Furthermore, a guide surface is provided on the side of the reinforcing part away from the stator core.

During compressor operation, the area below the rotor core is a mixture of lubricating oil and refrigerant in an oil-gas environment. A larger pressure differential facilitates the upward flow of oil and gas (refrigerant and lubricating oil), increasing the flow rate and benefiting the compressor's cooling and lubrication. Specifically, if h1 is too small, the pressure differential is small, which is not conducive to the flow of the oil-gas mixture. If h1 is too large, the motor will be closer to the lower compression components (cylinder, blades, etc.), and the second frame will block the flow of the oil-gas mixture, which is also not conducive to lubrication. In this embodiment, the range of h1 is designed to be 13.9mm≤h1≤16mm, which avoids the above situations and improves the cooling and lubrication effect inside the compressor. The compressor stator insulation frame assembly with the above-described structure solves the technical problem in related technologies where poor internal refrigerant and lubricating oil flow affects the compressor's operating efficiency.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Please refer to Figures 1 to 6To address the technical problems described in the background section, this utility model provides a compressor stator insulation frame assembly. The compressor stator insulation frame assembly includes a first frame 1 and a second frame 2, which are used to correspond one-to-one with the two ends of the stator core 10 along the axial direction. The outer peripheral surface of the first frame 1 is provided with a reinforcing portion 11, which protrudes from the outer peripheral surface of the first frame 1 and has a guiding surface 111 for guiding the refrigerant and lubricating oil. When the first frame 1 is installed on the upper end of the stator core 10, the reinforcing portion 11 and the stator core 10... The core 10 is in contact, and the guide surface 111 is located on the side of the reinforcing part 11 away from the stator core 10; the second frame 2 includes an annular body part 101 and multiple winding teeth 102. The multiple winding teeth 102 are all disposed on the inner wall of the body part 101. The multiple winding teeth 102 are arranged sequentially and spaced apart along the circumference of the body part 101. A winding groove 103 is formed between any two adjacent winding teeth 102; wherein, the distance h1 between the end face of the body part 101 and the winding teeth 102 satisfies 13.9mm≤h1≤16mm, and the end face of the body part 101 is the end face of the body part 101 away from the stator core 10.

[0021] The compressor stator insulation frame assembly with this structural design has a reinforcing part 11 on the outer peripheral surface of the first frame 1. In use, the first frame 1 is assembled on the upper end of the stator core 10. After the first frame 1 and the stator core 10 are engaged, the reinforcing part 11 contacts the stator core 10, thereby providing reliable support and reinforcement for the relative position between the two. On this basis, a guide surface 111 is provided on the side of the reinforcing part 11 away from the stator core 10. The guide surface 111 can guide the refrigerant and lubricating oil (hereinafter referred to as oil vapor) inside the compressor, which helps to collect and fall the oil vapor above the motor, reduce the amount of oil discharged, reduce the amount of oil mist discharged with the refrigerant, improve the retention of refrigeration oil inside the compressor, improve lubrication conditions, and improve compressor efficiency. At the same time, it can prevent oil film from accumulating in the condenser and optimize the refrigeration cycle efficiency. Furthermore, the value of h1 in the compressor stator insulation frame assembly of this embodiment is larger than that in related technologies. This increases the height difference between the second frame 2 and the end face of the stator core 10, thereby increasing the pressure differential. During compressor operation, the area below the rotor core is a mixture of lubricating oil and refrigerant. A larger pressure differential facilitates the upward flow of oil and gas (refrigerant and lubricating oil), increasing the flow rate and benefiting the compressor's cooling and lubrication. Specifically, if h1 is too small, the pressure differential is small, which is not conducive to the flow of the oil-gas mixture. If h1 is too large, the motor will be closer to the lower compression components (cylinder, blades, etc.), and the second frame 2 will block the flow of the oil-gas mixture, which is also not conducive to lubrication. In this embodiment, the range of h1 is designed to be 13.9mm≤h1≤16mm, which avoids the above situation and improves the cooling and lubrication effect inside the compressor. The compressor stator insulation frame assembly with the above-described structure solves the technical problem in related technologies where poor internal refrigerant and lubricating oil flow affects the compressor's operating efficiency.

