The utility model provides a multifunctional energy-saving type hot pump incubator, the structure of the utility model is characterized in that one end of a condenser arranged in the incubator body is connected with gas discharge opening of hot pump compressor, the other end of the condenser is connected with a filter, a throttling component, an evaporator, and a gas-liquid separator, the other end of the gas-liquid separator is connected with air absorption opening of the compressor to form a closed hot pump refrigerating/ heating loop. When the incubator is operated, the condenser releases the heat to warm up in the incubator; the evaporator absorbs heat to obtain cold amount for lowering temperature of egg house and poultry house. Egg tray shelf is removed and can become a multifunctional energy-saving hot pump dryer. Adopting the incubator made by hot pump technique, the energy-saving efficiency can be between 60 percent and 75 percent, therefore the utility model has obvious energy-saving effect.
