Description

Technical Field

[0001] This utility model relates to the field of refrigeration compressors, and specifically to a compressor with an exhaust hose assembly. Background Technology

[0002] During the operation of a refrigerator compressor, the piston moves inside the cylinder bore to draw in, compress, and expel gas. The expelled gas enters the cylinder head cavity through the exhaust port, then the exhaust pipe, and finally exits the compressor. In this process, the exhaust pipe connects the compressor core and housing. Besides expelling the compressed, high-temperature, high-pressure gas from the compressor, it also transfers heat to the compressor cavity and transmits compressor vibrations. Currently used metal exhaust pipes offer advantages in shaping and welding processes, but they have limitations in heat transfer and vibration control.

[0003] Chinese Patent Publication No. CN205779565U, Publication Date: December 7, 2016, discloses a patent entitled "A Combination of a Refrigeration Compressor Silencer and Frame." This patent discloses a refrigeration compressor silencing chamber and frame assembly, comprising a frame. The front outlet and rear inlet of the compressor exhaust pipe are respectively connected to one side and the other side of the frame. A bridge-type silencing chamber connects the front outlet and rear inlet of the exhaust pipe. The exhaust pipe in this patent is not a flexible exhaust hose but is made of metal, which may impose certain limitations on heat transfer and vibration. Utility Model Content

[0004] This invention provides a compressor with an exhaust hose assembly. By setting the exhaust hose assembly, heat from the compressor core is blocked, improving the heat insulation effect and reliability, and making the vibration reduction effect during exhaust more significant.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a compressor with an exhaust hose assembly, including a silencing chamber, both the silencing chamber and the exhaust pipe having a welded pipe at one end, the welded pipes of the two being connected by an exhaust hose, and the exhaust hose and the welded pipe being connected by a clamp; the clamp is a cylindrical shell open at both ends, with several clamping blocks at one end, the clamping blocks being bent inward into an L-shape, the ends of the clamping blocks having an arc surface facing the inside of the clamp, the clamp opening along the generatrix, a first bend on one side of the opening, a clearance hole on the first bend, and a second bend passing through the clearance hole. This blocks heat from the compressor core, making the vibration reduction effect during exhaust more significant. The exhaust hose has a simpler shape, a shorter exhaust path, and uses less material. Due to the inherent properties of the material, the exhaust hose has better heat insulation; greater damping, and improved vibration reduction effect. The exhaust hose can be thermoformed, making it less prone to deformation after forming and highly reliable.

[0006] Preferably, the exhaust hose is made of plastic, and its connection to the welded pipe is an embedded interference fit. The exhaust hose material is a high-pressure resistant and oil-incompatible plastic component. This connection method not only ensures a tight connection between the exhaust hose and the welded pipe, improving the reliability and sealing of the connection, but also, the plastic material of the exhaust hose has good flexibility and corrosion resistance, enabling it to adapt to different working environments and extending its service life. The high-pressure resistant characteristic allows the exhaust hose to work stably under high-pressure environments without rupturing or deforming due to excessive pressure; the oil incompatibility ensures that the hose will not undergo a chemical reaction when in contact with lubricating oils or other oily substances, thereby avoiding hose aging and damage, further enhancing system safety.

[0007] Preferably, the silencing chamber and exhaust pipe are located on opposite sides of the frame, and the exhaust hose is L-shaped. The wall thickness of the exhaust hose ranges from 0.1-10mm, and the length ranges from 80-300mm; the exhaust hose is cylindrical, and its bending shape can be adapted to the size and shape of the crankcase. The L-shaped exhaust hose effectively utilizes space, making the compressor structure more compact and facilitating installation and maintenance. Simultaneously, this layout helps reduce resistance during the exhaust process, improves exhaust efficiency, and reduces energy consumption. By rationally controlling the wall thickness and length, the weight of the exhaust hose can be minimized while ensuring its strength and performance, thus reducing material costs. The cylindrical shape and adaptable bending design allow the exhaust hose to better adapt to different installation environments, improving its versatility and flexibility.

[0008] Preferably, several clamping blocks are symmetrically arranged along the central axis of the clamp, with the side of the clamping block closest to the central axis serving as the clamping surface. One end of the clamping block is flush with the wall of the clamp, while the other end is perpendicular to the wall of the clamp. The side of the clamping block with the perpendicular end facing inward is the clamping surface. The symmetrically arranged clamping blocks can apply pressure evenly, ensuring the stable fixation of the exhaust hose on the welded pipe and preventing hose damage or loosening due to excessive local pressure, thereby improving connection stability and reliability.

