The lock tongue 210 can also be locked on the lock 300 to enable the door body 200 to be locked on the laundry throwing opening. At this time, the lock tongue 210 and the lock 300 are in the locking state. The lock tongue 210 can be in contact with the lock 300 but in no connection state, which is the unlocking state. During the process of opening the door body 200, the lock tongue 210 can also be completely disengaged from the lock 300, and the lock tongue 210 and the lock 300 are in the disengaging state.

[0070] Specifically, Figure 8 A structure diagram of the opening and closing door device is shown Figure 9 A sectional view of the opening and closing door device is shown, refer to Figure 3 、 Figure 4 、 Figure 8 and Figure 9The opening and closing door device 400 is arranged at the rotating connection between the door body 200 and the cabinet 100, and can drive the door body 200 to rotate from the first preset angle to the third preset angle or from the third preset angle to the second preset angle. When the door body 200 rotates from the first preset angle to the third preset angle, the lock 300 can connect the lock bolt 210 and drive the door body 200 to rotate to close the clothes feeding opening. When the lock bolt 210 and the lock 300 are switched from the separable positioning state to the unlocking state, the opening and closing door device 400 can drive the door body 200 to rotate to the second preset angle, which is greater than the third preset angle. The first preset angle, the second preset angle and the third preset angle are all the included angle between the door body 200 and the clothes feeding opening.

[0071] More specifically, the opening and closing door device 400 includes a cam 410 and an energy storage assembly 420. The cam 410 and the energy storage assembly 420 are connected between the door body 200 and the cabinet 100. During the opening of the door body 200, after the lock bolt 210 and the lock 300 are switched from the locking state to the separable positioning state, the energy storage assembly 420 and the cam 410 rotate relative to each other to make the door body 200 open to the second preset angle. During the closing of the door body 200, after the door body 200 closes to the first preset angle, the energy storage assembly 420 and the cam 410 rotate relative to each other to make the door body 200 continue to close to the third preset angle.

[0072] Optionally, in the embodiment, the energy storage assembly 420 is movably arranged on the door body 200, and the cam 410 is coaxially fixedly connected to the hinge shaft 220 of the door body 200.

[0073] In another embodiment, the cam 410 can rotate with the door body 200, and the energy storage assembly 420 is arranged on the cabinet 100. The energy storage assembly 420 and the cam 410 can rotate relative to each other, as shown in Figure 11

[0074] During the closing of the door body 200, when the door body 200 closes to the first preset angle, the lock bolt 210 and the lock 300 are still in the disengaged state. After the door body 200 closes to the first preset angle, the energy storage assembly 420 can automatically act, and the energy storage assembly 420 and the cam 410 rotate relative to each other to make the door body 200 continue to close to the third preset angle to close the clothes feeding opening. When the door body 200 is at the third preset angle, the lock bolt 210 contacts but is not connected to the lock 300, and the two are in the separable positioning state. When the lock bolt 210 and the lock 300 are in the separable positioning state, if the clothes treatment equipment sends a locking start signal, the lock 300 can act to lock the lock bolt 210, so that the two are switched to the locking state.​

[0075] In the embodiment, the first preset angle can be specifically 30°-50°, and the third preset angle can be specifically 2°-5°. The first preset angle is specifically preferably 45°, and the third preset angle is specifically preferably 3°. Through the above setting, the degree of automation of the door closing process of the clothes treatment equipment can be improved, so as to improve the user experience.

[0076] In the opening process of the door body 200, after the lock tongue 210 and the lock 300 are switched from the locked state to the unlocked state, the energy storage assembly 420 can automatically act, and the energy storage assembly 420 and the cam 410 are relatively rotated to open the door body 200 to the second preset angle. At this time, the water vapor in the cabinet 100 can be released to avoid the breeding of bacteria and peculiar smell. In the embodiment, the second preset angle can be specifically 30°-50°, and the second preset angle and the first preset angle can be equal or not equal. The second preset angle is specifically preferably 45°.

