Description
The utility model relates to a kind of household electrical appliance, particularly a kind of electric heating cooker that adds.
Present existing electric cooker partly is made up of pot body, heating, base, magnetic steel temperature limiter, temperature controller, supply socket etc., and what have also adds time timer, is used to control heat time heating time.In use, electric cooker be connected with the mains always, a pot body is placed on the heated base, generally can only be used for cooking, Baoshang, and the thermal efficiency be not high, has only about 70%.
The purpose of this utility model just provides a kind of novel structure, has the efficient automatic electric rice cooker of multiple function.
The utility model mainly is made up of pot body, heating, energy-storage travelling wave tube, magnetic steel temperature limiter, overtemperature prote device, temperature controller, heat-insulation layer, interior cover, shell and supply socket.Heating adopts common nichrome or Aludirome to make electrothermal tube, and energy-storage travelling wave tube is to adopt the big and big lithium nitrate (LiNO of latent heat of phase change of thermal capacitance
3), or NaOH (NaOH), or lithium hydroxide (LiOH), or aluminium and fusing point thereof be that the aluminium alloy of 360～600 ℃ of scopes is made, the aluminium alloy that is adopted is: alusil alloy, wherein silicone content is that 0～17%(all is weight percentage, and is as follows); Almag, wherein the content of magnesium is 0～35%; Aldray, wherein the content of magnesium is 0～15%, the content of silicon is 0～17%; Aluminium magnesium copper alloy, wherein the content of magnesium is 0～15%, the content of copper is 0～17%; The aluminum bronze silicon alloy, wherein the content of copper is 0～17%, the content of silicon is 0～15%.Energy-storage travelling wave tube is made a flat Cylinder, electrothermal tube is cast in the Cylinder (is collectively referred to as the electric heating energy-storage body), with ordinary carbon steel as shell and sealing, liquid that can not outflow during with the not oxidized and phase transformation of protection energy storage material.Limit warm magnet steel to be fixed on energy-storage travelling wave tube central authorities, magnet steel temperature-sensitive face keeps contacting with the bottom of a pan.The center upper portion of cover between energy storage body and interior cover, was filled with the heat-insulation layer that one deck is made with heat-insulating materials such as alumina silicate, calcium silicates, rock wool or perlites in whole electric heating energy-storage body was fixed on.The heat-insulating shield that upper surface at the bottom of electric cooker has a circle to make with safety glass, pottery or enamel material round energy-storage travelling wave tube.Interior cover is on the coat fixed by three fixed legs.Between interior cover bottom and overcoat base, be provided with magnet steel and limit warm interlinked mechanism, the wireless warming dish overtemperature prote device of temperature controller and whole heating board, link with the electrical equipment box that is fixed on the shell.
Operating circuit of the present utility model adopts the electric heating energy-storage body in parallel with indicator lamp, simultaneously by K switch
1Shelves and magnetic steel temperature limiter J
1Be composed in series a branch road; By K switch
2Shelves are formed the second branch road; By K switch
3Shelves and temperature controller J
2Be composed in series the 3rd branch road; By K switch
4Shelves are formed the 4th branch road with the bidirectional triode thyristor circuit, after four branch road parallel connections, connect an overtemperature prote device again in way circuit, have so just realized four kinds of function conversion.
When the utility model is used as automatic electric rice cooker; With K switch
1Shelves are connected, and other switch shelves disconnect, and magnetic steel temperature limiter interlinked mechanism button is pressed, and have only magnetic steel temperature limiter this branch road conducting in the circuit this moment, the heating heating, and mostly branch heat is passed to a pot body, is used for cooking rice, and the remainder heat is stored in the energy-storage travelling wave tube.Fast when cooked (water in the pot is dried) when rice, the magnet steel loss of excitation is under the effect of magnet steel inner spring and outside interlinked mechanism, cut off the electricity supply, stop heating, that part of heat that is stored in the heat accumulation element continues meal is boiled and is incubated, and has so just realized the purpose of automatic electric rice cooker.
When the utility model is used as electric chafing dish, with K switch
2Shelves are connected, and other switch shelves disconnect, and this moment, electric heater directly added heat energy storage element, and effective power can reach more than the 900W, are well suited for the sparking pot.When the required energy in the external world hour; heat energy just is stored in the energy-storage travelling wave tube; because the effect of energy storage and adiabatic heat-insulation; firepower can be more and more violent; when if the temperature of heat accumulation element surpasses certain value, the overtemperature prote device effect in the way circuit disconnects circuit; too high with restriction energy-storage travelling wave tube temperature, protection energy storage body.When the required energy in the external world is big, as when adding more raw and cold food, energy-storage travelling wave tube is with regard to release heat, to satisfy the requirement of the strong firepower of sparking pot.When the sparking pot draws to an end, but power cutoff leans on the store heat of energy-storage travelling wave tube can be maintained to end.
The utility model is during as wireless warming dish, with K switch
3Shelves are connected, and all the other shelves disconnect, and at this moment have only temperature controller J
2This branch road conducting, electric energy is transformed into thermal energy storage in energy-storage travelling wave tube, and energy-storage travelling wave tube also has higher latent heat of phase change except that bigger sensible heat is arranged, can charge into more electric weight.Charge to one regularly, temperature controller J
2The power supply plug wire is pulled up in tripping, can be used for the insulation of soup, dish or beverage, and temperature retention time can reach more than 1 hour.
The utility model is during as electronics watt pot, with K switch
4Shelves are connected the rest switch shelves and are disconnected, and have only K switch this moment
4The branch road conducting of shelves and bidirectional triode thyristor circuit composition is by current-limiting resistance R
1Controlled the angle of flow of bidirectional triode thyristor with the circuits for triggering that capacitor C and diac E form, thereby realized regulating the heating power of heating, mean power is remained on about 200W, be particularly suitable for slow fire and simmer soup or cook congee etc.
The utility model has utilized energy owing to adopted the high phase-changing energy storage material of energy storage density effective and reasonablely, again owing to adopted heat-insulating material efficiently, makes to the utlity model has the higher thermal efficiency simultaneously.When the automatic electric rice cooker, when the thermal efficiency reached 85% or more as electric chafing dish, the thermal efficiency can reach 85～90%, and when being used as electronics watt pot and wireless warming dish, the thermal efficiency can reach more than 75%.On the whole, can save energy () more than 10～30% than ordinary electric rice cooker, electronics watt pot, warming dish, electric chafing dish.The utility model modern design, simple in structure, four kinds of functions can be changed easily, during simultaneously as warming dish, have also saved the trouble of the line that need always plug in use.
