DETAILED DESCRIPTION

[0023] The following describes the embodiments of the present application in conjunction with the accompanying drawings. It should be understood that the embodiments described below in conjunction with the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

[0024] Those skilled in the art will understand that, unless otherwise stated, the terms "said" and "the" used herein may also include plural forms. It should be further understood that the term "including" used in the specification of this application refers to the presence of the described features, integers, steps, operations, elements and / or components, but does not exclude the implementation of other features, information, data, steps, operations, elements, components and / or combinations thereof supported by the technical field. The term "and / or" used herein refers to at least one of the items defined by the term, for example, "A and / or B" can be implemented as "A", or as "B", or as "A and B".

[0025] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0026] refer to Figures 1 to 4 The present application provides a self-circulating drying system, which includes a hot air blower 1 and a guide fan 2 arranged at a distance, and a drying area 3 is formed between the hot air blower 1 and the guide fan 2. The hot air blower 1 and the guide fan 2 guide each other to form a circulating air supply channel in the drying area 3, and the drying area 3 is maintained in an open mode while ensuring that the hot air is fully utilized for drying. The self-circulating drying system of the present application is suitable for being configured in an electric clothes drying machine. Generally speaking, the electric clothes drying machine includes a main unit 5 and a drying component 6 controlled by the main unit 5. The hot air blower 1 can be configured at the drying component 6 to form a bottom-mounted drying component, and the guide fan 2 is correspondingly configured at the main unit 5; another possible implementation method is to swap the positions of the hot air blower 1 and the guide fan 2, which can also form a drying area 3 with a circulating air supply channel. In other implementation methods, the self-circulating drying system of the present application can be installed in other equipment that requires air-heat drying. In addition, the hot air blower 1 and the guide fan 2 can be arranged on a horizontal plane or a non-vertical plane.

[0027] refer to Figures 1-3, this embodiment adopts a hot air blower 1 with a longitudinal structure, which can expand the air supply range of hot air by extending in the longitudinal direction, and is particularly suitable for application in electric clothes drying machines. Optionally, the hot air blower 1 includes a hood 11 and a heating body 12 and a first fan 13 accommodated in the hood 11, wherein the hood 11 is provided with an upward air outlet 113, and the air inlet 114 of the hood 11 is preferably provided at a position that is not coplanar with the air outlet 113. The air inlet 114 of this embodiment is opened on both sides or one side of the longitudinal length of the hood 11. Further, on the basis of the foregoing, the first fan 13 is arranged close to the air inlet 114, and a heating body is provided on the air inlet channel of the hot air blower 1, so that the air flowing through the heating body is heated into hot air and then sent out from the air outlet 113. For ease of assembly, the air hood 11 can be configured to include an upper cover 111 and a lower cover 112 that overlap each other. The upper cover 111 is provided with an air outlet 113, and the lower cover 112 or an air inlet 114 is provided near the junction line between the upper cover 111 and the lower cover 112. Arranging the air inlet 114 and the air outlet 113 in a non-coplanar manner can help increase the air output of the hot air blower 1 and improve the drying effect.

[0028] In other embodiments, when the hot air blower 1 and the guide fan 2 are not arranged vertically, the air outlet 113 of the hot air blower 1 should be directed toward the guide fan 2. Preferably, the air outlet 113 of the hot air blower 1 should be directed toward the air inlet 114 of the guide fan 2, so that the guide fan 2 can play a guiding role in the open space. The air cover 11 of the hot air blower 1 can also adopt an outer contour with other shapes, and the air supply range can be covered by coordinating the spatial position or coordinating multiple hot air blowers 1 to achieve coverage.

