Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timer operating device for an electric appliance used for heating a petroleum hot air heater or the like, which burns fuel and uses the combustion heat for heating. 2. Description of the Related Art In recent years, home heaters and the like have been improved in various ways, such as those that burn fuel, mix this with indoor air with a blower, and heat it as warm air, due to increased awareness of ease of use and comfort. It has been done. For example, as shown in FIG. 3, in a conventional inexpensive combustion device having no time setting and time display functions, the operation switch 11 and the timer setting unit 13 are turned on in order to start operation at a preset time. The elapsed time until the start of operation is set in the timer time adjustment unit 14, and the time reduction timer counter unit 15
The count is subtracted from the set time. When the value becomes zero, a signal is output from the timer comparison unit 16 and a signal S2 for starting operation is sent to the combustion unit 12. However, in this combustion device, the operation switch 11 and the timer setting unit 13 are turned off.
Then, the value of the decrement timer counter 15 is cleared, so that the timer must be reset again by the timer adjusting unit 14 in order to operate the timer again. Further, when the set time has elapsed and the combustion control unit 12 has instructed the operation, the value of the decrement timer counter 15 remains zero, so that the next time the timer operation of the combustion appliance is performed, The set time must be reset by the timer time adjustment unit 14. Therefore, even when driving at a fixed time every day, it is necessary to set the time every time, so that there is a problem that it takes time and effort for the user and the setting error easily occurs. SUMMARY OF THE INVENTION An object of the present invention is to solve the drawbacks of the conventional example and to make it possible to easily set the time for timer operation with a simple and inexpensive configuration. Means for Solving the Problems In order to achieve the above object, the present invention provides a device without a time setting and time display function, a timer set section for starting operation at a preset time, and a process for starting the operation. 24 hours as soon as the power is turned on, regardless of the ON / OFF status of the operation switch and timer setting section, and the timer time setting section that sets the time.
The timer starts counting when the initial value is set, and outputs a signal to the timer setting section when the count value reaches a certain value.The timer counter section changes the set time with the timer time adjustment section A configuration in which 24 hours are counted repeatedly until a certain value is output. Alternatively, the timer time adjustment unit is configured to set a time at which a switch such as a power switch or a reset switch of the electric appliance is turned on as a first set time. Operation The present invention is a device having no time setting and time display functions according to the above-described configuration. When the device is operated at a predetermined time every day, once it is adjusted once, it is only necessary to turn on the timer set unit from then on. Since the initial value of 24 hours is also set by turning on the power, it is not necessary to set the time in the timer time adjusting unit. When the time setting is changed, it is set by the timer time adjustment unit, so that the count is subtracted from the set time, and when a certain value is reached, 24 hours are set again and the countdown is repeated. . Furthermore, the time can be set only by turning on the power supply or the reset switch at the above-mentioned fixed time,
The time setting work can be omitted, the operation setting time can be set accurately, and the operation can be simplified, and a simple and inexpensive configuration can be achieved. Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings, using an example adopted in a combustion apparatus. In FIG. 1, a combustion device includes a temperature setting unit 1, a temperature control unit 2, a combustion control unit 3,
It comprises a fuel adjusting section 4 and an air amount adjusting section 5. Then, the combustion control unit 3 starts combustion in accordance with a predetermined sequence according to a signal from the operation switch 6 and the timer setting unit 7 at the time of the timer operation, and sets the temperature (set temperature) set by the temperature setting unit 1. The combustion controller 4 and the air amount controller 5 are controlled based on the output from the temperature controller 2 that outputs an output corresponding to the difference from the room temperature, and the combustion is controlled, for example, to be strong, weak, or OFF. In addition, the combustion device without the time setting and time display functions has a timer setting unit 7 for starting combustion at a preset time.
And a timer time adjusting unit 8 for setting an elapsed time up to the combustion start time, and counting down the set time or the initial value of 24 hours set at the same time when the power is turned on. A timer counter unit 9 which determines by the comparison unit 10 and outputs a signal to the timer setting unit 7, for example, a timer counter unit for reducing the time, is provided. The timer switch unit 9 includes an operation switch 6 and a timer setting unit 7.
Irrespective of ON and OFF, the count is subtracted from the set time, and when it becomes zero , 24 hours are set again and the countdown is repeated. Referring to the flowchart of FIG. 2, when the power of the electric appliance is turned on, an initial value of 24 hours is set in the time-out timer counter 9 and the counting is started. Until the set time is changed by the timer time adjusting unit 8, the value of the time-out timer counter unit 9 is counted down. Then, when the value of the timer counter unit 9 becomes zero , the signal S1 is sent to the combustion control unit 3 when the timer setting unit 7 is ON, and the combustion starts when the operation switch 6 is ON. Is done. Further the value of the reduced time the timer counter 9 is less than zero, is set again reduced at between timer <br/> over counter unit value of 9 for 24 hours, so as to repeat the count down. Therefore, the signal S1 sent to the combustion control unit 3, the time when the turn of the electrical appliance when not changing the setting time, and if you change the set time 24 hour cycle time was the set That is, it is output every day. Therefore, once the time is set, the timer operation can be performed at the same time every day just by turning on the timer setting unit 7, and there is no need to reset the time in the timer time adjusting unit 8. Also, the change of the set time may be set by setting a difference between the target time and the time before the setting. For example, if the timer operation is to be started one hour earlier than the previous day, the value of the timer counter unit 9 at that time is calculated. A value obtained by subtracting one hour is sufficient, which is very simple. Further, the value of the reduced time the timer counter unit 9 at the time of the power on or reset switch is set to 24 hours, starts counting. Thus, if the power supply or the reset switch is turned on at the time of the day before the timer operation is to be started, the time can be set easily and accurately. Note that the above embodiment is shown as an example of the present invention, and it is needless to say that the present invention is not limited to the configuration of the embodiment and may have any configuration as long as the objects and effects of the present invention are achieved. That is. Effects of the Invention As described above, according to the present invention, even an inexpensive electric appliance having no time setting and time display functions can be operated for 24 hours without turning on the time by the timer time adjusting unit just by turning on the power. it is possible to set the initial value, it is possible to timer operation at the same time every day simply by turning oN the timer setting section. When the set time is changed by the timer setting unit, the timer counts down in a 24-hour cycle based on the set time. Becomes Since apply time of the power or a reset switch is a timer operation start time, it becomes possible to easily and inexpensively configured with a timer operation can be set accurately also easy.
