Abstract

PURPOSE:To prevent the time switch from not being returned to program operation forgetfully by providing a period setting means which turns on a load temporarily. CONSTITUTION:The period wherein the load 7 is turned on is set by the period setting means 1 and when a setting detecting means 3 detects that, a timer means starts clocking the set period and an output control means 5 turns on the load with the output of the means 4 at this time. Then while the means 4 is in the clocking operation, the load 7 is held on and the output of a program control means 6 is ignored. Then the means 5 turns off the load 7 the set period later and the operation which ignores the program is released, the load 7 is controlled thereafter according to a program. Further, the means 5 controls the operation of the load 7 according to the output of the means 6 unless the period wherein the load 7 is turned on is set in the means 1. Thus, the load 7 can be turned on temporarily by the single-time operation for setting the on period of the load 7 by the means 1, so the operation is simplified and an automatic return to program operation is made, so the switch is never held reset forgetfully.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a time switch incorporating a microcomputer and controlling the operation of a load according to a program.

[Prior Art] Some time switches have a built-in microcomputer and control the operation of a load according to a program. By the way, in this time switch, for example, when the program is ignored and the load is kept on for a certain period of time, that is, when the load is temporarily turned on, the following is done.

(1) Turn on the time switch using the manual switch.

(2) Turn on with a switch connected in parallel to the time switch output.

(3)-Enter a temporal program and cancel the program after the operation is completed.

Further, as this type of time switch, there is one in which a program can be set for each day of the week, and the operation of the load is controlled according to a weekly program made up of these programs. Conventionally, when using this time switch to suspend load operation for a period of several days, the following method was used.

(1) Turn off the main breaker.

(2) Turn off the time switch using the manual switch.

(3) Turn off with a switch connected in series to the output of the time switch.

[Problem to be Solved by the Invention 1] However, when temporarily turning on the load as described above, there is a problem in that two operations are required before and after turning on the load, making the operation cumbersome.

For example, when the load is turned on as shown by the diagonal lines in FIG. 32(b) using the manual switch method described in (1) above, the start point of the period in which the load is turned on is 1. The manual switch must be turned on at t2, and must be turned off at the end of the period t2. Moreover,
If you forget to turn off the manual switch, that is, to return to programmed operation, problems may occur during work. Note that FIG. 32 (, ) shows the program set in the time switch.

By the way, the load is forcibly turned on by an external signal.

The time switch to turn it off is from Utility Model 59-115386.
Although this type of time switch has been proposed in the above-mentioned publications, the same problems as those of the above-mentioned manual switch occur.

In addition, there is a time switch that can set a program for each day of the week, and that inputs a -temporal program and cancels the program after the operation is completed.
- Although it is provided in Publication No. 278784, etc., the same problem as with manual switches occurs when the load is forcibly turned on and off using this program, and in this case, it is necessary to rewrite the program. Considerable effort is required to obtain a temporary load on state.

In addition, in a time switch that controls load operation according to a weekly program, when using the method (1) using a breaker to turn off the load for several days, turn off the load the day before a holiday and Turn on the load at the start of work. For example, if the program shown in Figure 33 (a) is set up, there may be cases where it is necessary to turn on the load before a holiday, as shown by the broken line on the left side of Figure 33 (b), or after a holiday. When it is necessary to turn on the load as shown by the broken line on the right side of the figure, the output shown in the shaded area cannot be obtained by operating the breaker during normal working hours as shown in (a) of the figure.

Note that T' in FIG. 33(a) indicates a holiday period. Therefore, when turning on the load in the shaded area, it was necessary to wait until the start of the holiday to turn off the load and then turn off the breaker, or to turn on the breaker early after the holiday. Moreover, with the above method using a breaker, the power to the time switch itself is turned off before holidays, so depending on the length of the holiday period, the backup time of the time switch's memory may be exceeded, and the program must be input again at the start of work. There were times when situations occurred where I had to do something.

