DETAILED DESCRIPTION

[0055] The technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0056] In the description of the present application, it should be understood that the terms "center", "transverse", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0057] The terms "first", "second", "third", are used only for descriptive purposes and should not be construed as implying or suggesting relative importance or an indicated number of the technical features indicated. Thus, the features defined with "first", "second", "third" can explicitly or implicitly include one or more of the features.

[0058] In the description of the utility model, it needs to explain, unless another explicit stipulation and limitation, the term "installation", "linkage", "connection" should do the broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be direct connection, also can be indirect connection through the intermediate medium, can be the intercommunication of two elements inside. For ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according of the specific circumstances.

[0059] The utility model provides a kind of freezer showcase 100, it is related to refrigeration equipment technical field, below reference Figures 1 to 14 Freezer showcase 100 is described.

[0060] Please refer to Figure 1 In the illustrative embodiment of the utility model freezer showcase 100, the freezer showcase 100 can include cabinet 1 and cabinet mouth 2.

[0061] The inside of cabinet 1 is defined with storage cavity 11, and the storage cavity 11 is used to place, store food and other articles that need to be frozen in a low-temperature environment.

[0062] Among them, cabinet 1 is substantially hollow cuboid shape, and cabinet 1 forms the main structure of freezer showcase 100. The cuboid-shaped cabinet 1 is simple and elegant, and can better adapt to the space layout of most commercial places, facilitating installation and placement.

[0063] Cabinet mouth 2 is provided on the top of cabinet 1, and cabinet mouth 2 is provided with an opening 24 communicating with the storage cavity 11. Through the opening 24 of the cabinet mouth 2, the user can conveniently take and place articles from the storage cavity 11.

[0064] It can be understood that the cabinet 1 can include a shell, and the shell has an installation space inside.

[0065] The cabinet 1 can include an inner container connected to the inside of the shell. That is, the inner container is disposed in the installation space. The inner container and the shell form a foaming space therebetween, and the foaming space is provided with a foaming layer to achieve heat preservation and insulation of the cabinet 1.

[0066] Among them, the foaming space is used to inject foaming material so as to foam the cabinet 1, so that the inner container and the shell have a foaming layer therebetween.

[0067] It can be understood that the foaming layer plays a role of heat insulation to reduce the heat transfer between the inside of the horizontal refrigeration display cabinet 100 and the outside, thereby improving the heat insulation effect of the storage cavity 11.

[0068] In this embodiment, the thickness of the foaming layer can be 80mm. The use of a thicker foaming layer can significantly reduce the loss of cold air, improve the heat preservation performance of the cabinet body 1, reduce energy consumption, and effectively achieve energy saving effect.

[0069] In some embodiments, the refrigeration display cabinet 100 can include a sliding door for opening or closing the opening 24. The sliding door is provided to facilitate users to quickly take or place the goods.

[0070] Referring to Figure 2 , opposite sides of the cabinet opening 2 are provided with slide structures 5, and the sliding door is slidably arranged on the slide structures 5. The slide structures 5 can provide stable support for the sliding door, and the sliding stability of the sliding door is improved by providing the slide structures 5.

[0071] Specifically, referring to Figure 1 , the sliding door can include a lower door body 4 and an upper door body 3. The upper door body 3 and the lower door body 4 have a height difference in the vertical direction, so that the upper door body 3 and the lower door body 4 do not affect each other when sliding. The upper door body 3 and the lower door body 4 can be slid to a position of coincidence.

[0072] In this embodiment, the opening 24 is closed or opened by the cooperation of the upper door body 3 and the lower door body 4. When it is necessary to take or place goods through the opening 24, the upper door body 3 or the lower door body 4 can be selectively slid to open part of the area of the opening 24, thereby reducing the heat exchange area of the opening 24 with the outside, reducing the leakage of cold energy, and saving energy and protecting the environment.

[0073] Further, the upper door body 3 and the lower door body 4 are both hollow glass doors.

[0074] The hollow glass door has good transparency. The use of the hollow glass door for the upper door body 3 and the lower door body 4 not only ensures the good display effect of the refrigeration display cabinet 100, but also reduces heat transfer and improves the heat preservation performance of the cabinet body 1 by the heat insulation performance of the hollow glass structure, thereby reducing energy consumption.

