[0067] The refrigerator is a common appliance in daily life, which is widely used today. Users can store food in the refrigerator to avoid food spoilage.

[0068] The refrigerator in the embodiment includes a cabinet 1 and an inner container 2.

[0069] The cabinet 1 is used to form the overall appearance of the refrigerator. The cabinet 1 is generally in the shape of a rectangular frame. The top of the cabinet 1 and the bottom of the cabinet 1 are opposite ends. The height direction of the cabinet 1 is from the top of the cabinet 1 to the bottom of the cabinet 1. The left side of the cabinet 1 and the right side of the cabinet 1 are opposite sides. The width direction of the cabinet 1 is from the left side of the cabinet 1 to the right side of the cabinet 1. The front side of the cabinet 1 and the rear side of the cabinet 1 are opposite sides. The thickness direction of the cabinet 1 is from the front side of the cabinet 1 to the rear side of the cabinet 1. The inner container 2 is arranged in the cabinet 1.

[0070] The inner container 2 is internally provided with a storage chamber 21 for placing articles, the storage chamber 21 is provided with a chamber opening, the chamber opening is arranged on the front side of the cabinet 1, and the storage chamber 21 can be a refrigeration temperature environment, a freezing temperature environment, or a normal temperature environment. The chamber opening is provided with a door body 3, the door body 3 is arranged in a straight plate shape on the front side of the cabinet 1, and the door body 3 is connected to the cabinet 1 in a hinged manner to open or close the storage chamber 21.

[0071] It can be understood that the refrigerator also includes a refrigeration system and an air supply system. The refrigeration system is installed in the cabinet 1, and is used to provide cold air to the storage chamber 21; the refrigeration system generally refers to a closed system composed of a compressor, an evaporator, a condenser, a drying filter, a return air pipe, a throttling device and the like, and a refrigerant, and each component is distributed at different positions of the cabinet 1 according to its structural characteristics to meet the requirements of its corresponding functions. The working process of the refrigeration system mainly includes compression process, condensation process, throttling process and evaporation process. The compression process is as follows: after the power cord of the refrigerator is plugged in and the contacts of the temperature controller are connected, the compressor starts to work, the low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor, and after being compressed into high-temperature and high-pressure refrigerant gas by the compressor, it is discharged into the condenser. The condensation process is as follows: the high-temperature and high-pressure refrigerant gas exchanges heat with the external environment through the condenser, the temperature drops, and gradually becomes a normal-temperature and high-pressure refrigerant saturated vapor, and then becomes a refrigerant saturated liquid. The throttling process is as follows: the condensed refrigerant saturated liquid flows into the throttling device after being filtered to remove water and impurities by the drying filter, and is throttled and depressurized by the throttling device, and the refrigerant becomes a normal-temperature and low-pressure wet vapor. The evaporation process is as follows: the normal-temperature and low-pressure wet vapor enters the evaporator, starts to absorb heat to vaporize, reduces the temperature of the evaporator and its surroundings, realizes refrigeration, and makes the refrigerant into a low-temperature and low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor to repeat the above process, and energy conversion is carried out through the state change of the refrigerant to transfer the heat in the refrigerator to the air outside the cabinet, thereby realizing the refrigeration cycle of the refrigerator.

[0072] The air supply system is installed in the cabinet 1 and is used to provide power for the flow of cold air; the air supply system generally includes a fan and a flow guide cavity, in some embodiments, the air inlet end of the flow guide cavity is arranged close to the fan, and the air outlet end of the flow guide cavity is arranged away from the fan; in other embodiments, the air outlet end of the flow guide cavity is arranged close to the fan, and the air inlet end of the flow guide cavity is arranged away from the fan. The fan drives the air in the flow guide cavity, and the evaporator is correspondingly arranged in the flow guide cavity. The cold air cooled by the evaporator flows along the flow guide cavity under the driving of the fan, passes through the installation space formed between the inner container 2 and the cabinet 1, and finally enters the storage chamber 21 to perform refrigeration operation on the storage chamber 21.

