Description

Technical Field

[0001] This application relates to the field of household appliance technology, specifically to a disinfection system and a dishwasher. Background Technology

[0002] Currently, some dishwashers on the market have sterilization and disinfection functions, such as those using ozone water, ultraviolet light, high-temperature steam, hydrogen peroxide, chlorine dioxide, or sodium hypochlorite. However, these disinfection methods have relatively low efficiency and require a long time. Utility Model Content

[0003] In view of this, this application provides a disinfection system and a dishwasher to solve the technical problems of low disinfection efficiency and long disinfection time in the prior art dishwashers.

[0004] In a first aspect, this application provides a disinfection system, which includes: Multiple disinfection components are used, with the input of each component connected to its corresponding electrolytic solution and the output of each component used to output the produced disinfectant solution. Furthermore, each disinfection component produces a different type of disinfectant solution. The mixing valve has multiple inlets and one outlet. Each inlet is connected to the water source and the output of each disinfection component. Multiple disinfectant solutions are mixed in the mixing valve and the mixed disinfectant solution is output through the outlet.

[0005] Beneficial effects: In this embodiment, by setting up multiple different types of disinfection components and mixing valves, different disinfectants can be mixed, thereby achieving complementary advantages of different disinfectants. For example, the combined action of rapid sterilization and sustained bacteriostatic disinfectants can significantly improve disinfection efficiency. Simultaneously, this embodiment reduces byproducts caused by excessive use of a single disinfectant through the synergistic effect of different disinfectants, thus reducing the generation of toxic and harmful byproducts.

[0006] In one optional implementation, two disinfection components are provided: the first disinfection component is an ozone water generator, and the second disinfection component is a hypochlorous acid water generator.

[0007] Beneficial effects: While ozone water is advantageous for its rapid sterilization and high pathogen elimination efficiency, it lacks sustained disinfection capabilities. Hypochlorous acid water, on the other hand, offers sustained disinfection and produces fewer byproducts. Therefore, this embodiment mixes ozone water and hypochlorous acid water. The resulting disinfectant solution combines rapid sterilization with sustained disinfection, significantly improving the overall performance of the disinfection system.

[0008] In one alternative implementation, the ozone water generator includes: The first water tank is equipped with a first inlet and a first outlet; the first inlet is connected to the electrolytic solution through a first valve, and the first outlet is connected to a mixing valve. A first electrode assembly is disposed in a first water tank; the first electrode assembly includes at least a pair of electrodes and a medium tube sleeved on each electrode. The first power supply has an output side; the output side is connected to each pair of electrodes. The air intake assembly has an air intake side and an air outlet side. The air intake side is connected to the outside, and the air outlet side is located in the first water tank and introduces air into the first water tank. The vent is located on the first water tank.

[0009] In one alternative implementation, the first power source includes: A transformer has a primary side and an output side; A DC voltage source, the first terminal of which is connected to one end of the primary side through a first resistor, and the second terminal of which is connected to the other end of the primary side through a second resistor; The first resonant capacitor is connected in parallel with the first resistor; The second resonant capacitor is connected in parallel with the second resistor; The first resonant switch has one end connected to the first terminal of the DC voltage source and the other end connected to the middle terminal of the primary side. The second resonant switch has one end connected to the second terminal of the DC voltage source, and the other end connected to the middle terminal of the primary side.

[0010] Beneficial Effects: In this embodiment, a resonant circuit can be constructed using the primary side of the transformer, a first resonant capacitor, a second resonant capacitor, a first resonant switch, and a second resonant switch. Since the circuit impedance is lowest and the energy conversion efficiency is highest in the resonant state, DC voltage can be efficiently converted into high-frequency AC power, avoiding power waste. Simultaneously, it ensures that the ozone generation rate meets the standard, supporting rapid sterilization. Furthermore, the first and second resistors protect the resonant capacitors from damage due to overvoltage, improving the overall reliability of the first power supply. Further, the alternating conduction of the first and second resonant switches controls the resonant frequency, matching it to the discharge requirements of the ozone generator and ensuring stable overall equipment operation.

[0011] In one alternative implementation, the first power source further includes: The first current detection module is connected to the output side.

[0012] Beneficial effects: This embodiment can monitor the discharge current in real time through the first current detection module, dynamically feeding back the working status of the ozone generator. When the water level drops, the current detected by the first current detection module decreases regularly. When more air is introduced, resulting in more bubbles, the current will be irregular, and the more bubbles there are, the greater the irregularity. Therefore, technicians or users can use the first current detection module to detect abnormal currents in a timely manner, preventing damage to the power supply or ozone generator, and improving system safety and lifespan.

