Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and more particularly to a refrigerator. Background Technology

[0002] Refrigerators are common household appliances used to store everyday food. As people's living standards improve, their demands for refrigerator functionality are also increasing. Some refrigerators now feature illuminated doors.

[0003] In related technologies, a light source is installed on the inner side of the door panel so that a portion of the panel can emit light, serving both as illumination and a display of operating status to enhance the user experience. An embedded box is installed between the light source and the inner door liner to separate the door's insulation structure from the light source. However, the sealing structure of the embedded box is complex, affecting assembly efficiency. Utility Model Content

[0004] This application provides a refrigerator that simplifies the sealing structure of the embedded box.

[0005] In a first aspect, embodiments of this application provide a refrigerator, which includes:

[0006] The box-shaped structure forms a storage compartment with an opening at the front.

[0007] A door, connected to the housing, for opening or closing the storage compartment; the door includes:

[0008] A door panel, at least a portion of which is translucent;

[0009] The door inner liner is disposed at intervals and opposite to each other on the inner side of the door panel;

[0010] The door outer frame is located at the edge between the door panel and the door inner liner; the door outer frame includes:

[0011] The lower end cover is located at the bottom of the door panel and the inner door liner;

[0012] A side door frame is provided on the side of the door panel and the door liner;

[0013] A light source assembly is disposed between the door panel and the door liner; the light source assembly includes:

[0014] A surface light source is provided, fitted to the light-transmitting area of ​​the door panel;

[0015] The embedded box has its bottom end in contact with and abut against the lower end cover on an inclined surface, and the embedded box also contacts and abuts against the side door frame surface; the top end of the embedded box is respectively engaged with the side door frame and the lower end cover.

[0016] The refrigerator of this embodiment has a light source assembly installed inside its door, allowing the light-transmitting area of ​​the door panel to emit light. The light source assembly uses a pre-embedded box to separate the surface light source from the insulation structure inside the door. The pre-embedded box makes beveled contact and abuts against the lower end cover of the door frame, and also makes surface contact and abuts against the side door frame. This surface contact achieves a sealed design of the pre-embedded box, reducing the possibility of the insulation structure seeping into the surface light source. The pre-embedded box's position is fixed by its snap-fit ​​connection with the side door frame and the lower end cover. This connection method is simple, reliable, and improves assembly efficiency. Furthermore, the beveled contact between the bottom end of the pre-embedded box and the lower end cover provides a larger contact area, which improves the reliability of the seal.

[0017] In some embodiments of this application, the lower end cover is configured to form a limiting structure, the limiting structure is configured to form a limiting surface, the limiting surface abuts against the bottom end of the embedded box to restrict the degree of freedom of the embedded box downward along the height direction of the door.

[0018] In this embodiment of the application, a limiting structure is formed by constructing a limiting surface in the lower end cover to abut and limit the bottom end of the embedded box. The abutment structure is reliable and does not require other fixing structures, which helps to improve assembly efficiency.

[0019] In some embodiments of this application, the lower end cover forms a first inclined surface, and the first inclined surface contacts the surface of the embedded box.

[0020] The angle between the limiting surface of the limiting structure and the first inclined surface is an acute angle.

[0021] The limiting surface and the first inclined surface of this limiting structure form a V-shaped structure, which can restrict the downward position of the bottom of the embedded box and also restrict the degree of freedom of the embedded box along the thickness direction of the door.

[0022] In some embodiments of this application, the embedded box is located near the hinged side of the door body, forming a first contact surface and a second contact surface. The first contact surface and the second contact surface intersect and have an included angle. The first contact surface and the second contact surface respectively contact the side door frame and restrict the degree of freedom of the embedded box along the width and thickness directions of the door body.

[0023] Therefore, the embedded box, near the hinged side of the door, forms an intersecting first and second contact surface, which respectively contact the side door frame. This increases the contact area and improves sealing performance. The bent contact surface between the embedded box and the side door frame also increases the resistance to the flow path of the foaming material, further enhancing the sealing effect. Furthermore, the first and second contact surfaces simultaneously restrict the embedded box's degrees of freedom along both the width and thickness directions of the door, improving its positioning function.

[0024] In some embodiments of this application, the side door frame is provided with a first snap-fit ​​component;

[0025] The top of the pre-embedded box near the hinge side of the door is provided with a first buckle, and the first buckle is snapped into the first snap-fit ​​piece from top to bottom;

[0026] The top of the pre-embedded box on the hinged side away from the door body is provided with a second snap-fit ​​component;

[0027] The lower end cover is provided with a second buckle on its side, which is engaged with the second snap-fit ​​piece from top to bottom.

