[0057] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the various specific processes and material examples provided by the present application, but those of ordinary skill in the art can appreciate the application of other processes and / or the use of other materials.

[0058] The refrigeration equipment in the present application generally includes a cabinet, a door and a refrigeration system, wherein at least a refrigeration compartment is formed in the cabinet, and the refrigeration compartment is opened and closed through the door to meet the requirements of storing and retrieving items.

[0059] The refrigeration system uses a compressor, condenser, expansion valve and evaporator to perform the refrigeration cycle of the refrigeration equipment. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to achieve cooling of the items in the cabinet.

[0060] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0061] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can cool the items in the cabinet by utilizing the latent heat of evaporation of the refrigerant.

[0062] like Figure 1-Figure 12 As shown, an embodiment of the present application provides a refrigeration device, including: a cabinet body 1 and a sliding door assembly 2.

[0063] A storage room 11 is formed in the cabinet body 1 , and a cabinet opening 12 is provided on the top of the cabinet body 1 . The cabinet opening 12 surrounds the top of the storage room 11 to form a receiving and placing opening 13 for taking and placing articles.

[0064] Specifically, a storage chamber 11 is formed inside the cabinet 1, and items that need to be refrigerated or frozen can be placed in the storage chamber 11 for refrigerated storage. The cabinet opening 12 of the cabinet 1 forms a take-in and put-out opening 13 at the top of the storage chamber 11, and the user can put items into the storage chamber 11 or take items out of the storage chamber 11 through the take-in and put-out opening 13.

[0065] Correspondingly, a machine compartment can also be set in the cabinet 1, and components such as a compressor and a condenser can be installed in the machine compartment. The refrigeration method in the cabinet 1 can be direct cooling or air cooling. The specific refrigeration method of the refrigeration equipment in this embodiment is not limited or elaborated here.

[0066] The sliding door assembly 2 includes a first glass door 21 and a second glass door 22 , and the first glass door 21 and the second glass door 22 can slide relative to each other.

[0067] Specifically, the sliding door assembly 2 includes a first glass door 21 and a second glass door 22 that can slide relative to each other. The first glass door 21 and the second glass door 22 can both slide on the cabinet opening 12. On the one hand, the access opening 13 can be opened or closed by the first glass door 21 and the second glass door 22. On the other hand, the user can observe the storage status of items in the storage room 11 through the first glass door 21 and the second glass door 22, so as to facilitate the user to intuitively store and retrieve items.

[0068] Among them, since the cabinet body 1 adopts foaming to carry out insulation treatment, the cabinet body 1 has certain requirements on the thickness of the foam. Correspondingly, in order to meet the installation requirements of the first glass door 21 and the second glass door 22, it is also necessary to additionally set an installation area on the cabinet opening 12 of the cabinet body 1 to install the first glass door 21 and the second glass door 22. To this end, while meeting the installation requirements of the first glass door 21 and the second glass door 22 and further meeting the thermal insulation performance of the cabinet body 1, the thickness of the cabinet body 1 is reduced as much as possible, and the following improvements are made to the installation method of the first glass door 21 and the second glass door 22.

[0069] In order to reduce the space of the storage room 11 in the cabinet body 1 required for installing the first glass door 21 and the second glass door 22, a sliding support surface 121 is respectively provided on both sides of the cabinet opening 12. That is, only a single sliding support surface 121 is provided on both sides of the cabinet opening 12 to simultaneously install the first glass door 21 and the second glass door 22.

[0070] A first sliding support portion 211 is respectively provided on both sides of the first glass door 21, the first sliding support portion 211 extends downward, and the first sliding support portion 211 is slidably arranged on the sliding support surface 121 on the corresponding side. The second glass door 22 is located between the two first sliding support portions 211, and the side portion of the second glass door 22 is slidably arranged on the sliding support surface 121 on the corresponding side; the vertical projection of the first sliding support portion 211 is located within the sliding support surface 121, and the distance between the inner edges of the two sliding support surfaces 121 is less than the width of the second glass door 22.

[0071] Specifically, during the assembly process, the two side portions of the first glass door 21 and the two side portions of the second glass door 22 are respectively overlapped on the sliding support surfaces 121 on the corresponding sides, so that the two glass doors can share one sliding support surface 121 to meet the installation requirements of the sliding support on the corresponding sides.

