DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described embodiments are only part of the embodiments of the present embodiment, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] In the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0045] Refrigerators are common household appliances in people's lives. Refrigerators mainly store food or other items by maintaining a constant low temperature and cold state. With the development of technology, refrigerator styles are becoming more and more diverse. Taking the refrigerator door opening method as a reference, today's refrigerators include a variety of styles such as central doors, double doors, cross doors, French doors, etc. Which style of refrigerator has a reasonable layout and high space utilization is the key to improving product competitiveness and attracting consumers to buy.

[0046] In the related art, French-style multi-door refrigerators have a large horizontal space, a reasonable layout, and a high space utilization rate, which have won the favor of many consumers. Generally, the freezer compartment of a French-style multi-door refrigerator is composed of multiple layers of drawer doors, and a middle beam is arranged between two adjacent layers of drawer doors to achieve the sealing of the refrigerator body after the drawer doors are closed. However, since the drawer doors are moving parts, they need to avoid the middle beam during the process of pulling out or pushing in to avoid movement interference, so the area in the freezer compartment behind the middle beam cannot be used, resulting in space waste.

[0047] like Figure 1 A schematic diagram of the internal structure of a French multi-door refrigerator in the related art is shown, and the French multi-door refrigerator 1 includes a cabinet 1a, an upper drawer 1b, a lower drawer 1c and a center beam 1d. The cabinet 1a has a freezer cavity 1e, and the upper drawer 1b and the lower drawer 1c are respectively slidably loaded into the freezer cavity 1e, and the center beam 1d is arranged between two adjacent drawers and fixed to the cabinet 1a. After the two drawers are pushed into the cabinet 1a, the center beam 1d cooperates with the two drawers to achieve the sealing of the freezer cavity 1e of the cabinet 1a. However, since the center beam 1d is laterally arranged on the opening side of the freezer cavity 1e to form a blockage, the upper drawer 1b and the lower drawer 1c need to avoid the center beam 1d when pushing or pulling out the freezer cavity 1e, thereby forming a vacant area 1f (refer to Figure 1 For a French-style multi-door refrigerator, the vacant area 1f occupies at least 10% of the total space of the freezing chamber 1e, which results in the actual available space in an ordinary French-style multi-door refrigerator being far less than the nominal capacity of the refrigerator.

[0048] Refer to the following Figure 2 and Figure 3 The utility model provides a refrigerator 10, including a box assembly 11, a compressor 12, a condenser 13, an evaporator 14 and a throttling element (not shown in the figure). The compressor 12, the condenser 13, the evaporator 14 and the throttling element are respectively arranged in the box assembly 11, the box assembly 11 is provided with a freezing chamber 11a and a refrigerating chamber 11b, and at least part of the evaporator 14 is arranged in the freezing chamber 11a.

[0049] When the refrigerator 10 is in operation, the compressor 12 outputs a high-temperature and high-pressure gaseous refrigerant to the condenser 13, and the high-temperature and high-pressure gaseous refrigerant is condensed into a medium-temperature and high-pressure refrigerant through the condenser 13. The medium-temperature and high-pressure refrigerant undergoes the expansion and throttling effect of the throttling element, so that the pressure and temperature of the refrigerant are further reduced, and a low-temperature and low-pressure liquid refrigerant flows out of the throttling element to the evaporator 14. The low-temperature and low-pressure liquid refrigerant evaporates into a gaseous refrigerant in the evaporator 14. At least part of the evaporator 14 is arranged in the freezing chamber 11a, so that the refrigerant absorbs a large amount of heat in the freezing chamber 11a during the evaporation process, thereby reducing the temperature in the freezing chamber 11a, making it easier to use the freezing chamber 11a to freeze items and realize the refrigeration of the refrigerator 10. The refrigerant coming out of the evaporator 14 is replenished back to the compressor 12 to form a refrigerant circuit. In this way, the refrigerant circulates continuously in the refrigerant circuit to maintain the freezing environment of the freezing chamber 11a (for example, less than -1°C).

[0050] like Figure 3 As shown, an air duct 11c is provided between the refrigerating compartment 11b and the freezing compartment 11a, so as to transport part of the cold air from the freezing compartment 11a to the refrigerating compartment 11b through the air duct 11c, so as to reduce or maintain the low temperature environment of the refrigerating compartment 11b (eg, 2°C to 8°C).

