Description

Defrosting and defogging systems and vehicles

[0001] This disclosure claims priority to Chinese Patent Application No. 202411203037.4, filed on August 29, 2024, entitled “Defrosting and Defogging System and Vehicle”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of automotive technology, and more particularly to a defrosting and defogging system and vehicle. Background Technology

[0003] When there is a significant temperature difference between the inside and outside of a car, the warmer moisture in the air encounters the cooler glass, causing fogging or frost to form on the glass surface. This obstructs the view of passengers and poses a safety hazard while driving. Therefore, it is necessary to defrost and defog car windows.

[0004] Defrosting and defogging of car windshields typically utilizes a long, narrow air vent located in the center of the dashboard front area. This vent directs airflow from the air conditioning unit upwards onto the windshield to remove fog or frost. However, the shape, size, and location of this vent are constrained by the car's interior design, the dashboard's internal components, and surrounding parts. With increasing automotive electrification and intelligence, more electronic components and larger screens are installed on the dashboard, limiting the size of the air vent and resulting in slower defrosting and defogging speeds. Furthermore, this vent only allows airflow from bottom to top onto the windshield, resulting in relatively low coverage and a longer overall defrosting time.

[0005] Therefore, there is an urgent need to provide an efficient defrosting and defogging solution. Summary of the Invention

[0006] This disclosure provides a defrosting and defogging system and vehicle, which deploys defrosting and defogging air ducts on support pillars on both sides of the vehicle glass. Air is blown onto the vehicle glass through multiple air vents on both sides of the support pillars. The size of the air vents is highly flexible and not limited by the dashboard. Furthermore, the efficiency of defrosting and defogging the vehicle glass is improved by blowing air from both sides and through more air vents. At the same time, the introduction of air valves allows for the selection of the number of air ducts that can be opened, thereby improving the flexibility of defrosting and defogging control.

[0007] To achieve the above objectives, this disclosure provides the following technical solution:

[0008] The first aspect of this disclosure provides a defrosting and defogging system, including a left-side air duct, a right-side air duct, and an air valve; the left-side air duct and the right-side air duct are respectively disposed in support pillars on the left and right sides of the vehicle glass; the support pillars have multiple air vents on the side near the vehicle glass for airflow to be ejected from the left-side air duct and the right-side air duct; both the left-side air duct and the right-side air duct are connected to the outlet of the vehicle's air conditioning unit to transmit the air blown from the air conditioning unit outlet to the vehicle glass through the multiple air vents; the air valve is used to close the air path formed by the left-side air duct or the right-side air duct and the outlet of the air conditioning unit.

[0009] Based on the above technical solution, the present disclosure can be further improved as follows.

[0010] In one possible implementation, the air valve is an electric air valve, which is respectively located at the connection between the left air duct and the outlet of the air conditioning unit, and at the connection between the right air duct and the outlet of the air conditioning unit.

[0011] In one possible implementation, the size of the higher air vent is greater than the size of the lower air vent, or the size of the higher air vent is smaller than the size of the lower air vent.

[0012] In one possible implementation, a plurality of heating wires are further provided in either the left or right air duct. The heating wires are used to heat the air flowing through the air duct, and the plurality of heating wires are deployed along the direction in which the air duct extends.

[0013] In one possible implementation, the plurality of heating wires correspond one-to-one with the plurality of air vents.

[0014] In one possible implementation, the air vent is provided with a grille, the grille including steerable blades.

[0015] In one possible implementation, a heating component is also provided within the grille for heating the air flowing through the grille.

[0016] In one possible implementation, the left-side air duct is also connected to the internal circulation inlet of the air conditioning unit, and the air valve is further used to close or open the air path formed by the left-side air duct and the internal circulation inlet of the air conditioning unit; after the air valve closes the air path formed by the left-side air duct and the outlet of the air conditioning unit, and opens the air path formed by the right-side air duct and the outlet of the air conditioning unit, as well as the air path formed by the left-side air duct and the internal circulation inlet of the air conditioning unit, the right-side air duct and the left-side air duct form a blowing and sucking circulating air path, so that the air blown towards the vehicle window by the right-side air duct is sucked away by the left-side air duct and condensed into liquid by the evaporator of the air conditioning unit before being discharged; or...

