[0041] Due to the washing requirement for a small number of tableware in dishwashers on the market, generally mainstream dishwashers are equipped with a function of washing in layers. However, the layer-by-layer washing is completed within the same large cavity without physical separation. The problem is that the pollutants from the upper-layer washing will fall onto the tableware in the lower layer, and the pollutants will also splash onto the upper-layer tableware along with the water flow during the lower-layer washing. Therefore, no matter whether the upper-layer washing or the lower-layer washing is selected, in fact, both the upper spray arm and the lower spray arm need to work to wash the tableware clean. This not only makes the layer-by-layer washing not energy-saving and time-saving, but also fails to achieve different functions for the upper and lower cavities.

[0042] The layer-by-layer washing only supports the lower-layer washing and does not support the upper-layer washing, which is contrary to the user's high-frequency and small-quantity washing requirement of using the upper layer (washing with the upper layer can avoid bending over for small-quantity washing, and the volume of the upper cavity is generally smaller than that of the lower cavity, which can reduce energy consumption and washing and drying time).

[0043] Moreover, since there is only one set of water return and filtration system, when the upper and lower layers are washed simultaneously, the water paths of the upper and lower cavities are connected to the same water storage component, so the water in the upper and lower cavities will be mixed together, making it difficult to achieve the reasonable use of the following scenarios: storing tableware in the lower layer while washing in the upper layer; washing tableware (lightly polluted) in the upper layer and washing non-tableware (heavily polluted) in the lower layer; washing baby tableware in the upper layer and washing other tableware in the lower layer. In the related technology, when washing in separate cavities, the spray arms in the two cavities share the recycled water, resulting in the mixing of the water in the two cavities when the two cavities achieve different functions, and it is easy to have problems such as odor mixing.

[0044] In view of the above problems, the following will combine Figures 1 to 6 to describe the dishwasher of the present application:

[0045] The dishwasher according to the first aspect embodiment of the present utility model includes a machine body 1, a partition member 2, a first water cup assembly 5, a second water cup assembly 6 and a spray arm structure. The machine body 1 is provided with an inner cavity; the partition member 2 is arranged in the inner cavity, and the partition member 2 divides the inner cavity into a first cavity 3 and a second cavity 4; at least part of the first water cup assembly 5 is connected to the partition member 2, and the first water cup assembly 5 is used for receiving the drainage of the first cavity 3; the spray arm structure includes a first spray arm 7 and a second spray arm 8. The first spray arm 7 is arranged in the first cavity 3, and the second spray arm 8 is arranged in the second cavity 4. The drainage port of the first water cup assembly 5 is connected with a first drainage pipeline 13, and the water inlet of the first spray arm is connected with a first water inlet pipeline 14, and the first drainage pipeline 13 and the first water inlet pipeline 14 are communicated with each other.

[0046] It should be noted that the first water cup assembly 5 can be respectively connected to the partition member 2 and the rear side wall of the inner cavity to be away from the center of the inner cavity, so as to avoid interfering with the placement of the tableware in the inner cavity. Of course, in other embodiments, the first water cup assembly 5 can also be respectively connected to the partition member 2 and the two side walls of the inner cavity of the dishwasher, which is not limited herein as long as part of the first water cup assembly 5 is connected to the partition member 2, so as to facilitate the water in the first cavity 3 to flow into the first water cup assembly 5 along the partition member 2.

[0047] Please refer to Figures 1 to 3 According to the dishwasher of the embodiment of the present utility model, the inner cavity of the body 1 is divided into an independent first cavity 3 and a second cavity 4 by a partition member 2. The first cavity 3 and the second cavity 4 can work independently, so that the two cavities can achieve different functions. The first spray arm 7 sprays water for cleaning in the first cavity 3. The water after cleaning in the first cavity 3 can be collected by the first water cup assembly 5, and the first water cup assembly 5 drains water through the first drainage pipeline 13 and is connected to the first spray arm 7 through the first water inlet pipeline 14. The first drainage pipeline 13 is connected to the first water inlet pipeline 14, so that the stored water of the first water cup assembly 5 is supplied for the first spray arm 7 to recycle; and, the second spray arm 8 sprays water for cleaning in the second cavity 4. In this way, the recycled water of the first spray arm 7 can be provided by the first water cup assembly 5, and the water used by the second spray arm 8 can be provided by external water supply. The water used by the first spray arm 7 and the second spray arm 8 will not be mixed to avoid the problem of smell mixing, so that the first cavity 3 and the second cavity 4 can clean different tableware or other items respectively.

