The drying chamber is used to contain an object to be dried and connects the air inlet and the air outlet. It also includes a dryer whose air outlet is connected to the air inlet of the drying bag. Airflow from the dryer flows into the drying chamber from the air inlet, and at least a portion of the airflow passes over the object to be dried and exits the drying chamber from the air outlet. This design firstly avoids excessively concentrated airflow directed towards the lower part of the object to be dried, preventing localized overheating and eliminating potential safety hazards.

Description

Technical Field

[0001] This application relates to the technical field of drying equipment, and in particular to a drying apparatus. Background Technology

[0002] A drying device is a machine that uses heat energy (such as electricity, gas, or coal) to evaporate moisture from materials. A common application is in humid, rainy weather or when space is limited; drying devices can quickly dry clothes, providing users with dry and comfortable garments. Not only do drying devices save time and space compared to traditional air drying, they also effectively sterilize and eliminate mites, protecting the texture and color of the items being dried. With rising living standards and increasing demand for proper care of dried items, drying devices are becoming increasingly popular among consumers.

[0003] Existing drying devices mainly come in two forms: top-outlet and bottom-outlet. The bottom-outlet type places the air outlet at the bottom of the drying device, and the airflow conforms to the principle of air convection, resulting in relatively high drying efficiency. However, because the dryer is placed close to the bottom of the object to be dried, there is a problem of localized overheating during drying, which is less safe. The top-outlet type places the air outlet at the top of the drying device. In this case, it is difficult to effectively deliver hot air to the bottom, resulting in longer drying time, lower efficiency, and increased energy consumption of the drying device. Utility Model Content

[0004] Therefore, it is necessary to provide a drying device that addresses the safety hazards, low drying efficiency, and high energy consumption of traditional technologies.

[0005] This application provides a drying apparatus, which includes:

[0006] A drying bag, the drying bag having a drying chamber, an air inlet, and an air outlet, the drying chamber for containing objects to be dried, the drying chamber connecting the air inlet and the air outlet; and

[0007] The dryer has an air outlet connected to the air inlet of the drying bag. The airflow output by the dryer flows into the drying chamber from the air inlet, and at least a portion of the airflow flows through the object to be dried and flows out of the drying chamber from the air outlet.

[0008] The drying device of this solution is used in applications where objects are to be dried. In use, the object is placed in the drying chamber of the drying bag, and then the dryer is activated. The dryer generates airflow for drying and directs the airflow into the drying chamber through the dryer's outlet and the drying bag's inlet. At least a portion of the airflow flowing through the drying chamber comes into contact with the object, evaporating the moisture into water vapor. Finally, the airflow carrying the water vapor is discharged from the exhaust vent to the outside of the drying bag, thus achieving the drying operation. Compared to traditional technologies, by directing at least a portion of the airflow into the drying chamber through the object, firstly, excessive airflow concentration on the object is avoided, preventing localized overheating and eliminating potential safety hazards. Secondly, the smooth and rapid sequential flow of air through the inlet, drying chamber, and exhaust vent accelerates the removal of water vapor, thereby improving drying efficiency, reducing drying time, and enhancing the working efficiency of the drying device.

[0050] See Figure 1 and Figure 2 This application illustrates a drying apparatus 100 according to an embodiment of the present application, which includes a drying bag 10 and a dryer 20. The drying bag 10 is the main structure of the drying apparatus 100, and is used not only to hold the integrated dryer 20, but also to hold the object to be dried during the drying process.

[0051] In a common usage scenario, the item to be dried is clothing. The wet clothing is placed into the drying chamber 17 inside the drying bag 10, and then the dryer 20 is turned on. Hot air is blown onto the clothing through the dryer 20, which can quickly dry the clothing and solve practical problems such as clothing being difficult to dry naturally and users needing to use their clothes urgently.

[0052] The drying bag 10 can be made of soft material so that it can be folded and stored when not in use, or unfolded when needed.

[0053] For example, the drying bag 10 can be made of any material such as cloth or plastic film, and can be flexibly selected according to actual needs.

[0054] Please continue reading. Figure 1 and Figure 2 Specifically, the drying bag 10 has a drying chamber 17 for containing objects to be dried. In addition, the drying bag 10 also has an air inlet 131 and an air outlet 161, and the drying chamber 17 connects the air inlet 131 and the air outlet 161.

[0055] More specifically, the drying bag 10 includes a bag head 14, a main body 15 and a bag tail 16 connected in sequence. The bag head 14 and / or the main body 15 and / or the bag tail 16 are provided with an air inlet 131 and the bag tail 16 is provided with an air outlet 161.

[0056] The air outlet 21 of the dryer 20 is connected to the air inlet 131 of the drying bag 10. The hot airflow output by the dryer 20 flows into the drying chamber 17 from the air inlet 131, and at least part of the airflow flows through the object to be dried and flows out of the drying chamber 17 from the exhaust port 161.

[0057] The bag head 14, body 15, and tail 16 form a drying chamber 17. Therefore, the drying chamber 17 is simple to form and has ample space, making it suitable for accommodating objects of various sizes to be dried, thus improving its versatility.

