Description

Technical Field

[0001] This application relates to the field of fabric treatment equipment, and more specifically, to a fabric treatment device and a foam control method. Background Art

[0002] Fabric treatment equipment refers to devices capable of washing fabrics, shoes, hats, and other items, and is an indispensable appliance in modern households. During the use of fabric treatment equipment, detergent is added. The detergent not only improves the cleanliness of the fabric but also generates foam, which provides effective cleaning and conditioning. However, current fabric treatment equipment relies on agitating the mixture of detergent and water to generate foam, which is insufficient to meet the foam treatment needs of different fabrics, thus reducing the washing effect. Summary of the Invention

[0003] This application provides a fabric treatment device and a foam control method to at least solve the technical problem of poor washing effect.

[0004] According to a first aspect of the embodiments of this application, a fabric treatment device is provided, the fabric treatment device comprising a treatment tank, an automatic detergent dispensing device, a foam generator, a mixer, a first water inlet pipe, a second water inlet pipe, a detergent water delivery pipe, a first foam delivery pipe, and a second foam delivery pipe, wherein:

[0005] The water supply end of the first water inlet pipe is connected to the water inlet of the automatic detergent dispensing device, which can provide foaming water to the automatic detergent dispensing device to mix with the detergent to be dispensed to form washing water containing detergent.

[0006] The washing water outlet of the automatic detergent dispensing device is connected to the inlet of the detergent water delivery pipeline, and the other end of the detergent water delivery pipeline is connected to the inlet of the foam generator; a first control valve is provided on the first water inlet pipeline, which can be used to control the amount of water entering the foam generator.

[0007] The air inlet of the foam generator is connected to the foaming gas supply device, the foam outlet is connected to the inlet end of the first foam delivery pipeline, and the outlet end of the first foam delivery pipeline is connected to the first liquid inlet of the mixer to supply foam liquid to the mixer.

[0008] The mixer is further provided with a second liquid inlet, which is connected to the water supply end of the second water inlet pipe to provide mixed water to the foam liquid entering the mixer to dilute the foam liquid. The second water inlet pipe is provided with a second control valve; the second control valve can be used to control the amount of mixed water entering the foam liquid.

[0009] The outlet of the mixer is connected to one end of the second foam delivery pipeline, and the other end of the second foam delivery pipeline is connected to the fabric processing chamber of the processing tank to apply foam liquid to the fabric in the fabric processing chamber.

[0010] In this embodiment, the mixed water in the second inlet pipe and the foam liquid output by the foam generator can be mixed in the mixer. By changing the ratio between the mixed water and the foam liquid entering the mixer, the condition of the foam liquid entering the fabric processing chamber can be freely changed. For example, the foam content and the fluidity of the foam liquid entering the fabric processing chamber can be changed, so that the fabric in the fabric processing chamber can obtain the required foam liquid, thus improving the washing effect.

[0011] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the fabric processing equipment is provided with a controller, which is configured to control the first control valve and the second control valve according to the load characteristics of the fabric processing equipment so that the foam liquid delivered into the fabric processing chamber by the second foam delivery pipeline meets the foam processing requirements of the load.

[0012] In this embodiment, the controller can automatically control the first control valve and the second control valve, so that the foam liquid delivered into the fabric processing chamber meets the foam processing requirements of the load. This method is highly automated and helps to improve the washing effect of the load.

[0013] In conjunction with the first aspect, in an optional implementation of this application embodiment, controlling the first control valve and the second control valve according to the load characteristics of the fabric processing equipment to ensure that the foam liquid delivered into the fabric processing chamber by the second foam delivery pipeline meets the foam processing requirements of the load includes:

[0014] The on / off state and / or on / off cycle and / or on / off duration of the first control valve and / or the second control valve are controlled according to the material and / or weight and / or stain characteristics of the load, so that the foam state of the foam liquid supplied to the load meets the foam treatment requirements, the foam treatment requirements including at least one of foam concentration, fluidity and fineness.

[0015] In this embodiment, at least one of the foam concentration, fluidity, and fineness can be changed, making the foam liquid entering the fabric treatment chamber more suitable for the load requirements, thereby improving the washing effect of the load.

[0016] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the foaming gas supply device is an ozone supply device, and the foam generator uses the ozone provided by the ozone supply device to generate foam.

[0017] In this embodiment, ozone is used to generate foam, which can sterilize the load after the foam comes into contact with it, thus helping to improve the washing effect of the load.

[0018] According to a second aspect of the present application, a foam control method for the above-described fabric treatment equipment is provided, the method comprising:

[0019] Obtain foam treatment requirements, including the foam state of the foam supplied to the treatment tank;

[0020] During the operation of the foam generator, the liquid inlet of the first water inlet pipe and the second water inlet pipe is controlled according to the foam treatment requirements, so that the foam liquid supplied to the treatment tank meets the foam treatment requirements.

[0021] In this embodiment, the fabric treatment equipment is equipped with a foam generator. When foam needs to be supplied to the treatment tank, the foam generator can be directly controlled to supply foam to the treatment tank, eliminating the need to rely on the treatment tank to agitate the mixture of detergent and water to generate foam. This increases the amount of foam and allows for flexible control of the timing of foam supply, ensuring sufficient foam for the load in the treatment tank and allowing for full contact between the load and the foam, thus improving the washing effect. Simultaneously, the mixed water from the second inlet pipe and the foam liquid output from the foam generator can be mixed in the mixer. By changing the ratio of mixed water to foam liquid entering the mixer, the condition of the foam liquid entering the fabric treatment chamber can be freely altered, such as changing the foam content and flowability of the foam liquid entering the fabric treatment chamber. This ensures that the fabric in the fabric treatment chamber receives the required foam liquid, further improving the washing effect.

