This achieves a stable connection between the fan body and the fixed sleeve by simply changing the position of the connecting shaft, thereby improving the structural stability of the fan assembly. At the same time, the fan assembly of the present invention can adjust the connection relationship between the fan body and the fixed sleeve by simply changing the position of the connecting shaft, thereby achieving convenient and quick installation of the fan body, thereby improving the installation efficiency of the fan assembly.

[0028] Furthermore, the installation cavity in the fan assembly of the present invention has an opening toward the fixed sleeve and a bottom surface arranged opposite to the opening along the axial direction of the fan body, so that the connecting shaft can be inserted into the installation cavity from the fan body toward the opening on one side of the fixed sleeve. In addition, the fan assembly of the present invention arranges an elastic member in the installation cavity so that the two ends of the elastic member abut against the first end and the bottom surface respectively, and the elastic member is configured to deform when the connecting shaft moves from the second position to the first position, so as to utilize the elastic force generated by the deformation to form damping for the movement of the connecting shaft, thereby achieving the connection between the fan body and the fixed sleeve under the action of the elastic member after the fan assembly is not subjected to external pressure, thereby further improving the installation efficiency of the fan assembly.

[0038] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present invention to those skilled in the art.

[0039] Figure 1 The figure is an exploded view of an air conditioner indoor unit according to one embodiment of the present invention. Figure 2 It is a schematic cross-sectional view of an air-conditioning indoor unit according to an embodiment of the present invention as viewed from the side. Figure 3 This is an exploded view of some components of an air conditioner indoor unit according to one embodiment of the present invention. Figures 1 to 3 As shown, the present invention provides an air-conditioning indoor unit 1. The air-conditioning indoor unit 1 generally includes a casing 11.

[0040] like Figure 1 As shown, the air conditioner indoor unit 1 is provided with a panel frame 12 on the front side of the housing 11. The panel frame 12 is provided with an air inlet 13 and an air outlet 14. The panel frame 12 is provided with a movable panel 15 at the air inlet 13. The movable panel 15 has the following features: Figure 1 The air inlet 13 is shown in a use state with the air inlet 13 opened and in a closed state with the air inlet 13 closed. The movable panel 15 can be controlled to switch states to control the opening and closing of the air inlet 13.

[0041] like Figures 1 to 3 As shown, the air conditioner indoor unit 1 is provided with a heat exchanger 16, a fan assembly 17 and an air duct assembly 18 inside the casing 11. After the air conditioner is started, the indoor air enters the casing 11 through the air inlet 13 under the action of the fan and flows through the heat exchanger 16 for heat exchange, and is blown out from the air outlet 14 under the guidance of the air duct assembly 18 to transport the heat-exchanged airflow into the room.

[0042] In a specific embodiment, Figure 1 As shown, the air conditioner indoor unit 1 can be a built-in unit. The housing 11 can be embedded into the cabinet 2 through the front installation opening 21. Specifically, the air conditioner indoor unit 1 can be divided into two parts during installation: the front part primarily includes the panel frame 12, the movable panel 15, the display panel box, the motor and connecting rod mechanism that drives the movable panel 15, and the water tray 19; the rear part includes the housing 11, the heat exchanger 16, the fan assembly 17, and the air duct assembly 18. During assembly, the rear part is installed into the cabinet 2 first, followed by the front part.

[0043] Therefore, during maintenance, all components of the rear portion can be repaired by removing the front portion. In addition, after the air conditioner indoor unit 1 is embedded in the cabinet 2, the rear portion is invisible and non-designed. This can reduce the appearance requirements of the rear portion and reduce the production cost of the air conditioner indoor unit 1.

[0044] The air conditioner indoor unit 1 of the present embodiment adopts a front-to-front air intake and exhaust method, and adopts a dual-channel top solution. The top channel has stronger air intake, which fully guides the indoor airflow to the rear heat exchanger 16, avoiding the phenomenon of heat exchanger 16 icing caused by insufficient air volume, thereby improving heat exchange efficiency. At the same time, the air conditioner indoor unit 1 of the present embodiment can achieve front-to-front air intake and exhaust, without being restricted by the cabinet 2, and realizes the embedded installation of the air conditioner indoor unit 1 while ensuring high heat exchange efficiency.

[0045] In some embodiments, the housing 11 has a front opening 3, through which the fan assembly 17 is installed. The air duct assembly is detachably connected to the bottom of the housing 11, and a removal opening 4 for removing the fan assembly 17 is formed above the air duct assembly 18. A panel frame 12 is detachably disposed on the front side of the housing 11 and is used to open or close the front opening 3, thereby opening or closing the removal opening 4, thereby facilitating the removal and installation of the fan assembly 17 when the removal opening 4 is open.

