DETAILED DESCRIPTION

[0043] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0044] With regard to dishwashers using liquid plasma disinfection technology, the inventors have found through testing and analysis that the existing dishwashers are equipped with a plasma reactor, which can produce disinfectant and be used to disinfect dishes. However, after disinfection, the dishwasher is mostly cleaned by blowing ambient air into the inner tank through a fan, or by heating ambient air and blowing it into the inner tank. This cleaning method has the following problems:

[0045] 1. After the dishwasher has been cleaned for a certain period of time, the moisture in the inner tank will increase, which will easily breed bacteria and produce odors, affecting the user experience.

[0046] 2. The water used in washing in the inner tank of the dishwasher cannot be completely drained away, especially in the corners where water is easily hidden. Over time, it is easy for bacteria to breed and produce odors.

[0047] 3. The drain pipe of the dishwasher is connected to the sewer pipe. The odor from the sewer pipe or its own drain pipe can easily enter the inner tank, affecting the user experience.

[0048] Based on the above problems, the inventors have designed and proposed the cleaning methods and dishwashers of the following embodiments of the present application to solve the above technical problems.

[0049] As shown in FIG. 1 , in one embodiment, a cleaning method is provided to ensure at least the following steps:

[0050] S100 , the discharge assembly 220 discharges to ionize air and generate ozone.

[0051] As shown in FIG2 , optionally, S110, the air in the water tank 210 is driven to circulate between the water tank 210 and the circulation pipeline, and the discharge component 220 discharges to ionize the air in the water tank 210 and generate ozone, while also ionizing the water in the water tank 210 and generating disinfectant. In this way, plasma is generated in the liquid environment in the water tank 210 by high-voltage discharge. During discharge, high-energy electrons around the gas / liquid interface react violently with air and water molecules to generate OH - , H2O2 and other strong oxidizing substances to produce a solution with the ability to disinfect bacteria and viruses. In addition, during discharge, the air in the water tank 210 keeps circulating and ionized to continuously produce ozone, so that enough ozone can be produced in the water tank 210 to facilitate the subsequent cleaning of the cleaning device 100.

[0052] S200 , collecting the ozone generated by ionization into the storage element 310 .

[0053] As shown in FIG2 , optionally, S210, after the discharge component 220 has finished discharging, the first air valve 250 on the water tank 210 and the second air valve 330 on the storage component 310 are opened, and the ozone in the water tank 210 is pumped into the storage component 310 for storage. In this way, by opening the first air valve 250 and the second air valve 330, the air pressure in the water tank 210 and the storage component 310 can be kept balanced, the ozone in the water tank 210 can be pumped into the storage component 310, and the original air in the storage component 310 is discharged through the second air valve 330, so that the storage component 310 can collect as much ozone as possible and increase the concentration of ozone in the storage component 310.

[0054] It should be noted that the ozone volume V0 in the water tank 210 is set to be equal to the volume V1 of the water tank 210 - the water volume V2 in the water tank 210 , and the volume V3 of the storage element 310 is ≥ V0 .

[0055] S220, when the ozone in the water tank 210 is collected, the first gas valve 250 and the second gas valve 330 are closed, and the gas pumping to the storage member 310 is stopped. In this way, the ozone generated by the ionized air can be stored in the storage member 310 for subsequent cleaning of the cleaning device 100, and the disinfectant generated by the ionized water can be stored in the water tank 210 for subsequent disinfection and cleaning of the cleaning device 100.

[0056] S300 , when the cleaning device 100 needs to be cleaned, the ozone in the storage part 310 is released into the cleaning device 100 to inhibit bacteria and remove odors from the cleaning device 100 .

[0057] As shown in FIG. 2 , optionally, in S310 , when the cleaning device 100 needs to be cleaned, the odor concentration in the cleaning device 100 is detected and fed back to the controller.

