Description

Technical Field

[0001] This application relates to the field of clothing drying technology, and in particular to a clothing drying device and a clothing drying control method. Background Technology

[0002] In related technologies, clothing drying equipment has a heating and air supply device installed on one or both sides of the drum axis. The heating and air supply device provides high-temperature drying gas to the drum. The high-temperature drying gas exchanges heat with the moisture in the clothes to form low-heat, high-humidity gas before being discharged.

[0003] As clothes dry, their moisture content decreases. Due to the movement of the lifting ribs on the drum and the drum's rotation, clothes usually don't fall off at the highest point of the drum. Instead, they rotate with the drum inside. Therefore, when clothes are almost dry, their position inside the drum is relatively fixed. This results in different heat exchange rates between the clothes and the hot air in different areas of the drum, leading to significant differences in the degree of drying and uneven drying.

[0074] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of this application will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art.

[0076] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed.

[0079] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0080] Clothes drying equipment is a drying device that dries damp clothes. During the drying process, the equipment controls a heating and air supply device to provide high-temperature drying gas to the drum. This high-temperature gas exchanges heat with the moisture in the clothes, forming low-heat, high-humidity gas before being discharged. However, as clothes dry, their moisture content decreases, resulting in lighter weight. The lifting ribs on the drum, combined with the drum's rapid rotation, mean that clothes usually don't fall off at the highest point of the drum but continue rotating with it. Therefore, when clothes are almost dry, most of them remain relatively stationary within the drum. This leads to inconsistent hot air volume and heat distribution, resulting in significant differences in the degree of drying in different areas of the drum. This uneven drying is especially noticeable when drying a large quantity of clothes or a mix of different types. Due to differences in fabric, absorbency, and moisture release characteristics, the difference in drying degree is even greater across different circumferential locations within the drum, making the uneven drying problem even more pronounced.

[0081] Therefore, this application provides a clothes drying device, a clothes drying control method applied to the clothes drying device, and related apparatus to improve the uniformity of clothes drying.

[0082] The following detailed description of the clothing drying equipment, clothing drying control method and related devices provided in this application, with reference to specific embodiments, is provided in detail.

[0083] Figure 1A front view of a clothes drying device according to an embodiment of this application is shown; Figure 2 A side view of a clothes drying device according to an embodiment of this application is shown; Figure 3 A block diagram of the electrical control system of a clothes drying apparatus according to an embodiment of this application is shown.

[0084] like Figures 1 to 3 As shown, the clothes drying equipment mainly includes a cabinet 101, a drum 102, multiple heating and air supply devices, a humidity detection device 103, a controller 104, and other necessary components.

[0085] The housing 101 contains a accommodating space that houses components such as the roller 102, the heating and air supply device, and the controller 104.

[0086] A front panel can be provided on the front side of the cabinet 101, and a clothes loading port is provided on the front panel, which is connected to the drum 102. When the clothes loading port is open, the user can put the clothes to be dried into the drum 102 through the clothes loading port, or take out the dried clothes from the drum 102.

[0087] A door can also be installed on one side of the clothing loading port on the front panel. The door is hinged to the front panel, and the clothing loading port can be opened or closed by rotating the door.

[0088] The drum 102 is rotatably mounted inside the housing 101. When clothes need to be dried, the drum 102 is driven to rotate, allowing the clothes to fully contact the hot air entering the drum 102, thereby achieving rapid drying. The drum 102 can be connected to the output shaft of the drive motor 105. When the clothes drying equipment is running the clothes drying program, the drive motor 105 drives the drum 102 to rotate.

[0089] The plurality of heating air supply devices include a plurality of first heating air supply devices 106 and at least one second heating air supply device 107.

[0090] Multiple first heating and air supply devices 106 are arranged at circumferential intervals along the roller 102. Each first heating and air supply device 106 can independently heat the air to obtain hot air and blow the hot air to the corresponding area of ​​the roller 102.

[0091] In one embodiment of this application, a plurality of first heating and air supply devices 106 are arranged at equal intervals along the circumference of the drum 102, thereby making the hot air blown towards each area of ​​the drum 102 in the circumference more evenly distributed, so that the clothes are dried more evenly in each area of ​​the drum 102 in the circumference.

[0092] Of course, in other embodiments, the plurality of first heating and air supply devices 106 may also be arranged at unequal intervals along the circumference of the roller 102.

