Referring to fig. 1 to 11, the present application provides an air conditioner case frame 100, the air conditioner case frame 100 is applied to an air conditioner case 200, the air conditioner case 200 is mainly used for receiving and protecting an air conditioner, and the air conditioner case 200 is generally constructed by the air conditioner case frame 100 and a panel 70.

Among the current air conditioning box frame, often lead to the frame to warp because length overlength, be unfavorable for transport transportation and installation, and can lead to the heat transfer when air conditioning box frame splices mutually, cause the condensation of air conditioning box.

In order to solve the problems that the existing air conditioner box body frame is too long to facilitate transportation and installation and heat transfer can be caused when the air conditioner box body frame is spliced with each other, the utility model provides an air conditioner box body frame 100 which comprises a section connecting piece 20 and a plurality of sub frames 101 spliced with each other, wherein each sub frame 101 comprises a section connecting section bar 10, the section connecting piece 20 is installed on the section connecting section bar 10, the section connecting section bar 10 of each sub frame 101 is arranged towards the section connecting section bar 10 of the adjacent sub frame 101 and is connected with each other through the section connecting piece 20, and the section connecting section bar 10 can realize a cold bridge breaking when the plurality of sub frames 101 are spliced with each other.

According to the air-conditioning box body frame 100, the air-conditioning box body frame 100 comprises the plurality of sub frames 101 which are mutually spliced, so that the deformation caused by overlong air-conditioning box body frame 100 is avoided, and the overlong air-conditioning box body frame 100 is not beneficial to carrying, transporting and installing; in addition, the section of connecting section bar can also realize the cold bridge cut-off when a plurality of sub-frames are spliced with each other.

As shown in fig. 2, the air conditioning case frame 100 includes a bezel profile 30, a section connecting profile 10, and an intermediate profile 50. The air conditioner box body frame 100 is roughly in a cuboid shape, and is constructed by the frame section bars 30 and the section connecting section bars 10 along the length, width and height directions of the air conditioner box body frame 100, and the middle section bars 50 are connected between the frame section bars 30 which are arranged in parallel and oppositely for improving the overall strength of the air conditioner box body frame 100.

In some scenes, the required length of the air-conditioning case 200 is not long, and the length of the air-conditioning case frame 100 does not need to be increased by splicing a plurality of sub-frames 101, so that the section connecting profile 10 does not need to be arranged in the air-conditioning case frame 100; as shown in fig. 1, when a sufficiently long air conditioning case frame 100 is required and the length of the air conditioning case frame 100 needs to be increased by splicing a plurality of sub frames 101, it is necessary to provide a segment connecting profile 10 in each sub frame 101, and the segment connecting profile 10 is located at a position where adjacent sub frames 101 are spliced in contact with each other, and in addition, is provided as a frame profile 30, for which reason, the following will be described in detail.

It can be understood that when a plurality of sub-frames 101 need to be spliced, if the section connecting profile 10 is not provided, the sub-frames are simply spliced by contacting the side frame profiles 30, so that a cold bridge is formed at the contact position of the side frame profiles 30 and the side frame profiles 30, thereby forming heat transfer inside and outside the air-conditioning case 200 and forming condensation on the air-conditioning case 200. The reason why this occurs is related to the structure of the frame profile 30.

As shown in fig. 6, the frame profile 30 includes an L-shaped outer plate 31, a second inner plate 32, a first heat insulator 33, and two second heat insulating ribs 34. Two second heat insulation ribs 34 are adjacently arranged, two ends of each second heat insulation rib 34 are respectively connected with the L-shaped outer plate 31 and the second inner plate 32, a first cavity 35 is defined by the L-shaped outer plate 31, the second inner plate 32 and the two second heat insulation ribs 34, and the first heat insulator 33 is filled in the first cavity 35.

The L-shaped outer plate 31 and the second inner plate 32 both adopt aluminum alloy open-die pieces, so that the flexibility of the design of the frame profile 30 can be realized; however, the aluminum alloy mold is a high thermal conductivity material, and the thermal conductivity of the material is about 140w/m.k, so a low thermal conductivity material is required to structurally separate the L-shaped outer plate 31 and the second inner plate 32, so as to improve the thermal resistance of the frame profile 30, thereby effectively blocking heat transfer and reducing heat loss. Therefore, in the present application, the L-shaped outer plate 31 is structurally separated from the second inner plate 32 by two heat insulation ribs; and the heat insulator is a polyurethane foam, so that the heat conductivity coefficient is further reduced.

The L-shaped outer plate 31 is located on the side close to the outer side of the air conditioning case 200, and the second inner plate 32 is located on the side close to the inner side of the air conditioning case 200. It should be noted that the air conditioning cabinet 200 is a rectangular parallelepiped structure with a closed interior, so that the interior of the air conditioning cabinet 200 mentioned in this application refers to the interior surrounded by the air conditioning cabinet 200 for receiving the air conditioner, and is otherwise referred to as the exterior of the air conditioning cabinet 200. The second heat insulation rib 34 is arranged between the L-shaped outer plate 31 and the second inner plate 32, so that heat transfer from the outside of the air-conditioning case 200 to the inside of the air-conditioning case 200 is blocked by the second heat insulation rib 34, thereby realizing a cold bridge of the air-conditioning case 200 and preventing condensation from forming on the surface of the air-conditioning case 200.

