Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and particularly to a refrigeration device. Background Art

[0002] Refrigerators and freezers are commonly used household appliances in people's daily lives. Freezers are widely promoted and used because of their large storage volume. For a conventional freezer, to ensure its heat preservation performance, the cabinet body of the freezer usually adopts a foaming form to form a heat preservation layer, and a sliding glass door can be configured on the cabinet opening of the cabinet body as needed to meet the requirements of users to observe the storage situation inside the cabinet and take items.

[0003] In the prior art, on the cabinet body of a freezer equipped with a sliding glass door, two layers of slide rail surfaces are formed up and down on the cabinet opening. For example, Chinese Patent CN209857472U discloses a cabinet opening for a freezer and a freezer, where 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 process, to meet the installation requirements of different steps for supporting different glass doors, the width of the steps needs to reach the set requirements. In this way, the wall thickness of the cabinet body will increase as a whole, resulting in a smaller internal volume of the cabinet body of the same specification size. At the same time, the usage amount of the foaming material will also increase additionally, leading to an increase in the manufacturing cost. In addition, the sliding friction of the glass door is large, and it is easy to have a jamming phenomenon. The push-pull sliding is not convenient, and it is impossible to achieve convenient and fast opening and closing.

[0005] In view of this, how to design a technology that reduces the wall thickness of the cabinet body and the usage amount of the foaming material to increase the effective volume of the cabinet body and reduce the manufacturing cost, and at the same time can achieve convenient and fast opening and closing of the glass door is the technical problem to be solved by this application.

[0054] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0055] The refrigeration equipment in the present application generally includes a cabinet body, a door body, and a refrigeration system. Among them, at least one refrigeration compartment is formed in the cabinet body, and the refrigeration compartment is opened and closed through the door body to meet the requirements for accessing items.

[0056] Among them, the refrigeration system performs the refrigeration cycle of the refrigeration equipment by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to achieve refrigeration of the items in the cabinet body.

[0057] The low-temperature and low-pressure refrigerant enters the compressor, and the compressor compresses it into a refrigerant gas in a high-temperature and high-pressure state 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.

[0058] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state formed by condensation in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can refrigerate the items in the cabinet by utilizing the latent heat of evaporation of the refrigerant.

[0059] As Figures 1-9 shown, the first embodiment of the present application provides a refrigeration device, including: a cabinet 1 and a door assembly 2.

[0060] A storage chamber 11 is formed in the cabinet 1, and a cabinet opening 12 is provided at the top of the cabinet 1. The cabinet opening 12 surrounds and forms a pick-up and placement opening 13 for picking up and placing items at the top of the storage chamber 11.

[0061] 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. Among them, the cabinet opening 12 of the cabinet 1 will form a pick-up and placement opening 13 at the top of the storage chamber 11, and the user can put items into the storage chamber 11 or take out the items in the storage chamber 11 through the pick-up and placement opening 13.

[0062] Correspondingly, a machine compartment can also be provided in the cabinet 1, and components such as a compressor and a condenser are installed in the machine compartment. The refrigeration method inside the cabinet 1 can be direct cooling or air cooling. For the specific refrigeration method of the refrigeration device in this embodiment, no limitation and elaboration are made here.

[0063] The refrigeration device further includes a heat-insulating door 3, which is rotatably arranged on the cabinet 1 and is configured to be arranged above the door assembly 2 in a closed state and cover the pick-up and placement opening 13.

[0064] Specifically, in order to effectively improve the overall heat insulation performance of the refrigeration device, a heat-insulating door 3 can also be configured on the cabinet 1, and the heat-insulating door 3 can also form a heat-insulating layer inside by foaming. The heat-insulating door 3 will cover the cabinet opening 12 to cover the pick-up and placement opening 13 in a closed state, and at the same time, the heat-insulating door 3 also covers above the door assembly 2.

[0065] The setting of the heat-insulating door 3 can more effectively improve the overall heat insulation performance of the quality device. At the same time, since the cabinet opening 12 is further covered by the door assembly 2 after the heat-insulating door 3 is opened, it is convenient for the user to view the items in the storage chamber 11, and at the same time, the loss of cold air in the storage chamber 11 can be effectively reduced, improving the user experience and reducing the energy consumption of the refrigeration device.

[0066] The door assembly 2 includes a plurality of glass doors that are sequentially spliced together, and two adjacent glass doors are rotatably connected together.

[0067] In an embodiment of the present application, the door assembly 2 includes a first glass door 21 and a second glass door 22 that are spliced together, and the first glass door 21 and the second glass door 22 can be folded and rotated relative to each other. The maximum angle by which the first glass door 21 and the second glass door 22 can rotate is 180°; by rotating the first glass door 21 and / or the second glass door 22, the opening and closing of the cabinet opening 13 can be achieved.

