[0031] The operating parameters of the sterilization program are adjusted according to the amount of clothing.

[0032] In an optional technical solution of the control method of the above-mentioned clothing care machine, the clothing care machine includes an ozone generating module and a blower, and the blower is used to blow the generated ozone into the care cavity;

[0033] The step of “adjusting the operating parameters of the sterilization program according to the amount of clothing” includes:

[0035] The speed of the fan when the ozone generating module is turned on is a first preset speed, and the speed of the fan when the ozone generating module is turned off is a second preset speed;

[0036] The first preset speed is less than the second preset speed. As the amount of clothes increases, the first preset speed gradually increases, and the second preset speed gradually decreases.

[0037] The present invention also provides a clothing care machine, which includes a controller and a memory, wherein the memory is suitable for storing multiple program codes, and the program codes are suitable for being loaded and run by the controller to execute the control method of the clothing care machine described in any of the above technical solutions.

[0038] Those skilled in the art will appreciate that the control method of the clothing care machine of the present invention includes: controlling the clothing care machine to operate the steam function; obtaining the weight increase of the clothes inside the care cavity when the steam function is operated for a time period of T; obtaining the temperature change value in the care cavity when the steam function is operated for a time period of T; and determining the amount of clothes in the care cavity based on the weight increase value and the temperature change value, wherein the amount of clothes = n pieces of standard clothes, and n is a constant.

[0039] When the above technical solution is adopted, the present invention inputs steam into the clothing care cavity, the air temperature in the care cavity increases, and after the steam contacts the clothing, the clothing absorbs the steam moisture and becomes wet, and the weight of the clothing increases.

[0040] If the material of the clothing remains unchanged, a large increase in the weight of the clothing indicates a high water absorption rate, a large clothing area, and a correspondingly larger clothing volume. When the clothing volume is large, the clothing absorbs more steam at a faster rate, resulting in less steam liquefaction, less heat release, and a slower temperature rise in the care cavity. Therefore, the greater the clothing volume, the smaller the temperature change in the care cavity, and vice versa. However, it should be noted that the clothing volume in the present invention is not necessarily the same as the actual number of clothing items in the care cavity. Instead, a piece of clothing of a set material and area is used as a standard piece of clothing. The clothing volume = n pieces of standard clothing. The clothing volume is standardized using the standard piece of clothing, and the actual total amount of clothing items in the care cavity is converted into the number of standard pieces of clothing.

[0041] Based on the above principle, by pre-storing the mapping relationship between the increase in clothing weight and the temperature change value of the care cavity and the amount of clothing in the database, the amount of clothing is automatically obtained according to the measured increase in clothing weight and the temperature change value of the care cavity. The comprehensive determination of the amount of clothing by the increase in clothing weight and the temperature change value of the care cavity can not only improve the accuracy of the clothing amount judgment, but also adjust the subsequent care parameters according to the standardized clothing amount, which can improve the care effect on the clothing.

[0049] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the present application is described in conjunction with a clothing care machine, this is not restrictive, and the control method of the present invention can also be applied to other clothing processing equipment, such as a dryer, a washer-dryer, etc., and can also be applied to other equipment besides clothing processing equipment.

[0050] It should be noted that, in the description of the present invention, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0051] Specifically, refer to Figure 4 The clothing care machine of the present invention includes a cabinet 1 and a steam generating device 2. A care cavity 11 is provided in the cabinet 1, and a steam outlet 12 is provided on the wall of the care cavity. The steam generating device 2 is provided in the cabinet 1 and steam is supplied to the care cavity 11 through the steam outlet 12 to perform steam care on the clothes. The clothing care machine also includes a hanging rack 3, which is provided on the top of the care cavity 11, and the clothes are hung on the hanging rack 3.

[0052] Furthermore, the clothing care machine also includes a drying module and a sterilization module. The drying module includes a heater and a drying fan. After the heater heats the air, the drying fan blows the heated air into the care cavity 11 for drying the clothes. The sterilization module includes an ozone generating module and a fan. The ozone generated by the ozone generating module is blown into the care cavity 11 under the action of the fan, thereby sterilizing and deodorizing the clothes. It should be noted that in addition to being an ozone sterilization module, the sterilization module can also be a photoplasma module, etc. Those skilled in the art can set the specific sterilization method and structure of the sterilization module according to their needs.

[0053] Those skilled in the art will understand that the present invention does not impose any restrictions on the specific structure of the clothing care machine. Technicians can set the specific structure of the clothing care machine according to actual usage requirements. Such changes in specific application objects do not deviate from the basic principles of the present invention and fall within the scope of protection of the present invention.

