Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of dishwashers, and in particular to a dishwasher. Background Art

[0002] The dishwasher includes an inner tank with a washing chamber defined therein and a ventilator arranged on the outer wall of the inner tank. The ventilator is used to connect the inside and outside of the washing chamber and to balance the air pressure inside and outside the washing chamber, thereby avoiding the formation of negative pressure in the washing chamber.

[0003] Currently, in order to improve the cleanliness of dishwashers and sterilize dishes, a sterilization device is installed in the washing chamber to sterilize the inside of the dishwasher and dishes by releasing ions. However, during the sterilization process, the ions will flow with the gas inside the dishwasher and be discharged into the external environment through the ventilation component, thereby weakening the sterilization effect inside the dishwasher and resulting in incomplete sterilization.

[0004] In view of this, this application is filed. Summary of the Invention

[0005] An embodiment of the present application provides a dishwasher, which includes a sterilization component and a ventilation component, and an air plate component and a driving component are arranged at the air outlet of the ventilation component. When sterilization is performed, the driving component is used to drive the air plate component to close the air inlet to form a closed space in the washing chamber, thereby reducing the ineffective discharge of ions generated by the sterilization component and improving the sterilization efficiency.

[0006] In the first aspect, an embodiment of the present application proposes a dishwasher, which includes a housing, a door and an inner tank. The housing is formed with a accommodating cavity and an opening connected to the accommodating cavity. The door is rotatably connected to the housing, and the door is used to open or close the opening. The inner tank is arranged in the accommodating cavity, and a washing cavity is defined inside the inner tank.

[0007] The dishwasher also includes a sterilization component and a ventilation component. The sterilization component is installed in the washing cavity and is used to generate ions. The ventilation component is used to connect the inside and outside of the washing cavity.

[0008] The ventilation component includes a shell, a wind plate component and a driving component. The shell is formed with a wind cavity and a first air inlet and a first air outlet connected to the wind cavity. The first air inlet is connected to the washing cavity, and the first air outlet is connected to the external environment.

[0009] The wind plate component is installed at the first air inlet; the driving component is connected to the wind plate component, and the driving component is used to drive the wind plate component to move to open or close the first air inlet.

[0010] The dishwasher includes a controller, which is connected to the sterilization component and the driving component. The controller is configured to control the driving component to move the air plate component to close the first air inlet before or during the operation of the sterilization component.

[0011] In this embodiment, a sterilization component is used to sterilize the inside of the dishwasher or the dishes, and before or during the sterilization process, the air plate component is driven to move by the driving component to form a closed space in the washing chamber, so as to increase the ion concentration in the washing chamber and improve the sterilization effect of the dishwasher.

[0012] In some embodiments, the outer shell includes a first shell and a second shell, a first air inlet is formed on the first shell, the first shell and the second shell are connected and form an air cavity, and a first air outlet is formed on the second shell; the air flow in the washing cavity enters the air cavity through the first air inlet, and then flows out of the washing cavity through the first air outlet.

[0013] In the above embodiment, the flow path of the airflow in the air cavity is precisely defined through the combined design of the first shell and the second shell. After the airflow in the washing cavity enters the air cavity through the first air inlet on the first shell, it can flow out from the first air outlet with a stable flow direction and flow rate under the guidance of the second shell.

[0014] This structured design avoids airflow turbulence and backflow in the cavity, making the ventilation process smoother and more efficient, reducing airflow resistance, helping to quickly discharge hot and humid gases inside the dishwasher, improving drying efficiency, and reducing energy loss caused by poor airflow.

[0015] In some embodiments, the wind plate component includes an adapter and an air guide. The adapter is installed on the wall of the first shell close to the second shell. The adapter is connected to the driving end of the driving component. The adapter can rotate along its own axis under the drive of the driving component.

[0016] The air guide is connected to the end face of the adapter away from the first air inlet. The connection between the air guide and the adapter is defined as the connection point. The air guide can rotate along the connection point. The driving component drives the adapter to rotate axially and then drives the air guide along the connection point to open or close the first air inlet.

[0017] The wind plate component adopts a combination design of an adapter and an air guide. The driving component drives the adapter to rotate along its own axis, and then drives the air guide to rotate around the connection point. This dual-rotation structure can achieve multi-angle and refined opening and closing control of the first air inlet.

