[0006] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. CONTENT OF THE UTILITY MODEL

[0007] In order to have a basic understanding of some aspects of the disclosed embodiments, the following is a simple summary. The summary is not a general review, nor is it intended to determine the key / important constituent elements or delineate the scope of protection of these embodiments, but as a prelude to the detailed description below.

[0008] The panel assembly for an indoor unit of an air conditioner and the indoor unit of an air conditioner provided by the embodiments of the present disclosure can prevent the formation of a turbulent flow between the return air flow and the outlet air flow, and reduce the risk of condensation of the panel assembly.

[0010] Optionally, the air outlet frames and the air inlet frames are arranged adjacent to each other along the length direction of the panel body, and the air outlets and the air inlets are arranged along the length direction of the panel body; wherein the first side is one side of the panel body along the width direction, and the second side is the other side of the panel body along the width direction.

[0011] Optionally, the bars of the grille comprise first ends of the bars close to the air outlet, and the first ends of the bars are provided with air guiding portions for guiding the air flow at the first ends of the bars to flow towards the middle part of the air inlet.

[0012] Optionally, the air guiding portion comprises: an air guiding surface, extending along the first end of the bar towards the middle part of the bar, and the air guiding surface is inclined towards the air inlet along the direction from the first end of the bar towards the middle part of the bar.

[0013] Optionally, the inclination angle of the air deflector towards the first side ranges from 0° to 70°; and / or, the inclination angle of the bars of the grille towards the second side ranges from 30° to 60°.

[0014] Optionally, the aspect ratio of the air inlet frame is the same as the aspect ratio of the air outlet frame.

[0015] Optionally, the aspect ratio of the air inlet frame and the aspect ratio of the air outlet frame both range from 3:1 to 5:1.

[0016] Optionally, the number of the air inlet frames is multiple, and the multiple air inlet frames comprise: a first air inlet frame, arranged at one side of the air outlet frame along the length direction of the panel body; and a second air inlet frame, arranged at the other side of the air outlet frame along the length direction of the panel body.

[0017] According to the second aspect of the embodiment of the present application, an indoor unit of an air conditioner is provided, comprising the panel assembly for the indoor unit of the air conditioner as disclosed in any one of the above embodiments.

[0019] The panel assembly and indoor unit of an air conditioner provided in this disclosure can achieve the following technical effects:

[0020] The first and second sides are positioned opposite each other, allowing the outlet and return airflows to flow on opposite sides of the panel. This ensures that the airflow paths for the outlet and return air are independent, reducing interference between them. The outlet airflow is smoothly directed towards the first side, while the return airflow is stably drawn into the inlet from the second side. This effectively avoids the turbulent flow of hot and cold air caused by adjacent inlets and outlets, thus reducing the risk of condensation in the panel area between the inlets and outlets and at the outlets. Furthermore, the absence of mutual cancellation or turbulence between the return and outlet airflows improves the air conditioning's output and return air efficiency. In addition, the adjacent placement of the outlet and inlet frames integrates the outlet and return air functions onto the same plane of the panel, improving space utilization and resulting in a simpler and more aesthetically pleasing overall design.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0046] Combination Figures 1-8 As shown, this disclosure provides a panel assembly for an indoor unit of an air conditioner, including a panel body 10, an air guide plate 40, and a grille 50.

[0047] The panel body 10 includes an adjacent air outlet frame 20 and an air inlet frame 30. The air outlet frame 20 is provided with an air outlet 21, and the air inlet frame 30 is provided with an air inlet 31. The panel body 10 also includes a first side 11 and a second side 12 opposite to each other. A guide plate 40 is provided at the air outlet 21, and the guide plate 40 can tilt toward the first side 11 to open the air outlet 21 so that the air outlet 21 discharges air along the first side 11. A grille 50 is provided at the air inlet 31, and the grille bars 51 of the grille 50 are tilted toward the second side 12 so that the air inlet 31 returns air from the second side 12.

[0048] The first side 11 and the second side 12 are positioned opposite each other, allowing the outlet airflow and return airflow to flow on opposite sides of the panel. The outlet airflow flows from the outlet towards the first side 11. The return airflow flows from the second side 12 towards the inlet. The outlet direction is as follows: Figure 1 and Figure 3 As indicated by the middle arrow o, the return air direction is as follows: Figure 1 and Figure 3 The direction indicated by the middle arrow i.

