Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a slag collecting component 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

DETAILED DESCRIPTION

[0034] 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.

[0035] like Figures 1 to 6 According to an embodiment of the present invention, the slag collection assembly 10 is used in a dishwasher. The slag collection assembly 10 has a water collection chamber 101 and a slag collection chamber 102. The slag collection chamber 102 is connected to the water collection chamber 101. The water collection chamber 101 is used to collect wash water. The slag collection chamber 102 is provided with a water outlet 103 and a slag discharge port 104. In addition, the slag collection assembly 10 includes a slag collection filter 121. The slag collection filter 121 is provided in the slag collection chamber 102 and is used to separate the residue and water in the wash water. The water separated from the wash water is discharged through the water outlet 103, and the separated residue remains in the slag collection chamber 102 and can be discharged through the slag discharge port 104.

[0036] Specifically, during the washing process of the dishwasher, the washing water flows into the water collection chamber 101. The washing water then flows from the water collection chamber 101 into the residue collection chamber 102. Under the filtering action of the residue collection filter 121, the water and residue are separated. The filtered water is then sent out from the water outlet 103. Driven by the circulation pump 161, the water sent out from the water outlet 103 is sent to the spray arm, which is used to wash the dishes. The remaining residue after filtration remains in the residue collection chamber 102. The water sprayed from the spray arm washes the dishes and then flows into the water collection chamber 101. During the drainage process, the residue remaining in the residue collection chamber 102 is discharged, thereby discharging the residue remaining in the residue collection assembly 10.

[0037] According to the slag collection assembly 10 of the embodiment of the present invention, the slag collection chamber 102 can collect residues, separating the residues from the circulating cleaning water, thereby keeping the circulating water clean. This allows for filtration of the wash water, and the slag collection chamber 102 can be used to collect residues. The wash water will be filtered through the slag collection filter 121 before entering the circulation. All wash water within the water collection chamber 101 will be filtered through the slag collection filter 121, achieving complete filtration of the wash water, improving the filtration efficiency of the wash water, enhancing the washing effect and stability of the dishwasher, and preventing or reducing the possibility of blockage in the dishwasher's pipes.

[0038] In some embodiments, the slag filter 121 is rotatably disposed within the slag chamber 102. The rotation of the slag filter 121 can be utilized to clean the filter surface, thereby maintaining the filtering performance of the slag filter 121. The centrifugal force generated during the rotation of the slag filter 121 separates debris adhering to the surface from the slag filter 121; the relative motion between the slag filter 121 and the water also separates debris adhering to the surface from the slag filter 121.

[0039] The slag filter 121 can be configured to rotate freely. In other words, the slag filter 121 can be configured to rotate under the driving force of the water flow, which can simplify the structure of the slag collection assembly 10 and facilitate the surface cleaning of the slag filter 121 during the filtering process.

[0040] In addition, if Figure 5 The slag collection assembly 10 may further include a driving member 13, which is in transmission connection with the slag collection filter 121 and is used to drive the slag collection filter 121 to rotate. In other words, the driving member 13 can be used to drive the slag collection filter 121 to rotate, thereby achieving passive rotation of the slag collection filter 121, thereby further improving the surface cleanliness of the slag collection filter 121 and improving the filtering effect of the slag collection filter 121.

[0041] The drive member 13 is arranged side by side outside the slag collection chamber 102. The slag collection assembly 10 also includes a transmission assembly, which is respectively connected to the drive member 13 and the slag collection filter 121, and is used to transmit the rotational motion of the drive shaft of the drive member 13 to the slag collection filter 121. This can optimize the component layout of the slag collection assembly 10, reduce the size of the slag collection assembly 10 in the vertical direction, and improve the space utilization of the slag collection assembly 10.

