[0028] The present invention provides a window-type fresh air fan 10.

[0029] Please refer to Figure 1 to Figure 2 In one embodiment of the present invention, the window-type fresh air fan 10 includes a casing 11, a sound sensor 13, a controller 15 and an audio generator 17. The casing 11 is formed with a accommodating chamber 111 and an isolation chamber 112 that are spaced apart from each other. The isolation chamber 112 is connected to the outdoor environment and is separated from the indoor environment. The sound sensor 13 is arranged in the isolation chamber 112, and the controller 15 and the audio generator 17 are arranged in the accommodating chamber 111. The controller 15 controls the audio generator 17 to emit corresponding noise reduction waves according to the noise audio of the outdoor environment sensed by the sound sensor 13.

[0030] The window-type fresh air fan 10 of the embodiment of the present invention is provided with an isolation chamber 112 which is separated from the indoor environment and connected to the outdoor environment, and a sound sensor 13 is arranged in the isolation chamber 112, so that the sound sensor 13 can sense the noise of the outdoor environment more accurately, and then the controller 15 controls the audio generator 17 to emit corresponding noise reduction waves according to the outdoor environment noise, so that the window-type fresh air fan 10 can achieve the noise reduction function, enriching the function of the window-type fresh air fan 10 and also helping to optimize the indoor environment.

[0031] In this embodiment, the controller 15 obtains the noise data of the external environment through the sound sensor 13, and processes and calculates the noise data of the external environment to obtain the frequency and amplitude corresponding to the noise of the outer ring environment, and then controls the audio generator 17 to emit a noise reduction wave with the same frequency and amplitude as the noise data and a phase difference of 180 degrees, thereby achieving the effect of noise reduction.

[0032] Specifically, the housing 11 includes a shell 113 and a front cover 116. The shell 113 forms a receiving chamber 111 and an isolation chamber 112. The shell 113 is provided with a first opening 114 connecting the receiving chamber 111 with the indoor environment and a second opening 115 connecting the isolation chamber 112 with the outdoor environment. The front cover 116 is movably mounted at the first opening 114. In this way, the front cover 116 is mounted at the first opening 114 to shield the first opening 114, thereby preventing indoor impurities from entering the receiving chamber 111. The controller 15 can also be isolated from the indoor environment to ensure the normal operation of the controller 15. Since the front cover 116 is movably mounted at the first opening 114, when it is necessary to inspect and repair the components in the receiving chamber 111, such as the controller 15 and the audio generator 17, the first opening 114 can be opened by operating the front cover 116 to facilitate the inspection and repair of the components in the receiving chamber 111.

[0033] Preferably, the housing 113 includes a body 1131 and an isolation box 1132 detachably connected to one side of the body 1131, the body 1131 forms the accommodating cavity 111, the isolation box 1132 forms the isolation cavity 112, and the isolation box 1132 is provided with a second opening 115. In this way, the isolation box 1132 is detachably connected to the body 1131, so that the sound sensor 13 in the isolation box 1132 can be easily cleaned, repaired and replaced.

[0034] Furthermore, the isolation box 1132 includes a box body 1133 and a box cover 1134 covering the box body 1133, the box body 1133 forms an isolation chamber 112, the box body 1133 includes a bottom plate 1135 and a side plate 1136 connected to the edge of the bottom plate 1135, the bottom plate 1135 is detachably mounted on one side of the main body 1131, the side plate 1136 is provided with a second opening 115, the box cover 1134 covers the side plate 1136, and a gap is formed between the box cover 1134 and the second opening 115 to connect the second opening 115 and the outdoor environment. In this way, a second opening 115 is opened on the side panel 1136, and the box cover 1134 is covered on the side panel 1136. The second opening 115 is connected to the outdoor environment through the gap between the box cover 1134 and the second opening 115. This structure can ensure the strength of the isolation box 1132 when in use and prevent the isolation box 1132 from being easily cracked or damaged due to the opening of the second opening 115.

[0035] In one embodiment, the top of the front cover 116 is rotatably connected to the top of the housing 113, for example, the front cover 116 and the housing 113 can be connected by a hinge, and the front cover 116 rotates relative to the housing 113 to open or close the first opening 114. In this way, when it is necessary to inspect the components in the accommodating chamber 111, the first opening 114 can be opened by rotating the front cover 116. Moreover, since the window-type fresh air blower 10 is usually installed at the top of the window and is located at a higher position indoors, when it is necessary to open the first opening 114, it is necessary to use a ladder or other aerial work tools. The front cover 116 of the embodiment of the present invention is rotatably installed on the top of the housing 113, so that when it is necessary to open the first opening 114, the first opening 114 can be opened by lifting the front cover 116 upwards. After opening the first opening 114, the front cover 116 is still connected to the housing 113, and there is no need to place the front cover 116 in other positions, which is convenient and quick to operate.

