Description

A kind of control circuit of functional electric heating pot

Technical field

The utility model belongs to domestic electric heating cooker field, is specifically related to a kind of control circuit of functional electric heating pot.

Background technology

Electric food warmer is used by increasing family because of its hygienic and convenient and practical characteristics.The functions such as electric food warmer in the market generally has stir-fry, fries in shallow oil, explodes, steaming, ubiquitous shortcoming is that pot meal effect is undesirable, because pot meal does not need extra high temperature, and needs little fire to simmer.The circuit structure of common electric food warmer is to control a plurality of heating wire by a temperature detect switch (TDS), because its ceiling temperature is higher, so be not suitable for pot meal.Increased the electric cooker temp control switch in the prior art, when the electric food warmer temperature was higher than design temperature, the automatic cutout of electric cooker temp control switch realized pot meal function.As shown in Figure 2, temp control switch ST3 connects attaching plug XP2, K switch 4, K5, K6 connect with heating wire R4, R5, R6 respectively, K switch 4 and heating wire R4, K switch 5 and heating wire R5, K switch 6 forms three shunt load circuit with heating wire R6, be serially connected between temp control switch ST1 and the zero line, rice cooker switch K7 connects with electric cooker temp control switch ST4 and is attempted by K switch 5 two ends, the selection of control pot meal program, this kind control circuit has solved can not the stew problem of meal of common electric food warmer, but structure relative redundancy, circuit connecting mode is succinct not.

The utility model content

The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of circuit connecting mode more simple functional electric heating pot control circuit.

The technical scheme that its technical matters that solves the utility model adopts is: this functional electric heating pot control circuit comprises temp control switch ST1, electric cooker temp control switch ST2, second switch K2 and the second heating wire R2, it is characterized in that: electric cooker temp control switch ST2 is connected between second switch K2 and the second heating wire R2.

Compared with prior art, the beneficial effects of the utility model are: the mode of connecting with second switch K2 and the second heating wire R2 by electric cooker temp control switch ST2, not only overcome the higher problem of traditional electric heating pot temperature upper limit control, realized pot meal function, and circuit is simpler, operates easier.Electric cooker temp control switch ST2 is connected between second switch K2 and the second heating wire R2, when only opening second switch K2, the second heating wire R2 work, when temperature rises to design temperature, electric cooker temp control switch ST2 auto-breaking, the second heating wire R2 quits work, and temperature is when being reduced to uniform temperature, and electric cooker temp control switch ST2 is closed, and the second heating wire R2 resumes work, begin heating, realize the effect of pot meal insulation.

Embodiment

Below in conjunction with accompanying drawing embodiment, the utility model is described further:

As shown in Figure 1, temp control switch ST1 connects attaching plug XP1, the first K switch 1, second switch K2, the 3rd K switch 3 are connected with the first heating wire R1, electric cooker temp control switch ST2 and the second heating wire R2, the 3rd heating wire R3 respectively, the first K switch 1 and the first heating wire R1, second switch K2 and electric cooker temp control switch ST2 and the second heating wire R2, the 3rd K switch 3 and the 3rd heating wire R3 form three shunt load circuit, are serially connected between temp control switch ST1 and the zero line.

Temp control switch ST1 is connected in the circuit at attaching plug XP1 place, can guarantee when the pot soma burns, and realizes auto-breaking, protection pot body.

Electric cooker temp control switch ST2 is connected between second switch K2 and the second heating wire R2, by the direct control of the second switch K2 meal of whether stewing, operates easier.

The utility model principle of work and the course of work are as follows:

As shown in Figure 1, when needing pot meal, open second switch K2, only have the second heating wire R2 to be in heated condition this moment, the power of the second heating wire R2 is little, can realize the miniwatt laser heating, when temperature rises to design temperature, electric cooker temp control switch ST2 disconnects, the electric food warmer stopped heating.Along with temperature of boiler reduces, when dropping to design temperature, electric cooker temp control switch ST2 is closed, and electric food warmer restarts heating, reaches the purpose of pot meal insulation.

In the time of need to stewing other operations beyond the meal, power is as required opened suitable switch, operates.

Claims (1)

1. the control circuit of a functional electric heating pot, comprise temp control switch (ST1), electric cooker temp control switch (ST2), second switch (K2) and the second heating wire (R2), it is characterized in that: electric cooker temp control switch (ST2) is connected between second switch (K2) and the second heating wire (R2).
