Description

[Detailed description of the invention] (Field of application of the invention) The invention relates to an improvement of an electronic time switch that stores on-time and off-time and controls the on/off of a load according to these times. . The electronic time switch of the present invention includes an electronic solar time switch.

(Background of the invention) Time switches repeatedly control loads every day based on memorized on and off times, so demand for them is steadily increasing in various industrial equipment and office machines, and their use will continue in the future. It is expected that the range will expand.

Generally, when used for industrial equipment, etc., some equipment does not operate on holidays, so the skip date on which the equipment is not operated is specified using a skip date designation means such as a switch, and the time is measured using the skip date and a calendar/clock timing means. The method used was to skip control when the day of the week matches the day of the week.

However, with this type of time switch, all output circuits are turned off on the skip date, so for example, if a pump and an air conditioner are to be controlled, the pump is operated only during the daytime every day, and the air conditioner is turned off. If you want to turn off the air conditioner on holidays such as Saturday and Sunday, specifying the holiday as a skip day will cause the pump to stop on the holiday. Conversely, if you do not specify a holiday as a skip day, the air conditioner will not operate on the holiday. This will result in As a result, there were problems such as not being able to do what was needed and wasting energy.

(Purpose of the invention) The purpose of the invention is to solve the above-mentioned problems and provide an electronic time switch that can skip or not skip control on the skip date depending on the load. be.

(Characteristics of the invention) In order to achieve the above object, the present invention provides skip selection means for selecting whether or not to apply the skip date designated by the skip date designation means for each of a plurality of output circuits. So, on the skip day,
The present invention is characterized in that only the output circuit selected by the skip selection means is controlled to be turned off all day long.

(Example of idea) FIG. 1 shows a front view of an embodiment of the present invention.

The rotary switch 1 is operated when setting or confirming the setting contents, and the push button switch 2 consists of first to third push button switches 2a to 2c.
The switches 1 and 2 are operated when inputting settings or confirming settings, and both switches 1 and 2 constitute setting input means 3 (FIG. 2).

The clock display 4, which uses a 7-segment display, etc., uses the first clock display when inputting settings and confirming settings.
and displaying the control pattern number of the second output circuit, the on time and the off time of the three control patterns,
If the rotary switch 1 is in the driving position, the current time is displayed. The day of the week indicator 5, which is made up of seven light emitting diodes corresponding to each day of the week, displays the day of the week of the set date when inputting settings and confirming the settings, and displays the day of the week during operation. If you want to turn off the day of the week switch 6, which is made up of seven switches corresponding to each day of the week, all day of the week (the load can be turned on manually)
By switching to "off", a skip day is designated for that day of the week, and corresponds to the skip day designation means of the present invention. Weekly control selection switch 7
Is the skip day caused by turning off the day switch 6 applied only to the first output circuit as shown in FIG. 3A, or applied to the second output circuit as shown in FIG. 3B?
This function corresponds to the skip selection means of the present invention, and selects whether to apply only to the output circuit of 1 or to both output circuits as shown in FIG. 3C. The load control switch 8 includes a first load control switch 8a and a second load control switch 8b.
The load connected to the first and second output circuits is forcibly turned on and off by manual operation. Output status indicator light 9 consisting of a first output status indicator light 9a and a second output status indicator light 9b
are for displaying the states of the first and second output circuits, respectively.

FIG. 2 is a block diagram showing the configuration including the internal mechanism of one embodiment of the present invention.

The calendar/clock timing means 10 measures the current day of the week and the current time, and the memory means 11 stores setting data input from the setting input means 3, the skip day (day of the week) designated by the day of the week switch 6, and weekly control selection. A device for storing the number of the output circuit selected by the switch 7 and the "on" and "off" states of the load control switch 8, etc., the calculation means 12 consisting of a microprocessor, etc., and performing necessary calculations;
The output means 13 turns on or off the first and second output circuits.

First, the settings will be explained.

To set the current day of the week and current time, rotate the rotary switch 1 clockwise: align the rotary switch 1 with the day of the week and the clock mark, and set the time digits displayed on the clock display 4 to the first pushbutton switch. 2a and the second pushbutton switch 2b to match the current time on the set date, and the lighting position of the day of the week indicator 5 to be set to the day of the week on the set date by operating the third pushbutton switch 2c.

When setting the output circuit control pattern,
Rotary switch 1 position is output 1 or output 2
The number of the control pattern displayed on the clock display 4 is selected by operating the second push button switch 2b.

Up to three control patterns can be set. When setting a control pattern, the rotary switch 1 is positioned to match the set of patterns 1 to 3, and the on and off times are set by operating the push button switches 2a to 2c.

During operation, set the rotary switch 1 to the operating position.

To explain the operation operation, on days of the week that are not skip days, the calculation means 12 uses the current time input from the calendar/clock timing means 11 as the ON time and OFF time of the control pattern for each output circuit read from the memory means 11. Compare and output means 1 when they match
Each output circuit of No. 3 is controlled to an on or off output state.

When the day of the week designated as the skip date, for example Sunday, comes, if the weekly control selection switch 7 is switched as shown in FIG. 3A, the calculation means 12
In this case, the on-output control is stopped for the first output circuit and turned off all day, and the on-off control for the second output circuit is controlled according to the set control pattern.

(Correspondence between the invention and the embodiment) In the illustrated embodiment, the day of the week switch 6 is used as the skip date designation means of the invention, the weekly control selection switch 7 is used as the skip selection means of the invention, and the day of the week is used as the calendar day of the invention. Equivalent to.

(Modification) In the illustrated embodiment, the day of the week is designated as the skip date, but it is also possible to designate the day. In this case, the month and day become calendar days.

The number of output circuits can be three or more.

For electronic solar time switches, if it is a day other than a holiday, or if it is to be turned on continuously from sunset to sunrise the next day on a holiday, the switch will turn on from sunset to sunrise the next day. The period up to the end of the day is treated as a skip date.

(Effect of the invention) As explained above, according to the invention, a skip selection means is provided for selecting whether or not to apply the skip date designated by the skip date designation means for each of a plurality of output circuits. So, on the skip day,
Since only the output circuit selected by the skip selection means is controlled to be turned off all day long, control can be skipped or not skipped on the skip day depending on the load.
