Abstract

An electrothermal boiler with function of stewing rice and holding thermal is belong to household electrothermal cooker field, which includes a heating boiler, a heating cord, a temperature controller which is connected with the heating cord in series, and a heating cord switch equipped on the series connecting circuit. The character of the invention is that: a constant-value temperature controller is parallel connected with the temperature controller and the heating cord switch, and the constant-value temperature controller is equipped with a control switch. Through setting the constant-value temperature controller, temperature can hold below a constant value, moreover, the temperature can switch according to need of user. So that, the invention conquers disadvantage of traditional electrothermal boiler that upper limit control of temperature is higher, and realizes simple structure and convenient maintenance.

Description

Have cook rice over a slow fire, the electric food warmer of heat insulation function

Technical field

Have cook rice over a slow fire, the electric food warmer of heat insulation function, belong to domestic electric heating cooker field.

Background technology

Electric food warmer has in the market had multi-functional, as frying, fry in shallow oil, explode, boil etc., 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, but function is also more single, is incubated, the function of cooking rice over a slow fire is undesirable.The independent electric cooker of general use so cook rice over a slow fire.The user need lay in many cookers, uses inconvenient.Can reach the electric food warmer that the duration and degree of heating is regulated, generally by microcomputerized control, its complex structure, price comparison costliness.

Summary of the invention

Technical problem to be solved in the utility model is to increase to cook rice over a slow fire and heat insulation function on the basis of existing functional electric heating pot.

The technical scheme that its technical problem that solves the utility model adopts is: have cook rice over a slow fire, the electric food warmer of heat insulation function, comprise electric food warmer, 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: be parallel with the definite value temperature controller on temperature controller and heating wire switch, the definite value temperature controller has gauge tap.

The utility model is to increase the definite value temperature controller on the basis of existing functional electric heating pot on its control circuit, and other adjustment can be provided easily.The definite value temperature controller can be in parallel more than one or one, and the definite value temperature of every definite value temperature controller is inequality.The utility model has especially increased cooks rice over a slow fire and heat insulation function, and described definite value temperature controller is two, and the definite value temperature is set at respectively cooks rice over a slow fire 80 ℃-100 ℃, is incubated 50 ℃-70 ℃.

Advantage of the present utility model:

Compared with prior art, the utility model is by being provided with the definite value temperature controller that links to each other with electric food warmer, temperature keeps under certain value, and can be according to user's needs switching temperature, changed the higher drawback of traditional electric heating pot temperature upper limit control, realization is cooked rice over a slow fire and function such as insulation, and compares change on original electric food warmer basis only on the circuit of electric food warmer bottom, has realized advantage simple in structure and easy to maintenance.

Among the figure: R1-R3 heating wire K1-K3 heating wire switch S 1 bigeminy gauge tap ST1 temperature controller ST2, ST3 definite value temperature controller

The specific embodiment

Fig. 1 is an example structure schematic diagram of the present utility model.

As shown in Figure 1, temperature controller ST1 connects live wire 220V, heating wire K switch 1-K3 is cascaded with heating wire R1-R3 respectively, and then be parallel between temperature controller ST1 and the zero line, on temperature controller ST1 and heating wire K switch 1, be parallel with definite value temperature controller ST2, be parallel with definite value temperature controller ST3 on temperature controller ST1 and heating wire K switch 2, definite value temperature controller ST2, definite value temperature controller ST3 connect bigeminy gauge tap S1.

The utility model utilizes pot body, heating wire, temperature controller and the control circuit in original electric food warmer.It is in parallel with temperature controller according to user's needs one or above definite value temperature definite value temperature controller inequality to be 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 course of work is as follows: general electric food warmer uses, and after connecting with the mains, bigeminy gauge tap S1 gets to centre position 2 ends, does not insert definite value temperature controller ST2, ST3.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 was elevated to the ceiling temperature of temperature controller ST1, temperature controller ST1 disconnected.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.

After increasing definite value temperature controller ST2, the ST3 of two different definite value temperature, kettle temperature remains on lower temperature.The temperature of cooking rice over a slow fire is set at 80 ℃-100 ℃, and holding temperature is set at 50 ℃-70 ℃.Bigeminy switch S 1 is brought in the needed function of selection by being closed into 1 end or 3.For example, when electric food warmer will be cooked rice over a slow fire, connect the definite value temperature at 80 ℃-100 ℃ definite value temperature controller.Food in the heating wire heating kettle, 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.
