Abstract
The utility model relates to an electric-heating pressure cooker. A traditional electric-heating pressure cooker adopts an exhaust mode for reducing pressure. An exhaust hole is small. When the traditional electric-heating pressure cooker is used for boiling food with great concentration, the exhaust hole is blocked. At the time, if firepower is not reduced, pressure in the cooker rises. An explosion can be easily generated. Meanwhile, energy consumption exists. The electric-heating pressure cooker is characterized in that a fixed-pressure control mechanism is arranged on a cooker body. The firepower is controlled by utilizing the pressure in the cooker. Thereby, the pressure is controlled. Pressure is reduced without using the exhaust mode. Even if the food with great concentration is boiled, the exhaust hole can not be blocked. Therefore, the utility model has the advantages of safe and convenient operation, energy saving and high efficiency.
Description
The utility model relates to a kind of family kitchen mess kit, specifically refers to a kind of electric pressure-cooker.
Existing electric food warmer, the time of steaming, cooking food is long, and energy consumption is big, if can save time with electric pressure-cooker, reduce energy consumption, press the pressure cooker that G813623 produces at present, adopt the exhaust mode decompression, steam vent is little, and the food that the boiling down degree is big stops up steam vent unavoidably, and at this moment if do not reduce firepower, pot inner pressure continues to rise, and easily causes the electric pressure-cooker blast, though fuse sheet can be protected some danger, under fuse sheet poor quality's the situation, it is just unavoidable to explode, in addition, do not reduce firepower, waste electric energy yet.
It is a kind of safe and reliable that the purpose of this utility model is to provide, and energy efficiency is not afraid of the electric pressure-cooker of obstruction.
The purpose of this utility model is to realize like this, device level pressure controlling organization on the pot body of electric pressure-cooker, the level pressure controlling organization is by gravity piston, main, secondary contact-making switch, position-limit mechanism is formed, one end of piston is communicated with in the pot body, and other end device is in the shell of level pressure controlling organization, and secondary contact-making switch is assemblied on the piston support plate, one utmost point of main contact-making switch is contained in the bottom of valve piston, another utmost point is on support, and position-limit mechanism is arranged on the shell, controls the break-make of main contact-making switch, when pot inner pressure increases to certain value, gravity piston rises, and is main, secondary contact-making switch disconnects, no longer heating; When pressure reduced, gravity piston descended, and secondary contact-making switch is connected, and kept the small-power heating.
Because the utility model has installed the level pressure controlling organization on the pot body, the size by pot body internal pressure control electrical heating power can not produce a pot inner high voltage limit; And can be after pressure rise, with the heating of small-power heating element, this electric pressure-cooker is without the steam vent exhaust, and there is not obstruction in the food that the boiling down degree is big yet, and is therefore safe in utilization, efficient energy-saving.
Below in conjunction with accompanying drawing the utility model is elaborated.
