[0002] Currently, most automotive air conditioners adopt a direct air outlet method, and the air outlet is mostly directed through the grille blades of the air outlet. This method can only concentrate the air outlet in one direction. When the air conditioner is just started, it has the advantages of large air volume, high wind speed, blowing directly at passengers, and being able to quickly cool down. However, after the vehicle interior temperature reaches the temperature required by the passengers, during the normal temperature maintenance process, the air outlet still concentrates in one direction and continues to blow directly at the passengers. The cold air blows directly on the human body, causing a cold feeling in the place where the passengers are blown, while other places are still relatively hot, and the vehicle interior temperature is unevenly distributed, affecting the comfort experience. Especially for vulnerable groups such as children and the elderly, it is easy to cause problems such as colds. Summary of the Invention

[0034] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0035] The embodiments of the present application provide a draft-free air supply system and method for an automotive air conditioner, which can solve the problem in the related art that the air blown out by the automotive air conditioner directly blows on the human body, affecting the comfort experience.

[0036] Currently, most automotive air conditioners adopt the direct air supply method, and the air supply is mostly guided through the grille blades of the air outlet. This method can only concentrate the air supply in one direction. For the air conditioner at the beginning of startup, it has the advantages of large air volume, fast wind speed, blowing on the passengers, and being able to quickly cool down. However, after the temperature inside the vehicle reaches the temperature required by the passengers, during the normal temperature maintenance process, the air supply still concentrates in one air direction and continues to blow on the passengers. The cold air directly blows on the human body, causing a cold feeling in the place where the passengers are blown, while other places are still relatively hot, and the temperature inside the vehicle is unevenly distributed, affecting the comfort experience. Especially for vulnerable groups such as children and the elderly, it is easy to cause problems such as colds.

[0037] In view of the problem in the related art that the air output of the automotive air conditioner blows directly on the human body, affecting the comfort experience, the present application provides a draft-free air output system and method for an automotive air conditioner, which can not only output air through a conventional air outlet, but also be adjusted to draft-free air output. A plurality of air outlet holes 3 are evenly arranged on the front draft-free air duct and the rear draft-free air duct 221. The plurality of air outlet holes 3 disperse the air flow into fine air flows, turning strong wind into gentle wind, avoiding strong wind from blowing directly on the human body, and the human body will not feel obvious wind sensation, thereby improving the comfort of users.

[0038] See Figures 1 to 8 In a first aspect, an embodiment of the present application provides a draft-free air output system for an automotive air conditioner, which includes: a front air conditioning air supply component 1, a rear air conditioning air supply component 2, and a controller. The front air conditioning air supply component 1 includes a front air conditioning box body 10, a front conventional air outlet 11, and a front draft-free air duct. The front conventional air outlet 11 and the front draft-free air duct are selectively communicated with the front air conditioning box body 10; the rear air conditioning air supply component 2 includes a rear air conditioning box body 20, a rear conventional air duct 220, and a rear draft-free air duct 221. The rear conventional air duct 220 and the rear draft-free air duct 221 are selectively communicated with the rear air conditioning box body 20; the controller is connected to the front air conditioning box body 10 and the rear air conditioning box body 20; wherein, a plurality of air outlet holes 3 are evenly arranged on the front draft-free air duct and the rear draft-free air duct 221.

[0039] Wherein, the controller is connected to the front air conditioning air supply component 1 and the rear air conditioning air supply component 2 through signal lines to ensure accurate and efficient signal transmission, and ensure that the air conditioning system can be accurately adjusted according to the needs of passengers.

[0040] A front conventional air outlet 11 and a front draft-free air duct are provided in the front air conditioning air supply component 1. In this embodiment, the front conventional air outlet 11 is as Figure 2 shown, including the instrument panel blowing air ducts and air outlets for supplying air to the front air conditioning box body 10 in the conventional four, which can output conventional air to the front row passengers; the front draft-free air duct is arranged at the position of the whole vehicle roof, and a plurality of micro air outlet holes 3 are distributed thereon to provide draft-free air output to the front row passengers.