[0042] Among them, such as Figure 5 The transmission assembly may include a first gear 141 and a second gear 142, the first gear 141 is in transmission connection with the driving member 13, the second gear 142 is in transmission connection with the first gear 141, and the second gear 142 is in transmission connection with the slag collecting filter 121, wherein the transmission assembly can be arranged on the bottom wall of the slag collecting chamber 102, in addition, the water outlet 103 can also be arranged on the bottom wall of the slag collecting chamber 102, and a flow channel can be integrated in the bottom wall of the slag collecting chamber 102 for connecting to the circulation pump 161.

[0043] like Figure 5 and Figure 6In some embodiments, the residue filter 121 is cylindrical in shape. The peripheral wall of the residue filter 121 is used to filter wash water. The water outlet 103 is located inside the residue filter 121. The outer space of the residue filter 121 connects the water collection chamber 101 and the residue discharge port 104. This increases the filtration area of ​​the residue filter 121, thereby achieving a higher flow rate and ensuring the washing efficiency of the dishwasher. In conjunction with the aforementioned configuration in which the residue filter 121 is rotatably mounted within the residue collection chamber 102 about its axis, the interior space of the residue filter 121 is opposite the water outlet 103.

[0044] In some embodiments, such as Figure 5 and Figure 6 The slag collecting assembly 10 further includes a flow disruptor 122, which is disposed in the slag collecting chamber 102 and is used to stir the water and residue in the slag collecting chamber 102. The flow disruptor 122 can be used to promote turbulent flow in the slag collecting chamber 102, thereby facilitating the collection of residue. When the slag collecting chamber 102 is being drained, the flow disruptor 122 can also be used to disrupt the flow of fluid in the slag collecting chamber 102, thereby facilitating the emptying of residue in the slag collecting chamber 102, facilitating the cleaning of the dishwasher, preventing bacterial growth, and improving the cleaning effect and safety of the dishwasher.

[0045] The flow spoiler 122 is rotatably provided in the slag collecting chamber 102 , and the flow spoiler 122 can achieve flow disturbance of the fluid in the slag collecting chamber 102 by rotating.

[0046] Optionally, the spoiler 122 includes multiple blades spaced apart along the circumferential direction, which can enhance the disturbing effect on the fluid in the slag collecting chamber 102. Furthermore, the spoiler 122 can be configured to rotate about a circular axis. In this way, during the rotation of the spoiler 122, the multiple blades can be used to disturb the fluid in the slag collecting chamber 102. Optionally, the slag collecting chamber 102 is provided with a rotatable slag collecting filter 121. The ends of the slag collecting filter 121 are provided with blades that can stir the slag in the slag collecting chamber 102 and mix it with water, facilitating the discharge of the residue. The upper end of the slag collecting filter 121 is provided with blades that, when rotated, can push water to flush the side filter surface, separating the residue from the filter.

[0047] Optionally, the spoiler 122 is relatively stationary relative to the slag filter 121. Rotation of the slag filter 121 drives the spoiler 122, thereby simplifying the drive structure of the spoiler 122. Alternatively, the spoiler 122 can be relatively stationary relative to the slag chamber 102. This creates eddies when the water flows through the spoiler 122, which are then used to disrupt the water flow.

[0048] In addition, at least a portion of the flow disruptor 122 is located at the lower portion of the slag collecting chamber 102 , thereby improving the flow disrupting effect on the fluid in the slag collecting chamber 102 .

[0049] In some embodiments, the water collection chamber 101 and the residue collection chamber 102 are arranged side by side, and a communication port 105 is provided on the peripheral wall of the water collection chamber 101 to communicate with the residue collection chamber 102. This facilitates the flow of wash water in the water collection chamber 101 into the residue collection chamber 102, not only facilitating the collection of wash water in the water collection chamber 101 but also facilitating the filtration of the wash water and the retention of residue in the wash chamber.

