Description

Technical Field

[0001] This utility model relates to the technical field of tableware cleaning equipment, and in particular to a cleaning device. Background Technology

[0002] A dishwasher is a device used to automatically clean dishes. Because washing dishes with a dishwasher greatly reduces tedious manual labor, is easy to operate, and has a high degree of automation, it has become increasingly popular among consumers.

[0003] Existing dishwashers typically include at least one spray system and a dish rack for placing dishes to be washed. During washing, the user places the dishes in the dish rack, starts the dishwasher, and the spray system sprays water to rinse the dishes in the dish rack.

[0004] The current problem with dishwashers on the market is the long washing time, especially when washing a large number of dishes at once, but only some of them have stubborn stains. If you want to clean these heavily soiled dishes at the same time, the washing time is usually more than two hours; and some dishwashers even if the washing time reaches more than two hours, it is difficult to achieve the desired cleaning effect on these heavily soiled dishes.

[0005] Furthermore, when washing a small number of dishes at a time, even using the quick wash mode of an existing dishwasher results in a relatively long washing time (generally around 50 minutes). Especially when these few dishes have stubborn stains, even a 50-minute wash will not achieve the desired cleaning effect; moreover, when washing a small number of dishes, all the spray arms will work to spray liquid throughout the entire dishwasher drum, wasting water and electricity.

[0006] Current dishwashers generally suffer from long washing times and high electricity and water consumption. Especially when the dishes contain a small amount of heavily soiled items, even significantly extended washing times may not achieve the desired cleaning results. Overall, there is considerable room for improvement in existing dishwashers.

[0007] Therefore, it is necessary to propose a cleaning device to solve at least one of the above problems. Utility Model Content

[0036] The technical solution of this utility model has the following significant beneficial effects:

[0037] The cleaning device provided in this application embodiment includes a drive component in a predetermined area of ​​the inner liner that can rotate tableware and / or cookware, and a second spray component that can spray liquid onto the tableware and / or cookware placed in the predetermined area. In use, the second spray component provides concentrated direct spray cleaning of the tableware and / or cookware placed in the predetermined area, while the drive component simultaneously rotates the tableware and / or cookware in the predetermined area for rotational cleaning. This combination of direct spray cleaning and rotational cleaning achieves comprehensive, thorough cleaning of the tableware and / or cookware within the predetermined area, while also improving cleaning efficiency and energy saving.

[0038] Specifically, when rotary cleaning is combined with direct-jet spray cleaning, the direct-jet spray liquid is directly applied to the surface of tableware and / or cookware through pressurized water flow. It is particularly effective at rinsing stubborn stains adhering to the inner surfaces of tableware and / or cookware, such as custard on the bottom of bowls or burnt rice on the bottom of pots. This solves the problem that with rotary spray alone, certain areas of tableware and / or cookware cannot be directly rinsed by the liquid flow, resulting in areas that are difficult to clean thoroughly.

[0039] When rotary cleaning is combined with direct spray cleaning, during the direct spray cleaning process, the tableware and / or kitchenware can be driven to rotate by the drive component, which not only continuously changes the contact position with the liquid flow, but also utilizes the rotation of the tableware and / or kitchenware to discharge the dirt washed off by the liquid flow downwards under the action of gravity, thereby also helping to improve cleaning efficiency.

[0040] When rotary washing is combined with direct spraying, the rotating tableware and / or cookware undergo relative motion with the sprayed liquid, creating a mechanical effect similar to scrubbing. This enhances the removal of stubborn stains, thereby improving cleaning efficiency, shortening cleaning time, and saving water and electricity. In particular, when the angle between the liquid stream and the surface of the tableware and / or cookware is acute, it's equivalent to the liquid stream scraping stubborn stains circumferentially at a certain angle, further enhancing the removal of stubborn stains.

[0085] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0086] This invention provides a cleaning device that effectively improves the cleaning ability of the device for tableware and / or kitchenware with stubborn stains. It can also independently clean a small number of tableware and / or kitchenware placed in a local area, significantly shortening the cleaning time, saving water and electricity, and improving the cleaning effect.

[0087] Please refer to the following for comprehensive information. Figures 1 to 17This application specification provides a cleaning device, which may include: an inner liner 1 for holding tableware and / or kitchen utensils; a first spray assembly disposed in the inner liner 1 for spraying liquid into the inner liner 1; a drive assembly 2 disposed in a predetermined area of ​​the inner liner 1, the drive assembly 2 being capable of rotating the tableware and / or kitchen utensils placed in the predetermined area; and a second spray assembly 4 disposed in the inner liner 1, the second spray assembly 4 being capable of spraying liquid onto the tableware and / or kitchen utensils placed in the predetermined area.

[0088] In this specification, the cleaning device can specifically be a dishwasher, used to clean tableware, kitchen utensils, and other items. Tableware may include bowls, plates, dishes, chopsticks, etc., and kitchen utensils may include pots, pans, etc. In addition, the cleaning device can also be used to clean items of the same or similar size and structure as tableware and kitchen utensils. In the embodiments described in this specification, a dishwasher is primarily used as an example. For tableware and / or kitchen utensils, bowls are primarily used as an example. Other similar application scenarios can be found in this specification, and will not be detailed here.

[0089] In the embodiments of the application, the cleaning device may include: an inner tank 1, a first spray assembly, a drive assembly 2, and a second spray assembly 4, etc.

