[0046] The second pipe 150 is connected to the foamer 110 and is used to introduce the foamed washing water and detergent into the washing inner drum.

[0047] In the technical solution of the embodiment of the present application, the detergent in the detergent box 130 is pumped into the foamer 110 by the pump 140, and the washing water enters the foamer 110 through the first pipe 120. The washing water and the detergent are pre-mixed and foamed in the foamer 110 to form a foamed mixture of washing water and detergent, and then transported to the washing inner drum by the second pipe 150, so that the detergent entering the washing inner drum has been dissolved in the water and forms a foamy mixture, so there is no need to increase the rotation time of the washing inner drum to dissolve the detergent, thereby reducing the energy consumption of the washing machine.

[0048] In some embodiments, the foamer 110 may also be an ultrasonic foamer 110 or a plurality of foaming columns may be disposed in the foamer 110 .

In an embodiment, the liquid inlet direction of the first interface 113 and the water inlet direction of the second interface 115 are arranged at an angle to each other, so that the washing water and the detergent can at least form partial convection, thereby improving the dissolution efficiency of the detergent.

[0050] In some embodiments, the liquid inlet direction of the first interface 113 and the water inlet direction of the second interface 115 are at 90° to each other; in other embodiments, the liquid inlet direction of the first interface 113 and the water inlet direction of the second interface 115 are set at an acute angle to each other.

In this embodiment, the amount of washing water required is large, and it needs to flow while dissolving the detergent; the washing water flowing into the foamer 110 through the first pipe 120 can flow along the axial direction of the foamer 110 (such as Figure 7 As shown, α flow), to ensure that the flow path of the washing water does not undergo too large a reverse change; the flow resistance of the washing water can be reduced; and the detergent flows into the foamer 110 from the side and mixes with the washing water (as shown Figure 7 middle β1, β2 flow).

[0052] In the embodiment, the foamer 110 is cylindrical, having two opposite ends and a side, one of which is used to set a second interface 115 connected to the first pipe 120, and the other is used to set a fourth interface 116 connected to the second pipe 150. The washing water flows along the axial direction.

[0053] In addition, in some embodiments, the detergent box 130 can be arranged on the upper side of the foamer 110, and the pump 140 can be installed on the detergent box 130. The foamer 110 is installed horizontally (its axial direction is parallel to the horizontal direction). In this structure, the second interface 115 is arranged at the end of the foamer 110, so that the first pipe 120 is connected to the foamer 110 substantially along the horizontal direction; the first interface 113 is arranged on the side of the foamer 110, so that the pump 140 is connected to the first interface 113, which is conducive to saving space of the washing device 10.

[0054] As an optional implementation of the above embodiment, Figure 2 ,like Figure 3 He Ru Figure 4 As shown, the detergent box 130 is provided with a first accommodating chamber S1 and a second accommodating chamber S2 separated from each other; the first accommodating chamber S1 is used to accommodate a first type of detergent, and the second accommodating chamber S2 is used to accommodate a second type of detergent. The foamer 110 also includes a third interface 114; the pump 140 is configured to pump the first type of detergent from the first interface 113 pump 140 into the foamer 110 and pump the second type of detergent from the third interface 114 pump 140 into the foamer 110. In this embodiment, the first accommodating chamber S1 and the second accommodating chamber S2 store different types of detergents respectively; for example, the first accommodating chamber S1 and the second accommodating chamber S2 store laundry liquid and softener respectively; the first accommodating chamber S1 and the second accommodating chamber S2 store laundry liquid and disinfectant respectively; the first accommodating chamber S1 and the second accommodating chamber S2 store softener and disinfectant respectively.

[0055] In the embodiment, the pump 140 delivers different detergents to the foamer 110 through the first interface 113 and the third interface 114 respectively, so as to complete the work of adding different detergents.

[0056] In some embodiments, the detergent box 130 may also be provided with a third storage chamber, and the pump 140 is configured to pump different detergents in the first storage chamber S1, the second storage chamber S2, and the third storage chamber into the foamer 110 for mixing. For example, the first storage chamber S1, the second storage chamber S2, and the third storage chamber store laundry detergent, softener, and disinfectant, respectively.

[0057] As an optional implementation of the above embodiment, the pump 140 is a peristaltic pump 140, such as Figure 4As shown, the peristaltic pump 140 has a first peristaltic channel 141 and a second peristaltic channel 142; the first peristaltic channel 141 communicates with the first accommodating chamber S1 and the foamer 110, and the second peristaltic channel 142 communicates with the second accommodating chamber S2 and the foamer 110. In an embodiment, the detergent box 130 is provided with a first liquid outlet communicated with the first accommodating chamber S1 and a second liquid outlet communicated with the second accommodating chamber S2. The first extraction column on the first peristaltic channel 141 is sealed with the first liquid outlet to extract laundry liquid from the first accommodating chamber S1 when the peristaltic pump 140 is started; the second extraction column on the second peristaltic channel 142 is sealed with the second liquid outlet to extract softener from the second accommodating chamber S2 when the peristaltic pump 140 is started.

