In order to solve the above problem, referring to fig. 1 to 4, an embodiment of the present invention provides a door lock device 100 of an electric cooking appliance 1000. The cooking appliance 1000 includes a case 300, and the case 300 is provided with a locking part 301. The door-lock apparatus 100 includes a snap 10 and a restricting member 20. The latch 10 is movably disposed on the door 200, the latch 10 includes a hook 11, and the hook 11 is engaged with or disengaged from the locking portion 301. The limiting assembly 20 is disposed on the door body 200, and the limiting assembly 20 includes a rotating member 21, and the rotating member 21 can rotate relative to the clamping member 10 to switch between a locking state and an unlocking state. When the rotating member 21 is switched to the unlocking state, the rotating member avoids the clamping member 10, and the clamping member 10 can move in the first direction D1 to be separated from or matched with the locking portion 301; when the rotating member 21 is switched to the locked state, the rotating member 21 is used to limit the moving displacement of the engaging member 21 in the first direction D1, so that the hook 11 is kept engaged with the locking portion 301.

According to the door lock device 100, the limiting assembly 20 is arranged on the door body 200, the rotating piece 21 in the limiting assembly 20 can enable the rotating piece 21 to be switched between the locking state and the unlocking state, and under the condition that the rotating piece 21 is in the locking state, the rotating piece 21 can limit the moving displacement of the clamping piece 10 in the first direction D1, so that the clamping hook 11 is kept to be matched with the locking part 301, the door body 200 is kept on the box body 300, and a user is prevented from easily opening the door body 200 particularly without misoperation of a child accompanied by an adult. When a user needs to open the door body 200, the rotating member 21 needs to be rotated first, so that the rotating member 21 is in an unlocking state; after the clamping member 10 loses the limiting effect of the rotating member 21, the door body 200 is normally opened again at this time (for example, the door body 200 is directly pulled or the door opening key is pressed), and the clamping member 10 can move in the first direction D1 to be separated from the locking portion 301, so that the door body 200 is opened from the box body 300. Since the user needs to rotate the rotating member 21 before opening the door 200, that is, the step of opening the door 200 is added, the door 200 can be prevented from being easily opened due to misoperation, and thus the safety of the user using the cooking appliance 1000 can be improved.

Specifically, the latch 10 is movably provided on the door body 200. The clamping member 10 includes a first side and a second side opposite to each other, and the first side is closer to the rotating member 21 than the second side. The first direction D1 is a direction from the second side to the first side, and the opposite direction of the first direction D1 is a direction from the first side to the second side. Hereinafter, the first direction D1 and the first direction D1 are also the same, and will not be described in detail.

The clip 10 includes a hook 11, and the hook 11 can be engaged with or disengaged from the locking portion 301, so that the clip 10 can be engaged with or disengaged from the locking portion 301. Under the condition that the clamping piece 10 is matched with the locking part 301, the hook 11 is matched with the locking part 301, so that the door body 200 can be kept closed on the box body 300; when the clip 10 is disengaged from the lock portion 301, the hook 11 is disengaged from the lock portion 301, and the door 200 can be opened from the case 300.

It should be noted that, during the process of engaging the clip 10 with the locking portion 301 or during the process of disengaging the clip 10 from the locking portion 301, the clip 10 needs to move a certain distance in the first direction D1. Specifically, as shown in fig. 2, the locking portion 301 is provided with a receiving space and a blocking piece 302, and the blocking piece 302 includes an inclined surface inclined toward a side close to the clip 10. In the process of matching the clamping piece 10 with the locking portion 301, the hook 11 in the clamping piece 10 moves towards the accommodating space along the inclined plane of the blocking piece 302, and when the hook 11 moves beyond the end of the inclined plane close to the accommodating space, the hook 11 falls into the accommodating space, so that the hook 11 is hooked on the blocking piece 302, thereby realizing the matching of the hook 11 and the locking portion 301, namely realizing the matching of the clamping piece 10 and the locking portion 301. It can be understood that, in the process that the hook 11 moves towards the accommodating space along the inclined surface of the blocking piece 302, the hook 11 moves a certain distance in the first direction D1, that is, the clip 10 also moves a certain distance in the first direction D1; during the process that the hook 11 falls into the accommodating space, the hook 11 moves a certain distance in the direction opposite to the first direction D1, that is, the clip 10 also moves a certain distance in the direction of the first direction D1. Similarly, during the process of disengaging the card member 10 from the locking portion 301, the hook 11 needs to move a certain distance in the first direction D1, i.e. in a direction away from the blocking piece 302, so as to disengage from the blocking piece 302, and then the hook 11 moves along the inclined surface of the blocking piece 302 in a direction away from the receiving space, so as to disengage the hook 11 from the locking portion 301. It can be understood that, in this process, the clip 10 also needs to be moved to the first direction D1 for displacement to disengage the clip 10 from the locking portion 301.

