2, 23, and a display unit 1 including a ventilation lamp 24 that is a warning lamp, a refueling lamp 26, a time extension lamp 25, and the like.
and c.

Next, the operation will be described. First, when the operation switch 2 is turned on, the ignition operation for burning is started, and the operation lamp 2a blinks. When the combustion is started, the operation lamp 2a is turned on. At the time of turning on, the digital display unit 16 displays the set temperature and the room temperature. At this time, as the content display lamp, the temperature display lamp 21 is turned on. The user compares the set temperature with the room temperature and raises or lowers the set temperature with the low temperature switch 6 or the high temperature switch 5, and controls the combustion amount by the microcomputer in conjunction with it to bring the room temperature close to the set temperature.

Next, the display selection switch 20 switches the display contents of the digital display section 16 to the present time display lamp 22, and the present time is set by the hour switch 6 and the minute switch 5. This combined current time will continue until the power outlet is unplugged.

After adjusting the present time, the ignition time is set in order to perform the timer operation in a cold morning. The display content of the digital display unit 16 is changed to the ignition time display lamp 23 by pressing the display selection switch 20, and the hour switch 6 and the minute switch 5 are pressed in the same manner as the current time to set the time to be ignited. When the current time and the ignition time can be set, the timer switch 11 is pressed to set the timer operation, the combustion is stopped, and the timer lamp 18 is turned on. Then, at the ignition time, the heater automatically starts combustion. This ignition time is also stored until the power outlet is unplugged or changed in the same manner as the current time. Therefore, once the ignition time is set, the timer switch 11 is pushed at night to automatically ignite the timer at the same time every morning. When the operation switch 2 is turned off, the current time is automatically displayed, and the current time change and the display selection switch 20 cannot be accepted.

[0006] In Japanese Utility Model Laid-Open No. 3-87051, a battery and a clock IC are provided and a backup function for the current time is provided, and the clock function continues to operate even if the power outlet is unplugged, and the clock is reset when used. The one without the troublesome work of is shown. In this case, if the time is set at the time of factory shipment, the user does not need to set the time again.

[0007]

However, in the conventional air conditioner as described above, the hour switch 6 or the minute switch 5 is erroneously set even if the current time is set from the time of factory shipment or set by the user. If you press or mischief a small child, the time will change, so the time to operate the timer will shift, and it will take time and effort to set the time again, which is not convenient. Although a child lock may be used, in that case, there is a problem in that all switch operations are locked.

The present invention has been made in order to solve the above problems. Even if the child lock is not used, once the current time is set, the data can be erroneously changed. The purpose is to obtain a control device for air conditioning equipment with improved usability.

[0009]

A control device for an air conditioner according to the present invention comprises a clock function and a time setting means for setting the time keeping of this clock function. The time setting means changes the time in a normal operation. It has a lock function that does not operate, and this lock function is released by continuing to operate the time setting means for a predetermined time.

A second aspect of the invention is such that after the lock function is released, the lock function is activated again when the time setting means for the second predetermined time is not operated.

A third aspect of the present invention has a timer driving function that uses the clock function to start driving at a set reserved time, and the time setting means can set both the reserved time and the current time. The lock function is activated only when the current time is set.

According to a fourth aspect of the present invention, there is provided a power source backup function for operating the clock function even when there is no commercial power source, and a power source backup determination means for determining whether the power source backup function is normal or abnormal. When the determination means determines that there is an abnormality, the lock function is disabled.

A fifth aspect of the invention has a time unset determination means for operating the time setting means to determine whether or not the current time has been set. The time unset determination means determines that the time is not set. In this case, the lock function is not activated.

[0014]

Since the time setting means in the present invention has the lock function, the time is not changed unless it is operated for a predetermined time.

In the second invention, if the time setting means is not operated before the second predetermined time elapses after the lock function is released, the lock function operates again, so that the user changes the time. When there is no will, it cannot be changed accidentally.

According to the third aspect of the invention, when the time setting means is operated, the lock function is activated when changing the current time, and continuous operation for a predetermined time is required, but when changing the reserved time, it is normal. You can change it with.

In the fourth aspect of the invention, the current time can be changed by a normal operation when the power supply backup determining means determines that there is an abnormality.

In the fifth aspect, when the time unset determination means determines that the time is not set, the current time can be changed by a normal operation.