[0051] See you later Figure 2 , for the freezer compartment 11a of the refrigerator 10, a large number of items are usually stored as reserves. In order to make it easier for users to access the items in the freezer compartment 11a without entering the depths of the freezer compartment 11a to find the required items, the freezer compartment 11a of the refrigerator 10 is assembled with multiple drawers 11d to form multiple independent storage spaces, which is convenient for users to classify and store items, and can also reduce the mixing and adhesion of food. At the same time, by storing items in separate drawers 11d, each time a drawer 11d is opened, only a part of the freezer space is exposed to the outside air, which can reduce cold air leakage, help save energy and keep the temperature in the freezer compartment 11a stable.

[0052] Since the compressor 12 and other equipment are usually installed at the rear of the box assembly 11, they will inevitably occupy the storage space of the freezer 11a. In order to increase the volume of the freezer 11a and reasonably utilize the vacant area at the rear of the center beam between two adjacent drawers 11d, the utility model also provides a box assembly 100, which can reasonably utilize the vacant area to improve the space utilization rate of the freezer 11a in the refrigerator 10.

[0053] The box assembly 100 provided by the present invention will be described below.

[0054] See also Figures 4 to 6The box assembly 100 includes a box 110, at least one set of support beams, and at least three drawers 140. The box 110 has a storage cavity 111, and the storage cavity 111 has an open end 112. The box 110 includes a first side wall 113 and a second side wall 114 that are oppositely arranged. The at least one set of support beams includes a first support beam 120 and a second support beam 130. The first support beam 120 is arranged on a side of the first side wall 113 located at the open end 112, and the second support beam 130 is arranged on a side of the second side wall 114 located at the open end 112, and the first support beam 120 and the second support beam 130 are arranged opposite to each other. At least three drawers 140 include a first drawer 141, a second drawer 142 and a third drawer 143 which can be moved relative to the box body 110 to enter and exit the storage cavity 111, and the first drawer 141 and the second drawer 142 are stacked in the storage cavity 111 along the height direction of the box body 110, and the first support beam 120 and the second support beam 130 are respectively abutted between the first drawer 141 and the second drawer 142, and the third drawer 143 is placed between the first support beam 120 and the second support beam 130 to seal the storage cavity 111.

[0055] It should be noted that the box body 110 includes a shell, an inner liner 110a and an insulation layer 110c filled between the shell and the inner liner 110a. The inner wall of the storage cavity 111 is formed by the inner liner 110a, and the outer wall of the storage cavity 111 is formed by the shell. The insulation layer 110c can be made of foam material, and the insulation layer 110c is used to reduce the heat exchange between the storage cavity 111 and the outside world.

[0056] The first side wall 113 and the second side wall 114 of the box body 110 may be provided with a plurality of groups of support beams, and the first support beam 120 and the second support beam 130 of each group of support beams are respectively provided opposite to each other. Figure 5 As shown, taking the box body 110 provided with a group of support beams as an example, the first support beam 120 and the second support beam 130 can divide the storage cavity 111 of the box body 110 into three storage spaces, the part located above the first support beam 120 and the second support beam 130 is the first storage space 111a, the part located below the first support beam 120 and the second support beam 130 is the second storage space 111b, and the part located between the first support beam 120 and the second support beam 130 is the third storage space 111c.

[0057] When the box assembly 100 is in use, the first drawer 141 is slidably disposed in the first storage space 111a, the second drawer 142 is slidably disposed in the second storage space 111b, and the third drawer 143 is slidably disposed in the third storage space 111c. The three drawers can be moved independently relative to the box 110 to enter and exit the storage cavity 111. When the three drawers are placed in the storage cavity 111 at the same time, the third drawer 143 is used to seal the gap between the first drawer 141 and the second drawer 142 together with the first support beam 120 and the second support beam 130 on both sides thereof to achieve sealing of the storage cavity 111. When the third drawer 143 is pulled out of the storage cavity 111, the first support beam 120 and the second support beam 130 can still be supported between the first drawer 141 and the second drawer 142.

