Description

  The present invention relates to a range hood, and more particularly, to a side draft type range hood.

  Conventionally, a side draft type range hood with a rectifying plate whose suction surface is not horizontal has been proposed. A side draft type range hood with a rectifying plate is inclined such that the inner panel of the range hood and the rectifying plate facing it are high on one side (for example, the front side) and low on the other side (for example, the back side). It is a type of range hood that sucks oil smoke and the like generated by cooking etc. from the side. In addition, such a range hood is divided into a range hood that sucks oil smoke generated from the cooking device from four sides of the rectifying plate, and a range hood in which the lower side of the rectifying plate is blocked by an oil receiver or the like and sucks from the remaining three sides.

However, in the former range hood that sucks in air from the four sides of the current plate, the suction force is weak at locations away from the opening, for example, near the corners of the current plate, depending on the position of the opening communicating with the blower provided on the inner panel. , Oil smoke may not be captured. In addition, in the latter range hood that sucks air from the three sides of the rectifying plate, the smoke smoke rising from the cooker is blocked at the lower inlet of the rectifying plate that is closest to the first, so I can't inhale. Although it can also inhale from the suction port on the other side, the suction direction of the other suction port is different from the direction in which the oil smoke rises, and the suction efficiency is poor. For this reason, the oily smoke that could have been captured had escaped.
Therefore, the present invention provides a range hood that enhances the suction performance to capture more oil smoke and collects the captured oil in an oil receiver in a side draft type range hood with a rectifying plate.

In order to solve the above-mentioned problem, an inner surface panel provided on the inner surface of the hood and having an opening for sucking air, and a rectifying plate that is opposed to the inner surface panel and is attached so as to cover the opening, are installed. At this time, one end of the inner surface panel and one end of the rectifying plate corresponding to one end of the inner surface panel are respectively higher than the other end of the inner surface panel and the other end of the rectifying plate corresponding to the other end of the inner surface panel. In addition, the range hood further includes an air volume suppressing portion that narrows a gap between the rectifying plate and the inner surface panel on a part of the other end side of the rectifying plate or the other end of the inner surface panel, and a side of the other end of the rectifying plate Or a range hood provided with the oil receiving part which is provided in the other end side of an inner surface panel and has a width larger than the width of the other end of a current plate is provided.
According to this, the flow rate of the air at the lower side, which is the other end of the rectifying plate, is suppressed, so that the force for sucking in air is distributed to other parts, thereby sucking in positions other than the air volume restraining part. The range hood which improved performance and secured the force which inhales oil smoke also in the suction port in the position away from the opening part can be provided.

Further, the air volume suppressing part may be a bulging part in which the inner surface panel bulges toward the rectifying plate at a position corresponding to the central part on the other end side of the rectifying plate.
According to this, both ends of the lower side which is the other end of the rectifying plate are arranged in the vicinity of the cooker, and since the force to be sucked into the periphery of both ends is concentrated, the oil smoke can be sucked before spreading and cooking. The oil smoke can be captured more efficiently near the container, and the suction performance can be improved without increasing the number of parts. Therefore, the suction performance can be improved at a low cost. Moreover, since the bulging part is provided seamlessly with the inner panel by pressing or the like, the cleaning property is good.

Furthermore, the width on the other end side of the inner surface panel in the bulging portion may be smaller than the width of the oil receiving portion.
According to this, the oil adhering to an inner surface panel etc. can be poured to an oil receiving part along a bulging part.

Furthermore, the bulging part may be covered with a current plate.
According to this, since it becomes difficult for oil smoke to contact the bulging portion, the bulging portion is easy to clean, and the bulging portion is hidden by the rectifying plate and is not visible to the user, so the design of the range hood is good .

Furthermore, the air volume suppression unit may be characterized in that the rectifying plate is a flange that rises toward the inner surface panel at the center of the other end of the rectifying plate.
According to this, both ends of the lower side which is the other end of the rectifying plate are arranged in the vicinity of the cooker, and since the force to be sucked into the periphery of both ends is concentrated, the oil smoke can be sucked before spreading and cooking. The oil smoke can be captured more efficiently near the container, and the suction performance can be improved without increasing the number of parts. Therefore, the suction performance can be improved at a low cost.

Furthermore, an oil receiving portion may be provided vertically below the other end of the current plate.
According to this, when the oil captured by the baffle plate dripped, the oil receiving portion can reliably receive the oil.