[0028] Therefore, in this embodiment of the application, the embedded box is connected to the side door frame by first buckles and first connecting pieces along both sides of the door width direction; the embedded box is connected to the side of the lower end cover by second buckles and second connecting pieces, improving the stability of the embedded box connection. Furthermore, both the first and second buckles engage from top to bottom, achieving connection and limiting without affecting the contact and surface contact between the bottom of the embedded box and the lower end cover.

[0029] In some embodiments of this application, the top of the pre-embedded box forms a first adhesive surface;

[0030] The lower end cover and the side door frame form a second adhesive surface, which is flush with the first adhesive surface; the door panel is bonded to the first adhesive surface and the second adhesive surface respectively.

[0031] By setting the first and second glue application surfaces to be flush, glue can be applied to the first and second glue application surfaces sequentially without adjusting the glue application parameters. This simplifies the glue application process and helps improve assembly efficiency.

[0032] In some embodiments of this application, the top of the pre-embedded box has an adhesive plate portion, and the adhesive plate portion forms the first adhesive surface on the side facing the door panel.

[0033] The adhesive plate portion forms protruding ribs, which are located at the bottom end of the first adhesive surface.

[0034] By forming protruding ribs at the bottom of the first adhesive surface, a barrier is provided for the adhesive, preventing excess adhesive from entering the installation area of ​​the surface light source.

[0035] In some embodiments of this application, the adhesive plate portion forms an adhesive groove, which is disposed near the top side of the rib.

[0036] The adhesive reservoir provides space for adhesive, further reducing the installation area for adhesive entering the surface light source.

[0037] In some embodiments of this application, the second adhesive application surface includes a first adhesive application area and a second adhesive application area, the edge of the side door frame forms the first adhesive application area, and the lower end cover forms the second adhesive application area; the adhesive application width of the second adhesive application area is smaller than the adhesive application width of the first adhesive application area.

[0038] The two ends of the first adhesive application surface are respectively opposite to the first adhesive application area, which is beneficial to use the two ends of the first adhesive application surface as the start and end of adhesive application.

[0039] The second adhesive application area is narrower to fit the compact structure of the lower cover; the first adhesive application area is wider to improve the reliability of door panel bonding and sealing.

[0040] Secondly, embodiments of this application provide a refrigerator, which includes:

[0041] The box-shaped structure forms a storage compartment with an opening at the front.

[0042] A door, connected to the housing, for opening or closing the storage compartment; the door includes:

[0043] A door panel, at least a portion of which is translucent;

[0044] The door inner liner is disposed at intervals and opposite to each other on the inner side of the door panel;

[0045] The outer frame of the door is located at the edge of the door panel and the inner liner of the door.

[0046] A light source assembly is disposed between the door panel and the door liner; the light source assembly includes:

[0047] A surface light source is provided, fitted to the light-transmitting area of ​​the door panel;

[0048] An embedded box is inserted into the outer frame of the door from top to bottom and engages with the outer frame; the two sides of the embedded box along the width direction of the door contact and limit the outer frame surface; the bottom end of the embedded box is conformally set with the lower end cap at the bottom of the outer frame to form a beveled contact.

[0049] In this embodiment, the embedded box contacts the outer frame surface of the door on both sides along the width direction of the door, thus sealing both sides of the embedded box along the width direction of the door. Furthermore, the bottom end of the embedded box is conformally designed to the lower end cap of the bottom end of the outer frame, ensuring a seal between the bottom end of the embedded box and the lower end cap, limiting the bottom end of the embedded box, and allowing the seal at the bottom end of the embedded box to be unrestricted by the hinge groove and handle on the lower end cap. This provides the possibility of setting a larger width for the embedded box, and consequently, the possibility of setting a wider surface light source. The embedded box is inserted into the outer frame from top to bottom and snaps into it, making assembly simple, easy to assemble and disassemble, and highly efficient. Moreover, the top-to-bottom installation method does not affect the surface contact of the embedded box along the width direction of the door, nor does it affect the inclined surface contact between the bottom end of the embedded box and the lower end cap.

Detailed Implementation

[0072] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0073] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0074] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0075] Some refrigerators have illuminated doors. For example, in French door or cross-door refrigerators, a surface light source is installed in the lower area of ​​the upper refrigerator door, forming a pattern on the door panel. This allows the door to display a certain luminous pattern, which can provide illumination, indicate working status, and improve the appearance.

[0076] An insulation layer is installed within the door body. To prevent the foam material from damaging the surface light source, a pre-embedded box is installed within the door body. The pre-embedded box needs to be sealed to the door panel, door frame, and lower end cover to prevent the foam material from entering the pre-embedded box. Due to the complex structure of the bottom of the lower end cover, which includes concealed handles, hinge grooves, and vent holes for the foam material, the sealing structure between the pre-embedded box and the lower end cover is also complex.

