[0036] Due to the washing demand 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 in 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 during the lower-layer washing will also splash onto the upper-layer tableware along with the water flow. Therefore, whether the upper layer or the lower layer is selected for washing, 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.

[0037] The layer-by-layer washing only supports lower-layer washing and does not support upper-layer washing, which is contrary to the user's frequent and small-quantity washing requirement of using the upper layer (for small-quantity washing, using the upper layer can avoid bending over, and generally, the volume of the upper cavity is smaller than that of the lower cavity, which can reduce energy consumption and washing and drying time).

[0038] Moreover, since there is only one set of water return and filtration systems, 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 4, 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 non-tableware (heavily polluted) in the lower layer; washing baby and mother tableware in the upper layer and other tableware in the lower layer.

[0039] In view of the above problems, the following combines Figure 1 and Figure 2 to describe the dishwasher of the present application:

[0040] The dishwasher according to the first aspect embodiment of the present utility model includes a machine body 20, a main water inlet pipeline 3, a water storage component 4, a control valve 7, a first water inlet pipeline 8, a first drainage pipeline 9, a second water inlet pipeline 10, and a second drainage pipeline 11. The machine body 20 is provided with a mutually independent first cavity 1 and a second cavity 2; the main water inlet pipeline 3 is arranged on the machine body 20; the water storage component 4 is arranged on the machine body 20 and is connected to the water inlet pipeline; the control valve 7 is connected to the first water outlet of the water storage component 4; one end of the first water inlet pipeline 8 is connected to the control valve 7, and the other end is connected to the first cavity 1; one end of the first drainage pipeline 9 is connected to the first cavity 1, and the other end is connected to the control valve 7; one end of the second water inlet pipeline 10 is connected to the control valve 7, and the other end is connected to the second cavity 2; one end of the second drainage pipeline 11 is connected to the second cavity 2, and the other end is connected to the water storage component 4.

[0041] According to the dishwasher of the embodiment of the present utility model, the first cavity 1 and the second cavity 2 of the dishwasher are supplied with water through the main water inlet pipeline 3. The first cavity 1 and the second cavity 2 are independent of each other and can work independently. The first water inlet pipeline 8 and the first drain pipeline 9 are connected to the control valve 7 to supply water to the first cavity 1 in a circulating manner. Moreover, the second water inlet pipeline 10 and the second drain pipeline 11 are connected to the water storage component 4 to supply water to the second cavity 2 in a circulating manner. Since the water discharged from the first cavity 1 through the first drain pipeline 9 does not pass through the water storage component 4, that is, it does not mix with the water discharged from the second cavity 2 through the second drain pipeline 11 in the water storage component 4, so as to avoid odor mixing. When in use, the control valve 7 can be used to control whether to supply water to the first cavity 1 or the second cavity 2 in a circulating manner as needed, so as to avoid the mixing of the circulating water of the first cavity 1 and the second cavity 2, and can effectively prevent the odor mixing of the water used. It can be understood that the water storage component 4 is a water cup for storing the circulating water for timely use.

[0042] In an embodiment, an installation space is provided inside the machine body 20, and components such as the main water inlet pipeline 3, the water storage component 4, the control valve 7, the first water inlet pipeline 8, the first drain pipeline 9, the second water inlet pipeline 10 and the second drain pipeline 11 can be installed in the installation space. Exemplarily, the installation space is located at the bottom of the machine body 20, that is, the first cavity 1 and the second cavity 2 are located above the installation space for the convenience of the user. The first cavity 1 and the second cavity 2 can be distributed in an up-and-down structure, or in a left-and-right structure or other position structures, which are not limited herein.

[0043] It can be understood that the water used enters the first water inlet pipeline 8 from the main water inlet pipeline 3 through the control valve 7, and then enters the first cavity 1 from the first water inlet pipeline 8. The water in the first cavity 1 is discharged from the first drain pipeline 9, and the water discharged from the first drain pipeline 9 passes through the control valve 7 again. Thus, the water pipeline for the first cavity 1 is formed. In addition, the water used passes through the water storage component 4 from the main water inlet pipeline 3 and enters the second water inlet pipeline 10 through the control valve 7 to enter the second cavity 2 through the second water inlet pipeline 10. The water in the second cavity 2 is then discharged from the second drain pipeline 11, and the water discharged from the second drain pipeline 11 returns to the water storage component 4. Thus, the water pipeline for the second cavity 2 is formed.

