[0040] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0042] like Figures 1 to 8 As shown, the embodiment of the present disclosure provides a fresh air system 20, which can power the fresh air device 21 through a solar power supply device 23, so as to reduce the energy consumption of the fresh air device 21 while ensuring long-term operation of the fresh air device 21, and provide a better user experience.

[0043] like Figures 1 to 8As shown, the embodiment of the present disclosure provides a fresh air system 20 comprising: a fresh air device 21, a fresh air duct 22, a solar power supply device 23, and a control module. The fresh air device 21 comprises a housing, which is mounted on the outer facade of the wall at a position corresponding to the window; the fresh air duct 22 is used to connect the fresh air device 21 and the window, and the fresh air device 21 can supply air to the room through the fresh air duct 22; the solar power supply device 23 is mounted on the outer wall and / or top surface of the housing and is electrically connected to the fresh air device 21; the control module is electrically connected to the solar power supply device 23 and the fresh air device 21 respectively, and is used to control the fresh air device 21 to turn on or off the energy-saving mode; when the fresh air device 21 is in energy-saving mode, the solar power supply device 23 supplies power to the fresh air device 21.

[0044] Specifically, the casing of the fresh air device 21 can be installed on the facade of the wall by means of fasteners such as expansion bolts, and the casing is located on the outside of the window. The fresh air device 21 also includes a centrifugal DC fan 24, which is arranged in the casing. The casing is provided with an air inlet 211 connected to the outdoor communication pipe and an air outlet 212 connected to the fresh air duct 22. When the fresh air device 21 is running, the fan 24 can inhale outdoor air through the air inlet 211, and blow the air into the room through the air outlet 212 and the fresh air duct 22 to improve the indoor air quality, such as Figure 4 As shown. The solar power supply device 23 is fixedly mounted on the outer wall and / or top surface of the housing to obtain solar energy. At the same time, the solar power supply device 23 is electrically connected to the fan 24 to supply power to the fan 24.

[0045] When there is sufficient sunlight outside, the control module can control the fresh air device 21 to turn on the energy-saving mode. At this time, the solar power supply device 23 can supply power to the fan 24 to ensure the continuous operation of the fan 24, thereby ensuring that the fresh air device 21 can continuously supply air to the room.

[0046] With such a configuration, the fresh air device 21 can be powered by the solar power supply device 23, so as to reduce the energy consumption of the fresh air device 21 while ensuring that the fresh air device 21 runs for a long time, and the user experience is better.

[0047] In the above embodiment, when the fresh air device 21 is in energy-saving mode, the solar power supply device 23 supplies power to the fresh air device 21 alone, so as to achieve the effect of reducing energy consumption.

[0048] Optionally, the housing is provided with an air inlet 211, and a primary filter 25 is provided at the air inlet 211. The primary filter 25 can preliminarily filter the air flowing through the air inlet 211 to improve the air quality of the air flowing into the room.

[0049] Optionally, a high efficiency filter 26 is further provided at the air inlet 211, and the high efficiency filter 26 is provided on one side of the primary filter 25 close to the fresh air duct 22. The high efficiency filter 26 can further filter the air flowing through the air inlet 211 to further improve the air quality of the air flowing into the room.

[0050] In some embodiments, the fresh air device 21 is further electrically connected to the power grid. The fresh air system 20 further includes a detection module. The detection module is electrically connected to the control module and the solar power supply device 23, respectively, and is configured to obtain the output power P of the solar power supply device 23. When the output power P is less than or equal to a first preset power P1, the control module controls the fresh air device 21 to disable the energy-saving mode and supply power to the fresh air device 21 via the power grid.

[0051] Specifically, the detection module is electrically connected to the solar power supply device 23 to obtain the output power P of the solar power supply device 23, and determines that the solar power supply device 23 is in low power mode when the output power P is less than or equal to the first preset power P1. The detection module is also electrically connected to the control module. When the solar power supply device 23 is in low power mode, the detection module sends a low power signal to the control module. After the control module receives the low power signal, the control module controls the fresh air device 21 to turn off the energy-saving mode and supplies power to the fresh air device 21 through the power grid. Such a setting can prevent the solar power supply device 23 from being unable to stably drive the fresh air device 21 to operate, thereby preventing the fresh air device 21 from being unable to continuously supply air to the room.

[0052] When the energy-saving mode of the fresh air device 21 is turned off, the control module can control the power grid and the solar power supply device 23 to supply power to the fresh air device 21 at the same time to save energy, or control the power grid to supply power to the fresh air device 21 alone.

[0053] In the above embodiment, the output power P of the solar power supply device 23 refers to the power output by the solar power supply device 23 to the wind turbine 24 .

[0054] In actual applications, the first preset power P1 can be set according to the actual needs of the user. For example, the user can set the first preset power P1 according to the rated power of the fan 24.

[0055] like Figure 2 and Figure 5 As shown, in some embodiments, the outer wall and / or top surface of the housing is provided with a mounting groove 213, and the mounting groove 213 is used to install the solar power supply device 23; wherein, the depth of the mounting groove 213 is less than or equal to the thickness of the solar power supply device 23.

