Generally, the main core components of existing dishwashers include: an inner tank assembly, a water cup assembly, a spray arm assembly, a filter assembly, a washing pump, a drainage pump, pipelines, etc. Currently, dishwashers on the market generally perform main cleaning and tableware disinfection through high temperature (about 70°C).

[0003] In the prior art, some dishwashers use UVC ultraviolet lamps for disinfection, add silver ions to inhibit bacteria in the part materials, use steam high-temperature disinfection, hot air drying and other disinfection methods. The above disinfection methods mainly act on the surface disinfection of tableware, and have poor effects on the internal parts that cannot be seen.

[0004] There are also some dishwashers in the prior art that use ozone water for disinfection. Since the solubility of ozone in water is low, the sterilization effect is not very ideal, and most of the overflowing ozone is harmful to the human body. Summary of the Invention

[0011] Optionally, the disinfected water generating device includes an electrode fixing bracket fixed on the upper cover. The discharge electrode is fixed on the electrode fixing bracket. The upper end of the first insulating tube is hermetically connected to the electrode fixing bracket. The electrode fixing bracket is provided with a gas guiding channel communicating with the inside of the first insulating tube, and the gas guiding channel and the first insulating tube together constitute the air inlet channel.

[0012] Optionally, the electrode fixing bracket is provided with a fixing hole for fixing the discharge electrode. The gas guiding channel includes a gas guiding cavity surrounding the outside of the fixing hole and an air inlet provided on the electrode fixing bracket and communicating with the gas guiding cavity.

[0013] Optionally, a first sealing member is provided between the upper surface of the upper cover and the electrode fixing bracket. The first sealing member includes an annular body portion.

[0018] The technical solution of the present invention has the following advantages:

[0019] For the dishwasher provided by the present invention, when preparing disinfected water, tap water enters the water storage structure, and the power supply device provides a high-frequency alternating voltage of 6 kV - 15 kV to the discharge electrode. Air enters the water storage structure through the air intake channel. Glow discharge occurs at the discharge electrode of the disinfected water generating device, and plasma is generated in the liquid phase environment by high-voltage discharge. During discharge, high-energy electrons react violently with air and water molecules around the gas / liquid interface to generate plasma such as single oxygen atoms, ozonide ion groups, hydrogen peroxide ion groups, hydroxyl groups, and nitroso groups with strong oxidizing ability, which have extremely strong killing ability against bacteria and viruses, and generate plasma disinfected water with the ability to kill bacteria and viruses. The disinfection effect of the disinfected water is better than traditional disinfection methods such as high-temperature disinfection, steam disinfection, ultraviolet disinfection, and silver ion disinfection. When disinfection work needs to be carried out, the disinfected water generated in the water storage structure is made to flow into the washing assembly, diluted with the water in the washing assembly, and the disinfected liquid is sprayed onto the tableware through the washing assembly for disinfection. The disinfected water flowing through the washing assembly can disinfect the washing assembly and the pipeline of the washing assembly, achieving comprehensive disinfection with good disinfection effect. Moreover, the disinfected water discharged by the dishwasher not only does not pollute the environment, but also purifies the sewage.

[0020] Moreover, the setting of the fluid discharge part can timely discharge the gas generated inside the water storage structure, ensure the air pressure balance inside the water storage structure, and at the same time, when the water level in the water storage structure reaches the fluid discharge part, it overflows through the fluid discharge part, which can ensure the pressure balance inside the water storage structure. By making the outlet of the fluid discharge part face the power supply device, the ozone generated inside the water storage structure can be timely decomposed by the high temperature of the power supply device, avoiding harm to the human body caused by ozone.

[0046] Embodiment 1

[0047] As Figures 1 to 16 shown, this embodiment provides a dishwasher.

[0048] In one embodiment, the dishwasher includes a washing assembly, a disinfected water generating device a, and a power supply device b. The power supply device is capable of providing a high-frequency alternating voltage of 6 kV - 15 kV. The disinfected water generating device a includes a water storage structure a1, a discharge electrode a2, a loop electrode a3, a blocking medium, and an air inlet passage. The water storage structure a1 has a water inlet a11 and a water outlet a12. The water inlet a11 is adapted to communicate with a water source, and the water outlet a12 is connected to the washing assembly. The outlet of the fluid discharge portion a5 faces the power supply device b, and the power supply device can provide high-voltage electricity to the discharge electrode a2. The discharge electrode a2 is disposed within the water storage structure a1 and is connected to the live wire of the power supply device b. The loop electrode a3 is connected to the neutral wire of the power supply device b. The blocking medium is disposed between the loop electrode a3 and the discharge electrode a2. The air inlet passage is provided on the water storage structure a1 and is adapted to introduce air. The air inlet passage surrounds the outside of the discharge electrode a2.