[0046] The air conditioner indoor unit 1 of the embodiment of the present invention may include a housing 11, an air duct assembly 18, and a panel frame 12. The housing 11 has a front opening 3, and a fan assembly 17 is installed in the housing 11. The air duct assembly 18 is detachably connected to the bottom of the housing 11, and a disassembly opening 4 for disassembling the fan assembly 17 is formed above the air duct assembly 18. The panel frame 12 is detachably arranged on the front side of the housing 11 and is used to open or close the front opening 3 to open or close the disassembly opening 4. Therefore, the air conditioner indoor unit 1 of the embodiment of the present invention can open the disassembly opening 4 for disassembling the fan assembly 17 by removing the panel frame 12 located on the front side of the housing 11, so that the fan assembly 17 can be disassembled, thereby achieving convenient and quick disassembly and assembly of the fan assembly 17, thereby improving the disassembly efficiency of the fan assembly 17.

[0047] Furthermore, if Figure 1 and Figure 2 As shown, the heat exchanger 16 is covered in front of and above the fan assembly 100. The water receiving tray 19 is provided at the front and lower part of the heat exchanger 16 to receive the condensed water condensed on the heat exchanger 16 and the defrosted water produced by the defrosting of the heat exchanger 16. In addition, the lower surface of the water receiving tray 19 and the upper surface of the air duct assembly 18 together define an air supply duct to guide the airflow after heat exchange to flow toward the air outlet 14. Figure 3 As shown, the air conditioner indoor unit 1 is configured such that after the water receiving pan 19 is removed, a disassembly opening 4 is defined between the front lower portion of the heat exchanger 16 and the upper portion of the air duct assembly 18 .

[0048] Thus, after the water tray 19 is removed, a maintenance space sufficient to accommodate the entry and exit of the fan assembly 17 can be formed above the air duct assembly 18. Specifically, Figure 3As shown, during maintenance, the front panel frame 12 and the front water receiving tray 19 can be removed in sequence to make room for removing the fan assembly 17 at the rear.

[0049] The air conditioner indoor unit 1 of the present embodiment optimizes the disassembly process, so that when repairing the fan assembly 17, the refrigerant does not need to be recovered first. The fan assembly 17 can be repaired or replaced directly through the disassembly port 4, simplifying the repair process and improving repair efficiency. This design can reduce repair time and cost, and reduce the risk of leakage caused by improper refrigerant handling.

[0050] In some embodiments, as Figure 3 As shown, the fan assembly 17 includes a fan assembly 100, a motor assembly 200 for driving the fan assembly 100 to rotate, and a fixed sleeve ( Figure 3 Specifically, the fixed sleeve and the motor assembly 200 are respectively installed on the left and right sides of the interior of the housing 11 to respectively support the two ends of the fan assembly 100 in the axial direction of the fan assembly 100. Figures 4 to 7 The structure of the fan assembly 100 of the present invention is introduced in detail.

[0051] Figure 4 It is a structural schematic diagram of a fan assembly in an air-conditioning indoor unit according to an embodiment of the utility model, wherein the connecting shaft is located at a first position. Figure 5 yes Figure 4 A schematic cross-sectional view of section A of the fan assembly is shown. Figure 6 It is a structural schematic diagram of a fan assembly in an air-conditioning indoor unit according to another embodiment of the present utility model, wherein the connecting shaft is located at the second position. Figure 7 yes Figure 6 The cross-sectional diagram of the B part of the fan assembly is shown in FIG. Figure 4 and Figure 6 As shown, the fan assembly 17 includes a fan assembly 100, a motor assembly 200, and a fixed shaft sleeve 300. The motor assembly 200 and the fixed shaft sleeve 300 are detachably mounted inside the housing 11, and the fan assembly 100 is detachably mounted between the motor assembly 200 and the fixed shaft sleeve 300. In addition, the fan assembly 100 generally includes a fan body 110 and a connecting shaft 120.

[0052] In this embodiment, the fan body 110 is rotatably mounted in the housing 11 of the air conditioner indoor unit 1, with one end thereof facing the fixed shaft sleeve 300 in the housing 11. The fan body 110 is provided with a plurality of blades at intervals for promoting air flow. Figures 4 to 7As shown, the fan body 110 can be a cross-flow fan, and the axial direction of the fan body 110 is consistent with the length direction of the housing 11. In a specific embodiment, the air conditioner indoor unit 1 can be a horizontal air conditioner, the length direction of the housing 11 can be horizontal, and the axial direction of the fan body 110 can also be horizontal.

