[0088] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0089] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0090] According to an embodiment of the present application, an embodiment of a fabric care method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0091] Example 1

[0092] like Figure 1 、 2As shown in , 6 and 7, the fabric care method provided in the embodiments of the present application is applied to a fabric processing device, such as a washing and care machine, the fabric processing device includes a fabric processing drum 4, a first steam generator 5 and a second steam generator 6, wherein the first steam generator 5 conveys steam from the first direction of the fabric processing drum 4 into the fabric processing drum 4, and the second steam generator 6 conveys steam from the second direction of the fabric processing drum 4 to the fabric processing drum 4, the first direction and the second direction are different directions, such as the first direction is from top to bottom, and the second direction is from bottom to top.

[0093] The method provided in this embodiment includes:

[0094] S101, obtaining material information of the fabric to be processed;

[0095] In one embodiment, the fabric to be treated refers to the fabric that needs to be cared for. The fabric to be treated can be the fabric that is put into the fabric treatment drum 4 for a separate fabric care procedure, or it can be the fabric to be treated that needs to enter the steam care stage after completing the dehydration procedure. This embodiment does not make specific limitations on this.

[0096] It should be noted that the fabric to be processed can be a top, or it can be pants, underwear, shirts, suits, furs and other types of clothing. This embodiment does not make specific restrictions on this. The material type of the fabric can be different material types such as knitted silk, chemical fiber, wool, etc.

[0097] Specifically, in one embodiment of the present application, material information refers to the material of the fabric, such as cotton, linen, chemical fiber, wool, silk, shirts, suits, mink, etc., which is not specifically limited in this embodiment. It should be noted that when classifying materials, the purpose is to classify materials with different moisture absorption difficulties into different categories. Therefore, fabrics made of the same material but with different production methods can be classified into different categories, so that different control schemes are obtained when controlling the first steam generator 5 and the second steam generator 6 based on the material information. For ease of understanding, for example, fabric A is knitted and fabric B is woven. Due to the different production methods, fabrics A and B have different moisture absorption difficulties. In this case, fabrics A and B can be classified into different material categories. For example, fabric A is wool a, and fabric B is wool b. The specific method of distinguishing them is not specifically limited in this embodiment. In other words, the material information in this embodiment includes clothing type and material type. This is mainly because different clothing types have different moisture absorption difficulties, and different material types also have different moisture absorption difficulties. Therefore, the material information covers both.

[0098] In one embodiment, the material information of the fabric to be processed can be obtained through user input or automatic identification. For example, the user can interact with a button or an interactive screen on the fabric processing device to input the material of the fabric to be processed, thereby obtaining the material information of the fabric to be processed. In another example, the fabric processing device may be equipped with a mechanism such as a camera or sensor capable of identifying the material of the fabric to be processed, and the material information of the fabric to be processed can be obtained by obtaining the identification results of such mechanism.

[0099] S102 , alternately operating the first steam generator 5 and the second steam generator 6 in a preset steam care stage of fabric care, and controlling the alternating operating time ratio of the first steam generator 5 and the second steam generator 6 based on the material information.

[0100] For fabrics of different materials to be treated, the alternating operating time ratio of the first steam generator 5 and the second steam generator 6 varies. Specifically, fabric care can include multiple stages. During the predetermined steam care stage, care is performed by alternating the operation of the first steam generator 5 and the second steam generator 6. During other stages of fabric care, only one steam generator or both steam generators can be activated simultaneously.

[0101] The alternating operation time ratio refers to the ratio of the time the first steam generator 5 is in the start-up state to the total duration of the preset steam care stage and the ratio of the time the second steam generator 6 is in the start-up state to the total duration of the preset steam care stage.

[0102] Preferably, the preset steam care phase occurs before the drying phase.

[0103] Preferably, the preset steam care stage and the drying stage are started simultaneously, and the drying is performed after the steam care stage ends.

[0104] Through the above content, by obtaining the material information of the fabric to be treated, the alternating operation time ratio is determined in the stage of alternating operation of the first steam generator 5 and the second steam generator 6, so that fabrics to be treated of different materials can obtain different steam delivery methods within the same care time, which helps to ensure that fabrics to be treated of different material types can receive corresponding steam care, thereby improving the care effect.

[0105] Preferably, the first steam generator 5 is arranged at the upper part of the fabric processing barrel, and the second steam generator 6 is arranged at the lower part of the fabric processing barrel, and the directions in which the steam is ejected by the two are opposite to each other (of course, it is not required to be completely opposite). Further preferably, the second steam generator 6 may not be a heating device separately provided for steam care. We can cleverly use the washing water heating device provided at the lower part of the fabric processing barrel to achieve steam humidification, so that the setting of the second steam generator 6 can achieve multiple goals at one stroke. In terms of steam care method, the steam care of this application can be provided with the option of a mode of alternating operation of two steam generators and different proportions of alternating operation can be selected according to the material type of the fabric, so that the steam care method provided in this embodiment is more flexible and diverse and can be well adapted to the steam care needs of different clothing types and material types.

[0106] Preferably, in another embodiment of the present application, controlling the alternating operation time ratio of the first steam generator 5 and the second steam generator 6 based on the material information includes:

[0107] The greater the moisture absorption difficulty of the fabric to be treated represented by the material information, the relatively longer the operating time of the second steam generator 6 is controlled, and the relative operating time ratio of the second steam generator 6 and the first steam generator 5 is controlled. That is to say, the greater the moisture absorption difficulty of the fabric to be treated, the longer the operating time of the second steam generator 6 is controlled, and the relative operating time ratio of the second steam generator 6 and the first steam generator 5 is greater.

[0108] Preferably, the second steam generator 6 is more likely to deliver steam to the fabric to be treated than the first steam generator 5, or the steam volume of the second steam generator 6 is larger, or the steam of the second steam generator 6 is easier for the fabric to be treated to absorb. Therefore, by increasing the operating time ratio of the second steam generator 6, it is easy to improve the care effect and efficiency.

[0109] In another embodiment of the present application, Figure 2 As shown, the above control method also includes:

[0110] S201 detects the moisture content of the fabric during the alternating operation of the first steam generator 5 and the second steam generator 6;

[0111] S202: adjusting the rotation speed of the fabric processing drum 4 in real time according to the moisture content to adapt to the moisture content.

