Description

Technical Field

[0001] This invention relates to the field of cooking appliance technology, and more specifically, to a control box device and a cooking appliance. Background Technology

[0002] In related technologies, microwave ovens can be opened by pulling the door after cooking. However, these microwave ovens lack child lock safety devices, posing a safety hazard as children could potentially be injured if they open a working microwave. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, a first aspect of the present invention provides a control box device.

[0005] A second aspect of the invention provides a cooking utensil.

[0006] In view of the above, a first aspect of the present invention provides a control box device for a cooking appliance, the cooking appliance including a door body, the door body including a door hook, the control box device including: a box body; a button movably connected to the box body, the button moving relative to the box body to move the door hook from a closed position to an open position; an unlocking member movably connected to the box body, the unlocking member being able to move from a first area to a second area when triggered; a locking member movably connected to the button, the locking member being able to switch between a third area and a fourth area when triggered; when the unlocking member is in the first area and the locking member is in the third area, the locking member is connected to the unlocking member to restrict the movement of the button; when the unlocking member is in the second area or the locking member is in the fourth area, the locking member is separated from the unlocking member to release the restriction on the movement of the button.

[0007] The present invention provides a control box device comprising a box body, buttons, an unlocking component, and a locking component.

[0008] The unlocking component is rotatably connected to the housing, and can move from the first area to the second area under the action of external force. The locking component is movably connected to the button, and can move from the third area to the fourth area under the action of external force, and vice versa.

[0009] When the unlocking component is in the first zone and the locking component is in the third zone, the locking component and the unlocking component are connected. The unlocking component and the locking component cooperate to restrict the movement of the button. At this time, the door hook cannot be moved from the closed position to the open position by pressing the button to open the door.

[0010] When an external force is applied to the unlocking component, causing it to move to the second region while the locking component is in the third region, the locking and unlocking components separate, releasing the restriction on the button's movement. When an external force is applied to both the unlocking and locking components, causing the unlocking component to be in the second region and the locking component to be in the fourth region, the locking and unlocking components separate, releasing the restriction on the button's movement. When the unlocking component is in the first region and an external force is applied to the locking component, causing it to be in the fourth region, the locking and unlocking components separate, releasing the restriction on the button's movement. In all three scenarios described above, pressing the button allows it to move relative to the housing, driving the door hook from the closed position to the open position, thus opening the door.

[0011] Specifically, opening the door requires two steps. First, pressing the unlocking mechanism moves it relative to the housing, rotating it from the first area to the second area. At this point, the unlocking mechanism separates from the locking mechanism, releasing the restriction on the button's movement. Second, pressing the button moves it relative to the housing, causing the door hook to move from the closed position to the open position. When the unlocking mechanism is in the first area and the locking mechanism is in the third area, the button's movement is restricted, preventing the door from being opened by pressing it. Even pulling the door will not open it; that is, the door will not unlock under external force, thus fundamentally solving the problem of children accidentally unlocking the door. This ensures the safety and reliability of cooking appliances, including the control box device.

[0012] Specifically, after the door is locked, the unlocking mechanism is in the first zone, and the locking mechanism is in the third zone. The unlocking and locking mechanisms are connected to restrict button movement. The door hook engages with the positioning component of the appliance body, preventing the door from being opened. At this time, even if a child pulls on the door, they cannot unlock it. In other words, the button and unlocking mechanism work together to achieve the function of a child lock; when the door is locked and the unlocking mechanism is in the first zone and the locking mechanism is in the third zone, the door cannot be opened.

[0013] Specifically, when an external force is applied to the locking member, causing it to move to the fourth region, the locking member separates from the unlocking member, thereby releasing the restriction on the movement of the button.

[0014] In other words, when the user does not need to use the child lock function, triggering the locking mechanism moves it to the fourth zone, where the locking and unlocking mechanisms remain separated, rendering the unlocking mechanism ineffective. Simply pressing a button moves the door hook from the closed position to the open position to open the door. This feature caters to diverse user needs, enhancing the product's usability and functionality.

[0015] As is understandable, the unlocking component is movably connected to the housing, and the unlocking component and housing form a single unit. The housing serves as the mounting carrier for the unlocking component, and it restricts the movement trajectory of the unlocking component. Similarly, the locking component is movably connected to the button, and the locking component and button form a single unit. The button serves as the mounting carrier for the locking component, and it restricts the movement trajectory of the locking component. When the unlocking component and locking component are connected, the locking component and button as a whole cannot move relative to the housing; that is, the button cannot be triggered to move relative to the housing.

[0016] The control box device according to the present invention may also have the following additional technical features:

[0017] In the above technical solution, the locking element is further connected to the button in a rotating manner.

[0018] In this technical solution, the cooperation structure between the locking element and the button is further defined. Specifically, the locking element and the button are rotatably connected. When an external force is applied to the locking element, the locking element can rotate relative to the button. For example, when the door is opened, the locking element is in the third region. Along the first direction, the locking element rotates relative to the button to move to the fourth region. Or, when the door is opened, the locking element is in the third region. Along the second direction, the locking element rotates relative to the button to move to the fourth region. The first direction is opposite to the second direction.

[0019] Specifically, the fourth region is located on one side of the third region.

[0020] Alternatively, the fourth region may be located on either side of the third region. That is, the third region may be located between the four fourth regions on either side.

[0021] In any of the above technical solutions, the locking member further includes a locking protrusion, the button includes a first clearance opening, the locking protrusion can extend the button through the first clearance opening, and the first clearance opening can limit the rotation angle of the locking member; the unlocking member includes a locking channel; when the unlocking member is in the first region and the locking member is in the third region, the locking protrusion can extend into the locking channel; when the unlocking member is in the second region or the locking member is in the fourth region, the locking protrusion separates from the locking channel.

[0022] In this technical solution, the locking component includes a locking protrusion, and the unlocking component includes a locking channel. When the unlocking component is in the first region and the locking component is in the third region, the locking protrusion can extend into the locking channel, satisfying the requirement for connection between the locking component and the unlocking component. When the unlocking component is in the second region, the locking protrusion separates from the locking channel, satisfying the requirement for separation between the locking component and the unlocking component. When the locking component is in the fourth region, the locking protrusion separates from the locking channel, satisfying the requirement for separation between the locking component and the unlocking component.

[0023] In other words, by adjusting the positional relationship between the locking and unlocking components, the locking protrusion can be connected to or separated from the locking channel, thereby restricting the movement of the button or releasing the restriction on the movement of the button.

[0024] In any of the above technical solutions, the button further includes a mounting channel and a protrusion, the protrusion being disposed in the mounting channel; the locking member includes a first latch, the first latch extending into the mounting channel and engaging with the protrusion.

[0025] In this technical solution, by rationally setting the mating structure of the button and the locking component, the button includes a mounting channel and a protrusion, with the protrusion located in the mounting channel. The locking component includes a first snap-fit. When the locking component and the button are assembled, the first snap-fit ​​extends into the mounting channel and engages with the protrusion. In other words, the first snap-fit ​​and the protrusion cooperate to limit the locking component along the length of the mounting channel, ensuring that the locking component will not shift along the length of the mounting channel when it rotates relative to the button, thus guaranteeing the mating dimensions of the button and the locking component.

[0026] Specifically, the locking element can rotate relative to the mounting channel.

[0027] Specifically, the locking element and the button are detachably connected. Specifically, the first latch and the protrusion are detachably connected. That is, the first latch and the protrusion can be separated or assembled together according to actual usage needs. This design simplifies the assembly structure of the locking element and the button, making the disassembly and assembly process simple and reducing the difficulty of disassembling and assembling the locking element and the button.

[0028] In any of the above technical solutions, the first buckle further includes: a connecting arm, the connecting arm including a positioning section and a slot, the positioning section being located on the periphery of the slot; and a buckle head connected to one side of the connecting arm, the buckle head being engaged with one side of the protrusion; wherein the protrusion can be engaged within the slot.

[0029] In this technical solution, the first buckle includes a connecting arm and a buckle head. The buckle head is connected to one side of the connecting arm. The connecting arm includes a positioning section and a slot. The positioning section is located on the periphery of the slot.

[0030] When the unlocking component is in the first area and the locking component is in the third area, the buckle is connected to one side of the connecting arm, and the protrusion can be engaged in the slot. The protrusion, the slot and the buckle cooperate to achieve the purpose of limiting the locking component in multiple directions and multiple angles, so that the locking component and the button are assembled into a whole and the position is limited.