[0022] In conjunction with the second aspect, in one optional implementation of the embodiments of this application, the foam state includes at least one of foam concentration, fluidity, and fineness;

[0023] The step of controlling the liquid inlet of the first and second inlet pipes according to the foam treatment requirements includes:

[0024] Based on the size of at least one of the foam states, control the liquid inlet of the first water inlet pipe and determine the first liquid inlet parameter of the first water inlet pipe, or control the liquid inlet of the first water inlet pipe and the second water inlet pipe and determine the first liquid inlet parameter and the second liquid inlet parameter of the second water inlet pipe.

[0025] By adopting this implementation method, while using different liquid inlet methods, corresponding liquid inlet parameters are also determined. This ensures that when the required foam concentration, fluidity, and fineness are different, the liquid inlet parameters will also be different, which is beneficial for providing foam in different states and improving the washing effect.

[0026] In conjunction with the second aspect, in an optional implementation of this application embodiment, the step of controlling the liquid inflow into the first inlet pipe and determining a first liquid inflow parameter of the first inlet pipe based on the size of at least one of the foam states, or controlling the liquid inflow into both the first and second inlet pipes and determining the first liquid inflow parameter and a second liquid inflow parameter of the second inlet pipe, includes:

[0027] If the concentration exceeds the preset target concentration parameter, then the first inlet pipe is controlled to supply liquid; otherwise, both the first and second inlet pipes are controlled to supply liquid.

[0028] Alternatively, if the flowability exceeds the preset target flow parameter, then control the inlet flow of liquid into the first and second inlet pipes; otherwise, control the inlet flow of liquid into the first inlet pipe.

[0029] Alternatively, if the fineness exceeds the preset target fineness parameter, then control the first water inlet pipe to supply liquid; otherwise, control the first water inlet pipe and the second water inlet pipe to supply liquid.

[0030] By adopting this implementation method, the concentration characterized by the foam treatment requirement is compared with the target concentration parameter to determine which liquid injection method to use. This makes the liquid injection method determination process simple and convenient, with low computational load, which can easily reduce the occupation of computing resources and reduce computing costs.

[0031] In conjunction with the second aspect, in an optional implementation of the embodiments of this application, the concentration includes a concentration value or a concentration level, the first liquid inlet parameter includes at least one of a first liquid inlet duration, a first flow rate and a foaming water concentration, and the second liquid inlet parameter includes at least one of a second liquid inlet duration and a second flow rate.

[0032] Determining the first inlet parameters of the first water inlet pipeline includes:

[0033] The higher the concentration value or concentration level, the greater at least one of the first liquid inlet duration, the first flow rate, and the foaming water concentration;

[0034] Determining the first inlet parameters and the second inlet parameters of the second inlet pipeline includes:

[0035] The smaller the concentration value or concentration level, the smaller at least one of the first liquid inlet time, the first flow rate, and the foaming water concentration, and / or the smaller the concentration value or concentration level, the larger at least one of the second liquid inlet time and the second flow rate.

[0036] By adopting this method, the required foam concentration value or concentration level can be adjusted by changing the liquid inlet time, flow rate and foaming water concentration of the corresponding pipeline and the first inlet water pipeline, so that the foam concentration entering the treatment tank is more in line with the washing requirements of the load in the treatment tank, thereby improving the washing effect.

[0037] In conjunction with the second aspect, in an optional implementation of the embodiments of this application, the foam state includes concentrated foam and dilute foam, wherein the concentration of the concentrated foam is greater than the concentration of the dilute foam;

[0038] The step of controlling the liquid inlet of the first and second inlet pipes according to the foam treatment requirements includes:

[0039] If the foam treatment requirement indicates that the foam needed is concentrated foam, then control the first water inlet pipe to supply liquid and close the second water inlet pipe.

[0040] If the foam treatment requirement indicates that the foam needed is the dilute foam, then control the liquid intake of the first and second water inlet pipes.

[0041] By adopting this implementation method, the state of both concentrated and dilute foam is directly set, and it can be directly determined whether to use the first inlet pipe or both the first and second inlet pipes simultaneously to inject liquid. This simplifies the liquid injection method determination process, improves the efficiency of providing foam to the treatment tank, reduces the amount of calculation, and lowers the computational cost.

[0042] In conjunction with the second aspect, in an optional implementation of the embodiments of this application, the foam state further includes a custom concentration state;

[0043] The step of controlling the liquid inlet of the first and second inlet pipes according to the foam treatment requirements includes:

[0044] If the foam treatment requirement indicates that the foam needs to be of a custom concentration, then the first and second inlet pipes are intermittently fed with liquid according to a preset first opening and closing cycle, or a second opening and closing cycle is obtained and the first and second inlet pipes are intermittently fed with liquid according to the second opening and closing cycle.

[0045] This implementation method also allows for customization of concentration levels and intermittent liquid inlet control of the first and second inlet pipes, which helps meet user needs and improves the user experience of the fabric processing equipment.

[0046] In conjunction with the second aspect, in an optional implementation of the embodiments of this application, the method further includes:

[0047] The foam treatment requirement indicates that the higher the concentration of foam required, the longer the detergent dispensing time of the automatic detergent dispensing device and / or the shorter the foaming and water inlet time of the automatic detergent dispensing device.

[0048] The foam treatment requirement indicates that the lower the required foam concentration, the shorter the detergent dispensing time of the automatic detergent dispensing device and / or the longer the foaming and water inlet time of the automatic detergent dispensing device.

[0049] Using this implementation method, the foam concentration entering the treatment tank can also be changed by adjusting the detergent dosing time and / or the water inlet time, which improves the flexibility of foam concentration adjustment.

[0050] In conjunction with the second aspect, in one optional implementation of the embodiments of this application, obtaining the foam treatment requirements includes:

[0051] Obtain the weight and / or material of the fabric inside the processing barrel;

[0052] The foam treatment requirements are determined based on the fabric weight and / or fabric material.

