[0002] Dishwashers, integrated washing and disinfecting machines and other washing machines with washing functions free users' hands by automatically washing dishes, thus improving the quality of life of users. Since users' actual washing needs may not be the same every time, large-capacity washing machines will cause waste when users have small washing needs, while small-capacity washing machines will cause users' large washing needs to not be met.

[0003] In order to solve the above problems, the related technology provides a washing machine, which includes an inner tank, a partition and a water supply system. The partition is arranged in the inner tank and divides the washing chamber of the inner tank into two independently arranged washing areas. Each washing area has an upper spray arm and a lower spray arm, and each washing area is equipped with a water supply system. When the user washes a small amount of tableware, he can choose any of the two washing areas according to the needs. When the user washes a large amount of tableware, he can use both washing areas at the same time, thereby meeting the user's small washing needs and large washing needs and improving the user's use experience.

[0004] However, the two water supply systems not only make the cost of the cleaning machine higher, but also occupy a larger space, which is not conducive to improving the space utilization of the cleaning machine.

[0049] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0050] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0051] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects before and after are in an "and / or" relationship.

[0052] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0053] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0054] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0055] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that the directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0056] Figure 1 A schematic structural diagram of a cleaning machine provided in an embodiment of the present application is shown. Figure 2 The internal structure diagram of the cleaning machine provided in the embodiment of the present application is shown. Figure 1 to Figure 2 As shown, the cleaning machine includes an inner tank 100, a base 200 and a door body 300. The bottom of the inner tank 100 is fixedly connected to the base 200, and the inner tank 100 has an opening. The door body 300 is rotatably mounted on the base 200 and is used to open or close the opening of the inner tank 100.

[0057] In order to meet the diverse cleaning needs of users, a partition 400 is provided in the inner tank 100, and the partition 400 divides the internal space of the inner tank 100 into two independently arranged first washing areas 101 and second washing areas 102. The first washing area 101 is provided with a first upper spray arm 502 and a first lower spray arm 501, and the second washing area 102 is provided with a second upper spray arm 602 and a second lower spray arm 601. Each spray arm can spray cleaning water to the corresponding washing area, thereby achieving cleaning of the tableware.

[0058] For the convenience of description, the upper side of the washing machine in use is defined as the upper side, and the direction corresponding to the upper side is defined as the lower side; the direction of the door body 300 is defined as the front side, and the direction away from the door body 300 is defined as the back side; when the user faces the door body 300, the left side of the user is defined as the left side, and the right side of the user is defined as the right side. In this embodiment, the first washing area 101 is in the right area of ​​the inner tank 100, and the second washing area 102 is in the left area of ​​the inner tank 100.

[0059] In this embodiment, the number of the first lower spray arms 501 is two, and the two first lower spray arms 501 are arranged at intervals in the front-to-back direction. The number of the first upper spray arm 502, the second lower spray arm 601, and the second upper spray arm 602 is one. Of course, in other embodiments, the number and arrangement of the first lower spray arm 501, the first upper spray arm 502, the second lower spray arm 601, and the second upper spray arm 602 can be designed as needed, and are not limited here.

[0060] The cleaning machine further comprises a water supply system, which can selectively supply cleaning water to the first lower spray arm 501, the first upper spray arm 502, the second lower spray arm 601 and the second upper spray arm 602 to achieve multiple cleaning modes.

[0061] The water supply system includes a sink bottom plate 1 and a water distributor 2. The sink bottom plate 1 is installed at the bottom of the inner tank 100 and is located in the base 200. The water distributor 2 is installed at the bottom of the sink bottom plate 1 and can cooperate with the sink bottom plate 1 to realize different water distribution and supply modes.

[0062] In addition, the cleaning machine also includes a first filter 701 and a second filter 702. The first filter 701 is installed on the bottom plate 1 of the sink at a position corresponding to the first washing area 101 and is used to filter large volume residues; the second filter 702 is installed on the bottom plate 1 of the sink at a position corresponding to the second washing area 102 and is used to filter large volume residues. It should be noted that due to the modeling and model display of the filter, Figure 2 The first filter 701 and the second filter 702 do not show the filter mesh structure.

[0063] Figure 3 A schematic diagram of an exploded view of the water divider 2 and the sink bottom plate 1 provided in an embodiment of the present application is shown. Figure 4 The schematic diagram of the structure of the sink bottom plate 1 provided in the embodiment of the present application is shown. Figure 3 to Figure 4 Combined with Figure 2 As shown, a first lower water outlet hole 11, a first upper water outlet hole 12, a second lower water outlet hole 13 and a second upper water outlet hole 14 are provided on the sink bottom plate 1. The first lower water outlet hole 11 is used to communicate with the first lower spray arm 501, the first upper water outlet hole 12 is used to communicate with the first upper spray arm 502, the second lower water outlet hole 13 is used to communicate with the second lower spray arm 601, and the second upper water outlet hole 14 is used to communicate with the second upper spray arm 602.

