[0064] In addition to protecting the side edges of household appliances such as the oven 100, the edge guard 400 also supports household appliances such as the oven 100 in the vertical direction. During the transportation of household appliances such as the oven 100, it prevents them from being squeezed after being subjected to vertical force, thereby providing more comprehensive protection for household appliances.
[0065] A corner recess is formed on the edge protection member 400 , and the corner recess is arranged outside the side edge of the oven 100 .
[0066] refer to Figure 9 The corner recess is located on the inner side of the edge guard 400. The cross-sectional shape of the edge guard 400 is specifically L-shaped. The upper connecting portion 210 and the lower connecting portion 310 are both L-shaped grooves formed at the corner positions of the upper support member 200 and the lower support member 300. When the edge guard 400 is installed with the upper support member 200 and the lower support member 300, the grooves at the corner positions of the upper support member 200 and the lower support member 300 are filled.
[0067] Among them, reference Figure 5 The top of the upper support member 200 is also provided with a receiving recess 220 , and the receiving recess 220 is used to place the accessories 110 of the oven 100 .

[0069] The shape of the accommodating recess 220 is specifically designed according to the shape of the accessory 110 to prevent the accessory 110 from colliding with the household appliance during transportation and causing damage. It also makes it more convenient for shippers and users to check the accessory 110, helping to avoid problems such as the loss or missing of the accessory 110.
[0070] Reference again Figure 2 In some embodiments of the present application, a bottom support plate 500 is further provided at the bottom of the lower support member 300, and an upward bent periphery 510 is formed on the peripheral side of the bottom support plate 500. The bottom of the lower support member 300 is connected to the bottom support plate 500, and the bottom of the edge guard member 400 is located on the inner side of the bent periphery 510.
[0071] The bottom support plate 500 can further support the lower support member 300 and facilitate the coordination between the packaging structure and the outer packaging box, resulting in a higher degree of fit.
[0072] In some embodiments of the present application, a pad 600 is further provided between the bottom support plate 500 and the lower support member 300 , and the bottom support plate 500 and the pad 600 are made of corrugated cardboard.
[0073] The pad 600 can further provide support and cushioning for the oven 100 and reduce vibration during transportation.
[0074] A support recess extending away from the oven 100 is formed on the lower contact surface of the lower support member 300 that contacts the oven 100 , and a support surface 360 is formed at the bottom of the support recess. The bottom of the oven 100 is supported on the support surface 360 .
[0075] In some embodiments of the present application, the upper support member 200 is formed with at least one through-going upper hollow portion 230, and / or
[0076] The lower support member 300 is formed with at least one penetrating lower hollow portion 330 .
[0077] Reference again Figure 5 、 Figure 7 In order to ensure the structural strength of the upper support member 200 and the lower support member 300, there are multiple upper hollow parts 230 and lower hollow parts 330, which are arranged on the upper support member 200 and the lower support member 300 in an array arrangement.
[0078] The hollowed-out portions on the upper support member 200 and / or the lower support member 300 can reduce the transmission of force, reduce the external force transmitted to household appliances such as the oven 100, act as a buffer, and ensure that the entire bottom of the product can be well protected when impacted.
[0079] In some embodiments, reference Figure 6 , Figure 7 A plurality of upper buffer grooves 250 are further formed on the upper contact surface of the upper support member 200 that contacts the top of the oven 100 , and the upper buffer grooves 250 are evenly arranged on the peripheral side of the upper hollow portion 230 .
[0080] Similarly, a plurality of lower buffer grooves 320 are also formed on the bottom surface of the lower support member 300 in contact with the pad 600 . The lower buffer grooves 320 are evenly arranged around the circumference of the lower hollow portion 330 .
[0081] In some embodiments of the present application, a door 120 is provided on the front side of the built-in oven 100, and an upwardly extending control panel 121 is formed above the door 120. The control panel 121 is used to facilitate the user to control the oven 100, and its upwardly extending structure can be used to cover the gap between the top of the oven 100 and the cabinet body to reduce dust entry and facilitate cleaning.
