DETAILED DESCRIPTION

[0022] Example:

[0023] In this embodiment, if Figures 1 to 6A water treatment device for a dishwasher is shown, which includes a first filter element 2, a second filter element 3, a sterilizing device 4 and a static mixer 5; a first water inlet pipe 11 is arranged on the first filter element 2; the inlet end of the second filter element 3 is connected to the first filter element 2, and the outlet end is connected to the sterilizing device 4; an ozone generator 44 is arranged in the sterilizing device 4, and the two ends of the ozone generator 44 are respectively connected to the second filter element 3 and the static mixer 5; a second water outlet pipe 12 is arranged on the static mixer 5.

[0024] Specifically, Figure 5 As shown, the sterilization device 4 includes a second water inlet pipe 41, a first water outlet pipe 42, a magnetizing device 43 and an ozone generator 44; the magnetizing device 43 is arranged between the second water inlet pipe 41 and the ozone generator 44, and the first water outlet pipe 41 is arranged between the ozone generator 44 and the static mixer 5.

[0025] The magnetizing device 2 is used to generate a magnetic field to magnetize the liquid flowing through, change the physical properties of the water, and effectively turn the macromolecules in the water into small molecules, thereby providing an efficient water environment for cleaning stains and sterilizing. The magnetizing device 2 used in the utility model is a commercially available product, and its internal structure and working principle are not described in detail here.

[0026] The ozone generator 44 is used to generate ozone. After the ozone and water flow are fully mixed in the static mixer 5, the ozone is released in the water to generate a large amount of active oxygen, negative ions, free oxygen molecules, and super oxide ions, which effectively remove and decompose stains, sterilize and disinfect, and keep the treated water antibacterial. As a result, the water flow reaching the dishwasher is rich in negative oxygen ions and evenly distributed, so that the overall water quality is fully improved, and the use of detergents can be stopped or reduced.

[0027] In this embodiment, the ozone generator 4 is a commercially available product, which will not be described in detail here and the structure of the utility model patent with the authorization publication number CN1122110582A may be referred to.

[0028] In this embodiment, if Figure 5 As shown, the sterilization device 4 further includes a water flow sensor 45 , which is disposed between the ozone generator 44 and the first water outlet pipe 42 .

[0029] In this embodiment, the water flow sensor 45 is a flow meter, which is used to display the size and flow rate of the water flow, so as to control the ozone output amount and output rate of the ozone generator 44 as needed.

[0030] In this embodiment, if Figure 6 As shown, the first water inlet pipe 11 and the second water outlet pipe 12 are arranged on the housing 1 , and a control module 13 is also arranged on the housing 1 . The control module 13 is electrically connected to the sterilization device 4 .

[0031] Specifically, the control module 13 is electrically connected to the water flow sensor 45, the ozone generator 44 and the magnetization device 43. The control module 13 is a touch-sensitive industrial computer. The water flow sensor 45 can feed back the water flow rate and water flow speed flowing through the ozone generator 44 and display them on the control module 13. The ozone generator 44 and the magnetization device 43 can be turned on, off and the power can be adjusted through the touch control module 13.

[0036] In this embodiment, six groups of rare earth ceramic core tubes are fired at high temperature, and water flows through multiple groups of rare earth ceramic core tubes fired at high temperature. The surface of each group of core tubes has dense pores, and the filtration produced by water flowing through the pores has a super filtering effect on impurities and oil stains. Micro-nano water with positive and negative electrons is sprayed onto the surface of the dishes, and a large amount of micro-nano water is used to entrain oil stains and free the dishes by the principle of mutual attraction, and pure physical degreasing does not leave any chemical components.