[0058] Compared with the vacant area behind the middle beam mentioned in the related art that cannot be fully utilized, the box assembly 100100 provided by the utility model is provided with a first support beam 120 and a second support beam 130 on the first side wall 113 and the second side wall 114 respectively, and an opening is reserved between the first support beam 120 and the second support beam 130, so as to form a third storage space 111c connected to the outside of the box 110 between the first support beam 120 and the second support beam 130. It is equivalent to that the utility model replaces the original vacant area with the third storage space 111c. At the same time, the utility model uses the third drawer 143 to fill the third storage space 111c, so that the gap between the first drawer 141 and the second drawer 142 is sealed by the third drawer 143 and the first support beam 120 and the second support beam 130 on both sides thereof, so as to prevent the freezer compartment of the box 110 from leaking cold. Furthermore, the third drawer 143 serves as an independent storage space, which can be directly pulled out or pushed in relative to the storage cavity without avoiding the middle beam mentioned in the related art, thereby achieving full utilization of the vacant area behind the middle beam, increasing the storage space of the refrigerator freezer, and improving the space utilization rate of the freezer in the refrigerator.

[0059] In some embodiments, in order to make the position where the support beam is provided in the refrigerator flat and beautiful in appearance, the outer walls of at least three drawers 140 located at the opening end 112 are coplanar, and the outer walls of the first support beam 120 and the second support beam 130 located at the opening end 112 are coplanar with the outer wall of the third drawer 143 located at the opening end 112. That is, on the side of the box body 110 where the opening end 112 is provided, each drawer and the two support beams are in the same plane, which can ensure the appearance of the refrigerator to be flat and beautiful and avoid hygienic dead corners, and can also improve the safety of use and avoid users bumping into the sharp parts of the refrigerator appearance.

[0060] In some embodiments, in order to make the left and right sides of the refrigerator look flat and facilitate embedded installation of the refrigerator, the wall surfaces of the first drawer 141 and the second drawer 142 located on the first side wall 113 are respectively coplanar with the wall surface of the first support beam 120 located on the first side wall 113, and the wall surfaces of the first drawer 141 and the second drawer 142 located on the second side wall 114 are respectively coplanar with the wall surface of the second support beam 130 located on the second side wall 114.

[0061] like Figure 6 As shown, in some embodiments, in order to facilitate the setting of support beams on both side walls of the box body 110, the first side wall 113 is located on one side of the opening end 112 and has at least two first grooves 113a arranged at intervals along the height direction of the box body 110, and the interval between the two first grooves 113a forms a first support beam 120; the second side wall 114 is located on one side of the opening end 112 and has at least two second grooves 114a arranged at intervals along the height direction of the box body 110, and the interval between the two second grooves 114a forms a second support beam 130.

[0062] It should be noted that the first support beam 120 and the first side wall 113 are integrally formed, and the second support beam 130 and the second side wall 114 are integrally formed. On the one hand, the structural strength between each support beam and the side wall of the box body 110 can be improved, which is beneficial for each support beam to provide support for the first drawer 141. On the other hand, the sealing between each support beam and the side wall of the box body 110 can be improved, and the amount of cold leakage in the freezer compartment of the box body 110 can be reduced.

[0063] Of course, in other embodiments, the first support beam 120 and the first side wall 113 may be integrally formed, and the second support beam 130 and the second side wall 114 may be integrally formed.

[0064] like Figure 6 As shown, in some embodiments, in order to ensure the sealing of the storage cavity 111 of the box body 110 and reduce the leakage of cold in the refrigerator, the first support beam 120 includes a first connection portion 121 and a second connection portion 122 arranged at intervals along the height direction of the box body 110, and a third connection portion 123 disposed between the first connection portion 121 and the second connection portion 122. The second support beam 130 includes a fourth connection portion 131 and a fifth connection portion 132 arranged at intervals along the height direction of the box body 110, and a sixth connection portion 133 disposed between the fourth connection portion 131 and the fifth connection portion 132, and the third connection portion 123 is disposed opposite to the sixth connection portion 133. The first drawer 141 abuts against the first connection portion 121 and the fourth connection portion 131, respectively, the second drawer 142 abuts against the second connection portion 122 and the fifth connection portion 132, respectively, and the third drawer 143 abuts against the third connection portion 123 and the sixth connection portion 133, respectively.

