Electric boiler device based on utilization of residual energy of elevator, and control method

An electric boiler device based on utilization of residual energy of an elevator, comprising a heat storage module, an electric heating module and a control module electrically connected to one another, wherein

• the heat storage module is configured to convert the residual energy generated by the elevator into heat energy of water for being stored in a process of preheating the electric boiler;
• the electric heating module is configured to perform an electric heating function, and electrically heat preheated water input by the heat storage module to a water supply temperature set by a user, so as to satisfy a hot water requirement from the user;
• the control module is configured to collect and receive water temperatures and water levels of water in the heat storage module and water in the electric heating module, and issue corresponding control instructions according to the water temperature and the water level to control water replenishing or electric heating under different water temperature and water level setting conditions;
• and
• the heat storage module is electrically connected to a tractor.
