Abstract

A cooking pot with heating elements in its bottom part, on the side of the pot being mounted the controls for the utensil. A detachable pot, with various cooking surface and shape, is able to sit inside the main pot. The lid when put on top of the main pot, can be locked by the lever. The lid handle houses a pressure release mechanism. On the side of the main pot, there is a pressure sensing device which controls the power off and lid lock release mechanism.

Description

SPECIFICATION Electrical cooker This patent registration is a electrical cooking utensil. It have features vis.: instant electrical switch off; keep warm switch; two cooking pressure control setting; slow pressure release control; auto over pressure cut off; lid lock when pressure inside cooker are high. This patent related to the patent application No.
853L085 issurea in London on 17th December 1985 which is own by the same pantentee.
The utensil in this patent application is a cooking pot with a 1500 watt and a 20 watt heating elements on the lower part of the port. A removable cooking part which can be changed to different size and shape of cooking surfface. On the side of the pot there is a pressure measuring device which transmit two control functions: lid locking and heating switch off. The control box at the side of the utensil have two user controls: one push button for cooking pressure selection. And the other turning control for instant switch off; auto control of cooking or pressure cooking; and keep warm switch; this control is spring loaded in "off" position. Two indicater light is also in the control housing. On top of the lid handle there is a dial which control the slow release of cooking pressure.There is also a "re-set" button automatically release the excessive pressure inside the cooker. The power switching is inside the control box. When the push button is depress the spring A'P3 made contact for the power to the heater. The switch is held on by spring B'P3. Another push on the button the spring CIP3 hold the switch "on". The controlling lever from the pressure measuring unit will dislodge the springs holding down the push button and switch off the power. The different distant of spring B, c'P3 from the control lever will cause the power to switch off at different level. The "off" "keep warm" "auto" switch is held by spring D'P3.
which hold against "off" position. When the switch turn to "off" position. The push button turn with the switch and break the spring holding down the push button and the power thus switch off. As soon as the hand leave the switch the spring D1P3 will turn the switch to "auto" position. On "auto" position the power switch function normally (push button).
When the switch turn to "keep warm" position the spring D'P3 change the position it attach to wheel E'P3 and held it at "keep warm" position and switch on the 20 watt "keep warm" heater circuit. When the lid put on top of the cooker and the control lever F2P4 turn to close position. The lid will lock by the extending lever and made the cooker air tight. If the pressure inside the cooker is high. A lever from the pressure measuring unit will lock the lid in "close position". The lever will only release the lock on the lid when the pressure inside the cooker is low. The handle on top of the lid housed the slow pressure release unit and excessive pressure auto release unit.
When the plug G2P4 is raise by the dial control.
The cooking gas is release from the plug hole H3,4 into the housing and escape through many holes on the side of the handle. When excessive pressure is inside the cooker the plug J2P4 will spring up and release the pressure through hole k2P4.
1. A cooking pot "A" with heating elements "B" on the bottom part is- control by switches "SW1 and 22." Attach to the side wall of the pot is pressure sensing unit "C" The pot is afix in the main housing with control pannel "E" and lid lock lever "F" power on indicator "Y" a lid is provided.
2. The pressure sensing unit "C" is make of metal dice "H" its outer diameter is make of thinner zigzaz metal plate "1". When air pressure is apply to one side of the dice, attached to the other side of dice is a pole piece "J" which will move accordingly with the pressure being apply on the other side of dice.
3. As in claim (2) attached to the end of pole piece is a lever "K" pivoted at 2 length and attached to the pole piece at mid point.
4. As in claim (3) one end of the lever can move into the slot of the lid opening ring "L".
The other end of the lever it push free the retaining spring "M" holding down the push buttom.
5. As in claim (1) the control pannel consist of push buttom on/off. Its two level of travel is held down by spring "M", it close the power switch "SW1". The push buttom is movable tangentially with the turning control knob "Z". On the push buttom control rod there is a different width platforms "N" which the spring "M" engage.
6. As in claim (1) the turning control knob "0" with key shaped hole for the push buttom knob to slide through. Attach to the turning control shaft is a wheel "P" through its hole a spring with smooth end is attached.
This wheel operate the "keep warm switch SW2".
7. As in claim (1) the lid lock with shaped holes ring "Q" can slide at distant "R", will operate four locks "S" pivoted at one end, while the other end engage the lid. The whole lid lock mechanism is sealled and fixed atop the main cooker housing.
8. As in claim (1) the lid "G" which can lay flat on main cooker body can be engaged by the protuding bodies "S" when the lid lock is in close position.
9. As in claim (8) the handle of the lid is make of metal with hollow inside connected by tube to the other side of lid cover handle chamber "T". Shaped rubber "U", on one hole a metal plug "V" which can lower and