[0054] Furthermore, the clothing care machine also includes a temperature sensor, a weight sensor 4 and a controller. The temperature sensor is used to detect the temperature value in the care cavity 11, and there is no setting for the setting position of the temperature sensor. The weight sensor 4 is set on the hanger 3 to detect the weight of the hanging clothes, but there is no restriction on the setting position of the weight sensor 4. Those skilled in the art can set it by themselves as needed, as long as they can detect the weight of the clothes. The controller can obtain the temperature value and the weight of the clothes in the care cavity 11, and the controller can also control the operation of the steam generator 2, the operation of the ozone generation module, and the operation of the drying module, etc. It can be understood by those skilled in the art that the present invention does not impose any restrictions on the specific structure and model of the controller, and the technicians can set the structure and model of the controller according to actual use requirements.

[0055] like Figure 1 As shown, in order to solve the problem that the user forgets or incorrectly sets the total amount of clothes, resulting in poor clothing care effects, the control method of the clothing care machine of the present invention includes:

[0056] Step S10: Control the clothing care machine to run the steam function.

[0057] By turning on the steam generating device 2 to input steam into the clothing care cavity 11 , after the steam contacts the clothing, the clothing absorbs moisture from the steam and becomes wet, and the heat carried by the steam increases the air temperature in the care cavity 11 .

[0058] Step S20: Obtaining the weight increase ΔM of the underwear when the steam function is running for T time;

[0059] Step S30: Obtain the temperature change value ΔT in the care cavity during the operation of the steam function for T time.

[0060] After the clothes are soaked, their weight will increase accordingly, and the temperature in the care cavity 11 will also increase accordingly. By obtaining the weight M1 of the clothes before T time, and then obtaining the weight M2 of the clothes after T time, M2-M1 is used to obtain the weight increase value △M of the clothes. Similarly, by obtaining the air temperature T1 in the care cavity 11 before T time, and then obtaining the air temperature T2 in the care cavity 11 after T time, T2-T1 is used to obtain the temperature change value △T in the care cavity 11.

[0061] Step S40: Determine the amount of clothing in the nursing cavity according to the weight increase value ΔM and the temperature change value ΔT.

[0062] When the material of the clothing remains unchanged, the larger ΔM is, the more water it absorbs, indicating a larger clothing area and a correspondingly larger amount of clothing. When the amount of clothing is large, the clothing absorbs more steam and faster, resulting in less steam liquefaction, less heat release, and a slower temperature rise in the care cavity 11. Therefore, the more clothing there is, the smaller ΔT is, and vice versa. However, it should be noted that the amount of clothing in the present invention is not necessarily the same as the actual number of clothing in the care cavity 11. Instead, a piece of clothing with a set material and area is used as a standard piece of clothing. The clothing amount = n pieces of standard clothing. The clothing amount is standardized by the standard clothing, and then the actual total amount of clothing in the care cavity 11 is converted into the number of standard pieces of clothing. For example, when ΔM is 50g and ΔT is 2°C, the amount of clothing in the care cavity 11 is 2 pieces of standard clothing.

[0063] Based on this principle, the mapping relationship between the clothing weight increase △M and the temperature change value △T in the care cavity 11 and the clothing quantity is stored in the database of the clothing care machine. The clothing quantity is automatically obtained through the measured △M and △T. The clothing quantity is comprehensively determined by the clothing weight increase and the temperature change value in the care cavity 11, which can improve the accuracy of clothing quantity determination. By adjusting subsequent care parameters through standardized clothing quantity, the care effect on clothing can be improved.

[0064] The mapping relationship between the clothing weight increase ΔM, the temperature change ΔT, and the clothing quantity can be obtained based on experimental data or empirical formulas. Persons skilled in the art may customize the acquisition method as needed, and all such methods fall within the scope of the present invention. For example, if ΔM is 150g and ΔT is 5°C within 2 minutes, the corresponding clothing quantity can be determined based on these two values ​​as 3 standard pieces of clothing.

[0065] Of course, in addition to specific values, the clothing weight increase value ΔM, the temperature change value ΔT in the care cavity, and the amount of clothing can also be numerical ranges. Those skilled in the art can set them according to their needs, and they all fall within the scope of protection of the present invention.

[0066] Those skilled in the art can set the T time as needed, which can be 1 minute, 2 minutes, 5 minutes, etc. The present invention does not impose any limitation on the T time, and all of them fall within the protection scope of the present invention.

[0067] like Figure 2 As shown, in a possible implementation manner, the specific steps of the control method of the clothing care machine are as follows:

[0068] Step S51: controlling the clothing care machine to operate the steam function;

[0069] Step S52: Obtaining the weight increase ΔM of the underwear when the steam function is running for T time;

[0070] Step S53: obtaining a temperature change value ΔT in the care cavity during the operation of the steam function for a time period of T;

[0071] Step S54: obtaining the material of the clothing in the care cavity;

[0072] Step S55: determining the amount of clothing in the care cavity according to the measured clothing material, ΔM and ΔT; wherein the clothing material, weight increase value ΔM, temperature change value ΔT and clothing amount are in a mapping relationship.

