[0057] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0058] When washing clothes, existing clothing processing equipment usually puts detergents and other detergents directly into the clothing processing chamber of the clothing processing equipment, or puts the detergents into the delivery component and then washes them away with tap water. This method cannot fully dissolve and foam the detergents, and the detergent utilization rate is poor, which will affect the cleaning effect of the clothing processing equipment and the user experience.

[0059] Reference below Figure 1-Figure 12 The delivery component according to the embodiment of the present utility model is described.

[0060] According to the utility model, the dispensing component 1 is suitable for being installed on a workbench of a clothing processing device. The dispensing component 1 includes a shell 11, a first water channel 13 and a second water channel 12. A water inlet end 111 connected to a water source and a liquid outlet end 112 for discharging fluid are formed on the shell 11; the first water channel 13 connects the water inlet end 111 and the liquid outlet end 112, and the second water channel 12 connects the water inlet end 111 and the liquid outlet end 112. A foam generating device 120 is provided in the second water channel 12.

[0061] According to the utility model, the delivery assembly 1 is provided with a shell 11, which is the basic support structure of the delivery assembly 1. The shell 11 can match with the workbench of the clothing processing device to facilitate the installation of the delivery assembly 1, and various parts of the delivery assembly 1 can be arranged inside the shell 11. Specifically, the shell 11 is provided with a water inlet 111 for connecting to a water source and a liquid outlet 112 for discharging a mixed liquid. At least two flow routes suitable for passing water or mixed liquid are arranged in the shell 11, such as a first water channel 13 and a second water channel 12. The first water channel 13 and the second water channel 12 are respectively connected to the water inlet end 111 and the liquid outlet end 112 on the shell 11, wherein a foam generating device 120 is also arranged on the second water channel 12. The foam generating device 120 is a structure for generating foam. When detergent is added to the delivery component 1, a part of the detergent can directly enter the first water channel 13 and flow with the water in the first water channel 13. The water in the first water channel 13 can be mixed with the detergent and then pass through the outlet of the first water channel 13 and finally flow out through the liquid outlet end 112; another part of the detergent can enter the foam generating device 120 in the second water channel 12, and a part of the water entering the delivery component 1 from the water inlet end 111 is fully mixed with the detergent in the foam generating device 120. The mixed liquid foams under the action of the foam generating device 120, and the foamed mixed liquid passes through the outlet of the second water channel 12 and flows out from the liquid outlet end 112. The first water channel 13 and the second water channel 12 can flow out the mixed liquid separately or simultaneously, and the provision of the foam generating device 120 in the second water channel 12 increases the foam in the mixed liquid. Compared with the liquid, the foam has a larger surface structure and can better clean the clothes when it comes into contact with the clothes, thereby effectively improving the washing effect of the clothes processing equipment.

[0062] The dispensing component 1 is installed on the workbench. Compared with other positions of the clothing processing device, the user's operation of the clothing processing device and a series of procedures such as adding detergents can be concentrated in the workbench area, which is convenient for user operation and also convenient for maintenance and disassembly of the dispensing component 1.

[0063] The design of the first water channel 13 and the second water channel 12 can make the delivery component 1 have two different mixed liquid flow routes at the same time, and the two water channels can be used separately or simultaneously. The detergent delivery forms and applicable washing requirements of the two water channels are different. Therefore, in actual situations, different water channels can be selected to be connected or two water channels can be connected at the same time according to different washing requirements, which can provide more choices under the premise of meeting the washing requirements, thereby improving the diversity of the delivery component 1. The foam generating device 120 is provided in the second water channel 12 to enable the mixed liquid to generate more foam, thereby improving the utilization rate of the washing substance. When the same amount of washing substance is used, the mixed liquid that generates more foam has a better cleaning effect. Therefore, the design of the second water channel 12 can reduce the cost of the washing substance usage to a certain extent.

[0064] In some embodiments, the clothing processing device may be a drum washing machine, a pulsator washing machine or other type of laundry equipment, wherein the dispensing assembly 1 of the present invention is particularly suitable for a pulsator washing machine with a vertical axis rotation.

[0065] In some embodiments, the cleaning substance may be a detergent, a softener, a bactericide, or other functional preparations for cleaning.

[0066] According to one embodiment of the utility model, a delivery cavity 113 is formed on the shell 11 , and the inner wall of the delivery cavity 113 forms a first outlet 1131 connected to the liquid outlet 112 and an inlet connected to the first waterway 13 , and the first waterway 13 is connected to the liquid outlet 112 through the delivery cavity 113 .