[0077] Continuing to refer to Figures 5-7 The lock 300 includes a fixed shell 310, a pre-tightening piece 320, and a pre-tightening elastic element 330. The fixed shell 310 is installed on the cabinet 100, the pre-tightening piece 320 is swingably arranged in the fixed shell 310, the pre-tightening elastic element 330 is connected between the pre-tightening piece 320 and the fixed shell 310, and the pre-tightening piece 320 can be in a pre-tightening position. The lock tongue 210 is provided with a clamping groove 211, and the lock tongue 210 can extend into the fixed shell 310. When the lock tongue 210 and the lock 300 are in a separable positioning state, the pre-tightening piece 320 swings to the pre-tightening position and is clamped in the clamping groove 211. At this time, the lock tongue 210 is connected with the lock 300, but is not locked. Before the washing process of the clothes treatment equipment starts, the user can pull the door body 200 to separate the lock tongue 210 from the pre-tightening piece 320 and pull the lock tongue 210 out of the fixed shell 310 to open the door body 200.

[0078] Specifically, referring to Figure 6 The pre-tightening piece 320 is provided with a pre-tightening protrusion 321 which can be clamped in the clamping groove 211. The groove wall of the clamping groove 211 is ramp-shaped, and the pre-tightening protrusion 321 is provided with a ramp-shaped guide surface. In the process of switching the lock tongue 210 and the lock 300 from the unlocked state to the separable positioning state, the ramp-shaped guide surface can slide relative to the groove wall of the clamping groove 211 to make the pre-tightening protrusion 321 enter the clamping groove 211. In the process of switching the lock tongue 210 and the lock 300 from the separable positioning state to the separated state, the ramp-shaped guide surface can slide relative to the groove wall of the clamping groove 211 to make the pre-tightening protrusion 321 move out of the clamping groove 211.

[0079] More specifically, the ramp-shaped guide surface is divided into an entry ramp and an exit ramp, the entry ramp has a smaller slope angle, which is beneficial to reduce the resistance when the pre-tightening protrusion 321 enters the clamping groove 211; the exit ramp has a larger slope angle, which is beneficial to achieve the positioning force value of the set separable positioning state.

[0080] More specifically, the lock 300 further comprises a swing housing 340 and a locking member. The swing housing 340 is swingably arranged in the fixed housing 310, and the swing housing 340 can swing to switch between a locking position and an unlocking position, and the swing axis 341 of the swing housing 340 is located at one of the top corners of the swing housing 340. The locking member is arranged in the swing housing 340 and is spaced apart from the pre-tightening member 320, and the lock tongue 210 can extend into the space between the pre-tightening member 320 and the locking member. When the swing housing 340 swings to the locking position, the locking member can be connected to the lock tongue 210, and the locking member can further lock with the lock tongue 210 under its own action. When the swing housing 340 swings to the unlocking position, the locking member can be separated from the lock tongue 210, and at this time the lock tongue 210 and the lock 300 are in a separable positioning state.

[0081] More specifically, in the present embodiment, the locking member is a locking screw 350, the locking screw 350 is provided with an involute screw structure on the side surface, and the locking screw 350 is rotatably arranged in the swing housing 340 about its own axis. The side of the lock tongue 210 away from the clamping groove 211 is provided with a tooth-shaped locking portion 212, the locking screw 350 can be rotated to make the tooth-shaped locking portion 212 mesh with the locking screw 350, and the locking screw 350 can also be reversely rotated to drive the lock tongue 210 to exit between the pre-tightening member 320 and the locking screw 350.

[0082] More specifically, the lock 300 further comprises a first driving device 360 and a second driving device 370. The first driving device 360 is arranged in the swing housing 340 and is drivingly connected to the fixed housing 310, and can drive the swing housing 340 to swing relative to the fixed housing 310 to switch between the locking position and the unlocking position. The second driving device 370 is arranged on the swing housing 340 and is drivingly connected to the locking screw 350, and can drive the locking screw 350 to act to lock with the lock tongue 210 or drive the lock tongue 210 to exit between the pre-tightening member 320 and the locking screw 350 to form an unlocking state, and can also drive the lock tongue 210 to extend into the space between the pre-tightening member 320 and the locking screw 350. In the present embodiment, the first driving device 360 and the second driving device 370 can both be driving motors in the prior art.

