Abstract

A coffeepot used on an electromagnetic oven includes a pot body (1) and a pot bottom (2). Compound material is used on the pot bottom (2).There is an electromagnetic heatable zone and a fixed zone on the pot bottom. The electromagnetic heatable zone lies on the center of the pot bottom (2) and can be contacted with the electromagnetic oven. The fixed zone lies on the fringe of the pot bottom (2) and is fixed with the pot body (1) hermetically. The electromagnetic heatable zone is composed of an electromagnetic heatable layer (3) and a base layer (4). The electromagnetic heatable layer (3) lies on the outside of the pot bottom (2). The fixed zone is composed of the base layer (4) only.

Description

Coffee pot technology field

The utility model relates to a coffee pot suitable for use on an induction cooker. Background technique

Current coffee makers are generally heated using an open flame or an electric furnace. With the popularity of induction cookers, more and more users are hoping to use coffee makers on induction cookers. The patent No. CN 201039927 discloses a double-bottoming process. He first processes a structure on the lower pot, then puts it into a silicone ring, then presses the aluminum bottom, and finally presses the patterned iron piece. This process is complicated. The high temperature of the die casting will melt the silicone ring. Utility model content

The purpose of the utility model is to provide a coffee maker which is simple in structure, easy to process and produce, convenient to use and stable, and cost.

The utility model uses a composite material negative film, which is composed of aluminum sheet and stainless steel composite, and has various thickness specifications. Because of the stainless iron layer, it can be quickly induced and heated on the induction cooker, and the aluminum layer acts as a normal body. The basic layer. The above composite bottom is applied to the bottom of the lower pot by 4 bar and can be directly placed on the electromagnetic furnace for heating.

This process is low in production cost and easy to produce. DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic view of a finished coffee maker of the present invention, which includes a kettle body 1 . A composite backsheet is used for the bottom of the pot, and a material composed of an aluminum sheet and a stainless steel is used here. The composite backsheet 2 can be formed by stamping to obtain a pot bottom corresponding to the size and shape of the KJ groove, and the backsheet can be provided with reinforcing ribs, and the ribs can have various shapes.

The composite backsheet has a heated zone in contact with the induction cooktop and a fixed zone that is sealed to the kettle body.

The heating zone as shown in Fig. 2 has an electromagnetically heatable layer 3 and a base layer 4. Here, an aluminum sheet is used as a base layer, and a non-ferrous iron is used as an electromagnetically heatable layer. The electromagnetizable layer 3 is located on the outer surface of the bottom of the pot, and the fixed area may have only the base layer 4. For the preferred use of the base layer 4, the stainless iron layer 3 on the outer edge of the composite film is removed to expose the aluminum sheet 4 for its attachment to the kettle body.

As shown in Figures 3 and 4, a recess 5 is formed in the bottom of the lower pot and may also be die-cast to accommodate the securing of the securing zone, the outer wall of the recess being higher than the inner wall. Inserting the composite backsheet 2 into the groove 5, and subjecting the outer wall of the W groove to spin forming, deforming the aluminum under pressure, and fixing the composite backsheet in the W groove to the same body Sealed connection to achieve a double bottoming process.

The utility model has the advantages of simple structure and process, convenient processing and reliable use. The various functional structures and embodiments thereof disclosed in the present invention are embodied and protected by the claims, and any of the teachings according to the drawings and embodiments shown in the present invention fall into the present invention. Among the protected areas.