[0067] During processing, a delivery cavity 113 can be processed in the shell 11. The delivery cavity 113 is a cavity for accommodating detergents. The inner wall of the delivery cavity 113 can be provided with a first outlet 1131 connected to the liquid outlet 112 and an inlet connected to the water inlet 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 deliver detergents into the delivery cavity 113. At least part of the detergents in the delivery cavity 113 can be mixed with the water flow in the first waterway 13 and flow out through the liquid outlet 112 for cleaning clothes. The provision of the delivery cavity 113 facilitates the user to deliver detergents, can optimize the process of the user delivering detergents, does not need to deliver detergents into the flow channel of the first waterway 13, reduces the delivery difficulty, and can improve the user experience. The delivery chamber 113 can be understood as a storage space for washing materials in the delivery component 1. For example, for liquid washing materials, they can be directly poured into the delivery chamber 113, and then the water in the first water channel 13 enters the delivery chamber 113 and mixes with the liquid washing materials before flowing out through the first outlet 1131. For solid detergent, after it is placed in the delivery chamber 113, the water in the first water channel 13 can fully dissolve and mix with the solid washing materials in the delivery chamber 113, and the mixed liquid flows out through the first water channel 13. This design method can ensure that the washing materials can be fully mixed with the water in the first water channel 13, and can improve the washing effect of the delivery component 1.

[0068] In addition, since the detergent only needs to be put into the delivery cavity 113, the detergent will not contaminate other structures of the delivery component 1, avoiding the detergent remaining between the various structures inside the delivery component 1, and avoiding secondary contamination of the delivery component 1 when in use.

[0069] According to an embodiment of the utility model, the first water channel 13 includes a first flow channel section, one end of which is connected to the water inlet end 111 , and the other end of which is connected to the delivery cavity 113 through an inlet, and the inlet is arranged on the side wall of the delivery cavity 113 . The first water channel 13 connects the water inlet end 111 with the liquid outlet end 112 through the delivery chamber 113. It can be simply understood that the delivery chamber 113 divides the first water channel 13 into two sections. The first water channel 13 between the delivery chamber 113 and the water inlet end 111 can be understood as a first flow channel section. The first flow channel section can be connected to the inlet on the delivery chamber 113. It should be noted that the inlet position of the delivery chamber 113 can be set on the side wall of the delivery chamber 113. When the user delivers detergent into the delivery chamber 113, water enters the water inlet end 111, and a part of the water flows into the delivery chamber 113 through the first flow channel section. At this time, since the inlet of the delivery chamber 113 is located on the side wall of the delivery chamber 113, the water flow of the first flow channel section can impact the delivery chamber 113 from the side wall of the delivery chamber 113 so that the water flow and the detergent are fully mixed. At the same time, the detergent remaining on the side wall of the delivery chamber 113 can also be rinsed clean, thereby reducing the residual detergent in the delivery chamber 113.

[0070] In some embodiments, the delivery chamber 113 may be defined by a partition structure to form a first sub-chamber 1132 and a second sub-chamber 1133 spaced apart from each other. In this case, the first flow channel section may be correspondingly divided into a first sub-waterway 131 and a second sub-waterway 132. Figure 5 As shown, the first sub-waterway 131 and the second sub-waterway 132 are arranged around the first sub-cavity 1132 and the second sub-cavity 1133 respectively, the first sub-cavity 1132 is provided with a first inlet 1311, and the second sub-cavity 1133 is provided with a second inlet 1321, the first sub-waterway 131 and the second sub-waterway 132 are connected with the first inlet 1311 and the second inlet 1321 respectively, and a guide plate 133 extending toward the first sub-cavity 1132 can also be provided on the first inlet 1311, and the guide plate 133 can guide the water flowing in the first waterway 13 to 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 guide plate 133 can also be provided at the position of the second inlet 1321, and the number of the first inlet 1311 and the second inlet 1321 can be increased or decreased according to actual conditions, and multiple first inlets 1311 and multiple second inlets 1321 can flush the side walls of the corresponding sub-cavities from more angles.

[0071] According to an embodiment of the utility model, the first water channel 13 further includes a second flow channel section, one end of which is connected to the first outlet 1131, and the other end of which is connected to the liquid outlet 112. Corresponding to the first flow channel section, the first water channel 13 further includes a second flow channel section, and the second flow channel section connects the delivery chamber 113 with the liquid outlet 112. It can also be understood that: the inlet of the second flow channel section is connected to the first outlet 1131 in the delivery chamber 113, and the water flowing into the first water channel 13 from the water inlet end 111 is mixed with the detergent in the delivery chamber 113, flows to the second flow channel section through the first outlet 1131, and finally flows out through the liquid outlet 112. Figure 5 As shown, 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, that is, 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 arrangement of the first outlet 1131 does not require the first outlet 1131 to be arranged in each sub-cavity, which can reduce the difficulty of processing.

[0072] According to one embodiment of the utility model, the foam generating device 120 includes a main flow path 1200 and a liquid inlet flow path 124. The main flow path 1200 is arranged in the second water path 12 and is located between the water inlet end 111 and the liquid outlet end 112. A liquid inlet 121 is provided on the main flow path 1200. One end of the liquid inlet flow path 124 is connected to the liquid inlet 121, and the other end is connected to the delivery chamber 113 on the shell 11. The liquid inlet flow path 124 is used to connect the delivery chamber 113 with the main flow path 1200.

