a ventilation device

technical field

The utility model relates to the technical field of ventilation, in particular to a ventilation device.

Background technique

A ventilation fan is a type of air-conditioning appliance that is driven by a motor to rotate the blades to drive the air flow and exchange indoor and outdoor air, also known as a ventilation fan. The purpose of ventilation is to remove indoor dirty air, adjust temperature, humidity and sensory effects. At present, ventilation fans are widely used in families and public places.

However, the current ventilator will accumulate a lot of dust on the surface after being used for a long time, which needs to be cleaned in time. It is relatively easy to clean the dust on the outer surface of the car, but the dust attached to the louvers is extremely difficult to deal with. Due to the small intervals of the louvers and a certain angle of inclination, it is difficult to manually clean them, and it is also difficult to clean them. The louvers are placed at the air outlet. If too much dust accumulates on them and is blown off by the airflow from the inside of the ventilation fan, it will affect the indoor air quality.

Therefore, for the problem that the louver of the ventilation fan is difficult to clean at present, there is an urgent need for a ventilation device with an easy-to-clean louver.

Utility model content

The purpose of the utility model is to provide a ventilating device which is easy to clean the shutters for the problem that the shutters of the ventilation fan are difficult to clean.

In order to achieve the above object, the technical solution adopted by the utility model is:

A ventilation device, comprising a housing and a fan arranged in the housing, the housing is provided with an air inlet and an air outlet, the air outlet is provided with a louver fan, and a humidifying device is also provided in the housing, through The airflow generated by the fan blows the humidified air to the louvers, which can condense water drops on the louvers, so that when the water drops increase to a certain extent, they can automatically slide down on the louvers, so that Take away the dust on the surface of the blinds to keep the blinds clean. In addition, it can also take away the static electricity on the blinds to avoid damage to the ventilation device due to static electricity on the blinds.

Preferably, the humidifying device is arranged between the air outlet and the fan, so that the humidifying effect can be improved.

Preferably, the air outlet is also provided with a filtering device, which can prevent mosquitoes and other small insects from entering the room through the louvers, and has a certain dust removal function.

Preferably, the louver includes several blades, and the blades are in the shape of an airfoil, so that the windward surface of the louver is an airfoil-shaped curved surface, which is conducive to keeping the louver fan in balance when the airflow blows, avoiding the vibration of the louver fan, and This prevents noise and reduces the risk of damage to the louver due to impact.

Preferably, the outer surface of the blade is coated with a cooling layer, so that the louver can withstand high temperature, which can increase the service life of the louver and reduce the maintenance cost of the ventilation device.

Preferably, the cooling layer is formed by coating with cooling paint.

In summary, due to the adoption of the above-mentioned technical solution, the beneficial effects of the present application are:

1. The louver has a self-cleaning function: the airflow generated by the fan blows the humidified gas to the louver, which can condense water drops on the louver, so that the accumulation of small amounts can increase the water drops to a certain extent Automatically slide down on the blinds at times, so as to take away the dust on the surface of the blinds and keep the blinds clean;

2. Eliminate static electricity: the water droplets formed on the blinds can take away the static electricity on the blinds, so as to avoid damage to the ventilation device due to static electricity in the blinds;

3. Increase the air humidity.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in detail.

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figures 1, 2, and 3, a ventilation device includes a casing 1 and a fan 5 arranged in the casing 1, the fan 5 is driven by a motor, the casing 1 is provided with an air inlet and an air outlet, and the air outlet is provided with The louver fan 2 is also provided with a humidifier 4 inside the housing 1, and the airflow generated by the fan 5 blows the humidified gas to the louver fan 2, which can condense water droplets on the louver fan 2, so that the accumulation of small amount becomes more , it can automatically slide down on the shutter 2 when the water drops increase to a certain extent, so as to take away the dust on the surface of the shutter 2 and keep the shutter 2 clean. The air exchange device is damaged due to static electricity. Further, the humidifying device 4 is arranged between the air outlet and the fan 5, which can better improve the humidifying effect.