Furthermore, the other end of the inner surface panel may include a guide flange portion that guides the oil attached to the back side to the oil receiving portion.
According to this, since the oil is easily cut by the guide flange portion, the oil is guided toward the oil receiving portion, and the oil surely 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 shorter than the width of the oil receiving portion in the same direction.
According to this, even when the range hood is inclined and installed, the oil guided to the guide flange portion can be reliably dropped onto the oil receiving portion.

Furthermore, the inner surface panel has a mounted portion to which the mounting portion of the rectifying plate is attached. When the air volume suppressing portion is provided on the inner surface panel, the mounted portion is provided in the air volume suppressing portion, and the air volume suppressing portion is the rectifying plate. In the case where the mounting portion is provided, the mounting portion may be provided in the air volume suppressing portion.
According to this, since it is difficult for air to pass near the air volume suppression part, it is difficult for oil to adhere to the attachment part or the attachment part, and therefore it is possible to prevent oil from adhering to the attachment part or the attachment part. Easy to attach and detach, and easy to clean.

Furthermore, the range hood includes a blower box including a fan casing therein, the fan casing has a fan casing oil drain hole that guides oil adhering to the inside of the fan casing downward, and the fan box drains the fan casing oil. There is a blower box oil drain hole that guides the oil dropped from the hole and the oil adhering to the inside of the blower box further downward, and the front side end of the blower box oil drain hole is the back side end of the filter fitted in the opening It is good also for the back side edge part of a fan box oil drain hole to be located in the front side rather than the back side edge part of an oil receiving part.
According to this, when oil dripped from a fan casing oil drain hole or a fan box oil drain hole, oil can be reliably guided to an oil receiving part.

  As described above, according to the present invention, in the range hood with a side draft type rectifying plate, the range hood that improves the suction performance to capture more oil smoke and collects the captured oil in the oil receiver. provide

Hereinafter, each example will be described with reference to the drawings.
<First Example>
With reference to FIG. 1 thru | or FIG. 7, the range hood 100 which concerns on a present Example is demonstrated. The range hood 100 is installed above or to the side of a cooking device on which a pan or frying pan is placed for cooking, collects oil smoke or steam generated by cooking, collects the oil, and cleans the oil. It is a so-called side draft type range hood that exhausts fresh air outdoors. The range hood 100 includes an inner surface panel 20 provided on the inner surface of the hood 10 for collecting oil smoke and the like, a rectifying plate 30 that opposes the inner surface panel 20 and improves the collection efficiency, and a component for collecting oil. An oil receiver 40 and a blower 52 that sucks and exhausts air are provided, and the inner panel 20 and the current plate 30 are installed so as to be higher on the front side and lower on the rear side.

  Here, a side draft type range hood will be described with reference to FIG. The normal range hood has the inner panel and the rectifying plate facing it almost horizontally, whereas the side draft type range hood has the inner panel and the rectifying plate facing the front side (there are users) It is inclined so that it is high on the side) and low on the back side (the back side where there is mainly a wall or the like). This figure (A) is a schematic diagram of the range hood 100 of the present embodiment. In the range hood 100, the flat main portion of the inner surface panel 20 and the current plate 30 are 45 ° to the horizontal plane. The slope is made. That is, when the front side is one end side and the back side is the other end side, one end 20U of the inner panel 20 and one end 30U of the rectifying plate 30 corresponding to one end 20U of the inner panel 20 are the other end 20D of the inner panel 20 and The other end 30 </ b> D of the rectifying plate 30 corresponding to the other end 20 </ b> D of the inner surface panel 20 is at a higher position.

  When the range hood 100 is used, the other side 20 </ b> D of the inner surface panel 20 and the current plate 30, such as oil smoke on the back side (back side of the cooking device) generated by cooking, are relatively close to the frying pan and at a low position. It is sucked from the gap between the ends 30D. On the other hand, oil smoke or the like on the front side (the front side of the cooking device) is sucked from a gap between one end 20U of the inner surface panel 20 and one end 30U of the rectifying plate 30 that is relatively far from the frying pan and at a high position. Of course, oil smoke generated near the right side or the left side of the cooker is from the gap between the right edge of the inner panel 20 and the right edge of the rectifying plate 30, and the left edge of the inner panel 20 and the left edge of the rectifying plate 30. It is sucked from the gap between.

