2. Description of the Related Art In recent years, with changes in eating habits and kitchens, various dishes can be enjoyed even at home, the use of cookers is high, and exhaust gas, oil smoke, odor, etc. generated from cookers can be efficiently removed. There is a growing demand for range hoods that emit.

Conventionally, various types of range hoods of this type have been known. For example, a range hood disclosed in Japanese Utility Model Laid-Open No. 60-146243 has been provided. Hereinafter, the configuration will be described with reference to FIGS.

[0004] As shown in the figure, a box-shaped hood body 10 is provided on a wall surface 101 of a house so as to cover the upper part of a cooker (not shown), and has a suction opening 102 with an open lower surface.
3 has a left intake hole 104 and a right intake hole 104A on the left and right sides at the center in the left-right direction.
Fan 108 including a fan casing 106 having a built-in fan and an electric motor 107 for driving both suction fans 105
Is provided.

The suction port 102 in the hood body 103
Above the filter body 109, a filter 109 is disposed so as to incline upward from near the lower end of the inner wall surface at the rear of the hood body 103 toward the front. A space 110 for collecting oily smoke is formed therebetween.

A discharge port of the fan casing 106 is connected to a duct 112 communicating with the outside 111.

In the above configuration, when the electric motor 107 is driven, the two suction fans 105 rotate, and the oil smoke generated from the cooker is sucked into the hood main body 103 from the suction port 102 and collides with the filter 109. The oil smoke stays in the space 110 below the filter 109 in the hood body 103, and then the filter 10
Go through 9. At that time, the fat and oil components
09 is removed. The oil smoke is sucked into the inside of the fan casing 106 from the left intake hole 104 and the right intake hole 104A provided on both sides of the fan casing 106, and is discharged to the outside 111 through the duct 112.
