Japanese Patent Application Publication No. 2010-127549

According to the range hood described in Patent Document 1, smoke and the like can be efficiently sucked in a horizontal spiral shape in each region before and after the smoke collecting section, and can be exhausted to the outside through the opening.
However, in this range hood, since the opening is provided in the side part, smoke, etc. flows through the side part as a flue, so the inner surface of the side part becomes the cleaning area, and the inside of the side part becomes the cleaning area. There is an inconvenience that cleaning becomes very troublesome. Moreover, since the cleaning area is spread over two areas on the left and right sides of the hood body, four filters are required to cover the opening, which increases the cleaning area of the inside of the flue and the filters, making cleaning time-consuming. There is also.
In addition, although the range hood described in Patent Document 1 is designed to make the hood body vertically thin, the height of the opening that serves as the inlet for smoke, etc. Since the minimum amount of space must be ensured, there are naturally restrictions on making the device thinner.
There are also range hoods that are made thinner by installing a rectifying plate inside the hood body and using the four sides between the inner periphery of the hood body and the outer periphery of the rectifying plate as suction ports. In the case of a hood, a current plate with a large flat area is used, which has the disadvantage of increasing the burden of cleaning.

[Purpose of invention]
The present invention was devised in view of these inconveniences, and its purpose is to enable a range hood design that eliminates the rectifying plate and reduces the size of the flue, thereby reducing the burden of cleaning. Our goal is to provide a range hood that can be made smaller.
A further object of the present invention is to provide a range hood that can be made thinner without being affected by the size of the opening that forms the suction port.

In order to achieve the above object, the present invention employs the configuration described in the claims. Specifically, the hood includes a hood body that is placed above the cooking utensil, is opened downward, and has a smoke collecting section on the inside, and an exhaust means that is equipped on the hood body.
The hood main body includes left and right side parts, a front face part curved downwardly at the front, a rear face part curved downwardly at the rear, and an intermediate face part located between the front face part and the rear face part,
A range in which a pair of left and right openings are provided between the intermediate face part and the side face part for sucking the flow of smoke, etc. that has risen to the smoke collection part into the exhaust means as a swirling flow inside each of the front part and the rear part. In the hood,
The opening includes a front opening and a rear opening connected to the front opening,
The opening is provided in an asymmetric opening shape in the left-right direction and the front-back direction,
The width of the front opening is larger than the width of the rear opening, and the length of the rear opening is longer than the length of the front opening.

Further, a flue is formed above the intermediate surface portion and is connected to the left and right openings, and the width of the flue becomes narrower toward the rear in the plane. .

According to the present invention, it is possible to form a swirling flow, which is a horizontal spiral, in each of the front and rear inner regions of the hood body and to suck the swirling flow, so that smoke, etc. can be efficiently exhausted by the exhaust means without leaking to the outside of the hood body. can do.
In addition, since the opening is provided between the intermediate surface part and the side part to suck in smoke, etc., there is no need to provide an opening in the side part, so the vertical width of the side part can be reduced and the hood body can be made thinner. Furthermore, since the size of the opening does not have any effect on the vertical width of the side surface, it is possible to provide a degree of freedom in design.
Furthermore, by making the left-right width of the front opening larger than the left-right width of the rear opening, it is possible to generate a strong swirling flow on the front side within the hood body, which allows smoke to flow outside the front of the hood body. etc. can be avoided or reduced. Furthermore, since the rear opening is longer than the front-to-back length of the front opening, it is possible to prevent smoke and the like from leaking outward from the side surfaces.
Furthermore, since the number of filters covering the pair of left and right openings can be reduced to two, cleaning performance can be improved and cost reduction can be expected.
Further, by having the flue provided above the intermediate surface portion narrower toward the rear, the planar area of the flue can be reduced, and the burden of cleaning the intermediate surface portion can be reduced. Furthermore, by arranging the exhaust means directly above the flue, the length of the flue through which smoke and the like pass can be shortened, making cleaning even easier.

The side parts 15 and 16 extend in the front-rear direction, and the front part is provided in a shape where the vertical width is gradually smaller than the rear part, and the range hood 10 is illustrated so that the upper edges of the side parts 15 and 16 are located in a substantially horizontal plane. It is designed to be installed under the ceiling or on a wall, etc.

The front part 17 is provided in a shape curved forward and downward, so that smoke, etc. rising from the lower cooking utensil side (not shown) toward the smoke collection part 20 can be formed into a horizontal spiral flow in its inner region. It has become. On the other hand, the rear surface portion 18 is provided in a shape curved rearward and downward, so that a swirling flow can be similarly formed. Note that, for the curvature of the curve, for example, the configuration described in the above-mentioned prior art document can be adopted.
On the rear side of the front part 17, an upper plane 22 to which the lower end of the curtain plate 12 is fixed extends rearward, while on the front side of the rear part 18, a lower plane 23 extends forward. It extends in one piece. As shown in FIG. 2, the upper plane 22 has a depth whose rear end is located at a position slightly forward of the rear surface portion 18 (upper position in FIG. 2), and the rear end has a width that increases from side to side toward the rear. It is provided in a shape that decreases. On the other hand, the lower plane 23 is provided in a shape whose left and right width increases toward the front. At this time, the front end of the lower plane 23 is located lower than the rear end of the upper plane 22 and has a different level (see FIG. 6), and the rear end of the upper plane 22 and the front end of the lower plane 23 are connected to the connecting wall. They are interconnected by 25. The connecting wall 25 includes a pair of left and right horizontal connecting walls 25A that are in contact with the left and right side surfaces 15 and 16, and a pair of left and right inclined connecting walls 25B that extend in the rearward inclined direction and are connected to the inner ends of these horizontal connecting walls 25A. , and a rear end central connecting wall 25C that connects these inclined connecting walls 25B.

