Description

Technical Field

[0001] This utility model belongs to the technical field of dishwashers, and in particular relates to a dishwasher feeder box and a dishwasher. Background Technology

[0002] The dishwasher dispenser is an important component of the dishwasher, automatically adding detergent and / or rinse aid according to the dishwasher's operating requirements.

[0003] Currently, mainstream dishwasher dispensers, such as the one with patent publication number CN218105842U, use a transmission mechanism combined with a one-way flow valve to dispense detergent in a metered manner. However, in this design, the detergent's power relies on the reciprocating motion of a piston rod within the piston chamber. This mechanism requires the piston chamber to remain constantly connected to the outside atmosphere, resulting in prolonged and intense contact between the detergent and air. After prolonged periods of inactivity, the detergent is highly susceptible to crystallization due to moisture absorption or evaporation, leading to blockage of the flow channel and affecting the normal function and reliability of the dispenser. Utility Model Content

[0004] In view of this, it is necessary to provide a dishwasher feeder and a dishwasher for solving the above-mentioned technical problems.

[0005] A dishwasher feeder tray, comprising:

[0006] A liquid storage box has a liquid storage chamber inside, and an opening is formed on the liquid storage box, which communicates with the liquid storage chamber.

[0007] A dispenser housing is provided independently of the liquid storage box and connected to the liquid storage box. A liquid filling chamber is formed on the dispenser housing, which is in communication with the liquid storage chamber. A liquid outlet connector is also formed on the dispenser housing.

[0008] A sealing cap is disposed on the side of the dispenser housing opposite to the liquid storage box and is movably connected to the dispenser housing, for controlling the opening / closing of the liquid filling chamber;

[0009] A peristaltic pump is installed inside the dispenser housing and is connected to both the liquid storage chamber and the liquid outlet. The peristaltic pump can pump the medium from the liquid storage chamber to the liquid outlet and discharge the medium through the liquid outlet.

[0010] Understandably, using a peristaltic pump housed inside the dispenser box to control the pumping of the medium not only enables forward and reverse extraction of the medium when the dishwasher's feed box is in operation, but also effectively seals the liquid storage chamber when not in operation. This prevents the medium from contacting air and avoids crystallization problems caused by moisture absorption or evaporation, thereby improving the operational reliability and service life of the dishwasher's feed box. In addition, the dispenser and liquid storage tank are designed independently, making the dispenser versatile. This expands the adaptability of the dishwasher's feed box and reduces development and design costs.

[0011] In one embodiment, the peristaltic pump has a first operating state and a second operating state, and the peristaltic pump is capable of switching from the first operating state to the second operating state;

[0012] When the peristaltic pump is in the first working state, the peristaltic pump pumps the medium in the storage chamber to the outlet connector so that the medium is discharged from the outlet connector;

[0013] When the peristaltic pump is in the second operating state, the peristaltic pump can re-pump the retained medium from the outlet connector.

[0014] In one embodiment, the liquid outlet connector has a liquid outlet, and the liquid outlet connector is able to discharge the medium through the liquid outlet;

[0015] Furthermore, the liquid outlet is positioned vertically downwards.

[0016] Understandably, setting the liquid outlet of the drain connector vertically downwards can prevent splashing water from flowing back into the dishwasher's feed tray during operation, thus avoiding interference with the media stored in the feed tray.

[0017] In one embodiment, the sealing cap is capable of covering the liquid outlet connector;

[0018] When the sealing cap closes the liquid filling chamber, a cavity is formed between the sealing cap and the dispenser box. The cavity is used to accommodate the liquid outlet connector, and the medium discharged from the liquid outlet connector can be discharged outward through the cavity.

[0019] Understandably, sealing the drain connector with a cap further prevents water splashing during dishwasher operation from flowing back into the dishwasher's feed tray through the drain outlet.

[0020] In one embodiment, the dispenser housing is further provided with a liquid inlet connector, which can be inserted into the liquid storage box to communicate with the liquid storage chamber.

[0021] The peristaltic pump is connected to the inlet connector via a first hose; and the peristaltic pump is connected to the outlet connector via a second hose.

[0022] It is understandable that using a flexible tube to guide the inlet and outlet of the peristaltic pump facilitates its assembly and application within the distributor housing.

