The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] Please also read Figure 1 and Figure 2 The present invention provides a dishwasher 10 for washing dishes, wherein the dishwasher 10 comprises a base 110, a cup 120, a plane filter plate 130, a filter element 140, a spray assembly 150 and a sewage discharge assembly 160. The base 110 provides a support foundation for the plane filter plate 130, the filter element 140, the spray assembly 150 and the sewage discharge assembly 160. The plane filter plate 130 and the filter element 140 are arranged in the base 110 and are respectively used for primary filtration and secondary filtration of washing wastewater after washing dishes. The cup 120 is connected to the plane filter plate 130 to facilitate the disassembly of the plane filter plate 130. The spray assembly 150 and the sewage discharge assembly 160 are both connected to the base 110. The spray assembly 150 is used to rinse the filter element 140 after washing. The sewage discharge assembly 160 is used to discharge the washing wastewater after rinsing the filter element 140.

[0034] Please also read Figure 4The base 110 is provided with a washing tank 111, a filter tank 113, a water collection tank 115, a first sewage outlet 117 and a second sewage outlet 118. The washing tank 111, the filter tank 113 and the water collection tank 115 are arranged and connected in sequence along the outflow direction of the water flow. The first sewage outlet 117 is connected to the water collection tank 115, and the second sewage outlet 118 is independently arranged outside the water collection tank 115 and is opened at the bottom of the filter tank 113. Usually, a water pipe is also connected to the water collection tank 115. When the dishwasher 10 is working, the bowls are accommodated in the washing tank 111, and the washing water input by the water pipe flows through the water collection tank 115 and the filter tank 113 into the washing tank 111 to wash the bowls. After the washing of the bowls is completed, the washing sewage in the washing tank 111 flows out from the washing tank 111 through the filter tank 113 to the water collection tank 115.

[0035] Please also read Figure 3 The cup 120 and the plane filter plate 130 are both accommodated in the washing tank 111, and the plane filter plate 130 can be detachably covered on the notch where the filter tank 113 and the washing tank 111 are connected, so as to filter the washing sewage once. Under the filtering action of the plane filter plate 130, the residue with large particle size in the washing sewage is retained in the washing tank 111, and can be cleaned out of the dishwasher 10 from the notch of the washing tank 111 after the dishwasher 10 finishes working; and the residue with large particle size in the washing sewage flows out of the filter tank 113 with the washing sewage through the mesh of the plane filter plate 130. A mounting port 131 is provided in the middle of the plane filter plate 130, and one end of the cup 120 passes through the mounting port 131 and is hooked on the side of the plane filter plate 130 facing the filter tank 113. By lifting the cup 120, the plane filter plate 130 can be synchronously driven to slide in the direction of the notch facing the washing tank 111, so as to disassemble the plane filter plate 130.

[0036] The filter element 140 is located on the water flow path from the washing tank 111 to the water collecting tank 115, and is connected to the notch of the water collecting tank 115 facing the filter tank 113. A filter cavity 141 connected to the water collecting tank 115 is formed in the filter element 140. A filter hole (not shown in the figure) connected to the filter cavity 140 is opened on the filter element 140. The filter hole is connected between the filter cavity 141 and the second sewage outlet 118, and the aperture of the filter hole is smaller than the aperture of the mesh on the flat filter plate 130. Specifically, the filter element 140 is accommodated in the filter tank 113 and cooperates with the gap between the tank wall of the filter tank 113. The washing sewage flowing through the mesh of the flat filter plate 130 can directly flow into the space between the filter element 140 and the tank wall of the filter tank 113, and the residue with larger particle size adheres to the outer cavity wall of the filter element 140, and the residue with smaller particle size flows out to the sump 115 along with the washing sewage through the filter holes on the filter element 140 and the filter cavity 141.

[0037] Please refer again Figure 1 and Figure 2 The spray assembly 150 includes a spray member 151, which is received in the filter cavity 141 and is rotatably arranged relative to the filter 140 around its own axis. Therefore, during the operation of the spray member 151, the spray direction of the spray member 151 can be changed to fully clean the inner cavity wall of the filter 140. At the same time, the cleaning water flow sprayed by the spray member 151 can also clear the filter holes to prevent the residues adhering to the outer cavity wall of the filter 140 from clogging the filter holes.