[0036] In another embodiment, the front cover 116 is detachably connected to the housing 113, and the audio generator 17 and the controller 15 are installed on the front cover 116 and placed in the accommodating chamber 111. In this way, when assembling the fresh air blower, the audio generator 17 and the controller 15 can be first installed on the front cover 116, and then the front cover 116 can be assembled to the housing 113, which is convenient for the installation of the fresh air blower. When it is necessary to inspect or repair the audio generator 17 or the controller 15, the front cover 116 can be removed from the housing 113, and the audio generator 17 and the controller 15 can be removed from the housing 113, which is convenient for repairing and replacing the audio generator 17 and the controller 15.

[0037] In some embodiments, the housing 11 further includes an air duct 117 penetrating the accommodating cavity 111, the air duct 117 connects the outdoor environment and the indoor environment, the front cover 116 partially blocks the air outlet 1172 connecting the air duct 117 to the indoor environment, and a plurality of air outlet holes 1162 connecting the air outlet 1172 and the indoor environment are provided at the portion of the front cover 116 blocking the air outlet 1172. In this way, the airflow of the outdoor environment can flow from the air outlet 1172 to the indoor environment through the air duct 117, and the air outlet holes 1162 at the air outlet 1172 can make the airflow in the air duct 117 flow into the indoor environment more evenly, and the user experience is better.

[0038] Preferably, a fan may be provided in the air duct 117 so that the rotation of the fan can drive the air flow in the air duct 117, thereby forming a negative pressure in the air duct 117, drawing outdoor air into the air duct 117 and flowing it into the room, thereby improving the ventilation efficiency.

[0039] For further information, see Figure 3 and Figure 4The window-type fresh air machine 10 also includes a rear cover 18 and a baffle 19. The rear cover 18 is arranged on the outdoor side of the window-type fresh air machine 10. The bottom of the rear cover 18 forms an air inlet 182 connected to the air duct 117. One side of the baffle 19 is connected to the bottom of the outdoor side of the window-type fresh air machine 10 and is arranged to tilt outward and upward. The other side of the baffle 19 is spaced apart from the rear cover 18. The airflow of the outdoor environment flows from the air inlet 182 to the baffle 19, and then enters the air duct 117 from the gap between the baffle 19 and the rear cover 18. The gap between the box cover 1134 and the second opening 115 is connected to the outdoor environment through the air inlet 182. In this way, the baffle 19 can prevent large particles of impurities in the outdoor environment from flowing into the air duct 117 with the airflow, causing the air duct 117 to be blocked or causing damage to the fresh air machine, thereby extending the service life of the window-type fresh air machine 10, and also improving the quality of air flowing into the room, thereby enhancing the user experience.

[0040] In some embodiments, the air duct 117 is disposed in the middle of the accommodating chamber 111, and the audio generator 17 and the controller 15 are disposed in the accommodating chamber 111 on opposite sides of the air duct 117. In this way, this structure can not only realize the arrangement of the air outlet 1172 in the middle to realize the middle air outlet, but also help to reduce the horizontal length of the window-type fresh air machine 10 and save space.

[0041] In some embodiments, the window-type fresh air fan 10 also includes a display screen 12, which is connected to a controller 15. The controller 15 controls the display screen 12 to display noise information of the outdoor environment based on the noise audio of the outdoor environment sensed by the sound sensor 13.

[0042] In this way, the user indoors can understand the noise information of the outdoor environment through the display screen 12. The window-type fresh air blower 10 can also be provided with a temperature sensor and a humidity sensor to detect the humidity and temperature of the indoor environment, and display the temperature and humidity through the display screen 12. In this way, the user can understand the temperature and humidity of the indoor environment more clearly through the display screen 12, and the functions of the window-type fresh air blower 10 are more abundant.

[0043] In some embodiments, the display screen 12 is a touch display screen 12, which receives user operation signals and sends the user operation signals to the controller 15, and the controller 15 controls the audio generator 17 to play the corresponding audio according to the user operation signals. In this way, the audio generator 17 can not only play the role of active noise reduction, but also play music, emit prompt sounds, etc., making the functions of the window-type fresh air blower 10 more abundant. Moreover, the user can also control the window-type fresh air blower 10 to perform other operations through the display screen 12, such as adjusting the fan speed.

[0044] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
