Air conditioner

Technical field

[0001] The present invention relates to an air conditioner capable of efficiently blowing conditioned air far away.

Background art

[0002] When conditioned air is blown out from an indoor unit of an air conditioner, blowing in the horizontal direction forward of the casing during cooling operation and downward in the heating operation is effective for making the temperature distribution in the room uniform. . However, when conditioned air is blown horizontally from the force outlet to the front of the casing, if a disturbance occurs in the air flow, a part of the conditioned air is sucked in from the inlet, resulting in a so-called short circuit. There was a risk of losing.

[0003] In order to solve the above problem, Patent Document 1 discloses that the first panel and the second panel are rotatably attached to the lower edge and the upper edge of the air outlet, respectively, and the directions of the two panels are set.

Disclosure of the invention

Problems to be solved by the invention

[0004] However, in the air conditioner described above, the rotation control of the two panels required to prevent a short circuit is complicated, and the blowout air path is limited to a predetermined range! /, Because of the blowout force, the flow of conditioned air that is blown out is disturbed! This turbulence in the air flow makes it difficult to smoothly send conditioned air far away.

[0005] In addition, in order to send the conditioned air blown in the horizontal direction as far as possible, it is effective to arrange and send out the air flow by making the length of the louver as long as possible to adjust the air flow direction. S, In the above air conditioner, the air blown directly from the outlet The length of the first panel is about the same as the outlet, and there was a problem that it was insufficient to send conditioned air far away. In addition, the lower wall surface from the fan to the air outlet and the shape of the first panel are not continuous, and pressure loss and turbulence occur, so it seems very difficult to send conditioned air far away. It is.

[0006] The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an air conditioner that can efficiently blow out conditioned air to a distant place while suppressing a short circuit. And

Means for solving the problem

[0007] In order to solve the above problems, an air conditioner according to the present invention includes a suction port on an upper surface and a blower outlet on a lower portion of a front surface, and an air flow path extending from the suction port to the blower port. A single fan, a fan for blowing air, and an air guide panel that covers the air outlet and extends upward from the air outlet, and the air guide panel is parallel to the lateral direction of the casing near the lower edge of the air outlet. When the air blower panel is rotated around the set axis of the lower shaft so that the air outlet can be opened and closed, and the air guide panel is rotated to open the air outlet, the fan to the air outlet can be opened. An air guide surface formed in a concave curved surface so as to be continuous with a lower wall surface of the concave curved surface constituting the air flow path is formed on the inner side surface of the air guide panel.

[0008] According to the above configuration, the air guide surface of the cover portion has the lower wall surface when the air guide panel is turned to open the air outlet in order to blow out the conditioned air. Because it is formed in a concave curved shape so as to continue to the air outlet, the direction of the casing does not disturb the flow of conditioned air that blows out along the air flow path formed slightly downward toward the air outlet. It is possible to guide smoothly forward and upward, and it is possible to efficiently blow out conditioned air to a distant place while suppressing a short circuit. Here, the wind guide surface is the surface on the air contact panel where the blowout force comes into contact, that is, the cover where the wind guide panel closes the blowout port. It means the back side of the panel.

[0009] The wind guide panel is composed of a cover panel body that covers the air outlet and an extension panel body that extends the cover panel body, and the cover panel body and the extension panel body are the axes of the lower shaft. It is also possible to adopt a configuration that can be rotated around.

[0010] According to the above configuration, the length of the wind guide panel is equal to the length of the cover panel body and the extension panel body. Since it is formed to be longer, i.e., longer than the length between the lower edge and the upper edge of the air outlet, it is possible to efficiently send conditioned air far away. . Furthermore, since the cover panel body and the extension panel body are composed of separate members, it is possible to change the direction in which air is blown from the air outlet by operating each member separately.

[0011] Specifically, the upper end of the cover panel body can be rotated about the axis of the upper shaft set parallel to the left-right direction of the casing so that the air outlet can be opened and closed. In the configuration described above, the air from the outlet can be blown out of the casing by rotating the cover panel body around the axis of the upper shaft while the extension panel body covers the casing.

[0012] Thereby, conditioned air can be efficiently blown out according to the operation mode. Here, the lower axis is set separately at the lower end of the wind guide panel, and the upper axis is set separately at the upper end of the cover panel body. Both the lower shaft and the upper shaft are set in parallel with the casing left-right direction.

