ABSTRACT:

FIELD AND BACKGROUND OF THE INVENTION
The present invention relates to a time period setting device for a timer, with which several pre-set time periods can be set. The present application denotes especially a device for setting “Hour” and “Minute.
There are many setting modes for conventional timers in the market, such as mechanical (setting via striking keyboard is general) and electronic (using key for controlling). There are a variety of timers, including mechanical setting which is an easier setting, but the divisions of each time period is larger. In other words, one can only make a coarse setting of the time period. For electronic setting, the usable space on the setting disk is not large, because there are many keys therein. Thus, one who does not know the operation well, or whose fingers are large, easily makes an erroneous setting, and it's more difficult in operation. The present application is an electronic timer, for smaller numeral changes, such as setting ON/OFF, setting switching timing/present time, “week X” ext, which are controlled by the keys, and for two larger numeral changes, such as “Hour X” and “Minute X”, which are set by means of rotating a rotary disk.
SUMMARY OF THE INVENTION
The object of the present application is to provide a device for setting the time period; it general operating condition as are noted below:
1. function: setting time ON/OFF for several groups; timing 1-7 days.
2. Program mode: divided into displaying present time (clock) and setting time period.
3. Function of the keys:
a. Clock mode-displaying present time mode,
(a-
1
) key “ON/OFF”: switching ON/OFF output,
(a-
2
) key “Clock +Day”: regulating present week (MO-SU),
(a-
3
) key “Clock” +rotary disk rotated clockwise: regulating “Hour” for present time,
(a-
4
) key “Clock” +rotary disk rotated counter clockwise: regulating “Minute” for present time,
(a-
5
) key “Timer”: entering into program mode.
Under clock mode, key “Day” and rotary disk are clock wise/counter clockwise rotated, alone use will be without function, the function to be produced must match key “Clock”,
b. program mode: setting time mode,
(b-
1
) key “ON/OFF”: without function,
(b-
2
) key “Day”: regulating day (of week) of timer ON/OFF. there are 11 settings for date, such as MO, TU, WE, TH, FR, ST, SU, MO-FR, SA-SU, MO-SA, MO-SU,
(b-
3
) rotary disk rotated clockwise: setting time “Hour” of timing function,
(b-
4
) rotary disk rotated clockwise: setting time “Minute” of timing function,
(b-
5
) key “Timer”: ON/OFF time setting switching (1 ON→1 OFF→2 ON→ . . . →6 OFF) of 6 groups ON/OFF for timing function,
(b-
6
) key “Clock”: returning clock mode,
c. key “Reset”: all memories are cancelled when the key “Reset” is depressed whether it is under clock or program mode, and the program is again started.
As above-mentioned, the characteristics of the present application are to provide a structure setting “Hour X” and “Minute X”, in which setting the Hour/Minute is operated by clockwise or counter-clockwise rotation, without the necessity for setting many keys on a dial, such that the erroneous position produced at the time setting “Hour” and “Minute” can be avoided.
The technical solution of the present application is that, a rotary disk is provided in the outer edge, with a ringed structure having several projecting teeth driven by rotating the rotary disk, and a sliding structure which can be moved to right/left by stirring the projecting tooth. A circuit contact structure is provided on the sliding structure, whereby the Hour/Minute can be quickly set by means of a contact (producing pulse) time on the special area of the circuit board for the structure.
The circuit part of timer in the present application will not be described since it belongs to a conventional technical field.
