[0065] BACKGROUND

[0066] Detergent foam can play a good cleaning and soft protection role in the laundry process.Currently, the existing washing machine usually does not have an active foam generator, and foam can be generated only after a period of washing, the detergent develops slowly, and part of the detergent cannot be completely dissolved in water, which affects the cleaning effect.

[0067] Based on this, as shown in Figure 1 and Figure 2 , the first aspect of the embodiment of the application provides a foam generator, the foam generator 10 comprises:

[0068] a foam generating box 100;

[0069] a foaming module 200, the foaming module 200 is arranged in the foam generating box 100, and the foaming module 200 and the foam generating box 100 define a foam generating cavity 300, the foam generating box 100 has a liquid inlet 101, an air inlet 102 and a foam outlet 103, the liquid inlet 101 is used for injecting detergent water mixed with detergent and washing water into the foam generating cavity 300, the air inlet 102 is used for introducing gas into the foaming module 200, so that the foaming module 200 is used for foaming the detergent water introduced into the foam generating cavity 300, and the foam outlet 103 is used for discharging the generated foam in the foam generating cavity 300;

[0070] a spray pipe 400, the spray pipe 400 is arranged in the foam generating box 100, one end of the spray pipe 400 is communicated with the liquid inlet 101, and the other end of the spray pipe 400 is arranged corresponding to the foam outlet 103;

[0071] wherein the end of the spray pipe 400 corresponding to the foam outlet 103 and the foam outlet 103 define an air suction channel 500 communicating the foam outlet 103 and the foam generating cavity 300, so that the foam generated in the foam generating cavity 300 can be sucked into the air suction channel 500 through the action of negative pressure when the spray pipe 400 sprays the detergent water outward, and discharged from the foam outlet 103 together with the detergent water sprayed by the spray pipe 400.

[0072] In the embodiments of the present application, the foaming module 200 and the spray pipe 400 are arranged in the foam generator 10. The detergent water in the foam generator 10 can be foamed by the foaming module 200. The spray pipe 400 can discharge the detergent water into the fabric treatment device. The outlet of the spray pipe 400 corresponds to the foam discharge port of the foam generator 10. When the spray pipe 400 sprays the detergent water, the high-speed water flow at the outlet can generate negative pressure in the air suction channel 500 between the spray pipe 400 and the foam discharge port 103. The negative pressure can suck the foam in the foam generating cavity 300 into the air suction channel 500, and the foam and the detergent water sprayed by the spray pipe 400 are discharged from the foam discharge port 103. Thus, the jet water and the prepared foam can be mixed and discharged, the discharge speed of the foam is improved, and the discharged foam can cover the surface of the clothes in the fabric treatment device.

[0073] Further, in some possible embodiments, the spray pipe 400 includes a first pipe segment 4011 and a second pipe segment 4012 which are sequentially communicated. The inlet of the first pipe segment 4011 is communicated with the liquid inlet 101, and the outlet of the first pipe segment 4011 is communicated with the second pipe segment 4012. The inlet of the second pipe segment 4012 is communicated with the outlet of the first pipe segment 4011, and the outlet of the second pipe segment 4012 is arranged corresponding to the foam discharge port 103.

[0074] The second pipe segment 4012 arranged corresponding to the foam discharge port 103 is tapered from the inlet side of the second pipe segment 4012 to the outlet side of the second pipe segment 4012.

[0075] In the embodiments of the present application, the second pipe segment 4012 is tapered. This design can increase the fluid speed, so that the detergent water can flow faster when passing through the spray pipe 400, thereby generating stronger jet force and negative pressure at the outlet, which is helpful for the adsorption, mixing and discharge of the foam.

[0076] Further, in some possible embodiments, the foam discharge port 103 is tapered from the inlet side of the foam discharge port 103 to the outlet side of the foam discharge port 103.

[0077] The second pipe segment 4012 arranged corresponding to the foam discharge port 103 is tapered from the inlet side of the second pipe segment 4012 to the outlet side of the second pipe segment 4012.

[0078] The second pipe section 4012 in the tapering structure in the embodiments of the present application is embedded in the tapering structure of the bubble discharge port 103, and forms a ring-tapered air suction channel 500. This design can enhance the negative pressure effect of the air suction channel, and more effectively suck the foam into the channel and discharge it. At the same time, since the second pipe section 4012 in the tapering structure is embedded in the tapering structure of the bubble discharge port 103, the channel cross-sectional area of the air suction channel 500 is smaller than the cross-sectional area of the bubble discharge port 103 and the foam generating cavity 300, so that when the large-diameter foam in the foam generating cavity 300 is sucked into the air suction channel 500, the large-diameter foam can be crushed and broken into small-diameter foam due to the surface of the channel cross-sectional area, thereby increasing the number of foam and making the foam more delicate, thereby improving the washing effect on clothes.