[0053] In addition, the connecting shaft 120 is movably provided at one end of the fan body 110 adjacent to the fixed sleeve 300 along the axial direction of the fan body 110, for connecting the fan body 110 and the fixed sleeve 300. Figure 4 and Figure 5 As shown, the connecting shaft 120 is configured to release the connection between the fan body 110 and the fixing sleeve 300 when it moves to a first position away from the fixing sleeve 300 .

[0054] Specifically, when disassembling the fan assembly 100, Figure 5 As shown, when the connecting shaft 120 moves along the axial direction of the fan body 110 to the first position away from the fixed sleeve 300, it is disengaged from the mounting hole 310 provided in the middle portion of the fixed sleeve 300, thereby releasing the connection between the fan body 110 and the fixed sleeve 300. As a result, the fan assembly 100 can be removed smoothly.

[0055] The fan assembly 100 of an embodiment of the present invention may include a fan body 110 and a connecting shaft 120, wherein the fan body 110 is rotatably installed in the casing 11 of the air-conditioning indoor unit 1, and one end of the fan body 110 is arranged opposite to the fixed shaft sleeve 300 in the casing 11, and the connecting shaft 120 is movably arranged along the axial direction of the fan body 110 at one end of the fan body 110 adjacent to the fixed shaft sleeve 300, for connecting the fan body 110 and the fixed shaft sleeve 300, and the connecting shaft 120 is configured to release the connection relationship between the fan body 110 and the fixed shaft sleeve 300 when it moves to a first position away from the fixed shaft sleeve 300, so that the connection relationship between the fan body 110 and the fixed shaft sleeve 300 can be adjusted by changing the position of the connecting shaft 120, thereby realizing convenient and quick disassembly and assembly of the fan body 110, thereby improving the disassembly efficiency of the fan assembly 100.

[0056] In some embodiments, as Figure 5 and Figure 7 As shown, one end of the fan body 110 adjacent to the fixed sleeve 300 is recessed inward to form a mounting cavity 111. Mounting cavity 111 extends along the axial direction of the fan body 110. Specifically, mounting cavity 111 is recessed inward from the middle portion of the end of the fan body 110 adjacent to the fixed sleeve 300. A cylindrical mounting space is formed within mounting cavity 111, and the axial direction of mounting cavity 111 coincides with the axial direction of fan body 110.

[0057] Furthermore, if Figure 5 and Figure 7 As shown, the axial direction of the connecting shaft 120 coincides with the axial direction of the fan body 110. In addition, the connecting shaft 120 has a first end 121 inserted into the installation cavity 111 and a second end 122 extending from the installation cavity 111. Specifically, the first end 121 and the second end 122 are connected and coaxially arranged. Figure 6 and Figure 7 As shown, the connecting shaft 120 is further configured to have its second end 122 inserted into the fixing sleeve 300 when moved to a second position close to the fixing sleeve 300 , so as to mount the fan body 110 on the fixing sleeve 300 .

[0058] Specifically, when installing the fan assembly 100, one end of the fan body 110 is connected to the transmission shaft 210 in the motor assembly 200, and the other end of the fan body 110 is aligned with the fixed sleeve 300 in the housing 11. Figure 7 As shown, when the connecting shaft 120 moves along the axial direction of the fan body 110 to a second position close to the fixed sleeve 300, the fixed sleeve 300 is inserted into the mounting hole 310 provided in the middle of the fixed sleeve 300, thereby establishing a connection between the fan body 110 and the fixed sleeve 300 and installing the fan body 110 on the fixed sleeve 300. Thus, the fan assembly 100 is installed.

[0059] The fan assembly 100 of the present embodiment of the present invention forms a mounting cavity 111 by directly recessing one end of the fan body 110 adjacent to the fixed sleeve 300. The mounting cavity 111 extends along the axial direction of the fan body 110, thereby forming a mounting space for the connecting shaft 120. Furthermore, the fan assembly 100 of the present embodiment of the present invention arranges the axial direction of the connecting shaft 120 to coincide with the axial direction of the fan body 110. The connecting shaft 120 has a first end 121 inserted into the mounting cavity 111 and a second end 122 extending from the mounting cavity 111. The connecting shaft 120 is configured such that, when moved to a second position adjacent to the fixed sleeve 300, the second end 122 is inserted into the fixed sleeve 300, thereby mounting the fan body 110 on the fixed sleeve 300. This achieves a stable connection between the fan body 110 and the fixed sleeve 300 simply by changing the position of the connecting shaft 120, thereby improving the structural stability of the fan assembly 100. At the same time, the fan assembly 100 of the embodiment of the present invention can adjust the connection relationship between the fan body 110 and the fixed shaft sleeve 300 by simply changing the position of the connecting shaft 120, thereby realizing convenient and quick installation of the fan body 110, thereby improving the installation efficiency of the fan assembly 100.

