[0104] Example 1

[0105] This embodiment provides a dishwasher.

[0106] In one embodiment, Figures 1 to 17 As shown, a dishwasher includes a washing assembly and a disinfectant water generating device a. The disinfectant water generating device a includes a water storage structure a1, a discharge electrode a2, a return electrode a3, a barrier medium, and an air inlet channel. 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, and the water outlet a12 is connected to the washing assembly. The water storage structure a1 is provided with a switch element for controlling the water flow from the water outlet a12. The discharge electrode a2 is disposed within the water storage structure a1 and is connected to the live wire b1 of a power supply device b, which is capable of providing a high voltage of 6 kV to 15 kV to the discharge electrode a2. The return electrode a3 is connected to the neutral wire b2 of the power supply device b. The barrier medium is disposed between the return electrode a3 and the discharge electrode a2. The air inlet channel is disposed on the water storage structure a1 and is adapted to admit air. The air inlet channel surrounds the discharge electrode a2.

[0107] In this embodiment, when the disinfectant water generating device a is operating, the power supply device b provides a high-frequency alternating voltage of 6kV-15kV to the discharge electrode a2, and air enters the water storage structure a1 through the air inlet channel. The discharge electrode a2 of the disinfectant water generating device a generates a glow discharge phenomenon, and a plasma is generated in the liquid phase environment by high-voltage discharge. During the discharge, high-energy electrons react violently with air and water molecules around the gas / liquid interface to generate a plasma containing highly oxidizing single oxygen atoms, ozone ion groups, hydrogen peroxide ion groups, hydroxyl groups, nitroso groups, etc., which have a strong killing ability against bacteria and viruses. This produces plasma disinfectant water with bacterial and viral disinfecting ability. 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 is required, the switch element is opened, allowing the disinfectant water generated in the water storage structure a1 to flow into the washing component, where it is diluted with the water in the washing component. The disinfectant liquid is sprayed onto the tableware through the washing component for disinfection. The disinfectant water flows through the washing component, which can disinfect the washing component and the washing component's pipelines, achieving all-round disinfection with good disinfection effect. Moreover, the disinfectant water discharged from the dishwasher not only does not pollute the environment, but also purifies the sewage.

[0108] The power supply device b can be a high-frequency, high-voltage device or another device capable of providing high-voltage electricity. For example, the power supply device b includes a 220V power supply and a transformer connected to the power supply. The discharge electrode a2 is connected to the live wire of the transformer, and the return electrode a3 is connected to the neutral wire of the transformer. The return electrode a3 can be located outside or inside the water storage structure's housing. When the return electrode a3 is located outside the housing, the housing itself is made of an insulating material to form a barrier. When the return electrode a3 is located inside the housing, a barrier made of an insulating material is provided between the return electrode a3 and the discharge electrode a2. The barrier can specifically be an insulating sleeve covering the return electrode a3 or the discharge electrode a2.

[0109] Specifically, the air pump 5 provides air to the air inlet passage.

[0110] In one embodiment, a washing assembly includes a cup, a washing pump, a spray arm, and an inner container. During washing, water enters the cup, the washing pump pumps the water from the cup into the spray arm, and the spray arm sprays the water into the inner container, spraying and cleaning the dishes inside. The water in the inner container then flows into the cup, performing a cyclic washing cycle. After washing is complete, the water in the inner container is discharged into the sewer. A switch element can control the disinfectant water generated in the water storage structure a1 to flow into the cup or the inner container. In an alternative embodiment, the washing assembly includes an inner container and an ultrasonic generator disposed therein. During washing, water enters the inner container, the ultrasonic generator cleans the dishes inside, and a switch element can control the disinfectant water generated in the water storage structure a1 to flow into the inner container. Therefore, the water outlet a12 of the disinfectant water generating device a can be connected to the cup or the inner container, allowing the disinfectant water to flow into either the cup or the inner container.

[0111] On the basis of the above embodiment, in a preferred embodiment, the distance between the end of the air inlet channel and the box of the water storage structure a1 is smaller than the distance between the end of the discharge electrode a2 and the box. It should be noted that the end of the air inlet channel is the end of the air inlet channel located in the box. Figure 2 The end of the air inlet channel is its lower end, and the end of the discharge electrode a2 also refers to its lower end. In this embodiment, a gas-liquid interface is formed on the lower side of the end of the discharge electrode a2. When the discharge electrode a2 discharges, high-energy electrons around the gas / liquid interface react violently with air and water molecules to generate plasma.

[0112] On the basis of the above embodiment, in a preferred embodiment, a fluid discharge portion a5 is provided on the water storage structure a1 to connect the inner and outer sides of the water storage structure a1. The fluid discharge portion a5 is used to discharge the gas in the water storage structure a1 to ensure the stability of the 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 portion a5.

[0113] On the basis of the above embodiment, in a preferred embodiment, the water storage structure a1 includes a lower cover a13 and an upper cover a14 sealed with the lower cover a13, and the discharge electrode a2 and the return electrode a3 are fixedly arranged on the upper cover a14. In this embodiment, since the discharge electrode a2 and the return electrode a3 are both integrated and installed on the upper cover a14, the structure is simple and compact. During assembly, after the discharge electrode a2 and the return 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 facilitates improving assembly efficiency. In an alternative embodiment, the discharge electrode a2 is arranged on the upper cover a14, and the return electrode a3 is arranged in sheet form on the bottom wall or side wall of the water storage structure a1, such as Figure 16 and Figure 17As shown, the connection end of the loop electrode a3 connected to the neutral line b2 of the power supply device b is exposed outside the water storage structure a1. Figure 16 and Figure 17 Two loop electrodes a3 are provided in the figure, but only one of them is required in practice.

[0114] Based on the above embodiment, in a preferred embodiment, the air inlet passage includes a first insulating tube a6 surrounding 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 return electrode a3 are all integrally mounted on the upper cover a14, further improving assembly efficiency.

[0115] The first insulating tube a6 can specifically be a glass tube or a ceramic tube.

[0116] Based on the above embodiment, in a preferred embodiment, the disinfectant water generating device includes an electrode holder a7 fixed to the upper cover a14. The discharge electrode a2 is fixed to the electrode holder a7. The upper end of the first insulating tube a6 is sealed to the electrode holder a7. The electrode holder a7 is provided with an air channel that communicates with the interior of the first insulating tube a6. The air channel and the first insulating tube a6 together form an air inlet channel. In this embodiment, the electrode holder a7 serves to secure both the discharge electrode a2 and the first insulating tube a6, further improving assembly efficiency. The air inlet channel is also relatively simple and does not require additional space. In other alternative embodiments, the electrode holder a7 serves only to secure the discharge electrode a2. The air inlet channel includes a first air inlet section surrounding the outer side of the lower half of the discharge electrode a2 and a second air inlet section connected to the upper end of the first air inlet section. The second air inlet section is fixed to the upper cover a14 or to the sidewall of the water storage structure a1 and is inclined.

