[0048] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0049] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0050] The fresh air component 100 according to the first aspect of the utility model is described below with reference to the accompanying drawings.

[0051] According to some embodiments of the present invention, the fresh air component 100 is as follows: Figure 1 and Figure 2 As shown, it includes: a fresh air shell 1, a fresh air fan 2, a fresh air valve 3 and a valve device 4. A fresh air duct 11 is formed in the fresh air shell 1. A fresh air outlet 12 and an indoor air inlet 13 connected to the fresh air duct 11 are formed on the fresh air shell 1. The fresh air outlet 12 is connected to the outdoor side, and the indoor air inlet 13 is connected to the indoor side. The fresh air fan 2 is arranged in the fresh air duct 11.

[0052] The fresh air housing 1 is an outer contour part of the fresh air component 100 . A fresh air duct 11 is defined in the fresh air housing 1 . The fresh air housing 1 has two air inlets, a fresh air port 12 and an indoor air inlet 13 .

[0053] Outdoor fresh air flows into the fresh air duct 11 from the fresh air outlet 12 and then flows into the room, which can transport fresh air to the room, improve the indoor air quality, and increase fresh air and remove pollutants.

[0054] Indoor air flows into the fresh air duct 11 from the indoor air inlet 13 and then flows into the room, which can circulate the indoor air flow and increase the indoor air flow. Optionally, a filter is provided in the fresh air component 100, which filters the air flow, thereby purifying the indoor air and improving the indoor air quality.

[0055] A fresh air valve 3 is provided at the fresh air outlet 12, and the fresh air valve 3 is used to open and close the fresh air outlet 12; the valve device 4 includes a driver 4a and a valve 4b, the valve 4b is provided at the indoor air inlet 13, and the driver 4a is connected to the valve 4b to drive the valve 4b to open and close the indoor air inlet 13.

[0056] A fresh air valve 3 is provided at the fresh air outlet 12, and a valve 4b is also provided at the indoor air inlet 13. The fresh air valve 3 and the valve 4b are controlled independently of each other, and the fresh air component 100 can transport fresh air to the room and the fresh air component 100 can circulate the indoor air and can work independently of each other to reduce interference; the fresh air component 100 can transport fresh air to the room and the fresh air component 100 can circulate the indoor air and can also cooperate with each other to meet different air supply needs and improve the functionality of the fresh air component 100.

[0057] For example, in the cold winter, the temperature of the outdoor air is low, and the temperature difference between the indoor and outdoor is large. If the outdoor fresh air is directly delivered to the indoor, the temperature at the outlet will drop sharply, and the indoor temperature difference will be large, causing discomfort to the human body, and it may also damage the internal components of the fresh air component 100, reducing the service life of the fresh air component 100. However, by the cooperation between the fresh air outlet 12 and the indoor air inlet 13, the indoor air is mixed with the outdoor air intake and delivered to the indoor, which can reduce the temperature difference between the airflow delivered to the indoor and the indoor temperature, gently deliver fresh air to the indoor, and improve the air supply effect. It can also improve the damage of the low-temperature airflow to the internal components of the fresh air component 100, and extend the service life of the fresh air component 100.

[0058] According to the fresh air component 100 of the embodiment of the utility model, a fresh air valve 3 is provided at the fresh air outlet 12, and a valve 4b is also provided at the indoor air inlet 13. The fresh air component 100 can transport fresh air to the room and the fresh air component 100 can circulate the indoor air and can work independently or in coordination with each other, thereby meeting different air supply needs and improving the functionality of the fresh air component 100.

[0059] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the fresh air housing 1 includes a fresh air inlet frame 1a, and a fresh air port 12 and an indoor air inlet 13 are both formed on the fresh air inlet frame 1a.

[0060] In some embodiments of the present invention, Figure 1 As shown, a fresh air outlet 14 communicating with the fresh air duct 11 is also formed on the fresh air housing 1 .

