The two operation modes (settings 1 to 4) are described.

Among these settings 1 to 4, the feature of the present invention is that the "low" operation is performed during the time of the off timer (T1) of "setting 3", and the time measurement of the on timer (T2) is completed. After that, it is an operation mode for performing "strong" operation. (Refer to the flow chart of FIG. 1) In addition, in "setting 2", a characteristic operating mode that has not existed in the past is obtained. That is, "strong" operation is performed while the off timer (T1) is counting, and the on timer (T1) is
It is an operation mode in which "weak" operation is performed after the time measurement in 2) is completed.

These settings 1 to 4 can be selected according to the preference of the warmer.

Next, the operation will be described mainly based on the flowchart shown in FIG. First, "setting 1" by the operation mode setting means shown in FIG. 5 will be described. This setting is effective when going to bed when the temperature in the room is relatively low and waking up when the temperature in the room is expected to drop significantly the next morning.

After operating the off timer button (49), the feed button (47) is operated to set the energization time to the first and second heaters (7) and (8) and the fan motor (11), The remaining time is displayed on the time display portion (45), and the feed timer (50) is operated after the on timer button (50) is operated to operate the first and second heaters (7),
(8) and the energization start time for the fan motor (11) are set and displayed on the time display section (45). (S1) After the setting of each timer is completed, the on / off timer detection circuit (70) confirms that the timer is set (S2), and after detecting the set of the off timer (T1) (S3), When it is detected that the operation mode is set to "strong", the first and second heaters (7) and (8) are energized to rotate the fan motor (11) at high speed to discharge hot air.
(S4), (S5) This "strong" operation time is measured by the off timer (T1), and the "strong" operation is continued during the time of a predetermined time (remaining time set by the off timer). (S6), (S7) Eventually, when the off timer (T1) finishes counting the predetermined time, the "strong" operation mode is released, and the first and second heaters (7) and (8) and the fan motor (11) are released. Stop energizing to. (S8) After the off timer (T1) has timed, the on / off timer detection circuit (70) sets the on timer (T2) to detect whether or not the timer is continuing (S9), and (S1)
0), counting is performed until the warm air generation start time in the next morning. When the ON timer (T2) finishes measuring a predetermined time and the current time and the set time of the ON timer (T2) match (S11), the "strong" operation mode is set and the first and second heaters (7) are set. , (8) and the fan motor (11) are energized. (S12), (S13) Although not shown in the flowchart of FIG. 1, the heating heater (13) is turned on by the end of the timing of the ON timer (T2) after the “strong” operation stop in step (S8). Electric power is supplied to heat the heat storage body (12) to bring it into a full heat storage state.

Therefore, in the "strong" operation mode at the end of the timing of the ON timer (T2), the hot air generated by the first and second heaters (7) and (8) and the damper control circuit (39) are driven. Accompanying first and second dampers (16),
The air passing through the blower duct (5) due to the rotation of (17) is mixed with the heat of the heat storage body (12) released through the heat radiation path (15) as shown by the arrow in FIG. Discharge from 4).

Next, "setting 2" by the operation mode setting means
Is described. This setting is effective when going to bed when the temperature in the room is relatively low and waking up when it is expected that the temperature in the room will not become too low the next morning.

After operating the off timer (T1),
The energization time to the second heaters (7) and (8) and the fan motor (11) is set and the remaining time is displayed.

When the setting of each timer is completed, the operations of steps (S1) to (S7) are performed in the same manner as the above-mentioned "setting 1", the "strong" operation is continued, and the "strong" operation is performed in step (S8). To stop.

After the timer (T1) is timed, it is detected that the on timer (T2) is set (S
9), (S10), counts up to the hot air generation start time in the next morning, and when the on-timer (T2) finishes counting the predetermined time (S11), determines that the mode is the "weak" operation mode. (S12), the second heater (8) and the fan motor (11) are energized to start the "weak" operation. (S1
4), (S15) "Setting 3" by the operation mode setting means will be described.
This setting is used when the temperature in the room is high, for example, when you sleep with other heating equipment (air conditioner) when it is relatively warm and it is expected that the temperature in the room will be relatively low the next morning. It is effective when sleeping and getting up in a warm room.