[0013] In addition, when the cover panel body is rotated to take the posture of opening the air outlet, the air from the fan to the air outlet is continuous with the concave curved air guide surface of the cover panel body. If the upper wall surface constituting the flow path is formed, even when air is blown downward from the air outlet, the air flow is not disturbed and conditioned air can be sent smoothly.

[0014] Specifically, the upper wall surface may be formed so as to incline upward from the air flow path toward the air outlet. According to the above configuration, a surface in which the upper wall surface and the concave curved air guide surface of the cover panel body are continuous can be formed, and conditioned air can be sent smoothly.

[0015] Furthermore, the air guide surface of the cover panel body can be formed in a concave curved surface shape, and the air guide surface of the extension panel body can be formed in a convex curved surface shape opposite to the cover panel body. As a result, it becomes possible to correct the direction of the conditioned air that is about to blow out toward the front and slightly above the casing at the part of the cover, so that the short circuit of the conditioned air can be corrected. It becomes possible to suppress more effectively.

[0016] That is, in the present invention, unlike a general louver installed in an air flow so that the air flow is in contact with both surfaces, the wind guide panel is in contact with the air flow surface only on one side. In this case, by curving the air guide surface so that it intervenes in the air flow, the direction of the air guide surface is curved in a direction away from the air flow just by changing the direction of the air flow. It is characterized by the fact that the air flow is guided to the air.

[0017] This is possible because the wind guide surface forms a gentle and smooth curved surface with a concave surface and a convex surface, and the cross section in the length direction of the wind guide surface forms an S-shape. As a result, the air flow flows along the air guide surface without any disturbance.

[0018] According to the present invention, the casing has a gap between the extension panel body and the casing when the cover panel body of the wind guide panel and the extension panel body are in a state of closing the air outlet. It is preferable to have a shape that does not cause a gap. As a result, it is possible to avoid the situation where dust is blown out at the start of the operation of the air conditioner where dust does not accumulate between the extension panel and the casing.

[0019] In order to prevent dust from accumulating between the extension panel body and the casing, the cover panel body of the wind guide panel and the extension panel body are put together so as to close the air outlet. It is also possible to form a protrusion on the casing that closes the gap between the extension panel and the casing.

[0020] Further, when the cover panel body rotates around the upper shaft and takes the posture of opening the air outlet, if there is a gap between the cover panel body and the casing, the surface side of the cover panel body from there Cold air leaks out and the panel body surface cools the casing. There was a problem that when unbalanced humid air came into contact therewith, dew condensation occurred and caused the growth of dirt and germs.

[0021] Therefore, in the present invention, when the cover panel body takes the posture of opening the air outlet, a sealing means for closing the gap between the cover panel body and the casing is provided.

[0022] According to the above configuration, the sealing means closes the gap between the cover panel body and the casing, so that it is possible to effectively prevent the conditioned air from leaking from the gap, and condensation occurs. The air can be efficiently blown out in a desired direction. In this configuration, the cover panel body can close or open the outlet in a state where the extension panel body covers the casing.

[0023] As the sealing means, for example, a gap between the cover panel body and the casing is provided. The sealing material which closes can be arrange | positioned, and the said clearance gap can always be plugged up. Further, as another aspect of the sealing means, as described above, the cover panel has a body strength S, a main body portion that closes the outlet, and a seal portion that extends the main body portion, and the seal portion sandwiches the upper shaft, An abutting portion that is provided on the opposite side of the main body, and that abuts against the seal portion and closes the gap between the seal portion and the casing when the cover panel body is in a posture to open the air outlet. It is also possible to form the sealing means by the sealing portion and the contact portion. As a result, it is possible to reduce the friction S during the rotation of the cover panel as much as possible.

[0024] The contact part may be formed so as to intervene in the rotation trajectory of the seal part. For example, a projecting contact part can be formed on the upper edge or the lower edge of the outlet. In addition, a groove that does not hinder the rotation of the seal part in the left-right direction of the casing is formed above the casing outlet, so that the lower wall part of the groove intervenes and contacts the rotation track of the seal part. It is also possible to set the lower wall portion of the groove portion to function as the contact portion.