[0073] The foam generating device 120 is provided with a main flow path 1200 and a liquid inlet flow path 124, wherein the main flow path 1200 is the main body of the foam generating device 120, and the main flow path 1200 is connected with the water inlet end 111 and the liquid outlet end 112, and a 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 connects the delivery chamber 113 with the main flow path 1200, and specifically, the main flow path 1200 is provided with a liquid inlet port 121, and the liquid inlet port 121 can be connected with the delivery chamber 113. The delivery chamber 113 is connected to realize the connection between the delivery chamber 113 and the main flow path 1200. When the detergent is delivered into the delivery chamber 113, a part of the detergent can flow into the main flow path 1200 from the liquid inlet 121 through the liquid inlet flow path 124. The detergent flowing into the main flow path 1200 is mixed with the water entering the main flow path 1200 from the water inlet end 111, and a large amount of foam can be generated under the action of the foam generating device 120. The mixed liquid mixed with foam can be used to clean the objects to be washed after flowing out through the liquid outlet end 112. The provision of the liquid inlet flow path 124 and the main flow path 1200 can distinguish the routes of clean water and detergent in the second flow path. The detergent in the delivery chamber 113 is introduced into the foam generating device 120 through the liquid inlet flow path 124, which can reduce the difficulty of directly delivering the detergent into the foam generating device 120. The user only needs to deliver the detergent into the delivery chamber 113 to complete the delivery of the detergent in the first water path 13 and the second water path 12. The operation is simple and convenient.

[0074] According to an embodiment of the utility model, the foam generating device 120 further includes: an air suction channel 123, one end of which is connected to the air suction port 122 of the main flow path 1200, and the other end of which is connected to the outside of the housing 11. Specifically, the main flow path 1200 is formed with an air suction port 122, and the foam generating device 120 can also be provided with an air suction channel 123 that connects the air suction port 122 with the outside. When the foam generating device 120 is used, the detergent 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 detergent and the water flow are foamed in the foam generating device 120, the amount of foam can be increased due to the intervention of air, so that the foam generating device 120 generates more foam, thereby improving the cleaning effect of the second water path 12. In addition, after entering the mainstream path 1200, the air can also be retained inside the foam, thereby improving the stability of the foam, increasing the retention time of the foam, and further improving the washing effect.

[0075] According to an embodiment of the utility model, the air inlet 122 and the liquid inlet 121 are at least partially opposite to each other 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 to each other. Since the air inlet 122 and the liquid inlet hole are at least partially opposite to each other in the radial direction of the main flow path 1200, when the washing material flows into the main flow path 1200 through the liquid inlet hole, the external air can directly enter the main flow path 1200 through the air inlet 122, ensuring that the air and the mixed liquid are fully contacted and mixed in the main flow path 1200, thereby generating more and more stable foam.

[0076] According to one embodiment of the utility model, the main flow path 1200 includes a first section 1201 and a second section 1202, one end of the first section 1201 is connected to the water inlet end 111; one end of the second section 1202 is connected to the other end of the first section 1201, and the second section 1202 is provided with an air intake port 122 and a liquid inlet port 121; wherein the diameter of the second section 1202 is smaller than the diameter of the first section 1201.

[0077] Specifically, the main flow path 1200 is provided with a first section 1201 and a second section 1202 connected in sequence, wherein the first section 1201 is connected to the water inlet end 111; the second section 1202 is connected to the liquid outlet end 112, and a portion of water entering the water inlet end 111 can flow through the first section 1201 and the second section 1202 in sequence and then flow out from the liquid outlet end 112. During this process, the detergent in the delivery cavity 113 can enter the second section 1202 through the liquid inlet 121 on the second section 1202, and at the same time, the outside air can enter the second section 1202 through the air intake port 122, and the detergent, air and water are mixed in the main flow path 1200. The diameter of the second section 1202 is smaller than the diameters of the first section 1201 and the third section 1203. Therefore, the flow rate in the second section 1202 is large, and a low-pressure area relative to the first section 1201 can be formed in the second section 1202, which can increase the rate at which air enters 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 produce a large amount of foam. The mixed liquid mixed with foam flows from the outlet of the second section 1202 through the liquid outlet end 112 and then flows out for cleaning the objects to be washed, thereby achieving a better cleaning effect.

