[0028] Figure 1 Is an isometric view of the refrigerator 100 in some embodiments of the present utility model. The refrigerator 100 generally may include a box body 200, a first door body 300, and a second door body 400. Among them, the first door body 300 is rotatably installed on the box body 200, the second door body 400 is rotatably installed on the box body 200, and the second door body 400 includes a main door body 410 defining an inner door compartment 414 and a secondary door body 430 for opening and closing the inner door compartment 414. The side of the second door body 400 away from the box body 200 protrudes from the first door body 300. "Protrude" means that the front surface of the second door body 400 is more forward than the front surface of the first door body 300.

[0029] The refrigerator 100 generally may include a box body 200 and a door body. For convenience of description, hereinafter Figure 1 the left door body is denoted as the first door body 300, and Figure 1 the right door body is denoted as the second door body 400. The first door body 300 is a conventional door body (a door body without an inner door compartment), and the second door body 400 is the refrigerator door 110 that the present invention wants to protect.

[0030] In some embodiments of the present utility model, as Figure 1 shown, the second door body 400 is thicker than the first door body 300, that is, the second door body 400 has a larger dimension in the front-rear direction compared with the first door body 300, so that the second door body 400 protrudes forward compared with the first door body 300. Because the thickness of the second door body 400 is increased, more storage space can be developed inside the second door body 400, thereby increasing the volume of the inner door compartment 414.

[0031] Those skilled in the art can understand that the front side of the box body 200 can be flat. The thickness of the second door body 400 is increased, which protrudes forward and further occupies the space on the front side of the refrigerator 100, without occupying the storage space inside the refrigerator 100, thereby increasing the storage space of the inner compartment 414 of the door. In the existing refrigerator 100, the door body is often very thick for the sake of integrity, occupying the usable space of the box body 200. However, the refrigerator 100 in this embodiment does not occupy the original storage space inside the box body 200 of the refrigerator 100, and the protruding space can accommodate more high-quality ingredients.

[0032] In some embodiments of the present invention, the secondary door body 430 is located on the front side of the first door body 300 to facilitate the opening and closing of the secondary door body 430.

[0033] In some embodiments of the present invention, the thickness of the part where the second door body 400 protrudes from the first door body 300 is selected from any value in the range of 0.5 cm to 10 cm. This can significantly increase the storage space of the inner compartment 414 of the door and solve the problem that the inner compartment 414 cannot accommodate a large amount of food or beverages.

[0034] In some embodiments of the present invention, the thickness of the part where the second door body 400 protrudes from the first door body 300 is selected from any value in the range of 1 cm to 4 cm. This can increase the volume of the inner compartment 414 of the door while ensuring the overall appearance of the refrigerator 100 is harmonious.

[0035] In some embodiments of the present invention, the refrigerator 100 is a side-by-side refrigerator, and the first door body 300 and the second door body 400 are arranged to open opposite to each other. This makes one side door body of the refrigerator 100 protrude forward more than the other side door body, increasing the volume of the inner compartment 414 in the second door body 400 while improving the overall aesthetics of the refrigerator 100.

[0036] In some embodiments of the present invention, the refrigerator 100 can be a double-layer refrigerator, with the upper layer being a refrigerating compartment and the lower layer being a freezing compartment. The first door body 300 and the second door body 400 can be arranged to open opposite to each other in the refrigerating compartment, and the first door body 300 and the second door body 400 can also be arranged to open opposite to each other in the lower freezing compartment.

[0037] As Figure 1 shown, the second door bodies 400 on the refrigerating compartment and the freezing compartment can be arranged on the same side. The second door body 400 can be arranged on the right side of the upper refrigerating compartment and the right side of the lower freezing compartment, and the first door body 300 can be arranged on the left side, making the right side of the entire refrigerator 100 protrude forward more than the left side, and the overall visual effect is also relatively harmonious.

[0038] Alternatively, a second door body 400 can be provided on the left side of the upper refrigerating compartment, a first door body 300 can be provided on the right side of the refrigerating compartment, a first door body 300 can be provided on the left side of the lower freezing compartment, and a second door body 400 can be provided on the right side of the freezing compartment, so that the protrusions on the upper and lower parts of the front side of the refrigerator 100 are staggered.

