Description

Technical Field

[0001] This invention relates to the field of steam irons, and more particularly to a method, system, and apparatus for preventing steam irons from leaking. Background Technology

[0002] A steam iron is an electrical appliance that uses steam to iron clothes, making them smoother and more even, while also disinfecting and sterilizing them.

[0003] In existing technology, water is typically heated to its boiling point by a heating device to generate steam, and the steam is then piped into the iron. At the same time, the liquid water condensed from the steam in the iron is piped back into the heating device to be reheated and generate steam.

[0004] When using an iron, the soleplate should face the clothes. If the clothes are not placed horizontally, the angle of the iron needs to be adjusted. This can easily cause liquid water inside the iron to flow back into the pipes, resulting in liquid water leakage and causing the clothes to become damp. Summary of the Invention

[0005] To improve the ease of use of steam irons and reduce leaks, this invention provides a method, system, and device for preventing leaks in steam irons.

[0006] In a first aspect, the present invention provides a method for preventing water leakage in a steam iron, employing the following technical solution:

[0007] A method for preventing water leakage in a steam iron includes:

[0008] Capture images of the steam iron's placement;

[0009] Identify the orientation of the iron from the placement image;

[0010] When the iron is oriented into the preset inverted range, a water collection length is generated in response to the iron's orientation;

[0011] A water collection command is generated in response to the water collection length.

[0012] Send a water collection command to the preset water collection device to drive the water collection device to unfold.

[0013] By adopting the above technical solution, the orientation of the iron can be monitored in real time from the image. When the iron is tilted, the length of the water collection device that can receive any leaked liquid can be selected. Then, the water collection device is expanded at the bottom of the iron to reduce the leakage of liquid onto the clothes, thereby improving the convenience of using the steam iron.

[0014] Optional, also includes:

[0015] When the iron falls into the preset inverted zone, the weight information of the liquid in the water collection device is collected.

[0016] Generates a weight fluctuation curve in response to weight information;

[0017] The fall height is generated in response to the undulating curve.

[0018] The system retrieves an iron model based on the fall height and identifies the leaking area from the iron model in which the iron is facing.

[0019] Responding to the location / range to generate a leak alarm command;

[0020] Send a leak alarm command to the preset alarm device to issue a partial leak alarm.

[0021] By adopting the above technical solution, the weight of the liquid received in the water collection device can be monitored in real time. The weight can be used to determine whether there is a leak. If a leak is found, the location of the leak can be estimated from the weight change, so as to notify the user in time to deal with the leak and reduce the occurrence of iron leaks.

[0022] Optionally, the method for generating the fall height includes:

[0023] Identify the points of weight change from the fluctuation curve;

[0024] Based on the points of change, the peak weight and the liquid weight after weight stabilization are identified from the fluctuation curve;

[0025] Calculate the difference between the peak weight and the liquid weight, and define it as the fluctuation range;

[0026] Identify the stable weight before the weight change from the fluctuation curve based on the point of change;

[0027] Calculate the difference between the liquid weight and the steady-state weight, and define it as the droplet weight;

[0028] The falling velocity is generated in response to the amplitude of the fluctuation and the weight of the water droplet;

[0029] The fall height is generated in response to the fall speed.

[0030] By adopting the above technical solution, the speed at which the water droplet falls into the water collection device can be estimated from the weight change detected after the water droplet falls into the water collection device, thereby estimating the height of the water droplet's falling position from the water collection device, and thus improving the accuracy of the prediction of the leakage location.

[0031] Optionally, the method for identifying the region includes:

[0032] Extract the fall position at the fall height based on the iron model with the iron's orientation;

[0033] The contact angle is extracted from the iron model based on the fall location;

[0034] When the contact angle falls within the preset dripping range, the falling position is defined as the dripping position;

[0035] The delivery position is retrieved in response to the dripping position, and the part angle between the dripping position and the delivery position is extracted from the iron model in which the iron is facing.

[0036] When the angle of the part does not fall within the preset dripping range, a part range is generated in response to the delivery position.

[0037] By adopting the above technical solution, when there is a leak, the position of the iron at the current upward distance from the water collection device is read as the drop height, and the position that is located at the edge where water can drip is screened out. At the same time, it is checked whether there is an edge where water can drip between the location of the pipe and the position where water can drip, thereby further screening out the possible locations where water droplets may drip, thus improving the accuracy of the leak location prediction.