[0025] The upper shaft is preferably set at a position above the air outlet. In the above configuration, it is possible to form a portion of the abutting portion where the seal portion directly abuts on the surface on the side opposite to the outlet, whereby the outlet force and the wind pressure of the conditioned air blown from the outlet are separated from the seal portion. It is possible to prevent the conditioned air from leaking more reliably by preventing the direct contact of the contact portion with the contact portion.

[0026] Then, when the cover panel body is rotated around the upper axis and takes a downward posture, at least one of the seal portion and the contact portion is provided with a seal material at a portion where both contact with each other. Even if the cover panel body has stagnation, the gap between the seal portion and the contact portion can be reliably sealed. Therefore, it is possible to effectively prevent the conditioned air from leaking from the gap, and the air can be efficiently blown in a desired direction without causing condensation during the cooling operation.

[0027] Further, in the configuration in which the air guide panel that covers the air outlet and extends upward from the air outlet is rotatable around the lower shaft in the vicinity of the lower end edge of the air outlet, the air guide panel is arranged around the lower shaft. A sealing material that seals a gap between the air guide panel and the casing can be disposed on at least one of the wind guide panel and the casing when the air outlet is rotated to take the posture of opening the air outlet. As a result, conditioned air does not leak from the gap between the wind guide panel and the casing, and the wind guide efficiency is high. The conditioned air can be sent out far along the channel.

[0028] Further, when the wind guide panel is constituted by a cover panel body that covers the air outlet and an extension panel body that extends the cover panel body, at least one of the cover panel body and the extension panel body, A sealing material that seals the gap between the two can be provided. As a result, when the wind guide panel is rotated integrally and the conditioned air is blown forward from the blowout port, the conditioned air is released from the gap between the seal portion of the cover panel body and the extension panel body. The conditioned air can be sent further along the wind guide panel where the air leaks.

[0029] Further, when using a cover panel body having a size that opens and closes the air outlet, such as the wind guide panel in the present invention, if the cover panel body is molded by molding, warping and stagnation are likely to occur. There is a risk of deteriorating the appearance of the air conditioner. Therefore, in the present invention, the wind guide panel is formed in a plate shape, one surface of which forms a wind guide surface, and a reinforcing material can be provided on the wind guide surface side.

[0030] According to the above configuration, it becomes possible to suppress warping and stagnation of the wind guide panel by the reinforcing material, and the reinforcing material is not exposed on the surface of the wind guiding panel. Designability can be maintained. Here, the wind guide surface is the surface of the wind guide panel on the side where the blowout outlet force and the air that is blown out contact, that is, the wind guide panel when the wind guide panel is in an attitude of closing the blowout port. It means the back side.

[0031] The wind guide panel may have a configuration in which a foam layer is laminated on the back surface of a plate-shaped exterior material, and a reinforcing material is embedded in the foam layer. According to the above configuration, since the foam layer is laminated on the exterior material and the reinforcing material is embedded in the foam layer, no condensation occurs on the surface side of the wind guide panel, that is, the surface of the exterior material. Therefore, it is possible to obtain an air conditioner that can achieve both design and function.

[0032] That is, by forming a foam layer having heat insulation properties, it is possible to effectively prevent the occurrence of condensation that is not cooled to the exterior material even when cold air is blown out from the air outlet. It becomes possible.

[0033] Further, by laminating the foam layer on the exterior material, it is possible to force the formation of the one surface side and the other surface side in different shapes. Therefore, the frame material forming one side of the panel is designed with Even when molded visually, the foam layer laminated on the inner surface side can be formed into a desired wind guide shape so that the wind guide direction can be set freely.

[0034] When a foam layer is laminated on an exterior material, a foam material is injected into a mold charged with the exterior material to form a foam, thereby obtaining an air guide panel in which the foam layer is laminated on the exterior material. When it is possible to stack different materials such as S, exterior material and foam layer, warpage and stagnation are likely to occur. In particular, in the wind guide panel, when the length in the width direction is increased with respect to the length direction, warpage and stagnation of the central portion in the width direction tend to increase.

[0035] Therefore, when the foam layer is laminated on the exterior material, the reinforcing material having rigidity is reinforced by injecting the foamed material into the mold together with the exterior material and foaming it. A wind guide panel in which the material is embedded in the foam layer can be obtained, and the appearance and appearance can be maintained by suppressing the warp and stagnation of the wind guide panel.