[0117] Based on the above embodiment, in a preferred embodiment, the electrode holder a7 is provided with a fixing hole a71 for securing the discharge electrode a2. The air flow path includes an air flow cavity a72 surrounding the fixing hole a71 and an air inlet a73 provided on the electrode holder a7 and connected to the air flow cavity. The air inlet a73 communicates with the air flow cavity a72. The upper end of the first insulating tube a6 is sealed to the electrode holder a7. The air flow cavity a72 communicates with the interior of the first insulating tube a6. The air inlet a73, air flow cavity a72, and the first insulating tube a6 collectively form the air flow path. In this embodiment, air enters the first insulating tube a6 through the air inlet a73 and air flow cavity a72. The electrode holder a7 serves to secure both the discharge electrode a2 and the first insulating tube a6, resulting in a simple and compact structure. Furthermore, since the air flow cavity a72 surrounds the fixing hole a71, it ensures that air is evenly distributed outside the discharge electrode a2.

[0118] Specifically, the electrode fixing frame a7 is provided with screw holes, and the electrode fixing frame a7 is connected to the upper cover a14 by screws.

[0119] Based on the above embodiment, in a preferred embodiment, a first seal a8 is disposed between the upper surface of the upper cover a14 and the electrode holder a7. The first seal a8 comprises an annular main body a81 with a first annular groove a82 defined within the inner side of the main body a81. The first insulating tube a6 comprises a vertical cylindrical portion a61 and a first flange a62 extending radially outward from the top of the vertical cylindrical portion a61. The first flange a62 is embedded in the first annular groove a82. In this embodiment, the first flange a62 at the upper end of the first insulating tube a6 is embedded in the first annular groove a82 of the first seal a8. After installation, the electrode holder a7 is pressed against the upper end of the first seal a8, achieving a sealed connection between the first insulating tube a6 and the electrode holder. This provides excellent sealing performance, and the first seal a8 provides a buffering and protective effect on the first insulating tube a6, preventing damage to the first insulating tube a6 from collisions.

[0120] In one embodiment, Figure 2 and Figure 15 As shown, the loop electrode a3 and the upper cover a14 are sealed and connected via a second sealing member a109, which is a sealing ring.

[0121] In a preferred embodiment, based on the above embodiment, the first sealing member a8 further comprises a plurality of annular sealing ribs a83 disposed at the upper and / or lower ends of the main body a81. In this embodiment, the sealing ribs a83 further serve a sealing function. Specifically, the sealing ribs a83 may be disposed only at the upper end of the main body a81, only at the lower end of the main body a81, or both.

[0122] In a preferred embodiment, based on the above embodiment, a second annular groove a711 is provided within the fixing hole a71, and the discharge electrode a2 has a second flange a21 adapted to fit within the second annular groove a711. In this embodiment, the second flange a21 of the discharge electrode a2 fits within the second annular groove a711 within the fixing hole a71, thereby preventing the discharge electrode a2 from detaching from the electrode holder a7.

[0123] Based on the above embodiment, in a preferred embodiment, the return electrode a3 is provided with a third flange a31, which is fixedly connected to the upper cover a14. In this embodiment, the provision of the third flange a31 facilitates securing the return electrode a3 to the upper cover a14. Specifically, the third flange a31 and the upper cover a14 are connected by screws or welding.

[0124] On the basis of the above embodiment, in a preferred embodiment, as Figure 1 and Figure 3 As shown, the upper cover a14 has an upper cover groove a141 that is recessed toward the lower cover a13, and the electrode holder a7 is disposed within the upper cover groove a141. In this embodiment, by locating the electrode holder a7 within the mounting slot, collision and interference between the electrode holder a7 and other structures can be avoided. This also reduces the overall height of the disinfectant water generator a and the installation space occupied by the disinfectant water generator a.

[0125] Among them, Figure 8 and Figure 9 As shown, the discharge electrode a2 in the above embodiments includes a discharge electrode body a22 and an insulating sleeve a23 arranged on the outside of the discharge electrode body a22, the second flange edge a21 is arranged on the insulating sleeve a23, and the lower end of the discharge electrode body a22 is arranged to be needle-tip-shaped to facilitate the generation of an arc.

[0126] Example 2

[0127] This embodiment provides a dishwasher.

[0128] In one embodiment, Figures 18 to 20 As shown, the dishwasher includes a water inlet piping assembly, a washing assembly, a disinfectant water generator a, and a water circuit switching mechanism. The first end of the water inlet piping assembly is connected to a water source and includes a water inlet solenoid valve 9. The washing assembly is connected to the second end of the water inlet piping assembly. The water inlet a11 of the disinfectant water generator a is connected to the second end of the water inlet piping assembly, and the water outlet a12 of the disinfectant water generator a is connected to the washing assembly. The specific structure of the disinfectant water generator a is the same as that in Example 1 and will not be described in detail in this embodiment.

[0129] When the dishwasher does not need to prepare disinfectant water and only the washing component is washed with water, the water path switching structure switches to the first state, tap water enters through the first end of the water inlet pipe assembly, and enters the washing component through the second end of the water inlet pipe assembly for washing; when the dishwasher needs to prepare disinfectant water, the water path switching structure switches to the second state, tap water enters through the first end of the water inlet pipe assembly, and enters the water storage structure a1 through the second end of the water inlet pipe assembly, the power supply device b provides a high-frequency alternating voltage of 6KV-15KV to the discharge electrode a2, and the air enters the water storage structure a1 through the air inlet channel. The discharge electrode a2 of the disinfectant water generating device a generates a glow discharge phenomenon, and uses high-voltage discharge to generate plasma in a liquid environment. During discharge, high energy is generated around the gas / liquid interface. Electrons react violently with air and water molecules, generating highly oxidizing plasma, including single oxygen atoms, ozone ions, hydrogen peroxide ions, hydroxyl groups, and nitroso groups. These atoms possess potent antibacterial and antiviral capabilities, producing plasma disinfectant water with superior bacterial and viral disinfecting capabilities. This disinfectant water is superior to traditional disinfection methods such as high-temperature disinfection, steam disinfection, ultraviolet disinfection, and silver ion disinfection. When disinfection is required, the switch element is opened, allowing the disinfectant water generated in the water storage structure a1 to flow into the washing assembly, where it is diluted with the water in the washing assembly. The disinfectant is then sprayed onto the tableware through the washing assembly, disinfecting the washing assembly and its piping, achieving comprehensive disinfection with excellent results. Furthermore, the disinfectant water discharged from the dishwasher not only does not pollute the environment but also purifies wastewater.

