Description

Technical Field

[0002] At present, modular air conditioning units are widely used in various building environments as air conditioning equipment, and their performance and operating efficiency have attracted much attention. 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 design of the filter installation frame in the existing combined air conditioner has technical problems such as inconvenient filter removal and poor sealing between the filter and the installation frame. For example, the Chinese patent "A filter frame" with publication number CN206890789U sets triangular fixing plates at the four corners of the filter frame, sets bolts on the triangular fixing plates, adopts bolt locking method, and presses the filter with the bolts at the four corners of the filter frame to tightly fit the filter on the filter frame. When the filter needs to be replaced, the fastening bolts at the four corners need to be loosened one by one, and then the triangular fixing plate is removed to remove the filter. The filter element frame and the filter are sealed by fastening bolts, so that there may be gaps between the filter and the filter element frame due to the fastening bolts not being twisted into place or the fastening bolts being loose, which may cause air leakage and reduce the filtering effect.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] like Figure 1-Figure 10 As shown, some embodiments of the present application provide a combined air-conditioning unit.

[0059] 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.

[0060] See also Figure 1 and Figure 2 The filtering device 200 includes a mounting frame 210 and a filter 220 mounted on the mounting frame 210 .

[0061] 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.

[0062] Specifically, Fig.11 The filter 220 includes a filter material 221 and a filter frame 222 for fixing the filter material 221 .

[0063] 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.

[0064] For medium efficiency filters, use finer filter media, such as synthetic fiber or glass fiber filter paper, to capture smaller particles.

[0065] 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.

[0066] See also Fig.10 The mounting frame 210 includes side panels 211 arranged around and an end panel 214 arranged on one side of the side panel 211 ; the side panels 211 around form a rectangular frame structure, and the end panel 214 is arranged on one side of the frame structure.

[0067] The side plate portion 211 is provided with a mounting hole 215 for fixing the mounting frame 210 to the housing.

[0068] The filter 220 is disposed in the rectangular frame structure, with one side abutting against the end plate portion 214. 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.

[0069] like Figure 3-Figure 8 As shown, four corners of the mounting frame 210 are respectively provided with mounting components 230 .

[0070] Specifically, the installation assembly 230 includes a limiting member 231 and an elastic element 232 fixedly connected to the limiting member 231 .

[0071] The side plates 211 of the mounting frame 210 are provided with limiting portions 212 near the corners.

[0072] The limiting member 231 cooperates with the limiting portion 212 and is pressed onto the filter 220 through the elastic element 232 , so that the filter 220 is in sealing contact with the inner side surface of the end plate portion 214 of the mounting frame 210 .

[0073] When the stopper 231 is pushed toward the filter 220, the elastic element 232 is compressed, and the stopper 231 can be separated from the stopper 212, and the mounting assembly 230 can be removed. When all the mounting assemblies 230 at the four corners are removed, the filter 220 can be taken out of the mounting frame 210.

[0074] The above-mentioned combined air conditioning unit can easily remove the installation component 230 by simply pushing the installation component 230, and then the filter 220 can be conveniently and quickly removed from the installation frame 210 for replacement and maintenance, thereby improving the convenience of disassembly and assembly of the filter 220.

[0075] At the same time, the installation component 230 uses an elastic element 232, and the elastic element 232 has a moderate elastic compression space, which can be compatible with and adapt to the installation of filters 220 with different thickness specifications.

[0076] Moreover, the close contact and compression effect generated by the elastic element 232 between the filter 220 and the mounting frame 210 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.

[0077] In some embodiments of the present application, the elastic element 232 is a spring, which can be a coil spring, a spring leaf, etc.

[0078] One end of the spring is fixedly connected to the limiting member 231 , and the other end of the spring abuts against the filter 220 .

[0079] Specifically, Figure 6 and Figure 8 As shown, the limiting member 231 is a sheet metal member, on which a rivet nut 233 is fixed, and a limiting bolt column 234 is fixed on the rivet nut 233. The spring is sleeved on the limiting bolt column 234 and is welded and fixed to the limiting bolt column 234.

[0080] In other embodiments of the present application, the rivet nut 233 and the limiting member 231 may be an integral structure.

[0081] In some other embodiments of the present application, a threaded hole with an internal thread may be provided on the limiting member 231 for fixed connection with the limiting bolt column 234 .

