Abstract
Description
Technical Field
[0001] This application relates to the field of dehumidifier technology, and in particular to a dehumidifier return air pipe and a dehumidifier. Background Technology
[0002] To achieve its humidity and temperature control functions, a dehumidifier first draws in humid air and transfers it to the surface of the evaporator. The refrigerant inside the evaporator condenses the moisture in the air, reducing humidity before the air is blown out through the outlet, thus lowering indoor humidity and temperature. Simultaneously, the refrigerant in the evaporator, after absorbing heat, needs to be transferred back to the compressor for compression to maintain the overall system's circulation efficiency.
[0003] In existing technologies, refrigerant in the evaporator is typically transported to the compressor for compression via a return pipe. However, due to structural limitations in dehumidifiers, the evaporator and compressor are often not on the same horizontal plane. Transporting refrigerant via a conventional return pipe makes it difficult to control the refrigerant flow rate, resulting in significant vibration and noise, thus affecting the user experience.
[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0012] In one embodiment, the other end of the second return air section is arranged parallel to the other end of the first return air section, and the first included angle and the second included angle are equal.
[0013] In one embodiment, the center angle of the first bend is 160°-200°, and the radius of curvature of the first bend is 2.0-3.0 times the outer diameter of the dehumidifier return pipe.
[0014] In one embodiment, the center angle of the first bend is 180°, and the radius of curvature of the first bend is 2.5 times the outer diameter of the dehumidifier return pipe.
[0015] In one embodiment, a second bend is provided between one end of the first return air section and the other end of the first return air section, the second bend forming the lowest point of the dehumidifier return air pipe.

[0017] In one embodiment, one end of the first return gas section forms a plurality of smoothly connected conveying pipes from the evaporator to the second bend, and the inclination angles between the conveying pipes are different, so as to control the speed of the refrigerant when it is delivered to the second bend and reduce the vibration at the second bend during the refrigerant delivery process.
[0018] In one embodiment, the dehumidifier return pipe further includes a vibration damping sleeve, which wraps around the first return section, the second return section, and the vibration damping section to reduce the vibration of the dehumidifier return pipe when the refrigerant is transported.

[0034] In existing technologies, dehumidifiers typically use a compressor to drive refrigerant circulation. The refrigerant is delivered to the evaporator, where it initially contacts the incoming humid air, condensing the moisture in the air before being expelled, thus achieving dehumidification and temperature control of the indoor air. After absorbing heat in the evaporator, the refrigerant needs to be transported from the evaporator to the compressor via a return pipe for recompression and condensation to ensure efficient heat absorption in subsequent cycles. However, due to the size limitations of the dehumidifier itself, the evaporator and compressor are positioned on different horizontal planes, creating a height difference between them. Therefore, the refrigerant delivery speed through the return pipe cannot be effectively controlled, often resulting in vibration and noise during operation, affecting the user experience.
[0035] To address the issues of vibration and noise generated during operation by existing dehumidifier return pipes, this application provides a dehumidifier return pipe and a dehumidifier. The dehumidifier return pipe connects the evaporator and compressor within the dehumidifier, and delivers the refrigerant from the evaporator to the compressor for compression. Through the structural design of the dehumidifier return pipe, this application effectively controls the refrigerant delivery speed, reduces vibration and noise during operation, and provides a better user experience.
[0036] Specifically, such as Figure 1 and Figure 2 As shown, the dehumidifier return pipe includes a first return section 100, a second return section 200, and a vibration damping section 300. Wherein, one end of the first return gas section 100 is connected to the evaporator 400, and the other end of the first return gas section 100 extends toward the compressor 500; one end of the second return gas section 200 is connected to the compressor 500, and the other end of the second return gas section 200 extends toward the evaporator 400; the vibration damping section 300 is integrally formed with and connected to the other end of the first return gas section 100 and the other end of the second return gas section 200, to form a conveying path from the evaporator 400 to the compressor 500, wherein the vibration damping section 300 is provided with a first bend 310, the first bend 310 and the other end of the first return gas section 100 form a first included angle 311, the first bend 310 and the other end of the second return gas section 200 form a second included angle 312, and the first included angle 311 and the second included angle 312 are 90°-110°. By setting a first bend 310 at an angle to the first return gas section 100 and the second return gas section 200, the refrigerant speed can be well controlled when the refrigerant is delivered from the evaporator 400 to the compressor 500 through the first return gas section 100, the vibration damping section 300 and the second return gas section 200 in sequence. This reduces the vibration of the dehumidifier's return gas pipe during operation and lowers the noise caused by the vibration, bringing users a better user experience.
