Description

Technical Field

[0001] This application relates to the field of dishwasher technology, and in particular to an automatic feeder and dishwasher. Background Technology

[0002] Currently, dishwashers are widely favored by families due to their efficient cleaning capabilities. However, they require the addition of specialized detergent and rinse aid for optimal results. Detergent removes grease, softens water, and prevents tableware corrosion; it can be added manually or automatically. Rinse aid removes water stains, leaving tableware shiny and spotless, and speeds up drying. Both detergent and rinse aid are added through the dispenser. However, current dishwashers often have a single integrated dispenser and rack. This means that if the dispenser's pipes become clogged or malfunction, repair and replacement often require professional technicians; customers cannot repair or replace the internal parts themselves. Utility Model Content

[0003] Therefore, it is necessary to provide an automatic feeder and dishwasher to solve the problem that existing dishwashers are difficult to repair when their automatic feeders malfunction.

[0004] The automatic dispensing box provided in this application includes a flip cover, an assembly cover, an assembly body, a dispensing component, a filling tube, and a liquid storage section. The assembly body is fixedly installed on one side of the liquid storage section and has an assembly port. The dispensing component can be detachably installed into the assembly body through the assembly port. The assembly cover is detachably installed at the assembly port. The flip cover is located on the side of the assembly cover opposite to the dispensing component and is detachably connected to the assembly body. One end of the filling tube is connected to the liquid storage section, and the other end passes through the assembly body and the assembly cover in sequence. The flip cover can be opened or sealed at the opening of the filling tube. The dispensing component is connected to the liquid storage section and can draw the detergent in the liquid storage section into the receiving area between the flip cover and the assembly cover.

[0006] In one embodiment, the automatic feeding box further includes a first exhaust pipe, one end of which is connected to the first receiving cavity, and the other end extends out of the first tube body and connects to the receiving area. When detergent is added through the first tube body, the air in the first receiving cavity can be discharged to the receiving area through the first exhaust pipe.

[0007] In one embodiment, the dispensing assembly includes a first peristaltic pump and a first connecting tube assembly. The first peristaltic pump is connected to a first receiving cavity and a receiving area via the first connecting tube assembly. When the first peristaltic pump rotates forward, it draws detergent from the first receiving cavity into the receiving area. When the first peristaltic pump rotates in reverse, it transfers detergent from the first connecting tube assembly into the first receiving cavity. The dispensing assembly also includes a second peristaltic pump and a second connecting tube assembly. The second peristaltic pump is connected to a second receiving cavity and a receiving area via the second connecting tube assembly. When the second peristaltic pump rotates forward, it draws polish from the second receiving cavity into the receiving area. When the second peristaltic pump rotates in reverse, it transfers polish from the second connecting tube assembly into the second receiving cavity.

[0008] In one embodiment, the first peristaltic pump can control the flow rate P of the detergent inside itself to satisfy 0.1g / s≤P≤1g / s; the second peristaltic pump can control the flow rate Q of the rinse aid inside itself to satisfy 0.1g / s≤Q≤1g / s.

[0009] In one embodiment, P equals 0.5 g / s; and / or, Q equals 0.5 g / s.

[0010] In one embodiment, the first connecting pipe assembly includes a first straight pipe section, a second straight pipe section, a third straight pipe section, and a fourth straight pipe section. A first peristaltic pump draws detergent from the reservoir through the second straight pipe section and the first straight pipe section, and transfers the detergent to the receiving area through the third straight pipe section and the fourth straight pipe section. The second connecting pipe assembly includes a fifth straight pipe section, a sixth straight pipe section, a seventh straight pipe section, and an eighth straight pipe section. A second peristaltic pump draws polishing agent from the reservoir through the sixth straight pipe section and the fifth straight pipe section, and transfers the polishing agent to the receiving area through the seventh straight pipe section and the eighth straight pipe section.

