Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to an internal exhaust device for a compressor using a plastic hose. Background Technology

[0002] When the refrigerator compressor is working, it is driven by a motor, which drives the piston to bring in gas through the suction pipe. The gas then passes through the valve assembly and finally enters the cylinder. The motor then compresses the gas in the cylinder and sends it through the valve assembly and the internal exhaust pipe before it leaves the compressor through the exhaust port. During this process, the exhaust pipe connects the compressor core and the housing. In addition to expelling the compressed high-temperature and high-pressure gas from the compressor, it also transfers heat to the compressor cavity and transmits the compressor's vibration.

[0003] For example, publication number "CN201531428U" discloses "a compressor exhaust pipe assembly," which includes a metal exhaust pipe. The characteristic feature is that an exhaust connecting ring is welded to one end of the exhaust pipe. This metal exhaust connecting ring has a cylindrical structure and connects to the metal exhaust pipe through a through hole on its side wall. However, in practical applications, the diameter of the metal inner exhaust pipe is relatively large, and the bending radius is also relatively large, making it unsuitable for use in smaller-sized, smaller-displacement refrigerator compressors. Regarding replacement and disassembly, the entire inner exhaust pipe needs to be welded off, resulting in high replacement costs and inconvenience. Summary of the Invention

[0004] In view of the problem of high production and maintenance costs in the existing technology mentioned in the background, this utility model provides an internal exhaust device for a plastic hose of a compressor, which can improve the vibration reduction effect by changing the material of the pipe, while achieving a more flexible adjustment effect, lower production cost, and improving maintenance efficiency and reducing maintenance cost in subsequent maintenance processes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] An internal exhaust device for a compressor using a plastic hose includes a plastic hose with an exhaust pipe connected to its end. The exhaust pipe has a tower-shaped connector with a tower-shaped protrusion. A fixing groove is located on the side of the tower-shaped protrusion away from the plastic hose. A clamp is connected to the plastic hose, and a fixing hook is located on the side of the clamp near the exhaust pipe. A connection hole is located within the clamp, connecting to the tower-shaped protrusion. The fixing hook engages with the fixing groove. In this application, by using a plastic hose with damping properties, connecting the plastic hose to the tower-shaped connector, and fixing the connection point within the clamp, improvements are made in installation, disassembly, and connection stability. Furthermore, the use of plastic, whose damping properties are often greater than metal, gives it an advantage in reducing vibration amplitude and significantly improving vibration reduction, thus ensuring stability during use. Additionally, the tower-shaped protrusion connection allows the tower-shaped connector to connect to the plastic hose within the connection hole, reducing the probability of loosening and improving connection stability. Furthermore, a fixing groove is provided on the tower-shaped connector. The connection between the fixing groove and the fixing hook on the clamp further ensures the tightness of the connection between the plastic hose, exhaust pipe, and clamp. While ensuring stability of the plastic hose connection via the tower-shaped connector, the connection with the clamp is further enhanced, resulting in a mutual restraining effect among the three components. Due to the crimp-type clamp design, installation and disassembly are more efficient. During subsequent maintenance and replacement, individual plastic hoses or exhaust pipes can be replaced individually, resulting in high replacement efficiency and low maintenance costs.

[0007] Preferably, the tower-shaped connector is provided with a plurality of tower-shaped protrusions, which are arranged along the axial direction of the exhaust pipe. The presence of multiple tower-shaped protrusions on the tower-shaped connector ensures a tight connection with the plastic hose and prevents misalignment of the connector during connection, thus guaranteeing alignment.

[0008] Preferably, the fixing groove is an annular groove centered on the axis of the exhaust pipe. By designing the fixing groove as an annular structure, the fixing hook can be engaged with the fixing groove at any angle during use, ensuring flexibility during assembly and adapting to various rotation angles of the exhaust pipe.

[0009] Preferably, the clamp has several fixing hooks arranged symmetrically. This symmetrical arrangement of multiple fixing hooks ensures uniform and reliable connection between the fixing hooks and the fixing grooves, while also facilitating installation and disassembly by the user.

[0010] Preferably, the clamp is a cylindrical structure, which is formed by connecting the ends of a sheet-like structure. The cylindrical structure ensures a tight connection with the plastic hose and exhaust pipe. Furthermore, the cylindrical structure formed by connecting the ends of the sheet-like structure improves production efficiency and saves processing costs. Because it is a cylindrical structure formed by sheet-like structures, the overall structural strength of the clamp is guaranteed during use, making it less prone to damage. Moreover, being a one-piece molded sheet-like structure, when the clamp is made of metal or other materials, the sheet-like structure forming a cylindrical shape gives the clamp a certain degree of elasticity, thus ensuring a tight clamping grip on the exhaust pipe and plastic hose during use.

