[0013] The present application proposes a door lock device and a dishwasher including the door lock device. The door lock device of the present application can improve the drying effect of the dishwasher and reduce the energy consumption of the dishwasher.

[0014] As shown in FIG. 1 to FIG. 5, in an embodiment of a door lock device 10 of the present application, the door lock device 10 is applied to a dishwasher. The door lock device 10 is provided between a door 11 and a tank 12 of the dishwasher. The door lock device 10 includes a door latch 100 and a door lock assembly 200. The door latch 100 is installed at the door 11. The door lock assembly 200 includes a lock housing 210, a pusher 220 and a drive assembly 230. The lock housing 210 is installed at the tank 12. The lock housing 210 is provided with an accommodation cavity and a socket 211 for the door latch 100 to be inserted or retracted. The pusher 220 is rotatably installed in the accommodation cavity. The door latch 100 is detachably connected to the pusher 220 along the socket 211. The drive assembly 230 is configured to drive the pusher 220 to rotate. The pusher 220, upon rotation, drives the door latch 100 to retract from the accommodation cavity along the socket 211 so as to drive the door 11 of the dishwasher to open.

[0015] It can be understood that the drive assembly 230 can be provided in the lock housing 210. There can be various options for the drive assembly 230, such as but not limited to: a cylinder assembly, a wax motor assembly, or a motor assembly, etc., as long as the drive assembly 230 is capable of driving the pusher 220 to rotate and the pusher 220 can push the door latch 100 upon rotation. The door latch 100 is installed at the door 11. The door latch 100 is arranged corresponding to the socket 211 on the lock housing 210. When the door latch 100 is inserted into the accommodation cavity along the socket 211, the door 11 is in contact with the tank 12, the door 11 is closed. When the door latch 100 is pushed outward along the socket 211 by the pusher 220, the door 11 is opened at this time.

[0016] After the dishwasher finishes washing the tableware inside the tank 12, the tableware needs to be dried. During a drying stage, the dishwasher can use the door lock device 10 of the present application to automatically open the door 11, and the drive assembly 230 of the door lock assembly 200 can be electrically connected to an electronic control device in the tank 12. The pusher 220 is driven to rotate by the drive assembly 230. When the pusher 220 rotates, it pushes the door latch 100 to retract from the accommodation cavity along the socket 211 to drive the door 11 to open. The door 11 can be opened to a certain angle or a preset distance to allow a certain degree of air convection between the tank 12 of the dishwasher and the outside. Therefore, when the dishwasher is in the drying stage, the door lock device 10 of the present application can automatically open the door 11 of the dishwasher, so that the high-temperature moisture in the tank 12 of the dishwasher can be quickly discharged to the outside, to improve the drying efficiency of tableware. Consequently, the temperature in a rinsing stage can be reduced to achieve the purpose of reducing the energy consumption of the dishwasher, and the safety hazards of high-temperature water spraying when the door is opened during operation can be avoided, while achieving better drying effects.

[0017] The door lock device 10 of the present application includes a door latch 100 and a door lock assembly 200. The door latch 100 is installed at the door 11. The door lock assembly 200 includes a lock housing 210, a pusher 220 and a drive assembly 230. The lock housing 210 is installed at the tank 12. The lock housing 210 is provided with an accommodation cavity and a socket 211 for the door latch 100 to be inserted or retracted. The pusher 220 is rotatably installed in the accommodation cavity. The door latch 100 is detachably connected to the pusher 220 along the socket 211. The drive assembly 230 is configured to drive the pusher 220 to rotate. The pusher 220, upon rotation, drives the door latch 100 to retract from the accommodation cavity along the socket 211 so as to drive the door 11 of the dishwasher to open. In this way, the door lock device 10 of the present application can automatically open the door 11 of the dishwasher, so that the dishwasher can discharge the hot and humid steam in the tank 12 during the drying stage. This helps the dishwasher achieve a better drying effect at a lower washing temperature. The lower washing temperature makes the dishwasher consume less power, thus reducing the energy consumption of the dishwasher. Therefore, the door lock device 10 of the present application can improve the drying effect of the dishwasher and reduce the energy consumption of the dishwasher.

[0018] As shown in FIG. 2 to FIG. 5, in an embodiment, the door lock assembly 200 further includes a transmission assembly 240. The transmission assembly 240 is rotatably installed in the accommodation cavity. One end of the transmission assembly 240 is connected to the pusher 220. The drive assembly 230 is configured to drive the transmission assembly 240 to rotate, to drive the pusher 220 to rotate and push the door latch 100 to retract from the accommodation cavity along the socket 211.