[0011] In one embodiment, the first connecting pipe assembly further includes a first sealing ring and a second sealing ring. A plurality of first sealing rings are spaced apart and sleeved on the second straight pipe section to seal the gap between the second straight pipe section and the liquid storage part. A plurality of second sealing rings are spaced apart and sleeved on the fourth straight pipe section to seal the gap between the fourth straight pipe section and the assembly body.

[0012] In one embodiment, the second connecting pipe assembly further includes a third sealing ring and a fourth sealing ring. A plurality of third sealing rings are spaced apart on the sixth straight pipe section to seal the gap between the sixth straight pipe section and the liquid storage part, and a plurality of fourth sealing rings are spaced apart on the eighth straight pipe section to seal the gap between the eighth straight pipe section and the assembly body.

[0013] In one embodiment, the dispensing assembly includes a first dispensing valve, a first solenoid valve, and a third connecting pipe assembly. The first solenoid valve controls the start and stop of the first dispensing valve and the flow rate of the detergent. The first dispensing valve is connected to a first receiving cavity and a receiving area via the third connecting pipe assembly. The first solenoid valve can control the first dispensing valve to draw detergent from the first receiving cavity into the receiving area. The dispensing assembly also includes a second dispensing valve, a second solenoid valve, and a fourth connecting pipe assembly. The second solenoid valve controls the start and stop of the second dispensing valve, the flow rate of the rinse aid, and the flow direction of the rinse aid. The second dispensing valve is connected to a second receiving cavity and a receiving area via the fourth connecting pipe assembly. The second solenoid valve can control the second dispensing valve to draw rinse aid from the second receiving cavity into the receiving area.

[0014] This application also provides a dishwasher that includes the automatic feeder box described in any of the above embodiments.

[0015] Compared to existing technologies, the automatic dispensing box and dishwasher provided in this application, specifically, allow users to directly remove the dispensing component for cleaning or replacement after sequentially disassembling the flip-top and assembly cover when maintenance is required. The structural design of the filling tube penetrating through the assembly body and assembly cover ensures unobstructed liquid delivery while providing sufficient space for disassembly. After the dispensing component is inserted into the assembly body through the assembly port, it is sealed by the assembly cover. Under normal operating conditions, the dispensing component delivers the detergent from the storage compartment to the receiving area via piping, and finally flows into the washing basin through the flip-top gap groove under gravity. This structure, through modular design, centralizes vulnerable components in the removable area, significantly reducing maintenance difficulty.

[0016] Compared to existing technologies, this solution uses a standardized interface connection, allowing users to directly disconnect faulty components. Furthermore, through the aforementioned technical solution, this application achieves rapid disassembly and maintenance of the core components of the automatic feeding box, enabling users to replace dispensing components or clean filling pipes without the need for specialized tools. The modular design significantly lowers the maintenance threshold; in the event of pipe blockage or pump failure, consumers can disassemble the corresponding module for maintenance themselves, avoiding downtime caused by returning the entire machine to the factory for repair. The layered sealing structure ensures reliable liquid delivery while effectively preventing liquid leakage even after each module is disassembled. Attached Figure Description

[0027] Please see Figures 1-8 This application provides an automatic feeding box and a dishwasher. The automatic feeding box includes a flip cover 100, an assembly cover 200, an assembly body 300, a dispensing component 400, a filling tube 500, and a liquid storage section 600. The assembly body 300 is fixedly installed on one side of the liquid storage section 600. The assembly body 300 has a small cross-sectional area but a large depth, so the assembly body 300 is generally cubic in shape. Correspondingly, the liquid storage section 600 has a large cross-sectional area but a shallow depth, so the liquid storage section 600 is generally flat and plate-shaped. The assembly body 300 is disposed on one side of the liquid storage section 600. When the automatic feeding box flips over, the assembly body 300 is located at the lower end of the liquid storage section 600 to facilitate access within the liquid storage section 600. The assembly body 300 is provided with an assembly port 320, through which the dispensing component 400 can be detachably installed into the assembly groove 310 of the assembly body 300. Specifically, the dispensing component 400 can be installed in the assembly body 300 via a snap-fit ​​or threaded connection to allow detergent and rinse aid to flow quickly into the dishwasher's sink. The assembly cover 200 is detachably installed at the assembly port 320 to seal the space where the dispensing component 400 is located. Specifically, the assembly cover 200 is threaded to the assembly body 300 by multiple screws 210 around its perimeter. Of course, in other embodiments, the assembly cover 200 can also be snapped into the assembly body 300. The flip cover 100 is located on the side of the assembly cover 200 away from the distribution component 400 and is detachably connected to the assembly body 300. Specifically, one end of the flip cover 100 is provided with two opposing rotating protrusions 110. The two rotating protrusions 110 are coaxially arranged to form the rotation axis of the flip cover 100. The assembly body 300 is provided with two corresponding rotating holes 330. The two rotating protrusions 110 are rotatably engaged in the rotating holes 330 so that the flip cover 100 can rotate relative to the assembly body 300.