[0029] refer to Figure 1 、 24. The guide fan 2 of this embodiment includes a duct member 21 and a second fan 22 accommodated in the duct member 21, wherein the duct member 21 is provided with an air inlet slot 214 and an air outlet slot 215 facing the hot air blower 1. Preferably, the air inlet slot 214 and the air outlet slot 215 can be arranged in the same plane to shorten the distance of the air supply channel turning and reduce the loss of hot air. In a possible embodiment, the duct member 21 includes a longitudinal bottom plate 211 and side plates 212 spaced apart on both sides of the longitudinal bottom plate 211. The gaps between the side plates 212 and the bottom plate 211 are respectively configured as the air inlet slot 214 and the air outlet slot 215. Furthermore, end plates 213 can be provided at both longitudinal ends of the duct member 21, and the end plates 213 are respectively connected to the bottom plate 211 and the side plates 212. Thus, the duct member 21 becomes an integrated structure, which is convenient for assembly. The upper ends of the two side panels 212 are not sealed, forming mounting slots 216 for receiving the second fans 22. If space permits, two or more second fans 22 can be arranged along the longitudinal axis of the bottom plate 211, with their air inlet sides aligned with the air inlet slots 214 and their air outlet sides aligned with the air outlet slots 215. The second fans 22 draw in the hot air delivered from the hot air blower 1 through the air inlet slots 214 and blow it out through the air outlet slots 215, directing the hot air back toward the hot air blower 1. The hot air blower 1 can then re-inhale and heat the hot air blown out by the guide fan 2 and the surrounding air, thereby reducing the extent of air heating and achieving the effect of saving electricity. Furthermore, the cross-sectional shape of the side panel 212 at the air outlet slot 215 can be optimized to conform to fluid mechanics, reduce wind resistance and reduce noise; movable swing blades (not shown) can also be provided outside the air inlet slot 214 and / or the air outlet slot 215 to adjust the wind direction to better adapt to the size and volume of the dried objects.

[0030] refer to Figures 1-3The hot air blower 1 and the guide fan 2 are arranged along the longitudinal axis of the electric clothes drying machine, so that the drying area 3 can at least cover the lower projection surface of the main unit 5. As mentioned above, the air supply width can be adjusted by setting the swing blades to adjust the horizontal coverage of the drying area 3. Furthermore, a connecting rod 4 can be arranged between the hot air blower 1 and the guide fan 2, and the vertical coverage of the drying area 3 is limited by the length of the connecting rod 4. Optionally, two parallel connecting rods 4 are respectively connected to the longitudinal ends of the hot air blower 1 and the main unit 5, so that the hot air blower 1 is suspended below the main unit 5, and the connecting rods 4 can also be used to bury wires so that the hot air blower 1 draws power from the main unit 5. Furthermore, if the hot air blower 1 is facing the central axis of the main unit 5, the main unit 5 can be provided with two mirror-symmetrical guide fans 2, so that the air inlet slot 214 is in the center and the air outlet slots 215 are separated on both sides. Therefore, the circulating air supply channel of the present application is as follows: the hot air starting from the hot air blower 1 below is blown upward, flows through the inner side of the dried object from bottom to top, and reaches the guide fan 2. The guide fan 2 introduces the hot air from its air inlet slot 214 and blows it downward from its air outlet slot 215, flowing from top to bottom through the outside of the dried object. The residual hot air and the surrounding air enter the hot air blower 1 from the air inlet 114 located on the side of the hot air blower 1, are heated again and blown out, and the hot air continues to circulate in the above manner, and forms two circulating air supply channels in the drying area 3.

[0031] In other embodiments, the hot air blower 1 may be offset below the main unit 5, and / or only one guide fan 2 may be used.

[0032] refer to Figure 5In another possible embodiment, in order to meet the drying requirements of difficult-to-dry areas such as collars, cuffs, or underarms of clothing, the hot air blower 1 and the guide fan 2 can be improved to form a circulating air supply channel that is different from the above-mentioned embodiment. In this embodiment, the guide fan 2 is configured as a circular cover-shaped profile, arranged at the center of the main unit 5, and a connecting rod 4 extends downward from the center of the circle. The hot air blower 1 is connected to the pivot structure 41 at the connecting rod 4, so that the hot air blower 1 can change the position of the air outlet 113 around the pivot structure 41. When the hot air blower 1 is placed in the horizontal direction of the main unit 5, the hot air can be blown directly onto the dried items to a greater extent. If the pivot structure 41 is controlled to automatically rotate in one direction, a more uniform drying effect can be obtained. If the pivot structure 41 is controlled to rotate back and forth within a certain angle range, the drying effect can be enhanced in key areas. The air duct member 21 in this embodiment includes a circular base plate and an inner partition extending on the base plate to form an inner circle channel and an outer partition forming an outer circle channel with the inner partition. The inner circle channel is configured as an air inlet groove 214, the outer circle channel is configured as an air outlet groove 215, and the second fan 22 is assembled at the center position of the base plate. Through the drainage effect of the second fan 22, the guide fan 2 takes in air from the center and discharges air from the periphery. Specifically, the circulating air supply channel of this embodiment is as follows: the hot air starting from the single-sided hot air blower 1 at the bottom is blown upward, flows through the dried object from bottom to top, and reaches the guide fan 2. The guide fan 2 introduces the hot air from its central air inlet slot 214 and blows it downward from the air outlet slot 215 of the outer ring on the opposite side, flowing through the dried object on the opposite side from top to bottom. The residual hot air and the surrounding air enter the hot air blower 1 from the air inlet 114 on both sides of the hot air blower 1, are heated again and blown out. The hot air blower 1 circulates in the above manner and forms an internal-external circulating air supply channel in the drying area 3.

