[0019] The present invention provides a dishwasher with an electrolytic water disinfection function. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] like Figures 1 to 8 As shown, this embodiment discloses a dishwasher with electrolytic water disinfection function, comprising: A water cup 10, wherein the water cup 10 is provided with a water cup cavity 11 with an open upper end, and the water cup 10 is also provided with a water inlet 12 connected to the water cup cavity 11; The water supply module includes a water softener 21 disposed below the water cup 10, a first pipe 22 connected between the drain port of the water softener 21 and the water inlet 12, and a three-way valve 23 disposed on the first pipe 22; The electrolysis module includes a water electrolysis device 30 connected to the three-way valve 23 via a second pipeline 36; The atomization module includes an atomization device 40 connected to the water electrolysis device 30 through a third pipe 47, a fourth pipe 44 connected to the discharge port of the atomization device 40, and a steam outlet structure arranged on the fourth pipe 44, the steam outlet structure includes a first steam outlet nozzle 45 extending into the water cup cavity 11.

[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 61 inside the inner tank 60, and guide the water in the water cup cavity 11 to the water diversion cavity 13 through a washing pump (not shown), 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 61, and water is sprayed toward the washing area 61 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] This embodiment adds a water supply module, and the water inlet of the water softener 21 can be connected to the tap of tap water. After the tap is turned on, the tap water enters the water softener 21 through the water softener 21. The water softener 21 can adopt an ion exchange water softener in the prior art with fully automatic control of operation and regeneration operation process, and use sodium type cation exchange resin to remove calcium and magnesium ions in the water to reduce the hardness of raw water, so as to achieve the purpose of softening hard water, thereby avoiding the scaling of carbonate in the pipeline and the water cup cavity 11. During washing, the drain outlet of the water softener 21 discharges the softened water into the first pipeline 22, and the softened water can be controlled by the on-off control of the three-way valve 23 to enter the water cup cavity 11 for normal washing.

[0024] The present embodiment further adds an electrolysis module and an atomization module. When the water cup cavity 11 and the washing area 61 need to be disinfected and sterilized, the softened water discharged from the water softener 21 can also enter the second pipe 36 through the on-off control of the three-way valve 23, and enter the electrolysis device 30 through the second pipe 36 for electrolysis. After a period of electrolysis, the electrolysis device 30 is filled with ozone-rich electrolyzed water, the atomization device 40 is started, and the electrolyzed water enters the atomization device 40 through the third pipe 47 to be atomized to form water vapor rich in ozone, and then is transported through the fourth pipe 44 to the atomization device 40. It is sent to the first steam outlet 45 and the second steam outlet 46, so that the ozone-rich water vapor is sprayed into the water cup cavity 11 and the washing area 61. The strong oxidizing property of ozone destroys the structure and function of bacteria, viruses and other microorganisms, thereby making them inactive; after ozone combines with bacteria, it will quickly decompose and produce new oxygen, thereby killing the bacteria; in addition, ozone can also enter the cell through penetration, damage the cell wall and cell membrane, denature the protein and enzyme in the cell, and cause cell death; it has a good disinfection and sterilization effect.

[0025] The present application utilizes ozone-rich water vapor to disinfect and sterilize the space within the water cup cavity 11 and the washing area 61, thereby preventing bacteria from growing in the space within the water cup cavity 11 and the washing area 61, causing tableware or the dishwasher cavity to become moldy.

[0026] Please refer to Figure 7 and Figure 8 The water electrolysis device 30 of this embodiment includes a lower shell 31, an upper shell 32 fixed to the upper end of the lower shell 31, and an electrode 33 arranged at the inner bottom of the lower shell 31. After the water electrolysis device 30 is turned on, when the current passes through the water, the ions on the positive and negative electrodes are introduced into the electrode 33, and receive or release electrons on the electrode 33 to be reduced or oxidized, thereby decomposing water into hydrogen and oxygen; at the same time, during the electrolysis process, some oxygen molecules are further oxidized into ozone molecules on the surface of the electrode 33, and the ozone is mixed in the water to form electrolyzed water, and then enters the atomization device 40 through the third pipe 47 to be atomized to form ozone-rich water vapor.

[0027] Furthermore, the lower shell 31 is a trumpet-shaped structure that is larger at the top and smaller at the bottom. A water trough 301 is formed on the inner side of the lower shell 31. The electrode 33 is located in the middle of the water trough 301 so that water can gather near the electrode 33. The lower shell 31 is also connected to a steam exhaust port 302 that is connected to the water trough 301. One end of the third pipe 47 is connected to the steam exhaust port 302. The steam exhaust port 302 is snap-connected to the third pipe 47, which has low assembly difficulty and high assembly efficiency.
