Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to a compressor and a refrigeration device. Background Art

[0002] As the heart of the refrigeration system, the efficiency, vibration and noise levels of refrigerator compressors during operation are crucial to the user experience. In the design of the compressor, a high-pressure chamber is usually combined with a single-path internal discharge pipe for exhaust. The high-pressure chamber, also known as the exhaust buffer, is mainly responsible for regulating the pressure of gas flow and plays a certain throttling role; while the internal discharge pipe is used to discharge high-pressure gas. These two design elements jointly affect the working performance and stability of the compressor.

[0003] Specifically, a stronger throttling effect can effectively reduce the pulsation in the gas flow, thereby reducing the noise generated when the compressor is running. However, this process will also bring greater flow resistance, resulting in additional energy loss, the so-called throttling loss. This loss will directly affect the refrigeration efficiency of the compressor and may cause a decrease in refrigeration capacity. Therefore, in the design process of the compressor, it is necessary to find a balance point to ensure good noise control without affecting its refrigeration efficiency. Summary of the invention

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0051] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0052] In the design of compressors, a high-pressure chamber is usually combined with a single-path internal discharge pipe for exhaust. The high-pressure chamber, also known as the exhaust buffer, is mainly responsible for regulating the pressure of the gas flow and plays a certain throttling role; while the internal discharge pipe is used to discharge the high-pressure gas. These two design elements jointly affect the working performance and stability of the compressor. Specifically, a strong throttling effect can effectively reduce the pulsation in the gas flow, thereby reducing the noise generated when the compressor is running. However, this process also brings greater flow resistance, resulting in additional energy loss, the so-called throttling loss. This loss will directly affect the refrigeration efficiency of the compressor and may cause a decrease in refrigeration capacity. Therefore, in the design process of the compressor, it is necessary to find a balance point that ensures good noise control without affecting its refrigeration efficiency.

[0053] The present invention proposes a compressor, aiming to provide a compressor which can reduce throttling loss and increase refrigeration capacity, thereby improving the energy efficiency of the compressor.

[0054] See also Figures 1 to 3In one embodiment of the present invention, the compressor 100 includes a housing, a motor, a crankshaft, a crankcase 10, and an exhaust pipe 5. The motor is arranged in the housing, and the motor has an output shaft; the crankshaft is connected to the output shaft to be driven to rotate by the motor; the crankcase 10 is arranged in the housing, and the crankcase 10 includes a compression cylinder 8, a first inner row of pipes 3 and a second inner row of pipes 4. The compression cylinder 8 includes a working chamber and a piston movably mounted in the working chamber. The piston is connected to the crankshaft through a connecting rod transmission to be moved in the crankshaft. The piston is driven to move during movement, and the compression cylinder 8 has an air inlet and an exhaust port; the crankcase 10 includes a first high-pressure chamber 1 and a second high-pressure chamber 2, the first high-pressure chamber 1 is connected to the exhaust port of the compression cylinder 8, and the first high-pressure chamber 1 and the second high-pressure chamber 2 are connected to each other; the first end of the first inner row pipe 3 is connected to the first high-pressure chamber 1, and the first end of the second inner row pipe 4 is connected to the second high-pressure chamber 2; the exhaust pipe 5 is connected to the second ends of the first inner row pipe 3 and the second inner row pipe 4.

[0055] It should be noted that the shell is the external protective cover of the compressor, which not only provides mechanical support, but also plays a sealing role to prevent external impurities from entering the compressor and maintain internal pressure.

[0056] The motor is the power source that drives the compressor to work. It generates kinetic energy through rotation, and then drives the crankshaft to move.

[0057] The crankshaft is a key component connecting the motor and the compression cylinder 8, and it converts the rotational motion of the motor into the reciprocating linear motion of the piston, thereby achieving the compression of the refrigerant.

[0058] The crankshaft is usually designed with an eccentric or connecting rod mechanism to ensure smooth and efficient motion conversion.

[0059] The compression cylinder 8 is where the refrigerant is actually compressed. The refrigerant is sucked in and discharged after being compressed.

[0060] It should be noted that the compressor 100 may be a single-cylinder compressor.

[0061] The crankcase is the space that houses the crankshaft and other related moving parts. It provides a controlled environment to support the rotational motion of the crankshaft and facilitates the operation of the lubrication system.

[0062] It can be understood that the first high-pressure chamber 1 is directly connected to the exhaust port of the compression cylinder 8 to receive the high-pressure gas from the compression cylinder 8. The second high-pressure chamber 2 is interconnected with the first high-pressure chamber 1 to further process the high-pressure gas flowing in from the first high-pressure chamber 1.