[0058] In an embodiment, in combination Figure 4 , Figure 6 and Figure 7 As shown, a first conduit 161 is provided at the first interface 113, and a second conduit 162 is provided at the second interface 115. The first drainage column 1411 of the first peristaltic channel 141 is sealed and connected with the first conduit 161 to discharge the first type of detergent into the foamer 110; the second drainage column 1421 of the second peristaltic channel 142 is sealed and connected with the second conduit 162 to discharge the second type of detergent into the foamer 110.

[0059] As an optional implementation of the above embodiment, Figure 7 As shown, the first interface 113 and the third interface 114 are arranged at intervals in the water flow direction and both face the detergent box 130. In the embodiment, the first interface 113 and the third interface 114 are arranged toward the detergent box 130, so that the pump 140 can lead the injection pipeline into the foamer 110 from the same direction.

[0060] For example, the pump 140 is a peristaltic pump 140 , and the first injection column and the second injection column of the peristaltic pump 140 can be connected to the first interface 113 and the second interface 115 respectively from the same direction, thereby facilitating the layout of the peristaltic pump 140 .

[0061] In an embodiment, the peristaltic pump 140 is disposed on one side of the detergent box 130 , and the first injection column and the second injection column of the peristaltic pump 140 are disposed on the same side, thereby reducing the space occupied by the peristaltic pump 140 and improving the space utilization of the washing device 10 .

[0062] As an optional implementation of the above embodiment, Figure 5 , Figure 6 and Figure 7As shown, the foamer 110 includes a housing 111 and a foaming component 112 disposed in the housing 111; the foaming component 112 includes a foaming body 1121 and foaming fins 1122 disposed on the foaming body 1121. The foamer 110 is provided with a foaming body 1121, and the foaming body 1121 is provided with a plurality of foaming fins 1122. In an embodiment, a mixture of water and detergent flows into the foamer 110 through a third pipe; the mixture of water and detergent dissolves the detergent in advance and forms foam under the action of the foaming fins 1122, which can improve the dissolution efficiency and uniformity of the detergent, reduce the rotation time of the washing inner drum, and improve the washing efficiency and the cleanliness of the laundry.

[0063] The foaming body 1121 may be a closed loop structure or a non-closed loop structure, such as a C-shaped structure, a V-shaped structure, etc. When water flows through the foaming body 1121 and carries detergent, it interacts with the foaming fins 1122 on the foaming body 1121 to generate bubbles.

[0064] like Figure 6 and Figure 7 As shown, the foamer 110 includes a housing 111, and the housing 111 is provided with a first interface 113 and a second interface 115. The first interface 113 is provided at the side of the housing 111, and the second interface 115 is provided at the end of the housing 111. In the direction of the water flow, a foaming component 112 is provided between the first interface 113 and the second interface 115; after the washing water enters the foamer 110, before it is mixed with the detergent, the washing water is disturbed under the action of the foaming fins 1122, generating vortices and air bubbles; these generated vortices and air bubbles are mixed with the detergent during the flow, and the detergent is fully broken up and foamed, so that the detergent is dissolved. In the embodiment, the foamer 110 is further provided with a foaming component 112 at the rear side of the first interface 113 in the direction of the water flow, and the detergent dissolved in the vortex and air bubbles is formed into a foam under the action of the foaming fins 1122, which improves the dissolution efficiency and uniformity of the detergent, and can also improve the cleanliness while reducing the rotation of the washing inner drum.

[0065] like Figure 6 and Figure 7As shown, in some embodiments, the housing 111 is further provided with a third interface 114. The third interface 114 is provided on the side of the outside and is spaced apart from the first interface 113. In an embodiment, the third interface 114 is located in the downstream area of ​​the first interface 113. A foaming component 112 is provided between the third interface 114 and the first interface 113. After the first type of detergent and the washing water are bubbled, bubbles and vortices will be generated. When the bubbles and vortices meet the second type of detergent, the second type of detergent will be fully broken up and foamed, so that the second type of detergent is fully dissolved in the mixture of the first type of detergent and the washing water. The foamer 110 is further provided with a foaming component 112 at the rear side of the third interface 114 in the direction of water flow. The first and second types of detergents dissolved in the vortex and air bubbles are formed into foam under the action of the foaming fins 1122, so that the two different detergents are fully mixed, the dissolution efficiency of the detergent and the uniformity of the detergent are improved, and the degree of cleanliness can be improved while reducing the rotation of the washing inner drum.