After the off timer (T1) is operated, the energization time to the second heater (8) and the fan motor (11) is set and the remaining time is displayed. In "Setting 3", since the "weak" operation mode is set in advance, the step (S
In 4), it is determined that the operation mode is "weak" and the "weak" operation is started. (S16), in the "weak" operation mode, the fan motor (11) is driven by the second fan control circuit (41).
Rotates at low speed, and energizes only the second heater (8) to discharge low temperature air.

The off timer (T1) measures the operation time during the "weak" operation, and the "weak" operation is stopped when a predetermined time has elapsed. (S16), (S17), (S18), (S1
9) After that, the set state of the entrance timer (T2) is detected and counting is performed until the time when hot air is generated in the next morning, and the entrance timer (T2) finishes counting the predetermined time and the current time and the entrance timer (T2) When the set times of) match, the "strong" operation mode is set and the first and second heaters (7) and (8) are energized, and the fan motor (11) is rotated at high speed by the first fan control circuit (40). At the same time, the heat radiation of the heat storage body (12) is mixed and hot air is discharged. (S9) to (S13) "Setting 4" by the operation mode setting means will be described.
This setting is when the temperature in the room is high and you go to bed when it is relatively warm, and when it is expected that the temperature in the room will be relatively high the next morning, you will fall asleep quietly and wake up quietly in the room Sometimes effective.

After the off timer (T1) is operated, the energization time to the second heater (8) and the fan motor (11) is set and the remaining time is displayed. Since the "weak" operation mode has been set in advance in "setting 4", it is determined in step (S4) that it is in the "weak" operation mode as in the case of "setting 2" described above, and "weak" operation is performed. To start. (S
16), in the "weak" operation mode, the fan motor (11) rotates at a low speed to energize only the second heater (8) to discharge low temperature air.

The off timer (T1) measures the operation time during the "weak" operation, and the "weak" operation is stopped when a predetermined time has elapsed. (S16) to (S19), and then the on timer (T
2) Detects the set state and counts up to the hot air generation time, and when the incoming timer (T2) finishes counting the predetermined time and the current time and the set time of the incoming timer (T2) match, "weak" operation In the mode, the second heater (8) and the fan motor (11) are energized to discharge low temperature air.

The detailed setting method of "setting 1" to "setting 4" by the above-mentioned operation mode setting means is such that when the warmer sets "setting 1", the off timer button (T
1) and the feed button (47) or the return button (48) are operated to set the off operation time, and then the manual operation button (55) is operated to set to "strong", followed by the time setting button. (46) and the feed button (47) or return button (48) are operated to set the on-operation time, and then the manual operation button (55) is operated to set to "strong" to complete. The completion procedure of these sets constitutes the operation mode setting means of "setting 1".

The same applies to "setting 2" to "setting 4", and the completion procedure of each set constitutes the operation mode setting means of each "setting". Of course, the operations of "setting 1" to "setting 4" are executed on the panel (44),
For example, a selection button having a name such as “setting 1 button” or “setting 2 button” may be provided.

Further, at the time of "weak" operation after the predetermined time of the ON timer (T2), the heat storage switch (52)
It is also possible to utilize the heat dissipation of the heat storage body (12) by setting the above.

[0042]

As described above, according to the present invention, when the off timer and the on-timer are simultaneously set, "weak" operation is performed while the off-timer is timed, and the on-timer measures the time after a predetermined time after the off-timer is timed. Since it has a driving mode in which it finishes and performs "strong" driving, it becomes "weak" driving at bedtime and can sleep in a quiet state, and can wake up in the warm room the next morning.

Further, when the "ON" timer finishes timing and "strong" operation is performed, the heat quantity of the heating means and the heat radiation of the heat storage body are simultaneously discharged as hot air, so that the next morning at the end of the "ON" timer timing, the temperature becomes high. Since the air is discharged and the warmth spreads in a short time, the heating of the heat storage body is performed before the end of the on-timer timing, so it is necessary to energize the warmer to discharge the warm air at the end of the on-timer timing. Therefore, high-temperature air can be obtained without increasing the rated power consumption of the heating equipment.
