Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timer control device having a clock function and setting and using a current time and a timer time.

2. Description of the Related Art In general, a timer control device that automatically starts operation of a device when a current time reaches a preset timer time, in addition to a clock display unit that displays time,
When setting the time, a switch for selecting whether to set the current time or the timer time and a switch for instructing to perform the timer operation were required. FIG. 3 shows an example of the conventional configuration. 100 is a clock display unit for displaying the current time and timer time. 101 is a non-locking time setting switch operated when setting the current time. When pressed once, the current time setting mode is set. The time setting mode is canceled. In the current time adjustment mode, the lamp 102 lights up to express the state. 103 is a non-locking timer setting switch operated when setting the timer time,
When pressed once, the timer time adjustment mode is set. When pressed again, the timer time adjustment mode is released. In the timer time adjustment mode, the lamp 104 lights up to express the state. Reference numeral 105 denotes a switch for setting the "hour" of the clock display unit 100, and reference numeral 106 denotes a switch for setting the "minute" of the clock display unit 100. The switches 105 and 106 receive the current time adjustment mode and the timer time adjustment mode. Reference numeral 107 denotes a non-locking timer switch that is operated when performing the timer operation. When the switch is pressed once, the timer operation is performed, and when the switch is pressed again, the timer operation is released. Ten
Reference numeral 8 denotes a lamp indicating that the timer is running. When the timer operation is performed in the above configuration, the current time and the timer time are set in advance by the time adjustment switch 101 and the timer adjustment switch 103, and the timer operation is performed by the timer switch 107.

Problems to be Solved by the Invention However, the above-mentioned conventional timer control device is expensive because it is provided with 1. the timer adjustment switch 103 for instructing the start of the timer time setting operation and the timer switch 107 for performing the timer operation. 2. Since the confirmation of the timer setting time and the instruction of the timer operation become independent operations, it is difficult to operate, and 3. When designing the operation panel, the number of operation switches increases and it is difficult to arrange each switch. There were challenges.

The present invention has been made in view of such a point, and by using a timer adjustment switch and a timer switch for instructing the start of a timer time setting operation, the switch is simplified and the timer time is adjusted. The purpose is to improve the usability by connecting a timer operation instruction to a series of operations.

Means for Solving the Problems In order to solve the above problems, the present invention provides a first timer control device, which is a timer started by a timer switch operation and restarted when a time setting switch is operated. If the time setting switch is operated before the timer expires, a signal is output to the time change unit, and if the time is up, a signal is output to the timer operation unit to enter the timer operation state. It was done.

The second timer control device is in a state where the timer time can be set by the first timer switch operation, the operation of the device is stopped by the second timer switch operation, the timer operation state is established, and the third timer switch is operated. The timer operation is canceled when the operation or the first timer switch operation is left for a predetermined time or more.

According to the present invention, with the above configuration, the timer adjustment switch and the timer switch for instructing the start of the timer time setting operation can be unified into one switch.

EXAMPLES Hereinafter, examples in which the present invention is applied to an oil fan heater will be described in the first.
Description will be made based on the drawings. When the operation switch is turned on, the oil fan heater as the device enters the operation state. On the other hand, if the operation switch is turned on and the timer operation is instructed, the combustion fan waits until the set time is reached, and the current time is set to the timer. At the set time, it returns to the operation state and starts combustion. Further, the oil fan heater also has a temperature control function, and displays both the set temperature and the room temperature as a clock display unit.

1 is an operation panel of an oil fan heater, 2 is a numeral display section which always displays either a temperature display or a clock display, and 3 is "hour" at the time of setting the current time and the timer time.
A switch 4 also serves as a set temperature DOWN for setting and temperature setting. A switch 4 also serves as a "minute" setting for adjusting the current time and the timer time and a set temperature UP for temperature setting.
Is a time setting switch for setting the numeric display section 2 to a current time setting mode for setting the current time, and is connected to the changeover switch 14 by a signal S3. In the current time adjustment mode, the time adjustment lamp 5 'is turned on. Reference numeral 6 denotes a timer switch for instructing to perform a timer operation. During the timer operation, a timer lamp 6 'is turned on. 7 is a numeric display 2
Is a switch for selecting whether to display a clock or a temperature, and is input to the display switching unit 9. 8 is an operation switch. 10 is a timer that counts, for example, 5 seconds.
It is started at the same time as being initialized by operating the timer switch 6, and outputs a signal S1 during operation. The signal S1 is a signal for notifying that the mode is the timer time setting mode, and is connected to the changeover switch 15 and the display changeover section 9.
Further, when the switches 3 and 4 are operated during the timer time setting mode, the timer 10 is restarted by the operation signal S4. When the timer 10 times out, the signal connected to the timer operation unit 11
Information is output to S2. Reference numeral 19 denotes a timer time lamp which lights up when the timer time is displayed on the numeral display section 2. Reference numeral 12 denotes a timer time change unit which stores a timer time. Reference numeral 13 denotes a current time change unit which stores the current time. Reference numeral 16 denotes a set temperature change unit which stores a set temperature. Reference numeral 17 denotes a clock display data section, which is either a data of the current time changing section 13 or a data of the timer time changing section 12, and is on standby. Reference numeral 18 denotes a temperature display data section, which is either a data of the set temperature change section 16 or a room temperature (not shown) which is selected and is on standby.
The data of 18 or the data of the clock display data section 17 is output to the numeric display section 2.

