The specific embodiment
Embodiment:
The structural representation of frying in shallow oil roasting machine as shown in Figure 1, the schematic diagram of the utility model control device as shown in Figure 2, fry in shallow oil roasting machine and comprise the upper baking pan 1 that the food of cooking is heated, lower baking disk 2, being hinged on the lower baking disk 2 of upper baking pan 1 movable folding, the utility model control device includes upper baking pan heater circuit 3 that is arranged on the upper baking pan 1 and the lower baking disk heater circuit 4 that is arranged on the lower baking disk 2, leading to of control upper baking pan heater circuit 3 and lower baking disk heater circuit 4, the master control part 5 of disconnected state, the output of master control part 5 respectively with upper baking pan heater circuit 3, lower baking disk heater circuit 4 is electrically connected, and the input of master control part 5 is connected with the open angle that can detect upper baking pan 1 automatically, and control the angle detection module 7 that upper baking pan heater circuit 3 is switched on or switched off automatically according to detection angles.
Thereby select module 6 to be used for user's input and whether need conducting upper baking pan heater circuit and lower baking disk heater circuit demand upper baking pan and lower baking disk heating, as: simultaneously to upper baking pan, lower baking disk heating, separately upper baking pan is heated, separately to the lower baking disk heating etc., select module 6 to be two in the present embodiment and select key switch that upper baking pan 1, lower baking disk 2 are heated respectively: upper baking pan heater switch and lower baking disk heater switch.
Angle detection module 7 is used to detect the angle that upper baking pan is opened, in the present embodiment, angle detection module 7 is the switch that is connected with upper baking pan 1, as microswitch relatively more commonly used, magnetic reed switch etc., when upper baking pan 1 open angle is about 0 ° or about 180 °, be that upper baking pan 1 is closed or when opening fully, switch closure; Arbitrary non-complete open angle outside upper baking pan 1 is positioned at closure and opens fully, during as 100 °, switch disconnects.
Master control part 5 receives the signal of selecting module 6 and angle detection module 7 respectively, and, control the switching state of upper baking pan heater circuit 3 jointly according to the signal of selecting module 6 and angle detection module 7 according to the switching state of the signal controlling lower baking disk heater circuit 4 of selecting module 6.
The control flow chart of the utility model lower baking disk heating as shown in Figure 3, when the user operates the lower baking disk heater switch when it is disconnected, the desired signal of selecting module 6 lower baking disk not to be heated to master control part 5 inputs, master control part 5 disconnects according to this signal controlling lower baking disk heater circuit 4, stops lower baking disk being heated; When the user operates the lower baking disk heater switch when making it closed, select module 6 to the desired signal of master control part 5 inputs to the lower baking disk heating, master control part 5 heats lower baking disk 2 according to these signal controlling lower baking disk heater circuit 4 conductings;
The control flow chart of upper baking pan heating of the present utility model as shown in Figure 4, when the user operates the upper baking pan heater switch when it is disconnected, the desired signal of selecting 5 inputs of 6 pairs of master control part of module upper baking pan not to be heated, master control part 5 disconnects according to this signal controlling upper baking pan heater circuit 3, stops upper baking pan 1 heating; And operate the upper baking pan heater switch when making it closed as the user, select module 6 to the desired signal of master control part 5 inputs to the upper baking pan heating, if 7 whiles of angle detection module this moment are about 0 ° or about 180 ° to master control part 5 input upper baking pan open angles, it is the signal that upper baking pan is closed or open fully, master control part 5 will be controlled 3 conductings of upper baking pan heater circuit, upper baking pan 1 is heated, otherwise, master control part 5 control upper baking pan heater circuits 3 disconnect, and stop the heating to upper baking pan 1; Check the cooking status of food or in the process of food interpolation condiment, in time stop useless heating thereby open upper baking pan, initiatively help the user to reduce unnecessary power consumption, energy savings upper baking pan 1 the user.
Angle detection module 7 in the present embodiment also can adopt and be fixed on upper baking pan, the variable capacitance of the hinged place of lower baking disk, the fixed electrode of variable capacitance be packed in fry in shallow oil on the roasting machine motionless, the float electrode of variable capacitance is opened with upper baking pan, close and rotate, change thus between fixed electrode and the float electrode over against area, change capacitance, thereby the upper baking pan open angle that different capacitances is corresponding different, whether master control part 5 just can be judged the open mode of upper baking pan according to the capacitance signal of angle detection module 7 inputs like this, and correctly control and upper baking pan is heated.
Frying in shallow oil roasting machine and also can cancel and select module 6 in the present embodiment, what replace is preset with demand for heat in master control part 5, as upper baking pan, lower baking disk being continued heat etc.
Angle when upper baking pan is closed in the present embodiment is 0 °, angle in open is 180 ° fully, is the angle value under the perfect condition.In actual application, because cooking food is to the supporting role of upper baking pan, the various factors such as influence of horizontal plane, the scope of the open angle of upper baking pan 1 about 0 °, the scope as 0 °~5 ° generally also should belong to the upper baking pan closure state; Equally, the scope of the open angle of upper baking pan 1 about 180 °, the scope as 175 °~180 ° generally also should belong to the upper baking pan full open position.
As a kind of modification that present embodiment is fried in shallow oil roasting machine, angle detection module 7 also can be the combination of switch one and switch two, only just conducting under the situation of upper baking pan 1 closure of switch one, only just conducting under the situation that upper baking pan 1 is opened fully of switch two.Master control part 5 is receiving switch one and switch two during the signal of not conducting, and control upper baking pan heater circuit 4 disconnects, and stops the heating to upper baking pan 1.