[0028] One end of the filling tube 500 is connected to the liquid storage section 600, and the other end passes through the assembly body 300 and the assembly cover 200 in sequence, and connects the area between the assembly cover 200 and the flip cover 100. The flip cover 100 can be opened or sealed at the opening of the filling tube 500 by the compression sealing ring 140. It should be noted that the compression sealing ring 140 has a certain amount of compression. Specifically, the filling tube 500 includes a first tube body 510 and a second tube body 520. The liquid storage section 600 is provided with a first receiving cavity 610 and a second receiving cavity 630. The first receiving cavity 610 has a first filling hole 620. One end of the first tube body 510 is sealed and connected to the first filling hole 620, and the other end passes through the assembly body 300 and the assembly cap 200. The first tube body 510 is used for filling detergent. The second receiving cavity 630 has a second filling hole 640. One end of the second tube body 520 is sealed and connected to the second filling hole 640, and the other end passes through the assembly body 300 and the assembly cap 200. The second tube body 520 is used for filling rinse aid. Specifically, when detergent needs to be added to the liquid storage section 600, detergent can be injected into the first receiving cavity 610 through the first tube body 510. The first receiving cavity 610 is sealed and connected to the first tube body 510 through the independent first filling hole 620, ensuring that the detergent flows in only one direction during the filling process. Similarly, the brightener is injected into the second receiving cavity 630 through the second tube 520. The two receiving cavities are completely separated by a physical isolation structure to prevent liquid mixing. The through holes of the assembly body 300 and the assembly cover 200 are matched with the first tube 510 and the second tube 520, respectively, to form a stable fluid transmission path.

[0029] More specifically, the first tube 510 and the second tube 520 are integrally formed in the liquid storage section 600. They can be integrally injection molded or 3D printed. Of course, the first tube 510 and the second tube 520 can also be welded to the liquid storage section 600 respectively.

[0030] It is important to note that Figure 2 and Figure 4 The parts of the flip cover 100 that seal the first tube 510 and the second tube 520 are solid parts, not holes. They look like holes because the surface of the flip cover 100 is recessed, so that the words representing detergent and rinse aid can be machined in the recessed area.

[0031] More specifically, such as Figure 3As shown, the liquid storage section 600 is provided with a partition strip 650 to divide the liquid storage section 600 into a first receiving cavity 610 and a second receiving cavity 630 that are not connected. The partition strip 650 can be integrally formed with the shell of the liquid storage section 600 to improve the sealing performance. Furthermore, the volume of the second receiving cavity 630 is smaller than the volume of the first receiving cavity 610, so that the liquid storage section 600 can hold more detergent, which is mainly because the amount of detergent used is greater than the amount of rinse aid.

[0032] The dispensing component 400 connects to the liquid storage section 600 and is capable of drawing cleaning agents (including detergent and rinse aid) from the liquid storage section 600 into the receiving area 120 between the flip cover 100 and the mounting cover 200. This allows the cleaning agents in the receiving area 120 to flow into the dishwasher's washing tub through the gap groove 130 of the receiving area 120 when the automatic feeder is flipped. The gap groove 130 of the receiving area 120 is formed by a gap notch provided at the connection between the flip cover 100 and the mounting cover 200.

