[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 19The embodiment of the present invention provides an indoor unit of an air conditioner, comprising a panel body 1, a bottom shell 5, a fan blade 2 and a motor assembly 3. An inspection hole 14 is provided at one end of the length direction of the panel body 1. The upper front surface of the panel body 1 is covered with a panel 11. A water receiving tray 15 is provided at the bottom of the panel body 1. An air guide plate 12 is provided at the front side of the panel body 1 near the bottom. The bottom shell 5 is located behind the panel body 1 and is fixedly connected to the panel body 1. An installation position 51 is provided at the same end of the length direction of the bottom shell 5 as the panel body 1 provided with the inspection hole 14. The fan blade 2 is provided in the panel body 1 and the bottom shell 5. The motor assembly 3 can be detachably installed at the installation position 51 and is connected to one end of the fan blade 2. The cross-sectional area of ​​the inspection hole 14 is at least larger than the cross-sectional area of ​​the motor assembly 3.

[0031] The inspection hole 14 can be set at the left end or the right end of the panel body 1, and accordingly, the installation position 51 can also be set at the left end or the right end of the bottom shell 5, that is, when the inspection hole 14 is set at the left end of the panel body 1, the installation position 51 is set at the left end of the bottom shell 5, and when the inspection hole 14 is set at the right end of the panel body 1, the installation position 51 is set at the right end of the bottom shell 5.

[0032] In actual operation, when the motor assembly 3 needs to be inspected or replaced, the motor assembly 3 can be directly seen and touched through the inspection hole 14, and the maintenance personnel can directly install and disassemble the motor assembly 3 through the inspection hole 14 without removing other larger and heavier components, such as the evaporator or the panel body 1, thereby significantly reducing the difficulty and complexity of disassembly and assembly. This design not only saves time, but also reduces the risk of damage caused by complex disassembly and assembly operations.

[0033] It can be understood that one end of the fan blade 2 is connected to the motor assembly 3. When the motor assembly 3 is removed from the mounting position 51, the fan blade 2 can also be removed together. Of course, a special disassembly hole for the fan blade 2 can also be designed at a suitable position of the panel body 1 or other parts to separate the fan blade 2 from the motor assembly 3 before disassembling the motor assembly 3, so that the motor assembly 3 can be disassembled separately without taking the fan blade 2 out together with the motor assembly 3.

[0034] In one embodiment, in order to facilitate the simultaneous maintenance of the mainboard of the air-conditioning indoor unit, the electrical box component 4 of the air-conditioning indoor unit is arranged at a position close to the inspection hole 14, and the cross-sectional area of ​​the inspection hole 14 is required to be at least larger than the sum of the cross-sectional areas of the motor assembly 3 and the electrical box component 4.

[0035] See also Figure 3 to Figure 4 The air conditioner indoor unit further includes a side panel 13 , which is disposed at one end of the panel body 1 having an inspection hole 14 , and the inspection hole 14 is shielded and covered by the side panel 13 .

[0036] Specifically, the panel body 1 is provided with a mounting screw hole 16, and the side panel 13 is fixed to the end of the panel body 1 by means of fixing screws in the mounting screw hole 16. This connection mode facilitates the quick disassembly and assembly of the side panel 13. When the motor assembly 3 needs to be repaired or replaced, the side cover covering the inspection hole 14 is first removed, and then the motor assembly 3 is repaired or replaced. After the repair or replacement is completed, the side panel 13 is fixed by fixing screws.

[0037] It should be noted that the mounting position 51 can be independently formed by the structure on the bottom shell 5, or can be formed by the structure on the bottom shell 5 and another structure independent of the bottom shell 5. Fig.10 In this embodiment, the mounting position 51 is composed of a structure on the bottom shell 5 and a motor pressure plate 6. The motor pressure plate 6 and the bottom shell 5 are split structures. The motor pressure plate 6 is fixed to the bottom shell 5 by screws, and the mounting position 51 is formed after being connected and fixed.

[0038] In one embodiment, the mounting position 51 is provided with a guide structure and a limit structure, and the motor assembly 3 is embedded in the mounting position 51 along the length direction of the bottom shell 5 through the guide structure, and is limited by the limit structure after rotating a predetermined angle relative to the mounting position 51. The interior of the mounting position 51 is in an arc shape, so as to facilitate the rotation of the motor assembly 3 relative to the mounting position 51.

[0039] In actual operation, when the motor assembly 3 needs to be installed, the motor assembly 3 is first pushed into the installation position 51 along the direction of the guide groove 511. Since the interior of the installation position 51 is in an arc shape, the motor assembly 3 can be smoothly inserted and rotated along the arc shape by a predetermined angle.