[0019] It can be understood that the drive assembly 230 is configured to drive the transmission assembly 240 to rotate, that is, the drive assembly 230 only drives the transmission assembly 240 to rotate when it is necessary to open the door 11. A drive end of the drive assembly 230 can be connected to the transmission assembly 240, or abutted against the transmission assembly 240, or spaced apart from the transmission assembly 240 when the drive assembly 230 does not need to drive the transmission assembly 240 to rotate. It is sufficient only if the drive assembly 230 can drive the transmission assembly 240 to rotate when needed. In other words, when the drive assembly 230 does not need to drive the transmission assembly 240 to rotate, the connection relationship between the drive assembly 230 and the transmission assembly 240 is not limited. This allows the installation position of the drive assembly 230 to be flexible, and the drive assembly 230 can be arranged according to the specific structure of the lock housing 210. The installation position of the drive assembly 230 is more flexible, and the structure of the door lock assembly 200 can be optimized.

[0020] Furthermore, the rotation of the transmission assembly 240 drives the pusher 220 to rotate, allowing the pusher 220 to rotate stably, and the transmission assembly 240 also has the function of limiting the position of the pusher 220. When the transmission assembly 240 is not rotating, it is connected to the pusher 220 and restricts the rotation of the pusher 220, to ensure the stability of the pusher 220 installed in the lock housing 210.

[0021] As shown in FIG. 2 to FIG. 4, in an embodiment, the transmission assembly 240 is provided between the drive assembly 230 and the pusher 220. When the drive assembly 230 drives the transmission assembly 240 to rotate, the rotation direction of the transmission assembly 240 is opposite to the direction in which the transmission assembly 240 drives the pusher 220 to rotate.

[0022] It can be understood that, as shown in FIG. 3 and FIG. 4, the drive assembly 230 is configured to drive the transmission assembly 240 to rotate counterclockwise about its rotation axis. When the transmission assembly 240 rotates counterclockwise, it can drive the pusher 220 to rotate clockwise about its rotation axis. The pusher 220 is provided at one side of the door latch 100, allowing the pusher 220 to push the door latch 100 to retract from the accommodation cavity along the socket 211. During this process, the rotation direction of the transmission assembly 240 is opposite to that of the pusher 220. The transmission assembly 240 rotates and drives the pusher 220 to rotate, ensuring a smooth and stable rotation of the pusher 220. In addition, the rotation area of the transmission assembly 240 partially overlaps with the rotation area of the pusher 220, resulting in a compact arrangement of the transmission assembly 240 and the pusher 220, which is beneficial to reducing the size of the door lock assembly 200. In other embodiments, the drive assembly 230 can also drive the transmission assembly 240 to rotate clockwise about its rotation axis. When the transmission assembly 240 rotates clockwise, it can drive the pusher 220 to rotate counterclockwise about its rotation axis, which is also conducive to improving the rotation stability of the pusher 220. In addition, the rotation area of the transmission assembly 240 partially overlaps with the rotation area of the pusher 220, resulting in a compact arrangement of the transmission assembly 240 and the pusher 220, which is beneficial to reducing the size of the door lock assembly 200.

[0023] As shown in FIG. 4 and FIG. 5, in an embodiment, the transmission assembly 240 includes a transmission member 241 and a torsion spring 242. A first torsion leg of the torsion spring 242 is connected to the pusher 220, and a second twist leg of the torsion spring 242 is connected to the lock housing 210. One end of the transmission member 241 is connected to the torsion spring 242, and the other end of the transmission member 241 is abutted against the drive assembly 230, so that the drive assembly 230 can drive the transmission member 241 and the torsion spring 242 to rotate synchronously, thereby driving the pusher 220 to rotate.

[0024] It can be understood that the first torsion leg of the torsion spring 242 can drive the pusher 220 to rotate, and the second torsion leg of the torsion spring 242 rotates around the lock housing 210. The transmission member 241 is connected to the torsion spring 242, allowing the transmission member 241 to rotate synchronously with the torsion spring 242. When it is necessary to open the door 11, the drive assembly 230 first is abutted against the transmission member 241, and then applies a thrust to the transmission member 241 to drive the transmission member 241 to rotate. As the transmission member 241 rotates, it drives the torsion spring 242 to rotate synchronously. The first torsion leg of the torsion spring 242 drives the transmission member 241 to rotate, and the transmission member 241 rotates and pushes the door latch 100 to move out of the accommodation cavity in the socket 211, thereby automatically opening the door 11.

[0025] Further, during the rotation of the torsion spring 242, the first torsion leg approaches the second torsion leg, an angle between the first torsion leg and the second torsion leg becomes smaller, and the torsion spring 242 is compressed until the torsion spring 242 is compressed to the maximum compression state. If the drive assembly 230 continues to apply the drive force to the transmission member 241, the elastic force of the torsion spring 242 will be released. At this time, the drive assembly 230 stops applying the drive force, but the first torsion leg of the torsion spring 242 continues to pull the pusher 220, causing the pusher 220 to rotate. The pusher 220 continues to rotate, which will continue to push the door latch 100 to move out of the accommodation cavity in the socket 211, to automatically open the door 11. During this process, the elastic force of the torsion spring 242 is released, which is equivalent to assisting the drive assembly 230 in applying the drive force to the pusher 220. This ensures a smoother and faster rotation of the pusher 220, allowing the door 11 to be opened quickly, thereby improving the reliability of the door lock device 10.

