DETAILED DESCRIPTION

[0032] Embodiments of the present application are described below in detail with reference to the accompanying drawings, in which the same or similar elements or elements having the same or similar functions are denoted by the same or similar reference numerals throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are intended only for explanation of the present application, and cannot be understood as limiting the present application.

[0033] A dispensing assembly 1 for a laundry treating apparatus according to embodiments of the present application is described below with reference to FIGS. 1-13.

[0034] The dispensing assembly 1 for a laundry treating apparatus according to the present application is adapted to be mounted on a worktop of a laundry treating apparatus, and comprises a housing 11, a first waterway 13 and a second waterway 12, the housing 11 having a water inlet end 111 connected to a water source and a liquid outlet end 112 for discharging fluid, the first waterway 13 communicating the water inlet end 111 and the liquid outlet end 112, and the second waterway 12 communicating the water inlet end 111 and the liquid outlet end 112, the second waterway 12 being provided with a foam generating device 120.

[0035] The dispensing assembly 1 for the laundry treatment equipment according to the present application is provided with a housing 11, which is a basic support structure of the dispensing assembly 1 for the laundry treatment equipment, and can be matched with a workbench of the laundry treatment equipment to facilitate the installation of the dispensing assembly 1 for the laundry treatment equipment, and the inside of the housing 11 can be provided with various structural parts of the dispensing assembly 1 for the laundry treatment equipment. In some embodiments, the housing 11 is provided with a water inlet end 111 for connecting a water source and a liquid outlet end 112 for discharging the mixed liquid. At least two flow paths suitable for water or mixed liquid are provided in the housing 11, such as a first water path 13 and a second water path 12, which are respectively communicated with the water inlet end 111 and the liquid outlet end 112 of the housing 11. The second water path 12 is further provided with a foam generating device 120 for generating foam. When the washing material is added to the dispensing assembly 1 for the laundry treatment equipment, part of the washing material can directly enter the first water path 13 and flow with the water in the first water path 13, and the water and the washing material in the first water path 13 can be mixed and then discharged through the outlet of the first water path 13 and finally through the liquid outlet end 112; the other part of the washing material can enter the foam generating device 120 in the second water path 12, and the water entering the dispensing assembly 1 for the laundry treatment equipment through the water inlet end 111 can be fully mixed with the washing material in the foam generating device 120, and the mixed liquid can be foamed under the action of the foam generating device 120, and then discharged through the outlet of the second water path 12 and the liquid outlet end 112. The first water path 13 and the second water path 12 can discharge the mixed liquid respectively or simultaneously, and the setting of the foam generating device 120 in the second water path 12 increases the foam in the mixed liquid. The foam has a larger surface structure than the liquid, and can better clean the laundry when in contact with the laundry, effectively improving the washing effect of the laundry treatment equipment.

[0036] The dispensing assembly 1 for the laundry treatment equipment according to the present application can select the water path according to different washing requirements, has more choices under the premise of meeting the washing requirements, improves the diversity of the dispensing assembly 1, and due to the setting of the foam generating device 120 in the second water path 12, the design of the second water path 12 can reduce the cost of the washing material to a certain extent, improve the use rate of the washing material, and further improve the washing effect of the laundry treatment equipment.

[0037] The dispensing assembly 1 for the laundry treatment equipment is installed on the workbench, and compared with other positions of the laundry treatment equipment, the operation of the laundry treatment equipment by the user and a series of procedures such as adding washing material can be concentrated in the workbench area, which is convenient for the user to operate, and also facilitates the maintenance and disassembly of the dispensing assembly 1 for the laundry treatment equipment.

[0038] The first waterway 13 and the second waterway 12 can be designed to have two different mixed liquid flow routes for the dispensing assembly 1 of the laundry treatment apparatus, and the two waterways can be used separately or simultaneously. The two waterways correspond to different detergent dispensing modes and applicable washing requirements, and thus, in actual situations, different waterways can be selected to be conducted or both waterways can be simultaneously conducted according to different washing requirements, which can provide more choices under the premise of meeting washing requirements and improve the diversity of the dispensing assembly 1 of the laundry treatment apparatus. The foam generating device 120 arranged in the second waterway 12 can make the mixed liquid generate more foam and improve the use rate of the washing material. In the use of the same amount of washing material, the mixed liquid generating more foam has better cleaning effect, and thus, the design of the second waterway 12 can reduce the use cost of the washing material to a certain extent.

[0039] In some embodiments, the laundry treatment apparatus can be a drum washing machine, a laundry treatment apparatus, or the like model of washing apparatus, and the dispensing assembly 1 of the present application is particularly suitable for a vertical shaft rotating impeller washing machine.

[0040] In some embodiments, the washing material can be a detergent, a softener, a sterilizing agent, or other functional agents for cleaning.

[0041] According to some embodiments of the present application, the housing 11 is formed with a dispensing cavity 113, the inner wall of the dispensing cavity 113 is formed with a first outlet 1131 communicating with the liquid outlet 112 and an inlet communicating with the first waterway 13, and the first waterway 13 communicates with the liquid outlet 112 through the dispensing cavity 113.

[0042] In processing, the shell 11 can be processed into a delivery cavity 113, which is a cavity for accommodating washing substances. The inner wall of the delivery cavity 113 can be provided with a first outlet 1131 communicating with the liquid outlet end 112 and an inlet communicating with the water inlet end 111. It can also be understood that the water in the first waterway 13 will flow through the delivery cavity 113. In actual use, the user can directly put the washing substances into the delivery cavity 113. At least part of the washing substances in the delivery cavity 113 can be mixed with the water flow in the first waterway 13 and flow out through the liquid outlet end 112 for cleaning clothes. The setting of the delivery cavity 113 facilitates the user to put the washing substances, optimizes the process of the user to put the washing substances, reduces the difficulty of putting, and improves the user experience. The delivery cavity 113 can be understood as a storage space for washing substances in the delivery assembly 1 for the clothes treatment equipment. For example, for liquid washing substances, they can be directly poured into the delivery cavity 113, and then mixed with the water flow in the first waterway 13 and flow out through the first outlet 1131. For solid washing substances, the water flow in the first waterway 13 can fully dissolve and mix with the solid washing substances in the delivery cavity 113, and the mixed liquid can flow out through the first waterway 13. This design can ensure that the washing substances can be fully mixed with the water in the first waterway 13, and can improve the washing effect of the delivery assembly 1 for the clothes treatment equipment.

