The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art. In addition, when describing a pipeline, the terms "connected" and "connected" as used herein have the meaning of conducting. The specific meaning is to be understood in conjunction with the context.

The air conditioning unit is used as room temperature adjusting equipment, indoor temperature can be adjusted, and comfort level of indoor environment is improved. With the improvement of the living standard of people, people have higher requirements on the living quality, and the air conditioning unit is also widely applied.

Air conditioning units generally include a box plate and a flange. An air outlet is formed in the box plate, and the flange is connected to the air outlet of the box plate and can be connected with an air pipe. In the related art, as shown in fig. 1 and 2, fig. 1 is a schematic structural diagram of a connection between a case plate 010 and a flange 020 in the related art, and fig. 2 is a schematic structural diagram of a connection between another case plate 010 and a flange 020, and the flange 020 is disposed on an air outlet side of the case plate 010 and is connected to the case plate 010.

As shown in fig. 3 and 4, fig. 3 is an exploded view of the case plate 010 and the flange 020 shown in fig. 1, and fig. 4 is an exploded view of the case plate 010 and the flange 020 shown in fig. 2, and the flange 020 may include a plurality of hemming strips 021 and a plurality of flange strips 022. Wherein, a plurality of bordure rectangular 021 sets up in the air outlet 030 department of boxboard 010, is connected with boxboard 010. The flange strips 022 are respectively connected with the edge wrapping strips 021 and are arranged around the air outlet 030 in a circle.

For example, as shown in fig. 3 and 4, the air outlet 030 is rectangular, and the number of bags Bian Changtiao 021 may be four, and the shape is a U-shaped plate. One side wall of the air outlet 030 is clamped in a U-shaped groove of an edge-wrapping strip 021. The flange strip 022 is connected with the edge-wrapping strip 021 and is arranged around the air outlet 030. The installed state thereof can be referred to fig. 1 and 2.

Meanwhile, as shown in fig. 3 and 4, the structure of the plurality of flange strips 022 may be different. For example, a part of the flange strip 022 may be in a U-shape, and the other part of the flange strip 022 may be in a rectangular parallelepiped shape having an opening on one side.

As shown in fig. 3 and 4, the flange 020 has a relatively complex structure, is formed of a plurality of plate-like structures, and has disadvantages of complicated installation and relatively high manufacturing cost. The flange 020 is often screwed or welded to each other.

The screw connection is adopted, so that time and labor are wasted, the appearance looks like a large number of screws, and the appearance is not attractive. When the welding mode is used for connection, silver powder needs to be coated at the welding position for rust prevention, and the appearance is also not attractive.

In addition, sealing cotton is filled between the flange strip 022 and the edge wrapping strip 021, but a gap is still reserved between the flange strip 022 and the edge wrapping strip 021. And for the flange strip 022 of the double air port, the gap between the flange 020 and the box plate 010 is larger at the position without the edge wrapping strip 021. The air flow in the air outlet channel can flow out from the gap, so that the air leakage phenomenon is caused, and the working effect of the air conditioning unit is influenced.

As described above, when the air conditioning unit cools, the flange 020 is cooled by cool air blown out from the air inlet side of the box board 010. As shown in fig. 1 and 2, since the flange 020 is directly connected to the box board 010, cool air of the flange 020 is transferred to the box board 010, thereby causing the air of a relatively high temperature at the outside to be liquefied into dew after contacting the surface of the outside of the box board 010 of a relatively low temperature. The condensation can drip into the room after long-time accumulation, so that the room is moist and even mildewed.

Based on this, an embodiment of the present application provides an air conditioning unit, as shown in fig. 5, fig. 5 is an exploded view of a part of the structure of an air conditioning unit 100 provided in the embodiment of the present application, where the air conditioning unit 100 may include a box board 10, an air outlet flange 20 and a first heat insulation member 30. Wherein, the box board 10 is provided with an air outlet 40, and air flow can flow from one side of the box board 10 to the other side of the box board 10 through the air outlet 40.

