Detailed Implementation

[0032] Many air conditioners currently require air swing, which necessitates the use of a motor. However, the motor is typically located near the air outlet. When the air conditioner is in cooling mode, the motor is easily condensed with water from the surrounding air, potentially causing short circuits and other damage. Therefore, current air conditioners generally insulate and waterproof the motor. The designers of this application discovered that existing technologies involve wrapping the motor in foam or insulation cotton, but this is ineffective because the motor's location at the air outlet means this method cannot guarantee a seal, allowing condensation to enter and affect the motor. Furthermore, this approach increases manufacturing steps, raw material requirements, and space requirements. Therefore, this application provides a motor that improves insulation and waterproofing, simplifies assembly, and reduces structural space, along with an air conditioner using this motor.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Please see Figure 1 and Figure 2 This invention provides a motor 10 for use in household appliances, such as air conditioners. The air conditioner can be a wall-mounted, floor-standing, ceiling-mounted, or portable unit. Optionally, the motor 10 can be connected to the air-sweeping blades of the air conditioner to drive the blades to swing, thereby achieving air sweeping. The type of motor 10 is not specifically limited; for example, it can be a stepper motor.

[0035] The motor 10 includes a housing 100 and a cover 200. The housing 100 includes an outer housing 110 and an inner housing 120. The inner housing 120 is disposed inside the outer housing 110 and forms a receiving cavity 121 inside the inner housing 120. The receiving cavity 121 is used to receive the internal components of the motor 10. At least one of the outer housing 110 and the inner housing 120 is connected to the cover 200. A first heat insulation layer 130 is disposed between the outer housing 110 and the inner housing 120.

[0036] It should be noted that the internal components of the motor 10 are components housed within the inner housing 120, such as the stator and rotor of the motor 10. The rotating shaft 300 of the motor 10 extends out of the housing 100 from the housing 121 to facilitate transmission connection with the component to be driven.

[0037] The motor 10 provided in this embodiment of the invention, due to its double-layer structure consisting of an outer shell 110 and an inner shell 120, and the provision of a first insulation layer 130 between the outer shell 110 and the inner shell 120, effectively insulates the motor 10 and improves its insulation performance. Furthermore, it effectively prevents condensation from the surrounding environment and the motor's own condensate from entering the motor 10 and damaging its internal components. Moreover, the motor 10 has its own built-in insulation structure, eliminating the need for an external insulation structure and additional insulation, thus improving assembly efficiency, saving assembly space, reducing the number of insulation components, saving costs, and enhancing product competitiveness.

[0038] Please continue reading. Figure 1 and Figure 2 The first embodiment of the present invention provides a motor 10, wherein an outer housing 110 and an inner housing 120 of the motor 10 are spaced apart to form a heat-insulating cavity 140, and a first heat-insulating layer 130 is disposed within the heat-insulating cavity 140. The first heat-insulating layer 130 may be a vacuum layer or a heat-insulating cotton layer. If the first heat-insulating layer 130 is a vacuum layer, it should be understood that the heat-insulating cavity 140 is evacuated to form a vacuum layer. Optionally, the heat-insulating cavity 140 can be evacuated using a tailless vacuum method, and the higher the vacuum level, the better the heat-insulating effect. If the first heat-insulating layer 130 is a heat-insulating cotton layer, heat-insulating cotton can be placed within the heat-insulating cavity 140 to form a heat-insulating cotton layer, which can also improve the heat-insulating effect. In this embodiment, the first heat-insulating layer 130 is a vacuum layer.

[0039] Furthermore, in this embodiment, an opening communicating with the accommodating cavity 121 is formed on one side of the inner shell 120, and a gap 122 is formed between one side of the outer shell 110 and the side of the inner shell 120 with the opening, the gap 122 communicating with the heat insulation cavity 140. Both the outer shell 110 and the inner shell 120 are connected to the cover 200, the cover 200 covering the opening and the gap 122, and the cover 200 and the inner shell 120 together form the accommodating cavity 121.