[0064] Figure 5 The figure shows an exploded schematic diagram of the sink bottom plate 1 and the water guide member provided in the embodiment of the present application. Figure 5 Combination Figure 4As shown, the water supply system also includes a first lower water guide 31, a first upper water guide 32, a second lower water guide 33 and a second upper water guide 34. The surface of the water tank bottom plate 1 facing the inner pot 100 has a first lower water guide groove 15, a first upper water guide groove 16, a second lower water guide groove 17 and a second upper water guide groove 18; the first lower water guide 31 is buckled outside the first lower water guide groove 15 and forms a first lower water guide pipe connecting the first lower water outlet 11 and the first lower spray arm 501 with the first lower water guide groove 15; the first upper water guide 32 is buckled A first upper water conduit is formed outside the first upper water conduit groove 16 and connected with the first upper water conduit groove 16 to connect the first upper water outlet hole 12 and the first upper spray arm 502; the second lower water conduit member 33 is buckled outside the second lower water conduit groove 17 and forms a second lower water conduit with the second lower water conduit groove 17 to connect the second lower water outlet hole 13 and the second lower spray arm 601; the second upper water conduit member 34 is buckled outside the second upper water conduit groove 18 and forms a second upper water conduit with the second upper water conduit groove 18 to connect the second upper water outlet hole 14 and the second upper spray arm 602.

[0065] It is understandable that by forming a water pipe through the cooperation of the water guide groove and the water guide member, not only can the space occupied by the water guide pipe as a whole be reduced and the space utilization rate be improved, but also the weight of the water guide members and the water tank bottom plate 1 as a whole can be reduced, thereby realizing a lightweight design of the cleaning machine. In addition, when the water guide member is installed on the water tank bottom plate 1, the outer surface of the water guide member and the outer surface of the water tank bottom plate 1 are smoothly transitioned to ensure the consistency of the outer surface of the water tank bottom plate 1 and the overall outer surface of the water guide member, which can facilitate the assembly of the first filter screen 701 and the second filter screen 702.

[0066] In this embodiment, the first upper water guide 32 and the second upper water guide 34 are integrally formed structures, and the first lower water guide 31 and the second lower water guide 33 are split structures. In other embodiments, the first lower water guide 31, the first upper water guide 32, the second lower water guide 33 and the second upper water guide 34 are all separate structures independent of each other, or any two, three or four of them may be integrally formed structures, which is not limited here. For example, the water guide may be a sheet metal structure, and the sheet metal structure is fixedly connected to the bottom plate 1 of the water tank by welding, such as by friction welding.

[0067] In addition, in this embodiment, since there are two first lower spray arms 501, the shape of the first lower water guide 31 is roughly T-shaped, and the first water guide has a water inlet and two water outlets, one water inlet is connected to the first lower water outlet 11, and the two water outlets are respectively connected to the two first lower spray arms 501. It can be understood that when the number of the remaining spray arms is adjusted, the structure of the corresponding water guide can be adjusted with reference to the above method, and no further examples are given here.

[0068] like Figure 4 Combination Figure 2As shown, the cleaning machine also includes a first water pipe 801 and a second water pipe 802 . The first water pipe 801 is used to connect the first upper water pipe and the first upper spray arm 502 , and the second water pipe 802 is used to connect the second upper water pipe and the second upper spray arm 602 .

[0069] Figure 6 A schematic top view of the water divider 2 provided in an embodiment of the present application is shown. Figure 7 Shows Figure 6 The cross-sectional view of the middle water distributor 2 at AA. Figure 6 to Figure 7 Combined with Figure 3 As shown, the water divider 2 includes a water divider seat 21, a water divider sheet 22 and a driver 23. The water divider sheet 22 is rotatably mounted on the water divider seat 21 and cooperates with the water divider seat 21 to form a accommodating chamber 210, which is used to cache cleaning water. The water divider sheet 22 is provided with at least four water divider holes that are all connected to the accommodating chamber 210; the driver 23 is mounted on the water divider seat 21 and is located outside the accommodating chamber 210. The driver 23 is used to drive the water divider sheet 22 to rotate relative to the sink bottom plate 1, so that any number of water outlet holes among the first lower water outlet hole 11, the first upper water outlet hole 12, the second lower water outlet hole 13 and the second upper water outlet hole 14 are connected to the accommodating chamber 210 through the water divider holes.

