Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a petroleum fan heater,
The present invention relates to a timer operation control device such as an FF warm air heater.

[0002]

2. Description of the Related Art Generally, a combustor such as an oil fan heater or an FF warm air heater is equipped with a timer operation control device. If a desired time is set and a timer key is pressed, the combustion is performed at the desired time. To start. As shown in FIG. 6, in the conventional setting method, the timer setting key 1 is first pressed to switch to the timer time setting mode, and thereafter, −, +
Set the desired time using the time setting keys 2 and 3 of
The timer setting key 1 was pressed to release the timer time setting mode, and then the timer key 4 was pressed to start the timer operation.

[0003]

However, in the above-mentioned conventional configuration, after the timer setting key 1 is pressed in the initial state where the timer time is not set, the desired time is set by pressing the time setting keys 2 and 3. , It is necessary to press the timer key 4, and it is necessary to operate two keys other than the time setting keys 2 and 3 for setting the timer time to start the timer operation, that is, the timer setting key 1 and the timer key 4, which is complicated. Operation was required.

Further, since the signal is received at the same time when the timer key 4 is operated and the timer operation state is entered, if the timer key 4 is erroneously pressed during the time setting, the combustion immediately starts. There was also a problem that it was not easy to use, such as stopping and entering the timer operation state and not accepting reset.

Further, such a timer operation control device is provided with a clock display section 5. However, even if the timer time has already been set on the clock display section 5, it is only necessary to press the timer key 4. Since the set timer time is not displayed and the user has to press the timer setting key 1 in order to confirm it, there is a problem in that it is inconvenient from this point of view.

[0006] Of the above problems, the present invention is intended to realize easy setting of timer operation and improve usability.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 11 denotes an operation unit of the apparatus main body,
Reference numeral 12 is an operation switch provided in the operation unit 11, 13 is a timer key for instructing a timer operation, 14 and 15 are time setting keys (hereinafter referred to as − / + keys) for setting a timer operation time, and 16 is a timepiece. In this embodiment, the display unit is configured to display the timer time together with the current time.

Reference numeral 17 denotes a central control unit (microcomputer) which operates based on the input data of each of the keys 13 to 15 and issues a control command for timer setting and operation. Reference numeral 18 denotes a timekeeping unit, which is activated by an output from the central control unit 17 which is issued based on the operation of the timer key 13 or the − / + keys 14 and 15, and performs a counting operation and outputs a count-up signal after a predetermined time. It is designed to output to 17. The timekeeping unit 18 has a 30-second timer that is activated when the timer key 13 is operated, as will be described later.
It consists of a 5-second timer that is activated by the operation of the + keys 14 and 15, and measures different times depending on the key operation. Reference numeral 19 is a second timekeeping section which is similarly operated by the output from the central control section 17.

Reference numeral 20 denotes a load which operates in response to a signal from the central control unit 17, and is a fuel supply means for supplying fuel to the burner, a combustion air supply means for supplying combustion air to the burner, and a blower for warm air. It comprises a hot air supply means such as a fan for performing. Reference numeral 21 is an informing means for emitting an informing sound based on the output of the central control unit 17.

The operation of the above arrangement will be described below. First, press the operation switch 12 to start the combustion operation, and then press the timer key 13 to enter the timer setting mode. If the timer time has already been set, the display unit 1
6 shows the timer operation time. At the same time, the timer of the clock unit 18 is started,
・ If the + key 14 or 15 is not operated, a beeping sound is emitted after 5 seconds and combustion is automatically stopped, and the timer waiting change mode (stops combustion and waits for timer operation. The time is displayed).

At this time, that is, when the timer key 13 is pressed to enter the timer setting mode, the timer time is not set, and the timekeeping is canceled if 30 seconds elapse without the operation of the-/ + keys 14 and 15. ,-+ Key 14,
If there is an operation of 15, the timer time is changed. Then, the change of the timer time is completed, and the- ・ + key 1
When the operations of 4 and 15 are lost, a beeping sound is emitted after 5 seconds, combustion is automatically stopped, and the timer waiting change mode is set.

In this timer waiting change mode, the combustion is stopped and the timer is in a waiting state. However, the second timer 19 operates after the timer waiting change mode is entered, and the timer counts 5 seconds. Until that time, that is, within 10 seconds after the operation of the − / + keys 14 and 15 is completed, the timer time can be reset if the − / + keys 14 and 15 are operated again. After that, 5 seconds after the operation of the-/ + keys 14 and 15 is stopped, the timer waiting current time display mode is automatically displayed (the current time is displayed on the display unit 16 while the combustion is stopped in the timer operation waiting state). Therefore, changes in the timer operation time will not be accepted.