[0048] According to an embodiment of the present utility model, the drainage port of the first water cup assembly 5 is located on the side wall of the first water cup assembly 5. The first drainage pipeline 13 extends from the drainage port of the first water cup assembly 5 to the bottom of the second cavity 4, and the water outlet of the first drainage pipeline 13 is lower than the second cavity 4.

[0049] It can be understood that the drainage port of the first water cup assembly 5 discharges from the side wall, so that the drainage port can face the rear side wall of the inner cavity of the dishwasher, so as to avoid the drainage port of the first water cup assembly 5 draining water from the bottom, thereby avoiding occupying the inner cavity space. In this way, the first drainage pipeline 13 can be arranged on the rear side wall of the inner cavity of the dishwasher. The water inlet end of the first drainage pipeline 13 can extend horizontally to connect to the drainage port of the first water cup assembly 5, and the other end of the first drainage pipeline 13 extends vertically to extend to the bottom of the second cavity 4, that is, the water outlet of the first drainage pipeline 13 is lower than the second cavity 4 to be connected to a pump body, and water is pumped from the first water inlet pipeline 14 to the first spray arm 7 through the pump body. At the same time, it can make the water discharged from the first drainage pipeline 13 completely avoid the tableware in the second cavity 4, that is, it does not affect the work of drying and hosting in the second cavity 4.

[0050] According to an embodiment of the present utility model, the minimum inner diameter of the first drainage pipeline 13 is greater than or equal to the inner diameter of the drainage port of the first water cup assembly 5. In this way, it is ensured that the maximum fluid flow rate discharged from the drainage port of the first water cup assembly 5 will not exceed the water discharge volume of the first drainage pipeline 13, and the first drainage pipeline 13 can drain water smoothly. It should be noted that the inner diameter of the first drainage pipeline 13 refers to the size of the passage for flowing fluid, and its cross-section can be circular, square, oval, etc., which is not limited here.

[0051] According to an embodiment of the present utility model, a seal is connected between the first drain pipe 13 and the drain outlet of the first water cup assembly 5. Exemplarily, the first drain pipe 13 and the drain outlet of the first water cup assembly 5 are sleeved with each other, and a sealing ring is clamped therebetween. The sealing ring can be a rubber ring, a silica gel ring, etc., to prevent water seepage at the connection between the two.

[0052] According to an embodiment of the present utility model, the dishwasher further includes a second water cup assembly 6. The second water cup assembly 6 is disposed below the second cavity 4. The second water cup assembly 6 is used to receive the drainage of the second cavity 4. The drain outlet of the second water cup assembly 6 is connected to a second drain pipe 19. The water inlet of the second spray arm 8 is connected to a second water inlet pipe 18. The second drain pipe 19 and the second water inlet pipe 18 are connected and communicated with each other.

[0053] It can be understood that after the dishwasher provides a certain amount of water to the first spray arm 7 and the second spray arm 8, the water in the first cavity 3 and the second cavity 4 can be received in the water storage spaces of the first water cup assembly 5 and the second water cup assembly 6 for the first spray arm 7 and the second spray arm 8 to recycle and repeatedly wash the tableware. The first water cup assembly 5 stores a certain amount of water first and then supplies it to the first spray arm 7, which can avoid the instability of the water flow rate at various places in the first cavity 3 resulting in unstable water output of the first spray arm 7. The certain amount of stored water in the first water cup assembly 5 can continuously supply water for the first spray arm 7 to spray, ensuring the cleaning effect and avoiding intermittent water spraying. The second water cup assembly 6 is the same as the first water cup assembly 5 and will not be elaborated here. Optionally, the first spray arm 7 is installed on the inner wall of the first cavity 3 and is provided with spray holes to spray and clean the tableware in the first cavity 3. Similarly, the second spray arm 8 is installed on the inner wall of the second cavity 4 and is provided with spray holes to spray and clean the tableware in the second cavity 4.

