Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to an air conditioner. Background Technology

[0002] As people's living standards improve, air conditioners have gradually entered thousands of households, becoming an important household appliance. Air conditioners use a fan to drive indoor air in through the air inlet, where it exchanges heat with the heat exchanger before being exhausted back into the room through the air outlet, thus regulating the temperature. The heat exchanger is connected to the refrigerant via pipes to transport the refrigerant. These pipes are typically located above the motor. When the motor cover is constructed from multiple parts, condensation on the refrigerant pipes may flow through the joints to the motor, posing a risk of water damage. Therefore, improvements are needed. Summary of the Invention

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

[0039] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize 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 now be described with reference to the accompanying drawings.

[0041] like Figures 1 to 9 As shown, the air conditioner 100 according to an embodiment of the present invention includes: a casing assembly, a fan assembly, a heat exchanger assembly 2, and a motor cover assembly 3. The casing assembly has an air inlet and an air outlet. The fan assembly 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 drawing indoor air into the casing assembly through the air inlet, exchanging heat through the heat exchanger 21, and then discharging it into the indoor space through the air outlet, thus achieving temperature regulation of the indoor air.

[0042] The motor cover assembly 3 covers the outside of the motor, and at least a portion of the refrigerant connection 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-blocking component 33. The first motor cover 31 and the second motor cover 32 are independently formed and connected. At least a portion of the water-blocking component 33 is located directly above the connection between the first motor cover 31 and the second motor cover 32. That is, in the vertical direction, at least a portion of the water-blocking component 33 blocks the connection between the first motor cover 31 and the second motor cover 32 and the refrigerant connection pipe 22. It can be understood that during the operation of the air conditioner 100, if the air conditioner 100 is in cooling mode, the refrigerant temperature in the refrigerant connection pipe 22 is low, causing condensation to form on the refrigerant connection pipe 22. Therefore, when condensation occurs on the portion of the refrigerant connection pipe 22 directly above the connection between the first motor cover 31 and the second motor cover 32, and the condensation drips downwards under gravity, the water-blocking component 33, located directly above the connection between the first motor cover 31 and the second motor cover 32, can effectively prevent the condensation from dripping into the connection between the first motor cover 31 and the second motor cover 32. This prevents the condensation from passing through the gap between the first motor cover 31 and the second motor cover 32 and contacting the motor, thereby avoiding the risk of water immersion in the motor and other electrical components, and improving the stability of the air conditioner 100.

[0043] According to an embodiment of the present invention, the air conditioner 100 can effectively prevent condensed water from dripping into the connection between the first motor cover 31 and the second motor cover 32 by the water-blocking component 33 located directly above the connection between the first motor cover 31 and the second motor cover 32. This prevents the condensed water from passing through the gap between the first motor cover 31 and the second motor cover 32 and coming into contact with the motor, thereby avoiding the risk of water immersion in the motor and other live components and improving the stability of the air conditioner 100.

[0044] According to some embodiments of the present invention, the water-blocking component 33 includes a water-blocking body 331, which is located directly above the connection between the first motor cover 31 and the second motor cover 32. A first water-blocking flange 332 extending upwards is formed on the edge of the water-blocking body 331 away from the first motor cover 31, and the edge of the water-blocking body 331 away from the first water-blocking flange 332 forms a drainage side. That is, the water-blocking body 331 can effectively catch condensed water dripping directly above the connection between the first motor cover 31 and the second motor cover 32. The first water-blocking flange 332 can prevent the condensed water falling on the water-blocking body 331 from flowing towards the second motor cover 32 on the side of the water-blocking body 331 away from the first motor cover 31. The condensed water falling on the water-blocking body 331 can flow along the water-blocking body 331 and through the side of the water-blocking body 331 away from the first water-blocking flange 332, i.e., the drainage side, towards the first motor cover 31. Therefore, the first water-blocking flange 332 can effectively limit the flow direction of condensed water on the water-blocking body 331, while the drainage side can prevent condensed water from staying on the water-blocking component 33. This can prevent condensed water from accumulating on the water-blocking body 331 and overflowing from the water-blocking component 33, thereby preventing the overflowing water from flowing down the water-blocking 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 side of the first motor cover 31 facing away from the motor. The drainage channel 314 can be connected to the structure of the air conditioner 100, such as the water tray, to drain condensate through the drain outlet 315. Since part of the refrigerant connection pipe 22 is located directly above the first motor cover 31, the drainage channel 314 can catch the condensate dripping from the refrigerant connection pipe 22 above. Furthermore, the condensate falling on the water baffle 33 can enter the drainage channel 314 through the drainage side and further drain into the water tray through the drain outlet 315 to prevent the condensate from staying on the motor cover assembly 3.

