[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0056] like Figure 1-Figure 20 As shown, the present invention provides an air conditioning box 100, which is used to receive and protect the air conditioner to prevent the air conditioner from being damaged during use, resulting in a reduction in service life.

[0057] The air conditioning box 100 includes a frame 10 and an insulation panel 20, which is inserted into the frame 10; the frame 10 includes a frame profile 60, an intermediate profile 70 and an angle tee profile 50, and the frame profile 60, the intermediate profile 70 and the angle tee profile 50 are all provided with a connecting plate 12, and a second sealing plate 13 is laid on the connecting plate 12; the insulation panel 20 is sealed with the frame 10 by squeezing the second sealing plate 13.

[0058] like Figure 18-Figure 20 As shown, the corner tee profile 50 includes a body 51 and a third sealing plate 52. The body 51 has three adjacent and mutually perpendicular mounting surfaces 511. Each mounting surface 511 is provided with an extension arm 512 which is perpendicular to the corresponding mounting surface 511 and is used to connect the frame profile 60. The extension arm 512 extends into the frame profile 60 to connect the two to each other. The third sealing plate 52 is installed on the mounting surface 511, and the extension arm 512 extends into the frame profile 60 to squeeze the third sealing plate 52 to seal the mounting surface 511 and the corresponding frame profile 60. The gap is used to improve the sealing effect of the assembly of the corner tee profile 50 and the frame profile 60, to avoid air flowing inside, forming cross-wind leading to heat transfer, causing condensation in the box, and improving the service life of the air-conditioning box 100; and the corner tee profile 50 has a connecting piece 54, the connecting piece 54 is installed on the main body 51 and is located at the intersection of three adjacent mounting surfaces 511, the connecting plate 12 of the frame profile 60 abuts against the connecting piece 54 to form a groove 57, and the groove 57 is filled with sealant 23 to seal the corner tee profile 50 and the frame profile 60.

[0059] like Figure 5 , Fig.14 and Fig.15As shown, the connecting plate 12 of the intermediate profile 70 extends along the length direction of the intermediate profile 70 and is arranged on both sides of the intermediate profile 70. One end of the intermediate profile 70 has a lap joint portion that protrudes from the end of the connecting plate 12 of the intermediate profile 70. The lap joint portion is overlapped on the connecting plate 12 of the frame profile 60 and abuts against the second sealing plate 13 of the frame profile 60. The second sealing plate 13 is deformed under pressure to seal the intermediate profile 70 and the frame profile 60.

[0060] See also Figure 1-Figure 5 The air-conditioning box body 100 has an inner side 101 and an outer side 102 which are arranged relatively to each other, and includes a sealing cover assembly 30; a mounting hole 11 is provided on the side of the frame 10, and a connecting plate 12 is provided on the hole wall of each mounting hole 11 at one end close to the inner side 101 of the box body, and the insulation panel 20 is filled in the mounting hole 11 and abutted against the connecting plate 12 to achieve a sealed connection of the air-conditioning box body 100; a sealing cover assembly 30 is correspondingly provided on the side of the outer side 102 of each frame 10, and the sealing cover assembly 30 can cover the first gap 21 between the insulation panel 20 and the frame 10 on the side of the corresponding frame 10; thereby, the sealed connection of the air-conditioning box body 100 is achieved from the sealing of the inner and outer sides, effectively reducing the heat loss of the air-conditioning box body 100 structure, and preventing condensation of the air-conditioning box body 100; at the same time, the sealing cover assembly 30 is sealedly connected to the insulation panel 20 and the frame 10 respectively, further improving the strength of the air-conditioning box body 100.

[0061] Furthermore, if Figure 3 and Figure 5 As shown, the sealing cover assembly 30 includes a plurality of corner cover plates 31 and a plurality of frame cover plate units 32. The plurality of frame cover plate units 32 form a ring and cover the first gap 21 between the insulation panel 20 and the frame 10, thereby improving the sealing strength of the air-conditioning box 100. Each corner cover plate 31 is arranged between two adjacent frame cover plate units 32, and the two adjacent frame cover plate units 32 are connected by the corner cover plate 31, thereby strengthening the connection strength between the frame 10 and the sealing cover assembly 30.