[0061] The outdoor fresh air flows into the fresh air duct 11 from the fresh air inlet 12, and then flows into the room through the fresh air outlet 14, which can deliver fresh air to the room, improve the indoor air quality, and increase fresh air removal. Figure 1 As shown, the indoor air flows into the fresh air duct 11 from the indoor air inlet 13, and then flows into the room through the fresh air outlet 14, which can circulate the indoor air flow and increase the indoor air flow. The dotted line with an arrow in the figure is the airflow direction.

[0062] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the edge of the indoor air inlet 13 has a first retaining edge 131 and a second retaining edge 132 that are arranged opposite to and in the same plane.

[0063] The first baffle edge 131 and the second baffle edge 132 participate in defining the indoor wind inlet 13. It is worth noting that the first baffle edge 131 and the second baffle edge 132 are not limited to being flat plates, but can also be two parts surrounding the indoor wind inlet 13. The first baffle edge 131 and the second baffle edge 132 are relatively arranged in a preset direction.

[0064] For example, the indoor air inlet 13 is a circular hole, and the first stop edge 131 and the second stop edge 132 are arranged opposite to each other in the radial direction. Optionally, the first stop edge 131 and the second stop edge 132 may be partial arc portions that participate in defining the circular hole; or, further optionally, the first stop edge 131 and the second stop edge 132 both participate in defining a semicircle of the circular hole, and the first stop edge 131 and the second stop edge 132 jointly define the indoor air inlet 13.

[0065] For example, the indoor air inlet 13 is a rectangular hole, and the first baffle 131 and the second baffle 132 are disposed in opposite directions of the rectangular hole. Optionally, the first baffle 131 and the second baffle 132 may participate in defining one side of the rectangular hole; or, alternatively, the first baffle 131 and the second baffle 132 are both semi-enclosed, and the first baffle 131 and the second baffle 132 jointly define the indoor air inlet 13.

[0066] like Figure 2 As shown, the valve 4b includes: a rotating shaft 41 and a valve plate 42, and the rotating shaft 41 is connected to the driver 4a so as to drive the rotating shaft 41 to rotate through the driver 4a. The valve plate 42 is rotatably arranged at the indoor air inlet 13 to open and close the indoor air inlet 13. Compared with the design method of moving the indoor air inlet 13, the rotating driving structure is simple, which can reduce the design and manufacturing cost.

[0067] like Figure 3 As shown, the valve plate 42 includes a first valve plate 421 and a second valve plate 422 disposed on both sides of the rotation axis of the rotating shaft 41. The first valve plate 421 and the second valve plate 422 are arranged non-coplanarly and connected to both sides of the rotating shaft 41. Figure 5 and Figure 6 As shown, when the valve 4b closes the indoor air inlet 13, the edge of the first valve plate 421 stops on the outside of the first stop edge 131, and the edge of the second valve plate 422 stops on the inside of the second stop edge 132.

[0068] It is worth mentioning that the inside and outside here are based on the airflow direction at the indoor air inlet 13 , and the airflow flows along the outside of the indoor air inlet 13 to the inside of the indoor air inlet 13 to enter the fresh air duct 11 .

[0069] The first stop edge 131 and the second stop edge 132 are provided to limit the rotation of the valve plate 42. When the valve 4b rotates until the first valve plate 421 abuts against the first stop edge 131 and the second valve plate 422 abuts against the second stop edge 132, it indicates that the valve 4b closes the indoor air inlet 13, thereby improving the over-rotation of the valve plate 42 and improving the reliability of the valve 4b in closing the indoor air inlet 13.

[0070] Furthermore, by designing the first valve disc 421 and the second valve disc 422 to be non-coplanar, the first valve disc 421 is stopped on the outside of the first stop edge 131, and the second valve disc 422 is stopped on the inside of the second stop edge 132, so that Figure 6 Taking the reference system shown as an example, the valve 4b can open the indoor air inlet 13 by rotating clockwise, and can close the indoor air inlet 13 by rotating counterclockwise, thereby improving the working reliability of the valve 4b. After the valve 4b closes the indoor air inlet 13, the valve 4b is stopped and cannot continue to rotate counterclockwise. When the airflow impacts the inside of the indoor air inlet 13 from the outside, the valve 4b will only be closed more tightly, thereby improving the working reliability of the valve 4b.