[0058] S320, the controller controls the amount of ozone released from the storage unit 310 into the cleaning device 100 according to the fed-back odor concentration and the relationship between the odor concentration and the amount of ozone released which is preset in the controller, so as to inhibit bacteria and remove odor from the cleaning device 100. In this way, the controller can control the storage unit 310 to release different volumes of ozone according to the degree of odor in the cleaning device 100, ensuring that the released ozone can remove the odor in the cleaning device 100, thereby achieving cleaning of the cleaning device 100 while reducing the amount of ozone leakage and improving the safety of cleaning.

[0059] Among them, the relationship between the odor concentration and the amount of ozone released, which is pre-set in the controller, can be flexibly adjusted according to the actual needs of use.

[0060] Specifically in this embodiment, the relationship between the odor concentration and the amount of ozone released pre-set in the controller is:

[0061] When the odor concentration fed back to the controller is greater than or equal to 0 ppb and less than 10 ppb, the controller controls the storage element 310 to release 0 L of ozone into the cleaning device 100;

[0062] When the odor concentration fed back to the controller is greater than or equal to 10 ppb and less than 100 ppb, the controller controls the storage element 310 to release 1 L of ozone into the cleaning device 100;

[0063] When the odor concentration fed back to the controller is greater than or equal to 100 ppb and less than 1000 ppb, the controller controls the storage element 310 to release 2 L of ozone into the cleaning device 100;

[0064] When the odor concentration fed back to the controller is greater than or equal to 1000 ppb and less than 10000 ppb, the controller controls the storage element 310 to release 3 L of ozone into the cleaning device 100;

[0065] When the odor concentration fed back to the controller is greater than or equal to 10,000 ppb, the controller controls the storage element 310 to release 4 L of ozone into the cleaning device 100 .

[0066] As shown in FIG. 2 , in one embodiment, after step S200, the following steps are further included:

[0067] S400: When the cleaning device 100 needs to be disinfected, the disinfectant in the water tank 210 is pumped into the cleaning device 100, and the cleaning device 100 works to perform disinfection and cleaning.

[0068] Compared with the cleaning methods in the prior art, the cleaning method in the present application has at least the following advantages: while the discharge component 220 discharges to ionize water and produce disinfectant, it also ionizes the air and produces ozone, and then the ozone generated by the ionized air is collected by the storage component 310 and used to clean the cleaning device 100, thereby inhibiting the growth of bacteria in the cleaning device 100 and removing odors in the cleaning device 100, thereby increasing the cleaning effect of the cleaning device 100 and improving the user experience.

[0069] As shown in FIG3 , in one embodiment, a dishwasher 10 is provided, comprising a cleaning device 100, a plasma generator 200 and a storage device 300. The cleaning device 100 is provided with a cleaning chamber 111, and a first water inlet 131 and a first air inlet 121 communicated with the cleaning chamber 111. The plasma generator 200 comprises a water tank 210, a discharge assembly 220, a first air pump 230, a water pump 240 and a first air valve 250. The water tank 210 is provided with a receiving chamber 211 for receiving water and air, and a second water inlet 212, a first air outlet 213 and a first water outlet 214 communicated with the receiving chamber 211. The discharge assembly 220 and the first air valve 250 are both mounted on the water tank 210, the discharge assembly 220 is used to ionize the water and air in the receiving chamber 211, and the first air valve 250 is used to connect the receiving chamber 211 with the external environment. The air inlet end of the first air pump 230 is communicated with the first air outlet 213. The water inlet of the water pump 240 is communicated with the first water outlet 214, and the water outlet of the water pump 240 is communicated with the first water inlet 131. The storage device 300 includes a storage member 310, a second air pump 320 and a second air valve 330. The storage member 310 is provided with a storage cavity 311 and a second air inlet 312 and a second air outlet 313 communicated with the storage cavity 311. The second air inlet 312 is communicated with the air outlet of the first air pump 230, the air inlet of the second air pump 320 is communicated with the second air outlet 313, and the air outlet of the second air pump 320 is communicated with the first air inlet 121. The second air valve 330 is installed on the storage member 310 and is spaced apart from the second air inlet 312. The second air valve 330 is used to connect the storage cavity 311 with the external environment.