[0070] Compared with the water supply system in the related art which can only make the upper spray arm and the lower spray arm in a single washing area work at the same time or not work at the same time, the washing machine provided in the present application can realize the opening or closing of the upper spray arm and the lower spray arm individually adjusted according to the washing needs, thereby meeting the diverse washing needs of users.

[0071] In one embodiment, see Figure 3 The water diverter plate 22 is provided with a first water diverter hole 221, a second water diverter hole 222, a third water diverter hole 223, a fourth water diverter hole 224 and a fifth water diverter hole 225, all of which are connected to the accommodating chamber 210. During the rotation of the water diverter plate 22, any two of the first lower water outlet hole 11, the first upper water outlet hole 12, the second lower water outlet hole 13 and the second upper water outlet hole 14 are connected to the accommodating chamber 210 through any two of the first water diverter hole 221, the second water diverter hole 222, the third water diverter hole 223, the fourth water diverter hole 224 and the fifth water diverter hole 225. In other words, the designer can reasonably design the number of water diverter holes, the layout of the water diverter holes and the layout of the water outlet holes according to the required cleaning mode to meet the cleaning requirements of different cleaning modes.

[0072] In this embodiment, the cleaning modes mainly include four types. The first is that the first washing zone 101 is cleaned alone. At this time, only the first lower spray arm 501 and the first upper spray arm 502 can spray water; the second is that the second washing zone 102 is cleaned alone. At this time, only the second lower spray arm 601 and the second upper spray arm 602 can spray water; the third is that the upper spray arms of the first washing zone 101 and the second washing zone 102 are cleaned. At this time, only the first upper spray arm 502 and the second upper spray arm 602 can spray water; the fourth is that the lower spray arms of the first washing zone 101 and the second washing zone 102 are cleaned. At this time, only the first lower spray arm 501 and the second lower spray arm 601 can spray water.

[0073] When the first washing area 101 works alone, the layout positions of the first water diversion hole 221 and the second water diversion hole 222 relative to the rotation axis of the water diversion plate 22 are the same as the layout positions of the first lower water outlet hole 11 and the first upper water outlet hole 12 relative to the rotation axis of the water diversion plate 22, and when the first water diversion hole 221 is connected to the first lower water outlet hole 11 and the second water diversion hole 222 is connected to the first upper water outlet hole 12, the remaining water outlet holes are not connected to the accommodating chamber 210.

[0077] Continue to see Figure 7 and Figure 3 As shown, the water divider 2 further includes an adapter 24, which is rotatably mounted on an end of the water divider seat 21 away from the water divider sheet 22, and the driving end of the driver 23 is synchronously rotatably connected with the adapter 24, and a portion of the adapter 24 extends into the accommodating chamber 210 and is synchronously rotatably connected with the water divider sheet 22. The adapter 24 can be used to realize the connection between the driver 23 and the water divider sheet 22, and can prevent the driver 23 from directly contacting the water in the accommodating chamber 210, thereby ensuring the safety and stability of the driver 23.

[0078] In this embodiment, the adapter 24 includes an adapter plate 241 and an adapter shaft 242 connected to the adapter plate 241. The adapter plate 241 is located outside the accommodating chamber 210. One end of the adapter shaft 242 away from the adapter plate 241 extends into the accommodating chamber 210 and is synchronously rotatably connected with the water diversion plate 22.

[0079] It should be noted that "synchronous rotation connection" means that the two connected parts can rotate synchronously. The connection between the two parts can be a fixed connection or a keyway connection. The designer can design it according to specific needs and there is no limitation here.

[0080] The adapter shaft 242 is in the shape of a stepped shaft, the water diversion seat 21 has a stepped hole for accommodating the adapter shaft 242, and a seal 28 is provided between the shaft shoulder of the adapter shaft 242 and the step surface of the stepped hole to improve the sealing between the adapter 24 and the water diversion seat 21 and prevent water from leaking from the connection position between the water diversion seat 21 and the adapter 24.

[0081] In this embodiment, the water diversion seat 21 has a receiving groove on one side facing the water diversion plate 22. The water diversion plate 22 can be rotatably installed at the open part of the receiving groove and cooperate with the receiving groove to form a receiving chamber 210. The receiving chamber 210 is used to cache cleaning water. The water in the receiving chamber 210 is distributed to different water outlets through the rotation of the water diversion plate 22 to achieve different cleaning modes.

