The kitchen extractor hood (110) is provided with means (38) for generating a first flow (A, B) of a gaseous mixture taken from the internal environment (51) in which the hood (110) is located and releasing it into the external environment (52). The hood (110) is also provided with means (28) for generating a second flow (C, D) of a gaseous mixture taken from the external environment (52) and/or from the internal environment (51) and releasing it into the internal environment (51), as well as with means (10) for recovering part of the thermal energy contained in the first flow (A, B) and transferring it to the second flow (C, D). The means (10) used to recover thermal energy comprise a recovery device (14) comprising in turn a heat exchanger of the heat pipe type (16), featuring an evaporation section (14E) dealing with the first flow (A, B) and a condensation section (14C) dealing with the second flow (C, D). |
