Abstract

PURPOSE:To provide a timer with an improved using convenience, being adapted to utilize a ''good-night'' circuit as an original purpose timer and also as a timer operable during the actuation of ''good-morning'' timer. CONSTITUTION:Upon the knob 2a of ''good-morning'' timer being turned ON, a change-over switch 24 has its contacts 25-30 connected for generating a voltage at a point (g). At this moment, the potential of point Q is changed from low to high level and simultaneously making high level in the potential of IC 55's start terminal 3, and output terminals 6-2, by turning ON the ''good-night'' timer switch 13. Thus, a transistor 53 is turned ON via a resistor 56 with the simultaneous energization of transistor 54. That is, turning ON of ''good-night'' timer switch 13 makes the IC 55 for timer an ON condition. Subsequently, the transistors 53 and 28 are retained ON for a preset timed duration on a resistor 58 and a condenser 60, actuating a relay 64 to close a contact 65 which is normally opened. The power is thus supplied to a load 11a and an operation lamp 5a, lighting ON an operation lamp 5a.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF APPLICATION IN J-STAR INDUSTRIAL APPLICATION The present invention relates to a temperature mode timer used in oil fan heaters and the like.

Conventional configurations and their problems In recent years, in order to improve the usability of heaters and the like, heaters with associated functions such as timers have come into use.

FIG. 1 shows the operation surface of the conventional timer for kerosene heaters. In Fig. 1, the operation panel 1 is equipped with a timer knob 2, a scale 3 for setting a good morning timer, a knob 14 for setting the temperature d/pa, and furthermore, the timer knob 1 2 is set to the "operation" position. An operation lamp 6 is arranged to indicate that the load is energized when the timer is set to ``operation'', and a timer lamp 6 is arranged to indicate that the timer is set when the timer switch 2 is turned clockwise from the ``operation'' position. ing.

FIG. 2 is a control circuit diagram of the timer. In FIG. 2, one end of the power supply 7 is connected to the contact 9 of the timer 8, and the other end is connected to the timer coil 10, the load 11, the operation lamp 5, and one end of the timer lamp 6, respectively.
The operation lamp 5 is connected to the load 11 and the timer lamp 6 is connected to the timer coil 10 in parallel. It's ox, contact 12? L
, 12b are timer coils 10., 12b, respectively. It is connected to the load 11.

Note that FIG. 2 shows the "off" state. It is assumed that all circuits for temperature adjustment are included in the load 11.

The operation of the control circuit configured as described above will be explained below.

First, when timer knob 2 is set to the "run" position, contact 9
is connected to the contact 12b, voltage is applied to the load 11 and the operating lamp 5, the load 11 is continuously operated, and the operating lamp 5 is also lit. Next, for timer settings, set timer 1 and 2 to the scale,
j: When set to desired position among 13, contact 1 and contact 1
2& is connected and the timer operation starts and the timer rung 6 lights up. -4C and when the set time elapses, load 11 operates for a certain period of time, then automatically stops, and timer rung 6
The lights also go out.

However, such conventional timers for heaters such as oil and gas fan heaters have a mechanism that after a set time has elapsed, the heating operation continues for a certain period of time and then automatically stops. Tonto is a sleep timer like this, so if you want to keep the heating on for a little longer, for example when you go to bed on a cold night or when you go to bed immediately after returning home, you need to set a sleep timer. Ta. However, in the past, such settings were not possible, or if you set the Oyacho timer, it would be the same as the Obayo timer. It had the disadvantage of being bad. Also,
When two timer functions are provided, two identical timers are required, which increases the cost.

- connected to the collector-emitter IC point of transistor 28; The normally open contact 65 of the relay 64 is the point a and the 9 load 112L.
The load 11aVC is connected to the operating lamp 5a in parallel.

The operation of the control circuit configured as described above will be explained below.

1. Turn off the operation switch 16 in Figures 3 and 4.
Then, since no DC power is generated between points b and c,
The timer does not operate even if other switches are turned on.

Next, set the Goodbye timer knob 2a to "continuous" A, contacts 26-26 of the changeover switch 24 are connected, so the transistor 28 is always connected by the relay 64 (1) i44 point 65 is closed and the load 11a and operation lamp 52L are connected. A voltage is applied. The timer does not set 4 on this platform.

77 When the VC round bye timer switch 2a is turned on, the contacts 26-30 of the changeover switch 24 are connected, and the q
A voltage is generated at the point. At this time, when the sleep timer switch 13 is turned on, the potential at point Q changes from low to high, and IC55
The start terminal 3 and output terminal 6-2 of 0 also become high. Therefore, the transistor 53 is turned on through the resistor 66, and the transistor 64 is also turned on. That is, when the sleep timer switch 13 is turned on, the xc5 colors for the timer are turned on.
state. From this point onwards, during the time determined by the resistor 58 and capacitor 60, the l transistor 53 is set to 0N9fi.
Then, the l transistor 28 is also turned on, and the relay 6
4, the normally open contact 65 closes, power is supplied to the load 112L and the operating lamp 52L, and the operating lamp 5 & +Ii lights up.

From point Q, the timer lamp 14 also lights up, confirming that the operation and timer settings are complete. After a certain period of time 111 has elapsed, the output terminal 6-2 of the circuit C55 becomes low, so the transistor 63 becomes OFF state,
The transistor 64 and the transistor 28 are also turned off. Therefore, the timer IC 55 is turned off, and power supply to the load 11a and the retardation lamp 6a is stopped.

When setting the timer for the next time, turn the timer knob 22L clockwise to set the desired time.

At this time, the contacts 25 and 30 of the change-over switch 24 are connected, so when the bye-bye timer switch 16 is turned on, the timer IC 32 is also turned on by the same operation as in the innite timer. The set time at this time is determined by the volume 23 and the capacitor 36. When the good morning timer circuit 22 is in the operating state,
The timer lamp 6a lights up and the transistor 38.
Since the transistor 41 is in an ON state, the transistor 43 is also in an ON state. 1, the transistor 50 is in a bad OFF state,
Therefore, it has no relation to the operation of the snack timer circuit 31 at all.

When the setting lI also reaches 1, 1 is output from the output terminal of engineering C32.
point ( becomes low and transistor 41 and transistor 3
8 is in the OFF state and the good morning timer circuit does not operate. However, since the capacitor 46 is photoelectrically connected through the diode 44 and the resistor 46, the transistor 50 is instantaneously turned on.

Therefore, the transistor clock 4 is turned ON, and the sleep timer 31 is turned ON again, and the load 11a and the lamp 5a (d) operate.In this case as well, the set time is the time determined by the resistor 68 and the capacitor 60VC. Generally, it takes about 1 hour.

- Also, if you turn on the good night timer switch 16 and the night timer switch 13, it will be a good night.

For example, it can be operated for one hour immediately after operation, and then operated for one hour after γ time. Furthermore, each timer can also be used independently.

In this way, the sleep timer is a circuit that can be used not only as the original sleep timer, but also according to the operating time of the goodnight timer, and can be used in various ways depending on the time and situation, making it easy to use. It is possible.

1. It's all made up of 5 electronic parts, so the price can be kept low, and the setup time can be determined easily.

Effects of the Invention Not only can the sleep timer circuit be used as the original sleep timer, but also the sleep timer function can be used during the sleep timer operation, which simplifies the configuration.

You can freely select and set the goodbye timer and sleep timer separately or together, making it easier to use.

Since it is entirely composed of electronic components, it is easy to set the time limit, etc.