The specific invention has been made in view of the above-mentioned problems, and its purpose is to provide a time switch that is easy to operate to temporarily turn on a load and that does not cause the user to forget to return to programmed operation. It's about doing.

The related invention also provides a time switch that can automatically turn off the load when it is necessary to turn on the load over holidays, and turn on the load before starting work after the holiday. This is the purpose.

[Means for Solving the Problem] In order to achieve the above object, the specified invention provides a program control means for operating a load according to a preset program, a period setting means for setting a period for turning on the load, and a program control means for operating a load according to a preset program; a setting detection means for detecting that the setting has been made by the period setting means; a timer means for timing the setting period set by the period setting means; and a timer means for keeping the load in an on state during the timer operation period of the timer means. The apparatus also includes output control means for controlling the operation of the load according to the output of the program control means after the set period has elapsed.

In addition, in order to make the time switch that controls the operation of the load according to a weekly program easy to operate and prevent forgetting to turn it off, program control that operates the load according to a weekly program consisting of a preset program for each day of the week is required. means, a period setting means for setting a period of several days for keeping the load in an on state in units of days, a setting detection means for detecting that a setting has been made by the period setting means, and a period setting means for a period determining means for determining the set period; an on-period setting means for setting the on-period according to the output of the period determining means and the program control means; The on-period setting means controls the operation of the load and also controls the operation of the load according to the output of the program control means after the set period has elapsed. When the output of the program control means turns on the load at α, the start point of the set period is set as the start point of the on period for turning on the load, and the start date of the set period is set. If the output of the program control means is in a state where the load is turned off at this point, the time when the program control means turns on the load for the first time within the set period is the start point of the on period, and the last day of the set period ends. If the output of the program control means is in a state where the load is turned on at the time, the end of the set period is the end of the on period, and the output of the program control means is set to turn on the load at the end of the last day of the set period. When the load is turned off, the on period may be set by setting the output point of the program control means to turn off the final load on the last day of the set period as α at the end of the off period.

In addition, when setting the load to be turned on for several days as described above, if the reservation setting is made several days in advance, the above period setting means can be used to set the starting day of the period for which the load is to be kept on for several days. can be set, and a start day of the week determination means is provided for determining the start day of the week set by the period setting means.Furthermore, in the related invention, in order to achieve the above object, a program is set in advance for each day of the week. a program control means for operating the load according to a weekly program consisting of; a period setting means for setting a period of several days during which the load is kept in an off state; and a period setting means for detecting that settings have been made by the period setting means. a period determining means for determining the set period set by the period setting means; an off period setting means for setting the off period according to the output of the period determining means and the program control means; and output control means for controlling the operation of the load according to the output of the off-period setting means, and after the lapse of the off-period, controlling the operation of the load according to the output of the program control means, the off-period setting means Now, if the output of the program control means is in a state where the load is turned off when the start date of the set period arrives, the set period is set as the off period for turning off the load, and the start date of the set period is set as the off period. If the output of the program control means immediately turns on the load when It is set in the off period.

In addition, in the related invention, when the setting for turning off the load for several days can be reserved several days in advance, the start day of the period for keeping the load in the off state for several days can be set using the above-mentioned period setting means. It is only necessary to make the period setting possible and to provide a start day of the week determination means for determining the start day of the week set by the period setting means.

Furthermore, in consideration of the case where it is necessary to temporarily turn on the operation of the load in the related invention, a manual switch may be provided to manually turn on and off the operation of the load.

In this case, there is a risk of forgetting to turn off the switch, so use the manual switch mentioned above to turn off the load when the output of the program control means reaches the state where the load is turned off for the first time after the operation of 1 within the off period. It's good to do this.

[Operation 1] By configuring the specified invention as described above, when the period for turning on the load is set by the period setting means, after the set period elapses, the state is automatically returned to the control state by the program control means, The load can be turned on temporarily with only one setting operation, making the operation simple and preventing forgetting to return to program operation.