[0017] The right-side air duct is also connected to the internal circulation inlet of the air conditioning unit. The air valve is also used to close or open the air path formed by the right-side air duct and the internal circulation inlet of the air conditioning unit. After the air valve closes the air path formed by the right-side air duct and the outlet of the air conditioning unit, and opens the air path formed by the left-side air duct and the outlet of the air conditioning unit, as well as the air path formed by the right-side air duct and the internal circulation inlet of the air conditioning unit, the left-side air duct and the right-side air duct form a blowing and sucking air circulation path, so that the air blown towards the vehicle glass by the left-side air duct is sucked away by the right-side air duct and condensed into liquid by the evaporator of the air conditioning unit and discharged.

[0018] In one possible implementation, the vehicle glass is the vehicle's front windshield and / or rear windshield.

[0019] A second aspect of this disclosure provides a vehicle, including: a vehicle body, an air conditioning unit, vehicle glass, support pillars, and a defrosting and defogging system provided in the first aspect of this disclosure, all disposed on the vehicle body.

[0020] This disclosure provides a defrosting and defogging system and vehicle. The defrosting and defogging system achieves airflow from both sides of the glass to the glass through two air ducts deployed in the support pillars on both sides of the vehicle glass and multiple air vents opened on the support pillars. Compared with airflow from the bottom of the glass to the top, this improves the speed of defrosting and defogging the vehicle glass. Moreover, since the air vents are deployed on the support pillars, they are not easily affected by vehicle interior, screens and other accessories, and can support the configuration of more air vents, and the size of the air vents can be flexibly configured. In addition, by introducing air valves, while airflow is provided from both sides, it is also possible to open only one side of the air duct to save energy and improve the flexibility of defrosting and defogging control.

Detailed Implementation

[0033] In low winter temperatures or high summer temperatures, the large temperature difference between the inside and outside of the car, caused by the air conditioning on or other factors, can easily lead to frost or fogging on the windshield due to the combined effects of low temperatures on the glass surface and moisture in the air. This can impair the driver's visibility and create safety hazards. Therefore, it is necessary to defrost and defog the windshield regularly.

[0034] Figure 1 is a schematic diagram of the structure of a defrost and defog vent in the prior art. As shown in Figure 1, in the prior art, the defrost and defog vent is deployed at the front of the car dashboard, below the windshield. The hot air blown out by the air conditioner is blown onto the windshield through the defrost and defog vent to achieve the effect of defrosting and defogging.

[0035] Defrosting and defogging vents can be deployed on one side or in the middle of the dashboard, blowing hot air upwards toward the windshield, as shown by the arrows in Figure 1. Using a bottom-up, unidirectional airflow for defrosting and defogging results in a longer overall defrosting and defogging time and lower efficiency.

[0036] Meanwhile, the location and size of the defrosting and defogging vents deployed at the front of the dashboard are constrained by the car's interior design, the dashboard's interior and surrounding parts, and cannot be too large, resulting in less hot air being blown onto the windshield and a slower defrosting and defogging speed.

[0037] In addition, with the increasing popularity of ultra-large in-vehicle screens, there will be situations where space is limited and it is impossible to install the aforementioned defrosting and defogging vents.

[0038] To address the aforementioned technical problems, this disclosure provides a defrosting and defogging system. By deploying two air ducts (a left-side duct and a right-side duct) within the support pillars on both sides of the vehicle glass (such as A-pillars and C-pillars), and multiple air vents on the support pillars, air is blown onto the glass from both sides. Compared to blowing air upwards from below the glass, this increases the speed of defrosting and defogging the vehicle glass. Furthermore, since the air vents are deployed on the support pillars, multiple vents can be deployed along the direction of the support pillars. The deployment position and size are not affected by the dashboard interior or surrounding components such as the screen, supporting a large number of vents with flexible size configuration. Additionally, by introducing air valves, it is possible to open only one side of the air duct while blowing air from both sides, saving energy and improving the flexibility of defrosting and defogging control.

