[0065] Background

[0066] Detergent foam can play a good role in cleaning and softening clothes during the washing process. Currently, existing washing machines usually do not have an active foam generating device, and foam can only be generated after washing for a period of time. The detergent takes a long time to take effect, and some detergents cannot be completely dissolved in water, affecting the cleaning effect.

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

[0068] Foam generating box 100;

[0069] A foaming module 200, the foaming module 200 is arranged in the foam generating box 100, and a foam generating chamber 300 is defined between the foaming module 200 and the foam generating box 100, the foam generating box 100 has a liquid inlet 101, an air inlet 102 and a bubble discharge port 103, the liquid inlet 101 is used to inject detergent water mixed with detergent and washing water into the foam generating chamber 300, the air inlet 102 is used to pass gas into the foaming module 200, so as to use the foaming module 200 to foam the detergent water passed into the foam generating chamber 300, and the bubble discharge port 103 is used to discharge the foam generated in the foam generating chamber 300;

[0070] The nozzle 400 is disposed in the foam generating box 100, one end of the nozzle 400 is connected to the liquid inlet 101, and the other end is disposed corresponding to the bubble outlet 103;

[0071] An air suction channel 500 connecting the bubble discharge port 103 and the foam generating chamber 300 is defined between the corresponding ends of the nozzle 400 and the bubble discharge port 103, so that when the nozzle 400 sprays detergent water outward, the foam generated in the foam generating chamber 300 can be sucked into the air suction channel 500 through the action of negative pressure, and discharged from the bubble discharge port 103 together with the detergent water sprayed by the nozzle 400.

[0072] In the embodiment of the present application, a foaming module 200 and a nozzle 400 are arranged in the foam generating box 100. The foaming module 200 can foam the detergent water in the foam generator 10. The nozzle 400 can discharge the detergent entering the foam generator 10 into the fabric processing device on the one hand, and on the other hand, the outlet end of the nozzle 400 corresponds to the bubble discharge port of the foam generator 10. When the nozzle 400 sprays detergent water outward, it can generate negative pressure at the position of the suction channel 500 between the nozzle 400 and the bubble discharge port 103 due to the high-speed jet water flow at the outlet, and use the negative pressure to suck the foam generated in the foam generating chamber 300 into the suction channel 500, and discharge it from the bubble discharge port 103 together with the detergent water sprayed by the nozzle 400, thereby achieving the effect of mixing the jet water with the prepared foam, thereby increasing the discharge speed of the foam, so that the discharged foam can cover the surface of the clothes in the fabric processing device.

[0073] Further, in some possible implementations, the nozzle 400 includes a first pipe section 4011 and a second pipe section 4012 which are connected in sequence, the inlet of the first pipe section 4011 is connected to the liquid inlet 101, and the outlet is connected to the second pipe section 4012, the inlet of the second pipe section 4012 is connected to the outlet of the first pipe section 4011, and the outlet is arranged corresponding to the bubble discharge port 103;

[0074] The second pipe section 4012 corresponding to the bubble discharge port 103 is constructed as a tapered pipe section from the inlet side of the second pipe section 4012 to the outlet side of the second pipe section 4012 .

[0075] In the embodiment of the present application, the second pipe section 4012 is constructed as a tapered pipe section. This design helps to increase the fluid velocity, allowing the detergent water to flow faster when passing through the nozzle 400, thereby generating a stronger spray force and negative pressure at the outlet, which helps to adsorb, mix and discharge the foam.

[0076] Further, in some possible implementations, the bubble outlet 103 is configured to be tapered from the inlet side of the bubble outlet 103 to the outlet side of the bubble outlet 103;

[0077] At least a portion of the second tube section 4012 of the tapered structure is embedded in the bubble discharge port 103 of the tapered structure, so that an annular conical air intake channel 500 is defined between the second tube section 4012 and the bubble discharge port 103 .

