[0001] The present invention relates to the technical field of cleaning equipment, and particularly to a dishwasher. Background Art

[0002] With the improvement of living standards, dishwashers have gradually entered ordinary families, liberating hands and improving the quality of life. Generally, the main core components of existing dishwashers include: an inner container assembly, a water cup assembly, a spray arm assembly, a filter assembly, a washing pump, a drainage pump, pipelines, etc. Currently, dishwashers on the market generally perform main cleaning and tableware disinfection through high temperature (about 70°C).

[0003] Some existing dishwashers adopt UVC ultraviolet lamp disinfection, add silver ions to inhibit bacteria in the part materials, steam high-temperature disinfection, hot air drying and other disinfection methods. The above disinfection methods mainly act on the surface disinfection of tableware, and the effect on the interior of invisible parts is not good.

[0004] Some existing dishwashers also use ozone water for disinfection. Since the solubility of ozone in water is low, the sterilization effect is not very ideal, and most of the overflowed ozone is harmful to the human body. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect of poor disinfection effect of dishwashers in the prior art, so as to provide a dishwasher with good disinfection effect.

[0006] To solve the above problems, the present invention provides a dishwasher, including: a washing component, a disinfected water generating device, a power supply device and a cooling module.

[0011] The washing component is connected to the cooling medium outlet of the box body.

[0012] Further, the box body is of a flat structure, and the power supply device is fixedly arranged on the box body.

[0013] Further, a serpentine waterway is arranged in the box body, and the cooling medium inlet and the cooling medium outlet are located at both ends of the serpentine waterway.

[0014] Further, a heat conducting plate is provided between the power supply device and the cooling module.

[0015] Further, the distance between the end of the air inlet channel and the box body of the water storage structure is less than the distance between the end of the discharge electrode and the water storage structure.

[0016] Further, the water storage structure includes a lower cover and an upper cover hermetically connected to the lower cover. The discharge electrode and the loop electrode are both fixedly arranged on the upper cover, and the fluid discharge part is arranged on the upper cover.

[0017] Further, the air inlet channel includes a first insulating tube arranged to surround the discharge electrode outside, and the first insulating tube is fixed on the upper cover.

[0018] Further, the disinfection water generating device includes an electrode fixing frame fixed on the upper cover. The discharge electrode is fixed on the electrode fixing frame.

The electrode fixing frame is provided with a gas guiding channel communicating with the inside of the first insulating tube, and the gas guiding channel and the first insulating tube together form the air inlet channel.

[0019] Further, the electrode fixing frame is provided with a fixing hole for fixing the discharge electrode. The gas guiding channel includes a gas guiding cavity surrounding the fixing hole and an air inlet arranged on the electrode fixing frame and communicating with the gas guiding cavity.

[0020] Further, a first sealing member is provided between the upper surface of the upper cover and the electrode fixing frame. The first sealing member includes an annular body part, and the inner side of the body part has a first groove. The first insulating tube includes a vertical cylindrical part and a first bent edge arranged at the top of the vertical cylindrical part and extending radially outward.

The disinfection effect of the disinfectant water is superior to traditional disinfection methods such as high-temperature disinfection, steam disinfection, ultraviolet disinfection, and silver ion disinfection; when disinfection work needs to be carried out, the switch element is turned on to make the disinfectant water generated in the water storage structure flow into the water cup, be mixed and diluted with the water in the water cup, and the washing pump pumps the disinfectant water in the water cup into the spray arm. The spray arm sprays the disinfectant water onto the inner tank and the tableware in the inner tank to disinfect the tableware. The disinfectant water flows through the water cup, the washing pump, the spray arm, and the inner tank, and can disinfect them all-round, with a good disinfection effect. Moreover, the disinfectant water discharged by the machine not only does not pollute the environment, but also purifies the sewage.

[0026] The dishwasher of the present invention further includes a cooling module connected to the power supply device. When the power supply device generates heat during use, the cooling module can cool it and avoid accelerating the aging of the power supply device due to heat.

[0054] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0055] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance

[0056] In the description of the present invention, it should be noted that, unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0058] As Figure 19 、 Figure 20 、 Figure 1 and Figure 2 shown, this embodiment relates to a dishwasher, including a washing component, a disinfection water generating device a, a power supply device b, and a cooling module c. The cooling module c is connected to the power supply device b and is adapted to cool the power supply device b.