[0041] A rear conventional air duct 220 and a rear draft-free air duct 221 are provided in the rear air conditioning air supply component 2. Different from the front air conditioning air supply component 1, both the rear conventional air duct 220 and the rear draft-free air duct 221 are arranged at the position of the whole vehicle roof. After the rear conventional air duct 220 is supplied with air by the rear air conditioning box body 20, it outputs conventional air to the rear row passengers. A plurality of micro air outlet holes 3 are distributed on the rear draft-free air duct 221 to provide draft-free air output to the rear row passengers.

[0042] At the same time, see Figure 2In the structure within the shown square frame, the front windless air duct and the rear windless air duct 221 form a ceiling air duct that covers the entire ceiling. It should also be noted that the front windless air duct equipped with the front air-conditioning air supply component 1 and the rear windless air duct 221 equipped with the rear air-conditioning air supply component 2 are independent of each other in design and are not connected; such a design ensures that the front and rear seat passengers can independently adjust the air-conditioning air supply modes in their respective areas. The front seat passengers can choose the windless mode, and the rear seat passengers can also adjust the air supply intensity according to their preferences, without interference from each other, providing a more personalized and comfortable riding environment for the passengers in the vehicle.

[0043] Based on the above embodiments, in this embodiment, the front windless air duct includes: a first air duct 12, a second air duct 13, a third air duct 14, and a first ceiling air duct 15.

[0044] Among them, the first air duct 12 is used to be arranged inside the vehicle instrument panel; the second air duct 13 is connected to the first air duct 12 and is used to be arranged inside the vehicle body floor; the third air duct 14 is connected to the second air duct 13 and is used to be arranged inside the vehicle body B-pillar; the first ceiling air duct 15 is connected to the third air duct 14 and is used to be arranged at the vehicle body ceiling, and the air outlet holes 3 are opened on the first ceiling air duct 15.

[0045] Specifically, the first air duct 12 is connected to the front air-conditioning box body 10 and passes through the sub-instrument panel in the whole vehicle. The second air duct 13 passes through the vehicle body floor in the whole vehicle. The third air duct 14 passes through the vehicle body B-pillar. The first ceiling air duct 15 is arranged at the vehicle body ceiling. When the front air-conditioning box body 10 supplies air, if the windless mode is selected, the air-conditioning air passes through the first air duct 12, the second air duct 13, and the third air duct 14 and then reaches the first ceiling air duct 15, and then is blown out through the air outlet holes 3 of the first ceiling air duct 15.

[0046] In the windless air outlet system, the controller can control the front air-conditioning box body 10 to supply air to the front conventional air outlet 11, that is, the conventional instrument panel air outlet duct and air outlet, during the rapid cooling stage. The air outlet damper area of this air outlet is large and the air speed is high, and the air speed ≥ 6m / s, which can achieve rapid cooling; after the vehicle interior temperature reaches the temperature required by the passengers, during the normal temperature maintenance process, the controller can control the front air-conditioning box body 10 to supply air to the front windless air duct to achieve windless air outlet.

[0047] Based on the above embodiments, in this embodiment, the rear air-conditioning air supply component 2 further includes a second ceiling air duct 22. A partition is arranged inside the second ceiling air duct 22 to divide the interior of the second ceiling air duct 22 into a rear conventional air duct 220 and a rear windless air duct 221, and the air outlet holes 3 are opened on the rear windless air duct 221.

[0048] In this embodiment, the rear conventional air duct 220 and the rear draft-free air duct 221 are both arranged at the vehicle roof. To simplify the air duct design and avoid excessive structural complexity and tediousness, the rear conventional air duct 220 and the rear draft-free air duct 221 are specially arranged to ensure that while meeting the functional requirements, the vehicle can also maintain simplicity and efficiency: the rear conventional air duct 220 and the rear draft-free air duct 221 are integrated to form the second roof air duct 22, and a partition is arranged in the second roof air duct 22 to divide its interior into the rear conventional air duct 220 and the rear draft-free air duct 221; by arranging the partition, the rear conventional air duct 220 and the rear draft-free air duct 221 are independent of each other and do not interfere with each other.