[0073] On the basis of the above structure, as shown in Figure 1-11, the first aspect of the embodiments of the present application proposes a refrigerator, comprising: a cabinet 1, an inner container 2, a door body 3, a hinge 4 and a crossbeam assembly 5, the cabinet 1 has a containing cavity with a front opening, the inner container 2 is arranged in the cabinet, and a mounting space 11 is formed between the outer top wall of the inner container 2 and the inner top wall of the cabinet 1, the inner container 2 has a storage room 21 with a front opening, the door body 3 is hingedly connected with the cabinet 1 for opening or closing the storage room 21, the door body 3 is rotationally connected with the rotating shaft of the hinge 4, the crossbeam assembly 5 is located on the upper front side of the cabinet 1, the crossbeam assembly 5 comprises a mounting piece 51, the mounting piece 51 comprises a forward mounting surface 511 and a buckle 512 arranged on the mounting surface 511, the hinge 4 is located on the mounting surface 511, and the hinge 4 is clamped with the buckle 512; the hinge 4 and the mounting piece 51 are further fixedly connected through a fastener 6, the mounting surface 511 is provided with a first mounting hole 513 and a second mounting hole 514, the hinge 4 is provided with a first fixing hole 41 and a second fixing hole 42, the first mounting hole 513 and the first fixing hole 41 are correspondingly arranged, the second mounting hole 514 and the second fixing hole 42 are correspondingly arranged, the fastener 6 respectively passes through the first fixing hole 41 and the second fixing hole 42 and is respectively connected with the first mounting hole 513 and the second mounting hole 514; the buckle 512, the first fixing hole 41 and the second fixing hole 42 are sequentially arranged close to the cabinet 1 in the horizontal direction, the second fixing hole 42 is open on the outer side in the horizontal direction to form a horizontally arranged U-shaped structure. The mounting piece 51 preferably adopts a plastic structure, which is light in weight, convenient to punch and good in durability, and is convenient for the installation of the hinge 4.

[0074] Based on the above technical scheme, the refrigerator of the present application, the cabinet 1 is used to accommodate the inner container 2, the inner side wall of the inner container 2 defines the storage chamber 21, the door body 3 is closed to constitute the refrigeration part, the hinge 4 is arranged on the front side of the cross beam assembly 5, so that when the door body 3 is closed, the hinge 4 can be hidden behind the door body 3, the hidden design effectively improves the integrity of the appearance of the refrigerator, and the refrigerator is more beautiful, and in order to realize the front side installation of the hinge 4, through the cooperation of the fastener 6 and the buckle 512, the fastener 6 is pre-fixed on the second mounting hole 514, the U-shaped second fixing hole 42 of the hinge 4 is laterally close to the pre-fixed fastener 6 to make the pre-fixed fastener 6 in the second fixing hole 42, then one end of the hinge 4 is clamped into the buckle 512, finally the fastener 6 of the first fixing hole 41 and the second fixing hole 42 is fixed on the first mounting hole 513 and the second mounting hole 514, so that the installation and fixation of the hinge 4 are realized simply and conveniently, and due to the flexible characteristics of the transverse position adjustment of the U-shaped second fixing hole 42, the positioning problem does not exist in the installation process of the hinge 4, the position tolerance requirement of the fixing hole is significantly reduced, and the installation method is simple and easy to operate, further reducing the operation difficulty of workers.

[0075] In some embodiments, the fastener 6 adopts a screw, which is simple in structure, easy to obtain and low in cost.

[0076] In order to realize the heat preservation of the refrigerator, avoid the waste of electricity caused by the leakage of cold air, and fill the heat preservation layer between the cabinet 1 and the inner container 2 of the refrigerator, the heat preservation layer is made of heat preservation material, usually polyurethane foam plastic, which is a kind of foaming plastic with good heat insulation performance, so that the accommodating cavity of the refrigerator cabinet 1 is filled with the heat preservation layer in addition to the inner container 2, and the door body 3 is also provided with a heat preservation layer, which cooperates with the cabinet 1 to realize excellent heat insulation. The inner container 2 is the main placement position of the food and other cold storage and freezing articles in the refrigerator, and a plurality of shelves are preferably arranged in the inner container 2, so as to facilitate the separate storage of the articles and effectively improve the available space. The shelf is preferably arranged on the door body 3 for storing small articles, further improving the space utilization.

[0077] In addition, since the hinge 4 in the embodiment is arranged on the front side of the cross beam assembly 5, the hinge 4 is arranged in a hidden manner relative to the whole refrigerator, so that the refrigerator does not have the protruding hinge 4 cover of the conventional refrigerator protruding from the top of the refrigerator, thereby better meeting the use requirements of the built-in refrigerator. The built-in refrigerator is a refrigerator installation form in which the refrigerator is placed in a cabinet to realize the combination of the refrigerator and the cabinet. In recent years, with the progress of society and the improvement of people's living standards, ordinary users pay more and more attention to the placement position and placement manner of the refrigerator in the family. In view of the current home decoration style, many families begin to pursue style integration, so more and more families choose built-in refrigerators. Since the hinge 4 of the refrigerator in the embodiment does not have a protruding structure, the installation between the refrigerator and the cabinet is more convenient and easy, and the distance between the refrigerator and the cabinet can be arranged more closely, so that the aesthetic appearance of the built-in refrigerator is further improved.