[0039] In some embodiments of the present utility model, the refrigerator 100 can further be provided with a sliding switch 500. The sliding switch 500 is provided on a side of the second door body 400 close to the first door body 300, and the sliding switch 500 is provided on a part of the second door body 400 that protrudes forward compared with the first door body 300, so that the sliding switch 500 is exposed, facilitating the user to touch the sliding switch 500.

[0040] Among them, the user can unlock the secondary door body 430 by sliding the sliding switch 500 upward. After the secondary door body 430 is closed, the secondary door body 430 will be automatically locked. It can also be set that the user unlocks the secondary door body 430 by sliding the sliding switch 500 downward. After the secondary door body 430 is closed, the secondary door body 430 will be automatically locked.

[0041] In some embodiments of the present utility model, a handle can be provided at the bottom of the secondary door body 430 for opening and closing the secondary door body 430, and the sliding switch 500 is provided on the upper side of the handle. Correspondingly, the sliding switch 500 can be set to be unlocked by sliding downward, which can facilitate unlocking the secondary door body 430. After the user unlocks the secondary door body 430 by sliding the sliding switch 500 downward, the user's hand can directly grasp the handle on the lower side of the sliding switch 500, so that the user's actions of unlocking the secondary door body 430 and grasping the handle can be completed in one go, and the design is more user-friendly.

[0042] In some other embodiments of the present utility model, the refrigerator 100 can also use a password lock to lock the secondary door body 430. The password lock needs to input a password to open, providing another convenient unlocking method. Multiple passwords can be set for the password lock, which is convenient for family members or employees to use. The password lock is suitable for environments where multiple people need to share the use of the refrigerator 100, such as families, offices, restaurants, etc.

[0043] In some other embodiments of the present utility model, the refrigerator 100 can also fix the secondary door body 430 to the main door body 410 by means of a buckle to prevent the secondary door body 430 from being accidentally opened. The buckle lock usually has a simple structure and low cost. The above locking method is applicable to some occasions where the safety requirements are not particularly high but it is necessary to prevent the door body from being accidentally opened, such as commercial freezers, refrigerated display cabinets, etc.

[0044] In some embodiments of the present utility model, Figure 2 is an axonometric view of the refrigerator door 110 in some embodiments of the present utility model.

[0045] as will be described later with reference to Figure 2 Figure 6 and take the second door body 400 as an example to describe the refrigerator door of the present invention in detail. A transparent panel 440 is provided on the second door body 400. The transparent panel 440 is provided on the secondary door body 430 and is arranged facing the front side of the refrigerator 100, so that the user can see the storage state of the items in the inner compartment 414 through the transparent panel 440 from the front side of the refrigerator 100.

[0046] In this embodiment, the transparent panel 440 can be arranged in the middle of the secondary door body 430, and the periphery of the transparent panel is fixed by surrounding the secondary door body 430. The transparent panel 440 can also be arranged only on the upper side part of the secondary door body 430 or only on the lower side part of the secondary door body 430. In addition, a transparent panel 440 can also be provided on the first door body 300, and the transparent panel 440 is arranged facing the front side of the refrigerator 100, so that the user can see the storage state of the items inside the refrigerator 100 through the transparent panel 440 from the front side of the refrigerator 100. The transparent panel 440 can be arranged only in the middle of the first door body 300, or only on the upper side and the lower side of the first door body 300.

[0047] In some embodiments of the present utility model, the transparent panel 440 can be made of polymethyl methacrylate (PMMA) material. Polymethyl methacrylate is also known as plexiglass or acrylic, with excellent transparency, good weather resistance and rigidity, and is commonly used in display devices. The transparent panel 440 can also be made of ordinary glass. Ordinary glass has good light transmittance and can clearly display the state of the items in the inner compartment 414.

[0048] In some embodiments of the present utility model, Figure 3 is an axonometric view of the refrigerator door 110 with the secondary door body hidden in some embodiments of the present utility model. The refrigerator 100 can also be provided with an operation panel 600. The operation panel 600 is arranged at the bottom of the inner compartment 414, below the drawer 450. The operation panel 600 can adjust the temperature inside the inner compartment 414, can also adjust the brightness of the light in the inner compartment 414, and can also adjust the operation mode of the inner compartment 414, such as whether to turn on the quick-cooling mode, etc.

