Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a slag collecting and filtering device and a dishwasher. Background Art

[0002] Dishwashers use internally circulated water to wash dishes using a jet flow, reducing water consumption. During the wash cycle, food debris enters the water and is filtered through a filter. As food debris accumulates, the pores in the filter gradually become clogged with large particles, reducing the water flow through the pump. This reduces the strength of the water jet flow and results in incomplete washing. To ensure optimal dishwashing performance, users must regularly clean the filter.

[0003] In existing internal circulation systems, debris is constantly washed away by the circulating water. Small particles of debris can enter the wash water and be carried onto dishes, causing secondary contamination. To ensure optimal dishwashing performance, several solutions are commonly used: 1) increasing the filter area to reduce the frequency of filter cleaning; 2) using a scraper to clean the side of the filter where debris accumulates.

[0004] However, increasing the filter area increases the cost of the filter. During cleaning, the scraper squeezes out debris, which then passes through the filter and into the water pump, causing secondary pollution, affecting the cleaning effect, affecting the filter's performance and lifespan, and increasing secondary pollution, affecting the cleaning effect. Furthermore, debris adheres to the filter, making it difficult to remove. Utility Model Content

[0039] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] like Figures 1 to 10 The utility model provides a residue collection and filtering device 10, which can be used in a dishwasher. The residue collection and filtering device 10 includes a water collection chamber 101, a filter chamber 102, and a residue collection chamber 103. The water collection chamber 101 is used to collect wash water, the filter chamber 102 is used to separate residue from water in the wash water, and the residue collection chamber 103 is used to collect residue separated by the filter chamber 102.

[0041] Specifically, during the operation of the dishwasher, the circulating pump 12 can drive the washing water from the residue collecting and filtering device 10 to the spray arm and other components for washing tableware, and use the washing water to wash the tableware, etc.; then the washing water flows into the residue collecting and filtering device 10 and converges into the water collecting chamber 101; then the washing water in the water collecting chamber 101 is passed into the filter chamber 102, and the washing water entering the filter chamber 102 is separated from the residue; most of the separated water will be passed into the circulating pump 12, and pumped to the spray arm and other components for washing tableware by the circulating pump 12, and the separated residue will flow into the residue collecting chamber 103.

[0042] According to the embodiment of the present invention, the slag collection and filtering device 10 can filter the washing water through the filter chamber 102 and collect slag using the slag collection chamber 103. The slag can be retained in the slag collection chamber 103, which facilitates the collection of slag during the washing process and prevents the slag from remaining in the filter chamber 102 and affecting the separation of slag and water in the washing water in the filter chamber 102, thereby improving the filtering effect of the slag collection and filtering device 10. In addition, after the slag is collected by the slag collection chamber 103, the slag can be discharged manually or automatically. Since the slag is relatively concentrated, the slag discharge can be convenient.

[0043] like Figure 3 and Figure 10 The filter chamber 102 may have a first inlet 1021 and a first outlet 1022. The first inlet 1021 is connected to the water collection chamber 101, and the first outlet 1022 is used to discharge the separated water. The filter chamber 102 is provided with a first filter screen 163. The first inlet 1021 and the second inlet 1031 are located on one side of the first filter screen 163, and the first outlet 1022 is located on the other side of the first filter screen 163. Specifically, wash water enters the filter chamber 102 through the first inlet 1021, flows through the first filter screen 163 to the first outlet 1022, and is finally pumped for washing dishes, etc. The residue in the wash water will be sent out of the filter chamber 102 through the second inlet 1031 and flow into the residue collection chamber 103, so that the residue is separated by the residue collection chamber 103. This facilitates the separation of slag and water in the filter chamber 102, improves the filtration efficiency and filtration effect of the filter chamber 102, and prevents the first filter screen 163 from being blocked, thereby improving the stability of the slag collection and filtration device 10. Of course, the first filter screen 163 in the present invention can also be arranged outside the filter chamber 102.

[0044] The slag collecting chamber 103 may have a second inlet 1031, a second outlet 1032, and a slag discharge port 1033. The second inlet 1031 communicates with the filter chamber 102, the second outlet 1032 is used for draining water, and the slag discharge port 1033 is used for discharging slag. The slag collecting chamber 103 is provided with a second filter screen 164. The second inlet 1031 and the slag discharge port 1033 are located on one side of the second filter screen 164, and the second outlet 1032 is located on the other side of the second filter screen 164. Specifically, the slag and some water separated by the filter chamber 102 are introduced into the slag collecting chamber 103 through the second inlet 1031. Under the filtering effect of the second filter screen 164, the water is discharged from the second outlet 1032 and driven by the circulation pump 12 to the dishwashing component. The remaining slag after filtration remains in the slag collecting chamber 103 and can be discharged through the slag discharge port 1033. The slag collecting chamber 103 can separate the water and debris entering the slag collecting chamber 103. Therefore, some of the water in the filter chamber 102 can flow into the slag collecting chamber 103, and the water flow can carry the debris in the filter chamber 102 into the slag collecting chamber 103, so that the slag collecting chamber 103 can collect the residue. In addition, the water entering the slag collecting chamber 103 is filtered and then discharged, which can prevent the slag-water mixture in the slag collecting chamber 103 from flowing back into the filter chamber 102. Of course, the second filter screen 164 in the present invention can also be installed outside the slag collecting chamber 103.