[0026] As shown in FIG, 5, in an embodiment, the transmission member 241 includes a rotary base 243, and a plug-in portion 244 and a match portion 245 provided at the rotary base 243. An installation column 212 is provided at the lock housing 210. The rotary base 243 is rotatably provided at the installation column 212. A collar is provided between the first torsion leg and the second torsion leg of the torsion spring 242, and the plug-in portion 244 is inserted into the collar. The drive assembly 230 is configured to drive the match portion 245 to rotate, and the second torsion leg of the torsion spring 242 is connected to the installation column 212.

[0027] It can be understood that a rotation hole is provided at the rotary base 243, and the rotary base 243 is rotatably connected to the installation column 212 through the rotation hole. The plug-in portion 244 can be provided at one end of the rotary base 243, and the match portion 245 is spaced apart from the plug-in portion 244, for example, the match portion 245 is provided at the other end of the rotary base 243. The plug-in portion 244 includes a connection section and a plug-in column. The connection section connects the plug-in column to the rotary base 243. The plug-in column is inserted into the collar of the torsion spring 242. The plug-in column can be interference-fit or clearance-fit with the collar, which is not specifically limited here, as long as the transmission member 241 can rotate synchronously with the torsion spring 242. Moreover, the second torsion leg of the torsion spring 242 is connected to the installation column 212, that is, the second torsion leg of the torsion spring 242 is connected to the rotation center of the transmission member 241. This ensures the synchronous rotation of the transmission member 241 and the torsion spring 242, improving the stability of the door lock assembly 200. When it is necessary to drive the transmission member 241 to rotate, the drive assembly 230 is abutted against the match portion 245 and provides the drive force to the match portion 245. The drive assembly 230 can be spaced apart from or abut against the match portion 245 at an initial position, or can be connected to the match portion 245, which is not specifically limited here.

[0028] As shown in FIG. 6 to FIG. 8, in an embodiment, the door lock assembly 200 further includes a first connection rod 250. One end of the first connection rod 250 is rotatably connected to the drive assembly 230, and the other end of the first connection rod 250 is rotatably connected to the transmission member 241. The drive assembly 230 is configured to drive the first connection rod 250 to move and drive the transmission member 241 to rotate, to allow the torsion spring 242 to drive the pusher 220 to rotate.

[0029] It can be understood that the drive assembly 230 is connected to the transmission member 241 through the first connection rod 250. Two opposite ends of the first connection rod 250 are rotatably connected to the drive assembly 230 and the transmission member 241 respectively. This allows the first connection rod 250 to rotate relative to the transmission member 241 when driving the transmission member 241 to rotate, reducing the friction between the transmission member 241 and the first connection rod 250. Consequently, the collision wear between the transmission member 241 and the drive assembly 230 can be alleviated, increasing the service life of the door lock assembly 200.

[0030] Furthermore, the first connection rod 250 can be rotatably connected to the drive end of the drive assembly 230 through a connection member, for example, the first connection rod 250 is connected to the drive end of the drive assembly 230 through a bolt structure, etc., which are not specifically limited here.

[0031] In an embodiment, an end of the first connection rod 250 adjacent to the transmission member 241 is provided with a first groove (not shown), and the match portion 245 of the transmission member 241 is provided with a first protruding column 246 adapted to the first groove. The first protruding column 246 is detachably and rotatably connected to the first groove. In this way, when the drive assembly 230 drives the first connection rod 250 to move toward the transmission member 241, the first groove on the first connection rod 250 moves toward the first protruding column 246 of the match portion 245 until the first protruding column 246 is engaged in the first groove. The drive assembly 230 continues to apply the drive force, and the first connection rod 250 applies the thrust to the first protruding column 246 through the first groove, causing the transmission member 241 to rotate around the installation column 212 and driving the torsion spring 242 to rotate synchronously. At this time, the first protruding column 246 rotates in the first groove, so that the friction force between the first connection rod 250 and the match portion 245 of the transmission member 241 is small, and the collision wear between the first connection rod 250 and the transmission member 241 is less, which is beneficial to increasing the service life of the door lock assembly 200. When the drive assembly 230 drives the first connection rod 250 to move away from the transmission member 241, the first groove on the first connection rod 250 moves away from the first protruding column 246 of the match portion 245 until the first protruding column 246 is located outside the first groove, so that the first protruding column 246 is separated from the first groove, achieving a detachable rotational connection between the first protruding column 246 and the first groove.

[0032] In the embodiment of FIG. 13 to FIG. 15 and the embodiment of FIG. 16 to FIG. 18, the door lock assembly 200 further includes a second connection rod 260, and the second connection rod 260 has a first end and a second end opposite to each other along its length direction. The first end is rotatably connected to the lock housing 210, and the drive assembly 230 is configured to drive the second connection rod 260 to rotate around the first end, to allow the second end to drive the transmission member 241 to rotate.

