Among them, the filter is a key component for purifying the circulating air of the air conditioning system and improving the indoor air quality. Its structural design and installation method directly affect the performance of the overall system and the user experience.

[0003] However, the fixing structure between the filter and the filter mounting frame in the existing combined air conditioner is generally in the form of a thin strip spring buckle. After installation, the spring buckle will rebound, resulting in a gap between the filter and the filter mounting frame, resulting in a large bypass air leakage rate. For example, the Chinese patent "A filter mounting frame" with publication number CN 204153953U uses a spring with an elastic steel wire structure to fix the filter, which is prone to the problem of poor sealing between the filter and the mounting frame, resulting in a large bypass air leakage rate.

[0051] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0052] The utility model provides an embodiment of a combined air-conditioning unit. The combined air-conditioning unit is one of the most important equipment for air treatment. It does not have a cold or heat source itself, but uses cold or hot water or steam as a medium to complete the functions of filtering, purifying, heating, cooling, humidifying, dehumidifying, silencing, and fresh air treatment of the air.

[0053] Combined air conditioning unit is a customized air handling equipment, which is the core part of the air conditioning system composed of multiple independent functional sections installed according to a specific air handling process. These functional sections can be flexibly matched according to different environmental requirements and process requirements to meet the air conditioning needs of different occasions.

[0054] The basic structure of the combined air conditioning unit usually includes but is not limited to the following functional sections: a fresh air section, a filtering section 11, a cooling or heating section 12, a humidifying or dehumidifying section 13, and a fan section 14.

[0055] Fresh air enters the combined air-conditioning unit through the fresh air section, passes through the filtering section to filter out dust and debris; then it is cooled or heated through the cooling or heating section to make the air reach the required temperature point, and then it is humidified to the humidity requirement of the system through the humidification section, that is, to reach the specified air supply state point, and finally the treated air is delivered into the room through the fan section.

[0056] like Figure 1-Figure 10 As shown, some embodiments of the present application provide a combined air-conditioning unit.

[0057] The combined air conditioning unit comprises a housing 1, in which a plurality of functional sections are arranged, and the plurality of functional sections at least comprises a filter section 11. The filter section can be a primary filter section, a medium filter section or a high efficiency filter section. The filter section 11 comprises a filter device 200.

[0058] See also Figure 2 and Figure 3 The filtering device 200 includes a mounting frame 210 and a filter 220 mounted on the mounting frame 210 .

[0059] The filter 220 provided in the primary filter section, the medium filter section or the high efficiency filter section corresponds to a coarse filter, a medium filter and a high efficiency filter respectively.

[0060] Specifically, Fig.10 The filter 220 includes a filter material 221 and a filter frame 222 for fixing the filter material 221 .

[0061] For primary filters, the filter materials may include metal mesh, iron filings, ceramic rings, glass fibers and other materials, which can effectively intercept large particles of dust and debris.

[0062] For medium efficiency filters, use finer filter media, such as synthetic fiber or glass fiber filter paper, to capture smaller particles.

[0063] For high-efficiency filters, ultra-fine glass fiber paper is usually used as the filter material, which can capture particles as small as sub-micron level.

[0064] See also Figure 5 The mounting frame 210 includes side panels 211 arranged around and an end panel 212 arranged on one side of the side panel 211 ; the side panels 211 around form a rectangular frame structure, and the end panel 212 is arranged on one side of the frame structure.

[0065] The side plate portion 211 may be provided with a mounting hole for fixing the mounting frame 210 to the housing.

[0066] The filter 220 is disposed in the rectangular frame structure, with one side abutting against the end plate portion 212. The size of the filter frame 222 is slightly smaller than the size of the rectangular frame so that it can be installed in the rectangular frame.

[0067] The filter device 200 further includes a fixing assembly.

[0068] like Figure 4 As shown, the fixing assembly includes an elastic pressing piece 230 and at least one connecting pressing member 240 .

[0069] The elastic pressing piece 230 is located on a side of the filter 220 away from the end plate portion 212 .

[0070] The elastic pressing piece 230 is formed by bending a sheet member, and the elastic pressing piece 230 has a certain width.

[0071] One end of the connecting pressing member 240 is connected to the mounting frame 210 , and the other end is pressed on the elastic pressing sheet 230 , so that the elastic pressing sheet 230 presses the filter 220 , and the filter 220 is pressed and fixed in the mounting frame 210 .

[0072] The connection pressing member 240 may be fixedly connected to the installation frame 210 or detachably connected thereto.

[0073] During installation, the connecting pressing piece 240 is first connected to the installation frame 210, and then the elastic pressing piece 230 is placed close to the filter 220. The elastic pressing piece 230 is pressed to push the elastic pressing piece 230 between the connecting pressing piece 240 and the filter 220, and then the elastic pressing piece 230 is released. The elastic pressing piece 230 will rebound slightly and press the filter 220 through the elastic pressing piece 230.

[0074] Since the elastic pressing sheet 230 continuously generates downward elastic pressure, the filter 220 can be firmly pressed into the mounting frame 210, thereby avoiding a gap between the filter 220 and the mounting frame and reducing the bypass air leakage rate.

[0075] The above-mentioned combined air-conditioning unit uses an elastic pressure piece 230 as a fixed component, which can generate continuous elastic pressure, so that the filter 220 and the mounting frame 210 are in close contact and compression effect, which significantly improves the sealing performance between the two, thereby effectively reducing the potential air leakage rate and ensuring the stability and efficiency of the overall operating performance of the air-conditioning unit.

