[0054] Example 1

[0055] This embodiment provides a dishwasher.

[0056] In one embodiment, if Figures 1 to 6 As shown, the dishwasher includes a water inlet pipeline assembly, a washing assembly, a disinfectant water generating device a, and a water circuit switching structure. Among them, the first end of the water inlet pipeline assembly is connected to the water source, and the water inlet pipeline assembly includes a water inlet control element 9; the washing assembly is connected to the second end of the water inlet pipeline assembly. The water inlet a11 of the disinfectant water generating device a is connected to the second end of the water inlet pipeline assembly, and the water outlet a12 of the disinfectant water generating device a is connected to the washing assembly. A switch element is provided between the disinfectant water generating device a and the washing assembly, and the switch element can control the disinfectant water generated by the disinfectant water generating device a to flow into the washing assembly; the water circuit switching structure is provided between the second end of the water inlet pipeline assembly and the washing assembly and the disinfectant water generating device a, and has a first state in which the water inlet pipeline assembly is connected to the washing assembly, and a second state in which the water inlet pipeline assembly is connected to the disinfectant water generating device a.

[0057] The water inlet control element 9 may specifically be a water inlet solenoid valve or a water pump.

[0058] In this embodiment, when the dishwasher does not need to prepare disinfectant water, and only the washing component is washed with water, the water circuit switching structure is switched to the first state, and tap water enters through the first end of the water inlet pipeline component, and enters the washing component after passing through the second end of the water inlet pipeline component for washing; when the dishwasher needs to prepare disinfectant water, the water circuit switching structure is switched to the second state, and tap water enters through the first end of the water inlet pipeline component, and enters the water storage structure a1 after passing through the second end of the water inlet pipeline component, and electrolyzes in the water storage structure a1 to generate disinfectant water; when disinfection work is required, the switch element is turned on, so that the disinfectant water generated in the water storage structure a1 flows into the washing component, is diluted with the water in the washing component, and the disinfectant is sprayed on the tableware through the washing component for disinfection. The disinfectant water flows through the washing component, and can disinfect the washing component and the pipeline of the washing component, so as to achieve all-round disinfection and good disinfection effect. Moreover, the disinfectant water discharged by the dishwasher will not only not pollute the environment, but also purify the sewage.

[0059] On the basis of the above embodiments, in a preferred embodiment, the disinfectant water generating device a includes a water storage structure a1, a discharge electrode a2 and a loop electrode a3, a blocking medium and an air inlet channel. The water storage structure a1 has a water inlet a11 and a water outlet a12. The discharge electrode a2 is arranged in the water storage structure a1. The discharge electrode a2 is connected to the live wire b1 of the power supply device b. The power supply device can provide high voltage electricity to the discharge electrode a2. The loop electrode a3 is connected to the neutral wire b2 of the power supply device b. The air inlet channel is arranged on the water storage structure a1. The air inlet channel is suitable for passing air, and the air inlet channel surrounds the outside of the discharge electrode a2. When the dishwasher needs to prepare disinfectant water, the water circuit switching structure switches to the second state, and tap water enters through the first end of the water inlet pipe assembly, and then enters the water storage structure a1 through the second end of the water inlet pipe assembly. The power supply device b provides a high-frequency alternating voltage of 6KV-15KV to the discharge electrode a2, and the air enters the water storage structure a1 through the air inlet channel. The discharge electrode a2 of the disinfectant water generating device a undergoes a glow discharge phenomenon, and high-voltage discharge is used to generate plasma in a liquid environment. During discharge, high-energy electrons around the gas / liquid interface react violently with air and water molecules to generate highly oxidizing single oxygen atoms, ozone ion groups, hydrogen peroxide ion groups, hydroxyl groups, nitrite groups, etc., which have extremely strong killing ability against bacteria and viruses, and generate plasma disinfectant water with the ability to disinfect bacteria and viruses. The disinfection effect of the disinfectant water is better than traditional disinfection methods such as high-temperature disinfection, steam disinfection, ultraviolet disinfection, and silver ion disinfection.

[0060] The power supply device b may be a high-frequency high-voltage device or other device capable of providing high-voltage electricity. For example, the power supply device b includes a 220V power supply and a transformer connected to the power supply. The discharge electrode a2 is connected to the live wire of the transformer, and the return electrode a3 is connected to the neutral wire of the transformer. The return electrode a3 may be arranged on the outside or inside of the box of the water storage structure. When the return electrode a3 is arranged on the outside of the box, the box itself is made of an insulating material to form a blocking medium. When the return electrode a3 is arranged on the inside of the box, a blocking medium composed of an insulating material is arranged between the return electrode a3 and the discharge electrode a2. The blocking medium may specifically be an insulating sleeve wrapped around the return electrode a3 or the discharge electrode a2.

[0062] In one embodiment, the washing assembly includes a water cup 3, a washing pump 14, a spray arm 15, and an inner tank 1. During washing, water enters the water cup 3, the washing pump 14 pumps the water in the water cup 3 into the spray arm 15, and the spray arm 15 sprays the water into the inner tank 1 to spray and clean the tableware in the inner tank 1. The water in the inner tank 1 will flow into the water cup 3 for cyclic washing. After washing, the water in the inner tank 1 will be discharged into the sewer 17. In an alternative embodiment, the washing assembly includes the inner tank 1 and an ultrasonic generator disposed in the inner tank 1. During washing, water enters the inner tank 1, and the ultrasonic generator cleans the tableware in the inner tank 1. Therefore, the water outlet a12 of the disinfectant water generating device a can be connected to the water cup 3 or the inner tank 1, and the disinfectant water can flow into the water cup 3 or the inner tank 1.