[0037] In one implementation, such as Figure 3 and Figure 5As shown, the vibration damping section 300 is connected to the first return air section 100 and the second return air section 200 respectively via an arc-shaped pipe 320 to ensure a smooth connection of the dehumidifier's return air pipe. The vibration damping section 300 extends and rotates towards the compressor 500 to form the first bend 310. The arc-shaped pipe 320 ensures a smooth and continuous structure of the dehumidifier's return air pipe, allowing the refrigerant to flow smoothly along the inner wall during its movement within the pipe, avoiding turbulence at the turning points that could cause vibration and noise. Furthermore, the first bend 310 forms an angle with the first return air section 100 and the second return air section 200 before turning towards the compressor 500, thereby extending the refrigerant's transport path within the dehumidifier's return air pipe. This allows for better control of the refrigerant's transport speed and reduces vibration and noise during refrigerant transport.
[0038] In one implementation, such as Figure 3 and Figure 5 As shown, the other end of the second return air section 200 is arranged parallel to the other end of the first return air section 100, and the first included angle 311 and the second included angle 312 are equal. In this embodiment, the vibration damping section 300 and the first bend 310 are arranged symmetrically, and the other end of the parallel second return air section 200 is connected to the other end of the first return air section 100, thereby ensuring the smooth flow of refrigerant in the dehumidifier's return air pipe and reducing vibration and noise caused by refrigerant flow during operation.
[0039] In one embodiment, the central angle of the first bend 310 is 160°-200°, and the radius of curvature of the first bend 310 is 2.0-3.0 times the outer diameter of the dehumidifier's return air pipe. By adjusting the specific structure of the first bend 310, the flow speed of the refrigerant within the dehumidifier's return air pipe is changed, thereby reducing vibration and noise caused by refrigerant flow during operation.
[0040] In one implementation, such as Figure 5 As shown, the central angle of the first bend 310 is 180°, and the radius of curvature of the first bend is 2.5 times the outer diameter of the dehumidifier return pipe. In this embodiment, by setting the specific structure of the first bend 310, it is ensured that the refrigerant will not resonate when flowing in the dehumidifier return pipe, thereby maximizing the reduction of vibration of the dehumidifier return pipe and reducing noise during operation.
[0041] In one implementation, such as Figure 3 and Figure 4As shown, a second bend 130 is provided between one end and the other end of the first return air section 100, forming the lowest point of the dehumidifier's return air pipe. By setting the second bend 130, the path of the refrigerant flowing in the dehumidifier's return air pipe is extended, thereby better regulating the flow speed of the refrigerant in the dehumidifier's return air pipe and improving the vibration and noise generated when the refrigerant flows in the dehumidifier's return air pipe. Furthermore, by adjusting the center angle, radius of curvature, and tilt angle of the second bend 130, the vibration caused by the refrigerant flowing in the dehumidifier's return air pipe is reduced, further reducing the noise generated during operation and providing users with a better user experience.
[0042] In one implementation, such as Figure 1 and Figure 2 As shown, the dehumidifier return pipe also includes a vibration damping block 140. The vibration damping block 140 is held on the first return section 100 at the position corresponding to the second bend 130 to reduce vibration at the second bend 130 during refrigerant delivery. Specifically, the vibration damping block 140 is a ring-shaped counterweight. After being fitted and fixed on the second bend 130, it can reduce the vibration caused by the refrigerant flowing through the second bend 130, thereby further reducing the noise generated by the refrigerant flowing in the dehumidifier return pipe during operation.
