[0002] In the use scenario of vehicle air conditioning, there may be a need for both external and internal air intake and blowing out from different air outlets. For example, in winter, the external air intake draws in dry cold air from outside the passenger compartment, blows out from the defrost outlet after heat exchange for defrosting, while the internal air intake draws in warm air from inside the passenger compartment, blows out from the foot outlet after heat exchange to increase the temperature inside the passenger compartment. This requires the vehicle's air conditioning box to form two completely independent air ducts and use two independent air duct components, such as two fans, which results in the vehicle's air conditioning box having many components, a complex structure, and a large volume.

[0032] Embodiments of the present application provide an air conditioning box, an air conditioning assembly, and a vehicle.

[0033] The vehicle according to the embodiment of the present application includes the above-mentioned air-conditioning box or the above-mentioned air-conditioning assembly.

[0034] The vehicle may be a pure electric vehicle, a hybrid vehicle, a fuel vehicle, etc. This application does not limit the form of the vehicle.

[0035] The air conditioning assembly of the embodiment of the present application is applied to a vehicle and includes the above-mentioned air conditioning box.

[0036] The air conditioning assembly applied to the vehicle can be used to adjust the air environment in the passenger compartment of the vehicle, such as increasing or decreasing the air temperature in the passenger compartment, increasing or decreasing the air humidity in the passenger compartment, and reducing the air suspended matter in the passenger compartment. Generally, the air conditioning assembly may include a compressor driven by the vehicle power, which may provide power for the flow of the refrigerant in the evaporator and the condenser and change the pressure and temperature of the refrigerant to achieve heat exchange at the evaporator and the condenser. The air conditioning assembly also includes some air circuit mechanisms, and the air conditioning box 1000 is at least part of the air circuit mechanism.

[0037] Please refer to Figure 1 and Figure 2 The air conditioning box 1000 of the embodiment of the present application is applied to the air conditioning assembly of the vehicle, and includes a housing 100 and a cross-flow fan 200. The housing 100 is formed with a first air inlet 111, a second air inlet 112, a first air duct 121 and a second air duct 122. The cross-flow fan 200 is arranged in the housing 100 and cooperates with the housing 100, so that when the first air inlet 111 and the second air inlet 112 are opened at the same time, the cross-flow fan 200 draws air from the first air inlet 111 to form a first laminar flow 310 blowing into the first air duct 121, and draws air from the second air inlet 112 to form a second laminar flow 320 blowing into the second air duct 122, as shown in FIG. Figure 2 As shown, the arrow in the figure indicates the direction of air flow.

[0038] The air inlet and outlet air flows of the cross-flow fan 200 are both in a laminar state, so that the cross-flow fan 200 can inhale air from the first air inlet 111 on the housing 100 to form a first laminar flow 310, and inhale air from the second air inlet 112 to form a second laminar flow 320. There is basically no gas exchange between the laminar flows, so that although the first laminar flow 310 and the second laminar flow 320 are adjacent, the gases of the first laminar flow 310 and the second laminar flow 320 do not exchange with each other, so the gas properties in the first laminar flow 310 and the second laminar flow 320 can be maintained. The first air inlet 111 can be connected to the outside of the vehicle, and the second air inlet 112 can be connected to the passenger compartment, so the first laminar flow 310 and the second laminar flow 320 can come from the outside of the vehicle and the passenger compartment respectively, and the first air duct 121 and the second air duct 122 can lead to different positions in the passenger compartment respectively to realize the separate utilization of external gas and internal gas. Therefore, the air conditioning box 1000 of the present application can meet the needs of both external circulation air intake and internal circulation air intake at the same time, and the external circulation air intake and the internal circulation air intake are independent of each other, but only one cross-flow fan 200 is required, so that the components of the air conditioning box 1000 are reduced, the structure is simplified, and the volume is reduced.

[0039] The housing 100 is a component through which air can pass. The housing 100 may have an opening. The air enters the housing 100 through the first air inlet 111 or the second air inlet 112, and then blows out of the housing 100 from the opening to enter the passenger compartment. Therefore, the first laminar flow 310 and the second laminar flow 320 may not be divided in the housing 100. After the first laminar flow 310 and the second laminar flow 320 flow out of the housing 100, other flow division mechanisms, such as a Y-shaped pipe, divide the first laminar flow 310 and the second laminar flow 320 so that the first laminar flow 310 and the second laminar flow 320 flow to different positions in the passenger compartment.

