CN86207063U - Electric pressure cooker - Google Patents

Abstract

The pressure electric cooker of the utility model is used for rice cooking and food stewing and braising for households and small collectivities. The utility model has the advantages of time saving, safety and sanitation, favorable thermal insulating property, and mainly adopts the combination of a temperature controlling electric cooking range and a pressure cooker, being separately manufactured. Thereby, the pressure electric cooker not only solves the contradiction of needing people in charge in the process of rice cooking but also avoids the overflow of rice water which affects sanitation and the occurrence of electric short troubles. The utility model has the advantages of fast rising in temperature, complete utilizing of heat energy, long time and fragrant and sweet and runny rice. The pressure electric cooker is particularly suitable for being used in plateau regions with low pressure in China, and overcomes the defects of both pressure cookers and electric rice cookers.

Description

Electric pressure cooker

The utility model is a kind ofly to be used for family and Stew food is cooked, steamed to small collectives, energy-and time-economizing, the new cooker of safety and sanitation.

Before the utility model was made, at present normally used was that pressure cooker and electric cooker are more general.But these two kinds of pots all exist weak point simultaneously, and in the whole process of cooking, the ripe back of meal does not have control function automatically, does not leave keeping an eye on of people, the sub-fraction heat-energy losses is arranged, and the meal of making can not carry out the insulation of long period all around as pressure cooker.Though electric cooker has the ripe back of meal outage control function automatically, in the whole process of cooking still from not keeping an eye on of people.Otherwise thin rice gruel overflows, the generation that influences health and bring short trouble for electric part.And owing to do not have temperature pressure function in the electric cooker pot, and meal matter is not good enough.

The said electric pressure of the utility model, it had both solved the contradiction that needs the people to keep an eye in the process of cooking, and had avoided thin rice gruel excessive again, influenced the generation of health and electrical short-circuit fault.And have quick heating, heat energy utilization is abundant, good heat insulating, time are long, the fragrant and sweet soft advantage of meal matter, and be specially adapted to the use in China plateau low pressure area, thereby overcome the shortcoming separately of above-mentioned two kinds of pots.

Technical essential of the present utility model is that it has adopted the combination of the pressure cooker that temperature control electricity meal kitchen range and interior pot (5), pot cover (3), safety stifled (2), easing valve (1), sealing ring (4) that can bearing certain pressure constitute, and separately makes and becomes electric pressure.Because the heating temperature of electric pressure is higher than electric cooker, thereby magnetic steel temperature limiter (10) limit control temperature rises to 120 ° ± 5 ℃ by former 103 ° ± 2 ℃, cuts off the electricity supply automatically when holding temperature rises to 80 ° ± 10 ℃ by former 70 ° ± 10 ℃.For guaranteeing forward and backward being heated evenly reliably of interior pot (5) distortion, electric hot tray (7) is contact-making surface bottom interior pot (5) simultaneously, and the deformation rule of visual its specification size is made the concave or convex sphere shape that is certain radian.For guaranteeing coincideing of interior pot (5) and shell (6) end face, improve interior pot (5) heat-insulating property and prevent that the water clock that caused after sealing ring (4) lost efficacy from entering electric hot tray (7), its shell (6) end face is by the band concavity, is interior or outer crimping beveled formation.

Its process of cooking is such, and at first the rice that the ocean is cleaned adds an amount of water and puts into pot (5), covers pot cover (3) and interior pot (5) screw.The plug (13) that plugs in is then pressed main switch (12), and indicator lamp (11) is bright, at this moment, electric hot tray (7) energising heating, heat constantly passes to interior pot (5), kettle temperature is progressively raise, and when temperature reached more than 100 ℃, moisture content is constantly absorbed consumption by rice to be done.But when kettle temperature pressure met or exceeded authorized pressure, safety stifled (2) or easing valve (1) all can be distinguished automatic deflation, reach the purpose of protection.At this moment temperature is also continuing rising, when reaching 120 ° ± 5 ℃, the magnet steel limit temperature (10) of being close to the bottom of a pan promptly loses magnetism, spring loses magnetism with magnetic steel temperature limiter (10) and falls down, and disconnects main switch (12) contact by connecting rod, and electric pressure promptly cuts off the power supply, indicator lamp (11) goes out, sheet metal temperature controller (9) heating temperature is controlled at insulation in 80 ° ± 10 ℃ scopes, and at this moment heating temperature has substantially exceeded 80 ° ± 10 ℃, and its temperature controller switch contact has disconnected already.After the electric pressure outage, when kettle temperature slowly descends, when dropping to 80 ° ± 10 ℃, temperature controller is connected again, and indicator lamp (11) is bright, electric hot tray (7) heating of switching on once more, temperature rises again, when surpassing holding temperature, and the temperature controller heated bending, disconnect once more, so circulation is till with dump.

Claims (4)

1, a kind of cook electric pressure of usefulness of family and small collectives that is used for is characterized in that:

Separately making of a, temperature control electricity meal kitchen range of this pot usefulness and pressure cooker combines.

B, described temperature control electricity meal kitchen range are by main switch (12) and magnetic steel temperature limiter (10) control heating (8), and sheet metal temperature controller (9) is realized connecting and cutting off the electricity supply, and cooks the effect of insulation automatically.

2,, it is characterized in that control heating (8) transfers heat to the bottom surface of interior pot (5) through the closed power supply of connecting of main switch (12) by the described electric pressure of claim 1.After in case meal is ripe, when limit control temperature reaches 120 ° ± 5 ℃, magnetic steel temperature limiter (10) action, main switch (12) is cut off the electricity supply automatically.When kettle temperature is lower than 80 ° ± 10 ℃, sheet metal temperature controller (9) is connected voluntarily, is in keeping warm mode.
