Referring to fig. 1 to 5, fig. 2 is an exploded view of a refrigerator 10 according to an embodiment of the present invention, fig. 3 is a schematic view of a partial section of a cooling pipe 300 in the refrigerator 10 according to an embodiment of the present invention, fig. 4 is a longitudinal sectional view of the refrigerator 10 according to an embodiment of the present invention, and fig. 5 is a partially enlarged view of a portion a in fig. 4. In some embodiments, the refrigerator 10 may further include a carrier plate 200 and a cooling tube 300.

The support plates 200 may be disposed in the storage compartment of one of the inner containers 100, a protrusion 210 is formed at a rear end of each of the support plates 200, and the refrigerating tube 300 is connected to an evaporator of the refrigerator 10, that is, a refrigerant in the evaporator may flow into the refrigerating tube 300, so that the refrigerating tube 300 has a refrigerating function. The cooling pipe 300 is inserted into the inner container 100, and a clamping portion 310 for clamping the protrusion 210 is formed at the rear wall 130 of the inner container 100 by bending and coiling, so as to transmit the cooling capacity of the cooling pipe 300 to the carrier plate 200.

In the present embodiment, the carrier plate 200 may be horizontally disposed in the storage compartment for carrying food or other articles, referring to fig. 3, the clamping portion 310 may be formed by a first clamping section 312 horizontally and transversely extending and a second clamping section 314 extending from the first clamping section 312 by turning 180 °, a clamping gap is formed between the first clamping section 312 and the second clamping section 314, and the protrusion 210 extends into the clamping gap, so that the carrier plate 200 is clamped by the clamping portion 310.

Since the clamping portion 310 is formed by the cooling pipe 300 and the cooling pipe 300 is connected to the evaporator, the cooling capacity of the cooling pipe 300 can be transmitted to the carrying board 200, that is, the carrying board 200 also has the function of transmitting the cooling capacity, and finally the food or other objects placed on the carrying board 200 are cooled.

Further, the clamping gap may also be configured such that the gap is indirectly smaller than the thickness of the protrusion 210, so that the protrusion 210 can be sufficiently in contact with the first clamping section 312 and the second clamping section 314, improving heat transfer efficiency.

Further, the tube type of the refrigerant tube 300 may be flat, and the surfaces of the first clamping section 312 and the second clamping section 314 contacting the protrusion 210 are wider, which not only increases the contact area between the clamping portion 310 and the protrusion 210 and improves the heat exchange effect, but also enables the protrusion 210 to be clamped more stably.

Referring further to fig. 5, the rear end of the protrusion 210 may also be configured as a tip to facilitate insertion into the clamping gap.

Further, the number of the clamping parts 310 may be greater than or equal to the number of the loading plates 200. When the number of the clamping parts 310 is greater than that of the bearing plates 200, the clamping parts 310 may be sequentially arranged along the height direction of the storage compartment, so that a user can adjust the distance between two adjacent bearing plates 200 according to the volume of the food material.

Referring to fig. 2 to 4, 6 and 7, fig. 6 is a partially enlarged view of a portion B of fig. 4, and fig. 7 is a bottom view of a heat exchanger 500 of the refrigerator 10 according to an embodiment of the present invention. In some embodiments, the refrigerator 10 may further include a drawer-type container 400 and a heat exchanger 500, the drawer-type container 400 is located below the loading plate 200 and is movable between a retracted position retracted into the storage compartment and an extracted position extracted out of the storage compartment, the heat exchanger 500 is directly or indirectly fixed to the bottom wall 110 of the inner container 100 and is located below the drawer-type container 400, and a partial section of the refrigeration tube 300 is penetrated and wound in the heat exchanger 500, the drawer-type container 400 is configured such that when in the retracted position, the bottom plate 410 of the drawer-type container 400 abuts against the upper surface of the heat exchanger 500 to transfer the refrigeration energy of the refrigeration tube 300 to the drawer-type container 400 through the heat exchanger 500.

Referring to fig. 3 and 6, since the heat exchanger 500 is located on the bottom wall 110 of the inner container 100, the cooling tube 300 may first extend downward after the plurality of clamping portions 310 are formed on the rear wall 130 of the inner container 100, then extend forward to above the bottom wall 110 of the inner container 100, and finally penetrate through the inside of the heat exchanger 500, so as to transfer the cooling tube of the cooling tube 300 to the heat exchanger 500.

