Abstract

The invention discloses an electric water heater. The electric water heater comprises an inner container, a water inlet pipe, a water outlet pipe, a top heating pipe arranged at the top of the inner container, and a bottom heating pipe arranged at the bottom of the inner container, wherein the water inlet pipe and the water outlet pipe are fixedly connected to the inner container, the water inletof the water inlet pipe is located at the bottom of the inner container, the water outlet of the water outlet pipe is located on the upper portion of the inner container, the bottom heating pipe is arranged on the periphery of the water inlet pipe, the top heating pipe is arranged around the water outlet of the water outlet pipe; the electric water heater further comprises an intermediate layer heating pipe arranged in the middle of the inner container, the middle layer heating pipe is arranged above the water inlet of the water inlet pipe; and the pipe surface loading of the top heating pipeis 6W/cm<2>-12W/cm<2>. According to the electric water heater, the top heating pipe with pipe surface loading of 6W/cm<2>-12W/cm<2> is used, because the pipe surface loading of the top heating pipe isrelatively low, the top heating pipe could totally engage in stored water heating of electric water heater, therefore the electric water heater can quickly preheat water in the inner container, and stored water preheating time is greatly shortened. The invention further discloses a control method of the electric water heater.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a storage type electric water heater and a control method thereof. Background technique [0002] Storage-type electric water heaters usually use two heating units, the upper and the lower. The heating unit at the bottom of the electric water heater is a preheating heating unit, which is generally used to preheat the water in the inner tank in autumn and winter when the temperature of the water injected into the inner tank of the water heater is low. The heating unit on the upper part is an instant heating unit, generally, when the water is discharged from the inner tank, the instant heating unit directly heats the outlet water immediately. [0003] However, once the above-mentioned storage type electric water heater is used for preheating treatment by the preheating heating unit, the preheating heating unit will preheat the water in the entire inner tank. If the water con...
