[0038] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will appreciate the applicability of other processes and / or the use of other materials.

[0040] An air conditioner 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0041] like Figures 1 to 9 As shown, an air conditioner 100 according to an embodiment of the present invention includes: a casing assembly, a fan component, a heat exchanger assembly 2, and a motor cover assembly 3. The casing assembly has an air inlet and an air outlet. The fan component is disposed within the casing assembly and includes a fan wheel and a motor. The heat exchanger assembly 2 is disposed within the casing assembly and includes a heat exchanger 21 and a refrigerant connection pipe 22 connected to the heat exchanger 21. The heat exchanger 21 is located between the air inlet and the fan wheel. The motor is connected to the fan wheel to drive the fan wheel to rotate, thereby driving indoor air into the casing assembly through the air inlet. After heat exchange in the heat exchanger 21, the air is discharged into the indoor space through the air outlet to achieve temperature regulation of the indoor air.

[0042] The motor cover assembly 3 is provided on the outside of the motor, and at least a portion of the refrigerant connecting pipe 22 is located above the motor cover assembly 3. The motor cover assembly 3 includes at least a first motor cover 31, a second motor cover 32, and a water retaining member 33. The first motor cover 31 and the second motor cover 32 are independently formed and connected, and at least a portion of the water retaining member 33 is located directly above the connection between the first motor cover 31 and the second motor cover 32. In other words, in the up and down directions, at least a portion of the water retaining member 33 is blocked between the connection between the first motor cover 31 and the second motor cover 32 and the refrigerant connecting pipe 22. It is understandable that during the operation of the air conditioner 100, such as when the air conditioner 100 is in cooling mode, the refrigerant temperature in the refrigerant connecting pipe 22 is low, resulting in the formation of condensation water on the refrigerant connecting pipe 22. Therefore, when condensation water is generated on the part of the refrigerant connecting pipe 22 located directly above the connection between the first motor cover 31 and the second motor cover 32, and the condensation water drips downward under the action of gravity, the part of the water blocking component 33 located directly above the connection between the first motor cover 31 and the second motor cover 32 can better prevent the condensation water from dripping into the connection position of the first motor cover 31 and the second motor cover 32, so as to avoid the condensation water from passing through the gap at the connection between the first motor cover 31 and the second motor cover 32 and contacting the motor, thereby avoiding the risk of live parts such as the motor being soaked in water, thereby improving the stability of the air conditioner 100.

[0043] According to the air conditioner 100 of the embodiment of the present invention, the water-blocking component 33 is located directly above the connection between the first motor cover 31 and the second motor cover 32, which can effectively prevent condensation water from dripping into the connection position of the first motor cover 31 and the second motor cover 32, so as to avoid condensation water from passing through the gap at the connection between the first motor cover 31 and the second motor cover 32 and contacting the motor, thereby avoiding the risk of live parts such as the motor being immersed in water, thereby improving the stability of the air conditioner 100.

[0044] According to some embodiments of the present invention, the water retaining member 33 includes a water retaining body 331, the water retaining body 331 being located just above the connection between the first motor cover 31 and the second motor cover 32, a side edge of the water retaining body 331 away from the first motor cover 31 being formed with a first water retaining flange 332 extending upward, and a side edge of the water retaining body 331 away from the first water retaining flange 332 being formed as a drainage side edge. In other words, the water retaining body 331 can better catch condensation water dripping just above the connection between the first motor cover 31 and the second motor cover 32, and the first water retaining flange 332 can prevent the condensation water falling on the water retaining body 331 from flowing toward the second motor cover 32 on the side of the water retaining body 331 away from the first motor cover 31, and the condensation water falling on the water retaining body 331 can be discharged toward the first motor cover 31 along the water retaining body 331 and through the side of the water retaining body 331 away from the first water retaining flange 332, i.e., the drainage side edge. Therefore, the first water retaining flange 332 can better limit the flow direction of the condensation water on the water retaining body 331, and at the same time, the drainage side can prevent the condensation water from staying on the water retaining component 33, thereby preventing the condensation water from gathering on the water retaining body 331 and causing the condensation water to overflow the water retaining component 33, and further preventing the overflowed water from flowing downward along the water retaining component 33 to the connection between the first motor cover 31 and the second motor cover 32.

