Description

Technical Field

[0001] This application relates to the technical field of household appliances, and particularly to a door structure and a cooking device. Background Art

[0002] Most common cooking utensils do not have a child lock, which may cause children to be scalded when opening the door for various reasons. Therefore, some electric child locks and extremely complex mechanical child locks have emerged on the market. A common drawback of these two types of child locks is that they have a complex structure and high cost. Moreover, cooking utensils with a child lock on the market today are a burden in scenarios where the child lock is not needed. Summary of the Invention

The connecting portion is connected to the clamping member, and the sliding portion is slidably engaged with the connecting portion;

[0008] A handle, which is arranged on the door, and the handle is provided with a locking groove;

[0009] When the clamping member is in the first position, the clamping hook cooperates with the limiting portion and at least a part of the sliding portion is located in the locking groove to limit the displacement of the clamping member;

[0010] When the sliding portion disengages from the locking groove, the switch member drives the clamping member to be movable relative to the door.

[0011] In some embodiments, a holding space is provided between the handle and the door, and the locking groove is provided in the holding space.

[0012] In some embodiments, an included angle exists between the sliding direction of the sliding portion and the moving direction of the clamping member.

[0013] In some embodiments, a part of the connecting portion is located within the holding space, and the sliding portion is in sliding fit with the part of the connecting portion located within the holding space;

[0014] When the sliding portion is disengaged from the locking groove, pull the handle in a direction away from the door body to drive the engaging member to move so that the hook is disengaged from the limiting portion.

[0015] In some embodiments, the surface of the handle facing the door body is the inner surface, and the inner surface includes a first mating surface and a second mating surface. The top wall of the locking groove is connected to the first mating surface, and the bottom wall of the locking groove is connected to the second mating surface to define a stepped surface. The stepped surface is located below the connecting portion to limit the moving displacement of the connecting portion.

[0016] In some embodiments, one of the sliding portion and the connecting portion is provided with a slide rail, and the other of the sliding portion and the connecting portion is provided with a slide groove, and the slide rail and the slide groove are in sliding fit.

[0017] In some embodiments, the sliding portion is formed as a flexible material member to buffer the collision force with the locking groove when the sliding portion extends into the locking groove.

[0018] In some embodiments, the hook is formed as an inverted hook structure bent downward.

[0019] In some embodiments, the hook includes a connecting arm and an engaging portion. The connecting arm is connected to the main body portion of the engaging member, and the engaging portion extends and bends from the end of the connecting arm away from the main body portion toward the door body to form the inverted hook structure.

[0020] In some embodiments, a through hole is provided on the door body, and a part of the engaging member passes through the through hole to be located outside the door body to define the connecting portion.

[0021] In some embodiments, the sliding portion extends obliquely upward from the handle to the door body; or

[0022] The sliding portion extends obliquely downward from the handle to the door body.

[0023] In some embodiments, the door body structure further includes a reset member, and the reset member is respectively connected to the door body and the engaging member, and the reset member provides a force for the engaging member to move from the second position to the first position.

[0024] In some embodiments, the reset member is a spring, and the two ends of the spring are respectively hooked and mated with the door body and the engaging member.

[0025] In some embodiments, the door body structure further includes a shock absorber disposed at the limiting portion. When the clamping member moves to the first position, the shock absorber is configured to buffer the collision force between the door hook and the limiting portion.

[0027] In the door body structure and the cooking device according to the embodiment of the present application, when the clamping member is in the first position, the hook cooperates with the limiting portion and at least a part of the sliding portion is located in the locking groove to limit the displacement of the clamping member, thereby realizing the child lock protection function. This effectively prevents the door of the cooking device from being directly opened by pulling the handle, ensuring the safety of the door opening process of the cooking device and reducing the risk of being scalded by the cooked food when the door is accidentally opened due to misoperation. When the sliding portion is disengaged from the locking groove, the child lock protection function can be unlocked, and the switching member drives the clamping member to be movable relative to the door body to realize the door opening operation. Moreover, since only by sliding the sliding portion can the switching between the child lock protection function and the unlocking of the child lock protection function be realized, compared with the related art that uses an electric child lock and a very complex mechanical child lock, the structure is simple and the cost is reduced.