[0072] Since there is no need to configure independent sliding support surfaces 121 for the first glass door 21 and the second glass door 22 respectively, compared with the cabinet opening 12 in the prior art, in which a corresponding step surface is configured on the corresponding side of the cabinet opening 12 for each layer of glass door, the width of each step surface needs to meet the sliding installation requirements of the glass door on the corresponding side, which results in a reduction in storage volume and an increase in the thickness of the cabinet body 1.

[0073] The present application adopts a single-layer sliding support surface 121 to simultaneously install the first glass door 21 and the second glass door 22, and thus it is not necessary to form a multi-layer step surface arranged up and down on the inner side of the cabinet opening 12 to install the glass door. In this way, the storage volume of the storage room 11 in the cabinet body 1 can be reduced due to the arrangement of the multi-layer sliding support surface 121 on the side of the cabinet opening 12.

[0074] At the same time, single-layer sliding support surfaces 121 are formed on both sides of the cabinet opening 12, which can effectively reduce the wall thickness of the cabinet body 1, thereby reducing the amount of foaming material used, further reducing the manufacturing cost.

[0075] The width of the sliding support surface 121 needs to be designed to meet the installation requirements of the first glass door 21 and the second glass door 22 at the same time. Specifically, since the first glass door 21 slides above the second glass door 22, the first sliding support portion 211 formed on the first glass door 21 needs to always contact the sliding support surface 121. To this end, the projection of the first sliding support portion 211 on the surface perpendicular to the sliding support surface 121 will be located within the sliding support surface 121 to ensure that the first sliding support portion 211 can always obtain the support of the sliding support surface 121.

[0076] For the second glass door 22, the second glass door 22 will be located between the two first sliding support parts 211 and slide on the sliding support surface 121. In order to meet the requirement of reliable sliding of the second glass door 22, the second glass door 22 also needs to have an overall width dimension greater than the distance between the inner edges of the two sliding support surfaces 121, thereby ensuring that the second glass door 22 will not fall off during the sliding process on the sliding support surface 121.

[0077] By adopting the above design, the first glass door 21 and the second glass door 22 can be installed on the same sliding support surface 121 on the same side, thereby reducing the wall thickness of the cabinet 1 of the refrigeration equipment and reducing the amount of foaming material used, thereby increasing the effective volume of the cabinet 1 and reducing manufacturing costs.

[0078] In an embodiment of the present application, an annular step structure 122 is provided on the inner side of the cabinet opening 12 , and the step surfaces of the annular step structure 122 distributed on both sides of the cabinet opening 12 respectively form the sliding support surfaces 121 .

[0079] Specifically, for the cabinet opening 12 , in order to form the sliding support surface 121 , an annular step structure 122 is formed on the inner side of the cabinet opening 12 , and the step surface formed by the annular step structure 122 distributed on both sides of the cabinet opening 12 constitutes the sliding support surface 121 on the corresponding side.

[0080] In another embodiment, since a single-layer sliding support surface 121 is used on the same side of the cabinet opening 12 to support and install the first glass door 21 and the second glass door 22, in order to improve the structural strength of the portion where the annular step structure 122 forms the sliding support surface 121, a structural reinforcement is provided on the lower surface of the annular step structure 122, and the structural reinforcement is provided below each of the sliding support surfaces 121;

[0081] The structural reinforcement member includes a first reinforcement rib 123 and a second reinforcement rib 124 , wherein the first reinforcement rib 123 extends along the length direction of the sliding support surface 121 , and the extension direction of the second reinforcement rib 124 is staggered with the extension direction of the first reinforcement rib 123 .

[0082] Specifically, a structural reinforcement is formed on the lower surface of the annular step structure 122, and the structural reinforcement includes a first reinforcement rib 123 and a second reinforcement rib 124 that are cross-arranged. The first reinforcement rib 123 and the second reinforcement rib 124 are then used to enhance the overall structural strength of the annular step structure 122 where the sliding support surface 121 is formed, so as to improve the reliability of the cabinet opening 12.

[0083] In another embodiment of the present application, the first glass door 21 includes a first frame 212 and a first glass plate 213, the first sliding support parts 211 are respectively disposed on both sides of the first frame 212, and the first glass plate 213 is disposed in the first frame 212;

[0084] The second glass door 22 includes a second frame body 222 and a second glass plate 223 , and the second glass plate 223 is disposed in the second frame body 222 .

[0085] Specifically, the first frame 212 can be processed by injection molding, the first frame 212 is wrapped around the periphery of the first glass plate 213, and the first frame 212 itself forms the first sliding support part 211 on both sides. Similarly, the second frame 222 can be processed by injection molding, the second frame 222 is wrapped around the periphery of the second glass plate 223, and the second frame 222 is overlapped on the sliding support surface 121 to meet the sliding requirements.

