Embodiment Construction

[0011] figure 1 Described is an annular core 5 composed of an outer casing and a control panel (not shown) and a steel strip, a steel sheet or a copper strip tightly surrounded by a steel strip or a copper strip installed in the casing, and a ring core that is evenly wound on the annular magnetic medium core A circular coil is assembled to form an annular iron core spiral wire package 1. The wire pack 1 is equivalent to the primary of a transformer electrically connected to the power supply 4 . Its ring is wound with a helical secondary bobbin 2 relative to the primary of the transformer. The solenoid is a metal conductor hollow tube with a water inlet and a water outlet connected to the water inlet and outlet respectively, and its material can be a low-resistivity conductor material, such as silver, copper, aluminum, titanium and other alloy materials , from the cost considerations can choose copper. Said solenoid tube 2 preferably passes through the center of the annular ...

Abstract

Disclosed is a directly heated electric water heater without water tank, comprising an iron core junior wire packet linked to the power source and a secondary hasp. The iron core is a annular iron core wrapped tightly by metal conductor slice, at last its center has a metal conductor hollow pipe which forms heating load, and water-in end and water-out end of the heating load are separately linked with water-in pipe and water-out pipe. The metal conductor hollow pipe as heating load uses 'skin effect' of metal pipe conductor current assembling on heating load. The invention has low energy cost, fast heating effect, high efficiency and maintains water temperature high safety with only several voltages so that there is no need to think about creepage protective device and antielectricity wall for ensuring safety, and it has solved completely the problems of large volume and long waiting time exist in the present water tank-typed electric water heater.

Description

technical field [0001] The invention relates to an electric water heater. Specifically, it relates to an electromagnetic induction electric water heater. technical background [0002] The electric water heater in the known technology is to preheat the electric heating element in the water tank after insulation treatment, and then through the water pipe nozzle or through a series of water temperature control circuits, scale treatment devices, water pressure breakers, or computer controllers. Control to realize the heating of water. The electric heating element that they adopt all is to directly contact with the water tank water with the energy conversion of resistance heating. Its disadvantages are high power consumption and low thermal efficiency. The water tank occupies a large space, the waiting time for preheating is long, and the water storage capacity of the water tank is limited, which cannot guarantee sufficient hot water flow. Therefore, it is necessary to use a c...
