Description

Technical Field

[0001] The present application relates to the technical field of electrode sheet drying, and in particular to a baking device. Background Art

[0002] In the manufacturing process of the battery electrode sheet, the electrode sheet is usually baked by a baking device to remove the residual solvent on the electrode sheet; during the baking process of the electrode sheet, the baking chamber needs to be evacuated to form a vacuum state in the baking chamber, thereby achieving the purpose of reducing the boiling point of the solvent and improving the drying efficiency of the electrode sheet.

[0003] In the related art, in order to enable the door body to withstand the pressure difference between the internal and external environments of the baking equipment, the baking equipment usually adopts a thick door body structure to reduce the risk of deformation or damage of the door body; however, during long-term use, the door body is prone to sinking or tilting due to its excessive weight, resulting in a reduction in the sealing effect of the door body on the baking chamber. Therefore, how to reduce the risk of sinking or tilting of the door body to improve the sealing effect of the door body on the baking chamber is a technical problem that needs to be urgently solved in this field. Utility Model Content

[0004] In view of the above problems, the present application provides a baking device to reduce the risk of the door body sinking or tilting, thereby improving the sealing effect of the door body on the baking cavity.

[0005] The present application provides a baking device, the baking device comprising: a box body, a baking cavity and an opening communicating with the baking cavity are formed; a door body, connected to the box body, and used to open or close the opening; a first support assembly, comprising a first support member and a second support member, the first support member is arranged on the box body, and the second support member is arranged on the door body, and when the door body is in a closed state, the second support member is supported on a side of the first support member close to the top of the box body. By arranging the first support member on the box body, arranging the second support member on the door body, and supporting the second support member on a side of the first support member close to the top of the box body when the door body is in a closed state, the second support member can transfer the gravity of the door body to the first support member, and then disperse it to the box body by the first support member, so as to realize the transfer of part of the gravity of the door body to the box body, which can not only reduce the risk of sinking or tilting of the door body due to excessive dead weight during long-term use, but also the gravity transferred from the door body to the box body will form pressure on the box body, so that the door body can fit closely with the box body, thereby improving the sealing effect of the door body on the baking cavity.

[0006] In some embodiments, the baking device further includes a hinge assembly. The hinge assembly is connected between the box body and the door body. The first support member is disposed on a side of the box body away from the hinge assembly, and the second support member is disposed on a side of the door body away from the hinge assembly. With such an arrangement, when the door body is in the closed state, the first support member and the second support member can support the side of the door body away from the hinge assembly, thereby reducing the risks such as sinking or tilting of the side of the door body away from the hinge assembly. Moreover, the first support member and the second support member can transfer part of the gravity of the door body to the box body. The gravity transferred from the door body to the box body not only forms a pressure on the box body, enabling the door body to fit tightly with the box body, but also can reduce the load on the hinge assembly, reduce the dependence of the door body on the hinge assembly, thereby reducing the risks such as damage to the hinge assembly due to long-term bearing of the entire load of the door body, and can extend the service life of the hinge assembly.

[0007] In some embodiments, the first support member is disposed on a side of the box body away from the top, and the second support member is disposed on a side of the door body away from the top. With such an arrangement, when the door body is in the closed state, the first support member and the second support member can support the bottom of the door body, reducing the risks such as overall sinking or tilting of the door body. Moreover, the first support member and the second support member can transfer part of the gravity of the door body to the box body. The gravity transferred from the door body to the box body not only forms a pressure on the box body, enabling the door body to fit tightly with the box body, but also can reduce the load on the hinge assembly, reduce the dependence of the door body on the hinge assembly, thereby reducing the risks such as damage to the hinge assembly due to long-term bearing of the entire load of the door body, and can extend the service life of the hinge assembly.

[0008] In some embodiments, one of the first support member and the second support member is provided with a first rolling portion, and the other of the first support member and the second support member is provided with a first bearing surface. When the door body is in the closed state, the first rolling portion is in contact with the first bearing surface. By providing the first rolling portion on one of the first support member and the second support member and the first bearing surface on the other of the first support member and the second support member, so that the first rolling portion can roll along the first bearing surface during the closing process of the door body and be in contact with the first bearing surface when the door body is in the closed state. On the one hand, it can reduce the friction between the first support member and the second support member, making the closing process of the door body smoother, thereby not only reducing the risks such as wear or deformation of the first support member and the second support member, but also reducing the impact force of the door body on the box body when the door body is closed, reducing the risks such as wear or deformation of the door body and the box body due to excessive impact force of the door body. On the other hand, the first rolling portion can convert the rolling friction between it and the first bearing surface into a supporting force for the door body, thereby reducing the risks such as sinking or tilting of the door body.

[0009] In some embodiments, the second support member is provided with a first rolling portion, and the first support member is provided with a first bearing surface and a guiding surface connecting the first bearing surface. The guiding surface is bent away from the top direction on the side of the first bearing surface away from the box body. The guiding surface can guide the first rolling portion to roll towards the first bearing surface during the closing process of the door body, so that the first rolling portion rolls smoothly onto the first bearing surface and is supported on the first bearing surface, realizing a smooth transition of the first rolling portion from the rolling state to the static support state, which can reduce the risks of collision or impact between the first rolling portion and the first support member, thereby reducing noise and structural wear, and contributing to extending the service life of the first support member and the second support member.

[0010] In some embodiments, one of the first support member and the second support member further includes: a first mounting seat including two first mounting portions arranged opposite and spaced apart; a first rotating shaft connected between the two first mounting portions; wherein, the first rolling portion includes a first rolling bearing sleeved outside the first rotating shaft, the axial direction of the first rolling bearing is parallel to the first bearing surface and perpendicular to the axial direction of the opening. By configuring the first rolling portion to include a first rolling bearing and making the axial direction of the first rolling bearing parallel to the first bearing surface and perpendicular to the axial direction of the opening, during the closing process of the door body, the first rolling bearing can roll on the first bearing surface along the axial direction of the opening. On the one hand, the movement track of the first rolling bearing is parallel to the axial direction of the opening, which helps to further reduce the frictional loss between the first support member and the second support member and makes the closing process of the door body more labor-saving; on the other hand, the first rolling bearing can bear the vertical gravity generated by the self-weight of the door body and transfer part of the gravity of the door body to the box body, which can effectively reduce the risks of the door body sinking or tilting due to excessive self-weight during long-term use.

[0011] In some embodiments, the door body includes: a door main body; a sealing plate connected to the side of the door main body close to the box body; a floating mechanism provided between the door main body and the sealing plate. By providing the floating mechanism between the door main body and the sealing plate, the floating mechanism can drive the sealing plate to float towards the box body when the door body is in the closed state and fit with the edge of the opening communicating with the baking cavity to seal the baking cavity, which can effectively improve the sealing effect and reliability of the door body on the baking cavity.