[0112] The moisture content status can be realized by detecting the moisture content of the fabric to be processed. Specifically, the moisture content status can be detected by detecting the weight or by using a humidity sensor.

[0113] By adapting the rotation speed of the fabric treatment drum 4 to its moisture content, the fabric is driven to rotate within the fabric treatment drum 4. Fabrics with different moisture contents follow different rotational paths within the fabric treatment drum 4. Adjusting the rotation speed of the fabric treatment drum 4 allows fabrics with corresponding moisture contents to stretch when tossed within the fabric treatment drum 4, thereby increasing the steam absorption area of ​​the treated fabric, thereby increasing steam absorption and ensuring a superior care effect for the treated fabric.

[0114] Preferably, the higher the moisture content represented by the detected moisture content state, the smaller the control speed.

[0115] Specifically, the fabric to be treated will rotate along with the inner drum during care. By adjusting the rotation speed of the fabric treatment drum 4, the fabric to be treated can be stretched and thrown at different moisture contents. Figure 7 As shown, the fabric to be treated can be driven by the lifting ribs 41 from the bottom of the drum to the range of 120° to 180° for spreading and stretching each time, and the fabric to be treated will not be rolled up in the range of 0° to 90°. Each fabric to be treated can be well spread and draw a parabolic state, which is conducive to better absorption of steam and water mist and smoothing of wrinkles. Among them, the rotation axis of the fabric treatment drum 4 is a horizontal line, that is, the opening of the fabric treatment drum 4 is located at the front side, and the center of the longitudinal section of the fabric treatment drum 4 is used as the coordinate origin. An extension line is drawn vertically downward from the center of the circle. This extension line serves as the basic coordinate axis. It rotates counterclockwise, and the angle increases from 0 to 180 degrees, reaching the top position of the drum.

[0116] When the moisture content of clothing is high, it becomes heavier, and a higher rotation speed makes it easier for it to stick to the wall, while a lower rotation speed allows it to be spread out more effectively. As the moisture content decreases, the weight decreases, and at a higher rotation speed, it will not stick to the wall and will be spread out more easily. Therefore, as the moisture content decreases, the rotation speed will gradually increase, ensuring that the fabric being treated is always in a relatively good spreading state.

[0117] As an optional embodiment of the first steam generator 5 and the second steam generator 6 of the above embodiment of the present application, the first steam generator 5 is a main steam generator, and the second steam generator 6 is an auxiliary steam generator, which delivers steam to the fabric processing drum 4 from a first direction of the fabric processing drum 4, that is, from the upper part of the fabric processing drum 4 to the lower part of the fabric processing drum 4, and delivers steam to the fabric processing drum 4 from a second direction of the fabric processing drum 4, that is, from the lower part of the fabric processing drum 4 to the upper part of the fabric processing drum 4;

[0118] Based on the above-mentioned embodiment of the first steam generator 5 and the second steam generator 6, in another embodiment of the present application, the method further includes:

[0119] In the preset steam care stage of alternately operating the first steam generator 5 and the second steam generator 6 , the first steam generator 5 is started first and then the second steam generator 6 is started.

[0120] By activating the first steam generator 5 first, the water droplets generated by the first steam generator 5 can be easily dropped to the position of the second steam generator 6. This eliminates the need to actively provide water to the second steam generator 6, which can also generate steam, thereby improving the convenience of care and saving water resources. In addition, the second steam generator 6 is located at the bottom, which facilitates the steam to be absorbed by the fabric to be treated, thereby improving the care effect by extending the activation time of the second steam generator 6.

[0121] It should be noted that after the water droplets dropped from the first steam generator 5 reach the position of the second steam generator 6, they accumulate at the position of the second steam generator 6 and the height gradually increases. The height of the accumulated water in the second steam generator 6 is not lower than the height of the second steam generator 6, and is also not higher than the height of the lower end of the fabric treatment drum 4 (taking the washing machine as an example, it is not higher than the height of the gap between the inner drum and the outer drum), to prevent the accumulated water from entering the fabric treatment drum 4. If the height of the accumulated water is lower than the heating tube, the heating tube will be exposed to the air and dry-burned and damaged. If the height of the accumulated water is higher than the height of the gap between the inner and outer drums, the water at the bottom of the drum will directly enter the drum and wet the clothes, causing the clothes to be overly wet and difficult to dry.

[0122] Furthermore, when the first steam generator 5 and the second steam generator 6 are operated alternately, the water temperature is used to determine whether steam is being generated and the duration of steam generation, thereby controlling the on and off of the first steam generator 5 and the second steam generator 6. For example, when it is necessary to switch to the second steam generator 6, the first steam generator 5 is turned off, and the second steam generator 6 is then started. The temperature of the water heated by the second steam generator 6 is obtained, and when the water temperature reaches 100 degrees Celsius, the timer starts. When the time reaches the current on time of the second steam generator 6, the second steam generator 6 is turned off.

[0123] In another embodiment of the present application, the second steam generator 6 also has a wash water heating function. This eliminates the need for a separate steam generator and allows the washing and heating equipment already located below the fabric treatment tub to be directly utilized to easily implement a flexible and diverse steam care method that can adapt to the care needs of different materials. This not only improves the care effect, but also reduces the amount of hardware, saving internal space and cost of the fabric treatment equipment.

[0124] Example 2

[0125] like Figure 3 、 4As shown in FIG. 7 , in another embodiment of the present application, a fabric care method is provided. The method in this embodiment is applied to a fabric treatment device, which includes a fabric treatment drum 4, a first steam generator 5, and a second steam generator 6. The first steam generator 5 delivers steam into the fabric treatment drum 4 from a first direction of the fabric treatment drum 4, and the second steam generator 6 delivers steam into the fabric treatment drum 4 from a second direction of the fabric treatment drum 4, wherein the first direction and the second direction are different directions. The method includes:

[0126] S701, obtaining material information of the fabric to be processed;

[0127] In one embodiment, the fabric to be treated refers to the fabric that needs to be cared for. The fabric to be treated can be the fabric put into the fabric treatment drum 4 after the fabric treatment equipment runs the care program, or it can be the fabric left in the fabric treatment drum 4 after the fabric treatment equipment runs the washing program.

