Abstract

The utility model relates to an automatic overflow preventing and heat insulation electronic rice cooker with energy saving. A set of slight fire state indicating lamps are additionally arranged in existing automatic overflow preventing and heat insulation electronic rice cookers with energy saving. The lines of existing automatic overflow preventing and heat insulation electronic rice cookers with energy saving are improved to make a user can conveniently observe liquid entering a slight fire state or not after the liquid is boiling to avoid the phenomenon that firepower can not be controlled caused by a function select switch is pressed on a full power gear to make soup overflow. The utility model has the advantages of reasonable design, simple lines, low cost, and convenient operation.

Description

Automatic energy saving anti-overflow heat preserving type electronics electric cooker

The utility model belongs to a kind of automatic energy saving anti-overflow heat preserving type electronics electric cooker.

At present, heat preserving type electronics electric cooker has respectively and various kinds, for example timing automatic energy-conservation, the magnetization of patent 97246137.X automatic energy saving heat preserving type electronics electric cooker, patent 98233650.0, heat preserving type electronics electric cooker etc., all have insulation, the energy-conservation and congee of cooking, stew, multiple function such as stew, overflow easily when particularly cooking congee but cook, automatically regulate to low baking temperature though be provided with, be difficult for observing the low baking temperature state that whether entered by big fire.

The purpose of this utility model provides a kind of automatic energy saving anti-overflow heat preserving type electronics electric cooker, in former automatic energy saving heat preserving type electronics electric cooker circuit, set up one group of low baking temperature status indicator lamp, be convenient to whether enter the low baking temperature state after observation is boiled, and circuit improved avoid functional select switch by on the position of total power indication and cause firepower not control, soup is overflowed.

The utility model comprises pot body, heat-generating disc, temperature limiter, warmer, elasticity temperature detect switch (TDS) and indicator lamp etc., and the AN that pushes button, electric current are divided into two strands of electric currents after by overheating fuse RD, one by key switch AN through heat-generating disc R ₁, another strand electric current diode D that flows through ₂And indicator lamp ZSD ₁Lamp is bright, and R again flows through ₃With process heat-generating disc R ₁Electric current converge after again through elasticity temperature detect switch (TDS) WK ₂Form the loop, the total power input; Elasticity temperature detect switch (TDS) WK ₂Automatically cut off main circuit, power supply is then by being connected in parallel on elasticity temperature detect switch (TDS) WK ₂The diode D at two ends ₁Become low-voltage dc power supply input heat-generating disc R after the halfwave rectifier ₁Power supply is at WK simultaneously ₂After the cut-out, big fire indicator lamp ZSD ₁Extinguish, diode D flows through ₂Electric current be forward dc, at D ₁Acting in opposition under refuse conducting, this moment low baking temperature indicator lamp ZSD ₂Continue shinnyly, forward current passes through resistance R ₄After low baking temperature indicator lamp ZSD ₂Diode D again flows through ₃, form the loop through key switch AN and fuse RD; Temperature limiter XW loss of excitation after temperature reaches Curie-point temperature under the effect of low-voltage direct small-power, button AN cuts off the power supply automatically, low baking temperature indicator lamp ZSD ₂Extinguish, electric current divides two strands behind overcurrent fuse RD, stock-traders' know-how insulation resistance R ₂Flow to heat-generating disc R ₁Again through D ₁Enter keeping warm mode, be incubated indicator lamp ZSD this moment ₃Bright, electric current through fuse RD again through resistance R ₅Insulation indicator lamp ZSD flows through ₃Through heat-generating disc R ₁Form the loop.

Timer SK is housed on main circuit, and the AN that pushes button, electric current be through overheating fuse RD, through key switch AN, by timer SK again through heat-generating disc R ₁, form the loop through elasticity temperature detect switch (TDS) WK.

The utility model is reasonable in design, and circuit is simple, is convenient to during use observe, operation, cooks, cooking congee is difficult for overflowing, and cost is low, easily promotes the use of.

Description of drawings:

Fig. 1 is the utility model line map (not timing);

Fig. 2 is the utility model line map (regularly).

As shown in Figure 1, connect the 220V alternating current, AN presses with button, and electric current is by overheating fuse RD, by the heat-generating disc R that flows through behind the key switch AN ₁, pass through elasticity temperature detect switch (TDS) WK again ₂Form the loop, be total power input, big fire indicator lamp ZSD this moment ₁With low baking temperature indicator lamp ZSD ₂Simultaneously bright, the effect during this state is that rice, soup or congee are boiled fast, to save time.When food reaches 99-90 ℃ in pot, elasticity temperature detect switch (TDS) WK ₂Automatically cut off main circuit, power supply is then by being connected in parallel on the diode D at elasticity temperature detect switch (TDS) two ends ₁Become low-voltage dc power supply input heat-generating disc R after the halfwave rectifier ₁Carry out the state that the small-power low baking temperature is cooked, big fire this moment indicator lamp ZSD ₁Automatically extinguish, diode D flows through ₂Electric current be forward dc, at D ₁Acting in opposition under refuse conducting, this moment low baking temperature indicator lamp ZSD ₂Continue shinnyly, temperature limiter XW loss of excitation button AN under spring action takeoffs automatically when reaching 100.5 ℃ to 104.5 ℃ Curie-point temperature behind the ripe solid carbon dioxide of meal when temperature reaches 100 ℃.Be incubated resistance R this moment ₂Start working, because R ₂With heat-generating disc R ₁Series connection insulation electrical power is about 40W, temperature can be controlled at highlyer about 45 ℃ than normal temperature, is incubated indicator lamp ZSD this moment ₃Shinny, low baking temperature indicator lamp ZSD ₂Extinguish.If pot congee or stew basically equally boils after 100 ℃ with above process,, think and when mouthfeel is suitable button has been dialled voluntarily according to hobby to food soft or hard degree.As shown in Figure 2, adopt timer, then the school transfers the required time to control automatically in advance, and is so just convenient.