[0046] According to some embodiments of the present invention, a water-blocking rib 311 is formed on the edge of the first motor cover 31 near the second motor cover 32, and the water-blocking body 331 is located above the water-blocking rib 311, with the drainage side located on the side of the water-blocking rib 311 away from the second motor cover 32. Thus, the water-blocking rib 311 can prevent condensate falling on the first motor cover 31 from flowing towards the second motor cover 32, thereby preventing condensate from entering the connection between the first motor cover 31 and the second motor cover 32. That is, the water-blocking rib 311 can prevent condensate falling on the first motor cover 31 from overflowing, and allows the condensate 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, ensuring the stability of the motor cover assembly 3 in guiding the condensate out.

[0047] According to some embodiments of the present invention, the water-blocking component 33 further includes a flow-guiding flange 333 disposed on the drainage side and extending downward. The flow-guiding flange 333 is located on the side of the water-blocking rib 311 away from the second motor cover 32, and the lower end of the flow-guiding flange 333 is located below the upper end of the water-blocking rib 311. That is, when the condensed water falling on the water-blocking body 331 flows towards the first motor cover 31 through the drainage side, it will flow downward along the side of the flow-guiding flange 333 away from the water-blocking rib 311 and eventually flow onto the first motor cover 31. This can avoid the risk of water leakage caused by the condensed water flowing to the discharge side and flowing through the gap between the water-blocking body 331 and the water-blocking rib 311 to the side of the water-blocking rib 311 facing the second motor cover 32.

[0048] In some embodiments, the side of the guide flange 333 facing the water-blocking rib 311 is formed as a guide surface 3331. In the direction from the fixed end to the free end of the guide flange 333, the guide surface 3331 extends obliquely away from the water-blocking rib 311, thereby providing good guidance for the assembly of the water-blocking component 33 and reducing the assembly difficulty between the water-blocking component 33 and the first motor cover 31. In a specific example, the water-blocking 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 is formed between the guide flange 333 and the connecting portion 335 located on the lower side of the water-blocking body 331, and at least a portion of the water-blocking 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-blocking rib 311 is greater than 5 mm. Since the size of condensed water droplets is typically around 5 mm, controlling the vertical distance between the lower end of the guide flange 333 and the upper end of the water-blocking rib 311 to be greater than 5 mm can prevent condensed water droplets from flowing through the gap between the guide flange 333 and the water-blocking rib 311 to the side of the water-blocking 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-blocking 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., and is not specifically limited here.

[0050] According to some embodiments of the present invention, the water-blocking body 331 extends downwardly at an angle from the first water-blocking flange 332 to the drainage side. Therefore, the condensed water on the water-blocking body 331 can flow autonomously towards the drainage side under its own weight, thereby preventing the condensed water from staying on the water-blocking body 331 and accelerating the efficiency of the condensed water leaving the water-blocking component 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-blocking flange 332 of the water-blocking body 331 extends along the circumferential direction of the motor. 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 approximately arranged along the circumferential direction of the motor. Therefore, by extending the first water-blocking flange 332 of the water-blocking body 331 along the circumferential direction of the motor, the dimensions of the water-blocking body 331 and the first water-blocking flange 332 in the circumferential direction of the motor can be significantly increased. This increases the shielding area of ​​the water-blocking body 331 at the connection point of the first motor cover 31 and the second motor cover 32 in the circumferential direction of the motor. Simultaneously, it ensures that the first water-blocking flange 332 can completely cover the water-blocking body 331 in the circumferential direction of the motor, preventing condensation on the water-blocking body 331 from flowing to the second motor cover 32, thereby improving the reliability of the water-blocking component 33.

