Description

Technical Field

[0001] This invention belongs to the field of clothing treatment technology, specifically relating to a detergent dissolving device, a detergent box, and clothing treatment equipment. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Clothing handling equipment is one of the most commonly used household appliances in daily life. Clothing handling equipment usually includes washing equipment, drying equipment, and washer-dryer combos. Washing equipment usually includes top-loading washing machines and front-loading washing machines. Front-loading washing machines are generally equipped with a detergent dispenser, which is used to add laundry powder or liquid detergent into the drum of the washing machine.

[0004] The existing method of dissolving detergent in drum washing machines is as follows: laundry powder or liquid is put into the detergent dispenser, water enters the detergent dispenser and impacts the laundry powder or liquid, and after the laundry powder or liquid is dissolved, it flows into the drum from the outlet. This method of dissolving cannot fully dissolve the laundry powder or liquid, resulting in problems such as residual laundry powder particles or uneven entry of laundry liquid into the drum, thus affecting the washing effect on clothes. Summary of the Invention

[0005] The objective of this invention is to at least solve the problem of insufficient detergent dissolution in existing laundry processing equipment. This objective is achieved through the following technical solution:

[0006] The first aspect of the present invention provides a detergent dissolving device, the detergent dissolving device comprising:

[0007] A detergent containing structure, the detergent containing structure having a containing cavity, and a first dispensing nozzle extending from the detergent containing structure and communicating with the containing cavity;

[0008] A spiral water injection structure is connected to the bottom of the detergent container structure. The spiral water injection structure includes a spiral flow channel and a dissolving chamber. The outlet of the spiral flow channel is connected to the dissolving chamber. The first liquid outlet extends into the outlet and into the dissolving chamber, communicating with the dissolving chamber.

[0009] According to an embodiment of the present invention, the detergent dissolving device has a receiving cavity in the detergent receiving structure for holding detergent or detergent solution, a first outlet for guiding the detergent or detergent solution in the receiving cavity into the dissolving cavity, and a spiral flow channel in the spiral water injection structure for guiding water spirally into the dissolving cavity. In this embodiment, the detergent receiving structure and the spiral water injection structure are connected, wherein the first outlet extends into the outlet of the spiral flow channel and communicates with the dissolving cavity. That is, the detergent or detergent solution flowing out from the first outlet and the water flowing out from the spiral flow channel come into contact and mix during the process of flowing into the dissolving cavity. Moreover, since the water in the spiral flow channel flows out in a vortex shape, the impact force of the water is large, thereby increasing the mixing intensity of water and detergent or detergent solution, and thus improving the dissolving effect. Furthermore, the water and detergent or detergent solution are further mixed after entering the dissolving cavity, thereby further dissolving. In summary, the detergent dissolving device proposed in this embodiment can be applied to clothing processing equipment to improve the dissolving effect of detergent and solve the problem of insufficient detergent dissolution in existing clothing processing equipment.

[0010] In addition, the detergent dissolving device according to the embodiments of the present invention may also have the following technical features:

[0011] In some embodiments of the present invention, the bottom surface of the receiving cavity is configured as a slope that gradually slopes downward from the edge toward the center, and the first liquid outlet is connected to the central region of the bottom of the receiving cavity.

[0012] In some embodiments of the present invention, the spiral channel is arranged in a horizontal direction, the outlet is arranged in the central region of the spiral channel, and the first liquid outlet extends vertically into the outlet and is coaxially arranged with the outlet.

[0013] In some embodiments of the present invention, the cross-sectional area of ​​the outermost flow channel of the spiral flow channel is larger than the cross-sectional area of ​​the innermost flow channel.

[0014] In some embodiments of the present invention, the cross-sectional area of ​​the spiral channel decreases sequentially from the outermost channel to the innermost channel.

[0015] In some embodiments of the present invention, the bottom surface of the spiral flow channel is configured as an inclined surface that gradually slopes downward from the edge toward the center, and the dissolving cavity is located in the central region of the bottom of the spiral water injection structure.

[0016] In some embodiments of the present invention, the dissolving chamber is configured as a funnel shape, and there is a gap between the bottom end of the first dispensing nozzle and the side wall of the dissolving chamber.

[0017] In some embodiments of the present invention, the spiral water injection structure further includes a second liquid outlet, which is disposed at the bottom of the dissolving chamber and communicates with the dissolving chamber.

