[0039] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] The following is for reference. Figures 1-11 The door lock structure 100 of the cooking appliance according to an embodiment of the present invention has a child lock function, which makes it difficult for children to open the door 300 in case of accidental contact, thereby reducing the probability of children being burned and improving the safety and reliability of the product.

[0041] Among them, such as Figure 1As shown, the cooking device 1000 includes a housing 200 and a door 300. The housing 200 is typically rectangular in structure, and a cooking cavity is formed within it. An opening is formed on the front side wall of the housing 200 corresponding to the cooking cavity. The door 300 is closable and engages with the housing 200, and is used to selectively close the opening of the cooking cavity. The user can open the door 300 and place the food to be heated into the cooking cavity through the opening. After the food is stably placed, the user closes the door 300 to close the opening, allowing the cooking device 1000 to heat the food. After heating, the user can open the door 300 to remove the heated food for consumption.

[0042] It should be noted that a locking structure is used for selective locking between the door 300 and the cabinet 200. Specifically, the door 300 has a door hook, and the cabinet 200 has a limiting part. When the limiting part and the door hook are locked, the door 300 and the cabinet 200 are locked, ensuring that the door 300 will not open on its own. Existing locking structures typically use pull-to-unlock or press-to-unlock methods, requiring relatively little unlocking force and making the unlocking process too simple. Children can easily open the door 300, which could result in burns if there is heated food inside the cooking cavity. To solve the above problems, this invention provides a door lock structure 100. The door lock structure 100 according to this invention can be used to implement a child lock function between the door 300 and the cabinet 200 to prevent the above-mentioned situation from occurring.

[0043] like Figure 1-11 As shown, the door lock structure 100 according to an embodiment of the present invention includes: a first flipping member 1, a pushing member 2, a resetting member 3, and a second flipping member 4.

[0044] The first flipping member 1 is rotatably mounted on the housing 200, and one end of the pushing member 2 is rotatably mounted on the first flipping member 1. The first flipping member 1 rotates in a first direction to drive the pushing member 2 to switch from a first state to a second state. Specifically, as shown... Figures 1-2 As shown, one end of the first flipping member 1 can be rotatably fixed to the housing 200, while the other end of the first flipping member 1 can move relative to the housing 200. The user drives the other end of the first flipping member 1 to rotate the first flipping member 1 relative to the housing 200. At the same time, the pusher 2 is installed on the rear side of the first flipping member 1 (i.e., the side facing the cooking cavity). One end of the pusher 2 is rotatably connected to the first flipping member 1, and the other end of the pusher 2 can move relative to the first flipping member 1. When the first flipping member 1 rotates in the first direction, the first flipping member 1 can drive the pusher 2 to switch from the first state to the second state.

[0045] More specifically, a first flipping member 1 can be arranged to extend vertically, with its upper end rotatably fixed to the housing 200. The front end of the pusher 2 is rotatably connected to the first flipping member 1, and the rear end of the pusher 2 can move relative to the first flipping member 1. When the user drives the first flipping member 1 to rotate around its upper end relative to the housing 200, the rear end of the pusher 2 can move relative to the first flipping member 1 to switch from the first state to the second state.

[0046] The reset member 3 is connected to the other end of the pusher 2 and the first flipper 1, respectively. The reset member 3 applies a force toward the pusher 2 to reset towards the first state. Specifically, as shown... Figure 4 As shown, the rear end of the pusher 2 can be connected to the first flipper 1 by the reset member 3. When the first flipper 1 rotates to switch the pusher 2 to the second state, the reset member 3 is used to apply a force to the pusher 2 to reset towards the first state. When the external force on the first flipper 1 disappears, the reset member 3 can drive the pusher 2 to reset towards the first state, ready for the next action.

[0047] More specifically, the reset member 3 can be set as a spring. When the pusher 2 switches to the second state, the spring is in a stretched state and is used to apply a force to the pusher 2 to restore it to the first state.