[0090] like Figure 1 and Figure 2 As shown, the inner liner 1 can specifically have a hollow box structure. The hollow portion of the inner liner 1 can be used to accommodate tableware and / or kitchen utensils. Specifically, at least one sliding dish rack can be provided in the inner liner 1, through which the tableware and / or kitchen utensils can be placed in the inner liner 1. In addition, the hollow portion of the inner liner 1 can also accommodate a first spray assembly, a second spray assembly 4, and a drive assembly 2, etc.

[0091] The first spray assembly is disposed in the inner liner 1 and is used to spray liquid into the inner liner 1 for spraying and cleaning tableware and / or kitchen utensils.

[0092] Specifically, the first spray assembly may include at least one spray arm. Of course, the first spray assembly may also include other structures or other forms, and this application does not impose specific limitations here. In this embodiment, the first spray assembly is mainly illustrated in the form of a spray arm.

[0093] The number of spray arms can vary depending on the number of layers of the baskets provided in the inner liner 1. As the number of basket layers increases, the number of spray arms can also be increased accordingly. For example, the first spray assembly may include one or a combination of a top spray arm 33, an upper spray arm 32, and a lower spray arm 31.

[0094] Overall, at least one spray arm can be provided for each dish basket, and the liquid sprayed by each spray arm can cover the corresponding dish basket. For example, when there is one dish basket in the inner liner 1, the number of spray arms can be one or two; when there are two dish baskets in the inner liner 1, the number of spray arms can be two, three or four, etc.

[0095] The first spray assembly can be connected to a liquid supply system. When the cleaning device is operating, the liquid supply system is connected to the first spray assembly to provide cleaning spray liquid to tableware and / or kitchenware. The liquid supply system can be a system capable of providing spray liquid to the first spray assembly. Specifically, the liquid supply system can be a tap water source to provide room temperature water to the first spray assembly; the liquid supply system can also be equipped with a heating device to heat the room temperature water, thereby providing hot water to the first spray assembly; furthermore, the liquid supply system can also include a container capable of holding detergent with degreasing properties, thereby providing detergent to the first spray assembly, or providing a mixture of detergent and water to the first spray assembly. In addition, the liquid supply system of the cleaning device can be superimposed with other functional modules, such as a water softening module, to provide water softened by the water softening module to the first spray assembly.

[0096] The first spray assembly can be in a rotating state during operation to spray tableware and kitchenware, or it can be positioned at one or more designated locations to spray tableware and kitchenware in a directional manner; or it can be a combination of the above-mentioned spray states. When the first spray assembly is in a rotating state while spraying and cleaning the tableware and / or kitchenware, its rotational power can be hydraulic, electric, or a combination of both, or it can also be combined with other driving methods.

[0097] like Figure 3 and Figure 4 As shown, the drive assembly 2 is disposed in a predetermined area of ​​the inner liner 1, and the drive assembly 2 is capable of rotating the tableware and / or kitchen utensils placed in the predetermined area. Specifically, the drive assembly 2 may include a drive part 20 and a transmission part, the drive part 20 driving the transmission part to rotate, and when tableware and / or kitchen utensils are disposed on the transmission part, the transmission part is used to drive the tableware and / or kitchen utensils to rotate.

[0098] The drive unit 20 can be an electric drive structure, a hydraulic drive structure, a combination of both, or a mechanism formed by other power drive methods or a combination of multiple power drive methods. In this embodiment, the drive unit 20 is mainly described as a hydraulic drive structure; other forms can be described with reference to this form, and will not be described in detail here.

[0099] In one embodiment, the drive unit 20 may include a flow channel and a drive member, the flow channel having a fluid inlet and a fluid outlet, the fluid inlet for receiving fluid, and the fluid outlet for discharging the fluid to the drive member to rotate it.

[0100] The flow channel can be any form capable of guiding fluid to the drive member, and this application does not impose specific limitations here. For example, the drive unit 20 is provided with a housing, and the flow channel can be an internal flow path disposed within the housing. The housing is also provided with a fluid outlet. The fluid discharged from the fluid outlet can flow into a designated area, such as a water cup, for subsequent recycling. When the drive unit 20 includes a housing, the drive member is disposed within the housing. The drive member can be in a form capable of rotation under the action of fluid; for example, the drive member can include at least one impeller; or, the drive member can also include at least one impeller and several gears; or, the drive member can be in other forms, and this application does not impose specific limitations here.

[0101] Of course, the specific form of the drive unit 20 is not limited to the examples above, and this application does not make specific limitations here. When tableware and / or kitchen utensils are provided on the transmission unit, the drive unit 20 drives the transmission unit to rotate, and the transmission unit can drive the tableware and / or kitchen utensils to rotate.

[0102] In one embodiment, the transmission unit may include a first transmission member, the first transmission member including a rotating shaft that rotates with the driving member, the rotating shaft being detachably connected to the driving member or integrally formed therefrom.

[0103] In this embodiment, the transmission part may include a first transmission member, which may be in the form of a rotating shaft. Of course, the first transmission member may also be in other forms. In this embodiment, the first transmission member is mainly described as being in the form of a rotating shaft. Other forms can be described with reference to this form. This application will not elaborate on them one by one here.

[0104] The rotating shaft extends longitudinally and has a first end and a second end. At least one end (the first end) of the rotating shaft can be integrally formed with the driving component, or at least one end (the first end) of the rotating shaft can be detachably connected to the driving component, thereby ensuring the transmission of the torque output by the driving component. The detachable connection can be a snap-fit ​​or other form that facilitates disassembly, allowing the rotating shaft to be individually removed for maintenance or replacement.