[0018] In some embodiments of the present invention, the detergent containing structure is integrally formed with the spiral water injection structure.

[0019] A second aspect of the present invention provides a detergent dispenser, the detergent dispenser comprising:

[0020] A lid, wherein the lid is provided with a water inlet and a spray nozzle that are connected to each other;

[0021] The box body is connected to the box lid, and the box body is provided with a detergent dispensing chamber located below the spray nozzle;

[0022] According to any of the above embodiments, the detergent dissolving device is connected to the housing and communicates with the detergent dispensing chamber, and the receiving chamber of the detergent dissolving device is located downstream of the detergent dispensing chamber.

[0023] According to an embodiment of the present invention, the detergent dispenser has a detergent dispensing chamber for dispensing detergent. External water can enter the lid through the water inlet and spray out from the spray nozzle to initially dissolve the detergent. The detergent dissolving device is located downstream of the detergent dispensing chamber, so the detergent solution flowing out of the detergent dispensing chamber flows into the receiving chamber of the detergent containing structure and can flow out from the first outlet, thereby contacting and mixing with the water flowing out from the spiral channel as it flows into the dissolving chamber, achieving a second dissolution. Since the water flowing out of the spiral channel is in a vortex shape, the water has a large impact force, thereby increasing the mixing intensity of water and detergent solution during the second dissolution process, further improving the dissolution effect. After the water and detergent solution enter the dissolving chamber, they mix further. In summary, the detergent dispenser proposed in this embodiment can be applied to clothing processing equipment to improve the dissolution effect of detergent and solve the problem of insufficient detergent dissolution in existing clothing processing equipment.

[0024] In some embodiments of the present invention, the bottom surface of the detergent dispensing chamber is configured as an inclined surface that gradually slopes downward in the direction pointing towards the detergent dissolving device.

[0025] In some embodiments of the present invention, the box body is further provided with an overflow channel, the overflow channel is flush with the highest water level of the receiving cavity and communicates with the receiving cavity, and the overflow channel is used to communicate with the outer tub of the clothing processing equipment.

[0026] In some embodiments of the present invention, the box body is integrally formed with the detergent dissolving device.

[0027] A third aspect of the present invention provides a garment processing device, the garment processing device comprising an inner tub, an outer tub, and a detergent dispenser according to any of the above embodiments, wherein the detergent dissolving device of the detergent dispenser is connected to the inner tub.

[0028] According to the clothing treatment device of the present invention, the detergent dispensing chamber of the detergent box is used to dispense detergent. Water entering the box cover through the water inlet and spraying out from the spray nozzle can initially dissolve the detergent. The detergent dissolving device located downstream of the detergent dispensing chamber can perform secondary dissolution of the detergent solution. Furthermore, by setting a spiral water injection structure, the mixing intensity of water and detergent solution during the secondary dissolution process is improved, further enhancing the dissolution effect. Therefore, the detergent in the clothing treatment device proposed in this embodiment is more fully dissolved, solving the problem of insufficient detergent dissolution in existing clothing treatment devices.

[0049] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0050] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

[0051] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0052] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0053] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a detergent dissolving device 100, which includes a detergent containing structure 10 and a spiral water injection structure 20. The detergent containing structure 10 has a containing cavity 11, and a first liquid outlet 12 extending from the detergent containing structure 10 and communicating with the containing cavity 11 is provided. The spiral water injection structure 20 is connected to the bottom of the detergent containing structure 10, and the spiral water injection structure 20 includes a spiral flow channel 21 and a dissolving cavity 22. The water outlet 212 of the spiral flow channel 21 communicates with the dissolving cavity 22, and the first liquid outlet 12 extends into the water outlet 212 and extends into the dissolving cavity 22 and communicates with the dissolving cavity 22.

[0054] In the detergent dissolving device 100 proposed in this embodiment of the invention, the receiving cavity 11 of the detergent receiving structure 10 is used to hold detergent or detergent solution, the first outlet 12 is used to guide the detergent or detergent solution in the receiving cavity 11 into the dissolving cavity 22, and the spiral flow channel 21 in the spiral water injection structure 20 is used to guide the water spiral flow into the dissolving cavity 22. In this embodiment, the detergent receiving structure 10 and the spiral water injection structure 20 are connected, wherein the first outlet 12 extends into the outlet 212 of the spiral flow channel 21 and communicates with the dissolving cavity 22. That is to say, the detergent or detergent solution flowing out from the first outlet 12... The detergent solution and the water flowing out of the spiral channel 21 come into contact and mix as they flow into the dissolving chamber 22. Moreover, because the water flows out of the spiral channel 21 in a vortex shape, the impact force of the water is relatively large, thereby increasing the mixing intensity of the water and the detergent or detergent solution, and thus improving the dissolving effect. Furthermore, the water and the detergent or detergent solution mix further after entering the dissolving chamber 22, thereby further dissolving. In summary, the detergent dissolving device 100 proposed in this embodiment can be applied to clothing processing equipment to improve the dissolving effect of detergent and solve the problem of insufficient detergent dissolution in existing clothing processing equipment.