【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a circuit block diagram according to an embodiment of the present invention. The heater main body and the operation display unit are the same as those in the conventional example, and therefore the description thereof is omitted here. In the figure,
Reference numeral 27 is a commercial power supply, 28 is a microcomputer power supply unit connected to the commercial power supply 27, 29 is a control microcomputer that operates from the power supply from the microcomputer power supply unit 28, 30 is an output unit that operates the heater, and 1c is a control microcomputer. A display unit for displaying the current time, temperature, operation information, etc. by the output from 29,
1a is an operation switch 2, a minute switch 5, an hour switch 6,
The time extension switch 7, the timer switch 11, the child lock switch 13, and the display selection switch 20 are operation sections, and the hour switch 5 and the minute switch 5 are time setting means. Reference numeral 30 is a battery, and 34 is a control microcomputer 29 when the supply voltage Va to the control microcomputer 29 decreases.
A reset circuit A that outputs a reset output to the control microcomputer 35 is a clock oscillation circuit that creates a clock that serves as a reference for the operation of the control microcomputer 29, and 36 is a battery 33 that operates when there is no commercial power supply 27 and transfers data to and from the control microcomputer 29. Sub-microcomputer 3 connected to enable state, 37 is sub-microcomputer 3
When the supply voltage Vb to 6 drops, the sub-microcomputer 3
The reset circuits B and 38 that output a reset output to 6 are clock oscillation circuits that create a clock that serves as a reference for the operation of the sub-microcomputer 36, and are configured by a crystal oscillator that creates a reference pulse for time counting.

Further, 39 is a resistor for limiting current, and 40, 4
Reference numeral 1 is a diode for preventing current backflow, which is a sub-microcomputer 3
The voltage Vb applied to 6 is supplied from the microcomputer power supply unit 28 through the diode 41 when the commercial power supply 27 is applied, and is supplied from the battery 33 through the resistor 39 and the diode 40 when the commercial power supply 27 is not present. . Further, 42 is connected to the microcomputer power supply unit 28 and is connected to the commercial power supply 2
A power supply pulse generation circuit that creates a power supply pulse synchronized with the frequency of 7 and outputs the power supply pulse to the control microcomputer 29 and the sub-microcomputer 36. Reference numeral 43 is a power supply when the output of the reset circuit A34 is L level and the control microcomputer 29 is in the reset state. It is a diode connected to eliminate the output of the pulse generation circuit 42. Further, 44 is a soft reset means which is a switch for resetting data other than the current time out of the data stored in the sub-microcomputer 36, 45 is its pull-up resistor, and 46 is a power supply on the control microcomputer 29 side. It is a resistor for making the signal Vc and inputting it to the sub-microcomputer 36.

When the battery 33 is attached, the voltage Vb is applied to the sub-microcomputer 36, and the instant reset circuit B37 operates to reset the sub-microcomputer 36 to the initial state. Since there is no commercial power supply 27, the sub-microcomputer 36 shifts to a sleep mode with low current consumption, and suppresses current consumption from the battery 33 as much as possible.
Even in the sleep mode, the clock pulse generated by the clock oscillation circuit 38 including the crystal oscillator is divided and used as a reference pulse for time counting, and clock processing is performed.

Next, when the commercial power supply 27 is applied, a voltage Va is generated in the microcomputer power supply unit 28 and applied to the control microcomputer 29, and the reset circuit A34 which is the reset means of the instantaneous control microcomputer 29 operates to control. Microcomputer 2
9 is initially reset. At the same time the diode 41
A voltage is supplied to the sub-microcomputer 36 through this, and since this voltage is higher than the voltage of the battery 33, the current consumption from the battery 33 is eliminated, and the sub-microcomputer 36 is
Will be activated by the voltage supplied by.

Further, the power supply pulse generation circuit 42 connected to the microcomputer power supply unit 28 creates a zero cross pulse from the commercial power supply 27 and uses this as a power supply pulse for the control microcomputer 29.
To the sub-microcomputer 36. When the sub-microcomputer 36 detects this power supply pulse, it determines that the commercial power supply 27 is turned on, and releases the sleep mode. When the sleep mode is released, the sub-microcomputer 36 can perform data transfer processing and the like and consumes a large amount of current. However, since the current is supplied from the microcomputer power supply unit 28, there is no problem.

Next, the detailed operation will be described with reference to the flowchart of FIG. After resetting, the control microcomputer 29 sets a lock flag that operates as a lock function (step 51), and then reads data, and stores the data stored in the sub-microcomputer 36 necessary for control and the current time data. The data is taken in and the control is started by using this as initial data (step 52).

In the data read operation, the control microcomputer 29 first outputs a data read request output to the sub-microcomputer 36. The sub-microcomputer 36 outputs data when a data read request is issued from the control microcomputer 29, and the control microcomputer 29 reads this data. Next, the control microcomputer 29 performs control processing as a heater (step 5).
3). For example, when information about the set room temperature is given from the operation unit 1b by a switch operation or the like, the combustion amount of the combustor is adjusted by controlling the electromagnetic pump, the combustion motor, etc. connected to the output unit 30. Control to reach room temperature.