[0045] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0046] Please refer to Figures 1 to 6 , an embodiment of the present application provides a cooking device 100. The cooking device 100 is used for cooking food. The cooking device 100 includes a door structure 10 and a cabinet 20. The door structure 10 is disposed on the cabinet 20 in an openable and closable manner.

[0047] The cooking device 100 may include, but is not limited to, a microwave oven, a steam oven, an oven, and a combined function model thereof, etc. The cabinet 20 includes a limiting portion 21. The limiting portion 21 is used for limiting the door structure 10, so that the door structure 10 covers the cabinet 20 to form a sealed space for cooking food conveniently.

[0048] The door structure 10 includes a door body 11, a clamping member 12, a switching member 13, and a handle 14.

[0049] Among them, the door body 11 is rotatably arranged on the box body 20, and the clamping member 12 is arranged on the door body 11. The clamping member 12 includes a hook 121, and the hook 121 cooperates or disengages with the limiting portion 21.

[0050] The switch member 13 cooperates with the clamping member 12 to drive the clamping member 12 to be movable between a first position x1 and a second position x2. The switch member 13 includes a connecting portion 132 and a sliding portion 131. The connecting portion 132 is connected to the clamping member 12, and the sliding portion 131 is slidably engaged with the connecting portion 132.

[0051] The handle 14 is arranged on the door body 11, and the handle 14 is provided with a locking groove 141. When the clamping member 12 is in the first position x1, the hook 121 cooperates with the limiting portion 21 and at least a part of the sliding portion 131 is located in the locking groove 141 to limit the displacement of the clamping member 12. When the sliding portion 131 disengages from the locking groove 141, the switch member 13 drives the clamping member 12 to be movable relative to the door body 11.

[0052] In the door body structure 10 and the cooking device 100 of the embodiment of the present application, when the clamping member 12 is in the first position x1, the hook 121 is cooperatively arranged with the limiting portion 21, and at least a part of the sliding portion 131 is located in the locking groove 141, so as to limit the displacement of the clamping member 12, thereby realizing the child lock protection function, effectively avoiding directly realizing the door opening action of the cooking device 100 by pulling the handle 14, ensuring the safety of the door opening process of the cooking device 100, and reducing the risk of being scalded by the cooked food when the door body 11 is opened due to misoperation. When the sliding portion 131 disengages from the locking groove 141, the child lock protection function can be unlocked, and the switch member 13 drives the clamping member 12 to be movable relative to the door body 11 to realize the door opening operation. Moreover, since only the sliding portion 131 needs to be slid to realize the switching between the child lock protection function and the unlocking child lock protection function, compared with the electric child lock and the extremely complex mechanical child lock in the related art, the structure is simple and the cost is reduced.

[0053] In addition, since only the sliding portion 131 of the switch member 13 needs to be slid to realize the switching between the child lock protection function and the unlocking child lock protection function, compared with the electric child lock and the extremely complex mechanical child lock in the related art, the structure is simple and the cost is reduced.

[0054] Specifically, the door body 11 may include two opposite sides, one of which is rotatably connected to the box body 20, and the connection method may be a hinge or a hinge, etc. For example, in some examples, the door body 11 and the box body 20 are rotatably connected by a hinge. The other side of the door body 11 is provided with a clamping member 12, a switch member 13 and a handle 14.

[0055] The clamping member 12 is passed through the door body 11. When the door body 11 is covered on the box body 20, the clamping member 12 is arranged opposite to the limiting portion 21 of the box body 20, and the clamping member 12 includes a hook 121. The hook 121 can partially extend from the door body 11 into the limiting portion 21 and cooperate with the limiting portion 21 to limit the door body 11, thereby ensuring that the door body 11 can be covered on the box body 20 without external force.