As shown in fig. 5, the air outlet flange 20 includes a fixing portion 21 and a main body portion 22. Meanwhile, as shown in fig. 6, fig. 6 is an assembly view of a part of the structure of the air conditioning unit 100 shown in fig. 5, and the fixing portion 21 is provided with a relief hole 211. The fixing portion 21 is located on one side of the box plate 10, and is connected to the box plate 10, and the escape hole 211 is provided opposite to the air outlet 40 (fig. 5). Wherein the fixing portion 21 may be located at the wind inlet side of the box board 10.

As shown in fig. 5, the main body 22 is connected to the fixing portion 21, and is provided around the escape hole 211 (fig. 6).

As shown in fig. 7, fig. 7 is a schematic view of the assembly shown in fig. 6 at another angle, where the main body 22 is disposed through the air outlet 40, and partially extends to the other side of the box board 10.

The first heat insulator 30 (fig. 5) is disposed around the periphery of the main body 22, and has one side attached to the main body 22 and the other side attached to the inner wall of the air outlet 40. Therefore, the main body 22 and the box plate 10 are separated from each other through the first heat insulating member 30, and heat on the main body 22 is not transferred to the box plate 10 through the inner wall of the avoiding hole 211, so that the surface temperature of the air outlet side of the box plate 10 is not too low, and condensation is not easy to form when the air meets external hot air.

For example, as shown in fig. 5, when the air outlet flange 20 is installed, the first heat insulating member 30 may be disposed around the periphery of the main body 22 of the air outlet flange 20, and then the main body 22 of the air outlet flange 20 may be passed through the air outlet 40 on the box board 10, so that the fixing portion 21 abuts against one side of the box board 10. Thus, after the air outlet flange 20 is installed, the first heat insulator 30 can be positioned between the main body 22 and the box plate 10, and the gap between the main body 22 and the box plate 10 can be filled.

It will be appreciated that the air outlet flange 20 may be connected to the air duct, as shown in fig. 8, and fig. 8 is a schematic structural diagram of the air outlet flange 20 (fig. 5) when connected to the air duct 50, and the main body 22 (fig. 7) of the air outlet flange 20 may be located inside the air duct 50 and connected to the air duct 50. Cold air blown out of the box board 10 can enter the air duct 50 for transmission.

In some embodiments, the first insulation 30 may be made of a flexible material, with an interference fit between the first insulation 30 and the box board 10. This ensures that the gap between the main body 22 and the box 10 is filled with the first heat insulator 30, and separates the main body 22 from the box, thereby realizing a bridge cut-off. And further, the cold air in the air conditioning unit 100 is prevented from being transmitted to the box board 10 through the main body 22, and the problem that the box board 10 is condensed due to the cooler temperature transmitted from the air outlet flange 20 is solved.

In some embodiments, as shown in fig. 5, the air conditioning unit 100 may further include a second insulation 60. Meanwhile, as shown in fig. 7, the second heat insulator 60 is located at a side of the box board 10 away from the fixing portion 21 (fig. 6). The second heat insulator 60 is provided around the periphery of the portion of the main body 22 extending out of the box board 10, and is attached to the main body 22. It will be appreciated that when the air outlet flange 20 is connected to the air duct 50, the side of the second insulating member 60 remote from the main body 22 may be in contact with the inner wall of the air duct 50.

The second heat insulator 60 wraps the portion of the main body 22 extending out of the box board 10, and when cold air passes through the main body 22, the main body 22 is cooled by the cold air, and a temperature difference is formed between the air outlet 40 and the air temperature outside the box board 10. However, since the second heat insulator 60 is provided around the periphery of the main body 22, air having a relatively high temperature outside can only contact the second heat insulator 60 having an insulation temperature, but does not contact the main body 22 having a relatively low temperature, and therefore condensation is less likely to occur on the outside of the main body 22 away from the air outlet 40.

In some embodiments, the first insulation 30 may be a PE insulation. The PE material has a good heat insulation performance, and can well keep the temperature stable, and the PE material of the first heat insulating member 30 can well insulate the temperature of the main body 22 itself, and prevent the condensation generated by the contact of the external steam and the low-temperature main body 22.

In addition, since the first heat insulator 30 and the box 10 may be in interference connection, the first heat insulator 30 made of PE can be well fitted between the body 22 and the space of the box 10, thereby achieving interference fit.