[0065] Continue to refer Figure 6In some embodiments, in order to facilitate the first drawer 141 to be pushed in and pulled out from the storage cavity 111, a first arc portion 124 is provided at the connection between the first connection portion 121 and the first side wall 113, and a second arc portion 125 is provided at the connection between the fourth connection portion 131 and the second side wall 114. The first drawer 141 includes a first box body 141a slidably connected to the inner wall of the storage cavity 111 and a first door body 141b fixed to the first box body 141a. The first door body 141b is located at one side of the first side wall 113 and is respectively in contact with the first side wall 113, the first arc portion 124 and the first connection portion 121. The first door body 141b is located at one side of the second side wall 114 and is respectively in contact with the second side wall 114, the second arc portion 125 and the fourth connection portion 131.

[0066] It should be noted that the first arc portion 124 and the second arc portion 125 can buffer the force of the first drawer 141 colliding with the box body 110 when the user pushes the first drawer 141 into the storage cavity 111, so that the movement of the first drawer 141 is smooth and soft, avoiding damage to the first drawer 141 due to excessive force when the user closes the first drawer 141, and at the same time reducing the sound of the first drawer 141 being pushed closed.

[0067] At the same time, the first arc portion 124 and the second arc portion 125 can increase the contact area between the first door body 141b of the first drawer 141 and the cabinet 110, thereby improving the sealing performance of the cabinet 110 and reducing the cold leakage of the refrigerator.

[0068] In addition, the first arc-shaped portion 124 can also facilitate processing to form the first support beam 120 on the first side wall 113 , and the second arc-shaped portion 125 can also facilitate processing to form the second support beam 130 on the second side wall 114 .

[0069] Accordingly, in some embodiments, in order to facilitate pushing and pulling the second drawer 142 from the storage cavity 111, a third arc portion is provided at the connection between the second connecting portion 122 and the first side wall 113, and a fourth arc portion is provided at the connection between the fifth connecting portion 132 and the second side wall 114; the second drawer 142 includes a second box body 142a slidably connected to the inner wall of the storage cavity 111 and a second door body 142b fixed to the second box body 142a, the second door body 142b is located on one side of the first side wall 113 and is respectively fitted with the first side wall 113, the third arc portion and the second connecting portion 122, and the second door body 142b is located on one side of the second side wall 114 and is respectively fitted with the second side wall 114, the fourth arc portion and the fifth connecting portion 132.

[0070] refer to Figure 7 and Figure 8 In some embodiments, in order to meet the installation requirements of refrigerators in spaces of different sizes, the first support beam 120 and the second support beam 130 may extend in different directions relative to the box body 110. The following examples illustrate:

[0071] refer to Figure 7 As one example, the first support beam 120 and the second support beam 130 extend along the depth direction of the storage cavity 111 , respectively, and the first support beam 120 and the second support beam 130 extend outside the storage cavity 111 , respectively.

[0072] It should be noted that refrigerators are usually installed in an embedded manner, and the space reserved on the left and right sides of the refrigerator is relatively small, while the space reserved on the front and back sides of the refrigerator is relatively large, that is, the length dimension of the refrigerator is relatively high, and the width dimension of the refrigerator is relatively tolerant. The utility model sets the side of the box body 110 with the open end 112 as the front side of the refrigerator, and the side wall of the box body 110 opposite to the open end 112 is the rear side of the refrigerator, then the first support beam 120 and the second support beam 130 extend in the direction from the rear side of the refrigerator to the front side, respectively, so that the first support beam 120 protrudes from the first side wall 113, and the second support beam 130 protrudes from the second side wall 114, which is equivalent to realizing the support effect of the first support beam 120 and the second support beam 130 on the drawer and the sealing effect on the storage cavity 111 without changing the length dimension of the refrigerator.

[0073] refer to Figure 8 As one example, the first support beam 120 can also extend in the direction from the first side wall 113 to the second side wall 114, and the second support beam 130 can also extend in the direction from the second side wall 114 to the first side wall 113, and the first support beam 120 and the second support beam 130 are respectively placed in the storage cavity 111.

