Description

Smoke exhaust ventilator

Technical Field

The invention relates to a range hood, in particular to a side-draft range hood.

Background

A side-suction type range hood with a rectifying plate, in which the suction surface is not horizontal, has been proposed. A side-draft range hood with a flow regulation plate is a range hood in which an inner panel of the range hood and the flow regulation plate opposed thereto are inclined so as to be high on one side (for example, a front side) and low on the other side (for example, a rear side), and rising oil smoke or the like generated by cooking or the like is sucked in a lateral direction. Such a range hood is classified into a range hood that sucks the soot generated from the cooker from four sides of the rectifying plate and a range hood that sucks the soot from the remaining three sides while blocking the lower side of the rectifying plate with an oil receiving box or the like.

Disclosure of Invention

Problems to be solved by the invention

However, in the case of the hood that sucks air from the four sides of the flow regulating plate in the past, depending on the position of the opening that communicates with the blower provided in the inner panel, the force of suction is weak at a portion away from the opening, for example, near the corner of the flow regulating plate, and therefore soot may not be captured. In the range hood that sucks air from three sides of the flow regulating plate, the suction port at the lower side of the flow regulating plate, where the oil smoke rising from the cooking device first approaches, is blocked, and therefore the oil smoke cannot be sucked from the lower side. Although the oil smoke can be sucked from the suction ports on the other sides, the suction direction of the other suction ports is different from the direction in which the oil smoke rises, and the suction efficiency is poor. This results in the escape of the oil vapour that should be captured.

Accordingly, an object of the present invention is to provide a side-suction type range hood with a flow regulating plate, which can capture more soot by improving suction performance and recover the captured oil to an oil receiving box.

Means for solving the problems

In order to solve the above problem, a range hood is provided, which comprises an inner panel, an opening part and a fan, wherein the inner panel is arranged on the inner surface of a cover and is provided with an air suction opening part; and a rectifying plate opposed to the inner panel and installed in a manner of covering the opening portion, wherein when the range hood is installed, one end of the inner panel and one end of the rectifying plate corresponding to one end of the inner panel are located at a high position respectively for the other end of the inner panel and the other end of the rectifying plate corresponding to the other end of the inner panel, and wherein the range hood further includes: an air volume suppressing part which reduces the distance between the rectifying plate and the inner panel at the other end side of the rectifying plate or a part of the other end side of the inner panel; and an oil receiving portion provided at the other end side of the flow regulating plate or the other end side of the inner panel and having a width larger than that of the other end of the flow regulating plate.

Accordingly, the following range hood can be provided: since the flow rate of air is suppressed in a part of the lower edge of the other end of the flow regulating plate, the force of sucking air is dispersed in other parts, thereby improving the suction performance in positions other than the air flow suppressing part and ensuring the force of sucking soot in the suction port located at a position away from the opening.

The air volume suppressing portion may be a raised portion in which the inner panel is raised toward the rectifying plate at a position corresponding to a central portion of the other end side of the rectifying plate.

Accordingly, the two end portions of the lower edge as the other end of the rectifying plate are disposed in the vicinity of the cooking device, and the suction force is concentrated on the periphery of the two end portions, so that the cooking fume can be sucked before being diffused, the cooking fume can be efficiently captured in the vicinity of the cooking device, and the suction performance can be improved without increasing the number of components, so that the suction performance can be improved at low cost. Further, since the raised portion is provided by press working or the like so as to be seamless with the inner panel, the cleanability is good.

Further, the width of the other end side of the inner panel in the ridge portion may be smaller than the width of the oil receiving portion.

Accordingly, the oil adhering to the inner panel or the like can be made to flow to the oil receiving portion along the ridge portion.

Further, it may be characterized in that the bulge portion is covered with the current plate.

Accordingly, the protruding portion is less likely to be touched by soot, so that the protruding portion is excellent in cleanability, and the protruding portion is shielded by the flow regulating plate so as to be invisible to a user, so that the range hood is excellent in design.

The air volume suppressing portion may be a flange of the rectifying plate rising toward the inner panel at a central portion of the other end of the rectifying plate.

Accordingly, the lower end portion of the second end of the rectifying plate is disposed in the vicinity of the cooking device, and the suction force is concentrated on the periphery of the lower end portion, so that the soot can be sucked before being diffused, the soot can be captured more efficiently in the vicinity of the cooking device, and the suction performance can be improved without increasing the number of components, thereby improving the suction performance at low cost.

