Description

Technical Field

[0001] This application relates to the field of home appliance technology, such as a motion component, a de-icing device, and an air conditioner. Background Technology

[0002] Air conditioners are now widely used in people's daily lives. When an air conditioner is in heating mode, the refrigerant first passes through the compressor to become a high-pressure gas, and then condenses and releases heat in the indoor heat exchanger to become a high-pressure liquid refrigerant. This high-pressure liquid refrigerant then passes through a throttling device to become a low-temperature, low-pressure liquid refrigerant, before evaporating and absorbing heat in the outdoor heat exchanger, and finally flows back to the compressor. Therefore, when the outdoor temperature is low and the air conditioner is in heating mode, not only is the outdoor heat exchanger prone to icing, but ice can also easily form on the outdoor unit casing and at the corresponding locations on the outdoor heat exchanger, affecting the air conditioner's efficiency.

[0003] Current air conditioners typically use reverse cooling to defrost the outdoor heat exchanger. This involves changing the air conditioner's operating mode using a four-way reversing valve, causing the outdoor heat exchanger to generate hot air that melts the ice on it. At the same time, the hot air can also heat the ice on the outer casing of the outdoor unit, thus achieving a certain degree of defrosting.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Existing air conditioners that use reverse cooling to defrost have limited effectiveness in removing ice buildup on the outdoor unit casing.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0047] like Figures 1 to 14 As shown, this embodiment of the disclosure provides a motion component that can be fitted with a de-icing component and drive the de-icing component to reciprocate in a preset motion direction, including a first pulley group, a second pulley group, and a drive motor. The first pulley group includes a plurality of first pulleys 21 disposed on a first side motion section 12 parallel to the preset motion direction and a first transmission belt 22 sleeved on the plurality of first pulleys 21, as shown. Figure 9 As shown; the second pulley group includes a plurality of second pulleys 23 arranged along a first side movement section 12 and a second side movement section 13 parallel to a preset movement direction, and a second transmission belt 24 sleeved on the plurality of second pulleys 23, as shown. Figure 9 As shown, the drive motor is connected to at least one first pulley 21 and at least one second pulley 23, which can drive the first pulley 21 and the second pulley 23 to rotate synchronously in the forward or reverse direction, thereby driving the first transmission belt 22 and the second transmission belt 24 to move in the forward or reverse direction, realizing reciprocating motion in a preset motion direction. The first side motion range 12 and the second side motion range 13 are arranged opposite to each other.

[0048] Specifically, the first transmission belt 22 and the second transmission belt 24 are respectively fitted onto a plurality of first pulleys 21 and second pulleys 23, and both the first transmission belt 22 and the second transmission belt 24 are in a taut state. The output end of the drive motor 25 can drive the first pulleys 21 and the second pulleys 23 to rotate, thereby driving the first transmission belt 22 and the second transmission belt 24 to move, and the first transmission belt 22 and the second transmission belt 24 move at the same speed.

[0049] It is understood that in the first pulley group, a first-direction transmission section and a second-direction transmission section are formed between the two first pulleys at both ends of the first side movement section 12, wherein the second-direction transmission section is located on the side closer to the second side movement section 13; in the second pulley group, a first-direction transmission section is formed between the two second pulleys at both ends of the first side movement section 12, and a second-direction transmission section is formed between the two second pulleys at both ends of the second side movement section 13; the transmission between the second-direction transmission section of the first pulley group and the second-direction transmission section of the second pulley group realizes reciprocating motion in a preset movement direction.

[0050] like Figure 9As shown, in some practical applications, the preset motion area 11 is a square, including a first edge and a second edge arranged opposite to each other. A first motion zone is set on the outer side of the first edge, corresponding to the first edge, and a second motion zone is set on the outer side of the second edge, corresponding to the second edge. The first pulley group includes two first pulleys 21, which are respectively set at the first end and the second end of the first side motion zone 12. The second pulley group includes four second pulleys 23, which are respectively set at the first end of the first side motion zone 12 and the second end of the second side motion zone 13. The first pulleys 21 and 23 are of the same size, and when the first pulleys 21 and 23 rotate at the same speed, the first transmission belt 22 and the second transmission belt 24 also move at the same speed. The output end of the drive motor 25 is connected to the first pulleys 21 and 23 set at the first end of the first side motion zone 12, and can drive the first pulleys 21 and 23 to rotate in the same direction, thereby driving the first transmission belt 22 and the second transmission belt 24 to move in the same direction.

