Quick heating type electric water heater using electrical heated tube with non-metal housing

Abstract

The invention relates to a quick heating type electric water heater using an electrical heated tube with a non-metal housing, which is a quick heating device of heating water when water flows. T housing of the electrical heated tube is made from a non-metal material, the electrical heated tube with lead-out rods (1) at one end or two ends is a straight or blind hole non-metal tube (7) or (8), and the electrical heated tube is mounted therein; the electrical heated tube is a carbon fiber tube or a halogen tube or an electrical heated tube with the non-metal housing or a dry burning electrical heated tube, and the lead-out rods (1) extend out of the tube through a non-metal plug (6); meanwhile, a circuit breaker (12) is mounted in a lower portion at an open end of the non-metal tube (7) or the blind non-metal tube (8); one end of the circuit breaker is two exposed and isolated metal wires and the other end of the circuit breaker is connected to a control element of a control circuit board. When the two metal wires encounter water to be conductive at the same time, the control element is informed, so that the circuit is disconnected.

Description

technical field [0001] The invention relates to a fast-heating electric water heater, and mainly relates to an electric heating tube with a non-metal shell immersed in water used in the electric water heater. Background technique [0002] The existing electric heating tubes used in electric water heaters are 100% tubular electric heating elements produced according to the technical standard JB / T4088-1999 "Tubular Electric Heating Elements for Daily Use" or JB / T2379-1993 "Metal Tubular Electric Heating Elements". The tube is the shell, the alloy heating wire is used as the heating element, and there are lead-out rods at one or both ends, and the dense magnesium oxide powder insulation medium is filled in the metal tube to fix the elements of the heating element; "It is a commonly used electric heating element; This kind of electric heating element with a metal shell is completely immersed in water. After a long time of use, it will form scale, reduce heating efficiency, and c...

[0002] The existing electric heating tubes used in electric water heaters are 100% tubular electric heating elements produced according to the technical standard JB / T4088-1999 "Tubular Electric Heating Elements for Daily Use" or JB / T2379-1993 "Metal Tubular Electric Heating Elements". The tube is the shell, the alloy heating wire is used as the heating element, and there are lead-out rods at one or both ends, and the dense magnesium oxide powder insulation medium is filled in the metal tube to fix the elements of the heating element; "It is a commonly used electric heating element; This kind of metal shell electric heating element is completely immersed in water. After a long time of use, it will form scale, reduce heating efficiency, and corrode breakdown, making the water electrified, which is a problem in the world.