Furthermore, by configuring the related invention as described above, when the off-period setting means needs to turn on the load over a holiday, the off-period setting means can simply set a period of several days during which the load is turned off. The off period is set based on the start date of the set deadline, so that if it is necessary to turn on the load over a holiday, the off period is set, and the off period setting means is set during the on period. By setting , it is possible to automatically turn on the load before starting work after a holiday.

[Example 11 An embodiment of the specific invention is shown in FIGS. 1 to 4.

This embodiment is a time switch in which a program control means 6 controls the operation of a load 7 according to a preset program, and when a period setting means 1 sets a period for turning on the load 7, the load 7 can be turned on temporarily. That's how it is. In order to turn on the load 7 during the period set by the period setting means 1, a setting detection means 3 for detecting that the period setting means 1 has made a setting;
A timer means 4 keeps the load 7 on during the timer operation period of the timer means 4, and operates the load 7 according to the output of the program control means 6 after the set period elapses. and output control means 5 for controlling. It should be noted that each of the means 3 to 5 and the program control means 6 are configured by software in the microcomputer 2.

The operation of temporarily turning on the load 7 will be described below. Note that FIG. 2 is a 70-chart of this operation. First, the period setting means 1 sets a period during which the load 7 is turned on.

When the setting detection means 3 detects that the period has been set, the timer means 4 starts measuring the set period, and the output control means 5 turns on the load 7 based on the output of the timer means 4 at this time. do. During the subsequent period (setting period T) during which the timer means 4 is performing the time counting operation, the load 7 is maintained in the on state as shown in FIG. 3(b).

That is, during this set period T, the output control means 5 ignores the output of the program control means 6. In other words, the off program for turning off the load 7 in the program shown in FIG. 3 (&) is ignored. Then, when the set period T has elapsed, the output control means 5 turns off the load 7, and thereafter the operation of ignoring the program of the output control means 5 is canceled. Therefore, from now on, the operation of the load 7 is controlled according to the program. Note that unless the period for turning on the load 7 is set by the period setting means 1, the output control means 5
controls the operation of the load 7 according to the output of the program control means 6.

By the way, as shown in FIG. 4, if there is a start point and an end point of the set period T during the period when the load 7 is on according to the program, as shown in FIG. The state where load 7 is turned on before T continues,
When the set time opening T has elapsed, the load 7 is turned off. In this case, the output of the program control means 6 that turns on the load 7 at the time of termination is ignored, and the program operation returns thereafter.

In this way, according to this embodiment, the load 7 can be temporarily turned on with a single operation of setting the period for turning on the load 7 using the period setting means 1, which simplifies the operation. There are advantages. Moreover, since the program operation is automatically returned to, there is no need to forget to release the program, unlike when using a manipulative switch.

[Embodiment 21 Figures 5 to 8 show embodiments of the pond of the specific invention. This embodiment is a time switch in which a program control means 6 controls the operation of a load 7 according to a weekly program consisting of a program preset for each day of the week.
The period T', which lasts several days, during which the load 7 is kept in the on state at 100°C, is set in days. In this embodiment, in order to turn on the load 7 during the set period T° set by the period setting means 1', a period determining means 4° is provided for determining the set period T' set by the period setting means 1'. A period determination means El is provided at the output of the setting detection means 3.
4' and 1. On-period setting means 8 is provided for setting the on-period based on the output of the program control means 6. Note that, if the output of the program control means 6 is in a state to turn on the load 7 at the start date of the set period T', the on-period setting means 8 sets the load 7 to the starting point of the set period T'. 7 is the start point of the on period for turning on, and if the output of the program control means 6 is in a state to turn off the load 7 at the start date of the set period T', then within the set period T' The point in time when the program control means 6 turns on the load 7 for the first time is the start point of the on period, and the point in time when the last day of the set period T' ends, the program control means 6 turns on the load 7.
When the output of the load 7 is turned on, the end point of the set period T° is set as the end of the on period, and at the end of the last day of the set period T, the program control means 6 is turned on. When the output is in a state where the load 7 is turned off, the on-period is set with the output point of the program control means 6 that turns off the load 7 on the last day of the set period T'' as the end point of the on-period. . Furthermore, the output control means 5
controls the operation of the load 7 according to the output of the on-period setting means 8 during the set period T'', and controls the operation of the load 7 according to the output of the program control means 6 after the elapse of the set period T''.
control the behavior of It should be noted that each of the above-mentioned means 4' and 8 is constituted by software in the microcomputer 2.