[0045] In addition, the slag collecting and filtering device 10 further includes a circulation pump 12 and a drainage pump 13 , wherein the circulation pump 12 is connected to the first outlet 1022 and the second outlet 1032 ; the drainage pump 13 is connected to the slag discharge port 1033 .

[0046] like Figures 3 to 10 In some embodiments, the water collection chamber 101 and the filter chamber 102 are arranged side by side, and the first inlet 1021 is provided between the water collection chamber 101 and the filter chamber 102. This facilitates the flow of wash water in the water collection chamber 101 into the filter chamber 102, thereby improving the filtration efficiency and filtration flow rate of the residue collection and filtration device 10, thereby meeting the pumping requirements of the circulation pump 12 and the washing water demand of the dishwasher.

[0047] Optionally, a vent 1023 is further provided between the water collecting chamber 101 and the filter chamber 102. The vent 1023 is connected to the external space of the slag collecting filter device 10 to balance the internal and external air pressures of the filter chamber 102, wherein the vent 1023 can be provided at the upper end of the peripheral wall of the filter chamber 102. This facilitates the discharge of washing water into the filter chamber 102, facilitates the filtration of washing water through the slag collecting filter device 10, and effectively improves the efficiency and effect of filtration. In addition, the vent 1023 is higher than the first inlet 1021 and / or the vent 1023 is not lower than the second inlet 1031, which can reduce the possibility of the vent 1023 being blocked.

[0048] In some embodiments, the filter chamber 102 and the slag collecting chamber 103 are arranged side by side, and the second inlet 1031 is provided between the filter chamber 102 and the slag collecting chamber 103. This facilitates the flow of washing water with residue in the filter chamber 102 into the slag collecting chamber 103, thereby improving the filtration efficiency and effect of the slag collecting filter device 10.

[0049] Optionally, the second inlet 1031 is higher than the bottom of the filter chamber 102 and the bottom of the slag chamber 103. This can prevent the fluid in the filter chamber 102 from flowing into the slag chamber 103 without resistance, and most of the washing water will be filtered in the filter chamber 102. The amount of washing water entering the slag chamber 103 is small, which reduces the impact on the residue in the slag chamber 103. In addition, it can also prevent the residue in the slag chamber 103 from flowing back. In addition, when the slag filtering device 10 is filtering, the other positions of the slag chamber 103 except the second inlet 1031 and the second outlet 1032 are closed, which can facilitate the formation of a relatively high-pressure environment in the slag chamber 103, so as to reduce the water entering the slag chamber 103, and achieve the retention of residue in the slag chamber 103, thereby improving the filtration efficiency and effect of the slag filtering device 10.

[0050] In some embodiments, the slag collection and filtering device 10 further includes a drainage chamber 104, which is disposed below the water collection chamber 101 and connects the water collection chamber 101 to the slag discharge port 1033. The drainage pump 13 is connected to the drainage chamber 104. The drainage chamber 104 can be used to discharge residue, facilitating automatic slag discharge of the slag collection and filtering device 10. Specifically, during use, washing water flows into the slag collecting chamber 103, wherein water enters the filter chamber 102 from the first inlet 1021, and after filtration, most of the water passes through the first filter screen 163 and flows into the first outlet 1022, and a small amount of water flows into the slag collecting chamber 103, and flows into the second outlet 1032 after passing through the second filter screen 164; part of the residue flows from the water collecting chamber 101 into the drainage chamber 104, and part of the residue enters the filter chamber 102 from the water collecting chamber 101, flows into the first outlet 1022 after filtration, and enters the slag collecting chamber 103, and remains in the slag collecting chamber 103 after passing through the second filter screen 164. When discharging slag or draining water, the residue in the slag collecting chamber 103 enters the drainage chamber 104 and is discharged from the slag collecting filter device 10 together with the residue in the drainage chamber 104.

[0051] Optionally, the slag discharge port 1033 is provided with a one-way valve 17. When the one-way valve 17 is open, the slag discharge port 1033 is connected to the drainage chamber 104. The one-way valve 17 is configured to open the slag discharge port 1033 in one direction along the slag discharge direction of the slag collection chamber 103. In addition, the slag discharge port 1033 can be connected to the drainage pump 13. During the filtration process, the drainage pump 13 is turned off, the air pressure at the drainage pump 13 inlet is relatively high, the air pressure in the slag collection chamber 103 is relatively low, and the one-way valve 17 is in a closed state. During the slag discharge process, the drainage pump 13 is running, the air pressure at the drainage pump 13 inlet is relatively low, and the air pressure in the slag collection chamber 103 is relatively high. The one-way valve 17 is in an open state, thereby facilitating the discharge of residue in the slag collection chamber 103.

[0052] The aforementioned one-way valve 17 may include a cover plate, a rubber cover, a bracket, and a third sealing ring, primarily to open and close the slag discharge port 1033. The bracket serves as a support, assembled with the slag discharge port 1033 and sealed via the sealing ring. The bracket may have an opening, and the rubber cover may be connected to the bracket and configured to rotate to open and close the opening. The portion of the rubber cover opposite the opening is provided with a cover plate to support the rubber cover and enhance its sealing effect when closing the opening. The one-way valve 17 is used to open and close the slag discharge port 1033.