[0073] When the material of the clothing is different, due to its different water absorption, the corresponding weight increase value and temperature change value will also change. For example, the clothing material is cotton, which has better water absorption than silk, so ΔM will increase and ΔT will decrease. Therefore, the database stores a plurality of mapping relationships between the weight increase value ΔM, the temperature change value ΔT and the amount of clothing corresponding to the clothing material. After the material of the clothing in the care cavity 11 is detected, the amount of clothing is determined according to the mapping relationship corresponding to the clothing material. The standard clothing under this mapping relationship is the same as the material of the clothing in the care cavity 11. The clothing material can be measured by an image sensor, or it can be input or set by the user, etc., and those skilled in the art can set it according to their needs.

[0074] However, it should be noted that the clothing in the nursing cavity 11 can be made of the same material as or different from the standard clothing in the mapping relationship. When the clothing in the nursing cavity 11 is made of a different material from the standard clothing in the mapping relationship, the conversion can be performed based on the water absorption characteristics of the two materials. A high water absorption rate indicates good water absorption, and a low water absorption rate indicates poor water absorption. For example, the water absorption ratio a of the standard clothing and the clothing in the nursing cavity 11 is calculated, and the measured △M and △T are multiplied by a for correction. The corrected values ​​are then substituted into the mapping relationship to obtain the amount of clothing under the standard clothing. For example, if the water absorption rate of the clothing in the nursing cavity 11 is twice that of the standard clothing in the mapping relationship, then a=0.5, and the measured △M and △T are multiplied by 0.5, and then substituted into the mapping relationship to obtain the amount of clothing under the standard clothing. Those skilled in the art can set it as needed, and it falls within the scope of protection of the present invention.

[0075] like Figure 3 As shown, step S55 further includes:

[0076] Step S551: determining whether the material of the clothing in the nursing cavity is the same as the material of the standard clothing;

[0077] If the judgment result of step S551 is not the same, step S552 is executed;

[0078] Step S552: Calculating the water absorption ratio a of the standard clothing material and the clothing material in the care cavity;

[0079] Step S553: ​​Correcting the measured ΔM and ΔT; wherein the corrected weight increase value = ΔM*a, and the corrected temperature change value = ΔT*a;

[0080] Step S554: determining the amount of clothing in the nursing cavity according to the corrected weight increase value and the corrected temperature change value;

[0081] If the result of step S551 is the same, then step S555 is executed;

[0082] Step S555: directly determining the amount of clothing in the care cavity based on the measured ΔM and ΔT.

[0083] Continue to refer to Figure 2 After step S55, the control method further includes:

[0084] Step S56: Adjust the operating parameters of the steam care program according to the amount of clothes.

[0085] The steam care program is to control the operation of the steam generating device 2 to send steam into the care cavity 11 to perform steam care on the clothes, thereby achieving the effect of removing wrinkles on the clothes.

[0086] Step S56 further includes:

[0087] Steps: Adjust the running time and steam output of the steam care according to the amount of clothes.

[0088] When the load is heavy, steam doesn't easily fully contact the clothes. Therefore, increasing the duration of the steam treatment or the steam output can enhance the steam output, allowing the steam to fully contact the clothes and improving the treatment effect. When the load is light, shortening the steam treatment duration or reducing the steam output can save energy. The steam output can refer to the total steam output flow rate or the steam output flow rate per unit time. Those skilled in the art can adjust the steam output according to their needs, as long as it improves the intensity of the steam treatment and falls within the scope of the present invention.

[0089] The step of “adjusting the running time and steam output of steam care according to the amount of clothes” further includes:

[0090] Step: when the amount of clothes is the first amount of standard clothes, the running time of the steam care is the fourth preset time, and the steam output of the steam care is the first preset steam amount;

[0091] Step: when the amount of clothes is the second amount of standard clothes, the running time of the steam care is the fifth preset time, and the steam output of the steam care is the second preset steam amount;

[0092] Among them, the first quantity is less than the second quantity, the fourth preset time is less than the fifth preset time, and the first preset steam volume is less than the second preset steam volume.

[0093] It should also be noted that the steam function in step S10 can also be part of a steam care program. After determining the amount of clothing, the parameters of the subsequent steam care program can be adjusted according to the amount of clothing. Those skilled in the art can set these parameters as needed, and all such parameters fall within the scope of protection of the present invention. In addition to the operating time and steam output, the operating parameters of the steam care program can also be other parameters. Those skilled in the art can set these parameters as needed, and all such parameters fall within the scope of protection of the present invention.