[0048] The second flipper 4 is rotatably disposed on the housing 200. In the first state, the pusher 2 is disengaged from the second flipper 4. In the second state, the pusher 2 cooperates with the second flipper 4 to push the second flipper 4 to rotate to the open position. In the open position, the second flipper 4 drives the door hook of the door 300 to separate from the limiting part of the housing 200.

[0049] Specifically, such as Figure 3 As shown, the second flipper 4 is located on the rear side of the pusher 2, and one end of the second flipper 4 is rotatably mounted on the housing 200, while the other end of the second flipper 4 can move relative to the housing 200. The second flipper 4 is used to cooperate with the door hook on the door 300. When the second flipper 4 rotates in the second direction, the second flipper 4 can drive the door hook of the door 300 and the limiting part of the housing 200 to separate, so as to unlock the door 300 and the housing 200.

[0050] Among them, such as Figure 2 As shown, when the pusher 2 is in the first state, the rear end of the pusher 2 is disengaged from the second flipper 4. Thus, when the user pushes the first flipper 1 to rotate, the pusher 2 cannot drive the second flipper 4 to move, and the second flipper 4 can remain in its current position, thereby preventing direct pressing for unlocking. Figures 5-6As shown, when the pusher 2 is in the second state, the rear end of the pusher 2 cooperates with the second flipper. By pushing the first flipper 1 to move, the second flipper 4 can be rotated to the open position, thereby unlocking the door 300 and the box 200.

[0051] In the specific operation process, when the door 300 and the housing 200 are closed, the pusher 2 is in the first state. The user can pull the first flipper 1 to rotate in the first direction, causing the first flipper 1 to drive the pusher 2 to move and switch to the second state. The reset member 3 is in the stretched state. At this time, the pusher 2 cooperates with the second flipper 4. The user can push the first flipper 1 to move, driving the pusher 2 to push the second flipper 4 to rotate to the open position, thereby unlocking the door hook of the door 300 and the limiting part of the housing 200. After unlocking, the user releases the first flipper 1, the reset member 3 pulls the pusher 2 to switch to the first state, and the second flipper 4 can be reset under the action of gravity.

[0052] According to the door lock structure 100 of the present invention, by driving the first flipping member 1 to move in the first direction, the pushing member 2 is switched to the second state. After the pushing member 2 is switched to the second state, the first flipping member 1 is driven to move again, so as to push the second flipping member 4 to rotate to the open position, thereby unlocking the door 300 and the cabinet 200. The unlocking process is simple and stable, and a child lock function is implemented, so that children cannot open the door 300 in case of accidental touch, thus improving the safety of children.

[0053] In some embodiments of the present invention, in a second state, the pusher 2 pushes the first flipper 1 in a second direction so that the pusher 2 pushes the second flipper 4 to rotate. The first and second directions can be set to be opposite, for example, the first direction can be set to be away from the housing 200, and the second direction can be set to be close to the housing 200.

[0054] Specifically, such as Figures 2-8 As shown, when the door 300 and the housing 200 are closed, the pusher 2 is in the first state. The user can pull the first flipper 1 to rotate away from the housing 200. The first flipper 1 drives the pusher 2 to move, and the rear end of the pusher 2 moves downward to switch to the second state. The reset member 3 is in the stretched state. At this time, the pusher 2 cooperates with the second flipper 4. The user can push the first flipper 1 to move closer to the housing 200. The pusher 2 pushes the second flipper 4 to rotate to the open position, so that the door hook of the door 300 and the limiting part of the housing 200 are unlocked. After unlocking, the user releases the first flipper 1, the reset member 3 pulls the pusher 2 to switch to the first state, and the second flipper 4 can be reset under the action of gravity. Thus, the unlocking process of the door lock structure 100 is simple and convenient, with a good unlocking feel, which helps to improve user satisfaction.

[0055] In some embodiments of the present invention, in a first state, the pusher 2 and the second flipper 4 are misaligned; in a second state, the pusher 2 and the second flipper 4 are directly opposite each other.