[0105] When the first end of the shaft is integrally formed with or detachably connected to the drive component, the other end of the shaft (e.g., the second end) can be installed and positioned by means of a rotatable connection (e.g., rotatably connected to a bowl basket), thereby ensuring that the shaft can rotate smoothly.

[0106] Taking the impeller as an example of the driving component, the impeller and the rotating shaft are detachably connected or integrally formed. When the impeller and the rotating shaft are detachably connected, a transmission structure can be formed between them. This transmission structure can specifically be a keyway and key mating structure to ensure that the impeller reliably transmits torque to the rotating shaft. Of course, it can also be other forms of transmission structure, which are not specifically limited here.

[0107] In this embodiment, the second spraying assembly 4 is capable of spraying liquid onto tableware and / or kitchen utensils placed in the predetermined area.

[0108] The designated area may include a portion of a dish rack. This designated area can be used to place tableware and / or cookware with stubborn stains, and can be a heavily soiled cleaning area. The definition of the designated area can vary depending on different usage modes of the cleaning device. For example, the designated area can also be used to centrally place a small number of tableware and / or cookware requiring cleaning, while other areas of the inner liner 1 may not hold tableware and / or cookware; in this case, the designated area can be a concentrated cleaning area for a small number of items.

[0109] To ensure that the liquid sprayed by the second spray assembly 4 can be directly sprayed onto the tableware and / or kitchen utensils, and to prevent the liquid from passing directly through the gap between two pieces of tableware and / or kitchen utensils (taking a bowl as an example) without contacting the surface of the bowl, such as... Figure 6 and Figure 7 As shown, the angle α between at least one direction of the liquid sprayed by the second spray assembly 4 and the opening 60 of at least one piece of tableware and / or kitchenware (taking a bowl as an example) placed at a predetermined position on the transmission part ranges from 0 ≤ α < 90 degrees or 90 < α ≤ 180 degrees. That is, the direction of the liquid sprayed by the second spray assembly 4 is not perpendicular to the opening 60 of the tableware and / or kitchenware.

[0110] In use, the second spray assembly 4 provides concentrated direct spray cleaning of tableware and / or kitchenware placed in the predetermined area, while the drive assembly 2 rotates the tableware and / or kitchenware in the predetermined area for rotary cleaning. This combination of direct spray cleaning and rotary cleaning achieves comprehensive, thorough cleaning of tableware and / or kitchenware within the predetermined area, while improving cleaning efficiency and energy saving.

[0111] Specifically, when rotary cleaning is combined with direct-jet spray cleaning, the direct-jet spray liquid is directly applied to the surface of tableware and / or cookware through pressurized water flow. It is particularly effective at rinsing stubborn stains adhering to the inner surfaces of tableware and / or cookware, such as custard on the bottom of bowls or burnt rice on the bottom of pots. This solves the problem that with rotary spray alone, certain areas of tableware and / or cookware cannot be directly rinsed by the liquid flow, resulting in areas that are difficult to clean thoroughly.

[0112] When rotary cleaning is combined with direct spray cleaning, during the direct spray cleaning process, the tableware and / or kitchenware can be driven to rotate by the drive unit 20, which not only continuously changes the contact position with the liquid flow, but also uses the rotation of the tableware and / or kitchenware to discharge the dirt washed off by the liquid flow downwards under the action of gravity, thereby also helping to improve cleaning efficiency.

[0113] When rotary washing is combined with direct spraying, the rotating tableware and / or cookware undergo relative motion with the sprayed liquid, creating a mechanical effect similar to scrubbing. This enhances the removal of stubborn stains, thereby improving cleaning efficiency, shortening cleaning time, and saving water and electricity. In particular, when the angle between the liquid stream and the surface of the tableware and / or cookware is acute, it's equivalent to the liquid stream scraping stubborn stains circumferentially at a certain angle, further enhancing the removal of stubborn stains.

[0114] In one embodiment, the first transmission component may include a first rotating shaft 21 that rotates with the driving component and a second rotating shaft 22 that rotates with the driving component, the first rotating shaft 21 and the second rotating shaft 22 being arranged in parallel; the spray path of the second spray assembly 4 is located above the first rotating shaft 21 and the second rotating shaft 22.

[0115] In this embodiment, the first transmission component includes a first rotating shaft 21 and a second rotating shaft 22 that rotate with the driving component. Either the first rotating shaft 21 or the second rotating shaft 22 can be directly driven by the driving component to rotate. However, this embodiment does not exclude the possibility that one of the first rotating shaft 21 or the second rotating shaft 22 can be directly driven by the driving component, while the other can be indirectly driven by the driving component. The following embodiments primarily illustrate the example where both the first rotating shaft 21 and the second rotating shaft 22 directly rotate with the driving component.

[0116] The first rotating shaft 21 and the second rotating shaft 22 can be arranged in parallel. Furthermore, the distance between the first rotating shaft 21 and the second rotating shaft 22 is the same along the extension direction of the rotating shafts. Of course, in this embodiment, it is not excluded that the first rotating shaft 21 and the second rotating shaft 22 may not be parallel.

[0117] In use, the tableware and / or kitchen utensils are basically located above the first rotating shaft 21 and the second rotating shaft 22. In order for the spray path of the second spray assembly 4 to cover the surface of the tableware and / or kitchen utensils, the spray path of the second spray assembly 4 is located above the first rotating shaft 21 and the second rotating shaft 22.