[0011] Preferably, the clamp includes a fitting piece and a hollow piece. When the clamp is in a sheet-like structure, the fitting piece and the hollow piece are located on opposite sides of the sheet-like structure. The hollow piece has a fitting groove that allows the fitting piece to pass through. The clamp includes a fitting piece and a hollow piece, which are respectively located at both ends of the clamp (sheet-like structure). Subsequent closing of the sheet-like structure forms a cylindrical structure, allowing the hollow piece and the fitting piece at both ends to align. The hollow piece has a fitting groove, creating a hollow structure. The fitting groove allows the fitting piece to pass through, resulting in an interlocking structure between the hollow piece and the fitting piece. This facilitates tightening and loosening by the user, improving operational efficiency.

[0012] Preferably, after the clamp is formed into a cylindrical structure, the fitting piece and the hollow piece on the side away from the clamp axis tilt upwards to form a handle. The fitting piece and the hollow piece form a handle structure, which makes operation more convenient and efficient during use, reduces the operating space, and avoids interference from surrounding components during maintenance.

[0013] Preferably, the clamp has several fixing hooks, each symmetrically arranged along the junction of the fitting piece and the hollow piece. This symmetrical arrangement of the fixing hooks at the junction of the fitting piece and the hollow piece ensures that the fixing hooks move synchronously when the fitting piece and the hollow piece move, thus facilitating opening and closing of the fixing hooks and making disassembly and installation convenient.

[0014] Preferably, the clamp is provided with an observation window, which is hollowed out. Because the observation window is hollowed out, the connection between the exhaust pipe and the plastic hose inside the clamp can be observed during use, thereby determining whether the connection position is appropriate and improving connection accuracy.

[0015] Preferably, the exhaust pipe is connected to a degassing manifold on the side away from the plastic hose, the degassing manifold is connected to a metal inner exhaust pipe on the side away from the exhaust pipe, and the metal inner exhaust pipe is connected to a cover plate on the side away from the degassing manifold.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) The vibration reduction effect can be improved by changing the material of the pipe, while the adjustment effect can be more flexible, the production cost is lower, and the maintenance efficiency can be improved and the maintenance cost can be reduced in the subsequent maintenance process.

[0018] (2) It can ensure the stability of the connection, facilitate subsequent disassembly and replacement, improve construction efficiency, and eliminate the need to replace the entire device. It can be partially replaced, save operating space, and avoid interference from other parts during installation and disassembly. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1:

[0031] When the refrigerator compressor is working, it is driven by a motor, which drives the piston to bring in gas through the suction pipe. The gas then passes through the valve assembly and finally enters the cylinder. The motor then compresses the gas in the cylinder and sends it through the valve assembly and the internal exhaust pipe before it leaves the compressor through the exhaust port. During this process, the exhaust pipe connects the compressor core and the housing. In addition to expelling the compressed high-temperature and high-pressure gas from the compressor, it also transfers heat to the compressor cavity and transmits the compressor's vibration.

[0032] Currently, refrigerator compressors use metal exhaust pipes, which offer advantages in shaping and welding processes, but have limitations in heat transfer and vibration control. Using plastic exhaust pipes would significantly improve the compressor's heat insulation. From a damping perspective, plastic generally has higher damping than metal, making it more effective at reducing vibration amplitude and providing more significant vibration reduction. Furthermore, considering the properties, cost, and processing technology of metal, metal exhaust pipes have larger diameters and larger bending radii, making them unsuitable for smaller-sized, lower-displacement refrigerator compressors. In terms of replacement, metal exhaust pipes require the entire pipe to be welded off, resulting in higher costs and greater inconvenience.

[0033] To address the aforementioned problems, this embodiment employs the following solution: This embodiment provides an internal exhaust device for a compressor using a plastic hose 1. This device can improve vibration damping by changing the material of the pipe, while also achieving more flexible adjustment, lower production costs, and improved maintenance efficiency and reduced maintenance costs during subsequent maintenance processes.