[0082] The water divider 2 also includes an elastic member 27, which is located between the water divider sheet 22 and the water divider seat 21. The water tank bottom plate 1 is sealed with the water divider seat 21, and the elastic member 27 is used to make the water divider sheet 22 close to the water tank bottom plate 1 to prevent a large amount of water in the accommodating cavity 210 from flowing from the gap between the water divider sheet 22 and the inner wall of the accommodating cavity 210 to between the water divider sheet 22 and the water tank bottom plate 1.

[0083] In order to facilitate the assembly and positioning of the elastic member 27, the receiving groove of the water diversion seat 21 is provided with a stepped guide column 211 extending toward the water diversion sheet 22, and one end of the elastic member 27 is sleeved outside the stepped guide column 211 and abuts against the shoulder of the stepped guide column 211. The stepped guide column 211 can realize the positioning and guiding of the elastic member 27, and ensure the stability of the elastic member 27.

[0084] Furthermore, the surface of the water dividing plate 22 facing the receiving groove has a positioning column 226 extending downward, and the other end of the elastic member 27 is sleeved outside the positioning column 226 to achieve positioning and assembly of the elastic member 27 and ensure the stability of the elastic member 27.

[0085] The water distributor 2 further includes a fixing seat 25, which is fixed to the water distributor seat 21 and is located outside the accommodating chamber 210. The driver 23 is fixed to the fixing seat 25, and the driving end of the driver 23 passes through the fixing seat 25 and is synchronously rotatably connected to the adapter plate 241. In this embodiment, the driver 23 is a servo motor, the housing of the servo motor is fixed to the fixing seat 25, and the driving end of the servo motor passes through the fixing seat 25 and is synchronously rotatably connected to the adapter plate 241.

[0086] In order to realize automatic control of the cleaning mode of the cleaning machine, the water divider 2 also includes a sensor 26, which is fixed to the fixing seat 25 and is communicatively connected with the driver 23. The outer periphery of the adapter plate 241 has a plurality of trigger protrusions 2411. When the adapter plate 241 rotates until the trigger protrusion 2411 thereon is adjacent to the sensor 26, the sensor 26 can be triggered.

[0087] In this embodiment, the adapter plate 241 has four trigger protrusions 2411, and the four trigger protrusions 2411 represent four cleaning modes respectively. When the trigger protrusion 2411 of the adapter plate 241 rotates to be adjacent to the sensor 26, the driver 23 stops rotating. At this time, the corresponding water outlet is connected to the accommodating cavity 210 through the water diversion hole, so that the corresponding spray arm can obtain the cleaning water supply. For example, the sensor 26 can be a micro switch, which is fixed on the fixing seat 25 and has a protrusion 261. When the trigger protrusion 2411 is adjacent to the protrusion 261, the micro switch responds and transmits a signal to the control system of the cleaning machine, and then the control system issues an instruction to control the driver 23 to stop, and then the corresponding cleaning mode is performed.

[0088] Figure 8 Shows Figure 4 A schematic cross-sectional view of the middle water tank bottom plate 1 at position BB. Fig. 9 FIG. 1 shows a bottom view of the sink bottom plate 1 according to an embodiment of the present application. Figures 8 to 9 Combined with Figure 4 As shown, the portion of the water tank bottom plate 1 corresponding to the first washing area 101 has a first water tank portion 191 that is recessed in a direction away from the first washing area 101, and the portion of the water tank bottom plate 1 corresponding to the second washing area 102 has a second water tank portion 192 that is recessed in a direction away from the second washing area 102, and the first water tank portion 191 and the second water tank portion 192 are connected through a connecting pipe 4. In this way, the water in the two washing areas can be discharged through one drainage system without setting up two drainage systems, which can reduce costs.

[0089] The connecting pipe 4 has a first connecting passage 41 and a second connecting passage 42 . The first connecting passage 41 is used to connect the middle of the first water tank 191 and the second water tank 192 . The second connecting passage 42 is used to connect the bottom of the first water tank 191 and the second water tank 192 .

[0090] The water supply system further includes a pressure pump 5, which is connected to the second water tank portion 192 and the accommodating chamber 210 of the water distributor 2 at the same time, so as to realize the reuse of washing water and save water resources.

[0091] Furthermore, the cleaning machine further includes a drain pump 900, which is connected to the second water tank 192 and is used to drain the water in the first water tank 191 and the second water tank 192 out of the cleaning machine. It is understandable that when the booster pump 5 is working, the drain pump 900 is not working. When the cleaning operation is completed, the booster pump 5 stops working and the drain pump 900 starts working to discharge the cleaning water out of the cleaning machine.

[0092] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