[0038] The sewage discharge component 160 includes a first sewage discharge component 161 and a second sewage discharge component 163. The first sewage discharge component 161 is connected to the first sewage discharge port 117 and communicates between the first sewage discharge port 117 and the outside. The residue on the inner cavity wall of the filter element 140 after flushing can be discharged to the outside through the first sewage discharge component 161. The second sewage discharge component 163 is connected to the second sewage discharge port 118 and communicates between the second sewage discharge port 118 and the outside. The residue on the outer cavity wall of the filter element 140 after dredging can be discharged to the outside through the second sewage discharge component 163. Therefore, by providing the spray component 150 and the sewage discharge component 160, the inner cavity wall and the outer cavity wall of the filter element 140 can be effectively cleaned, so that the filter element 140 has a better cleaning effect, thereby reducing the secondary pollution of the bowls and making the bowls have a better washing effect. Optionally, in this specific embodiment, the lifting cup 120 and the filter element 140 are both hollow cylindrical structures with openings at both ends, and a drainage channel 121 penetrating through the openings at both ends of the lifting cup 120 is formed in the lifting cup 120, and the filter cavity 141 penetrates through the openings at both ends of the filter element 140. One end of the filter element 140 abuts against one end of the lifting cup 120 that passes through the mounting opening 131 and is hooked on the side of the plane filter plate 130 facing the filter tank 113, so as to support the lifting cup 120. In addition, the filter cavity 141 of the filter element 140 is also connected with the drainage channel 121 of the lifting cup 120, and the washing sewage in the washing tank 111 can also flow directly into the sump 115 through the drainage channel 121 and the filter cavity 141, and be discharged to the outside of the dishwasher 10 under the action of the first drainage element 161.

[0039] Optionally, in this specific embodiment, the dishwasher 10 may not have a water pipe, and the spray assembly 150 not only has the function of cleaning the filter element 140, but also, before washing, the spray element 151 can also inject washing water for washing dishes into the washing tank 111 through spraying. The sewage discharge assembly 160 not only has the function of discharging the washing sewage after rinsing the filter element 140, but also can discharge the washing sewage after washing the dishes.

[0040] It should be noted that, in other embodiments, the dishwasher 10 may also have a water pipe, and the water path for the water pipe to transport washing water into the washing tank 111 is separated from the water path for the spray element 151 to transport cleaning water to the filter element 140 into the filter cavity 141.

[0041] Please also read Figure 5 , Figure 6 and Figure 7 The dishwasher 10 further includes a water inlet pipe 155 , which is connected between a water source and the spray element 151 . The spray element 151 rotates under the action of the water flow transported by the water inlet pipe 155 .

[0042] The water source inputs a cleaning water flow for cleaning the filter element 140 into the water inlet pipe 155. The spray element 151 rotates under the action of the cleaning water flow, and the spraying direction of the spray element 151 can be changed to clean the inner cavity wall of the filter element 140 along the circumference of the filter element 140 and dredge the filter holes.

[0043] By setting up the water inlet pipe 155, the spray member 151 can rotate under the action of the cleaning water flow, and the spray member 151 can be driven to rotate without using an additional driving member. This driving method is simple and easy, and can reduce the space occupied by the driving member, thereby facilitating the miniaturization and low cost of the dishwasher 10.

[0044] Optionally, in some embodiments, the water inlet pipe 155 may be a single one, or may be formed by a plurality of sub-water inlet pipes 1552 that are sequentially connected end to end and communicated.

[0045] In some embodiments, the spray assembly 150 also includes a spray pump 153, which has a water inlet and a water outlet. The water inlet is connected to a water source, and the water outlet is connected to the water inlet of the water inlet pipe 155. The spray element 151 is movably connected to the water outlet of the water inlet pipe 155.

