[0046] Washing dishes is an essential part of daily life. The oil stains on the dishes can easily lead to greasy hands. At the same time, people's pace of life is getting faster and faster, and the cleaning efficiency is low and the time is long during the daily dishwashing process. Therefore, dishwashers are increasingly widely used in people's daily lives.

[0047] In the related art, the working process of a dishwasher is divided into a washing stage and a drying stage. In the washing stage, the dishwasher can spray hot water or cold water onto the dishes to remove dirt adhering to the dishes and clean the dishes. In the drying stage, the external air can be processed by an ion generator so that the treated gas has a bactericidal effect before entering the inner tank, thereby drying and sterilizing the tableware in the inner tank.

[0048] However, the air intake structure used in conjunction with the ion generator in a conventional dishwasher is relatively complex and requires the configuration of an additional air intake power device.

[0049] Based on this, the present application provides a dishwasher, which is used to solve the problem that the air intake structure of the conventional dishwasher that cooperates with the ion generator is relatively complicated and requires the configuration of an additional air intake power device. The specific structure and beneficial effects of the dishwasher in the present application will be described in detail below in conjunction with the accompanying drawings of the specification.

[0050] Figure 1 FIG. 1 shows one of the overall structural diagrams of the dishwasher provided in the embodiment of the present application, referring to FIG. Figure 1 In some embodiments of the present application, the dishwasher 1 may include a dishwasher body 10 , wherein the dishwasher body 10 has a dishwasher cavity 11 and an air exhaust port 12 and an air inlet 13 connected to the dishwasher cavity 11 .

[0051] In this way, the user can place items to be washed, such as bowls, plates, chopsticks or spoons, in the inner cavity 11 of the dishwasher, and the dishwasher 1 can control the air pressure in the inner cavity 11 through the exhaust port 12 and the air inlet 13 during operation.

[0052] Figure 2 The second schematic diagram of the overall structure of the dishwasher provided in the embodiment of the present application is shown. Figure 2In some embodiments of the present application, the inner cavity 11 of the dishwasher may also be provided with a plurality of bowl baskets, such as a first bowl basket 14 and a second bowl basket 15 arranged up and down. In this case, bowls, plates or tea cups may be placed in the upper first bowl basket 14, and chopsticks, spoons or knives and forks may be placed in the lower second bowl basket 15, so as to facilitate the user to store and organize after washing.

[0053] Figure 3 The third schematic diagram of the overall structure of the dishwasher provided in the embodiment of the present application is shown in conjunction with Figure 1 and Figure 3 In some embodiments of the present application, the dishwasher 1 may further include an exhaust assembly 20 connected to the dishwasher body 10, and the exhaust assembly 20 may include an exhaust channel 21, one end of the exhaust channel 21 is connected to the exhaust port 12, and the other end of the exhaust channel 21 is used to connect to the external space of the dishwasher 1.

[0054] In some embodiments of the present application, the dishwasher 1 may further include an airflow driving component 22 , which is disposed in the exhaust passage 21 and can drive the air in the dishwasher inner cavity 11 to enter the exhaust passage 21 .

[0055] In this way, during the drying stage of the dishwasher 1, the airflow driving component 22 can be started to transport the hot and humid air in the inner cavity 11 of the dishwasher to the external environment of the dishwasher 1 through the exhaust port 12 and the exhaust channel 21, so that the air pressure in the inner cavity 11 of the dishwasher is lower than the air pressure in the external environment of the dishwasher 1.

[0056] Figure 4 The fourth schematic diagram of the overall structure of the dishwasher provided in the embodiment of the present application is shown in conjunction with Figure 1 , Figure 3 and Figure 4 In some embodiments of the present application, the dishwasher 1 may further include a sterilization component 30 connected to the dishwasher body 10. The sterilization component 30 may include an air inlet channel 31. One end of the air inlet channel 31 is connected to the air inlet 13, and the other end of the air inlet channel 31 is used to connect to the external space of the dishwasher 1.