[0023] In one embodiment, the dispenser housing is further provided with a limiting protrusion and a limiting rib, the limiting protrusion being provided corresponding to the first hose, and the outer peripheral wall of the limiting protrusion abutting against and limiting the corresponding first hose.

[0024] The limiting rib is correspondingly provided with the peristaltic pump, and the limiting rib can abut against the corresponding peristaltic pump for limiting.

[0025] Understandably, using the upper limit protrusion and the limit rib on the dispenser box to limit the assembly of the first hose and the peristaltic pump respectively can prevent the hose from falling off due to excessive vibration during transportation, thus ensuring the normal use of the dishwasher's dispensing box.

[0026] In one embodiment, the number of liquid storage chambers is set to two, and the two liquid storage chambers are set independently of each other;

[0027] The number of peristaltic pumps is also set to two, with each of the two peristaltic pumps corresponding to one of the two liquid storage chambers, and the peristaltic pumps are connected to the corresponding liquid storage chambers.

[0028] Understandably, by utilizing the two liquid storage chambers of the liquid storage box, the dishwasher's feed box can have the function of storing two types of liquids. This not only avoids the need to add materials before each use of the dishwasher, making it more convenient to use, but also improves the space utilization rate of the two liquid storage chambers in the liquid storage box, which is conducive to expanding the liquid storage capacity of the dishwasher's feed box.

[0029] In one embodiment, the dispenser housing includes a lower dispenser cover and a higher dispenser cover, the lower dispenser cover being able to be inserted into the higher dispenser cover, and the lower dispenser cover and the higher dispenser cover being connected by a connector.

[0030] The peristaltic pump can be clamped and fixed by the lower cover and the upper cover of the dispenser.

[0031] This application also provides a dishwasher, including the dishwasher feed box described above.

[0032] In one embodiment, the dishwasher further includes a dishwasher door, the dispenser housing is disposed through the dishwasher door, and one end of the dispenser housing passing through the dishwasher door is connected to the liquid storage box; and the dispenser housing and the dishwasher door are assembled and sealed by a sealing gasket fitted on the dispenser housing.

[0033] The peristaltic pump is electrically connected to a cable assembly that extends outward from the side of the dishwasher door from the distributor housing.

[0034] Understandably, the above-mentioned structural design prevents water from entering the area where the peristaltic pump is located, thus preventing the peristaltic pump from short-circuiting and failing due to water leakage from the dishwasher, thereby ensuring the reliability of the peristaltic pump's operation.

[0035] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0036] The dishwasher feeder and dishwasher claimed in this application employ a peristaltic pump housed within the dispenser housing to control the extraction and discharge of the medium. This pump not only enables forward and reverse extraction of the medium during operation but also effectively seals the storage chamber when not in operation. This prevents the medium from contacting air and avoids crystallization caused by moisture absorption or evaporation, thereby improving the operational reliability and service life of the dishwasher feeder. Furthermore, the dispenser and storage tank are designed independently, making the dispenser versatile and expanding the adaptability of the dishwasher feeder, thus reducing development and design costs.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] like Figure 1 , Figure 2 As shown, the dishwasher unloading box 100 provided in this application includes a liquid storage box 10 and a dispenser 20. The liquid storage box 10 and the dispenser 20 are independently disposed, and the liquid storage box 10 abuts against and is connected to the dispenser 20. Specifically, it can be connected by multiple screws (not shown) that pass through the liquid storage box 10 and are screwed to the dispenser 20, making the dispenser 20 in the dishwasher unloading box 100 universal, while the liquid storage box 10 can be adaptively modified according to different storage amounts of the required storage medium. This expands the adaptability of the dishwasher unloading box 100 and reduces development and design costs. Here, the medium can specifically be detergent and / or rinse aid.