[0118] In one embodiment, the first rotating shaft 21 and the second rotating shaft 22 are on the same predetermined plane, and the orthogonal projection of the spray path of the second spray assembly 4 on the predetermined plane is not perpendicular to the first rotating shaft 21 or the second rotating shaft 22.

[0119] In this embodiment, the first rotating shaft 21 has a first axis, and the second rotating shaft 22 has a second axis, which are parallel to each other. The predetermined plane is a plane passing through the first and second axes. When the orthogonal projection of the spray path of the second spray assembly 4 onto the predetermined plane is not perpendicular to the first rotating shaft 21 or the second rotating shaft 22, it can prevent the spray path of the second spray assembly 4 from being located in the interval area between two adjacent pieces of tableware and / or kitchenware without contacting the tableware and / or kitchenware. That is, it can be ensured that the spray path of the second spray assembly can reliably spray onto the surface of the tableware and / or kitchenware.

[0120] In one embodiment, the transmission part further includes a second transmission member 23 that rotates with the first transmission member. The second transmission member 23 is sleeved on the circumference of the first transmission member or the second transmission member 23 is integrally formed with the first transmission member. There are multiple second transmission members 23, which are distributed at intervals along the axial direction of the first transmission member. The second transmission members 23 can define the opening position of the tableware and / or kitchenware.

[0121] In this embodiment, the transmission unit may further include a second transmission member 23, which is disposed on the first transmission member and can rotate synchronously with the first transmission member. Specifically, the second transmission member 23 may be disposed on the circumference of the first transmission member by means of sleeve or integral molding.

[0122] When multiple second transmission components 23 are spaced apart along the axial direction of the first transmission component, adjacent two second transmission components 23 can cooperate to form a bowl-shaped distance. Taking the first transmission component as an example, which includes a first rotating shaft 21 and a second rotating shaft 22 arranged in parallel, multiple spaced second transmission components 23 are respectively arranged on the first rotating shaft 21 and the second rotating shaft 22.

[0123] When tableware and / or kitchen utensils are placed on the transmission unit, they can be positioned by a set of second transmission members 23 corresponding to the first rotating shaft 21 and the second rotating shaft 22, thereby determining the opening position of the tableware and / or kitchen utensils. One set of second transmission members 23 can correspond to one set of tableware and / or kitchen utensils. Of course, in this embodiment, other methods can also be used to assist in positioning the tableware and / or kitchen utensils. For example, a set of supports can be provided on the dish rack for each set of second transmission members 23 to support the tableware and / or kitchen utensils and prevent them from tipping over.

[0124] Please refer to the following: Figure 8 and Figure 9 In one embodiment, the second spray assembly 4 includes a water supply pipe 40 and a plurality of nozzles 41, wherein the plurality of nozzles 41 are disposed on the water supply pipe 40 and the plurality of nozzles 41 are disposed in a one-to-one correspondence with the plurality of second transmission components 23.

[0125] In this embodiment, the second spray assembly 4 may include a water supply pipe 40 and a plurality of spray nozzles 41. The water supply pipe 40 may be a hollow pipe, and the plurality of spray nozzles 41 may be spaced apart on the water supply pipe 40.

[0126] The water supply pipe 40 can be connected to the liquid supply system. When the second spray assembly 4 is activated, the liquid supply system is connected to the water supply pipe 40, and the liquid from the liquid supply system can be distributed through the water supply pipe 40 to each nozzle 41, from which it is sprayed. The number of nozzles 41 can be the same as the number of second transmission components 23. For example, when there are 5 second transmission components 23, there can be 5 nozzles 41; when there are 4 second transmission components 23, there can be 4 nozzles 41; when there are 3 second transmission components 23, there can be 3 nozzles 41, and so on. Each nozzle 41 corresponds one-to-one with a second transmission component 23, and each second transmission component 23 corresponds one-to-one with tableware and / or kitchenware, allowing each nozzle 41 to specifically clean one piece of tableware and / or kitchenware, improving cleaning precision and efficiency.

[0127] Of course, the number of nozzles 41 can be different from the number of the second transmission component 23. For example, the number of nozzles 41 can be more than the number of the second transmission component 23. In this case, a piece of tableware and / or kitchenware can be rinsed simultaneously by liquid streams sprayed from multiple nozzles 41.

[0128] Please refer to the following: Figure 3 and Figure 4 In one embodiment, the orthogonal projections of the plurality of nozzles 41 on the predetermined plane are spaced at a predetermined distance from the first rotating axis 21 or the second rotating axis 22; or, the orthogonal projections of the plurality of nozzles 41 on the predetermined plane fall between the first rotating axis 21 and the second rotating axis 22.

[0129] In this embodiment, in order to ensure that the liquid flow sprayed from the nozzle 41 can reliably hit the surface of tableware and / or kitchen utensils without being blocked by the first rotating shaft 21 and the second rotating shaft 22 or interfering with other components, the position of the nozzle 41 can be optimized.

[0130] When multiple nozzles 41 are located on one side of the first transmission member, the orthogonal projections of the multiple nozzles 41 on the predetermined plane are spaced at a predetermined distance from the first rotating shaft 21 or the second rotating shaft 22. The numerical value of this predetermined distance is not specifically limited herein, as long as it ensures that the liquid flow sprayed from the nozzles 41 can directly rinse the surface of the tableware and / or kitchen utensils. Figure 4 As shown, when the two second transmission components 23 are spaced sufficiently apart, the nozzle 41 can extend between the first rotating shaft 21 and the second rotating shaft 22, and the orthogonal projection of the nozzle 41 on the predetermined plane falls between the first rotating shaft 21 and the second rotating shaft 22. At this time, the nozzle 41 can extend spatially between the two bowls, and the liquid stream it sprays can act directly on the surface of the bowls with higher pressure over a shorter distance, thereby achieving a better cleaning effect.