[0033] Furthermore, the connecting rod 4 can be configured as a length-adjustable structure for adjusting the vertical coverage of the drying area 3. One possible implementation is that the connecting rod 4 includes at least one telescopic segment, and the length of the connecting rod 4 is controlled by controlling the retraction or expansion of the telescopic segment. The telescopic segment can be retracted or expanded manually or electrically controlled.

[0034] In summary, the present application provides a self-circulating drying system, comprising a hot air blower, a guide fan, and a drying area formed by the hot air blower and the guide fan being spaced apart, wherein the hot air blower and the guide fan mutually guide air to form a circulating air supply channel in the drying area. The self-circulating drying system of the present application utilizes the hot air blower and the guide fan to form an open drying area, which facilitates the use of the drying function of the electric clothes drying machine. That is, it is easy to activate and does not require the addition, reduction, or adjustment of accessories of the electric clothes drying machine, while also improving the drying effect to a certain extent.

[0035] In another possible embodiment, the present application provides a control method for an electric clothes drying machine based on the aforementioned self-circulating drying system and the electric clothes drying machine equipped with the self-circulating drying system, specifically comprising the following steps: Obtain the current load of the drying component 6 to confirm the status of the drying area 3; Determine the drying mode for the current drying zone 3 based on the selected priority; Adjust the working posture of the self-circulating drying system according to the current drying mode; Start the self-circulating drying system to execute the current drying mode.

[0036] Regarding the method for confirming the status of the drying area 3, the drying assembly 6 of this embodiment can be equipped with at least one of a weight detection module, an ultrasonic detection module, an illumination detection module, an infrared detection module, and a humidity detection module to confirm the status of the open drying area 3 through multiple different detection dimensions. The status of the drying area 3 referred to in this embodiment can be understood as the range and density of the dried clothes hanging on the drying assembly 6, as well as the overall humidity of the dried clothes themselves, so that the drying control module can configure a reasonable drying mode according to the status of the drying area 3. For example: a. Detect the extent of the dried items on the drying assembly 6 using at least one of an ultrasonic detection module, an illumination detection module, and an infrared detection module. Once the three-dimensional boundaries of the dried items are determined, the boundaries of the drying zone 3 are further determined based on the extent of the circulating air supply channel formed by the self-circulating drying system. Ideally, the dried items should be completely within the drying zone 3. However, if localized drying of a specific area is desired, the boundaries of the drying zone 3 can be adjusted by adjusting the spacing and air outlet orientation of the hot air blower 1 and the guide air blower 2. In this case, the boundaries of the dried items will not completely fall within the drying zone 3.

[0037] b. Detect the load density of the dried items on the drying assembly 6 using at least one of an ultrasonic detection module, an illumination detection module, and an infrared detection module. This provides reference parameters for calculating the drying time, configuring the wind speed and / or heating power of the hot air blower 1, and the wind speed of the diverter fan 2. To further improve the accuracy of load density detection, at least one of the ultrasonic detection module, the illumination detection module, and the infrared detection module can be installed on the connecting rod 4. Connecting rod 4 can be positioned closer to the dried items than the drying assembly 6, or the connecting rod 4 can be positioned so that the receptive field of the aforementioned sensor covers the detection area not reached by the sensor on the drying assembly 6.

[0038] c. Detect the humidity of the dried items using at least one of an ultrasonic detection module, an infrared detection module, and a humidity detection module, providing reference parameters for calculating the drying time, configuring the wind speed and / or heating power of the hot air blower 1, and the wind speed of the guide fan 2. To further improve the accuracy of detecting the humidity of the dried items, particularly the surface humidity of the dried items, as previously mentioned, at least one of an ultrasonic detection module, an illumination detection module, and an infrared detection module can be configured on the connecting rod 4.

[0039] d. Estimate the dry weight of the items using at least one of a weight detection module, an ultrasonic detection module, an infrared detection module, and a humidity detection module. This provides reference parameters for calculating the drying time, configuring the wind speed and / or heating power of hot air blower 1, and the wind speed of guide fan 2. To further improve the accuracy of estimating the dry weight of the items, an ultrasonic detection module and / or an infrared detection module may be installed on connecting rod 4.