[0078] According to one embodiment of the utility model, the main flow path 1200 also includes: a third section 1203, one end of the third section 1203 is connected to the other end of the second section 1202, and the other end of the third section 1203 is connected to the liquid outlet 112; and the diameter of the third section 1203 is greater than the diameter of the second section 1202. Specifically, the main flow path 1200 can also be provided with a third section 1203. The third section 1203 can be provided between the second section 1202 and the liquid outlet end 112 and connect the second section 1202 with the liquid outlet end 112. The mixed liquid mixed with foam flows out from the outlet of the second section 1202 and enters the third section 1203. The diameter of the third section 1203 is larger than that of the second section 1202. Therefore, the flow rate of the mixed liquid in the third section 1203 is slower than the flow rate of the mixed liquid in the second section 1202. At this time, the foam mixed liquid flows relatively smoothly in the third section 1203, which can reduce the risk of foam bursting and ensure that the foam can act intactly on the laundry, thereby improving the cleaning effect of the dispensing component 1.

[0079] According to one embodiment of the utility model, the second water channel 12 includes a third flow channel section and a fourth flow channel section, one end of the third flow channel section is connected to the water inlet end 111, and the other end of the third flow channel section is connected to one end of the first section 1201; one end of the fourth flow channel section is connected to the other end of the third section 1203, and the other end of the fourth flow channel section is connected to the liquid outlet end 112.

[0080] The second water channel 12 flows through the foam generating device 120, so it can be simply understood that the foam generating device 120 divides the second water channel 12 into a third flow channel section and a fourth flow channel section, wherein the third flow channel section connects the water inlet end 111 with the foam generating device 120; and the fourth flow channel section connects the foam generating device 120 with the liquid outlet end 112. The arrangement of the third flow channel section and the fourth flow channel section makes the path of the second water channel 12 clearer, and the flow path of the second flow channel can also be adjusted according to the specific structural adaptability of the actual delivery component 1, so that the flow of the mixed liquid can be more accurately controlled.

[0081] According to an embodiment of the present invention, a second outlet 1136 is provided at the bottom of the delivery chamber 113, and the second outlet 1136 is connected to the liquid inlet 121 to define the 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 delivery chamber 113. Specifically, the first outlet 1131 needs to be higher than the bottom of the delivery chamber 113 to avoid the washing material flowing out directly through the first outlet 1131 when the washing material is delivered. The second outlet 1136 needs to be provided at the bottom of the delivery chamber 113, so that the washing material can flow out of the delivery chamber 113 and enter the main flow path 1200 by gravity, thereby increasing the speed at which the washing material enters the main flow path 1200 and reducing the residual washing material in the delivery chamber 113.

[0082] According to one embodiment of the utility model, the delivery component 1 further includes: a switching device, which can selectively connect at least one of the first waterway 13 and the second waterway 12 to the water inlet end 111. The switching device can be arranged at the water inlet end 111 and located upstream of the inlet of the first waterway 13 and the inlet of the second waterway 12, that is, the switching device can control the connection or closing between the first waterway 13 and the second waterway 12 and the water inlet end 111. For example, the switching device can control the connection between the first waterway 13 and the water inlet end 111 and close the second waterway 12; or the switching device can also control the first waterway 13 to be closed and the second waterway 12 to be connected; or the switching device can also control the first waterway 13 and the second waterway 12 to be connected to the water inlet end 111 at the same time, and the specific control situation can be determined according to actual needs. The setting of the switching device allows the delivery component 1 to flexibly select the first waterway 13 and the second waterway 12 according to needs, making the delivery component 1 more controllable and flexible.

[0083] According to one embodiment of the present invention, the switching device is constructed as an on-off valve, which is arranged in the first water channel 13 and can selectively open or close the first water channel 13, and / or the on-off valve is arranged in the second water channel 12 and can selectively open or close the second water channel 12.

[0084] The construction of the switching device will affect the control of the first water channel 13 and the second water channel 12 by the delivery component 1. For example, the switching device can be constructed as an on-off valve, and the on-off valve can be constructed as two valves corresponding to the first water channel 13 and the second water channel 12, and respectively control the opening or closing of the first water channel 13 and the opening or closing of the second water channel 12. Specifically, an on-off valve can be set between the first water channel 13 and the water inlet end 111, and similarly, an on-off valve can also be set between the second water channel 12 and the water inlet end 111. The setting of the two on-off valves enables the control of the on and off states of the first water channel 13 and the second water channel 12 to be independent, and the corresponding water channel can be selected for use according to needs, and the states between the two water channels will not affect each other.

[0085] According to one embodiment of the utility model, the switching device is constructed as a reversing valve 14, and the reversing valve 14 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 connected to the water inlet end 111, the second valve port 142 is connected to the inlet of the first waterway 13, and the third valve port 143 is connected to the inlet of the second waterway 12; wherein, 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.