[0078] In some embodiments of the present application, as shown in FIGS. 5-7, the refrigerator further comprises a hinge cover 7, the door body 3 is provided with a containing groove 31 for accommodating the protruding part of the hinge 4, the hinge cover 7 is partially located in the containing groove 31 and covers the hinge 4. The containing groove 31 provided in the door body 3 can accommodate the hinge 4 and the hinge cover 7, so that the hinge space arranged above the cabinet 1 in the prior art is changed to be arranged inside the door body 3, and the hinge 4 is changed from being arranged above the cabinet 1 to being arranged on the front side of the cabinet 1. Although the structure of the hinge 4 cannot be seen when the refrigerator is closed, the metal hinge 4 can still be seen at the corner position when the door is opened. The refrigerator of the embodiment is provided with the hinge cover 7, which is made of plastic or other coated materials and covers the hinge 4, so as to further improve the aesthetic appearance of the refrigerator after the door is opened. It should be noted that the hinge 4 usually has a connecting part 44 and a rotating shaft part, the connecting part 44 is in the form of a plate and is fixedly installed on the front side of the cross beam assembly 5, and the rotating shaft part includes a rotating shaft 45 and a bent connecting plate 46 connecting the rotating shaft 45 and the mounting part 44. In order to completely shield the hinge 4, the hinge cover 7 includes a first shielding part 71 connected with the cabinet 1 and a second shielding part 72 connected with the first shielding part 71. The first shielding part 71 is in the form of a plate and completely shields the connecting part 44. The second shielding part 72 is in the form of a box and covers the connecting plate 46. The part of the rotating shaft 45 inserted into the door body 3 does not need to be shielded, so that the complete shielding of the hinge 4 is realized, and the aesthetic appearance is greatly improved.

[0079] Specifically, as shown in FIGS. 6 and 7, the refrigerator further comprises a corner cover 8, the vertical direction and the horizontal direction of the accommodating groove 31 are open away from one side of the door body 3, and the corner cover 8 is arranged on the opening of the accommodating groove 31. The corner cover 8 can cover the top opening and the side opening of the accommodating groove 31, which not only makes the refrigerator more beautiful, but also avoids dust and the like from entering the accommodating groove 31, thereby avoiding complaints of users caused by the need to clean the accommodating groove 31 frequently. The corner cover 8 is installed in a manner of being clamped with the refrigerator door body 3, the rear side of the corner cover 8 is spaced apart from the front side of the hinge cover 7, the door body 3 drives the corner cover 8 to rotate together with the door body 3 when the door body 3 is opened, and the corner cover 8 does not contact the hinge cover 7 when the door body 3 is opened or closed, thereby avoiding interference.

[0080] Specifically, as shown in FIGS. 4-7 and FIGS. 9 and 10, the crossbeam assembly 5 further comprises a mounting portion 52, the mounting portion 52 is provided with the mounting member 51 on both sides in the horizontal direction, the two mounting members 51 on both sides of the mounting portion 52 are symmetrically arranged, and the hinge 4 is mounted on one of the mounting members 51. Because different families have different requirements for the use demand and the space size of the refrigerator, the refrigerator may need to be interchanged between left opening and right opening to meet the needs of users. Based on this, the installation of the hinge 4 needs to consider that the hinge 4 can be installed interchangeably on the left and right sides. Therefore, the front side wall of the crossbeam assembly 5 needs to be provided with buckles 512, first mounting holes 513 and second mounting holes 514 on both left and right sides, and the mounting structures on both left and right sides need to be symmetrically arranged. In this way, the refrigerator can be installed according to the different opening directions required by users, thereby improving the satisfaction of customers.

[0081] More specifically, as shown in FIGS. 5-7, the refrigerator further comprises a decorative plate 9 and a display screen 10, the decorative plate 9 is arranged on the front side of the mounting member 51 opposite to the hinge cover 7, the display screen 10 is arranged between the hinge cover 7 and the decorative plate 9 and covers the front side of the mounting portion 52, and the front side of the first shielding portion 71 of the hinge cover 7, the decorative plate 9 and the display screen 10 are flush.

Two fasteners 6 are respectively inserted into the first through hole 541 and the second through hole 542 through the first mounting hole 513 and the second mounting hole 514. Since the mounting piece 51 is usually made of plastic material, the reinforcing iron 54 is preferably made of metal material, and the installation of the hinge 4 is more stable through the reinforcement of the metal structure. In this embodiment, the strength of the mounting structure is improved by the reinforcing iron 54, and the stability and reliability of the mounting structure are further improved.

[0084] More specifically, as shown in FIG. 10, 11, the rear side of the mounting piece 51 is provided with a surrounding wall 55, the surrounding wall 55 defines a reserved space 56 for accommodating the reinforcing iron 54, the upper and lower sides of the surrounding wall 55 are respectively provided with a clamping block 57, the clamping block 57 is provided with a guide slope 571, and the reinforcing iron 54 is clamped to the reserved space 56 through the clamping block 57.