[0038] Optionally, a leak repair method may also be included, the leak repair method comprising:

[0039] When the iron falls into the preset inverted range, the dripping frequency is read based on the point of change;

[0040] The degree of leakage is determined by the frequency of dripping and the weight of the water droplets;

[0041] When the leakage level exceeds the preset damage threshold, it is determined whether the area is located at the input position, where the delivery position includes the input position and the output position.

[0042] When the part range is at the input position, a reverse instruction is generated;

[0043] Send a reverse command to the preset conveying device to input steam to the output position, and update the input and output positions.

[0044] By adopting the above technical solution, when the leak is located in the steam input pipe, the steam in the pipe can easily escape from the leak, resulting in the user being scalded by high-temperature steam. In this case, the steam input pipe is replaced, so that the leak occurs in the liquid water output pipe, thereby improving the safety of using the steam iron.

[0045] Optionally, the leakage repair method further includes:

[0046] When the part interval is not located at the input position, read the surface angle from the output position to the edge of the bottom surface of the iron from the iron model in which the iron is facing;

[0047] The falling path of water droplets in an iron model with different orientations is simulated based on the order of surface angles from largest to smallest.

[0048] Generate the falling direction in response to the falling path;

[0049] A blowing command is generated in response to the direction of descent;

[0050] Send a blowing command to a preset blowing device to disperse water droplets through airflow.

[0051] By adopting the above technical solution, when the water leakage is serious, water droplets are likely to leak out when ironing clothes with a steam iron, causing the clothes to become damp. In this case, the path of the water droplets after leaking from the leaking point and flowing down the iron can be estimated from the shape of the iron. Then, the blower is used to blow air onto the surface of the iron to deflect the water droplets on the iron surface, thereby lengthening the path of the water droplets from the leaking point to the clothes, thus reducing the amount of water droplets falling into the clothes.

[0052] Optionally, the leakage repair method includes:

[0053] When the part is not located at the input position, the dissipation distance is generated in response to the weight of the water droplet;

[0054] Generate the fall distance in response to the fall path;

[0055] When the falling distance is lower than the dissipation distance, an offset angle is generated in response to the dissipation distance and the falling distance;

[0056] The blowing force is generated in response to the offset angle;

[0057] A blowing command is generated in response to the direction of descent and the force of the blowing.

[0058] By adopting the above technical solution, when the leakage is serious, a longer path is required for the leaked liquid to be consumed. When the path length of the water droplet flowing on the surface of the iron after leaking from the leak location is insufficient, the blowing force is increased by the blower, thereby increasing the deviation of the water droplet on the iron surface and reducing the amount of water droplet falling into the clothes.

[0059] Optionally, a filtering method may also be included, the filtering method comprising:

[0060] A collection threshold is generated in response to the water collection length;

[0061] When the weight information exceeds the collection threshold, a standby command is generated;

[0062] Send a standby command to the filter device preset in the water collection device to drive the filter device to move to the preset standby position and generate an extraction command;

[0063] Send an extraction command to a preset water collection device to extract the liquid in the water collection device into a preset container, and generate a filtration speed in response to the weight information.

[0064] Filtering instructions are generated in response to the filtering speed.

[0065] Send a filtration command to the filter device pre-installed in the water collection device to drive the filter device to move within the pre-installed container to filter impurities in the liquid.

[0066] By adopting the above technical solution, when the liquid flows on the surface of the iron, it is easy to generate many impurities in the liquid, which makes the liquid in the water collection device relatively turbid. The liquid in the water collection device is filtered by the filtration device to reduce the impurities in the liquid, thereby facilitating the secondary use of the liquid.

[0067] Secondly, this application provides a leak-proof system for a steam iron, employing the following technical solution:

[0068] A leak-proof system for a steam iron includes:

[0069] The acquisition module is used to acquire placement images and weight information;

[0070] A memory for storing any of the above-mentioned methods for preventing water leakage from a steam iron;

[0071] The processor is the unit of memory that allows programs to be loaded and executed by the processor.

[0072] Thirdly, this application provides a leak-proof device for a steam iron, which adopts the following technical solution:

[0073] A leak-proof device for a steam iron includes a memory and a processor, wherein the memory stores a leak-proof method for any of the steam irons described above that can be loaded and executed by the processor.