[0009] Preferably, the clamping surface is an arc surface, perpendicular to the central axis of the clamp. Several clamping surfaces are arranged opposite each other along the central axis of the clamp. The arc surface of the clamping surface can better fit the outer wall of the exhaust hose, increasing the contact area and improving the clamping effect. The oppositely arranged clamping surfaces can form a stable clamping structure, further enhancing the fixing effect of the exhaust hose and preventing it from shifting during operation.

[0010] Preferably, the first and second bends are arranged in opposite directions. In use, the first and second bends are bent towards each other, the clamp opens along its opening, the exhaust hose is placed inside the clamp, the clamping face is aligned with the outer wall of the exhaust hose, and both ends of the exhaust hose are clamped to the outer walls of the two welded pipes. This design allows the clamp to be quickly opened and closed with a simple bending operation, facilitating the installation and removal of the exhaust hose. Simultaneously, the oppositely oriented bends provide better elastic support, ensuring that the clamp tightly holds the exhaust hose after closing.

[0011] Preferably, the second bend is provided along the wall surface of the clamp, and the arc angle is the same as the curvature of the cylindrical wall surface of the clamp. This design ensures that the second bend fits tightly against the wall surface of the clamp, improving the overall structural strength and stability of the clamp. At the same time, the same arc angle ensures that the clamp maintains uniform elastic deformation during opening and closing, avoiding local stress concentration and extending the service life of the clamp.

[0012] Preferably, the second bend is disposed within the clearance hole, and the width of the second bend is smaller than the width of the clearance hole. This smaller width ensures flexibility and operability of the clamp during installation and removal, facilitating operation.

[0013] Preferably, a crankcase is provided between the muffler and the exhaust pipe.

[0014] Preferably, the clamping block contacts the exhaust hose to secure it to the outer wall of the welded pipe. This direct contact provides a stable clamping force, ensuring the exhaust hose is firmly fixed to the welded pipe. This design not only improves connection reliability but also prevents the exhaust hose from loosening or falling off during operation due to vibration or pressure changes, thus guaranteeing the normal operation of the compressor.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a compressor with an exhaust hose assembly. By setting the exhaust hose assembly, heat from the compressor core is blocked, improving the heat insulation effect and reliability, and making the vibration reduction effect during exhaust more significant. The exhaust hose has a simpler shape, a shorter exhaust path, and uses less material. Due to the inherent properties of the material, the exhaust hose has better heat insulation and greater damping, thus improving the vibration reduction effect. The exhaust hose can be thermoformed, making it less prone to deformation after forming and highly reliable. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] In the field of modern refrigeration equipment, the refrigerator compressor, as a core component, directly affects the overall operation and user experience of the refrigerator. Currently, metal exhaust pipes (6) are widely used in refrigerator compressors on the market. From a manufacturing perspective, metal exhaust pipes (6) do have certain advantages in shaping and welding processes. However, metal exhaust pipes (6) have limitations in heat transfer and vibration control. Due to the excellent thermal conductivity of metal materials, a large amount of heat generated by the compressor core during operation is rapidly transferred away through the metal exhaust pipe (6). This not only leads to an increase in the ambient temperature around the compressor, affecting the normal operation of other components, but may also cause energy loss and reduce the compressor's energy efficiency ratio. Metal exhaust pipes (6) have high rigidity and weak vibration buffering capacity. When the compressor is running, the vibrations generated by internal mechanical movement are directly transmitted through the metal exhaust pipe (6), easily causing resonance. As the compressor speed increases, this vibration problem becomes more severe. Currently, the maximum design speed of compressors generally does not exceed 4500 RPM. Within this speed range, existing cover plate assembly solutions using metal exhaust pipes (6) can maintain a relatively stable operating state. However, problems become increasingly apparent as the rotational speed continues to increase. Existing cover plate assembly solutions lead to a sharp increase in vibration and noise with further increases in rotational speed. Compressors using exhaust hose assemblies, on the other hand, demonstrate superior performance. Even when these compressors reach speeds of 6300 RPM, vibration and noise levels remain acceptable. Exhaust hose assemblies typically utilize materials with good flexibility and damping properties, such as specific rubbers or plastics. These materials effectively absorb and attenuate vibration energy, reducing vibration transmission. At high speeds, the exhaust hose 3 can buffer vibration through its own deformation, preventing resonance and effectively controlling the amplitude of vibration.