The clamping block 57 has a certain elasticity, and the clamping blocks 57 arranged on the upper and lower sides of the surrounding wall 55 are respectively bent upward and downward until the reinforcing iron 54 is completely embedded in the reserved space 56, and the clamping block 57 restores its elasticity, and the protruding part of the clamping block 57 clamps the reinforcing iron 54, thereby completing the installation of the reinforcing iron 54.

[0085] In some embodiments of the present application, as shown in FIG. 7-9, the rotating shaft of the hinge 4 is a hollow structure, and the rotating shaft of the hinge 4 is an arc-shaped non-integer circular shape. The hollow rotating shaft can reduce the weight of the hinge 4, facilitate installation and use, and the rotating shaft of the hinge 4 is arc-shaped, which can be combined with the hollow hinge shaft to consider the wiring of the refrigerator.

[0086] As shown in FIG. 1-11, the second aspect of the embodiments of the present application proposes a mounting method of the refrigerator as described above, comprising the following steps:

[0087] S1, inserting the rotating shaft of the hinge 4 into the shaft hole of the door body 3;

[0088] S2, pre-fixing the fastener 6 to the second mounting hole 514, so that the fastener 6 is partially inserted into the second mounting hole 514;

[0089] S3, laterally approaching the pre-fixed fastener 6 with the second fixing hole 42 of the U-shaped hinge 4, so that the pre-fixed fastener 6 is placed in the second fixing hole 42;

Finally, the fastener 6 of the first fixed hole 41 and the second fixed hole 42 is fixed on the first mounting hole 513 and the second mounting hole 514, thereby simply and conveniently realizing the installation and fixation of the hinge 4. And due to the flexible characteristics of the transverse position adjustment of the U-shaped second fixed hole 42, the hinge 4 installation process also does not have the problem of inaccurate positioning, and the position tolerance requirements of the fixed hole are significantly reduced. At the same time, the installation method is simple and easy to operate, further reducing the operation difficulty of workers. It should be noted that the hinge 4 clamped into the buckle 512 can adopt different ways, and two installation embodiments are listed here: the elastic clamping mode is that the buckle 512 has elasticity, and the buckle 512 is provided with a slope, the pre-tightened fastener 6 is placed in the second fixed hole 42 by laterally approaching the pre-tightened fastener 6 of the second fixed hole 42, the other end of the hinge 4 opposite to the second fixed hole 41 faces downward and gradually approaches the buckle 512 and presses the buckle 512, under the guidance of the slope, the hinge 4 pushes open the buckle 512 into the space below, and the installation clamping is completed; the sliding clamping mode is that the pre-tightened fastener 6 is placed in the second fixed hole 42 by laterally approaching the pre-tightened fastener 6 of the second fixed hole 42, at this time the hinge 4 can first enter the installation space of the buckle 512, and since the second fixed hole 42 is a U-shaped opening to the right, the hinge 4 can move to the left to enter the buckle 412 to complete the clamping. After the above two clamping modes are completed, further fixation and installation are carried out through the fastener 6, and the whole installation process is finally completed.

[0094] In summary, the refrigerator and the mounting method thereof, the box body 1 is used for containing the inner container 2, the inner side wall of the inner container 2 defines the storage chamber 21, the door body 3 is closed to constitute the refrigeration part, the hinge 4 is arranged on the front side of the cross beam assembly 5, so that when the door body 3 is closed, the hinge 4 can be hidden behind the door body 3, the hidden design effectively improves the integrity of the appearance of the refrigerator, and the refrigerator is more beautiful, and in order to realize the front side installation of the hinge 4, through the cooperation of the fastener 6 and the buckle 512, the fastener 6 is pre-fixed on the second mounting hole 514, the lateral of the U-shaped second fixing hole 42 of the hinge 4 is close to the pre-fixed fastener 6, the pre-fixed fastener 6 is arranged in the second fixing hole 42, then one end of the hinge 4 is clamped into the buckle 512, finally the two fasteners 6 in the first fixing hole 41 and the second fixing hole 42 are fixed in the first mounting hole 513 and the second mounting hole 514, so that the installation and fixation of the hinge 4 are simply and conveniently realized, and due to the flexible characteristics of the transverse position adjustment of the U-shaped second fixing hole 42, the installation process of the hinge 4 also does not have the problem of inaccurate positioning, the tolerance requirement of the fixing hole position is significantly reduced, and the installation method is simple and easy to operate, further reducing the operation difficulty of workers.

[0095] At present, more and more families use the refrigerator door as the cabinet door, and the size of the semi-embedded refrigerator needs to be matched with the size of the cabinet to avoid interference between the refrigerator and the cabinet. This undoubtedly brings inconvenience to the design of the size of the refrigerator and the size of the cabinet, therefore, it is necessary to provide a refrigerator to prevent the door body of the refrigerator from interfering with the cabinet.