[0074] By adopting the above technical solution, the orientation of the iron can be monitored in real time from the image. When the iron is tilted, the length of the water collection device that can receive any leaked liquid can be selected. Then, the water collection device is expanded at the bottom of the iron to reduce the leakage of liquid onto the clothes, thereby improving the convenience of using the steam iron.

[0075] In summary, this application includes at least one of the following beneficial technical effects:

[0076] By monitoring the iron's orientation in real time from the image, the length of the water collection device that can receive any leaking liquid when the iron is tilted is selected. The water collection device is then expanded at the bottom of the iron to reduce the amount of leaking liquid falling onto the clothes, thus improving the ease of use of the steam iron.

[0077] The system monitors the weight of the liquid collected in the water collection device in real time, thereby determining whether there is a leak based on the weight. If a leak is found, the location of the leak can be estimated from the changes in weight, so as to notify the user in time to deal with the leak and reduce the occurrence of iron leaks.

[0078] By analyzing the weight change of water droplets after they fall into the water collection device, the velocity of the droplets as they fall into the device can be estimated, thereby predicting the height of the droplets from the collection device and improving the accuracy of leak location prediction.

[0087] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0088] Reference Figure 1 A method for preventing water leakage in a steam iron, comprising:

[0089] Step 100: Capture an image of the steam iron's placement.

[0090] The placement image refers to the image taken within the processing station, which is the area used to place clothes to be ironed. The placement image can be obtained through a camera fixed within the processing station. The method of obtaining the placement image is selected by the staff according to the actual situation, and will not be elaborated here.

[0091] Step 101: Identify the orientation of the iron from the placement image.

[0092] The orientation of an iron refers to the angle at which the iron is placed. Generally, the orientation of the tip of the iron soleplate is used as the iron's orientation. The orientation of an iron can be identified using image recognition technology. The method for identifying the orientation of an iron is common knowledge to those in the field and will not be elaborated here.

[0093] Step 102: When the iron is oriented into the preset inverted zone, a water collection length is generated in response to the iron's orientation.

[0094] The inverted zone refers to the zone in which the liquid inside the iron is likely to backflow into the pipes. The inverted zone is selected by the staff based on the actual situation, and will not be elaborated here. When the iron is oriented into the inverted zone, it means that the liquid inside the iron is likely to backflow and cause leakage.

[0095] A water collection device is a device located on the side of the iron handle away from the soleplate tip, designed to collect leaked liquid. The pipes for transporting steam and liquid are generally located on the side of the iron away from the soleplate tip. This means that the direction of liquid backflow from the iron is away from the soleplate tip, and therefore, when leakage occurs, the liquid also leaks away from the soleplate tip. The water collection device extends to form a groove at the bottom of the pipe to collect the liquid. An internal pump then draws the liquid from the groove into a pre-set container for storage, reducing the chance of leakage onto clothing. The container is the device within the water collection device used to store the liquid. The selection of the water collection device is made by the operator based on the actual situation and will not be elaborated upon here.

[0096] The water collection length refers to the length of the water collection device that it extends to receive liquid. The water collection length can be obtained from the length relationship table, which is a data table that records different iron orientations and their corresponding water collection lengths.

[0097] Step 103: Generate a water collection command in response to the water collection length.

[0098] The water collection command is a signal used to control the water collection device to shrink according to the water collection length. The method of generating the water collection command is common knowledge to those in the field and will not be described in detail here.

[0099] Step 104: Send a water collection command to the preset water collection device to drive the water collection device to unfold.

[0100] By monitoring the iron's orientation in real time from the image, the water collection device can be selected to collect any leaking liquid when the iron is tilted. The water collection device then expands at the bottom of the iron to reduce the amount of leaking liquid falling onto clothes, thus improving the ease of use of the steam iron.

[0101] Reference Figure 2 A method for preventing water leakage in a steam iron also includes:

[0102] Step 105: When the iron falls into the preset inverted zone, collect the weight information of the liquid in the water collection device.

