Problems solved by technology

This kind of water heater has a large volume, and the cost of manufacturing, transportation, and installation is very high. In addition, although the water storage container is provided with an insulation layer, it cannot achieve absolute insulation after all. The hot water can basically only be stored for one day, which is likely to cause waste of electricity.

Abstract

The invention discloses a directly-heated electric water heater which comprises an insulation heating water pipe, a resistance wire, an insulation water outlet pipe and an insulation water inlet pipe, wherein the resistance wire is installed in the insulation heating water pipe; the two ends of the resistance wire are respectively connected with a live wire and a zero wire which are fixed in the live wire wiring opening and zero wire wiring opening at the two ends of the insulation heating water pipe; the insulation heating water pipe is provided with a water outlet close to one end of the zero wire wiring opening and provided with a water inlet close to one end of the live wire wiring opening; the insulation water inlet pipe is communicated with the water inlet; and the insulation water outlet pipe is communicated with the water outlet. The directly-heated electric water heater disclosed by the invention has the advantages of high heating speed, energy conservation and simple and safe structure.

Description

technical field [0001] The invention relates to a direct heating electric water heater. Background technique [0002] In the current market, the electric water heaters in the kitchen and bathroom appliances in the field of household appliances all adopt the water and electricity separation heating method, that is, the resistance wire of the heating element is installed in a copper tube with a length equivalent to the resistance wire, and the quartz-filled tube is used. The powder method is insulated from the copper pipe. The electric water heater with this heating method does not have a long service life, and it may leak electricity in a short time, causing a short circuit and burning down. The reason is that the copper tube is slender, the filling of quartz powder is uneven, there are thick and thin, and the insulation strength of the thin place is low, and the electricity is easy to break down from here, resulting in leakage. If there are two leaks, there will be a short...