[0045] In a specific example, a drainage channel 314 and a drain outlet 315 located at the bottom of the drainage channel 314 are formed on the surface of the side of the first motor cover 31 facing away from the motor. The drainage channel 314 can be connected to a structure such as a water receiving tray of the air conditioner 100 for discharging condensed water through the drain outlet 315. Since part of the refrigerant connecting pipe 22 is located directly above the first motor cover 31, the condensation water dripping from the refrigerant connecting pipe 22 above can be caught by the drainage channel 314, and the condensation water falling on the water retaining component 33 can enter the drainage channel 314 through the drainage side and further be discharged into the water receiving tray through the drain outlet 315 to avoid the condensation water from staying on the motor cover assembly 3.

[0046] According to some embodiments of the present invention, a water retaining rib 311 is formed on an edge of one side of the first motor cover 31 near the second motor cover 32. The water retaining body 331 is located above the water retaining rib 311, and the drainage side is located on the side of the water retaining rib 311 facing away from the second motor cover 32. Thus, the water retaining rib 311 can prevent condensation water falling on the first motor cover 31 from flowing toward the second motor cover 32, thereby preventing condensation water from entering the connection between the first motor cover 31 and the second motor cover 32. That is, the water retaining rib 311 can prevent condensation water falling on the first motor cover 31 from overflowing, and allows the condensation water falling on the first motor cover 31 to flow along the drainage channel 314 and other structures on the first motor cover 31, and finally drain into the water receiving tray, thereby ensuring the stability of the motor cover assembly 3 in guiding the discharge of condensation water.

[0047] According to some embodiments of the present invention, the water retaining member 33 further includes a guide flange 333 provided on the drainage side and extending downward, the guide flange 333 being located on the side of the water retaining rib 311 facing away from the second motor cover 32, and the lower end of the guide flange 333 being located below the upper end of the water retaining rib 311. In other words, when condensation water falling on the water retaining body 331 flows toward the first motor cover 31 through the drainage side, it will flow downward along the side of the guide flange 333 facing away from the water retaining rib 311 and eventually flow onto the first motor cover 31, thereby avoiding the risk of water leakage caused by the condensation water flowing to the discharge side through the gap between the water retaining body 331 and the water retaining rib 311 to the side of the water retaining rib 311 facing the second motor cover 32.

[0048] In some embodiments, the guide flange 333 is formed as a guide surface 3331 on the side of the water retaining rib 311. In the direction from the fixed end to the free end of the guide flange 333, the guide surface 3331 extends obliquely in the direction away from the water retaining rib 311, so that the guide surface 3331 can play a good guiding role in the assembly of the water retaining component 33, thereby reducing the difficulty of assembling the water retaining component 33 and the first motor cover 31. In a specific example, the water retaining component 33 also includes a connecting portion 335. The guide flange 333 and the connecting portion 335 are spaced apart along the arrangement direction of the first motor cover 31 and the second motor cover 32. A receiving groove 337 located on the lower side of the water retaining body 331 is formed between the guide flange 333 and the connecting portion 335, and at least a portion of the water retaining rib 311 is received in the receiving groove 337.

[0049] In some embodiments, the vertical distance between the lower end of the guide flange 333 and the upper end of the water retaining rib 311 is greater than 5 mm. Since condensation droplets are typically about 5 mm in size, controlling the vertical distance between the lower end of the guide flange 333 and the upper end of the water retaining rib 311 to be greater than 5 mm prevents condensation droplets from flowing through the gap between the guide flange 333 and the water retaining rib 311 to the side of the water retaining rib 311 facing the second motor cover 32. The vertical distance between the lower end of the guide flange 333 and the upper end of the water retaining rib 311 can be 5.2 mm, 5.5 mm, 5.7 mm, 6 mm, 6.3 mm, 6.6 mm, 7 mm, 7.5 mm, etc., without specific limitation.

