Description

  The present invention relates to a rice cooker with a high pressure resistance horizontal rotating hanging pan structure that cooks rice with high pressure and high temperature while providing a rice cooker lid that opens and closes freely through a hinge for opening and closing the lid.

When I bought a pressure rice cooker while watching TV commercials and expecting it, and chewing rice on a commercially available blended rice, I could only cook rice that had a rough feeling on the tongue, which was disappointing.
So, when I put out an old hakama, repeated the cooked tasting of the above-mentioned general blended rice by reshaping the curled lid by reproducing the furnace and repeating the rice cooking test, the time when I cooked with a heavy stone on the lid was one. It has been found that the rice can be cooked close to the texture of the new rice of Ban Koshihikari (the surface of each grain of rice is glossy, touching the tongue, chewing, elasticity, the sweetness that spreads in the mouth as you chew).
In the conventional pressure rice cooker, the reason why only commercially available blended rice can be cooked in crisp rice is that the pressure and temperature during cooking are low.

  The structure of the conventional pressure rice cooker was composed of a rice cooker case and a lid opening / closing hinge and lid opening catch so that the pan and lid could withstand the internal pressure of the pan. The pressure could not be increased to more than 5 atm (absolute pressure, hereinafter referred to as absolute pressure) because the lid opening / closing hinge and the lid opening catch could not withstand any more pressure.

So, using a conventional cooking pressure cooker, the first time of cooking the general blended rice at a high pressure of 2.41 atm, the second time cooking at a medium pressure of 1.68 atm. The taste was great, but the second medium-pressure cooked rice has a low texture of rice grains, the grain of rice grains are not glossy, the crumbled rice grains have a rough feeling on the tongue, they are chewing It is clear that high-pressure rice cooking is better, such as less sweetness, but it is very inconvenient to open and close the lid of ordinary cooking pressure cookers, steam is filled indoors from the pressure regulating weight valve during cooking, and it is attached for monitoring the heat source It must be cut. In addition, there were drawbacks such as lack of heat insulation equipment.
However, there has been a technique for overcoming the above-described drawbacks (see, for example, Reference 1 and Reference 2), but the above-mentioned literature technique has a major drawback.

1. Since most of the safety devices of the pressure cooker are equipped on the lid, and the lid tightening and releasing functions are provided on the lid, the structure of the lid is complicated and expensive.
2. The device for preventing misopening during pressurization in the pan is very poor.
3. No external display is provided when the pan is pressurized.
4). Since the lid does not have a heat source for heat insulation, high-quality heat insulation cannot be performed.

1. The pressure cooker and its lid are elastically clamped, and when the pressure cooker internal pressure rises, the pressure cooker is displaced downward and the heating power switch contact is turned on and off by that amount of displacement. In this structure, it is possible that the function of the elastic locking part will deteriorate due to secular change, leading to a major accident rather than just a steam leak accident.

The problem to be solved is that the conventional pressure of the commercial rice cooker cannot increase the pressure and temperature during cooking. It becomes.

    In the present invention, as in a conventional pressure rice cooker, not only the packing is put between the pan and the lid, but also the upper periphery of the pressure cooker is folded outward and the pressure cooker lid is folded inward at six locations. The pressure cooker is provided via a pressure cooker lid case 3b hinge (not shown) horizontally provided between the rice cooker case 1a and the pressure cooker lid case 3b at the time of normal heat insulation. The lid case 3b is opened and closed in a vertically rotatable manner to take out the rice. At the time of rice cooking, the high pressure cooker 2 is housed in the pressure cooker case 6 installed in the rice cooker case 1a, and the high pressure cooker lid 3b is mounted and fixed. With the pressure cooker lid case 3b closed, the pan handle 2b is moved to the pan handle rice cooking position 2bb (right side of FIGS. 1, 2 and 3), that is, the high pressure resistant cooker 2 main body is rotated 30 degrees horizontally. Depending on the situation, the pan latch 2a and the lid latch 3a Pressure 2.45 atm as a high-voltage power structure becomes a fixed state, the temperature is achieved safely higher α of rice to every grain of core rice raised to 128 ° C.

  Also, the internal pressure of 2.45 atm of the high pressure cooker 2 is received only by the pan latch 2a and packing 8 of the high pressure cooker 2 and the lid latch 3a of the high pressure cooker lid 3, and the rice cooker case 1a The pressure cooker lid case 3b provided with the pressure cooker lid case 3b has a structure that does not cover the opening / closing hinge (not shown) and the rice cooker lid opening catch 11 at all.

  Even if the pressure in the pan during cooking is 2.45 atm. The cooking temperature is raised to 128 degrees C and the state where a heavy stone is placed on the lid of an old feather pot is cooked, and the heat source is turned off when certain conditions are met. Heating and holding pressure continues (the temperature in the pan continues to boil in the atmosphere for the time being) The rice cooking state (rice α conversion) is advanced and rice can be cooked by heating for a short time, saving energy The core is gelatinized, the surface is glossy, the tongue feels good, the elasticity is good, and the chewing response is good. The more you chew, the more sweet rice will spread in your mouth.

