Description

Technical Field

[0001] This invention belongs to the field of air conditioning technology, and more particularly to the field of energy-saving air conditioner technology, specifically relating to a motor bracket, an outdoor unit of an air conditioner, and an air conditioner. Background Technology

[0002] In existing air conditioner outdoor units, the motor bracket is usually only fixed to the condenser (i.e., heat exchanger) by a snap-fit ​​at the rear, which makes the motor prone to tilting and wobbling after installation. This tilting and wobbling reduces the gap between the fan blades and the guide ring, making it unstable and reducing airflow efficiency. This leads to increased energy consumption of the air conditioner and also causes vibration and noise problems in the outdoor unit. Summary of the Invention

[0003] Therefore, the present invention provides a motor bracket, an outdoor unit of an air conditioner, and an air conditioner, which can overcome the shortcomings of the related technology in which the motor bracket of the outdoor unit of the air conditioner is only positioned with the heat exchanger by the rear side, and is prone to tilting and swaying left and right during motor installation and operation, which makes the gap between the fan blade and the guide ring smaller and unstable, reduces the efficiency of the air duct, which leads to increased energy consumption of the air conditioner, and also causes vibration and noise problems of the outdoor unit.

[0004] To address the aforementioned problems, the present invention provides a motor bracket, comprising a bracket body. When the bracket body is in use, the bottom end of the bracket body has a lower fixing member that is fixed to the chassis of the outdoor unit. The top end of the bracket body has a first fixing arm extending along a first direction and a second fixing arm extending along a second direction. The free ends of the first fixing arm and the second fixing arm are both used to form a limiting connection with the heat exchanger of the outdoor unit. The first direction and the second direction are not parallel.

[0005] In some embodiments, the heat exchanger has a first heat exchange portion extending along the first direction and a second heat exchange portion extending along the second direction, the first fixing arm being limitedly connected to the second heat exchange portion, and the second fixing arm being limitedly connected to the first heat exchange portion; and / or, the first direction is the width direction of the outdoor unit, and the second direction is the thickness direction of the outdoor unit.

[0006] In some embodiments, the second fixed arm includes a horizontal connecting plate and a U-shaped connecting portion located at one end of the horizontal connecting plate away from the support body, and the top end of the first heat exchange portion is fitted into the recess of the U-shaped connecting portion.

[0007] In some embodiments, the top surface of the horizontal connecting plate is lower than the top surface of the support body and the U-shaped connecting portion.

[0008] In some embodiments, the horizontal connecting plate includes a first plate connected to the support body and a second plate having the U-shaped connecting portion, wherein the first plate and the second plate are detachably connected by a spacing adjustment structure.

[0009] In some embodiments, the spacing adjustment structure includes a plurality of positioning posts spaced apart along the first direction on the top surface of the first plate and a plurality of positioning holes spaced apart along the first direction on the second plate. The center spacing of each positioning post is equal to the center spacing of each positioning hole, and each positioning post can be fitted into each positioning hole in a one-to-one correspondence. The number of positioning holes is greater than the number of positioning posts.

[0010] In some embodiments, the positioning pins and positioning holes are formed in two parallel rows in the second direction.

[0011] In some embodiments, a first protrusion protruding from the top surface of the second plate body between the two rows of positioning holes is stamped out. The first protrusion includes a parallel segment parallel to each row of positioning holes and a connecting segment between two of the parallel segments.

[0012] In some embodiments, a second protrusion protruding from the top surface of the second plate is further stamped on the second plate body. The second protrusion extends along the second direction and is located between the first protrusion and the U-shaped connecting portion.

[0013] In some embodiments, the first and / or second protrusions are layered rib structures, and the diameter of each layer of rib structure gradually decreases along the protrusion direction.

[0014] In some embodiments, the top of the support body has a top plate extending along the first direction, the top plate and the first fixing arm are respectively located on opposite sides of the support body, the second fixing arm is formed on the top plate, and the top plate can be fixedly connected to the top cover of the outdoor unit.

