以是器壁 4 的内层壁具有导磁金属材料或者内层壁由导磁金属制成， 如铁、 钴、 镍等， 成 为导磁壁， 黑体吸热材料即涂于导磁壁的内表面， 这样， 当开启电磁感应加热 盘 41吋， 器壁 4的内层壁直接发热， 以对受热腔 8内的物体进行加热。 由于电磁 感应加热盘 41是利用电磁感应原理加热， 使得加热盘 41可以与器壁 4间隔一定距 离， 可方便在加热盘 41与器壁 4之间设置支架等辅助结构， 给加热器 40留有更灵 活的结构调整空间。 [27] 在上述各实施例中， 通过双层的器壁 4及盖体 1， 可充分利用太阳能来加热受热 腔 8中的物体， 进一步， 反射盘 7使太阳光线反射会聚到透明的器壁 4， 可再次利 用太阳能来加热受热腔 8中的物体， 使加热器受到的光强度得到叠加， 加热器内 装的受热物体温度升高得更快更高。 因此， 太阳能加热器能够用太阳能来加热 ， 具有环保节能、 安全方便， 能够吋刻加热保温等特点， 适合野外旅游和自家 花园室外使用。
[28] 以上所述仅为本发明的较佳实施例而已， 并不用以限制本发明， 凡在本发明的 精神和原则之内所作的任何修改、 等同替换和改进等， 均应包含在本发明的保 护范围之内。
