[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0039] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0040] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0041] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0042] This application embodiment provides a detergent dispensing device, which includes a dispenser box and a water circuit board 10 (e.g., Figure 2 (As shown). The water circuit board 10 is located above the distributor box. The water circuit board 10 has a water inlet channel 11, which is connected to an external water source and can discharge water toward the distributor box.

[0043] For example, the up and down direction is Figure 1 The directions indicated include both top-down and bottom-up directions. The top-down direction is also the height direction.

[0044] For example, Figure 3 and Figure 4 The dotted line in the diagram indicates a portion of the water inlet channel 11, and the arrow indicates the approximate flow direction of the liquid within the water inlet channel 11.

[0045] In some embodiments, the detergent dispensing device further includes a functional component disposed in the dispenser box, which releases a functional substance upon contact with the liquid flowing through it. In this embodiment, the water channel plate 10 is also located above the functional component.

[0046] The structure of the functional component is not limited. For example, the functional component includes a housing and a sustained-release unit, with the sustained-release unit housed within the housing and containing various active ingredients. The housing wall has a connecting hole, which allows liquid to enter the interior of the housing through the connecting hole to flush the sustained-release unit, and also allows the functional substances released by the sustained-release unit to flow out with the liquid to the outside of the housing.

[0047] For example, the outer casing is cylindrical.

[0048] For example, the sustained-release unit is in block form.

[0049] For example, the sustained-release unit has multiple through holes so that liquid can enter the interior of the sustained-release unit through the multiple through holes to dissolve the active ingredients in the sustained-release unit, thereby allowing the sustained-release unit to release the functional substances.

[0050] It should be noted that the type of functional substances is not limited. The released functional substances can include, but are not limited to, substances used for sterilization, disinfection, fragrance enhancement, stain removal, and removal of special stains on clothing. For example, functional components can release metal ions such as silver ions or complex cations into the liquid flowing through them, which helps improve the sterilization effect of clothing. Functional components can also release herbal extracts such as peony root extract or plant active factors into the liquid flowing through them, which helps improve the antibacterial effect. Furthermore, functional components can release water purification substances such as dynamic scale inhibitors or water softening agents into the liquid flowing through them, which can adsorb calcium and magnesium ions in the liquid, reduce scale formation, and help reduce the chance of hard water damaging clothing fibers and the chance of scale clogging liquid channels. Finally, functional components can release slow-release cleaning agents or antioxidants into the liquid flowing through them, which helps reduce the chance of clothing fiber damage and delay fading and aging of clothing.

[0051] For example, please refer to Figure 3 and Figure 4The inlet channel 11 has a first outlet area 112 and a second outlet area 111 on its flow path. The first outlet area 112 is located upstream or downstream of the second outlet area 111. The bottom wall of the first outlet area 112 is provided with at least one first outlet hole 1121, and the bottom wall of the second outlet area 111 is provided with at least one second outlet hole 1111.

[0052] The first water outlet 1121 guides liquid to the functional component below the water circuit board 10. Liquid flowing from the first water outlet 1121 flows towards the functional component, rinsing it and causing the component to release functional substances into the liquid. These functional substances help improve the washing and care effect on clothes. Furthermore, the first water outlet area 112 and the second water outlet area 111 are located on the same water inlet channel 11, requiring only one water inlet channel 11 to achieve both water inlet and other functions, resulting in a simple structure. The connection method between the functional component and the dispenser box is not limited.

[0053] For example, the dispenser box has a first slot in which the functional component is received. In this way, the functional component can be stably placed in the first slot without the need for a complex connection structure.

[0054] For example, the functional component is detachably disposed in the first slot, that is, the functional component is detachably disposed in the dispenser box, so as to facilitate the removal and placement of the functional component.

[0055] In some embodiments, the dispenser box has a second compartment for holding detergent. The detergent may be laundry liquid, fabric softener, disinfectant, perfume, etc.