[0075] In the related art, the conventional cooperation mode of the cabinet opening 2 and the door body is that the door body is sunken into the inside of the cabinet opening 2. The overall thickness of the hollow glass door is much larger than that of the traditional door body. When the conventional cooperation mode of the cabinet opening 2 and the door body is used to install the thicker hollow glass door, the height of the cabinet opening 2 needs to be increased. The too high cabinet opening 2 not only affects the loading quantity of the refrigeration display cabinet 100, but also reduces the overall aesthetics and display effect of the display cabinet.

[0076] In addition, in the related art, the upper door body 3 and the lower door body 4 are both sunken into the cabinet opening 2, and a narrow gap is formed between the end of the sliding door and the cabinet opening 2. When the user pushes or pulls the door body, the fingers are easy to enter the gap and be pinched.

[0077] In order to maximize the utilization rate of the space inside the cabinet body 1, in the embodiment, the upper door body 3 is lifted at the position of the cabinet opening 2, so that the height of the upper door body 3 is higher than the top end of the opening 24 of the cabinet opening 2. This setting reduces the height occupation of the cabinet opening 2, thereby increasing the available space inside the cabinet body 1 and improving the space utilization rate. Figure 2 , Figure 3

[0078] Referring to Figure 5 , Figure 7 A slot 31 extending along the sliding direction of the upper door body 3 is arranged at each end of the upper door body 3, and the slot 31 provides a limiting space for the upper door body 3.

[0079] Further, referring to Figure 4 , Figure 6 The cabinet opening 2 can include a top plate 21 located above the slide structure 5 on at least one side. The at least one top plate 21 is accommodated in the corresponding slot 31 to limit the up-down movement of the upper door body 3.

[0080] In the embodiment, the slot 31 and the top plate 21 cooperate to accurately limit the up-down movement range of the upper door body 3, meet the limiting requirement of the upper door body 3, reduce the risk of derailment, and ensure that the door body remains stable during the sliding process. At the same time, by hiding the free end of the top plate 21 in the slot, the end of the upper door body 3 and the potential pinching space are eliminated, and the possibility of finger pinching is fundamentally avoided.

[0081] Further, by setting the upper door body 3 to be higher than the top end of the opening 24, i.e., the upper door body 3 is higher than the surface of the cabinet opening 2 where the top end of the opening 24 is located, the cooperation relationship between the upper door body 3 and the cabinet opening 2 is optimized, and a certain physical space isolation is formed. During the process of pushing or pulling the upper door body 3, the hand and the cabinet opening 2 always maintain a certain space distance, effectively avoiding the hand being pinched between the end of the upper door body 3 and the cabinet opening 2, reducing the risk of hand pinching, and improving the safety.

[0082] Although the hollow glass door has good heat insulation performance, due to its large weight, a large force is required to push or pull the door body, and it is difficult to simultaneously meet the smoothness and sealing requirements of the door body, resulting in poor user experience.

[0083] In order to solve the above technical problems, in some embodiments of the present application, the opposite two end sides of the hollow glass door are provided with sliding strips, so that the end sides of the hollow glass door are connected with the slide structure 5 through the sliding strips. ​

[0084] The sliding strip on the end side of the hollow glass door not only reduces the friction between the hollow glass door and the slide structure 5, but also effectively improves the sealing between the door body and the cabinet opening 2, and improves the heat preservation performance.

[0085] Further, the bottom side of the hollow glass door is provided with a sliding strip or a pulley, so that the bottom side of the hollow glass door is connected with the slide structure 5 through the sliding strip or the pulley.

[0086] In this embodiment, the user can select a sliding strip or a pulley according to actual needs. The sliding strip provides better sealing, and the pulley provides a smoother sliding experience, meeting the needs of different scenes.

[0087] In some embodiments of the present application, with reference to Figure 6 , the slide structure 5 can include a first step portion 51 and a second step portion 52, and the first step portion 51 and the second step portion 52 have a height difference in the height direction of the machine body.

[0088] By setting the first step portion 51 and the second step portion 52 with different heights, the upper door body 3 and the lower door body 4 can be independently slid at different height levels without interfering with each other.