[0053] In some embodiments, the water collection chamber 101 is provided with a filter cup 162. The filter cup 162 has a first filter portion on its peripheral wall and a second filter portion on its bottom wall. The first filter portion filters the wash water flowing from the water collection chamber 101 to the filter chamber 102, while the second filter portion filters the wash water flowing from the water collection chamber 101 to the drain chamber 104. This facilitates the discharge of residue. Optionally, the mesh size of the first filter portion is larger than the mesh size of the second filter portion.

[0054] In some embodiments of the present invention, the water collection chamber 101, the filter chamber 102, and the residue collection chamber 103 are arranged side by side, with the water collection chamber 101 adjacent to the filter chamber 102, the filter chamber 102 adjacent to the residue collection chamber 103, and the residue collection chamber 103 adjacent to the water collection chamber 101. This facilitates the flow of water and residue, making it easier to filter the washing water and collect the residue.

[0055] like Figure 1 and Figure 2In some embodiments, the residue collection and filtering device 10 further includes: a flat filter screen 161, the flat filter screen 161 having an installation opening, and the flat filter screen 161 is configured to be inclined downward from the periphery to the installation opening, and the upper end of the water collection chamber 101 is provided with a water collection opening and is opposite to the installation opening; and a filter cup 162, the filter cup 162 being inserted through the installation opening and the water collection chamber 101. The flat filter screen 161 and the filter cup 162 can be used to filter the washing water once, further improving the filtering effect of the washing water. In addition, the filter cup 162 can retain larger residues, and the residue collection component can be cleaned by removing the filter screen. The filter screens (first filter screen 163, second filter screen 164, and filter cup 162) in the present invention can be configured as an easy-to-assemble and disassemble structure, and can all be removed from the inside of the cleaning chamber to facilitate later maintenance.

[0056] Optionally, a positioning portion is provided at the lower end of the water collecting chamber 101, and the lower end of the filter cup 162 is detachably fastened to the positioning portion, so as to facilitate filtering and removal of the filter cup 162, so as to facilitate primary filtration and the disposal of larger residues.

[0057] In some embodiments, the residue collection and filtration device 10 includes a water cup 11, with a water collection chamber 101, a filter chamber 102, and a residue collection chamber 103 disposed within the water cup 11. This can improve the integration of the residue collection and filtration device 10, simplify the residue collection and filtration device 10, and enhance the stability of the dishwasher. Of course, the water collection chamber 101, the filter chamber 102, and the residue collection chamber 103 in the present invention can also be configured as separate structures.

[0058] Optionally, the water cup 11 includes a cup body 111 and a flow channel plate 112. The filter cavity 102 and the slag collection cavity 103 are provided in the cup body 111, and the flow channel plate 112 covers the bottom of the cup body 111. This can simplify the structure of the slag collection filter device 10 and improve the filtering efficiency and effect of the slag collection filter device 10.

[0059] The water cup 11 comprises a water collection chamber 101, a filter chamber 102, a slag collection chamber 103, a drainage chamber 104, and a diversion chamber. The slag collection chamber 103 communicates with the water collection chamber 101 via a slag discharge port 1033, which is equipped with a one-way valve 17. During cleaning, the one-way valve 17 is closed, separating the water collection chamber 101 from the slag collection chamber 103. During drainage, the one-way valve 17 opens, connecting the water collection chamber 101 with the slag collection chamber 103. The water cup 11 primarily performs functions such as backwater collection, backwash filtration, slag collection, spray arm flow switching, and water and slag removal.

[0060] The flow plate 112 of the present invention serves as the bottom wall of the filter chamber 102 and the slag collection chamber 103, and is used to position the first filter screen 163 and the second filter screen 164. Furthermore, a flushing channel is provided within the flow plate 112, which communicates with the flushing device 1124 and is connected to the circulation pump 12. A transmission chamber 1123 is also provided within the flow plate 112, and the transmission assembly 15 is disposed within the transmission chamber 1123. Specifically, the first gear 151, the second gear 152, and the third gear 153 are disposed within the transmission chamber 1123. The flow plate 112 of the present invention includes, but is not limited to, the following embodiments and their combinations.

[0061] Example 1

[0062] The first outlet 1022 and the second outlet 1032 are provided on the flow channel plate 112. The flow channel plate 112 is further provided with a pump flow channel 1121 connecting the first outlet 1022 and the second outlet 1032. The pump flow channel 1121 is connected to the inlet of the circulation pump 12. During use, the circulation pump 12 can create a negative pressure downstream of the first filter screen 163 and downstream of the second filter screen 164, so that the washing water can flow to the pump flow channel 1121, thereby facilitating the use of the slag collection and filtering device 10.

[0063] Example 2

[0064] A filter chamber cover 1632 is provided at the upper end of the filter chamber 102 . The upper end of the first filter screen 163 is rotatably connected to the filter chamber cover 1632 , and the lower end is rotatably connected to the flow channel plate 112 .