[0012] In some embodiments, the door body further includes a second support assembly. The second support assembly is disposed between the door main body and the sealing plate. The second support assembly is at least partially disposed on the sealing plate and is rollably supported on the door main body. By disposing the second support assembly at least partially on the sealing plate and rollably supporting it on the door main body, during the process of the floating mechanism driving the sealing plate to float, the second support assembly can roll along a preset track as the sealing plate floats. On the one hand, it can reduce the friction between the sealing plate and the door main body, not only improving the smoothness of the sealing plate floating but also reducing the risks of wear or deformation between the sealing plate and the door main body. On the other hand, the second support assembly can support the sealing plate, enabling the sealing plate to fit more closely and stably with the edge of the opening, and further improving the sealing effect of the door body on the baking chamber.

[0013] In some embodiments, the second support assembly includes: a third support member disposed on the side of the door main body facing the sealing plate; a fourth support member disposed on the side of the sealing plate facing the door main body. One of the third support member and the fourth support member is provided with a second rolling portion, and the other of the third support member and the fourth support member is provided with a second bearing surface. The second rolling portion is rollably abutted against the second bearing surface. With such a setting, during the process of the floating mechanism driving the sealing plate to float, the second rolling portion can roll on the second bearing surface as the sealing plate floats. On the one hand, it can reduce the friction between the sealing plate and the door main body, not only improving the smoothness of the sealing plate floating but also reducing the risks of wear or deformation between the sealing plate and the door main body. On the other hand, the third support member can support the sealing plate, and the fourth support member can transfer part of the gravity of the sealing plate to the door main body through the third support member, reducing the risks of deformation or sinking of the sealing plate during long-term floating, so that the sealing plate can fit more closely and stably with the edge of the opening, further improving the sealing effect of the door body on the baking chamber and being beneficial to extending the service life of the door body.

[0014] In some embodiments, one of the third support member and the fourth support member further includes: a second mounting seat including two relatively and spaced second mounting portions; a second rotating shaft connected between the two second mounting portions; wherein, the second rolling portion includes a second rolling bearing sleeved outside the second rotating shaft, the axial direction of the second rolling bearing is parallel to the second bearing surface and perpendicular to the arrangement direction of the door body and the sealing plate. By configuring the second rolling portion to include a second rolling bearing and making the axial direction of the second rolling bearing parallel to the second bearing surface and perpendicular to the arrangement direction of the door body and the sealing plate, during the process of the floating mechanism driving the sealing plate to float, the second rolling bearing can roll on the second bearing surface along the arrangement direction of the door body and the sealing plate. On the one hand, the movement track of the second rolling bearing is parallel to the floating direction of the sealing plate, which helps to further reduce the frictional loss between the third support member and the fourth support member, and can reduce the risk of jamming when the sealing plate floats, thereby effectively improving the smoothness of the sealing plate floating; on the other hand, the second rolling bearing can transfer part of the gravity of the sealing plate to the door body, and can reduce the risk of deformation or sinking of the sealing plate during long-term floating, so that the sealing plate can fit more closely and stably with the edge of the opening, which is beneficial to extending the service life of the door body.

[0015] In some embodiments, the second support assembly further includes a first fixing rod disposed on the side of the sealing plate facing the door body and extending along the axial direction of the second rolling bearing, and the fourth support member is disposed on the side of the first fixing rod close to the third support member. With such a setting, the bending strength of the sealing plate in the extending direction of the first fixing rod can be enhanced, and the risk of deformation of the sealing plate due to floating can be reduced.

[0016] In some embodiments, the floating mechanism includes an elastic component connected between the door body and the sealing plate, and the elastic component is used to provide a pressing force towards the box body for the sealing plate when the door body is in the closed state. With such a setting, the sealing plate floats towards the box body and fits closely with the edge of the opening, which can effectively improve the effect of the door body on the baking cavity; and, the elastic component can also automatically adjust the compression amount according to the flatness of the opening edge, which can effectively improve the sealing strength between the sealing plate and the opening edge.

[0017] In some embodiments, a receiving cavity is formed between the door body and the sealing plate, and the floating mechanism is disposed in the receiving cavity; the door body includes two side plates oppositely disposed on both sides of the receiving cavity; the floating mechanism further includes a second fixing rod connected between the two side plates, and the elastic component is disposed between the second fixing rod and the sealing plate. The second fixing rod can provide a stable supporting force for the elastic component and transfer part of the elastic restoring force generated when the elastic component contracts to the door body, reducing the risk of damage to the elastic component or uneven force on the sealing plate due to stress concentration at one end of the elastic component close to the door body.

[0018] In some embodiments, the elastic component includes: a positioning post, one end of the positioning post is fixed to the side of the second fixing rod facing the sealing plate, the other end extends towards the sealing plate and is spaced from the sealing plate; an elastic body, sleeved outside the positioning post, and one end of the elastic body abuts against the positioning post or the second fixing rod, and the other end abuts against the sealing plate. By arranging the positioning post on the side of the second fixing rod facing the sealing plate and sleeving the elastic body outside the positioning post, the positioning post can play a guiding role for the elastic body, so that the elastic body can be compressed or reset along the arrangement direction of the sealing plate and the door body, and the risk of lateral offset or distortion of the elastic body during compression or reset can be reduced, so that the floating trajectory of the sealing plate during the closing process of the door body is controllable, which can not only improve the stability of the sealing plate during floating, but also improve the sealing effect of the sealing plate; by arranging the positioning post to be spaced from the sealing plate, the space between the positioning post and the sealing plate can provide a contraction space for the elastic body to reduce the risk of failure of the elastic body to contract.

[0019] In some embodiments, the floating mechanism includes a plurality of second fixing rods, the plurality of second fixing rods extend along a first direction and are sequentially spaced along a second direction; wherein, a plurality of elastic components are provided between each second fixing rod and the sealing plate, and the plurality of elastic components are sequentially spaced along the first direction, the second direction is parallel to the arrangement direction of the top and bottom of the box body and perpendicular to the first direction. With such an arrangement, the plurality of elastic components can be dispersedly arranged at multiple positions between the sealing plate and the door body. On the one hand, the plurality of elastic components can automatically adjust the compression force according to the force condition, which can further improve the sealing effect of the sealing plate on the baking cavity; on the other hand, when a certain elastic component is fatigued or damaged, the remaining elastic components can also maintain the pressing force towards the box body for the sealing door, so that the door body has a fault tolerance ability, and the risk of air leakage in the baking cavity caused by the sealing door not being able to float towards the box body during the operation of the baking equipment can be reduced; on the other hand, the plurality of elastic components can jointly share the thrust of the box body towards the door body, which can relieve the fatigue aging speed of the elastic components and help to extend the service life of the door body.

[0020] In some embodiments, the door body further includes a limiting component, the limiting component is arranged between the door body and the sealing plate, and at least part of the limiting component extends to the side of the sealing plate facing away from the door body. The limiting component can limit the floating range of the sealing plate when the sealing plate floats towards the box body, and reduce the risks of the sealing plate tilting or being misaligned relative to the edge of the opening due to excessive floating displacement towards the box body, thereby reducing the possibility of sealing failure of the sealing plate.

