[0027] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides a water cup assembly and a dishwasher. A plurality of embodiments are given below to describe the water cup assembly and the dishwasher provided by the utility model in detail.

[0029] Example 1

[0030] The water cup assembly provided in this embodiment is as follows: Figure 1 to Figure 2 As shown, it includes a water cup 1 and a piston 2; a cavity 4 is provided at the bottom of the water cup 1, the top of the cavity 4 is connected to the water cup 1, the cavity 4 is provided with a drainage structure 43, and the drainage structure 43 connects the cavity 4 with the outside; the piston 2 is arranged in the cavity 4, the piston 2 can seal the cavity 4, and the piston 2 can rise and fall along the axial direction of the cavity 4.

[0031] Specifically, cavity 4 is arranged below water cup 1, the top of cavity 4 is connected with water cup 1 and forms an opening, and the bottom of cavity 4 is a closed structure. When residual water in water cup 1 needs to be discharged, piston 2 is driven to move upward. After piston 2 moves to the position where the piston 2 fails to seal cavity 4, the residual water in water cup 1 will fall into cavity 4 through the top of cavity 4, and be discharged to the outside through drainage structure 43. After most of the residual water is discharged to the outside through drainage structure 43, piston 2 is driven to move downward. After piston 2 moves to the position where it can seal cavity 4, piston 2 continues to move downward, and the remaining residual water in water cup 1 is drawn into cavity 4, so that the residual water does not remain in water cup 1 connected with the inner tank, and the residual water can be better separated from the inner tank, reducing the influence of residual water on the drying performance of the inner tank, thereby improving user experience.

[0032] The cavity 4 can be a cylindrical cavity 4 or any other suitable shape such as a stepped cavity. The cavity 4 is coaxially arranged with the piston 2 , and the piston 2 can be raised and lowered along the axial direction of the cavity 4 .

[0033] The water cup 1 and the cavity 4 can be fixedly connected or integrally formed. The drainage structure 43 can be a drainage port or a drainage channel.

[0034] Furthermore, the cavity 4 is a stepped cavity; the stepped cavity includes a first cavity 41 and a second cavity 42, the cross-sectional area of ​​the first cavity 41 is larger than the cross-sectional area of ​​the second cavity 42; the top end of the first cavity 41 is connected to the water cup 1, and the bottom end of the first cavity 41 is connected to the top end of the second cavity 42; the piston 2 includes a plug body 21, the plug body 21 is arranged in the first cavity 41, the plug body 21 can seal the first cavity 41, the plug body 21 can be raised and lowered along the axial direction of the first cavity 41, and the plug body 21 can abut against the bottom wall of the first cavity 41.

[0035] The first cavity 41 and the second cavity 42 may be fixedly connected or may be an integrally formed structure.

[0036] The first cavity 41 is arranged below the water cup 1, and the second cavity 42 is located below the first cavity 41, and the bottom end of the second cavity 42 is a closed structure. The top of the first cavity 41 is connected with the water cup 1 and forms an opening. When the residual water in the water cup 1 needs to be discharged, the plug body 21 is driven to move upward. After the plug body 21 moves to the position where the plug body 21 fails to seal the first cavity 41, the residual water in the water cup 1 will fall into the first cavity 41 through the opening at the top of the first cavity 41, thereby entering the cavity 4, and being discharged to the outside through the drainage structure 43. After most of the residual water is discharged to the outside through the drainage structure 43, the plug body 21 is driven to move downward. After the plug body 21 moves to the position where it can seal the first cavity 41, the plug body 21 continues to move downward, and the remaining residual water in the water cup 1 is drawn into the first cavity 41 until the plug body 21 abuts against the bottom wall of the first cavity 41, and the plug body 21 stops moving, and the residual water stays in the first cavity 41.

[0037] The plug body 21 can abut against the bottom wall of the first cavity 41 , so as to limit the descending position of the plug body 21 .

[0038] In this embodiment, the outer contour of the plug body 21 is cylindrical, and the outer contours of the first cavity 41 and the second cavity 42 are also cylindrical, and the radius of the first cavity 41 is larger than the radius of the second cavity 42. The first cavity 41, the second cavity 42 and the piston 2 are coaxially arranged.

[0039] The plug body 21 can seal the first cavity 41 . The side wall of the plug body 21 can be arranged in close contact with the side wall of the first cavity 41 to achieve sealing. Alternatively, a first sealing member can be arranged on the plug body 21 .

[0040] Furthermore, a first sealing member is provided on the side wall of the plug body 21 , and the first sealing member is located between the side wall of the plug body 21 and the side wall of the first cavity 41 .

