[0002] Current vehicle trunks are typically used solely for storage and lack drying functionality. When users need to dry rain gear, wet clothes, sports equipment, pet supplies, etc., while driving, they often rely on stand-alone home dryers or portable drying devices. However, these devices are bulky, take up space, and have high energy consumption and costs. Condenser dryers are complex in structure and consume a lot of power, while hot air dryers have the problem of difficulty in timely removal of moisture, leaving humid and hot air trapped inside the vehicle, which can easily lead to musty smells in the interior and corrosion of metal parts. In addition, placing stand-alone drying devices inside the vehicle can also lead to safety hazards such as messy wiring and insecure mounting, and lacks coordination and energy reuse mechanisms with the vehicle's thermal management system, resulting in low overall efficiency. These pain points are particularly prominent among urban users who frequently drive through water, experience rain and snow, or engage in outdoor activities. Summary of the Invention

[0019] The present invention will now be described in further detail with reference to specific embodiments, so that those skilled in the art can understand it.

[0020] This utility model provides a drying device integrated with a vehicle and placed in the trunk of a car. It includes a drying chamber 1, an air intake pipe 2, and an exhaust pipe 3. The top center of the drying chamber 1 has a downward groove to form an inner cylinder 4, and a cavity 5 is formed between the inner cylinder 4 and the drying chamber 1. The bottom of the drying chamber 1 is provided with an air inlet 6, and the top is provided with an exhaust outlet 7. One end of the air intake pipe 2 is connected to the vehicle's thermal management system, and the other end is connected to the air inlet 6 of the drying chamber 1. One end of the exhaust pipe 3 is connected to the exhaust outlet 7 of the drying chamber 1, and the other end is connected to the vehicle's exhaust system. Using the vehicle-integrated drying device of this embodiment, hot air generated by the vehicle's thermal management system enters the cavity 5 between the drying chamber 1 and the inner cylinder 4 through the intake pipe 2 and the intake port 6. After being evenly distributed circumferentially and axially along the outer wall of the inner cylinder 4 within the cavity 5, the items to be dried in the inner cylinder 4 are dried. The hot air and the items to be dried undergo sufficient heat exchange and mass transfer. The intake port 6 and the exhaust port 7 are connected to the cavity 5, and the hot air is then discharged through the exhaust port 7 and the exhaust pipe 3 and enters the vehicle's exhaust system, achieving closed-loop organized dehumidification. This process ensures the availability of trunk space while also considering drying efficiency and overall vehicle NVH (noise, vibration, and harshness).

[0021] Optionally, it also includes multiple air guide holes 8, which are disposed on the wall of the inner cylinder 4. Exemplarily, in this embodiment of the present invention, after hot air enters the cavity 5, it is directionally infiltrated into the inner cylinder 4 through the array of air guide holes 8, so that the hot airflow enters from multiple points in the inner cylinder 4 and forms an enveloping flow field in the inner cylinder 4, which fully exchanges heat and mass with the items being dried; the air guide holes 8 adopt a small hole array of φ1.5mm~φ3.0mm, which is evenly distributed in 3 to 5 rings along the height direction of the inner cylinder 4 wall, and the hole positions of each ring are staggered to form a kind of "atomized" diffused air curtain, avoiding single-point heat scouring of the fabric or leather surface.

[0022] Optionally, an electronic damper 9 is also included, which is installed on the air intake duct 2. Exemplarily, in this embodiment of the invention, the electronic damper 9 is connected to the vehicle control unit. The electronic damper 9 is used to change the passage cross-section, so that the amount of hot air entering the drying chamber 1 changes according to the control commands of the vehicle control unit. This maintains a near-target temperature and humidity environment under different load and humidity conditions, reducing unnecessary energy consumption. When the temperature is below the set lower limit or the humidity is above the set upper limit, the opening of the electronic damper 9 is increased to increase the amount of hot air; when the temperature reaches the upper limit or the humidity drops to the target range, the opening of the electronic damper 9 is decreased, balancing energy consumption and material durability.

[0023] Optionally, the system also includes a one-way valve 10 and a vacuum pump 11, which are mounted on the exhaust pipe 3, with the vacuum pump 11 installed near the exhaust port 7. Exemplarily, in this embodiment, the one-way valve 10 and the vacuum pump 11 are connected in series on the exhaust pipe 3, with the vacuum pump 11 positioned closer to the exhaust port 7 than the one-way valve 10. The one-way valve 10 is arranged to block external backflow. The one-way valve 10 and the vacuum pump 11 facilitate the rapid discharge of humid air along a predetermined path and suppress odor escape. The vacuum pump 11 is connected to the vehicle control unit.

