[0038] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0040] Next, with reference to the drawings, a fresh air component 100 according to an embodiment of the present invention will be described.

[0041] As Figures 1-7 shown, the fresh air component 100 according to an embodiment of the present invention includes: a duct structure 1, a humidifying member 2, and a flow guiding member 3. A duct 11 is defined within the duct structure 1; the humidifying member 2 is disposed within the duct 11, and the two sides of the humidifying member 2 in the thickness direction F1 are respectively an upstream side 2a and a downstream side 2b; the flow guiding member 3 is disposed within the duct 11 and is located on the upstream side 2a of the humidifying member 2, and includes a flow guiding surface 30a that guides the airflow in the direction towards the humidifying member 2.

[0042] Thereby, the air resistance of the airflow within the duct 11 can be reduced, which is beneficial to increasing the air volume, enhancing the humidifying effect, and can also reduce noise, improving the practicality of the fresh air component 100.

[0043] For example, as Figures 1-4 shown, the fresh air component 100 includes a duct structure 1 and a humidifying member 2. A duct 11 is defined within the duct structure 1, the humidifying member 2 is disposed within the duct 11, and the two sides of the humidifying member 2 in the thickness direction F1 are respectively an upstream side 2a and a downstream side 2b. Indoor air and / or outdoor fresh air can flow into the duct 11 to flow towards the upstream side 2a of the humidifying member 2. The humidifying member 2 can humidify the airflow, and the humidified airflow can flow into the indoor space from the downstream side 2b of the humidifying member 2 to humidify the indoor space. By way of example, the humidifying member 2 can be configured as a wet film structure.

[0044] Among them, it can be provided that the fresh air component 100 further includes a flow guiding member 3. The flow guiding member 3 is disposed within the duct 11, and the flow guiding member 3 is located on the upstream side 2a of the humidifying member 2. The flow guiding member 3 includes a flow guiding surface 30a, and the flow guiding surface 30a is used to guide the airflow flowing through the flow guiding member 3 towards the humidifying member 2, so that the airflow can pass through the humidifying member 2 more smoothly. Thereby, the obstruction of the humidifying member 2 to the airflow can be reduced, which is beneficial to reducing noise.

[0045] The fresh air component 100 according to the embodiment of the present invention can direct the airflow in the air duct 11 to the humidifying member 2 by providing the flow guiding surface 30a, which can reduce the wind resistance of the airflow in the air duct 11, facilitate increasing the air volume, improve the humidifying effect, and can reduce noise, thereby enhancing the practicality of the fresh air component 100.

[0046] In some embodiments of the present invention, the thickness direction F1 of the humidifying member 2 is not parallel to the normal direction F2 of the cross-section S at the position where the flow guiding member 3 is provided in the air duct 11; the extending direction F3 of the flow guiding surface 30a from the inlet end to the outlet end of the flow guiding surface 30a is inclined relative to the normal direction F2 of the cross-section S towards the thickness direction F1 of the humidifying member 2.

[0047] For example, with reference to Figure 2 As shown, the flow guiding surface 30a is provided with an inlet end and an outlet end, and the airflow can flow from the inlet end to the flow guiding surface 30a and flow along the flow guiding surface 30a, so that the airflow can flow from the outlet end to the humidifying member 2. The thickness direction F1 of the humidifying member 2 is not parallel to the direction F2 of the cross-section S at the position where the flow guiding member 3 is provided in the air duct 11, that is, the thickness direction of the humidifying member forms a first included angle with the flow direction of the airflow when flowing towards the inlet end. Among them, the extending direction F3 of the flow guiding surface 30a from the inlet end to the outlet end can be set to be inclined relative to the normal direction F2 of the cross-section S towards the thickness direction F1 of the humidifying member 2, so that the flow direction of the airflow when flowing out from the outlet end can be parallel to the thickness direction F1 of the humidifying member 2 or form a second included angle, and the second included angle is smaller than the first included angle.

[0048] Through the above settings, the airflow can better pass through the humidifying member 2, which is beneficial to reducing the wind resistance, increasing the air volume, and is conducive to reducing noise.