[0050] According to some embodiments of the present invention, the water retaining body 331 extends downwardly in a direction from the first water retaining flange 332 to the drainage side. Therefore, condensation water on the water retaining body 331 can flow toward the drainage side under its own weight, thereby preventing condensation water from lingering on the water retaining body 331 and accelerating the efficiency of condensation water leaving the water retaining member 33.

[0051] According to some embodiments of the present invention, the first motor cover 31 and the second motor cover 32 are arranged along the axial direction of the motor, and the first water-retaining flange 332 of the water-retaining body 331 extends along the circumference of the motor. Particularly, since the first motor cover 31 and the second motor cover 32 are arranged along the axial direction of the motor, the connection position of the first motor cover 31 and the second motor cover 32 is roughly arranged along the circumference of the motor. Therefore, by extending the first water-retaining flange 332 of the water-retaining body 331 along the circumference of the motor, the size of the water-retaining body 331 and the first water-retaining flange 332 in the circumferential direction of the motor can be increased, thereby increasing the shielding area of ​​the water-retaining body 331 at the connection between the first motor cover 31 and the second motor cover 32 in the circumferential direction of the motor. At the same time, it is ensured that the first water-retaining flange 332 can completely cover the water-retaining body 331 in the circumferential direction of the motor to prevent condensation water on the water-retaining body 331 from flowing to the second motor cover 32, thereby improving the reliability of the water-retaining component 33 in blocking water.

[0052] According to some embodiments of the present invention, the water retaining body 331 has a first end and a second end at its circumferential ends in the motor direction. In the direction from the first end to the second end, the water retaining body 331 extends downwardly at an angle, and a second water retaining flange 334 extending upward is formed on the second end. The second water retaining flange 334 is connected to the first water retaining flange 332. In other words, condensation water on the water retaining body 331 can flow toward the second end under its own weight. The second water retaining flange 334 can prevent the condensation water from flowing through the second end toward the connection between the first motor cover 31 and the second motor cover 32. At the same time, the condensation water flowing to the second end can flow along the second water retaining flange 334 toward the first motor cover 31, thereby improving the drainage efficiency of the condensation water on the water retaining body 331 while allowing the condensation water to flow stably toward the first motor cover 31.

[0053] In a specific example, a third water-retaining flange 336 is formed on one end of the guide flange 333 near the second end in the circumferential direction of the motor. The third water-retaining flange 336 flows along the axial direction of the motor toward a direction away from the water-retaining rib 311, and the upper end of the third water-retaining flange 336 is connected to the end of the second water-retaining flange 334 away from the first water-retaining flange 332, so that a continuous water-retaining structure can be formed by the first water-retaining flange 332, the second water-retaining flange 334 and the third water-retaining flange 336 to ensure that the condensation water on the water-retaining component 33 can flow stably to the first motor cover 31.

[0054] According to some embodiments of the present invention, the first motor cover 31 is located on the outer peripheral side of the motor, and the second motor cover 32 is located on the side of the motor away from the wind wheel. In other words, the first motor cover 31 can protect and fix the motor from the outer peripheral side of the motor, and the second motor cover 32 is arranged along the axial direction of the motor and can protect and fix the motor from the side of the motor away from the wind wheel, which can ensure the protection performance of the motor cover assembly 3 on the motor and the stability of the fixation. In addition, in the axial direction of the motor, the first motor cover 31 can better cover and block the top of the motor, so that the first motor cover 31 is located directly below most of the refrigerant connecting pipes 22, so that the first motor cover 31 can catch most of the condensation water dripping from the refrigerant connecting pipes 22. Therefore, it is only necessary to set the drainage channel 314 on the first motor cover 31, eliminating the need to set drainage structures such as the drainage channel 314 on the second motor cover 32. Moreover, since the second motor cover 32 is located on the side of the motor away from the wind wheel, when the motor needs to be removed, the motor can be pulled out from the second motor cover 32 after the second motor cover 32 is removed. Compared with the refrigerant connecting pipe 22 arranged above the first motor cover 31, the operating space on the side of the motor away from the wind wheel is larger, which can reduce the difficulty of disassembling the motor.