[0033] It can be understood that the first end is provided at the side of the second end away from the transmission member 241, the first end is rotatably provided at the lock housing 210, and the first end is provided with a rotation hole. A rotate column is provided at the lock housing 210. The first end is rotatably connected to the rotation column through the rotation hole. The drive assembly 230 pushes the second connection rod 260 to rotate around the first end, and the second end of the second connection rod 260 drives the transmission member 241 to rotate while rotating, that is, the second connection rod 260 can rotate in the lock housing 210 stably, and can synchronously drive the transmission member 241 to rotate stably, which is beneficial to improving the rotation stability of the transmission member 241.

[0034] As shown in FIG. 13 to FIG. 15, in an embodiment, a hook groove 261 is provided at the second end, and a second protruding column 247 is provided at the match portion 245 of the transmission member 241. The side of the hook groove 261 facing the second protruding column 247 is open, and the hook groove 261 is detachably and rotatably connected to the second protruding column 247.

[0035] It can be understood that the hook groove 261 is configured to hook the second protruding column 247 so as to drive the match portion 245 to rotate. When the drive assembly 230 drives the second connection rod 260 to rotate to abut against the match portion 245, the second protruding column 247 slides into the hook groove 261 along the opening of the hook groove 261. The second connection rod 260 continues to rotate under the drive force of the drive assembly 230. The hook groove 261 continues to exert the thrust on the second protruding column 247. The second protruding column 247 can rotate within the hook groove 261 as the transmission member 241 rotates, which is beneficial to reducing the friction between the second connection rod 260 and the transmission member 241. The transmission member 241 rotates under the driving of the second connection rod 260, and the torsion spring 242 rotates synchronously with the transmission member 241 until the torsion spring 242 is compressed to the maximum compression state. Then, under the elastic force of the torsion spring 242, the torsion spring 242 drives the transmission member 241 to continue to rotate. The rotation direction of the second connection rod 260 is opposite to that of the transmission member 241. When the transmission member 241 rotates to a certain angle, the second protruding column 247 can move from the inside of the hook groove 261 to the outside of the hook groove 261, so that the second protruding column 247 is separated from the hook groove 261. This allows the transmission member 241 to rotate smoothly in the lock housing 210, improving the smoothness of the rotation of the transmission member 241.

[0036] As shown in FIG. 16 to FIG. 18, in an embodiment, the drive assembly 230 has a drive end, and the second connection rod 260 is provided with an abut portion 262. The drive end of the drive assembly 230 is rotatably connected to the abut portion 262 of the second connection rod 260. The abut portion 262 is provided with an abut groove, and a wall of the abut groove is configured as a smooth arc surface. By providing the abut portion 262, the drive end of the drive assembly 230 can be rotatably connected to the second connection rod 260 stably, which is beneficial to reducing the friction between the drive end of the drive assembly 230 and the second connection rod 260.

[0037] As shown in FIG. 13 to FIG. 15, in an embodiment, a slide groove 263 is provided at one of the drive end of the drive assembly 230 and the second connection rod 260, and a drive column 231 is provided at the other of the drive end of the drive assembly 230 and the second connection rod 260. The drive column 231 is slidably provided in the slide groove 263 along a length direction of the slide groove 263, and the drive column 231 is rotatably provided in the slide groove 263.

[0038] For convenience of illustration, an example in which the slide groove 263 is provided at the second connection rod 260 and the drive end of the drive assembly 230 is provided with the drive column 231 is described. The length direction of the slide groove 263 extends along the length direction of the second connection rod 260. The drive column 231 is engaged in the slide groove 263. When the drive assembly 230 applies the thrust to the second connection rod 260, the drive column 231 can slide in the slide groove 263 along its length direction, and the drive column 231 pushes the second connection rod 260 to rotate, allowing the drive column 231 to rotate in the slide groove 263. In other words, the drive column 231 can not only slide but also rotate in the slide groove 263. In this way, the friction between the second connection rod 260 and the drive end of the drive assembly 230 is small, ensuring the smooth rotation of the second connection rod 260 while reducing the collision wear between the second connection rod 260 and the drive assembly 230, which is beneficial to increasing the service life of the door lock assembly 200.

[0039] As shown in FIG. 16 to FIG. 18, in an embodiment, the door lock assembly 200 further includes a rebound assembly 270. The rebound assembly 270 is provided at the side of the first end away from the second end and connected to the first end. The drive assembly 230 is configured to drive the second connection rod 260 to rotate around the first end and drive the rebound assembly 270 to move. The rebound assembly 270 is configured to provide power to the second connection rod 260, to rotate and return the second connection rod 260 to the initial position.