Referring to fig. 7, the lower surface of the heat exchanger 500 is recessed inward to form a through groove for receiving the second clamping portion 310, so that the refrigerant pipe 300 is inserted into the interior of the heat exchanger 500. In addition, the through groove can be coiled, so that the relative positions of the refrigeration pipe 300 and the heat exchanger 500 can be fixed, the contact path of the refrigeration pipe 300 and the heat exchanger 500 can be prolonged, and the heat exchange efficiency is improved.

In some embodiments, the heat exchanger 500 may be directly disposed on the bottom wall 110 of the inner container 100 and extend upward such that the refrigeration tube 300 is inserted therein, and such that the bottom plate 410 abuts against an upper surface of the heat exchanger 500 when the drawer-type container 400 is in the retracted position.

Referring to fig. 4 and 6, in some other embodiments, the heat exchanger 500 may be indirectly disposed on the bottom wall 110 of the inner container 100. Specifically, the refrigerator 10 may further include a fixing block 600, the fixing block 600 is formed on the bottom wall 110 of the inner container 100, and an installation groove is formed at an upper portion of the fixing block 600, and the heat exchanger 500 is fixed in the installation groove.

That is, the heat exchanger 500 is disposed on the bottom wall 110 of the inner container 100 through the fixing block 600, and the fixing block 600 is preferably made of a heat insulating material (e.g., a heat insulating plastic), so that the fixing block 600 not only plays a role of mounting the heat exchanger 500, but also prevents the cold energy of the heat exchanger 500 from being transmitted to the bottom wall 110 of the inner container 100, thereby reducing energy loss.

Referring to fig. 4, 8 and 9, fig. 8 is a schematic view of an inner container 100 of a refrigerator 10 according to an embodiment of the present invention, and fig. 9 is a partially enlarged view of C of fig. 8. Further, the drawer-type container 400 may further include a drawer body 420, and the drawer body 420 is erected around the bottom plate 410, so that the drawer body 420 and the bottom plate 410 enclose a storage cavity.

The outer sides of the two side walls 120 of the drawer body 420 are respectively provided with a sliding rail 422, the two side walls 120 of the liner 100 are respectively provided with a slideway 122 for the sliding rail 422 to slide therein, and the lower wall surface 124 of each slideway 122 is provided with an inclined section 124a extending from the back to the front upwards, so that the drawer-type container 400 integrally moves upwards during the movement from the retracted position to the extracted position, and the bottom plate 410 is separated from the heat exchanger 500.

That is, when the drawer-type container 400 is in the retracted position, the bottom plate 410 of the drawer-type container 400 can just abut against the upper surface of the heat exchanger 500, and when a user draws the drawer-type container 400 outward, because the chute 122 has the inclined section 124a, the slide rail 422 moves upward under the constraint of the chute 122, so as to drive the entire drawer-type container 400 to move upward, and the bottom plate 410 is timely separated from the heat exchanger 500, so as to avoid the scratch between the heat exchanger 500 and the bottom plate 410 during the drawing process.

Referring to fig. 10, fig. 10 is a top view of a carrier plate 200 in a refrigerator 10 according to an embodiment of the present invention, wherein a dotted line represents a vacuum heat exchange cavity 220 inside the carrier plate 200. In some embodiments, the loading plate 200 and/or the bottom plate 410 are configured as a soaking plate, the soaking plate may be made of a metal with relatively high thermal conductivity (e.g., copper metal, etc.), a plurality of vacuum heat exchange cavities 220 extending in the front-back direction are formed in the soaking plate, a heat exchange medium is filled in the vacuum heat exchange cavities 220, and the heat exchange medium may be pure water, so that the cold energy is transferred along the extending direction of the vacuum heat exchange cavities 220 by using the heat exchange medium.

Because the pressure in the vacuum heat exchange cavity 220 is relatively low (in a vacuum state or a state close to the vacuum state), the evaporation temperature of the heat exchange medium is lower than that in a normal state, when a certain area of the soaking plate is heated, the heat exchange medium in the vacuum heat exchange cavity 220 is evaporated in a vacuum environment to form gaseous steam, and simultaneously absorbs heat, and when the gaseous steam meets a relatively cold area in the vacuum heat exchange cavity 220, the gaseous steam is condensed into a liquid state to release heat, so that the heat transfer is realized. In addition, capillary tubes can be pre-arranged in the vacuum heat exchange cavity 220 of the soaking plate, and the heat exchange medium condensed into liquid can return to the original position under the adsorption action of the capillary tubes to start the next heat transfer.