[0040] There may be no physical partition between the first air duct 121 and the second air duct 122, for example, the partition 140 mentioned below may not be provided. In such an embodiment, the actual distinction between the first air duct 121 and the second air duct 122 can be determined by the space in which the laminar flow directed to different positions in the passenger compartment actually flows in the housing 100. In one example, the air conditioning assembly in the passenger compartment directs the gas from the housing 100 to the defrost outlet and the foot outlet, wherein the defrost outlet is an outlet facing the front windshield, rear windshield or side glass, and the foot outlet is an outlet that can be directed to the bottom of the seat, or at least below the height of the door interior panel along the z-axis direction of the vehicle. The flow space in the housing 100 of the air flow blown out of the defrost outlet and the flow space in the housing 100 of the air flow blown out of the foot outlet can be the first air duct 121 and the second air duct 122, respectively.

[0041] Please refer to Figure 5 and Figure 6 The impeller 210 of the crossflow fan 200 rotates and cooperates with the housing 100 to Figure 2 An eccentric vortex 201 is generated near the volute tongue 150 shown in the figure, and outside the eccentric vortex 201, the air flow streamline will show the characteristics of arc-shaped stratified flow. Therefore, the cross-flow fan 200 can cooperate with the shell 100 to produce a first laminar flow 310 and a second laminar flow 320. There is basically no gas exchange between the first laminar flow 310 and the second laminar flow 320, which can ensure that the gas properties in the two laminar flows do not merge. In addition, the cross-flow fan 200 can also be a power source for the gas. For example, when the vehicle starts the internal circulation, the gas in the passenger compartment needs to pass through the shell 100 and then be sent back to the passenger compartment. The gas in the passenger compartment is almost stationary relative to the vehicle, so an additional power source is required to drive the gas flow. The cross-flow fan 200 can drive the gas flow, Figure 5 The arrow in the middle indicates the direction of air flow.

[0042] Please refer to Figure 3 In some embodiments, when only the first air inlet 111 is opened, the crossflow blower 200 draws air from the first air inlet 111 to form a total laminar flow 330 and blows air into the first air duct 121 to form a first laminar flow 331 and into the second air duct 122 to form a second laminar flow 332. Figure 3 The arrow in the middle indicates the direction of air flow.

[0043] Turbulent flow is prone to intense friction with the shell wall of the housing 100, resulting in increased resistance of the airflow in the housing 100. The crossflow fan 200 is used to suck air from the first air inlet 111 to form a total laminar flow 330, and the total laminar flow 330 passes through the crossflow fan 200 to form a first stratified flow 331 and a second stratified flow 332, both of which can have a movement direction substantially parallel to the inner wall surface of the housing 100, thereby effectively reducing the interaction between the airflow and the housing 100, reducing the gas flow resistance, and thus increasing the air intake.

[0044] Please refer to Figure 4 When only the second air inlet 112 is opened, the crossflow fan 200 sucks air from the second air inlet 112 to form a total laminar flow 330, blows air into the first air duct 121 to form a first laminar flow 331, and blows air into the second air duct 122 to form a second laminar flow 332. Figure 4 The arrow in the middle indicates the direction of air flow.

[0045] Turbulent flow is prone to intense friction with the shell wall of the housing 100, resulting in increased resistance of the airflow in the housing 100. The crossflow fan 200 is used to suck air from the first air inlet 111 to form a total laminar flow 330, and the total laminar flow 330 passes through the crossflow fan 200 to form a first stratified flow 331 and a second stratified flow 332, both of which can have a movement direction substantially parallel to the inner wall surface of the housing 100, thereby effectively reducing the interaction between the airflow and the housing 100, reducing the gas flow resistance, and thus increasing the air intake.

[0046] Since the different laminar flows of gas have a high degree of independence, the first laminar flow 331 and the second laminar flow 332 do not necessarily need to be spaced apart from each other, but can be connected. The flow directions of the first laminar flow 331 and the second laminar flow 332 are substantially parallel, so a gas separation structure can be set in front of the first laminar flow 331 and the second laminar flow 332 to separate the gases in the first laminar flow 310 and the second laminar flow 320. At this time, the purpose of separating the first laminar flow 310 and the second laminar flow 320 is not to maintain the independence of the gas properties, but to allow the first laminar flow 310 and the second laminar flow 320 to be better processed by the air conditioning system. In an example, please refer to Figure 3 Since the partition 140 is provided to separate the first laminar flow 310 and the second laminar flow 320, the second laminar flow 320 and the first laminar flow 310 can pass through the heat exchanger 500 and the heater core 600 respectively. In this way, if the refrigerant in the heat exchanger 500 flows unevenly, resulting in uneven temperatures in various parts of the heat exchanger 500, or the heater core 600 is partially damaged, resulting in partial heating of the heater core 600, it can be ensured that at least one of the first laminar flow 310 or the second laminar flow 320 is ideally processed, thereby ensuring that the air-conditioning assembly can work normally and improving the stability of the operation of the air-conditioning assembly.

