Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a disinfectant preparation device and a dishwasher. Background Technology

[0002] Plasma technology, used for sterilization in dishwashers, is an emerging and cutting-edge technology. It boasts excellent sterilization performance and high efficiency, leading to its widespread application in dishwashers. However, the process of preparing the disinfectant solution using plasma technology involves ionizing the liquid with high voltage, creating charged liquid. As this charged liquid flows through the dishwasher's pipes, it can cause the entire water system and internal structure to become electrified, increasing the risk of electric shock. Utility Model Content

[0003] This application addresses the risk of electric shock during the use of existing dishwashers by proposing a disinfectant preparation device and a dishwasher. This disinfectant preparation device and dishwasher have the technical effect of reducing the charge carried by the internal water system and structure of the dishwasher, thereby reducing the risk of electric shock to users.

[0004] In a first aspect, embodiments of this application provide a disinfectant preparation apparatus, comprising:

[0005] Water tank with a water outlet;

[0006] A plasma generating mechanism is located inside the water tank. The plasma generating mechanism is used to generate plasma by discharge. The plasma can dissolve in the water in the water tank to form a disinfectant solution, which flows out through the water outlet.

[0007] An anti-electric component is installed at the water outlet and is used to neutralize the charge in the disinfectant.

[0008] The disinfectant preparation device of this application is commonly used in dishwashers to improve their cleaning capabilities. When the disinfectant flows through the anti-electric component to other water systems or components of the dishwasher, it reduces the probability of charge transfer from the disinfectant to the areas it flows through, thus preventing the water system or internal structures of the dishwasher from becoming electrified. Therefore, it reduces the probability of electric shock for the user and improves the safety of using the dishwasher.

[0009] In one embodiment, the anti-electric shock component includes a first sub-anti-electric shock component and a second sub-anti-electric shock component, wherein the first sub-anti-electric shock component is installed at the water outlet;

[0010] The water tank has an air outlet, the plasma generating mechanism has an air inlet, the disinfectant preparation device further includes a gas return pipe, the gas return pipe is connected between the air inlet and the air outlet, and the air outlet is provided with a second sub-anti-electric component.

[0011] In this way, the gas generated during ionization can be recycled through the gas return pipe, reducing the probability of gas leakage into the outside world and thus harming human health. Because the gas is recycled and partially dissolved in the disinfectant, the second anti-electric component reduces the charge in the gas, thereby reducing the charge in the disinfectant and further reducing electrical hazards.

[0012] In one embodiment, the disinfectant preparation device further includes a heat exchanger and a gas-liquid separator connected together. The heat exchanger and the gas-liquid separator are installed on the gas return pipe and are connected between the air inlet and the air outlet.

[0013] The heat exchanger is located near the air outlet and is used to connect to an external water source.

[0014] Because the gas return pipe is connected to the heat exchanger, and the heat exchanger is filled with a cryogenic liquid, the gas-liquid mixture can exchange heat as it flows through the heat exchanger, thus condensing into condensate. Furthermore, the outlet of the heat exchanger is connected to a gas-liquid separator, so both the condensed gas and the initial gas entering the gas return pipe are separated from the condensate by the gas-liquid separator, and all flow towards the inlet. In addition, the ambient temperature gas obtained after heat exchange carries a relatively small amount of charge, further reducing the amount of charge in the gas flowing back to the plasma generator, thereby reducing the amount of charge in the disinfectant water.

[0015] In one embodiment, the disinfectant preparation device further includes a liquid return pipe, one end of which is connected to the gas-liquid separator and the other end of which is connected to the water tank.

[0016] After the gas-liquid mixture and the initial gas entering the gas return pipe exchange heat through the heat exchanger, condensate and room-temperature gas are obtained. The condensate and room-temperature gas are then separated after flowing together through the gas-liquid splitter. All the gas flows to the gas return pipe, thus returning to the plasma generator. The condensate flows to the liquid return pipe, thus returning to the water tank. This configuration allows the obtained condensate to be channeled into the water tank for recycling.

[0017] In one embodiment, the anti-electric shock component further includes a third sub-anti-electric shock component, which is disposed on the liquid return pipe.

[0018] When the condensate flows out from the gas-liquid separator and into the liquid return pipe, it passes through the third sub-anti-electric component, which neutralizes the charge in the condensate, thereby reducing the charge in the condensate and thus reducing the charge in the disinfectant in the water tank, further improving the safety of the dishwasher.