[0065] First filter 163 is rotatably mounted within filter chamber 102. The rotation of first filter 163 allows for surface cleaning of the filter, thereby maintaining the filtration performance of first filter 163. Furthermore, a flushing device 1124 can be provided, positioned to cover first filter 163 along its axis. Rotating first filter 163 allows for comprehensive flushing of first filter 163, improving the efficiency and effectiveness of surface cleaning. Furthermore, the centrifugal force generated by the rotation of first filter 163 separates debris adhering to its surface from first filter 163; the relative motion between first filter 163 and the water also separates any surface debris from first filter 163.

[0066] In some examples, the first filter screen 163 can be configured to rotate freely. That is, the first filter screen 163 can be configured to rotate under the driving action of the water flow, which can simplify the structure of the slag collection and filtering device 10 and facilitate the surface cleaning of the first filter screen 163 during the filtering process.

[0067] like Figure 4 and Figure 8The upper end of the filter chamber 102 is provided with an opening and a filter chamber cover 1632. The filter chamber cover 1632 is used to open and close the filter chamber 102. The aforementioned first filter screen 163 is connected to the filter chamber cover 1632. This facilitates the assembly and maintenance of the centrifugal assembly and improves the assembly efficiency of the centrifugal assembly. The filter chamber cover 1632 can be quickly assembled. Optionally, the filter chamber cover 1632 is detachably connected to the filter chamber 102. This facilitates the rapid assembly and disassembly of the filter chamber cover 1632, improves the stability of the centrifugal assembly, and allows for easy inspection of the status within the filter chamber 102, facilitating cleaning of the centrifugal assembly.

[0068] Optionally, a first groove is provided on the circumferential surface of the filter chamber cover 1632. A first sealing ring 1633 is provided along the circumference of the filter chamber cover 1632 and engages with the first groove. The first sealing ring 1633 seals the gap between the filter chamber cover 1632 and the inner circumferential surface of the filter chamber 102. Furthermore, the filter chamber cover 1632 is provided with a bearing. The upper end of the first filter screen 163 is connected to the bearing, and the bearing is used to achieve a rotational connection between the first filter screen 163 and the filter chamber cover 1632. The upper end of the first filter screen 163 is rotatably connected to the filter chamber cover 1632.

[0069] Example 3

[0070] like Figure 4 and Figure 8 The upper end of the slag collecting chamber 103 is provided with a slag collecting chamber cover 1642, the upper end of the second filter screen 164 is rotatably connected to the slag collecting chamber cover 1642, and the lower end is rotatably connected to the flow channel plate 112;

[0071] The second filter screen 164 is rotatably mounted within the slag collecting chamber 103. The rotation of the second filter screen 164 cleans the filter screen surface to maintain the filtering performance of the second filter screen 164. The centrifugal force generated by the rotation of the second filter screen 164 separates the residue adhering to the surface from the second filter screen 164. The relative motion between the second filter screen 164 and the water also separates the residue adhering to the surface from the second filter screen 164.

[0072] In some examples, the second filter screen 164 can be configured to rotate freely. In other words, the second filter screen 164 can be configured to rotate under the driving force of the water flow, which can simplify the structure of the slag collection and filtering device 10 and facilitate the surface cleaning of the second filter screen 164 during the filtering process.

[0073] like Figure 4 and Figure 8 The upper end of the slag collecting chamber 103 is provided with an opening, and the upper end of the slag collecting chamber 103 is provided with a slag collecting chamber cover 1642 for opening and closing the slag collecting chamber 103. This can facilitate the assembly and maintenance of the slag collecting and filtering device 10 and improve the assembly efficiency of the slag collecting and filtering device 10.

[0074] The second filter screen 164 is connected to the slag chamber cover 1642, enabling quick assembly of the slag chamber cover 1642 and the second filter screen 164. Optionally, the slag chamber cover 1642 is detachably connected to the slag chamber 103. This facilitates quick assembly and disassembly of the slag chamber cover 1642, improves the stability of the slag filtering device 10, and allows for easy inspection of the status of the slag chamber 103, facilitating cleaning of the slag filtering device 10.

[0075] Optionally, a second groove is provided on the circumferential surface of the slag chamber cover 1642. A second sealing ring 1643 is disposed along the circumference of the slag chamber cover 1642 and engages with the groove. The second sealing ring 1643 seals the gap between the slag chamber cover 1642 and the inner circumferential surface of the slag chamber 103. Furthermore, the slag chamber cover 1642 is provided with a bearing, to which the upper end of the second filter screen 164 is connected, thereby achieving a rotational connection between the second filter screen 164 and the slag chamber cover 1642. The upper end of the second filter screen 164 is rotationally connected to the slag chamber cover 1642, while the lower end of the second filter screen 164 is rotationally connected to the bottom wall of the slag chamber 103. The upper end of the second filter screen 164 is rotationally connected to the slag chamber cover 1642.

[0076] Example 4

[0077] like Figure 4 and Figure 8 The flow channel plate 112 is provided with a flushing device 1124, which extends into the filter chamber 102 for flushing the first filter screen 163. The flow channel plate 112 is also provided with a backwash flow channel 1122, which is connected to the flushing device 1124, and the backwash flow channel 1122 is configured to connect to the outlet of the washing circulation pump 12.

