[0068] Background

[0069] Detergent foam can play a good cleaning and soft protection role in the laundry process. At present, the existing washing machines usually do not have an active foam generating device, and foam can be generated only after a period of washing, the effect of the detergent is slow, and part of the detergent cannot be completely dissolved in water, affecting the cleaning effect.

[0070] Based on this, as Figures 1-4 shown in the first aspect of the embodiments of the present application provides a foam generator for fabric treatment equipment, the foam generator 10 comprises:

[0071] The shell is internally formed with a foam generating cavity 100, and the foam generating cavity is provided with a liquid inlet 101 for introducing detergent water mixed with detergent and washing water into the foam generating cavity 100.

[0072] The foaming module 200 is arranged in the foam generating cavity 100 and is used for foaming treatment of the detergent water introduced into the foam generating cavity 100.

[0073] The nozzle 300 is communicated with the foam generating cavity 100 and is used for discharging the foam generated in the foam generating cavity 100, and the nozzle 300 comprises a jet section.

[0074] The caliber of the jet section is designed to be a variable caliber from the inlet direction to the outlet direction, so that the large-diameter foam entering the jet section can be broken into small-diameter foam due to the change of the caliber of the jet section.

[0075] In the embodiments of the present application, the nozzle communicated with the foam generating cavity is arranged, and the caliber of the jet section of the nozzle is designed to be a variable caliber from the inlet direction to the outlet direction, so that the large-diameter foam entering the jet section can be broken into small-diameter foam due to the change of the caliber of the jet section, so that the foam can be fully mixed with the washing water. It should be noted that the variable caliber nozzle design not only can produce finer foam, but also can optimize the yield of foam by controlling the breaking degree of foam, so that the foam generator can produce appropriate high-quality foam, which not only meets the washing demand, but also does not cause resource waste.

[0076] Further, in some possible embodiments, the jet section comprises a tapered jet section 300a and a diverging jet section 300c arranged in sequence and communicated with each other from the inlet direction to the outlet direction.

[0077] The tapered jet section 300a is used for pressurizing the foam flowing therethrough, and the diverging jet section 300c is used for depressurizing the foam flowing therethrough.

[0078] The tapered injection section 300a in the embodiments of the present application is used to pressurize the foam flowing therethrough, which helps to increase the density and stability of the foam, so that the foam can better carry the detergent and the sterilization ingredients, and improve the washing and sterilization effects. The divergent injection section 300c is used to depressurize the foam flowing therethrough, which helps to release and disperse the foam, so that the foam can have enough flow space to flow into the fabric treatment device, the flowability of the foam is improved, so that the foam is more easily covered on the surface of the clothes in the fabric treatment drum, which helps to improve the washing efficiency.

[0079] Further, in some possible implementations, the injection section further comprises a jet section 300b communicated between the narrow end of the tapered injection section 300a and the narrow end of the divergent injection section 300c, the jet section 300b being a thin straight pipe section;

[0080] wherein the caliber of the jet section 300b is less than or equal to the caliber of the narrow end of the tapered injection section 300a; or the caliber of the jet section 300b is less than or equal to the caliber of the narrow end of the divergent injection section 300c, so as to increase the speed of the foam flowing from the tapered injection section 300a to the divergent injection section 300c.

[0081] The jet section 300b in the embodiments of the present application is a thin straight pipe section, and the caliber thereof is less than or equal to the caliber of the narrow end of the tapered injection section 300a or the caliber of the narrow end of the divergent injection section 300c. Such a design can increase the speed of the foam flowing through the jet section 300b, thereby improving the flowability and impact force of the foam. Since the caliber of the jet section 300b is small, the foam will be subjected to further shearing force when passing through, which helps to mix and refine the foam, so that the foam is more uniform and delicate, thereby improving the washing effect. The design of the jet section 300b makes the foam experience an increase in speed during the process of flowing from the tapered injection section 300a to the divergent injection section 300c, which helps to control the breaking and formation of the foam during the transition from the high-pressure zone to the low-pressure zone, thereby optimizing the stability and uniformity of the foam.