[0049] In some embodiments of the present utility model, Figure 4 is an exploded view of the refrigerator door 110 in some embodiments of the present utility model. As Figures 3 to 4As shown, the refrigerator door 110 includes a main door body 410. An inner door compartment 414 is defined within the main door body 410. The inner door compartment 414 includes a quick-cooling zone 415. The quick-cooling zone 415 is configured with at least one quick-cooling inlet 4151 and at least one quick-cooling outlet 4152, such that cold air enters the quick-cooling zone 415 via the quick-cooling inlet 4151 and flows out of the quick-cooling zone 415 via the quick-cooling outlet 4152.

[0050] In this embodiment, the quick-cooling zone 415 refers to the area inside the inner door compartment 414 that can quickly cool the items stored therein. In summer, the quick-cooling zone 415 can quickly lower the temperature of beverages, enabling users to drink cold drinks as soon as possible and meeting the daily usage needs of users.

[0051] In some embodiments of the present utility model, the main door body 410 includes a partition member 416 disposed within the inner door compartment 414. The partition member 416 divides the quick-cooling zone 415 within the inner door compartment 414; the quick-cooling inlet 4151 and the quick-cooling outlet 4152 are formed on the partition member 416.

[0052] In this embodiment, by partitioning a smaller space within the already small inner door compartment 414, that is, by the partition member 416 partitioning the quick-cooling zone 415 within the inner door compartment 414, and arranging the quick-cooling inlet 4151 and the quick-cooling outlet 4152 in the quick-cooling zone 415 partitioned by the partition member 416.

[0053] In this embodiment, the quick refrigeration and freezing function of the quick-cooling zone 415 is thus achieved. Since the quick-cooling inlet 4151 is provided in the quick-cooling zone 415, the items placed in the quick-cooling zone 415 are closest to the quick-cooling inlet 4151, and the cold air blown out from the quick-cooling inlet 4151 can directly blow on the items stored in the quick-cooling zone 415, thereby directly cooling the items stored in the quick-cooling zone 415. Secondly, since the volume of the inner door compartment 414 is already relatively small, and the quick-cooling zone 415 is a smaller area within the inner door compartment 414, the smaller area can more easily reduce the temperature of this area, thus achieving quick refrigeration in this area.

[0054] Figure 5 It is an axonometric view of the return-shaped frame 416 in the refrigerator door 110 in some embodiments of the present utility model. In some embodiments of the present utility model, the partition member 416 is a return-shaped frame, and the quick-cooling inlet 4151 and the quick-cooling outlet 4152 are relatively disposed on both sides of the return-shaped frame. The return-shaped frame 416 is surrounded by four plates, and both the front and rear sides are hollow. The return-shaped frame 416 and the rear side wall of the inner door compartment 414 jointly define the quick-cooling zone 415.

[0055] In some other embodiments of the present utility model, a quick-cooling area 415 can also be separated in the inner compartment 414 of the door by a partition plate, or a quick-cooling box can be provided in the inner compartment 414 of the door to separate the quick-cooling area 415.

[0056] Figure 6 FIG. 4 is a schematic diagram of the air duct of the refrigerator door 110 in some embodiments of the present utility model. In some embodiments of the present utility model, a gap 413 is provided between the left and right sides of the return-shaped frame and the peripheral wall of the inner compartment 414 of the door. The quick-cooling inlet 4151 and the quick-cooling outlet 4152 are oppositely arranged on the left and right sides of the return-shaped frame; the main door body 410 is provided with an air inlet 411 and an air outlet 412 communicating with the inner compartment 414 of the door, so that the cold air of the refrigerator 100 enters the inner compartment 414 of the door through the air inlet 411, flows through the gap 413, and flows out of the inner compartment 414 through the air outlet 412.

[0057] In some embodiments of the present utility model, the quick-cooling inlet 4151 and the quick-cooling outlet 4152 are respectively strip-shaped holes extending in the front and rear directions.

[0058] In some embodiments of the present utility model, there are at least two quick-cooling inlets 4151, and they are distributed in the vertical direction. There are at least two quick-cooling outlets 4152, and they are distributed in the vertical direction; moreover, the quick-cooling inlets 4151 and the quick-cooling outlets 4152 are in one-to-one correspondence in the horizontal direction.

[0059] In some embodiments of the present utility model, the main door body 410 further includes at least one drawer 450 installed in the quick-cooling area 415; at least one quick-cooling inlet 4151 and at least one quick-cooling outlet 4152 respectively correspond to the upper side of each drawer 450, and the distance between the quick-cooling inlet 4151 and the quick-cooling outlet 4152 and their corresponding drawers 450 is less than 5 cm. In this way, by reducing the distance from the quick-cooling outlet 4152 to the drawer 450, the quick-cooling effect can be improved.