[0044] In this embodiment, the user can choose to wash and dry a small amount of tableware in the first cavity 1, using a single cavity alone, which saves water, electricity and time. At the same time, the control valve 7 is controlled to only connect the first water inlet pipe 8 and the first drain pipe 9 to realize the circulating water supply to the first cavity 1. At this time, the control valve 7 does not connect the water storage component 4 and the second water inlet pipe 10. In this way, the first cavity 1 realizes the drying and washing function, while the second cavity 2 realizes the storage function. Or, when the first cavity 1 is used to clean lightly oiled tableware and the second cavity 2 is used to clean non-tableware with heavy oil stains, such as a range hood filter, a wok, etc., the control valve 7 can control the circulating water supply to the first cavity 1 and the second cavity 2 respectively, so as to separate the light oil stains and the heavy oil stains from each other without interference.

[0045] Exemplarily, when the first cavity 1 and the second cavity 2 need to achieve the same function, for example, when both are used to clean lightly oiled tableware, the control valve 7 can control to connect the first drain pipe 9 and the first water inlet pipe 8, and at the same time connect the water storage component 4 and the second water inlet pipe 10. In this way, the first cavity 1 and the second cavity 2 can achieve cleaning at the same time. Since both the first cavity 1 and the second cavity 2 are used to clean lightly oiled tableware, there is no need to worry about the problem of odor mixing.

[0046] It should be noted that the water outlet of the first water inlet pipe 8 is connected to the first spray arm in the first cavity 1, and the spraying and cleaning function is realized through the first spray arm. Similarly, the water outlet of the second water inlet pipe 10 is connected to the second spray arm in the second cavity 2, and the spraying and cleaning function is realized through the second spray arm.

[0047] According to an embodiment of the present invention, the dishwasher further includes a common pipeline 12. One end of the common pipeline 12 is connected to the control valve 7, and the other end is connected to a water distribution valve 13, and the water distribution valve 13 is respectively connected to the first water inlet pipe 8 and the second water inlet pipe 10.

[0048] In this embodiment, the common pipeline 12 is connected downstream of the water storage component 4 and the control valve 7. The water flows out from the water storage component 4, passes through the control valve 7 and then flows out to the common pipeline 12. The common pipeline 12 is respectively connected to the first water inlet pipe 8 and the second water inlet pipe 10 through the water distribution valve 13. In this way, the water stored in the water storage component 4 can be used by the first water inlet pipe 8 and the second water inlet pipe 10. At the same time, setting the common pipeline 12 is beneficial to reducing the complexity of the pipeline and saving the installation space. The water distribution valve 13 can control the water in the common pipeline 12 to flow to the first water inlet pipe 8 or the second water inlet pipe 10, or control the water supply to the first water inlet pipe 8 and the second water inlet pipe 10 at the same time.

[0049] It can be understood that when only the first cavity 1 needs to be supplied with water, the common pipeline 12 is connected to the first water inlet pipeline 8, and the control valve 7 is connected to the first drainage pipeline 9 and the common pipeline 12. At this time, the passage between the control valve 7 and the water storage component 4 can be closed to prevent the water discharged from the second cavity 2 into the water storage component 4 from mixing into the common pipeline 12. That is to say, when different functions need to be realized for the first cavity 1 and the second cavity 2, the water pipelines of the first cavity 1 and the second cavity 2 do not use the common pipeline 12 at the same time to avoid the problem of odor mixing.

[0050] According to an embodiment of the present invention, the control valve 7 is a three-way valve. One end of the control valve 7 is connected to the common pipeline 12, and the other end is selectively connected to the water storage component 4 and the first drainage pipeline 9. It can be understood that the three interfaces of the control valve 7 are respectively connected to the common pipeline 12, the water storage component 4 and the first drainage pipeline 9. The interface connected to the common pipeline 12 is used as the water outlet of the control valve 7, and the other two interfaces are the water inlets of the control valve 7. The control valve 7 can selectively open one of the water inlets to connect the water outlet of the water storage component 4 or the first drainage pipeline 9 to the common pipeline 12. In this embodiment, the water storage component 4 and the first drainage pipeline 9 are not connected to the common pipeline 12 at the same time to prevent the water discharged from the first cavity 1 and the second cavity 2 from mixing. Of course, in other embodiments, when the first cavity 1 and the second cavity 2 perform the same function and there is no need to worry about the problem of odor mixing, the water storage component 4 and the first drainage pipeline 9 can also be connected to the common pipeline 12 at the same time.

