Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and more specifically to a compressor and electrical equipment. Background Technology

[0002] In related technologies, compressors typically include a mechanical part and a motor part. The mechanical part includes cylinders, bearings, rollers, and crankshafts, while the motor part includes stator and rotor structures. The motor and mechanical parts are connected by a crankshaft. To ensure the stability of the rotor structure, a balancing component and a fan shroud are usually installed at the end of the rotor. Since the balancing component is usually fan-shaped, the fan shroud and the balancing component are matched on one side only, which makes the fan shroud susceptible to tilting due to airflow, thus affecting the efficiency of the compressor. Utility Model Content

[0003] The present invention aims to at least solve or improve the technical problem that the shroud on the balancing component of the compressor is prone to tilting in the prior art.

[0004] Therefore, the first aspect of this utility model proposes a compressor.

[0005] The second aspect of this utility model proposes an electrical device.

[0006] In view of the above, according to the first aspect of the present invention, the present invention provides a compressor, comprising: a rotor structure; a balancing component disposed at the end of the rotor structure, the balancing component having a mounting groove; and a fan shroud fixed on the balancing component, the fan shroud having a buckle that cooperates with the mounting groove.

[0007] The compressor proposed in this utility model includes a rotor structure, a balancing component, and a fan shroud. The balancing component is fixed on the rotor structure, and the fan shroud is fixed on the balancing component. The balancing component and the rotor structure rotate synchronously, thereby balancing the rotor structure. The fan shroud covers the balancing component, thereby reducing the disturbance to the airflow inside the compressor during the rotation of the balancing component.

[0008] The balance component has a mounting groove, and the fan cover has a buckle. The buckle and the mounting groove work together to limit the position of the fan cover. In other words, if the fan cover tilts, it needs to overcome the force of the mounting groove on the buckle, thereby reducing the possibility of the fan cover tilting, ensuring the stability of the compressor operation, and ensuring the efficiency of the compressor.

[0009] In addition, the compressor according to the above-described technical solution provided by this utility model may also have the following additional technical features:

[0010] In some embodiments, the compressor may optionally include a pressure plate disposed at one end of the fan shroud away from the rotor structure, the pressure plate being fixed to the balancing member.

[0011] In this embodiment, the compressor also includes a pressure plate disposed at the end of the fan shroud away from the rotor structure. The pressure plate and the balance component are fixedly connected. The fan shroud is clamped by the pressure plate and the balance component. The large contact area between the pressure plate and the fan shroud increases the fixing strength of the fan shroud and reduces the possibility of the fan shroud tilting.

[0012] In some embodiments, the pressure plate is optionally streamlined along the circumference of the shroud.

[0013] In this embodiment, the pressure plate is streamlined along the circumference of the shroud, thereby reducing the disturbance of the airflow inside the compressor by the pressure plate as it rotates with the rotor structure, thus ensuring the efficiency of the compressor.

[0014] In some embodiments, the compressor may optionally include at least one connector that passes through the pressure plate and the fan shroud and is connected to the balance member to secure the fan shroud and the pressure plate to the balance member.

[0015] In this embodiment, the compressor further includes at least one connector that passes through the pressure plate and the fan shroud. The connector is connected to the balancing component, thereby fixing the pressure plate and the fan shroud to the balancing component. Both the pressure plate and the fan shroud are fixed by the connector, which simplifies the installation steps of the compressor and reduces the installation difficulty of the compressor.

[0016] In some embodiments, optionally, the height of the pressure plate along the axial direction of the shroud is less than or equal to one-fifth of the height of the balancer.

[0017] In this embodiment, along the axial direction of the shroud, the height of the pressure plate is less than or equal to one-fifth of the height of the balance component, thereby reducing the volume of the pressure plate and reducing its impact on the airflow inside the compressor.

[0018] In some embodiments, optionally, the shroud protrudes from the pressure plate on both sides of the pressure plate along the radial direction of the shroud.

