Description

Novel composite bottom boiler

Technical field

The utility model belongs to the cooker technical field, refers in particular to novel composite bottom boiler.

Background technology

The atresia composite bottom boiler of being produced at present all is that whole sheet and the bottom of a pan strike-on form, but when being compounded in compound bottom sheet on the bottom of a pan, because the row of the air between the compound bottom sheet and the bottom of a pan is unclean, easy entrained air bubbles in the strike-on process, make the compound bottom sheet and the bottom of a pan compound insecure, easily aliquation, come off.

Summary of the invention

The purpose of this utility model provides compound firm, the novel composite bottom boiler that is difficult for aliquation, comes off in a kind of compound bottom sheet and the bottom of a pan.

The purpose of this utility model is achieved in that

Novel composite bottom boiler, comprise a pot body, on the external bottom of pot, be compounded with composite sheet, described composite sheet is the metal composite sheet, have more than one opening or through hole on the composite sheet, opening or through hole be provided with compound bottom sheet on opening or the composite patch that shape is identical, material is identical of through hole.

Opening on the above-mentioned composite sheet or through hole and composite patch are provided with one or more.

Above-mentioned composite patch and composite sheet are interference fit.

Above-mentioned composite sheet is one or more layers.

The outstanding compared to existing technology advantage of the utility model is:

The composite sheet of the present utility model and the bottom of a pan compound firm is difficult for aliquation, comes off.
