【Example】

Embodiment 1 FIG. Embodiments of the present invention will be described below with reference to the drawings. 1 is a control circuit diagram of a timer operation control device for electric equipment according to the present invention, FIG. 2 is an operation panel diagram of electric equipment according to the present invention, and FIG. 3 is a flowchart showing an example of program control in the timer operation control device of FIG. is there.

As shown in FIG. 2, the operation panel of the electric device according to the present invention has an operation switch 1 for starting and stopping the operation, a timer switch 2 as a timer operation instructing means, time, temperature and the like. A digital display unit 7 for displaying, plus key 20 and minus key 2 as setting means for changing the contents displayed on the display unit 7.
1 and are provided.

As shown in FIG. 1, the control circuit is mainly composed of a microcomputer (hereinafter referred to as "microcomputer") 22, and the input side of the microcomputer 22 has an operating switch 1, a timer switch 2, a plus key 20, A minus key 21 and a thermistor 23 for detecting the room temperature are connected. In the microcomputer 22, an input circuit 22a that takes in these input information, a CPU 22b that performs control processing such as calculation and determination, a memory 2 that stores programs and data.
2c, an output circuit 22d for controlling an external load, an oscillator 24 such as a crystal oscillator is connected to the outside, and operates by a clock pulse generated from the oscillator 24. This clock pulse also acts as a time counting means for counting the current time. On the output side of the microcomputer 22, a display unit 7 and a heater that operates as a heater,
A load group 25 including a motor and the like is connected.

The timer means, the timer time storage means, the timer operation control means, the time setting timer and the mode control means in the present invention are constituted by the microcomputer 22.

Next, the operation of the control circuit having the above configuration will be described with reference to the flowchart of FIG. First, when the operation switch 1 is turned on, the heater starts operating (step 30), and the set temperature and the room temperature detected by the thermistor 23 are displayed on the display unit 7. At this time, the set temperature can be changed with the plus key 20 or the minus key 21, and the heater adjusts the combustion amount and the like so as to reach the set temperature.

Next, when the timer switch 2 is turned on (step 32), the time setting timer in the memory 22c of the microcomputer is cleared and counting is started (step 33). At the same time, the display of the display unit 7 displays the timer time. (Step 34). When the display unit 7 is displaying the timer time, it is in the timer time setting mode, and the timer time can be changed by pressing the setting switch of the plus key 20 or the minus key 21 (step 35) (step 36). ). In this case, the process returns to step 33 and the time setting timer is cleared again.

When the setting of the timer time is completed and the time setting timer has reached a predetermined value, that is, 5 seconds in this embodiment (step 37), the timer time setting mode is changed to the current time setting mode, and the display unit 7 displays the current time. Is displayed (step 38). In this state, if the present time is out of order or is not set, the setting switch of the plus key 20 or the minus key 21 is pressed (step 39) to change or set the present time.
Until the current time matches the timer time, the match determination between the current time measurement and the timer time is continued (step 4
3) The timer is on standby, and the display unit 7 continuously displays the current time.

When the current time matches the timer time (step 41), the microcomputer 22 operates the load group 25,
The timer operation is started (step 42). At this time, the display unit 7 changes to the temperature display required for the heating operation. Also,
The timer time for starting the operation may be a work time before the timer time defined by the room temperature or the like before the operation starts.

In this way, during the heating operation, the temperature is displayed, the timer switch 2 is pressed, the timer time is displayed for 5 seconds, and then the current time is displayed. Since the contents can be changed at any time by the setting switch of the plus key 20 and the minus key 21, only two switches for setting the temperature and time are required, and the operation panel is not only clean but the operability is good. The cost will be lower. Also, since the current time is displayed while the timer is on standby, it can be used as a clock, and the user can easily notice when the current time is out of order or is not set and operate the setting switch to set the correct time. Can be set.

Even if the heater is turned off and the set time disappears and it is necessary to reset it, after pressing the timer switch 2, the timer time is set and the display changes after 5 seconds. Since the time can be set in a series of timer set operations such as setting the current time, the operability is very good.

Further, in the present time setting mode, when it is desired to confirm the timer time or to change the timer time, the timer setting timer is cleared by pressing the timer switch 2 as shown in step 43 of FIG. The timer time setting mode for 5 seconds can be set again. By doing so, the current time is normally displayed, and the timer time can be displayed whenever necessary, which is convenient.

Embodiment 2 FIG. FIG. 4 is a modification of step 38 of FIG. 3, in which it is determined in step 38a whether the current time is not set, and when the current time is set, it is illuminated in step 38b, and when it is not set. This is an explanation of the display mode changing means that makes the blinking display at 12:00 in step 38c. By doing this, it is possible to reliably inform the user of the unset state of the current time, set the timer time in the state where the current time is not set, and wait for the timer operation setting operation to wait in the state of timer standby. It can be prevented.

Example 3. FIG. 5 shows another embodiment in which the part of step 39 in FIG. 3 is changed.
Alternatively, the delay means is described so that the present time can be changed when the setting switch of the minus key 21 is continuously operated for a predetermined time, that is, 2 seconds in this embodiment. By doing this, while the timer is on standby, it is always in the current time setting mode, but even if you accidentally touch the setting switch, the current time does not change immediately, so you may unknowingly change the current time. It can be used without anxiety.

[0029]

As described above, according to the present invention, when the timer operation instruction means is operated to perform the timer operation, the time setting timer is initialized, and the timer time is set until the timer reaches a predetermined value. Since it is equipped with a mode control means that enters the setting mode and becomes the current time setting mode when a predetermined value is exceeded, it is normally configured to display the current time and display the timer time only when necessary. The operability at the time of timer operation is good, and the number of switches can be reduced, so that the operation panel is refreshed and the cost can be reduced.

Further, in the current time setting mode, since the display mode changing means for changing the display mode of the display means when the current time is not set is provided, the timer operation does not fail and the usability is improved. .

Further, in the present time setting mode, when the present time is changed, the delay unit is provided so that it can be changed by continuously operating the setting unit for a predetermined time. Therefore, even if the setting unit is touched by mistake. Since there is no need to change the current time, you can use it with peace of mind and improve safety.
