In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0050] Next, with reference to the drawings, the air inlet frame assembly 100 according to the first aspect of the present application is described. The air inlet frame assembly 100 can be used in a supply air device, and in the following description of the present application, the air inlet frame assembly 100 is used in an air conditioner 200 as an example. Those skilled in the art can easily understand the implementation of the air inlet frame assembly 100 in other types of supply air devices after reading the following scheme.

[0051] As shown in Figures 1-4 and Figure 10 The air inlet frame assembly 100 includes an air inlet frame 1, and the air inlet frame 1 forms a first air inlet 1a on both sides in a first direction, so that both sides of the air inlet frame 1 in the first direction can realize air inlet, which is beneficial to improve the air inlet range of the air inlet frame 1 and facilitate better meet the air supply demand of the air conditioner 200. Exemplarily, the first direction is the left-right direction, so that both sides of the air inlet frame 1 can realize air inlet, and the air inlet frame assembly 100 can better adapt to the air inlet demand of the air conditioner cabinet. The air inlet frame 1 can include a first plate body 11 and a second plate body 12, and the left and right sides of the first plate body 11 are respectively connected with the second plate body 12. Each second plate body 12 forms a first air inlet 1a thereon.

[0052] As shown in Figure 10As shown, the air inlet frame assembly 100 further comprises a first filter structure 2 arranged at the first air inlet 1a, so that the first filter structure 2 can filter the airflow flowing from the first air inlet 1a into the air inlet frame 1, thereby improving the quality of the air entering the air inlet frame 1 from the first air inlet 1a. The first air inlet 1a has a slot 1c formed on one side edge in the second direction, and at least one of the two side edges of the first air inlet 1a in the third direction and the other side edge of the first air inlet 1a in the second direction has a buckle 1d. The first filter structure 2 has a plug 2a and an elastic buckle 2b, the plug 2a is inserted into the slot 1c along the second direction, and the elastic buckle 2b is buckled to the buckle 1d. The first direction, the second direction and the third direction are perpendicular to each other.

[0053] Therefore, the elastic deformation capability of the elastic buckle 2b can be used to facilitate the disassembly and assembly of the first filter structure 2, improve the disassembly and assembly efficiency of the air inlet frame assembly 100, and facilitate the replacement and cleaning of the first filter structure 2, thereby improving the maintenance convenience of the air inlet frame assembly 100. During the installation of the first filter structure 2, the plug 2a can be inserted into the slot 1c first, and then the first filter structure 2 is close to the air inlet frame 1. The elastic buckle 2b is deformed by being pressed, and after the first filter structure 2 is installed in place, the elastic buckle 2b is restored to the initial state to abut against the buckle 1d, so that the elastic buckle 2b is buckled to the buckle 1d, thereby improving the installation convenience and speed of the first filter structure 2. At the same time, during the disassembly of the first filter structure 2, the first filter structure 2 moves away from the air inlet frame 1, the elastic buckle 2b is deformed by being pressed to separate from the buckle 1d, and then the plug 2a is separated from the slot 1c, so that the first filter structure 2 is removed from the air inlet frame 1

[0054] In addition, the plug 2a and the elastic buckle 2b are arranged to facilitate the positioning of the first filter structure 2 in the first direction and the third direction by the cooperation of the plug 2a and the slot 1c, and facilitate the positioning of the first filter structure 2 in the first direction by the cooperation of the elastic buckle 2b and the buckle 1d, thereby achieving reliable installation of the first filter structure 2 and simple installation structure. Obviously, even if the first air inlet 1a of the embodiment of the present application is multiple, and the first filter structure 2 is multiple, since the first filter structure 2 is convenient to disassemble and assemble, the maintenance of the air inlet frame assembly 100 is also facilitated.