[0062] Specifically, Fig.11 and Fig.12 As shown, each frame cover unit 32 includes a frame cover 321 and a first sealing plate 322. The first sealing plate 322 is respectively mounted on the frame 10 and the insulation panel 20. The frame cover 321 covers the first sealing plate 322 and is respectively fixedly connected to the frame 10 and the insulation panel 20 to form a first seal. The first sealing plate 322 seals the first gap 21 between the insulation panel 20 and the frame 10, thereby improving the sealing of the box.

[0063] like Fig.13 and Fig.14As shown, the connecting plate 12 is covered with a second sealing plate 13, and the thermal insulation panel 20 is against the second sealing plate 13. The thermal insulation panel 20 squeezes the second sealing plate 13 to form a sealed connection with the second sealing plate 13. After the primary sealing of the first sealing plate 322, the second sealing plate 13 plays a secondary sealing role to strengthen the sealing of the gap between the thermal insulation panel 20 and the frame 10, thereby preventing air leakage of the air-conditioning box 100.

[0064] For further information, see Figure 11-Figure 14 A third gap 25 and a fourth gap 26 are formed between the first sealing plate 322 and the second sealing plate 13 on both sides of the thermal insulation panel 20, and the third gap 25 and the fourth gap 26 are filled with sealant 23; after the secondary sealing of the first sealing plate 322 and the second sealing plate 13, the third gap 25 on both sides of the thermal insulation panel 20 is filled with sealant 23 to achieve the third sealing, and the fourth gap 26 is filled with sealant 23 to achieve the fourth sealing effect, thereby strengthening the sealing of the air conditioning box 100 through four sealings, and improving the reliability of the air leakage prevention of the air conditioning box 100.

[0065] In the present application, the sealant 23 is a silicone-free sealant. Of course, in other embodiments, a sealant having the same sealing effect may also be used, such as a polyurethane sealant.

[0066] like Figure 5 and Fig.10 As shown, two adjacent insulation panels 20 are sealed and spliced ​​together via a snap-fit ​​structure 40 , and the snap-fit ​​structure 40 can achieve a stable connection between the adjacent insulation panels 20 .

[0067] Furthermore, the snap-on structure 40 includes a first snap-on 41 disposed on one side of one of the insulation panels 20, and a first slot 42 is opened on the other insulation panel 20. The first snap-on 41 is snapped into the first slot 42 to achieve the first stable sealing connection between the insulation panels 20.

[0068] Furthermore, a sealing tape 43 is provided in the first card slot 42. When the first clip 41 is connected to the first card slot 42 to achieve the first stable seal, when two adjacent insulation panels 20 are connected to each other through the sealing tape 43 provided in the first card slot 42, the first clip 41 is sealed against the first card slot 42 to achieve a second seal, thereby further improving the sealing between the insulation panels 20.

[0069] Specifically, a second gap 22 is formed between two adjacent insulation panels 20, and a sealant 23 is filled in the second gap 22, thereby achieving a third sealing between the two adjacent insulation panels 20. The sealing performance is enhanced by the three sealings to avoid air leakage of the air conditioning box 100.

[0070] See also Figure 6-Figure 7 The connecting plate 12 and the insulation panel 20 are locked by a screw 24, and one end of the screw 24 is buried in the insulation panel 20. In this way, the screw 24 is buried in the insulation panel 20 from the inner side 101 of the air conditioning box 100 to avoid forming a channel and generating cross-wind, so as to enhance the sealing of the air conditioning box 100.

[0071] Furthermore, the sealing cover plate assembly 30 is provided with a connection hole 33, the outer side 102 of the frame 10 is provided with a connection groove 103, a connection strip 1031 is installed in the connection groove 103, and the screw member 24 is sequentially passed through the connection hole 33 and the connection strip 1031 to tightly connect the sealing cover plate assembly 30 with the frame 10. The sealing cover plate assembly 30 and the frame 10 are fixed together from the outside of the air conditioning box 100 to enhance the connection strength, and the screw member 24 is deeply buried in the insulation panel 20 to avoid forming a channel and generating cross-wind; thus, the air conditioning box 100 is fixedly connected with the screw member 24 from the inside and outside of the air conditioning box 100 to further enhance the sealing of the air conditioning box 100.

