Description

Technical Field

[0001] The present application relates to a household appliance, and in particular to a refrigeration device. Background Art

[0002] Refrigerators and freezers are household appliances commonly used in people's daily lives. Freezers are widely used because of their large storage capacity. In order to ensure the thermal insulation performance, conventional freezers usually use foaming to form an insulation layer on the cabinet body, and a sliding glass door can be configured on the cabinet opening as needed to meet the user's requirements for observing the storage situation inside the cabinet and taking out items.

[0003] In the prior art, a refrigerator body equipped with a sliding glass door is provided with a slide rail surface arranged up and down on the cabinet opening. For example, Chinese patent CN209857472U discloses a cabinet opening for a refrigerator and a refrigerator, wherein a first step and a second step are formed on the cabinet opening, and the two steps are respectively used to install the glass door to meet the sliding installation requirements of the glass door.

[0004] In the actual processing, in order to meet the installation requirements of different steps supporting different glass doors, the width of the steps needs to meet the set requirements. In the prior art, the glass door of the refrigerator is set with double steps, which will increase the overall wall thickness of the cabinet, resulting in a smaller internal volume of the cabinet of the same specification and size. At the same time, the amount of foaming material used will also increase, resulting in an increase in manufacturing costs.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] The sliding door assembly 2 includes a plurality of glass doors 21 , and two adjacent glass doors 21 can slide relative to each other.

[0088] Specifically, the sliding door assembly 2 includes a plurality of glass doors 21 that can slide relative to each other, and the plurality of glass doors 21 can all slide on the cabinet opening 12. On the one hand, the access opening 13 can be opened or closed by cooperating with the plurality of glass doors 21. On the other hand, the user can observe the storage status of items in the storage room 11 through the glass doors 21, so as to facilitate the user to intuitively store and retrieve items.

[0089] 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 multiple glass doors 21, it is also necessary to additionally set up an installation area on the cabinet opening 12 of the cabinet body 1 to install the multiple glass doors 21. To this end, while meeting the installation requirements of the multiple glass doors 21 and further meeting the thermal insulation performance of the cabinet body 1, on the premise of reducing the thickness of the cabinet body 1 as much as possible, the following improvements are made to the installation method of the multiple glass doors 21.

[0090] In order to reduce the space of the storage room 11 in the cabinet 1 required for installing multiple glass doors 21, 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 install multiple glass doors 21 at the same time.

[0091] The two sides of the glass door 21 will overlap on the sliding support surface 121 on the corresponding side, and the sliding support surface 121 is used to support the corresponding side of the glass door 21 to meet the installation requirements of the glass door 21 and also meet the sliding opening and closing requirements of the glass door 21.

[0092] Among them, for two adjacent glass doors 21 , one of the glass doors 21 can slide to the upper surface of the other glass door 21 .

[0093] Specifically, when the multiple glass doors 21 are in a closed state, the multiple glass doors 21 can cover the access opening 13 to reduce the leakage of cold energy in the storage room from the access opening 13 .

[0094] When the user needs to access items through the access opening 13, the user can apply a push-pull force to one of the glass doors 21 so that the glass door 21 can slide along the sliding support surface 121 and slide to the top of another adjacent glass door 21, thereby partially opening the access opening 13 to meet the user's requirements for accessing items.

[0095] Specifically, during the assembly process, the two side portions of the glass door 21 are overlapped on the sliding support surface 121 on the corresponding side, so that the two glass doors 21 can share one sliding support surface 121 to meet the installation requirements of the sliding support on the corresponding side.

[0096] Since there is no need to configure independent sliding support surfaces 121 for each of the multiple glass doors 21, compared with 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 21, the width of each step surface needs to meet the sliding installation requirements of the glass door 21 on the corresponding side, which results in a reduction in storage volume and an increase in the thickness of the cabinet body 1.

[0097] The present application adopts a single-layer sliding support surface 121 to simultaneously install multiple glass doors 21, 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 doors 21. In this way, the storage volume of the storage room 11 in the cabinet body 1 can be reduced due to the arrangement of multiple layers of sliding support surfaces 121 on the side of the cabinet opening 12.

[0098] 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.

[0099] In one embodiment, in order to meet the requirement that one glass door 21 can slide to the top of another glass door 21, the lower surface of the end of the glass door 21 can be set as an inclined surface. When the user needs to open one of the glass doors 21, the user can press the end of the glass door 21 by hand to make the glass door 21 tilt up, and then push the glass door 21 synchronously, so that the glass door 21 can move toward the tilted end and finally slide to the upper surface of the adjacent glass door 21.

