When tableware needs to be placed in the pull-out basket, the drawer is opened firstly, the pull-out basket is exposed, and then the tableware which is just cleaned is placed in the pull-out basket. The dishes are usually placed vertically in the baskets so that the water on the surface of the dishes drips under the action of gravity and dries the surface of the dishes. Because the surface of the tableware which is just cleaned is provided with water, when the tableware is just placed on the pull basket and the drawer is not closed, the water can drip on the ground through the hollow parts on the pull basket to wet the ground, so that the ground is wet and slippery, and potential safety hazards are brought; meanwhile, the moisture can adsorb dust, which is not sanitary.

The working principle of the embodiment is as follows:

(1) in the initial state, as shown in fig. 2 and 6, no external force acts on the pull rod 221 for the upper and lower drawers 2, and the sliding rod 222 is located in the middle of the limiting hole 211 under the action of the first elastic member 51 and the second elastic member 52; meanwhile, since the user does not touch the sensor 2211, the output shaft 411 retracts, and the orthographic projections of the second magnetic block 42 and the first magnetic block 31 on the vertical plane perpendicular to the front-rear direction are away from each other;

(2) when a user opens the drawer 2 located above, in the process of pulling the pull rod 221 to move forward, the slide rod 222 is driven to move forward and compress the second elastic piece 52 until the slide rod moves to the front of the limiting hole 211, meanwhile, the sensor 2211 acquires a touch signal, and after the electric push rod 41 receives the signal, the output shaft 411 of the electric push rod extends outwards to drive the second magnetic block 42 to move downward and be attached to and adsorbed by the first magnetic block 31, so that when the pull rod 221 is pulled forward continuously as shown in fig. 3, the slide rod 222 moving forward can drive the drawer 2 located above to move forward, and the second magnetic block 42 moving forward can drive the first magnetic block 31 to move forward, thereby realizing synchronous forward movement of the water pan 3 and the drawer 2; meanwhile, the drawer 2 positioned below has no external force, and the orthographic projections of the corresponding second magnetic blocks 42 and the corresponding first magnetic blocks 31 on the vertical plane vertical to the front-back direction are far away from each other, so that the first magnetic blocks 31 moving back and forth do not interfere with the second magnetic blocks 42;

similarly, when the user opens the drawer 2 located below, as shown in fig. 7, the sliding rod 222 moving forward can drive the drawer 2 located above to move forward, and the second magnetic block 42 moving forward can drive the first magnetic block 31 to move forward, so as to achieve synchronous forward movement of the water pan 3 and the drawer 2; meanwhile, the drawer 2 positioned above has no external force, and the orthographic projections of the corresponding second magnetic blocks 42 and the corresponding first magnetic blocks 31 on the vertical surface vertical to the front-back direction are far away from each other, so that the first magnetic blocks 31 moving back and forth do not interfere with the second magnetic blocks 42;

(3) when a user closes the drawer 2 located below, in the process of pulling the pull rod 221 to move backwards, the slide rod 222 is driven to move backwards and compress the first elastic piece 51 until the slide rod moves to the rear part of the limiting hole 211, meanwhile, the sensor 2211 acquires a touch signal, and after the electric push rod 41 obtains the signal, the output shaft 411 of the electric push rod extends outwards to drive the second magnetic block 42 to move downwards and be attached to and adsorbed by the first magnetic block 31, so that when the pull rod 221 continues to be pushed backwards, the slide rod 222 moving backwards can drive the drawer 2 located above to move backwards, and the second magnetic block 42 moving backwards can drive the first magnetic block 31 to move backwards, so that the water receiving tray 3 and the drawer 2 can move backwards synchronously; meanwhile, the drawer 2 positioned above has no external force, and the orthographic projections of the corresponding second magnetic blocks 42 and the corresponding first magnetic blocks 31 on the vertical surface vertical to the front-back direction are far away from each other, so that the first magnetic blocks 31 moving back and forth do not interfere with the second magnetic blocks 42;

similarly, when the user closes the drawer 2 located below, as shown in fig. 8, the sliding rod 222 moving backwards can drive the drawer 2 located below to move backwards, and the second magnetic block 42 moving backwards can drive the first magnetic block 31 to move backwards, so that the water pan 3 and the drawer 2 move backwards synchronously; meanwhile, the drawer 2 positioned above has no external force, and the orthographic projections of the corresponding second magnetic blocks 42 and the corresponding first magnetic blocks 31 on the vertical surface vertical to the front-back direction are far away from each other, so that the first magnetic blocks 31 moving back and forth do not interfere with the second magnetic blocks 42;

in the scheme, when the user drives the pull rod 221 to stay at any position, the drawer 2 and the water pan 3 can be positioned at the position, so that stepless positioning is realized, the water pan 3 can effectively receive water dropping from the drawer 2, and the operation is convenient and reliable; and once the user releases the pull rod 221, the orthographic projections of the corresponding second magnetic blocks 42 and the first magnetic blocks 31 on the vertical plane perpendicular to the front-back direction are far away from each other, therefore, the first magnetic block 31 moving forward and backward does not interfere with the second magnetic block 42, does not affect the driving of the other second magnetic blocks 42 to the corresponding first magnetic blocks 31, and the drawers 2 do not interfere with each other, for example, during the opening process of one drawer 2, after a user pulls the pull rod 221 on the drawer 2 to drive the drawer 2 and the water pan 3 to move to the middle position and release the pull rod 221, a user can pull the pull rod 221 on the other drawer 2 to drive the other drawer 2 to move forward until the corresponding second magnetic block 42 is attached to and adsorbed by the first magnetic block 31, and at the moment, the pull rod 221 is continuously pulled to drive the other drawer 2 and the water pan 3 to move forward synchronously without interference;

in addition, the pull rod 221 can be movably installed on the drawer 2 back and forth through the sliding rod 222, so that the pull rod 221 has a section of moving stroke, the moving stroke endows the transmission assembly 4 with a certain reaction time, the second magnetic block 42 can be adsorbed to the first magnetic block 31 before the pull rod 221 drives the drawer 2 to move, and the situation that the second magnetic block 42 moves downwards after the drawer 2 moves for a certain distance and is mistakenly matched with the first magnetic block 31 is avoided; in particular, in the above solution, the sliding rod 222 is located in the middle of the limiting hole 211 under the action of the first elastic member 51 and the second elastic member 52, so that whether the pull rod 221 is pulled forward or pushed backward, the pull rod 221 always has a forward or backward moving stroke at one end, and it is ensured that the electric push rod 41 has enough reaction time to drive the second magnetic block 42 to move downward.