[0093] In one embodiment of this application, the first heating and air supply device 106 includes a first heater and a first fan. The first heater heats the air, and the first fan accelerates the airflow speed to speed up the drying of clothes in the drum 102. The heating temperature of the first heater is adjustable to adjust the hot air temperature. Similarly, the rotation speed of the first fan is adjustable to adjust the airflow speed, thereby adjusting the speed of the hot air blown onto the drum 102.

[0094] Specifically, the first heater can be an electric heater.

[0095] The second heating and air supply device 107 is disposed on at least one side of the roller 102 along the axial direction. The second heating and air supply device 107 can independently heat the air to obtain hot air and blow the hot air into the roller 102 along the axial direction of the roller 102.

[0096] The number of second heating and air supply devices 107 can be one or more. In one embodiment of this application, the number of second heating and air supply devices 107 is multiple, and the multiple second heating and air supply devices 107 are spaced apart on one side of the roller 102 along the axial direction. By setting the second heating and air supply devices 107 on one side of the roller 102 along the axial direction, the layout structure of the second heating and air supply devices 107 is simple, and setting multiple second heating and air supply devices 107 can make the hot air blown to various positions of the roller 102 more evenly distributed.

[0097] In one embodiment of this application, a plurality of second heating and air supply devices 107 are equally spaced on one side of the roller 102 along the axial direction, thereby making the hot air blown to various positions of the roller 102 more evenly distributed, so as to make the clothes inside the roller 102 dry more evenly.

[0098] Of course, in other embodiments, the plurality of second heating and air supply devices 107 may also be arranged at unequal intervals on one or both sides of the roller 102 along the axial direction.

[0099] In one embodiment of this application, a plurality of second heating and air supply devices 107 are equally spaced on a first side along the axial direction of the roller 102, wherein the first side is the side of the roller 102 away from the front panel. Of course, the plurality of second heating and air supply devices 107 may also be equally spaced on a second side along the axial direction of the roller 102, which is understood to be the side of the roller 102 closer to the front panel.

[0100] It should be noted that in some embodiments, one or more second heating and air supply devices 107 may be provided on the first and second sides along the axial direction of the drum 102 to improve the uniformity of clothes drying along the axial direction of the drum 102.

[0101] In one embodiment of this application, the second heating and air supply device 107 includes a second heater and a second fan. The second heater heats the air, and the second fan accelerates the airflow speed to speed up the drying of clothes in the drum 102. The heating temperature of the second heater can be adjustable to adjust the hot air temperature; alternatively, the heating temperature of the second heater can be fixed. The rotation speed of the second fan is adjustable to adjust the airflow speed, thereby adjusting the speed of the hot air blown onto the drum 102.

[0102] Specifically, the second heater can be an electric heater.

[0103] In one embodiment of this application, the second heating and air supply device 107 is disposed on the first side along the axial direction of the roller 102, and the distance between the first heating and air supply device 106 and the first side is greater than the distance between the first heating and air supply device 106 and the second side, such as... Figure 2 As shown. A large distance is reserved between the first heating and air supply device 106 and the first side of the roller 102 where the second heating and air supply device 107 is axially arranged, which can prevent the clothes at the rear end of the roller 102 from being over-dried due to the combined action of the first heating and air supply device 106 and the second heating and air supply device 107.

[0104] The distance between the first heating and air supply device 106 and the first side can be the distance between the center of the air outlet of the first heating and air supply device 106 and the rear end of the roller 102. The distance between the first heating and air supply device 106 and the second side can be the distance between the center of the air outlet of the first heating and air supply device 106 and the front end of the roller 102.

[0105] In other embodiments, the second heating and air supply device 107 may be disposed on the first side in the axial direction of the drum 102, and the distance between the first heating and air supply device 106 and the first side may be equal to or less than the distance between the first heating and air supply device 106 and the second side.

[0106] Furthermore, in one embodiment of this application, the outlet air temperature of the first heating and air supply device 106 is higher than the outlet air temperature of the second heating and air supply device 107. That is, when both the first heating and air supply device 106 and the second heating and air supply device 107 are simultaneously activated for heating, the air temperature (hot air temperature) after being heated by the first heating and air supply device 106 is higher than the air temperature (hot air temperature) after being heated by the second heating and air supply device 107. This prevents the clothes at the end of the roller 102 closest to the second heating and air supply device 107 (rear end area) from becoming over-dried.

[0107] Of course, the outlet temperature of the first heating and air supply device 106 can also be equal to the outlet temperature of the second heating and air supply device 107, or even the outlet temperature of the first heating and air supply device 106 can be less than the outlet temperature of the second heating and air supply device 107.