[0053] By adopting this method, the foam treatment requirements are determined based on the fabric weight and / or fabric material, making the foam treatment requirements more closely match the actual foam treatment requirements of the fabric in the treatment tank, which helps to improve the washing effect of the fabric.

[0054] In conjunction with the second aspect, in an optional implementation of the embodiments of this application, the method further includes:

[0055] In response to a pre-coating signal, a pre-coating requirement is obtained, wherein the pre-coating requirement characterizes the required concentration of ultra-concentrated foam;

[0056] Control the first water inlet pipe to introduce foaming water and adjust the detergent dispensing time and / or the foaming water inlet time of the automatic detergent dispensing device according to the pre-coating requirements. The pre-coating requirements indicate that the higher the concentration of the required ultra-concentrated foam, the longer the detergent dispensing time and / or the shorter the foaming water inlet time.

[0057] Control the foam generator to output foam liquid to the processing tank.

[0058] Using this method, when pre-coating fabrics with foam, the liquid inlet of the first water inlet pipe is directly controlled and the detergent dosing time and / or foaming water inlet time are adjusted, so that the fabrics in the treatment tank can be pre-coated with super-concentrated foam before washing, which helps to increase the contact time between the foam and the fabric, thereby improving the washing effect of the fabrics.

[0059] According to a third aspect of the embodiments of this application, a control method for a fabric processing device is provided, employing the foam control method described above.

[0060] In conjunction with the second aspect, in an optional implementation of the embodiments of this application, the method further includes:

[0061] In response to the pre-coating signal, it is determined whether the foam generator outputs foam liquid to the processing tank;

[0062] If so, after the foam generator finishes outputting foam liquid, the processing tank will be controlled to rotate after waiting for a preset target time.

[0063] Using this method, during foam pre-coating, the process waits for the target time before controlling the rotation of the treatment tank, which helps to increase the contact time between the foam and the fabric, thereby improving the washing effect of the fabric.

[0064] According to a fourth aspect of the embodiments of this application, a fabric treatment apparatus is provided, employing the foam control method described above or the control method described above.

[0065] In conjunction with the fourth aspect, in one optional implementation of the embodiments of this application, the fabric processing equipment includes a liquid inlet module, a liquid processing module, and a processing tank;

[0066] The water supply end of the liquid inlet module is connected to the liquid inlet of the liquid processing module, and is used to provide the liquid processing module with washing water containing detergent.

[0067] The foam outlet of the liquid processing module is connected to the processing tank and is used to process the washing water containing detergent into foam liquid, and to transport the processed foam liquid into the processing tank.

[0068] The liquid inlet module is also used to introduce mixed water into the foam liquid delivered by the liquid processing module.

[0069] Using this implementation method, the liquid processing module can process the mixture to generate foam, so that the mixture entering the processing tank contains foam, allowing the load to come into contact with the foam earlier and improving the washing effect.

[0070] In conjunction with the fourth aspect, in an optional implementation of the embodiments of this application, the liquid processing module includes an ozone generator and a foam generator, the inlet of the foam generator is connected to the water supply end of the liquid inlet module, and the outlet of the foam generator is connected to the fabric processing chamber of the processing tank.

[0071] The ozone generator is used to deliver ozone into the foam generator.

[0072] Using this method, the ozone generator can deliver ozone into the foam generator, so that the foam entering the treatment tank contains ozone. When the ozone comes into contact with the load, it can sterilize and improve the washing effect.

[0073] In conjunction with the fourth aspect, in one optional implementation of the embodiments of this application, the fabric processing equipment includes at least one of a washing machine and a washer-dryer combo.

[0074] The technical effects achieved by the second to fourth aspects mentioned above are similar to those achieved by the corresponding technical means in the first aspect, and will not be repeated here. Attached Figure Description

[0081] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0082] It should be understood that "multiple" as mentioned herein refers to two or more. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, to facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first," "second," etc., are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and the terms "first," "second," etc., do not necessarily imply differentness.

[0083] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0084] Detergent foam plays a significant role in cleaning and softening fabrics during the washing process. However, most washing machines currently lack active foam generators, requiring a period of washing before foam production. This results in slower detergent effectiveness, and some detergent may not dissolve completely in the water, impacting cleaning results.

[0085] Furthermore, regarding health and sterilization, gases like ozone, which have good sterilization properties, are difficult to dissolve in water and therefore cannot provide effective sterilization during washing. However, they can adhere to the surface of foam and be encapsulated within it, achieving a good sterilization effect during foam-fabrication contact. Current foam washing systems fail to fully integrate sterilization functionality, focusing solely on washing performance.

[0086] In addition, when foam washing is used in washing machines, issues such as the fineness of the foam, the water content of the foam, and the control of its flowability need to be addressed.

[0087] Based on this, embodiments of this application provide a fabric treatment device and a foam control method. Taking a drum washing machine as an example, the fabric treatment device and foam control method can at least solve one of the following technical problems:

[0088] 1. Solved the problems of foam fineness, moisture content (foam concentration) and flowability control in ozone foam washing machines.

[0089] 2. The problem of selecting different foam concentrations and specific implementation methods for foam washing has been solved.

[0090] 3. The problem of controlling the implementation of foam pre-coating washing has been solved.

[0091] Next, the fabric processing equipment provided in the embodiments of this application will be described in detail.

[0092] A fabric treatment device includes a treatment tank, an automatic detergent dispensing device, a foam generator, a mixer, a first water inlet pipe, a second water inlet pipe, a detergent water delivery pipe, a first foam delivery pipe, and a second foam delivery pipe, wherein:

[0093] The water supply end of the first water inlet pipe is connected to the water inlet of the automatic detergent dispensing device, which can provide foaming water to the automatic detergent dispensing device to mix with the detergent to be dispensed to form washing water containing detergent.