[0051] like Figure 3 and Figure 4 As shown, in some embodiments, the first transmission belt 22 includes a first connecting portion 221 near the second side movement zone 13; the second transmission belt 24 includes a second connecting portion 241 disposed in the second side movement zone 13. The first connecting portion 221 and the second connecting portion 241 are arranged opposite to and parallel to each other; the first connecting portion and the second connecting portion move synchronously in the forward or reverse direction, thereby driving the de-icing assembly to reciprocate in a preset movement direction.

[0052] Specifically, the first connecting portion 221 is not a fixed part of the first transmission belt 22, but rather the portion of the first transmission belt 22 located in the second direction of the first side movement range 12. For example, when the portion of the first transmission belt 22 located in the first direction of the first side movement range 12 moves with the pulley to the second direction of the second direction, this portion of the first transmission belt 22 can be referred to as the first connecting portion 221. Similarly, the second connecting portion 241 is the portion of the second transmission belt located in the second direction of the second side movement range 13. The first connecting portion 221 and the second connecting portion 241 move in the same direction and are parallel to each other with the first pulley 21 and the second pulley 23, respectively.

[0053] like Figure 9As shown, it can be understood that since the preset motion area 11 is set between the first side motion interval 12 and the second side motion interval, and multiple first pulleys 21 are all set in the first side motion interval 12, although the first connecting part 221 is the part of the first transmission belt 22 near the second edge, for the motion assembly as a whole, the first connecting part 221 is still in the first side motion interval 12, so that the preset motion area 11 is between the first connecting part 221 and the second connecting part 241.

[0054] like Figure 4 and Figure 5 As shown, in some embodiments, the second pulley 23 disposed on the first side movement zone 12 is configured in a one-to-one correspondence with the first pulley 21, and the corresponding first pulley 21 and second pulley 23 are coaxially configured through the connecting rod 29 to form a composite pulley; the drive motor 25 is connected to at least one composite pulley for transmission.

[0055] Specifically, the first pulley 21 and the second pulley 23 are provided with connecting holes at their axle centers for connection with the connecting rod 29. The second pulley 23, located in the first side movement zone 12, is coaxially mounted on the connecting rod 29 with the corresponding first pulley 21 to form a composite pulley. The first pulley 21 and the second pulley 23, located on the same connecting rod 29, are fixedly connected to the connecting rod 29 so that the connecting rod 29 can synchronously drive the first pulley 21 and the second pulley 23 to rotate in the forward or reverse direction.

[0056] like Figure 4 and Figure 5 As shown, in some embodiments, the aforementioned motion assembly further includes a driving pulley 26, a driven pulley 27, and a third transmission belt 28. The driving pulley 26 is connected to the output end of the drive motor 28; the driven pulley 27 is coaxially connected to the first pulley 21 and / or the second pulley 23; the third transmission belt 28 is sleeved on the driving pulley 26 and the driven pulley 27 for transmission between the driving pulley 26 and the driven pulley 27. The drive motor 25 can drive the driven pulley 27 to rotate via the driving pulley 26, thereby driving the first pulley 21 and the second pulley 23 to rotate, and further driving the first transmission belt 22 and the second transmission belt 24 to move; when the correspondingly arranged first pulley 21 and second pulley 23 are coaxially arranged to form a composite pulley via a connecting rod 29, the driven pulley 27 is coaxially arranged on the connecting rod 29.

[0057] Specifically, the driving pulley 26 is fixedly connected to the output end of the drive motor 25, and the driving pulley 26 and the drive motor 25 are coaxially arranged. The driven pulley 27 is connected to at least one first pulley 21 and at least one second pulley 23, and the driven pulley 27, the first pulley 21 and the second pulley 23 are coaxially arranged. The drive motor 25 can drive the driving pulley 26 to rotate, and then drive the driven pulley 27 to rotate through the third transmission belt 28. The driven pulley 27 then drives the first pulley 21 and the second pulley 23 to rotate synchronously. By having a set of driving pulleys 26 and driven pulleys 27 simultaneously drive the first pulley 21 and the second pulley 23 to rotate, the structure is simple and can ensure that the rotation speed of the first pulley 21 and the second pulley 23 is the same.