[0049] If the first side 11 is the left side, then the second side 12 is the right side. If the first side 11 is the front side, then the second side 12 is the rear side. For example, in the width direction of the panel body 10 (e.g. Figure 5 Using the direction of the middle arrow as a reference, the first side 11 is the left side of the panel center, and the second side 12 is the right side of the panel center. The air guide plate is inclined towards the first side 11, meaning the air guide plate opens the air outlet towards the left side of the panel body along the width direction, and the airflow flows out of the air outlet from the left side of the panel body along the width direction. The grille 50's bars 51 are inclined towards the second side 12, and the return airflow enters the air inlet 31 from the second side 12, meaning the grille 51 opens the air inlet towards the right side of the panel body along the width direction, and the return airflow enters the air inlet from the right side of the panel body 10 along the width direction. This effectively avoids mutual interference between the return airflow and the outlet airflow, thereby reducing the turbulence phenomenon formed between the cold airflow and the warm airflow.

[0050] The panel assembly for an indoor unit of an air conditioner provided in this embodiment is arranged with the first side 11 and the second side 12 facing each other, allowing the outlet airflow and return airflow to flow on opposite sides of the panel respectively. This makes the airflow paths of the outlet and return air independent, reducing interference between them. The outlet airflow can smoothly exit through the outlet 21 towards the first side 11, while the return airflow is stably drawn into the inlet 31 from the second side 12. This effectively avoids the turbulence of hot and cold air caused by the adjacent arrangement of the inlet 31 and the outlet 21, thereby reducing the risk of condensation in the panel body 10 area between the inlet 31 and the outlet 21, as well as at the outlet 21. Simultaneously, the return airflow and outlet airflow no longer cancel each other out or become turbulent, improving the air conditioning's outlet efficiency and return air effect. Furthermore, the outlet frame 20 and the inlet frame 30 are arranged adjacently, integrating the outlet and return air functions on the same plane of the panel body 10, improving space utilization efficiency and making the overall design of the panel body 10 simpler and more aesthetically pleasing.

[0051] Optionally, combined Figure 5 As shown, the size of the air guide plate 40 is adapted to the size of the air outlet 21, and the size of the air guide plate 40 is less than or equal to the size of the air outlet frame 20; the size of the grille 50 is adapted to the size of the air inlet 31, and the size of the grille 50 is less than or equal to the size of the air inlet frame 30.

[0052] The size of the air guide plate 40 is matched with that of the air outlet 21, allowing the air guide plate 40 to completely cover the air outlet 21 and ensuring that the airflow is evenly distributed through the air guide plate 40. Simultaneously, the size of the air guide plate 40 is smaller than or equal to the size of the air outlet frame 20, ensuring that the air guide plate 40 does not exceed the range of the air outlet frame 20, resulting in a simpler overall structure for the panel assembly. Similarly, the size of the grille 50 is matched with that of the air inlet 31, allowing the grille 50 to completely cover the air inlet 31 and ensuring that the return airflow is evenly distributed through the grille 50. Simultaneously, the size of the grille 50 is smaller than or equal to that of the air inlet frame 30, ensuring that the grille 50 does not exceed the range of the air inlet frame 30, resulting in a simpler overall structure for the panel assembly.

[0053] Optionally, combined Figure 5 and Figure 8 As shown, the grille 50 includes a plurality of grille bars 51, all of which are inclined toward the second side.

[0054] The multiple bars 51 of the grille 50 are all inclined towards the second side, which can effectively guide the return airflow from the second side into the air inlet 31. This inclined design allows the airflow to pass through the grille 50 more smoothly, reducing the resistance of the return airflow and improving the efficiency and stability of the return airflow.

[0055] Optionally, combined Figure 1 , Figure 2 andFigures 4-5 As shown, the air outlet frame 20 and the air inlet frame 30 are arranged adjacent to each other along the length direction of the panel body 10, and the air outlet 21 and the air inlet 31 are arranged along the length direction of the panel body 10; wherein, the first side is one side of the panel body 10 along the width direction, and the second side is the other side of the panel body 10 along the width direction.