[0019] In this embodiment, along the radial direction of the shroud, the shroud protrudes from the pressure plate on both sides of the pressure plate, thereby reducing the volume of the pressure plate and reducing the influence of the pressure plate on the airflow inside the compressor.

[0020] In some embodiments, the thickness of the shroud may optionally range from 0.5 mm to 3 mm; the shroud may be formed by stamping steel; and the pressure plate may be made of manganese steel or silicon steel.

[0021] In this embodiment, the thickness of the shroud ranges from 0.5mm to 3mm, thereby ensuring the strength of the shroud while reducing its weight. The shroud is formed by stamping steel, making the entire shroud a one-piece structure, reducing the manufacturing difficulty and production cost of the shroud. The pressure plate is made of manganese steel or silicon steel, thereby ensuring the strength of the pressure plate. Furthermore, the pressure plate can be made from scrap laminations of rotor or stator structures, reducing the production cost of the pressure plate.

[0022] In some embodiments, optionally, one end of the balancing member is connected to the rotor structure, and the inner side of the other end of the balancing member has a mounting groove, into which a snap-fit ​​is inserted.

[0023] In this embodiment, one end of the balancing component is connected to the rotor structure, and the inner side of the other end of the balancing component has a mounting groove, so that the wind shield clamps the balancing component on the inner and outer sides, further improving the stability of the wind shield and reducing the possibility of the wind shield tilting.

[0024] In some embodiments, the shroud may optionally include: a first sidewall, the first sidewall being annular; and a second sidewall, located at one end of the first sidewall, the second sidewall being annular, with a snap fastener disposed on the inner side of the second sidewall.

[0025] In this embodiment, the wind shroud also includes a first sidewall and a second sidewall. The first sidewall is annular and is disposed around the circumference of the balancer. The second sidewall is located at the end of the first sidewall away from the rotor structure. The second sidewall is annular and has a buckle on its inner side. That is, the buckle and the first sidewall clamp the balancer on both sides of the balancer, thereby making the wind shroud clamp the balancer, further improving the stability of the wind shroud and reducing the possibility of the wind shroud tilting.

[0026] In some embodiments, the buckle is optionally annular, and the mounting groove and part of the buckle cooperate.

[0027] In this embodiment, the buckle is ring-shaped, and the mounting groove and part of the buckle cooperate, so that the balancing component can cooperate with multiple positions of the wind cover, thereby reducing the installation difficulty of the wind cover and the balancing component and improving production efficiency.

[0028] According to a second aspect of the present invention, an electrical device is provided, comprising: the compressor described in the first aspect embodiment.

[0029] The electrical device proposed in this utility model includes the compressor as described in the first aspect embodiment, and therefore has all the beneficial effects of the compressor as described in the first aspect embodiment, which will not be described in detail here.

It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0040] The following reference Figures 1 to 4 This invention describes a compressor 100 and an electrical device provided according to some embodiments of the present invention.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, according to a first aspect of the present invention, the present invention provides a compressor 100, the compressor 100 including a rotor structure 110, a balancing component 120 and a fan shroud 130, the balancing component 120 being fixed on the rotor structure 110 and located at the end of the rotor structure 110, the fan shroud 130 being disposed on the balancing component 120, wherein the balancing component 120 has a mounting groove 122 and the fan shroud 130 has a buckle 132, the buckle 132 and the mounting groove 122 cooperating with each other.

[0042] The compressor 100 provided by this utility model includes a rotor structure 110, a balancing component 120, and a fan shroud 130. The balancing component 120 is fixed on the rotor structure 110, and the fan shroud 130 is fixed on the balancing component 120. The balancing component 120 and the rotor structure 110 rotate synchronously, thereby balancing the rotor structure 110. The fan shroud 130 covers the balancing component 120, thereby reducing the disturbance to the airflow inside the compressor 100 during the rotation of the balancing component 120.