[0050] like Figures 1 to 7 As shown in this application, the liquid storage box 10 has a liquid storage chamber 101 inside, and an opening 102 is provided on the liquid storage box 10, which communicates with the liquid storage chamber 101. An exhaust pipe 103 is formed on the liquid storage box 10, which passes through the opening 102 and communicates with the liquid storage chamber 101. Specifically, the exhaust pipe 103 extends towards the distributor 20 and is inserted into the distributor housing 21 of the distributor 20. This allows the dishwasher feed box 100 of this application to use the exhaust pipe 103 to guide the gas in the liquid storage chamber 101 to be discharged during the process of adding media into the liquid storage chamber 101 of the liquid storage box 100. This ensures smooth addition of detergent and / or rinse aid, preventing liquid overflow due to air resistance. Furthermore, the exhaust pipe 103 can be integrally molded with the liquid storage box 10, simplifying the manufacturing process and eliminating subsequent assembly steps.

[0051] like Figure 3 As shown in this application, the liquid storage box 10 is provided with a flow-blocking rib 104 in the area where the liquid storage chamber 101 is located. The flow-blocking rib 104 and the liquid storage box 10 enclose a flow-guiding air chamber 105, which is set independently of the liquid storage chamber 101. The flow-guiding air chamber 105 has an air chamber inlet 1051 and an air chamber outlet 1052. The air chamber inlet 1051 is connected to the liquid storage chamber 101, and the air chamber outlet 1052 is connected to the exhaust pipe 103. In other words, the liquid storage box 10 of this application uses a guide air chamber 105 that is connected to the liquid storage chamber 101 only through the air chamber inlet 1051 to guide the gas. This can effectively guide the gas accumulated in the liquid storage chamber 101 to be discharged smoothly. This not only prevents the medium added to the liquid storage chamber 101 from entering the exhaust pipe 103 and ensures the smooth flow and exhaust efficiency of the exhaust pipe 103, but also ensures that the design of the exhaust pipe 103 will not interfere with the normal liquid storage function of the liquid storage chamber 101 on the liquid storage box 10, thus taking into account both exhaust performance and liquid storage stability.

[0052] like Figures 1 to 3 As shown in this application, the liquid storage box 10 includes a liquid storage box upper cover 11 and a liquid storage box lower cover 12. The liquid storage box upper cover 11 and the liquid storage box lower cover 12 are connected and sealed. Specifically, the liquid storage box upper cover 11 and the liquid storage box lower cover 12 can be connected by welding so that the liquid storage box upper cover 11 and the liquid storage box lower cover 12 enclose a liquid storage chamber.

[0053] Here, the opening 102 is provided on the upper cover 11 of the liquid storage box, and the exhaust pipe 103 is integrally injection molded on the upper cover 11 of the liquid storage box.

[0054] like Figure 3 As shown, the liquid storage box 10 of this application has two liquid storage chambers 101, which are independently arranged. This allows the dishwasher's feed box 100 to have a built-in function for storing two types of media. This not only avoids the need to add detergent before each use of the dishwasher, making it more convenient to use, but also improves the space utilization of the two liquid storage chambers 101 in the liquid storage box 10, which is beneficial to expanding the liquid storage capacity of the dishwasher's feed box 100. Here, one liquid storage chamber 101 is used to store detergent, and the other liquid storage chamber 101 is used to store rinse aid.

[0055] In this application, a float (not shown) is placed in the area of ​​the storage chamber 10 within the storage box 10. A magnetic element (not shown) is mounted on the float, allowing it to float on the surface of the medium within the storage chamber 101. Correspondingly, a Hall element 13 is positioned at the bottom of the storage chamber 101. The Hall element 13 can be triggered by the magnetic element on the float to generate a feedback signal. This allows the Hall element 13 to detect the liquid level of the medium within the storage chamber 101, achieving precise sensing of the liquid level and improving the accuracy and reliability of the detection results. Specifically, the magnetic element can be a magnet, a strong magnet, etc.

[0056] like Figure 1 , Figure 2 , Figures 4 to 7 As shown in this application, the dispenser 20 includes a dispenser housing 21, and the dispenser 20 is attached to and connected to the liquid storage box 10 via the dispenser housing 21. A liquid filling chamber 201 is formed on the dispenser housing 21, one end of which abuts and seals against the liquid storage box 10 and communicates with the opening 102. Furthermore, the portion of the exhaust pipe 103 extending out of the opening 102 is inserted into the liquid filling chamber 201. This eliminates the need for separate installation space for the exhaust pipe 103 in the dishwasher's unloading box 100, thereby reducing the overall volume required for the liquid storage box 10 when assembled inside the dishwasher. This helps to increase the effective volume of the dishwasher's inner drum and improve the overall space utilization rate.

