A door lock structure 10 of a cooking apparatus 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1 to 10, according to the door lock structure 10 of the cooking apparatus 1 according to the embodiment of the present invention, the cooking apparatus 1 includes a cabinet 32 and a door 31, and the door lock structure 10 includes a flip member 20, a first reset member 14, a defining member 12, and a second reset member 15.

The door 31 and the box 32 can be matched in an opening and closing mode, so that the box 32 can be opened and closed through the door 31. When a user needs to use the cooking device 1, the door 31 can be operated to open the box 32, food can be placed in the box 32, the box 32 can be closed through the door 31, and the cooking device 1 can be used for cooking the food.

The turnover part 20 is rotatably disposed on the box body 32, and when the turnover part 20 is triggered to rotate to the door opening position, the turnover part 20 drives the hook of the door body 31 to disengage from the limiting portion of the box body 32, and at this time, the door body 31 can open the box body 32.

That is to say, the user can change the matching relationship between the hook and the limiting part by operating the flip part 20, and then the door 31 can move from the position of closing the box 32 to the position of opening the box 32, so as to close or open the box 32 according to the user's requirement. Specifically, when the door 31 closes the box 32, the hook on the door 31 cooperates with the position-limiting part on the box 32 to ensure that the door 31 is in a state of closing the box 32. After the user operates the turnover part 20, the hook on the door body 31 can be disengaged from the limiting part on the box body 32, and at this time, the door body 31 can move to the position for opening the box body 32.

The first restoring member 14 is connected to the turning member 20 and the box 32, respectively, so that the first restoring member 14 provides a first restoring force to the turning member 20, wherein the first restoring force is toward the non-activated position, so as to ensure that the turning member 20 can be automatically restored to the non-activated position after the user releases the turning member 20, and the user can operate the turning member 20 next time.

The limiting piece 12 can be movably arranged on the box body 32 between a first position and a second position, the limiting piece 12 blocks the turning piece 20 from rotating towards the door opening position at the first position, at the moment, when a user operates the turning piece 20, because the limiting piece 12 blocks the turning piece 20 from rotating, the hook of the door body 31 and the limiting part on the box body 32 are still in a matching state, and at the moment, the door body 31 cannot move to the position for opening the box body 32.

When limiting piece 12 is in the second position, limiting piece 12 can dodge the rotation of upset 20, and when the user operated upset 20, upset 20 can move to the state of opening the door, and then drive the pothook of door 31 and the spacing portion on the box 32 and break away from the cooperation, and door 31 can move to the position of opening box 32 this moment.

The door lock structure 10 thus configured can achieve double locking of the door 31, and specifically, when the door 31 needs to be opened to the cabinet 32, the user needs to move the limiting member 12 to the second position and move the turnover member 20 to the door-opened state. Need just can open box 32 through step operation to avoid children's mistake to touch to open box 32 and be scalded.

The second reset member 15 is connected to the limiting member 12 and the housing 32, respectively, so that the second reset member 15 is used for providing a second restoring force to the limiting member 12, wherein the second restoring force is movable toward the first position, so as to keep the limiting member 12 always capable of blocking the turnover member 20 from moving toward the door-opening position, and the key 111 needs to be operated each time to move the limiting member 12 to the second position. The door body 31 can be opened only by step operation, and the door body 31 is prevented from being opened due to mistaken touch.

The door lock structure 10 is configured such that the return speed of the turning member 20 toward the unfired position under the action of the first return force is greater than the return speed of the limiting member 12 moving from the second position toward the first position, so that the limiting member 12 can return from the turning member 20, and the limiting member 12 prevents the turning member 20 from rotating toward the unfired position when the limiting member 12 moves from the second position toward the first position, and prevents the two from being jammed during the moving process. That is, when the box 32 needs to be opened, the user can first move the limiting member 12 to the second position, then operate the turning member 20 to move to the door-opening state, and then when the user releases the turning member 20 and the limiting member 12 at the same time, the turning member 20 is preferentially reset to the non-triggering position under the driving of the first resetting member 14, so that the limiting member 12 is successfully reset to the first position after the turning member 20 is reset to the non-triggering position, and the two blocking surfaces are blocked in the resetting process.

Specifically, by providing the door lock structure 10, on the one hand, when the door 31 of the cooking apparatus 1 is opened, the user needs to first release the operation of the restricting member 12 to contact the restricting member 20. Then, the door body 31 can be opened only by operating the turnover part 20 to release the limitation between the hook and the limiting part, so that the problem that a child mistakenly touches the door lock structure 10 to directly open the door body 31 can be avoided, and the use safety of the cooking equipment 1 is improved. On the other hand, the door lock structure 10 according to the embodiment of the present invention has a simple structure and low cost, and is advantageous to simplify the manufacturing process of the cooking apparatus 1 and reduce the manufacturing cost of the cooking apparatus 1. On the other hand, the door lock structure 10 of the embodiment of the invention is convenient to operate and convenient for users to use, so that the user experience is better.

Therefore, according to the door lock structure 10 of the cooking device 1 in the embodiment of the present invention, the door body 31 can be locked, when the door body 31 of the cooking device 1 is opened, the limitation of the door lock structure 10 needs to be removed first, and then the switch lock needs to be opened, so that the problem that a child mistakenly touches the switch lock device to directly open the door body 31 can be avoided, and the safety of the use of the cooking device 1 can be improved.

A door lock structure 10 of a cooking apparatus 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1 to 10, the cooking apparatus 1 includes a cabinet 32 and a door 31, and the door lock structure 10 includes a flip member 20, a first reset member 14, a defining member 12, and a second reset member 15.

