PURPOSE: To enable a cooking table to be irradiated at a proper degree of lighting without being influenced by a mounting pattern against a building wall by a method wherein a lighting lamp is arranged at a lower end of a main body of a ventilation fan having a propeller fan and a fan motor in such a way that its upward or downward rotating angle can be freely adjusted. CONSTITUTION: A main body 3 of a ventilation fan is engaged with a resilient engaging spring 53 arranged at a lower end of a main body frame 13 having a propeller fan and a fan motor or the like installed therein and can be pulled out or inserted into it. A lighting lamp 4 is hung at a lower position of the main body 3 of the ventilation fan and supported there. This lighting lamp 4 is comprised of a lamp case 24 having a lamp 14 stored therein and it is supported by a bracket 34 fixed to the lower end of the main body 3 of the ventilation fan in such a way that its upward or downward rotating angle can be freely adjusted. With such an arrangement as above, even if a fixing space shows a certain difference between a cooking table edge and the main body of the ventilation fan in response to a mounting situation of the range hood fan, the lighting lamp is directed toward the most-suitable direction to enable the cooking table to be uniformly irradiated. |
