[0054] In this application, the air conditioner performs a refrigeration cycle by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat the indoor space.

[0055] The low-temperature and low-pressure refrigerant enters the compressor, and the compressor compresses it into a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0056] The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant formed by condensation in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by using the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0057] The outdoor unit of the air conditioner refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger. The indoor unit of the air conditioner includes an indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0058] The indoor heat exchanger and the outdoor heat exchanger are used as condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner serves as a heater in the heating mode. When the indoor heat exchanger is used as an evaporator, the air conditioner serves as a cooler in the cooling mode.

[0059] Reference Figure 1 , this application proposes a combined air-conditioning unit, which includes a housing 100, a heat exchanger 300, and a filter assembly 200. An air inlet and an air outlet are formed on the housing 100, and an air intake passage is formed between the air inlet and the air outlet.

[0060] The air inlet is used to introduce external air flow. The external air flow is transported from the air inlet into the air intake passage and output to the indoor through the air outlet.

[0061] A blower component 400 is formed inside the air outlet for driving air flow.

[0062] The heat exchanger 300 and the filter assembly 200 are both arranged in the air intake passage. The heat exchanger 300 is used for heat exchange of the air flow passing through it, and the filter assembly 200 is used for filtering dust and impurities in the air flow or performing sterilization treatment on the passing air flow.

[0063] Reference Figure 2 、 Figure 3 Specifically, the filter assembly 200 is located at the output end of the heat exchanger 300. The filter assembly 200 includes a flexible connecting member 220, a folding bracket assembly 230, and a filter element 240. The folding bracket assembly 230 is connected to the flexible connecting member 220, and the filter element 240 is arranged on the folding bracket assembly 230.

[0064] The flexible connecting member 220 is detachably connected to the support member 210. The flexible connecting member 220 includes at least two parallel flexible transverse portions 221.

[0065] Reference Figures 4 - 6 There is a space between the two flexible transverse portions 221. Specifically, they are respectively fixed at the upper and lower ends or the left and right ends of the air intake passage.

[0066] The folding bracket assembly 230 includes multiple groups of bracket units 231 arranged along the length direction of the flexible transverse portion 221. When the two flexible transverse portions 221 are respectively arranged at the upper and lower ends of the air intake passage, the groups of bracket units 231 in the folding bracket assembly 230 are arranged along the height direction of the air intake passage. When the two flexible transverse portions 221 are respectively arranged at the left and right ends of the air intake passage, the groups of bracket units 231 in the folding bracket assembly 230 are arranged along the width direction of the air intake passage.

[0067] The filter element 240 is laid above the folding bracket assembly 230, and the filter element 240 is selected according to the actual filtering effect of the filter assembly 200 (such as primary filtration or medium filtration, etc.).

[0068] Specifically, the filter element 240 is a filter element, and it can be folded along with the folding bracket assembly 230 and the flexible transverse portion 221.

[0069] Among them, reference Figures 7 - 9 Each group of bracket units 231 includes a bracket transverse portion 232 and a diagonal brace portion 233. The bracket transverse portion 232 is specifically a crossbar structure, and the cross-sectional shape of the crossbar is circular or other shapes.

[0070] The bracket transverse portion 232 is vertically arranged between the two flexible transverse portions 221, that is, the extending direction of the flexible transverse portion 221 is perpendicular to the bracket transverse portion 232.

[0071] At both ends of the horizontal part 232 of the bracket, at least two angled brace parts 233 are rotatably connected respectively, and the bottom of each brace part 233 is connected to the corresponding flexible horizontal part 221.

[0072] The brace parts 233 located at the same end of the horizontal part 232 of the bracket can rotate at an angle along the horizontal part 232 of the bracket, and each brace part 233 rotates around the corresponding horizontal part 232 of the bracket to realize the unfolding or gathering of the filtering assembly 200.

[0073] During the rotation of the brace part 233 along the horizontal part 232 of the bracket, the flexible horizontal part 221 connected to its bottom unfolds or gathers accordingly.