[0059] The disinfection water generating device a includes a water storage structure a1, a discharge electrode a2, a loop electrode a3, and a barrier medium. The water storage structure a1 has a water inlet a11 and a water outlet a12. The water inlet a11 is adapted to communicate with a water source. The water outlet a12 is connected to the washing component. The discharge electrode a2 is disposed inside the water storage structure a1 and is connected to the live wire b1 of the power supply device b. The loop electrode a3 is connected to the neutral wire b2 of the power supply device b. The barrier medium is disposed between the discharge electrode a2 and the loop electrode a3. An air inlet channel is provided on the water storage structure a1. The air inlet channel is adapted to introduce air, and the air inlet channel surrounds the outside of the discharge electrode a2. The power supply device b can provide high-voltage electricity for the discharge electrode a2, and it can be a high-frequency high-voltage device or other devices capable of providing high-voltage electricity.

[0060] As can be seen from the above technical solution, for the dishwasher in this embodiment, when disinfectant water needs to be prepared, tap water enters the water storage structure a1, and the power supply device b provides a high-frequency alternating voltage of about 6 - 15 KV to the discharge electrode a2. Air enters the water storage structure a1 through the air inlet channel. The discharge electrode a2 of the disinfectant water generating device a undergoes a glow discharge phenomenon, generating plasma in the liquid phase environment by means of high-voltage discharge. During discharge, high-energy electrons react violently with air and water molecules around the gas / liquid interface, generating plasma such as single oxygen atoms, ozonide ion groups, hydrogen peroxide ion groups, hydroxyl groups, nitrosyl groups, etc. with strong oxidizing ability and extremely strong killing ability for bacteria and viruses, producing plasma disinfectant water with the ability to kill bacteria and viruses. The disinfection effect of the disinfectant water is better than traditional disinfection methods such as high-temperature disinfection, steam disinfection, ultraviolet disinfection, and silver ion disinfection; when disinfection work needs to be carried out, the switch element is turned on to make the disinfectant water generated in the water storage structure a1 flow into the water cup 3 of the dishwasher and mix and dilute with the water in the water cup 3. The washing pump 14 pumps the disinfectant water in the water cup 3 into the spray arm, and the spray arm sprays the disinfectant water onto the inner tank 1 and the tableware in the inner tank 1 to disinfect the tableware. The disinfectant water flows through the water cup 3, the washing pump 14, the spray arm, and the inner tank 1 (the inner tank 1 is shown in Figure 21 ), and can disinfect it comprehensively with good disinfection effect. Moreover, the disinfectant water discharged by the machine not only does not pollute the environment, but also purifies the sewage.

[0061] On the basis of the above implementation manner, in a preferred implementation manner, the water storage structure a1 is provided with a fluid discharge part a5 to connect the inside and outside of the water storage structure a1. The fluid discharge part a5 is used to discharge the gas in the water storage structure a1 to ensure the stable air pressure in the water storage structure a1, or when the water in the water storage structure a1 overflows, it is discharged through the fluid discharge part a5.

[0062] The loop electrode a3 can be arranged on the outside or inside of the box body of the water storage structure a1. When the loop electrode a3 is arranged on the outside of the box body, the box body itself is made of an insulating material to form a blocking medium. When the loop electrode a3 is arranged on the inside of the box body, a blocking medium made of an insulating material is provided between the loop electrode a3 and the discharge electrode a2. The blocking medium can specifically be an insulating sleeve a23 coated outside the loop electrode a3 or the discharge electrode a2.

[0063] In addition, the applicant found during the R & D process that during the use of the dishwasher, the power supply device b is prone to heat generation, which leads to accelerated aging of the power supply device b and even poses a safety hazard. Therefore, the dishwasher of this embodiment further includes a cooling module c connected to the power supply device b. When the power supply device b generates heat during use, the cooling module c can cool it and prevent accelerated aging of the power supply device b caused by heat. Therefore, the power supply device b of this embodiment can overcome the defects that the power supply device b is prone to heat generation during use, resulting in accelerated aging of the power supply device b and posing a safety hazard. It helps to ensure the stability of the voltage output by the power supply device b and extend the service life of the power supply device b.