[0055] According to some embodiments of the present invention, the casing assembly is formed with a avoidance opening 11 located on the outer peripheral side of the fan, and the refrigerant connecting pipe 22 extends out of the casing assembly through the avoidance opening 11. In the axial direction of the motor, the first water-retaining flange 332 is located on the side of the avoidance opening 11 away from the wind wheel. It is understandable that during the installation of the air conditioner 100, when the installer adjusts the position of the refrigerant connecting pipe 22 on the outer portion of the casing assembly, the refrigerant connecting pipe 22 in the casing assembly may be offset in position. However, due to the limitation of the inner peripheral wall of the avoidance opening 11, the offset amplitude of the refrigerant connecting pipe 22 is controlled within the coverage range of the avoidance opening 11, that is, the refrigerant connecting pipe 22 cannot be offset to the side of the avoidance opening 11 away from the wind wheel. Therefore, by setting the first water-retaining flange 332 on the side of the avoidance opening 11 away from the wind wheel, even if the refrigerant connecting pipe 22 is offset to the edge of the avoidance opening 11 away from the wind wheel, the water-retaining component 33 can still catch the condensation water dripping from the refrigerant connecting pipe 22 to ensure the reliability of the water-retaining component 33.

[0056] According to some embodiments of the present invention, the height of the first water retaining flange 332 protruding from the water retaining body 331 is greater than 5 mm. Since condensation droplets are typically around 5 mm in size, setting the height of the first water retaining flange 332 protruding from the water retaining body 331 to greater than 5 mm prevents condensation from overflowing the first water retaining flange 332 and flowing to the side of the first water retaining flange 332 facing the second motor cover 32. The height of the first water retaining flange 332 protruding from the water retaining body 331 can be 5.2 mm, 5.5 mm, 5.7 mm, 6 mm, 6.3 mm, 6.6 mm, 7 mm, 7.5 mm, and so on, without specific limitation.

[0057] According to some embodiments of the present invention, the water retaining member 33 is provided on the second motor cover 32. Thus, through the connection between the water retaining member 33 and the second motor cover 32, the position between the water retaining member 33 and the second motor cover 32 can be well maintained, that is, the relative position between the water retaining member 33 and the second motor cover 32 remains fixed, so that the water retaining member 33 can be stably maintained at a position at least partially above the connection between the first motor cover 31 and the second motor cover 32, thereby ensuring the reliability of the water retaining member 33 in blocking water.

[0058] According to some embodiments of the present invention, the water retaining member 33 is integrally formed with the second motor cover 32. Thus, the integrally formed structure not only ensures the structural and performance stability of the water retaining member 33 and the second motor cover 32, but also facilitates molding and is simple to manufacture. In addition, the assembly parts and connection process used to connect the water retaining member 33 and the second motor cover 32 are eliminated, which reduces production costs and greatly improves the assembly efficiency of the water retaining member 33 and the second motor cover 32, ensuring the connection reliability of the water retaining member 33 and the second motor cover 32. Furthermore, the integrally formed structure has higher overall strength and stability and a longer service life.

