[0049] The other parts not described are the same as those in the first embodiment and will not be discussed again.

[0050] The third embodiment, as Figure 9-12 As shown, the bowl basket guide rail of the present dishwasher is different from that of the first embodiment in that the locking element 7 includes a locking rod 76 and a locking groove 77 arranged on the blocking member 4. The first end of the locking rod 76 is rotatably arranged on the mounting seat 5, and the second end of the locking rod 76 is provided with a movable block 78 that can be movably arranged in the locking groove 77 along the track of the locking groove 77. In this embodiment, except that the blocking end of the blocking member 4 protrudes outward from the mounting seat 5, there is no other component such as the elastic buckle 72 in the first embodiment and the elastic operating member in the second embodiment exposed on the mounting seat 5. The operator only needs to press the blocking member 4 The blocking member 4 can be switched between the two states by pressing, without the need to press the blocking member 4 and release the elastic buckle 72 as in the first embodiment to switch the blocking member 4 between the two states, and without the need to press the blocking member 4 and press the elastic operating member as in the second embodiment to switch the blocking member 4 between the two states. The solution of this embodiment has the advantages of low learning difficulty and simpler operation. The lock groove 77 includes at least a locking position 771 and a releasing position 772. The movable block 78 moves along the trajectory of the lock groove 77 in the lock groove 77 by the up and down movement of the blocking member 4. Fig.11As shown, when the movable block 78 is limited to the locking position 771, specifically, the movable block 78 moves to the locking position 771, and the blocking member 4 keeps the movable block 78 in the locking position 771 under the action of the elastic driving element 6, and the blocking member 4 is in an avoidance state. When the movable block 78 moves to the release position 772, the movable block 78 is no longer restricted, and the movable block 78 can move along the track of the locking groove 77, as shown in FIG. Fig.12 As shown, the blocking member 4 moves and switches to a blocking state under the action of the elastic driving element 6;

[0051] like Fig.10 As shown, the lock slot 77 includes an initial section 791, a lock section 792, a release section 793 and an end section 794. The initial section 791, the lock section 792, the release section 793 and the end section 794 are connected end to end in sequence to form a circulating track, so that the movable block 78 can circulate in the lock slot 77. The lock position 771 is located at the end of the lock section 792, and the release position 772 is located at the end of the release section 793 to prevent the movable block 78 from retreating from the release position 772 to the lock position 771. Along the path of the lock slot 77, the movable block 78 first reaches the lock position 771 and then reaches the release position 772.

[0052] The projections of the locking section 792 and the release section 793 on the horizontal plane overlap, and the movable block 78 can be switched between the locking section 792 and the release section 793 by moving the blocking member 4 up and down. Specifically, when the movable block 78 is located at the locking position 771 of the locking section 792, the blocking member 4 is pressed down, and the movable block 78 moves upward relative to the blocking member 4, and the movable block 78 moves to the release section 793 above the locking section 792 until it reaches the release position 772. A guide portion 795 for guiding the movable block 78 to enter is provided at the head end of the initial section 791. The setting of the guide portion 795 prevents the movable block 78 from entering the final section 794 first when it starts to run, and ensures that the movable block 78 runs along the trajectory of the predetermined initial section 791, the locking section 792, the release section 793 and the final section 794. The guide portion 795 is composed of an arc surface and / or an inclined surface.