The intermediate surface portion 19 is disposed below the upper plane 22 and within an inclined plane that rises forward so as to be continuous with the front of the lower plane 23. This intermediate surface portion 19 is provided in a shape in which the left and right widths become narrower toward the rear in plan view. The front end of the intermediate surface portion 19 is fixed to the lower surface of the upper flat surface 22. A hinge portion 19A extending in the left-right direction is provided slightly behind this fixed position, and a portion rearward of the hinge portion 19A is rotatable about the hinge portion 19A as a fulcrum.
Note that a tray 24 capable of receiving oil adhering to the upper surface of the intermediate surface portion 19 is detachably provided at the rear end portion of the intermediate surface portion 19 .
Between the intermediate surface portion 19 and the upper plane 22 is a flue 26 which is a space whose left and right width becomes narrower toward the rear within the plane. A pair of left and right openings 30 communicating with the flue 26 are provided between the intermediate surface portion 19 and the left and right side portions 15 and 16. Further, a circular hole 33 is formed in the center of the upper plane 22, and when the fan of the exhaust means 13 disposed above the hole 33 rotates, smoke and the like flow into the flue 26 from the opening 30. is exhausted.

As shown in FIGS. 2 and 4, the opening 30 is provided in an asymmetric opening shape in the left-right direction and the front-back direction. Specifically, each opening 30 consists of a front opening 30A and a rear opening 30B, the left-right width of the front opening 30A is larger than the left-right width of the rear opening 30B, and the front-to-back length of the rear opening 30B is larger than that of the front opening 30A. The length of each opening 30 is longer than the length of the partial opening 30A, and each opening 30 appears approximately L-shaped when viewed from above.
Note that a filter (not shown) is removably arranged in this opening 30.

Next, the operation of the range hood 10 in this embodiment will be explained.
By turning on a switch on an operation panel (not shown), the fan of the exhaust means 13 rotates, and a suction force is generated at the opening 30.
The smoke, etc. that rises toward the range hood 10 enters the smoke collection part 20, and the smoke, etc. that flows into the inner surface of the front part 17 along the forward-sloping intermediate surface part 19 is horizontally moved by the curved surface of the front part 17. It is turned into a spiral swirling flow (see arrow in FIG. 5) and is sucked into the front opening 30A.
Some of the smoke that has risen into the smoke collecting section 20 spreads to the rear surface section 18 and the side surfaces 15 and 16 and flows, but the smoke that has flowed into the inner surface of the rear surface section 18 is turned into a swirling flow there. (See the arrow in FIG. 5) and is sucked by the suction force of the rear opening 30B. Further, the flow toward the side surfaces 15 and 16 is also sucked by the rear opening 30B.
As described above, in the range hood 10 according to the present embodiment, smoke flowing toward the front portion 17 is sucked in through the front opening 30A, and smoke flowing elsewhere is sucked and exhausted through the rear opening 30B. There is.

When cleaning the range hood 10, the intermediate surface portion 19 may be rotated in the direction of arrow A in FIG. 1 using the hinge portion 19A as a fulcrum by releasing an engaging portion (not shown) on the rear end side. Thereby, the inner surface of the intermediate surface portion 19 can be cleaned, and the oil tray 24 can also be cleaned if necessary.

Therefore, according to the present embodiment, a swirling flow of smoke and the like can be generated inside each of the front and rear sides of the hood body 11 and this can be sucked, so that smoke and the like can be exhausted without leaking to the outside of the hood body 11.
Furthermore, since there is no need to provide openings in the side surfaces 15 and 16, the hood main body 11 can be made thinner.
Furthermore, since the front opening 30A has a relatively large opening width, combined with the configuration that forms a swirling flow in the front inside the hood main body 11, it is possible to reliably suck smoke, etc. and avoid smoke leakage to the outside. can.
Furthermore, since the number of filters covering the pair of left and right openings can be reduced to two, cleaning performance can be improved and cost reduction can be expected.
Furthermore, by providing the flue with a narrower width toward the rear, its planar area becomes smaller, and the inside of the flue can be easily cleaned. Moreover, in a configuration in which the exhaust means is arranged directly above the flue, the distance between the opening and the exhaust means is shortened, and as a result, the area or area on which oil stains adhere becomes smaller, reducing the burden of cleaning. be able to.