[0018] Compared with the opening and closing components of a single structure, this design can accurately adjust the opening degree of the air inlet according to the needs of different working stages of the dishwasher. For example, in the strong exhaust stage after washing, the first air outlet can be fully opened to ensure that the hot and humid gas is quickly discharged; in the sterilization stage, the air outlet can be tightly closed to prevent ion leakage, creating a high-concentration ion sterilization environment for the washing chamber, greatly improving the intelligence and precision of the dishwasher's operation.

[0019] In some embodiments, a plurality of first guide columns are provided on the end face of the first shell close to the second shell, and the plurality of first guide columns are arranged at circumferential intervals along the first air inlet. A plurality of first limiting portions are correspondingly provided on the adapter. When the adapter rotates, the first guide columns can move in the first limiting portions.

[0020] By providing the first guide column and the first limiting portion, the adapter can be rotatably connected to the first shell, and the adapter is used as an intermediate piece for the rotation of the air guide piece, thereby improving the stability of the rotation of the air guide piece.

[0021] In some embodiments, the driving component includes a driving member and a driving rod. The driving member is installed on the end surface of the first shell close to the second shell. One end of the driving rod is connected to the driving end of the driving member, and the other end of the driving rod is connected to the adapter.

[0022] The two ends of the driving rod are directly connected to the driving part and the adapter respectively, which can more effectively transmit the power generated by the driving part to the adapter, reduce energy loss and vibration during the power transmission process, ensure that the adapter can accurately respond to the action instructions of the driving part, and realize the precise control of the air plate component over the first air outlet, thereby improving the working stability and reliability of the dishwasher ventilation assembly.

[0023] In some embodiments, a second limiting portion is provided on one side of the air guide member close to the adapter member. When the driving member drives the driving rod to move toward the driving member, the first guide column moves along the second limiting portion in a direction away from the connection point to drive the air guide member to rotate along the connection point and close the first air inlet.

[0024] The second stop on the air guide cooperates with the first guide post to provide a clear trajectory and limit reference for the air guide's rotation. During the sterilization process or during sterilization, when the drive component rotates the adapter, the first guide post moves along the second stop. This design ensures that the air guide rotates precisely along the preset path and angle, reliably closing the first air inlet.

[0025] In some embodiments, the second limiting portion is recessed along the axial direction of the adapter from a side of the air guide member close to the adapter to a side away from the adapter.

[0026] The second stopper is recessed away from the adapter, effectively utilizing the space on the side of the air guide closest to the adapter and preventing interference with surrounding components caused by conventional raised structures. This design makes the air plate more compact, reducing the space occupied within the narrow ventilation assembly, facilitating the rational layout of the dishwasher's internal structure and improving overall space utilization.

[0027] In some embodiments, the first limiting portion is provided through the adapter in a thickness direction, and the first guide post passes through the first limiting portion and is placed in the second limiting portion to limit the movement of the air guide.

[0028] By setting the first limiting portion through, the first guide column can pass through from one side of the adapter to the other side during the assembly process, without the need for complicated positioning and installation steps, thereby greatly reducing the difficulty of assembly.

[0029] In some embodiments, a second guide post is provided on the end surface of the first housing close to the second housing, and a third limiting portion and a fourth limiting portion are provided on the driving rod; the second guide post can reciprocate in the third limiting portion;

[0030] A third guide column is provided on the adapter, and the third guide column reciprocates in the fourth limiting portion; when the driving member drives the driving rod to move toward the driving member, the third limiting portion of the driving rod moves along the second guide column, and the third guide column moves along the fourth limiting portion toward the direction close to the third limiting portion to drive the adapter to rotate.

[0031] The second guide post and third limiter define the motion trajectory of the drive rod, improving the accuracy of the drive rod's movement. As the driver drives the air plate assembly to open and close the first air outlet, the second guide post effectively constrains the drive rod's motion, preventing it from deflecting or shaking during transmission. The third and fourth guide posts are also provided to enable rotation of the adapter within a limited space, ensuring the opening or closing of the first air inlet.

[0032] On the second aspect, an embodiment of the present application also proposes a dishwasher, which includes a box body, a door body and an inner tank. The box body is formed with a accommodating cavity and an opening connected to the accommodating cavity. The door body is rotatably connected to the box body, and the door body is used to open or close the opening. The inner tank is arranged in the accommodating cavity, and a washing cavity is defined inside the inner tank.