[0071] In some embodiments of the present invention, the rotating shaft 41 may be a solid shaft, and the first valve plate 421 and the second valve plate 422 are connected to two sides of the rotating shaft 41 .

[0072] In some other embodiments of the present invention, there are two rotating shafts 41 , which are coaxially arranged and disposed on both sides of the valve 4 b .

[0073] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the indoor air inlet 13 is rectangular, the rotation axis of the rotating shaft 41, the first valve plate 421 and the second valve plate 422 all extend along the length direction X of the indoor air inlet, and when the valve 4b closes the indoor air inlet 13, the first valve plate 421 and the second valve plate 422 are arranged on both sides of the rotating shaft 41 along the width direction Y of the indoor air inlet.

[0074] The rotating shaft 41 is extended along the length direction X of the indoor air inlet, and the first valve plate 421 and the second valve plate 422 rotate to sweep a smaller area, which is beneficial to the arrangement of the valve 4b and can improve the interference between the rotation of the valve 4b and other components.

[0075] In some embodiments of the present invention, Figure 4 As shown, the indoor air inlet 13 is rectangular, the first retaining edge 131 and the second retaining edge 132 are disposed on both sides of the width direction Y of the indoor air inlet, the first retaining edge 131 and the second retaining edge 132 are both semi-enclosed, the first retaining edge 131 defines the long side and two short sides of the indoor air inlet 13, and the second retaining edge 132 defines the other long side and two short sides of the indoor air inlet 13. There is a relief portion between the first retaining edge 131 and the second retaining edge 132 for escaping the installation of the rotating shaft 41, so that the rotating shaft 41 can be installed and rotated.

[0076] In some embodiments of the present invention, Figure 3 and Figure 6 As shown, the first valve disc 421 and the second valve disc 422 are symmetrical about the rotation axis of the rotating shaft 41 .

[0077] The first valve plate 421 and the second valve plate 422 are symmetrically arranged, the center of gravity of the valve 4b is located on the rotating shaft 41, the valve 4b rotates smoothly, the working reliability of the valve 4b can be improved, and the design and manufacture of the valve 4b are convenient.

[0078] In some embodiments of the present invention, Figure 4 As shown, the edge of the indoor air inlet 13 has a retaining edge 13a. Figure 2 As shown, the valve 4b includes: a rotating shaft 41 and a valve plate 42. The rotating shaft 41 is connected to the driver 4a so that the rotating shaft 41 is driven to rotate by the driver 4a. The valve plate 42 is connected to the rotating shaft 41. The valve plate 42 is rotatably arranged at the indoor air inlet 13 to open and close the indoor air inlet 13.

[0079] like Figure 4 and Figure 6 As shown, when the valve plate 42 closes the indoor air inlet 13, the edge of the valve plate 42 stops at the stop edge 13a, and the edge of the valve plate 42 has a reinforcing rib 43 protruding in a direction away from the stop edge 13a.

[0080] The valve plate 42 can be limited by setting the stop edge 13a. When the edge of the valve plate 42 stops at the stop edge 13a, it means that the valve 4b closes the indoor air inlet 13, which improves the situation of the valve plate 42 rotating too much and improves the reliability of the valve 4b closing the indoor air inlet 13.

[0081] By providing reinforcing ribs 43 at the edge of the valve plate 42, the structural strength of the valve plate 42 can be improved, and the valve plate 42 is not prone to bending and twisting, thereby improving the reliability of the valve plate 42 stopping at the retaining edge 13a. The valve plate 42 seals the indoor air inlet 13 tightly with good air tightness, and can improve the whistling sound generated when the fresh air component 100 is in operation.

[0082] By lifting the valve 4b to close the sealing of the indoor air inlet 13, when the fresh air component 100 delivers fresh air to the room, the situation where the outdoor fresh air directly escapes into the room from the indoor air inlet 13 can be reduced, thereby improving the working reliability of the fresh air component 100, reducing the abnormal sound generated by the fresh air flowing out from the indoor air inlet 13, and reducing the working noise.

