Abstract

The utility model relates to a multifunctional electric food warmer body which comprises an electric food warmer body, an electric heating wire, and a temperature controller; wherein, the temperature controller is connected with the electric heating wire in series, and the series circuit is provided with an electric heating wire switch, which is characterized in that: the temperature controller and the electric heating wire switch are connected with two to six rated value temperature controllers of various rated temperature values in parallel, and each rated value temperature controller is connected with a control switch. By providing a plurality of rated value temperature controllers that are connected with the electric heating wire of the electric food warmer, the temperature can be kept under a rated value needed by the users and can also be switched according to the need, thus the utility model alters the defect of difficult upper limit control for the temperature of the common traditional electric food warmer and realized the functions of rice stewing, heat preservation, barbecuing and flapjack baking.

Description

Functional electric heating pot

Technical field

The utility model relates to a kind of improved functional electric heating pot, belongs to domestic electric heating cooker field.

Background technology

Electric food warmer has in the market had as frying, fry in shallow oil, explode, boil etc. multi-functional, set the power of heating (heating wire) according to different purposes, but heating is to be controlled by a temperature controller, reach ceiling temperature, just outage automatically, its function is also more single, cooks rice over a slow fire, is incubated, barbecue, pancake function be undesirable.So cook rice over a slow fire, be incubated, when barbecue or pancake, generally use independent cooker, the user need lay in many cookers, uses inconveniently, it is big to take up space.Regulate electric food warmer freely and can reach the above duration and degree of heating, generally by microcomputerized control, its complex structure, price comparison costliness.

Summary of the invention

The purpose of this utility model is to provide functional electric heating pot a kind of simple in structure, cheap, easy to use, have cook rice over a slow fire, be incubated, barbecue and pancake function.

Functional electric heating pot described in the utility model, comprise Electric heating cooker, heating wire, temperature controller, temperature controller is connected with heating wire, the heating wire switch is set on series circuit, it is characterized in that 2-6 in parallel definite value temperature controller with different definite value temperature on temperature controller and heating wire switch, each definite value temperature controller connects gauge tap.

On the basis of existing functional electric heating pot, on its control circuit, increase the definite value temperature controller, can carry out adjustment easily.The definite value temperature controller has the commercially available prod, directly buys to get final product.The definite value temperature controller can be selected a plurality of parallel connections as required, and general 2-6, the definite value temperature of each definite value temperature controller is inequality, satisfies the different heat requests that adds.The utility model especially increased cook rice over a slow fire, be incubated, barbecue and pancake function, described definite value temperature controller is four, the definite value temperature is set at respectively: the temperature of cooking rice over a slow fire is controlled at 85 ℃-90 ℃, holding temperature is controlled at 40 ℃-60 ℃, the barbecue temperature is controlled at 90 ℃-100 ℃, and the pancake temperature is controlled at 150 ℃-170 ℃.

The utility model is by being provided with a plurality of definite value temperature controllers that link to each other with the electric food warmer heating wire, temperature can keep under the required certain value of user, and can switch as required, changed the difficult drawback of traditional common electric heating pot temperature upper limit control, realized cooking rice over a slow fire, be incubated, barbecue and pancake function.With compare on original electric food warmer, only change on the control circuit of electric food warmer bottom, change easily, realized advantage simple in structure and easy to maintenance.

Description of drawings

The circuit theory diagrams of Fig. 1, the utility model one embodiment.

Among the figure: R1-R3, heating wire K1-K3, heating wire switch S 1, S2, bigeminy gauge tap ST1, temperature controller ST2-ST5, definite value temperature controller.

The specific embodiment

Below in conjunction with embodiment the utility model is further described.

As shown in the figure, temperature controller ST1 connects live wire 220V, and heating wire K switch 1-K3 is cascaded with heating wire R1-R3 respectively, and then is parallel between temperature controller ST1 and the zero line.Definite value temperature controller ST2 and definite value temperature controller ST3 also are connected on the bigeminy gauge tap S1, are connected in parallel on temperature controller ST1 and the heating wire K switch 1 with bigeminy gauge tap S1 then.On temperature controller ST1 and heating wire K switch 1, be parallel with definite value temperature controller ST4, be parallel with definite value temperature controller ST5 on temperature controller ST1 and heating wire K switch 2, definite value temperature controller ST4 is connected bigeminy gauge tap S2 with definite value temperature controller ST5.

The utility model utilizes pot body, heating wire, temperature controller and the control circuit in original electric food warmer, according to user's needs, it is in parallel with temperature controller that a plurality of definite value temperature definite value temperature controller inequality is set, the definite value temperature controller is fixed on the bottom of electric food warmer by conducting strip, when kettle temperature reaches design temperature, definite value temperature controller deenergization, electric food warmer stop heating.

The electric food warmer control circuit except above connected mode, can also adopt definite value temperature controller ST2-ST5 in parallel with temperature controller ST1 and heating wire K switch 1 respectively.

The course of work:

When general electric food warmer used, after connecting with the mains, bigeminy gauge tap S1, S2 got to the centre position, do not insert definite value temperature controller ST2-ST5.Closing Switch K1-K3, heating wire R1-R3 energising makes the electric heating kettle temperature raise.Because original temperature controller ST1 is connected between live wire 220V and the K switch 1-K3, when kettle temperature is elevated to the ceiling temperature of temperature controller ST1, temperature controller ST1 disconnecting circuit, kettle temperature reduces gradually.The ceiling temperature of temperature controller ST1 is generally at 300 ℃-400 ℃, and under this temperature kept, water evaporates was fast in the pot, stuck with paste at the end easily when cooking rice over a slow fire, and also was not suitable for insulation, barbecue and pancake.

After increasing the definite value temperature controller ST2-ST5 of four different definite value temperature, kettle temperature can remain on certain lower temperature.Definite value temperature controller ST2-ST5 can be set at 85 ℃-90 ℃ of the temperature of cooking rice over a slow fire, 40 ℃-60 ℃ of holding temperatures, 90 ℃-100 ℃ of barbecue temperature, pancake ℃ 150 ℃-170 ℃.Bigeminy switch S 1, S2 bring in the needed function of selection by being closed into 1 end or 3.For example, when needing pancake, a needs connection definite value temperature gets final product at 150 ℃-170 ℃ definite value temperature controller; When temperature surpassed the definite value temperature, disconnecting circuit stopped heating.When kettle temperature is reduced to the definite value temperature when following, the definite value temperature controller is connected, and continues heating.

Claims

1, a kind of functional electric heating pot, comprise Electric heating cooker, heating wire, temperature controller, temperature controller is connected with heating wire, the heating wire switch is set on series circuit, it is characterized in that 2-6 in parallel definite value temperature controller with different definite value temperature on temperature controller and heating wire switch, each definite value temperature controller connects gauge tap.