[0031] When the door is opened, the locking mechanism is rotated, causing the slot to rotate as well, and the protrusion to separate from the slot. The protrusion then gradually moves away from the slot and abuts against the positioning section. This abutment locks the locking mechanism in place, preventing it from rotating and naturally resetting. This effectively confines the locking mechanism to the fourth zone, preventing it from resetting to the third zone under its own weight.

[0032] In any of the above technical solutions, the locking element further includes a marking portion located on one side of the button.

[0033] In this technical solution, by rationally designing the structure of the locking component, the locking component includes an indicator section located on one side of the button. The indicator section is exposed, meaning it is not obstructed by the button, and it indicates the rotation direction of the locking component. This facilitates user identification and operation, and offers high operability.

[0034] Specifically, the signage section includes text or symbols. For example, the signage section may include arrows indicating direction. Or, the signage section may include the words "turn left" and / or "turn right".

[0035] It is understandable that the first part of the locking member is located inside the button, and the part of the locking member inside the button is rotatably connected to the button. The second part of the locking member is located outside the button, and the part of the locking member outside the button is provided with a marking part.

[0036] In any of the above technical solutions, the control box device further includes: a reset member disposed in the box body, the reset member being able to drive the unlocking member to reset from the second region to the first region.

[0037] In this technical solution, a reset component is located within the housing, and this component drives the unlocking component to reset from the second area to the first area. When the door is closed, the external force acting on the unlocking component is removed, and the reset component drives the unlocking component to reset from the second area to the first area. In other words, the reset component provides the power support for the unlocking component to move from the second area to the first area, and provides structural protection for the unlocking component to move between the first and second areas, thus achieving the goal of resetting the unlocking component so that it cooperates with the locking component to lock the door. This design enables the cooking appliance to have an automatic locking function, improving the product's usability and market competitiveness.

[0038] In any of the above technical solutions, the reset component is further defined as an elastic reset component.

[0039] In this technical solution, the structure of the reset element is defined; specifically, the reset element is an elastic reset element. When the user presses the unlocking element, the unlocking element rotates relative to the housing. The movement of the unlocking element compresses the elastic reset element, causing it to deform. After the external force acting on the unlocking element is removed, the elastic reset element resets, thereby driving the unlocking element to reset from the second region to the first region.

[0040] In any of the above technical solutions, the unlocking component includes a positioning part with a locking channel, and the resetting component includes a mating section connected to one side of the positioning part; wherein, along the height direction of the box body, at least a portion of the positioning part is located above the mating section.

[0041] In this technical solution, the unlocking component includes a positioning part, and the resetting component includes a mating section. By reasonably setting the mating structure of the unlocking component and the resetting component, the mating section is connected to the positioning part, and at least a portion of the positioning part is located above the mating section along the height direction of the box.

[0042] Specifically, when the door is opened, the unlocking component is pressed, causing the unlocking component to rotate relative to the box. When the unlocking component moves, the positioning part can squeeze the mating section, causing the mating section to deform toward the bottom of the box until the unlocking component rotates from the first area to the second area.

[0043] Specifically, removing the external force acting on the unlocking component allows the resetting section to drive the positioning part to move, thus fulfilling the requirement for the unlocking component to reset from the second region to the first region. In other words, the resetting section provides the power support for the unlocking component to move from the second region to the first region, and provides structural protection for the unlocking component to move between the first and second regions, thereby achieving the purpose of locking the door.

[0044] Because the mating section is connected to the positioning part, it provides effective and reliable structural support for the unlocking part to press the reset part to deform the reset part and for the reset part to drive the unlocking part to reset.

[0045] In addition, the positioning part is equipped with a locking channel, that is, the positioning part is the carrier of the locking channel. This configuration can ensure that the locking channel and the locking protrusion of the locking member effectively cooperate.

[0046] In any of the above technical solutions, the mating section is further provided with a second clearance opening, and the locking channel is connected to the second clearance opening.

[0047] In this technical solution, the mating section is provided with a second clearance opening, and the locking channel is connected to the second clearance opening. That is, a part of the mating section is provided corresponding to the locking channel, and the part of the mating section corresponding to the locking channel is provided with a second clearance opening, which is corresponding to and connected to the locking channel.

[0048] When the unlocking component is in the first region and the locking component is in the third region, the locking protrusion can extend into the locking channel and the second clearance opening. This satisfies the requirement for connection between the locking and unlocking components. When the unlocking component is in the second region, the locking protrusion separates from the locking channel and the second clearance opening, satisfying the requirement for separation between the locking and unlocking components. When the locking component is in the fourth region, the locking protrusion separates from the locking channel and the second clearance opening, satisfying the requirement for separation between the locking and unlocking components.

[0049] In other words, by adjusting the positional relationship between the locking and unlocking components, the locking protrusion can be connected to or separated from the locking channel and the second clearance port, thereby restricting the movement of the button or releasing the restriction on the movement of the button.

[0050] In any of the above technical solutions, a limiting surface is further provided on the side of the positioning part away from the mating section, and the limiting surface is located on the periphery of the locking channel.

[0051] In this technical solution, by rationally designing the structure of the positioning part, a limiting surface is provided on the side of the positioning part away from the mating section. Furthermore, the mating structure of the limiting surface and the locking channel is configured such that the limiting surface is located on the periphery of the locking channel.

[0052] Specifically, when the user does not need to use the child lock function, by rotating the locking component, the locking protrusion of the locking component separates from the locking channel and the second clearance port. Then, the locking protrusion abuts against the limiting surface, and the limiting surface acts as an obstacle to the locking protrusion, so that the unlocking component will not reset, thus ensuring that the locking component is locked in the fourth area. The locking component and the unlocking component are always in a separated state. At this time, the unlocking component is in a disabled state.

[0053] Specifically, when opening the door, the first step is to press the unlocking mechanism, causing it to move relative to the housing and rotate from the first area to the second area. At this point, the unlocking mechanism separates from the locking mechanism, releasing the restriction on the button's movement. The second step is to press the button, causing it to move relative to the housing. The locking protrusion moves away from the locking channel and the second clearance opening along the opening direction and abuts against the limiting surface in the opening direction. The limiting component obstructs the locking protrusion, preventing the unlocking mechanism from resetting.

[0054] In any of the above technical solutions, the button is further provided with a notch, which encloses an avoidance area; when the unlocking member is in the first area, the positioning part is located in the avoidance area; when the unlocking member is in the second area, the positioning part is separated from the avoidance area.

[0055] In this technical solution, by reasonably setting the structure of the button, the button is provided with a notch, the notch surrounds an avoidance area, and when the unlocking member is in the first area, the positioning part is located in the avoidance area, and when the unlocking member is in the second area, the positioning part is separated from the avoidance area.

[0056] In other words, the avoidance area serves as a positioning part to accommodate the unlocking component, thereby reducing the overall size of the unlocking component and the button when the unlocking component is in the first area, thus reducing the space occupied by the box and facilitating the reasonable layout of other components of the control box device.

[0057] In any of the above technical solutions, a portion of the unlocking component extends out of the button through the avoidance area, and the portion of the unlocking component outside the button forms a toggle protrusion.

[0058] In this technical solution, by reasonably designing the structure of the unlocking component, a toggle protrusion is formed on the part of the unlocking component located outside the box. That is, the toggle protrusion is located on the outside of the box and can be exposed, so that the user can rotate the toggle protrusion to achieve the purpose of rotating the unlocking component and the box.

[0059] This design makes it easy for users to hold the unlocking mechanism, ensuring ease of operation when the unlocking mechanism rotates relative to the box.

[0060] In any of the above technical solutions, the reset component further includes a support section, which is bent from the mating section toward the bottom of the housing so that the mating section is connected to the positioning part.

[0061] In this technical solution, by rationally designing the structure of the reset component, the reset component also includes a support section, which is connected to the mating section. The support section is bent from the mating section towards the bottom of the housing. The support section supports the mating section to ensure the mating dimensions of the mating section and the positioning part, thus enabling the mating section to connect with the positioning part.

[0062] Furthermore, the bent arrangement of the mating section enhances the structural strength of the reset component, thereby ensuring the effectiveness and feasibility of the support section supporting the mating section. This prevents the mating section from tilting and provides effective and reliable structural support for the connection between the mating section and the positioning part. It also meets the requirement that the reset component can drive the unlocking component to reset from the second area to the first area.

[0063] In any of the above technical solutions, the box body is further provided with a mounting groove, and the button, reset component and unlocking component are all provided in the mounting groove, with the unlocking component located between the button and the reset component.