[0072] like Figure 17-Figure 20 As shown, the air conditioning box 100 also includes a corner tee profile 50, which is an important component of the air conditioning box 100 and is usually arranged at the corners of the air conditioning box 100 for connecting with the frame profile 60 to improve the strength and sealing of the air conditioning box 100.

[0073] In the present application, the material of the corner tee profile 50 is reinforced nylon + 30% glass fiber, which greatly improves the tensile strength and bending strength of the corner tee profile 50 and enhances the structural strength of the corner tee profile 50. In addition, the thermal conductivity of the corner tee profile 50 is in the range of 0.26w / (m·k)-0.35w / (m·k), and the thermal conductivity is low, which can effectively block heat transfer and reduce heat loss.

[0074] Preferably, the third sealing plate 52 is made of soft thermal insulation cotton, which is soft and has good impact resistance, can withstand greater extrusion, and has a better sealing effect.

[0075] Furthermore, the main body 51 is configured as a porous structure, which, combined with the material properties of the corner tee profile 50 reinforced with nylon + 30% glass fiber, can improve the tensile strength and bending strength of the corner tee profile 50, ensuring that the corner tee profile 50 has sufficient overall structural strength; at the same time, the main body 51 is configured as a porous structure, which can also greatly save raw materials and reduce costs.

[0076] See also Fig.18A mounting groove 513 is formed on the mounting surface 511, and the third sealing plate 52 is installed in the mounting groove 513, thereby fixing the position of the third sealing plate 52; and part of the third sealing plate 52 extends out from the mounting groove 513 to protrude the body 51 relative to the mounting surface 511; when the corner tee profile 50 and the frame profile 60 are assembled, the third sealing plate 52 can be greatly deformed by mutual extrusion, thereby improving the sealing effect after assembly.

[0077] Furthermore, the corner tee profile 50 also includes a cover plate 53, and each mounting surface 511 has at least one cavity hole 514 that is concave and has an opening 515. The multi-cavity hole 514 structure is adopted to form a hollow structure of the corner tee profile 50, which can enhance the structural strength of the corner tee profile 50 and save material. At the same time, the cover plate 53 is covered at the opening 515 of the corresponding cavity hole 514, and forms a mounting groove 513 with the surrounding side of the mounting surface 511. The cover plate 53 is arranged to cover the opening 515 of the cavity hole 514, which can block the air circulation channel and prevent air from flowing inside the corner tee profile 50 to form cross-wind and cause heat transfer, thereby causing condensation in the box and reducing the service life.

[0078] See also Figure 18-Figure 20 , the connecting piece 54 is matched with the frame profile 60 to further seal the connection and enhance the sealing effect; the frame profile 60 has a first connecting portion 614 corresponding to the connecting piece 54. When the extension arm 512 extends into the frame profile 60 to connect the two to each other, by squeezing the third sealing plate 52, the connecting piece 54 abuts against the corresponding first connecting portion 614, thereby firmly connecting the corner tee profile 50 and the frame profile 60.

[0079] Furthermore, the connecting member 54 includes three plates 55 that are interconnected and vertically arranged, and a mating portion 56 is formed between two adjacent plates 55. Each mating portion 56 and the corresponding extension arm 512 are jointly sealed and connected to the frame profile 60; the mating portion 56 cooperates with the corresponding first connecting portion 614 of the frame profile 60 to further seal the gap between the frame profile 60 and the corner tee profile 50, thereby improving the sealing effect.

[0080] Specifically, see Fig.18 , Fig. 20 and Fig.21 , the edge of each plate 55 has a chamfer 551; when the corner tee profile 50 and the frame profile 60 are assembled, the connecting plate 12 on the frame profile 60 abuts against the plate 55, and a groove 57 is formed between the two at the edge of the plate 55. By filling the sealant 23 in the groove 57, the corner tee profile 50 and the frame profile 60 are sealed again to enhance the connection strength and sealing.

[0081] When the corner tee profile 50 and the frame profile 60 are connected to each other, the extension arm 512 extends into the cavity, and at the same time, the third sealing plate 52 is squeezed by the two to seal the gap between the mounting surface 511 and the frame profile 60; then the sealant 23 is filled in the groove 57 formed at the abutment between the plate 55 and the frame profile 60 for secondary sealing, so that the structural strength of the corner tee profile 50 and the frame profile 60 is higher and the sealing effect is better.

