As shown in fig. 1 to 3, in one embodiment, the refrigeration appliance 1 includes an outer shell 10 and an inner container 20. The inner side of the inner container 20 defines a storage compartment 21, and the outer container 10 is fitted over the outer side of the inner container 20, thereby forming a foamed layer between the outer container 10 and the inner container 20. The liner 20 is provided with a hollowed-out area 22.

With continued reference to fig. 1-3, the refrigeration unit 1 further includes a plate tube evaporator 30 and a temperature conduction plate 40. The plate-tube evaporator 30 is attached to the outer side of the inner container 20 and covers the hollow area 22, the temperature guide plate 40 is attached to the inner side of the inner container 20 and covers the hollow area 22, and a seal is formed between the temperature guide plate 40 and the inner side of the inner container 20 around the hollow area 22.

Specifically, the plate-tube evaporator 30 includes an evaporation tube 31 and an evaporation plate 32, and the evaporation tube 31 is formed on the evaporation plate 32. The evaporation plate 32 is attached to the outer side wall of the inner container 20, and the area of the evaporation plate 32 is larger than that of the hollow area 22, so that the evaporation plate 32 covers the hollow area 22 from the outer side of the inner container 20. The temperature guide plate 40 is attached to the inner sidewall of the inner container 20, and the area of the temperature guide plate 40 is larger than that of the hollow area 22, so that the hollow area 22 is covered by the temperature guide plate 40 from the inner side of the inner container 20.

In the scheme of this embodiment, by providing the hollow-out area 22 on the inner container 20, and enabling the plate-tube evaporator 30 and the temperature guide plate 40 to cover the hollow-out area 22 from the outer side of the inner container 20 and the inner side of the inner container 20, respectively, in the working process of the refrigeration apparatus 1, the plate-tube evaporator 30 can transmit the cold energy to the temperature guide plate 40 through the hollow-out area 22, and then the temperature guide plate 40 transmits the cold energy into the storage compartment 21 to cool the storage compartment 21. That is, the plate-tube evaporator 30 transfers the cooling capacity to the storage compartment 21 by using the temperature guide plate 40 having a better heat conduction effect, thereby improving the cooling efficiency of the plate-tube evaporator 30 and contributing to reducing the overall area of the plate-tube evaporator 30.

Moreover, because the heat conducting plate 40 and the inner container 20 form a seal, the water vapor in the storage chamber 21 cannot enter the plate-tube evaporator 30 and the area where the foaming layer is located through the hollow area 22, so that the phenomenon that the plate-tube evaporator 30 frosts to damage the foaming layer can be avoided. Meanwhile, the condition that defrosting water on the temperature guide plate 40 enters the foaming layer to cause the reduction of the heat preservation effect of the foaming layer or directly cause the damage of the heat preservation layer can be avoided.

As shown in conjunction with fig. 3, specifically, the first seal structure 50 includes a receiving groove 51 and a seal gasket 52. The accommodating groove 51 is formed on a side of the temperature guide plate 40 facing the hollow area 22. The sealing gasket 52 is arranged in the containing groove 51, and the sealing gasket 52 is in sealing fit with the temperature guide plate 40 and the inner container 20.

Specifically, the seal gasket 52 is made of a waterproof material such as EPDM (Ethylene Propylene Diene Monomer) sponge. The shape surrounded by the sealing pad 52 is similar to the shape of the hollow area 22, and the area of the shape surrounded by the sealing pad 52 is larger than the area of the hollow area 22, so that the sealing pad 52 can surround the periphery of the hollow area 22.

Meanwhile, the shape of the receiving groove 51 matches the outer shape of the packing 52. Therefore, after the temperature-guiding plate 40 is attached to the inner sidewall of the inner container 20, the accommodating groove 51 and the inner container 20 together hold the sealing gasket 52, one side of the sealing gasket 52 is in sealing engagement with the accommodating groove 51 (i.e., in sealing engagement with the temperature-guiding plate 40), and the other side of the sealing gasket 52 is in sealing engagement with the inner wall of the inner container 20, thereby forming a seal between the inner container 20 and the temperature-guiding plate 40.

Referring to fig. 2 and 3, in particular, the second sealing structure 60 is a waterproof double-sided tape, which surrounds the first sealing structure 50. One side of the second sealing structure 60 is bonded and sealed with the inner container 20, and the other side is bonded and sealed with the temperature guide plate 40.

