Abstract
The utility model relates to the improvement of an electric rice pot whose outer part is provided with a heat preserving layer, and a heating device made up of resistance wires or heating elements is installed between the heat preserving layer and the inner wall of a pot body. The middle of a pot lid positioned on the upper part of the pot body is provided with an air valve, and a heat preserving lid is installed above the pot lid; a heating circuit is provided with a stepless voltage regulating silicon controlled and a resistance-capacity phase shifting bridge. The utility model has the advantages of high thermal efficiency, good thermal insulation and convenient and sanitary use.
Description
The utility model relates to a kind of improvement of electric cooker.
Pot for cooking rice is the cooker that often uses during people live.Cooking and during cooking, generally needing about 100 food to be cooked well-done.Because the boiling point of water is 99.8 ℃ under normal pressure, water temperature reaches 100 and has just no longer heated up.1 ℃ of needs one kilocalorie heat of 1 kg of water intensification, 100 ℃ water becomes 100 ℃ steam, needs 398 kilocalorie heats.People are heating up water when cooking in the heating of pot for cooking rice appearance at ordinary times, no matter how many degree are the appearance temperature reach, a coolant-temperature gage still remains on 100 ℃ in the pot of cooking.Remaining a large amount of heat energy all is transformed into steam by the water absorption and has run away in vain.The actual thermal efficiency that utilizes has only 18%～35%.Waste energy.On the other hand because the effect of the after-heat width of cloth, impel Jiao of oil smoke, dish bits, the food of volatilization to stick with paste and emit peculiar smell, pollute room air.
The purpose of this utility model provides a kind ofly can regulate temperature automatically, and heat energy is directly passed to a pot interior food, the Low temp. cooking rice pot that the thermal efficiency is high.
The utility model is by pot cover, the pot body, heater is formed, the outer setting of pot body has heat-insulation layer (1), the heater of being made up of resistance wire or heater element (3) is installed between heat-insulation layer and internal wall pot body (2), be provided with air valve (5) in the middle of being positioned at pot pot cover on body top (4), insulation cover (6) is installed above pot cover, the power supply of heater circuit is connected to controllable silicon (7), (8) of stepless voltage regulation, the secondary diode (10) and the adjustable potentiometer (11) of being connected to of the diminishing coil (9) of triggering and control circuit.
The utlity model has thermal efficiency height, high insulating effect, characteristics such as health easy to use.
Accompanying drawing 1 is the utility model section of structure.
Accompanying drawing 2 is the heater circuit schematic diagram.
Below in conjunction with accompanying drawing the utility model is further described, the utility model pot body is to be made by the sheet iron punching press.The upper limb of pot body is processed with protruding living edge for tightening pot cover usefulness, can bear 0.5 to 1 atmospheric pressure after the staggered engages and seals of pot cover and pot body edge.Pot cover bottom pot body edge is provided with the power line import, and heater is a sheet steel pipe, and nickel filament is installed in it.Outside at the pot body is equipped with heat-insulation layer, to keep kettle temperature unlikely to external diffusion.The top of pot cover is provided with insulation cover, and the circuit of heater is made the stepless voltage regulation switch by two controllable silicons, and circuits for triggering are capacitance-resistance phase shift bridges, by diode D
1, D
2Respectively when positive-negative half-cycle to controllable silicon input control signal, Rg
1, Rg
2Current-limiting resistance for the control utmost point.The utility model is in use, and is identical with the using method of pressure cooker, treat that water in the pot is boiled after, tap changer is transferred to temperature required scope, treat that food boils power switch to be closed after cooking to get final product.
Claims (1)