[0057] like Figure 2 , Figure 4 and Figure 5 As shown, one of the liquid storage box 10 and the dispenser box 21 has a protruding positioning post 210, and the other has a recessed positioning groove 110. The positioning post 210 and the positioning groove 110 are correspondingly arranged, and the positioning post 210 can be inserted and engaged with the corresponding positioning groove 110 to assemble and position the liquid storage box 10 onto the dispenser box 21. This facilitates the assembly and connection between the liquid storage box 10 and the dispenser box 21, and is beneficial for the sealing between the liquid filling chamber 201 and the opening 102. Here, the positioning post 210 is integrated into the dispenser box 21. Specifically, a positioning post 210 can be formed at each of the four corners of the dispenser box 21. Correspondingly, the positioning groove 110 is provided on the liquid storage box cover 11 of the liquid storage box 10. It can be understood that in other embodiments, the positioning groove can also be provided on the dispenser box 21, and the positioning post can be provided on the liquid storage box 10. This will not be elaborated here.

[0058] like Figure 2 As shown in this application, an extended protrusion 106 is formed on the liquid storage box 10, which surrounds and forms an opening 102. The extended protrusion 106 can be inserted into the liquid filling chamber 201, and a sealing ring 107 seals the connection between the extended protrusion 106 and the liquid filling chamber 201. In other words, this application uses a sealing ring 107 to assemble and seal the inserted extended protrusion 106 and the liquid filling chamber 201, effectively ensuring the sealing performance at the connection between the liquid filling chamber 201 and the opening 102. This not only prevents leakage of the medium from the connection between the liquid filling chamber 201 and the opening 102 during the filling process, but also prevents external contaminants from entering the liquid storage chamber 101 of the liquid storage box 10, thereby improving the reliability and cleanliness of the medium filling process.

[0059] like Figure 4 , Figure 5 As shown, the dispenser housing 21 includes a lower dispenser cover 211 and an upper dispenser cover 212. The lower dispenser cover 211 can be inserted and engaged with the upper dispenser cover 212. The lower dispenser cover 211 and the upper dispenser cover 212 are connected by a connector (not shown). Specifically, multiple screws can be used to achieve the assembly connection between the lower dispenser cover 211 and the upper dispenser cover 212.

[0060] like Figure 1 , Figure 2 , Figures 3 to 6 As shown, the dispenser 20 also includes a sealing cover 22, which is disposed on the side of the dispenser housing 21 away from the liquid storage box 10 and is movably connected to the dispenser housing 21. It is used to selectively cover and seal the liquid filling chamber 201 and control the opening / closing of the liquid filling chamber 201.

[0061] Here, one side of the sealing cover 22 is rotatably mounted on the distributor cover 212 of the distributor housing 21 via a pivot (not shown), and the sealing cover 22 can be connected and fixed to the distributor cover 212 by snap-fit; and when the sealing cover 22 is snapped to the distributor cover 212, the sealing cover 22 can seal the other end opening of the liquid filling chamber 201.

[0062] like Figure 4 , Figure 5 As shown, a liquid outlet connector 202 is also formed on the dispenser housing 21, and the dispenser 20 can discharge the medium stored in the liquid storage chamber 101 through the liquid outlet connector 202; wherein, the sealing cover 22 can cover the liquid outlet connector 202; and when the sealing cover 22 closes the liquid filling chamber 201, a cavity 220 is formed between the sealing cover 22 and the dispenser housing 21, the cavity 220 is used to accommodate the liquid outlet connector 202, and the medium discharged from the liquid outlet connector 202 can be discharged out through the cavity 220, so that the sealing cover 22 can cover the liquid outlet connector 202, which can further prevent the water splashed during the operation of the dishwasher from flowing back into the liquid storage chamber 101 of the dishwasher unloading box 100 through the liquid outlet connector 202.

[0063] like Figure 4 , Figure 5 As shown, the liquid outlet connector 202 has a liquid outlet 2021, and the liquid outlet connector 202 can discharge the medium through the liquid outlet 2021; in addition, the liquid outlet 2021 is set vertically downward, which can prevent the water splashed during the operation of the dishwasher from flowing back into the dishwasher feed box 100 through the liquid outlet, and avoid interfering with the medium stored in the dishwasher feed box 100.