[0079] Further, in some possible embodiments, the liquid inlet 101 and the bubble discharge port 103 of the foam generating box 100 are correspondingly arranged, and the spray pipe 400 is a straight pipe section arranged between the liquid inlet 101 and the bubble discharge port 103.

[0080] The straight spray pipe 400 in the embodiments of the present application reduces the path length and complexity of fluid flow, which helps to improve the flow speed of the detergent water, so that a greater negative pressure can be generated at the air suction channel 500 at the position of the bubble discharge port 103, thereby effectively sucking the foam in the foam generating cavity 300 into the air suction channel 500 and mixing with the jet water sprayed by the nozzle 400.

[0081] Further, in some possible embodiments, the spray pipe 400 includes a main pipe section 401 and a bypass pipe section 402 connected to the main pipe section 401.

[0082] The inlet of the main pipe section 401 is connected to the liquid inlet 101, and the outlet corresponds to the bubble discharge port 103. The inlet of the bypass pipe section 402 is connected to the main pipe section 401, and the outlet is connected to the foam generating cavity 300, so that the detergent water entering the spray pipe 400 from the liquid inlet 101 can be sprayed out through the spray pipe 400, or enter the foam generating cavity 300 for foaming.

[0083] In the embodiments of the present application, through the design of the main pipe section 401 and the bypass pipe section 402, the detergent water can be divided into two parts after entering the spray pipe 400 from the liquid inlet 101, one part is directly sprayed out, and the other part enters the foam generating cavity 300 for foaming. This split design improves the utilization rate of the detergent water and the working efficiency of the foam generator.

[0084] Of course, in some alternative embodiments, the bypass pipe can be cancelled, and a separate pipe can be arranged to make the detergent water enter the foam generating cavity 300 for foaming.

[0085] But relatively, preferably, by setting a bypass pipeline on a pipeline, the design occupies less space, and the utilization rate of detergent water and the working efficiency of the foam generator are higher.

[0086] Further, in some possible embodiments, the foam generating box 100 includes a flat box body and a box cover, and the box body and the box cover are tightly sealed by being pressed together and locked by a locking structure. Preferably, the two are assembled and sealed by hot plate welding, adhesive bonding, screw fastening, or the like.

[0087] Further, in some possible embodiments, the foam generating box 100 is configured in a rectangular shape, and the foaming module 200 includes an aeration head configured in a rectangular shape.

[0088] The central axis of the aeration head arranged in the foam generating box 100 is collinear with the central axis of the foam generating box 100.

[0089] In the embodiment of the present application, the central axis of the aeration head is collinear with the central axis of the foam generating box, which helps to realize uniform generation of foam in the foam generating cavity, because the gas can be uniformly distributed from the center to the periphery, thereby improving the uniformity and quality of the foam.

[0090] Further, in some possible embodiments, the foam generating box 100 is integrally formed with a liquid inlet 101 and a foam outlet 103 on both sides of the water inlet direction of the foam generating box 100.

[0091] The liquid inlet 101 and the foam outlet 103 are formed with clamping structures, and the liquid inlet 101 and the foam outlet 103 can be detachably connected to the corresponding liquid inlet pipeline 800 and the foam outlet pipeline 900 through the clamping structures.

[0092] Further, the second aspect of the embodiment of the present application further provides a detergent dispensing assembly, which includes the foam generator 10 provided by the first aspect of the embodiment of the present application.

[0093] Further, in some possible embodiments, the detergent dispensing assembly 600 includes a detergent box with an opening at the top, and the foam generator 10 is arranged at the opening of the detergent box and seals the detergent box as a box cover of the detergent box.

[0094] Further, the third aspect of the embodiment of the present application further provides a fabric treatment apparatus, which includes the detergent dispensing assembly 600 provided by the second aspect of the embodiment of the present application.

[0095] Further, in some possible embodiments, the fabric treatment apparatus includes:

[0096] The fabric treatment drum 700, the detergent dispensing assembly 600 and the foam generator 10 are provided with a liquid inlet pipeline 800 for dispensing the detergent water mixed with the detergent and washing water into the foam generation cavity 300 in the foam generator 10. The foam generator 10 and the fabric treatment drum 700 are provided with a foam delivery pipeline 900 for dispensing the foam generated in the foam generator 10 into the fabric treatment drum 700.

[0097] Further, in some possible embodiments, the fabric treatment apparatus further comprises:

[0098] The ozone generation device 20 is in communication with the foam generator 10 and / or the liquid inlet pipeline 800, so that the ozone gas generated by the ozone generation device 20 can be attached to the foam generated by the foam generator 10.

