Abstract

The utility model relates to a heat insulation electronic rice cooker, which comprises a cooker body, a heating plate, a temperature limiter, a heat retainer, an overtemperature fuse, etc. An automatic power transfer switch K2 is connected in parallel beside a diode D1, and the temperature control is in a switching state with the temperature below 99 DEG to 95 DEG. When the utility model is used for cooking the porridge or the soup, the power automatic transfer switch can do automatic working after the transfer switch is pushed without changing the gear of the transfer switch by the user guarding beside the utility model. The utility model has the advantages of labor saving, time saving, electricity saving, reasonable design, simple circuits, low cost, and convenient use, so the utility model is popular.

Description

Heat preserving type electronics electric cooker
The utility model belongs to a kind of heat preserving type electronics electric cooker.
At present, heat preserving type electronics electric cooker has various, for example 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., have insulation, energy-conservation and pot congee, multiple functions such as pot meal, Baoshang, and the electric cooker optimal selection is computer control, but, be not easy to popularize because price is higher.What price was more cheap is the heat preserving type auto-electric cooker using pottery, but because of line construction is simple, power can not be regulated because of needs, and energy-saving effect is not good, neither be very desirable.
The purpose of this utility model provides a kind of heat preserving type electronics electric cooker, on the ordinary electronic electric cooker that includes pot body, heating board, temperature limiter, warmer, overheating fuse, set up the power automatic change-over, temperature control is set in 99 ℃ to being in on-state below 95 ℃, if need Baoshang or pot congee, only need once push the pass aside, the user needn't keep the gear of alteration switch aside, and is worked automatically by the power automatic change-over, has so not only saved trouble but also has saved time and power saving.
The utility model is by in the ordinary electronic electric cooker circuit that contains pot body, heating board, temperature limiter, warmer, overheating fuse, at 1 K2 of diode D1 next door power automatic change-over in parallel, this switch adopts the temperature control switch, temperature control is set in 99 ℃ to being in on-state below 95 ℃, import 220 volts of alternating currents if surpass design temperature, this switch cuts off electric current automatically, and electric current reaches small-power low baking temperature Baoshang or pot congee to heating board input low-voltage DC after by diode D1 halfwave rectifier.
The utility model is reasonable in design, and circuit is simple, and cost is low, easily promotes, and is easy to use, very popular with users.
Description of drawings:
Fig. 1 is the utility model line map;
Fig. 2 is a primary electron electric cooker line map.
The utility model is improved on primary electron electric cooker circuit, and as shown in Figure 2, former circuit is by the input of K switch control power supply, when K met D4 and cooks grade, the indicator lamp of cooking was bright, this electric cooker rated power 700W, what flow through heating board is the 220V alternating current, and consumed power is 700W; When switch connect the D3 poridge cooking gear, pot congee indicator lamp was bright, and the 220V alternating current becomes low-voltage DC and supplies with heating board after diode D1 rectification, heating board power consumption 140W, and the shortcoming of above-mentioned circuit is that power can not be changed automatically, must manually-operated when promptly 700W transfers 140W to.The congee or when stewing if the user stews is pressed poridge cooking gear very naturally, but because of input power is 140W, just can be boiled for a long time.If the user presses poridge cooking gear 140W after boiling by grade 700W wait of cooking earlier again, operation not only saves time but also energy-conservation like this, but the user must keep operation aside, so just wastes user's time and efforts.The utility model is according to these shortcomings of primary electron electric cooker and improved, as shown in Figure 1: mainly be just can at 1 K2 of primary electron electric cooker circuit diode D1 next door power automatic change-over in parallel, if need Baoshang or pot congee, only need switch is dialled to poridge cooking gear, the user needn't keep the gear of alteration switch aside, and work automatically by the power automatic change-over, because when first input power 700W boils, be automatically converted to low baking temperature power 140W, pot lid needn't be opened, water evaporates is circulation in pot, and power consumption is little, and the soup loss is minimum.By grade 700W that cooks, boiling needs half an hour, poridge cooking gear 140W stewes 2 hours meters slowly, 700W * 0.5+140W * 2=630W time=0.63 degree, once calculate by boiling soup every day, the annual electricity consumption of each family is 0.63 * 365=229.95 degree, again by the whole nation 300,000,000 family's power consumptions every day, 0.63 degree * 3 hundred million=1.89 hundred million degree, and use common electric cooker to have saved 3.36 hundred million degree with 5.25 hundred million degree.

Claims (1)

1, a kind of heat preserving type electronics electric cooker, by including in the ordinary electronic electric cooker circuit that pot body, heating board, temperature limiter, warmer, overheating fuse etc. form, it is characterized in that: at 1 K2 of diode D1 next door power automatic change-over in parallel, this switch adopts the temperature control switch, temperature control is set in 99 ℃ to being in on-state below 95 ℃, import 220 volts of alternating currents, if surpass design temperature, this switch cuts off electric current automatically, and electric current reaches small-power low baking temperature Baoshang or pot congee to heating board input low-voltage DC after by diode D1 halfwave rectifier.