[0049] In this embodiment, when it is necessary to prepare disinfected water, tap water enters the water storage structure a1. The power supply device b provides a high-frequency alternating voltage of 6 kV - 15 kV to the discharge electrode a2. Air enters the water storage structure a1 through the air inlet passage. The discharge electrode a2 of the disinfected water generating device a generates a glow discharge phenomenon. Plasma is generated in the liquid phase environment by high-voltage discharge. During the discharge, high-energy electrons react violently with air and water molecules around the gas / liquid interface to generate plasma with strong oxidizing ability, such as single oxygen atoms, ozonide ion groups, hydrogen peroxide ion groups, hydroxyl groups, nitrosyl groups, etc., which have a strong killing ability against bacteria and viruses. Plasma disinfected water with the ability to kill bacteria and viruses is generated. The disinfection effect of the disinfected water is better than traditional disinfection methods such as high-temperature disinfection, steam disinfection, ultraviolet disinfection, and silver ion disinfection. When it is necessary to perform a disinfection operation, the disinfected water generated in the water storage structure a1 is made to flow into the washing assembly and diluted with the water in the washing assembly. The disinfectant liquid is sprayed onto the tableware through the washing assembly for disinfection. The disinfected water flowing through the washing assembly can disinfect the washing assembly and the pipeline of the washing assembly, achieving full-range disinfection with good disinfection effect. Moreover, the disinfected water discharged by the dishwasher not only does not pollute the environment but also purifies the sewage.

[0050] The setting of the fluid discharge portion a5 can timely discharge the gas generated inside the water storage structure a1 to ensure the air pressure balance inside the water storage structure a1. At the same time, when the water level in the water storage structure a1 reaches the fluid discharge portion a5, it overflows through the fluid discharge portion a5, which can ensure the pressure balance inside the water storage structure a1. By facing the outlet of the fluid discharge portion a5 towards the power supply device b, the ozone generated inside the water storage structure a1 can be timely decomposed by the high temperature of the power supply device b, avoiding harm to the human body caused by ozone.

[0051] Among them, the power supply device b can be a high-frequency high-voltage device or other devices capable of providing high-voltage electricity. The loop electrode a3 can be arranged on the outside or inside of the box body of the water storage structure. When the loop electrode a3 is arranged on the outside of the box body, the box body itself is made of an insulating material to form a blocking medium. When the loop electrode a3 is arranged on the inside of the box body, a blocking medium made of an insulating material is arranged between the loop electrode a3 and the discharge electrode a2. The blocking medium can specifically be an insulating sleeve covering the loop electrode a3 or the discharge electrode a2.

[0052] Specifically, in one embodiment, a switching element is arranged between the water storage structure a1 and the washing assembly, and the switching element can control the disinfected water generated by the water storage structure a1 to flow into the washing assembly.

During washing, water enters the water cup, the washing pump pumps the water in the water cup into the spray arm, and the spray arm sprays the water into the inner tank to spray and clean the tableware in the inner tank. The water in the inner tank will flow back into the water cup for cyclic washing. After washing is completed, the water in the inner tank is discharged into the sewer. In an alternative embodiment, the washing assembly includes an inner tank and an ultrasonic generator arranged in the inner tank. During washing, water enters the inner tank, and the ultrasonic generator cleans the tableware in the inner tank. Therefore, the water outlet a12 of the disinfected water generating device a can be connected to the water cup or the inner tank, and the disinfected water can flow into the water cup or the inner tank. The switching element can specifically be a water pump arranged on the pipeline connecting the water outlet a12 and the water cup, or a water outlet solenoid valve arranged on the water storage structure a1 or at the water outlet a12.

[0054] Based on the above embodiments, in a preferred embodiment, the fluid discharge part a5 is arranged on the top wall of the water storage structure a1 and close to the power supply device b, and the fluid discharge part a5 extends towards the power supply device b. In this embodiment, the fluid discharge part a5 is relatively close to the power supply device b, and there is no need to connect a pipeline to the outlet of the fluid discharge part a5, and the structure is relatively simple.