[0130] Based on the above embodiment, in a preferred embodiment, a flow meter 7 is provided between the disinfectant water generating device a and the second end of the water inlet pipe assembly. In this embodiment, the flow meter 7 is provided to control the amount of water entering the water storage structure a1, thereby controlling the amount of disinfectant water produced, and further controlling the proportional dilution of the disinfectant water with the water in the washing assembly. At the same time, the flow meter 7 prevents the amount of water entering the water storage structure a1 from being too little or too much, thereby ensuring the efficient production of disinfectant water.

[0131] Based on the above embodiment, in a preferred embodiment, the water circuit 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 pipeline assembly, the first water outlet end of the three-way valve 13 is connected to the first end of the flow meter 7 via a first pipeline g1, the water inlet a11 of the disinfectant water generating device a is connected to the second end of the flow meter 7 via a second pipeline g2, and the second water outlet end of the three-way valve 13 is connected to the washing assembly via a third pipeline g3. In this embodiment, when washing is required, the water inlet end of the three-way valve 13 is connected to the second water outlet end, and when disinfectant water is required, the water inlet end of the three-way valve 13 is connected to the first water outlet end. The water circuit switching structure has a simple structure and is easy to control. In an alternative embodiment, the water circuit switching structure includes a first switch valve and a second switch valve, which can connect one end of the first pipeline g1 to the second end of the water inlet pipeline assembly, the second end of the first pipeline g1 is connected to the first end of the flowmeter 7, one end of the third pipeline g3 is connected to the second end of the water inlet pipeline assembly, and the second end of the third pipeline g3 is connected to the washing assembly. The first switch valve is arranged on the first pipeline g1, and the second switch valve is arranged on the third pipeline g3.

[0132] Based on the above embodiment, in a preferred embodiment, the switching element is a water pump 4. The first end of the water pump 4 is connected to the water outlet a12 of the disinfectant water generator a via a fourth pipe g4, and the second end of the water pump 4 is connected to the washing assembly via a fifth pipe g5. In this embodiment, the disinfectant water generated by the disinfectant water generator a can be pumped into the washing assembly regardless of the installation location of the disinfectant water generator a. In an alternative embodiment, the switching element is a solenoid valve. In this embodiment, the installation location of the disinfectant water generator a should be higher than the bottom of the dishwasher's inner tank 1.

[0133] Based on the above embodiment, in a preferred embodiment, the water inlet pipeline assembly includes: a sixth pipeline g6, a respirator 8, and a water softener 6. One end of the sixth pipeline g6 is connected to a water source, and the other end of the sixth pipeline g6 is connected to the first end of a water inlet solenoid valve 9. The water inlet end of the respirator 8 is connected to the second end of the water inlet solenoid valve 9 via a seventh pipeline g7. The water outlet end of the respirator 8 is connected to the water inlet end of the water softener 6, and the water outlet end of the water softener 6 constitutes the second end of the water inlet pipeline assembly. In this embodiment, water from the water source enters the water inlet solenoid valve 9 through the sixth pipeline g6, then enters the respirator 8 through the seventh pipeline g7, and then enters the water softener 6. After being softened in the water softener 6, it enters the water circuit switching structure. This embodiment is capable of discharging water vapor in the inner tank 1 and buffering water when water is taken in by setting a respirator 8. The setting of the water softener 6 can soften the water before it enters the disinfection water generating device a and the washing component, and uses soft water for glow discharge to avoid scaling of the discharge electrode a2 and the loop electrode a3 in the disinfection water generating device a.

[0134] Specifically in one embodiment, the water outlet of the respirator 8 is sealedly connected to the water inlet of the water softener 6 , and the water outlet of the water softener 6 is connected to the water inlet of the three-way valve 13 through the eighth pipeline g8 .

[0135] In the dishwasher provided in this embodiment, when the dishwasher does not need to prepare disinfectant water and only needs to fill the washing chamber with water for washing, the three-way valve 13 is switched to the first state. Tap water flows through the faucet 16, the sixth pipe g6, the water inlet solenoid valve 9, the seventh pipe g7, the breather 8, the water softener 6, the eighth pipe g8, the three-way valve 13, and the third pipe g3 into the water cup 3. The washing pump 14 pumps the water in the water cup 3 into the spray arm 15. The spray arm 15 sprays the water into the inner tank 1, spraying and cleaning the tableware in the inner tank 1. The water in the inner tank 1 will flow into the water cup 3, and a circulating wash cycle will be performed. After washing is completed, the water is discharged into the sewer 17 through the drain pump 10, the first drain pipe g9, the U-shaped structure of the breather 8, and the second drain pipe g10. When the dishwasher needs to prepare disinfectant water, the water path switching mechanism switches to the second state. Tap water flows sequentially through the faucet 16, the sixth pipeline g6, the water inlet solenoid valve 9, the seventh pipeline g7, the respirator 8, the water softener 6, the eighth pipeline g8, the three-way valve 13, the first pipeline g1, the flowmeter 7, and the second pipeline g2 into the water storage structure a1 of the disinfectant water generating device a, where it is electrolyzed to generate disinfectant water. When disinfection is required, the water pump 4 is turned on, allowing the disinfectant water generated in the water storage structure a1 to flow sequentially through the fourth pipeline g4, the water pump 4, and the fifth pipeline g5 into the water cup 3, where it is mixed and diluted with the water in the water cup 3. The washing pump 14 pumps the disinfectant water from the water cup 3 into the spray arm 15, which sprays the disinfectant water onto the inner container 1 and the tableware inside the inner container 1, disinfecting the tableware. The disinfectant water flows through the water cup 3, the washing pump 14, the spray arm 15, and the inner container 1, achieving a comprehensive disinfection effect. After the disinfection is completed, the washing pump 14 is started to discharge the disinfection water and washing water, and then the hot air drying device is started to dry the tableware and the washing cavity. Finally, the dishwasher achieves the effect of washing, disinfecting and storing in one.

[0136] Example 3

[0137] This embodiment provides a dishwasher. In one embodiment, the dishwasher assembly differs from the aforementioned embodiment 1 in that the washing assembly includes an inner container 1, and a disinfectant water generator a is disposed on a side wall of the inner container. The specific structure of the disinfectant water generator a is the same as that of embodiment 1 and will not be described in detail in this embodiment.