[0070] When the dishwasher 10 in the above embodiment is used, the first air valve 250 is opened, and water is injected into the accommodating chamber 211 through the second water inlet 212 until the water volume in the accommodating chamber 211 reaches a preset water volume (the preset water volume is less than the volume of the accommodating chamber 211), and then the first air valve 250 is closed. When it is necessary to produce disinfectant and ozone, the discharge component 220 discharges in the accommodating chamber 211 to ionize the water in the water tank 210 and generate disinfectant, and also ionizes the air in the water tank 210 and generates ozone. After the discharge component 220 finishes discharging, the first air valve 250 on the water tank 210 and the second air valve 330 on the storage unit 310 are opened, and the first air pump 230 pumps the ozone in the water tank 210 into the storage unit 310 for storage. When the ozone in the water tank 210 is collected, the first air valve 250 and the second air valve 330 are both closed, and the first air pump 230 stops pumping gas to the storage unit 310. When the cleaning device 100 needs to be disinfected, the water pump 240 pumps the disinfectant in the water tank 210 into the cleaning device 100, and the cleaning device 100 works to perform disinfection and cleaning. When the cleaning device 100 needs to be cleaned, the second air pump 320 pumps the ozone in the storage unit 310 into the cleaning device 100 to inhibit bacteria and remove odors from the cleaning device 100. The dishwasher 10 in the present application, while discharging through the discharge component 220 to ionize water and produce disinfectant, also ionizes air and produces ozone, and then collects the ozone generated by the ionized air through the storage unit 310, and uses it to clean the cleaning device 100, thereby inhibiting the growth of bacteria in the cleaning device 100, removing the odor in the cleaning device 100, and increasing the cleaning effect of the dishwasher 10, improving the user experience.

[0071] Specifically in this embodiment, the plasma generator 200 and the storage device 300 are both located outside the cleaning device 100. The cleaning device 100 can be any dishwashing device in the prior art. In other embodiments, the cleaning device 100 can also be configured as a laundry device, that is, the cleaning method in this application can also be applied to other cleaning machines such as washing machines.

[0072] The discharge assembly 220 may also be configured as any structure in the prior art capable of performing high voltage discharge in a liquid environment. The storage member 310 may be configured as a storage tank, a storage box or other storage structures.

[0073] As shown in FIG3 , the dishwasher 10 may further include a controller and an odor detector 410. The odor detector 410 is installed in the cleaning chamber 111 and is used to detect the concentration of odor in the cleaning chamber 111. The controller is in communication with the second air pump 320 and the odor detector 410. In this way, the odor detector 410 can detect the concentration of odor in the cleaning chamber 111 in real time and feed it back to the controller, so that the controller can control the storage device 300 to release different volumes of ozone according to the degree of odor in the cleaning device 100, ensuring that the released ozone can remove the odor in the cleaning device 100, ensuring that the cleaning device 100 remains clean, and reducing the leakage of ozone, thereby improving the safety of the dishwasher 10.

[0074] The controller may be a single chip microcomputer, a programmable logic controller or other control structure. The controller may be connected to the second air pump 320 and the odor detection element 410 via a data line, an electric wire, Bluetooth or other communication methods. In other embodiments, the controller may also be connected to the cleaning device 100, the plasma generator 200 and the storage device 300.

[0075] Specifically in this embodiment, the odor detection element 410 can be configured as an odor sensor.

[0076] As shown in FIG3 , optionally, the second air inlet 312 is located at the bottom of the storage member 310, and the second air valve 330 is located at the top of the storage member 310. In this way, during the process of the storage member 310 collecting ozone, the ozone fills the entire storage cavity 311 from bottom to top, and at the same time, the original air in the storage cavity 311 is discharged from the second air valve 330 at the top, so that the storage member 310 collects as much ozone as possible, and at the same time, the concentration of ozone in the storage cavity 311 is increased, thereby improving the cleaning effect of the dishwasher 10.