[0013] In one alternative embodiment, the air outlet side is located at the bottom of the first water tank, and the air outlet side has multiple air outlets, and the projection of the air outlet side completely covers the first electrode assembly in the vertical direction.

[0014] Beneficial effects: In this embodiment, placing the air inlet at the bottom of the water tank allows for a longer contact time between the bubbles and water as they rise from the bottom, resulting in higher air dissolution efficiency. Simultaneously, multiple air outlets ensure a more uniform bubble distribution, preventing uneven discharge caused by localized bubble density or areas without bubbles, thus improving the ozone water production efficiency to some extent. Furthermore, ensuring that the projection of the air outlet completely covers the first electrode assembly ensures that all bubbles pass through the high-voltage discharge area of ​​the first electrode assembly during their ascent, thereby enhancing the ozone water generation efficiency.

[0015] In one alternative embodiment, the hypochlorous acid water generator includes: A container filled with salt water; The second water tank is equipped with a second inlet and a second outlet; the second inlet is connected to the container via a second valve, and the second outlet is connected to a mixing valve. The second electrode assembly includes at least one pair of electrodes, each pair of electrodes extending into the second water tank; The second power supply is equipped with an output port; the output port is connected to each pair of electrodes. The exhaust vent is located on the second water tank.

[0016] In one alternative implementation, the second power source includes: DC voltage source; The full-bridge drive circuit is provided with a control terminal, a first connection terminal, a second connection terminal, and an output port; the control terminal is used to receive drive signals, the first connection terminal is connected to the first terminal of the DC voltage source, the second connection terminal is connected to the second terminal of the DC voltage source, and the output port is connected to the second electrode assembly.

[0017] Beneficial effects: This embodiment can alternately change the direction of current by setting a full-bridge drive circuit, which avoids the electrodes on the second electrode assembly from being covered with scale, thereby maintaining a long-term stable electrolysis efficiency, ensuring a continuous and sufficient production of hypochlorous acid water, and ensuring continuous disinfection capability.

[0018] In one alternative implementation, the second power source further includes: The second current detection module is connected to the second terminal of the DC voltage source.

[0019] Beneficial effects: This embodiment can monitor the electrolysis current in real time through the second current detection module, thereby dynamically adjusting the electrolysis parameters to ensure a stable hypochlorous acid concentration and maintain a continuous disinfection effect. Simultaneously, the second current detection module can promptly detect electrolysis abnormalities, preventing power overload or electrode damage, thus improving the overall reliability of the system.

[0020] In one alternative implementation, the mixing valve is a proportional valve.

[0021] Beneficial effects: By setting the mixing valve as a proportional valve, this embodiment allows users or technicians to precisely control the mixing ratio of various disinfectants according to actual disinfection needs, thus adapting to different disinfection scenarios, such as light pollution, heavy pollution, daily antibacterial, etc., thereby effectively improving the flexibility of the disinfection system and meeting different user needs.

For example, they can refer to fixed communication, detachable communication, or integral communication; they can refer to mechanical communication or electrical communication; they can refer to direct connection or indirect connection through an intermediate medium; they can refer to communication within two components; and they can refer to wireless communication or wired communication. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] Currently, some dishwashers on the market have sterilization and disinfection functions, such as those using ozone water, ultraviolet light, high-temperature steam, hydrogen peroxide, chlorine dioxide, or sodium hypochlorite. However, these disinfection methods have relatively low efficiency and require a long time.

[0029] In view of this, this application provides a disinfection system and a dishwasher to solve the technical problems of low disinfection efficiency and long disinfection time in the prior art dishwashers.

[0030] The following is combined Figures 1 to 3 This describes an embodiment of the present application.

[0031] like Figures 1 to 3 As shown, according to an embodiment of this application, in one aspect, this application provides a disinfection system, which includes a disinfection component 10 and a mixing valve 20.

[0032] Specifically, in this embodiment, multiple disinfection components 10 are provided. The input terminal of each disinfection component 10 is connected to its corresponding electrolytic solution, and the output terminal of each disinfection component 10 is used to output the generated disinfectant water. Each disinfection component 10 produces a different type of disinfectant water. For example, the produced disinfectant water type can be ozone water, sodium hypochlorite solution, etc. Of course, the concentration of the disinfectant water produced by each disinfection component 10 can be the same or different. This embodiment is merely an example of disinfectant water type and concentration, but it is not intended to limit the scope. Those skilled in the art can modify it according to actual conditions, as long as the same technical effect is achieved.