[0047] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the air conditioning box 1000 includes an air intake damper assembly 400 , which is disposed in the housing 100 and configured to adjust the openings of the first air intake port 111 and the second air intake port 112 .

[0048] The first air inlet 111 and the second air inlet 112 share a damper assembly, and the first damper assembly simultaneously controls the opening of the first air inlet 111 and the second air inlet 112, thereby further reducing the number of components of the air-conditioning box 1000, simplifying the structure of the air-conditioning box 1000, and reducing the volume of the air-conditioning box 1000.

[0049] The air intake damper group 400 may include two dampers, and the two dampers may be linked to each other, so that only one driving component (such as a motor) is needed to drive the opening and closing of the two dampers, and the two dampers may respectively cover the first air inlet 111 and the second air inlet 112. At the same time, when the dampers are rotated to different angles, the first air inlet 111 and the second air inlet 112 may be opened to different degrees, so that the first air inlet 111 and the second air inlet 112 are controlled at the same time relative to setting up one air intake damper group 400.

[0050] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the housing 100 includes a tubular air inlet 110. The air inlet 110 is in communication with the crossflow blower 200. A first air inlet 111 is formed at one end of the air inlet 110 away from the crossflow blower 200. An opening is provided on the side wall of the air inlet 110 to form a second air inlet 112. The air inlet damper assembly 400 includes an air inlet damper 410 rotatably disposed in the air inlet 110 and an air inlet drive, the air inlet damper 410 being used to shield the first air inlet 111 and the second air inlet 112, and the air inlet drive being used to drive the air inlet damper 410 to rotate so that the air inlet damper 410 rotates between a position where the first air inlet 111 is completely shielded and a position where the second air inlet 112 is completely shielded.

[0051] One end opening of the tubular air inlet portion 110 is utilized as the first air inlet 111, and an opening is formed on the side wall of the air inlet portion 110 to form the second air inlet 112. Compared with only one opening (opening the second air inlet 112), two air inlets can be formed; the air inlet damper group 400 only has one air inlet damper 410, and the air inlet damper 410 can be rotated by the air inlet driving member to realize the control of the opening of the two dampers, so that the formation of the first air inlet 111 and the second air inlet 112 is simple, and the number of components of the air inlet damper group 400 is reduced, thereby further simplifying the structure of the air conditioning box 1000, reducing the volume of the air conditioning box 1000 or reducing the manufacturing cost of the air conditioning box 1000.

[0052] Please refer to Figures 2 to 4 , wherein the air intake damper 410 is a barrel-shaped damper 930; Figure 3 In the state shown, the air intake damper 410 is in a position to completely shield the second air intake port 112 (the first air intake port 111 is completely open); Figure 4 In the state shown, the air intake damper 410 is in a position to completely shield the first air intake port 111 (the second air intake port 112 is completely open); Figure 2 In the state shown, the air intake damper 410 simultaneously opens the first air intake port 111 and the second air intake port 112. It can be seen that only one air intake damper 410 is needed to simultaneously control the opening of the first air intake port 111 and the second air intake port 112.

[0053] The air intake damper 410 may also be a butterfly damper 910 or a flag damper 920. For the structures of the butterfly damper 910, the flag damper 920 and the barrel damper 930, please refer to Figure 7 , Figure 8 and Fig. 9 .

[0054] Please refer to Figure 2 and Figure 3 In some embodiments, the housing 100 includes a wind wheel mounting portion 130 and a main body 120, both of which are tubular, and the wind wheel mounting portion 130 is connected to the first air inlet 111, the second air inlet 112 and the main body 120; the crossflow fan 200 is arranged in the wind wheel mounting portion 130; the housing 100 also includes a partition 140, which is basically parallel to the first laminar flow 310 and the second laminar flow 320 or the first stratified flow 331 and the second stratified flow 332, and is arranged in the main body 120; the first air duct 121 and the second air duct 122 are respectively located on both sides of the partition 140.

[0055] In this way, two air ducts, namely the first air duct 121 and the second air duct 122, can be formed in the main body 120 through a partition 140. There is no need to set two tubular parts to form the first air duct 121 and the second air duct 122 respectively, so that the structure of the air conditioning box 1000 is further simplified.