The operation of this embodiment will be described below with reference to chart 70 in FIG. In this embodiment, the period is set the day before the day when the load 7 is turned on. In the time switch of this embodiment, the setting detecting means 3 detects whether or not the period has been set by the period setting means 1. If the period has been set, the period determining means 4 determines the set period T°. do.

Then, from the time when 24:00 (midnight) has passed, load 7
enters a period in which it is turned on. However, in this embodiment, the load 7 is not turned on throughout the darkness of the set period T', but the load 7 is turned on as follows. That is, at 24:00, the on-period setting means 8 determines whether the output of the program control means 6 is in a state where the load 7 is turned on. If it is currently turned on, the start of the set period T' is the start of the on period in which the load 7 is turned on, and conversely, at 24:00, the output of the program control means 6 is turned on. 7 is in a state where the load 7 is turned off, the time when the program control means 6 first turns on the load 7 within the set period T' is the start time of the on period. Also,
In this on-period setting means 8, even at the end of the final day of the setting period T°, the output of the program control means 6 remains unchanged at the load 7.
If it is in the on state, the end of the setting period T° is set as the end of the on period, and if it is in the off state, the setting When the program control means 6 outputs the final turn off of the load 7 on the last day of the period T°, let α be the end point of the on period. For example, as shown in FIG. 7, if the output of the program control means 6 is not in a state to turn on the load 7 at the time of 24 o'clock, the output state of the program control element Pi6 within the set period T° The time when the load 7 is turned on for the first time is defined as the start of the on-period. As shown in FIG. 7, if the output of the program control means 6 is not in a state where the load 7 is turned on at the end of the last day of the set period T', then the final day of the set period T' ends. The output point of the program controller Pi6 that turns off the load 7 is defined as the end point of the on period. Then, by ignoring the off program of the program control means 6 during the on period, the dark load 7 during the on period is maintained in the on state. Note that when the set period T' has elapsed, the program control means 6 automatically returns to the program operation by canceling the operation of ignoring the off program.

By the way, if the load 7 is turned on by the program control means 6 at both the start and end of the set period T', as shown in FIG. 8(a), the on period is equal to the set period T'. In this case, the load 7 is turned on from the previous day until the next day after the set period T', as shown in FIG.

In this way, according to this embodiment, even in the time switch that controls the operation of the load 7 according to the weekly program, the load 7 can be turned on for several days, and the period setter #ffi 1 ' is set to the load 7. The load 7 can be turned on for several days with a single operation of setting the period for turning on the load.It is easy to operate, and since this setting state is automatically canceled, there is no need to forget to cancel it. Does not occur.

[Embodiment 31 Still another embodiment of the specific invention is shown in FIGS. 9 to 12. This embodiment controls the operation of the load 7 according to a weekly program, and is a time switch that can set the period during which the load 7 is turned on over several days.The time switch allows the setting to turn on the load 7 for several days to be reserved several days in advance. This is what I did.

To this end, in this embodiment, the period setting means 1'' is capable of setting the starting day of the week, and as shown in FIG. 9, a starting day of the week determining means 10 for determining the starting day of the week is provided.

In the case of this embodiment, the starting day of the week can be selected from any day of the week for the next week, excluding the current day.

