Also, the accommodating chamber 51 is located downstream of the liquid in the washing chamber 11, and the water inlet 53 may communicate with the washing chamber 11. Thus, when residual water is accumulated in the washing chamber 11, the residual water can enter the downstream accommodating chamber 51 through the water inlet 53, and the residual water is accommodated in the accommodating chamber 51.
The water removing device 50 further comprises a water removing assembly 55, the water removing assembly 55 is arranged in the accommodating cavity 51 in a lifting manner along the first direction, and the water removing assembly 55 has a water receiving state and a water discharging state. When in a water collection state, the water removal assembly 55 moves along a direction from the top end to the bottom end, and a water passing opening 552 is formed in the water storage assembly, and the water passing opening 552 allows the liquid in the accommodating cavity 51 to flow to one side of the water removal assembly 55 facing the top end; in the drainage state, the water outlet 552 is closed, and the water removal assembly 55 moves in a direction from the bottom end to the top end to reach the water outlet 54.
In this way, the liftable water removal assembly 55 is disposed in the accommodating cavity 51, when the water removal assembly 55 is in a water collection state, and when the water removal assembly 55 moves from the top end to the bottom end of the housing 52, the water passing opening 552 on the water removal assembly 55 is opened, the liquid in the accommodating cavity 51 can flow to one side of the water removal assembly 55 facing the top end through the water passing opening 552, that is, in the view angle of fig. 1, when the water removal assembly 55 moves downward, the liquid in the accommodating cavity 51 can flow to the upper side of the water removal assembly 55 through the water passing opening 552, so that the liquid in the accommodating cavity 51 is all transferred to the upper side of the water removal assembly 55 facing the top end. Then, the water removal module 55 is switched to a drainage state, at this time, the water outlet 552 on the water removal module 55 is closed, and the water removal module 55 moves along the direction from the bottom end to the top end, so as to drive the liquid on the top end side of the water removal module 55 to move towards the top end. In the process that the water removal assembly 55 moves towards the top end, liquid above the water removal assembly 55 gradually approaches the water outlet 54, when the liquid level of the liquid reaches the position of the water outlet 54, the liquid carried by the water removal assembly 55 can flow out of the accommodating cavity 51 through the water outlet 54, the water removal assembly 55 gradually rises along with the liquid flowing out of the water outlet 54, the liquid level of the liquid is gradually increased, the liquid level of the liquid at least reaches the position of the water outlet 54 all the time, until the water removal assembly 55 moves to the position of the water outlet 54, the liquid above the water removal assembly 55 completely flows out of the water outlet 54, and the work of eliminating residual water can be completed.

Optionally, a water outlet 54 is opened on a side wall of the top end of the housing 52 in a second direction intersecting the first direction. Thus, when the water removal module 55 is carrying liquid and rising, if the liquid level reaches the top side wall of the water outlet 54, the liquid will flow out of the water outlet 54 under its own weight.
Optionally, the periphery of the water removal assembly 55 abuts against the inner wall of the accommodating cavity 51 in a sealing manner, and the water removal assembly 55 can be lifted and lowered in the accommodating cavity 51. Thus, a bearing space can be formed between the surface of the water removal assembly 55 facing the top end and the inner wall of the accommodating cavity 51, and the bearing space is lifted along with the movement of the water removal assembly 55, so that the liquid entering the bearing space can be driven to rise to the water outlet 54 and then be discharged. Moreover, because the water removal assembly 55 is always abutted against the inner wall of the accommodating cavity 51, the liquid entering the bearing space can be prevented from leaking, so that all the liquid in the accommodating cavity 51 is driven to be discharged, and the liquid discharge effect is improved.
The water removal assembly 55 comprises a movable plug 551 and a one-way plate 553, the movable plug 551 is movably arranged in the accommodating cavity 51 along a first direction, and the periphery of the movable plug 551 is kept in contact with the inner wall of the accommodating cavity 51; the movable plug 551 is provided with a water gap 552, and the one-way plate 553 is arranged at the water gap 552 and can be movably arranged relative to the movable plug 551. In the water collection state, the one-way plate 553 moves relative to the piston to open the water gap 552; in the draining state, the check plate 553 moves relative to the movable plug 551 to close the water gap 552. Thus, the movable plug 551 and the one-way plate 553 cooperate to carry the liquid in the accommodating cavity 51 to the water outlet 54. Specifically, the movable plug 551 is abutted against the inner wall of the accommodating cavity 51, a bearing space can be formed between one side of the movable plug 551 facing the top end of the housing 52 and the inner wall of the accommodating cavity 51, the bearing space is lifted along with the movement of the movable plug 551, and the water passing opening 552 on the movable plug 551 is opened or closed through the position adjustment of the one-way piece 553, so that the water passing opening 552 can be opened first to allow all liquid in the accommodating cavity 51 to enter the bearing space, then the water passing opening 552 is closed through the one-way piece 553, and then the movable plug 551 is lifted, so that the liquid in the bearing space can be driven to rise to the water outlet 54, and then the liquid is discharged out of the dishwasher 100. Optionally, movable plug 551 is a rubber plug.
