[0021] Example 1 like Figures 1 to 8 As shown, this embodiment discloses a water cup and a dishwasher with a plasma sterilization function, the dishwasher comprises a water cup, a base 70, an inner tank 80 and a water guide plate 90, wherein: The water cup includes a water cup body 10, a plasma sterilization module 20, a fan 30 and a sealing module 40; The water cup body 10 is provided with a water cup cavity 11 with an open upper end; The plasma sterilization module 20 includes a shell 21 fixed to the outside of the water cup body 10 and having an air duct 201 inside, and a plasma generator 22 arranged in the shell 21. The water cup body 10 is provided with a through hole 12 for connecting the air duct 201 and the water cup cavity 11. The air duct 201 is provided with an electrode needle 23 electrically connected to the plasma generator 22. When the electrode needle 23 is energized, positive and negative ions are generated in the air duct 201. The fan 30 is disposed on the housing 21, and is used to blow the positive and negative ions in the air duct 201 through the through hole 12 and into the water cup cavity 11; The sealing module 40 includes a sealing plug 41 and a driving device 42 for driving the sealing plug 41 to insert into or withdraw from the through hole 12; The housing 21 is also fixedly connected to the base 70; The inner tank 80 is fixed to the upper end of the base 70, and the inner side of the inner tank 80 has a washing area 81 connected to the water cup cavity 11; The water guide plate 90 is fixed at the junction of the base 70 and the inner container 80 , and the water cup body 10 is fixed at the lower end of the middle part of the water guide plate 90 .

[0022] In the dishwasher of this embodiment, the operator can place pots, bowls or other items to be washed in a rack (not shown), and then push the rack into the washing area 81 inside the inner tank 80, and guide the water in the water cup cavity 11 to the water diversion cavity 13 through the washing pump 50, and the water diversion cavity 13 is connected to a main spray arm (not shown), and the regional washing outlet 15 at one end of the water diversion cavity 13 is connected to an auxiliary spray arm (not shown), and the main spray arm and the auxiliary spray arm both extend into the washing area 81, and water is sprayed toward the washing area 81 through the main spray arm and the auxiliary spray arm, so as to rinse away dirt on the pots, bowls or other items to be washed.

[0023] The present embodiment further adds a plasma sterilization module 20, a fan 30 and a sealing module 40. During washing, since the water cup cavity 11 is filled with water, in order to prevent water from entering the air duct 201 of the plasma sterilization module 20 and causing leakage of internal electronic equipment, the driving device 42 can be used to drive the sealing plug 41 to be inserted into the through hole 12 to block the through hole 12, thereby preventing water from entering the air duct 201 from the through hole 12; after washing, the driving device 42 drives the sealing plug 41 to withdraw from the through hole 12, so that the air duct 201 is connected to the water cup cavity 11. The plasma generator 22 and the fan 30 can be controlled to work. After the plasma generator 22 is started, the electrode needle 23 generates positive and negative ions after being energized. The electrode needle 23 is arranged in the air duct 201, so there are a large number of positive and negative ions in the air duct 201. The positive and negative ions in the air duct 201 are then blown into the water cup cavity 11 through the through hole 12 by the fan 30. The positive and negative ions are used to disinfect and sterilize the space in the water cup cavity 11 and the washing pump 50, so as to prevent bacteria from breeding in the space in the water cup cavity 11 and the washing pump 50, causing the tableware or the dishwasher cavity to mold.

[0024] In addition, the wind blown by the fan 30 can also blow and dry the water cup cavity 11, so that the inside of the water cup cavity 11 maintains a dry environment.

[0025] Please refer to Figure 2 The shell 21 is also snap-connected to the base 70 to facilitate disassembly and maintenance.

[0026] Please refer to Figure 3 and Figure 4 The water guide plate 90 is a concave structure. Through such a structure, the water dripping from the washing area 81 during the washing process can be quickly guided into the water cup cavity 11, and the structure is ingenious.

[0027] Please refer to Figure 5 and Figure 6 The water cup body 10 is provided with a water diversion cavity 13, the water diversion cavity 13 is connected with a washing pump interface 14 and a regional washing outlet 15, the washing pump interface 14 is connected with a washing pump 50, and the washing pump 50 is used to guide the water in the water cup cavity 11 to the water diversion cavity 13; the upper end of the water diversion cavity 13 is used to connect the main spray arm, and the regional washing outlet 15 is used to connect the auxiliary spray arm; the water in the water diversion cavity 13 is sprayed toward the washing area 81 through the main spray arm and the auxiliary spray arm, so as to rinse the dirt on the pots, bowls or other items to be washed.