[0108] Understandably, a circulating air duct is also required inside the housing 101. The circulating air duct includes multiple air supply ducts (not shown in the figure). Multiple first heating air supply devices 106 and second heating air supply devices 107 are respectively installed in each air supply duct and are installed in a one-to-one correspondence with the air supply ducts. The first heating air supply devices 106 and the second heating air supply devices 107 heat the air entering the air supply duct to form hot air.

[0109] Each air supply duct's inlet end connects to the exhaust port of the roller 102, and each air supply duct's outlet end connects to the inlet of the roller 102. The roller 102 has multiple inlets corresponding one-to-one with the first heating air supply device 106 and the second heating air supply device 107. That is, the multiple inlets are equally spaced along the circumference of the roller 102 and equally spaced on one side in the axial direction. The hot air generated by the first heating air supply device 106 and the second heating air supply device 107 in the air supply duct enters the roller 102 through the corresponding inlets. After heat exchange with the clothing, the hot air entering the roller 102 is discharged through the exhaust port of the roller 102 and enters the air supply duct through the inlet end of the air supply duct. After being heated again by the first heating air supply device 106 and the second heating air supply device 107, it forms hot air.

[0110] The circulating air duct may also include an air inlet duct 108, the air inlet end of which is connected to the exhaust port of the roller 102, and the air outlet end of which is connected to the air inlet ends of multiple air supply ducts. The air outlet ends of each air supply duct are connected to the air inlet of the roller 102. That is, the air inlet duct 108 enables the connection between multiple air supply ducts and the roller 102 on the exhaust path of the roller 102. It is not necessary to set each air supply duct to be connected to the exhaust port of the roller 102 separately. The layout of the circulating air duct is simple and easy to implement.

[0111] In some embodiments, the clothes drying equipment may further include a heat pump system. For example, the air discharged from the drum 102 is heated by the heat pump system and then enters each air supply duct. The first heating air supply device 106 and the second heating air supply device 107 in each air supply duct heat the air again and then send it into the drum 102 through the air outlet of the air supply duct.

[0112] It should be noted that each of the first heating and air supply devices 106 may also include an air supply duct, with the first heater and the first fan arranged in the corresponding air supply duct; each of the second heating and air supply devices 107 may include an air supply duct, with the second heater and the second fan arranged in the corresponding air supply duct.

[0113] A humidity detection device 103 is installed inside the drum 102. The humidity detection device 103 is used to detect the humidity value in the drum 102, thereby determining the dryness of the clothes in the drum 102.

[0114] The humidity detection device 103 may only have a humidity detection function, or it may have a temperature detection function integrated on the basis of having a humidity detection function, that is, a temperature and humidity detection device that integrates a humidity sensor and a temperature sensor.

[0115] In one embodiment of this application, each pair of adjacent first heating and air supply devices 106 and one second heating and air supply device 107 defines a drying zone. The second heating and air supply device 107 is circumferentially located between the two adjacent first heating and air supply devices 106. Each drying zone is equipped with at least one humidity detection device 103. The humidity detection device 103 detects the humidity value of the corresponding drying zone, enabling zoned detection of the clothing's humidity value. Furthermore, based on the drying status of the clothing in each drying zone of the drum 102, the hot air temperature and / or hot air velocity provided by each heating and air supply device can be controlled accordingly, achieving targeted drying of clothing in different zones, thereby improving the uniformity of clothing drying.

[0116] In one embodiment of this application, each drying zone is provided with multiple humidity detection devices 103. The humidity value of the corresponding drying zone is obtained based on the humidity values ​​detected by the multiple humidity detection devices 103. For example, the average of the humidity values ​​detected by the multiple humidity detection devices 103 is calculated to obtain the humidity value of the corresponding drying zone, making the humidity value detection of the drying zone more accurate. Specifically, in each drying zone, the multiple humidity detection devices 103 are arranged at axial intervals along the roller 102.

[0117] In one embodiment of this application, each drying zone is provided with a lifting rib 109 extending axially along the drum 102. The lifting rib 109 is fixed to the inner wall of the drum 102, and a humidity detection device 103 is provided on the lifting rib 109. During the clothes drying program, the lifting rib 109 can agitate the clothes to change their position within the drum 102, improving the uniformity of drying and preventing the clothes from tangling. The humidity detection device 103, located on the lifting rib 109, can make full contact with the clothes, thus improving the accuracy of humidity detection.