[0052] According to some embodiments of the present invention, the water-blocking body 331 has a first end and a second end at its two ends in the circumferential direction of the motor. In the direction from the first end to the second end, the water-blocking body 331 extends downward at an incline. A second water-blocking flange 334 extending upward is formed on the second end, and the second water-blocking flange 334 is connected to the first water-blocking flange 332. That is to say, the condensed water on the water-blocking body 331 can flow towards the second end under its own weight. The second water-blocking flange 334 can prevent the condensed water from flowing through the second end to the connection between the first motor cover 31 and the second motor cover 32. At the same time, the condensed water flowing to the second end can flow towards the first motor cover 31 along the second water-blocking flange 334. Thus, the drainage efficiency of the condensed water on the water-blocking body 331 can be improved, while the condensed water can flow steadily towards the first motor cover 31.

[0053] In a specific example, the guide flange 333 has a third water-blocking flange 336 formed at the end of the motor near the second end in the circumferential direction. The third water-blocking flange 336 flows along the axial direction of the motor in a direction away from the water-blocking rib 311, and the upper end of the third water-blocking flange 336 is connected to the end of the second water-blocking flange 334 away from the first water-blocking flange 332. Thus, the first water-blocking flange 332, the second water-blocking flange 334 and the third water-blocking flange 336 can form a continuous water-blocking structure to ensure that the condensate on the water-blocking 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 periphery of the motor, and the second motor cover 32 is located on the side of the motor away from the impeller. That is, the first motor cover 31 can protect and fix the motor from the outer periphery 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 away from the impeller. This can ensure the protective performance of the motor cover assembly 3 for 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 shield the motor, so that the first motor cover 31 is located directly below most of the refrigerant connection pipe 22. This allows the first motor cover 31 to catch most of the condensate dripping from the refrigerant connection pipe 22. Therefore, only the drainage channel 314 needs to be provided on the first motor cover 31, eliminating the need for drainage structures such as the drainage channel 314 on the second motor cover 32. Furthermore, since the second motor cover 32 is located on the side of the motor away from the impeller, when it is necessary to remove the motor, the motor can be pulled out from the second motor cover 32 after removing the second motor cover 32. Compared with the first motor cover 31, which has a refrigerant connection pipe 22 arranged above it, the operating space on the side of the motor away from the impeller is larger, which can reduce the difficulty of disassembling the motor.

[0055] According to some embodiments of the present invention, the housing assembly has a clearance opening 11 located on the outer periphery of the fan. The refrigerant connection pipe 22 extends out of the housing assembly through the clearance opening 11. In the axial direction of the motor, the first water-blocking flange 332 is located on the side of the clearance opening 11 away from the impeller. It is understood that during the installation of the air conditioner 100, when the installer adjusts the position of the refrigerant connection pipe 22 on the outer part of the housing assembly, the refrigerant connection pipe 22 inside the housing assembly may be shifted. However, due to the limitation of the inner peripheral wall of the clearance opening 11, the displacement of the refrigerant connection pipe 22 is controlled within the coverage area of ​​the clearance opening 11, that is, the refrigerant connection pipe 22 cannot shift to the side of the clearance opening 11 away from the impeller. Therefore, by setting the first water-blocking flange 332 on the side of the relief opening 11 away from the wind turbine, even if the refrigerant connection pipe 22 is offset to the edge of the relief opening 11 away from the wind turbine, the water-blocking component 33 can still catch the condensate dripping from the refrigerant connection pipe 22, so as to ensure the reliability of the water-blocking component 33.

[0056] According to some embodiments of the present invention, the first water-blocking flange 332 protrudes from the water-blocking body 331 by a height greater than 5 mm. Since the size of condensed water droplets is typically around 5 mm, by ensuring the height of the first water-blocking flange 332 protruding from the water-blocking body 331 is greater than 5 mm, condensed water can be prevented from overflowing the first water-blocking flange 332 and flowing to the side of the first water-blocking flange 332 facing the second motor cover 32. The height of the first water-blocking flange 332 protruding from the water-blocking 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, etc., and no specific limitation is made here.