[0046] Optionally, the spray pump 153 is fixed to the bottom of the notch of the base 110 facing away from the washing tank 111, the water inlet of the water inlet pipe 155 is connected to the water outlet of the spray pump 153, one end of the water inlet pipe 155 with the water outlet passes through the bottom of the water collecting tank 115 and extends into the water collecting tank 115, and the spray member 151 is movably connected to the water outlet of the water inlet pipe 155. The spray member 151 has a spray cavity connected to the water outlet, and a spray hole 1516 connected to the spray cavity is opened on the spray member 151, and the spray hole 1516 faces the inner cavity wall of the filter 140.

[0047] When the spray pump 153 pumps the cleaning water for cleaning the filter element 140 into the spray chamber through the water inlet pipe 155, the spray element 151 rotates around its own axis to clean the inner cavity wall of the filter element 140. At the same time, since the cleaning water has a large impact force, the filter holes can also be dredged.

[0048] By setting up the spray pump 153, the cleaning water flow injected into the spray element 151 can have a larger water pressure. The larger water pressure can drive the spray element 151 to rotate and ensure that the cleaning water flow sprayed from the spray element 151 has a larger range, so as to facilitate cleaning the inner cavity wall of the filter element 140 and dredge the filter holes.

[0049] In some embodiments, the spray pump 153, the water inlet pipe 155, the filter chamber 141 and the washing tank 111 together form a washing water path, the spray pump 153, the water inlet pipe 155, the filter chamber 141 and the first sewage outlet 117 together form a first washing water path for cleaning the inner cavity wall of the filter element 140, and the spray pump 153, the water inlet pipe 155, the filter chamber 141 and the second sewage outlet 118 together form a second washing water path for cleaning the outer cavity wall of the filter element 140. The washing water flowing through the washing water path can be used to clean dishes, the washing water flowing through the first washing water path can clean the inner cavity wall of the filter element 140 and discharge the residue to the outside of the dishwasher 10, and the washing water flowing through the second washing water path can clean the outer cavity wall of the filter element 140 and discharge the cleaned residue to the outside of the dishwasher 10.

[0050] The washing water circuit, the first rinse water circuit and the second rinse water circuit share the spray pump 153, the water inlet pipe 155 and the filter chamber 141. Compared with the washing water circuit, the first rinse water circuit and the second rinse water circuit being formed by using different components, the settings of the components forming each water circuit can be effectively simplified and reduced, so that the setting structure of the dishwasher 10 is simpler, the manufacturing cost is lower, and the size is more compact.

[0051] In some embodiments, the spray assembly 150 also includes a water inlet valve 157, which is connected to the water inlet pipe 155. The sewage assembly 160 also includes a sewage valve 167. The second sewage component 163 is a sewage pipe, and the sewage valve 167 is connected to the sewage pipe. The first sewage component 161 is a sewage pump. When the washing water circuit is opened, the spray pump 153 is started, the water inlet valve 167 is opened, and the sewage valve 167 and the sewage pump are closed.

[0052] When the dishes need to be washed, the spray pump 153 is started, the water inlet valve 167 is opened, the sewage valve 167 and the sewage pump are closed, and the washing water circuit is opened, and the washing water flow through the spray pump 153, the water inlet pipe 155, and the filter chamber 141 can flow into the washing tank 111 for washing the dishes. When the washing water flowing into the washing tank 111 meets the washing needs, the spray pump 153 and the water inlet valve 167 are closed to close the washing water circuit, and the dishwasher 10 starts the dishwashing operation.

[0053] By setting up the spray pump 153, the water inlet valve 157, the drain valve 167 and the drain pump, the on-off of the washing water circuit can be controlled to prevent the washing water from flowing out from the first drain port 117 and the second drain port 118 during the process of injecting the washing water into the washing tank 111, thereby causing waste of the washing water.

[0054] In some embodiments, when the first cleaning water circuit is opened, the spray pump 153 and the sewage pump are started, and the water inlet valve 157 is opened. When the second cleaning water circuit is opened, the spray pump 153 is started, and the water inlet valve 157 and the sewage valve 167 are opened.