[0082] Further, in some possible implementations, the injection section further comprises:

[0083] a mixing section 300d, the mixing section 300d being communicated at the wide end of the divergent injection section 300c, and being used to connect a foam delivery pipe of the fabric treatment device, so as to make the foam flow into the fabric treatment drum of the fabric treatment device through the foam delivery pipe;

[0084] wherein the mixing section 300d is a thin straight pipe section, and the caliber of the mixing section 300d is greater than or equal to the caliber of the wide end of the divergent injection section 300c.

[0085] In this embodiment, the mixing section 300d is a thin, straight pipe section with a diameter greater than or equal to the flared port diameter of the gradually expanding spray section 300c. This design helps to smooth the transition of foam from the gradually expanding spray section 300c to the foam delivery pipe, reducing foam breakage and loss during the conversion process. Simultaneously, the diameter design of the mixing section 300d helps to improve the foam delivery efficiency from the nozzle to the foam delivery pipe, ensuring that the foam can flow smoothly into the fabric processing cylinder of the fabric processing equipment.

[0086] Furthermore, in some possible embodiments, the nozzle 300 is also provided with an air intake 301, one end of which is connected to the jet section 300b of the nozzle 300, and the other end is used to connect to the ozone generator.

[0087] When the nozzle 300 sprays foam, a negative pressure can be generated inside the jet section 300b, so that the ozone gas generated by the ozone generator can be drawn into the jet section 300b and mixed with the foam through the negative pressure.

[0088] In this embodiment, ozone gas generated by the ozone generator is drawn into the jet section 300b through the air intake 301 and mixed with foam, thereby enhancing the foam's antibacterial function. Ozone is a strong oxidant that can effectively kill bacteria and viruses, improving hygiene and safety during the washing process. Specifically, the negative pressure generated inside the jet section 300b can effectively draw in ozone gas and mix it with foam, making the ozone distribution in the foam more uniform, thus improving the consistency of the antibacterial effect.

[0089] Furthermore, in some possible embodiments, the foam generating chamber 100 includes a cylindrical foaming chamber 100a and a conical collecting chamber 100b, with the foaming module 200 disposed within the cylindrical foaming chamber 100a.

[0090] The narrow end of the bottom of the collecting cavity 100b is connected to the nozzle 300, and the diameter of the flared end of the collecting cavity 100b is larger than the diameter of the air inlet port of the nozzle 300.

[0091] In this embodiment, by designing the foam generating chamber 100 as a cylindrical foaming chamber 100a and a conical collecting chamber 100b, the foam generation and collecting process can be controlled more effectively. The cylindrical structure is conducive to stable foam generation, while the conical structure helps the foam to concentrate and flow. The conical structure of the collecting chamber 100b helps the foam to concentrate at the narrow end at the bottom, thereby improving the flowability and spraying effect of the foam when passing through the nozzle 300.

[0092] In this embodiment, a conical collecting chamber 100b is added to the end of the foaming chamber 100a. This allows the foam to collect and be ejected from the nozzle 300, forming a high-speed jet in the narrowed jet section 300b. The jet then passes through a conical, gradually expanding spray section 300c and enters a mixing section 300d with a larger pipe diameter. The compression and acceleration from the nozzle 300 causes the larger foam generated by aeration to break down into finer foam, which is then thoroughly mixed with the washing water.

[0093] It is worth noting that the air inlet 301 mentioned above can also be connected to the water inlet pipe to draw in washing water, which can further increase foam production and fluidity. This ensures the total amount of foam water entering the machine and prevents the washing water from entering the foam generator cavity and causing excessive water pressure, making it difficult for the aeration head to release air.

[0094] Furthermore, in some possible implementations, the foaming cavity 100a is a cylindrical cavity extending vertically, and the collecting cavity 100b is a conical cavity extending vertically.