[0055] Specifically, please refer to Figure 1 , Figure 1 This is a schematic diagram of the detergent dissolving device 100 according to an embodiment of the present invention. In this embodiment, the detergent containing structure 10 is connected to the spiral water injection structure 20, and the spiral water injection structure 20 is located below the detergent containing structure 10. The detergent containing structure 10 and the spiral water injection structure 20 can be connected by adhesive or snap-fit. Alternatively, in some embodiments of the present invention, the detergent containing structure 10 and the spiral water injection structure 20 are integrally formed, specifically by integral injection molding, which is convenient for manufacturing. The spiral flow channel 21 can be spirally arranged in the horizontal direction, or in the vertical direction or in an inclined direction at an acute angle to the horizontal direction, as long as the water in the spiral flow channel 21 can spirally flow out and come into contact with and mix with the detergent or detergent solution.

[0056] In this embodiment, the receiving cavity 11 is used to hold detergent or detergent solution. It should be noted that the detergent dissolving device 100 proposed in this embodiment can be directly applied to clothing processing equipment. In this case, the user can directly put the detergent into the receiving cavity 11. Alternatively, the detergent dissolving device 100 can be installed in the detergent box 1000. Based on the detergent box 1000 itself having a dispensing cavity, the detergent in the dispensing cavity forms a detergent solution after being initially dissolved by mixing with water. In this case, the detergent solution can flow into the receiving cavity 11 of this embodiment for further dissolution.

[0057] Specifically, taking the horizontal plane as the cross-section, the cross-sectional shape of the detergent-containing structure 10 can be set to rectangular, circular, or elliptical, and the cross-sectional shape of the spiral water injection structure 20 can be set to circular or elliptical to facilitate the setting of the internal spiral flow channel 21. In an optional embodiment, such as... Figure 1 As shown, the cross-sectional shape of the detergent holding structure 10 and the spiral water injection structure 20 is set to be circular. Based on this, the bottom surface of the holding cavity 11 of the detergent holding structure 10 is circular, and the first liquid outlet 12 extends out and is disposed on the detergent holding structure 10. It can be understood that the first liquid outlet 12 is located at the bottom of the detergent holding structure 10 so as to communicate with the dissolving cavity 22 of the spiral water injection structure 20.

[0058] Please see Figure 2 , Figure 2 for Figure 1 The shown is a cross-sectional view along the A-A direction of the detergent dissolving device 100. In some embodiments of the present invention, the bottom surface of the receiving cavity 11 is set as an inclined surface, such as... Figure 2 As shown, the bottom surface of the receiving cavity 11 gradually slopes downward from the edge towards the center. That is, the center of the bottom of the receiving cavity 11 is the lowest point of the receiving cavity 11. When the receiving cavity 11 contains detergent or detergent solution, the detergent or detergent solution tends to flow towards the center of the bottom. Based on this, in this embodiment, the first dispensing nozzle 12 is connected to the central area of ​​the bottom of the receiving cavity 11. It can be understood that the first dispensing nozzle 12 is connected to the receiving cavity 11, and the detergent or detergent solution in the receiving cavity 11 can flow out from the first dispensing nozzle 12. In this embodiment, by setting the bottom surface of the receiving cavity 11 as a slope and setting the first dispensing nozzle 12 in the central area of ​​the bottom of the receiving cavity 11, the speed at which the detergent or detergent solution flows out from the first dispensing nozzle 12 is further improved.

[0059] Based on the above embodiments, the bottom surface of the receiving cavity 11 is set as a smooth slope to reduce the obstruction to the flow of detergent or detergent solution. Furthermore, the first dispensing nozzle 12 can be cylindrical. When the cross-sectional shape of the receiving cavity 11 is circular, the axis of the first dispensing nozzle 12 can coincide with the axis of the receiving cavity 11. The first dispensing nozzle 12 is integrally formed on the bottom of the receiving cavity 11, and the bottom plate of the receiving cavity 11 and the side wall of the first dispensing nozzle 12 are configured with a smooth transition structure to avoid affecting the flow of detergent or detergent solution.

