The time switch circuit 5 'in FIG. 2 is turned on by the timekeeping mechanism 7 including, for example, a synchronous motor, and the timekeeping mechanism 7. Includes a contact or switch 8 that is controlled off. The AC time switch circuit 5 ′ including the synchronous motor in the timekeeping mechanism 7 requires an AC power supply as a power supply for operating the timekeeping mechanism 7. Therefore, when this time switch circuit 5 'is used in place of the switch circuit 5 shown in FIG. 1, the time connected to the power supply line 3 is required. It is necessary to newly add a switch power supply line 9 for wiring. Therefore, in the conventional circuit shown in FIG. 2, the wiring work for arranging the timing switch circuit 5 ′ becomes complicated, and the The drawback was that the stall increased. Such a disadvantage is that the switch circuit 5 (Fig. 1) already mounted on a wall or the like is replaced with a time switch circuit 5 '(Fig. 2). In the case of a change, this is more noticeable.

In order to simplify the wiring work as described above, it is conceivable to use a timekeeping mechanism driven by a dry battery in the time switch circuit 5 '. However, if a battery-operated type of time switch circuit is used, replace the dry batteries used there with a new one at an appropriate time.

OiviPI,. WIPO According to the present invention, it is only necessary to wire the voltage extracting means and the contact or the switch means in relation to one of the two power supply lines for supplying the AC power, but it has been possible. This eliminates the need for extra wiring work, which is required in the wiring of a conventional AC timer device. Therefore, even if it is necessary to replace the already installed so-called one-sided manual switch with a time switch, it is easy to replace it. It is very useful, especially when the wiring is embedded in the wall.

Even if the load is switched off by the switch means and the current to the voltage extraction means is interrupted, the timer is activated by the output of the storage battery and continues to keep time. I can do it. Thus, according to a preferred embodiment of the present invention, only one switch or contact can be used to set the desired time at a pre-set time. AC power can be supplied to the load and the supply can be cut off.

, Instead, use a voltage drop instead of a transformer. As such a voltage drop means, a resistive element or a diode can be used. If such a voltage drop means is used, the size can be further reduced as compared with the case of a transformer. Furthermore, if the voltage drop means is constituted by a diode, heat generation is not so large as compared with the case where a resistive element is used, and therefore efficiency is high. If a diode is used, the diode's constant voltage characteristics (the voltage drop is almost constant regardless of the change in the current flowing through the diode) For this reason, it is not necessary to provide a separate constant-power E. In other words, even if the impedance of the load or the power supply voltage of the AC power supply fluctuates, the operation of the timekeeping mechanism is maintained. Since the voltage drop means is substantially inserted in series with one of the two power supply lines, it is configured with a diode. In such cases, provide a bino-source path to allow the current to the load to be bypassed during the half-cycle of the AC power supply, when the diode is reverse-biased. Need to be opened. '

BEST MODE FOR CARRYING OUT THE INVENTION

A time switch circuit 15 is provided in association with one of the two power supply lines 14. The time switch circuit 15 is provided with voltage extracting means 16 for extracting a voltage from the power supply line 14 in accordance with the current flowing through the power supply line 14. In this embodiment, the voltage extracting means 16 uses a diode circuit in which four diodes are connected in series. This diode circuit or voltage extraction means 16 is used as a voltage drop means, and is therefore replaced by a resistor circuit instead of such a diode circuit. If such a resistive element is used, You can do it. Generally, it is known that a diode generates a constant forward voltage drop regardless of the current flowing therethrough. As in this embodiment, if four diodes connected in series are used as the voltage extraction means or the voltage drop means 16, one diode can be used. Assuming that the forward drop voltage is 0.6 V, for example, a voltage of about 2.4 V is taken out at both ends of the means 16. If such a diode circuit is used as the voltage extracting means, it is not necessary to use another constant voltage element because of the constant voltage characteristic peculiar to the diode.

The voltage extracted by the voltage extracting means 16 is rectified by the rectifying diode 18 and then smoothed by the smoothing capacitor 19. Then, the DC voltage is given to the timing mechanism 17 '. The clocking mechanism 17 is taken out by the voltage take-out means 16, and is not driven or energized by the rectifier hh, and is an arbitrary preset value. At a different time, the electrical connection between the AC power supply 11 and the load 12 is substantially conducted and cut off.o The time switch circuit 15 is composed of the timekeeping mechanism 17 and its It has a mechanism for switching the switches 1555 and 1556 (Fig. 3) included in the timer according to the timing.