[0082] like Fig.16 As shown, the air conditioning box 100 also includes a frame profile 60, see Fig.16 The frame profile 60 includes a first outer plate 61, a first inner plate 62, a foamed thermal insulation body 63 and two first thermal insulation ribs 64. The first outer plate 61, the first inner plate 62 and the two first thermal insulation ribs 64 form a first chamber 612. The foamed thermal insulation body 63 is filled in the first chamber 612. The first outer plate 61, the first inner plate 62 and the first thermal insulation ribs 64 are bonded together by the foamed thermal insulation body 63 to improve the overall structural strength of the frame profile 60; and the frame profile 60 is transformed into a solid structure by the filling of the foamed thermal insulation body 63, which improves the sealing of the frame profile 60, thereby blocking the air circulation channel of the frame profile 60, preventing air from flowing inside the frame profile 60, forming cross-wind leading to heat transfer, and causing condensation in the box.

[0083] In the present application, the first outer panel 61 and the first inner panel 62 are both made of aluminum alloy molded parts, which can achieve flexibility in the design of the frame profile 60; at the same time, the foam insulation body 63 is a polyurethane foam body with low thermal conductivity.

[0084] Furthermore, two first thermal insulation ribs 64 are arranged adjacent to each other and are respectively connected to the first inner plate 62. Both sides of the first outer plate 61 respectively have second chambers 613, which can enable the first outer plate 61 to form a hollow structure, thereby improving the structural strength of the first outer plate 61 and saving material usage. In addition, first connecting parts 614 are provided at the corresponding second chambers 613 on both sides of the first outer plate 61. The two first thermal insulation ribs 64 are respectively connected to the corresponding first connecting parts 614 on the side away from the first inner plate 62, thereby improving the firmness of the first thermal insulation ribs 64 and the first outer plate 61, further improving the overall structural strength of the frame profile 60. At the same time, the first thermal insulation ribs 64 are not easily damaged due to the external threaded parts 24 passing through the first outer plate 61, thereby improving the service life of the frame profile 60 and the air-conditioning box 100.

[0085] Specifically, in the present application, the first connecting portion 614 is a second card slot, and a second buckle 641 is provided on the first thermal insulation rib 64. The second buckle 641 is snapped into the second card slot, which can improve the firmness of the fixation between the first thermal insulation rib 64 and the first outer panel 61, and further improve the overall structural strength of the frame profile 60.

[0086] See also Figure 6 , Figure 7 and Fig.16 A first connecting cavity 615 is also provided on the first outer panel 61. The first connecting cavity 615 is used to connect the external threaded member 24. The first connecting cavity 615 is arranged adjacent to the second cavity 613 and is not in the same plane as the corresponding first thermal insulation rib 64, thereby avoiding damage to the first thermal insulation rib 64 caused by the threaded member 24 passing through the first connecting cavity 615, thereby improving the service life of the frame profile 60 and the air-conditioning box body 100.

[0087] Furthermore, a first fixing bar 6151 is provided in the first connecting cavity 615, and a certain distance is set between the first fixing bar 6151 and the first heat-insulating rib 64. The first fixing bar 6151 is used to connect the threaded component 24, and a first guiding groove 6152 for guiding the movement of the threaded component 24 is provided on the first fixing bar 6151, which can guide the threading of the threaded component 24 and prevent the threaded component 24 from being easily distorted.

[0088] Preferably, the first guide groove 6152 is a triangular rib groove, the top of which is arranged toward the foam insulation body 63, which can improve the strength of the frame profile 60 and reduce the deformation.

[0089] Specifically, there are multiple first fixing strips 6151, and the multiple first fixing strips 6151 are arranged at intervals in the first connecting cavity 615, and the threaded member 24 is sequentially passed through the multiple first fixing strips 6151 to strengthen the guidance of the threaded member 24 and prevent the threaded member 24 from being distorted; in the present application, the number of first fixing strips 6151 is two. Of course, in other embodiments, the number of first fixing strips 6151 can also be other numbers, such as three, four or five.