[0033] The dishwasher also includes a sterilization component and a ventilation component. The sterilization component is installed in the washing cavity and is used to generate ions. The ventilation component is arranged between the inner tank and the box body and is used to connect the inside and outside of the washing cavity.

[0034] The ventilation component includes a shell, a wind plate component and a driving component. The shell is formed with a wind cavity and a first air inlet and a first air outlet connected to the wind cavity. The first air inlet is connected to the washing cavity, and the first air outlet is connected to the external environment.

[0035] The wind plate component is installed at the first air outlet, and the wind plate component can be used to open or close the first air inlet; the driving component is connected to the wind plate component, and the driving component is used to drive the wind plate component to move to open or close the first air inlet.

[0036] This structure enables precise control of component movements during different operating phases. During the sterilization phase, closing the first air inlet reduces ion loss, enabling the sterilization component to achieve efficient sterilization with lower energy consumption. During the drying phase, the efficient ventilation component quickly removes moisture, shortening drying time and reducing the operating hours of the heating element, thereby reducing energy consumption.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0067] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0068] In the related art, in order to balance the air pressure inside and outside the dishwasher, the dishwasher includes a breather. However, in order to improve the cleaning effect of the dishwasher, the dishwasher currently includes a sterilization component. The sterilization component can be set to ultraviolet light or ion sterilization. When set to ion sterilization, the ions will flow with the gas inside the dishwasher and be discharged from the inside of the dishwasher through the breather, thereby reducing the sterilization effect of the dishwasher.

[0069] Based on the above, an embodiment of the present application proposes a dishwasher, which includes a ventilation component and a sterilization component, and is provided with a driving component and an air plate component. The driving component drives the air plate component to move to close the air inlet of the ventilation component during sterilization or in the sterilization process, thereby maintaining the closed conditions inside the dishwasher, thereby improving the sterilization efficiency.

[0070] The present application embodiment provides a dishwasher 100, referring to Figure 1 、 Figure 2 、 Figure 3 As shown, the dishwasher 100 includes a housing 10. The housing 10 is formed with a receiving cavity and an opening communicating with the receiving cavity. The housing 10 shell 41 can be set as one of a metal housing 10 shell 41 or a non-metal housing 10 shell 41.

[0071] The dishwasher 100 includes an inner container 20 disposed in a receiving cavity. The inner container 20 defines a washing cavity.

[0072] In some embodiments, the inner liner 20 can be made of steel. This material not only offers a long service life and high safety, but also provides enhanced drying and antibacterial properties. The inner liner 20 of the dishwasher 100 can be made of a thermally conductive material. The sidewalls and top of the inner liner 20 are covered with insulation panels for thermal insulation, while the inner sidewalls and top of the inner liner 20 are equipped with heating strips for heating. This configuration can improve the drying efficiency of the dishware in the dishwasher 100.

[0073] The dishwasher 100 further includes a door body that is rotatably mounted on the housing 10. The door body can be used to open or close an opening. The door body can prevent the spray liquid from splashing when the dishwasher 100 washes the dishes inside, thereby improving the neatness of the dishwasher 100 when in use.

[0074] In some embodiments, a sealing gasket may be provided on the door body to improve the sealing between the door body and the outer shell 41, so that when the dishwasher 100 is in use, even if there is a certain height of spray liquid in the cleaning chamber of the dishwasher 100, it will not overflow along the gap between the door body and the outer shell 41.

[0075] The dishwasher 100 includes a basket assembly disposed in a washing chamber for holding dishes.

[0076] The bowl basket assembly comprises at least a first rack, and the first rack is arranged in the washing cavity.

[0077] It is important to know that the number and location of shelves can be adjusted as needed.

[0078] The first rack includes a supporting net arranged horizontally and vertically, and bowl holders are arranged on the supporting net. When tableware is buckled on the bowl holders, the bowl holders contact the inner wall of the tableware to support the tableware, so that the tableware has stability when being rinsed by the spray liquid.

[0079] The dishwasher 100 further includes a spray pipe, which is disposed in the washing chamber and is used to connect spray liquid. One end of the spray pipe is connected to a liquid supply system.