[0040] It can be understood that when the drive assembly 230 drives the second connection rod 260 to rotate, the second connection rod 260 drives the rebound assembly 270 to move so as to squeeze the rebound assembly 270. The rebound assembly 270 has elasticity, and can provide power to the second connection rod 260 to return to the initial position when the drive assembly 230 stops drive force. This arrangement enables the second connection rod 260 to quickly return to the initial position, to prevent the second connection rod 260 from hindering the transmission member 241 when the transmission member 241 is reset, to allow the transmission member 241 and the pusher 220 to reset quickly. The rapid reset of the pusher 220 enables the door 11 to be closed quickly, improving smoothness of the door 11 closing of the dishwasher.

[0041] In an embodiment, the rebound assembly 270 includes a pressure rod 271 and a rebound member 272. The pressure rod 271 is provided between the second connection rod 260 and the rebound member 272. One end of the pressure rod 271 is connected to the first end, and the other end of the pressure rod 271 is abutted against the rebound member 272. The drive assembly 230 is configured to drive the second connection rod 260 to rotate around the first end and drive the pressure rod 271 to rotate synchronously, to allow the pressure rod 271 to squeeze the rebound member 272. The rebound member 272 is configured to provide a rebound force to the pressure rod 271.

[0042] It can be understood that the pressure rod 271 is fixedly connected to the first end of the second connection rod 260, and the rotation direction of the pressure rod 271 is the same as that of the second connection rod 260. When the drive assembly 230 drives the second connection rod 260 to rotate, the second connection rod 260 drives the pressure rod 271 to rotate synchronously, and the end of the pressure rod 271 away from the first end rotates toward the rebound member 272 to squeeze the rebound member 272. In an embodiment, the rebound member 272 includes a push rod 273 and a spring 274. A positioning groove is provided at the lock housing 210. The spring 274 is provided in the positioning groove. The push rod 273 is inserted into the spring 274. One end of the push rod 273 is abutted against the pressure rod 271, and the length of the push rod 273 is smaller than the length of the spring 274. In this way, the pressure rod 271 can squeeze the spring 274 through the push rod 273 when rotating. The spring 274 is squeezed and has elastic force. When the drive assembly 230 stops providing the drive force to the second connection rod 260, the elastic force of the spring 274 is released, so that the push rod 273 pushes pressure rod 271 to rotate, thereby driving the second connection rod 260 to return to the initial position. In other embodiments, the rebound member 272 can also be of other structures, such as elastic support bars, etc., which are not limited here. The rebound member 272 is provided to provide a rebound force to the pressure rod 271, allowing the second connection rod 260 to return to the initial position when the drive assembly 230 stops providing the drive force, so that the door 11 can be closed smoothly and it is convenient for the next time to quickly open the door 11.

[0043] As shown in FIG. 2 to FIG. 5, in an embodiment, the drive assembly 230 includes a driver 232 and a drive rod 233. The driver 232 is configured to drive the drive rod 233 to move, to allow the drive rod 233 to drive the transmission member 241 to rotate. The drive rod 233 has a drive end, and the drive end is abutted against the match portion 245 of the transmission member 241.

[0044] It can be understood that in an embodiment, when the drive end of the drive assembly 230 drives the transmission member 241 to rotate, the drive end is abutted against the transmission member 241 to provide the drive force to the transmission member 241. When the drive assembly 230 provides no drive force to the transmission member 241 at its initial position, the drive end of the drive assembly 230 can be spaced apart from the transmission member 241. In other words, when the door 11 is open, the drive end of the drive assembly 230 is spaced apart from the transmission member 241. When the door 11 is closed, the drive end of the drive assembly 230 abut against the transmission member 241. Such an arrangement ensures that there is no resistance when manually closing the door, making the operation easier and enabling the door to be closed quickly.

[0045] As shown in FIG. 9 to FIG. 12, in an embodiment, the drive assembly 230 includes a driver 232 and a drive rod 233. The driver 232 is configured to drive the drive rod 233 to move, allowing the drive rod 233 to drive the transmission member 241 to rotate. The drive rod 233 has a drive end, and the drive end is provided with a second groove 234. A third protruding column 248 matching the second groove 234 is provided at the match portion 245 of the transmission member 241. The third protruding column 248 is rotatably provided in the second groove 234.

[0046] It can be understood that the side of the second groove 234 facing the third protruding column 248 is open. When the driver 232 drives the drive rod 233 to move toward the match portion 245 of the transmission member 241, the second groove 234 on the drive rod 233 moves toward the third protruding column 248 of the match portion 245 until the third protruding column 248 is engaged in the second groove 234. The driver 232 continues to apply the drive force, and the drive rod 233 applies the thrust to the third protruding column 248 through the second groove 234, to allow the transmission member 241 to rotate around the installation column 212 and drive the torsion spring 242 to rotate synchronously. At this time, the third protruding column 248 can rotate within the second groove 234, so that the friction between the transmission member 241 and the drive rod 233 is small, and the collision wear between the transmission member 241 and the drive rod 233 is less, which is beneficial to increasing the service life of the door lock assembly 200.