[0063] One end of the first inner row of pipes 3 is connected to the first high-pressure chamber 1 , and the other end is connected to the exhaust pipe 5 , providing a discharge path for the high-pressure gas.

[0064] One end of the second inner row of pipes 4 is connected to the second high-pressure chamber 2 , and the other end is also connected to the exhaust pipe 5 , providing a second exhaust path for the high-pressure gas.

[0065] The exhaust pipe 5 eventually discharges the high-pressure gas processed by the first inner row of pipes 3 and the second inner row of pipes 4 out of the compressor.

[0066] In the prior art, the exhaust port of the compression cylinder 8 flows from the first high-pressure chamber 1 into the second high-pressure chamber 2, and then flows into the exhaust pipe 5 through the second inner exhaust pipe 4, so that the exhaust path has only a single line.

[0067] The dual-path design of the first inner row of tubes 3 and the second inner row of tubes 4 in the present invention enables the high-pressure gas discharged from the compressor to have two discharge paths, thereby alleviating the flow resistance of a single path, reducing throttling losses, and also helping to improve the gas discharge efficiency, so that more gas can be discharged quickly and more gas can complete the cycle in a short time, thereby improving the refrigeration capacity of the compressor.

[0068] It should be noted that the lengths of the first inner row of pipes 3 and the second inner row of pipes 4 can be appropriately adjusted according to the compressor model, internal space layout, performance preference, etc.

[0069] It can be understood that providing dual-path discharge, reducing flow resistance and uniform gas distribution can reduce the noise level when the compressor is running.

[0070] In the technical solution of the present invention, the exhaust port of the compression cylinder 8 is connected to the first high-pressure chamber 1. The high-pressure gas from the first high-pressure chamber 1 can flow to the second high-pressure chamber 2 connected to the first high-pressure chamber 1, and then flow to the exhaust pipe 5 through the first inner row pipe 3. By adding the second inner row pipe 4 between the first high-pressure chamber 1 and the exhaust pipe 5, the high-pressure gas discharged from the exhaust port of the compression cylinder 8 to the first high-pressure chamber 1 can be partially converged to the exhaust pipe 5 through the second inner row pipe 4, thereby increasing the total exhaust cross-sectional area, and the flow resistance of the fluid when passing through is small, and the pressure drop and energy loss are also small, thereby increasing the gas discharge channel, so that more gas can be discharged from the high-pressure chamber in a shorter time, thereby indirectly improving the refrigeration capacity of the compressor.

[0071] For further information, see Figure 3 In this embodiment, the inner diameter of the first inner row tubes 3 is set to be smaller than the inner diameter of the second inner row tubes 4.

[0072] If the inner diameter of the first inner row tube 3 is set too large, the resistance to gas flow will be reduced, so that the flow speed of gas between the first high-pressure chamber 1 and the first inner row tube 3 will be accelerated, resulting in intensified gas pulsation, thereby increasing the vibration and noise of the compressor.

[0073] It is understandable that if the inner diameter of the first inner row pipe 3 is too large, it will also lead to insufficient back pressure formed in the first high-pressure cavity 1. Back pressure is an important factor in maintaining the stable flow of high-pressure gas. Insufficient back pressure will make the gas flow unstable and affect the performance of the compressor. In the present invention, since the inner diameter of the first inner row pipe 3 is relatively small, the flow resistance of the gas in the first inner row pipe 3 can be increased, thereby forming a certain back pressure in the first high-pressure cavity 1 to stabilize the flow of high-pressure gas, reduce gas pulsation, and reduce noise. In addition, the inner diameter of the second inner row pipe 4 is relatively large, which can reduce the flow resistance of the gas in the second inner row pipe 4, ensure that the high-pressure gas can be smoothly discharged from the second high-pressure cavity 2, and reduce throttling losses.

[0074] In some embodiments, see Figures 1 to 3 The compressor 100 further includes a manifold 6 , which has three interfaces 61 , two of which are respectively connected to the second ends of the first inner row of tubes 3 and the second inner row of tubes 4 , and the other interface 61 is connected to the exhaust pipe 5 .

[0075] The positions and directions of the three interfaces 61 can be adjusted according to actual needs, which is convenient for installation and maintenance, provides higher connection flexibility, and reduces installation time and cost.

[0076] The manifold 6 can be a plastic pipe, which has a low cost and does not require a separate mold for the exhaust pipe 5. The standardized design improves production efficiency and ensures consistency in product quality.