[0076] At the same time, the elastic pressing piece 230 has a simple structure and can be installed and removed from the connecting pressing piece 240 by pressing the elastic pressing piece 230 , so that the filter 220 can be conveniently and quickly removed from the mounting frame 210 for replacement and maintenance, thereby improving the convenience of disassembly and assembly of the filter 220 .

[0077] In some embodiments of the present application, Fig. 9 As shown, the elastic pressing piece 230 includes a bending boss portion 231 and a pressing foot portion 232 connected to both ends of the bending boss portion 231 .

[0078] The cross section of the bending boss portion 231 is trapezoidal, and the pressure foot portion 232 is extended to both sides parallel to the top surface of the bending boss portion 231, that is, the elastic pressing piece 230 forms a "J"-shaped structure.

[0079] The pressing foot portion 232 is pressed on the filter 220 to abut against the filter 220 .

[0080] The connecting pressing member 240 is pressed on the bent boss portion 231 .

[0081] The width of the elastic pressing sheet 230 is smaller than or equal to the width of the filter frame 222 , so that the elastic pressing sheet 230 can be completely pressed onto the filter frame 222 .

[0082] The elastic pressing sheet 230 has a certain width to ensure the rigidity and stability of the elastic pressing sheet 230 , so that the elastic pressing sheet 230 is more stable and not easy to bend.

[0083] In some embodiments of the present application, the connection pressing member 240 is detachably connected to the installation frame 210 to facilitate installation and disassembly.

[0084] Specifically, Figure 8 As shown, the connecting pressing member 240 includes a pressing rod portion 241 and a connecting rod portion 242 formed by L-shaped bending, and a hook portion 243 formed by bending along one end of the connecting rod portion 242 .

[0085] like Figure 6 A tongue portion 213 is provided on the inner surface of the side plate portion 211 , and a slot is formed between the tongue portion 213 and the inner surface of the side plate portion 211 .

[0086] A hooking groove 2131 is defined on one side of the tongue portion 213 close to the end plate portion 212 .

[0087] During installation, the connecting rod portion 242 is inserted into the slot from one side of the tongue portion 213, and is clamped in the hook slot 2131 through the hook portion 243. When the elastic pressing piece 230 is installed, the pressing rod portion 241 is pressed on the elastic pressing piece 230, so that the connecting pressing piece 240 and the elastic pressing piece 230 are fixed in the installation frame 210.

[0088] In some embodiments of the present application, a plurality of tongue portions 213 are provided, and the plurality of tongue portions 213 are arranged in sequence and spaced apart along the insertion direction of the connecting rod portion 242 .

[0089] By providing a plurality of tongue portions 213 , the hook portion 243 can be engaged with different tongue portions 213 , thereby being suitable for installing filters 220 of different thicknesses.

[0090] In order to further improve the connection stability between the connection pressing member 240 and the elastic pressing sheet 230, as shown in FIG. Figure 1 and Fig. 9 As shown, a slot portion 233 is provided on the elastic pressing piece 230 .

[0091] When the elastic pressing sheet 230 is installed, the elastic pressing sheet 230 is pressed, and the slot portion 233 on the elastic pressing sheet 230 is aligned with the pressing rod portion 241 , and the elastic pressing sheet 230 is inserted into the pressing rod portion 241 .

[0092] The slot portion 233 can not only play a role in installation and positioning, but also limit the displacement of the elastic pressing piece 230 along its length direction, so that the elastic pressing piece 230 is not easy to fall off.

[0093] In some embodiments of the present application, the fixing assembly may include two or more connecting pressing parts 240, which are pressed onto the elastic pressing plate 230 by the multiple connecting pressing parts 240 to improve the overall strength of the connecting pressing parts 240, avoid deformation of the pressing rod portion 241, and ensure that the elastic pressing plate 230 can generate continuous elastic pressure without causing the elastic pressing plate 230 to fail.

[0094] In some embodiments of the present application, Figure 5 As shown, a seal 250 is disposed on the inner side of the end plate 212 , and the seal 250 is in sealing contact with the filter 220 .

[0095] The sealing member 250 is a foamed member, which surrounds the inner side of the end plate 212 and is fixed on the inner side of the end plate 212. The foamed member can be directly formed and fixed on the mounting frame 210 by foaming glue dispensing, that is, foaming directly on the mounting frame 210.

[0096] By providing the sealing member 250, the contact tightness between the filter 220 and the mounting frame 210 is further improved, and the air leakage is further reduced.

[0097] In other embodiments of the present application, the sealing member 250 may be a sealing gasket, a sealing strip, etc.

[0098] In some embodiments of the present application, Figure 4 and Figure 5 As shown, at least one supporting and positioning protrusion 214 is respectively provided on the side plate parts 211 at the four sides. The supporting and positioning protrusion 214 is used to abut against the four sides of the filter 220 to support and limit the filter 220.

[0099] In this embodiment, two supporting and positioning protrusions 214 are disposed on each side plate portion 211 .

[0100] In some embodiments of the present application, the support positioning protrusion 214 is a stamped protrusion formed by stamping the side plate portion 211 , and the stamped protrusion may be a semicircular protrusion.

[0101] In other embodiments of the present application, the support positioning protrusion 214 is a limiting spring piece, and the limiting spring piece can generate elastic deformation under pressure.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
