[0033] Please refer to Figures 1 to 5 The utility model provides a ventilation fan that can be installed in both ceiling and window styles, including a frame 1, a panel 2, a fan 3, an air guide plate 4 and a mounting ring 5;

[0034] The frame body 1 is provided with a housing cavity 10, and the side wall of the frame body 1 is provided with an air outlet 11 communicating with the housing cavity 10; the fan 3 is installed in the housing cavity 10, and the fan 3 is eccentrically arranged in the housing cavity 10, and the fan 3 is located on the side of the housing cavity 10 close to the air outlet 11; the panel 2 is detachably installed at the opening of the housing cavity 10, and the panel 2 is provided with an air inlet 20; the frame body 1 is provided with a flange 12 at the opening of the housing cavity 10;

[0035] The air guide plate 4 is detachably mounted on the outer side of the air outlet 11 and is detachably connected to the flange 12;

[0036] Alternatively, the mounting ring 5 is sleeved on the outer circumference of the frame 1 , and the flange 12 and the mounting ring 5 cooperate with each other and are tightly against the edge of the ventilation fan mounting hole.

[0037] The ventilation fan is provided with a frame 1, a panel 2, a fan 3, an air guide plate 4 and a mounting ring 5. By providing the air guide plate 4 and the mounting ring 5, two different mounting structures are integrated. The assembly methods of the air guide plate 4 and the mounting ring 5 do not interfere with each other. The fan 3 is eccentrically arranged in the accommodating cavity 10 to ensure that the fan 3 has sufficient pressure when the ventilation fan is installed in a ceiling-mounted manner. At the same time, it also ensures the air volume of the fan 3 when the ventilation fan is installed in a ceiling-mounted manner, so that the fan can maintain its original performance regardless of whether it is installed in a ceiling-mounted manner or in a window-mounted manner. When installing in a ceiling-mounted manner, select the air guide plate 4, and when installing in a window-mounted manner, select the mounting ring 5.

[0038] The above structure enriches the installation methods of the ventilation fan, taking into account both ceiling installation and window installation. Customers can choose the installation method of the ventilation fan by themselves.

[0039] Specifically, the air guide plate 4 includes a connecting arc plate 41, an arc plate 42 and an air outlet port 43;

[0040] One side of the arc plate 42 along the Y-axis direction is connected to the connecting arc plate 41; the other side of the arc plate 42 along the Y-axis direction is provided with a first enclosure 421; both sides of the arc plate 42 along the X-axis direction are provided with a second enclosure 422; the air outlet interface 43 is provided on the side wall of the arc plate 42; the flange 12 is provided with a groove 121 adapted to the connecting arc plate 41; the curvature of the arc plate 42 is adapted to the side wall of the frame 1;

[0041] When performing ceiling installation, the connecting arc plate 41 is embedded in the groove 121 and is detachably connected to the flange 12; the outer side of the frame 1, the inner side of the first enclosure 421, the inner side of the second enclosure 422, the inner side of the arc plate 42 and the inner wall of the air outlet interface 43 cooperate to form an air guide cavity; the air inlet 20 is connected to the outside through the air guide cavity.

[0042] When the ceiling is installed, the flange 12 is provided with a groove 121 adapted to the connecting arc plate 41. When the ceiling is installed, the connecting arc plate 41 is embedded in the groove 121, making the assembly more compact. In a specific embodiment of the utility model, the flange 12 and the connecting arc plate 41 are fixedly connected by screws.

[0043] The air guide plate 4 plays the role of air guidance, so that the air can continue to be discharged in a horizontal direction after being exhausted from the air inlet 20. In a specific embodiment of the utility model, the air outlet interface 43 is connected to a hose, and the hose then guides the air out.

[0044] Specifically, a slide groove 13 whose position matches that of the second enclosure 422 is provided on the outer side of the frame body 1 , and the second enclosure 422 is slidably assembled in the slide groove 13 on the corresponding side.

[0045] With the above structure, when the ceiling is installed, the air guide plate 4 is slidably assembled with the slide groove 13 through the second enclosure plates 422 on both sides, and the connecting arc plate 41 is embedded in the groove 121. With the above structure, the assembly is tighter, and an assembly gap is avoided between the frame 1 and the first enclosure plate 421 or between the frame 1 and the second enclosure plate 422, which affects the exhaust efficiency of the ventilation fan and reduces the exhaust performance of the ventilation fan.