[0049] In some embodiments of the present invention, the included angle between the extending direction F3 of the flow guiding surface 30a from the inlet end to the outlet end of the flow guiding surface 30a and the thickness direction F1 of the humidifying member 2 is less than or equal to 20°. For example, with reference to Figure 2 As shown, the flow guiding surface 30a is provided with an inlet end and an outlet end, and the airflow can flow from the inlet end to the flow guiding surface 30a and flow along the flow guiding surface 30a, so that the airflow can flow from the outlet end to the humidifying member 2. A second included angle is formed between the extending direction F3 of the flow guiding surface 30a from the inlet end to the outlet end and the thickness direction F1 of the humidifying member 2, that is, a second included angle is formed between the flow direction of the airflow flowing through the flow guiding member 3 and the thickness direction F1 of the humidifying member 2, and the angle of the second included angle is set to be less than or equal to 20 degrees.

[0050] For example, the second included angle can be taken as 15°; alternatively, the second included angle can be taken as 10°; or the second included angle can be taken as 5°. The present application does not limit this. Of course, it is also possible to set the extension direction F3 of the flow guiding surface 30a from the inlet end to the outlet end to be parallel to the thickness direction F1 of the humidifying member 2, that is, the second included angle is 0°. Through the above settings, the wind resistance can be reduced, the air volume can be increased, which is beneficial to reducing noise and improving the practicability of the fresh air component 100.

[0051] It should be emphasized that it is not absolute that the wind resistance decreases as the angle of the second included angle becomes smaller. For example, the wind resistance may be the smallest when the second included angle is 10°.

[0052] In some embodiments of the present invention, the flow guiding member 3 includes a plurality of flow guiding ribs 30 arranged at intervals, and the air flow is adapted to pass through the flow guiding member 3 through the gaps between adjacent flow guiding ribs 30, and the surface of the flow guiding ribs 30 is configured as the flow guiding surface 30a.

[0053] For example, with reference to Figures 5-6 As shown, the flow guiding member 3 includes a plurality of flow guiding ribs 30, the plurality of flow guiding ribs 30 are arranged at intervals, and gaps are formed between adjacent flow guiding ribs 30. When the air flow flows towards the flow guiding member 3, the air flow can pass through the flow guiding member 3 through the gaps between adjacent flow guiding ribs 30. The outer surface of the flow guiding ribs 30 is configured as the flow guiding surface 30a, and the air flow flowing through the flow guiding member 3 can flow along the flow guiding surface 30a towards the humidifying member 2. Through the above settings, both the ventilation of the flow guiding member 3 can be ensured, and the flow guiding member 3 can have a good and comprehensive flow guiding effect, improving the design rationality of the fresh air component 100.

[0054] Of course, the present application is not limited to this, and the flow guiding member 3 can also be set as a single flow guiding vane, and the present application does not limit this.

[0055] In some embodiments of the present invention, the flow guiding member 3 is in the form of a grille and includes a plurality of first ribs 31 arranged in parallel and a plurality of second ribs 32 arranged in parallel. The first ribs 31 and the second ribs 32 are arranged in a crosswise manner. Among them, the humidifying member 2 is inclined to the horizontal plane and is located above the flow guiding member 3, and the first ribs 31 serve as the flow guiding ribs 30 and the length direction is parallel to the length direction of the lower end of the humidifying member 2.

[0056] For example, with reference to Figures 5-6 As shown, the flow guiding member 3 includes a plurality of first ribs 31 and a plurality of second ribs 32. The plurality of first ribs 31 are arranged in parallel at intervals, and the plurality of second ribs 32 are arranged in parallel at intervals along the length direction of the first ribs 31, so that the first ribs 31 and the second ribs 32 are arranged in a crosswise manner, thereby constructing the flow guiding member 3 in the form of a grille. Thus, the flow guiding member 3 can have good structural strength and can also be used for safety protection to prevent sundries from moving in the air duct 11.

[0057] Among them, the humidifying member 2 can be arranged above the flow guiding member 3, so that the air flow can flow through the flow guiding member 3 and flow upward to the humidifying member 2. The humidifying member 2 is arranged obliquely to the horizontal plane, so that the humidifying member 2 has a larger contact area with the air flow, which is beneficial to improving the humidifying efficiency. The first rib 31 is set as the flow guiding rib 30, the length direction of the first rib 31 is parallel to the length direction of the lower end of the humidifying member 2, and a plurality of first ribs 31 are arranged at intervals along the extending direction of the humidifying member 2 and are all opposite to the humidifying member 2. A plurality of first ribs 31 can guide the air flow to the humidifying member 2, so that the air flow guiding of the plurality of first ribs 31 is sufficient and effective, which is beneficial to reducing the size of the flow guiding member 3. Thus, the design rationality of the fresh air component 100 is improved.