[0028] Furthermore, a drainage interface 16 is provided at the bottom of the water cup body 10, and the drainage interface 16 is connected to a drainage pump 60. When the sewage needs to be discharged after washing, the sewage is collected in the water cup cavity 11, and then passes through the drainage pump 60 to discharge the water out of the machine.

[0029] Please refer to Figure 5 and Figure 8 The drive device 42 of this embodiment adopts a wax motor. The wax motor is a linear electric actuator with a small product size, suitable for installation in a dishwasher, and has a large working stroke output thrust or pulling force. Since the sealing plug 41 is used in this embodiment to seal with the through hole 12, a large pulling force is required when the drive device 42 drives the sealing plug 41 to withdraw from the through hole 12, and the wax motor can just meet the above requirements. Of course, the use of the wax motor in this embodiment is only one of the preferred implementations. In other embodiments, linear drive devices such as electric cylinders, air cylinders, and hydraulic cylinders can also be used, and are not limited to wax motors.

[0030] As the optimal implementation mode, the sealing plug 41 of this embodiment includes a truncated cone-shaped rubber head and a telescopic sealing cover connected to one end of the rubber head. The output shaft of the driving device 42 is fixedly connected to the rubber head. The telescopic sealing cover is clamped between the mounting seat 25 and the air duct joint 24 through the sealing ring 26. The truncated cone-shaped rubber head can better guide the rubber head to be inserted into the circular through hole 12, and quickly make the axis center line of the rubber head and the axis center line of the through hole 12 colinear, so that the rubber head and the through hole 12 have a better fit and the sealing is improved.

[0031] Please refer to Figure 8 A duct joint 24 is connected to the shell 21, a mounting seat 25 is fixed on the duct joint 24, a driving device 42 is fixed on the mounting seat 25, a sealing ring 26 is provided at the connection between the mounting seat 25 and the duct joint 24, the sealing ring 26 is sleeved on the outside of the sealing plug 41, and the sealing ring 26 is made of elastic material, which improves the sealing performance of the connection between the mounting seat 25 and the duct joint 24.

[0032] Please refer to Figure 8The shell 21 is snap-connected with the air duct connector 24, which is convenient for disassembly, inspection, cleaning, maintenance or replacement.

[0033] Please refer to Figure 7 and Fig. 9 The driving device 42 is provided with a card plate 27, and the mounting seat 25 is provided with a card slot 251 that matches the card plate 27. The mounting seat 25 is fixed to the air duct joint 24 by a screw 28; the screw 28 is provided on one side of the card slot 251 to limit the card plate 27; when the driving device 42 is installed, the card plate 27 is first rotated clockwise into the card slot 251, and then the screw 28 is locked, and the card plate 27 is limited by the screw 28 to prevent the card plate 27 from falling out of the card slot 251; in addition, the screw 28 is also used to fix the mounting seat 25 and the air duct joint 24, realizing two functions and having an ingenious structure.

[0034] Please refer to Figure 7 and Fig. 9 The shell 21 includes an upper shell 211 and a lower shell 212, which are snap-connected. Moreover, a concave-convex skirt 213 is provided at the junction of the upper shell 211 and the lower shell 212 to prevent gas leakage in the air duct 201 and improve sealing.

[0035] Furthermore, the lower shell 212 is provided with a positioning column 214 for positioning the fan 30 and the plasma generator 22; the upper shell 211 is provided with a convex rib 215 for limiting the fan 30 and the plasma generator 22. The lower shell 212 and the positioning column 214 can be made by injection molding, and the upper shell 211 and the convex rib 215 can be made by injection molding. With such a design, when the upper shell 211 and the lower shell 212 are combined, the positioning and limiting effects of the positioning column 214 and the convex rib 215 can achieve fixation of the fan 30 and the plasma generator 22, eliminating the need for screws, reducing assembly procedures, and improving production efficiency.

[0036] Example 2 like Figures 9-10 As shown, the difference between this embodiment and embodiment 1 lies in that the position of the plasma generator 22 is adjusted to the outside of the shell 21, and the length of the air duct 201 on one side of the fan 30 is extended to avoid the fan 30 generating noise due to the fan 30 being too close to the turning point of the air duct 201. The plasma generator 22 is arranged in parallel with the air duct 201, which can shorten the length of the entire plasma sterilization module 20 and make the structure more compact. In addition, this embodiment also adjusts the electrode needle 23 to the inside of the turning point of the air duct 201, which can make the structure of the entire ion sterilization module more compact.

[0037] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
