0 in the direction of arrow A in FIGS. 1A and 2 (direction of the dishwasher 1). At this time, since the pressing arm 8 also moves at the same time, the tip end 8a of the pressing arm 8 moves forward while pushing one side of the rack 5. Then, when the forward end detection limit switch 14 detects the dog 13 of the carrier 12, the drive of the motor 24 is temporarily stopped, and the rack 5 is thereby carried into the predetermined position of the dishwasher 1.

Subsequently, the motor 24 rotates in the opposite direction, and the carrier 12 moves in the direction of arrow B in FIG. 2 in the same manner as described above. Then, when the backward end detection limit switch 15 detects the dog 13 of the carrier 12, the driving of the motor 24 is stopped, the pressing arm 8 is returned to the initial position, and one cycle of rack loading is completed.

Next, the operation of the rack unloading mechanism 26 will be explained.

When the washing of the rack 1 in the dishwasher 1 is completed and the lid of the dishwasher 1 is opened as shown in FIG. 1b, a lid opening signal is sent and a control panel (not shown) is displayed. Then, in the same manner as described above, the motor 44 shown in FIG.

At this time, the carrier 32 is in the initial position near the limit switch 34 for detecting the backward end, and the carrier case 46 is moved toward the back of the clean table 3 (direction C) against the biasing force of the spring (tension) 49, as will be described later. The roller shaft 51 is in sliding contact with the inside of the frame 29.

In this state, the carrier 32 is connected to the guide bar 30,
30 in the direction of arrow B (direction of the dishwasher 1). In this case, the latching arm 28
However, as mentioned above, since the carrier case 46 is moving toward the back of the clean table 3 (direction C), the latch arm 28 also moves close to the front wall of the frame 29, and the rack 5 can move forward without touching.

In the carrier 32, a dog 33 provided on the carrier 32 is connected to a limit switch 35 for detecting the forward end.
It stops when it comes into contact with and the forward end position is detected.
At this stop position, as shown by the solid line in FIG.
3, and the carrier case 4
6, that is, the roller shaft 51 is a spring (tension) 4
The cleaning table 3 jumps over the notch 53 with the urging force of 6 and moves in the front direction (direction D) of the clean table 3. For this reason, the latch arm 28 has a latch portion 28a at its tip.
The rack 5 inside the dishwasher 1 can be hooked up with this button.

The operations described above, from the stop of the carrier 32 until the carrier case 46 moves and the hooking arm 28 hooks the rack 5, are performed within the timer time (motor stop time) preset by the control unit. When this time period has elapsed, the motor 44 rotates in the reverse direction, and the latch arm 28 begins to move toward the rearward end position of the carrier 32 while conveying the rack 5.

At this time, the roller shaft 51 moves backward while contacting the front wall of the frame 29, so the carrier case 46 and the latch arm 28 can move stably, and the latch part 28a is removed from the rack 5. It can be transported to a predetermined unloading position without difficulty.

When the rack 5 reaches the rack unloading position of the clean table 3, the roller shaft 51 moves the slider 55 by a slight amount against the biasing pressure of the spring (compression) 54, as shown by the broken line in FIG. Move backwards. At the same time, due to the cooperative action of the tapered end surface 55a of the slider 55 and the repulsive force of the spring (compression) 54, the roller shaft 51 jumps over the notch 52 of the frame 29 and is directed from the front wall of the frame 29 toward the inner wall. Pushed in.

In this way, the slider 55 closes the notch 52 again, and the locking portion 28a of the locking arm 28
is removed from the rack 5, the carrier 32 moves until the dog 33 comes into contact with the backward end detection limit switch 34, and then stops, completing one cycle of rack unloading.
