The present invention provides an airbag type hot air heat insulation device, which includes an airbag unit, a heat insulation unit, a hot air supply unit, a return air pipe and a control unit, wherein an airflow channel is formed inside the airbag unit, and the hot air supply unit communicates with the airflow channel, and the hot air supply unit sends hot air to the airflow channel, thereby heating and insulating the heated object configured with the airbag unit. The return air pipe connects the airbag unit and the hot air supply unit, and the return air pipe connects the end of the path along which the hot air flows along the airflow channel and the air inlet end of the hot air supply unit, and accordingly returns the hot air to the hot air supply unit to improve heating efficiency.
