Multifunctional ventilating fan

Abstract

A multifunctional ventilating fan comprises a machine body, a panel provided with an air inlet and an air outlet. The machine body includes a first area, a second area, and a third area separated by several partition plates. The first area is provided with a first heat exchanger and a ventilating blower. A exhaust port of the ventilating blower is communicated with the outdoor. The second area is provided with a second heat exchanger and a circulating blower. The third area is provided with a compressor. The air inlet of the panel is communicated with the first area to form a first air path. The air inlet of the panel, the first area, the second area and the air outlet of the panel are communicated in turn to form a second air path. A first valve is provided in the second air path for isolating the first area so that a third air path is formed by the air inlet of the panel, the second area and the air outlet of the panel communicated in turn. The present invention can effect ventilating, dehumidifying, heating, cooling and the like functions.
