[0035] The indoor unit 10 of the air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0036] like Figures 1-10 As shown, the indoor unit 10 of the air conditioner in this embodiment of the present invention includes a frame 100 and a motor mount 200.

[0037] The frame 100 is provided with a mounting post 110 and a first snap-fit ​​structure 120. The motor mount 200 is mounted on the frame 100 and connected to the mounting post 110. The mounting post 110 has a first fixing structure, and the motor mount 200 has a second fixing structure. When the first fixing structure of the mounting post 110 and the second fixing structure of the motor mount 200 correspond, the first fixing structure and the second fixing structure are fixedly connected; or, when the first fixing structure of the mounting post 110 and the second fixing structure of the motor mount 200 correspond, the first fixing structure and the second fixing structure can be fixedly connected by a connecting structure. For example, the first fixing structure is a threaded hole, the second fixing structure is a through hole, and the connecting structure is a screw or bolt assembly.

[0038] The motor base 200 is provided with a first guide structure 210, a limiting structure 220 and a second snap-fit ​​structure 230. The first guide structure 210 is configured to guide the motor base 200 to rotate about an axis relative to the frame 100, so that when the motor base 200 rotates about the axis, the motor base 200 rotates to a connection position that can be connected to the mounting post 110.

[0039] The limiting structure 220 is configured to limit the rotational position of the motor base 200 relative to the frame 100 about an axis, thereby causing the mounting post 110 to move to the connection position with the motor base 200, and causing the first locking structure 120 and the second locking structure 230 to engage in a locking position, thus preventing the motor base 200 from detaching from the frame 100 along the axial direction. In other words, when the motor base 200 is restricted by the limiting structure 220, it moves to the connection position with the mounting post 110 to secure the motor base 200 to the mounting post 110. Furthermore, when the motor base 200 rotates relative to the frame 100 to the connection position with the mounting post 110, the first locking structure 120 and the second locking structure 230 engage to prevent the motor base 200 from detaching from the frame 100.

[0040] Compared with related technologies, the indoor unit 10 of the air conditioner in this embodiment of the present invention has a first guide structure 210 and a limiting structure 220 on its motor base 200. The first guide structure 210 guides the motor base 200 to rotate to the connection position where the motor base 200 connects with the mounting column 110, and the limiting structure 220 limits the mounting column 110 to ensure that the motor base 200 rotates precisely to the connection position, so as to fix the motor base 200 and the mounting column 110, thereby reducing the assembly difficulty of the motor base 200 and the frame 100 and improving the assembly efficiency of the indoor unit 10 of the air conditioner in this embodiment of the present invention. Furthermore, when the motor base 200 moves to the connection position with the mounting column 110, the first snap-fit ​​structure 120 and the second snap-fit ​​structure 230 cooperate to prevent the motor base 200 from separating from the frame 100. Thus, the motor base 200 and the mounting column 110 can be fixed without manual fixation, which further reduces the assembly difficulty of the motor base 200 and the frame 100 and greatly improves the assembly efficiency of the air conditioner indoor unit 10 of this utility model embodiment.

[0041] In some embodiments, such as Figure 4 As shown, the indoor unit 10 of the air conditioner in this embodiment of the present invention also includes a motor cover 300 and a motor. The motor cover 300 is disposed on the side of the motor mount 200 opposite to the frame 100, and the motor is disposed within the accommodating space defined by the motor cover 300 and the motor mount 200. That is, the motor is pressed onto the motor mount 200 by the motor cover 300, thereby enabling the motor to be more stably installed on the frame 100 and improving the stability of the motor installation.

[0042] The motor cover 300 is connected to the mounting post 110 via a connecting structure to fix the motor cover 300, the motor base 200, and the frame 100 together. In other words, the motor cover 300 and the motor base 200 are both fixed using the same connecting structure. For example, the motor cover 300 includes a third fixing structure, and each connecting structure fixes the corresponding first, second, and third fixing structures. Thus, the first, second, and third fixing structures can be fixedly connected using only one connecting structure, simplifying the structure of the motor cover 300, the motor base 200, and the frame 100, thereby reducing the manufacturing cost of the air conditioner indoor unit 10 in this embodiment of the invention.

[0043] In some embodiments, such as Figures 4-8As shown, the motor base 200 includes a mounting block 260 with a first through hole 261 corresponding to the mounting post 110. The first through hole 261 is a stepped hole. The motor cover 300 includes an insertion block 320 that inserts into the stepped hole. The motor cover 300 also has a second through hole 330 that passes through the insertion block 320 and is coaxial with the first through hole 261. The connection structure is a screw. The mounting post 110 has a threaded hole. The screw passes through the second through hole 330 and the first through hole 261 and is threadedly connected to the mounting post 110. Thus, the motor cover 300 and the motor base 200 are fixed to the mounting post 110 using screws. The structure is simple and easy to manufacture.

[0044] In some embodiments, such as Figures 4-8 As shown, a second guide structure 240 is provided on the motor base 200 to guide the motor cover 300 to the connection position connected to the mounting post 110, that is, the position corresponding to the second through hole 330, the first through hole 261, and the mounting post 110. Specifically, the second guide structure 240 is a guide plate, which is located on one side of the first through hole 261. Specifically, there are three mounting blocks 260 and three guide plates, which are arranged sequentially and spaced apart along the circumference of the motor base 200. Each guide plate is correspondingly located at the outer edge of the mounting block 260 and extends upward, and the first through hole 261 is located on the inner side of each guide plate. This not only enables the guide plate to guide the motor cover 300 to the connection position connected to the mounting post 110, but also simplifies the structure.