[0094] The washing water outlet of the automatic detergent dispensing device is connected to the inlet of the detergent water delivery pipeline, and the other end of the detergent water delivery pipeline is connected to the inlet of the foam generator; a first control valve is provided on the first water inlet pipeline, which can be used to control the amount of water entering the foaming process.

[0095] The air inlet of the foam generator is connected to the foaming gas supply device, the foam outlet is connected to the inlet end of the first foam delivery pipeline, and the outlet end of the first foam delivery pipeline is connected to the first liquid inlet of the mixer to supply foam liquid to the mixer.

[0096] The mixer is also provided with a second liquid inlet, which is connected to the water supply end of the second water inlet pipe to provide mixed water to the foam liquid entering the mixer to dilute the foam liquid. A second control valve is provided on the second water inlet pipe; the second control valve can be used to control the amount of mixed water entering the foam liquid.

[0097] The outlet of the mixer is connected to one end of the second foam delivery pipeline, and the other end of the second foam delivery pipeline is connected to the fabric processing chamber of the processing tank to apply foam liquid to the fabric in the fabric processing chamber.

[0098] In one embodiment, the automatic detergent dispensing device can store detergent. A first water inlet pipe can be connected to a tap, allowing tap water to enter the device as foaming water and mix with the detergent to form washing water. Because the washing water contains detergent, it can generate foam, thus producing foam liquid. Upon startup, the detergent in the automatic detergent dispensing device can be added manually or automatically; this embodiment does not specifically limit this.

[0099] The mixer mixes foam concentrate with water, increasing the water content and thus diluting the foam concentrate. When the ratio of water to the original foam concentrate differs, the foam concentration and flowability of the diluted foam concentrate will also vary.

[0100] In this embodiment, the mixed water in the second inlet pipe and the foam liquid output by the foam generator can be mixed in the mixer. By changing the ratio between the mixed water and the foam liquid entering the mixer, the condition of the foam liquid entering the fabric processing chamber can be freely changed. For example, the foam content and the fluidity of the foam liquid entering the fabric processing chamber can be changed, so that the fabric in the fabric processing chamber can obtain the required foam liquid, thus improving the washing effect.

[0101] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the fabric processing equipment is provided with a controller, which is configured to control a first control valve and a second control valve according to the load characteristics of the fabric processing equipment so that the foam liquid delivered into the fabric processing chamber by the second foam delivery pipeline meets the foam processing requirements of the load.

[0102] In one embodiment, load characteristics include features that reflect the characteristics of the load, such as the material of the load, the weight of the load, etc., which are not specifically limited in this embodiment. When the load characteristics are different, the foam treatment requirements of the load are likely to be different. For example, for materials that do not easily absorb foam, such loads require a larger amount of foam.

[0103] In this embodiment, the controller can automatically control the first control valve and the second control valve, so that the foam liquid delivered into the fabric processing chamber meets the foam processing requirements of the load. This method is highly automated and helps to improve the washing effect of the load.

[0104] In conjunction with the first aspect, in an optional implementation of this application embodiment, controlling the first control valve and the second control valve according to the load characteristics of the fabric processing equipment to ensure that the foam liquid delivered into the fabric processing chamber by the second foam delivery pipeline meets the foam processing requirements of the load includes:

[0105] The on / off state and / or on / off cycle and / or on / off duration of the first control valve and / or the second control valve are controlled according to the material and / or weight and / or stain characteristics of the load, so that the foam state of the foam liquid supplied to the load meets the foam treatment requirements, which include at least one of foam concentration, fluidity and fineness.

[0106] In one embodiment, the material is, for example, cotton or linen, and the stain characteristics include the type of stain, such as oil or dust. Different on / off states, different on / off cycles, and different on / off durations can all alter the ratio of mixed water to the pre-diluted foam liquid, thus changing the foam state of the foam liquid entering the fabric treatment chamber to meet foam treatment requirements.

[0107] In this embodiment, at least one of the foam concentration, fluidity, and fineness can be changed, making the foam liquid entering the fabric treatment chamber more suitable for the load requirements, thereby improving the washing effect of the load.

[0108] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the foaming gas supply device is an ozone supply device, and the foam generator uses the ozone provided by the ozone supply device to generate foam.

[0109] In this embodiment, ozone is used to generate foam, which can sterilize the load after the foam comes into contact with it, thus helping to improve the washing effect of the load.

[0110] This application provides a foam control method for the above-mentioned fabric treatment equipment, referring to... Figure 1 The flowchart shown is a foam control method for the fabric treatment equipment. The method includes the following processing steps.

[0111] S100, Obtain foam treatment requirements.

[0112] The foam treatment requirements include the foam state of the foam supplied to the treatment tank. Specifically, the foam state includes factors such as the amount of foam, the foam concentration, and the flowability of the foam when it enters the treatment tank.

[0113] S102. During the operation of the foam generator, the liquid inlet of the first water inlet pipe and the second water inlet pipe is controlled according to the foam treatment requirements so that the foam liquid supplied to the treatment tank meets the foam treatment requirements.

[0114] Specifically, the liquid can be controlled to enter the first inlet pipe according to the foam treatment requirements, or the liquid can be controlled to enter both the first inlet pipe and the second inlet pipe according to the foam treatment requirements.

[0115] In one embodiment, different foam treatment requirements necessitate different liquid inlet methods. Specifically, the liquid inlet methods include a first liquid inlet method that controls liquid inlet through a first water inlet pipe, and a second liquid inlet method that controls liquid inlet through both the first and second water inlet pipes.

[0116] It should be noted that because the liquids output from the first and second inlet pipes are different, and the output locations of the liquids are also different, the state of the foam entering the treatment tank will be changed.