[0059] According to some embodiments of the present invention, the first motor cover 31 is provided with a connecting buckle 312, the second motor cover 32 is provided with a connecting hole 321 that engages with the connecting buckle 312, the water retaining member 33 and the second motor cover 32 define a disassembly avoidance slot 34, and the disassembly avoidance slot 34 is open in a direction away from the first motor cover 31. The connecting buckle 312 includes an elastic arm 3121 and a snap-fitting protrusion 3122 of the elastic arm 3121. The elastic arm 3121 is inserted into the connecting hole 321, and the snap-fitting protrusion 3122 is located in the disassembly avoidance slot 34. In other words, the first motor cover 31 is snap-fitted to the second motor cover 32 through the snap-fitting connection between the connecting buckle 312 and the connecting hole 321, which can reduce the difficulty of assembling the first motor cover 31 and the second motor cover 32, thereby improving the assembly efficiency of the air conditioner 100. In addition, the snap-fit ​​protrusion 3122 is located in the disassembly avoidance groove 34. Therefore, when it is necessary to release the connection between the first motor cover 31 and the second motor cover 32, the disassembly tool can be inserted into the disassembly avoidance groove 34 from the side of the second motor cover 32 and the snap-fit ​​protrusion 3122 can be pushed to move so that the snap-fit ​​protrusion 3122 can be disengaged from the connecting hole 321, thereby reducing the difficulty of disassembling the second motor cover 32.

[0060] According to some embodiments of the present utility model, the water retaining member 33 includes a water retaining body 331 and a connecting portion 335. The water retaining body 331 is located directly above the connection between the first motor cover 31 and the second motor cover 32. The water retaining body 331 is connected to the second motor cover 32 via the connecting portion 335. The connecting portion 335 is located on a side of the elastic arm 3121 facing away from the snap-fit ​​protrusion 3122. The disassembly avoidance groove 34 is located on a side of the connecting portion 335 facing the elastic arm 3121. A snap-fit ​​avoidance groove 3351 is formed on the connecting portion 335. The snap-fit ​​avoidance groove 3351 is arranged opposite to the connecting clip 312. In other words, the snap-fit ​​protrusion 3122 is located on a side of the elastic arm 3121 facing away from the first motor cover 31, and the snap-fit ​​avoidance groove 3351 is used to avoid deformation of the connecting clip 312. Therefore, when it is necessary to insert the connecting clip 312 into the connecting hole 321 or release the clamping relationship between the connecting clip 312 and the connecting hole 321, the clamping protrusion 3122 moves toward the direction close to the first motor cover 31, which will drive the upper end of the elastic arm 3121 to deform toward the direction close to the first motor cover 31, so that the clamping protrusion 3122 can pass through the connecting hole 321. The clamp avoidance groove 3351 on the connecting part 335 can better avoid the deformation of the connecting clip 312 toward the first motor cover 31, so as to avoid the connecting part 335 interfering with the deformation of the connecting clip 312.

[0061] In a specific example, a first mating portion is formed at one end of the first motor cover 31 close to the second motor cover 32, and a connecting buckle 312 and a limiting protrusion 313 arranged along the circumference of the motor are formed on the first mating portion. The connecting buckle 312 includes an elastic arm 3121 and a clamping protrusion 3122. The elastic arm 3121 extends in the up and down directions. The clamping protrusion 3122 is arranged at the upper end of the elastic arm 3121 and is located on the side of the elastic arm 3121 facing the second motor cover 32. The limiting protrusion 313 extends in the up and down directions. The second motor cover 32 is formed with a second matching portion at one end close to the first motor cover 31, and the second matching portion is formed with a connecting hole 321 and a limiting hole 322 arranged along the circumference of the motor, and the connecting hole 321 and the limiting hole 322 both pass through the second matching portion in the up-down direction, wherein the connecting buckle 312 is snapped into engagement with the connecting hole 321 in the up-down direction, and the limiting protrusion 313 is plugged into engagement with the limiting hole 322 in the up-down direction, and the connecting portion 335 of the water-blocking component 33 is roughly perpendicular to the axial direction of the motor, and the connecting portion 335 is connected to one end of the second matching portion close to the first motor cover 31 and extends upward, and after the first motor cover 31 and the second motor cover 32 are assembled, the elastic arm 3121 is located on the side of the connecting portion 335 facing the second motor cover 32, and the water-blocking body 331 of the water-blocking component 33 is located at the top of the connecting portion 335 and is spaced apart from the connecting buckle 312 in the up-down direction.