[0077] At the junction of the embedded box and the lower end cover, achieving a good seal is difficult due to the complex and varied shapes of the lower end cover. In related technologies, to simplify the sealing of the embedded box, the width of both the embedded box and the surface light source is relatively small to avoid the complex structure of the lower end cover and reduce the sealing area. However, this affects the size of the surface light source, thus impacting the lighting effect and aesthetic appearance.

[0078] Sealing the embedded box and panel with adhesive tape is not only costly in terms of materials, but also cumbersome and time-consuming.

[0079] In view of this, the present application embodiment utilizes the surface contact between the pre-embedded box and the door body to achieve sealing, and utilizes surface contact and snap-fit ​​to achieve position fixation. The sealing structure is simple, the assembly method is simple, and it is conducive to improving assembly efficiency.

[0080] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0081] Combination Figure 1 This application provides a refrigerator, which includes a cabinet 100. The cabinet 100 can be configured to form a storage compartment 101 with a front opening for storing items.

[0082] Multiple storage compartments can be provided to expand storage space. Depending on the storage temperature of the compartments, they can include at least one refrigerated compartment and at least one frozen compartment. The internal temperature of the refrigerated compartment can be maintained between approximately 0°C and 5°C for storing items in refrigerated mode; the internal temperature of the frozen compartment can be maintained between approximately -30°C and 0°C for storing items in frozen mode.

[0083] In some possible implementations, at least one of the storage compartments may also be configured as a vacuum chamber or a variable temperature chamber, etc., which will not be described in detail in the embodiments of this application.

[0084] For example, there may be two storage compartments, which may be stacked vertically or arranged side by side horizontally. One of them may be a refrigerator compartment and the other may be a freezer compartment.

[0085] The refrigerator in this embodiment may further include a refrigeration system for reducing the air temperature in the storage compartment. Exemplarily, the refrigeration system may be housed within the cabinet 100. The refrigeration system may include a compressor, condenser, expansion valve, and evaporator connected in a cycle.

[0086] During refrigeration system operation, the compressor compresses refrigerant vapor, generating high-temperature, high-pressure refrigerant vapor, and delivers it to the condenser. The condenser liquefies the high-temperature, high-pressure refrigerant vapor, generating high-temperature, low-pressure refrigerant liquid, which is then delivered to the expansion valve. The expansion valve reduces the pressure of the refrigerant liquid, transforming it from a high-pressure, low-temperature liquid into a low-pressure, low-temperature liquid, which is then delivered to the evaporator. The evaporator receives the low-pressure, low-temperature refrigerant liquid and boils it under isobaric conditions, absorbing heat and vaporizing to form refrigerant vapor, thereby lowering the temperature inside the storage compartment.

[0087] Continue to refer to Figure 1 The refrigerator in this embodiment may also include a door 200, which is rotatably connected to the cabinet 100 to open or close the storage compartment.

[0088] For example, the door 200 and the housing 100 are hinged together. Figure 2 The top and bottom ends of the door body 200 are provided with hinge grooves 201 for mounting hinges. The door body 200 has a width direction (corresponding to the attached...) Figure 2On both sides of the door body 200 (in the X-axis direction), one side is close to the hinge side of the door body 200, and the other side is away from the hinge side of the door body 200.

[0089] Each storage room 101 can be equipped with a corresponding door 200; or, as Figure 1 As shown, each storage room can be equipped with two doors 200, which can rotate in opposite directions to open or close the storage room.

[0090] In some embodiments of this application, a drawer 110 is provided inside the storage room, and the outer end of the drawer 110 is constructed to form a door, eliminating the need for an additional door. The drawer 110 is used to store food.

[0091] Recombined Figure 2 In some embodiments of this application, a handle portion 202 is also formed at the bottom end of the door body 200, and the handle portion 202 is located on one side of the hinge groove 201; the handle portion 202 is groove-shaped, which makes it convenient for the user to open and close the door from the bottom side.

[0092] Combination Figure 2 and Figure 3 In some embodiments of this application, the door 200 includes a door panel 210, at least a portion of which is light-transmitting, forming a light-transmitting area 211. The door panel 210 is located on the outer surface of the door 200 away from the housing 100, forming the appearance structure of the door 200. Exemplarily, the door panel 210 may be a glass panel.

[0093] The door body 200 may also include a door liner 220, which is spaced apart and opposite to each other on the inside of the door panel 210, with the door liner 220 facing the storage compartment. The door liner 220 may be provided with a rib for installing door shelves to increase the storage capacity of the refrigerator.

[0094] The door body 200 may also include an outer frame 230, which is located at the edge between the door panel 210 and the inner liner 220. The outer frame 230, the door panel 210, and the inner liner 220 enclose a door cavity, in which electrical components can be installed to increase the refrigerator's functionality. The door cavity is also provided with a thermal insulation structure, such as an insulation layer, to improve the thermal insulation performance of the door body 200.

