DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-2 As shown, a door lock of an industrial washing and drying machine includes a lock tongue 9, a lock box 3 and a lock block 6. The lock tongue 9 is connected to a handle 1 through a rotating shaft 8. The handle 1 is rotatably matched with the sealed door 2 (the handle is fixed to the sealed door through a fixed seat, and the handle and the fixed seat are rotatably matched. The rotating shaft is located in the fixed seat, and the handle can drive the rotating shaft to rotate. This is a conventional technology and is not described in detail in the drawings). The handle 1 drives the lock tongue 9 to rotate through the rotating shaft 8. The lock box 3 is fixed to the chassis of the industrial washing and drying machine. The lock block 6 is arranged in the lock box 3. Figure 3-4 As shown, a lock hole 603 for inserting a lock tongue 9 is provided at one end of the lock block 6, a tensioning platform 604 is provided inside the lock block 6, a stopper 605 for blocking the lock tongue 9 is provided at one end of the tensioning platform 604, a curved surface 608 from low to high is provided at the upper end of the tensioning platform 604, a door lock electromagnet 4 is provided at one side of the lock block 6, and a first clearance hole 601 is provided on the side wall of the lock block 6, as shown in FIG. Figure 6 As shown, when the door lock is closed, the lock tongue 9 moves along the curved surface 608 to the top of the curved surface 608, the iron core 401 of the door lock electromagnet 4 is inserted into the first clearance hole 601 and blocks the lock tongue 9, and the two sides of the lock tongue 9 are fixed by the iron core 401 and the block 605.

[0025] The highest end of the curved surface 608 is provided with a positioning groove 607 that cooperates with the lock tongue 9, which can position the lock tongue 9. There is a sealing ring on the sealing door 2. After the sealing door 2 is closed, the sealing ring is squeezed. As the lock tongue 9 rotates along the curved surface 608, the sealing door 2 is gradually tightened and the sealing ring is squeezed. When the lock tongue 9 cooperates with the positioning groove 607, the sealing ring will be restored by slight deformation, and the sealing door 2 will be sealed under the action of the sealing ring.

[0026] like Figure 5 As shown, the locking tongue 9 passes through the end of the rotating shaft 8 and is vertically connected. In order to reduce friction, rolling bodies 901 that cooperate with the curved surface 608 are sleeved on both ends of the locking tongue 9. The rolling body 901 is a needle bearing, and a retaining ring 902 for fixing the needle bearing is provided on the locking tongue 9.

[0027] The stopper 605 and the lock block 6 are an integral structure. A fixing hole 606 is provided on the stopper 605, and the lock block 6 and the lock box 3 are fixed by bolts.

[0028] A second clearance hole 602 is provided on the side wall of the locking block 6, and two tensioning platforms 604 are provided in the locking block 6, one of which cooperates with the iron core 401, and the highest position of the other tensioning platform 604 corresponds to the second clearance hole 602. A second micro switch 7 is provided on one side of the locking block 6, and the second driving rod 701 of the second micro switch 7 extends into the locking block 6 from the second clearance hole 602. After the lock tongue 9 is closed, it cooperates with the second driving rod 701, which indicates that the lock tongue 9 is closed. After the second micro switch 7 is triggered, the controller of the washing and drying machine pneumatic door lock electromagnet 4 fixes the lock tongue 9.

[0029] In addition, a first micro switch 5 is provided on one side of the door lock electromagnet 4, and a paddle 402 cooperating with a first driving rod 501 of the first micro switch 5 is provided on the iron core 401. When the iron core 401 is extended, the paddle 402 triggers the first micro switch 5, indicating that the door is locked at this time.

[0030] like Figure 2 As shown, when unlocking, the iron core 401 is reset, the lock tongue 9 contacts the limit, and the rotating shaft 8 is rotated by the handle 1. The rotating shaft 8 drives the lock tongue 9 to rotate along the curved surface 608 to a position corresponding to the lock hole 603. At this time, the lock tongue 9 can be pulled out of the lock hole 603 and the sealed door 2 can be opened.

[0031] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
