gear switching module

3, 3 actions are switched so that transmission module and bottom plate 21 are established and are connected in order to form automatic gear through control module control gear, or make transmission module and bottom plate 21 disconnection in order to form manual gear. The dishwasher is simple in structure, can realize stable switching between the automatic mode and the manual mode by controlling whether the transmission module is connected with the bottom plate 21 or not, and further improves the use experience of users.

Further, the gear shifting module 3 includes a motor assembly 31 and a gear lifting mechanism 32, wherein the motor assembly 31 drives the transmission module to lift through the gear lifting mechanism 32 so as to connect the transmission module with the bottom plate 21 or disconnect the transmission module from the bottom plate 21, and the gear shifting module is simple and compact in structure and can realize smooth switching between an automatic mode and a manual mode.

Specifically, gear shifting module 3 still includes transmission gear group, and transmission module is including screw rod 41 and the nut 42 of mutually supporting, and motor element 31 is connected with the one end of screw rod 41 through transmission gear group and is used for driving screw rod 41 to rotate, and nut 42 sets up on bottom plate 21, and motor element 31 driving screw rod 41 rotates in order to drive nut 42 and bottom plate 21 and remove, and its simple structure, compactness can make the motion of cavity 2 more steady.

In this embodiment, the gear switching module 3 includes a motor assembly 31, a gear lifting mechanism 32 and a transmission gear set, the motor assembly 31 is fixedly mounted on the inner wall of the machine body 1 and does not move back and forth along with the cavity 2, the output end of the motor assembly 31 is respectively connected with the gear lifting mechanism 32 and the transmission gear set, the other ends of the gear lifting mechanism 32 and the transmission gear set are respectively connected with one end of a screw rod 41, wherein the transmission module includes a screw rod 41 and a nut 42 which are matched with each other, and the nut 42 is fixedly disposed on the bottom plate 21. In the operation and use process of the dishwasher, firstly, the motor assembly 31 drives the transmission module to ascend and descend through the gear elevating mechanism 32 so as to enable the transmission module to be connected with the bottom plate 21 or to enable the transmission module to be disconnected with the bottom plate 21, after the gear switching of the dishwasher is finished, the motor assembly 31 drives the screw rod 41 to rotate and work through the transmission gear set, then the nut 42 is driven to move back and forth, and the cavity 2 and the door body are driven to move back and forth along the screw rod 41 through the action of the nut 42 so as to open or close the door body.

Preferably, the motor assembly 31 is connected with the other end of the screw rod 41 through the gear lifting mechanism 32, and when the motor assembly 31 drives 32 the screw rod 41 to lift through the gear lifting mechanism, the screw rod 41 is engaged with the nut 42; when the motor assembly 31 drives the screw rod 41 to descend through the gear lifting mechanism 32, the screw rod 41 is separated from the nut 42, the design is reasonable, the structure is compact, and the nut 42 and the screw rod 41 can be separated and engaged at any time conveniently.

Preferably, a connecting member 43 is further included, and the nut 42 is fixed to the bottom of the base plate 21 by the connecting member 43, which enables the nut 42 to be firmly mounted on the base plate 21.

Furthermore, a positioning element 44 is disposed at one end of the screw 41 away from the transmission gear set, and the positioning element 44 is mounted on the machine body 1, and the positioning element 44 is matched with the bottom plate 21 to limit the forward and backward movement of the nut 42, so that the structure is simple, and the movement stroke of the nut 42 can be effectively controlled.

In this embodiment, the cross section of the nut 42 is semicircular, the nut 42 is opened at an end near the screw rod 41, and the screw rod 41 enters from the opened end of the nut 42 until the screw rod 41 engages with the nut 42. As shown in fig. 3, the screw 41 may be in an automatic mode of the X-range or in a manual mode of being lowered to the Y-range, and when the screw 41 is in the Y-range, the user may manually perform opening and closing of the dishwasher door. When a user needs to start the automatic mode, the motor assembly 31 drives the gear lifting mechanism 32 to drive the screw rod 41 to integrally ascend to the gear I, when the screw rod 41 is meshed with the nut 42, the motor assembly 31 drives the transmission gear set to rotate so as to drive the screw rod 41 to perform rotary motion, the nut 42 is driven to move back and forth through the rotary motion of the screw rod 41, the cavity 2 and the door body are driven to move back and forth along the screw rod 41, when the moving stroke of the forward movement of the nut 42 reaches the positioning piece 44, the motor assembly 31 stops moving, and the door opening procedure is completed. Likewise, the door closing procedure is the reverse of the door opening procedure. In the running process of the dishwasher in the automatic mode in the X gear, when the power is suddenly cut off or the force is suddenly increased due to the fact that the speed is artificially changed, the control module can control the motor assembly 31 to drive the screw 41 to descend to the Y gear, and the screw 41 is separated from the nut 42 to enter the manual mode. The dishwasher of the present embodiment can be switched from the automatic mode to the manual mode at any time, and from the manual mode to the automatic mode, in order to make the screw 41 and the nut 42 more effectively engaged, the switching from the manual mode to the automatic mode can be completed when the chamber 2 is at the extreme position, that is, the chamber 2 is at the fully opened state or the fully closed state. When the motor assembly 31 of this embodiment is configured as one motor, the screw 41 is driven by a single motor to rotate and lift, and certainly, two motors may be further configured, wherein one motor drives the screw 41 to rotate and the other motor drives the screw 41 to lift.

Furthermore, the middle position of the bottom plate 21 protrudes upwards to form a sliding groove 22 extending in the front-rear direction, and the transmission module is arranged in the sliding groove 22.

Specifically, the guide rails 23 are respectively arranged on two sides of the cavity 2, and two sides of the bottom plate 21 are respectively connected with the guide rails 23 in a sliding manner, so that the cavity 2 can be conveniently opened or closed.

Particularly, the front end of the guide rail 23 is provided with the limit plate 24, which has a simple structure and can effectively control the movement stroke of the cavity 2.

In this embodiment, the positioning element 44 is installed on the machine body 1 and disposed below the sliding slot 22, when the positioning element is used for controlling the movement stroke of the nut 42, the motor assembly 31 drives the screw rod 41 to rotate so as to drive the nut 42 to move back and forth, and further drive the cavity 2 and the door body to move back and forth along the screw rod 41, when the nut 42 moves forward, the bottom plate 21 can be prevented from being blocked by the positioning element 44 during movement through the sliding slot 22, but when the movement stroke of the nut 42 disposed in the sliding slot 22 reaches the positioning element 44, the motor assembly 31 can stop working. The opening and closing door of the dishwasher of the embodiment has two modes, namely an automatic mode and a manual mode, and in the manual mode, the dishwasher mainly realizes the opening or closing of the cavity 2 through the guide rail 23; after the manual mode is switched to the automatic mode, the dish washer drives the nut 42 to move mainly through the action of the screw rod 41, and then drives the cavity 2 to move back and forth along the guide rail 23 so as to open or close the cavity 2. The dishwasher realizes the opening and closing of the dishwasher cavity 2 through the rotation of the screw rod 41, the running speed of the dishwasher is more stable, the collision risk of tableware is further reduced, and the use experience of a user is also increased.
