When the door 200 is switched to open or close the opening 111, the driving transmission assembly 350 drives the piston assembly 340 to move in the drainage channel 310, so as to guide water in the drainage port 120 to flow into the drainage channel 310 from the water inlet 320 and/or discharge water in the drainage channel 310 out of the body 100 through the water outlet 330.

In the present embodiment, the shape of the whole body of the body 100 may be selected and designed according to actual use requirements, for example, the whole body of the body 100 is in a square cabinet shape, a cylindrical shape, and the like, and is not limited herein. The water tank 110 is used for placing bowls, and the water tank 110 can also be internally provided with a detachable bowl basket for placing the bowls to be cleaned in a classified manner. A spray device is provided in the water tank 110 to wash dishes placed in the water tank 110. In some embodiments, a drying device may be further disposed in the body 100 for drying, sterilizing, etc. the washed dishes. The door body 200 is disposed at the opening 111 of the body 100, and the door body 200 and the body 100 may be in sliding connection, rotating connection, or the like, so as to realize sliding or rotating to open and close the opening 111. When the door 200 opens the opening 111, the user can take out or put the dishes into the sink 110 through the opening 111. When the door 200 is closed, dust can be prevented from entering the water tank 110, and water can be prevented from overflowing to the outside of the body 100 when the dishwasher is in operation.

The drainage channel 310 may be defined by the interior of the fuselage 100, or the drainage channel 310 may be defined by another structure such as a pump body or sleeve 370. The drainage device 300 may be disposed inside the body 100 or outside the body 100. The water inlet 320 and the water outlet 120 may be communicated with each other through a water inlet pipe 400. The water outlet 330 may be communicated with a drain pipe of the dishwasher through the water outlet pipe 500, or the water of the water outlet pipe 500 may be directly discharged to the outside of the body 100. It can be understood that the side of the drainage channel 310 away from the water inlet 320 and the water outlet 330 is provided with an opening 3711 communicated with the outside air so that the piston assembly 340 can reciprocate in the drainage channel 310, and the side of the drainage channel 310 close to the water inlet 320 of the piston assembly 340 forms a vacuum negative pressure to suck the water in the water outlet 120 from the water inlet 320 into the drainage channel 310 and then to be discharged out of the body 100 through the water outlet 330.

There are various structures for sucking water from the water inlet port 320 into the drainage channel 310 through the piston assembly 340 and discharging water in the drainage channel 310 through the water outlet port 330. For example, in one embodiment, the water inlet 320 and the water outlet 330 are disposed on the same side of the piston assembly 340, the side of the diversion channel 310 away from the water inlet 320 and the water outlet 330 is disposed as an opening 3711, and a check valve is disposed at each of the water inlet 320 and the water outlet 330. When the piston assembly 340 moves towards the side far away from the water inlet 320 and the water outlet 330, a vacuum negative pressure is formed at the side of the drainage channel 310 close to the water inlet 320, the one-way valve at the water inlet 320 can realize water inlet, the one-way valve at the water outlet 330 cannot realize water inlet, so that water in the water outlet 120 is sucked into the drainage channel 310 from the water inlet 320, and when the piston assembly 340 moves towards the side close to the water inlet 320 and the water outlet 330, the one-way valve at the water inlet 320 cannot realize water outlet, the one-way valve at the water outlet 330 can realize water outlet, so that sewage in the drainage channel 310 is pressed towards the water outlet 330 and is discharged out of the machine body 100 through the water outlet 330. The combined piston assembly 340 is connected to the door 200 through the transmission assembly 350, when the door 200 is switched to the open state, the transmission assembly 350 is driven to drive the piston assembly 340 to move toward one side in the drainage channel 310 to guide the water in the drainage port 120 to flow into the drainage channel 310 from the water inlet 320/discharge the water in the drainage channel 310 to the outside of the body 100 through the water outlet 330, and when the door 200 is switched to the closed state, the transmission assembly 350 is driven to drive the piston assembly 340 to move toward the other side in the drainage channel 310 to discharge the water in the drainage channel 310 to the outside of the body 100 through the water outlet 330/guide the water in the drainage port 120 to flow into the drainage channel 310 from the water inlet 320.

