Detailed Implementation

[0032] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] As mentioned in the background section, in view of the problems in the prior art, this application proposes an energy-saving air conditioning device, such as... Figure 1 As shown, it includes: a draft mechanism, the draft mechanism comprising:

[0036] A ventilation duct housing 1, wherein the ventilation duct housing 1 has a first cavity 101 and a first connection port 111 communicating with the first cavity 101 is provided at the bottom of the ventilation duct housing 1; the side wall of the ventilation duct housing 1 is also provided with a first opening communicating with the first cavity 101; optionally, such as Figure 2 As shown, the air duct housing 1 is a cylindrical housing;

[0037] Impeller assembly 2, wherein the impeller assembly 2 is disposed within the first cavity 101 and is coaxial with the air duct housing 1; a second cavity is formed between the impeller assembly 2 and the air duct housing 1; a third cavity 202 is provided within the impeller assembly 2, and a second connection port 201 communicating with the third cavity 202 is provided at the bottom of the impeller assembly 2; the second connection port 201 is used to connect an external air inlet assembly 211; wherein, as shown Figure 3 As shown, the impeller assembly 2 is a cylindrical impeller. Multiple vertical openings are arranged in an array on the sidewall of the impeller assembly 2. The impeller assembly 2 is connected to a fourth drive motor, which drives the impeller assembly 2 to rotate. The rotation axis is oriented along the axis of the wind tunnel housing 1 and the impeller assembly 2. The external air inlet assembly 211 includes an external circulation air inlet, which is connected to the second connection port 201.

[0038] Adjustment component 3, which divides the first opening into a first air outlet 102 and a second air outlet 103, includes at least: a coaxially arranged annular first adjustment plate 302 and a second adjustment plate 301.

[0039] The first adjusting plate 302 is disposed in the second cavity;

[0040] A second adjusting plate 301 is disposed within the third cavity 202. The second adjusting plate 301 has a third connecting port 311 for connecting to an internal air intake assembly 312. A first ventilation duct 4 is provided between the third connecting port 311 and the internal air intake assembly 312. A first connecting assembly is provided on the first ventilation duct 4, and the end of the first connecting assembly away from the first ventilation duct 4 is connected to the first adjusting plate 302. The internal air intake assembly 312 includes an internal circulation air inlet, which is connected to the third connecting port 311.

[0041] Optionally, such as Figure 4 As shown, both the second adjusting plate 301 and the first adjusting plate 302 are annular air regulating plates. The first air outlet 102 is an internal circulation air outlet, and the second air outlet 103 is an external circulation air outlet. The first adjusting plate 302 is sleeved outside the impeller assembly 2, dividing the second cavity into upper and lower parts, a fourth and a fifth section. The second adjusting plate 301 is disposed inside the third cavity 202, dividing the third cavity 202 into upper and lower parts, a sixth and a seventh section. The sixth section, the fourth section, and the first air outlet 102 are interconnected, as are the seventh section, the fifth section, and the second air outlet 103.

[0042] Specifically, when the air conditioning system is turned on, outside air enters the seventh part through the external circulation air inlet, and inside air enters the sixth part through the internal circulation air inlet. The fourth drive motor drives the impeller assembly 2 to rotate, which can drive the air in the sixth part to the fourth part and out through the first air outlet 102, and drive the air in the seventh part to the fifth part and out through the second air outlet 103.

[0043] A first driving component is used to drive the adjusting component 3 to move within the first cavity 101 along a first direction; optionally, the first direction is the axial direction of the wind tunnel housing 1 and the impeller assembly 2, i.e., as shown in the figure. Figure 1 The vertical direction is shown; the first ventilation duct 4 is provided between the third connection port 311 and the internal air intake component 312, the first ventilation duct 4 is provided with the first connection component, and the end of the first connection component away from the first ventilation duct 4 is connected to the first adjusting plate 302. Therefore, the first driving component can drive the first adjusting plate 302 and the second adjusting plate 301 to move synchronously along the vertical direction.

[0044] Compared to the existing technology that uses a dual-impeller air intake to achieve dual-layer air intake, this solution can achieve dual-layer air intake by cooperating with the adjustment component 3 and a single impeller to complete the internal and external circulation separate air intake. By driving the adjustment component 3 to move along the first direction through the first drive component, the ratio of the air intake volume entering the first cavity 101 from the internal air intake component 312 and the external air intake component 211 can be adjusted according to the comfort of the passenger cabin, which simplifies the structure and is more energy-efficient.