[0118] Specifically, the lifting rib 109 is positioned in the middle of two adjacent first heating and air supply devices 106, that is, the lifting rib 109 is positioned in the middle of the drying area. Multiple humidity detection devices 103 are spaced apart on the lifting rib 109.

[0119] In one example, four first heating and air supply devices 106 are equally spaced along the circumference of the drum 102, and four second heating and air supply devices 107 are equally spaced on the first side of the drum 102. In the circumferential direction, each second heating and air supply device 107 is located between two adjacent first heating and air supply devices 106. The four first heating and air supply devices 106 and the four second heating and air supply devices 107 divide the internal space of the drum 102 into four drying zones. A lifting rib 109 extending axially along the drum 102 is provided at the center of each of the four drying zones. The side of each lifting rib 109 furthest from the front panel (rear side) is opposite to a second heating and air supply device 107.

[0120] The controller 104 is responsible for receiving signals from various sensors in the clothing processing equipment and running programs. It processes the feedback signals from each sensor in combination with preset program logic to control the operation of various components of the clothing drying equipment, such as the coordinated operation of the drive motor 105 that controls the rotation of the drive drum 102, the first heating and air supply device 106, and the second heating and air supply device 107.

[0121] The controller 104 includes one or more processors and a memory, wherein the memory is used to store one or more programs, and when the one or more programs are executed by one or more processors, the clothes drying device implements the following clothes drying control method.

[0122] Figure 4 A flowchart of a clothes drying control method according to an embodiment of this application is shown. (See attached document.) Figure 4 As shown, the clothes drying control method includes at least steps S410 to S440, which are described in detail below:

[0123] In step S410, multiple heating and air supply devices are controlled to run for a first preset time, and then the judgment step, namely step S420, is entered.

[0124] That is, in step S410, all the first heating and air supply devices and the second heating and air supply devices are controlled to run for a first preset time.

[0125] The first preset time is set according to actual needs. In one embodiment of this application, the first preset time is equal to the drying time corresponding to the type of clothing with the shortest required drying time among the clothes to be dried.

[0126] During a single clothes drying process, there may be various types of clothes in the drum. The first preset time is equal to the drying time corresponding to the type of clothes that requires the shortest drying time. At this time, clothes of the same type as those selected by the program may be completely dry, but other types of clothes may not be completely dry. At this time, the clothes in the drum are generally relatively dry, and most of them will move in a circular motion with the drum under the action of the lifting ribs. The position of the clothes in the drum is basically fixed. If the subsequent steps determine that the drying result does not meet the drying conditions, then zone drying can be performed to dry the clothes in the drying area with higher humidity, thereby improving the uniformity of drying and preventing some types of clothes from being over-dried.

[0127] In some embodiments, the first preset time may be slightly longer than the drying time corresponding to the type of clothing with the shortest required drying time among the clothes to be dried. Alternatively, the first preset time may be determined based on other factors, and is not limited to the drying time corresponding to the type of clothing with the shortest required drying time among the clothes to be dried.

[0128] In step S420, drying is determined based on the drying conditions. If the drying result does not meet the drying conditions, the process proceeds to the zone drying step, i.e., step S430. If the drying result meets the drying conditions, the process proceeds directly to step S440 to further end the drying process.

[0129] There are various methods for determining dryness. For example, a humidity sensor can be installed at the exhaust vent of the roller to detect the humidity of the air discharged from the roller. In step S420, dryness is determined based on the humidity of the air discharged from the roller and a preset humidity level. If the humidity of the air discharged from the roller is less than the preset humidity, the dryness determination result meets the dryness determination condition; if the humidity of the air discharged from the roller is greater than or equal to the preset humidity, the dryness determination result does not meet the dryness determination condition. Alternatively, a temperature detection device installed on the lifting ribs can be used to detect the humidity value of the clothing. In step S420, dryness is determined based on the detected humidity value of the clothing and a preset humidity value. If the detected humidity value of the clothing is less than the preset humidity value, the dryness determination result meets the dryness determination condition; if the detected humidity value of the clothing is greater than or equal to the preset humidity value, the dryness determination result does not meet the dryness determination condition. Alternatively, a gravity sensor can be set up to weigh and detect the clothes inside the drum. In step S420, the dryness is judged based on the detected weight of the clothes and the preset weight. If the detected weight of the clothes is less than the preset weight, the dryness result meets the dryness condition. If the detected weight of the clothes is greater than or equal to the preset weight, the dryness result does not meet the dryness condition.