[0055] Exemplarily, the second direction is the up-down direction, the third direction is the front-back direction, the slot 1c can be formed at the lower side edge of the first air inlet 1a, at least one of the front side edge, the rear side edge and the upper side edge of the first air inlet 1a has the buckle position 1d, and then the latch 2a can be located at the lower end of the first filter structure 2; when the first filter structure 2 is installed, the latch 2a can be inserted into the slot 1c from top to bottom, and then the upper end of the first filter structure 2 is close to the air inlet frame 1, so that the elastic buckle 2b is buckled in place, at this time, the latch 2a and the slot 1c are not easy to separate under the action of gravity of the first filter structure 2. Of course, in other examples, the slot 1c can also be formed at the upper side edge of the first air inlet 1a.

[0056] It can be understood that, in the embodiments of the present application, for a single first air inlet 1a, the slot 1c can be one or more, and the buckle position 1d can be one or more.

[0057] According to the air inlet frame assembly 100 provided in the embodiments of the present application, the latch 2a and the elastic buckle 2b are arranged to realize convenient disassembly and assembly of the first filter structure 2 by the limiting capacity of the latch 2a and the elastic deformation capacity of the elastic buckle 2b, improve the disassembly and assembly efficiency of the air inlet frame assembly 100, and facilitate replacement, cleaning and the like of the first filter structure 2, and improve the maintenance convenience of the air inlet frame assembly 100; even if the first filter structure 2 is multiple, the air inlet frame assembly 100 can also be quickly disassembled and assembled.

[0058] In some embodiments, as shown in Figure 3 , Figure 5 and Figure 9 , the elastic buckle 2b includes an elastic arm 2c and a clamping protrusion 2d, the clamping protrusion 2d is arranged at the free end 2e of the elastic arm 2c, and the free end 2e of the elastic arm 2c can be understood as an end of the elastic arm 2c which is not fixed or not restricted, so as to fully utilize the elastic deformation capacity of the elastic arm 2c to adjust the position of the clamping protrusion 2d, and realize cooperation or separation of the clamping protrusion 2d and the buckle position 1d. The clamping protrusion 2d is arranged on the side of the elastic arm 2c away from the center of the first air inlet 1a, so as to better cooperate or separate the elastic buckle 2b and the buckle position 1d located at the edge of the first air inlet 1a.

[0059] In the embodiments of the present application, the structure of the clamping protrusion 2d is not specifically limited, for example, the cross-sectional shape of the clamping protrusion 2d is semicircular, which is beneficial to improve the disassembly and assembly smoothness of the first filter structure 2; of course, the cross-sectional shape of the clamping protrusion 2d can also be polygonal, for example, triangular.

[0060] In some embodiments, as shown in Figure 9As shown, the elastic arm 2c has a fixed end 2f and a free end 2e, and the elastic arm 2c comprises a first elastic piece 2g and two second elastic pieces 2h respectively arranged on two sides of the first elastic piece 2g in the second direction, the first elastic piece 2g is connected with each second elastic piece 2h at the fixed end 2f, and the first elastic piece 2g and each second elastic piece 2h are spaced apart at the free end 2e to define a gap 2i, the clamping protrusion 2d is arranged on the first elastic piece 2g, and the clamping protrusion 2d is buckled on the buckling position 1d.

[0061] It can be understood that the fixed end 2f of the elastic arm 2c can be understood as an end of the elastic arm 2c fixedly connected with other parts on the first filter structure 2. Since the first elastic piece 2g and each second elastic piece 2h are connected at the fixed end 2f, the first elastic piece 2g and the second elastic piece 2h are both constrained at the fixed end 2f of the elastic arm 2c, which is conducive to improving the setting reliability of the elastic arm 2c, and the two second elastic pieces 2h are respectively arranged on opposite sides of the first elastic piece 2g, which is conducive to making the elastic arm 2c substantially present a sheet structure, so that the elastic arm 2c has good bending deformation capability and can also consider a certain bending stiffness, and in combination with the first elastic piece 2g and the second elastic piece 2h being spaced apart at the free end 2e, the second elastic piece 2h does not constrain one end of the first elastic piece 2g corresponding to the free end 2e, and the clamping protrusion 2d is arranged at the one end of the first elastic piece 2g corresponding to the free end 2e, so that the setting of the second elastic piece 2h can appropriately provide the bending stiffness of the first elastic piece 2g to a certain extent, while not excessively increasing, and the first elastic piece 2g still has a certain bending deformation capability, thereby being conducive to improving the reliability of the elastic arm 2c.