[0064] In this technical solution, by rationally designing the mating structure of the housing, button, and reset component, the housing is provided with a mounting slot, and the button, reset component, and unlocking component are all located in the mounting slot. The button and reset component together enclose a mounting area, which serves to accommodate the unlocking component. Specifically, the unlocking component is located between the button and the reset component.

[0065] In other words, the button and reset component serve to install and secure the unlocking component, ensuring the proper fit of the button, reset component, and unlocking component.

[0066] This design, while ensuring the functionality of the buttons, reset components, and unlocking components, increases the mating dimensions between the unlocking components and the buttons and reset components, thus ensuring the stability and reliability of the product assembly.

[0067] In any of the above technical solutions, the box body is further provided with a first opening and a second opening, both of which are connected to the mounting groove; the button also includes a drive rod and a second latch, the second latch extends out of the box body through the first opening and abuts against the outer surface of the box body, the drive rod extends out of the box body through the second opening, and the drive rod is used to drive the door hook to move from the closed position to the open position.

[0068] In this technical solution, the housing also has a first opening and a second opening. The first opening connects to the mounting slot, and the second opening also connects to the mounting slot. The button also includes a drive rod and a second latch. When the button is assembled with the mounting slot, the second latch extends out of the housing through the first opening and abuts against the outer surface of the housing. In other words, the second latch serves to limit the assembly dimensions of the button and the housing, preventing the button from detaching from the mounting slot and providing reliable structural support for effectively triggering the button.

[0069] In addition, the drive rod extends out of the box through the second opening, which means that it can meet the needs of the drive rod to drive the door hook from the closing area to the opening area.

[0070] In any of the above technical solutions, the control box device further includes: an elastic element connecting the drive rod and the box body, the elastic element being used to reset the button.

[0071] In this technical solution, the control box device also includes an elastic element that enables the button to reset. That is, the elastic element provides the power support for button reset.

[0072] When an external force is applied to the button, the button moves toward the inside of the housing, and the elastic element is compressed accordingly.

[0073] When the external force applied to the button is removed, the button returns to its original position under the action of the elastic element. This design provides effective and reliable structural support for the movement of the button relative to the housing.

[0074] In any of the above technical solutions, the control box device further includes: a flap, which is rotatably connected to one side of the box body, and a drive rod drives the door hook to move through the flap.

[0075] In this technical solution, the control box device also includes a flap, which is located on the outside of the box body and is rotatably connected to the box body. An external force is applied to the button, and the button's drive rod moves relative to the box body. The movement of the drive rod drives the flap to rotate relative to the box body. The rotation of the flap can drive the lever movement of the appliance body (specifically, the cooking appliance includes the appliance body, the door is openably connected to the appliance body, and the appliance body includes the control box device). The lever movement pushes open the door hook, thereby opening the door.

[0076] When the external force applied to the button is removed, the drive rod resets, the drive rod separates from the flap, the flap resets, and the lever also resets.

[0077] In any of the above technical solutions, the reset component is further detachably connected to the housing.

[0078] In this technical solution, the reset component and the box body are detachably connected. That is, the detachment and assembly of the reset component and the box body and the installation area of ​​the reset component relative to the box body can be determined according to the actual situation. This makes it suitable for the use needs of different models of control box devices, and the product has strong adaptability, which improves the performance of the product.

[0079] In this technical solution, the unlocking component and the box body are detachably connected. That is, the detachment and assembly of the unlocking component and the box body and the installation area of ​​the unlocking component relative to the box body can be determined according to the actual situation. This makes it suitable for the use requirements of different types of control devices, and the product has strong adaptability, which improves the performance of the product.

[0080] In any of the above technical solutions, a positioning block is further provided inside the box. The positioning block is located on one side of the unlocking component. The positioning block includes a first wall surface and a second wall surface. The first wall surface faces the bottom of the box, and the second wall surface is located away from the unlocking component. The reset component includes a connecting section. The connecting section is located inside the box. The connecting section bypasses the first wall surface and is connected to the second wall surface by a fastener.

[0081] In this technical solution, a positioning block is provided inside the box, and the reset component includes a connecting section located inside the box. The positioning block includes a first wall surface and a second wall surface. The first wall surface faces the bottom of the box, and the second wall surface is located away from the unlocking component.

[0082] By rationally designing the mating structure between the housing and the reset component, the connecting section of the reset component extends into the housing, bypasses the first wall, and is connected to the second wall via fasteners. In other words, the reset component and the housing can be detachably connected via fasteners.

[0083] Since one part of the connecting section is set to correspond to the first wall and the other part of the connecting section is set to correspond to the second wall, this setting increases the mating area between the reset component and the positioning block of the box, enriches the mating angle between the reset component and the positioning block, and helps to improve the stability and reliability of the assembly of the reset component and the box.

[0084] Meanwhile, since the connecting segment bypasses the first wall and connects to the second wall, that is, the connecting segment is arranged in a bent manner. This arrangement can improve the structural strength of the reset component, thereby ensuring the matching dimensions of the reset component, the unlocking component, and the housing, and providing effective and reliable structural support for the reset component to effectively drive the unlocking component to reset from the second region to the first region.

[0085] A second aspect of the present invention provides a cooking appliance, comprising: an appliance body, the appliance body including a control box device as described in any of the technical solutions in the first aspect; and a door, which is openable and closable connected to the appliance body.

[0086] The cooking appliance provided by the present invention includes a control device as described in any of the technical solutions in the first aspect, and therefore has all the beneficial effects of the control device.

Detailed Implementation

[0111] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0112] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0113] The following reference Figures 1 to 20 A control device 100 and a cooking appliance are described according to some embodiments of the present invention.

[0114] Example 1:

[0115] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, an embodiment of the first aspect of the present invention provides a control box device 100 for a cooking appliance, the cooking appliance including a door body, the door body including a door hook 400, and the control box device 100 including a box body 110, a button 130, an unlocking member 150 and a locking member 160.

[0116] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0117] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0118] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0119] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0120] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0121] In detail, the control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0122] The unlocking component 150 is rotatably connected to the housing 110, and can move from the first area to the second area under the action of external force. The locking component 160 is movably connected to the button 130, and can move from the third area to the fourth area under the action of external force, and can also move from the fourth area to the third area under the action of external force.

[0123] When the unlocking member 150 is in the first area and the locking member 160 is in the third area, the locking member 160 and the unlocking member 150 are connected. The unlocking member 150 and the locking member 160 cooperate to restrict the movement of the button 130. At this time, the door hook 400 cannot be moved from the closed position to the open position by pressing the button 130 to open the door.

[0124] When an external force is applied to the unlocking member 150, causing it to move to the second region and the locking member 160 to be in the third region, the locking member 160 separates from the unlocking member 150, releasing the restriction on the movement of the button 130. When an external force is applied to both the unlocking member 150 and the locking member 160, causing the unlocking member 150 to be in the second region and the locking member 160 to be in the fourth region, the locking member 160 separates from the unlocking member 150, releasing the restriction on the movement of the button 130. When the unlocking member 150 is in the first region and an external force is applied to the locking member 160, causing it to be in the fourth region, the locking member 160 separates from the unlocking member 150, releasing the restriction on the movement of the button 130. In all three cases described above, pressing the button 130 allows it to move relative to the housing 110, driving the door hook 400 from the closed position to the open position, thus opening the door.

[0125] Specifically, opening the door requires two steps. First, pressing the unlocking element 150 moves it relative to the housing 110, rotating it from the first area to the second area. At this point, the unlocking element 150 separates from the locking element 160, releasing the restriction on the movement of the button 130. Second, pressing the button 130 moves it relative to the housing 110, causing the door hook 400 to move from the closed position to the open position. When the unlocking element 150 is in the first area and the locking element 160 is in the third area, the button 130 is restricted from movement, preventing the door from being opened by pressing the button 130. Even pulling the door will not open it; that is, the door will not unlock under external force, thus fundamentally solving the problem of children accidentally unlocking the door. This ensures the safety and reliability of cooking appliances, including the control box device 100.

[0126] Specifically, after the door is locked, the unlocking component 150 is in the first area, and the locking component 160 is in the third area. The unlocking component 150 and the locking component 160 are connected to restrict the movement of the button 130. The door hook 400 of the door is engaged with the positioning component of the appliance body, making it impossible to open the door. At this time, even if a child pulls on the door, it cannot be unlocked. In other words, the button 130 and the unlocking component 150 work together to achieve the function of a child lock. When the door is locked and the unlocking component 150 is in the first area and the locking component 160 is in the third area, the door cannot be opened.