[0060] In some embodiments of the present utility model, the distance between the quick-cooling inlet 4151 and the quick-cooling outlet 4152 and their corresponding drawers 450 is less than 1 cm.

[0061] In some embodiments of the present utility model, at least one of the left side wall 417 and the right side wall 419 of the inner compartment 414 of the door is provided with a lamp groove 420. The lamp groove 420 is a groove recessed inward from the wall surface on the left side wall 417 or the right side wall 419, so that the light source 421 can be arranged in the lamp groove 420. Since the volume of the inner compartment 414 of the door is relatively limited, setting the lamp groove 420 to install the light source 421 can effectively save the space inside the inner compartment 414 of the door, thereby indirectly increasing the volume of the inner compartment 414 of the door.

[0062] In this embodiment, the lamp slot 420 is configured with adjacent first wall surface 4201 and second wall surface 4202. The first wall surface 4201 inclines from back to front towards the middle of the inner compartment 414 of the door, and the second wall surface 4202 inclines from front to back towards the middle of the inner compartment 414 of the door. At least one light source 421 is disposed in the lamp slot 420 so that the light source 421 illuminates the inner compartment of the door by means of the reflection of the first wall surface 4201 and the second wall surface 4202.

[0063] In some embodiments of the present utility model, the included angle between the first wall surface 4201 and the rear side wall of the inner compartment 414 of the door is smaller than the included angle between the second wall surface 4202 and the rear side wall of the inner compartment 414 of the door.

[0064] In some embodiments of the present utility model, the included angle between the first wall surface 4201 and the rear side wall of the inner compartment 414 of the door ranges from 35 degrees to 55 degrees. The included angle between the first wall surface 4201 and the rear side wall of the inner compartment 414 of the door is an acute angle, and the first wall surface 4201 faces the rear side wall of the inner compartment 414, so that the light source 421 disposed on the first wall surface 4201 shines light towards the rear side of the inner compartment 414 of the door.

[0065] In this embodiment, since the rear part of the inner compartment 414 of the door is at the innermost part of the inner compartment 414 of the door, the light here is relatively dim. By setting the included angle between the first wall surface 4201 and the rear side wall of the inner compartment 414 of the door to a suitable angle, the rear area of the inner compartment 414 of the door can be effectively illuminated, thereby improving the overall lighting effect inside the inner compartment 414 of the door.

[0066] In some embodiments of the present utility model, the included angle between the second wall surface 4202 and the rear side wall of the inner compartment 414 of the door ranges from 80 degrees to 120 degrees, which can effectively illuminate the rear area of the inner compartment 414 of the door, thereby further improving the overall lighting effect inside the inner compartment 414 of the door.

[0067] In some embodiments of the present utility model, the ratio of the included angle between the first wall surface 4201 and the rear side wall of the inner compartment 414 of the door to the included angle between the second wall surface 4202 and the rear side wall of the inner compartment 414 of the door is between 0.2 and 0.6.

[0068] In some embodiments of the present utility model, the light source 421 is disposed on the first wall surface 4201, and a reflective coating 422 is disposed on the second wall surface 4202. By only disposing the light source 421 on the first wall surface 4201, the reflective coating 422 on the second wall surface 4202 can reflect the light of the light source 421 installed on the first wall surface, thereby illuminating the direction towards which the reflective coating 422 faces, saving the number of light sources 421 used, and at the same time being able to ensure the lighting effect of the inner compartment 414 of the door.

[0069] In some other embodiments of the present utility model, the light source 421 may also be disposed on the second wall surface 4202, and the light source 421 irradiates toward the front side of the inner compartment 414 of the door. A reflective coating 422 is provided on the first wall surface 4201. The light source 421 may also be disposed on both the first wall surface 4201 and the second wall surface 4202 simultaneously, and the reflective coating 422 may also be provided on both the first wall surface 4201 and the second wall surface 4202. In this way, the reflective coating 422 can reflect the light irradiated by the light sources 421 mounted on the first wall surface 4201 and the second wall surface 4202 toward the wall surface side, so that the illumination brightness of the inner compartment 414 of the door can be greatly improved.

