Description

Technical Field

[0001] The present application relates to the field of fabric processing equipment, and in particular, to a fabric processing equipment and a foam control method. Background Art

[0002] Fabric treatment equipment refers to equipment that can wash loads such as fabrics, shoes and hats. It is an indispensable electrical appliance in the current home. During the use of fabric treatment equipment, detergent is added. The detergent can not only improve the cleanliness of the load, but also generate foam. The foam can play a better role in cleaning and kneading. However, the current fabric treatment equipment relies on stirring the mixture of detergent and water to generate foam, which is difficult to meet the foam treatment needs of different fabrics and reduces the washing effect. Summary of the invention

[0003] The embodiments of the present application provide a fabric processing device and a foam control method to at least solve the technical problem of poor washing effect.

[0004] According to a first aspect of an embodiment of the present application, a fabric processing device is provided, the fabric processing device comprising a processing barrel, an automatic detergent dispensing device, a foam generator, a mixer, a first water inlet pipeline, a second water inlet pipeline, a detergent water delivery pipeline, a first foam delivery pipeline, and a second foam delivery pipeline, wherein:

[0008] The mixer is also provided with a second liquid inlet, which is connected to the water supply end of the second water inlet pipeline to provide mixed water mixed with the foam liquid to the foam liquid introduced into the mixer to dilute the foam liquid, and the second water inlet pipeline is provided with a second control valve; the second control valve can be used to control the water inflow of the mixed water mixed with the foam liquid;

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

[0010] By adopting this embodiment, the mixed water of the second water inlet pipe and the foam liquid output by the foam generator can be mixed in the mixer, so that by changing the ratio between the mixed water and the foam liquid entering the mixer, the condition of the foam liquid entering the fabric treatment chamber can be freely changed, such as changing the foam content in the foam liquid entering the fabric treatment chamber, the fluidity of the foam liquid, etc., so that the fabric in the fabric treatment chamber can obtain the required foam liquid, thereby improving the washing effect.

[0011] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the fabric processing device is provided with a controller, and the controller is configured to control the first control valve and the second control valve according to the load characteristics of the fabric processing device 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] By adopting 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, has a high degree of automation and is conducive to improving the washing effect of the load.

[0013] In combination with the first aspect, in an optional implementation of the embodiment of the present application, controlling the first control valve and the second control valve according to the load characteristics of the fabric processing device so that the foam liquid transported into the fabric processing chamber by the second foam delivery pipeline meets the foam processing demand of the load includes:

[0014] The on-off and / or on-off rhythm 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 provided to the load meets the foam processing requirements, and the foam processing requirements include at least one of the concentration, fluidity and fineness of the foam.

[0015] With this embodiment, at least one of the concentration, fluidity and fineness of the foam can be changed, so that the foam liquid entering the fabric treatment chamber is more likely to meet the requirements of the load, thereby improving the washing effect of the load.

[0016] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the foaming gas supply device is an ozone supply device, and the foam generator generates foam using ozone provided by the ozone supply device.

[0017] According to this embodiment, ozone is used to generate foam, so that the foam can sterilize the load after contacting the load, which helps to improve the washing effect of the load.

[0018] According to a second aspect of an embodiment of the present application, there is provided a foam control method for the above-mentioned fabric processing device, the method comprising:

[0019] obtaining a foam processing requirement, wherein the foam processing requirement includes a foam state of the foam provided to the processing barrel;

[0020] During the operation of the foam generator, the liquid inlet of the first water inlet pipeline and the second water inlet pipeline is controlled according to the foam processing requirement, so that the foam liquid provided to the processing barrel meets the foam processing requirement.

[0021] According to this embodiment, a foam generator is provided on the fabric treatment device. When foam needs to be provided to the treatment barrel, the foam generator can be directly controlled to provide foam to the treatment barrel, without relying on the treatment barrel to stir the mixed liquid of detergent and water to generate foam. The amount of foam is increased and the time node for providing foam can be flexibly controlled, which is conducive to providing sufficient foam for the load in the treatment barrel and making the load fully contact with the foam, thereby improving the washing effect. At the same time, the mixed water in the second water inlet pipeline and the foam liquid output by the foam generator can be mixed in the mixer, so that by changing the ratio between the mixed water and the foam liquid entering the mixer, the situation of the foam liquid entering the fabric treatment chamber can be freely changed, such as changing the foam content in the foam liquid entering the fabric treatment chamber, the fluidity of the foam liquid, etc., so that the fabric in the fabric treatment chamber can obtain the required foam liquid, thereby improving the washing effect.