[0043] In addition, since the washing substances only need to be put into the delivery cavity 113 when the washing substances are delivered, the washing substances will not contaminate other structures of the delivery assembly 1 for the clothes treatment equipment, avoiding the residues of the washing substances between the structures inside the delivery assembly 1 for the clothes treatment equipment, and avoiding the secondary pollution of the delivery assembly 1 for the clothes treatment equipment in use.

[0044] According to some embodiments of the present application, the first waterway 13 comprises a first flow channel section, one end of the first flow channel section is in communication with the water inlet end 111, and the other end of the first flow channel section is in communication with the delivery cavity 113 through an inlet provided on the side wall of the delivery cavity 113. The first waterway 13 is in communication with the liquid outlet end 112 through the delivery cavity 113, which can be simply understood as that the delivery cavity 113 divides the first waterway 13 into two sections, and the first waterway 13 between the delivery cavity 113 and the water inlet end 111 can be understood as the first flow channel section, which can be in communication with the inlet on the delivery cavity 113. It should be noted that the inlet of the delivery cavity 113 can be provided on the side wall of the delivery cavity 113. When the user puts the washing material into the delivery cavity 113, the water inlet end 111 is supplied with water, and part of the water flow flows into the delivery cavity 113 through the first flow channel section. At this time, since the inlet of the delivery cavity 113 is located on the side wall of the delivery cavity 113, the water flow of the first flow channel section can impact the delivery cavity 113 from the side wall of the delivery cavity 113 so as to fully mix the water flow and the washing material, and at the same time, the washing material remaining on the side wall of the delivery cavity 113 can be washed away, reducing the residue of the washing material in the delivery cavity 113.

[0045] In some embodiments, the delivery cavity 113 can be divided into a first sub-cavity 1132 and a second sub-cavity 1133 by a partition structure, and at this time, the first flow channel section can be correspondingly divided into a first sub-waterway 131 and a second sub-waterway 132. As shown in FIG. 5, the first sub-waterway 131 and the second sub-waterway 132 are respectively arranged around the first sub-cavity 1132 and the second sub-cavity 1133, a first inlet 1311 is provided in the first sub-cavity 1132, and a second inlet 1321 is provided in the second sub-cavity 1133. The first sub-waterway 131 and the second sub-waterway 132 are respectively in communication with the first inlet 1311 and the second inlet 1321. A flow guide plate 133 extending towards the first sub-cavity 1132 can be provided on the first inlet 1311, which can guide the water flow in the first waterway 13 towards the first sub-cavity 1132 so as to fully clean at least part of the side wall of the first sub-cavity 1132. Similarly, the second inlet 1321 can also be provided with a flow guide plate 133, and the number of the first inlet 1311 and the second inlet 1321 can be increased or decreased according to actual conditions. Multiple first inlets 1311 and multiple second inlets 1321 can flush the side wall of the corresponding sub-cavity from more angles.

[0046] According to some embodiments of the present application, the first waterway 13 further comprises a second flow channel section, one end of the second flow channel section being in communication with the first outlet 1131, and the other end of the second flow channel section being in communication with the liquid outlet end 112. Corresponding to the first flow channel section, the first waterway 13 further comprises a second flow channel section, the second flow channel section being in communication with the delivery cavity 113 and the liquid outlet end 112. It can also be understood that the inlet of the second flow channel section is in communication with the first outlet 1131 in the delivery cavity 113, and the water flowing into the first waterway 13 from the water inlet end 111 flows to the second flow channel section through the first outlet 1131 after mixing with the washing material in the delivery cavity 113 and finally flows out through the liquid outlet end 112. As shown in FIG. 5, the first outlet 1131 corresponding to the first sub-cavity 1132 and the first outlet 1131 corresponding to the second sub-cavity 1133 can be the same, i.e., the first outlet 1131 spans at least part of the first sub-cavity 1132 and at least part of the second sub-cavity 1133. The first outlet 1131 does not need to be arranged in each sub-cavity, which can reduce the processing difficulty.

[0047] According to some embodiments of the present application, the foam generating device 120 comprises a main flow path 1200 and a liquid inlet flow path 124, the main flow path 1200 being arranged in the second waterway 12 and between the water inlet end 111 and the liquid outlet end 112, and the main flow path 1200 being provided with a liquid inlet 121; one end of the liquid inlet flow path 124 is in communication with the liquid inlet 121, and the other end of the liquid inlet flow path 124 is in communication with the delivery cavity 113 on the shell 11, and the liquid inlet flow path 124 is used to communicate the delivery cavity 113 with the main flow path 1200.

[0048] The foam generating device 120 is provided with a main flow path 1200 and a liquid inlet flow path 124. The main flow path 1200 is a main body part of the foam generating device 120, and the main flow path 1200 is in communication with the water inlet end 111 and the liquid outlet end 112. Part of the water flow entering the water inlet end 111 can flow through the main flow path 1200 and then flow out through the liquid outlet end 112. The liquid inlet flow path 124 is in communication with the main flow path 1200 and the dispensing cavity 113. In some embodiments, the main flow path 1200 is provided with a liquid inlet 121, which can be in communication with the dispensing cavity 113 to realize the communication between the dispensing cavity 113 and the main flow path 1200. After the washing material is put into the dispensing cavity 113, part of the washing material can flow into the main flow path 1200 through the liquid inlet 121 of the liquid inlet flow path 124. The washing material flowing into the main flow path 1200 and the water flowing into the main flow path 1200 through the water inlet end 111 can be mixed and then generate a large amount of foam under the action of the foam generating device 120. The mixed liquid mixed with the foam can flow out through the liquid outlet end 112 and then be used for cleaning the to-be-washed object. The arrangement of the liquid inlet flow path 124 and the main flow path 1200 can distinguish the routes of the clean water and the washing material in the second flow path. The washing material in the dispensing cavity 113 can be introduced into the foam generating device 120 through the liquid inlet flow path 124, which can reduce the operation difficulty of directly putting the washing material into the foam generating device 120. The user only needs to put the washing material into the dispensing cavity 113 to complete the dispensing of the washing material in the first water path 13 and the second water path 12, which is simple and convenient.