[0058] In one embodiment, the volume of the main body 15 corresponding to the drying chamber 17 is larger than the volume of the bag head 14 corresponding to the drying chamber 17. This allows the main body 15 to have a larger cavity to accommodate the objects to be dried, meeting the placement needs of objects of different sizes, and is more conducive to the effective expansion of the objects during the drying process, resulting in better drying effect. The smaller volume design of the bag head 14 reduces the residence time of the drying airflow within the bag head 14, improving the efficiency of the drying airflow.

[0059] Furthermore, the dryer 20 is arranged near the lower end of the drying bag 10 (i.e., near the exhaust port 161). In other words, the drying device 100 of this application adopts a bottom-outlet operation mode, which can better utilize the principle of air convection, making it easier for the airflow to rise and flow to dry the object to be dried, thus helping to improve drying efficiency.

[0060] Specifically, the air inlet 131 can be configured in several ways. For example, the air inlet 131 can be located on the side of the main body 15 near the tail 16 of the bag, or the air inlet 131 can be located at the tail 16 of the bag, so that the air inlet 131 is below the object to be dried in the suspended state. In this way, the hot airflow flowing into the drying chamber 17 from the air inlet 131 can achieve lateral or bottom airflow to the object to be dried, allowing the hot airflow to better pass through the object to be dried, so as to heat-dry the object and obtain a better drying effect.

[0061] The exhaust vent 161 is located on the side of the bag tail 16 away from the main body, so that the exhaust vent 161 is below the air inlet 131. That is, the exhaust vent 161 is arranged at the very bottom of the entire drying bag 10, so that the humid and hot airflow carrying moisture flows downward and more easily reaches the exhaust vent 161, and is then discharged from the exhaust vent 161 from the drying bag 10. The exhaust vent 161 is arranged below the air inlet 131, thereby avoiding interference with the hot airflow delivered by the air inlet 131.

[0062] The direction along the bag head 14 to the main body 15 is defined as the first direction, which is denoted by S1. At least one inner wall of the main body 15 is inclined to the outside of the drying chamber 17 along the first direction.

[0063] In this application, the drying bag 10, when fully unfolded, has a structural shape in the length, width, and thickness directions. For details regarding the length, width, and thickness directions, refer to commercially available suit storage bags. Therefore, the drying bag 10 has two opposite sides in the length direction, two opposite sides in the width direction, and two opposite sides in the thickness direction. In use, the length direction of the drying bag 10 is vertical, while the width and thickness directions are both horizontal.

[0064] For more details, please continue reading. Figure 1 and Figure 2 In one embodiment, the drying bag 10 has a first side 11 and a second side 12 disposed opposite to each other, and a third side 13 connecting the first side 11 and the second side 12. The first side 11 and the second side 12 are opposite sides in the width direction of the drying bag 10, and both the first side 11 and the second side 12 are inclined toward the outside of the drying chamber 17 so that the main body 15 is formed into a trapezoidal structure.

[0065] More specifically, the dryer 20 is installed on the third side 13. The third side 13 is one side of the thickness direction of the drying bag 10. When the drying bag 10 is in use, the third side 13 is usually facing the user, so it is convenient for the user to perform related operations such as start and stop control and air volume adjustment of the dryer 20.

[0066] For example, the dryer 20 can be operated by at least one of the following methods: buttons, touch screen, remote control, voice control, etc.

[0067] Furthermore, the inner wall of the main body 15 that is inclined towards the outside of the drying chamber 17 along the first direction is defined as the first inner wall 151. The air outlet 21 of the dryer 20 is arranged to discharge air along the first direction or in the opposite direction, or the air outlet 21 of the dryer 20 is arranged to discharge air towards the first inner wall 151. It can be understood that the first inner wall 151 is at least one of the first side 11, the second side 12 and the third side 13 corresponding to the inner side of the chamber.

[0068] In addition, the air outlet 21 of the dryer 20 is positioned on the side opposite to the exhaust outlet 161.

[0069] In summary, the technical solution of this embodiment will achieve the following beneficial effects: The drying device 100 of this solution is used in the case of drying objects. When in use, the object to be dried is placed in the drying chamber 17 of the drying bag 10, and then the dryer 20 is started. The dryer 20 generates airflow for drying and flows into the drying chamber 17 through the air outlet 21 of the dryer 20 and the air inlet 131 of the drying bag 10. At least part of the airflow in the drying chamber 17 comes into contact with the object to be dried, thereby evaporating the moisture of the object to be dried into water vapor. Finally, the airflow carrying the water vapor generated by drying is discharged from the exhaust port 161 to the outside of the drying bag 10, so as to realize the drying operation of the object to be dried.

[0070] Based on this, on the one hand, since at least one inner wall of the main body 15 is inclined towards the outside of the drying chamber 17 in the first direction, the internal cavity of the main body 15 has a larger space for the object to be dried to fully expand, increasing the contact area between the object to be dried and the airflow; on the other hand, the air outlet 21 of the dryer 20 is set towards the side away from the exhaust outlet 161, so that part of the airflow flowing into the drying chamber 17 from the air outlet 21 will be directly blown towards the lower part of the object to be dried, so as to form a direct drying effect on the object to be dried; another part of the airflow will be directly blown towards the cavity wall of the drying bag 17 (that is, the first inner wall 151 of the main body 15), and then bounced and blown towards the side of the object to be dried, so as to achieve the drying of the main body of the object to be dried.

