Description

Technical Field

[0001] This utility model relates to the field of compressor cylinder seat technology, specifically a cylinder seat structure that can reduce its height. Background Technology

[0002] For miniaturized compressors, effectively reducing the overall height of the compressor housing provides more refrigeration space for refrigerator and freezer manufacturers, greatly increasing installation convenience. The compressor's height largely depends on the cylinder head height. To ensure electrical strength, the stator feet under the cylinder head ribs accommodate the motor coils; the cylinder head height on the cylinder head ribs depends on the maximum cylinder diameter. Therefore, the height of the motor coils and the maximum cylinder diameter determine the overall height of the cylinder head, thus affecting the overall height of the compressor. Based on this, appropriately reducing the compressor's height through the structural design and clever layout of the cylinder head becomes an essential choice in the design process.

[0003] In current common solutions, to reduce the compressor height, the height of the motor coil is controlled to ensure that the stator foot height of the cylinder block is not too high. However, excessively low coil dimensions drastically increase the risk of wire damage and breakage during the shaping process of the motor enameled wire. Furthermore, reducing the cylinder bore diameter and designing a smaller cylinder face height is also a common method. However, while this method can appropriately reduce the overall height, it introduces limitations in cylinder block application. This structure cannot accommodate larger cylinder bores, and due to the limitation of cylinder working volume, it cannot provide greater cooling capacity. Additionally, an excessively small cylinder face restricts the volume of the cylinder head and cylinder cover, thus affecting the compressor's starting performance.

[0004] Therefore, since the existing requirements are not met, a cylinder seat structure with a reduced height has been proposed. Utility Model Content

[0005] The purpose of this invention is to provide a cylinder seat structure that can reduce its height, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cylinder seat structure with a reduced height, comprising: a cylinder seat, the cylinder seat including a flat cylinder head and a cylinder tail, a cylinder head mounted on one end of the cylinder head, a lower end of a cylinder surface provided on the lower surface of the cylinder seat, a lower bottom of a rib plate provided at the front end of the lower end of the cylinder surface, a shoulder provided at the middle position of the cylinder seat, an umbrella-shaped cone provided below the shoulder, and a rotor mounted below the cylinder seat.

[0007] Preferably, the distance between the lower end of the cylinder surface and the lower bottom of the rib plate is 6-8mm, and the distance between the shoulder and the lower bottom of the rib plate is 3-5mm.

[0008] Preferably, the lower surface of the bottom of the rib plate is provided with an arc-shaped reinforcing rib extending to the cylinder head and cylinder tail.

[0009] Preferably, the upper surface of the shoulder is provided with an annular reinforcing rib, and the two ends of the annular reinforcing rib extend to the cylinder head and cylinder tail positions respectively.

[0010] Preferably, an axle hole is provided at the middle position of the umbrella-shaped cone, the cone surface of the umbrella-shaped cone is inverted and the thickness is 4-6mm, and an X-shaped rib is provided on the outer wall of the umbrella-shaped cone. One end of the X-shaped rib is connected to the bottom of the rib plate and the other end of the X-shaped rib is connected to the axle hole.

[0011] Preferably, the upper surface of the rotor is provided with a rotor aluminum end ring, a stator coil is provided between the rotor and the cylinder base, and the lower surface of the annular reinforcing rib and the bottom of the rib plate are provided with insulating gaskets for contacting the stator coil.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) In this utility model, on the basis of the traditional structure, the cylinder head is set to be flat while ensuring the height of the cylinder surface, so that the width of the cylinder head is greater than the height, so that the cylinder surface is not reduced, ensuring that the cylinder head volume is large enough without affecting the starting performance of the compressor. Without reducing the maximum cylinder diameter of the cylinder surface and increasing the difficulty of motor coil shaping, the limited area between the rotor and the cylinder seat is fully utilized during assembly, making the overall assembly structure more compact and achieving the effect of reducing the overall height of the machine through the design of the cylinder seat.

[0014] (2) In this utility model, arc-shaped reinforcing ribs are provided in the cylinder head and cylinder tail areas at the bottom of the rib plate. An annular reinforcing rib is designed above the recessed area of ​​the shaft shoulder. The annular reinforcing rib extends to the cylinder head and cylinder tail areas of the cylinder seat. In addition, an X-shaped rib is designed to support the shaft hole reinforcement strength. Its upper end is connected to the bottom of the rib plate of the cylinder seat, and its lower end is connected to the shaft hole of the cylinder seat. During assembly, the upper end of the X-shaped rib is located in the area between the rotor aluminum end ring and the inner diameter of the stator coil, and the lower end is located in the area inside the countersunk hole of the rotor aluminum end ring. Through the above structure, the strength of the cylinder seat itself is effectively improved, and the area between the cylinder seat and the rotor is reasonably improved, effectively reducing the overall height of the machine.

[0015] (3) In this utility model, in order to ensure electrical insulation strength, a contoured insulating pad with a skirt is placed below the bottom of the stiffener plate. During assembly, the lower end face of the annular reinforcing rib is separated from the inner diameter of the stator coil by the lower skirt of the insulating pad, and the position of the arc-shaped reinforcing rib at the bottom of the stiffener plate is separated from the upper end face of the stator coil by the contoured insulating pad, thereby ensuring insulation between the cylinder seat and the motor.