  This figure (B) has shown the range hood which the inner surface panel 20 'and the baffle plate 30' make | form the inclination of 30 degrees with respect to a horizontal surface. Similarly, also in this range hood, one end 20U ′ of the inner panel 20 ′ and one end 30U ′ of the rectifying plate 30 ′ corresponding to one end 20U ′ of the inner panel 20 ′ are connected to the other end 20D ′ of the inner panel 20 ′ and the other end 20D ′. The other end 30D ′ of the rectifying plate 30 ′ corresponding to the other end 20D ′ of the inner panel 20 ′ is at a higher position. And the backside oil smoke or the like is sucked from a gap between the other end 20D 'of the inner panel 20' and the other end 30D 'of the rectifying plate 30', which is relatively close to the frying pan. On the other hand, oil smoke or the like on the front side is sucked from a gap between one end 20U 'of the inner surface panel 20' and one end 30U 'of the rectifying plate 30', which is relatively far from the frying pan.

  This figure (C) shows the range hood in which the inner panel 20 ″ and the current plate 30 ″ are inclined by 90 ° with respect to the horizontal plane. Similarly, also in this range hood, one end 20U ″ of the inner panel 20 ″ and one end 30U ″ of the rectifying plate 30 ″ corresponding to one end 20U ″ of the inner panel 20 ″ are connected to the inner panel 20 ′. The other end 20D ″ and the other end 30D ″ of the rectifying plate 30 ″ corresponding to the other end 20D ″ of the inner surface panel 20 ″ are respectively positioned higher. And the backside oil smoke etc. is sucked from the gap between the other end 20D ″ of the inner panel 20 ″ and the other end 30D ″ of the rectifying plate 30 ″ which is relatively close to the frying pan and at a low position. The On the other hand, oil smoke or the like on the front side is sucked from a gap between the one end 20U ″ of the inner surface panel 20 ″ and the one end 30U ″ of the rectifying plate 30 ″, which is relatively far from the frying pan.

  Thus, the side draft type range hood literally sucks oil smoke or the like from the lateral direction (from the side), and the inner panel 20 ′ and the current plate 30 ′ are approximately 30 ° to 90 ° with respect to the horizontal plane. It has an inclination. In the case of a side-draft type range hood, oil smoke on the back side is sucked in before being diffused at a low position near the cooker, so the collection efficiency is high, and oil smoke on the front side is far from the cooker. Therefore, the collection efficiency tends to be low. Therefore, in the side draft type range hood, the suction efficiency of the air sucked from the blower is arranged in a balanced manner as much as possible in the gap (suction port) between the current plate and the inner panel, thereby improving the collection efficiency as a whole. Is a problem. Further, in the side draft type range hood, since the inner panel and the current plate are inclined, the attached oil component flows to the lower side, but it is a problem to appropriately collect the oil component.

  The range hood 100 is a side draft type range hood as described above, and includes a hood 10 having a blower box 50 therein, an inner panel 20 provided on the inner surface of the hood 10 and having an opening 22 for sucking air. The rectifying plate 30 that is opposed to the inner surface panel 20 and is attached so as to cover the opening 22, and the inner surface of the inner surface panel 20 that is positioned on the lower side of the other end 20D side or the other end 30D side of the rectifying plate 30 The panel 20 bulges toward the rectifying plate 30 at a position corresponding to the central portion (front view) in the left-right direction on the other end 30D side of the rectifying plate 30, and the inner panel 20 positioned at the lower side. The oil receiving portion 40 is provided on the other end 20D side or the other end 30D side of the rectifying plate 30 and has a width larger than the width of the other end 30D of the rectifying plate 30. In addition, the range hood 100 is further provided with an operation unit 70 for turning the range hood 100 on and off by the user on the most front side portion of the inner panel 20 and an illumination unit for brightening the cooking. 71.