In another embodiment, the water inlet 320 and the water outlet 330 are located on both sides of the piston head 342 of the piston assembly 340, i.e., the piston assembly 340 reciprocates in the diversion channel 310 between the water inlet 320 and the water outlet 330, and a one-way valve is provided on the piston and at the water inlet 320. So, similar to the pressurized-water principle of the water pump, when the piston assembly 340 moves towards the side far away from the water inlet 320, the check valve on the piston is closed, the check valve at the water inlet 320 is opened, then vacuum negative pressure is formed at the side of the drainage channel 310 close to the water inlet 320, the water at the water outlet 120 is sucked into the drainage channel 310 from the water inlet 320, and when the piston assembly 340 moves towards the side close to the water inlet 320, the check valve on the piston is opened, the check valve at the water inlet 320 is closed, the sewage in the drainage channel 310 flows to the water outlet 330 through the piston, so as to discharge the sewage of the drainage channel 310. The combined piston assembly 340 is connected to the door 200 through the transmission assembly 350, when the door 200 is switched to the open state, the transmission assembly 350 is driven to drive the piston assembly 340 to move toward one side in the drainage channel 310 to guide the water in the drainage port 120 to flow into the drainage channel 310 from the water inlet 320/discharge the water in the drainage channel 310 to the outside of the body 100 through the water outlet 330, and when the door 200 is switched to the closed state, the transmission assembly 350 is driven to drive the piston assembly 340 to move toward the other side in the drainage channel 310 to discharge the water in the drainage channel 310 to the outside of the body 100 through the water outlet 330/guide the water in the drainage port 120 to flow into the drainage channel 310 from the water inlet 320.

In yet another embodiment, the water inlet 320 and the water outlet 330 may be spaced on the moving track of the piston assembly 340. In this way, when the piston assembly 340 moves from the side of the water inlet 320 to the side of the water outlet 330, the sewage at the water outlet 120 is introduced into the drainage channel 310 through the water inlet 320, and when the piston assembly 340 continues to move to pass through the water outlet 330, the sewage in the drainage channel 310 is discharged through the water outlet 330. Thus, in combination with the piston assembly 340 connected to the door 200 through the transmission assembly 350, when the door 200 is switched to the open state or the closed state, the transmission assembly 350 is driven to drive the piston assembly 340 to move toward one side in the drainage channel 310, so as to guide the water in the drainage outlet 120 to flow into the drainage channel 310 from the water inlet 320, and simultaneously discharge the water in the drainage channel 310 out of the body 100 through the water outlet 330. Of course, there are many similar structures that are implemented by the piston assembly 340 to introduce the water from the water outlet 120 into the drainage channel 310 through the water inlet 320 and discharge the water out of the body 100 through the water outlet 330, which are not listed here.

The transmission assembly 350 may be embodied as a link structure, a rack and pinion structure, a cable 351 roller structure, and the like. The corresponding transmission assembly 350 can be selected according to the switching mode of opening and closing the switch door and the position relationship of the switch door and the piston assembly 340, and only the opening or closing movement of the switch door can be converted into the movement of the piston assembly 340 in the drainage channel 310. The transmission assembly 350 may be fixedly connected with the door body 200 and the piston assembly 340, or detachably connected. It will be appreciated that the opening and closing motion of the switch door may be translated into reciprocating movement of the piston assembly 340 within the drain channel 310 by the transmission assembly 350. It is also possible to convert only the opening or closing motion of the opening and closing door into the movement of the piston assembly 340 toward one side in the drainage channel 310, and an elastic restoring member, a driving motor, and the like may be additionally provided to realize the movement of the piston assembly 340 toward the other side in the drainage channel 310.

When the door 200 is switched to the open or closed state, the transmission assembly 350 can be driven to drive the piston assembly 340 to move in the drainage channel 310, so that water in the drainage outlet 120 is guided to flow into the drainage channel 310 from the water inlet 320, and/or water in the drainage channel 310 is discharged out of the body 100 through the water outlet 330. Therefore, the switching between the opening state and the closing state of the door body 200 is skillfully utilized, the transmission component 350 drives the piston component 340 to convert the movement of the dishwasher during opening and closing the door into the reciprocating motion of the piston component 340, so that the sewage at the water outlet 120 is extracted, and the sewage is discharged out of the machine body 100. Overall structure is simple reliable, and design benefit need not to use other actuating mechanism, electrical components and electrical system control, effective reduce cost, and can realize the thorough drainage of dish washer through piston assembly 340 drainage, and then guarantees that dish washer drinking cup 140 can not leave the residual water, avoids producing the peculiar smell, breeds the bacterium scheduling problem.