[0040] Regarding the drying mode, based on the configuration of the electric clothes drying machine of the present application, the drying mode that can be provided by the present application is a combination of at least part of the following states: a. Spacing between the hot air blower 1 and the guide fan 2: In this embodiment, the hot air blower 1 is arranged below the guide fan 2. When the hot air blower 1 and the guide fan 2 are connected by a retractable connecting rod 4, the spacing between the hot air blower 1 and the guide fan 2 is controlled by the total length of the connecting rod 4. The larger the spacing between the hot air blower 1 and the guide fan 2, the larger the drying area 3, and the more and larger the dried objects that can be covered. However, the heat loss incurred by the hot air during a single cycle is greater, and the air flow concentration is worse, and higher energy is required to maintain a certain wind speed or heating temperature. Conversely, shortening the spacing between the hot air blower 1 and the guide fan 2 is conducive to improving the thermal energy utilization rate of the hot air, and can enhance drying in key areas. b. Wind speed and / or heating power of the hot air blower 1: The wind speed that the hot air blower 1 can generate is related to the fan used. The speed of a specific fan model has an upper limit. Generally speaking, the higher the performance of the fan, the higher the cost of use. The hot air temperature that the hot air blower 1 can generate is related to the heating unit used. The heating power of a specific heating unit model has an upper limit. Similarly, the higher the performance of the heating unit, the higher the cost of use. In addition, with regard to clothing, clothes made of different fabrics have different temperature tolerances. The combination of wind speed and temperature can dry clothes without damaging them, and even achieve wrinkle removal and sterilization effects. c. The speed of the guide fan 2: The speed of the guide fan 2 affects the efficiency of the hot air circulation. After the hot air blown by the hot air blower 1 passes through the clothes being dried, it is not promptly guided by the guide fan 2. The hot air energy will be freely dissipated near the main unit 5. This is not only a waste of energy, but also has an adverse effect on the main unit 5. The high temperature may affect the operation of the motor on the main unit 5 or the sensitivity of various sensors on the main unit 5. d. The direction of the air inlet 114, air outlet 113 of the hot air blower 1 and / or the air inlet slot 214, air outlet slot 215 of the guide fan 2: The direction of the inlet and outlet of the hot air blower 1 and the guide fan 2 can affect the specific implementation of the circulating air supply channel, such as Figure 1 and Figure 3 The embodiment shown forms a double circulation air supply channel from inside to outside, such as Figure 5 The embodiment shown forms a one-way circulating air supply channel from one side to the other side. Those skilled in the art can further improve the structure of the guide fan 2 so that the circulating air supply channel can be switched in several ways. e. The swing range and / or swing speed of the hot air blower 1: Figure 5 As shown, the hot air blower 1 in this embodiment can rotate around the pivot structure 41. When a suitable driving module is configured on the pivot structure 41, the swing range and swing speed of the hot air blower 1 can be controlled to facilitate the function of drying key areas, thereby saving drying energy and drying time.

[0041] The priorities described in this application are primarily based on the drying target of the items being dried, and may include: time priority—completing the drying process in the shortest possible time, within a specified time period, or before a specified time point; fabric priority—configuring the drying mode parameters based on the selected fabric's tolerance; power priority—configuring the drying mode parameters based on the performance limits of the hot air blower 1 and the guide fan 2; and local priority—configuring the drying mode parameters based on the status of the designated key drying area 3. As user needs diversify, other types of priorities may be set, preferably forming a drying mode based on a combination of the aforementioned controllable states of the clothes drying machine.

[0042] by Figure 5 Taking the illustrated embodiment as an example, the control method of the electric clothes drying machine of the present application is further described.

[0043] The self-circulating drying system of the present application can be controlled by a unified control module of the host 5, or can be configured with an independent control module. The control module is configured with a storage module that receives data collected by various sensors and can use the data in the storage module to calculate and configure control parameters for the self-circulating drying system.

[0044] refer to Figure 6In one possible implementation, after receiving the drying instruction, the control module confirms the boundary of the drying area 3 and the humidity state of the dried items according to the current load of the drying component 6, and configures a reasonable drying mode and adjusts the relevant execution parameters according to the selected priority. Then, the drying instruction is executed, and the working postures of the hot air blower 1 and the guide fan 2 are adjusted first to facilitate the solidification of the drying area 3 and the circulating air supply channel. Those skilled in the art can further understand that the drying area 3 mentioned in this application refers to an area that can reach the wind speed and temperature configured for the current drying mode, and this area also belongs to the core area of the circulating air supply channel.