[0096] As shown in FIGS. 12-17, the third aspect of the embodiments of the present application proposes a refrigerator installed in a cabinet 100 having a first inner side wall surface 111 and a second inner side wall surface 112 opposite in the width direction, the refrigerator comprising: a cabinet 1 having a first outer side wall surface 12 and a second outer side wall surface 13 opposite in the width direction, an inner container 2 installed in the cabinet 1 and having a storage compartment 21 with a front opening, a hinge 4 installed on the cabinet 1 and comprising a vertical rotating shaft 45 located on the front side of the cabinet 1 and close to the first outer side wall surface 12, and a door body 3 provided on the front side of the cabinet 1 and rotatably connected to the rotating shaft 45 for opening and closing the storage compartment 21, the door body 3 having a first side surface 30 and a second side surface 32 opposite in the width direction, the first inner side wall surface 111 being on the same side as the first outer side wall surface 12, the second inner side wall surface 112 being on the same side as the second outer side wall surface 13, the first side surface 30 being on the same side as the first outer side wall surface 12, and the second side surface 32 being on the same side as the second outer side wall surface 13; wherein the intersection line of the plane where the front surface of the door body 3 is located and the plane where the first side surface 30 is located is defined as a first auxiliary line 33, the distance from the axis of the rotating shaft 45 to the first auxiliary line 33 is L1, and the distance from the axis of the rotating shaft 45 to the plane where the first outer side wall surface 12 is located is L2, L1 and L2 satisfying: L1≤L2.

[0097] Based on the above technical solution, the refrigerator of the present application adopts the structure of a semi-embedded refrigerator, the cabinet 1 is installed in the cabinet 100, the door of the refrigerator is used to replace the door of the cabinet 100, the cabinet 1 is used to accommodate the inner container 2, the inner side wall of the inner container 2 defines the storage compartment 21, the door body 3 is closed to form the refrigeration and / or freezing part, the hinge 4 is installed on the cabinet 1 and the door body 3 is installed on the rotating shaft 45 of the hinge 4, so that the door body 3 can rotate relative to the cabinet 1 to realize the opening or closing of the storage compartment 21, and during the rotation of the door body 3, since the distance from the axis of the rotating shaft 45 to the first auxiliary line 33 is less than the distance from the axis to one side of the cabinet 1, no matter how far the distance between the cabinet 1 and the cabinet 100 is, it can be ensured that the door body 3 is always inside the cabinet 1 during the rotation, thereby avoiding the contact between the door body 3 and the cabinet 100.

[0098] In order to realize the heat preservation of the refrigerator, avoid the waste of electricity caused by the leakage of cold air, the foaming layer is filled between the cabinet 1 and the inner container 2, which is made of thermal insulation material, and polyurethane foam plastic is usually used, which is a kind of foaming plastic with good thermal insulation performance. At the same time, the door body 3 is also provided with a foaming layer, which cooperates with the cabinet 1 to realize excellent heat insulation. In order to further improve the sealing performance between the cabinet 1 and the door body 3, reduce the problem of electricity waste caused by the leakage of cold air, the door seal structure is also provided between the cabinet 1 and the door body 3. The door seal is preferably made of flexible material, such as rubber structure, which is arranged at the joint of the door body 3 and the cabinet 1 and installed on the door body 3, and surrounds the front opening of the cabinet 1. When the door is closed, it can play a good sealing effect between the cabinet 1 and the door body 3, preventing cold air from flowing out of the gap between them. When the door is opened, the door seal can be opened together with the door body 3 and moved, which will not affect the normal use of the refrigerator. The inner container 2 is the main placement position of the food and other cold storage and freezing articles in the refrigerator, and a plurality of shelves are preferably arranged inside to facilitate the separate storage of articles and effectively improve the available space. At the same time, the shelf is preferably arranged on the door body 3 for storing small articles, further improving the space utilization.

[0099] In addition, in the present application, the hinge 4 of the refrigerator can be arranged on the front side of the cabinet 1. Compared with the conventional installation of the hinge 4 on the top of the cabinet 1, the hinge 4 of the present application is hiddenly arranged, that is, when the door body 3 is closed, the conventional hinge 4 of the refrigerator does not protrude from the top of the refrigerator, so as to be more suitable for the use requirement of the embedded refrigerator. Since the refrigerator hinge 4 in the present embodiment does not have a protruding structure, the installation between the refrigerator and the cabinet 100 is more convenient and easy, and the distance between the refrigerator and the cabinet 100 can be arranged more closely, so that the aesthetic appearance of the embedded refrigerator is further improved. At the same time, for the installation of the hinge 4, only the distance relationship between the shaft center and the first auxiliary line 33 and the side wall of the cabinet 1 needs to be met, without other installation position requirements, so that this installation requirement can also adapt to the structure form of the front side installation of the hinge 4, and the universality is higher.