[0036] Further, the wind guide panel includes a cover panel body that covers the air outlet, and an extended panel body that extends the cover panel body, and the cover panel body and the extended panel body are physically arranged around the lower shaft. In the configuration in which the cover panel body is configured to be rotatable about the upper shaft set in parallel with the left and right direction of the casing so that the air outlet can be opened and closed at the upper end of the cover panel body. It is also possible to embed a reinforcing material at the end of the opposing cover panel body.

[0037] According to the above configuration, even if the extension panel body or the force bar panel body warps or stagnates due to the opening / closing operation of the wind guide panel or changes with time, the original state can be maintained as much as possible by the reinforcing material. It is possible to prevent leakage of conditioned air from the gap between the extension panel body and the cover panel body as well as being aesthetically pleasing. It is also possible to prevent dew condensation and lowering of blowing efficiency.

[0038] Further, when the extension panel body is in a covering posture covering the air outlet, only the cover panel body is rotated around the upper axis and turned downward to blow the air from the air outlet downward. By reinforcing the edge of the panel body with a reinforcing material, it is possible to maintain the aesthetic appearance of the wind guide panel.

[0039] That is, a gap for rotating the cover panel body is required between the extension panel body and the cover panel body. When it becomes larger, this gap has to be set larger, and the large gap between the extension panel body and the cover panel body significantly reduces the appearance design of the wind guide panel.

[0040] Therefore, in the present invention, by reinforcing the end portion of the cover panel body facing the extension panel body as described above with a reinforcing material, distortion such as warpage and stagnation at the end portion is suppressed, It is possible to reduce the gap between the extension panel body and the cover panel body. As a result, it is possible to obtain an air conditioner that enhances the visual unity as a wind guide panel and has a good appearance design.

[0041] Further, if a reinforcing material is also embedded in the end portion of the extension panel body facing the cover panel body, it becomes possible to suppress warping and stagnation of the extension panel body, and the extension panel body, the cover panel body, It is possible to further reduce the gap between the two.

[0042] In the cover panel body, as the position of the upper shaft is closer to the upper end of the cover panel body, the gap between the cover panel body and the extension panel body needs to be set larger. By applying the present invention, The gap between the cover panel body and the extension panel body can be effectively reduced.

[0043] The above reason will be described in detail. FIGS. 14 to 16 are schematic views of the end portions of the cover panel body and the extension panel body facing each other as viewed from the side of the panel. As shown in FIG. 14, the upper shaft formed at the end of the cover panel body 8 when the thickness of the cover panel body 8 and the extension panel body 9 where the cover panel panel 8 has no sag is substantially the same. In order to allow the cover panel body 8 to be rotated around the axis 11a, the clearance between the cover panel body 8 and the extension panel body 9 needs to be XI.

Next, when a stagnation D occurs in the cover panel body 8, as shown in FIG. 15, the cover panel body 8 including the stagnation D portion can be rotated around the axis 11a of the upper shaft. In order to achieve this, the gap between the cover panel body 8 and the extension panel body 9 must be expanded to X2 in consideration of the stagnation D part.

However, even when stagnation D occurs in the cover panel body 8, as shown in FIG. 16, if the distance from the edge of the cover panel body 8 to the axis 11a is increased from Y1 to Y2, the cover panel body The gap between 8 and the extension panel body 9 can be reduced to X3 (X3 <X2) . In other words, the closer the axis 11a is to the edge of the cover panel body, the wider the gap between the cover panel body 8 and the extension panel body 9 is required.

[0046] As the reinforcing material, it is preferable to use a metal material as long as it has higher rigidity than the exterior plate and the foam layer constituting the air guide panel. As the reinforcing material, a shaft, an L-shaped angle, a U-shaped angle, or the like can be used. When the shaft is used as the reinforcing member of the cover panel body, the use of the shaft as the rotating shaft has the advantage that the structure of the cover panel body can be simplified without the necessity of providing a separate rotating shaft.

The invention's effect

[0047] As described above, according to the present invention, the wind guide panel that covers the air outlet and extends upward from the air outlet has the lower shaft that is set in the vicinity of the lower end edge of the air outlet and in parallel with the left-right direction of the casing. A concave curved surface that forms an air flow path from the fan to the air outlet when the air outlet panel is rotated to open and close and the air guide panel rotates to open the air outlet. Since the air guide surface formed in a concave curved surface so as to be continuous with the lower side wall surface is formed on the inner surface of the air guide panel, it is possible to efficiently blow out conditioned air far away by suppressing a short circuit. .