[0086] Different from the on-off valve in the above embodiment, the switching device can also be configured as a reversing valve 14, such as Figure 4 , Figure 5 and Figure 6As shown, the reversing valve 14 has three valve ports, namely, a first valve port 141, a second valve port 142 and a third valve port 143, wherein the first valve port 141 is the inlet of the reversing valve 14, and the first valve port 141 is connected to the water inlet end 111; the second valve port 142 is the outlet of the reversing valve 14, and the second valve port 142 is connected to the first waterway 13; the third valve port 143 is also the outlet of the reversing valve 14, and the third valve port 143 is connected to the inlet of the second waterway 12. The reversing valve 14 can control the first valve port 141 to be connected to the second valve port 142 or control the first valve port 141 to be connected to the third valve port 143 according to the cleaning requirements, and the reversing valve 14 is more convenient to operate when a single waterway is selected.

[0087] In some embodiments, when the switching device adopts a reversing valve 14 structure, such as Fig. 9 As shown, the shell 11 can be provided with a first cavity 1141, a second cavity 1142 and a third cavity 1143 corresponding to each other in the communicating 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 communicated with the water inlet end 111 through the first cavity 1141, the second valve port 142 is communicated with the first waterway 13 through the second cavity 1142, and the third valve port 143 is communicated with the second waterway 12 through the third cavity 1143. The arrangement of the three cavities enables the first waterway 13, the second waterway 12 and the waterway of the water inlet end 111 of the delivery component 1 to be adaptively changed in the thickness direction of the delivery component 1, so as to adjust the layout of the internal structure of the delivery component 1. For example, the second waterway 12 is located at the bottom of the delivery cavity 113. At this time, the third cavity 1143 extends in the thickness direction of the delivery component 1, and the water flowing out of the reversing valve 14 can be diverted to the second waterway 12 at the bottom of the delivery component 1, thereby improving the compactness of the delivery component 1.

[0088] According to an embodiment of the utility model, the delivery component 1 further includes: a foam delivery device 16, which is disposed on the housing 11, and connects the outlet of the second water channel 12 with the liquid outlet 112 to increase the foam of the mixed liquid flowing out of the second water channel 12.

[0089] A foam delivery device 16 can also be arranged between the foam generating device 120 and the water outlet. The foam delivery device 16 can be used to further increase the foam content in 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 setting of the foam delivery device 16 can foam the mixed liquid flowing out of the foam generating device 120 again, increase the foam content, and further improve the cleaning effect of the delivery component 1.

[0090] According to one embodiment of the utility model, the foam delivery device 16 includes a cylinder 164 and a spiral blade 165, at least one end of the cylinder 164 is respectively provided with a bubble outlet connected to the liquid outlet 112, at least one end of the cylinder 164 or between the two ends is provided with a bubble inlet 163 connected to the outlet of the second waterway 12; the spiral blade 165 is fixedly arranged in the cylinder 164.

[0091] like Figure 4 As shown, the foam delivery device 16 is provided with a cylinder 164 and a spiral blade 165, wherein a cavity for accommodating the spiral blade 165 is formed in the cylinder 164, and the spiral blade 165 is fixedly arranged in the cavity of the cylinder 164. The spiral blade 165 can be used to cut the water flow, and the foam delivery device 16 can be connected with the outlet of the second waterway 12 through a bubble inlet 163 between the two ends of the cylinder 164 (for example, in the middle position), and the mixed liquid flowing out of the foam generating device 120 can enter the cylinder 164 through the bubble inlet 163, and generate more foam under the action of the spiral blade 165, and the mixed liquid mixed with more foam can flow to the liquid outlet 112 from the first bubble outlet 161 and the second bubble outlet 162 at the two ends of the cylinder 164.

[0092] In some embodiments, a rotatable spiral impeller may be disposed in the cylinder 164 , and the mixed liquid in the cylinder 164 may be stirred by the rotation of the spiral impeller, and more foam may also be generated.

[0093] According to one embodiment of the utility model, the foam delivery device 16 includes a delivery flow path and an impact flow path, the inlet of the delivery flow path is connected to the outlet of the second water path 12, and the outlet of the delivery flow path is connected to the liquid outlet end 112; the inlet of the impact flow path is connected to an external water source, and the outlet of the impact flow path is connected to the delivery flow path.

[0094] Different from the construction mode of the foam delivery device 16 in the above-mentioned embodiment, the foam delivery device 16 can also be provided with a delivery flow path and an impact flow path. The principle of the delivery flow path and the impact flow path is similar to that of the foam generating device 120, wherein the inlet of the delivery flow path is connected to the outlet of the second water path 12, and the outlet of the delivery flow path is connected to the liquid outlet end 112. The mixed liquid flowing out of the foam generating device 120 can enter the delivery flow path. At this time, the impact flow path connected to the external water source can introduce water into the delivery flow path, so that the mixed liquid in the delivery flow path is mixed with water again to foam. It can also be simply understood that the mixed liquid performs the foaming process in the foam generating device 120 again in the delivery flow path, further increasing the content of foam. Similarly, an air intake structure similar to the air inlet 122 can also be provided on the delivery flow path. The provision of the delivery flow path and the impact flow path further increases the content of foam in the mixed liquid finally flowing out of the liquid outlet end 112, thereby improving the cleaning effect of the delivery component 1.

