[0051] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0055] Example 1

[0056] This embodiment provides a control method for a clothes drying machine, which can be used for a clothes drying machine with an air drying function to improve the drying effect of clothes.

[0057] like Figure 1 As shown, after the air-drying program is started, the moisture distribution in the drying items is obtained, and the air-drying program is adjusted according to the moisture distribution.

[0058] Understandably, items of varying materials and sizes have varying water absorption capacities, resulting in varying drying speeds under the same drying conditions. Furthermore, the distribution of moisture within the items, influenced by gravity, also varies. This control method links the drying process to the moisture distribution within the items, allowing for flexible adjustment of the airflow direction based on the actual drying conditions. This addresses the issue of uneven drying caused by fixed-angle airflow or back-and-forth airflow within a fixed range.

[0059] Optionally, the airflow provided by the air-drying program can be air at room temperature or heated air, and the temperature of the airflow can be set according to actual needs.

[0060] Example 2

[0061] This embodiment provides a control method for a clothes drying machine, which is further improved on the basis of the first embodiment.

[0062] like Figure 2 As shown, in this control method, after the air-drying program is started, the moisture distribution in the drying objects is obtained; and the air-drying program is adjusted according to the moisture distribution.

[0063] After starting the air-drying process, the infrared detection module captures a thermal image of the item, which displays its temperature distribution. Because areas with high moisture content have lower temperatures and areas with low moisture content have higher temperatures, the surface temperature of the item varies depending on the moisture content. By capturing the thermal image, the moisture content at each location can be determined based on the temperature displayed, thereby determining the moisture distribution of the item.

[0064] When adjusting air-drying parameters based on moisture distribution, the items to be dried can be divided into zones. The zones can be determined based on the moisture distribution within the items. During drying, moisture distribution within the items may be uneven, with some areas containing less moisture and others containing more. Based on this distribution, the items can be divided into at least one zone to be dried.

[0065] Adjusting the air-drying process involves identifying the area with the highest moisture content on the items to be dried as the target area and blowing air towards it. The highest moisture content area has higher humidity and requires longer drying time. Blowing air towards this area can speed up drying efficiency and improve the uniformity of drying, ensuring that all items are dry after the drying process ends.

[0066] After blowing air toward the target area, the target area can be re-determined after each preset time interval to avoid the rest of the clothes being wet after the first target area is blown dry.

[0067] It's understandable that, when drying items, moisture in them will gradually move toward the bottom of the item under the influence of gravity, resulting in the highest moisture content at the bottom. Therefore, when dividing the drying area on the item, the temperature range of the thermal imaging can be combined to divide the item vertically into multiple drying areas to simplify the process.

[0068] For example, when drying clothes, they are typically stretched and hung on a clothesline. The collar, cuffs, and hem of a shirt are particularly vulnerable to drying. The collar and cuffs hold a high level of moisture due to the thickness and hardness of the material. The hem and cuffs, on the other hand, are located at the bottom of the garment and, due to the influence of gravity, hold a high level of moisture, making them difficult to dry. By vertically dividing the drying area, the collar, hem, and cuffs can be targeted for air drying, improving the drying effect.

[0069] It is understandable that the area to be dried on the drying object can be divided into two, three or more areas along the vertical direction. The specific number of areas to be dried can be set according to factors such as the moisture content distribution in the drying object and the size of the drying object.

[0070] Optionally, a database is stored in the clothes drying machine, and the database stores information such as the number of to-be-dried areas divided for different drying objects, the temperature threshold of each to-be-dried area, etc., for intelligent judgment.

[0071] In some embodiments, the drying areas of the items can be directly divided based on the type and / or size of the items, without considering the moisture distribution of the items. The database within the clothes drying machine sets the number of drying areas for each type of item. For example, a top can be divided into two drying areas, one for the top and one for the bottom; and three for pants, for the waist, crotch, and trouser legs. Smaller items such as towels can be assigned only one drying area; larger items such as sheets can be assigned two, three, or more drying areas.

[0072] Optionally, opposite sides of the items to be dried can be divided into areas to be dried. For example, the front of the garment can be divided into areas to be dried, and the back of the garment can also be divided into areas to be dried, so that both the front and back of the garment can be fully dried.