[0100] In another embodiment, in order to facilitate the user's smooth pushing and pulling operations, a sliding guide portion 129 can be provided on the sliding support surface 121, and the sliding guide portion 129 protrudes from the sliding support surface 121. The glass doors 21 are respectively provided on both sides of the sliding guide portion 129, and the sliding guide portion 129 is configured to guide the glass door 21 on one side to slide to the upper surface of the glass door 21 on the other side.

[0101] Specifically, a sliding guide portion 129 is provided on the sliding support surface 121 between two adjacent glass doors 21. Since the sliding guide portion 129 protrudes from the sliding support surface 121, when the user pushes and pulls the glass door 21 to slide open, the pushed and pulled glass door 21 needs to pass over the sliding guide portion 129 to slide to the upper surface of another adjacent glass door 21. In this way, the pushed and pulled glass door 21 can slide open smoothly through the guidance of the sliding guide portion 129.

[0102] In one embodiment, in order to facilitate the user to push and pull the glass door 21, the glass door 21 can smoothly pass over the raised sliding guide portion 129, and inclined guide surfaces 1291 can be respectively provided on both sides of the sliding guide portion 129, and the inclined guide surfaces 1291 extend obliquely from top to bottom along the length direction of the sliding support surface 121 and are connected to the sliding support surface 121;

[0103] The inclined guide surface 1291 is configured to guide the glass door 21 on the corresponding side to pass over the sliding guide portion 129 to the upper surface of the other glass door 21 .

[0104] Specifically, the bottom dimension of the sliding guide part 129 is large and the top dimension is small, so that the sliding guide part 129 forms inclined guide surfaces 1291 on both sides. In this way, when the glass door 21 is pushed and pulled, the end of the glass door 21 can be guided by the inclined guide surface 1291, so that the glass door 21 has a tendency to slide upward. As the glass door 21 continues to slide, the pushed and pulled glass door 21 will pass over the sliding guide part 129 and slide to the upper surface of another adjacent glass door 21 under the guidance of the inclined guide surface 1291 on the corresponding side, and the pushed and pulled glass door 21 is supported by the other adjacent glass door 21.

[0105] The specific process is explained with reference to the accompanying drawings: Fig.14 As shown, the multiple glass doors 21 are all in a closed state. At this time, the ends of two adjacent glass doors 21 can be close together or leave a small gap to reduce the loss of cold air in the storage room.

[0106] like Fig.15 As shown, when the user pushes or pulls one of the glass doors 21, the glass door 21 slides along the sliding support surface 121 toward the sliding guide portion 129, and under the guiding action of the sliding guide portion 129, the end of the pushed or pulled glass door 21 will gradually rise along the inclined guide surface 1291 of the sliding guide portion 129.

[0107] like Fig.16 As shown, as the pushed and pulled glass door 21 continues to be pushed and pulled, the pushed and pulled glass door 21 slides obliquely on the sliding guide portion 129 , at which time, the tilted end of the pushed and pulled glass door 21 will be located above another adjacent glass door 21 .

[0108] like Fig.17 As shown, after the pushed and pulled glass door 21 passes over the sliding guide portion 129 and completes opening, the pushed and pulled glass door 21 will be located on the upper surface of another adjacent glass door 21 and supported.

[0109] In certain embodiments, such as Fig.18 As shown, a plurality of the sliding guide portions 129 arranged at intervals can be provided on the sliding support surface 121 as needed, and the glass doors 21 are respectively provided on both sides of each sliding guide portion 129 .

[0110] Specifically, the plurality of sliding guides 129 arranged at intervals on the sliding support surface 121 can meet the installation requirements of three or more glass doors 21 to meet the usage needs of different users.

[0111] In another embodiment, the lower surface of the glass door 21 is further provided with a sliding guide surface 213, and the sliding guide surface 213 extends obliquely from bottom to top along the length direction of the sliding support surface 121 toward the edge of the glass door 21;

[0112] The sliding guide surface 213 is configured to cooperate with the sliding guide portion 129 to guide the corresponding glass door 21 to slide obliquely upward to above the sliding guide portion 129 .

