Background

The existing disinfection cabinet generally comprises a cabinet body with a disinfection cavity and a drawer capable of entering and exiting the disinfection cavity, wherein the drawer generally comprises a hollow pull basket, and tableware is placed in the pull basket combined by a plurality of metal strips. 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 also adsorb dust and is not sanitary.

Therefore, people design the disinfection cabinet with the drawer type water receiving tray, when the bowl tray is placed, water dropping on the bowl tray can be received by the drawer type water receiving tray, and therefore the ground can be prevented from being wetted and polluted. However, for the existing water pan, the user needs to manually drive the water pan according to needs when the water pan is opened or closed, which is inconvenient, the drawer and the water pan cannot move synchronously, and the water pan cannot be automatically opened or closed according to the opening or closing state of the drawer.

Specifically, the support stand 61 is supported below the drip tray 3; the driving piece 62 is a push rod motor, is mounted on the bottom wall inside the cabinet body 1, and has a power output end connected to the bottom of the supporting platform 61, and is used for driving the supporting platform 61 to move along the vertical direction and the left-right direction; the controller is integrated on the driving part 62 and is electrically connected with the first sensor and the driving part 62, so that the controller can receive the signals collected by the first sensor and control the driving part 62 to drive the supporting platform 61 and the water pan 3 to synchronously move;

the pull rod 221 can drive the sliding rod 222 to move synchronously under the action of an external force, so that the sliding rod 222 has at least three states:

in the first state, as shown in fig. 2, 3, 4 and 8, no external force acts on the pull rod 221, and the slide 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, because the user does not touch the first sensor, the second rack 44 of each transmission assembly 4 is separated from the second gear 43, so that each drawer 2 and the water pan 3 have no linkage relation, and the water pan 3 can move freely;

in the second state, as shown in fig. 5, 6, 9 and 10, an external force acts on the pull rod 221 and moves forward, and the slide rod 222 moves to the front of the limiting hole 211 against the elastic force of the second elastic member 52, so that the slide rod 222 moving forward can drive the drawer 2 to move forward; meanwhile, the first sensor collects a touch signal, and after the driving part 62 obtains the signal, the water pan 3 is moved through the supporting platform 61 until the second rack 44 in the transmission assembly 4 corresponding to the drawer 2 is meshed with the second gear 43, so that the drawer 2 which moves forwards can drive the water pan 3 to move forwards synchronously; meanwhile, the second racks 44 in the transmission assemblies 4 corresponding to other drawers 2 are separated from the second gear 43, so that other drawers 2 and the water pan 3 have no linkage relationship and cannot generate an interference phenomenon;

in a third state, as shown in fig. 7 and 11, an external force acts on the pull rod 221 and moves backward, and the sliding rod 222 moves to the rear of the limiting hole 211 against the elastic force of the first elastic member 51, so that the backward moving sliding rod 222 can drive the drawer 2 to move backward; meanwhile, the first sensor collects a touch signal, and the driving part 62 moves the water pan 3 through the supporting platform 61 after obtaining the signal until the second rack 44 in the transmission assembly 4 corresponding to the drawer 2 is meshed with the second gear 43, so that the backward-moving drawer 2 can drive the water pan 3 to synchronously move backwards; meanwhile, the second rack 44 in the transmission assembly 4 corresponding to the other drawer 2 is separated from the second gear 43, so that no linkage relation exists between the other drawer 2 and the water pan 3, and no interference phenomenon occurs.

The working principle of the embodiment is as follows:

(1) in the initial state, as shown in fig. 2, 3, 4 and 8, for the upper and lower drawers 2, no external force acts on the pull rod 221, and the slide bar 222 is located in the middle of the limit hole 211 under the action of the first elastic member 51 and the second elastic member 52; meanwhile, because the user does not touch the first sensor, the second rack 44 in each transmission assembly 4 is separated from the second gear 43, so that there is no linkage relationship between each drawer 2 and the water pan 3, and the water pan 3 can move freely, for example, accumulated water is poured out, and the interference phenomenon with the drawer 2 does not occur;

(2) when a user opens the drawer 2 located above and touches the sensing area 221A, during the process of pulling the pull rod 221 to move forward, the sliding rod 222 is driven to move forward and compress the second elastic member 52 until the sliding rod moves to the front of the limiting hole 211, and at the same time, the first sensor acquires a touch signal, the driving member 62 receives the signal, and then the water tray 3 is moved through the support platform 61 until the second rack 44 in the transmission assembly 4 corresponding to the drawer 2 is engaged with the second gear 43, so that, as shown in fig. 5 and 6, when the pull rod 221 continues to be pulled forward, the sliding rod 222 moving forward can drive the drawer 2 located above to move forward, the first rack 41 moving forward can drive the first gear 42 to rotate, the driving wheel 45 rotates synchronously, the driven wheel 46 rotates synchronously under the action of the transmission belt 47 and drives the second gear 43 to rotate, and finally the water tray 3 is driven by the second rack 44 to move forward, thereby realizing the synchronous forward movement of the water pan 3 and the drawer 2; meanwhile, the drawer 2 positioned below has no external force, the drawer 2 and the water pan 3 have no linkage relation, and the two drawers 2 do not have interference phenomenon;

similarly, when the user opens the drawer 2 located below and touches the sensing area 221A, as shown in fig. 9 and 10, the sliding rod 222 moving forward can drive the drawer 2 located below to move forward, and the first rack 41 moving forward can finally drive the second rack 44 to move forward, so that the water receiving tray 3 and the drawer 2 move forward synchronously; meanwhile, the drawer 2 positioned above has no external force, the drawer 2 and the water pan 3 have no linkage relation, and the two drawers 2 do not have interference phenomenon;

