Description

Technical Field

[0001] This invention relates to the field of refrigeration and freezing, and in particular to a refrigeration and freezing apparatus. Background Technology

[0002] Currently, refrigerators with ice-making compartments on the doors all transfer the cold air from the freezer compartment to the ice-making compartment through air ducts. This not only results in complex air duct structures, but also leads to condensation at the junction of the cabinet and door air ducts, long ice-making times, and the possibility of odor transfer between the ice-making and freezer compartments, affecting the cleanliness of the ice. Considering all these factors, the design needs to provide a refrigeration and freezing device with a reliable connection between the cabinet and door piping, allowing refrigerant to be introduced into the door. Summary of the Invention

[0003] One object of the present invention is to overcome at least one technical defect in the prior art and to provide a refrigeration and freezing device with reliable connection between the casing and the door piping.

[0004] A further objective of this invention is to improve the stability of the winder guide.

[0005] Another further objective of this invention is to extend the service life of the pipeline.

[0006] In particular, the present invention provides a refrigeration and freezing apparatus, comprising:

[0007] The enclosure is limited to having at least one storage compartment;

[0008] At least one door for opening and closing the at least one storage room;

[0009] The pipeline includes a housing portion disposed within the enclosure, a door portion disposed within one of the doors, and a connecting portion connecting the housing portion and the door portion; and

[0010] Multiple winders, including a housing winder fixed relative to the housing and a door winder fixed relative to the door portion; wherein

[0011] The housing winder and the door winder are configured such that, during the rotation of the door, a portion of the connecting portion is wound around one of the housing winder and the door winder, and a portion is detached from the other of the housing winder and the door winder.

[0012] Optionally, the door winding device is located on one side of the door portion near the rotation axis of the door.

[0013] Optionally, when the door body moves to its limit position in the direction that it is more wrapped around the door body winder towards the connecting part, the connecting part is in a tensioned state.

[0014] Optionally, the door winder has a limiting groove extending in its circumferential direction to restrict the movement of the connecting part in the axial direction of the door winder.

[0015] Optionally, the door winder is configured to rotate about its axis.

[0016] Optionally, the refrigeration and freezing apparatus further includes:

[0017] A pivot is configured to be fixedly connected to the door body, and the door body winder is sleeved on the pivot and can rotate around the pivot; and

[0018] A stop is provided at the end of the pivot shaft away from the door body to restrict the movement of the door body winder in its axial direction.

[0019] Optionally, the plurality of winders further include:

[0020] A positioning winder is configured to be fixed relative to the housing and located behind the housing winder and in front of the end of the housing portion used to connect the connecting portion; wherein

[0021] During the rotation of the door, a portion of the connecting part is configured to be wound around the positioning winder.

[0022] Optionally, the refrigeration and freezing apparatus further includes:

[0023] A cover plate is disposed above the box body and fixedly connected to the box body; wherein

[0024] The winder, which is fixed relative to the housing, is configured to be fixedly connected to the cover plate.

[0025] Optionally, the door body portion is configured to extend out from the outside of the rotation shaft hole of the door body and connect to the connecting portion.

[0026] Optionally, the door is provided with an ice-making chamber, and the piping includes at least one of a refrigerant pipe and a water supply pipe.

[0027] The refrigeration and freezing device of the present invention is provided with multiple winders fixed relative to the cabinet and the door respectively. Through the guiding effect of the winders, the pipeline is partially wound around one or more winders and partially unwound from one or more winders during the rotation of the door, so as to realize the smooth movement of the pipeline, avoid the bending and twisting of the pipeline, and improve the reliability of the pipeline connection between the cabinet and the door.

[0028] In particular, the pipes guided by the winder of the present invention do not need to pass through the rotating shaft hole of the door body. Instead, they can pass through a hole separately provided on the outside of the rotating shaft hole for connection. This reduces the size requirements of the rotating shaft hole of the door body and allows more and more types of pipes to be connected to the door body, thereby improving the richness of the door body's functions.

[0029] Furthermore, the door winding device of the present invention is located on the side of the door body near the rotation axis of the door body, which can improve the compactness of multiple winding devices, avoid excessively long pipes in the connection part, save costs, and reduce the loss of cold energy.

[0030] Furthermore, the connecting part of the present invention is configured to be in a tensioned state when the door body moves to the limit position in the direction of more winding around the door body winder, and a limit groove is provided to limit the pipeline, which can ensure that the pipeline does not detach from the winder during the rotation of the door body, realize the stable guidance of the winder to the pipeline, and thus improve the reliability of the pipeline connection.

[0031] Furthermore, the present invention enables the door winding device to rotate around its own axis, which reduces friction between the pipe and the winding device during the rotation of the door, thereby reducing pipe wear and extending pipe service life. It also reduces the resistance to door rotation, making the door rotation smoother.

[0040] Figure 1 This is a schematic isometric view of a refrigeration and freezing apparatus 100 according to an embodiment of the present invention, wherein the door 120 is in the open state; Figure 2 yes Figure 1 The schematic top view of the refrigeration and freezing unit 100 shown is taken along a horizontal plane, with the cover plate 170 removed to show the winder. Figure 3 yes Figure 2 A schematic enlarged view of region A in the center. See also Figures 1 to 3 The refrigeration and freezing apparatus 100 may include a housing 110 defining at least one storage compartment 111, and at least one door for opening and closing at least one storage compartment 111 respectively.

[0041] The refrigeration and freezing unit 100 may also include piping extending from the cabinet 110 to the door 120. The piping may include a cabinet portion 131 disposed in the cabinet 110, a door portion 132 disposed in a door 120, and a connecting portion 133 connecting the cabinet portion 131 and the door portion 132.

