DETAILED DESCRIPTION

[0036] The present application will be described in detail below with reference to specific embodiments shown in the drawings.

[0037] In each of the drawings of the present application, certain dimensions of structures or parts are enlarged relative to other structures or parts for the purpose of illustration, and thus are merely used to illustrate the basic structure of the subject matter of the present application.

[0038] It should be understood that although the terms "first", "second", "third", etc. can be used herein to describe various elements, structures or parameters, these described objects should not be limited by these terms. These terms are only used to distinguish one described object from another.

[0039] Referring to FIG. 1, the refrigeration equipment 100 comprises a cabinet 1, a door body 2, a storage compartment 3, an evaporation pipe 4, a uniform temperature module 5, a first air guide member 52, a second air guide member 53, a third air guide member 54, a fourth air guide member 55, a fan assembly 56, an air return member 6, a cover plate 62, a first side plate 63, a second side plate 64, a basket 7 and a gap part 8. Figures 1 to 3As shown, an embodiment of the present application provides a refrigeration equipment 100, which comprises a cabinet 1, a door body 2 and a refrigeration unit. The cabinet 1 has a storage compartment 3 with an opening, and the door body 2 is used to open or close the opening of the storage compartment 3.

[0040] The refrigeration equipment 100 in the embodiment is a direct-cooling refrigeration equipment, which uses direct-cooling mode to provide cooling for the items stored in the storage compartment 3. The refrigeration equipment 100 can be specifically configured as a refrigerator, a freezer, a wine cabinet or the like, and is particularly a large-capacity refrigeration equipment. In the embodiment, the refrigeration equipment 100 is taken as a horizontal freezer for example to be described.

[0041] In combination Figures 4 to 6 , specifically, the refrigeration unit comprises a compressor, a condenser, a throttling device and an evaporator connected in sequence, the cabinet 1 comprises an inner container 11 and a shell 12 arranged outside the inner container 11, the inner container 11 defines the storage compartment 3, and the evaporator comprises an evaporating pipe 4 wound around the outer periphery of the inner container 11. The evaporating pipe 4 transmits the cold energy to the storage compartment 3 through the inner container 11 by natural radiation, so as to cool the items stored in the storage compartment 3.

[0042] This natural radiation cooling mode in which the evaporating pipe 4 is wound around the outer periphery of the inner container 11 transmits the cold energy from the inner container 11 to the middle region of the storage compartment 3. However, the space in the storage compartment 3 is usually large, which can cause a large temperature difference between the regions in the storage compartment 3 and poor temperature uniformity. In addition, the storage compartment 3 has an opening, and especially when the door body 2 is opened, the cold energy at the opening of the storage compartment 3 is lost more to the outside, which can cause the temperature of the region close to the opening of the storage compartment 3 to be obviously higher than that of the region close to the inner container 11, and further exacerbate the temperature non-uniformity in the storage compartment 3.

[0043] Referring to Figure 4 and Figure 5 , the refrigeration equipment 100 further comprises a temperature equalization module 5 arranged in the storage compartment 3. The temperature equalization module 5 is connected with the inner container 11 and exchanges heat with the inner container 11. The temperature equalization module 5 comprises a shell 12 and an air duct formed in the shell 12. An air outlet 51 of the air duct is arranged at the opening of the storage compartment 3, so that the cold energy generated by the evaporating pipe 4 can be transmitted to the region close to the opening of the storage compartment 3 through the heat exchange channel in the return air piece 6 and the air duct in the temperature equalization module 5, and the cold energy can flow from the region close to the opening of the storage compartment 3 to the return air piece, thereby improving the uniformity of the cold energy distribution in the storage compartment 3.

[0044] Further, the refrigeration equipment 100 further comprises a return air piece 6 arranged in the storage compartment 3. The return air piece 6 is connected with the inner container 11, and a heat exchange channel is formed between the return air piece 6 and the inner container 11. The heat exchange channel, the air duct and the storage compartment 3 are sequentially connected and form a circulating air path.

[0045] Referring to Figures 7 to 8 , the air outlet 51 is provided with air guide members, in order to distinguish the air guide members at different positions, the following are distinguished as a first air guide member 52, a second air guide member 53, a third air guide member 54, and a fourth air guide member 55. The air guide members have air guide inclined surfaces facing the air outlet 51, and the air sent out at the air outlet 51 is along the air guide inclined surfaces.