[0022] In combination with the second aspect, in an optional implementation of the embodiment of the present application, the foam state includes at least one of the concentration, fluidity and fineness of the foam;

[0023] The controlling the liquid inflow of the first water inlet pipeline and the second water inlet pipeline according to the foam processing requirement includes:

[0024] According to the size of at least one of the foam states, the first water inlet pipeline is controlled to supply liquid and a first liquid inlet parameter of the first water inlet pipeline is determined, or the first water inlet pipeline and the second water inlet pipeline are controlled to supply liquid and the first liquid inlet parameter and the second liquid inlet parameter of the second water inlet pipeline are determined.

[0025] By adopting the present implementation method, while adopting different liquid inlet methods, corresponding liquid inlet parameters will also be determined, so that when at least one of the required foam concentration, fluidity and fineness is different, the liquid inlet parameters will also be different, which is conducive to providing foam in different states and improving the washing effect.

[0026] In combination with the second aspect, in an optional implementation of the embodiment of the present application, controlling the liquid inlet into the first water inlet pipeline and determining a first liquid inlet parameter of the first water inlet pipeline, or controlling the liquid inlets into the first water inlet pipeline and the second water inlet pipeline and determining the first liquid inlet parameter and the second liquid inlet parameter of the second water inlet pipeline according to the size of at least one of the foam states, includes:

[0027] If the concentration exceeds the preset target concentration parameter, the first water inlet pipeline is controlled to flow liquid, otherwise the first water inlet pipeline and the second water inlet pipeline are controlled to flow liquid,

[0028] Or, if the fluidity exceeds a preset target flow parameter, the first water inlet pipeline and the second water inlet pipeline are controlled to flow liquid, otherwise the first water inlet pipeline is controlled to flow liquid,

[0029] Alternatively, if the fineness exceeds a preset target fineness parameter, the first water inlet pipeline is controlled to inlet liquid, otherwise the first water inlet pipeline and the second water inlet pipeline are controlled to inlet liquid.

[0030] By adopting this implementation method, the concentration characterizing the foam treatment demand is compared with the target concentration parameter to determine which liquid inlet method to use, so that the process of determining the liquid inlet method is simple and convenient, with a small amount of calculation, which is easy to reduce the occupation of computing resources and reduce computing costs.

[0031] In conjunction with the second aspect, in an optional implementation of the embodiment of the present 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 time, a first flow rate, and a foaming water inlet concentration, and the second liquid inlet parameter includes at least one of a second liquid inlet time and a second flow rate;

[0032] The determining of the first liquid inlet parameter of the first water inlet pipeline includes:

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

[0034] The determining of the first liquid inlet parameter and the second liquid inlet parameter of the second water inlet pipeline includes:

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

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

[0037] In combination with the second aspect, in an optional implementation of the embodiment of the present application, the foam state includes thick foam and thin foam, wherein the concentration of the thick foam is greater than the concentration of the thin foam;

[0038] The controlling the liquid inflow of the first water inlet pipeline and the second water inlet pipeline according to the foam processing requirement includes:

[0039] If the foam treatment requirement indicates that the foam required is the concentrated foam, controlling the first water inlet pipeline to flow liquid and closing the second water inlet pipeline;

[0040] If the foam treatment requirement indicates that the foam required is the thin foam, the first water inlet pipeline and the second water inlet pipeline are controlled to inlet liquid.

[0041] By adopting this implementation method, by directly setting the states of concentrated foam and thin foam, it is directly determined whether to use the first water inlet pipeline or the first water inlet pipeline and the second water inlet pipeline to inject liquid at the same time, which simplifies the steps of determining the liquid injection method, helps to improve the efficiency of providing foam to the processing barrel, reduce the amount of calculation, and reduce the calculation cost.

[0042] In conjunction with the second aspect, in an optional implementation of the embodiment of the present application, the foam state also includes a custom concentration state;

[0043] The controlling the liquid inflow of the first water inlet pipeline and the second water inlet pipeline according to the foam processing requirement includes:

[0044] If the foam treatment requirement represents that the foam required is in a custom concentration state, the first water inlet pipeline and the second water inlet pipeline are controlled to intermittently supply liquid according to the preset first opening and closing cycle, or the second opening and closing cycle is obtained and the first water inlet pipeline and the second water inlet pipeline are controlled to intermittently supply liquid according to the second opening and closing cycle.

[0045] By adopting this implementation method, the concentration state can also be customized, and the liquid inlet of the first water inlet pipeline and the second water inlet pipeline can be controlled by intermittent liquid inlet, which is conducive to meeting the needs of users and improving the user experience of the fabric processing equipment.