[0074] In addition to the folding movement of the brace part 233, each bracket unit 231 can also gather together with the flexible horizontal part 221, which is convenient for storage and transportation.

[0075] In some embodiments of the present application, a plurality of fixed horizontal parts 234 are arranged at intervals on the flexible horizontal part 221, and the bottom of each brace part 233 is rotatably connected to the fixed horizontal part 234.

[0076] The fixed horizontal part 234 is connected to the flexible horizontal part 221 by means of pasting or stitching.

[0077] Each brace part 233 can correspond to a fixed horizontal part 234, or when two brace parts 233 are respectively arranged at the end parts of the horizontal part 232 of the bracket, the adjacent brace parts 233 on the adjacent bracket units 231 are respectively connected to the first rotating parts 2341 at both ends of the same fixed horizontal part 234.

[0078] Specifically, in combination with Figure 10 , first rotating parts 2341 are respectively formed at both ends of the fixed horizontal part 234, second rotating parts 2331 are formed at the bottom of each brace part 233, and the second rotating part 2331 is rotatably connected to the corresponding first rotating part 2341.

[0079] For the convenience of connection and positioning, a rotation gap 2343 is further formed on the first rotating parts 2341 at both ends of the fixed horizontal part 234 in the present application. The second rotating part 2331 is connected within the corresponding rotation gap 2343, and a connecting shaft penetrates through the second rotating part 2331 and the first rotating parts 2341 on both sides of the rotation gap 2343, thereby realizing the connection between the first rotating part 2341 and the second rotating part 2331.

[0080] For the convenience of processing, the size of the rotation gap 2343 is designed to be not less than the thickness of the two first rotating parts 2341, so that the first rotating parts 2341 on the two brace parts 233 arranged front and back along the horizontal part 232 of the bracket can be positioned within the rotation gap 2343.

[0081] A reinforcing portion 235 is further disposed between the two flexible transverse portions 221 . Specifically, two ends of the reinforcing portion 235 are respectively fixed on two opposite fixed transverse portions 234 of the two flexible transverse portions 221 .

[0082] The reinforcing portion 235 is parallel to the bracket transverse portion 232 , and the fixed transverse portion 234 and the reinforcing portion 235 are connected and fixed to the flexible transverse portion 221 by sutures.

[0083] The filter element 240 is fixed on the bracket cross section 232 and the reinforcement section 235. Specifically, a plurality of folded sections parallel to the bracket cross section 232 are formed on the filter element 240. Each folded section is connected to the corresponding bracket cross section 232 and the reinforcement section 235. The filter element 240 is folded back and forth between the bracket cross section 232 and the reinforcement section 235.

[0084] In other words, the filter element 240 covering the surface of the folding bracket assembly 230 is arranged in a continuous W shape under the action of the bracket cross portion 232 and the reinforcement portion 235, so as to increase the filtering area of ​​the filter element 240 and improve the filtering efficiency.

[0085] When the filter assembly 200 is in a folded and gathered state, the filter element 240 is retracted inward along its folded portion to reduce the overall size of the filter assembly 200. When it needs to be assembled into the air inlet channel, the filter element 240, the folding bracket assembly 230 and the flexible connector 220 are simultaneously unfolded.

[0086] The connection between the filter element 240 and the bracket cross portion 232 and the reinforcement portion 235 is fixed by sutures, or can also be fixed by fastening nails or the like.

[0087] The reinforcing portion 235 and the supporting cross portion are both made of metal or other structures, which support the entire filter assembly 200. When the filter assembly 200 is gathered, its gathering direction is perpendicular to the direction of the reinforcing portion 235 and the supporting cross portion, and will not affect the structure of the reinforcing portion 235 and the supporting cross portion.

[0088] A first connection hole 2342 is formed on the fixed transverse portion 234 , and second connection holes 2351 corresponding to the positions of the first connection holes 2342 are formed at both ends of the reinforcing portion 235 . The second rotating portion 2331 and the first rotating portion 2341 are connected via a rotating shaft 236 .

