The technical scheme that realizes the utility model purpose is, a kind of electric cooker that can improve the rice quality, comprise loam cake, interior cooking pan body, base and control circuit, described loam cake comprises cover and inner cap, it is characterized in that, inner cap or cover are provided with air admission hole, in cover and be provided with venthole, be connected with the hot gas system assembly between air admission hole and venthole, described hot gas system assembly is equipped with filter at described air admission hole between cover and inner cap.Filter carries out filtration treatment to the gas that enters vortex flow fan by air admission hole.
Above-mentioned hot gas system assembly comprises air inlet, vortex flow fan, heater and the gas outlet that is connected by pipeline, and described air inlet is positioned at the air inlet position of inner cap or cover, and described gas outlet is positioned at the venthole place of inner cap, directly is communicated with interior pot.
Above-mentioned filter is the filter screen of filtered air, or with the air filter of air filter pulp.
Further, described filter is dismountable structure, the air inlet position of inner cap or cover is provided with the outstanding edge that is positioned at inner cap or cover below, described giving prominence to screws button bit along being provided with, correspondence screws button bit and is provided with button on the filter, filter by button with screw being fixed on the outstanding edge of air admission hole of button bit.Conveniently in use for some time, filter is pulled down cleaning, eliminate dirty.
Above-mentioned filter also can removably be fixed on by the mode of buckle or screw thread or screw fastening the outstanding along upper of air admission hole.
Because heater is to gas-heated, whole process is in the state of dry combustion method substantially, and for product safety, described heater is comprised of heating element and temperature sensor or protector, and perhaps heater directly adopts ptc heater.PTC is the abbreviation of semistor, and ptc heater is used for preventing overheated dry combustion method owing to having self automatic regulating power, is fit to very much this device use.
Above-mentioned ptc heater is arranged to pipeline type, is installed in the side of pipeline between vortex flow fan and the gas outlet.Realize and to the gas-heated in the pipeline.
In order to reach better culinary art effect, the temperature of gas outlet is higher than 98 ℃, can promote the gelatinization that the rice upper surface is good like this, adjusts the content of the water vapour of rice top, guarantees the gold moisture content of rice, promotes that rice is more fragrant.
Also comprise the removable cover that is fixed in inner cap, filter below in the technique scheme.The inlet channel of hot gas system assembly extends to the below of inner cap, and separates with the interior pot of splendid attire rice by removable cover.
The control method of the utility model hot gas system assembly is: heater heats first, after heating a period of time, temperature in the pipeline rises and reaches the temperature of appointment, the master controller that is connected with control circuit is opened vortex flow fan according to the state of temperature in the pipeline, by by the gas that becomes high temperature behind the gas outlet, these gases arrive the top of rice to the cryogenic gas that is entered by air inlet through the heater heating.
The beneficial effects of the utility model are, by filter the gas that enters vortex flow fan by air admission hole is carried out filtration treatment, thereby obtain pure gas so that rice is carried out high-temperature heating, promote the cooking quality of rice, and the harmful effect of avoiding the gas of electric cooker outside that rice is caused.