[0063] On the basis of the above-mentioned embodiments, in a preferred embodiment, a flow meter 7 is provided between the disinfectant water generating device a and the second end of the water inlet pipeline assembly. In this embodiment, the setting of the flow meter 7 can control the amount of water entering the water storage structure a1, thereby controlling the amount of disinfectant water generated, and further controlling the proportion of the disinfectant water and the water in the washing assembly to be diluted. At the same time, the setting of the flow meter 7 can prevent the amount of water entering the water storage structure a1 from being too little or too much, thereby ensuring the preparation efficiency of the disinfectant water.

In this embodiment, when washing is required, the water inlet end of the three-way valve 13 is connected to the second water outlet end, and when disinfectant water needs to be prepared, the water inlet end of the three-way valve 13 is connected to the first water outlet end.

In this embodiment, no matter where the disinfectant water generating device a is installed, the disinfectant water generated by the disinfectant water generating device a can be pumped into the washing component. In an alternative embodiment, the switch element is a solenoid valve, in which the installation position of the disinfectant water generating device a needs to be higher than the bottom of the inner tank 1 of the dishwasher.

[0066] On the basis of the above-mentioned embodiments, in a preferred embodiment, the water inlet pipeline assembly includes: a sixth pipeline g6, a respirator 8, and a water softener 6, one end of the sixth pipeline g6 is connected to the water source, the other end of the sixth pipeline g6 is connected to the first end of the water inlet control element 9, the water inlet end of the respirator 8 is connected to the second end of the water inlet control element 9 through the seventh pipeline g7, the water outlet end of the respirator 8 is connected to the water inlet end of the water softener 6, and the water outlet end of the water softener 6 constitutes the second end of the water inlet pipeline assembly.

This embodiment can discharge the water vapor in the inner tank 1 by setting a respirator 8, and can buffer water when taking in water. The setting of the water softener 6 can soften the water before it enters the disinfection water generating device a and the washing component, and soft water is used for glow discharge to avoid scaling of the discharge electrode a2 and the loop electrode a3 in the disinfection water generating device a.

[0067] Specifically in one embodiment, the water outlet of the respirator 8 is sealedly connected to the water inlet of the water softener 6, and the water outlet of the water softener 6 is connected to the water inlet of the three-way valve 13 through the eighth pipeline g8.

During assembly, after the discharge electrode a2 and the return electrode a3 are installed on the upper cover a14, the upper cover a14 and the lower cover a13 are assembled together by sol welding, which is convenient for improving assembly efficiency.

[0081] On the basis of the above-mentioned embodiment, in a preferred embodiment, the upper cover a14 has an upper cover groove a141 which is recessed toward the lower cover a13, and the electrode fixing frame a7 is arranged in the upper cover groove a141. In this embodiment, by arranging the electrode fixing frame a7 in the installation groove, it is possible to avoid collision and interference between the electrode fixing frame a7 and other structures, and at the same time, the overall height of the disinfectant water generating device a can be reduced, thereby reducing the installation space occupied by the disinfectant water generating device a.

[0082] Among them, Fig.12 As shown, the discharge electrode a2 in the above embodiments includes a discharge electrode body a22 and an insulating sleeve a23 arranged outside the discharge electrode body a22, the second bending edge a21 is arranged on the insulating sleeve a23, and the lower end of the discharge electrode body a22 is arranged in a needle shape to facilitate the generation of an arc.

[0083] The dishwasher provided in this embodiment does not need to prepare disinfectant water, and only water is introduced into the washing chamber for washing. At this time, the three-way valve 13 is switched to the first state, and the tap water flows through the faucet 16, the sixth pipeline g6, the water inlet control element 9, the seventh pipeline g7, the respirator 8, the water softener 6, the eighth pipeline g8, the three-way valve 13, and the third pipeline g3 into the water cup 3 in sequence. The washing pump 14 pumps the water in the water cup 3 into the spray arm 15, and the spray arm 15 sprays the water into the inner tank 1 to spray and clean the tableware in the inner tank 1. The water in the inner tank 1 will flow into the water cup 3 for cyclic washing. After the washing is completed, the water is discharged into the sewer 17 through the drain pump 10, the first drain pipe g9, the U-shaped structure of the respirator 8, and the second drain pipe g10. When the dishwasher needs to prepare disinfectant water, the water circuit switching structure switches to the second state, and the tap water flows through the faucet 16, the sixth pipeline g6, the water inlet control element 9, the seventh pipeline g7, the respirator 8, the water softener 6, the eighth pipeline g8, the three-way valve 13, the first pipeline g1, the flow meter 7, and the second pipeline g2 in sequence to enter the water storage structure a1 of the disinfectant water generating device a, and electrolysis generates disinfectant water in the water storage structure a1. When disinfection is required, the pump 4 is turned on, so that the disinfectant water generated in the water storage structure a1 flows through the fourth pipeline g4, the pump 4, and the fifth pipeline g5 in sequence to enter the water cup 3, and is mixed and diluted with the water in the water cup 3. The washing pump 14 pumps the disinfectant water in the water cup 3 into the spray arm 15, and the spray arm 15 sprays the disinfectant water onto the inner tank 1 and the tableware in the inner tank 1 to disinfect the tableware. The disinfectant water flows through the water cup 3, the washing pump 14, the spray arm 15, and the inner tank 1, and can be disinfected in all directions, with a good disinfection effect. After the disinfection is completed, the washing pump 14 is started to discharge the disinfection water and the washing water, and then the hot air drying device is started to dry the tableware and the washing cavity. Finally, the dishwasher achieves the effect of washing, disinfecting and storing in one.