[0127] Specifically, when an external force is applied to the locking member 160, causing the locking member 160 to move to the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0128] In other words, when the user does not need to use the child lock function, triggering the locking element 160 causes it to move to the fourth zone. The locking element 160 and the unlocking element 150 remain separated, and the unlocking element 150 is inactive at this time. Simply pressing button 130 moves the door hook 400 from the closed position to the open position to open the door. This feature meets different user needs and enhances the product's usability and functionality.

[0129] It is understandable that the unlocking component 150 is movably connected to the housing 110, and the unlocking component 150 and the housing 110 form a whole, with the housing 110 serving as the mounting carrier for the unlocking component 150. The housing 110 can restrict the movement trajectory of the unlocking component 150. Similarly, the locking component 160 is movably connected to the button 130, and the locking component 160 and the button 130 form a whole, with the button 130 serving as the mounting carrier for the locking component 160. The button 130 can restrict the movement trajectory of the locking component 160. When the unlocking component 150 and the locking component 160 are connected, the locking component 160 and the button 130 as a whole cannot move relative to the housing 110; that is, the button 130 cannot be triggered to move relative to the housing 110.

[0130] Specifically, Figure 7 The arrow in the image indicates the direction of movement of the unlocking component 150.

[0131] Specifically, Figure 9 The arrows in the diagram indicate the direction of movement of button 130, as well as the direction of movement of lever 300 and hook 400.

[0132] Example 2:

[0133] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, based on Embodiment 1, Embodiment 2 provides a control box device 100 for a cooking appliance. The cooking appliance includes a door body, which includes a door hook 400. The control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0134] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0135] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0136] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0137] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0138] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0139] Furthermore, the locking element 160 is rotatably connected to the button 130.

[0140] In detail, the mating structure of the locking member 160 and the button 130 is further defined. Specifically, the locking member 160 is rotatably connected to the button 130. When an external force is applied to the locking member 160, the locking member 160 can rotate relative to the button 130. Figure 11 As shown, when the door is opened, the locking member 160 is in the third region. Along the first direction, the locking member 160 rotates relative to the button 130 to move to the fourth region. (As shown) Figure 14 As shown, when the door is opened, the locking member 160 is in the third region. Along the second direction, the locking member 160 rotates relative to the button 130 to move to the fourth region. The first direction is opposite to the second direction. Figure 11 and Figure 14 The arrow in the diagram indicates the direction of rotation of the locking element 160.

[0141] Specifically, the fourth region is located on one side of the third region.

[0142] Alternatively, the fourth region may be located on either side of the third region. That is, the third region may be located between the four fourth regions on either side.

[0143] Example 3:

[0144] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, based on Embodiment 2, Embodiment 3 provides a control box device 100 for cooking appliances. The cooking appliances include a door body, the door body includes a door hook 400, and the control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0145] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0146] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0147] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0148] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0149] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0150] The locking element 160 is rotatably connected to the button 130.

[0151] Furthermore, such as Figure 5 , Figure 6 , Figure 17 , Figure 18 , Figure 19 and Figure 20 As shown, the locking member 160 includes a locking protrusion 162, and the button 130 includes a first clearance opening 132.

[0152] The locking protrusion 162 can extend the button 130 through the first clearance opening 132, and the first clearance opening 132 can limit the rotation angle of the locking member 160.

[0153] The unlocking component 150 includes a locking channel 152.

[0154] When the unlocking member 150 is in the first region and the locking member 160 is in the third region, the locking protrusion 162 can extend into the locking channel 152.

[0155] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking protrusion 162 separates from the locking channel 152.

[0156] In detail, the locking member 160 includes a locking protrusion 162, and the unlocking member 150 includes a locking channel 152. When the unlocking member 150 is in the first region and the locking member 160 is in the third region, the locking protrusion 162 can extend into the locking channel 152, satisfying the usage requirement of connecting the locking member 160 and the unlocking member 150. When the unlocking member 150 is in the second region, the locking protrusion 162 is separated from the locking channel 152, satisfying the usage requirement of separating the locking member 160 and the unlocking member 150. When the locking member 160 is in the fourth region, the locking protrusion 162 is separated from the locking channel 152, satisfying the usage requirement of separating the locking member 160 and the unlocking member 150.

[0157] In other words, by adjusting the positional relationship between the locking member 160 and the unlocking member 150, the locking protrusion 162 is connected to or separated from the locking channel 152, so as to restrict the movement of the button 130 or release the restriction on the movement of the button 130.

[0158] Example 4:

[0159] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, based on any of the above embodiments, Embodiment 4 provides a control box device 100 for a cooking appliance. The cooking appliance includes a door body, the door body includes a door hook 400, and the control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0160] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0161] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0162] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0163] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0164] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0165] Furthermore, such as Figure 17 , Figure 18 and Figure 19 As shown, button 130 includes mounting channel 134 and bump 136, with bump 136 located in mounting channel 134.

[0166] The locking element 160 includes a first latch 164 that extends into the mounting channel 134 and engages with the protrusion 136.

[0167] In detail, by reasonably setting the mating structure of the button 130 and the locking member 160, the button 130 includes a mounting channel 134 and a protrusion 136, with the protrusion 136 located in the mounting channel 134. The locking member 160 includes a first latch 164. When the locking member 160 and the button 130 are assembled, the first latch 164 extends into the mounting channel 134 and engages with the protrusion 136. That is, the first latch 164 and the protrusion 136 cooperate to limit the locking member 160 along the length direction of the mounting channel 134, so that when the locking member 160 rotates relative to the button 130, the locking member 160 will not shift along the length direction of the mounting channel 134, thus ensuring the mating dimensions of the button 130 and the locking member 160.

[0168] Specifically, the locking element 160 is rotatable relative to the mounting channel 134.

[0169] Specifically, the locking element 160 and the button 130 are detachably connected. Specifically, the first latch 164 and the protrusion 136 are detachably connected. That is, the first latch 164 and the protrusion 136 can be separated or assembled together according to actual usage needs. This design simplifies the assembly structure of the locking element 160 and the button 130, simplifies the disassembly and assembly process, and reduces the difficulty of disassembling and assembling the locking element 160 and the button 130.

[0170] Example 5:

[0171] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, based on embodiment 4, embodiment 5 provides a control box device 100 for cooking appliances. The cooking appliances include a door body, the door body includes a door hook 400, and the control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0172] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0173] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0174] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0175] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0176] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0177] The button 130 includes a mounting channel 134 and a bump 136, with the bump 136 located in the mounting channel 134.

[0178] The locking element 160 includes a first latch 164 that extends into the mounting channel 134 and engages with the protrusion 136.

[0179] Furthermore, such as Figure 17 As shown, the first buckle 164 includes a connecting arm 166 and a buckle head 172.

[0180] The connecting arm 166 includes a positioning section 168 and a slot 170, with the positioning section 168 located around the slot 170.

[0181] The buckle 172 is connected to one side of the connecting arm 166 and is snapped onto one side of the protrusion 136.

[0182] The protrusion 136 can be engaged in the slot 170.

[0183] In detail, the first buckle 164 includes a connecting arm 166 and a buckle head 172. The buckle head 172 is connected to one side of the connecting arm 166. The connecting arm 166 includes a positioning section 168 and a slot 170. The positioning section 168 is located on the periphery of the slot 170.

[0184] When the unlocking member 150 is in the first region and the locking member 160 is in the third region, the buckle 172 is connected to one side of the connecting arm 166, and the protrusion 136 can be engaged in the slot 170. The protrusion 136, the slot 170 and the buckle 172 cooperate to achieve the purpose of limiting the locking member 160 in multiple directions and multiple angles, so that the locking member 160 and the button 130 are assembled into a whole and the position is defined.

[0185] When the door is opened, the locking element 160 is rotated, and the slot 170 rotates accordingly, causing the protrusion 136 to separate from the slot 170. The protrusion 136 then gradually moves away from the slot 170 and abuts against the positioning section 168. The abutment between the protrusion 136 and the positioning section 168 locks the locking element 160, preventing it from rotating and naturally resetting. This effectively limits the locking element 160 to the fourth region, preventing it from resetting to the third region under its own weight.

[0186] Example 6:

[0187] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, based on any of the above embodiments, Embodiment 6 provides a control box device 100 for a cooking appliance. The cooking appliance includes a door body, the door body includes a door hook 400, and the control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0188] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0189] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0190] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0191] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0192] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0193] Furthermore, such as Figure 17 As shown, the locking member 160 includes a marking portion 174, which is located on one side of the button 130.

