DETAILED DESCRIPTION

[0027] In order to make the person skilled in the art better understand the present application scheme, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should be within the scope of protection of the present application.

[0028] Please refer to Figures 1 to 5 As shown in the figure, according to the embodiment of the utility model, the utility model provides a kind of compressor, it include: cylinder seat 1, piston compression structure 2 and rotor compression structure 3, piston compression structure 2 is installed on cylinder seat 1;Rotor compression structure 3 is detachably arranged on cylinder seat 1;To compress refrigerant by piston compression structure 2 and / or rotor compression structure 3;Wherein, cylinder seat 1 is equipped with the suction passage 10 for refrigerant flow, and the suction end of piston compression structure 2 and the suction end of rotor compression structure 3 are all connected with the suction passage 10 of cylinder seat 1.

[0029] It can be seen that the compressor provided by the utility model, comprising a cylinder base 1, a piston compression structure 2 and a rotor compression structure 3, the piston compression structure 2 is installed on the cylinder base 1, and the rotor compression structure 3 is detachably arranged on the cylinder base 1, the cylinder base 1 is provided with a suction passage 10 for refrigerant circulation, the suction passage 10 of the cylinder base 1 is connected with the suction end of the piston compression structure 2 and the suction end of the rotor compression structure 3 respectively, so that the refrigerant flowing into the suction passage 10 of the cylinder base 1 flows to the suction end of the piston compression structure 2 and the suction end of the rotor compression structure 3 respectively, and the piston compression structure 2 and the rotor compression structure 3 simultaneously compress the refrigerant. Therefore, by arranging the piston compression structure 2 and the rotor compression structure 3, the refrigerant can be double compressed at the same time. This combined compressor significantly improves the cooling capacity of the compressor and better meets the large-capacity or high-efficiency refrigeration demand, thereby improving the refrigeration capacity of the compressor. The rotor compression structure 3 is detachably installed on the cylinder base 1, thereby realizing flexible selection of single-cylinder compression and double-cylinder compression. When single-cylinder compression is needed, the rotor compression structure 3 is only removed from the cylinder base 1, at this time, the refrigerant is compressed only by the piston compression structure 2, that is, the single-cylinder compression mode is realized. When double-cylinder compression is needed, the rotor compression structure 3 is installed back on the cylinder base 1, and the refrigerant enters the piston compression structure 2 and the rotor compression structure 3 for compression at the same time, thereby realizing the double-cylinder compression mode. This design not only improves the flexibility of the compressor, but also enables the switching of the compression mode according to the actual demand, further improving the use efficiency and adaptability of the compressor. At the same time, the suction end of the piston compression structure 2 and the suction end of the rotor compression structure 3 are connected with the suction passage 10 of the cylinder base 1, and when any one of the piston compression structure 2 and the rotor compression structure 3 in the compressor fails, the other one can continue to work, thereby realizing the redundancy design and ensuring the continuity and reliability of the system. The compressor of the utility model effectively solves the technical problem that the single-cylinder compressor for a refrigerator in the prior art has limited cooling capacity and is difficult to meet higher refrigeration demand.

[0030] Further, the compressor further comprises a shell structure 6, the shell structure 6 is provided with a mounting cavity, and the cylinder base 1, the piston compression structure 2 and the rotor compression structure 3 are arranged in the mounting cavity.

[0031] Further, the exhaust end of the piston compression structure 2 and the exhaust end of the rotor compression structure 3 are both in communication with a condenser in the refrigeration device. With such a structure, by connecting the exhaust end of the piston compression structure and the exhaust end of the rotor compression structure to the same condenser, a unified exhaust path is achieved, which effectively simplifies the exhaust route, thereby reducing the pressure loss and heat loss of the refrigerant during transmission, ensuring that the high-pressure refrigerant can efficiently enter the condenser for the next step of processing. The exhaust end of the piston compression structure 2 and the exhaust end of the rotor compression structure 3 being in communication with the condenser in the refrigeration device helps to increase the exhaust capacity of the compressor, thereby improving the overall refrigeration capacity and working efficiency of the system.

[0032] Further, the compression part of the piston compression structure 2 is connected to the compression part of the rotor compression structure 3, so that the compression part of the piston compression structure 2 is driven to move by the compression part of the rotor compression structure 3, so that the piston compression structure 2 and the rotor compression structure 3 simultaneously compress the refrigerant.

