[0002] Various household appliances are prone to bumps during transportation due to falling and shaking during handling or transportation, which can cause the appliances to break. Currently, household appliances have corresponding packaging structure protection, including corrugated paper packaging boxes, foams, packaging bags, etc.

[0003] To ensure that the appliances can run smoothly and completely during installation and use, a parts bag is usually attached to the packaging box when the household appliance is packaged and shipped. The parts bag contains various small parts, accessories, and attachments related to the corresponding appliance. Household appliances that require a parts bag usually include large appliances such as refrigerators, washing machines, dishwashers, etc.; or small appliances such as electric rice cookers, microwaves, etc.

[0004] The prior art CN202320547624.X discloses a packaging structure, which includes an upper side plate and a lower side plate installed on the upper and lower sides of a household appliance. The upper side plate is provided with a containing cavity for containing the household appliance. The upper side of the upper side plate is recessed downward to form a cavity for installing an accessory box. The upper side plate and the lower side plate are provided with upper and lower vertical columns that abut against each other after installation. By recessing the upper side of the upper side plate downward to form a cavity for containing and installing the accessory box, a plurality of support bar mounting positions are opened on the upper side of the upper side plate. Each support bar mounting position is provided with a support bar that spans the cavity.

[0005] In the prior art, after the accessory box is installed in the cavity, the support bar in the mounting position blocks the accessory box on the upper side of the upper side plate to prevent the accessory box from detaching from the cavity. However, since the support bar only protects the accessory box from above, the stability of the accessory box is low, and the accessory box may shake and become unstable in the cavity during transportation or handling. Moreover, when the packaged household appliance shakes significantly, the accessory box may detach from the cavity on the upper side SUMMARY

[0006] The utility model aims to provide a packaging structure that solves the problem of instability and detachment of the accessory box from the cavity, reduces the possibility of shaking of the accessory box after packaging, and improves the stability of the packaged accessory box.

The upper side of the top plate is not provided with an opening, even if the accessory bag shakes, it will not come out of the top plate, reducing the possibility of shaking of the accessory bag from the cavity during transportation, further improving the stability of the accessory bag, and avoiding the collision between the accessory bag and the peripheral wall of the household appliance when the accessory bag slides out of the cavity.

[0009] Further, the lower surface of the top plate is provided with a protruding portion protruding downward, and the protruding portion is close to the top of the household appliance to limit the accessory bag around the peripheral wall of the accessory bag.

[0010] By setting the protruding portion close to the top of the household appliance, the protruding portion limits the accessory bag around the peripheral wall of the accessory bag, reducing the possibility of the accessory bag coming out of the cavity from the gap between the top plate and the top wall of the household appliance, and further improving the stability of the accessory bag between the top plate and the top of the household appliance.

[0011] Further, the top of the household appliance has a first plane supporting the accessory bag and a first step surrounding the peripheral wall of the accessory bag, and the protruding portion is located on the outer side of the first step.

[0012] The accessory bag is placed on the first plane on the top of the household appliance and inside the first step, and the protruding part is outside the first step, thereby reducing the gap between the bottom wall of the protruding part and the top of the household appliance and further improving the stability of the accessory bag.

[0013] Further, the inner wall of the protruding part is in gap cooperation with the outer wall of the step.

[0014] The inner wall of the protruding part is in gap cooperation with the outer wall of the step, thereby reducing the installation and dismounting difficulty of the top plate; in addition, after the gap cooperation between the inner wall of the protruding part and the outer wall of the step, an overlapping part is formed in the horizontal direction, thereby improving the stability of the accessory bag in the cavity and reducing the possibility of the accessory bag sliding out of the cavity.

[0015] Further, the outer wall of the protruding part is provided with a reinforcing rib, and the reinforcing rib is connected with the top plate to stabilize the protruding part.

[0016] The outer wall of the protruding part is provided with a reinforcing rib, and the reinforcing rib is connected with the top plate to improve the stability of the protruding part and reduce the possibility of the accessory bag sliding out due to the fracture of the protruding part under the condition of large vibration of the box body.

[0017] Further, the inner wall of the protruding part is provided with a first rib plate, the lower surface of the first rib plate is inclined and has the same inclination angle as the top of the household appliance, and the distance between the lower surface of the first rib plate and the top of the household appliance is less than the thickness of the accessory bag.

[0018] The inner wall of the protruding part is provided with a first rib plate, the lower surface of the first rib plate is inclined and has the same inclination angle as the top of the household appliance, and the distance between the lower surface of the first rib plate and the top of the household appliance is less than the thickness of the accessory bag, thereby avoiding the possibility of the accessory bag sliding out of the top plate through the gap between the lower surface of the first rib plate and the top of the household appliance.

[0019] Further, the center part of the lower surface of the top plate is provided with a first convex rib, and the first convex rib is pressed against the middle part of the accessory bag.

