本发明实施例具有一柜式壳体， 其它组成部件均安装在该柜式 壳体内或安装在该柜式壳体上， 该柜式壳体包括四根用于支撑的支杆 15， 在该支杆 15 顶部安装有顶盖 1 1， 在该支杆 15 的底部安装有用 于支撑 '整个装置的底座 17， 这样通过顶盖 1 1、 支杆 15 以及底座 17 组成了一支撑该装置的基体。 需要说明的是， 组成该基体的支杆 15 的数量是可以变化的 而不限定在四根支杆 1 5 的数量上。 同时在该 支杆 1 5的中点处也即整个柜式壳体的中部安装有一固定板 1 3， 其将 该柜式壳体分隔为上、 下两部分空间， 下部分空间四周由设置在上述 支杆 1 5之间的围板 14围成， 其围板 14下部设置有空气进孔 1 6， 用 于空气在上述下部空间以及壳体外部的流动， 并且在围板 14上部设 置有散热孔， 该散热孔也起到部分空气流动的作用， 同时至少一个围 板 14可旋转的设置在上述的支杆 15上， 这样可以以该围板 14为开 门结构以便于査看和修理设置在该柜式壳体内部的各部件。
固定板 1 3是一中心设置有通孔的分隔板， 其下面附着安装着燃 烧装置， 该燃烧装置包括阀体 5 1、 喷嘴 52、 燃烧器 53、 防倾倒装置 54、 减压阀 55。 阀体 5 1共有三路进出气通路， 其中两路为进气通路， 其中一通路为燃气通路， 另一路为空气通路， 燃气通路与家居的燃气 供给设备相连接， 在该燃气通路上还安装一防倾倒装置 54， 该防倾 倒装置 54 是在该暖风装置倾斜一定程度的情况下即切断燃气供给通 路， 以防止由于该暖风机倾倒之后仍继续工作而造成的危险； 而另一 路空气通路的通路进口一直延伸到该暖风机下部空间的空气进孔 16 的附近， 其上安装有减压阀 55 ; 阀体 51最后一路出气通路连接燃烧 器 53， 燃烧器 53上设置有喷嘴 52， 喷嘴 52釆用的是电点火方式， 这样，通过控制喷嘴 52点火燃烧阀体 5 1中的燃气与空气的混合气体， 阀体 5 1 内气压减小， 空气通路上的减压阀 55打开， 空气进入空气通 路中与燃气在阀体 5 1 内持续混合以保持喷嘴 52上火焰的持续延烧， 而当关闭燃气通路， 而相应的阀体 51 内燃气与空气混合气体燃烧殆 尽之后，阀体 5 1 内充满空气与外部的空气气压相等，减压阀 55关闭， 该暖风机停止工作。 .
燃烧器 53的作用为将喷嘴 51的火焰扩大后通过辐射筒 22将火 焰辐射出来的能量不断的进行反射以将辐射筒 22 中的空气温度提 髙，该辐射筒 22为以附着安装在上述固定板 1 3上的圆柱形管状零件， 其纵向通孔与上述固定板 13上设置的通孔对应， 同时上述的喷嘴 5 1 与燃烧器 53 同样与固定板 13 上的孔径相对应。 另外在该辐射筒 22 的下部表面上设置有至少两排用以通气的圆孔，该圆孔可以增加空气 的流动速率。 在该辐射筒 22的正上方， 在上述顶盖 1 1 的下表面上设 置有反射板 21与送风装置， 该送风装置为一离心风机 31， 该离心风 机 31 叶轮的轴线与上述辐射筒的纵向轴线基本保持在同一垂直线 上， 这样当离心风机 31 工作时， 其通过轴向的进风， 也即将辐射筒 22中的加温之后的空气吸出， 再向四周送出， 而离心风机 3 1上设置 的反射板 2 1 为反向安装在上述离心风机 3 1 以及顶盖 1 1之间的圆台 形零件， 其同时加强了对空气的反射以及由喷嘴 51 产生的热量的反 射， 增强了暖气机的暖气加温效果。 另外在上述由固定板 13 分隔的 上部空间是由安装在支杆 15之间的围网 12所围成的， 该围网 12可 以是一般的金属网， 根据支杆 1 5 的数量以及它们之间的间距设置该 围网， 在这里不作进一步说明。 通过釆用上述的技术方案， 该暖风机 能够快速的提高空气温度， 并将暖风向四周空间送出。 为了方便使用者的使用以及对该暖风机的控制， 如图 1 在本实 施例的暖风机的正前方围板 14 的方便操作的位置上设置有控制显示 装置， 其包括阀体旋钮 61、 电源开关 62、 调速旋钮 63、 工作指示灯 64、 欠压指示灯 65、 充电指示灯 66。 其中阀体旋钮 61与上述燃烧装 置中的阀体 5 1连接在一起， 通过调节阀体旋钮 61来调节阔体 51 的 开关大小来控制燃烧器 53火焰的大小； 电源开关 62与本暖风机的电 源装置 41 相连接， 该电源装置 41设置在底座 17上， 如图 2所示， 其为交直流两用电源， 交流电源为 1 10V , 50 - β ΟΗζ , 直流电源为储 能电池， 同时电源装置 41还为离心风机 31与控制装置提供电源， 具 体连接将在下述说明书中说明， 电源开.关 62即控制电源装置 41 的开 关； 调速旋钮 63与离心风机 3 1连接用与控制离心风机 3 1 的转速； 工作指示灯 64表示电源开启之后电路与气路的工作正常， 给该工作 指示灯 64连接在上述电路中；欠压指示灯 65与储能电池连接用以提 示用户储能电池的电压已经下降到一定程度， 提醒用户需要充电； 充 电指示灯 66 表示当前暖风机正工作在使用交流电源的状态下， 同时 也表示储能电池正在充电。
如图 3 所示为电源装置与暖风机其它各部分连接关系的电路框 图，输入为交流电源时，通过 AC/DC转换将交流电源转化为直流电源， 而直流电源通过充电控制为当使用交流电源时通过 AC/DC变换，经电 源开关直接给离心风机 3 1 供电同时向储能电池充电， 充电指示绿灯 亮， 当储能电池接近充满时， 绿灯会慢慢变暗保持在某一状态， 维持 小电流充电， 一般充电时间为 4- 6 小时 （视电池容量而定）。 在无交 流电的情况下使用时， 用储能电池供电， 储能电池供电可用 6- 8小时 (视电池容量而定）， 当电池电压下降到一定时， 警告灯黄灯亮， 提 醒用户及时充电，以免电池过量放电而缩短使用寿命，如果继续使用， 欠压检测电路会自动关闭离心风机 31和阀体 51 , 并发出报警声， 必 须关闭电源充满电后， 重新开启才能使用， 充电时最好将电源开关关 闭， 以缩短充电时间。 通过釆用上述的控制显示装置以及电源装置可 以很方便的使用以及控制该暖风机的工作。 因此采用上述的技术方案， 本发明提供了一种结构相对简单、 对空气加温的温度上升快、 安装容易、 操作控制方便并且结构上安全 可靠的柜式暖风机。