[0021] In some embodiments, an avoidance groove is formed on one side of the sealing plate facing away from the door body; the limiting component includes: a fixing part disposed on the door body; a limiting body disposed on the side of the fixing part close to the sealing plate and at least partially extending into the avoidance groove. When the door body is in the open state, there is a gap between the limiting body and the bottom wall of the avoidance groove. By providing an avoidance groove on the side of the sealing plate facing away from the door body, extending the limiting body of the limiting component into the avoidance groove, and ensuring that there is a gap between the limiting body and the bottom wall of the avoidance groove when the door body is in the open state, the gap between the limiting body and the avoidance groove can provide a floating space for the sealing plate towards the box body during the closing process of the door body, enabling the sealing plate to float within the floating space defined by the limiting component.

[0038] In the manufacturing process of the electrode sheet of a battery, usually, an active material is first coated on the current collector surface of the electrode sheet by a coating device. The active material is usually a slurry. Since the slurry contains a solvent, the solvent will remain on the electrode sheet after coating the active material. The solvent will react with the electrolyte, resulting in corrosion of the electrode sheet, or causing gas generation and expansion inside the battery, affecting the stability of the battery. In order to remove the residual solvent on the electrode sheet, usually a baking device is used to bake the electrode sheet, and during the baking process, the baking chamber needs to be evacuated to make the baking chamber in a vacuum state, so as to achieve the purpose of reducing the boiling point of the solvent and improving the drying efficiency of the electrode sheet.

[0039] In the related art, in order to enable the door body to withstand the pressure difference between the internal and external environments of the baking device, the baking device usually adopts a heavy door body structure to reduce the risk of door body deformation or damage, etc.; however, during long-term use, the door body is prone to sink or tilt due to its excessive self-weight, resulting in a reduction in the sealing effect of the door body on the baking chamber.

[0040] Based on the above considerations, the present application provides a baking device. The baking device includes a box body, a door body, and a first support assembly. The box body is formed with a baking chamber and an opening communicating with the baking chamber; the door body is connected to the box body and is used to open or close the opening; the first support assembly includes a first support member and a second support member. The first support member is disposed on the box body, and the second support member is disposed on the door body. When the door body is in the closed state, the second support member supports on one side of the first support member close to the top of the box body. By disposing the first support member on the box body, disposing the second support member on the door body, and when the door body is in the closed state, supporting the second support member on one side of the first support member close to the top of the box body, the second support member can transfer the gravity of the door body to the first support member, and then the first support member disperses it to the box body, so as to realize transferring part of the gravity of the door body to the box body. This can not only reduce the risks of the door body sinking or tilting due to excessive self-weight during long-term use, but also the gravity transferred from the door body to the box body will form a pressure on the box body, so that the door body can be closely attached to the box body, thereby improving the sealing effect of the door body on the baking chamber.

[0041] The baking device of the embodiment of the present application is applicable to baking electrode sheets during the production process of batteries, and can at least reduce the risks of the door body sinking or tilting during long-term use, so as to improve the sealing effect of the door body on the baking chamber.

[0042] The electrode sheets dried by the baking device disclosed in the embodiment of the present application can be used in batteries, and the batteries can be used in electrical equipment using the battery as a power source or various energy storage systems using the battery as an energy storage element. The electrical equipment can be, but is not limited to, mobile phones, tablets, laptop computers, electric toys, electric tools, battery cars, electric vehicles, ships, spacecraft, and the like. Among them, the electric toys can include fixed or mobile electric toys, such as game consoles, electric vehicle toys, electric ship toys, and electric aircraft toys, etc., and the spacecraft can include airplanes, rockets, space shuttles, and spaceships, etc.

[0043] For the convenience of description, the following embodiments are described by taking a baking device of the embodiment of the present application as an example.

[0044] Please refer to Figures 1 to 3, the present application provides a baking device 1000. The baking device 1000 includes a box body 100, a door body 200, and a first support assembly 300. The box body 100 is formed with a baking cavity 100a and an opening 100b communicating with the baking cavity 100a; the door body 200 is connected to the box body 100 and is used to open or close the opening 100b; the first support assembly 300 includes a first support member 310 and a second support member 320. The first support member 310 is disposed on the box body 100, and the second support member 320 is disposed on the door body 200. When the door body 200 is in the closed state, the second support member 320 supports on one side of the first support member 310 close to the top of the box body 100.

[0045] Wherein, the box body 100 is formed with a baking cavity 100a and an opening 100b communicating with the baking cavity 100a. The door body 200 is connected to the side of the box body 100 where the opening 100b is provided to open or close the opening 100b. When the door body 200 is in the closed state, the door body 200 can close the opening 100b to seal the opening 100b, so that the baking cavity 100a is in a relatively closed state.

[0046] The first support member 310 can be disposed on the side wall 120 of the box body 100; or, the first support member 310 can also be disposed on the door frame 110 on the same side as the opening 100b and surrounding the opening 100b. The second support member 320 is disposed on the door body 200 and is correspondingly disposed with the first support member 310.

[0047] The top of the box body 100 is located on the upper side of the baking device 1000 along the gravity direction. Correspondingly, the bottom of the box body 100 is located on the lower side of the baking device 1000 along the gravity direction. The top and the bottom of the box body 100 are oppositely arranged along the gravity direction. When the body is in the closed state, the second support member 320 disposed on the door body 200 supports on one side of the first support member 310 disposed on the box body 100 close to the top of the box body 100. The projection of the second support member 320 towards the bottom of the box body 100 is at least partially located on the first support member 310, so that the second support member 320 can transfer the gravity of the door body 200 to the first support member 310.

[0048] The baking device 1000 may include a plurality of first support components 300. The plurality of first support components 300 may be disposed on a side of the baking device 1000 away from the hinge assembly 400, that is, the plurality of first support members 310 are disposed on a side of the cabinet 100 away from the hinge assembly 400, and are sequentially arranged at intervals along the arrangement direction of the top and bottom of the cabinet 100. The plurality of second support members 320 are disposed on a side of the door body 200 away from the hinge assembly 400, and when the door body 200 is in the closed state, the plurality of second support members 320 are supported on a side of the corresponding first support member 310 close to the top of the cabinet 100; alternatively, the plurality of first support components 300 may also be disposed on a side of the baking device 1000 away from the top, that is, the plurality of first support members 310 are disposed on a side of the cabinet 100 away from the top, and are sequentially arranged at intervals along a direction perpendicular to the arrangement direction of the top and bottom. The plurality of second support members 320 are disposed on a side of the door body 200 away from the top of the cabinet 100, and when the door body 200 is in the closed state, the plurality of second support members 320 are supported on a side of the corresponding first support member 310 close to the top of the cabinet 100; alternatively, a part of the plurality of first support components 300 may be disposed on a side of the baking device 1000 away from the hinge assembly 400, and another part may be disposed on a side of the baking device 1000 away from the hinge assembly 400.