[0103] Weight information refers to the weight of the liquid received in the groove formed by the extension of the water collection device. This weight information can be obtained by a weight sensor pre-installed in the water collection device. When the iron is inverted, the water collection device unfolds to receive the liquid. At this time, the weight sensor works to detect the overall weight of the liquid. When the iron angle changes again, the water pump inside the water collection device draws the liquid into the internal container. The method of collecting weight information is selected by the staff according to the actual situation, and will not be elaborated here.

[0104] Step 106: Generate a weight fluctuation curve in response to weight information.

[0105] A fluctuation curve is a curve showing the change in the weight of a liquid over time, formed by combining weight and time information. The time information refers to the moment when the weight information is acquired, which can be obtained through a timer. The method for generating the fluctuation curve is common knowledge to those skilled in the art and will not be elaborated here.

[0106] Step 107: Generate the fall height in response to the oscillation curve.

[0107] The drop height refers to the height of the liquid drop position from the water collection device. The higher the liquid drops, the greater the impact force on the water collection device when the liquid drops to the water collection device. The impact force caused by the liquid in the fluctuation curve is read to estimate the drop height of the liquid.

[0108] Step 108: Retrieve the iron model in response to the fall height, and identify the area of ​​leakage from the iron model in which the iron is facing.

[0109] An iron model refers to the three-dimensional parameters of an iron. The iron model can be pre-input by staff or obtained in real time by scanning from the placement image. The method of retrieving the iron model is selected by the staff according to the actual situation, and will not be elaborated here.

[0110] The delivery position refers to the location on the iron's surface where the pipes are connected. The delivery position includes the input position and the output position. The input position is the connection point on the iron's surface where the pipes that deliver steam to the inside of the iron are connected. The output position is the connection point on the iron's surface where the pipes that output liquid from the inside of the iron are connected. When the iron leaks water, it means that the pipes are leaking, meaning that the source of the leak is either the input or output position.

[0111] The location range refers to the area where water leakage occurs. The location that is at the drop height and can drip can be found in the iron model. The location where dripping occurs can be traced back to the conveying location, and the location range can be generated from the conveying location.

[0112] Step 109: Generate a leak alarm command in response to the location area.

[0113] An alarm device is a device used to alert users to the presence of a water leak. The alarm device is selected by the staff based on the actual situation and will not be elaborated upon here. A leak alarm command is a message used to control the alarm device to issue a partial leak alarm. A partial leak alarm notifies the user that a leak exists in a specific area. The production method of the leak alarm command is common knowledge to those skilled in the art and will not be elaborated upon here.

[0114] Step 110: Send a water leakage alarm command to the preset alarm device to issue a partial water leakage alarm.

[0115] The system monitors the weight of the liquid collected in the water collection device in real time, thereby determining whether there is a leak. If a leak is found, the system can estimate the location of the leak based on changes in weight, and promptly notify the user to address the leak and reduce the occurrence of leaks in the iron.

[0116] Reference Figure 3 The methods for generating the fall height include:

[0117] Step 200: Identify the points of weight change from the fluctuation curve.

[0118] The change point refers to the starting moment when the data in the fluctuation curve changes. When liquid falls into the water collection device, the weight detected by the weight sensor first increases, then decreases and stabilizes. The change point is the time point in the fluctuation curve when the weight increases. The method for identifying the change point is common knowledge to those in the field and will not be elaborated here.

[0119] Step 201: Identify the peak weight and the liquid weight after weight stabilization from the fluctuation curve based on the points of change.

[0120] The peak weight refers to the maximum weight change after the point of change in the fluctuation curve. The liquid weight is the weight value that decreases and remains stable after the peak weight. The methods for identifying the peak weight and the liquid weight are common knowledge in the field and will not be elaborated here.

[0121] Step 202: Calculate the difference between the peak weight and the liquid weight, and define it as the fluctuation range.

[0122] Fluctuation amplitude refers to the difference between the peak weight and the liquid weight, and it reflects the impact force of the liquid on the water collection device.

[0123] Step 203: Identify the stable weight before the weight change from the fluctuation curve based on the point of change.

[0124] Stable weight refers to the stable weight value of the fluctuation curve before the point of change. The method for identifying stable weight is common knowledge to those in the field and will not be elaborated here.

[0125] Step 204: Calculate the difference between the liquid weight and the stable weight, and define it as the water droplet weight.

