Abstract

A heating plate (3) by which a cooker (1) made of non-ferromagnetic material is capable of being heated on an induction cooker, comprises a ferromagnetic fiber heating plate attached to an outer bottom surface of the cooker (1) and a thin circular iron sheet provided on an inner bottom surface of the cooker (1). The ferromagnetic fiber heating plate is cut according to the outer bottom area of the cooker (1), and the size of the thin circular iron sheet is regulated by sleeving thin annular iron sheets with larger diameter.

Description

Description Book Induction Cooker Heating Plate Technical Field

The present invention relates to a device for heating by an induction cooker, by which the cooker of a non-ferromagnetic material can be directly heated by an induction cooker. technical background

At present, adding an iron plate to the bottom of the cookware enables the cookware of non-ferromagnetic material to be heated on the induction cooker. The principle is to use the magnetic field generated by the magnetic coil of the electromagnetic oven to act on the iron plate on the bottom surface of the cookware, so that the iron plate generates eddy current and generates heat. However, this extra iron plate is usually fixed to the bottom of the pot (such as a porcelain pot with an iron plate on the bottom), and the area of the iron plate can only correspond to the size of a pot. This makes it possible to have many non-ferromagnetic materials in the home that cannot be heated by the induction cooker. Summary of the invention

In order to overcome the problem of heating a plurality of non-ferromagnetic cookware by adding an iron plate on the bottom surface of the cookware, the present invention provides two kinds of heating plates under the same concept, so that the cookware of various non-ferromagnetic materials can utilize the same heating plate. Heating on the induction cooker <= technical solution

The technical solution adopted by the present invention to solve the technical problem thereof:

1 Attach a piece of adhesive ferromagnetic fiber plaque to the outer bottom surface of a non-ferromagnetic material cookware heated by an induction cooker. Cut the clipboard according to the size of the outer bottom of the cookware, so that the area of the plate is equivalent to the area of the outer bottom of the cookware. When the non-ferromagnetic material cookware using the apparatus is heated by the induction cooker, the J1 field generated by the induction cooker causes the eddy current to be generated, and the ferromagnetic molecules move at high speed to generate heat. Therefore, the cookware of various non-ferromagnetic materials and different bottom areas can be heated by the same piece of hot plate on the induction cooker.

2 Place a circular iron foil on the inner bottom surface of the non-ferromagnetic material cookware heated by the induction cooker. Then, according to the size of the bottom mask of the cookware, a circular iron sheet is added to the outer periphery of the sheet so that the area of the entire heating plate is equivalent to the bottom area of the cookware. When the non-ferromagnetic material cookware using the device is heated by the induction cooker, the magnetic field generated by the induction cooker causes the heating plate to generate eddy current, and the ferromagnetic molecules move at high speed to generate heat. Therefore, the cookware of various non-ferromagnetic materials and different bottom areas can be heated on the induction cooker by using the same heating plate. The invention has the beneficial effects that various non-ferromagnetic material cookware in the transition stage and special non-ferromagnetic material cookware (such as porcelain pot for stew soup) can be used in the popularization process of the induction cooker. The heating plate is heated on the induction cooker and has a simple structure. DRAWINGS

The invention will now be further described with reference to the drawings and embodiments.

Figure 1 is a general concept diagram.

Fig. 2 is a structural diagram of the first sub-concept embodiment.

Figure 3 is a top plan view of a second sub-concept embodiment.

Figure 4 is a cross-sectional view of the A--A in Figure 3 of the second sub-concept embodiment. detailed description

In Figure 1, place the induction cooker heater plate (3) on the bottom of the non-ferromagnetic cookware (1) and place the entire cookware on the induction cooker heating panel (4). Induction cooker heating plate (3) Under the action of the magnetic coil (5) of the induction cooker, eddy current (2) is generated to generate heat, so as to achieve the purpose of heating the food in the pot.

In Fig. 2, the whole paste board is mainly composed of: an adhesive layer (1) and a ferromagnetic fiber layer (4) which are directly adhered to the outer bottom surface of the cookware. After cutting (2), remove the protective film (3) to bond the outer bottom surface of the cookware for use.

In Figure 3, the limit pin (4) on the center round iron piece (2) is embedded in the peripheral iron ring, and the limit hole (5) on the (6) is fixed in its position. The lifting eye (3) on the center round iron piece (2) can be hooked by the hook (1) to move the center round piece (2). The limit pin (7) on the peripheral iron ring (6) can also be inserted into the limit hole (9) on the larger outer peripheral iron ring (8) to adjust the size of the heating plate. (10) A limit pin on the outer peripheral iron ring (8) of larger diameter.

In Figure 4, the limit pin (4) on the center round iron piece (2) is inserted into the limit hole (5) on the peripheral iron ring (6) to fix its position. The lifting ring (3) on the center round iron piece (2) can be hooked by the hook to move the center round piece (2). The limit 钌 (7) on the peripheral iron ring (6) can also be inserted into the limit hole on the larger outer peripheral iron ring (8) to adjust the size of the heating plate.