[0078] The flushing device 1124 is configured to spray water toward the first filter screen 163 to flush the first filter screen 163. The flushing device 1124 can clean the surface of the first filter screen 163 to maintain the filtering performance of the first filter screen 163.

[0079] Optionally, the flushing device 1124 can be located downstream of the first filter screen 163 and spray water toward the first filter screen 163. This allows for reverse flushing of the first filter screen 163, thereby improving the cleaning effect of the first filter screen 163. Of course, the flushing device 1124 can also be located upstream of the first filter screen 163 and spray water toward the first filter screen 163, which can also achieve cleaning of the first filter screen 163.

[0080] Furthermore, if Figure 8First filter screen 163 is cylindrical in shape, and the peripheral wall of first filter screen 163 is used to separate residue and water in the wash water. The inner space of first filter screen 163 is connected to first outlet 1022, and the outer space of first filter screen 163 is connected to first inlet 1021 and second inlet 1031. Flushing device 1124 includes at least one backwash spray arm disposed inside first filter screen 163 and spraying water toward the peripheral wall of first filter screen 163. When first filter screen 163 is filtering, wash water can flow from the outer space of first filter screen 163 to the inner space of first filter screen 163 and be filtered by the peripheral wall of first filter screen 163. The outer space of first filter screen 163 is configured as the upstream of first filter screen 163, and the inner space of first filter screen 163 is configured as the downstream of first filter screen 163. Optionally, flushing device 1124 includes at least one backwash spray arm disposed inside first filter screen 163 and spraying water toward the peripheral wall of first filter screen 163. The backflushing spray arm can be used to quickly clean the first filter screen 163, thereby improving the cleaning efficiency and effect of the filter screen.

[0081] Optionally, the backwash spray arm is configured to extend along the axis of the first filter screen 163 and deviate from the central axis of the first filter screen 163, so that the nozzle of the backwash spray arm can be close to the peripheral wall of the first filter screen 163, thereby increasing the impact force and flushing effect of the water flow on the first filter screen 163. The water spraying range of the nozzle of at least one backwash spray arm covers the first filter screen 163 along the axis of the first filter screen 163. In other words, the flushing area of ​​the backwash spray arm can cover the entire first filter screen 163 along the axis, thereby increasing the flushing range of the first filter screen 163 and achieving effective flushing. In addition, the first filter screen 163 of the present invention can be configured to rotate. In this way, during the flushing process, the backwash spray arm can be used to flush and clean the entire first filter screen 163.

[0082] Optionally, the recoil spray arms may include multiple recoil spray arms, which may be distributed along the circumference of the first filter screen 163. In this way, the nozzles of multiple recoil spray arms are used to cover the filtering area of ​​the first filter screen 163, which can reduce the nozzle arrangement density of the recoil spray arms, so as to improve the structural strength of the recoil spray arms and increase the impact force of the nozzles.

[0083] In some embodiments, the flushing device 1124 is connected to the outlet of the circulation pump 12, and the circulation pump 12 can be used to deliver water for flushing to the flushing device 1124. The pumping action of the circulation pump 12 can be used to backwash the first filter 163, which can simplify the structure of the residue collection filter device 10. Moreover, during the process of washing tableware in the dishwasher, the first filter 163 can be backwashed at the same time, thereby improving the filtering efficiency and effect of the residue collection filter device 10.

[0084] Optionally, the slag collection and filtering device 10 is provided with a water diversion valve 1111 for connecting to the spray arm. The outlet of the circulating pump 12 is connected to the water diversion valve 1111. The circulating pump 12 is connected to a flushing branch, one end of which is connected to the outlet and the other end is connected to the flushing device 1124. This can further simplify the structure of the slag collection and filtering device 10 and improve the cleaning efficiency and effect of the first filter screen 163.

[0085] Example 5

[0086] like Figures 1 to 10 The flow channel plate 112 is also provided with a transmission cavity 1123 , in which a transmission assembly 15 is provided. The slag collecting and filtering device 10 also includes a driving member 14 , and the transmission assembly 15 is connected to the driving member 14 , the first filter screen 163 and the second filter screen 164 .

[0087] The driving member 14 is connected to the first filter screen 163 and the second filter screen 164 and is used to rotate the first filter screen 163 and the second filter screen 164. In other words, the driving member 14 can be used to drive the first filter screen 163 and the second filter screen 164 to rotate, thereby further improving the surface cleanliness of the first filter screen 163 and the second filter screen 164 and enhancing the filtering effect of the first filter screen 163 and the second filter screen 164.

[0088] Optionally, the driving member 14 is arranged side by side outside the water cup 11. The arrangement of components of the slag collecting and filtering device 10 can be optimized, the size of the slag collecting and filtering device 10 in the vertical direction can be reduced, and the space utilization of the slag collecting and filtering device 10 can be improved.

[0089] Among them, such as Figures 5 to 7 The transmission assembly 15 may include a first gear 151, a second gear 152, and a third gear 153. The first gear 151, the second gear 152, and the third gear 153 are in transmission connection with each other. The first gear 151 is in transmission connection with the driving member 14, the second gear 152 is in transmission connection with the first filter 163, and the third gear 153 is in transmission connection with the second filter 164. The first gear 151, the second gear 152, and the third gear 153 may be disposed in the transmission cavity 1123.