Further, an oil receiving portion may be provided vertically below the other end of the flow regulating plate.

Accordingly, when the oil captured by the rectifying plate drops, the oil receiving portion can reliably receive the oil.

Further, the other end of the inner panel may include a guide flange portion for guiding the oil adhered to the back side to the oil receiving portion.

Accordingly, the oil is easily cut off by the guide flange portion, whereby the oil is guided to the oil receiving portion and the oil reliably falls to the oil receiving portion.

Further, the width of the guide flange portion in the direction of the large width of the oil receiving portion may be smaller than the width of the oil receiving portion in the same direction.

Accordingly, even if the hood is installed obliquely, the oil guided to the guide flange portion can be reliably dropped to the oil receiving portion.

Further, the inner panel may have a mounted portion to which the mounting portion of the rectifying plate is mounted,

when the air volume suppressing portion is provided on the inner panel, the mounted portion is provided on the air volume suppressing portion, and when the air volume suppressing portion is provided on the rectifying plate, the mounting portion is provided on the air volume suppressing portion.

Accordingly, since air is less likely to pass through the vicinity of the air volume suppressing portion, oil is less likely to adhere to the mounting portion or the mounted portion, and thus oil can be prevented from being fixed to the mounting portion or the mounted portion.

The range hood may further include a blower case having a fan cover therein, the fan cover having a fan cover oil discharge hole for guiding oil adhered to the inside of the fan cover downward, the blower case having a blower case oil discharge hole for guiding oil dripping from the fan cover oil discharge hole and oil adhered to the inside of the blower case further downward, a front side end of the blower case oil discharge hole being positioned on a back side of an end of the filter fitted into the opening, and a back side end of the blower case oil discharge hole being positioned on a front side of an end of the filter fitted into the opening.

Accordingly, when oil drips from the fan cover oil drain hole or the blower case oil drain hole, the oil can be reliably guided to the oil receiving portion.

ADVANTAGEOUS EFFECTS OF INVENTION

As described above, according to the present invention, in the side-draft type range hood with a flow regulating plate, the range hood is provided which can capture more soot by improving the suction performance and recover the captured oil to the oil receiving box.

Detailed Description

Hereinafter, embodiments will be described with reference to the drawings.

< first embodiment >

A range hood 100 according to the present embodiment will be described with reference to fig. 1 to 7. The range hood 100 is a so-called side draft range hood that is installed above or at a side of a cooking device on which a pot or a pan is placed to cook, collects oil components such as soot and steam generated by cooking, and discharges clean air from which the oil components are removed to the outside. The range hood 100 includes an inner panel 20 provided on an inner surface of a smoke exhaust hood 10 for collecting oil smoke, etc., a rectifying plate 30 opposed to the inner panel 20 to improve collection efficiency, an oil receiving portion 40 for collecting oil components, and a blower 52 for sucking and discharging air, and the inner panel 20 and the rectifying plate 30 are provided so as to be higher on a front side and lower on a rear side.

Here, the side suction type hood will be explained with reference to fig. 11. In a general range hood, an inner panel and a flow regulating plate opposed thereto are disposed substantially horizontally, and in contrast to this, a side-suction range hood is inclined such that the inner panel or the flow regulating plate opposed thereto is high on the front side (the side where a user is located) and the back side (mainly the back side having a wall or the like) is low. Fig. 11 (a) is a schematic view of the hood 100 of the present embodiment, and in the hood 100, the flat main portion of the inner panel 20 and the flow rectification plate 30 are inclined at 45 ° with respect to the horizontal plane. That is, when the front side is one end side and the back side is the other end side, the one end 20U of the inner panel 20 and the one end 30U of the rectifying plate 30 corresponding to the one end 20U of the inner panel 20 are located at a higher position than the other end 20D of the inner panel 20 and the other end 30D of the rectifying plate 30 corresponding to the other end 20D of the inner panel 20.

When the range hood 100 is used, soot on the back side (the back side of the cooker) generated by cooking is sucked from the gap between the other end 20D of the inner panel 20 and the other end 30D of the flow rectification plate 30, which are located at a position closer to and lower than the pan. Meanwhile, soot and the like on the front side (the front side of the cooker) are sucked from a gap between the one end 20U of the inner panel 20 and the one end 30U of the rectifying plate 30, which are located at a relatively far and high position from the pan. Of course, soot and the like generated in the vicinity of the right or left side of the cooker are sucked from the gap between the right edge of the inner panel 20 and the right edge of the rectification plate 30, and also from the gap between the left edge of the inner panel 20 and the left edge of the rectification plate 30.