[0099] In the embodiments of the present application, the ozone generation device is in communication with the foam generator, so that the ozone gas can be directly attached to the foam, the strong oxidizing property of ozone is utilized, and the sterilization effect of the fabric treatment apparatus is improved. The ozone gas can decompose the active ingredients in the detergent, so that the detergent can more effectively remove stains and thus improve the cleaning effect. The oxidation of ozone helps to prevent the mixing and fading of the color of clothes, and the sterilization of ozone also helps to protect the clothes and reduce the damage to the clothes in the washing process. In the embodiments of the present application, the introduction of ozone gas can change the physical properties of the foam, so that the foam can be more delicate and stable, and thus the washing effect of the foam is improved.

[0100] Further, in some possible embodiments, the ozone generation device 20 comprises an ozone generator 201, an air pump 202 and an air pipe 203, the ozone generator 201 is in communication with the foaming module 200 of the foam generator 10 through the air pipe 203;

[0101] The air pipe 203 is provided with an air inlet one-way valve 204, which is designed to allow fluid to flow out of the ozone generator 201 and limit fluid to flow back to the ozone generator 201.

[0102] In the embodiments of the present application, the combination of the ozone generator 201, the air pump 202 and the air pipe 203 can accurately control the generation and supply amount of ozone, and ensure that the foam in the foam generator 10 can be uniformly covered by the ozone gas. The design of the air inlet one-way valve 204 allows the gas to flow from the ozone generator 201 to the foam generator 10, while preventing backflow, which helps to prevent the internal pressure of the ozone generator 201 from being too high and ensures the safe operation of the apparatus. The use of the one-way valve ensures that the ozone gas will not be wasted, and all the generated ozone can be effectively used for the generation and treatment of the foam, and the utilization efficiency of the ozone is improved.

[0103] Further, in some possible embodiments, the detergent dispensing assembly 600 further comprises:

[0104] at least one storage cavity 601 for storing detergent and / or softener, and a detergent dissolving cavity 603 in communication with the storage cavity 601 through a dispensing pump 602;

[0105] wherein the amount of detergent and / or softener pumped from the storage cavity 601 into the detergent dissolving cavity 603 can be controlled by controlling the operation of the dispensing pump 602, and the detergent dissolving cavity 603 is in communication with the foam generator 10 through the water inlet pipeline 800.

[0106] In the embodiments of the present application, the detergent and washing water are mixed in the detergent dissolving cavity and then delivered to the foam generator for foaming, which can ensure that the detergent is fully dissolved and dispersed in water, thereby improving the washing efficiency and cleaning effect. Further, in the embodiments of the present application, the amount of detergent and / or softener pumped from the storage cavity 601 into the detergent dissolving cavity 603 can be accurately controlled by controlling the operation of the dispensing pump 602, thereby improving the washing effect and the quality of clothes care. At the same time, since the detergent and / or softener are pumped into the detergent dissolving cavity by the dispensing pump, the pressure of the detergent and / or softener when entering the detergent dissolving cavity can also be improved, so that the detergent and / or softener can be fully mixed with the washing water entering the detergent dissolving cavity through the water inlet pipeline to form detergent water, thereby improving the foaming effect of the subsequent foam generating device on the detergent water.

[0107] Further, in some possible embodiments, the fabric treatment apparatus further comprises a water inlet pipeline 30, and the water inlet pipeline 30 comprises:

[0108] a first water inlet pipeline 301 for injecting washing water into the detergent dissolving cavity 603;

[0109] a second water inlet pipeline 302 for spraying washing water to the window gasket wrinkle position of the fabric treatment drum 700;

[0110] a third water inlet pipeline 303 for injecting washing water into the fabric treatment drum 700;

[0111] wherein

[0112] the first water inlet pipeline 301, the second water inlet pipeline 302 and the third water inlet pipeline 303 are each separately provided with a water inlet valve;

[0113] or

[0114] at least two of the first water inlet pipeline 301, the second water inlet pipeline 302 and the third water inlet pipeline 303 share one water inlet valve.

[0115] In the embodiments of the present application, each water inlet pipeline is independently provided with a water inlet valve, so that the water flow of each pipeline can be accurately controlled to ensure that the water flow requirements of each part during the washing process are met. It should be noted that, when considering the arrangement of the water inlet pipeline from the perspective of saving cost and installation space, at least two water inlet pipelines can share one water inlet valve (not shown in the figure).

[0116] Preferably, the third water inlet pipeline 303 described above is connected with the manual dispensing device, and is used for manually dispensing the detergent.

[0117] Further, in some possible embodiments, the fabric treatment drum 700 comprises an outer drum and an inner drum pivotably arranged in the outer drum, and the fabric treatment apparatus is a drum-type fabric treatment apparatus with the outer drum and the inner drum.