[0056] Tubular means a shape with an air inlet, an air outlet and an air passage, and is not a geometrically circular tube. Figure 4 In the illustrated embodiment, the main body 120 has an inlet for entering the first laminar flow 310 and the second laminar flow 320, and also has outlets such as the face-blowing air outlet 126, the foot-blowing air outlet 127 and the defrost air outlet 125 for blowing out the first laminar flow 310 or the second laminar flow 320, and is therefore tubular.

[0057] Similarly, please refer to Figure 2 or Figure 3The wind wheel mounting portion 130 allows the first laminar flow 310, the second laminar flow 320 or the total laminar flow 330 to enter, and also has an outlet for the first laminar flow 310, the second laminar flow 320 or the total laminar flow 330 to flow into the main body 120, so it is also tubular.

[0058] In some embodiments, an air conditioning filter may be disposed before the cross flow fan 200 or before the heat exchanger 500 .

[0059] Please refer to Figure 2 and Figure 3 In some embodiments, the main body 120 includes a first side wall 123 connected to the wind wheel mounting portion 130, and the first side wall 123 is bent and connected to the wind wheel mounting portion 130 to form a volute tongue 150, and the bending angle of the volute tongue 150 is greater than or equal to 30° and less than or equal to 120°.

[0060] Since the air outlet direction of the crossflow fan 200 is equivalent to the circumference of the eccentric vortex 201, the air outlet is not along the circumference of the wind wheel. Therefore, if the bending angle of the volute tongue 150 is too small, the first side wall 123 will not be able to effectively guide the air outlet of the crossflow fan 200, which is easy to generate turbulence; if the bending angle of the volute tongue 150 is too large, the first side wall 123 may hinder the air outlet and increase the exhaust resistance. When the bending angle of the volute tongue 150 is greater than or equal to 30° and less than or equal to 120°, the first side wall 123 can provide guidance for the exhaust of the crossflow fan 200 to avoid the generation of turbulence, and will not hinder the exhaust of the crossflow fan 200, so that the working efficiency of the crossflow fan 200 can be improved, and the formation of horizontal flow can be promoted at the same time.

[0061] In one example, the bending angle of the volute tongue 150 can be 30°, 35°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 115°, or 120°.

[0062] The bending angle of the volute tongue 150 can be as follows: Figure 2 In the cross section shown (the cross section is perpendicular to the axial direction of the wind wheel of the crossflow blower 200), the angle between the first side wall 123 and the wind wheel mounting portion 130 is the angle at the tip of the volute tongue 150. In an example, please refer to Figure 3 , Figure 3 The angle α shown in Figure 3 The bending angle of the volute tongue 150 in the embodiment.

[0063] Please refer to Figure 2 and Figure 3In some embodiments, the main body 120 includes a second side wall 124 connected to the wind wheel mounting portion 130 , the second side wall 124 is opposite to the first side wall 123 , and extends along the tangential direction of the wind wheel mounting portion 130 and then bends in a direction away from the first side wall 123 .

[0064] In this way, the distance between the first side wall 123 and the second side wall 124 gradually increases along the flow direction of the first laminar flow 310 or the first stratified flow 331, forming a flared shape, so that the first airway and the second airway can also have a flared shape, so that the pressure of the first laminar flow 310 or the first stratified flow 331 flowing in the first airway and the pressure of the second laminar flow 320 or the second stratified flow 332 flowing in the second airway can be reduced, which can improve the working efficiency of the air conditioner 1000. In addition, the first laminar flow 310 or the first stratified flow 331 can be diffused into a larger space in the first airway, which is convenient for the heat exchanger 500 or the heating core and other devices to process the gas; at the same time, the second laminar flow 320 or the second stratified flow 332 can be diffused into a larger space in the second airway, which is convenient for the heat exchanger 500 or the heating core and other devices to process the gas.

[0065] Please refer to Figure 2 and Figure 4 In some embodiments, the tip of the volute tongue 150 is formed as an auxiliary plane perpendicular to the partition 140, and the minimum distance between the auxiliary plane and the partition 140 is greater than or equal to 10 mm and less than or equal to 60 mm.