[0071] Compared to traditional technologies, by directing at least a portion of the airflow into the drying chamber 17 to flow over the object to be dried, firstly, excessive concentration of airflow towards the object is avoided, thus preventing localized overheating and eliminating potential safety hazards; secondly, the airflow flows smoothly and quickly through the air inlet 131, the drying chamber 17, and the exhaust outlet 161, accelerating the removal of moisture; furthermore, the airflow can simultaneously blow onto the lower part and the main body of the object to be dried, greatly increasing the contact area between the airflow and the object, thereby improving drying efficiency, reducing drying time, and enhancing the working efficiency of the drying device 100.

[0072] Please continue reading. Figure 7 and Figure 8 The air outlet 21 has two outlets, namely a first air outlet 21a and a second air outlet 21b. The first air outlet 21a is inclined towards the first side 11, and the second air outlet 21b is inclined towards the second side 12. With this configuration, a portion of the airflow from the first air outlet 21a and the second air outlet 21b is directly blown onto the entire lower part of the object to be dried, ensuring that the lower part is dried evenly and completely. At the same time, the other portion of the airflow from the first air outlet 21a and the second air outlet 21b is first blown onto the cavity walls of the first side 11 and the second side 12, respectively, and after rebounding, is blown onto the left and right sides of the main body of the object to be dried, respectively, to achieve more even and complete drying of the main body of the object, thereby improving the drying efficiency of the drying device 100.

[0073] It should also be noted that the bottom blowing plus left and right side blowing scheme implemented in this solution for the object to be dried can also create a cross-turbulent flow effect, causing the object to be dried to swing and shake in the drying chamber, so that the airflow can more fully and effectively contact all parts of the object to be dried, thereby obtaining a better drying effect.

[0074] Please continue reading. Figure 7 and Figure 8 In one embodiment, the dryer 20 further includes a housing 22, a heating element (not shown in the figure), and a fan driver (not shown in the figure). An air outlet 21 is opened on the housing 22, that is, both the first air outlet 21a and the second air outlet 21b are opened on the housing 22; the heating element and the fan driver are respectively installed on the housing 22.

[0075] More specifically, the heating element is disposed between the air driver and the first air outlet 21a and the second air outlet 21b, and the housing 22 and the drying bag 10 are detachably connected.

[0076] The housing 22 is used to mount and fix the heating element and the fan driver, and the dryer 20 can be assembled onto the third side 13 of the drying bag 10 through the housing 22.

[0077] The air actuator is used to introduce air to form an airflow, and the heating element is used to heat the airflow to generate a hot airflow, which then flows from the air outlet 21 to the drying chamber 17.

[0078] During operation, the air actuator drives air to flow towards the first air outlet 21a and the second air outlet 21b. During this process, the air flows past the heating element, which heats the air to generate airflow, which then flows into the drying chamber to dry the object. Furthermore, the first air outlet 21a and the second air outlet 21b share a single set of air actuators and heating elements, reducing the number of air actuators and heating elements required. This reduces costs and installation space requirements, enabling a miniaturized design of the dryer 20.

[0079] Optionally, the heating element and the fan driver can be installed in the housing 22 by at least one of the following methods: screw connection, snap-fit ​​connection, adhesive connection, magnetic connection, etc., which can be flexibly selected according to actual needs.

[0080] Please continue reading. Figure 6 and Figure 8 Furthermore, based on the above embodiments, the dryer 20 also includes a controller, a first fan 23, and a second fan 24. A portion of the heating element is located between the first air outlet 21a and the first fan 23, and the remaining portion of the heating element is located between the second air outlet 21b and the second fan 24. The heating element is electrically connected to the controller. During operation, the first fan 23 drives air to flow through the heating element, heating it into a hot airflow. The hot airflow flows into the drying chamber 17 through the first air outlet 21a to dry the object to be dried. Similarly, the second fan 24 drives air to flow through the heating element, heating it into a hot airflow. The hot airflow flows into the drying chamber 17 through the second air outlet 21b to dry the object to be dried. The controller can control the heating amount of the heating element to flexibly adjust the temperature of the hot airflow and achieve a better drying effect.

[0081] Optionally, the heating element can be any one of, but not limited to, heating wire, heating tube, heating plate, PTC heater, etc. The controller can be any one of, but not limited to, circuit board, chip, microcontroller, etc.

[0082] Specifically, the first air outlet 21a is parallel to the fan blade shaft of the first fan 23, and the second air outlet 21b is parallel to the fan blade shaft of the second fan 24, but not coaxial. This avoids the first air outlet 21a and the first fan 23, and the second air outlet 21b and the second fan 24, from stacking in the thickness direction of the dryer 20, which helps to make the dryer 20 thinner, achieving a miniaturized and lightweight design, making it more portable.

[0083] Optionally, the first fan 23 and the second fan 24 can be any type of axial fan, centrifugal fan, etc. The fan volute is designed directly on the housing 22, which helps to reduce the thickness of the dryer 20 and reduce its weight.

[0084] Of course, the fan volute can also be designed as a separate structure from the housing 22, which facilitates the division of production.

[0085] Please see Figure 7 In one embodiment of this application, the dryer 20 further includes an air guide 25, which is disposed at the air outlet 21 of the housing 22. The air guide 25 is used to guide the airflow in a preset direction so that the hot airflow flows from the air outlet 21 to the drying chamber 17 in the preset direction. In this way, with the guidance of the air guide 25, the hot airflow can flow more effectively along the preset direction, so that the hot airflow can better contact the object to be dried and obtain a better drying effect.

