The door lock device 10 of the present invention includes a door lock catch 100 and a door lock assembly 200, the door lock assembly 200 includes a lock case 210, a limiting member 220, a transmission member 230 and a control switch 240, the lock case 210 is used for being mounted on the inner container 22, the door lock catch 100 is used for being mounted on the door body 21, the limiting member 220 has a trigger portion 221 and a toggle portion 222, and the door lock catch 100 is detachably connected with the trigger portion 221 along the insertion hole 211 in an insertion manner; the limiting member 220 has a rotation fulcrum 223 rotatably connected with the lock case 210, a line which is parallel to the insertion direction of the insertion hole 211 and passes through the rotation fulcrum 223 is defined as a central line 11, and when the transmission member 230 is separated from the control switch 240, the triggering portion 221 and the toggle portion 222 are respectively arranged on two sides of the central line 11; when the door body 21 is closed, the door lock 100 is inserted along the insertion hole 211 and is inserted and matched with the trigger part 221, the door lock 100 drives the trigger part 221 to rotate while being inserted so as to drive the toggle part 222 to rotate by rotating the toggle transmission member 230, the transmission member 230 rotates under the driving of the toggle part 222 to be separated from the control switch 240 (as shown in fig. 4), at this time, the control switch 240 transmits the closing information of the door body 21 to the dishwasher 20 corresponding to the closing state of the door body 21, so that the dishwasher 20 can switch on the power supply of the motor to ensure the normal operation of the dishwasher 20; when the door body 21 is opened, the door latch 100 retreats from the insertion hole 211, the door latch 100 drives the trigger part 221 to rotate so as to drive the toggle part 222 and the transmission member 230 to rotate reversely according to the rotating direction of the door latch 100 when inserted, so that the transmission member 230 can rotate and abut against the control switch 240 (as shown in fig. 5 and fig. 6), at this time, the corresponding door body 21 is in a door opening state, the control switch 240 transmits the information that the door body 21 is opened to the dishwasher 20, so that the dishwasher 20 can disconnect the power supply of the motor, the motor of the dishwasher 20 is ensured to be in a power-off state, the condition that the washing water in the dishwasher 20 splashes outwards to cause a user to be wetted due to the work of the motor is avoided, and the safety of the dishwasher 20 is ensured;

when the door body 21 of the present application is opened, the transmission member 230 is separated from the control switch 240, and the trigger portion 221 and the toggle portion 222 of the limiting member 220 are respectively disposed at two sides of the center line 11, so that a connection line between the trigger portion 221 and the rotation fulcrum 223 is formed, and a lever structure is formed by the connection between the toggle portion 222 and the rotation fulcrum 223, when the door latch 100 exits from the insertion hole 211 and drives the trigger portion 221 to rotate, the toggle portion 222 can synchronously rotate and toggle the transmission member 230 to rotate through the lever structure on the limiting member 220, so that the transmission member 230 can synchronously rotate to abut against the control switch 240, and a signal that the control switch 240 quickly abuts against the transmission member 230 to the corresponding door body 21 to be opened is transmitted to the dishwasher 20, so that the dishwasher 20 can quickly disconnect the power supply of the motor, thereby avoiding a situation that after the motor of the dishwasher 20 is powered off slowly, the door body 21 is opened, the washing water inside the dishwasher 20 splashes outside to cause a user to be wetted, thereby realizing a quick response of the door lock device 10, and solving a problem of a slow response speed of an existing door lock device.

Referring to fig. 3 and 4, in an embodiment, the limiting member 220 includes a limiting support 224 rotatably installed in the accommodating cavity, and a triggering limiting rod 225 and a toggle limiting rod 226 disposed on the limiting support 224, the rotation fulcrum 223 is disposed on the limiting support 224, the triggering portion 221 is disposed at an end of the triggering limiting rod 225 far away from the limiting support 224, the toggle portion 222 is disposed at an end of the toggle limiting rod 226 far away from the limiting support 224, and when the transmission member 230 is disengaged from the control switch 240, the triggering limiting rod 225 and the toggle limiting rod 226 are disposed at two sides of the central line 11.

It can be understood that the triggering limiting rod 225 and the toggle limiting rod 226 are both bar-shaped rods, one end of the triggering limiting rod 225 is connected with the limiting support 224, and the triggering part 221 is arranged at the other end of the triggering limiting rod 225; one end of the toggle limiting rod 226 is connected with the limiting support 224, and the toggle part 222 is arranged at the other end of the toggle limiting rod 226. The trigger limiting rod 225 and the toggle limiting rod 226 are respectively arranged on two sides of the central line 11, the rotating fulcrum 223 is arranged on the limiting support 224, the trigger limiting rod 225 and the toggle limiting rod 226 are respectively arranged on two sides of the limiting support 224, the trigger limiting rod 225 and the toggle limiting rod 226 form a lever structure around the limiting support 224, when the trigger limiting rod 225 rotates, the toggle limiting rod 226 can synchronously rotate, and therefore the response speed of the door lock device 10 is improved.

Further, the length of the toggle limiting rod 226 is greater than the length of the toggle limiting rod 225, so that when the angle of the toggle limiting rod 225 rotating around the limiting support 224 is smaller, the angle of the toggle limiting rod 226 rotating around the limiting support 224 is larger, which is beneficial to increasing the angle of the toggle limiting rod 226 for toggling the transmission member 230 to enable the transmission member 230 to rapidly rotate to abut against the control switch 240 or to rapidly rotate to separate from the control switch 240, thereby increasing the corresponding speed of the door lock device 10.