[0094] Continue to refer to Figure 2 After step S55, the control method further includes:

[0095] Step S57: Adjust the operating parameters of the drying program according to the amount of clothes.

[0096] The drying program is to control the operation of the heater and the drying fan, so as to send dry hot air into the care cavity 11 to dry the wet clothes.

[0097] Step S57 further includes:

[0098] Steps: Adjust the drying time and temperature according to the amount of clothes.

[0099] When there are a lot of clothes, heat is not easy to dissipate. Therefore, the drying effect can be improved by increasing the drying time or drying temperature. When there are fewer clothes, energy can be saved by shortening the drying time or lowering the drying temperature.

[0100] The step of “adjusting drying time and drying temperature according to the amount of clothes” further includes:

[0101] Step: when the amount of clothes is the first quantity of standard clothes, the drying time is the sixth preset time, and the drying temperature is the first preset temperature;

[0102] Step: when the amount of clothes is the second amount of standard clothes, the drying time is the seventh preset time, and the drying temperature is the second preset temperature;

[0103] The first quantity is less than the second quantity, the sixth preset time is less than the seventh preset time, and the first preset temperature is less than the second preset temperature.

[0104] The operating parameters of the drying program may be other parameters in addition to the drying time and the drying temperature, and those skilled in the art may set them as needed, and all of them fall within the scope of protection of the present invention.

[0105] Continue to refer to Figure 2 After step S55, the control method further includes:

[0106] Step S58: adjusting the running parameters of the sterilization program according to the clothing amount.

[0107] The sterilization program is specifically a sterilization and deodorization process on the clothes by turning on the sterilization module. After determining the clothing amount, the running parameters of the sterilization program are adjusted according to the clothing amount, for example, the running time or sterilization intensity of the sterilization module, and the like.

[0108] Taking the ozone module sterilization as an example, in order to improve the ozone sterilization and deodorization effect and ensure that the ozone concentration in the care cavity 11 is maintained within a reasonable range to avoid adverse reactions after the user opens the door, step S58 further includes:

[0109] Step: controlling the ozone generation module to be turned on intermittently, and the opening time of the ozone generation module gradually shortens during the intermittent opening;

[0110] Step: the rotating speed of the fan when the ozone generation module is turned on is a first preset rotating speed, and the rotating speed of the fan when the ozone generation module is turned off is a second preset rotating speed;

[0111] Among them, with the increase of the clothing amount, the first preset rotating speed gradually decreases and the second preset rotating speed gradually increases, and the first preset rotating speed is less than the second preset rotating speed.

[0112] When sterilizing and deodorizing the clothes in the care cavity 11, the ozone generation module is intermittently turned on, and the opening time of the ozone generation module gradually shortens during the intermittent opening. Since the ozone entering the care cavity 11 in the early stage has not been completely decomposed, the opening time of the ozone module is gradually reduced in the later stage, so that the ozone concentration can always be maintained below the national standard. When the ozone generation module is turned on, the fan rotates at a low speed, and the low-speed airflow blows the ozone to the clothes, so that the ozone can fully contact the clothes and ensure the sterilization and deodorization effect. When the ozone generation module is turned off, the fan rotates at a high speed, so that the ozone rapidly diffuses under the action of the airflow, thereby reducing the ozone concentration in the unit space. Even if the user suddenly opens the door during the clothes care process, he or she will not feel dizzy and nauseated due to inhaling high-concentration ozone. When the clothing amount is large, the first preset rotating speed is reduced and the second preset rotating speed is increased, so that the fan rotating speed when the ozone module is turned on is reduced, thereby further improving the contact between the ozone and the clothes, and the fan rotating speed after the ozone module is turned off is increased, thereby improving the diffusion effect of the ozone in the clothes gap and reducing the ozone concentration. When the clothing amount is reduced, the diffusion effect of the ozone is good, so the first preset rotating speed is increased and the second preset rotating speed is reduced, thereby ensuring the sterilization effect of the clothes and ensuring that the ozone concentration in the care cavity 11 is within the national standard range, preventing the user from having adverse reactions after opening the door.

[0113] To sum up, the present invention determines the amount of clothing based on the increase in clothing weight and the temperature change in the care cavity 11 after the steam comes into contact with the clothing for a period of time, and improves the accuracy of clothing amount determination by standardizing the clothing amount, and then adjusts the care parameters according to the clothing amount to improve the subsequent care effect. In addition, the present invention also intermittently turns on the ozone generating module when running the sterilization program and cooperates with the fan speed control to keep the ozone concentration in the care cavity 11 within a reasonable range at all times, thereby preventing the user from inhaling excessive ozone after opening the door and causing adverse reactions.