[0049] According to some embodiments of the present application, the foam generating device 120 further comprises an air suction channel 123 penetrating through the wall of the shell 11. One end of the air suction channel 123 is in communication with the air suction port 122 of the main flow path 1200, and the other end is in communication with the outside of the shell 11. In some embodiments, the main flow path 1200 is formed with the air suction port 122, and the foam generating device 120 can further be provided with the air suction channel 123 for connecting the air suction port 122 with the outside. When the foam generating device 120 is used, the washing material and the water flow enter the main flow path 1200 through the liquid inlet flow path 124 and the inlet of the main flow path 1200 respectively and are mixed in the main flow path 1200. At this time, the external air can enter the main flow path 1200 through the air suction channel 123. When the washing material and the water flow are foamed in the foam generating device 120, the amount of foam can be increased due to the intervention of the air, so that the foam generating device 120 generates more foam, thereby improving the cleaning effect of the second water path 12. In addition, the air entering the main flow path 1200 can also remain in the foam, which can improve the stability of the foam, increase the time of foam retention, and improve the washing effect.

[0050] According to some embodiments of the present application, the air inlet 122 and the liquid inlet 121 are at least partially opposite in the radial direction of the main flow path 1200. During processing, the air inlet 122 and the liquid inlet 121 can be at least partially opposite, and since the air inlet 122 and the liquid inlet 121 are at least partially opposite in the radial direction of the main flow path 1200, external air can directly enter the main flow path 1200 through the air inlet 122 while the washing material flows through the liquid inlet hole into the main flow path 1200, ensuring that air and mixed liquid are fully contacted and mixed in the main flow path 1200, thereby generating more stable foam.

[0051] According to some embodiments of the present application, the main flow path 1200 includes a first section 1201 and a second section 1202, one end of the first section 1201 is in communication with the water inlet end 111; one end of the second section 1202 is in communication with the other end of the first section 1201, and the second section 1202 is provided with the air inlet 122 and the liquid inlet 121; wherein the diameter of the second section 1202 is smaller than the diameter of the first section 1201.

[0052] In some embodiments, the main flow path 1200 is provided with the first section 1201 and the second section 1202 connected in sequence, wherein the first section 1201 is in communication with the water inlet end 111; the second section 1202 is in communication with the liquid outlet end 112, and the water inlet end 111 enters a part of the water which can flow through the first section 1201 and the second section 1202 in sequence and then flow out through the liquid outlet end 112, in this process, the washing material in the throwing cavity 113 can enter the second section 1202 through the liquid inlet 121 on the second section 1202, at the same time, external air can enter the second section 1202 through the air inlet 122, and the washing material, air and water are mixed in the main flow path 1200. The diameter of the second section 1202 is smaller than the diameter of the first section 1201 and the diameter of the third section 1203, so that the flow rate in the second section 1202 is large, a low pressure area relative to the first section 1201 can be formed in the second section 1202, which can improve the rate of air entering the second section 1202 and increase the mixing effect of gas and liquid, at this time, the mixed liquid can be mixed in the second section 1202 to generate a large amount of foam, and the mixed liquid mixed with the foam flows out through the liquid outlet end 112 after flowing out through the outlet of the second section 1202 for cleaning the to-be-washed material, and the cleaning effect is better.

[0053] According to some embodiments of the present application, the main flow path 1200 further comprises a third section 1203, one end of the third section 1203 is in communication with the other end of the second section 1202, and the other end of the third section 1203 is in communication with the liquid outlet end 112; and the diameter of the third section 1203 is greater than the diameter of the second section 1202. In some embodiments, the main flow path 1200 can further be provided with a third section 1203, which can be arranged between the second section 1202 and the liquid outlet end 112 and in communication with the second section 1202 and the liquid outlet end 112. The mixed liquid mixed with the foam flows out of the outlet of the second section 1202 and enters the third section 1203. The diameter of the third section 1203 is greater than the diameter of the second section 1202, so the flow rate of the mixed liquid in the third section 1203 is slower than that in the second section 1202. At this time, the foam mixed liquid flows more smoothly in the third section 1203, which can reduce the risk of foam rupture and ensure that the foam can act on the to-be-washed objects perfectly, thereby improving the cleaning effect of the dispensing assembly 1 for the laundry treatment apparatus.

[0054] According to some embodiments of the present application, the second water path 12 comprises a third flow passage section and a fourth flow passage section. One end of the third flow passage section is in communication with the water inlet end 111, and the other end of the third flow passage section is in communication with one end of the first section 1201. One end of the fourth flow passage section is in communication with the other end of the third section 1203, and the other end of the fourth flow passage section is in communication with the liquid outlet end 112.

[0055] The second water path 12 flows through the foam generating device 120, so it can be simply understood that the foam generating device 120 divides the second water path 12 into the third flow passage section and the fourth flow passage section. The third flow passage section communicates the water inlet end 111 with the foam generating device 120, and the fourth flow passage section communicates the foam generating device 120 with the liquid outlet end 112. The arrangement of the third flow passage section and the fourth flow passage section makes the path of the second water path 12 clearer, and the flow path of the second flow passage can also be adaptively adjusted according to the specific structure of the dispensing assembly 1 for the laundry treatment apparatus, which can more accurately control the flow of the mixed liquid.

[0056] According to some embodiments of the present application, the bottom of the dispensing cavity 113 is provided with a second outlet 1136, which is in communication with the liquid inlet 121 to define a liquid inlet flow path 124. The second outlet 1136 is a structure for realizing the communication between the liquid inlet flow path 124 and the dispensing cavity 113. In some embodiments, the first outlet 1131 needs to be higher than the bottom of the dispensing cavity 113 to avoid the washing material flowing out directly through the first outlet 1131 when the washing material is dispensed. The second outlet 1136 needs to be arranged at the bottom of the dispensing cavity 113, so that the washing material flows out of the dispensing cavity 113 and into the main flow path 1200 by the action of gravity, which improves the rate of the washing material entering the main flow path 1200 and reduces the residue of the washing material in the dispensing cavity 113.