[0138] The switching element can be a water outlet solenoid valve or a water pump. When disinfection is required, the solenoid valve or pump is opened, allowing the disinfectant generated in the water storage structure a1 to flow into the inner container 1, effectively disinfecting the tableware. By mounting the disinfectant generating device a on the side wall of the inner container 1, when the water outlet valve 12 is opened, the disinfectant generated in the water storage structure a1 automatically flows into the inner container 1 by gravity, eliminating the need for a separate pump and resulting in a relatively simple structure.

[0139] In one embodiment, a dishwasher comprises a base, side panels, and a top panel. The side panels are mounted on the base, and the top panel is mounted on the side panels, forming the housing of the dishwasher. An inner container 1 is positioned on the base, a water cup is positioned at the bottom of the inner container 1, and a spray arm is positioned within the inner container 1. A washing pump is mounted on the base, one end of the washing pump being connected to the water cup and the other end to the spray arm. Disinfectant water flows into the inner container 1 and then into the water cup, where it mixes and dilutes with water in the cup. The washing pump pumps the disinfectant water in the cup into the spray arm, which sprays the disinfectant water onto the inner container 1 and the tableware inside it, thereby disinfecting the tableware. The disinfectant water flows through the water cup, washing pump, spray arm, and inner container 1, providing a comprehensive disinfection.

[0140] Based on the above embodiment, in a preferred embodiment, the water storage structure a1 is provided on the outer wall of the inner liner 1. In this embodiment, the water storage structure a1 is provided on the outer wall of the inner liner 1. On the one hand, it is convenient to install and fix the water storage structure a1, and on the other hand, it does not occupy the space inside the inner liner 1.

[0141] Specifically in one embodiment, Figure 21 、 Figure 23 and Figure 24 As shown, a pair of connecting lugs are provided on the top of the water storage structure a1, each with a connection hole. The connecting lugs are connected to the side walls of the inner container 1 by screws. In an alternative embodiment, a slot can be machined into the outer wall of the inner container 1, and the water storage structure a1 is inserted into the slot. When the dishwasher is assembled, the water storage structure a1 is sandwiched between the inner container 1 and the outer side panels of the inner container 1, ensuring a secure connection of the water storage structure a1.

[0142] On the basis of the above embodiment, in a preferred embodiment, as Figure 22As shown, the water outlet a12 passes through the side wall of the inner liner 1. Specifically, a first mounting through hole is provided on the inner liner 1, and the water outlet a12 is provided in the first mounting through hole. In this embodiment, by making the water outlet a12 pass through the side wall of the inner liner 1, the setting of the connecting pipe between the water outlet a12 and the inner liner 1 is reduced. At the same time, the water outlet a12 is embedded in the first mounting through hole, which supports the water storage structure a1 and can further ensure that the water storage structure a1 is firmly connected. Of course, in other alternative embodiments, the water outlet a12 of the water storage structure a1 can be connected to the inner liner 1 through a connecting pipe, or the water outlet a12 of the water storage structure a1 can be connected to the water cup through a connecting pipe.

[0143] On the basis of the above embodiment, in a preferred embodiment, a side wall of the water storage structure a1 is recessed toward the inner side of the water storage structure a1 to form an installation groove a101, a first opening a102 is provided at the bottom of the installation groove a101, and a second opening a103 is provided on the lower side wall of the installation groove a101. The water outlet solenoid valve 12 includes a movable component sealed in the installation groove a101, and a plug 1201 is provided at the end of the movable component. The plug 1201 has a closed position for blocking the first opening a102 and an open position for connecting the first opening a102 with the second opening a103. A first partition a104 is provided in the water storage structure a1, and one end of the first partition a104 is connected to the bottom of the installation groove a101 and is located at the lower side of the first opening a102. The first partition a104 separates the water storage structure a1 into a first chamber and a second chamber. The first chamber is located above the second chamber, and a water outlet a12 is provided on the side wall of the second chamber. In this embodiment, when it is necessary to allow disinfectant water to flow into the inner tank 1, the movable component drives the plug 1201 to leave the first opening a102, and the water in the first chamber flows into the second chamber through the first opening a102 and the second opening a103, and flows into the inner tank 1 through the water outlet a12 on the second chamber; when the dishwasher is in the normal washing process or the process of preparing disinfectant water, the movable component drives the plug 1201 to move and seal the first opening a102. At this time, the disinfectant water in the first chamber cannot enter the second chamber, and cannot flow to the inner tank 1.

[0144] On the basis of the above embodiment, in a preferred embodiment, the water storage structure a1 includes a first wall panel a105 attached to the outer wall of the inner tank 1 and a second wall panel a106 opposite to and spaced from the first wall panel a105. The left side of the first wall panel a105 is connected to the left side of the second wall panel a106 by a third wall panel a107, and the right side of the first wall panel a105 is connected to the right side of the second wall panel a106 by a fourth wall panel a108. The mounting groove a101 can be provided on the third wall panel a107 or on the fourth wall panel a108. Figure 25As shown, the installation groove a101 is provided on the fourth wall panel a108, and the notch of the installation groove a101 is located on the right side of the water storage structure a1. The movable component can move in the left and right directions, and can make full use of the space between the inner liner 1 and the outer shell without increasing the gap between the inner liner 1 and the outer shell.

[0145] On the basis of the above embodiment, in a preferred embodiment, the moving assembly includes an electromagnet and an iron core 1202. In this embodiment, the electromagnet is sealed and installed outside the notch of the installation slot a101 through a third sealing member 1204. A spring 1203 is provided between the iron core 1202 and the electromagnet. When the electromagnet is not energized, the iron core 1202 drives the plug 1201 to block the first opening a102. When the electromagnet is energized, a magnetic force is generated, which attracts the iron core 1202 to drive the plug 1201 toward the electromagnet to an open position. At this time, the spring 1203 is compressed, and the plug 1201 leaves the first opening a102. When the electromagnet is no longer energized, under the elastic force of the spring 1203, the iron core 1202 drives the plug 1201 to return to the closed position to block the first opening a102. In an alternative embodiment, the moving assembly includes an electric cylinder and a plug 1201 , wherein the plug 1201 is connected to the end of a push rod of the electric cylinder, and the push rod of the electric cylinder can drive the plug 1201 to move.