[0057] According to some embodiments of the present invention, the water-blocking component 33 is disposed on the second motor cover 32. Thus, the connection between the water-blocking component 33 and the second motor cover 32 effectively maintains the position between them; that is, the relative position between the water-blocking component 33 and the second motor cover 32 remains fixed. This allows the water-blocking component 33 to be stably maintained at least partially above the connection between the first motor cover 31 and the second motor cover 32, ensuring the reliability of the water-blocking function of the water-blocking component 33.

[0058] According to some embodiments of the present invention, the water-blocking component 33 and the second motor cover 32 are integrally formed. Therefore, the integrally formed structure not only ensures the structural and performance stability of the water-blocking component 33 and the second motor cover 32, but also facilitates molding and simplifies manufacturing. Furthermore, it eliminates the need for assembly parts and connection processes used to connect the water-blocking component 33 and the second motor cover 32, resulting in lower production costs and significantly improved assembly efficiency. This ensures reliable connection between the water-blocking component 33 and the second motor cover 32. Moreover, the integrally formed structure has higher overall strength and stability, and a longer service life.

[0059] According to some embodiments of the present invention, a connecting buckle 312 is provided on the first motor cover 31, and a connecting hole 321 is provided on the second motor cover 32 to engage with the connecting buckle 312. The water-blocking component 33 and the second motor cover 32 define a disassembly clearance groove 34, which opens away from the first motor cover 31. The connecting buckle 312 includes an elastic arm 3121 and a snap-fit ​​protrusion 3122 of the elastic arm 3121. The elastic arm 3121 passes through the connecting hole 321, and the snap-fit ​​protrusion 3122 is located within the disassembly clearance groove 34. In other words, the first motor cover 31 is snapped together with the second motor cover 32 through the engaging engagement of the connecting buckle 312 and the connecting hole 321, which can reduce the assembly difficulty of the first motor cover 31 and the second motor cover 32 and improve the assembly efficiency of the air conditioner 100. Furthermore, since the snap-fit ​​protrusion 3122 is located within the disassembly clearance groove 34, when it is necessary to disconnect the connection between the first motor cover 31 and the second motor cover 32, a disassembly tool can be inserted into the disassembly clearance groove 34 from one 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 connection hole 321, which can reduce the difficulty of disassembling the second motor cover 32.

[0060] According to some embodiments of the present invention, the water-blocking component 33 includes a water-blocking body 331 and a connecting portion 335. The water-blocking body 331 is located directly above the connection between the first motor cover 31 and the second motor cover 32. The water-blocking body 331 is connected to the second motor cover 32 through the connecting portion 335. The connecting portion 335 is located on the side of the elastic arm 3121 opposite to the snap-fit ​​protrusion 3122. The disassembly clearance groove 34 is located on the side of the connecting portion 335 facing the elastic arm 3121. A snap-fit ​​clearance groove 3351 is formed on the connecting portion 335, and the snap-fit ​​clearance groove 3351 is disposed opposite to the connecting snap-fit ​​312. That is, the snap-fit ​​protrusion 3122 is located on the side of the elastic arm 3121 opposite to the first motor cover 31, and the snap-fit ​​clearance groove 3351 is used to avoid deformation of the connecting snap-fit ​​312. Therefore, when it is necessary to insert the connecting buckle 312 into the connecting hole 321 or to release the connection between the connecting buckle 312 and the connecting hole 321, the snap-fit ​​protrusion 3122 will move toward the direction closer to the first motor cover 31, which will cause the upper end of the elastic arm 3121 to deform toward the direction closer to the first motor cover 31, so that the snap-fit ​​protrusion 3122 can pass through the connecting hole 321. The buckle relief groove 3351 on the connecting part 335 can better avoid the deformation of the connecting buckle 312 toward the first motor cover 31, so as to avoid the connecting part 335 interfering with the deformation of the connecting buckle 312.