[0058] like Figure 5 As shown, in practical applications, the coaxially arranged first pulley 21, second pulley 23, driven pulley 27, and connecting rod 29 can be connected by welding or using fasteners, snap-fit ​​components, etc., simply by ensuring that the first pulley 21, second pulley 23, driven pulley 27, and connecting rod 29 are mutually fixed. Furthermore, the coaxially arranged first pulley 21, second pulley 23, and driven pulley 27 can be a three-layer pulley, or a combination of a double-layer pulley and a single-layer pulley, or three single-layer pulleys.

[0059] In some practical applications, the first pulley group includes two first pulleys 21, which are respectively located at the first end and the second end of the first side movement range 12; the second pulley group includes four second pulleys 23, which are respectively located at the first end of the first side movement range 12 and the second end of the second side movement range 13. The driven pulley 27 is connected to the first pulley 21 and the second pulley 23 located at the first end of the first side movement range 12, and the driven pulley 27, the first pulley 21, and the second pulley 23 are coaxially arranged. The drive motor 25 can drive the driven pulley 27 to rotate through the driving pulley 26, which in turn drives the first pulley 21 and the second pulley 23 to rotate. Then, the first pulley 21 drives the first transmission belt 22 to move and drives the other first pulleys 21 to rotate, and the second pulley 23 drives the second transmission belt 24 to move and drives the other second pulleys 23 to rotate.

[0060] Optionally, the aforementioned motion assembly further includes a driving gear and a driven gear. The driving gear is connected to the output end of the drive motor 25, and the driven gear is connected to the first pulley 21 and the second pulley 23, with the driving gear and the driven gear meshing together. The drive motor 25 can drive the driven gear to rotate via the driving gear, thereby driving the first pulley 21 and the second pulley 23 to rotate.

[0061] like Figure 6 and Figure 7As shown, in some practical applications, a connecting hole 211 is provided through the axis of the first pulley 21, and the connecting hole 211 is provided with a first snap-fit ​​structure 212. The connecting rod 29 is provided with a second snap-fit ​​structure 291 corresponding to the first snap-fit ​​structure 212. Similarly, the connecting holes 211 are provided through the axis of the second pulley 23 and the driven pulley 27, and the connecting holes 211 are both provided with a first snap-fit ​​structure 212. If the connecting rod 29 passes through the connecting holes 211 of the first pulley 21, the second pulley 23 and the driven pulley 27, the first pulley 21, the second pulley 23 and the driven pulley 27 can be snapped into the second snap-fit ​​structure 291 of the connecting rod 29 through the first snap-fit ​​structure 212, so that the first pulley 21, the second pulley 23 and the driven pulley 27 are snapped into the connecting rod 29 and are in a mutually fixed state.

[0062] like Figure 1 and Figure 2 As shown in the embodiments of this disclosure, a de-icing device is also provided, including a first motion component 20 and a second motion component 30. The first motion component 20 is capable of outputting motion in a first direction; the second motion component 30 is capable of outputting motion in a second direction, and the first direction and the second direction form a preset angle. The first motion component 20 and / or the second motion component 30 employ the aforementioned motion components; the first motion component 20 and the second motion component 30 are respectively capable of driving the de-icing component 40 to move in the first direction and the second direction, thereby enabling the de-icing component 40 to move within a preset motion area 11.

[0063] The motion structure provided in this application has the characteristics of simple structure, smooth transmission, buffering and vibration absorption, low cost, no need for lubrication and easy maintenance.

[0064] like Figure 1 and Figure 2 As shown, in some embodiments, the above-mentioned de-icing device further includes a de-icing component 40. The de-icing component 40 is connected to the first motion component 20 and the second motion component 30 respectively. The first motion component 20 can drive the de-icing component 40 to move in a first direction, and the second motion component 30 can drive the de-icing component 40 to move in a second direction. The first motion component 20 and the second motion component 30 cooperate to drive the de-icing component 40 to move within the preset motion area 11.