[0129] In one embodiment, the material information refers to the material of the fabric, such as cotton, linen, chemical fiber, wool, silk, shirts, suits, mink, etc., which is not specifically limited in this embodiment. It should be noted that when classifying the materials, the purpose is to classify materials with different moisture absorption difficulties into different categories. Therefore, fabrics with the same material but different production methods can be divided into different categories, so that when the first steam generator 5 and the second steam generator 6 are controlled according to the material information, different control schemes are obtained. For ease of understanding, for example, fabrics are both made of wool material, fabric A is knitted, and fabric B is woven. Due to the different production methods, the moisture absorption difficulty of fabric A and fabric B is different. At this time, the materials of fabric A and fabric B can be divided into different categories. For example, the material of fabric A belongs to wool a, and the material of fabric B belongs to wool b. The specific method of distinction is not specifically limited in this embodiment.

[0130] In one embodiment, the material information of the fabric to be processed can be obtained through user input or automatic identification. For example, the user can interact with a button or an interactive screen on the fabric processing device to input the material of the fabric to be processed, thereby obtaining the material information of the fabric to be processed. In another example, the fabric processing device may be equipped with a mechanism such as a camera or sensor capable of identifying the material of the fabric to be processed, and the material information of the fabric to be processed can be obtained by obtaining the identification results of such mechanism.

[0131] S702 : Determine the operation strategies of the first steam generator 5 and the second steam generator 6 according to the material information.

[0132] The operation strategy includes an operation mode of the first steam generator 5 and the second steam generator 6; the operation modes include a separate operation mode in which only one of the first steam generator 5 and the second steam generator 6 is operated, a combined operation mode in which the first steam generator 5 and the second steam generator 6 are operated simultaneously, and an alternating operation mode in which the first steam generator 5 and the second steam generator 6 are operated alternately.

[0133] Preferably, the first steam generator 5 is the primary steam generator. That is, when fabric care is required, the first steam generator 5 is prioritized for generating steam to humidify the fabric being treated, thereby increasing its moisture content. The second steam generator 6 is the auxiliary steam generator, activated only when needed to generate steam and humidify the fabric being treated. Therefore, since different materials have different moisture absorption properties, if the fabric being treated is difficult to absorb steam, the second steam generator 6 can be activated to improve its steam absorption. This generates operating modes, specifically, a single operation mode, a combined operation mode, and an alternating operation mode. When the second steam generator 6 is activated, how long it is activated, and how it cooperates with the first steam generator 5 to generate steam can all be determined by the operating strategy after the operating mode is determined.

[0134] That is to say, an operating strategy for the second steam generator 6 can be preset for each material. After obtaining the material information of the fabric to be processed, the preset operating strategy is searched according to the material information of the fabric to be processed to obtain the corresponding operating strategy, so as to determine a care method corresponding to the material of the fabric to be processed, thereby improving the care effect of the fabric to be processed.

[0135] S703: Control the first steam generator 5 and the second steam generator 6 according to the operation strategy to care for the fabric to be treated.

[0136] After the operating strategy is determined, the first steam generator 5 and / or the second steam generator 6 can be controlled according to the control method for the second steam generator 6 in the operating strategy, so that steam enters the fabric treatment drum 4, and the steam is absorbed by the fabric to be treated, so that the moisture content of the fabric to be treated is increased, which facilitates wrinkle removal of the fabric to be treated, thereby achieving care for the fabric to be treated.

[0137] It should be noted that when the operation strategy is that when the nursing program runs for a preset time, such as 1 minute, only the second steam generator 6 is operated. When this time node is reached, the first steam generator 5 needs to be turned off, so that the second steam generator 6 runs alone.

[0138] To facilitate understanding, the control process is described by taking an example.

[0139] For example, if the operation strategy is to turn off the second steam generator 6 and keep it in the off state (i.e., the single operation mode), then when steam is supplied to the fabric treatment drum 4 according to the operation strategy, only the first steam generator 5 will be controlled, so that the first steam generator 5 generates steam and flows into the fabric treatment drum 4.

[0140] For another example, the operation strategy is to turn on the second steam generator 6 and only turn on the second steam generator 6 (i.e., the combined operation mode). At this time, according to the operation strategy, only the second steam generator 6 will be controlled so that the second steam generator 6 generates steam and flows into the fabric processing drum 4.

[0141] For another example, the operation strategy is determined as alternating operation of the first steam generator 5 and the second steam generator 6. For example, after the first steam generator 5 finishes running, the second steam generator 6 starts running, and after the second steam generator 6 finishes running, the first steam generator 5 is started again to run, thus the two alternately operate in a mode.

[0142] The present application also provides a further embodiment, in which the two operate alternately as follows: the first steam generator 5 ends its operation for a first preset time interval (for example, 1 minute) and then the second steam generator 6 starts to operate; the second steam generator 6 ends its operation for a second preset time interval (for example, 30 seconds) and then the first steam generator 5 is restarted. That is to say, after one of the steam generators stops running, the other steam generator does not start immediately, but is restarted after a certain period of time, so that the steam can provide sufficient care for the fabric.

[0143] Through the above-mentioned improvements, the embodiment of the present application obtains the material information of the fabric to be treated, determines the operation strategy, and the operation strategy includes three operation modes, so that fabrics to be treated of different materials can receive different care methods within the same care time, which helps to improve the humidification effect of the fabric to be treated, thereby improving the care effect.

[0144] In another embodiment of the present application, determining the operation strategy of the first steam generator 5 and the second steam generator 6 according to the material information includes:

[0145] Determining the moisture absorption difficulty of the fabric to be treated according to the material information of the fabric to be treated;

[0146] The operation mode of the first steam generator 5 and the second steam generator 6 is determined according to the moisture absorption difficulty of the fabric to be treated.

[0147] The moisture absorption difficulty is used to characterize whether the treated fabric of the corresponding material easily absorbs steam. Specifically, the moisture absorption difficulty can be determined based on the total amount of steam that can be absorbed by the fabric of different materials and the steam absorption efficiency. For example, for a material with a large total amount of steam absorption and high absorption efficiency, the moisture absorption difficulty can be determined as easy to absorb, while for a material with a small total amount of steam absorption and low absorption efficiency, the moisture absorption difficulty can be determined as difficult to absorb. For materials with a large total amount of steam absorption but low absorption efficiency, or materials with a small total amount of steam absorption but high absorption efficiency, the moisture absorption difficulty can be determined to be between easy to absorb and difficult to absorb. In other words, this embodiment does not specifically limit how to grade the moisture absorption difficulty or how many levels it is divided into.

