Referring to fig. 1 to 8, a bowl basket assembly 10 according to an embodiment of the present invention includes a bowl basket 11, a rail assembly 12, a drawing-out mechanism 13 and a lifting mechanism 14, the bowl basket 11 is formed with a first connecting portion 112, the rail assembly 12 is installed on a side surface of the bowl basket 11, the drawing-out mechanism 13 includes a drawing-out motor 131 and a moving block 132, the moving block 132 is formed with a second connecting portion 133 engaged with the first connecting portion 112, the drawing-out motor 131 is connected to the moving block 132 and is configured to drive the moving block 132 to move forward and backward, the first connecting portion 112 is engaged with the second connecting portion 133 to enable the bowl basket 11 and the rail assembly 12 to move forward and backward along with the moving block 132, the lifting mechanism 14 includes a lifting motor 141 and a link assembly 15, the lifting motor 141 and the drawing-out motor 131 are disposed at an interval, the lifting motor 141 is connected to the rail assembly 12 through the link assembly, the first connecting portion 112 can be disengaged from the second connecting portion 133 when the bowl basket 11 is raised.

According to the bowl and basket assembly 10, the bowl basket 11 can move back and forth and up and down under the action of the leading-out mechanism 13 and the lifting mechanism 14, when a user needs to put tableware into the bowl basket 11 or take the tableware out of the bowl basket 11, the bowl basket 11 can firstly slide forwards to move out of an unoccupied position in the upper space and then move upwards to a position convenient for the user to operate, so that the user can put in and take out the tableware more conveniently, and the user experience is improved.

The bowl and basket assembly 10 of the present embodiment is applicable to a washing appliance 100. The bowl basket 11 may be a lower bowl basket 102 of the washing appliance 100, and the opening of the bowl basket 11 faces upward for a user to put in and take out dishes. The washing appliance 100 is for example a dishwasher.

Specifically, a rail assembly 12, a drawing mechanism 13 and a lifting mechanism 14 are respectively arranged on two sides of the bowl basket 11. Therefore, the bowl basket 11 is balanced in stress, and the processes of the bowl basket 11 moving back and forth and moving up and down are more stable.

Referring to fig. 4 and 8, in some embodiments, the second connecting portion 133 is formed with a groove 1332, and the first connecting portion 112 is disposed in the groove 1332 to enable the bowl basket 11 to slide back and forth along with the moving block 132. In this way, the first connecting portion 112 can be easily separated from the second connecting portion 133 when the bowl basket 11 is lifted, so that the bowl basket 11 can be lifted away from the moving block 132.

Specifically, the first connecting portion 112 is an L-shaped structure disposed on the outer side of the bowl basket 11, one side of the L-shaped structure is fixed on the outer side of the bowl basket 11, and the other side of the L-shaped structure extends out of the outer side of the bowl basket 11 and is used for being matched with the groove 1332, when the bowl basket 11 moves back and forth, the other side of the L-shaped structure is clamped in the groove 1332, and when the bowl basket 11 moves up and down, the other side of the L-shaped structure is disengaged from the groove 1332 or enters the groove 1332. This L-shaped configuration allows the first connection portion 112 to flexibly snap into and out of the recess 1332.

In some embodiments, the leading-out mechanism 13 includes a lead screw 134, the moving block 132 is movably disposed on the lead screw 134, the leading-out motor 131 is connected to the lead screw 134 and is used for driving the lead screw 134 to rotate, and the moving block 132 can move back and forth along the axial direction of the lead screw 134 when the lead screw 134 rotates. In this way, the leading-out motor 131 drives the moving block 132 to move back and forth by a simple structure, and the moving block 132 moves along the lead screw 134 so that the moving track of the moving block 132 is stable, thereby stabilizing the process of moving the bowl basket 11 back and forth.

Specifically, an external thread is formed on the surface of the lead screw 134, an internal thread matched with the external thread is formed on the moving block 132, and when the lead-out motor 131 drives the lead screw 134 to rotate, the external thread rotates and enables the internal thread to rotate along the external thread so that the moving block 132 moves back and forth along the axial direction of the lead screw 134.

