Embodiment Construction

[0008] figure 1 and figure 2 Shown, IH electromagnetic rice cooker of the present invention mainly comprises shell 1, pot cover 2, inner container 3, the inductance coil 4 of electromagnetic heater that is contained in inner container 3 sides and below, a temperature sensor probe that is contained in inner container 3 below , another temperature sensor probe installed under the lid 2, an infrared heater installed under the lid 2, buttons and a display screen installed on the lid 2, a computer controller installed in the shell 1, and a power cord . One side of the lid 2 is hinged with the upper edge of the shell 1, and the lock tongue on the other side of the lid 2 extends into the lock on the upper edge of the shell 1. A torsion spring is installed on the hinge shaft between the lid 2 and the shell 1, and the lid 2 After the lock was opened, the lid 2 was turned upwards by 80° by the elastic force of the torsion spring. The shell 1 is made of cold-rolled thin steel plate w...

Abstract

The invention discloses an IH electromagnetic cooker. The IH electromagnetic cooker mainly comprises a shell, a cover, an inner container, inductance coils, arranged on the side faces and the lower portion of the inner container, of an electromagnetic heater, a first temperature sensor probe arranged below the inner container, a second temperature sensor probe arranged below the cover, an infrared ray heater arranged below the cover, buttons arranged on the cover, a display arranged on the cover, a computer controller, an electric heating damp-proof mechanism and a power line, wherein the computer controller, the electric heating damp-proof mechanism and the power line are arranged in the shell. The electromagnetic heater is composed of a silicon rectifier stack, a frequency conversion triode, a single board computer, the inductance coils and an electric fan. The upper side face of a lining made of 201 or 202 stainless steel and the upper side face of the shell are separated through insulation materials, the lower side face and the lower face of the lining made of the 201 or 202 stainless steel and the inductance coils of the electromagnetic heater are separated through the insulation materials, and the insulation materials are formed in the mode that a layer of ceramic fiber or glass fiber braided fabric is wrapped inside a layer of fish paper or plastic boards; a small hole in the center of the lining made of the 201 or 202 stainless steel is internally provided with a microswitch and the first temperature sensor probe.

Description

Technical field: [0001] The invention relates to an IH electromagnetic electric rice cooker. Background technique: [0002] The existing IH electromagnetic rice cooker heats the inner tank in two ways: one is to pass high-frequency alternating current into the inductance coil, and the alternating magnetic field generated heats the radial iron bars, and the radial iron bars transfer heat to the inner tank of the electric cooker, cooking . The other is to pass high-frequency alternating current into the inductance coil, and the alternating magnetic field generated directly heats the 201 or 202 stainless steel inner container of the electric rice cooker and cooks rice. separated by glass. In the first way, the radial iron bars transfer heat to the inner tank of the rice cooker with a small contact area, and the heat transfer speed is slow. The radial iron bars store a large amount of heat and have great thermal inertia; therefore, this heat transfer low efficiency. Since th...
