Description

Integral iron casting heat-generating disc

Technical field

The utility model relates to electric cooking appliance electric heater unit, is specifically related to a kind of electric cooking appliance heat-generating disc.

Background technology

The mode of heating of the domestic cookers (as electric cooker, electric pressure cooking saucepan, electric bakeware, electric frying pan etc.) that existing market is popular mainly adopts cast aluminium heat-generating disc and split type cast iron heat-generating disc (embedding electric heating heater element after shaping cast iron heat-generating disc body), but cast aluminium heat-generating disc causes the weak points such as its mutability, heat-insulating property are poor, mechanical performance is strong, service life is short due to the reason on material property; And split type cast iron heat-generating disc embeds heat-generating pipe on the basis of the heat-conducting plate cast, this structure easily causes bound fraction to produce gap, and not only the thermal efficiency is low, but also there will be owing to conducting heat bad and dry combustion method phenomenon that is that cause.

Utility model content

The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and provides that a kind of thermal efficiency is high, long service life, mechanical performance strong, the Integral iron casting heat-generating disc of good heat preservation performance.

The utility model object realizes like this.

A kind of Integral iron casting heat-generating disc, comprise heat-conducting plate and be located at the heat-generating pipe below heat-conducting plate, the described heat-conducting plate back side is provided with heating tube chamber, heat-generating pipe is located in heating tube chamber, heating wall of the lumen is interval with some breach, can be fixed Integral iron casting heat-generating disc by breach in casting process, the heat-generating pipe surface of indentation, there is provided with heat insulating coat, heat-generating pipe two electrode tip is bent outwardly and stretches out in heating tube chamber, the heat-generating pipe surface in knee is provided with heat insulating coat equally, heat insulating coat can play a protective role to heat-generating pipe, prevent when casting because high temperature makes heat-generating pipe damage.

Technique scheme also can be made to the following further improve.

Described heat-generating pipe is looping tube, is installed in heating tube chamber by the mode of casting.

Described Integral iron casting heat-generating disc forms through die casting or spun casting casting.

Compared with prior art, the beneficial effects of the utility model are as follows.

Heat-generating pipe wraps up by the tube chamber that 1, generates heat, and fits completely with heat-generating pipe, and heat is farthest delivered on heat-conducting plate, and heat transference efficiency is high, good heat preservation performance.

2, heat-generating pipe and heating tube chamber are combined as a whole, and there will not be binding site to produce the situations such as gap, long service life.

3, the overall heat-conducting plate of the utility model and heating tube chamber are iron casting, and mechanical strength is high, is not easy to damage.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model sectional view.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described further.

Shown in composition graphs 1 to Fig. 2, embodiment is described in detail: a kind of Integral iron casting heat-generating disc, the heat-generating pipe 2 comprising heat-conducting plate 1 and be located at below heat-conducting plate 1, described heat-conducting plate 1 back side is provided with heating tube chamber 3, heat-generating pipe 2 is located in heating tube chamber 3, heating tube chamber 3 wall is interval with some breach 7, can be fixed by breach 7 pairs of Integral iron casting heat-generating discs in casting process, heat-generating pipe 2 surface at breach 7 place is provided with heat insulating coat 6, heat-generating pipe 2 liang of electrode tips 4 are bent outwardly and protrude from heating tube chamber 3, heat-generating pipe 5 surface in knee is provided with heat insulating coat 6 equally, heat insulating coat 6 can play a protective role to heat-generating pipe 2, prevent Yin Gaowen in casting process from causing heat-generating pipe 2 to damage.

Described heat-generating pipe 2 is looping tube, is installed in heating tube chamber 3 by the mode of casting.
