5, embodiment:
Embodiment:
Circuit theory diagrams of the present invention as shown in Figure 1, include microcomputer controller IC, relay R, the input switch K1 of pilot relay R closure and input switch K2, pilot relay R disconnects, and the normally closed switch K3 of the normally closed switch K4 of setting heating location and setting outflow location, input switch K1 wherein, input switch K2, normally closed switch K3, normally closed switch K4 is connected with the input end of microcomputer controller IC, the output terminal of microcomputer controller IC is connected with relay R, the end of motor T is connected with the live wire L of power supply, and the other end of motor T is connected with the zero line N of power supply by the contact of relay R.In the present embodiment, above-mentioned normally closed switch K 3 and normally closed switch K4 are normally closed microswitch.Above-mentioned input switch K1 and input switch K2 are keyswitch.
Above-mentioned microcomputer controller IC is single-chip microcomputer or Programmable Logic Controller.In the present embodiment, above-mentioned microcomputer controller IC is a single-chip microcomputer.
Because microswitch K3 is normally closed switch, when the user puts raceway in the stove to food supporting frame, when food supporting frame shifted out the outer position of setting of furnace chamber, food supporting frame was pushed down K switch 3, and K switch 3 disconnects, and food supporting frame stops to move outside furnace chamber.In like manner, because microswitch K4 is a normally closed switch, when food supporting frame moved to the heating location of setting in the furnace chamber, food supporting frame was pushed down microswitch K4, and microswitch K4 disconnects, and food supporting frame stops to move in furnace chamber again.
In order to ensure the security of using,, also be connected with protective tube Fuse on above-mentioned motor T and the circuit that the live wire L of power supply is connected in order to avoid circuit burns out members such as motor when being short-circuited.
The power supply of above-mentioned microcomputer controller IC is connected with the secondary coil of transformer L, and the primary coil of transformer L is connected between the zero line N of the live wire L of power supply and power supply.
The present invention is contained in the cooking food stove and accessorys such as micro-wave oven, baker and uses, and the loop of establishing through " power supply L line, protective tube Fuse, motor T, relay R, power supply N line " formed is loop L.When the user after putting food on the food supporting frame, food supporting frame need be delivered to furnace chamber the inside and go, then operate as follows:
Press into button K1, microcomputer controller IC receive need be in furnace chamber the instruction of mobile food supporting frame, pilot relay R closure, then loop L conducting, motor T entry into service, food supporting frame begins to move.When food supporting frame arrives microswitch K4 place, touch K4, K4 disconnects, microcomputer controller IC detects the signal that K4 disconnects, and judges that food supporting frame has arrived desired location in the furnace chamber, and just pilot relay R disconnects, then loop L disconnects, and motor T shuts down, and food supporting frame stops to move.
After food cooking has been got well, the high temperature food bearing support in the stove need be shifted out, then operation so that get food
As follows:
Press out button K2, microcomputer controller IC receive need be outside furnace chamber the instruction of mobile food supporting frame, pilot relay R closure, then loop L conducting, motor T entry into service, food supporting frame begins to move.When food supporting frame arrives front position-arresting microswitch K3 place, touch K3, K3 disconnects, microcomputer controller IC detects the signal that K3 disconnects, judge that food supporting frame has arrived the outer desired location of furnace chamber, just pilot relay R disconnects, and then loop L disconnects, motor T shuts down, and food supporting frame stops to move.
The control of the present invention and magnetron as the circuit theory diagrams of one as shown in Figure 2, the shared microcomputer controller IC of the present invention of the control of magnetron.
