Abstract
A vending machine with selectable internal heating and internal cooling functions includes a cabinet and a heat transmitting system. The cabinet includes a heat source and a goods storage space. The heat transmitting system includes a first air inlet tube, a second air inlet tube, an air outlet tube, and a gas valve. The first air inlet tube connects the heat source to the gas valve. The second air inlet tube connects the goods storage space to the gas valve. The air outlet tube connects the gas valve to the outside of the vending machine. The gas valve can connect the first gas inlet tube to the second gas inlet tube to heat the goods storage space using heat generated by the heat source, or can connect the first gas inlet tube to the gas outlet tube to dissipate heat generated by the heat source.