[0039] To make the above-mentioned objects, features, and advantages of the embodiments of this disclosure more apparent and understandable, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0040] The specific structure of the defrosting and defogging system and the vehicle provided in the embodiments of this disclosure will be described below with reference to the accompanying drawings.

[0041] Figure 2 is a schematic diagram of a defrosting and defogging system provided in an embodiment of the present disclosure. As shown in Figure 2, the defrosting and defogging system includes a left air duct 210, a right air duct 220, and an air valve 230.

[0042] The left-side air duct 210 and the right-side air duct 220 are respectively located within the support pillars 110 on the left and right sides of the vehicle glass 100. Multiple air vents 111 are provided on the side of the support pillar 110 closest to the vehicle glass 100 to allow airflow from the left-side air duct 210 and the right-side air duct 220 to exit. Figure 2 shows an example with three air vents 111 on each support pillar. Both the left-side air duct 210 and the right-side air duct 220 are connected to the vehicle's air conditioning unit outlet 310, allowing air blown from the air conditioning unit outlet 310 to be transmitted to the vehicle glass 100 through the multiple air vents 111. The air valve 230 is used to close the air path formed by the left-side air duct 210 or the right-side air duct 220 and the air conditioning unit outlet 310, i.e., to close air path A1 or air path A2. Air path A1 is the air path formed by the air conditioning unit outlet 310 and the left-side air duct 210, while air path A2 is the air path formed by the air conditioning unit outlet 310 and the right-side air duct 220.

[0043] The vehicle glass 100 can be any one or more pieces of glass on the vehicle, such as the windshield or the rear windshield. Correspondingly, the support pillar 110 can be an A-pillar (front pillar) or a C-pillar (rear pillar).

[0044] Multiple air vents 111 provided on the support column 110 can be deployed along the direction of extension of the support column 110, with the multiple air vents 111 spaced apart. Correspondingly, the left air duct 210 and the right air duct 220 also have openings at positions corresponding to the air vents 111 to form air ducts, so as to spray the air blown out of the air conditioning unit outlet 310 onto the vehicle glass 100.

[0045] Multiple air vents 111 can be evenly deployed along the direction of the support column 110, and the size of each air vent 111 can be the same.

[0046] The air vent 111 can have openings for the grille to accommodate it. The direction of the airflow ejected from the air vent 111 can be adjusted by adjusting the guide of the grille blades.

[0047] The left air duct 210 and the right air duct 220 are connected to or connected to the air conditioning unit outlet 310 at the bottom end, i.e., the inlet, to obtain airflow from the air conditioning unit.

[0048] During the defrosting and defogging process, the speed of the blower in the air conditioning unit can be adjusted as needed, thereby controlling the air volume of the upper air outlet 111 of the support column 110.

[0049] In one possible implementation, the left air duct 210 and the right air duct 220 can be symmetrical about the vehicle glass 100, thereby simplifying the production of the left air duct 210 and the right air duct 220.

[0050] The vehicle glass 100 is defrosted and defogged by air ducts located on the left and right sides of the vehicle glass 100, which realizes bidirectional air blowing and greatly improves the speed of defrosting and defogging. This allows the vehicle to eliminate the air vents located at the front of the dashboard, thereby freeing up space at the front of the dashboard and allowing more accessories and designs to be accommodated.

[0051] The air valve 230 can be either a manual air valve or an electric air valve.

[0052] In some embodiments, there may be one air valve 230. The inlet of the air valve 230 is connected to the outlet 310 of the air conditioning unit, and the two outlets of the air valve 230 are respectively connected to the inlet of the left air duct 210 and the inlet of the right air duct 220. The valve plate inside the air valve 230 includes three states: a first state, a second state, and a third state. The first state is the default state. In the first state, the air ducts corresponding to the left air duct 210 and the right air duct 220 are both opened, and the air blown out of the air conditioning unit outlet 310 flows through the inlet of the air valve 230. In the second state, the air path A1 corresponding to the left air path 210 is opened and the air path A2 corresponding to the right air path 220 is closed, and the air blown out of the air conditioning unit outlet 310 flows to the left air path 210 through the inlet of the air valve 230; in the third state, the air path A2 corresponding to the right air path 220 is opened and the air path A1 corresponding to the left air path 210 is closed, and the air blown out of the air conditioning unit outlet 310 flows to the right air path 220 through the inlet of the air valve 230.

