Description

[Detailed description of the invention] This invention relates to a programmable timer device.
This particularly concerns the display section.

Programmable timer devices for programmatic operation of air conditioners, etc. do not require very high time resolution; a time resolution of about 1 hour to 30 minutes is sufficient, and usually one day, In other words, it is sufficient to be able to set a 24-hour program, and after 24 hours have passed, the program may be reset manually or automatically.

FIG. 1 is an explanatory diagram showing the configuration of a display section and a program setting section in a conventional device of this type of programmable timer, and in the figure, 23 is a display section with N pieces (N=24 in the example shown in the figure). light emitting elements are arranged in a straight line. Each light emitting element is
24/N corresponds to the time of the hour, i.e. from 0 to 1 o'clock,
It corresponds to each hour from 1 to 2 o'clock, from 2 to 3 o'clock, and so on. Furthermore, the light-emitting elements, which are displayed as black and white with a diagonal line as a boundary, as shown by numeral 3, periodically repeat the state of emitting and stopping light emission, that is, the light-emitting elements that are blinking are shown as numeral 4. A light-emitting element indicated by hatching indicates a light-emitting element that continuously emits light, and a light-emitting element indicated by a hollow symbol 5 indicates a light-emitting element which stops emitting light. The light emitting element 3 indicates the current time, the light emitting element 4 indicates the time during which the power supply is connected to the load under program control (referred to as timer on time), and the light emitting element 5 indicates the time during which the load is disconnected from the power supply (referred to as timer off time). shall be shown. In addition, the numbers written on the display section 23 represent the time, for example, the number 18 indicates 18:00 (6 p.m.
time).

The program setting section is shown in Figure 1 as A, B, C, D,
It is equipped with five sets of sliding setting devices indicated by letters E and F, each set of setting devices is provided with setting indicators 201 and 202, and a display 23 corresponding to the setting indicator 201 is provided.
The timer turns on at the time of , and the setting index 202
The timer is connected so that the timer is turned off according to the time on the display 23 corresponding to the time.

In the example shown in the figure, setting device A turns the timer on at 9 o'clock and turns it off at 3 o'clock, setting device B turns the timer on at 5 o'clock and turns it off at 6 o'clock, and setting device C turns the timer on at 7 o'clock and turns it off at 9 o'clock.
The timer is turned off at 11 o'clock and the timer is turned off at 13 o'clock according to the setting of the setting device D, and the timer is turned on at 15 o'clock and the timer is turned off at 19 o'clock according to the setting of the setting device E.

Furthermore, the current time can be adjusted using a switch, etc. (not shown).
A blinking (periodic repetition of light emission and stop of light emission) display 3 is displayed on the display 23.

After setting the timer on time and timer off time and adjusting the current time in this way, when a command to start operation is given by a switch or the like (not shown), the settings will move sequentially to the programmed and displayed settings. The program operation of the load (not shown) such as an air conditioner is performed by comparing the current time displayed on the screen.

The drawback of the programmable timer device configured as described above is that it requires a large number of setters, and although five sets of setters A to E are shown in Figure 1, it is composed of N light emitting elements. A maximum of N/2 sets of setting devices are required for the display device, which poses problems such as an increase in volume and price, deterioration in operability, and deterioration in reliability. Also, if the program has a small number of on/off cycles within a 24-hour period, there will be setting devices that are not used.
Another disadvantage was that the processing method and other factors further reduced operability.

The purpose of this invention is to eliminate the above-mentioned drawbacks of conventional devices, and for this reason, this invention uses circuit elements with binary functions such as switches, etc., for program setting, and various types of information from these circuit elements. The set position display is performed on the display section in response to a signal, and the set position display is sequentially transferred onto each light emitting element to facilitate program setting.An embodiment of this invention will be described below with reference to the drawings.

FIG. 5 is an explanatory diagram showing changes in the display on the display 23, in which a shows a new program to be set, b shows a previously set program, and c to n show each program. The light emission of the light emitting element at the time point is shown. Although the light emitting state indicated by the reference numeral 6 is blinking, it has a blinking cycle different from that of the current time display 3, so that it can be easily distinguished and the setting position is displayed.