[0056] Specifically, the outer wall of the housing defines a mounting groove 213, within which the solar power supply device 23 is mounted to prevent it from being detached from the housing. Furthermore, the depth of the mounting groove 213 is less than or equal to the thickness of the solar power supply device 23, preventing the solar power supply device 23 from being completely embedded within the mounting groove 213. This, in turn, prevents the sidewalls of the mounting groove 213 from blocking sunlight and reducing the output power of the solar power supply device 23.

[0057] In some embodiments, a fixing portion is provided in the mounting groove 213 , and the solar power supply device 23 can be fixedly installed on the fixing portion.

[0058] Specifically, a snap-fit ​​structure such as a buckle is provided in the mounting groove 213, or a fastener such as a screw or bolt is provided to form a fixing portion. In this way, the user can fix the solar power supply device 23 in the mounting groove 213 through the fixing portion to prevent the solar power supply device 23 from being separated from the mounting groove 213.

[0059] In some embodiments, the fresh air system 20 further includes a power storage device. The power storage device is connected to the fresh air device 21 and the solar power supply device 23, respectively, and is configured to supply power to the fresh air device 21. When the output power P is greater than or equal to the second preset power P2, the solar power supply device 23 can supply power to the power storage device.

[0060] Specifically, the power storage device can be a battery. The power storage device is installed in the housing and can supply power to the fresh air device 21. When the output power P is greater than or equal to the second preset power P2, the detection module determines that the solar power supply device 23 is in high power mode and sends a high power signal to the control module. After receiving the high power signal, the control module controls the solar power supply device 23 to supply power to the power storage device, and the power storage device can store electrical energy. In this way, when the detection module determines that the solar power supply device 23 is in low power mode, the control module can control the power storage device to supply power to the fresh air device 21 to further reduce energy consumption.

[0061] In practical applications, the second preset power P2 can be set according to the actual needs of the user. For example, the second preset power P2 can be 1.5 times or 2 times the rated power of the fan 24.

[0062] like Figure 1 As shown in FIG8 , in some embodiments, a window includes a window frame 11 and a window body 10, wherein the window body 10 is rotatably mounted on the window frame 11. The fresh air system 20 further includes a position sensor 15. The position sensor 15 is disposed at positions corresponding to the window frame 11 and the window body 10, and is used to detect the position of the window body 10. The position sensor 15 is electrically connected to a control module, so that the control module can turn on or off the fresh air device 21 according to the position of the window body 10.

[0063] Specifically, the window body 10 is located on the indoor side of the fresh air device 21. Thus, the user can rotate the window body 10 toward the indoor side, that is, rotate it away from the fresh air device 21 to open the window body 10; the user can also rotate the window body 10 toward the outdoors to a position corresponding to the window frame 11, that is, rotate it toward the fresh air device 21 to close the window body 10.

[0064] When the user rotates the window body 10 toward the room, the position sensor 15 determines that the window body 10 is in the open state and sends an opening signal to the control module. At this time, the control module can control the fresh air device 21 to open to transport outdoor air into the room.

[0065] When the user rotates the window body 10 toward the outside to a position corresponding to the window frame 11, the position sensor 15 determines that the window body 10 is in a closed state. At this time, the control module can control the fresh air device 21 to be closed to reduce energy consumption.

[0066] With such a configuration, the position sensor 15 can be used to determine whether the user has opened the window, and the opening or closing of the fresh air device 21 can be controlled according to the window opening status. The methods of controlling the fresh air device 21 are more diverse, thereby improving the user experience.

[0067] In the above embodiment, the position sensor 15 controls the fresh air device 21 to be turned off, which may be to control the fresh air device 21 to be completely shut down, or to control the fresh air device 21 to be in a standby state.

[0068] It is understandable that a sealing structure is provided in the gap between the fresh air device 21 and the window to prevent outdoor air from directly flowing into the room when the window body 10 is opened.

[0069] In some practical applications, the position sensor 15 may be a distance sensor. The user may install the distance sensor on the side of the window frame 11 facing the window body 10 . The distance sensor is used to obtain the distance between the window body 10 and the window frame 11 , and then determine the opening state of the window body 10 .

[0070] In other practical applications, the position sensor 15 may be an angle sensor. The user may install the angle sensor at a position corresponding to the rotation axis between the window frame 11 and the window body 10. The angle sensor is used to obtain the rotation angle of the window body 10 and thereby determine the open state of the window body 10.

[0071] Optionally, when the window body 10 is open, the control module can also control the rotation speed of the fan 24 according to the degree of opening of the window body 10, and the rotation speed of the fan 24 is proportional to the degree of opening of the window body 10.

[0072] For example, when the user rotates the window body 10 30° toward the room, the control module controls the fan 24 to operate at a first speed. When the user rotates the window body 10 60° toward the room, the control module controls the fan 24 to operate at a second speed. The first speed is lower than the second speed.

