Exhaust device with refrigeration function and heating function

The invention discloses an exhaust device with the refrigeration function and the heating function, and relates to the technical field of kitchen and bathroom electrical appliances. With the exhaust device with the refrigeration function and the heating function, the technical problem that the kitchen and bathroom electrical appliances in the prior art are narrow in application range is solved. The exhaust device comprises an air duct shell, a main fan, an electric heater and a semiconductor cooler, wherein the main fan, the electric heater and the semiconductor cooler are installed on the airduct shell. The air duct in the air duct shell is partitioned into an exhaust channel and an air blowing channel by a partition plate. The air outlet of the main fan is connected with the exhaust outlet of the air duct shell through the exhaust channel. The air outlet of the main fan is connected with the air supply port of the air duct shell through the air blowing channel. A valve plate is arranged at one end of the pa