[0057] In this way, during the drying stage of the dishwasher 1, after the exhaust component 20 gradually empties the hot and humid air in the inner cavity 11 of the dishwasher, the dry and low-temperature air in the external environment flows into the inner cavity 11 of the dishwasher through the air inlet channel 31 and the air inlet 13 under the action of atmospheric pressure, thereby drying the tableware in the inner cavity 11 of the dishwasher.

[0058] In some embodiments of the present application, the sterilization component 30 may further include an ion generator 32 , which is disposed in the air inlet channel 31 and is used to ionize the air in the air inlet channel 31 to generate charged ions.

[0059] In this way, after the charged ions enter the inner cavity 11 of the dishwasher through the air inlet channel 31 and the air inlet 13, they will combine with water molecules to form active oxygen ions with strong oxidizing or reducing properties, such as hydroxyl radicals or superoxide ions, etc. The active oxygen ions can destroy the cell membrane and cell wall of microorganisms, causing their death. In addition, the active oxygen ions can also react with the proteins and nucleic acids of microorganisms, preventing their normal metabolism and growth, thereby achieving a sterilization effect.

[0060] Figure 5 The fifth schematic diagram of the overall structure of the dishwasher provided in the embodiment of the present application is shown in conjunction with Figure 1 and Figure 5 In some embodiments of the present application, the sterilization component 30 may further include a respirator 33, the respirator 33 may include an air inlet chamber, the air inlet chamber is located in the air inlet channel 31, the ion generator 32 includes an ionization chamber, the ionization chamber is located in the air inlet channel 31, and the ionization chamber is located on the side of the air inlet chamber away from the air inlet port 13.

[0061] In this way, the low-temperature dry air in the external environment of the dishwasher 1 can first enter the ionization chamber of the ion generator 32 to be ionized to produce active oxygen ions, and the low-temperature dry air carrying the active oxygen ions then enters the inner cavity 11 of the dishwasher through the air inlet cavity of the respirator 33 to sterilize and disinfect the tableware located in the inner cavity 11 of the dishwasher.

[0062] In summary, the present application provides an air inlet 13 and an air outlet 12 connected to the inner cavity 11 of the dishwasher body 10, the air inlet 13 is connected to the respirator 33 and the ion generator 32 to form an air inlet channel 31, and the air outlet is connected to the exhaust component 20 to form an air outlet channel. In the drying stage, the exhaust component 20 extracts the hot and humid air from the inner cavity 11 of the dishwasher, so that the air pressure in the inner cavity 11 of the dishwasher is lower than the air pressure of the external environment, thereby providing air intake power for the air inlet channel 31, and the dry gas in the external environment flows through the ion generator 32, the respirator 33 and the air inlet 13 in sequence under the action of atmospheric pressure and enters the inner cavity 11 of the dishwasher.

[0063] That is to say, the air inlet channel 31 of the dishwasher 1 provided in the present application and the ion generator 32 does not need to be additionally configured with other air inlet power devices, so that the dishwasher has a streamlined structure and can save energy and improve efficiency.

[0064] Figure 6 The structure diagram of the respirator provided in the embodiment of the present application is shown in conjunction with Figure 5 and Figure 6 In some embodiments of the present application, in the flow direction of the airflow along the air inlet channel 31, a plurality of blocking members 331 are arranged at intervals in the air inlet cavity.

[0065] In this way, when the dishwasher 1 is in the washing stage, the humid hot water vapor in the inner cavity 11 of the dishwasher will encounter a plurality of blocking members 331 arranged in the air inlet channel 31 during the process of flowing back along the air inlet channel 31. Since the temperature of the blocking members 331 is relatively low, part of the humid hot water vapor will condense and liquefy into small droplets on the blocking members 331 until the small droplets continue to accumulate and merge into large droplets, and under the action of their own gravity, they will slide down from the blocking members 331 and flow back to the inner cavity 11 of the dishwasher, thereby reducing the humid hot air discharged into the kitchen and the heat lost during the washing stage of the dishwasher 1.