[0040] By providing the guide structure and the limit structure, the motor assembly 3 can be embedded in the length direction and smoothly rotated into place, reducing the difficulty and time of operation during the installation process. In addition, the motor assembly 3 can operate stably in the installation position 51, and when disassembly is required, the limit structure can be released by simply rotating the motor assembly 3 in the opposite direction, thereby achieving quick disassembly.

[0041] In one embodiment, the guide structure includes a plurality of guide grooves 511 , and the plurality of guide grooves 511 are arranged at intervals along the inner circumference of the mounting position 51 , and the guiding direction of the guide grooves 511 extends along the length direction of the bottom shell 5 .

[0042] Specifically, the guide grooves 511 are arranged at intervals along the inner circumference of the mounting position 51, so that when the motor assembly 3 is embedded in the mounting position 51, it can be guided by the guide grooves 511 in multiple directions at the same time, thereby avoiding the occurrence of deviation and jamming.

[0043] In one embodiment, the limiting structure includes a plurality of limiting slots 512, which are arranged at intervals along the inner circumference of the installation position 51, and the depth direction of the limiting slots 512 is perpendicular to the length direction of the bottom shell 5. The design of the limiting slots 512 ensures that the motor assembly 3 can be firmly maintained in the correct position after installation, and will not be loosened or displaced even during operation. At the same time, the limiting fixation of the motor assembly 3 can be achieved through a simple rotation operation, which reduces the complexity of installation and allows ordinary technicians to easily complete the installation.

[0044] In one embodiment, a plurality of guide grooves 511 and a plurality of limit slots 512 are staggeredly arranged along the circumferential direction of the mounting position 51. Such a design avoids mutual interference during the rotation process and improves the smoothness of the motor assembly 3 rotating into the limit slot 512.

[0045] In one embodiment, the motor assembly 3 includes a cover 31 and a motor body 32. The motor body 32 is disposed in the cover 31. The outer surface of the cover 31 is provided with a locking portion 33 extending outward. The cross-sectional shape of the locking portion 33 can be a fan-shaped, trapezoidal or triangular shape. The locking portion 33 can enter the interior of the installation position 51 from the guide direction of the guide groove 511, and after rotating a predetermined angle in the installation position 51, it forms a locking fit with the limiting locking groove 512.

[0046] exist Fig.14 At this time, the motor assembly 3 is in an unlocked state, that is, the motor assembly 3 can be withdrawn in the direction opposite to its embedding direction. During the installation process, the motor assembly 3 first slides into the installation position 51 along the guide groove 511 through the locking portion 33 to achieve preliminary positioning. Subsequently, the motor assembly 3 rotates a predetermined angle inside the installation position 51 until the locking portion 33 forms a locking fit with the limiting locking groove 512, thereby achieving the final limiting, and the motor assembly 3 is in a locked state, that is, Fig.15 Status shown.

[0047] The predetermined angle refers to the specific angle that the motor assembly 3 needs to rotate to achieve the precise fit between the locking portion 33 and the limiting slot 512 after entering the installation position 51. The predetermined angle is designed to ensure that the motor assembly 3 can be firmly fixed in the installation position 51 and prevent loosening or displacement during operation. The predetermined angle is determined by the relative positions of the guide slot 511 and the limiting slot 512, and can be set according to actual conditions in actual applications.

[0048] The design of the locking portion 33 cooperating with the guide groove 511 and the limiting locking groove 512 simplifies the installation process of the motor assembly 3 .

[0049] In one embodiment, the mounting position 51 is provided with a stopper 514 located on the rotation path of the motor assembly 3. Specifically, the stopper 514 is designed as a protruding structure in the mounting position 51. After the locking portion 33 of the motor assembly 3 is inserted into the mounting position 51 along the guide groove 511, it starts to rotate until the locking portion 33 contacts the stopper 514. When the contact occurs, it indicates that the motor assembly 3 has rotated to a predetermined correct angle, thereby avoiding excessive rotation.

[0050] In one embodiment, a positioning structure is provided between the bottom of the limiting slot 512 and the locking portion 33, and the positioning structure includes a limiting rib and a groove 331. The limiting rib is provided in one of the limiting slot 512 or the locking portion 33, and the groove 331 is provided in the other of the limiting slot 512 or the locking portion 33.

[0051] In the motor assembly 3 installation structure of the present invention, a positioning structure is provided between the bottom of the limiting slot 512 and the locking portion 33, and the positioning structure includes a limiting rib and a groove 331. The mutual cooperation design of the limiting rib and the groove 331 is intended to further improve the positioning accuracy and fixing stability of the motor assembly 3.