[0033] In this embodiment, when the disinfectant is ozone water, the electrolytic solution can be tap water or softened water that has been filtered. In actual use, because soft water contains fewer impurity ions, less scale is produced during the electrolysis process.

[0034] Of course, this embodiment is merely an example of a specific type of electrolyte solution, but it does not limit the scope of the embodiment. Those skilled in the art can make changes according to the actual situation, as long as the same technical effect can be achieved.

[0035] In this embodiment, when the disinfectant is a sodium hypochlorite solution, the electrolytic solution is a saline solution.

[0036] Furthermore, in this embodiment, the mixing valve 20 is provided with multiple inlet ports 21 and one outlet port 22. Each inlet port 21 is connected to the water source 30 and the output end of each disinfection component 10, respectively. Multiple disinfectant waters are mixed in the mixing valve 20 and the mixed disinfectant water is output to the outside through the outlet port 22.

[0037] In this embodiment, by setting up multiple disinfection components 10 of different types and a mixing valve 20, different disinfectants can be mixed to achieve complementary advantages. For example, rapid sterilization and sustained bacteriostatic disinfectants can work together to significantly improve disinfection efficiency. Simultaneously, this embodiment reduces byproducts caused by excessive use of a single disinfectant through the synergistic effect of different disinfectants, thereby reducing the generation of toxic and harmful byproducts.

[0038] Furthermore, in an optional embodiment, two disinfection components 10 are provided, the first disinfection component 10 being an ozone water generator 11 and the second disinfection component 10 being a hypochlorous acid water generator 12.

[0039] This setup addresses the issue that ozone water, while offering rapid sterilization and high pathogen eradication efficiency, lacks sustained disinfection capabilities. Hypochlorous acid, on the other hand, provides sustained disinfection and produces fewer byproducts. Therefore, this embodiment mixes ozone water and hypochlorous acid water. The resulting disinfectant solution balances rapid sterilization with sustained disinfection, significantly improving the overall performance of the disinfection system.

[0040] Furthermore, in an optional embodiment, the ozone water generator 11 includes a first water tank 111, a first electrode assembly 112, a first power supply 113, an air intake assembly 114, and an exhaust port 115.

[0041] Specifically, in this embodiment, the first water tank 111 is provided with a first inlet 1111 and a first outlet 1112. The first inlet 1111 is connected to the electrolytic solution through a first valve 1113, and the first outlet 1112 is connected to the mixing valve 20. The first valve 1113 can be a solenoid valve or a mechanical valve. Of course, this embodiment is merely an example of the type of the first valve 1113, but it is not a limitation. Those skilled in the art can modify it according to the actual situation, as long as the same technical effect is achieved.

[0042] Furthermore, in this embodiment, the first electrode assembly 112 is disposed in the first water tank 111, and the first electrode assembly 112 includes at least one pair of electrodes and a dielectric tube 116 sleeved on each electrode. The first power supply 113 is provided with an output side, and the output side is connected to each pair of electrodes.

[0043] In this embodiment, the principle of dielectric barrier discharge is utilized to generate a large-area low-temperature plasma at room temperature and pressure, obtaining a large number of active particles conducive to chemical reactions, accompanied by complex physical and chemical processes such as acoustics, light, heat, and electricity. In this embodiment, the dielectric tube 116 can be a glass tube, separating an inner air gap and an outer air gap. The inner air gap is filled with a stainless steel wire mesh placed between the high-voltage electrode and the glass tube. The outer air gap undergoes volumetric corona discharge, while the inner air gap is subjected to near-surface discharge, thereby generating ozone.

[0044] Furthermore, in this embodiment, the air intake assembly 114 is provided with an air intake side and an air outlet side. The air intake side is connected to the outside, and the air outlet side is located in the first water tank 111, allowing air to be introduced into the first water tank 111. The exhaust port 115 is located on the first water tank 111. That is, outside air is discharged into the water in the first water tank 111 through the air intake assembly 114, and air or ozone that is not dissolved in water can be discharged through the exhaust port 115. Of course, during the process of discharging air into the first water tank 111, it will gradually rise to the surface in the form of bubbles, eventually reaching the water surface, and then be discharged from the exhaust port 115.