[0095] The pulsator washing machine according to the utility model is briefly described below.

[0096] According to the utility model, a workbench is provided on the pulsator washing machine, and an installation cavity suitable for accommodating a dispensing component 1 is formed on the workbench. The dispensing component 1 is constructed as the dispensing component 1 in the above embodiment. Since the pulsator washing machine according to the utility model is provided with the dispensing component 1 in the above embodiment, during assembly, the dispensing component 1 can be assembled into the installation cavity, and the mixed liquid can be fully foamed through two different methods of the first water channel 13 and the second water channel 12, thereby improving the cleaning effect of the pulsator washing machine. At the same time, the dispensing component 1 is assembled to the workbench, which is convenient for users to operate and improves the user experience.

[0097] In some embodiments, the dispensing assembly 1 can also be used in other types of washing machines and is not limited to pulsator washing machines.

[0098] According to an embodiment of the utility model, the pulsator washing machine includes a clothing processing chamber, and the liquid outlet 112 is connected to the clothing processing chamber. The pulsator washing machine is provided with a clothing processing chamber, and when the dispensing assembly 1 is assembled to the installation chamber, the liquid outlet 112 of the dispensing assembly 1 faces the clothing processing chamber and is connected to the clothing processing chamber, ensuring that the foam mixed liquid generated by the dispensing assembly 1 can directly enter the clothing processing chamber for cleaning clothing.

[0099] In some embodiments, a water outlet channel 1151 is formed inside the bottom wall of the shell 11, and the outlet of the water outlet channel 1151 can be understood as the liquid outlet end 112 of the delivery component 1, and the first outlet 1131 of the delivery chamber 113 and the outlet of the foam delivery component 1 can be connected to the water outlet channel 1151. It can also be understood that the mixed liquid of the first water channel 13 and the mixed liquid of the second water channel 12 can eventually flow into the clothing processing chamber through the water outlet channel 1151 to realize the process of cleaning clothes.

[0100] In some embodiments, the housing 11 may include a housing body 114 and a sub-housing 116. Figure 10-12 As shown, the interior (for example, the bottom) of the shell body 114 is provided with structures such as a foam generating device 120 and a foam dispensing device 16; the sub-shell 116 is arranged below the shell body 114, and the sub-shell 116 can form a layer of protection for the foam generating device 120, and an air suction groove 1161 connected to the air suction channel 123 is defined between the sub-shell 116 and the shell body 114, and the air suction groove 1161 is open to the outside to realize the connection between the air suction channel 123 and the outside air. The setting of the air suction groove 1161 can make the air enter the main flow path 1200 smoothly, and can improve the foaming efficiency and foaming quality of the mixed liquid in the main flow path 1200.

[0101] In some embodiments, an air intake hole is formed on the top wall of the sub-shell 116, and the air intake hole is connected to the air intake channel 123, that is, the two ends of the air intake channel 123 are respectively connected to the air intake port 122 and the air intake hole, thereby realizing the connection between the main flow path 1200 and the external air. The air intake hole is located in the central area of ​​the sub-shell 116, such as Figure 10-12 As shown, the position design of the air intake hole enables the air in the air intake groove 1161 to enter the main flow path 1200 from the middle, thereby improving the air intake efficiency.

[0102] In some embodiments, the water outlet channel 1151 is formed at the bottom of the foam generating device 120, which can also be understood as at least part of the foam generating device 120 being accommodated in the water outlet channel 1151, and the water outlet channel 1151 being located at the top of the air suction groove 1161. It can be understood that the foam generating device 120, the water outlet channel 1151 and the air suction groove 1161 are at least partially overlapped in sequence in the thickness direction of the delivery component 1, which improves the compactness of the delivery component 1, can effectively reduce the volume of the delivery component 1, and facilitates the assembly of the delivery component 1.

[0103] In some embodiments, the water outlet channel 1151 is formed inside the bottom wall of the housing 11, which can also be understood as follows: Fig.12 As shown, the housing 11 includes a housing body 114, a bottom housing 115 and a sub-housing 116. In the thickness direction of the delivery assembly 1, the housing body 114, the bottom housing 115 and the sub-housing 116 are arranged in sequence, that is, the bottom housing 115 is arranged at the lower part of the housing body 114, and the sub-housing 116 is arranged at the lower part of the bottom housing 115. At this time, the bottom housing 115 can also be understood as the top wall area of ​​the sub-housing 116 in the above embodiment, as shown in FIG. Fig.12 As shown in the figure, a water outlet channel 1151 is defined between the bottom shell 115 and the shell body 114, and structures such as the foam generating device 120 and the foam dispensing device 16 are located at the bottom of the shell body 114 and at least partially accommodated in the water outlet channel 1151, and an air suction groove 1161 is defined between the bottom shell 115 and the sub-shell 116. The bottom shell 115 is introduced here only to describe the specific structure of the shell 11 in the thickness direction. In other embodiments, the bottom shell 115 can also be summarized as a part of the bottom of the shell body 114.