[0020] The first convex rib is arranged in the middle part of the lower surface of the top plate, and when the top plate is pressed against the accessory bag, the first convex rib is pressed against the middle part of the accessory bag, thereby reducing the possibility of shaking of the accessory bag during transportation and improving the stability of the accessory bag.

[0038] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0039] like Figures 1 to 8As shown, this utility model provides a packaging structure, including a box body 1. The box body 1 is usually made of cardboard or wood, but can also be made of polymer material or metal sheet as needed. The box body 1 has a cavity 11 for accommodating a household appliance 2. A top plate 4 and a bottom plate 3 are respectively provided between the top and bottom of the household appliance 2 and the top and bottom walls of the cavity 11. The top plate 4 and the bottom plate 3 are used to stabilize the household appliance 2 within the cavity 11. When packaging the household appliance 2, the upper port of the box body 1 is opened, and the bottom plate 3 is inserted into the cavity 11 from the upper port of the box body 1, with the lower surface of the bottom plate 3 adhering to the inner bottom surface of the cavity 11. After the bottom plate 3 is placed, the household appliance 2 is placed in the cavity 11, with the bottom end of the household appliance 2 pressing against the bottom wall of the bottom plate 3. After the household appliance 2 is placed, the top plate 4 is placed on top of the household appliance 2. Figure 1 and Figure 2 As shown, the lower surface of the top plate 4 is recessed upward to form a groove 41. After the top plate 4 is placed on top of the household appliance 2, a cavity 21 is formed between the groove 41 and the top of the household appliance 2. Before placing the top plate 4, the accessory bag 5 is placed on top of the household appliance 2, and then the top plate 4 is placed on top of the household appliance 2, accommodating the accessory bag 5 in the cavity 21. The top plate 4 presses the accessory bag 5 downward against the top of the household appliance 2. The accessory bag 5 is pressed down by the top plate 4. After the accessory bag 5 is placed, the top plate 4 does not have a groove that runs through the top plate 4 in the vertical direction, which prevents the accessory bag 5 from coming off the top plate 4 from the center during transportation, thus improving the stability of the accessory bag 5 after packaging. The pressing method reduces the possibility of the accessory bag 5 coming off the cavity 21 and shaking during transportation, improving the stability of the accessory bag 5 and preventing the accessory bag 5 from sliding out of the cavity 21 and colliding with the outer wall of the household appliance 2. In another embodiment, when the upper surface of the household appliance 2 has a downwardly recessed cavity, and the top plate 4 covers the top of the household appliance 2, the cavity and the lower surface of the top plate 4 can also form a cavity 21 for accommodating the accessory bag 5; in addition, the cavity 21 can also be formed by splicing the cavity on the top of the household appliance 2 and the groove 41 on the top plate 4.

[0040] To improve the stability of accessory bag 5, such as Figure 1 and Figure 2 As shown, the lower surface of the top plate 4 has a downwardly protruding protrusion 42, which forms the outer peripheral sidewall of the groove 41. When the top plate 4 is placed on top of the household appliance 2, the protrusion 42 surrounds the outer periphery of the accessory bag 5 to limit the accessory bag 5, and the protrusion 42 is close to the top of the household appliance 2; more specifically, as Figure 1 and Figure 3As shown, the top of the household appliance 2 has a first flat surface 22 and a first step 23 surrounding the accessory bag 5. The first step 23 surrounds the first flat surface 22. When the accessory bag 5 is placed, it rests on the first flat surface 22 and is surrounded by the first step 23, ensuring that the accessory bag 5 is located inside the cavity 21 after placement. After the top plate 4 is installed, the protrusion 42 is located outside the first step 23, preventing the accessory bag 5 from detaching from the cavity 21 horizontally, further improving the stability of the accessory bag 5. The top of the household appliance 2 has a mating surface located outside the first step 23. The lower surface of the protrusion 42 is clearance-fitted with the mating surface, improving the ease of installation of the top plate 4 and ensuring the stability of the accessory bag 5 after it is contained in the cavity 21. Furthermore, the clearance-fitting method between the inner wall of the protrusion 42 and the outer wall of the first step 23 reduces the difficulty of installing the top plate 4, improves the convenience of packaging the household appliance 2, and facilitates the removal of the top plate 4 when unpacking the box 1, reducing the difficulty of disassembling and assembling the household appliance 2.

[0041] In another embodiment, such as Figure 2 As shown, the outer wall of the protrusion 42 is provided with a reinforcing rib 48, which is connected to the bottom wall of the top plate 4. The reinforcing rib 48 increases the strength of the protrusion 42, reduces the possibility of the accessory bag 5 hitting the inner wall of the protrusion 42 during transportation and causing the protrusion 42 to break, thereby improving the stability of the accessory bag 5 after it is contained in the cavity 21.