In some embodiments, the leading-out mechanism 13 includes a supporting plate 135, a leading-out shaft 136 and a sliding bearing 137, the lead screw 134 and the leading-out shaft 136 are arranged in parallel and spaced, the sliding bearing 137 is slidably arranged on the leading-out shaft 136, the sliding bearing 137 is connected with the moving block 132, one end of the lead screw 134 is rotatably mounted on the supporting plate 135, and one end of the leading-out shaft 136 is fixed on the supporting plate 135. In this way, the position of the second connecting portion 133 relative to the screw 134 is limited by the leading-out shaft 136 and the sliding bearing 137, so that the second connecting portion 133 is prevented from rotating around the screw 134, and the process of moving the bowl basket 11 back and forth is smoother.

Specifically, the groove 1332 formed in the second connecting portion 133 is located at the top of the moving block 132, and the opening of the groove 1332 is always kept upward. When the screw rod 134 rotates, the moving block 132 tends to rotate around the screw rod 134 under the action of friction between the external threads and the internal threads, and the opening direction of the groove 1332 can be changed, so that the first connecting portion 112 cannot be well clamped in the groove 1332, which may cause the bowl basket 11 not to normally move back and forth. Because the leading-out shaft 136 is parallel to the screw rod 134 and the relative position is fixed, the sliding bearing 137 is connected with the leading-out shaft 136 and the moving block 132, so that the opening of the groove 1332 is kept upward all the time, the first connecting part 112 can be well clamped in the groove 1332 in the forward and backward moving process of the bowl basket 11, and the forward and backward moving process of the bowl basket 11 is smoother.

One end of the screw 134 may be rotatably mounted to the support plate 135 by a rolling bearing.

In some embodiments, the extraction mechanism 13 includes a connection joint 138, and the connection joint 138 connects the output shaft of the extraction motor 131 and the lead screw 134. In this way, the screw 134 is more stably rotated.

Referring to fig. 5-7, in some embodiments, the link assembly 15 includes a rotating shaft 151, a first connecting member 152 and a second connecting member 153, the first connecting member 152 connects the output shaft of the lifting motor 141 and the rotating shaft 151, the second connecting member 153 connects the rotating shaft 151 and the guide rail assembly 12, and the lifting motor 141 is configured to drive the first connecting member 152 to rotate around the rotating shaft 151 and drive the second connecting member 153 to rotate, so that the second connecting member 153 drives the guide rail assembly 12 and the bowl basket 11 to ascend or descend. Thus, the bowl basket 11 is raised or lowered with a simpler structure.

Specifically, the rotating shaft 151 includes a connecting section 1511 with a square cross section, the first connecting part 152 and the second connecting part 153 are respectively provided with a first connecting hole 1522 and a second connecting hole 1532 with shapes corresponding to the cross section of the connecting section 1511, and the connecting section 1511 penetrates through the first connecting hole 1522 and the second connecting hole 1532, so that when the first connecting part 152 rotates around the rotating shaft 151, the rotating shaft 151 can drive the second connecting part 153 to rotate around the rotating shaft 151. Of course, in other embodiments, the cross section of the connection end is not limited to a square shape, and may be a shape such as a triangle, a pentagon, a hexagon, or other polygons that can ensure the rotation of the rotation shaft 151, the first connection member 152, and the second connection member 153 simultaneously.

Further, the second link 153 rotates from bottom to top about the rotation shaft 151 to move the bowl basket 11 upward, and the second link 153 rotates from top to bottom about the rotation shaft 151 to move the bowl basket 11 downward. Therefore, in the process of moving the bowl basket 11 up and down, the distance from the bowl basket 11 to the user is gradually reduced, the user can put in and take out tableware conveniently, and the user experience is improved; the bowl basket 11 gradually approaches the inner container 20 of the washing appliance 100 during the downward movement process, so as to reduce the moving distance required during the forward and backward movement of the washing appliance 100.