[0047] As shown in FIG. 19 to FIG. 21, in an embodiment, the drive assembly 230 includes a driver 232 and a drive rod 233. The driver 232 is configured to drive the drive rod 233 to move, to allow the drive rod 233 to drive the transmission member 241 to rotate. The drive rod 233 has a drive end, and the drive end is provided with a rack 235. A gear 249 adapted to the rack 235 is provided at the match portion 245 of the transmission member 241. The gear 249 meshes with the rack 235.

[0048] It can be understood that the drive rod 233 and the transmission rod are connected by meshing the gear 249 and the rack 235, so that when the drive rod 233 drives the transmission member 241 to rotate, the drive rod 233 is not easily disengaged from the transmission rod. In this way, the drive rod 233 can stably drive the transmission rod to rotate, thereby improving the reliability of the door lock assembly 200.

[0049] In the above embodiments, the driver 232 is a wax motor. The wax motor is electrically connected to the electronic control device in the tank 12 of the dishwasher. The electronic control device can control the operation of the wax motor.

[0050] In the embodiments of FIG. 2 to FIG. 4, the embodiments of FIG. 6 to FIG. 8, the embodiments of FIG. 9 to FIG. 12 and the embodiments of FIG. 19 to FIG. 21, the door lock assembly 200 further includes a toggle member 280 and a control switch 290. The toggle member 280 is rotatably provided in the accommodation cavity. When the door latch 100 is inserted into the pusher 220, it drives the pusher 220 to rotate and drives the toggle member 280 to rotate. This allows the toggle member 280 to have a disengaged position away from the control switch 290 and an engaged position abutting against the control switch 290. The dishwasher includes a motor. When the toggle member 280 is abutted against the control switch 290, the door 11 of the dishwasher is open and the power supply of the motor is turned off. When the toggle member 280 is disengaged from the control switch 290, the door 11 of the dishwasher is closed and the power supply of the motor is turned on.

[0051] It can be understood that a contact switch can be provided at the control switch 290. When the toggle member 280, driven by the pusher 220, rotates to engage or disengage with the control switch 290, the toggle member 280 is engaged or disengaged with the contact switch on the control switch 290. The control switch 290 can be a micro switch.

[0052] Further, the control switch 290 can be electrically connected to the control circuit board of the dishwasher, and the control switch 290 can feed back information that the door 11 is opened or closed to the control circuit board. Specifically, when the door 11 is opened, the toggle member 280 is abutted against the control switch 290, the control switch 290 feeds back information that the door 11 is opened to the control circuit board, and the control circuit board controls the power supply of the motor of the dishwasher to be cut off. This can ensure the safety and reliability when the door 11 of the dishwasher is opened. At this time, the control circuit board can also cut off power to other parts of the dishwasher, not limited to the motor. It is sufficient only if the safety of using the dishwasher can be ensured. When the door 11 is closed, the toggle member 280 is disengaged from the control switch 290, the control switch 290 feeds back information that the door 11 is closed to the control circuit board, and the control circuit board turns on the power of the motor of the dishwasher, to ensure the normal operation of the dishwasher.

[0053] Further, when the door latch 100 is inserted into the socket 211 and engages with the pusher 220, the door 11 is closed. The door latch 100 drives the pusher 220 to rotate while being inserted, and the pusher 220 drives the transmission member 241 to rotate. The toggle member 280 rotates to the disengaged position under the push of the pusher 220. At this time, the toggle member 280 is disengaged from the control switch 290, the door 11 is in a closed state, and the control switch 290 transmits the closing information of the door 11 to the dishwasher, so that the dishwasher can turn on the power of the motor to ensure the normal operation of the dishwasher. When the door latch 100 retracts from the socket 211, the door 11 is opened, the door latch 100 drives the pusher 220 to rotate, and the pusher 220 no longer exerts force on the toggle member 280. The toggle member 280 rotates from the disengaged position to the engaged position to abut against the control switch 290. At this time, the door 11 is in an open state, and the control switch 290 transmits the information that the door 11 is opened to the dishwasher, so that the dishwasher can turn off the power supply of the motor, ensuring that the motor of the dishwasher is in a power-off state and avoiding the situation that the washing water inside the dishwasher is splashed outside due to operation of the motor and causes the user to get wet, thereby ensuring the safety of the dishwasher.

[0054] In the embodiments of FIG. 6 to FIG. 8, the embodiments of FIG. 9 to FIG. 12 and the embodiments of FIG. 19 to FIG. 21, a clearance slot 281 is provided at the toggle member 280, and a push portion 221 is provided at the pusher 220. In the disengaged position, the push portion 221 is provided outside the clearance slot 281 and engages with the toggle member 280, and the power of the motor is turned on. In the engaged position, the pusher 221 is provided in the clearance slot 281, and the power of the motor is turned off.