[0049] By disposing the first support member 310 on the cabinet 100, disposing the second support member 320 on the door body 200, and when the door body 200 is in the closed state, supporting the second support member 320 on a side of the first support member 310 close to the top of the cabinet 100, the second support member 320 can transfer the gravity of the door body 200 to the first support member 310, and then the first support member 310 disperses it to the cabinet 100, so as to realize transferring part of the gravity of the door body 200 to the cabinet 100. This can not only reduce the risks such as sinking or tilting of the door body 200 due to excessive self-weight during long-term use, but also the gravity transferred from the door body 200 to the cabinet 100 will form a pressure on the cabinet 100, so that the door body 200 can be closely attached to the cabinet 100, thereby improving the sealing effect of the door body 200 on the baking chamber 100a.

[0050] In some embodiments, please continue to refer to Figures 1 to 2 , the baking device 1000 further includes a hinge assembly 400. The hinge assembly 400 is connected between the cabinet 100 and the door body 200. The first support member 310 is disposed on a side of the cabinet 100 away from the hinge assembly 400, and the second support member 320 is disposed on a side of the door body 200 away from the hinge assembly 400.

[0051] The door body 200 is connected to the box body 100 through the hinge assembly 400. The hinge assembly 400 can not only provide the rotation function for the door body 200, so that the door body 200 can rotate relative to the box body 100, facilitating the opening or closing of the opening 100b by the door body 200; but also provide the supporting force for the door body 200, so that the door body 200 will not fall or shake during the opening and closing processes, improving the reliability of the door body 200.

[0052] The first support member 310 can be arranged on the side wall 120 of the box body 100 on the side far from the hinge assembly 400; or, the first support member 310 can be arranged on the door frame 110 of the box body 100 on the side far from the hinge assembly 400. The second support member 320 can be arranged on the end of the door body 200 far from the hinge assembly 400.

[0053] By arranging the first support member 310 on the side of the box body 100 far from the hinge assembly 400 and arranging the second support member 320 on the side of the door body 200 far from the hinge assembly 400, when the door body 200 is in the closed state, the first support member 310 and the second support member 320 can support the side of the door body 200 far from the hinge assembly 400, thereby reducing the risks such as sinking or tilting of the side of the door body 200 far from the hinge assembly 400; and, the first support member 310 and the second support member 320 can transfer part of the gravity of the door body 200 to the box body 100. The gravity transferred from the door body 200 to the box body 100 will not only form a pressure on the box body 100, making the door body 200 closely fit with the box body 100, but also reduce the load of the hinge assembly 400, reduce the dependence of the door body 200 on the hinge assembly 400, thereby reducing the risks such as damage of the hinge assembly 400 due to long-term bearing of all the loads of the door body 200, and prolonging the service life of the hinge assembly 400.

[0054] In some embodiments, the first support member 310 is arranged on the side of the box body 100 far from the top, and the second support member 320 is arranged on the side of the door body 200 far from the top of the box body 100.

[0055] The first support member 310 can be arranged on the door frame 110 on the side of the box body 100 far from the top, and the second support member 320 is arranged on the end on the side of the door body 200 far from the top of the box body 100.

[0056] By arranging the first support member 310 on a side of the box body 100 away from the top, and arranging the second support member 320 on a side of the door body 200 away from the top of the box body 100, when the door body 200 is in the closed state, the first support member 310 and the second support member 320 can support the bottom of the door body 200, and can reduce risks such as the overall sinking or tilting of the door body 200; moreover, the first support member 310 and the second support member 320 can transfer part of the gravity of the door body 200 to the box body 100. The gravity transferred from the door body 200 to the box body 100 will not only form a pressure on the box body 100, enabling the door body 200 to be closely attached to the box body 100, but also can reduce the load on the hinge assembly 400, reduce the dependence of the door body 200 on the hinge assembly 400, thereby reducing the risk of damage to the hinge assembly 400 due to long-term bearing of all the loads of the door body 200, and can extend the service life of the hinge assembly 400.

[0057] In some embodiments, please continue to refer to Figure 3 , one of the first support member 310 and the second support member 320 is provided with a first rolling portion 321. The other of the first support member 310 and the second support member 320 is provided with a first bearing surface 311. When the door body 200 is in the closed state, the first rolling portion 321 is in contact with the first bearing surface 311.

[0058] Wherein, when the first rolling portion 321 is arranged on the first support member 310, the first bearing surface 311 is arranged on the second support member 320, and the first rolling portion 321 is located on a side of the first support member 310 close to the top of the box body 100, and the first bearing surface 311 is located on a side of the second support member 320 away from the top of the box body 100; when the first rolling portion 321 is arranged on the second support member 320, the first bearing surface 311 is arranged on the first support member 310, and the first rolling portion 321 is located on a side of the second support member 320 away from the top of the box body 100, and the first bearing surface 311 is located on a side of the first support member 310 close to the top of the box body 100.

[0059] During the closing process of the door body 200, when the door body 200 is closed to a set angle, the first rolling portion 321 can contact the first bearing surface 311 and roll along the first bearing surface 311. Since rolling friction is generated between the first rolling portion 321 and the first bearing surface 311 during rolling, the friction between the second support member 320 and the first support member 310 can be reduced; when the door body 200 is in the closed state, that is, when the door body 200 is closed in place, the side of the door body 200 close to the box body 100 is attached to the box body 100, which can prevent the first rolling portion 321 from continuing to roll along the first bearing surface 311, so that the first rolling portion 321 abuts against the first bearing surface 311, thereby converting the rolling friction between the first rolling portion 321 and the first bearing surface 311 into a supporting force for the door body 200.

[0060] By providing a first rolling part 321 on one of the first support member 310 and the second support member 320, and providing a first bearing surface 311 on the other of the first support member 310 and the second support member 320, so that the first rolling part 321 can roll along the first bearing surface 311 during the closing process of the door body 200 and abut against the first bearing surface 311 when the door body 200 is in the closed state. On the one hand, the frictional force between the first support member 310 and the second support member 320 can be reduced, making the closing process of the door body 200 smoother. Thus, not only can the risks of wear or deformation of the first support member 310 and the second support member 320 be reduced, but also the impact force on the cabinet 100 when the door body 200 is closed can be reduced, and the risks of wear or deformation of the door body 200 and the cabinet 100 caused by excessive impact force of the door body 200 can be reduced. On the other hand, the first rolling part 321 can convert the rolling friction between it and the first bearing surface 311 into a supporting force for the door body 200, thereby reducing the risks of the door body 200 sinking or tilting, etc.

[0061] In some embodiments, please continue to refer to Figure 3 , the second support member 320 is provided with a first rolling part 321, the first support member 310 is provided with a first bearing surface 311 and a guiding surface 312, and the guiding surface 312 is bent and arranged from the side of the first bearing surface 311 away from the cabinet 100 towards the direction away from the top of the cabinet 100.