[0095] Continue to refer to Figure 2 and Figure 3 The door outer frame 230 includes a lower end cover 240, which is disposed at the bottom of the door panel 210 and the door inner liner 220. A handle portion 202 and a hinge groove 201 are formed on the lower end cover 240.

[0096] The outer frame 230 also includes an upper cover 232, which is disposed on the top of the door panel 210 and the inner liner 220, and is opposite to the lower cover 240 along the height direction of the door body 200.

[0097] The outer door frame 230 also includes a side door frame 231, which is disposed on the side of the door panel 210 and the inner door liner 220. The top end of the side door frame 231 is connected to the upper end cover 232, and the bottom end of the side door frame 231 is connected to the lower end cover 240. There are two side door frames 231, which are respectively disposed on both sides of the width direction of the door panel 210, with one side door frame 231 being closer to the hinge side of the door body 200.

[0098] Reference Figure 4 In some embodiments of this application, the lower end cover 240 includes a bottom side portion 241 and side portions 242 disposed at both ends of the bottom side portion 241. Limit buckles 2421 are respectively provided on the two side portions 242, and a bayonet 2311 is provided on the side door frame 231. The limit buckles 2421 are engaged with the bayonet 2311 to achieve a fixed connection between the lower end cover 240 and the side door frame 231.

[0099] In some embodiments, the height of the side portion 242 of the lower end cover 240 facing away from the hinge side is greater than the height of the other side portion 242, where the height refers to the dimension of the side portion 242 along the height direction of the door body 200. This arrangement allows for the provision of a mounting opening in the side portion 242 with greater height, which is used to mount the surface light source 310 described later, facilitating maintenance and replacement.

[0100] The outer frame 230 also includes a cover plate 233, which is detachably connected to the lower cover 240. The cover plate 233 is configured to conceal the installation opening. For example, the cover plate 233 is snapped into the side portion 242 of the lower cover plate 233, which is a simple connection method and convenient for disassembly and assembly.

[0101] Continue to refer to Figure 3 A light source is installed on the inner side of the door panel 210 so that a portion of the door panel 210 can emit light, which can both provide illumination and display the working status, thereby improving the user experience. A pre-embedded box 320 is installed between the light source and the inner door liner 220 to separate the insulation structure of the door body 200 from the light source.

[0102] In this embodiment of the application, the refrigerator may include a light source assembly 300, which is disposed between the door panel 210 and the door liner 220, and the light source assembly 300 is opposite to the light-transmitting area 211 of the door panel 210.

[0103] The light source assembly 300 includes a surface light source 310 and a pre-embedded box 320. The surface light source 310 is positioned to conform to the light-transmitting area 211 of the door panel 210. The surface light source 310 facilitates the formation of a larger and more uniform light-emitting area.

[0104] The embedded box 320 is connected to the outer frame of the door 230, separating the surface light source 310 and the insulation structure inside the door 200 so that the insulation structure does not affect the surface light source 310.

[0105] In some embodiments of this application, the bottom end of the embedded box 320 and the lower end cover 240 are in inclined contact and abut against each other, which can form a sealing surface structure and also limit the embedded box 320 by using the lower end cover 240.

[0106] Furthermore, the embedded box 320 contacts and abuts against the side door frame 231, which can form a sealing surface structure on the side of the embedded box 320 and facilitate the side door frame 231 to limit the lower end cover 240.

[0107] The top of the embedded box 320 is snapped into the side door frame 231 and the lower end cover 240 respectively, realizing the connection between the embedded box 320 and the outer door frame 230. The connection method is simple.

[0108] In some possible implementations, the bottom end of the embedded box 320 contacts and abuts against the lower end cover 240 at an angle, restricting the embedded box 320 along the height direction and the thickness direction of the door body 200 (corresponding to...). Figure 6 The embedded box 320 has a Y-axis (direction of freedom) and abuts against the side door frame 231, which restricts the degree of freedom of the embedded box 320 along the width direction of the door body 200 and also restricts the degree of freedom of the embedded box 320 along the thickness direction of the door body 200. By using the snap-fit ​​connection between the embedded box 320 and the side door frame 231, the embedded box 320 is connected to the outer door frame 230 while simultaneously restricting the degree of freedom of the embedded box 320 along the height direction of the door body 200. Thus, while achieving a seal through surface contact, the degree of freedom of the embedded box 320 is restricted. The snap-fit ​​connection between the embedded box 320 and the side door frame 231 fixes the position of the embedded box 320. The connection structure is simple, easy to assemble, and helps improve assembly efficiency.