In some embodiments, the clip 10 can include two hooks 11, and the locking portion 301 has two blocking pieces 302 respectively matching with the two hooks 11 to lock the hooks 11 and the locking portion 301.

In some embodiments, the end of the hook 11 has a hook surface that can engage with the flap 302. When a user applies a pulling force to the door body 200 to open the door body 200, the hook surface of the hook 11 slides along the end portion of the blocking piece 302 until the end portion of the hook 11 is higher than the end portion of the blocking piece 302.

As shown in fig. 5 and 6, the rotating member 21 in fig. 5 and 6 is in the locked state. In some embodiments, when the rotating member 21 is in the locked state, at least a portion of the structure of the rotating member 21 is located in the moving path of the engaging member 10 in the first direction D1, and the rotating member 21 is spaced from the engaging member 10 in the first direction D1 by less than a predetermined distance. In the process of disengaging the clip 10 from the locking portion 301, the distance that the clip 10 moves in the first direction D1 is a predetermined distance.

Because at least part of the structure of the rotating member 21 is located in the moving path of the clamping member 10 in the first direction D1, the rotating member 21 can limit the moving displacement of the clamping member 10 in the first direction D1, that is, the clamping member 10 can not move any more after moving in the first direction D1 until the rotating member 21 collides. In addition, since the interval between the rotating member 21 and the engaging member 10 in the first direction D1 is smaller than the predetermined distance, the displacement of the engaging member 10 in the first direction D1 is insufficient to disengage the engaging member 10 from the locking portion 301, so that the door 200 cannot be opened from the cabinet 300.

In some embodiments, when the rotating member 21 is in the locked state, at least a portion of the rotating member 21 abuts against the engaging member 10 to limit the movement of the engaging member 10. For example, in some embodiments, the rotation member 21 includes an interference portion 211, in a case where the rotation member 21 is in the locked state, the interference portion 211 is located above the clip 10, and the interference portion 211 abuts against the clip 10 to limit the movement of the clip 10.

In particular, in some embodiments, in the case that the rotating member 21 is in the locked state, the interference portion 211 is located above the snap member 10, that is, the interference portion 211 is located within the moving path of the snap member 10 in the first direction D1, and there is a gap between the interference portion 211 and the snap member 10 in the first direction D1, and the gap is smaller than the predetermined distance. Thus, on the one hand, the clamping piece 10 can be kept matched with the locking part 301; on the other hand, because there is the interval between conflict portion 211 and the joint spare 10, compare in conflict portion 211 directly contradicts with joint spare 10, conflict portion 211 and joint spare 10 can not produce the friction when rotating a piece 21, are favorable to the user more easily to rotate a piece 21 to in order to promote the user and use the experience of locks 100 and feel.

As shown in fig. 2, 3, 7, and 8, the rotor 21 in fig. 2, 3, 7, and 8 is in an unlocked state. In some embodiments, with the rotation piece 21 in the unlocked state, the rotation piece 21 is located outside the movement path of the snap member 10 in the first direction D1. In this way, in the case where the rotation member 21 is in the unlocked state, the rotation member 21 cannot restrict the movement displacement of the clip 10 in the first direction D1, that is, the clip 10 can move in the first direction D1, so that the clip 10 can be engaged with or disengaged from the lock portion 301.

Referring to fig. 3 and 4, in some embodiments, the limiting assembly 20 may further include a transmission member 22 and a force applying member 23, the force applying member 23 is rotatably connected to the transmission member 22, and the force applying member 23 can rotate relative to the door body 200 to drive the rotating member 21 to rotate. In this way, the user can indirectly rotate the rotating member 21 by rotating the urging member 23 to switch the rotating member 21 between the unlocked state and the locked state.

Specifically, referring to fig. 3 and 4, in some embodiments, one end of the transmission member 22 is fixedly connected to the rotation member 21, and the other end is fixedly connected to the force application member 23. The connection manner of the transmission member 22, the rotation member 21 and the force application member 23 includes, but is not limited to, snap connection, screw connection, adhesive connection, etc., and is not limited herein. For example, in one example, one end of the transmission member 22 extends into the mounting hole 212 of the rotating member 21 and is in interference fit with the mounting hole 212 of the rotating member 21, so that the transmission member 22 can be fixedly connected with the rotating member 21; the other end of the transmission member 22 extends into a mounting hole (not shown) of the force application member 23 and is in interference fit with the mounting hole of the force application member 23, so that the transmission member 22 can be fixedly connected with the force application member 23.