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

[0047] The greater the concentration of foam required by the foam processing requirement representation, the longer the detergent dispensing time of the automatic detergent dispensing device is controlled and / or the shorter the foaming water inlet time of the automatic detergent dispensing device is controlled;

[0048] The smaller the foam concentration required by the foam processing requirement representation, the shorter the detergent dispensing time of the automatic detergent dispensing device is controlled and / or the longer the foaming water inlet time of the automatic detergent dispensing device is controlled.

[0049] By adopting this implementation, the concentration of foam entering the treatment barrel can be changed by adjusting the detergent addition time and / or water inlet time, thereby improving the flexibility of foam concentration adjustment.

[0050] In conjunction with the second aspect, in an optional implementation of the embodiment of the present application, obtaining the foam processing requirement includes:

[0051] Obtaining the weight and / or material of fabric in the processing barrel;

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

[0053] By adopting this implementation method, the foam processing requirement is determined according to the fabric weight and / or fabric material, so that the foam processing requirement is more closely matched with the actual foam processing requirement of the fabric in the treatment barrel, which helps to improve the washing effect of the fabric.

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

[0055] In response to the pre-coating signal, obtaining a pre-coating requirement, wherein the pre-coating requirement represents a required concentration of super-concentrated foam;

[0056] Controlling the first water inlet pipe to enter the foaming water inlet and adjusting the detergent dispensing time of the automatic detergent dispensing device and / or the foaming water inlet time of the automatic detergent dispensing device according to the pre-coating requirement, wherein the greater the concentration of the super-concentrated foam required by the pre-coating requirement, the greater the detergent dispensing time and / or the shorter the foaming water inlet time;

[0057] The foam generator is controlled to output foam liquid to the processing barrel.

[0058] By adopting the present implementation method, when it is necessary to pre-coat the fabric with foam, the liquid inlet of the first water inlet pipe is directly controlled and the detergent addition time and / or the foaming water inlet time are adjusted, so that the fabric in the treatment barrel can obtain super-concentrated foam in advance before washing, which is beneficial to increase the contact time between the foam and the fabric, thereby improving the washing effect of the fabric.

[0059] According to a third aspect of an embodiment of the present application, a control method for a fabric processing device is provided, which adopts the foam control method described above.

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

[0061] In response to a pre-coating signal, determining whether the foam generator outputs foam liquid to the processing barrel;

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

[0063] With this implementation, when pre-coating foam, the target time will be waited for, and then the processing barrel will be controlled to rotate, which is beneficial 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 an embodiment of the present application, a fabric processing device is provided, which adopts the foam control method described above or adopts the control method described above.

[0067] The foam outlet of the liquid processing module is connected to the processing barrel, and is used to process the washing water containing detergent to generate foam to obtain foam liquid, and transport the processed foam liquid to the processing barrel;

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

[0069] By adopting this implementation mode, the liquid processing module can process the mixed liquid to generate foam, so that the mixed liquid entering the processing barrel contains foam, so that the load is in contact with the foam earlier, thereby improving the washing effect.

[0070] In combination with the fourth aspect, in an optional implementation of the embodiment of the present application, the liquid processing module includes an ozone generator and a foam generator, the liquid inlet of the foam generator is connected to the water supply end of the liquid inlet module, and the foam outlet of the foam generator is connected to the fabric processing chamber of the processing barrel;

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

[0072] By adopting this implementation, the ozone generator can transport ozone into the foam generator, so that the foam entering the treatment barrel contains ozone. After the ozone contacts the load, it can be sterilized, thereby improving the washing effect.

[0073] In combination with the fourth aspect, in an optional implementation of the embodiment of the present application, the fabric processing device includes at least one of a washing machine and a washer-dryer.

[0081] In order 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 in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0082] It should be understood that the "plurality" mentioned in this article refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and so on are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and so on do not limit the quantity and execution order, and the words "first", "second" and so on do not limit certain different

[0083] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0084] Detergent foam can play a good role in cleaning and softening fabrics during washing. Currently, existing washing machines usually do not have active foam generating devices, 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.

[0085] In addition, in terms of healthy sterilization, gases such as ozone, which have good sterilization effects, are difficult to dissolve in water and cannot play a good sterilization role during the washing process. However, they can adhere to the surface of the foam and wrap inside the foam, achieving a good sterilization effect during the contact between the foam and the fabric. However, the existing foam washing has not been fully combined with the sterilization function, and only focuses on the washing effect.

[0086] In addition, during the application of foam washing in washing machines, problems such as foam fineness, foam water content and fluidity control need to be solved.

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

[0088] 1. It solves the problems of foam fineness, water content (foam concentration) and fluidity control in ozone foam washing of washing machines.