[0015] In some embodiments, a motor mounting structure is stamped on the bracket body. Along the height of the bracket body from top to bottom, the motor mounting structure includes an upper mounting surface, a spacer groove, and a lower mounting surface. The upper mounting surface and the lower mounting surface each have mounting through holes for connecting the motor. The spacer groove is recessed towards the back side of the upper mounting surface.

[0016] In some embodiments, the lower mounting surface protrudes at a greater height than the upper mounting surface protrudes at a greater height along the second direction; or, the lower mounting surface protrudes at the same height as the upper mounting surface along the second direction, and a gasket is provided on the lower mounting surface.

[0017] In some embodiments, when the height of the lower mounting surface protruding along the second direction is greater than the height of the upper mounting surface protruding along the second direction, the difference in protrusion height between the lower mounting surface and the upper mounting surface is d, where 1mm ≤ d ≤ 3mm; or, when a gasket is provided on the lower mounting surface, the gasket is an elastic gasket.

[0018] The present invention also provides an outdoor unit for an air conditioner, including the motor bracket described above.

[0019] The present invention also provides an air conditioner, including the above-described outdoor unit of the air conditioner.

[0020] The motor bracket, air conditioner outdoor unit, and air conditioner provided by this invention have the following beneficial effects:

[0021] The bottom of the motor bracket is fixedly connected to the outdoor unit chassis via a lower fixing member, while the top of the motor bracket is simultaneously connected to different positions of the heat exchanger via a first fixing arm and a second fixing arm in different directions (i.e., the aforementioned first and second directions). This allows for reliable positioning of the motor bracket in the front-back and left-right directions of the heat exchanger, minimizing the tilting and swaying of the motor during operation after installation. This results in a more uniform and stable gap between the fan blades and the air guide ring on the outdoor unit panel, improving air duct efficiency and thus enhancing the heat exchange efficiency of the outdoor unit. This also reduces the energy consumption of the air conditioner, reduces vibration and noise during operation, and prevents damage caused by excessively small gaps on one side leading to contact between the fan blades and the air guide ring.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0038] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90° or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0039] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0040] See also Figures 1 to 11 As shown, according to an embodiment of the present invention, a motor bracket is provided, including a bracket body 1. When the bracket body 1 is in use, the bottom end of the bracket body 1 (i.e., Figure 1The lower end (as shown) has a lower fixing member 2 that is fixed to the outdoor unit chassis 200. That is, the bracket body 1 is detachably connected to the outdoor unit chassis 200 via the aforementioned lower fixing member 2, thereby fixing the bottom end of the motor bracket. The top end of the bracket body 1 has a first fixing arm 3 extending in a first direction and a second fixing arm 4 extending in a second direction. The free ends of the first fixing arm 3 and the second fixing arm 4 are used to form a limiting connection with the heat exchanger 100 of the outdoor unit. The first direction and the second direction are not parallel. See details. Figure 11 The first and second directions shown are schematic diagrams, and in a specific embodiment, the aforementioned first fixed arm 3 and second fixed arm 4 each extend along a horizontal plane.

[0041] In this technical solution, the bottom end of the motor bracket is fixedly connected to the outdoor unit chassis 200 via the lower fixing member 2, and the top end of the motor bracket is simultaneously connected to the heat exchanger 100 at different positions in different directions (i.e., the aforementioned first direction and second direction) via the first fixing arm 3 and the second fixing arm 4. This allows for reliable positioning of the motor bracket in the front-back and left-right directions of the heat exchanger 100, thereby minimizing the tilting and shaking of the motor during operation after installation. This results in a more uniform and stable gap between the fan blade 402 and the air guide ring of the outdoor unit panel, improving the efficiency of the air duct and thus enhancing the heat exchange efficiency of the outdoor unit of the air conditioner, reducing the energy consumption of the air conditioner, reducing vibration and noise during the operation of the outdoor unit, and preventing damage caused by the fan blade 402 contacting the air guide ring due to excessively small gaps on one side.