[0066] The volute tongue 150 is equivalent to the air outlet of the cross-flow fan 200. If the partition 140 is too close to the volute tongue 150, the wind speed is highest here, and the airflow may impact the partition 140 to generate turbulence; if the partition 140 is too far from the volute tongue 150, the movement direction of the outlet airflow of the cross-flow fan 200 may have deviated a lot from the circumferential direction of the eccentric vortex 201, and the deviation direction is uncertain (may change with the running state of the vehicle), so the airflow flow direction may not be along the plane where the partition 140 is located, but directly impact the partition 140 to generate turbulence.

[0067] When the minimum distance between the auxiliary plane and the partition 140 is greater than or equal to 10 mm and less than or equal to 60 mm, the distance between the partition 140 and the air outlet of the crossflow fan 200 is moderate, the gas velocity here is moderate, and it will not impact the side edge of the partition 140 to cause turbulence; the air flow also basically extends along the surface of the partition 140, and will not directly impact the side of the partition 140 to cause turbulence. Therefore, the partition 140 and the auxiliary plane are in the above range, which is conducive to maintaining laminar flow and improving the air supply capacity of the air conditioning box 1000.

[0068] Please refer to Figure 4 The auxiliary plane is the plane marked P in the figure. Figure 4In the illustrated embodiment, the minimum distance between the auxiliary plane and the partition 140 is D as shown in the figure.

[0069] In one example, the minimum distance between the auxiliary plane and the partition 140 can be 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm.

[0070] Please refer to Figure 3 and Figure 4 In some embodiments, the partition 140 is spaced apart from the housing 100 at one end away from the cross flow blower 200 to connect the first air duct 121 with the second air duct 122 .

[0071] The winds of the first wind channel 121 and the second wind channel 122 can merge in the housing 100, thereby meeting the need for a single wind outlet with a large amount of wind. Figure 3 The defrost vent 125 needs to have a large air volume to quickly defrost. When the driver's field of vision is restored, the airflow of the first air duct 121 and the airflow of the second air duct 122 can be combined and then sent out from the defrost vent 125. In another example, please refer to Figure 4 When the passenger compartment needs to be cooled quickly, the airflow of the first air duct 121 and the airflow of the second air duct 122 can be merged and blown out from the blowing air outlet 126, so as to quickly cool the passenger compartment.

[0072] Please refer to Figure 2 and Figure 4 In some embodiments, the air conditioning assembly includes a heat exchanger 500, which is disposed in the housing 100 and respectively separates the first air duct 121 and the second air duct 122; the heat exchanger 500 includes fins, and the fins are disposed parallel to the first laminar flow 310 and the second laminar flow 320 or the first stratified flow 331 and the second stratified flow 332.

[0073] In this way, the windward area of ​​the fins of the heat exchanger 500 is minimized, the obstruction to the airflow is minimized, and the air supply efficiency of the air conditioner 1000 can be improved. At the same time, since the gas will not accumulate at the heat exchanger 500, the heat exchanger 500 and the airflow can maintain a high temperature gradient, thereby improving the heat exchange efficiency.

[0074] The heat exchanger 500 can be an evaporator or a condenser. For an air conditioning assembly that can change the flow direction of the refrigerant, the heat exchanger 500 can be both an evaporator and a condenser, depending on the flow direction of the refrigerant.

[0075] Please refer to Figure 3 and Figure 4In some embodiments, the air conditioning assembly includes a warm air core 600, which is disposed in the shell 100. The warm air core 600 shields a portion of the first air duct 121 to form a first temperature air outlet 128. The air conditioning box 1000 includes a first temperature air door group 710, which is disposed in the shell 100, and is used to open the first temperature air outlet 128 and shield the warm air core 600 so that the first laminar flow 310 or the first stratified flow 331 bypasses the warm air core 600, or is used to close the first temperature air outlet 128 so that the first laminar flow 310 or the first stratified flow 331 passes through the warm air core 600.

[0076] In this way, the air conditioning assembly can control whether the first laminar flow 310 or the first stratified flow 331 flows through the warm air core 600; when heating is required, the first laminar flow 310 or the first stratified flow 331 flows through the warm air core 600 to meet the needs of the user; when heating is not required, the first laminar flow 310 or the first stratified flow 331 bypasses the warm air core 600 to reduce air flow resistance. Therefore, the above embodiment can improve the working efficiency of the air conditioning assembly.

[0077] Please refer to Figure 3 and Figure 4 In some embodiments, the warm air core 600 shields part of the second air duct 122 to form a second temperature air outlet 129, and the air conditioning box 1000 includes a second temperature air door group 720, which is arranged in the shell 100, and is used to open the second temperature air outlet 129 and shield the warm air core 600 so that the second laminar flow 320 or the second stratified flow 332 bypasses the warm air core 600, or is used to close the second temperature air outlet 129 so that the second laminar flow 320 or the second stratified flow 332 passes through the warm air core 600.

