The present embodiment provides a dishwasher.

In one embodiment, a dishwasher includes a washing assembly, an air outlet mechanism f1, an air duct f2, a wind shield f3, a driving mechanism f4, and a sterilizing water generating device a. Wherein the washing assembly comprises a liner 1 (see fig. 9). As shown in fig. 1, the air duct f2 has an air inlet f21, a first air outlet f22, and a second air outlet f23. The air inlet f21 is connected with an air outlet of the air outlet mechanism f 1. The first air outlet f22 is communicated with the inner container 1 of the dish washer. The wind shielding piece f3 is arranged in the air duct f2 and is suitable for blocking the first air outlet f22 or the second air outlet f23. The driving mechanism f4 is connected to the wind shielding member f 3. The driving mechanism f4 is suitable for driving the wind shielding member f3 to block the first air outlet f22 or the second air outlet f23. The sterilizing water generating device a includes an air inlet passage adapted to be introduced with air. The second air outlet f23 is communicated with the air inlet channel. The power supply device b may be a high-frequency high-voltage device, or may be other devices capable of providing high-voltage power, for example, the power supply device b includes a 220V power source and a transformer connected to the power source. The discharge electrode a2 is connected with the live wire b1 of the transformer, and the return electrode a3 is connected with the zero line b2 of the transformer. The connection between the air inlet f21 and the air outlet of the air outlet mechanism f1 is preferably a sealing connection.

According to the technical scheme, when the sterilizing water is needed to be prepared, tap water enters the water storage structure a1, the power supply device b provides high-frequency alternating voltage of about 6-15KV for the discharge electrode a2, air enters the water storage structure a1 through the air inlet channel, glow discharge phenomenon occurs on the discharge electrode a2 of the sterilizing water generating device a, high-energy electrons and air and water molecules are reacted vigorously around the gas/liquid interface during discharge to generate plasmas with strong oxidizing capability on bacteria and viruses, and the plasmas with strong sterilizing capability on ozone ion groups, hydrogen peroxide ion groups, hydroxyl groups, nitroso groups and the like are generated, so that the sterilizing effect of the sterilizing water is superior to that of the conventional sterilizing modes such as high-temperature sterilization, steam sterilization, ultraviolet sterilization, silver ion sterilization and the like; when the disinfection work is needed, the switch element is turned on, so that the disinfection water generated in the water storage structure a1 flows into the water cup 3 of the dish washer and is mixed with water in the water cup 3 for dilution, the washing pump 14 pumps the disinfection water in the water cup 3 into the spray arm, the spray arm sprays the disinfection water to the inner container 1 and tableware in the inner container 1 to disinfect the tableware, and the disinfection water flows into the water cup 3, the washing pump 14, the spray arm and the inner container 1 to disinfect the tableware in all directions, so that the disinfection effect is good. The sterilizing water discharged by the machine not only does not pollute the environment, but also has the function of purifying sewage.

In addition, during the development, the applicant found that air needs to be introduced during the drying of the inner tub 1 of the dishwasher. The sterilizing water generator a also needs to be supplied with air during use. This results in the need for a plurality of air outlet mechanisms f1 during use of the dishwasher, which results in a complicated structure of the dishwasher and high manufacturing costs. Therefore, the dishwasher of the present application is further provided with the air duct f2 connected to the air outlet mechanism f 1. The wind shielding member f3 and the driving mechanism f4 are provided in the wind tunnel f2. The air inlet f21 of the air duct f2 is connected with the air outlet of the air outlet mechanism f 1. The first air outlet f22 is connected with the inner container 1 of the dish washer; the second air outlet f23 communicates with the air inlet a73 of the sterilizing water generator a. This enables the driving mechanism f4 to drive the wind shielding member f3 to block the first air outlet f22 when the sterilizing water generating device a needs to prepare sterilizing water, so that the air outlet mechanism f1 can introduce air into the sterilizing water generating device a. The connection between the air inlet f21 of the air duct f2 and the air outlet of the air outlet mechanism f1 is preferably a sealing connection.

After the dish washer finishes working, the driving mechanism f4 can drive the wind shielding piece f3 to block the second air outlet f23, so that the air outlet mechanism f1 can introduce air into the liner 1 to dry the liner 1, and secondary pollution to tableware is avoided. Since the operation of preparing the sterilizing water by the sterilizing water generating device a and the operation of drying the inner container 1 are not simultaneously performed, the dishwasher of the present application can complete the operation of supplying air to the sterilizing water generating device a and the operation of supplying air to the inner container 1 by means of one air outlet mechanism f 1. Therefore, the dishwasher of the present application can also overcome the technical problems of complex structure and high manufacturing cost caused by the large number of the air outlet mechanisms f1, and can simplify the structure of the sterilizing water generating device a and reduce the manufacturing cost thereof.