[0019] In one embodiment, the disinfectant preparation device further includes an external pipe and a water pipe insulation component. The external pipe is installed on the heat exchange component and is used to connect to an external water source. The water pipe insulation component is installed on the external pipe.

[0020] Users can inject cryogenic liquid into the heat exchanger as a heat exchange medium by connecting an external pipe to a water source. The connection between the external pipe and the heat exchanger can be, but is not limited to, threaded connections or snap-fit ​​connections, facilitating assembly. Furthermore, if either the heat exchanger or the external pipe is damaged, only the damaged component needs to be replaced. Replacing only the damaged component, rather than replacing both the external pipe and the heat exchanger together, reduces maintenance costs. Installing water pipe insulation on the external pipe provides electrical insulation, thermal insulation, support, and shock absorption, thereby extending the service life of the heat exchanger.

[0021] In one embodiment, the plasma generating mechanism includes a discharge electrode, a ground electrode, and a dielectric tube. The discharge electrode and the ground electrode are both used to connect to an external power source. The discharge electrode is located inside the dielectric tube and is used to discharge and generate the plasma. The dielectric tube is provided with the air inlet.

[0022] A dielectric tube containing a discharge electrode is inserted into a water tank, with a portion of the tube immersed in the liquid. The ground electrode and discharge electrode are spaced apart and both are electrically connected to a high-voltage AC power source. When the plasma generator is operating, the discharge electrode performs dielectric barrier discharge within the dielectric tube to generate plasma. This configuration simplifies the structure of the plasma generator and facilitates its fabrication.

[0023] In one embodiment, there are multiple dielectric tubes, which are distributed at intervals, and each dielectric tube corresponds to a discharge electrode.

[0024] When the plasma generator is running, four discharge electrodes operate simultaneously, which can ionize the liquid in different areas of the water tank, thus generating a large amount of plasma and improving the preparation efficiency of the disinfectant.

[0025] In one embodiment, the wall of the medium tube is provided with a through hole, which communicates with the water tank.

[0026] This design not only reduces the probability of the medium pipe rupturing or overflowing due to a large amount of gas accumulating inside, but also enables the gas to be recycled.

[0027] Secondly, embodiments of this application provide a dishwasher, including the disinfectant preparation apparatus as described above.

[0028] When the dishwasher is running, the disinfectant preparation device begins to prepare disinfectant solution. The device works as follows: the discharge electrode performs a dielectric barrier discharge inside the dielectric tube, generating plasma. The plasma can enter the water tank through the through-hole of the dielectric tube and dissolve in the water, thus forming disinfectant solution. The disinfectant solution flows through the outlet to the location of the dishes in the dishwasher. As the disinfectant solution flows through the outlet, an anti-static component neutralizes at least some of the charge in the disinfectant solution, reducing its electrical charge.

[0029] During ionization, the gas and gas-liquid mixture that are not dissolved in the water are discharged from the water tank's outlet and enter the gas return pipe. In the initial stage of entering the gas return pipe, the gas and gas-liquid mixture can be neutralized by the second sub-electrostatic device to reduce the charge on the gas and gas-liquid mixture.

[0030] Subsequently, the gas and gas-liquid mixture undergo heat exchange through a heat exchanger. The gas-liquid mixture is condensed to form condensate, while the gas becomes room temperature gas. After exiting the heat exchanger, the condensate and room temperature gas are separated by a gas-liquid separator, with all the gas flowing towards the inlet. All the gas flows to the gas return pipe, thus returning to the plasma generator, while the condensate flows to the liquid return pipe and back to the water tank. During its flow through the liquid return pipe, the condensate passes through a third-level anti-electric component, where its charge is neutralized, reducing the charge on the condensate returning to the water tank.

[0031] In summary, by incorporating multiple sub-anti-electric shock components, the probability of charge transfer from the disinfectant to the areas it flows through, thereby electrifying the dishwasher's water system or some internal structures, is reduced. Therefore, this lowers the risk of electric shock for users and improves the dishwasher's safety. Attached Figure Description

[0043] Please see Figure 1 One embodiment of this application provides a disinfectant preparation device 100, which includes a water tank 10, a plasma generating mechanism 20, and an anti-electric shock component 30. The water tank 10 has a water outlet 11; the plasma generating mechanism 20 is located inside the water tank 10 and is used to generate plasma by discharge. The plasma can dissolve in the water in the water tank 10 to form a disinfectant, which flows out through the water outlet 11; the anti-electric shock component 30 is installed at the water outlet 11 and is used to neutralize the charge in the disinfectant.