[0065] Specifically, the first motion component 20 can drive the de-icing component 40 to move in a first direction, and the second motion component 30 can drive the de-icing component 40 to move in a second direction. The first motion component 20 and the second motion component 30 cooperate to drive the de-icing component 40 to move within the preset motion area 11. In practical applications, the de-icing device is installed on other components that need de-icing, such as an outdoor unit of an air conditioner, and is arranged such that the preset operating area covers the preset de-icing area of ​​other components. If icing occurs in the preset de-icing area, the first motion component 20 first drives the de-icing component 40 to move in the first direction; the second motion component 30 then drives the de-icing component 40 to move in the second direction so that the de-icing component 40 moves to the icing area.

[0066] In the above embodiments, the angles of the first and second directions can be set according to the actual preset de-icing area, as long as the movement area of ​​the de-icing component 40 can cover the preset de-icing area. Specifically, in practical applications, the first movement component 20 can drive the de-icing component 40 to move a distance in the first direction greater than or equal to the height of the de-icing area, and the second movement component 30 can drive the de-icing component 40 to move a distance in the second direction greater than or equal to the width of the de-icing area. This configuration allows the first and second movement components 20 to drive the de-icing component 40 to move within the entire range of the preset de-icing area, avoiding blind spots within the preset de-icing area that the de-icing component 40 cannot reach.

[0067] Optionally, the first direction is defined as vertical, that is, the first motion component 20 can drive the de-icing component 40 to move vertically; the second direction is defined as horizontal, that is, the second motion component 30 can drive the de-icing component 40 to move horizontally.

[0068] In some embodiments, the de-icing assembly 40 includes a connector 41 and a de-icing element 42. The connector 41 is connected to the first motion assembly 20 and the second motion assembly 30, respectively; the de-icing element 42 is mounted on the connector 41 and is disposed toward a preset de-icing area.

[0069] Specifically, the first motion component 20 and the second motion component 30 are respectively connected to the connector 41. The first motion component 20 can drive the connector 41 to move in a first direction, thereby driving the de-icing element 42 to move in the first direction. The second motion component 30 can drive the connector 41 to move in a second direction, thereby driving the de-icing element 42 to move in the second direction. The de-icing element 42 is installed on the side of the connector 41 facing the preset de-icing area. When the first motion component 20 and the second motion component 30 drive the de-icing component 40 to move to the icing area, the de-icing element 42 can de-ic the icing area.

[0070] In some embodiments, the first motion component 20 and the second motion component 30 employ the motion components described above. When the first transmission belt 22 includes a first connecting portion 221 and the second transmission belt 24 includes a second connecting portion 241, the de-icing device further includes a first transmission rod 31 and a second transmission rod 32. The first transmission rod 31 passes through the connector 41 along a second direction, and its two ends are respectively connected to the first connecting portion 221 and the second connecting portion 241 of the first motion component 20. The second transmission rod 32 passes through the connector 41 along a first direction, and its two ends are respectively connected to the first connecting portion 221 and the second connecting portion 241 of the second motion component 30. The connector 41 is slidable along the first transmission rod 31 in the second direction and along the second transmission rod 32 in the first direction.

[0071] like Figure 2 and Figure 8 As shown, specifically, the connector 41 includes a first through hole 416 arranged along the second direction and a second through hole 417 arranged along the first direction. The first transmission rod 31 passes through the first through hole 416, and the second transmission rod 32 passes through the second through hole 417. The connecting part is slidably connected to the first transmission rod 31 and the second transmission rod 32. The movement speed and movement direction of the first connecting part 221 are the same as those of the second connecting part 241. The drive motor 25 of the first motion assembly 20 can drive the first pulley 21 and the second pulley 23 to rotate synchronously, thereby driving the first transmission belt 22 and the second transmission belt 24 to move in the same direction and speed. At this time, the first connecting part 221 and the second connecting part 241 of the first motion assembly 20 can simultaneously drive the two ends of the first transmission rod 31 to move in the first direction, thereby driving the connector 41 to move in the first direction. Similarly, the drive motor 25 of the second motion assembly 30 can drive the second pulley 23 to rotate synchronously, thereby driving the second transmission rod 32 and the connector 41 to move in the second direction through the first transmission belt 22 and the second transmission belt 24.

