Abstract

The utility model relates to a temperature control double-tube multipurpose electric cooker, which is composed of a cooker body (1), a timer (2), a cooker liner (3), and a cooker cover (4). A timing contact B of the timer is connected to a thermoswitch K (2), a motor M of the timer is connected to a rectifying diode D, A direct connection contact An of the timer is connected to the thermoswitch K (2), the motor M, a sub heating tube R (1), and a main heating tube R (2), and the sub heating tube R (1) is connected in series with the rectifying diode D. The utility model adopts the technology of the temperature control timing and the temperature control transformation power, having the advantages of accurate timing, high control reliability, convenient operation, convenient operation, low cost, and easy popularization.

Description

The two-tube electric cookers of using of Temperature Control Type more

The utility model relates to a kind of family expenses electric cooker that boils, and particularly one has temperature control and regularly boils the two-tube electric cookers of using of the Temperature Control Type of power auto-conversion function more.

In the prior art, popular electric cooker function singleness, be only limited to the control automatically of cooking, and cook congee, boil soup, very important persons such as fricassee guard, use inconvenience, computer-shape electric cooker multiple functional, but complex structure, cost an arm and a leg, it is limited to popularize face, and the inventor proposes patent " the two-tube energy-saving multi-purpose electric cooker " patent No. 922422826, on the basis of popular electric cooker, the electric cookers of using that improvement becomes regularly and transformation into itself's power boils more, for people provide a kind of multifunctional product of high quality and at a reasonable price, but it is to pick up counting when beginning to heat, the Stewed Dish amount how much owing to stewed, seasonal temperature, the influence of factors such as voltage height, it regularly presets restive accurate, the quality that influence is boiled.

The purpose of this utility model provides a kind of improved Temperature Control Type is two-tube uses electric cooker more, has adopted the temperature control timing technology, boiling time in accurately control is stewed, and the direct-reading preparatory function, the adaptation people use needs.

The purpose of this utility model can realize by following measure, this electric cooker is the improvement product based on two-tube energy-saving electric rice pot, its frame for movement can design identical, be made up of pot body, pot courage, pot lid, timer, temperature limiter and warmer, the timing contact that electric meal is protected timer connects thermoswitch, time motor and commutation diode; The straight-through contact of timer connects the other end of thermoswitch, time motor, and be connected with secondary heat-generating pipe, main heat-generating pipe, commutation diode is connected behind the secondary heat-generating pipe more in parallel with time motor, thermoswitch, and the other end of main heat-generating pipe connects temperature limiter, warmer in parallel.Connect straight-through contact, can directly send electricity to give main heat-generating pipe, connect timing contact, send electricity to give main heat-generating pipe through thermoswitch, when thermoswitch disconnects, power supply send main heat-generating pipe shift heating through diode rectification step-down and secondary heat-generating pipe, and there is alternating voltage at the time motor two ends, the motor rotation timing simultaneously.

Concrete structure of the present utility model and embodiment are provided by the following drawings:

Fig. 1 is a structure chart of the present utility model;

Fig. 2 is a circuit structure diagram of the present utility model.

The utility model is described in further detail below with reference to accompanying drawing: with reference to Fig. 1, Fig. 2, electric cooker has pot body [1], timer [2], pot courage [3], pot lid [4] to form, and timer has K switch in [2] ₁With straight-through contact A, timing contact B, commutation diode D and secondary heat-generating pipe R ₁Series connection, timing contact B connects commutation diode D, time motor M and thermoswitch is decided K ₂, the straight-through contact A of timer connects thermoswitch K ₂Time motor M ₁, secondary heat-generating pipe R ₁With main heat-generating pipe R ₂, the secondary heat-generating pipe R of series connection ₁With commutation diode D and thermoswitch K ₂, time motor M parallel connection, timer can adopt electrodynamic type multiconductor timer, convenient connection indicator lamp, the thermoswitch K of arranging ₂Break-off signal can be 97～98 ℃.Main heat-generating pipe R ₂With temperature limiter K in parallel ₃, warmer K ₄Connect.When timer is connected straight-through some A, be the shelves of cooking, electric current directly send main heat-generating pipe R ₂, send out food in heating pot with rated power, after meal is cooked, temperature limiter K ₃Automatically jump and pull, by K ₄The control insulation.When timer is connected timing contact B, be the shelves of cooking congee, electric current is through thermoswitch K ₂, give main heat-generating pipe R ₂, R ₂, food in heating is heated and stewed, time motor M and diode in series D, secondary heat-generating pipe R ₁Thermoswitch K all in parallel ₂, the two ends no-voltage is poor, timer and heat-generating pipe R ₁Do not work, as about 98 ℃ of pot Nei Wenduda, thermoswitch K ₂, automatic disconnection, electric current is through diode D and secondary heat-generating pipe R ₁Flow into main heat-generating pipe R ₂, because two heat-generating pipe series resistances increase and the diode rectification conversion heating power, simultaneously owing to K ₂, disconnecting, there is alternating voltage at time motor winding two ends, and motor entry into service timing is arrived point, K up to preset time ₁Automatically cut off B point, heat-generating pipe R ₁, R ₂, motor M cuts off the power supply simultaneously, boiling finishes.

The utility model is provided with two heat-generating pipes, adopt the automatically synchronous converter technique of temperature control timing and temperature control power, the soup automation is cooked, cooks congee, is boiled in realization, improve the accuracy that regularly boils, the functional reliability height, multiple functional, operation control easily, convenient and practical, integrated cost is low, is to adapt to popularize wide multifunctional electric rice cooker.

Claims

1, a kind of Temperature Control Type is two-tube uses electric cooker more, and pot body [1], timer [2], pot courage [3], pot lid [4], temperature limiter K are arranged ₃, warmer K ₄With main heat-generating pipe R ₂, main heat-generating pipe R ₂With temperature limiter K in parallel ₃, warmer K ₄Connect, it is characterized in that the timing contact B of timer connects thermoswitch K ₂, when electricity device motor M, commutation diode D; The straight-through contact A of timer connects thermoswitch K ₂, time motor M the other end, and with secondary heat-generating pipe R ₁, main heat-generating pipe R ₂Connect, commutation diode D connects behind the secondary heat-generating pipe and thermoswitch K ₂, time motor M parallel connection.