[0060] In some embodiments, as Figure 5 and Figure 7 As shown, the connecting shaft 120 is provided with a handle 123 protruding outwardly in the radial direction of the connecting shaft 120 at a position adjacent to the second end 122 . The handle 123 is used to drive the connecting shaft 120 to move when subjected to external pressure.

[0061] Specifically, when disassembling the fan assembly 100, Figure 5 As shown, external pressure is applied to the handle 123 in a direction away from the fixed sleeve 300 in the axial direction of the fan body 110, driving the connecting shaft 120 to move in a direction away from the fixed sleeve 300 until it reaches the first position and the second end 122 is disengaged from the mounting hole 310, thereby releasing the connection between the fan body 110 and the fixed sleeve 300. In this way, the fan assembly 100 can be removed smoothly.

[0062] In addition, when installing the fan assembly 100, Figure 7 As shown, external pressure is applied to the handle 123 in the axial direction of the fan body 110 toward the fixed sleeve 300, driving the connecting shaft 120 to move in a direction close to the fixed sleeve 300 until it reaches the second position so that the second end 122 is inserted into the fixed sleeve 300 through the mounting hole 310, thereby establishing a connection between the fan body 110 and the fixed sleeve 300 and installing the fan body 110 on the fixed sleeve 300. Thus, the fan assembly 100 is installed.

[0063] The fan assembly 100 of the embodiment of the present invention facilitates manual axial movement of the connecting shaft 120 by providing a handle 123 on the connecting shaft 120, thereby achieving convenient and quick installation and removal of the fan assembly 100, thereby further ensuring the installation and removal efficiency of the fan assembly 100.

[0064] In some embodiments, as Figure 5 and Figure 7As shown, the mounting cavity 111 has an opening 112 facing the fixed sleeve 300 and a bottom surface 113 disposed opposite the opening 112 along the axial direction of the fan body 110. This allows the connecting shaft 120 to be inserted into the mounting cavity 111 from the fan body 110 toward the opening 112 on one side of the fixed sleeve 300. Furthermore, the fan assembly 100 also includes an elastic member 130. The elastic member 130 is disposed within the mounting cavity 111, with its ends abutting against the first end 121 of the connecting shaft 120 and the bottom surface 113, respectively. Specifically, the elastic member 130 is configured to deform when the connecting shaft 120 moves from the second position to the first position, thereby utilizing the elastic force generated by the deformation to damp the movement of the connecting shaft 120. In other words, the elastic force of the elastic member 130 causes the connecting shaft 120 to tend to stabilize in the second position. To move the connecting shaft 120 from the second position to the first position, a force sufficient to overcome the elastic force of the elastic member 130 is applied to the connecting shaft 120.

[0065] The mounting cavity 111 of the fan assembly 100 of the present embodiment has an opening 112 facing the fixed sleeve 300 and a bottom surface 113 disposed opposite the opening 112 along the axial direction of the fan body 110. This allows the connecting shaft 120 to be inserted into the mounting cavity 111 from the fan body 110 toward the opening 112 on one side of the fixed sleeve 300. Furthermore, the fan assembly 100 of the present embodiment disposes an elastic member 130 within the mounting cavity 111, with both ends of the elastic member 130 abutting against the first end 121 and the bottom surface 113, respectively. The elastic member 130 is configured to deform when the connecting shaft 120 moves from the second position to the first position, thereby utilizing the elastic force generated by the deformation to damp the movement of the connecting shaft 120. This allows the connecting shaft 120 to automatically move from the first position to the second position under the action of the elastic member 130 when the fan assembly 100 is no longer subject to external pressure, thereby achieving connection between the fan body 110 and the fixed sleeve 300 and further improving the installation efficiency of the fan assembly 100. At the same time, the elastic member 130 continuously provides a supporting force to the connecting shaft 120 in the direction toward the fixed sleeve 300 under the action of the elastic force, so that the connecting shaft 120 has a movement tendency to stabilize in the second position, further improving the structural stability of the fan assembly 100.