[0117] In this embodiment, the fabric treatment equipment is equipped with a foam generator. When foam needs to be supplied to the treatment tank, the foam generator can be directly controlled to supply foam to the treatment tank, eliminating the need to rely on the treatment tank to agitate the mixture of detergent and water to generate foam. This increases the amount of foam and allows for flexible control of the timing of foam supply, ensuring sufficient foam for the load in the treatment tank and allowing for full contact between the load and the foam, thus improving the washing effect. Simultaneously, the mixed water from the second inlet pipe and the foam liquid output from the foam generator can be mixed in the mixer. By changing the ratio of mixed water to foam liquid entering the mixer, the condition of the foam liquid entering the fabric treatment chamber can be freely altered, such as changing the foam content and flowability of the foam liquid entering the fabric treatment chamber. This ensures that the fabric in the fabric treatment chamber receives the required foam liquid, further improving the washing effect.

[0118] In one possible embodiment of this application, the foam state includes at least one of foam concentration, fluidity, and fineness;

[0119] Controlling the liquid inlet flow of the first and second inlet pipes according to the foam treatment requirements includes:

[0120] Based on the size of at least one of the foam states, control the liquid inlet of the first water inlet pipe and determine the first liquid inlet parameter of the first water inlet pipe, or control the liquid inlet of the first water inlet pipe and the second water inlet pipe and determine the first liquid inlet parameter and the second liquid inlet parameter of the second water inlet pipe.

[0121] In one embodiment, the concentration can be expressed as a concentration value or a concentration level; this embodiment does not specifically limit this.

[0122] In one embodiment, the concentration has magnitude; for example, the concentration value has a numerical magnitude, and the concentration level has a grade magnitude.

[0123] Flowability reflects the fluidity of foam. In one embodiment, the magnitude of flowability can be represented by the ratio of foam volume to water volume. Specifically, the larger the foam volume, the smaller the fluidity, and the larger the water volume, the greater the fluidity.

[0124] Fineness reflects the stability, size, and uniformity of foam size. Specifically, the size and uniformity of foam size are related to the model of the foam generator, while the stability of foam is related to the amount of foam and the amount of water entering the bubble. The larger the amount of foam, the lower the stability, and the larger the amount of water entering the bubble, the greater the stability.

[0125] Since the concentration, fluidity, and fineness of foam are at least related to the amount of foam and the amount of water entering the system, the foam state can be changed by altering the foaming water intake of the first water inlet pipe and the water intake of the second water inlet pipe.

[0126] In this embodiment, while using different liquid inlet methods, corresponding liquid inlet parameters are also determined. When the required foam concentration, fluidity, and fineness are different, the liquid inlet parameters are also different, which helps to provide foam in different states and improve the washing effect.

[0127] Optionally, in one implementation of this embodiment, controlling the liquid inlet of the first water inlet pipe and determining the first liquid inlet parameter of the first water inlet pipe according to the size of at least one of the foam states, or controlling the liquid inlet of the first water inlet pipe and the second water inlet pipe and determining the first liquid inlet parameter and the second liquid inlet parameter of the second water inlet pipe, includes:

[0128] If the concentration required for foam treatment exceeds the preset target concentration parameter, then the first inlet pipe is controlled to supply liquid; otherwise, both the first and second inlet pipes are controlled to supply liquid.

[0129] Alternatively, if the required foam flowability, as indicated by the foam treatment demand, exceeds the preset target flow parameter, then the first and second inlet pipes will be controlled to allow liquid to enter; otherwise, the first inlet pipe will be controlled to allow liquid to enter.

[0130] Alternatively, if the required foam fineness, as indicated by the foam treatment demand, exceeds the preset target fineness parameter, then the first water inlet pipe is controlled to allow liquid to enter; otherwise, both the first and second water inlet pipes are controlled to allow liquid to enter.

[0131] In one embodiment, since the concentration may be a concentration value or a concentration level, the target concentration parameter can be set according to the concentration when it is preset. Specifically, the target concentration parameter includes a target concentration threshold corresponding to the concentration value or a target level threshold corresponding to the concentration level.

[0132] It should be noted that in this embodiment, the higher the concentration level, the greater the foam concentration.

[0133] By adopting this implementation method, the concentration state characterized by the foam treatment requirement is compared with the target concentration parameter to determine which liquid injection method to use. This makes the liquid injection method determination process simple and convenient, with low computational load, which can easily reduce the occupation of computing resources and reduce computing costs.

[0134] Optionally, in one implementation of this embodiment, the concentration includes a concentration value or a concentration level, the first inlet parameter includes at least one of a first inlet duration, a first flow rate and a foaming inlet water concentration, and the second inlet parameter includes at least one of a second inlet duration and a second flow rate.

[0135] Determine the first inlet parameters for the first inlet water pipeline, including:

[0136] The higher the concentration value or concentration level, the greater at least one of the first inlet liquid duration, the first flow rate, and the foaming inlet water concentration;

[0137] Determine the first inlet parameters and the second inlet parameters of the second inlet pipeline, including:

[0138] The smaller the concentration value or concentration level, the smaller at least one of the first inlet time, the first flow rate, and the foaming inlet concentration, and / or, the smaller the concentration value or concentration level, the larger at least one of the second inlet time and the second flow rate.

[0139] In one embodiment, the first liquid inlet duration refers to the duration of foaming water entering the foam generator, and the first flow rate refers to the flow rate of foaming water; the second liquid inlet duration refers to the duration of water entering the path in the second water inlet pipe, and the second flow rate refers to the flow rate of water in the second water inlet pipe.

[0140] By adopting this method, the required foam concentration value or concentration level can be adjusted by changing the liquid inlet time, flow rate and foaming water concentration of the corresponding pipeline and the first inlet water pipeline, so that the foam concentration entering the treatment tank is more in line with the washing requirements of the load in the treatment tank, thereby improving the washing effect.