[0040] It should be noted that in this embodiment, the inner shell 120 and the outer shell 110 have similar shapes, both being cylindrical structures with an opening on one side and a bottom wall on the other. The inner shell 120 is smaller than the outer shell 110 and is disposed inside the outer shell 110. The same side of both the inner shell 120 and the outer shell 110 is closed by the cover 200. In this embodiment, the cover 200 is an upper cover, that is, the top side of the inner shell 120 and the outer shell 110 is covered by the cover 200, and the rotating shaft 300 of the motor 10 extends out from the cover 200.

[0041] In other modified embodiments, the cover 200 may also be a bottom cover, with the top sides of the inner housing 120 and the outer housing 110 covered by the cover 200 as a bottom cover, and the rotating shaft 300 of the motor 10 extending from one end of the inner housing 120 and the outer housing 110 relative to the cover 200.

[0042] The structure employs a design where both the inner housing 120 and the outer housing 110 are enclosed on the same side by a cover 200. After the internal components of the motor 10 are placed in their predetermined positions within the accommodating cavity 121 of the inner housing 120, the motor 10 can be assembled by covering it with the cover 200 and connecting the cover 200 to the top of both the outer housing 110 and the inner housing 120. This effectively improves assembly efficiency.

[0043] One end face of the outer shell 110 and the end face of the inner shell 120 with an opening are both bonded to the cover 200. In this way, when the cover 200 is attached to the top side of the outer shell 110 and the inner shell 120 respectively, waterproof adhesive can be used at the bonding point to ensure that the cover 200 is securely connected to the top side of the outer shell 110 and the inner shell 120 respectively, thereby improving assembly efficiency.

[0044] In addition, in this embodiment, the shaft 300 and gear of the motor 10 are made of non-metallic materials, which can eliminate cold bridges and prevent the motor 10 from being affected by condensation due to temperature difference, thus ensuring the service life of the motor 10.

[0045] To further improve the insulation effect, in this embodiment, a second insulation layer 210 is provided inside the cover 200. The second insulation layer 210 is either a vacuum layer or an insulation cotton layer. It should be understood that the second insulation layer 210 is similar to the first insulation layer 130; that is, the cover 200 also has a double-layer structure, with the second insulation layer 210 disposed within its internal cavity. If the second insulation layer 210 is a vacuum layer, it should be understood that the internal cavity of the cover 200 is evacuated to form a vacuum layer. If the second insulation layer 210 is an insulation cotton layer, insulation cotton can be placed inside the internal cavity of the cover 200 to form an insulation cotton layer, which also improves the insulation effect.

[0046] Because the cover 200 is provided with a second insulation layer 210, and combined with the first insulation layer 130 between the inner shell 120 and the outer shell 110, an insulation structure is formed around the entire inner shell 120, which can effectively improve the insulation effect of the motor 10.

[0047] Please see Figure 3 The motor 20 provided in the second embodiment of the present invention differs from that in the first embodiment in that the structures of the housing 100 and the cover 200 are different. For any aspects not mentioned herein, please refer to the first embodiment.

[0048] Please see Figures 3-5 In the second embodiment of the motor 20, the housing 100 may include an inner housing 120, an outer housing 110, and a connecting plate 150. The inner housing 120 is disposed within the outer housing 110, and a receiving cavity 121 is formed within the inner housing 120. The receiving cavity 121 is used to house the internal components of the motor 20. A heat-insulating cavity 140 is formed between the outer housing 110 and the inner housing 120. A first heat-insulating layer 130 is disposed within the heat-insulating cavity 140, which effectively insulates the motor 20 and improves the heat insulation effect. The first heat-insulating layer 130 can be a vacuum layer or a heat-insulating cotton layer; in the second embodiment, a vacuum layer is used. An opening communicating with the accommodating cavity 121 is formed on one side of the inner housing 120. One side of the outer housing 110 is connected to the side of the inner housing 120 with the opening via a connecting plate 150, so that the housing 100 forms a double-layer closed structure. The cover 200 is connected to at least one of the outer housing 110 and the inner housing 120 and the connecting plate 150, respectively, and covers the opening, so that the cover 200 and the inner housing 120 together form the accommodating cavity 121. The rotating shaft 300 of the motor 20 extends out from the cover 200, which serves as the upper cover.