[0146] Based on the above embodiment, in a preferred embodiment, the direction from the left side to the right side of the first wall panel a105 is defined as the width direction, and the direction from the bottom end to the top end of the first wall panel a105 is defined as the height direction. The width of the second chamber is smaller than the width of the first chamber, and the height of the second chamber is smaller than the height of the first chamber. In this embodiment, because the width of the second chamber is smaller than the width of the first chamber, and the height of the second chamber is smaller than the height of the first chamber, that is, the volume of the second chamber is smaller than the volume of the first chamber, the disinfectant water can quickly flow out through the water outlet a12 after entering the second chamber.

[0147] Based on the above embodiment, in a preferred embodiment, the distance between the first wall panel a105 and the second wall panel a106 is less than the width of the second chamber. In this embodiment, due to the small distance between the first wall panel a105 and the second wall panel a106, the water storage structure a1 is generally flat, occupying a small space, and there is no need to increase the gap between the inner container 1 and the outer shell.

[0148] Based on the above embodiment, in a preferred embodiment, the fluid discharge portion a5 is provided on the first wall panel a105 and passes through the side wall of the inner liner 1. Specifically, a second mounting hole is provided on the inner liner 1, and the fluid discharge portion a5 is provided through the second mounting hole. In this embodiment, by having the fluid discharge portion a5 pass through the side wall of the inner liner 1, the provision of a connecting pipe between the fluid discharge portion a5 and the inner liner 1 is reduced. At the same time, the fluid discharge portion a5 is embedded in the second mounting hole, supporting the water storage structure a1, and further ensuring that the water storage structure a1 is firmly connected. Of course, in other alternative embodiments, the fluid discharge portion a5 can be connected to the inner liner 1 through a connecting pipe.

In this embodiment, the lamp h2 is sealed within the lampshade h1, preventing water from entering the lamp h2 and ensuring its service life. The nut h4 prevents the lampshade h1 from falling off the inner door 1101, ensuring a secure connection between the lamp h2 and the inner door 1101.

[0171] like Figure 37 As shown, the blocking portion h101 is sealed to the inner door 1101 via a second sealing structure h5, which is specifically a sealing ring.

[0172] Further references Figure 37 The plate-shaped connecting portion a10 is provided with a lampshade h1 connection hole. The annular structure h102 passes through the mounting hole and the lampshade h1 connection hole in sequence. The nut h4 is screwed onto the annular structure h102 and rests against the plate-shaped connecting portion a10. In this embodiment, the nut h4 not only secures the water storage structure a1 to the door body 11, but also secures the lamp h2 to the inner door 1101, resulting in a simple and compact structure.

[0174] This embodiment provides a dishwasher. In one embodiment, Figures 39 to 46 As shown, the dishwasher includes a washing component, an air outlet mechanism f1, an air duct f2, a wind shield f3, a driving mechanism f4 and a disinfectant water generating device a. The washing component includes an inner tank 1. Figure 39 、 Figure 40 As shown, air duct f2 has an air inlet f21, a first air outlet f22, and a second air outlet f23. Air inlet f21 is connected to the air outlet of air outlet mechanism f1. First air outlet f22 is connected to the inner container 1 of the dishwasher. Windshield f3 is disposed in air duct f2 and is suitable for blocking first air outlet f22 or second air outlet f23. Drive mechanism f4 is connected to windshield f3. Drive mechanism f4 is suitable for driving windshield f3 to block first air outlet f22 or second air outlet f23. The structure of disinfectant water generating device a is the same as that of disinfectant water generating device a in the above embodiment and will not be described in detail in this embodiment.

[0175] During the research and development process, the applicant discovered that air needs to be introduced during the drying process of the inner tank 1 of the dishwasher. Air also needs to be introduced into the disinfectant water generating device a during use. This results in the need for multiple air outlet mechanisms f1 during use of the dishwasher, which makes the dishwasher complex in structure and high in manufacturing cost. Therefore, the dishwasher of this embodiment is also provided with an air duct f2 connected to the air outlet mechanism f1. The air duct f2 is provided with an air shield f3 and a drive mechanism f4. The air inlet f21 of the air duct f2 is connected to the air outlet of the air outlet mechanism f1. The first air outlet f22 is connected to the inner tank 1 of the dishwasher; the second air outlet f23 is connected to the air inlet a73 of the disinfectant water generating device a. This allows the drive mechanism f4 to drive the air shield f3 to block the first air outlet f22 when the disinfectant water generating device a needs to prepare disinfectant water, so that the air outlet mechanism f1 can introduce air into the disinfectant water generating device a.

[0176] When the dishwasher completes its operation, the drive mechanism f4 drives the air shield f3 to block the second air outlet f23, allowing the air outlet mechanism f1 to flow air into the inner container 1, thereby drying the inner container 1 and preventing secondary contamination of the dishes. Because the disinfectant water generator a does not prepare disinfectant water and dry the inner container 1 simultaneously, the dishwasher of this embodiment utilizes a single air outlet mechanism f1 to supply air to both the disinfectant water generator a and the inner container 1. Therefore, the dishwasher of this application overcomes the technical issues of complex structure and high manufacturing costs caused by the large number of air outlet mechanisms f1, simplifying the structure of the disinfectant water generator a and reducing its manufacturing costs.

[0177] In a preferred embodiment, the air inlet f21 of the air duct f2 is sealed to the air outlet of the air outlet mechanism f1.

[0178] The connection between the windshield member f3 and the air duct f2 is not limited to a hinged or sliding connection. Figure 39As shown, when the windshield f3 is hinged to the air duct f2, the windshield f3 is rotatably arranged in the air duct f2, and the driving mechanism f4 is used to drive the windshield f3 to rotate. When the driving mechanism f4 is used to drive the windshield f3 to rotate, the driving mechanism f4 can be selected as a device that can output rotation. For example, one of an electric motor, an engine, a hydraulic motor, or a combination of one of them and a reducer. When the windshield f3 is slidably connected to the air duct f2, the driving mechanism f4 is used to drive the windshield f3 to slide. In this case, the driving mechanism f4 can be selected as a device that can output linear motion. For example, a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, or a combination of a motor and a gear rack. The windshield f3 can be selected to be prismatic, but in order to increase the contact area between the windshield f3 and the inner wall of the air duct f2, thereby improving the sealing performance between the windshield f3 and the inner wall of the air duct f2, the windshield f3 is preferably a column with a fan-shaped axial cross-section. The side wall of the air duct f2 is provided with a concave cavity f24 that can match and accommodate the column. The hinge point of the wind deflector f3 is the center of the fan-shaped circle. The second air outlet f23 is formed in the concave cavity f24. The air inlet f21 is located at the first end of the air duct f2, and the first air outlet f22 is located at the second end of the air duct f2. Preferably, the circumferential length of the fan-shaped circle is greater than the circumferential dimensions of the first and second air outlets f22, f23, but less than the circumferential distance between the first and second air outlets f22, f23. This enables the drive mechanism f4 to rotate the main body along the hinge point and selectively block either the first or second air outlet f22, f23.