[0050] Optionally, the communication port 105 is higher than the inner bottom surface of the water collection chamber 101, or the communication port 105 is higher than the inner bottom surface of the slag collection chamber 102, or the communication port 105 is higher than the inner bottom surface of the water collection chamber 101 and the inner bottom surface of the slag collection chamber 102, which can facilitate slag collection and prevent slag backflow. When the slag collection component 10 is filtering, the other positions of the slag collection chamber 102 except the communication port 105 and the water outlet 103 are closed. It can achieve the retention of residue in the slag collection chamber 102, improve the filtration efficiency and effect of the slag collection component 10,

[0051] In some embodiments, the pore size of the slag filter 121 is set to be no less than 0.1 mm and no greater than 1 mm. When the slag filter 121 is rotatable and the rotation speed is relatively high (e.g., greater than 1000 rpm), the pore size of the slag filter 121 can be appropriately enlarged. For example, the pore size of the slag filter 121 can be set to be no less than 0.6 mm and no greater than 1 mm. For example, the pore size of the slag filter 121 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 slag filter 121 is relatively low (e.g., no greater than 1000 rpm), the pore size of the slag filter 121 can be appropriately reduced.

[0052] In some embodiments, the inner bottom surface of the slag collecting chamber 102 is configured as a slope that gradually slopes downward from the water collecting chamber 101 to the slag discharge port 104. This allows residue or water that enters the slag collecting chamber 102 to flow toward the slag discharge port 104, facilitating smooth slag discharge from the slag discharge port 104 and preventing residue from accumulating in the slag collecting chamber 102 and causing bacterial growth. Optionally, the lower end of the slag collecting filter 121 is higher than the inner bottom surface of the slag collecting chamber 102, thereby preventing residue remaining in the slag collecting chamber 102 from adhering to the surface of the slag collecting filter 121 and improving the filtering performance of the slag collecting filter 121. Optionally, a boss 112 is provided on the inner bottom surface of the slag collecting chamber 102, the water outlet 103 is provided on the top surface of the boss 112, and the slag collecting filter 121 is provided on the boss 112. The filtering performance of the slag collecting filter screen 121 can be improved, and the boss 112 can be used to provide support for the slag collecting filter screen 121 to maintain the stability of the slag collecting filter screen 121.

[0053] In some embodiments, such as Figure 1 and Figure 5The slag discharge port 104 is provided with a one-way valve 123. The one-way valve 123 is configured to open the slag discharge port 104 in one direction along the slag discharge direction of the slag collecting chamber 102. Furthermore, a drainage port is provided at the bottom of the water collecting chamber 101. The slag discharge port 104 is provided at the bottom of the slag collecting chamber 102, and is connected to the water collecting chamber when the slag discharge port 104 is opened. During the filtration process, the drainage pump 162 is turned off, and the air pressure in the drainage channel is relatively high; the slag collecting chamber 102 is provided with a water outlet 103, and the fluid can be discharged from the slag collecting chamber 102 through the water outlet 103. The air pressure in the slag collecting chamber 102 is relatively low, and the one-way valve 123 is in a closed state. During the slag discharge process, the drainage pump 162 is running, and the air pressure in the drainage channel is relatively low, so that the slag collecting chamber 102 can be used to filter the washing water; the air pressure in the slag collecting chamber 102 is relatively high, and the one-way valve 123 is in an open state, so that the residue in the slag collecting chamber 102 can be discharged.

[0054] The slag collecting chamber 102 and the water collecting chamber 101 can be connected through a one-way valve 123. During cleaning, the one-way valve 123 is closed and the slag collecting chamber 102 realizes the slag collecting function; during drainage, the one-way valve 123 is opened, and the residue enters the water collecting chamber 101 from the slag collecting chamber 102 and is discharged through the drainage pump 162.

[0055] In some embodiments, such as Figure 6 The slag collection assembly 10 includes a water cup 11, a water collection chamber 101, and a slag collection chamber 102 disposed in the water cup 11. The water collection chamber 101 and the slag collection chamber 102 extend in the vertical direction. The upper end of the water collection chamber 101 passes through the top surface of the water cup 11. The upper end of the water collection chamber 101 opens to form a water inlet. The upper end of the slag collection chamber 102 passes through the top surface of the water cup 11. A slag collection chamber cover 124 is disposed at the upper end of the slag collection chamber 102 for sealing the slag collection chamber 102. This facilitates assembly and maintenance of the slag collection assembly 10 and improves assembly efficiency.

