[0031] The fixing member 2 comprises a fixing part 21 and a plurality of bending parts 22, one side of the fixing part 21 is connected to the panel 1, and the other side is connected to the plurality of bending parts 22;
[0032] The lower middle part of the bending part 22 is provided with a hollow area 221, and the two sides of the hollow area 221 are the connecting arms 222 of the bending part 22, which are connected to the fixing part 21, and the adjacent bending parts 22 connected to the same fixing part 21 are not connected, the bending part 22 can be bent towards the panel 1 relative to the fixing part 21, and the plurality of bending parts 22 after bending are opposite to the panel 1 and fix the thermal insulation cotton 4 together; the top of the bending part 22 is provided with an everted edge 223, and the bending direction of the everted edge 223 is away from one side of the panel 1;
[0033] The panel 1, the side edges 3 and the fixing members 2 are made of sheet metal material, and the panel 1, the side edges 3 and the fixing members 2 are integrated.
[0034] The existing air conditioner shell generally pastes the same size thermal insulation cotton, further ensures that the performance of the air conditioner meets the standard, effectively reduces the heat exchange between the inside of the air conditioner and the outside world, improves the refrigeration or heating effect, and meets the safety requirements. The thermal insulation cotton used is glass wool, but the glass wool fiber is loose and easy to fall off. In order to reduce the fiber from falling off and flying out from the four edges, the existing technology generally uses aluminum foil edge covering or fixed bending to fix the glass wool, but the aluminum foil edge covering will increase the used materials and increase the cost, and the like Figure 5As shown, the fixed bending is provided, the existing fixed bending is 90°, when installing, the glass wool is not easy to be inserted into the fixed bending, and in the process of inserting, the glass wool is abraded, so that the edge of the glass wool is more easy to fly out. For this purpose, the utility model provides a kind of edge pressing structure for thermal insulation cotton, including panel 1 and several fixed parts 2, several fixed parts 2 are located in the same face of panel 1, glue is sprayed on the face of panel 1, so that glass wool with the size of panel 1 is attached to panel 1, fixed part 21 and several bending parts 22 are included in fixed part 2, bending part 22 can be bent to panel 1 relative to fixed part 21, i.e. after glass wool is attached to panel 1, bending part 22 is bent to panel 1, so that glass wool is fixed, at the same time, fixed part 2 is arranged at the edge of panel 1, and the length of the bottom of fixed part 2 is equal to the length of the edge of panel 1, the edge of glass wool is completely blocked by fixed part 21, in addition, the length of side edge 3 is equal to the length of the connected edge, and the edge of glass wool is attached with fixed part 21, to solve the problem that fiber of fixed glass wool of air conditioner shell is easy to fall off and fly out from all around.
[0035] At the same time, the panel 1 and the fixed part 2 are integrated structure, the integrated structure is beneficial to overall production, without increasing other materials such as aluminum foil, increasing cost. The panel 1, the side edge 3 and the fixed part 2 are sheet metal material, the sheet metal has certain toughness, when installing and fixing glass wool, the connecting arm 222 and the fixed part 21 are not easy to break when manually bending the bending part 22, and the lower middle of the bending part 22 is provided with a hollow area 221, the two sides of the hollow area 221 are the connecting arms 222 of the bending part 22, the connecting arms 222 are connected to the fixed part 21, the setting of the hollow area 221 ensures that the connection length between the bending part 22 and the fixed part 21 is short, the force required by the short connection length is small, and the several bending parts 22 connected to the same fixed part 21 are not connected, which effectively ensures the rigidity of the bending part 22, so that the labor intensity of installation personnel is effectively reduced in the process of manual bending and frequent bending operation, and the strength of the edge pressing structure is ensured, which is beneficial to large-scale production, reduces labor time, reduces cost, and does not need to insert glass wool into fixed structure, effectively prevents damage to glass wool in the process of installation, and solves the problem of difficult installation of thermal insulation cotton.
