Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0022] like Figure 1-2 As shown, the ventilation device with fresh air function of the present invention includes a box body 01 and a fan 02:

[0023] The box body 01 has an indoor air inlet (in order to express the fan, the indoor air inlet is not shown in the figure), an indoor air outlet 11, an outdoor air inlet 12, and an outdoor air exhaust port 13. The indoor air inlet is used to let the indoor air enter the box The inner cavity, the indoor air outlet is used to exhaust the air indoors, the outdoor air inlet is used to let the outdoor air enter the inner cavity of the box, and the outdoor air outlet is used to exhaust the outdoor air; the outdoor air inlet and the outdoor air outlet are both passed through the air duct Connect to the outside (as shown in the figure); while the indoor air inlet and indoor air outlet can be connected to an appr...

Abstract

The invention discloses a ventilation device with a fresh air function and belongs to ventilation devices. An existing ventilation device cannot supplement fresh air into space. A box is provided with an indoor air inlet, an indoor air outlet, an outdoor air inlet and an outdoor exhaust opening, a bidirectional draught fan is arranged in an inner cavity of the box, a volute of the draught fan is provided with an air sucking opening exposed in the inner cavity of the box, an indoor side air channel communicating with the indoor air outlet and an outdoor side air channel communicating with the outdoor exhaust opening, the outdoor air inlet communicates with the air sucking opening through the inner cavity of the box, the inner cavity of the box is provided with a rotating air door driven by a position-changing motor, the indoor air inlet and the outdoor air inlet are selectively separated from the air sucking opening through rotating and position changing of the rotating air door so that the separated air inlet cannot feed air into the air sucking opening of the volute of the draught fan, and the air inlet which is not separated can feed air into the air sucking opening of the volute of the draught fan. Thus, the ventilation device can work in a ventilation state or a fresh air state under the assistance of the exhaust direction of the bidirectional draught fan.

Description

technical field [0001] The invention belongs to a ventilation device, in particular to a ventilation device with a fresh air function. Background technique [0002] Most of the existing ventilation devices are an air inlet and an air outlet. The air inlet is connected to the room, and the air outlet is connected to the outside. During work, only the space is ventilated, that is, the air in the space is discharged to the outside. However, when the air in the space is exhausted, fresh air needs to be supplemented into the space, and the existing ventilation device (ventilation fan) does not have such an effect. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defect that the existing ventilation device cannot supply fresh air to the space, and provide a ventilation device with the function of fresh air. [0004] In order to achieve the above object, the ventilation device with ...