[0194] In detail, by reasonably setting the structure of the locking member 160, the locking member 160 includes an indicator portion 174, which is located on one side of the button 130 and is exposed, meaning that the indicator portion 174 is not obstructed by the button 130. The indicator portion 174 can indicate the rotation direction of the locking member 160. This facilitates user identification and operation, and provides high operability.

[0195] Specifically, the sign section 174 includes text or symbols. For example, the sign section 174 includes arrows indicating direction. Or, the sign section 174 includes the words "turn left" and / or "turn right".

[0196] It is understood that the first part of the locking member 160 is located inside the button 130, and the part of the locking member 160 inside the button 130 is rotatably connected to the button 130. The second part of the locking member 160 is located outside the button 130, and the part of the locking member 160 outside the button 130 is provided with a marking part 174.

[0197] Specifically, the locking protrusion 162 is located on one side of the first latch 164.

[0198] Specifically, the number of first latches 164 is one, or the number of first latches 164 is multiple. When the number of first latches 164 is multiple, the multiple first latches 164 are arranged at intervals along the rotation direction of the locking member 160. This arrangement can increase the mating area between the first latches 164 and the button 130, enrich the mating angle between the first latches 164 and the button 130, ensure the balance and consistency of the force on the locking member 160, improve the stability and reliability of the assembly of the first latches 164 and the button 130, avoid the locking member 160 from tilting, and provide reliable and stable structural support for the effective cooperation between the locking member 160 and the unlocking member 150.

[0199] Example 7:

[0200] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, based on any of the above embodiments, Embodiment 7 provides a control box device 100 for a cooking appliance. The cooking appliance includes a door body, the door body includes a door hook 400, and the control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0201] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0202] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0203] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0204] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0205] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0206] Furthermore, such as Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 12 , Figure 13 , Figure 15 , Figure 16 and Figure 20 As shown, the control box device 100 also includes a reset member 180, which is disposed in the box body 110. The reset member 180 can drive the unlocking member 150 to reset from the second region to the first region.

[0207] In detail, the reset member 180 is located on the housing 110, and the reset member 180 can drive the unlocking member 150 to reset from the second area to the first area. When the door is closed, the external force acting on the unlocking member 150 is removed, and the reset member 180 can drive the unlocking member 150 to reset from the second area to the first area. That is to say, the reset member 180 provides power support for the unlocking member 150 to move from the second area to the first area, and provides structural protection for the unlocking member 150 to move between the first area and the second area, so as to achieve the purpose of resetting the unlocking member 150, so that the unlocking member 150 and the locking member 160 cooperate to lock the door. This setting enables the cooking appliance to have an automatic locking function, improving the product's performance and market competitiveness.

[0208] Furthermore, the reset element 180 is an elastic reset element.

[0209] Specifically, the reset member 180 is a resilient reset member. When a user presses the unlocking member 150, the unlocking member 150 rotates relative to the housing 110. The movement of the unlocking member 150 compresses the resilient reset member, causing it to deform. After the external force applied to the unlocking member 150 is removed, the resilient reset member returns to its original position, thereby driving the unlocking member 150 to return to its original position from the second region to the first region.

[0210] Example 8:

[0211] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, based on Embodiment 7, Embodiment 8 provides a control box device 100 for a cooking appliance. The cooking appliance includes a door body, the door body includes a door hook 400, and the control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0212] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0213] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0214] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0215] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0216] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0217] The control box device 100 also includes a reset member 180, which is located in the box body 110. The reset member 180 can drive the unlocking member 150 to reset from the second area to the first area.

[0218] The reset component 180 is an elastic reset component.

[0219] Furthermore, such as Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 12 , Figure 13 , Figure 15 , Figure 16 and Figure 20 As shown, the unlocking component 150 includes a positioning part 154, which has a locking channel 152. The resetting component 180 includes a mating section 182, which is connected to one side of the positioning part 154.

[0220] In particular, along the height direction of the box body 110, at least a portion of the positioning part 154 is located above the mating section 182.

[0221] In detail, the unlocking component 150 includes a positioning part 154, and the resetting component 180 includes a mating section 182. By reasonably setting the mating structure of the unlocking component 150 and the resetting component 180, the mating section 182 is connected to the positioning part 154, and at least a portion of the positioning part 154 is located above the mating section 182 along the height direction of the housing 110.

[0222] Specifically, when the door is opened, the unlocking member 150 is pressed, causing the unlocking member 150 to rotate relative to the box body 110. When the unlocking member 150 moves, the positioning part 154 can press the mating section 182, causing the mating section 182 to deform toward the bottom of the box body 110 until the unlocking member 150 rotates from the first area to the second area.

[0223] Specifically, removing the external force acting on the unlocking member 150 allows the positioning part 154 to move, thus fulfilling the requirement for the unlocking member 150 to reset from the second region to the first region. In other words, the cooperating section 182 provides power support for the unlocking member 150 to move from the second region to the first region, and provides structural protection for the unlocking member 150 to move between the first and second regions, thereby achieving the purpose of locking the door.

[0224] Since the mating section 182 is connected to the positioning part 154, it provides effective and reliable structural support for the unlocking member 150 to press the reset member 180 to deform the reset member 180 and for the reset member 180 to drive the unlocking member 150 to reset.

[0225] In addition, the positioning part 154 is provided with a locking channel 152, that is, the positioning part 154 is the carrier of the locking channel 152. This arrangement can ensure that the locking channel 152 and the locking protrusion 162 of the locking member 160 are effectively engaged.

[0226] Example 9:

[0227] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, based on embodiment 8, embodiment 9 provides a control box device 100 for cooking appliances. The cooking appliances include a door body, the door body includes a door hook 400, and the control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0228] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0229] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0230] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0231] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0232] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0233] The control box device 100 also includes a reset member 180, which is located in the box body 110. The reset member 180 can drive the unlocking member 150 to reset from the second area to the first area.

[0234] The reset component 180 is an elastic reset component.

[0235] The unlocking component 150 includes a positioning part 154, which has a locking channel 152. The resetting component 180 includes a mating section 182, which is connected to one side of the positioning part 154.

[0236] In particular, along the height direction of the box body 110, at least a portion of the positioning part 154 is located above the mating section 182.

[0237] Furthermore, such as Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 12 , Figure 13 , Figure 15 , Figure 16 and Figure 20 As shown, the mating section 182 is provided with a second clearance opening 184, and the locking channel 152 is connected to the second clearance opening 184.

[0238] In detail, the mating section 182 is provided with a second clearance opening 184, and the locking channel 152 is connected to the second clearance opening 184. That is, a part of the mating section 182 is provided corresponding to the locking channel 152, and the part of the mating section 182 corresponding to the locking channel 152 is provided with the second clearance opening 184, and the second clearance opening 184 is corresponding to and connected to the locking channel 152.

[0239] When the unlocking member 150 is in the first region and the locking member 160 is in the third region, the locking protrusion 162 can extend into the locking channel 152 and the second clearance opening 184, satisfying the usage requirement of connecting the locking member 160 and the unlocking member 150. When the unlocking member 150 is in the second region, the locking protrusion 162 separates from the locking channel 152 and the second clearance opening 184, satisfying the usage requirement of separating the locking member 160 and the unlocking member 150. When the locking member 160 is in the fourth region, the locking protrusion 162 separates from the locking channel 152 and the second clearance opening 184, satisfying the usage requirement of separating the locking member 160 and the unlocking member 150.

[0240] In other words, by adjusting the positional relationship between the locking member 160 and the unlocking member 150, the locking protrusion 162 is connected to or separated from the locking channel 152 and the second clearance port 184, so as to restrict the movement of the button 130 or release the restriction on the movement of the button 130.

[0241] Furthermore, such as Figure 20 As shown, the positioning part 154 has a limiting surface 155 on the side opposite to the mating section 182, and the limiting surface 155 is located on the periphery of the locking channel 152.

[0242] Specifically, by reasonably setting the structure of the positioning part 154, a limiting surface 155 is provided on the side of the positioning part 154 that is away from the mating section 182. The mating structure of the limiting surface 155 and the locking channel 152 is such that the limiting surface 155 is located on the periphery of the locking channel 152.