[0179] The drive mechanism f4 can be optionally mounted on the inner container 1, on the side wall of the dishwasher, or on the air duct f2. However, to avoid interference between the drive mechanism f4 and other structures within the dishwasher, the drive mechanism f4 is preferably mounted on the outer wall of the air duct f2, with a drive mechanism connection structure provided between the main body of the drive mechanism f4 and the air duct f2. The drive mechanism connection structure preferably includes, but is not limited to, a snap-fit ​​assembly, a riveted assembly, and a threaded connection assembly. For example, in this embodiment, the main body of the drive mechanism f4 is mounted on a drive mechanism mounting base, which is provided with a drive mechanism lug, and a connecting protrusion is provided on the outer wall of the air duct f2. The connecting protrusion is capable of engaging with the drive mechanism lug to securely connect the mounting base to the outer wall of the air duct f2.

[0180] In this embodiment, the dishwasher further includes a first stop protrusion f25 and a second stop protrusion f26 provided on the air duct f2. Figure 40 、 Figure 41 、 Figure 42 and Figure 43As shown, the windshield member f3 can block the first air outlet f22 when it abuts the first stop protrusion f25. It can also block the second air outlet f23 when it abuts the second stop protrusion f26. Therefore, the first stop protrusion f25 and the second stop protrusion f26 prevent the windshield member f3 from rotating beyond the intended angle, thus preventing the incorrect air outlet from being exposed due to excessive rotation of the windshield member f3.

[0181] In order to prevent the water in the inner tank 1 from flowing back into the air duct f2 and causing damage to the air outlet mechanism f1, the air duct f2 is preferably configured to include an ascending section f27 and a descending section f28 connected to each other. Figure 46 As shown. The air inlet f21 is located on the rising section f27, and the first air outlet f22 is located on the falling section f28. This ensures that even if water in the inner liner 1 enters the air duct f2, it cannot smoothly pass through the rising section f27, but will flow back into the inner liner 1 along the rising section f27, thereby protecting the air outlet device. The second air outlet f23 can be located on the rising section f27 or on the falling section f28. However, to facilitate the connection of the second air outlet to the disinfectant water generating device a, the second air outlet f23 is preferably located on the rising section f27.

[0182] In this embodiment, the air duct f2 is further provided with reinforcing ribs f29. This enhances the mechanical strength of the air duct f2. The ribs f29 preferably extend in the same direction as the air duct f2, thereby providing a certain degree of guidance for the air blown out by the air outlet.

[0183] In this embodiment, if Figure 44 and 45 As shown, the air duct f2 is preferably configured to include a first half-shell f201 and a second half-shell f202 that can be snapped together. The air inlet f21 is formed in the first half-shell f201. A cavity f24 is formed in the second half-shell f202. This allows the operator to quickly and easily install the windshield f3 in the cavity f24 on the second half-shell f202, and then snap the first half-shell f201 into the second half-shell f202, significantly simplifying the installation of the air duct f2.

[0184] Example 7

[0185] This embodiment provides a dishwasher. In one embodiment, the dishwasher includes a water inlet pipe assembly, a power supply device b, a disinfectant water generating device a, a liquid level sensor e, and a control module. The first end of the water inlet pipe assembly is connected to a water source. The water inlet pipe assembly includes an inlet valve. The structure of the disinfectant water generating device a is the same as that in the above embodiment and will not be described in detail in this embodiment. Figure 2As shown, a liquid level sensor e is disposed within the water storage structure a1 and is capable of emitting a first signal upon detecting that the water in the water storage structure a1 has reached a predetermined height. The predetermined height is higher than the height of the water outlet a12 and lower than the height of the fluid discharge portion a5. A control module is in communication with the liquid level sensor e and the water inlet valve and is capable of controlling the water inlet valve to switch to a closed state upon receiving the first signal. The power supply device can provide high voltage electricity to the discharge electrode and can be a power supply or other device capable of providing high voltage electricity.

[0186] The control module may include a programmable logic control unit (such as a PLC or CPU), a memory, and electronic components connected to the programmable logic control unit, etc., which are well known to those skilled in the art and will not be described in detail here. In a preferred embodiment, the predetermined height is set based on the amount of disinfectant water required by the dishwasher to prepare each time the dishware is disinfected. This allows the liquid level sensor e to not only prevent water from overflowing from the water storage structure a1 but also avoid replacing the flow meter to monitor the water level in the water storage structure a1. Even if the flow meter malfunctions, the liquid level sensor e can still generate a first signal when the water in the water storage structure a1 is sufficient to prepare the disinfectant water required for the disinfection operation, thereby ensuring that the water level in the water storage structure a1 is suitable for the disinfection operation.

[0187] During the research and development process, the applicant discovered that current dishwashers rely on flow meters to control the amount of water entering the water storage structure a1. A malfunction in the flow meter can lead to uneven concentrations in the disinfectant water, compromising the dishwasher's disinfection effectiveness. Water in the water storage structure a1 can even leak out of the vent, causing a short circuit in the dishwasher's circuitry and potentially leading to a safety incident.

[0188] Therefore, the dishwasher of this embodiment also incorporates a liquid level sensor e in the water storage structure a1. When the liquid level sensor e detects that the water in the water storage structure a1 has reached a predetermined height, the liquid level sensor e emits a first signal, causing the control module to receive the first signal and control the water inlet valve on the water inlet pipe assembly to switch to a closed state, thereby stopping the supply of water to the water inlet a11 of the water storage structure a1. Therefore, the dishwasher of this embodiment can control the amount of water entering the water storage structure a1 with the help of a flow meter. If the flow meter fails, the liquid level sensor e can also replace the flow meter to determine whether the water in the water storage structure a1 is suitable for preparing disinfectant water. Therefore, the water storage structure a1 of this embodiment overcomes the drawback of dishwashers in the prior art that cannot promptly stop the water supply to the water storage structure a1 when the flow meter fails, prevents water from flowing out of the overflow port, and reduces the risk of safety accidents caused by this.

