Description

Technical Field

[0001] This invention relates to cooking equipment, and more particularly to a side-opening door anti-sinking structure for cooking equipment. Background Technology

[0002] Currently, most built-in steam ovens on the market use a pull-down door structure. The pull-down door structure requires a large force to overcome the hinge force to open the door, which brings a poor user experience to customers. The side-opening structure of built-in steam ovens can be opened by simply turning the handle. However, considering that the door assembly of the steam oven is relatively heavy, after opening and closing the door for a long time, the door assembly is very likely to sink. The sinking of the door assembly will not only affect the appearance, but may even cause the door assembly to interfere with the bottom plate, making it impossible to open and close the door normally. Existing technologies disclose structures to prevent door sagging, such as the Chinese utility model patent CN202022523959.7 (authorization announcement number CN213657240U), which discloses "Anti-Door Sagging Structure and Refrigerator." This anti-sag structure is located at the lower end of the refrigerator body and includes a fixed part connected to the refrigerator body, a support plate connected to the fixed part and extending out of the refrigerator body, and a rolling element that cooperates with the free end of the door to support it. The rolling element is rotatably connected to the support plate, and its rotation direction is consistent with the movement direction of the free end of the door. When the door is closed, the rolling element cooperates with the free end of the door to support it, thus preventing the door from sagging due to its weight and ensuring the refrigerator body's airtightness and aesthetic appearance. Although this anti-sag structure has a certain anti-sag effect, its structural reliability is poor, and its anti-sag effect is generally limited. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a side-opening door anti-sinking structure for cooking equipment that can effectively prevent the side-opening door assembly from sinking after prolonged opening and closing, in view of the above-mentioned existing technology.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problem is: the side-opening anti-sinking structure of the cooking device includes a side-opening door body, characterized in that it further includes:

[0005] The bottom plate of the cabinet is located below the inner pot of the cooking equipment;

[0006] The front panel of the box is fixed to the front of the inner liner, and the bottom of the front panel of the box is fixed to the bottom panel of the box.

[0007] A hinge bracket is vertically installed on the left or right side of the inner liner and fixed to the front panel and bottom panel of the box.

[0008] The hinge support extends rearward through the front panel of the housing and is connected and fixed to the upper part of the hinge support bracket.

[0009] The lower hinge support extends backward through the front panel of the housing and is connected and fixed to the lower part of the hinge support bracket. The middle part of the lower hinge support forms a rotation fulcrum with the front panel of the housing. A fitting gap is left between the bottom rear end of the lower hinge support and the bottom panel of the housing. The bottom rear end of the lower hinge support is connected and fixed to the bottom panel of the housing so that the front end of the lower hinge support can be lifted upward.

[0010] An upper hinge is installed on the upper part of the door body, and the front part of the upper support of the hinge is rotatably connected to the upper hinge.

[0011] A lower hinge is installed at the lower part of the door body, and the front part of the lower hinge support is rotatably connected to the lower hinge.

[0012] There can be various rotating connection structures between the upper hinge and the upper hinge support. Preferably, the upper hinge support has an upper hinge shaft extending vertically downward, and the upper hinge has a vertically arranged upper shaft hole. The upper hinge shaft is inserted into the upper shaft hole so that the upper hinge can rotate relative to the upper hinge support.

[0013] Further preferably, the upper hinge shaft and the upper hinge form a shaft-hole clearance fit, and the clearance on one side is 0.02mm to 0.05mm. This appropriate clearance prevents the door assembly from sagging and avoids the phenomenon of the door assembly not rotating smoothly.

[0014] There can be various mating structures between the lower hinge support and the lower hinge. Preferably, the lower hinge support has a vertically arranged lower shaft hole, the lower hinge has a vertically arranged lower hinge shaft hole, the lower hinge shaft is vertically arranged, the lower end of the lower hinge shaft is inserted into the lower shaft hole, and the upper end of the lower hinge shaft is inserted into the lower hinge shaft hole.

[0015] Further preferably, the lower hinge shaft and the lower hinge are fitted with a clearance fit, while the lower hinge shaft and the lower hinge support are fitted with an interference fit. During assembly, the lower hinge shaft is forcibly pressed into the lower hinge hole to prevent relative rotation between the lower hinge shaft and the lower hinge support during the rotation of the door assembly.

[0016] Further optimized, the single-sided fitting clearance between the lower hinge shaft and the lower hinge is 0.02 to 0.05 mm, and the single-sided fitting clearance between the lower hinge shaft and the lower hinge support is -0.05 to 0 mm.

[0017] To further increase the structural strength of the hinge upper support, a hinge upper support fixing component is also included. The hinge upper support fixing component is fixed to the front plate of the housing by screws, and the rear end of the hinge upper support is fixed to the hinge upper support fixing component by screws.

[0018] To improve the structural strength of the upper and lower hinge supports, both the upper and lower hinge supports are fixed to the hinge bracket with screws, and the lower hinge support is fixed to the bottom plate of the housing with screws.

[0019] Further preferably, the hinge bracket has a "U"-shaped cross-section. The hinge bracket is fixed to the front panel of the housing with screws, and the hinge bracket is fixed to the bottom panel of the housing with screws. In this way, the hinge bracket will not twist, bend, or deform after bearing the force of the upper and lower hinge supports.

[0020] To improve the overall structural strength, the bottom of the inner liner is connected and fixed to the bottom plate of the box through an inner liner bracket, and the front plate of the box is connected and fixed to the inner liner with screws.