[0049] It should be noted that in the second embodiment, the inner shell 120 and the outer shell 110 have similar shapes, both being cylindrical structures with an opening on one side and a bottom wall on the other. The difference from the first embodiment is that the inner shell 120 and the outer shell 110 are connected by a connecting plate 150, sealing the openings of both shells and forming a double-layered sealed structure. The cover 200 is simultaneously connected to the end face of the inner shell 120, the end face of the outer shell 110, and the connecting plate 150. This further prevents condensate from entering the motor 20 and damaging it.

[0050] In the second embodiment, the cover 200 adopts a snap-fit ​​structure. The cover 200 is an upper cover and may include a cover body 220 and a fastening portion 230 connected to the outer periphery of the cover body 220. The cover body 220 is connected to at least one of the outer shell 110 and the inner shell 120 and the connecting plate 150, respectively, and covers the opening. The fastening portion 230 covers at least a portion of the outer shell 110, so that the cover 200 is snapped onto the outer shell 110.

[0051] It should be understood that the entire cover 200 is inverted and placed over the upper part of the housing 100. The cover body 220 is generally disc-shaped, with a fastening part 230 protruding to one side surrounding its outer periphery. When the cover body 220 is connected to the connecting plate 150 and to at least one of the outer housing 110 and the inner housing 120, the fastening part 230 covers the upper part of the entire housing 100, that is, covers the upper part of the outer housing 110.

[0052] Optionally, the cover body 220 is bonded to at least one of the outer shell 110 and the inner shell 120, as well as the connecting plate 150, and / or the fastening part 230 is bonded to the upper outer side wall of the outer shell 110. It should be noted that at least one of the outer shell 110 and the inner shell 120, as well as the connecting plate 150, can be bonded with waterproof adhesive at the contact points with the cover body 220; alternatively, the fastening part 230 can be bonded with waterproof adhesive at the contact point with the upper outer side wall of the outer shell 110. Bonding at least one of the above two contact points ensures a secure connection between the cover body 200 and the shell 100. In the second embodiment, both contact points are bonded to further improve the stability of the connection.

[0053] After the internal components of the motor 20 are installed in the accommodating cavity 121, the cover 200 can be inverted onto the housing 100. Due to this installation structure where the cover 200 is inverted onto the housing 100, condensate can flow down from the cover 200 along the outer wall of the fastening part 230, thereby preventing condensate from seeping into the motor 20 from the cover 200 and causing damage to the motor 20. Furthermore, the fastening method makes installation more convenient.

[0054] In addition, in the second embodiment, a second insulation layer 210 is also provided inside the cover 200. Optionally, a second insulation layer 210 is provided inside both the cover body 220 and the fastening part 230. The second insulation layer 210 can be a vacuum layer or an insulation cotton layer. This further improves the insulation effect of the motor 20. In the second embodiment, the second insulation layer 210 is a vacuum layer. Furthermore, it should be understood that in other modified embodiments, the second insulation layer 210 can also be selectively provided in either the cover body 220 or the fastening part 230.

[0055] Please see Figure 6 and Figure 7 The third embodiment of the present invention provides another type of motor 30. The motor 30 provided in the third embodiment differs from that in the first and second embodiments in that the cover 200 in the third embodiment is a bottom cover and the accommodating cavity 121 is formed separately by the inner shell 120. In addition, for any matters not mentioned, please refer to the first and second embodiments.

[0056] In the third embodiment, the inner shell 120 is disposed within the outer shell 110, and a receiving cavity 121 is formed within the inner shell 120. The receiving cavity 121 is used to accommodate the internal components of the motor 30. The cover 200 is connected to the outer shell 110, and optionally, one end of the cover 200 is bonded to the outer shell 110. A first insulation layer 130 is provided between the outer shell 110 and the inner shell 120, and between the cover 200 and the inner shell 120. The first insulation layer 130 can be a vacuum layer and an insulation cotton layer. In the third embodiment, the first insulation layer 130 is an insulation cotton layer.