[0052] In this embodiment, the limiting rib is arranged at the bottom of the limiting slot 512, and the groove 331 is arranged on the locking portion 33. When the motor assembly 3 is rotated to a predetermined angle and forms a locking fit with the limiting slot 512, the limiting rib will automatically embed into the groove 331 of the locking portion 33, thereby achieving further positioning and fixing. Through the cooperation of the limiting rib and the groove 331, a multiple limiting effect is formed to ensure the stable fixation of the motor assembly 3. Of course, in other embodiments, the positions of the limiting rib and the groove 331 can be interchanged, that is, the limiting rib is arranged on the locking portion 33, and the groove 331 is arranged at the bottom of the limiting slot 512.

[0053] In one embodiment, the limiting rib and the groove 331 can be designed to be complementary shapes to enhance the interlocking effect. For example, the limiting rib can be designed to be trapezoidal or arc-shaped, and the groove 331 is complementary to its shape. This design can provide a larger contact area and a stronger interlocking force.

[0054] In one embodiment, the mounting position 51 is further provided with an elastic limiting structure 513, and the motor assembly 3 is elastically connected to the mounting position 51 via the elastic limiting structure 513, so that the motor assembly 3 is flexibly connected to the bottom shell 5, thereby avoiding the problem of vibration of the motor assembly 3 being transmitted to the bottom shell 5 and causing resonance of the whole machine.

[0055] In one embodiment, the elastic limiting structure 513 includes a limiting spring piece 5131, and the limiting slot 512 is provided with a limiting spring piece 5131. The limiting spring piece 5131 is designed to achieve flexible connection of the motor assembly 3 through its elastic deformation, thereby effectively absorbing and buffering vibration, and avoiding the problem of vibration being transmitted to the bottom case 5 and causing resonance of the whole machine.

[0056] Specifically, the limiting spring piece 5131 can be made of a highly elastic material, such as spring steel or high-performance plastic. The location and shape of the limiting spring piece 5131 should be adapted to the structure of the limiting slot 512 and the locking portion 33 to ensure that after the motor assembly 3 is installed in place, the limiting spring piece 5131 can contact the locking portion 33 and produce an elastic effect.

[0057] In this embodiment, the two opposite side walls and the bottom of the limiting slot 512 are provided with limiting spring pieces 5131. After the motor assembly 3 is installed in place, the limiting spring piece 5131 limits the clamping portion 33 of the motor assembly 3 tightly in the limiting slot 512 through its elastic restoring force, and provides elastic buffering to prevent vibration transmission. In addition, the elastic force provided by the limiting spring piece 5131 during the installation process can not only fix the motor assembly 3, but also compensate for the installation error to a certain extent, thereby improving the stability of the installation.

[0058] The limit spring piece 5131 can be designed as a multi-layer structure or a composite material to improve its vibration reduction effect and durability. For example, the limit spring piece 5131 can be made of multiple layers of metal sheets or metal and plastic composite materials to enhance the vibration reduction effect through interlayer sliding or the characteristics of the composite material.

[0059] In one embodiment, a limiting spring piece 5131 is disposed on one side of the stop portion 514 close to the locking portion 33 , thereby further improving the vibration reduction effect.

[0060] See also Fig.11 The cover body 31 includes a front cover 311 and a rear cover 312, and the front cover 311 and the rear cover 312 are connected to form a motor installation cavity. The motor body 32 is arranged in the motor installation cavity, the front cover 311 is arranged away from the inspection hole 14, and the rear cover 312 is arranged close to the inspection hole 14. The output shaft of the motor body 32 passes through the front cover 311 and is connected to the fan blade 2.

[0061] Specifically, the front cover 311 and the rear cover 312 can be combined by threaded connection, snap connection or other fixing methods to form a closed motor installation cavity to protect the motor body 32 from the influence of the external environment. During the installation process, the output shaft of the motor body 32 passes through the front cover 311 and is tightly connected to the fan blade 2 to realize the driving function of the motor. The design of the front cover 311 needs to ensure that the rotation of the output shaft is not disturbed.

[0062] In this embodiment, the mounting position 51 is provided with three guide grooves 511 and six limiting slots 512, wherein the three guide grooves 511 are evenly distributed along the circumference of the mounting position 51, and the six limiting slots 512 are divided into two groups on the left and right, arranged along the width direction of the mounting position 51, with three in each group, and also evenly distributed along the circumference. The motor assembly 3 is provided with six locking portions 33, wherein the front cover 311 and the rear cover 312 are evenly distributed with three locking portions 33, and the locking portions 33 on the front cover 311 and the rear cover 312 are arranged to overlap relatively on the left and right, so that during installation, the six locking portions 33 can be synchronously placed in the mounting position 51 only through the three guide grooves 511. After being placed and rotated by a predetermined angle, the three locking portions 33 of the front cover 311 are located in the three limiting slots 512 on the left side of the mounting position 51, and the three locking portions 33 of the rear cover 312 are located in the three limiting slots 512 on the right side of the mounting position 51.