[0073] like Figure 6 As shown, in some embodiments, the fresh air system 20 further includes a grille assembly 13. The grille assembly 13 is rotatably disposed at a position corresponding to the window frame 11 and the fresh air duct 22 to control the wind direction of the fresh air device 21 supplying air to the room.

[0074] Specifically, installing the grille assembly 13 at the corresponding position between the window frame 11 and the fresh air duct 22 can prevent indoor debris from entering the fresh air duct 22, thereby avoiding installation hazards. At the same time, the user can adjust the direction of the air supplied by the fresh air device 21 into the room by rotating the grille assembly 13, thereby simulating natural wind and further improving the user experience.

[0075] like Figure 7 As shown, in some embodiments, the grille assembly 13 includes a vertical grille 131 and a first motor. The vertical grille 131 is vertically disposed at a position corresponding to the window frame 11 and the fresh air duct 22, and is horizontally rotatable. The first motor includes a rotating shaft drivingly connected to the vertical grille 131, and is used to drive the vertical grille 131 to rotate.

[0076] Specifically, the grille assembly 13 may include a plurality of vertical grilles 131, and the plurality of vertical grilles 131 are sequentially rotated in the horizontal direction and arranged on the window frame 11. In this way, the user can rotate the vertical grille 131 to the left or right to allow air to flow into the room to the left or right. In the case where the grille assembly 13 includes a plurality of vertical grilles 131, the fresh air system 20 also includes a first transmission structure. The first motor is respectively driven and connected to the plurality of vertical grilles 131 through the first transmission structure to drive the plurality of vertical grilles 131 to rotate. In this way, the user can control the first motor to drive the vertical grilles 131 to rotate back and forth periodically to sweep the air left and right, further improving the user experience.

[0077] like Figure 8 As shown, in some embodiments, the grille assembly 13 further includes a horizontal grille 132 and a second motor. The horizontal grille 132 is horizontally disposed at a position corresponding to the window frame 11 and the fresh air duct 22, and is vertically rotatable. The second motor includes a rotating shaft drivingly connected to the horizontal grille 132, and is used to drive the horizontal grille 132 to rotate.

[0078] Specifically, the grille assembly 13 may also include a plurality of horizontal grilles 132, and the plurality of horizontal grilles 132 are sequentially rotated in the vertical direction and arranged on the window frame 11. In this way, the user can rotate the horizontal grille 132 upward or downward to allow air to flow upward or downward into the room. In the case where the grille assembly 13 includes a plurality of horizontal grilles 132, the fresh air system 20 also includes a second transmission structure. The second motor is respectively driven and connected to the plurality of horizontal grilles 132 through the second transmission structure to drive the plurality of horizontal grilles 132 to rotate. In this way, the user can control the second motor to drive the vertical grille 131 to rotate back and forth periodically to sweep the air up and down, further improving the user experience.

[0079] like Figures 6 to 8 As shown, optionally, the fresh air system 20 further includes a control panel 14 . The control panel 14 is mounted on a side of the window frame 11 facing the indoor space, and is electrically connected to the fresh air device 21 for controlling the fresh air device 21 .

[0080] Specifically, the control panel 14 is electrically connected to the fan 24 , and the user can control the fan 24 to be turned on or off, as well as the rotation speed of the fan 24 through the control panel 14 .

[0081] It is understandable that after the user controls the fresh air device 21 through the control panel 14 , the control module automatically stops controlling the fresh air device 21 .

[0082] like Figure 6 As shown, in some embodiments, the fresh air duct 22 includes an air outlet communicating with the interior of the room, and the size of the air outlet is smaller than the size of the window frame 11. The fresh air system 20 further includes a windshield 12. The windshield 12 is disposed in the gap between the air outlet of the fresh air duct 22 and the window frame 11.

[0083] Specifically, the windshield 12 is the same size as the window frame 11 and has an opening that is the same size as the air outlet. The air outlet of the fresh air duct 22 is installed in the opening of the windshield 12, connecting the fresh air device 21 with the indoor environment. Thus, the windshield 12 can be installed in the gap between the air outlet of the fresh air duct 22 and the window frame 11, preventing outdoor air from flowing directly into the room when the window body 10 is open.

[0084] Optionally, a sealing structure is provided at a position corresponding to the wind shield 12 and the window frame 11 , and a sealing structure is provided at a position corresponding to the wind shield 12 and the fresh air duct 22 .

[0085] Specifically, a sealing structure is provided at the position corresponding to the wind shield 12 and the window frame 11 to prevent outdoor air from flowing directly into the room through the gap between the wind shield 12 and the window frame 11. Similarly, a sealing structure is provided at the position corresponding to the wind shield 12 and the fresh air duct 22 to prevent outdoor air from flowing directly into the room through the gap between the wind shield 12 and the fresh air duct 22.

[0086] Optionally, the sealing structure may be a sealing strip or a sealant.

[0087] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless expressly required, individual components and functions are optional, and the order of operations may vary. Portions and features of some embodiments may be included in or replace portions and features of other embodiments. The embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