[0077] Specifically, in this embodiment, the manifold 6 is bonded or hot-melt-connected to the second ends of the first inner row of tubes 3 and the second inner row of tubes 4 ; and / or, the manifold 6 is bonded or hot-melt-connected to the exhaust pipe 5 .

[0078] It is understood that bonding is a method of joining two or more surfaces together by using an adhesive (glue). The adhesive can be in liquid, paste or solid form and cures through chemical reaction or physical change to form a strong connection.

[0079] Hot melt connection is a method of melting the surfaces of two or more thermoplastic materials by heating, and then cooling and solidifying to form a strong connection. This method is commonly used to connect plastic pipes and fittings.

[0080] Through bonding, the adhesive can fill tiny gaps to form a seamless connection, reduce the risk of gas leakage, and thus form a good seal. In addition, the bonding method is suitable for connecting a variety of materials and can be flexibly applied to different design requirements.

[0081] Through hot melt connection, a seamless connection is formed, which can also reduce the risk of gas leakage and ensure the airtightness of the system. At the same time, the connection parts of hot melt connection have high durability and can maintain stable performance for a long time.

[0082] Specifically, in some embodiments, the manifold 6 is configured as a plastic tube. Thus, the manifold 6 can be connected to the exhaust pipe 5 and the first inner row of tubes 3 and the second inner row of tubes 4 by hot-melt connection to form a stable structure and reduce production costs.

[0083] Specifically, see Figure 4 In other embodiments, the exhaust pipe 5 includes two connecting sections 51 and a confluence section 52, one end of the two connecting sections 51 is connected to the confluence section 52, and the other end is respectively connected to the second end of the first inner row pipe 3 and the second inner row pipe 4.

[0084] It can be understood that one end of one of the connecting sections 51 is connected to the second end of the first inner row of pipes 3, one end of the other connecting section 51 is connected to the second end of the second inner row of pipes 4, and the other ends of the two connecting sections 51 are both connected to the confluence section 52, which eventually merges the two streams of gas and discharges them from the compressor. The design of the two connecting sections 51 allows the gas to have enough time to be evenly distributed before confluence, reduces turbulence at the entrance of the confluence section 52, and further reduces noise.

[0085] The two connecting sections 51 and the confluence section 52 are integrally formed to form a complete structure of the exhaust pipe 5. The integral molding manufacturing process is relatively simple, which reduces welding and assembly steps and reduces manufacturing costs. The seamless design reduces the workload of maintenance and repair and extends the service life of the exhaust pipe 5. Without the interference of seams and welding points, the gas converges more evenly in the confluence section 52, reducing turbulence and pulsation, and further improving the stability of the gas flow.

[0086] Specifically, in some embodiments, the first inner row of tubes 3 and / or the second inner row of tubes 4 are configured as plastic tubes. Plastic tubes are usually made of thermoplastics (such as polyethylene, polypropylene, etc.), and have the advantages of good corrosion resistance, light weight, low cost, etc. When connected to the manifold 6, hot melt connection can be adopted.

[0087] In this example, see Figure 1 and Figure 2The first high-pressure cavity 1 and the second high-pressure cavity 2 are both provided with openings; the compressor 100 also includes two cover bodies 7, and the two cover bodies 7 are respectively covered at the openings of the first high-pressure cavity 1 and the second high-pressure cavity 2; the first inner row of tubes 3 and the second inner row of tubes 4 are respectively bonded or hot-melt connected to the corresponding cover bodies 7.

[0088] It should be noted that the two cover bodies 7 are configured as metal parts, and the two cover bodies 7 can be connected to the crankcase via hexagonal screws.

[0089] The cover 7 is tightly covered at the opening of the high-pressure cavity to ensure that the high-pressure gas does not leak, thereby improving the sealing of the system. The first inner tube 3 and the second inner tube 4 are fixed to the corresponding cover 7 by bonding or hot-melt connection to form a seamless connection, further improving the sealing.

[0090] The cover body 7 is connected to the first inner tube row 3 and the second inner tube row 4 by bonding or hot melting, ensuring that the connection parts of the first inner tube row 3 and the second inner tube row 4 and the cover body 7 are not easy to fall off under the impact of high-pressure gas. The seams in traditional welding or mechanical connection can be eliminated, the risk of gas leakage can be reduced, the reliability of the system can be improved, the complex steps in the manufacturing process can be reduced, and the production efficiency can be improved.

[0091] It should also be noted that if maintenance or replacement of parts is required, the connection methods of bonding and hot melt connection are relatively easy to disassemble, convenient for inspection and maintenance, reducing the maintenance frequency and workload, and reducing maintenance costs.
