Referring to fig. 1, the refrigerating and freezing apparatus 100 may include a cabinet 110 defining at least one storage compartment 111, at least one door for opening and closing the at least one storage compartment 111, and a duct. In the present invention, at least one is one, two, or more than two.

The duct may include a body portion 130 at least partially provided to the body 110, a door portion provided to one door 120, and a connection portion 150 connecting the body portion 130 and the door portion.

The body portion 130 and the door portion may be pre-fixed to the insulating layer and then connected and communicated through the connection portion 150.

The connection portion 150 may be connected to the door portion inside the door 120 and extend to the outside of the door 120 to be connected to the cabinet portion 130.

The connection part 150 may have certain flexibility to prevent the pipeline from being damaged during the rotation of the door body 120, thereby improving the reliability of pipeline connection.

The door 120 may be provided with an ice making compartment 122 for freezing water to form ice cubes. The door 120 may be provided with a water dispenser 129 for supplying hot or cold water.

The piping may include at least one of a refrigerant pipe 151 of a refrigeration system and a water supply pipe 152 to provide cooling capacity and/or water supply to the ice making compartment 122 or the water dispenser 129.

The following describes an embodiment of the present invention in detail by taking a refrigerant pipe 151 of a refrigeration system as an example.

FIG. 2 is a schematic isometric view of a door 120 according to one embodiment of the present invention, with a portion of the outer shell 121 of the door 120 removed to show the internal structure; FIG. 3 is a schematic enlarged view of region A in FIG. 2; fig. 6 is a schematic isometric view of a door 120 according to another embodiment of the present invention, wherein an outer shell 121 of the door 120 is removed to show the interior structure. Referring to fig. 1 to 3 and 6, the door portion may extend at least partially into the ice making compartment 122 to improve ice making efficiency.

The door portion may include an evaporation pipe 141 disposed in the ice making compartment 122, and a transmission pipe 142 disposed in the insulation layer and connecting the evaporation pipe 141 and the connection portion 150 to provide cold energy to the ice making compartment 122.

The transmission pipe 142 can be bent and extended in a serpentine manner in the door body 120 to arrange longer pipelines in the same door body space, which is convenient for cold quantity control.

A water dispenser 129 may be disposed below ice-making compartment 122 and provided with a cavity recessed rearward and in contact with ambient air. The transport tubes 142 may be partially disposed on both lateral sides of the cavity to arrange longer tubes within the same door volume and avoid excessive accumulation of tubes.

The transport tube 142 may be spaced from the outer wall of the door 120 near the ambient air to prevent condensation on the outer wall of the door 120.

The delivery pipe 142 may include a refrigerant inlet pipe 142a and a refrigerant outlet pipe 142 b. At least a portion of the refrigerant inlet pipe 142a of the delivery pipe 142 near the evaporation pipe 141 may be attached to the refrigerant outlet pipe 142b of the delivery pipe 142 to improve heat exchange efficiency.

The space between the refrigerant inlet tube 142a of the delivery tube 142 and the outer wall of the door 120 near the ambient air may gradually increase along the extension path thereof toward the direction passing through the evaporation tube 141, so as to effectively prevent the outer wall of the door 120 from being condensed. That is, the interval between the end of the refrigerant inlet pipe 142a connected to the connection part 150 and the outer wall is smaller than the interval between the end of the refrigerant inlet pipe 142a connected to the evaporation pipe 141 and the outer wall.

A vacuum insulation panel 126 may be disposed between an outer wall of the door 120 adjacent to the ambient air and an end of the refrigerant inlet pipe 142a adjacent to the evaporation pipe 141 to improve heat insulation performance and prevent condensation.

The length of the refrigerant inlet pipe 142a of the delivery pipe 142 may be greater than or equal to 2m, for example, 2m, 2.5m, or 3 m. The number of the refrigerant inlet pipes 142a of the delivery pipe 142 may be plural, for example, two or three. The refrigerant inlet pipe 142a may serve as a throttling element for throttling the refrigerant flowing therethrough.

By arranging the plurality of refrigerant inlet pipes 142a with specific length and internal diameter, the invention not only can more flexibly control the refrigerant flow of the evaporating pipe 141 and further more flexibly and accurately control the ice making speed and the ice block quality, but also can reduce the condensation problem of the part of the connecting part 150 positioned at the outer side of the door body 120, prevent condensed water from dripping to pollute the indoor environment and avoid potential safety hazard.

Alternatively, the number of the refrigerant inlet pipes 142a may be one.

The spacing between the transfer tube 142 and the outer wall of the door 120 can be controlled by the thickness of the mounting block 125.

Each card slot may include a receiving portion 1251 and a lead-in portion 1252. The transfer pipe 142 may be configured to slide into the accommodating portion 1251 via the introduction portion 1252 and be clamped in the accommodating portion 1251. Wherein the width of the introduction part 1252 may be smaller than the outer diameter of the corresponding transfer tube 142 to limit the movement of the transfer tube 142 in the radial direction of the accommodation part 1251.

When the refrigerant inlet tube 142a is attached to the refrigerant outlet tube 142b, the width of the guiding portion 1252 of the locking groove may be smaller than the diameter of the refrigerant outlet tube 142 b.

The locking grooves of the plurality of fixing blocks 125 may have at least two extending directions to restrict the movement of the transfer pipe 142 in the axial direction of the accommodating part 1251. In the illustrated embodiment, the catching grooves of a portion of the fixing block 125 extend in a vertical direction, and the catching grooves of a portion of the fixing block 125 extend in a horizontal direction.

The number of the card slots of each fixing block 125 may be less than or equal to two to prevent the fixing block 125 from occupying an excessively large space.

In some embodiments, the fixture may include a fixture mount 124. An end of the transfer pipe 142 near the evaporation pipe 141 may be fixed to the fixing bracket 124 and extend into the ice making compartment 122 so as to be connected to the evaporation pipe 141.