[0051] According to an embodiment of the present invention, a washing pump 14 is provided in the common pipeline 12, and the washing pump 14 is located upstream of the water distribution valve 13. It can be understood that the washing pump 14 is used to filter and discharge the sewage discharged from the first cavity 1 and the second cavity 2, so as to keep the water clean during the circulating cleaning process. Or, a washing liquid is installed on the washing pump 14 to add the washing liquid to the water for cleaning. At the same time, the washing pump 14 is used to pump the circulating water so that the water flows cyclically in the first cavity 1 and the second cavity 2 for flushing.

[0052] According to an embodiment of the present invention (not shown), the control valve 7 is a multi-way valve, and the control valve 7 is used to connect the water storage component 4 and the second water inlet pipeline 10, or the control valve 7 is used to connect the first drainage pipeline 9 and the first water inlet pipeline 8.

[0053] Exemplarily, the control valve 7 is a four-way valve. In this embodiment, in order to prevent the water in the first drainage pipeline 9 from mixing with the water in the second drainage pipeline 11, the control valve 7 can be provided with two independent passages. The first passage connects the water storage component 4 and the second water inlet pipeline 10, and the second passage connects the first drainage pipeline 9 and the first water inlet pipeline 8. In this way, two water flow passages are separately provided to prevent the water discharged from the first cavity 1 and the second cavity 2 from mixing and avoid the problem of odor mixing.

[0054] According to an embodiment of the present utility model, a filter element is provided inside the water storage component 4. The filter element is used to filter food residues and the like in the sewage. The filter element is an important part inside the dishwasher. Its main function is to filter out impurities and debris in the water, prevent these impurities from entering the spray head or water pump of the dishwasher, and thus avoid blockage. The design and material of the filter element usually include a metal mesh and filter cotton. These materials can effectively filter out food residues and large particles of dirt, and keep the water flow clean. Exemplarily, the filter system of the dishwasher usually consists of multiple parts, including a flat filter element, a lifting cup, a micro filter element, a water cup, etc. These components work together to ensure the efficient operation of the dishwasher and the cleanliness of the tableware. By filtering out food residues and other impurities, the filter element prevents large pieces of food residues from flowing into the drain pipe, thus avoiding the problem of pipe blockage. Optionally, for filtering the sewage generated after cleaning in the first cavity 1, a filter element, such as a filter net, filter cotton, etc., can be provided at the water inlet of the first drain pipe 9. In one embodiment, a water cup assembly can be provided at the water inlet end of the first drain pipe 9. That is, the sewage in the first cavity 1 flows into the water cup assembly under the action of gravity, and the water cup assembly communicates with the water inlet of the first drain pipe 9. In this way, a filter element can be provided in the water cup assembly for filtering.

[0055] According to an embodiment of the present utility model, the first cavity 1 is located above the second cavity 2. It can be understood that the first cavity 1 and the second cavity 2 are distributed in an up-and-down structure, which is convenient for users to use only the upper first cavity 1 for washing a small amount of tableware without bending down, and the volume of the upper first cavity 1 is generally smaller than that of the lower second cavity 2, which can reduce energy consumption and washing and drying time.

[0056] According to an embodiment of the present utility model, a water inlet solenoid valve 15 is provided at the water inlet of the main water inlet pipe 3; the water inlet solenoid valve 15 is connected to a motor. It can be understood that the water inlet solenoid valve 15 controls the inflow and outflow of water through the electromagnetic principle, so as to realize the automatic water inlet function. The excellent quality of the water inlet solenoid valve 15 ensures its efficiency, long service life, and high reliability. Optionally, the water inlet solenoid valve 15 is controlled by a smart socket. When the socket is turned on, the water valve will let water through; when the socket is turned off, the water valve will close. This control method enables the dishwasher to realize automatic water inlet, thus improving the convenience of use. In addition, the water flow in the dishwasher is heated by a heater, and the temperature can reach 60° - 80°. Such high-temperature water flow can effectively clean the tableware and ensure the washing effect.