[0126] The weight of a water droplet refers to the weight of the liquid itself when it falls into the water collection device. When the liquid falls into the water collection device, the impact force causes the weight sensor to detect an inflated value. Only after the impact force dissipates and the weight information stabilizes can the reading be the actual weight of the liquid. The weight of the water droplet can be determined by calculating the difference between the liquid weight and the stable weight.

[0127] Step 205: Generate the falling velocity in response to the fluctuation amplitude and the weight of the water droplet.

[0128] The falling velocity refers to the contact speed required for a water droplet of the weight to cause a fluctuation in the amplitude of the impact force on a water collection device. The method for determining the falling velocity is common knowledge to those skilled in the art and will not be elaborated here.

[0129] Step 206: Generate fall height in response to fall speed.

[0130] The fall height is the height that a water droplet needs to fall to generate a falling velocity. The method for determining the fall height is common knowledge to those in the field and will not be elaborated here.

[0131] By analyzing the weight change of water droplets after they fall into the water collection device, the velocity of the droplets as they fall into the device can be estimated, thereby predicting the height of the droplets from the collection device and improving the accuracy of leak location prediction.

[0132] Reference Figure 4 Methods for identifying regions include:

[0133] Step 207: Extract the fall position at the fall height based on the iron model with the iron's orientation.

[0134] The fall position refers to the outline position of the iron surface facing the iron at a height from the water collection device. The method for extracting the fall position is common knowledge to those skilled in the art and will not be described in detail here.

[0135] Step 208: Extract the contact angle from the iron model based on the fall position.

[0136] The contact angle refers to the angle between the tangent of the droplet at the junction of the liquid, gas, and iron phases and the surface of the iron. The larger the contact angle, the easier it is for the liquid to drip off the iron surface. The contact angle can be read from the iron model. The method for extracting the contact angle is common knowledge to those in the field and will not be elaborated here.

[0137] Step 209: When the contact angle falls into the preset dripping range, the falling position is defined as the dripping position.

[0138] The dripping zone refers to the angular range within which liquid is likely to drip from the iron's surface. This zone is selected by the operator based on the actual situation and will not be elaborated upon here. The contact angle falling within the dripping zone indicates the location where droplets are likely to drip from the iron's surface; the dripping location is the set of positions within the dropping zone where droplets are likely to drip from the iron's surface.

[0139] Step 210: Retrieve the delivery position in response to the drip position, and extract the part angle between the drip position and the delivery position from the iron model facing the iron.

[0140] The part angle refers to the contact angle of the iron surface from the input position and the output position to the drip position. First, draw a line segment with the input position and the output position as endpoints and the drip position respectively, and read the position of the two line segments mapped on the iron surface. Then read the contact angle at the position as the part angle. The method of determining the part angle is common knowledge to those in the field and will not be elaborated here.

[0141] Step 211: When the angle of the part does not fall into the preset dripping range, generate a part range in response to the delivery position.

[0142] If the angle of the part does not fall into the dripping zone, it means that there is no place for liquid to drip from between the conveying position and the dripping position. In other words, the liquid leaking from the conveying position can flow smoothly on the iron surface to the dripping position. At this time, the conveying position is judged as a possible leaking position. If the angle of the part falls into the dripping zone, it means that the liquid leaking from the conveying position is difficult to flow on the iron surface to the dripping position. In other words, it is difficult for liquid droplets to drip at this position. At this time, the conveying position is judged as a position where leakage is impossible.

[0143] When a leak is detected, the position of the iron at the current upward direction relative to the water collection device is read as the drop height, and the locations where water can drip from the edge are selected. At the same time, it is checked whether there is an edge between the location of the pipe and the location where water can drip, thereby further filtering out the possible locations where water droplets may drip, thus improving the accuracy of the leak location prediction.

[0144] Reference Figure 5 Leakage repair methods include:

[0145] Step 300: When the iron falls into the preset inverted range, read the drip frequency based on the point of change.

[0146] The dripping frequency refers to the number of points of change within a unit. The dripping frequency can be read from the fluctuation curve. The method of reading the dripping frequency is common knowledge to those in the field and will not be elaborated here.

[0147] Step 301: Calculate the degree of leakage in response to the dripping frequency and the weight of the water droplets.

[0148] Leakage level refers to a numerical value used to indicate the extent of leakage. It is generally expressed as the amount of water leaked per unit time. The leakage level can be determined by calculating the product of the dripping frequency and the weight of the water droplets.