[0089] Among them, with reference to Figure 4 , the upper door body 3 is in sliding connection with the first step portion 51. The lower door body 4 is in sliding connection with the second step portion 52. The sliding connection can ensure that the upper door body 3 and the lower door body 4 are smoother during sliding, reduce jamming, and improve user experience.

[0090] Specifically, with reference to Figure 7 , Figure 11 , the end side of the upper door body 3 is provided with a first sliding strip 61, and the side of the first sliding strip 61 away from the upper door body 3 is in sliding connection with the side wall of the first step portion 51.

[0091] Continuing to refer to Figure 11 , the end side of the lower door body 4 is provided with a third sliding strip 63, and the side of the third sliding strip 63 away from the lower door body 4 is in sliding connection with the side wall of the second step portion 52.

[0092] In this embodiment, by setting the first sliding strip 61 and the second sliding strip 62, the friction between the upper door body 3, the lower door body 4 and the slide structure 5 can be reduced, and the sliding of the upper and lower door bodies 4 is smoother, improving the operation performance of the sliding door.

[0093] At the same time, the setting of the first sliding strip 61 and the second sliding strip 62 can also enhance the sealing between the upper door body 3, the lower door body 4 and the slide structure 5, further reduce the leakage of cold air, and improve the energy saving effect of the refrigerated display cabinet 100.

[0094] Further, with reference to Figure 7 ,Figure 9 The bottom side of the upper door body 3 is provided with a second sliding strip 62 or a first pulley assembly 7, so that the second sliding strip 62 is in sliding connection with the supporting surface of the first step portion 51 or the first pulley assembly 7 is in rolling connection with the supporting surface of the first step portion 51.

[0095] The above-mentioned optional connection mode can flexibly select the sliding mode of the upper door body 3 according to different use requirements and scenes, further improving the adaptability and flexibility of the sliding door.

[0096] Referring to Figure 13 When the first pulley assembly 7 is arranged on the bottom side of the upper door body 3, the rolling connection has lower friction than the sliding connection, which can make the sliding of the upper door body 3 more convenient and smooth, further improving the user experience.

[0097] When the second sliding strip 62 is arranged on the bottom side of the upper door body 3, the sliding connection has better sealing performance, which can better meet the use scene with high sealing performance requirement.

[0098] In the embodiment, the bottom side of the upper door body 3 is selectively provided with the second sliding strip 62 or the first pulley assembly 7, which not only effectively solves the problem that the hollow glass door is heavy and difficult to slide, but also can be selected according to different customer requirements for the overall sealing performance and sliding smoothness of the refrigerated display cabinet 100.

[0099] Referring to Figure 12 、 Figure 13 The bottom side of the lower door body 4 is provided with a fourth sliding strip 64 or a second pulley assembly 8, so that the fourth sliding strip 64 is in sliding connection with the supporting surface of the second step portion 52 or the second pulley assembly 8 is in rolling connection with the supporting surface of the second step portion 52. The bottom side of the lower door body 4 is selectively provided with the fourth sliding strip 64 or the second pulley assembly 8, which has the same technical effect as the upper door body 3 selectively provided with the second sliding strip 62 or the first pulley assembly 7, which will not be described in detail.

[0100] In some embodiments of the present application, referring to Figure 14 The cabinet opening 2 can include a front frame 22 and a rear frame 23 which are arranged at intervals along the width direction of the cabinet body 1. The front frame 22 and the rear frame 23 are both provided with a sliding track structure 5.

[0101] The sliding track structure 5 is arranged on the front frame 22 and the rear frame 23, which can provide bilateral support for the sliding door and ensure that the sliding door is more stable during sliding.

[0102] Further, referring to Figure 14 The frame body includes a first end stop assembly 25 and a second end stop assembly 26 which are oppositely arranged. The front frame 22, the first end stop assembly 25, the rear frame 23 and the second end stop assembly 26 are sequentially and end-to-end connected to form the cabinet opening 2.

[0103] Reference Figure 6 、 Figure 14 The top plate 21 is configured to be formed on the rear frame 23, and both ends of the top plate 21 extend to both ends of the length direction of the rear frame 23.