[0043] In one implementation, such as Figure 1 and Figure 6 As shown, one end of the first return gas section 100 forms several smoothly connected conveying pipes 150 from the evaporator 400 to the second bend 130, and the inclination angles of each conveying pipe 150 are different to control the speed of the refrigerant when it is delivered to the second bend 130 and reduce the vibration at the second bend 130 during the refrigerant delivery process. Specifically, the inclination angle of the conveying pipe 150 gradually decreases as it extends from one end of the first return gas section 100 toward the second bend 130, so as to gradually slow down the flow speed of the refrigerant in the first return gas section 100, thereby avoiding turbulence and strong vibration caused by the refrigerant flowing through the second bend 130, thus reducing noise during operation and providing a better user experience.
[0044] In one implementation, such as Figure 7 and Figure 8As shown, the dehumidifier return air pipe also includes a vibration damping sleeve 600, which wraps around the first return air section 100, the second return air section 200, and the vibration damping section 300 to reduce the vibration of the dehumidifier return air pipe during refrigerant delivery. Optionally, the vibration damping sleeve 600 is a vibration damping sponge that wraps around the dehumidifier return air pipe to absorb the vibration caused by the refrigerant flowing within the dehumidifier return air pipe, reducing the noise of the dehumidifier return air pipe during operation and improving the user experience.
[0045] This application also discloses a dehumidifier, such as Figure 1 and Figure 2 As shown, the dehumidifier includes a dehumidifier return pipe as described above, connecting the evaporator 400 and compressor 500 within the dehumidifier, and supplying refrigerant from the evaporator 400 to the compressor 500. By structurally designing the dehumidifier return pipe, vibrations generated by the refrigerant flowing within it are reduced, and noise is lowered, resulting in quieter operation and a better user experience.
[0046] The following describes the specific structure of the dehumidifier return air duct and the dehumidifier in this application with reference to specific embodiments.
[0047] like Figure 1 and Figure 2 As shown, in one embodiment, the dehumidifier of this application includes a compressor 500 fixed on an internal base and an evaporator 400 disposed above the compressor 500. Refrigerant is compressed by the compressor 500 and then delivered to the evaporator 400. The refrigerant flows through the evaporator 400 and exchanges heat with the air drawn into the dehumidifier before being transported back to the compressor 500 through the dehumidifier return air duct for further compression, completing one cycle. In this embodiment, by specifically configuring the structure of the dehumidifier return air duct, the speed of the refrigerant as it passes through the duct is adjusted, thereby reducing vibration and noise in the dehumidifier return air duct, making the dehumidifier quieter during operation and optimizing the user experience.
[0048] In this embodiment, as Figure 1 and Figure 3 As shown, the dehumidifier return air duct includes a first return air section 100, a vibration damping section 300, and a second return air section 200 connected in sequence. The first return air section 100, the vibration damping section 300, and the second return air section 200 are integrally formed to create a smooth and continuous dehumidifier return air duct structure, thereby ensuring the smooth flow of refrigerant within the dehumidifier return air duct, reducing the vibration of the dehumidifier return air duct during refrigerant flow, thus reducing noise and ensuring a better user experience.
[0049] Specifically, such as Figure 1As shown, one end of the first return gas section 100 is connected to the evaporator 400, and the other end of the first return gas section 100 is connected to the vibration damping section 300. In this embodiment, the end of the first return gas section 100 connected to the evaporator 400 is the first end 110 of the first return gas section, and the other end of the first return gas section 100 connected to the vibration damping section 300 is the second end 120 of the first return gas section. The first end 110 of the first return gas section is initially set horizontally to connect to the refrigerant pipe outlet of the evaporator 400, and then extends towards the compressor 500. Specifically, the first end 110 of the first return gas section first changes from a horizontal direction to a vertical direction and connects to the second bend 130 through several smoothly connected conveying pipes 150, wherein the inclination angle of the conveying pipes 150 gradually changes, gradually changing the flow direction of the refrigerant in the first return gas section 100 from a horizontal direction to a vertical direction, thereby avoiding excessively fast flow velocity of the refrigerant in the first return gas section 100 and reducing vibration and noise.