[0056] For example, the second water outlet 1111 is used to guide liquid into a second tank below the cover 10. The liquid flowing out of the second water outlet 1111 flows into the second tank, flushing and dissolving the detergent in the second tank to form a detergent mixture. For example, the detergent mixture flows into the mixing tank 21 described below. That is, before each wash, the user needs to add detergent to the second tank, and the amount of detergent added at one time is sufficient for a single wash. This method of adding detergent can also be called manual addition.

[0057] In other words, in this embodiment, the detergent dispensing device can not only provide detergent mixture, but also functional substances other than detergent mixture, which helps to further improve the washing and care effect of clothes.

[0058] In some embodiments, the first outlet region 112 is located upstream of the second outlet region 111. That is, the fluid in the inlet channel 11 flows through the first outlet region 112 first, and then through the second outlet region 111. In this way, a portion of the fluid in the inlet channel 11 is diverted from the first outlet hole 1121, which helps to reduce the pressure and velocity of the fluid flowing to the second outlet region 111, allowing the liquid to flow to the second tank at a relatively gentle flow rate, and reducing the splashing phenomenon generated when the fluid flows through the second tank.

[0059] Of course, in other embodiments, the first water outlet region 112 may also be located downstream of the second water outlet region 111.

[0060] In some embodiments, the total cross-sectional area of ​​the second water outlet holes 1111 in the second water outlet region 111 is larger than the total cross-sectional area of ​​the first water outlet holes 1121 in the first water outlet region 112. This helps to ensure that the flow rate of liquid from the second water outlet region 111 to the second tank is greater than the flow rate of liquid from the first water outlet region 112 to the functional component. On the one hand, the flow rate of liquid to the second tank is larger to meet the detergent dissolution requirements in the second tank; on the other hand, the flow rate of liquid to the functional component is smaller, allowing a small amount of liquid to continuously permeate, enabling the functional component to slowly release the functional substance.

[0061] In the embodiment where the first water outlet area 112 is located upstream of the second water outlet area 111, when the liquid in the water inlet channel 11 passes through the first water outlet area 112, the flow rate of the liquid discharged from the first water outlet area 112 through the first water outlet hole 1121 is relatively small, so that more liquid in the water inlet channel 11 can flow to the downstream second water outlet area 111 and then be discharged towards the second tank through the second water outlet hole 1111.

[0062] It should be noted that the total cross-sectional area of ​​the first water outlet hole 1121 in the first water outlet area 112 refers to the sum of the cross-sectional areas of all the first water outlet holes 1121.

[0063] Similarly, the total cross-sectional area of ​​the second water outlet hole 1111 in the second water outlet area 111 refers to the sum of the cross-sectional areas of all the second water outlet holes 1111.

[0064] Please see Figure 1 The detergent dispensing device includes a box body 20 and a water channel plate 10 located on the top side of the box body 20. Together, they enclose a space for accommodating the dispenser box.

[0065] Specifically, the housing 20 has a mixing tank 21 located below the dispenser housing. Thus, the functional substance flows into the mixing tank 21 along with the liquid exiting the first water outlet 1121. The detergent mixture flows into the mixing tank 21.

[0066] For example, the housing 20 has a pull-out opening 22 through which the dispenser box can be pulled out. That is, the dispenser box is pulled out and disposed inside the housing 20. When the user needs to add detergent to the second tank, the dispenser box is pulled out from the pull-out opening 22, detergent is added to the second tank, and then the dispenser box is pushed back into the housing 20.

[0067] In an embodiment where the functional component is detachably disposed in the dispenser box, the functional component is pulled out and disposed within the box body 20 along with the dispenser box, so that the functional component can be removed when the dispenser box is in the pulled-out state for cleaning, maintenance, replacement, etc.