[0042] In some embodiments, the heat exchanger 100 has a first heat exchange portion 101 extending along the first direction and a second heat exchange portion 102 extending along the second direction. The first fixing arm 3 is limitedly connected to the second heat exchange portion 102, and the second fixing arm 4 is limitedly connected to the first heat exchange portion 101. See details below. Figure 11 As shown, in a specific embodiment, the aforementioned heat exchanger 100 is an L-shaped heat exchanger. In this case, the aforementioned first direction and second direction form an orthogonal perpendicular relationship, which can improve the support stability of the first fixed arm 3 and the second fixed arm 4 on the support body 1.

[0043] See details Figure 11 As shown, in this specific embodiment, the first direction is the width direction of the outdoor unit and the second direction is the thickness direction of the outdoor unit.

[0044] In some embodiments, the second fixed arm 4 includes a horizontal connecting plate 41 and a U-shaped connecting portion 42 located at the end of the horizontal connecting plate 41 away from the support body 1. The top end of the first heat exchange portion 101 is fitted into the recess of the U-shaped connecting portion 42. It should be noted that the surface of the aforementioned horizontal connecting plate 41 extends flatly along the horizontal plane, which can reduce its obstruction area with the heat exchange airflow of the heat exchanger 100, ensuring heat exchange efficiency while also reducing wind noise. The aforementioned recess is specifically formed by a first vertical plate, a second vertical plate, and a horizontal plate connected between the two vertical plates, arranged in parallel at intervals. When the aforementioned U-shaped connecting portion 42 is assembled with the heat exchanger 100, the aforementioned first vertical plate is located at the top edge of the outer wall of the heat exchanger 100, and the second vertical plate is located at the top edge of the inner wall of the heat exchanger 100, thereby achieving reliable fitting and limiting of the recess and the top end of the first heat exchange portion 101.

[0045] In this technical solution, the aforementioned notch and the top of the first heat exchange part 101 are used to achieve a matching and limiting connection, thereby realizing a reliable and stable limiting connection between the second fixed arm 4 and the heat exchanger 100.

[0046] In some embodiments, the top surface of the horizontal connecting plate 41 is lower than the top surface of the support body 1 and the U-shaped connecting portion 42.

[0047] In this technical solution, the top surface of the horizontal connecting plate 41 is lower than the top surface of the support body 1 and the U-shaped connecting part 42. On the one hand, this allows the second fixed arm 4 to objectively form a bent structure, thereby improving its support rigidity. Especially when the left and right width of the heat exchanger 100 is large, the extension length of the second fixed arm 4 is correspondingly large. At this time, the bent structure can ensure the reliability of the support limit of the second fixed arm 4. On the other hand, the horizontal connecting plate 41 objectively forms a structure that is low in the middle and high at both ends. In this way, when the heat exchanger 100 is used as a condenser, the condensate formed on the horizontal connecting plate 41 will be prevented from flowing to the support body 1 and then into the motor 401.

[0048] In some embodiments, the horizontal connecting plate 41 includes a first plate 411 connected to the support body 1 and a second plate 412 having the U-shaped connecting portion 42. The first plate 411 and the second plate 412 are detachably connected by a spacing adjustment structure (not indicated in the figure).

[0049] In this technical solution, the horizontal connecting plate 41 includes two relatively independent first plate 411 and second plate 412. The two plates are detachably connected by a spacing adjustment structure. On the one hand, this facilitates the assembly and connection of the horizontal connecting plate 41 between the bracket body 1 and the heat exchanger 100. On the other hand, the spacing adjustment structure can adjust the spacing between the first plate 411 and the second plate 412 while realizing the connection between them. This allows the length of the first fixed arm 3 to be adjusted according to actual needs. Thus, the motor bracket of this invention can be applied to heat exchangers 100 of different specifications (with different widths on the left and right) and air conditioner outdoor units.