[0036] In addition, the top of the bending part 22 is provided with an outward flange 223, which is away from the panel 1, preventing the damage of the insulation cotton 4 installed on the panel 1. The outward flange 223 can increase the rigidity of the bending part 22. Without the outward flange 223, the metal strength of the bending part 22 will be weakened, and it is not easy to compress the edge of the insulation cotton. Therefore, the outward flange 223 makes the bending part 22 more stable when bearing the force of the installer, and is not easy to deform. In addition, the outward flange 223 can disperse the stress on the bending part 22 to a wider area, reduce stress concentration, and improve the strength and durability of the entire structure. In addition, the outward flange 223 is beneficial to the quick positioning of the bending part 22 by the installer during installation, and the connecting arm 222 ensures that the bending part 22 is quickly bent to the required position.
[0037] Preferably, the distance X between the connecting arms 222 of the same bending part 22 is 100-200 mm, and the width W of the connecting arm 222 is 5-15 mm.
[0038] Specifically, the length of the hollow area 221 is limited to ensure that the bending part 22 has corresponding strength. If the distance X between the connecting arms 222 of the bending part 22 is too large, the connecting arm 222 needs to support a larger volume of the bending part 22, resulting in stress concentration and reduced strength, and after bending, the glass wool cannot be effectively fixed. If the distance X between the connecting arms 222 of the bending part 22 is too small, too many bending parts 22 are provided on the same fixing part 21, and multiple bending parts 22 need to be bent during the installation of the glass wool, increasing the production time and process difficulty.
[0039] At the same time, the width W of the connecting arm 222 is 5-15 mm, which, based on the material of the metal, ensures that the outer layer of the connecting arm 222 is subjected to tensile stress and the inner layer is subjected to compressive stress during installation, increasing the possibility of deformation of the connecting arm 222, making it easy to process the bending part 22, facilitating the bending of the bending part 22, and achieving the installation of the glass wool. The distance limit between the connecting arms 222 of the bending part 22 is adapted to ensure the strength of the bending part 22 while facilitating installation and processing.
[0040] Preferably, the thickness of the panel 1, the side 3 and the fixing part 2 is equal, and the thickness is 1-1.5 mm.
[0041] Specifically, the thickness of the panel 1, the side edge 3 and the fixing member 2 is equal, the strength distribution of the whole structure is uniform, there is no weak link caused by thickness difference, the material selection in the production process can be simplified, the waste caused by splicing and combination of different thickness sheet metals is reduced, and the sheet metal has a certain toughness. When the thickness of the sheet metal is 1-1.5 mm, the sheet metal has sufficient strength and toughness during the bending process of the connecting arm 222, is not easy to break or crack, and is thin enough to facilitate processing and operation.
[0042] In addition, the sheet metal in this thickness range produces less waste during processing, has relatively high material utilization, can effectively reduce the use amount and production cost under the premise of meeting the required strength of the air conditioner shell, and the processing difficulty of the sheet metal of this thickness is relatively low. In the process of being processed into the required shape, it is not easy to deform and damage, reduces the rework and scrap rate caused by quality problems, and further improves production efficiency and economic benefits.
[0043] Preferably, the fixing member 2 is isosceles trapezoidal.
[0044] Specifically, the fixing member 2 is isosceles trapezoidal, and the fixing member 2 includes a fixing part 21 and a plurality of bending parts 22. Because it has a corresponding hypotenuse, that is, the waist of the isosceles trapezoid, when several sheet metals are assembled and spliced, the bending parts 22 of adjacent sheet metals will not interfere with each other, and during installation, the installer can bend the bending parts 22 more easily, without interference with the side edge 3 or other bending parts 22, improving installation efficiency and reducing installation errors or the need for re-adjustment caused by interference.
[0045] Preferably, the height h1 of the fixing part 21 is equal to 70-100% of the thickness of the thermal insulation cotton 4.
[0046] Specifically, after the bending part 22 is subjected to an acting force, the edge of the thermal insulation cotton 4 is attached to the fixing part 21, and the height of the fixing part 21 is equal to 70-100% of the height of the thermal insulation cotton 4. It can effectively press the edge and ensure that the edge of the thermal insulation cotton 4 is fixed and effectively attached to the fixing part 21, so that the thermal insulation cotton 4 is not easy to displace or slide during use, and the situation that the face is not easy to compress due to excessive compression of the thermal insulation cotton 4 can be avoided.