[0063] It should be noted that, in this embodiment, the three limiting slots 512 on the left side of the installation position 51 are not provided with limiting ribs, while the three limiting slots 512 on the right side are provided with limiting ribs. Correspondingly, the three positioning parts 33 of the front cover 311 are not provided with grooves 331, while the three positioning parts 33 of the rear cover 312 are provided with grooves 331. This design enables the positioning parts 33 of the rear cover 312 to achieve a stronger fixing effect through the cooperation between the limiting ribs and the limiting slots 512 during the installation of the motor assembly 3. The cooperation between the limiting ribs and the grooves 331 enhances the locking ability of the rear cover 312 to prevent accidental loosening. The front cover 311 can enter the corresponding limiting slots 512 more quickly, simplifying the installation steps.

[0064] The design of the limiting slot 512 and the locking portion 33 can be adaptively adjusted. For example, limiting ribs can be provided on the limiting slots 512 on both sides of the installation position 51. Correspondingly, grooves 331 are provided on the locking portions 33 of the front cover 311 and the rear cover 312.

[0065] It should be noted that the number and layout of the guide slots 511 and the limit slots 512 can be adjusted according to specific application requirements. For example, the number of guide slots 511 can be increased to improve installation accuracy, or the position of the limit slots 512 can be adjusted to be compatible with different types of motor assemblies 3.

[0066] In one embodiment, a windshield 3111 is provided on one side of the front cover 311 close to the fan blade 2, and the diameter of the windshield 3111 is larger than the diameter of the crossflow fan blade 2. By directly providing the windshield 3111 on the front cover 311, there is no need to design the windshield 3111 separately, which simplifies the structure and makes the assembled structure more compact. At the same time, the provision of the windshield 3111 avoids the problem of air leakage from the installation position 51 when the fan blade 2 is working.

[0067] See also Fig.11 , Fig.13The outer surface of the rear cover 312 is provided with a rotating handle 3121. With such a design, the rotating handle 3121 is used to assist the user in operating when installing or removing the motor assembly 3, providing additional torque support, thereby simplifying the installation and removal process. Specifically, the rotating handle 3121 can be fixed to the outer surface of the rear cover 312 by screws or welding, or can be integrally formed with the rear cover 312. The shape of the rotating handle 3121 can be round, T-shaped, or other ergonomically designed shapes, so that the user can grasp and operate it easily.

[0068] During the installation process, the user can easily rotate the motor assembly 3 to a predetermined angle by grasping the rotating handle 3121 and applying a rotating force, so that the locking portions 33 on the front cover 311 and the rear cover 312 respectively enter the corresponding limiting slots 512, thereby achieving fast and accurate installation. Similarly, when the motor assembly 3 needs to be disassembled, the rotating handle 3121 also provides a convenient means of operation.

[0069] The specific working process is as follows: When the motor assembly 3 needs to be repaired or replaced, please refer to Figures 1 to 3 , open the panel 11 and remove the fixing screws on the mounting screw holes 16 of the right side panel 13, so as to remove the right side panel 13. After removing the right side panel 13, the complete electrical box component 4 and the motor assembly 3 can be seen from the right side. At this time, the main board and other components inside the electrical box component 4 can be repaired. At this time, the motor assembly 3 is in a locked state and cannot be directly removed. Please refer to Figures 17 to 19 The windshield 3111 of the front cover 311 is located on the left side of the motor assembly 3 mounting position 51, blocking the mounting position 51 formed between the motor pressure plate 6 and the bottom shell 5. The six positioning portions 33 on the front cover 311 and the rear cover 312 are located in the six limiting slots 512 of the mounting position 51. The limiting slots 512 and the stopper 514 limit the freedom of the motor assembly 3 in five directions, and can only rotate counterclockwise around the X-axis (i.e. Fig.16 The limiting rib on the limiting spring piece 5131 cooperates with the groove 331 on the locking portion 33, and a certain torque must be applied to it to rotate (note that the vibration caused by the operation of the motor body 32 cannot cause it to disengage). Please refer to Fig.14 , rotate the motor assembly 3 counterclockwise so that the locking portion 33 escapes from the limiting locking groove 512 and enters the guide groove 511.