[0046] Specifically, the air outlet 51 is provided with the first air guide member 52 at one end close to the opening of the storage compartment 3, and the included angle a between the air guide inclined surface of the first air guide member 52 and the first direction is an acute angle, wherein the first direction is the opposite direction of the opening direction of the storage compartment 3, that is, the first direction is opposite to the opening direction of the storage compartment 3.

[0047] By providing air guide members at the air outlet 51, the air outlet direction of the uniform temperature module 5 can be controlled, and by setting the angle of the first air guide member 52, the air outlet direction of the uniform temperature module 5 can be controlled, that is, the cold air is blown to the area of the storage compartment 3 where the cold quantity is insufficient, so as to reduce the temperature of the area of the storage compartment 3 far away from the inner container 11, and also to avoid the air outlet of the uniform temperature module 5 directly blowing to the door body 2, thereby reducing the heat exchange between the cold quantity sent out by the air outlet 51 and the door body 2, achieving the effects of energy saving and preventing the door body 2 from condensation.

[0048] Referring to Figures 5 to 7 , further, the refrigeration equipment 100 further comprises a basket 7 arranged in the storage compartment 3, the basket 7 is located between the uniform temperature module 5 and the inner container 11, the basket 7 has an opening, and the opening of the basket 7 faces the opening of the storage compartment 3, that is, the opening of the basket 7 faces the door body 2, and the plane where the air guide inclined surface of the first air guide member 52 is located intersects with the opening of the basket 7. In this way, in the case that the basket 7 is placed in the refrigeration equipment 100, it can be ensured that the cold quantity sent out by the air outlet 51 directly blows to the basket 7, so as to cool and refrigerate the articles stored in the basket 7.

[0049] The number of the basket 7 here can be set according to the space of the storage compartment 3, the size of the basket 7, and the number of the articles stored, and can be one, two or more. Usually, the openings of two or more baskets 7 are coplanar, and if there are two or more baskets 7 and the openings of the baskets 7 are not coplanar, the opening of the basket 7 closest to the opening of the storage compartment 3 is taken as the opening of the basket 7 in the present application.

[0050] Referring to Figure 1 , further, the inner container 11 comprises a first wall 111 extending along a second direction perpendicular to the first direction, and the air return member 6 is arranged on the first wall 111.

[0051] Specifically, the first wall 111 is provided with a pair of first walls 111, and the pair of first walls 111 are oppositely arranged along a third direction, and the third direction is perpendicular to the first direction and the second direction. Correspondingly, the air return member 6 is also provided with a pair of air return members 6, and the pair of air return members 6 are respectively arranged on the pair of first walls 111, and the both ends of the uniform temperature module 5 along the third direction are respectively connected with the pair of air return members 6.

[0052] In addition, the inner container 11 further includes a pair of second walls 112 oppositely arranged along the second direction, each first wall 111 is connected with a pair of second walls 112, and each second wall 112 is connected with a pair of first walls 111. The inner container 11 further includes a third wall 113 oppositely arranged with the opening of the storage compartment 3, and the four edges of the third wall 113 are respectively connected with the pair of first walls 111 and the pair of second walls 112, so that the third wall 113, the pair of first walls 111 and the pair of second walls 112 jointly enclose the storage compartment 3.

[0053] Preferably, the pair of air return members 6 are oppositely arranged along the third direction, the both ends of the uniform temperature module 5 along the third direction are respectively connected with the pair of air return members 6, and the air outlet 51 of the uniform temperature module 5 faces the second wall 112, that is, the uniform temperature module 5 blows air towards the second wall 112.

[0054] Further, the intersection line between the plane where the air guide inclined surface of the first air guide member 52 is located and the second wall 112 is located on the side of the plane where the opening of the basket 7 is away from the opening of the storage compartment 3, so that the cold quantity sent out by the air outlet 51 can be prevented from being blown to the upper part of the basket 7 and gathered at the door body 2, which not only cannot effectively cool the stored articles in the basket 7, but also causes a large amount of cold quantity to flow to the door body 2, resulting in loss of cold quantity and occurrence of condensation of the door body 2.