[0053] In other embodiments, there may be two air valves 230, which are respectively installed in the left air duct 210 and the right air duct 220 to close or open the corresponding air passage.

[0054] For example, the air valve 230 can be set at the connection between the left air duct 210 or the right air duct 220 and the air conditioning unit outlet 310 to close or open air duct A1 and air duct A2.

[0055] In one possible implementation, the air valve 230 is an electric air valve, which is respectively located at the connection between the left air duct 210 and the air conditioning unit outlet 310, and at the connection between the right air duct 220 and the air conditioning unit outlet 310.

[0056] The use of an electric air valve enables automatic control of the airflow path opening and closing, allowing users to control the valve's status via vehicle buttons or virtual buttons on a touchscreen, thus improving operational convenience. Furthermore, both airflow paths are controlled by separate air valves 230, resulting in a low-complexity system structure and rich control functions.

[0057] During defrosting and defogging, if the air valves 230 in both air ducts are open, the air or airflow blown out of the air conditioning unit outlet 310 will be sprayed onto the vehicle glass 100 through the air paths corresponding to the left air duct 210 and the right air duct 220, namely air path A1 and air path A2, respectively, and thus achieve defrosting and defogging of the vehicle glass 100.

[0058] During defrosting and defogging, if only one air duct valve 230 is open, the air or airflow blown out of the air conditioning unit outlet 310 will be sprayed from multiple air vents 111 on the support column 110 through the open air duct, such as the air duct corresponding to the right air duct, onto the vehicle glass 100, thereby achieving defrosting and defogging of the vehicle glass 100.

[0059] Users can adjust the state of the air valve 230 based on the frosting or fogging condition of the vehicle glass 100, thereby selecting which air path to open. For example, when only the left side of the vehicle glass 100 is frosted, the air valve 230 in the right air duct 220 can be closed, thereby opening only the air path A1 for defrosting and avoiding energy waste caused by opening both air paths.

[0060] The defrosting and defogging system provided in this embodiment achieves airflow from both sides of the vehicle glass to the vehicle glass through two air ducts deployed in the support pillars on both sides of the vehicle glass and multiple air vents opened on the support pillars. Compared with the method of airflow from the bottom of the vehicle glass to the top, this improves the speed of defrosting and defogging the vehicle glass. Moreover, since the air vents are deployed on the support pillars, they are not easily affected by vehicle interior, screens and other accessories, and can support the configuration of more air vents, and the size of the air vents can be flexibly configured. In addition, through the introduction of air valves, while airflow is blowing from both sides, it is also possible to open only one side of the air duct to save energy and improve the flexibility of defrosting and defogging control.

[0061] Based on the above embodiments, the dimensions of multiple air vents opened on the same support column 110 can include various dimensions, such as different dimensions of each air vent, or different dimensions of some air vents, thereby controlling the speed and flow distribution of airflow blowing towards different areas of the vehicle glass 100.

[0062] Figure 3A is a structural schematic diagram of one implementation of multiple air vents on the support column in the embodiment shown in Figure 2 of this disclosure, and Figure 3B is a structural schematic diagram of another implementation of multiple air vents on the support column in the embodiment shown in Figure 2 of this disclosure. Both Figure 3A and Figure 3B use 7 air vents 111 as an example, but the number of air vents can also be other numbers, such as 5 or 6, which can be adjusted according to requirements.

[0063] Referring to Figure 3A, the size of the higher air vent 111 on the support column 110 is larger than that of the lower air vent 111. That is, the size of the air vent 111 on the same support column 110 increases in order of height from low to high, such as linearly or non-linearly.

[0064] The multiple air vents 111 designed in this way are more suitable for vehicle windows 100 with large tilt angles and long lengths, which can improve the defrosting and defogging speed of such vehicle windows 100. The length of the vehicle window 100 is the length of the long side of the vehicle window, which is usually the length along the left and right direction of the vehicle window 100.