[0086] More specifically, the air guide 25 includes an air guide plate and a baffle, which together form at least one air duct. The air duct includes a connected inlet section and an outlet section, with the outlet section arranged in a preset direction. The inlet section of the air duct is used to collect hot airflow, which flows along the air duct and exits from the outlet section in the preset direction. Thus, the inlet section is positioned on the side of the heating element away from the air outlet of the air driver to effectively collect and concentrate the hot airflow generated by the heating element, thereby improving energy utilization. Subsequently, the hot airflow flows from the inlet section to the outlet section and, guided by the outlet section, flows in the preset direction to the object to be dried in the drying chamber 17, thus achieving the drying operation of the object.

[0087] Please continue reading. Figure 2 and Figure 7 Furthermore, based on the above embodiments, the air guide 25 includes a first air guide and a second air guide. The housing 22 is provided with a first air guide corresponding to the first air outlet 21a, and the housing is provided with a second air guide corresponding to the second air outlet 21b. The first air guide is used to guide airflow in a first direction, and the second air guide is used to guide airflow in a second direction. The first direction and the second direction have an angle α.

[0088] The first airflow, guided by the first air guide, flows into the drying chamber 17 and is blown onto one chamber wall. The second airflow, guided by the second air guide, flows into the drying chamber 17 and is blown onto the other chamber wall. After being blocked and bounced by the corresponding chamber walls, the first and second airflows intersect and generate turbulence. This turbulence, caused by the intersection of the first and second airflows, creates a disturbance effect on the object to be dried. The object then oscillates and stretches irregularly, increasing the contact area with the hot airflow and achieving a better drying effect.

[0089] Furthermore, at least two first air guides are provided at the first air outlet 21a, and at least two second air guides are provided at the second air outlet 21b. Air guide grooves are formed between adjacent first air guides and adjacent second air guides. When the generated airflow passes through the first air outlet 21a and the second air outlet 21b, it is guided by the air guide grooves and flows directly and smoothly into the drying chamber along the grooves. This achieves uniform airflow distribution, allowing some airflow to directly blow onto the lower part of the object to be dried, while another part blows onto the side wall of the drying chamber and bounces back towards the main body of the object, improving the directionality and effectiveness of the airflow.

[0090] Please continue reading. Figure 8 Furthermore, in another embodiment, the dryer 20 also includes a temperature sensor 26, which is disposed in the housing 22 and electrically connected to the controller. During the drying process, the temperature sensor 26 can detect the temperature value inside the drying chamber in real time, and then calculate the humidity value of the drying chamber through an algorithm, thereby determining the current drying status of the object to be dried, so as to provide feedback signals to the controller to dynamically adjust the working power and start / stop status of the heating element, which helps to control the drying device 100 to adapt to different operating conditions, so as to save energy and reduce consumption.

[0091] It should be noted that the temperature sensor 26 can also be equipped with a humidity monitoring module, which can directly measure the humidity value inside the drying chamber to determine the drying status of the object to be dried.

[0092] In addition, in one embodiment, the dryer 20 also includes a power cord (not shown), to which both the heating element and the fan driver are electrically connected. The power cord is used to connect to an external power supply device to obtain power and to supply power to the heating element. A circumferential groove is provided along the edge of the housing 22, and the power cord is wound and stored in the groove along the circumference of the housing 22.

[0093] Furthermore, the outer wall of the housing 22 is also provided with a fixing buckle (not shown in the figure), which is used to fix the wound-up connecting wire in the take-up groove. In this way, when the drying device 100 is not in operation, the connecting wire is neatly stored, and the fixing buckle can prevent the connecting wire wound and stored in the take-up groove from unraveling.

[0094] For example, the fastener can take any form, such as a snap-fit ​​or a magnetic snap, and can be flexibly selected according to actual needs.

[0095] Please continue reading. Figure 1 , Figure 2 and Figure 4Considering that the drying bag 10 is made of soft material and the dryer 20 is quite heavy, it is difficult to stably install and support the dryer 20. To address this, in one embodiment, the drying device 100 further includes a mounting frame 30. An air inlet 131 is provided on the third side 13, and the mounting frame 30 is installed at the air inlet 131. The housing of the dryer 20 is detachably connected to the mounting frame 30. Therefore, the mounting frame 30 can effectively support and position the dryer 20, while also allowing the dryer 20 to be easily removed from the mounting frame 30 for regular cleaning of the drying bag 10, preventing damage from water contact.

[0096] For example, the mounting frame 30 can be made of any of the following materials: a rigid plastic basket, a metal frame, etc. The mounting frame 30 can be installed in the mounting space by gluing, sewing, etc., and can be flexibly selected according to actual needs.

[0097] Please continue reading. Figure 4 and Figure 7 In one embodiment, one of the housing 22 and the mounting frame 30 is provided with a locking body 31, and the other of the housing 22 and the mounting frame 30 is provided with a fastening position 221. The locking body 31 and the fastening position 221 are detachably engaged. On the one hand, by means of the engagement of the locking body 31 and the fastening position 221, the dryer 20 and the mounting frame 30 can be assembled and fixed quickly and reliably; on the other hand, the dryer 20 can also be quickly disassembled for regular cleaning of the drying bag 10.