[0064] The cooling module c is preferably but not limited to an air-cooling device or a liquid-cooling device. For example, as Figure 2 shown, in this embodiment, the cooling module c is a liquid-cooling device and includes a box body c1. The box body c1 has a cooling medium inlet c2 and a cooling medium outlet c3. The cooling medium inlet c2 of the box body c1 is used to receive the cooling medium. The surface of the box body c1 is in surface contact with the power supply device b and can cool the power supply device b. The cooling medium outlet c3 can discharge the cooled cooling medium after heat exchange. The cooling medium can be selected as water or other heat-conducting fluids, such as freon, ammonia, or tetrafluoroethane, etc.

[0065] The cooling medium inlet c2 of the box body c1 can be directly connected to a water source. Preferably, however, the dishwasher further includes a water inlet pipeline assembly, a water path switching structure, and a washing assembly. Among them, the first end of the water inlet pipeline assembly is connected to the water source. The water path switching structure is arranged between the second end of the water inlet pipeline assembly and the cooling module c and the disinfection water generating device a. It has a first state in which the water inlet pipeline assembly is connected to the cooling medium inlet c2 of the cooling module c and a second state in which the water inlet pipeline assembly is connected to the disinfection water generating device a. The washing assembly is connected to the cooling medium outlet c3 of the box body c1.

[0066] Therefore, when the dishwasher needs to disinfect tableware, the water path switching structure can first switch to the second state and connect the water inlet pipeline assembly to the disinfection water generating device a, so as to supply water to the disinfection water path generating device. When the amount of water in the disinfection water generating device a is sufficient, the water path switching structure can switch to the first state and connect the water inlet pipeline assembly to the cooling medium inlet c2 of the cooling module c. At this time, the power supply device b starts to supply power to the disinfection water generating device a, and the water inlet pipeline assembly can supply water to the cooling medium inlet c2 of the cooling module c, thereby cooling the power supply device b. The cooling medium outlet c3 of the box body c1 is connected to the washing assembly, which enables the cooling water to wash the tableware after cooling the power supply device b. Therefore, the dishwasher of this embodiment can cool the power supply device b by means of the washing water necessary for cleaning tableware, without consuming additional water or equipping a power source, improving the energy utilization rate.

[0067] When the dishwasher does not need to disinfect tableware, the water path switching structure can directly switch to the first state and connect the water inlet pipe assembly to the cooling medium inlet c2 of the cooling module c, and the water inlet pipe assembly can supply water to the cooling medium inlet c2 of the cooling module c. The cooling medium outlet c3 of the box body c1 is connected to the washing assembly, so that the cooling water can enter the washing assembly after passing through the cooling module c and wash the tableware.

[0068] On the basis of the above embodiment, in a preferred embodiment, the water path switching structure includes a three-way valve 13. The water inlet end of the three-way valve 13 is connected to the second end of the water inlet pipe assembly, the first water outlet end of the three-way valve 13 is connected to the first end of the flow meter 7, the water inlet a11 of the disinfected water generating device a is connected to the second end of the flow meter 7, and the second water outlet end of the three-way valve 13 is connected to the washing assembly. In this embodiment, when washing is required, the water inlet end and the second water outlet end of the three-way valve 13 are made to communicate. When disinfected water needs to be prepared, the water inlet end and the first water outlet end of the three-way valve 13 are made to communicate. The structure of the water path switching structure is simple and convenient to control. In an alternative embodiment, the water path switching structure includes a first switching valve and a second switching valve. The first end of the water inlet pipe assembly is connected to the first end of the flow meter 7, the second end of the water inlet pipe assembly is connected to the washing assembly, the first switching valve is arranged between the water inlet pipe assembly and the flow meter 7, and the second switching valve is arranged between the water inlet pipe assembly and the washing assembly.

