[Effect of device]

 The present invention is directed to a top plate portion and a first hood member integrally formed by integrally molding a back plate portion at a right angle downward from a rear edge of the top plate portion, and a front plate portion and left and right side edges of the front plate portion. A second hood member detachably attached to the first hood member and a filter detachably attached to the first hood member, which is configured by integrally molding the left and right side plate parts in a right-angled rearward direction Since it is composed of a fan unit equipped with, it becomes a range hood fan that can be assembled and completed easily at the construction site without being restricted by space.

Therefore, the construction space or the like has already been limited by kitchen equipment such as a stove or a sink, and the construction space is limited due to the presence of a hanging door or the like at the time of replacement or maintenance of the range hood fan. Even if it has been done, it can be easily and reliably installed without the troublesome work of a conventional range hood fan.

The present invention comprises a first hood member formed by integrally molding a top plate portion and a back plate portion, and a single hood member formed by integrally molding a front plate portion and left and right side plate portions. Since the range hood is composed of two members, the second hood member and the second hood member, and the number of parts is small, the work of connecting the parts (bolting work, etc.) or their positioning work can be reduced, and the structure described above can be achieved. This makes the range hood robust.

Further, in the prior art, since the fan motor was integrally incorporated in the range hood, there was a problem that the entire range hood fan had to be replaced without replacing the fan motor only. According to this, for example, the front plate part and the left and right side plate parts are integrally molded, and the fan unit can be easily formed by removing only the second hood member detachably attached to the first hood member. Since it can be removed, it is very convenient to use when replacing the fan motor or performing maintenance.

Furthermore, since the first hood member, the second hood member, and the fan unit are separately attachable / detachable, it is not necessary for a large number of people to perform the work as in the conventional case, and one person can perform the work very easily. Excellent workability.