[0062] Wherein, the guiding surface 312 is connected to the side of the first bearing surface 311 away from the cabinet 100, and is bent and arranged from the side of the first bearing surface 311 away from the cabinet 100 towards the direction away from the top of the cabinet 100. The guiding surface 312 can be used as the front end extension part of the first bearing surface 311, and can be used to guide the first rolling part 321 to roll towards the first bearing surface 311 during the closing process of the door body 200, so that the first rolling part 321 abuts against the first bearing surface 311 and is supported on the first bearing surface 311.

[0063] In some embodiments, the first rolling part 321 is arranged on the first support member 310, the first bearing surface 311 and the guiding surface 312 are arranged on the second support member 320, and the guiding surface 312 is bent and arranged from the side of the first bearing surface 311 away from the cabinet 100 towards the direction close to the top of the cabinet 100.

[0064] In some embodiments, the connection between the guiding surface 312 and the first bearing surface 311 is smoothly arranged, which can not only enable the first rolling part 321 to smoothly pass through the connection between the guiding surface 312 and the first bearing surface 311, but also relieve or eliminate the vibration during the process of the first rolling part 321 rolling from the guiding surface 312 to the first bearing surface 311, contributing to improving the stability of the door body 200 during the closing process.

[0065] By arranging the first bearing surface 311 and the guiding surface 312 on the first support member 310, and the guiding surface 312 is bent from the side of the first bearing surface 311 away from the cabinet 100 towards the direction away from the top of the cabinet 100, the guiding surface 312 can guide the first rolling part 321 to roll towards the first bearing surface 311 during the closing process of the door body 200, so that the first rolling part 321 rolls smoothly onto the first bearing surface 311 and is supported on the first bearing surface 311, realizing a smooth transition of the first rolling part 321 from the rolling state to the static support state, which can reduce the risks of collision or impact between the first rolling part 321 and the first support member 310, thereby reducing noise and structural wear, and contributing to extending the service life of the first support member 310 and the second support member 320.

[0066] In some embodiments, please continue to refer to Figure 3 , one of the first support member 310 and the second support member 320 further includes a first mounting seat 322 and a first rotating shaft 324, the first mounting seat 322 includes two first mounting parts 323 which are opposite and spaced apart; the first rotating shaft 324 is connected between the two first mounting parts 323; wherein, the first rolling part 321 includes a first rolling bearing 3211, the first rolling bearing 3211 is sleeved outside the first rotating shaft 324, the axial direction of the first rolling bearing 3211 is parallel to the first bearing surface 311, and perpendicular to the axial direction of the opening 100b.

[0067] Wherein, one of the first support member 310 and the second support member 320 is the one with the first rolling part 321 among the first support member 310 and the second support member 320. For the convenience of description, in the following embodiments, the one with the first rolling part 321 is taken as the second support member 320, the second support member 320 is arranged on the side of the door body 200 away from the hinge assembly 400, and the first support member 310 is arranged on the side of the cabinet 100 away from the hinge assembly 400 as an example for description.

[0068] The second support member 320 includes a first mounting base 322 and a first rotating shaft 324. The first mounting base 322 is fixed to the side of the door body 200 away from the hinge assembly 400 and extends at least partially in a direction away from the hinge assembly 400. Two first mounting portions 323 are provided on the portion of the first mounting base 322 that extends in the direction away from the hinge assembly 400. The two first mounting portions 323 are spaced apart along the arrangement direction of the side of the door body 200 connected to the hinge assembly 400 and the side provided with the second support member 320, and the two first mounting portions 323 are formed with corresponding shaft holes. Both ends of the first rotating shaft 324 are fixed in the shaft holes of the corresponding first mounting portions 323. The first rolling bearing 3211 is sleeved outside the first rotating shaft 324 and can rotate along the circumferential direction of the first rotating shaft 324. The axial direction of the first rolling bearing 3211 is parallel to the first bearing surface 311 and perpendicular to the axial direction of the opening 100b; wherein, the axial direction of the opening 100b is parallel to the arrangement direction of the door body 200 and the box body 100 when the door body 200 is in the closed state.

[0069] The fixing method of the first mounting base 322 to the door body 200 can be welding, riveting, bolt connection, magnetic adsorption connection or adhesive connection, but is not limited thereto.

[0070] By configuring the first rolling portion 321 to include the first rolling bearing 3211 and making the axial direction of the first rolling bearing 3211 parallel to the first bearing surface 311 and perpendicular to the axial direction of the opening 100b, during the closing process of the door body 200, the first rolling bearing 3211 can roll on the first bearing surface 311 along the axial direction of the opening 100b. On the one hand, the movement track of the first rolling bearing 3211 is parallel to the axial direction of the opening 100b, which helps to further reduce the frictional loss between the first support member 310 and the second support member 320 and makes the closing process of the door body 200 more labor-saving; on the other hand, the first rolling bearing 3211 can bear the vertical gravity generated by the self-weight of the door body 200 and transfer part of the gravity of the door body 200 to the box body 100, which can effectively reduce the risk of the door body 200 sinking or tilting due to excessive self-weight during long-term use.

[0071] In some embodiments, please refer to Figure 4 , the door body 200 includes a door main body 210, a sealing plate 220 and a floating mechanism 230. The sealing plate 220 is connected to the side of the door main body 210 close to the box body 100. The floating mechanism 230 is arranged between the door main body 210 and the sealing plate 220.

[0072] Wherein, when the door body 200 is in the closed state, the sealing plate 220 is located on the side of the door main body 210 close to the box body 100.

[0073] The door body 210 can serve as a rigid frame of the door 200, and the door body 210 can provide a certain rigid support for the sealing plate 220. The material of the door body 210 can be selected from metals with high strength, high temperature resistance, anti-deformation and other properties such as high temperature resistant stainless steel, aluminum alloy, etc., but not limited thereto.

[0074] The sealing plate 220 can serve as a sealing structure of the door 200. The material of the sealing plate 220 can be selected from non-metals or metals with properties such as high temperature resistance and flexibility, such as polyimide, polyether ether ketone, and stainless steel, but not limited thereto. When the material of the sealing plate 220 can be selected from stainless steel, the surface of the sealing plate 220 can be polished, or an elastic seal can be provided on the side of the sealing plate 220 facing the box body 100.

[0075] During the closing process of the door 200, when the side of the sealing plate 220 facing away from the door body 210 contacts the edge of the opening 100b, the edge of the opening 100b will generate a thrust on the floating mechanism 230 to trigger the floating mechanism 230 to drive the sealing plate 220 to float towards the box body 100. When the door 200 is opened, the thrust of the edge of the opening 100b on the floating mechanism 230 disappears, and the floating mechanism 230 returns to its natural state and drives the sealing plate 220 to float towards the door body 210. Among them, the edge of the opening 100b can be a part of the box body 100 around the opening 100b, or can be the door frame 110.