[0082] In some embodiments of the present application, in order to increase the contact area between the end face of the elastic element 232 and the filter 220 so that the elastic element 232 can have a stable pressing effect, the installation assembly 230 also includes an abutment 235, which is fixedly connected to one end of the spring close to the filter 220, and the spring abuts against the filter 220 through the abutment 235.

[0083] The abutment member 235 can be a gasket, which is welded and fixed to one end of the spring. The gasket can be in a circular, oval, square or other shape.

[0084] In some embodiments of the present application, a limiting portion 212 is respectively disposed at the corner positions of the two adjacent side plates 211 .

[0085] The limiting portion 212 is provided with a limiting groove, and the notch of the limiting groove faces the filter 220 .

[0086] The limiting member 231 is disposed between the two connected side plates 211 and is perpendicular to the two side plates 211 .

[0087] like Figure 8 As shown, an inserting portion 2311 is respectively disposed at both ends of the limiting member 231 , and the inserting portion 2311 is disposed at a side of the limiting member 231 away from the filter 220 .

[0088] The inserting portions 2311 at both ends of the limiting member 231 are respectively inserted into the limiting grooves on the two side plates 211 .

[0089] The plug-in portion 2311 is inserted into the limiting groove, which can limit the displacement of the limiting member 231 except the plug-in direction.

[0090] When the limiting member 231 is pushed toward the direction approaching the filter 220, the plug-in portion 2311 can move in the plug-in slot toward the direction approaching the filter 220. When completely detached from the plug-in slot, the limiting portion 212 releases the limiting of the limiting member 231, and the installation assembly 230 can be removed from the installation frame 210.

[0091] In some embodiments of the present application, the limiting portion 212 is an L-shaped bent plate, and a limiting groove is formed between the L-shaped bent plate and the inner side surface of the side plate.

[0092] The limiting member 231 is a limiting plate, and two ends of the limiting plate close to the side plate portion 211 are bent toward a side away from the filter 220 to form an inserting portion 2311 .

[0093] The limiting plate can be a triangular plate or a trapezoidal plate.

[0094] The installation component 230 provides a convenient installation and disassembly method. At the same time, the limit members 231 are set at the four corners, which also ensures a certain supporting strength, provides a certain strength and pressure resistance, so that the filter 220 component can ensure strength under high wind pressure and high air volume conditions.

[0095] In some embodiments of the present application, Figure 6 and Figure 8 As shown, a seal 240 is disposed on the inner side of the end plate 214 , and the seal 240 is in sealing contact with the filter 220 .

[0096] The sealing member 240 is a foamed member, which surrounds the inner side of the end plate 214 and is fixed on the inner side of the end plate 214. 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.

[0097] By providing the sealing member 240, the contact tightness between the filter 220 and the mounting frame 210 is further improved, and the air leakage is further reduced.

[0098] In other embodiments of the present application, the sealing member 240 may be a sealing gasket, a sealing strip, etc.

[0099] In some embodiments of the present application, Fig. 9 As shown, at least one supporting and positioning protrusion 213 is respectively provided on the side plate portions 211 around. In this embodiment, two supporting and positioning protrusions 213 are provided on each side plate portion 211.

[0100] The support and positioning protrusion 213 is a spring sheet structure and can be elastically deformed when pressed.

[0101] When installing the filter 220, the filter 220 is pushed, and the frame of the filter 220 can produce a small elastic deformation by squeezing the support positioning protrusions 213, and the frame of the filter 220 is positioned between each support positioning protrusion 213, and the filter 220 is positioned and installed in the installation frame 210. The filter 220 is pre-fixed by the support positioning protrusions 213, which is convenient for the subsequent installation and fixation of the installation assembly 230.

[0102] When the filter 220 is disassembled, the installation components 230 at the four corners are removed, and the filter 220 is pushed in the reverse direction, so that the filter 220 can be separated from the installation frame 210 .

[0103] Furthermore, one side of the supporting positioning protrusion 213 has a slope to facilitate pushing of the filter 220 .

[0104] 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. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.

[0105] For the convenience of explanation, the above description has been made in conjunction with specific embodiments. However, the above exemplary discussion is not intended to be exhaustive or limit the embodiments to the specific forms disclosed above. Based on the above teachings, various modifications and variations can be obtained. The selection and description of the above embodiments are to better explain the principles and practical applications, so that those skilled in the art can better use the embodiments and various different variations of the embodiments suitable for specific use considerations.