[0034] like Figure 1As shown, a compressor plastic hose exhaust device includes a plastic hose 1, an exhaust pipe 2 connected to the end of the plastic hose 1, a tower-shaped connector 21 provided on the exhaust pipe 2, a tower-shaped protrusion 22 provided on the tower-shaped connector 21, a fixing groove 23 provided on the side of the tower-shaped protrusion 22 away from the plastic hose 1, a clamp 3 connected to the plastic hose 1, a fixing hook 31 provided on the side of the clamp 3 near the exhaust pipe 2, a connecting hole 32 provided in the clamp 3, the connecting hole 32 connecting with the tower-shaped protrusion 22, and the fixing hook 31 engaging with the fixing groove 23. In this application, by making the plastic hose 1 a damping-type plastic material, connecting the plastic hose 1 to the tower-shaped connector 21, and fixing the connection point of the two in the clamp 3, the installation, disassembly, and connection stability are improved. Furthermore, because plastic is used, and plastic's damping is often greater than that of metal, plastic has a greater advantage in improving vibration amplitude and a more significant vibration reduction effect, thus ensuring stability during use. Additionally, the use of the tower-shaped protrusion 22 in this application allows the tower-shaped connector 21 to connect to the plastic hose 1 within the connection hole 32, reducing the probability of loosening and improving connection stability. Furthermore, a fixing groove 23 is provided on the tower-shaped connector 21. The connection between the fixing groove 23 and the fixing hook 31 on the clamp 3 further ensures the tightness of the connection between the plastic hose 1, the exhaust pipe 2, and the clamp 3. While ensuring stability by connecting the plastic hose 1 to the tower-shaped connector 21, the connection with the clamp 3 is further enhanced, resulting in a mutual limiting effect among the three components. Because of the crimping design of the clamp 3, the installation and disassembly are more efficient. In subsequent maintenance and replacement processes, a single plastic hose 1 or exhaust pipe 2 can be replaced, resulting in high replacement efficiency and low maintenance costs.

[0035] like Figure 2 As shown, the tower-shaped connector 21 is provided with a number of tower-shaped protrusions 22, and each tower-shaped protrusion 22 is arranged along the axial direction of the exhaust pipe 2. The multiple tower-shaped protrusions 22 on the tower-shaped connector 21 can ensure the tightness of the connection with the plastic hose 1, and the multiple tower-shaped protrusions 22 can prevent the tower-shaped connector 21 from shifting during the connection process, ensuring the alignment of the connection.

[0036] like Figure 2 As shown, the fixing groove 23 is an annular groove centered on the axis of the exhaust pipe 2. By setting the fixing groove 23 as an annular groove structure, the fixing hook 31 can be connected and engaged with the fixing groove 23 at any angle during use, ensuring flexibility in the assembly process and adapting to various rotation angles of the exhaust pipe 2.

[0037] like Figure 3 , 4As shown, the clamp 3 has several fixing hooks 31 arranged symmetrically. By symmetrically arranging and having multiple fixing hooks 31 on the clamp 3, the uniformity and reliability of the connection between the fixing hooks 31 and the fixing groove 23 can be ensured, while also facilitating installation and disassembly by the user.

[0038] like Figure 3 As shown, clamp 3 has a cylindrical structure, which is formed by connecting the ends of a sheet-like structure. The cylindrical structure of clamp 3 ensures a tight connection with the plastic hose 1 and the exhaust pipe 2. Furthermore, the cylindrical structure formed by connecting the ends of the sheet-like structure improves production efficiency and saves processing costs. Because it is a cylindrical structure formed by sheet-like structures, the overall structural strength of clamp 3 is guaranteed during use, making it less prone to damage. Moreover, being a one-piece molded sheet-like structure, when clamp 3 is made of metal or other materials, the sheet-like structure forming a cylindrical shape gives clamp 3 a certain degree of elasticity, thus ensuring the clamp 3 can securely hold the exhaust pipe 2 and the plastic hose 1 during use.

[0039] like Figure 3 As shown, the clamp 3 includes a fitting piece 33 and a hollow piece 34. When the clamp 3 is in a sheet-like structure, the fitting piece 33 and the hollow piece 34 are located on both sides of the sheet-like structure. The hollow piece 34 has a fitting groove 341 that allows the fitting piece 33 to pass through. The clamp 3 includes a fitting piece 33 and a hollow piece 34, which are respectively located at both ends (sheet-like structure) of the clamp 3. Through subsequent enclosure, the sheet-like structure is formed into a cylindrical structure, allowing the hollow piece 34 and the fitting piece 33 at both ends to align. The hollow piece 34 has a fitting groove 341, which creates a hollow structure in the hollow piece 34. The fitting groove 341 allows the fitting piece 33 to pass through, thus forming an interlaced structure between the hollow piece 34 and the fitting piece 33. This facilitates tightening and loosening by the user, improving operational efficiency.

[0040] like Figure 3 As shown, after the clamp 3 is formed into a cylindrical structure, the fitting piece 33 and the hollow piece 34 on the side away from the axis of the clamp 3 tilt up and form a handle 35. The fitting piece 33 and the hollow piece 34 form the handle 35 structure, which makes it easier to operate during use, improves operating efficiency, reduces operating space, and avoids interference from surrounding parts during maintenance.

[0041] like Figure 3As shown, the clamp 3 has several fixing hooks 31, which are symmetrically arranged along the junction of the fitting piece 33 and the hollow piece 34. The symmetrical arrangement of the fixing hooks 31 at the junction of the fitting piece 33 and the hollow piece 34 ensures that the fixing hooks 31 move synchronously when the fitting piece 33 and the hollow piece 34 move, thus enabling the fixing hooks 31 to open and close, facilitating disassembly and installation.