[0066] It should be noted that the specific structure of each blocking member 331 can be various. For example, the blocking member 331 can be configured as follows: Figure 6 The slightly curved surface shown in FIG. 3 is conducive to promoting the liquefied droplets to slide off the blocking member 331. Exemplarily, the blocking member 331 can also be set to a flat surface.

[0067] In some embodiments of the present application, at least part of the projections of multiple blocking members 331 on a reference plane do not overlap, and the reference plane is a plane perpendicular to the airflow direction. That is, the blocking members 331 at different heights are staggered in the left-right direction.

[0068] In this way, when the humid hot water vapor in the inner cavity 11 of the dishwasher flows from bottom to top, due to the staggered arrangement of the blocking member 331, the flow path of the airflow becomes bent upward, which is beneficial to extend the flow path of the humid hot water vapor and make it fully contact with the blocking member 331, thereby promoting as much humid hot water vapor as possible to condense and liquefy and flow back to the inner cavity 11 of the dishwasher.

[0069] In some embodiments of the present application, the sterilization component 30 may further include an ozone generator, which is also disposed in the air inlet channel 31 and can convert the oxygen molecules O2 in the air inlet channel 31 into ozone molecules O3.

[0070] Thus, since ozone molecules O3 can decompose organic matter and eliminate odors and pollutants in the air, the ozone generator can be combined with the ion generator 32 to jointly process the dry air in the air inlet channel 31. After the dry air processed by the ion generator 32 and the ozone generator enters the inner cavity 11 of the dishwasher, it can effectively improve the cleaning and sterilization effect of the tableware placed in the inner cavity 11 of the dishwasher.

[0071] Figure 7 The structure diagram of the damper control assembly provided by the embodiment of the present application in the first position is shown. Figure 8 The structure diagram of the damper control assembly 23 provided in the embodiment of the present application in the second position is shown in conjunction with Figure 1 , Figure 7 and Figure 8 In some embodiments of the present application, the exhaust component 20 also includes a damper control component 23, and the damper control component 23 is used to control the opening and closing state of the exhaust port 12.

[0072] In some embodiments of the present application, the damper control assembly 23 may include a drive member and a valve body 232. The drive member may include a drive shaft 231, the drive shaft 231 can move toward the exhaust port 12, and the valve body 232 is connected to the drive shaft 231 and has a first position and a second position.

[0073] When the valve body 232 is in the first position, the valve body 232 is spaced apart from the exhaust port 12 , thereby opening the exhaust port 12 ; when the valve body 232 is in the second position, the valve body 232 abuts against the exhaust port 12 , thereby closing the exhaust port 12 .

[0074] It is understandable that when the dishwasher 1 is in the washing stage, the exhaust port 12 can be closed by the damper control assembly 23, so that the dishwasher cavity 11 is in a sealed state, thereby preventing the heat loss of the dishwasher cavity 11, ensuring the cleaning effect of the dishwasher 1, and preventing water from entering the exhaust assembly 20. When the dishwasher 1 is in the drying stage, the exhaust port 12 can be opened by the damper control assembly 23, so that the hot and humid air in the dishwasher cavity 11 is quickly discharged under the action of the exhaust assembly 20, thereby ensuring the drying efficiency of the dishwasher 1.

[0075] Fig. 9 One of the structural schematic diagrams of the exhaust assembly provided in the embodiment of the present application is shown, Fig.10 The second structural diagram of the exhaust assembly provided in the embodiment of the present application is shown in conjunction with Fig. 9 and Fig.10 In some embodiments of the present application, the exhaust assembly 20 may also include a first cavity 24 and a second cavity 25, the first cavity 24 is connected to the exhaust port 12, the second cavity 25 is connected to the external air, and the first cavity 24 and the second cavity 25 are both located in the exhaust channel 21.

[0076] In this way, the hot and humid air in the inner cavity 11 of the dishwasher can enter the first cavity 24 of the exhaust assembly 20 , and the dry air outside the dishwasher 1 can enter the second cavity 25 of the exhaust assembly 20 .

[0077] Fig.11 The third structural diagram of the exhaust assembly provided in the embodiment of the present application is shown in conjunction with Fig. 9 , Fig.10 and see Fig.11 In some embodiments of the present application, the exhaust assembly 20 may further include a condensation channel 26 , which is connected to both the first cavity 24 and the second cavity 25 .

