Problems solved by technology

[0002] Existing electric water heaters, solar water heaters, air energy heat pump water heaters, electric heating boilers, central air-conditioning electric auxiliary heaters, electric steam cabinets, and electric water boilers generally use metal tubes with electric heating wires, and use magnesium oxide powder to connect the electric heating wires and metal pipes. Separate the tube wall, use magnesium oxide to form an insulating layer, and make an electric heating tube, and completely immerse the electric heating tube in water to heat the water. After a long time, the metal tube wall will corrode and break down, and the water will be charged; Chinese patent ZL200420020380. 7 and ZL200920185149.6 use far-infrared tubes and install them in water to heat the water directly through infrared radiation. This structure is difficult to seal. When the glass of the heating tube expands and contracts with heat and is damaged, the water will be charged, which may cause personal injury

Abstract

The invention relates to a water heating device, which consists of a metal tube of which one end is closed and the other end is opened, a flange or a connecting piece with external threads, an electric heating tube and an installation cushion of a heat-insulating electric heating tube, wherein the electric heating tube is arranged in the metal tube of which one end is closed and the other end is opened; after the water heating device is energized and operates, the electric heating tube can be subjected to dry combustion in air to generate infrared light waves, so that the metal tube which wraps the electric heating tube by air heating is arranged in water to separate the electric heating tube from the water, so after the metal tube absorbs heat, the water outside the metal tube can be heated by heat conduction. The water heating device can be applied to electric water heaters, solar water heaters, air energy heat pump water heaters, electric heating boilers, central air-conditioning electric auxiliary heaters, electric heating steam cabinets and electric heating water boilers and is used for heating the water.