The operation of this embodiment will be described below with reference to chart 70 in FIG. In the following explanation, as shown in FIG. 11, the load 7 is turned on for two days from Friday to Saturday, and the setting of this period and the starting day of the week are performed on Monday. In this embodiment as well, the setting detection means 3 detects whether or not the period setting means 1'' has set the period and the VrM start day of the week. The starting day of the week and the set period T° are stored.

Then, the day of the week determining means 11 determines whether or not the set starting day of the week has arrived after 24:00 (midnight). Then, when the start day of the week arrives, a period begins in which the load 7 is turned on. However, in the case of this embodiment as well, the set period T
Instead of turning on the load 7 all the time, the off-period setting means 8 sets an on-period and turns on the load 7 during this on-period, similarly to the second embodiment. FIGS. 11 and 12 are diagrams illustrating the operation of this embodiment.

In the case of this embodiment, the load 7 can be set to be turned on at most one week in advance, which is convenient for controlling equipment that is only touched by human hands once or a few times a week.

[Embodiment 4] An embodiment of the related invention is shown in FIGS. 13 to 21. In this embodiment, in a time switch in which the program controller Pi6 controls the operation of the load 7 according to a weekly program, the period setting means 1'' sets a period T'' over several days during which the load 7 is turned off, in units of days. Is it negative?
i! The period during which r7 is turned off is set the previous day. and,
In the case of this embodiment, an off-period setting means 9 is provided for setting an off-period based on the output of the period setting means 1'' and the program control means 6, and this off-period setting means 9 is controlled by software using the microcomputer 2. It is composed.

Note that if the output of the program control means 6 is in a state to turn off the load 7 at the start date of the set period T, the off period setting means 9 sets the set period T° to turn off the load 7. In addition, if the output of the program control means 6 is in a state to turn on the load 7 at α when the start date of the set period T' arrives, the first off period within the set period T' The off period is set from the time when the program control means 6 turns off the load 7 to the end of the last day of the set period T'.

Below is the operation of this example! In the time switch of this embodiment, which will be explained according to the chart 70 in Fig. 1514, the setting detecting means 3 detects whether or not the period is set by the period setting means 1°, and if the period is set, the period determining means 4 The set period T is determined by . Then, after 24 hours, a set period T' in which the load 7 is turned off begins.

However, in this embodiment, instead of keeping the load 7 in the off state throughout the set period T°, the load 7 is turned off as follows. That is, at 24:00, the off period setting means 9 determines whether the output of the program control means 6 is in a state to turn on the load 7 at α. Now, the 15th
When the load 7 is turned off as shown in the figure, the set period T' is directly set as the off period during which the load 7 is turned off. Then, by ignoring the on program of the program control means 6 during the off period, the load 7 is kept in the off state during the off period. Note that when the set period T' has elapsed, the program control means 6 automatically returns to the program operation by canceling the operation of ignoring the on-program.

By the way, as shown in FIG. 16(a), at 24:00, the off period setting means 9 starts the program control means 6.
When the output of is in a state to turn on the load 7, the off period is set from the time when the program control means 6 first turns off the load 7 within the set period T' to the end of the last day of the set period T'. do.

In other words, from the day before the set period T° to the start date, the load 7
When it is necessary to turn on the load 7, as shown in FIG. 16(b), the on state of the load 7 from the previous day continues even within the set period T', and from the time this operation ends, the load 7
This is an off period in which the power is turned off.

In this way, according to this embodiment, by setting the period during which the load 7 is to be turned on using the period setting means 1'', if it is necessary to turn on the load 7 over a holiday, the on state of the load 7 can be automatically changed. Load 7 can be continued using the breaker.
It is no longer necessary to wait for the load 7 to be turned off before a holiday before turning off the breaker, as in the case of turning off the breaker. In addition, since it automatically returns to the program operation after the set period T° has elapsed, the load 7 can be automatically turned on before the start of work after a holiday, eliminating the need to turn on the breaker early and saving time. It is possible to measure the human power ratio. Moreover, in this embodiment, since the load 7 is turned off automatically, the problem of exceeding the backup time of the time switch memory does not occur, unlike when the load 7 is turned off using a breaker.

