Abstract

The utility model discloses a kettle used for the water boiling on an electromagnetic oven, which is composed of a flat bottom liner made of ferromagnetic materials and a cover-shaped shell made of non-ferromagnetic materials. The bottom of the shell is hollow. The utility model can reduce the heat quantity dissipation of the body of the kettle and is not eady to scald people.

Description

A kind of kettle

The utility model is a kind of kettle, particularly a kind ofly constitutes by the flat inner bag of ferrimagnet and the hood-like shell of nonferromugnetic material, the naked sky of its outer casing bottom, can be used for the kettle of electromagnetic oven.

Commercially available electromagnetic oven is a kind of stove and accessory that utilizes electromagnetic inductive heating principle work.The high-frequency magnetic field energy that it produces passes the furnace panel of nonferromugnetic material, makes the cooker (as stainless-steel pan) of the ferrimagnet above it produce eddy current (induced-current), produces heat again.Because the electromagnetic oven magnetic field of sending, can pass through certain thickness nonferromugnetic material or air layer and unattenuated, therefore when the spacing of cooker bottom and furnace panel is no more than 5 millimeters, heat unaffected.Electromagnetic oven is to boil water, the past flat kettles of enamel that use, now flat kettles of stainless steel that use more more.Use the flat kettle of these ferrimagnets to boil water, have heating fast. clean. the advantage of no waste gas.But it exists when to boil water the kettle body very boiling hot, and both dissipated heats easily irons people's defective again.

Known, nonferromugnetic material such as plastics. bamboo wood. the magnetic field induction that potlery tile and mica paper are sent by electromagnetic oven can not.When electromagnetic oven is switched on, these materials are placed on the furnace panel, they can not generate heat.Known, the kind of heat-barrier material is a lot, and certain thickness air layer also can play the heat-insulation and heat-preservation effect.

The purpose of this utility model provides the kettle that can be used for electromagnetic oven that lost less being difficult for of a kind of heat irons the people.

The purpose of this utility model reaches like this: make kettle, constitute by flat inner bag of ferrimagnet and the hood-like shell of nonferromugnetic material that is installed on the inner bag outside, the naked sky of its outer casing bottom, the height of its shell can be higher below 4.8 millimeters than the height of inner bag, the backplate that heat-resisting nonferromugnetic material can be arranged at the bottom of its inner bag

During use, the utility model of adorning water is put on the electromagnetic oven, furnace panel will be passed in the magnetic field that electromagnetic oven produces, and make the heating of ferrimagnet inner bag to boil water.Owing to do not generate heat and heat insulation jacket in the inner bag outside of heating, thereby the utility model heat radiation is slower, also can not iron the people.

The utility model utilizes ferrimagnet inner bag heating, covers on that its outer nonferromugnetic material shell does not generate heat and heat insulation, has reached and has both lacked dissipated heat, can not iron people's purpose again.The utility model can utilize the outstanding difference in height that is higher than shell of inner bag, makes the inner bag after being heated not reach smooth furnace panel and desktop.

Below in conjunction with accompanying drawing the utility model is done concrete the introduction.

Accompanying drawing is the schematic diagram of a kind of embodiment of the present utility model.

With reference to accompanying drawing, present embodiment kettle [1] is by stainless steel inner container [2]. and ceramic package [3] and polycarbonate transparent pot lid [4] are formed.Stainless steel inner container [2] is straight body round barrel shape, 14 centimetres of diameters, and bottom [5] are smooth, and flange [6] is arranged at the top, and there is Hu Zui [7] in the place ahead.Ceramic package [3] is the big little cambered surface cylindrical casing of, and the naked sky in its bottom surface [9], its inwall have the inwardly outstanding circumferential rib [10] of a circle, and there is kettle at its rear [8].During installation,, join along [11] up to the top of inner bag top flange [6] with ceramic package [3] with stainless steel inner container [2] ceramic package [3] of from top to bottom packing into.Being subjected to flange [6] and edge, top [11]. the qualification of inner bag [2] and circumferential rib [10], inner bag [2] is fixed together with shell [3], and heat insulation air layer [12] is arranged between the two.As figure, the length of ceramic package [3] from edge, top [11] to shell feather edge [13], grow 1.8 millimeters than stainless steel inner container [2] flange [6] to the length of bottom [5], when therefore present embodiment kettle [1] was placed on smooth electromagnetic oven panel or the desktop, the bottom [5] of its stainless steel inner container [2] can not contact boiler face or desktop.

When using present embodiment, the kettle [1] of having adorned water is put into the electromagnetic oven energising gets final product.

Claims (3)

1. a kettle is characterized in that kettle constitutes the naked sky of its outer casing bottom by flat inner bag of ferrimagnet and the hood-like shell of nonferromugnetic material that is installed on the inner bag outside.

2. by the described kettle of claim 1, it is characterized in that the height of aspect ratio inner bag of shell is high below 4.8 millimeters.

3. by the described kettle of claim 1, it is characterized in that having at the bottom of the inner bag backplate of heat-resisting nonferromugnetic material.