(3) when a user closes the drawer 2 located below and touches the sensing area 221A, in the process of pulling the pull rod 221 to move backwards, the slide bar 222 is driven to move backwards and compress the first elastic member 51 until the slide bar moves to the rear part of the limiting hole 211, meanwhile, the first sensor acquires a touch signal, the electric push rod 41 obtains the signal, and then the water receiving tray 3 is moved through the support table 61 until the second rack 44 in the transmission assembly 4 corresponding to the drawer 2 is meshed with the second gear 43, so that, as shown in fig. 7, when the pull rod 221 is pushed backwards continuously, the slide bar 222 moving backwards can drive the drawer 2 located above to move backwards, the first rack 41 moving backwards drives the first gear 42 to rotate, the driving wheel 45 rotates synchronously, the driven wheel 46 rotates synchronously under the action of the transmission belt 47 and drives the second gear 43 to rotate, and finally the water receiving tray 3 is driven to move backwards through the second rack 44, thereby realizing the synchronous backward movement of the water pan 3 and the drawer 2; meanwhile, the drawer 2 positioned below has no external force, the drawer 2 and the water pan 3 have no linkage relation, and the two drawers 2 do not have interference phenomenon;

similarly, when the user closes the drawer 2 located below and touches the sensing area 221A, as shown in fig. 11, the sliding rod 222 moving backwards can drive the drawer 2 located below to move backwards, and the first rack 41 moving backwards can finally drive the second rack 44 to move backwards, so that the water receiving tray 3 and the drawer 2 move backwards synchronously; meanwhile, the drawer 2 positioned above has no external force, the drawer 2 and the water pan 3 have no linkage relation, and the interference phenomenon between the two drawers 2 can not occur;

(4) when a user opens or closes the drawer 2 and touches the non-sensing area 221B, the first sensor does not acquire a touch signal, and the drawer 2 and the water receiving tray 3 are not linked, so that when the dry tableware is taken and placed, the water receiving tray 3 can be prevented from entering and exiting along with the entering and exiting of the drawer 2, and the tableware drying device is more trouble-saving, energy-saving and more convenient;

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; once a user releases the pull rod 221, the water receiving tray 3 can reset, the second rack 44 in each transmission assembly 4 can be separated from the second gear 43, the driving of other drawers 2 to the water receiving tray 3 is not influenced, and the drawers 2 are not interfered with each other;

in addition, the pull rod 221 can be movably mounted on the drawer 2 back and forth through the sliding rod 222, so that the pull rod 221 has a moving stroke, the moving stroke endows the driving mechanism 6 with a certain reaction time, the corresponding second rack 44 can be meshed with the second gear 43 before the pull rod 221 drives the drawer 2 to move, and the condition that the two are meshed after the drawer 2 moves for a certain distance to cause inconsistent strokes 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 driving mechanism 6 has enough reaction time to drive the water pan 3 to move.

Example 2:

fig. 12 shows a preferred embodiment of the drawer cabinet of the present invention. The difference from example 1 is that:

in this embodiment, the sensed member 31 is mounted on the side of the water pan 3, the second sensor 232 corresponding to the sensed member 31 is mounted on the side of each drawer 2, and is used for detecting whether the drawer 2 is located right above the water pan 3, and the second sensor 232 is electrically connected to the controller. Specifically, in a state where the drawer 2 is positioned directly above the drip tray 3, the sensor 31 is positioned directly below the corresponding second sensor 232, so that the second sensor 232 senses a signal to transmit to the controller.

When a user touches the first sensor of one drawer 2 and the drawer 2 is positioned right above the water receiving tray 3, the second rack 44 in the transmission assembly 4 corresponding to the drawer 2 is meshed with the second gear 43, and the second racks 44 in the transmission assemblies 4 corresponding to the other drawers 2 are separated from the second gear 43.

According to the scheme, the phenomenon that the water pan 3 has asynchronous strokes when different drawers 2 move in a staggered mode can be avoided, for example, in the process of opening one drawer 2, when 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, the user can pull the pull rod 221 on the other drawer 2 to drive the drawer 2 to move forward for an idle stroke until the drawer 2 moves right above the water pan 3, at the moment, the pull rod 221 is continuously pulled to drive the drawer 2 and the water pan 3 to move forward synchronously, and the stroke synchronization is guaranteed.