[0072] It is understandable that when the first motion assembly 20 drives the connecting member 41 to move in the first direction via the first transmission rod 31, the second transmission rod 32 will not interfere with the movement of the connecting member 41 in the first direction because the connecting member 41 can slide along the second transmission rod 32 in the first direction. Similarly, when the second motion assembly 30 drives the connecting member 41 to move in the second direction via the second transmission rod 32, the first transmission rod 31 will not interfere with the movement of the connecting member 41 in the second direction because the connecting member 41 can slide along the first transmission rod 31 in the second direction.

[0073] In some embodiments, the de-icing element 42 is an electric heating element; or, the de-icing element 42 is a blade assembly.

[0074] In some practical applications, the de-icing element 42 is an electrically heated element, and the de-icing device also includes a power supply electrically connected to the de-icing element 42 and a corresponding circuit. If the preset de-icing area is frozen, the first motion component 20 and the second motion component 30 can drive the de-icing component 40 to move to the frozen area, and the power supply supplies power to the de-icing element 42 so that it can generate heat and heat the frozen area to melt the ice.

[0075] In other practical applications, the de-icing element 42 is a blade assembly, which includes multiple blades with their blades facing a preset de-icing area. If the preset de-icing area is frozen, the first motion component 20 and the second motion component 30 can drive the de-icing element 40 to move back and forth repeatedly in the frozen area, so that the blade assembly scrapes off the ice in the frozen area.

[0076] In some embodiments, the de-icing device further includes a de-icing motor 51. The de-icing assembly 40 includes a connecting plate 41 with a limiting cylinder 412 and a de-icing element 42 inserted into the limiting cylinder 412; the de-icing motor 51 is mounted on the connecting plate 41 and includes an output end connected to the de-icing element 42 for driving the de-icing element 42 to rotate within the limiting cylinder 412. The limiting cylinder 412 and the de-icing element 42 are respectively provided with a first limiting structure 413 and a second limiting structure 45. When the de-icing element 42 rotates to a preset angle, the first limiting structure 413 can stop the second limiting structure 45.

[0077] Specifically, the limiting cylinder 412 is vertically disposed on the mounting side of the connecting plate 41. One end of the de-icing element 42 is inserted into the limiting cylinder 412, and the other end extends out of the limiting cylinder 412, with a blade provided at the end extending out of the limiting cylinder 412. The output end of the de-icing motor 51 is connected to the de-icing element 42 and is used to drive the de-icing element 42 to rotate circumferentially within the limiting cylinder 412. If the de-icing motor 51 drives the de-icing element 42 to rotate to a preset angle, the first limiting structure 413 disposed on the limiting cylinder 412 can stop the second limiting structure 45 disposed on the de-icing element 42, thereby stopping the de-icing element 42 from continuing to rotate.

[0078] If the outdoor unit of the air conditioner is covered in ice, the de-icing device can scrape the ice off the outdoor unit using the de-icing element 42 for targeted de-icing. The de-icing motor 51 can drive the de-icing element 42 to rotate within a preset angle to adjust the angle of the blade of the de-icing element 42. By driving the de-icing element 42 to rotate using the de-icing motor 51, the de-icing element 42 can scrape ice from multiple directions. Furthermore, the first limiting structure 413 and the second structure further limit the rotation angle of the de-icing element 42 to prevent it from rotating too far. This design improves the de-icing efficiency of the de-icing device.

[0079] In some practical applications, the de-icing element 42 and the de-icing motor 51 are mounted opposite each other on both sides of the connecting plate 41. One end of the de-icing element 42, inserted into the limiting cylinder 412, is provided with a connecting shaft 46, which extends from the axis of the de-icing element 42 towards the connecting plate 41. A clearance hole 414 is provided through the connecting plate 41 at the position corresponding to the connecting shaft 46. When the de-icing element 42 is installed inside the limiting cylinder 412, the connecting shaft 46 can pass through the clearance hole 414 and connect to the output end of the de-icing motor 51 located on the other side of the connecting plate 41. The de-icing motor 51 can drive the de-icing element 42 to rotate via the connecting shaft 46.