[0148] Since the moisture absorption difficulty can be determined once the material is determined, a pre-set material-situation relationship table can be used. After obtaining the material information of the fabric to be processed, the moisture absorption difficulty can be retrieved from the relationship table based on the material to be processed. The operating mode can then be determined based on the moisture absorption difficulty.

[0149] Specifically, for example, by presetting a situation-strategy relationship table, after obtaining the moisture absorption difficulty of the fabric to be processed, the operation mode is retrieved from the relationship table according to the moisture absorption difficulty, thereby obtaining the operation strategy.

[0150] Through the above content, different operating modes correspond to the materials to be treated with different moisture absorption difficulties, which helps to carry out targeted care for the fabrics to be treated and improve the care effect.

[0151] In another embodiment of the present application, the material information includes a material type;

[0152] The greater the wrinkle-removing moisture content value required for the material type, the more difficult it is to characterize moisture absorption.

[0153] Specifically, the material types include cotton, linen, chemical fiber, wool, silk, shirts, suits, mink, etc. Different types of fabrics to be treated require different wrinkle removal moisture content values, and the larger the wrinkle removal moisture content value, the more difficult it is to determine the moisture absorption of the fabric to be treated.

[0154] Specifically, for example,

[0155] Material Type Optimal moisture content for wrinkle removal Cotton and linen 26％ chemical fiber 28％ Type 1 wool 21％ silk 35％ pure cotton 23％ Class II wool 6％ mink 15％

[0156] The material type of the fabric to be treated is silk, and the required wrinkle removal moisture content value is the largest, which is 35%. Therefore, for the material type of the fabric to be treated is silk, it is the most difficult to determine the moisture absorption of the fabric to be treated.

[0157] It should be noted that pure cotton fabrics, such as shirts, and Class II wool fabrics, such as suits, differ from Class I wool fabrics in that suits require less water absorption and require a lower moisture content during care. Therefore, suits are assigned the material type of Class II wool, while other wool fabrics are assigned the material type of Class I wool. The optimal wrinkle-removing moisture content refers to the target moisture content required for care of each material type. In other words, during care, the moisture content of the corresponding material type should be increased to the optimal wrinkle-removing moisture content as much as possible. Therefore, the optimal wrinkle-removing moisture content is a fixed value that can be preset.

[0158] Through the above content, determining the moisture absorption difficulty according to the desired wrinkle removal moisture content value helps to improve the fit between the moisture absorption difficulty and the actual situation, thereby improving the reliability of the determined moisture absorption difficulty.

[0159] In another embodiment of the present application, Figure 4 As shown, the operation modes of the first steam generator 5 and the second steam generator 6 are determined according to the moisture absorption difficulty of the fabric to be treated, including:

[0160] S1001, if the moisture absorption difficulty satisfies a first preset condition, controlling the first steam generator 5 or the second steam generator 6 to operate independently in an independent operation mode;

[0161] S1002: If the moisture absorption difficulty satisfies a second preset condition, controlling the first steam generator 5 and the second steam generator 6 to operate in a combined operation mode;

[0162] S1003: If the moisture absorption difficulty satisfies a third preset condition, the first steam generator 5 and the second steam generator 6 are controlled to operate alternately in an alternating operation mode.

[0163] The first preset condition, the second preset condition, and the third preset condition can be a numerical range or a level range. For example, if the moisture absorption difficulty is expressed in levels, the first preset condition corresponds to the corresponding level range. If the moisture absorption difficulty is within the level range, the first preset condition is satisfied, and the first steam generator 5 or the second steam generator 6 is controlled to operate independently in the independent operation mode. The second and third preset conditions are similar and will not be described in detail.

[0164] Through the above content, the operation mode is determined by using preset conditions, which is conducive to reducing the amount of calculation and saving computing resources.

[0165] In another embodiment of the present application,

[0166] When the first steam generator 5 or the second steam generator 6 is controlled to operate independently in the independent operation mode:

[0167] Controlling the first steam generator 5 and the second steam generator 6 according to the operation strategy to care for the fabric to be treated includes:

[0168] Controlling the operating time and / or steam flow of the first steam generator 5 or the second steam generator 6 that operates independently;

[0169] When the first steam generator 5 and the second steam generator 6 are controlled to operate separately in the combined operation mode:

[0170] Controlling the first steam generator 5 and the second steam generator 6 according to the operation strategy to care for the fabric to be treated includes:

[0171] The operation timing and / or operation duration and / or steam flow rate of the first steam generator 5 and the second steam generator 6 in joint operation are controlled.

[0172] Through the above content, different operating modes have different considerations, which are conducive to improving the care effect of the treated fabric in the corresponding operating mode.

[0173] In another embodiment of the present application, when the first steam generator 5 or the second steam generator 6 is controlled to operate alternately in an alternating operation mode, the fabric care includes n alternating operation cycles of the first steam generator 5 and the second steam generator 6, the operation duration of the first steam generator 5 in each alternating cycle is T1i, the operation duration of the second steam generator 6 is T2i, and the operation frequency of each alternating cycle is 1 / Ti=1 / (T1i+T2i);

[0174] Controlling the first steam generator 5 and the second steam generator 6 to deliver steam to the fabric treatment drum 4 according to the operation strategy to care for the fabric to be treated includes:

[0175] In the preset steam care stage of fabric care, the operating frequency 1 / Ti of the first steam generator 5 and the second steam generator 6 in alternating operation and the alternating operation time ratio T2i / T1i of each operation cycle are controlled, n≥1, i∈[1,n];

[0176] The preset steam care phase for fabric care takes place before the drying process.

[0177] In another embodiment of the present application, the greater the moisture absorption difficulty represented by the material information, the greater the T2i / T1i ratio, and the longer the relative running time of T2i.

[0178] Through the above content, the steam of the second steam generator 6 moves from bottom to top and is more easily absorbed by the fabric to be treated. By extending the operating time of the second steam generator 6, it is beneficial to treat the fabric to be treated that is more difficult to absorb, so as to improve the care effect and efficiency of the fabric to be treated.

