Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and particularly relates to a fixing component, a shaded-pole motor component and a warm air heater. Background Art

[0002] There are many types of motors. In recent years, in order to reduce product costs, shaded-pole motors are mostly used on warm air heaters to replace asynchronous motors. However, due to the special structure of shaded-pole motors, there is a tolerance of at least 0.7 mm in the thickness dimension of the stator in its own axial direction. Therefore, it is difficult to limit the shaded-pole motor through the stator in this direction. When the thickness of the stator changes but is still within the allowable range, limiting the shaded-pole motor by limiting the stator will result in a reduction in the installation position accuracy of the shaded-pole motor, which may cause collision interference between the internal fan blades of the warm air heater and the inner wall of the air duct, and further cause problems such as abnormal vibration and noise.

[0003] How to improve the accuracy of the fixed position of the shaded-pole motor is a technical problem that needs to be solved urgently at present. Summary of the Utility Model

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way restrictive of the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, up, down, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description. Without contrary explanations, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be understood as limiting the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0049] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. can be used here to describe the spatial positional relationship between a device or feature shown in a figure and other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure is inverted, a device described as "above or over other devices or structures" will then be positioned "below or under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0050] In addition, it should be noted that the use of terms such as "first" and "second" to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.

[0051] Referring to Figure 1-15 As shown, the present utility model provides a fixing assembly for limiting and fixing a shaded-pole motor 5 on a base 501. The axial direction of the shaded-pole motor 5 is the left-right direction, and it includes:

[0052] A connecting member 1 fixedly arranged on the shaded-pole motor 5. The connecting member 1 includes a positioning portion, and the positioning portion includes a first left side face facing the left and a first right side face facing the right.

[0053] A fixing member 2, which includes a second bottom plate 203, a second left side plate 201, and a second right side plate 202. The second left side plate 201 is arranged at the left end of the second bottom plate 203, and the second right side plate 202 is arranged at the right end of the second bottom plate 203. When the positioning portion is fixed on the second bottom plate 203, the first left side face abuts against the second left side plate 201, and the first right side face abuts against the second right side plate 202.

[0054] In this application, "left" and "right" are relative orientations along the axial direction of the shaded-pole motor 5. Among the two ends of the axis, when one end faces left, the other end faces right.

[0055] The prior art limits the stator of the shaded-pole motor, such as Figure 16-18As shown, since the stator is composed of a plurality of stacked sheets, it is easy for the stator thickness to change and thus fail to effectively limit the position. At this time, the stator is only fixed together with the fixing member by a positioning portion (generally, a through hole is provided on the positioning portion, and a threaded hole is provided on the second bottom plate, and the screw is passed through the through hole and then threadedly connected in the threaded hole). Due to the lack of necessary limiting, the shaded-pole motor is prone to skew. The skewness of the shaded-pole motor will further cause the fan blades driven by the shaded-pole motor to collide with the inner wall of the air duct, generating unnecessary vibration and noise.

[0056] The present application arranges a connector 1 on the shaded-pole motor 5 and a fixing member 2 on the base 501. When the connector 1 is fixed to the second bottom plate 203 through the positioning portion, the two side surfaces of the positioning portion are in contact with the two side plates of the fixing member 2, thereby limiting the left and right directions of the shaded-pole motor 5, thereby achieving the purpose of limiting the shaded-pole motor 5, improving the accuracy of the shaded-pole motor 5 on the base 501, and improving the consistency of the shaded-pole motor 5 during assembly, which is beneficial to improving the qualified rate of products and reducing the defective rate of products involving the shaded-pole motor 5; after the shaded-pole motor 5 is limited and fixed by the fixing assembly, it is beneficial to the smooth operation of the shaded-pole motor 5, thereby avoiding abnormal noise and vibration during the operation of the shaded-pole motor 5.