Referring to fig. 3 and 4, in some embodiments, the limiting assembly 20 may further include a support 24 and a first elastic member 25. The support 24 is provided on the door body 200, and both ends of the first elastic member 25 are connected to the support 24 and the rotation member 21, respectively. The first elastic member 25 serves to provide a restoring force to the rotation member 21 rotating toward the locked state when the rotation member 21 is in the unlocked state.

Specifically, the support 24 is located on one side of the force application element 23 close to the rotation element 21, and one end of the transmission element 22 is connected to the rotation element 21, and the other end passes through the support 24 and is connected to the force application element 23. The first elastic member 25 is sleeved on the transmission member 22, and a first elastic arm of the first elastic member 25 is connected to the support 24, and a second elastic arm of the first elastic member 25 is connected to the rotation member 21. The first elastic member 25 transmits elastic deformation in the case where the rotation member 21 is in the unlocked state, and the first elastic member 25 serves to provide a restoring force for the rotation member 21 to rotate toward the locked state. So after the rotating member 21 rotates to the unlocking state, the first elastic member 25 can provide restoring force to the rotating member 21, so that the rotating member 21 automatically rotates to the locking state, thereby avoiding the user from forgetting to rotate the rotating member 21 back to the locking state after use, and being beneficial to further improving the safety of the user in using the door lock device 100.

Referring to fig. 3 and 4, in some embodiments, the door lock device 100 further includes a limiting component 30. The limiting assembly 30 is arranged on the door body 200. The limiting assembly 30 has a limiting state and an avoiding state, and when the hook 10 is separated from the locking part 301 (as shown in fig. 2) and the rotating member 21 is in the unlocking state, the limiting assembly is switched to the limiting state to limit the rotating member 21 from rotating from the unlocking state to the locking state; when the limit member 30 is switched to the avoidance state, the limit member 30 avoids the rotation of the rotating member 21.

Since the card member 10 needs to be moved in the first direction D1 in the process of closing the door, i.e., in the process of engaging the card member 10 with the locking portion 301, the engagement of the card member 10 with the locking portion 301 can be normally completed. When the joint 10 separates from the locking portion 301, if the rotation member 21 rotates to the locking state under the action of the restoring force of the first elastic member 25, the user needs to rotate the rotation member 21 to the unlocking state before closing the door to enable the joint 10 to be matched with the locking portion 301. However, in the present embodiment, on one hand, when the hook 10 is separated from the locking portion 301 and the rotating element 21 is in the unlocking state, the limiting assembly 30 is switched to the limiting state to limit the rotating element 21 from the unlocking state to the locking state, so that the user can directly close the door without rotating the rotating element 21, thereby facilitating the user to use the door lock device 100; on the other hand, when the limiting component 30 is switched to the avoiding state, the limiting component 30 avoids the rotation of the rotating member 21, so that the rotating member 21 can be freely switched between the locking rotation state and the unlocking state.

Specifically, in some embodiments, referring to fig. 3 and 4, the limiting component 30 includes a limiting block 31. The stopper 31 can move relative to the door body 200 to switch between a first position and a second position, wherein the first position is closer to the clamping member 10 than the second position. As shown in fig. 2 and fig. 3, in the limiting state, the limiting block 31 is located at the first position, and the limiting block 31 abuts against the rotating member 21; as shown in fig. 5 to 8, in the avoidance state, the stopper 31 is in the second position to avoid the rotation of the rotation member 21. It should be noted that, in some embodiments, when the stopper 31 is located at the second position, the stopper 31 is located outside the rotation path of the rotating member 21. Thus, when the stopper 31 is located at the second position, the rotation of the rotating member 21 is not blocked, so that the rotating member 21 can be switched between the unlocking state and the locking state.

In some embodiments, the door body 200 is provided with a guide groove, one side of the stopper 31 close to the door body 200 is provided with a combining member 314 capable of being matched with the guide groove, and when the stopper 31 is switched between the first position and the second position, the combining member 314 can move in the guide groove.

In some embodiments, the stopper 31 is located at one side of the clip 10, and when the clip 10 moves, the stopper 31 is pushed to move, so that the stopper 31 is switched between the first position and the second position. Specifically, as shown in fig. 7 and 8. Fig. 7 and 8 are schematic views of 100 components of the door lock device when the door 200 is closed in the box 300 and the rotor 21 is in the unlocked state. At this time, when the engaging member 10 is engaged with the locking portion 301 and the rotating member 21 is in the unlocked state, the engaging member 10 can move in the first direction D1.