[0080] like Figures 8 to 10 As shown, in some embodiments, the first limiting structure 413 is a limiting opening provided on the wall of the limiting cylinder 412, and the second limiting structure 45 is a limiting protrusion provided on the de-icing element 42 at the position corresponding to the first limiting structure 413; or, the first limiting structure 413 is a limiting protrusion provided on the inner wall of the limiting cylinder 412, and the second limiting structure 45 is a limiting groove provided on the de-icing element 42 at the position corresponding to the first limiting structure 413.

[0081] Specifically, the de-icing motor 51 can drive the de-icing element 42 to rotate forward within the limiting cylinder 412, or it can drive the de-icing element 42 to rotate in reverse within the limiting cylinder 412. If the de-icing motor 51 drives the de-icing element 42 to rotate forward to its limit position, the first limiting structure 413 can stop the second limiting structure 45 to prevent the de-icing element 42 from continuing to rotate forward; similarly, if the de-icing motor 51 drives the de-icing element 42 to rotate in reverse to its limit position, the first limiting structure 413 can also stop the second limiting structure 45 to prevent the de-icing element 42 from continuing to rotate in reverse.

[0082] In some practical applications, a limiting opening is provided through the wall of the limiting cylinder 412 to form a first limiting structure 413, and a limiting protrusion is provided at the corresponding position of the de-icing element 42 to form a second limiting structure 45. When the de-icing element 42 is installed in the limiting cylinder 412, the limiting protrusion is located inside the limiting opening and can move within the limiting opening as the de-icing element 42 rotates. If the drive motor drives the de-icing element 42 to rotate forward to its limit position, the limiting protrusion abuts against the first edge of the limiting opening, at which point the limiting opening stops the limiting protrusion from continuing to move, thereby stopping the de-icing element 42 from rotating. If the de-icing motor 51 drives the de-icing element 42 to rotate in the opposite direction to its limit position, the limiting protrusion abuts against the second edge of the limiting opening to stop the de-icing element 42 from continuing to rotate. The first edge and the second edge are edges that are oppositely arranged on both sides of the limiting opening.

[0083] In other practical applications, the inner wall of the limiting cylinder 412 is provided with a limiting protrusion to form a first limiting structure 413, and a limiting groove is provided at the corresponding position of the de-icing element 42 to form a second limiting structure 45. When the de-icing element 42 is installed in the limiting cylinder 412, the limiting protrusion is located in the limiting groove. If the drive motor drives the de-icing element 42 to rotate forward to its limit position, the first wall of the limiting groove abuts against the limiting protrusion, at which point the limiting protrusion stops the limiting groove from continuing to move, thereby stopping the de-icing element 42 from rotating. If the de-icing motor 51 drives the de-icing element 42 to rotate in the opposite direction to its limit position, the second wall of the limiting groove abuts against the limiting protrusion to stop the de-icing element 42 from continuing to rotate. The first and second walls are walls that are oppositely located on both sides of the limiting groove.

[0084] In some embodiments, the preset angle of rotation of the de-icing element 42 is greater than or equal to 90° and less than or equal to 180°.

[0085] Specifically, the preset angle of rotation of the de-icing element 42 is greater than or equal to 90° and less than or equal to 180°, for example, it can be 90°, 120°, 150° or 180°.

[0086] In some practical applications, the preset rotation angle of the de-icing element 42 is 90°, and when the de-icing element 42 is in its initial state, its blade is horizontally positioned. With the blade horizontally positioned, the de-icing element 42 can move vertically within the icing area to scrape away ice. After the de-icing motor 51 drives the de-icing element 42 to rotate 90°, the first limiting structure 413 stops the second limiting structure 45 from continuing to rotate, at which point the blade of the de-icing element 42 is vertically positioned, and the de-icing element 42 can move horizontally within the icing area to scrape away ice.

[0087] It is understandable that the ice-scraping efficiency of the ice-removing element 42 is highest when the blade direction of the ice-removing element 42 is perpendicular to the direction of movement of the ice-removing element 42.

[0088] like Figure 10 As shown, in some embodiments, the de-icing element 42 includes a blade post 43 and a de-icing blade 44. The blade post 43 is inserted into the limiting cylinder 412 and includes a first end connected to the output end of the de-icing motor 51 and a second end disposed opposite to the first end; the de-icing blade 44 is disposed at the second end of the blade post 43.