[0068] The maximum angle by which the first glass door 21 and the second glass door 22 can rotate is 180°. The first glass door 21 can be rotated 180° so that it folds above the second glass door 22, and the second glass door 22 can be rotated 180° so that it folds above the first glass door 21; thus, the access opening 13 can be fully opened, facilitating the user to take and place items from the access opening 13.

[0069] Specifically, the door assembly 2 includes a first glass door 21 and a second glass door 22 that can be spliced together. Both the first glass door 21 and the second glass door 22 can be folded and rotated. On the one hand, the access opening 13 can be opened and / or closed through the first glass door 21 and the second glass door 22. On the other hand, the user can observe the storage situation of the items in the storage room 11 through the first glass door 21 and the second glass door 22, facilitating the user to directly access the items.

[0070] Among them, since the cabinet body 1 is heat-insulated by foaming, there are certain requirements for the thickness of the foaming of the cabinet body 1. Correspondingly, in order to meet the installation requirements of the first glass door 21 and the second glass door 22, an additional installation area needs to be provided on the cabinet opening 12 of the cabinet body 1 to install the first glass door 21 and the second glass door 22. Therefore, on the premise of meeting the installation requirements of the first glass door 21 and the second glass door 22 and further meeting the heat-insulation performance of the cabinet body 1, the thickness of the cabinet body 1 is minimized 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.

[0071] In order to reduce the space in the storage room 11 of the cabinet body 1 occupied for installing the first glass door 21 and the second glass door 22, a single-layer support surface is provided on the inner side of the cabinet opening 12. That is, only a single support surface is provided on the inner side of the cabinet opening 12 to install the first glass door 21 and the second glass door 22 at the same time.

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

[0073] In this application, a single-layer support surface is adopted to install the first glass door 21 and the second glass door 22 simultaneously. Thus, it is not necessary to form multiple stepped surfaces arranged vertically on the inner side of the cabinet opening 12 to install the glass doors. In this way, it is possible to reduce the reduction of the storage volume of the storage room 11 in the cabinet 1 caused by the arrangement of multiple support surfaces on the side of the cabinet opening 12.

[0074] Meanwhile, a single-layer support surface is formed on the inner side of the cabinet opening 12, which can effectively reduce the wall thickness of the cabinet 1, and thus reduce the usage amount of the foaming material, further reducing the manufacturing cost.

[0075] Specifically, first support surfaces 121 are respectively formed on two parallel first inner walls in the cabinet opening 12. The two first support surfaces 121 are parallel to each other and located on the same horizontal plane.

[0076] Second support surfaces 122 are respectively formed on two parallel second inner walls in the cabinet opening 12. The two second support surfaces 122 are perpendicular to the first support surfaces 121 and located on the same horizontal plane.

[0077] The vertical projection shapes of the first glass door 21 and the second glass door 22 can overlap. The vertical projection shapes of the first glass door 21 and the second glass door 22 are both rectangles, and the projection areas are the same. When the access opening 13 is closed, the first glass door 21 and the second glass door 22 are spliced together to form a rectangular door body assembly and both are lapped on the support surface. Specifically, two side edges of the first glass door 21 perpendicular to its splicing edge are respectively lapped on the two first support surfaces 121, and the side edge of the first glass door 21 parallel to its splicing edge is lapped on the second support surface 121. For the second glass door 22, two side edges of the second glass door 22 perpendicular to its splicing edge are respectively lapped on the two first support surfaces 121, and the side plate of the second glass door 22 parallel to its splicing edge is lapped on the second support surface 122.

[0078] The first support surface 121 protrudes from the surface of the first inner wall. The length of the splicing edge of the first glass door 21 is greater than the distance between the two first support surfaces 121 and less than or equal to the distance between the two first inner walls, so that the two side edges of the first glass door 21 perpendicular to its splicing edge can be respectively lapped and installed on the two first support surfaces 121.

[0079] The second support surface 121 protrudes from the surface of the second inner wall. The distance between the two side edges of the first glass door 21 and the second glass door 22 parallel to their splicing edges is greater than the distance between the two second support surfaces 122 and less than or equal to the distance between the two second inner walls, so that the two side edges of the first glass door 21 and the second glass door 22 parallel to their splicing edges can be respectively lapped and installed on the two second support surfaces 122.

[0080] With the above design, the first glass door 21 and the second glass door 22 can be simultaneously lapped and installed on the same layer of supporting surface, so as to reduce the wall thickness of the cabinet body 1 of the refrigeration equipment and reduce the usage amount of the foaming material, thereby increasing the effective volume of the cabinet body 1 and reducing the manufacturing cost.

[0081] The first glass door 21 includes a first frame body 211 and a first glass plate 212, and the first glass plate 212 is arranged in the first frame body 212. The second glass door 22 includes a second frame body 221 and a second glass plate 222, and the second glass plate 222 is arranged in the second frame body 221.