[0056] Specifically, such as Figure 2 As shown, when the pusher 2 is in the first state, the rear end of the pusher 2 is offset from the second flipper 4. This way, when the user pushes the first flipper 1 to rotate in the second direction, the pusher 2 cannot drive the second flipper 4 to move, and the second flipper 4 can remain in its current position, thus preventing direct pressing for unlocking. Figures 5-6 As shown, when the pusher 2 is in the second state, the rear end of the pusher 2 is supported on the second flipper 4 or located in front of the second flipper 4. By pushing the first flipper 1 to move in the second direction, the second flipper 4 can be rotated to the open position, thereby unlocking the door 300 and the box 200.

[0057] More specifically, the upper end of the second flipper 4 is rotatably connected to the housing 200, and the lower end of the second flipper 4 can move relative to the housing 200. When the pusher 2 is in the first state, the pusher 2 is tilted backward and upward, with its rear end offset from the second flipper 4. The front end of the pusher 2 is supported on the first flipper 1. When the first flipper 1 rotates in the second direction, it cannot drive the second flipper 4 to rotate, and the second flipper 4 remains in its current position to avoid accidental unlocking. When the first flipper 1 moves in the first direction, the rear end of the pusher 2 moves downward. When the pusher 2 switches to the second state, its rear end presses against the second flipper 4. At this time, pushing the first flipper 1 in the second direction will push the second flipper 4 to the open position, thereby unlocking the door 300 and the housing 200.

[0058] Therefore, the pusher 2 cannot move the second flipper 4 in the first state, and the pusher 2 can stably drive the second flipper 4 to move in the second state, which helps to improve the reliability and stability of the door lock structure 100.

[0059] In some embodiments of the present invention, the surface of the second flipping member 4 facing the first flipping member 1 is a pushing surface; in the first state, the pushing member 2 is inclined relative to the pushing surface; in the second state, the pushing member 2 is perpendicular to the pushing surface.

[0060] Specifically, such as Figure 2-7As shown, a pushing surface can be provided on the front side of the second flipper 4. The pushing surface extends vertically. When the pushing member 2 is in the first state, the pushing member 2 is tilted backward and upward, and the pushing member 2 is offset from the pushing surface. At this time, it is impossible to move the second flipper 4 by pushing the first flipper 1 to the second direction. However, when the pushing member 2 switches to the second state, the pushing member 2 extends horizontally, and the rear end of the pushing member 2 is vertically supported on the pushing surface. At this time, by pushing the first flipper 1 to move in the second direction, the second flipper 4 can be moved to the opening position in the second direction, thereby unlocking the box 200 and the door 300. The unlocking process is stable and reliable, and the feedback is good.

[0061] In some embodiments of the present invention, such as Figure 3 As shown, the door lock structure 100 of the cooking device in this embodiment of the invention also includes a damper 6. The damper 6 is disposed on the first flipping member 1 and connected to the pushing member 2. The damper 6 provides a damping force to reduce the speed at which the pushing member 2 rotates toward the first state.

[0062] Specifically, such as Figure 2 As shown, the damper 6 is fixed to the first flipper 1, and the damping rod 61 of the damper 6 is connected to the pusher 2. When the pusher 2 is in the first state, the damper 6 and the reset member 3 are in the initial state. When the pusher 2 switches to the second state, the reset member 3 switches to the stretched state, and the damper 6 is in the working state. At this time, when the user removes the force applied to the first flipper 1, the reset member 3 applies a reset force to the pusher 2, causing the pusher 2 to reset to the first state. The damper 6 can apply a damping force opposite to the reset force to the pusher 2 to slow down the speed at which the pusher 2 rotates to the first state. In this way, the pusher 2 can be prevented from colliding with other parts and generating noise, which helps to reduce the operating noise of the door lock structure 100 and improve user satisfaction.

