Fig. 4 is the structural representation of existing IH rice cooker heater.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1-3 shows the structure of one embodiment of the invention IH rice cooker heater.As Figure 1-3, the heater of this IH rice cooker comprises: pot courage 1, the coil panel 2 that is used for induction heating jar courage 1, and for detection of the temperature probe 3 of pot courage 1 bottom temp, pot courage 1 is comprised of outer courage 1a and the inner bag 1b that removably is placed among the outer courage 1a, coil panel 2 is arranged on the below of outer courage 1a, and temperature probe 3 is installed on the coil panel 2, and contacts with the courage bottom 1a2 of outer courage 1a.
For inner bag 1b, its at least part of zone, courage bottom is made by permeability magnetic material, to realize electromagnetic induction heating.In preferred embodiment, inner bag 1b makes with aluminium, and at the courage bottom of inner bag 1b compound magnetic conductor using layer 1b2.Magnetic conductive material layer 1b2 generates heat under the magnetic fields that coil panel 2 produces, and utilizes the thermal conduction characteristic of aluminium, makes whole inner bag 1b homogeneous heating.Be appreciated that ground, only has a magnetic conductive material layer, more magnetic conductive material layer is perhaps arranged, perhaps in the courage bottom of whole inner bag 1b magnetic conductive material layer is set all, perhaps use the metal magnetic conducting material (as, the stainless steel permeability magnetic material) one-body molded whole inner bag 1b all can cooperate the purpose that reaches electromagnetic induction heating with coil panel 2.
In preferred embodiment, outer courage 1a is constituted by the courage body 1a1 of section of metal magnetic conducting material (such as, stainless steel permeability magnetic material) and the courage bottom 1a2 of devitrified glass material.That devitrified glass has is high temperature resistant, intensity good and the characteristics of good insulating, adopts the devitrified glass material to make the courage bottom 1a2 of outer courage 1a, even adopt the metal temperature probe, also can not conduct the current to pot courage 1, can further improve security.The courage body 1a1 of section of outer courage 1a adopts the metal magnetic conducting material to make, and it is subject to the magnetic fields of coil panel 2 generations and generates heat, and this heat radiation makes inner bag 1b heat, be incubated more even to inner bag 1b.
Be connected the reliable connection of 1a2 with courage in order to guarantee the courage body 1a1 of section, and has a preferably sealing in the junction, can connect in the following ways: the root edge of the courage body 1a1 of section of outer courage 1a is provided with inside annular supporting plate 1a3, annular supporting plate 1a3 is provided with mounting groove 1a4, the courage bottom 1a2 of outer courage 1a is supported on the annular supporting plate 1a3, and by in mounting groove 1a4, playing glue, the joint portion of 1a2 bottom the courage and annular supporting plate 1a3 is sealed and fixes.As shown in Figure 2, be provided with two mounting grooves on the annular supporting plate 1a3, the cross section of annular supporting plate 1a3 is the W font.
Outer courage 1a is not limited to use above-mentioned material.For example, the courage body 1a1 of section of outer courage 1a also can adopt metal non-magnet material or other material to make.Can also adopt by the integrated outer courage 1a of non-magnetic metal material, also can reach the purpose of leaking when avoiding cleaning.
In order to realize the difference effect (boiling effect) of cooking, coil panel 2 comprises support 2a, and is wound on and is flat the first coil 2b and the second coil 2c above this support 2a, and the second coil 2c is arranged on the inside of the first coil 2b, and the two is separated by a distance.Can drive by the first coil 2b is applied different signals with the second coil 2c, induction conduction by inner bag 1b bottom magnetic conductive material layer 1b2, and then outside and the centre of inner bag 1b courage bottom heated respectively, difference boiling effect when realizing the water boiling is namely to centre rolling, laterally rolling or evenly rolling.Also can, the first coil 2b and the second coil 2c series connection (comprising the situation that turns to the first coil 2b and the second coil 2c with the same line) are by a signal driver, when design, by the parameter designing to the first coil 2b and the second coil 2c, reach the boiling effect of hope.
In order more effectively to realize temperature survey, adopted the multi-point temperature measurement technology in the preferred embodiment, namely, adopt a plurality of temperature probes 3, usually can adopt 3 to 6, be used for the temperature of the diverse location of measurement pot courage 1 bottom, whole temperature probes 3 can be arranged between the first coil 2b and the second coil 2c of coil panel 2, also a temperature probe 3 can be set at the center of coil panel 2, and remaining temperature probe 3 be arranged between the first coil 2b and the second coil 2c of coil panel 2.In the preferred embodiment, temperature probe 3 adopts thermistor, is supported on by high temperature resistant silicon rubber base 3a on the support 2a of coil panel 2, makes the courage bottom 1a2 close contact of thermistor and outer courage 1a.
As shown in Figure 4, the coil panel integral body of existing IH rice cooker heater is bowl-shape, and its processing is difficulty.In the present embodiment, coil panel 2 is designed to tabular, is easy to processing.
With above-mentioned any one IH rice cooker heater, from pot body of different profiles and stew lid, electric control gear combination, can consist of different IH rice cookers, wherein, pot body has the accommodating cavity of pot courage 1, and the outer courage 1a of pot courage 1 is packed in the courage accommodating cavity of stewing.
The above only is preferred embodiment of the present invention, and protection scope of the present invention also not only is confined to above-described embodiment, and all technical schemes that belongs under the thinking of the present invention all belong to protection scope of the present invention.Should be pointed out that for those skilled in the art in the some improvements and modifications that do not break away under the principle of the invention prerequisite, these improvements and modifications also should be considered as protection scope of the present invention.
