Abstract

The utility model relates to an automatic energy saving and heat preservation electronic rice cooker, which comprises a heat preservation automatic electric cooker circuit. The heat preservation automatic electric cooker circuit is composed of a cooker body, a heating plate, a temperature limiter, a heat preserver, an over temperature fuse, etc. A power automatic transfer switch WK (2) is connected in parallel beside a series diode D. The temperature control of the WK (2) is below 99 DEG C to 90 DEG C in an on-state, and when the temperature is over 99 DEG C to 90 DEG C, the ac power supply is cut off while the low voltage direct current is input by the half-wave rectification of the series diode D. The switch WK (2) is arranged on the inner wall of a cooker casing and can be contacted with the cooker liner. The utility model has the advantages of reasonable design, simple circuit, low cost, convenient operation, and high popularity.

Description

Automatic energy saving heat preserving type electronics electric cooker

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

At present, heat preserving type electronics electric cooker has various, and side such as the full-automatic heat-preservation electric rice cooker of patent 95243315.X temperature control, patent 96207561.2 have the grill pan of automatic heat preserving circuit arrangement etc., has insulation, energy-conservation and pot meal, multiple functions such as pot congee, Baoshang.And use the electric cooker optimal selection is computer control, but because price is higher, is difficult for popularizing, and price more cheap be the heat preserving type auto-electric cooker using pottery, but simple because of line construction, power can not be regulated because of needs, often a power uses the end, does not have energy-saving effect.If adopt the manually size of control power, just need personnel to keep an eye on, not only bothered but also can not accurately grasp the time of transfer power switch.

The purpose of this utility model provides a kind of automatic energy saving heat preserving type electronics electric cooker, on the basis of former heat preserving type auto-electric cooker using pottery, set up diode and power automatic change-over, temperature control is set in 99 ℃--be in on-state below 90 ℃, only need once to press switch during use, electric cooker both can be worked automatically by the power automatic change-over, automatically regulate by big fire to low baking temperature as required, both can reach the result of use of existing computer control electric cooker, can overcome the not good shortcoming of general electric cooker energy-saving effect again, reach and save time and purpose of power saving.

The utility model is by containing in the heat preserving type auto-electric cooker using pottery circuit that pot body, heating board, temperature limiter, warmer, overheating fuse etc. form power automatic change-over WK in parallel by the series diode D ₂, this switch adopts temperature control elastic switch, is installed in the position of pot shell inwall contact pot courage, also can be installed on the position that loam cake can touch pot inner cap; WK ₂Temperature control be set in 99 ℃ and be in on-state below-90 ℃, import 220 volts alternating currents this moment, surpass 99 ℃ and then cut off the AC power of being imported, this moment, power supply was imported low-voltage DC to heat-generating disc after by diode D halfwave rectifier.

The utility model is reasonable in design, and circuit is simple, and cost is low, easily promotes the use of, and not only saves time but also economize on electricity, and is very popular with users.

Description of drawings:

Fig. 1 is the utility model line map;

Fig. 2 is former heat preserving type auto-electric cooker using pottery line map;

Fig. 3 is the utility model temperature detect switch (TDS) scheme of installation.

Below in conjunction with accompanying drawing the utility model is elaborated:

As shown in Figure 2, former circuit presses the button AN, indicator lamp ZSD by the input of press button AN control power supply ₁Bright, establishing this electric cooker rated power is 700W, jumps superly, or well-done from pressing the AN button food that begins to stew to the pot to the ripe button of meal from beginning to press AN, and power is immovable always.

The utility model is improved on the basis of former heat preserving type auto-electric cooker using pottery circuit.As shown in Figure 1, power automatic change-over WK of series connection ₂, this switch adopts the temperature control elastic switch, is set in 99 ℃ and is in on-state below-90 ℃.During use shift knob AN is pressed, import 700W power, power automatic change-over WK when boiling earlier ₂Automatically, cut off AC power, power supply then carries out 300W small-power low baking temperature and cooks by becoming low-voltage dc power supply input heat-generating disc after the diode connected in parallel D halfwave rectifier, and the ripe back of meal button takeoffs.If cook congee or stew, also be that AN is pressed, input 700W AC power, during boiling, WK ₂Automatically cut off AC power, and the input of the 300W direct current after diode D halfwave rectifier heat-generating disc, the small-power low baking temperature state that stews, the soft or hard degree of food can be according to each one required difference, and select time pulls up button voluntarily and gets final product.

As shown in Figure 3, described power automatic change-over (3) is the temperature control elastic switch, and any one can contact on the position of pot courage (2) can be installed in electric cooker pot shell (1) inwall.During use, the courage (2) of will stewing is put into pot shell (1), pot courage contact-making switch (3), and along with the continuous rising of food temperature in pot courage, when reaching design temperature, switch (3) cuts off AC power automatically.Described power automatic change-over (3) also can be installed in loam cake (4) can touch on any one position of pot lid (5), cover pot when cover, pot lid (5) in switch (3) contact, the interior temperature of induction pot.Described temperature control elastic switch is a standard component, all can buy on the market.

Because the utility model transfers low baking temperature power 300W to after boiling the soup boiling automatically, pot lid needn't be opened, and water evaporates is circulation in pot, and power consumption is little, and the moisture content loss of soup is few, is difficult for boiling dry.Calculated in 3 hours by stewing every day, the power consumption of automatic energy saving electronics electric cooker is: boil and stew 2.5 hours meters half an hour slowly, 700W * 0.5+300W * 2.5=1.1 degree, the heat preserving type auto-electric cooker using pottery then is 700W * 3=2.1 degree, calculate by this, spend than traditional electric cooker economize on electricity 1 as stewing with the utility model electric cooker every day, as promote the use of, the whole nation 300,000,000 families are calculated, every day saves energy 300,000,000 degree.
