detailed description

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

The bi-directional blower fan that can enter the fresh air of the utility model is shown in Fig. 1-3, and it comprises volute 11, the two-way centrifugal wind wheel 12 that is positioned at the volute, the motor that is used to drive two-way centrifugal wind wheel to rotate, and shell has air inlet 13. The indoor side air duct 14 and the outdoor side air duct 15 are equipped with a shielding cover 16 that can cover or open the air inlet for the air inlet, and the shielding cover is driven by a transposition motor. In the installed state, the air inlet faces the indoor side, the indoor side air duct is connected to the indoor side, and the outdoor side air duct is connected to the outdoor side.

As shown in Figure 1, the shielding cover 16 is removed from the air inlet 13 of the two-way fan so that the air inlet is opened, and the two-way centrifugal wind wheel 12 rotates counterclockwise under the drive of the motor, and the air flow enters through the air inlet and is discharged from the indoor side air duct. The two-way fan works in the indoor air circulation mode. If a heating device is arranged on the exhaust path of the fan to the room, the two-way fan works in the heating mode.

As shown in Figure 2, the shielding cover is removed from the air inlet of the two-way fan to open the air inlet, and the two-way centrifugal fan wheel rotates clockwise under the drive of the motor. That is, it works in the ventilation mode, exhausting the indoor airflow to the outside.

As shown in Figure 3, the shielding cover covers the air inlet of the two-way fan, and the two-way centrifugal fan wheel rotates counterclockwise under the drive of the motor, and the air flow enters from the outdoor side air duct and is discharged from the indoor side air duct, so that the outdoor air flows into the room , the two-way fan works in the fresh air mode.

Specifically, the indoor side air ducts and the outdoor side air ducts may be symmetrically arranged left and right.

According to the above-mentioned two-way fan, the heater of the present utility model is shown in Figure 4-5, 6-7, comprises blower fan 01, heating device 02, mask 03, and fan is the two-way blower fan that this utility model claims to protect, and heating device is arranged at blower fan On the path of exhaust to the room (the figure is located in the indoor side air duct 14). When the two-way fans shown in Figures 1-3 above work in the heating, ventilation and fresh air modes respectively, the heater works in the heating, ventilation and fresh air modes respectively.

Specifically, the mask is provided with an outer air inlet 31 corresponding to the air inlet, and the shielding cover can be set on the mask to close or open the outer air inlet (see Figure 4-5). When the shielding cover closes the outer air inlet, the indoor air cannot The outer air inlet enters the air into the air inlet of the fan. When the shielding cover opens the outer air inlet, the indoor air can enter the air inlet from the outer air inlet to the air inlet of the fan, thus realizing the indirect sealing or opening of the air inlet. The shielding cover can also be set on the volute (see Figure 6-7) to close or open the air inlet. The mask is provided with an external air inlet corresponding to the air inlet. When the shielding cover closes the air inlet, the indoor air can be taken in from the outside. It flows to the fan but cannot enter the fan from the air inlet. When the shielding cover opens the air inlet, the indoor air can flow from the outer air inlet to the fan and can enter the fan from the air inlet, thereby directly closing or opening the air inlet.

The shielding cover can be in the shape of multiple flaps (see Figure 4-5, Figure 6-7) assembled on the mask or volute and driven by the transposition motor to cover or open the air inlet; or as a whole A piece of plate-shaped and lifting assembly on the mask or volute, the air inlet is covered or opened by lifting; or a whole plate-shaped and rotating assembly on the mask or volute, the air inlet is covered or opened by rotation wide open.

The ports of the indoor side ducts face sideways to direct the airflow to other locations (other locations on the suspended ceiling) through the ducts. Alternatively, the face mask is provided with a corresponding flow port 32, and the port of the indoor side air duct 14 faces the flow port. In the installed state, the port of the indoor side air duct 14 is located at the same position as the face mask on the suspended ceiling.