[0078] In this way, the hot and humid air in the first cavity 24 and the low-temperature dry air in the second cavity 25 can flow into the condensation channel 26 and mix with each other. The low-temperature air can cool the high-temperature air and promote the condensation of the hot and humid air.

[0079] Fig.12 The fourth structural diagram of the exhaust assembly provided in the embodiment of the present application is shown in conjunction with Fig.11 and Fig.12 In some embodiments of the present application, the exhaust assembly 20 may further include an airflow driving assembly 22 , and the airflow driving assembly 22 may include a first rotating member 221 and a second rotating member 222 .

[0080] Among them, the first rotating member 221 is arranged in the first cavity 24, which can promote the air in the dishwasher cavity 11 to be sent into the condensation channel 26 through the first cavity 24, and the second rotating member 222 is arranged in the second cavity 25, which can promote the external air to be sent into the condensation channel 26 through the second cavity 25, thereby accelerating the condensation and emptying process of the hot and humid air in the dishwasher cavity 11, and improving the drying efficiency of the dishwasher 1.

[0081] In some embodiments of the present application, the air output of the first rotating member 221 is greater than the air output of the second rotating member 222 per unit time, so that the humid hot air flowing into the condensation channel 26 is greater than the dry air flowing into the condensation channel 26 .

[0082] In this way, the humid hot air can be promoted to be condensed by the low-temperature dry air at a suitable density, thereby improving the condensation efficiency of the humid hot air and the drying performance of the dishwasher 1. At the same time, it also reduces the uncondensed humid hot air discharged into the kitchen, thereby reducing the user's cleaning work.

[0083] There may be multiple implementation forms for the specific implementation form of the air output of the first rotating member 221 being greater than the air output of the second rotating member 222 .

[0084] In a possible structural design, combined with reference to Fig.10 and Fig.12 The airflow driving assembly 22 may further include a rotating substrate 223 , and the rotating substrate 223 is disposed between the first cavity 24 and the second cavity 25 .

[0085] In some embodiments of the present application, the first rotating member 221 may include a plurality of first blades 2210 disposed in the first cavity 24, the plurality of first blades 2210 being connected to the rotating substrate 223 and being arranged at intervals in the circumferential direction around the rotation center axis of the rotating substrate 223. Similarly, the second rotating member 222 may include a plurality of second blades 2220 disposed in the second cavity 25, the plurality of second blades 2220 being disposed on a side of the rotating substrate 223 away from the first blades 2210, and being arranged at intervals in the circumferential direction around the rotation center axis of the rotating substrate 223.

[0086] In this way, when the rotating substrate 223 rotates around the rotation center axis of the rotating substrate 223, the multiple first blades 2210 and the multiple second blades 2220 installed on both sides of the rotating substrate 223 can simultaneously drive the hot and humid air inside the dishwasher 1 to enter the condensation channel 26 through the first cavity 24, and the dry air outside the dishwasher 1 to enter the condensation channel 26 through the second cavity 25.

[0087] The plurality of first blades 2210 and the plurality of second blades 2220 are arranged in one-to-one correspondence, and the projection area of ​​the first blade 2210 on the reference plane is larger than the projection area of ​​the second blade 2220 arranged opposite to the first blade 2210 on the reference plane, and the reference plane is a plane perpendicular to the plane where the rotating substrate 223 is located. In other words, the surface area of ​​the first blade 2210 is larger than the surface area of ​​the second blade 2220.

[0088] It can be understood that when the surface area of ​​the first blade 2210 is larger than the surface area of ​​the second blade 2220, when a motor is used to drive the rotating substrate 223 to rotate, although the rotation speed of the rotating substrate 223 is constant, the air volume passing through the first cavity 24 and the second cavity 25 on both sides of the rotating substrate 223 per unit time is different. The surface area of ​​the first blade 2210 located in the first cavity 24 is larger and can drive more air flow. Therefore, the hot and humid air entering the condensation channel 26 from the dishwasher inner cavity 11 through the first cavity 24 is greater than the low-temperature dry air entering the condensation channel 26 through the second cavity 25.