[0021] Compared with the prior art, the advantages of the present invention are as follows: the side-opening anti-sinking structure of the cooking device achieves the position fixation of the upper and lower hinge supports through the double fixing structure of the upper and lower hinge supports. Through the lever structure of the lower hinge support, the door assembly can be slightly lifted to prevent sinking. In addition, all related components are directly or indirectly connected and fixed to the bottom plate of the cabinet, forming a unified whole and increasing the overall structural strength.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 2 As shown, the cooking device in this embodiment adopts a side-opening door structure, so as to... Figure 2 The direction indicated by the middle arrow E is to the right, and door 1 adopts a side-opening structure that opens to the right.

[0034] like Figures 3 to 10 As shown, the side-opening anti-sinking structure of this cooking appliance includes components such as a door body 1, a bottom plate 2, a front plate 3, a hinge support bracket 4, an upper hinge support 5, a lower hinge support 6, an upper hinge 7, a lower hinge 8, a lower hinge shaft 9, and an upper hinge support fixing component 10. The bottom plate 2 is located below the inner pot 11 of the cooking appliance, and the bottom of the inner pot 11 is connected and fixed to the bottom plate 2 via an inner pot support bracket 12. The front plate 3 is located on the front side of the inner pot 11 and is connected and fixed to the inner pot 11 with screws. The bottom of the front plate 3 is connected and fixed to the bottom plate 2 with screws. Additionally, the side plates and rear plates are also connected and fixed to the bottom plate 2 with screws.

[0035] The hinge bracket 4 is vertically installed on the right side of the inner liner 11. The cross-section of the hinge bracket 4 is U-shaped. The hinge bracket 4 is fixed to the front panel 3 and the bottom panel 2 of the cabinet by screws. In this way, the hinge bracket 4 has high structural strength and will not be twisted, bent or deformed after bearing the force of the upper and lower hinge supports.

[0036] The rear part of the hinge upper support 5 passes through the front panel 3 of the housing and is fixed to the upper part of the hinge seat bracket 4 with screws. Furthermore, to improve the structural strength of the hinge upper support 5, the hinge upper support fixing member 10 is fixed to the front panel 3 of the housing with screws, and the rear end of the hinge upper support 5 is fixed to the hinge upper support fixing member 10 with screws. In this way, the hinge upper support 5 is fixed not only to the hinge seat bracket 4 but also to the front panel 3 of the housing, forming a double fixing structure. This ensures that the hinge upper support 5 will not shift position during the rotation of the door 1, thereby preventing the door 1 from sagging.

[0037] An upper hinge 7 is installed on the upper part of the door frame of door body 1, and the front part of the upper support 5 of the hinge is rotatably connected to the upper hinge. Specifically, as shown in... Figure 5As shown, the hinge support 5 has a vertically downward extending upper hinge shaft 51, and the upper hinge 7 has a vertically arranged upper shaft hole 71. The upper hinge shaft 51 is inserted into the upper shaft hole 71, allowing the upper hinge 7 to rotate relative to the hinge support 5. Furthermore, a shaft-hole clearance fit is formed between the upper hinge shaft 51 and the upper hinge 7, with a single-sided clearance of 0.02mm to 0.05mm. Therefore, a suitable amount of lubricating oil can be applied to the clearance between the upper hinge shaft 51 and the upper shaft hole 71 to ensure smooth rotation of the door 1, and this clearance also prevents the door 1 from sagging.

[0038] The rear of the lower hinge support 6 passes through the front panel 3 of the housing and is fixed to the lower part of the hinge bracket 4 with screws. A clearance of 0.25mm to 0.5mm is left between the bottom rear end of the lower hinge support 6 and the bottom plate 2 of the housing. Since the middle of the lower hinge support 6 forms a pivot point with the front panel 3, when the bottom rear end of the lower hinge support 6 is fixed to the bottom plate 2 with screws, in this embodiment, the lever arm of the lower hinge support 6 is approximately twice that of the front end. Therefore, due to the lever effect, the lower hinge support 6 can appropriately lift the door 1 by 0.5mm to 1mm, thus preventing the door 1 from sinking after repeated opening and closing. Furthermore, the lower hinge support 6 is fixed to both the hinge bracket 4 and the bottom plate 2 of the housing, forming a double-fixed structure to ensure that the lower hinge support 6 does not shift position during the rotation of the door 1, thereby preventing the door 1 from sinking.

[0039] A lower hinge 8 is installed on the lower part of the door frame of door body 1, and the front part of the lower hinge support 6 is rotatably connected to the lower hinge 8. Specifically, as shown in... Figure 6 As shown, the lower hinge support 6 has a vertically arranged lower shaft hole 61, the lower hinge 8 has a vertically arranged lower hinge shaft hole 81, and the lower hinge shaft 9 is vertically arranged. The lower end of the lower hinge shaft 9 is inserted into the lower shaft hole 61, and the upper end of the lower hinge shaft 9 is inserted into the lower hinge shaft hole 81. The lower hinge shaft 9 and the lower hinge 8 have a clearance fit, with a single-sided clearance of 0.02–0.05 mm. The lower hinge shaft 9 and the lower hinge support 6 have an interference fit, with a single-sided clearance of -0.05–0 mm. During assembly, a tooling is needed to force the lower hinge shaft 9 into the lower shaft hole 61 to prevent relative rotation between the lower hinge shaft 9 and the lower hinge support 6 during the rotation of the door body 1.

[0040] The side-opening door anti-sinking structure of this embodiment can be applied not only to commercial steam ovens, but also to other cooking equipment.