Fig. 11 (B) shows a range hood in which the inner panel 20 'and the rectifying plate 30' are inclined at 30 ° with respect to the horizontal plane. Similarly, in this hood, the one end 20U 'of the inner panel 20' and the one end 30U 'of the flow regulating plate 30' corresponding to the one end 20U 'of the inner panel 20' are also located at high positions with respect to the other end 20D 'of the inner panel 20' and the other end 30D 'of the flow regulating plate 30' corresponding to the other end 20D 'of the inner panel 20', respectively. Therefore, the soot and the like on the back surface side are sucked from the gap between the other end 20D 'of the inner panel 20' and the other end 30D 'of the current plate 30', which are located relatively near and low from the pan. Meanwhile, the soot and the like on the front surface side are sucked from the gap between the one end 20U 'of the inner panel 20' and the one end 30U 'of the current plate 30' which are located relatively far and high from the pan.

Fig. 11 (C) shows the hood in which the inner panel 20 "and the rectifying plate 30" are inclined at 90 ° to the horizontal plane. Similarly, in this hood, the one end 20U "of the inner panel 20" and the one end 30U "of the flow regulating plate 30" corresponding to the one end 20U "of the inner panel 20" are also located at high positions with respect to the other end 20D "of the inner panel 20" and the other end 30D "of the flow regulating plate 30" corresponding to the other end 20D "of the inner panel 20", respectively. Therefore, the soot and the like on the back surface side are sucked from the gap between the other end 20D "of the inner panel 20" and the other end 30D "of the current plate 30" which are located relatively near and low from the pan. Meanwhile, the soot and the like on the front surface side are sucked from the gap between the one end 20U "of the inner panel 20" and the one end 30U "of the current plate 30" which are located relatively far and high from the pan.

In this way, the side-suction type range hood sucks oil smoke or the like from the lateral direction (from the side surface) like characters, and the inner panel 20 'and the flow rectification plate 30' are inclined approximately at 30 ° to 90 ° with respect to the horizontal plane. Side draft range hoods tend to: the soot and the like on the back side are sucked before being diffused at a position close to and low from the cooker, and therefore the collection efficiency is high, while the soot and the like on the front side are sucked at a position far from and high from the cooker, and therefore the collection efficiency is low. Therefore, in the side-suction type hood, it is an object to improve the collecting efficiency as a whole by arranging the suction force of the air sucked into the blower in the gap (suction port) between the rectifying plate and the inner panel in a balanced manner as much as possible. In addition, in the side-suction type hood, the inner panel and the rectifying plate are inclined, and therefore, the adhered oil flows to the lower side, but it is a problem to appropriately recover the oil.

The range hood 100 is a side-suction range hood as described above, and includes a smoke exhaust hood 10 having a blower case 50 therein, an inner panel 20 provided on an inner surface of the smoke exhaust hood 10 and having an opening 22 through which air is sucked, a rectifying plate 30 attached to face the inner panel 20 so as to cover the opening 22, a bulging portion 21 bulging toward one side of the rectifying plate 30 at a central portion (front view) in a left-right direction of one side corresponding to the other end 30D of the rectifying plate 30 of the inner panel 20 located on a lower side or a portion of the other end 30D of the rectifying plate 30, and an oil receiving portion 40 provided on the other end 20D side of the inner panel 20 located on the lower side or the other end 30D side of the rectifying plate 30 and having a width larger than that of the other end 30D of the rectifying plate 30. Further, the hood 100 includes an operation portion 70 for turning on/off the hood 100 by a user and an illumination portion 71 for illuminating during cooking, in a portion of the inner panel 20 on the frontmost side.

As shown in fig. 6, the exhaust hood 10 has a blower case 50 on the back side inside, and sucks air from the opening 22 of the inner panel 20 and discharges the air to an air duct (not shown) covered with a duct cover 80 and connected to a duct mounting portion 81. The blower case 50 has a fan cover 51 therein, and the fan cover 51 has a blower 52 therein for generating an air flow. As shown in fig. 3 (B), 4, and 6, the inner panel 20 is recessed from the edge toward the center toward the blower case 50 to such an extent that the rectifying plate 30 can be housed therein, and the periphery of the opening 22 is flat so as to face the rectifying plate 30 and be parallel thereto. As described above, since the flat main portion around the opening 22 of the inner panel 20 is inclined so as to be lower from the front side to the back side at an angle of 45 ° with respect to the horizontal plane, the rectifying plate 30 is also inclined so as to be lower from the front side to the back side at an angle of 45 ° with respect to the horizontal plane. The opening 22 is provided with a filter 60 for removing oil and fat from the soot, and the oil and fat removed here is recovered to the oil receiving portion 40 by a method described later.