[0063] More specifically, such as Figure 11 As shown, a clearance hole 22 can be provided in the middle of the pusher 2. The clearance hole 22 is used to avoid the damping rod 61. The damping rod 61 extends to the side of the pusher 2 away from the damper 6. The side wall of the clearance hole 22 is connected to a connecting flange 21 extending towards the side away from the damper 6. The connecting flange 21 has a connecting hole that passes through in the thickness direction. A fixing hole is provided at the end of the damping rod 61 away from the first flipper 1. After the damping rod 61 passes through the clearance hole 22, the fixing hole and the connecting hole are aligned. The bolt 8 can pass through the connecting hole, the fixing hole and another connecting hole in sequence to realize the detachable installation of the damping rod 61 and the pusher 2.

[0064] In some embodiments of the present invention, the door lock structure 100 of the cooking device of the present invention further includes a fixed bracket 5, the fixed bracket 5 is fixed to the first flipping member 1, and the damper 6 is fixed on the fixed bracket 5.

[0065] Specifically, such as Figure 4 and Figure 10 As shown, the fixed bracket 5 has a fixed part 52, which is used to connect with the first flipping member 1, and the fixed bracket 5 extends towards the direction close to the pushing member 2. By fixing the damper 6 to the fixed bracket 5, it is convenient to adjust the position and angle of the damper 6 relative to the pushing member 2, so that the damper 6 can be better connected with the pushing member 2, which helps to improve the deceleration effect of the damper 6 when the pushing member 2 switches to the first state, and reduces the operating noise of the door lock structure 100.

[0066] More specifically, a through hole can be provided on the fixed part 52, and an inwardly open threaded hole is provided on the rear side of the first flipping member 1. When the fixed bracket 5 is installed on the first flipping member 1, the fixed part 52 fits against the rear side of the first flipping member 1 and the through hole and the threaded hole are directly opposite each other. The connecting member passes through the through hole and extends into the threaded hole, so that the fixed bracket 5 can be detachably installed on the first flipping member 1.

[0067] In some embodiments of the present invention, the reset member 3 is fixed to the fixing bracket 5. Specifically, as shown in the figure... Figure 2 , Figure 4 and Figure 10 As shown, a hook 54 is provided on the upper side of the fixed bracket 5. One end of the reset member 3 is connected to the hook 54 of the fixed bracket 5, and the other end of the reset member 3 is connected to the rear end of the push member 2. This helps to reduce the length of the reset member 3 and reduces the interference of external components on the reset member 3, so that the reset member 3 can remain stable during the extension and retraction process, thereby improving the reliability of the reset member 3.

[0068] In some embodiments of the present invention, the surface of the first flipping member 1 facing the second flipping member 4 is provided with a mounting boss 11, the fixing bracket 5 is fixed to the mounting boss 11, and a placement space is defined between the fixing bracket 5 and the mounting boss 11. The damper 6 is placed in the placement space, and the damping rod 61 of the damper 6 extends out of the placement space and is connected to the pusher 2.

[0069] Specifically, such as Figure 9 As shown, a rearwardly protruding mounting boss 11 can be provided on the rear sidewall of the first flipping member 1, and a rearwardly and downwardly open receiving groove is provided in the middle of the mounting boss 11. The fixing bracket 5 is set according to the shape of the rear sidewall of the mounting boss 11, and the fixing bracket 5 can fit and support the rear sidewall of the mounting boss 11, and a placement space is formed between the fixing bracket 5 and the mounting boss 11. The placement space has a downwardly open opening, and the damper 6 is used to install in the placement space. The damping rod 61 of the damper 6 can extend out of the placement space from the opening, thereby connecting with the pusher 2.

[0070] Understandably, by placing the damper 6 in the placement space, the rationality of the layout of the door lock structure 100 is improved, which is conducive to the miniaturization design of the door lock structure 100 and reduces external interference to the damper 6, so that the damper 6 can decelerate when the pusher 2 rotates to the first state, thereby effectively reducing the noise of the door lock structure 100.

[0071] In some embodiments of the present invention, the mounting boss 11 is provided with an inclined support surface 113, the inclined support surface 113 is downward and extends inclinedly toward the second flipping member 4, the fixing bracket 5 includes a contact portion 51, the contact portion 51 abuts against the inclined support surface 113, and the reset member 3 and the damper 6 are respectively fixed to the contact portion 51.