[0179] In another embodiment of the present application, the first steam generator 5 is a main steam generator, and the second steam generator 6 is an auxiliary steam generator, which delivers steam to the fabric processing drum 4 from a first direction of the fabric processing drum 4, that is, from the upper part of the fabric processing drum 4 to the lower part of the fabric processing drum 4, and delivers steam to the fabric processing drum 4 from a second direction of the fabric processing drum 4, that is, from the lower part of the fabric processing drum 4 to the upper part of the fabric processing drum 4.

[0180] According to the above content, the second steam generator 6 is located at the bottom, which is conducive to the steam being absorbed by the fabric to be treated, thereby improving the care effect by extending the opening time of the second steam generator 6.

[0181] In another embodiment of the present application, the second steam generator 6 also has a washing water heating function.

[0182] Through the above content, the second steam generator 6 has other functions, which improves the functionality of the second steam generator 6, reduces the amount of hardware, and is conducive to saving the internal space and cost of the fabric processing equipment.

[0183] In another embodiment of the present application, the method further comprises:

[0184] During the alternating operation of the first steam generator 5 and the second steam generator 6, the moisture content of the fabric is detected;

[0185] The rotation speed of the fabric processing drum 4 is adjusted in real time according to the moisture content to adapt to the moisture content.

[0186] In another embodiment of the present application, the higher the water content represented by the detected water content state, the smaller the control speed.

[0187] As described above, the fabric is driven to rotate by the fabric treatment drum 4 while in the fabric treatment drum 4. Fabrics with different moisture contents follow different rotational paths within the fabric treatment drum 4. By adjusting the rotational speed of the fabric treatment drum 4, fabrics with corresponding moisture contents can be stretched when tossed in the fabric treatment drum 4. This increases the steam absorption area of ​​the treated fabric, thereby increasing the steam absorption capacity and ensuring a good care effect for the treated fabric.

[0188] Example 3

[0189] In another embodiment of the present application, a fabric care method is also provided. Figure 5 and 7As shown, the method in this embodiment is applied to a fabric processing device, which includes a fabric processing drum 4, a first steam generator 5, and a second steam generator 6. The first steam generator 5 delivers steam from a first direction into the fabric processing drum 4, and the second steam generator 6 delivers steam from a second direction into the fabric processing drum 4. The first direction and the second direction are different directions. The method includes:

[0190] S1801. Obtain material information of the fabric to be processed.

[0191] In one embodiment, the fabric to be treated refers to the fabric that needs to be cared for. The fabric to be treated can be the fabric put into the fabric treatment drum 4 after the fabric treatment equipment runs the care program, or it can be the fabric left in the fabric treatment drum 4 after the fabric treatment equipment runs the washing program. This embodiment does not make specific limitations on this.

[0192] It should be noted that the fabric to be processed can be a top, or can be trousers, underwear, shoes, etc., and this embodiment does not make any specific limitation to this.

[0193] In one embodiment, the material information refers to the material of the fabric, such as cotton, linen, chemical fiber, wool, silk, shirts, suits, mink, etc., which is not specifically limited in this embodiment. It should be noted that when classifying the materials, the purpose is to classify materials with different moisture absorption difficulties into different categories. Therefore, fabrics with the same material but different production methods can be divided into different categories, so that when the first steam generator 5 and the second steam generator 6 are controlled according to the material information, different control schemes are obtained. For ease of understanding, for example, fabrics are both made of wool material, fabric A is knitted, and fabric B is woven. Due to the different production methods, the moisture absorption difficulty of fabric A and fabric B is different. At this time, the materials of fabric A and fabric B can be divided into different categories. For example, the material of fabric A belongs to wool a, and the material of fabric B belongs to wool b. The specific method of distinction is not specifically limited in this embodiment.

[0194] In one embodiment, the material information of the fabric to be processed can be obtained through user input or automatic identification. For example, the user can interact with a button or an interactive screen on the fabric processing device to input the material of the fabric to be processed, thereby obtaining the material information of the fabric to be processed. In another example, the fabric processing device may be equipped with a mechanism such as a camera or sensor capable of identifying the material of the fabric to be processed, and the material information of the fabric to be processed can be obtained by obtaining the identification results of such mechanism.

[0195] S1802 : Determine an operation strategy for the first steam generator 5 and the second steam generator 6 according to the material information. The operation strategy includes an operation time ratio when the first steam generator 5 and the second steam generator 6 operate alternately.

[0196] It should be noted that the first steam generator 5 is the main steam generator. That is, when fabric care is required, the first steam generator 5 is given priority to generate steam to humidify the fabric to be treated to increase its moisture content. The second steam generator 6 is an auxiliary steam generator. Only when it is needed is the second steam generator 6 started to generate steam to humidify the fabric to be treated. Therefore, since different materials have different moisture absorption difficulties, if the material of the fabric to be treated is difficult to absorb steam, the second steam generator 6 can be started to increase the steam absorption of the fabric to be treated. When the second steam generator 6 is started, how long it is started, and how it cooperates with the first steam generator 5 to generate steam can all be determined by the operating strategy.

[0197] That is to say, an operating strategy for the second steam generator 6 can be preset for each material. After obtaining the material information of the fabric to be processed, the preset operating strategy is searched according to the material information of the fabric to be processed to obtain the corresponding operating strategy, so as to determine a care method corresponding to the material of the fabric to be processed, thereby improving the care effect of the fabric to be processed.

[0198] S1803: Control the first steam generator 5 and the second steam generator 6 according to the operation strategy to care for the fabric to be treated.

[0199] After the operating strategy is determined, the first steam generator 5 and / or the second steam generator 6 can be controlled according to the control method for the second steam generator 6 in the operating strategy, so that steam enters the fabric treatment drum 4, and the steam is absorbed by the fabric to be treated, so that the moisture content of the fabric to be treated is increased, which facilitates wrinkle removal of the fabric to be treated, thereby achieving care for the fabric to be treated.

[0200] It should be noted that when the operation strategy is that when the nursing program runs for 1 minute, only the second steam generator 6 is operated. When this time node is reached, the first steam generator 5 needs to be turned off, so that the second steam generator 6 runs alone.

[0201] To facilitate understanding, the control process is described using an example. For example, if the operating strategy is to shut down and maintain the second steam generator 6, then when steam is delivered to the fabric treatment drum 4 according to the operating strategy, only the first steam generator 5 will be controlled, causing the first steam generator 5 to generate steam and flow into the fabric treatment drum 4.