[0089] Specifically, the second limiting structure 45 is positioned at the location corresponding to the first limiting structure 413 on the blade post 43. The blade post 43 has a receiving cavity 431, with the opening of the receiving cavity 431 located at the end of the blade post 43 facing the de-icing blade 44. The de-icing blade 44 includes a first end with a cutting edge and a second end opposite to the first end, the second end of which can be inserted into the receiving cavity 431 of the blade post 43. A connecting shaft 46 is located at the end of the blade post 43 facing the connecting plate 41, and the blade post 43 and the connecting shaft 46 are coaxially arranged. The de-icing motor 51 can drive the blade post 43 to rotate via the connecting shaft 46, thereby driving the de-icing blade 44 to rotate.

[0090] like Figure 12 As shown, optionally, a first snap-fit ​​structure 432 is provided in the receiving cavity 431 of the blade post 43, and a second snap-fit ​​structure 441 is provided corresponding to the first snap-fit ​​structure 432 for the portion of the de-icing blade 44 inserted into the receiving cavity 431. When the de-icing blade 44 is installed on the blade post 43, the first snap-fit ​​structure 432 can snap onto the second snap-fit ​​structure 441 to fix the de-icing blade 44 relative to the blade post 43. The de-icing motor 51 can drive the blade post 43 to rotate, thereby driving the de-icing blade 44 to rotate.

[0091] In some practical applications, the inner wall of the receiving cavity 431 is provided with a snap-fit ​​groove to form a first snap-fit ​​structure 432, and a snap-fit ​​protrusion is provided at the corresponding position of the de-icing blade 44 to form a second snap-fit ​​structure 441. When the de-icing blade 44 is installed in the receiving cavity 431, the snap-fit ​​protrusion snaps into the snap-fit ​​groove to fix the de-icing blade 44 and the blade post 43 relatively.

[0092] In other practical applications, the inner wall of the receiving cavity 431 is provided with a snap-fit ​​protrusion to form a first snap-fit ​​structure 432, and the corresponding position of the de-icing blade 44 is provided with a snap-fit ​​groove to form a second snap-fit ​​structure 441. When the de-icing blade 44 is installed in the receiving cavity 431, the snap-fit ​​protrusion snaps into the snap-fit ​​groove to fix the de-icing blade 44 and the blade post 43 relatively.

[0093] In some embodiments, the angle between the de-icing blade 44 and the connecting plate 41 is greater than or equal to 30° and less than or equal to 90°.

[0094] Specifically, the de-icing blade 44 is inclined on the connecting plate 41, and the de-icing blade 44 can be inclined upward or downward. The angle between the de-icing blade 44 and the connecting plate 41 can be 40°, 50°, 60°, 70° or 80°.

[0095] like Figure 10 and Figure 11 As shown, in some embodiments, the de-icing assembly 40 includes a plurality of de-icing elements 42, and the connecting plate 41 is provided with a plurality of limiting cylinders 412 corresponding to the de-icing elements 42.

[0096] Specifically, the connecting plate 41 is provided with multiple limiting cylinders 412, and each of the multiple limiting cylinders 412 is equipped with a corresponding de-icing element 42. The multiple de-icing elements 42 can simultaneously scrape ice from the icing area.

[0097] In some practical applications, the connecting plate 41 is evenly provided with four limiting cylinders 412, and the de-icing element 42 is installed in the four limiting cylinders 412 respectively. The limiting cylinders 412 in the upper part and the limiting cylinders 412 in the lower part are symmetrical, and the limiting cylinders 412 in the left part and the limiting cylinders 412 in the right part are symmetrical.

[0098] In other practical applications, the connecting plate 41 is evenly provided with five limiting cylinders 412, and the de-icing element 42 is installed in the five limiting cylinders 412 respectively. Among them, one limiting cylinder 412 is located at the symmetrical center of the connecting plate 41, and the other four limiting cylinders 412 are respectively located in the upper left, lower left, upper right and lower right parts of the connecting plate 41. The limiting cylinders 412 located in the upper half and the limiting cylinders 412 located in the lower half are symmetrical, and the limiting cylinders 412 located in the left half and the limiting cylinders 412 located in the right half are symmetrical.

