Abstract
The utility model relates to an electric water heater. In an enclosed outer shell, an outer insulating layer, a winding, an inner insulating layer and a framework are arranged from outer side to inner side. The enclosed outer shell is connected with a power cord exteriorly, a bracket which is arranged in the framework is connected with a heating body, radiation fins which are arranged in the heating body are connected with a radiating body, and then, the winding is enclosed by an annular press cover and an insulating seal. As the utility model adopts electromagnetic heating, the utility model has high electric efficiency, large radiating area, rapid heat transfer, electricity saving, safety, small temperature rise gradient and long service life, and the utility model is suitable for heating water with different conditions.
Description
The utility model relates to electric water-heating apparatus.
Commercially available various electric heaters are general colorful with electrothermal tube, vacuum coating constant resistance formula heating technique at present.
This Electric heating has following shortcoming:
1, conversion efficiency is low between electric energy and the heat energy, owing to directly put into water, easily leaks electricity, and its insulating properties and security requirement are higher, and general insulating materials is all heat insulation, so heat-conductive characteristic difference conversion efficiency is low.
2, resistance-type heating because of self-temperature up to 1000 ℃ because it is anxious to heat up, make thermograde excessive, therefore fragile, and influence service life.
3, owing to pottery, plated film resistance wire, resistor disc easily rise and split fragmentation, can therefore electric leakage take place and jeopardize personal safety.
The purpose of this utility model is: provide a kind of by the way of electromagnetic induction heating, economize on electricity, safety, non-damageable electric heater.
It is in the shell of a sealing, to internal layer external insulation layer, coil, inner insulating layer, skeleton is set respectively by skin, connects power line outward; Connect a calandria by several supports in the skeleton; Several cooling fins is set in the calandria connects radiator; Coil is by ring-type gland and insulated enclosure sealing.
The utility model heats calandria by alternating magnetic field owing to adopt the electromagnetic type mode of heating, so the electrical efficiency height, because the area of calandria is than electrothermal tube and the big manyfold of ceramics resistor area, so heat loss through conduction is saved electric energy soon.
Because coil (6) is sealed in the heater, so safety, leakproof, copper conductor need only and constantly just can move reliably.
Because calandria directly places water, and temperature rising gradient is little, self-temperature is only a little more than water, so long service life again.
Accompanying drawing 1 is a front view of the present utility model;
Accompanying drawing 2 is internal organs views of the present utility model.
In the metal shell (1) of a sealing, ecto-entad is provided with external insulation layer (10), coil (6), inner insulating layer (9), skeleton (3) respectively, connects power line (5) outward; Connect a calandria (4) by several supports (7) in the skeleton (3); Several cooling fins (8) is set in the calandria (4) connects radiator (12); Coil (6) is by ring-type gland (2) and insulated enclosure (11) sealing.
After the heater energising, when the magnetic field of area that conductor circuit surrounds changed, its loop produced electric current thus with regard to corresponding generation induced potential.Calandria (4) also produces induced current in alternating magnetic field, it is that the resistance that overcomes itself produces Joule heat when flowing.Its heat is in the inner generation of calandria (4), and the speed of intensification is fast and high, thereby realizes electricity-thermal power transfer efficiently.
The utility model adopts the 220V Alternating Current Power Supply; Frequency: 50HZ; Power output can be by tens of watts-thousands of watts according to different needs; The heating water temperature can reach 100 ℃.
Its shape can be made oblong, streamlined, flat, clavate, tubular and different shape as required.