[0083] In addition, the edge of the valve plate 42 stops at the stop edge 13a. Compared with setting the reinforcing rib 43 at the center of the valve plate 42, setting the reinforcing rib 43 at the edge of the valve plate 42 can improve the structural strength of the edge of the valve plate 42, and the edge of the valve plate 42 is not easy to deform, which can improve the sealing effect of the valve 4b on the indoor air inlet 13 and save manufacturing costs.

[0084] In some embodiments of the present invention, Figure 7As shown, the edge of the first valve plate 421 has a first reinforcement rib 431, and the first reinforcement rib 431 includes a first reinforcement section 4311 extending along the length direction X of the indoor air inlet, and a second reinforcement section 4312 extending from the first reinforcement section 4311 toward the direction of the rotating shaft 41. When the valve plate 42 closes the indoor air inlet 13, the first reinforcement rib 431 protrudes relative to the first valve plate 421 in a direction away from the first stop edge 131.

[0085] The edge of the second valve plate 422 has a second reinforcing rib 432, and the second reinforcing rib 432 includes a third reinforcing section 4321 extending along the length direction X of the indoor air inlet, and a fourth reinforcing section 4322 extending from the third reinforcing section 4321 toward the direction of the rotating shaft 41. When the valve plate 42 closes the indoor air inlet 13, the second reinforcing rib 432 protrudes relative to the second valve plate 422 in a direction away from the second blocking edge 132.

[0086] like Figure 6 As shown, when the valve disc 42 closes the indoor air inlet 13 , the first reinforcing rib 431 is located on the outside of the indoor air inlet 13 relative to the first valve disc 421 , and the second reinforcing rib 432 is located on the inside of the indoor air inlet 13 relative to the second valve disc 422 .

[0087] The first reinforcing rib 431 is arranged along the edge of the first valve plate 421 stopping the first stop edge 131, and the second reinforcing rib 432 is arranged along the edge of the second valve plate 422 stopping the second stop edge 132, which can improve the structural strength of the edge of the valve plate 42, and the valve plate 42 is not easy to bend and twist. The valve plate 42 is tightly sealed to the indoor air inlet 13, has good air tightness, and can improve the whistling sound generated when the fresh air component 100 is in operation.

[0088] Furthermore, the first reinforcing rib 431 includes an orthogonal first reinforcing section 4311 and a second reinforcing section 4312 , and the second reinforcing rib 432 includes an orthogonal third reinforcing section 4321 and a fourth reinforcing section 4322 , which can further enhance the structural strength of the valve plate 42 .

[0089] like Figure 4 As shown, the first retaining edge 131 and the second retaining edge 132 are disposed on both sides of the width direction Y of the indoor air inlet, and the first retaining edge 131 and the second retaining edge 132 are both in a semi-enclosed shape. The first retaining edge 131 defines a long side and two short sides of the indoor air inlet 13, and the second retaining edge 132 defines another long side and two short sides of the indoor air inlet 13.

[0090] The first reinforcing rib 431 includes a first reinforcing section 4311 and two second reinforcing sections 4312. The first reinforcing section 4311 extends along the length direction X of the indoor air inlet. The second reinforcing sections 4312 are connected to both ends of the first reinforcing section 4311. The second reinforcing section 4312 extends along the width direction Y of the indoor air inlet. The second reinforcing rib 432 includes a third reinforcing section 4321 and two fourth reinforcing sections 4322. The third reinforcing section 4321 extends along the length direction X of the indoor air inlet. The fourth reinforcing section 4322 is connected to both ends of the third reinforcing section 4321. The fourth reinforcing section 4322 extends along the width direction Y of the indoor air inlet.

[0091] In some embodiments, Figure 2 and Figure 7 As shown, the valve 4b includes a rotating shaft 41 and a valve plate 42, the rotating shaft 41 includes a first rotating shaft 411 and a second rotating shaft 412 which are arranged on both sides of the valve plate 42 along the rotation axis of the rotating shaft 41, the driver 4a is connected to one of the first rotating shaft 411 and the second rotating shaft 412, and the fresh air housing 1 includes a first supporting seat 15 supporting the first rotating shaft 411 and a second supporting seat 16 supporting the second rotating shaft 412.