[0090] The transmission assembly 15 may further include a first shaft 154. The upper end of the first filter screen 163 is provided with a first mounting hole. The upper end of the first shaft 154 is inserted into the first mounting hole. A key fit may be provided between the first shaft 154 and the first mounting hole to facilitate rotation of the first filter screen 163 by the first shaft 154. The lower end of the first shaft 154 is connected to the second gear 152. The lower end of the first shaft 154 is inserted into the bottom wall of the filter chamber 102 and is provided with a bearing and an oil seal.

[0091] The transmission assembly 15 may further include a second shaft 155. The upper end of the second filter screen 164 is provided with a second mounting hole. The upper end of the second shaft 155 is inserted into the second mounting hole. A key fit may be provided between the second shaft 155 and the second mounting hole to facilitate rotation of the second filter screen 164 by the second shaft 155. The lower end of the second shaft 155 is connected to the second gear 152. The lower end of the second shaft 155 is inserted into the bottom wall of the filter chamber 102 and is provided with a bearing and an oil seal.

[0092] like Figure 3 and Figure 8 In some embodiments, the residue collection and filtering device 10 further includes a first flow spoiler 1631, which is disposed in the filter chamber 102 and is used to agitate the wash water in the filter chamber 102. The first flow spoiler 1631 can be used to promote turbulent flow in the filter chamber 102, further preventing the first filter screen 163 from being blocked, and facilitating the flow of residue into the residue collection chamber 103, thereby facilitating the collection of the residue.

[0093] The first spoiler 1631 of the present invention may include but is not limited to the following embodiments and their combinations.

[0094] In the first embodiment, the first spoiler 1631 is rotatably mounted on the filter chamber 102. The first spoiler 1631 can rotate to disrupt the fluid within the filter chamber 102. In the second embodiment, the first spoiler 1631 includes multiple blades spaced circumferentially, which can enhance the disruptive effect on the fluid within the filter chamber 102. The first spoiler 1631 can be configured to rotate about a circular axis. Thus, during rotation, the multiple blades can disrupt the fluid within the filter chamber 102. Optionally, the filter chamber 102 is provided with a rotatable first filter screen 163. Blades are provided at the ends of the first filter screen 163 to agitate the mixture of residue and water within the filter chamber 102, facilitating the removal of residue. Blades are also provided at one end of the first filter screen 163. During rotation, the first spoiler 163 pushes water against the side filter screen surface, separating residue from the filter screen. In the third embodiment, the first spoiler 1631 and the first filter screen 163 are relatively stationary. When the first filter screen 163 rotates, it drives the first spoiler 1631 to rotate, thereby simplifying the drive structure of the first spoiler 1631. Specifically, the first spoiler 1631 can be connected to the lower end of the first filter screen 163 and include a plurality of first blades spaced circumferentially around the first filter screen 163. In a fourth embodiment, the first spoiler 1631 can also be positioned relative to the filter chamber 102. This allows eddies to be generated when water flows through the first spoiler 1631, and the eddies are used to disrupt the water flow. In a fifth embodiment, at least a portion of the first spoiler 1631 is located at the lower portion of the filter chamber 102. This can enhance the flow disturbance effect on the fluid within the filter chamber 102. In a sixth embodiment, the first spoiler 1631 is connected to the lower end of the first filter screen 163 and is distributed along the direction surrounding the first filter screen 163.

[0095] In some embodiments, the residue collection and filtering device 10 further includes a second flow disruptor 1641, which is disposed in the residue collection chamber 103 and is configured to agitate the water and residue within the residue collection chamber 103. The second flow disruptor 1641 can be utilized to promote turbulent flow within the residue collection chamber 103, thereby facilitating the collection of residue. When the residue collection chamber 103 is being drained, the second flow disruptor 1641 can also be utilized to disrupt the flow of fluid within the residue collection chamber 103, thereby facilitating the emptying of residue within the residue collection chamber 103, facilitating cleaning of the dishwasher, preventing bacterial growth, and improving the cleaning performance and safety of the dishwasher.

[0096] The second spoiler 1641 of the present invention may include but is not limited to the following embodiments and their combinations.