[0109] Therefore, in this embodiment of the refrigerator, a light source assembly 300 is provided inside the door 200, allowing the light-transmitting area 211 of the door panel 210 to emit light. The light source assembly 300 separates the surface light source 310 and the insulation structure inside the door 200 by providing a pre-embedded box 320. The pre-embedded box 320 makes inclined contact and abuts against the lower end cover 240 of the outer door frame 230, and makes surface contact and abuts against the side door frame 231. The surface contact achieves a sealed setting of the pre-embedded box 320, reducing the possibility of the insulation structure seeping into the surface light source 310. The position of the pre-embedded box 320 is fixed by the snap-fit ​​between the pre-embedded box 320, the connection method is simple and reliable, and it is beneficial to improve assembly efficiency. Moreover, the inclined contact between the bottom end of the pre-embedded box 320 and the lower end cover 240 provides a large contact area, which is beneficial to improve the reliability of the seal.

[0110] After the embedded box 320 is installed on the outer frame 230 of the door and the door panel 210 and the inner liner 220 are fixed, foaming can be carried out to form a thermal insulation structure without the need for additional sealing operations on the embedded box 320.

[0111] In some embodiments of this application, the pre-embedded box 320 is inserted into the outer frame 230 from top to bottom and is snapped into the outer frame 230; the two sides of the pre-embedded box 320 along the width direction of the door body 200 contact and limit the outer frame 230; the bottom end of the pre-embedded box 320 is conformally arranged with the lower end cover 240 at the bottom of the outer frame 230 to form a beveled contact.

[0112] In this embodiment, the embedded box 320 contacts the outer frame 230 on both sides along the width direction of the door body 200, thus sealing the embedded box 320 on both sides along the width direction of the door body 200. Furthermore, the bottom end of the embedded box 320 is conformally set to the lower end cover 240 at the bottom end of the outer frame 230, which not only ensures a seal between the bottom end of the embedded box 320 and the lower end cover 240, but also limits the bottom end of the embedded box 320. It also ensures that the seal at the bottom end of the embedded box 320 is not restricted by the hinge groove 201 and the handle portion 202 on the lower end cover 240, providing the possibility of setting a larger width for the embedded box 320, and thus providing the possibility of setting a wider surface light source 310. The pre-embedded box 320 is inserted into the outer frame 230 from top to bottom and snaps into the outer frame 230. The assembly method is simple, easy to disassemble and assemble, and has high assembly efficiency. Furthermore, the top-to-bottom installation method does not affect the surface contact of the pre-embedded box 320 along the width direction of the door body 200, nor does it affect the inclined surface contact between the bottom end of the pre-embedded box 320 and the lower end cover 240.

[0113] For example, a pattern is silkscreened on the light-transmitting area 211 of the door panel 210 to form a luminescent pattern, improving the appearance of the refrigerator. With the above arrangement, the light-transmitting area 211 can be the same width as the door panel 210, further improving the appearance quality of the refrigerator.

[0114] Reference Figure 5 and Figure 6 In some embodiments of this application, the lower end cover 240 is configured to form a limiting structure 243, the limiting structure 243 is configured to form a limiting surface, the limiting surface abuts against the bottom end of the embedded box 320 to restrict the degree of freedom of the embedded box 320 downward along the height direction of the door body 200.

[0115] The bottom portion 241 of the lower end cover 240 includes a bottom wall portion 2411 and a side wall portion 2412, with the side wall portion 2412 located above the front side of the bottom wall portion 2411. The bottom wall portion 2411 is recessed upward to form a groove-shaped handle portion 202. The handle portion 202 includes an outer groove wall 2021 and an inner groove wall 2022, with the inner groove wall 2022 closer to the storage compartment of the housing 100 relative to the outer groove wall 2021. There is a gap between the outer groove wall 2021 and the inner groove wall 2022 to form the handle portion 202.

[0116] The handle 202 also includes a top groove wall located at the top of the outer groove wall 2021 and the inner groove wall 2022, forming a light-transmitting opening; and a light-transmitting element 2023 is installed on the top groove wall to block the light-transmitting opening. The light emitted by the surface light source 310 can be projected downwards through the light-transmitting element 2023 to provide illumination for the drawer 110 below the door 200 to be pulled out.

[0117] In some embodiments, in order to reflect the light from the surface light source 310 to the light-transmitting element 2023, the inclined surface of the embedded box 320 facing the surface light source 310 is polished to form a polished surface for reflecting light to the light-transmitting element 2023. Alternatively, a reflector is provided on the inclined surface to reflect the light from the surface light source 310 to the light-transmitting element 2023.

[0118] At this time, the surface light source 310 can be a bidirectional surface light source. The bidirectional surface light source has a first emitting surface and a second emitting surface that are opposite to each other. The first emitting surface is opposite to the light-transmitting area 211 of the door panel 210, and the second emitting surface is opposite to the inclined surface of the embedded box 320, so as to provide light for the light-transmitting component 2023.

