Description

Technical Field

[0001] The present application relates to the field of motor technology, and in particular to a motor structure and an air conditioner. Background Art

[0002] Because the air conditioner's outdoor unit is exposed to the elements for extended periods, rainwater and sand can enter the motor through the motor clamps. Once this sand enters the motor, it accumulates, causing friction between the rotor and stator, generating heat. This can eventually damage the motor, causing it to burn out and stop rotating, reducing product reliability.

[0003] Therefore, the current technology still needs to be improved and enhanced. Utility Model Content

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features indicated. The features specified as "first" and "second" may explicitly or implicitly include one or more features. In the description of this utility model, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0040] See also Figure 1 and Figure 2 The present embodiment provides a motor structure 1, which includes a rotor 10, a motor end cover 20, and a motor body 30; a first bearing 11 is provided at the first end of the opposite ends of the rotor 10, and a second bearing 12 is provided at the second end of the opposite ends of the rotor 10; the motor end cover 20 covers the first bearing 11, and the motor body 30 covers the second bearing 12, and forms an accommodation space between the motor end cover 20 and the motor body 30. In the embodiment of the present application, the motor body 30 is a BMC plastic-encapsulated motor. The winding pins 40 in the motor body 30 are located in the accommodation space and are connected to the motor leads 50; the number of the motor leads 50 is multiple.

[0041] In a specific embodiment, a wire outlet channel 60 is formed on one side of the motor body 30 close to the motor end cover 20 and opposite to the motor end cover 20. The wire outlet channel 60 is connected to the accommodating space, so that the motor lead 50 is led out along the corresponding wire outlet channel 60. Then, a wire outlet channel 60 is provided between the lead-out side of the motor lead 50 and the side of the winding pin 40 located inside the motor. The setting of the wire outlet channel 60 is equivalent to forming a buffer section between the outside of the motor and the inside of the motor, preventing sand or other debris outside the motor from directly entering the interior of the motor structure 1, and preventing the debris from accumulating for a long time and causing friction and damage to the rotor 10 inside the motor and the stator in the motor body 30, thereby improving the reliability of the motor structure 1.

[0042] Please also refer to Figure 3 and Figure 4In some embodiments, the outlet channel 60 is curved, meaning that the inner wall of the outlet channel 60 in the embodiments of the present application is a curved surface. Similarly, the curved wall of the outlet channel 60 can block external debris or sand from the motor structure 1, preventing the accumulation of debris over time from causing friction and damage to the rotor 10 and the stator in the motor body 30, thereby improving the reliability of the motor structure 1.

[0043] Please also refer to Figure 5 、 Figure 6 、 Figure 7 and Figure 8 In some embodiments, the outlet channel 60 includes a plurality of wiring cavity segments connected in sequence, and two adjacent wiring cavity segments are arranged tilted or vertically. In the embodiment of the present application, the outlet channel 60 is provided with a plurality of wiring cavity segments, and the adjacent wiring cavity segments are tilted (such as Figure 5 and Figure 6 As shown), adjacent wiring cavity sections can also be set vertically (as shown Figure 7 and Figure 8 As shown, the outlet channel 60 is curved, which can block external debris or sand from the motor structure 1. This prevents the long-term accumulation of debris from causing friction and damage between the rotor 10 inside the motor and the stator in the motor body 30, thereby improving the reliability of the motor structure 1. In some embodiments, the motor end cover 20 includes a cover portion 21 and a first extension portion 22 connected to the cover portion 21; the motor body 30 includes a main body 31 and a second extension portion 32 connected to the main body 31; the first extension portion 22 and the second extension portion 32 are both curved and spaced apart from each other to form the outlet channel 60. In the embodiment of the present application, the first extension portion 22 is formed by extending the covering portion 21, and the second extension portion 32 is formed by extending the main portion 31 of the motor body 30 outward. The first extension portion 22 and the second extension portion 32 are adapted to form a bent wire outlet channel 60. The setting of the wire outlet channel 60 is equivalent to forming a buffer section between the outside and the inside of the motor, preventing sand or other debris outside the motor from directly entering the interior of the motor structure 1, and preventing the debris from accumulating for a long time and causing friction and damage to the rotor 10 inside the motor and the stator in the motor body 30, thereby improving the reliability of the motor structure 1.