[0100] As shown in FIGS. 12-15, the fourth aspect of the embodiments of the present application proposes a refrigerator installed in a cabinet 100 having a first inner side wall surface 111 and a second inner side wall surface 112 opposite in the width direction, the refrigerator comprising: a cabinet 1 having a first outer side wall surface 12 and a second outer side wall surface 13 opposite in the width direction, an inner container 2 installed in the cabinet 1 and having a storage compartment 21 with a front opening, a hinge 4 installed on the cabinet 1 and comprising a vertical rotating shaft 45 located on the front side of the cabinet 1 and close to the first outer side wall surface 12, and a door body 3 provided on the front side of the cabinet 1 and rotatably connected to the rotating shaft 45 for opening and closing the storage compartment 21, the door body 3 having a first side surface 30 and a second side surface 32 opposite in the width direction, the first inner side wall surface 111 being on the same side as the first outer side wall surface 12, the second inner side wall surface 112 being on the same side as the second outer side wall surface 13, the first side surface 30 being on the same side as the first outer side wall surface 12, and the second side surface 32 being on the same side as the second outer side wall surface 13; wherein the intersection line of the plane where the front surface of the door body 3 is located and the plane where the first side surface 30 is located is defined as a first auxiliary line 33, the distance from the axis of the rotating shaft 45 to the first auxiliary line 33 is L1, the distance from the axis of the rotating shaft 45 to the plane where the first outer side wall surface 12 is located is L2, and the distance from the first outer side wall surface 12 to the first inner side wall surface 111 is L3, L1, L2 and L3 satisfy: L1-L2≤0.5mm and 2mm≤L3≤3mm.

[0101] Based on the above technical solutions, the refrigerator of the present application adopts the structure of a semi-embedded refrigerator, the cabinet 1 is installed in the cabinet 100, the door of the refrigerator is used to replace the door of the cabinet 100, the cabinet 1 is used to accommodate the inner container 2, the inner side wall of the inner container 2 defines the storage compartment 21, the door body 3 is closed to constitute the refrigeration and / or freezing part, the hinge 4 is installed on the cabinet 1 and the door body 3 is installed on the rotating shaft 45 of the hinge 4, so that the door body 3 can rotate relative to the cabinet 1 to realize the opening or closing of the storage compartment 21, the distance between the cabinet 1 and the cabinet 100 is 2mm to 3mm, which leaves a mounting allowance for the instability of the foaming process, so that the assembly of the cabinet 1 and the cabinet 100 is more stable, and on this basis, the distance from the axis to the first auxiliary line 33 is set to be greater than the distance from the axis to one side of the cabinet 1 and not greater than 0.5mm, which can avoid the interference between the door body 3 and the cabinet 100 in the rotating process due to the error in production or assembly.

[0102] For the cabinet 100, the width of the standard cabinet 100 is 600 mm, which can be ensured with little error, but the size of the refrigerator cannot be done with such a small error, because the refrigerator in the production process will exist a foaming process, which is to fill the box 1 and the inner container 2 through the foaming material, and the controllability of the foaming process is poor, in order to ensure the heat preservation effect of the refrigerator, the foaming layer should be filled between the box 1 and the inner container 2 as much as possible, which is easy to cause the foaming amount to be too large to cause the deformation of the outer surface of the refrigerator, if the refrigerator and the cabinet 100 do not leave a fitting gap, then it is very likely that the refrigerator cannot be assembled into the cabinet 100, which will cause serious complaints of customers. Therefore, in order to avoid this situation, the width of the refrigerator is usually designed to be 594 mm to 596 mm, so as to leave a fitting allowance of 2 mm to 3 mm, that is, there will be a gap of 2 mm to 3 mm between the box 1 of the refrigerator and the cabinet 100. Under this assembly condition, the door body 3 does not need to be necessarily located inside the box 1 during the rotation process, but can be allowed to exceed 0.5 mm at the maximum position, avoiding the problem of too strict assembly conditions and causing the qualified rate to decrease, but if the size exceeds too much, it may cause the problem of interference between the door body 3 and the cabinet 100 due to the uncontrollable foaming process.

[0103] In some embodiments of the present application, as shown in Figures 15, 17 and 23, the distance from the first outer wall surface 12 to the first inner wall surface 111 is 2.5 mm. When the box 1 is assembled into the cabinet 100, the width of the cabinet 100 is selected to be 600 mm, the width of the box 1 is 595 mm, and a gap of 2.5 mm is left on both sides between the box 1 and the cabinet 100, which can realize the stable assembly of the box 1.