[0092] There are two rotating shafts 41 , including a first rotating shaft 411 and a second rotating shaft 412 . The first rotating shaft 411 and the second rotating shaft 412 are coaxially arranged to drive the valve plate 42 to rotate. The valve plate 42 is rotatably arranged at the indoor air inlet 13 to open and close the indoor air inlet 13 .

[0093] It is worth mentioning that the first support seat 15 and the second support seat 16 are understood in a broad sense. The first support seat 15 and the second support seat 16 can be clamping members with a supporting function. The first support seat 15 and the second support seat 16 can also be structures that support the rotation of the rotating shaft 41, which all fall within the protection scope of the present utility model.

[0094] In some embodiments of the present invention, Figure 2 and Figure 8 As shown, the first support seat 15 is provided with a first shaft hole 151, and the second support seat 16 is provided with a second shaft hole 161. The first rotating shaft 411 passes through the first shaft hole 151, and the second rotating shaft 412 passes through the second shaft hole 161. The first support seat 15 and the second support seat 16 support and limit the rotating shaft 41.

[0095] like Figure 2 , Figure 8 and Fig. 9 As shown, the second support seat 16 is provided with an opening 162 located on one side of the second shaft hole 161 in the radial direction and connected to the second shaft hole 161 , the first rotating shaft 411 is axially inserted into the first shaft hole 151 , and the second rotating shaft 412 is radially inserted into the second shaft hole 161 through the opening 162 .

[0096] The installation process of the rotating shaft 41 is simple and easy to operate, which can improve the assembly efficiency of the valve 4b. In addition, during the assembly process of the rotating shaft 41 and the first support seat 15 and the second support seat 16, since the second shaft hole 161 has an opening 162 in the radial direction for the second rotating shaft 412 to pass through, the valve 4b does not need to be bent and deformed to insert the two ends of the rotating shaft 41 into the first shaft hole 151 and the second shaft hole 161, respectively, thereby reducing the difficulty of assembly and reducing damage to the valve 4b.

[0097] In some embodiments of the present invention, the diameter of the opening 162 is smaller than the diameter of the second shaft hole 161 , and the second shaft 412 will not fall out of the opening 162 after being installed in the second shaft hole 161 , thereby improving the rotation stability of the shaft 41 .

[0098] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the fresh air housing 1 is provided with an air inlet frame surrounding the indoor air inlet 13 at the indoor air inlet 13. The indoor air inlet 13 is rectangular, and two side plates of the air inlet frame in the width direction of the indoor air inlet 13 are respectively constructed as a first support seat 15 and a third support seat 17, and the second support seat 16 is installed on the third support seat 17.

[0099] like Fig. 9 and Fig.10 As shown, the second support seat 16 is constructed as a C-shaped structure. The second support seat 16 defines a second axial hole 161 inside. The second support seat 16 includes two elastic arms 163 that can generate elastic deformation. An opening 162 is defined between the two elastic arms 163.

[0100] When the second rotating shaft 412 is inserted into the second shaft hole 161 through the opening 162 in the radial direction, the two elastic arms 163 are squeezed to produce elastic deformation, and the diameter of the opening 162 becomes larger to allow the rotating shaft 41 to pass through. When the second rotating shaft 412 is installed in the second shaft hole 161, the two elastic arms 163 return to their original state, and the diameter of the opening 162 is smaller than the shaft diameter of the rotating shaft 41. After the second rotating shaft 412 is installed in the second shaft hole 161, it will not fall out of the opening 162, thereby improving the rotation stability of the rotating shaft 41.

[0101] like Fig. 9 As shown, the third support seat 17 is provided with an avoidance hole 171 for avoiding the second rotating shaft 412 , so that the second rotating shaft 412 can be radially inserted into the second shaft hole 161 .

[0102] In some embodiments of the present invention, Figure 2 and Figure 7 As shown, the outer diameter of the first rotating shaft 411 is smaller than the outer diameter of the second rotating shaft 412 .