[0062] According to some embodiments of the present invention, the water retaining component 33 includes a water retaining body 331, a first water retaining flange 332 and a connecting portion 335. The water retaining body 331 is located directly above the connection between the first motor cover 31 and the second motor cover 32. The first water retaining flange 332 is provided at one end of the water retaining body 331 close to the second motor cover 32 and extends upwardly. The water retaining body 331 is connected to the second motor cover 32 through the connecting portion 335. The disassembly avoidance groove 34 is located on the side of the connecting portion 335 facing the second motor cover 32, and in the up and down directions, the disassembly avoidance groove 34 is located between the first water retaining flange 332 and the second motor cover 32. Among them, since the first water-retaining flange 332 extends upwardly at an angle relative to the water-retaining body 331, the distance between the first water-retaining flange 332 and the connecting hole 321 in the vertical direction is increased in the direction from the first motor cover 31 to the second motor cover 32, thereby providing a larger operating space for the disassembly of the connecting clip 312, making it easier to release the clamping relationship between the connecting clip 312 and the connecting hole 321, so as to remove the second motor cover 32 from the first motor cover 31.

[0063] According to some embodiments of the present invention, the angle between the first water retaining flange 332 and the horizontal direction is not less than 45°. It is understood that the angle between the first water retaining flange 332 and the horizontal direction is proportional to the size of the space for disassembling the avoidance groove 34. That is, the larger the angle between the first water retaining flange 332 and the horizontal direction, the more space is available for disassembling the avoidance groove 34 to facilitate disassembly of the connecting clip 312. Therefore, by setting the angle between the first water retaining flange 332 and the horizontal direction to not less than 45°, the difficulty of disassembling the connecting clip 312 can be reduced. The angle between the first water retaining flange 332 and the horizontal direction can be 45°, 48°, 50°, 53°, 55°, 57°, 60°, 65°, etc., without specific limitation.

[0064] According to some embodiments of the present invention, a water pan is provided within the housing assembly, the water pan being located below the heat exchanger assembly 2, and the projection of the motor cover assembly 3 on the horizontal plane being located within the projection of the water pan on the horizontal plane. In other words, in the horizontal direction, the water pan can well cover the motor cover assembly 3, thereby allowing the water pan to catch condensed water flowing out of the motor cover assembly 3, such as condensed water dripping from the refrigerant connection pipe 22 caught by the water retaining member 33 and the first motor cover 31. Furthermore, the water pan can be connected to a drainage pipeline, so that condensed water from the mobile phone within the air conditioner 100 can be collected by the water pan and discharged through the drainage pipeline, thereby preventing residual liquid within the air conditioner 100 from generating bacteria or mud, thereby ensuring the cleanliness of the internal environment of the air conditioner 100.

[0065] According to some embodiments of the present invention, the housing assembly includes a chassis 1, on which a fan component, a heat exchanger assembly 2, and a motor cover assembly 3 are disposed. The motor cover assembly 3 and the chassis 1 together define a mounting cavity 35 for accommodating the motor. Thus, the motor cover assembly 3 can accommodate the motor by leveraging the structure of the chassis 1, thereby reducing the overall size of the motor cover assembly 3 and lowering its cost.

[0066] In a specific example, the axial directions of the motor and the wind wheel extend in the horizontal direction, and a duct structure located on one side of the installation cavity 35 is formed on the chassis 1. The wind wheel is arranged in the duct structure, and the heat exchanger 21 is located between the air inlet and the wind wheel. The refrigerant connecting pipe 22 is connected to one end of the heat exchanger 21 close to the installation cavity 35 and is located above the motor. In the circumferential direction of the motor, the rear end of the first motor cover 31 is connected to the rear side wall of the chassis 1, and the front end of the first motor cover 31 extends downward in a curved arc and is connected to the bottom wall of the chassis 1. The drainage channel 314 extends downward in a direction from back to front along the outer wall surface of the first motor housing, and the drain outlet 315 is formed at the front end of the first motor cover 31 and is connected to the water receiving tray.
