[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0041] The embodiments of the present application provide a dispensing device and a clothing processing device to solve the problem of low dissolution rate of detergent dispensed into existing washing machines, which will be described below in conjunction with the accompanying drawings.

[0042] The delivery device provided in the embodiment of the present application is applied to a clothing processing device, see Figure 1 and Figure 5 , Figure 1 This is a schematic diagram of the connection between the dispensing device and the washing drum provided in the embodiment of the present application. Figure 5 for Figure 4In the cross-sectional view at AA, the clothes processing device includes a washing tub 6, and the dispensing device includes a detergent box 1 and a liquid extraction assembly 2. The detergent box 1 is provided with a liquid storage tank 111, and the liquid storage tank 111 is used to store detergent; the liquid extraction assembly 2 includes a first tube body 21, a second tube body 22 and an air intake pipe 23, the first tube body 21 is connected with the second tube body 22 and the liquid storage tank 111, so as to extract the detergent in the liquid storage tank 111 into the second tube body 22, one end of the air intake pipe 23 is extended in the liquid storage tank 111, and the other end is connected to the second tube body 22, an air intake channel 231 is provided in the air intake pipe 23, and the height of the air intake pipe 23 in the liquid storage tank 111 is higher than the liquid level of the detergent, and the second tube body 22 is connected with the washing tub 6.

[0043] The dispensing device provided in the embodiment of the present application sequentially pumps the detergent in the liquid storage tank 111 of the detergent box 1 into the washing tub 6 through the first tube body 21 and the second tube body 22, and at the same time, air is introduced into the second tube body 22 through the air intake pipe 23 to improve the stirring and emulsifying ability of the detergent, reduce the surface tension of the detergent, and thus improve the foaming effect of the detergent during the flow process and the dissolution rate of the detergent. At the same time, since the end of the air intake pipe 23 away from the second tube body 22 is extended into the liquid storage tank 111 of the detergent box 1, dust is not easily accumulated in the air intake pipe 23 under the cover of the detergent box 1, thereby ensuring the cleanliness of the dispensing device.

[0044] Optionally, one end of the air inlet pipe 23 is inserted into the first tube body 21 , and a liquid inlet channel 211 is formed between the air inlet pipe 23 and the first tube body 21 . The liquid inlet channel 211 communicates with the second tube body 22 and the liquid storage tank 111 .

[0045] Since the air inlet pipe 23 is plugged into the first tube body 21, the liquid storage tank 111 only needs to be provided with one opening to communicate with the first tube body 21, and there is no need to provide two openings to respectively connect the first tube body 21 and the air inlet pipe 23, thereby simplifying the structure of the detergent box 1 and saving production processes. At the same time, the air inlet pipe 23 is plugged into the first tube body 21, that is, the air inlet pipe 23 can be separately provided from the first tube body 21, so the tube type of the air inlet pipe 23 and the tube type of the first tube body 21 can be selected from the existing tube types and directly plugged in, and there is no need to separately make a mold for the air inlet pipe 23 and the first tube body 21 that are integrally connected, thereby saving production costs. Moreover, the air inlet pipe 23 is entirely located in the detergent box 1, making the overall dispensing device more harmonious and beautiful.

[0046] As an alternative embodiment, the air inlet pipe 23 may also be formed integrally with the first tube body 21 , thereby simplifying the installation process of the liquid extraction assembly 2 and the detergent box 1 .

[0047] Optionally, the flow area of ​​the liquid inlet channel 211 gradually decreases along the flow direction of the liquid, thereby increasing the adsorption force of the liquid inlet channel 211, increasing the liquid absorption capacity of the first tube body 21, and improving the liquid delivery speed of the first tube body 21.

[0048] The shape of the liquid inlet channel 211 is not further limited here. In some examples, the first tube body 21 is cylindrical, and the inner diameter of the first tube body 21 gradually decreases towards the end close to the second tube body 22, and the air intake pipe 23 includes a connected arcuate tube wall and a vertical tube wall, and the arcuate tube wall is in contact with part of the side wall of the first tube body 21; in some examples, the first tube body 21 is cylindrical and the inner diameter of the first tube body 21 remains unchanged along the extension direction, and the outer diameter of the part of the air intake pipe 23 inserted in the first tube body 21 gradually increases towards the end close to the second tube body 22, wherein the air intake pipe 23 may be protrudingly provided with connecting ribs, so that the air intake pipe 23 is connected and fixed to the first tube body 21 through the connecting ribs.

[0049] Optionally, the detergent box 1 includes a base 11, the base 11 is provided with a liquid storage tank 111, the bottom of the liquid storage tank 111 is provided with a first liquid outlet, the first tube body 21 connects the first liquid outlet and the second tube body 22, and the end of the air inlet pipe 23 away from the first tube body 21 is higher than the slot of the liquid storage tank 111.