[0054] Please refer to Figure 2 and Figure 3 , according to an embodiment of the present utility model, the first cavity 3 is located above the second cavity 4, and the first water cup assembly 5 is installed on the partition member 2. It can be understood that the first cavity 3 and the second cavity 4 are distributed in an up-and-down structure, which is convenient for users to use only the upper first cavity 3 for a small amount of washing without bending down. Moreover, the volume of the upper first cavity 3 is generally smaller than that of the lower second cavity 4, which can reduce energy consumption and washing and drying time. The first water cup assembly 5 is installed on the partition member 2, which is convenient for the water in the first cavity 3 to flow into the first water cup assembly 5 and convenient for receiving and draining water.

[0055] Such as Figure 3As shown, according to an embodiment of the present utility model, the first spray arm 7 is rotatably installed on one side of the partition member 2 facing the first cavity 3; Exemplarily, the first spray arm 7 is disposed on the upper surface of the partition member 2, and a shaft hole is provided at the center of the partition member 2. The first spray arm 7 is rotatably connected to the shaft hole through a rotating shaft. At the same time, the rotating shaft may be provided with a communication channel for communicating with a pipeline to realize the water inlet of the first spray arm 7.

[0056] In other embodiments, the dishwasher includes a first basket, the first basket is disposed in the first cavity 3, and the first spray arm 7 is rotatably installed on the first basket. It can be understood that the first basket is used to place items to be cleaned, and the first spray arm 7 is rotatably connected to the bottom of the first basket, so as to spray water on the items to be cleaned on the first basket for cleaning.

[0057] As Figure 4 and Figure 5 As shown, according to an embodiment of the present utility model, at least a part of the first water cup assembly 5 is connected to the bottom of the partition member 2, a collecting port 9 is provided above the partition member 2, the collecting port 9 communicates with the water storage space of the first water cup assembly 5, and the water in the first cavity 3 flows into the water storage space of the first water cup assembly 5 through the collecting port 9.

[0058] In this embodiment, the sewage generated after cleaning in the first cavity 3 enters the water storage space of the first water cup assembly 5 through the collecting port 9. A filter element 10 may be provided in the first water cup assembly 5 to filter the sewage for convenient recycling. The water in the first water cup assembly 5 can flow through a circulation pipeline and then flow to the first spray arm 7 again to realize water circulation.

[0059] According to an embodiment of the present utility model, a filter element 10 is provided on the partition member 2, and the filter element 10 is laid around the collecting port 9. By providing the filter element 10 on the partition member 2, the filter element 10 is used to filter food residues, etc., to avoid the recycled water from being too turbid, which is beneficial to improving the cleaning effect. In this way, the partition member 2 not only plays a role in physically separating the inner cavity, but also can realize the filtering function on the partition member 2, which can meet the diverse usage requirements of users.

[0060] Please refer to Figure 3 and Figure 6 , according to an embodiment of the present utility model, the dishwasher further includes a washing pump 12. The circulation pipeline includes a first drain pipeline 13 and a first water inlet pipeline 14. One end of the first drain pipeline 13 communicates with the water storage space of the first water cup assembly 5, and the other end communicates with the washing pump 12. One end of the first water inlet pipeline 14 communicates with the washing pump 12, and the other end communicates with the first spray arm 7. It can be understood that a washing liquid is installed on the washing pump 12 to add the washing liquid to the water for cleaning. At the same time, the washing pump 12 is used to pump the recycled water to make the water flow cyclically.