[0033] Specifically, when maintenance is required, the user can disassemble the flip cover 100 and the assembly cover 200 in sequence, and then directly remove the dispensing component 400 for cleaning or replacement. The structural design of the filling pipe 500 passing through the assembly body 300 and the assembly cover 200 ensures unobstructed liquid delivery and provides sufficient space for disassembly. After the dispensing component 400 is inserted into the assembly body 300 through the assembly port 320, it is sealed by the assembly cover 200. Under normal operating conditions, the dispensing component 400 delivers the cleaning agent in the storage section 600 to the receiving area 120 for temporary storage through the pipeline, and finally flows into the sink through the gap groove 130 of the flip cover 100 by gravity. This structure, through modular design, concentrates vulnerable parts in the removable area, significantly reducing maintenance difficulty.

[0034] Compared to existing technologies, this solution uses a standardized interface connection, allowing users to directly disconnect faulty components. Furthermore, through the above technical solution, this application achieves rapid disassembly and maintenance of the core components of the automatic feeding box; users can replace the dispensing component 400 or clean the filling pipe 500 without specialized tools. The modular design significantly lowers the maintenance threshold; when pipeline blockage or pump failure occurs, consumers can disassemble the corresponding module for maintenance themselves, avoiding interruptions caused by returning the entire machine to the factory for repair. The layered sealing structure ensures reliable liquid delivery while effectively preventing liquid leakage even after each module is disassembled.

[0035] In one embodiment, such as Figure 3As shown, a first float 611 is provided inside the first receiving cavity 610, and a magnet is provided inside the first float 611. When the detergent level in the first receiving cavity 610 is higher than the minimum level, the first float 611 rotates and abuts against the upper first stop post 612. When the detergent level in the first receiving cavity 610 is lower than the minimum level, the first float 611 rotates and abuts against the lower first sensing part 613. The interaction between the circuit board of the first float 611 and the first sensing part 613 is mainly achieved through the distance between the magnet inside the first float 611 and the Hall element on the circuit board of the first sensing part 613. When the detergent level is lower than the minimum level, the magnet inside the first float 611 approaches the Hall element of the first sensing part 613, and the circuit board of the first sensing part 613 issues an alarm signal.

[0036] Correspondingly, such as Figure 3 As shown, a second float 631 is provided inside the second receiving cavity 630. A magnet is installed inside the second float 631. When the level of the polishing agent in the second receiving cavity 630 is higher than the minimum level, the second float 631 rotates and abuts against the upper second stop 632. When the level of the polishing agent in the second receiving cavity 630 is lower than the minimum level, the second float 631 rotates and abuts against the lower second sensing unit 633. The interaction between the circuit board of the second float 631 and the second sensing unit 633 is mainly achieved through the distance between the magnet inside the second float 631 and the Hall element on the circuit board of the second sensing unit 633. When the level of the polishing agent is lower than the minimum level, the magnet inside the second float 631 approaches the Hall element of the second sensing unit 633, and the circuit board of the second sensing unit 633 emits an alarm signal.

[0037] In one embodiment, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the automatic feeding box also includes a first exhaust pipe 700. One end of the first exhaust pipe 700 is connected to the first receiving cavity 610, and the other end extends out of the first tube body 510 and connects to the receiving area 120. When detergent is added through the first tube body 510, the air in the first receiving cavity 610 can be discharged to the receiving area 120 through the first exhaust pipe 700.

[0038] It should be noted that, in order to enhance exhaust performance, such as Figure 3 As shown, the first receiving cavity 610 is provided with a Z-shaped or U-shaped extending rib 660. The extending rib 660 divides the first receiving cavity 610 into an exhaust channel 661. One end of the exhaust channel 661 is connected to the first exhaust pipe 700, and the other end is connected to a position in the first receiving cavity 610 away from the first pipe body 510. Furthermore, the distance between the end of the extending rib 660 (the end connected to the first receiving cavity 610) and the side wall of the first receiving cavity 610 is greater than or equal to 1 mm and less than or equal to 10 mm.