However, if the frame profiles 30 of two adjacent sub-frames 101 are spliced in contact with each other, the L-shaped outer plates 31 will contact each other, and since the L-shaped outer plates 31 are both highly heat conductive materials, a heat transfer channel is formed between the inside of the air-conditioning cabinet 200 and the outside of the air-conditioning cabinet 200 due to the contact of the L-shaped outer plates 31, so that heat transfer can be achieved between the inside of the air-conditioning cabinet 200 and the outside of the air-conditioning cabinet 200, thereby forming a cold bridge and generating condensation on the surface of the air-conditioning cabinet 200.

Therefore, in order to avoid this phenomenon, it is necessary to provide a section connecting profile 10 having a different structure from that of the side frame profile 30 in each sub-frame 101, and the specific structure of the section connecting profile 10 is as follows:

as shown in fig. 3, the segment connecting profile 10 includes a first heat insulation rib 11, a first outer plate 12, a first inner plate 13, and a third heat insulator 14.

Wherein the first heat insulation rib 11 is substantially Z-shaped and is disposed between the first outer plate 12 and the first inner plate 13, and when the segment connecting profiles 10 in the adjacent subframes 101 are spliced in contact with each other, the first heat insulation rib 11 blocks heat transfer between the first outer plate 12 and the first inner plate 13. In addition, the first heat insulation rib 11 comprises a first section 111 and a second section 112, two ends of the first section 111 are respectively connected with a first outer plate 12 and a first inner plate 13, and the first outer plate 12 and the first inner plate 13 are positioned on one side of the section connecting section 10 close to the adjacent subframe 101; the two ends of the second section 112 are connected to the first outer plate 12 and the first inner plate 13, respectively, and the second section 112 is located on the side of the section connecting profile 10 away from the adjacent subframe 101. By such an arrangement, heat transfer from the inside to the outside of the air-conditioning case 200 can be blocked by the first section 111 and the second section 112, and when the adjacent sub-frames 101 are spliced with each other, the first heat insulation ribs 11 are in contact with each other, so that heat transfer is not caused, and a cold bridge is prevented from being formed at the joint, thereby realizing the design of a section cold bridge of the air-conditioning case 200.

As shown in fig. 4 and 5, after the segment connecting profiles 10 between the adjacent sub-frames 101 are jointed in contact with each other, the segment connecting profiles 10 jointed in contact with each other are further connected and fixed by the segment connecting member 20.

The fastening portion 21 includes the first protrusion 211 and the first groove 212, and the mating portion 22 includes the second protrusion 221 and the second groove 222, so as to further enhance the connection between the fastening portion 21 and the mating portion 22 by the two portions. In other embodiments, the two-part snap connection is not limited, and the number of the parts for providing the snap connection may be three, four, five or more, which is not limited herein.

Alternatively, the shapes of the buckling part 21 and the matching part 22 may be S-shaped, saw-toothed or L-shaped, which are matched with each other, and the specific shapes of the buckling part 21 and the matching part 22 are not limited herein.

In the present application, the snap-in portion 21 and the mating portion 22 are fixed to the section connecting profile 10 by screws; of course, in other embodiments, the locking portion 21 and the matching portion 22 may also be fixed to the segment connecting section 10 by other methods such as welding, and the like, which is not limited herein.

In order to further enhance the connection reliability after the clamping between the clamping part 21 and the matching part 22, the segment connecting member 20 further comprises a locking member 23, the locking member 23 sequentially penetrates through the clamping part 21 and the matching part 22 and locks the clamping part 21 and the matching part 22, and the clamping part 21 and the matching part 22 are further fixed through the locking member 23, so that the connection strength between the frames 101 is further enhanced. Wherein the locking member 23 is a bolt. Of course, in other embodiments, the locking member 23 may also be other locking members 23 such as a screw, a nut, etc., and is not limited herein.

Mounting holes are formed in the buckling part 21 and the matching part 22, and the buckling part 21 and the matching part 22 are fixed on the section connecting section 10 through the mounting holes in a penetrating mode through screws.

Further, the corner tee 40 includes a body 41. The body 41 has a substantially square shape, and three extension arms 411 extend from three surfaces of the body 41 perpendicular to each other in a direction away from the body 41.

The structure of the multi-die cavity hole 413 is adopted, so that the corner tee piece 40 forms a hollow structure, the structural strength of the corner tee piece 40 can be enhanced, and the material consumption is saved.

Specifically, the corner tee 40 also includes a cover plate 42. The cover plate 42 is made of plastic. The cover plate 42 covers the cavity surface 412 and blocks the cavity hole 413, so as to block the air circulation passage, prevent the air from flowing inside the corner tee 40, and form the wind cross to cause the heat transfer, thereby causing the condensation of the air conditioner box 200 and increasing the heat loss.

Each cover plate 42 is provided with a sealing element 43, and the sealing element 43 is attached to the surface of the cover plate 42 away from the cavity surface 412. When the extension arm 411 extends into the frame profile 30 and extrudes with the frame profile 30, the sealing element 43 deforms under pressure to seal the gap between the cavity surface 412 and the corresponding frame profile 30, so as to improve the sealing effect of the corner three-way element 40 and the frame profile 30, avoid air flowing inside, form air cross to cause heat transfer, cause the box condensation phenomenon, and increase the heat loss of the air conditioning box 200.