[0060] Please continue reading. Figure 2 and in conjunction with reference Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the flow path of liquid in the detergent dissolving device 100 of this embodiment of the invention. Figure 4 for Figure 3 A schematic diagram of the three-dimensional structure. Figure 3 and Figure 4 The arrows indicate the flow direction of the liquid in the detergent dissolving device 100. In this embodiment, the spiral water injection structure 20 is used to guide external clean water, such as tap water, into the system, so as to mix with the detergent or detergent solution. Specifically, according to the above embodiment, when the cross-sectional shape of the spiral water injection structure 20 is circular, the spiral water injection structure 20 as a whole can be set to an approximately cylindrical shape. A spiral baffle plate 213 that rotates around the axis can be provided inside the spiral water injection structure 20. The spiral baffle plate 213, the bottom plate and the side wall of the spiral water injection structure 20 enclose and form a spiral flow channel 21, so that the water entering the spiral water injection structure 20 can flow along the spiral flow channel 21.

[0061] Based on the above implementation methods, please continue to refer to... Figure 2 The spiral baffle 213 can be set perpendicular to the horizontal plane, thereby causing the spiral flow channel 21 to spiral horizontally. Based on this, as... Figure 4 As shown, the spiral water injection structure 20 is also provided with an inlet 211. The inlet 211 is located on the side of the spiral water injection structure 20 and is connected to the spiral flow channel 21. The inlet 211 can be directly connected to an external water source. The outlet 212 of the spiral flow channel 21 is located at the center of the spiral flow channel 21. Specifically, the outlet 212 is arranged in the vertical direction, and the axis of the outlet 212 coincides with the axis of the spiral water injection structure 20. The water rotating and flowing in the spiral flow channel 21 can flow out in the vertical direction through the outlet 212, and the outlet 212 is connected to the dissolving chamber 22 so that the water flows into the dissolving chamber 22.

[0062] For further information, please refer to [link / reference]. Figure 2 In some embodiments of the present invention, the cross-sectional area of ​​the outermost channel 2101 of the spiral channel 21 is larger than that of the innermost channel 2102. As a result, when water flows in the spiral channel 21, the velocity increases from the outermost channel 2101 to the innermost channel 2102 due to the smaller cross-sectional area, thus further improving the dissolution effect. Furthermore, the spiral channel 21 has multiple channels. In an optional embodiment, the cross-sectional area of ​​each channel decreases sequentially from the outermost channel 2101 to the innermost channel 2102. This allows the water velocity to increase uniformly as the cross-sectional area gradually decreases during flow, further improving the dissolution effect.

[0063] Based on the above implementation methods, please continue to refer to... Figure 2The dissolving chamber 22 is formed at the bottom of the spiral water injection structure 20 and located below the spiral flow channel 21. Understandably, detergent or detergent solution flows from the first outlet 12 of the detergent receiving structure 10 to the dissolving chamber 22, and water flows from the outlet 212 of the spiral water injection structure 20 to the dissolving chamber 22. In this embodiment, the dissolving chamber 22 provides a dissolving space for detergent and water. In some embodiments of the invention, the bottom surface of the spiral flow channel 21 is set as an inclined surface, such as... Figure 2 As shown, the bottom surface of the spiral channel 21 gradually slopes downward from the edge towards the center. That is, the center of the bottom of the spiral channel 21 is its lowest point. Under the influence of gravity, the water in the spiral channel 21 tends to flow towards the center of the bottom, thereby further increasing the water flow velocity. Based on this, the dissolving chamber 22 is located in the central region of the bottom of the spiral water injection structure 20, thus aligning vertically with the outlet 212 of the spiral channel 21. Furthermore, in this embodiment, the bottom plate of the spiral channel 21 and the sidewall of the dissolving chamber 22 are designed with a smooth transition structure, thereby further increasing the flow velocity of the liquid inside.