[0095] The foaming module 200 includes an aeration device disposed in the foaming chamber 100a, and the central axis of the aeration device coincides with the central axis of the foaming chamber 100a.

[0096] In this embodiment, both the foaming chamber 100a and the collecting chamber 100b are vertically extending cylindrical and conical cavities, respectively. This symmetrical structure helps maintain the uniformity of foam generation, ensuring that the foam is evenly distributed throughout the foaming chamber 100a. The central axis of the aeration device coincides with the central axis of the foaming chamber 100a. This design ensures that the aeration device distributes gas evenly throughout the foaming process, improving aeration efficiency and generating more uniform and finer foam. The central position of the aeration device helps optimize the kinetics of foam generation, allowing the foam to mix more effectively with the detergent water during generation, forming abundant foam. Furthermore, the symmetrical cylindrical and conical structures provide good structural stability and strength, helping to withstand pressure changes that may occur during foam generation.

[0097] Furthermore, in some possible embodiments, the foam generator also includes a connecting rib 302 connected between the outer wall of the nozzle 300 and the outer wall of the foam generating chamber 100;

[0098] Multiple connecting ribs 302 are provided, and the multiple connecting ribs 302 are distributed on the outer periphery of the nozzle 300.

[0099] The connecting ribs 302 in this embodiment can significantly enhance the connection strength between the nozzle 300 and the foam generating chamber 100, improving the stability and durability of the overall structure. This also increases the structural strength of the small tube segments in the nozzle 300.

[0100] Furthermore, in some possible implementations, the foam generating chamber includes a chamber body and a chamber cover, the chamber body and the front cover being pressed together and sealed by a locking structure;

[0101] The cavity is provided with a liquid inlet, and the cavity cover is provided with an air inlet 102 for air to enter the foaming module 200.

[0102] Preferably, the cavity box and cavity cover can be assembled and sealed by means of snap-fit, hot plate welding, screw fastening, etc.

[0103] It is worth noting that in some alternative implementations, the foaming cavity described above can also be split left and right along the central axis of symmetry and then combined to form a single component.

[0104] Furthermore, a second aspect of the present application also provides a fabric treatment apparatus, which includes the foam generator 10 provided in the first aspect of the present application.

[0105] Furthermore, in some possible implementations, the fabric treatment equipment includes:

[0106] The detergent dispensing module 400 and the fabric treatment cylinder 500 are provided. An inlet pipe 600 is provided between the detergent dispensing module 400 and the foam generator 10. The inlet pipe 600 is used to dispense detergent water mixed with detergent and washing water into the foam generation chamber 100 of the foam generator 10. A foam delivery pipe 700 is provided between the foam generator 10 and the fabric treatment cylinder 500. The foam delivery pipe 700 is used to dispense the foam generated in the foam generator 10 into the fabric treatment cylinder 500.

[0107] Furthermore, in some possible implementations, the fabric treatment apparatus further includes:

[0108] An ozone generator 800 is connected to a foam generator 10 so that the ozone gas generated by the ozone generator 800 can adhere to the foam generated by the foam generator 10.

[0109] In this embodiment, by connecting the ozone generator to the foam generator, ozone gas can directly adhere to the foam. Utilizing the strong oxidizing properties of ozone, the sterilization effect of the fabric treatment equipment is improved. Ozone gas can decompose the active ingredients in detergent, making it more effective at removing stains and thus improving the cleaning effect. The oxidizing effect of ozone helps prevent color mixing and fading of clothing, while its disinfecting effect also helps to soften clothing and reduce damage during washing. In this embodiment, the introduction of ozone gas can alter the physical properties of the foam, potentially making it finer and more stable, thereby improving the washing effect.

[0110] Furthermore, in some possible implementations, the ozone generator 800 includes an ozone generator 801, an air pump 802, and an air pipe 803, wherein the ozone generator 801 is connected to the foaming module 200 of the foam generator 10 via the air pipe 803.