[0098] In some other optional embodiments, the housing 22 and the mounting frame 30 can also be detachably assembled by means of adhesive bonding, magnetic connection, screw connection, etc., which can be flexibly selected according to actual needs, and will not be elaborated here.

[0099] During installation, the dryer 20 is directly pushed horizontally into the cavity formed by the mounting frame 30. The mounting frame 30 is provided with a stop part, which abuts against the housing 22 of the dryer 20 to achieve the installation and positioning of the dryer 20.

[0100] The mounting frame 30 has a ring-shaped structure and a Z-shaped cross-section, which helps to improve the structural strength of the mounting frame 30 and ensure the reliability of the mounting frame 30 on the dryer 20. Of course, in other optional embodiments, the cross-section of the mounting frame 30 can also be C-shaped, U-shaped, or other regular or irregular shapes, which can be flexibly selected according to actual needs, and will not be elaborated here.

[0101] Furthermore, based on any of the above embodiments, an airflow is formed within the drying chamber 17 due to the rising of the hot air output from the dryer 20 and its guidance by the inner wall of the drying chamber 17 of the drying bag 10 in this embodiment. For example, the airflow includes a supply airflow 171 and a return airflow. The inlet section of the supply airflow 171 is connected to the outlet 21 of the dryer 20, and the outlet section of the supply airflow 171 is connected to the inlet section of the return airflow. An exhaust port 161 is also provided at the bottom of the drying bag 10, and the exhaust port 161 is connected to the outlet section of the return airflow.

[0102] During the flow of the supply airflow 171, it passes through the object to be dried. The supply airflow 171 contacts the object to be dried and heats and evaporates the moisture contained in the object, turning the moisture into water vapor, thus achieving the first drying of the object. When the return airflow turns back to the exhaust port 161, it passes through the object to be dried a second time, thus achieving the second drying of the object, improving the utilization rate of heat in the airflow and enhancing the drying effect of the object.

[0103] Furthermore, based on the above embodiment, the return airflow includes a first return airflow 172 and a second return airflow 173. The supply airflow 171 is arranged between the first return airflow 172 and the second return airflow 173, and the supply airflow 171 is connected to the exhaust port 161 through the first return airflow 172 and the second return airflow 173. Arranging the first return airflow 172 and the second return airflow 173 on the left and right sides of the supply airflow 171 respectively enables the supply airflow 171 to be divided into the first return airflow 172 and the second return airflow 173, improving the return efficiency of the airflow, and thus allowing the humid and hot airflow carrying water vapor to flow to the exhaust port 161 more quickly and be discharged from the drying bag 10.

[0104] Please continue reading. Figures 1 to 3 Based on any of the above embodiments, the drying device 100 further includes a hanging member 40, and the drying bag 10 includes a bag head portion 14 and a main body portion 15 connected to each other. The cavity of the bag head portion 14 is used to accommodate a shelf, and the hanging member 40 is used to connect the shelf. The cavity of the main body portion 15 is used to accommodate the object to be dried. The cavity of the bag head portion 14 and the cavity of the main body portion 15 communicate and cooperate to form a drying chamber 17.

[0105] By connecting the hanging member 40 to the shelf, the object to be dried can be suspended inside the drying chamber 17. The drying device 100 is then suspended via the hanging member 40, supported by the shelf and the bag head 14. Based on this, the dryer 20 introduces hot airflow into the drying chamber 17, thereby drying the object.

[0106] At least one inner wall of the bag head portion 14 is inclined outward toward the drying chamber 17 in a first direction. This inner wall of the bag head portion 14 is defined as the second inner wall 144. The first inner wall 151 and the second inner wall 144 are smoothly connected. By designing the first inner wall 151 and the second inner wall 144 to be smoothly connected, the airflow can flow more smoothly from the bag head portion 14 to the main body portion 15.

[0107] In one embodiment, the bag head 14 includes a first side and a second side disposed opposite to each other along a second direction of the drying bag 10, the second direction being denoted as S2 (see [reference]). Figure 2 The first side portion has a first inclined surface 141, and the second side portion has a second inclined surface 143. The first inclined surface 141 and the second inclined surface 143 are arranged symmetrically. The main body portion 15 has a first end connected to the bag head portion 16 and a second end away from the bag head portion 16. The width of the main body portion 15 increases gradually from the first end to the second end. It can be understood that the second inner wall 144 is at least one of the first inclined surface 141 and the second inclined surface 143 corresponding to the inner side of the cavity. Specifically, in the embodiment of this application, the drying bag has a uniform wall thickness as an example.

[0108] On the one hand, since the bag head 14 is located at the junction of the supply airflow 171 and the return airflow, the first side of the bag head 14 is provided with a first inclined surface 141 and the second side is provided with a second inclined surface 143. Compared with the traditional square shape of the bag head 14, the internal space of the two corners is reduced, which reduces the volume of the bag head 14 cavity, reduces the heating of useless air in the bag head 14 by the airflow, and improves the airflow utilization efficiency. On the other hand, the first inclined surface 141 and the second inclined surface 143 play a guiding and diverting role for the airflow, so that the airflow can more smoothly turn from the supply airflow 171 (for example, turn 180°) into the first return airflow 172 and the second return airflow 173.