The rectifying plate 30 increases the flow rate of air in the portion by forming a gap substantially with the edge portion of the inner panel 20, and thus air is easily sucked. This improves the collection efficiency of the hood 100. As shown in fig. 4 and 5, the engaging portion 31 is engaged with the engaged portion 24 provided on the inner panel 20 at one end 30U of the rectifying plate 30, and the mounting portion 32 is attached to the mounted portion 25 provided on the inner panel 20 at the other end 30D of the rectifying plate 30, whereby the rectifying plate 30 is coupled to the inner panel 20. The attached portion 25 is provided on the ridge portion 21, includes a magnet, and is attached with a metal rectifying plate 30 by magnetic force.

The bulge portion 21 is formed by being integrally formed with the inner panel 20, and the inner panel 20 bulges toward the rectifying plate 30. The bulge portion 21 is formed at a position on one side of the other end 30D of the rectifying plate 30. The lower edge of the other end 30D of the baffle plate 30 is raised from the inner panel 20 toward the baffle plate 30, so that the distance between the baffle plate 30 and the inner panel 20 is reduced at a part of the other end 30D of the baffle plate 30, and the air is prevented from flowing easily and the flow rate is suppressed. In this manner, the following range hood 100 can be provided: by suppressing the flow rate of air that is a part of the lower edge of the other end 30D of the flow regulating plate 30, the force of the sucked air is dispersed in other parts, thereby improving the suction performance at positions other than the bulge portion 21 and ensuring the force of sucking the soot also in the suction port located at a position distant from the opening portion 22. The raised portion 21 can be provided by attaching another member to the inner panel 20, but it is preferable to provide the raised portion without a seam with the inner panel 20 by press working because the cleaning property is good.

In the hood 100 of the present embodiment, the bulge portion 21 is formed at a position corresponding to the center portion in the left-right direction of the other end 30D of the rectifying plate 30 (located in the vicinity of the lower side of the opening 22 at the substantially center of the inner panel 20). Thus, as shown in fig. 2 (a), both end portions on one side of the other end 30D of the rectifying plate 30 are normally located at positions directly above the range of the cooker. As described above, both end portions of the lower edge of the other end 30D of the rectifying plate 30 are disposed near the cooking device, and the force of suction is concentrated on the periphery of both end portions, whereby the soot can be sucked before being diffused, and the soot can be captured more efficiently near the cooking device. Further, since the suction performance can be improved without increasing the number of parts, the suction performance can be improved at low cost.

As can be seen from a comparison between fig. 1 (a) and fig. 4 (a), and fig. 3 (B) and fig. 4 (C), the ridge portion 21 is covered with the rectifying plate 30. In this way, the soot does not easily contact the protruding portion 21, so the protruding portion 21 is good in cleanability, and the protruding portion 21 is shielded by the flow rectification plate 30 and becomes invisible to the user, so the design of the hood 100 is good.

The oil receiving portion 40 is provided on the other end 20D side of the inner panel 20 or the other end 30D side of the flow regulating plate 30 located on the lower side, and has a width larger than the width of the other end 30D of the flow regulating plate 30. Soot and the like generated by cooking are sucked as shown in fig. 2 (a), and are often attached to the portion of the oil adhesion region OZ shown in fig. 4 (a) of the inner panel 20, for example. In the oil adhesion region OZ, a portion where more oil adheres is near the edge of the flow regulating plate 30. When oil adheres to these portions, the inner panel 20 is inclined, and therefore the oil flows toward the other end 20D of the inner panel 20. The oil receiver 40 is provided on the other end 20D side of the inner panel 20 and has a width larger than the width of the other end 30D of the flow regulating plate 30, and therefore oil adhering to and flowing to the lower side can be appropriately recovered. The oil receiver 40 includes a monitoring window 41 in the center of the front side, and the user can monitor the oil storage.