[0062] Of course, the structure of the elastic arm 2c is not limited to this; for example, in other embodiments of the present application, the elastic arm 2c comprises a third elastic part and a fourth elastic part, the third elastic part is arranged on the inner surface of the first filter structure 2 and extends inwardly to be connected with the fourth elastic part, the fourth elastic part extends outwardly from the third elastic part, so that the elastic arm 2c is substantially in a U shape, and the clamping protrusion 2d is arranged on the side surface of the fourth elastic part away from the third elastic part, and the cooperation and separation of the clamping protrusion 2d and the buckling position 1d can also be achieved.

[0063] In some embodiments, as shown in the drawings, Figure 5 As shown, the air inlet frame 1 is formed with a first mounting groove 1e with a slot opening outwardly, so that the slot opening of the first mounting groove 1e is arranged towards the outer side of the air inlet frame 1, the first air inlet 1a is formed on the groove bottom wall 1f of the first mounting groove 1e, and the first filter structure 2 is fitted in the first mounting groove 1e, so that the groove wall of the first mounting groove 1e can to a certain extent play a good limiting role on the first filter structure 2, and is conducive to reducing the height of the first filter structure 2 protruding from the outer surface of the air inlet frame 1.

[0064] The first filtering structure 2 is adapted to abut against the groove bottom wall 1f of the first mounting groove 1e, for example, the flange 211 described below is adapted to abut against the groove bottom wall 1f of the first mounting groove 1e. During installation of the first filtering structure 2, the groove bottom wall 1f of the first mounting groove 1e can limit the first filtering structure 2, so that the operator can know in time that the first filtering structure 2 has been installed in place. At the same time, the buckle position 1d protrudes inward from the groove bottom wall 1f of the first mounting groove 1e, and the side of the buckle position 1d away from the first mounting groove 1e abuts against the clamping protrusion 2d of the elastic buckle 2b. When the groove bottom wall 1f of the first mounting groove 1e abuts against the first filtering structure 2, the abutting force exerted by the groove bottom wall 1f of the first mounting groove 1e on the first filtering structure 2 is the first force. When the buckle position 1d abuts against the elastic buckle 2b, the abutting force exerted by the buckle position 1d on the first filtering structure 2 is the second force. The directions of the first force and the second force are basically opposite, so that the first filtering structure 2 is clamped, which is beneficial to further improve the installation reliability of the first filtering structure 2. At the same time, the buckle position 1d has a simple structure.

[0065] In addition, the groove bottom wall 1f of the first mounting groove 1e can be understood as the side wall of the first mounting groove 1e opposite to the groove opening thereof. For example, the air inlet frame 1 includes the first plate body 11 and the second plate body 12, and the left and right sides of the first plate body 11 are respectively bent and connected with the second plate body 12. Each second plate body 12 is formed with the first mounting groove 1e. The groove opening of the first mounting groove 1e on the left side second plate body 12 can be arranged to face left, and the groove bottom wall 1f of the first mounting groove 1e can be the right side wall thereof. The groove opening of the first mounting groove 1e on the right side second plate body 12 can be arranged to face right, and the groove bottom wall 1f of the first mounting groove 1e can be the left side wall thereof.

[0066] In some embodiments, as shown in Figure 5 The outer surface of the first filtering structure 2 is flush with the outer surface of the air inlet frame 1, for example, the outer surface of the first filtering structure 2 can be in the same plane or on the same curved surface as the outer surface of the air inlet frame 1. In this way, the air inlet frame assembly 100 is not easy to cause bumps to the first filtering structure 2 during assembly, transportation, use and the like, and is also beneficial to improve the structural integrity of the air inlet frame assembly 100.