Figures 17 and 1 show the appearance of the operating section of this time switch.
It is shown in Figure 8. Note that FIG. 17 shows a one-circuit output type, and FIG. 18 shows a two-circuit output type. The operation section of this time switch includes a mode switch SW for setting the period during which the load 7 is turned off, and a select switch S.
W2, an anoyast switch SW, and an enter switch SW are provided, and the period can be set using the LC provided in the operation section.
This is done while looking at the display on the display unit 11 such as D. In addition, switches SW1 to SW of this time switch are for time setting,
It is also used for program settings, program monitor operations, etc. In addition, there is also a darkness selector switch SW1 that shifts the "hour" by ±1 hour for daylight saving time.

The display section 11 of this time switch has a 24-hour hour display, a minute display, and a day display "1" that displays the day of the week numerically below the time display.
..., "7", time display rTIMEJ indicating that the time is displayed on the above time display, program display [PROG, J, to load 7] indicating that the program content is displayed on the above time display. On display "I" indicates that the output state is on, Off display "0" indicates that the output state to load 7 is off, automatic state when manual switch SW7 is operated automatically When daylight saving time is set with the darkness changeover switch SW5, a daylight saving time display "S" is performed to indicate that it is daylight saving time.

The operating section of the time switch is also provided with a display 12 that indicates the state of power supply to the time switch.

Hereinafter, the operation of setting the period during which the load 7 is turned off using this operation unit will be explained. The setting of this period is selected by pressing the mode switch SW. When this period setting mode is entered, the characters [HO] indicating the period setting mode as shown in FIG. " is displayed. Then, when the select switch S W 2 is pressed, "-1" blinks and changes to 2 as shown in FIG. 19(b).

After setting this period, press the enter switch SW4 to return to the time display state, which is the steady mode, as shown in FIG. . By the way, when changing the period, the period may be displayed by the same operation as described above, and this period may be changed using the adjustment switch SW. Note that when this change is made, if it is not the period to turn off the load 7, the period setting mode returns to the steady mode and the current time is displayed as shown in FIG. 19(d). If the setting is changed during the period in which the load 7 is turned off, when returning from the period setting mode to the time display mode, the load 7 is turned off as shown in Fig. 19(e). Off display [0

This is possible by controlling the operation of

In addition, the operation of the manual switch SW in this case is as follows.
This is a so-called permanent operation that continuously keeps the operating state of the load 7 constant regardless of the program.

Then, when the set period comes, the load 7 is controlled to be turned off. However, as mentioned above, if there is a program that turns on the load 7 between the set period and the previous day, the load 7 is turned off by the program'. The load 7 remains on until the set period is reached, and in this case, as shown in FIG. 19(g), the on display [J blinks (o) to indicate that the set period has come.

The terminal board 14a of the connection terminal 14 is directly connected to the printed circuit board 22, and a lid 21a that can be opened freely is attached to the connection terminal 14 portion of the cover 21 as shown by the broken line in FIG. 28(a). ing.

As shown in FIG. 26, the operation section of this time switch is provided with a mode switch SW, a select switch 5WI2, and a set switch SW, which are used to set the period during which the load 7 is turned off. This is done by looking at the display on the display unit 13. Note that this time switch also uses switch SW.
, ~SW, are used for operations such as time setting, program setting, and program monitor, and are also used for setting summer time. This time switch also includes a call switch SW1 that displays the contents of the program on the display unit 13 in order to monitor the program, and a manual switch SW1 that is operated when turning on and off the load 7 by manual operation. It is provided with an output state changeover switch SW for switching the signal for controlling the load 7 between a timer output and a pulse output. Note that the timer output is the output when setting the period mentioned above, and the pulse output is the output that turns off the output in a pulse-like manner.When setting the period for turning off the load, the output state changeover switch SW is used as the timer output. Switch it to the side. Here, settings for setting the output state to pulse output are also made using switches SW, . . . -SW, .

