Description

  Like the conventional rice cooker, the rice cooker body case was fixed with a high-pressure pan with a pressure-resistant hook stop around the upper part, and the rice cooker body case was placed on the upper part of the rice cooker body case via a vertically openable hinge. Attach a high-pressure pan lid with a pressure-resistant hook stop around the vertical open / close rice cooker body lid so that it can rotate freely with the horizontal rotation mounting means. Rotate the pressure cooker lid about 30 degrees horizontally to fix the pressure-resistant hook and cook the rice with high pressure and high temperature. Then, return the high pressure cooker lid to about 30 degrees horizontally and keep it warm. Similarly, the present invention relates to an eco-high pressure rice cooker that can open and close the rice cooker body lid freely.

Some conventional rice cookers cook rice by applying pressure to the inside of the rice cooker (see, for example, Patent Document 1).
In addition, there is a rice cooker that pressurizes rice after repeating negative pressure and normal pressure to infiltrate moisture into rice (see, for example, Non-Patent Document 1).
However, the rice cooking pressure (absolute pressure 2.44 atm), which is desirable for cooking extremely delicious rice, cannot be raised to a rice cooking temperature of 128 ° C., and cannot withstand high pressure.
JP 2008-055089 A “TOSHIBA Cookware Catalog 2008” Toshiba Home Appliance Co., Ltd., 2008 p. 1.2.3.4.5.6

  Nowadays there are many gourmets who are very particular about rice due to the gourmet boom, especially in the showroom where the commercial pressure rice cookers are lined up with special ugly words such as the feeling of stickiness of white rice, crunchiness, texture, rice grain gloss, rice taste, etc. If the absolute pressure of 1.4 atm (gauge pressure of 0.4 atm) is purchased and the rice cooking is tasted, the low pressure side absolute pressure of 1.68 atm (gauge pressure of 0. It was not as good as the rice cooked at 68 atm.

By the way, my home usually cooks rice on the high pressure side of the pressure cooker, but the rice cooking pressure is 2.44 atm (gauge pressure 1.44 atm) and the rice is cooked in a pressure cooker with a cooking temperature of 128 ° C. Rice is very inconvenient because it cannot be cooked unless it is much more delicious than a commercially available pressure cooker.

Commercial rice cooker pressure (gauge pressure) 0.4 atm <my rice cooking pressure (gauge pressure) 1.44 atm. About 3.6 times the pressure of rice in commercial pressure rice cooker is the rice cooking pressure, rice cooking temperature It was low.
The patent document 1 and the non-patent document 1 have a defect that they cannot be raised to the proper pressure and proper temperature for rice cooking.
When the pan diameter is 21 cm, when the internal pressure is 1.4 atm and the atmospheric pressure is 1 atm, a force of about 140 kg is applied to the lid and pan (this force is still large in the high and low pressure region) It is the limit of hinge and lid opening prevention mechanism of rice cooker.
Also, when the absolute pressure is 2.44 atm and the atmospheric pressure is 1 atm, a force of about 500 kg is applied to the lid and pan, so the pressure-resistant latch structure like the present invention is safe and optimal for the pressure cooker and pressure pan lid. is there.

    The problem to be solved is that delicious rice can be cooked by raising the rice cooking pressure and temperature, but the pressure and temperature suitable for extreme rice cooking cannot be raised with the general commercially available pressure cooker or the structure of the prior art However, at present, rice grains do not become alpha and general commercial rice, especially old rice, etc., becomes rice.

    In the present invention, in order to solve the above-mentioned problems, the rice cooker and the rice cooker lid are simply pressed with a lid between the pan and the lid like the conventional commercial pressure rice cooker, or the conventional technique is a weak latch. Rather than stopping the pressure cooker, the pressure cooker is applied around the top of the pressure cooker and around the pressure cooker lid in six places to ensure a safe structure that can withstand high internal pressure (2.44 atm absolute pressure) and to be easy to handle. The high pressure pan lid 3 is attached to the center of the vertically openable open / close rice cooker main body lid 1b that freely opens and closes by the high pressure pan lid horizontal freely rotating attachment means 6 which is a feature of the present invention, and about 30 in the horizontal direction during rice cooking. Rotate pressure-resistant latches and rotate the other 30 degrees horizontally and release the pressure-resistant latches, and open and close the vertically openable rice cooker body lid 1b in the same manner as an ordinary rice cooker to make the rice ready for cooking. .

  The high pressure pan lid horizontal rotation mounting means 6 has a space in which a pressure adjusting means weight valve 9a is provided, and the mounting state of the high pressure pan lid 3 is also a stable large-diameter inner hollow shape. The pressure cooker lid horizontal rotation mounting means set screw 6a can be a one-touch screw-in type.