[0045] Furthermore, a third snap-fit ​​structure 250 is provided on the motor base 200, and a fourth snap-fit ​​structure 310 is provided on the motor cover 300. The second guide structure 240 is configured to guide the motor cover 300 to move along the axial direction. The third snap-fit ​​structure 250 and the fourth snap-fit ​​structure 310 snap together to prevent the motor cover 300 from detaching from the motor base 200 along the axial direction. When the motor cover 300 moves to the connection position of the mounting post 110, the first snap-fit ​​structure 120 and the second snap-fit ​​structure 230 cooperate to prevent the motor base 200 from detaching from the motor cover 300. Thus, the motor base 200, the motor cover 300, and the frame 100 can be fixed without manual fixation, thereby further reducing the assembly difficulty of the motor cover 300, the motor base 200, and the frame 100.

[0046] Specifically, such as Figure 8 and Figure 9 As shown, the third snap-fit ​​structure 250 is a snap-fit, which is disposed on the mounting block 260 and is located on the side of the first through hole 261 away from the motor. The fourth snap-fit ​​structure 310 is a snap-fit ​​protrusion, which is disposed on the motor cover 300.

[0047] In some embodiments, such as Figures 4-8 As shown, a ring 130 is provided at one end of the frame 100, and the motor mount 200 is inserted into the ring 130. The surface of the motor mount 200 inserted into the ring 130 is a first guide structure 210. That is to say, the motor mount 200 is installed with the ring 130 and the mounting post 110 respectively through the first guide structure 210 and the mounting block 260. This not only ensures that the motor mount 200 is stably installed on the frame 100, improving the stability of the motor installation, but also reduces the contact between the motor mount 200 and the frame 100, reducing the noise generated by the motor vibration relative to the frame 100 during operation.

[0048] Furthermore, such as Figure 5 As shown, the first guide structure 210 includes a baffle 211, which cooperates with the mounting post 110 to guide the motor base 200 to rotate about an axis relative to the frame 100. The mounting post 110 is located on the outer side of the ring 130, and the baffle 211 is located on the side of the mounting post 110 opposite to the ring 130. Thus, the mounting post 110 is restricted and guided by the baffle 211, resulting in a simple structure that is easy to manufacture.

[0049] In some embodiments, such as Figure 5 As shown, the limiting structure 220 cooperates with the mounting column 110 to limit the rotational position of the motor base 200 relative to the frame 100 around an axis. The limiting structure 220 is connected to the first guide structure 210. The limiting structure 220 is a limiting plate, which is connected to the baffle 211. Specifically, the limiting plate is an arc-shaped plate adapted to the mounting column 110. One end of the baffle 211 is located at the outer edge of the mounting block 260, and the other end of the arc-shaped plate is connected to one end of the baffle 211. That is, the mounting column 110 moves from one end of the baffle 211 to the other end through the guidance of the baffle 211, and directly enters the limiting plate after the mounting column 110 disengages from the other end of the baffle 211. This achieves precise positioning of the mounting column 110 and the first through hole 261 through the first guide structure 210 and the limiting structure 220, and is easy to operate. Therefore, it further improves the assembly efficiency of the air conditioner indoor unit 10 of this utility model embodiment.

[0050] In some embodiments, such as Figure 5As shown, the first snap-fit ​​structure 120 includes a first snap-fit ​​plate and is disposed on the ring 130. The second snap-fit ​​structure 230 includes a second snap-fit ​​plate and is disposed on the motor base 200. When the motor base 200 moves to the connection position with the mounting post 110, the first snap-fit ​​plate and the second snap-fit ​​plate cooperate to fix the motor base 200 and the mounting post 110 without manual fixation of the frame 100, thereby further reducing the assembly difficulty of the motor base 200 and the frame 100. Moreover, the structure is simple and easy to manufacture.

[0051] In some embodiments, such as Figure 1 As shown, the indoor unit 10 of the air conditioner in this embodiment of the present invention also includes a cross-flow fan. The frame 100 is vertically arranged, the motor mount 200 is located at the upper end of the frame 100, and the motor cover 300 is located on the upper side of the motor mount 200. The motor shaft is parallel to or coincides with the axis, and the motor shaft is vertically arranged. The cross-flow fan is vertically arranged and rotatably mounted on the frame 100. The frame 100 has a volute and / or volute tongue that cooperates with the cross-flow fan. The motor shaft is connected to the cross-flow fan. That is, the volute and / or volute tongue defines the air outlet duct, and the motor drives the cross-flow fan to rotate, thereby promoting the formation of airflow through the duct.

[0052] Furthermore, the motor cover 300 has a groove, and the peripheral wall of the groove has a positioning groove; the groove is located on the side of the motor away from the motor base 200. A positioning rubber block is connected to the motor, and the positioning rubber block is inserted into the groove and the positioning groove. That is, the motor is interference-fitted between the motor cover 300 and the motor base 200 by the positioning rubber block, which not only allows the motor to be installed more stably between the motor cover 300 and the motor base 200, but also buffers the motor, reducing noise generated by motor vibration.

[0053] In some embodiments, the motor mount 200 is provided with a wire-clamping structure, which includes a connecting portion, a pressing portion, and a sealing portion. The connecting portion is connected to the motor mount 200 and extends along the motor's shaft, located on the side of the motor mount 200 opposite to the frame 100. The pressing portion is connected to the connecting portion and spaced apart from the motor mount 200. The sealing portion is connected to the end of the pressing portion away from the connecting portion and is located on the side of the pressing portion facing the motor mount 200. The sealing portion, connecting portion, pressing portion, and motor mount 200 form a wire-passing hole. The sealing portion is spaced apart from the motor mount 200 to form a connection between the outer side of the wire-passing hole and the mounting opening of the wire-passing hole. Thus, the wire-clamping structure on the motor mount 200 secures the motor's wires, making the wire arrangement more orderly and facilitating wire installation and maintenance.

[0054] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