This time switch display WS13 has a 24-hour hour display, a minute display, a second display, and a day display "month" that displays the day of the week numerically below the time display.・, "Day J, time call display "Time call" indicating that the time display is displaying the time, program monitor display "Program monitor" indicating that the time display is displaying program content, to load 7 The on display is "ON" indicating that the output status is on, the off display is "off" indicating that the output status to load 7 is off, and when the manual switch S W t is automatically operated. ``Continuous'' is the automatic display that displays the automatic status, and the summer time display (the sun mark on the right side of the program setting mode display) indicates that it is summer time when daylight saving time is set. The operating section of this time switch is equipped with a power display 15 that indicates the state of power supply and an output display 16 that indicates the state of output to the load.

The operation of setting the period and starting day of the week using this operation unit will be described below. The setting of the period during which the load 7 is turned off is selected by pressing the mode switch SW. When this period setting mode is entered, a second
As shown in Figure 7(a), “HO” indicates the period setting mode.
The characters "-1" are displayed in the minute display section to indicate where to set the setting period. Then, when the select switch SW1□ is turned on, the "-1" will be switched to 2 Hz) as shown in FIG. 27(b), indicating that the period can be set. Press the set switch SW, , to set an arbitrary period as shown in FIG. 27(e). Note that this time switch allows you to set up to a maximum of 99 days, and if you keep pressing the set switch 5W13 for 1 second or more, the numerical value will be fast-forwarded at 8 Hz.

After setting this period, when you press the select switch SW, the day of the week display indicating Monday, which is the day of the week when this off period setting was entered, will be displayed. ), indicates that the start day of the week is set and ends.Then, press set switch SW, ff to select any other day of the week except Monday.In other words, use this time switch to set the start day of the week. (over 1
You can choose from days of the week. Here, a case is shown in which the meeting date is selected as shown in FIG. 27(e). After setting the period and starting day of the week, the setting of the period and starting day of the week is completed by switching to the steady mode with the mode switch SW. At this time, as shown in Fig. 27(f), the current time and the current operating state of the load 7 are displayed, and the "Meeting" display indicating the starting day of the week is linked (O, 5Hz). , it can be seen that the period during which the load 7 is turned off has been reserved.

Assuming that the set start day of the week has now arrived, Figure 27 (
As shown in g), the day of the week display “Meet” stops blinking,
The "OFF" display blinks (0.5 Hz), indicating that it is time to turn off the load 7. For example, if the load 7 is set to be turned off continuously using the manual switches S W and When a so-called permanent off operation is performed, as shown in FIG.
This makes it possible to distinguish between the OFF state of the load 7 and the OFF state of the load 7 according to the period setting. In addition, when performing the permanent off operation,
"Off" display does not blink.

By the way, the period during which the load 7 is turned off can be changed by an operation substantially similar to the period setting operation described above. Note that if the set period has already been reached when making this change, there is no need to set the start day of the week, so as shown in Figure 30,
The day of the week is not displayed. In addition, in the display state of display fyIs13 in the period setting mode, for example, 2
If it exceeds 4 o'clock, the numerical value indicating the remaining period shown in FIG. 31(a) is decremented by 1 as shown in FIG. 31(b).

In addition, FIG. 31 shows a case where 24 o'clock has passed on the last day, and in this case, the minute display part becomes r--J.