[0243] Specifically, when the user does not need to use the child lock function, by rotating the locking member 160, the locking protrusion 162 of the locking member 160 separates from the locking channel 152 and the second clearance opening 184. Then, the locking protrusion 162 abuts against the limiting surface 155, and the limiting surface 155 obstructs the locking protrusion 162, so that the unlocking member 150 will not reset, thus ensuring that the locking member 160 is locked in the fourth area. The locking member 160 and the unlocking member 150 are always in a separated state. At this time, the unlocking member 150 is in a disabled state.

[0244] Specifically, when opening the door, the first step is to press the unlocking member 150, causing it to move relative to the housing 110 and rotate from the first area to the second area. At this time, the unlocking member 150 separates from the locking member 160, releasing the movement restriction on the button 130. The second step is to press the button 130, causing it to move relative to the housing 110. The locking protrusion 162 moves away from the locking channel 152 and the second clearance opening 184 along the door opening direction, and abuts against the limiting surface 155 in the door opening direction. The limiting member obstructs the locking protrusion 162, preventing the unlocking member 150 from resetting.

[0245] Example 10:

[0246] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, based on Embodiment 8, Embodiment 10 provides a control box device 100 for a cooking appliance. The cooking appliance includes a door body, the door body includes a door hook 400, and the control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0247] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0248] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0249] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0250] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0251] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0252] The control box device 100 also includes a reset member 180, which is located in the box body 110. The reset member 180 can drive the unlocking member 150 to reset from the second area to the first area.

[0253] The reset component 180 is an elastic reset component.

[0254] The unlocking component 150 includes a positioning part 154, which has a locking channel 152. The resetting component 180 includes a mating section 182, which is connected to one side of the positioning part 154.

[0255] In particular, along the height direction of the box body 110, at least a portion of the positioning part 154 is located above the mating section 182.

[0256] Furthermore, such as Figure 18 and Figure 19 As shown, button 130 has a notch 138, which encloses an avoidance area.

[0257] When the unlocking part 150 is in the first area, the positioning part 154 is located in the avoidance area.

[0258] When the unlocking part 150 is in the second area, the positioning part 154 separates from the avoidance area.

[0259] In detail, by reasonably setting the structure of the button 130, the button 130 is provided with a notch 138, the notch 138 surrounds an avoidance area, and when the unlocking member 150 is in the first area, the positioning part 154 is located in the avoidance area, and when the unlocking member 150 is in the second area, the positioning part 154 is separated from the avoidance area.

[0260] That is, the avoidance area serves to accommodate the positioning part 154 of the unlocking member 150, so as to reduce the overall size of the unlocking member 150 and the button 130 when the unlocking member 150 is in the first area, thereby reducing the space occupied by the box 110 and facilitating the reasonable layout of other components of the control box device 100.

[0261] Furthermore, such as Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 12 , Figure 13 , Figure 15 , Figure 16 and Figure 20 As shown, a portion of the unlocking member 150 extends out of the button 130 through the avoidance area, and the portion of the unlocking member 150 outside the button 130 forms a toggle protrusion 158.

[0262] Specifically, by reasonably designing the structure of the unlocking component 150, a toggle protrusion 158 is formed on the portion of the unlocking component 150 located outside the housing 110. That is, the toggle protrusion 158 is located on the outer side of the housing 110 and can be exposed. In this way, the user can rotate the toggle protrusion 158 to achieve the purpose of rotating the unlocking component 150 and the housing 110.

[0263] This design makes it easy for the user to hold the unlocking component 150, ensuring the convenience of rotating the unlocking component 150 relative to the housing 110.

[0264] Example 11:

[0265] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, based on embodiment 8, embodiment 11 provides a control box device 100 for a cooking appliance. The cooking appliance includes a door body, the door body includes a door hook 400, and the control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0266] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0267] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0268] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0269] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0270] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0271] The control box device 100 also includes a reset member 180, which is located in the box body 110. The reset member 180 can drive the unlocking member 150 to reset from the second area to the first area.

[0272] The reset component 180 is an elastic reset component.

[0273] The unlocking component 150 includes a positioning part 154, which has a locking channel 152. The resetting component 180 includes a mating section 182, which is connected to one side of the positioning part 154.

[0274] In particular, along the height direction of the box body 110, at least a portion of the positioning part 154 is located above the mating section 182.

[0275] Furthermore, such as Figure 20 As shown, the reset member 180 also includes a support section 186, which is bent from the mating section 182 toward the bottom of the housing 110 so that the mating section 182 is connected to the positioning part 154.

[0276] In detail, by reasonably arranging the structure of the reset member 180, the reset member 180 also includes a support section 186, which is connected to the mating section 182, and the support section 186 is bent from the mating section 182 toward the bottom of the housing 110. The support section 186 has the function of supporting the mating section 182 to ensure the mating dimensions of the mating section 182 and the positioning part 154, so that the mating section 182 and the positioning part 154 are connected.

[0277] Furthermore, the bent arrangement of the mating section 182 enhances the structural strength of the reset member 180, thereby ensuring the effectiveness and feasibility of the support section 186 supporting the mating section 182. This prevents the mating section 182 from tilting and provides effective and reliable structural support for the connection between the mating section 182 and the positioning part 154. This satisfies the requirement that the reset member 180 can drive the unlocking member 150 to reset from the second region to the first region.

[0278] Example 12:

[0279] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, based on Embodiment 7, Embodiment 12 provides a control box device 100 for a cooking appliance. The cooking appliance includes a door body, which includes a door hook 400. The control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0280] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0281] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0282] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0283] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0284] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0285] The control box device 100 also includes a reset member 180, which is located in the box body 110. The reset member 180 can drive the unlocking member 150 to reset from the second area to the first area.

[0286] The reset component 180 is an elastic reset component.

[0287] Furthermore, such as Figure 2 and Figure 3 As shown, the box body 110 is provided with a mounting slot 112. The button 130, the reset component 180 and the unlocking component 150 are all provided in the mounting slot 112, and the unlocking component 150 is located between the button 130 and the reset component 180.

[0288] In detail, by rationally arranging the mating structure of the housing 110, button 130, and reset component 180, the housing 110 is provided with a mounting groove 112, and the button 130, reset component 180, and unlocking component 150 are all located in the mounting groove 112. The button 130 and reset component 180 enclose a mounting area, which serves to accommodate the unlocking component 150. Specifically, the unlocking component 150 is located between the button 130 and the reset component 180.

[0289] In other words, button 130 and reset piece 180 serve to install and fix unlocking piece 150, ensuring the fit dimensions of button 130, reset piece 180 and unlocking piece 150.

[0290] This design, while ensuring the functionality of button 130, reset component 180, and unlocking component 150, increases the mating dimensions of unlocking component 150, button 130, and reset component 180, thereby ensuring the stability and reliability of product assembly.

[0291] Furthermore, such as Figure 2 , Figure 3 , Figure 18 and Figure 19As shown, the box body 110 is also provided with a first opening 114 and a second opening 116, both of which are connected to the mounting groove 112.

[0292] The button 130 also includes a drive rod 140 and a second latch 142, which extends out of the housing 110 through the first opening 114 and abuts against the outer surface of the housing 110.

[0293] The drive rod 140 extends out of the box 110 through the second opening 116. The drive rod 140 is used to drive the door hook 400 from the closed position to the open position.

[0294] The housing 110 also includes a first opening 114 and a second opening 116. The first opening 114 connects to the mounting groove 112, and the second opening 116 also connects to the mounting groove 112. The button 130 further includes a drive rod 140 and a second latch 142. When the button 130 is assembled with the mounting groove 112, the second latch 142 extends out of the housing 110 through the first opening 114 and abuts against the outer surface of the housing 110. In other words, the second latch 142 limits the assembly dimensions of the button 130 and the housing 110, preventing the button 130 from disengaging from the mounting groove 112 and providing reliable structural support for effectively triggering the button 130.

[0295] In addition, the drive rod 140 extends out of the housing 110 through the second opening 116, which means that the drive rod 140 can drive the door hook 400 from the closing area to the opening area.

[0296] Specifically, the groove of the mounting groove 112 is correspondingly set with the first opening 114, that is, the first opening 114 is set at the bottom of the mounting groove 112.

[0297] Specifically, the groove of the mounting groove 112 is correspondingly set with the second opening 116, that is, the second opening 116 is set at the bottom of the mounting groove 112.

[0298] Specifically, there is one drive rod 140 and one second opening 116. Alternatively, there are multiple drive rods 140 and multiple second openings 116, with multiple drive rods 140 arranged at intervals, and each drive rod 140 corresponding to one second opening 116.

