Energy-saving electric iron employing electromagnetic heating

Abstract

The invention discloses a safe and energy-saving electric iron which is particularly applicable to use places with requirements on energy saving and safety. The electric iron comprises a circuit part, an equipment casing and a bottom plate (100), wherein the bottom plate (100) consists of an electromagnetic power output coil (102), an insulating base (101) and a heating plate (103); and the heating plate (103) is made of metal material with magnetic conductivity and metal material with high heat conductivity, a small amount of material is used for manufacturing the heating plate, so that the heating plate has smaller thermal capacity, and the effects of saving energy and reducing cost are realized. The temperature of the electric iron is adjustable, and the electric iron is controlled by an automatic control circuit to stably operate within the preset temperature. The working bottom plate of the electric iron is completely isolated from the mains supply by the insulating base (101), and the safety on power utilization is guaranteed. A tickle-type microswitch is arranged on an operating handle, and a user can enable the electric iron to operate by slightly holding the handle and enable the electric iron to stop heating by loosening the handle. The electric iron also can be used for wetting clothes by spraying water and is convenient to use.

Description

technical field [0001] The invention relates to an electric iron for ironing clothes, in particular to an electric iron with electromagnetic heating function required for energy saving. Background technique [0002] An electric iron is an electrical device for flattening clothes, and its power is generally between 300-1000W. Its types can be divided into: ordinary type, temperature adjustment type, steam spray type and so on. [0003] One of the characteristics of the commonly used electric irons at present is the heat storage function. The steam spray type needs to heat the water to a certain temperature before spraying can work. The non-steam spray type has a metal base plate that needs to be heated, and the floor must be heated to a certain temperature. It can only work after a certain temperature; another feature is that during the interval of ironing clothes, the electric iron should be placed upright, or placed on a special electric iron stand, so as not to burn the c...

Problems solved by technology

[0004] The preheating and intermittent states of these electric irons also produce a large amount of heat dissipation, which will generate a large waste of electric energy; on the other hand, electric irons basically use insulating materials to heat the water body of the steam spray type and the metal soleplate of the non-steam spray type , due to the relatively low thermal conductivity of insulating materials, resulting in low heat transfer efficiency, and the quality and aging of insulating materials will also pose a certain threat to the personal safety of users

[0005] The "wireless high-frequency electromagnetic iron" invented by Zhao Mingzhen and others with the application number of 91214875.6 is somewhat close to this patent in terms of power supply. It solves some problems in the safety of electricity in use, but still has a steam spray type iron. The problem of the electric iron, and at the same time, a new problem that needs to be frequently heated for the heat storage body, so that the ironing temperature fluctuates constantly