[0055] Preferably, the size of the first wall 111 along the second direction is greater than the size of the second wall 112 along the second direction, which is more conducive to improving the uniformity of the temperature in the storage compartment 3.

[0056] Preferably, the uniform temperature module 5 is perpendicular to the first wall 111, that is, the uniform temperature module 5 extends along the plane formed by the first direction and the second direction, and the uniform temperature module 5 is located in the middle part of the storage compartment 3, and more preferably, the uniform temperature module 5 passes through the middle line of the pair of first walls 111 along the first direction. In this way, the temperature uniformity in the entire storage compartment 3 can be further improved.

[0057] Referring to Figure 8Preferably, the included angle a between the air guide slope of the first air guide 52 and the first direction is 48°-65°, more preferably 48°-52°. Limiting a in this angle range can, in the case of expanding the air outlet coverage area of the air outlet 51, avoid the case that the cold quantity sent out by the air outlet 51 blows to the door body 2, resulting in a large cold quantity loss and condensation of the door body 2, so as to achieve the effects of energy saving and condensation prevention.

[0058] Further, referring to Figure 5 In the case that 6 baskets 7 are arranged side by side in the second direction in the storage compartment 3 and the baskets 7 store articles, i.e., the baskets 7 are filled with loads, simulation tests are carried out according to GB / T 21001.2-2015, Part 2: Classification, Requirements and Test Conditions for Refrigerated Display Cabinets, and through Figures 9 to 11 It can be seen that, compared with Figure 9 In the case that a is 85° in the prior art, Figure 10 , Figure 11 In the case that a is 48° and 65° in the present application, the cold quantity flow lines between the baskets 7 and the door body 2 can be obviously reduced, i.e., the cold quantity distribution between the baskets 7 and the door body 2 is obviously reduced. When a is in the range of 48°-65°, the cold quantity can flow in the direction away from the door body 2 along the gaps between the baskets 7, so as to increase the contact area between the cold quantity discharged by the air outlet 51 and the articles in the baskets 7, realize effective cooling of the articles in the baskets 7, and improve the temperature uniformity in the entire storage compartment 3.

[0059] Preferably, the air outlet 51 comprises a first air outlet 511 and a second air outlet 512 arranged in the first direction and spaced from the first air outlet 511, and the first air guide 52 is located at one end of the first air outlet 511 away from the second air outlet 512, so as to increase the area of the air outlet 51 and the air outlet coverage area.

[0060] Further, the second air outlet 512 has a second air guide 53 close to the first air outlet 511, and the included angle β between the air guide slope of the second air guide 53 and the first direction is 50°-65°, more preferably 51°-55°. Limiting β in this angle range can, in the case of expanding the air outlet coverage area of the air outlet 51, on the one hand, avoid the case that the cold quantity sent out by the air outlet 51 blows to the door body 2, resulting in a large cold quantity loss and condensation of the door body 2, and on the other hand, avoid the case that the cold quantity sent out by the second air outlet 512 directly returns to the heat exchange channel of the return air guide 6 from the area close to the uniform temperature module 5, resulting in a shortened circulating air path of the cold quantity sent out by the second air outlet 512 in the storage compartment 3 and failing to achieve the effective uniform temperature purpose.

[0061] In a preferred embodiment, β>a is set, so as to expand the air outlet coverage area of the entire air outlet 51; of course, in other embodiments, β=a can also be set, so as to simplify the processing procedure and save production cost.

[0062] More preferably, β-α≤10°. In this way, the air gap between the first air outlet 511 and the second air outlet 512 is avoided, so that the area between the first air outlet 511 and the second air outlet 512 cannot be effectively cooled.

[0063] Further, the first air outlet 511 further has a third air guide 54 close to the second air outlet 512, the first air guide 52 and the third air guide 54 are oppositely arranged along the first direction, the angle between the air guide slope of the third air guide 54 and the first direction is γ, and γ≤α. In this way, the air outlet coverage area of the first air outlet 511 can be ensured, especially when γ<α, that is, the first air outlet 511 is gradually expanded, so that the air outlet coverage area of the first air outlet 511 can be expanded.