[0111] The air pipe 803 is equipped with an air inlet check valve 804, which is designed to allow fluid to flow out of the ozone generator 801 and restrict the fluid from flowing back to the ozone generator 801.

[0112] In this embodiment, the combination of ozone generator 801, air pump 802, and air pipe 803 allows for precise control of ozone generation and supply, ensuring that the foam in foam generator 10 is uniformly covered by ozone gas. The design of the one-way inlet valve 804 allows gas to flow from ozone generator 801 to foam generator 10 while preventing backflow. This helps prevent excessive pressure inside ozone generator 801, ensuring safe operation of the equipment. The use of the one-way valve ensures that ozone gas is not wasted; all generated ozone is effectively used for foam generation and treatment, improving ozone utilization efficiency.

[0113] Furthermore, in some possible implementations, the detergent dispensing module 400 also includes:

[0114] At least one storage chamber 401 for storing detergent and / or fabric softener, and a detergent dissolving chamber 403 connected to the storage chamber 401 via a dispensing pump 402;

[0115] The detergent dosage and / or softening dosage pumped from the storage chamber 401 to the detergent dissolving chamber 403 can be controlled by controlling the operation of the dispensing pump 402. The detergent dissolving chamber 403 is connected to the foam generator 10 through the liquid inlet pipe 600.

[0116] In this embodiment, by mixing detergent and washing water in the detergent dissolving chamber and then conveying it to the foam generator for foaming, the detergent can be ensured to be fully dissolved and dispersed in the water, thereby improving washing efficiency and cleaning effect. Furthermore, in this embodiment, by controlling the operation of the dispensing pump, the dosage of detergent and / or fabric softener pumped from the storage chamber into the detergent dissolving chamber can be precisely controlled, thereby improving washing effect and garment care quality. Simultaneously, since the detergent and / or fabric softener are pumped into the detergent dissolving chamber through the dispensing pump, the pressure of the detergent and / or fabric softener entering the detergent dissolving chamber can be increased, allowing the detergent and / or fabric softener to be fully mixed with the washing water entering the detergent dissolving chamber through the water inlet pipe to form detergent water, thereby improving the foaming effect of the subsequent foam generator on the detergent water.

[0117] Furthermore, in some possible embodiments, the fabric treatment equipment also includes a water inlet pipe 900, which includes:

[0118] The first water inlet pipe 901 is used to inject washing water into the detergent dissolving chamber 403;

[0119] The second water inlet pipe 902 is used to spray washing water into the window gasket folds of the fabric treatment drum 500.

[0120] The third water inlet pipe 903 is used to inject washing water into the fabric treatment drum 500.

[0121] in

[0122] The first water inlet pipe 901, the second water inlet pipe 902 and the third water inlet pipe 903 are each equipped with a separate water inlet valve;

[0123] or

[0124] At least two of the first water inlet pipe 901, the second water inlet pipe 902, and the third water inlet pipe 903 share a single water inlet valve.

[0125] In this embodiment, each water inlet pipe is equipped with an independent inlet valve, which can precisely control the water flow in each pipe and ensure that the water flow requirements of each part are met during the washing process. It is worth noting that when considering the setting of the water inlet pipes from the perspective of saving costs and installation space, at least two water inlet pipes can share one inlet valve {not shown in the figure}.

[0126] Preferably, the aforementioned third water inlet pipe 903 is connected to a manual dispensing device for manually dispensing detergent.

[0127] Furthermore, in some possible embodiments, the fabric processing cylinder 500 includes an outer cylinder and an inner cylinder pivotally disposed within the outer cylinder, and the fabric processing device is a roller-type fabric processing device with an outer cylinder and an inner cylinder.

[0128] It is worth noting that the aforementioned foam generator is installed above the window pad of the fabric treatment equipment, near the center, and to the right of the automatic detergent dispensing device, so as to connect with the foam nozzle located in the center of the top of the observation window and the liquid inlet pipe on the upper left of the fabric treatment equipment.
