[0024] The door lock device 30 includes three states as follows: a first state is an unlocking state, where as shown in FIG. 2, the iron core 41 abuts against the door lock sliding block 31 and is not inserted into the groove 33, the iron core spring 44 is in a shrinkage state, the PTC heater is not power-on, the double-metal reed 52 is not deformed, and the locking piece 53 is not inserted into the notch 34, so neither the first latching part 40 nor the second latching part 50 latches the door lock sliding block 31, and at this time the washing machine door 20 is opened.

[0025] A second state is a locking state, where as shown in FIG. 3, when the washing machine door 20 is closed, the hook 21 is inserted into the clipping hole 32 and interacts with the door lock sliding block 31, so the door lock sliding block 31 moves and compresses the resetting spring 35 to shrink the resetting spring 35; as the door lock sliding block 31 moves, the iron core 41 is slowly inserted into the groove 33, the iron core spring 44 is restored to the natural state, the iron core 41 is inserted into the groove 33, and at this time the first latching part 40 latches the door lock sliding block 31 while the second latching part 50 does not lock the door lock sliding block 31, the washing machine door 20 is closed but is not deadlock, and the user may still open the washing machine door 20; a longitudinal section of a contact end of the iron core 41 and the door lock sliding block 31 is approximately trapezoidal, and a longitudinal section of the groove 33 is also approximately trapezoidal; in such design, in the state, when the washing machine door is opened with an external force, the iron core 41 is very easily separated from the groove 33, so that the washing machine door may be opened.

[0026] A third state is a deadlock state, where as shown in FIG. 4, in a case of the second state, when the washing machine works and the washing machine main controller 13 controls the second latching part 50 to work, the PTC heater is heated so that the double-metal reed 52 is deformed, the locking piece 53 disposed on the double-metal reed 52 is inserted into the notch 34 accordingly, and at this time, both the first latching part 40 and the second latching part 50 latch the door lock sliding block 31, the washing machine works and the washing machine door is deadlock. When all the washing programs of the washing machine end, the washing machine main controller 13 controls the first latching part 40 and the second latching part 50 to unlock the door lock sliding block 31, the iron core 41 is separated from the groove 33 by the action of an electromagnetic force, the locking piece 53 slowly quits the notch 34 as the double-metal reed 52 is restored to the original state, the door lock sliding block 31 returns to the initial state by the action of the resetting spring 35, and the washing machine door 20 automatically pops open. A contact end face of the hook 21 and the door lock sliding block 31 is a smooth curve, and in the procedure that the washing machine door 20 automatically pops open, the hook 21 is smoothly separated from the clipping hole 32 under the pushing of the door lock sliding block 31, so that the washing machine door smoothly pops open. In order that the washing machine door 20 automatically pops open with a good effect, in another implementation manner, a torsional spring device is disposed on the rotating shaft 22 of the washing machine door, and is used for applying a force popping open outward to the washing machine door 20 after the washing machine door 20 is unlocked.

[0027] In a novel control method of the washing machine, after washing programs are input and the washing machine is started, the washing machine main controller 13 controls the first latching part 40 and the second latching part 50 to lock the door lock sliding block 31; after all of the washing programs end, the washing machine main controller 13 controls the first latching part 40 and the second latching part 50 to unlock the door lock sliding block 31, the door lock sliding block 31 returns to the initial state by the action of the resetting spring 35, and the washing machine door 20 automatically pops open. However, in order that the washing machine door is opened after the temperature in the washing machine rotatable drum 60 is reduced, the washing machine main controller 13 may control the first latching part 40 and the second latching part 50 to unlock the door lock sliding block 31 in a predetermined time, generally one minute, and at this time the washing machine door 20 automatically pops open.

[0028] Various specific embodiments described in the foregoing and shown in accompanying drawings are only used for illustrating the present invention, and are not entirety of the present invention. Within the scope of the basic technical thought of the present invention, any types of modifications for the present invention made by persons ordinarily skilled in the art fall within the scope of the present invention.