The operation of the device of this invention will be described above with reference to FIGS. 2 to 5. An example in which the operating program shown in FIG. 5a is newly set when the operating program shown in FIG. 5b is being executed will be explained. The program shown in FIG. 5b is displayed as shown in FIG. 5c, and the clock in the control circuit 103 is out of order.
Suppose that indicates 4 o'clock and the actual time is 14 o'clock. This is the situation at the timing shown in FIG. When the current time adjustment switch 11 is pressed as shown in FIG. 4a, the current time advance pulse shown in FIG. Therefore, when 10 pulses are generated, the current time display 3 is transferred to the light emitting element corresponding to 14:00. If the switch 11 is released at this time, the current time adjustment is completed, and therefore, at the timing shown in FIG. 4, the state of the display 23 becomes as shown in FIG. 5d.

In the embodiment described below, the setting position display 6 includes a setting position display switch 12, a timer-on setting switch 13, and a timer-off setting switch 14.
It is assumed that the design is such that the signal is generated when any of the switches is pressed, and that the signal is generated first in the light emitting element of the current time display 3 and then sequentially moves on the light emitting element. As shown in Figure 4b, when switch 12 is pressed, the fourth
The set position feed pulse shown in FIG. 5H is generated, but at the time after three of these pulses have been generated, that is, at the timing shown in FIG. 4, the state of the display 23 becomes as shown in FIG. 5E. If the switch 12 is continued to be pressed further, the state shown in FIGS. 5f to 5g will occur. From 14:00
Until 20:00, the previous program (Figure 5 b) was followed, so I pressed switch 12.
Since the program from 21:00 is different from the previous program, release the switch 12 and press the timer on setting switch 13. The sending pulse for displaying the set position is generated at the same time as the switch 12 is pressed (Fig. 4h), and the light emitting element that has displayed the set position 6 displays the timer-on time 4, and the timer device has a corresponding program. is set. As shown in Figure 5a
Since it is sufficient to set the timer on time until 11 o'clock, the switch 13 is released when the light emitting element corresponding to 1 o'clock becomes the timer on time display 4 and the setting position display 6 moves to the next light emitting element. This point corresponds to the timing shown in FIG. 4 and is displayed as shown in FIG. 5h. Next, the switch 12 is pressed as shown in FIG. 4b, and at the timing shown in FIG. 4, the display becomes as shown in FIG. 5i.
In the program to be set (Figure 5a), 6
The timer will be off from 11:00 to 11:00, so the next time will be 4th.
As shown in Figure d, the timer off setting switch 14
Press. The display on the display 23 changes sequentially as shown in j, k, i in FIG. At the point indicated in Fig. 5 (timing shown in Fig. 4), switch 1 for setting the timer off is turned on.
4 and press the timer on setting switch 13.
If the timer ON setting switch 13 is released and the timer operation selection switch 15 is pressed when the display is as shown in FIG. 5m, the display becomes as shown in FIG. 5n and the setting of the new program shown in FIG. 5a is completed. Thereafter, as time passes, the current time display 3 moves and the display section 23
Programmed operation of the load 107 is performed according to the program displayed in .

In the above embodiment, the setting position indication 6 is generated from the position of the current time indication 3, but it may be generated from a light emitting element corresponding to a predetermined time. The operating procedures include time adjustment, timer on setting,
The timer off setting can be set according to the degree of necessity.

Furthermore, the timer-on setting switch 13 and the timer-off setting switch 14 have a program setting function and a function of simultaneously generating the setting position display 6 and activating its sequential movement, but the functions of the switches 13 and 14 are limited to program setting. In order to activate the set position display 6 and move it sequentially, the set position display switch 12 may be operated.

As mentioned above, according to this idea, there are 24/
The setting position is displayed using a display consisting of an array of N light emitting elements each corresponding to a time during N hours, and this setting position display is sequentially moved over the above N light emitting elements. By setting the timer on or off for the time during which the set position is displayed, a programmable timer device with good operability can be constructed at low cost. Further, since the setting position display can be simply moved without performing program settings, it becomes easy to partially modify the program. In addition, the number of parts is small, and the device can be made smaller and its reliability can be improved.