[0141] Optionally, in one implementation of this embodiment, the foam state includes concentrated foam and dilute foam, wherein the concentration of the concentrated foam is greater than the concentration of the dilute foam;

[0142] Controlling the liquid inlet flow of the first and second inlet pipes according to the foam treatment requirements includes:

[0143] If the foam treatment requirement indicates that the foam to be concentrated, then control the liquid inlet of the first water inlet pipe and close the second water inlet pipe.

[0144] If the foam treatment requirement is to produce dilute foam, then control the liquid intake of the first and second inlet pipes.

[0145] In one embodiment, two foam states are preset: thick foam and thin foam, wherein the concentration of thick foam is greater than the concentration of thin foam.

[0146] Furthermore, it should be noted that in other embodiments, as long as the first liquid inlet method is used, the second water inlet pipe is controlled to be closed.

[0147] By adopting this implementation method, the state of both concentrated and dilute foam is directly set, and it can be directly determined whether to use the first inlet pipe or both the first and second inlet pipes simultaneously to inject liquid. This simplifies the liquid injection method determination process, improves the efficiency of providing foam to the treatment tank, reduces the amount of calculation, and lowers the computational cost.

[0148] Optionally, in one implementation of this embodiment, the foam state further includes a custom concentration state;

[0149] Controlling the liquid inlet flow of the first and second inlet pipes according to the foam treatment requirements includes:

[0150] If the foam treatment requirement is a custom concentration, then the first and second inlet pipes are intermittently fed according to the preset first opening and closing cycle, or the second opening and closing cycle is obtained and the first and second inlet pipes are intermittently fed according to the second opening and closing cycle.

[0151] This implementation method also allows for customization of concentration levels and intermittent liquid inlet control of the first and second inlet pipes, thus meeting user needs and improving the user experience of the fabric processing equipment.

[0152] Optionally, in one implementation of this embodiment, the method further includes:

[0153] The foam treatment requirement indicates that the higher the concentration of foam needed, the longer the detergent dispensing time of the automatic detergent dispensing device and / or the shorter the foaming and water inlet time of the automatic detergent dispensing device.

[0154] The lower the required foam concentration, the shorter the detergent dispensing time of the automatic detergent dispensing device and / or the longer the foaming and water inlet time of the automatic detergent dispensing device.

[0155] Using this implementation method, the foam concentration entering the treatment tank can also be changed by adjusting the detergent dosing time and / or the water inlet time, which improves the flexibility of foam concentration adjustment.

[0156] Optionally, in one implementation of this embodiment, obtaining foam treatment requirements includes:

[0157] Obtain the weight and / or material of the fabric inside the processing bucket;

[0158] The foam treatment requirements are determined based on the fabric weight and / or fabric material.

[0159] In one embodiment, a pre-defined relationship table is provided. This table includes fabric weight and / or fabric material and / or fabric soiling level. Different fabric weights and / or fabric materials and / or fabric soiling levels correspond to different foam treatment requirements. When it is necessary to determine the foam treatment requirements, the corresponding foam treatment requirements for the obtained fabric weight and / or fabric material and / or fabric soiling level can be found in the relationship table. The fabric soiling level can be obtained by detecting the fabric's transparency or the turbidity of the washing water; this embodiment does not specifically limit this.

[0160] By adopting this method, the foam treatment requirements are determined based on the fabric weight and / or fabric material, making the foam treatment requirements more closely match the actual foam treatment requirements of the fabric in the treatment tank, which helps to improve the washing effect of the fabric.

[0161] Optionally, in one implementation of this embodiment, the method further includes:

[0162] In response to the pre-coating signal, the pre-coating requirement is obtained, wherein the pre-coating requirement characterizes the required concentration of ultra-concentrated foam;

[0163] Control the first water inlet pipe to introduce foaming water and adjust the detergent dispensing time and / or the foaming water inlet time of the automatic detergent dispensing device according to the pre-coating requirements. The pre-coating requirements indicate that the higher the concentration of the required ultra-concentrated foam, the longer the detergent dispensing time and / or the shorter the foaming water inlet time.

[0164] Control the foam generator to output foam liquid to the treatment tank.

[0165] In one embodiment, a pre-coating signal is generated when foam needs to be pre-coated onto the fabric. The pre-coating signal may be generated after the user selects the pre-coating foam button on the fabric treatment device, or it may be generated by the fabric treatment device according to the settings of the operating program selected by the user. This embodiment does not specifically limit this.

[0166] Among them, the concentration of ultra-concentrated foam is greater than that of concentrated foam. Specifically, this embodiment includes at least three types of foam: ultra-concentrated foam, concentrated foam, and dilute foam. The difference between the three is that ultra-concentrated foam does not need to be mixed with water, and the amount of mixed water mixed in concentrated foam is less than that mixed in dilute foam.

[0167] Using this method, when pre-coating fabrics with foam, the liquid inlet of the first water inlet pipe is directly controlled and the detergent dosing time and / or foaming water inlet time are adjusted, so that the fabrics in the treatment tank can be pre-coated with super-concentrated foam before washing, which helps to increase the contact time between the foam and the fabric, thereby improving the washing effect of the fabrics.

[0168] This application also provides a control method for a fabric processing device, which employs the foam control method described above.

[0169] Optionally, in one implementation of this embodiment, the method further includes:

[0170] In response to the pre-coating signal, determine whether the foam generator is discharging foam liquid into the treatment tank;

[0171] If so, after the foam generator finishes outputting foam liquid, wait for the preset target time before controlling the rotation of the processing tank.

[0172] Using this method, during foam pre-coating, the process waits for the target time before controlling the rotation of the treatment tank, which helps to increase the contact time between the foam and the fabric, thereby improving the washing effect of the fabric.

[0173] The fabric processing equipment provided in this application embodiment adopts the foam control method described above or the control method described above.

