Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking device such as a rice cooker, and an object of the present invention is to reduce discoloration and odor of food cooked in a pot.

The rice is kept warm by the amount of oxygen in the natural air, and the oxygen causes discoloration of the rice and deterioration of the fats and oils contained in the rice, resulting in odor.

The present invention solves the above-mentioned drawbacks, and embodiments of the present invention will now be described with reference to the accompanying drawings.

1 is a main body, and 2 is a lower frame which is attached to the bottom of the main body 1 by curling.

3 is a protective frame, the upper edge of which is fixed to the upper frame 4 with a bushing.

The upper frame 4 is fitted into the upper part of the main body 1, and also has a heat insulating effect so that the heat from the protective frame 3 is transmitted to the main body 1. 5 is a heater for cooking rice, which is placed on the bottom of the protective frame 3;
Heat pot 6 from the bottom.

7 is a center thermostat, which is installed in the center of the rice cooking heater 5.

The center thermostat 7 is made of a ferrite with a Curie point and a magnet, and when the rice is cooked, the ferrite loses its magnetism, and serves to push the lever 8 and turn off the completed contact plate 9. Reference numeral 10 denotes a heat-retaining heater which is wound around the upper part of the protective frame 3.

11 is an inner lid, which is placed on the upper part of the pot 6.

Reference numeral 12 denotes an inner lid packing for increasing the internal pressure inside the pot 6.

Numeral 13 is a valve holder attached to the inner lid 11, and a pressure regulating valve 14 is inserted into the central hole to prevent the pressure inside the pot 6 from rising above a certain pressure.

Reference numeral 15 denotes a cushion rubber for attaching the inner cover to the inner cover 11, and the inner cover 11 can be attached to the outer cover 18 by inserting it into a mounting bracket 17 attached to the heat sink 16.

An outer cover 19 is fitted into the outer cover 18 from the outer periphery inward, and the heat dissipation plate 16 is attached to the outer cover 19 with screws or the like with the outer cover packing 20 sandwiched therebetween. The outer lid packing 20 comes into contact with the upper edge of the pot 6 when the outer lid 18 is placed on the main body 1 to prevent steam leakage. 21 is a handle cover of the handle portion of the outer lid 18.

22 is a hook lever, 23 is a hook lever 22 attached to the outer lid 1
The hook lever shaft 24 is a reversing spring for reversing the hook lever 22. 25 is main body 1
The claw of the hook lever 22 is hooked by a buckle attached to the buckle.

26 is a rotary bearing plate for receiving rotation of the outer lid 18; 27;
is a rotating shaft for jointing the outer cover 18 and the rotating bearing plate 26.

Reference numeral 28 denotes a mist catcher for preventing dew droplets on the inner lid 9 from flowing down onto the floor or the like.

29 Switch button inserted into the tip of the chopper bar 8, 3
0 is a display board for attaching the bar 8, and 31 is a rice cooking lamp.

32 is a display board fixing screw, 33 is a cord reel, 34 is a back plate to which the cord reel 33 is attached, and 35 is a leg attached to the bottom surface of the lower frame 2.

36 is the main body insulation material, 37 is the bottom insulation material, 38 is the heat sink 16
39 is a deoxidizer.

This is Yokawa Masubishi insulation material.

41 is a thermal reed switch (hereinafter referred to as TRS) that plays the role of temperature control during heat retention, 42 is a deoxidizer 39
A connecting pipe 43 between the pot 6 and the pot 6 is a connecting cushion rubber attached to the tip of the connecting pipe 42.

Next, the deoxidizer 39 will be explained based on FIG. 4
4 is a positive electrode made of a material such as copper or nickel.

A lead wire 45 is connected to a negative electrode 46.

The negative electrode 46 is made of carbon material. 47 is a ring pipe.

48 is an electrolytic solution, and a potassium hydroxide solution is used.

49 is an electrolytic cell.

50 and 51 are voltage drop resistors.

52 is a half-wave rectifier diode, 53 is a constant voltage circuit, and 54 is a transformer.

55 is a heat retention lamp, 56 is a stabilizing resistor for the heat retention lamp, 57
is a stabilizing resistor for a rice-cooking lamp.

Next, to explain the operation, when you put rice and water in the pot 6 and press the switch button 29, the center thermostat 7 is turned on via the bar 8, the completed contact plate 9 is closed, the rice cooking heater 5 generates heat, and the rice is cooked. is started.

When the rice is cooked, the temperature at the bottom of the pot 6 rises and reaches the operating point of the center thermostat 7, which starts operating. When the completed contact plate 9 is turned off, the circuit enters a heat-retaining state. When the rice is kept warm, the rice cooking heater 5, the warming heater 10, and the lid heater 38 are connected in parallel, and voltage is also applied to the circuit of the deoxidizing device 39, so that the device starts operating. The deoxidizing device 39
The oxygen in the gas inside the pot 6,
The electrolytic solution 48 in the electrolytic cell 49 is released through the connecting cushion rubber 43 and the connecting pipe 42 . Due to this repeated action of the air battery, the amount of oxygen in the pot 6 is reduced to 1/10th or less. By reducing the amount of oxygen in the pot 6, the discoloration of the rice and the growth of spoilage bacteria are prevented, and the rice can be kept warm for a long time.

As is clear from the above description, according to the present invention, the inside of the pot can be kept in a low oxygen state, preventing browning of the cooked food and the proliferation of bacteria, and allowing the food to be stored for a long time.