[0043] The balance component 120 has a mounting groove 122, and the fan cover 130 has a buckle 132. The buckle 132 and the mounting groove 122 cooperate to limit the position of the fan cover 130. That is, if the fan cover 130 tilts, it needs to overcome the force of the mounting groove 122 on the buckle 132, thereby reducing the possibility of the fan cover 130 tilting, ensuring the stability of the compressor 100 operation, and ensuring the efficiency of the compressor 100.

[0044] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the compressor 100 may optionally include a pressure plate 140, which is disposed on the fan shroud 130.

[0045] In this embodiment, the compressor 100 also includes a pressure plate 140 disposed at one end of the fan shroud 130 away from the rotor structure 110. The pressure plate 140 and the balance member 120 are fixedly connected. The fan shroud 130 is clamped by the pressure plate 140 and the balance member 120. The large contact area between the pressure plate 140 and the fan shroud 130 increases the fixing strength of the fan shroud 130 and reduces the possibility of the fan shroud 130 tilting.

[0046] Specifically, the number of pressure plates 140 can be one, two, or more.

[0047] like Figure 1 and Figure 4 As shown, in some embodiments, optionally, the pressure plate 140 is streamlined along the circumference of the shroud 130.

[0048] In this embodiment, the pressure plate 140 is streamlined along the circumference of the shroud 130, thereby reducing the disturbance of the airflow inside the compressor 100 by the pressure plate 140 as it rotates with the rotor structure 110, thus ensuring the efficiency of the compressor 100.

[0049] Specifically, the pressure plate 140 may be fan-shaped, or the end of the pressure plate 140 may have a guide portion, or the pressure plate 140 may be generally curved spindle-shaped, or the pressure plate 140 may be generally curved wedge-shaped, etc. The guide portion may have a pointed tip or a curved end, thereby reducing the influence of the pressure plate 140 on the airflow inside the compressor 100 when it rotates.

[0050] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the compressor 100 may optionally include at least one connector 150 for fixing the pressure plate 140 and the fan shroud 130. The connector 150 passes through the pressure plate 140 and the fan shroud 130 and is connected to the balance member 120 to fix the fan shroud 130 and the pressure plate 140 to the balance member 120.

[0051] In this embodiment, the compressor 100 further includes at least one connector 150, which passes through the pressure plate 140 and the fan shroud 130, and is connected to the balance member 120, thereby fixing the pressure plate 140 and the fan shroud 130 on the balance member 120. Both the pressure plate 140 and the fan shroud 130 are fixed by the connector 150, which simplifies the installation steps of the compressor 100 and reduces the installation difficulty of the compressor 100.

[0052] Specifically, the connector 150 can be a screw or rivet, etc., and the number of connectors 150 can be one, two or more.

[0054] In this embodiment, along the axial direction of the shroud 130, the height H1 of the pressure plate 140 is less than or equal to one-fifth of the height H2 of the balance member 120, thereby reducing the volume of the pressure plate 140 and reducing the influence of the pressure plate 140 on the airflow inside the compressor 100.

[0055] Specifically, the height H1 of the pressure plate 140 can be equal to one-fifth, one-sixth, one-seventh, one-eighth, one-ninth, one-tenth, one-fifteenth, or one-twentieth of the height H2 of the balancer 120.

[0056] like Figure 4 As shown, in some embodiments, optionally, along the radial direction of the shroud 130, the length of the shroud 130 is greater than the length of the pressure plate 140, and protrudes from both sides of the pressure plate 140, that is, the orthogonal projection of the pressure plate 140 on the shroud 130 falls completely on the shroud 130.

[0057] In this embodiment, along the radial direction of the shroud 130, the shroud 130 protrudes from the pressure plate 140 on both sides of the pressure plate 140, thereby reducing the volume of the pressure plate 140 and reducing the influence of the pressure plate 140 on the airflow inside the compressor 100.