[0061] According to an embodiment of the present utility model, the dishwasher further includes a main water inlet pipeline 11 and a water supply pipeline 15. The main water inlet pipeline 11 is arranged on the machine body 1, and the main water inlet pipeline 11 communicates with the second water cup assembly 6 to supply water to the second water cup assembly 6; one end of the water supply pipeline 15 communicates with the main water inlet pipeline 11, and the water supply pipeline 15 is located upstream of the second water cup assembly 6, and the other end of the water supply pipeline 15 communicates with the first spray arm 7.

[0062] The main water inlet pipeline 11 is connected to an external water source. In the main water inlet pipeline 11, a water supply pipeline 15 is connected upstream of the second water cup assembly 6. The water supply pipeline 15 can supply water to the first spray arm 7 before the water in the main water inlet pipeline 11 enters the second water cup assembly 6, so that it is not necessary to wait for the water in the second water cup assembly 6 to be full before supplying water to the first spray arm 7, effectively improving the use efficiency of the dishwasher.

[0063] According to an embodiment of the present utility model, the dishwasher further includes a water inlet valve 16. The water inlet valve 16 is arranged on the main water inlet pipeline 11, and the water supply pipeline 15 communicates with the main water inlet pipeline 11 through the water inlet valve 16.

[0064] It can be understood that the on-off of the main water inlet pipeline 11 and the water supply pipeline 15 can be controlled through the water inlet valve 16, so that the water inlet valve 16 can be timely opened when needed, and water is transported to the first spray arm 7 through the water supply pipeline 15. Since the first cavity 3 is located above the second cavity 4, in order to better adapt to the user's high-frequency and small-quantity washing with upper-layer washing, the water supply pipeline 15 can transport water to the first cavity 3 located in the upper layer. In this way, even if the user uses the first cavity 3 frequently, it is not necessary to frequently start the pump body. It can be understood that under the action of water pressure, the water in the water supply pipeline 15 can smoothly reach the first spray arm 7 without adding an additional pump body.

[0065] According to an embodiment of the present utility model, the dishwasher further includes a control valve 17. The downstream of the main water inlet pipeline 11 is sequentially connected to the second water cup assembly 6, the control valve 17, and the washing pump 12, and the first drainage pipeline 13 is connected to the washing pump 12 through the control valve 17. The dishwasher further includes a second water inlet pipeline 18 and a second drainage pipeline 19. One end of the second water inlet pipeline 18 is connected to the control valve 17, and the other end is connected to the second spray arm 8. One end of the second drainage pipeline 19 is connected to the second cavity 4, and the other end is connected to the second water cup assembly 6.

[0066] In this embodiment, the first water inlet pipeline 14 and the first drain pipeline 13 are connected to the control valve 17. The first water inlet pipeline 14 is specifically connected to the first spray arm 7 to supply water to the first cavity 3 in a cycle. Moreover, the second water inlet pipeline 18 and the second drain pipeline 19 are connected to the second water cup assembly 6 to supply water to the second cavity 4 in a cycle. Since the water discharged from the first cavity 3 through the first drain pipeline 13 does not pass through the second water cup assembly 6, that is, it does not mix with the water discharged from the second cavity 4 through the second drain pipeline 19 in the second water cup assembly 6, so as to avoid flavor cross - contamination. When in use, the control valve 17 can be used to control whether to supply water to the first cavity 3 or the second cavity 4 in a cycle as needed, so as to avoid the mixing of the circulating water of the first cavity 3 and the second cavity 4, and effectively prevent flavor cross - contamination of the water used.

[0067] In one embodiment, an installation space is provided inside the machine body 1. Components such as the main water inlet pipeline 11, the second water cup assembly 6, the control valve 17, the first water inlet pipeline 14, the first drain pipeline 13, the second water inlet pipeline 18 and the second drain pipeline 19 can be installed in the installation space. Exemplarily, the installation space is located at the bottom of the machine body 1, that is, the first cavity 3 and the second cavity 4 are located above the installation space, which is convenient for users to use. The first cavity 3 and the second cavity 4 can be distributed in an up - and - down structure, or in a left - and - right structure or other position structures, which is not limited herein.