[0202] For another example, the operation strategy is to turn on the second steam generator 6 and only turn on the second steam generator 6. At this time, according to the operation strategy, only the second steam generator 6 will be controlled so that the second steam generator 6 generates steam and flows into the fabric processing drum 4.

[0203] For another example, the operation strategy is to turn on the second steam generator 6 for 30 seconds every minute. In this case, according to the operation strategy, both the first steam generator 5 and the second steam generator 6 will be controlled, so that when the second steam generator 6 is turned on, the first steam generator 5 is turned off, and when the second steam generator 6 is turned off, the first steam generator 5 is turned on.

[0204] It should be noted that this embodiment does not specifically limit the locations of the first steam generator 5 and the second steam generator 6. For example, the first steam generator 5 and the second steam generator 6 may both be located on one side of the fabric treatment drum 4, and each may utilize a pipe to introduce steam into the fabric treatment drum 4. In another example, the first steam generator 5 and the second steam generator 6 may be located on different sides of the fabric treatment drum 4, and each may utilize a pipe to introduce steam into the fabric treatment drum 4. Furthermore, the first steam generator 5 may be located above the fabric treatment drum 4, and the second steam generator 6 may be located below the fabric treatment drum 4, eliminating the need for pipes to direct the flow of steam.

[0205] Through the above content, by obtaining the material of the fabric to be treated and changing the operation strategy of the second steam generator 6 according to the material, fabrics to be treated of different materials can obtain different steam delivery strategies within the same care time, which helps to improve the humidification effect of the fabric to be treated, thereby improving the care effect.

[0206] In another embodiment of the present application, the operating time ratio includes a first ratio of the operating time of the first steam generator 5 to the total operating time of the two and a second ratio of the operating time of the second steam generator 6 to the total operating time of the two;

[0207] Determining the operation strategies of the first steam generator 5 and the second steam generator 6 according to the material information includes:

[0208] Determine the moisture absorption difficulty of the fabric to be treated based on the material information;

[0209] A first proportion of the operating time of the first steam generator 5 and a second proportion of the operating time of the second steam generator 6 are determined according to the moisture absorption difficulty, wherein the higher the moisture absorption difficulty is, the larger the second proportion is.

[0210] The moisture absorption difficulty is used to characterize whether the treated fabric of the corresponding material easily absorbs steam. Specifically, the moisture absorption difficulty can be determined based on the total amount of steam that can be absorbed by the fabric of different materials and the steam absorption efficiency. For example, for a material with a large total amount of steam absorption and high absorption efficiency, the moisture absorption difficulty can be determined as easy to absorb, while for a material with a small total amount of steam absorption and low absorption efficiency, the moisture absorption difficulty can be determined as difficult to absorb. For materials with a large total amount of steam absorption but low absorption efficiency, or materials with a small total amount of steam absorption but high absorption efficiency, the moisture absorption difficulty can be determined to be between easy to absorb and difficult to absorb. In other words, this embodiment does not specifically limit how to grade the moisture absorption difficulty or how many levels it is divided into.

[0211] Since the moisture absorption difficulty can be determined once the material is determined, a pre-set material-situation relationship table can be used. Once the material information of the fabric to be processed is obtained, the moisture absorption difficulty can be retrieved from the relationship table based on the material to be processed. The operation strategy can then be determined based on the moisture absorption difficulty.

[0212] Specifically, for example, by presetting a situation-strategy relationship table, after obtaining the moisture absorption difficulty of the fabric to be processed, the operation strategy is retrieved from the relationship table according to the moisture absorption difficulty.

[0213] That is, for fabrics to be treated whose moisture absorption difficulty is easy to absorb, the operating strategy of the second steam generator 6 is determined to be alternating operation with the first steam generator 5, and the on-time of the second steam generator 6 accounts for a first proportion of the total moisture absorption time. For fabrics to be treated whose moisture absorption difficulty is difficult to absorb, the operating strategy of the second steam generator 6 is determined to be alternating operation with the first steam generator 5, and the on-time of the second steam generator 6 accounts for a second proportion of the total moisture absorption time. The first proportion is less than the second proportion.

[0214] In one embodiment, different moisture absorption difficulties can be set to different levels, and different power supply levels represent different absorption difficulties. For example, the higher the level, the greater the difficulty of the fabric of the corresponding material to absorb steam. The higher the level, the greater the proportion of the opening time of the second steam generator 6 in the total time in the determined operation strategy. Specifically, in an application scenario, the levels include one, two, three, four and five. The proportion corresponding to level one is 10%, the proportion corresponding to level two is 20%, the proportion corresponding to level three is 30%, the proportion corresponding to level four is 40%, and the proportion corresponding to level five is 50%. If the material of the fabric to be treated belongs to level three, the determined operation strategy is that the opening time of the second steam generator 6 accounts for 30% of the total time.

[0215] The on-time of the second steam generator 6 refers to the total time that the second steam generator 6 is on during a nursing process. The total time refers to the total time that the first steam generator 5 and the second steam generator 6 are on during a nursing process. The ratio can be calculated as follows:

[0216] Q = t2 / (t1+t2);

[0217] Wherein Q is a ratio, t1 is the opening time of the first steam generator 5 , and t2 is the opening time of the second steam generator 6 .

[0218] Through the above content, as the absorption difficulty increases, the proportion of the opening time of the second steam generator 6 of the determined operation strategy also increases, which helps to use the second steam generator 6 to improve the absorption efficiency of the steam of the fabric to be treated, so that the fabric to be treated reaches the required moisture content within a limited time, thereby improving the care effect of the fabric to be treated.

[0219] Different materials have different difficulties in absorbing moisture from steam. Based on this, the operating strategy of the second steam generator 6 is determined, and the operating strategy includes the on-off control and / or the on-time control of the second steam generator 6, so that for fabrics to be treated of different materials, an operating strategy suitable for the moisture absorption difficulty can be determined, so that the fabrics to be treated can absorb sufficient steam within a limited time, so as to improve the de-wrinkling effect of the fabrics to be treated, and thereby improve the care effect of the fabrics to be treated.

[0220] In another embodiment of the present application, the first steam generator 5 and the second steam generator 6 are controlled according to an operation strategy to perform care on the fabric to be treated, including:

[0221] The first steam generator 5 and the second steam generator 6 are operated alternately in a preset steam care stage of fabric care, and the operating time of the first steam generator 5 and the second steam generator 6 is controlled based on the first ratio and the second ratio to deliver steam to the fabric treatment drum 4 to care for the fabric to be treated, wherein the preset steam care stage occurs before the drying stage.