[0097] In the first embodiment, the second spoiler 1641 is rotatably mounted within the slag collecting chamber 103. Rotation of the second spoiler 1641 disrupts the flow of the fluid within the slag collecting chamber 103. In the second embodiment, the second spoiler 1641 includes multiple blades spaced circumferentially, which can enhance the flow disturbance effect on the fluid within the slag collecting chamber 103. Furthermore, the second spoiler 1641 can be configured to rotate about a circular axis. Thus, during rotation, the multiple blades can disrupt the flow of the fluid within the slag collecting chamber 103. Optionally, the slag collecting chamber 103 is provided with a rotatable second filter screen 164. Blades are mounted at the ends of the second filter screen 164 to agitate the slag and water within the slag collecting chamber 103, facilitating the discharge of the residue. Blades are also mounted on one end of the second filter screen 164. During rotation, the second spoiler 1641 propels water across the side filter screen surface, separating the residue from the filter screen. In the third embodiment, the second spoiler 1641 and the second filter screen 164 are relatively stationary. When the second filter screen 164 rotates, it can drive the second spoiler 1641 to rotate, thereby simplifying the drive structure of the second spoiler 1641. Optionally, the second spoiler 1641 is connected to the lower end of the second filter screen 164 and includes a plurality of second blades spaced apart along the circumference of the second filter screen 164. In a fourth embodiment, the second spoiler 1641 can also be set to be relatively stationary relative to the slag collecting chamber 103. In this way, when the water flows through the second spoiler 1641, a vortex is generated, and the vortex is used to disturb the water flow. In a fifth embodiment, at least a portion of the second spoiler 1641 is located in the lower part of the slag collecting chamber 103. This can enhance the flow disturbance effect on the fluid in the slag collecting chamber 103. In a sixth embodiment, the second spoiler 1641 is connected to the lower end of the second filter screen 164 and is distributed in a direction surrounding the second filter screen 164.

[0098] In some embodiments, the first filter 163 is cylindrical, with the peripheral wall of the first filter 163 used to filter the wash water. This can increase the filtration area of ​​the first filter 163, thereby achieving a greater flow rate of filtration and ensuring the dishwasher's washing efficiency. In conjunction with the aforementioned arrangement of the first filter 163 rotatably mounted within the filter chamber 102 about its axis, the interior space of the first filter 163 is opposite the first outlet 1022.

[0099] like Figure 3 and Figure 9 In some embodiments, the second filter 164 is cylindrical in shape. The peripheral wall of the second filter 164 is used for filtering. The inner space of the second filter 164 communicates with the second outlet 1032, and the outer space of the second filter 164 communicates with the second inlet 1031 and the residue discharge port 1033. This increases the filtering area of ​​the second filter 164, thereby achieving a higher flow rate of filtration and ensuring the washing efficiency of the dishwasher. In conjunction with the aforementioned configuration of the second filter 164 being rotatably mounted about its axis within the residue collection chamber 103, the inner space of the second filter 164 is opposite the second outlet 1032.

[0100] In some embodiments, the filter mesh pore size of the first filter screen 163 is set to be no less than 0.1 mm and no greater than 1 mm. When the first filter screen 163 is rotatable and the rotation speed is relatively high (for example, greater than 1000 rpm), the filter mesh pore size of the first filter screen 163 can be appropriately enlarged. Optionally, the filter mesh pore size of the first filter screen 163 is set to be no less than 0.6 mm and no greater than 1 mm. For example, the filter mesh pore size of the first filter screen 163 can be set to 0.1 mm, 0.2 mm, 0.35 mm, 0.5 mm, 0.6 mm, 0.75 mm, or 1 mm, etc. Of course, when the rotation speed of the first filter screen 163 is relatively low (for example, no greater than 1000 rpm), the filter mesh pore size of the first filter screen 163 can be appropriately reduced.

[0101] In some embodiments, the pore size of the second filter screen 164 is set to be no less than 0.1 mm and no greater than 1 mm. When the second filter screen 164 is rotatable and the rotation speed is relatively high (e.g., greater than 1000 rpm), the pore size of the second filter screen 164 can be appropriately enlarged. Alternatively, the pore size of the second filter screen 164 is set to be no less than 0.6 mm and no greater than 1 mm. For example, the pore size of the second filter screen 164 can be set to 0.1 mm, 0.2 mm, 0.35 mm, 0.5 mm, 0.6 mm, 0.75 mm, or 1 mm, etc. Of course, when the rotation speed of the second filter screen 164 is relatively low (e.g., no greater than 1000 rpm), the pore size of the second filter screen 164 can be appropriately reduced.

[0102] In some embodiments, the inner bottom surface of the slag collecting chamber 103 is configured as a gradually downwardly sloping surface from the filter chamber 102 to the slag discharge port 1033. This facilitates the flow of residue or water into the slag collecting chamber 103 toward the slag discharge port 1033, facilitating smooth slag discharge from the slag discharge port 1033 and preventing residue from accumulating in the slag collecting chamber 103 and causing bacterial growth. Optionally, the lower end of the second filter screen 164 is higher than the inner bottom surface of the slag collecting chamber 103. This prevents residue remaining in the slag collecting chamber 103 from adhering to the surface of the second filter screen 164, thereby improving the filtration performance of the second filter screen 164. Optionally, a boss is provided on the inner bottom surface of the slag collecting chamber 103, with the second outlet 1032 located on the top surface of the boss, and the second filter screen 164 is located on the boss. This improves the filtration performance of the second filter screen 164 and allows the boss to provide support for the second filter screen 164, maintaining its stability.

[0103] The utility model also provides a dishwasher, comprising the aforementioned residue collection and filtering device 10.

[0104] Combine Figures 1 to 10The slag collection and filtration device 10 of the present invention can include a water collection chamber 101, a filtration chamber 102, a slag collection chamber 103, a circulation pump 12, a drainage pump 13, and a water diversion valve 1111. It has a multi-stage filtration function, primarily utilizing a flat filter screen 161, a filter cup 162, a first filter screen 163, a second filter screen 164, a circulation pump 12, a driver 14, and a transmission assembly 15 for multi-stage filtration.