[0189] Since the electrodes will discharge and electrolyze the medium in the water storage structure a1 when the dishwasher is in operation, the water in the water storage structure a1 will also be charged, which makes many common liquid level sensors e unable to be used in the water storage structure a1 of this embodiment. After multiple tests, the applicant confirmed that the liquid level sensor e can be selected from capacitive liquid level sensors e and photoelectric liquid level sensors e. However, in this embodiment, the liquid level sensor e preferably includes a reed switch e1 fixedly arranged in the water storage structure a1 and located at a predetermined height, and a magnetic component e2 movable in the vertical direction. When the magnetic component e2 moves to align with the reed switch e1, the spring sheet in the reed switch e1 can be connected under the action of the magnetic field, thereby sending a first signal to the control module. In an alternative embodiment, the liquid level sensor e is a photoelectric liquid level sensor, which is embedded in the side wall of the water storage structure a1. When the water in the water storage structure a1 reaches a predetermined height, the water can submerge the lens of the photoelectric liquid level sensor. The light emitted by the light-emitting diode cannot be received by the photosensitive receiver or only a small amount can be received by the photosensitive receiver after being refracted by the water. When sensing this working condition change, the photoelectric liquid level sensor can send a first signal to the control module, so that the control module controls the water inlet pipeline assembly to stop supplying water to the water storage structure a1.

[0190] The reed switch e1 can be fixed at a predetermined height via various protruding structures provided within the water storage structure a1, or it can be embedded in the sidewall of the water storage structure a1. Preferably, an insulating riser a9 is provided vertically within the water storage structure a1. The reed switch e1 is disposed within the insulating riser a9 and fixed at a predetermined height. The magnetic component e2 is sleeved onto the insulating riser a9 and has a density less than that of water. The magnetic component e2 can optionally include a magnet or a lodestone. To ensure that the density of the magnetic component e2 is less than that of water, the surface of the magnet or lodestone can be coated with a lightweight material. Lightweight materials are preferably, but not limited to, foam or plastic. The magnetic component e2, with a density less than that of water, can adjust its height as the water level changes. When the water in the water storage structure a1 reaches a predetermined height, the magnetic component e2, under the buoyancy of the water, can also reach the predetermined height, thereby aligning with the reed switch e1 within the insulating riser a9. This enables the spring sheets in the reed switch e1 to connect under the action of the magnetic field, thereby sending a first signal to the control module. The insulating riser a9 is configured to extend in the vertical direction, which can avoid friction between the insulating riser a9 and the magnetic component e2, preventing the magnetic component e2 from moving sensitively with changes in the water level in the water storage structure a1. The insulating riser a9 is preferably, but not limited to, made of insulating and smooth materials such as glass, ceramic, plastic or rubber. For example, in the present embodiment, the insulating riser a9 and the water storage structure a1 are made of the same material and are an integrally molded structure with the water storage structure a1. This can reduce the risk of water entering through the gap between the water storage structure a1 and the insulating riser a9 and damaging the reed switch e1. In order for the reed switch e1 to be fixed at a predetermined height, the reed switch e1 is preferably sealed in the insulating riser a9.

[0192] This embodiment provides a dishwasher. In one embodiment, the dishwasher includes a washing assembly, a disinfectant water generating device a, and a power supply device b. The structure of the disinfectant water generating device a is the same as that in the above embodiment, and will not be described in detail in this embodiment. Figure 47 As shown, the disinfectant water generating device a has a fluid discharge portion a5, and the outlet of the fluid discharge portion a5 is close to the power supply device b.

[0193] In this embodiment, the provision of fluid discharge portion a5 allows for the timely discharge of gases generated within water storage structure a1, ensuring pressure balance within water storage structure a1. Furthermore, when the water level within water storage structure a1 reaches fluid discharge portion a5, the fluid overflows through fluid discharge portion a5, ensuring pressure balance within water storage structure a1. By directing the outlet of fluid discharge portion a5 toward power supply device b, ozone generated within water storage structure a1 is promptly decomposed by the high temperature of power supply device b, preventing harm to the human body.

[0194] Based on the above embodiment, in a preferred embodiment, the fluid discharge portion a5 is disposed on the top wall of the water storage structure a1, near the power supply device b, and extends toward the power supply device b. In this embodiment, the fluid discharge portion a5 is relatively close to the power supply device b, eliminating the need for a pipeline to be connected to the outlet of the fluid discharge portion a5, resulting in a relatively simple structure.

[0195] Example 9

[0196] This embodiment provides a dishwasher, such as Figures 48 to 51 As shown, it includes a disinfectant water generating device a and a fluid driving mechanism d. The structure of the disinfectant water generating device a is the same as that in the above embodiment and will not be described in detail in this embodiment. The fluid driving mechanism d is arranged on the water storage structure a1 and is used to drive the water flow in the water storage structure a1.

[0197] During the research and development process, the applicant discovered that the disinfectant generated by electrolysis is often concentrated near the electrodes, which leads to uneven distribution of the disinfectant in the water storage structure a1, which is not conducive to the full progress of the electrolysis reaction, easily affects the concentration of the disinfectant, and hinders the improvement of the disinfection and sterilization effect of the dishwasher. Therefore, the disinfectant water generating device a of this embodiment is equipped with a fluid driving mechanism d in the water storage structure a1, such as Figure 48 、 Figure 49 and Figure 50 As shown, this enables the fluid drive mechanism d to drive the water in the water storage structure a1, thereby promoting the uniform distribution of the disinfectant water produced by the electrode discharge within the water storage structure a1, thereby promoting the full progress of the electrolysis reaction. Therefore, the disinfectant water generating device a of this embodiment can overcome the disadvantage of uneven disinfectant water concentration within the disinfectant water generating device a of the prior art, thereby promoting the full progress of the electrolysis reaction.

[0198] The fluid drive mechanism d is preferably, but not limited to, a magnetic stirrer and a combination of a rotation source d1 and an impeller d2. When the fluid drive mechanism d selects the rotation source d1 and the impeller d2, the rotation source d1 is fixedly mounted outside the water storage structure a1 and connected to the water storage structure a1. The impeller d2 is disposed within the water storage structure a1 and driven by the rotation source d1. The rotation source d1 can be selected from among an electric motor, an engine, a hydraulic motor, or a combination of one of these and a speed reducer. In order to ensure that the main body of the rotation source d1 can be stationary relative to the water storage structure a1, the rotation source d1 can be fixedly mounted on the side wall of the water storage structure a1, or can be fixedly mounted on the side wall of the dishwasher.

