Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time switch used for controlling on / off of a load according to a set program, and more particularly to a so-called weekly time switch which can be set for each day of the week.

[0002]

2. Description of the Related Art A time switch gives an on output or an off output to a load device at a set time and starts or stops the load device, and is used for controlling the operation time of the device or the like. .

Such a time switch includes a so-called weekly time switch which can be set for each day of the week on a weekly basis.
A program is set to grasp the date as a day of the week, and for each day of the week, for example, from Monday to Friday, the operation time (on time) is from 8:30 to 17:30, and on Saturday and Sunday, the program is set to non-operation. And the on / off control of the load is performed in accordance with the set program.

[0004] In such a weekly time switch, there is no problem if the same control is performed every week, but when there is a holiday or a long vacation, for example, the next Monday is shut down from one week before immediately. In the week after the holidays, the changed program was restored, or the output was manually forcibly turned off on holidays and the like.

In a weekly time switch having a weekday transfer function for returning a control operation on a certain day of the week to a control operation on another day, a non-operation program is set on a holiday, for example, on a Monday. Holidays, etc. were made non-operational by changing Saturday or Sunday.

[0006]

As described above, in the conventional weekly time switch, the date is grasped by the day of the week and the setting is made on a weekly basis. Can not be changed or the day of the week can be changed, so, for example, if the program cannot be changed or the day of the week cannot be changed several months before the scheduled vacation, and if the vacation is longer than one week, It is difficult to change the program or change the day of the week.

[0007] Further, there is a disadvantage that if the changed program is forgotten to be returned, the operation start of the week after the holiday is delayed.

Therefore, it is conceivable to use an annual early time switch for grasping the date as the date itself instead of grasping the date on the day of the week. However, the setting operation is troublesome because it is necessary to set a program for the year. However, it is inconvenient and expensive.

The present invention has been made in view of the above-mentioned conventional problems. In a weekly time switch in which a program can be set for each day of the week, it is possible to easily change a program on a day ahead of one week or more. The main object of the present invention is to allow the user to perform the operation by operation, and also to prevent the user from forgetting to return the changed program.

[0010]

In order to achieve the above-mentioned object, the present invention is configured as follows.

That is, the time switch of the present invention turns on and off the output according to a set program, and the time switch in which the program can be set for each day of the week sets the day when the program should be changed as what day of the week. On the other hand, when the change program is set, the output is turned on / off according to the change program when the set day of the week corresponds to the set day of the week.

Here, what day of the week means how many days ahead the day on which the program should be changed is based on the day on which the day on which the program is to be changed is set. In the present invention, what number of days of the week includes what day of the week, what day of the week, or what day of the week.

According to the present invention, in a so-called weekly time switch in which a program can be set for each day of the week, that is, in a weekly time switch in which a date can be recognized only as a day of the week, the date on which the program is to be changed is set to what number Since the day of the week is set, the program of the day of the week one week or more can be changed, and there is no problem that the program cannot be changed until one week before, unlike the conventional case.

In one embodiment of the present invention, the output is turned on and off in accordance with a set program, and the time when the program is to be changed is determined by a time switch which can be set for each day of the week as what day of the week. A setting unit on which the change program is set, a storage unit for storing the setting contents of the setting unit, and a corresponding day of a week corresponding to what number of days of the week stored in the storage unit Determining means for determining whether or not has arrived, and when it is determined that the corresponding day of the week has arrived, the output is turned on / off according to the change program, and the corresponding day of the week has elapsed. After that, the control for erasing the settings stored in the storage means and turning the output on and off in accordance with a preset program And a stage.

The settings to be deleted after the corresponding day of the week has passed may be the setting of what day of the week, a change program, or both. May be.

According to the present invention, in the weekly time switch in which the date can be recognized only as the day of the week, the day when the program is to be changed is set from the setting means as the number of the day of the week. After the control is performed by the changed program, the changed program stored in the storage means is deleted by the control means and controlled according to a preset program. There is no need to undo.

In a preferred embodiment of the present invention, each time the day of the week set as the day of the week arrives, 1 is subtracted from the number set as the number of the day of the week to arrive at the day of the week. It is to determine whether or not.