[0083] More specifically, the lock 300 further comprises a lock bolt approaching sensor, a lock bolt in place sensor and a swing position sensor. The lock bolt approaching sensor is capable of sending a lock bolt approaching signal when the lock bolt 210 approaches the lock 300, at which time the first driving device 360 starts to drive the swing housing 340 to swing from the unlocking position to the locking position. It should be noted that when the user is in a hurry, the door body 200 can be directly closed to the clothes feeding opening by pushing the door body 200, i.e. the lock bolt 210 is quickly inserted into the space between the pre-tightening member 320 and the locking screw 350, at which time no collision or other problems will occur because the swing housing 340 is still in the unlocking position.

[0084] When the lock bolt 210 moves to the position connected to the pre-tightening member 320, the lock bolt in place sensor sends a lock bolt in place signal, at which time the first driving device 360 drives the swing housing 340 to swing from the locking position to the unlocking position, so that the lock bolt 210 is only positioned by the pre-tightening member 320, at which time the lock bolt 210 and the lock 300 are in a separable positioning state, at which time the user can pull the door body 200 to open the clothes feeding opening and perform other operations such as adding clothes.

[0085] The swing position sensor is capable of detecting the swing position of the swing housing 340 to determine whether the swing housing 340 is in the unlocking position or the locking position. When the swing housing 340 detects that the swing housing 340 is in the unlocking position and the clothes treatment apparatus sends a locking start signal, the first driving device 360 is capable of driving the swing housing 340 to swing from the unlocking position to the locking position, and the second driving device 370 is capable of driving the locking screw 350 to lock with the lock bolt 210. After the above process is completed, the door body 200 is locked at the clothes feeding opening, thereby ensuring the safe performance of the subsequent washing process.

[0086] More specifically, continuing to refer to Figure 5 and Figure 7 , the lock 300 further comprises a transmission rack 381 and a transmission gear set 390, the first driving device 360 and the transmission gear set 390 are in transmission connection and are both connected to the swing housing 340. The fixed housing 310 is provided with a sliding groove 311, the transmission rack 381 is arranged in the sliding groove 311 and is engaged with the transmission gear set 390, the first driving device 360 is capable of driving the transmission gear set 390 to rotate to drive the swing housing 340 to swing relative to the fixed housing 310 along the extension direction of the sliding groove 311 to switch between the unlocking position and the locking position.

[0087] As preferred, the lock 300 further comprises a swing elastic element 382. The transmission rack 381 is movably arranged in the sliding groove 311, and the swing elastic element 382 is connected between one end of the transmission rack 381 and the abutting boss 313 in the fixed shell 310. In the process of swinging the swing shell 340 from the unlocking position to the locking position, the transmission rack 381 can move in the sliding groove 311, and the swing elastic element 382 can be compressed to store energy. When the tooth-shaped locking portion 212 cannot be engaged with the helical teeth of the locking screw 350, the swing shell 340 cannot be temporarily swung to the locking position. At this time, the first driving device 360 drives the transmission gear set 390 to rotate, thereby driving the transmission rack 381 to move in the direction of the swing elastic element 382, and the swing elastic element 382 is compressed to store energy. At the same time, the second driving device 370 drives the locking screw 350 to rotate, and the helical teeth of the rotating locking screw 350 move relative to the teeth of the tooth-shaped locking portion 212. When the teeth of the two are moved to be offset from each other and the tooth top is opposite to the tooth groove, the two can be quickly engaged under the elastic action of the swing elastic element 382, so that the swing shell 340 is swung to the locking position.

[0088] As preferred, the fixed shell 310 is provided with an opening 312 on the side, and a pull rope (not shown) is connected to the swing shell 340, and the pull rope can extend out of the opening 312. The pull rope can drive the swing shell 340 to swing relative to the fixed shell 310, so that the swing shell 340 swings from the locking position to the unlocking position. That is, in an emergency, the user can pull the swing shell 340 to swing through the pull rope, and the transmission rack 381 and the transmission gear set 390 swing together with the swing shell 340 in the direction of being pulled, and in this process, the swing elastic element 382 is compressed, so that the bolt 210 is separated from the locking screw 350 to be unlocked, the manual door opening is realized, the damage to the entire clothes treatment equipment and the opening and closing door device 400 is avoided, and the safety and reliability of the product are ensured. It should be noted that the pull rope can be a soft plastic rope or a flexible strip of other materials.