[0057] Preferably, Figure 10-11 As shown, the positioning portion includes a first bottom plate 103, a first left side plate 101 is disposed at the left end of the first bottom plate 103, and a first right side plate 102 is disposed at the right end of the first bottom plate 103; the first left side surface is the left side surface of the first left side plate 101, and the first right side surface is the right side surface of the first right side plate 102;

[0058] The first bottom plate 103 and the second bottom plate 203 are fixed together.

[0059] Through the above-mentioned arrangement, the first bottom plate 103 and the second bottom plate 203 of the present application have a limiting effect on the connection member 1 and the fixing member 2; and because the two side plates of the connection member 1 (specifically, the first left side and the first right side) are in contact with the two side plates of the fixing member 2 (specifically, the side of the second left side plate facing the right is the second left side, and the side of the second right side plate facing the left is the second right side, the first left side is in contact with the second left side, and the first right side is in contact with the second right side), the limiting accuracy between the connection member 1 and the fixing member 2 is improved.

[0060] Further, the first bottom plate 103 is parallel to the second bottom plate 203; the parallelism between the first bottom plate 103 and the second bottom plate 203 enables the first bottom plate 103 and the second bottom plate 203 to fit together to the greatest extent. Further, threaded holes can be provided on the second bottom plate 203, and through holes can be provided on the first bottom plate 103. After a bolt or screw 504 passes through the through hole on the first bottom plate 103, it is threadedly connected into the threaded hole, thereby pressing the connecting member 1 onto the fixing member 2. The screw 504 or bolt tightens the first bottom plate 103 and the second bottom plate 203 together to realize the limiting and fixing of the shaded-pole motor 5 in the axial direction of the screw 504.

[0061] Preferably, as Figure 1-6 , shown in FIGS. 10-11, the first left side plate 101, the first right side plate 102 and the first bottom plate 103 enclose a first U-shaped block with an opening facing away from the base 501;

[0062] The second left side plate 201, the second right side plate 202 and the second bottom plate 203 enclose a second U-shaped block with an opening facing away from the base 501;

[0063] The first left side plate 101 and the first right side plate 102 are located between the second left side plate 201 and the second right side plate 202.

[0064] When installing and fixing the shaded-pole motor 5, first fix the connecting member 1 on the shaded-pole motor 5 and the fixing member 2 on the base 501. Since the opening faces away from the base 501, when moving the shaded-pole motor 5 to the base 501, the first U-shaped block can just be inserted into the second U-shaped block, thus improving the installation efficiency of the shaded-pole motor 5.

[0065] The connecting member 1 and the fixing member 2 are preferably made of a metal material.

[0066] Preferably, the first left side plate 101 is parallel to the second left side plate 201, the second right side plate 202 is parallel to the second right side plate 202, and the first bottom plate 103 is parallel to the second bottom plate 203.

[0067] Through the above settings, when the connecting member 1 and the fixing member 2 are fixed together, the first left side plate 101 and the second left side plate 201 are in surface contact, the first right side plate 102 and the second right side plate 202 are in surface contact, and the first bottom plate 103 and the second bottom plate 203 are in surface contact, improving the positioning accuracy and stability between the connecting member 1 and the fixing member 2, and further improving the installation accuracy and stability of the shaded-pole motor 5 on the base 501.

[0068] Preferably, as Figure 4, as shown in FIGS. 6, 13, and 15, the fixing component further includes a left limiting member 301 and a right limiting member 302. The base 501 includes a placement position 502 for placing the shaded-pole motor 5. The left limiting member 301 and the right limiting member 302 are respectively arranged on the left and right sides of the placement position 502;

[0069] The left side surface of the shaded-pole motor 5 includes a left limiting portion 401, and the right side surface of the shaded-pole motor 5 includes a right limiting portion 402. The distances from the left limiting portion 401 and the right limiting portion 402 to the placement position 502 are both smaller than the distance between the connecting member 1 and the placement position 502;

[0070] The left limiting member 301 is adjacent to the left limiting portion 401, and the right limiting member 302 is adjacent to the right limiting portion 402.