[0056] The air outlet frame 20 and the air inlet frame 30 are located on the same plane of the panel body 10, which facilitates the installation and disassembly of the panel body 10, saves installation space, and reduces the occupancy of indoor space. The length direction of the panel body 10 is as follows: Figure 2 As indicated by the middle arrow, the air outlet frame 20 and air inlet frame 30 are arranged adjacent to each other along the length of the panel, and the air outlet 21 and air inlet 31 are arranged along the length of the panel, making the overall structure of the panel body 10 more compact and elongated. This improves the visual effect of the panel assembly, making it more aesthetically pleasing and concise. Furthermore, compared to the traditional ducted air conditioner's bottom return and side air outlet configuration, this design makes more rational use of the space in the panel body 10, enhancing the overall installation flexibility and spatial adaptability of the panel assembly.

[0057] The width direction of the panel body 10 is as follows Figure 5 As indicated by the arrow, the first side 11 and the second side 12 of the panel body 10 are two sides arranged opposite each other along the width direction of the panel body 10, allowing the air conditioner to draw in and expel air along the width direction of the panel body 10. The air guide plate 40 can tilt towards the first side to open the air outlet 21, allowing the air outlet 21 to discharge air towards the first side along the width direction of the panel body 10. The grille 50's bars 51 are tilted towards the second side, allowing the air inlet 31 to return air from the second side along the width direction of the panel body 10. At this time, the air inlet 31 and the air outlet 21 extend along the length direction of the panel body 10, returning or discharging air along the width direction of the panel body 10, which can increase the air outlet area and thus improve the return and discharge efficiency. It can be understood that the first side and the second side can also be two sides arranged opposite each other along the length direction of the panel body 10.

[0058] When the air conditioner is a ducted unit, it is typically installed in the indoor ceiling. In this case, the first side 11 of the panel body 10 along the width direction can be the front side, and the second side 12 of the panel body along the width direction can be the rear side. The exhaust air flows out of the air outlet 21 towards the front side, achieving cooling or heating of the indoor space. The return air enters the air inlet 31 from the rear side.

[0059] Optionally, combined Figures 5-7 As shown, the grille 50 has a first end 511 near the air outlet 21. The first end 511 of the grille is provided with an air guide 513 for guiding the return airflow at the first end 311 of the air inlet toward the center 312 of the air inlet.

[0060] The first end 511 of the grille corresponds to the first end 311 of the air inlet, and the first end 511 of the grille is located at the first end 311 of the air inlet. The first end 511 of the grille and the first end 311 of the air inlet are close to the air outlet 21. The first end 511 of the grille is provided with a guide section 513, which can effectively guide the return airflow at the first end 311 of the air inlet toward the center 312 of the air inlet. This can more effectively separate the return airflow and the outlet airflow, avoid the return airflow and outlet airflow from interfering with each other and causing turbulence, thereby effectively avoiding condensation.

[0061] It is understandable that the second end of the grille 51, which is away from the air outlet 21, can also be provided with an air guide 513.

[0062] By providing air guides 513 at both the first end 511 and the second end of the grille 51, the return airflow is made to flow evenly from both ends of the air inlet 31 to the middle. This not only improves the return air efficiency but also reduces airflow resistance.

[0063] Optionally, combined Figure 6 and Figure 7 As shown, the air guide section 513 includes an air guide surface 514, which extends from the first end 511 of the grid bar toward the middle part 512 of the grid bar, and the air guide surface 514 is inclined toward the air inlet 31 in the direction from the first end 511 of the grid bar toward the middle part 512 of the grid bar.

[0064] The direction of the first end 511 of the grid bar toward the middle part 512 of the grid bar is as follows Figure 7 As indicated by the middle arrow. The air guide 513, in the form of an air guide surface 514, guides the return airflow toward the center of the air inlet 312, causing the return airflow to concentrate toward the center of the air inlet 312. The grille 50 is located at the air inlet 31, guiding the air to flow toward the interior of the air inlet 31, forming a return airflow. The air guide surface 514 extends from the first end 511 of the grille towards the center of the grille 512, guiding the return airflow at the first end 311 of the air inlet toward the center of the air inlet 312, thus moving the return airflow away from the air outlet 21. The air guide surface 514 is inclined toward the air inlet 31 in the direction from the first end 511 of the grille toward the center of the grille 512. The inclined arrangement of the air guide surface 514 can guide the return airflow toward the interior of the air inlet 31, thereby enhancing the guiding effect of the air guide surface 514.