  Further, the internal pressure of the high pressure cooker 2 is 2.44 atm (gauge pressure 1.44 atm), and the force applied to the high pressure cooker lid 3 and the high pressure cooker 2 is about 500 kg. Only the pressure cooker pressure-resistant latch 4, the packing 13, and the high-pressure cooker lid pressure-resistant latch 5 of the high pressure cooker lid 3, and the rice cooker body case 1 a, the vertically openable rice cooker body lid 1 b, and the rice cooker The rice cooker body lid vertical open / close hinge 11 provided at the rear upper part of the cooker body case 1a and the rear part of the vertically openable rice cooker body lid 1b, the front upper part of the rice cooker body case 1a, and the vertically openable rice cooker body The rice cooker body lid opening mechanism (not shown) provided at the front of the lid 1b is not applied at all.

・ When cooking rice, the pressure inside the pan is 2.44 atm absolute (gauge pressure 1.44 atm), and the cooking temperature is 128 ° C.
In order to boil and stir the cooked rice, the steam is blown out from the pressure adjusting means weight valve 9a and controlled for a while with the heating power controller of the rice cooking heat source so that it falls below 128 ° C. to satisfy certain conditions. Even when the heat source is turned off, the rice cooking state continues (the temperature in the pan continues for more than 100 ° C in the atmosphere for the time being, so the rice continues to be alpha). Each rice grain is quickly permeated with water to the core of the rice grain, the surface of the rice grain is glossy, the tongue feels good, the elasticity is good, and the chewing response is good. Can cook.
2. It can be made at a low price because it can be made of materials that can be mass-produced with fewer parts than the pressure rice cookers currently on the market, and less attention to the material of the pan.
3. In terms of safety, there is no anxiety because it is the same method as the pressure-resistant latch structure of a pressure cooker with a history.

4). During cooking, when the high pressure cooker temperature sensor (not shown) provided at the bottom of the high pressure cooker 2 senses 100 ° C., the power of the rice cooking heat source (not shown) is heated so that the temperature continues for a while. If you stop after controlling, you can cook rice that is suitable for grilled rice and curry, and quickly cook it at high pressure and high temperature that can be cooked only from the input information of the heating power controller (not shown) from rice cake rice to rice cracker rice It is a cooked eco-high pressure rice cooker.

Originally, many Japanese people prefer mochi-mochi white rice, but some people like palapara rice for curry rice and baked rice that seasons rice grains, so in the present invention mochi mochi white rice group and health promotion group For cooked rice and curry, the pressure can be controlled at the same time by controlling the temperature with a superheated power controller, and the rice is cooked from high-pressure and high-temperature cooked rice to low-pressure and low-temperature cooked rice. Can be cooked separately.
You can also cook at high pressure and high temperature to soften muscles and fish bones.

When boiling for the purpose of stirring the rice grains during cooking, steam is slightly ejected, but the heat source is controlled or stopped at a stage where there is almost no other, so rice cooking water (because only the water absorbed by rice) is less, and the house The indoor humidity does not increase because it does not emit water vapor indoors.
Even at low altitudes, etc., the internal pressure rises to the specified pressure due to the pressure of water vapor generated by heating regardless of the external pressure, so that rice can be cooked in the same way as low altitudes at normal atmospheric pressure.

  Hereinafter, an eco-high pressure rice cooker according to the present invention will be described with reference to the drawings.

First, FIG. 1 is a front view of an eco-high pressure rice cooker that cooks extreme rice at high pressure and high temperature.
The upper part is the vertically openable open / close rice cooker body lid 1b, the lower part is the rice cooker body case 1a, and the high pressure pan lid handle 3a is in the same position as the high pressure pan handle 2a (heat retaining position). If the rice cooker body lid opening button 12 is pressed, the rice cooker body lid opening mechanism (not shown) is released and the vertically openable rice cooker body lid 1b is opened in the vertical direction.

  Further, when the inside of the high pressure cooker 2 becomes a high pressure and a high temperature, and the pressure rises to an absolute pressure of 2,44 atm. Squirts into the atmosphere and the inside of the high pressure cooker 2 boils, so the rice grains are agitated and at the same time a superheat power controller (not shown) supplies power to the rice cooking heat source (not shown) as the temperature of the high pressure cooker 2 Is controlled for a while so that the temperature below 128 ° C. continues for a while, and then stops.

  Even after the supply power is stopped, the inside of the high pressure cooker 2 continues to be at a high pressure and high temperature (cooking state far exceeding the boiling temperature of 100 ° C in the atmosphere), and the pressure and temperature gradually decrease. When the pressure becomes the same as the atmospheric pressure, the pressurizing display bar 7a is lowered by gravity and the high-pressure pan lid misopening prevention means safety lock 8 is released from the high-pressure pan pressure-resistant latch 4 of the high-pressure pan 2. The inside of the high pressure cooker 2 is in a steamed state, and steaming continues for a while and rice cooking is completed.