[0109] The width of the main body 15 (i.e., the dimension along the second direction of the drying bag 10) is designed to increase in a direction away from the bag head 14, so that the shape of the cavity inside the main body 15 is adapted to the shape of the object to be dried in an unfolded state, so as to have sufficient space to accommodate the object to be dried, allowing the object to be dried to unfold more fully during the drying process, ensuring that the object to be dried has more full contact with the airflow, thereby improving the drying effect.

[0110] For example, the first side 11 and the second side 12 of the main body 15 are both designed with an angle that slopes outward toward the drying bag 10, and the angle is 6°. Of course, other dimensions of the slope can also be used in other embodiments.

[0111] It should be noted that an increasing trend can mean a continuous increase, or it can mean an initial increase followed by a decrease followed by an increase again, that is, an overall increasing trend.

[0112] Please continue reading. Figure 1 and Figure 2 In one embodiment, the drying bag 10 further includes a bag tail portion 16, which is connected to the main body portion 15 and located at the end away from the bag head portion 14. The cavity of the bag tail portion 16, the cavity of the main body portion 15, and the cavity of the bag head portion 14 together constitute the drying chamber 17. An exhaust port 161 is provided at the end of the bag tail portion 16 away from the main body portion 15. The bag tail portion 16 has a third end connected to the main body portion 15 and a fourth end away from the main body portion 15. The exhaust port 161 is located at the fourth end. The width of the bag tail portion 16 decreases from the third end to the fourth end.

[0113] The exhaust vent 161 is designed at the bottom of the drying bag 10, at the end of the airflow path where the temperature is lowest. This not only concentrates energy more effectively but also facilitates the discharge of hot and humid air. The tapered structure design with decreasing width at the tail of the bag 16 helps to amplify the temperature and humidity changes inside the drying bag 10 in the tail area 16, thereby improving the detection accuracy of the sensor 50.

[0114] It should be noted that a decreasing trend can mean a continuous decreasing trend, or it can mean a decrease followed by an increase followed by a decrease, that is, an overall decreasing trend.

[0115] That is, in this application, the bag head 14, the main body 15, and the bag tail 16 are connected sequentially along a first direction. At least one inner wall of the bag tail 16 is inclined towards the inside of the drying chamber 17 along the first direction. This inner wall of the bag tail 16 is defined as the third inner wall 162, and the third inner wall 162 is smoothly connected to the first inner wall 151. The third inner wall 162, which is inclined towards the inside of the drying chamber 17, can guide the hot and humid airflow (i.e., the airflow carrying water vapor) to the exhaust port 161 so that the hot and humid airflow can be discharged more quickly. The smooth transition between the third inner wall 162 and the first inner wall 151 can ensure that the hot and humid airflow flows more smoothly from the main body 15 to the bag tail 16, avoiding turbulence caused by poor flow, which would cause wind noise and affect the user experience of the drying device 100.

[0116] The exhaust vent 161 is located on the inner wall of the bag tail portion 16 or on the side wall of the bag tail portion 161 away from the main body portion 151 along the first direction. In this way, the exhaust vent 161 has different configurations to adapt to the needs of different types of drying devices 100, and the exhaust vent 161 can also obtain different opening areas to meet the discharge needs of humid and hot airflows of different flow rates.

[0117] Furthermore, in one embodiment of this application, the air inlet 131 is located on the side of the main body 15 near the tail portion 16 of the bag, or the air inlet 131 is located at the tail portion 16 of the bag. In this way, there is a sufficiently large gap between the air inlet 131 and the head portion 14 of the bag, so that the drying chamber 17 inside the main body 15 has a sufficiently large space to accommodate objects of various sizes to be dried, thereby improving the applicability of the drying device 100.

[0118] In one embodiment, the bag head 14, the main body 15, or the bag tail 16 are all made of a moisture-permeable material, such as fabric. In this way, some of the moisture generated during the drying of the object can directly penetrate the fabric of the drying bag 10 and be discharged to the outside. Combined with the discharge of hot and humid air through the exhaust vent 161, this more effectively increases the moisture discharge rate, creating a drier environment inside the drying bag 10, which is more conducive to faster drying of the object.

[0119] In addition, the drying device 100 also includes a storage section (not shown in the figure), which is connected to the bag head 14, the main body 15, or the bag tail 16. The bag head 14, the main body 15, and the bag tail 16 are all made of a flexible, foldable material. After being folded to a preset state, the bag head 14, the main body 15, and the bag tail 16 can be stored in the storage section. In this way, the drying device 100 can be stored away when not in use, avoiding taking up too much space and facilitating storage and management.

[0120] For example, the storage compartment can be any of the following: storage bag, storage net, storage rope, etc. The choice can be made flexibly according to actual needs, and no specific limitation is made here.

[0121] Please continue reading. Figure 3 Furthermore, based on any of the above embodiments, the hanging member 40 is connected to the end of the bag head 14 away from the main body 15 along a first direction. The bag head 14 can accommodate a shelf, and the shelf and the hanging member 40 are detachably connected. The object to be dried can be placed on the shelf. Therefore, in use, the object to be dried can be installed on the shelf and placed inside the drying bag 10 together with the shelf. At this time, at least the main body 15 can accommodate the clothes to be dried, the bag head 14 can accommodate the shelf, and it can be hung with an external object through the hanging member 40, so that the drying device 100 and the object to be dried can be hung together for use without manual handling.