[0049] Among them, there are various ways to arrange the partition. In some embodiments, the partition is arranged horizontally to divide the interior of the second roof air duct 22 into the rear conventional air duct 220 and the rear draft-free air duct 221 arranged vertically one above the other; in other embodiments, as shown in Figure 3 and Figure 4 , the partition is arranged vertically to divide the interior of the second roof air duct 22 into the rear conventional air duct 220 and the rear draft-free air duct 221 arranged on both sides. In this embodiment, it is also necessary to ensure that both the rear conventional air duct 220 and the rear draft-free air duct 221 are arranged along the vehicle body length direction.

[0050] Therefore, a fourth air duct 21 is arranged on the second roof air duct 22. The fourth air duct 21 is arranged at the vehicle body side wall, and the fourth air duct 21 is arranged to communicate with the rear air-conditioning box 20. When the controller controls the rear air-conditioning box 20, the air sent out by the rear air-conditioning box 20 climbs through the fourth air duct 21 at the side wall to the second roof air duct 22 located on the vehicle roof.

[0051] Furthermore, since the interior of the second roof air duct 22 is separated by a partition and the air sent by the fourth air duct 21 directly reaches the interior of the second roof air duct 22, in order to divide the conventional air supply and draft-free air supply, a air distribution structure 23 is arranged between the rear conventional air duct 220 and the rear draft-free air duct 221.

[0052] Among them, the air distribution structure 23 has a first state and a second state. When in the first state, the rear conventional air duct 220 is opened and the rear draft-free air duct 221 is closed. When in the second state, the rear conventional air duct 220 is closed and the rear draft-free air duct 221 is opened.

[0053] The air distribution structure 23 includes: a damper motor 230, an adjustment mode disc 231, a first lever 234, a first damper 232, a second lever 235 and a second damper 233. The adjustment mode disc 231 is fixed to the output shaft of the damper motor 230 and is rotatably connected to the second ceiling air duct 22. The first lever 234 is connected to the adjustment mode disc 231. The first damper 232 is connected to the first lever 234 and is located inside the rear conventional air duct 220. The second lever 235 is connected to the adjustment mode disc 231. The second damper 233 is connected to the second lever 235 and is located inside the rear draft-free air duct 221.

[0054] See Figure 4 and Figure 5 As shown, some components in the air distribution structure 23 are arranged at the top of the second ceiling air duct 22, and some other components are arranged inside the second ceiling air duct 22. Specifically, the damper motor 230 and the adjustment mode disc 231 are installed at the top of the second ceiling air duct 22. The adjustment mode disc 231 is a cam structure. The output shaft of the damper motor 230 is fixedly connected to the adjustment mode disc 231. When the damper motor 230 works, it can drive the adjustment mode disc 231 to rotate. Both the first lever 234 and the second lever 235 are provided with drive shafts connected to the adjustment mode disc 231. The first damper 232 is connected to the first lever 234 through a damper drive shaft, and the second damper 233 is connected to the second lever 235 through a damper drive shaft. The air inlet of the rear conventional air duct 220 is horizontally installed with the first damper 232 in the middle, and the air inlet of the rear draft-free air duct 221 is horizontally installed with the second damper 233 in the middle. The damper drive shaft of the first damper 232 is driven by the first lever 234, and the damper drive shaft of the second damper 233 is driven by the second lever 235.