[0078] In this way, the air conditioning assembly can control whether the second laminar flow 320 or the second laminar flow 332 flows through the warm air core 600; when heating is required, the second laminar flow 320 or the second laminar flow 332 flows through the warm air core 600 to meet the needs of the user; when heating is not required, the second laminar flow 320 or the second laminar flow 332 bypasses the warm air core 600 to reduce air flow resistance. Therefore, the above embodiment can improve the working efficiency of the air conditioning assembly.

[0079] The damper of the first temperature damper group 710 is Figures 2 to 4 In the illustrated embodiment, a flag-shaped damper 920 is used. In other embodiments, the damper of the first temperature damper group 710 may also be a butterfly-shaped damper 910 or a barrel-shaped damper 930 .

[0080] The damper of the second temperature damper group 720 is Figures 2 to 4In the illustrated embodiment, a flag-shaped damper 920 is used. In other embodiments, the damper of the second temperature damper assembly 720 may also be a butterfly-shaped damper 910 or a barrel-shaped damper 930 .

[0081] Please refer to Figure 2 In some embodiments, the housing 100 is formed with a defrost air outlet 125 communicating with the first air duct 121 , a face-blowing air outlet 126 , and / or a foot-blowing air outlet 127 communicating with the second air duct 122 .

[0082] The defrost vent 125 can guide the gas in the housing 100 to the front windshield, rear windshield or window of the vehicle to defrost the glass and improve the driver's field of vision. The face vent 126 can deliver air to the upper body of the occupant and quickly adjust the air properties (temperature or humidity, etc.) at the upper body of the occupant. In addition, when the air delivered by the face vent 126 is cooling air, since the air outlet position of the face vent 126 is relatively high, the cold air can be delivered to the top of the passenger compartment, which helps to cool the entire passenger compartment. The foot vent 127 can deliver the airflow in the housing 100 to the lower body of the occupant and quickly change the air properties at the lower body of the occupant. In addition, when the air delivered by the foot vent 127 is heating air, since the air outlet position of the foot vent 127 is relatively low, the hot air can be delivered to the bottom of the passenger compartment, which helps to heat the entire passenger compartment.

[0083] Please refer to Figure 2 In some embodiments, the air conditioning box 1000 includes a defrost damper group 810 for opening or covering the defrost air outlet 125, a face damper group 820 for opening or covering the face air outlet 126, and / or a foot damper group 830 for opening or covering the foot air outlet 127.

[0084] In this way, the air conditioning assembly can adjust the switches of each air outlet, thereby improving the air conditioning assembly's ability to guide airflow.

[0085] exist Figure 2 The embodiment shown is in Figure 2 In the state shown, it can be seen that the defrost vents 125 are opened, the foot vents 127 are opened, and the face vents 126 are closed. At this time, if the first air inlet 111 allows outside air to enter, and the second air inlet 112 allows air in the passenger compartment to enter, it will help to use the dry air from the outside to defrost the glass inside the vehicle, and the air in the passenger compartment can be heated and sent out from the foot vents 127, thereby avoiding heat loss and improving the heating efficiency of the passenger compartment.

[0086] exist Figure 3 The embodiment shown is in Figure 3In the state shown, it can be seen that the defrost vent 125 is open, while the face vent 126 and the foot vent 127 are both closed. At this time, the airflow can first pass through the heat exchanger 500, and the heat exchanger 500 can work in the evaporator state, so that the airflow is cooled (equivalent to dehydration and drying), and then heated by the warm air core 600 (increasing the saturated vapor pressure), forming a dry and high-temperature airflow, and finally blown out from the defrost vent 125. When the ambient temperature is low, since the temperature inside the vehicle is higher than the temperature outside the vehicle, water droplets, i.e., fog water, may condense on the side of the vehicle glass facing the passenger compartment. The above-mentioned dry and high-temperature airflow can quickly evaporate the fog water and improve the defrosting efficiency.

[0087] exist Figure 3 The embodiment shown is in Figure 3 In the state shown, the heat exchanger 500 can work in the condenser state, so that the airflow is heated for the first time; the airflow passes through the warm air core 600 and is heated for the second time, forming a high-temperature airflow and blowing out from the defrost air outlet 125. The heat exchanger 500 can also not work, so that the airflow is only heated by the warm air core 600 to form a high-temperature airflow and blown out from the defrost air outlet 125. When the ambient temperature is low, solid particles, i.e., frost, may be condensed on the side of the vehicle glass facing the outside of the vehicle. The high-temperature airflow blown out from the defrost air outlet 125 can quickly heat the glass, so that the frost melts quickly, and improves the defrosting efficiency.