[0069] In the present embodiment, the box body c1 can be arranged to be in surface contact with any side surface of the power supply device b. However, in order to improve the space utilization rate inside the dishwasher and the installation stability of the power supply device b, the box body c1 is preferably arranged in a flat structure. The power supply device b is fixedly arranged on the box body c1. In order to extend the residence time of the cooling water in the box body c1 and thus improve the heat exchange efficiency between the cooling water and the power supply device b, the box body c1 is preferably provided with a meandering water path, such as a serpentine water path c4. As Figure 4 shown, when the water path in the box body c1 is selected as the serpentine water path, the cooling medium inlet c2 and the cooling medium outlet c3 are preferably located at both ends of the serpentine water path c4. In order to further increase the heat exchange efficiency between the cooling module c and the power supply device b, a heat conducting plate c5 is also provided between the power supply device b and the box body c1. As Figure 3 shown, the heat conducting plate c5 is preferably but not limited to being made of heat conducting materials such as steel, aluminum, and silica gel. In order to further increase its heat conduction efficiency, a flow channel and a heat conducting medium that can flow in the flow channel, such as mineral oil or ethylene glycol, etc., can also be provided in the heat conducting plate c5, which is well known to those skilled in the art and will not be elaborated here.

[0070] In this embodiment, in order to firmly fix the power supply device b on the box body c1, a connection component is preferably further provided between the power supply device b and the heat conducting plate c5. The connection component can be selected from a clamping component, a riveting component, a threaded connection component, etc. Preferably, however, power supply device ear plates are provided at both ends of the power supply device b. Heat conducting plate connection holes are provided at positions corresponding to the connection ear plates of the heat conducting plate c5, and the power supply device connection ear plates and the heat conducting plate connection holes can cooperate with each other to fixedly connect the power supply device b and the heat conducting plate c5.

[0071] On the basis of the above-mentioned implementation manner, the distance between the end of the air intake passage and the water storage structure a1 is preferably less than the distance between the end of the discharge electrode a2 and the water storage structure a1. It should be noted that the end of the air intake passage is the end of the air intake passage located inside the box body. Combining Figure 5 , the end of the air intake passage is its lower end, and the end of the discharge electrode a2 also refers to its lower end. In this implementation manner, it can be ensured that a gas-liquid interface is formed on the lower side of the end of the discharge electrode a2, so that when the discharge electrode a2 discharges, high-energy electrons react violently with air and water molecules around the gas / liquid interface to generate plasma.

[0072] On the basis of the above-mentioned implementation manner, in a preferred implementation manner, as Figure 5 shown, the water storage structure a1 includes a lower cover a13 and an upper cover a14 that is hermetically connected to the lower cover a13. The discharge electrode a2 and the loop electrode a3 are both fixedly arranged on the upper cover a14. In this implementation manner, since the discharge electrode a2 and the loop electrode a3 are both integrally installed on the upper cover a14, the structure is simple and compact. During assembly, after the discharge electrode a2 and the loop electrode a3 are both installed on the upper cover a14, the upper cover a14 and the lower cover a13 are assembled together by sol welding, which is convenient for improving the assembly efficiency. In an alternative implementation manner, the discharge electrode a2 is arranged on the upper cover a14, the loop electrode a3 is arranged in a sheet shape on the bottom wall or side wall of the water storage structure a1, and the connection end of the loop electrode a3 connected to the zero line b2 of the power supply device b is exposed outside the water storage structure a1.

[0073] As Figure 5 and 6 shown, a fluid discharge part a5 is provided on the upper cover a14. The setting of the fluid discharge part a5 can timely discharge the gas generated inside the water storage structure a1 to ensure the air pressure balance inside the water storage structure a1. At the same time, when the water level in the water storage structure a1 reaches the fluid discharge part a5, it overflows through the fluid discharge part a5, which can ensure the pressure balance inside the water storage structure a1.

[0074] On the basis of the above-mentioned implementation manner, in a preferred implementation manner, as Figure 5 , Figure 15 and Figure 16As shown in the figure, the intake channel includes a first insulating tube a6 disposed around the outside of the discharge electrode a2. The first insulating tube a6 is fixed to the upper cover a14. In this embodiment, the first insulating tube a6, the discharge electrode a2, and the loop electrode a3 are all integrally mounted on the upper cover a14, which can further improve the assembly efficiency.

[0075] The first insulating tube a6 may specifically be a glass tube or a ceramic tube.