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing an indoor unit of a separate type air conditioner of the present embodiment, and FIG. 2 is a perspective view thereof.

As shown in FIGS. 1 and 2, the indoor unit 1 in this embodiment has an air inlet 3 formed on the upper surface of the casing 2 and an air outlet 4 formed on the lower front of the casing 2. Has been. A heat exchanger 5 is arranged in the internal air flow path 20 of the casing 2 extending from the suction port 3 to the blowout port 4 and is surrounded by the heat exchanger 5 and is composed of a crossflow fan on the blowout port 4 side. Indoor fan 6 is built-in.

[0052] The air outlet 4 is provided with a wind direction changing device 36 comprising a vertical louver 36a and a horizontal louver 36b (see FIG. 3) so that the direction of the air blown from the air outlet 4 can be changed. Have . This wind direction changing device 36 has a known structure. In the present invention, a wind guide panel 7 is provided on the front surface of the casing 2 separately from the wind direction changing device 36.

[0053] The air guide panel 7 is formed so as to cover the blowout port 4 and the upper part thereof from the lower front surface of the casing 2 to the front surface. That is, the air guide panel 7 is formed larger than the air outlet 4 and has a size covering almost the entire front surface of the casing 2. The wind guide panel 7 includes a cover panel body 8 that covers the air outlet 4 and an extension panel body 9 that extends the cover panel body 8 toward the front end side of the wind guide panel.

[0054] Therefore, as described later, when the wind guide panel 7 is rotated to take out the conditioned air to the front, a sufficiently long wind guide surface can be secured, and the conditioned air is distant. Can be sent efficiently. The extension panel body 9 includes an air guide portion 9c that forms an air guide surface and leg portions 9b that extend downward from the lower ends of the left and right side portions of the air guide portion 9c, and is formed in a space between the left and right leg portions 9b. A ventilation portion 9a is formed (see FIGS. 3 and 4).

[0055] The cover panel body 8 has substantially the same length as the air outlet 4, and has the same width as the extension panel body 9. And the wind guide surface 23 of the extension panel body 9 exhibits the function which extends the wind guide surface 22 of the cover panel body 8 (refer FIG. 5).

[0056] A ventilation portion 9a for allowing the air blown from the outlet 4 to pass therethrough is formed in the lower part of the extension panel body 9, and the ventilation portion 9a is approximately the same size as the outlet 4. In this embodiment, a force is formed by forming a notch at the lower end of the extension panel body 9 and using it as the ventilation part 9a. In addition, an opening is formed in the extension panel body 9 and this is used as the ventilation part 9a. Can also

[0057] An extension panel body 9 is disposed on the front side of the outlet 4, and a cover panel body 8 is disposed on the front side thereof. The cover panel body 8 covers not only the ventilation portion 9a of the extension panel body 9, but also the leg portions 9b on both sides of the ventilation portion 9a. That is, the recesses 8a are formed at the left and right end portions of the back surface of the cover panel body 8. When the panel legs 9b are aligned with the recesses 8a and the cover panel body 8 is overlaid on the extension panel body 8, the other state is maintained. It is formed so as to be flush with the part.

[0058] The cover panel body 8 is attached to the extension panel body 9 so as to be rotatable around an axis 11a of the upper shaft 11 provided at the upper end portion of the cover panel body 8. Ie cover Upper shafts 11 are formed in the recesses 8a formed at the left and right ends of the panel body 8 in parallel with the left-right direction of the casing 2, and bearing portions (not shown) are formed on the panel legs 9b. The bearing portion pivotally supports the upper shaft 11 at a position above the upper end of the outlet 4. The upper shaft 11 may be provided on the panel leg portion 9b side, and the bearing portion may be formed on the left and right concave portions 8a side of the cover panel body.

[0059] The cover panel body 8 includes a main body portion 801 that closes the ventilation portion 9a, and a seal portion 802 that extends the main body portion 801. The main body portion 801 and the seal portion 802 sandwich the upper shaft 11a. It is formed to face each other.

