Description

Detailed Description of the Invention

The present invention relates to a pressure cooker. In particular, it relates to an electric pressure cooker with a heat insulation cooking mode that can be remotely controlled.

[0002]

[Background and Prior Art] The principle of cooking food by vapor pressure is described in The New Encyclopedia Britannica,
As reported on page 686 of the 15th edition, Volume 9 (1993), French physicist Dennis Papin puts "The Papin Digester", a saucepan with a safety valve and an airtight lid. Known since 1679, the invention. In 1939, a saucepan-type pressure cooker was introduced by National Presto Industries,
A popular way to cook food in one-third of the time while maintaining the vitamin and mineral content of the food while preserving both taste and color (website: http://www.GoP
resto.com-April 2000).

Many cooks have adopted this European invention and used it to cook food in the usual third to tenth of an hour. At the top of the fashion, at least one pressure cooker was found in a well-equipped kitchen. However, with the advent of fast food restaurants, some misunderstandings about microwave cooking and the safety of pressure cookers, the fashion of this useful cookware has largely gone away.

In Europe, Japan and South Korea, researchers have turned to the development of today's safe, quiet, smooth stainless steel cookers that can rely on the cooking of flavorful and nutritious dishes. . For example in Switzerland,
By Barry Brewstein and Kevin Morrissey,
" Express Cooking " (HP Books, 2000
According to the year, p. 1), the average household has three pressure cookers. With the introduction of the electric model, which can be programmed and left alone, pressure cookers are now in a revival period and have spearheaded all the time-saving equipment used to cook food. Chefs ; Specialized kitchen utensils for home chefs from 1979, see late spring 2000, page 57.

Focusing on the various cookers that are connected to electrical outlets for heating, one finds features that provide convenience and control to cookware not found in previous pressure cookers. For example, US Pat. No. 3,90,111
No. 6,058,049 discloses a removable inner container made of metal or ceramic. This inner container has an air layer between the two containers and is fitted inside the main container with a thermostat electric heating element connected to a stationary metal container. The main container is used for high temperature cooking or frying, and the inner container is used for cooking over time or cooking over low heat. This provides a wide range of applications, but does not focus on energy savings or remote control. Similarly, U.S. Pat. No. 4,591,698 discloses a dual quick cooker with an outer casing for cooking and baking with a retractable power plug and an inner pan with a movable opening.

[0006] As another embodiment of the multi-purpose electric cooker,
There is a rice cooker. This includes US Pat. No. 4,315,13
No. 9 is included, and a rice cooker provided with a detachable cooking pot, which is separate from a heating pot provided with a heat insulating material having a time-specified temperature sensor, is disclosed. U.S. Pat. No. 4,421,9
No. 74 uses "remaining heat" to continue cooking when the heater is switched off, thereby preserving the energy to effectively convert beta starch to alpha starch, or "aging" to produce delicious rice. An electric rice cooker with an improved timer is provided which provides a means for ". U.S. Pat. No. 5,727,448 discloses inner and outer pots separated by an insulating vacuum member that prevents heat from escaping during cooking. The energy storage structure is limited to rice cookers.

An insulated cooker is described in US Pat. No. 5,031,5.
No. 19, which claims a cooking container with an insulating lid. Also, US Pat. No. 5,567,458
No. 1 has an insulated outer container. There, the insulation can be vacuum or adiabatic. U.S. Pat. No. 5,643,485 discloses a cookware with a controllable vacuum with adjacent spaces between the inner and outer chambers that activate or deactivate the insulating properties of the pan. is there. Each cooker has an inner container removably housed in an outer chamber. None of these cookers have a pressure cooker as an internal chamber.