[0072] Specifically, such as Figure 9 As shown, the mounting boss 11 includes a fixing boss 111 and a supporting boss 112. The rear side of the fixing boss 111 has a mounting plane, and the mounting plane has a threaded hole opening to the rear. The supporting boss 112 is connected to the lower side of the fixing boss 111, and the rear side of the supporting boss 112 has an inclined support surface 113 that faces downwards and backwards. Wherein, as... Figure 10 As shown, the fixed bracket 5 includes a fixed part 52 and a contact part 51. The fixed part 52 and the contact part 51 are bent and connected. The fixed part 52 can fit against the rear side of the fixed protrusion 111 and is detachably connected to the fixed protrusion 111. The contact part 51 is used to fit against the inclined support surface 113 to increase the contact area between the fixed bracket 5 and the mounting protrusion 11, thereby improving the installation stability of the fixed bracket 5.

[0073] More specifically, such as Figure 10 As shown, abutting flanges 53 can be provided on both sides of the contact portion 51. The abutting flanges 53 extend toward the direction close to the first flipping member 1, and the two abutting flanges 53 are used to support the two side walls of the mounting boss 11 respectively, so as to improve the installation stability of the fixed bracket 5.

[0074] In some embodiments of the present invention, the first flipping member 1 is provided with a first guide portion, and the blocking member 2 is provided with a second guide portion. The first guide portion and the second guide portion cooperate to guide the rotation direction of the blocking member 2. Specifically, the first flipping member 1 may be provided with a first guide portion, and the blocking member 2 may be provided with a corresponding second guide portion. The second guide portion may engage with the first guide portion for limiting. In this way, when the blocking member 2 switches from a first state to a second state, or from a second state to a first state, the first guide portion can guide the rotation direction of the blocking member 2, preventing the blocking member 2 from deviating and getting stuck, improving the movement stability of the blocking member 2, reducing the noise generated during the movement of the blocking member 2, and improving the user experience.

[0075] In some embodiments of the present invention, the first guide portion is a plate 12 provided on the first flipping member 1, and the second guide portion is a groove 21 provided on the blocking member 2. Specifically, as shown in the figure... Figure 9 As shown, the first flipping member 1 has plates 12 extending towards the rear on both sides, and both plates 12 are configured as first guide parts, and as shown... Figure 11 As shown, the blocking member 2 has inwardly recessed grooves 21 on both sides, and the two grooves 21 correspond to the two plates 12 one by one. With the above arrangement, when the blocking member 2 rotates, the plate 12 of the first flipping member 1 can slide relative to the grooves 21 of the blocking member 2 to guide the blocking member 2, avoid the blocking member 2 from deviating and getting stuck, and improve the movement stability of the blocking member 2.

[0076] In some embodiments of the present invention, such as Figure 1-5 As shown, the door lock structure 100 of the cooking device in this embodiment of the invention includes a box body 7. The box body 7 is fixed to the housing 200. The front surface of the box body 7 is provided with a flipping space. A first flipping member 1 is rotatably assembled to the box body 7 and located within the flipping space. A second flipping member 4 is rotatably installed inside the box body 7 and located behind the first flipping member 1.

[0077] Specifically, such as Figure 1 As shown, the box body 7 can be constructed as a rectangular structure. The box body 7 is fixed to one side of the opening of the box body 200 and is used to connect with the door body 300. The front surface of the box body 7 is provided with a through hole that runs through the thickness direction. A flipping space is formed in the through hole. The first flipping member 1 is set in the flipping space, and the upper end of the first flipping member 1 is rotatably fixed on the box body 7, so that the first flipping member 1 can rotate in the flipping space.

[0078] The second flipper 4 includes a main body 41 and two connecting parts 42. The two connecting parts 42 are respectively disposed on both sides of the main body 41 and are rotatably connected to the two inner side walls of the box 7, so as to rotatably install the second flipper 4 inside the box 7. The second flipper 4 is located behind the first flipper 1. Thus, when the pusher 2 is in the second state, pushing the first flipper 1 backward can push the second flipper 4 to move backward, thereby unlocking the box 200 and the door 300.