[0045] Furthermore, a second ventilation duct 212 is provided between the second connection port 201 and the external air intake component 211, and a second opening is provided on the outer wall of the second ventilation duct 212; the end of the first ventilation duct 4 away from the third connection port 311 passes through the second opening and is connected to the internal air intake component 312, and the end of the first ventilation duct 4 near the third connection port 311 can extend and retract as the adjusting component 3 moves along the first direction; optionally, the first ventilation duct 4 is a corrugated pipe, and its end away from the third connection port 311 passes through the second opening, and the contact position with the second opening is welded to the second ventilation duct 212 to ensure that the... The sealing state inside the second ventilation duct 212 prevents air from outside the vehicle body from leaking out through the gap between the second opening and the first ventilation duct 4 when passing through the second ventilation duct 212. The extensibility of the corrugated pipe itself provides a guarantee for the vertical movement of the adjusting component 3. At the same time, the corrugations of the corrugated pipe are located at the end of the first ventilation duct 4 near the third connection port 311, which can ensure that when the adjusting component 3 moves vertically, the first ventilation duct 4 only expands or contracts at the end near the third connection port 311, thereby ensuring the stability of the connection between the end of the first ventilation duct 4 away from the third connection port 311 and the second ventilation duct 212.

[0046] Further, the first connecting component includes at least one first connecting member 5. One end of each first connecting member 5 is disposed on the outer wall of the first adjusting plate 302, and the end away from the first adjusting plate 302 is connected to the outer wall of the first ventilation duct 4. Optionally, there may be two first connecting members 5, which may be straight rods or arc-shaped pieces. One end of each first connecting member 5 is welded to the outer wall of the first air regulating component, and the end away from the first air regulating component is welded to the outer wall of the portion of the first ventilation duct 4 extending out of the second connecting port 201. The first connecting member 5 is an adjusting component bracket. When the second adjusting plate 301 is connected to the first ventilation duct 4 through the third connecting port 311, the first adjusting plate 302 is also connected to the first ventilation duct 4 through the adjusting component bracket. This ensures that when the first driving component drives the adjusting component 3 to move in the vertical direction, the second adjusting plate 301 and the first adjusting plate 302 always move synchronously, thereby ensuring independent air intake and independent air outlet for the internal and external circulation, and avoiding air mixing in the third cavity 202.

[0047] Further, the first drive assembly includes a first drive motor and a first gear connected to the main shaft of the first drive motor and mounted on the duct housing 1. A first rack 321 matching the first gear is provided on the outer wall of the first adjusting plate 302, and the first rack 321 extends in the first direction. The outer ring of the first gear has a ring of first meshing teeth, and the first rack 321 has a second meshing tooth meshing with the first meshing tooth. When the first drive motor rotates clockwise, it drives the first gear to rotate clockwise. At this time, the first rack 321, along with the rotation of the first gear, causes the first adjusting plate 302 and the second adjusting plate 301 to move upwards. As the second adjusting plate 301 moves upward, the internal circulation air intake of the sixth part gradually decreases, while the external circulation air intake of the seventh part gradually increases. When the first drive motor reverses, it drives the first gear to rotate counterclockwise. At this time, the first rack 321 moves the first adjusting plate 302 and the second adjusting plate 301 downward as the first gear rotates. As the first adjusting plate 302 and the second adjusting plate 301 move downward, the internal circulation air intake of the sixth part gradually increases, while the external circulation air intake of the seventh part gradually decreases. This allows for adjustment of the ratio of air intake from the internal circulation air intake and the external circulation air intake into the sixth and seventh parts according to the needs of the passenger cabin.