[0066] In some embodiments, as Figure 5 and Figure 7As shown, the first end 121 of the connecting shaft 120 has an annular baffle 1211 that protrudes outward from the outer surface of the connecting shaft 120 in the radial direction of the connecting shaft 120. The annular baffle 1211 is configured to abut against the end of the elastic member 130 away from the bottom surface 113. As a result, the elastic member 130 applies a supporting force to the outer circumference of the first end 121 of the connecting shaft 120 under the action of the elastic force, thereby increasing the force-bearing area of the first end 121 of the connecting shaft 120 and improving the uniformity of the application of the supporting force, thereby providing a more stable supporting force for the connecting shaft 120 toward the fixed sleeve 300.

[0067] Specifically, the elastic member 130 may be a spring whose extension direction is parallel to the axial direction of the fan body 110. In one embodiment, the elastic member 130 may also include a plurality of springs arranged at intervals to apply a supporting force to the connecting shaft 120 at various positions of the annular baffle 1211. In another embodiment, as Figure 5 and Figure 7 As shown, the elastic member 130 may include a spring coaxially arranged with the connecting shaft 120, and the radial dimension of the spring is larger than the inner diameter dimension of the annular baffle 1211 and smaller than the outer diameter dimension of the annular baffle 1211, so as to apply a supporting force to the outer peripheral side of the first end 121 of the connecting shaft 120, thereby ensuring the uniformity of the application of the supporting force and improving the structural stability of the fan assembly 100.

[0068] In some embodiments, as Figure 5 and Figure 7 As shown, the fan body 110 has an annular stopper 114 protruding inwardly in the radial direction of the fan body 110 at the opening 112 of the mounting cavity 111. The annular stopper 114 is configured to abut against the annular baffle 1211 when the connecting shaft 120 moves from the first position to the second position, thereby preventing the first end 121 from falling out of the mounting cavity 111, thereby further improving the structural stability of the fan assembly 100.

[0069] Furthermore, if Figure 5 and Figure 7As shown, the annular limiting portion 114 is sleeved on the outer circumference of the connecting shaft 120. The hollow portion 114 is formed with an axial hole 1141 for inserting the connecting shaft 120. Specifically, the radial dimension of the axial hole 1141 is larger than the inner diameter of the annular baffle 1211 and smaller than the outer diameter of the annular baffle 1211. This allows the connecting shaft 120 to move axially within the axial hole 1141 while preventing the first end 121 from escaping from the mounting cavity 111 through the axial hole 1141, thereby further ensuring the structural stability of the fan assembly 100. In addition, the radial dimension of the axial hole 1141 can match the inner diameter of the annular baffle 1211, so that the axial hole 1141 and the first end 121 of the connecting shaft 120 are arranged with a clearance fit, thereby limiting the shaking of the connecting shaft 120 in the radial direction of the fan body 110, thereby improving the structural stability of the fan assembly 100.

[0070] In some embodiments, as Figure 5 and Figure 7 As shown, the ratio of the dimension of the annular limiting portion 114 in the axial direction of the fan body 110 to the dimension of the connecting shaft 120 in the axial direction thereof is 0.2 to 0.5, thereby constraining the movement of the connecting shaft 120 in the radial direction of the fan body 110. Specifically, the ratio of the dimension of the annular limiting portion 114 in the axial direction of the fan body 110 to the dimension of the connecting shaft 120 in the axial direction thereof may be 0.25 to 0.35. In a specific embodiment, the ratio of the dimension of the annular limiting portion 114 in the axial direction of the fan body 110 to the dimension of the connecting shaft 120 in the axial direction thereof may be 0.27. This ensures that a sufficient length of the connecting shaft 120 extends out of the mounting cavity 111 to connect with the fixed sleeve 300, while ensuring that the length of the portion of the connecting shaft 120 connected to the fan body 110 is sufficient to limit the shaking of the connecting shaft 120 in the radial direction of the fan body 110, thereby further ensuring the structural stability of the fan assembly 100.

[0071] In some embodiments, as Figure 5 and Figure 7As shown, the ratio of the dimension of the annular limiting portion 114 in the axial direction of the fan body 110 to the dimension of the connecting shaft 120 in the axial direction thereof is 0.2 to 0.5, thereby constraining the movement of the connecting shaft 120 in the radial direction of the fan body 110. Specifically, the ratio of the dimension of the annular limiting portion 114 in the axial direction of the fan body 110 to the dimension of the connecting shaft 120 in the axial direction thereof may be 0.25 to 0.35.
