Problems solved by technology

[0004] However, the inventors have found that when the above electric water heater is in use, the water outside the pipeline is difficult to be preheated. The reason is that the heating element is arranged on the upper part of the pipeline, and the hot water heated by the heating element is concentrated inside The top of the tank, it is difficult to form convection with the water at the bottom of the tank

Abstract

The invention discloses an electric water heater, which comprises a liner, a sleeve positioned in the liner, a heating pipe positioned in the sleeve, a water inlet pipe and a water outlet pipe, wherein the sleeve extends between the top and the bottom of the liner; the heating pipe is adjacent to the bottom of the liner; and the top and the bottom of the sleeve are communicated with outer liner space of the sleeve respectively. The invention also discloses the sleeve for the electric water heater. The sleeve for the electric water heater is arranged in the liner provided with the heating pipe at the bottom, wherein the sleeve is sleeved on the heating pipe; one end of the sleeve is adjacent to the bottom of the liner, while the other end is adjacent to the top of the liner; and the sleeve is provided with a water inlet on the sleeve wall at the end adjacent to the bottom of the liner and a water outlet on the sleeve wall at the end adjacent to the top of the liner. The electric water heater achieves the function of water storage and instant heating on the same electric water heater on the basis of simple structure and simple technology.

Description

technical field [0001] The invention relates to an electric water heater, in particular to an electric water heater which not only has the function of preheating water storage, but also has the function of instant heating. Background technique [0002] In order to enable the electric water heater to reach a stable temperature in a short time, the existing electric water heaters usually have an anti-heat loss structure outside the heating tube, such as the medium-temperature water storage type quick-heating system with an anti-mixing heat device disclosed in the Chinese utility model patent specification CN2874345Y. Compensation electric water heater. The cold water enters the inner tank and is heated to medium temperature by the primary heating tube and stored. The medium temperature water flows through the rapid heat compensation heater for rapid heat compensation to achieve the purpose of rapid heat compensation. However, since this type of electric water heater needs to ...