[0042] The housing part 131 and the door part 132 can be pre-placed inside the insulation layer and then connected and communicated through the connecting part 133.

[0043] In particular, the refrigeration and freezing device 100 may also include multiple winders for guiding the connecting portion 133 during the rotation of the door 120, so as to prevent the connecting portion 133 from bending or twisting.

[0044] Specifically, the multiple winders may include a housing winder 140 fixed relative to the housing 110 and a door winder 150 fixed relative to the door 120 corresponding to the door portion 132.

[0045] The housing winder 140 and the door winder 150 can be configured such that, during the rotation of the door 120, a portion of the connecting portion 133 is wound around one of the housing winder 140 and the door winder 150, and a portion is unwound from the other of the housing winder 140 and the door winder 150, so as to achieve smooth movement of the connecting portion 133 and improve the reliability of the pipeline connection between the housing 110 and the door 120.

[0046] In this invention, the length of the pipe wound around each winder can be less than the perimeter of the cross-section of the corresponding winder (i.e., the pipe is wound less than one turn relative to each winder).

[0047] The door body portion 132 can be configured to extend out from the outside of the rotation shaft hole 122 of the door body 120 and connect to the connecting portion 133, so as to reduce the size requirements of the rotation shaft hole 122 of the door body 120, and allow more and more types of pipes to be connected to the door body 120, thereby improving the richness of the functions of the door body 120.

[0048] The housing winder 140 and the door winder 150 can be one or more, to further improve reliability by guiding the pipeline multiple times through multiple winders, or to group different pipelines to different positions of the door 120.

[0049] In some embodiments, the door 120 may be provided with an ice-making chamber 121 for freezing water to form ice. In some embodiments, the door 120 may be provided with a water distributor for providing hot or cold water.

[0050] The piping may include at least one of the following: refrigerant piping for supplying cooling capacity to the ice-making room 121 or the water distributor, water supply piping, and electrical wiring.

[0051] Figure 4 yes Figure 1 The schematic top view of the refrigeration and freezing unit 100 shown is taken along a horizontal plane, with the door 120 closed and the cover 170 removed to show the winder. Figure 5 yes Figure 4 A schematic enlarged view of region B in the middle. See also Figures 3 to 5 The connecting part 133 can be configured to be in a tensioned state when the door body 120 moves to the limit position in the direction of the connecting part 133 winding more around the door body winder 150, so as to prevent the pipeline from detaching from the winder during the rotation of the door body 120.

[0052] In some embodiments, the door body winder 150 may be disposed on the side of the connecting end of the door body portion 132 near the rotation axis of the door body 120 to improve the compactness of multiple winders, avoid excessively long pipes in the connecting portion 133, save costs, and reduce the loss of cold energy.

[0053] In this embodiment, the connecting portion 133 can be configured to be in a tensioned state when the door 120 is in the closed state. That is, when the door 120 is in the closed state, the total length of the connecting portion 133 wound around the housing winder 140 and the door winder 150 can be greater than the total length of the door 120 when it is in the open state.

[0054] In other embodiments, the door winder 150 may be located on the side of the connecting end of the door portion 132 away from the rotation axis of the door 120, so that the door 120 may be provided with more door winders 150.

[0055] In this embodiment, the connecting portion 133 can be configured to be in a tensioned state when the door 120 is in the open state. That is, when the door 120 is in the closed state, the total length of the connecting portion 133 wound around the housing winder 140 and the door winder 150 can be less than the total length of the door 120 when it is in the open state.

[0056] In some embodiments, the plurality of winders may further include a positioning winder 160 fixed relative to the housing 110. The positioning winder 160 may be disposed on the rear side of the housing winder 140 and the front side of the connecting end of the housing portion 131. That is, the positioning winder 160 may be closer to the connecting end of the housing portion 131 relative to the housing winder 140.

[0057] During the rotation of the door 120, a portion of the connecting part 133 can be wound around the positioning winder 160 to further prevent the pipe from twisting and further improve the reliability of the pipe connection between the housing 110 and the door 120.

[0058] The refrigeration and freezing unit 100 may also include a cover plate 170 disposed above the cabinet 110 and fixedly connected to the cabinet 110. The winders (cabinet winder 140 and positioning winder 160) fixed relative to the cabinet 110 may be configured to be fixedly connected to the cover plate 170, so that the position design of the winders can be more flexible and the positioning and installation of the winders can be facilitated.

[0059] Figure 6 This is a schematic cross-sectional view of the fixing structure of a door winding device 150 according to an embodiment of the present invention. See also Figure 6 In some embodiments, the door winder 150 may have a limiting groove 151 extending in its circumferential direction to limit the movement of the connecting portion 133 in the axial direction of the door winder 150, so as to prevent the pipeline from detaching from the winder during the rotation of the door 120.

[0060] The door body winder 150 can be configured to rotate around its axis to reduce friction between the pipe and the winder during the rotation of the door body 120, thereby reducing pipe wear, extending pipe service life, and reducing resistance to door body 120 rotation, making door body 120 rotation smoother.

[0061] The refrigeration and freezing device 100 may also include a rotating shaft 152 and a stop 153. The rotating shaft 152 may be fixedly connected to the door body 120, and the door body winder 150 may be sleeved on the rotating shaft 152 and rotate around the rotating shaft 152.

[0062] The stop 153 may be provided at the end of the pivot 152 away from the door body 120 to limit the movement of the door body winder 150 in its axial direction, so as to prevent the door body winder 150 from disengaging from the pivot 152.

[0063] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
