Description

Technical Field

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

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

[0003] However, when existing drying devices are used to dry objects, users often have to open the drying bag at irregular intervals and touch the objects to judge their dryness. This manual operation needs to be repeated many times, which is time-consuming and labor-intensive. At the same time, opening the drying bag will cause the drying airflow to be lost, which will affect the drying efficiency of the drying device. Utility Model Content

[0004] Therefore, it is necessary to provide a drying device that addresses the problems of time-consuming and labor-intensive use, which affects drying efficiency.

[0005] This application discloses a drying apparatus, comprising:

[0006] A drying bag having a drying chamber for accommodating objects to be dried, the drying bag having an air inlet and an air outlet, both of which are connected to the drying chamber;

[0007] A dryer, wherein the dryer is connected to the drying bag, the air outlet of the dryer is connected to the air inlet, and the drying airflow output by the dryer flows from the air inlet through the drying chamber to the air outlet and exits; and

[0008] The sensor defines the airflow path from the dryer to the object to be dried as the first path, and the airflow path after passing the object to be dried to the exhaust port as the second path, and the sensor is disposed on the second path;

[0009] The sensor is a temperature sensor or a humidity sensor.

[0010] In this drying device, the dryer is mounted on a drying bag, and the dryer's outlet is connected to the drying bag's inlet. The drying airflow blowing from the outlet flows sequentially through the inlet and the drying chamber before finally exiting from the exhaust port. The airflow path from the dryer to the object to be dried is defined as the first path, and the airflow path after passing the object to be dried and flowing to the exhaust port is defined as the second path. A sensor is mounted on the second path. During use, the object to be dried is placed in the drying chamber, and then the dryer is turned on. The dryer generates a drying airflow that blows into the drying chamber, creating a heat-drying effect on the object. The moisture in the object is heated and evaporated into water vapor, thus... The process achieves the effect of drying the object to be dried. Then, a drying airflow mixed with water vapor evaporated from the object forms a humid airflow. This humid airflow flows along the drying chamber to the exhaust vent and is eventually discharged. During this process, sensors configured as temperature or humidity sensors can detect the temperature or humidity of the humid airflow discharged from the exhaust vent in real time. This allows for automatic and accurate determination of the drying degree of the object, eliminating the need for the user to periodically open the drying bag and frequently touch the object to check for dryness. This effectively saves the user's time and effort while preventing the loss of drying airflow and ensuring the drying efficiency of the device.

[0011] The technical solution of this application will be further described below:

[0012] In one embodiment, the sensor is installed at the exhaust port of the drying bag.

[0013] In one embodiment, the sensor is disposed in the dryer, extends into the drying bag, and is located at the end of the air outlet away from the object to be dried.

[0014] In one embodiment, the sensor includes a sensing head that defines the drying chamber as having a dripping area along the direction of gravity when the object to be dried is suspended.

[0015] The sensor head is disposed in the dripping area, and the sensor head is provided with a shield to prevent dripping water from entering the sensor head; or, the projection surface of the dripping area along the direction of gravity is defined as a first plane, and the sensing end face of the sensor head is defined as a second plane, wherein the angle α between the first plane and the second plane is greater than or equal to 90° and less than or equal to 180°.

[0016] Alternatively, the sensor may be located outside the dripping area.

[0017] In one embodiment, the sensing head has a sensing hole, through which the sensor detects the temperature or humidity of the airflow;

[0018] The sensor has a dustproof component at the sensing head, which is located on the outside of the sensing hole to prevent debris from entering the sensing hole.

[0019] In one embodiment, the dryer is provided with a mounting hole facing the drying bag and located at the end of the air outlet away from the object to be dried. The sensor also includes a sensing body, with a sensing head disposed at one end of the sensing body. The sensing body is disposed inside the mounting hole, and the sensing head protrudes from the mounting hole.

[0020] The sensor extends into the drying bag through the air inlet of the drying bag.

[0021] In one embodiment, the drying bag includes a bag head, a bag body, and a bag tail that are connected in sequence and form the drying chamber, the air inlet is located at the bag head, the bag body, or the bag tail, and the air outlet is located at the bag tail.