[0045] Furthermore, in an optional embodiment, the first power supply 113 includes a transformer T1, a DC voltage source DC, a first resonant capacitor C1, a second resonant capacitor C2, a first resonant switch U1, and a second resonant switch U2.

[0046] Specifically, in this embodiment, transformer T1 has a primary side and an output side. The first terminal of the DC voltage source DC is connected to one end of the primary side through a first resistor R1, and the second terminal of the DC voltage source DC is connected to the other end of the primary side through a second resistor R2. The first resonant capacitor C1 is connected in parallel with the first resistor R1, and the second resonant capacitor C2 is connected in parallel with the second resistor R2.

[0047] Furthermore, in this embodiment, one end of the first resonant switch U1 is connected to the first terminal of the DC voltage source DC, and the other end of the first resonant switch U1 is connected to the middle terminal of the primary side. One end of the second resonant switch U2 is connected to the second terminal of the DC voltage source DC, and the other end of the second resonant switch U2 is connected to the middle terminal of the primary side. Both the control terminals of the first resonant switch U1 and the second resonant switch U2 are input with drive signals.

[0048] In this way, when the first resonant switch U1 is turned on, the second resonant capacitor C2 forms a resonant circuit with the lower half-coil on the primary side. When the second resonant switch U2 is turned on, the first resonant capacitor C1 forms a resonant circuit with the upper half-coil on the primary side.

[0049] As for the types of the first resonant switch U1 and the second resonant switch U2, they can be transistors, MOSFETs, or other switching transistors. Of course, this embodiment is merely an example to illustrate the types of the first resonant switch U1 and the second resonant switch U2, but it is not a limitation. Those skilled in the art can make changes according to the actual situation, as long as the same technical effect is achieved.

[0050] In this embodiment, the primary side of transformer T1, the first resonant capacitor C1, the second resonant capacitor C2, the first resonant switch U1, and the second resonant switch U2 form a resonant circuit. Since the circuit impedance is minimum and the energy conversion efficiency is highest in the resonant state, DC voltage can be efficiently converted into high-frequency AC power, avoiding power waste. Simultaneously, it ensures that the ozone generation rate meets the standard, supporting rapid sterilization. Furthermore, the first resistor R1 and the second resistor R2 protect the resonant capacitors from damage due to overvoltage, improving the overall reliability of the first power supply 113. Further, the alternating conduction of the first resonant switch U1 and the second resonant switch U2 controls the resonant frequency, matching it to the discharge requirements of the ozone generator and ensuring stable overall equipment operation.

[0051] Furthermore, in an optional embodiment, the first power supply 113 further includes a first current detection module 117, which is connected to the output side.

[0052] With this configuration, this embodiment can monitor the discharge current in real time through the first current detection module 117, dynamically feeding back the working status of the ozone generator. When the water level drops, the current detected by the first current detection module 117 decreases in a regular pattern. When more air is introduced, resulting in more bubbles, the current will be irregular, and the more bubbles there are, the greater the irregularity. Therefore, technicians or users can use the first current detection module 117 to promptly detect abnormal currents, preventing damage to the power supply or ozone generator and improving system safety and lifespan.

[0053] Furthermore, in an optional embodiment, the air outlet side is located at the bottom of the first water tank 111, and the air outlet side has a plurality of air outlets 1141, and the projection of the air outlet side completely covers the first electrode assembly 112 in the vertical direction.

[0054] With this configuration, placing the air inlet at the bottom of the water tank allows for a longer contact time between the bubbles and water as they rise from the bottom, resulting in higher air dissolution efficiency. Simultaneously, multiple air outlets 1141 ensure a more uniform bubble distribution, preventing uneven discharge caused by localized bubble density or areas without bubbles, thus improving the ozone water production efficiency to some extent. Furthermore, ensuring that the projection of the air outlet completely covers the first electrode assembly 112 ensures that all bubbles pass through the high-voltage discharge area of ​​the first electrode assembly 112 during their ascent, thereby enhancing the ozone water generation efficiency.

[0055] Furthermore, in an optional embodiment, the hypochlorous acid water generator 12 includes a container 121, a second water tank 122, a second electrode assembly 123, a second power supply 124, and an exhaust port 125.

[0056] Specifically, in this embodiment, the container 121 contains saline solution, but saline solution can also be contained in other devices. This embodiment is merely an example.

