This not only affects the cleanliness of the refrigerator's interior but may also cause short circuits in electrical components.

[0003] In existing technologies, insulation materials are usually used to wrap the return air pipe to reduce condensation, but this method cannot completely solve the problem, especially in high humidity environments where condensation is still quite serious. Utility Model Content

[0004] In order to solve the technical problem of condensation on the return pipe of refrigerators in the prior art, a refrigeration device and refrigerator are provided that uses a water suction mechanism to move and absorb water from the outer wall of the return pipe to prevent condensation from dripping from the return pipe.

[0010] The water absorption mechanism includes a water absorption part and a driving part. The water absorption part is located on the driving part and has a mounting hole. The water absorption part is sleeved on the air return pipe through the mounting hole. The driving mechanism is connected to the driving part.

[0011] The driving mechanism includes a first magnetic part and a second magnetic part.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly.

[0031] In a refrigerator's refrigeration system, the return pipe is a crucial component connecting the evaporator and compressor. In low-temperature environments, condensation easily forms on the surface of the return pipe, causing water droplets to drip down the pipe. This not only affects the cleanliness of the refrigerator's interior but can also potentially cause short circuits in electrical components. Current technology typically uses insulation material to wrap the return pipe to reduce condensation, but this method does not completely solve the problem, especially in high-humidity environments where condensation remains a significant issue.

[0032] Therefore, this application provides a method such as Figures 1 to 4The refrigeration device shown includes: a compressor 1; an evaporator connected to the compressor 1 via a return pipe 2; a water-absorbing mechanism 3 movably mounted on the return pipe 2; and a drive mechanism 4 connected to the water-absorbing mechanism 3, which can move the water-absorbing mechanism 3 along the return pipe 2. By moving the water-absorbing mechanism 3 along the outer wall of the return pipe 2, it absorbs the condensation generated on the return pipe 2, thus preventing the condensation from accumulating and dripping onto the outer wall of the return pipe 2. This effectively improves the cleanliness of the refrigerator's interior and prevents dripping condensation from affecting the normal operation of other electrical components. Furthermore, since the return pipe 2 is located inside the compressor 1, the temperature inside the compressor 1 can dry the condensation absorbed by the water-absorbing mechanism 3, preparing it for the next absorption of condensation on the return pipe 2, thus improving the user experience of the refrigerator. It is important to emphasize that although the return pipe 2 is located inside the compressor 1 cavity, the temperature inside the compressor 1 cavity is not high when the refrigerator starts up, while the refrigerant temperature inside the return pipe 2 is also low. This still causes condensation to form on the outer wall of the return pipe 2. As the refrigerant continues to flow within the return pipe 2, the condensation on its outer wall will collect and drip. This is especially true when there is a height difference in the shape of the return pipe 2; condensation at higher levels will flow to lower levels, again causing condensation to collect and drip. Therefore, as the temperature inside the compressor 1 cavity rises to a certain level, the water suction mechanism 3 is needed to clean the outer wall of the return pipe 2. Wiping and absorbing water prevents condensation from dripping onto the return pipe 2. In other words, existing technologies use insulation material to wrap the return pipe 2 to block the conditions that cause condensation. However, this application does not directly prevent condensation from forming on the return pipe 2. Instead, it absorbs and treats the condensation promptly after it forms, using a method of guiding and consuming the condensation. This is completely opposite to the technical means in existing technologies. It also avoids the problem of condensation still occurring even after the insulation material is damaged, further ensuring the reliability of the refrigeration device and the user experience.

[0033] In one specific implementation, the water absorption mechanism 3 includes a water absorption part 31 and a driving part 32. The water absorption part 31 is located on the driving part 32, and the water absorption part 31 is provided with a mounting hole. The water absorption part 31 is sleeved on the return air pipe 2 through the mounting hole. The driving mechanism 4 is connected to the driving part 32. By using the driving part 32 to drive the water absorption part 31 to move, the water absorption part 31 can absorb and wipe water at all positions on the return air pipe 2, thereby removing condensation generated at any position on the return air pipe 2. This avoids the problem of condensation accumulating and dripping on the outer wall of the return air pipe 2, effectively improving the cleanliness of the refrigerator's internal environment and preventing dripping condensation from affecting the normal operation of other electrical components.

[0034] Specifically, the driving mechanism 4 includes a first magnetic part 41 and a second magnetic part 42. The first magnetic part 41 is located at one end of the return air pipe 2, and the second magnetic part 42 is located at the second end of the return air pipe 2. The water absorption mechanism 3 can move between the first magnetic part 41 and the second magnetic part 42, and both the first magnetic part 41 and the second magnetic part 42 can magnetically engage with the driving part 32. The magnetic field generated by the first magnetic part 41 and the second magnetic part 42 magnetically attracts the driving part 32, thereby forcing the driving part 32 to move. The first magnetic part 41 and the second magnetic part 42 generate a controllable magnetic field surrounding the entire return air pipe 2. By adjusting the direction of the magnetic field, the water absorption mechanism 3 can be controlled to move in different directions. Figure 3 As shown in the figure, the lines on the outside of the return air pipe are the magnetic lines of force generated by the drive mechanism.

