The present invention relates to a vacuum packaging machine for packaging food in a vacuum packaging film and preserving food in a vacuum so as to prevent the oxidation or spoilage of food and, more particularly, to a vacuum packaging machine for home and vehicle use, which has a combination AC-DC power module enabling the vacuum packaging machine to use the DC power of a vehicle as well as commercial AC power used in homes. The vacuum packaging machine includes an AC input terminal for receiving commercial AC power, an SMPS for converting the commercial AC power received from the AC input terminal into DC power, a DC input terminal for receiving DC power from a vehicle, and a combination AC-DC power module including a controller for receiving the DC power from the SMPS or the DC input terminal and controlling a heater and a vacuum pump. |