[0067] For example, as shown in Figure 5 The air inlet frame 1 includes the first plate body 11 and the second plate body 12, and each second plate body 12 is formed with the first air inlet 1a. The outer surface of the first filtering structure 2 is flush with the outer surface of the corresponding second plate body 12.

[0068] In some embodiments, as shown in Figures 8-10As shown, the first filter structure 2 comprises a bracket 21 and a filter screen 22, the filter screen 22 is arranged on the bracket 21, the latch 2a and the elastic buckle 2b are both formed on the outer peripheral side of the bracket 21, the outer peripheral side of the bracket 21 has a flange 211, the flange 211 can be formed as an open ring or a closed ring, and the flange 211 is beneficial to improve the structural stability of the bracket 21; part of the flange 211 is recessed towards the center of the first air inlet 1a to form a groove 211a, the groove 211a can be formed by part of the flange 211 being recessed towards the center of the first air inlet 1a along the radial direction of the flange 211, the groove 211a is open on one side corresponding to the free end 2e of the flange 211, and the fixed end 2f of the elastic buckle 2b is connected to the open side of the groove 211a, so that the fixed end 2f of the elastic buckle 2b is connected to the part of the flange 211 corresponding to the groove 211a.

[0069] It can be seen that the groove 211a can improve the structural strength and bending strength of the flange 211 to a certain extent, so that the flange 211 is not easy to bend due to installation external force when the first filter structure 2 is installed, and the position of the elastic buckle 2b is relatively close to the center of the first air inlet 1a relative to the outer edge of the bracket 21 due to the arrangement of the groove 211a, and the buckle position 1d is located at the edge position of the first air inlet 1a, so that the position of the elastic buckle 2b and the position of the buckle position 1d are well matched to realize reliable cooperation between the two.

[0070] It should be noted that the "open ring" described herein refers to a ring with an opening (i.e., not a closed ring), wherein "ring" is understood in a broad sense, i.e., not limited to "circular ring", for example, it can also be "polygonal ring" and the like.

[0071] In some embodiments, as shown in Figure 3 , Figure 5 and Figure 9 , the first filter structure 2 comprises a bracket 21 and a filter screen 22, the latch 2a and the elastic buckle 2b are both formed on the outer peripheral side of the bracket 21, the outer peripheral side of the bracket 21 has a flange 211, part of the flange 211 is recessed towards the center of the first air inlet 1a to form a groove 211a, the groove 211a is open on one side corresponding to the free end 2e of the flange 211, and the fixed end 2f of the elastic buckle 2b is connected to the open side of the groove 211a; at this time, the elastic buckle 2b comprises an elastic arm 2c and a clamping protrusion 2d, the clamping protrusion 2d is arranged at the free end 2e of the elastic arm 2c, and the clamping protrusion 2d is protruding on the side of the elastic arm 2c away from the center of the first air inlet 1a.

[0072] As shown in Figure 9As shown, the elastic arm 2c has a fixed end 2f and a free end 2e, and the elastic arm 2c comprises a first elastic sheet part 2g and two second elastic sheet parts 2h respectively arranged on two sides of the first elastic sheet part 2g in the second direction, the first elastic sheet part 2g is connected with each second elastic sheet part 2h at the fixed end 2f, and the first elastic sheet part 2g and each second elastic sheet part 2h are spaced apart at the free end 2e to define a gap 2i, the clamping protrusion 2d is arranged on the first elastic sheet part 2g, and the clamping protrusion 2d is buckled on the buckle position 1d.

[0073] The fixed end 2f of the elastic buckle 2b (which can also be understood as the fixed end 2f of the elastic arm 2c) is connected to the turned edge 211, facilitating the arrangement of the elastic buckle 2b, for example, the elastic buckle 2b can be integrally formed on the turned edge 211; at the same time, the elastic buckle 2b can take into account a certain bending stiffness and bending deformation ability, which is beneficial to improve the reliability of the elastic arm 2c.