[0065] Referring to Figure 3B, the size of the higher air vent 111 on the support column 110 is smaller than that of the lower air vent 111. That is, the size of the air vent 111 on the same support column 110 decreases in order of height from low to high, such as linearly or non-linearly.

[0066] The multiple air vents 111 designed in this way are more suitable for vehicle windows 100 with small tilt angles and short lengths, which can improve the defrosting and defogging speed of such vehicle windows 100. The length of the vehicle window 100 is the length of the long side of the vehicle window, which is usually the length along the left and right direction of the vehicle window 100.

[0067] For example, for a vehicle glass 100 with a tilt angle greater than or equal to a first angle and a length greater than or equal to a first length, the size of the higher air vent 111 among the plurality of air vents 111 on the support pillar 110 of the vehicle glass 100 is larger than the size of the lower air vent 111. For a vehicle glass 100 with a tilt angle less than a second angle and a length less than a second length, the size of the higher air vent 111 among the plurality of air vents 111 on the support pillar 110 of the vehicle glass 100 is smaller than the size of the lower air vent 111. The second angle is less than or equal to the first angle, and the second length is less than or equal to the first length.

[0068] Figure 4 is a schematic diagram of a duct structure provided in an embodiment of the present disclosure. As shown in Figure 4, the duct, such as the left duct 210 or the right duct 220 mentioned above, includes a duct body 21 and a plurality of air guide sections 22 disposed on the duct body 21. The air guide sections 22 correspond one-to-one with the air outlets 111 and are connected to the corresponding air outlets 111 for airflow to be ejected.

[0069] The air guide section 22 can be horizontal or inclined. By using air guide sections 22 with different orientations, the direction of the airflow ejected from the air outlet 111 can be adjusted.

[0070] Figure 4 shows that the air guide section 22 is a horizontal air guide section, that is, the direction of the airflow from the air guide section 22 to the corresponding air outlet 111 is horizontal. Figure 5 is a structural schematic diagram of the inclined air guide section provided in the embodiment of this disclosure, with the air guide section 22 oriented diagonally downward as an example.

[0071] In practical applications, the tilt angle of the air guide section 22 can be set based on the desired airflow distribution.

[0072] In some embodiments, the tilt angles of the multiple air guide sections 22 in a duct can be multiple. For example, the middle air guide section 22 can be horizontal, i.e., the tilt angle is 0°, and the tilt angles of the other air guide sections 22 are related to the distance between the air guide section 22 and the middle air guide section 22 or the number of air guide sections 22 that are spaced apart.

[0073] Taking five air guide sections as an example, the tilt angles of each air guide section from top to bottom are -30°, -15°, 0°, 15° and 30°, thereby accelerating the defrosting and defogging speed of the middle area of ​​the vehicle glass 100.

[0074] The length of the air guide section 22 can be selected according to the size of the vehicle glass 100. Selecting an appropriate length of air guide section 22 can help optimize the air velocity of the airflow ejected from the air vent 111, thereby optimizing the air velocity distribution on the vehicle glass 100 and improving the defrosting and defogging speed. The air guide section 22 of the air duct shown in Figure 5 is longer than the air guide section 22 of the air duct shown in Figure 4.

[0075] Figure 6 is a schematic diagram of another defrosting and defogging system provided in this embodiment. Referring to Figures 2 and 6, in this embodiment, multiple heating wires 23 are also provided in the left air duct 210 and the right air duct 220. The heating wires 23 are used to heat the flowing air or airflow, thereby increasing the temperature of the air blown onto the vehicle glass 100 by the air vent 111 and accelerating the defrosting and defogging speed of the vehicle glass 100. Figure 6 shows an example where the right air duct 220 is closed by the air valve 230, thus utilizing only the left air duct 210 to blow air from the left side of the vehicle glass 100 for defrosting and defogging.

[0076] Heating wires 23 may be deployed at at least some of the air vents 111, such as at the third air vent 111 and all air vents above the third air vent 111 in a bottom-to-top order.