[0021] The compressor of this utility model mainly consists of key components such as a silencer chamber 2, an exhaust pipe 6, an exhaust hose assembly, and a frame. The silencer chamber 2 and the exhaust pipe 6 are respectively located on both sides of the frame. This layout fully considers space utilization and airflow direction, making the overall structure of the compressor more compact and rational. Between the silencer chamber 2 and the exhaust pipe 6, a crankcase 1 is installed. As an important component of the compressor, the crankcase 1 plays a crucial role in the entire system, working in conjunction with the silencer chamber 2 and the exhaust pipe 6 to jointly complete the various functions of the compressor.

[0022] like Figure 1 As shown, both the silencing chamber 2 and the exhaust pipe 6 have welded pipes 5 at one end, which are connected by an exhaust hose 3. The welded pipes 5 are made of metal, and the exhaust hose 3 and the welded pipes 5 are connected by clamps 4. This connection method creates a stable and efficient exhaust channel, ensuring smooth exhaust. The exhaust hose 3 is made of a high-pressure resistant, oil-incompatible plastic, and uses an embedded interference fit with the welded pipe 5. This connection method has many advantages. First, the embedded interference fit ensures a tight connection between the exhaust hose 3 and the welded pipe 5, greatly improving the reliability and sealing of the connection. During compressor operation, high-pressure gas flows in the exhaust channel, and the tight connection effectively prevents gas leakage, ensuring the normal operation of the compressor. Second, the plastic exhaust hose 3 has good flexibility and corrosion resistance, and can adapt to different working environments. It can work stably in high-temperature, humid, or chemically corrosive environments, extending the service life of the entire exhaust system. Its high-pressure resistance allows the exhaust hose 3 to withstand the high pressure generated by the compressor during operation without breaking or deforming due to excessive pressure; its oil incompatibility ensures that the hose will not undergo a chemical reaction when in contact with lubricating oil or other oily substances, thereby avoiding aging and damage to the hose and further improving the safety of the system.

[0023] like Figure 1As shown, the exhaust hose 3 is L-shaped, with a wall thickness ranging from 0.1-10mm and a length ranging from 80-300mm. Its cylindrical shape allows for flexible bending to be adapted to the dimensions and shape of the crankcase 1. The L-shaped design effectively utilizes space, making the compressor structure more compact and facilitating installation and maintenance. Simultaneously, this layout helps reduce resistance during the exhaust process, improving exhaust efficiency and reducing energy consumption. By rationally controlling the wall thickness and length, the weight of the exhaust hose 3 can be minimized while ensuring its strength and performance, thus reducing material costs. The cylindrical shape and adaptable bending design allow the exhaust hose 3 to better adapt to different installation environments, improving its versatility and flexibility. For example, in some small compressors where space is limited, the L-shaped exhaust hose 3 can cleverly bypass other components for compact installation; while in large compressors, the bending shape of the exhaust hose 3 can be customized to fit the specific shape of the crankcase 1, ensuring efficient operation of the exhaust system. By assembling the exhaust hose 3, heat from the compressor core is effectively blocked. During compressor operation, the compressor core generates a significant amount of heat. Direct transfer of this heat to other components could negatively impact their performance and lifespan. Due to the inherent properties of its material, the exhaust hose 3 provides excellent insulation, preventing heat transfer and improving the overall insulation performance of the compressor system. Furthermore, the exhaust hose 3 exhibits greater damping, resulting in more significant vibration reduction during exhaust. During exhaust, the impact of airflow causes pipe vibration, and the high damping characteristic of the exhaust hose 3 effectively absorbs and attenuates this vibration energy, reducing its impact on other compressor components, lowering noise levels, and improving the compressor's operational stability and reliability. The exhaust hose 3 also boasts a simpler shape compared to the traditional six-channel exhaust pipe structure. This design not only shortens the exhaust path, reducing flow resistance and improving exhaust efficiency, but also requires less material, lowering production costs. The exhaust hose 3 can be thermoformed, making it less prone to deformation after molding, further enhancing its reliability. During production, thermoforming allows the plastic material to fully fuse and solidify, forming a stable structure. This ensures that the exhaust hose 3 maintains its shape during long-term use, preventing deformation due to external forces or temperature changes, thus guaranteeing the normal operation of the exhaust system.