[0119] A gap exists between the side wall portion 2412 of the lower end cover 240 and the outer groove wall 2021, and a limiting structure 243 is disposed within this gap. Exemplarily, the limiting structure 243 includes multiple ribs, with the side of each rib facing the outer groove wall 2021 forming a limiting surface. The multiple ribs are spaced apart along the length direction of the side wall portion 2412 (corresponding to the width direction of the door body 200), which not only improves the structural strength of the lower end cover 240 but also allows for pre-embedding at the bottom end of the box 320 for limiting.

[0120] In this embodiment, a limiting structure 243 is formed by constructing a limiting surface on the lower end cover 240 to abut and limit the bottom end of the embedded box 320. The abutment structure is reliable and does not require other fixing structures, which helps to improve assembly efficiency.

[0121] Continue to refer to Figure 6 In some implementations of this application, the lower end cover 240 forms a first inclined surface, which contacts the surface of the embedded box 320. The outer groove wall 2021 is constructed to form the first inclined surface. Along the height direction of the door body 200 from bottom to top, the first inclined surface slopes inward from the outer side of the door body 200. The contact between the first inclined surface and the embedded box 320 increases the contact area, thereby improving the reliability of the seal.

[0122] In some embodiments, the outer groove wall 2021 is further configured to form a vertical surface and an arcuate surface, with the arcuate surface connecting the vertical surface and the first inclined surface. The bottom end of the embedded box 320 and the lower end cover 240 are conformally arranged so that the bottom end of the embedded box 320 simultaneously contacts the vertical surface and the arcuate surface, thereby forming a tortuous contact structure between the bottom end of the embedded box 320 and the lower end cover 240, which helps to improve the reliability of the seal.

[0123] The angle between the limiting surface of the limiting structure 243 and the first inclined surface is an acute angle, so that the limiting surface of the limiting structure 243 and the first inclined surface form a V-shaped structure, which can restrict the downward position of the bottom of the embedded box 320 and also restrict the degree of freedom of the embedded box 320 along the thickness direction of the door body 200.

[0124] Continue to refer to Figure 6 In some embodiments, a protruding limiting rib 321 is formed at the bottom end of the pre-embedded box 320. The limiting rib 321 can improve the structural strength of the pre-embedded box 320. The limiting rib 321 contacts the limiting surface, increasing the contact area between the pre-embedded box 320 and the limiting surface, and improving the reliability of the limiting structure 243 in abutting and limiting the pre-embedded box 320.

[0125] Reference Figure 7 and Figure 8 In some embodiments of this application, the embedded box 320 forms a first contact surface and a second contact surface near the hinge side of the door body 200. The first contact surface and the second contact surface intersect and have an included angle. Exemplarily, the first contact surface is parallel to the door panel 210, and the second contact surface is perpendicular to the first contact surface.

[0126] In this design, the embedded box 320 forms a first plate portion 322 and a second plate portion 323 on the side near the hinge of the door body 200. The first plate portion 322 and the second plate portion 323 are connected. The first plate portion 322 is parallel to the door panel 210, and the second plate portion 323 is perpendicular to the door panel 210. The side of the first plate portion 322 facing the door panel 210 forms a first contact surface, and the side of the second plate portion 323 facing the side door frame 231 forms a second contact surface.

[0127] The first contact surface and the second contact surface respectively contact the side door frame 231 and restrict the degree of freedom of the embedded box 320 along the width and thickness directions of the door body 200.

[0128] Therefore, the embedded box 320, near the hinged side of the door body 200, forms an intersecting first contact surface and a second contact surface, which respectively contact the side door frame 231, thus increasing the contact area and improving sealing performance. The bent-shaped contact surface between the embedded box 320 and the side door frame 231 also increases the resistance to the flow path of the foaming material, further enhancing the sealing effect. Furthermore, the first and second contact surfaces simultaneously restrict the degrees of freedom of the embedded box 320 along both the width and thickness directions of the door body 200, improving the limiting effect on the embedded box 320.

[0129] Reference Figure 7 and Figure 9 In some embodiments of this application, the embedded box 320 forms a third plate portion 324 on the side opposite to the hinge of the door body 200. The third plate portion 324 is arranged parallel to the door panel 210 and forms a third contact surface, which is in surface contact with the side portion 242 of the lower end cover 240. This achieves a sealing structure while restricting the position of the embedded box 320 along the thickness direction of the door body 200.

[0130] The embedded box 320 also includes a fourth plate portion 325, which is located at the top of the third plate portion 324 and is disposed perpendicular to the door panel 210. The fourth plate portion 325 abuts against the side portion 242 of the lower end cover 240, which can limit the position of the embedded box 320 along the height direction of the door body 200.