[0082] Specifically, the first frame body 212 can be processed by injection molding, and the first frame body 212 wraps around the periphery of the first glass plate 213. Similarly, the second frame body 222 can be processed by injection molding, and the second frame body 222 wraps around the periphery of the second glass plate 223.

[0083] In order to facilitate the user to rotate the first glass door 21 and the second glass door 22 conveniently and quickly during use, a first handle part 213 is arranged on the upper surface of the end of the first frame body 211 away from the second frame body 221, and a second handle part 223 is arranged on the upper surface of the end of the second frame body 221 away from the first frame body 211.

[0084] Taking the first frame body 211 as an example, the first handle part 213 will be formed during the processing of the first frame body 211 to meet the requirement that the user holds it to rotate the glass door. The first handle part 213 can be a protruding structure or a concave structure. For example, a first concave groove 214 is provided on the upper surface of the end of the first frame body 211 away from the second frame body 221, and the first handle part 213 protrudes and is arranged in the first concave groove 214; by protruding the first handle part 213 in the first concave groove 214, it is convenient for the user to hold the first handle part 213. The upper surface of the first handle part 213 is basically flush with the upper surface of the first frame body 211, which can avoid the first handle part 213 occupying space.

[0085] Similarly, the second handle part 223 will be formed during the processing of the second frame body 221 to meet the requirement that the user holds it to rotate the glass door. The second handle part 223 can be a protruding structure or a concave structure. For example, a second concave groove 224 is provided on the upper surface of the end of the second frame body 221 away from the first frame body 211, and the second handle part 223 protrudes and is arranged in the second concave groove 224; by protruding the second handle part 223 in the second concave groove 224, it is convenient for the user to hold the second handle part 223. The upper surface of the second handle part 223 is basically flush with the upper surface of the second frame body 221, which can avoid the second handle part 223 occupying space.

[0086] A connecting piece is provided between the splicing edges of the first glass door 21 and the splicing edges of the second glass door 22. The connecting piece is used to realize the splicing and folding rotation of the first glass door 21 and the second glass door 22.

[0087] The number of the connecting pieces can be multiple, and the multiple connecting pieces are arranged at equal intervals, which can realize effective splicing between the first glass door 21 and the second glass door 22 and stable and effective folding rotation.

[0088] In an embodiment of the present application, the number of the connecting pieces is two, and the two connecting pieces are symmetrically arranged on both sides of the splicing edge of the glass door.

[0089] The connecting piece includes a first bushing 23, and two second bushings 24 and third bushings 25 arranged at intervals. The first bushing 23 is rotatably fitted between the second bushing 24 and the third bushing 25, and a rotatable rotating shaft 20 is arranged through the first bushing 23, the second bushing 24 and the third bushing 25.

[0090] As Figure 6 shown, the first bushing 23 can be arranged on the splicing edge of the first glass door 21, and the corresponding second bushing 24 and third bushing 25 can be arranged at intervals on the splicing edge of the second glass door 22.

[0091] Or, as Figure 7 shown, the second bushing 24 and the third bushing 25 can be arranged at intervals on the splicing edge of the first glass door 21, and the first bushing 23 can be arranged on the splicing edge of the second glass door 22.

[0092] For the first glass door 21, the splicing edge of the first glass door 21 is the side edge of the first frame body 211 close to the second frame body 221. Rotation avoidance grooves 26 are arranged on both sides of the side edge of the first frame body 211 close to the second frame body 221 along its length direction, and the first bushing 23, the second bushing 24 and the third bushing 25 are all arranged in the rotation avoidance grooves 26.

[0093] For the second glass door 22, the splicing edge of the second glass door 22 is the side edge of the second frame body 221 close to the first frame body 211. Rotation avoidance grooves 26 are arranged on both sides of the side edge of the second frame body 221 close to the first frame body 211 along its length direction, and the first bushing 23, the second bushing 24 and the third bushing 25 are all arranged in the rotation avoidance grooves 26.

[0094] By arranging the first bushing 23, the second bushing 24 and the third bushing 25 all in the rotation avoidance grooves 26, it can meet the smooth and effective rotation of the first glass door 21 and the second glass door 22, and realize the maximum rotatable angle of 180° between the first glass door 21 and the second glass door 22, that is, the folding rotation of the first glass door 21 and the second glass door 22 can be realized.

[0095] In this embodiment, the first bushing 23, the second bushing 24, and the third bushing 25 are all cylindrical, and the outer diameters of the first bushing 23, the second bushing 24, and the third bushing 25 are equal. The axial directions of the first bushing 23, the second bushing 24, and the third bushing 25 are consistent with the length direction of the splicing edge of the glass door.
