Quick electric water heater

Abstract

A quick electric water heater comprises a base and a preheating water tank located on the base. An instant heating water tank is arranged in the preheating water tank. A water inflow pipe and a water outflow pipe are arranged on the base. Heating pipes are laid in the instant heating water tank. Water inlets distributed in the circumferential direction of the instant heating water tank are communicated with the preheating water tank. A water inflow joint arranged at the bottom of the preheating water tank is connected with the water inflow pipe. A water drainage pipe extending upwards and downwards is arranged in the instant heating water tank. The bottom of the water drainage pipe penetrates the instant heating water tank and is connected to the water outflow pipe through a water outflow joint located at the bottom of the preheating water tank. The top of the water drainage pipe extends to an opening of the top of the instant heating water tank and communicated with the instant heating water tank and the preheating water tank. By the adoption of the quick electric water heater, hot water can be quickly supplied, hot water outflow efficiency is improved, the heat dissipation area is reduced, and the heat insulation effect of the water heater is better; and the size of the whole water heater is small, the water storage capacity is large, and the appearance is attractive and practical.

Description

technical field [0001] The invention relates to a water heater, in particular to an instant electric water heater. Background technique [0002] The existing pre-mixed electric water heaters usually use a set of preheating electric water heaters and a set of collector electric water heaters in combination, each set includes a water tank, water inlet pipe, water outlet pipe, electric heating element, etc. It is very inconvenient to use. [0003] There is also a kind of pre-mixed heat electric water heater, and the instant hot water tank is arranged in the electric water tank. For example, a constant temperature pre-mixed heat electric water heater disclosed in Chinese patent CN201269620Y includes a pre-heated water tank, an electric heating element, an instant water tank, an outlet The water pipeline and the water inlet pipeline, the instant hot water tank connected up and down is set in the preheat water tank, the electric heating element is set in the instant hot water tan...

AI Technical Summary

Problems solved by technology

[0004] Although the water heater is small in size and can adjust the temperature sensitively, the speed of hot water output is not particularly fast, and the water heater, that is, the hot water tank is located in the preheating water tank, both of which are cylindrical, so installation and disassembly Very inconvenient, and the sealing effect is not very good, it is easy to cause heat loss in the water tank