[0071] The shaded-pole motor 5 includes a pressing surface 503 for cooperating with the placement position 502. When the shaded-pole motor 5 is installed on the base 501, the pressing surface 503 faces the placement position 502, and there is a gap between the pressing surface 503 and the placement position 502, avoiding the situation that the connecting member 1 and the fixing member 2 cannot be effectively locked; further, a damping rubber pad is provided between the pressing surface 503 and the placement position 502, which can not only improve the support for the shaded-pole motor 5 but also absorb the inevitable vibration during the operation of the shaded-pole motor 5.

[0072] Since the distances from the left limiting portion 401 and the right limiting portion 402 to the pressing surface 503 are both smaller than the distance between the connecting member and the placement position 502, the limiting positions of the left limiting member 301 and the right limiting member 302 on the shaded-pole motor 5 are closer to the placement position 502 compared to the fixed limiting position between the connecting member 1 and the fixing member 2. This forms a three-dimensional limit for the shaded-pole motor 5, avoiding the left-right displacement of the end where the pressing surface 503 of the shaded-pole motor 5 is located due to lack of limit and being subjected to vibration. The accuracy of the limit for the shaded-pole motor 5 is improved.

[0073] Preferably, the left limiting member 301 includes a left elastic portion, and the right limiting member 302 includes a right elastic portion; when the shaded-pole motor 5 is not installed on the base 501, the distance between the left elastic portion and the right elastic portion is less than or equal to the minimum distance between the left limiting portion 401 and the right limiting portion 402.

[0074] Further, the distance between the left elastic portion and the right elastic portion is equal to the minimum distance between the left limiting portion 401 and the right limiting portion 402.

[0075] Since the distance between the left elastic part and the right elastic part is less than or equal to the minimum distance between the left limiting part 401 and the right limiting part 402; this makes it such that when the shaded-pole motor 5 is installed on the base 501, regardless of whether the distance between the left limiting part 401 and the right limiting part 402 is the minimum value or greater than the minimum value (as long as the dimensions between the left limiting part 401 and the right limiting part 402 are within a reasonable range, that is, within the operating error range, they can be limited by the left elastic part and the right elastic part), the left elastic part and the right elastic part will necessarily come into contact with the shaded-pole motor 5. That is to say, the left limiting member 301 and the right limiting member 302 will necessarily have a limiting effect on the shaded-pole motor 5. In the prior art, the left limiting body 601 (having the same position as the left limiting member 301 of the present application, with different structures and / or materials) and the right limiting body 602 (having the same position as the right limiting member 302 of the present application, with different structures / or materials) are rigid structures. To avoid the shaded-pole motor 5 being unable to be arranged between the left limiting body 601 and the right limiting body 602, the distance between the left limiting body 601 and the right limiting body 602 uses the upper limit tolerance. That is to say, it is set according to the maximum distance between the left limiting part 401 and the right limiting part 402 (the maximum distance within the error range, for example, allowing an error of 0.7 mm, and the maximum distance between the left limiting part 401 and the right limiting part 402 is the minimum distance plus 0.7 mm). This makes it such that when the distance between the left limiting part 401 and the right limiting part 402 is less than the maximum distance, the left limiting body 601 and the right limiting body 602 cannot abut against the left limiting part 401 and the right limiting part 402 to form an effective limit, and thus cannot effectively position the shaded-pole motor 5, resulting in the shaded-pole motor 5 being skewed. When the shaded-pole motor 5 is applied to the warm air heater 7, the distance between the cross-flow fan blade used in the warm air heater 7 and the inner wall surface of the air duct (volute) is relatively small, generally only about 3 mm. The skewing of the shaded-pole motor 5 that drives the cross-flow fan blade will cause the cross-flow fan blade to collide with the inner wall surface of the air duct, thereby causing the rotational speed of the cross-flow fan blade to decrease, generating abnormal vibration and noise, and ultimately affecting the user experience.

[0076] In the present application, the shaded-pole motor 5 is limited by the limiting method between the fixing member 2 and the connecting member 1. There will inevitably be errors in the connection limit between the fixing member 2 and the connecting member 1. The left limiting member 301 and the right limiting member 302 are used to assist in limiting and correcting the shaded-pole motor 5, improving the installation accuracy and operating stability of the shaded-pole motor 5.