[0104] In some embodiments of the present application, as shown in FIGS. 21-23, when the door body 3 is opened to the maximum angle, the included angle between the door body 3 and the front side wall surface of the cabinet 1 is 100°-110°, and the front side wall surface of the cabinet 1 refers to the wall surface of the front side of the cabinet 1. The door body 3 has a door shell wall surface 34, that is, the wall surface on the outer side in the thickness direction of the door body 3. The distance L4 between the door shell wall surface 34 and the first inner side edge 113 of the cabinet 100 close to the first inner side wall surface 111 satisfies L4≥1 mm. The first inner side edge 113 refers to the front edge of the first inner side wall surface 111 in the thickness direction. Since the cabinet 1 of the semi-embedded refrigerator is embedded in the cabinet 100, by limiting the angle of the refrigerator when the door is opened, the inner side edge of the cabinet 100 can be prevented from being hit when the door of the refrigerator is opened, thereby preventing damage to the cabinet 100 or the door body 3. On this basis, it should be noted that the maximum opening angle of the door of a conventional refrigerator is at least 90°, so that the user can easily access the goods and the drawers 80, shelves and the like in the refrigerator, but considering that shelves can also be arranged on the door body 3 and considering the instability of the foaming of the door body 3, the opening angle of the door body 3 is at least 100°, which can ensure that the user can access the goods, shelves and drawers 80 without being restricted and without interference with the door body 3. At the same time, if the opening angle of the door body 3 is too large, such as 112°, the door body 3 can collide with the inner side edge of the cabinet 100. Therefore, in the present embodiment, the maximum opening angle of the door body 3 is set to be less than 110°, so as to avoid collision and ensure the safety of the door body 3 in use. In some embodiments, the maximum opening angle of the door body 3 is 110°, and at this time, the distance between the door shell wall surface 34 of the door body 3 and the first inner side edge 113 of the cabinet 100 is 1 mm, so as to ensure the safety in use.

[0105] Specifically, as shown in FIGS. 21-23, when the door body 3 is opened to the maximum angle, the included angle between the door body 3 and the front side wall surface of the cabinet 1 is 105°, and the distance L4 between the door shell wall surface 34 and the first inner side edge 113 satisfies L4=3 mm. Since the maximum angle between the door body 3 and the refrigerator needs to be between 100° and 110°, the maximum angle is more preferably 105°, which can ensure that the maximum angle still meets the requirements within the allowable error range, and the distance between the door shell wall surface 34 of the door body 3 and the first inner side edge 113 of the cabinet 100 is 3 mm at this time, which further improves the safety during use. It should be noted that in some embodiments, a limiting block is arranged on the front side wall surface of the cabinet 1, and when the door body 3 is opened to the maximum angle, the limiting block contacts the hinge 4 to prevent the door body 3 from being continuously opened, which is simple and reliable in structure.

[0106] In some embodiments of the present application, as shown in FIGS. 18-20, a first foaming layer 60 is filled between the inner side wall of the cabinet 1 and the outer side wall of the inner container 2, and a second foaming layer 70 is filled in the door body 3, and the first foaming layer 60 and the second foaming layer 70 are used to provide insulation for the refrigerator. The first foaming layer 60 and the second foaming layer 70 together fill the refrigerator, which can provide the required insulation function for the refrigerator.

[0107] Specifically, as shown in FIGS. 14, 18, and 21, the refrigerator further comprises a drawer 80, which is installed in the inner container 2, and the outer side wall of the drawer 80 in the width direction is slidably connected with the inner side wall of the inner container 2 in the width direction, so that the drawer 80 can be pulled out or pushed back in the front-back direction. Since the storage compartment 21 of the inner container 2 has a large space, in order to fully utilize the space of the storage compartment 21, the drawer 80 can be arranged in the inner container 2, and the drawer 80 is slidably connected with the inner container 2, so as to realize the taking and returning of the drawer 80. Preferably, the inner container 2 is provided with a slide rail and a roller, the slide rail is used to guide the sliding of the drawer 80 thereon, and the roller can change the sliding friction of the drawer 80 into rolling friction, thereby reducing the friction and making the drawer 80 easier to use.