[0055] Based on the above embodiments, in a preferred embodiment, the distance between the end of the air inlet channel and the box body of the water storage structure a1 is less than the distance between the end of the discharge electrode a2 and the box body. It should be noted that the end of the air inlet channel is the end of the air inlet channel located inside the box body. Combining Figure 2 , the end of the air inlet channel is its lower end, and the end of the discharge electrode a2 also refers to its lower end. In this embodiment, it can be ensured that a gas-liquid interface is formed on the lower side of the end of the discharge electrode a2, so that when the discharge electrode a2 discharges, high-energy electrons react violently with air and water molecules around the gas / liquid interface to generate plasma.

[0056] On the basis of the above embodiments, in a preferred embodiment, the water storage structure a1 includes a lower cover a13 and an upper cover a14 hermetically connected to the lower cover a13.

The electrode fixing bracket a7 is provided with a gas guiding channel communicating with the inside of the first insulating tube a6. The gas guiding channel and the first insulating tube a6 together form the air inlet channel. In this embodiment, the electrode fixing bracket a7 is used to fix both the discharge electrode a2 and the first insulating tube a6, which can further improve the assembly efficiency, and the structure of the air inlet channel is relatively simple and does not require additional space. In other alternative embodiments, the electrode fixing bracket a7 is only used to fix the discharge electrode a2. The air inlet channel includes a first air inlet section arranged around the outer side of the lower half of the discharge electrode a2 and a second air inlet section connected to the upper end of the first air inlet section. The second air inlet section is fixedly arranged on the upper cover a14 or the side wall of the water tank a1, and the second air inlet section is inclined.

The electrode fixing bracket a7 is used to fix the discharge electrode a2 and can also fix the first insulating tube a6. The structure is simple and compact. Moreover, since the air guiding cavity a72 surrounds the fixing hole a71, it can ensure that the air is evenly located outside the discharge electrode a2.

[0061] Specifically, the electrode fixing bracket a7 is provided with screw holes, and the electrode fixing bracket a7 is connected to the upper cover a14 by screws.

[0062] On the basis of the above-described embodiments, in a preferred embodiment, a first seal a8 is provided between the upper surface of the upper cover a14 and the electrode fixing bracket a7.

After installation, the electrode fixing bracket a7 presses on the upper end of the first seal a8, realizing the sealed connection between the first insulating tube a6 and the electrode fixing bracket. The sealing performance is good, and the first seal a8 can play a buffering and protecting role for the first insulating tube a6, preventing the first insulating tube a6 from being damaged by collision. Among them, the shape of the first groove a82 is preferably annular, and correspondingly, the first bending edge a62 is also annular.

[0063] In one embodiment, as Figure 2 and Figure 14 shown, the loop electrode a3 is hermetically connected to the upper cover a14 through a second seal a109, and the second seal a109 is an O-ring.

[0064] On the basis of the above-described embodiments, in a preferred embodiment, a second groove a711 is provided in the fixing hole a71, and the discharge electrode a2 has a second flange a21 adapted to be embedded in the second groove a711.

Among them, the shape of the second groove a711 is preferably annular, and correspondingly, the second flange a21 is also annular.

[0065] In an embodiment, a third bent edge a31 is provided at the upper end of the loop electrode a3, and the third bent edge a31 is fixedly connected to the upper cover a14. In this embodiment, the provision of the third bent edge a31 facilitates the fixing of the loop electrode a3 to the upper cover a14. Specifically, the third bent edge a31 is connected to the upper cover a14 by screws or welding. Among them, the shape of the third bent edge a31 is preferably annular.

[0067] Based on the above embodiment, in a preferred embodiment, the upper cover a14 has an upper cover groove a141 that is recessed toward the lower cover a13, and the electrode fixing bracket a7 is disposed in the upper cover groove a141. In this embodiment, by disposing the electrode fixing bracket a7 in the upper cover groove a141, it is possible to avoid the electrode fixing bracket a7 from colliding and interfering with other structures, and at the same time, the overall height of the disinfection water generating device a can be reduced, reducing the installation space occupied by the disinfection water generating device a.

[0068] Among them, as Figure 7 and Figure 8 shown, the discharge electrode a2 in each of the above embodiments includes a discharge electrode body a22 and an insulating sleeve a23 provided outside the discharge electrode body a22.