The connection relationship of the wind shielding member f3 and the air duct f2 is not limited to a hinge or a slide connection. For example, when the wind shielding member f3 is hinged to the air duct f2, the wind shielding member f3 is rotatably disposed in the air duct f2, and the driving mechanism f4 is used for driving the wind shielding member f3 to rotate. When the driving mechanism f4 is used to drive the wind shielding member f3 to rotate, the driving mechanism f4 may be selected as a device capable of outputting rotation. Such as a combination of one or more of an electric motor, an engine, a hydraulic motor, and a speed reducer, etc. When the wind shielding piece f3 is in sliding connection with the air duct f2, the driving mechanism f4 is used for driving the wind shielding piece f3 to slide. The driving mechanism f4 may be selected to be a device capable of outputting linear motion. Such as a hydraulic cylinder, a pneumatic cylinder, an electric cylinder or a combination of a motor and a rack and pinion, etc. The wind shielding member f3 may be selected to be prismatic, but in order to increase the contact area between the wind shielding member f3 and the inner wall of the air duct f2, thereby improving the sealing performance between the wind shielding member f3 and the inner wall of the air duct f2, as shown in fig. 2,3, 4 and 5, the wind shielding member f3 is preferably a cylinder having a fan-shaped axial section. The side wall of the air duct f2 is provided with a concave cavity b24 which can be matched to accommodate the column body. The hinge point of the wind shielding piece f3 is the center of the fan shape. The second air outlet b23 is formed on the concave cavity b24, the air inlet b21 is arranged on the first end of the air channel f2, and the first air outlet b22 is arranged on the second end of the air channel f 2. Preferably, the circumferential length of the fan shape is greater than the circumferential dimensions of the first air outlet b22 and the second air outlet b23 and less than the circumferential distance between the first air outlet b22 and the second air outlet b23. This enables the driving mechanism f4 to drive the main body to rotate along the hinge point and selectively block the first air outlet b22 or the second air outlet b23.

The driving mechanism f4 may alternatively be provided on the liner 1, on a side wall of the dishwasher, or on the air channel f 2. However, in order to avoid interference of the driving mechanism f4 with other structures in the dishwasher, the driving mechanism f4 is preferably provided on an outer wall of the air duct f2, and a driving mechanism f4 connection structure is provided between a main body of the driving mechanism f4 and the air duct f 2. The drive mechanism f4 connection structure is preferably but not limited to a snap-in assembly, a rivet assembly, a threaded connection assembly, etc. For example, in the present embodiment, the main body portion of the driving mechanism f4 is disposed in the driving mechanism f4 mounting seat, the driving mechanism f4 ear plate is disposed on the driving mechanism f4 mounting seat, and the connecting protrusion is disposed on the outer wall of the air duct f 2. The connecting protrusion can be matched with the ear plate of the driving mechanism f4 and fixedly connect the mounting seat with the outer wall of the air duct f 2.

In this embodiment, the dishwasher further includes a first stop protrusion f25 and a second stop protrusion f26 provided on the air duct f 2. As shown in fig. 2,3,4 and 5, the wind shielding member f3 can block the first air outlet f22 while abutting against the first stopper protrusion f 25. And closes the second air outlet f23 while abutting against the second stopper protrusion f26. Therefore, the first and second stopper protrusions f25 and f26 can prevent the deflection angle of the wind shielding member f3 from exceeding the expected angle, and prevent the erroneous air outlet from being exposed due to excessive rotation of the wind shielding member f 3.

In order to avoid water in the liner 1 flowing back into the air channel f2, the air outlet mechanism f1 is damaged. The air duct f2 is preferably provided to include a rising section f27 and a falling section f28 connected to each other, as shown in fig. 8. The air inlet f21 is arranged on the rising section f27, and the first air outlet f22 is arranged on the falling section f 28. This makes even if water in the liner 1 enters the air duct f2, it does not pass through the rising section f27 smoothly, but flows back into the liner 1 along the rising section f27, thereby functioning as a protection air outlet device. The second air outlet f23 is optionally arranged on the rising section f27, and is optionally arranged on the falling section f 28. However, in order to facilitate the connection of the second air outlet to the sterilizing water generator a, the second air outlet f23 is preferably provided at the rising section f 27.

In this embodiment, the air duct f2 is further provided with a reinforcing rib f29. The mechanical strength of the air duct f2 can be enhanced. The extending direction of the reinforcing rib f29 is preferably set to be the same as the extending direction of the air duct f 2. Can play a certain drainage role to the air blown out by the air outlet device.

In the present embodiment, as shown in fig. 6 and 7, the air duct f2 is preferably provided to include a first half-shell f201 and a second half-shell f202 that can be fastened to each other. The air inlet f21 is formed in the first half case f 201. A cavity f24 is formed in the second half-shell f202. The wind shield f3 can be conveniently and rapidly installed in the concave cavity f24 on the second half shell f202 by an operator, and then the first half shell f201 and the second half shell f202 are buckled, so that the installation difficulty of the air duct f2 is greatly reduced.
