[0036] Example 1

[0037] See also Figure 1-8 As shown, this embodiment discloses a self-sealing embedded box. The self-sealing embedded box of this embodiment is applied to a refrigerator and includes:

[0038] The box body 1 has an opening on one side. The box body 1 is provided with an insertion port 11 for providing a space for inserting electronic components.

[0039] The box cover 2 is arranged on the opening side of the box body 1; the box cover 2 is provided with a first rib 21 and a second rib 22, and the edge of the opening side of the box body 1 is clamped between the first rib 21 and the second rib 22.

[0040] The self-sealing embedded box of this embodiment is clamped to the side edge of the opening of the box body 1 by the first rib 21 and the second rib 22, thereby realizing a sealed connection between the box cover 2 and the box body 1, so that the embedded box has a self-sealing effect, significantly reducing the consumption of sealing tape, and effectively avoiding the risk of foaming liquid penetrating into the embedded box, protecting the safety of electronic components, and extending the service life of the refrigerator; by covering the box body 1 with the box cover 2, a rapid sealing operation of the embedded box is achieved, thereby improving the production and processing efficiency of the refrigerator and helping to enhance the market competitiveness of the refrigerator.

[0041] During specific implementation, first select the installation position on the refrigerator, and then firmly connect the box body 1 to the refrigerator; place the electronic components in the box body 1, or introduce the leads of the electronic components from the outside of the box body 1 into the box body 1, and after the electronic components are plugged in at the plug interface 11, seal and snap the box cover 2 to the box body 1; after completing the sealing process of the embedded box, carry out the foaming process of the refrigerator, fill the refrigerator with foaming liquid, and wrap the outer wall of the embedded box, and wait for the foaming liquid to solidify to form an insulation layer to further stabilize the embedded box on the refrigerator.

[0042] Specifically, a protective cavity 12 is provided within the box body 1, surrounding the plug port 11. The bottom of the protective cavity 12 is connected to the bottom wall of the box body 1, and the top of the protective cavity 12 is flush with the edge of the opening of the box body 1. When the box lid 2 is closed over the box body 1, the top of the protective cavity 12 abuts the lid 2, forming a closed structure for the protective cavity 12. The protective cavity 12 and the box body 1 form a double protection structure, preventing the foaming liquid from slightly seeping into the box body 1 through the first ribs 21 and the second ribs 22 and contaminating and sticking to electronic components, leads, or terminals. This further improves the sealing performance of the embedded box and ensures the safety of the electronic components and the wiring of the refrigerator.

[0043] Specifically, the protective cavity 12 includes at least three protective walls 121, which are distributed around the periphery of the plug port 11 and interconnected. The bottoms of the protective walls 121 are connected to the bottom wall of the box body 1, and the tops of the protective walls 121 are flush with the edges of the openings of the box body 1. The protective cavity 12 is surrounded by the protective walls 121, leaving the bottom of the protective cavity 12 open, facilitating communication between the interior of the protective cavity 12 and the plug port 11. The top of the protective cavity 12 is also open, facilitating observation of the connection status of the electronic components. Furthermore, the protective cavity 12 is hollow, accommodating the leads and / or components of the electronic components.

[0044] Specifically, a gap exists between the protective cavity 12 and the sidewall of the box body 1, forming a foaming liquid flow channel 13. The foaming liquid flow channel 13 is used to guide the foaming liquid that slightly penetrates into the box body 1 to diffuse, thereby preventing the foaming liquid from locally accumulating and seeping into the protective cavity 12 through the gap between the top of the protective cavity 12 and the box cover 2.

[0045] Specifically, the bottom wall of the box body 1 is penetrated by a screw hole 14, which is located in the foaming liquid flow channel 13. The screw hole 14 facilitates the secure connection between the embedded box and the refrigerator by screws. It is understood that in other embodiments, the box body 1 can be adhered to the refrigerator by glue or tape, or the box body 1 can be clamped to the refrigerator by a clamping structure instead of screw connection. The foaming liquid flow channel 13 is connected to the screw hole 14 to facilitate the drainage of the foaming liquid. Figure 7 As shown, the foaming liquid flows along the foaming liquid flow channel 13 to the screw hole 14, avoiding the accumulation of foaming liquid, ensuring that the inside of the protective cavity 12 remains dry, and ensuring the safety of electronic components.