In some embodiments, as shown in fig. 9, fig. 9 is a schematic diagram of a connection structure between another box board 10 and an air outlet flange 20 according to an embodiment of the present application, and the number of air outlets 40 and air outlet flanges 20 may be plural. The plurality of air outlets 40 are disposed at intervals along the first direction X. The main body 22 of one air outlet flange 20 is disposed through one air outlet 40.

As shown in fig. 9 and 10, fig. 10 is an exploded view of another case plate 10 shown in fig. 9 connected to the air outlet flange 20, and the air conditioning unit 100 further includes a second heat insulating member 60 and a plurality of third heat insulating members 70. The second heat insulator 60 is located on the side of the box board 10 remote from the fixing portion 21. The second heat insulator 60 is provided around the periphery of the portion of the plurality of main body portions 22 extending out of the box plate 10, and is attached to the plurality of main body portions 22.

Meanwhile, as shown in fig. 10, a plurality of third heat insulators 70 are located at a side of the box board 10 away from the fixing portion 21, and are distributed between adjacent two main body portions 22. As shown in fig. 9, the surfaces of the adjacent two main body portions 22 on the sides close to each other are respectively attached with a third heat insulator 70, and both ends of the third heat insulator 70 in the second direction Y (fig. 9) are respectively abutted against the second heat insulator 60. The second direction Y is perpendicular to the first direction X (fig. 9) and parallel to the box board 10.

As shown in fig. 9, when the air outlet 40 and the air outlet flange 20 are plural, the second heat insulator 60 may surround the portion of the plurality of main body portions 22 extending beyond the periphery of the box plate 10 at the same time. Meanwhile, the plurality of third heat insulators 70 can isolate the portion of the main body 22 that cannot be insulated by the second heat insulator 60 from the outside, so that all the portion of the main body 22 extending out of the box board 10 can be insulated, and condensation is not easy to form on the main body 22.

For example, the first heat insulator 30 and the main body 22, the second heat insulator 60 and the portion of the main body 22 extending beyond the box plate 10, and the third heat insulator 70 and two adjacent main body 22 may be connected by adhesive means. The first heat insulator 30, the second heat insulator 60, and the third heat insulator 70 are not easily damaged, and can be connected to the main body 22 while maintaining their own performance.

In some embodiments, as shown in FIG. 10, the air conditioning unit 100 may also include a plurality of connectors 80. As shown in fig. 9, the plurality of connectors 80 are located on the side of the box board 10 away from the fixing portion 21, are distributed between two adjacent main body portions 22, and are connected to the main body portions 22. Wherein, two connecting pieces 80 are distributed between two adjacent main body portions 22 at intervals along the second direction Y, and the connecting pieces 80 are abutted against the second heat insulating piece 60. When there are a plurality of air outlets 40 and air outlet flanges 20, the adjacent main body portions 22 may be connected by the connection members 80, enhancing stability between the plurality of air outlet flanges 20.

For example, as shown in fig. 10, the connecting member 80 may further be provided with a first connecting hole 801, and the first connecting hole 801 is located on both sides of the connecting member 80 adjacent to the two main body portions 22. Meanwhile, at a position of the body portion 22 corresponding to the first connection hole 801, a second connection hole 2201 may be opened. The screw passes through the first connection hole 801 and the second connection hole 2201 to fixedly connect the connector 80 with the main body portion 22. The screw connection is relatively firm, and the connecting member 80 can be firmly fixed between two adjacent main body portions 22.

It will be appreciated that when the spacing between adjacent two body portions 22 is greater, the length of the connector 80 is also greater. At this time, the connecting member 80 may be connected to the adjacent two main body portions 22 by screws, and the connecting member 80 may be connected to the box board 10 by screws on the side where the connecting member 80 is attached to the box board 10, thereby further securing the stability of the connecting member 80.

As shown in fig. 11, fig. 11 is an assembly view of a part of the structure of the box board 10 and the air outlet flange 20 shown in fig. 9, after the main body 22 and the first heat insulator 30 (fig. 10) pass through the air outlet 40 on the box board 10, the fixing portion 21 is abutted against one side of the box board 10, and then the dovetail nail can be used to fix the main body 22 and the box board 10. The air outlet flange 20 can thereby be fastened to the box plate 10. Meanwhile, the dovetail nails are used for connecting firmly, so that the air outlet flange 20 is prevented from falling off the box plate 10.