When the current time reaches the set time for the timer operation, the timer combustion is started by the output from the central controller 17.

The details of the operation will be described below with reference to the flow charts of FIGS.

In step 4, the timer operation is accepted, and in step S5, the timer setting mode is accepted. In step S6, it is determined whether or not the current time is set. If the current time is set, the process proceeds to step S7. If not, the process proceeds to step S10 to cancel the timer operation. In step S7, it is determined whether or not the timer time is set, and if it is set, the process proceeds to step S8 to start counting of the 5-second timer of the timer unit 18, and if not set, the process proceeds to step S9 and the timer unit 18 is started. The counting of the 30 second timer is started, and the process proceeds to the timer setting mode process of FIG.

Next, in the timer setting mode process of FIG. 3, it is determined in step S11 whether the operation switch 12 is pressed. If the operation switch 12 is pressed, the process proceeds to step S12. S17
Go to and cancel the timer operation. In step S12, it is determined whether or not the timer key 13 is pressed. When the timer key 13 is pressed, the process proceeds to step 17 to cancel the timer operation. If not pressed, step S13
Proceed to. In step S13, the time setting-/ + key 1
It is determined whether or not 4 and 15 are pressed. If they are pressed, the process proceeds to step S14 to accept the timer change mode. If it has not been pressed, the process proceeds to step S15 and the timekeeping unit 1
It is determined whether or not the timer of 8 is counting up, and if it is counting up, the process proceeds to step S16,
If it is not counted up, the process returns to step S11.
In step S16, it is determined whether or not the timer time is already set. If the timer time is set, the process proceeds to step S18 to accept the timer waiting change mode, and if not set, the process proceeds to step S17 to cancel the timer operation.

FIG. 4 shows the timer changing mode process, in which the timer time changing process in step S13 is performed.
Since the + keys 14 and 15 have been operated, the change of the timer time is accepted in step S21, and the counting of the 5-second timer of the clock unit 17 is started again in step S22. In step S23, it is determined whether the operation switch 12 is pressed. If the operation switch 12 is pressed, the process proceeds to step S24. If not, the process proceeds to step S30 to cancel the timer operation. Step S24
Then, it is determined whether or not the timer key 13 is pressed. When the timer key 13 is pressed, the process proceeds to step S30 to cancel the timer operation. If not pressed, step S2
Go to 5. In step S25, it is determined whether or not the time setting − / + keys 14 and 15 have been pressed. If they are pressed, the process returns to step S21 to change the timer time, and if they are not pressed, the process proceeds to step S26. Step S2
At 6, it is judged whether or not the timer of the timekeeping section 18 has counted up. If the timer has not counted up, the procedure returns to step S23, and if it has counted up, the step S2

On the other hand, FIG. 5 shows a timer waiting change mode process. Here, first, in step S31, the second timer 1
The 5-second timer 9 is started, and it is determined in step S32 whether the operation switch 12 is pressed. If the operation switch 12 is pressed, the process proceeds to step S33.
If it has not been pressed, the process proceeds to step S38 to cancel the timer operation. In step S33, it is determined whether or not the timer key 13 is pressed. When the timer key 13 is pressed, the process proceeds to step S38 to cancel the timer operation. If not pressed, the process proceeds to step S34. Step S34
Then, it is determined whether or not the time-setting +/- keys 14 and 15 have been pressed. If they have been pressed, the process proceeds to step S35, the timer time is changed, and the process returns to step S31. If not, the process proceeds to step S36. . In step S36, it is determined whether or not the timer of the second clock unit 19 is counting up. If the timer is counting up, the process proceeds to step S37, and if it is not counting up, the process returns to step S32. In step S37, the timer waiting current time mode is accepted, and when this mode is entered, the display unit 16 returns to the current time display, and the subsequent − / + key 1 is pressed.
The change of the timer time by 4 and 15 is not accepted, and the timer burning is started at a predetermined time.

The processing is carried out according to the above flow. Among these, the lengths of the timers of the timer section 18 and the second timer section 19 may be set to an appropriate time according to the actual feeling of use, and the notification means 21 may be used. The notification sound may be different from the normal reception sound and may be a different sound as long as the user can surely determine that the timer operation has started.

Further, in order to make it easy to judge during these modes, the display part may be changed to a blinking display in a certain mode, or may be changed to a blinking display in the initial state or when no setting is made.

[0024]