[0086] In one embodiment, the second frame body 222 is provided with second sliding support parts 221 on both sides thereof, the second sliding support parts 221 extend downward, and the second sliding support parts 221 are slidably disposed on the sliding support surface 121 on the corresponding side;

[0087] The first sliding support portion 211 is arranged on the outer side of the second sliding support portion 221 on the corresponding side.

[0088] Specifically, in order to reduce the friction between the second glass door 22 and the sliding support surface 121 and improve the sliding smoothness of the second glass door 22, the second glass door 22 is provided with second sliding support parts 221 on both sides of the second frame 222, and then supported to slide on the sliding support surface 121 by the second sliding support parts 221.

[0089] At the same time, in order to ensure that the first glass door 21 and the second glass door 22 are installed on the same sliding support surface 121, the second sliding support parts 221 on both sides of the second glass door 22 are located between the two first sliding support parts 211, ensuring that the first glass door 21 and the second glass door 22 can slide relative to each other on the same sliding support surface 121 without affecting each other.

[0090] In some embodiments, the first sliding support part 211 may be a continuous strip structure or a strip structure arranged at intervals. The first sliding support part 211 is distributed on the outer side of the second glass door 22, and plays a role of supporting the sliding on the one hand, and guiding the sliding of the second glass door 22 on the other hand. The second sliding support part 221 may be a strip structure, or the second sliding support part 221 may be a columnar structure. There is no limitation on the first sliding support part 211 and the second sliding support part 221.

[0091] In one embodiment of the present application, outwardly extending protrusions 224 are further provided on both sides of the end of the second frame 222 away from the first frame 212 , and the protrusions 224 are configured to cooperate with the inner wall of the cabinet opening 12 to guide the second frame 222 to slide on the sliding support surface 121 .

[0092] Specifically, for the second glass door 22, one end of the second glass door 22 will be located between the two first sliding support parts 211 and covered by the first glass door 21. During the sliding process, the end of the second glass door 22 will be guided by the first sliding support parts 211 on both sides to slide. The other end of the second glass door 22 is arranged outside the first glass door 21. During the sliding process, the other end of the second glass door 22 will be guided by the protrusions 224 on both sides to cooperate with the inner side wall of the cabinet opening 12 to slide, so as to improve the sliding smoothness of the second glass door 22.

[0093] In some embodiments, in order to facilitate the user to push and pull the first glass door 21 and the second glass door 22 during use, a first handle portion 214 is provided on the upper surface of the end of the first frame body 212 away from the second frame body 222, and a second handle portion 225 is provided on the upper surface of the end of the second frame body 222 away from the first frame body 212.

[0094] Specifically, taking the first frame 212 as an example, a first handle portion 214 will be formed on the first frame 212 during the processing, and the first handle portion 214 can be a protruding structure or a recessed structure to meet the user's manual pushing and pulling requirements.

[0095] In one embodiment of the present application, the refrigeration device further includes a storage basket 3;

[0096] A storage space is formed in the storage basket 3, and two sides of the storage basket 3 are respectively provided with overlapping parts 31 extending outwards;

[0097] The sliding support surface 121 is provided with an overlapping groove 125 , and the overlapping portion 31 is located in the overlapping groove 125 on the corresponding side.

[0098] Specifically, in order to fully utilize the space in the storage room 11 and meet the requirements of storing different items separately, a storage basket 3 can be placed in the storage room 11, and the storage basket 3 will overlap the cabinet opening 12 with the overlapping parts 31 on both sides. Similarly, in order to fully utilize the sliding support surfaces 121 formed on both sides of the cabinet opening 12 to install the storage basket 3, overlapping grooves 125 can be formed on the sliding support surfaces 121 to overlap with the overlapping parts 31 of the storage basket 3. In this way, there is no need to set an additional step structure on the cabinet opening 12 for the storage basket 3 to meet the installation requirements, which is more conducive to meeting the design of thin wall thickness of the cabinet body 1.

[0099] In some embodiments, in order to improve the reliability of the overlapping of the storage basket 3, a notch 126 is formed on the inner edge of the annular step structure 122, and the two ends of the overlapping groove 125 are respectively connected to the notches 126 at the corresponding ends. In addition, a blocking portion 127 is formed on the inner side of the overlapping groove 125 on the annular step structure 122, and the upper surface of the blocking portion 127 is not higher than the sliding support surface 121.

[0100] For the storage basket 3, the overlapping portion 31 is usually a U-shaped frame structure.