[0056] The switch member 13 is disposed on the side of the door body 11 away from the box body 20, and the switch member 13 is connected to the clamping member 12. The switch member 13 can drive the clamping member 12 to move between the first position x1 and the second position x2. The switch member 13 includes a sliding portion 131 and a connecting member, wherein the connecting portion 132 is connected to the clamping member 12, and the sliding member is slidably disposed on the connecting portion 132.

[0057] The handle 14 is fixedly installed on the side of the door body 11 facing away from the box body 20. The user can apply force to the handle 14 to cover the door body 11 on the box body 20 or open the door body 11 from the box body 20. The handle 14 is provided with a locking groove 141 arranged toward the sliding portion 131. When a force is applied to the sliding portion 131 along the direction of the locking groove 141, the sliding portion 131 can at least partially slide into the locking groove 141, thereby limiting the displacement of the clamping member 12, so that the clamping member 12 can cooperate with the limiting portion 21 to form a child lock function. At this time, the handle 14 limits the relative movement of the clamping member 12. Even if a force is applied to the handle 14, the clamping member 12 cannot be separated from the limiting portion 21, ensuring that the door body 11 can cover the box body 20.

[0058] When the door needs to be opened, the sliding portion 131 is slid out of the locking groove 141 to disengage from the locking groove 141. At this time, the handle 14 has no direct restriction on the switch member 13, and the child lock function is unlocked. If the user applies a force to the handle 14 in a direction away from the box body 20 to pull the switch member 13, the switch member 13 drives the clamping member 12, and the clamping member 12 moves from the first position x1 to the second position x2, and the hook 121 disengages from the limiting portion 21, and further pulls the handle 14 or the sliding portion 131, and the door body 11 is driven to disengage from the box body 20 through the handle 14 or the sliding portion 131 to realize the door opening action.

[0059] That is, when the door body structure 10 is opening, the sliding portion 131 needs to be slid out of the locking groove 141 of the handle 14 to disengage the sliding portion 131 from the locking groove 141, ensuring that the handle 14 does not restrict the displacement of the door-opening member and the engaging member 12. Thus, the switching member 13 can drive the engaging member 12 to move from the first position x1 to the second position x2, enabling the hook 121 to disengage from the limiting portion 21, and then the effect of opening the door can be achieved. It can be understood that since the operation of sliding the sliding portion 131 is different from the operation of pulling the handle 14 to pull the door body 11 and requires step-by-step operation, it can better prevent unauthorized personnel such as children from directly opening the door, and the safety performance is good.

[0060] It should be noted that in this embodiment, the arrangement direction of the first position x1 and the second position x2 can be the vertical direction or at a certain angle to the vertical direction. For example, in this embodiment, the arrangement direction of the first position x1 and the second position x2 can be illustrated by taking the vertical direction as an example. That is, the switching member 13 can drive the engaging member 12 to move vertically. And, the first position x1 is located below the second position x2. The second position x2 can be the position where the engaging member 12 is located when the hook 121 just disengages from the limiting portion 21, or the second position x2 can also be the position where the maximum displacement of the engaging member 12 can move from the first position. The rotation direction of the door body 11 can be the horizontal direction, and the rotation direction of the door body 11 is perpendicular to the vertical direction. It can be understood that since the door body 11 needs to be moved vertically to open the door during the opening process, the possibility of misoperation can be reduced. Of course, in some other examples, the movement direction of the engaging member 12 can also be other directions, such as at a certain angle to the vertical direction, that is, as long as the hook 121 can be used to achieve the cooperation with the limiting portion 21.

[0061] In some embodiments, a holding space 15 is provided between the handle 14 and the door body 11, and the locking groove 141 is provided in the holding space 15. The switching member 14 is arranged in the holding space 15, and a part of the engaging member 12 extends from the door body 11 into the holding space 15 and is connected to the connecting portion 122 arranged in the holding space 15. The sliding portion 131 is slidably arranged in the holding space 15, and the locking groove 141 is arranged in the sliding direction of the sliding portion 131, and the opening of the locking groove 141 can be slightly larger than the cross-sectional size of the sliding portion 131 in the sliding direction. In this way, the sliding portion 131 can slide into the locking groove 141 along the sliding direction to limit the displacement of the engaging member 12.