[0044] The water tank 10 has a closed water storage chamber, and the water outlet 11 is located at the bottom of the water tank 10. A valve or other switch is typically installed at the water outlet 11. During the preparation of the disinfectant solution, the valve is normally closed, preventing the liquid in the water tank 10 from flowing out through the water outlet 11. When the disinfectant solution is ready for use, the valve is opened, and the disinfectant solution flows through the water outlet 11 to the location of the dishes in the dishwasher.

[0045] The plasma generating mechanism 20 adopts the glow discharge principle, that is, the plasma generating mechanism 20 uses high voltage discharge to generate plasma in the water tank 10 (liquid phase environment). During the discharge, the high-energy electrons generated around the gas / liquid interface react violently with air and water molecules, thereby generating strong oxidizing substances such as hydroxyl radicals and H2O2, producing a solution with the ability to disinfect bacteria and viruses, that is, disinfectant.

[0046] The anti-electric component 30 has a large internal resistance. Because the disinfectant solution will carry a large amount of charge during the preparation process, the anti-electric component 30 is installed at the outlet 11. When the disinfectant solution flows through the outlet 11, the anti-electric component 30 can neutralize at least part of the charge in the disinfectant solution, thereby reducing the degree of charge on the disinfectant solution.

[0047] The aforementioned disinfectant preparation device 100 is typically used in dishwashers to improve their cleaning capabilities. When the disinfectant flows through the anti-electric component 30 to other water systems or components of the dishwasher, it reduces the probability of charge transfer from the disinfectant to the areas it flows through, thus preventing the water system or internal structures of the dishwasher from becoming electrified. Therefore, it reduces the probability of electric shock for the user and improves the safety of using the dishwasher.

[0048] Furthermore, in some embodiments, the anti-electric component 30 includes a first sub-anti-electric component 31 and a second sub-anti-electric component 32. The first sub-anti-electric component 31 is installed at the water outlet 11. The water tank 10 has an air outlet 12, the plasma generating mechanism 20 has an air inlet 21, and the disinfectant preparation device 100 also includes a gas return pipe 40, which is connected between the air inlet 21 and the air outlet 12. The air outlet 12 is provided with the second sub-anti-electric component 32.

[0049] The first sub-anti-electric shock component 31 and the second sub-anti-electric shock component 32 have similar structures and functions, both used to neutralize electric charge. Since the plasma generator 20 produces gases such as ozone and nitrogen oxides during ionization, these gases, if leaked to the outside, could affect human health. Therefore, a gas return pipe 40 is installed between the water tank 10 and the plasma generator 20. Gases such as ozone and nitrogen oxides produced during ionization can flow into the gas return pipe 40 through the outlet 12, then flow to the inlet 21, and finally flow back to the plasma generator 20, where they are ionized. Specifically, after the ozone and other gases flow through the inlet 21, they can be neutralized by the second sub-anti-electric shock component 32, thus reducing the amount of charge in the gas.

[0050] In this way, the gas generated during ionization can be recycled through the gas return pipe 40, reducing the probability of gas leakage to the outside world and thus harming human health. Because the gas is recycled and partially dissolved in the disinfectant, the second anti-electric component 32 reduces the amount of charge in the gas, thereby reducing the amount of charge in the disinfectant and further reducing electrical hazards.

[0051] Furthermore, in some embodiments, the disinfectant preparation device 100 also includes a heat exchanger 50 and a gas-liquid separator 60 connected to each other. The heat exchanger 50 and the gas-liquid separator 60 are installed on the gas return pipe 40 and are connected between the air inlet 21 and the air outlet 12. The heat exchanger 50 is located near the air outlet 12 and is used to connect to an external water source.

[0052] The heat exchanger 50 can be a plate heat exchanger. The heat exchanger 50 can be activated when the plasma generating mechanism 20 is running. During ionization in the plasma generating mechanism 20, what is actually produced is gaseous ozone and a gas-liquid mixture containing active oxides and active nitrogen. The gas and gas-liquid mixture flow into the gas return pipe 40.