[0042] like Figure 4 As shown, the clamp 3 is provided with an observation window 36, which is hollowed out. Because the observation window 36 is hollowed out, the connection between the exhaust pipe 2 and the plastic hose 1 inside the clamp 3 can be observed during use, thereby determining whether the connection position is appropriate and improving connection accuracy.

[0043] like Figure 1 As shown, the exhaust pipe 2 is connected to a degassing manifold 4 on the side away from the plastic hose 1, the degassing manifold 4 is connected to a metal inner exhaust pipe 5 on the side away from the exhaust pipe 2, and the metal inner exhaust pipe 5 is connected to a cover plate 6 on the side away from the degassing manifold 4.

[0044] The assembly and operation process of the exhaust device inside the plastic hose of the compressor in this embodiment is as follows: In this embodiment, the plastic hose 1 is made of plastic material. After using the exhaust pipe 2 made of plastic material, the heat insulation capacity of the compressor will be greatly improved. From the perspective of damping characteristics, the damping of plastic is often greater than that of metal, which makes plastic material more advantageous in improving vibration amplitude and the vibration reduction effect more significant. In this embodiment, the connection method between the plastic hose 1 and the exhaust pipe 2 is a crimp type, which is connected and fixed by the clamp 3 at the connection between the plastic hose 1 and the exhaust pipe 2. The clamp 3 is a cylindrical structure. Before the clamp 3 forms a cylindrical structure, the initial material shape is sheet-like. The two ends of the sheet-like material are provided with fitting pieces 33 and hollow pieces 34. The hollow piece 34 is provided with a fitting groove 341. The size of the fitting groove 341 is larger than the size of the fitting piece 33. Through the above setting method, when the sheet-like structure is wound, the ends of the sheet-like structure will be connected, so that the hollow piece 34 and the fitting piece 33 can be connected.

[0045] The hollow piece 34 has a fitting groove 341, and the size of the fitting groove 341 is larger than the size of the fitting piece 33. This allows the fitting piece 33 to be inserted into the fitting groove 341. After the fitting groove 341 and the fitting piece 33 are aligned, the ends of the hollow piece 34 and the fitting piece 33 are tilted upwards, forming an "X" shaped interlaced structure with the entire clamp 3. This makes the ends of the fitting piece 33 and the hollow piece 34 form a handle 35. During use, the two ends of the handle 35 can be pushed towards the middle using pliers or fingers. Since the entire clamp 3 is a one-piece structure, the diameter of the connecting hole 32 in the clamp 3 can be increased. This allows the plastic hose 1 and the exhaust pipe 2 to be removed from the clamp 3, improving subsequent maintenance efficiency. During subsequent installation, the diameter of the connecting hole 32 can still be reduced by pulling the handle 35 to both sides, thereby clamping and securing the plastic hose 1 and the exhaust pipe 2 connected to the inside of the clamp 3. In this embodiment, three tower-shaped connectors 21 are provided on the exhaust pipe 2. The tower-shaped connectors 21 have a trapezoidal truncated cone structure, with the smaller end near the plastic hose 1, which facilitates connection with the plastic hose 1 and reduces the probability of the tower-shaped connectors 21 detaching from the plastic hose 1. A fixing groove 23 is provided at the end of the tower-shaped connectors 21. The fixing groove 23 has an annular structure and can be adapted to the fixing hooks 31 on the clamp 3. In this embodiment, there are two fixing hooks 31, which are symmetrically arranged, and the line of symmetry coincides with the line of intersection of the clamp 35. This allows the fixing hooks 31 on both sides to be pulled apart when the clamp 35 is pressed, thereby separating the fixing hooks 31 from the fixing groove 23 and facilitating the detachment of the tower-shaped connectors 21. Since the fixing groove 23 has an annular structure, when the fixing hooks 31 are engaged with the fixing groove 23, the connection between the exhaust pipe 2 and the plastic hose 1 is kept tight, preventing detachment. In this embodiment, a degassing manifold 4 is also connected. The degassing manifold 4 is connected to the end of the exhaust pipe 2 away from the plastic hose 1, and a metal inner exhaust pipe 5 is connected to the other end of the degassing manifold 4. A cover plate 6 is connected to the end of the metal inner exhaust pipe 5. The cover plate 6 has a cylindrical structure and is provided with assembly holes to ensure the stability of the connection.

[0046] The structural design described above in this embodiment achieves the following beneficial effects: it can improve the vibration reduction effect by changing the material of the pipe, while also achieving a more flexible adjustment effect, lower production costs, and improving maintenance efficiency and reducing maintenance costs in subsequent maintenance processes; it can ensure the stability of the connection, facilitate subsequent disassembly and replacement, improve construction efficiency, and eliminate the need to replace the entire device, allowing for partial replacement, while also saving operating space and avoiding interference from other components during installation and disassembly.
