[0031] The third pipeline is provided at the bottom of the inner container, and the electrolytic disinfection module and the water cup are respectively provided on both sides of the third pipeline.

[0032] The technical solution of the present invention has the following advantages:

[0033] 1. The present invention provides an electrolytic disinfection module, comprising: a housing, an electrolytic chamber is provided inside the housing, and an electrolytic water inlet and an electrolytic water outlet communicating with the electrolytic chamber are provided on the housing; an electrode assembly, including a first electrode and a second electrode provided on the housing; a salt feeding mechanism, including a salt feeding pipe, and the salt feeding pipe communicates with the electrolytic chamber.

[0034] The electrolyte solution is injected into the electrolytic disinfection module through the salt feeding mechanism. After the electrolyte solution enters the electrolytic disinfection module, disinfected water is prepared by electrolysis. The disinfected water enters the inner tank to disinfect the tableware in the inner tank. Thus, the tableware can be disinfected inside the dishwasher. At the same time, the disinfected water will disinfect the internal structures of the dishwasher such as the pipeline assembly, the inner tank, and the electrolytic disinfection module through the pipeline. Therefore, even if there is residual disinfected water in the internal structure of the dishwasher after the disinfection treatment, bacteria will not breed and unpleasant odors are not easily generated. Among them, salt can also be fed into the pipeline assembly upstream of the electrolytic chamber or other components through which water flows by the salt feeding mechanism. When the water enters the electrolytic disinfection module, it contacts the salt to dissolve the salt sufficiently to form an electrolyte solution. The electrolyte solution further flows into the electrolytic disinfection module and disinfected water is prepared by electrolysis.

[0035] 2. For the electrolytic disinfection module provided by the present invention, a salt feeding device is detachably provided at the salt feeding port.

[0036] The specific form of the salt feeding device can be a salt feeding box. The salt feeding box is detachably connected to the salt feeding pipe. By disassembling the salt feeding box, salt is replenished into the salt feeding box. Thus, after the salt feeding box is installed, salt is replenished into the salt feeding pipe and the electrolytic disinfection module by the salt feeding box.

[0037] 3. For the electrolytic disinfection module provided by the present invention, the housing includes: a first housing, the first electrode is provided on the first housing, and a first bridge circuit structure is provided on the outside of the first housing; a second housing, the second electrode is provided on the second housing, and a second bridge circuit structure is provided on the outside of the second housing.

[0038] The first electrode and the second electrode are respectively powered on through the first bridge circuit structure and the second bridge circuit structure, so that the first electrode and the second electrode become the anode and the cathode in the electrolysis process. On the other hand, the separately arranged first housing and second housing can be independently manufactured during the manufacturing process. The cathode circuit and the anode circuit are completely independent and not easily mixed. On the one hand, the manufacturing efficiency is improved, and on the other hand, the efficiency of subsequent assembly and installation is improved.

[0039] 4. For the electrolytic disinfection module provided by the present invention, both the first electrode and the second electrode are sheet-shaped metal plates.

[0040] During the electrolysis process, the sheet-shaped metal plate can increase the contact area between the electrode and the electrolyte solution, thereby improving the electrolysis efficiency.

[0041] 5. The electrolytic disinfection module provided by the present invention is provided with a reduced-diameter portion at the positions where the electrolytic water inlet and the electrolytic water outlet are located, and the inner diameter of the channel of the reduced-diameter portion gradually increases along the direction of entering the electrolytic chamber.

[0042] The inner wall of the reduced-diameter portion is a conical surface. The reduced-diameter portion on the side of the electrolytic water inlet has a guiding effect, which can fully guide the incoming water flow into the electrolytic chamber and diffuse it, so that the water flow passes through the channel between the second electrodes more evenly. The reduced-diameter portion on the side of the electrolytic water outlet can pressurize the disinfected water about to flow out of the electrolytic chamber and increase the pressure of the disinfected water flowing out.

[0043] 6. The electrolytic disinfection module provided by the present invention, the first housing and the second housing are connected by welding, and the welding surface of the first housing and / or the second housing is a stepped surface structure.

[0044] The stepped surface structure can, on the one hand, facilitate the installation and positioning of the first housing and the second housing, and on the other hand, increase the contact area between the first housing and the second housing during welding and improve the welding strength.

[0057] Embodiment 1

[0058] This embodiment provides an electrolytic disinfection module 2, as Figures 3 - 5As shown in the figure, it includes: a housing, an electrolysis chamber 25 is provided inside the housing, and an electrolysis water inlet 242 and an electrolysis water outlet 243 communicating with the electrolysis chamber 25 are provided on the housing; an electrode assembly, including a first electrode 231 and a second electrode 241 provided on the housing; a salt feeding mechanism, including a salt feeding pipe 3, and the salt feeding pipe 3 communicates with the electrolysis chamber 25.

