Water tank structure of electric energy, solar energy or air energy water heater

Abstract

The invention relates to a water tank structure of an electric energy, solar energy or air energy water heater, which comprises a water tank, electric heating tubes, an energy accumulating cover or heating water tank, a connecting tube and a check valve and is characterized in that more than one circular or wing-shaped metallic or nonmetallic tubular body (12) is installed on the water tank (1) or flange (13) in a firm welding or mechanical connection mode, wherein each of two ends or one end of each tubular body (12) is opened outwards, an optical wave electric heating tube (4-1) is arranged in each tubular body (12), and the water tank needs to be sealed; the optical wave electric heating tubes (4-1) generate heat radiation after being powered on, so that the metallic or nonmetallic tubular bodies (12) are heated, and the water surrounding the tubular bodies (12) is heated through the heat transfer of tube walls; and simultaneously, more than one common stainless steel electric heating tube or silicon carbide tube (4-2) is arranged in the water tank and does not work when the hot water is released. A section of a vacuum tube heat accumulator is inserted into the water tank of a solar energy water heater; a condenser or metallic tube heat exchanger is arranged in the water tank of an air energy water heater; and for each of the solar energy water heater and the air energy water heater, an electric auxiliary heating device is also arranged in the water tank, i.e. the upper part is provided with a rapid-heating electric heating tube, the lower part is provided with a preheating electric heating tube, the heating water tank can also be manufactured on the flange or other parts, a water pump is connected to an end part, and the check valve is installed at the water outlet of the water pump.

Description

technical field [0001] The invention relates to electric energy, solar energy and air energy water heaters, and mainly relates to the water tank structure of the water heater. Background technique [0002] Existing electric water heaters, solar energy, and air energy auxiliary heating all use ordinary stainless steel electric heating tubes to be completely immersed in water, and the water is charged and discharged when bathing; due to long use time, it will definitely break down and make the water electrified, causing more than 1,000 deaths and injuries in our country every year ; Patent Application No. 200910135082.X describes the structure of using light-wave electric heating tubes. Previously, in the same water heater, only the same electric heating tubes and the same heating method were used, and the scope of application was limited. Contents of the invention [0003] The present invention improves the above-mentioned structure. In the same water tank of electric energ...