[0065] When air enters the air inlet 31, the inclined guide surface 514 can more smoothly guide the return airflow at the first end 511 of the grille into the middle 312 of the air inlet, effectively reducing the wind field of the return airflow at the first end 511 of the grille. This can increase the distance between the return airflow and the outlet airflow, reduce the interference between the return airflow and the outlet airflow, and thus effectively avoid condensation caused by the mixing of warm and cold airflows.

[0066] Optionally, combined Figures 1-3 , Figure 5 and Figure 6 As shown, the tilt angle of the air guide plate 40 toward the first side ranges from 0° to 70°.

[0067] The tilt angle of the air guide plate 40 toward the first side is as follows: Figure 3 The angle α represents the opening angle of the air guide plate 40 relative to the plane of the panel body 10. The air guide plate 40 can move relative to the air outlet 21 to open or close the air outlet 21. The tilt angle of the air guide plate 40 toward the first side can be adjusted between 0° and 70°, thereby adjusting the opening area of ​​the air outlet 21.

[0068] When the tilt angle of the air guide plate 40 toward the first side is equal to 0°, combined with Figure 5 and Figure 6 As shown, the air guide plate 40 is in the closed state. At this time, the air guide plate 40 completely closes the air outlet 21, which can prevent dust and impurities from entering the interior of the indoor unit of the air conditioner.

[0069] When the tilt angle of the air guide plate 40 toward the first side is greater than 0°, combined with Figures 1-3 As shown, the air guide plate 40 is in the open state. At this time, the air guide plate 40 opens the air outlet 21, which can guide the airflow to be sent out towards the first side.

[0070] When the tilt angle of the air guide plate 40 towards the first side is less than or equal to 70°, it can effectively guide the airflow towards the first side, avoiding interference between the outlet airflow and the return airflow on the second side. This reduces turbulence caused by airflow interference, thereby preventing condensation caused by airflow mixing, and also improving airflow efficiency and comfort.

[0071] The present embodiment limits the tilt angle of the air guide plate 40 toward the first side to a range of 0° to 70°. The tilt angle of the air guide plate 40 can be adjusted between 0° and 70° according to different usage requirements. This allows the air conditioner to flexibly adjust the air outlet direction while effectively separating the outlet airflow and return airflow, avoiding turbulence and condensation caused by airflow interference.

[0072] It is understandable that the tilt angle of the air guide plate 40 toward the first side can be 0°, 10°, 20°, 30°, 40°, 50°, 60°, or 70°.

[0073] Optionally, the air guide plate 40 is tilted at an angle of 70° toward the first side.

[0074] The 4070° tilt angle of the air guide plate allows the outlet airflow to be directed obliquely along the first side, avoiding interference with the return airflow on the second side. This reduces turbulence caused by airflow mixing and optimizes airflow guidance. Furthermore, without interference between the outlet and return airflows, the air guide plate 40 can open the outlet 21 at its maximum tilt angle, maximizing the area of ​​the outlet 21 and achieving maximum airflow efficiency. This allows the air conditioner to deliver airflow more efficiently, covering a wider indoor space and improving airflow efficiency.

[0075] Optionally, combined Figure 8 As shown, the angle of inclination of the bars 51 of the grille 50 toward the second side ranges from 30° to 60°.

[0076] The angle of inclination of the grille bars 51 toward the second side of the grille 50 is as follows: Figure 8 The angle β refers to the inclination angle of the grid bars 51 of the grille 50 relative to the plane of the panel body 10. The inclination angle of the grid bars 51 of the grille 50 is fixed, and the inclination angle of the grid bars 51 toward the second side can be set to any angle between 30° and 60°.

[0077] When the angle of inclination of the grille bars 51 of the grille 50 toward the second side is greater than or equal to 30°, the air inlet 31 can open a sufficient return air area, thereby effectively guiding the return airflow into the air inlet 31. This can avoid problems such as poor return airflow caused by the air inlet 31 opening area being too small.

