Disclosed is an air pressure heat storage type water heater, comprising a shell (11), a water storage liner (20), a water inlet device, a water outlet device (63), a heating device (30), a sensing device (40), a circuit control assembly (50) and a parameter control panel. The shell (11) and the liner (20) are nested together to form a double-layer vacuum heat insulation structure, or the space between the shell and the liner is filled with a foam heat-insulation material to form a foam heat-insulation structure so that the heat insulation effect of the water heater can be improved. An air storage cavity (70) is arranged in the water heater. A pressurizing device (71) is pre-mounted in the air storage cavity (70) or can be connected to the air storage cavity for injection of air, so that power can be provided for water discharge in a water using process of the water heater, and the amount of water discharge is increased. In addition, in a water discharging process of the water heater of the present invention, the water inlet device cuts off the communication between the inflow water and the water storage liner (20), and the heating device (30) stops heating synchronously, so it can be guaranteed that cold water and hot water are not mixed during use, and the problems of heat loss due to the mixing of the cold water and the hot water in a water storage cavity (21) and power consumption due to repeated heating are effectively avoided. |
