Dishwashers have an approximately rectangular parallelepiped structure, which generally comprises basic components such as a housing, a liner, a door body, a bowl and basket assembly, a water inlet valve, a spray arm, a pump, a control device, etc.
The shell is used for limiting an external structure, the inner container is used for forming a washing chamber, and the shell and the inner container are both of box body structures with openings. For example, the openings in the housing and the tub of the built-in dishwasher are typically provided at the front thereof, and the openings in the housing and the tub of the sink dishwasher are typically provided at the top thereof.
The door body is arranged at the opening and used for opening or closing the washing space, and when the door body opens the opening, a user can place articles to be washed in the washing chamber or take out the washed articles from the washing chamber.
For the two different types of dish washing machines, the installation positions of the door bodies are different, for example, the door body of the embedded dish washing machine is installed at the front part of the embedded dish washing machine, and the door body of the water tank type dish washing machine is installed at the top part of the water tank type dish washing machine.
The bowl basket assembly is arranged in the inner container and used for placing articles to be cleaned, wherein the articles to be cleaned can be tableware, fruits and vegetables, egg articles and the like.
The water inlet valve is installed on a pipeline between the water supply system and the water inlet pipe of the dish washing machine and used for injecting water into the washing chamber.
The spray arm is installed in the bottom of the inner container of the dish washer and is located below the dish basket assembly, water in the washing chamber is usually stored in a water tank formed by the inner container and is usually located at the bottom of the washing chamber, when the dish washer is started, the control device controls the water inlet valve to be opened, water in the water supply system flows into the water tank under the driving of water pressure, then the control device controls the pump to be opened, so that the water in the water tank is pushed to the spray arm, water outlets in different directions are formed in the spray arm, and the water is sprayed to the surface of tableware placed in the dish basket assembly through the water outlets of the spray arm, so that stains on the surface of the tableware are cleaned.
As is well known, ozone has a strong oxidizing effect and is widely used in the field of disinfection and sterilization. However, high concentrations of ozone have a strong pungent odor that can severely damage the central nervous system, reduce visual acuity and vision, damage the thyroid, and reduce lung function.
Thus, both the industrial sector and the sanitary sector have made clear demands on the ozone safety and hygiene standards: in daily production and life, the ozone concentration in the environment medium is not more than 0.2mg/m3。
However, some current dish washers sterilize dishes, fruits and vegetables by using a plasma generator, and the plasma generator generates high-concentration ozone during discharging due to the existence of a large amount of oxygen or dissolved oxygen in the use scene of the dish washer. Ozone dissolved in water can oxidize hypochlorous acid in water, thereby generating substances harmful to human health, and causing the water to generate thick disinfection water flavor which is attached to the surfaces of bowls, dishes, fruits, vegetables, hands and the like, thereby influencing the sensory experience of users.
For this reason, the dishwasher provided by the embodiment of the application aims to realize that the ozone generation amount is greatly reduced while the high-efficiency disinfection and sterilization efficiency of the plasma generation device is maintained.
FIG. 1 is a schematic structural diagram of a dishwasher in an embodiment of the present application; FIG. 2 is a bar graph of the main active materials and their concentrations generated by the surface discharge plasma generator in the water environment according to the embodiment of the present application; referring to fig. 1 and 2, the dishwasher in the embodiment of the present application has a shape of an approximate rectangular parallelepiped, the dishwasher includes a housing 1 and an inner container 2, a creeping discharge plasma generating device 3 is disposed on a bottom plate of the inner container 2, the creeping discharge plasma generating device 3 includes a power driving module and a ground electrode 31, a first surface of the ground electrode 31 is exposed in a washing chamber, when water is injected into the washing chamber, the first surface of the ground electrode 31 is immersed in the water, the water in the washing chamber is activated to obtain plasma activated water, and the plasma activated water contains H with a high concentration2O2(Hydrogen peroxide), NO2 -(nitrite ion), NO3 -(nitrate ion), and active substance such as OH (hydroxyl radical) with a certain concentration and UV light, the active substance rapidly spreads in the washing chamber along with the flow of water to kill various microbes such as bacteria, fungi, viruses, etc., so that when the plasma activated water is used for cleaning tableware, fruits and vegetables, a good sterilizing effect can be achieved.