[0055] When the filter element 140 needs to be cleaned, the spray pump 153 and the sewage pump are started, the water inlet valve 157 is opened, and the cleaning water flows through the spray pump 153, the water inlet pipe 155 and the filter cavity 141, and washes the inner cavity wall of the filter element 140. Then, the residue adhering to the inner cavity wall of the filter element 140 is mixed with the cleaning water flow to form cleaning sewage, which flows out into the sump 115 and is discharged to the outside of the dishwasher 10 under the action of the sewage pump. At the same time, the cleaning water flow can also clear the filter holes from the inside of the filter element 140, and flows into the groove wall of the filter groove 113 and the filter element 140 through the filter holes to wash the outer cavity wall of the filter element 140. Then, the residue adhering to the outer cavity wall of the filter element 140 is mixed with the cleaning water flow to form cleaning sewage, which is discharged to the outside of the dishwasher 10 through the sewage pipe 163.

[0056] It can be seen that the arrangement of the spray pump 153, the water inlet pipe 155, the sewage pump, the sewage pipe, the water inlet valve 157 and the sewage valve 167 can enable the dishwasher 10 to switch between different states, so as to make the dishwasher 10 more functional and intelligent. Moreover, the spray pump 153, the water inlet pipe 155, the sewage pump, the sewage pipe, the water inlet valve 157 and the sewage valve 167 cooperate to control the opening and closing of different waterways, so as to meet the requirements of the dishwasher 10 for different functions.

[0057] It should be noted that, in this specific embodiment, the dishwasher 10 also includes three sewage discharge paths. The washing tank 111, the flat filter plate 130, the filter tank 113, the filter hole, the filter chamber 141, the water collecting tank 115, the first sewage discharge port 117 and the sewage pump together form the first sewage discharge path; the washing tank 111, the flat filter plate 130, the filter tank 113, the second sewage discharge port 117 and the sewage pipe together form the second sewage discharge path; the washing tank 111, the sewage discharge channel 121, the filter chamber 141, the water collecting tank 115, the first sewage discharge port 117 and the sewage pump together form the third sewage discharge path. The washing sewage after the washing of the dishes can be discharged through any one, or any two or three sewage discharge paths.

[0058] In addition, it is worth mentioning that since the cup 120 and the filter element 140 are both hollow structures, when the washing sewage in the washing tank 111 directly enters the water collection tank 115 through the drainage channel 121 and the filter chamber 141 of the cup 120, the particle size of the residue carried in the washing sewage is relatively large. If the first sewage discharge member 161 does not have a large pressure to pull and discharge the residue during the sewage discharge process, it may cause the residue to accumulate in the water collection tank 115 and block the water collection tank 115. In this specific embodiment, since the first sewage discharge member 161 is a sewage pump, the large pressure of the sewage pump can pull the sewage and residue to the outside to ensure a better cleaning effect of the filter element 140. Since the residue flowing into the groove wall of the filter tank 113 and the filter element 140 has been filtered by the flat filter plate 130, the particle size of the residue at this position is relatively small, and it is less difficult to discharge. Under the influence of the washing sewage, the residue can be directly discharged to the outside of the dishwasher 10 through the sewage pipe. Compared with a sewage pump, the sewage pipe occupies a smaller volume and has a lower cost. It can be seen that by setting up the sewage pipe, the manufacturing cost of the dishwasher 10 can be effectively reduced while meeting the demand for sewage discharge outside the filter 140, and it is easy to achieve the miniaturization of the dishwasher 10. Optionally, the sewage pipe can be a single one, or it can be formed by connecting multiple sub-sewage pipes 1632 end to end and communicating with each other.

[0059] In some embodiments, the sewage discharge assembly 160 further includes a manifold 165, and the first sewage discharge member 161 and the second sewage discharge member 163 are both connected to the outside through the manifold 165. Specifically, the sewage pump has a sewage discharge end and a manifold end, the sewage discharge end is connected to the first sewage discharge port 117, and the manifold end is connected to the manifold 165, and the residue on the inner cavity wall of the filter element 140 can be discharged to the outside through the manifold 165. The opposite ends of the sewage discharge pipe are respectively connected to the second sewage discharge port 118 and the manifold 165, and the residue on the outer cavity wall of the filter element 140 can be discharged to the outside through the manifold 165.

[0060] By setting up the conduit 165, the sewage flowing through the sewage pump and the sewage pipe can be converged and discharged from the same pipe. Therefore, during the installation of the dishwasher 10, only a structure that can be connected to the conduit 165 and used to receive cleaning sewage and washing sewage is installed on the outside, so as to simplify the installation difficulty of the dishwasher 10.