[0089] Figure 10 A structure schematic diagram of a cam is shown. Referring to Figures 8-10 The cam 410 is provided with an automatic door opening track 411, a manual door opening energy storage track 412, a manual door opening and closing track 413, and an automatic door closing track 414, and the energy storage assembly 420 can move relative to the automatic door opening track 411, the manual door opening energy storage track 412, the manual door opening and closing track 413, or the automatic door closing track 414.

[0090] Specifically, during the opening process of the door body 200, the energy storage assembly 420 moves relatively along the automatic door opening track 411 and the manual door opening energy storage track 412 in sequence. During the closing process of the door body 200, the energy storage assembly 420 moves relatively along the manual door closing track 413 and the automatic door closing track 414 in sequence.

[0091] Specifically, the opening and closing door device 400 further comprises a bracket 430, and the energy storage assembly 420 comprises a first sleeve 421, a second sleeve 422, a ball 423, an opening and closing door elastic element 424 and a rotating shaft 425. The ball 423, the second sleeve 422 and the opening and closing door elastic element 424 are coaxially arranged and are all arranged in the first sleeve 421. The ball 423 is movably arranged at the front end of the second sleeve 422, and the opening and closing door elastic element 424 is clamped between the inside of the tail end of the second sleeve 422 and the tail end of the first sleeve 421. The rotating shaft 425 is arranged in the hole at the tail end of the first sleeve 421 and the hole at the tail end of the bracket 430. The first sleeve 421 can swing relative to the bracket 430 around the rotating shaft 425. The bracket 430 is arranged on the door body 200, and the front end of the bracket 430 is rotatably sleeved on the hinge shaft 220.

[0092] With reference to Figure 11 In another embodiment, the bracket 430 is fixedly arranged on the inner wall of the cabinet 100, the energy storage assembly 420 is arranged in the bracket 430, and the cam 410 is fixedly arranged on the door body 200 and can rotate together with the door body 200, so as to realize the relative movement of the energy storage assembly 420 and the cam 410.

[0093] When the laundry treating apparatus needs to be opened, the second driving device 370 drives the locking screw 350 to rotate, so that the locking screw 350 and the tooth-shaped locking portion 212 are disengaged and unlocked. The elastic force of the opening and closing door elastic element 424 causes the ball 423 to roll and move on the automatic door opening track 411 of the cam 410, and an outward opening force is generated, so that the door is opened to a second preset angle, and the automatic opening action of the laundry treating apparatus is completed. When the door is subsequently manually opened to a larger opening angle, the ball 423 rolls and moves on the manual door opening energy storage track 412 of the cam 410, so that the opening and closing door elastic element 424 is compressed to store energy.

[0094] When the door of the washing machine is closed, the door body 200 rotates to drive the hinge shaft 220 to rotate, so that the ball 423 rolls along the manual door opening track 413 on the cam 410 and moves to the automatic door closing track 414, at this time the door body 200 is closed to the first preset angle, the opening and closing door device 400 generates a force to close the door inward, and the door body 200 continues to automatically rotate a certain stroke to the third preset angle, the locking tongue 210 contacts the locking screw 350, and then is clamped with the pre-tightening member 320 under the action of the locking screw 350 to form pre-tightening, so that the door body 200 is closed to the clothes throwing opening.

[0095] By setting the automatic door opening track 411 and the automatic door closing track 414 on the cam 410, cooperating with the elastic force of the opening and closing door elastic element 424 and the rolling of the ball 423, only the door needs to be manually closed to the first preset angle during washing, and then automatic door closing can be realized, the degree of automation of the door closing process is improved, and the use experience of the user is improved. When the clothes are washed, the lock 300 is automatically unlocked to unlock the locking screw 350 and the locking tongue 210, and the opening and closing door device 400 can generate a force to open the door outward, so that the door body 200 is automatically opened to the second preset angle, the water vapor in the box body 100 is released, bacteria and peculiar smell are prevented from breeding, and the use experience is improved.