In the solution of the present embodiment, by providing the first sealing structure 50 surrounding the hollow area 22 and the second sealing structure 60 surrounding the first sealing structure 50 between the temperature guide plate 40 and the inner container 20, a double seal is formed between the temperature guide plate 40 and the inner container 20, thereby being beneficial to ensuring the sealing effect between the temperature guide plate 40 and the inner container 20.

Further, by making the sealing gasket 52 and the accommodating groove 51 formed in the temperature guide plate 40 constitute the first sealing structure 50, not only the positioning effect of the assembly between the temperature guide plate 40 and the inner container 20 can be achieved, but also the surface area of the temperature guide plate 40 facing the storage compartment 21 is increased to a certain extent, so that the contact area with the air is increased, which is beneficial to improving the refrigeration efficiency.

Through setting up second seal structure 60 as waterproof double faced adhesive tape, when playing waterproof sealing effect, also can play the effect of fixed temperature guide plate 40 and inner bag 20.

It should be noted that the shape of the hollow area 22 may be a rounded rectangle, or may be various shapes such as a square, a hexagon, and the like, and accordingly, the shapes of the first sealing structure 50 and the second sealing structure 60 may also be adaptively adjusted.

It should be noted that a sealing structure such as a single seal or a triple seal may be employed between the inner container 20 and the temperature conduction plate 40.

As shown in fig. 2 and 3, in one embodiment, the refrigeration device 1 further includes a plurality of fins 70, and the plurality of fins 70 are disposed on a surface of the temperature guide plate 40 facing the inner side of the inner container 20. Specifically, a plurality of raised fins 70 are formed by punching holes in the fin plate. The fin plate is attached to the surface of the temperature guide plate 40 facing the inner side of the liner such that the fins 70 face the storage compartment 21.

In the scheme of this embodiment, by providing the plurality of fins 70 on the side of the temperature guide plate 40 facing the storage compartment 21, the plate-tube evaporator 30 can transmit the cold energy to the temperature guide plate 40 and the plurality of fins 70 through the hollow area 22, and then the temperature guide plate 40 and the plurality of fins 70 transmit the cold energy into the storage compartment 21 to cool the storage compartment 21, and the plurality of fins 70 increase the contact area with the air, thereby improving the refrigeration efficiency of the evaporator.

As shown in fig. 2 and 3, in an embodiment, a side of the temperature guiding plate 40 facing away from the hollow area 22 is provided with a concave portion 41, the concave portion 41 is located in the hollow area 22, and an outer side surface of the concave portion 41 is attached to the plate-tube evaporator 30.

Specifically, the portion of the temperature guide plate 40 in the hollow area 22 extends into the hollow area 22. In other words, with reference to the surface of the temperature guide plate 40 facing the hollow area 22, the portion of the temperature guide plate 40 in the hollow area 22 protrudes toward the hollow area 22. With reference to the surface of the temperature guide plate 40 facing the storage compartment 21, the portion of the temperature guide plate 40 in the hollow area 22 is recessed toward the hollow area 22, so as to form a recessed portion 41.

After the temperature guiding plate 40 and the inner container 20 are assembled in place, the recess 41 extends into the hollow area 22 and is attached to the portion of the plate-tube evaporator 30 covering the hollow area 22.

In the solution of this embodiment, the portion of the temperature guide plate 40 located in the hollow area 22 is attached to the plate-tube evaporator 30, so that on one hand, the cold energy of the plate-tube evaporator 30 can be better transmitted to the temperature guide plate 40, thereby being beneficial to improving the refrigeration efficiency. On the other hand, the recessed portion 41 not only increases the surface area of the surface of the temperature guide plate 40 facing the storage compartment 21, that is, the contact area with air, thereby being beneficial to improving the cooling capacity exchange efficiency and further improving the cooling efficiency.

Further, as shown in fig. 4, a plurality of fins 70 are provided in the recess 41. On the one hand, because the depressions 41 engage with the plate-tube evaporator 30, a better transfer of cold to the fins 70 and thus from the fins 70 into the storage compartment 21 is possible. On the other hand, the recess 41 forms a certain accommodation space, and the plurality of fins 70 makes the shape at the recess 41 more complicated. Therefore, the fins 70 and the recesses 41 cooperate with each other, so that the air can stay at the recesses 41 for a longer time, which is advantageous for the air and the fins 70 to sufficiently exchange the cold.