Thus, when the first filter structure 2 is installed, the groove bottom wall 1f of the first mounting groove 1e serves as a certain limiting effect on the first filter structure 2, so as to provide the operator with the first filter structure 2 installed in place, and when the groove bottom wall 1f of the first mounting groove 1e abuts against the first filter structure 2, the abutting force exerted by the groove bottom wall 1f of the first mounting groove 1e on the first filter structure 2 is the first force, and when the buckle position 1d abuts against the elastic buckle 2b, the abutting force exerted by the buckle position 1d on the first filter structure 2 is the second force, the directions of the first force and the second force are basically opposite, realizing the clamping arrangement of the first filter structure 2, which is beneficial to further improve the installation reliability of the first filter structure 2.

[0075] In some embodiments, as shown in Figure 4 , Figure 7 , Figure 8 and Figure 10 As shown, the first filter structure 2 is formed with a buckle slot 21a recessed inwardly into the air inlet frame 1 at one end thereof away from the plug 2a in the second direction, and the edge of the slot opening of the buckle slot 21a has a buckle edge 21b extending toward the center of the slot opening. Thus, when the first filter structure 2 is disassembled, the user can put his hand into the buckle slot 21a and buckle it on the inner side of the buckle edge 21b, exert an outward force on the first filter structure 2 to separate the elastic buckle 2b from the buckle position 1d, and then move the first filter structure 2 in the first direction to separate the plug 2a from the plug slot 1c, so as to complete the disassembly of the first filter structure 2, which is convenient to operate.

[0076] Obviously, the arrangement of the handgrip groove 21a and the handgrip edge 21b enables the first filter structure 2 to provide a force application position during disassembly, thereby improving the disassembly convenience. Exemplarily, the second direction is the up-down direction, the latch 2a is located at the lower end of the first filter structure 2, the handgrip groove 21a is located at the upper end of the first filter structure 2, and the handgrip edge 21b can be located at the top end edge, the bottom end edge, the front end edge or the rear end edge of the slot of the handgrip groove 21a, for example, the handgrip edge 21b can extend downward from the top end edge of the slot of the handgrip groove 21a.

[0077] In some embodiments, as shown in Figure 4 , Figure 7 and Figure 10 , the air inlet frame assembly 100 further comprises a first air inlet grille 3, the first air inlet grille 3 is arranged at the first air inlet 1a, and the insertion slot 1c and the latching position 1d are both located at the outer peripheral side of the first air inlet grille 3, so that the first air inlet grille 3 can prevent external objects from impacting the parts inside the air inlet frame 1, prevent users or sundries from reaching into the inside of the air inlet frame 1 through the first air inlet 1a, and improve the structural strength and stability of the air inlet frame 1, while ensuring the free flow of air at the first air inlet 1a. The first air inlet grille 3 is integrally formed with the air inlet frame 1, which can save the assembly process of the first air inlet grille 3 and the air inlet frame 1, and does not need to process a connecting structure on the first air inlet grille 3 and the air inlet frame 1, which is conducive to simplifying the structure and improving the assembly efficiency; in addition, the first air inlet grille 3 and the first filter structure 2 can be cooperatively matched to improve the air quality entering the air inlet frame 1.

[0078] Further, as shown in Figure 4 and Figure 5 , the first air inlet grille 3 is located at the inner side of the first filter structure 2, so that in the air flow direction at the first air inlet 1a, the first air inlet grille 3 is located at the downstream side of the first filter structure 2, and the air flow at the first air inlet 1a first flows through the first filter structure 2 and then flows through the first air inlet grille 3, so that the first air inlet grille 3 is less likely to affect the disassembly of the first filter structure 2, and the disassembly process of the first filter structure 2 can be implemented on the outer side of the first air inlet grille 3, thereby facilitating a larger disassembly operation space.