According to the present invention, in the weekly time switch in which the date can be recognized only as the day of the week, the day when the program should be changed is set as the number of times each day of the week set. When 1 is subtracted from the number of times and the result of the subtraction becomes 0, it is determined that the date to change the program has arrived, thereby simplifying the day to change the program one week or more ahead. It can be determined by a simple process.

In a further preferred aspect of the present invention, the change program is a non-operating program for turning off the output.

According to the present invention, since the change program is a non-operation program that turns off the output, it is possible to make a change setting of a holiday such as a public holiday or a long vacation one week or more ahead.

In another embodiment of the present invention, a holiday setting key for setting the change program is provided.

According to the present invention, it is possible to easily change and set a program for a holiday such as a public holiday one week or more or a long holiday.

[0023]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a front view of a time switch according to one embodiment of the present invention, and FIG. 2 is a block diagram of the inside thereof.

On the front of the time switch 1, the day, hour,
A display unit 2 made of liquid crystal for performing various displays such as minutes or scheduled operation times is provided. Around the rectangular display unit 2, a feed key, a selection / cancel key,
Various operation keys 4 such as a set key are provided. Particularly, in this embodiment, a holiday setting key 5 is added so that a holiday such as a holiday one week or more or a long holiday can be easily set. ing. As shown in FIG. 2, the time switch 1 includes a clock unit 6 for measuring the current time, a memory 7 for storing settings from the setting unit 3, and an output unit for providing an on / off output to a load device. 8 and a CPU 9 for controlling each unit.

The time switch 1 is a so-called weekly time switch in which a program can be set for each day of the week from Sunday to Saturday. In this embodiment, one of the weekly time switches in which the date can be grasped only by the day of the week is used. The following configuration is used to make it easy to change program settings for holidays such as public holidays or long-term vacations that are longer than a week.

That is, in this embodiment, the day when the program is to be changed is set as the number of times (how many days ahead) and the day of the week based on the day when the program change setting is made. For example, in the calendar A shown in FIG. 3, it is assumed that the current date is December 7 (Tuesday), the holiday on December 23 (Thursday) and December 2 (Thursday).
9th (Wednesday), 30th December (Thursday), 31st December
The following describes an example of setting holidays for the year-end and New Year holidays on Sunday (Friday), January 3 (Monday), and January 4 (Tuesday).

A program for setting the operating time (ON time) from 8:30 to 17:30 from Monday to Friday and a program for setting non-operation (holiday) on Saturday and Sunday are set in advance. I have. In FIG. 3, days when non-operating programs are set in advance are circled, and holidays for setting holiday programs and holidays during the year-end and New Year holidays are surrounded by rectangles.

Assuming that the program is to be changed and set as of December 7 (Tuesday), the holiday of December 23 (Thursday) will be the next next day based on this December 7 (Tuesday). , That is, the third Thursday, and similarly, on December 29 (Wednesday), December 30 (Thursday), December 31 (Friday), January 3 (Monday), and January 4 (Tuesday) New Year holidays
The fourth Wednesday, Thursday, Friday, Monday and Tuesday.

Therefore, in this embodiment, for example, a change of holiday is set in accordance with the following operation procedure. First, in a state where the normal operation screen is displayed on the display unit 2, when the above-described holiday setting key 5 is pressed for one second or more, a holiday setting mode is set, and the holiday setting screen is displayed on the display unit 2. In this holiday setting mode, a required key such as a feed key is operated, and as shown in FIG. 4, a numeral 3 indicating the third time and a cursor blinking at a position corresponding to Thursday are displayed. The (Thursday) holiday is set as the third (third) Thursday as a holiday.

Similarly, on Wednesday, December 29, 1
New Year holidays on Thursday, February 30, Friday, December 31, January 3 (Monday) and January 4 (Tuesday) have been closed for the fourth Wednesday, Thursday, Friday, Monday and Set each holiday as Tuesday.

In the setting of the holiday, by operating the holiday setting key 5, a non-operating (holiday) program for turning off the output all day is also set as a change program. Note that the set contents can be monitored and confirmed on the display unit 2 by a required key operation.