[0066] As an optional implementation of the above embodiment, Figure 8 and Fig. 9 As shown, the foaming body 1121 has an extension direction; the foaming body 1121 has a plurality of cross sections 1121a, the normal direction of the cross section 1121a is the extension direction; the normal direction of the cross section 1121a is set at an angle with the water flow direction; each cross section 1121a is provided with a plurality of foaming fins 1122 arranged at intervals along the circumference of the cross section 1121a. The extension direction of the foaming body 1121 is the tangent direction of a certain circle, and the cross section 1121a of the foaming body 1121 is circular; the space occupied by the cross section 1121a moving one circle along the circumferential direction is the space occupied by the foaming body 1121. The normal direction of the cross section 1121a is the extension direction, which can be understood as: the normal direction of the cross section 1121a is perpendicular to the tangent direction of the circle in which the foaming body 1121 moves. A plurality of foaming fins 1122 are provided at the section 1121a of the foaming body 1121 at circumferential intervals along the section 1121a. When water carries detergent, the foaming fins 1122 can fully disturb the water flow, causing a slight relative movement between the water and the detergent to generate bubbles.

[0067] In some embodiments, the normal direction of the cross section 1121a is set at an angle to the water flow direction, thereby enhancing the disturbance intensity of the foaming fins 1122 on water and detergent and improving the solubility of the detergent. For example, the normal direction of the cross section 1121a is perpendicular to the water flow direction.

[0068] As an optional implementation of the above embodiment, Figure 7As shown, as an optional embodiment of the above embodiment, the foaming components 112 are provided in plurality, and the plurality of foaming components 112 are sequentially spaced apart along the water flow direction. In the embodiment, three foaming components 112 are provided in the foamer 110, and a plurality of foaming fins 1122 are provided on a foaming body 1121 of each foaming component 112; by providing a plurality of foaming bodies 1121 spaced apart along the water flow direction, the detergent is effectively dissolved and foamed.

[0069] In an embodiment, two or more foaming bodies 1121 may be provided.

[0070] In the embodiment, the spacing between the foaming bodies 1121 can be equidistant. The spacing between the foamers 110 can also be non-equidistant. For example, the spacing between the foaming bodies 1121 gradually decreases along the water flow direction, and the foaming bodies 1121 that the water flow encounters first play a role in dissolving the detergent in the water, while the foaming bodies 1121 that follow mainly play a role in foaming.

[0071] As an optional implementation of the above embodiment, a floating ring (not shown) and a detection structure (not shown) are provided in the detergent box 130; the detection structure is configured to generate a prompt signal when the floating ring enters the detection range of the detection structure, so as to prompt the user to put detergent into the detergent box 130. In some embodiments, a first floating ring positioning column is designed inside the first accommodating chamber S1, and a first floating ring is installed on the first floating ring positioning column. The first floating ring will float as the detergent in the detergent accommodating chamber increases or decreases. The first magnetic detection mechanism is installed below the first floating ring. When the laundry detergent in the first accommodating chamber S1 decreases and falls into the detection range of the first magnetic detection mechanism as the user uses it, the first magnetic detection mechanism detects the magnetic signal and transmits it to the washing machine control system to feedback a prompt signal for adding laundry detergent. A second floating ring positioning column is designed inside the second accommodating chamber S2, and a second floating ring is installed on the second floating ring positioning column. The floating ring will float as the detergent in the detergent accommodating chamber increases or decreases. The second magnetic detection mechanism is installed below the second floating ring. When the second accommodating chamber S2 decreases and falls within the detection range of the second magnetic detection mechanism as the user uses it, the second magnetic detection mechanism detects the magnetic signal and transmits it to the washing machine control system to feedback a prompt signal for adding softener.

[0072] In the technical solution of the embodiment of the present application, the detergent box 130 can be designed to be transparent and visible to indicate the internal liquid level, and can be provided with a scale display to intuitively show the internal solution level.

[0078] The control panel 210 is provided with a mounting notch, and the liquid inlet is located in the mounting notch. In the embodiment, the liquid inlet is located in the mounting notch. A sealing cover 230 is threadedly matched on the liquid inlet.

[0079] The washing device further comprises a flap 220, which is rotatably connected to the installation gap and is used to open or close the installation gap. In an embodiment, by opening the flap 220, the liquid inlet can be exposed to facilitate the filling of laundry detergent or softener.