[0058] Specifically, such as Figure 2 and Figure 4 As shown, along the radial direction of the wind shroud 130, the outer side of the wind shroud 130 protrudes from the pressure plate 140, and the inner side of the wind shroud 130 protrudes from the pressure plate 140.

[0060] In this embodiment, the thickness of the wind shield 130 ranges from 0.5 mm to 3 mm, thereby ensuring the strength of the wind shield 130 while reducing its weight.

[0061] Specifically, the thickness D of the shroud 130 is 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm or 3mm, etc.

[0062] In some embodiments, the fan cover 130 may be a stamped part, the fan cover 130 may be a steel part, and the fan cover 130 may be formed by stamping steel.

[0063] In this embodiment, the wind shield 130 is formed by stamping steel, making the entire wind shield 130 a one-piece structure, reducing the manufacturing difficulty of the wind shield 130 and reducing the production cost of the wind shield 130.

[0064] In some embodiments, the pressure plate 140 may be made of manganese steel or silicon steel.

[0065] In this embodiment, the pressure plate 140 is made of manganese steel or silicon steel to ensure the strength of the pressure plate 140. Furthermore, the pressure plate 140 can be made from scrap laminations of the rotor structure 110 or stator structure to reduce the production cost of the pressure plate 140.

[0066] like Figure 2 and Figure 3 As shown, in some embodiments, optionally, at least a portion of the balance member 120 is fan-shaped, one end of the balance member 120 is connected to the rotor structure 110, and the inner side of the other end of the balance member 120 has a mounting groove 122, into which the buckle 132 is embedded.

[0067] In this embodiment, at least a portion of the balance member 120 is fan-shaped to match the shape of the rotor structure 110, ensuring the smooth rotation of the rotor structure 110. One end of the balance member 120 is connected to the rotor structure 110, and the inner side of the other end of the balance member 120 has a mounting groove 122, so that the wind shield 130 clamps the balance member 120 on the inner and outer sides of the balance member 120, further improving the stability of the wind shield 130 and reducing the possibility of the wind shield 130 tilting.

[0068] Specifically, the balancer 120 and the rotor structure 110 can be connected by screws or rivets.

[0069] like Figure 2 and Figure 3 As shown, in some embodiments, optionally, the balancing component 120 includes: a mounting portion 124 connected to the rotor structure 110; a balancing portion 126 disposed on the side of the mounting portion 124 away from the rotor structure 110; a mounting groove 122 disposed on the balancing portion 126; and a wind shield 130 covering the balancing portion 126.

[0070] Specifically, the mounting part 124 is annular, and the balancing part 126 is fan-shaped. Along the radial direction of the wind cover 130, the outer side of the mounting part 124 protrudes from the balancing part 126. The wind cover 130 covers the balancing part 126. Along the radial direction of the wind cover 130, the outer side of the mounting part 124 protrudes from the wind cover 130, or the outer side of the mounting part 124 is flush with the wind cover 130.

[0071] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the shroud 130 further includes: a first sidewall 134, which is annular; a second sidewall 136, located at one end of the first sidewall 134, which is annular, and a buckle 132 is disposed on the inner side of the second sidewall 136.

[0072] In this embodiment, the wind shield 130 further includes a first sidewall 134 and a second sidewall 136.

The second sidewall 136 is located at the end of the first sidewall 134 away from the rotor structure 110. The second sidewall 136 is annular and a buckle 132 is provided on the inner side of the second sidewall 136. That is, the buckle 132 and the first sidewall 134 respectively clamp the balance member 120 on both sides of the balance member 120, thereby making the wind shield 130 clamp the balance member 120, further improving the stability of the wind shield 130 and reducing the possibility of the wind shield 130 tilting.

[0073] Specifically, the buckle 132, the first sidewall 134, and the second sidewall 136 are all annular, with the first sidewall 134 located on the outer ring of the second sidewall 136 and the buckle located on the inner ring of the second sidewall 136.