[0053] Because the gas return pipe 40 is connected to the heat exchanger 50, and the heat exchanger 50 is filled with a cryogenic liquid, the gas-liquid mixture can exchange heat as it flows through the heat exchanger 50, thus condensing into condensate. Furthermore, the outlet of the heat exchanger 50 is connected to a gas-liquid separator 60, so both the condensed gas and the initial gas entering the gas return pipe 40 can be separated from the condensate by the gas-liquid separator 60, and thus all flow to the inlet 21. In addition, the ambient temperature gas obtained after heat exchange carries a relatively small amount of charge, which further reduces the amount of charge in the gas flowing back to the plasma generator 20, thereby reducing the amount of charge in the disinfectant water.

[0054] In some embodiments, the disinfectant preparation device 100 further includes a liquid return pipe 70, one end of which is connected to the gas-liquid separator 60 and the other end is connected to the water tank 10.

[0055] After the gas-liquid mixture and the initial gas entering the gas return pipe 40 exchange heat through the heat exchanger 50, condensate and room-temperature gas are obtained. The condensate and room-temperature gas are separated after flowing together through the gas-liquid splitter pipe. All the gas flows to the gas return pipe 40, and then back to the plasma generator 20. The condensate flows to the liquid return pipe 70, and then back to the water tank 10.

[0056] With this setup, the obtained condensate can be introduced into the water tank 10 for recycling.

[0057] In some embodiments, the anti-electric shock component 30 further includes a third sub-anti-electric shock component 33, which is disposed on the liquid return pipe 70.

[0058] The structure and function of the third sub-anti-electric shock component 33 are similar to those of the two sub-anti-electric shock components 30 mentioned above. The third sub-anti-electric shock component 33 can be installed close to the gas-liquid diversion component 60.

[0059] When the condensate flows out from the gas-liquid separator 60 and into the liquid return pipe 70, the condensate can pass through the third sub-anti-electric component 33. The third sub-anti-electric component 33 can neutralize the charge in the condensate to reduce the amount of charge in the condensate, thereby reducing the amount of charge in the disinfectant in the water tank 10, and further improving the safety of the dishwasher.

[0060] like Figure 2 As shown, in some embodiments, the disinfectant preparation device 100 further includes an external pipe 80 and a water pipe insulator 90. The external pipe 80 is installed on the heat exchanger 50 and is used to connect to an external water source. The water pipe insulator 90 is installed on the external pipe 80.

[0061] Users can inject cryogenic liquid into the heat exchanger 50 as a heat exchange medium by connecting the external pipe 80 to a water source. The connection between the external pipe 80 and the heat exchanger 50 can be, but is not limited to, threaded connections or snap-fit ​​connections, to facilitate assembly. Furthermore, if either the heat exchanger 50 or the external pipe 80 is damaged, the damaged component can be replaced with a new one. Replacing only the damaged component, rather than replacing both the external pipe 80 and the heat exchanger 50, reduces maintenance costs.

[0062] Of course, the external pipe 80 can also be fixed on the heat exchanger 50, and no specific limitation is made here.

[0063] Secondly, the water pipe insulation component 90 can also be installed on the external pipe 80 via threaded connection, adhesive bonding, or other methods. If either the water pipe insulation component 90 or the external pipe 80 is damaged, the damaged component can be replaced with a new one. Replacing only the damaged component, rather than replacing both the external pipe 80 and the water pipe insulation component 90, reduces maintenance costs.

[0064] As for installing water pipe insulation component 90 on external pipe 80, it can achieve electrical insulation, heat insulation, support and fixation and buffering and shock absorption, thereby extending the service life of heat exchange component 50.

[0065] like Figure 3 As shown, in some embodiments, the plasma generating mechanism 20 includes a discharge electrode 22, a ground electrode 23 and a dielectric tube 24. The discharge electrode 22 and the ground electrode 23 are both used to connect to an external power source. The discharge electrode 22 is located inside the dielectric tube 24 and is used to discharge and generate plasma. The dielectric tube 24 is provided with an air inlet 21.

[0066] The dielectric tube 24 is made of an insulating tube, such as a glass tube or a ceramic tube. The structure of the dielectric tube 24 is similar to that of a test tube. The dielectric tube 24 contains a discharge electrode 22, and the opening of the dielectric tube 24 is configured as an air inlet 21.