[0057] In one embodiment, a breather 16 is provided on the main water inlet pipe 3, upstream of the water storage component 4; it can be understood that the breather 16 can prevent the water inside the dishwasher from flowing back: through its design, the breather 16 can effectively prevent the water inside the dishwasher from flowing back into the main water inlet pipe due to pressure changes or other reasons during the operation of the dishwasher, thereby maintaining the water circulation and pressure stability inside the dishwasher.

[0058] Optionally, the breather 16 can also be used for introducing hot air, diverting and temporarily storing the incoming water: the breather 16 is also responsible for introducing the hot air generated inside the dishwasher, while diverting and temporarily storing the water entering the dishwasher. This function helps to optimize the water usage efficiency and ensure the reasonable distribution and use of water during the washing process.

[0059] Optionally, the breather 16 can also be used for collecting and utilizing the condensate water: in some designs, the breather 16 also has a steam condensation function, which can condense the steam generated when the dishwasher inner tank is heated into water droplets, and collect these condensed water droplets through the water storage area inside the breather 16. These collected condensed water droplets are then used in the washing program of the dishwasher, thereby effectively improving the energy efficiency of the dishwasher.

[0060] Through its design functions, the breather 16 not only ensures the normal operation of the dishwasher, but also improves the energy usage efficiency, saving the user's electricity and water costs.

[0061] In one embodiment, a water softener 17 is provided on the main water inlet pipe 3, upstream of the water storage component 4.

[0062] When the dishwasher uses hard water (water containing a high concentration of calcium and magnesium ions) for washing, it will cause a series of problems. The calcium and magnesium ions in hard water will combine with the detergent during the washing process to form scale, which will not only affect the washing effect, but also clog components such as filters, water pipes, and spray arms, shortening the service life of the dishwasher. Therefore, it is necessary to use soft water for washing. The water softener 17 softens the water quality by adding dishwasher - specific salt and removing the calcium and magnesium ions in the water, thus solving the hard - water problem.

[0063] The use of the water softener 17 can not only improve the washing effect, making the tableware cleaner, but also reduce the formation of scale. The softened water combines better with the detergent, can more effectively remove stains, and at the same time avoids the problem of scale clogging the pipeline and spray arm, thereby protecting the dishwasher and extending its service life. In addition, the use of the water softener 17 can also reduce the amount of detergent used, as soft water combines more easily with the detergent, improving the washing efficiency.

[0064] According to an embodiment of the present utility model, the dishwasher further includes a main drainage pipeline 18, and the main drainage pipeline 18 is connected to the second water outlet of the water storage component 4.

[0065] It can be understood that a large amount of sewage will be generated after the water in the water storage component 4 is recycled. After a round of cleaning in the dishwasher, these sewage need to be discharged through the main drainage pipeline 18 to keep the inside of the dishwasher clean and hygienic. The main drainage pipeline is usually located at the rear of the dishwasher and is generally made of plastic or metal, and can be connected to the outdoor drainage pipeline. This design ensures that the sewage can be effectively discharged, avoiding the accumulation of sewage inside the dishwasher, thereby maintaining the normal operation of the dishwasher and the cleanliness of the internal environment.

[0066] According to an embodiment of the present utility model, a drainage pump 19 is provided on the main drainage pipeline 18. The design of the main drainage pipeline also takes into account safety and convenience. Its drainage is active drainage, with the support of the drainage pump 19, ensuring that the sewage will not flow back into the inside of the dishwasher, thereby protecting the internal parts of the dishwasher from being contaminated. This design not only extends the service life of the dishwasher and its components, but also improves the use efficiency and user satisfaction of the dishwasher. The drainage pipeline in the dishwasher is a key component to ensure the normal operation of the dishwasher and keep the inside clean. By effectively discharging the sewage, it provides a more hygienic and convenient tableware cleaning experience for users.

[0067] 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 by the scope of the claims of the present utility model.