[0131] Please refer to the following: Figure 8 , Figure 10 In one embodiment, the second spray assembly 4 includes a water supply pipe 40 and at least one nozzle 41, the nozzle 41 being disposed on the water supply pipe 40 and communicating with the water supply pipe 40.

[0132] The second spray assembly 4 may include a water supply pipe 40 and at least one nozzle 41. The nozzle 41 may be mounted on and connected to the water supply pipe 40. Specifically, the nozzle 41 and the water supply pipe 40 may be fixedly connected or integrally formed. When the nozzle 41 and the water supply pipe 40 are integrally formed, the sealing performance of the nozzle 41 and the water supply pipe 40 at the mating position can be more reliably guaranteed, while also reducing the number of assembly parts and vulnerable parts. When the nozzle 41 and the water supply pipe 40 are fixedly connected, the fixed connection can be a combination of threaded connection and sealing connection, which ensures both the reliability and sealing performance of the connection. Alternatively, the fixed connection can be implemented in other ways, such as a combination of snap-fit ​​sealing connection, etc., as long as the reliability and sealing performance of the connection are guaranteed.

[0133] The number of nozzles 41 can be one or more. Taking the number of nozzles 41 as an example, the water supply pipe 40 can be a hollow pipe, and the multiple nozzles 41 can be arranged at intervals in the water supply pipe 40. The water supply pipe 40 can be connected to a liquid supply system. When the second spray assembly 4 is activated, the liquid supply system is connected to the water supply pipe 40, and the liquid from the liquid supply system can be distributed to each nozzle 41 through the water supply pipe 40 and sprayed out from each nozzle 41.

[0134] In one embodiment, the nozzle 41 has at least one nozzle 410, and when tableware and / or kitchen utensils are placed in the predetermined area, the liquid sprayed from the nozzle 410 can cover the bottom and / or sides of the tableware and / or kitchen utensils.

[0135] In this embodiment, the nozzle 41 may be provided with at least one nozzle 410. For example, when there is only one nozzle 410, the liquid stream sprayed from the nozzle 410 can reach a certain position in a predetermined area. When tableware and / or kitchen utensils are placed in the predetermined area, the liquid stream sprayed from the nozzle 410 can cover the bottom and sides of the tableware and / or kitchen utensils, or the liquid stream sprayed from the nozzle 410 can simultaneously contact the bottom and sides of the tableware and / or kitchen utensils. The shape of the nozzle 410 can be circular, elliptical, etc., and this application does not impose a specific limitation on it. The flow cross-sectional size of the nozzle 410 is also not specifically limited in this application, as long as the liquid supplied by the liquid supply system can reach the designated position in the predetermined area and contact the tableware and / or kitchen utensils when sprayed through the nozzle 410.

[0136] like Figure 9As shown, in one embodiment, the nozzle 41 has two spray holes 410. When tableware and / or kitchen utensils are placed in the predetermined area, the liquid sprayed from one of the spray holes 410 is directed toward the bottom of the tableware and / or kitchen utensils, and the liquid sprayed from the other nozzle 41 is directed toward the side of the tableware and / or kitchen utensils.

[0137] In this embodiment, the nozzle 41 may have two nozzles 410, wherein the liquid jets from the two nozzles 410 can be used to specifically clean the bottom and sides of the tableware and / or kitchenware. For example, when tableware and / or kitchenware are placed in a predetermined area, the liquid jet from one nozzle 410 can be directed towards the bottom of the tableware and / or kitchenware, while the liquid jet from the other nozzle 41 can be directed towards the sides of the tableware and / or kitchenware, thereby achieving full coverage cleaning of the bottom and sides of the tableware and / or kitchenware using a set of nozzles 410 of the nozzle 41.

[0138] In one embodiment, the second spray assembly 4 further includes a connector 42, which is fixedly connected to or integrally formed with the water supply pipe 40, and the nozzle 41 is rotatably connected to the connector 42; the nozzle 41 communicates with the water supply pipe 40 through the connector 42. The nozzle 41 is configured to rotate when liquid is sprayed from the nozzle 41.

[0139] In this embodiment, the second spray assembly 4 further includes a connector 42 rotatably connected to the nozzle 41. This connector 42 serves as an intermediate transition piece, enabling the nozzle 41 to be rotatably connected to the water supply pipe 40 while simultaneously connecting the water path. When the nozzle 41 is rotatably connected in the water supply pipe 40, during use, when the liquid supply system supplies liquid to the water supply pipe 40, the liquid flow through the nozzle 41 causes it to rotate, thereby significantly increasing the cleaning area covered by the nozzle 41. During the cleaning process of tableware and / or kitchenware, at least the following liquid flows overlap: during the rotation of the tableware and / or kitchenware, the liquid flow sprayed by the first spray assembly can make circumferential contact with the tableware and / or kitchenware at one angle, forming a first circular coverage area with a first radius; the liquid flow sprayed by the nozzle 41 of the second spray assembly 4 can make circumferential contact with the tableware and / or kitchenware at another angle, while the liquid flow sprayed by the nozzle 41 itself forms a second circular coverage area with a second radius. The second circular coverage area moves in a circle around the center of the tableware and / or kitchenware. The second circular coverage area partially overlaps with the first circular coverage area, achieving full coverage and multiple cleaning of the tableware and / or kitchenware, thereby effectively improving cleaning efficiency and saving water and electricity.