[0055] See Figure 8 As shown, the rear conventional air duct 220 is provided with ceiling air outlets 24. In this embodiment, there are four ceiling air outlets 24. It should be noted that in this application, the setting of the number of ceiling air outlets 24 is not limited. The damper motor 230 adjusts the opening and closing of the first damper 232 and the second damper 233 by driving the adjustment mode disc 231, the first lever 234 and the second lever 235: when the first damper 232 is opened and the second damper 233 is closed, the rear conventional air duct 220 is opened and the rear draft-free air duct 221 is closed. The 4 ceiling air outlets 24 of the rear conventional air duct 220 blow air; when the first damper 232 is closed and the second damper 233 is opened, the micro air outlet holes 3 of the rear draft-free air duct 221 blow air.

[0056] That is to say, the second ceiling air duct 22 is supplied with air by the rear air-conditioning box body 20. The second ceiling air duct 22 is divided into two branches at the position where the vehicle body side wall leads to the vehicle ceiling: the rear conventional air duct 220 and the rear draft-free air duct 221. At the air inlets of the rear conventional air duct 220 and the rear draft-free air duct 221 on the main road, a wind distribution structure 23 is arranged, which can choose to guide the air to the rear conventional air duct 220 or the rear draft-free air duct 221.

[0057] Furthermore, a relay blower 25 is arranged in the rear draft-free air duct 221. In this embodiment, two relay blowers 25 are arranged to evenly send the air that climbs from the fourth air duct 21 to the second ceiling air duct 22 by the rear air-conditioning box body 20 to the micro air outlets 3 of the rear draft-free air duct 221, reducing the wind resistance, making the air outlet more uniform and quieter, enabling a static pressure chamber to be formed after the cold air enters the rear draft-free air duct 221. The pressure in the static pressure chamber is higher than the vehicle interior pressure, so that the cold air flows out of the micro ventilation opening at a lower flow rate to form a draft-free air outlet. The air temperature of the cold air is lower than the air temperature in other areas of the vehicle interior, and it will gradually sink and mix with the vehicle interior air to offset the external light and other heat effects, maintaining the vehicle interior temperature from rising and maintaining at the temperature required by the passengers. In this embodiment, the relay blower 25 selects a blower with a relatively small power, and the power is between 60W and 100W.

[0058] The controller can control the rear air-conditioning box body 20 to supply air to the 4 ceiling air outlets 24 of the rear conventional air duct 220 of the second ceiling air duct 22 during the rapid cooling stage, and supply air to the rear draft-free air duct 221 of the second ceiling air duct 22 during the normal temperature maintenance process after the vehicle interior temperature reaches the temperature required by the passengers, realizing draft-free air outlet.

[0059] Furthermore, a guiding structure 2210 is arranged in the ceiling air duct, that is, the guiding structure 2210 is arranged on the inner walls of the first ceiling air duct 15 and the rear draft-free air duct 221. The guiding structure 2210 includes multiple guiding and wind distribution ribs, which are determined with the goal of making the air speeds of the respective micro air outlets 3 uniform, that is, aiming to ensure that the air speeds of the respective micro air outlets 3 can reach the goal of being uniform and consistent through the air flow distribution principle. Through reasonable layout, the stable guiding and uniform distribution of the air flow in the first ceiling air duct 15 and the rear draft-free air duct 221 are realized.

[0060] Based on the above embodiments, in this embodiment, a plurality of micro air outlets 3 communicating with the passenger compartment are arranged on both the first ceiling air duct 15 and the rear draft-free air duct 221. The size and arrangement of the air outlets 3 are determined with the goal of making the air velocity in the static pressure chamber ≤ 2 m / s. Along the axis of the air outlet 3, and from the air inlet side to the air outlet side of the air outlet 3, the diameter of the air outlet 3 gradually decreases. The micro holes are circular holes, and two adjacent air outlets 3 on the air inlet side of the air outlet 3 are tangent to each other, so that the micro holes on the air inlet side are as large as possible and the air intake is smooth.

[0061] Based on the above embodiments, in this embodiment, a manual button for switching between the draft-free mode and the normal mode is arranged on the whole vehicle, and the air outlet mode can be manually switched by a person.

