The present disclosure discloses an empty pumping prevention apparatus. A bottom of a water tank is provided with a water outlet, and a temperature sensor is provided proximate the water outlet. After a heater stops heating, a water pumping action is performed; during operation of a water pump, temperature data collected by the temperature sensor is continuously read, and a current slope of temperature drop is calculated; then it is determined whether there is water based on a value of the current slope of temperature drop; and the water pump stops operating when it is determined that there is no water in the water tank.