[0080] The dishwasher 100 includes a spray assembly disposed within the washing chamber, between the basket assembly and the inner container 20. Tableware is placed or tilted in the basket assembly. The spray assembly is configured to spray liquid toward the basket assembly to clean the tableware in the basket assembly.

[0081] The liquid outlet of the liquid supply system is connected to the spray assembly and provides the spray assembly with spray liquid. The spray assembly rotates along the circumference of the spray assembly when the spray liquid is sprayed, so that the spray liquid covers the bowls on the bowl basket assembly and rinses the inner cavity and outer surface of the bowls, thereby achieving the effect of cleaning the tableware.

[0082] In some embodiments, the dishwasher 100 includes a sterilization component installed in the washing chamber and configured to generate ions.

[0083] In some embodiments, the sterilization component includes a plasma generating device, which uses dielectric barrier discharge technology to embed an insulating dielectric layer and an electrode plate on the top or side wall of the washing chamber. The distance between the electrode plates is controlled at 3-5 mm. A high-frequency high-voltage power supply (exemplarily, a frequency of 10-30 kHz and a voltage of 5-10 kV) is used to excite the air in the chamber to generate plasma, releasing highly active sterilizing ions such as hydroxyl radicals and oxygen ions.

[0084] In some embodiments, the sterilization component includes an electrolytic water ion generator, an electrolytic cell is arranged at the bottom of the washing chamber, and an anion and cation exchange membrane is built into the generator. By electrolyzing washing water containing trace salt, hypochlorite ions and chlorine are produced at the anode, and hydroxide ions are produced at the cathode. The ions are transported to various areas of the cavity through the guide tube.

[0085] It should be noted that those skilled in the art can also adjust the structure of the sterilization component according to actual needs.

[0086] In some embodiments, the dishwasher 100 includes a vent assembly 40. The vent assembly 40 is used to connect the inside and outside of the washing chamber. Figure 2 As shown, the ventilation assembly 40 is installed between the inner liner 20 and the box body 10.

[0087] In some embodiments, reference Figure 4 、 Figure 5 、 Figure 6As shown, the ventilation assembly 40 includes a housing 41. The housing 41 is formed with an air cavity and a first air inlet 413 and a first air outlet 414 communicating with the air cavity. The first air inlet 413 communicates with the washing cavity, and the first air outlet 414 communicates with the external environment.

[0088] Reference Figure 6 As shown, the ventilation assembly 40 includes a wind plate component 43. The wind plate component 43 is installed at the first air inlet 413, and the wind plate component 43 can be used to open or close the first air inlet 413.

[0089] The ventilation assembly 40 includes a driving component 42 . The driving component 42 is connected to the air plate component 43 , and the driving component 42 is used to drive the air plate component 43 to move so as to open or close the first air inlet 413 .

[0090] The dishwasher 100 includes a controller connected to the sterilization assembly and the drive unit 42. The controller can control the working state and working process of the dishwasher 100. In this embodiment, the sterilization process of the dishwasher 100 and the operation of some components after sterilization are mainly involved.

[0091] The controller is configured to control the driving component 42 to drive the wind plate component 43 to move before or during the operation of the sterilization component to close the first air inlet 413. The structural diagram of the closed state of the first air inlet 413 is shown in FIG. Figure 10 shown.

[0092] In this embodiment, a sterilization component is used to sterilize the interior of the dishwasher 100 or the dishes, and before or during the sterilization process, the driving component 42 drives the wind plate component 43 to move and close the first air inlet 413, so that a relatively closed space can be formed in the washing chamber. This effectively prevents the ions (such as hydroxyl radicals, silver ions, etc.) generated by the sterilization component from leaking to the external environment through the ventilation component 40, ensuring that high-concentration ions in the washing chamber fully act on the interior of the dishwasher 100 and the surface of the dishes, reducing ion loss and extending the action time of ions in the chamber, thereby improving the sterilization efficiency and ensuring the cleanliness and hygiene of the tableware and the safety of users.

[0093] The air plate component 43 is mounted at the first air inlet 413 and cooperates with the drive component 42 to open and close. When closed, it fits tightly against the housing 41, forming a well-sealed structure. This design effectively prevents external air, dust, and foreign matter from entering the washing chamber, preventing interference with the sterilization process or secondary contamination.

