Fig. 2 is a profile schematic diagram of the present utility model.
Among the figure: temperature fuse 1, magnet steel press button 2, first current-limiting resistance 3, second current-limiting resistance 4, bimetallic automatic temperature control switch 5, electric hot plate 6, insulation indicator lamp 7, burner on light 8, selector switch 9, first temperature detect switch (TDS) 10, second temperature detect switch (TDS) 11, the 3rd temperature detect switch (TDS) 12, the 4th temperature detect switch (TDS) 13, the 5th temperature detect switch (TDS) 14, the 6th temperature detect switch (TDS) 15.Timer 16, electric cooker pot body 17.
The specific embodiment
Fig. 1-2 has shown a kind of temperature controlled multifunctional electric rice cooker of multistage that has, comprise temperature fuse 1, magnet steel press button 2, the first current-limiting resistances 3, the second current-limiting resistances 4, bimetallic automatic temperature control switch 5, electric hot plate 6, insulation indicator lamp 7 and burner on light 8, wherein after burner on light 8 and 3 series connection of first current-limiting resistance again with electric hot plate 6 formation parallel circuits in parallel, parallel circuit is connected with magnet steel press button 2 again, forms heater circuit; After being incubated indicator lamp 7 and second current-limiting resistance 4 being connected, in parallel with bimetallic automatic temperature control switch 5 again, electric hot plate 6 series connection again after the parallel connection, form thermal circuit, described temperature fuse 1 is arranged on the main circuit, connect with heater circuit and thermal circuit respectively, wherein: between the magnet steel press button 2 of described heater circuit and electric hot plate 6 circuits, also be in series with a temperature control and select circuit, described temperature control is selected circuit to comprise and is installed in selector switch 9 on pot body, first temperature detect switch (TDS) 10, second temperature detect switch (TDS) 11, the 3rd temperature detect switch (TDS) 12, the 4th temperature detect switch (TDS) 13, the 5th temperature detect switch (TDS) 14 and the 6th temperature detect switch (TDS) 15, selector switch 1 is rotary selector switch, temperature detect switch (TDS) 10-15 adopts the temperature relay switch of KSD-301 series 250V-10A, the end of described temperature detect switch (TDS) 10-15 connects electric hot plate jointly, and the other end connects the contact of selector switch respectively, when 2 conductings of magnet steel press button, selector switch 9 can only with one of them temperature detect switch (TDS) conducting, it is logical to form heater circuit.Magnet steel press button 2 fronts also are in series with a timer 16, can set heat time heating time as required.
The operation principle of this circuit is as follows: when pressing lower magnetic steel press button 2, selector switch 9 turn-on powers are when selecting the switch 9 and first to the 6th temperature detect switch (TDS) 10,11,12,13,14, when any in 15 connected, electric current makes electric hot plate 6 heating powers by this temperature detect switch (TDS), when temperature rises to the break-off signal of this temperature detect switch (TDS) setting, temperature detect switch (TDS) disconnects, and electric hot plate 6 stops heating; When temperature drops to the reset temperature of this temperature detect switch (TDS), the temperature detect switch (TDS) closure, electric hot plate 6 begins heating again.When the temperature of so continuous circulation food bottom in pot was higher than the operating temperature of magnet steel press button 2, magnet steel press button 2 disconnected, and electric cooker enters the automatic heat preserving state, by 5 controls of bimetallic automatic temperature control switch.So no matter to boil any food, can not boil burnt situation, thereby guarantee to boil the safe and reliable of forget-me-not.
When pot congee, soup, deep fried foodstuff, forwarding selector switch to 1 gear puts, by first temperature detect switch (TDS), 10 control heating processes, the setting of first temperature detect switch (TDS), 10 break-off signals is that the temperature of food in pot is remained between 85 ℃-98 ℃, be below the operating temperature of magnet steel press button 2, no matter boil the time how long like this, magnet steel press button 2 can not disconnect, unless the poach in pot is done.And in heating process, the water in pot can not seethe with excitement continuously and (be little boiling 2-4 minute, stop boiling, 10-25 minute circulation again., hot steam's emission is few, has significantly reduced the loss of moisture content, so continuous pot 4-10 hour, and the water in pot can not stewed dried basically.
The 6th grade of high temperature shelves are by 15 controls of the 6th temperature detect switch (TDS), this temperature can make the water in pot continuously seethe with excitement, thereby reach the purpose of flash-cook, the temperature of pot end electric hot plate 6 is controlled between 140 ℃-165 ℃, when surpassing 165 ℃, 15 automatic disconnections of the 6th temperature detect switch (TDS), electric hot plate 6 stops heating, make its temperature be lower than 170 ℃ of the fusing-off temperatures of temperature fuse 1 all the time, thereby having guaranteed that electric cooker is can Yin Wendu not too high make temperature fuse 1 fusing and can't use.
Second to the 5th temperature detect switch (TDS) 11; 12; it is that segmentation is determined in the operating temperature interval of first temperature detect switch (TDS) 10 and the 6th temperature detect switch (TDS) 15 that 13,14 operating temperature is set, the selection of temperature and the control of digestion time when greatly facilitating the cooking; can cook various foods well; thereby the time of significantly reduced manual intervention, looking after,, and reduced a large amount of hot steams' discharging for people have saved a large amount of cooking the time; save water and electricity consumption, helped environmental protection and health.
First to the 6th temperature detect switch (TDS) 10,11,12,13; the temperature relay switch of 14, the 15 KSD-301 series 250V-10A that adopted, it utilizes the distortion of bimetal leaf heated bending; promote rapid adhesive in contact or disconnection, reach and be switched on or switched off power supply, the purpose of holding circuit or control miscellaneous equipment.Have action accurately, reliable, the low good airproof performance of fault rate, safe in utilization, advantage such as the life-span is long, price is low, use extensively.