[0042] To stabilize the accessory bag 5 and facilitate the placement of the top plate 4, such as Figure 2 and Figure 3 As shown, the inner wall of the protrusion 42 is provided with a first rib 47, and a first inclined surface 231 is formed between the first step 23 and the first plane 22. After the first rib 47 is set, the inclination angle of the lower surface of the first rib 47 is kept the same as the inclination angle of the first inclined surface 231, so that the top plate 4 can be kept relatively parallel after placement, reducing the possibility that the upper surface of the top plate 4 will not be horizontal due to different inclination angles after placement. In addition, the distance between the lower surface of the first rib 47 and the first inclined surface 231 is less than the thickness of the accessory bag 5. If the packaged household appliance 2 and accessory bag 5 experience severe vibration, the design that the distance between the lower surface of the first rib 47 and the top of the household appliance 2 is less than the thickness of the accessory bag 5 reduces the possibility that the accessory bag 5 will detach from the top plate 4 under severe vibration; and reduces the possibility that the accessory bag 5 will slide out of the cavity 21 and become unstable after sliding from the lower surface of the first rib 47 and the top wall of the household appliance 2.

[0043] To further improve the stability of accessory bag 5 after placement, such as Figure 1 , Figure 2 and Figure 3As shown, the center of the lower surface of the top plate 4 is provided with a first rib 43. When the top plate 4 presses against the accessory bag 5, the first rib 43 presses against the middle position of the accessory bag 5, improving the stability of the accessory bag 5 after placement. Specifically, there are two first ribs 43 that are perpendicular to each other, increasing the range of pressing against the accessory bag 5 and improving the stability of the accessory bag 5.

[0044] In another embodiment, such as Figure 2 and Figure 4 As shown, the upper surface of the household appliance 2 has a second step 24, and a second rib 44 presses against the second step 24 and limits the accessory bag 5 to the inside of the second step 24. The lower surface of the top plate 4 is provided with a second rib 44, which is located on the outer periphery of the first rib 43. Figure 1 , Figure 2 and Figure 4 As shown, the first rib 43 abuts against the middle part of the accessory bag 5, and the second rib 44 blocks the outside of the accessory bag 5, improving the stability of the accessory bag 5 and preventing the accessory bag 5 from sliding out of the cavity 21 along the upper surface of the household appliance 2. Specifically, as... Figure 5 As shown, the inner end of the second rib 44 has a second inclined surface 441. The outer side of the second step 24 is inclined downwards and outwards along the center of the household appliance 2. The outer side of the second step 24 is parallel to the second inclined surface 441. After the accessory bag 5 and the top plate 4 are placed, when the second rib 44 presses against the second step 24, the second inclined surface 441 contacts and presses against the outer side of the second step 24, preventing the accessory bag 5 from sliding off the top of the second step 24. When the top of the household appliance 2 has a first step 23 and a second step 24, a V-shaped groove is formed between the first step 23 and the second step 24. At this time, the second rib 44 is located in the V-shaped groove between the first step 23 and the second step 24, and the second inclined surface 441 at the inner end of the second rib 44 abuts against the outer wall of the second step 24, thereby improving the stability of the accessory bag 5 and also improving the stability of the top plate 4 after placement.

[0045] In another embodiment, such as Figure 6 , Figure 7 and Figure 8 As shown, a first space 45 is formed between the first rib 43 and the top of the household appliance 2, with a height of H1. A second space 46 is formed between the second rib 44 and the top of the household appliance 2, with a height of H2. Specifically, the height of the first space 45 is set to be greater than the height of the second space 46, i.e., H1 > H2. The first rib 43 presses against the accessory bag 5, and the second rib 44 blocks the accessory bag 5 in the horizontal direction, further improving the stability of the accessory bag 5 after placement.

[0046] To facilitate the positioning and placement of the top plate 4, such as Figure 6As shown, the outer wall of the second step 24 is inclined, and the lower surface of the top plate 4 is provided with a second rib 49. The second rib 49 and the first rib 47 are respectively provided on different inner walls of the protrusion 42. After the first rib 47 is provided, the distance between the lower surface of the first rib 47 and the first inclined surface 231 is less than the thickness of the accessory bag 5 to ensure the stability of the accessory bag 5 under severe vibration. As for the second rib 49, the lower surface of the second rib 49 is inclined and parallel to the outer wall of the second step 24. After the top plate 4 is installed, the position of the top plate 4 is positioned by the contact between the lower surface of the second rib 49 and the outer side of the second step 24, which improves the stability of the top plate 4 after placement and ensures that the upper surface of the top plate 4 is parallel to the inner top wall of the box body 1 after pressing against the accessory bag 5, which facilitates subsequent sealing.

[0047] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
