[0008] a resilient member arranged between the second locking member and the machine body;

[0009] The door body comprises a closed state and an open state relative to the machine body; when the door body switches from the open state to the closed state, the door body moves towards the machine body and drives the second locking member to rotate forward to a locked position locked with the first locking member through the first locking member; the second locking member is kept in the locked position under the action of the resilient member and keeps the door body in the closed state;

[0010] When the door body switches from the closed state to the open state, the door body moves away from the machine body and drives the second locking member to rotate reversely to an unlocked position separated from the first locking member through the first locking member; and the second locking member is kept in the unlocked position under the action of the resilient member.

[0011] Further scheme: the machine body is provided with a micro switch, and the second locking member is provided with a micro switch trigger part;

[0012] When the door body is in the closed state, the microswitch trigger part triggers the microswitch; when the door body is in the open state, the microswitch trigger part is separated from the microswitch.

[0013] Based on the above technical scheme: through the above setting, when the door body is closed in place, the second locking member is driven to rotate forward to the locking position, so that the microswitch trigger part triggers the microswitch; when the door is opened, the second locking member is rotated to the unlocking position by the door body, and the microswitch trigger part is separated from the microswitch, that is, the power is cut off when the door is opened, so that the microwave leakage can be avoided, and the safety is higher.

[0014] Further scheme: the door body and the machine body are connected in front and back slidingly.

[0015] Based on the above technical scheme: the above setting makes the door body available for the pull-out type inner pot, which is convenient for users to use.

[0018] Based on the above technical scheme: by setting the first abutting part and the second abutting part, when the second locking member is in the unlocking position and the user closes the door body, the first abutting part drives the second locking member to rotate to the locking position by abutting on the second abutting part, so that the second locking part is locked with the first locking part.

[0019] Further scheme: the first locking part is a lock hole, and the second locking part is a lock block.

[0020] When the door body is in the closed state, the lock block is inserted into the lock hole; when the door body is in the open state, the lock block is separated from the lock hole.

[0021] Based on the above technical scheme: the above setting makes it convenient to drive the second locking member to rotate during the process of opening and closing the door, so that the lock block rotates into the lock hole or separates from the lock hole.

[0022] Further scheme: the first abutting part is the rear end part of the first locking member; the second abutting part is a supporting leg provided on the second locking member and located at the rear side of the lock block; when the door body is in the closed state, the rear end part of the first locking member is located between the lock block and the supporting leg.

[0023] Based on the above technical scheme: the first locking member is driven to rotate by abutting against the supporting leg when the door body is closed, so that the locking block is smoothly inserted into the locking hole; when the door body is opened, the locking hole drives the second locking member to reverse rotate to the unlocking position, so that the locking block is smoothly separated from the locking hole.

[0024] Further scheme: the machine body is provided with a guide groove extending in the front-rear direction, and the first locking member is in sliding connection with the guide groove.

[0025] Further scheme: the elastic member is a torsion spring, the machine body is provided with a first torsion spring connecting portion, the second locking member is provided with a second torsion spring connecting portion, and the two supporting arms of the torsion spring are in rotational connection with the first and second torsion spring connecting portions, respectively.

[0026] When the door body is in the closed state, the torsion spring swings to the first position and gives the second locking member a forward force to keep the second locking member in the locking position; when the door body is in the open state, the torsion spring swings to the second position and gives the second locking member a reverse force to keep the second locking member in the unlocking position.

[0027] Based on the above technical scheme: through the above arrangement, the torsion spring is always in the energy storage state, so as to drive the second locking member to keep in the locking position when in the first position and keep in the unlocking position when in the second position.

[0028] Further scheme: a limiting assembly is arranged between the second locking member and the machine body.

[0029] Further scheme: the limiting assembly comprises an arc-shaped hole arranged on the second locking member and a limiting block arranged on the machine body, and the limiting block is located in the arc-shaped hole.

[0030] When the second locking member is positively rotated from the unlocking position to the locking position, the arc-shaped hole is positively rotated around the limiting block to make the rear side wall of the arc-shaped hole abut against the limiting block.

[0031] When the second locking member is reversely rotated from the unlocking position to the locking position, the arc-shaped hole is reversely rotated around the limiting block to make the front side wall of the arc-shaped hole abut against the limiting block.

[0032] Based on the above technical scheme: the limiting assembly is used to avoid the continuous positive rotation of the second locking member when in the locking position, and avoid the over-rotation of the second locking member when in the unlocking position, so that the first locking member cannot be recombined with the second locking member when the door is closed.

[0033] The beneficial effects of the utility model are:

[0034] The utility model discloses a first locking piece is set up on the door body, and the second locking piece is rotatably arranged on the body, so that when the user closes the door, the door body moves towards the body, and the door body drives the second locking piece to rotate forward to the locking position of locking with the first locking piece through the first locking piece, at this time, under the action of the elastic member, the second locking piece keeps the door body in the closed state through locking with the first locking piece, thereby ensuring that the door is closed in place and avoiding risks, when the user opens the door, the door body is pulled towards the direction of moving away from the body, at this time, because the first locking piece and the second locking piece are locked, so the second locking piece is driven to rotate reversely to the unlocking position of separating from the first locking piece, and then the door body can be smoothly pulled out, and the second locking piece keeps in the unlocking position under the action of the elastic member, facilitating closing the door body next time.

