Accompanying drawing explanation
Fig. 1 is the utility model circuit diagram.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is further described:
As shown in Figure 1, a kind of electronic temperature-sensing type energy-saving prevention excessive pressure electric cooker, comprise power circuit, heater element H, working power indicating circuit and controller B, be provided with the temperature controller of three different particular job temperature in a power, namely be incubated temperature controller 11, heating temperature control device 12 and overheated temperature controller 13, described insulation temperature controller 11, heating temperature control device 12 and overheated temperature controller 13 are all electrically connected with controller B;
When electrically pot is in keeping warm mode, when insulation temperature controller 11 monitors heater element H temperature lower than insulation temperature controller 11 setting value, control heater element H energising by controller B, on the contrary then power-off;
When electrically pot is in boiling state, when heating temperature control device monitoring temperature of heating elements is higher than heating temperature control device setting value, control heater element power-off by controller;
Under electric pot is in running order, when overheated temperature controller monitoring temperature of heating elements is higher than overheated temperature controller setting value, control heater element power-off by controller;
Also comprise diode, diode is in parallel with heating temperature control device, connects in a power, be also provided with overvoltage protection contact in a power after described diode and the parallel connection of heating temperature control device.
Described insulation temperature controller particular job temperature is the arbitrary numerical value in 90 DEG C ~ 98 DEG C.
Heating temperature control device particular job temperature is the arbitrary numerical value in 80 DEG C ~ 86 DEG C.
Overheated temperature controller particular job temperature is the arbitrary numerical value in 150 DEG C ~ 170 DEG C.Heater element is heat-generating disc.
Certainly, the power switch K for controlling whole power circuit closure or openness and the fuse F for the protection of power circuit trouble free service is also provided with in a power.
Utility model works flow process will be described below:
When using the utility model electric rice cooker meal, first switch on power K switch, electric current forms loop through the protection contact S of anti-overvoltage, insulation temperature controller 11 and the overheated temperature controller 13 of high temperature-proof, heat-generating disc H and parallel connection diode D together and heating temperature control device 12, now heat-generating disc enters heating work, and in power supply indicator, big fire indicator lamp is bright simultaneously, low baking temperature indicator lamp is bright, insulation indicator lamp extinguishes; When the operating temperature that heating temperature control device 12 detects heat-generating disc reaches its particular job temperature 80 DEG C ~ 86 DEG C (when being such as 83 DEG C), now heating temperature control device 12 open circuit forms open circuit, the electric current of whole circuit is forced to flow to the diode in parallel with it, thus under the effect of diode, voltage is down to the half of original voltage, the heating power of its electric hot tray is also down to original half and is continued heating, effectively can give prominence to energy-saving spill-prevention effect like this, now in power supply indicator, big fire indicator lamp extinguishes, low baking temperature indicator lamp is bright, be incubated indicator lamp extinguishing; When being heated to insulation temperature controller 11 particular job temperature 90 DEG C ~ 98 DEG C with low baking temperature (when being such as 95 DEG C), insulation temperature controller 11 is cut off the electricity supply circuit, electric hot tray is quit work, now in power supply indicator, big fire indicator lamp extinguishes, low baking temperature indicator lamp extinguishes, insulation indicator lamp is bright, like this, electric cooker enters keeping warm mode, about crosses and just can have a meal for more than ten minute.
In electric cooker insulating process, along with the impact of ambient temperature constantly reduces temperature, when temperature is down to below a certain specified temp (when being such as 95 DEG C), insulation temperature controller 11 is closed forms loop, and now electric hot tray is heated in low-grade fever state; When temperature is more than 95 DEG C, insulation temperature controller 11 disconnects again control electric hot tray and quits work, so repeatedly, to reach the object of electric cooker insulation.
The process of pot congee is identical with pot meal process, does not describe at this.
When electric pot course of work to be incubated because certain reason occurs overtemperature temperature controller 11 malfunctioning time, the overheated temperature controller 13 of high temperature-proof measures electrically stews when arriving its specific operating temperature (such as its specific operating temperature value is 165 DEG C), so overheated temperature controller 13 cuts off current supply circuit automatically, power circuit is made to be in open-circuit condition, electric hot tray is made to stop heating, effective like this effect reaching high temperature-proof.
When the anti-overpressure means of machinery set on each temperature-sensing element and pot face of electrically stewing is all malfunctioning; pressure cooker is pressed to the feeler lever below it downwards by the excessive pressure of pressure cooker; the protection contact S being touched anti-overvoltage by feeler lever carries out work, and heat-generating disc is quit work, to reach the object of anti-overvoltage.
Described insulation temperature controller 11, heating temperature control device 12 and overheated temperature controller 13 can be arranged on pot any position, middle level or be arranged on any position bottom the following middle level of electric hot tray; best set-up mode is insulation temperature controller 11, heating temperature control device 12 is installed in and electrically stews on the periphery of middle level, and the protection contact S of overheated temperature controller 13 and anti-overvoltage is installed in side under electric pot.
Also by the utility model structural framing for heating appliances such as pots, so also can should be within protection domain of the present utility model.