[0199] When the power supply device b is arranged close to the water storage structure a1, the fluid drive mechanism d can also be arranged to be fixedly connected to the power supply device b. Figure 47As shown, in this embodiment, the water storage structure a1 and the power supply device b are both disposed in the base recess 201 of the dishwasher. The main body of the rotation source d1 is disposed in the rotation source fixing seat. One end of the rotation source fixing seat is fixedly connected to the water storage structure a1, and the other end is fixedly connected to the power supply device. A first fixing seat connection structure is disposed between the rotation source fixing seat and the power supply device b. A second fixing seat connection structure is disposed between the rotation source fixing seat and the water storage structure. Both the first fixing seat connection structure and the second fixing seat connection structure are preferably, but not limited to, a snap-on assembly, a riveted assembly, and a threaded connection assembly.

[0200] For example, in this embodiment, a first fixing seat lug is provided on one end of the rotating source fixing seat, and a water storage structure a1 mounting hole corresponding to the first fixing seat lug is provided on the water storage structure a1. The first fixing seat lug and the water storage structure a1 mounting hole can allow a connecting column or screw to be inserted when aligned to securely connect the water storage structure a1 and the rotating source fixing seat. A second fixing seat lug is also provided on the other end of the rotating source fixing seat. A power supply device mounting hole corresponding to the second fixing seat lug is provided on the power supply device b. The second fixing seat lug and the power supply device mounting hole can allow a connecting column or screw to be inserted when aligned to securely connect the power supply device b and the rotating source fixing seat.

[0201] In this embodiment, if Figure 51 As shown, when the fluid drive mechanism d is selected as a combination of a rotation source d1 and an impeller d2, to further improve the sealing performance of the water storage structure a1, the disinfectant water generating device a preferably also includes a through hole and a water storage structure sealing ring d3. The through hole is provided in the wall of the water storage structure a1, and the rotating shaft of the impeller d2 passes through the through hole. The water storage structure sealing ring d3 is mounted on the rotating shaft of the impeller d2 and is capable of blocking the gap between the through hole and the rotating shaft. The water storage structure sealing ring d3 is preferably, but not limited to, made of a material with sufficient elasticity and resilience and suitable mechanical strength, such as rubber or silicone.

[0202] Example 10

[0203] This embodiment provides a dishwasher, including a washing assembly, a disinfectant 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 suitable for cooling the power supply device b. The washing assembly, the disinfectant water generating device a, and the power supply device b are the same as those in the above embodiments, and will not be described in detail in this embodiment. Figure 52 As shown, the cooling module c is connected to the power supply device b and is suitable for cooling the power supply device b.

[0204] During the research and development process, the applicant discovered that during use of the dishwasher, the power supply device b is prone to heating up, which accelerates the aging of the power supply device b and even creates safety hazards. Therefore, the dishwasher of this embodiment also 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 down and prevent the heat from accelerating the aging of the power supply device b. Therefore, the power supply device b of this embodiment can overcome the defect that the power supply device b is prone to heating up during use, which accelerates the aging of the power supply device b and creates safety hazards. This 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.

[0205] The cooling module c is preferably, but not limited to, an air cooling device or a liquid cooling device. Figure 53 As shown, in this embodiment, the cooling module c is a liquid cooling device and includes a housing c1. Housing c1 has a cooling medium inlet c2 and a cooling medium outlet c3. The cooling medium inlet c2 of housing c1 is used to receive cooling medium. The surface of housing c1 is in surface contact with the power supply device b, thereby cooling the power supply device b. The cooling medium outlet c3 discharges the cooling medium after heat exchange. The cooling medium can be water or other heat transfer fluids such as Freon, ammonia, or tetrafluoroethane.

[0206] The cooling medium inlet c2 of the housing c1 can be directly connected to a water source. However, preferably, the dishwasher further includes a water inlet piping assembly, a water channel switching structure, and a washing assembly. The first end of the water inlet piping assembly is connected to the water source. The water channel switching structure is disposed between the second end of the water inlet piping assembly, the cooling module c, and the disinfectant water generator a. The water inlet piping assembly has a first state in which it communicates with the cooling medium inlet c2 of the cooling module c, and a second state in which it communicates with the disinfectant water generator a. The washing assembly is connected to the cooling medium outlet c3 of the housing c1.

[0207] Therefore, when the dishwasher needs to disinfect the tableware, the water circuit switching structure can first switch to the second state and connect the water inlet pipe assembly with the disinfectant water generating device a, thereby supplying water to the disinfectant water circuit generating device. When the amount of water in the disinfectant water generating device a is sufficient, the water circuit switching structure can switch to the first state and connect the water inlet pipe assembly with the cooling medium inlet c2 of the cooling module c. At this time, the power supply device b starts to supply power to the disinfectant water generating device a, and the water inlet pipe 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 allows 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 with the washing water required for cleaning the tableware, without consuming additional water or equipping a power source, thereby improving energy utilization.

[0208] When the dishwasher does not need to sterilize dishes, the water circuit switching mechanism switches directly to the first state, connecting the water inlet pipe assembly to the cooling medium inlet c2 of the cooling module c. The water inlet pipe assembly can then supply water to the cooling medium inlet c2 of the cooling module c. The cooling medium outlet c3 of the housing c1 is connected to the washing assembly, allowing the cooling water to enter the washing assembly after passing through the cooling module c and wash the dishes.

[0209] In this embodiment, the box body c1 can be configured to be in surface contact with any side surface of the power supply device b. However, in order to improve the space utilization rate in the dishwasher and the installation stability of the power supply device b, the box body c1 is preferably configured to be a flat structure. The power supply device b is fixedly mounted 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 circuitous water channel, such as a serpentine water channel c4. Figure 54 As shown, when the water channel in the box body c1 is a serpentine water channel, the cooling medium inlet c2 and the cooling medium outlet c3 are preferably located at the two ends of the serpentine water channel 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 further provided between the power supply device b and the box body c1. Figure 53 As shown, the heat conducting plate c5 is preferably, but not limited to, made of a heat conducting material such as steel, aluminum, or silicone. To further increase its heat conduction efficiency, the heat conducting plate c5 may also be provided with a flow channel and a heat conducting medium capable of flowing in the flow channel, such as mineral oil or ethylene glycol. These are well known to those skilled in the art and will not be described in detail here.

[0210] In this embodiment, to securely fasten the power supply device b to the housing c1, a connection assembly is preferably provided between the power supply device b and the heat conducting plate c5. The connection assembly can be a snap-fit ​​assembly, a riveted assembly, or a threaded connection assembly, but preferably, power supply lugs are provided at both ends of the power supply device b. Heat conducting plate c5 has heat conducting plate connection holes at positions corresponding to the connection lugs. The power supply lugs and the heat conducting plate connection holes cooperate to securely connect the power supply device b to the heat conducting plate c5.

[0211] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