[0222] Through the above, alternately operating the first steam generator 5 and the second steam generator 6 helps to reduce the energy consumption of the fabric treatment equipment, thereby reducing the care cost.

[0223] In another embodiment of the present application, the preset steam care stage of fabric care includes n alternating operation cycles, the total operation time of the i-th cycle in the n alternating operation cycles is Ti, the operation time of the first steam generator 5 is T1i, the operation time of the second steam generator 6 is T2i, and Ti=T1i+T2i;

[0224] Determining a first proportion of the operating time of the first steam generator 5 and a second proportion of the operating time of the second steam generator 6 according to the moisture absorption difficulty includes:

[0225] T2i is determined based on the difficulty of moisture absorption;

[0226] Determine the second ratio according to T2i / Ti, where Ti is a preset value;

[0227] T1i is determined according to Ti and T2i, and the first proportion is determined according to T1i / Ti, where n≥1, i∈[1,n].

[0228] In another embodiment of the present application, before determining the first proportion of the operating time of the first steam generator 5 and the second proportion of the operating time of the second steam generator 6 according to the moisture absorption difficulty, the method further includes:

[0229] The operating modes of the first steam generator 5 and the second steam generator 6 are determined according to the difficulty of moisture absorption, wherein the operating modes include at least one of the first steam generator 5 operating alone, the first steam generator 5 and the second steam generator 6 operating simultaneously, and the first steam generator 5 and the second steam generator 6 operating alternately. The operating strategy includes controlling the operating modes of the first steam generator 5 and the second steam generator 6. When the operating mode is that the first steam generator 5 and the second steam generator 6 operate alternately, the first proportion of the operating time of the first steam generator 5 and the second proportion of the operating time of the second steam generator 6 are determined according to the difficulty of moisture absorption.

[0230] Through the above content, by obtaining the material information of the fabric to be treated, the operation strategy is determined and the operation strategy includes three operation modes, so that fabrics to be treated of different materials can receive different care methods within the same care time, which helps to improve the humidification effect of the fabric to be treated, thereby improving the care effect.

[0231] In another embodiment of the present application, determining the operating mode of the first steam generator 5 and the second steam generator 6 according to the moisture absorption difficulty includes:

[0232] If the moisture absorption difficulty characterizes that the moisture absorption difficulty is low, the operation mode is determined to be that the first steam generator 5 operates alone;

[0233] If the moisture absorption difficulty characterizes the moisture absorption difficulty as medium, the operation mode is determined to be alternating operation of the first steam generator 5 and the second steam generator 6;

[0234] If the moisture absorption difficulty indicates that the moisture absorption difficulty is high, the operation mode is determined to be that the first steam generator 5 and the second steam generator 6 operate simultaneously.

[0235] Among them, alternating operation means that only one of the first steam generator 5 and the second steam generator 6 is in the on state. That is to say, when the first steam generator 5 is turned on, the second steam generator 6 is turned off, and when the second steam generator 6 is turned on, the first steam generator 5 is turned off. It should be noted that this embodiment does not specifically limit the single on time of the first steam generator 5, the single on time of the second steam generator 6, and the interval time during the alternating operation. Among them, the interval time can be 0 or not. When the interval time is not 0, after the first steam generator 5 switches from the on state to the off state, it waits for the interval time before turning on the second steam generator 6; similarly, after the second steam generator 6 switches from the on state to the off state, it waits for the interval time before turning on the first steam generator 5.

[0236] Through the above content, the alternating operation method helps to reduce the power consumption of the fabric processing equipment during fabric care, avoid tripping due to excessive power and a sharp increase in power consumption caused by simultaneously starting the first steam generator 5 and the second steam generator 6.

[0237] In another embodiment of the present application, the method further comprises:

[0238] Determine the difficulty of moisture absorption according to the type of material.

[0239] Alternatively, the difficulty of moisture absorption can be determined based on the type of material and the target moisture content required for the care of the fabric to be treated.

[0240] In one embodiment, a preset table is used to store the type of material and the moisture absorption difficulty. After obtaining the material information of the fabric to be processed, the corresponding moisture absorption difficulty is searched in the table according to the type represented by the material information, and the moisture absorption difficulty found is used as the moisture absorption difficulty of the fabric to be processed.

[0241] In one embodiment, in addition to the material type, the target moisture content of the fabric being treated is also considered. The target moisture content refers to the target value to which the moisture content of the fabric being treated should be raised. For example, as shown in the table below, a pre-set table is provided containing the material type and the optimal wrinkle-removing moisture content for each type. The optimal wrinkle-removing moisture content is used as the target moisture content. If the fabric being treated is cotton or linen, the target moisture content is 26%; if the fabric being treated is wool, the target moisture content is 21%.

[0242] Nursing Process Model Optimal moisture content for wrinkle removal Cotton and linen 26％ chemical fiber 28％ wool 21％ silk 35％ shirt 23％ suits 6％ mink 15％

[0243] Through the above content, when determining the difficulty of moisture absorption of steam by fabric, the target moisture content can be added as a consideration factor, which helps to improve the rationality of moisture absorption difficulty, so that the operating strategy determined according to each moisture absorption difficulty is convenient for increasing the moisture content of the fabric to the target moisture content, thereby improving the care effect.

[0244] In another embodiment of the present application, the method further comprises:

[0245] During the alternating operation of the first steam generator 5 and the second steam generator 6, the moisture content of the fabric is detected;

[0246] The rotation speed of the fabric processing drum 4 is adjusted in real time according to the moisture content state to adapt to the moisture content state, wherein the higher the moisture content represented by the detected moisture content state, the smaller the rotation speed is controlled.

[0247] The moisture content refers to the current moisture content of the fabric being treated. In one embodiment, the moisture content of the fabric being treated can be detected by providing a weight sensor. For example, the fabric being treated at time t3 is weighed, and the weight is obtained as d1. After a period of time, the fabric being treated at time t4 is weighed, and the weight is obtained as d2. By calculating the difference between d2 and d1, and using a preset difference-moisture content relationship table, the moisture content of the fabric being treated at time t4 can be determined. In another embodiment, the moisture content of the fabric being treated can also be detected by using a humidity sensor, which will not be further described.