  As shown in FIG. 6, the hood 10 has a blower box 50 on the back side of the inside, sucks air from the opening 22 of the inner surface panel 20, covers the duct cover 80, and is connected to the duct mounting portion 81 ( Exhaust to (not shown). The blower box 50 has a fan casing 51 inside, and the fan casing 51 has a blower 52 that generates an air flow inside. As shown in FIGS. 3B, 4 and 6, etc., the inner panel 20 has a concave shape that is recessed to the extent that the current plate 30 can be accommodated from the edge toward the blower box 50 toward the center portion. The periphery of the opening 22 has a flat shape so as to be parallel to the rectifying plate 30. As described above, the flat main portion around the opening 22 of the inner surface panel 20 is inclined so as to be lowered from the front side to the back side at an angle of 45 ° with respect to the horizontal plane, and thus the rectifying plate 30. Similarly, it is inclined so as to be lowered 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 that removes oil and fat from the oil smoke, and the oil and fat removed here is collected in the oil receiver 40 by a method described later.

  The rectifying plate 30 basically forms a gap between the inner panel 20 and the edge of the inner surface panel 20 to increase the flow rate of air at that portion, thereby facilitating the suction of air. Thereby, the collection efficiency of the range hood 100 improves. As shown in FIGS. 4 and 5, the rectifying plate 30 is formed by engaging the engaging portion 31 with the engaged portion 24 provided on the inner surface panel 20 at one end 30 </ b> U of the rectifying plate 30. The attachment portion 32 is attached to the attachment portion 25 provided on the inner surface panel 20 at the other end 30 </ b> D of the member 30, thereby being coupled to the inner surface panel 20. In addition, the to-be-attached part 25 is provided in the bulging part 21, contains a magnet, and attaches the metal rectifying plate 30 by magnetic force.

  The bulging portion 21 is formed by bulging the inner surface panel 20 toward the rectifying plate 30 by integral molding with the inner surface panel 20. The bulging portion 21 is formed at a position on the other end 30 </ b> D side of the rectifying plate 30. By bulging from the inner surface panel 20 toward the rectifying plate 30 in the vicinity of the lower side that is the other end 30D of the rectifying plate 30, the rectifying plate 30 and the inner surface panel 20 are partially disposed on the other end 30D side of the rectifying plate 30. The interval between them is narrowed, making it difficult for air to flow and suppressing the flow rate. As described above, the flow rate of the air on the lower side which is the other end 30D of the rectifying plate 30 is suppressed, so that the force for sucking air is distributed to the other portions. The range hood 100 can be provided in which the ability to suck in oily smoke is secured even at the suction port located away from the opening 22. The bulging portion 21 may be provided by attaching another member to the inner surface panel 20, but it is preferable to provide the bulging portion 21 seamlessly with the inner surface panel 20 by pressing so as to improve cleanability.

  Moreover, in the range hood 100 of the present embodiment, the bulging portion 21 is a central portion in the left-right direction on the side of the other end 30D of the rectifying plate 30 (below the opening 22 located substantially at the center of the inner surface panel 20). Is formed at a position corresponding to. Thereby, as shown to FIG. 2 (A), the both ends of the other end 30D side of the baffle plate 30 will be located just above the stove of a normal cooker. Thus, the both ends of the lower side which is the other end 30D of the rectifying plate 30 are arranged in the vicinity of the cooker, and since the concentration of the sucking force is concentrated around the both ends, the oil smoke can be sucked before spreading, Oil smoke can be captured more efficiently near the cooker. In addition, since it is produced by bulging by press working or the like, the suction performance can be improved without increasing the number of parts, so the suction performance can be improved at a low cost.

  Further, as shown in FIG. 1 (A) and FIG. 4 (A), and FIG. 3 (B) and FIG. 4 (C), the bulging portion 21 is covered with a current plate 30. As described above, since the oil smoke is less likely to contact the bulging portion 21, the bulging portion 21 is easy to clean, and the bulging portion 21 is hidden by the rectifying plate 30 and is not visible to the user. Good design.

  The oil receiver 40 is provided on the other end 20D side of the inner panel 20 positioned on the lower side or the other end 30D side of the rectifying plate 30 and has a width larger than the width of the other end 30D of the rectifying plate 30. Oil smoke or the like generated by cooking is sucked as shown in FIG. 2A and adheres to a part of the inner panel 20 such as the oil adhesion region OZ shown in FIG. 4A. A portion where more oil adheres in the oil adhesion region OZ is around the edge of the current plate 30. When the oil component adheres to these portions, the inner surface panel 20 is inclined, so that the oil component flows toward the other end 20D of the inner surface 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 rectifying plate 30, so that the oil component that has adhered and flowed downward is appropriately collected. be able to. In addition, the oil receiving part 40 is provided with the monitoring window 41 in the front side center part, and the user can monitor the oil accumulation condition.