[0174] Optionally, in one implementation of this embodiment, such as Figure 2 As shown, the fabric processing equipment includes a liquid inlet module, a liquid processing module, and a processing tank;

[0175] The water supply end of the liquid inlet module is connected to the liquid inlet of the liquid processing module, and is used to provide washing water containing detergent to the liquid processing module;

[0176] The foam outlet of the liquid processing module is connected to the processing tank, and is used to process the washing water containing detergent into foam liquid, and then transport the processed foam liquid into the processing tank.

[0177] The liquid inlet module is also used to introduce mixed water into the foam liquid delivered to the liquid processing module.

[0178] Using this implementation method, the liquid processing module can process the mixture to generate foam, so that the mixture entering the processing tank contains foam, allowing the load to come into contact with the foam earlier and improving the washing effect.

[0179] Optionally, in one implementation of this embodiment, the liquid processing module includes an ozone generator and a foam generator. The inlet of the foam generator is connected to the water supply end of the liquid inlet module, and the outlet of the foam generator is connected to the fabric processing chamber of the processing tank.

[0180] An ozone generator is used to deliver ozone into a foam generator.

[0181] Using this method, the ozone generator can deliver ozone into the foam generator, so that the foam entering the treatment tank contains ozone. When the ozone comes into contact with the load, it can sterilize and improve the washing effect.

[0182] In one embodiment, the mixer is a device capable of mixing foam and water.

[0183] Optionally, in one implementation of this embodiment, the fabric handling equipment includes at least one of a washing machine and a washer-dryer combo.

[0184] Technical effects of the above embodiments:

[0185] 1. By mixing foam and water, the fluidity of the foam is effectively increased while maintaining a certain degree of fineness, which is more conducive to spraying and dispensing.

[0186] 2. By controlling the on / off switch and ratio of foaming water and mixed water, different foam concentrations can be controlled, making it suitable for different washing needs.

[0187] 3. The cleaning and sterilization rates can be further improved by pre-coating with ultra-concentrated foam.

[0188] 4. The generated ozone foam can be mixed with water and pressurized through an ejector, and then sprayed from the top of the washing drum onto the fabric surface. The foam quickly covers the fabric, providing good sterilization, cleaning, softening, and colorfastness protection.

[0189] It has at least one of the following characteristics:

[0190] 1. A washing machine that utilizes foam to enhance the washing effect, which can control at least two foam states, such as concentrated foam and diluted foam, by adjusting the ratio of detergent to water or the mixing ratio of foam to water.

[0191] 2. Using washing water containing detergent, foaming is achieved through methods such as aeration, suction, and water flow impact. The generated foam is mixed with another stream of water through a mixing device to dilute the foam and increase its pressure and fluidity before being introduced into the washing drum.

[0192] 3. By controlling the on / off state and on / off ratio of foaming water inlet and mixing water inlet, the control of concentrated foam, dilute foam, and freely adjustable foam state can be achieved.

[0193] 4. Furthermore, the concentration of foaming detergent and the water content of foam (foam concentration) can be controlled by controlling the detergent addition time and the foaming water inlet time.

[0194] 5. An ozone generator and air pump can be installed to introduce ozone gas while foaming, so that it adheres to the surface of the foam film and is wrapped inside the foam to form a high-concentration ozone foam, which has good sterilization, enhanced cleaning, softening and colorfastness prevention effects.

[0195] 6. By pre-preparing a concentrated detergent solution, the user can select an ultra-concentrated foam pre-coating method to apply foam pre-coating to localized stains on the fabric. After setting a set time, the fabric can be washed.

[0196] In the above embodiments of this application, the descriptions of each embodiment have their own emphasis. Parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments. The steps illustrated in the related flowcharts can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown here. In other words, the order of steps described in the foregoing embodiments is merely an example. Reasonable adjustments to the order of steps based on the content of the embodiments of this application are also within the protection scope of the embodiments of this application.

[0197] In one specific implementation of this application embodiment, the fabric treatment equipment and foam control method include the following:

[0198] like Figure 3 As shown, taking a drum washing machine as an example, the main system components related to the foam washing function of this washing machine include detergent dispensing and water inlet system 1, ozone foam generating system 2, and treatment tank 3.

[0199] The detergent dispensing and water inlet system 1 includes a foaming water inlet pipe 11 (equivalent to the first inlet pipe), which is connected to the automatic detergent dispensing device 16 for automatic detergent dispensing; a mixing water inlet pipe 12 (equivalent to the second inlet pipe), which is connected to the foam / water mixer 26 (equivalent to the mixer) for mixing foam and water; a spray water inlet pipe 13, which is connected to the second spray head 210 for spraying water into the door seal folds; and a manual dispensing inlet pipe 14, which is connected to the manual detergent dispensing device 15 for manual detergent dispensing.

[0200] The ozone foam generating system consists of an air pump 21, an ozone generator 22, a one-way valve 23, an ozone inlet pipe 24, a foam generator 25, a foam / water mixer 26, a first foam delivery pipeline 27, a second foam delivery pipeline 28, and a first spray head 29.

[0201] The washing drum consists of components such as a water storage tank 31, a treatment tank 32, and a door seal 33.

[0202] The water entering through the foaming water inlet pipe 11 is mixed with the detergent in the detergent automatic dispensing device 16 to form detergent-containing washing water, which is then transported to the foam generator 25 to generate ozone foam. After that, the foam is mixed with the water entering through the mixed water inlet pipe 12 via the foam / water mixer 26 to dilute the foam and increase its pressure and fluidity. Finally, the foam is introduced into the washing drum through the first spray head 29.

[0203] like Figure 4As shown, the foam generator 25 can adopt the aeration foaming method. The air pump 21 pumps the outside air into the ozone generator 22 to generate a high concentration of ozone gas, which then enters the foam generator 25 through the one-way valve 23 and the ozone inlet pipe 24.

