Description

Energy-saving electric pot

The utility model belongs to the mankind life article field, is a kind of energy-conservation electric cooker.

Existing ordinary electric rice cooker has two kinds of user modes: the one, and under the power of setting, heat and cook; The 2nd, under the temperature of setting, be incubated.When electric cooker in process is cooked in heating, because its power is invariable, can not coincide with the power of the process actual needs of cooking, need high-power when not seething with excitement as water, water boiling back only needs small-power, thereby in use will produce a series of problems: at first be to waste electric energy; Next is that excessive thin rice gruel pollutes a pot body case, the kitchen range top when cooking, and easily causes short circuit, is absolutely unsafe; Be that the meal that cooks is second-rate once more, promptly the meal of upper part is rarer softer, and following meal partly is harder again; Pollute the kitchen but also will produce a large amount of water vapours.At present, these problems have become problem anxious to be solved in the electric cooker use.

Task of the present utility model is to solve the problem that prior art exists, and for the public provides a kind of both saves energy, can improve the quality of meal again, reduces and pollutes safer energy-saving electric cooker.

Task of the present utility model is finished by following technical solution:

The present technique solution is on the ordinary electric rice cooker basis that basic parts such as the existing heat induction switch that has interior pot, shell, pot cover, attaching plug, electric hot tray, magnet steel heat induction switch and link to each other with electric hot tray constitute, and also is equipped with a heat induction switch between inner pot outer wall and outer casing inner wall.This heat induction switch can keep excellent contact with inner pot outer wall, be closure state below 97 ± 3 ℃, be off-state more than 97 ± 3 ℃, and in parallel with the commutation diode of installing in the enclosure, and then be connected between magnet steel heat induction switch and the heating wire.

During use, plug in, press the lower magnetic steel heat induction switch after, entire circuit is closure state, electric cooker is just started working with total power.When the temperature of electric hot tray reached 60～80 ℃, the heat induction switch that links to each other with electric hot tray disconnected.When water temperature in the electric cooker reached 97 ± 3 ℃, the heat induction switch that is close on the inner pot outer wall also disconnected.At this moment the circuit of electric cooker just enters the halfwave rectifier state, and correspondingly, the heating power of electric cooker promptly reduces half.So not only can keep the boiling of pot interior water, reduce the discharge capacity of water vapour, thin rice gruel can not overflow outside the pot yet, and saves energy greatly improves the mouthfeel quality of rice.

Fig. 2 is the circuit theory diagrams of energy-saving electric cooker;

Fig. 3 is the heat induction switch contour structures schematic perspective view at energy-saving electric cooker pot wall place.

Provide embodiment below in conjunction with accompanying drawing, and the utility model is described in further detail.

Present embodiment is to utilize interior pot (2), shell (3), pot cover (1), attaching plug (4), electric hot tray (5), magnet steel inductive switch (6) that existing electric cooker has and the heat induction switch parts such as (7) that link to each other with electric hot tray (5), and under the situation that does not change its structure and face shaping, between interior pot (2) outer wall and shell (3) inwall, pacify a heat induction switch (8) again.See Fig. 1.Consider that this heat induction switch (8) should keep excellent contact with interior pot (2) outer wall, with variations in temperature in the induction kettle observantly, fixation again, get and change conveniently, thereby the sheet metal (9) of this heat induction switch (8) box face one side is extended upward bending make it to form a hook-shaped, open a socket (10) in hook sheet metal (9) end, being fixed with connectors such as rivet or bolts is connected on the shell (3).Because the sheet metal (9) of bending has certain elasticity, and with heat induction switch (8) box face sheet metal be one, so when interior pot (2) was put into shell (3), heat induction switch (8) promptly was close on interior pot (2) outer wall, and can not form box face corner angle damage pot wall.The thin slice end has socket (10) in addition, makes it fixedly to get to change also to make things convenient for.See Fig. 3.

In order to make electric cooker in the process that heating is cooked, the power actual required with the process of cooking coincide, this heat induction switch (8) is modulated into and is being closure state below 97 ± 3 ℃, be off-state more than 97 ± 3 ℃, and the commutation diode (11) that is installed on shell (3) inner bottom part with this example is in parallel, and then be connected between magnet steel heat induction switch (6) and the heating wire (12).It is in parallel with magnet steel heat induction switch (6) to play insulation effect heat induction switch (7) as for another that links to each other with electric hot tray (5).These energy-conservation electric cooker circuit theory diagrams are seen Fig. 2.

When cooking, insert good attaching plug (4), connect power supply, press lower magnetic steel heat induction switch (6), the magnet head of magnet steel heat induction switch (6) promptly is adsorbed on interior pot (2) bottom, and entire circuit is closure state, and electric cooker is promptly started working with total power.When electric hot tray (5) temperature reaches 60～80 ℃, heat induction switch (7) automatic disconnection that links to each other with electric hot tray (5), but do not influence the work of electric cooker.When temperature continue to rise to make the pot in water temperature reach 97 ± 3 ℃, close on when seething with excitement or having seethed with excitement, be close to the also automatic disconnection of heat induction switch (8) on interior pot (2) outer wall, at this moment, the electric current of circuit promptly enters the halfwave rectifier state by commutation diode (11) in parallel, and corresponding, the heating power of electric cooker also reduces half, and the power after reducing with this is kept the boiling of pot interior thing, saves energy.When the meal boiled water do, when interior pot bottom temperature reaches 103 ± 2 ℃, the magnetic force of the magnet head of magnet steel heat induction switch (6) disappears, and leaves the bottom of a pan, switch disconnects, electric cooker just cuts off the power supply.When the temperature of meal drops to 60～80 ℃, play the heat induction switch (7) of insulation effect and just start working.

For the used commutation diode of the utility model (11), according to the voltage peak of civil power and the power of electric cooker, as long as select withstand voltagely more than 400 volts, the commutation diode of the heating power of its power consumption during greater than rectification in electric cooker gets final product.This example is selected two withstand voltage 400 volts, and rectification is carried out in the commutation diode parallel connection of power consumption 6A.

In sum, compared with the prior art the utility model has following advantages:

1. economize on electricity is significantly reliable. Cook congee and two of cooked rice every day by each household, measure through ammeter, an electric cooker can be saved 50～70 degree electricity in 1 year. Suppose that the whole nation has 50,000,000 family families to use energy-saving electric cooker, 25～3,500,000,000 degree electricity that then can economize on electricity national every year, its economic benefit and social benefit are all very remarkable.

2. can improve the quality of meal. Reducing of power, so that the degree of boiling reduces, the water on meal top just can in time be penetrated into the bottom, because water distribution is even, the meal that cooks just rare lower hard situation can not occur yet, thereby has improved quality and the mouthfeel of meal.

3. reduce pollution, improved security. Reducing of power not only can make water vapour reduce, and eliminate excessive thin rice gruel phenomenon, therefore, reduced the pollution to kitchen, pot body, the kitchen range top, can be because the thin rice gruel that overflows cause short circuit yet, and breaking out of fire, security has also improved.

4. made things convenient for use.Because the utility model is when cooking, the thin rice gruel that needn't flip also can not overflow, thus saved the trouble of looking after midway, bring great convenience to the user.