[0130] In step S430, the drying area corresponding to the maximum humidity is obtained. The drying area corresponding to the maximum humidity is the target drying area. When the maximum humidity meets the preset conditions, multiple heating and air supply devices are controlled to make the hot air temperature and / or hot air velocity provided to the target drying area greater than that of the drying areas outside the target drying area. When the maximum humidity does not meet the preset conditions, the process returns to step S420.

[0131] In one embodiment of this application, when the maximum humidity meets a preset condition, the two first heating and air supply devices and one second heating and air supply device corresponding to the target drying area are controlled to operate in a first mode, while the first and second heating and air supply devices corresponding to drying areas outside the target drying area are controlled to operate in a second mode. In the first mode, the hot air temperature and / or hot air velocity provided by the first and second heating and air supply devices are greater than the hot air temperature and / or hot air volume provided in the second mode. By controlling the first and second heating and air supply devices corresponding to the target drying area to provide higher hot air temperatures and / or greater hot air volumes, the drying speed of clothes in the target drying area can be accelerated, thereby making the dryness of clothes in different drying areas more similar.

[0132] Specifically, in the first mode, the hot air temperature and velocity provided by the first heating and air supply device are greater than those provided in the second mode. In the first mode, the hot air temperature provided by the second heating and air supply device is equal to that provided in the second mode, and the hot air volume provided by the second heating and air supply device is greater than that provided in the second mode. Of course, specific embodiments are not limited to this; for example, in the first mode, both the hot air temperature and the hot air volume provided by the second heating and air supply device are greater than those provided in the second mode.

[0133] In one example, the first mode is the operating mode of the first heating and air supply device and the second heating and air supply device in step S410. That is, when the maximum humidity meets the preset conditions, the first heating and air supply device and the second heating and air supply device corresponding to the drying area outside the target drying area are controlled to continue to operate in the current mode. At the same time, the two first heating and air supply devices and one second heating and air supply device corresponding to the target drying area are controlled to increase the hot air temperature and / or hot air volume. The control logic is simple and easy to implement.

[0134] Of course, in some embodiments, when the maximum humidity meets a preset condition, the first and second heating and air supply devices corresponding to the drying area outside the target drying area may be controlled to reduce the hot air temperature and / or hot air volume, while the two first heating and air supply devices and one second heating and air supply device corresponding to the target drying area may continue to operate in the current mode, or the hot air temperature and / or hot air volume may be increased. Alternatively, the first and second heating and air supply devices corresponding to the drying area outside the target drying area may be controlled to stop operating, while the two first heating and air supply devices and one second heating and air supply device corresponding to the target drying area may continue to operate in the current mode, or the hot air temperature and / or hot air volume may be increased.

[0135] In one embodiment of this application, the maximum humidity value meets the preset condition as follows: the humidity difference between the maximum humidity value and the minimum humidity value reaches or exceeds a preset difference threshold, and the minimum humidity value is the humidity value corresponding to the drying area with the lowest humidity. Correspondingly, the maximum humidity value does not meet the preset condition as follows: the humidity difference between the maximum humidity value and the minimum humidity value is below a preset difference threshold.

[0136] That is, in step S430, when the humidity difference between the humidity value of the drying area corresponding to the maximum humidity value and the humidity value of the drying area corresponding to the minimum humidity value reaches a preset difference threshold, the two first heating and air supply devices and one second heating and air supply device corresponding to the target drying area are controlled to operate in the first mode, and the first heating and air supply devices and the second heating and air supply devices corresponding to the drying areas other than the target drying area are controlled to operate in the second mode. When the humidity difference between the humidity value of the drying area corresponding to the maximum humidity value and the humidity value of the drying area corresponding to the minimum humidity value is below the preset difference threshold, the process returns to step S420.

[0137] If the humidity difference between the drying area corresponding to the maximum humidity and the drying area corresponding to the minimum humidity exceeds a preset threshold, it indicates a large difference in the dryness of the clothes in each drying area. In this case, by controlling the two first heating and air supply devices and one second heating and air supply device corresponding to the drying area corresponding to the maximum humidity (target drying area) to operate in the first mode, the drying speed of the clothes in the drying area corresponding to the maximum humidity is specifically accelerated. If the humidity difference between the drying area corresponding to the maximum humidity and the drying area corresponding to the minimum humidity is below the preset threshold, it indicates a small difference in the dryness of the clothes in each drying area, and therefore there is no need to specifically accelerate the drying speed of the clothes in the drying area corresponding to the maximum humidity.

[0138] The preset difference threshold is a pre-set value that can be flexibly set based on specific circumstances.