In some embodiments, first link 152 is rotatably coupled to the output shaft of lift motor 141 and second link 153 is rotatably coupled to rail assembly 12. Thus, the distance between the first connecting piece 152 and the output shaft of the lifting motor 141 is constant and the relative angle is variable, and the distance between the second connecting piece 153 and the guide rail assembly 12 is constant and the relative angle is variable, so that when the first connecting piece 152 and the second connecting piece 153 rotate, the opening of the bowl basket 11 faces upwards all the time, the bowl basket 11 is kept stable, and tableware in the bowl basket 11 can be stably placed in the bowl basket 11.

In some embodiments, the lifting mechanism 14 includes a fixing plate 142, a rotating shaft 151 rotatably penetrates through the fixing plate 142, a first connecting member 152 and a second connecting member 153 are respectively disposed on opposite sides of the fixing plate 142, and the lifting motor 141 and the first connecting member 152 are disposed on the same side of the fixing plate 142. In this manner, when the bowl and basket assembly 10 is applied to the washing appliance 100, the lifting mechanism 14 can be assembled to the washing appliance 100 by using the fixing plate 142, which facilitates the installation of the bowl and basket assembly 10.

Specifically, the rotating shaft 151 includes a head portion 1512 and a shaft portion 1513, the shaft portion 1513 is rotatably disposed through the fixing plate 142, and the head portion 1512 abuts against a surface of the fixing plate 142. The rod portion 1513 includes a cylindrical section 1514 having a circular cross section and two connecting sections 1511 provided at both ends of the cylindrical section 1514, and the first link 152 and the second link 153 are connected to the two connecting sections 1511 at both ends of the cylindrical section 1514, respectively. The cylindrical section 1514 is disposed in a through hole formed in the mounting plate 142.

Further, the washing appliance 100 comprises a liner 20, when the bowl and basket assembly 10 is applied to the washing appliance 100, the fixing plate 142 can be fixedly mounted on the outer surface of the liner 20, the connecting rod assembly 15 comprises a first gasket 154 disposed between the inner surface of the liner 20 and the second connecting member 153 and a second gasket 155 disposed between the fixing plate 142 and the first connecting member 152, the rod portion 1513 sequentially penetrates through the second connecting member 153, the first gasket 154, the sidewall of the liner 20, the fixing plate 142, the second gasket 155 and the first connecting member 152 from the inner side of the liner 20 to the outer side of the liner 20, wherein the connecting section 1511 near the head 1512 penetrates through the second connecting member 153, and the connecting section 1511 far from the head 1512 penetrates through the first connecting member 152. Therefore, the friction between the first connecting piece 152 and the fixing plate 142 and the friction between the second connecting piece 153 and the inner container 20 can be reduced, and the lifting motor 141 drives the bowl basket 11 to ascend in a labor-saving manner.

Furthermore, a screw hole 1515 is formed at an end of the shaft portion 1513 away from the head 1512, and a screw passes through the screw hole 1515 and abuts against the surface of the first connecting member 152, so that the connection between the parts of the connecting rod assembly 15 is firmer.

It can be understood that when the bowl and basket assembly 10 is applied to the washing appliance 100, the lifting motor 141, the fixing plate 142, the first connector 152 and the second gasket 155 are located outside the inner container 20. Thus, the lifting motor 141, the fixing plate 142, the first connecting member 152 and the second gasket 155 are well protected from being corroded by the humid environment in the inner container 20, which is helpful for prolonging the service life of the lifting mechanism 14.

In some embodiments, the linkage assembly 15 includes a third link 156, one end of the third link 156 is rotatably connected to the rail assembly 12, the other end of the third link 156 is rotatably connected to the fixing plate 142, and the third link 156 and the second link 153 are located on the same side of the fixing plate 142.

In this way, the second connector 153 and the third connector 156 connect the fixing plate 142 and the rail assembly 12, so that the bowl basket 11 is stressed more evenly, and the opening of the bowl basket 11 is kept upward.