[0045] Optionally, a drive assembly (not shown) is disposed between the connecting rod 4 and the hot air blower 1, respectively driving the extension and retraction of the connecting rod 4 and the rotation of the hot air blower 1 about the distal end of the connecting rod 4. The connecting rod 4 and the pivot structure 41 serve as the active structure of the self-circulating drying system. The extension of the connecting rod 4 determines the vertical extent of the drying zone 3, while the fixed angle of the hot air blower 1 determines the lateral extent of the drying zone 3. When the longitudinal axis of the hot air blower 1 is horizontal, the drying zone 3 substantially does not extend beyond the upward projection of the distal end of the hot air blower 1. When the longitudinal axis of the hot air blower 1 is vertical, the drying zone 3 may extend to a limited extent beyond the downward projection of the main unit 5. When the longitudinal axis of the hot air blower 1 is tilted upward relative to the horizontal plane, the drying zone 3 contracts toward the center of the connecting rod 4. Conversely, when the longitudinal axis of the hot air blower 1 is tilted downward relative to the horizontal plane, the drying zone 3 expands outward toward the center of the connecting rod 4.

[0046] The working posture of the guide fan 2 can be adjusted in the following ways: in one possible implementation method, two or more second fans 22 with adjustable positions or angles can be configured, and the hot air diversion direction or diversion amount can be adjusted by adjusting at least one of the speed, direction, shaft position and shaft angle of each second fan 22 to match the wind direction of the hot air blower 1 to form a circulating air supply channel that conforms to the current drying mode; another implementation method, as described above, is to configure movable swing blades and / or air duct parts 21 to adjust the hot air diversion direction or diversion amount by changing the air duct inside the guide fan 2.

[0047] Furthermore, after adjusting the working postures of the hot air blower 1 and the guide fan 2 in the above manner, the hot air blower 1 and the guide fan 2 are started, and the drying timer is started. Optionally, a basic drying time can be set. After the drying timer is started, the basic drying time is counted down, and the countdown value is the remaining timer. When time is prioritized, the predicted drying time can also be used as the current drying time. After the drying timer is started, the current drying time is counted down, and the countdown value is the remaining timer. When other priorities are selected, the timing can be performed according to the above-mentioned setting of the basic drying time.

[0048] The remaining drying time is periodically predicted based on the current state of the clothes to be dried, and the current state of the clothes to be dried is detected using the various sensors that have been configured as described above. For example, the humidity and / or temperature of the surface of the clothes to be dried, the current humidity and / or temperature of the periphery of the clothes to be dried, the current humidity and / or temperature of the air reaching the guide fan 2, the weather data of the day, and / or the weather forecast data of the day are obtained. The data obtained by at least one of the above methods are used to evaluate the current dryness of the clothes to be dried and the time required for subsequent drying, thereby providing a basis for subsequent adjustment of the drying mode or the execution parameters of the current drying mode.

[0049] When the predicted remaining drying time is less than the remaining timed time of the current drying time, based on the principle of economy, the remaining timed time should be replaced with the remaining drying time until the next prediction period arrives.

[0050] When the predicted remaining drying time is greater than the remaining timing of the current drying time, it is necessary to first confirm whether to adjust the current drying mode based on the current priority. In one possible implementation, the current priority is "fabric priority" or "local priority", and the current drying mode or the execution parameters of the current drying mode are not adjusted until the next prediction cycle is reached; when the priority is "time priority" or "power priority", the current drying mode or the execution parameters of the current drying mode are adjusted so that the remaining drying time predicted in the next prediction cycle is not greater than the remaining timing of the current drying time. This can be understood as accelerating the drying process by adjusting the drying mode or the execution parameters of the current drying mode, in order to achieve the drying effect when the remaining timing is 0. If the drying process is set to switch between two or more priorities, or the user forcibly switches the priority, the remaining drying time can be predicted after switching the priority and before entering the next prediction cycle to confirm whether the remaining timing needs to be replaced.

[0051] When the predicted remaining drying time is equal to the remaining timed time of the current drying time, the current drying mode is not adjusted until the next prediction cycle is reached.

[0052] When the remaining timer for the current drying time counts down to zero, the hot air blower 1 and, preferably, the guide air blower 2 are turned off to terminate the current drying mode. The drive assembly then controls the active structure to reset the self-circulating drying system. If the self-circulating drying system is initially stored close to the main unit 5, "resetting" means returning the self-circulating drying system to its storage position within the main unit 5. If the self-circulating drying system is initially suspended at a designated position below the main unit 5, "resetting" means returning the self-circulating drying system to its initial suspended position. Resetting the self-circulating drying system after the drying command is executed serves to both notify the user that the drying process has ended and facilitate the user's removal of the dried clothing hung on the drying assembly 6.
