Embodiment Construction

[0018] An embodiment is described below. Among Fig. 1, 1, metal thick pipe (1) is the thick stainless steel garden pipe of 0.5 millimeter of longitudinal length 120 millimeters, transverse section diameter 29 millimeters, and some apertures of diameter 3 millimeters are arranged on the tube wall. The pipe wall is cut longitudinally and then rolled into a cylinder. One side after cutting is placed on the other side, the hoop (4) is set on the outside of the pipe wall, and the adjusting screw (5) adjusts the thickness of the metal outer pipe. Metal capillary (6) is the stainless steel garden pipe of 0.5 millimeter of diameter 10 millimeters of long 110 millimeters in length, and some apertures of diameter 3 millimeters are arranged on the tube wall. Conductive wire (7); be connected with fire wire; The spacer (8) between thick tube and thin tube is made of elastic non-toxic plastic; Water inlet (9) can be directly connected with the tee fitting of water pipe, also can Connect t...

Abstract

The invention discloses an electrically heated double-metal-cylinder device in water. The electrically heated double-metal-cylinder device in water is characterized by comprising a thick metal cylinder and a thin metal cylinder; the thick metal cylinder is connected with a zero line of a power source; the thin metal cylinder is connected with a live wire of the power source; the thin metal cylinder is arranged inside the thick metal cylinder and two ends of the thin metal cylinders cannot be exposed; the two metal cylinders are separated through a relatively insulated divider. When the electrically heated double-metal-cylinder device is thrown into the water, the thin metal cylinder which is connected with the live line surrounds the thick metal cylinder which is connected with the zero line, the water between the two metal cylinders is heated due to electric conduction, the external metal cylinder which is connected with the zero line of the power source is surrounded through the live line, the electric charge is shielded through the external metal cylinder which is connected with the zero line, water outside a heater is always at an uncharged state, and human body electric shock is not caused. The electrically heated double-metal-cylinder device in water is energy saving, environmentally friendly, low in cost and easy to maintain, can be applied to various water heaters, can be manufactured into a rapid water heater by being installed into a plastic casing, connected with an indicating lamp, a water temperature controller and the like and connected onto a T-joint pipe part of a water pipe or connected onto a tap faucet through the water pipe.

Description

Technical field [0001] The invention is a device which uses low-voltage alternating current as an input voltage, is made of two metal cylinders, is put into water and uses electricity to heat water, and belongs to the technical field of low-voltage electrical appliances. Background technique [0002] At present, utilize low-voltage electricity (being the alternating current of 220 volts of daily power supply fluctuations, hereinafter the same) to water heating, the device that directly drops into water, all is the metal heating pipe of various shapes on the market. The heating tube is generally made of metal aluminum, copper or stainless steel. After the resistance wire installed in the tube is energized, the electric energy is converted into heat energy, thereby heating the water. The resistance wire and the metal tube wall are separated by an insulator. There are following deficiencies in use. First, the resistance wire is very hot after being powered on. Once the water a...