  During cooking, when the pan temperature sensor (not shown) provided at the bottom of the high pressure resistant cooker 2 senses 100 degrees C, the power of the rice cooking and heat-retaining heat source (not shown) is heated so that the temperature continues for a while. ) And then stop, you can cook rice suitable for baked rice and curry, that is, it can be cooked only from the input information of the heating power controller (not shown) from glutinous rice to flaming rice without releasing steam to the outside It is a cooker that can.

Originally, rice varieties include japonica rice and indica rice. The preference is japonica rice white rice type.In the present invention, when you want to eat mochi mochi white rice, cook rice at high pressure and high temperature.When cooking rice or curry, you can control the pressure at the same time by controlling the temperature with superheat power controller. Because you can cook at low temperature, you can also cook rice.
You can also cook with high-pressure and high-temperature stew that softens muscles and fish bones.

  Also, since the heat source is controlled and stopped at a stage where almost no water vapor is generated, the amount of cooked rice water (because only the water absorbed by rice) is small, and the indoor humidity does not rise because water vapor does not diverge into the house.

  Hereinafter, a high pressure-resistant horizontal rotation latching-pot structure rice cooker 1 having a vertically rotatable open / close lid according to the present invention will be described with reference to FIGS. 1 to 11.

  First, FIG. 1 is a right side view of a high-pressure-resistant horizontal rotating latch-type rice cooker 1 having a vertically rotatable open / close lid. The upper is a pressure cooker lid case 3b and the lower is a rice cooker case 1a. 11 is pulled upward, the pressure cooker lid case 3b is located on the upper right side of FIG. 1 via the pressure cooker lid case 3b opening / closing hinge (not shown) and is located on the upper right side from the CC and DD parts. (Vertical), the arrow C-C below is the high pressure-resistant cooker 2 and the rice cooker case 1a, and the arrow D-D is the diagram of the high pressure-resistant cooker lid 3 and the pressure cooker lid case 3b. 4.

Take out the high pressure cooker 2 from here, put a proper amount of cooked rice and water, and put the pan handle 2b of the high pressure cooker 2 in the pressure cooker case 6 at the warming position (left side of FIGS. 1, 2 and 3). Close the pressure cooker lid case 3b until the rice cooker lid opening catch 11 is hooked, and slide the pan handle 2b to the cooking pan position 2bb (the right cooking position in FIGS. 1, 2 and 3) ( When the high pressure resistant cooker 2 is rotated 30 degrees horizontally), the pan hook 2a and the lid hook 3a are hooked and fixed, and the preparation of rice cooking is completed.

  Here, when a current is applied to the rice cooking and heat retaining heat source, the temperature of the high pressure resistant cooker 2 rises and at the same time the pressure rises. When the pressure is pressurized, the pressure cooker lid of the safety lock means arm 10b is accidentally opened. Preventing safety lock means A part of the right side of arm support pin 10bb, pressurizing display pin 10c, and pressure pan lid misopening prevention during pressurization. At the same time as the safety lock means piston 10a is pushed up, the pressure cooker lid inadvertently prevents the safety lock means arm 10b from lowering on the pan hook 2a portion, and the pressure display pin 10c protrudes above the pressure cooker lid case 3b. The high pressure cooker 2 and the high pressure cooker lid 3 are never opened until the internal pressure of the high pressure cooker 2 returns to the same pressure as the atmospheric pressure.

Also, if the internal pressure of the high pressure resistant pan 2 exceeds 2.45 atm, the pressure regulating means weight valve 4a is actuated to escape to the atmosphere. In the present invention, the pressure regulating means weight valve 4a is actuated. Since the power supply to the rice cooking and heat-retaining heat source (not shown) is controlled by a heating power controller (not shown) just before the steaming, there is almost no steam blowout into the atmosphere.
If an abnormality occurs in the heating power controller means or the pressure adjusting means 4 and the internal pressure rises, the safety valve 9 operates to release and reduce the pressure into the atmosphere.

  The inside / outside air communication means arm 5 during the warming operation is such that the pan handle 2b is on the left side of FIG. 1, FIG. 2 and FIG. The inside / outside air communication means arm 5 is pushed up through the adjustment screw 5a and the pressure regulating weight valve 4a is pushed up to communicate the inside / outside air.

  High pressure-resistant cooker 2 and high pressure-resistant cooker lid 3 are made of stainless steel + aluminum + stainless steel clad material, which is advantageous for heat-retaining inside and outside the heat-conducting pan. Rice cooker case 1a, pressure cooker lid case 3b is made of heat-resistant resin, packing 8 is made of silicone rubber, and the adhesiveness improves as the internal pressure increases in the shape shown in the figure.
