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.

[0067] In the present application, the air conditioner performs a refrigeration cycle of the air conditioner 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.

[0068] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas 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 the heat is released to the surrounding environment through the condensation process.

[0069] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0070] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0071] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0072] refer to Figure 1 , Fig.11 The present application proposes an air conditioner, which includes an outer shell 10, in which a receiving cavity is formed, and the receiving cavity is used to install working parts such as a heat exchanger 200, a fan assembly 100, and a heat exchange core.

[0073] The heat exchanger 200 is used to exchange heat for the passing airflow, and the fan assembly 100 is used to drive the airflow to flow.

[0074] refer to Figure 2 The fan assembly 100 involved in the present application specifically includes a fan housing 120, a fan 130 and a filter assembly 110. The fan housing 120 is a shell structure as a whole. An air inlet end and an air outlet end are formed at opposite ends of the fan housing 120. Driven by the fan 130, air flow is input from the air inlet end and output from the air outlet end.

[0075] The filter assembly 110 is installed at the air inlet end of the fan housing 120 , and the airflow is filtered by the filter assembly 110 before being input.

[0076] The heat exchanger 200 is disposed at the air outlet end of the fan housing 120 , and the airflow filtered by the filter assembly 110 is finally transported to the heat exchanger 200 for heat exchange.

[0077] The outer shell 10 is provided with an outdoor air inlet, an outdoor air outlet, an indoor air supply outlet and an indoor air return outlet; an air supply passage is formed between the outdoor air inlet and the indoor air supply outlet, and an air exhaust passage is formed between the indoor return air outlet and the outdoor air outlet.

[0078] The fan assembly 100 can be used to transport outdoor airflow as well as indoor airflow, that is, the fan assembly 100 can be installed in an air supply channel or an air exhaust channel.

[0079] Combination Figure 3 , Figure 4 In order to facilitate the maintenance and replacement of the filter assembly 110, the fan 130 and other components during the maintenance and replacement process, the filter assembly 110 involved in the present application is adsorbed on the fan housing 120 through the adsorption member 150.

[0080] The filter assembly 110 can be installed on the fan housing 120 without relying on fasteners such as screws. When the filter assembly 110 needs to be replaced or internal components such as the fan 130 need to be repaired, the filter assembly 110 can be easily and quickly removed, thereby improving the efficiency of repair and replacement.

[0081] In order to ensure the stability of the installation of the filter assembly 110 , the filter assembly 110 is installed on the outside of the air inlet end of the fan housing 120 .

[0082] After the fan 130 is started, the airflow applies inward pressure to the filter assembly 110 when passing through the filter assembly 110, so as to prevent the filter assembly 110 from falling off the adsorbent 150 due to the pressure of the airflow on the filter assembly 110 during the airflow delivery process.

[0083] Below, reference Figure 5-Figure 8 , the specific connection of the adsorption member 150 will be described in detail:

[0084] A connecting inner edge is formed on the air inlet end of the fan housing 120 , and the adsorbents 150 are arranged at intervals on the connecting inner edge.

[0085] The adsorption member 150 is fixed on the inner edge of the connection by gluing, fastening or snapping to achieve adsorption connection with the filter assembly 110 .

[0086] In some embodiments of the present application, inwardly recessed fixing positions may be arranged at intervals on the inner edge of the connection, and the back side of the adsorption member 150 is adhered to the fixing position by adhesive or the like.

[0087] In order to ensure that the surface where the adsorbent 150 is connected to the filter assembly 110 is flush with the inner edge of the connection, the thickness of the adsorbent 150 is selected to match the depth of the fixing position.

[0088] The adsorption member 150 is pasted in the fixed position, and the adsorption surface on the adsorption member 150 is in direct contact with the filter assembly 110 .

[0089] In other embodiments of the present application, the adsorption member 150 may be detachably connected to the inner edge of the connection via fasteners.

[0090] The adsorption member 150 is provided with a connection hole, and inwardly recessed fixing positions may be arranged at intervals on the inner edge of the connection, and fasteners such as bolts pass through the connection hole on the adsorption member 150 and are fixed in the fixing positions.

[0091] Similarly, in order to ensure that the surface of the adsorbent 150 connected to the filter assembly 110 is flush with the inner edge of the connection after being fixed, the thickness of the adsorbent 150 is selected to match the depth of the fixing position.

[0092] In other embodiments of the present application, the adsorption member 150 is detachable on the inner edge of the connection by snapping.

[0093] A through suction port is formed on the inner edge of the connection. The size of the suction port is smaller than the size of the suction piece 150 . The suction piece 150 is connected to the inner side of the inner edge of the connection through the clamping piece 160 .