[0076] Based on the above embodiment, in a preferred embodiment, as Figure 7 shown, the disinfection water generating device a includes an electrode fixing bracket a7 fixed to the upper cover a14. The discharge electrode a2 is fixed to the electrode fixing bracket a7. The upper end of the first insulating tube a6 is hermetically connected to the electrode fixing bracket a7. The electrode fixing bracket a7 is provided with a gas guiding channel that communicates with the inside of the first insulating tube a6. The gas guiding channel and the first insulating tube a6 together form the intake channel. In this embodiment, the electrode fixing bracket a7 is used to fix both the discharge electrode a2 and the first insulating tube a6, which can further improve the assembly efficiency, and the structure of the intake channel is relatively simple and does not require additional space. In other alternative embodiments, the electrode fixing bracket a7 is only used to fix the discharge electrode a2. The intake channel includes a first intake section surrounding the outside of the lower half of the discharge electrode a2 and a second intake section connected to the upper end of the first intake section. The second intake section is fixedly arranged on the upper cover a14 or the side wall of the water storage structure a1, and the second intake section is inclined.

[0077] Based on the above embodiment, in a preferred embodiment, the electrode fixing bracket a7 is provided with a fixing hole a71 for fixing the discharge electrode a2. The gas guiding channel includes a gas guiding cavity a72 surrounding the outside of the fixing hole a71 and an air inlet a73 provided on the electrode fixing bracket a7 and communicating with the gas guiding cavity a72. The air inlet a73 communicates with the gas guiding cavity a72. The upper end of the first insulating tube a6 is hermetically connected to the electrode fixing bracket a7. The gas guiding cavity a72 communicates with the inside of the first insulating tube a6. The air inlet a73, the gas guiding cavity a72, and the first insulating tube a6 together form the intake channel. In this embodiment, air enters the first insulating tube a6 through the air inlet a73 and the gas guiding cavity a72. The electrode fixing bracket a7 is used to fix both the discharge electrode a2 and the first insulating tube a6, with a simple and compact structure. Moreover, since the gas guiding cavity a72 surrounds the outside of the fixing hole a71, it can ensure that the air is evenly located outside the discharge electrode a2.

[0078] Specifically, in combination with Figure 10 、 Figure 11 and Figure 12 , the electrode fixing bracket a7 is provided with screw holes, and the electrode fixing bracket a7 is connected to the upper cover a14 by screws.

[0079] On the basis of the above - mentioned embodiments, in a preferred embodiment, in combination with Figure 13 and Figure 14 , a first seal a8 is provided between the upper surface of the upper cover a14 and the electrode fixing bracket a7. The first seal a8 includes an annular body portion a81, and the inner side of the body portion a81 has a first groove a82. The first insulating tube a6 includes a vertical cylindrical portion a61 and a first bending edge a62 provided at the top of the vertical cylindrical portion a61 and extending radially outward. The first bending edge a62 is embedded in the first groove a82. In this embodiment, as shown in Figure 15 and Figure 16 , the first bending edge a62 at the upper end of the first insulating tube a6 is embedded in the first groove a82 of the first seal a8. After installation, the electrode fixing bracket a7 presses on the upper end of the first seal a8, realizing the sealed connection between the first insulating tube a6 and the motor fixing bracket. The sealing performance is good, and the first seal a8 can play a buffering and protecting role for the first insulating tube a6, preventing the first insulating tube a6 from being damaged by collision.

[0080] In one embodiment, as shown in Figure 18 , the loop electrode a3 and the upper cover a14 are sealed and connected through a second seal a109, and the second seal a109 is an O - ring.

[0081] On the basis of the above - mentioned embodiments, in a preferred embodiment, as shown in Figure 8 , Figure 9 , Figure 10 and Figure 11 , a second groove a711 is provided in the fixing hole a71, and the discharge electrode a2 has a second bending edge a21 adapted to be embedded in the second groove a711. In this embodiment, by embedding the second bending edge a21 of the discharge electrode a2 into the second groove a711 in the fixing hole a71, the discharge electrode a2 can be prevented from detaching from the electrode fixing bracket a7. Among them, the shape of the second groove a711 is preferably annular, and correspondingly, the second bending edge a21 is also annular.
