Embodiment
Refer to Fig. 1, Fig. 1 is the internal structure vertical view of the utility model embodiment electric oven power governor.Power governor comprises the switch module (2 and 3), the Metallic rod 4 that are arranged in housing 1, be fixed on rotating shaft on (not indicating in figure) cam pack 5, driven subassembly 6 and heater 7, heater 7 is fixed in Metallic rod 4, and switch module comprises mains switch 2 and power regulating switch 3.
Wherein, Metallic rod 4 is bimetallic lever, and it is to have by two kinds (or multiple) composite material that the metal or alloy constituent element layer of different heat expansion coefficient combines securely.The layer that a constituent element layer in bimetallic has low thermal coefficient of expansion is passive layer; The layer that another constituent element layer has high thermal coefficient of expansion is active layers.The thermal coefficient of expansion of each constituent element of bimetallic is different, and when variations in temperature, the expansion of each constituent element or amount of contraction are different, and making as a whole bimetallic element will bend.
Wherein, driven subassembly 6 is followed the rotation of cam pack 5 and is moved, to control connection and the disconnection of mains switch 2; Metallic rod 4 is followed the rotation of cam pack 5 and is rotated, with the time of connection and the disconnection of power ratio control by-pass cock 3.
In the present embodiment, heater 7 is fixed in Metallic rod 4, when heater 7 energising heating, and Metallic rod 4 temperature distortions, and then power regulating switch 3 is switched on or switched off, so that power governor is exported certain power.Metallic rod 4 is followed the rotation of cam pack 5 and is rotated, when cam pack 5 rotates different angles, and the corresponding rotation of Metallic rod 4, and then make the connection of power regulating switch 3 and the asynchronism(-nization) of disconnection, the ratio of the power of power governor output is also different.The cam pack 5 of the present embodiment matches with the power stage ratio of power ratio control adjuster with heater 7 and Metallic rod 4, higher than the degree of regulation of the power governor of prior art.
In addition, general mains switch 2 is thinner, because cam pack 5 is controlled connection and the disconnection of mains switch 2 by driven subassembly 6, avoids cam pack 5 to contact with the direct of mains switch 2, and then avoids the friction between cam pack 5 and mains switch 2.
Particularly, incorporated by reference to consulting Fig. 2 and Fig. 3, cam pack 5 comprise main cam 51 and be arranged at main cam 51 top from cam 52.Mains switch 2 and power regulating switch 3 all have fixed terminal and movable terminal, and its fixed terminal is all fixed on housing 1, and the movable terminal of mains switch 2 is fixed on driven subassembly 6, driven subassembly 6 with from cam 52 lateral edge, coordinate.
One end of Metallic rod 4 is fixed on housing 1 by revolution shell fragment 11, and the other end is formed with major branch 41 and compensation branch 42, one end and tangent cooperation of main cam 51 lateral edge of compensation branch 42, and follow the rotation of main cam 51 and rotate.Heater 7 is fixed on major branch 41, the movable terminal of power regulating switch 3 and major branch 41 butts, and by the movable terminal of heater 7 power ratio control by-pass cockes 3 and the fixed terminal connecting and disconnecting of power regulating switch 3.
Wherein, can, by adopting the mode of rivet and spring that heater 7 is fixed on major branch 41, also can adopt other fixed form that heater 7 is fixed on major branch 41.After the fixed terminal and movable terminal connection of power regulating switch 3, heater 7 produces a large amount of heats when energising, major branch 41 temperature distortions, fixed terminal and the movable terminal of power regulating switch 3 are disconnected, heater 7 stops heating, and major branch 41 is cooling and restore to the original state, and power regulating switch 3 is connected again, so circulation, fixes the ratio of power stage.
Wherein, it is adjacent that the edge of main cam 51 has the first depressed part 511 and lug boss 512, the first depressed parts 511 and lug boss 512, has the second depressed part 521, the second depressed parts 521 corresponding with the position of the first depressed part 511 from the edge of cam 52.Driven subassembly 6 comprises driven sliding block 61 and elastic component 62, and elastic component 62 can be spring or metal clips etc.Driven sliding block 61 with from cam 52 lateral edge, coordinate, the movable terminal of mains switch 2 is fixed in driven sliding block 61, and follows from the rotation of cam 52 and move.When driven sliding block 61 compression elastic piece 62, the fixed terminal of the movable terminal of mains switch 2 and mains switch 2 is connected; When driven sliding block 61 and elastic component 62 lower time in the raw, the fixed terminal disconnection of the movable terminal of mains switch 2 and mains switch 2.
Wherein, from cam 52, main cam 51 and driven sliding block 61, be working of plastics.
Further, when driven sliding block 61 is placed in the position of the second depressed part 521, the movable terminal of mains switch 2 and fixed terminal disconnect, and one end of compensation branch 42 is placed in the position of the lug boss 512 of main cam 51, the now movable terminal of power regulating switch 3 and fixed terminal disconnection; When driven sliding block 61 is placed in except the position of the second depressed part 521, while being placed in other positions from the lateral edge of cam 52, the movable terminal of mains switch 2 and fixed terminal are connected, one end of compensation branch 42 is placed in main cam 51 other positions except the position of lug boss 512, and now the movable terminal of power regulating switch 3 and fixed terminal are connected.