[0090] Furthermore, a plurality of third chambers 616 are provided on the first outer panel 61, so that the first outer panel 61 forms a hollow structure, thereby improving the structural strength of the first outer panel 61 and saving material usage; and the third chambers 616 are arranged at intervals between the two second chambers 613 for connecting the corner tee profile 50, thereby improving the strength and sealing of the air-conditioning box body 100.

[0091] See also Fig.16, the width of each first heat-insulating rib 64 ranges from 40mm to 50mm. In the present application, the thermal resistance of the frame profile 60 is further improved by widening the first heat-insulating rib 64, effectively blocking heat transfer and reducing heat loss. Experiments show that when the first heat-insulating rib 64 is set to 40mm-50mm, the thermal resistance and thermal conductivity are small, and the thermal bridge factor of the frame profile 60 can reach the highest level TB1, thereby improving the thermal resistance of the frame profile 60 and increasing the service life of the frame profile 60; preferably, the width of the first heat-insulating rib 64 can also be set to other lengths as needed, such as 42mm, 43mm, 44mm, 45mm, 46mm or 48mm.

[0092] Furthermore, a surface of the first inner plate 62 that is close to the foam insulation 63 and in contact with the foam insulation 63 is a plane 621 , so that the contact area is increased by the plane 621 , thereby enhancing the connection strength between the first inner plate 62 and the foam insulation 63 .

[0093] Furthermore, a plurality of convex edges 622 are provided at intervals on the plane 621. When the foam insulation 63 is injected into the first cavity 612, the convex edges 622 are embedded in the foam insulation 63 to further strengthen the contact with the foam insulation 63 and improve the sealing effect between the first inner panel 62 and the foam insulation 63.

The second outer plate 71, the second inner plate 72 and the second insulation ribs 73 are bonded together by the foamed insulation body 63 to improve the overall structural strength of the intermediate profile 70. In addition, the intermediate profile 70 is transformed into a solid structure by the filling of the foamed insulation body 63, which improves the sealing of the intermediate profile 70, thereby blocking the air circulation channel of the intermediate profile 70, preventing air from flowing inside the intermediate profile 70, forming cross-wind leading to heat transfer, and causing condensation in the box.

[0096] In the present application, the second outer panel 71 is shaped like a "convex" character. Both the second outer panel 71 and the second inner panel 72 are made of aluminum alloy mold parts, which can achieve flexibility in the design of the intermediate profile 70; at the same time, the foam insulation body 63 is a polyurethane foam body with low thermal conductivity.

The two second thermal insulation ribs 73 are respectively connected to the corresponding second connecting portion 714 on the side away from the second inner plate 72, which can improve the firmness of the second thermal insulation ribs 73 and the second outer plate 71, and further improve the overall structural strength of the intermediate profile 70. At the same time, the second thermal insulation ribs 73 are not easily damaged due to the external threaded member 24 passing through the second outer plate 71, thereby improving the service life of the intermediate profile 70 and the air-conditioning box 100.

[0098] Specifically, in the present application, the second connecting portion 714 is a third slot, and a third buckle 731 is provided on the second thermal insulation rib 73. The third buckle 731 is snapped into the third slot, which can improve the firmness of the fixation between the second thermal insulation rib 73 and the second outer panel 71, and further improve the overall structural strength of the intermediate profile 70.

[0099] See also Fig.11 A second connecting cavity 715 is also provided on the second outer plate 71. The second connecting cavity 715 is used to connect the external threaded member 24. The second connecting cavity 715 is arranged adjacent to the fifth chamber 713 and is not in the same plane as the corresponding second thermal insulation rib 73, thereby avoiding damage to the second thermal insulation rib 73 caused by the threaded member 24 passing through the fifth chamber 713, thereby improving the service life of the intermediate profile 70 and the air-conditioning box body 100.

[0100] Furthermore, a second fixing bar 7151 is provided in the second connecting cavity 715. The second fixing bar 7151 is spaced a certain distance from the second thermal insulation rib 73. The second fixing bar 7151 is used to connect the threaded component 24. The second fixing bar 7151 is provided with a second guide groove 7152 for guiding the movement of the threaded component 24, which can guide the threading of the threaded component 24 and prevent the threaded component 24 from being easily distorted.

[0101] Preferably, the second guide groove 7152 is a triangular rib groove, the top of which is arranged toward the foam insulation body 63, which can improve the strength of the intermediate profile 70 and reduce the deformation.