[0094] That is, the adsorption member 150 is connected to a side away from the filter assembly 110, and contacts the filter assembly 110 through the adsorption port position to achieve the purpose of adsorption connection.

[0095] Specifically, the clamping member 160 is integrally formed with the inner edge of the connection, and the clamping member 160 includes a limiting portion arranged on the peripheral side of the suction port, and a buckle portion 164 is formed on at least one of the limiting portions.

[0096] The limiting portion specifically includes an upper limit 161 disposed above the suction port, a lower limit 162 disposed below the suction port, and side limits 163 disposed on both sides of the suction port.

[0097] The adsorption member 150 is located between the upper limit 161 , the lower limit 162 and the two side limit portions 163 , and the initial connection and fixation of the adsorption member 150 is achieved through each limit portion.

[0098] Furthermore, a buckle portion 164 is formed on at least one of the limiting portions, and the adsorbent 150 is installed between the limiting portions, and the buckle portion 164 is used to fix the adsorbent 150 .

[0099] Specifically, the buckle portion 164 and the limiting portion are both sheet metal structures integrally formed with the inner edge of the connection, that is, the limiting portion is formed by bending the inner edge of the connection inward.

[0100] The buckle portion 164 is integrally formed on the corresponding limiting portion, and a bending portion 165 is formed between the buckle portion 164 and the corresponding limiting portion.

[0101] The bending portion 165 is configured as a connection position between the buckle portion 164 and the corresponding limiting portion, and the size of this position is smaller than the limiting portion and the buckle portion 164, and the bending portion 165 can be bent at an angle.

[0102] In the installed state, the adsorption member 150 is located between the limiting portions, and the bending portion 165 is bent inwardly to snap the buckle portion 164 onto the adsorption portion.

[0103] In order to improve the connection stability of the adsorption member 150 , the buckle portion 164 is disposed on two opposite limiting portions.

[0104] In one embodiment, the snap portions 164 are formed on the upper limit 161 and the lower limit 162, and the adsorbent 150 is installed between the respective limit portions. The snap portions 164 on the upper limit 161 and the lower limit 162 are bent downward and upward respectively to contact the adsorbent 150, thereby limiting the adsorbent 150 on the respective limit portions to limit the displacement of the adsorbent 150 in all directions.

[0105] refer to Figure 5 In some other embodiments of the present application, the fan housing 120 is formed as a whole by sheet metal, and the fan housing 120 includes an upper shell and a lower shell. After the upper shell and the lower shell are formed by sheet metal respectively, the connection points are fixed by welding or mechanical connection.

[0106] Specifically, the upper shell includes a top wall 121 and side walls 125 integrally formed on both sides of the top wall 121 , and the lower shell includes a bottom wall 122 .

[0107] Upward flanges are formed on both sides of the lower shell for connecting with the two side walls 125 of the upper shell.

[0108] The connecting inner edge includes a connecting upper edge 123 formed on the top wall 121 and bent downward, two connecting side edges 126 formed on the two side walls 125 and bent toward each other, and a connecting lower edge 124 formed on the front side of the bottom wall 122 and bent upward.

[0109] The buckle portion 164 is formed at least on the oppositely disposed upper connection edge 123 and the oppositely disposed lower connection edge 124 , or the buckle portion 164 is formed on two oppositely disposed side connection edges 126 .

[0110] Since the formation of the buckle portion 164 requires a certain space, and in order to reduce the size of the inner edge of the connection as much as possible to reduce wind resistance, the width of the inner edge of the connection where the buckle portion 164 is located is designed to be greater than the width of other positions.

[0111] That is, when the buckle portion 164 is formed on the upper connection edge 123 and the lower connection edge 124 , the width of the upper connection edge 123 and the lower connection edge 124 is greater than the width of the two side connection edges 126 .

[0112] When the buckle portions 164 are formed on the two connecting side edges 126 , the widths of the two connecting side edges 126 are greater than the widths of the connecting upper edge 123 and the connecting lower edge 124 .

[0113] refer to Figure 4 , Fig. 9 , Fig.10 In some other embodiments of the present application, a positioning frame 140 is detachably connected to the inner edge of the connection. The positioning frame 140 is a frame structure as a whole, and is configured to be arranged on the peripheral side of the filter assembly 110.

[0114] That is, the filter assembly 110 is disposed on the inner side of the positioning frame 140 , and the positioning frame 140 plays a further limiting role in the positioning and connection of the filter assembly 110 .

[0115] The positioning frame 140 is formed of sheet metal as a whole, and includes two horizontal frames 141 and a vertical frame 142 vertically arranged between the two horizontal frames 141 .