[0094] In some embodiments, after the sterilization is completed, the control driving component 42 drives the wind plate component 43 to move to open the first air inlet 413. The structural diagram of the first air inlet 413 in the open state is shown in FIG. Figure 6 shown.

[0095] In this embodiment, after sterilization is complete, the first air inlet 413 is opened to ensure that the hot and humid air in the washing chamber can be quickly discharged. This, combined with the drying function, accelerates the drying of dishes, shortens the drying time, and further reduces energy consumption during the drying process. Over long-term use, this can effectively reduce the user's electricity costs and improve the energy efficiency of the dishwasher 100.

[0096] In some embodiments, the controller is configured such that, when the dishwasher performs a washing program, the first air inlet 413 of the ventilation component 40 is in an open state to balance the air pressure.

[0097] In some embodiments, the dishwasher 100 may be configured as follows: Figure 4 、 Figure 5 As shown, the housing 41 includes a first shell 411. A first air inlet 413 is formed on the first shell 411. Figure 2 As shown, the first shell 411 is connected to the outer wall of the inner tank 20 so that the first air inlet 413 is connected to the washing chamber.

[0098] The housing 41 includes a second shell 412 , a first shell 411 and a first air inlet 413 . The first shell 411 and the second shell 412 are connected to form an air cavity, and a first air outlet 414 is formed on the second shell 412 .

[0099] The airflow in the washing chamber enters the air chamber through the first air inlet 413 and then flows out of the washing chamber through the first air outlet 414 .

[0100] It should be noted that the first air outlet 414 can be connected to the space between the inner tank 20 and the box body 10, and the air flow in the air cavity is discharged from the first air outlet 414 to between the inner tank 20 and the box body 10, and then discharged to the outside of the dishwasher 100 through the holes on the box body 10.

[0101] Of course, in some other embodiments, an air duct component may be provided at the first air outlet 414 to assist in discharging the airflow in the washing cavity out of the dishwasher 100 .

[0102] In the above embodiment, the combined design of the first shell 411 and the second shell 412 accurately defines the flow path of the airflow in the air cavity. After the airflow in the washing cavity enters the air cavity through the first air inlet 413 on the first shell 411, it can flow out from the first air outlet 414 with a stable flow direction and flow rate under the guidance of the second shell 412.

[0103] This structured design avoids airflow turbulence and backflow in the cavity, making the ventilation process smoother and more efficient, reducing airflow resistance, helping to quickly discharge hot and humid air inside the dishwasher 100, improving drying efficiency, and reducing energy loss caused by poor airflow.

[0104] In some embodiments, a positioning hole is provided on the first shell 411, and a positioning column is provided on the second shell 412. The positioning hole and the positioning column are connected in a coordinated manner. The first shell 411 and the second shell 412 are welded by hot plate welding or other processes to form a molten sealing state at their joints, thereby ensuring the air tightness of the ventilation assembly 40.

[0105] In some embodiments, a sealing ring is provided on a side of the first air inlet 413 away from the second shell 412 to connect the first air inlet 413 with the washing chamber.

[0106] In some embodiments, an exhaust port is provided on the outer wall of the inner container 20. The first air inlet 413 is connected to the exhaust port to guide the air in the washing chamber into the air chamber of the ventilation assembly 40.

[0107] In some embodiments, reference Figure 6 、 Figure 11 As shown, the wind plate component 43 includes an adapter 431. The adapter 431 is installed on the wall of the first shell 411 close to the second shell 412, and is connected to the driving end of the driving component 42. The adapter 431 can rotate along its own axis under the drive of the driving component 42.

[0108] The wind plate component 43 includes an air guide 432. The air guide 432 is connected to the end face of the adapter 431 away from the first air inlet 413. The connection point between the air guide 432 and the adapter 431 is defined as a connection point 4313. The air guide 432 can rotate along the connection point 4313.

[0109] The driving component 42 drives the adapter 431 to rotate axially and then drives the air guide 432 along the connection point 4313 to open or close the first air inlet 413 .

[0110] In the above embodiment, a dual-stage transmission structure is employed, in which the axial rotation of the adapter 431 drives the air guide 432 to rotate about the connection point 4313, forming a mechanical transmission system similar to a connecting rod and a rocker. The power of the drive component 42 is transmitted to the air guide 432 via the axial rotation of the adapter 431. This dual-rotation structure enables multi-angle and refined opening and closing control of the first air inlet 413, reducing backlash and offset during the transmission process, achieving rapid and precise opening and closing response, and improving the dishwasher 100's ability to control the internal airflow.