[0088] The dampers of the defrosting damper group 810, the dampers of the face-blowing damper group 820 and the dampers of the foot-blowing damper group 830 are Figure 2 In the illustrated embodiment, a flag-shaped damper 920 is used. In other embodiments, a butterfly-shaped damper 910 or a barrel-shaped damper 930 may also be used.

[0089] Please refer to Figure 2 and Fig.10 In some embodiments, a defrost air outlet 125 and a foot blowing air outlet 127 are formed on the housing 100, and the air conditioner 1000 further includes an air intake damper group 400, a defrost damper group 810, a foot blowing damper group 830, a heat exchanger 500, a warm air core 600 and a controller; the air intake damper group 400 is used to control the opening of the first air intake 111 and the second air intake 112; the defrost damper group 810 and the foot blowing damper group 830 are used to control the opening of the defrost air outlet 125 and the foot blowing air outlet 127 respectively; the heat exchanger 500 and the warm air core 600 are both arranged in the first air duct 121 and the second air duct 122; the heat exchanger 500 is arranged on the side of the warm air core 600 close to the cross flow fan 200; the controller is used to: When the ambient temperature is lower than a preset value, the air intake damper group 400 is controlled to open the first air intake port 111 and the second air intake port 112, and the defrost damper group 810 and the foot blowing damper group 830 are controlled to open the defrost air outlet 125 and the foot blowing air outlet 127 respectively, so that the first laminar flow 310 passes through the heat exchanger 500 and the heater core 600 and is blown out from the defrost air outlet 125, and at the same time, the second laminar flow 320 passes through the heat exchanger 500 and the heater core 600 and is blown out from the foot blowing air outlet 127.

[0090] When the ambient temperature is low, on the one hand, the moisture content of the air in the environment is low, which is very suitable for defrosting airflow to quickly evaporate the moisture on the glass; on the other hand, the passenger compartment needs to be heated. Therefore, the controller sets the air conditioning box 1000 to the above state, which is equivalent to Figure 2 The air conditioning box 1000 of the embodiment shown is arranged as follows Figure 2 It can be seen that at this time, the first laminar flow 310 and the second laminar flow 320 are blown out from the defrost damper and the foot blowing damper respectively, and the first air inlet 111 and the second air inlet 112 can be connected to the outside of the vehicle and the passenger compartment respectively, so that the cold air outside the vehicle can be used for rapid defrosting to improve the defrosting efficiency, and the hot air inside the vehicle and the cold air outside the vehicle can be prevented from mixing in the air-conditioning box 1000, resulting in excessive temperature drop in the vehicle, thereby improving the comfort of the passengers.

[0091] Please refer to Fig.10 , Fig.10 In the control method shown, the preset value is 10°C, so when the outside temperature is detected to be less than 10°C, the above control state can be entered. When the user presses the defrost and foot blowing buttons, it means that the user needs to defrost the windows and heat the car at the same time. Therefore, after receiving the user's command, the controller opens the first air inlet 111 and the second air inlet 112 by 50% each (that is, the opening ratio of the internal and external circulation dampers is 50%), and opens the defrost damper and the foot blowing damper, so that the outside air enters the cross-flow fan 200 through the first air inlet 111 (external circulation air inlet), and then blows out from the defrost vent 125 for defrosting; the internal air (the air in the passenger compartment) enters the cross-flow fan 200 through the second air inlet 112 (internal circulation air inlet), and then blows out from the foot blowing vent 127 to heat the passenger compartment.

[0092] In other embodiments, the preset value may be 0°C, 1°C, 2°C, 3°C, 4°C, 5°C, 6°C, 7°C, 8°C, 9°C, or 10°C.

[0093] Please refer to Figure 3 and Fig.11In some embodiments, when only the first air inlet 111 is opened, the crossflow fan 200 sucks air from the first air inlet 111 to form a total laminar flow 330 and blows it into the first air duct 121 to form a first laminar flow 331 and into the second air duct 122 to form a second laminar flow 332; the controller is further configured to: The air intake damper group 400 is controlled to open the first air intake port 111 and close the second air intake port 112, and the foot blowing damper group 830 is controlled to close the foot blowing damper, and the defrost damper group 810 is controlled to open the defrost damper, so that the first stratified flow 331 and the second stratified flow 332 pass through the heat exchanger 500 and the warm air core 600 and are blown out from the defrost air outlet 125.