[0122] Specifically, the hanging component 40 includes a hook body 41, a movable body 42, and a hook ring 43. The hook body 41 and the hook ring 43 are movably connected to the movable body 42. The hook ring 43 is connected to the bag head 14 and located inside the drying chamber 17. The hook ring 43 is detachably connected to the shelf. The hook body 41 is located outside the drying chamber.

[0123] The top of the bag head 14 has a through hole 142. In use, the hook 41 extends from the through hole 142 to the outside of the drying bag 10 for connection to objects such as clotheslines. The hook ring 43 is located inside the bag head 14 for hanging on a shelf. This allows for the hanging of the drying device 100, the object to be dried, and the shelf without manual intervention, making it convenient to use. The movable body 42 allows the hook 41 and hook ring 43 to have relative rotational freedom, making the drying device 100 suitable for various environmental conditions and scenarios.

[0124] For example, the movable body 42 is spherical, specifically a universal ball joint, allowing the hook 41 to move omnidirectionally relative to the hook ring 43 via the movable body 42. This gives the suspension component 40 more degrees of freedom of rotation in multiple directions, improving its performance.

[0125] Please continue reading. Figure 3 Furthermore, in one embodiment, the hook 41 includes a main body 411, a main hook 412, a side hook 413, and a barb 414. The side hook 413 is disposed on one side of the main body 411, and the main hook 412 and the barb 414 are disposed alternately on the other side of the main body 411. The main body 411 is used to load and fix the main hook 412, the side hook 413, and the barb 414, and to give the hook 41 sufficient structural strength. The side hook 413 disposed on one side of the main body 411 faces downward, making it convenient to hang on objects such as doors and windows. The main hook 412 disposed on the other side of the main body 411 makes it convenient to hang on objects such as clotheslines, window frames, and security grilles, giving the drying device 100 different installation capabilities to adapt to different scenarios. The barb 414, which cooperates with the main hook 412, mainly serves to prevent detachment and improve the reliability of the hanging installation.

[0126] Please continue reading. Figure 5 , Figure 7 and Figure 8 Based on any of the above embodiments, the drying device 100 further includes a sensor 50 for detecting temperature or humidity, defining the airflow path from the dryer 20 to the object to be dried as a first path, defining the airflow path after passing the object to be dried and flowing to the exhaust port 161 as a second path, and the sensor 50 is disposed on the second path.

[0127] The sensor 50 is installed on the second path. During use, the object to be dried is placed into the drying chamber 17, and then the dryer 20 is turned on. The dryer 20 generates airflow and blows it into the drying chamber 17 to create a heat drying effect on the object. The moisture in the object is heated and evaporated into water vapor, thereby achieving the effect of drying the object. Then, the airflow mixed with the water vapor generated from the object to be dried forms a humid airflow. The humid airflow flows along the drying chamber 17 to the exhaust port 161 and is finally discharged from the exhaust port 161. During this process, the sensor 50, which is set as a temperature sensor or humidity sensor, can detect the temperature or humidity value of the humid airflow discharged from the exhaust port 161 in real time. This allows for automatic and accurate determination of the degree of drying of the object, eliminating the need for the user to open the drying bag 10 at irregular intervals and frequently touch the object to determine whether it is dry. This effectively saves the user's time and effort, while also preventing airflow loss and ensuring the drying efficiency of the drying device 100.

[0128] Furthermore, at least the detection part of sensor 50 is located in the second path. Sensor 50 is used to detect the temperature or humidity value of the airflow discharged from exhaust vent 161.

[0129] The hot and humid airflow is discharged from the exhaust vent 161. During this process, the sensor 50 can detect the temperature or humidity value of the hot and humid airflow discharged from the exhaust vent 161 in real time, so as to automatically and accurately determine the degree of drying of the object to be dried. This eliminates the need for the user to open the drying bag 10 from time to time and frequently touch the object to be dried to determine whether it is dry. This can effectively save the user's time and energy, and at the same time avoid the loss of airflow (i.e. heat), ensuring the drying efficiency of the drying device 100.

[0130] Sensor 50 is installed on drying bag 10 or dryer 20 to provide different drying device 100 product forms to meet the preferences and needs of different consumers.

[0131] For example, in one embodiment of this application, the sensor 50 is installed in the dryer 20 and extends into the drying bag 10, located at the end of the air outlet 21 away from the object to be dried. In this way, the sensor 50 extends into the drying bag and can contact the hot and humid airflow in the drying chamber 17, thereby enabling the detection of temperature or humidity values; its location away from the air outlet 21 avoids interference from the hot airflow blown out of the air outlet 21, which would affect the detection accuracy.

[0132] In one embodiment, sensor 50 is electrically connected to dryer 20. This allows sensor 50 to transmit the detected humidity or temperature value signal to dryer 20 in real time, enabling dryer 20 to dynamically adjust the heat output and control the airflow rate in the drying chamber 17. This ensures the drying effect of the object to be dried while avoiding energy waste and excessive energy consumption.

[0133] Furthermore, when the dryer 20 also includes a housing 22, the sensor 50 is mounted on the housing 22 and extends into the drying bag 10 through the air inlet 131. The housing 22 reliably mounts and fixes the sensor 50, while the sensor 50 can extend into the drying bag 10 through the air inlet 131 and directly contact the emitted hot and humid airflow, facilitating the detection of humidity or temperature values.