[0073] When the clothes drying machine is in use, the items to be dried will be randomly distributed along the length of the clothes drying rack according to the user's placement position. In order to ensure that each item to be dried can be fully dried, the clothes drying machine can divide the effective drying space along the length of the clothes drying rack, and divide the items to be dried in each drying area into separate areas. The clothes drying machine can adjust the blowing direction of each drying area separately.

[0074] In order to improve the drying effect of each area to be dried, after adjusting the blowing direction, the blowing mode and / or blowing parameters for each area to be dried can be obtained to adjust the working parameters of the clothes drying machine for each area to be dried to improve the drying effect of the clothes to be dried.

[0075] The blowing modes include a fixed-angle blowing mode and an oscillating blowing mode. The oscillating blowing mode includes a continuous oscillating blowing mode and an intermittent oscillating blowing mode. In the fixed-angle blowing mode, the blowing angle remains unchanged, and the air outlet covers the corresponding area to be dried. In the continuous oscillating blowing mode, the blowing angle changes continuously, oscillating back and forth within a certain angle range. In the intermittent oscillating blowing mode, the blowing angle is adjusted at regular intervals, so that the blowing angle changes intermittently within a certain angle range.

[0076] Optionally, a fixed-angle blowing mode or a swing blowing mode is selected according to the size, moisture content and / or location of the area to be dried.

[0077] For example, when the area to be dried covers the collar, the oscillating blowing mode can be selected so that the airflow can evenly cover the outside, inside, front and back of the collar to improve the drying effect; when the area to be dried is small, such as the crotch of pants, the fixed angle blowing mode can be used to concentrate on drying the crotch; when the area to be dried is large and the blowing coverage area is wide, the oscillating blowing mode can be used.

[0078] Among them, the blowing parameters include at least one of wind speed, blowing temperature, blowing swing angle and blowing swing period, so as to flexibly adjust the wind speed, blowing temperature, blowing swing angle and blowing swing period according to actual conditions.

[0079] Optionally, the blowing parameters can be obtained based on the size and location of the area to be dried, the moisture content within the drying area, and / or the rate of moisture reduction within the items being dried. For example, when the area to be dried is large, has a high moisture content, and / or is located at a location where moisture is difficult to evaporate, the wind speed, the blowing temperature, the blowing angle, and / or the blowing period can be increased to improve the drying effect of the area to be dried. Conversely, when the area to be dried is small, has a low moisture content, and / or is located at a location where moisture is easily evaporated, the wind speed, the blowing temperature, the blowing angle, and / or the blowing period can be reduced to avoid wasting resources.

[0080] Since the moisture distribution of the drying items is relatively uniform when they are first dried, the following steps are also performed after the air-drying process is started and before the moisture distribution of the drying items is obtained:

[0081] The air is blown in a swinging manner according to the preset blowing parameters, and the blowing range completely covers the items to be dried;

[0082] After the preset time has passed, the moisture distribution in the drying items is obtained.

[0083] When drying items, air is blown for a while to evaporate some of the moisture in the items. The remaining moisture then moves downward under gravity, reducing the moisture content in most areas of the items. The moisture distribution is then measured, allowing for targeted drying of areas with high moisture content. This improves drying efficiency and results, while minimizing resource waste.

[0084] Optionally, the preset blowing parameters may be parameters set before the clothes drying machine leaves the factory, or may be parameters set by the user.

[0085] To effectively control the air-drying cycle's duration, the program is shut down when the moisture distribution within the items meets the shutdown criteria. By monitoring the moisture distribution within the items and controlling the air-drying cycle's duration, we can improve drying efficiency while avoiding resource waste.

[0086] Optionally, the moisture distribution of the items being dried can be obtained using thermal imaging of the items. When the moisture content is low, the temperature of the items being dried is higher than when the moisture content is high. When the temperature (average or minimum) of the items being dried approaches the room temperature or the temperature of the items being dried indoors, the items can be considered dry and the air-drying process can be turned off.

[0087] Thermal imaging images can also obtain the temperature distribution of the items being dried to determine whether the items are dried evenly. If so, the air-drying program can be turned off.

[0088] Optionally, the closing condition may include that the temperature difference of the drying items is less than a preset value and / or the average temperature or the lowest temperature of the drying items is within a preset range. The preset range may be set according to the indoor temperature and light conditions.