[0057] Furthermore, the second water tank 122 is provided with a second inlet 1221 and a second outlet 1222. The second inlet 1221 is connected to the container 121 through a second valve 1223, and the second outlet 1222 is connected to the mixing valve 20. The second valve 1223 can be a solenoid valve or a mechanical valve. Of course, this embodiment is merely an example of the type of the second valve 1223, but it is not intended to limit it. Those skilled in the art can modify it according to actual conditions, as long as the same technical effect is achieved.

[0058] Furthermore, in this embodiment, the second electrode assembly 123 includes at least one pair of electrodes, each pair extending into the second water tank 122. The second power supply 124 is provided with an output port, which is connected to each pair of electrodes. An exhaust port 125 is formed on the second water tank 122.

[0059] In actual operation, the second electrode assembly 123 is used to electrolyze brine to generate sodium hypochlorite solution. The second power supply 124 can be either AC or DC, capable of providing high-voltage power so that the second electrode assembly 123 can discharge at high voltage. Waste gas or harmful gases generated during electrolysis can be discharged through the waste gas port 125.

[0060] Furthermore, in an alternative embodiment, the second power supply 124 includes a DC voltage source DC and a full-bridge drive circuit H.

[0061] Specifically, the full-bridge drive circuit H is provided with a control terminal, a first connection terminal, a second connection terminal, and an output port. The control terminal is used to receive drive signals; for example, the drive signal can be output by a separate controller or by the controller inside a household appliance equipped with the disinfection system. This embodiment is merely illustrative. Further, the first connection terminal is connected to the first terminal of the DC voltage source DC, the second connection terminal is connected to the second terminal of the DC voltage source DC, and the output port is connected to the second electrode assembly 123.

[0062] like Figure 3 As shown, the full-bridge drive circuit H includes a first switch Q1, a second switch Q2, a third switch Q3, and a fourth switch Q4. The control terminals of the first switch Q1, second switch Q2, third switch Q3, and fourth switch Q4 are all used to receive control signals. The first terminal of the first switch Q1 is connected to the positive terminal of the DC voltage source DC, and the second terminal of the first switch Q1 is connected to the first plate of the second electrode assembly 123. The first terminal of the second switch Q2 is connected to the positive terminal of the DC voltage source DC, and the second terminal of the second switch Q2 is connected to the second plate of the second electrode assembly 123. The first terminal of the third switch Q3 is connected to the negative terminal of the DC voltage source DC, and the second terminal of the third switch Q3 is connected to the first plate of the second electrode assembly 123. The first terminal of the fourth switch Q4 is connected to the negative terminal of the DC voltage source DC, and the second terminal of the fourth switch Q4 is connected to the second plate of the second electrode assembly 123.

[0063] Therefore, in this embodiment, the full-bridge drive circuit H has two conduction modes. In the first conduction mode, the output port is forward-biased, allowing current to flow through the output port in the forward direction. The first electrode in the second electrode assembly 123 is the positive electrode, and the second electrode is the negative electrode. In the second conduction mode, the output port is reverse-biased, allowing current to flow through the output port in the reverse direction. The first electrode in the second electrode assembly 123 is the negative electrode, and the second electrode is the positive electrode.

[0064] With this configuration, this embodiment can alternately change the direction of current by setting the full-bridge drive circuit H, avoiding the scale buildup on the electrodes of the second electrode assembly 123, thereby maintaining a long-term stable electrolysis efficiency, ensuring a continuous and sufficient generation of hypochlorous acid water, and ensuring continuous disinfection capability.

[0065] Furthermore, in an optional embodiment, the second power supply 124 further includes a second current detection module 126, which is connected to the second terminal of the DC voltage source DC.

[0066] With this configuration, the second current detection module 126 in this embodiment can monitor the electrolysis current in real time, thereby dynamically adjusting the electrolysis parameters to ensure a stable hypochlorous acid concentration and maintain a continuous disinfection effect. Simultaneously, the second current detection module 126 can promptly detect electrolysis abnormalities, preventing power overload or electrode damage and improving the overall reliability of the system.

[0067] Furthermore, in an alternative embodiment, the mixing valve 20 is a proportional valve.

[0068] With this configuration, this embodiment sets the mixing valve 20 as a proportional valve, allowing users or technicians to precisely control the mixing ratio of various disinfectants according to actual disinfection needs. This adapts to different disinfection scenarios, such as light pollution, heavy pollution, and daily antibacterial treatment, thereby effectively improving the flexibility of the disinfection system and meeting different user needs.

[0069] Secondly, this application provides a dishwasher that includes a disinfection system as described in any of the above embodiments.