[0149] Step 302: When the leakage level is higher than the preset damage threshold, determine whether the part range is located at the input position, where the delivery position includes the input position and the output position.

[0150] The damage threshold refers to the maximum level of water leakage that will not affect the ironing of clothes. The damage threshold is selected by the staff based on the actual situation and will not be elaborated here. A leakage level higher than the damage threshold indicates a more serious leakage situation. When using the iron to iron clothes, the leaked liquid is likely to drip onto the clothes, causing them to become damp. In this case, it is necessary to determine whether the area is within the input location. The method for determining the area is common knowledge in this field and will not be elaborated here.

[0151] Step 303: When the part range is at the input position, generate a reverse instruction.

[0152] The location range indicates that the leak occurred at the pipeline transporting high-temperature steam. In this case, the high-temperature steam inside the pipeline is likely to rush out and cause people to be scalded by the steam.

[0153] A conveying device is a device used to extract steam into a pipeline and to extract liquid from the pipeline. The conveying device is selected by the staff according to the actual situation, and will not be elaborated here.

[0154] A reversal command is a message used to control the conveying device to reverse so as to draw liquid from the original steam input pipe and input steam into the original liquid input pipe. The method of generating reversal commands is common knowledge to those skilled in the art and will not be described in detail here.

[0155] Step 304: Send a reverse command to the preset conveying device to input steam to the output position, and update the input and output positions.

[0156] When the leak is located in the steam inlet pipe, the steam can easily escape from the leak, potentially causing burns to the user. In this case, replacing the steam inlet pipe will redirect the leak to the water outlet pipe, thus improving the safety of the steam iron.

[0157] Reference Figure 6 Leakage repair methods also include:

[0158] Step 305: When the part interval is not located at the input position, read the surface angle from the output position to the edge of the bottom surface of the iron from the iron model facing the iron.

[0159] The location interval not being located at the input position indicates that the leak occurred at the pipe where the liquid is output. The surface angle refers to the contact angle on the iron surface from the output position to the edge of the bottom of the iron, that is, the contact angle of the iron surface below the height of the output position in the iron model facing the iron. The method of reading the surface angle is common knowledge to those in the art and will not be elaborated here.

[0160] Step 306: Simulate the falling path of the water droplets in the iron model with the desired orientation based on the order of surface angles from largest to smallest.

[0161] The fall path refers to the trajectory that liquid is most likely to follow after leaking from the output location. The method for determining the fall path is common knowledge to those in the field and will not be elaborated here.

[0162] Step 307: Generate the falling direction in response to the falling path.

[0163] A blower is a device fixed within the processing station used to blow air onto the iron. The blower is selected by the operator based on the actual situation and will not be elaborated upon here. The falling direction is the direction in which the blower blows air towards the location along its falling path. It can be determined by first connecting the start and end points of the falling path to form a straight segment, then reading the midpoint of the straight segment, and finally determining the falling direction based on the spatial relationship between the midpoint and the installation position of the blower. The method for determining the falling direction is common knowledge to those skilled in the art and will not be elaborated upon here.

[0164] Step 308: Generate a blowing command in response to the falling direction.

[0165] A blower command is a message used to control the blower to blow air in the direction of fall so that the water droplets leaking from the output position are blown away as they flow on the surface of the iron. The method for generating blower commands is common knowledge to those skilled in the art and will not be described in detail here.

[0166] Step 309: Send a blowing command to the preset blowing device to blow away the water droplets with airflow.

[0167] When the leakage is severe, water droplets can easily leak out when ironing clothes with a steam iron, causing the clothes to become damp. In this case, the shape of the iron can be used to estimate the path of the water droplets after they leak from the leak point and flow down the iron. Then, a blower can be used to blow air onto the surface of the iron to deflect the water droplets, thereby lengthening the path of the water droplets from the leak point to the clothes and reducing the amount of water droplets falling into the clothes.

[0168] Reference Figure 7 Leakage repair methods include:

[0169] Step 310: When the part interval is not located at the input position, generate the dissipation distance in response to the weight of the water droplet.

[0170] Dispersion distance refers to the minimum flow distance required for a water droplet of different weights to dissipate. The dispersion distance can be obtained from the dispersion data table, which records the dispersion distances corresponding to different water droplet weights.