[0062] When the normal mode is selected, the controller controls the front air-conditioning box 10 to supply air to the front normal air outlet 11, controls the rear air-conditioning box 20 to supply air, and after the air reaches the second ceiling air duct 22, controls the damper motor 230 of the air distribution structure 23 to drive and adjust the mode disk 231, drives the first damper 232 to open through the first lever 234, drives the second damper 233 to close through the second lever 235, and the air supplied by the rear air-conditioning box 20 exits from the normal ceiling air outlet 24 of the rear normal air duct 220.

[0063] When the draft-free air outlet mode is selected, the controller controls the air supply of the front air-conditioning box 10 to pass through the first air duct 12, the second air duct 13, and the third air duct 14 located on the lower instrument panel and reach the first ceiling air duct 15 located on the vehicle body ceiling. Controls the rear air-conditioning box 20 to supply air to the rear draft-free air duct 221 located in the second ceiling air duct 22, controls the damper motor 230 of the air distribution structure 23 to control and adjust the mode disk 231, drives the first damper 232 to close through the first lever 234, drives the second damper 233 to open through the second lever 235, and the air supplied by the rear air-conditioning box 20 enters the rear draft-free air duct 221.

[0064] Based on the above embodiments, in this embodiment, the draft-free air outlet system further includes an outside temperature sensor, a front row in-vehicle temperature sensor, a rear row in-vehicle temperature sensor, a sunlight sensor, and an outside temperature sensor that are signal-connected to the controller. The outside temperature sensor, the front row in-vehicle temperature sensor, the rear row in-vehicle temperature sensor, the sunlight sensor, and the outside temperature sensor are all used to detect the current environmental parameters, so that the controller can adjust the operating gear of the blowers of the front air-conditioning box 10 and the rear air-conditioning box 20, the compressor speed, the opening degree of the electronic expansion valve, etc. according to the current environmental parameters and the target temperature set by the passengers, to adjust the air outlet temperature and the air outlet volume.

[0065] In addition, when receiving the instruction to turn on the windless air supply mode, obtain the target temperature set by the passenger, the operating parameters of the front in-vehicle temperature sensor, the operating parameters of the rear in-vehicle temperature sensor, the operating parameters of the sunlight sensor, and the out-of-vehicle ambient temperature. Determine whether there is one item among the target temperature set by the passenger, the out-of-vehicle ambient temperature, and the light intensity that does not meet the corresponding preset conditions. If there is one item that does not meet the corresponding preset conditions, enter the windless air supply mode and send a windless air supply signal to the controller. Among them, the preset conditions include that the difference between the target temperature set by the passenger and the front in-vehicle temperature is within the first set range, the difference between the in-vehicle ambient temperature and the out-of-vehicle ambient temperature is within the second set range, the light intensity is within the third set range, and the difference between the target temperature set by the passenger and the rear in-vehicle temperature is within the fourth set range.

[0066] If receiving the windless air supply signal, control the damper to rotate through the air distribution structure 23, turn on the micro windless air supply signal, and arrange all the air supply gears from high to low. There are also multiple windless air supply gears during windless air supply. Each windless air supply gear corresponds to a downshift preset temperature range and an upshift preset temperature range. Any temperature in the down / upshift preset temperature range corresponding to the relatively high gear is greater than any temperature in the down / upshift preset temperature range corresponding to the relatively low gear. For the same windless air supply gear, the upper / lower limit temperature of the downshift preset temperature range is less than the upper / lower limit temperature of the upshift preset temperature range.

[0067] When the controller in the windless air supply system determines that the continuous operation duration of the current windless air supply gear reaches the corresponding preset duration, detect whether the front in-vehicle temperature and the front in-vehicle temperature drop to within a downshift preset temperature range corresponding to the current windless air supply gear through the above sensors. If so, continue to operate at this windless air supply gear. Otherwise, change the air supply temperature and the air volume gear by adjusting the duty cycle information of the relay blower 25, the blower of the front air-conditioning box 10, and the blower of the rear air-conditioning box 20, and by adjusting the compressor speed and the opening degree of the electronic expansion valve.