[0048] Furthermore, it also includes an evaporation mechanism 6, which is disposed on one side of the air intake mechanism along a second direction, the second direction being perpendicular to the first direction; the evaporation mechanism 6 includes a first air duct 601 and a second air duct 602 arranged along the first direction; the first air duct 601 is connected to the first air outlet 102, and the second air duct 602 is connected to the second air outlet 103; optionally, the second direction is... Figure 6 In the horizontal direction, the evaporation mechanism 6 is an evaporator; the internal circulation air entering the sixth part through the internal circulation air inlet flows to the fourth part with the rotation of the impeller assembly 2 and flows to the first air outlet 102 to the first air duct 601; the external circulation air entering the seventh part through the external circulation air inlet flows to the fifth part with the rotation of the impeller assembly 2 and flows to the second air outlet 103 to the second air duct 602; the air flowing into the first air duct 601 and the second air duct 602 is evaporated by the evaporator to form air with different temperatures and humidity.

[0049] Furthermore, it also includes a mixing mechanism, which is located on the side of the evaporation mechanism 6 away from the draft fan mechanism. The mixing mechanism includes:

[0050] The bellows housing 7 has a fourth cavity 701 inside, which has a first air inlet 702 connected to the first air duct 601 and a second air inlet 703 connected to the second air duct 602 near the evaporation mechanism 6; optionally, as Figure 6 As shown, the bellows housing 7 is a cylindrical housing;

[0051] A damper assembly is disposed within the fourth cavity 701 and rotatably connected to the bellows housing 7. The damper assembly divides the fourth cavity 701 into three parts: a first part 711, a second part 712, and a third part 713.

[0052] The second drive assembly drives the damper assembly to rotate, thereby changing the air intake volume of the first part 711, the second part 712, and the third part 713. Specifically, the first part 711 is where the internal circulation air entering the sixth part through the internal circulation air inlet flows to the fourth part as the impeller assembly 2 rotates, then flows out through the first air outlet 102 to the first air duct 601, and finally passes through the evaporator to form a low-temperature zone. The third part 713 is where the external circulation air entering the seventh part through the external circulation air inlet flows to the fourth part as the impeller assembly 2 rotates. The fifth part, after flowing out from the second air outlet 103 to the second air duct 602, forms a high-temperature zone after evaporation in the evaporator; the second part 712 is a medium-temperature zone formed by the mixing of air flowing out from the first air duct 601 and the second air duct 602; the second drive assembly controls the amount of air flowing out from the first air duct 601 and the second air duct 602 through the first air inlet 702 and the second air inlet 703 to each part of the first part 711, the second part 712 and the third part 713 by driving the damper assembly to rotate, thereby realizing the temperature regulation of the three temperature zones.

[0053] Furthermore, such as Figure 5 As shown, the damper assembly includes a first damper assembly 8 and a second damper assembly 9. The first damper assembly 8 includes a first rotating shaft 801 penetrating the bellows housing 7 along a third direction and a first damper 802 fixedly connected to the first rotating shaft 801. The second damper assembly 9 includes a second rotating shaft 901 penetrating the bellows housing 7 along the third direction and a second damper 902 fixedly connected to the second rotating shaft 901. The outer walls of both the first damper 802 and the second damper 902 are in contact with the inner wall of the bellows housing 7, and the third direction is perpendicular to the first direction. Both the first damper 802 and the second damper 902 are circular in shape, and the third direction is... Figure 1In the horizontal direction; specifically, the first damper 802 divides the first air inlet 702 into a third opening and a fourth opening, and the second damper 902 divides the second air inlet 703 into a fifth opening and a sixth opening. The third opening is connected to the first part 711, the fourth and fifth openings are connected to the second part 712, and the sixth opening is connected to the third part 713. The side of the air box housing 7 away from the evaporation mechanism 6 is provided with a third air outlet 704 connected to the first part 711, a fourth air outlet 705 connected to the second part 712, and a fifth air outlet 706 connected to the third part 713. The arrangement of the first damper assembly 8 and the second damper assembly 9 realizes synchronous three-temperature zone air outlet, and the air volume and air temperature of the three air outlets, the third air outlet 704, the fourth air outlet 705, and the fifth air outlet 706, can be changed by adjusting the angle of the first damper assembly 8 and the second damper assembly 9 according to different temperature requirements.

