The utility model is matched with two 'heat selection and 'series connection', 'parallel connection' transfer switches' formed by combination of two three-gear single pole double throw switches K1, K2 of the 'parallel connection', 'turnoff', and the 'series connection'; two independent heat sources are adopted, and operation modes of the 'parallel connection' and the 'series connection' can provide four gears of heat selection of different power. The internal part of a circuit is connected with a boiling circuit breaker; when food carried by an internal port is heated to the boiling point, a portion of circuit can be automatically cut off, and through adopting a manual or automatic mode, users can conveniently save power consumption.
Description
The utility model is to the modified of original electric metal plate pot, electric frying pan and other electric-heating cooking utensil, makes it using electricity wisely in use.
At present, known electric cooking appliance in use, though food what, overall process adopts with the power heating, could cut off the power supply, be incubated after food is ripe.In normal gastronomical process, when being heated to, the food of containing in the pot needs one very long constant temperature cooking time after water boils, and this period is the several times before water boils sometimes, and required heat of this period only is the 20%-60% of full power.Steam many slightly, stewing placed in the middle, stewed minimum.If adopt immutable power heating all the time, must cause a large amount of losses of energy dissipation and food nutrient.
The purpose of this utility model is exactly to keep under the constant prerequisite of original electric cooking appliance basic function, adopting new frame mode, allowing the user according to different needs, selecting heating load, using electricity wisely flexibly.
The purpose of this utility model is to realize like this; Two thermal source electric hot traies that the electrothermal tube that it is 4:6 that single thermal source electric hot tray that an electrothermal tube of original electric cooking appliance is cast changes by two power is cast; On panel, increase by one group of " the heat selection reaches ' string ', ' also ' change-over switch " that combines by two single-pole double-throw switch (SPDT) K1, K2 with " also ", " passs ", " string " third gear, " live wire ", " zero line " (being A, the B point in the accompanying drawing) with original electric cooking appliance controlling organization output, be connected in " also " end of K1, K2 respectively, K1, K2 " string " end is integral with lead, one end of two thermals source connects K1, K2 " also " end respectively, and the other end connects K1, K2 " pass " end respectively.A boiling point circuit breaker (temperature controller of available electric water boiler replaces) is installed on the housing heat-insulation layer at 1/5 place under the pot outside in electric cooking appliance, allow its temperature-sensitive face be close to pot in the electric cooking appliance, two lead-out wires of boiling point circuit breaker are parallel to " string ", " also " end of K1.In use as long as operation K1, K2 can realize manually or automatic energy saving.In the small power electric cooker, then adopt another kind of scheme: with a commutation diode, a boiling point circuit breaker (installation site and last same), the circuit that short switch composes in parallel is connected in series to an end of single thermal source electric hot tray, and the break-make of operation short switch can realize full-automatic energy-saving.
Owing to adopted such scheme, use the utility model can allow the user according to the different requirements of food what and gastronomical process, select heating load flexibly, using electricity wisely.This system all adopts frame for movement, and is simple in structure, with low cost, safe and reliable." heat is selected and ' string ', ' also ' change-over switch " and connecting mode thereof can also be widely used in light modulation, the accent heat of electrical equipment such as lamp decoration (only limiting to incandescent lamp), electric furnace simultaneously.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 manually transfers hot type energy-saving electric rice pot electrical schematic diagram.
Fig. 2 automatically transfers hot type electric cooker electrical schematic diagram, and it is on the basis of Fig. 1, " string " of K switch 1, " also " end in parallel a boiling point circuit breaker constitute.
Fig. 3 adopts commutation diode to do to transfer the small-power of thermal element to transfer hot type fully automatic rice cooker electrical schematic diagram.
Fig. 4 transfers hot type electric frying pan and other to transfer hot type electric cooking appliance electrical schematic diagram.
1,2 thermals source among the figure; K1, K2 heat are selected and " string ", " also " change-over switch;
3, electric hot tray; 4, boiling point circuit breaker;
5, commutation diode; 6, magnetic steel temperature limiter;
7, bimetallic warmer; 8, insulation indicator lamp;
