Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, a heat pump tobacco baking structure includes a baking room and a heat pump unit.

the baking room is provided with a baking chamber 6, a heating chamber 5 and a fan chamber 8, the heating chamber 5 and the fan chamber 8 are respectively arranged at one side of the baking chamber 6, the fan chamber 6 is arranged at the upper part of the baking chamber 6, and circulating air ducts 7 are respectively arranged between the baking chamber 6 and the fan chamber 8, between the baking chamber 6 and the heating chamber 5 and between the fan chamber 6 and the heating chamber 5;

the heat pump unit is a split heat pump unit with three fixed-frequency parallel compressors and comprises a split heat pump unit 1 and a condenser 2, wherein the split heat pump unit 1 is arranged outside a baking chamber 6, and the condenser 2 is arranged in a heating chamber 5; the fan chamber 8 is provided with a fan 4;