[0140] Especially when stubborn stains are present on the surface of tableware and / or cookware in the designated area, and tableware and / or cookware are also placed in other areas of the inner liner 1, the first spray component and the second spray component 4, in conjunction with the drive component 2, can perform a combined intensive wash on the tableware and / or cookware in the designated area. This not only effectively improves the cleaning efficiency of the tableware and / or cookware in that designated area, but also significantly shortens the washing time of the entire inner liner, saving water and electricity. Particularly when used for washing a large quantity of tableware that needs to be washed multiple times, it can greatly reduce the user's waiting time and improve the user experience.

[0141] Of course, in this embodiment, it is not excluded that the first spray assembly may not be activated, and only the second spray assembly 4 and the drive assembly 2 may be used to clean tableware and / or kitchenware in a predetermined area. For example, when a small number of tableware and / or kitchenware in a predetermined area need to be cleaned specifically, the diameter of the second circular coverage area may be made larger than the diameter of the opening 60 of the tableware and / or kitchenware, thereby enabling a full-coverage and powerful cleaning of the tableware and / or kitchenware. In this case, since the tableware can be rotated and directly rinsed using the second spray assembly 4 and the drive assembly 2, the aforementioned goals of significantly shortening the cleaning time, saving water and electricity, and improving the cleaning effect can be achieved.

[0142] like Figure 11 As shown, in one embodiment, the nozzle 41 has at least one nozzle hole 410. The nozzle hole 410 is inclinedly disposed on the end face of the nozzle 41. The axis of the nozzle hole 410 is not perpendicular to the end face of the nozzle 41. The angle β between the orthogonal projection of the axis of the nozzle hole 410 on the end face of the nozzle 41 and the radial direction of the movement trajectory of the nozzle 41 is in the range of 0 < β < 180°.

[0143] In this embodiment, to ensure that the nozzle 41 can rotate when liquid is ejected from it, the axial direction of the nozzle 410 can be spatially optimized so that the liquid flow ejected from the nozzle 410 can provide rotational power for the nozzle 41. Specifically, the liquid ejected from the nozzle 410 has a certain force, and the liquid ejection generates a reaction force on the nozzle 41, the direction of which is opposite to the direction of the liquid flow; since the nozzle 410 is spatially inclined on the end face of the nozzle 41, the jetting direction of the liquid flow has a component at least in the tangential direction of the end face of the nozzle 41, and the reaction force of the liquid flow will generate a rotational torque on the nozzle 41, thereby driving the nozzle 41 to rotate around its axis.

[0144] Please refer to the following: Figure 11 and Figure 12In one embodiment, the nozzle 41 has a claw 413 integrally formed on the end face opposite to the nozzle hole 410, and the claw 413 engages with the connector 42.

[0145] In this embodiment, the nozzle 41 can be connected to the connector 42 via a snap-fit ​​connection. Specifically, the nozzle 41 has a front end face for setting the nozzle orifice 410 and a rear end face opposite to the front end face, and a retainer 413 can be provided on the rear end face. Specifically, the retainer 413 can be integrally formed on the rear end face, which ensures both the reliability of the connection and the seamless connection between the two, as well as the sealing of the connection position. Of course, in this embodiment of the application, it is not excluded that the retainer 413 can be provided on the rear end face in other ways.

[0146] The claw 413 can engage with the connector 42. When the claw 413 engages with the connector 42, it facilitates the easy disassembly and assembly of the nozzle 41, making it convenient for individual maintenance and replacement of the nozzle 41 during subsequent use. In particular, when the nozzle 41 experiences malfunctions such as clogging, it is not necessary to disassemble the entire second spray assembly 4, which improves the convenience of subsequent maintenance and replacement and reduces maintenance costs.

[0147] Please refer to the following: Figure 13 , Figure 14 and Figure 15 In one specific embodiment, the nozzle 41 includes a housing 411 and an inner core 412. The nozzle 410 is formed on the housing 411. The inner core 412 is fixedly connected to the connector 42 or integrally formed. The housing 411 and the inner core 412 are sealed and rotatably connected.

[0148] In this embodiment, the nozzle 41 may include a sealed, rotatably connected outer shell 411 and inner core 412. The inner core 412 may be integrally formed or fixedly connected to the connector 42 and is connected to the delivery pipeline. The outer shell 411 may be integrally fitted over the inner core 412, forming a liquid flow cavity between them. A nozzle 410 is provided on the end face of the outer shell 411, and the nozzle 410 is connected to the liquid flow cavity. The inner core 412 may include a hollow columnar structure and can serve as a rotation shaft for the outer shell 411. The inlet end of the inner core 412 can be connected to the water delivery pipeline 40 via the connector 42, and a window may be provided on the side wall opposite to the inlet end to guide the liquid flow into the liquid flow cavity so that it can be sprayed out from the nozzle 410.

[0149] Overall, the nozzle 41 adopts a structural design with a sealed and rotatable connection between the outer shell 411 and the inner core 412. Combined with the fixedly connected inner core 412 and the outer shell 411 with spray holes 410, the functionality and reliability of the nozzle 41 can be significantly improved. The specific analysis is as follows:

[0150] 1. It features dynamic spraying and direction adjustment capabilities. When the inner core 412 is connected and fixed to the connector 42, the outer shell 411 can rotate around the inner core 412, causing the spray nozzles 410 to change direction, thus achieving dynamic adjustment of the spraying direction, enabling multi-angle variable spraying. In use, the outer shell 411 can achieve 360° circumferential scanning spraying through the backlash force of the water flow, without the need for an additional power source, allowing the spray nozzles 410 to cover different areas of the tableware, forming a full-coverage direct spray cleaning.