[0022] In use, the first frame 1 is the upper frame and the second frame 2 is the lower frame. During installation, the upper frame is located on the upper end face of the stator core 10 and the lower frame is located on the lower end face of the stator core 10. Lubricating oil and refrigerant flow downward from above the upper frame.

[0023] In practical implementation, the shape of the guide surface 111 can be any shape that facilitates the flow of oil and gas. For example, the shape of the guide surface 111 can include, but is not limited to, inclined surfaces, arc surfaces, and stepped surfaces. Figure 1 and Figure 2 As shown, in this embodiment, at least a portion of the guide surface 111 is an arc-shaped surface. For example... Figure 5 and Figure 6 As shown, in this embodiment, at least a portion of the guide surface 111 is inclined.

[0024] Along the axial direction of the stator core 10, the height of the second frame 2 is greater than the height of the first frame 1; and / or, along the axial direction of the stator core 10, the height of the reinforcing part 11 is less than or equal to the height of the first frame 1. Preferably, the minimum thickness h2 of the sidewalls of the first frame 1 and / or the second frame 2 is ≥ 0.8 mm. In this embodiment, the minimum thickness h2 of the sidewalls of the first frame 1 and / or the second frame 2 is designed to be greater than or equal to 0.8 mm, thereby effectively ensuring the structural strength of the first frame 1 and / or the second frame 2 and reducing the risk of deformation of the first frame 1 and / or the second frame 2.

[0025] In some optional embodiments, both the first frame 1 and the second frame 2 include an annular body portion 101 and a plurality of winding teeth 102. The plurality of winding teeth 102 are disposed on the inner wall of the body portion 101 and are arranged sequentially at intervals along the circumference of the body portion 101. A winding groove 103 is formed between any two adjacent winding teeth 102. The structure of the compressor stator insulation frame assembly satisfies at least one of the following: The compressor stator insulation frame assembly includes multiple inner teeth 104, which are correspondingly arranged at one end of multiple winding teeth 102 near the center of the compressor stator insulation frame assembly. The body portion 101 has multiple wire-passing grooves 105, with a blocking portion 106 formed between adjacent wire-passing grooves 105. This allows the windings to be shielded by the inner teeth 104 and the blocking portion 106, preventing exposure, while allowing wires to pass through the wire-passing grooves 105. In a preferred embodiment, the blocking portion 106 is arched, thus saving material.

[0026] To better shield and protect the windings, the windings are exposed. Along the axial direction of the compressor stator insulation frame assembly, the height of the blocking portion 106 is greater than or equal to the height of the inner teeth 104. The compressor stator insulation frame assembly includes multiple inner teeth 104, which are correspondingly arranged at the ends of multiple winding teeth 102 near the center of the compressor stator insulation frame assembly. The body portion 101 is provided with multiple wire-passing grooves 105, and a blocking portion 106 is formed between two adjacent wire-passing grooves 105. Along the circumference of the compressor stator insulation frame assembly, the ends of the inner teeth 104 and the ends of the blocking portions 106 are aligned. The compressor stator insulation frame assembly includes multiple inner teeth 104, which are correspondingly arranged at the ends of multiple winding teeth 102 near the center of the compressor stator insulation frame assembly. Along the axial direction of the compressor stator insulation frame assembly, the distance h3 between the inner teeth 104 and the winding teeth 102 satisfies 3mm ≤ h3 ≤ 7mm.

[0027] In this embodiment, a recessed structure 1011 is provided at the position corresponding to the winding groove 103 on the inner peripheral surface of the body portion 101, and at least a portion of the surface of the recessed structure 1011 is curved. By designing a curved recessed structure 1011 on the inner peripheral surface of the body portion 101, the use of materials can be further reduced while ensuring that the structural strength of the body portion 101 meets the requirements, which is beneficial to reducing the weight and cost of the compressor.

[0028] In addition, such as Figure 1 As shown, an embodiment of the present invention also provides a stator assembly, which includes: a stator core 10; and the above-mentioned compressor stator insulation frame assembly, wherein the first frame 1 and the second frame 2 of the compressor stator insulation frame assembly are fitted one-to-one with the two ends of the stator core 10 along the axial direction.