[0022] The bag head can accommodate a shelf, and the object to be dried can be placed on the shelf. The volume of the main body is greater than the volume of the bag head.

[0023] In one embodiment, the direction from the bag head to the main body is defined as a first direction, and at least one inner wall of the main body is inclined outward from the drying chamber along the first direction.

[0024] In one embodiment, the air inlet is located on the side of the main body near the tail of the bag, or the air inlet is located at the tail of the bag, and the object to be dried is in the process of being suspended for drying, with the air inlet located below the suspended object to be dried;

[0025] The exhaust vent is located at the tail of the bag, away from the main body. When the object to be dried is in the hanging drying process, the exhaust vent is located below the air inlet.

[0026] In one embodiment, the dryer is provided with a first air outlet and a second air outlet, and both the first air outlet and the second air outlet are provided with air guides, which can guide the air outlet direction.

[0027] The first airflow, guided by the air guide of the first air outlet, is blown to one side of the inner wall of the drying chamber. The second airflow, guided by the air guide of the second air outlet, is blown to the other side of the inner wall of the drying chamber. After being blocked and bounced by the corresponding inner walls, the first airflow and the second airflow can intersect and generate turbulence. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0041] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] See Figure 1 This application illustrates a drying device 100 in one embodiment, which is specifically a portable drying device 100, mainly used for drying objects to be dried.

[0043] For example, the object to be dried can refer to clothing, electrical appliances, pets, etc., depending on the actual needs. For ease of understanding of the technical solution, the object to be dried in this application specifically refers to clothing.

[0044] It should be noted that, for ease of carrying and use, the drying device 100 has two structural forms: unfolded and folded. When in the unfolded form, it can be used to dry objects normally; when in the folded form, it is small in size and occupies little space, thus making it convenient to store and carry.

[0045] Please continue reading. Figure 1 For example, the drying device 100 includes a drying bag 10, a dryer 20, and a sensor 30. The drying bag 10 is the main structure of the drying device 100, which serves to provide the space required for drying the object and to act as a mounting carrier for the dryer 20 and the sensor 30.

[0046] The drying bag 10 is made of a foldable, breathable material, specifically fabric, allowing for easy switching between folded and unfolded structural forms. It is lightweight yet durable. The interior of the drying bag 10 features a hollow design to create a cavity for holding the items to be dried.

[0047] In order to facilitate the insertion or removal of the object to be dried into the cavity, the drying bag 10 has an inlet and outlet, and the inlet and outlet are equipped with zippers, buckles and other opening and closing structures.

[0048] Please continue reading. Figure 1 and Figure 2 The drying bag 10 has a drying chamber 10a that can accommodate the object to be dried. The drying bag 10 is provided with an air inlet 17 and an air outlet 12, both of which are connected to the drying chamber 10a. It can be understood that the drying chamber 10a is a part of the cavity inside the drying bag 10, or it can be the entire cavity, which can be flexibly selected according to actual needs.

[0049] The dryer 20 is connected to the drying bag 10, and the air outlet 23 of the dryer 20 is connected to the air inlet 17 of the drying bag 10.

[0050] It should be noted that in this embodiment, the drying airflow output by the dryer 20 flows from the air inlet 17 through the drying chamber 10a to the exhaust outlet 12. This effect can be achieved by arranging airflow channels to guide the airflow, or by utilizing the characteristics of the airflow output by the dryer 20 and adjusting the shape of the drying bag 10. In this application, the drying bag 10 is set vertically, and the air inlet 17 is positioned slightly below it. The object to be dried is placed in the drying chamber 10a at a position no lower than the air inlet 17, while the exhaust outlet 12 is positioned below the air inlet 17. Thus, the hot air blown in by the dryer 20 will flow upwards, drying the object. Then, the drying airflow, carrying moisture, flows downwards from the exhaust outlet 12 with the help of the guiding effect of the inner wall of the drying chamber 10a and gravity, thereby forming a circulating airflow within the drying chamber 10a.

