Detailed Description

Fig. 1 is a schematic isometric view of a refrigeration freezer 100 according to one embodiment of the invention, with a door 120 in an open position; fig. 2 is a schematic top view of the refrigerated freezer 100 of fig. 1 taken in the horizontal plane with the cover plate 170 removed to show the winder; fig. 3 is a schematic enlarged view of the region a in fig. 2. Referring to fig. 1 to 3, the refrigerating and freezing apparatus 100 may include a cabinet 110 defining at least one storage compartment 111, and at least one door body for opening and closing the at least one storage compartment 111, respectively.

The refrigerator-freezer 100 may further include a duct extending from the cabinet 110 to the door 120. The duct may include a case portion 131 provided to the case 110, a door portion 132 provided to one door 120, and a connection portion 133 connecting the case portion 131 and the door portion 132.

The case portion 131 and the door portion 132 may be pre-disposed in the insulating layer and connected and communicated through the connection portion 133.

In particular, the refrigerating and freezing device 100 may further include a plurality of winders for guiding the connection portion 133 during the rotation of the door 120 to prevent the connection portion 133 from bending and twisting.

Specifically, the plurality of winders may include a chest winder 140 fixed with respect to the chest 110 and a door winder 150 fixed with respect to the door 120 corresponding to the door portion 132.

The chest winder 140 and the door winder 150 may be configured such that a portion of the connection portion 133 is wound around one of the chest winder 140 and the door winder 150 and a portion is separated from the other of the chest winder 140 and the door winder 150 during the rotation of the door 120, so as to achieve smooth movement of the connection portion 133 and improve the reliability of the pipe connection between the chest 110 and the door 120.

In the present invention, the length of the tubing wound around each winder may be less than the circumference of the cross-section of the corresponding winder (i.e. the tubing is wound less than one revolution relative to each winder).

The door portion 132 can be arranged to penetrate out of the outer side of the rotating shaft hole 122 of the door 120 and connected with the connecting portion 133, so that the size requirement of the rotating shaft hole 122 of the door 120 is reduced, more pipelines in quantity and types are connected to the door 120, and the function richness of the door 120 is further improved.

The box winder 140 and the door winder 150 may be one or more than one, respectively, so as to further improve reliability by guiding the pipelines multiple times through multiple winders, or to guide different pipelines to different positions of the door 120 by grouping.

In some embodiments, the door 120 may be provided with an ice making compartment 121 for freezing water to form ice cubes. In some embodiments, the door 120 may be provided with a water dispenser for providing hot or cold water.

The piping may include at least one of a refrigerant pipe for supplying cooling power to the ice making compartment 121 or the water dispenser, a water supply pipe, and an electrical connection.

Fig. 4 is a schematic top view of the refrigeration freezer 100 of fig. 1 taken in the horizontal plane with the door 120 in a closed state and the cover 170 removed to show the winder; fig. 5 is a schematic enlarged view of the region B in fig. 4. Referring to fig. 3 to 5, the connection part 133 may be disposed in a tensioned state when the door 120 moves to a limit position in a direction in which the connection part 133 is wound more around the door winder 150, so as to prevent the duct from being separated from the winder during the rotation of the door 120.

In some embodiments, the door winder 150 may be disposed on a side of the connection end of the door portion 132 close to the rotation axis of the door 120, so as to improve the compactness of the plurality of winders, avoid the overlong pipeline of the connection portion 133, save the cost, and reduce the dissipation of the cooling energy.

In this embodiment, the connection portion 133 may be provided in a tensioned state when the door body 120 is in the closed state. That is, when the door 120 is in the closed state, the total length of the connection part 133 wound around the body winder 140 and the door winder 150 may be greater than the total length of the door 120 in the open state.

In other embodiments, the door winder 150 may be disposed on a side of the connection end of the door portion 132 away from the rotation axis of the door 120, so that more door winders 150 may be disposed on the door 120.

In this embodiment, the connection portion 133 may be provided in a tensioned state when the door body 120 is in the open state. That is, when the door 120 is in the closed state, the total length of the connection part 133 wound around the body winder 140 and the door winder 150 may be less than the total length of the door 120 in the open state.

In some embodiments, the plurality of winders may further include a positioning winder 160 fixed relative to the case 110. The positioning winder 160 may be provided at the rear side of the case winder 140, the front side of the connection end portion of the case portion 131. That is, the positioning winder 160 may be closer to the connection end of the case portion 131 than the case winder 140.

During the rotation of the door 120, a portion of the connection portion 133 may be configured to be wound around the positioning winder 160, so as to further prevent the pipeline from twisting, and further improve the reliability of the pipeline connection between the cabinet 110 and the door 120.

The refrigerating and freezing device 100 may further include a cover plate 170 disposed above the case 110 and fixedly coupled to the case 110. The winders (the case winder 140 and the positioning winder 160) fixed with respect to the case 110 may be provided to be fixedly connected with the cover plate 170, so that the position design of the winder may be more flexible, facilitating the positioning installation of the winder.

Fig. 6 is a schematic sectional view of a fixing structure of door body winder 150 according to an embodiment of the present invention. Referring to fig. 6, in some embodiments, the door body winder 150 may be formed with a stopper groove 151 extending in a circumferential direction thereof to restrict movement of the connection portion 133 in an axial direction of the door body winder 150 to prevent the duct from being separated from the winder during rotation of the door body 120.

The door winder 150 can be set to rotate around the axis direction of the door winder so as to reduce the friction between the pipeline and the winder in the rotating process of the door 120, further reduce the loss of the pipeline, prolong the service life of the pipeline, reduce the rotating resistance of the door 120 and enable the door 120 to rotate more smoothly.

The refrigeration freezer 100 may further include a spindle 152 and a stop 153. The rotating shaft 152 may be fixedly connected to the door 120, and the door winder 150 is sleeved on the rotating shaft 152 and can rotate around the rotating shaft 152.

The stop 153 may be disposed at an end of the rotating shaft 152 far from the door 120, and is used for limiting the movement of the door winder 150 in the axial direction thereof, so as to prevent the door winder 150 from disengaging from the rotating shaft 152.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