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

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

[0091] Next, the fabric processing device provided in the embodiments of the present application is described in detail.

[0092] A fabric processing device, the fabric processing device comprises a processing barrel, a detergent automatic dispensing device, a foam generator, a mixer, a first water inlet pipeline, a second water inlet pipeline, a detergent water delivery pipeline, a first foam delivery pipeline and a second foam delivery pipeline, wherein:

[0093] The water supply end of the first water inlet pipeline is connected to the water inlet of the automatic detergent dispensing device to 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 end of the detergent water delivery pipeline, and the other end of the detergent water delivery pipeline is connected to the liquid inlet of the foam generator; a first control valve is provided on the first water inlet pipeline, which can be used to control the water inlet amount of the foaming water;

[0095] The air inlet of the foam generator is communicated with the foaming gas supply device, the foam outlet is communicated with the inlet end of the first foam delivery pipeline, and the outlet end of the first foam delivery pipeline is communicated with the first liquid inlet of the mixer to provide the 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 pipeline to provide mixed water mixed with the foam liquid to the foam liquid introduced into the mixer to dilute the foam liquid. The second water inlet pipeline is provided with a second control valve; the second control valve can be used to control the water inflow of the mixed water mixed with the foam liquid;

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

[0098] In one embodiment, detergent can be stored in the automatic detergent dispensing device, and the first water inlet pipe can be connected to a tap, so that tap water enters the automatic detergent dispensing device as foaming water and mixes with the detergent to become washing water. Since the washing water contains detergent, foam can be generated to obtain foam liquid. When started, the detergent in the automatic detergent dispensing device can be manually or automatically put in, and this embodiment does not specifically limit this.

[0099] The mixer can mix the foam liquid with the mixing water, so that the proportion of water in the foam liquid is increased, thereby diluting the foam liquid. When the proportion of the mixing water to the foam liquid before dilution is different, the foam concentration and fluidity of the diluted foam liquid will also be different.

[0100] By adopting this embodiment, the mixed water of the second water inlet pipe and the foam liquid output by the foam generator can be mixed in the mixer, so that by changing the ratio between the mixed water and the foam liquid entering the mixer, the condition of the foam liquid entering the fabric treatment chamber can be freely changed, such as changing the foam content in the foam liquid entering the fabric treatment chamber, the fluidity of the foam liquid, etc., so that the fabric in the fabric treatment chamber can obtain the required foam liquid, thereby improving the washing effect.

[0101] In combination with the first aspect, in an optional implementation of an embodiment of the present application, the fabric processing device is provided with a controller, and the controller is configured to control the first control valve and the second control valve according to the load characteristics of the fabric processing device 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, the load characteristics include characteristics that can 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 processing requirements of the load are likely to be different. For example, for materials that are not easy to absorb foam, such loads require a larger amount of foam.

[0103] By adopting 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, has a high degree of automation and is conducive to improving the washing effect of the load.

[0104] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the first control valve and the second control valve are controlled according to the load characteristics of the fabric processing device so that the foam liquid transported into the fabric processing chamber by the second foam delivery pipeline meets the foam processing demand of the load, including:

[0105] The on-off and / or on-off rhythm 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 provided to the load meets the foam processing requirements, and the foam processing requirements include at least one of the concentration, fluidity and fineness of the foam.

[0106] In one embodiment, the material is, for example, cotton, linen, etc., and the stain characteristics include the type of stain, such as oil, dust, etc. Different on-off conditions, different on-off beats, and different on-off durations can change the ratio of mixed water to the foam liquid before dilution, so that the foam state of the foam liquid entering the fabric treatment chamber changes to meet the foam treatment requirements.

[0107] With this embodiment, at least one of the concentration, fluidity and fineness of the foam can be changed, so that the foam liquid entering the fabric treatment chamber is more likely to meet the requirements of the load, thereby improving the washing effect of the load.

[0108] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the foaming gas supply device is an ozone supply device, and the foam generator generates foam using ozone provided by the ozone supply device.

[0109] According to this embodiment, ozone is used to generate foam, so that the foam can sterilize the load after contacting the load, which helps to improve the washing effect of the load.

[0110] The present application embodiment provides a foam control method for the above-mentioned fabric processing equipment, referring to Figure 1 The schematic flow chart of the foam control method for fabric processing equipment shown in the figure includes the following processing procedures.

[0111] S100, obtaining foam processing requirements.

[0112] The foam processing requirements include the foam state of the foam provided to the processing barrel, such as the amount of foam, the concentration of foam, and the fluidity of the foam when entering the processing barrel.

