Abstract
A multi-function automatic energy saving electric rice cooker, consists of electric heating coil and control circuit, the electric heating coil has one high power thermotube EH2 and one lower power thermotube EH3; the thermotube EH2 is connected in series with the magnetic steel temperature limiting switch ST1 and sudden-trip type temperature controller ST2, and connected in parallel with the indicator HL2 and indicator HL3 to form a circuit; the thermotube EH3 is connected in series with the magnetic steel temperature limiting switch ST1 to form another circuit; the thermal insulating plate EH1 and indicator HL1 are connected in parallel with the magnetic steel temperature limiting switch ST1. This multi-function automatic energy saving electric rice cooker may utilize the sudden-trip type temperature controller ST2 as the power conversion switch, the high power electric rice cooker electric heating coil may give the stored heat and high thermal insulating performance of electric rice cooker, when the liquid begins to boil, switched to the lower power thermotube for maintaining the working temperature of electric rice cooker, thus realize the energy saving purpose. Due to the removal of electronic elements and function switch, reduce the wearing degree of elements and ensure the high quality and stability of the electric rice cooker.
Description
Technical field
The utility model relates to the household electrical appliance technology, particularly a kind of multi-functional automatic energy saving electric cooker.
Background technology
At present, traditional multifunctional and energy-saving electric cooker is to adopt a function switch to switch with the power of manually controlling electric hot tray, the electric cooker traditional method of this form is heavy-duty diode of series connection on the electrothermal tube of electric hot tray, utilize hand to stir functional switch and reach being connected and disconnection of electrothermal tube and heavy-duty diode, thereby reach the purpose that power reduces by half.But the electronic component ratio is easier to damage, thereby has influenced the quality stability of electric cooker.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that above-mentioned prior art exists, to provide a kind of discarding to use electronic component and functional switch, need not the people be the multi-functional automatic energy saving electric cooker of stirring the safe and reliable automatic transfer power of functional switch.
For achieving the above object, the technical scheme that the utility model is taked is: this multi-functional automatic energy saving electric cooker comprises electric hot tray and control circuit, and described electric hot tray is provided with an electrothermal tube EH2 and a small power electric heat pipe EH3 that power is bigger; Electrothermal tube EH2 connects with magnet steel temperature limit switch ST1 and Kick type thermostat ST2, and composes in parallel a current supply circuit with indicator lamp HL2 and indicator lamp HL3; Electrothermal tube EH3 and magnet steel temperature limit switch ST1 are composed in series another current supply circuit; Warming plate EH1 and insulation indicator lamp HL1 are in parallel with magnet steel temperature limit switch ST1.
Described Kick type thermostat ST2 is installed in the inner cap of electric cooker top cover.
The operating temperature of described Kick type thermostat ST2 be 90 ℃ ± 2 ℃, 220V～, 5A～10A.
Described electrothermal tube EH2 is 70% of an electric cooker general power, and electrothermal tube EH3 is 30% of an electric cooker general power.
The multi-functional automatic energy saving electric cooker of the utility model, utilize Kick type thermostat ST2 as power change switch, the heat of the storage that produces and the good thermal insulation property of Xisi, famous beauty in the late Spring and Autumn Period's electric cooker when utilizing the original high power work of electric cooker electric hot tray, when liquid just comes to life, be converted to the small power electric heat pipe and keep the operating temperature of electric cooker, thereby reach purpose of energy saving.Owing to removed electronic component and functional switch, reduced the vulnerability degree of element, make the more stable quality of electric cooker.
Description of drawings
Fig. 1 is the utility model control circuit figure.
The specific embodiment
As shown in Figure 1, be provided with two electrothermal tube EH2 and EH3 in the electric cooker electric hot tray, electrothermal tube EH2 is the bigger electrothermal tube of power, and it accounts for 70% of electric cooker general power, and electrothermal tube EH3 is the small power electric heat pipe, and it accounts for 30% of electric cooker general power.Electrothermal tube EH2 connects with magnet steel temperature limit switch ST1 and Kick type thermostat ST2, and with cook, congee, soup indicator lamp HL2 and energy-saving indicating lamp HL3 compose in parallel a current supply circuit.Electrothermal tube EH3 and magnet steel temperature limit switch ST1 are composed in series another current supply circuit.Warming plate EH1 and insulation indicator lamp HL1 are in parallel with magnet steel temperature limit switch ST1.Described Kick type thermostat ST2 is installed in the inner cap of electric cooker top cover, its operating voltage be 220V～, 5A～10A, operating temperature is 90 ℃ ± 2 ℃.
When magnet steel temperature limit switch ST1 is closed, electric cooker is connected 220V～power supply, electric current is through magnet steel temperature limit switch ST1 → Kick type thermostat ST2 → electrothermal tube EH2 and cook, congee, soup indicator lamp HL2 forms the loop, indicator lamp HL2 is bright, another road electric current forms the loop through magnet steel temperature limit switch ST1 → electrothermal tube EH3, this moment, electric cooker was in normal operating conditions, carried out full power operation.
When electric cooker caping inner cap reached 90 ℃ ± 2 ℃, electric cooker inner container had reached 100 ℃ of boiling points, and Kick type thermostat ST2 moves disconnection, electric hot tray high-power
Electrothermal tube EH2 power supply is cut off and quits work.At this moment electric cooker utilizes the work of the insulating power of stored heat of electric hot tray and electric cooker self and the small power electric heat pipe EH3 in the electric hot tray to continue to keep electric cooker work, and this moment, energy-saving indicating lamp HL3 was bright, and electric cooker enters power save mode.
When the temperature of electric hot tray continues to rise to when making that pot temperature reaches 103 ℃ ± 2 ℃ in the electric cooker, magnet steel temperature limit switch ST1 jumps disconnection, and the power supply of electrothermal tube EH3 is cut off, and it is bright that be incubated indicator lamp this moment, and electric cooker enters keeping warm mode.
When cook congee or the Baoshang process in because the boiling point of water is 100 ℃, electric cooker inner container does not reach 103 ℃, magnet steel temperature limit switch ST1 can not automatic disconnection, needs staff stir and disconnects magnet steel temperature limit switch button, makes electric cooker enter keeping warm mode.
How two electrothermal tube three lamps of the utility model are applicable to 500W, 700W, the luxurious Xisi, famous beauty in the late Spring and Autumn Period's electric cooker of 900W with the automatic energy saving electric cooker.