[0051] The airflow path from the dryer 20 to the object to be dried is defined as the first path, and the airflow path after passing the object to be dried and flowing to the exhaust port 12 is defined as the second path. The sensor 30 is located on the second path. More specifically, the sensor 30 is a temperature sensor or a humidity sensor, used to detect the temperature and / or humidity of the airflow flowing through the drying chamber in order to provide feedback on the drying degree.

[0052] In one embodiment, the dryer 20 and sensor 30 can be an integral part of the drying bag 10, or they can be detachably assembled. For example, in this application, the dryer 20 and sensor 30 are assembled with the drying bag 10 in a detachable structure so that the dryer 20 and sensor 30 can be periodically disassembled to clean the drying bag 10.

[0053] Furthermore, the sensor 30 is electrically connected to the dryer 20. The dryer 20 can flexibly adjust the drying airflow output to the drying chamber 10a according to the temperature or humidity value detected in real time by the sensor 30, taking into account both the drying effect and energy consumption control of the drying device 100.

[0054] Optionally, the sensor 30 can be installed at the exhaust port 12 of the drying bag 10 (e.g., Figure 1 (As shown), it can also be installed on the dryer 20, with the sensor 30 extending into the drying bag 10 (as shown). Figure 3 and Figure 4 As shown), for example, the detection probe of sensor 30 extends into the inside of the drying bag 10. This allows for the provision of drying devices 100 with different product forms to meet the preferences and needs of different consumers.

[0055] When the sensor 30 is installed on the drying bag 10, the installation method can be, but is not limited to, hole-embedding, adhesive installation, snap-fit ​​installation, magnetic installation, installation via bracket, etc.

[0056] In one embodiment, the sensor 30 is disposed in the dryer 20 and extends into the drying bag 10, and is located at the end of the air outlet 23 away from the object to be dried.

[0057] Furthermore, the sensor 30 is positioned between the air outlet 23 and the exhaust outlet 12 of the dryer 20. In this way, the sensor 30 can detect the temperature and / or humidity values ​​of the hot and humid airflow discharged from the exhaust outlet 12, while avoiding the direct influence of the dry airflow blown out from the air outlet 23.

[0058] When the sensor 30 is installed on the dryer 20, in one embodiment the dryer 20 has a mounting hole 21, and the sensor 30 is installed in the mounting hole 21. The installation method is simple, and the sensor 30 is housed in the mounting hole 21, which prevents the sensor 30 from protruding from the surface of the dryer 20, thereby reducing space occupation and facilitating the thin design of the drying device 100.

[0059] In summary, implementing the technical solution of this embodiment will yield the following beneficial effects:

[0060] In the drying apparatus 100 of this application embodiment, the dryer 20 is installed on the drying bag 10, and the air outlet 23 of the dryer 20 is connected to the air inlet 17. The drying airflow blown out from the air outlet 23 flows through the air inlet 17 and the drying chamber 10a in sequence and can finally be discharged from the exhaust port 12. The path of the drying airflow before and after the exhaust port 12 is defined as the first path. Then, the sensor 30 is installed on the first path. When in use, the object to be dried is placed in the drying chamber 10a.

[0061] Next, the dryer 20 is turned on, and the dryer 20 generates a drying airflow and blows it into the drying chamber 10a to form a hot drying effect on the object to be dried. The moisture in the object to be dried is heated and evaporated into water vapor, thereby achieving the effect of drying the object to be dried. At this time, the hot air mixes with water vapor to generate a humid and hot airflow. Then, the humid and hot airflow mixed with water vapor flows along the drying chamber 10a to the exhaust port 12, and is finally discharged from the exhaust port 12.

[0062] During this process, sensor 30 can detect the temperature or humidity of the hot and humid airflow discharged from exhaust vent 12 in real time, thereby automatically and accurately determining the degree of drying of the object to be dried. Specifically, if the temperature of the discharged airflow increases, it indicates that the humidity of the object to be dried is decreasing; conversely, if the humidity of the discharged airflow decreases, it indicates that the humidity of the object to be dried is decreasing. This eliminates the need for the user to periodically open the drying bag 10 and frequently touch the object to determine if it is dry, effectively saving the user's time and effort while preventing the loss of drying airflow (i.e., heat), ensuring the drying efficiency of the drying device 100.