Specifically, the second connecting member 153 rotates around the rotating shaft 151 under the driving of the lifting motor 141, and drives the rail assembly 12 and the bowl basket 11 to ascend or descend, the third connecting member 156 also rotates synchronously with the second connecting member 153 under the driving of the rail assembly 12, and since the length of the third connecting member 156 is fixed, the third connecting member 156 has a pulling force on the bowl basket 11, which can share part of the gravity of the bowl basket 11, and reduce the stress of the second connecting member 153.

The third connecting member 156 is structurally symmetrical to the second connecting member 153, and the connection manner of the third connecting member 156 and the fixing plate 142 is the same as that of the second connecting member 153 and the fixing plate 142, which is not described herein again.

In the embodiment of the present invention, the second connector 153 and the third connector 156 are two semicircular plates symmetrically disposed. In this way, the second and

third connection members

153 and 156 are more uniformly stressed. Of course, in other embodiments, the positional relationship and the shape of the second connection member 153 and the third connection member 156 may be other, and are not limited herein.

The connection of the third link 156 to the rail assembly 12 and the connection of the second link 153 to the rail assembly 12 are arranged along the length of the rail assembly 12 such that the opening of the bowl basket 11 is maintained upward.

In some embodiments, the lift mechanism 14 includes a damping device 143, and the damping device 143 is rotatably coupled to the first link 152. Therefore, the damping device 143 makes the ascending and descending processes of the bowl basket 11 more stable, and avoids the damage of the tableware collision in the bowl basket 11 or the bowl basket 11 caused by the over-fast moving speed of the bowl basket 11 and the over-high acceleration of the bowl basket 11 during the movement.

In particular, the damping device 143 may be an elastic member. The damping device 143 has one end rotatably connected to the first connecting member 152 and the other end rotatably connected to the fixing plate 142. When the bowl and basket assembly 10 is applied to the washing appliance 100, the other end of the damping device 143 can also be rotatably connected to the side wall of the inner container 20 of the washing appliance 100. Thus, one end of the damping device 143 is fixed, and the other end is connected to the first connector 152. The first link 152 is subjected to a pulling force of the damping device 143, which may assist the lifting of the bowl basket 11. When the first connecting piece 152 rotates downwards around the rotating shaft 151, the first connecting piece 152 is pulled by the damping device 143, so that the rotating speed of the first connecting piece 152 can be reduced, the bowl basket 11 is prevented from moving too fast, and the up-and-down movement process of the bowl basket 11 is more stable; when the first link 152 rotates upward about the rotation shaft 151, the first link 152 is pulled by the damping device 143, so that the bowl basket 11 can be assisted to be lifted. The damping device 143 can also reduce the inertia, so that when the lifting motor 141 stops, the first connecting member 152 can stop rotating in time and stop the bowl basket 11, thereby controlling the position of the bowl basket 11 more accurately.

In the embodiment of the present invention, the damper 143 is a gas spring, but in other embodiments, the damper 143 may be other devices.

The elevating mechanism 14 includes a fixing screw 144 and a connecting screw 145, the connecting screw 145 includes a block 1452 and a first connecting post 1454 and a second connecting post 1456 provided at both ends of the block 1452, the first connecting post 1454 is formed with an external thread, the second connecting post 1456 is formed with an internal thread, and the fixing screw 144 is engaged with the internal thread.

One end of the damping device 143 is rotatably connected to the first connector 152 via the fixing screw 144 and the connecting screw 145, and the other end is rotatably connected to the fixing plate 142 or the sidewall of the inner container 20 of the washing appliance 100 via the fixing screw 144 and the connecting screw 145. The first connecting column 1454 is fixedly connected to the first connecting member 152, the second connecting column 1456 is rotatably inserted into one end of the damping device 143, the screw of the fixing screw 144 is engaged with the internal thread of the second connecting column 1456 to enable the nut to abut against the surface of the damping device 143, one end of the damping device 143 is located between the nut and the end surface of the cushion 1452, and the cushion 1452 is located between the first connecting member 152 and the damping device 143.