[0046] When performing a suspended ceiling installation, after the air outlet interface 43 is connected to the hose, the flange 12 is fixed to the indoor side of the ceiling by screws; then the slide groove 13 of the frame 1 and the second enclosure 422 on both sides of the air guide plate 4 are slidably assembled, and the connecting arc plate 41 is embedded in the groove 121; then, the flange 12 is connected to the connecting arc plate 41 by screws; finally, the panel 2 is covered at the opening of the accommodating cavity 10.

[0047] Preferably, the air outlet interface 43 is provided with a check valve 431. With the above structure, the air can only be discharged from the accommodating chamber 10, avoiding the backflow of the discharged air and ensuring the normal operation of the pipeline system. At the same time, it can also prevent small animals from entering the ventilation fan, causing the ventilation fan to malfunction.

[0048] Specifically, the outer periphery of the frame body 1 is provided with intermittent threads 14 , the inner side of the mounting ring 5 is provided with connecting threads matched with the intermittent threads 14 , and the frame body 1 and the mounting ring 5 are threadedly connected.

[0049] In a specific embodiment of the utility model, the mounting ring 5 and the frame 1 are connected by threads. When performing window installation, the frame 1 is passed through the ventilation fan installation hole on the window, and then the mounting ring 5 and the frame 1 are threadedly connected, and the mounting ring 5 is tightened so that the flange 12 and the mounting ring 5 are tightly against the edge of the ventilation fan installation hole, and finally, the panel 2 is covered at the opening of the accommodating cavity 10. The above structure is simple and firmly connected. While ensuring the stable installation of the ventilation fan, the difficulty of installation and disassembly is reduced, and it is convenient for the staff to disassemble after installation.

[0050] Furthermore, the fan 3 includes a motor mounting plate 31, a motor 32, a fan impeller 33 and an air inlet plate 34, the motor mounting plate 31 is installed on the bottom of the accommodating chamber 10, the motor 32 is arranged on the motor mounting plate 31, the fan impeller 33 is transmission-connected with the rotating end of the motor 32, the air inlet plate 34 is arranged at the proximal end of the opening end of the accommodating chamber 10, and the air inlet plate 34 is provided with an air inlet through hole 341; the rotating axis of the fan impeller 33 does not coincide with the axis of the frame 1, and is located on the side of the accommodating chamber 10 close to the air outlet 11.

[0051] The fan 3 can refer to the existing ventilation fan structure, and the motor 32 is used to drive the fan impeller 33 to rotate with the axis of the rotating end of the motor 32 as the rotating axis, thereby driving the air flow, so that the air enters the accommodating chamber 10 from the air inlet 20, and then discharges the accommodating chamber 10 from the air outlet 11. The motor mounting plate 31 cooperates with the air inlet plate 34 to limit the position of the fan impeller 33 and the motor 32, and the motor mounting plate 31 provides an installation position for the motor 32, so that the motor 32 is fixed in the accommodating chamber 10.

[0052] Furthermore, the fan 3 also includes a wiring cover 35 and a power board 36. The air inlet plate 34 is provided with a power board installation station. The power board 36 is installed at the power board installation station. The power board 36 is electrically connected to the motor 32. The wiring cover 35 is provided at the power board installation station.

[0053] The power board 36 is connected to the outside through a line, and the power board 36 is used to control the opening or closing of the fan 3. With the above structure, the space is reasonably utilized and the volume of the fan 3 is reduced.

[0054] Preferably, the outer wall of the frame 1 is provided with a wire groove 15. When the ceiling is installed, one side of the flange of the frame 1 is flat with the wall, and the power line is led down from the top. Therefore, after the fan lead is led out from the inside, the lead can be led to the top along the wire groove on the surface of the frame for wiring, avoiding interference during the fan installation and affecting the appearance.

[0055] Optionally, the air outlet 11 is provided with a grille 111. Since the ventilation fan adopts a centrifugal impeller, the air inlet direction and the air outlet direction are at a 90-degree relationship. In order to prevent birds or mice from entering, the ventilation fan is provided with a grille 111 at the air outlet to prevent small animals from entering the ventilation fan and causing the ventilation fan to malfunction. There is no need to install a protective cover for rain and bird protection, which can save production costs.

[0056] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementations of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