[0059] The electrolyte solution is injected into the electrolytic disinfection module 2 through the salt feeding mechanism. After the electrolyte solution enters the electrolytic disinfection module 2, disinfected water is prepared by electrolysis. The disinfected water enters the inner tank 1 to disinfect the tableware in the inner tank 1. Thus, the tableware can be disinfected inside the dishwasher. At the same time, the disinfected water will disinfect the internal structures of the dishwasher such as the pipeline assembly, the inner tank 1, and the electrolytic disinfection module 2 through the pipeline. Therefore, even if there is residual disinfected water in the internal structure of the dishwasher after the disinfection treatment, bacteria will not breed and unpleasant odors are not likely to be generated. Among them, salt can also be put into the pipeline assembly upstream of the electrolysis chamber 25 or other components through which water flows by the salt feeding mechanism, and the salt is fully dissolved when the water contacts the salt when entering the electrolytic disinfection module 2 to form an electrolyte solution. The electrolyte solution further flows into the electrolytic disinfection module 2 and disinfected water is prepared by electrolysis.

[0060] On the basis of the above embodiment, as a further limited embodiment, as Figure 1 , Figure 2 shown, at least one salt feeding port is provided on the salt feeding pipe 3.

[0061] On the basis of the above embodiment, as a further limited embodiment, a salt feeding device is detachably provided on the salt feeding port. The specific form of the salt feeding device can be a salt feeding box, and the salt feeding box is detachably connected to the salt feeding pipe 3. The salt feeding box is disassembled to supplement salt into the salt feeding box, so that after the salt feeding box is installed, the salt feeding box supplements salt to the salt feeding pipe 3 and the electrolytic disinfection module 2.

[0062] On the basis of the above embodiment, as a further limited embodiment, as Figures 3 - 5 shown, the housing includes: a first housing 23, the first electrode 231 is provided on the first housing 23, and a first bridge circuit structure is provided on the outside of the first housing 23; a second housing 24, the second electrode 241 is provided on the second housing 24, and a second bridge circuit structure 245 is provided on the outside of the second housing 24.

[0063] The first electrode 231 and the second electrode 241 are respectively powered on through the first bridge circuit structure and the second bridge circuit structure 245, so that the first electrode 231 and the second electrode 241 become the anode and cathode in the electrolysis process. As Figure 3As shown, both the first bridge circuit structure and the second bridge circuit structure 245 are provided with blade structures or terminal structures for power connection. On the other hand, the separately arranged first housing 23 and second housing 24 can be independently manufactured during the manufacturing process. The cathode circuit and the anode circuit are completely independent and not easily misconnected, which improves the manufacturing efficiency on the one hand and the efficiency of subsequent assembly and installation on the other hand.

[0064] On the basis of the above embodiments, as a further limited embodiment, as Figure 4 , Figure 5 shown, both the first electrode 231 and the second electrode 241 are sheet metal plates.

[0065] During the electrolysis process, the sheet metal plate can increase the contact area between the electrode and the electrolyte solution, thereby improving the electrolysis efficiency. As an alternative embodiment, the first electrode 231 and / or the second electrode 241 is a columnar structure or a curved or wavy structure.

[0066] On the basis of the above embodiments, as a further limited embodiment, as Figure 4 , Figure 5 shown, there are multiple first electrodes 231 and multiple second electrodes 241, and two second electrodes 241 are arranged on both sides of each first electrode 231. As an alternative embodiment, multiple first electrodes are arranged between the two second electrodes 241. As another alternative embodiment, the first electrode 231 and the second electrode 241 are respectively arranged on both sides of the electrolysis chamber 25.

[0067] On the basis of the above embodiments, as a further limited embodiment, as Figure 4 shown, both the electrolysis water inlet 242 and the electrolysis water outlet 243 are arranged on the second housing 24. The water flow at the electrolysis water inlet 242 and the electrolysis water outlet 243 is more turbulent, and arranging them on the second housing 24 can prevent the turbulent water flow from impacting the joint part of the first housing 23 and the second housing 24.

[0068] On the basis of the above embodiments, as a further limited embodiment, as Figure 3 , Figure 4 shown, the electrolysis water inlet 242 and the electrolysis water outlet 243 are respectively arranged on two opposite side surfaces of the second housing 24. The channel between the electrode plates is parallel to the connection line of the electrolysis water inlet 242 and the electrolysis water outlet 243. Therefore, the channel between the electrode plates is parallel to the water flow direction, and the water flow can impact the surface of the electrode plates to achieve self-cleaning of the electrode plate surface. On the other hand, as Figure 1 , Figure 4As shown, the salt feeding pipe 3 communicates with the electrolysis chamber 25, and the opening of the electrolysis chamber 25 faces the second electrode 241 directly. When the water flow enters the electrolysis chamber 25 through the second pipe, it can directly flush away the salt accumulated near the salt feeding pipe 3, so as to dissolve it fully in the electrolysis chamber 25.