[0054] Furthermore, one end of the first rotating shaft 801 is provided with a second gear 803, and one end of the second rotating shaft 901 is provided with a third gear 903; the second drive assembly includes a second drive motor, the main shaft of the second drive motor is connected to the second gear 803, and is used to drive the second gear 803 to drive the first rotating shaft 801 and the first damper 802 to rotate; the second drive assembly also includes a third drive motor, the main shaft of the third drive motor is connected to the third gear 903, and is used to drive the third gear 903 to drive the second rotating shaft 901 and the second damper 902 to rotate;

[0055] Specifically, when the second drive motor drives the main shaft of the second drive motor to rotate clockwise, the second gear 803 rotates clockwise, causing the first rotating shaft 801 and the first damper 802 to rotate clockwise. The third opening gradually decreases, and the fourth opening gradually increases, thereby reducing the amount of air entering the first part 711 and increasing the amount of air exiting the first air duct 601 and entering the second part 712. When the second drive motor drives the main shaft of the second drive motor to rotate counterclockwise, the second gear 803 rotates counterclockwise, causing the first rotating shaft 801 and the first damper 802 to rotate counterclockwise. The third opening gradually increases, and the fourth opening gradually decreases, thereby increasing the amount of air entering the first part 711 and decreasing the amount of air exiting the first air duct 601 and entering the second part 712. When the third drive motor drives the main shaft of the third drive motor to rotate clockwise, the third gear 803 rotates clockwise. When the needle rotates, it drives the second rotating shaft 901 and the second air damper 902 to rotate clockwise. The sixth opening gradually enlarges, and the fifth opening gradually shrinks, thereby increasing the amount of air entering the third part 713 and decreasing the amount of air exiting the second air duct 602 and entering the second part 712. When the third drive motor drives the main shaft of the third drive motor to rotate in reverse, the third gear 903 rotates counterclockwise, driving the second rotating shaft 901 and the second air damper 902 to rotate counterclockwise. The sixth opening gradually shrinks, and the fifth opening gradually enlarges, thereby decreasing the amount of air entering the third part 713 and increasing the amount of air exiting the second air duct 602 and entering the second part 712. Therefore, by driving the first air damper assembly 8 and the second air damper assembly 9 to rotate through the second drive motor and the third drive motor, the air volume and temperature of each air outlet can be adjusted according to the different temperature requirements of the passenger compartment.

[0056] Furthermore, a sealing element is provided between the outer wall of the impeller assembly 2 and the second adjusting plate 301. The outer ring of the sealing element is fixedly connected to the inner ring of the second adjusting plate 301, and the inner ring of the sealing element is a smooth surface that contacts the outer wall of the impeller assembly 2. Optionally, the sealing element can be a rubber ring, which can be bonded to the inner ring of the second adjusting plate 301. The contact surface between the impeller assembly 2 and the rubber ring is a smooth surface, reducing the resistance when the impeller assembly 2 rotates.

[0057] Example 2

[0058] Based on Embodiment 1, this application further proposes a vehicle including the aforementioned energy-saving air conditioning device. Specifically, when passengers ride in the vehicle, they can set the target air conditioning temperature according to their own needs. External air enters the seventh part through the external circulation air inlet, and internal air enters the sixth part through the internal circulation air inlet. The fourth drive motor drives the impeller assembly 2 to rotate. The rotation of the impeller assembly 2 can drive the air entering the sixth part to flow to the fourth part and out through the first air outlet 102, and drive the air entering the seventh part to flow to the fifth part and out through the second air outlet 103. Furthermore, the first drive assembly drives the adjustment assembly 3 to move up and down, which can adjust the ratio of the air intake from the internal circulation air inlet and the external circulation air inlet to the sixth and seventh parts according to the comfort of the passenger compartment. After passing through the fourth part, the first air outlet 102, and the first air duct 601, part of the air flows to the first part 711, and part flows to the second part 712. After entering the seventh part, the air flows through the fifth part, the second air outlet 103, and the second air duct 602, part flows into the second part 712, and part flows to the third part 713. The second drive assembly drives the damper assembly to rotate, thereby adjusting the air intake volume of the first part 711 and the third part 713, as well as the air mixing ratio of the second part 712, to meet the comfort of the passenger compartment and ensure that the glass does not fog up in winter. The adjustment ratio is related to the comfort of the air conditioning, energy consumption, and the intake air temperature of the internal and external circulation. The intake air temperature of the internal and external circulation can be adjusted according to the adjustment of the internal and external circulation intake air ratio, which can reduce the heat load of the condenser and the power of the compressor, thereby achieving energy saving of the air conditioning unit.