[0041] The first sealing member may be a sealing protrusion, or a sealing ring or any other suitable form.

[0042] The first sealing member is disposed between the side wall of the plug body 21 and the side wall of the first cavity 41 , so that the plug body 21 seals the first cavity 41 .

[0043] In the process of driving the plug body 21 to move upward, when the plug body 21 moves to the point where the first sealing member extends from the opening to above the first cavity 41 , the sealing effect of the plug body 21 on the first cavity 41 becomes invalid.

[0044] In the process of driving the plug body 21 to move downward, when the plug body 21 moves to the point where the first sealing member extends into the first cavity 41 through the opening, the plug body 21 can seal the first cavity 41 .

[0045] Along the axial direction of the plug body 21 , the first sealing member may be disposed at the top of the plug body 21 , may be disposed at the middle of the plug body 21 , or may be disposed at the top and the middle of the plug body 21 respectively.

[0046] In this embodiment, the first sealing member is disposed on the top of the plug body 21 .

[0047] In this embodiment, the first sealing member is a sealing ring, which is sleeved on the side wall of the plug body 21 and is easy and convenient to install.

[0048] Furthermore, the piston 2 also includes a connecting mechanism, which is connected to the bottom end of the plug body 21; the connecting mechanism can be lifted and lowered along the axial direction of the cavity 4; the connecting mechanism includes a sealing structure, which can seal the second cavity 42.

[0049] One end of the connection mechanism is fixed to the bottom end of the plug body 21 , and the connection structure can be lifted and lowered in the cavity 4 along the axial direction of the cavity 4 .

[0050] The connection mechanism can be used to connect with the driving device 3, and the driving device 3 is used to drive the plug body 21 to rise and fall. When the plug body 21 abuts against the bottom wall of the first cavity 41, the connection mechanism is located in the second cavity 42, and when the plug body 21 rises and falls, the connection mechanism rises and falls with the plug body 21.

[0051] The drainage structure 43 can be arranged in the second cavity 42. When the residual water in the water cup 1 needs to be discharged, the plug body 21 and the connecting mechanism are driven to move upward. After the plug body 21 moves to the position where the plug body 21 fails to seal the first cavity 41, the residual water in the water cup 1 will fall into the first cavity 41 through the opening at the top of the first cavity 41, and then fall into the second cavity 42, and finally be discharged to the outside through the drainage structure 43. The sealing structure can seal the second cavity 42. After the residual water enters the second cavity 42, the residual water will flow into the second cavity 42 above the sealing structure. Under the action of the sealing structure, the residual water can be prevented from entering the second cavity 42 below the sealing structure. When the bottom end of the connecting mechanism is connected to the driving device 3, the residual water can be prevented from contacting the driving device 3.

[0052] The sealing structure can seal the second cavity 42 . The sealing structure may be a columnar structure, and the sidewall of the columnar structure is arranged in close contact with the sidewall of the second cavity 42 , thereby achieving sealing.

[0053] Preferably, the connecting mechanism also includes a connecting piece 22; the sealing structure includes a sleeve 23 and a second sealing piece 24; the top end of the sleeve 23 is a closed structure, the bottom end of the sleeve 23 is an open structure, the second sealing piece 24 is arranged on the side wall of the sleeve 23, and the second sealing piece 24 is located between the side wall of the sleeve 23 and the side wall of the second cavity 42; the bottom end of the plug body 21 is connected to the top end of the sleeve 23 through the connecting piece 22.

[0054] The connecting member 22 may be a connecting rod, a connecting bracket or any other suitable form. The second sealing member 24 may be a sealing protrusion, a sealing ring or any other suitable form. One end of the connecting member 22 is fixed to the bottom end of the plug body 21, and the other end of the connecting member 22 is fixed to the top end of the sleeve 23. The connecting member 22 and the sleeve 23 are coaxially arranged, and the connecting member 22 and the sleeve 23 can be raised and lowered in the cavity 4 along the axial direction of the cavity 4.

[0055] In this embodiment, the second sealing member 24 is a sealing ring, which is sleeved on the side wall of the sleeve 23 .

[0056] The second sealing member 24 is disposed between the side wall of the sleeve 23 and the side wall of the second cavity 42, thereby sealing the second cavity 42. After the residual water enters the second cavity 42, the residual water will flow into the second cavity 42 above the second sealing member 24, and the second sealing member 24 can prevent the residual water from entering the second cavity 42 below the second sealing member 24. The driving device 3 can extend into the sleeve 23 through the open structure at the bottom end of the sleeve 23, and the driving device 3 is fixedly connected to the sleeve 23. The sleeve 23 can better protect the driving device 3 and prevent the residual water from contacting the driving device 3.