In addition, since the concentration of active material OH generated during the discharge of the creeping discharge plasma generating apparatus 3 is relatively low, ozone O is generated3The concentration of (C) is lower, and in order to distinguish the concentration of the active substance OH and the concentration of the ozone O, the active substance OH and the ozone O are shown in FIG. 23The concentration is increased by 100 times, and is respectively increased by OH (× 100) and O3And (× 100) is shown.
FIG. 3 shows the ozone concentration n of the surface discharge plasma generator 3 with different power densities E in the embodiment of the present applicationO3One of the graphs of the variation with discharge time; FIG. 4 shows the present applicationIn the embodiment, the ozone concentration n of the surface discharge plasma generating device 3 is different under different power densities EO3And a second graph showing the variation with discharge time. As can be seen from FIGS. 3 and 4, when the creeping discharge plasma generating apparatus 3 discharges at different power densities E, the concentration n of ozone increases with the increase of the discharge time tO3The trend of the change is different.
Specifically, when the power density E is less than or equal to 0.1W/cm2In time, the concentration n of ozoneO3The discharge time t is increased continuously, and when the discharge time t is within 60s, the concentration n of ozoneO3Is increased rapidly, and when the discharge time t exceeds 60s, the concentration n of ozone is increasedO3Tends to be constant; when the power density E is 0.2W/cm2～3W/cm2In time, the concentration n of ozoneO3Can be rapidly reduced within 60s and is close to 0 ppm.
Whereby the power density E of the creeping discharge plasma generator 3 in the embodiment of the present application is 0.2W/cm2～3W/cm2The surface discharge plasma generating device 3 can hardly generate ozone while keeping high-efficiency sterilization and disinfection capacity, avoids the problems that ozone damages the central nervous system of a human body, reduces visual sensitivity and eyesight, damages the thyroid gland and reduces the lung function, and meanwhile, does not generate peculiar smell on the surfaces of tableware and fruits and vegetables in a water body, so that the sensory experience of a user can be improved.
Fig. 5 is a graph showing the variation of the half-life period of ozone with temperature, and it can be known from fig. 5 that the half-life period of ozone is rapidly reduced with the increase of temperature, because the electron temperature of the plasma generated by the creeping discharge plasma generating device 3 is different under different output voltages of the power driving module, the electron temperature of the plasma is higher when the output voltage is higher, and when the output voltage of the creeping discharge plasma generating device 3 is 5kV to 10kV at the power driving module, the working temperature of the creeping discharge plasma generating device 3 is about 60 ℃ to 80 ℃, and the higher temperature is favorable for the decomposition of ozone.
In order to further accelerate the decomposition of ozone, the creeping discharge plasma generating apparatus 3 in the embodiment of the present application further includes: and a catalyst coated on a surface of the insulating layer 32 on a side close to the ground electrode 31 or on the ground electrode 31, the catalyst serving to decompose ozone.
For example, the catalyst is TiO2Semiconductor catalyst, or MnO2A semiconductor catalyst.
In addition, by controlling the output voltage of the power driving module to be 5kV to 10kV, it can also be ensured that the discharge type of the plasma generating device is creeping discharge, and the creeping discharge can cause the first surface of the ground electrode 31 to generate large-area discharge plasma, thereby ensuring that the sterilization of the creeping discharge plasma generating device 3 is more efficient.
It should be noted that: the power density E is P/S, where P is the output power of the driving power module, S is the exposed area of the first surface of the ground electrode 31 in the washing chamber, and the output power P of the driving power module is equal to the product of the output current I and the output voltage U of the power driving module, i.e., P is U.
Because the exposed area S of the first surface of the ground electrode 31 in the washing chamber is designed when the dishwasher is designed, that is, the exposed area S of the first surface of the ground electrode 31 in the washing chamber is known, then according to E ═ P/S, the power range of the output power P of the driving power module is known, and the value range of the output voltage of the power driving module is 5kV to 10kV, so that the value range of the output current is known, the control chip only needs to control the value range of the output voltage to be 5kV to 10kV, and make a corresponding adjustment on the output current, so as to finally ensure that the output power P of the power driving module is relatively stable.