[0079] Optionally, as shown in Figure 4 and Figure 10As shown, the first air inlet grille 3 can include a plurality of first ribs 31 arranged along the second direction, the support 21 of the first filter structure 2 can include a plurality of second ribs 212 arranged along the second direction, the first ribs 31 and the second ribs 212 respectively extend along the third direction, each first rib 31 can correspond to a second rib 212, and the normal projection of at least one first rib 31 is located within the normal projection range of the corresponding second rib 212 along the normal direction of the first air inlet 1a, so that the first rib 31 will not directly face the wind to cause wind resistance, which is beneficial to reduce the air inlet resistance of the air inlet frame assembly 100 and improve the air inlet smoothness.

[0080] In some embodiments, as shown, Figure 10 The air inlet frame 1 is an integrally formed member. In this way, the structural strength and reliability of the air inlet frame 1 can be improved, and the assembly process can be saved. For example, the air inlet frame 1 is a plastic member.

[0081] Exemplarily, the air inlet frame assembly 100 is used in the air conditioner 200, the air inlet frame 1 participates in defining the appearance surface of the air conditioner 200, and the air inlet frame 1 is an integrally formed member, so that the air inlet frame 1 not only can play its original role, but also can be used as the air inlet panel and the air inlet frame of the air conditioner 200, which is convenient for "one thing with multiple uses", simplifies the assembly of the air conditioner 200, and improves the production efficiency.

[0082] In some embodiments, as shown, Figure 16 The air inlet frame 1 is formed with a second mounting groove 1g on one side in the second direction, and the groove bottom wall 1f of the second mounting groove 1g is formed with a second air inlet 1b, so that the air inlet frame 1 can realize three-side air inlet, so as to further improve the air inlet area of the air inlet frame 1; the air inlet frame assembly 100 further includes a second filter structure 4, and the second filter structure 4 is arranged at the second air inlet 1b, so that the second filter structure 4 can filter the airflow flowing into the air inlet frame 1 from the second air inlet 1b, which is beneficial to improve the quality of the air entering the air inlet frame 1 from the second air inlet 1b. The second filter structure 4 is detachably arranged, which is convenient for replacement, cleaning and the like of the second filter structure 4, and facilitates the maintenance of the air inlet frame assembly 100.

[0083] Optionally, the second filter structure 4 is interference-fitted in the second mounting groove 1g, so as to facilitate the disassembly and assembly of the second filter structure 4 on the premise of realizing the detachable arrangement of the second filter structure 4, and simplify the disassembly and assembly structure design of the second filter structure 4.

[0084] Exemplarily, the air inlet frame 1 includes a first plate body 11, a second plate body 12, and a third plate body connected between the second plate body 12 and connected with the first plate body 11 at one end in the second direction, and the second air inlet 1b is formed on the third plate body.

[0085] In some embodiments, as shown,Figure 16 As shown in the drawings, the air inlet frame assembly 100 further comprises a second air inlet grille 5 arranged at the second air inlet 1b, so that the second air inlet grille 5 can prevent external objects from impacting the parts inside the air inlet frame 1, and can prevent users or sundries from extending into the air inlet frame 1 through the second air inlet 1b, and can also improve the structural strength and stability of the air inlet frame 1, while ensuring the free flow of air at the second air inlet 1b. The second air inlet grille 5 is integrally formed with the air inlet frame 1, which can save the assembly process of the second air inlet grille 5 and the air inlet frame 1, and does not need to process a connecting structure on the second air inlet grille 5 and the air inlet frame 1, which is beneficial to simplify the structure and improve the assembly efficiency; in addition, the second air inlet grille 5 and the second filter structure 4 can be cooperated to improve the air quality entering the air inlet frame 1.