[0064] Further, the second air outlet 512 further has a fourth air guide 55 away from the first air outlet 511, the second air guide 53 and the fourth air guide 55 are oppositely arranged along the first direction, the angle between the air guide slope of the fourth air guide 55 and the first direction is μ, and μ≤β. In this way, the air outlet coverage area of the second air outlet 512 can be ensured, especially when γ<α, that is, the second air outlet 512 is gradually expanded, so that the air outlet coverage area of the second air outlet 512 can be expanded.

[0065] Specifically, the first air outlet 511 can be provided with one or at least two, and the second air outlet 512 is the same, so that the air outlet area of the air outlet 51 can be increased, the air outlet coverage area can be expanded, and the temperature uniformity in the storage compartment 3 can be further improved.

[0066] Preferably, the at least two first air outlets 511 are spaced apart along the third direction. Preferably, the at least two second air outlets 512 are spaced apart along the third direction. In this way, the air outlet 51 can be arranged at a better position to better improve the temperature distribution in the storage compartment 3.

[0067] Preferably, the first air outlet 511 can be provided in a strip shape, and the second air outlet 512 is the same, so that the air outlet area of the air outlet 51 can be increased, the air outlet coverage area can be expanded, and the temperature uniformity in the storage compartment 3 can be further improved.

[0068] Further, the ratio of the size of the heat exchange channel to the size of the first wall 111 in the second direction is 1 / 6-2 / 3. In this size ratio, the size ratio of the heat exchange channel and the first wall 111 can enhance the temperature equalization effect of the temperature equalization module 5, while the cost can be controlled. When the size ratio is <1 / 6, the cold quantity sent out from the air outlet 51 of the temperature equalization module 5 will mainly return to the air return part 6 along the temperature equalization module 5, and such a circulating air path is shorter, and the temperature equalization effect on the area in the storage compartment 3 far away from the inner container 11 and the temperature equalization module 5 is poor, and the temperature uniformity in the storage compartment 3 is poor. When the size ratio is >2 / 3, the cost of raw materials and installation is greatly increased, which is not conducive to cost control.

[0069] Preferably, the air return part 6 extends in the second direction, and the heat exchange channel also extends in the second direction, so that the material can be saved, the installation process can be simplified, and the cost can be reduced while ensuring the temperature equalization effect.

[0070] Further, the heat exchange channel includes a pair of sub-channels in communication with each other, and the pair of sub-channels are respectively located on both sides of the temperature equalization module 5. Among them, the air outlet 51 of the temperature equalization module 5 is provided with two, and the two air outlets 51 are oppositely arranged at the two ends of the temperature equalization module 5 in the second direction.

[0071] For ease of description, hereinafter, the sub-channel on one side of the temperature equalization module 5 and the air outlet 51 on the side corresponding to the sub-channel are taken as examples for description. The sub-channel has an upper edge close to the opening of the storage compartment 3 and a lower edge away from the opening of the storage compartment 3, and the end of the air outlet 51 away from the opening of the storage compartment 3 is provided with a wind guide part, which refers to the fourth wind guide part 55 in the foregoing, and the line connecting the midpoint of the upper edge and the midpoint of the lower edge intersects the plane in which the wind guide slope of the fourth wind guide part 55 is located.

[0072] In this way, the temperature drop of the area in the storage compartment 3 far away from the inner container 11 can be ensured, and the overall temperature uniformity in the storage compartment 3 can be improved.

[0073] Further, the plane in which the wind guide slope of the fourth wind guide part 55 is located intersects the opening of the basket 7. In this way, the cold quantity sent out from the air outlet 51 can be directly blown to the basket 7, so that the items stored in the basket 7 can be effectively cooled, and the cold quantity sent out from the air outlet 51 can be prevented from directly returning to the heat exchange channel of the air return part 6 from the gap between the basket 7 and the temperature equalization module 5, so that the circulating air path of the cold quantity sent out from the air outlet 51 in the storage compartment 3 is shortened and cannot achieve the purpose of effective temperature equalization.