[0050] In this embodiment, the delivery pipes 150 are integrally connected to each other via an arc-shaped structure to ensure that the refrigerant can flow continuously and smoothly in the dehumidifier return air duct, thereby reducing vibration and noise of the dehumidifier return air duct during operation. Furthermore, the different delivery pipes 150 are not coplanar, and each delivery pipe 150 has a different angle with the vertical direction to adjust the refrigerant flow speed as needed.
[0051] Furthermore, in the first return gas section 100, the first end 110 of the first return gas section is connected to the second bend 130 through a plurality of the aforementioned conveying pipes 150, and is connected to the other end of the first return gas section 100 through the second bend 130. In this embodiment, the other end of the first return gas section 100 is the second end 120 of the first return gas section. Figure 3 As shown, the first return gas section 100 is connected to the first end 110 of the first return gas section and the second bend 130 through a plurality of the aforementioned delivery pipes 150, so as to control the speed at which the refrigerant flows into the second bend 130.
[0052] Specifically, in this embodiment, the second bend 130 is a U-shaped tube structure with a central angle of 180°. Both ends of the U-shaped tube are connected to a delivery pipe 150 and the second end 120 of the first return air section, respectively, so that the refrigerant flows vertically upwards after passing through 180° into the vibration damping section 300. Specifically, the second bend 130 is located in a vertical plane, and the bend of the U-shaped tube of the second bend 130 constitutes the lowest point of the dehumidifier's return air pipe, ensuring a smooth and stable flow of the refrigerant. Furthermore, a vibration damping block 140 is fitted onto the second bend 130 to prevent resonance in the dehumidifier's return air pipe when the refrigerant flows through, and to further reduce vibration and noise. Specifically, the vibration damping block 140 is a ring-shaped counterweight, surrounding and fixed to the second bend 130, thereby further reducing vibration and noise.
[0053] Furthermore, such as Figure 1 and Figure 2 As shown, the second end 120 of the first return air section extends vertically upwards beyond the height of the compressor 500, and then connects to the vibration damping section 300 via a first arc-shaped pipe 321. The vibration damping section 300 extends towards the compressor 500, thus positioning itself above the compressor 500 and between the compressor 500 and the evaporator 400. By precisely positioning the vibration damping section 300, the flow velocity of the refrigerant within it can be effectively reduced, thereby further reducing the vibration of the dehumidifier's return air pipe and lowering noise.
[0054] Furthermore, the central angle of the first arc-shaped pipe 321 corresponds to the first included angle 311 between the first return air section 100 and the vibration damping section 300, and the first included angle 311 is set within the range of 90°-110°. In this embodiment, as... Figure 4 As shown, the first included angle 311 is 100°. Ensuring that the first included angle 311 between the first return gas section 100 and the vibration damping section 300 is between 90° and 110° effectively controls the speed at which the refrigerant enters the vibration damping section 300 from the first return gas section 100, thereby reducing vibration and noise.
[0055] Furthermore, such as Figure 1 and Figure 5As shown, the vibration damping section 300 forms a first bend 310 above the compressor. One end of the first bend 310 is connected to the first return air section 100 through the first arc-shaped pipe 321, thereby ensuring the continuous and stable flow of refrigerant in the dehumidifier's return air pipe. After the refrigerant flows from the first return air section 100 into the vibration damping section 300, it will flow around the compressor 500. The refrigerant will flow in a plane with an angle of 90° to 110° with the vertical direction before entering the compressor through the second return air section 200. This can effectively reduce the vibration of the dehumidifier's return air pipe, thereby reducing noise and providing users with a better user experience.
[0056] Specifically, the first bend 310 is a U-shaped tube structure, wherein the bend of the first bend 310 is an arc-shaped structure with a central angle of 160°-200°. The radius of curvature of the first bend 310 is 2.0-3.0 times the outer diameter of the dehumidifier return pipe, to ensure that the refrigerant flowing through the first bend 310 does not cause resonance in the vibration damping section 300, and to reduce the vibration amplitude of the dehumidifier return pipe during operation, thereby reducing noise. In this embodiment, the central angle of the first bend 310 is 180°, and the radius of curvature of the first bend 310 is 2.5 times the outer diameter of the dehumidifier return pipe, thereby minimizing the vibration amplitude of the dehumidifier return pipe during operation and thus reducing noise. Specifically, the outer diameter of the dehumidifier return pipe is 7.94mm, the radius of curvature of the first bend 310 is 20mm, and the central angle is 180°. By modifying the structure of the first bend 310 on the vibration damping section 300, the vibration of the dehumidifier's return air pipe can be effectively reduced, thereby lowering noise and providing users with a better user experience.