[0076] By arranging the floating mechanism 230 between the door body 210 and the sealing plate 220, the floating mechanism 230 can drive the sealing plate 220 to float towards the box body 100 when the door 200 is in the closed state, and fit with the edge of the opening 100b communicating with the baking cavity 100a to seal the baking cavity 100a, which can effectively improve the sealing effect and reliability of the door 200 on the baking cavity 100a.

[0077] In some embodiments, please continue to refer to Figure 4 , the door 200 further includes a second support assembly 250. The second support assembly 250 is arranged between the door body 210 and the sealing plate 220. The second support assembly 250 is at least partially arranged on the sealing plate 220 and is rollably supported on the door body 210.

[0078] The second support assembly 250 is supported on the door body 210, and during the process of the floating mechanism 230 driving the sealing plate 220 to float, the second support assembly 250 can roll along a preset track as the sealing plate 220 floats. Specifically, when the floating mechanism 230 drives the sealing plate 220 to float towards the box body 100 and when the floating mechanism 230 drives the sealing plate 220 to float towards the door body 210, the second support assembly 250 can roll along a preset track as the sealing plate 220 floats.

[0079] By disposing the second support assembly 250 at least partially on the sealing plate 220 and rollably supporting the door body 210, during the process of the floating mechanism 230 driving the sealing plate 220 to float, the second support assembly 250 can roll along a preset track as the sealing plate 220 floats. On the one hand, the friction between the sealing plate 220 and the door body 210 can be reduced, which can not only improve the smoothness of the floating of the sealing plate 220, but also reduce the risks such as wear or deformation between the sealing plate 220 and the door body 210. On the other hand, the second support assembly 250 can support the sealing plate 220, so that the sealing plate 220 can fit more closely and stably with the edge of the opening 100b, and can further improve the sealing effect of the door body 200 on the baking cavity 100a.

[0080] In some embodiments, please continue to refer to Figure 4 and, at the same time, refer to Figures 5 to 6 The second support assembly 250 includes a third support member 251 and a fourth support member 252. The third support member 251 is disposed on the side of the door body 210 facing the sealing plate 220. The fourth support member 252 is disposed on the side of the sealing plate 220 facing the door body 210. Wherein, one of the third support member 251 and the fourth support member 252 is provided with a second rolling portion 2521, and the other of the third support member 251 and the fourth support member 252 is provided with a second bearing surface 2511, and the second rolling portion 2521 is rollably abutted against the second bearing surface 2511.

[0081] Wherein, the arrangement direction of the third support member 251 and the fourth support member 252 is parallel to the arrangement direction of the top and bottom of the box body 100. Along the arrangement direction of the top and bottom of the box body 100, the fourth support member 252 disposed on the sealing plate 220 is closer to the top of the box body 100 than the third support member 251 disposed on the door body 210, so that the fourth support member 252 can support on the third support member 251.

[0082] When the second rolling portion 2521 is disposed on the third support member 251, the second bearing surface 2511 is disposed on the fourth support member 252; when the second rolling portion 2521 is disposed on the fourth support member 252, the second bearing surface 2511 is disposed on the third support member 251. The second rolling portion 2521 is rollably abutted against the second bearing surface 2511. During the process of the floating mechanism 230 driving the sealing plate 220 to float, the second rolling portion 2521 can roll on the second bearing surface 2511 as the sealing plate 220 floats.

[0083] By providing a second rolling part 2521 on one of the third support member 251 and the fourth support member 252, and a second bearing surface 2511 on the other of the third support member 251 and the fourth support member 252, during the process of the floating mechanism 230 driving the sealing plate 220 to float, the second rolling part 2521 can roll on the second bearing surface 2511 as the sealing plate 220 floats. On the one hand, it can reduce the frictional force between the sealing plate 220 and the door body 210, which can not only improve the smoothness of the floating of the sealing plate 220, but also reduce the risks such as wear or deformation between the sealing plate 220 and the door body 210. On the other hand, the third support member 251 can support the sealing plate 220, and the fourth support member 252 can transfer part of the gravity of the sealing plate 220 to the door body 210 through the third support member 251, which can reduce the risks such as deformation or sinking of the sealing plate 220 during long-term floating, so that the sealing plate 220 can fit more closely and stably with the edge of the opening 100b, which can further improve the sealing effect of the door body 200 on the baking cavity 100a and is beneficial to extending the service life of the door body 200.

[0084] In some embodiments, one of the third support member 251 and the fourth support member 252 further includes a second mounting seat 2522 and a second rotating shaft 2524. The second mounting seat 2522 includes two relatively and spaced second mounting parts 2523, and the second rotating shaft 2524 is connected between the two second mounting parts 2523. Wherein, the second rolling part 2521 includes a second rolling bearing 2521a, and the second rolling bearing 2521a is sleeved outside the second rotating shaft 2524. The axial direction of the second rolling bearing 2521a is parallel to the second bearing surface 2511 and perpendicular to the arrangement direction of the door body 210 and the sealing plate 220.

[0085] Wherein, one of the third support member 251 and the fourth support member 252 is the one provided with the second rolling part 2521 among the third support member 251 and the fourth support member 252. For the convenience of description, in the following embodiments, the one provided with the second rolling part 2521 is taken as the fourth support member 252 as an example for description.

[0086] The fourth support member 252 includes a second mounting seat 2522 and a second rotating shaft 2524. The second mounting seat 2522 is fixed to the side of the sealing plate 220 facing the door body 210 and extends at least partially in the direction towards the third support member 251. Two second mounting portions 2523 are provided on the portion of the second mounting seat 2522 extending in the direction towards the third support member 251. The two second mounting portions 2523 are spaced apart along the arrangement direction of the side of the door body 200 where the hinge assembly 400 is connected and the side where the second support member 320 is provided, and the two second mounting portions 2523 are formed with corresponding shaft holes. Both ends of the second rotating shaft 2524 are fixed in the shaft holes of the corresponding second mounting portions 2523. The second rolling bearing 2521a is sleeved outside the second rotating shaft 2524 and can rotate circumferentially along the second rotating shaft 2524. The axial direction of the second rolling bearing 2521a is parallel to the second bearing surface 2511 and perpendicular to the arrangement direction of the door body 210 and the sealing plate 220; wherein, the arrangement direction of the door body 210 and the sealing plate 220 is also the floating direction of the sealing plate 220.