Further, the transverse width (front view) of the other end 20D of the inner panel 20 of the raised portion 21, that is, the lowermost transverse width of the raised portion 21 is smaller than the transverse width of the oil receiving portion 40. The oil adhered to the filter 60 flows toward the lower side of the filter 60 itself, and flows to reach the oil receiving portion 40 so as to pass through the side surface of the ridge portion 21 as shown in the flow direction OL of the oil in fig. 4 (D). Accordingly, oil adhering to the inner panel 20 and the like can be made to flow to the oil receiving portion 40 along the ridge portion 21.

Referring to fig. 7, the vicinity of the other end 20D of the inner panel 20 and the other end 30D of the flow regulating plate 30, which are located below the hood 100, will be described. The inner panel 20 is integrally formed and raised from the same side facing the flow regulating plate 30 as the opening 22 in which the filter 60 is fitted, and has a raised portion 21 for reducing the distance between the flow regulating plate 30 and the inner panel 20. In the present embodiment, the bulge portion 21 is formed at a position corresponding to the center portion of the other end 30D of the rectifying plate 30. The other end 30D of the rectifying plate 30 is bent in a U-shape, and the end thereof is formed as a mounting portion 32. The mounting portion 32 is mounted to the mounted portion 25 of the magnet by magnetic force.

The current plate 30 has a flange 33 having a height lower than that of the mounting portion 32. The flange 33 is located at the same height over the entire circumference of the rectifying plate 30. As shown in fig. 7, in the portion other than the mounting portion 32, there is only a slight gap between the flange 33, which is the portion of the rectifying plate 30 closest to the inner panel 20, and the ridge portion 21. On the other hand, in the portion other than the central portion in the left-right direction shown in fig. 7, since the ridge portion 21 is not present, a gap corresponding to the amount thereof is secured. The bulge portion 21 functions as a portion for reducing the distance between the rectifying plate 30 and the inner panel 20 in the central portion thereof and suppressing the air volume in the other end 30D of the rectifying plate 30 and the other end 20D of the inner panel 20. In this manner, the following range hood 100 can be provided: by suppressing the flow rate of air that is a part of the lower edge of the other end 30D of the flow regulating plate 30 and dispersing the force of sucked air in other parts, the suction performance at positions other than the bulge portion 21 is improved, and the force of sucking soot is secured also in the suction port located at a position away from the opening portion 22, for example, in the gap between the one end 20U of the inner panel 20 and the one end 30U of the flow regulating plate 30.

The other end 30D, which is the lowermost end of the flow regulating plate 30, is a portion into which oil adhering to the flow regulating plate 30 flows and from which oil drops downward. Therefore, the front end 42 of the oil receiver 40 is located on the front surface side (left side in the drawing) of the other end 30D of the flow regulating plate 30, and the rear end of the oil receiver 40 is located on the rear surface side (right side in the drawing) of the other end 30D of the flow regulating plate 30, that is, the oil receiver 40 is preferably provided vertically below the other end 30D of the flow regulating plate 30. Accordingly, when the oil captured by the flow regulating plate 30 drops, the oil receiving portion 40 can reliably receive the oil.

The fan cover 51 has a fan cover oil drain hole 53 for guiding oil adhered to the inside of the blower 52 or the fan cover 51 downward. Further, blower case 50 has blower case oil drain hole 54 for guiding oil dropping from fan cover oil drain hole 53 and oil adhering to the inside of blower case 50 further downward. The front side end of the blower case oil drain hole 54 is located on the rear side of the rear side end of the filter 60 fitted into the opening 22, and the rear side end of the blower case oil drain hole 54 is located on the front side of the rear side end of the oil receiver 40. The oil dropping from the blower case oil drain hole 54 adheres to the back side of the inner panel 20 and flows further downward. The other end 20D of the inner panel 20 includes a substantially horizontal guide flange portion 23 that guides the oil that has flowed in and adhered to the back side of the inner panel 20 to the oil receiving portion 40. Such a guide flange portion 23 allows oil to be easily cut off. As described above, the oil is easily cut off by the guide flange portion 23, and the oil is guided to the oil receiving portion and reliably falls to the oil receiving portion 40.