[0299] Example 13:

[0300] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, based on embodiment 12, embodiment 13 provides a control box device 100 for cooking appliances. The cooking appliances include a door body, the door body includes a door hook 400, and the control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0301] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0302] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0303] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0304] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0305] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0306] The control box device 100 also includes a reset member 180, which is located in the box body 110. The reset member 180 can drive the unlocking member 150 to reset from the second area to the first area.

[0307] The reset component 180 is an elastic reset component.

[0308] The housing 110 is provided with a mounting slot 112. The button 130, the reset component 180 and the unlocking component 150 are all located in the mounting slot 112. The unlocking component 150 is located between the button 130 and the reset component 180.

[0309] The box body 110 is also provided with a first opening 114 and a second opening 116, both of which are connected to the mounting groove 112.

[0310] The button 130 also includes a drive rod 140 and a second latch 142, which extends out of the housing 110 through the first opening 114 and abuts against the outer surface of the housing 110.

[0311] The drive rod 140 extends out of the box 110 through the second opening 116. The drive rod 140 is used to drive the door hook 400 from the closed position to the open position.

[0312] Furthermore, such as Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 12 , Figure 13 , Figure 15 and Figure 16 As shown, the control box device 100 also includes an elastic element 190, which connects the drive rod 140 and the box body 110. The elastic element 190 is used to reset the button 130.

[0313] In detail, the control box device 100 also includes an elastic element 190, which enables the button 130 to be reset. That is, the elastic element 190 provides power support for the button 130 to be reset.

[0314] When an external force is applied to button 130, button 130 moves toward the interior of housing 110, and elastic element 190 is compressed accordingly.

[0315] When the external force applied to button 130 is removed, button 130 returns to its original position under the action of elastic element 190. This configuration provides effective and reliable structural support for the movement of button 130 relative to housing 110.

[0316] Specifically, the housing 110 is provided with a mounting cavity 119, and a portion of the elastic member 190 is located within the mounting cavity 119.

[0317] Specifically, the box body 110 is provided with a clearance hole 220, which is used to avoid the locking member 160 and prevent interference with the locking member 160.

[0318] Furthermore, such as Figure 1 , Figure 5 , Figure 7 and Figure 9 As shown, the control box device 100 also includes a flap 200, which is rotatably connected to one side of the box body 110. The drive rod 140 drives the door hook 400 to move through the flap 200.

[0319] The control box device 100 also includes a flap 200, which is located on the outside of the box body 110 and is rotatably connected to the box body 110. An external force is applied to the button 130, and the drive rod 140 of the button 130 moves relative to the box body 110. The movement of the drive rod 140 drives the flap 200 to rotate relative to the box body 110. The rotation of the flap 200 can drive the lever 300 of the appliance body (specifically, the cooking appliance includes the appliance body, the door is closably connected to the appliance body, and the appliance body includes the control box device 100) to move. The movement of the lever 300 pushes open the door hook 400, thereby opening the door.

[0320] When the external force applied to button 130 is removed, drive rod 140 resets, drive rod 140 separates from flap 200, flap 200 resets, and lever 300 also resets.

[0321] Example 14:

[0322] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, based on Embodiment 7, Embodiment 14 provides a control box device 100 for a cooking appliance. The cooking appliance includes a door body, the door body includes a door hook 400, and the control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0323] Button 130 is movably connected to box 110. When button 130 moves relative to box 110, it can move door hook 400 from the closed position to the open position.

[0324] The unlocking component 150 is movably connected to the box body 110. When the unlocking component 150 is triggered, it can move from the first area to the second area.

[0325] The locking element 160 is movably connected to the button 130. When the locking element 160 is triggered, it can switch between the third and fourth areas.

[0326] When the unlocking element 150 is in the first region and the locking element 160 is in the third region, the locking element 160 is connected to the unlocking element 150, which can restrict the movement of the button 130.

[0327] When the unlocking member 150 is in the second region, or the locking member 160 is in the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0328] The control box device 100 also includes a reset member 180, which is located in the box body 110. The reset member 180 can drive the unlocking member 150 to reset from the second area to the first area.

[0329] The reset component 180 is an elastic reset component.

[0330] Furthermore, the reset component 180 is detachably connected to the housing 110.

[0331] In detail, the reset component 180 and the box body 110 are detachably connected. That is, the detachment and assembly of the reset component 180 and the box body 110 and the installation area of ​​the reset component 180 relative to the box body 110 can be determined according to the actual situation. This makes it suitable for the use requirements of different models of control box devices 100, and the product has strong adaptability, which improves the performance of the product.

[0332] Furthermore, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 12 , Figure 13 , Figure 15 , Figure 16 and Figure 20 As shown, a positioning block 118 is provided inside the box body 110. The positioning block 118 is located on one side of the unlocking member 150. The positioning block 118 includes a first wall surface 120 and a second wall surface 122. The first wall surface 120 faces the bottom of the box body 110, and the second wall surface 122 is set away from the unlocking member 150.

[0333] The reset component 180 includes a connecting segment 188, which is located inside the housing 110. The connecting segment 188 bypasses the first wall 120 and is connected to the second wall 122 by a fastener 210.

[0334] In detail, the housing 110 is provided with a positioning block 118, and the reset member 180 includes a connecting section 188 located inside the housing 110. The positioning block 118 includes a first wall surface 120 and a second wall surface 122. The first wall surface 120 faces the bottom of the housing 110, and the second wall surface 122 is disposed away from the unlocking member 150.

[0335] By reasonably setting the mating structure between the housing 110 and the reset component 180, the connecting section 188 of the reset component 180 extends into the housing 110, the connecting section 188 bypasses the first wall surface 120, and is connected to the second wall surface 122 by the fastener 210. In other words, the reset component 180 and the housing 110 can be detachably connected by the fastener 210.

[0336] Since a portion of the connecting section 188 is configured to correspond to the first wall surface 120 and another portion of the connecting section 188 is configured to correspond to the second wall surface 122, this configuration increases the mating area between the reset component 180 and the positioning block 118 of the housing 110, enriches the mating angle between the reset component 180 and the positioning block 118, and helps to improve the stability and reliability of the assembly of the reset component 180 and the housing 110.

[0337] Meanwhile, since the connecting segment 188 bypasses the first wall 120 and connects to the second wall 122, that is, the connecting segment 188 is arranged in a bent manner. This arrangement can improve the structural strength of the reset member 180, thereby ensuring the matching dimensions of the reset member 180, the unlocking member 150 and the housing 110, and providing effective and reliable structural support for the reset member 180 to effectively drive the unlocking member 150 to reset from the second region to the first region.

[0338] Example 15:

[0339] A second aspect of the present invention provides a cooking appliance, comprising: an appliance body, the appliance body including a control box device 100 as described in any embodiment of the first aspect; and a door, which is closable and connectable to the appliance body.

[0340] In detail, the cooking utensil includes an utensil body and a door, and the utensil body includes a control box device 100.

[0341] The control box device 100 includes a box body 110, a button 130, an unlocking component 150, and a locking component 160.

[0342] The unlocking component 150 is rotatably connected to the housing 110, and can move from the first area to the second area under the action of external force. The locking component 160 is movably connected to the button 130, and can move from the third area to the fourth area under the action of external force, and can also move from the fourth area to the third area under the action of external force.

[0343] When the unlocking member 150 is in the first area and the locking member 160 is in the third area, the locking member 160 and the unlocking member 150 are connected. The unlocking member 150 and the locking member 160 cooperate to restrict the movement of the button 130. At this time, the door hook 400 cannot be moved from the closed position to the open position by pressing the button 130 to open the door.

[0344] When an external force is applied to the unlocking member 150, causing it to move to the second region and the locking member 160 to be in the third region, the locking member 160 separates from the unlocking member 150, releasing the restriction on the movement of the button 130. When an external force is applied to both the unlocking member 150 and the locking member 160, causing the unlocking member 150 to be in the second region and the locking member 160 to be in the fourth region, the locking member 160 separates from the unlocking member 150, releasing the restriction on the movement of the button 130. When the unlocking member 150 is in the first region and an external force is applied to the locking member 160, causing it to be in the fourth region, the locking member 160 separates from the unlocking member 150, releasing the restriction on the movement of the button 130. In all three cases described above, pressing the button 130 allows it to move relative to the housing 110, driving the door hook 400 from the closed position to the open position, thus opening the door.