[0171] Step 311: Generate the fall distance in response to the fall path.

[0172] The fall distance refers to the length of the fall path. The method for generating the fall distance is common knowledge to those in the field and will not be elaborated here.

[0173] Step 312: When the falling distance is lower than the dissipation distance, generate an offset angle in response to the dissipation distance and the falling distance.

[0174] A falling distance less than the dissipation distance means that the water droplet has not dissipated by the time it reaches the soleplate of the iron along the falling path. The offset angle is the angle value that the falling path of the water droplet needs to be offset to increase the falling distance to the dissipation distance. The method for determining the offset angle is common knowledge to those in the field and will not be elaborated here.

[0175] Step 313: Generate blowing force in response to offset angle.

[0176] The blowing force refers to the wind force required for a water droplet to be offset by a certain angle. The method for determining the blowing force is common knowledge to those in the field and will not be elaborated here.

[0177] Step 314: Generate a blowing command in response to the falling direction and blowing force.

[0178] The blower command is used to control the blower to blow air in the direction of descent and with the force of the airflow. When the leakage is severe, a longer path is required for the leaked liquid to be consumed. When the path length of the water droplet on the surface of the iron after leaking from the leak point is insufficient, the blower is used to increase the force of the airflow, thereby increasing the deviation of the water droplet on the iron surface and reducing the amount of water droplet falling into the clothes.

[0179] Reference Figure 8 Filtering methods include:

[0180] Step 400: Generate a collection threshold in response to the water collection length.

[0181] The collection threshold refers to the maximum weight of liquid that the water collection device can stably bear within the groove formed by the unfolding of the water collection device. The collection threshold can be obtained from the collection data table, which is a data table that records different water collection lengths and their corresponding collection thresholds.

[0182] Step 401: When the weight information is higher than the collection threshold, a standby command is generated.

[0183] A weight reading exceeding the collection threshold indicates that the liquid collected in the water collection device has reached its maximum capacity. The liquid in the groove needs to be pumped into a pre-set container within the water collection device. The filter device refers to a filter screen installed inside the container and capable of reciprocating within it. The filter device is selected by the operator based on the actual situation and will not be elaborated upon here. The standby command is information that controls the filter screen device to move to the standby position. The standby position is the position inside the container furthest from the water inlet. The water inlet is the opening through which the water collection device injects liquid from the groove into the container. The method for generating the standby command is common knowledge to those skilled in the art and will not be elaborated upon here.

[0184] Step 402: Send a standby command to the filter device preset in the water collection device to drive the filter device to move to the preset standby position and generate an extraction command.

[0185] The extraction command is a message used to control the water pump in the water collection device to extract the liquid in the groove and inject it into the container through the inlet. The method of generating the extraction command is common knowledge to those in the art and will not be described in detail here.

[0186] Step 403: Send an extraction command to the preset water collection device to extract the liquid in the water collection device into the preset container, and generate a filtration speed in response to the weight information.

[0187] A filtration device is a device used to filter liquids in a container. Filtration devices generally use a filter screen that can move inside the container. The filter screen is driven to move inside the container to squeeze the liquid, thereby filtering out impurities in the liquid to the side of the filter screen closer to the inlet, thus maintaining the cleanliness of the liquid on the side of the filter screen away from the inlet.

[0188] Filtration speed is the speed at which the filter moves within the container. The more liquid that needs to be filtered, the more impurities the filter needs to filter per unit distance. In this case, a lower moving speed should be selected to reduce the chance of filter breakage. The filtration speed can be obtained from the filtration data table, which is a data table that records different weight information and their corresponding filtration speeds.

[0189] Step 404: Generate a filtering command in response to the filtering speed.

[0190] A filtration command is a message used to control the filtration device to move from the standby position to the side of the container near the inlet according to the filtration speed. The method of generating filtration commands is common knowledge to those skilled in the art and will not be described in detail here.

[0191] Step 405: Send a filtration command to the filter device preset in the water collection device to drive the filter device to move in the preset container to filter impurities in the liquid.

[0192] When liquid flows across the surface of the iron, it easily accumulates impurities, making the liquid in the collection device cloudy. A filtration system reduces these impurities, facilitating the reuse of the liquid.