Specifically, cooking devices 1 such as microwave ovens, electric steamers, electric ovens, etc. have become electrical appliances commonly used in modern household life. When the heating of the food in the cooking apparatus 1 is completed, the food is in a high temperature state. Most cooking devices 1 can open the door by pulling the door handle or the button 111, and the door opening force is less than 25N. Under the mechanism, for families with children, in the using process of the cooking device 1, the children may touch the door opening key 111 or the handle by mistake, the door opening can be completed by lightly pressing or lightly pulling, and the risk of scalding the heated food exists. In order to solve the above problem, referring to fig. 1 to 3, an embodiment of the present invention provides a door lock structure 10 of a cooking apparatus 1 for the cooking apparatus 1.

In some embodiments of the present invention, the door 31 is rotatably connected to the cabinet 32, and the door 31 rotates relative to the cabinet 32 to open or close the cabinet 32. The door 31 and the cabinet 32 may be, but not limited to, rotatably connected by a hinge, as long as the two can be rotatably connected together. In addition, in some embodiments, the door 31 may be non-detachably connected to the box 32, so that the cooking apparatus 1 has better structural integrity, is more firmly installed, and is more beautiful. In other embodiments, the door 31 may be detachably connected to the box 32, so that if the structure inside the box 32 is damaged, the door 31 can be detached from the box 32 for maintenance.

In some embodiments of the present invention, the first restoring member 14 is a tension spring, and a user can press the reversing member 20 to rotate the reversing member 20 backward (the front and back directions are shown in fig. 1), at this time, the first restoring member 14 is elastically deformed and elongated, and after the user releases the first restoring member 14, the first restoring member 14 can pull the reversing member 20 to rotate forward with a larger pulling force, so that the first restoring member 14 always has a forward pulling force on the reversing member 20, so as to ensure that after the user releases the reversing member 20, the first restoring member 14 always has enough force to drive the reversing member 20 to return to the non-triggered position, so that the user can directly operate the reversing member 20 next time.

In some embodiments of the present invention, the second resetting member 15 is a compression spring, the user can drive the limiting member 12 to move rightwards, at this time, the second resetting member 15 is elastically deformed and compressed, after the user releases the second resetting member 15, the second resetting member 15 can push the limiting member 12 to move forwards with a larger pushing force, so that the second resetting member 15 always has a leftward pushing force on the limiting member 12 (the left and right directions are shown in fig. 1), it is ensured that after the user does not operate the limiting member 12, the second resetting member 15 always has enough force to drive the limiting member 12 to move to the first position, so that the limiting member 12 is in a position of obstructing the flip member 20 from moving towards the door-open position, and the user needs to perform a secondary operation every time the user opens the box body 32.

In some embodiments of the present invention, the door lock structure 10 of the cooking apparatus 1 further comprises a damping member 133, the damping member 133 is connected to the limiting member 12 and the cabinet 32, respectively, and the damping member 133 provides a damping force to reduce the return speed of the movement of the limiting member 12 toward the first position, thereby prolonging the time for returning the limiting member 12. The flipper 20 is reset to the unactuated position during the period of time when the restricting member 12 is moved from the second position to the first position.

In some embodiments, the user can move the limiting member 12 from the first position to the second position, and after the user releases the limiting member 12, the second resetting member 15 will not immediately drive the limiting member 12 to reset to the first position under the blocking of the damping member 133, but will stay in the first position for a period of time. During this period of time, the user may operate the flipper 20 to rotate the flipper 20 to the open door position to open the bin 32.

The damping member 133 is provided to reduce the operation difficulty of the user, for example, when the user can only operate the door lock structure 10 with one hand, the damping member 133 can be provided to perform the step-by-step operation in different time periods, that is, the limiting member 12 and the turning member 20 do not need to be operated simultaneously, and the limiting member 12 can be operated first with one hand, and then the turning member 20 is operated to rotate the turning member 20 to the door opening position to open the box body 32.

In some embodiments of the present invention, the first restoring force is greater than the second restoring force, so that the resetting speed of the rotation of the tilting member 20 towards the non-triggered position is greater than the resetting speed of the movement of the limiting member 12 from the second position towards the first position, so that the limiting member 12 can be reset from the tilting member 20, and the limiting member 12 can prevent the tilting member 20 from rotating towards the non-triggered position and being blocked during the movement when the limiting member 12 moves from the second position towards the first position.

In some embodiments of the present invention, the limiting piece 12 includes a first abutting portion 121, the flip-up piece 20 includes a second abutting portion 221, and at the first position, the second abutting portion 221 abuts against at least a portion of the first abutting portion, so that the limiting piece 12 can block the rotation of the flip-up piece 20, and the hook of the door 31 and the limiting portion on the box 32 are still in a matching state, and the door 31 cannot be moved to a position for opening the box 32.

In the second position, the second abutting portion 221 is completely displaced from the first abutting portion 121, so that the restricting piece 12 can escape the rotation of the tumbler 20, and the tumbler 20 can smoothly rotate to the door opening position.

In some specific embodiments of the present invention, the limiting member 12 further includes a first avoiding portion 122 corresponding to the second abutting portion 221, the first avoiding portion 122 is disposed in a staggered manner with respect to the first abutting portion 121, the flip-up member 20 further includes a second avoiding portion 222 corresponding to the first abutting portion 121, the second avoiding portion 222 is disposed in a staggered manner with respect to the second abutting portion 221, in the second position, the first abutting portion 121 penetrates into the second avoiding portion 222, and the second abutting portion 221 penetrates into the first avoiding portion 122, so that the limiting member 12 can avoid the rotation of the flip-up member 20.