Here, the time switch circuit 15 will be described in more detail with reference to FIG. The time switch circuit 15 is housed in a housing, for example, and is placed in front of the housing.

O PI _ A dial 151 is provided on the surface panel, and the diagonal 151 is rotated in the direction of arrow いて inside the housing, though not shown, inside the housing. It is supported. At a predetermined position on the front panel, an index 152 is provided for the dial 151. In connection with the antenna 151, further, time setters 1553a and 1553b are provided. These time setting elements 15 3 a and 15 3 b are provided so as to be free to slide along the periphery of the dial 15 1 without displacement. One of the time setters 15 3 a starts supply of AC power to the load 12 (FIG. 3) at the time indicated by the time setter 15 3 a, and the other This is to cut off the supply of AC power to the loads 12 at the times indicated. These time setting elements 15 3 a and 15 3 b are used to manually set the time setting number on the dial 15 1. It is rotated in the direction of arrow A integrally with the dial 15 1 by ') described later. When the setting switch 153a and the index 152 match in position with the rotation of the diode 151, the time switch circuit 15 applies a load to the load 12. Start the supply of AC power, and then supply the AC power to the load 12 when the time setter 15 3 b and the index 15 2 coincide with each other as time elapses. To shut off.

In the embodiment shown in FIG. 3, two switches 1555 and 1556 are provided in a manner different from the timing mechanism 17 and these switches are provided.

OMPI Switches 1 5 5 and 1 5 6 are normally open contacts, respectively.

Includes 155a and 156a and normally closed contacts 155b and 156b. In the case of this embodiment, if the on-time specifier 15 3 a and the index 15 2 coincide in position, the switches 15 55 and 15 6 are normally open contacts 15 5 Switch to a and 1556 a side, and if the OFF time setter 15 3 b and the index 15 2 match in position, the normally closed contacts 15 5 b and 15 6 Switch to b side. It is already well known about such switching of switches, so a detailed illustration and explanation of the mechanism are given here. Is omitted.

As shown in FIG. 4, a switching switch is provided on the front and rear of the housing of the time switch circuit 15.

15 4 are provided. This switching switch 154 is a switch that can be switched to the third position, and switches the positions of,, ON,, \, AU, and OFF. Have. By switching this switching switch 154 to the 0 N 〃 position, it becomes possible to supply AC power to the load 12 irrespective of the timing of the timing mechanism 17. Conversely, by setting the switching switch 154 to the OFF position, the supply of AC power to the load 12 can be cut off irrespective of the timing mechanism 17. In the embodiment shown in FIG. 3, when the switching switch 15 54 is set to the ON position, the switches 15 55 and 15 56 are normally open contacts 15 55 a and 1 Switch to the 5 or 6a side, and turn to the OFF "position

ΟΜΡΙ Then, it switches to the normally closed contacts 1 55 b and 1 56 b. Therefore, though not shown in detail, the switches 1555 and 1556 are provided on the front. Interlocks with the switching switch 154 provided on the cell. By the way, another switch for turning on or off the supply of AC power at the ON or 0FF "position of this switching switch 1554 Switches 1555 and 1556 may be interchanged and switched as a matter of course. .

Again, as shown in Fig. 3, the voltage extracting means 16 is connected to the common contact of the switch 156, and the normally closed contact 156b of the switch 156 is current controlled. It is connected to the power supply line 14 via the current limiting resistor as the limiting means 20. That is, the voltage extracting means and the switch 156 constitute a series circuit, and this series circuit is inserted into the power supply line 14. To this series circuit, a series circuit of a diode constituting the bypass means 21 and a switch 1555 is connected in parallel. That is, the diode 21 is connected to the diode circuit 16 in an anti-parallel manner, and the node is connected to the common contact of the switch 1555. At the same time, it is connected to the normally open contact 156a of the switch 156. The normally open contact 1555a of the switch 1555 is connected to the power line 14 and the normally closed contact 1555b is opened.

Referring to FIG. 5, a preferred example of the timing mechanism 17 is shown.