[0078] When the angle of inclination of the grille bars 51 of the grille 50 toward the second side is less than or equal to 60°, it can effectively guide the return airflow to be inclined along the second side into the air inlet 31, avoiding interference between the return airflow and the outlet airflow on the first side. This can reduce turbulence caused by airflow interference, thereby avoiding condensation caused by airflow mixing, and also improving return air efficiency.

[0079] This embodiment of the disclosure limits the tilt angle of the grille bars 51 toward the second side to 30° to 60°, which can reduce turbulence caused by airflow interference, thereby avoiding condensation caused by airflow mixing, and also improving return air efficiency. It is understood that the grille bars 51 of the grille 50 can also be configured as an adjustable structure, capable of rotating relative to the air inlet frame 30 to adjust the opening angle of the air inlet 31.

[0080] It is understood that the tilt angle of the grille bars 51 of the grille 50 toward the second side can be 30°, 35°, 40°, 45°, 50°, 55°, or 60°.

[0081] Optionally, the slats 51 of the grille 50 are tilted at an angle of 45° toward the second side.

[0082] The grille bars 51 of the grille 50 form a fixed 45° angle relative to the plane of the panel body 10 facing the second side, optimizing return air efficiency and reducing airflow interference. This 45° angle not only allows the air inlet 31 to open sufficiently to prevent obstructed return airflow, but also effectively guides the return airflow into the air inlet 31 along the second side, preventing interference between the return airflow and the outlet airflow on the first side. This reduces turbulence caused by airflow mixing, prevents condensation, and improves return air efficiency.

[0083] Optionally, the aspect ratio of the air inlet frame 30 is the same as that of the air outlet frame 20.

[0084] The air inlet frame 30 and the air outlet frame 20 are arranged adjacent to each other, and the length-to-width ratio of the air inlet frame 30 and the air outlet frame 20 are the same. This makes the overall appearance of the panel body 10 uniformly linearly distributed, presenting a narrow and long visual effect. This improves the aesthetics of the panel assembly. The same length-to-width ratio gives the air inlet frame 30 and the air outlet frame 20 better structural symmetry and coordination, and also enhances the structural stability of the panel assembly. In addition, during the manufacturing process, the same length-to-width ratio facilitates unified mold design and production, which can improve production efficiency and reduce production costs.

[0085] Optionally, the aspect ratio of the air inlet frame 30 and the aspect ratio of the air outlet frame 20 are both in the range of 3:1 to 5:1.

[0086] The length-to-width ratio of the air inlet frame 30 is the same as that of the air outlet frame 20, both set to 3:1 to 5:1.

[0087] When the aspect ratio of the air inlet frame 30 to the air outlet frame 20 is greater than or equal to 3:1, the main panel 10 can achieve an extremely narrow visual effect, avoiding the bulkiness caused by an excessively wide frame. This also reduces installation space and enhances the product's aesthetics and spatial adaptability.

[0088] When the length-to-width ratio of the air inlet frame 30 and the length-to-width ratio of the air outlet frame 20 are less than or equal to 5:1, the air inlet frame 30 and the air outlet frame 20 have sufficient width to install the grille 50, the air guide plate 40 and the electronic control components 60, thus realizing the basic functions and structural stability of the panel body 10.

[0089] This embodiment limits the aspect ratio of the air inlet frame 30 and the air outlet frame 20 to a range of 3:1 to 5:1. This allows the panel body 10 to achieve an extremely narrow visual effect while still fulfilling the basic functions of the air inlet frame 30 and the air outlet frame 20, enabling the grille 50, air guide plate 40, and electronic control components 60 to be properly installed on the air inlet frame 30 or the air outlet frame 20. This balances the aesthetics and functionality of the panel body 10.

[0090] It is understandable that the aspect ratio of the air intake frame 30 and the aspect ratio of the air outlet frame 20 can be 3:1, 3.5:1, 4:1, 4.5:1, or 5:1.

[0091] Optionally, the aspect ratio of the air inlet frame 30 and the aspect ratio of the air outlet frame 20 are both 4:1.

[0092] This design ensures that the overall appearance of the panel body 10 is uniformly linearly distributed, achieving not only an extremely narrow visual effect but also guaranteeing the proper installation of the grille 50, air guide plate 40, and electronic control components 60, thus balancing aesthetics and functionality. Furthermore, the unified aspect ratio of the air inlet frame 30 and air outlet frame 20 optimizes the manufacturing cost of the panel body 10 and improves production efficiency.