First, an operation for adjusting the current time in the above configuration will be described. When the time setting switch 5 is pressed, the time setting lamp 5 'is turned on and the signal S3 is output, and the display switching section 9 switches the number display section 2 and the switches 3 and 4 at the same time as they are connected to the clock side.
Is closed. As a result, the change of “hour” and “minute” by operating the switches 3 and 4 causes the current time change unit 13 to output the signal S4
Is input.

Next, the operation during the timer operation will be described. When the timer switch 6 is pressed, the timer lamp 6 'lights up,
At the same time as the timer 10 is initialized, it is started and the signal S1 is output. When the changeover switch 15 is closed by the output of the signal S1, the display switching unit 9 connects the numeric display unit 2, the switch 3, and the switch 4 to the clock side, so that the numeric display unit 2 displays some timer time. At this time, the timer time lamp 19 is also turned on to indicate that the contents of the number display section 2 are timer times. The user first checks the timer time, and if necessary, operates the switches 3 and 4 to set the desired time. At this time, when the switch 3 or the switch 4 is operated, the signal S4 is also input to the timer 10, so that the timer 10 is restarted.

Next, when the setting of the timer time is completed and five seconds have elapsed, the timer 10 times out, so that the signal S2 is output instead of the signal S1. At this point, the timer lamp 6 'remains on, the timer lamp 19 turns off, and the changeover switch 15
Returning to OFF, the timer operation unit 11 starts. Therefore, the device is stopped (the combustion is stopped in the case of the oil fan heater) until the current time reaches the set timer time.

On the other hand, as a result of pressing the timer switch 6 and confirming the timer time, if the set time has not been changed, the timer 10 times out after 5 seconds and starts the timer operation as described above.

As described above, the setting and confirmation of the timer time and the instruction to start the timer operation can be performed in sequence with only one operation of the timer switch 6, so that the operability is improved and at the same time, the conventional timer time setting switch and timer switch are replaced. The unification can be made, the circuit configuration can be simplified, and the cost can be reduced. At the same time, the total number of switches in the operation panel unit 1 can be reduced, so that the design can be performed easily.

FIG. 2 shows that the set value of the timer 10 is 30
Seconds timer 20, counter 21, switch
22 is an embodiment of a configuration in which the configuration of FIG. The counter 21 counts the number of times the timer switch 6 is operated. The counter 21 sequentially switches from the contact a of the changeover switch 22 to b and c in accordance with the count value of the counter 21, and returns to the contact a after the contact c. The signal S1 is applied to the contact b of the changeover switch 22 and the signal S2
Is connected to the contact c.

When the timer switch 6 is pressed once, the timer time lamp 19 is turned on, the timer 20 is initialized, and at the same time, the contact of the switch 22 is switched to b and the signal S1 is turned on.
Is output. At the same time as the changeover switch 15 is closed by the output of the signal S1, the display switching unit 9 connects the numeral display unit 2 and the switches 3 and 4 to the clock side, so that the numeral display unit 2 displays some timer time. The user first checks the timer time, and if it is necessary to change the timer, operates the switches 3 and 4 to set the desired time. At this time, when the switch 3 or the switch 4 is operated, the timer 20 is restarted.

When the setting of the timer time is completed, the second operation of the timer switch 6 is performed. As a result, a signal S2 is output instead of the contact b of the switch 22.
That is, the user can switch to the timer operation at his own will. At this time, the timer time lamp 19 turns off, the changeover switch 15 returns to OFF, and the timer motion unit 11 starts simultaneously with turning on the timer lamp 6 '. The following operation is the same as that of the previous embodiment. In this embodiment, if the user forgets the operation of holding down the timer switch 6 once, the counter is reset when 30 seconds of the timer 20 expires. The timer 21 is cleared, the contact of the changeover switch 22 is returned to a, the timer time setting mode is released, and the clock function is operated.

As described above, the setting and confirmation of the timer time and the instruction to start the timer operation are performed by one switch, but the user operates the timer switch by himself / herself while confirming each state. This will ensure that you will proceed to the next state.

Effect of the Invention As described above, as is clear from the embodiment, the present invention provides an instruction for adjusting the current time, a "time adjustment switch", and an instruction for setting the timer time, while separately providing each switch such as a "timer switch". The time adjustment between the clock time and the timer time is performed not by using the time adjustment switch or the timer switch but by the setting switch provided independently, so that the current time adjustment and the timer time adjustment can be clearly distinguished from each other. It is possible to maintain uniformity in operation, and at the same time, it is possible to set detailed time, so that the operation is very easy to understand.

Further, the timer switch also gives an instruction to start the timer operation, and is automatically activated after the timer time is set by the operation of the first timer which is started by the operation of the timer switch and restarted by the operation of the time setting switch. In addition, there is an effect that it is possible to simultaneously satisfy the contradictory features of the convenience of entering and the improvement of usability with a small number of operation switches. Further, since the number of operation switches can be eliminated, there is an effect that the circuit configuration is simplified and the cost can be reduced. Further, the second timer control device has an advantage that the operation can be reliably performed because the setting and confirmation of the timer time and the start of the timer operation can be switched at will of the user. In addition, if you accidentally operate the timer switch, you can stop the timer operation by further operating the timer switch, and even if the timer switch is operated unconsciously,
If left for a certain period of time, the timer operation is canceled, so that there is also an effect that there is no fear of erroneous operation.