[0104] In some embodiments, a sink 1134 is formed on the bottom wall of the delivery chamber 113, and a siphon device 15 may be disposed in the sink 1134. Figure 7As shown, the outlet of the siphon device 15 is connected to the water outlet channel 1151, and the siphon device 15 can discharge the residual detergent in the delivery chamber 113 and the water introduced into the delivery chamber 113 by the first waterway 13 through siphoning, and use them for washing clothes, thereby avoiding the residual detergent and water in the delivery chamber 113, and effectively avoiding the problem of secondary pollution of the delivery chamber 113 caused by the residual substances. In this process, the purpose of designing the sink 1134 is to improve the ability of the siphon device 15 to siphon the residual detergent and water in the delivery chamber 113.

[0105] In some embodiments, Figure 7 As shown, the siphon device 15 includes: a siphon tube 151 and a siphon cylinder 152. The siphon tube 151 is arranged on the bottom wall of the trough 1134. A first siphon waterway 154 is formed in the siphon tube 151 to connect the delivery cavity 113 with the water outlet channel 1151; the siphon cylinder 152 is covered on at least part of the outer periphery of the siphon tube 151, and a second siphon waterway 155 is formed between the siphon cylinder 152 and the siphon tube 151; wherein, a siphon gap 153 is reserved between the siphon cylinder 152 and the bottom wall of the trough 1134 to connect the delivery cavity 113 with the second siphon waterway 155.

[0106] Specifically, the siphon tube 151 is arranged on the bottom wall of the trough 1134, and the siphon tube 152 is sleeved on the outer periphery of the siphon tube 151 to form a siphon gap 153 at the bottom wall of the trough 1134. The residual water and detergents in the delivery chamber 113 can pass through the siphon gap 153 in turn through the second siphon waterway 155 and the first siphon waterway 154 and then flow into the water outlet channel 1151. The setting position and internal structure of the siphon device 15 ensure that the siphon device 15 can remove the residues at the bottom of the delivery chamber 113, thereby improving the siphon effect.

[0107] In some embodiments, the dispensing assembly 1 is further provided with a top baffle 117 extending toward the inside of the dispensing chamber 113 on the siphon tube 152, and a scale line 1171 is provided on the top baffle 117, and the position of the scale line 1171 is not higher than the lowest side wall of the dispensing chamber 113, or the scale line 1171 is not higher than the standardized maximum height of the dispensing detergent in the dispensing chamber 113. At the same time, it should be noted that the first outlet 1131 also needs to be higher than the bottom wall of the dispensing chamber 113, and the height of the scale line 1171 can also be slightly lower than the height of the first outlet 1131, so as to prevent the detergent from flowing out directly through the first outlet 1131 when being dispensed and unable to mix with the water in the first waterway 13. When the user dispenses the detergent, the scale line 1171 can be used to intuitively judge whether the amount of detergent dispensed is appropriate, so as to prevent excessive detergent from flowing out directly from the side wall of the dispensing chamber 113 or the first outlet 1131 and affecting the washing effect, and the setting of the scale line 1171 can improve the user experience.

[0108] In some embodiments, the diameter of the second section 1202 is d1, the diameter of the liquid inlet 121 is d2, and the following relationship is satisfied: 0.4≤d2 / d1≤0.45. Since the liquid inlet 121 is disposed in the second section 1202, the size relationship between the liquid inlet 121 and the second section 1202 affects the generation of foam. Specifically, if the diameter of the second section 1202 is d1, and the diameter of the liquid inlet 121 is d2, the following relationship is satisfied: 0.4≤d2 / d1≤0.45. Among them, when d2 / d1<0.4, the diameter of the liquid inlet 121 is smaller than the diameter of the second section 1202. At this time, the amount of detergent entering the main channel 1200 through the liquid inlet 121 is small, which will lead to insufficient detergent in the main channel 1200, reduce the generated foam, and then lead to a decrease in the washing effect; when d2 / d1>0.45, the diameter of the liquid inlet 121 is larger than the diameter of the second section 1202. At this time, the amount of detergent entering the main channel 1200 through the liquid inlet 121 is large, which will lead to excessive detergent in the main channel 1200. Due to the limited size of the main channel 1200, the excessive detergent cannot be foamed in time before flowing out of the foam generating device 120, thereby reducing the washing effect. Therefore, the diameter of the liquid inlet 121 and the diameter of the second section 1202 should be in a relatively suitable range. For example, d2 / d1 is preferably 0.43. When d2 / d1=0.43, the foaming effect is better than other values.