[0086] Further, as shown in the drawings, Figure 16 The second air inlet grille 5 is located on the inner side of the second filter structure 4, so that in the air flow direction at the second air inlet 1b, the second air inlet grille 5 is located on the downstream side of the second filter structure 4, and the air flow at the second air inlet 1b first flows through the second filter structure 4 and then flows through the second air inlet grille 5, so that the second air inlet grille 5 is not easy to affect the disassembly of the second filter structure 4, and the disassembly process of the second filter structure 4 can be realized on the outer side of the second air inlet grille 5, which is convenient for having a larger disassembly operation space.

[0087] According to the air conditioner 200 of the second aspect of the present application, the air inlet frame assembly 100 according to the first aspect of the present application is used, and the air inlet frame 1 participates in defining the appearance surface of the air conditioner 200, so that the air inlet frame 1 can be used as the air inlet panel and the air inlet frame of the air conditioner 200.

[0088] Exemplarily, the air inlet frame 1 comprises a first plate body 11 and a second plate body 12, the left and right sides of the first plate body 11 are respectively connected with the second plate body 12 by bending, and the first plate body 11 and the second plate body 12 both participate in defining the appearance surface of the air conditioner 200.

[0089] According to the air conditioner 200 of the embodiment of the present application, the air inlet frame assembly 100 is used, which is convenient for the maintenance of the air conditioner 200.

[0090] It is worth noting that the type of the air conditioner 200 according to the embodiment of the present application is not limited, and can be an all-in-one air conditioner or a split air conditioner, the all-in-one air conditioner can include a window air conditioner or a mobile air conditioner, and the split air conditioner can include an air conditioner hanging machine or an air conditioner cabinet machine. When the type of the air conditioner 200 is determined, the shape of the air inlet frame 1 can be adaptively designed.

[0091] In the following description of this application, air conditioner 200 is used as an example of a cabinet air conditioner. Those skilled in the art will readily understand after reading the following description that air conditioner 200 can be used for other types of implementations.

[0092] In some embodiments, such as Figures 11-17 As shown, the second direction is the up-down direction, the first direction is the left-right direction, and the third direction is the front-back direction. The air conditioner 200 also includes an air outlet frame 101, which is located above the air inlet frame 1. A first air outlet 101a is formed on the front side of the air outlet frame 101, and second air outlets 101b are formed on the left and right sides of the air outlet frame 101, respectively. This facilitates multi-sided air outlets of the air conditioner 200, which helps to improve the air supply range. Moreover, the air conditioner 200 can achieve air outlets from the front and both sides to achieve wraparound air supply. For example, when the air conditioner 200 is a cabinet air conditioner, it can improve the problem that users on the left and right sides cannot feel the cooling or heating effect, especially under low and medium operating conditions, so that the air conditioner 200 can better adapt to home scenarios, especially home entertaining scenarios, and improve comfort.

[0093] like Figure 17 and Figure 18 As shown, the air conditioner 200 also includes a first air guide structure 102 and a second air guide structure 103. The first air guide structure 102 is located at the first air outlet 101a, and the second air guide structure 103 is rotatably located at the second air outlet 101b. It can be seen that the first air guide structure 102 can move relative to the air outlet frame 101 to open and close the first air outlet 101a and / or change the air outlet direction of the first air outlet 101a. The second air guide structure 103 can move relative to the air outlet frame 101 to open and close the second air outlet 101b and / or change the air outlet direction of the second air outlet 101b.

[0094] The first air guiding structure 102 includes a first air guiding plate 1021 and a second air guiding plate 1022 spaced apart along the airflow direction at the first air outlet 101a. The rotation axis of the first air guiding plate 1021 and the rotation axis of the second air guiding plate 1022 form a non-zero angle, so the extension directions of the first air guiding plate 1021 and the second air guiding plate 1022 are different. The first air guiding plate 1021 and the second air guiding plate 1022 can rotate relative to the air outlet frame 101 respectively so that they cooperate to adjust the air outlet direction of the first air outlet 101a, which is beneficial to increase the air outlet angle range of the first air outlet 101a and facilitates further increasing the air supply range of the air conditioner 200.