[0204] like Figure 3 As shown, jet foaming can also be used without the need for an air pump 21. The washing water in the detergent water delivery pipeline 17 passes through the foam generator 25, which is composed of a Venturi jet, and the negative pressure generated by the jet is used to draw in air and foam. An ozone generator 22 and a one-way valve 23 can be installed at the air intake to allow the generated ozone gas to enter the jet and participate in the foaming.

[0205] The purpose of setting up the ozone generator is to introduce ozone gas during foaming, allowing it to adhere to the surface of the foam film and encapsulate within the foam, forming a high-concentration ozone foam with excellent sterilization, enhanced cleaning, softening, and colorfastness prevention effects. Other gases or liquids with sterilization and enhanced cleaning functions can also be used as substitutes, or air alone can be used for foaming, achieving good cleaning and softening effects.

[0206] After ozone foam is prepared, it enters the foam / water mixer 26 through the first foam delivery pipeline 27 and mixes with the clean water in the mixed water inlet pipeline 12 to form dilute foam. Then, it is sprayed onto the fabric in the treatment tank 32 through the second foam delivery pipeline 28 and the first spray head 29.

[0207] Preferably, the foam / water mixer 2 uses a jet method for mixing. The clean water in the mixing water inlet pipe 12 is injected through the nozzle under the action of tap water pressure to form a negative pressure, which absorbs the foam delivered by the first foam delivery pipe 27 from the surrounding air suction chamber, and then mixes and dilutes it.

[0208] like Figure 5 and 6 As shown, by adjusting the ratio of detergent to water, or the mixing ratio of foam to water, at least two foam states, such as thick foam and thin foam, can be controlled.

[0209] Preferably, the foam is prepared first and then mixed with water, and the foam concentration is controlled by controlling the mixing ratio of foam and water.

[0210] Furthermore, the foam is prepared from foaming water containing detergent. When using an aeration foaming scheme, the flow rate of the foaming water should be less than the flow rate of the mixed water to reduce the foaming water pressure, making it easier to introduce air and foam. At the same time, increasing the mixed water pressure is more conducive to the jet intake of foam. The ratio of the rated flow rate of the foaming water to the rated flow rate of the mixed water (flow rate when the valve is normally open) should be controlled between 1:1 and 1:10.

[0211] After running the foam wash program, the user can choose the foam setting themselves, or the washing machine can recommend a suitable foam setting by detecting information such as the weight and material of the fabric to be washed. Foam settings include at least two types: thick foam and thin foam. Further options may include extra-thick foam and adjustable foam.

[0212] The states of concentrated foam and dilute foam are defined by the ratio of gas volume content to liquid volume content in the foam, calculated by volume. Concentrated foam has a higher gas content and a lower liquid content compared to dilute foam.

[0213] Preferably, the gas-liquid volume ratio of dilute foam is set at 1:10 to 2:1, and the gas-liquid volume ratio of concentrated foam is set at 2:1 to 10:1.

[0214] The method to achieve concentrated foam is as follows: start the foaming water intake, stop the mixing water intake, and simultaneously add detergent. After the detergent is mixed and dissolved, it enters the foam generator to generate foam. Without mixing with clean water, it is directly sprayed into the washing drum to start the drum washing.

[0215] The method for achieving diluted foam is as follows: start the foaming water inlet, start the mixing water inlet, and simultaneously add detergent. After the detergent is mixed and dissolved, it enters the foam generator to generate foam. After mixing with clean water, it is sprayed into the washing drum to start the drum washing.

[0216] The method for achieving freely adjustable foam is as follows: foaming water or mixed water is turned on intermittently while detergent is added. After the detergent is mixed and dissolved, it enters the foam generator to foam. After being mixed with clean water, it is sprayed into the washing drum to start the drum washing.

[0217] To increase foam concentration, increase the foaming water ratio (and increase detergent dosage accordingly) or decrease the mixing water ratio.

[0218] To reduce foam concentration, reduce the foaming water ratio (and reduce the detergent dosage accordingly) or increase the mixing water ratio.

[0219] In another embodiment, the ratio of detergent dosage to foaming water and mixed water is adjusted, specifically by controlling the detergent dosing time T0 and the foaming water inlet time T1. Increasing the detergent dosing time and decreasing the foaming water inlet time can increase the foam concentration, and vice versa.

[0220] In particular, by increasing the ratio of detergent to foaming water, a high-concentration detergent-water mixture can be formed for foaming, producing super-concentrated foam, thereby providing a foam pre-coating washing program.

[0221] Specifically, the foam pre-coating program is run, the ultra-concentrated foam state is set, and the ratio of detergent to water is controlled by controlling the detergent addition time T0 and the foaming water inlet time T1.

[0222] Preferably, the ratio of detergent to water is between 1:10 and 1:1. Since the water volume is relatively small, it is difficult to achieve effective jet aeration; therefore, an aeration foaming method is preferable for preparing the foam.

[0223] When the user selects "Start Foam Pre-coating", the air pump starts, introducing gas into the foam generator for aeration and foaming. The generated foam is then sprayed out from the nozzle. Preferably, the nozzle is positioned in the middle above the washing drum door seal, with the spray direction angled inwards towards the inside of the drum.

[0224] The user manually pre-coats the soiled area of ​​the fabric with high-concentration foam by pointing the foam nozzle at the area to be washed. Then, the fabric is placed in the washing drum and the door is closed. The drum is left to stand, allowing sufficient time for the pre-coated high-concentration foam to act on the stain without being diluted by the wash water. The settling time (T3) should be controlled between 1 and 15 minutes.

[0225] After the settling time is over, the washing machine detects the weight of the fabric to determine whether detergent needs to be added and the appropriate amount, and then starts washing with water.

[0226] Preferably, ozone gas is introduced during the foaming process, causing it to adhere to the surface of the foam film and encapsulate the inside of the foam, forming a high-concentration ozone foam, which has good antibacterial, enhanced cleaning, softening, and colorfastness-preventing effects.