[0061] In a specific example, a first mating part is formed at one end of the first motor cover 31 near the second motor cover 32. A connecting buckle 312 and a limiting protrusion 313 are formed on the first mating part along the circumference of the motor. The connecting buckle 312 includes an elastic arm 3121 and a locking protrusion 3122. The elastic arm 3121 extends in the vertical direction. The locking protrusion 3122 is located at the upper end of the elastic arm 3121 and on the side of the elastic arm 3121 facing the second motor cover 32. The limiting protrusion 313 extends in the vertical direction. The second motor cover 32 has a second mating part formed at one end near the first motor cover 31. The second mating part has a connecting hole 321 and a limiting hole 322 arranged along the circumference of the motor. Both the connecting hole 321 and the limiting hole 322 pass through the second mating part in the vertical direction. The connecting buckle 312 engages with the connecting hole 321 in the vertical direction, and the limiting protrusion 313 engages with the limiting hole 322 in the vertical direction. The connecting part 335 of the water-blocking component 33 is approximately perpendicular to the axial direction of the motor. The connecting part 335 is connected to the end of the second mating part near the first motor cover 31 and extends upward. 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 part 335 facing the second motor cover 32. The water-blocking body 331 of the water-blocking component 33 is located at the top of the connecting part 335 and is spaced apart from the connecting buckle 312 in the vertical direction.

[0062] According to some embodiments of the present invention, the water-blocking component 33 includes a water-blocking body 331, a first water-blocking flange 332, and a connecting portion 335. The water-blocking body 331 is located directly above the connection between the first motor cover 31 and the second motor cover 32. The first water-blocking flange 332 is disposed at one end of the water-blocking body 331 near the second motor cover 32 and extends upward at an incline. The water-blocking body 331 is connected to the second motor cover 32 through the connecting portion 335. The disassembly clearance groove 34 is located on the side of the connecting portion 335 facing the second motor cover 32, and in the vertical direction, the disassembly clearance groove 34 is located between the first water-blocking flange 332 and the second motor cover 32. As the first water-blocking flange 332 extends upward relative to the water-blocking body 331, the vertical distance between the first water-blocking flange 332 and the connecting hole 321 increases in the direction from the first motor cover 31 to the second motor cover 32. This provides more operating space for disassembling the connecting buckle 312, making it easier to release the connection between the connecting buckle 312 and the connecting hole 321, so that the second motor cover 32 can be removed 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 directly proportional to the size of the disassembly clearance groove 34; that is, the larger the angle between the first water-retaining flange 332 and the horizontal direction, the larger the space that the disassembly clearance groove 34 can have to facilitate the disassembly of the connecting clip 312. Therefore, by ensuring that the angle between the first water-retaining flange 332 and the horizontal direction is 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., and no specific limitation is made here.

[0064] According to some embodiments of the present invention, a water collection tray is provided inside the housing assembly, located below the heat exchanger assembly 2, and the projection of the motor cover assembly 3 on the horizontal plane lies within the projection of the water collection tray on the horizontal plane. In other words, in the horizontal direction, the water collection tray can effectively cover the motor cover assembly 3, thereby allowing the water collection tray to catch condensate flowing out from the motor cover assembly 3, such as the condensate dripping from the refrigerant connection pipe 22 caught by the water baffle 33 and the first motor cover 31. Furthermore, the water collection tray can be connected to a drain pipe, so that the condensate inside the air conditioner 100 can be collected through the water collection tray and discharged through the drain pipe, preventing bacteria or dirt from forming from residual liquid inside the air conditioner 100, thus 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, a fan component, a heat exchanger assembly 2, and a motor cover assembly 3, all disposed on the chassis 1. The motor cover assembly 3 and the chassis 1 together define a mounting cavity 35 for accommodating the motor. This allows the motor cover assembly 3 to accommodate the motor using the structure on the chassis 1, reducing the overall size of the motor cover assembly 3 and lowering operating costs.

[0066] In a specific example, the motor and the impeller extend axially in the horizontal direction. A duct structure is formed on the chassis 1 on one side of the mounting cavity 35. The impeller is located in the duct structure. The heat exchanger 21 is located between the air inlet and the impeller. The refrigerant connection pipe 22 is connected to the end of the heat exchanger 21 near the mounting cavity 35 and 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. 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 backward-to-forward direction along the outer wall of the first motor housing. The drain outlet 315 is formed at the front end of the first motor cover 31 and communicates with the water receiving tray.