[0068] In summary, in the windless air supply system of the present application, it can supply air through the conventional air outlets during the cooling or heating stage, and can also be adjusted to windless air supply during the normal temperature maintenance process after the in-vehicle temperature reaches the temperature required by the passenger. The multiple air outlet holes 3 disperse the air flow into fine air currents, turning the strong wind into a gentle wind, avoiding the strong wind blowing directly on the human body, and the human body will not feel an obvious sense of wind, thereby improving the comfort of the user. And it can achieve full-range windless air supply, with gentle wind emitted from the top windless air outlets at all positions in the front row, middle row, and rear row of the whole vehicle, covering all positions of the whole vehicle.

[0069] In a second aspect, an embodiment of the present application provides a method for windless air supply of an automotive air conditioner, which includes:

[0070] When the controller receives a normal air outlet signal, it controls the front air-conditioning box 10 to blow air through the front normal air outlet 11, and the rear air-conditioning box 20 to blow air through the rear normal air duct 220;

[0071] When the controller receives a draft-free air outlet signal, it controls the front air-conditioning box 10 to blow air through the front draft-free air duct, and the rear air-conditioning box 20 to blow air through the rear draft-free air duct 221.

[0072] In this application, the above draft-free air outlet system is used to implement the draft-free air outlet method.

[0073] When the normal mode is selected, that is, when the controller receives a normal air outlet signal, the controller controls the front air-conditioning box 10 to supply air to the front normal air outlet 11. After controlling the rear air-conditioning box 20 to supply air and reach the second ceiling air duct 22, the controller controls the damper motor 230 of the air distribution structure 23 to drive the adjustment mode disc 231, drives the first damper 232 to open through the first lever 234, drives the second damper 233 to close through the second lever 235, and the air supply from the rear air-conditioning box 20 exits through the normal ceiling air outlet 24 of the rear normal air duct 220.

[0074] When the draft-free air outlet mode is selected, that is, when the controller receives a draft-free air outlet signal, the controller controls the front air-conditioning box 10 to supply air through the first air duct 12, the second air duct 13, and the third air duct 14 located on the passenger's dashboard and reach the first ceiling air duct 15 located on the vehicle body ceiling. The controller controls the rear air-conditioning box 20 to supply air to the rear draft-free air duct 221 located in the second ceiling air duct 22, controls the damper motor 230 of the air distribution structure 23 to control the adjustment mode disc 231, drives the first damper 232 to close through the first lever 234, drives the second damper 233 to open through the second lever 235, and the air supply from the rear air-conditioning box 20 enters the rear draft-free air duct 221.

[0075] Further, when the controller receives a normal air outlet signal, after controlling the front air-conditioning box 10 to blow air through the front normal air outlet 11 and the rear air-conditioning box 20 to blow air through the rear normal air duct 220, if the temperature inside the vehicle is lower than the set temperature, the controller controls the front air-conditioning box 10 to blow air through the front draft-free air duct and the rear air-conditioning box 20 to blow air through the rear draft-free air duct 221.

[0076] Specifically, the controller can control the front air-conditioning box 10 to supply air to the front normal air outlet 11, that is, the normal dashboard air-blowing duct and air outlet during the rapid cooling stage. The air-blowing outlet damper has a large area and a high wind speed, with a wind speed ≥ 6 m / s, which can achieve rapid cooling. After the temperature inside the vehicle reaches the temperature required by the passengers, during the normal temperature maintenance process, the controller can control the front air-conditioning box 10 to supply air to the front draft-free air duct to achieve draft-free air outlet.

[0077] The controller can control the rear air-conditioning box body 20 to supply air to the 4 ceiling air outlets 24 of the rear conventional air duct 220 of the second ceiling air duct 22 during the rapid cooling stage. After the vehicle interior temperature reaches the temperature required by the passengers, during the normal temperature maintenance process, it supplies air to the rear draft-free air duct 221 of the second ceiling air duct 22 to achieve draft-free air supply.