[0103] In some embodiments of the present invention, Figure 2As shown, the driver 4a is a motor and is directly connected to the second rotating shaft 412 , and the second support base 16 is disposed on a side of the first support base 15 close to the driver 4a .

[0104] The second rotating shaft 412 is connected to the motor shaft of the motor. Compared with the first rotating shaft, the second rotating shaft needs to cooperate with the motor shaft and therefore has a larger shaft diameter. Therefore, opening 162 in the radial direction of the second shaft hole 161 with a larger hole diameter is more conducive to the installation and rotation stability of the rotating shaft 41.

[0105] In some embodiments of the present invention, Fig. 9 As shown, the motor is mounted on the third support seat 17 via fasteners.

[0106] In some embodiments of the present invention, the output shaft of the driver 4a is inserted into the second rotating shaft 412, and the two are matched with non-circular surface transmission to improve transmission stability and improve the rotation reliability of the valve 4b.

[0107] In some embodiments of the present invention, the second support seat 16 includes an elastic arm 163, and the opening 162 and the second shaft hole 161 are defined by the elastic arm 163. The elastic arm 16 is configured as a semi-enclosed structure, and the elastic arm 163 can generate elastic deformation to allow the second rotating shaft 412 to pass through and limit the second rotating shaft 412. The installation process of the rotating shaft 41 is simple and easy to operate, and at the same time, the damage to the valve 4b can be reduced.

[0108] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the fresh air outlet 12 and the indoor air inlet 13 are both located at the rear side of the fresh air housing 1 , and the indoor air inlet 13 is located below the fresh air outlet 12 .

[0109] The indoor air inlet 13 and the fresh air outlet 12 are arranged adjacent to each other, which is beneficial to the operation of the fresh air component 100. In cold winter, the outdoor fresh air is directly delivered to the room, which will cause the temperature at the outlet to drop sharply, and the indoor temperature difference is large, causing discomfort to the human body, and may also damage the internal components of the fresh air component 100, reducing the service life of the fresh air component 100. The fresh air outlet 12 and the indoor air inlet 13 are opened at the same time, and the indoor air is mixed with the outdoor air intake and delivered to the fresh air duct 11. The air flow mixing begins at the end of the fresh air duct 11. The difference between the air flow temperature in the fresh air duct 11 and the indoor temperature is small, which improves the damage of the internal components of the fresh air component 100 by the low-temperature airflow, and can gently deliver fresh air to the room, improving the air supply effect.

[0110] In some embodiments of the utility model, the fresh air component 100 also includes a filter element, which is arranged at the air inlet end of the fresh air duct 11. The incoming air from the fresh air outlet 12 and the indoor air inlet 13 flows through the filter element and then continues to flow along the fresh air duct 11 to improve the airflow quality.

[0111] By arranging the indoor air inlet 13 and the fresh air outlet 12 adjacent to each other, it is also beneficial to arrange the filter element so as to purify the air supplied from the fresh air outlet 12 and the indoor air inlet 13 .

[0112] In some embodiments of the present invention, Figure 1 As shown, a fresh air outlet 14 communicating with the fresh air duct 11 is also formed on the fresh air housing 1 , and the fresh air outlet 14 is located above the indoor air inlet 13 and the fresh air port 12 .

[0113] In some embodiments of the present invention, there are multiple fresh air outlets 14, and the fresh air outlets 14 are located at different positions of the fresh air housing 1, which can increase the air supply range of the fresh air component 100 and improve the air supply effect.

[0114] In some embodiments of the present invention, Figure 1 As shown, there are two fresh air outlets 14, one fresh air outlet 14 is located at the rear side of the fresh air shell 1, and is arranged on the same side as the fresh air port 12 and the indoor air inlet 13, and the other fresh air outlet 14 is located at the front side of the fresh air shell 1, which can improve the air supply range of the fresh air component 100.

[0115] The air conditioner 1000 according to the second aspect of the present invention will be described below with reference to the accompanying drawings.