[0058] In some embodiments of the present invention, the air duct structure 1 includes an air outlet frame 12, the humidifying member 2 is arranged in the air outlet frame 12, the air outlet frame 12 includes a water tank 122, the humidifying member 2 extends into the water tank 122 to absorb water, and the fresh air component 100 further includes a water tank 4 for supplying water to the water tank 122.

[0059] For example, referring to Figures 2-3 As shown, the air duct structure 1 includes an air outlet frame 12. The air outlet frame 12 is adapted to define an air outlet section 11a of the air duct 11, and the humidifying member 2 is arranged in the air outlet section 11a. A water tank 122 is arranged on the air outlet frame 12, and the water tank 122 is used for storing water. When the humidifying member 2 is installed on the air outlet frame 12, a part of the humidifying member 2 can extend into the water tank 122 to absorb water, so that the surface of the humidifying member 2 can be covered with moisture, so that the humidifying member 2 can humidify the air flow flowing through the humidifying member 2. Among them, the fresh air component 100 further includes a water tank 4, the water tank 4 is used for storing water, the water tank 4 is provided with a valve, and the water tank 4 can selectively add water to the water tank 122 through the valve, so that the water tank 122 can supply sufficient water to the humidifying member 2.

[0060] Through the above settings, the fresh air component 100 can supply water to the humidifying member 2 stably and continuously, so as to ensure that the humidifying member 2 can effectively humidify the air flow, and the reliability of the fresh air component 100 is improved.

[0061] In some embodiments of the present invention, the air outlet frame 12 includes a frame body 121, a first groove 1221 arranged on the outer side of the frame body 121 and extending in the front-rear direction, and a second groove 1222 located in the rear part of the frame body 121 and extending in the left-right direction. The frame body 121 has a through hole 1223 communicating the first groove 1221 and the second groove 1222. The water tank 4 is arranged on the front side of the air outlet frame 12 and is adapted to supply water to the first groove 1221. The humidifying member 2 is arranged obliquely with the front end higher than the rear end and the lower end extends into the second groove 1222.

[0062] For example, referring to Figures 2-5As shown, the air outlet frame 12 includes a frame body 121, a first slot 1221 and a second slot 1222. The first slot 1221 is provided at the side of the frame body 121 along the left-right direction, and the length direction of the first slot 1221 extends along the front-back direction. The second slot 1222 is located at the rear of the frame body 121, and the length direction of the second slot 1222 extends along the left-right direction. The second slot 1222 is provided along one side of the left-right direction (i.e. Figure 5 The left side in the figure is opposite to the rear side of the first groove 1221, and the frame 121 has a through hole 1223, which is used to connect the first groove 1221 and the second groove 1222 so that water in the first groove 1221 and water in the second groove 1222 can flow to each other.

[0063] Among them, the water tank 4 can be arranged on the front side of the air outlet frame 12, and the water tank 4 is connected to the front side of the first groove 1221, so that the water tank 4 can supply water to the first groove 1221, and the humidifier 2 is arranged in the frame body 121, and the humidifier 2 is tilted with the front higher and the back lower. The lower end (i.e., the rear end) of the humidifier 2 can extend into the second groove 1222, so that the water tank 4 can supply water to the humidifier 2 through the first groove 1221 and the second groove 1222.

[0064] Through the above arrangement, the humidification area of ​​the humidifying element 2 can be increased, the humidification efficiency can be improved, and the overall layout of the fresh air component 100 can be made compact, which is beneficial to improving space utilization.

[0065] In some embodiments of the present invention, the air duct structure 1 also includes a volute 13 arranged at the front part of the lower part of the air outlet frame 12, and the front part of the lower end of the air outlet frame 12 has a connecting port 123 connected to the volute 13. The front wall of the air outlet frame 12 partially extends backward so that the front side of the air outlet frame 12 forms an escape space 120 for accommodating the water tank 4. The upper end of the humidifier 2 is located directly behind the water tank 4, and the humidifier 2 is tilted high at the front and low at the back, so that the upper end of the humidifier 2 is located directly above the connecting port 123, and the lower end is located obliquely rearward of the connecting port 123. The guide member 3 is arranged at the connecting port 123, and the guide surface 30a extends backward from bottom to top.

