Embodiment Construction

[0013] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0014] The cascaded electromagnetic heating device is composed of a water delivery pipe (1), a heating box (2), a heating plate (3), a temperature sensor (4) and a pressure sensor (5).

[0015] The heating boxes (2) and the heating plates (3) are alternately arranged, and a cascade structure is formed between the heating boxes (2), which increases the water flow distance, facilitates heat transfer, and improves heating efficiency.

[0016] Temperature sensors (4) are installed at the entrance of the first-level heating box (2) and at the outlet of the last-level heating box (2), and pressure sensors (5) are installed at the entrance of the last-level heating box (2). Monitor water temperature and pressure for easy control of water temperature and flow.

[0017] The heating plate (3) is composed of a ferrite core (6), a copper coil (7), a f...

Abstract

The invention provides a cascade electromagnetic heating device, and belongs to the field of electromagnetic heating. The cascade electromagnetic heating device comprises a water conveying pipe, heating boxes, heating plates, temperature sensors and a pressure sensor, wherein the each heating plate is composed of a ferrite core, a copper coil, a ferrite wall, an isolation and thermal insulation layer, a steel sheet wall and a medium-frequency power supply system. The heating boxes and the heating plates are arranged alternately, cascade structures are formed between the heating boxes, the water flowing distance is increased, meanwhile, heat transfer is facilitated, and the heating efficiency is improved. The cascade electromagnetic heating device has the characteristics of being safe to use, high in power and efficiency, short in heating time, simple in structure, and uniform and stable in water temperature, and can be widely applied to heating of the fields of families, hotels and theindustry.

Description

technical field [0001] The invention relates to a heating device, in particular to a cascade intermediate frequency electromagnetic heating device. Background technique [0002] Commonly used heating devices are generally divided into two categories: electric heating devices and gas heating devices. Gas heating devices are prone to poisoning due to user misuse during installation or use. Relatively speaking, electric heating devices are safer. The electric heating device is divided into two types: water storage preheating type and direct heating type. The water storage preheating heating device has low power and high efficiency, but it usually takes a long time to preheat. The direct heating device has high power and can heat in a short time, but the high-power components are not compatible with ordinary household power wiring and watt-hour meters, and because of the short heating time and the influence of water pressure and flow rate, the water temperature is not stable. ...