[0039] Specifically, when the user adds detergent to the first receiving cavity 610 through the first tube 510, the liquid enters the cavity and gradually fills the space. At this time, the air originally in the cavity is compressed and flows outward along the first exhaust pipe 700. Since the end of the first exhaust pipe 700 extends to the receiving area 120, the air is finally discharged to the outside of the sink through the gap groove 130 of the flip cover 100, avoiding air stagnation that could cause the liquid level sensor to misjudge or insufficient filling. In this process, the nested design of the first exhaust pipe 700 and the first tube 510 ensures both the sealing of the filling channel and independent control of the exhaust path.

[0040] However, this is not the only embodiment. In other embodiments, the automatic feeding box also includes a second exhaust pipe (not shown). One end of the second exhaust pipe is connected to the second receiving cavity 630, and the other end extends out of the second tube body 520 and connects to the receiving area 120. When brightener is added through the second tube body 520, the air in the second receiving cavity 630 can be discharged to the receiving area 120 through the second exhaust pipe.

[0041] Example 1

[0042] In this embodiment, as Figure 6 As shown, the dispensing assembly 400 includes a first peristaltic pump 410 and a first connecting pipe assembly 420. The first peristaltic pump 410 is connected to the first receiving cavity 610 and the receiving area 120 through the first connecting pipe assembly 420. That is, when the first peristaltic pump 410 rotates forward, it can draw detergent from the first receiving cavity 610 into the receiving area 120; when the first peristaltic pump 410 rotates in reverse, it can transfer detergent from the first connecting pipe assembly 420 into the first receiving cavity 610.

[0043] Specifically, when detergent needs to be added, the forward rotation of the first peristaltic pump 410 drives the rollers to squeeze the hose of the first connecting pipe assembly 420, causing the detergent to be drawn from the first receiving chamber 610 into the pump body through the first straight pipe section 421 and the second straight pipe section 422, and then delivered to the receiving area 120 through the third straight pipe section 423 and the fourth straight pipe section 424. When it is necessary to clean the pipes or prevent residue, the first peristaltic pump 410 reverses, pushing the detergent retained in the third straight pipe section 423 and the fourth straight pipe section 424 back into the first receiving chamber 610.

[0044] Specifically, in one embodiment, the first peristaltic pump 410 can control the detergent flow rate P inside itself to satisfy 0.1 g / s ≤ P ≤ 1 g / s, preferably, P equals 0.5 g / s. It should be noted that the first peristaltic pump 410 can automatically adjust the detergent flow rate P according to its own power and orifice size.

[0045] Compared to existing technologies, traditional automatic dispensing boxes use a pump structure with a fixed flow rate, which can easily lead to pipe blockage or detergent waste due to excessive flow. This solution, however, achieves controllable quantitative delivery by limiting the flow range. For example, in existing technologies, the single dispensing flow rate may exceed 2.0 g / s, causing detergent to accumulate and clump in narrow pipes. This solution, on the other hand, controls the upper limit of the flow rate to below 1 g / s, effectively reducing the risk of pipe blockage and thus significantly improving maintainability and reliability.

[0046] Furthermore, in one embodiment, as Figure 7 As shown, the first connecting pipe assembly 420 includes a first straight pipe section 421, a second straight pipe section 422, a third straight pipe section 423, a fourth straight pipe section 424, and a first reinforcing beam 425. One end of the first straight pipe section 421 is connected to the first peristaltic pump 410, and the other end is connected to the second straight pipe section 422. The second straight pipe section 422 and the first straight pipe section 421 are arranged at an angle. The end of the second straight pipe section 422 away from the first straight pipe section 421 is connected to the liquid storage section 600. One end of the third straight pipe section 423 is connected to the first peristaltic pump 410, and the other end is connected to the fourth straight pipe section 424. The fourth straight pipe section 424 and the third straight pipe section 423 are arranged at an angle. The end of the fourth straight pipe section 424 away from the third straight pipe section 423 is connected to the receiving area 120. That is, the first peristaltic pump 410 draws detergent from the liquid storage section 600 through the second straight pipe section 422 and the first straight pipe section 421, and transmits the detergent to the receiving area 120 through the third straight pipe section 423 and the fourth straight pipe section 424. The first reinforcing beam 425 connects the first straight pipe section 421 and the third straight pipe section 423 to improve the structural strength of the first connecting pipe group 420.