In some embodiments, the third thermal shield 70 may be made of a flexible material. At this time, the connection member 80 and the third heat insulating member 70 may be in an interference state, that is, the third heat insulating member 70 is in a compressed state. In this way, the connecting member 80 can enhance the strength between the adjacent air outlet flanges 20 and can better fit between the third heat insulating member 70 and the main body 22.

In some embodiments, the second thermal shield 60 is an XPE thermal shield. Because the combination of XPE materials includes a better expansion than PE materials, and the material of the second thermal insulation member 60 is XPE, the second thermal insulation member 60 is able to surround a portion of the first thermal insulation member 30 extending away from the fixing portion 21 of the box board 10 with the better expansion of XPE.

Meanwhile, because the XPE material is relatively soft, the XPE between two adjacent main body portions 22 will bend to a certain extent, and therefore the connecting piece 80 that is located between two main body portions 22 and abuts against the second heat insulating piece 60 can play a certain supporting role on the second heat insulating piece 60.

Further, it is understood that the thickness of the first and second heat insulators 30 and 60 may be designed according to practical situations. In practice, the clearance between the main body 22 and the inner wall of the outlet 40 is typically less than 2mm. Accordingly, the thickness of the first heat insulating member 30 may be 2mm, so that the first heat insulating member 30 can be in a compressed state to better fill the gap between the main body portion 22 and the inner wall of the air outlet 40.

Similarly, the clearance between the main body portion 22 and the inner wall of the air duct 50 is typically less than 5mm. Accordingly, the thickness of the second heat insulating member 60 may be 5mm, thereby enabling the second heat insulating member 60 to be in a compressed state to better fill the gap between the main body portion 22 and the inner wall of the duct 50.

In some embodiments, as shown in fig. 12 and 13, fig. 12 is a cross-sectional view of the first and second insulation members 30, 60 and the box plate 10, and fig. 13 is a partial enlarged view at a in fig. 12, a portion of the first insulation member 30 may protrude to a side of the box plate 10 away from the fixing portion 21 (fig. 11). The first heat insulator 30 extends to a side of the case plate 10 away from the fixing portion 21, so that it is ensured that the gap between the main body portion 22 and the case plate 10 can be completely filled, and external water vapor is prevented from contacting the main body portion 22 and the case plate 10, which are relatively low in temperature, through the gap, thereby generating condensation at the gap.

Meanwhile, as shown in fig. 13, a portion of the second heat insulating member 60 is disposed around the periphery of the portion of the first heat insulating member 30 extending out of the side of the box board 10. The second heat insulator 60 surrounds a portion of the first heat insulator 30 extending to the case plate 10 away from the fixing portion 21 (fig. 11), and is provided so as to overlap the first heat insulator 30, thereby further preventing the main body 22 (fig. 11) from coming into contact with an external machine and preventing the occurrence of condensation.

In some embodiments, as shown in fig. 14, fig. 14 is a schematic structural diagram of an air outlet flange 20 of an air conditioning unit 100 according to an embodiment of the present application, and the air outlet flange 20 may include a plurality of connection portions 23. The plurality of connection portions 23 are detachably connected end to end in sequence and are respectively connected with the box board 10. A part of the connecting portion 23 forms a part of the main body portion 22 (fig. 10), and another part forms a part of the fixing portion 21 (fig. 10).

The air outlet flange 20 is divided into the plurality of connecting parts 23, when the air outlet flange is assembled, only the corresponding number of parts are required to be installed according to the size of the air outlet 40 on the box plate 10, when one part of the air outlet flange 20 is damaged, the whole air outlet flange 20 does not need to be replaced, and the main part needs to replace the corresponding damaged connecting parts 23, so that the maintenance cost is reduced. Meanwhile, the structure of the single connecting part 23 is simpler than that of the whole structure, so that the processing flow can be simplified, and the processing is more convenient.