[0069] On the basis of the above - mentioned embodiment, as a further - defined embodiment, as Figure 3 、 Figure 4 shown, a diameter - varying part 244 is provided at the position where the electrolysis water inlet 242 and the electrolysis water outlet are located. The inner - diameter of the channel of the diameter - varying part 244 gradually increases along the direction of entering the electrolysis chamber 25. The inner wall of the diameter - varying part 244 is a conical surface. The diameter - varying part 244 on the side of the electrolysis water inlet 242 has a guiding function, which can fully guide and diffuse the incoming water flow into the electrolysis chamber 25, so that the water flow passes through the channels between the second electrodes 241 more evenly. The diameter - varying part 244 on the side of the electrolysis water outlet 243 can pressurize the disinfected water about to flow out of the electrolysis chamber 25, and increase the pressure of the disinfected water flowing out.

[0070] On the basis of the above - mentioned embodiment, as a further - defined embodiment, as Figure 3 、 Figure 4 shown, the first housing 23 and the second housing 24 are welded and connected, and the welding surface of the first housing 23 and / or the second housing 24 is a stepped - surface structure 26.

[0071] The stepped - surface structure 26 can, on the one hand, facilitate the installation and positioning of the first housing 23 and the second housing 24, and on the other hand, increase the contact area between the first housing 23 and the second housing 24 during welding, and improve the welding strength.

[0072] There is no specific limitation on the application of the electrolysis disinfection module 2 in the above - mentioned embodiment. On the basis of the above - mentioned embodiment, as a further - defined embodiment, as Figure 1 、 Figure 2As shown in the figure, the electrolytic disinfection module 2 is provided on the dishwasher, and the dishwasher includes: an inner tank 1; the electrolytic disinfection module 2 according to any of the above solutions, which is arranged upstream of the inner tank 1. The electrolytic disinfection module 2 includes an electrolytic chamber 25; a pipeline assembly that at least communicates the inner tank 1 with the electrolytic disinfection module 2. A pipeline water inlet 4 is provided on the pipeline assembly, and the electrolytic disinfection module 2 is located downstream of the pipeline water inlet 4. A salt feeding mechanism is adapted to supply chloride ions to the electrolytic chamber 25. An electrolyte solution is injected into the pipeline assembly through the pipeline water inlet 4. After the electrolyte solution enters the electrolytic disinfection module 2, disinfected water is prepared by electrolysis. The disinfected water enters the inner tank 1 to disinfect the tableware in the inner tank 1. Thus, the tableware can be disinfected in the dishwasher. At the same time, the disinfected water will disinfect the internal structures of the dishwasher such as the pipeline assembly, the inner tank 1, and the electrolytic disinfection module 2 when passing through the pipeline. Therefore, even after the disinfection treatment, although there is residual disinfected water in the internal structure of the dishwasher, bacteria will not grow and it is not easy to produce peculiar smell. Among them, salt can also be fed into the pipeline assembly upstream of the electrolytic chamber 25 or other components through which the water flows by the salt feeding mechanism. Water is injected into the pipeline assembly through the pipeline water inlet 4. The water contacts the salt before entering the electrolytic disinfection module 2 to fully dissolve the salt to form an electrolyte solution. The electrolyte solution further flows into the electrolytic disinfection module 2 and disinfected water is prepared by electrolysis.

[0073] On the basis of the above embodiments, as a further limited embodiment, as Figure 1 shown, it further includes: a breather 5, which is arranged on the back surface 11 of the inner tank 1, and the breather 5 is arranged upstream of the electrolytic disinfection module 2. As an alternative embodiment, the breather 5 is arranged at the bottom of the inner tank 1. As another alternative embodiment, the breather 5 is arranged on the side surface of the inner tank 1.

[0074] In this embodiment, an opening is provided on the inner tank 1, a door body is provided on the opening, and the surface of the inner tank 1 corresponding to the opening is the back surface 11. The surface below the opening is the bottom surface.

[0075] On the basis of the above embodiments, as a further limited embodiment, as Figure 1 、 Figure 2 shown, when the breather 5 is arranged on the back surface 11 of the inner tank 1, it is arranged close to the edge of the back surface 11 of the inner tank 1.

[0076] On the basis of the above embodiments, as a further limited embodiment, as Figure 1 shown, a flow meter 51 is provided on the breather 5. The flow meter 51 can count the amount of water flowing through, so as to facilitate the statistical calculation of the amount of water and the amount of disinfected water. As an alternative embodiment, the flow meter 51 is arranged on the pipeline assembly, upstream of the inner tank 1.

