Description

Technical Field

[0001] This utility model belongs to the field of ventilation technology, and specifically relates to a wall-mounted exhaust fan. Background Technology

[0002] High-temperature split wall-mounted exhaust fans are a common type of cooling device. When the fan motor drives the blades to rotate at high speed, the blades propel the airflow, creating a high-speed airflow on the exhaust fan's outlet side. This reduces the air pressure at that point, creating a negative pressure zone inside the fan. Under this pressure difference, indoor air is continuously drawn into the fan and exhausted outdoors through the outlet. However, existing wall-mounted exhaust fans suffer from the problem of excessively cold exhaust air during operation in cold weather, such as winter, causing a drop in indoor temperature.

[0003] Therefore, in order to address the problem that existing wall-mounted exhaust fans exhaust excessively cold air and cause a drop in indoor temperature when operating in cold weather such as winter, a new type of wall-mounted exhaust fan is needed. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0025] Example 1:

[0026] A wall-mounted exhaust fan includes an air collector, an impeller 1, a motor 2, and a frame 3. The impeller 1 is fixed to the frame 3 via a bracket for the motor 2. The output end of the motor 2 is connected to the impeller 1. The impeller 1 is located inside the air collector. The air collector is fixed to the frame 3 and has a heating film 4. The air collector includes a duct 5, with a first flared opening 6 and a second flared opening 7 at each end. The first flared opening 6 is fixedly mounted on the frame 3.

[0027] The above structure, by setting a heating film 4 on the air duct 5, increases the temperature of the airflow entering the indoor space through the wall-mounted exhaust fan, preventing the indoor temperature from becoming too low due to exhaust air; by setting flared openings at both ends of the air duct 5, the air inlet end can easily collect airflow, and the air outlet end can easily diffuse hot airflow; and because of the flared openings, the incoming airflow can enter the room along the curvature of the flared openings, reducing noise pollution, and preventing noise pollution caused by the straight edges cutting through the airflow.

[0028] The motor 2 bracket is detachably connected to the frame 3 on the side opposite to the air collector. This detachable connection between the motor 2 bracket and the frame 3 facilitates easy replacement of both components in case of damage.

[0029] The aforementioned motor 2 bracket includes a left bracket 8 and a right bracket 9. Both the left bracket 8 and the right bracket 9 are equipped with connecting gaskets 10, which are detachably connected to the frame 3 by bolts. The connection of the connecting gaskets 10 makes the connection between the motor 2 bracket and the frame 3 more stable and avoids stress concentration, making the connection between the motor 2 bracket and the frame 3 less prone to damage.

[0030] A motor 2 connector is provided between the left bracket 8 and the right bracket 9, and the motor 2 is detachably connected to the motor connector 11. That is, there is a motor connector 11 for placing the motor between the left bracket 8 and the right bracket 9, and the motor is detachably connected to the motor connector 11 by bolts, which is convenient for replacement.

[0031] The frame 3 is provided with a side frame 12, and the side frame 12 has bolt through holes. Bolts can pass through the bolt through holes to detachably connect to the wall. By providing the side frame 12 on the frame 3, the frame 3 is not directly connected to the wall. The side frame 12 has a larger area, avoiding stress concentration. Furthermore, by connecting the side frame 12 to the inner wall of the wall, the wall-mounted exhaust fan can be embedded in the wall, making the connection more stable.

[0032] The heating film 4 wraps around the air duct 5. By wrapping the air duct 5 with the heating film 4, the heating film 4 heats the airflow passing through the air duct 5 from all directions, resulting in a larger heating surface and better heating effect.

[0033] The aforementioned motor 2 is a reversible motor. That is, by controlling the motor output terminal to rotate clockwise or counterclockwise, the impeller 1 rotates in the same direction as the motor output terminal, so that the wall-mounted exhaust fan can be used for exhaust or intake.

[0034] The impeller 1 is located inside the cavity of the air duct 5. That is, the air duct 5 provides space for the impeller 1 to rotate.

[0035] In summary, this wall-mounted exhaust fan features flared ends on both sides of the air collector, facilitating airflow collection at the inlet and heat diffusion at the outlet, thus heating the airflow. The flared design also allows incoming air to follow the curve of the flared opening into the room, reducing noise pollution and preventing noise pollution caused by straight edges cutting through the airflow. By wrapping a heating film 4 around the air collector's duct 5, the film heats the airflow through the duct 5 from all directions, resulting in a larger heating surface and better heating effect. The motor is designed for both forward and reverse rotation, allowing the wall-mounted exhaust fan to perform both exhaust and intake functions. A frame 12 is installed on the frame 3 to avoid stress concentration, and the frame connects to the inner wall of the wall, allowing the wall-mounted exhaust fan to be securely embedded in the wall.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