It should be understood that the specific embodiments described herein are only used to explain the utility model and not used to limit the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0046] As shown in Figures 1 to 4 the embodiment, a switch door limiting device on a cooking utensil is provided, which comprises:

[0047] The door body 2 is provided with a first locking member 21.

[0048] The body 1 is provided with a second locking member 12 rotating on the body 1; and

[0049] The elastic member is arranged between the second locking member 12 and the body 1.

[0050] The door body 2 comprises a closed state and an open state relative to the body 1; when the door body 2 is switched from the open state to the closed state, the door body 2 moves towards the body 1 and drives the second locking member 12 to rotate forward to a locking position locked with the first locking member 21 through the first locking member 21; the second locking member 12 is kept in the locking position under the action of the elastic member and the door body 2 is kept in the closed state.

[0051] When the door body 2 is switched from the closed state to the open state, the door body 2 moves away from the body 1 and drives the second locking member 12 to rotate reversely to an unlocking position disengaged from the first locking member 21 through the first locking member 21; and the second locking member 12 is kept in the unlocking position under the action of the elastic member.

[0052] The switch door limiting device described in the embodiment can be applied to cooking appliances such as microwave ovens and ovens. The door body 2 and the machine body 1 can be arranged in a front-rear sliding connection. Specifically, the machine body 1 is provided with a receiving cavity, and the door body 2 is connected with a pull-out type inner pot which enters and exits the receiving cavity in a front-rear sliding manner. The door body 2 is provided with a door handle 22 for facilitating user operation. The machine body 1 is provided with a guide groove 16 extending in the front-rear direction, and the first locking member 21 is in sliding connection with the guide groove 16. Specifically, when the door body 2 is closed, the first locking member 21 slides rearward along the guide groove 16. When the door body 2 is opened, the first locking member 21 slides forward along the guide groove 16. The machine body 1 is provided with a clearance hole for the first locking member 21 to pass through and located on the front side of the guide groove 16. After the first locking member 21 passes through the clearance hole, it slides along the guide groove 16.

[0053] As a specific embodiment, as shown in Figures 1 to 4 When it is applied to a microwave oven or a microwave heating appliance, in order to make the product safer, the machine body 1 is provided with a micro switch 15, and the second locking member 12 is provided with a micro switch trigger part 124.

[0054] When the door body 2 is in a closed state, the micro switch trigger part 124 triggers the micro switch 15, that is, in the process of closing the door, the first locking member 21 drives the second locking member 12 to rotate to a locking position, and the micro switch trigger part 124 rotates with the second locking member 12 to a position triggering the micro switch 15, that is, the microwave heating can be started only after the door is closed in place, thereby preventing microwave leakage. When the door body 2 is in an open state, the micro switch trigger part 124 is separated from the micro switch 15. Specifically, in the process of opening the door, since the first locking member 21 and the second locking member 12 are locked with each other, pulling the door body 2 outward will drive the second locking member 12 to rotate to an unlocking position, and at the same time, the micro switch trigger part 124 rotates with the second locking member 12 to a position separating from the micro switch 15, that is, the door is opened and power is cut off, thereby preventing microwave leakage caused by mistaken operation of opening the door.

[0055] In some specific embodiments, as shown in Figures 1 to 7 The first locking member 21 is provided with a first locking part and a first abutting part 212, and the second locking member 12 is provided with a second locking part and a second abutting part.

[0056] When the door body 2 is switched from an open state to a closed state, the door body 2 moves towards the machine body 1, and the first abutting part 212 drives the second locking member 12 to rotate from an unlocking position to a locking position by abutting on the second abutting part, and the second locking part is locked with the first locking part.

[0057] In the embodiment, as shown in Figures 1 to 7As shown, the first locking part is a locking hole 211, and the second locking part is a locking block 122. Specifically, the second locking member 12 is located on the upper side of the first locking member 21, and the elastic member is located on the upper end of the second locking member 12.

[0058] When the door body 2 is in the closed state, the locking block 122 is inserted into the locking hole 211, that is, in the process of closing the door, with the rotation of the second locking member 12, the locking block 122 is gradually inserted into the locking hole 211 until the door body 2 is completely closed, and the second locking member 12 is rotated to the locking position. At this time, under the action of the elastic member, the locking block 122 abuts against the rear side wall of the locking hole 211, so that the door body 2 is kept in the closed state. When the door body 2 is in the open state, the locking block 122 is separated from the locking hole 211. Specifically, when the door body 2 is pulled outward, the locking hole 211 is locked with the locking block 122 to drive the second locking member 12 to rotate reversely. When the locking block 122 is separated from the locking hole 211 upward, that is, rotated to the unlocking position. At this time, under the action of the elastic member, the second locking member 12 is kept in the unlocking position, and the locking block 122 is located above the locking hole 211.