[0066] For example, refer to Figure 2 , Figure 3 and Figure 6 As shown, the air duct structure 1 further includes a volute 13, which is arranged at the lower front part of the air outlet frame 12, and a communication port 123 is arranged at the lower front part of the air outlet frame 12, and the communication port 123 is used to communicate with the volute 13, and the volute 13 is formed with an air inlet section 11b, and the air outlet section 11a and the air inlet section 11b are suitable for jointly defining the air outlet 11. The front wall of the air outlet frame 12 partially extends backward, such as the upper area of ​​the front wall of the air outlet frame 12 is arranged to extend upward from front to back, so that the front side of the air outlet frame 12 can form a rear concave avoidance space 120, and the avoidance space 120 is used to accommodate the water tank 4.

[0067] Meanwhile, the humidifying member 2 is configured to be inclined with the front end higher than the rear end. The upper end (i.e., the front end) of the humidifying member 2 is disposed directly behind the water tank 4, so that the upper end (i.e., the front end) of the humidifying member 2 is directly above the communication port 123. The lower end (i.e., the rear end) of the humidifying member 2 can extend backward to the obliquely rear of the communication port 123, and the lower end of the humidifying member 2 can be inserted into the water tank 122. A flow guiding member 3 is provided at the communication port 123. The flow guiding surface 30a of the flow guiding member 3 is configured to extend obliquely backward from bottom to top. The flow guiding member 3 can guide the air flow to the humidifying member 2, so that the air flow is parallel or approximately parallel to the thickness direction F1 of the humidifying member 2, thereby reducing the wind resistance.

[0068] Through the above settings, the installation of the water tank 4 can be made compact, which is conducive to reducing the overall size of the fresh air component 100. Moreover, the humidifying member 2 can have a larger humidifying area when the water tank 4 is installed, improving the humidifying efficiency of the fresh air component 100.

[0069] In some embodiments of the present invention, the part of the front wall of the air outlet frame 12 that is higher than the humidifying member 2 is the front air guiding wall 124. The front air guiding wall 124 is formed as a rear concave curved surface, and there is a spaced space P between the front air guiding wall 124 and the rear surface of the water tank 4.

[0070] For example, as shown in Figure 6 the part of the front wall of the air outlet frame 12 that is higher than the humidifying member 2 can be set as the front air guiding wall 124. The front air guiding wall 124 is configured to extend obliquely upward from front to rear, so that the front air guiding wall 124 can be formed as a rear concave curved surface. There is a spaced space P between the outer side wall of the front air guiding wall 124 and the rear surface of the water tank 4, so that the air outlet frame 12 can avoid the water tank 4, reducing the vibration transmission and heat transfer between the water tank 4 and the air outlet frame 12, which is beneficial to improving the working stability of the air outlet frame 12. In addition, the inner side wall of the front air guiding wall 124 can guide the air flow in the air duct 11, improving the flow stability of the air flow in the air duct 11 and facilitating noise reduction. Thus, the reliability of the fresh air component 100 is improved.

[0071] In some embodiments of the present invention, as shown in Figure 2 the water tank 4 can be installed on the air outlet frame 12. Through the above settings, the integration degree of the fresh air component 100 can be improved, the installation difficulty of the fresh air component 100 is reduced, and the cooperation stability between the water tank 4 and the air outlet frame 12 can be improved, which is beneficial to improving the water supply stability of the water tank 4 and improving the reliability of the fresh air component 100.

[0072] In some embodiments of the present invention, as shown in Figure 2 and Figure 4As shown in the figure, the air outlet frame 12 is provided with a bracket 125. The bracket 125 is located at the front part of the air outlet frame 12. The bracket 125 includes an extension part 1251 and a flanging part 1252. The extension part 1251 is connected to the front wall of the air outlet frame 12 and extends forward. The flanging part 1252 is connected to the front side edge of the extension part 1251 and protrudes upward, so as to construct the bracket 125 into an L-shaped structure. When the water tank 4 is installed on the air outlet frame 12, the extension part 1251 of the bracket 125 can support on the bottom of the water tank 4, and the flanging part 1252 can limit the front side of the water tank 4, so as to realize the installation cooperation between the water tank 4 and the air outlet frame 12. Thus, the installation stability of the water tank 4 can be improved.

[0073] It should be emphasized that the water tank 4 can be supported on the bracket 125, and then the water tank 4 is fixedly connected to the air outlet frame 12 to improve the installation stability of the water tank 4; or the water tank 4 can be directly supported on the bracket 125 to realize the installation cooperation between the water tank 4 and the bracket 125, so as to reduce the installation difficulty of the water tank 4.