[0131] Continue to refer to Figure 8 and Figure 9 The embedded box 320 has a reinforcing rib 326 on one side away from the light source 310. This not only helps to improve the structural strength of the embedded box 320, but also provides an attachment position for the foamed material to form an insulation structure, thereby improving the stability of the contact and connection between the insulation structure and the embedded box 320.

[0132] A wire passage 327 is formed at the top of the pre-embedded box 320 so that the cable connected to the surface light source 310 can pass through and be electrically connected to the power supply and control devices of the refrigerator.

[0133] Continue to refer to Figure 7 In some embodiments of this application, an elastic buckle 328 is provided on the side of the embedded box 320 away from the hinge. One end of the elastic buckle 328 is connected to the side of the embedded box 320 facing the door panel 210, and the other end of the elastic buckle 328 extends toward the cover plate 233. There is a gap between the elastic buckle 328 and the embedded box 320, so that the elastic buckle 328 has elastic deformation space. The side of the elastic buckle 328 facing the door panel 210 is configured to abut against the surface light source 310, thereby pressing the surface light source 310 tightly against the door panel 210.

[0134] like Figure 7 As shown, when disassembling and installing the surface light source 310, the operator opens the cover plate 233 and presses the elastic buckle 328 along the negative direction of the Y-axis, causing the elastic buckle 328 to deform and increase the gap between the elastic buckle 328 and the door panel 210, so that the surface light source 310 can be smoothly disassembled and installed from the installation port; then the elastic buckle 328 is released so that the elastic buckle 328 can abut against the surface light source 310, which helps to improve the tightness of the fit between the surface light source 310 and the door panel 210, and reduces the possibility of the surface light source 310 colliding with the door panel 210 during transportation or when opening and closing the door due to the gap between the surface light source 310 and the door panel 210.

[0135] Recombined Figure 8 The side door frame 231 is provided with a first latching member 2312. Exemplarily, the side door frame 231 has two slits spaced apart along the height direction of the door body 200. The portion between the two slits is recessed towards the inner door liner 220 to form the first latching member 2312. A gap exists between the first latching member 2312 and the side door frame 231, forming a latching channel extending along the height direction.

[0136] The pre-embedded box 320 is provided with a first buckle 3221 at the top of the hinge side near the door body 200. The first buckle 3221 is engaged with the first snap-fit ​​member 2312 from top to bottom. The first buckle 3221 can be provided at the top of the first plate part 322 and the second plate part 323.

[0137] The first latch 3221 is inserted into the latching channel and latches with the bottom end of the first latching member 2312 to restrict the degree of freedom of the embedded box 320 in the upward direction of height.

[0138] Recombined Figure 9 A second snap-fit ​​member 3251 is provided at the top of the pre-embedded box 320 on the hinged side opposite to the door body 200. The second snap-fit ​​member 3251 is provided on the fourth plate portion 325. The second snap-fit ​​member 3251 can be a cylindrical structure provided on the fourth plate portion 325, the cylindrical structure forming a snap-fit ​​channel, and the snap-fit ​​channel extending downward to and through the fourth plate portion 325.

[0139] A second latch 2313 is provided on the side of the lower end cover 240, and the second latch 2313 is engaged with the second latching member 3251 from top to bottom. The second latch 2313 is provided on the side portion 242 of the lower end cover 240.

[0140] When the pre-embedded box 320 is inserted from top to bottom, the second buckle 2313 is inserted into the snap-fit ​​channel of the second snap-fit ​​member 3251 and snaps with the top of the second snap-fit ​​member 3251, restricting the degree of freedom of the pre-embedded box 320 to move upward in the height direction.

[0141] Therefore, in this embodiment, the embedded box 320 is connected to the side door frame 231 by the first snap fastener 3221 and the first snap fastener 2312 along both sides of the width direction of the door body 200; and the embedded box 320 is connected to the side of the lower end cover 240 by the second snap fastener 2313 and the second snap fastener 3251, thus improving the stability of the connection of the embedded box 320. Furthermore, both the first snap fastener 3221 and the second snap fastener 2313 are engaged from top to bottom to achieve connection and positioning, without affecting the abutment and surface contact between the bottom end of the embedded box 320 and the lower end cover 240.

[0142] Continue to refer to Figure 10 and Figure 11 In some embodiments of this application, a first adhesive application surface 3291 is formed at the top of the embedded box 320. The first adhesive application surface 3291 is parallel to the door panel 210 and extends along the width direction of the door body 200. The first adhesive application surface 3291 is used to apply adhesive to bond the door panel 210 and simultaneously seal the top of the embedded box 320.

[0143] The lower end cover 240 and the side door frame 231 form a second adhesive surface 250, which is flush with the first adhesive surface 3291; the door panel 210 is bonded to the first adhesive surface 3291 and the second adhesive surface 250 respectively.

