Description

Novel electromagnetic heating type rice draining electric cooker

Technical Field

The invention relates to the field of electric cooker manufacturing, in particular to a novel electromagnetic heating type rice draining electric cooker.

Background

The electric driving mechanism of the valve opening device can act on the relay permanent magnet on the valve opening relay rod, the valve opening magnetic force effect after the valve opening device is electrified is relayed and transmitted by the valve opening relay rod, the lower end of the valve opening relay rod is close to the rice water valve, and the rice water valve is opened by the magnetic attraction force of the valve opening permanent magnet.

The valve opening device is electrified, and magnetic thrust can be acted on the relay permanent magnet of the valve opening relay rod through the lower bottom plate of the pot cover, so that the valve opening relay rod is separated from the suspended initial position and falls down due to gravity, and relay transmission of a valve opening magnetic effect is completed.

The valve opening relay rod falls, the valve opening permanent magnet at the lower end of the valve opening relay rod approaches to the valve permanent magnet on the rice water valve and reaches a sufficient distance, the valve opening permanent magnet generates sufficient magnetic attraction force on the valve permanent magnet, the rice water valve is opened by deviating from the position for closing the rice water hole, rice water in the rice cooker is discharged to the rice water basin independently arranged below through the leakage hole, and the rice water and rice are completely separated.

The rice water valve comprises a valve permanent magnet, a sealing ring and a positioning column, when the rice water valve is placed on the rice water leakage hole according to the self gravity, the outer wall surface of the positioning column and the hole wall of the rice water leakage hole form sliding fit, and the sealing ring is tightly attached to the edge of the rice water leakage hole to form the sealing of the rice water leakage hole.

The valve opening device is arranged in the interlayer inner cavity of the cooker cover, and transmits magnetic force to the valve opening relay rod through the cooker opening of the outer liner cooker by separating the inner bottom plate of the cooker cover and the steam condensate partition plate, so that the valve opening device is completely isolated from water and steam for cooking.

The electric driving mechanism on the valve opening device can be a static structure consisting of an iron core and an electromagnetic coil, and can also be a movable structure consisting of an electromagnet and a permanent magnet for controlling the electromagnet to extend or retract.

Two ends of the control system outputting the valve opening signal can be electrically connected with two wiring terminals of the electromagnetic coil and also can be electrically connected with two wiring terminals of the electromagnet.

The valve opening device is electrified, so that the electromagnetic coil can emit magnetic lines at the end of the iron core; the valve opening device is powered off, and the magnetic force lines disappear.

The valve opening device is electrified, so that the iron core of the electromagnet can drive the permanent magnet fixed on the iron core head to extend out; the valve opening device is powered off, and the permanent magnet retracts.

Rice soup basin and rice cooker get into in proper order via the mouth edge of outer courage pot to place in outer courage pot in, rice soup basin lays on the bottom of outer courage pot through the supporting legs, and rice cooker hangs the last edge of outer courage pot, forms outer courage pot and forms the parcel, and rice cooker is on the upper portion, the positional relation between two parties of rice soup basin.

The electromagnetic heating coil only acts on the outer container pot and does not act on the rice pot, and the rice pot and the rice and water in the rice pot realize cooking and heating by steam generated by boiling of clean water in the outer container pot.

It should be noted that:

the lower bottom plate of the cooker cover, the steam condensation clapboard of the cooker cover, the rice cooker and the guide groove of the valve opening connecting rod are all made of nonmagnetic or weakly magnetic stainless steel, or aluminum and alloy, or copper and alloy materials; the relay permanent magnet, the valve opening permanent magnet and the valve permanent magnet are all high-temperature resistant strong magnets.