[0074] It should be noted that when the reserved spaces on the front and rear sides of the refrigerator also have installation requirements (i.e., when there are requirements for the width installation space of the refrigerator), the first support beam 120 and the second support beam 130 can be extended in the length direction of the refrigerator to meet the installation and use requirements. In addition, to avoid the first support beam 120 and the second support beam 130 interfering with the movement of the third drawer 143 at this time, the first support beam 120 can extend along the end of the first side wall 113 close to the rear side of the refrigerator to the end of the first side wall 113 close to the front side of the refrigerator, and the second support beam 130 can extend along the end of the second side wall 114 close to the rear side of the refrigerator to the end of the second side wall 114 close to the front side of the refrigerator. At this time, in order to facilitate directly pulling the third drawer 143 out of or pushing it into the storage cavity 111, a set of slide rails can be installed between the side of the third drawer 143 close to the first support beam 120 and the first support beam 120, and another set of slide rails can be installed between the side of the third drawer 143 close to the second support beam 130 and the second support beam 130 to achieve flexible pushing and pulling of the third drawer 143 and avoid movement interference between the third drawer 143 and the two support beams.

[0075] refer to Fig. 9In some embodiments, in order to further improve the sealing of the storage cavity 111 of the cabinet 110 and reduce the cold leakage of the refrigerator, the cabinet assembly 100100 also includes a seal, which includes at least a first door seal 151 and a second door seal 152. The first door seal 151 is fixed to the first door body 141b along the circumference of the first door body 141b, and the second door seal 152 is fixed to the second door body 142b along the circumference of the second door body 142b, so as to seal the gap between each drawer and the cabinet 110 through multiple door seals.

[0076] It should be noted that when the joint between the first door body 141b and the first curved portion 124 is set to be an arc shape, the first door seal 151 can also be set to be an arc shape along the curvature of the first door body 141b to facilitate better sealing.

[0077] In some embodiments, to further improve the sealing of the storage cavity 111 of the box body 110, the seal may also include a third door seal and a fourth door seal. The third door seal is arranged between the third drawer 143 and the first support beam 120, and the fourth door seal is arranged between the third drawer 143 and the second support beam 130.

[0078] refer to Figures 7 to 9 In some embodiments, in order to facilitate the third drawer 143 to be smoothly pulled out or pushed into the storage cavity 111, the third drawer 143 includes a third box body 143a slidably connected to the inner wall of the storage cavity 111 and a third door body 143b fixed to the third box body 143a, the third box body 143a is located on one side of the first side wall 113 and is provided with a first slide rail 160, the inner wall of the first side wall 113 is provided with a second slide rail 170 that cooperates with the first slide rail 160, the third box body 143a is located on one side of the second side wall 114 and is provided with a third slide rail 180, the inner wall of the second side wall 114 is provided with a fourth slide rail 190 that cooperates with the third slide rail 180, and each slide rail extends along the depth direction of the storage cavity 111 respectively.

[0079] It should be noted that the slide rails may include various types such as suspension slide rails, track slide rails, ball bearing slide rails, etc., and the present utility model does not impose any limitation thereto.

[0080] Of course, a slide rail assembly may also be provided between the first drawer 141 and the second drawer 142 and the box body 110 so that the user can pull out or push in. In addition, each drawer may also be opened and closed by a variety of cooperation modes such as rollers and slideways, and the present invention is not limited thereto.

[0081] In some embodiments, to ensure the stability of the third drawer 143 when being pulled out and pushed into the storage cavity 111, the first slide rail 160 includes two first rail portions spaced apart at the third box body 143a along the height direction of the box body 110, and the second slide rail 170 is slidably connected between the two first rail portions. The third slide rail 180 includes two second rail portions 181 spaced apart at the third box body 143a along the height direction of the box body 110, and the fourth slide rail is slidably connected between the two second rail portions 181.

[0082] It should be noted that at this time, a slide groove is formed between the two first rail parts, and the second slide rail 170 is embedded in the slide groove. When the user pulls the third drawer 143, the two first rail parts limit the second slide rail 170, which can prevent the third drawer 143 from derailing, shaking, tilting and other problems during movement, thereby ensuring the smooth movement of the third drawer 143 and improving the user experience.

[0083] In some embodiments, to improve the portability of the third drawer 143 and facilitate the user to pull, each slide rail can be respectively set to a hollow structure, a hollow structure, etc. For example, the first track portion and the second track portion 181 can also be set to an annular structure, such as a rectangular ring, an elliptical ring, etc., which is not limited by the present invention.