[0109] In some embodiments, 2.5mm≤d1≤3.5mm. Since the size of d1 will affect the flow rate of the detergent and water in the second section 1202, d1 needs to be maintained in an appropriate range. Specifically, when d1<2.5mm, the diameter of the second section 1202 is too small. At this time, the flow rate of the detergent and water in the second section 1202 is too fast, and the detergent and water are difficult to fully mix. The foam generating device 120 generates less foam, which will reduce the cleaning effect of the foam generating device 120; when d1>3.5mm, the diameter of the liquid inlet 121 is too large. At this time, the flow rate of the detergent and water in the second section 1202 is too slow. The mixed liquid after full mixing has a low flow rate and a small impact force, and generates less foam. Therefore, 2.5mm≤d1≤3.5mm is a more appropriate range. Within this range, d1 can preferably be 3mm.

[0110] In some embodiments, 1mm≤d2≤1.5mm. Since the size of d2 will affect the entry of the detergent into the second section 1202, d2 needs to be maintained in an appropriate range. Specifically, when d2<1mm, the diameter of the liquid inlet 121 is too small. At this time, the rate at which the detergent enters the second section 1202 is low, and the foam generating device 120 generates less foam, which will cause the cleaning effect of the foam generating device 120 to be reduced; when d2>1.5mm, the diameter of the liquid inlet 121 is too large. At this time, the efficiency of the detergent entering the second section 1202 is too fast, and too much detergent enters the foam generating device 120, which will cause the room charge of the detergent and increase the cost. Therefore, 1mm≤d2≤1.5mm is a more appropriate range. Within this range, d2 can preferably be 1.3mm.

[0111] 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 disposed in the second section 1202, the size relationship between the air inlet 122 and the second section 1202 affects the generation of foam. Specifically, 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. Among them, 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 will lead to insufficient gas mixed with the mixed liquid in the foam generating device 120, which will reduce the quality and quantity of the generated foam, and then lead to a decrease in the washing effect; 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 oversized air inlet 122 is likely to cause the mixed liquid to leak from the air inlet 122. Therefore, the diameter of the air inlet 122 should be in a relatively suitable range with the diameter of the second section 1202. For example, d3 / d1 is preferably 0.5. When d3 / d1=0.5, while ensuring the sealing performance, the foaming effect is better than other values.

[0112] In some embodiments, 1.2mm≤d3≤2mm. Since the diameter of the air intake port 122 affects the air entering the foam generating device 120, the diameter of the air intake port 122 needs to be set within a suitable range. Specifically, when d3<1.2mm, the diameter of the air intake port 122 is too small. At this time, the rate at which air enters the second section 1202 is low, and the foam generating device 120 generates less foam due to the lack of air intervention, which will reduce the cleaning effect of the foam generating device 120; when d3>2mm, the diameter of the air intake port 122 is too large. At this time, detergents and water are easy to leak from the air intake port 122. Therefore, 1.2mm≤d3≤2mm is a more suitable range, and within this range, d3 can preferably be 1.3mm.

[0113] 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 disposed 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 detergent and water entering the second section 1202 cannot be mixed completely in time, which will result in a reduction in the final foam produced; when d1 / d4>0.45, the second section 1202 is too large compared to the third section 1203. At this time, the flow rate between the second section 1202 and the third section 1203 changes very little, and the detergent and water are fully mixed. Due to the small change in the flow rate on the flow path, the mixed liquid will be relatively stable, resulting in less foam. Therefore, 0.35≤d1 / d4≤0.45 is a more suitable range. In this range, d1 / d4=0.4 can be preferably selected. It should be noted that the diameter of the first section 1201 and the diameter of the third section 1203 can be the same.

[0114] In summary, the delivery component 1 defines a delivery chamber 113 in the shell 11, and a water outlet channel 1151 is provided at the bottom of the delivery chamber 113, as well as a foam generating device 120 and a foam delivery device 16 which are at least partially located in the water outlet channel 1151 and are connected to each other. The delivery component 1 connects the first waterway 13 and the second waterway 12 through a switching device, wherein the first waterway 13 flows through the delivery chamber 113, and the second waterway 12 flows through the foam generating device 120 and the foam delivery device 16. The switching device can be used to select the first waterway 13 and the second waterway 12 according to needs, thereby improving the flexibility of the delivery component 1. The foam generating device 120 is provided with a liquid inlet 121, and the detergent in the delivery chamber 113 can be introduced into the main flow path 1200 of the foam generating device 120 through the liquid inlet flow path 124. The detergent entering the main flow path 1200 can be mixed with the water entering the main flow path 1200 from the water inlet end 111 and the air introduced from the air intake channel 123 to form foam. The foamed mixed liquid generates more foam after the action of the foam delivery device 16 and is finally used to wash clothes, which can effectively improve the washing effect of the delivery component 1.