[0057] Furthermore, such as Figure 1 and Figure 3 As shown, the other end of the first bend 310 is connected to the second return gas section 200 via the second arc-shaped pipe 322, thereby ensuring that the refrigerant can continuously and smoothly flow from the vibration damping section 300 into the second return gas section 200, and then enter the compressor 500 through the second return gas section 200. Further, the central angle of the second arc-shaped pipe 322 corresponds to the second included angle 312 between the second return gas section 200 and the vibration damping section 300, and the range of the second included angle 312 is 90°-110°. In this embodiment, as... Figure 3 and Figure 4 As shown, the second included angle 312 is 100°. Ensuring that the second included angle 312 between the second return gas section 200 and the vibration damping section 300 is between 90° and 110° effectively controls the speed at which the refrigerant enters the second return gas section 200 from the vibration damping section 300, thereby reducing vibration and noise.
[0058] Furthermore, one end of the second return gas section 200 is connected to the compressor 500, and the other end of the second return gas section 200 is connected to the vibration damping section 300. In this embodiment, as... Figure 1 As shown, the first end 210 of the second return gas section 200 is connected to the compressor 500, and the second end 220 of the second return gas section 200 is connected to the vibration damping section 300 through the second arc-shaped pipe 322, forming a second included angle 312 with the vibration damping section 300. In this embodiment, the first included angle 311 and the second included angle 312 are equal, and the second end 220 of the second return gas section is arranged parallel to the second end 120 of the first return gas section, thereby matching the symmetrical structure of the vibration damping section 300 and the first return bend 310, ensuring the smooth flow of refrigerant in the dehumidifier's return gas pipe.
[0059] Optionally, such as Figure 7 and Figure 8 As shown, in another embodiment, the dehumidifier's return air pipe is further wrapped with a vibration damping sleeve 600. The vibration damping sleeve 600 is an integral structure that completely wraps around the first return air section 100, the vibration damping section 300, and the second return air section 200 of the dehumidifier's return air pipe. This further absorbs the vibration generated when the refrigerant flows through the dehumidifier's return air pipe and reduces noise generated during operation, providing a better user experience. Optionally, the vibration damping sleeve 600 is a sponge vibration damping sleeve, which can simultaneously achieve vibration damping and sound absorption effects, resulting in better noise reduction.
[0060] The structure of the dehumidifier return pipe in this application can effectively control the flow velocity of the refrigerant in the dehumidifier return pipe. Under rated load, the noise generated by the dehumidifier during operation can be reduced to below 62dB, and the vibration half-amplitude of the dehumidifier surface can be controlled to below 25μm. At the same time, the low-frequency humming sound generated by the dehumidifier during operation can be eliminated, bringing a better user experience.
[0061] In summary, this application discloses a dehumidifier return pipe and a dehumidifier, wherein the dehumidifier return pipe is used to transport refrigerant from the evaporator to the compressor in the dehumidifier. The dehumidifier return pipe includes: a first return section, one end of which is connected to the evaporator, and the other end extending towards the compressor; a second return section, one end of which is connected to the compressor, and the other end extending towards the evaporator; and a vibration damping section, which is connected to the other ends of the first and second return sections respectively, to form a transport path from the evaporator to the compressor. The vibration damping section has a first bend, forming a first angle with the other end of the first return section, and a second angle with the other end of the second return section, wherein the first angle and the second angle are between 90° and 110°. The dehumidifier return pipe of this application can effectively control the refrigerant transport speed, reduce vibration and noise of the dehumidifier return pipe during operation, and provide a better user experience.
[0062] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