[0089] A first connection hole 2342 is formed on the fixed transverse portion 234 , and second connection holes 2351 corresponding to the positions of the first connection holes 2342 are formed at both ends of the reinforcement portion 235 . The fixed transverse portion 234 and the reinforcement portion 235 are connected and fixed to the flexible transverse portion 221 by sutures.

[0090] In some embodiments of the present application, since the filter element 240 is laid on the surface of the folding bracket assembly 230 and the two sides of the folding bracket assembly 230 are hollow structures, in order to ensure the filtering effect and prevent unfiltered air flow from being output from the sides of the folding bracket assembly 230, the present application further provides filter ends 237 at both ends of the bracket unit 231. The filter ends 237 are used to block both ends of the filter element 240.

[0091] The end face shape of the filter end 237 is triangular. Its two sides are connected to the diagonal braces 233 on both sides of each bracket unit 231, and the end face covers the space between the corresponding two diagonal braces 233. The filter end 237 and the filter element 240 cooperate to filter the flowing air flow in all directions.

[0092] In some embodiments of the present application, the flexible connecting member 220 further includes a flexible longitudinal portion 222. The flexible longitudinal portions 222 are respectively and perpendicularly connected between the two flexible transverse portions 221, and the flexible transverse portions 221 and the flexible longitudinal portions 222 are connected to form a frame structure.

[0093] The material of the flexible longitudinal portion 222 can be the same as that of the flexible transverse portion 221 and both are flexible. Alternatively, the material of the flexible longitudinal portion 222 can also be a rigid material such as metal or plastic.

[0094] The present application provides a connection basis for the filter element 240 through the flexible connecting member 220, without relying on a traditional metal frame, which is beneficial to reducing the consumption of raw materials and reducing the weight and cost of the filter assembly 200.

[0095] The support member 210 is a support frame structure fixed in the air inlet passage. A flexible fixing member is formed on the support frame. The flexible fixing member and the flexible connecting member 220 form a Velcro structure to realize the detachable connection of the flexible connecting member 220 to the flexible fixing member.

[0096] Specifically, one of the flexible connecting member 220 and the flexible fixing member forms a fuzzy surface, and the other forms a hook surface. The other side of the flexible fixing member is fixed to the support member 210 through glue or the like. Then, the filter assembly 200 can be directly pasted on the flexible fixing member by means of Velcro connection, without relying on structures such as fastening screws and hooks. The flexible transverse portion 221 and the flexible longitudinal portion 222 of the flexible connecting member 220 seal the periphery of the filter assembly 200 by means of Velcro, which can also improve the connection tightness and the filtering effect.

[0097] On the other hand, the present application further provides a combined air conditioner unit, which includes a housing 100, a heat exchanger 300, and a filter assembly 200.

[0098] An air inlet and an air outlet are formed on the outer housing 100, and an air intake passage is formed between the air inlet and the air outlet; the heat exchanger 300 and the filter assembly 200 are arranged in the air intake passage.

[0099] The filter assembly 200 is fixed on the inner wall of the air intake passage through the support member 210, and the filter assembly 200 includes a flexible connecting member 220, a folding bracket assembly 230 and a filter element 240.

[0100] The flexible connecting member 220 is detachably connected to the support member 210, and the flexible connecting member 220 at least includes two parallel flexible transverse portions 221.

[0101] The folding bracket assembly 230 includes multiple groups of bracket units 231 arranged along the length direction of the flexible transverse portion 221, and each bracket unit 231 is connected between the two flexible transverse portions 221.

[0102] The filter element 240 is laid above the folding bracket assembly 230 and is used for filtering the passing air flow.

[0103] Wherein, each bracket unit 231 is configured to be deployable along with the flexible transverse portion 221 in the use state, and can be gathered along with the flexible transverse portion 221 in the transportation and storage states.

