Definitions
- the present invention relates to a control apparatus for an electric appliance requiring a programmed connection and disconnection.
- Said apparatus comprises two timing devices, a switch means, used to electrically connect the electric appliance to an electric supply in dependence on the conditions of the two timing devices, in which the first timing device (or long time period device) comprises a dial and a knob driven from the dial by means of friction and an operating means which is actuated at the end of the timing period set on the first timing device, while the second timing device (or short time period device) has a dial and comprises an actuating means for the switch means, a clamping block being operatively connected between said first timing device and said second timing device to clamp the second timing device so that, by manually rotating the knob to a selected position, said first timing device is set and at the same time the second timing device is prevented from starting its counting, while, by rotating the dial of the second timing device to a selected position, the duration of the period during which the electric appliance will be connected to the electric supply is set.
- Patent specification DE-C-549 279 describes an apparatus according to which it is possible to program the delayed electric appliance connection on the basis of the hours and/or minutes which have to elapse before the selected moment (setting time).
- Said device has many disadvantages, which are basically comprised in two groups:
- Another object is to provide a construction of reduced dimensions, which can be installed with a few modifications on any electric appliance.
- the long time timing mechanism 9 is continuously operating: its output shaft in the embodiment shown makes one revolution every 12 hours.
- Its central shaft 9a (Fig. 5) has integrally connected thereto a bushing 9b and a clutch 9c driving said dial 1.
- the latter has a groove 1 a for resetting the time in dial 1 in case of lack of supply to the motor, and to this end the above mentioned clutch 9c is provided.
- the knob 2 having a mark 2a is connected on said dial 1 by means of a clutch 2b.
- This knob 2 also has a profiled notch 2c (Fig. 3), which engages the clamping lever 8 when the mechanism is at rest condition. Under this condition, said lever with its projection 8a leaves the switch 6 at free condition, which switch remains closed and at the same time the lever 8 does not contact the dial 4 with its clamping block 8b.
- the short time timing mechanism 10 is actually a minute indicator and is stationary at rest condition.
- This mechanism carries keyed rigidly on the shaft 10a (Fig. 5) the dial 4, the latter having a cam profiled portion 4a (Fig. 3) and a "manual" mark (Fig. 1 and 2), at which the dial 4 remains clamped in not shown known manner at a position in which the associated switch 7 connects the electric appliance 11. Under rest condition, said cam portion 4a acts upon said switch 7 maintaining it at open condition.
- the switches 6 and 7 are at open and closed positions, respectively, as shown in the diagrams of Figs. 6c and 6d, since the notch 2c has moved the initial position displacing the lever 8 which with its projection 8a acts on switch 6 and with its block 8b clamps the knob 4, preventing the short time mechanism from operating; at the same time, the cam profiled portion 4a is displaced and accordingly the switch 7 is closed.
- Fig. 6h shows the rest condition.
- Fig. 6i shows the electric appliance connection and disconnection for long times without any programming of cycle start. In this case, one only acts on knob 2, maintaining the short time timing mechanism stationary.
- a further performance is provided by the device positioning the dial 4 with the "manula" mark at the fixed reference pointer 5. Under this condition, the mechanism 10 is prevented from moving due to an inner stop and accordingly is retained at the indicated position until it is manually reset to zero or at a time ranging between 1 and 120 minutes.
- the above described condition contemplates the same behaviour of the switch as those described in the previously examined diagrams and allows a continuous operation of the electric appliance in the interval between two manual operations when acting only on the dial 4, and a programmed operation of the beginning if the knob 2 is set.
- This invention comprises all of those variants that may be apparent to those skilled in the art. Particularly, by reversing the conditions of the switches, instead of controlling periods of current supply periods of current supply suspension can be controlled. Moreover, the position of the dials and fixed pointers can be reversed.