  Further, the lateral width (in front view) of the bulging portion 21 on the side of the other end 20 </ b> D of the inner surface panel 20, that is, the lateral width of the lowest portion of the bulging portion 21 is smaller than the lateral width of the oil receiver 40. The oil adhering to the filter 60 flows toward the lower part of the filter 60 itself, and flows so as to pass by the side of the bulging portion 21 like the oil content OL shown in FIG. 40 is reached. According to this, the oil component adhering to the inner surface panel 20 or the like can be caused to flow along the bulging portion 21 to the oil receiving portion 40.

  With reference to FIG. 7, the vicinity of the other end 20 </ b> D of the inner panel 20 and the other end 30 </ b> D of the rectifying plate 30, which are the lower part of the range hood 100, will be described. The inner surface panel 20 has a bulging portion 21 that is integrally formed and bulges toward the rectifying plate 30 from the same surface as the opening 22 into which the filter 60 is fitted, and narrows the interval between the rectifying plate 30 and the inner surface panel 20. In this embodiment, the bulging portion 21 is formed at a position corresponding to the central portion on the other end 30 </ b> D side of the rectifying plate 30. The other end 30 </ b> D of the rectifying plate 30 is bent in a U shape, and its end portion is formed as an attachment portion 32. The attachment portion 32 is attached to the attached portion 25 of the magnet by a magnetic force.

  The current plate 30 has a flange 33 having a height lower than that of the attachment portion 32. The flange 33 exists at the same height all around the current plate 30. As shown in this figure, there is only a slight gap between the bulging portion 21 and the flange 33 that is the portion closest to the inner surface panel 20 of the rectifying plate 30 except for the attachment portion 32. On the other hand, in the portion other than the central portion in the left-right direction shown in this figure, the bulging portion 21 does not exist, and thus a gap corresponding to that is secured. The bulging portion 21 functions as a portion that suppresses the air volume by narrowing the distance between the rectifying plate 30 and the inner surface panel 20 at the center of the other end 30D of the rectifying plate 30 and the other end 20D of the inner surface panel 20. As described above, the flow rate of the air on the lower side which is the other end 30D of the rectifying plate 30 is suppressed, so that the force for sucking air is distributed to the other portions. The range hood 100 which has improved the suction performance of the oil and has secured the force to suck in the oil smoke at the suction port in the gap between the one end 20U of the inner panel 20 and the one end 30U of the rectifying plate 30, for example. Can provide.

  The other end 30 </ b> D which is the lowermost end of the rectifying plate 30 is a portion where the oil adhering to the rectifying plate 30 flows and the oil drops downward. Therefore, the front end portion 42 of the oil receiving portion 40 is on the front side (the left side in the drawing) from the other end 30D of the rectifying plate 30, and the rear end portion of the oil receiving portion 40 is on the back side (the other end 30D of the rectifying plate 30). It is preferable that the oil receiving portion 40 is provided on the right side of the drawing, that is, vertically below the other end 30 </ b> D of the rectifying plate 30. According to this, when the oil captured by the baffle plate 30 dripped, the oil receiving part 40 can receive oil reliably.

  The fan casing 51 also has a fan casing oil drain hole 53 that guides oil attached to the inside of the blower 52 and the fan casing 51 downward. The blower box 50 has a blower box oil drain hole 54 that guides oil dropped from the fan casing oil drain hole 53 and oil attached to the inside of the blower box 50 further downward. The front side end of the blower box oil drain hole 54 is located on the back side of the back side end of the filter 60 fitted in the opening 22, and the rear side end of the blower box oil drain hole 54 is oil receiving. It is located on the front side from the back side end of the portion 40. The oil dripped from the blower box oil drain hole 54 adheres to the inner panel 20 on the back side and flows further downward. The other end 20 </ b> D of the inner panel 20 includes a substantially horizontal guide flange portion 23 that guides the oil that has flowed in this way and has adhered to the back side of the inner panel 20 to the oil receiver 40. Such a guide flange portion 23 makes it easy to run out of oil. As described above, the oil is easily cut by the guide flange portion 23, so that the oil is guided toward the oil receiver 40 and the oil surely falls to the oil receiver 40.