Since the current time, that is, 15:00 is before the on-time, that is, before 18:00, switches 1555 and 1556 are normally closed contacts, respectively. It has been switched to the 1555b and 1556b sides. Therefore, the current path of the diode 21 for the no-pass is cut off. On the other hand, AC power supply 11, power supply line 13, load 12, power supply line 14, current limiting means 20, switch 17 · 6, voltage extraction means 16 and series connection of power supply line 14 A closed circuit is formed. Now consider the load 12 as a load like an incandescent lamp. The resistance value of the current limiting means 20 is appropriately selected so that a minute current flows in the above-described series circuit. The small current is generally selected so that the load 12 does not substantially operate and an effective voltage drop occurs in the diode. For example, if the load 12 is a 100 W incandescent lamp, and if the AC power supply 11 is 100 V, the value of the current limiting resistor 20 is 18 K, for example. Choose for £. Then, a current of about 5.6 mΑ flows through the above-mentioned series circuit. At such a small current (5.6 mA),

OP IP The incandescent lamp of 100 "W as the load 12 hardly emits light. On the other hand, the minute current flows through the diode circuit as the voltage extracting means 16 Then, since the current value exceeds the forward threshold value of the diode, a voltage drop of about 2.4 V is generated. The extracted voltage is rectified by a rectifier diode 18 and a timekeeping mechanism 17 by a smoothing capacitor 19, that is, a terminal 17 2 (5th Thus, in this embodiment, even if the AC power to the load 12 is substantially cut off, this is not the case. A small amount of current is passed to the extent that the load 1 2 does not substantially operate, and a voltage for the timekeeping mechanism 17 is generated by the voltage extracting means 16. A predetermined voltage is applied to the terminal 17 2. When given, et al. Are, integrated

Therefore, the current from the AC power supply 11 to the load 12 is connected to the series circuit of the voltage extraction means 16 and the switch 156 or the diode for the vino or switch. Flows through C2 1. Since the polarity of the diode 21 and the voltage extracting means 16 is opposite, alternating positive and negative currents are supplied to the load Γ2. In this way, the load 12 substantially starts operating at the set ON time, that is, 18 o'clock. When the switch 1556 is switched to the normally open contact 1556a side, the current limiting means 20 is removed from the series circuit, so that there is no voltage drop means. . The current flowing through the pressure extraction means 16 becomes larger than the small current. However, since the voltage extracting means 16 is composed of a series circuit of diodes, the voltage at both ends is extremely small due to the constant voltage action of the diode. When current is flowing, that is, the load 12 is maintained at about 2.4 V, which is substantially the same as when the load 12 is not operating. Then, in response to the large current flowing through the load 12, a voltage is extracted from the voltage extracting means 16, whereby the timing mechanism 17 is deenergized and driven. Continue to be.

In response to the continued biasing or driving of the timing mechanism 17, the motor 17 4 continues to rotate and the dial 15 1 continues to rotate. Therefore, the offset time setter _{15 3} b set to 24 of the antenna 15 1 is set to the index 15 2

In the above description, the load 12 is described as a case where the load such as an incandescent lamp, that is, the terminal 12a and the terminal 12b are always conducted in a DC manner. did. However, the load driven by this timer device may be a fluorescent lamp as shown in FIG. The Yinguang lamp 1 2 1 has a filament at both ends, and between the filaments is almost electrically blocked until discharge starts. You. A choke coil 122 is interposed between one of the filaments and the terminal 12a. One end of the other filament is connected to terminal 12b. The other ends of both filaments are connected via a global ramp 123. A noise prevention capacitor 124 is connected in parallel with the ground lamp 123. This noise suppression capacitor 124 is for preventing the radio wave interference that occurs while the Yinguang lamp 122 is lit, and is typically used. Is used for 0.06 F or 0.5 F force.

Conducted through a high impedance. At this time, the current limiting means 20 is set to an appropriate value of resistance or impedance in consideration of such an impedance. Therefore, the timer device of the present invention is not an incandescent lamp but an AC conducting device such as a fluorescent lamp. Any load that can be controlled can be controlled. Thus, similarly, for a cold cathode discharge lamp such as a mercury lamp, the distance between the discharge electrodes is substantially reduced via the impedance. Since the current is conducted in an alternating manner, the on-time and the off-time can be controlled by the timer device of the present invention in the same manner. '