[0063] Optionally, the sensor 30 in this application may be any one of a temperature sensor, a humidity sensor, and a temperature and humidity sensor.

[0064] For example, when sensor 30 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.

[0065] More specifically, the temperature sensor has a detection accuracy of less than 0.5 degrees.

[0066] Alternatively, when sensor 30 is a humidity sensor, the humidity sensor directly detects the moisture content in the hot and humid airflow discharged from the exhaust port 12. 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.

[0067] It should be noted that the sensor 30 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, and the temperature of the output hot air can be controlled according to the detection data of the sensor 30.

[0068] In this application, the dryer 20 can be any mature type of drying equipment in the prior art, such as a drying equipment with heating element as heating wire, PTC or at least one of these, as long as it can heat the air to generate hot air for drying the object to be dried. The specific type can be flexibly selected according to actual needs.

[0069] Based on any of the above embodiments, the sensor 30 includes a sensing head that defines a dripping area in the drying chamber 10a along the direction of gravity when the object to be dried is suspended. It is easy to understand that under the action of gravity, the moisture in the object to be dried will gather towards the lower part of the object (when the object to be dried is clothing, the lower part specifically refers to the hem of the clothing) and then form water droplets that drip down.

[0070] The sensor head is positioned in the dripping area and is equipped with a shield to prevent water droplets from entering the sensor head. The shield prevents water droplets from falling onto the sensor head and damaging the sensor 30.

[0071] Alternatively, as an alternative, the projection surface of the dripping area along the direction of gravity can be defined as the first plane, and the sensing end face of the sensor head can be defined as the second plane. The angle α between the first plane and the second plane is greater than or equal to 90° and less than or equal to 180°. Alternatively, the sensor 30 can be positioned outside the dripping area. This effectively prevents water droplets from directly falling onto the sensor 30, protecting its safety.

[0072] Furthermore, the sensing head has a sensing hole, through which the sensor 30 detects the temperature or humidity of the airflow.

[0073] Furthermore, the sensor 30 is equipped with a dust-proof component at the sensing head, which is located outside the sensing hole to prevent debris from entering the sensing hole. This prevents debris from accumulating and adhering to the sensing hole, thus avoiding any impact on the sensor 30's detection capability and accuracy. For example, the debris can be dust, lint, etc.

[0074] In another alternative embodiment, the dryer 20 is provided with a mounting hole 21, which is opened toward the drying bag 10. The mounting hole 21 is located at the end of the air outlet 23 away from the object to be dried. The sensor 30 also includes a sensing body, with a sensing head disposed at one end of the sensing body. The sensing body is disposed in the mounting hole 21, and the sensing head is exposed in the mounting hole 21.

[0075] The sensor 30 extends into the drying bag 10 through the air inlet 17 of the drying bag.

[0076] Thus, by installing the sensor body in the mounting hole 21, the sensor body supports the sensing head, which on the one hand enables the sensor 30 to be installed on the dryer 20, and on the other hand also enables the sensor 30 to be positioned so that the sensing head of the sensor 30 can be inserted into the drying chamber 10a of the drying bag 10 through the air inlet 17 to detect the temperature or humidity of the discharged hot and humid airflow, thereby realizing the automatic judgment of the drying degree of the object to be dried by the drying device 100.

[0077] Based on the above embodiment, the mounting hole 21 is opened towards the drying bag 10 so that the sensor 30 is disposed between the drying bag 10 and the dryer 20. On the one hand, the sensor 30 is arranged between the drying bag 10 and the dryer 20, and the sensor 30 is constrained by both sides of the drying bag 10 and the dryer 20, so that the sensor 30 is installed firmly and reliably and is not easy to loosen or fall off; on the other hand, the sensor 30 is also protected by the drying bag 10 and the dryer 20, improving its resistance to damage.

[0078] Furthermore, the projection of sensor 30 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 30. This creates a concealed installation of sensor 30, making it less visible when the drying device 100 is in use, thus making the appearance of the drying device 100 more streamlined.

