Description

High efficiency multifunction heat storage electric heating furnace

The utility model relates to a kind of household electrical appliance, particularly a kind of electric heating cooker with heat accumulation.

Chinese patent application numbers 90108359.3 discloses a kind of " efficient electric heat tray ", has maintaining serving tray, electric chafing dish, three kinds of functions of electronics watt Slow-Cooker, but it can not use as electric cooker, and the relatively poor shortcoming of heat-insulation and heat-preservation measure.

The purpose of this utility model just provides a kind ofly has electronics watt Slow-Cooker, electric cooker, electricity fire pot and wireless warming four functions in the heat storage type electric heating stove of one.

The utility model is made up of two halves up and down, and the first half skin is a stay-warm case, is placed with the non cohesive gel aluminum pot of being with pot cover in it; The latter half skin is the body of heater lower casing, be the conical plastic goods, its inner face has metal stamping to become the interior holder cover of peviform, the stone or metal plate for standing a stove on as a precaution against fire box is laid in the centre, the box face becomes to be hemispherical, energy storage electric heating piece is housed in the box, stone or metal plate for standing a stove on as a precaution against fire is to be made of last box and following box, two circular holes and a fixed cylinder are arranged at the bottom of following box, and cylinder connects thermostat, and circular hole is the exit of electrothermal tube, between stone or metal plate for standing a stove on as a precaution against fire box and the interior holder cover, be filled with alumina silicate fibre, the body of heater lower casing is equipped with the electric-controlled box of dial type fourth gear single-point control, and supply socket is equipped with in the bottom on electric-controlled box opposite, the metal bottom capping of band ventilation slot is equipped with in the bottom of body of heater lower casing, stay-warm case can separate with the body of heater lower casing, and convenient dissimilar pot uses, and whole electrothermal furnace is supported by the cylinder pin.

Operating circuit of the present utility model adopts electrothermal tube R _LWith diode D and K switch ₁The series connection again with K switch ₂Be in series after the parallel connection, then with thermostat W ₁, W ₂Series connection forms a branch road, electrothermal tube R _LWith K in parallel ₃And K ₄Be in series, again with thermostat W ₂Series connection forms another branch road, indicator lamp X _B1, X _b2 are attempted by power supply and electrothermal tube R respectively _LTwo ends.

The utility model will have the aluminum pot of various batchings to be placed on the stone or metal plate for standing a stove on as a precaution against fire earlier during as electronics watt Slow-Cooker, and K closes a switch ₁, civil power is through electrothermal tube R _LOnly can pass through diode D, K switch ₁And thermostat W ₂Form the loop, become half by diode D power, through thermostat W ₁The control temperature forms energising--off-position, and during energising, the heating energy storage utilizes energy storage to discharge and heats during outage, and the mean power that makes electrothermal furnace reaches the purpose that slow fire is stewing, stew less than 200W.

When the utility model was used as electric cooker, the method for cooking has three kinds: (1) automatic heat preserving formula was cooked.The aluminum pot that rice, water are housed is placed on the stone or metal plate for standing a stove on as a precaution against fire box, and K closes a switch ₂, civil power is by electrothermal tube R _L, K switch ₁Thermostat W ₁, W ₂This branch road conducting, thermostat W ₁Control is cooked, and can boil about 30 minutes, i.e. outage automatically.(2) heat accumulation is cooked.K closes a switch ₄, switched on thermostat W 14 minutes ₂Automatic disconnection at this moment, is placed on the aluminum pot that rice, water are housed on the stone or metal plate for standing a stove on as a precaution against fire, utilizes heat accumulation that meal is boiled.(3) commonsense method is cooked.With K switch ₃Close, in the aluminum pot that rice, water are housed, during the water boiling, can pull out power supply, by heat accumulation in the stove, that meal is cooked.

When the utility model is used as maintaining serving tray, with K switch ₄Close, civil power is by electrothermal tube R _LCan only be toward K switch ₄Current, pass through thermostat W again ₂Form the loop, through 14 minutes, thermostat W ₂Automatic disconnection plays a protective role, and pulls out power line, and at this moment, the heat that utilizes the energy storage alloy block to discharge is done the insulation of soup dish.

When the utility model was used as electric chafing dish, K closed a switch ₃, have only electrothermal tube R in the circuit this moment _L, K switch ₃With temperature controller W ₂The branch road conducting of forming is heated to 400-600 ℃ electrothermal furnace, when temperature surpasses 600 ℃, thermostat W ₂The meeting automatic disconnection, because the energy storage of electrothermal furnace energy, if pull out power supply, at this moment, under the situation of lid of not boiling, soup stock can keep seething with excitement more than 20 minutes in pot.

The utility model is the metal phase change material of good heat-transfer owing to adopt the energy storage density height, and has taked various heat-insulation and heat-preservation measures, makes its thermal efficiency up to 85-90%, and similar Electricthermal furnace with other is compared, and 10-30% can economize on electricity.The utility model current collection watt Slow-Cooker, electric cooker, electric chafing dish, wireless warming in one, multi-use possesses the frying in shallow oil of electric-heating cooking utensil, boils in a covered pot over a slow fire, stewes, boils, fries, various functions such as steaming.
