Below in conjunction with accompanying drawing, main element employing electromagnetic relay one embodiment with regard to automatic controller is described further the utility model.

Fig. 1 is the structural map of multifunctional automatic electric heat pot embodiment of the compound end.

Fig. 2 is the electrical schematic diagram of the utility model automatic controller.

Multifunctional automatic electric heat pot of the compound end shown in Fig. 1 uses on civil power.Pot cover (1) is to make with stainless steel.Pot body (2) also is to make with stainless steel, comes the storage usefulness of cooking.Gas skirt (3) is made with pottery, and band is pricked on the following diapire, is placed on a pot body (2) lining and is used as chafing dish.Composite bed (5) with pot body and electric hot tray (or electrothermal tube) compound securely be one.The heat that electric hot tray (6) produces conduction is uniformly given bottom of pot body everywhere.Alumina silicate fibre (7) is filled out below electric hot tray (6), loses with the downward biography that prevents heat.Compound push switch (10) and indicator light switch (11), (19), (18) and indicator lamp (8) are housed on the base (9).Indicator light switch (11) control 300W electrothermal tube power, (19) control 600W electrothermal tube power, (18) control 900W electrothermal tube power can select different with the requirement of time speed use according to the kind of cooking food.Compound push switch (10) has three effects: can make electromagnetic relay (13) connection, self-locking and the cut-out of automatic controller circuit.After rice was carried out, deenergization stopped to heat electromagnetic relay (13) by thermostat (17).After thermostat (12) can make meal carry out, automatic constant-temperature was at 70 ℃ and not cool.Indicator lamp (8) is indication automatic controller and constant-temperature circuit break-make.When pot fry, when fried temperature surpasses 250 ℃, thermostat (20) is just automatically with circuitry cuts (lamp on the indicator light switch goes out), no longer heating.But in a single day temperature drops to when being lower than 250 ℃, recovers automatically again to connect circuit (lamp on the indicator light switch is bright), reheats.

In Fig. 2, the circuit in the dotted line is a circuit of the present utility model, and the outer circuit of dotted line is former pot circuit.Working condition with regard to circuit of the present utility model (figure is a duty) is as follows: the city is electrically interposed in power supply (23) and protective earth (22), clicks compound rotary switch (10), the group normally opened contact is connected.At this moment, electromagnetic relay (13), by its next group contact and thermostat electrothermal relay) the contacting circuit of (17) and self-locking keeps, and closure by its last one group of contact the time, make by the circuit of the manually operated 900W electrothermal tube of indicator light switch (18) and connect (because of last one group of contact of electromagnetic relay and on the circuit of 900W electrothermal tube), indicator lamp (8) is bright, produces the bottom that heat comes heating kettle body (2).As what do inside the pot is rice, when the water in the rice dryouies, thermostat (17), rising (170 ℃) because of cooking bottom temperature, contact by its control disconnects, electromagnetic relay (13) no longer self-locking keeps, controlled on, following two groups of contacts all disconnect simultaneously, indicator lamp (8) is no longer bright, 900W electrothermal tube circuit by indicator light switch (18) control also is disconnected, and has stopped the generation heat, and at this moment rice is just in time cooked ripe, circuit also is in keeping warm mode automatically, be that thermostat (12) is started working, it can make the meal automatic constant-temperature of doing in the pot at 70 ℃, and it is not cool to have a meal for a long time for people.As what endure in the pot is congee, can manually left-handedly click compound push switch (10) after getting well, and makes next group often close the contact and disconnects, at this moment, the no longer self-locking maintenance of the circuit of electromagnetic relay (13), the same principle, controlled 900W electrothermal tube is no longer heated, and circuit is in keeping warm mode automatically.As what iron in the pot is the shelled peanut of cake and baking, at this moment can first dextrorotation click compound push switch (10), the circuit of electromagnetic relay (13) not only self-locking keeps, and compound push switch (10) also carries out the self-locking (close by often opening often to become its last one group of contact) of itself.Like this, the temperature in the pot remains on 170 ℃ by the effect of thermostat (17), and it can iron cake automatically and be baked shelled peanut.Circuit beyond the dotted line is former pot circuit, and its third gear power still uses by artificial selection, not influenced by any of its automatic controller, still can keep original and fries in shallow oil, fry, explode, boil in a covered pot over a slow fire, stew, steam, boil, function such as chafing dish.Excessive when heat, it is too high when surpassing 250 ℃ to heat up, and is disconnected by the contact of thermostat (20) control, the circuit of every grade of power all can be cut off, and no longer heating as long as the temperature in the pot drops to when being lower than 250 ℃, promptly automatically restores to normal.(21) be the overtemperature prote device, in use, as anomaly occur and can cut off the power supply rapidly that the unlikely damage of pot has been lived in protection effectively, at this moment, can use after should changing the overtemperature prote device.

Because multifunctional automatic electric of compound end heat pot, increased automatic controller, like this, just further enlarge and improved the function of use and the automatic controlling level of former pot, thus the convenience that has guaranteed the quality of its food of doing and saved people's time and used.