[0134] The sensor 50 is located between the air outlet 21 of the dryer 20 and the air exhaust port 161 of the drying bag 10.

[0135] More specifically, the sensor 50 is positioned below and outside the air outlet 21 of the dryer 20, and above the exhaust vent 161 of the drying bag 10. Positioning the sensor 50 below and outside the air outlet 21 of the dryer 20, and above the exhaust vent 161, avoids direct interference from the airflow blowing from the air outlet 21 of the dryer 20, thus preventing it from affecting its detection accuracy. Simultaneously, it positions the sensor 50 near the convergence point of the hot and humid airflow at the exhaust vent 161, ensuring accurate detection.

[0136] Optionally, the sensor 50 in this application may be any one of a temperature sensor, a humidity sensor, and a temperature and humidity sensor.

[0137] For example, when sensor 50 is a temperature sensor, the temperature sensor detects relative temperature changes rather than absolute temperature values. This can effectively avoid the influence of room temperature and environmental differences on the detection results, making the drying device 100 suitable for various environments.

[0138] More specifically, the temperature sensor has a detection accuracy of less than 0.5 degrees.

[0139] Alternatively, when sensor 50 is a humidity sensor, the humidity sensor directly detects the moisture content in the hot and humid airflow discharged from the exhaust vent 161. When the moisture content reaches or falls below the set value in the humidity sensor, it indicates that the object to be dried has been dried.

[0140] It should be noted that the sensor 50 in this application can be directly electrically connected to the dryer 20, or it can be indirectly electrically connected to the dryer 20 through a controller. In this way, the start and stop of the dryer 20, the blowing intensity, the temperature of the output airflow, etc. can be controlled based on the detection data of the sensor 50.

[0141] When the sensor 50 is installed on the dryer 20, in one embodiment the dryer 20 has a mounting hole 222, and the sensor 50 is installed in the mounting hole 222. The installation method is simple, and the sensor 50 is housed in the mounting hole 222, which prevents the sensor 50 from protruding from the surface of the dryer 20, thereby reducing space occupation and facilitating the thin design of the drying device 100.

[0142] Based on the above embodiment, the mounting hole 222 is opened towards the drying bag 10 so that the sensor 50 is disposed between the drying bag 10 and the dryer 20. On the one hand, the sensor 50 is arranged between the drying bag 10 and the dryer 20, and the sensor 50 is constrained by both sides of the drying bag 10 and the dryer 20, so that the sensor 50 is installed firmly and reliably and is not easy to loosen or fall off; on the other hand, the sensor 50 is also protected by the drying bag 10 and the dryer 20, improving its resistance to damage.

[0143] Furthermore, the projection of sensor 50 in the direction perpendicular to the drying bag 10 overlaps with the projection of dryer 20 in the direction perpendicular to the drying bag 10, with dryer 20 obscuring sensor 50. This creates a concealed installation of sensor 50, making it less visible when the drying device 100 is in use, thus making the appearance of the drying device 100 more streamlined.

[0144] Depending on the product requirements, there are various ways to install the sensor 50 in the mounting hole 222. For example, in one embodiment, the sensor 50 is provided with a first threaded portion, and the wall of the mounting hole 222 is provided with a second threaded portion, with the first threaded portion and the second threaded portion being screwed together.

[0145] Alternatively, in another embodiment, one of the sensor 50 and the hole wall of the mounting hole 222 is provided with a locking body, and the other of the sensor 50 and the hole wall of the mounting hole 222 is provided with a locking slot, and the locking body and the locking slot are engaged.

[0146] Alternatively, in another embodiment, a first magnetic element is provided on the sensor 50, and a second magnetic element is provided on the wall of the mounting hole 222, with the first magnetic element and the second magnetic element being magnetically connected.

[0147] All of the above installation methods enable convenient and efficient installation and removal of the sensor 50, with low manufacturing costs and strong feasibility.

[0148] Furthermore, based on any of the above embodiments, the sensor 50 includes a sensing head that defines a dripping area in the drying chamber 17 along the direction of gravity when the object to be dried is suspended. It is easy to understand that under the influence of gravity, moisture in the object to be dried will converge towards the lower part of the object (specifically, the hem of clothing when the object is clothing), thus forming water droplets that drip down.

[0149] The sensor head 50 is positioned in the dripping area and is equipped with a shield to prevent water droplets from entering the sensor head. This prevents water droplets from falling onto the sensor head and damaging the sensor 30.

[0150] Alternatively, as an alternative to the above embodiment, the sensor head is positioned within the dripping area, with the projection plane of the dripping area along the direction of gravity defined as a first plane, and the sensing end face of the sensor head defined as a second plane. The angle β between the first and second planes is greater than or equal to 90° and less than or equal to 180°. Alternatively, the sensor 50 can be positioned outside the dripping area. With this configuration, water droplets falling under gravity will not directly drip onto the sensor 50, thus protecting the sensor 50.

[0151] Furthermore, the sensor head has a sensing hole through which the sensor detects the temperature or humidity of the airflow. A dust-proof component is provided at the sensor head, positioned outside the sensing hole to prevent debris from entering. This prevents debris from accumulating and adhering to the sensing hole, thus avoiding any impact on the sensor's detection capability and the accuracy of the results. For example, the debris can be dust, lint, etc.

[0152] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0153] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