[0050] That is, the first tube body 21 is connected to the bottom of the liquid storage tank 111, ensuring that the first tube body 21 can absorb the detergent in the liquid storage tank 111 to the maximum extent, and avoiding that the tube mouth of the first tube body 21 is higher than the bottom of the liquid storage tank 111, resulting in the detergent at the bottom of the liquid storage tank 111 not being absorbed and being deposited to breed bacteria. At the same time, the end of the air intake pipe 23 away from the first tube body 21 is higher than the slot of the liquid storage tank 111, thereby ensuring that even if the liquid storage tank 111 is full of detergent, no detergent will enter the air intake pipe 23, preventing the detergent from clogging the air intake pipe 23 and affecting the air intake effect of the air intake pipe 23.

[0051] Optionally, the air inlet pipe 23 is inserted through the first tube body 21 , thereby ensuring that the flow area of ​​the liquid inlet channel 211 gradually decreases along the flow direction of the liquid in the first tube body 21 , further improving the liquid inlet speed of the liquid inlet channel 211 .

[0052] Optionally, the outer wall of the base 11 includes a surrounding plate 113 arranged around the first liquid outlet, and the first tube body 21 is provided with a connecting plate 212 protruding along the circumferential direction, and the connecting plate 212 is sealed and connected to the surrounding plate 113 through a sealing ring 3. The connecting plate 212 is sealed and connected to the surrounding plate 113 to avoid leakage at the connection between the first tube body 21 and the first liquid outlet.

[0053] The distance between the enclosure 113 and the first liquid outlet is not further limited here, nor is the sealing position of the sealing ring 3. In some examples, the sealing ring 3 can be clamped between the connecting plate 212 and the enclosure 113; in other examples, the sealing ring 3 can be clamped between the connecting plate 212 and the base 11.

[0054] Optionally, the detergent box 1 is further provided with a water inlet and a solid storage chamber 121 in communication, the solid storage chamber 121 is provided with a second liquid outlet 123, and the second liquid outlet 123 is in communication with the liquid storage tank 111; Figure 6 , Figure 7 and Figure 8 , Figure 6 An exploded view of the liquid extraction component of the delivery device provided in an embodiment of the present application, Figure 7 This is a schematic diagram of the structure of the liquid extraction component of the delivery device provided in an embodiment of the present application. Figure 8 This is a front view of the liquid extraction component of the dispensing device provided in the embodiment of the present application. The liquid extraction component 2 also includes a protective cover 24, which is arranged at one end of the air inlet pipe 23 away from the first tube body 21. The side of the protective cover 24 away from the second liquid outlet 123 is provided with an air inlet 241, and the air inlet 241 is connected to the air inlet channel 231. Among them, the solid storage chamber 121 is used to store solid detergents, such as washing powder, bleaching powder, etc.

[0055] The water inlet feeds liquid into the solid storage cavity 121 to dissolve the solid detergent in the solid storage cavity 121 and form a washing solution, and the washing solution flows to the liquid storage tank 111 through the second liquid outlet 123. A protective cover 24 is provided to cover the top of the air inlet pipe 23 to prevent the incompletely dissolved solid detergent from flying to the air inlet pipe 23 with the washing solution, thereby blocking the air inlet pipe 23. At the same time, an air inlet 241 connected to the air inlet channel 231 is provided on the protective cover 24, and the air inlet 241 is arranged on the side of the protective cover 24 away from the second liquid outlet 123, thereby ensuring the air intake effect of the air inlet pipe 23 and preventing the air inlet pipe 23 from being blocked.

[0056] The shape of the air inlet 241 is not further limited here. In some examples, the air inlet 241 may be a round hole, a bar-shaped hole, or the like.

[0057] Optionally, the air intake pipe 23 is provided with a mounting platform 232 protruding along the circumferential direction, the protective cover 24 is provided on the outer circumference of the air intake pipe 23 and installed on the mounting platform 232, an air intake gap is provided between the end of the air intake pipe 23 away from the first tube body 21 and the protective cover 24, and the air intake port 241 is connected with the air intake channel 231 through the air intake gap.

[0058] By protruding a mounting platform 232 on the outer periphery of the air intake pipe 23 , a bearing structure is provided for the protection cover 24 , thereby improving the stability of the connection between the protection cover 24 and the air intake pipe 23 .

[0059] As a specific implementation, the protective cover 24 is plugged into the air intake pipe 23 ; as another specific implementation, the protective cover 24 is disposed on the outer periphery of the air intake pipe 23 , and a gap is reserved between the protective cover 24 and the pipe wall of the air intake pipe 23 .