[0024] like Figure 2As shown, the clamp 4 is a crucial component connecting the exhaust hose 3 and the welded pipe 5. Its ingenious design plays a key role in the stability of the entire exhaust system. The clamp 4 is a cylindrical shell open at both ends, with several clamping blocks 4.4 at one end, symmetrically arranged along the central axis of the clamp 4. The clamping blocks 4.4 are bent inward into an L-shape. One end of the clamping block 4.4 is in the same curved surface as the wall of the clamp 4, while the other end is perpendicular to the wall of the clamp 4. The side of the end perpendicular to the wall of the clamp 4, facing inward, is the clamping surface 4.5. This structural design allows the clamping blocks 4.4 to apply pressure evenly, ensuring the stable fixation of the exhaust hose 3 on the welded pipe 5. The symmetrical arrangement of the clamping blocks 4.4 avoids hose damage or loosening due to excessive local pressure, thereby improving the stability and reliability of the connection.

[0025] The clamping surface 4.5 is an arc surface, perpendicular to the central axis of the clamp 4, and several clamping surfaces 4.5 are arranged opposite each other along the central axis of the clamp 4. The arc surface of the clamping surface 4.5 can better fit the outer wall of the exhaust hose 3, increasing the contact area and improving the clamping effect. When the clamp 4 tightens the exhaust hose 3, the arc surface of the clamping surface 4.5 is in close contact with the outer wall of the exhaust hose 3, so that the pressure is evenly distributed on the hose surface, avoiding damage to the hose caused by local stress concentration. The oppositely arranged clamping surfaces 4.5 can form a stable clamping structure, further enhancing the fixing effect of the exhaust hose 3 and preventing it from shifting during operation. When the compressor is running, the exhaust hose 3 will be subjected to the impact and vibration of airflow. The stable clamping structure can ensure that the hose always stays in the correct position, ensuring the normal operation of the exhaust system.

[0026] like Figure 2As shown, the clamp 4 has an opening 4.3 along the busbar. A first bend 4.1 is provided on one side of the opening 4.3, and a clearance hole 4.6 is provided on the first bend 4.1. A second bend 4.2 passes through the clearance hole 4.6, and the first bend 4.1 and the second bend 4.2 are positioned in opposite directions. In actual operation, the operator simply needs to hold the first bend 4.1 and the second bend 4.2 with both hands and gently pry them closer together. As this prying action is performed, the clamp 4 will slowly open along the opening 4.3. This opening process is very smooth. Once the clamp 4 has opened to the appropriate degree, the operator can smoothly place the exhaust hose 3 into the space reserved inside the clamp 4. During placement, special attention should be paid to accurately aligning the clamping surface 4.5 on the clamp 4 with the outer wall of the exhaust hose 3. After completing the placement of the exhaust hose 3 and aligning the clamping surfaces, the operator simply needs to slowly release the previously pryed first bend 4.1 and second bend 4.2. As the two bends spring back, the clamp 4 quickly returns to its initial closed state, firmly securing both ends of the exhaust hose 3 to the outer walls of the two welded pipes 6. This design allows the clamp 4 to be quickly opened and closed with a simple prying motion, facilitating the installation and removal of the exhaust hose 3. Simultaneously, the oppositely oriented bends provide better elastic support, ensuring that the clamp 4 tightly holds the exhaust hose 3 after closing. In practice, operators can easily open and close the clamp 4, greatly improving installation and maintenance efficiency.

[0027] like Figure 2 As shown, the second bend 4.2 is provided along the wall surface of the clamp 4, and the arc angle is the same as the curvature of the cylindrical wall surface of the clamp 4. This design allows the second bend 4.2 to fit tightly against the wall surface of the clamp 4, improving the overall structural strength and stability of the clamp 4. During the opening and closing process of the clamp 4, the same arc angle ensures that the clamp 4 maintains uniform elastic deformation, avoids local stress concentration, and extends the service life of the clamp 4. In addition, the width of the second bend 4.2 is smaller than the width of the clearance hole 4.6. This design ensures the flexibility and operability of the clamp 4 during installation and disassembly, making it easy for operators to perform operations, even in confined spaces, to smoothly complete the installation and disassembly of the clamp 4.

[0028] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