As shown in fig. 3 and 4, in one embodiment, the plurality of fins 70 are distributed in a plurality of rows in the up-down direction, the fins 70 in each row are arranged obliquely, and the inclination directions of the fins 70 of adjacent two rows are opposite. Specifically, in the present embodiment, the plurality of fins 70 are divided into three rows, the fins 70 in the uppermost row are inclined from the upper right to the lower left, the fins 70 in the middle row are inclined from the upper left to the lower right, and the fins 70 in the lowermost row are inclined from the upper right to the lower left.

In the scheme of this embodiment, the plurality of fins 70 are distributed in a plurality of rows, and the fins 70 in two adjacent rows have opposite inclination directions, so that the flow speed of the air between the fins 70 can be reduced, the retention time of the air between the fins 70 can be prolonged, sufficient cold exchange can be performed between the air and the fins 70, and the improvement of the refrigeration efficiency is facilitated.

As shown in fig. 1 and 2, in one embodiment, the refrigeration unit 1 further includes a cover plate 80 and a fan 90. The cover plate 80 covers the temperature guide plate 40 with a space therebetween. The fan 90 is disposed between the cover plate 80 and the temperature guide plate 40, and the fan 90 is located at an upper side of the plurality of fins 70.

Specifically, the cover plate 80 is disposed at a side of the temperature guide plate 40 facing the storage compartment 21 with a certain interval from the temperature guide plate 40 so that the blower 90 can be installed between the cover plate 80 and the temperature guide plate 40. The fan 90 is located above the plurality of fins 70.

Therefore, when the fan 90 is activated, the fan 90 can make the air in the fins 70 flow upward, then flow from the gap between the top of the cover plate 80 and the inner container 20 to the side of the cover plate 80 away from the temperature guide plate 40, and then flow from the gap between the bottom of the cover plate 80 and the inner container 20 to the fins 70 between the cover plate 80 and the temperature guide plate 40 again, thereby forming a circulation air path (refer to the flow direction schematic lines in fig. 1).

In the solution of the present embodiment, by providing the cover plate 80 and the fan 90 in the storage compartment 21, the fan 90 can form a circulating airflow in the storage compartment 21, so that the airflow continuously flows through the temperature guide plate 40 and the fins 70 to bring the cooling energy into the space of the entire storage compartment 21. Moreover, the fan 90 can drive the cold air flow upwards, and the cold air flow is prevented from sinking and concentrating towards the bottom of the storage compartment 21 to a certain extent, so that the cold air flow can be diffused in the storage compartment 21, the refrigeration efficiency can be improved, and the temperature uniformity in the storage compartment 21 can be improved.

In addition, in the present embodiment, the temperature guide plate 40 is provided with the recess 41, and the plurality of fins 70 are provided in the recess 41. Also, the plurality of fins 70 are distributed in a plurality of rows in the up-down direction, the fins 70 in each row are arranged obliquely, and the inclination directions of the fins 70 in adjacent two rows are opposite. The air path at the fin 70 is more complicated due to the structure, so that the flowing time of the air flow at the fin 70 is prolonged, more cold energy can be taken away by the air flow, and the refrigeration efficiency is improved.

Referring to fig. 1 and 2, a bent portion closer to the liner 20 is formed at a top end of the cover plate 80, and a bent portion closer to the liner 20 is formed at a bottom end of the cover plate 80. That is, the top portion of the cover plate 80 is bent toward the inner container 20, and the bottom portion of the cover plate 80 is bent toward the inner container 20. Thereby allowing the air flow to stay between the cover plate 80 and the temperature-guide plate 40 for a longer time so that the cool air is sufficiently exchanged.

Referring to fig. 1 and 2, in one embodiment, the sealing between the plate-tube evaporator 30 and the inner container 20 around the hollow area 22 includes applying waterproof glue between the plate-tube evaporator 30 and the inner container 20, or bonding the plate-tube evaporator 30 and the inner container 20 together by ultrasonic welding.

In the solution of this embodiment, by forming a seal between the plate-tube evaporator 30 and the inner container 20, the sealing effect on the hollow area 22 can be further improved, and the moisture in the storage chamber 21 is prevented from entering the foaming layer.

Referring to FIG. 3, in one embodiment, the plate tube evaporator 30 is provided with positioning holes 33, and the positioning holes 33 are formed in the evaporation plate 32. The outer side wall of the inner container 20 is provided with a positioning column, and when the plate-tube evaporator 30 and the inner container 20 are assembled in place, the positioning column is embedded into the positioning hole 33. Therefore, the positioning hole 33 and the positioning column can play a positioning role in assembling the plate-tube evaporator 30 and the inner container 20.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
