Description
Technical field
The utility model relates to a kind of intelligent electric heating pot, belongs to domestic electric heating cooker field.
Background technology
Electric food warmer is because its health, characteristics such as convenient, fast receive praises from customers.But in existing electric food warmer, there are time-consuming, a lot of shortcomings such as expense is electric, expense material, caused the loss and the waste of electric energy, increased use cost.Having as frying, fry in shallow oil, explode, boil etc. that existing electric food warmer has is multi-functional; just set the heating (electrothermal tube) of different heating power according to different purposes; during use; select the heater circuit of corresponding power as required; control by a temperature controller, only reach the maximum temperature, automatically power-off protection; be actually the assembly of each single heating circuit, can not realize automatic control.Part can reach the electric food warmer that the duration and degree of heating is regulated, and generally by microcomputerized control, its complex structure costs an arm and a leg, and maintenance is also inconvenient, has limited its application.
Summary of the invention
The purpose of this utility model is to provide a kind of intelligent electric heating pot, and is simple in structure, cheap, easy to use.
Intelligent electric heating pot described in the utility model, comprise a pot body, pot seat, resistance wire heater and circuit control device, press button and relay are set in its circuit control device, relay, press button and temperature detect switch (TDS) (being temp control switch) series connection in load circuit, relay contact and switch in parallel.
The utility model is simple in structure, on the basis of existing functional electric heating pot, increases relay and press button in circuit control device, can carry out repeatedly the access conversion of difference in functionality electrothermal tube easily, realizes different temperatures control requirement.And after temperature reached the requirement of setting, temperature detect switch (TDS) can make circuit disconnect, and prevented overheated dry combustion method, damage the pot body, had realized intelligent control, safe ready.As requested, temperature detect switch (TDS) can be provided with a plurality of temperature control points, directly is connected in main circuit and each corresponding branch circuit.Except function, can realize the heating mode of intelligent electric heating pot with common electric food warmer.
Description of drawings
Fig. 1, the utility model embodiment circuit theory diagrams.
Among the figure: R1-R3, electrothermal tube R4, R5, big resistance resistance K1-K3, K switch 4-1, K4-2, double switch D1, the D2 of double-pole single throw, light emitting diode WK1-WK3, temperature detect switch (TDS) XP1, attaching plug SB1, button switch K M1, relay J 1-J3, relay contact.
The specific embodiment
Below in conjunction with the embodiment accompanying drawing the utility model is further described.
As shown in the figure, intelligent electric heating pot described in the utility model, electrothermal tube R1-R3 is arranged, K switch 1-K3 connects with electrothermal tube R1-R3 respectively, the switch of the preferred tape light of K switch 1-K3, directly indication, easy to use, be serially connected on the attaching plug XP1 with temperature detect switch (TDS) WK3 then, the way switch K4-1 that double-pole single throw is set connects with temperature detect switch (TDS) WK1, in parallel with K switch 1 then, another way switch K4-2 of double-pole single throw connects with normally opened contact J1, in parallel with K switch 3 then, the K switch 4-2 of double-pole single throw, normally-closed contact J2, resistance R 4, light emitting diode D1, resistance R 1 and temperature detect switch (TDS) WK3 series connection between the live wire and zero line of attaching plug XP1, the K switch 4-2 of double-pole single throw, temperature detect switch (TDS) WK2, press button SB1 and relay K M1 series connection are between the live wire and zero line of attaching plug XP1, and press button SB1 two ends are parallel with normally opened contact J3, resistance R 5 is connected with light emitting diode D2, and is in parallel with relay K M1 then.When kettle temperature reached setting value, temperature detect switch (TDS) WK1-WK3 auto switching made the electric food warmer internal temperature control automatically.Light emitting diode D1, D2's is luminous, can directly show the working condition of electric food warmer under different conditions by indicator lamp.The resistance of resistance R 4, R5 is very big, usually greater than 100K Ω, in order to protection light emitting diode D1, D2 work.
Operation principle:
Disconnecting double-pole single throw is to be the common heating state, by the break-make of K switch 1-K3, can control electrothermal tube R1-R3 heating, realizes different gear heating, promptly different heating powers.
Cut-off switch K1-K3, closed double-pole single throw enters intelligent duty.
When not pressing the button switch S B1, electric food warmer is in the heat insulation work state.When kettle temperature is lower than the set temperature value of temperature detect switch (TDS) WK1, temperature detect switch (TDS) WK1 closure, the electrothermal tube R1 heating of working.When kettle temperature reached the set temperature value of temperature detect switch (TDS) WK1, temperature detect switch (TDS) WK1 disconnected, and electrothermal tube R1 stops heating.
When pressing the button switch S B1, relay K M1 gets electric adhesive normally opened contact J1, connects electrothermal tube R3 heat temperature raising, and closed J3 makes temperature detect switch (TDS) WK1 keep energising, and light emitting diode D2 is luminous simultaneously, and burner on light is lighted; Disconnect normally-closed contact J2, electric food warmer is in the electric cooker duty, and light emitting diode D1 is not luminous, and the insulation indicator lamp extinguishes.When kettle temperature was lower than the set temperature value of temperature detect switch (TDS) WK1, WK2, temperature detect switch (TDS) WK1, WK2 were closed, electrothermal tube R1, R3 work, and kettle temperature rises; When temperature reached the set temperature value of temperature detect switch (TDS) WK1, temperature detect switch (TDS) WK1 disconnected, and electrothermal tube R1 stops heating, and electrothermal tube R3 is also continuing heating; When temperature continuation rising reaches the set temperature value of temperature detect switch (TDS) WK2, temperature detect switch (TDS) WK2 disconnects, relay K M1 dead electricity, normally opened contact J1, J3 disconnect, normally-closed contact J2 closure, and light emitting diode D1 is luminous, the insulation indicator lamp is lighted, electrothermal tube R3 stops heating, because resistance R 4 resistances are bigger, electrothermal tube R1 does not work yet.
After kettle temperature descends, when being lower than the set temperature value of temperature detect switch (TDS) WK2, temperature detect switch (TDS) WK2 closure, but do not make relay K M1 can't get electric adhesive owing to press the button switch S B1, so electrothermal tube R3 does not work.When temperature continuation decline, when being lower than the set temperature value of temperature detect switch (TDS) WK1, temperature detect switch (TDS) WK1 closure, electrothermal tube R1 work begins heating, and kettle temperature will remain in the design temperature scope of temperature detect switch (TDS) WK1.