[0094] In some application scenarios, the user may need a large air volume for defrosting, in which case the second air inlet 112 can be closed, leaving the first air inlet 111 fully open; the first air inlet 111 can be connected to the outside world, so that dry air from the outside can be used for defrosting, thereby improving defrosting efficiency.

[0095] When the first stratified flow 331 and the second stratified flow 332 pass through the heat exchanger 500, the heat exchanger 500 can be operated in the evaporator mode, so that the moisture in the gas of the first and second diversion layers can be condensed and removed; the first and second diversion layers from which moisture is removed are heated by the warm air core 600, so that the saturated vapor pressure in the first and second diversion layers is increased, and the fog on the glass can be removed more quickly. When the first stratified flow 331 and the second stratified flow 332 pass through the heat exchanger 500, the heat exchanger 500 can also be operated in the condenser mode or not operated, so that the first stratified flow 331 and the second stratified flow 332 are fully heated to quickly heat the glass and remove the frost on the glass.

[0096] Please refer to Fig.11 ,exist Fig.11 In the control method shown, when the user presses the defrost button, there may be no need to heat the passenger compartment, but high-power defrosting is required. At this time, the controller can control the first air inlet 111 to be fully opened (that is, the opening ratio of the internal and external circulation dampers is 100%), and open the defrost damper to allow the outside air to enter the cross-flow fan 200 through the first air inlet 111 (that is, the external circulation air inlet), and then blown out through the defrost air outlet 125 for defrosting.

[0097] Please refer to Figure 4 and Fig.12In some embodiments, when only the second air inlet 112 is opened, the crossflow fan 200 sucks air from the second air inlet 112 to form a total laminar flow 330, blows into the first air duct 121 to form a first stratified flow 331 and blows into the second air duct 122 to form a second stratified flow 332; a face-blowing air outlet 126 is also formed on the housing 100, and the air conditioning box 1000 also includes a face-blowing air door group 820 and a temperature air door group; the face-blowing air door group 820 is used to control the opening of the face-blowing air door; the temperature air door group is used to control whether the first stratified flow 331 and the second stratified flow 332 flow through the warm air core 600; the controller is also used to: The air intake damper group 400 is controlled to close the first air intake port 111 and open the second air intake port 112, and the defrost damper group 810 and the foot blowing damper group 830 are controlled to close the defrost damper and the foot blowing damper respectively, and the face blowing damper group 820 is controlled to open the face blowing damper. At the same time, the temperature damper group is controlled to allow the first stratified flow 331 and the second stratified flow 332 to bypass the warm air core 600, so that the first laminar flow 310 and the second laminar flow 320 are blown out from the face blowing port 126 after passing through the heat exchanger 500.

[0098] In some application scenarios, the user needs to quickly cool the passenger compartment. At this time, the first air inlet 111 is closed and the second air inlet 112 is opened; the first air inlet 111 can be connected to the outside, and the second air inlet 112 can be connected to the passenger compartment, so that hot air from the outside does not enter the vehicle. At the same time, the cross-flow fan 200 is completely used for the circulation of air in the passenger compartment to increase the circulation speed. At the same time, the first laminar flow 310 and the second laminar flow 320 are blown out from the blowing air outlet 126. At this time, the first laminar flow 310 and the second laminar flow 320 are cooled by the heat exchanger 500 and have a lower temperature, which can quickly reduce the temperature in the vehicle. Therefore, when the controller puts the air conditioner 1000 in the above state, the cooling efficiency can be improved.

[0099] Please refer to Fig.12 ,exist Fig.12 In the embodiment shown, when the user presses the blow button, it may be that the user wants to quickly cool the passenger compartment. At this time, the controller receives the instruction, closes the second air inlet 112 and opens the first air inlet 111 (that is, the opening ratio of the internal circulation damper is 0%), controls the temperature damper group to shield the warm air core 600 (this is for Figure 4 In the embodiment shown, the first temperature air door group 710 opens the first temperature air outlet 128 and shields the warm air core 600, and the second temperature air door group 720 opens the second temperature air outlet 129 and shields the warm air core 600, and corresponds to Fig.12 The upper temperature damper group and the lower temperature damper group are closed), and the surface damper is opened so that the internal air can enter the cross-flow fan 200 from the second air inlet 112 (internal circulation air inlet) and then be blown out from the surface damper 126, thereby quickly reducing the temperature of the passenger compartment.