[0139] In one embodiment of this application, in step S430, while controlling the two first heating and air supply devices and one second heating and air supply device corresponding to the target drying area to operate in a first mode, the temperature of the target drying area is also acquired. If the temperature of the target drying area reaches above the first temperature, the two first heating and air supply devices corresponding to the target drying area are controlled to stop heating until the temperature of the target drying area drops below the second temperature.

[0140] The first temperature is a preset maximum allowable temperature. When the temperature of the target drying area reaches or exceeds the first temperature, the two first heating and air supply devices corresponding to the target drying area are controlled to stop heating, which can prevent the temperature of the target drying area from being too high and damaging the clothes.

[0141] The second temperature is the average temperature of the drying area outside the target drying area. That is, after the temperature in the target drying area drops to the average temperature of the drying area outside the target drying area, the two first heating and air supply devices corresponding to the target drying area are restarted for heating. Of course, the second temperature is not limited to being set to the average temperature of the drying area outside the target drying area; for example, the second temperature can be a pre-set reasonable temperature value.

[0142] In one embodiment of this application, each drying zone is provided with multiple humidity detection devices. In step S430, multiple humidity information detected by multiple humidity detection devices in the drying zone within a third preset time period is obtained, the average value of the humidity information detected by multiple humidity detection devices is calculated, and the humidity value corresponding to the drying zone is obtained, that is, the humidity value of the clothes in the drying zone.

[0143] By setting up multiple humidity detection devices in each drying zone, the humidity of clothes at different locations in each drying zone can be detected during the drying process, and the average value of the humidity information detected by multiple humidity detection devices can be calculated as the humidity value corresponding to the drying zone, making the humidity value detection results of the drying zone more accurate.

[0144] If the drying result still does not meet the drying conditions after returning to step S420, the process will proceed to the zone drying step again, i.e., step S430.

[0145] In step S440, multiple first heating and air supply devices are controlled to stop operating; multiple second heating and air supply devices are controlled to stop heating and increase the air speed to the target air speed, and after maintaining the target air speed for a second preset time, multiple second heating and air supply devices are controlled to stop operating.

[0146] The target wind speed is a preset wind speed value, which is greater than the wind speed of the second heating and air supply device in the first mode. The second preset time is a preset value that can be flexibly configured according to actual conditions.

[0147] After the drying results meet the drying conditions, before ending the drying process, control multiple secondary heating and air supply devices to stop heating and increase the air speed. This can fully blow out the lint remaining in the drum, while preventing the clothes from suddenly cooling down and causing wrinkles.

[0148] Of course, in other embodiments, after the drying result meets the drying conditions and before the drying process ends, multiple first heating and air supply devices and second heating and air supply devices can be directly controlled to stop operating.

[0149] It should be noted that after the drying program is started and before it is ended, the drum is controlled to run at the speed set by the program; that is, in the aforementioned steps S410 to S430, the drum is controlled to run at the speed set by the program, and in step S440, the drum is controlled to gradually reduce the speed until it stops rotating.

[0150] This application provides a clothing drying equipment with multiple first heating and air supply devices and at least one second heating and air supply device. The multiple first heating and air supply devices are arranged at circumferential intervals along the drum, so that hot air can be provided to the corresponding areas in the drum in the circumferential direction. The second heating and air supply device is arranged on at least one side of the drum in the axial direction, so that hot air can be provided to the drum in the circumferential direction. This enables the hot air to be evenly provided to all areas in the drum, thereby achieving uniform drying of clothes throughout the drying process and improving the drying speed. Each pair of adjacent first heating and air supply devices and one second heating and air supply device defines a drying zone. The heating and air supply devices can provide hot air to the corresponding drying zone in the drum. When drying clothes, multiple heating and air supply devices are first controlled to operate. After the main drying step is executed for the first preset time, a drying judgment is performed. If the drying judgment result does not meet the drying judgment conditions, the target drying zone corresponding to the maximum humidity is further obtained. When the maximum humidity meets the preset conditions, multiple heating and air supply devices are controlled to make the hot air temperature and / or hot air velocity provided to the target drying zone greater than that of the drying zones outside the target drying zone, thereby drying the clothes in the target drying zone in a targeted manner, thereby improving the uniformity of drying clothes. Even when drying a large amount of clothes or a mixture of different types of clothes, a relatively ideal drying effect can be obtained, greatly improving user satisfaction.

[0151] The main program and the partition drying program of this application will be further described in detail below based on specific embodiments.