[0113] Specifically, a sliding guide surface 213 is provided on the lower surface of the glass door 21, and the sliding guide surface 213 is also inclined and can match the inclined guide surface 1291 formed by the sliding guide portion 129 to guide the glass door 21 to slide and tilt smoothly, so as to slide smoothly to another glass door 21, thereby improving the convenience and smoothness of operation.

[0114] In one embodiment, the sliding guide surface 213 is further provided with anti-stuck ribs 214 at locations on both sides of the glass door 21 , and the anti-stuck ribs 214 are arranged obliquely relative to the top edge of the sliding guide portion 129 .

[0115] Specifically, the anti-stuck rib 214 can prevent the glass door 21 from being stuck at the top of the sliding guide part 129 when the glass door 21 slides to the sliding guide part 129 and tilts up, thereby reducing the jamming caused during the sliding process.

[0116] In some embodiments, the upper surface of the glass door 21 is further provided with an avoidance inclined surface 215 , and the avoidance inclined surface 215 extends obliquely from top to bottom along the length direction of the sliding support surface 121 toward the edge of the glass door 21 .

[0117] Specifically, for two adjacent glass doors 21, when the pushed and pulled glass door 21 is tilted and slid, the end edge of the other adjacent glass door 21 cannot interfere with the pushed and pulled glass door 21. By providing an avoidance inclined surface 215 on the upper surface of the glass door 21, since the avoidance inclined surface 215 extends downwardly toward the edge of the end of the glass door 21, the pushed and pulled glass door 21 can be effectively avoided.

[0118] When two adjacent glass doors 21 are in a closed state, an extended surface of the sliding guide surface 213 of one of the glass doors 21 is located above the avoidance inclined surface 215 of the other glass door 21 .

[0128] Specifically, in order to reduce the friction generated by the stacked upper and lower glass doors 21 during the sliding process, sliding support ribs 216 can be respectively provided on both sides of the frame 211. When the two glass doors 21 are stacked up and down and slide relatively, the lower glass door 21 can support the upper glass door 21 to slide relatively through the sliding support ribs 216.

[0129] In some embodiments, the frame 211 may be formed by injection molding, and the frame 211 is wrapped around the periphery of the glass plate 212 .

[0130] In order to facilitate users to push and pull the multiple glass doors 21 during use, a handle portion 217 is further provided at at least one end of the frame body 211 .

[0131] Specifically, a handle portion 217 will be formed on the frame 211 during the processing. The handle portion 217 can be a handle groove formed on the frame 211 to meet the user's manual pushing and pulling requirements while not affecting the relative sliding requirements of the glass doors 21 after being stacked.

[0132] 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 .

[0133] 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.

[0134] 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 multiple glass doors 21, 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;

[0135] 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 .

[0136] 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.

[0137] In an embodiment of the present application, the refrigeration device further comprises a storage basket 3 ; a storage space is formed in the storage basket 3 , and two sides of the storage basket 3 are respectively provided with overlapping portions 31 extending outwards.

[0139] In one embodiment, in order to meet the requirements of installing the storage basket 3, as Figure 4 and Figure 5 As shown, a lap groove 125 is provided on the sliding support surface 121 , and the lap portion 31 is located in the lap groove 125 on the corresponding side.

[0140] Specifically, 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 portions 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 the thin wall thickness of the cabinet body 1.

[0141] 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.

[0142] For the storage basket 3, the overlapping portion 31 is usually a U-shaped frame structure. The main structure of the overlapping portion 31 is located in the overlapping groove 125 and can be restricted by the inner blocking portion 127 to prevent it from falling off. The two side walls of the overlapping portion 31 are located in the corresponding notches 126.

[0143] Similarly, if Figure 8 As shown, in order to meet the installation overlap requirements of the storage basket 3, an overlap bearing surface 120 can also be provided on both sides of the cabinet opening 12, and the overlap bearing surface 120 is located below the sliding support surface 121 on the corresponding side and arranged on the inner side of the sliding support surface 121.

[0144] Specifically, the overlapping bearing surface 120 is arranged inside and below the sliding support surface 121 , so that the overlapping portion 31 of the storage basket 3 can be overlapped on the overlapping bearing surface 120 on the corresponding side for installation.

[0145] In one embodiment of the present application, the refrigeration device further includes a heat-insulating door 4, which is rotatably disposed on the cabinet body 1, and is configured to be arranged above the sliding door assembly 2 and cover the access opening 13 in a closed state.