[Effects of the Invention] As described above, the specified invention includes a program control means for operating a load according to a preset program, a period setting means for setting a period during which the load is turned on, and a setting performed by the period setting means. a setting detection means for detecting that the
A timer means for timing the set period set by the period setting means, and a timer means for keeping the load in an on state during the timer operation period of the timer means, and operating the load according to the output of the program control means after the set period elapses. Since the output control means is equipped with an output control means for controlling the output, when the period for turning on the load is set by the period setting means, after the set period has elapsed, the control state is automatically returned to the state controlled by the program control means, and one-time control by the period setting means is provided. The load can be temporarily turned on simply by setting the settings, making the operation easy and eliminating the need to forget to return to programmed operation.

In addition, a program control means for operating the load according to a weekly program consisting of a program preset for each day of the week, a period setting means for setting a period of several days during which the load is kept in an on state, and a period setting means for setting the period. a setting detecting means for detecting that the setting has been made by the means; a period determining means for determining the setting period set by the period setting means; and a period determining means for determining the on period according to the output of the period determining means and the program control means On-period setting means to be set, and output control that controls the operation of the load according to the output of the on-period setting means during the set period, and according to the output of the program control means after the set period has elapsed. and the on-period setting means turns on the load at the start of the set period if the output of the program control means is in a state to turn on the load at the start date of the set period. If the output of the program control means turns off the load at the start of the on period and the start date of the set period, the program control means turns on the load for the first time within the set period. If the output of the program control means is in a state to turn on the load at the end of the last day of the set period, the end of the set period is taken as the end of the on period, and If the output of the program control means is in a state where the load is turned off at the end of the last day of the set period, the output point of the program control means that turns off the load on the last day of the set period is set as the on period. By repeatedly setting the ON period at the end of the program, the load can be easily turned on even with a time switch that controls the operation of the load according to the weekly program, and forgetting to turn it off can be prevented. Note that, as in this case, the on-period setting means sets the period during which the load is actually turned on according to the output of the period determining means and the program control means, so even within the set period, the load may be turned on unnecessarily at midnight, for example. This makes it easier to use.

Further, if the period setting means can set a starting day of the week for a period of several days during which the load is kept on, and a starting day of the week determining means is provided for determining the starting day of the week set by the period setting means, You can schedule the load to be turned on for several days several days in advance.

In addition, the 1SiI series of inventions further includes a program control means for operating the load according to a weekly program consisting of a program preset for each day of the week, and a period setting means for setting a period of several days in which the load is kept in an off state on a daily basis. , a setting detecting means for detecting that a setting has been entered by the period setting means, a period determining means for determining the setting period set by the period setting means, and a period determining means for determining the setting period set by the period setting means, and according to the output of the period determining means and the program control means. an off-period setting means for setting an off-period using and an output control means for controlling the off-period setting means,
If the output of the program control means is in a state to turn off the load when the start date of the set period arrives, the set period is set as an off period for turning off the load, and when the start date of the set period arrives, , if the output of the program control means turns on the load at α, the off period is from the first time the program control means turns off the load within the set period to the end of the last day of the set period. Therefore, by simply setting a period of several days during which the load is to be turned off using the period setting means, the off period setting means can be used to set the start date of the set period when the load needs to be turned on over a holiday. The off-period setting means can be used to determine when the load is off and set the off-period to deal with cases where it is necessary to turn on the load over holidays. By setting the off period, the load can be automatically turned on before the start of work after holidays, resulting in labor savings.

In addition, if the period setting means can set the starting day of a period of several days during which the load is kept in an off state, and a starting day of the week determining means is provided for determining the starting day of the week set by the period setting means. You can schedule the load to be turned off for several days several days in advance.

Further, by providing a manual switch for manually turning on and off the operation of the load, it is possible to cope with cases where it is necessary to temporarily turn on the operation of the load within the period when the load is turned off.

Further, when the load is turned on during the off period by the manual switch, the load is turned off when the output of the program control means first turns off the load after the manual switch is operated. You can prevent forgetting to turn off the switch when turning it on using the manual switch.