Since the bottom plate 410 of the loading plate 200 can be used to carry food, when food is prevented from being placed on the loading plate 200 or the bottom plate 410, the area is heated by the food, so that the heat exchange medium is rapidly evaporated into a gaseous state and transferred to a cooler area, and heat is released, i.e., the heat exchange medium transfers cold along the extending direction of the vacuum heat exchange cavity 220.

In addition, since the cooling tubes 300 are disposed at the rear end of the carrying plate 200 and below the bottom plate 410 (when the drawer-type container 400 is in the retracted position), the temperature difference between the heated region and the cooler region of the carrying plate 200 or the bottom plate 410 is increased, so that the heat exchange medium is transferred more quickly and the heat exchange efficiency is higher.

Referring to fig. 11, fig. 11 is an enlarged longitudinal sectional view of a loading plate 200 in a refrigerator 10 according to an embodiment of the present invention. Further, a plurality of raised heat dissipation fins 222 are formed in each vacuum heat exchange cavity 220 to increase the heat transfer area of the vacuum heat exchange cavity 220, and further improve the heat transfer efficiency of the soaking plate.

Referring to fig. 5 and 8, the rear wall 130 of the inner container 100 is formed with a first receiving groove 132 for receiving the clamping portion 310, and the first receiving groove 132 is open toward the front to expose the clamping portion 310, so that the protrusion 210 is clamped by the clamping portion 310 after extending into the first receiving groove 132.

Referring to fig. 3 and 8, the refrigeration tube 300 may further include a vertical section 320, the vertical section 320 extends upward from the bottom wall 110 of the inner container 100, the clamping portion 310 is formed at one side of the vertical section 320, the rear wall 130 of the inner container 100 is provided with a second receiving groove 134 for receiving the vertical section 320, the second receiving groove 134 extends vertically and is open towards the front, and the second receiving groove 134 is communicated with the first receiving groove.

The refrigeration tube 300 can be pre-manufactured according to the position distribution of the first receiving groove 132 and the second receiving groove 134, the clamping portion 310 and the vertical section 320 of the manufactured refrigeration tube 300 are correspondingly installed in the first receiving groove 132 and the second receiving groove 134, and then the back plate 700 is used to cover the second receiving groove, so as to ensure that the inner wall of the inner container 100 is relatively complete.

Referring to fig. 8, the two side walls 120 of the inner container 100 are respectively provided with overlapping protrusions 126 for erecting the bearing plate 200, and the two side walls 120 of the inner container 100 are respectively provided with positioning slots 128 for positioning the front and rear positions of the bearing plate 200.

When the loading plate 200 is installed, the loading plate 200 is placed on the overlapping protrusion 126 and pushed inward, and when two corners of the rear end of the loading plate 200 are clamped into the positioning grooves 128, the protrusion 210 of the loading plate 200 just extends into the first receiving groove 132 and is clamped by the clamping portion 310, so that the loading plate 200 is fixed in all directions.

According to the refrigerator 10 of the present invention, since the protruding portion 210 is formed at the rear end of the carrier plate 200, the cooling pipe 300 is connected to the heat exchange pipeline of the evaporator of the refrigerator 10, the cooling pipe 300 is inserted into the inner container 100, and the clamping portion 310 for clamping the protruding portion 210 is formed at the rear wall 130 of the inner container 100 by bending and coiling, when the protruding portion 210 of the carrier plate 200 is clamped by the carrier plate 200, the carrier plate 200 has a cold conducting function, a cold quantity transmission path is increased, and the temperature of the storage compartment is more uniform.

Further, the loading plate 200 and/or the bottom plate 410 are configured as a soaking plate, the area on the loading plate 200 or the bottom plate 410 where the food is placed is heated, the heat exchange medium is evaporated and transferred to the cooler area, i.e. the cold energy is transferred along the extending direction of the vacuum heat exchange cavity 220 of the soaking plate, so that the temperature of the soaking plate is more uniform.