[0116] The cross beams and longitudinal beams are formed separately and then connected together to form a U-shaped frame structure.

[0117] A positioning flange is formed on the inner circumference of the positioning frame 140 . Specifically, a transverse flange 1411 and a longitudinal flange 1422 are formed on the transverse beam and the longitudinal beam, respectively. The transverse flange 1411 and the longitudinal flange 1422 are bends formed on the transverse beam and the longitudinal beam, respectively.

[0118] A positioning flange is formed on the peripheral side of the filter element 110 , the height of the positioning flange is adapted to the thickness of the filter assembly 110 , and the adsorbent 150 is located on the inner side of the positioning flange.

[0119] In the installed state, the outer surface of the filter assembly 110 is flush with the end of the positioning flange.

[0120] Fixed ends 1421 are formed at both ends of the longitudinal frame 142 , and the fixed ends 1421 are detachably connected to the transverse frame 141 .

[0121] A second connection hole 1423 is formed on the fixed end portion 1421 , and first connection holes 1412 are provided at both ends of the horizontal frame 141 . Fasteners such as bolts pass through the corresponding first connection holes 1412 and second connection holes 1423 to connect and fix the horizontal frame 141 and the vertical frame 142 .

[0122] The fixed end portion 1421 is formed with a profile at a middle position compared to the longitudinal frame 142 , and the thickness of the profile matches the thickness of the transverse frame 141 , so that the transverse frame 141 and the longitudinal frame 142 are both in contact with the inner edge of the connection when in the connected state.

[0123] Avoid forming a gap between the horizontal frame 141 or the vertical frame 142 and the inner edge of the connection due to the height difference between the horizontal frame 141 and the vertical frame 142, avoid air flow from the air input, and reduce the filtering effect.

[0124] The number of the filter components 110 is at least one group. To facilitate installation and manufacturing, the number of the filter components 110 can also be multiple, and the multiple filter components 110 are sequentially connected to the air inlet end.

[0125] Correspondingly, each filter assembly 110 is provided with at least one clamping portion at the top and the bottom, and each filter assembly 110 is connected to the fan housing 120 by adsorption.

[0126] Each filter assembly 110 includes a filter outer frame 111 and a filter portion 112 formed in the filter outer frame 111 . The filter outer frame 111 is made of a metal that can be adsorbed by the adsorption portion, or a connection portion 113 that can be adsorbed by the adsorption portion is connected to a corresponding position of the filter outer frame 111 .

[0127] The filter unit 112 is specifically a filter mesh and other filter materials such as activated carbon adsorption, which are used to filter the passing airflow.

[0128] The material of the adsorption member 150 is a magnet, and the magnet is a permanent magnet or an electromagnet.

[0129] The material of the filter outer frame 111 or the connecting portion 113 is specifically a material that is easily attracted by a magnet, such as iron.

[0130] The air outlet end arranged opposite to the air inlet end of the fan housing 120 is connected to the heat exchanger 200. Driven by the fan 130, the air flow is input from the air inlet end of the fan housing 120 through the filter component 110, and then output from the output end of the fan housing 120 to the heat exchanger 200.

[0131] The installation inner cavity is surrounded by an upper cover plate, a lower cover plate 11 and a peripheral side plate located between the upper cover plate and the lower cover plate 11.

[0132] A connecting edge recessed toward the inner cavity is formed on the inspection opening, and the inspection cover plate 12 is detachably connected to the connecting edge by fasteners. The connecting edge is formed on at least two opposite edges of the inspection opening.

[0133] A sealing layer is formed on the connecting edge. In the installed state, the outer surface of the lower cover plate 11 is flush with the outer surface of the inspection cover plate 12 .

[0134] The inner cavity of the outer shell 10 is provided with working parts such as a heat exchanger 200 and a compressor.

[0137] The outer shell 10 is usually made of sheet metal material. The outer shell 10 is a flat rectangular structure as a whole. During installation and use, it can be hung on the ceiling of the user's home for use.

[0138] When installed, the inspection port faces downward, making it convenient for operators to inspect.

[0139] To facilitate processing and installation, the inspection port and the inspection cover 12 are both square structures, and the two opposite edges of the inspection port are provided with connecting edges recessed toward the installation inner cavity, which are used to directly overlap the inspection cover 12 and are fixed by fasteners.

[0140] Through holes are provided at corresponding positions of the connecting edge and the inspection cover plate 12, and the inspection cover plate 12 is detachably connected to the connecting edge by fasteners.