[0077] Based on the above embodiments, as a further limited embodiment, as Figure 1 shown, the water inlet of the respirator 5 is connected to the pipe water inlet 4 through a first pipe, and the water outlet of the respirator 5 is connected to the electrolytic disinfection module 2 through a second pipe.

[0078] Based on the above embodiments, as a further limited embodiment, as Figure 1 shown, a water cup 12 is provided at the bottom of the inner tank 1. The water cup 12 is communicated with the inner tank 1, and the water cup 12 is connected to the electrolytic disinfection module 2 through a third pipe. The water cup 12 can deliver the disinfected water into the inner tank 1 for disinfection use. In one embodiment, the water cup 12 is communicated with the spray arm assembly or the spraying mechanism in the inner tank 1, and the tableware inside the inner tank 1 is disinfected through the spray arm assembly or the spraying mechanism. As an alternative embodiment, as Figure 1 shown, a bottom cover 13 is provided at the bottom of the inner tank 1. A disinfection chamber is formed between the bottom cover 13 and the bottom of the inner tank 1, and the disinfection chamber is arranged downstream of the water cup 12. The disinfection chamber can be an additional disinfection space independent of the inner tank 1. After the tableware is washed, it is transferred into the disinfection chamber, and thus disinfection treatment is carried out in the disinfection chamber.

[0079] Based on the above embodiments, as a further limited embodiment, as Figure 1 shown, a first valve body 21 and a second valve body 22 are provided on the pipe assembly. The first valve body 21 is arranged on the second pipe, and the second valve body 22 is arranged on the third pipe.

[0080] When the first valve body 21 is opened and the second valve body 22 is closed, the electrolyte solution or water enters the electrolytic chamber 25 through the electrolytic water inlet 242 and accumulates in the electrolytic chamber 25. When the first valve body 21 and the second valve body 22 are both closed, the electrolytic disinfection module 2 is separated from the pipe assembly, and the electrolyte solution is sealed in the electrolytic chamber 25 for sufficient electrolysis to prepare the disinfected water. When the first valve body 21 is closed and the second valve body 22 is opened, the prepared disinfected water flows into the inner tank 1.

[0081] Based on the above embodiments, as a further limited embodiment, as Figure 1 shown, the third pipe is arranged at the bottom of the inner tank 1, and the electrolytic disinfection module 2 and the water cup 12 are respectively arranged on both sides of the third pipe. The electrolytic disinfection module 2 is arranged at the bottom of the inner tank 1. Through the separation function of the third pipe, a space for placing the electrolytic disinfection module 2 is formed at the bottom of the inner tank 1. Among them, as Figure 1As shown, the bottom cover 13 and the electrolytic disinfection module 2 are located between the second pipeline and the third pipeline. The bottom cover 13 bulges relative to the bottom of the inner container 1, forming a disinfection chamber with the inner container 1. The raised disinfection chamber is at the bottom of the inner container 1, and together with the second pipeline and the third pipeline, it encloses a space for placing and installing the electrolytic disinfection module 2, facilitating the assembly of workpieces, achieving rapid positioning and installation, and improving the assembly efficiency.

[0082] There is no specific limitation on the installation position of the electrolytic disinfection module 2. On the basis of the above-mentioned embodiments, as a further limited embodiment, as Figure 1 shown, the electrolytic disinfection module 2 is arranged below the inner container 1. The salt feeding mechanism includes: a salt feeding pipe 3, and the salt feeding port of the salt feeding pipe 3 extends outside the housing of the dishwasher. The salt feeding pipe 3 can extend the salt feeding port to the outside of the dishwasher, so as to facilitate the user to feed salt into the dishwasher from the outside of the dishwasher, such as Figure 1 、 Figure 2 shown, above the dishwasher, to dissolve and form an electrolyte solution inside the dishwasher, and electrolyze it in the electrolytic chamber 25 to prepare disinfected water. As an alternative embodiment, the electrolytic disinfection module 2 is arranged above the inner container 1 or on the side wall of the inner container 1. As another alternative embodiment, the salt feeding port extends to the outside of the dishwasher and is located on the side of the dishwasher.

[0083] In this embodiment, the working principle of the dishwasher itself is as follows:

[0084] Cathode: 2Cl--2e=Cl2

[0085] Anode: 2H2O + 2e-=H2 + 2OH-

[0086] Total reaction: 2Cl- + 2H2O=H2 + Cl2 + 2OH-

[0087] A disproportionation reaction will occur between chlorine gas and water: Cl2 + H2O=HCl + HClO. The generated HClO has certain oxidizing properties itself, thereby achieving the killing effect on bacteria and viruses.

[0088] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the embodiments. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the embodiments here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
