micro switches

110, 120, and 130 are reset.

In the interlocking structure, the locking assemblies 100 are all positioned in the electric appliance chamber 301 of the box body 300, the door hook 200 can be clamped with the buckle 140 of the locking assembly 100, so that the box body 300 is locked with the door body 400, when the door hook 200 extends into the electric appliance chamber 301 and is clamped with the buckle 140, the door hook 200 can enable the contact 111 of the first micro switch, the contact 121 of the second micro switch and the contact 131 of the third micro switch to be pressed, when the door hook 200 is separated from the buckle 140, the force is not applied to the door hook 200, the first micro switch 110, the second micro switch 120 and the third micro switch 130 are reset, whether the door body 400 is locked with the box body 300 can be judged by whether the contacts of the three micro switches are extruded by the door hook 200, because the three micro switches are all arranged in the electric appliance chamber 301, the distance between the electronic element in the electric appliance chamber 301 and the three micro switches is shortened, the length of the micro switches can be correspondingly shortened, and the material cost of the conducting wire can be saved, meanwhile, as the three micro switches are arranged in the electric appliance room 301, the leakage accidents caused by the fact that the insulating layers are burnt out when the three micro switches are arranged in other areas in the box body 300 can be prevented, and the safety of the equipment in use can be improved.

Alternatively, the number of micro-switches in the locking assembly 100 may be more than three.

Wherein, the box 300 generally has two spaces, the two spaces are respectively located at two sides of the cooking cavity 320, wherein the electric appliance chamber 301 is generally located at the right side of the cooking cavity 320, the electronic component is mainly located in the electric appliance chamber 301, the cooking cavity 320 is provided with an exhaust hole leading to the space at the left side of the cooking cavity 320, therefore, if food in the cooking cavity 320 catches fire, flame may enter the space at the left side of the cooking cavity 320 from the exhaust hole, at this time, if a microswitch is arranged in the space at the left side of the cooking cavity 320, a wire is arranged to connect the microswitch located in the space at the left side of the cooking cavity 320 with the electronic component in the electric appliance chamber 301, flame may burn the insulating layer of the wire, when the wire is electrified in subsequent use, the box 300 may be electrified to cause electric leakage, therefore, the microswitch is all arranged in the electric appliance chamber 301, the wire can be prevented from being burnt in the space at the left side of the cooking cavity 320, meanwhile, the conducting wire for connecting the microswitch and the electronic element is shorter, so that the material cost is lower.

Optionally, the three microswitches function differently. Optionally, the first microswitch 110 controls the on/off of secondary circuits such as a lamp, a fan motor, a turntable motor and the like; the second microswitch 120 is used for monitoring the opening and closing state of the door body 400; the third microswitch 130 controls the on-off of the microwave relay, and further controls the on-off of the magnetron. In other embodiments, three micro switches may also be used to monitor the opening and closing states of the door 400.

In one embodiment, as shown in fig. 1 to 4, the locking assembly 100 further includes a rotating arm 150, the rotating arm 150 is rotatably disposed in the electrical chamber 301, the rotating arm 150 has an initial position and an abutting position,

when the door hook 200 extends into the electric appliance chamber 301 and is clamped with the buckle 140, the door hook 200 pushes the rotating arm 150 to rotate from the initial position to the abutting position, so that the contact 111 of the first microswitch abuts against the rotating arm 150;

when the door hook 200 is separated from the catch 140, the contact 111 of the first micro switch is reset and pushes the rotating arm 150 to rotate from the abutting position to the initial position. The rotating arm 150 is located in the electric appliance chamber 301, when the door hook 200 extends into the electric appliance chamber 301, the door hook 200 contacts with the rotating arm 150 and pushes the rotating arm 150 to rotate until the door hook 200 is clamped with the buckle 140, the rotating arm 150 abuts against the contact 111 of the first micro switch, the first micro switch 110 and the rotating arm 150 are reset when the door hook 200 is separated from the buckle 140, the first micro switch 110 can be used for judging that the door body 400 is locked or separated with the box body 300 through the first micro switch 110, because the door hook 200 needs to simultaneously apply force to a plurality of micro switches, the micro switches have a certain volume, if the plurality of micro switches are simultaneously pressed by the door hook 200, the size of the door hook 200 needs to be set larger and is not beneficial to use, the rotating arm 150 is simultaneously matched with the door hook 200, the door hook 200 can simultaneously apply force to the plurality of micro switches in a smaller size, the structure is more reasonable, the rotating arm 150 is pushed to return to the initial position through the resetting process of the contact 111 of the first micro switch, the rotating arm 150 is returned to the initial position without a reset element, so that the number of parts can be reduced, the structure and the assembly are simplified, and the cost is saved.

