Description

Water straining type high pressure rice cooker

Technical field

The utility model relates to electric cooker, pressure cooker field, especially a kind of equipment for utilizing Water straining type steamed rice.

Background technique

Electric cooker has become essential electrical appliance of cooking in family, since cooked rice is mostly all with stronger Sticky property, when using existing electric cooker cooking rice, since moisture is not easy to control, the viscosity of rice itself is larger etc. because Element, therefore the rice mouthfeel that boiling goes out is extremely difficult to preferable level, and rice it is cooling after can be hardened knot tying phenomena such as, It is poor to eat or be used for again mouthfeel when fried rice, and operating difficulties.

What southern region of China tradition used crosses Water straining type boiling rice method, and method is to boil the heating of rice water When medium, rice is filtered from water and is opened, placed into special bulk containers and heated using steam, what this mode boiling went out Rice be avoided that electric cooker boiling go out rice viscosity it is larger, cold meal return it is hard the defects of, but the method because operation sequence it is cumbersome, The energy is larger etc. that factors make it be not easy to largely be promoted for consumption.

Summary of the invention

Above-mentioned to solve the problems, such as, the utility model provides a kind of Water straining type high pressure rice cooker, and the equipment is by close Drainage steamed rice basket, the composition such as controller system and pressure piston lifting device, the bottom of pot body are equipped with inside the pressure cooker body of envelope Plate is equipped with electric hot tray, and the inside of pot body is equipped with high pressure inner body, and the inside of high pressure inner body is equipped with steamed rice basket, and top cover is equipped with pressure Piston lifter, the inside of pressure piston lifting device are equipped with cylinder and piston, and lift lever connects piston and hook, the equipment The water of pot nside and the grain of rice are heated to achieve the purpose that cook by electric hot tray when work, the water to pot nside is heated to Controller closes the exhaust passage inside gas-controlled element at 100 degree, and the water of pot nside continues the height generated after heating at this time Body is calmed the anger by the piston upwards inside pusher cylinder, is lifted up steamed rice basket by the effect of lift lever and hook, this When steamed rice basket will boil to the medium grain of rice and filtered out from water, the high steam and heat for continuing reliance on water body generation are steamed Ripe, controller disconnects the power supply of electric hot tray after the time of setting to be achieved, and the exhaust passage inside gas-controlled element is opened, to Steamed rice can be completed after the pressure decline of pot nside, since the equipment is using the steamed rice mode of traditional Water straining type, so boiling Rice viscosity out is lower, and knot tying will not occur for cold meal, and whole process is by the way of hyperbaric heating, and the time of cooking rice is than passing The time of system electric cooker steamed rice is short, therefore can more save the energy.