[0057] According to some embodiments of the present application, the dispensing assembly 1 for the clothes treatment apparatus further comprises a switching device selectively connecting at least one of the first water path 13 and the second water path 12 to the water inlet end 111. The switching device can be arranged at the position of the water inlet end 111 and upstream of the inlet of the first water path 13 and the inlet of the second water path 12, i.e. the switching device can control the connection or the closing between the first water path 13 and the second water path 12 and the water inlet end 111, for example, the switching device can control the connection of the first water path 13 and the water inlet end 111 and the closing of the second water path 12; or the switching device can also control the closing of the first water path 13 and the connection of the second water path 12; or the switching device can also control the connection of the first water path 13 and the second water path 12 and the water inlet end 111 at the same time, and the specific control condition can be determined according to actual needs. The arrangement of the switching device makes the dispensing assembly 1 for the clothes treatment apparatus can flexibly select the first water path 13 and the second water path 12 according to needs, so that the dispensing assembly 1 for the clothes treatment apparatus has more controllability and flexibility.

[0058] According to some embodiments of the present application, the switching device is configured as an on-off valve, which is arranged in the first water path 13 and can selectively connect or close the first water path 13, and / or which is arranged in the second water path 12 and can selectively connect or close the second water path 12.

[0059] The configuration of the switching device will affect the control of the dispensing assembly 1 for the clothes treatment apparatus on the first water path 13 and the second water path 12, for example, the switching device can be configured as an on-off valve, and the on-off valve can be configured as two corresponding to the first water path 13 and the second water path 12, and respectively control the connection or the closing of the first water path 13 and the connection or the closing of the second water path 12. In some embodiments, an on-off valve can be arranged between the first water path 13 and the water inlet end 111, and similarly, an on-off valve can also be arranged between the second water path 12 and the water inlet end 111. The arrangement of the two on-off valves makes the control of the connection and the closing state of the first water path 13 and the second water path 12 independent, and the corresponding water path can be selected for use according to needs, and the state of the two water paths will not affect each other.

[0060] According to some embodiments of the present application, the switching device is configured as a reversing valve 14, which is provided with a first valve port 141, a second valve port 142 and a third valve port 143. The first valve port 141 is in communication with the water inlet end 111, the second valve port 142 is in communication with the inlet of the first water path 13, and the third valve port 143 is in communication with the inlet of the second water path 12. The reversing valve 14 can selectively connect the first valve port 141 with the second valve port 142 or connect the first valve port 141 with the third valve port 143.

[0061] Different from the on-off valve in the above embodiments, the switching device can also be configured as a reversing valve 14, as shown in FIGS. 4, 5 and 6, which has three valve ports, i.e., a first valve port 141, a second valve port 142 and a third valve port 143. The first valve port 141 is an inlet of the reversing valve 14 and is in communication with the water inlet end 111. The second valve port 142 is an outlet of the reversing valve 14 and is in communication with the first water path 13. The third valve port 143 is also an outlet of the reversing valve 14 and is in communication with the inlet of the second water path 12. The reversing valve 14 can control the conduction between the first valve port 141 and the second valve port 142 or the conduction between the first valve port 141 and the third valve port 143 according to the cleaning requirement, and the operation of the reversing valve 14 is more convenient when a single water path is selected.

[0062] In some embodiments, when the switching device adopts the structure of the reversing valve 14, as shown in FIG. 9, the housing 11 can be provided with a first cavity 1141, a second cavity 1142 and a third cavity 1143 corresponding to the communication areas of the first valve port 141, the second valve port 142 and the third valve port 143, respectively. The first valve port 141 is in communication with the water inlet end 111 through the first cavity 1141, the second valve port 142 is in communication with the first water path 13 through the second cavity 1142, and the third valve port 143 is in communication with the second water path 12 through the third cavity 1143. The provision of the three cavities can adapt the water paths of the first water path 13, the second water path 12 and the water inlet end 111 of the dispensing assembly 1 for the laundry treating apparatus in the thickness direction of the dispensing assembly 1 for the laundry treating apparatus, so as to adjust the layout of the internal structure of the dispensing assembly 1 for the laundry treating apparatus. For example, when the second water path 12 is located at the bottom of the dispensing cavity 113, the third cavity 1143 extends in the thickness direction of the dispensing assembly 1 for the laundry treating apparatus, and the water flowing out of the reversing valve 14 can be guided into the second water path 12 at the bottom of the dispensing assembly 1 for the laundry treating apparatus, so as to improve the compactness of the dispensing assembly 1 for the laundry treating apparatus.

[0063] According to some embodiments of the present application, the dispensing assembly 1 for the laundry treating apparatus further comprises a foam dispensing device 16, which is arranged in the housing 11 and communicates the outlet of the second water path 12 with the liquid outlet end 112 to foam the mixed liquid flowing out of the second water path 12.

[0064] The foam delivery device 16 can be arranged between the foam generating device 120 and the water outlet end, and can be used to increase the foam content of the mixed liquid flowing out of the foam generating device 120. Due to the size limitation of the foam generating device 120, the flow time of the mixed liquid in the foam generating device 120 is relatively short. Therefore, the arrangement of the foam delivery device 16 can re-foam the mixed liquid flowing out of the foam generating device 120, increase the foam content, and improve the cleaning effect of the delivery assembly 1 of the laundry treatment apparatus.

[0065] According to some embodiments of the present application, the foam delivery device 16 comprises a barrel 164 and a spiral blade 165. At least one end of the barrel 164 is respectively provided with a foam outlet communicating with the liquid outlet end 112. At least one end or between two ends of the barrel 164 is provided with a foam inlet 163 communicating with the outlet of the second waterway 12. The spiral blade 165 is fixedly arranged in the barrel 164.

[0066] As shown in FIG. 4, the foam delivery device 16 is provided with a barrel 164 and a spiral blade 165. The barrel 164 forms a cavity accommodating the spiral blade 165. The spiral blade 165 is fixedly arranged in the cavity of the barrel 164. The spiral blade 165 can be used to cut the water flow. The foam delivery device 16 can be communicated with the outlet of the second waterway 12 through the foam inlet 163 between the two ends (e.g. the middle position) of the barrel 164. The mixed liquid flowing out of the foam generating device 120 can enter the barrel 164 through the foam inlet 163, and more foam can be generated under the action of the spiral blade 165. The mixed liquid mixed with more foam can flow to the liquid outlet end 112 through the first foam outlet 161 and the second foam outlet 162 at the two ends of the barrel 164.