[0104] In this embodiment, both ends of the top plate 21 extend to both ends of the length direction of the rear frame 23, so that the overall appearance of the cabinet opening 2 is more concise, and the aesthetics of the display cabinet is improved. Among them, the projection of the top plate 21 in the vertical direction is located within the projection of the first step portion 51, so as to avoid the top plate 21 affecting the display effect of the refrigerated display cabinet 100.

[0105] The front frame 22 is provided with a limiting portion 9, and the limiting portion 9 is adapted to be inserted into the slot 31 away from the top plate 21. Among them, through the cooperation of the two slots 31 of the upper door body 3, the top plate 21 and the limiting portion 9, the accidental disengagement of the upper door body 3 during the sliding process is further avoided.

[0106] Reference Figure 14 The limiting portion 9 is located in at least part of the region between the middle of the front frame 22 and one end of the length direction of the front frame 22.

[0107] By setting the limiting portion 9 in the region from the middle of the front frame 22 to one end thereof, and not setting the limiting portion 9 in the remaining region, the upper door body 3 can be disassembled upwardly in the remaining region, so as to facilitate the user to quickly disassemble and assemble the upper door body 3 according to the actual needs.

[0108] When the display cabinet needs to store larger volume items inside, or needs to clean the hollow glass door, the user can slide the upper door body 3 to the remaining region where the limiting portion 9 is not set, and remove the upper door body 3 upwardly away from one end of the top plate 21.

[0109] In this embodiment, the second step portion 52 protrudes toward the center of the cabinet 1 relative to the first step portion 51. This setting makes it possible to directly move the lower door body 4 upwardly to achieve the disassembly of the lower door body 4 after the upper door body 3 is removed.

[0110] In some embodiments of the present application, the opening 24 is divided into a first installation region and a second installation region, the upper door body 3 can slidably close or open the first installation region, and the lower door body 4 can slidably close or open the second installation region.

[0111] The user can selectively slide the upper door body 3 or the lower door body 4 when taking or placing the items, so as to selectively open the first installation region or the second installation region, thereby reducing the leakage of cold when taking or placing the items.

[0112] It can be understood that when the sliding door closes the opening 24, the upper door body 3 is used to close the first installation region, and the lower door body 4 is used to close the second installation region.

[0113] In some embodiments, the limiting part 9 is located in the first mounting area. By arranging the limiting part 9 in the first mounting area, when the sliding door closes the opening 24, the limiting part 9 cooperates with the top plate 21 to limit the upward movement of the upper door body 3, avoiding the upper door body 3 from being separated from the cabinet opening 2, and enhancing the sealing performance.

[0114] In some embodiments, the front frame 33 is provided with a clamping groove towards the side wall of the upper door body 3, and the limiting part 9 is adapted to be clamped in the clamping groove, so that the limiting part 9 can be detachably connected to the front frame 22.

[0115] In this embodiment, the limiting part 9 is detachably arranged, so that the refrigerated display cabinet 100 can be flexibly adjusted according to different use scenarios and user needs.

[0116] In actual application, the first end stop assembly 25 and the second end stop assembly 26 may be made of different materials and thicknesses due to different forces. Even in the same assembly, the materials and thicknesses of the parts are not completely the same. Therefore, in order to facilitate production, in some embodiments, the first end stop assembly 25 and the second end stop assembly 26 are split and arranged.

[0117] Reference Figure 15 The first end stop assembly 25 includes a first housing 251 and a second housing 252 which are detachably connected.

[0118] The detachable connection design makes the first housing 251 and the second housing 252 can be produced, packaged and transported respectively, which reduces the production difficulty and transportation cost, and facilitates quick assembly during production and quick replacement of parts during maintenance.

[0119] Reference Figure 6 The first housing 251 is formed with a first connecting table 2511, and the two ends of the first connecting table 2511 are connected with the two first stepped portions 51. The second housing 252 is detachably connected to the bottom end of the first connecting table 2511.

[0120] The first connecting table 2511 can provide support for the bottom of one end of the upper door body 3 when the sliding door closes the opening, ensuring that the upper door body 3 does not jam during the sliding process, improving the comfort and reliability of use, and improving the sealing between the upper door body 3 and the cabinet opening 2.