[0064] like Figure 6 , Figure 7 As shown, in this application, the distributor 20 also includes a peristaltic pump 23, which is installed inside the distributor housing 21 and is connected to the liquid storage chamber 101 and the liquid outlet connector 202 respectively. The peristaltic pump 23 can pump the medium in the liquid storage chamber 101 to the liquid outlet connector 202, and discharge the medium through the liquid outlet connector 202. In other words, the distributor 20 of this application uses a peristaltic pump 23 housed inside the distributor housing 21 to control the pumping and discharging of the medium. This not only enables forward and reverse pumping of the medium when the dishwasher unloading box 100 is working, but also effectively seals the liquid storage chamber 101 when not in operation. This prevents the medium from contacting air and avoids crystallization problems caused by moisture absorption or evaporation, thereby improving the operational reliability and service life of the dishwasher unloading box 100.

[0065] Here, the peristaltic pump 23 can be clamped and fixed by the lower cover 211 and the upper cover 212 of the distributor; wherein, the peristaltic pump 23 has a first working state and a second working state, and the peristaltic pump 23 can switch from the first working state to the second working state; when the peristaltic pump 23 is in the first working state, the peristaltic pump 23 pumps the medium in the storage chamber 101 to the outlet connector 202 so that the outlet connector 202 discharges the medium; when the peristaltic pump 23 is in the second working state, the peristaltic pump 23 can re-pump the retained medium from the outlet connector 202.

[0066] like Figures 4 to 7 As shown, a liquid inlet connector 2111 is also formed on the distributor housing 21. The liquid inlet connector 2111 can be inserted and mated with the liquid storage box 10 to communicate with the liquid storage chamber 101. The peristaltic pump 23 is connected to the liquid inlet connector 2111 via a first flexible hose 231, and the peristaltic pump 23 is connected to the liquid outlet connector 202 via a second flexible hose 232. That is to say, this application uses flexible hoses to guide the liquid inlet and outlet of the peristaltic pump 23, which facilitates the assembly and application of the peristaltic pump 23 in the distributor housing 21.

[0067] like Figure 7 As shown, the dispenser box 21 also has a limiting protrusion 203 and a limiting rib 204. The limiting protrusion 203 is correspondingly arranged with the first hose 231, and the outer peripheral wall 2031 of the limiting protrusion 203 abuts against the corresponding first hose 231 for limiting. The limiting rib 204 is correspondingly arranged with the peristaltic pump 23, and the limiting rib 204 can abut against the corresponding peristaltic pump 23 for limiting, and realize the assembly limiting of the first hose 231 and the peristaltic pump 23. This can prevent the hose from falling off due to excessive vibration during the transportation of the dishwasher discharge box 100, thereby ensuring the normal use of the dishwasher discharge box 100.

[0068] In addition, this application also provides a dishwasher, including the dishwasher feed box 100 described above.

[0069] In this application, the dishwasher also includes a dishwasher door (not shown), a dispenser box 21 extending through the dishwasher door, and one end of the dispenser box 21 passing through the dishwasher door is connected to the liquid storage box 10; furthermore, the dispenser box 21 and the dishwasher door are sealed together by a sealing gasket 300 fitted on the dispenser box 21. That is, in this application, the liquid storage box 10 is located on the outside of the dishwasher door, so that when the dishwasher door is closed and the dishwasher inner tub is closed, the dishwasher discharge box 100 is vertical; and when the dishwasher door is open and the dishwasher inner tub is open, the dishwasher discharge box 100 is horizontal. At this time, the liquid filling chamber 201 can be opened by driving the sealing cover 22, and the medium can be added into the liquid storage chamber 101 of the liquid storage box 10.

[0070] Here, the peristaltic pump 23 is electrically connected to a cable assembly (not shown). The cable assembly extends outward from the side of the dishwasher door from the distributor box 21, which makes the peristaltic pump 23 and the dishwasher inner tub a non-contact structure. This prevents the peristaltic pump 23 from short-circuiting due to water leakage from the dishwasher, thus ensuring the reliability of the peristaltic pump 23.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