[0067] A dielectric tube 24 containing a discharge electrode 22 is inserted into a water tank 10, with a portion of the dielectric tube 24 immersed in the liquid within the tank 10. A ground electrode 23 is spaced apart from the discharge electrode 22, and both are electrically connected to a high-voltage alternating current. When the plasma generator is operating, the discharge electrode 22 performs dielectric barrier discharge within the dielectric tube 24 to generate plasma.

[0068] This design simplifies the structure of the plasma generating mechanism and makes it easier to manufacture.

[0069] Specifically, there are multiple dielectric tubes 24, which are distributed at intervals, and each dielectric tube 24 corresponds to a discharge electrode 22.

[0070] For example, in Figure 1 In the illustrated configuration, there are four dielectric tubes 24, therefore, there are also four discharge electrodes 22. All four dielectric tubes 24 are connected to the gas return pipe 40.

[0071] When the plasma generator 20 is running, the four discharge electrodes 22 operate simultaneously, which can ionize the liquid in different areas of the water tank 10, thereby generating a large amount of plasma and improving the preparation efficiency of the disinfectant.

[0072] It is understandable that the number of dielectric tubes 24 and corresponding discharge electrodes 22 can be determined according to the actual situation, and no specific limitation is made here. Moreover, by setting a control component, the number of discharge electrodes 22 that can operate simultaneously can also be controlled to obtain the required amount of disinfectant solution, thereby improving the operational flexibility of the plasma generating mechanism 20.

[0073] More specifically, in some embodiments, the wall of the medium tube 24 is provided with a through hole 241, which communicates with the water tank 10.

[0074] For example, the bottom of the medium tube 24 is provided with a through hole 241. The through hole 241 connects the medium tube 24 and the water tank 10. The plasma in the medium tube 24 can enter the water tank 10 through the through hole 241 and dissolve in the water to form a disinfectant. The gas that is not dissolved in the water is discharged from the gas outlet 12 of the water tank 10 to circulate the gas.

[0075] This design not only reduces the probability of the medium pipe 24 rupturing or overflowing due to a large amount of gas accumulating inside, but also enables the gas to be recycled.

[0076] In addition, this application also provides a dishwasher, which includes the disinfectant preparation device 100 in the above embodiments.

[0077] When the dishwasher is running, the disinfectant preparation device 100 begins to prepare disinfectant solution. The disinfectant preparation device 100 operates as follows: the discharge electrode 22 performs dielectric barrier discharge within the dielectric tube 24, generating plasma. The plasma can enter the water tank 10 through the through-hole 241 of the dielectric tube 24 and dissolve in the water, thus forming disinfectant solution. The disinfectant solution flows through the outlet 11 to the location of the dishes in the dishwasher. As the disinfectant solution flows through the outlet 11, the anti-static component 30 neutralizes at least a portion of the charge in the disinfectant solution, reducing its electrical charge.

[0078] During ionization, the gas and gas-liquid mixture that are not dissolved in water are discharged from the outlet 12 of the water tank 10 and enter the gas return pipe 40. In the initial stage of entering the gas return pipe 40, the gas and gas-liquid mixture can be neutralized by the second sub-anti-electric component 32 to reduce the charge of the gas and gas-liquid mixture.

[0079] Subsequently, the gas and gas-liquid mixture undergo heat exchange through heat exchanger 50. The gas-liquid mixture can be condensed to form condensate, while the gas becomes room temperature gas. After exiting heat exchanger 50, the condensate and room temperature gas are separated by gas-liquid separator 60, with all the gas flowing towards inlet 21. All the gas flows to gas return pipe 40, thus returning to plasma generator 20, while the condensate flows to liquid return pipe 70 and back to water tank 10. When the condensate flows through liquid return pipe 70, it passes through third sub-anti-electric component 33 and is neutralized by the third sub-anti-electric component 33, reducing the charge of the condensate returning to water tank 10.

[0080] In summary, by incorporating multiple sub-anti-electric shock components 30, the probability of charge transfer from the disinfectant to the areas it flows through, thereby electrifying the dishwasher's water system or some internal structures, is reduced. Therefore, this lowers the risk of electric shock for users and improves the dishwasher's safety.

[0081] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