[0067] In some embodiments, a rotatable spiral impeller can be arranged in the barrel 164. The spiral impeller can be used to stir the mixed liquid in the barrel 164, and more foam can be generated.

[0068] According to some embodiments of the present application, the foam delivery device 16 comprises a delivery flow path and an impact flow path. The inlet of the delivery flow path is communicated with the outlet of the second waterway 12. The outlet of the delivery flow path is communicated with the liquid outlet end 112. The inlet of the impact flow path is communicated with an external water source. The outlet of the impact flow path is communicated with the delivery flow path.

[0069] Different from the configuration of the foam dispensing device 16 in the above embodiment, the foam dispensing device 16 can also be provided with a dispensing flow path and an impact flow path, the principles of the dispensing flow path and the impact flow path are similar to the principle of the foam generating device 120, wherein the inlet of the dispensing flow path is in communication with the outlet of the second water path 12, the outlet of the dispensing flow path is in communication with the liquid outlet end 112, the mixed liquid flowing out of the foam generating device 120 can enter the dispensing flow path, at this time, the impact flow path in communication with the outside water source can introduce water into the dispensing flow path, so that the mixed liquid in the dispensing flow path is mixed with water again to foam, which can also be simply understood as that the mixed liquid in the dispensing flow path undergoes the foaming process in the foam generating device 120 again, thereby increasing the content of the foam. Similarly, an air inlet structure similar to the air inlet 122 can also be provided on the dispensing flow path. The provision of the dispensing flow path and the impact flow path increases the content of the foam in the mixed liquid flowing out of the liquid outlet end 112, thereby improving the cleaning effect of the dispensing assembly 1 for the laundry treatment apparatus.

[0070] According to some embodiments of the present application, the lower part of the shell 11 is formed with a water outlet channel 1151, and the air suction channel 123 is in communication with the water outlet channel 1151 and the outside of the shell 11. The water outlet channel 1151 can be defined inside the shell 11, at least part of the foam generating device 120 can be located in the water outlet channel 1151 and the outlet of the foam generating device 120 is in communication with the water outlet channel 1151, the foam mixed liquid generated by the foam generating device 120 can flow out through the water outlet channel 1151, which can improve the compactness of the dispensing assembly 1. At least part of the air suction channel 123 extends in the water outlet channel 1151, which can also be understood as that the air suction channel 123 is in communication with the water outlet channel 1151 and the outside of the shell 11. The provision of the air suction channel 123 and the water outlet channel 1151 can hide the air suction channel 123 in the water outlet channel 1151, and the process of the mixed liquid flowing out of the water outlet channel 1151 and the process of the gas flowing through the air suction channel 123 do not affect each other, thereby improving the compactness of the structure of the dispensing assembly 1, reducing the volume of the dispensing assembly 1, and facilitating assembly.

[0071] According to some embodiments of the present application, the shell 11 comprises a shell body 114 and a sub-shell 116, the shell body 114 is formed with the foam generating device 120; the sub-shell 116 is arranged at the bottom of the shell body 114 and defines an air suction groove 1161 open to the outside with the shell body 114, and the air suction channel 123 is in communication with the air suction groove 1161 and the air inlet 122.

[0072] The shell 11 can include a shell body 114 and a sub-shell 116, as shown in FIGS. 10-12, wherein the inside (e.g. bottom) of the shell body 114 is provided with a foam generating device 120 and the like structure; the sub-shell 116 is arranged at the bottom of the shell body 114, and the sub-shell 116 can form a layer of protection for the foam generating device 120, and the sub-shell 116 and the shell body 114 define an air suction groove 1161 in communication with the air suction channel 123, the air suction groove 1161 is open to the outside to realize the communication between the air suction channel 123 and the outside air, and the air suction groove 1161 can make the air enter the main flow path 1200 smoothly, and can improve the foaming efficiency and quality of the mixed liquid in the main flow path 1200.

[0073] In some embodiments, the water outlet channel 1151 is formed in the inside of the bottom wall of the shell 11, and as shown in FIG. 12, the shell 11 includes a shell body 114, a bottom shell 115, and a sub-shell 116, which are arranged in the thickness direction of the dispensing assembly 1 in the order of the shell body 114, the bottom shell 115, and the sub-shell 116, i.e. the bottom shell 115 is arranged at the bottom of the shell body 114, and the sub-shell 116 is arranged at the bottom of the bottom shell 115, and at this time, the bottom shell 115 can be understood as the top wall region of the sub-shell 116 in the above embodiments, and as shown in FIG. 12, the bottom shell 115 and the shell body 114 define the water outlet channel 1151, and the foam generating device 120 and the like structure is located at the bottom of the shell body 114 and at least partially accommodated in the water outlet channel 1151, and the air suction groove 1161 is defined between the bottom shell 115 and the sub-shell 116. Here, the bottom shell 115 is introduced only for describing the specific structure of the shell 11 in the thickness direction, and in other embodiments, the bottom shell 115 can be summarized as a part of the bottom of the shell body 114.

[0074] According to some embodiments of the present application, the top wall of the sub-shell 116 is formed with an air suction hole in communication with the air suction channel 123, and the air suction hole is arranged in the central region of the sub-shell 116.

[0075] The top wall of the sub-shell 116 is formed with an air suction hole, and the air suction hole is in communication with the air suction channel 123, i.e. the two ends of the air suction channel 123 are in communication with the air suction port 122 and the air suction hole respectively, thereby realizing the communication relationship between the main flow path 1200 and the outside air. The air suction hole is located in the central region of the sub-shell 116, as shown in FIGS. 10-12, and the position design of the air suction hole can make the air in the air suction groove 1161 enter the main flow path 1200 from the middle part, thereby improving the air intake efficiency.

[0076] According to some embodiments of the present application, the water outlet channel 1151 is formed between the bottom of the foam generating device 120 and the air suction groove 1161.