[0113] S102. During the operation of the foam generator, the liquid inlet of the first water inlet pipeline and the second water inlet pipeline is controlled according to the foam processing requirement, so that the foam liquid provided to the processing barrel meets the foam processing requirement.

[0114] Specifically, the first water inlet pipeline is controlled to feed liquid according to the foam processing requirement, or the first water inlet pipeline and the second water inlet pipeline are controlled to feed liquid according to the foam processing requirement.

[0115] In one embodiment, different foam treatment requirements require different liquid inlet methods, including a first liquid inlet method for controlling liquid inlet into the first water inlet pipeline and a second liquid inlet method for controlling liquid inlet into both the first water inlet pipeline and the second water inlet pipeline.

[0116] It should be noted that, since the first water inlet pipeline and the second water inlet pipeline output different liquids and the output positions of the liquids are also different, the state of the foam entering the processing barrel will be changed.

[0117] According to this embodiment, a foam generator is provided on the fabric treatment device. When foam needs to be provided to the treatment barrel, the foam generator can be directly controlled to provide foam to the treatment barrel, without relying on the treatment barrel to stir the mixed liquid of detergent and water to generate foam. The amount of foam is increased and the time node for providing foam can be flexibly controlled, which is conducive to providing sufficient foam for the load in the treatment barrel and making the load fully contact with the foam, thereby improving the washing effect. At the same time, the mixed water in the second water inlet pipeline and the foam liquid output by the foam generator can be mixed in the mixer, so that by changing the ratio between the mixed water and the foam liquid entering the mixer, the situation of the foam liquid entering the fabric treatment chamber can be freely changed, such as changing the foam content in the foam liquid entering the fabric treatment chamber, the fluidity of the foam liquid, etc., so that the fabric in the fabric treatment chamber can obtain the required foam liquid, thereby improving the washing effect.

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

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

[0120] According to the size of at least one of the foam states, the first water inlet pipeline is controlled to feed liquid and a first inlet parameter of the first water inlet pipeline is determined, or the first water inlet pipeline and the second water inlet pipeline are controlled to feed liquid and a first inlet parameter and a second inlet parameter of the second water inlet pipeline are determined.

[0121] In one embodiment, the concentration may be represented by a concentration value or a concentration level, which is not specifically limited in this embodiment.

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

[0123] The fluidity can reflect the fluidity of the foam. In one embodiment, the fluidity can be represented by the ratio of the foam volume to the water intake volume. Specifically, the greater the foam volume, the smaller the fluidity, and the greater the water intake volume, the greater the fluidity.

[0124] Fineness can reflect the stability of the foam, the size of the foam and the uniformity of the foam size. Specifically, the size of the foam and the uniformity of the foam size are related to the model of the foam generator, and the stability of the foam is related to the amount of foam and the amount of water intake. Among them, the larger the amount of foam, the smaller the stability, and the larger the amount of water intake, the greater the stability.

[0125] Since the concentration, fluidity and fineness of the foam are at least related to the amount of foam and the amount of water inlet, the foam state can be changed by changing the foaming water inlet conditions of the first water inlet pipeline and the water inlet conditions of the second water inlet pipeline.

[0126] With this embodiment, while adopting different liquid inlet methods, corresponding liquid inlet parameters will also be determined, so that when at least one of the required foam concentration, fluidity and fineness is different, the liquid inlet parameters will also be different, which is conducive to providing foam in different states and improving the washing effect.

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

[0128] If the concentration represented by the foam treatment demand exceeds the preset target concentration parameter, the first water inlet pipeline is controlled to flow liquid, otherwise the first water inlet pipeline and the second water inlet pipeline are controlled to flow liquid,

[0129] Or, if the foam flowability required by the foam treatment requirement characterization exceeds the preset target flow parameter, the first water inlet pipeline and the second water inlet pipeline are controlled to flow liquid, otherwise the first water inlet pipeline is controlled to flow liquid,

[0130] Alternatively, if the fineness of the foam required by the foam processing requirement characterization exceeds a preset target fineness parameter, the first water inlet pipeline is controlled to feed liquid, otherwise the first water inlet pipeline and the second water inlet pipeline are controlled to feed liquid.

[0131] In one embodiment, since the concentration may be a concentration value or a concentration level, when pre-setting the target concentration parameters, the corresponding concentration may be set. Specifically, the target concentration parameters include 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, a greater concentration level indicates a greater foam concentration.

[0133] By adopting this implementation method, the concentration state characterized by the foam treatment demand is compared with the target concentration parameter to determine which liquid inlet method to use, so that the process of determining the liquid inlet method is simple and convenient, with a small amount of calculation, which is easy to reduce the occupation of computing resources and reduce computing costs.