[0056] The slag chamber cover 124 is equipped with a positioning structure, and the slag filter 121 is positioned on the slag chamber cover 124, allowing for quick assembly of the slag chamber cover 124. Optionally, the slag chamber cover 124 is detachably connected to the water cup. This facilitates quick assembly and disassembly of the slag chamber cover 124, improves the stability of the slag collection assembly 10, and allows for easy inspection of the status of the slag chamber 102, facilitating cleaning of the slag collection assembly 10.

[0057] The slag collecting chamber cover 124 covers the water cup 11 and closes the slag collecting chamber 102. The circumferential surface of the slag collecting chamber cover 124 is provided with a groove. The slag collecting sealing ring is arranged along the circumference of the slag collecting chamber cover 124 and cooperates with the groove. The slag collecting sealing ring closes the gap between the slag collecting chamber cover 124 and the inner circumferential surface of the slag collecting chamber 102. In addition, the slag collecting chamber cover 124 is also provided with a bearing. The upper end of the slag collecting filter 121 is connected to the bearing, and the bearing is used to realize the rotational connection between the slag collecting filter 121 and the slag collecting chamber cover 124. The transmission assembly also includes a first shaft. The upper end of the slag filter 121 is provided with a mounting hole. The first shaft passes through the slag filter 121, and the upper end cooperates with the mounting hole. The cooperation between the first shaft and the mounting hole can be set as a spline cooperation, etc., so that the slag filter 121 can be driven to rotate by the first shaft. The lower end of the first shaft is connected to the second gear 142, and the driving shaft of the driving member 13 is connected to the first gear 141. The first gear 141 and the second gear 142 are connected in transmission, so that the driving member 13 is used to drive the first shaft to rotate, and then drive the slag filter 121 to rotate.

[0058] A flow path is defined within flow channel plate 111, one end of which is connected to water outlet 103 and the other end to circulation pump 161. An opening for circulation pump 161 is defined around the perimeter of water outlet 103, and an opening for the first shaft is defined on the bottom wall. An oil seal and bearing are located between the first shaft and flow channel plate 111.

[0059] In some embodiments, the slag collection assembly 10 further includes: a flat filter 151 having an opening and arranged to slope downward from the periphery to the opening, with the upper end of the water collection chamber 101 open and facing the opening; and a filter cup 152, which is inserted through the opening and the water collection chamber 101. The flat filter 151 can be used to filter the wash water once, further improving the filtration effect of the wash water. In addition, the filter cup 152 can retain larger residues, and the slag collection assembly 10 can be cleaned by removing the filter.

[0060] The dishwasher according to the embodiment of the present invention includes the aforementioned slag collecting assembly 10 .

[0061] The filter screens (filter cup 152, centrifugal filter screen and / or slag collection filter screen 121) in the present invention can be designed as an easily assembled and disassembled structure and can be taken out from the inside of the cleaning chamber, making subsequent maintenance more convenient.

[0062] The slag collection assembly 10 of the present invention may also include a centrifugal chamber. Specifically, the slag collection assembly 10 of the present invention comprises a water collection chamber 101, a centrifugal chamber, a slag collection chamber 102, a circulation pump 161, a drainage pump 162, and a water diversion valve. Furthermore, the assembly 10 may include a flat filter screen, a filter cup 152, a centrifugal filter screen, a slag collection filter screen 121, a circulation pump 161, and a drive element 13. The slag collection assembly 10 may include multiple stages of filtration.

[0063] The primary filtration consists of a flat filter and a filter cup 152. During the cleaning process, water rinses the surface of the dishes, carrying debris to the bottom of the cleaning chamber. The water then flows through the flat filter and collects in the water collection chamber 101. Debris smaller than the flat filter's pore size (0.5-2mm) enters the water collection chamber 101. Debris larger than the flat filter's pore size enters the filter cup 152.