As shown in fig. 8, the guide flange part side end 26 located at the front left and right ends of the guide flange part 23 is provided at a position closer to the center side than the oil receiver fitting part side end 28 located at the front left and right ends of the oil receiver fitting part 27 for fitting the hollowed oil receiver 40 into the inner panel 20. That is, the width of the guide flange portion 23 in the right-left direction as viewed from the front is smaller than the width of the oil receiving portion 40 in the right-left direction as viewed from the front. The width of the oil receiving portion 40 in the left-right direction in front view is a width of the oil receiving portion 40 larger than the width of the other end 30D of the flow regulating plate 30. Therefore, in other words, the width of the guide flange portion 23 in the direction of the large width of the oil receiving portion 40 is smaller than the width of the oil receiving portion 40 in the same direction. Accordingly, even when the hood 100 is installed in an inclined manner, the oil guided to the guide flange portion 23 can be reliably dropped to the oil receiving portion 40.

< second embodiment >

A range hood 100A according to the present embodiment will be described with reference to fig. 9 to 10. In order to avoid redundant description, the same components as those of the above embodiment are denoted by the same reference numerals, and description thereof will be omitted, with different portions being mainly described. The hood 100A includes an inner panel 20A provided on the inner surface of the hood 10, and a rectifying plate 30A attached to face the inner panel 20A. The rectifying plate 30A has a flange 33A which is higher than the flange 33 of the portion other than the lowermost end 30D of the rectifying plate 30A and which stands up toward the inner panel 20A at the center portion.

On the other hand, the inner panel 20A does not have the ridge portion 21 present in the inner panel 20 of the above embodiment. That is, the inner panel 20A includes the other end 20D side of the inner panel 20A, and is recessed from the entire peripheral edge toward the center toward the blower case 50 to such an extent that the rectifying plate 30 can be accommodated therein. That is, in the above embodiment, the inner panel 20 has the ridge portion 21 and functions as an air volume suppressing portion for reducing the pitch between the rectifying plate 30 and the inner panel 20, but in the present embodiment, one side of the rectifying plate 30A has the flange 33A and functions as an air volume suppressing portion for reducing the pitch between the rectifying plate 30A and the inner panel 20A. As described above, the two end portions of the lower side of the other end 30D of the rectifying plate 30A are disposed near the cooking device, and the force of suction is concentrated on the periphery of the two end portions, whereby the soot can be sucked before being diffused, and the soot can be captured more efficiently near the cooking device. Further, when the air volume suppressing portion functions to reduce the distance between the rectifying plate 30A and the inner panel 20A, another member may be provided on the other end side of the rectifying plate, but it is preferable to form the flange 33A having a height higher than that of the other member on the other end 30D of the rectifying plate 30A because the suction performance can be improved without increasing the number of members, and therefore, the suction performance can be improved at low cost. The flange 33A is formed to be higher than the height of the flange 33 except for the portion thereof, but is not limited to this, and for example, the other end of the rectifying plate may be bent toward the inner panel by press working or the like to be used as the air volume control portion. The rectifying plate 30A has a mounting portion 32A bent from the front end of the flange 33A so as to face the mounted portion 25A provided on the inner panel 20A.

As in the above-described embodiment, the inner panel 20 has the attached portion 25 to which the attaching portion 32 of the rectifying plate 30 is attached, and when the protruding portion 21 (air volume suppressing portion) is provided on the inner panel 20, the attached portion 25 is provided on the protruding portion 21 (air volume suppressing portion), and in the present embodiment, the inner panel 20A has the attached portion 25A to which the attaching portion 32A of the rectifying plate 30A is attached, and when the flange 33A (air volume suppressing portion) is provided on the rectifying plate 30A, the attaching portion 32A may be provided on the flange 33A (air volume suppressing portion). Accordingly, since air is less likely to pass through the vicinity of the air volume suppressing portion, oil is less likely to adhere to the mounting portion or the mounted portion, and thus oil can be prevented from being fixed to the mounting portion or the mounted portion.

The present invention is not limited to the illustrated embodiments, and can be implemented according to configurations without departing from the scope of the contents described in the items of the claims. That is, although the present invention has been described with reference to specific embodiments, it is to be understood that various modifications can be added to the embodiments described above by those skilled in the art in terms of the number, application examples, and other detailed configurations without departing from the technical spirit and scope of the present invention.

For example, the air volume suppressing portions may be provided on both the inner panel and the flow regulating plate by providing a flange having a height higher than the other height at the other end of the flow regulating plate and providing a protrusion at a position of the inner panel corresponding to the flange having the height, for example, but not limited to, the air volume suppressing portions in the first embodiment are provided on the inner panel 20 and the flow regulating plate 30A in the second embodiment.