[0077] The water outlet passage 1151 is formed between the bottom of the foam generating device 120 and the air suction groove 1161. It can also be understood that at least part of the foam generating device 120 is accommodated in the water outlet passage 1151, and the water outlet passage 1151 is located above the air suction groove 1161. It can be understood that the foam generating device 120, the water outlet passage 1151, and the air suction groove 1161 are at least partially overlapped in the thickness direction of the dispensing assembly 1, which improves the compactness of the dispensing assembly 1 and effectively reduces the volume of the dispensing assembly 1, facilitating the assembly of the dispensing assembly 1.

[0078] The dispensing assembly 1 for the clothes treatment apparatus further comprises a sound-damping member 118 arranged at the inlet of the air suction passage 123 and at least partially opposite to the inlet of the air suction passage 123, so that at least part of the sound-damping member 118 can directly face and affect the airflow flowing into the inlet of the air suction passage 123. Therefore, the gas encounters the sound-damping member 118 before entering the air suction passage 123 through the inlet of the air suction passage 123. The sound-damping member 118 is formed with a plurality of sound-damping holes 1181, so that the gas is forced to disperse and pass through the sound-damping holes 1181 when flowing through the sound-damping member 118, slowing down the flow speed of the gas. By dispersing the airflow and reducing the flow speed, the noise generated when the gas passes through the air suction passage 123 is reduced.

[0079] Therefore, according to the dispensing assembly 1 for the clothes treatment apparatus of the present application, by arranging the sound-damping member 118, the flow speed of the gas is effectively slowed down and the airflow is dispersed, thereby reducing the noise generated when the gas passes through the air suction passage 123.

[0080] According to some embodiments of the present application, as shown in FIGS. 14-19, the dispensing assembly 1 for the clothes treatment apparatus further comprises a housing 11 for accommodating and protecting the internal structure of the dispensing assembly 1 for the clothes treatment apparatus. The housing 11 is formed with a main flow path 1200 and an air suction passage 123, and the main flow path 1200 and the air suction passage 123 are in communication inside the housing 11, so that the gas in the air suction passage 123 can be fully mixed with the washing medium and the water flow in the main flow path 1200, generating a rich foaming effect.

[0081] The air suction passage 123 extends to the surface of the housing 11 to form the inlet of the air suction passage 123 on the surface of the housing 11. Therefore, the air suction passage 123 is not completely enclosed inside the housing 11, but extends from the inside of the housing 11 to the surface of the housing 11, thereby forming the inlet of the air suction passage 123 on the surface of the housing 11. The inlet allows external gas to be sucked into the air suction passage 123.

[0082] The sound-damping member 118 is connected to the surface of the housing 11 so that the sound-damping member 118 at least partially covers the inlet of the air suction passage 123, thereby playing a noise-reducing role. Through the stable connection of the sound-damping member 118 with the housing 11, the sound-damping member 118 can maintain a stable relative position with the inlet of the air suction passage 123, thereby stably and continuously playing a noise-reducing role.

[0083] According to some embodiments of the present application, as shown in FIGS. 15 and 16, the sound-damping member 118 includes a surrounding plate 1182, one end of which is connected to the surface of the housing 11 so that the sound-damping member 118 is fixed to the surface of the housing 11. The surrounding plate 1182 surrounds at least part of the outer periphery of the inlet of the air suction passage 123, thereby effectively guiding and controlling the airflow before the airflow enters the air suction passage 123, reducing unnecessary airflow convection, and thereby reducing noise.

[0084] The sound-damping member 118 further includes a flow-dividing plate 1183 which cooperates with the surrounding plate 1182 to achieve a noise-reducing effect. The flow-dividing plate 1183 is connected to the other end of the surrounding plate 1182 to be spaced apart from the surface of the housing 11, so that the flow-dividing plate 1183 and the surrounding plate 1182 can guide and control the airflow as a whole (sound-damping member 118), and also allow the flow-dividing plate 1183 to maintain a proper spacing from the surface of the housing 11 under the support of the surrounding plate 1182 without hindering the flow of gas at the inlet of the air suction passage 123.

[0085] The flow-dividing plate 1183 is arranged directly opposite the air inlet, so that the flow-dividing plate 1183 can directly face and affect the airflow flowing into the inlet of the air suction passage 123. The flow-dividing plate 1183 is formed with a plurality of sound-damping holes 1181, so that the flow-dividing plate 1183 can disperse the airflow through the plurality of sound-damping holes 1181, thereby reducing noise.

[0086] According to some embodiments of the present application, as shown in FIGS. 14-18, the surrounding plate 1182 surrounds the inlet of the air suction passage 123 at an angle a satisfying 270°≤a≤360°. The angle at which the surrounding plate 1182 surrounds the inlet of the air suction passage 123 represents the included angle of the space formed by the surrounding plate 1182 when it surrounds the inlet of the air suction passage 123.

[0087] When the surrounding plate 1182 completely surrounds the inlet of the air suction passage 123, the angle a is 360°, which can effectively guide and control the airflow while minimizing the convection of the airflow, thereby reducing noise.

[0088] When the surrounding plate 1182 partially surrounds the inlet of the air suction passage 123, the angle a is between 270° and 360°. Although the surrounding plate 1182 does not completely surround the inlet of the air suction passage 123, it can still effectively reduce the convection of the airflow, providing airflow guidance and noise reduction effects.

[0089] According to some embodiments of the present application, the sound reduction hole 1181 is configured as a circular hole, a square hole, an elongated hole or a special-shaped hole. The sound reduction hole 1181 can have different shapes. Specifically, the circular hole has curved edges without straight edges or corners; the square hole is a hole with four edges of equal length and perpendicular to each other; the elongated hole is a hole with a length much greater than the width; and the special-shaped hole is a hole with irregular shape. The circular hole, the square hole and the elongated hole have simple geometric shapes, which are easy to manufacture and process. The special-shaped hole has a more complex geometric shape to optimize the airflow control and noise reduction effect.