[0064] Filter cup 152 has two aperture sizes. The side aperture of filter cup 152 is smaller, and can be set to 0.5 to 3 mm. The bottom aperture of filter cup 152 is larger, and can be set to 5 to 10 mm. Debris larger than the bottom aperture of filter cup 152 requires manual cleaning. Debris smaller than the bottom aperture of filter cup 152 and larger than the side aperture is discharged by drain pump 162 during drainage. Debris smaller than the side aperture of filter cup 152 enters the debris collection chamber 102. This first-stage filtration achieves filtration of debris larger than 3 mm.

[0065] The secondary filtration is composed of modules such as a centrifugal filter, a slag filter 121 and a drive 13. The centrifugal filter and the slag filter 121 have the same pore size, which can be set to 0.4-0.1mm, preferably 0.25-0.35mm. The water and residue entering the centrifugal chamber are filtered through the centrifugal filter, and tiny particles smaller than the filter can pass through the filter and enter the circulation pump 161 together with the water. Residue larger than the filter (size of 0.1-3mm) enters the slag chamber 102. During drainage, the residue in the slag chamber 102 is discharged through the drainage pump 162.

[0066] The centrifugal filter screen and the residue collection filter screen 121 of the secondary filtration are driven to rotate by the driving member 13. Under the action of centrifugal force, the residue is separated from the filter screen.

[0067] The water after multi-stage filtration is pressurized by the circulation pump 161, and most of the water enters the spray channel through the water diversion valve module. A small amount of water enters the backwash channel through the backwash channel port set on the pump outlet channel, and is then diverted to multiple backwash spray arms and sprayed onto the centrifugal filter through the backwash nozzle. The centrifugal filter is cleaned from the inside to the outside in reverse. The pollutants attached to the surface of the centrifugal filter are separated from the centrifugal filter, making the filter more permeable. The filter rotates under the drive of the motor, so that the entire filter can be cleaned.

[0068] The slag collecting chamber 102 is connected to the water collecting chamber, and is provided with a water outlet 103 connected to the circulating pump 161. When the circulating water pump is working, it draws water into the pump chamber. A low-pressure area is formed at the inlet flow channel of the circulating pump 161, the water collecting chamber 101 (or the aforementioned centrifugal chamber) is a relatively high-pressure area, and the connecting port is located in a relatively high-pressure area. Therefore, some water will pass through the slag collecting chamber 102 and enter the inlet flow channel of the circulating pump 161. The pollutants on the outside of the filter are pushed toward the connecting port with the water flow and enter the slag collecting chamber 102 through the connecting port. Since the water flow in the slag collecting chamber 102 is relatively slow, and a slag collecting filter 121 is provided in the slag collecting chamber 102, the pollutants are collected in the slag collecting chamber 102, realizing the residue collection function and separating the pollutants from the circulating water. Therefore, the water used to wash the tableware is always clean water, avoiding secondary contamination of the tableware.

[0069] The slag collecting chamber 102 and the slag collecting filter 121 in the present invention constitute a slag collecting module. The slag collecting module includes at least one of the slag collecting chamber 102, the slag collecting filter 121, the slag collecting cover, the first shaft, the first gear 141, the second gear 142, the bearing, the oil seal, the sealing ring, and the one-way valve 123.

[0070] During the cleaning process, the water that has passed the first-stage filtration enters the slag collecting chamber 102, and the residue is collected in the slag collecting chamber 102 and separated from the main circulating water to achieve slag-water separation. In order to solve the problem of residue clogging the slag collecting filter 121, blades are provided at the bottom of the slag collecting filter 121, and the slag collecting filter 121 is driven by the slag collecting motor to rotate. The blades drive the water flow to flush the filter surface, so that the residue is separated from the filter surface.