[0046] Specifically, the box body 1 is provided with a wire feed slot 15, and the protective cavity 12 is provided with a wire pass slot 122. The provision of the wire feed slot 15 and the wire pass slot 122 facilitates the placement of electronic components outside the embedded box, allowing the leads of the electronic components to pass through the wire feed slot 15, the foaming liquid flow channel 13, and the wire pass slot 122 in sequence into the protective cavity 12, thereby facilitating subsequent plug-in operations.

[0047] In this embodiment, a 5 mm gap exists between the protective cavity 12 and the sidewall of the box body 1. The 5 mm width of the foaming liquid flow channel 13 facilitates the movement of one end of the lead wire within the foaming liquid flow channel 13 after entering the foaming liquid flow channel 13 through the wire inlet groove 15, thereby smoothly moving to the wire passing groove 122 and entering the protective cavity 12. It will be appreciated that in other embodiments, the width of the gap between the protective cavity 12 and the sidewall of the box body 1 can be adjusted according to actual needs.

[0048] Specifically, the wire-passing groove 122 is staggered with the wire-inlet groove 15. The foaming liquid that slightly seeps into the foaming liquid flow channel 13 from the wire-inlet groove 15 is likely to accumulate near the wire-inlet groove 15. The wire-inlet groove 15 and the wire-passing groove 122 are arranged opposite each other, which increases the risk of foaming liquid accumulating in the wire-passing groove 122. The staggered arrangement of the wire-passing groove 122 and the wire-inlet groove 15 helps the wire-passing groove 122 avoid the peak point of foaming liquid accumulation, prevents the foaming liquid from entering the protective cavity 12, and prevents contamination of the electronic component connection points and damage to the electronic components.

[0049] Preferably, the wire feed groove 15 is formed by a recessed edge of the opening side of the box body 1, and the wire passing groove 122 is formed by a recessed edge of the top edge of the protective cavity 12. The wire feed groove 15 and the wire passing groove 122 are respectively located at the end of the box body 1 and the protective cavity 12 away from the bottom wall of the box body 1, so that the lead wires occupy the upper space of the foaming liquid flow channel 13, so that the foaming liquid cannot overflow into the upper space of the foaming liquid flow channel 13; at the same time, the vertical accommodation space of the foaming liquid is increased in the embedded box, making it difficult for the foaming liquid that slightly penetrates into the lower space of the foaming liquid flow channel 13 to contact the wire passing groove 122, greatly reducing the risk of the foaming liquid entering the protective cavity 12.

[0050] Specifically, a wire block 17 is provided within the housing 1, with its ends connected to the protective cavity 12 and the sidewall of the housing 1, respectively. The wire block 17 is tilted from the wire entry slot 15 toward the wire passage slot 122. The wire block 17 is used to guide the wires from the wire entry slot 15 into the housing 1 and along the protective wall 121 to the wire passage slot 122, thereby improving the convenience and flexibility of wire movement and contributing to increased efficiency and accuracy in connecting electronic components.

[0051] In this embodiment, there are multiple plug-in ports 11. All leads are sequentially routed through the wire entry slot 15 and the wire pass-through slot 122 before being routed to the corresponding plug-in ports 11 for connection. The plug-in ports 11 of this embodiment can be used to connect to the wiring terminals of the refrigerator's internal electrical wiring, allowing the leads of electronic components to connect to the wiring terminals of the refrigerator's internal electrical wiring, thereby achieving electrical connection between the electronic components and the refrigerator's power supply and control device.

[0052] In this embodiment, the plurality of plug ports 11 are used to connect to the corresponding wiring terminals of the defrost sensor and various temperature sensors, respectively, so that the embedded box can protect the connection security of the defrost sensor and the temperature sensor. It is understood that in other embodiments, the plug ports 11 can accommodate the corresponding wiring terminals of the main control board, lighting, display, or other electronic components as needed.

[0053] Specifically, a stopper 123 is provided in the protective cavity 12. The stopper 123 extends from one end of the wire-passing slot 122 close to the wire-inlet slot 15 into the protective cavity 12. A stopper wall 1231 is provided on the stopper 123 in a direction away from the wire-inlet slot 15. The width of the stopper wall 1231 is smaller than the width of the wire-passing slot 122. Figure 8 As shown, after all the leads enter the wire through slot 122, they continue to move along the block 123 and are pressed against the blocking wall 1231, and are arranged in sequence from top to bottom at the blocking wall 1231 in the order of plugging to avoid the leads from crossing, thereby ensuring the neatness of the lead distribution inside the protective cavity 12, reducing the plugging error rate, ensuring the accuracy of the electronic component plugging, and thus reducing the risk of damaging the foaming structure to remove the embedded box and reconnect the electronic components, thereby ensuring the structural stability and durability of the embedded box and the refrigerator.