Regarding the electric pressure cooker, US Pat. No. 4,587,405 discloses an electric heating element having a control circuit which allows the cooking time to be preset. U.S. Pat. No. 5,839,357 has a device that uses a motor to safely lock both the food container and its lid and monitors the internal pressure from the outside. None of the above electric pressure cookers have a novel saucepan type handle to safely lock the cooker. Even a traditional saucepan-type pressure cooker requires two handles, one for turning the handle clockwise and one for turning the counterclockwise to seal the cooker. Have. The electric pressure cooker is designed with two handles on the pan lid and two handles on the bottom of the pan that are turned in opposite directions with both hands to seal the container. Thus, pressure cookers with pivoting handles, which require only one hand to operate the means to lock and unlock the container, are easier to use, more efficient to operate, and easier to manufacture. Will be cheaper. Further, the present invention enhances the technique of pressure cooking by providing a remote control and energy storage means. Given the continuing rise in prices for all types of fuel, it would be advantageous to ensure that any device uses minimal energy.

[0009] Therefore, as one wants a nutritious food, but does not want to spend time cooking it, as the number of busy and health-conscious consumers increases, healthy low-fat foods can be safely and very safely consumed. There is a need for a pressure cooker that can be created in a short amount of time and with minimal effort, while also conserving energy and operating at the touch of a finger if desired. The present invention provides novel improvements that make electric pressure cookers safer, quieter, more efficient and convenient to use, and more energy saving.

One unexpected, non-trivial result obtained using the present invention is that in two pressure cooking process modes, food is fully cooked while simultaneously conserving energy. The first cooking mode is active heating or steaming, while the second cooking mode allows the cooking process to be completed with residual heat, while the pressure cooker returns to the same state as ambient pressure.

[0025]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Before describing the disclosed embodiments of the present invention in detail, it should be understood that the present invention is not limited in its application to the details of the particular arrangements shown. is there. This is because other embodiments are possible in the present invention. Also, the terms used in this document are for explanation,
It is not limited in any way.

In general, pressure cookers are designed to contain and control the steam generated as the liquid inside the cooker begins to boil. Thus, the pressure cooker is made of a sturdy and durable material such as stainless steel or high-standard aluminum so that it can safely withstand high temperature and high pressure. Also, the pressure cooker is within the design pressure limit,
Operates at temperatures within the heating and cooling capacity range that affect the properties of food. For example, the design pressure limit is usually 1 or 1/2 atmospheric pressure unit above the atmospheric pressure. Atmospheric pressure at sea level, or atmospheric pressure, is 14.3 per square inch (psi).
It's 7 pounds, or about 15 psi. Accordingly, pressure cookers are designed to withstand pressures from 7.5 psi (low pressure) to 15 psi or higher (high pressure). Typically, the design limit is 15 psi above ambient pressure. In operation, this means that the pressure in the sealed cooker is increased to about 15 pounds above normal pressure at sea level, causing the boiling point of water to rise from 100 ° C (212 ° F) to 120 ° C. It means to raise to ℃ (250 ℃). This allows food to be cooked in about one-third of the normal time, while softening the hard fibers and retaining nutrients. The higher the pressure, the higher the cooking temperature that can be achieved and the shorter the cooking time.

Since the electric pressure cooker automatically reaches and maintains the design pressure, it operates almost silently with minimal steam loss. When the design pressure is exceeded, the pressure regulating valve automatically discharges the overpressure. Some electric pressure cookers, including the cooker of the present invention, are programmed to start operating automatically at the desired time. Furthermore, the advantage of the present invention results from the fact that the pressure cooking pot is housed in an insulated pan. In the first cooking mode, the liquid, usually water, but the juice or dashi and the food to be cooked is actively heated for a short but controlled time. When the heating is discontinued, the food is subsequently cooked to completion in the second cooking mode. In the second mode, the latent heat in the first cooking mode completes the cooking process without additional heat.

Examples of foods cooked in this way include pasta, meat, fish, desserts, vegetables, flavorful stews, grains, beans and soups. Because this cooking process is unique and quick, special cookbooks and pot manufacturer's instructions should be carefully followed.

The novel energy-saving pressure cooker disclosed in the present invention is connected to an outlet that supplies heat to the container and powers a modem that can remotely operate the cooker.