In the embodiment, the one-way plate 553 is movably covered on the side of the movable plug 551 facing the top end; in the water collecting state, the movable plug 551 moves along the direction from the top end to the bottom end, the one-way sheet 553 moves away from the movable plug 551 under the impact of the liquid in the containing cavity and opens the water passing opening 552; that is, when the movable plug 551 moves toward the bottom end, the one-way plate 553 located on the side of the movable plug 551 facing the top end receives the upward impact force of the liquid, and moves away from the movable plug 551, so as to open the previously covered water passing opening 552, allow the liquid to flow from the water passing opening 552 to the side of the movable plug 551 facing the top end, and allow the liquid to flow into the carrying space above the piston.
In the drainage state, the movable plug 551 moves in a direction from the bottom end to the top end, and the one-way piece 553 is pressed by the liquid from the movable plug 551 toward the top end to keep abutting against the movable plug 551 and close the water gap 552; that is, when the movable plug 551 moves towards the bottom end to the bottommost portion of the accommodating cavity 51, all the liquid in the accommodating cavity 51 flows into the bearing cavity through the water gap 552, at this time, the movable plug 551 descends to the limit position and does not descend, the one-way plate 553 no longer receives the upward impact force of the liquid, and the one-way plate 553 can fall back onto the movable plug 551 under the action of its own gravity and close the water gap 552; then, the moving direction of the movable plug 551 is changed to drive the movable plug 551 to move towards the top end, and at this time, the one-way sheet 553 at the bottom of the liquid is pressed onto the movable plug 551 under the gravity action of the liquid, so that the water gap 552 can be always kept sealed, and the movable plug 551 is allowed to convey the liquid to the water outlet 54 completely, thereby completing the drainage work.
Thus, the interaction between the one-way plate 553 and the liquid when the movable plug 551 moves is used to drive the one-way plate 553 to move, and further, the water gap 552 is opened or closed, and other structures are not needed to control the one-way plate 553, so that the whole structure is simple.
Alternatively, the unidirectional sheet 553 may have a density in the range of 1g/cm3-1.8g/cm3So that the density of the one-way blade 553 is greater than that of water, when the movable plug 551 is kept still in the accommodating cavity, the one-way blade 553 can sink to close the water gap 552 in the residual water under the action of its own weight, so as to subsequently lift the residual water to the water outlet 54 by the movable plug 551.
Referring to fig. 2-3, further, the residual water removing device 50 further includes a limiting member 56, the limiting member 56 is disposed on one side of the movable plug 551 facing the top end, the limiting member 56 defines a limiting space 563 communicating with the accommodating cavity and the water passing opening 552, the one-way plate 553 is movably disposed in the limiting space 563 along a first direction, and the limiting member 56 is blocked around the one-way plate 553 along a second direction intersecting the first direction, so that the limiting member 56 blocks around the one-way plate 553 along the second direction, the one-way plate 553 is prevented from being washed away by the water flow, and the one-way plate 553 is allowed to freely move in the first direction to perform actions of closing and opening the water passing opening 552. And, the limiting space 563 is connected to the containing cavity, allowing the liquid to freely pass through the limiting member 56, and the limiting member 56 does not affect the liquid flowing from the water passing opening 552 to or from the movable plug 551 to the top of the top end.
Specifically, the limiting member 56 includes a plurality of limiting rods 561, the limiting rods 561 are disposed on the movable plug 551 at intervals around the one-way plate 553, and enclose to form a limiting space 563, which is equivalent to a gap allowing the liquid to flow to the water passing opening 552 or flow out from the water passing opening 552 is formed between the limiting rods 561, and the limiting rods 561 surround the one-way plate 553 to limit the one-way plate 553, so as to prevent the one-way plate 553 from being washed away by the liquid.
More specifically, the residual water remover 50 further comprises a driving member 57, wherein the driving member 57 is connected to the limiting member 56, and applies a driving force to the limiting member 56 to move up and down along a first direction, that is, the driving member 57 drives the limiting member 56 and the movable plug 551 to move up and down, so as to perform the residual water removing operation. Optionally, the limiting member 56 is a clamping jaw clamped on the movable plug 551, and the clamping jaw is not only used for limiting the one-way plate 553, but also used for clamping the movable plug 551, so that the movable plug 551 is clamped by the clamping jaw and then lifted together with the clamping jaw to drive the movable plug 551 to move.
Alternatively, the water remainder remover 50 is connected between the inner container 10 and the drain assembly 74, the water inlet 53 may communicate with the washing chamber 11, and the water outlet 54 communicates with the drain assembly 74. When the residual water removing operation is performed, the residual water in the washing chamber 11 can enter the residual water removing device 50 through the water inlet 53 under the action of its own weight, and then the residual water entering the residual water removing device 50 can be discharged from the water outlet 54 under the action of the water removing assembly 55, and then be collected into the water discharging assembly 74, and finally be discharged out of the dishwasher 100.
