Thus, in some embodiments, the second nozzle 84 is mounted within and adjacent to the body 10. The impeller 12 is arranged (as shown in Figure 12). The third output pipe 90 and the reversing valve 83 are also mounted in the body 10. The heating device 70 and the reversing valve 83 are connected by a water pipe. The first inlet end 61 of the first output pipe 60 is connected to the reversing valve 83, and the first outlet end 62 of the first output pipe 60 is mounted on the guide of the body 10. On the flow plate 11, that is, the reversing valve 83 is installed between the heating device 70 and the first inlet end 61 of the first output pipe 60, and does not affect the first output pipe 60 and the body 10 and the second output pipe 40. assembly. Therefore, by providing a fixed cleaning pipe inside the body 10 of the range hood, it is possible to avoid assembly and disassembly of the pipe for each cleaning, and the cleaning inside the range hood is simpler and more convenient, and the cleaning efficiency is improved.

如图 10所示，第二喷嘴 84可以为喷管的形式，喷管上设有多个喷孔 840，有利地，喷管可以为第三输出管 90的一部分。喷管包括环形段 841和直线段 842，环形段 841可以邻近吸油烟机的叶轮 12的外端面设置，直线段 842伸入到叶轮 12内，从而提高对叶轮 12的清洗效果。更有利地，直线段 842邻近叶轮 12的下部，以提高对叶轮 12停止转动时位于下部且容易聚集油污的叶轮 12的叶片的清洗效果。当然，第二喷嘴 84也可以为其他形式，并且可以单独制成与第三输出管 90相连，有利地，与第三输出管 90可拆卸地相连。 As shown in FIG. 10, the second nozzle 84 may be in the form of a nozzle, and the nozzle is provided with a plurality of injection holes 840, advantageously, sprayed The tube can be part of the third output tube 90. The nozzle includes an annular section 841 and a straight section 842. The annular section 841 can be disposed adjacent the outer end surface of the impeller 12 of the range hood, and the straight section 842 extends into the impeller 12 to improve the cleaning effect on the impeller 12. More advantageously, the straight section 842 is adjacent to the lower portion of the impeller 12 to enhance the cleaning effect of the blades of the impeller 12 located at the lower portion and tending to collect oil when the impeller 12 stops rotating. Of course, the second nozzle 84 can be of other forms and can be separately formed to be coupled to the third output tube 90, advantageously detachably coupled to the third output tube 90.