[0077] Preferably, as Figure 4 shown, the left elastic part includes a first left section 3011 fixed on the base 501 and extending away from the base 501, a second left section 3012 extending rightward from the end of the first left section 3011 away from the base 501, and a third left section 3013 extending toward the base 501 from the right end of the second left section 3012;

[0078] The right elastic part includes a first right section 3021 fixed on the base 501 and extending away from the base 501, a second right section 3022 extending leftward from the end of the first right section 3021 away from the base 501, and a third right section 3023 extending toward the base 501 from the left end of the second right section 3022.

[0079] Through the above settings, both the left elastic part and the right elastic part form a U-shaped structure with an opening facing the base 501;

[0080] With the arrangement of the elastic parts of the two U-shaped structures, when the distance between the left limiting part 401 and the right limiting part 402 of the shaded-pole motor 5 is greater than the distance between the two elastic parts, it can prevent the shaded-pole motor 5 from being stuck by the elastic parts during installation, so that the first bottom plate 103 and the second bottom plate 203 cannot be effectively attached; since there is a certain gap between both the third left section 3013 and the third right section 3023 and the placement position 502, the left and right ends of the pressing surface 503 (the surface that fits with the placement position 502) of the shaded-pole motor 5 can be prevented from contacting the left limiting member 301 and the right limiting member 302 (the contact part between the limiting member and the base 501 generally has a transition fillet to improve the connection strength and reduce the concentrated stress), enabling the first bottom plate 103 and the second bottom plate 203 to be in full contact and improving the fixing stability of the shaded-pole motor 5.

[0081] In a second aspect, as shown in Figure 9 , 10, 12, 15, the present invention also provides a shaded-pole motor assembly, including the shaded-pole motor 5 and the fixing assembly. The shaded-pole motor 5 includes a clamping block 505, and the first left side plate 101 and the first right side plate 102 are fixed on the left and right sides of the clamping block 505.

[0082] By providing the clamping block 505, the clamping block 505 can be specially processed to improve the dimensional accuracy of the clamping block 505 itself, and further improve the accuracy of the distance between the first left side plate 101 and the first right side plate 102; the connection accuracy between the connecting member 1 and the fixing member 2 is also improved, which is beneficial to improving the installation accuracy of the shaded-pole motor 5.

[0083] Preferably, as shown in Figure 8 , a plurality of punching sheets are stacked from the left side to the right side of the shaded-pole motor 5 to form the stator 506 of the shaded-pole motor 5;

[0084] When the left limiting member 301 and the right limiting member 302 are provided, the left end face of the stator 506 is the left limiting part 401, and the right end face of the stator 506 is the right limiting part 402.

[0085] Make full use of the characteristics of the stator 506 of the shaded-pole motor 5. Without additional processing, the left limit member 301 and the right limit member 302 are respectively abutted against the two end faces (the left limit portion 401 and the right limit portion 402) of the stator 506 to further limit the position of the shaded-pole motor 5 and ensure the accuracy of the installation of the shaded-pole motor 5. Since the stator 506 is formed by stacking a plurality of iron sheets, there is an error in the thickness after stacking, and the error size generally does not exceed 0.7 mm. To prevent the left limit member 301 and the right limit member 302 from being unable to effectively limit the two ends of the stator 506, the left limit member 301 includes a left elastic portion, and the right limit member 302 includes a right elastic portion; when the shaded-pole motor 5 is not installed on the base 501, the distance between the left elastic portion and the right elastic portion is less than or equal to the minimum distance between the left limit portion 401 and the right limit portion 402. Regardless of the thickness of the stator 506 in the left-right direction, the left elastic portion and the right elastic portion can always be abutted against the left and right end faces of the stator 506 to further correct the stator 506.

[0086] In a third aspect, as Figure 12-15 shown, the present utility model provides a warm air heater, including the shaded-pole motor assembly described above for installing the shaded-pole motor 5 on the base 501;