[0144] By setting the first adhesive application surface 3291 and the second adhesive application surface 250 to be flush, adhesive can be applied to the first adhesive application surface 3291 and the second adhesive application surface 250 in sequence without adjusting the adhesive application parameters. The adhesive application operation is simple, which helps to improve assembly efficiency.

[0145] In some embodiments, the upper cover 232 forms a third adhesive surface 2321 on the side facing the door panel 210. The third adhesive surface 2321 is flush with the second adhesive surface 250, forming an annular adhesive area that is bonded to the periphery of the door panel 210.

[0146] Continue to refer to Figure 11The top of the pre-embedded box 320 has an adhesive plate portion 329, and the adhesive plate portion 329 forms a first adhesive surface 3291 on the side facing the door panel 210. The adhesive plate portion 329 forms a protruding rib 3292, which is located at the bottom end of the first adhesive surface 3291.

[0147] By forming a protruding rib 3292 at the bottom end of the first adhesive surface 3291, a barrier is provided for the adhesive, preventing excess adhesive from entering the mounting area of ​​the surface light source 310.

[0148] In some embodiments, the adhesive plate portion 329 forms an adhesive receiving groove 3293, which is disposed near the top side of the rib 3292 to provide adhesive receiving space, further reducing the installation area of ​​the adhesive entering the surface light source 310.

[0149] Reference Figure 12 In some embodiments of this application, the second adhesive application surface 250 includes a first adhesive application area 251 and a second adhesive application area 252. The edge of the side door frame 231 forms the first adhesive application area 251, and the lower end cover 240 forms the second adhesive application area 252. The adhesive application width of the second adhesive application area 252 is smaller than the adhesive application width of the first adhesive application area 251.

[0150] The bottom portion 241 of the lower end cap 240 and the side portion 242 facing away from the hinge side both form a second adhesive application area 252. The second adhesive application area 252 of the side portion 242 may be provided with a recess to accommodate excess adhesive.

[0151] The adhesive application width is the dimension along the width direction of the adhesive application area, which is perpendicular to the length direction of the adhesive application area. Taking the second adhesive application area 252 of the bottom side portion 241 of the lower end cap 240 as an example, this second adhesive application area 252 extends along the X-axis direction, and its adhesive application width is the dimension along the Z-axis direction. Taking the second adhesive application area 252 of the side portion 242 of the lower end cap 240 as an example, this second adhesive application area 252 extends along the Z-axis direction, and its adhesive application width is the dimension along the X-axis direction.

[0152] The two ends of the first adhesive application surface 3291 are respectively opposite to the first adhesive application area 251, which is beneficial to use the two ends of the first adhesive application surface 3291 as the start and end of adhesive application.

[0153] The width of the first adhesive application surface 3291 is greater than the width of the second adhesive application area 252, which helps to increase the bonding area between the embedded box 320 and the door panel 210, thereby improving the sealing performance of the top of the embedded box 320 and also improving the reliability of fixing the middle area of ​​the door panel 210.

[0154] Because the glue application width of the second glue application area 252 is relatively small, it is not used as the starting point for glue application. This is because the amount of glue at the starting point is larger and more likely to overflow.

[0155] In this embodiment, the annular glue application area formed by the door outer frame 230 and the first glue application surface 3291 are glued, and the glue application paths do not overlap. One end of the first glue application surface 3291 along its length is used as the glue application starting point.

[0156] In some embodiments of this application, combined with Figure 13 The refrigerator has two side-by-side doors 200, with their hinged sides close to each other. The starting point for applying the sealant is the end of the first sealant-applying surface 3291 of the left door 200 facing away from the hinged side. The red dashed line with arrows in the diagram represents the sealant application path. The starting point for applying the sealant is point A, and the ending point is point B.

[0157] Although the end point of the glue application is located in the second glue application area 252, it is located at the end of the second glue application area 252 near the first glue application area 251, so the possibility of glue overflow is low.

[0158] By using the end of the first adhesive application surface 3291 facing away from the hinge side as the adhesive application starting point, the adhesive application equipment can move to the right side door 200 in a shorter distance.

[0159] Therefore, in the refrigerator of this embodiment, the pre-embedded box 320 is sealed and abutted against the inclined surface of the lower end cover 240, the pre-embedded box 320 is in surface contact with and limited by the side door frame 231, and the pre-embedded box 320 is snapped into the side door frame 231, thereby realizing the connection and limitation between the pre-embedded box 320 and the outer door frame 230. After applying glue according to the glue application path, the insulation structure can be foamed without additional sealing, simplifying the process and improving the assembly efficiency of the refrigerator door 200.

[0160] Furthermore, by providing an installation port and a cover plate 233 on the side of the door body 200, the surface light source 310 can be disassembled and installed from the side, making maintenance and disassembly simple and convenient.

[0161] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
