[0002] In the field of refrigeration equipment, the compressor, as one of the core components, plays a crucial role in the overall performance and adaptability of the machine. Existing mass-produced compressors typically consist of a cylinder block, crankshaft assembly, motor, and housing. The overall height of the compressor is essentially determined by adding the height of the motor to the height of the cylinder head.
[0003] In recent years, with the rapid development of the refrigerator industry, refrigerator manufacturers have been continuously optimizing the cabinet structure to meet market demands. Consumers' expectations for the internal capacity of refrigerators are increasing, prompting refrigerator manufacturers to strive for the ultimate utilization of space in the product design process. In the compressor selection stage, stringent requirements are often placed directly on the overall height of the compressor. Utility Model Content

[0006] In one aspect of this application, a horizontal compressor is provided, including a housing and a motor and a cylinder disposed within the housing.

The upper side of the motor is close to the top of the housing, and the lower side of the motor is close to the bottom of the housing.
[0007] Optionally, as an implementable method, a buffer is provided at the bottom of the housing to support the motor and the cylinder, and the buffer direction of the buffer is perpendicular to the rotation axis of the motor.
[0008] Alternatively, as one possible implementation, the buffer includes a plurality of buffers, which are evenly distributed in a square shape at the bottom of the housing.

[0027] Please refer to Figure 1 and Figure 2This embodiment provides a horizontal compressor 100, including a housing 110 and a motor 120 and a cylinder 130 disposed within the housing 110. The axis of the cylinder 130 is perpendicular to the rotation axis of the motor 120 on a horizontal plane. The upper side of the motor 120 is close to the top of the housing 110, and the lower side of the motor 120 is close to the bottom of the housing 110.
[0028] Specifically, this application, through its unique layout, alters the relative positional relationship between the motor 120 and the cylinder 130 compared to traditional compressors. This design fully utilizes the internal lateral space of the housing 110 to vertically arrange the motor 120 and cylinder 130, while horizontally arranging them within the housing 110. Furthermore, the motor 120 is positioned close to the upper and lower sides of the housing 110 as required, resulting in a more compact overall structure in the vertical dimension. This avoids unnecessary height increases caused by component stacking, creating conditions for reducing the overall machine height from a structural perspective.
[0029] The horizontal compressor 100 provided in this application includes a housing 110 and a motor 120 and a cylinder 130 disposed within the housing 110. The axis of the cylinder 130 is perpendicular to the rotation axis of the motor 120 in the horizontal plane. The upper side of the motor 120 is close to the top of the housing 110, and the lower side of the motor 120 is close to the bottom of the housing 110. By aligning the axis of the cylinder 130 perpendicular to the rotation axis of the motor 120, and by ensuring the motor 120 is tightly fitted against the upper and lower walls of the housing 110, this layout allows for a more rational distribution of the motor 120 and cylinder 130 within the housing 110. It fully utilizes the horizontal space, providing more possibilities for the installation and arrangement of other components, and contributing to improved overall structural compactness and stability of the compressor. Compared to traditional compressors, the overall height is significantly reduced. This makes the compressor of this application more adaptable to refrigeration equipment of different specifications.
[0030] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, a buffer 140 is provided at the bottom of the housing 110, which supports the motor 120 and the cylinder 130. The buffering direction of the buffer 140 is perpendicular to the rotation axis of the motor 120.
[0031] Specifically, when the motor 120 and cylinder 130 are running, they will generate a certain amount of vibration. The buffer 140 can effectively absorb and disperse this vibration energy, changing the vibration transmission path to a direction perpendicular to the rotation axis of the motor 120, thereby reducing the impact of vibration on the housing 110 and other components, lowering the noise level, and improving the stability and reliability of the compressor operation. Through the buffering effect of the buffer 140, the impact force experienced by the motor 120 and cylinder 130 during vibration can be reduced, extending the service life of the components and reducing maintenance costs. The buffer 140 can be a rubber buffer or a spring.
[0032] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the buffer 140 includes multiple buffers, which are evenly distributed in a square shape at the bottom of the housing 110.
[0033] Specifically, the multiple evenly distributed square buffers 140 can make the supporting force and buffering force on the motor 120 and cylinder 130 more uniform, avoiding component damage or increased vibration caused by uneven local force. This can ensure the stability of the compressor during operation and improve the overall performance of the compressor.
[0034] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, one side of the motor 120 and one side of the cylinder 130 are respectively close to the corresponding side wall of the housing 110.
[0035] Specifically, the motor 120 and cylinder 130 of this application are located close to the side wall of the housing 110, making full use of the edge space inside the housing 110, reducing unnecessary space waste, and further reducing the overall volume of the compressor, making it more suitable for use in refrigeration equipment with limited space.
