Abstract

Disclosed is a heater-type light-wave electric heating tube installing structure in a solar water heater nonmetal water tank. A hole 9 is formed in a semicircular end face of the upper part of the water tank, a flange cover 11 is arranged above the hole, and the flange cover 11 is provided with a heat exchanger 7 and an injection-type 18 which is used for heating water when the water flows past. Connectors 12 with threads or connectors 12 with flanges are coaxially welded at two sides of the lower part of the water tank 8, a metal casing pipe 19 or a non-metal casing pipe 19 is installed in the inner hole of the connectors 12, a straight-shape electric heating tube 6 or a blind-hole-shape 6 is installed on an inner hole air 20 of the casing pipe 19.

Description

technical field

[0001] The invention relates to a solar water heater, and mainly relates to a water tank structure of the solar water heater. Background technique

[0002] At present, the water tanks of solar hot water tanks are mostly made of stainless steel or metal as the base material, and the inner lining is made of enamel. There are generally no holes on the shaped end cap, or only small holes with a diameter of less than 10 cm; and it is not easy to install electric auxiliary heating, especially for stainless steel water tanks, the edge of the weld will lose chromium and nickel components, and it will last for 1-2 years Pinhole leakage will occur. Contents of the invention

[0003] The purpose of the present invention is to improve the metal water tank of the solar water heater, and apply the light wave electric heating tube to the solar water tank for auxiliary heating.

[0004] Technical measure of the present invention is:

[0005] 1. The solar water heater ta...