[0035] In one implementation, when the first magnetic part 41 generates magnetic force, the second magnetic part 42 stops generating magnetic force. The driving part 32 is attracted by the magnetic force of the first magnetic part 41 and moves towards the first magnetic part 41. The movement of the driving part 32 can drive the movement of the water-absorbing part 31, thereby wiping the air return pipe 2 in the first direction. When the water-absorbing part 31 reaches a preset position close to the first magnetic part 41, the first magnetic part 41 stops generating magnetic force, and the second magnetic part 42 starts generating magnetic force. The driving part 32 is attracted by the magnetic force of the second magnetic part 42 and moves towards the second magnetic part 42. The movement of the driving part 32 can drive the movement of the water-absorbing part 31, thereby wiping the air return pipe 2 in the second direction. By alternating the operation of the first magnetic part 41 and the second magnetic part 42, the reciprocating movement of the water-absorbing part 31 on the air return pipe 2 is realized, ensuring the wiping effect of the air return pipe 2. Furthermore, by utilizing the first magnetic part 41 and the second magnetic part 42, the shape of the return air pipe 2 can be disregarded. In particular, when the shape of the return air pipe 2 is not a straight pipe, the first magnetic part 41 and the second magnetic part 42 can still act on the drive part 32 through the generated magnetic field, thereby ensuring the reliability of the movement of the water suction mechanism 3.

[0036] The water-absorbing part 31 is made of a highly absorbent material, such as a sponge, which can absorb a large amount of condensation and store it inside. Alternatively, it can be made of a material with fast drainage and low residue, such as absorbent resin. The absorbent resin can absorb the condensation and discharge and collect it at a set location using fast drainage, thereby avoiding the problem of water dripping at random locations in the return pipe 2 and ensuring the reliability of the refrigeration device.

[0037] The drive unit 32 is made of a high magnetic permeability material, which can ensure its reliable cooperation with the first magnetic part 41 and the second magnetic part 42. At the same time, the drive unit 32 and the water absorption part 31 are tightly connected to ensure the structural reliability of the water absorption mechanism 3.

[0038] Both the first magnetic part 41 and the second magnetic part 42 are formed by winding coils, preferably copper wires. The generation of a magnetic field is controlled by energizing and de-energizing the coils. The magnetic field strength can also be adjusted according to the number of coil turns, so that the first magnetic part 41 and the second magnetic part 42 can generate a magnetic field in a controllable manner, thereby making the movement of the water absorption mechanism 3 controllable.

[0039] In order to enable the water absorption mechanism 3 to be reused, the condensation inside the water absorption mechanism 3 needs to be consumed. Although the return pipe 2 is located inside the compressor 1 cavity, that is, the water absorption mechanism 3 is located inside the compressor 1 cavity, the temperature inside the compressor 1 cavity needs to gradually rise as the compressor 1 operates. The timing of condensation on the return pipe 2 is in the early stage of refrigerator startup, and the temperature inside the compressor 1 cavity is insufficient to dry the water absorption mechanism 3. Therefore, the refrigeration device also includes a limiting structure. The limiting structure is set on the part of the return pipe 2 near the compressor 1, and the limiting structure can limit the water absorption mechanism 3. The limiting structure restricts the water absorption mechanism 3 to stay in the position close to the compressor 1. The waste heat of the compressor 1 during operation is used to dry the water absorption mechanism 3, thereby improving the drying effect of the water absorption mechanism 3, so that the water absorption mechanism 3 can return to the state of being able to absorb water more quickly, which facilitates the next condensation removal of the return pipe 2.

[0040] Optionally, the return air pipe 2 is welded to the compressor 1, and the welding position between the return air pipe 2 and the compressor 1 constitutes the limiting structure. When connecting the return air pipe 2 and the compressor 1, the return air pipe 2 needs to be welded to the air inlet of the compressor 1. At this time, the maximum outer diameter of the weld formed during the welding process will inevitably exceed the return air pipe 2, while the inner diameter of the water suction mechanism 3 is approximately equal to the outer diameter of the return air pipe 2, so that the weld can achieve the effect of limiting the water suction mechanism 3.