[0105] Specifically, the primary filtration system includes a flat filter 161 and a filter cup 162. During the washing process, water rinses the surface of the dishes, carrying debris to the bottom of the washing chamber. The water then flows through the flat filter 161 and collects in the water collection chamber 101. Debris smaller than the pore size of the flat filter 161 (the pore size of the flat filter 161 is 0.5-2 mm) enters the filter chamber 102. Debris larger than the pore size of the flat filter 161 enters the filter cup 162.

[0106] Filter cup 162 has two aperture sizes. The side aperture of filter cup 162 is small and can be set to 0.5 to 3 mm. The bottom aperture of filter cup 162 is large and can be set to 5 to 10 mm. Residue larger than the bottom aperture of filter cup 162 requires manual cleaning. Residue smaller than the bottom aperture of filter cup 162 and larger than the side aperture is discharged through drainage pump 13 during drainage. Residue smaller than the side aperture of filter cup 162 enters filter chamber 102. Primary filtration achieves filtration of residue larger than 3 mm.

[0107] The secondary filtration system consists of a first filter 163 and a second filter 164. The pore sizes of the first and second filters 163 and 164 can be the same or different. Water and debris entering the filter chamber 102 are filtered through the first filter 163. Tiny particles smaller than the first filter 163 pass through the filter and enter the circulation pump 12 along with the water. Residue larger than the first filter 163 (size ranges from 0.1 to 3 mm) enters the slag chamber 103. During drainage, the residue in the slag chamber 103 is discharged via the drainage pump 13.

[0108] The first filter screen 163 and the second filter screen 164 of the secondary filtration are driven to rotate by the driving member 14 and the transmission assembly 15. Under the action of centrifugal force, the residue is separated from the filter screen.

[0109] The first filter screen 163 and / or the second filter screen 164 of the present invention may be rotatable to utilize centrifugal separation.

[0110] Specifically, the water after the first-stage filtration enters the filter chamber 102, and the first filter screen 163 rotates at high speed under the drive of the driving member 14 (such as a motor). Through the high-speed rotation of the first filter screen 163, the pollutants attached to the surface of the first filter screen 163 are separated from the filter screen, so that the first filter screen 163 has better water permeability. A first blade is provided on the first filter screen 163. The rotating first blade pushes the water to flush the surface of the first filter screen 163, accelerates the separation of the residue and the filter screen, and makes the filter screen clean more thoroughly. In addition, the first inlet 1021 is provided on the peripheral surface of the filter chamber 102, the first outlet 1022 is provided on the bottom surface of the filter chamber 102, and the second inlet 1031 is provided on the peripheral surface of the filter chamber 102. When the circulation pump 12 is working, water is sucked from the filter chamber 102 into the pump chamber of the circulation pump 12. A low-pressure zone is formed at the first outlet 1022, the outside of the filter screen of the filter chamber 102 is a relatively high-pressure zone, and the first inlet 1021 is a relatively high-pressure zone; a low-pressure zone is formed at the second outlet 1032, and the second inlet 1031 is a relatively high-pressure zone. Therefore, some water will pass through the slag collecting chamber 103 and enter the second outlet 1032. Pollutants outside the first filter screen 163 are pushed along by the water flow toward the second inlet 1031 and enter the slag collecting chamber 103 through the second inlet 1031. Because the water flow in the slag collecting chamber 103 is relatively slow and a second filter screen 164 is provided at the second outlet 1032, pollutants are collected in the slag collecting chamber 103, realizing the residue collection function and separating pollutants from the circulating water. Therefore, the water used to wash the dishes is always clean water, avoiding secondary contamination of the dishes. In addition, the utility model is also provided with a cleaning module to clean the first filter screen 163, and the cleaning of the first filter screen 163 is achieved through the circulating water microfiltration function and the centrifugal cleaning filter screen function.

[0111] In addition, during the cleaning process, the water that has passed the first-stage filtration enters the slag collecting chamber 103 from the second inlet 1031 through the filter chamber 102. The residue is collected in the slag collecting chamber 103 and separated from the main circulating water, thereby achieving slag-water separation. In order to solve the problem of residue clogging the second filter screen 164, a second blade is provided at the bottom of the second filter screen 164. The second filter screen 164 is driven to rotate by a motor. The second blade drives the water flow to flush the surface of the filter screen, separating the residue from the surface of the filter screen. When draining, the second filter screen 164 rotates, and the second spoiler 1641 stirs the water in the slag collecting chamber 103, causing the residue to mix with the water and move. The residue is discharged through the slag discharge port 1033 of the slag collecting chamber 103. The slag collecting chamber 103 can realize the functions of residue collection and slag-water separation.

[0112] The slag collection and filtration device 10 of the utility model can separate the residue from the circulating water, achieving clean water washing and avoiding secondary pollution. Centrifugal separation can automatically clean the filter screen, eliminating the need for manual maintenance. It can ensure stable water output from the water pump and improve the working efficiency of the water pump. It can also make it easier to discharge the accumulated residue. All filters can be easily removed for easy maintenance.