[0152] Figure 5 A flowchart of the main program of one embodiment of this application is shown. The main program includes a main drying step and a drying determination step. (See attached diagram.) Figure 5 As shown, the main program includes steps S510 to S550, which are described in detail below:

[0153] In step S510, the main program is started in response to the drying program selected by the user.

[0154] The drying program selected by the user includes the drying time corresponding to the type of clothing that requires the shortest drying time.

[0155] In step S520, the roller is controlled to rotate along a preset direction at a preset speed R1, all first heating and air supply devices are controlled to heat up to a preset temperature T0 and run at a preset speed RP, and all second heating and air supply devices are controlled to heat up to a preset temperature T and run at a preset speed R0.

[0156] The preset rotation speed R1, preset temperature T0, preset rotation speed RP, preset temperature T, and preset rotation speed R0 can be determined based on the drying program selected by the user. The higher the temperature of the heating and air supply device, the higher the temperature of the generated hot air; the higher the rotation speed of the heating and air supply device, the greater the wind speed of the generated hot air.

[0157] In step S530, the main program running time is calculated, and it is determined whether the main program running time has reached the drying time corresponding to the type of clothing with the shortest required drying time among the clothes to be dried. If yes, proceed to step S540; otherwise, continue to maintain the current running state.

[0158] The main program running time is also the running time of the first heating and air supply device and the second heating and air supply device.

[0159] In step S540, drying is performed based on the drying conditions. If the drying result does not meet the drying conditions, the process proceeds to the zone drying procedure. If the drying result meets the drying conditions, the process proceeds to step S550.

[0160] When the main program runs for the time required to dry the type of clothing with the shortest drying time, the clothing of the same type as the selected program may be completely dry, but other types of clothing may not be completely dry (for example, the user selects a shirt as the drying program, but there are still cotton clothes, sweaters, and other types of clothing in the drum). By executing step S540, it is determined whether a zone drying program needs to be executed further.

[0161] In step S550, all first heating and air supply devices are controlled to stop heating and stop rotating (i.e., stop running), and all second heating and air supply devices are controlled to gradually reduce the temperature while increasing the rotation speed to the maximum value RMM, and stop rotating after a preset running time PT, while the drum is controlled to stop rotating.

[0162] Then, the drying process ends.

[0163] Figure 6A flowchart of a partitioned drying process according to an embodiment of this application is shown. This partitioned drying process is also the partitioned drying step in this application. See reference. Figure 6 As shown, the partition drying process includes steps S610 to S670, which are described in detail below:

[0164] In step S610, the zone drying program is initiated.

[0165] In step S620, the humidity detection device in each drying zone is controlled to perform humidity detection.

[0166] In step S630, each humidity detection device is controlled to perform N humidity detections within a preset time period ts, and the average value of the humidity information of the N humidity detections for each drying area is calculated as the humidity value corresponding to the drying area, and the humidity difference between the maximum and minimum humidity values ​​is further obtained.

[0167] Among them, the preset time period ts is the aforementioned third preset time, the maximum humidity value is the average maximum value of the humidity information, and the minimum humidity value is the average minimum value of the humidity information.

[0168] In this embodiment, the drying area corresponding to the maximum humidity is the drying area corresponding to the first heating and air supply devices H1 and H2 and the second heating and air supply device W1.

[0169] In step S640, it is determined whether the difference between the maximum and minimum humidity values ​​is greater than the preset difference threshold δH. If so, proceed to step S650; otherwise, end the partition drying program and return to the main program for drying judgment, which is the aforementioned step S540.

[0170] In step S650, the first heating and air supply devices H1 and H2 are controlled to heat up to a preset temperature T1 and increase their rotation speed to a preset speed RX (i.e., increase the air volume), while the second heating and air supply device W1 is controlled to increase its rotation speed to a preset speed RM (i.e., increase the air volume). During this process, the humidity detection device is controlled to detect the temperature of each drying zone. If the temperature of the drying zone corresponding to the first heating and air supply devices H1 and H2 does not exceed the preset maximum temperature (i.e., the aforementioned first temperature), the process proceeds directly to step S670; otherwise, the process proceeds to step S660.

[0171] In step S660, the first heating and air supply devices H1 and H2 are controlled to stop heating until the temperature of the corresponding drying area drops to the average temperature of other drying areas, and then the first heating and air supply devices H1 and H2 are controlled to start heating again.

[0172] In step S670, the preset time period ts is maintained, and then the process returns to step S640.

[0173] That is, while controlling the first heating and air supply devices H1 and H2 to perform zoned drying, the next humidity detection is initiated. At this time, the next humidity detection and the first zoned drying are completed simultaneously.

