Problems solved by technology

But after the heating is stopped, the heat loss rate of the contents is still too fast, which is not suitable for the needs of various people who have high requirements on the heat of the heated contents, especially the heating body made of ferromagnetic material is arranged on the container body The inner surface is not suitable for the needs of those who have higher requirements for chemical reaction, corrosion and sanitation.

Embodiment 1

[0015] The first embodiment of the electromagnetic heating and heat preservation container of the present invention is a pottery pot, which is suitable for an electromagnetic cooker with a flat heating surface; its structure is shown in Figure 1.

[0016] In this embodiment, the pottery body 1 has an opening at the top, and the pottery cover 2 closes the opening of the body 1 to prevent heat loss of the heated content. The side wall and the bottom of the body 1 are made relatively thick, and the heating body 3 made of ferromagnetic material is sandwiched in the bottom of the body 1, and the pottery layer between the heating body 3 and the inside of the pot is relatively much thinner. Due to the relatively poor thermal conductivity of pottery, although the heating time will be longer, the thick side wall is good for heat preservation. After stopping the heating, the residual heat of the heating body 3 can also be supplemented to its content by the thin pottery layer between the...

Embodiment 2

[0018] The structure of the pottery and glass double-layer tank of the second embodiment of the electromagnetic heating heat preservation container of the present invention is shown in FIG. 2 . The ceramic outer cylinder 11 with the top opening and the glass inner cylinder 12 with the top opening are set into a double-layer tank with the top opening. heating body 30 . The ceramic cover 20 is used to close the opening of the container body.

[0019] This embodiment is suitable for use in the inner hole of the spiral induction coil of an induction cooker with an inner cylindrical heating surface, and the contents in the tank are heated from the side wall. The heating surface of the straight cylindrical heating body 30 is large, and the thermal conductivity of the glass inner cylinder 12 is relatively good, and the heating time is short; after the heating is stopped, the residual heat of the heating body 30 is easily replenished to its contents through the glass inner cylinder 1...

Embodiment 3

[0021] The structure of the purple sand and enamel double-layer pot of the third embodiment of the electromagnetic heating heat preservation container of the present invention is shown in FIG. 2 . In this embodiment, an iron heating body 300 with an open top and an enamel layer 120 is embedded on the opening of a purple casserole pot 110 with an open top. The purple casserole 110 and the enamel layer 120 form two parts inside and outside the pot body, and the heating body 300 is hidden in the middle. The purple clay cover 200 is used to close the opening of the purple clay pot 110 .

[0022] This embodiment is suitable for being placed in the sunken heating tank of an induction cooker with a combined heating surface of a plane type and an inner cylindrical surface type, and the contents in the pot are heated from the bottom surface and the side wall. In this embodiment, the heating body 300 is made thicker and has a large heat capacity. The enamel layer 120 has high thermal c...

Abstract

An insulating container with electromagnetic heating function is composed of a main body with dual-layer structure and open top, a cover on said open top of said main body, and a heating body made of ferromagnetic material and arranged between two layers of said main body.

Description

technical field [0001] The invention relates to a container, in particular to a container heated by an electromagnetic oven. technical background [0002] There are many kinds of containers heated by induction cooker. The container body is made of non-ferromagnetic material; the inner or outer surface of the container body is provided with a heating body made of ferromagnetic material, which induces electromagnetic waves to generate eddy current heating. In order to facilitate the addition and access of the heated content, the container body must have an opening open to the outside; in order to achieve heat preservation, it also has a cover to close the opening of the container body; to prevent the heat loss of the heated content. But after the heating is stopped, the heat loss rate of the contents is too fast, which is not suitable for the needs of various people who have high requirements on the heat of the heated contents, especially the heating body made of ferromagnetic...