[0090] According to some embodiments of the present application, as shown in FIGS. 15 and 16, the second section 1202 includes a throat 12021 which communicates with the air suction channel 123. The throat 12021 is the part of the main flow path 1200 with the smallest cross section. When the water flow in the main flow path 1200 flows through the throat 12021 with a sudden reduction in cross section, the flow rate will increase while the pressure will decrease, forming a low pressure area, promoting the gas to be sucked into the main flow path 1200 through the air suction channel 123.

[0091] The second section 1202 further includes a converging section 12022 which communicates with the throat 12021 and is arranged upstream of the throat 12021, the cross section of the converging section 12022 gradually decreases from upstream to the direction of the throat 12021, which can gradually accelerate the water flow so that the water flow reaches a high flow rate when it reaches the throat 12021.

[0092] The second section 1202 further includes a diverging section 12023 which communicates with the throat 12021 and is arranged downstream of the throat 12021, the cross section of the diverging section 12023 gradually increases from the throat 12021 to the downstream direction, which can gradually decelerate the fluid after it leaves the throat 12021, while the pressure gradually increases, which helps the stable flow of the fluid in the main flow path 1200 and promotes the mixing between the gas and the liquid, producing a foaming effect.

[0093] The water flow enters the main flow path 1200 from the water inlet end 111 and first passes through the converging section 12022. The cross section of the converging section 12022 gradually decreases, forcing the water flow to gradually accelerate, so that the water flow reaches a high flow rate when reaching the throat 12021. The throat 12021 serves as the part with the smallest cross section in the main flow path 1200. When the water flow passes through the throat 12021, the flow rate reaches the maximum, and the pressure decreases significantly, so the throat 12021 has a strong suction effect, promoting the gas to be sucked into the main flow path 1200 through the air suction channel 123. After the water flow and the gas are mixed at the throat 12021, they enter the diverging section 12023 together. The cross section of the diverging section 12023 gradually increases in the downstream direction from the throat 12021, providing space for the fluid to gradually decelerate. In the process of fluid deceleration, the pressure of the fluid gradually increases, which helps to stabilize the flow of the fluid in the main flow path 1200, and also optimizes the interaction between the gas and the water flow, producing a good foaming effect.

[0094] According to some embodiments of the present application, as shown in FIGS. 15 and 16, a dispensing cavity 113 adapted to contain a washing medium is formed in the housing 11, and the dispensing cavity 113 is in communication with the throat 12021, so that the washing medium can flow out of the dispensing cavity 113 under the action of the low pressure of the throat 12021 and enter the main flow path 1200 through the throat 12021. The gas, the washing medium, and the water flow are mixed in the main flow path 1200 to produce a foaming effect.

[0095] According to some embodiments of the present application, a first matching part is provided on the housing 11, which is used to provide a connection point for the sound attenuation piece 118 to cooperate with a second matching part on the sound attenuation piece 118. The second matching part is matched with the first matching part to ensure that the second matching part and the first matching part can be tightly and stably connected together. The second matching part and the first matching part are detachably connected, so they can be easily separated or reconnected, so that the user can easily replace or maintain the sound attenuation piece 118 when needed, which not only improves the flexibility of the dispensing assembly 1 for the clothes treatment apparatus, but also reduces the maintenance cost.

[0096] In some embodiments, a sink 1134 is formed on the bottom wall of the dispensing cavity 113, and a siphon device 15 can be arranged in the sink 1134, as shown in FIG. 7. The outlet of the siphon device 15 is in communication with the water outlet channel 1151. The siphon device 15 can discharge the residual washing medium in the dispensing cavity 113 and the water introduced into the dispensing cavity 113 by the first water path 13 by siphoning, and is used for washing clothes, avoiding the residual of the washing medium and the water in the dispensing cavity 113, and effectively avoiding the problem of secondary pollution of the dispensing cavity 113 caused by the residual medium. In this process, the design of the sink 1134 can improve the ability of the siphon device 15 to siphon the residual washing medium and water in the dispensing cavity 113.

[0097] In some embodiments, as shown in FIG. 7, the siphon device 15 comprises a siphon pipe 151 and a siphon cylinder 152, the siphon pipe 151 is arranged on the bottom wall of the sink 1134, and a first siphon waterway 154 is formed in the siphon pipe 151 to communicate the feeding cavity 113 with the water outlet channel 1151; the siphon cylinder 152 is arranged on at least part of the outer periphery of the siphon pipe 151, and a second siphon waterway 155 is formed between the siphon cylinder 152 and the siphon pipe 151; wherein, the siphon cylinder 152 and the bottom wall of the sink 1134 are left with a siphon gap 153 to communicate the feeding cavity 113 with the second siphon waterway 155.

[0098] In some embodiments, the siphon pipe 151 is arranged on the bottom wall of the sink 1134, and the siphon cylinder 152 is arranged on the outer periphery of the siphon pipe 151 to facilitate the formation of the siphon gap 153 at the bottom wall of the sink 1134, and the residual water and washing materials in the feeding cavity 113 can pass through the siphon gap 153, the second siphon waterway 155 and the first siphon waterway 154 in sequence and then flow into the water outlet channel 1151, and the arrangement position and internal structure of the siphon device 15 ensure that the siphon device 15 can remove the residues at the bottom of the feeding cavity 113, thereby improving the siphon effect.

[0099] In some embodiments, the feeding assembly 1 further comprises a top baffle 117 extending towards the inside of the feeding cavity 113 on the siphon cylinder 152, and the top baffle 117 is provided with a scale line 1171, the position of the scale line 1171 is not higher than the lowest side wall of the feeding cavity 113, or the scale line 1171 is not higher than the standardized highest feeding washing material height of the feeding cavity 113, and meanwhile, it should be noted that the first outlet 1131 also needs to be higher than the bottom wall of the feeding cavity 113, and the height of the scale line 1171 can also be slightly lower than the height of the first outlet 1131 to avoid that the washing materials directly flow out through the first outlet 1131 when feeding and cannot be mixed with the water of the first waterway 13. When the user feeds the washing materials, the scale line 1171 can be used to intuitively judge whether the amount of the feeding washing materials is appropriate, so as to avoid that the washing materials directly flow out from the side wall of the feeding cavity 113 or the first outlet 1131 and affect the washing effect, and the scale line 1171 can improve the user experience.