[0089] In this embodiment, the moisture distribution of the clothes to be dried is adjusted through feedback with parameters such as the blowing angle and blowing time, and the blowing temperature is adjusted through feedback with the material and moisture distribution of the clothes, thereby realizing intelligent control and avoiding problems such as waste of resources, insufficient drying, and burns to the clothes to be dried.

[0090] In this embodiment, based on the moisture distribution in the clothes to be dried, the area to be dried with the highest moisture content in the clothes to be dried is determined as the target area, and the air-drying program is adjusted so that the clothes drying machine blows air toward the target area of the clothes to be dried. By air-drying the position with the highest humidity in the clothes to be dried, the drying efficiency of the position with the highest humidity can be accelerated, thereby improving the overall air-drying efficiency of the clothes to be dried.

[0091] Example 3

[0092] This embodiment provides a control method for a clothes drying machine, which is different from the second embodiment in that: Figure 3 As shown, after dividing the drying area on the drying items, the air-drying process is adjusted by blowing air toward the items along a preset trajectory, with the blowing time toward each drying area being proportional to the moisture content of the area. That is, areas with higher moisture content have longer drying times, while areas with lower moisture content have shorter drying times.

[0093] Through the above settings, resources can be reasonably utilized, and areas with high moisture content and difficult to dry can be blown for a longer time, while areas with low moisture content and easy to dry can be blown for a shorter time, which is beneficial to improving the drying effect and avoiding waste of resources.

[0094] Among them, the air drying time refers to the time length that the clothes drying machine provides airflow to the clothes to be dried; the preset trajectory can be from top to bottom or from bottom to top, or other trajectories can be used, which can be set according to actual needs.

[0095] In order to improve the drying effect of each area to be dried and reasonably control the blowing time in each area to be dried, the blowing mode and / or blowing parameters for blowing air to each area to be dried can be obtained to adjust the working parameters of the clothes drying machine for each area to be dried, thereby improving the drying effect of the clothes to be dried.

[0096] The blowing modes include a fixed-angle blowing mode and an oscillating blowing mode. The oscillating blowing mode includes a continuous oscillating blowing mode and an intermittent oscillating blowing mode. In the fixed-angle blowing mode, the blowing angle remains unchanged, and the air outlet covers the corresponding area to be dried. In the continuous oscillating blowing mode, the blowing angle changes continuously, oscillating back and forth within a certain angle range. In the intermittent oscillating blowing mode, the blowing angle is adjusted at regular intervals, so that the blowing angle changes intermittently within a certain angle range.

[0097] Optionally, the blowing modes of adjacent drying areas can be different or the same. For example, one drying area can be in a fixed-angle blowing mode, while the other drying area can be in a fixed-angle blowing mode, a continuous swing blowing mode, or an intermittent swing blowing mode.

[0098] In this embodiment, the blowing direction moves along a preset trajectory for the entire drying item, and the airflow can be blown sequentially to multiple drying areas along the preset trajectory. To save time, the blowing direction can reciprocate along the preset trajectory. That is, during the drying process, the blowing direction moves forward along the preset trajectory, then moves in the reverse direction, achieving a reciprocating swing.

[0099] When blowing air toward a certain area to be dried and selecting the swing blowing mode, the blowing direction can only swing in one direction; when the blowing direction moves in the opposite direction according to the preset trajectory, it will pass through the area to be dried again.

[0100] Optionally, the duration of blowing toward the areas to be dried may be controlled by controlling the duration of the blowing direction when it is directed toward different areas to be dried or the speed of change of the blowing angle.

[0101] Optionally, after passing each drying area, determine whether the closing condition is met. If the closing condition is met, close the air-drying program; if the closing condition is not met, continue to blow air to the next drying area to avoid wasting resources.

[0102] Optionally, the closing condition may include that the temperature difference of the drying items is less than a preset value and / or the average temperature or the lowest temperature of the drying items is within a preset range. The preset range may be set according to the indoor temperature and light conditions.

[0103] In this embodiment, the moisture distribution of the clothes to be dried is adjusted through feedback with parameters such as the blowing angle and blowing time, and the blowing temperature is adjusted through feedback with the material and moisture distribution of the clothes, thereby realizing intelligent control and avoiding problems such as waste of resources, insufficient drying, and burns to the clothes to be dried.

