DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
The present embodiment shown in FIGS. 1 to 6 relates to a kitchen ventilator that discharges oily smoke, steam, odor, and the like associated with cooking. This ventilator has a flat bottom (about four times the horizontal dimension with respect to the vertical dimension) and a horizontally long hollow box 3 that has an exhaust port 2 that opens to the outside and can communicate with the outside as a suction port 1. The blower 4 is incorporated so that its blade rotation surface is substantially horizontal (see FIG. 2). A grease filter 5 is detachably attached to the suction port 1 of the box 3, and the blower 4 forms an air flow from the suction port 1 to the exhaust port 2 opened on the back surface or the side surface through the grease filter 5. The processing air volume of the blower 4 is set to about 100 m ³ / h to 290 m ³ / h.
[0017]
Both sides and the rear surface of the box 3 are extended downward, and as shown in FIG. 3, a hood portion 6 having a substantially right-angled isosceles triangle shape is formed. An inward channel-shaped oil receiver 7 is formed at the lower end of the back surface of the hood portion 6. A front cover 8 is attached to the front surface of the box 3, a lamp 9 is incorporated in the front cover 8, and an operation panel 10 is attached to the front surface. On both sides of the hood portion 6, there are provided inclined plates 12 that obliquely enter inward from the inclined edges 11, and an isosceles trapezoidal guide plate 13 is obliquely mounted between the upper end of the inclined plate 12 and the oil receiver 7. (See FIG. 1). The inclined plate 12 is provided with an inverted triangular opening 14 having a wide upper side. The lower edge of the guide plate 13 is received by a support portion 15 in the oil receiver 7 with a dimension between the side surfaces, and the upper edge is shorter than the lower edge and is screwed to the inclined plate 12. Since the rotation axis of the motor 16 of the blower 4 is in a substantially vertical direction, the oil receiver 7 is less projected forward, and the structure is simplified and the design is simplified by holding the guide plate 13 in the oil receiver 7 portion. Will also increase.
[0018]
The guide plate 13 is in the hood portion 6, and has an inclination angle θ that has a larger angle with respect to the horizontal plane than the inclined edge 11 on the side surface of the hood portion 6. For example, when the angle of the inclined edge 11 on the side surface of the hood 6 is 45 degrees with respect to the horizontal plane, the inclination angle θ is set to around 50 degrees. As a result, both sides of the guide plate 13 can be surrounded by side surfaces that protrude downward downward as it goes upward. The upper edge of the guide plate 13 is at a position about 430 mm from the back surface substantially corresponding to the lower part of the front edge of the box 3, and a gap 17 is formed between the front edge of the box 3. The width of the gap 17 is set to around 40 mm. This gap and the gap 18 on both sides of the inverted triangular hood 6 serve as a substantial suction port.
[0019]
As shown in FIG. 3, the ventilator is attached in a state where the back surface is in contact with the wall surface 19 of the kitchen. At the time of construction, the height from the heating work surface of the gas table or the electromagnetic cooking device 20 to the grease filter 5 is secured at least 800 mm. Since the clearance 17 at the upper edge of the guide plate 13 is at a front side position of about 430 mm from the back surface, the gap 17 is located immediately above the pan or frying pan placed on the heating work surface of the gas table or electromagnetic cooker 20.
[0020]
In the cooking with the electromagnetic cooker 20, no flame is used, so steam, odor, oil droplets, etc. generated from a pan or the like during cooking rise with a weak draft due to temperature difference. The rising vapor, odor, oil droplets, etc. hit the induction plate 13 directly above and spread with an ascending component so as to approach the surface of the induction plate 13 by the Counder effect. Water droplets or oil droplets generated when steam or the like collides with the guide plate 13 flows down along the slope of the guide plate 13 and is received by the oil receiver 7 at the lower end.
[0021]
On the other hand, the air sucked into the suction port 1 through the grease filter 5 by the rotation of the impeller of the blower 4 is pressurized and exhausted from the exhaust port 2 to the outside of the room. The air flow due to the operation of the blower 4 is sucked at a flow rate of about 2 m per second from the inverted triangular opening 14 of the inclined plate 12 and the gap 17 at the upper edge of the guide plate 13. This suction speed is faster than the speed of the airflow containing steam, odor, oil droplets, etc. that spreads along the guide plate 13 by the draft, and is effectively sucked without diffusing steam, odor, oil droplets, etc. Can be discharged.
[0022]
There is nothing to be heated under the induction plate 13 (near the wall), there is almost no rising steam or odor, and rising steam or odor is directly above the pan or frying pan placed on the heating work surface. In many cases, steam and odor hitting the guide plate 13 also have components in the upward direction. Accordingly, a large amount of steam, odor, etc. is generated, and a gap 17 of about 40 mm is set at a place where the steam and odor are gathered, and the openings 14 with the opening area wider on the upper side are provided on the left and right, so that steam and odor are efficiently produced with a small air volume. Can be inhaled and discharged. The inclined plate 12 smoothly guides the airflow to the opening 14 and increases the collection performance. Further, since the inclination angle θ of the guide plate 13 is larger than the angle of the inclined edge 11 on the side surface of the hood portion 6 and the enclosure on both sides of the hood portion 6 becomes larger toward the upper side, rising steam and odor Or the spreading | diffusion to the side of an oil droplet etc. can be prevented effectively. Since this ventilator has a right-angled triangle on the side surface, there is little feeling of blockage and the user's head is less likely to hit, so that it can be installed in a low place and has a feature of less draft in cooking. It is suitable for local ventilation of the kitchen equipped with.
[0023]
If it is a ventilator for the electromagnetic cooker 20, the processing air volume of the exhaust fan 4 is about 100 m ³ / h to 290 m ³ / h, and it can sufficiently collect and discharge steam and odors accompanying cooking, and is low. It becomes a ventilator with a good feeling of use that does not have a cold wind feeling at the feet due to noise. The guide plate 13 may have a curved surface structure 22 or a curved surface structure 22 in the suction direction as shown in FIGS. By adopting such a configuration, the rigidity of the guide plate 13 can be increased and a texture can be imparted.
[0024]
FIG. 6 is an explanatory diagram showing a comparison of the relationship between the air volume and the collection rate of the conventional ventilation device (B) shown in FIG. 8 and the ventilation device (A) of the present embodiment.