The fixing portion 21 and the main body portion 22 are integrally provided, so that the main body portion 22 is not easily separated from the fixing portion 21 after the fixing portion 21 and the box board 10 are adhered and fixed, and the stability of the air outlet flange 20 is ensured.

In some embodiments, as shown in fig. 14, the plurality of connection parts 23 may include two first connection parts 231 and two second connection parts 232. The two first connection parts 231 are disposed at intervals along the first direction X. The two second connection portions 232 are disposed at intervals along the second direction Y. The second direction Y is perpendicular to the first direction X and is parallel to the box board 10. Thus, the two first connection parts 231 and the two second connection parts 232 may be alternately connected to form the air outlet flange 20.

The first connection portion 231 includes a first fixing portion 2311 and a first body portion 2312. The first body portion 2312 is located at one side of the first fixing portion 2311 and is connected to the first fixing portion 2311. The second connection portion 232 may include a second fixing portion 2321 and a second body portion 2322.

Two ends of the two first fixing portions 2311 respectively abut against the two second fixing portions 2321, and are spliced to form the fixing portion 21. The two second body portions 2322 are respectively bent at two ends along the first direction X and located at one side of the two first body portions 2312 away from each other, and are connected to the first body portions 2312.

Thus, the first body 2312 and the second body 2322 are sequentially connected, and can be enclosed into a rectangular shape.

Accordingly, the two first fixing portions 2311 can be engaged with the positions where the two second fixing portions 2321 are bent toward the two first fixing portions 2311, so that the connection between the first fixing portions 2311 and the second fixing portions 2321 is more tight. The second body portion 2322 is located at one side of the second fixing portion 2321, and is connected to the second fixing portion 2321.

For example, as shown in fig. 14, the included angle between the first fixing portion 2311 and the first body portion 2312 and the included angle between the second fixing portion 2321 and the second body portion 2322 may be 90 °. Accordingly, after the fixing portion 21 is connected to the box 10, the two first body portions 2312 and the two second body portions 2322 can be parallel to each other, and the parallel body portions 22 can prevent gaps from being formed in the connection between the second heat insulator 60 and the body portions 22, and condensation is less likely to occur.

In some embodiments, one of the first body portion 2312 and the second body portion 2322 may be provided with a staking recess, the other one being provided with a staking portion. The caulking portion is caulking to the caulking recess. The connecting mode can reduce the installation quantity of parts and reduce the manufacturing cost. For example, the first body portion 2312 and the second body portion 2322 may be fixedly connected using a TOX riveting process.

For example, a plurality of caulking recesses may be provided on the first body portion 2312 or a portion of the second body portion 2322 bent toward the first body portion 2312, and a corresponding caulking portion may be provided on another portion.

In some embodiments, the box board 10 may include a first substrate layer, an insulation layer, and a second substrate layer. The first base layer is connected to the fixing portion 21. The heat insulating layer is laminated on one side of the first base layer away from the fixing portion 21. The heat insulation layer is used for isolating heat. The second substrate layer is stacked on one side of the heat insulation layer away from the first substrate layer.

The side of the box board 10 near the fixing portion 21 is located inside the air conditioning unit 100, and the temperature inside the air conditioning unit 100 is relatively low with respect to the temperature outside the air conditioning unit 100 due to the generation of cool air. The low temperature air in the air conditioning unit 100 may lower the temperature of the first base layer, and the low temperature of the first base layer is not transferred to the second base layer because the inside of the case plate 10 has the heat insulation layer, so that the side of the case plate 10 away from the fixing plate may not generate condensation due to the temperature difference with the outside air.

The material of the heat insulating layer is not particularly limited, and the heat insulating layer can achieve the heat insulating effect.

Illustratively, the air outlet flange 20, the first substrate layer and the second substrate layer may be metal plates, which have high strength and are not easy to damage, so that the air conditioning unit 100 can be well protected. Thus, the heat insulating layer is provided in the middle of the box plate 10, so that the metal box plate 10 can be further prevented from being exposed, and the box plate 10 can be prevented from being exposed, and can have sufficient durability.

The foregoing is merely illustrative of specific embodiments of the present application, and the scope of the present application is not limited thereto, but any changes or substitutions within the technical scope of the present application should be covered by the scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
