NOVELTY - The utility model relates to the technical field of kitchen device, claims a mounting waste heat of a collecting device and a shallow opening grain heater using the same. Including: a heating water tank and a temperature difference generating module, the temperature difference generating module is installed at the bottom of the heating water tank; a graphene layer is arranged between the temperature difference generating module and the bottom of the heating water tank, the graphene plate of the temperature difference generating module and the bottom of the heating water tank are attached to the bottom of the temperature difference generating module; one side of the temperature difference generating module far away from the bottom plate is provided with a plurality of pressing plates, each pressing plate is provided with more than two locating holes; the bottom of the heating water pool is provided with the same number of connecting holes corresponding to the locating holes. The beneficial effects are as follows: the screw passes through the graphene layer, a temperature difference generating module and a pressing plate, the nut on the screwing screw rod fixes the temperature difference generating module on the bottom of the heating water tank, the connection is simple, the fixing is reliable, one generating module is convenient to change when it is damage, and the graphene layer solves the problem that the mounting surface of the temperature difference generating module and the heating water tank is uneven. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a shallow disc opening grain heater.