[0111] Compared with the opening and closing components of a single structure, this design can accurately adjust the opening degree of the air inlet according to the needs of different working stages of the dishwasher 100. For example, in the strong exhaust stage after washing, the first air outlet 414 can be fully opened to ensure that the hot and humid gas is quickly discharged; in the sterilization stage, the air outlet can be tightly closed to prevent ion leakage, creating a high-concentration ion sterilization environment for the washing chamber, greatly improving the intelligence and precision of the dishwasher 100.

[0112] In some embodiments, the number of the air guide members 432 is five. Of course, the number of the air guide members 432 can also be four, six, seven, eight, etc., as long as the air guide members 432 can jointly block the first air inlet 413 .

[0113] When the driving component 42 drives the adapter 431 to rotate, the plurality of air guides 432 rotate inwardly about the center of the first air inlet 413, closing the first inlet and outlet 413. When the driving component 42 drives the adapter 431 to rotate in the opposite direction, the plurality of air guides 432 rotate outwardly about the center of the first air inlet 413, opening the first inlet and outlet 413.

[0114] In some embodiments, reference Figure 6 As shown, the driving component 42 includes a driving member 421. The driving member 421 is installed on the end surface of the first housing 411 close to the second housing 412. The driving member 421 provides power for the adapter 431 and the air guide 432 to rotate.

[0115] The driving component 42 includes a driving rod 422 , one end of the driving rod 422 is connected to the driving end of the driving member 421 , and the other end of the driving rod 422 is connected to the adapter 431 .

[0116] The two ends of the driving rod 422 are directly connected to the driving member 421 and the adapter 431 respectively, which can more effectively transmit the power generated by the driving member 421 to the adapter 431, reduce energy loss and vibration during the power transmission process, and ensure that the adapter 431 can accurately respond to the action instructions of the driving member 421, thereby realizing the precise control of the wind plate component 43 over the first air outlet 414, and improving the working stability and reliability of the ventilation assembly 40 of the dishwasher 100.

[0117] In some embodiments, the adapter 431 is provided with a connector, which protrudes from one end surface close to the air guide. The air guide 432 is provided with a through hole, and the air guide 432 is installed on the connector through the through hole, and the air guide 432 can rotate along the connector.

[0118] In some embodiments, a through hole may be provided on the adapter 431 , and a connecting piece may be provided on the air guide 432 . The connecting piece may be inserted into the through hole and allowed to rotate relative to the through hole.

[0119] Reference Figure 11 As shown, a connecting portion 418 is provided on the end surface of the first shell 411 close to the second shell 412 . The connecting portion 418 is provided semi-surrounding the driving member 421 to define the installation position of the driving member 421 .

[0120] In some embodiments, reference Figure 11 、 Figure 9 As shown, a plurality of first guide posts 415 are provided on the end surface of the first shell 411 close to the second shell 412 , and the plurality of first guide posts 415 are circumferentially spaced apart along the first air inlet 413 .

[0121] In order to achieve a stable rotational connection between the adapter 431 and the first shell 411 , a plurality of first limiting portions 4311 are correspondingly provided on the adapter 431 . When the adapter 431 rotates, the first guide post 415 can move in the first limiting portions 4311 .

[0122] By providing the first guide column 415 and the first limiting portion 4311 , the adapter 431 can be rotatably connected to the first shell 411 , and the adapter 431 can be used as an intermediate piece for the rotation of the air guide 432 , thereby improving the rotation stability of the air guide 432 .

[0123] In some embodiments, the first limiting portion 4311 is provided through the thickness direction of the adapter 431 , and the first guide column 415 passes through the first limiting portion 4311 and is placed in the second limiting portion 4321 to limit the movement of the air guide 432 .

[0124] By setting the first limiting portion 4311 through, the first guide column 415 can pass through from one side of the adapter 431 to the other side during the assembly process, without the need for complicated positioning and installation steps, greatly reducing the difficulty of assembly.

[0125] In some embodiments, reference Figure 14 As shown, the first guide column 415 is provided with a step structure, and the cross section of the step structure near the first air inlet 413 is larger than the cross section of the side away from the first air inlet 413. The side with the slightly larger step structure is defined as the first part, and the side with the slightly smaller step structure is defined as the second part.

