Next, press the minute switch 20 to set the minute digit display section 22 of the display 17 to a predetermined time. Then, when the current time switch 18 is pressed, the two sets of programs are stored, and the display on the display 17 returns to displaying the current time.

Problems to be Solved by the Invention However, as mentioned above, conventional time switches are extremely complex and difficult to operate because one switch is used many times for different purposes.

The present invention is a time switch that solves the above-mentioned conventional problems, and allows the setting of reserved times to be easily performed with a few switch operations.At the same time, by displaying the reserved times in a strip, the power supply schedule for the day can be confirmed at a glance. It provides:

Means for Solving the Problems In order to solve the above-mentioned vIB, the time switch of the present invention includes: a clock section consisting of a number display element and a plurality of dot display elements; a timer display section that displays the scheduled energization time for 24 hours; It is composed of two switches for setting the current time and three switches having the function of setting the display on the timer display section.

Effect of the present invention With the above-described configuration, the scheduled energization time, which is preset by the feed switch and the set switch,
While displaying a part of the 24-hour timer using display elements continuously arranged in a circular shape, automatic control is performed according to the current time of the clock section set by a separately provided time setting switch.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 shows the display and operation parts of the time switch of the present invention. In FIG. 0, 1 is a current time display, 2 is a display element on the timer partial display indicating 12:00 a.m., and 3 is the time on the timer display. This is the display section.

First, to set the current time, either the forward switch lO1 or the reverse switch 11 for time setting is pressed. When the forward switch 10 is pressed, the minute digit 9 of the time display 1 is incremented one minute at a time, and after 59 minutes, the hour digit 8 is incremented and added. Similarly, the AM display 6 and the PM display 7 are also lit alternately every 12 hours.

When the reverse switch 11 is pressed, the minute display section 9 is decremented by 1 minute, and the hour display f! is similarly displayed after 0 minutes. The hourly digits of AS are gradually decreasing. Therefore, if you set the current time using either the forward switch lO1 or reverse switch 11 for time setting and stop operating the switch, the time on the time display will start approximately 5 seconds later, and the dot display 15 will start displaying at 1 second intervals. Start blinking. In this way, you can easily set the current time using two switches.

Next, set the timer. When you press the timer setting feed switch 12, the 12 o'clock display element 2 of the timer display starts flashing. When you press the feed switch 12 again, the display element of the above display starts blinking at the 1 o'clock mark. , moving around 2 o'clock.

Then, when the set switch 13 is pressed while the blinking has moved to the time slot for which the energization reservation is desired, the display element that was blinking lights up, and the display element of the next time slot starts blinking. As mentioned above, press the set switch 13 for the time block for which you want to reserve energization using the feed switch 12 and set switch 13, and use the feed switch 12 to advance the time block for which you do not want to be energized, so that the timer display shows the energization status in a band shape. Is displayed. Also, if you want to change the energization reservation that has been set and increase the energization time period, you can perform the above set operation once again and increase the reservation time using the set switch 13, but if you want to decrease the energization time period, you can cancel the entire operation. When the switch 14 is pressed, all the timer indicators are turned off and the no-reservation state is entered, so the feed switch 12 is pressed again and the above-mentioned energization and reservation operations are repeated.

FIG. 2 is an example of an electrical connection diagram of a heating device using the above-mentioned time switch. In the figure, 31 is an AC power supply for a heater, 32 is an earth leakage breaker, and 33 is a heater for heating. The time switch circuit 35 is operated by the control power supply 34, and closes the contact 36 when the current time of the time switch reaches the scheduled energization time period of the timer. Then, current flows from the control power source 34 to the relay box 38, closing the contact 37 in the relay box 38, and supplying ts to the heater 33, thereby performing heating.

Effects of the Invention As described above, the time switch of the present invention provides the following effects.

(1) Since the present time and the timer reservation time are each provided with independent display means, the timer reservation time is always displayed while the current time is displayed, giving a sense of security in use.

(2) It is possible to set the number of times in one day that the ON time and OFF time are equal to half of the number of timer display elements. In other words, if one display is displayed per hour, the settings can be made up to 12 times a day, making the above settings easy to see, making this a highly convenient time switch.