[0050] The aforementioned spacing adjustment mechanism can be, for example, a connection structure formed by a telescopic component. However, this implementation is structurally complex and has high manufacturing costs. For a preferred implementation, please refer to [link to relevant documentation]. Figure 3 As shown, the spacing adjustment structure includes a plurality of positioning posts 4111 spaced apart along the first direction on the top surface of the first plate 411 and a plurality of positioning holes 4121 spaced apart along the first direction on the second plate 412. The center spacing of each positioning post 4111 is equal to the center spacing of each positioning hole 4121, and each positioning post 4111 can be fitted into each positioning hole 4121 in a one-to-one correspondence. The number of positioning holes 4121 is greater than the number of positioning posts 4111. The aforementioned positioning holes 4121 are through holes. It is understood that, in order to ensure the reliability of the insertion (or embedding) connection between each positioning post 4111 and the positioning hole 4121, the height of the aforementioned positioning post 4111 should be greater than the hole depth of the positioning hole 4121.

[0051] In this technical solution, multiple positioning posts 4111 and positioning holes 4121 are respectively set on the first plate 411 and the second plate 412 at intervals along the first direction. The connection between the two plates is achieved by the interlocking of the positioning posts 4111 and the positioning holes 4121 at different positions, and the distance between them is adjusted at the same time. The structure is simple and easy to operate.

[0052] In some embodiments, the positioning pins 4111 and positioning holes 4121 are respectively formed in two parallel rows in the second direction, see details. Figure 3 As shown, two rows of positioning posts 4111 are arranged parallel to each other along the second direction on the opposite sides of the first plate 411, and two rows of positioning holes 4121 are arranged parallel to each other along the second direction on the opposite sides of the second plate 412. This achieves a reliable connection between the positioning posts 4111 and the positioning holes 4121 on the width direction (i.e., the second direction) of the first plate 411 and the second plate 412, preventing structural torsion caused by excessive plate width.

[0053] In some embodiments, the diameter of each positioning post 4111 is N mm, and correspondingly, the diameter of the positioning hole is C = N + 0.2 mm, wherein N is preferably 3 mm, and the center distance between each positioning post 4111 is D = 2N + 0.5 mm, so as to ensure the stability and adaptability of the snap-fit ​​connection, and to ensure the adjustment accuracy and connection reliability.

[0054] The width of the aforementioned U-shaped connecting part 42 in the second direction is A, the thickness of the aforementioned first heat exchange part 101 in the second direction is X, A = X + 0.8 mm, the length of the aforementioned U-shaped connecting part 42 in the first direction is B, and the length of the aforementioned first heat exchange part 101 in the first direction is Y, B = Y + 3 mm.

[0055] In some implementation methods, see details. Figure 5 As shown, a first protrusion 4122 protruding from the top surface of the second plate 412 between the two rows of positioning holes 4121 is formed by stamping. The first protrusion 4122 includes parallel segments (not labeled in the figure) parallel to each row of positioning holes 4121 and connecting segments (not labeled in the figure) between two parallel segments. In a specific embodiment, the aforementioned connecting segments extend along the second direction, thereby making the first protrusion 4122 form an I-shaped structure, further improving the rigidity of the first protrusion 4122 to the second plate 412.

[0056] In this technical solution, on the one hand, stamping the first protrusion 4122 on the second plate 412 can significantly improve the structural strength of the second plate 412. On the other hand, the parallel segments formed at both ends of the first protrusion 4122 correspond to the positions of each positioning hole 4121, which can specifically improve the connection strength at that point, thereby ensuring the reliability of the connection between the first plate 411 and the second plate 412.

[0057] In some embodiments, a second protrusion 4123 protruding from the top surface of the second plate 412 is also formed by stamping on the second plate 412. The second protrusion 4123 extends along the second direction and is located between the first protrusion 4122 and the U-shaped connecting portion 42.

[0058] In this technical solution, the stamping of the second protrusion 4123 can further improve the mechanical strength of the second plate 412. At the same time, it can also form a condensate drainage groove between the second protrusion 4123 and the U-shaped connection 42, further preventing condensate from flowing along the second fixed arm 4 to the support body 1.