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

[0135] Determining a first liquid inlet parameter of a first water inlet pipeline includes:

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

[0137] Determining a first liquid inlet parameter and a second liquid inlet parameter of a second water inlet pipeline includes:

[0138] 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.

[0139] In one embodiment, the first liquid inlet time refers to the time it takes for the foaming water to enter the foam generator, and the first flow rate refers to the flow rate of the foaming water; the second liquid inlet time refers to the time it takes for the water in the second water inlet pipe to enter the path, and the second flow rate refers to the flow rate of the water in the second water inlet pipe.

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

[0141] Optionally, in an implementation of this embodiment, the foam state includes thick foam and thin foam, wherein the concentration of the thick foam is greater than the concentration of the thin foam;

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

[0143] If the foam treatment requirement indicates that the foam required is concentrated foam, the first water inlet pipeline is controlled to flow liquid and the second water inlet pipeline is closed;

[0144] If the foam treatment requirement indicates that the foam required is thin foam, the first water inlet pipeline and the second water inlet pipeline are controlled to inlet liquid.

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

[0146] In addition, it should be noted that in other embodiments, as long as the first liquid inlet method is adopted, the second water inlet pipeline is controlled to be closed.

[0147] By adopting this implementation method, by directly setting the states of concentrated foam and thin foam, it is directly determined whether to use the first water inlet pipeline or the first water inlet pipeline and the second water inlet pipeline to inject liquid at the same time, which simplifies the steps of determining the liquid injection method, helps to improve the efficiency of providing foam to the processing barrel, reduce the amount of calculation, and reduce the calculation cost.

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

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

[0150] If the foam treatment requirement represents that the required foam is in a custom concentration state, the first water inlet pipeline and the second water inlet pipeline are controlled to intermittently supply liquid according to the preset first opening and closing cycle, or the second opening and closing cycle is obtained and the first water inlet pipeline and the second water inlet pipeline are controlled to intermittently supply liquid according to the second opening and closing cycle.

[0151] By adopting this implementation method, the concentration state can also be customized, and the liquid inlet of the first water inlet pipeline and the second water inlet pipeline can be controlled by intermittent liquid inlet, which is conducive to meeting the needs of users and improving the user experience of the fabric processing equipment.

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

[0153] The foam treatment demand characterization requires that the greater the concentration of foam required, the greater the detergent dispensing time of the automatic detergent dispensing device is, and / or the shorter the foaming water inlet time of the automatic detergent dispensing device is;

[0154] The foam processing demand indicates that the smaller the required foam concentration is, the shorter the detergent dispensing time of the automatic detergent dispensing device is and / or the longer the foaming water inlet time of the automatic detergent dispensing device is.

[0155] By adopting this implementation, the concentration of foam entering the treatment barrel can be changed by adjusting the detergent addition time and / or water inlet time, thereby improving the flexibility of foam concentration adjustment.

[0156] Optionally, in an implementation of this embodiment, obtaining the foam processing requirement includes:

[0157] obtaining the weight and / or material of fabric in the treatment bucket;

[0158] Determine foam treatment requirements based on fabric weight and / or fabric material.

[0159] In one embodiment, a relationship table is preset, and the relationship table includes fabric weight and / or fabric material and / or fabric dirtiness. Different fabric weights and / or fabric materials and / or fabric dirtiness correspond to different foam processing requirements. When the foam processing requirements need to be determined, the foam processing requirements corresponding to the obtained fabric weight and / or fabric material and / or fabric dirtiness can be found in the relationship table. The fabric dirtiness can be obtained by detecting the transparency of the fabric or the turbidity of the washing water, which is not specifically limited in this embodiment.

[0160] By adopting this implementation method, the foam processing requirement is determined according to the fabric weight and / or fabric material, so that the foam processing requirement is more closely matched with the actual foam processing requirement of the fabric in the treatment barrel, which helps to improve the washing effect of the fabric.

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

[0162] In response to the pre-coating signal, obtaining a pre-coating requirement, wherein the pre-coating requirement represents a required concentration of the super-concentrated foam;

[0163] Controlling the first water inlet pipe to enter the foaming water inlet and adjusting the detergent dispensing time of the automatic detergent dispensing device and / or the foaming water inlet time of the automatic detergent dispensing device according to the pre-coating demand, wherein the greater the concentration of the super-concentrated foam required by the pre-coating demand, the greater the detergent dispensing time and / or the shorter the foaming water inlet time;

[0164] The foam generator is controlled to output foam liquid to the processing barrel.