[0029] Specifically, the outer circumferential surface of the stator core 10 is provided with multiple tangents 100, which extend along the axial direction of the stator core 10. The first frame 1 has multiple reinforcing parts 11, which are arranged in a one-to-one correspondence with the positions of the multiple tangents 100. The refrigerant and lubricating oil are guided to the corresponding tangents 100 through the guide surface 111 of each reinforcing part 11. The guide surface 111 of the reinforcing part 11 guides the refrigerant and lubricating oil to the corresponding tangents 100. In this way, the refrigerant and lubricating oil can flow better along the tangents 100, which is beneficial to improving the flow rate of the refrigerant and lubricating oil.

[0030] Furthermore, embodiments of this utility model also provide a motor structure, which includes the stator assembly described above.

[0031] In a preferred embodiment, the guide surface 111 is inclined toward the second frame 2 along the rotation direction of the rotor of the motor structure. With this inclined arrangement, the guide surface 111 will drive the surrounding refrigerant and lubricating oil to rotate when the motor rotor rotates. During the rotation, the refrigerant and lubricating oil will flow along the guide surface 111 toward the second frame 2. This allows the oil and gas to accumulate and fall more effectively, reducing the amount of oil discharged and improving the lubrication conditions inside the compressor.

[0032] Finally, an embodiment of this utility model also provides a compressor, which includes the motor structure described above.

[0033] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: The compressor stator insulation frame assembly of this utility model includes: a first frame 1 and a second frame 2, which are used to cooperate one-to-one with the two ends of the stator core 10 along the axial direction; wherein, the outer peripheral surface of the first frame 1 is provided with a reinforcing part 11, the reinforcing part 11 protruding from the outer peripheral surface of the first frame 1, and the reinforcing part 11 has a guiding surface 111 for guiding the refrigerant and lubricating oil; when the first frame 1 is installed on the upper end of the stator core 10, the reinforcing part 11 contacts the stator core 10, and the guiding surface 111 is located at the upper end of the reinforcing part 11. 1. The side away from the stator core 10; the second frame 2 includes an annular body part 101 and multiple winding teeth 102. The multiple winding teeth 102 are all disposed on the inner wall of the body part 101. The multiple winding teeth 102 are arranged sequentially at intervals along the circumference of the body part 101. A winding groove 103 is formed between any two adjacent winding teeth 102. The distance h1 between the end face of the body part 101 and the winding teeth 102 satisfies 13.9mm≤h1≤16mm. The end face of the body part 101 is the end face of the body part 101 away from the stator core 10. The compressor stator insulation frame assembly with this structural design has a reinforcing part 11 on the outer peripheral surface of the first frame 1. In use, the first frame 1 is assembled on the upper end of the stator core 10. After the first frame 1 and the stator core 10 are engaged, the reinforcing part 11 contacts the stator core 10, thereby providing reliable support and reinforcement for the relative position between the two. On this basis, a guide surface 111 is provided on the side of the reinforcing part 11 away from the stator core 10. The guide surface 111 can guide the refrigerant and lubricating oil (hereinafter referred to as oil vapor) inside the compressor, which helps to collect and fall the oil vapor above the motor, reduce the amount of oil discharged, reduce the amount of oil mist discharged with the refrigerant, improve the retention of refrigeration oil inside the compressor, improve lubrication conditions, and improve compressor efficiency. At the same time, it can prevent oil film from accumulating in the condenser and optimize the refrigeration cycle efficiency. Furthermore, the value of h1 in the compressor stator insulation frame assembly of this embodiment is larger than that in related technologies. This increases the height difference between the second frame 2 and the end face of the stator core 10, thereby increasing the pressure differential. During compressor operation, the area below the rotor core is a mixture of lubricating oil and refrigerant. A larger pressure differential facilitates the upward flow of oil and gas (refrigerant and lubricating oil), increasing the flow rate and benefiting the compressor's cooling and lubrication. Specifically, if h1 is too small, the pressure differential is small, which is not conducive to the flow of the oil-gas mixture. If h1 is too large, the motor will be closer to the lower compression components (cylinder, blades, etc.), and the second frame 2 will block the flow of the oil-gas mixture, which is also not conducive to lubrication. In this embodiment, the range of h1 is designed to be 13.9mm≤h1≤16mm, which avoids the above situation and improves the cooling and lubrication effect inside the compressor. The compressor stator insulation frame assembly with the above-described structure solves the technical problem in related technologies where poor internal refrigerant and lubricating oil flow affects the compressor's operating efficiency.