[0104] That is to say, the diagonal bracing portions 233 in each bracket unit 231 of the folding bracket assembly 230 can rotate at an angle along the bracket transverse portion 232 to realize the deployment and gathering of each bracket unit 231. In addition, the folding bracket assembly 230 can also be deployed and gathered as a whole along with the flexible connecting member 220. When it needs to be installed into the air intake passage, the folding bracket assembly 230 is deployed as a whole to achieve its filtering purpose; when in the transportation and storage states, the folding bracket assembly 230 is in a gathered state, and the overall size is reduced, saving packaging consumables and facilitating transportation and storage.

[0105] The filter assembly 200 can be arranged in the following several ways, or a combination of some of these ways.

[0106] Method 1:

[0107] The flexible connecting member 220 includes two parallel flexible transverse portions 221 which are spaced apart, and the folding bracket assembly 230 is arranged between the two flexible transverse portions 221.

[0108] The folding bracket assembly 230 includes multiple groups of bracket units 231 arranged along the length direction of the flexible transverse portion 221, and the filter element 240 is laid above the folding bracket assembly 230.

[0109] Specifically, the filter element 240 is a filter element, and it can be folded along with the folding bracket assembly 230 and the flexible transverse portion 221.

[0110] Among them, each bracket unit 231 includes a horizontal bracket part 232 and a diagonal bracing part 233. The horizontal bracket part 232 is specifically a crossbar structure, and the cross-sectional shape of the crossbar is circular or other shapes.

[0111] The horizontal bracket part 232 is vertically arranged between two flexible horizontal parts 221.

[0112] Two angled diagonal bracing parts 233 are respectively rotatably connected to both ends of the horizontal bracket part 232, and the bottom of each diagonal bracing part 233 is fixedly connected to the corresponding flexible horizontal part 221 through a suture.

[0113] The diagonal bracing parts 233 located at the same end of the horizontal bracket part 232 can rotate at an angle along the horizontal bracket part 232, and each diagonal bracing part 233 rotates around the corresponding horizontal bracket part 232 as the rotation center to realize the unfolding or gathering of the filtering component 200.

[0114] During the rotation of the diagonal bracing part 233 along the horizontal bracket part 232, the flexible horizontal part 221 connected to its bottom unfolds or gathers accordingly.

[0115] In addition to the folding movement of the diagonal bracing part 233, each bracket unit 231 can also gather together with the flexible horizontal part 221, which is convenient for storage and transportation.

[0116] Method 2:

[0117] Different from Method 1, in this Method 2, the bottom of the diagonal bracing part 233 is hinged to the flexible horizontal part through a fixed horizontal part 234. The fixed horizontal part 234 is fixedly connected to the flexible horizontal part. A first rotating part 2341 is formed on the fixed horizontal part 234, and a second rotating part 2331 is formed at the bottom of each diagonal bracing part 233. Each diagonal bracing part 233 is rotatably connected to the first rotating part 2341 on the corresponding fixed horizontal part 234.

[0118] Method 3,

[0119] On the basis of Method 1 or Method 2, a strengthening part 235 is further arranged between adjacent bracket units 231. Specifically, both ends of the strengthening part 235 are respectively fixed on two flexible horizontal parts 221 and are parallel to the horizontal bracket part 232.

[0120] The filter element 240 is fixed on the horizontal bracket part 232 and the strengthening part 235. Specifically, a plurality of folding parts parallel to the horizontal bracket part 232 are formed on the filter element 240. Each folding part is connected to the corresponding horizontal bracket part 232 and the strengthening part 235, and the filter element 240 folds back and forth between the horizontal bracket part 232 and the strengthening part 235.

[0121] In other words, the filter element 240 covering the surface of the folding bracket assembly 230 is arranged in a continuous W shape under the action of the bracket cross portion 232 and the reinforcement portion 235, so as to increase the filtering area of ​​the filter element 240 and improve the filtering efficiency.

[0122] When the filter assembly 200 is in a folded and gathered state, the filter element 240 is retracted inward along its folded portion to reduce the overall size of the filter assembly 200. When it needs to be assembled into the air inlet channel, the filter element 240, the folding bracket assembly 230 and the flexible connector 220 are simultaneously unfolded.

[0123] The above three methods can be used in combination of method one and method three, or in combination of method two and method three.

[0124] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.
