Here, with reference to FIG. 7 (a), (b), the effect | action and effect of this range hood 1 are demonstrated.
When cleaning the front space SP3 of the accommodation space that is a passage path for air containing smoke or the like, when the button 32 on the inner side surface 31a of the front guide plate is pressed, the front edge portion of the rear guide plate 33 at the closed position L1 33b is released from the button 32, and the rear guide plate 33 is rotated forward about the rear edge 33c. Then, as shown in FIG. 7A, the protruding portion 21 enters relative to the notch portion 36 b and the latching portion 36 is hooked on the protruding portion 21. Accordingly, the rear guide plate 33 released from the holding of the button 32 is held at the latching position L2 in the middle of opening, and the front space SP3 is slightly opened. Since the rear guide plate 33 is temporarily held at the latching position L2 in this way, the rear guide plate 33 does not suddenly rotate to the open position L3 even if the rear guide plate 33 is not supported by hand when the button 32 is pressed. .

  When the rear guide plate 33 is held at the latching position L2, the center of rotation of the rear guide plate 33 in which the rear guide plate hooking portion 48 is inserted into the insertion hole 33e is near the boundary between the base portion 48a and the intermediate portion 48b. It is said that. When the rear guide plate 33 is lifted by hand from this state, as shown in FIG. 7B, the latching portion 36 at the rear guide plate side edge is slightly moved upward, and the projecting portion relatively protrudes from the notch 36b. The latching portion 36 is detached from the protruding portion 21 so that 21 is removed. Further, the center of rotation of the rear guide plate 33 is slightly shifted upward. Therefore, the rear guide plate 33 lifted from the latching position L2 to the climbing position L21 is released from the holding, and can be rotated forward about the rear edge portion 33c. In this state, the rear guide plate 33 can be pulled out to the front while being held by hand, and the rear guide plate 33 can be lowered according to the rotation. Then, as shown in FIG. 4, the rear guide plate 33 is in an open position L <b> 3 where it is caught by the rear guide plate hooking portion 48 and hangs down. Thereby, the front space SP3 of the accommodation space is widely opened. If necessary, the rear portion of the rear guide plate 33 may be cleaned by removing the latch portion 33d from the rear guide plate hooking portion 48.

As described above, when the front side of the exhaust means 60 is opened, the rear guide plate 33 is temporarily held at the intermediate latch position L2 by the hook portion 36 on the rear guide plate side being hooked on the protruding portion 21. Accordingly, the range hood 1 can suppress the rear guide plate 33 from vigorously rotating from the closed position L1 to the open position L3 that greatly opens the front side of the exhaust means 60 with a simple configuration.
Further, when the rear guide plate 33 is rotated from the latching position L2 to the open position L3, the rear guide plate 33 is naturally lifted to the open position L3 by hand so that the rear guide plate 33 is manually lifted to the open position L3. It will be. Also from this, it can suppress that the rear part guide plate 33 rotates vigorously to the open position L3.

Further, since the range hood 1 is inclined so that the front upper side 40a1 of the partition plate is the front side, the front upper side 40a1 of the partition plate is obliquely forward compared to the case where the front side of the partition plate is provided along the vertical plane. It will be the position that advanced below. Therefore, even if the range hood 1 is provided at a high place above the cooking device as shown in FIG. 1, it is easy to reach the front upper side 40a1 of the partition plate. Therefore, this range hood 1 has improved cleaning properties.
When cleaning the fan 61, the bell mouth 50 is removed from the partition plate 40, and the fan 61 is taken out through the through hole 41 of the partition plate. After completion of cleaning, the fan 61 is returned to the original position and the bell mouth 50 may be attached to the partition plate 40.

  When attaching the rear guide plate 33 to the hood main body 10, first, the rear guide plate hooking portion 48 is inserted into the insertion hole 33 e and the rear guide plate hooking portion 33 d is hooked on the rear guide plate hooking portion 48. In this state, the rear guide plate 33 is rotated around the rear edge portion 33c to the climbing position L21 as shown in FIG. Further, when the rear guide plate 33 is pushed rearward, the center of rotation of the rear guide plate 33 is near the boundary between the base portion 48a and the intermediate portion 48b, and the rear guide plate front edge portion 33b is pressed against the button 32 biased downward. Is hooked. Thereby, the rear guide plate 33 is held at the closed position L1. Therefore, when the filter 35 is attached to the opening 34, the range hood 1 can again discharge air containing smoke or the like.

(3) Modification:
Various modifications can be considered for the present invention.
For example, the rear guide plate and the front guide plate may be divided into two or more. Further, the front guide plate may have a shape deviated from the circular arc shape of the vertical cross section, such as a shape of a part of the circumference of an ellipse whose vertical cross section is deviated from the circle. The guide unit can generate a swirling flow even if a flap is not provided.
The opening for allowing air containing smoke or the like to pass from the open space to the accommodating space may be provided in the side panel 20 although it is preferably provided in the rear guide plate. Although the said opening part is suitable if it exists in both right and left, you may be made into only one. Moreover, although it is suitable if the air containing the smoke etc. which were collected in open space is made into a swirl flow, it does not need to be made a swirl flow.
The open space connected to the accommodation space via the opening may be divided into two or more.
The suction mouth of the bell mouth and the through hole of the partition plate may be non-circular such as an ellipse or a polygon in addition to the circular shape.