[0079] It is understandable that by setting up the housing 7 and integrating the other components of the door lock structure 100 into the housing 7, the housing 7 can protect the other components, thereby improving the overall stability of the door lock structure 100 and giving the door lock structure 100 a higher aesthetic appeal.

[0080] In some embodiments of the present invention, such as Figure 4As shown, when the first flipper 1 is not rotated, its front surface is flush with the front surface of the box 7. Specifically, when the pusher 2 is in the first state, i.e., when unlocking the door 300 and the box 200 is not required, the front surface of the box 7 and the front surface of the first flipper are smoothly connected, making the door lock structure 100 aesthetically pleasing and reducing its inducing effect on children, thus reducing the possibility of accidental activation by children and improving the safety of the door lock structure 100. Figure 5 As shown, when the pusher 2 is in the second state, the first flipper 1 protrudes from the front surface of the box body 7, which helps to improve the user's feedback when unlocking.

[0081] The present invention also proposes a cooking device 1000.

[0082] The cooking device 1000 according to an embodiment of the present invention includes: a housing 200, a door 300, and a door lock structure 100. The housing 200 is provided with a limiting part, the door 300 is provided on the housing 200 in an openable and closable manner, the door 300 is provided with a hook, the door lock structure 100 is the door lock structure 100 of any of the above embodiments, the first flipping member 1 and the second flipping member 4 are rotatably provided on the housing 200, when the second flipping member 4 rotates to the open position, the second flipping member 4 drives the door hook to separate from the limiting part.

[0083] Specifically, such as Figure 1 As shown, the cooking device 1000 includes a housing 200 and a door 300. The housing 200 is typically rectangular in structure, and a cooking cavity is formed within it. An opening is provided on the front side wall of the housing 200 corresponding to the cooking cavity. The door 300 is closable and engages with the housing 200, selectively closing the opening of the cooking cavity. The user can open the door 300 and place the food to be heated into the cooking cavity through the opening. After the food is stably placed, the user closes the door 300 to close the opening, allowing the cooking device 1000 to heat the food. After heating, the user can open the door 300 to remove and consume the heated food. The door 300 and housing 200 are selectively locked using a locking structure. Specifically, the door 300 has a door hook, and the housing 200 has a limiting part. When the limiting part and door hook are locked, the door 300 and housing 200 are locked together, ensuring that the door 300 will not open by itself. Meanwhile, the first flipper 1 and the second flipper 4 are rotatably disposed on the box 200. The second flipper 4 is used to connect with the limiting part of the box 200. When the second flipper 4 rotates to the door opening position, the door hook separates from the limiting part, and the door 300 can move relative to the box 200 to open the opening of the box 200.

[0084] More specifically, when the door 300 and the housing 200 are closed, the pusher 2 is in the first state. The user can pull the first flipper 1 to rotate away from the housing 200. The first flipper 1 drives the pusher 2 to move, and the rear end of the pusher 2 moves downward to switch to the second state. The reset member 3 is in the stretched state. At this time, the lower end of the pusher 2 is supported on the second flipper 4. The user can push the first flipper 1 to move closer to the housing 200. The pusher 2 pushes the second flipper 4 to rotate, thereby unlocking the door hook of the door 300 and the limiting part of the housing 200. After unlocking, the user releases the first flipper 1, the reset member 3 pulls the pusher 2 to switch to the first state, and the second flipper 4 can reset under the action of gravity.

[0085] According to an embodiment of the present invention, the cooking device 1000 drives the first flipping member 1 to move in a first direction, thereby driving the pushing member 2 to switch to a second state. After the pushing member 2 switches to the second state, the first flipping member 1 is driven to move in a second direction to push the second flipping member 4 to rotate to the open position, thereby unlocking the door 300 and the cabinet 200. The unlocking process is simple and stable, and a child lock function is implemented, so that children cannot open the door 300 in case of accidental touch, which improves the safety of the cooking device 1000 and helps to improve user satisfaction.