[0060] In addition, an air flow path 20 is formed from the indoor fan 6 to the air outlet 4, and a lower side wall surface 21 forming the lower side of the air flow path 20 is inclined downward from the indoor fan 6, The shape is curved so as to be concave downward. On the other hand, the upper wall surface 25 of the air flow path 20 is shaped so as to spread upward from the stabilizer portion to the blower outlet 4 after forming a substantially horizontal portion. The conditioned air from the indoor fan 6 is shaped so as to be blown out efficiently with a pressure loss.

FIG. 3 is a cross-sectional view showing a state in which the cover panel body 8 rotates around the axis 11a of the upper shaft to open the ventilation portion 9a and blows conditioned air downward. It is a perspective view.

In the casing 2, a groove portion 19 is formed in the casing left-right width direction A above the outlet 4. Thereby, when the cover panel body 8 rotates around the axis 11a to open the ventilation portion 9a, the seal portion 802 is prevented from rotating in a direction approaching the casing 2.

[0062] Then, the lower wall portion of the groove portion 19 is set so as to be in contact with the seal portion 802 by intervening in the rotation path of the seal portion 802, and is used as the contact portion 13. In the present embodiment, it is also possible to form a projecting contact portion at the outlet 4 without forming a groove portion 19 in the casing 2 and providing a force groove portion having the lower wall portion as the contact portion 13. .

[0063] The axis 11a of the upper axis of the cover panel body 8 and the seal portion 802 is set at a position higher than the upper end of the air outlet 4 of the casing 2, whereby the seal portion 802 comes into contact with the contact portion 13. The surface can be formed on the surface opposite to the outlet 4. In contact part 13 In this case, a seal material 14 is disposed at a portion where the seal portion 802 contacts. As a result, when the seal portion 802 comes into contact with the contact portion 13, the gap between the two is completely sealed and closed.

[0064] The cover panel body 8 is provided with a fan-shaped gear 15 centered on the upper shaft 11, and when the extension panel body 9 is in contact with the casing, the fan-shaped gear 15 is installed in the casing. The cover panel body 8 is adapted to rotate in mesh with a gear (not shown).

[0065] When the cover panel body 8 rotates so as to open the ventilation portion 9a, the seal portion 802 rotates so that the upper portion 12 of the force bar panel body 8 above the upper shaft 11 approaches the casing 2. To do. Therefore, the upper part of the panel leg portion 9b has a curved shape so as not to interfere with the rotation trajectory of the upper portion 12 of the cover panel body of the seal portion 802.

[0066] The extension panel body 9 is rotatable with respect to the casing 2 around the axis 10a of the lower shaft 10 formed at the lower end of the panel leg 9b. The axis 10a of the lower shaft and the axis 11a of the upper shaft are both arranged such that the axial direction is parallel to the casing left-right direction A.

The air guide shape of the foam layer 912 of the air guide portion 9c is formed in an arc shape so as to warp outward. With this configuration, as will be described later, as shown in FIG. 5, the air guide panel 7 is rotated around the axis 10a of the lower shaft formed at the lower end portions of the panel both end portions 9b, so that the air outlet 4 is formed. When opened, the air blown from the blowout port 4 can be guided toward the room, and a short circuit directed upward of the casing 2 can be prevented.

[0086] The exterior material 911 is made of a synthetic resin and formed into a curved plate shape. Actually, the outer packaging material 91 1 has a U-shaped cross-section with a side wall formed at the periphery, and a foam material is injected into the outer material to form a foam layer 912 by foam molding. .

[0087] At the end of the extension panel body 9 facing the cover panel body 8, that is, the lower end of the extension panel body 9, a metal square is embedded as a reinforcing material 26 in the foam layer 912. In addition, at the end of the extension panel body 9 facing the cover panel body 8, the exterior material 911 is formed with a plurality of holding wall portions 914 for holding the reinforcing material 26 in parallel to the side walls. Yes.

[0088] The wall portion 914 for retaining the reinforcing material prevents the displacement of the reinforcing material 26 when the foaming raw material is injected and foam-molded, and the reinforcing material 26 is finally formed in the foam layer 912. It is fixed by and integrated into the panel. As a result, warpage and stagnation of the extension panel body 9 are suppressed.

In this embodiment, the wall portion 914 is not limited to the force S mainly used for preventing the displacement of the reinforcing material, but may be a locking means for locking the reinforcing material 26. it can . In this case, regardless of the foam layer 912, the reinforcing material 26 can be fixed to suppress warping and stagnation of the extension panel 9.