[0077] Specifically in this embodiment, the second air outlet 313 is also located at the bottom of the storage element 310 .

[0078] As shown in Fig. 3, optionally, the second air inlet 312 is located at the bottom of the storage element 310, and the second air valve 330 is located at the top of the storage element 310. In this way, it is ensured that as much ozone as possible in the accommodating cavity 211 is collected in the storage element 310, thereby improving the practicality of the dishwasher 10.

[0079] As shown in FIG3 , in one embodiment, the discharge assembly 220 includes a ground electrode 221, a discharge electrode 222, a power source 223 and a glass tube 224. One end of the ground electrode 221 extends into the accommodating cavity 211, and the other end is electrically connected to the power source 223. One end of the glass tube 224 extends into the accommodating cavity 211, and a microporous structure is provided for connecting the inner cavity of the glass tube 224 and the accommodating cavity 211. The discharge electrode 222 is spaced apart from the ground electrode 221, one end of the discharge electrode 222 extends into the glass tube 224 and is located in the accommodating cavity 211, and the other end is electrically connected to the power source 223. The dishwasher 10 also includes a three-way air valve 420, and the three ends of the three-way air valve 420 are respectively connected to the outlet end of the first air pump 230, the second air inlet 312 and the glass tube 224. Thus, when the discharge assembly 220 is discharging, the three-way valve 420 controls the outlet end of the first air pump 230 to be connected to the glass tube 224 and to be isolated from the second air inlet 312. The first air pump 230 works so that the gas in the accommodating chamber 211 can circulate between the water tank 210, the first air pump 230, the three-way valve 420 and the glass tube 224 and be ionized to continuously generate ozone, so that enough ozone can be generated in the water tank 210, thereby improving the reliability of the dishwasher 10. When the discharge assembly 220 is finished discharging, the three-way valve 420 controls the outlet end of the first air pump 230 to be isolated from the glass tube 224 and to be connected to the second air inlet 312. The first air pump 230 works so that the ozone in the water tank 210 is pumped into the storage tank for storage, thereby improving the practicality of the dishwasher 10.

[0080] It should be noted that the first air pump 230 , the three-way air valve 420 and the glass tube 224 are connected in sequence to cooperate to form a circulation pipeline.

[0081] Specifically in this embodiment, the power supply 223 is set as an AC high voltage power supply. The discharge electrode 222 is centrally inserted into the glass tube 224 and is spaced apart from the glass tube 224. The discharge assembly 220 also includes an insulating sealing plug, which fills the gap between the end of the glass tube 224 outside the water tank 210 and the discharge electrode 222, so that the end of the glass tube 224 outside the water tank 210 and the discharge electrode 222 are sealed. The side wall of the end of the glass tube 224 outside the water tank 210 is provided with a connecting branch pipe, and the connecting branch pipe is correspondingly connected to the three-way valve 420.

[0082] As shown in FIG. 1 , in one implementation, the cleaning device 100 includes an inner tank 120 having a first air inlet 121, a water cup assembly 130, a spray arm assembly 140, a washing pump 150, a drain pump 160, a drain pipe 170, and a bowl basket 180. The water cup assembly 130 is sealed and installed at the bottom of the inner tank 120, and is surrounded by the inner tank 120 to form a washing chamber 111. The water cup assembly 130 is provided with a first water inlet 131, a third water inlet 132, a second water outlet 133, and a third water outlet 134 that are connected to the washing chamber 111, and the second water outlet 133 is connected to the water inlet end of the washing pump 150. The water outlet end of the washing pump 150 is connected to the spray arm assembly 140, and the spray arm assembly 140 and the bowl basket 180 are both installed in the washing chamber 111. The third water outlet 134 is connected to the water inlet end of the drain pump 160, and the water outlet end of the drain pump 160 is connected to the drain pipe 170. The dishwasher 10 further includes a three-way water valve 430 and a water inlet solenoid valve 440.