[0095] It is understandable that the rotation axis of the first air guide plate 1021 and the rotation axis of the second air guide plate 1022 can be at an acute angle or directly. For example, the first air guide plate 1021 swings up and down, and the second air guide plate 1022 swings left and right.

[0096] Exemplarily, the second air deflector 1022 is arranged at the upstream of the first air deflector 1021 and the second air defusing structure 103, and the second air deflector 1022 can guide the air flow to the first air outlet 101a and the second air outlet 101b to a certain extent without interfering with the operation of the first air deflector 1021 and the second air defusing structure 103, for example, the second air deflector 1022 can play a role of distributing the air flow to a certain extent, so as to realize the encircling air outlet of different modes.

[0097] In some embodiments, the air outlet frame 101 is an integrally formed member, and the air outlet frame 101 participates in defining the appearance surface of the air conditioner 200. In this way, the air outlet frame 101 not only plays its original role, but also serves as the air outlet panel and the air outlet frame of the air conditioner 200, facilitating "one thing with multiple uses", simplifying the assembly process, and improving production efficiency.

[0098] Exemplarily, the air outlet frame 101 includes a fourth plate body 1011 and a fifth plate body 1012, the left and right sides of the fourth plate body 1011 are respectively bent and connected with the fifth plate body 1012, and the second air outlet 101b is formed on each fifth plate body 1012. The fourth plate body 1011 and the fifth plate body 1012 both participate in defining the appearance surface of the air conditioner 200.

[0099] In some embodiments, as shown in Figure 15 and Figure 16 , the air inlet frame 1 is formed with a second mounting groove 1g on one side in the second direction, the groove bottom wall 1f of the second mounting groove 1g is formed with a second air inlet 1b, and the air inlet frame assembly 100 further includes a second filtering structure 4 which is detachably arranged and interference-fitted in the second mounting groove 1g; wherein the second air inlet 1b is formed on the bottom side of the air inlet frame 1, and the second air inlet 1b is arranged in opposite space with the bottom plate 104 located on the lower side of the air inlet frame 1, and the front side of the bottom plate 104 is formed with a avoiding flow guide surface 104a which is recessed backward and extends from bottom to top towards the second air inlet 1b.

[0100] In this way, in the up-down direction, the bottom plate 104 will block at least part of the second air inlet 1b, and the avoiding flow guide surface 104a is recessed backward and extends from bottom to top towards the second air inlet 1b, so that the avoiding flow guide surface 104a can provide a certain air inlet space for the second air inlet 1b, facilitating the improvement of air inlet amount; and when the air conditioner 200 is a cabinet type air conditioner, the bottom plate 104 is placed on the placing surface, the avoiding flow guide surface 104a is arranged, so that the bottom plate 104 not only does not affect the air volume of the second air inlet 1b, but also can take into account a certain supporting area, realizing the stable placement of the air conditioner 200.

[0101] Optionally, the avoiding guide surface 104a can be a smooth curved surface, such as an arc surface, etc., to facilitate smooth air intake; of course, the avoiding guide surface 104a can also be formed as an inclined plane, but is not limited thereto.

[0102] In some embodiments, the air conditioner 200 comprises an air inlet frame assembly 100, an air outlet frame 101, a top cover 106, a bottom plate 104 and a rear box part 105, the top cover 106 is connected to the top of the air outlet frame 101 and the rear box part 105, the bottom plate 104 is connected to the bottom of the air inlet frame 1 and the rear box part 105; the rear box part 105 comprises a rear plate 1051 and two side plates 1052, each side plate 1052 is connected with the air inlet frame 1 and the air outlet frame 102, it can be seen that the air inlet frame 1, the air outlet frame 101 and the rear box part 105 can constitute a shell of the air conditioner 200, the shell is provided with a fan 108 and a heat exchanger 107, the fan 108 is opposite to the air inlet frame 1 front and back, the heat exchanger 107 is inclinedly arranged on the upper side of the fan 108; the fan 108 can be selected as a centrifugal fan.