[0108] More specifically, as shown in FIGS. 18-21, the door body 3 has a door inner side wall surface 35, the inner container 2 has a third inner side wall surface 22 close to the first outer side wall surface 12 in the width direction, the drawer 80 has a third outer side wall surface 81 close to the first outer side wall surface 12 in the width direction, when the door body 3 is opened and the included angle between the door body 3 and the cabinet 1 is 90°, and the thicknesses of the first foaming layer 60 and the second foaming layer 70 close to the first outer side wall surface 12 are the same, the distance between the door inner side wall surface 35 and the third inner side wall surface 22 is L5, the distance between the third inner side wall surface 22 and the third outer side wall surface 81 is L6, and L5 and L6 satisfy: L5 < L6. When the door body 3 is opened to 90°, the ideal state of the door body 3 is that the inner side wall thereof cannot exceed the inner side surface of the inner container 2, so that the drawer 80 can be taken out very smoothly, but this will cause the inner container 2 and part of the first foaming layer 60 to exceed the door inner side, so that part of the first foaming layer 60 is exposed, which affects the appearance. Based on the above description, the present application uses the installation gap between the drawer 80 and the inner container 2 to avoid the problem of affecting the appearance, when the door body 3 is opened to 90°, the distance between the inner side wall of the door body 3 and the inner side wall of the inner container 2 in the width direction is less than the single-sided gap between the drawer 80 and the inner container 2, so that the drawer 80 will not interfere with the door body 3 when in use, thereby ingeniously using the installation gap to offset the size deviation and solve the appearance problem.

[0109] Specifically, as shown in FIGS. 18-21, the door body 3 has a door inner side wall surface 35, the inner container 2 has a third inner side wall surface 22 close to the first outer side wall surface 12 in the width direction, the drawer 80 has a third outer side wall surface 81 close to the first outer side wall surface 12 in the width direction, when the door body 3 is opened and the included angle between the door body 3 and the cabinet 1 is 90°, the door inner side wall surface 35 is closer to the first outer side wall surface 12 than the third inner side wall surface 22 or flush with the third inner side wall surface 22 in the width direction, and the thickness of the first foaming layer 60 close to the first outer side wall surface 12 is not less than the thickness of the second foaming layer 70. When the door body 3 is opened to 90°, the door inner side wall surface 35 of the door body 3 is arranged outside the inner container 2 in the width direction, and the thickness of the first foaming layer 60 is not less than the thickness of the second foaming layer 70, which not only ensures smooth taking out of the drawer 80, but also has good filling performance and does not affect the heat preservation performance.

[0110] In some embodiments of the present application, as shown in FIGS. 15, 17 and 23, the thickness of the door body 3 is 55 mm, the door body 3 has a door inner side wall surface 35, the distance from the axis of the hinge shaft 45 to the door inner side wall surface 35 is not less than 40 mm, and the distance from the axis of the hinge shaft 45 to the first side surface 30 is not greater than 14 mm. The door body 3 bears the heat preservation function of the front side of the refrigerator, so the thickness of the door body 3 cannot be too small, otherwise it cannot meet the heat preservation requirement after filling and foaming, and the thickness of the door body 3 also cannot be too large, otherwise it will cause waste of materials and the reliability of the hinge 4 will be greatly reduced. Based on a large amount of data verification, the thickness of the door body 3 is selected as 55 mm, which can meet the above two aspects of use requirements, and in order to meet the non-interference requirement of the door body 3 and the cabinet 100, the position of the axis of the hinge 4 is limited, which is verified according to the distance from the axis to the first auxiliary line 33, and the distance from the axis to the outer surface of the door body shell should be not greater than 15 mm, i.e. the thickness of the door body 3 is 55 mm minus the minimum distance of 40 mm between the axis and the inner side wall of the door body 3, and the distance from the axis to the side wall of the door body 3 is not greater than 14 mm, which can stably and reliably avoid interference between the cabinet 100 and the door body 3.

[0111] The refrigerator of the present application adopts the structure of semi-embedded refrigerator, the box body 1 is installed in the cabinet 100, the refrigerator door is used to replace the door of the cabinet 100, the box body 1 is used to contain the inner container 2, the inner side wall of the inner container 2 defines the storage room 21, the door body 3 is closed to form the refrigeration and / or freezing part, the hinge 4 is installed on the box body 1 and the door body 3 is installed on the rotating shaft 45 of the hinge 4, so that the door body 3 can rotate relative to the box body 1 to realize the opening or closing of the storage room 21, during the rotation of the door body 3, because the distance from the axis of the hinge 4 to the first auxiliary line 33 is less than the distance from the axis to one side of the box body 1, no matter the distance between the box body 1 and the cabinet 100 is, it can be guaranteed that the door body 3 is always inside the box body 1 during the rotation, so that the door body 3 is avoided to contact with the cabinet 100. In addition, the distance between the box body 1 and the cabinet 100 is left to be 2mm to 3mm to leave installation allowance for the instability of the foaming process, so that the assembly of the box body 1 and the cabinet 100 is more stable, on this basis, the distance from the axis to the first auxiliary line 33 is set to be greater than the distance from the axis to one side of the box body 1 and not greater than 0.5mm, which avoids the interference between the door body 3 and the cabinet 100 during the rotation caused by the error in the production or assembly process.