[0036] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the cylinder 130 includes a cylinder body 131 and a piston 132 disposed in the cylinder body 131. A piston rod 133 is rotatably connected to the piston 132. The motor 120 drives the piston 132 to perform reciprocating linear motion in the cylinder body 131 through the piston rod 133.
[0037] The motor 120 drives the piston rod 133, which in turn drives the piston 132 to reciprocate linearly within the cylinder 131, thereby compressing the refrigerant. This effectively converts the rotational motion of the motor 120 into the linear motion of the piston, ensuring the normal operation of the compressor.
[0038] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the motor 120 includes a stator 121 and a rotor 122. The rotation center of the rotor 122 has a through hole, and a crankshaft 123 is inserted into the through hole. The crankshaft 123 has an eccentric part 1231, which extends out of the motor 120 and is rotatably connected to the piston rod 133.
[0039] Specifically, this application achieves efficient energy transfer by using the eccentric portion 1231 of the crankshaft 123 to rotate with the piston rod 133, thus accurately converting the rotational motion of the rotor 122 of the motor 120 into the linear motion of the piston rod 133. This motion conversion method is simple and reliable, reduces energy loss in intermediate stages, and improves the compressor's efficiency. Inserting the crankshaft 123 into the through-hole of the rotor 122 makes the structure of the motor 120 and crankshaft 123 more compact, reducing space requirements and improving the stability of the entire transmission system.
[0040] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, it also includes a connecting flange 150, which has a cylinder 130 mounting position and a crankshaft 123 mounting position. The cylinder 130 is mounted through the cylinder 130 mounting position, and the crankshaft 123 is mounted through the crankshaft 123 mounting position.
[0041] Specifically, the connecting flange 150 has a cylinder 130 mounting position and a crankshaft 123 mounting position. The cylinder 130 is mounted through the cylinder 130 mounting position, and the crankshaft 123 is mounted through the crankshaft 123 mounting position. The connecting flange 150 serves to connect and fix the cylinder 130 and the crankshaft 123, ensuring their relative position and movement relationship.
[0042] The connecting flange 150 provides accurate positioning and reliable fixing for the installation of cylinder 130 and crankshaft 123. The mounting positions for cylinder 130 and crankshaft 123 allow for easy installation of both components, ensuring precise fit and improving installation efficiency and quality. The connecting flange 150 effectively connects cylinder 130 and crankshaft 123 together, forming a stable integrated structure. This reduces relative displacement and vibration between cylinder 130 and crankshaft 123 during operation, improving the reliability and stability of the compressor.
[0043] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3As shown, the cylinder 130 mounting position has a piston rod through hole 151 through which the piston rod 133 passes, and the crankshaft 123 mounting position has a crankshaft through hole 152 through which the crankshaft 123 passes. The extending directions of the piston rod through hole 151 and the crankshaft through hole 152 are perpendicular to each other.
[0044] Specifically, the piston rod through-hole 151 and crankshaft through-hole 152 of this application extend in perpendicular directions, allowing the piston rod 133 and crankshaft 123 to move freely within their respective holes and accurately transmit motion. This structural design conforms to the working principle of a compressor, ensuring that the rotational motion of the motor 120 can be smoothly converted into the linear motion of the piston, thus realizing the compression function of the compressor.
[0045] This vertical through-hole design further optimizes the structural layout of the connecting flange 150, making the entire compressor structure more compact and reasonable, reducing unnecessary space occupation and improving space utilization.
[0046] In one possible embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the housing 110 is provided with an air inlet 111 and an air outlet 112, and the air outlet 112 and the air outlet of the cylinder 130 are connected through an air outlet pipe 113.
[0047] Specifically, inlet 111 is used to draw in refrigerant, outlet 112 is used to discharge compressed refrigerant, and outlet pipe 113 ensures that the refrigerant can be smoothly discharged from cylinder 130 to the outside of housing 110. The arrangement of inlet 111 and outlet 112, and the connection of outlet pipe 113, constitute the refrigerant circulation channel of the compressor. Refrigerant is drawn in through inlet 111, compressed by cylinder 130, and discharged from outlet 112 through outlet pipe 113, realizing the circulation of refrigerant and ensuring the normal cooling function of the refrigeration equipment. The reasonable design of the inlet and outlet structure ensures the smooth flow of refrigerant, reduces flow resistance, improves the circulation efficiency of refrigerant, thereby improving the cooling efficiency of the compressor and reducing the energy consumption of the refrigeration equipment.

This refrigeration device has the same structure and beneficial effects as the compressor described in the foregoing embodiments. The structure and beneficial effects of the compressor have been described in detail in the foregoing embodiments and will not be repeated here.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