After the holiday has been set in this way, when the holiday setting key 5 is depressed for one second or more to return to the normal operation mode, the same operation as the conventional operation is performed, but the holiday is set. Each time the day of the week arrives, 1 is subtracted from the number of times set.

For example, as shown in FIG.
At the time of setting the day (Tuesday), Thursday, December 23
Is the third Thursday, December 29 (Wednesday), 1
February 30 (Thursday), December 31 (Friday), January 3 (Monday) and January 4 (Tuesday) are set as the fourth Wednesday, Thursday, Friday, Monday and Tuesday, respectively. I have.

For example, on Wednesday, December 15, the next week after Tuesday, December 7, Thursday, Friday,
Since Saturday, Sunday, Monday and Tuesday have come once, respectively, December 23 (Thursday) is the second Thursday, and December 30 (Thursday), December 31 (Friday) and January 3 The set number of days (Monday) and January 4 (Tuesday) are subtracted as the third Thursday, Friday, Monday and Tuesday, while Wednesday has arrived twice, so that Wednesday, December 29 (Wednesday) However, the set number is subtracted as the second Wednesday.

Further, for example, on Tuesday, December 28
At the time of, December 23 (Thursday) has already passed, and December 29 (Wednesday), December 30 (Thursday), December 31 (Friday), January 3 (Monday) and January 4 (Tuesday) is the first Wednesday, Thursday,
The set number is subtracted for each of Friday, Monday, and Tuesday.

When the result of the subtraction becomes 0, it is determined that it is a date to change the program, and the set non-operational program is executed. Then, after the date to be changed has elapsed, the changed program is deleted and the program returns to the preset program.

In this way, when the set day of the week (how many times ahead) arrives, the non-operation (holiday) program is executed.

This makes it easy to change the program for a holiday or a long-term vacation one week or more ahead. For example, the program can be changed and set immediately when the vacation is scheduled several months before the holiday. So you can
Never forget to change program settings.

Further, in the past, in the case of a long vacation exceeding one week, the program could only be changed one week before. Therefore, the program could not be changed only once, but in this embodiment, It is possible to set a long vacation longer than one week at a time.

In addition, since the non-operating change program is set by operating the holiday setting key 5, it is not necessary to change the preset program main body as in the prior art, and the operation can be easily performed.

Further, there is no need to restore the program changed after the holidays, and there is no inconvenience that the operation start is delayed by forgetting to restore the changed program as in the related art.

FIG. 6 is a flowchart for explaining the above-mentioned operation. First, the above-mentioned holiday setting mode is set (step n1), and the number of days on which the program should be changed (first) is set.
The program is set in the normal operation mode (program operation mode) (step n3), for example, to determine which day of the week is set as, for example, the a-time b day (step n2). Judgment (step n
4) When b is the day of the week, the result of subtracting 1 from a is set as a new a (step n5), and it is determined whether the new a has become 0 (step n6). Assuming that the program is to be changed, the output is turned off according to the non-operation (holiday) program (step n7), and the above-mentioned a and b, which are holiday setting data corresponding to that day, are cleared (step n7). Step n
8). It should be noted that a and b described above can set a plurality of sets, that is, a plurality of holidays.

In the above-described embodiment, the change program is a non-working holiday program.
The present invention is not limited to a non-operating program, but may be an operating program. For example, at the time of program change setting, an operation time program may be set together, and similarly to the above-described embodiment, what number of operation days may be set.

In the above-described embodiment, after the date on which the program is to be changed has elapsed, the changed settings are automatically cleared, and the program is returned to the preset program and controlled. As another embodiment, the settings changed by the operation may be deleted and the program may be returned to a preset program.

[0046]

As described above, according to the present invention, the program should be changed in a so-called weekly time switch in which a program can be set for each day of the week, that is, in a weekly time switch in which a date can be recognized only as a day of the week. Since the day is set as what day of the week, the program can be changed one week or more ahead, and there is no problem that the program cannot be changed until one week before, unlike the conventional case.

After the control by the changed program is performed, the control is returned to the preset program and the control is performed. Therefore, there is no need to restore the changed program, and the changed program can be used as in the prior art. There is no inconvenience such as delaying starting operation by forgetting to restore.