[0074] In some embodiments of the present invention, the air duct structure 1 includes an air outlet frame 12. The humidifying member 2 is arranged in the air outlet frame 12. The air outlet frame 12 is provided with two air outlets 126. The air outlet frame 12 includes a flow splitting structure 127. The flow splitting structure 127 is located downstream of the humidifying member 2 and guides the air flow toward the two air outlets 126 respectively.

[0075] For example, with reference to Figures 3-4 As shown in the figure, the air duct structure 1 includes an air outlet frame 12. The air outlet frame 12 defines the air outlet section 11a of the air duct 11. The humidifying member 2 is arranged in the air outlet section 11a. The air outlet frame 12 has two air outlets 126. The two air outlets 126 are symmetrically arranged. For example, the two air outlets 126 can be respectively arranged on the left and right sides of the air outlet frame 12. The air outlet frame 12 includes a flow splitting structure 127. The flow splitting structure 127 is located downstream of the humidifying member 2. The flow splitting structure 127 is arranged between the two air outlets 126. The flow splitting structure 127 can be constructed into a V shape. The flow splitting structure 127 is used to respectively guide the air flow flowing through the humidifying member 2 to the two air outlets 126, so that the air flow in the air duct 11 can flow into the room from the two air outlets 126 respectively. Thus, the humidifying uniformity of the fresh air component 100 can be improved, which is beneficial to improving the humidifying effect.

[0076] In some embodiments of the present invention, as Figure 2 and Figure 6 shown, one end of the flow splitting structure 127 close to the humidifying member 2 is set as the inflow end 127a. The inflow end 127a of the flow splitting structure 127 can be arranged parallel to the downstream surface 21 of the humidifying member 2, so as to make the gap between the flow splitting structure 127 and the humidifying member 2 uniform. Thus, the flow guiding effect of the flow splitting structure 127 can be ensured, which is beneficial to reducing the turbulence in the air duct 11 and reducing the noise.

[0077] In some embodiments of the present invention, as Figure 6 shown, one end of the flow splitting structure 127 facing the humidifying member 2 is set as the inflow end 127a, and the distance H between the inflow end 127a of the flow splitting structure 127 and the downstream surface 21 of the humidifying member 2 can be set to be 2 mm - 100 mm. It should be noted that the inflow end 127a of the flow splitting structure 127 can be arranged parallel to the downstream surface 21 of the humidifying member 2 or non-parallelly arranged, and the present application does not limit this.

[0078] For example, the inflow end 127a of the flow splitting structure 127 can be arranged parallel to the downstream surface 21 of the humidifying member 2, and the distance H between the inflow end 127a of the flow splitting structure 127 and the downstream surface 21 of the humidifying member 2 can be taken as 10 mm, or 50 mm, or 90 mm. Or, the inflow end 127a of the flow splitting structure 127 can be arranged non-parallelly to the downstream surface 21 of the humidifying member 2, the minimum value of the distance H between the inflow end 127a of the flow splitting structure 127 and the downstream surface 21 of the humidifying member 2 is taken as 10 mm, and the maximum value is taken as 20 mm. Thus, it is beneficial to meet different working conditions.

[0079] In some embodiments of the present invention, the air outlet frame 12 has a push-pull opening 128, and the air outlet frame 12 has a guide rail structure 129 inside. The humidifying member 2 is in guiding cooperation with the guide rail structure 129 and is adapted to enter and exit the air outlet frame 12 through the push-pull opening 128, and the two air outlet openings 126 are located on both sides of the air outlet frame 12 in the length direction of the push-pull opening 128.

[0080] For example, referring to Figure 3 、 Figure 4 and Figure 6 shown, a push-pull opening 128 can be provided on the air outlet frame 12, and the push-pull opening 128 opens outward. The air outlet frame 12 has a guide rail structure 129 inside, and the guide rail structure 129 is used for guiding cooperation with the humidifying member 2 to movably mount the humidifying member 2 on the air outlet frame 12. The guide rail structure 129 is arranged opposite to the push-pull opening 128, and the humidifying member 2 can move relative to the guide rail structure 129 so that the humidifying member 2 can enter and exit the air outlet frame 12 through the push-pull opening 128. The length direction of the push-pull opening 128 extends in the left-right direction, and the two air outlet openings 126 are arranged on both sides of the air outlet frame 12 in the length direction of the push-pull opening 128 so that the two air outlet openings 126 are symmetric about the humidifying member 2.