[0165] In one embodiment, when the fabric needs to be pre-coated with foam, a pre-coating signal is generated. The pre-coating signal may be generated after the user selects the pre-coating button of the fabric treatment device, or may be generated by the fabric treatment device according to the setting of the operating program selected by the user, which is not specifically limited in this embodiment.

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

[0167] By adopting the present implementation method, when it is necessary to pre-coat the fabric with foam, the liquid inlet of the first water inlet pipe is directly controlled and the detergent addition time and / or the foaming water inlet time are adjusted, so that the fabric in the treatment barrel can obtain super-concentrated foam in advance before washing, which is beneficial to increase the contact time between the foam and the fabric, thereby improving the washing effect of the fabric.

[0168] The embodiment of the present application also provides a control method for a fabric processing device, which adopts the above-mentioned foam control method.

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

[0170] In response to the pre-coating signal, determining whether the foam generator outputs foam liquid to the processing barrel;

[0171] If so, after the foam generator finishes outputting the foam liquid, the processing barrel is controlled to rotate after waiting for a preset target time.

[0172] With this implementation, when pre-coating foam, the target time will be waited for, and then the processing barrel will be controlled to rotate, which is beneficial to increase the contact time between the foam and the fabric, thereby improving the washing effect of the fabric.

[0173] An embodiment of the present application provides a fabric processing device, which adopts the above-mentioned foam control method or the above-mentioned control method.

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

[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 barrel, and is used to process the washing water containing detergent to generate foam to obtain foam liquid, and then transport the processed foam liquid to the processing barrel;

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

[0178] By adopting this implementation mode, the liquid processing module can process the mixed liquid to generate foam, so that the mixed liquid entering the processing barrel contains foam, so that the load is in contact with the foam earlier, thereby improving the washing effect.

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

[0180] The ozone generator is used to deliver ozone to the foam generator.

[0181] By adopting this implementation, the ozone generator can transport ozone into the foam generator, so that the foam entering the treatment barrel contains ozone. After the ozone contacts the load, it can be sterilized, thereby improving the washing effect.

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

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

[0184] The technical effects of the above embodiments are as follows:

[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.

[0186] 2. By controlling the switch and proportion of foaming water and mixed water, different foam concentrations can be controlled to meet different washing needs.

[0187] 3. The cleaning rate and sterilization rate can be further improved through pre-coating of super-concentrated foam.

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

[0189] Have at least one of the following characteristics:

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

[0191] 2. Use washing water containing detergent to generate foam through aeration, air suction, water flow impact, etc. The generated foam is mixed with another water through a mixing device to dilute the foam and increase the pressure and fluidity, and then passed into the washing drum.

[0192] 3. By controlling the start and stop status and the start and stop ratio of foaming water inlet and mixed water inlet, the control of thick foam, thin foam and free adjustment of foam state can be achieved.

[0193] 4. Furthermore, the concentration of the foaming detergent and the water content of the foam (the thickness and thinness of the foam) can be controlled by controlling the time for adding the detergent and the time for the foaming water to enter.

[0194] 5. An ozone generator and an air pump can be set up to introduce ozone gas during 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 with good sterilization, enhanced cleaning, softening and anti-color transfer effects.

[0195] 6. Prepare concentrated detergent water in advance, and the user can choose to pre-coat the local stains on the fabric with foam, and then wash after it is left to stand for a set time.

[0196] In the above-mentioned embodiments of the present application, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. The steps shown in the relevant flow chart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of steps described in the foregoing embodiments is only an example, and it is also within the scope of protection of the embodiments of the present application to reasonably adjust the order of steps based on the content of the embodiments of the present application.

[0197] In a specific implementation of the embodiment of the present application, the fabric processing device and the foam control method include the following contents:

[0198] like Figure 3 As shown, taking a drum washing machine as an example, the system components related to the foam washing function of the washing machine mainly include a detergent delivery and water inlet system 1, an ozone foam generating system 2, a processing barrel 3, etc.

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

[0200] The ozone foam generating system is composed of an air pump 21 , an ozone generator 22 , a one-way valve 23 , an ozone air 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 tub is composed of a water storage tub 31 , a treatment tub 32 , a door seal 33 and other components.

[0202] The water entering the foaming water inlet pipe 11 is mixed with the detergent in the automatic detergent dispensing device 16 to form washing water containing detergent, which is then transported to the foam generator 25. After generating ozone foam, the water is mixed with the water entering the mixing water inlet pipe 12 through the foam / water mixer 26 to dilute the foam and increase the pressure and fluidity, and then enters the washing tub through the first spray head 29.