[0062] In some embodiments, there is an angle between the sliding direction of the sliding portion 131 and the moving direction of the engaging member 12.

[0063] The angle between the sliding direction of the sliding part 131 and the moving direction of the engaging part 12 can be an acute angle, a right angle or an obtuse angle, and the specific degree of the angle is not limited. For example, the angle between the sliding direction of the sliding part 131 and the moving direction of the engaging part 12 can be 30°, 45°, 60°, 90°, 120°, 150°, etc.

[0064] In some embodiments, a part of the connecting part 132 is located in the holding space 15, and the sliding part 131 is in sliding fit with the part of the connecting part 132 located in the holding space 15; when the sliding part 131 is disengaged from the locking groove 141, the handle 14 is pulled in a direction away from the door body 11 to drive the engaging part 12 to move so that the hook 121 is disengaged from the limiting part 21.

[0065] Specifically, when the sliding part 131 slides out of the locking groove 141, so that the sliding part 131 is disengaged from the locking groove 141, if the handle 14 is pulled in a direction away from the door body 11, the engaging part 12 can be driven to move from the first position x1 to the second position x2, so that the hook 121 is disengaged from the limiting part 21, so that the door body 11 can be separated from the box body 20 to realize door opening.

[0066] Please refer to Figure 3 and Figure 4 In addition, in some other embodiments, it is also possible to first press the sliding part 131 to drive the engaging part 12 to move from the first position x1 to the second position x2, so that the hook 121 is disengaged from the limiting part 21, and then pull the handle 14 outwards to realize door opening.

[0067] It can be understood that due to the clamping force of the engaging part 12 and the inertia of opening and closing the door, etc., the cooking device 100 usually easily emits extremely loud noises, which interfere with users. Especially when used in the quiet morning or late at night, it will affect the sleeping family members. Due to the existence of these scenarios, it is extremely inconvenient and even limits the use of the cooking device 100. By pressing the sliding part 131, the sliding part 131 presses against the connecting part 132 to drive the engaging part 12 to move from the first position x1 to the second position x2. In this way, the direction of the clamping and unclamping forces can be transferred to the normal direction of the movement of the door body 11 to ensure that the hook 121 can be disengaged from the limiting part 21. When the user applies a force away from the box body 20 to the handle 14 to open and close the door, a door opening and closing without resistance can be realized, avoiding the impact collision between the hook 121 and the limiting part 21 due to the clamping force of the hook 121 and the limiting part 21 and the inertia of the door opening force, etc., resulting in noise, realizing noise reduction during door opening and closing, improving the user experience, and moreover, due to reducing the collision impact between the hook 121 and the limiting part 21, the damage to the hook 121 and the limiting part 21 is reduced, thereby prolonging the service life of the hook 121 and the limiting part 21.

[0068] In addition, in some other embodiments, other methods can also be adopted to achieve the movement of the engaging member 12 between the first position x1 and the second position x2. For example, a cam or a lever structure is used to press against the engaging member 12, so that the engaging member 12 moves from the first position x1 to the second position x2, and then the handle 14 or the sliding member 131 is pulled to achieve silent opening and closing of the door.

[0069] Please refer to Figure 7 , in some embodiments, the surface of the handle 14 facing the door body 11 is the inner surface 142. The inner surface 142 includes a first mating surface 1421 and a second mating surface 1422. The top wall 1411 of the locking groove 141 is connected to the first mating surface 1421, and the bottom wall 1411 of the locking groove 141 is connected to the second mating surface 1422 to define a stepped surface (not shown in the figure). The stepped surface is located below the connecting portion 132 and is used to limit the moving displacement of the connecting portion 132.