[0068] It can be understood that water enters the first water inlet pipeline 14 from the main water inlet pipeline 11 through the control valve 17, then enters the first spray arm 7 from the first water inlet pipeline 14. The first spray arm 7 sprays water into the first cavity 3. The water in the first cavity 3 flows to the first water cup assembly 5 and is discharged from the first drain pipeline 13. The water discharged from the first drain pipeline 13 passes through the control valve 17 again. In this way, the water pipeline for the first cavity 3 is formed. In addition, water passes through the second water cup assembly 6 from the main water inlet pipeline 11 and enters the second water inlet pipeline 18 through the control valve 17, so as to enter the second cavity 4 through the second water inlet pipeline 18. The water in the second cavity 4 is then discharged from the second drain pipeline 19, and the water discharged from the second drain pipeline 19 returns to the second water cup assembly 6. In this way, the water pipeline for the second cavity 4 is formed.

[0069] In this embodiment, the user can choose to wash and dry a small amount of tableware in the first cavity 3, use a single cavity alone, which saves water, electricity and time. At the same time, by controlling the control valve 17 to only connect the first water inlet pipeline 14 and the first drain pipeline 13, the circulating water supply to the first cavity 3 is realized. At this time, the control valve 17 does not connect the second water cup assembly 6 and the second water inlet pipeline 18. In this way, the first cavity 3 realizes the drying and washing function, while the second cavity 4 realizes the storage function. Or, when washing lightly - oiled tableware in the first cavity 3 and washing non - tableware with heavy oil stains, such as a range hood filter, a wok, etc. in the second cavity 4, the control valve 17 can control the separate circulating water supply to the first cavity 3 and the second cavity 4, so as to separate the light oil stains and the heavy oil stains from each other without interference.

[0070] According to an embodiment of the present utility model, the dishwasher further includes a common pipeline 20. One end of the common pipeline 20 is connected to the control valve 17, and the other end is connected to a water distribution valve 21. The water distribution valve 21 is respectively connected to the first water inlet pipeline 14 and the second water inlet pipeline 18. The washing pump 12 is arranged in the common pipeline 20.

[0071] In this embodiment, the common pipeline 20 is connected downstream of the second water cup assembly 6 and the control valve 17. Water flows out from the second water cup assembly 6, passes through the control valve 17 and then flows out to the common pipeline 20. The common pipeline 20 is respectively connected to the first water inlet pipeline 14 and the second water inlet pipeline 18 through the water distribution valve 21. In this way, the water stored in the second water cup assembly 6 can be used by the first water inlet pipeline 14 and the second water inlet pipeline 18. At the same time, setting the common pipeline 20 is beneficial to reducing the complexity of the pipeline and saving the installation space. The water distribution valve 21 can control the water in the common pipeline 20 to flow to the first water inlet pipeline 14 or the second water inlet pipeline 18, or control the water supply to the first water inlet pipeline 14 and the second water inlet pipeline 18 simultaneously.

[0072] It can be understood that when only the first cavity 3 needs to be supplied with water, the common pipeline 20 is communicated with the first water inlet pipeline 14, and the control valve 17 is communicated with the first drainage pipeline 13 and the common pipeline 20. At this time, the passage between the control valve 17 and the second water cup assembly 6 can be closed to avoid the water discharged from the second cavity 4 into the second water cup assembly 6 from being mixed into the common pipeline 20. That is to say, when different functions need to be realized for the first cavity 3 and the second cavity 4, the water pipelines of the first cavity 3 and the second cavity 4 do not use the common pipeline 20 simultaneously to avoid the problem of flavor mixing.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present utility model do not depart from the spirit and scope of the technical solutions of the present utility model, and should all be covered within the scope of the claims of the present utility model.