[0087] By configuring the second rolling part 2521 to include the second rolling bearing 2521a and making the axial direction of the second rolling bearing 2521a parallel to the second bearing surface 2511 and perpendicular to the arrangement direction of the door body 210 and the sealing plate 220, during the process of the floating mechanism 230 driving the sealing plate 220 to float, the second rolling bearing 2521a can roll on the second bearing surface 2511 along the arrangement direction of the door body 210 and the sealing plate 220. On the one hand, the movement track of the second rolling bearing 2521a is parallel to the floating direction of the sealing plate 220, which helps to further reduce the frictional loss between the third support member 251 and the fourth support member 252, and can reduce the risk of jamming when the sealing plate 220 floats, thereby effectively improving the smoothness of the floating of the sealing plate 220; on the other hand, the second rolling bearing 2521a can transfer part of the gravity of the sealing plate 220 to the door body 210, and can reduce the risk of deformation or sinking of the sealing plate 220 during long-term floating, so that the sealing plate 220 can fit more closely and stably with the edge of the opening 100b, which is beneficial to extending the service life of the door body 200.

[0088] In some embodiments, the second support assembly 250 further includes a first fixing rod 253. The first fixing rod 253 is disposed on the side of the sealing plate 220 facing the door body 210 and extends along the axial direction of the second rolling bearing 2521a. The fourth support member 252 is disposed on the side of the first fixing rod 253 close to the third support member 251.

[0089] Wherein, the first fixing rod 253 extends along the axial direction of the second rolling bearing 2521a, that is, the extending direction of the first fixing rod 253 is perpendicular to the floating direction of the sealing plate 220.

[0090] The first fixing rod 253 can be fixed to the sealing plate 220 by means of welding, bolt connection, riveting, snap connection, etc.

[0091] The fourth support member 252 can be integrally formed on the first fixing rod 253; or can be arranged on the first fixing rod 253 by a fixed connection method. Among them, the fixed connection method can be welding, bolt connection, riveting, snap connection, etc., but is not limited thereto.

[0092] By arranging the first fixing rod 253 on the side of the sealing plate 220 facing the door body 210, and the first fixing rod 253 extends along the axial direction of the second rolling bearing 2521a, the bending strength of the sealing plate 220 in the extending direction of the first fixing rod 253 can be enhanced, and the risk of deformation of the sealing plate 220 due to floating can be reduced.

[0093] The door body 200 can include a plurality of second support assemblies 250. The fourth support members 252 in the plurality of second support assemblies 250 are all arranged on the side of the first fixing rod 253 close to the third support member 251, and the fourth support members 252 of the plurality of second support assemblies 250 are arranged at intervals in sequence along the extending direction of the first fixing rod 253. The number of the second support assemblies 250 can be two, three, five, six, eight, etc., but is not limited thereto. The specific number of the second support assemblies 250 can be selected according to the size of the first fixing rod 253 along its extending direction. By arranging a plurality of second support assemblies 250, not only can the smoothness of the floating of the sealing plate 220 be further improved, but also the gravity of the sealing plate 220 can be dispersed along the axial direction of the second rolling bearing 2521a to multiple areas of the door body 210, and the risk of local stress concentration can be reduced.

[0094] In some embodiments, please continue to refer to Figure 4 and Figure 6 , the floating mechanism 230 includes an elastic component 231. The elastic component 231 is connected between the door body 210 and the sealing plate 220. The elastic component 231 is used to provide a pressing force towards the box body 100 for the sealing plate 220 when the door body 200 is in the closed state.

[0095] During the closing process of the door body 200, the side of the sealing plate 220 facing away from the door main body 210 first contacts the edge of the opening 100b. As the door body 200 continues to close, a thrust force towards the sealing plate 220 will be generated at the edge of the opening 100b, causing the elastic component 231 to contract and generate an elastic restoring force towards the box body 100. The elastic restoring force can be converted into a pressing force of the sealing plate 220 towards the box body 100, enabling the sealing plate 220 to float towards the box body 100 and closely fit with the edge of the opening 100b, effectively improving the sealing effect of the door body 200 on the baking cavity 100a. When the door body 200 is in the closed state, the edge of the opening 100b will provide a continuous thrust force to the sealing plate 220, causing the elastic component 231 to be in a continuously compressed state, continuously providing a pressing force of the sealing plate 220 towards the box body 100.

[0096] During the opening process of the door body 200, the thrust force of the edge of the opening 100b towards the sealing plate 220 disappears, and the elastic component 231 restores its elastic deformation as the thrust force disappears, driving the sealing plate 220 to float towards the door main body 210.

[0097] By connecting the elastic component 231 between the door main body 210 and the sealing plate 220, the elastic component 231 can provide a pressing force of the sealing plate 220 towards the box body 100 when the door body 200 is in the closed state, enabling the sealing plate 220 to float towards the box body 100 and closely fit with the edge of the opening 100b, effectively improving the sealing effect of the door body 200 on the baking cavity 100a; moreover, the elastic component 231 can also automatically adjust the compression amount according to the flatness of the edge of the opening 100b, effectively improving the sealing strength between the sealing plate 220 and the edge of the opening 100b.

[0098] In some embodiments, please continue to refer to Figure 4 and Figure 6 , a receiving cavity 200a is formed between the door main body 210 and the sealing plate 220. The floating mechanism 230 is arranged in the receiving cavity 200a. The door body 200 includes two side plates 240 oppositely arranged on both sides of the receiving cavity 200a. The floating mechanism 230 further includes a second fixing rod 232, the second fixing rod 232 is connected between the two side plates 240, and the elastic component 231 is arranged between the second fixing rod 232 and the sealing plate 220.

[0099] Wherein, the two side plates 240 can be a part of the door main body 210; or, the two side plates 240 can also be a structure independent of the door main body 210, used to seal the receiving cavity 200a between the door main body 210 and the sealing plate 220.

[0100] Among them, the extending direction of the second fixing rod 232 can be parallel to the extending direction of the first fixing rod 253, so that the first fixing rod 253 and the second fixing rod 232 do not interfere with each other structurally.

[0101] By connecting the second fixing rod 232 between the two side plates 240 and arranging the elastic component 231 between the second fixing rod 232 and the sealing plate 220, the second fixing rod 232 can provide a stable supporting force for the elastic component 231 and transfer part of the elastic restoring force generated when the elastic component 231 contracts to the door body 210, reducing the risks such as damage to the elastic component 231 or uneven force on the sealing plate 220 caused by stress concentration at one end of the elastic component 231 close to the door body 210.

[0102] In some embodiments, please continue to refer to Figure 6 , the elastic component 231 includes a positioning post 2311 and an elastic body 2312. One end of the positioning post 2311 is fixed to the side of the second fixing rod 232 facing the sealing plate 220, the other end extends towards the sealing plate 220, and is spaced from the sealing plate 220. The elastic body 2312 is sleeved outside the positioning post 2311, and one end of the elastic body 2312 abuts against the positioning post 2311 or the second fixing rod 232, and the other end abuts against the sealing plate 220.

[0103] The positioning post 2311 can be integrally formed on the side of the second fixing rod 232 facing the sealing plate 220; or fixed to the side of the second fixing rod 232 facing the sealing plate 220 by a fixed connection method, where the fixed connection method can be welding, adhesive connection, etc., but is not limited thereto.