[0126] The first limiting portion is sleeved on the first portion, and the second limiting portion is installed on the second portion.

[0127] Reference Figure 11 、 Figure 14 As shown, a limiting slot 419 is further provided on the first housing 411 to help limit the rotation range of the adapter 431. The limiting slot 419 and the first guide post 415 together limit the rotation of the adapter 431 within a fixed angle.

[0128] Reference Figure 7As shown, when the first air inlet 413 switches from the open state to the closed state, the adapter 431 rotates along its own axis in the opposite direction of the X direction, and when the first air inlet 413 switches from the closed state to the open state, the adapter 431 rotates along its own axis in the X direction.

[0129] In some embodiments, the first guide post 415 is configured as a cylinder protruding from the end surface of the first housing 411. Figure 11 As shown, the first guide posts 415 are provided in five numbers. It should be noted that the first guide posts 415 may also be provided in four, six, seven, etc. Those skilled in the art may set the number of the first guide posts 415 as needed to meet the requirement of limiting the rotation of the adapter 431.

[0130] In some embodiments, reference Figure 8 、 Figure 9 As shown, a second limiting portion 4321 is provided on the side of the air guide member 432 close to the adapter 431. When the driving member 421 drives the driving rod 422 to move toward the driving member 421, the first guide column 415 moves along the second limiting portion 4321 in a direction away from the connection point 4313 to drive the air guide member 432 to rotate along the connection point 4313 and close the first air inlet 413.

[0131] The second stopper 4321 on the air guide 432 cooperates with the first guide post 415 to provide a clear motion trajectory and limit reference for the rotation of the air guide 432. During the sterilization process or at the time of sterilization, when the drive component 42 drives the adapter 431 to rotate, the first guide post 415 moves along the second stopper 4321. This design ensures that the air guide 432 can rotate precisely along the preset path and angle, achieving reliable closure of the first air inlet 413.

[0132] In some embodiments, the second limiting portion 4321 is recessed along the axial direction of the adapter 431 from a side of the air guide 432 close to the adapter 431 to a side away from the adapter 431 .

[0133] The second stopper 4321 is recessed away from the adapter 431, effectively utilizing the space on the side of the air guide 432 near the adapter 431 and preventing interference with surrounding components caused by conventional raised structures. This design makes the air plate 43 more compact, reducing the space occupied within the narrow ventilation assembly 40. This facilitates the rational layout of the internal structure of the dishwasher 100 and improves overall space utilization.

[0134] Reference Figure 7As shown, when the first air inlet 413 needs to be closed during or before sterilization, the driving member 421 drives the driving rod 422 to move in the direction indicated by the Y axis, and the first guide column 415 moves along the first limiting portion 4311. At this time, the adapter 431 rotates clockwise along the axial direction under the drive of the driving member 42 ( Figure 7 4313 is fixed, and the first guide column 415 moves along the second limiting portion 4321 to the side away from the connection point 4313, so that the air guide 432 moves counterclockwise around the connection point 4313. The plurality of air guides 432 rotate together to close the first air inlet 413. When the first air inlet 413 is in the closed state, the assembly relationship between the driving member 421, the driving rod 422, the adapter 431 and the air guide 432 is shown in FIG. Figure 12 、 Figure 13 shown.

[0135] When the first air inlet 413 needs to be opened, the driving member 421 drives the driving rod 422 to move in the opposite direction of the Y axis, and the first guide column 415 moves along the first limit portion 4311. At this time, the rotating member rotates counterclockwise along the axial direction under the drive of the driving rod 422 ( Figure 7 At this time, the connection point 4313 between the air guide member 432 and the adapter 431 is fixed, and the first guide column 415 moves along the second limiting portion 4321 toward the side close to the connection point 4313, so that the air guide member 432 rotates clockwise around the connection point 4313, and multiple air guide members 432 rotate together to realize the opening of the first air inlet 413.

[0136] Reference Figure 7 As shown, a flow guide 417 is provided on the end surface of the first shell 411 close to the second shell 412 , and the flow guide 417 is provided as a plate-shaped structure protruding from the end surface.