[0070] The first mating surface 1421 is arranged parallel to the moving direction of the engaging member 12. When a force is applied to the sliding portion 131 in the moving direction of the engaging member 12, the sliding member 131 abuts against the connecting portion 132, thereby driving the engaging member 12 to slide along the first mating surface 1421. The stepped surface formed by the connection between the bottom wall 1411 of the locking groove 141 and the second mating surface 1422 can limit the moving range of the engaging member 12. When the connecting portion 132 abuts against the stepped surface, the engaging member 12 can be located at the first position x1, and the hook 121 cooperates with the limiting portion 21.

[0071] In some embodiments, one of the sliding portion 131 and the connecting portion 132 is provided with a sliding rail, and the other of the sliding portion 131 and the connecting portion 132 is provided with a sliding groove, and the sliding rail and the sliding groove are in sliding fit.

[0072] For example, in some examples, the sliding portion 131 is provided with a sliding rail, and the connecting portion 132 is provided with a sliding groove, and the sliding rail and the sliding groove are arranged in sliding fit, so that. Again, for example, in other examples, one of the connecting portions 132 is provided with a sliding rail, and the sliding portion 131 is provided with a sliding groove, and the sliding rail and the sliding groove are arranged in sliding fit.

[0073] In some embodiments, the sliding portion 131 is formed as a flexible material member to buffer the collision force with the locking groove 141 when the sliding portion 131 extends into the locking groove 141.

[0074] In this way, the noise generated by the collision impact when the sliding portion 131 extends into or out of the locking groove 141 can be reduced, the noise reduction of opening and closing the door is achieved, and the user experience is improved.

[0075] In some embodiments, the hook 121 is formed as a barbed structure that bends downward. When the door body 11 is closed, the limiting portion 21 is caught at the barb of the hook 121, so that the limiting portion 21 cooperates with the hook 121 to limit the movement of the door body 11.

[0076] Specifically, the limiting portion 21 is arranged below the hook 121. When the door body 11 is closed, the engaging member 12 moves from the second position x2 to the first position, so that the limiting portion 21 is caught at the barb of the hook 121, ensuring the cooperation between the limiting portion 21 and the hook 121. When the handle is pulled, the limiting portion 21 and the hook 121 abut against each other in the direction of the door rotation, thereby restricting the movement of the door body 11 and ensuring that the door body 11 can cover the box body 20 without external force.

[0077] The hook 121 can be one or more. For example, the number of hooks 121 can be 1, 2, 3, 4 or even more. That is, the number of hooks 121 is not limited. In the embodiments of the present application, the door body structure 10 including two hooks 121 is taken as an example for illustration. It should be noted that taking the door body structure 10 including two hooks 121 as an example for illustration is for the convenience of understanding the embodiments of the present application and should not be construed as a limitation of the present application.

[0078] In some embodiments, the hook 121 includes a connecting arm 1211 and a engaging portion 1212. The connecting arm 1211 is connected to the main body portion 122 of the engaging member 12, and the engaging portion 1212 bends and extends from the end of the connecting arm 1211 away from the main body portion 122 toward the door body 11 to form a barbed structure.

[0079] Specifically, the engaging member 12 includes a hook 121 and a main body portion 122. Among them, the hook 121 and the main body portion 122 can be an integrally formed structure. For example, the hook 121 and the main body portion 122 can be made of a metal plate by stamping or other methods. It can be understood that the main body portion 122 and the hook 121 are made by stamping a metal plate, making the hook 121 more reliable and durable, capable of avoiding deformation of the hook 121, and being beneficial to the processing of the main body portion 122 and the hook 121. In this way, the stability of the hook 121 arranged on the main body portion 122 can be effectively improved, and the stability of the cooperation relationship between the hook 121 and the limiting portion 21 is ensured. Of course, in other embodiments, the hook 121 can also be connected to the main body portion 122 by other connection methods such as welding, bonding or screws. That is, the specific connection method between the hook 121 and the main body portion 122 is not limited.

[0080] When the engaging member 12 is in the first position x1, the engaging portion 1212 is engaged with the limiting portion 21 to limit the door body 11, ensuring that the door body 11 can cover the box body 20 without external force. When the engaging member 12 moves from the first position x1 to the second position, the engaging portion 121 disengages from the limiting portion 21.