[0104] In some embodiments, the positioning post 2311 can include a base and a positioning body. Among them, the base is fixed to the side of the second fixing rod 232 facing the sealing plate 220, the positioning body extends from the side of the base facing the sealing plate 220 towards the sealing plate 220, and the end of the positioning body close to and away from the base is spaced from the sealing plate 220. Of course, the positioning post 2311 can also only include the positioning body, one end of the positioning body is fixed to the side of the second fixing rod 232 facing the sealing plate 220, the other end extends towards the sealing plate 220, and is spaced from the sealing plate 220.

[0105] If the positioning post 2311 includes a base and a positioning body, then, one end of the elastic body 2312 abuts against the side of the base facing the sealing plate 220, and the other end abuts against the sealing plate 220. If the positioning post 2311 only includes the positioning body, then, one end of the elastic body 2312 abuts against the second fixing rod 232, and the other end abuts against the sealing plate 220.

[0106] The elastic body 2312 can be a spring.

[0107] By arranging a positioning post 2311 on one side of the second fixing rod 232 facing the sealing plate 220 and sleeving the elastic body 2312 outside the positioning post 2311, the positioning post 2311 can guide the elastic body 2312, enabling the elastic body 2312 to be compressed or reset along the arrangement direction of the sealing plate 220 and the door body 210. This can reduce the risks such as lateral offset or distortion of the elastic body 2312 during compression or reset, so that the floating trajectory of the sealing plate 220 is controllable during the closing process of the door body 200. This can not only improve the stability of the sealing plate 220 during floating, but also improve the sealing effect of the sealing plate 220. By arranging the positioning post 2311 at an interval from the sealing plate 220, the interval between the positioning post 2311 and the sealing plate 220 can provide a contraction space for the elastic body 2312 to reduce the risks such as contraction failure of the elastic body 2312.

[0108] In some embodiments, please continue to refer to Figure 4 , the floating mechanism 230 includes a plurality of second fixing rods 232, and the plurality of second fixing rods 232 extend along the first direction X-X and are sequentially arranged at intervals along the second direction Y-Y. Among them, a plurality of elastic components 231 are provided between each second fixing rod 232 and the sealing plate 220, and the plurality of elastic components 231 are sequentially arranged at intervals along the first direction X-X. The second direction Y-Y is parallel to the arrangement direction of the top and bottom of the box body 100 and perpendicular to the first direction X-X.

[0109] The number of the second fixing rods 232 can be two, three, five, seven, eight, etc., but is not limited thereto. The number of the elastic components 231 between each second fixing rod 232 and the sealing plate 220 can be two, four, five, six, eight, etc., but is not limited thereto. The specific number of the second fixing rods 232 and the specific number of the elastic components 231 can be selected according to the size of the door body 200.

[0110] By providing a plurality of second fixing rods 232 extending along the first direction X-X and arranged at intervals along the second direction Y-Y, and arranging a plurality of elastic components 231 between each second fixing rod 232 and the sealing plate 220, the plurality of elastic components 231 are dispersedly arranged at a plurality of positions between the sealing plate 220 and the door body 210. On the one hand, the plurality of elastic components 231 can automatically adjust the compression force according to the force condition, which can further improve the sealing effect of the sealing plate 220 on the baking cavity 100a. On the other hand, when a certain elastic component 231 is fatigued or damaged, the remaining elastic components 231 can also maintain the pressing force towards the box body 100 for the sealing door, enabling the door body 200 to have a fault tolerance ability and reducing the risk of air leakage in the baking cavity 100a caused by the sealing door being unable to float towards the box body 100 during the operation of the baking device 1000. On the other hand, the plurality of elastic components 231 can jointly share the thrust of the box body 100 towards the door body 200, relieve the fatigue aging speed of the elastic components 231, and contribute to extending the service life of the door body 200.

[0111] In some embodiments, please continue to refer to Figure 4 and Figure 6 , the door body 200 further includes a limiting component 260, the limiting component 260 is arranged between the door body 210 and the sealing plate 220, and at least a part of the limiting component 260 extends to the side of the sealing plate 220 facing away from the door body 210.

[0112] Among them, the limiting component 260 can be integrally formed on the door body 210; or the limiting component 260 can also be arranged on the door body 210 by a fixed connection method, where the fixed connection method can be welding, riveting, bolt connection, snap connection, etc., but is not limited thereto.

[0113] By extending at least a part of the limiting component 260 to the side of the sealing plate 220 facing away from the door body 210, the limiting component 260 can limit the floating range of the sealing plate 220 when the sealing plate 220 floats towards the box body 100, and reduce the risks of the sealing plate 220 tilting or being misaligned relative to the edge of the opening 100b due to excessive floating displacement towards the box body 100, thereby reducing the possibility of sealing failure of the sealing plate 220.

[0114] In some embodiments, the door body 200 includes two limiting components 260. One of the two limiting components 260 is disposed on one side of the door main body 210 close to the top of the cabinet 100, and the other is disposed on one side of the door main body 210 close to the bottom of the cabinet 100, so as to limit the floating displacement of the sealing plate 220 toward the cabinet 100 on both sides along the arrangement direction of the top and bottom of the cabinet 100, which can effectively improve the overall floating uniformity of the sealing plate 220, thereby improving the sealing effect of the sealing plate 220 on the baking cavity 100a.

[0115] In some embodiments, an avoidance groove 220a is formed on the side of the sealing plate 220 facing away from the door main body 210. The limiting component 260 includes a fixing portion 261 and a limiting main body 262. The fixing portion 261 is disposed on the door main body 210. The limiting main body 262 is disposed on the side of the fixing portion 261 close to the sealing plate 220 and at least partially extends into the avoidance groove 220a. When the door body 200 is in the open state, there is a gap between the limiting main body 262 and the bottom wall of the avoidance groove 220a.

[0116] When the door body 200 is in the closed state, the avoidance groove 220a is located on the side of the sealing plate 220 close to the cabinet 100. The bottom wall of the avoidance groove 220a is the inner wall of the avoidance groove 220a opposite to the cabinet 100.

[0117] By configuring the limiting component 260 to include a fixing portion 261 and a limiting main body 262, setting the fixing portion 261 on the door main body 210, and setting the limiting main body 262 on the fixing portion 261, the structural strength of the limiting main body 262 can be improved, and the risk of deformation or disconnection of the limiting main body 262 under the impact of the bottom wall of the avoidance groove 220a can be reduced.

[0118] By providing the avoidance groove 220a on the side of the sealing plate 220 facing away from the door main body 210, extending the limiting main body 262 of the limiting component 260 into the avoidance groove 220a, and having a gap between the limiting main body 262 and the bottom wall of the avoidance groove 220a when the door body 200 is in the open state, the gap between the limiting main body 262 and the avoidance groove 220a can provide a floating space for the sealing plate 220 toward the cabinet 100 during the closing process of the door body 200, so that the sealing plate 220 can float within the floating space defined by the limiting component 260.