[0054] Specifically, the self-sealing embedded box further includes a connecting piece 3; the two ends of the connecting piece 3 are respectively connected to the box body 1 and the box cover 2, and the box cover 2 is rotatably connected to the box body 1 via the connecting piece 3. The box cover 2 and the box body 1 are connected via the connecting piece 3, so that the box cover 2 and the box body 1 are matched. During the assembly of the embedded box, there is no need to find or select the box body 1 and the box cover 2 of corresponding specifications, which saves assembly time and improves the installation and sealing efficiency of the embedded box. The box cover 2 can be flipped relative to the box body 1 to facilitate the opening and closing of the box cover 2. When it is necessary to install or maintain electronic components, the box cover 2 can be easily opened, thereby allowing for simple and quick removal or replacement of electronic components without excessive damage to the insulation layer.

[0055] Specifically, the connecting piece 3 is provided with two separation ribs 31, which are arranged sequentially from the end of the connecting piece 3 closest to the lid 2 to the end further away from the lid 2. A folding groove 32 is formed between the two separation ribs 31. The arrangement of the two separation ribs 31 enables the connecting piece 3 to bend along the folding groove 32, causing the lid 2 to rotate about the folding groove 32, thereby changing the separation angle between the lid 2 and the box body 1. When the two separation ribs 31 approach each other, the lid 2 and the box body 1 are brought closer together; when the two separation ribs 31 overlap, the lid 2 and the box body 1 are sealed together; when the two separation ribs 31 move away from each other, the lid 2 and the box body 1 move away from each other.

[0056] Specifically, first ribs 21 are provided along the side of the lid 2 away from the connecting piece 3 and along the edges of the two adjacent sides away from the side away from the connecting piece 3. Second ribs 22 are provided around the periphery of the protective cavity 12, and notches 221 are provided in the second ribs 22 corresponding to the wire blocks 17. The connecting piece 3 is located between the lid 2 and the box body 1, and the side of the lid 2 near the connecting piece 3 does not require the first rib 21, thereby preventing the first rib 21 from obstructing or interfering with the rotation of the lid 2. The notches 221 in the second ribs 22 are provided to accommodate the wire blocks 17, preventing the second ribs 22 and the wire blocks 17 from squeezing each other, thereby increasing the gap between the lid 2 and the box body 1 and affecting the sealing of the embedded box.

[0057] Specifically, the distance between the first rib 21 and the second rib 22 corresponds to the thickness of the side edge of the opening of the box body 1. In this embodiment, the distance between the first rib 21 and the second rib 22 is 2.5 mm. This 2.5 mm thickness prevents the thicker box body 1 from affecting the flexibility of the snap-fit between the lid 2 and the box body 1, while also ensuring the structural stability of the embedded box structure. In other embodiments, the distance between the first rib 21 and the second rib 22 can be adjusted according to actual needs.

[0058] Specifically, the box body 1, the connecting piece 3 and the box cover 2 are integrated into a structure that simplifies the production process, reduces the assembly steps between the box body 1, the connecting piece 3 and the box cover 2, and thus reduces the production cost of the embedded box.

[0059] Preferably, the box body 1, the connecting piece 3, and the box cover 2 are injection molded using PP material. PP (polypropylene) material has good flexibility and plasticity. When the edge of the opening of the box body 1 is inserted between the first rib 21 and the second rib 22, the first rib 21 and the second rib 22 are slightly deformed under pressure to wrap the edge of the opening of the box body 1 from both sides, thereby achieving a tighter connection between the box cover 2 and the box body 1 and ensuring the durability of the sealing effect between the box cover 2 and the box body 1. PP material is low in cost. The self-sealing structure formed by the box cover 2 and the box body 1 replaces sealing tape and sponge, greatly reducing the cost of sealing materials and thereby improving the economic benefits of the embedded box. PP material is also highly corrosion-resistant and suitable for embedding in the insulation layer, thereby improving the durability of the embedded box and the safety of electronic components.