[0081] Please further combine with Figure 2 , in some embodiments, a through hole 111 is provided on the door body 11, and a part of the clamping member 12 passes through the through hole 111 to be located outside the door body 11 to define a connecting portion 132.

[0082] Specifically, a part of the main body portion 122 passes through the through hole 111 from the door body 11 to be connected to the connecting portion 132 located outside the door body 11. In this way, the clamping member 12 can be driven to move from the first position x1 to the second position x2 by pressing the sliding portion 131, so that the hook 121 is disengaged from the cooperation with the limiting portion 21.

[0083] Please combine with Figure 3 , in some embodiments, the sliding portion 131 extends obliquely upward in the direction from the handle to the door body 11.

[0084] Specifically, the included angle between the sliding direction of the sliding portion 131 and the moving direction of the clamping member 12 is an acute angle, so that the sliding portion 131 extends obliquely upward in the direction from the handle to the door body 11. For example, in some examples, the included angle between the sliding direction of the sliding portion 131 and the moving direction of the clamping member 12 is 60°. In this way, when at least a part of the sliding portion 131 extends into the locking groove 141, it can be avoided that the sliding portion 131 slides out of the locking groove 141 without external force, ensuring the limitation of the clamping member 12.

[0085] In some embodiments, the sliding portion 131 extends obliquely downward in the direction from the handle to the door body 11.

[0086] Specifically, the included angle between the sliding direction of the sliding portion 131 and the moving direction of the clamping member 12 is an obtuse angle, so that the sliding portion 131 extends obliquely downward in the direction from the handle to the door body 11. For example, in some examples, the included angle between the sliding direction of the sliding portion 131 and the moving direction of the clamping member 12 is 150°.

[0087] In some embodiments, the direction of the sliding portion 131 from the handle to the door body 11 is perpendicular to the moving direction of the clamping member 12.

[0088] In some embodiments, the door body structure 10 further includes a reset member 16, the reset member 16 is respectively connected to the door body 11 and the clamping member 12, and the reset member 16 provides a force for the clamping member 12 to move from the second position x2 to the first position x1.

[0089] Understandably, during the process of opening the door, the engaging member 12 needs to move from the first position x1 to the second position x2, so that the limiting portion 21 releases the limitation on the hook 121. When the door needs to be closed, the engaging member 12 needs to move from the second position x2 to the first position x1, so that the hook 121 cooperates with the limiting portion 21. Therefore, the reset member 16 provides a force for the engaging member 12 to move from the second position x2 to the first position x1, so that the engaging member 12 is effectively at the first position x1, ensuring the cooperation between the hook 121 and the limiting portion 21, further reducing misoperation, and improving the use safety.

[0090] In some embodiments, the reset member 16 is a spring, and the two ends of the spring are respectively hooked and cooperated with the door body 11 and the engaging member 12.

[0091] When the door needs to be closed, the elastic force of the spring can be used to pull the engaging member 12 from the second position x2 to the first position x1, so that the hook 121 of the engaging member 12 cooperates with the limiting portion 21. When the door needs to be opened, it is necessary to press the sliding portion 131 to drive the engaging member 12 to move from the first position x1 to the second position x2, and overcome the elastic force of the spring, thereby increasing the opening force of the door, further reducing misoperation, and improving the use safety. In other embodiments, the reset member 16 can also be other elastic components, as long as the engaging member 12 can be more stably clamped on the limiting portion 21.

[0092] In some embodiments, the door body structure 10 further includes a shock-absorbing member 17, and the shock-absorbing member 17 is arranged on the limiting portion 21. When the engaging member 12 moves to the first position x1, the shock-absorbing member 17 is used to buffer the collision force between the hook 121 and the limiting portion 21.

[0093] In this way, the noise generated by the impact collision between the hook 121 and the limiting portion 21 due to the inertial effect during opening and closing the door is reduced, the noise reduction during opening and closing the door is achieved, and the user experience is improved.