[0078] In the embodiment of the present application, the second pipe section 4012 of the tapered structure is embedded in the bubble discharge port 103 of the tapered structure, and forms a ring-conical air intake channel 500. This design can enhance the negative pressure effect of the air intake channel, and more effectively suck the foam into the channel and discharge it. At the same time, since the second pipe section 4012 of the tapered structure is embedded in the bubble discharge port 103 of the tapered structure, it can also make the channel cross-sectional area of ​​the air intake channel 400 smaller than the cross-sectional area of ​​the bubble discharge port 103 and the foam generating chamber 300, so that when the large-diameter foam in the foam generating chamber 300 is sucked into the air intake channel 500, the large-diameter foam can be squeezed and broken into small-diameter foam due to the surface of the channel cross-sectional area, thereby increasing the number of foams while making the foams more delicate, thereby improving the washing effect on clothes.

[0079] Furthermore, in some possible implementations, the liquid inlet 101 and the bubble outlet 103 of the foam generating box 100 are arranged correspondingly, and the nozzle 400 is a straight pipe section arranged between the liquid inlet 101 and the bubble outlet 103 .

[0080] The straight nozzle 400 design of the embodiment of the present application reduces the path length and complexity of the fluid flow, helps to increase the flow speed of the detergent water, thereby enabling a greater negative pressure to be generated at the air intake channel 500 at the bubble discharge port 103, thereby effectively sucking the foam in the foam generating chamber 300 into the air intake channel 500 and mixing it with the jet water ejected from the nozzle 400.

[0081] Further, in some possible implementations, the nozzle 400 includes a main pipe section 401 and a bypass pipe section 402 connected to the main pipe section 402;

[0082] The inlet of the main pipe section 401 is connected to the liquid inlet 101, and the outlet corresponds to the bubble outlet 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 chamber 300, so that a part of the detergent water entering into the nozzle 400 from the liquid inlet 101 can be sprayed out through the nozzle 400, and the other part can enter the foam generating chamber 300 for foaming.

[0083] In the embodiment of the present application, through the design of the main pipe section 401 and the bypass pipe section 402, the detergent water can be split after entering the nozzle 400 from the liquid inlet 101, with one part being directly sprayed out and the other part entering the foam generating chamber 300 for foaming. This split flow 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 may be eliminated, and a separate pipeline may be provided to allow detergent water to enter the foam generating chamber 300 for foaming.

[0085] But relatively speaking, it is preferred that a bypass pipeline is provided on one pipeline, which occupies less space and improves the utilization rate of detergent water and the working efficiency of the foam generator.

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

[0087] Further, in some possible implementations, the foam generating box 100 is configured as a rectangle, and the foaming module 200 includes an aeration head of a rectangular configuration;

[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 colinear with the central axis of the foam generating box, which helps to achieve uniform generation of foam in the foam generating chamber, because the gas can be evenly distributed from the center to the surroundings, thereby improving the uniformity and quality of the foam.

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

[0091] A clamping structure is formed on the liquid inlet 101 and the bubble discharge port 103 , and the liquid inlet 101 and the bubble discharge port 103 can be detachably connected to the corresponding liquid inlet pipe 800 and the bubble discharge pipe 900 through the clamping structure.

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

[0093] Further, in some possible implementations, the detergent dispensing assembly 600 includes a detergent box having an opening at the top, and the foam generator 10 is disposed at the opening of the detergent box and serves as a box cover of the detergent box to seal the detergent box.

[0094] Furthermore, the third aspect of the embodiment of the present application also provides a fabric processing device, which includes the detergent dispensing component 600 provided in the second aspect of the embodiment of the present application.

[0095] Further, in some possible implementations, the fabric processing device includes:

[0096] A liquid inlet pipeline 800 is provided between the fabric treatment drum 700, the detergent delivery assembly 600 and the foam generator 10, and the liquid inlet pipeline 800 is used to deliver detergent water mixed with detergent and washing water into the foam generating chamber 300 in the foam generator 100. A bubble delivery pipe 900 is provided between the foam generator 10 and the fabric treatment drum 700, and the bubble delivery pipe 900 is used to deliver the foam generated in the foam generator 10 into the fabric treatment drum 700.

[0097] Further, in some possible implementations, the fabric processing device further includes:

[0098] The ozone generating device 20 is communicated with the foam generator 10 and / or the liquid inlet pipeline 800 so that the ozone gas generated by the ozone generating device 20 can adhere to the foam generated by the foam generator 10 .

