Abstract

The invention discloses a phase-change heat-storage energy-saving electric water heater and belongs to the technical field of household appliances. The water heater comprises a shell, an insulating layer, an inner tank, a magnesium rod, a sewage draining exit, a hot water outlet, a cold water inlet, a leakage protection switch, a temperature controller and an electric heating pipe, wherein the insulating layer between the shell and the inner tank is a composite insulating layer which consists of a polyurethane foam heat-preservation layer and a phase-change heat storage layer; the energy saving of a water storage electric water heater is realized by the double insulation of heat storage and heat insulation; the polyurethane foam heat-preservation layer is positioned between the shell and the phase-change heat storage layer which is tightly attached to the outer side of the inner tank; the composite insulating layer is 25 to 45mm thick; and the thickness ratio of the phase-change heat storage layer to the polyurethane foam heat-preservation layer is 0.4 to 0.8. The electric water heater has the advantages of capability of improving the energy saving level in a water storage and heat preservation process and reducing power consumption, high heat utilization ratio, safety and low cost, and is environmentally friendly and convenient for operation.

Description

technical field

[0001] The invention belongs to the technical field of household appliances, in particular to a phase-change heat storage and energy-saving electric water heater. Background technique

[0002] With the increasingly severe energy situation, energy-saving technology has become the focus of competition among major water heater brands. At present, the mainstream electric water heater is water storage water heater, and its energy saving mainly includes two aspects, one is the energy saving in the heating process, and the other is the energy saving in the heat preservation process. The former accounts for a very small proportion of the water heater energy consumption, while the latter accounts for 97 %above. Therefore, the core focus of energy-saving design in the water heater industry is mainly on the innovation of the insulation layer.

[0003] At present, the heat preservation of storage-type electric water heaters mainly relies on polyurethane foam materials ...