[0121] In some embodiments, reference Figure 16 The second end stop assembly 26 includes a third housing 261 and a fourth housing 262 which are detachably connected. Reference Figure 14 The third housing 261 is formed with a second connecting table 2611, and the two ends of the second connecting table 2611 are connected with the two second stepped portions 52. The fourth housing 262 is detachably connected to the bottom end of the second connecting table 2611.

[0122] The second connecting platform 2611 can provide support for the bottom of one end of the lower door body 4 when the sliding door closes the opening, ensuring that the lower door body 4 does not jam during sliding, improving the comfort and reliability of use, and improving the sealing between the lower door body 4 and the cabinet opening 2.

[0123] In this embodiment, the first end stop assembly 25 and the second end stop assembly 26 are split and arranged, which is convenient for production, packaging and transportation. At the same time, each component after splitting can need to choose different colors and materials, which is beneficial to improve the appearance.

[0124] Specifically, due to the complex structure of the cabinet opening 2, there will be corner positions that are difficult to further process during production, affecting production efficiency. At the same time, the part of the cabinet opening 2 inside the cabinet body of the display cabinet is usually made into a uniform white color, while the connecting platform on the first end stop assembly and the second end stop assembly will be black due to the friction of the corresponding door body, affecting the appearance.

[0125] In this embodiment, although further splitting the first end stop assembly 25 and the second end stop assembly 26 into two components will increase the production process, it reduces the generation of these corner positions and increases the production quality of each component.

[0126] In addition, each component after splitting can choose different colors and materials according to needs to meet the needs of different users, making the overall appearance of the refrigerator more beautiful. For example, after splitting and arranging, a more wear-resistant material or color can be used for the easily worn parts, effectively avoiding the problem of decreased appearance due to friction and improving user experience.

[0127] Reference Figure 14 In some embodiments, a stop portion 263 is protrudingly arranged on the side of the first end stop assembly of the third shell 261 facing the opposite side, and the stop portion 263 is located above the second connecting platform 2611. When the sliding door closes the opening, the lower door body 4 is located between the second connecting platform 2611 and the stop portion 263.

[0128] By arranging the stop portion 263, the upward movement of the lower door body 4 is limited when the sliding door closes the opening, avoiding the lower door body 4 from being separated from the cabinet opening 2, and enhancing the sealing performance.

[0129] In some embodiments, the upper door body 3 and the lower door body 4 are both arc-shaped double-layer hollow glass doors, and the height of the front end of the double-layer hollow glass door is lower than the height of the rear end.

[0130] The arc center of the arc-shaped double-layer hollow glass door is located inside the cabinet body 1, the arc-shaped arrangement makes the upper door body 3 and the lower door body 4 more beautiful, and improves the overall appearance quality of the refrigerated display cabinet 100, and the double-layer hollow glass door with the front low and the back high facilitates the user to observe the articles inside the cabinet body 1 from the front side.

[0131] With reference to Figure 17 In the embodiment, the double-layer hollow glass door can include a door frame 41 and a double-layer arc-shaped glass 42. The double-layer arc-shaped glass 42 includes two layers of arc-shaped glass plates with the same curvature, and the door frame 41 is tightly attached to the double-layer glass 42 and wrapped around the outer periphery of the double-layer arc-shaped glass 42. The two layers of arc-shaped glass 42 include an upper glass plate 421 and a lower glass plate 422.

[0132] In some embodiments, the side of the upper glass plate 421 and the side of the lower glass plate 422 facing each other can be provided with a metal plating layer. By providing the metal plating layer, the heat insulation performance of the upper door body and the lower door body is effectively improved, thereby improving the heat preservation performance of the refrigerated display cabinet and reducing energy consumption.

[0133] Of course, in other embodiments, the side of the upper glass plate 421 facing the lower glass plate 422 and the side of the lower glass plate 422 facing away from the upper glass plate 421 can be provided with the above-mentioned metal plating layer. The side of the upper glass plate 421 facing the lower glass plate 422 can be provided with a metal plating layer alone. Similarly, the side of the lower glass plate 422 facing away from the upper glass plate 421 can also be provided with a metal plating layer alone.

[0134] Further, a handle 43 is provided on the double-layer hollow glass door, which provides a force point for the user to easily push or pull to open or close the opening 24. Figure 15 The handle 43 is arranged on the door frame 41.