[0151] 2. It has excellent sealing and leak-proof performance. The outer shell 411 and the inner core 412 adopt a sealing design (such as sealing rings and shaft seal structures) to ensure reliable sealing during rotation, prevent liquid leakage, and maintain the internal high-pressure environment.

[0152] 3. It simplifies the structure and reduces installation and maintenance costs. The inner core 412 is fixed (or integrally formed) with the connector 42, and the outer shell 411 can rotate without additional transmission mechanisms (such as gears or connecting rods), resulting in a compact structure and reduced assembly complexity.

[0153] The outer casing 411 and inner core 412 are detachable (e.g., threaded connection + seal). When the spray nozzle 410 is clogged, only the outer casing 411 needs to be disassembled for cleaning or replacement; there is no need to replace the entire spray head 41 assembly. During use, dishwasher users can clean the spray nozzle 410 of any residue (such as food particles) themselves.

[0154] 4. It has the effect of fluid dynamics optimization. The inner core 412 provides rigid support, stabilizes the water flow output, ensures the position accuracy of the nozzle 410 when the outer shell 411 rotates, and avoids water flow dispersion or pressure fluctuation due to shaking.

[0155] In one embodiment, the second spray assembly 4 is fixedly connected to the wall of the inner liner 1.

[0156] In this embodiment, the second spray assembly 4 can be fixed to the wall of the inner liner 1. For example, the inner liner 1 can be a hollow box structure with a front sidewall facing the user. The front sidewall can be an openable and closable door, a rear sidewall opposite the door, and opposite left and right sidewalls. The second spray assembly 4 can be fixed to the rear sidewall of the inner liner 1 to avoid interference with other mounting or moving parts. Of course, this embodiment does not exclude the possibility that the second spray assembly 4 can be installed on other sidewalls, such as the left or right sidewall, provided that it can be installed without interfering with other parts while still fulfilling its function.

[0157] The method by which the second spray assembly 4 is fixed to the wall of the inner liner 1 is not specifically limited in this application. For example, the second spray assembly 4 can be fixed to the wall of the inner liner 1 in a detachable manner, which facilitates the subsequent disassembly of the second spray assembly 4 for separate inspection and replacement. This detachable method can be a snap-fit ​​or other method that facilitates installation and disassembly, and is not limited to any particular method in this application.

[0158] Please refer to the following: Figures 1 to 2 In one embodiment, the cleaning device further includes a first dish basket 51, and the predetermined area is located within the first dish basket 51; the first dish basket 51 is capable of relative movement with the inner wall surface of the inner liner 1; when the first dish basket 51 moves to the point of being fully inside the inner liner 1, the second spray assembly 4 is capable of spraying liquid onto the tableware and / or kitchen utensils placed in the predetermined area.

[0159] In this embodiment, the washing device may include a first dish basket 51 for placing tableware and / or kitchen utensils. The predetermined area is located within the first dish basket 51. Specifically, a driving component may be provided in the predetermined area, which can rotate and clean the tableware and / or kitchen utensils placed within the predetermined area during washing, while simultaneously being sprayed and cleaned by the second spray component 4 and the first spray component.

[0160] The first bowl basket 51 can be slidably connected within the inner liner 1. For example, a sliding groove and pulley cooperation structure can be provided between the inner wall of the inner liner 1 and the first bowl basket 51. When the door of the inner liner 1 is opened, the first bowl basket 51 can move relative to the inner wall of the inner liner 1, thereby pulling out or pushing back the first bowl basket 51. For example, when a user needs to place tableware and / or kitchenware to be washed, the first bowl basket 51 can be pulled out; after placing the tableware and / or kitchenware, the first bowl basket 51 can be pushed back into the inner liner 1. When the first bowl basket 51 moves to be fully inside the inner liner 1, the second spray assembly 4 can correspond to the tableware and / or kitchenware placed in a predetermined area, allowing the second spray assembly 4 to spray liquid onto the tableware and / or kitchenware placed in the predetermined area.

[0161] Please refer to the following: Figure 16 or Figure 17 In one embodiment, the cleaning device may further include: a washing pump 7 and a water distribution valve 8; the water distribution valve 8 includes an inlet, a first outlet and a second outlet disposed on the valve body; the inlet is connected to the washing pump 7, the first outlet is connected to the first spray assembly, and the second outlet is connected to the second spray assembly 4.

[0162] In this embodiment, the cleaning device may also include a washing pump 7 and a water distribution valve 8 upstream of the first spray assembly and the second spray assembly 4. The washing pump 7 provides driving force for the liquid flow of the liquid supply system to the first spray assembly and / or the second spray assembly 4. The water distribution valve 8 can be used to control the connection between the liquid supply system and the first spray assembly and the second spray assembly 4.