[0074] Referring to Figure 5 and Figure 7Further, the air return member 6 is provided with an air return opening 61, and the distance between the air return opening 61 and the third wall 113 is 10-40 cm. Since the evaporation pipe 4 is wound on the inner container 11, and the cold air has a tendency to sink, the area with the lowest temperature in the inner container 11 is usually the area close to the third wall 113. By setting the distance between the air return opening 61 and the third wall 113 to be 10-40 cm, on the one hand, the heat exchange efficiency of the heat exchange channel in the air return member 6 and the inner container 11 can be improved, thereby improving the temperature equalization effect of the temperature equalization module 5, and on the other hand, space is reserved for the installation of the air return member 6, and the mutual interference between the air return member 6 and the basket 7 can be avoided.

[0075] Referring to Figure 7 Specifically, the air return member 6 includes a cover plate 62 and a pair of first side plates 63, the cover plate 62 is parallel to the first wall 111, the first side plates 63 extend along the first direction, the pair of first side plates 63 are oppositely arranged along the second direction, and the first side plates 63 connect the cover plate 62 and the first wall 111. The air return opening 61 includes a first air return opening 611 provided on the first side plate 63, and the distance between the first air return opening 611 and the third wall 113 is 10-40 cm. By providing the first air return opening 611 on the first side plate 63, the situation that the first air return opening 611 is blocked by the articles stored in the storage compartment 3 and cannot return air can be avoided.

[0076] Further, the air return member 6 further includes a second side plate 64, the second side plate 64 is arranged at one end of the cover plate 62 close to the third wall 113, and the second side plate 64 connects the cover plate 62 and the first wall 111. The air return opening 61 includes a second air return opening 612 provided on the second side plate 64, and the distance between the second air return opening 612 and the third wall 113 is 10-40 cm. By providing the second air return opening 612 on the second side plate 64, the situation that the second air return opening 612 is blocked by the articles stored in the storage compartment 3 and cannot return air can be avoided.

[0077] Further, the distance between the end of the air return member 6 away from the third wall 113 and the third wall 113 is ≤40 cm, which can effectively prevent the mutual interference between the air return member 6 and the basket 7.

[0078] In the embodiment, the air return member 6 is detachably mounted and fixed on the shell 12. By setting the air return member 6 to be detachably mounted on the shell 12, the air return member 6 can be replaced conveniently.

[0079] Referring to Figure 7 In the embodiment, the end of the shell 12 of the temperature equalization module 5 towards the third wall 113 has a gap part 8 with the third wall 113. On the one hand, the cold energy on both sides of the temperature equalization module 5 can exchange and flow from the gap part 8, thereby improving the uniformity of the temperature in the storage compartment 3. On the other hand, the air return member 6 can be installed and connected with the temperature equalization module 5 from the gap part 8.

[0080] Further, the air inlet of the air duct is arranged on the shell 12, the air outlet of the heat exchange channel is arranged on the cover plate 62, and the air outlet is in communication with the air inlet. The uniform temperature module 5 further comprises a fan assembly 56 arranged in the air duct, and the fan assembly 56 is used to drive the cold energy to flow from the air inlet to the air outlet 51. The fan assembly 56 comprises a fan.

[0081] In summary, the refrigeration equipment 100 of the present application can transmit the cold energy generated by the evaporation pipe 4 to the area close to the opening of the storage compartment 3 through the heat exchange channel in the return air piece 6 and the air duct in the uniform temperature module 5, thereby improving the uniformity of the cold energy distribution in the storage compartment 3. By arranging the air guide piece at the air outlet 51, the air outlet direction of the uniform temperature module 5 can be controlled. By adjusting the angle of the first air guide piece 52, the air outlet of the uniform temperature module 5 can be controlled to be downward, i.e. towards the area with insufficient cold energy in the storage compartment 3, thereby reducing the temperature of the area far away from the inner container 11 in the storage compartment 3, and avoiding the air outlet of the uniform temperature module 5 directly blowing on the door body 2, reducing the heat exchange between the cold energy blown out of the air outlet 51 and the door body 2, achieving the effects of energy saving and preventing the door body 2 from condensation.

The above description is only the preferred embodiments of the present application, but the present application is not limited to the embodiments shown in the drawings. Any changes or modifications made according to the concept of the present application, or equivalent embodiments with equivalent changes, shall be within the scope of the present application.