[0099] In the embodiment of the present application, the ozone generator is connected to the foam generator so that the ozone gas can be directly attached to the foam, and the strong oxidizing property of ozone is utilized to improve the sterilization effect of the fabric treatment equipment. Ozone gas can decompose the active ingredients in the detergent, making it more effective in removing stains, thereby improving the cleaning effect. The oxidizing effect of ozone helps prevent the mixing and fading of clothing colors, while the disinfecting effect of ozone also helps to soften clothing and reduce damage to clothing during the washing process. In the embodiment of the present application, the introduction of ozone gas can change the physical properties of the foam, which may make the foam more delicate and stable, thereby improving the washing effect of the foam.

[0100] Further, in some possible implementations, the ozone generating device 20 includes an ozone generator 201, an air pump 202, and an air pipe 203, and the ozone generator 201 is connected to the foaming module 200 of the foam generator 10 through the air pipe 203;

[0101] An air intake check valve 204 is disposed on the air pipe 203 , and the air intake check valve 204 is designed to allow fluid to flow out of the ozone generator 201 and restrict the fluid from flowing back to the ozone generator 201 .

[0102] In the embodiment 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 of ozone, ensuring that the foam in the foam generator 10 can be evenly covered with ozone gas. The design of the air inlet check valve 204 allows gas to flow from the ozone generator 201 to the foam generator 10 while preventing gas from flowing back, which helps prevent the internal pressure of the ozone generator 201 from being too high and ensures the safe operation of the equipment. The use of the check valve ensures that ozone gas will not be wasted, and all the ozone generated can be effectively used for the generation and treatment of foam, thereby improving the utilization efficiency of ozone.

[0103] Furthermore, in some possible implementations, the detergent dispensing component 600 further includes:

[0104] At least one storage chamber 601 for storing detergent and / or softener, and a detergent dissolving chamber 603 connected to the storage chamber 601 via a dosing pump 602;

[0105] The amount of detergent and / or softener pumped from the storage chamber 601 into the detergent dissolving chamber 603 can be controlled by controlling the operation of the dosing pump 602 . The detergent dissolving chamber 603 is connected to the foam generator 10 via the liquid inlet line 800 .

[0106] In the embodiment of the present application, by mixing the detergent and washing water in the detergent dissolving chamber and then delivering them to the foam generator for foaming, it is possible to ensure that the detergent is fully dissolved and dispersed in the water, thereby improving the washing efficiency and cleaning effect. Furthermore, in the embodiment of the present application, by controlling the operation of the delivery pump, the amount of detergent and / or softener pumped from the storage chamber into the detergent dissolving chamber can be accurately controlled, thereby improving the washing effect and clothing care quality. At the same time, since the detergent and / or softener are pumped into the detergent dissolving chamber by the delivery pump, the pressure of the detergent and / or softener when entering the detergent dissolving chamber can also be increased, so that the detergent and / or softener can be fully mixed with the washing water entering the detergent dissolving chamber through the water inlet pipe to form detergent water, so as to improve the foaming effect of the subsequent foam generating device on the detergent water.

[0107] Further, in some possible implementations, the fabric processing device further includes a water inlet pipeline 30, and the water inlet pipeline 30 includes:

[0108] A first water inlet pipeline 301, the first water inlet pipeline 301 is used to inject washing water into the detergent dissolving chamber 603;

[0109] A second water inlet pipe 302, the second water inlet pipe 302 is used to spray washing water to the window pad fold position of the fabric treatment drum 700;

[0110] A third water inlet pipeline 303, the third water inlet pipeline 303 is used to inject washing water into the fabric treatment drum 700;

[0111] in

[0112] The first water inlet pipeline 301, the second water inlet pipeline 302 and the third water inlet pipeline 303 are each individually 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 a water inlet valve.

[0115] In the embodiment of the present application, each water inlet pipeline is independently provided with a water inlet valve, which can accurately control the water flow of each pipeline to ensure that the water flow requirements of each part during the washing process are met. It is worth noting that when considering the setting 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}.