[0047] Compared with existing technologies, this solution uses a split straight pipe section design, allowing users to replace only the faulty pipe section. The modular construction of the pipeline system significantly improves maintenance convenience, and disassembly can be completed without the need for professional tools.

[0048] However, this is not the only embodiment. In another embodiment, the first connecting pipe assembly 420 may also include two flexible hoses.

[0049] Furthermore, in one embodiment, such as Figure 6As shown, the first connecting pipe assembly 420 also includes a first sealing ring (not shown) and a second sealing ring 426. Multiple first sealing rings are spaced apart and fitted onto the second straight pipe section 422 to seal the gap between the second straight pipe section 422 and the liquid storage section 600. Multiple second sealing rings 426 are spaced apart and fitted onto the fourth straight pipe section 424 to seal the gap between the fourth straight pipe section 424 and the assembly body 300. This design, by arranging multiple first and second sealing rings 426 at intervals, ensures reliable sealing during assembly, reduces the risk of overall leakage due to the failure of a single first or second sealing ring 426, and simplifies the seal replacement operation during maintenance.

[0050] The dispensing assembly 400 also includes a second peristaltic pump 430 and a second connecting tube assembly 480. The second peristaltic pump 430 is connected to the second receiving cavity 630 and the receiving area 120 via the second connecting tube assembly 480. That is, when the second peristaltic pump 430 rotates forward, it can draw polishing agent from the second receiving cavity 630 into the receiving area 120; when the second peristaltic pump 430 rotates in reverse, it can transfer polishing agent from the second connecting tube assembly 480 into the second receiving cavity 630.

[0051] Similarly, the second peristaltic pump 430 extracts and returns the brightening agent through the fifth to eighth straight pipe sections. By controlling the forward and reverse rotation, the flow direction of the liquid within the pipes can be flexibly adjusted, preventing crystallization or blockage due to prolonged stagnation.

[0052] In one embodiment, the second peristaltic pump 430 can control the flow rate Q of the polishing agent inside it to satisfy 0.1 g / s ≤ Q ≤ 1 g / s, preferably, Q equals 0.5 g / s. It should be noted that the second peristaltic pump 430 can automatically adjust the flow rate Q of the polishing agent according to its own power and orifice size.

[0053] Further, in one embodiment, the second connecting pipe assembly 480 includes a fifth straight pipe section (not shown), a sixth straight pipe section (not shown), a seventh straight pipe section (not shown), an eighth straight pipe section (not shown), and a second reinforcing beam (not shown). One end of the fifth straight pipe section is connected to the second peristaltic pump 430, and the other end is connected to the sixth straight pipe section. The sixth straight pipe section and the fifth straight pipe section are arranged at an angle. The end of the sixth straight pipe section away from the fifth straight pipe section is connected to the liquid storage section 600. One end of the seventh straight pipe section is connected to the second peristaltic pump 430, and the other end is connected to the eighth straight pipe section. The eighth straight pipe section and the seventh straight pipe section are arranged at an angle. The end of the eighth straight pipe section away from the seventh straight pipe section is connected to the receiving area 120. That is, the second peristaltic pump 430 draws the brightening agent from the reservoir 600 through the sixth and fifth straight pipe sections, and transfers the brightening agent to the receiving area 120 through the seventh and eighth straight pipe sections. The second reinforcing beam connects the fifth and seventh straight pipe sections to improve the structural strength of the second connecting pipe assembly 480.