[0064] For further information, please refer to [link / reference]. Figure 2 According to the above embodiments, the first outlet nozzle 12 extends vertically into the outlet 212 of the spiral flow channel 21 and extends into the dissolving chamber 22. In some embodiments of the present invention, the first outlet nozzle 12 and the outlet 212 are coaxially arranged. When the cross-sectional shape of the dissolving chamber 22 is set to be circular, the first outlet nozzle 12, the outlet 212, and the dissolving chamber 22 are all coaxially arranged. Figure 3 and Figure 4 As shown, the detergent or detergent solution flowing out of the first outlet 12 flows vertically downwards, and the water flowing out of the outlet 212 spirals out from the gap between the outlet 212 and the first outlet 12. Thus, the spirally flowing water comes into contact with the vertically flowing detergent or detergent solution during the outflow process, thereby mixing quickly.

[0065] For further information, please refer to [link / reference]. Figure 2In some embodiments of the present invention, the dissolving chamber 22 is funnel-shaped, thereby forming an acute angle between the sidewall of the dissolving chamber 22 and the vertical direction, which facilitates the flow of liquid inside. Furthermore, the inclined sidewall of the dissolving chamber 22 can block and guide the water flowing from the outlet 212. In this embodiment, the bottom end of the first dispensing nozzle 12 extends into the dissolving chamber 22, and a gap can be formed between the inclined sidewall of the dissolving chamber 22 and the bottom end of the first dispensing nozzle 12. This gap is smaller than the gap between the outlet 212 and the first dispensing nozzle 12, which increases the flow velocity of the water as it passes through, thereby further enhancing the impact force of the water flow and making the dissolution more complete. In addition, when the water and detergent flow to contact the inner wall of the dissolving chamber 22, the funnel-shaped dissolving chamber 22 allows for more complete contact between the detergent and water, thereby further improving the dissolution effect.

[0066] The detergent dissolving device 100 proposed in this embodiment is used in a laundry processing device. After water and detergent are mixed and dissolved, they flow into the tank of the laundry processing device. Please continue reading. Figure 2 In some embodiments of the present invention, the spiral water injection structure 20 further includes a second outlet nozzle 23. The second outlet nozzle 23 is disposed at the bottom of the dissolving chamber 22 and communicates with the dissolving chamber 22. After water and detergent are mixed and dissolved, they flow out through the second outlet nozzle 23. In this embodiment, the second outlet nozzle 23 is used to communicate with the inner tub of the clothing treatment device, so that the detergent solution directly contacts the clothes in the inner tub for washing. Specifically, the shape of the second outlet nozzle 23 can be set as cylindrical. Based on the above embodiments, the second outlet nozzle 23 can be coaxially arranged with the first outlet nozzle 12 and the water outlet 212. The second outlet nozzle 23 can be integrally formed at the bottom of the spiral water injection structure 20.

[0067] Please see Figure 5 and Figure 6 , Figure 5 This is an exploded view of the detergent dispenser 1000 according to an embodiment of the present invention. Figure 6 This is a cross-sectional view of a detergent dispenser 1000 according to an embodiment of the present invention. The second aspect of the present invention provides a detergent dispenser 1000, which includes a lid 300, a body 400, and a detergent dissolving device 100 according to any of the above embodiments. The lid 300 is provided with a lid inlet 301 and a spray nozzle 302 that are connected to each other. The body 400 is connected to the lid 300, and a detergent dispensing chamber 411 is provided inside the body 400, located below the spray nozzle 302. The detergent dissolving device 100 is connected to the body 400 and communicates with the detergent dispensing chamber 411. The receiving cavity 11 of the detergent dissolving device 100 is located downstream of the detergent dispensing chamber 411.

[0068] In the detergent dispenser 1000 of this embodiment, the detergent dispensing chamber 411 is used to dispense detergent. External water can enter the cover 300 through the water inlet 211 and spray out from the spray nozzle 302 to initially dissolve the detergent. The detergent dissolving device 100 is located downstream of the detergent dispensing chamber 411. Therefore, the detergent solution flowing out of the detergent dispensing chamber 411 flows into the receiving chamber 11 of the detergent receiving structure 10 and can flow out from the first liquid outlet 12, thereby contacting and mixing with the water flowing out of the spiral flow channel 21 during the process of flowing into the dissolving chamber 22, realizing a second dissolution. Since the water in the spiral flow channel 21 flows out in a vortex shape, the water impact force is large, thereby improving the mixing intensity of water and detergent solution during the second dissolution process, further improving the dissolution effect. After the water and detergent solution enter the dissolving chamber 22, they are further mixed. In summary, the detergent dispenser 1000 proposed in this embodiment can be applied to clothing processing equipment to improve the dissolution effect of detergent and solve the problem of insufficient detergent dissolution in existing clothing processing equipment.