[0055] It can be understood that the specific structure of the clearance slot 281 is not limited, as long as it can accommodate the push portion 221. When the push portion 221 is provided in the clearance slot 281, the wall of the clearance slot 281 is spaced apart from the push portion 221, so that the push portion 221 no longer exerts force on the toggle member 280. In other words, the clearance slot 281 is configured to avoid the push portion 221, so that the push portion 221 does not engage with the toggle member 280, and the push portion 221 no longer restricts the toggle member 280. At this time, the toggle member 280 can rotate to the engaged position to abut with the control switch 290. This allows the dishwasher to control the power of the motor to be turned off, thereby ensuring the safety of the dishwasher when the door 11 is opened. In addition, by providing the clearance slot 281, when the door 11 is closed, the door latch 100 is inserted into the socket 211 and drives the pusher 220 to rotate. The pusher 220 needs to rotate from the inside of the clearance slot 281 to the outside of the clearance slot 281, to engage with the toggle member 280, thus extending the rotation distance of the pusher 220, ensuring that the door latch 100 is inserted into a deeper depth, and the power of the motor is restored when the door 11 is closed, thereby improving the safety of the dishwasher.

[0056] In an embodiment, by providing the clearance slot 281, when the door 11 is opened, the door latch 100 drives the pusher 220 to rotate, and the push portion 221 of the pusher 220 can rotate from outside the clearance slot 281 to inside the clearance slot 281. When the push portion 221 is outside the clearance slot 281, it is abutted against the toggle member 280, and the toggle member 280 is in the disengaged position. When the push portion 221 rotates into the clearance slot 281, it does not contact the clearance slot 281, and the toggle member 280 is in the engaged position. That is, by providing the clearance slot 281, the push portion 221 can quickly change the contact state with the toggle member 280, and the toggle member 280 can quickly rotate from the disengaged position to the engaged position, which can quickly turn off the power supply of the motor, avoiding the situation where the washing water inside the dishwasher splashes out after the door 11 is opened due to the slow power-off speed of the dishwasher motor, causing the user to get wet. This achieves a quick response of the door lock device 10 and is conducive to improving slow response speed of the existing door lock device 10.

[0057] As shown in FIG. 6 to FIG. 8, in an embodiment, the toggle member 280 includes a toggle support 282 and a first toggle rod 283. The toggle support 282 is rotatably installed in the accommodation cavity. One end of the first toggle rod 283 is connected to the toggle support 282. The first toggle rod 283 has an abut portion for abutting against the pushing portion 221. The clearance slot 281 is provided between the abut portion and the toggle support 282.

[0058] It can be understood that the pusher 220 drives the toggle member 280 to rotate during the rotation, and the push portion 221 is abutted against the abut portion on the toggle member 280, allowing the push portion 221 of the pusher 220 to exert force on the toggle member 280. The clearance slot 281 is provided between the abut portion and the toggle support 282. The distance between the clearance slot 281 and the abut portion is smaller than the distance between the clearance slot 281 and the toggle support 282. When the door 11 is opened, and the door latch 100 drives the push portion 221 of the pusher 220 to rotate, the push portion 221 can quickly rotate from the position abutting against the abut portion to the inside of the clearance slot 281. That is to say, a relatively small rotation angle of the push portion 221is sufficient for the toggle member 280 to abut against the control switch 290. A shorter response stroke of the push portion 221 when the door 11 is opened results in a shorter time for the toggle member 280 to abut against the control switch 290, thereby enabling the control switch 290 to quickly trigger and transmit the signal indicating that the door 11 is opened, shortening the time for the dishwasher to turn off the power supply of the motor, and improving the response speed of the door lock device 10.

[0059] In an embodiment, the extension of a line connecting the position of the control switch 290 and the position of the first toggle rod 283 passes through the socket 211. Such an arrangement results in a compact arrangement of the control switch 290, the first toggle rod 283, and the door latch 100 in the lock housing 210, which is conducive to improving the utilization of the internal space of the door lock device 10 and further reducing the volume of the door lock device 10.

[0060] In an embodiment, the toggle member 280 further includes a second toggle rod 284. One end of the second toggle rod 284 is connected to the toggle support 282. The door lock assembly 200 further includes an elastic member, and the second toggle rod 284 is provided between the first toggle rod 283 and the elastic member. The second toggle rod 284 is abutted against the elastic member, and can rotate and abut against the control switch 290 under the elastic force of the elastic member. The first toggle rod 283 can drive the second toggle rod 284 to rotate and disengage from the control switch 290 under the actuation of the push portion 221.

[0061] It can be understood that the elastic member can be a spring. A first positioning protrusion is provided at the second toggle rod 284, a positioning plate is provided in the accommodating groove, and a second positioning protrusion is provided at the positioning plate. One end of the elastic member is abutted against the second toggle rod 284, and the first positioning protrusion is inserted into the elastic member. The other end of the elastic member is abutted against the positioning plate, and the second positioning protrusion is inserted into the elastic member. Such an arrangement enables the elastic member to be stably installed between the positioning plate and the second toggle rod 284, ensuring the stability of the installation of the elastic member and the cooperation with the second toggle rod 284.