[0070] In some embodiments of the present utility model, the lamp slot 420 is disposed at the front part of the inner compartment 414 of the door. The distance between the front end of the inner compartment 414 and the lamp slot 420 is denoted as L1, and the distance between the rear end of the inner compartment 414 and the lamp slot 420 is denoted as L2. L1 / L2 = β, and β is selected from [1.5, 4.5].

[0071] In this embodiment, it is convenient to install the light source 421 during processing. If the lamp slot 420 is too close to the rear side of the inner compartment 414 of the door, it is not convenient to install the light source 421. Disposing the lamp slot 420 close to the front part of the inner compartment 414 also helps to hide the lamp slot 420. Looking at the inner compartment 414 from the front side of the refrigerator 100, the lamp slot 420 can be blocked by a part of the secondary door body 430, so that the existence of the lamp slot 420 is not easily seen from the front side of the refrigerator 100, and to a certain extent, the aesthetics of the refrigerator 100 or the door body can be improved.

[0072] In some embodiments of the present utility model, a plurality of longitudinal light sources 421 are provided on the left and right side walls 419 of the inner compartment 414 of the door, and a surface light source is completely covered and disposed on the rear side wall of the inner compartment 414. The longitudinal light source 421 is a light source 421 extending along the longitudinal direction of the main door body 410, which can provide uniform and sufficient illumination, enabling users to clearly see all the items inside the refrigerator 100, especially at night or in a relatively dark environment. The surface light source can create soft and uniform light, adding a warm atmosphere to the internal space of the refrigerator 100. At the same time, the backlight design can directly outline the contours of the items, enhancing the sense of spatial hierarchy and improving the user's visual experience.

[0073] In some other embodiments of the present utility model, there may also be multiple surface light sources, and the multiple surface light sources are dispersedly arranged on the rear side wall of the inner compartment 414.

[0074] In some embodiments of the present utility model, the longitudinal light source 421 may be an LED light source. The LED light source has the characteristics of high efficiency and energy saving, which can significantly reduce the energy consumption of the refrigerator 100. At the same time, the service life of the LED lamp is much longer than that of traditional lighting devices, reducing the frequency of replacing the light bulb and bringing convenience to users.

[0075] In some other embodiments of the present utility model, the light source 421 can also be arranged on the top wall of the inner compartment 414 of the door, or the light source 421 can be arranged at the junction of two adjacent side walls. For example, at the junction of the left side wall 417 and the rear side wall, or at the junction of the left side wall 417 and the top wall. Since the light source 421 is located at the junction, the light can radiate in two directions simultaneously, reducing the lighting blind area and making the light distribution in the lighting area more uniform.

[0076] In some other embodiments of the present utility model, arranging the light source 421 at the junction of two side walls can effectively reduce the shadows caused by object occlusion and improve the overall brightness of the space. Through a carefully designed lighting layout, a unique visual effect, such as a gradient effect, a sense of hierarchy, etc., can be created at the junction, thereby creating different atmospheres such as warm, romantic or modern. A reasonable lighting arrangement can expand or shrink the sense of space. By arranging the light source 421 at the junction, the reflection and refraction of light can be utilized to enhance the three-dimensional sense and the sense of hierarchy of the space.

[0077] In some embodiments of the present utility model, a plurality of lamp slots 420 arranged at intervals in the vertical direction are respectively provided on the left side wall 417 and the right side wall 419 of the inner compartment 414 of the door, and a longitudinal light source 421 is respectively arranged in each lamp slot 420.

[0078] In some embodiments of the present utility model, the refrigerator 100 can include a cabinet 200 and the refrigerator door 110 according to any one of the above.

[0079] In some embodiments of the present utility model, by protruding the side of the second door body 400 away from the cabinet 200 beyond the first door body 300, the volume of the inner compartment 414 in the second door body 400 is increased. In addition, the first impression given by the appearance is also very special, and the memory point is very prominent.

[0080] The refrigerator door 110 provided in some embodiments of the present utility model does not occupy the original storage space inside the cabinet 200 of the refrigerator 100. The protruding space can accommodate more high-quality ingredients. The large transparent panel 440 and the reasonable partition storage design can allow the user to understand the general storage state of the refrigerator 100 without opening the refrigerator door 110. The protruding display door body emphasizes display, which not only meets the user's usage needs but also meets the user's social psychological needs. This is a combined design concept.