[0141] The connecting edge is formed at least on two opposite edges of the inspection port, and the connecting edge is integrally formed with the lower cover plate 11. In the installed state, the outer surface of the lower cover plate 11 is flush with the outer surface of the inspection cover plate 12, ensuring that the surface of the fresh air air conditioner is smooth and beautiful.

[0142] Of course, the inspection opening and the inspection cover 12 may also be in other shapes and are not limited to the square shape mentioned above.

[0143] Since operators need to perform maintenance from the inspection port, in order to avoid scratches on the operators by the sharp inner edge around the inspection port, an upwardly extending flange is provided on the edge of the inspection port, and a protective layer is provided on the flange.

[0144] The material of the protective layer is a rubber layer (EPDM layer, etc.) or a flannel layer.

[0145] The two side edges of the inspection cover 12 corresponding to the flange are respectively formed with cover curling edges extending toward the installation inner cavity. In order to prevent the cover curling from damaging the protective layer on the flange during the installation of the inspection cover 12, the end of each cover curling edge is formed with a relatively extended bend, which is flipped inward. Therefore, during the installation of the inspection cover 12, the smooth transition position on the cover curling edge contacts the protective layer, thereby preventing the protective layer from being damaged during the installation of the inspection cover 12.

[0146] The present application also proposes an air conditioner, including an outer shell 10, wherein an accommodating cavity is formed in the outer shell 10, and the accommodating cavity is used to install working components such as a heat exchanger 200, a fan assembly 100, and a heat exchange core.

[0147] The fan assembly 100 can be used to transport outdoor airflow as well as indoor airflow, that is, the fan assembly 100 can be installed in an air supply channel or an air exhaust channel.

[0148] In order to facilitate the maintenance and replacement of the filter assembly 110, the fan 130 and other components during the maintenance and replacement process, the filter assembly 110 is configured to be detachably connected to the fan housing 120 by adsorption.

[0149] In some other embodiments of the present application, the adsorption member 150 is a ring-shaped adsorption belt formed at the air inlet end of the fan housing 120 .

[0150] The adsorption belt can be an electromagnetic adsorption belt, which is externally connected to a power line. When the power is turned on, the adsorption member 150 is charged to adsorb the filter component 110.

[0151] When the power is disconnected, the suction force of the adsorbent 150 disappears, and the filter assembly 110 is removed from the fan housing 120.

[0152] In some other embodiments of the present application, penetrating adsorption openings are formed on the inner edge of the connection, and a magnet is installed on each adsorption opening respectively.

[0153] The size of the adsorption port is smaller than that of the adsorption component 150, and the adsorption component 150 is connected to the inner side of the inner edge of the connection through the snap-fit ​​component 160, that is, the adsorption component 150 is connected to the side away from the filter assembly 110, and contacts the filter assembly 110 through the position of the adsorption port to achieve the purpose of adsorption connection.

[0154] The clamping member 160 includes a limiting portion disposed around the suction port, and a buckle portion 164 is formed on at least one of the limiting portions.

[0155] A buckle portion 164 is formed on at least one of the limiting portions, and the adsorbent 150 is installed between the limiting portions, and the buckle portion 164 is used to fix the adsorbent 150 .

[0156] Specifically, the buckle portion 164 and the limiting portion are both sheet metal structures integrally formed with the inner edge of the connection, that is, the limiting portion is formed by bending the inner edge of the connection inward.

[0157] The snap portion 164 is integrally formed on the corresponding limiting portion, and a bending portion 165 is formed between the snap portion 164 and the corresponding limiting portion. The bending portion 165 is configured as a connecting position between the snap portion 164 and the corresponding limiting portion, and the size of this position is smaller than that of the limiting portion and the snap portion 164, and the bending portion 165 can be bent at an angle.

[0158] In the installed state, the adsorption member 150 is located between the limiting portions, and the bending portion 165 is bent inwardly to snap the buckle portion 164 onto the adsorption portion.

[0159] In order to improve the connection stability of the adsorption member 150 , the buckle portion 164 is disposed on two opposite limiting portions.

[0160] The air conditioner involved in the present application has a fan assembly 100 for driving air flow, which is detachably connected to a filter assembly 110 through an adsorbent 150. The filter assembly 110 can filter the air flow passing through, reduce dust and even bacteria in the air flow, and is beneficial to improving environmental health;

[0161] When the filter assembly 110 needs to be cleaned or replaced, or other components in the fan assembly 100 need to be repaired or replaced, the filter assembly 110 can be easily and quickly removed from the fan housing 120, thereby improving the assembly and disassembly efficiency in a limited operating space and reducing the difficulty of repair and cleaning.

[0162] 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.

[0163] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