[0116] According to some embodiments of the present invention, the air conditioner 1000 is as follows: Fig.11 and Fig.12 As shown, the air conditioner 1000 includes: a heat exchange and ventilation component 500 and a fresh air component 100, and the fresh air component 100 is the fresh air component 100 of the first aspect mentioned above.

[0117] According to the air conditioner 1000 of the embodiment of the utility model, by providing the fresh air component 100 of the first aspect, the air conditioner 1000 can perform multi-mode air supply, and the air supply effect is better.

[0118] In some embodiments of the present invention, Fig.11 As shown, the front side of the air conditioner 1000 has a front panel 600, a first air outlet 71 located above the front panel 600, and a second air outlet 72 located below the front panel 600, and the rear side of the air conditioner 1000 has a third air outlet.

[0119] The air conditioner 1000 has a first air outlet 71 and a second air outlet 72 arranged at intervals in the up-down direction, which can improve the air supply range of the air conditioner 1000 in the vertical direction. The air conditioner 1000 also has a first air outlet 71, a second air outlet 72 and a third air outlet arranged at the front and rear sides, respectively, which can improve the air supply range of the air conditioner 1000 in the horizontal direction.

[0120] The first air supply outlet 71 , the second air supply outlet 72 and the third air supply outlet can work independently of each other, or can cooperate with each other to supply air, thereby meeting different air supply requirements of the air conditioner 1000 .

[0121] In some embodiments of the present invention, Fig.12 and Fig.13 As shown, the heat exchange ventilation component 500 is disposed at the rear side of the front panel 600 and defines a heat exchange air duct 51, which is connected to the first air supply port 71. The fresh air component 100 is disposed below the heat exchange ventilation component 500, and the fresh air duct 11 is connected to the third air supply port.

[0122] The heat exchange airflow generated by the air conditioner 1000 flows through the heat exchange air duct 51 and can be sent out from the first air outlet 71 to participate in indoor temperature regulation. The fresh air flows through the fresh air duct 11 and can be sent out from the third air outlet to perform air circulation, improve indoor air quality, and increase freshness and remove turbidity.

[0123] In some embodiments of the present invention, Fig.14 As shown, the second air outlet 72 can be connected to the heat exchange air duct 51 or the fresh air duct 11. The air conditioner 1000 further includes a switching device 800 for switching the second air outlet 72 to be connected to one of the heat exchange air duct 51 and the fresh air duct 11.

[0124] The second air outlet 72 can be selectively connected to one of the heat exchange air duct 51 and the fresh air duct 11, so that the second air outlet 72 can deliver both the heat exchange airflow and the fresh air, and the air conditioner 1000 can achieve multi-mode air supply to meet the needs of different scenes. In addition, the air outlet of the air conditioner 1000 can be reduced, the structure of the air conditioner 1000 can be simplified, and the manufacturing difficulty of the air conditioner 1000 can be reduced.

[0125] like Fig.14 As shown, when the switching device 800 switches the second air supply port 72 to be connected with the heat exchange air duct 51, fresh air is delivered to the room through the third air supply port, and the heat exchange air is delivered to the room through the second air supply port 72. The dotted line with an arrow in the figure indicates the direction of air flow. While adjusting the indoor temperature, the indoor air quality can be improved to make the indoor air fresher.

[0126] When the switching device 800 switches the second air supply port 72 to be connected with the fresh air duct 11, the fresh air is delivered to the room via the third air supply port and the second air supply port 72, which can increase the fresh air intake volume and the air circulation speed.

[0127] In some embodiments of the present invention, Fig.14As shown, the fresh air component 100 includes two fresh air outlets 14, the first fresh air outlet 141 is located on the front side of the air conditioner 1000, and the second fresh air outlet 142 is located on the rear side of the air conditioner 1000, the first fresh air outlet 141 is connected to the second air supply port 72, and the second fresh air outlet 142 is connected to the third air supply port.

[0128] The fresh air duct 11 includes a first air duct 111 extending forwardly toward the second air supply port 72 , and a second air duct 112 extending backwardly toward the third air supply port. The switching device 800 is used to switch the first air duct 111 and the second air supply port 72 on and off.