[0077] In one possible design, multiple heating wires 23 correspond one-to-one with multiple air vents 111. Referring to Figure 6, the heating wires 23 and air vents 111 are aligned, and each air vent 111 is provided with a heating wire 23. By placing the heating wires 23 adjacent to the air vents, heat loss during the transfer process is avoided, thus saving energy.

[0078] The number and position of the heating wires 23 can be configured according to requirements, and this disclosure does not limit them.

[0079] Figure 7 is a structural schematic diagram of another defrosting and defogging system provided in an embodiment of this disclosure. As can be seen from Figures 2 and 7, in this embodiment, a grille is also provided at the air outlet 111, and the grille includes rotatable blades 112.

[0080] The direction of airflow from the vent 111 can be adjusted by the rotatable blades 112 inside the grille. Figure 7 takes the horizontal blades 112 of the grille at the vent 111 corresponding to the left air duct 210 as an example. Thus, the left air duct 210 blows air horizontally toward the vehicle glass 100 through multiple vents 111 on the left support column 110. The blades 112 of the grille at the vent 111 corresponding to the right air duct 220 are angled downwards. Thus, the right air duct 220 blows air obliquely toward the vehicle glass 100 through multiple vents 111 on the right support column 110.

[0081] The direction of the grille blades 112 can be adjusted manually or via buttons or virtual buttons on the vehicle.

[0082] In some embodiments, a grille may be placed at each air vent 111 to allow for individual adjustment of the direction of the airflow from each air vent 111.

[0083] In other embodiments, the same support column 110 may correspond to a grille, that is, the grille covers multiple air vents 111 on the support column 110.

[0084] The grid can include two types of blades: one type is blades with a fixed direction, and the other type is blades that can be steered, namely blade 112.

[0085] In some embodiments, the grille has a sweeping function, which is achieved by continuously adjusting the grille blades to move back and forth in one or more directions. This sweeping function ensures that the vehicle glass 100 receives airflow evenly, and when the blown air is at a higher temperature, the overall temperature of the vehicle glass 100 remains at a higher level, reducing the probability of frost or fogging on the vehicle glass 100.

[0086] The air-sweeping function can achieve rapid defogging over a large area, thus achieving the goal of rapid defrosting and defogging using a smaller airflow path.

[0087] By adjusting the direction of the blades 112, the airflow distribution directed toward the vehicle glass 100 is adjusted, thereby improving the flexibility of defrosting and defogging the vehicle glass 100.

[0088] In one possible design, a heating element is also provided within the grille for heating the air flowing through it. The heating element may include heat exchange tubes or heating wires.

[0089] When using the air blown out of the air conditioning unit outlet 310 to defrost and defog the vehicle glass 100, the air blown out of the air conditioning unit outlet 310 passes through the left air duct 210 and the right air duct 220, and reaches multiple air vents 111 on the support pillars 110 on both sides of the vehicle glass 100. After being heated by the heating components in the grille at the air vent 111, the hot air is blown towards the vehicle glass 100 through the grille at the air vent 111.

[0090] By deploying the heating components inside the grille, the proximity of the heating components to the air vent 111 is further improved, reducing heat loss of the heated airflow and saving energy.

[0091] Taking the vehicle glass 100 as the windshield as an example, the support pillar 110 is the A-pillar. When a panoramic, widescreen, or projection display device is arranged at the front of the vehicle's dashboard, the above-mentioned defrosting and defogging system designed with the A-pillar can eliminate the defrosting air vents originally arranged at the front of the dashboard. By using the air ducts (left air duct 210 and right air duct 220) and multiple air vents 111 on the left and right A-pillars, air can be blown from the left and right sides to the windshield, thereby effectively avoiding the spatial conflict between the display device and defrosting and defogging, making reasonable use of the empty space on both sides of the windshield, and achieving a rapid defrosting and defogging effect.

[0092] Figure 8 is a schematic diagram of the airflow guidance of the defrosting and defogging system provided in this embodiment. Airflow is represented by arrowed lines in Figure 8. As shown in Figure 8, the display device is located in front of the steering wheel, and its screen is large, almost the width of the windshield. The air blown from the air conditioning unit outlet 310 flows along the left air duct 210 and the right air duct 220, respectively, and is blown towards the windshield from both sides through the air vents 111. The airflow can bypass the display device and be guided to both sides through the air ducts within the A-pillars on both sides of the windshield. Simultaneously, based on the air vents on the A-pillars, the airflow is not interfered with by the large screen of the display device during its guidance to the windshield, ensuring the effectiveness of defrosting and defogging.