[0082] Specific reference Figure 6 A positioning recess 240 extending away from the oven 100 is formed on the upper contact surface of the upper support member 200 that contacts the top of the oven 100 , and the control panel 121 is at least partially positioned in the positioning recess 240 .
[0083] In other words, the oven 100 is provided with a door 120 on the front side, and the control panel 121 is located above the door 120. The control panel 121 is prone to collision during transportation. The positioning recess 240 on the upper contact surface can position and protect the control panel 121 to avoid collision of the control panel 121.
[0084] In some embodiments of the present application, a buffer groove portion 700 is formed on the outer periphery of the upper support member 200; and / or
[0085] A buffer groove portion 700 is formed on the outer periphery of the lower support member 300; and / or
[0086] A buffer groove 700 is formed on a sidewall of the positioning recess 240 .
[0087] The buffer groove 700 can reduce the transmission of external forces and make disassembly and assembly more convenient for operators and users.
[0088] refer to Figure 4 and Figure 8 In some embodiments of the present application, a downwardly extending corrugated protrusion 132 is formed on the bottom 130 of the box, and a conformal recess 340 that matches the position and shape of the corrugated protrusion 132 is formed on the lower contact surface of the lower support member 300 that contacts the oven 100, and the corrugated protrusion 132 is arranged in the corresponding conformal recess 340.
[0089] The shape of the pressed protrusions 132 is not limited. In order to ensure the stability of the oven 100 , in some embodiments, the pressed protrusions 132 are dispersedly arranged at the four corners near the bottom of the oven 100 .
[0090] In addition to supporting the oven 100, the corrugated protrusion 132 at the bottom of the oven 100 can also improve the structural strength of the bottom of the oven 100 and store condensed water. The conformal recess 340 is arranged corresponding to the corrugated protrusion 132, which can limit the position of the oven 100, reduce the shaking of the oven 100 during transportation, and make it more stable.
[0091] In some embodiments of the present application, the bottom 130 of the box is also formed with an upwardly extending airflow recess 131, which is close to the front side of the oven 100, and a positioning protrusion 350 is formed at the corresponding position of the lower support member 300, which extends into the airflow recess 131.
[0092] The air outlet of the built-in oven 100 is located on the bottom front side of the oven 100, and the air passage recess 131 is connected to the air outlet to facilitate the steam to be discharged from the air outlet to the outside through the air passage recess 131. The positioning protrusion 350 of the lower support 300 cooperates with the air passage recess 131 to play a limiting role, thereby facilitating the positioning of the oven 100 on the lower support 300 and reducing shaking during transportation.

[0094] Specifically, the inner protective layer 430 includes a first protective portion 431 and a second protective portion 432 arranged vertically, and the first protective portion 431 is fixed together by gluing or other means.
[0095] The middle supporting layer 420 includes a first supporting portion 421 and a second supporting portion 422 . The first supporting portion 421 and the second supporting portion 422 are also arranged vertically. The first supporting portion 421 and the second supporting portion 422 are also fixed together by gluing or other means.
[0096] The edge guard 400 provides support for the vertical direction of the packaging structure, thereby preventing the oven 100 and other household appliances from being squeezed during transportation, and enhancing the structural stability.
[0097] In other words, the edge guard 400 is made of three paper materials bonded together, and the outer protective layer 410, the inner protective layer 430 and the middle support layer 420 respectively provide pressure resistance, impact resistance, shock absorption, support and buffering functions. The combined effect will better protect the large-capacity, large-volume and heavy-weight oven 100 products.
[0098] The material of the upper support member 200 and the upper support member 200 is foam, and the entire packaging structure can provide good protection performance. On the basis of traditional foam packaging, a variety of environmentally friendly materials such as foam, corrugated cardboard, honeycomb cardboard, etc. are used to further improve the structural strength of the packaging structure, reduce damage to household appliances, and thus reduce maintenance costs.