[0089] It should be noted that, although most of the first cavity 211 and the second cavity 212 are separated by the rotating substrate 223, there is a gap between the outer ring of the rotating substrate 223 and the housing 21, and the first cavity 211 and the second cavity 212 can be connected through this gap. In this way, when the humid hot air enters the first cavity 211 and the dry air enters the second cavity 212, the humid hot air and the dry air are both transported to the gap part of the outer ring of the rotating substrate 223 under the action of centrifugal force, and the humid hot air and the dry air are fully mixed at the gap position, and then transported to the condensation channel 213, so as to promote the condensation efficiency of the humid hot air.

[0090] There may be many specific forms in which the surface area of ​​the first blade 2210 is greater than the surface area of ​​the second blade 2220 .

[0091] For example, Fig.13 FIG. 1 shows one of the structural schematic diagrams of the airflow drive assembly provided in the embodiment of the present application, referring to FIG. Fig.13 , along the arrangement direction of the first blade 2210 , the rotating substrate 223 and the second blade 2220 , the length of the first blade 2210 is greater than the length of the second blade 2220 .

[0092] Exemplarily, the length of the first blade 2210 along the radial extension direction of the rotating substrate 223 may be greater than the length of the second blade 2220 along the radial extension direction of the rotating substrate 223 .

[0093] In another possible structural design, Fig.14 FIG. 2 shows a second structural diagram of an airflow drive assembly provided in an embodiment of the present application. Fig.14 In some embodiments of the present application, the airflow drive assembly 22 may also include a first drive motor 224 and a second drive motor 225, the first drive motor 224 is connected to the first rotating member 221, and the second drive motor 225 is connected to the second rotating member 222, wherein the rotation speed of the first drive motor 224 is greater than the rotation speed of the second drive motor 225.

[0094] That is to say, the present application may not improve the first rotating member 221 or the second rotating member 222, but may use two independent motors to drive the first rotating member 221 and the second rotating member 222 to perform differential rotation, thereby achieving different air output volumes.

[0095] In summary, the dishwasher provided in this application mainly has the following advantages:

[0096] (1) The dishwasher 1 provided in the present application does not need to be equipped with any other air inlet power device in the air inlet channel 31 in cooperation with the ion generator 32, so that the dishwasher has a simple structure and can save energy and improve efficiency. In the drying stage, the exhaust assembly 20 extracts the hot and humid air from the inner cavity 11 of the dishwasher, so that the air pressure in the inner cavity 11 of the dishwasher is lower than the air pressure in the external environment, thereby providing air inlet power for the air inlet channel 31. The dry gas in the external environment flows through the ion generator 32, the respirator 33 and the air inlet 13 in sequence under the action of atmospheric pressure and enters the inner cavity 11 of the dishwasher;

[0097] (2) When the dishwasher 1 of the present application is in the washing stage, the hot and humid water vapor in the inner cavity 11 of the dishwasher will encounter a plurality of blocking members 331 disposed in the air inlet channel 31 during the process of flowing back along the air inlet channel 31. Since the temperature of the blocking members 331 is relatively low, part of the hot and humid water vapor will condense and liquefy into small droplets on the blocking members 331 until the small droplets continue to accumulate and merge into large droplets, and then slide down from the blocking members 331 under the action of their own gravity and flow back to the inner cavity 11 of the dishwasher, thereby reducing the hot and humid air discharged into the kitchen and the heat lost by the dishwasher 1 during the washing stage;

[0098] (3) When the humid hot water vapor flows from bottom to top in the inner cavity 11 of the dishwasher of the present application, due to the staggered arrangement of the blocking member 331, the flow path of the airflow becomes bent upward, which is beneficial to extend the flow path of the humid hot water vapor and make it fully contact with the blocking member 331, thereby promoting as much humid hot water vapor as possible to condense and liquefy and flow back to the inner cavity 11 of the dishwasher.