[0093] Figure 9 is a schematic diagram of another defrosting and defogging system provided in this embodiment. Referring to Figures 2 to 9, in this embodiment, one of the left air duct 210 and the right air duct 220 is used for blowing air, while the other is used for suction air. The suction air duct, such as the left air duct 210 or the right air duct 220, is connected to the internal circulation inlet 320 of the air conditioning unit, forming an integrated blowing and suction defrosting and defogging system. The solid dots in Figure 9 represent water vapor in the humid air.

[0094] To prevent the air conditioning unit from blowing out the humid air it draws in directly, which would affect the efficiency of defrosting and defogging, the evaporator of the air conditioning unit also needs to have a cooling function to condense the humid air that enters the evaporator through the internal circulation inlet 320 into liquid and discharge it, thereby maintaining the dry airflow blown out of the air conditioning unit outlet 310 and improving the efficiency of defrosting and defogging.

[0095] The air duct blows hot air from the air conditioning unit outlet 310 onto the vehicle glass 100. The humid air that has passed through the vehicle glass 100 is drawn into the internal circulation of the air conditioning unit through the air vent 111 on the support column 110 where the air intake duct is located. The air is then condensed into liquid water by the air conditioning unit evaporator and discharged.

[0096] Figure 9 shows an example where the blowing air duct is the left air duct 210 and the suction air duct is the right air duct 220. In this case, the right air duct 220 is also connected to the internal circulation inlet 320 of the air conditioning unit. The air valve 230 is also used to close or open the air path A3 formed by the right air duct 220 and the internal circulation inlet 320 of the air conditioning unit. After the air valve 230 closes the air path formed by the right air duct 220 and the air conditioning unit outlet 310, and opens the air path formed by the left air duct 210 and the air conditioning unit outlet 310, as well as the air path formed by the right air duct 220 and the internal circulation inlet 320 of the air conditioning unit, the air valve 230 controls the opening of air path A1, the opening of air path A3, and the closing of air path A2. The left air duct 210 and the right air duct 220 form a blowing and suction circulation air path, so that the air blown towards the vehicle glass 100 by the left air duct 210 is sucked away by the right air duct 220 and condensed into liquid by the evaporator of the air conditioning unit and discharged.

[0097] In other embodiments, the left air duct 210 can be configured as an air intake duct, and the right air duct 220 as an air blowing duct. In this case, the left air duct 210 is also connected to the internal circulation inlet 320 of the air conditioning unit, and the air valve 230 is also used to close or open the air path A4 formed by the left air duct 210 and the internal circulation inlet 320 of the air conditioning unit. After the air valve 230 closes the air path formed by the left air duct 210 and the air conditioning unit outlet 310, and opens the air path formed by the right air duct 220 and the air conditioning unit outlet 310, as well as the air path formed by the left air duct 210 and the internal circulation inlet of the air conditioning unit, the air valve 230 controls the opening of air path A2, the opening of air path A4, and the closing of air path A1. The right air duct 220 and the left air duct 210 form a blowing and suction circulation air path, so that the air blown towards the vehicle glass 100 by the right air duct 220 is drawn away by the left air duct 210 and condensed into liquid by the evaporator of the air conditioning unit and discharged.

[0098] The airflow circulation path formed by the air ducts in the support pillars 110 on both sides of the vehicle glass 100 achieves airflow from one side and airflow from the other side, further accelerating the defrosting and defogging speed of the vehicle glass 100. At the same time, the cooling function of the air conditioning unit is used to condense the humid air drawn into its internal circulation into liquid water, preventing humid air from being blown onto the vehicle glass 100 through the air conditioning unit outlet 310 and the airflow duct, ensuring the dryness of the air blown onto the vehicle glass 100, thereby improving the defrosting and defogging efficiency.