[0057] One end of the drainage structure 43 is connected to the cavity 4, and the other end of the drainage structure 43 is connected to the outside. In this embodiment, the other end of the drainage structure 43 is connected to the water storage structure, and the water in the cavity 4 can flow into the water storage structure through the drainage structure 43.

[0058] Furthermore, the drainage structure 43 is tubular, and the residual water flows into the water storage structure through the tubular drainage structure 43. The tubular structure occupies less space and is easy to arrange in the dishwasher.

[0059] The drainage structure 43 may be disposed on the bottom wall of the second cavity 42 , or on the side wall of the second cavity 42 .

[0060] In this embodiment, the drainage structure 43 is disposed on the side wall of the second cavity 42 .

[0061] When the residual water in the water cup 1 needs to be discharged, the plug body 21, the connecting piece 22 and the sleeve 23 are driven to move upward. After the plug body 21 moves to the position where the sealing of the plug body 21 to the first cavity 41 fails, the residual water in the water cup 1 will fall into the first cavity 41 through the opening at the top of the first cavity 41, and then fall into the second cavity 42. At this time, the sleeve 23 is located below the drainage structure 43, and the sleeve 23 and the connecting piece 22 do not block the drainage structure 43, and the residual water can be discharged to the outside through the drainage structure 43.

[0062] Furthermore, the top of the cavity 4 is connected to the lowest position of the water cup 1 .

[0063] In this way, the residual water in the water cup 1 can be gathered to the lowest position of the water cup 1, making it easier for the residual water to flow to the cavity 4, thereby enhancing the effect of discharging the residual water.

[0064] The piston 2 can be raised and lowered manually. For example, a piston rod is provided at the bottom end of the piston 2, and the piston rod passes through the bottom end of the cavity 4. A third sealing member is provided between the piston rod and the cavity 4. The piston 2 can be raised and lowered manually by holding the piston rod.

[0065] Furthermore, the water cup assembly also includes a driving device 3, which is connected to the bottom end of the piston 2, and the driving device 3 can drive the piston 2 to rise and fall.

[0066] The piston 2 is driven to rise and fall by the driving device 3, and the operation is convenient. The driving device 3 includes a push rod, which can rise and fall. The push rod passes through the bottom end of the cavity 4 and is fixedly connected to the bottom end of the piston 2. When the push rod is raised and lowered, the piston 2 can be driven to rise and fall.

[0067] Specifically, after the push rod passes through the bottom wall of the second cavity 42, it extends into the sleeve 23 through the open structure at the bottom end of the sleeve 23, and one end of the push rod extending into the sleeve 23 is fixedly connected to the sleeve 23, so that the push rod drives the piston 2 to rise and fall.

[0068] The sleeve 23 is sleeved on the outside of the push rod, and can protect the driving device 3 . Under the sealing effect of the second sealing member 24 , residual water can be prevented from contacting the driving device 3 .

[0069] The driving device 3 can be a hydraulic cylinder, a pneumatic cylinder, a push rod ignition machine, etc.

[0070] In this embodiment, the driving device 3 is a push rod motor, which is easy to assemble and has high stability in use.

[0071] Example 2

[0072] The dishwasher provided in this embodiment includes the cup assembly provided in embodiment 1. When the residual water in the cup 1 needs to be discharged, the piston 2 is driven to move upward. After the piston 2 moves to the position where the piston 2 fails to seal the cavity 4, the residual water in the cup 1 will fall through the top of the cavity 4 to the inside of the cavity 4 and be discharged to the outside through the drainage structure 43. After most of the residual water is discharged to the outside through the drainage structure 43, the piston 2 is driven to move downward. After the piston 2 moves to the position where it can seal the cavity 4, the piston 2 is continued to move downward, and the remaining residual water in the cup 1 is drawn into the cavity 4, so that the residual water does not remain in the cup 1 connected to the inner tank, and the residual water can be better separated from the inner tank, reducing the influence of the residual water on the drying performance of the inner tank, and improving the user experience.

[0073] Furthermore, the bottom of the dishwasher also includes a water storage structure, and the cavity 4 is connected to the water storage structure through a drainage structure 43.

[0074] The water storage structure may be a water storage box, or a water storage tank, etc. The water in the cavity 4 may flow into the water storage structure through the drainage structure 43. The water storage structure may be arranged at the bottom of the dishwasher to facilitate water to flow into the water storage structure and facilitate the disassembly and assembly of the water storage structure.