In one embodiment, referring to fig. 2 to 5, the transmission assembly 350 includes a rope 351, one end of the rope 351 is connected to the piston assembly 340, and the other end is connected to the door body 200.

In this embodiment, the material of the rope 351 may be metal, such as steel, nylon, plastic or other materials, and may be selected according to the actual use requirement, which is not limited specifically herein. It will be appreciated that the cord 351 may be a rope, belt or other similar structure. The door 200 may be provided with a hook, so that the rope 351 is connected to the hook. Of course, it is also possible to attach a hook structure at the end of the rope 351 so that the rope 351 is hooked on the hook by the hook structure. The other end of the rope 351 is hooked with the piston assembly 340 by a hook or the like. In this way, the connection of the cable 351 to the transmission assembly 350 and the piston assembly 340 is made simpler and faster, and the connection is more stable and reliable. The cable 351 may also be secured to the door body 200 and the piston assembly 340 by other means, not illustrated. The piston assembly 340 and the door body 200 are in transmission connection through the rope 351, the structure is simple, the occupied space is small, the flexibility is good, the position can be adjusted at will, the requirement on the relative position relationship between the door body 200 and the piston assembly 340 is small, namely, the transmission can be realized through the rope 351 no matter the position relationship between the door body 200 and the piston assembly 340. In addition, by connecting the door body 200 with the piston assembly 340 through the rope 351, when the door body 200 opens the opening 111, a pulling force required for hovering the door body 200 can be provided through the piston assembly 340.

Further, as shown in fig. 3 and 5, the transmission assembly 350 further includes a first guide wheel 352, the first guide wheel 352 is rotatably connected to the body 100, the rope 351 includes a first segment 3511, one end of the first segment 3511 is connected to the piston assembly 340, and the other end of the first segment 3511 passes around and abuts against a winding surface of the first guide wheel 352, and an extending direction of the first segment 3511 is the same as an extending direction of the piston assembly 340.

In this embodiment, the first guide wheel 352 is pivoted to the body 100 through a rotation shaft, and the first guide wheel 352 can rotate circumferentially relative to the rotation shaft. The outer peripheral surface of the first guide pulley 352 forms a winding surface. In order to prevent the rope 351 from falling off the first guide wheel 352, an annular groove may be further provided on an outer circumferential surface of the first guide wheel 352 to limit the axial movement of the rope 351 along the first guide wheel 352. The first roller may be arranged such that the rope 351 changes its extension direction, for example such that the rope 351 changes its extension direction by 180 ° after passing the first roller. Thus, the structure is more compact. It will be appreciated that the direction of extension of the piston assembly 340 is also the direction of movement of the piston assembly 340. The extension direction of the first segment 3511 is identical to the extension direction of the piston assembly 340, and may be identical or have an error of not more than 5 degrees. So that the extending direction of the first section 3511 is consistent with the extending direction of the piston assembly 340, and the piston assembly 340 and the door body 200 are smoothly switched through the first guide wheel 352, that is, when the door body 200 is switched to open or close the opening 111, the rope 351 is pulled, so that the first section 3511 of the rope 351 drives the piston assembly 340 to translate along the moving direction of the piston assembly 340, and thus, the rope 351 can be prevented from generating a deflection force on the piston assembly 340, and further, the smooth and steady movement of the piston assembly 340 is ensured.

Based on the above embodiment, referring to fig. 3 and 5 again, the transmission assembly 350 further includes a second guide wheel 353, the second guide wheel 353 and the first guide wheel 352 are disposed in a staggered manner in the extending direction of the first segment 3511, the rope 351 further includes a second segment 3512 connected to one end of the first segment 3511 close to the first guide wheel 352, one end of the second segment 3512 is wound around and abutted against a winding surface of the first guide wheel 352 close to the second guide wheel 353, and the other end of the second segment 3512 is wound around and abutted against a winding surface of the second guide wheel 353 close to the first guide wheel 352.

The outer peripheral surface of the second guide wheel 353 forms a winding surface. In order to prevent the rope 351 from falling off the second guide wheel 353, an annular groove may be further provided on an outer circumferential surface of the second guide wheel 353 to limit the axial movement of the rope 351 along the second guide wheel 353.