[0059] The first locking part can also be a slot or a locking hook, and the second locking part can also be a locking hook, so as to cooperate with the first locking part to realize unlocking or locking.

[0060] In some specific embodiments, as shown in Figures 1 to 7 As shown, the first abutting part 212 is the rear end part of the first locking member 21, and the second abutting part is a supporting leg 123 provided on the second locking member 12 and located on the rear side of the locking block 122. The length of the locking block 122 is preferably less than the length of the supporting leg 123, and the supporting leg 123 is provided with a bending part, so that the first locking member 21 abuts against the bending part. When the door body 2 is in the closed state, the rear end part of the first locking member 21 is located between the locking block 122 and the supporting leg 123. Specifically, a clamping groove is formed between the locking block 122 and the supporting leg 123. In the process of closing the door body 2, with the rotation of the second locking member 12, the locking block 122 is inserted into the locking hole 211. When the second locking member 12 is rotated to the locking position, the rear end part of the first locking member 21, specifically the rear side wall of the locking hole 211, is clamped in the clamping groove.

[0061] In some specific embodiments, as shown in Figure 2 and Figure 4As shown, the elastic member is a torsion spring 13, the body 1 is provided with a first torsion spring connecting portion 14, the second locking member 12 is provided with a second torsion spring connecting portion 121, and the two arms of the torsion spring 13 are respectively rotationally connected with the first torsion spring connecting portion 14 and the second torsion spring connecting portion 121; the second torsion spring connecting portion 121 and the locking block 122 are preferably respectively located on the opposite sides of the second locking member 12;

[0062] When the door body 2 is in the closed state, the torsion spring 13 swings to a first position and gives the second locking member 12 a positive force to keep the second locking member 12 in the locked position, that is, in the process of closing the door, the second locking member 12 will drive the torsion spring 13 to swing, and when the second locking member 12 rotates to the locked position, the elastic force of the torsion spring 13 makes the second locking member 12 have a tendency to continue to rotate positively, so that the second locking member 12 is locked with the first locking member 21, at this time the locking block 122 is inserted into the lock hole 211 to form a driving force to drive the door body 2 to continue to move towards the body 1, so that the door body 2 is kept in the closed state; when the door body 2 is in the open state, the torsion spring 13 swings to a second position and gives the second locking member 12 a reverse force to keep the second locking member 12 in the unlocked position. Specifically, the second locking member 12 can be combined with a limiting assembly to achieve, or the second locking member 12 abuts against the body when in the unlocked position and cannot continue to rotate reversely.

[0063] In some embodiments, as shown in Figure 2 、 Figure 4 and Figure 7 In order to limit the second locking member 12 to rotate positively or reversely between the locked position and the unlocked position, a limiting assembly is arranged between the second locking member 12 and the body 1.

[0064] Specifically, the limiting assembly includes an arc-shaped hole 125 arranged on the second locking member 12 and a limiting block 11 arranged on the body 1, and the limiting block 11 is located in the arc-shaped hole 125;

[0065] When the second locking member 12 rotates positively from the unlocked position to the locked position, the arc-shaped hole 125 rotates positively around the limiting block 11 to make the rear side wall of the arc-shaped hole 125 abut against the limiting block 11; so that the second locking member 12 cannot continue to rotate positively;

[0066] When the second locking member 12 reversely rotates from the unlocked position to the locked position, the arc-shaped hole 125 reversely rotates around the limiting block 11 to make the front side wall of the arc-shaped hole 125 abut against the limiting block 11; so that it cannot continue to rotate reversely.

[0067] In the embodiment, the second locking member 12 is arranged on the body 1 through a rotating shaft, or a set of the switch door limiting device in the embodiment is arranged on the left and right sides of the body 1.

[0068] Working principle:

[0069] As shown in Figures 1 to 4 When the door body 2 is closed, the user moves the door body 2 towards the body 1, the door body 2 abuts against the supporting leg 123 through the rear end of the first locking member 21, thereby driving the second locking member 12 to rotate forward, when rotating to the locking position, the locking block 122 is inserted into the lock hole 211, thereby locking the second locking member 12 and the first locking member 21, and the micro switch trigger part 124 triggers the micro switch 15; at this time, the second locking member 12 is kept in the locking position under the action of the elastic member, thereby keeping the door body 2 in the closed state;

[0070] When the door body 2 is opened, the door body 2 moves away from the body 1, because the first locking member 21 and the second locking member 12 are locked with each other, the door body 2 will drive the second locking member 12 to rotate reversely through the first locking member 21, in the process of rotating, the micro switch trigger part 124 is separated from the micro switch 15, when the second locking member 12 rotates to the unlocking position, the locking block 122 is separated from the lock hole 211, at this time, the second locking member 12 is kept in the unlocking position under the action of the elastic member.

[0071] The utility model is not limited to the above optional implementation, under the premise of not contradicting each other, any combination between schemes can be made; anyone can draw other various forms of products under the enlightenment of the utility model, but no matter any change in shape or structure, any technical scheme falling into the scope defined by the utility model claims falls into the protection scope of the utility model.