[0069] For details, please continue reading Figure 5 The detergent dispenser 1000 includes a lid 300 and a body 400. The lid 300 and body 400 can be detachably connected, such as by snap-fit ​​or screw connection, for easy assembly and disassembly. A water inlet 301 can be located on the side of the lid 300 and is connected to an external water source. Furthermore, the body 400 includes a drawer 410, and a detergent dispensing chamber 411 is located within the drawer 410. Users can add detergent to the detergent dispensing chamber 411 by pulling out the drawer 410. Multiple spray nozzles 302 are located on the side of the lid 300 facing the detergent dispensing chamber 411. Clean water flows into the lid 300 from the water inlet 301 and is then sprayed into the detergent dispensing chamber 411 from the multiple spray nozzles 302, initially dissolving the detergent powder or liquid detergent in the chamber.

[0070] Please continue reading. Figure 6 The detergent dissolving device 100 is connected to the box body 400. In some embodiments of the present invention, the box body 400 and the detergent dissolving device 100 are integrally formed, specifically, they can be integrally injection molded for ease of manufacturing. In this embodiment, the receiving cavity 11 of the detergent dissolving device 100 is connected to the detergent dispensing cavity 411, and the receiving cavity 11 is located downstream of the detergent dispensing cavity 411. That is, the detergent solution that has been initially dissolved in the detergent dispensing cavity 411 can flow into the receiving cavity 11 for subsequent second dissolution. In this embodiment, an opening can be provided on one side of the bottom of the detergent dispensing cavity 411, and the opening is located above the receiving cavity 11, so that the detergent solution can flow into the receiving cavity 11 through the opening.

[0071] Based on the above implementation methods, please continue to refer to... Figure 6 The bottom surface of the detergent dispensing chamber 411 is set as an inclined surface, and the bottom surface of the detergent dispensing chamber 411 gradually slopes downward in the direction pointing towards the detergent dissolving device 100. As a result, the detergent solution in the detergent dispensing chamber 411 tends to flow towards a lower position, which facilitates the detergent solution to flow into the receiving chamber 11, further increases the liquid flow rate, and thus speeds up the detergent dispensing efficiency.

[0072] For further information, please refer to [link / reference]. Figure 6 In some embodiments of the present invention, the housing 400 is further provided with an overflow channel 420. In this embodiment, the overflow channel 420 is used to prevent backflow caused by excessive detergent solution, such as... Figure 6 As shown, the overflow channel 420 is connected to the receiving cavity 11 of the detergent dissolving device 100, and the overflow channel 420 is level with the highest water level of the receiving cavity 11. When there is too much detergent solution in the receiving cavity 11, the detergent solution can flow out through the overflow channel 420. When the detergent box 1000 proposed in this embodiment is applied to the clothing processing equipment, the overflow channel 420 is connected to the outer tub of the clothing processing equipment. It can be understood that, based on the second outlet 23 of the detergent dissolving device 100 being connected to the inner tub of the clothing processing equipment, in order to avoid occupying the washing space of the inner tub, the overflow channel 420 is connected to the outer tub in this embodiment, so that the excess detergent solution enters the outer tub and mixes with water, thus preventing the detergent solution from overflowing to the outside.

[0073] An embodiment of the third aspect of the present invention provides a clothing processing device, which includes an inner tub, an outer tub, and a detergent dispenser 1000 according to any of the above embodiments. The detergent dissolving device 100 of the detergent dispenser 1000 is connected to the inner tub. In the embodiments of the present invention, the clothing processing device can be a drum washing machine or a washer-dryer combo.

[0074] The clothing treatment device proposed in this embodiment includes the detergent box 1000. The detergent dispensing chamber 411 of the detergent box 1000 is used to dispense detergent. Water entering the box cover 300 through the water inlet 211 and sprayed out from the spray nozzle 302 can initially dissolve the detergent. The detergent dissolving device 100 located downstream of the detergent dispensing chamber 411 can perform secondary dissolution of the detergent solution. Furthermore, by setting the spiral water injection structure 20, the mixing intensity of water and detergent solution during the secondary dissolution process is improved, further enhancing the dissolution effect. Therefore, the detergent in the clothing treatment device proposed in this embodiment is more fully dissolved, solving the problem of insufficient detergent dissolution in existing clothing treatment devices.

[0075] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