[0061] In some embodiments, the bottom protrusion of the filter tank 113 forms a water retaining rib 119 , and the water retaining rib 119 is used to retain the sewage flowing into the filter tank 113 within the filter tank 113 .

[0062] In order to prevent the washing sewage flowing into the filter tank 113 from the washing tank 111 or the washing sewage flowing into the filter tank 113 from the filter cavity 141 through the filter hole from overflowing to other positions of the base 110 and polluting the internal structure of the dishwasher 10, a water retaining rib 119 is also provided at the bottom of the filter tank 113. The water retaining rib 119 can block the washing sewage or cleaning sewage between the outer side of the filter element 140 and the tank wall of the filter tank 113 in the filter tank 113, and ensure that the washing sewage or cleaning sewage is effectively discharged from the second sewage outlet 118, thereby effectively improving the reliability of the cleaning of the filter element 140.

[0063] In some embodiments, the spray element 151 includes a hollow spray body 1512 and multiple spray arms 1514. The multiple spray arms 1514 are arranged at intervals along the circumference of the spray body 1512 and are connected to the spray body 1512. The spray body 1512 is connected to the water inlet pipe 155, and a spray hole 1516 is opened on the spray arm 1514.

[0064] The spray body 1512 and each spray arm 1514 are hollow structures. Multiple spray arms 1514 are arranged at intervals along the circumference of the spray body 1512, and are connected and communicated with the spray body 1512 to form a spray chamber. Each spray arm 1514 is provided with a spray hole 1516, and one end of the spray body 1512 is communicated with the water inlet pipe 155. Driven by the water flow, the spray body 1512 and the spray arm 1514 rotate synchronously, and during the rotation of each spray arm 1514, the direction of the water flow sprayed from the spray arm 1514 changes to wash the inner cavity wall of the filter element 140 and dredge the filter holes. The arrangement of multiple spray arms 1514 increases the spray area of ​​the spray element 151 per unit time, so that the filter element 140 has a better cleaning effect.

[0065] In some embodiments, each spray arm 1514 extends radially along the filter element 140, and a plurality of spray holes 1516 are provided on the spray arm 1514 and are spaced apart along the length direction of the spray arm 1514. Therefore, the spray element 151 sprays more water per unit time and has a wider spray range, so that the cleaning effect of the inside and outside of the filter element 140 is better.

[0066] In some embodiments, the angles formed between the axis of the spray hole 1516 on each spray arm 1514 and the axis of the filter element 140 are different. Therefore, each spray arm 1514 can spray the filter element 140 at multiple angles during the rotation process to avoid the spray element 151 having a dead angle in the spray.

[0067] It should be noted that, in some other embodiments, the spray member 151 may also be tubular, and the lumen of the spray member 151 is the spray chamber, and the spray holes 1516 are arranged at intervals along the circumference of the spray member 151 and communicated with the lumen.

[0068] Please also read Figure 8 and Fig. 9 In some embodiments, the dishwasher 10 further includes a scrubbing member 170 , which is coupled to the spray body 1512 and rotates synchronously with the spray member 151 . The scrubbing member 170 is used to scrub the inner cavity wall of the filter element 140 .

[0069] Specifically, the brushing member 170 is accommodated in the filter cavity 141, and in the process of synchronously rotating with the spraying member 151, the brushing member 170 can brush the inner cavity wall of the filter 140. Under the joint action of the brushing member 170 and the spraying member 151, the residue on the inner cavity wall of the filter 140 is more easily separated from the filter 140. At the same time, the bristles on the brushing member 170 can also dredge the filter holes from the inner side of the filter 140 to prevent the filter holes from being blocked. It can be seen that by setting the brushing member 170, the filter 140 has a better cleaning effect.

[0070] In some embodiments, the brushing member 170 is detachably mounted on the spray body 1512. Optionally, the brushing member 170 can be detachably connected through the cooperation of the adsorption member 180 and the matching member that can generate magnetic force, or the cooperation of the limiting column and the limiting hole, etc. In this specific embodiment, the brushing member 170 is detachably fixed to the spray body 1512 through the adsorption member 180. The adsorption member 180 is a magnet, and at least the part of the brushing member 170 adsorbed on the magnet can be a metal structure, or a matching member is installed on the brushing member 170 to achieve the detachable installation of the spray member 151 and the brushing member 170.