[0345] Specifically, opening the door requires two steps. First, pressing the unlocking element 150 moves it relative to the housing 110, rotating it from the first area to the second area. At this point, the unlocking element 150 separates from the locking element 160, releasing the restriction on the movement of the button 130. Second, pressing the button 130 moves it relative to the housing 110, causing the door hook 400 to move from the closed position to the open position. When the unlocking element 150 is in the first area and the locking element 160 is in the third area, the button 130 is restricted from movement, preventing the door from being opened by pressing the button 130. Even pulling the door will not open it; that is, the door will not unlock under external force, thus fundamentally solving the problem of children accidentally unlocking the door. This ensures the safety and reliability of cooking appliances, including the control box device 100.

[0346] Specifically, after the door is locked, the unlocking component 150 is in the first area, and the locking component 160 is in the third area. The unlocking component 150 and the locking component 160 are connected to restrict the movement of the button 130. The door hook 400 of the door is engaged with the positioning component of the appliance body, making it impossible to open the door. At this time, even if a child pulls on the door, it cannot be unlocked. In other words, the button 130 and the unlocking component 150 work together to achieve the function of a child lock. When the door is locked and the unlocking component 150 is in the first area and the locking component 160 is in the third area, the door cannot be opened.

[0347] Specifically, when an external force is applied to the locking member 160, causing the locking member 160 to move to the fourth region, the locking member 160 separates from the unlocking member 150, thereby releasing the movement restriction on the button 130.

[0348] In other words, when the user does not need to use the child lock function, triggering the locking element 160 causes it to move to the fourth zone. The locking element 160 and the unlocking element 150 remain separated, and the unlocking element 150 is inactive at this time. Simply pressing button 130 moves the door hook 400 from the closed position to the open position to open the door. This feature meets different user needs and enhances the product's usability and functionality.

[0349] It is understandable that the unlocking component 150 is movably connected to the housing 110, and the unlocking component 150 and the housing 110 form a whole, with the housing 110 serving as the mounting carrier for the unlocking component 150. The housing 110 can restrict the movement trajectory of the unlocking component 150. Similarly, the locking component 160 is movably connected to the button 130, and the locking component 160 and the button 130 form a whole, with the button 130 serving as the mounting carrier for the locking component 160. The button 130 can restrict the movement trajectory of the locking component 160. When the unlocking component 150 and the locking component 160 are connected, the locking component 160 and the button 130 as a whole cannot move relative to the housing 110; that is, the button 130 cannot be triggered to move relative to the housing 110.

[0350] Specifically, cooking appliances include microwave ovens, ovens, steam ovens or steam-grill combos, etc., which will not be listed here.

[0351] Example 16:

[0352] This invention designs a novel two-step door opening restriction control box device 100, and the two-step door opening restriction of the control box device 100 is releasable. Specifically, the control box device 100 includes a locking component 160, a button 130, an elastic component 190, a flip plate 200, a reset component 180, and an unlocking component 150.

[0353] The locking member 160 is cylindrical in shape. The front of the locking member 160 has a marking part 174, which includes a status marking part 174 and an action direction marking part 174. The back of the locking member 160 is provided with a first buckle 164, which cooperates with the button 130. The first buckle 164 is provided with a slot 170 for limiting the engagement, and the locking member 160 is provided with a protruding locking protrusion 162 structure.

[0354] The locking element 160 is mounted on the button 130. The button 130 has a square structure with a mounting channel 134 in the middle and a protrusion 136 on the inner wall of the mounting channel 134.

[0355] The locking element 160 is snapped into the installation channel 134, and is assembled with the button 130 by the cooperation of the first buckle 164, the slot 170 and the protrusion 136, and the position is defined.

[0356] The button 130 is also provided with a first clearance opening 132 to accommodate the locking protrusion 162, and the first clearance opening 132 can limit the rotation range of the locking member 160.

[0357] The button 130 also has a drive lever 140 and a notch 138. The elastic element 190 is nested on the drive lever 140 of the button 130.

[0358] The unlocking component 150 and the resetting component 180 are connected. The unlocking component 150 extends out of the button 130 through a notch 138 on the button 130. The resetting component 180 has a second clearance opening 184 in the portion corresponding to the locking channel 152. The second clearance opening 184 can be rectangular, circular, elliptical or other shapes, and the locking channel 152 communicates with the second clearance opening 184.

[0359] The locking channel 152 and the second clearance opening 184 are used to accommodate the locking protrusion 162 on the locking member 160.

[0360] The reset component 180 is assembled onto the housing 110 by fasteners 210. The housing 110 has a first opening 114, a second opening 116, a clearance hole, and a receiving cavity. The second opening 116 cooperates with the drive rod 140 of the button 130 for guidance. The button 130 is snapped into the housing 110 and fixed by the second snap 142 and the first opening 114.

[0361] The clearance hole 220 on the housing 110 corresponds to the mounting channel 134 on the button 130 to prevent interference between the button 130 and the housing 110 when it is activated. The positioning hole and the receiving cavity are used for the assembly connection between the unlocking component 150 and the housing 110. In addition, the flip plate 200 is installed on the back of the housing 110, and the interlocking bracket 500 is used to install the lever 300. The lever 300 is rotatably connected to the interlocking bracket 500.

[0362] When the control box device 100 is in the locked state, the slot 170 of the locking member 160 corresponds to the protrusion 136 in the button 130, and the locking protrusion 162 is locked. The locking protrusion 162 passes through the first clearance opening 132 in the button 130 and extends into the locking channel 152 in the unlocking member 150. In the door opening direction, the locking protrusion 162 is obstructed by the locking channel 152. Correspondingly, the button 130 is obstructed in the door opening direction and cannot open the door.

[0363] When the control box device 100 is in the locked state, opening the door requires two steps: the first step is to release the locked state of the button 130, and the second step is to open the door.

[0364] In the first step, when the unlocking component 150 is pressed, the unlocking component 150 moves from the first area to the second area. The locking channel 152 moves away from the locking protrusion 162 along the unlocking direction. Then, in the door opening direction, the obstruction of the locking channel 152 to the locking protrusion 162 disappears. Correspondingly, the obstruction of the button 130 in the door opening direction disappears.

[0365] In the second step, pressing button 130 causes the locking protrusion 162 to move away from the locking channel 152 in the opening direction and obstruct the unlocking member 150 in the unlocking direction, preventing the unlocking member 150 from resetting. Pressing button 130 in the opening direction causes the drive rod 140 of button 130 to lift the flap 200. The flap 200 rotates, prying the lever 300. The lever 300 rotates, lifting the door hook 400, causing the door hook 400 to disengage from its limit position, and the door is opened.

[0366] After the door opening action is completed, button 130 is reset under the restoring force of elastic element 190.

[0367] Correspondingly, the locking protrusion 162 resets along the opening action direction, the obstruction to the unlocking member 150 in the unlocking action direction disappears, the reset member 180 is elastic, and the unlocking member 150 will return from the second region to the first region along the unlocking action direction. At this time, the locking protrusion 162 extends into the locking channel 152.

[0368] When the locking element 160 is in the fourth zone, opening the door requires only one action, specifically:

[0369] Rotating the locking member 160 moves it from the third region to the fourth region, releasing the locking state and thus removing the restriction on opening the door in two steps. The rotation angle of the locking member 160 is determined by the opening size of the first clearance slot 132 in the button 130. Figure 11 and Figure 14 As shown, when the restriction is released, the locking protrusion 162 moves away from the locking channel 152 along the first direction or the second direction, and finally stops reaching the fourth area due to the obstruction of the first clearance opening 132. The slot 170 also moves away from the protrusion 136 along the first direction or the second direction.

[0370] The protrusion 136 will lock the locking member 160 to prevent the locking member 160 from resetting naturally, and the locking protrusion 162 is located in the fourth area.

[0371] In the direction of the door opening action, it is not obstructed by the locking channel 152.

[0372] Button 130 can be pressed directly in the direction of the door opening action without obstruction, thus opening the door in one step, eliminating the need for the initial unlocking step.

[0373] The locking element 160 can also move linearly along the surface of the button 130 to move the locking protrusion 162 away from the locking channel 152.

[0374] The locking element 160 and the button 130 are assembled as one unit. The locking protrusion 162 extends into the locking channel 152 to form an obstruction in the direction of the door opening action, thereby restricting the door opening. Two steps are required to open the door.

[0375] The unlocking action 150 can move the locking channel 152 away from the locking protrusion 162, remove the obstruction to the opening action direction, and realize the first unlocking action. To open the door, the second opening action is required.

[0376] The locking member 160 can move in the direction of the release action, and the locking protrusion 162 moves away from the locking channel 152, releasing the two-step door opening restriction. At this time, only one door opening action is needed to open the door.