[0079] In another embodiment, the dryer 20 also has an opening 22 that communicates with the mounting hole 21, through which a portion of the sensor 30 extends out of the mounting hole 21. This allows the portion of the sensor 30 extending out of the mounting hole 21 to be easily held by the user, facilitating the installation or removal of the sensor 30.

[0080] Furthermore, in this application, the sensor 30 is detachably disposed in the mounting hole 21. This allows the sensor 30 to be periodically removed, facilitating the cleaning of the drying bag 10.

[0081] Depending on the product requirements, the sensor 30 can be installed in the mounting hole 21 in various ways. For example, both the sensor 30 and the wall of the mounting hole 21 are provided with threads, and the sensor 30 is screwed into the mounting hole 21. More specifically, in one embodiment, the sensor 30 is provided with a first threaded portion, and the wall of the mounting hole 21 is provided with a second threaded portion, and the first threaded portion and the second threaded portion are screwed together.

[0082] Alternatively, in another embodiment, one of the sensor 30 and the hole wall of the mounting hole 21 is provided with a locking body, and the other of the sensor 30 and the hole wall of the mounting hole 21 is provided with a locking slot, and the locking body and the locking slot are engaged.

[0083] Alternatively, in another embodiment, a first magnetic element is provided on the sensor 30, and a second magnetic element is provided on the wall of the mounting hole 21, with the first magnetic element and the second magnetic element magnetically connected.

[0084] All of the above installation methods enable convenient and efficient installation and removal of the sensor 30, with low manufacturing costs and strong feasibility.

[0085] In one embodiment, when the drying device 100 is working, the flow path of the drying airflow in the drying chamber 10a forms a drying air duct 11. The drying air duct 11 specifically includes a supply air duct 11a and a return air duct. One end of the supply air duct 11a is connected to the air outlet 23 of the dryer 20 through the air inlet 17, and the other end of the supply air duct 11a is connected to one end of the return air duct. The other end of the return air duct is connected to the exhaust port 12.

[0086] During the drying operation, the dryer 20 generates a drying airflow and blows it into the air supply duct 11a to perform the first drying treatment on the object to be dried in the air supply duct 11a. Then, the drying airflow carrying some moisture turns and flows into the return air duct to perform the second drying treatment on the object to be dried in the return air duct, so as to evaporate and remove more moisture from the object to be dried and obtain a better drying effect. Finally, the hot and humid airflow is discharged from the exhaust port 12 from the drying bag 10, so that the drying bag 10 can maintain a relatively dry environment and ensure the drying effect of the object to be dried.

[0087] Please continue reading. Figure 2 Furthermore, in one embodiment, the return air duct includes a first return air duct 11b and a second return air duct 11c. The supply air duct 11a is arranged between the first return air duct 11b and the second return air duct 11c. The supply air duct 11a is connected to the exhaust port 12 through the first return air duct 11b and the second return air duct 11c. The airflow in the supply air duct 11a is split into a first part of the airflow and a second part of the airflow. The first part of the airflow flows through the first return air duct 11b to the exhaust port 12, and the second part of the airflow flows through the second return air duct 11c to the exhaust port 12. This ensures that the airflow can be discharged from the drying bag 10 more smoothly and quickly, that is, to achieve faster discharge of the humid and hot airflow mixed with water vapor from the drying chamber 10a, thus ensuring the drying effect of the object to be dried.

[0088] Please continue reading. Figure 1 and Figure 2 In addition, in one embodiment, the drying bag 10 includes a bag head 13, a main body 14 and a bag tail 15 connected in sequence and forming a drying chamber 10a, that is, the bag head 13 is connected to one end of the main body 14 and the bag tail 15 is connected to the other end of the main body 14.

[0089] An air inlet 17 is provided at the bag head 13 and / or the main body 14 and / or the bag tail 15, and an air outlet 12 is provided at the bag tail 15, located at the end away from the main body 14.

[0090] The bag head 13 can accommodate a shelf, on which the object to be dried can be placed. Thus, the object to be dried can be installed inside the drying bag 10 via the shelf.