[0081] Through the above settings, the humidifying member 2 is easy to disassemble and assemble, facilitating subsequent maintenance, and the air flow rates blown out from the two air outlet openings 126 can be made similar, which is beneficial to improving the air outlet effect of the fresh air component 100 and improving the practicability of the fresh air component 100.

[0082] In some embodiments of the present invention, it may be arranged that the guide rail structure 129 includes two sets of sliding guide rails 1291. The two sets of sliding guide rails 1291 are arranged at intervals on the opposite sides of the air outlet frame 12 along the length direction of the push-pull opening 128. Each set of sliding guide rails 1291 includes two sliding guide rails 1291. The two sliding guide rails 1291 are arranged at intervals along the width direction of the push-pull opening 128. The two sliding guide rails 1291 extend parallel in a direction away from the push-pull opening 128. A sliding space is defined between the two sliding guide rails 1291. The side part of the humidifying member 2 is adapted to extend into the sliding space and slidably cooperate with the sliding guide rails 1291. Thus, the movement stability of the humidifying member 2 can be improved.

[0083] Furthermore, it may be arranged that the distance between the two sliding guide rails 1291 is slightly larger than the thickness of the humidifying member 2. Thus, the humidifying member 2 can be easily slid into the sliding space.

[0084] Furthermore, it may be arranged that the protruding height of the sliding guide rail 1291 is 2 mm - 5 mm, and the thickness of the sliding guide rail 1291 is 2 mm - 3 mm. Thus, the limiting effect of the sliding guide rail 1291 can be ensured.

[0085] In some embodiments of the present invention, it may be arranged that a partial depression is formed on the outer surface of the air outlet frame 12 to form a flow splitting structure 127. Thus, the installation difficulty of the air outlet frame 12 can be reduced, the stability of the flow splitting structure 127 is improved, and the reliability of the fresh air component 100 is improved.

[0086] In some other embodiments of the present invention, it may be arranged that the flow splitting structure 127 is a separately formed partition member, and the partition member is used for being installed in the air outlet frame 12 to split the air flow. Thus, the processing difficulty of the air outlet frame 12 can be reduced, the processing cost is reduced, and when the partition member is damaged, the partition member can be disassembled, replaced or repaired, which is beneficial to reducing the maintenance cost.

[0087] The present invention also proposes an air conditioner 1000.

[0088] As Figure 7 shown, the air conditioner 1000 according to an embodiment of the present invention includes the fresh air component 100 according to any one of the above-mentioned embodiments.

[0089] For the air conditioner 1000 according to an embodiment of the present invention, by arranging the guide surface 30a, the air flow in the air duct 11 can be guided to the humidifying member 2, the wind resistance of the air flow in the air duct 11 can be reduced, which is beneficial to increasing the air volume, improving the humidifying effect, and can reduce the noise, improve the practicability of the fresh air component 100, and enhance the overall performance of the air conditioner 1000.

[0090] In some embodiments of the present invention, as Figure 7As shown, the air conditioner 1000 can be a floor-standing air conditioner, which is suitable for installation indoors to adjust the indoor space. The fresh air component 100 is located at the lower part of the air conditioner 1000 and is the fresh air component 100 according to any one of the above embodiments. There is a fresh air duct at the rear of the air conditioner 1000, and the fresh air duct is suitable for connecting the outdoors and the fresh air component 100, so that outdoor fresh air can flow into the air duct 11 of the fresh air component 100 through the fresh air duct. At the same time, air outlets 200 can be respectively provided on the left and right sides of the housing of the air conditioner 1000. The two air outlets 200 correspond to the two air outlets 126 one by one and are both connected to the indoors.

[0091] In the specific working process, when the air conditioner 1000 is in the fresh air humidification mode, the fan of the air conditioner 1000 starts to operate. Outdoor fresh air can flow into the air duct 11 of the fresh air component 100 from the fresh air duct. The air flow can flow along the air duct 11 to the deflector 3, and the deflector 3 is used to direct the air flow to the humidifying member 2 so that the humidifying member 2 can humidify the air flow. The humidified air flow flows along the air duct 11 to the flow splitting structure 127, and the flow splitting structure 127 divides the air flow into two parts. The two fresh air flows respectively flow to the two air outlets 126 and are respectively blown into the room through the two air outlets 200, thereby humidifying the room. Thus, the practicability of the air conditioner 1000 is improved.
