Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a defrosting device for automotive air conditioning mixing damper with ultrasonic atomization assistance. Background Technology

[0002] During winter driving, car windows are prone to frost or fogging due to temperature differences and humidity variations between the inside and outside of the vehicle, severely obstructing the driver's vision and posing a significant safety hazard. Traditional defrosting methods mainly rely on the heating function of the car's air conditioning system. This involves directing waste heat from the engine into the air ducts, where a mixing damper adjusts the ratio of hot to cold air before blowing it onto the glass surface, using the hot air to heat the glass and melt the frost.

[0003] However, the engine needs to reach normal operating temperature to provide an effective heat source. Defrosting in cold start conditions can be delayed by more than ten minutes, which cannot meet the immediate driving needs. Secondly, relying solely on hot air defrosting consumes a lot of energy, which not only increases the engine load but also reduces fuel economy due to prolonged operation of the heating system. In addition, high temperature and dry air can easily cause discomfort to the occupants, and repeated thermal shocks may accelerate the aging of glass and sealing materials, resulting in slow response, high energy consumption, and a significant increase in system cost and complexity.

[0004] To improve defrosting efficiency, the industry has attempted to introduce atomized humidification technology, which increases air humidity to accelerate frost melting and reduce the required heat. Early spray devices mostly used high-pressure nozzles or centrifugal atomizers, but these suffered from uneven atomization, easy nozzle clogging, high power consumption, and water residue. Ultrasonic atomization technology, due to its advantages such as producing micron-sized fine water mist, high energy efficiency, and precise control, is gradually entering the automotive field. This technology uses high-frequency vibration to break water molecules into uniform droplets, which can quickly increase local humidity and promote frost dissolution; at the same time, low-temperature atomization avoids damage to the vehicle's interior materials from high-temperature steam. However, existing ultrasonic atomization systems mostly operate independently and are not deeply integrated with the vehicle's air conditioning ducts and mixing dampers, resulting in uneven droplet distribution and insufficient mixing with hot air. This can even lead to water film residue on the glass surface due to localized over-humidification, affecting visibility.

[0005] Therefore, in order to address the above problems, the applicant needs to design a car air conditioning mixed damper defrosting device with ultrasonic atomization assistance to solve the problem. Utility Model Content

[0018] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0019] Please refer to Figure 1 This utility model provides a defrosting device for a car air conditioning mixing damper with ultrasonic atomization assistance, including a base 1, and an ultrasonic atomizer 10 fixedly mounted on the base 1. A connecting pipe 11 is connected above the ultrasonic atomizer 10, and a guide pipe 12 is connected to the air outlet of the connecting pipe 11. A water supply mechanism 2 is fixedly connected to the water inlet of the ultrasonic atomizer 10, and the water supply mechanism 2 supplies clean water to the ultrasonic atomizer 10. The water supply mechanism 2 includes a buffer cylinder 20 fixedly connected to the base 1, and a connecting pipe 22 is fixedly connected to the buffer cylinder 20. A pressure pump 23 is fixedly connected to the water outlet of the connecting pipe 22, and an extension pipe is fixedly connected to the water outlet of the pressure pump 23. 24. The outlet of the extension pipe 24 is fixedly connected to a water supply pipe 25, and the water supply pipe 25 is fixedly connected to the inlet of the ultrasonic atomizer 10. It also includes a mixing damper mechanism 3. The guide pipe 12 of the ultrasonic atomizer 10, in conjunction with the air outlet pipe of the car's air conditioning system, extends into the mixing damper mechanism 3, removing frost from the windshield. The ultrasonic atomizer 10 generates micron-level water mist, which is transported through the connecting pipe 11 and the guide pipe 12. The water supply mechanism 2 stores water in the buffer cylinder 20 and a pressure pump 23 stably supplies water to the ultrasonic atomizer 10. Finally, the atomized water mist is introduced into the mixing damper mechanism 3, mixed with the hot air from the air conditioning system, and blown onto the windshield for defrosting. By deeply integrating the ultrasonic atomization system with the car's air conditioning duct, utilizing low-temperature water mist to quickly humidify and melt the frost layer, and supplemented by hot air to accelerate evaporation, a highly efficient and energy-saving defrosting effect is achieved.

[0020] like Figure 2 As shown, a water inlet pipe 21 is fixedly connected to the buffer cylinder 20, and the water inlet pipe 21 is used to inject clean water into the buffer cylinder 20. A stabilizing seat 26 is fixedly installed on the bottom surface of the booster pump 23, and the stabilizing seat 26 is fixedly connected to the base 1. The water inlet pipe 21 ensures a continuous water supply for the defrosting system, and the stabilizing seat 26 enhances the operational stability of the booster pump 23, extends the service life of the equipment, and reduces operating noise.

[0021] like Figure 3 and Figure 4As shown, the mixing damper mechanism 3 includes a mounting bracket 30 fixedly connected to the vehicle, and an air inlet 31 is fixedly installed on the mounting bracket 30. The air outlets of the guide pipe 12 and the air outlets of the car air conditioning duct are both located inside the air inlet 31. A control panel 33 is installed on the mounting bracket 30, and a linkage arm 34 is installed on the control panel 33. A control plate 35 is installed on the linkage arm 34, and the control plate 35 is used to open or close the air inlet 31. The atomizing guide pipe 12 and the air conditioning duct converge at the air inlet 31 of the mounting bracket 30, so that the water mist and hot air are initially mixed here. By rotating the control panel 33, the control plate 35 is rotated through the linkage arm 34, thereby precisely adjusting the size of the air inlet 31 and the flow rate of the mixed airflow.

[0022] like Figure 5 As shown, an adjustment component 32 is fixedly installed at the air outlet end of the mounting bracket 30. The adjustment component 32 includes a fixed bracket 320. A movable bracket 321 is damped and hinged on the fixed bracket 320. A control block 322 is slidably installed on the movable bracket 321. A linkage bar 323 is installed on the control block 322. An adjustment bracket 324 that can rotate is installed on the linkage bar 323. A reinforcing bar 325 is rotatably installed on the adjustment bracket 324. The reinforcing bar 325 is fixedly connected to the mounting bracket 30. By sliding the control block 322 and the linkage bar 323, the adjustment bracket 324 can be driven to rotate, thereby causing the movable bracket 321 that is damped and hinged to it to change its angle, so as to realize flexible and multi-angle adjustment of the air outlet direction.

[0023] In summary, when using the automotive air conditioning mixing damper defrosting device with ultrasonic atomization assistance, the pressurizing pump 23 in the water supply mechanism 2 continuously pumps clean water from the buffer cylinder 20 into the ultrasonic atomizer 10. The ultrasonic atomizer 10 breaks the water into micron-sized fine water mist through high-frequency vibration and delivers it to the air inlet 31 of the mixing damper mechanism 3 through the guide pipe 12. At the same time, the warm air generated by the automotive air conditioning system is also guided to the air inlet 31, where the two are initially mixed. Subsequently, the air control plate 35 is manipulated by adjusting the control panel 33 to control the flow rate of the mixed airflow, and the multi-directional adjustable air outlet guide component is used to accurately and evenly blow this humid and warm airflow containing uniform low-temperature water mist onto the windshield surface. The water mist quickly increases the humidity of the glass surface to accelerate the melting of the frost layer, while the warm air provides heat for melting and accelerates the evaporation of the water film, thereby achieving a fast, efficient, and energy-saving defrosting effect.

[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
