Quick heating device for water storage type electric water heater

Abstract

The invention discloses a quick heating device for a water storage type electric water heater. The quick heating device comprises a first inner container, a second inner container, a hot water outflow pipe and an electric heating pipe. The second inner container is accommodated in the first inner container, a flange is detachably arranged on the end cover surface of the first inner container, one end of the electric heating pipe is connected to the flange, the other end of the electric heating pipe and a water inflow end of the hot water outflow pipe are inserted in the second inner container so as to form a concentrated heating area, water can obtain large heat energy in a small area within short time, water outflow temperature is increased rapidly, and waiting time is saved. The second inner container is detachably arranged on an inner wall of the first inner container and is further provided with a plurality of convection holes, the delaying effect on water flow can be achieved, the water can continuously flow into the second inner container to be effectively heated, and heating efficiency and temperature rising rate are effectively improved.

Description

technical field [0001] The invention relates to the field of heating devices for electric water heaters, in particular to a rapid heating device for water storage electric water heaters. Background technique [0002] At present, the storage type electric water heater adopts the method of placing a heating tube inside the heating device to directly heat the water to make hot water. Due to the large volume of the inner tank, it often takes a long time for the heating tube to heat the water to a suitable temperature. The heating time is insufficient, and the heating efficiency and temperature rise capacity are insufficient. If a low-power heating tube is used, the heating time will be longer. If high-power heating is used, the requirements for the user's power consumption environment are relatively high. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a water storage type electric water heater rapid heating device, th...