[0059] In some embodiments, the first protrusion 4122 and / or the second protrusion 4123 are layered rib structures, and the diameter of each layer of ribs gradually decreases along the protrusion direction, which can further improve the structural strength of the plate. See details below. Figure 6 As shown in the figure, a two-layer rib structure is illustrated. In a specific embodiment, the lower rib has a protrusion height of 3.5mm (between 2.5mm and 4mm) and the upper rib has a protrusion height of 2.5mm (between 2mm and 4mm). This is to prevent the protrusions from being too small to provide reinforcement, or too large to easily break the sheet metal due to its low ductility.

[0060] In some embodiments, the top of the bracket body 1 has a top plate 11 extending (horizontally arranged) along the first direction. The top plate 11 and the first fixing arm 3 are respectively located on opposite sides of the bracket body 1. The second fixing arm 4 is formed on the top plate 11, and the top plate 11 can be fixedly connected to the top cover of the outdoor unit (not shown in the figure, not indexed), which can further improve the structural stability of the motor bracket.

[0061] In some embodiments, a motor mounting structure 5 is stamped on the bracket body 1. Along the height of the bracket body 1 from top to bottom (with the orientation of the motor bracket in use as a reference), the motor mounting structure 5 includes an upper mounting surface 51, a spacer groove 52, and a lower mounting surface 53. The upper mounting surface 51 and the lower mounting surface 53 each have mounting through holes 54 for connecting the motor 401. The spacer groove 52 is recessed towards the back side of the upper mounting surface 51, which is the side of the upper mounting surface 51 that does not contact or engage with the motor 401.

[0062] In this technical solution, compared with the planar (vertical plane) motor mounting structure in the prior art, the motor mounting structure 5 in this application includes an upper mounting surface 51, a lower mounting surface 53 and a spacer groove 52 between the two. Since it is formed by stamping, it can improve the structural strength of the motor mounting structure 5 and improve the structural stability of the motor 401 after installation.

[0063] In some embodiments, the lower mounting surface 53 protrudes higher along the second direction than the upper mounting surface 51. It is understood that the protrusion directions of the lower mounting surface 53 and the upper mounting surface 51 are opposite to the extension direction of the first fixed arm 3, but the same as the extension direction of the top plate 11. In a specific embodiment, when the height of the lower mounting surface 53 protruding higher along the second direction is greater than the height of the upper mounting surface 51 protruding higher along the second direction, the difference in protrusion height between the lower mounting surface 53 and the upper mounting surface 51 is d, where 1mm ≤ d ≤ 3mm.

[0064] In this technical solution, the protrusion height of the lower mounting surface 53 is designed to be higher than that of the upper mounting surface 51. This utilizes the height difference between the two mounting surfaces to resist the torque caused by the weight of the motor 401 and the fan blade 402, thereby preventing the fan blade 402 from sagging, ensuring the uniformity of the gap between the fan blade 402 and the air guide ring, improving the efficiency of the air duct, enhancing the stability of the fan operation, reducing the vibration and noise of the outdoor unit, improving the heat exchange efficiency of the air conditioner, and improving the energy efficiency of the air conditioner.

[0065] In other embodiments, the lower mounting surface 53 protrudes at the same height as the upper mounting surface 51 along the second direction, and a gasket (not shown in the figure) is provided on the lower mounting surface 53. This allows the mounting surfaces of the motor 401 to objectively form the aforementioned height difference, effectively preventing the fan blade 402 from drooping during prolonged operation. The aforementioned gasket is preferably an elastic gasket, made of a suitable elastic material such as polyurethane or silicone.

[0066] It should be noted that, in a preferred embodiment, the aforementioned support body 1, top plate 11, lower fixing member 2, first fixing arm 3 and second fixing arm 4 are formed by bending and stamping high-strength metal materials such as Q235 stainless steel sheet metal parts to ensure structural rigidity and durability.

[0067] In order to minimize the obstruction of airflow by the support body 1, ventilation holes 12 are formed on the support body 1.