[0099] like Figure 13 As shown, in some embodiments, the above-mentioned de-icing device further includes a gear set, which includes a driving gear 52 and a driven gear 53. The driving gear 52 is disposed at the output end of the de-icing motor 51; the driven gear 53 is disposed at the de-icing element 42 and meshes with the driving gear 52.

[0100] Specifically, the driving gear 52 is fixedly mounted on the output end of the de-icing motor 51, and the driving gear 52 and the output end of the de-icing motor 51 are coaxially arranged. The driven gear 53 is fixedly mounted on the connecting shaft 46 of the cutter post 43 at the position corresponding to the driving gear 52, and the cutter post 43, the connecting shaft 46, and the driven gear 53 are coaxially arranged. The driving gear 52 and the driven gear 53 mesh, and the de-icing motor 51 can drive the driven gear 53 to rotate through the driving gear 52, thereby driving the cutter post 43 to rotate.

[0101] like Figure 13 As shown, in some embodiments, when the de-icing assembly 40 includes multiple de-icing elements 42, the gear set is provided with multiple driven gears 53 corresponding to the de-icing elements 42, and the multiple driven gears 53 are respectively meshed with the driving gear 52.

[0102] Specifically, the gear set and the de-icing element 42 are provided with multiple driven gears 53, which are coaxially arranged with multiple cutter posts 43. The multiple driven gears 53 mesh with the driving gear 52 respectively, and there are gaps between the driven gears 53 to avoid interference between the driven gears 53 in rotation.

[0103] like Figure 13 As shown, in some practical applications, the connecting plate 41 is evenly provided with four limiting cylinders 412, and the de-icing element 42 is installed in the four limiting cylinders 412. Each limiting hole is provided with a clearance hole 414, and a connecting shaft 46 is provided at one end of the cutter post 43 corresponding to the clearance hole 414, with the connecting shaft 46 passing through the clearance hole 414 to the other side of the connecting plate 41. The gear set includes four driven gears 53, which are respectively disposed on the connecting shafts 46 of the four cutter posts 43, and are coaxially arranged with the four cutter posts 43 and the connecting shafts 46.

[0104] This disclosure also provides an air conditioner including a housing 10 and the aforementioned de-icing device. The housing 10 has a preset de-icing area that needs to be de-iced; the aforementioned de-icing device is configured such that the preset movement area 11 of the de-icing component 40 of the de-icing device covers the preset de-icing area, so that the de-icing component 40 can de-ic the preset de-icing area during its movement within the preset movement area 11.

[0105] Specifically, the first moving component 20 and the second moving component 30 can be fixed to the housing 10 by fasteners such as bolts, or can be detachably mounted to the housing 10 by connectors such as snap-fit ​​components. In an air conditioner using the de-icing component 40 provided in this application, if ice forms in a preset de-icing area, the de-icing component 40 can specifically de-ic the iced area, improving the de-icing efficiency of the air conditioner.

[0106] In the above embodiments, the positions of the first motion component 20 and the second motion component 30 can be set according to actual needs.

[0107] In some practical applications, the preset de-icing area is a square, the preset motion area 11 is a square corresponding to the preset de-icing area, and the preset motion area 11 can cover the preset de-icing area.

[0108] In other practical applications, the preset de-icing area is circular, the preset motion area 11 is a square corresponding to the circumscribed square of the preset de-icing area, and the preset motion area 11 can cover the preset de-icing area.

[0109] In practical applications, when the air conditioner is in heating mode and the temperature is low, there is a high probability that ice will form on the outdoor unit casing 10 corresponding to the heat exchanger. In this case, the area corresponding to the heat exchanger of the outdoor unit casing 10 can be set as a preset de-icing zone. When the de-icing device is installed on the outdoor unit of the air conditioner, the de-icing component 40 can move within the preset movement area 11, which can cover the preset de-icing zone.

[0110] The foregoing description and accompanying drawings fully illustrate embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the order of operation may vary. Parts and features of some embodiments may be included or substituted for parts and features of other embodiments.

The scope of the present disclosure is limited only by the appended claims.
