The utility model is simple in structure, and three-dimensional heat insulation function is provided, and can keep heat insulation effect, holding temperature for a long time, and its three-dimensional insulation heat insulation effect is even, makes rice have mouthfeel, can not occur hot-spot and influence the problem of rice mouthfeel.
Description of drawings
Fig. 1 is the utility model circuit control principle figure.
Below by the drawings and specific embodiments the utility model is further described:
The specific embodiment
Three-dimensional heat-preservation electric rice cooker described in the utility model, comprise electric cooker body, stay-warm case, interior pot courage, circuit board 1, heating plate 3, top sensor 4, bottom sensor 5, top heater strip 6, sidepiece heater strip 7 and in be provided with the control display board 2 of microprocessor 21.Concrete structure is as follows:
Above-mentioned stay-warm case is located at electric cooker inside and is enclosed in outside the interior pot courage.As shown in Figure 1, be provided with in the above-mentioned control display board 2 and be used to the microprocessor 21 that receives, handle input signal and send control signal, and itself and circuit board 1 electrically connect; Above-mentioned top sensor 4 is located at the interior interior pot courage top of electric cooker and is electrically connected with circuit 1 plate; Above-mentioned bottom sensor 5 is located at the interior interior pot courage bottom of electric cooker and is electrically connected with circuit board 1; Above-mentioned top heater strip 6 is located at the interior interior pot courage top of electric cooker and is electrically connected with circuit board 1; Above-mentioned sidepiece heater strip 7 is located at the interior interior pot courage following side of electric cooker and is electrically connected with circuit board.
Send preservation and controlling signal to circuit board 1 control heat-generating disc 3, top heater strip 6 and sidepiece heater strip 7 after the temperature detection information of above-mentioned microprocessor 21 reception top sensor 4 and bottom sensor 5 and carry out the insulation heating.
Better embodiment of the present utility model is that the regulating and controlling temperature scope that above-mentioned top sensor 4 detects the insulation heating is 72 ℃ to 82 ℃; The regulating and controlling temperature scope that above-mentioned bottom sensor 5 detects the insulation heating is 60 ℃ to 70 ℃.Bottom sensor 5, top sensor 7 detected temperatures pass to information the microprocessor of controlling on the display board 2 21, judge by microprocessor 21 whether the temperature of test point can satisfy the setting value of program, send the power temperature of keeping test point to heat-generating disc 3, top heater strip 6, sidepiece heater strip 7 of information closing relay or controllable silicon by microprocessor 21 and satisfy the temperature of program setting as not satisfying then, if can satisfy the setting value relay, controllable silicon then disconnects not powering gives heat-generating disc 3, top heater strip 6, sidepiece heater strip 7 to power supply.
Further concrete, above-mentioned top sensor 4 is the top thermistor; Above-mentioned bottom sensor 5 is the bottom thermistor.
The utility model is by stay-warm case, heat-generating disc, top sensor, bottom sensor, the control display board, circuit board, the top heater strip, compositions such as sidepiece heater strip composition, it mainly is by bottom sensor, the top sensor detected temperatures passes to the microprocessor of control on the display board with information, whether can satisfy the setting value of program by the temperature of microprocessor judges test point, then sends the information closing relay by microprocessor or controllable silicon is powered to heat-generating disc as not satisfying, the top heater strip, the temperature that the temperature that the sidepiece heater strip is kept test point satisfies program setting (is that the regulating and controlling temperature scope that top sensor 4 detects the insulation heating is 72 ℃ to 82 ℃; The regulating and controlling temperature scope that above-mentioned bottom sensor 5 detects the insulation heating is 60 ℃ to 70 ℃), if can satisfy the setting value relay, controllable silicon then disconnects not powering gives heat-generating disc, top heater strip, sidepiece heater strip to power supply, thereby the long-time insulation of electric cooker can not caused, the jaundice of rice surface, the peripheral rice of pot " becomes withered " in " exsiccation ", and interior pot bottom rice jaundice forms " crispy rice " and keeps the former influential mouthfeel of rice.The utility model is simple in structure, and three-dimensional heat insulation function is provided, and can keep heat insulation effect, holding temperature for a long time, and its three-dimensional insulation heat insulation effect is even, makes rice have mouthfeel, can not occur hot-spot and influence the problem of rice mouthfeel.
