Abstract

The utility model relates to an electric heating plate, belonging to a special exothermic device for electric cookers. The utility model comprises an electric heating pipe, a seat bottom and a soaking plate. The utility model is characterized in that the electric heating pipe is in a compound wall form; the soaking plate is an aluminium plate; the base is provided with a heat-insulating layer. The utility model solves the problems of most electric heating pipes adopt a ring bend system in the prior art and can not preserve the heat below 500 DEG C, and can work normally below 500 DEG C. The utility model has the advantages of adjustable power, fast warming up speed, uniform temperature and obvious effect. Many groups of the electric heating pipes can be adopted in order to satisfy various electric cookers.

Description

Electric heating plate

A kind of electric heating plate belongs to the special-purpose heater members of electric-heating cooking utensil.

At present, the special-purpose heater members of domestic electric-heating cooking utensil has electrothermal tube cast aluminium formula heat-generating disc, and die casting aluminium plate inlaid electrothermal tube is arranged, and has electrothermal tube casting form such as in aluminum pot or iron pan.Although can play the effect of heating, heating-up temperature is lower than 500 ℃, and complex process, and a heat-generating disc encloses electrothermal tubes with regard to intractable, so power designs is restricted easily with 2.

The purpose of this utility model just is the deficiency at prior art, provide a kind of can be 500 ℃ of following operate as normal, technology is simpler, temperature is even, programming rate is fast, the electric heating plate of adjustable power.

The utility model is realized in the following way:

Whole electric heat-generating disc is made up of electric heating tube, base, soaking plate, it is characterized in that: electric heating tube is a composite shaping formula, and its composite outer wall is last flat circular down, and interior is tubular electric heating, composite shaping electric heating tube is fixed on the base, and the top is the soaking plate that aluminium sheet is made.

The utility model can also be realized in the following way:

The base of electric heating plate is made up of outer cover 6, heat-insulation layer 5, platen 4, and the one side of composite shaping electric heating tube is fixed in the groove of platen 4.

The utility model also can be realized in the following way:

The heat-generating disc profile can also be made various arcs, with supporting uses of family's daily cooking utensil such as pot, kettles.

Fig. 1 is the utility model electric heating plate internal structure schematic diagram.

Fig. 2 is the local amplification view of composite shaping electric heating tube.

The various arcs that Fig. 3 can be made into for the utility model electric heat-generating disc profile.

Fig. 1,2 also is a most preferred embodiment of the present utility model.

Among Fig. 1: the 1st, electrothermal tube, 2 composite shaping sleeve pipes, 3 soaking plate, 4 platens, 5 heat-insulation layers, 6 guard shields.

The utility model is described in further detail below in conjunction with accompanying drawing:

Electrothermal tube adopts composite, outer wall becomes it through shaping and goes up flat circle down, this structure can guarantee that the bottom embeds in the groove of platen preferably, be that the plane has increased the effective contact area with soaking plate because of top again, adopt pure aluminum plate with the cooker contact-making surface in addition, make its heat transferred rapid, evenly, platen is steel, its effect is that electrothermal tube and soaking plate are pressed together, make it reduce the slit as far as possible, heat waste is reduced, the heat efficiency improves greatly, for making its thermal loss slow, below platen, set up heat-insulation layer again, electrothermal tube bend the employing special process, make its handling ease, can make many groups as required, adjustable power.

Compared with prior art, electric hot tray of the present utility model has following advantages:

1, power is adjustable, can be 500 ℃ of lower normal operations;

2, programming rate is fast, and temperature is even, and energy-saving effect is obvious;

3, technology is simple, safe than cast aluminium, reliable;

4, electrothermal tube can adopt many groups as required, satisfies the use of various electric-heating cooking utensils.

Claims

1, a kind of electric heating plate, form by electric heating tube, base, soaking plate, of the present utility model being characterised in that: electric heating tube is a composite shaping formula, its composite outer wall is last flat circular down, interior is tubular electric heating, composite shaping electric heating tube is fixed on the base, and the top is the soaking plate that aluminium sheet is made.

2, according to the described electric heating plate of claim 1, it is characterized in that described base, form that the one side of composite shaping electric heating tube is fixed in the groove of platen 4 by outer cover 6, heat-insulation layer 5, platen 4.