  As shown in FIG. 8, the guide flange portion side end portion 26 located at the left and right end portions of the guide flange portion 23 in front view is fitted with an oil receiving portion for fitting an oil receiving portion 40 vacated in the inner surface panel 20. It is provided on the center side from the oil receiving portion fitting portion side end portion 28 at the position of the left and right end portions of the joint portion 27 when viewed from the front. That is, the width of the guide flange portion 23 in the left-right direction in the front view is shorter than the width in the left-right direction in the front view of the oil receiver 40. In addition, the width | variety of the oil receiving part 40 in the front view left-right direction means the width | variety larger than the width | variety of other end 30D of the baffle plate 30 which the oil receiving part 40 has. Therefore, in other words, the width of the guide flange portion 23 in the direction of the larger width of the oil receiving portion 40 is shorter than the width of the oil receiving portion 40 in the same direction. As a result, even when the range hood 100 is inclined and installed, the oil guided to the guide flange portion 23 can be reliably dropped onto the oil receiving portion 40.

<Second Example>
A range hood 100A according to the present embodiment will be described with reference to FIGS. In order to avoid repeated description, the same components as those in the above embodiment are denoted by the same reference numerals, description thereof is omitted, and different portions are mainly described. The range 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 that is higher at the other end 30D that is the lowermost end of the rectifying plate 30A and is higher than the flange 33 of the other portion, and that rises toward the inner surface panel 20A at the center.

  On the other hand, the inner panel 20A does not have the bulging portion 21 that was present in the inner panel 20 of the above-described embodiment. That is, the inner surface panel 20A has a concave shape that is recessed to the extent that the rectifying plate 30 can be accommodated from the edges of all four circumferences toward the central portion including the other end 20D side of the inner surface panel 20A. That is, in the said Example, although the inner surface panel 20 had the bulging part 21, it functioned as the airflow suppression part which narrows the space | interval between the rectifying plate 30 and the inner surface panel 20, but in this embodiment, the rectifying plate Since 30A has the flange 33A, it functions as an airflow suppression unit that narrows the gap between the current plate 30A and the inner panel 20A.

Further, in order to function as an airflow suppression unit that narrows the gap 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 the other end 30D of the rectifying plate 30A is more than the others. By forming the flange 33A having a high height, the suction performance can be improved without increasing the number of parts, and the suction performance can be improved at a low cost, which is preferable. The flange 33A is formed to have a height higher than that of the flange 33 at other portions, but is not limited to this. For example, the other end of the current plate is bent toward the inner panel by pressing or the like. The air volume control unit may be used. The rectifying plate 30A has a mounting portion 32A that is bent and provided so as to face the mounted portion 25A provided on the inner panel 20A from the tip of the flange 33A.

  As in the above embodiment, the inner surface panel 20 has the attached portion 25 to which the attachment portion 32 of the rectifying plate 30 is attached, and when the bulging portion 21 (air flow suppressing portion) is provided on the inner surface panel 20, The mounting portion 25 is provided in the bulging portion 21 (air flow suppression portion), and the inner panel 20A has a mounted portion 25A to which the mounting portion 32A of the rectifying plate 30A is mounted as in this embodiment, and the flange 33A ( In the case where the airflow suppression portion) is provided on the rectifying plate 30A, the attachment portion 32A may be provided on the flange 33A (airflow suppression portion). According to this, since it is difficult for air to pass near the air volume suppression part, it is difficult for oil to adhere to the attachment part or the attachment part, and therefore it is possible to prevent oil from adhering to the attachment part or the attachment part. Easy to attach and detach, and easy to clean.

  In addition, this invention is not limited to the illustrated Example, The implementation by the structure of the range which does not deviate from the content described in each item of a claim is possible. That is, although the present invention has been particularly illustrated and described with respect to particular embodiments, it should be understood that the present invention has been described in terms of quantity, quantity, and amount without departing from the scope and spirit of the present invention. Various modifications can be made by those skilled in the art in application examples and other detailed configurations.

  For example, the airflow suppression portion is provided in the inner panel 20 in the first embodiment and in the rectifying plate 30A in the second embodiment, but is not limited to this, and the other end of the rectifying plate has a higher flange than the others. In addition, an air volume suppressing portion may be provided on both the inner surface panel and the rectifying plate such that the bulging portion is provided at a position corresponding to the high flange of the inner surface panel.