[0071] In some embodiments, a slot 1518 is provided on the spray body 1512, and the slot wall of the slot 1518 protrudes to form a plurality of anti-foolproof ribs 1519, and the side wall of one end of the brush member 170 is recessed to form a plurality of anti-foolproof grooves 171 arranged at intervals along the circumference of the brush member 170. When the plurality of anti-foolproof grooves 171 correspond one-to-one to the plurality of anti-foolproof ribs 1519 and are held together, the projections of the spray arm 1514 and the brush member 170 in the plane where the slot 1518 is located are completely misplaced.

[0072] On the one hand, the corresponding foolproof ribs 1519 cooperate with the foolproof grooves 171 to further limit and fix the brushing member 170, so that the installation of the spraying member 151 and the brushing member 170 is more secure. On the other hand, when the multiple foolproof grooves 171 correspond to each other and are clamped with the multiple foolproof ribs 1519, the projections of the spraying arm 1514 and the brushing member 170 in the plane where the slots 1518 are located are completely misaligned. Therefore, when the brushing member 170 is installed on the spraying member 151, during the spraying process, the brushing member 170 does not block the cleaning water flow sprayed from the spray hole 1516, and the cleaning water flow can maintain its larger spray stroke, so that the filter 140 has a better cleaning effect.

[0073] In this specific embodiment, the scrubbing member 170 includes a scrubbing body 173 and a brush head 175. The scrubbing body 173 is a columnar metal component, and the brush head 175 is flat and mounted on one end of the scrubbing body 173 and located on one side of the scrubbing body 173. The end of the brush head 175 away from the scrubbing body 173 can be used for scrubbing. The adsorbent 180 is fixed to the bottom of the card slot 1518, and the end of the scrubbing body 173 away from the brush head 175 extends into the card slot 1518 and is adsorbed and fixed to the adsorbent 180. A plurality of foolproof grooves 171 are formed on the peripheral arm of the end of the scrubbing body 173 away from the brush head 175.

[0074] The working process of the entire dishwasher 10 is explained below through a specific description.

[0075] Before washing, the drain valve 167 is closed, the drain pump stops working, the water inlet valve 157 is opened, the spray pump 153 works, and the washing water flows through the washing water path into the washing tank 111. When the water volume reaches the preset value that can be used to wash the dishes, the water inlet valve 157 is closed, the spray pump 153 stops working, and the dishwasher 10 starts to wash the dishes. When the dishes are washed, the drain valve 167 and the drain pump are opened, and the washing sewage is discharged to the outside of the dishwasher 10 through one of the sewage drainage paths, or any two sewage drainage paths, or three sewage drainage paths. After the washing sewage is discharged, the water inlet valve 157 is opened again, the spray pump 153 is restarted, the drain valve 167 and the drain pump remain in the open state, and the washing water flows through the first washing water path and the second washing water path to wash the filter element 140. After the washing is completed, the entire working process of the dishwasher 10 is completed, the drain valve 167 and the water inlet valve 157 are closed, and the sewage pump and the spray pump 153 stop working.

[0076] In the above-mentioned dishwasher 10, the spray component 151 is accommodated in the filter cavity 141 and rotates around its own axis relative to the filter 140. The spray direction of the spray component 151 can be adjusted to fully clean the inner cavity wall of the filter 140. Then, the residue on the inner cavity wall of the filter 140 after washing can be discharged to the outside through the first sewage discharge component 161. In addition, the spray component 151 can also dredge the filter holes, and the residue on the outer cavity wall of the filter 140 after dredging can be discharged to the outside through the second sewage discharge component 163. Therefore, by providing the spray component 150 and the sewage discharge component, the inner cavity wall and the outer cavity wall of the filter 140 can be effectively cleaned, so that the filter 140 has a better cleaning effect, thereby reducing the secondary pollution of the bowls, and making the bowls have a better washing effect.