[0163] Specifically, the water distribution valve 8 may include an inlet, a first outlet, and a second outlet disposed on the valve body. The inlet is connected to the washing pump 7, the first outlet is connected to the first spray assembly, and the second outlet is connected to the second spray assembly 4. The specific form of the water distribution valve 8 is not specifically limited here, as long as it can control the opening and closing of the inlet and outlet. In this embodiment, taking a valve core disposed in the valve body as an example, the valve core can rotate relative to the valve body. When the valve core rotates to the first position, the first outlet is opened, and the washing pump 7 can drive the liquid flow to the first spray assembly; when the valve core rotates to the second position, the second outlet is opened, and the washing pump 7 can drive the liquid flow to the second spray assembly 4; when the valve core rotates to the third position, both the first outlet and the second outlet can be opened, and the washing pump 7 can drive the liquid flow to the first spray assembly and the second spray assembly 4.

[0164] like Figure 16 As shown, in one embodiment, the cleaning device further includes a first dish basket 51, and the predetermined area is located within the first dish basket 51; the first spray assembly includes a lower spray arm 31, which communicates with the first outlet; the lower spray arm 31 is disposed below the first dish basket 51.

[0165] In this embodiment, taking the predetermined area located within the first dish basket 51 as an example, the first spray assembly is a spray assembly designed for the entire inner liner 1. The first spray assembly may include a lower spray arm 31, which is connected to a first outlet. The lower spray arm 31 may be positioned below the first dish basket 51. During use, the lower spray arm 31 can rotate, and the cleaning area formed by its sprayed liquid flow can cover all areas of the first dish basket 51 (including the aforementioned predetermined area), ensuring that all tableware and / or kitchen utensils in the first dish basket 51 can be cleaned.

[0166] like Figure 17As shown, in one embodiment, the cleaning device further includes a second basket 52 and a third spray assembly, the second basket 52 being located above the first basket 51; the water distribution valve 8 further includes a third outlet; the third spray assembly includes an upper spray arm 32 and a top spray arm 33, the upper spray arm 32 and the top spray arm 33 being respectively connected to the third outlet; the upper spray arm 32 is disposed between the first basket 51 and the second basket 52, and the top spray arm 33 is disposed above the second basket 52.

[0167] In this embodiment, the washing device may further include a second dish rack 52, which may be located above the first dish rack 51. Overall, when this washing device is used as a dishwasher, multiple dish racks can be provided to ensure the dishwasher's washing capacity, enabling the simultaneous washing of a large number of tableware and / or kitchen utensils. Specifically, the number of dish racks can be set according to actual needs, and may be two, three, or even more. In this embodiment, the washing device including the first dish rack 51 and the second dish rack 52 is used as an example for illustration.

[0168] When the cleaning device also includes a second dish basket 52, in order to spray and clean the tableware and / or kitchen utensils inside the second dish basket 52, the cleaning device may include multiple spray assemblies. For example, the cleaning device may include a third spray assembly. The third spray assembly may include an upper spray arm 32 and a top spray arm 33. The upper spray arm 32 may be positioned between the first dish basket 51 and the second dish basket 52, and the top spray arm 33 may be positioned above the second dish basket 52.

[0169] To share the same liquid supply system, a third outlet can be provided on the water distribution valve 8. The upper spray arm 32 and the top spray arm 33 can be connected to the third outlet respectively. The upper spray arm 32 and the top spray arm 33 are used for synchronous operation. For example, when it is necessary to clean all tableware and / or kitchen utensils in the inner tank 1, the third outlet is also connected to the washing pump 7, and the washing pump 7 drives the liquid flow through the third outlet to the upper spray arm 32 and the top spray arm 33.

[0170] In one embodiment, the water distribution valve 8 further includes a fourth outlet, which is in communication with the fluid inlet of the drive assembly 2.

[0171] In this embodiment, in order to share the same liquid supply system and improve the system integration, a fourth outlet can be provided on the water distribution valve 8. The first outlet can be connected to the fluid inlet of the drive component 2, thereby providing liquid flow to the drive component 2.

[0172] In one embodiment, the water distribution valve 8 includes at least a first state and a second state; when the water distribution valve 8 is in the first state, the liquid flowing in from the inlet can simultaneously flow to the first outlet and the second outlet; when the water distribution valve 8 is in the second state, the liquid flowing in from the inlet can simultaneously flow to the second outlet and the fourth outlet.

[0173] In this embodiment, the cleaning device may include multiple cleaning modes, and the water distribution valve 8 has different connection states in different cleaning modes.

[0174] For example, when the water distribution valve 8 is in the first state, the inlet of the water distribution valve 8 can be connected to the first outlet and the second outlet. The liquid flow of the liquid supply system can be supplied to the downward spray arm 31 and the second spray assembly 4 through the water distribution valve 8 to spray the tableware and / or kitchenware in the predetermined area, thereby wetting the tableware and / or kitchenware in the predetermined area so that the stubborn stains attached to the tableware and / or kitchenware can be cleaned efficiently in the future.

[0175] For example, when the water distribution valve 8 is in the second state, the inlet of the water distribution valve 8 can be connected to the second outlet and the fourth outlet, and the liquid flow of the liquid supply system can be supplied to the second spray assembly 4 and the drive assembly 2 through the water distribution valve 8 to perform rotation and direct spray cleaning on the tableware and / or kitchen utensils in the predetermined area.

[0176] Of course, the state of the water distribution valve 8 is not limited to the examples above. For example, when the capacity of the washing pump 7 is sufficient, or when the number of washing pumps 7 increases from one to two or more, the water distribution valve 8 can have more different states, and its inlet can be connected to more outlets at the same time.

[0177] It should be noted that in the description of this application, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more.

[0178] The various embodiments described in this specification are presented in a progressive manner. The same or similar parts between the embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.
