Super-thin electric water heater

Abstract

An ultra-thin electric water heater is composed of water-heating tank composed of the coiled tubes welded together, heating infrared lamp tube installed in the space surrounded by said coiled tubes, autoamtic water pressure switch, AC contactor, power switching switch, electric leakage protector and amperometer. Its advantages are thin thickness, small size, light weight and high safety.

Description

technical field [0001] The invention relates to an electric shower for bathing, in particular to an ultra-thin electric water heater. Background technique [0002] At present, there are many kinds of electric water heaters sold in the domestic market, but whether it is volumetric type or instant heating type, basically the electric heating rod is directly heated in the water to make hot water, so it is impossible to truly achieve the goal in terms of structure. Water and electricity are separated, so the absolute safety of users cannot be guaranteed during use. Commercially available instant water heaters, whether imported or domestic, basically follow this structural form, that is, multiple electric heating rods with a single power of 1.5KW-2KW are installed on a wall with a diameter of 40mm-50mm and a length of 10mm. In the metal (mostly copper) heating drum of about 100mm-150mm, the water flowing through the heating drum is heated by means of cluster heating. Due to the ...

[0002] At present, there are many kinds of electric water heaters sold in the domestic market, but whether it is volumetric type or instant heating type, basically the electric heating rod is directly heated in the water to make hot water, so it is impossible to truly achieve the goal in terms of structure. Water and electricity are separated, so the absolute safety of users cannot be guaranteed during use

Commercially available instant water heaters, whether imported or domestic, basically follow this structural form, that is, multiple electric heating rods with a single power of 1.5KW-2KW are installed on a wall with a diameter of 40mm-50mm and a length of 10mm. In the metal (mostly copper) heating drum of about 100mm-150mm, the water flowing through the heating drum is heated by means of cluster heating. Due to the limited distance flowing through, the length is not enough, and the heating time is not enough, so, although the adopted The power is relatively large, generally above 6KW-8KW. Except that the power of the civilian electric meter (generally single-phase 20A) used by residents in our country is not enough, the flow of hot water produced by it is limited by this restriction. When the water temperature of the water pipe is increased by 20 degrees, the water output is generally less than 3L / min, so it is not very practical, and it is basically at the point where few people care about it in the market

At present, in addition to the above-mentioned characteristics of heating methods, electric water heaters on the market also generally have the characteristics of large volume, heavy weight, and thick thickness.