In the process that door hook 200 stretches into electric appliance room 301 and is in clamping connection with buckle 140, door hook 200 pushes rotating arm 150 to contact with first micro switch 110 and second micro switch 120, so that first micro switch 110 and second micro switch 120 are powered on, and when door hook 200 breaks away from the bayonet and leaves electric appliance room 301, door hook 200 no longer applies force to rotating arm 150, first micro switch 110 and second micro switch 120 both reset, can push rotating arm 150 to return, because first micro switch 110 is closer to rotating part 151 than second micro switch 120, first micro switch 110 resets and can make rotating arm 150 rotate by a larger angle, ensure that second micro switch 120 can not contact with 150, can guarantee that the judgment of whether rotating arm 400 and box 300 are locked is more accurate.

The contact 111 of the first microswitch is always in contact with the rotating arm 150, but the force applied by the rotating arm 150 to the first microswitch 110 is not enough to press and electrify the first microswitch 110; or after the first microswitch 110 is reset, the rotating arm 150 can still rotate to the initial position by a certain angle under the action of gravity, so that the contact 111 of the first microswitch is not contacted with the rotating arm 150, and the judgment accuracy can be further improved.

In one embodiment, as shown in fig. 2, when the door hook 200 is engaged with the catch 140, the door hook 200 abuts against the contact 131 of the third microswitch. At this time, the three micro switches are respectively abutted by the door hook 200 or the rotating arm 150, which can prevent the door hook 200 or the rotating arm 150 from having a problem to cause a judgment error, wherein when the door hook 200 is clamped with the buckle 140, the door hook 200 is directly abutted with the contact 131 of the third micro switch, the rotating arm 150 rotates from the initial position to the abutting position under the pushing of the door hook 200 and is respectively abutted against the contact 111 of the first micro switch and the contact 121 of the second micro switch, when the door hook 200 is separated from the buckle 140, the door hook 200 is separated from the third micro switch 130 and leaves the electric appliance chamber 301, the third micro switch 130 is not stressed and resets, the rotating arm 150 is not pushed by the door hook 200 any more, and the first micro switch 110 and the second micro switch 120 reset and pushes the rotating arm 150 to be reset from the abutting position to the initial position.

When the door is opened, the door hook slides out of the switch bracket, the third microswitch 130 is firstly switched off, the second microswitch 120 is switched off, and finally the first microswitch 110 is switched off.

In other embodiments, the door hook 200 may also contact two of the microswitches, and the rotating arm 150 may contact the remaining one of the microswitches; or the rotating arm 150 is in contact with three microswitches.

In one embodiment, as shown in fig. 2 and 4, the other end of the rotating arm 150 is a terminal portion 152, and the positions of the terminal portions 152 during the rotation process of the rotating arm 150 are higher than the contacts 131 of the third micro switch. At this time, during the rotation of the rotating arm 150, the position of the terminal portion 152 is always higher than the contact 131 of the third micro switch, so that the terminal portion 152 can be prevented from mistakenly touching the contact 131 of the third micro switch during the rotation, and the third micro switch 130 can be ensured to be opened or closed only by the door hook 200.

In one embodiment, as shown in fig. 2, when the door hook 200 is engaged with the latch 140, the door hook 200, the latch 140 and the third micro switch 130 are located on one side of the rotating arm 150, and the first micro switch 110 and the second micro switch 120 are located on the other side of the rotating arm 150.

At this time, the structure of the rotating arm 150 can facilitate the arrangement of the first and second

micro switches

110 and 120, and ensure that the rotating arm 150 can simultaneously press the contacts 121 of the first and second

micro switches

110 and 120.

Alternatively, the length of the first flap 153 is smaller than the length of the second flap 154, and the displacement of the second flap 154 when rotated is larger than the displacement of the first flap 153, ensuring that the second microswitch 120 can be separated from the rotating arm 150 earlier.