[0062] Further, the second toggle rod 284 is provided between the first toggle rod 283 and the elastic member. When the smaller rotation angle of the push portion 221 is sufficient for the toggle member 280 to abut against the control switch 290, the second toggle rod 284 also rotates to a smaller angle to contact the control switch 290 under the elastic force of the elastic member. The second toggle rod 284 has a shorter rotation response stroke, and the second toggle rod 284 has less time to trigger the control switch 290, that is, the toggle member 280 has less time to trigger the control switch 290. As a result, the control switch 290 can quickly trigger and transmit the signal indicating that the door 11 is opened, thereby shortening the time for the dishwasher to cut off the power supply of the motor, and improving the response speed of the door lock device 10.

[0063] In an embodiment, the first toggle rod 283 and the second toggle rod 284 form an angle α, where 20°≤α≤160°. Such an arrangement is beneficial to reducing the length of the toggle member 280. The angle α can be 20°, 60°, 90°, 100°, 120°, 160°, etc. In this embodiment, the angle α is 90°, allowing the second toggle rod 284 to be adjacent to the side plate of the lock housing 210, and the first toggle rod 283 to be adjacent to the middle of the accommodation cavity. This results in a compact arrangement of the first toggle rod 283 and the second toggle rod 284 in the accommodation cavity, occupying a smaller longitudinal space. Consequently, the space utilization in the accommodation cavity is improved and the length of the lock housing 210 is reduced.

[0064] In an embodiment, the notch of the clearance slot 281 faces the socket 211. Such arrangement allows the push portion 221 of the pusher 220 to be provided between the notch of the clearance slot 281 and the socket 211, thereby enabling a compact arrangement of the pusher 220, the toggle member 280, and the door latch 100 inserted into the socket 211 in the accommodation cavity. As a result, the utilization rate of the internal space of the door lock device 10 is improved, and the volume of the door lock device 10 is reduced.

[0065] In an embodiment, the wall surface of the clearance slot 281 is arranged in a concave arc shape. This arrangement not only makes the clearance slot 281 easy to process, but also allows the clearance slot 281 to have enough space for the push portion 221 to be accommodated. That is, the clearance slot 281 with a concave arc-shape wall has a larger space to avoid the push portion 221, preventing the push portion 221 from exerting force on the wall of the clearance slot 281. This ensures that when the door 11 is opened, the toggle member 280 can quickly rotate to the engaged position, and the power supply of the motor can be quickly cut off, improving the response speed of the door lock device 10.

[0066] As shown in FIG. 2 to FIG. 4, in an embodiment, the pusher 220 includes a push support 222 rotatably installed in the accommodation cavity, and a connection rod 223, a limit rod 224 and a push rod 225 provided at the push support 222. The connection rod 223 has one end connected to the transmission assembly 240. The limit rod 224 and the push rod 225 are enclosed to form a slot 226 for receiving the door latch 100. The push rod 225 is configured to push the door latch 100 to retract from the accommodation cavity along the socket 211.

[0067] It can be understood that the connection rod 223, the limit rod 224 and the push rod 225 are in a strip shape. One end of the limit rod 224 is connected to the push support 222, and the other end of the limit rod 224 is configured to limit the door latch 100. One end of connection rod 223 is connected to the push support 222, and the other end of the connection rod 223 is connected to the transmission assembly 240, allowing the transmission assembly 240 to drive the connection rod 223 to rotate. One end of the push rod 225 is connected to the push support 222, and the other end of the push rod 225 is abutted against the toggle member 280.

[0068] Further, the limit rod 224 and the push rod 225 are enclosed to form the slot 226, and the slot 226 is engaged with the door latch 100. The door latch 100 can be engaged in the slot 226 to be securely positioned within the slot 226 after being inserted into the socket 211 of the lock housing 210. The push rod 225 is configured to push the door latch 100 to retract from the accommodation cavity along the socket 211, so that the door latch 100 can quickly and smoothly withdraw from the socket 211, enabling rapid opening of the door 11.

[0069] The door lock device of the present application includes the door latch and the door lock assembly. The door latch is installed at the door. The door lock assembly includes the lock housing, the pusher and the drive assembly. The lock housing is installed at the tank. The lock housing has the accommodation cavity and the socket for the door latch to be inserted or retracted. The pusher is rotatably installed in the accommodation cavity. The door latch is detachably connected to the pusher along the socket. The drive assembly is configured to drive the pusher to rotate. When the pusher rotates, it can push the door latch to retract from the accommodation cavity along the socket, to open the door of the dishwasher. With Such an arrangement, the door lock device of the present application can automatically open the door of the dishwasher, allowing the dishwasher to discharge the hot and humid steam inside the tank during the drying stage. This is beneficial for the dishwasher to achieve a better drying effect at a lower washing temperature. The lower washing temperature makes the dishwasher consume less power, thus reducing the energy consumption of the dishwasher. It can be seen that the door lock device of the present application can improve the drying effect of the dishwasher and reduce the energy consumption of the dishwasher.