[0091] Furthermore, the volume of the main body 14 is larger than that of the bag head 13. This allows the main body 14 to have a larger cavity to accommodate 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 effects. The smaller volume of the bag head 13 reduces the residence time of the drying airflow within the bag head 13, improving the efficiency of the drying airflow.

[0092] The direction from the bag head 13 to the main body 14 is defined as the first direction, and at least one inner wall of the main body 14 is inclined outward from the drying chamber 10a along the first direction. In this way, the interior of the main body 14 can form an increasing and ample accommodating space, so that the object to be dried can fully unfold and ensure the drying effect.

[0093] Specifically, the first direction is Figure 1 The direction of the middle arrow S.

[0094] The dryer 20 is disposed on the main body 14 and located on the side at the end away from the bag head 13.

[0095] On the one hand, at least one inner wall of the main body 14 is inclined to the outside of the drying chamber 10a, so that the main body 14 has a larger chamber, which can be used to accommodate objects of various sizes to be dried, improving its applicability. At the same time, it is more conducive to the objects to be dried to unfold better, ensuring the drying effect. On the other hand, by rationally arranging the dryer 20, the length of the formed air supply duct 11a and return air duct can be maximized, so that the drying airflow has a longer flow time in the air supply duct 11a and return air duct, thereby more effectively drying the objects to be dried and avoiding the drying airflow being discharged before it can fully dry the objects, resulting in heat waste and affecting the power consumption and economy of the drying device 100.

[0096] When the drying device 100 is in the unfolded state, the bag head 13 is at the top, the bag tail 15 is at the bottom, and the main body 14 is between the bag head 13 and the bag tail 15.

[0097] In order to achieve the installation and positioning of the drying device 100, the internal cavity of the bag head 13 is used to accommodate the shelf. The shelf is equipped with hooks, which can extend from the through hole at the top of the bag head 13 to be hung with external hanging racks, glass or other objects, so as to achieve the hanging and fixing of the drying device 100.

[0098] It should be noted that if the dry air is blown directly from the air outlet 23 of the dryer 20 to the hem of the object to be dried, the hem will dry quickly, while the main body, sleeves, and most other parts of the object will dry very slowly or even be difficult to dry completely. Therefore, this application optimizes the design of the air outlet 23 of the dryer 20. First, the air outlet 23 is designed as two symmetrically arranged outlets. In addition, the rectangular air outlet 23 is tilted so that the drying airflow from the air outlet 23 blows in a fan-shaped path toward the object to be dried and the side wall of the main body 14.

[0099] Among them, a portion of the drying airflow blown directly onto the object to be dried can directly dry the hem of the object to be dried, while another portion of the drying airflow blown onto the side wall of the main body 14 will bounce back and blow onto the main body, sleeves and other parts of the object to be dried due to the obstruction of the side wall. This achieves the effect of drying the entire object (i.e., all parts) simultaneously with the drying airflow, greatly improving the drying efficiency.

[0100] Based on the above embodiments, the inner wall of the bag head 13 is provided with a flow guiding structure 16, which is used to guide the airflow in the supply air duct 11a to turn and flow into the return air duct.

[0101] During operation, the drying airflow generated and blown out by the dryer 20 flows from bottom to top towards the bag head 13 within the air supply duct 11a. Upon reaching the bag head 13, the airflow is quickly redirected to the return air duct on one side by the guiding structure 16, and finally flows from top to bottom towards the exhaust port 12 to discharge the drying bag 10. It is evident that the guiding structure 16 effectively guides the drying airflow back and forth within the drying bag 10, ensuring smooth airflow, avoiding wind noise, and allowing the hot and humid airflow to be discharged from the drying bag 10 more quickly.

[0102] Please continue reading. Figure 1 and Figure 2 More specifically, in one embodiment, the airflow guiding structure 16 includes a first airflow guiding surface 161 and a second airflow guiding surface 162. The first airflow guiding surface 161 and the second airflow guiding surface 162 are arranged side by side along the width direction of the drying bag 10. The first airflow guiding surface 161 is used to guide a first part of the airflow in the supply air duct 11a to turn and flow into the first return air duct 11b, and the second airflow guiding surface 162 is used to guide a second part of the airflow in the supply air duct 11a to turn and flow into the second return air duct 11c.