[0060] Specifically, the first ribs 21, the second ribs 22, the top of the protective wall 121, and the side edges of the opening of the box body 1 are all chamfered. The chamfered arrangement of the first ribs 21, the second ribs 22, the top of the protective wall 121, and the side edges of the opening of the box body 1 facilitates rapid engagement and separation between the side edges of the opening of the box body 1 and the first ribs 21 and the second ribs 22, while preventing rigid collisions between the box cover 2, the box body 1, and the protective cavity 12, thereby ensuring the durability of the embedded box.

[0061] Specifically, the edges of the wire inlet slot 15, wire through slot 122, block 123, and retaining wall 1231 are all chamfered. These chamfers prevent the wires from breaking due to excessive bending or pulling, thus ensuring the safety and reliability of the refrigerator's circuit system.

[0062] Specifically, the box cover 2 is provided with a buckle 23, and the box body 1 is provided with a slot 16 corresponding to the buckle 23; the buckle 23 is engaged with the slot 16, thereby securely connecting the box cover 2 to the box body 1. The buckle 23 engages with the slot 16, thereby firmly connecting the box cover 2 to the box body 1, preventing the box cover 2 from separating from the box body 1 when the box cover 2 and the box body 1 are sealed together, and ensuring the reliability of the sealing effect between the box cover 2 and the box body 1.

[0063] Specifically, a snap-fit block 24 is provided on the side of the cover 2 away from the connecting piece 3. The snap-fit block 24 is used to abut the side wall of the box body 1. The snap-fit block 24 and the buckle 23 abut the box body 1 from both sides, thereby enhancing the locking force between the cover 2 and the box body 1, improving the stability of the connection between the cover 2 and the box body 1, and further improving the sealing effect of the embedded box.

[0064] Specifically, the lid 2 is provided with reinforcing ribs 25. In this embodiment, there are four reinforcing ribs 25, which are distributed in a "well" shape on the lid 2 and are arranged corresponding to the middle portion of the protective cavity 12. The reinforcing ribs 25 increase the structural strength of the lid 2 and enhance its ability to resist deformation. During the production, processing, and use of the refrigerator, when the embedded box is affected by external forces or the environment, such as vibration, temperature changes, and humidity changes, the reinforcing ribs 25 can prevent the lid 2 from deforming significantly and compressing the leads or expanding and increasing the gap between the lid 2 and the box body 1, thereby extending the service life of the embedded box and ensuring the sealing effect of the embedded box.

[0065] Specifically, the inner wall of the protective cavity 12 is provided with a plurality of reinforcing ribs 124, the bottoms of which are connected to the bottom wall of the box body 1. The reinforcing ribs 124 provide stable support for the protective wall 121, helping to improve the overall structural strength of the protective cavity 12. They also disperse the pressure on the protective wall 121, improving the protective cavity 12's ability to resist external pressure and deformation. This prevents the protective wall 121 from bending under pressure when the box cover 2 presses against the protective cavity 12, prevents the gap between the top of the protective cavity 12 and the box cover 2 from increasing, ensures the sealing of the protective cavity 12, and further protects the safety of the electronic components.

[0066] Example 2

[0067] See also Figure 1-8 As shown, this embodiment discloses a refrigerator, which includes the self-sealing embedded box of the first embodiment.

[0068] The embedded box quickly and conveniently seals the box body 1 with the lid 2, improving the box's sealing efficiency. The first and second ribs 21 and 22 on the lid 2 tightly engage the edges of the box body 1's opening, forming a self-sealing structure. This significantly reduces the use of sealing tape and sponge, thereby reducing costs and improving the box's economic benefits. The inherent sealing properties of the embedded box prevent foaming fluid from wetting the wiring of electronic components, ensuring the reliability of the refrigerator's circuit system. The self-sealing embedded box significantly improves refrigerator production efficiency, cost control, and product quality, significantly enhancing the refrigerator's market competitiveness.

[0069] This embodiment provides a self-sealing embedded box and a refrigerator, wherein the first rib and the second rib are clamped to the side edge of the box body opening, thereby achieving a sealed connection between the box cover and the box body, significantly reducing the consumption of sealing tape, effectively avoiding the risk of foaming liquid penetrating into the embedded box, protecting the safety of electronic components, and extending the service life of the refrigerator; by covering the box body with the box cover, a rapid sealing operation of the embedded box is achieved, thereby improving the production and processing efficiency of the refrigerator and helping to enhance the market competitiveness of the refrigerator.
