Abstract: Disclosed is a flow path switching device including: a case including a first nozzle into which fluid is introduced, a second nozzle through which fluid is discharged, a plurality of inner outflow pipes through which fluid supplied from the first nozzle flows, a plurality of inner inflow pipes through which the fluid supplied to the second nozzle flows, and a flow path connection portion in which a space is formed to communicate the plurality of inner outflow pipes with the first nozzle or to communicate the plurality of inner inflow pipes with the second nozzle; a valve rotatably disposed in the space of the flow path connection portion, and having a first chamber connecting one of the plurality of inner inflow pipes and the first nozzle according to placement, and a second chamber connecting one of the plurality of inner outflow pipes and the second nozzle; and a motor disposed in one side of the valve and rotating the valve. Each of the first nozzle, the inner outflow pipe, and the flow path connection portion forms a flow path perpendicular to each other inside. A first chamber hole connecting the first chamber and a nozzle flow path formed inside the first nozzle is formed in the valve. A cross-sectional area of the nozzle flow path is reduced to a size corresponding to the first chamber hole from an inlet portion of the first nozzle towards the flow connection portion.