[0068] In some embodiments, the water circuit board 10 is provided with at least one drain hole 12, which is connected to the water inlet channel 11 and is used to guide a portion of the liquid in the water inlet channel 11 to the mixing tank 21. By providing the drain hole 12, a portion of the liquid in the water inlet channel 11 can be drained into the mixing tank 21, which helps to maintain the liquid pressure inside the cover 10.

[0069] For example, the drain hole 12 is located downstream of the second outlet area 111 and the first outlet area 112. In this way, liquid that flows through the second outlet area 111 and the first outlet area 112 and is not discharged flows through the drain hole 12 to the mixing tank 21, so as to minimize the impact of the drain hole 12 on the flow rate of liquid in the second outlet area 111 and the first outlet area 112.

[0070] For example, the housing 20 has a liquid outlet 211 communicating with the mixing tank 21, the liquid outlet 211 being used to discharge the liquid in the mixing tank 21 to the outside of the housing 20, for example, to the bellows described below.

[0071] For example, the second tank is provided with a first opening that communicates with the mixing tank 21, so that the liquid discharged from the second water outlet 1111 is mixed with the detergent in the second tank and discharged into the mixing tank 21 through the first opening.

[0072] For example, the first tank is provided with a second opening that communicates with the mixing tank 21, so that the liquid discharged from the first water outlet 1121 washes the functional component and the functional substance released by the functional component is discharged into the mixing tank 21 along with the liquid through the second opening.

[0073] During the washing process, part of the liquid in the water inlet channel 11 flows through the second outlet 1111 and then through the second tank to the mixing tank 21, part of the liquid flows through the first outlet 1121 and then through the functional component to the mixing tank 21, and another part enters the mixing tank 21 through the drain hole 12. The liquid in the mixing tank 21 flows to the outside of the box 20 through the liquid outlet 211, such as the corrugated pipe mentioned below.

[0074] In some embodiments, at least one drain hole 12 includes a first drain hole 121 and a second drain hole 122, which are arranged at intervals along the fluid flow direction of the water inlet channel 11, with the second drain hole 122 located upstream of the first drain hole 121. This facilitates stepwise pressure relief.

[0075] In some embodiments, the projection of the drain hole 12 onto a plane perpendicular to the height of the detergent dispenser 1 is outside the projected outline of the dispenser box. This minimizes the contact between the liquid drained from the drain hole 12 and the dispenser box. On the one hand, it prevents liquid falling from the drain hole 12 from seeping out through the gap between the dispenser box and the pull-out opening 22; on the other hand, it prevents excessive liquid from adhering to the outer wall of the dispenser box when the user pulls it out of the pull-out opening 22.

[0076] In some embodiments, when projected onto a plane perpendicular to the height of the detergent dispenser 1, the projection of at least one drain hole 12 is located on the side of the dispenser dispenser away from the pull-out opening 22. This allows some of the liquid from the water inlet channel 11 to fall through the drain hole 12, thus flushing the detergent residue on the inner wall of the mixing tank 21 and effectively rinsing the inner wall of the mixing tank 21.

[0077] In some embodiments, please refer to Figure 4 and Figure 5 The detergent dispensing device includes a flow-blocking component 5 disposed in the water inlet channel 11. At least one end of the flow-blocking component 5 (hereinafter referred to as the first end 51) is connected to the wall of the water inlet channel 11, and the other end (hereinafter referred to as the second end 52) extends obliquely upstream in the direction of fluid flow.

[0078] Understandably, since the first end 51 of the flow-blocking assembly is connected to the wall, fluid cannot flow through the connection between the flow-blocking assembly 5 and the corresponding wall (i.e., the wall connected to the first end 51). The wall provides support and fixation for the flow-blocking assembly 5, ensuring its stability within the water inlet channel 11.