[0047] Preferably, the height h2 of the bending part 22 is 10-30 mm.
[0048] Specifically, the height of the bending part 22 is 10-30 mm. After the thermal insulation cotton 4 is compressed, the contact surface of the bending part 22 with the thermal insulation cotton 4 will be subjected to an outward force, and the acting force will be transmitted to the bending part 22. In the case where the width of the hollow area 221 and the connecting arm 222 is constant, the stress receiving surface is small, which can reduce stress concentration and make the stress more evenly distributed in the bending part 22, effectively avoiding material deformation or damage caused by excessive local stress, and improving the stability and durability of the entire structure. Therefore, in order to ensure a more convenient bending process and effectively cover the deviation for edge compression, the height of the bending part 22 is limited to 10-30 mm, which improves the stability and durability of the entire structure while ensuring effective edge compression.
[0049] Preferably, the top of the side edge 3 is folded away from one side of the panel 1, and the middle part of the side edge 3 is provided with a plurality of through holes 31.
[0050] Specifically, the side edge 3 and the fixed part 21 together block the periphery of the thermal insulation cotton 4. The top of the side edge 3 is folded away from one side of the panel 1. After folding, the top of the side edge 3 forms an additional support structure, effectively providing the strength of the entire structure.
[0051] In addition, the middle part of the side edge 3 is provided with a plurality of through holes 31. The arrangement of the plurality of through holes 31 reduces the material cross-sectional area of the middle part of the side edge 3 to some extent, so that the required force is reduced during the bending process, thereby facilitating the bending of the side edge 3 along the middle part to one side of the panel 1. During installation, the side edge 3 is bent together with the bending part 22, thereby clamping multiple edges of the thermal insulation cotton 4, more effectively preventing the fibers of the thermal insulation cotton 4 from flying out, and facilitating installation. At the same time, the through holes 31 help to reduce the weight of the entire structure, facilitating subsequent assembly of the entire air conditioner.
[0052] Preferably, the fixed part 21 is provided with a limiting piece 211 at the joint with the hollow area 221. The limiting piece 211 is an integrated structure with the panel 1, and the limiting piece 211 is not larger than the hollow area 221.
[0053] Specifically, the arrangement of the limiting piece 211 effectively improves the strength of the entire structure to some extent.
[0054] At the same time, the limiting piece 211 is not larger than the hollow area 221. During processing, the fixed part 2 is processed. When the fixed part 2 is a whole plate at the beginning, the hollow area 221 is partially cut to obtain the required hollow area 221 and limiting piece 211, thereby reducing the processing difficulty and reducing waste materials.
[0055] Further, the limiting piece 211 is located away from one side of the panel 1, and the included angle between the limiting piece 211 and the fixed part 21 is 90°.
[0056] The included angle between the limiting piece 211 and the fixed part 21 is 90°, after the installation of the heat preservation cotton 4, the subsequent installation of the device required by the air conditioner is needed, and the air pipe at the top of the air conditioner is one of the indispensable components, the included angle between the limiting piece 211 and the fixed part 21 is 90°, that is, the limiting piece 211 and the fixed part 21 are jointly attached to the air pipe sheet metal required for installing the air pipe, the limiting piece 211 can reduce the processing difficulty and reduce the waste material, and can position and fix the air pipe required for installing the air conditioner at the top, improve the convenience.
[0057] Preferably, the shape of the hollow area 221 is rectangular.
[0058] The regular shape of the rectangle helps to uniformly distribute stress during bending, and compared with a circular or irregular shape, the edges of the rectangle are relatively smooth and have no sharp corners, reducing the formation of stress concentration points, thereby reducing the risk of fracture or deformation of the bent part 22 at the connecting arm 222.
[0059] In addition, the shape of the rectangle is relatively simple, and the limiting piece 211 can be easily processed by stamping, cutting and other processes, improving production efficiency and reducing processing cost.
[0060] The technical principle of the utility model is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the utility model, and cannot be interpreted as limiting the protection scope of the utility model in any way. Based on the explanation here, those skilled in the art can think of other specific embodiments of the utility model without creative labor, and these embodiments will fall within the protection scope of the utility model.