[0057] It should be noted that the outer casing 110 is a generally cylindrical structure with an open bottom. The outer casing 110 may include an outer peripheral sidewall 111 and a top sidewall 112 connected to one end of the outer peripheral sidewall 111. The top sidewall 112 is disposed opposite to the cover 200, and a first through hole 113 is provided on the top sidewall 112 for the shaft 300 of the power supply 30 to pass through. The end of the cover 200 away from the top sidewall 112 is connected to the outer peripheral sidewall 111 to close the bottom opening of the outer casing 110. Optionally, the end of the cover 200 away from the top sidewall 112 is bonded with waterproof adhesive, which can improve assembly efficiency.

[0058] The inner shell 120 includes an inner peripheral sidewall 123 and a first inner shell sidewall 124 and a second inner shell sidewall 125 respectively connected to both ends of the inner peripheral sidewall 123. The first inner shell sidewall 124 is located at the top of the inner shell 120, and the second inner shell sidewall 125 is located at the bottom of the inner shell 120. The inner peripheral sidewall 123, the first inner shell sidewall 124, and the second inner shell sidewall 125 together form a receiving cavity 121.

[0059] In the third embodiment, the insulation layer may include at least one of an upper insulation layer 131, an outer wall insulation layer 132, and a lower insulation layer 133. That is, one or more of the upper insulation layer 131, outer wall insulation layer 132, and lower insulation layer 133 can be arbitrarily chosen. In the third embodiment, to improve the insulation effect, all three layers—upper insulation layer 131, outer wall insulation layer 132, and lower insulation layer 133—are provided.

[0060] In the third embodiment, the upper insulation cotton 131 is disposed between the top sidewall 112 and the first inner shell sidewall 124 to insulate the top of the motor 30. The upper insulation cotton 131 has a second through hole 134 for the shaft 300 of the motor 30 to pass through. The outer wall insulation cotton 132 is disposed between the outer peripheral sidewall 111 and the inner peripheral sidewall 123 to insulate the circumferential portion of the motor 30. The lower insulation cotton 133 is disposed between the cover 200 and the second inner shell sidewall 125 to insulate the bottom of the motor 30. By disposing of the upper insulation cotton 131, the outer wall insulation cotton 132, and the lower insulation cotton 133, an insulation structure is formed surrounding the entire inner shell 120, effectively improving the insulation effect of the motor 30.

[0061] It should be noted that the upper insulation cotton 131, the outer wall insulation cotton 132, and the lower insulation cotton 133 are disposed between the inner shell 120 and the outer shell 110. They can be connected to their respective parts, or they can be placed between the two without being connected.

[0062] In the third embodiment, during assembly, the upper insulation cotton 131 and the outer wall insulation cotton 132 can be placed in the outer shell 110. Then, the inner shell 120, which already contains the internal components of the motor 30, is placed in the outer shell 110, so that the rotating shaft 300 of the motor 30 passes through the first inner shell side wall 124, the second through hole 134 and the first through hole 113 in sequence and extends out of the outer shell 110. Then, the lower insulation cotton 133 is placed, and the cover 200 is placed on the bottom of the motor 30. The cover 200 is then bonded to the end of the outer peripheral side wall 111 away from the top side wall 112 with waterproof adhesive.

[0063] In the third embodiment, since the cover 200 is a bottom cover, condensate can flow down from the top side wall 112 of the outer shell 110 along the outer peripheral side wall 111, thereby preventing condensate from seeping into the motor 30 and causing damage to the motor 30.

[0064] In summary, the motors 10, 20, and 30 provided in the embodiments of the present invention, due to their double-layer structure of the housing 100 consisting of an outer shell 110 and an inner shell 120, and the provision of a first insulation layer 130 between the outer shell 110 and the inner shell 120, effectively insulate the motors 10, 20, and 30, improving the insulation effect. Furthermore, they effectively prevent condensation from the surrounding environment and their own internal condensation from entering the motors 10, 20, and 30 and damaging their internal components, thus improving waterproofing. Moreover, the motors 10, 20, and 30 have built-in insulation structures, eliminating the need for external insulation and additional insulation, improving assembly efficiency, saving assembly space, reducing the number of insulation components, saving costs, and enhancing product competitiveness. Additionally, the rotating shaft 300 and gear parts of the motors 10, 20, and 30 are made of non-metallic materials, further reducing costs.

[0065] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