[0103] With this configuration, on the one hand, the design of the first guide surface 161 and the second guide surface 162 effectively narrows the area of ​​the bag head 13, which helps to improve heat concentration and achieve a better drying effect on the object to be dried; on the other hand, the first part of the airflow and the second part of the airflow in the air supply duct 11a can be more effectively redirected and flowed under the guidance of the first guide surface 161 and the second guide surface 162, which has a good guiding effect on the airflow and ensures the flow efficiency and smoothness of the airflow in the drying bag 10.

[0104] Optionally, the first guide surface 161 and the second guide surface 162 can be any of the following: inclined surface, curved surface, etc., and can be flexibly selected according to actual needs. In this application, both the first guide surface 161 and the second guide surface 162 adopt an inclined surface structure design.

[0105] For example, the inner wall of the main body 14, which is inclined outward toward the drying chamber 10a, is specifically provided with an outward inclination of six degrees. That is, the inner walls on both the left and right sides of the main body 14 have an angle of six degrees with the vertical direction.

[0106] Furthermore, the bag head 13, the main body 14, and the bag tail 15 are connected sequentially along the first direction, and at least one inner wall of the bag tail 15 is inclined towards the inside of the drying chamber 10a along the first direction.

[0107] The exhaust vent 12 is located on the inner wall of the tail portion 15 and / or on the side wall of the tail portion 15 away from the main body 14 along the first direction. This placement of the exhaust vent 12 at the end of the airflow path facilitates more efficient airflow discharge from the exhaust vent 12.

[0108] Furthermore, the bag tail 15 has a first end connected to the main body 14 and a second end away from the main body 14. An exhaust vent 12 is located at the second end, and the width of the bag tail 15 gradually decreases from the first end to the second end. Positioning the exhaust vent 12 at the second end, i.e., at the bottom of the drying bag 10, makes it easier for the hot and humid airflow generated during drying to escape from the drying bag 10, and avoids affecting surrounding people or objects. The tapered structure design of the bag tail 15 helps to further amplify the temperature and humidity changes inside the drying bag 10 in the bag tail 15 area, thereby improving the detection accuracy of the sensor 30.

[0109] 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.

[0110] In one embodiment, the sensor 30 is mounted on the dryer 20, positioned below and outside the air outlet 23 of the dryer 20, and above the exhaust vent 12. This avoids direct interference from the drying airflow from the air outlet 23 of the dryer 20, which could affect the sensor's detection accuracy, while also ensuring the sensor is close to the convergence point of the hot and humid airflow at the exhaust vent 12, thus guaranteeing detection accuracy.

[0111] Furthermore, the air inlet 17 is located on the side of the main body 14 near the tail 15 of the bag, or the air inlet 17 is located at the tail 15 of the bag. During the hanging drying process, the air inlet 17 is located below the hanging object. The exhaust outlet 12 is located on the side of the tail 15 away from the main body 14. During the hanging drying process, the exhaust outlet 12 is located below the air inlet 17. By rationally arranging the air inlet 17, the object to be dried, and the exhaust outlet 12, the smoothness of the drying airflow within the drying chamber 10a is improved, allowing the drying airflow to more effectively carry the moisture generated during drying and discharge it from the exhaust outlet 12, greatly enhancing the drying efficiency of the drying device 100.

[0112] Furthermore, the dryer 20 is equipped with a first air outlet and a second air outlet, both of which are equipped with air guides to direct the airflow. The first airflow, guided by the air guide at the first air outlet, is blown onto one side of the inner wall of the drying chamber 10a, and the second airflow, guided by the air guide at the second air outlet, is blown onto the other side of the drying chamber 10a. After being blocked and bounced by their respective inner walls, the first and second airflows intersect, creating turbulence. This turbulent flow of air disturbs the object to be dried, allowing it to expand more effectively, increasing the contact area with the drying airflow, thereby improving drying efficiency and ensuring the drying effect.

[0113] 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.

[0114] 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.