[0079] Please refer to Figure 5The second end 52 extends obliquely upstream in the direction of fluid flow. It is understood that a channel (which is part of the water inlet channel 11) is generally formed between the flow-blocking component 5 and another wall surface, widening from narrow to wide along the flow direction. When the fluid flows through this channel, its velocity is reduced. Furthermore, due to the obstruction of the flow-blocking component 5, some fluid flows backward a short distance. During this process, the backward-flowing fluid impacts the forward-flowing fluid, which also helps to reduce the velocity. In some embodiments, the detergent dispensing device includes a pump 2, and the dispenser box has a storage chamber for storing detergent. The pump 2 is used to extract detergent from the storage chamber. Thus, the pump 2 can quantitatively extract detergent from the storage chamber, facilitating automatic detergent dispensing. In other words, the detergent dispensing device of this application embodiment has both automatic and manual dispensing functions.

[0080] It should be noted that the storage chamber and the second tank are not connected. That is, the detergent in the second tank and the detergent in the storage chamber do not affect each other.

[0081] In some embodiments, the pump 2 draws in detergent and discharges it into the mixing tank 21. The detergent dissolves and mixes in the mixing tank 21. In other embodiments, the pump 2 may also pump the detergent into a mixing zone within the water channel plate 10. This mixing zone is located on a separate water channel that is not connected to the water channel flowing to the second tank. After the detergent dissolves and mixes in the mixing zone, it flows through a pipe connected to the cover 10 to the nozzle and is sprayed out through the nozzle. Exemplarily, the nozzle may be located in the door seal ring described below.

[0082] For example, the detergent dispensing device includes a flushing pipe 3, which connects to the water inlet channel 11 and the inner cavity of the liquid pump 2, for guiding liquid into the inner cavity of the liquid pump 2 to clean the inner cavity of the liquid pump 2. This achieves cleaning of the inner cavity of the liquid pump 2 and reduces the likelihood of bacterial growth inside the liquid pump 2.

[0083] Specifically, when the pump 2 draws in detergent, the detergent enters the inner cavity and is then pumped out. It is understood that the liquid in the flushing line 3 enters the inner cavity of the pump 2 in a unidirectional manner; that is, the liquid in the inner cavity of the pump 2 will not flow back into the flushing line 3.

[0084] In some embodiments, a spray channel 13 is also formed inside the cover 10. One end of the spray channel 13 is connected to the water inlet channel 11, and the other end of the spray channel 13 is used to connect to the spray pipe 4. In this way, a portion of the liquid in the water inlet channel 11 flows to the spray pipe 4 through the spray channel 13.

[0085] For example, the outlet end of the spray pipe 4 may be located at the door seal ring described below.

[0086] This application also provides a garment processing device, which includes a drum assembly and a detergent dispensing device as described in any embodiment of this application. The detergent dispensing device is used to supply liquid to the drum assembly.

[0087] The clothing treatment equipment provided in this application embodiment achieves the washing function of clothing through the detergent mixture provided by the detergent dispensing device. The functional substances other than the detergent mixture provided by the detergent dispensing device help to improve the washing and care effect of clothing.

[0088] The specific type of clothing processing equipment is not limited; for example, it can be a washing machine, a washer-dryer combo, etc.

[0089] For example, the cylindrical assembly includes an outer tub and an inner tub, with the inner tub rotatably disposed inside the outer tub. That is, the outer tub is fitted over the inner tub. The outer tub is used to hold water, and the inner tub is used to hold clothing. In this embodiment, the inner tub holds water through the outer tub, and the inner tub can also be referred to as a perforated inner tub.

[0090] In some embodiments, the garment handling equipment includes a corrugated pipe that connects the outer tub and the liquid outlet 211.

[0091] In some embodiments, the garment handling device includes a door seal ring located at the front end of the bobbin assembly.

[0092] For example, the outlet end of the spray pipe 4 is located at the door seal ring.

[0093] In some embodiments, the garment handling apparatus includes a door and a door glass, the door glass being located on the side of the door facing the garment handling chamber. The spray pipe 4 can spray liquid at least toward the door glass of the door to clean it.