[0041] When the water suction mechanism 3 removes the condensation on the return pipe 2, the water suction mechanism 3 can start from the limiting structure, slide along the end of the return pipe 2 away from the compressor 1, and then slide back along the return pipe 2 to the limiting structure. At this time, the condensation removal of the entire return pipe 2 has been completed. At the same time, the water suction mechanism 3 can also continue to be dried by the waste heat of the compressor 1 at the limiting structure, preparing for the next condensation removal.

[0042] In another embodiment (not shown in the figure), the driving mechanism 4 includes a driving component and a pull rope. One end of the pull rope is connected to the water absorption mechanism 3, and the other end is connected to the driving component. The driving component can drive the water absorption mechanism 3 to move via the pull rope. By pulling the pull rope with the driving component, the water absorption mechanism 3 is moved on the air return pipe 2. Taking a stepper motor as the driving component, there are two stepper motors, which are respectively arranged at both ends of the air return pipe 2. Each stepper motor is connected to the water absorption mechanism 3 via a pull rope. According to the movement requirements of the water absorption mechanism 3, one of the two stepper motors can work while the other follows. Compared with the previous embodiment, the reliability of the direct mechanical connection is higher than that of magnetic drive. However, for the complex-shaped air return pipe 2, the pull rope is easy to get tangled, while magnetic drive has higher reliability.

[0043] The refrigeration device also includes a control mechanism electrically connected to the drive mechanism 4, which can control the drive mechanism 4 according to a preset anti-condensation program. The control mechanism enables automated operation of the refrigeration device without manual intervention, improving the user experience. The anti-condensation program is pre-stored in the control mechanism, allowing the drive mechanism 4 to drive the water suction mechanism 3 to wipe the return air pipe 2 according to the program, thereby preventing dripping and reducing the energy consumption of the refrigeration device.

[0044] Optionally, the refrigeration device further includes a detection mechanism. This detection mechanism is capable of acquiring the ambient temperature of the space where the refrigeration device is located. The detection mechanism is electrically connected to the control mechanism, which can determine whether to activate the preset anti-condensation program based on the ambient temperature. By acquiring the ambient temperature, it can be determined whether condensation will occur on the outer wall of the return pipe 2. For example, if the ambient temperature is lower than a preset temperature value or if the temperature difference between the ambient temperature and the refrigerant inside the return pipe 2 exceeds a preset difference value, condensation may occur. If condensation is likely, the preset anti-condensation program is activated, and the return pipe 2 is wiped using the water absorption mechanism 3. If condensation does not occur, the preset anti-condensation program is not activated, reducing the energy consumption of the refrigeration device.

[0045] The refrigeration device also includes a detection mechanism, which can acquire the ambient humidity of the space where the refrigeration device is located. The detection mechanism is electrically connected to the control mechanism, which can determine whether to activate the preset anti-condensation program based on the ambient humidity. By acquiring the ambient humidity, it can be determined whether condensation will occur on the outer wall of the return pipe 2, for example, when the ambient humidity exceeds a preset humidity value. If it does, condensation may occur. When condensation is likely, the preset anti-condensation program is activated, and the water absorption mechanism 3 wipes the return pipe 2. If condensation does not occur, the preset anti-condensation program is not activated, reducing the energy consumption of the refrigeration device.

[0046] Ideally, the testing agency should simultaneously test the ambient temperature and humidity. If the ambient temperature is lower than the preset temperature value and the ambient humidity reaches the preset humidity value, condensation will occur, and the preset anti-condensation program will be activated. The water absorption mechanism 3 will be used to wipe the return air pipe 2. Otherwise, the preset anti-condensation program will not be activated to reduce the energy consumption of the refrigeration unit.

[0047] To ensure that the water-absorbing mechanism 3 can reliably wipe away condensation during its movement, and to prevent the water-absorbing mechanism 3 from being unable to completely absorb the condensation on the return air pipe 2, especially if the drying time of the water-absorbing mechanism 3 is short and the condensation absorbed in its previous movement is not completely dried and removed, the refrigeration device also includes a timing mechanism. This timing mechanism can acquire the time interval between two adjacent movements of the water-absorbing mechanism 3, and is electrically connected to the control mechanism. By controlling the time interval between two movements of the water-absorbing mechanism 3, it is ensured that the water-absorbing mechanism 3 is dried to a preset degree, thus ensuring the reliability of the wiping of the return air pipe 2 by the water-absorbing mechanism 3.

[0048] The timing mechanism needs to have a preset time interval t0, and the time interval t1 between two movements of the water absorption mechanism 3 needs to be greater than or equal to t0. This ensures the drying degree of the water absorption mechanism 3. The preset time interval t0 needs to be determined based on parameters such as the maximum length of the return air pipe 2 and the distance between the limit position of the water absorption mechanism 3 and the compressor 1.

[0049] A refrigerator, comprising the aforementioned refrigeration device.

[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
