Abstract
The utility model relates to a mechanical bistable force-controlled trigger power switch with a memory function, which mainly comprises a micro-motion flickering switch, an abnormity elastic lever, an abnormity steel wire lever, an adjustable limiter, adjustable screws, an EF contact point button, a limiter adjustable rotary button, a support and an outer pot. The switch not only can adjust temperature and pressure in a stepless mode, but also can switch on a relevant auxiliary power supply while automatically cutting off heating power supply of a main circuit when cooking is finished. The utility model has the advantages of short control stroke, fast working speed of contact points, high reliability, convenient installation and debugging, low cost and wide purpose.
Description
It is the mains switch of electric heating pressure cooking appliance that the utility model relates to, and particularly a kind of mechanical bistable state power control triggers mains switch.
The switch that is used at present on the cooking apparatus has multiple, " the multifunctional self-regulating energy-saving norishing pot " of CN93216338.6 for example, " the multifunctional self-regulating energy-saving norishing pot " of CN95220298.0, " multifunctional self-regulating elastic pressure pot " with CN96218620.7, and CN96106423.4 " safety auto-controlled energy-saving norishing pot ", employed " force switch " device is all not too convenient, and complex structure etc.
The purpose of this utility model provides a kind of mechanical bistable state power control and triggers mains switch, and this switch not only can stepless temperature-regulating, pressure regulation, and when culinary art finishes, when can cut off the main circuit heating power supply automatically, connect relevant accessory power supply, thereby reach the requirement of further automation.
The purpose of this utility model realizes by following proposal, mechanical bistable state power control of the present utility model triggers mains switch and comprises fine motion type flash switch, the abnormity elastic lever, the deformed wire lever, the scalable stopping means, adjustment screw, the EF contact button, stopping means adjustment knobs and support and outer pot, wherein fine motion type flash switch and special-shaped elastic lever are rack-mount, and support is installed on the outer the bottom of a pan of rubber-like, and the scalable stopping means is installed on the outer pot sidewall, deformed wire lever and EF contact button and stopping means adjustment knobs are installed on the scalable stopping means, and adjustment screw is installed on the scalable stopping means.
The utility model has the advantages that not only can stepless temperature-regulating, pressure regulation, and when culinary art finishes, when can cut off the main circuit heating power supply automatically, connect relevant accessory power supply, its control stroke is little, the contact quick action, the reliability height, Installation and Debugging are convenient, and cost is low.
Further describe structure of the present utility model below in conjunction with accompanying drawing, wherein:
Fig. 1 is the structural representation that mechanical bistable state power control of the present utility model triggers mains switch;
Fig. 2 is the schematic diagram of the relevant active force of the special-shaped elastic lever among Fig. 1.
Triggering mains switch referring to the control of accompanying drawing machinery bistable state power is made up of fine motion type flash switch (3), special-shaped elastic lever (4), deformed wire lever (5), scalable stopping means (6), adjustment screw (7), EF contact button (11), stopping means adjustment knobs (12) and support (2) and outer pot (1).
Wherein fine motion type flash switch (3) and special-shaped elastic lever (4) are installed on the support (2), and support (2) is installed in rubber-like outer pot (1) at the end; Scalable stopping means (6) is installed on outer pot (1) sidewall, and deformed wire lever (5) and EF contact button (11) and stopping means adjustment knobs (12) can be installed on the scalable stopping means (6).
In use, when pressing EF contact button (11), touch deformed wire lever (5), stir the A ' point of special-shaped elastic lever (4) by deformed wire lever (5), the direction of A ' some power F1 (shown in Fig. 2 F1) is by the effect of fulcrum B, make the displacement of C point generation (as shown in Figure 2) power F2 direction of special-shaped elastic lever (4), cause moving contact F (as number in the figure 10) and fixed contact E (as number in the figure 8) to connect, reach the purpose of connection " main circuit ".As pressing EF contact button (11) repeatedly, then because fine motion type flash switch (3) has bistable memory effect and can not disconnect.
Produce the elastic displacement of vertical downward direction when outer pot, cause support (2) also to produce vertically downward displacement, when displacement reaches a set point, be installed in the adjustment screw (7) on the scalable stopping means (6), withstand the A point of special-shaped elastic lever, the effect of ordering by fulcrum B, make the C point generation rightabout power of F2 arrow as shown in Figure 2 on the special-shaped elastic lever (4), to cut off E, two contacts of F, promptly cut off nutrition pot heating board main circuit power, connect moving contact F simultaneously, auxiliary contact D (label 9 as shown in FIG.) promptly connects by " auxiliary contact ", the signal of telecommunication that the output culinary art finishes.When the culinary art of nutrition pot finishes, stop heating, after cooling a period of time, when the pressure in the pot reduces to zero, the elasticity maximum displacement vertically downward in the outer pot the bottom of a pan at the EF break of contact, stop to heat, in the process of cooling gradually, support (2) also produces vertically upward displacement with the outer pot the bottom of a pan, up to getting back to initial condition, because of fine motion type flash switch (3) has memory effect, and can not connect the EF contact once more yet, cause the main circuit energising.If connect the EF contact, must press EF contact button (11) once more, repeat process as mentioned above, just can reach the purpose of connecting main circuit.
The utility model is applied on the series of patents products such as " multifunctional self-regulating energy-saving norishing pots ", makes " multifunctional self-regulating energy-saving norishing pot " reach hundred-percent commercialized degree.Not only can stepless temperature-regulating, pressure regulation but also when culinary art finishes, when can cut off the main circuit heating power supply automatically, connect relevant accessory power supply, make " multifunctional self-regulating energy-saving norishing pot " reach supermatic requirement.
The utility model also can be applicable in the range of application of some precision optical machinery controls and the control of accurate displacement amount.