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

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

[0205] The purpose of the ozone generator is to introduce ozone gas during foaming, so that it adheres to the surface of the foam film and wraps inside the foam, forming a high-concentration ozone foam with good sterilization, enhanced cleaning, softening and anti-coloring effects. It can also be replaced by other gases or liquids with sterilization, enhanced cleaning and other functions, or only air is used for foaming, which can also play a good cleaning and softening role.

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

[0207] Preferably, the foam / water mixer 2 adopts a jet method for mixing, and the clean water in the mixed water inlet pipe 12 forms a negative pressure through the nozzle jet under the action of tap water pressure, absorbs the foam delivered by the first foam delivery pipe 27 from the surrounding suction cavity, 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, i.e., thick foam and thin foam, can be controlled.

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

[0210] Furthermore, the foam is prepared by foaming water containing detergent. When the aeration foaming scheme is adopted, the foaming water flow rate should be smaller than the mixed water flow rate, so as to reduce the foaming water pressure, make it easier to inlet air and foam, and increase the mixed water pressure at the same time, which is more conducive to the jet inhalation of foam. The ratio of the rated flow rate of foaming water to the rated flow rate of mixed water (the flow rate when the valve is normally open) should be controlled between 1:1 and 1:10.

[0211] After running the foam washing program, the user can select the foam state by himself, or the washing machine can recommend a suitable foam state by detecting the weight, material and other information of the fabric to be washed. The foam state includes at least two types: thick foam and thin foam. Furthermore, it can also include super thick foam, free adjustable foam and other states.

[0212] The states of dense foam and thin foam are defined by the ratio of the gas volume content to the liquid volume content in the foam calculated by volume, wherein dense foam has a higher gas content and a lower liquid content than thin foam.

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

[0214] The method of achieving concentrated foam is to develop water for foaming, close water for mixing, and add detergent at the same time. After the detergent is mixed and dissolved, it enters the foam generator for foaming, does not mix with clean water, and is directly sprayed into the washing drum to start rotary washing.

[0215] The implementation method of dilute foam is to develop water for foaming, start mixing water for mixing, and add detergent at the same time. After the detergent is mixed and dissolved, it enters the foam generator for foaming, and after mixing with clean water, it is sprayed into the washing drum to start drum washing.

[0216] The method of freely adjusting the foam is that the foaming water or the mixed water is turned on intermittently and the detergent is added at the same time. After the detergent is mixed and dissolved, it enters the foam generator for foaming, and after mixing with the clean water, it is sprayed into the washing drum to start the drum washing.

[0217] If you want to increase the foam concentration, increase the foaming water opening ratio (increase the detergent dosage simultaneously) or reduce the mixing water opening ratio.

[0218] If you want to reduce the foam concentration, reduce the foaming water opening ratio (the amount of detergent added is reduced simultaneously) or increase the mixing water opening ratio.

[0219] In another embodiment, the ratio of the amount of detergent added to the foaming water and the mixed water can be adjusted by controlling the detergent addition time T0 and the foaming water inlet time T1. Increasing the detergent addition time and reducing the foaming water inlet time can increase the foam concentration, and vice versa, reduce the foam concentration.

[0220] In particular, by increasing the dosage ratio of detergent to foaming water, a high-concentration detergent water is mixed and foamed to produce super-concentrated foam, thereby providing a foam pre-coating washing procedure.

[0221] Specifically, the foam pre-coating program is run, the super-concentrated foam state is set, and the detergent and water addition ratio 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 amount of water is small and it is difficult to jet aspiration, it is appropriate to adopt an aeration foaming scheme to prepare the foam.

[0223] When the user selects "start foam pre-coating", the air pump starts, and gas is introduced into the foam generator for aeration and foaming, and the generated foam is sprayed out from the nozzle. Preferably, the nozzle is set in the middle position above the washing drum door seal, and the spray direction is inclined toward the drum.

[0224] The user aligns the local dirty part of the fabric to be washed with the foam nozzle, manually pre-applies high-concentration foam, and then puts the fabric into the washing drum and closes the door. The washing drum is left to stand, so that the pre-applied high-concentration foam has sufficient time to act on the stains without being diluted by the washing water. The standing time T3 should be controlled within 1-15 minutes.

[0225] After the standing time is over, the washing machine detects the weight of the fabric to determine whether detergent needs to be added and the corresponding amount, and then fills the water drum for washing.

[0226] Preferably, ozone gas is introduced during the foaming process to adhere to the surface of the foam film and wrap inside the foam to form high-concentration ozone foam, which has good sterilization, enhanced cleaning, softening and anti-color transfer effects.