[0060] Optionally, see Figure 3 , Figure 3 The schematic diagram of the connection between the base and the dispensing pump of the dispensing device provided in the embodiment of the present application, the dispensing device provided in the embodiment of the present application further comprises a dispensing pump 4, the dispensing pump 4 comprises a liquid extraction end 41 and a liquid outlet end 42, a liquid storage chamber 122 is further provided in the detergent box 1, the liquid extraction end 41 is connected to the liquid storage chamber 122, and the liquid outlet end 42 is connected to the liquid storage tank 111. The liquid storage chamber 122 is used to store liquid detergents, such as laundry detergent, bleaching liquid, softening liquid, care liquid, etc.

[0061] By setting up the delivery pump 4, the liquid detergent in the liquid storage chamber 122 can be automatically extracted and delivered, and the delivery amount is relatively accurate, so as to avoid excessive or insufficient detergent, which affects the washing effect. Among them, the liquid extraction end 41 of the delivery pump 4 extracts the liquid detergent in the liquid storage chamber 122 and delivers it to the liquid storage tank 111 through the liquid outlet end 42, that is, the liquid storage tank 111 is only used to temporarily store the detergent required for the delivery. Different from the liquid storage chamber 122, the liquid storage chamber 122 can store more liquid detergent for a long time. Each time washing, the delivery pump 4 can be used to extract a preset volume of detergent, that is, the user does not need to manually add liquid detergent every time washing, and can only add it when the detergent stock in the liquid storage chamber 122 is insufficient.

[0062] Optionally, see Figure 2 and Figure 4 , Figure 2 An exploded view of the delivery device provided in an embodiment of the present application, Figure 4 This is a top view of the detergent box of the dispensing device provided in an embodiment of the present application. The detergent box 1 also includes a first box body 12 and a second box body 13. The first box body 12 is slidably arranged in the base 11 and has a gap between the base 11. The second box body 13 is located above the first box body 12 and is fixedly connected to the base 11. A water inlet is provided on the second box body 13. A solid storage cavity 121 and a liquid storage cavity 122 are provided in the first box body 12. The water inlet is connected to the solid storage cavity 121, and the liquid storage cavity 122 is located above the liquid storage tank 111.

[0063] Optionally, the base 11 is further provided with a third liquid outlet 112, the third liquid outlet 112 is spaced apart from the liquid storage tank 111, the solid storage chamber 121 is located above the third liquid outlet 112, the base 11 further includes a guide surface surrounding the third liquid outlet 112, the orthographic projection of the second liquid outlet 123 on the base 11 falls on the guide surface, and the guide surface is used to guide the washing solution flowing out of the second liquid outlet 123 to the third liquid outlet 112. Since there is a gap between the first box body 12 and the base 11, the washing solution or solid detergent flowing out of the second liquid outlet 123 still has the risk of splashing to the air inlet pipe 23, so the protective cover 24 protects the air inlet pipe 23 to prevent the solid detergent from blocking the air inlet channel 231.

[0064] Furthermore, the first box body 12 may be provided with a plurality of solid storage chambers 121 or liquid storage chambers 122, each storage chamber storing a type of detergent, which will not be further described herein.

[0065] Optionally, see Figure 6 , Figure 7 and Figure 8 , Figure 6 An exploded view of the liquid extraction component of the delivery device provided in an embodiment of the present application, Figure 7 This is a schematic diagram of the structure of the liquid extraction component of the delivery device provided in an embodiment of the present application. Figure 8 The front view of the liquid extraction component of the dispensing device provided in the embodiment of the present application, the second tube body 22 includes a first tube segment 221, a second tube segment 222 and a third tube segment 223 which are connected in sequence, the inner diameter of the second tube segment 222 is smaller than the first tube segment 221 and the third tube segment 223, the second tube segment 222 is provided with a connecting port, the connecting port is connected to the first tube body 21, and the third tube segment 223 is connected to the washing drum 6; the dispensing device also includes a water inlet valve 5, the water inlet valve 5 is connected to the first tube segment 221, the water inlet valve 5 supplies liquid to the first tube segment 221, so that a negative pressure is formed at the connecting port to absorb the liquid in the first tube body 21.

[0066] In some examples, the first tube body 21 and the second tube body 22 are an integrally formed venturi tube, which utilizes the negative pressure suction principle of the venturi tube to realize automatic extraction and delivery of detergent in the liquid storage tank 111, without the need for an additional power source to realize liquid extraction, and only water needs to be introduced into the first tube section 221 of the venturi tube.

[0067] Optionally, the dispensing device provided in the embodiment of the present application further includes a liquid inlet pipe, which connects the third tube body and the washing tub 6 , and an end of the liquid inlet pipe away from the third tube body is arranged toward the tube mouth of the washing tub 6 .

[0068] In the dispensing device provided in the embodiment of the present application, the air inlet channel 231 and the liquid inlet channel 211 are both connected to the connecting port of the second pipe section 222. Therefore, when the water inlet valve 5 lets water into the first pipe section 221, a negative pressure is formed at the connecting port, which will accelerate the air intake speed of the air inlet channel 231 and the liquid intake speed of the liquid inlet channel 211, further improving the foaming effect of the detergent.