[0024] Optionally, it also includes a temperature sensor 12 and a humidity sensor 13, which are installed on the wall of the inner cylinder 4; the electronic damper 9, the air pump 11, the temperature sensor 12, and the humidity sensor 13 are all connected to the vehicle control unit. Exemplarily, in this embodiment of the invention, the temperature sensor 12 and the humidity sensor 13 are respectively installed in the upper middle and lower middle positions of the side wall of the inner cylinder 4, maintaining a height difference between them to obtain more representative parameters of the intralayer air mass; the sensor signals are led out to the vehicle control unit through a wiring harness or flexible cable, forming a closed-loop control with the electronic damper 9 and the air pump 11: when the humidity is ≥ the target value (e.g., ≥ 55%RH) and the temperature has not reached the set value (e.g., < 50℃), the opening of the electronic damper 9 is increased and the speed of the air pump is increased; when the temperature reaches the upper limit (e.g., 60℃) or the humidity drops to the target range (e.g., 45%RH~50%RH), the control unit reduces the amount of hot air and the extraction intensity or enters the heat preservation stage.

[0025] Optionally, a cover plate 14 is also included, which is placed at the top of the drying chamber 1, and the air inlet 6 is disposed on the cover plate 14. Exemplarily, in this embodiment of the invention, the cover plate 14 covers the upper opening of the drying chamber 1 and fits snugly against its periphery, thereby suppressing air leakage and heat dissipation in the upper channel. This increases the effective temperature of the inner cylinder 4 under the same heating conditions, reduces heat loss, and lowers operating noise. The cover plate is made of a low thermal conductivity material, which further prevents hot air from escaping.

[0026] Optionally, the cover plate 14 is a pull-out structure, with grooves 15 extending upward from opposite sides of the top of the drying chamber 1, and a baffle 16 extending upward from the other side of the top of the drying chamber 1. Exemplarily, in this embodiment of the invention, the cover plate 14 is a pull-out structure, with grooves 15 extending upward from opposite sides of the top of the drying chamber 1, the grooves 15 containing self-lubricating slide bars or ball bearing slides, and sliders or slide rail seats correspondingly provided on both sides of the cover plate 14 to achieve smooth guidance; the baffle 16 extends upward from the other side of the top of the drying chamber 1, and the baffle 16 cooperates with the end of the cover plate 14 to serve as a stroke termination and closing retention function.

[0027] Optionally, a pull handle 17 is fixedly installed on the cover plate 14. Exemplarily, in this embodiment of the present invention, the pull handle 17 and the cover plate 14 are reliably connected by studs or rivets. The pull handle 17 facilitates the user's application of force to open and close the cover, making the process of picking up and putting down items smoother, thereby reducing interference with the surrounding loading space, and maintaining reliable grip and operational efficiency even with wet hands or wearing gloves.

[0028] The working principle of this utility model: This utility model's vehicle-integrated drying device uses hot air output from the vehicle's thermal management system as a heat source. The hot air enters the annular cavity between the drying chamber and the inner cylinder through the air inlet, spreading circumferentially and then permeating into the inner cylinder through multiple points via air guide holes in the inner cylinder wall, forming a diffused air curtain. This air fully convects and exchanges heat with the items being dried, promoting the migration of moisture from the surface to the main flow area. The humid, hot air at the higher level of the inner cylinder enters the exhaust channel through the exhaust port. Under the action of the air pump and one-way valve, a unidirectional flow and slight negative pressure are formed, continuously removing moisture and suppressing backflow and odor escape. Temperature and humidity sensors are used to coordinate and adjust the intake and exhaust intensity, stabilizing the temperature and humidity inside the cylinder within the target range. The cover plate fits snugly against the periphery, reducing air leakage and heat dissipation, improving thermal efficiency, and reducing noise. This achieves a highly efficient, controllable, and low-disturbance drying process under driving or parking conditions.

[0029] This utility model's vehicle-integrated drying device employs a closed-loop temperature and humidity control system: temperature and humidity sensors collect parameters of the main flow area of ​​the inner cylinder in real time and send them to the vehicle control unit. After comparing these parameters with the target range, the electronic damper and the suction pump are adjusted in a coordinated manner. When "temperature is too low or humidity is too high" is detected, the control unit increases the opening of the electronic damper, increases the speed of the suction pump, and increases the supply of hot air and the ventilation rate, creating a stronger diffused air curtain and a slight negative pressure inside the inner cylinder to quickly remove moisture. When the temperature approaches the upper limit or the humidity drops to the target range, the opening of the electronic damper is gradually reduced and the pump speed is lowered to suppress overheating and overdrying, maintaining stable drying.