[0044] Please continue reading Figure 7 and Figure 8In some embodiments, the inlet of the outlet channel 60 is staggered with the outlet of the outlet channel 60, and the inlet of the outlet channel 60 is close to the motor end cover, while the outlet of the outlet channel 60 is close to the motor body. That is, in this embodiment, the inlet of the outlet channel 60 is close to one side of the rotor 10, and the outlet of the outlet channel 60 is relatively far from the side of the rotor. Then, along the direction of the rotor 10, the inlet of the outlet channel 60 and the outlet of the outlet channel 60 are staggered, that is, the inlet of the outlet channel 60 is close to the motor end cover 20, and the outlet of the outlet channel 60 is close to the motor body 30. Then, in the direction from the motor body 30 to the motor end cover 20, the inlet of the outlet channel 60 is higher than the outlet of the outlet channel 60, so that a certain height difference is formed between the inlet and outlet of the outlet channel 60. Then, when external sand or other debris enters through the outlet of the outlet channel 60, it is not easy to enter the interior of the motor structure through the inlet of the outlet channel 60, thereby further improving the reliability of the motor structure.

[0045] In some embodiments, the wall surface of the outlet channel 60 formed on the side of the motor body 30 is provided with a through hole 33; for example, one or more through holes 33 are provided in the second extension portion 32 to increase the position of the through hole relative to the motor (when the air conditioner is standing), for example, in combination with Figure 7 and Figure 8 With the axial direction of the motor structure 1 as the up and down direction, the through hole 33 is located at the bottom of the outlet channel. When sand or other debris from the outside of the motor structure 1 enters the outlet channel 60, it is convenient for the sand and other debris to flow out of the outlet channel 60 along the through hole 33, thereby effectively preventing sand or other debris from accumulating in the outlet channel 60 and entering the interior of the motor structure 1.

[0046] In some embodiments, the first extension portion 22 and the second extension portion 32 are spaced apart by a first predetermined distance (eg, Figure 8 In the embodiment of the present application, the first predetermined distance may be slightly larger than the diameter of the motor lead 50. In the embodiment of the present application, by limiting the distance between the first extension portion 22 and the second extension portion 32, while ensuring that the motor lead 50 is accommodated, it is possible to prevent debris or sand outside the motor structure 1 from entering the interior of the motor structure 1.

[0047] Please also refer to Figure 9In some embodiments, the first extension portion 22 includes a first connecting sub-portion 221 and a second connecting sub-portion 222, the first connecting sub-portion 221 is connected to the motor end cover 20, the first connecting sub-portion 221 is also connected to the second connecting sub-portion 222, and the first connecting sub-portion 221 and the second connecting sub-portion 222 are arranged obliquely or vertically in a bent shape; the second extension portion 32 includes a first extension sub-portion 321 and a second extension sub-portion 322, the first extension sub-portion 321 is connected to the main body 31, the first extension sub-portion 321 is also connected to the second extension sub-portion 322, and the first extension sub-portion 321 and the second extension sub-portion are arranged obliquely or vertically; wherein the second connecting sub-portion 222 is bent from the motor end cover 20 side toward the motor body 30 side, and the second extension sub-portion 322 is bent from the motor body 30 side toward the motor end cover 20 side, so that the first extension portion 22 and the second extension portion 32 are adapted to form a bent wire outlet channel 60.

[0048] As an embodiment, in the embodiment of the present application, one or more through holes 33 are provided in the first extension sub-section 321, that is, the through hole 33 structure in the second extension sub-section 32 can be provided in the first extension sub-section 321 connecting the second extension sub-section 322 and the main body 31, so that debris entering the outlet channel 60 can fall along the through hole 33, thereby avoiding the accumulation of debris.

[0049] Please also refer to Figure 10 、 Figure 11 and Figure 12 As an embodiment, the first extension portion 22 further includes a third connecting sub-portion 223, the third connecting sub-portion 223 is connected to the second connecting sub-portion 222, and the third connecting sub-portion 223 has the same extension direction as the first extension sub-portion 321, and extends to a second preset distance (such as 1 / 4) from the second extension sub-portion 322. Figure 11 h2); In the embodiment of the present application, three sections of bent connecting sub-sections are provided in the first extension portion 22 to match the second extension portion 32 to form multiple outlet cavity sections, thereby achieving a better blocking effect. As an embodiment, the diameter of the through hole 33 gradually decreases in the direction away from the outlet channel 60. In the embodiment of the present application, the aperture of the through hole 33 located in the first extension sub-section 321 can gradually increase from the motor end cover 20 side toward the motor body 30 side, making it easier for debris entering through the outlet channel 60 to leak out.