The exhaust muffling chamber 4 is used to collect the refrigerant compressed by the piston compression structure 2 and the rotor compression structure 3 and to perform muffling treatment on the collected refrigerant. By using such a structure, the refrigerant from the piston compression structure 2 and the rotor compression structure 3 is collected through the exhaust muffling chamber 4, which can effectively balance the flow of the refrigerant, so that the refrigerant from the two sources is fully mixed before entering the condenser, thereby reducing the turbulence and vortex effect and improving the flow efficiency. This process increases the exhaust capacity of the compressor and improves the overall refrigeration capacity and working efficiency of the system. At the same time, the design of the exhaust muffling chamber 4 helps to improve the uniformity of the refrigerant temperature entering the condenser, enhances the heat exchange efficiency, and further improves the condensing effect. The intake end of the exhaust muffling chamber 4 is connected with the exhaust end of the piston compression structure 2 and the exhaust end of the rotor compression structure 3 respectively, and the exhaust end is connected to the condenser. This design effectively simplifies the exhaust route, reduces the pressure loss and heat loss of the refrigerant during transmission, and ensures that the high-pressure refrigerant can enter the condenser for subsequent processing efficiently. In addition, the exhaust muffling chamber can also absorb and attenuate the high-frequency noise generated by the piston compression structure 2 and the rotor compression structure 3 during the exhaust process, significantly reducing the noise level during the operation of the compressor. At the same time, the muffling chamber helps to balance the pressure fluctuation during the exhaust process of the two compression structures, reduces vibration and mechanical impact, provides a smoother exhaust flow, thereby further reducing noise, improving the user experience, and reducing the noise impact on the environment.

By adopting such a structure, the movement of the rotor compression structure 3 and the piston compression structure 2 is integrated by connecting the rotor 311 and the piston 211, and then the rotor compression structure 3 and the piston compression structure 2 can work synchronously. This design enables the rotor compression structure 3 and the piston compression structure 2 to double compress refrigerant at the same time, thereby significantly improving the cooling capacity of the compressor and better meeting the large-capacity or high-efficiency refrigeration requirements.

[0037] Optionally, the first suction port of the rotor cylinder 31 is communicated with the suction passage 10 of the cylinder block 1. The refrigerant enters the compression space of the rotor cylinder 31 through the first suction port of the rotor cylinder 31.

With such a structure, the oscillation of the rotor 311 is directly transmitted to the piston 211 through the connecting rod slider 32, achieving efficient energy transmission. This direct linkage reduces the number of intermediate transmission components, reduces energy loss, and improves the overall efficiency of the system. The connecting rod slider 32 ensures the synchronous operation of the rotor compression structure and the piston compression structure, enabling the two compression mechanisms to work together and enhance the compression effect.

[0042] Optionally, the end of the connecting rod slider 32 away from the rotor 311 is fixedly connected with the piston 211 through a piston pin.

[0043] Specifically, as shown in Figure 2 The rotor cylinder 31 further comprises a rotor cylinder body 312, the rotor cylinder body 312 is provided with an active space 310 and a slider groove 3120 communicating with the active space 310, the slider groove 3120 extends along the moving direction of the piston 211; the rotor 311 is swingably arranged in the active space 310, the end of the connecting rod slider 32 close to the rotor 311 passes through the slider groove 3120 and is hinged with the rotor 311, and at least part of the connecting rod slider 32 is movably arranged in the slider groove 3120 along the extension direction of the slider groove 3120. With such a structure, the slider groove 3120 plays a guiding role, and can accurately guide the movement of the connecting rod slider 32, ensuring that the connecting rod slider 32 moves along the designed trajectory, thereby effectively converting the oscillation of the rotor 311 into the linear reciprocating motion of the piston 211. This design improves the efficiency of energy transmission and reduces mechanical loss. At the same time, the slider groove 3120 limits the freedom of movement of the connecting rod slider 32, preventing unnecessary lateral deviation or tilting, and maintaining the stability of the entire system.

[0044] Optionally, the inner wall of the active space 310 and the outer wall of the rotor 311 form a compression space of the rotor cylinder 31.

The eccentric part of the crank structure 5 can accurately control the swing angle and frequency of the rotor 311, ensuring that each compression stroke can fully utilize the swing energy of the rotor, thereby enhancing the compression ratio.