[0174] After returning to step S640, if the difference between the maximum and minimum humidity values ​​is greater than the preset difference threshold δH, proceed to step S650 again. If the difference between the maximum and minimum humidity values ​​is less than the preset difference threshold δH, return to the main program for judgment, which is the aforementioned step S540.

[0175] Corresponding to the aforementioned clothing drying control method, this application also provides a clothing drying control device.

[0176] See Figure 7 , Figure 7 A block diagram of a clothes drying control device according to an embodiment of this application is shown. This clothes drying control device can be applied to the controller of a clothes drying equipment to perform... Figures 4 to 6 All or part of the steps of any of the illustrated clothes drying control methods. For example... Figure 7 As shown, the device 700 includes, but is not limited to: a first control module 701, a dryness detection module 702, a second control module 703, a temperature acquisition module 704, a third control module 705, and a humidity acquisition module 706.

[0177] The first control module 701 is used to execute the main drying step, which includes controlling multiple heating and air supply devices to run for a first preset time.

[0178] In some embodiments of this application, based on the aforementioned scheme, the first preset time is greater than or equal to the drying time corresponding to the type of clothing with the shortest required drying time among the clothes to be dried.

[0179] The stemming module 702 is used to perform stemming steps to perform stemming based on stemming conditions.

[0180] The second control module 703 is used to execute a zoned drying step when the drying result does not meet the drying conditions. The zoned drying step includes: obtaining the drying area corresponding to the maximum humidity value, the drying area corresponding to the maximum humidity value is the target drying area, controlling multiple heating and air supply devices when the maximum humidity value meets the preset conditions, so that the hot air temperature and / or hot air velocity provided to the target drying area is greater than that of the drying areas outside the target drying area; and causing the drying module 702 to execute the drying step when the maximum humidity value does not meet the preset conditions.

[0181] In some embodiments of this application, based on the aforementioned scheme, the maximum humidity value meeting the preset conditions includes: the humidity difference between the maximum humidity value and the minimum humidity value reaches or exceeds a preset difference threshold, and the minimum humidity value is the humidity value corresponding to the drying area with the lowest humidity; correspondingly, the maximum humidity value not meeting the preset conditions includes: the humidity difference between the maximum humidity value and the minimum humidity value is below a preset difference threshold.

[0182] In some embodiments of this application, based on the aforementioned scheme, the second control module 703 is configured to control the two first heating and air supply devices and the one second heating and air supply device corresponding to the target drying area to operate in a first mode when the maximum humidity value meets the preset conditions, and to control the first heating and air supply device and the second heating and air supply device corresponding to the drying area outside the target drying area to operate in a second mode.

[0183] In the first mode, the hot air temperature and / or hot air velocity provided by the first heating and air supply device and the second heating and air supply device are greater than the hot air temperature and / or hot air volume provided in the second mode.

[0184] In some embodiments of this application, the device 700 further includes a temperature acquisition module 704. The temperature acquisition module 704 is used to acquire the temperature of the target drying area when the two first heating and air supply devices and one second heating and air supply device corresponding to the target drying area are operated in a first mode by the second control module 703. The second control module 703 is configured to control the two first heating and air supply devices corresponding to the target drying area to stop heating if the temperature of the target drying area reaches or exceeds a first temperature, until the temperature of the target drying area drops below a second temperature. The second temperature is the average temperature of the drying areas outside the target drying area.

[0185] In some embodiments of this application, the device 700 further includes a third control module 705, which is used to control multiple first heating and air supply devices to stop operating after the judgment result meets the judgment condition; control multiple second heating and air supply devices to stop heating and increase the wind speed to the target wind speed, and control multiple second heating and air supply devices to stop operating after maintaining the target wind speed for a second preset time.

[0186] In some embodiments of this application, based on the aforementioned scheme, each drying area is provided with multiple humidity detection devices. The device 700 further includes a humidity acquisition module 706, which is used to acquire multiple humidity information detected by multiple humidity detection devices in the drying area within a third preset time period, and calculate the average value of the humidity information detected by multiple humidity detection devices to obtain the humidity value corresponding to the drying area.

[0187] The specific implementation process of the functions and roles of each module in the above-mentioned device 700 can be found in the implementation process of the corresponding steps in the above-mentioned clothing drying control method, and will not be repeated here.

[0188] Corresponding to the aforementioned clothes drying control method, this application also provides an electronic device, which can be applied in a clothes drying device, such as a controller for the clothes drying device, to perform...