[0248] In one embodiment, the preset relationship table includes the moisture content status and the target speed. After knowing the moisture content status, the target speed can be found in the preset relationship table, and then the speed of the fabric processing drum 4 is adjusted to the target speed.

[0249] Among them, the preset relationship table is shown in the following table.

[0250] Moisture content status Target speed / rpm When too dry 58-60 10％ 55-57 20％ 52-54 30％ 49-51 40％ 45-47

[0251] As described above, the fabric is driven to rotate by the fabric treatment drum 4 while in the fabric treatment drum 4. Fabrics with different moisture contents follow different rotational paths within the fabric treatment drum 4. By adjusting the rotational speed of the fabric treatment drum 4, fabrics with corresponding moisture contents can be stretched when tossed in the fabric treatment drum 4. This increases the steam absorption area of ​​the treated fabric, thereby increasing the steam absorption capacity and ensuring a good care effect for the treated fabric.

[0252] In another embodiment of the present application, the second steam generator 6 comprises a heating tube in the fabric treatment device for heating water temperature when washing fabrics, the heating tube is located below the fabric treatment drum 4, and the first steam generator 5 is located above the fabric treatment drum 4.

[0253] In one embodiment, if Figure 7As shown, the fabric treatment device includes a display panel 1, a fabric treatment drum 4, lifting ribs 41, a first steam generator 5, and a heating pipe. A steam pipeline 7 is provided between the first steam generator 5 and the fabric treatment drum 4, and the steam generated by the first steam generator 5 is guided into the fabric treatment drum 4 by the steam pipeline 7.

[0254] The fabric loading port of the fabric treatment drum 4 is located at the front of the fabric treatment apparatus, with the central axis of the fabric treatment drum 4 oriented horizontally. A first steam generator 5 is located above the fabric treatment drum 4, and a heating pipe is located below the fabric treatment drum 4. The first steam generator 5 heats water to generate steam, while the heating pipe acts as a second steam generator 6 to heat the water below the fabric treatment drum 4. The heating pipe heats the water for washing fabrics and heats the water below the fabric treatment drum 4 to generate steam for fabric conditioning.

[0255] It should be noted that, when caring for fabrics, the first steam generator 5 is turned on first, and the first steam generator 5 generates water that drips downwards, and the second steam generator 6 heats the dripping water to generate steam.

[0256] During the rotation of the fabric processing drum 4, the fabric is affected by the lifting ribs 41 and moves to the first position 2 in the figure, and then the fabric leaves the wall of the fabric processing drum 4 and moves to the second position 3 in the figure to achieve the throwing of the fabric.

[0257] Through the above content, the heating pipe used by the fabric processing equipment to heat the washing water is used as the second steam generator 6 to generate steam during care without the need for additional hardware, which is beneficial to saving the internal space and cost of the fabric processing equipment.

[0258] For ease of understanding, Figure 6As shown, from the start, select the fabric care program you need to use, put in the fabric, and start the machine. At this time, the heating tube in the steam generator will start to run, heating the water in the steam box to generate steam. When the steam box starts to generate steam, the heating tube in the steam generator will stop running. After that, the stage of heating the bottom heating tube to generate steam will begin. It is worth noting that in the previous step of the process, a part of water has entered the bottom of the cylinder. The amount of water is not lower than the liquid level of the bottom heating tube, nor higher than the height between the inner and outer cylinders. At this time, the bottom heating tube heats the water at the bottom of the cylinder to generate steam. When the bottom of the cylinder starts to generate steam, the bottom heating tube stops running, and then the heating tube in the steam generator above the cylinder is turned on, and steam is generated again in the steam box. At this time, the two heating tubes will be turned on alternately to generate steam to humidify the fabric in the cylinder. At the same time, the fabric treatment cylinder 4 will adapt the appropriate rotation speed according to the moisture content of the fabric, so that the fabric load is always in a relatively good throwing state. After that, it will determine whether the fabric has reached the required moisture content. If not, the previous process will be repeated to continue humidification. If it has reached it, the steam ironing stage will end and the drying stage will begin. After that, the entire care process will end and the machine will be turned off.

[0259] Among them, as shown in the following table,

[0260]

[0261] Due to the inherent properties of fabrics, different fabrics require different moisture contents to meet the required care requirements. Fabrics absorb moisture during care by absorbing steam from a steam generator to reach the required moisture content. However, some fabrics, such as synthetic fibers and wool, are hydrophobic and less receptive to steam absorption. This makes it difficult to achieve a sufficient moisture content within a limited timeframe. Therefore, bottom-heating is used to assist in steam generation to increase the amount of steam absorbed by the fabric. The power of the heating element is typically high, so to prevent excessive power consumption when both elements are activated simultaneously, they are operated in an alternating pattern. The alternating activation time varies depending on the fabric's moisture absorption capacity and difficulty absorbing moisture. The greater the steam requirement and the more difficult it is to absorb steam, the greater the activation time of the bottom-heating element, and vice versa. This is because the amount of steam generated by bottom-heating is very high, effectively assisting in humidifying the fabric. When the two heating tubes are turned on alternately, the operation duration of the heating tube in the steam generator is t1, and the operation time of the heating tube at the bottom of the drum is t2. t1 and t2 cannot last too long each time. If t1 is too long, it will easily cause the water temperature at the bottom of the drum to drop too much, and it will take a long time to reheat and generate steam. If t2 is too long, it will easily cause the moisture content of the fabric to be uncontrollable, and the fabric will easily get wet, resulting in a fabric with too high moisture content and difficult to dry in a short time. It will also easily cause the water in the steam box to drop too much, and it will take a lot of time to reheat and generate steam. Therefore, t1 and t2 should be balanced so that steam is always flowing into the drum during the entire process. From the figure we can find that different fabric materials correspond to different drum bottom heating time ratios. Wool and chemical fiber materials are least likely to absorb steam, so the drum bottom heating time ratio is the largest. Next are fabrics that are relatively easy to absorb steam and have a large steam demand, namely cotton, linen, silk, and shirts. The drum bottom heating time ratios of these three programs are in the middle. Finally, suits and mink fur are these two fabric materials. They do not require much steam and are relatively easy to absorb steam, so the drum bottom heating time ratio is the lowest. Finally, the order of all drum bottom heating time ratios is N2>N3>N4>N1>N5>N7>N6.