FIG. 7 is a circuit diagram showing another embodiment of the present invention. This embodiment incorporates a storage battery 22, such as a nickel-cadmium battery, within a timer 15, depending on which one it is. The third embodiment differs from the embodiment of FIG. 3 in that the switch 1555 'is turned on or off to control the supply and cutoff of AC power to the load 12. You. That is, in this embodiment, the voltage extracting means 16 and the switch 1555 'are connected in series with the power supply line 14. The voltage extracting means 16 includes the diode circuit power as in the previous embodiment. In this diode circuit, a diode for bypass is used in an inversely parallel system | J mode. -Node 21 is connected. Current limiting means 20 ′ is interposed between the output terminal of the voltage extracting means 16 and the rectifier diode 18. The DC voltage smoothed by the smoothing capacitor 19 charges the storage battery 22. Therefore, the timer 17 is driven by the output of the storage battery 22 without being energized. In this embodiment, when the on-time setting element 15 3 a shown in FIG. 4 matches the position of the index 15 2, no contact or switch 15 5 ′ is set. This switch is turned off when the off time setter 15 3 b matches the position of the index 15 2. As for the timing mechanism 17, as in the previous embodiment, a crystal oscillation type as shown in FIG. 5 can be used, and other balances can be used. Driven ones can be used.

Next, referring to FIGS. 4 and 5 together with FIG. 7, the operation or operation of this embodiment will be described. The operation for setting the on-time and off-time by the time setting elements 153a and 153 shown in FIG. 4 is the same as in the previous embodiment. The current time is 15 o'clock. At this time, the switch 1555 'is off. Therefore, no current flows through the path of the power supply line 14, that is, the voltage extracting means 16. For this reason, when the switch 15 5 ′ is off, there is no output from the voltage extracting means 16. From the low power s ', in this embodiment, the switch 1555' is extracted from the voltage extraction stage 16 during the ON time period.

O PI IPO Battery 22 is charged. For this reason, at least when the switch 15 5 ′ is off, the timing mechanism 17 is not energized or driven by the output from the storage battery 22. It is done. Therefore, even during the off-period of the switch 1555 ', the motor 174 (Fig. 5) continues to be energized, and as a result, is continuously turned on. Timekeeping is achieved.

The dial 15 1 (Fig. 4) rotates in response to the rotation of the motor 17 4, and when the ON time comes, the switch 17 5 'is turned on. . Therefore: AC power supply 11, power supply line 13, load 12, power supply line 14, switch 15 5 ′, voltage extraction means 16 [or parallel connection to it A closed circuit in series is formed by the bypass diode that is provided — '21 :) and the power supply line 14. Therefore, the load 12 is driven by the AC power supply 11, and at the same time, a current flows through the voltage extracting means 16, and a voltage is extracted therefrom. The output of the voltage extracting means 16 is given to the rectifier diode 18 via the current limiting resistor 20 '. The current limiting resistor 20 'effectively prevents excessive current from flowing through the rectifier diode. The DC voltage rectified by the rectifier diode 18 and smoothed by the smoothing capacitor 19 is charged in the storage battery 22. Then, as the time elapses, the off time is reached, the switch 1555 'is turned off, and the AC power to the load 12 is cut off. Therefore, the output of the voltage extracting means 16 also disappears, but the timekeeping mechanism i ₇ is, as described above,

Ο ΡΣ WIPO QL It is not energized or driven by the output of battery 22.

FIG. 8 is a circuit diagram showing still another embodiment of the present invention. This embodiment is almost the same as the embodiment in FIG. 7, except for the following points. That is, in this embodiment, the voltage extracting means 16 ′ is configured by using a transformer instead of a diode circuit. The primary winding of this transformer is connected in series to the power supply line 14 together with the switch 1555 '. The output from the secondary winding of the transformer is rectified by the rectifier diode 18 and smoothed by the smoothing capacitor 19. In this embodiment, since a transformer is used as the voltage extracting means 16 ′, the voltage changes according to the change in the current flowing through the load 12. In order to suppress such voltage fluctuations, a constant voltage diode 23 is used. Then, the DC voltage, which has been made constant by the constant voltage diode 23, is charged into the storage battery 22. 7, the current limiting means 20 ′ is interposed between the rectifier diode 18 [smoothing capacitor 19:) and the constant voltage diode 23. According to the present invention, as in this embodiment, not voltage dropping means but voltage inducing means such as a transformer can be used as voltage extracting means. Note that, in this embodiment, the output voltage of the rectifier is made to be substantially the same as that of the previous embodiment.

In the above-described embodiment, the current limiting means 20 or 20 'uses a current limiting resistor as a current limiting means. Depending on whether the current to be supplied is direct current or alternating current, other impedance means can be used as appropriate.