[0093] Optionally, combined Figure 6 and Figure 7 As shown, the panel assembly also includes a filter 52, which is located at the air inlet 31.

[0094] A filter 52 is installed at the air inlet 31 to effectively filter the return airflow and prevent impurities from entering the air conditioning system.

[0095] Optionally, combined Figure 1 , Figure 2 and Figures 4-6 As shown, there are multiple air inlet frames 30, including a first air inlet frame 32 and a second air inlet frame 33. The first air inlet frame 32 is located on one side of the air outlet frame 20 along the length direction of the panel body 10; the second air inlet frame 33 is located on the other side of the air outlet frame 20 along the length direction of the panel body 10.

[0096] The first air inlet frame 32 is disposed on one side of the air outlet frame 20 along the length direction of the panel body 10, and the second air inlet frame 33 is disposed on the other side of the air outlet frame 20 along the length direction of the panel body 10. The first air inlet frame 32, the air outlet frame 20, and the second air inlet frame 33 are arranged sequentially along the length direction of the panel body 10. Correspondingly, there are multiple air inlets 31, including a first air inlet 321 and a second air inlet 331. The first air inlet 321 is disposed on the first air inlet frame 32, and the second air inlet 331 is disposed on the second air inlet frame 33.

[0097] The arrangement of multiple air inlet frames 30 increases the total return air area and improves the return air volume of the air conditioner, thereby enhancing the efficiency of cooling or heating. The first air inlet frame 32 and the second air inlet frame 33 are located on both sides of the air outlet frame 20, and the first air inlet 321 and the second air inlet 331 are located on both sides of the air outlet 21. This symmetrical layout makes the return air more uniform and avoids the airflow imbalance caused by unilateral return air.

[0098] Accordingly, combined Figure 5 As shown, there are multiple grilles 50, including a first grille 53 and a second grille 54. The first grille 53 is located on the first air inlet frame 32 and at the first air inlet 321; the second grille 54 is located on the second air inlet frame 33 and at the second air inlet 331. The bars 51 of the first grille 53 and the bars 51 of the second grille 54 are both inclined towards the second side to achieve the effect of air return from the second side.

[0099] With the same aspect ratio of the air inlet frame 30 and the air outlet frame 20, the aspect ratios of the first air inlet frame 32, the air outlet frame 20, and the second air inlet frame 33 are also the same. By making the overall layout of the panel body 10 compact and adjusting the overall aspect ratio of the control panel body 10, the appearance of the panel body 10 is made to be more uniform and linearly distributed.

[0100] Optionally, the aspect ratio of the first air inlet frame 32, the air outlet frame 20, and the second air inlet frame 33 is 4:1.

[0101] This design effectively enhances the visual effect of the ultra-narrow panel body 10, resulting in a simpler overall structure. It also saves installation space and facilitates after-sales installation.

[0102] It is understandable that the first air intake frame 32, the air outlet frame 20, and the second air intake frame 33 can be a one-piece design or a detachable connection.

[0103] This disclosure provides an indoor unit for an air conditioner, including a panel assembly for the indoor unit as described in any of the above-disclosed embodiments.

[0104] The air conditioner indoor unit provided in this embodiment includes the panel assembly for the air conditioner indoor unit as described in any of the above-described embodiments, and therefore has all the beneficial effects of the panel assembly for the air conditioner indoor unit as described in any of the above-described embodiments, which will not be repeated here.

[0105] Optionally, combined Figure 2 As shown, the indoor unit of the air conditioner also includes an electronic control component 60, which is located on the air inlet frame 30 and / or the air outlet frame 20. The electronic control component 60 includes multiple electronic control modules 61, which are arranged along the length of the panel body 10.

[0106] The indoor unit of the air conditioner also includes an electronic control component 60, which can be located on the air inlet frame 30 or the air outlet frame 20. The electronic control component 60 includes multiple electronic control modules 61, which are arranged along the length of the panel body 10, resulting in a compact layout. With the air outlet frame 20 and the air inlet frame 30 arranged adjacent to each other along the length of the panel body 10, this arrangement of multiple electronic control modules 61 along the length of the panel body 10 better accommodates the extremely narrow structure of the panel body 10.