[0100] In some embodiments, the diameter of the second section 1202 is d1, the diameter of the liquid inlet 121 is d2, and the following condition is satisfied: 0.4≤d2 / d1≤0.45. Since the liquid inlet 121 is arranged on the second section 1202, the size relationship between the liquid inlet 121 and the second section 1202 affects the generation of foam. In some embodiments, if the diameter of the second section 1202 is d1, the diameter of the liquid inlet 121 is d2, and the following condition is satisfied: 0.4≤d2 / d1≤0.45. When d2 / d1<0.4, the diameter of the liquid inlet 121 is smaller than the diameter of the second section 1202, and at this time, the amount of washing agent entering the main flow path 1200 through the liquid inlet 121 is small, which can cause insufficient washing agent in the main flow path 1200, reduce the generated foam, and thus reduce the cleaning effect. When d2 / d1>0.45, the diameter of the liquid inlet 121 is larger than the diameter of the second section 1202, and at this time, the amount of washing agent entering the main flow path 1200 through the liquid inlet 121 is large, which can cause excessive washing agent in the main flow path 1200, and the excessive washing agent cannot be foamed in time before flowing out of the foam generating device 120 due to the limited size of the main flow path 1200, thus reducing the cleaning effect. Therefore, the diameter of the liquid inlet 121 and the diameter of the second section 1202 should be within a suitable range, for example, d2 / d1 can be 0.43, and when d2 / d1=0.43, the foaming effect is better than other values.

[0101] In some embodiments, 2.5mm≤d1≤3.5mm. Since the size of d1 affects the flow rate of washing agent and water in the second section 1202, d1 needs to be kept within a suitable range. In some embodiments, when d1<2.5mm, the diameter of the second section 1202 is too small, and at this time, the flow rate of washing agent and water in the second section 1202 is too fast, and the washing agent and water are difficult to mix fully, the foam generating device 120 generates less foam, and the cleaning effect of the foam generating device 120 is reduced. When d1>3.5mm, the diameter of the liquid inlet 121 is too large, and at this time, the flow rate of washing agent and water in the second section 1202 is too slow, and the mixed liquid after fully mixing has low flow rate and small impact, and the generated foam is also less. Therefore, 2.5mm≤d1≤3.5mm is a suitable range, and in this range, d1 can be 3mm.

[0102] In some embodiments, 1mm≤d2≤1.5mm. Since the size of d2 affects the entry of the washing material into the second section 1202, d2 needs to be kept in a suitable range. In some embodiments, when d2<1mm, the diameter of the liquid inlet 121 is too small, at this time, the rate of the washing material entering the second section 1202 is low, the foam generated by the foam generating device 120 is less, which can cause the cleaning effect of the foam generating device 120 to decrease; when d2>1.5mm, the diameter of the liquid inlet 121 is too large, at this time, the efficiency of the washing material entering the second section 1202 is too fast, and too much washing material enters the foam generating device 120, which can cause the washing material to be wasted and increase the cost. Therefore, 1mm≤d2≤1.5mm is a more suitable range, and in this range, d2 can be 1.3mm.

[0103] In some embodiments, if the diameter of the second section 1202 is d1 and the diameter of the air inlet 122 is d3, then 0.45≤d3 / d1≤0.55 is satisfied. Since the air inlet 122 is arranged on the second section 1202, the size relationship between the air inlet 122 and the second section 1202 can affect the generation of foam. In some embodiments, if the diameter of the second section 1202 is d1 and the diameter of the air inlet 122 is d3, then 0.45≤d3 / d1≤0.55 is satisfied. When d3 / d1<0.45, the diameter of the air inlet 122 is smaller than the diameter of the second section 1202, at this time, the amount of air entering the foam generating device 120 through the air inlet 122 is small, which can cause insufficient gas mixed with the mixed liquid in the foam generating device 120, which can reduce the quality and quantity of the generated foam, and further can cause the cleaning effect to decrease; when d3 / d1>0.55, the diameter of the air inlet 122 is larger than the diameter of the second section 1202, at this time, the air inlet 122 with too large size can easily cause the mixed liquid to leak from the air inlet 122. Therefore, the diameter of the air inlet 122 and the diameter of the second section 1202 should be in a more suitable range, for example, d3 / d1 can be 0.5, when d3 / d1=0.5, the sealing performance is ensured, and the foaming effect is better than other values.

[0104] In some embodiments, 1.2mm≤d3≤2mm. Since the diameter of the air inlet 122 affects the air entering the foam generating device 120, the diameter of the air inlet 122 needs to be set within a suitable range. In some embodiments, when d3<1.2mm, the diameter of the air inlet 122 is too small, at this time, the rate of air entering the second section 1202 is low, the intervention of air is insufficient, the foam generated by the foam generating device 120 is less, which will cause the cleaning effect of the foam generating device 120 to be reduced; when d3>2mm, the diameter of the air inlet 122 is too large, at this time, the washing material and water are easy to leak from the air inlet 122. Therefore, 1.2mm≤d3≤2mm is a more suitable range, and in this range, d3 can be 1.3mm.

[0105] In some embodiments, if the diameter of the second section 1202 is d1, and the diameters of the first section 1201 and the third section 1203 are d4, then 0.35≤d1 / d4≤0.45 is satisfied. Since the second section 1202 is arranged between the first section 1201 and the third section 1203, and the second section 1202 is configured as a variable-diameter section, the relationship between the diameter of the second section 1202 and the diameter of the third section 1203 will affect the foaming effect of the mixed liquid in the foam generating device 120. When d1 / d4<0.35, the second section 1202 is too small compared to the third section 1203, at this time, the flow rate in the second section 1202 is too fast, and the washing material and water entering the second section 1202 cannot be mixed completely in time, which will cause the final generated foam to be reduced; when d1 / d4>0.45, the second section 1202 is too large compared to the third section 1203, at this time, the flow rate change between the second section 1202 and the third section 1203 is small, and the washing material and water are fully mixed due to the small flow rate change in the flow path, which will cause the mixed liquid to be relatively stable, and in turn cause the generated foam to be less. Therefore, 0.35≤d1 / d4≤0.45 is a more suitable range, and in this range, d1 / d4 can be 0.4. It should be noted that the diameter of the first section 1201 and the diameter of the third section 1203 can be the same.