[0137] The guide member 417 is configured to be in an arc shape, which allows the airflow to flow along the surface of the guide member 417, thereby reducing wind resistance, increasing ventilation volume per unit time, and allowing the interior of the dishwasher 100 to return to a suitable temperature and humidity environment more quickly.

[0138] Reference Figure 7 As shown, the guide members 417 include a plurality of staggered arrangements to accurately guide the airflow within the ventilation assembly 40 to prevent the airflow from forming turbulent vortices or dead corners within the ventilation assembly 40 .

[0139] During the drying stage of the dishwasher 100, the guide member 417 can guide the hot and humid gas in the washing chamber to enter the air chamber through the first air inlet 413 in a smoother path and be discharged from the first air outlet 414, thereby reducing air flow resistance, accelerating the moisture discharge speed, and shortening the drying time of the dishes.

[0140] Reference Figure 6 As shown, a notch 4223 is provided on the side of the drive rod 422 adjacent to the driver 421. This notch 4223 is configured as a semicircular or U-shaped groove, allowing the connection between the drive rod 422 and the driver 421 to be non-rigid. When the driver 421 is in motion, the notch 4223 provides a certain amount of movement for the drive rod 422, compensating for assembly errors or slight deviations in the direction of motion, and avoiding stress concentration caused by rigid constraints.

[0141] In some embodiments, reference Figure 11 As shown, a second guide column 416 is provided on the end surface of the first shell close to the second shell. The second guide column 416 is configured as a cylinder protruding from the end surface of the first shell 411 .

[0142] The driving rod 422 is provided with a third limiting portion 4221. The second guide column 416 can do reciprocating motion in the third limiting portion 4221.

[0143] Reference Figure 8 As shown, the third limiting portion 4221 is configured as an elongated through hole, and the stability of the movement of the driving rod 422 is limited by the provision of the third limiting portion 4221 .

[0144] The driving rod 422 is further provided with a fourth limiting portion 4222. A certain angle is formed between the straight line where the fourth limiting portion 4222 is located and the straight line where the third limiting portion 4221 is located.

[0145] In some embodiments, the fourth limiting portion 4222 is configured as an elongated through hole that passes through the pair of limiting portions 4222. The fourth limiting portion 4222 is used to assist the rotation of the adapter 431, ensuring that the adapter 431 can rotate within a limited space.

[0146] A third guide post 4312 is provided on the adapter 431 , and the third guide post 4312 reciprocates in the fourth limiting portion 4222 .

[0147] When the driving member 421 drives the driving rod 422 to move toward the driving member 421, the third limiting portion 4221 of the driving rod 422 moves along the second guide column 416, and the third guide column 4312 moves along the fourth limiting portion 4222 toward the direction close to the third limiting portion 4221, thereby driving the adapter 431 to rotate.

[0148] The second guide post 416 and the third stopper 4221 define the motion trajectory of the drive rod 422, improving the accuracy of the drive rod 422's movement. As the driver 421 drives the air plate component 43 to open and close the first air outlet 414, the second guide post 416 effectively constrains the drive rod 422's motion, preventing it from deflecting or shaking during transmission. The third and fourth guide posts 4312 are also provided to enable the adapter 431 to rotate within a limited space, ensuring the opening or closing of the first air inlet 413.

[0149] In this embodiment, the dishwasher 100 includes a sterilization component and a ventilation component 40. The sterilization component is installed in the washing chamber. The sterilization component is used to generate ions. The ventilation component 40 is used to connect the inside and outside of the washing chamber. The ventilation component 40 includes a shell 41, a wind plate component 43 and a driving component 42. The shell 41 is formed with a wind chamber and a first air inlet 413 and a first air outlet 414 connected to the wind chamber. The first air inlet 413 is connected to the washing chamber, and the first air outlet 414 is connected to the external environment. The wind plate component 43 is installed in the first At the air inlet 413; the driving component 42 is used to drive the air plate component 43 to move to open or close the first air outlet 414. The controller is configured to control the driving component 42 to drive the air plate component 43 to move and close the first air inlet 413 before controlling the operation of the sterilization component or during the operation of the sterilization component. Before or during sterilization, the present application drives the air plate component 43 to move by the driving component 42 to form a closed space in the washing chamber, so as to facilitate the increase of ion concentration in the washing chamber and improve the sterilization effect of the dishwasher 100.