[0104] Example 4

[0105] like Figure 4As shown, this embodiment provides a control method for a clothes drying machine, which is further improved on the basis of the first embodiment. The control method includes:

[0106] After the air drying process is started, the blowing angle swings back and forth within the first angle range and the first cycle so that the blowing range completely covers the drying items in the vertical direction; at the same time, the infrared detection module is started to record the initial thermal imaging image of the drying items. The first angle range and the first cycle are factory settings.

[0107] After the air-drying program runs for the first time, a thermal imaging image of the article to be dried is obtained again, and the current moisture distribution in the article to be dried is obtained based on the thermal imaging image;

[0108] The clothes drying machine divides the clothes into an upper area and a lower area. Based on the moisture distribution, air is blown to the upper area or the lower area. When blowing air to the upper area, the blowing angle oscillates back and forth within a second angular range and a second cycle. When blowing air to the lower area, the blowing angle oscillates back and forth within a third angular range and a third cycle. Alternatively, the clothes drying machine can blow air to the upper and lower areas sequentially.

[0109] Among them, the second angle range, the second period, the third angle range and the third period can be intelligently selected according to the moisture distribution, or can be factory set values.

[0110] When the difference between the highest temperature and the lowest temperature in the thermal imaging image of the drying object is less than the set difference, the air drying program is turned off.

[0111] In this embodiment, the moisture distribution of the clothes to be dried is adjusted through feedback with parameters such as the blowing angle and blowing time, and the blowing temperature is adjusted through feedback with the material and moisture distribution of the clothes, thereby realizing intelligent control and avoiding problems such as waste of resources, insufficient drying, and burns to the clothes to be dried.

[0112] Example 5

[0113] This embodiment provides a control method for a clothes drying machine, which is further improved on the basis of the first embodiment. The control method includes:

[0114] After the air-drying process is activated, the air blowing angle oscillates back and forth within a first angle range and at a first cycle, ensuring that the air blowing range completely covers the items vertically. Simultaneously, the infrared detection module is activated to record an initial thermal image of the items. The first angle range and first cycle are factory defaults.

[0115] After the air-drying program runs for the first period of time, a thermal imaging image of the drying object is obtained again, and the current moisture distribution in the drying object is obtained based on the thermal imaging image of the drying object; at the same time, the thermal imaging image of the drying object obtained again is compared with the initial thermal imaging image, and the material of the drying object is obtained through the water loss rate of the drying object.

[0116] The clothes drying machine divides the clothes into an upper area and a lower area. Based on the moisture distribution, air is blown to the upper area or the lower area. When blowing air to the upper area, the blowing angle oscillates back and forth within a second angular range and a second cycle. When blowing air to the lower area, the blowing angle oscillates back and forth within a third angular range and a third cycle. Alternatively, the clothes drying machine can blow air to the upper and lower areas sequentially.

[0117] Among them, the second angle range, the second period, the third angle range and the third period can be intelligently selected according to the moisture distribution, or can be factory set values.

[0118] The blowing temperature and the power of the heating element are obtained based on the material of the clothes being dried to avoid damage to the clothes. For example, the materials of the clothes may include silk, cotton, linen, and chemical fiber. When the clothes are made of silk, the blowing temperature can be a first temperature and the power of the heating element can be the first power to avoid damage to the silk caused by excessively high blowing temperature; when the clothes are made of chemical fiber, the blowing temperature can be a second temperature and the power of the heating element can be a second power, the second temperature being higher than the first temperature and the second power being greater than the first power; when the clothes are made of cotton, the blowing temperature can be a third temperature and the power of the heating element can be a third power, the third temperature being higher than the first temperature and lower than the second temperature, the third power being higher than the first power and lower than the second power.

[0119] When the difference between the highest temperature and the lowest temperature in the thermal imaging image of the drying object is less than the set difference, the air drying program is turned off.

[0120] In this embodiment, the moisture distribution of the clothes to be dried is adjusted through feedback with parameters such as the blowing angle and blowing time, and the blowing temperature is adjusted through feedback with the material and moisture distribution of the clothes, thereby realizing intelligent control and avoiding problems such as waste of resources, insufficient drying, and burns to the clothes to be dried.
