Water storage type electric water heater

Abstract

The invention is suitable for the technical field of electric water heaters, and provides a water storage type electric water heater. The electric water heater includes at least one inner tank and atleast one core heater; the inner tanks are used for storing water; and core heaters are arranged in the inner tanks. Each core heater includes a core heater cover seat, a heating pipe and a core wateroutlet pipe; the bottoms of the core heater cover seats are arranged on the proximal ends at the bottoms of the inner tanks, and are provided with the water inlet holes of multiple core heaters; thetop parts of the core heater cover seats are provided with openings, and extend to the proximal ends on the tops of the inner tanks; the heating pipes are arranged in the core heater cover seats; thecore heater cover seats can limit the direct heating volume of water of the heating pipes; and the head ends of the core water outlet pipes are arranged on the proximal ends in the openings on the tops of the core heater cover seats, and the tail ends of the core water outlet pipes stretch to the bottoms of the inner tanks and are connected to the water outlet of the electric water heater. Thus, the electric water heater can achieve functions that nearly can be opened to use in the case of low energy.

Description

technical field [0001] The invention relates to the technical field of electric water heaters, in particular to a water storage electric water heater. Background technique [0002] In traditional water storage water heaters, electric heating tubes are used to heat the water in the water storage tank, and the stored energy is stored in the water storage water heater due to the relationship of specific heat capacity due to the large water storage capacity. At a certain high temperature, such as 50°C, the thermostat operates to suspend the electric heating tube. When the user starts to use the water storage for bathing, the outflowing hot water will be filled by the inflowing room temperature water. For example, the temperature of the room temperature water is 20 °C, the temperature of the water in the water storage tank will drop, and the thermostat will restart the electric heating tube. When the heat flow rate is faster than the heating rate, the water heater can only mainta...