When the data desired to be stored in the sub-microcomputer 36, for example, the set room temperature set by the user, the operation pattern, the failure point, or the like is generated during the heating control, the data reading operation is performed. Sub microcomputer 3
The data is written in 6.

In the data write operation, first, the control microcomputer 29 outputs a data write request output to the sub-microcomputer 36. The sub-microcomputer 36 prepares to read data when the data writing request is made. Next, when data is output from the control microcomputer 29, the sub-microcomputer 36 takes in this data and writes it in the memory. The data written in the memory of the sub-microcomputer 36 does not disappear even if the commercial power supply 27 is lost, so that the data can be controlled by using this data the next time.

The sub-microcomputer 36 similarly performs the clock processing even when the commercial power supply 27 is turned on. The control microcomputer 29 also counts the power supply pulse output from the power supply pulse generating circuit 42 based on the read current time data, and performs clock processing. This current time is displayed on the display unit 1c.
It is output to and can be displayed as a clock.

Next, when the hour switch 6 or the minute switch 5 is pressed while the clock is displayed on the display unit 1c (step 54), the time is not changed immediately because the lock flag is set (step 54). Step 55). To change the time, keep pressing the hour switch 6 or the minute switch 5. Then, the timer 1 in the control microcomputer 29
Starts counting (step 56) and timer 1 is set to 3
The loop of steps 54, 55 and 57 is repeated until the second has elapsed. After 3 seconds, the lock flag is reset (step 58) and the time is changed (step 5).
9). If the current time is set once and then the clock is delayed or advanced, or if the clock does not have a power backup function, there is not much need to change it except when the power is first turned on. Therefore, by providing the operation time of 3 seconds, even if the time setting switch of the hour switch 6 or the minute switch 5 is accidentally touched, the current time will not be easily changed. Press and hold for a second. Further, once the lock flag is reset and the lock function is released, normal switch operation is possible, so that when the data of the current time is changed, usability does not deteriorate.

After the lock flag is reset once and the time setting switch is turned off, the state of the lock flag is judged in step 60, and the timer 2 in the control microcomputer 29 starts counting (step 61) for 8 seconds. The loop of steps 54, 60, 61 and 62 is repeated until the time elapses. When the timer 2 has passed 8 seconds, the lock flag is set again (step 63), and even if the time setting switch is operated thereafter, the time will not change unless it is pressed for 3 seconds or more.

As described above, once the time setting switch is accepted, the switch operation is immediately accepted for 8 seconds after the time setting switch is turned off, but when 8 seconds or more have elapsed, the lock function operates again to change the time. Can not.
As a result, even if the time is changed once, the time setting switch is locked again after a while, so that it is possible to prevent the change of the current time even if the time setting switch is pressed by mistake. In addition, the lock function is always activated when the time setting switch does not need to be operated.
If the data is not input continuously for a second, the current time data is not changed, and the device becomes very resistant to noise.

Example 2. Next, in the case of having a timer driving function that starts driving at the set reserved time, it is necessary to set both the current time and the reserved time, and after setting, if the timer switch 11 is pressed, the reserved time is set. It is possible to automatically start driving. in this case,
The current time does not have to be reset every time, but the reserved time needs to be reset by the time setting switch as needed.

FIG. 3 is a flow chart showing the operation at this time. In the figure, when the time setting switch is pressed, if the current time is displayed on the display unit 1c, it is necessary to wait for 3 seconds as in the first embodiment. Jump to
You can change the displayed reservation time instantly. As described above, the lock function is not operated for the reserved time that may be frequently changed, and by doing so, the operability when performing the timer operation is improved.

Example 3. FIG. 4 is a flow chart showing the operation when an abnormality occurs in the power supply backup function.
If the power backup function is provided, the current time data will not be lost even if the outlet is unplugged, so there is no need to set the time again when the outlet is plugged in again.
However, when the battery 33 is exhausted and the power backup function becomes inoperable, it is necessary to reset the current time each time the outlet is plugged in again. In the figure, in step 52, data is read from the sub-microcomputer 36, and in step 65, it is determined whether the read data is normal. For example, when the battery 33 is exhausted, the data of the sub-microcomputer 36 also disappears. Therefore, the data of the current time on the sub-microcomputer 36 side includes the initial set data, and the time is not adjusted. In this case, if the time unset information is transferred from the sub-microcomputer 36, the control microcomputer 29 sets the backup abnormality flag in step 66.
Also, when the data is not transferred or the transferred data is out of the predetermined range, for example, when the data is 25:00 at the time, the backup abnormality flag is set similarly and the transferred data is not taken.

Next, when the time setting switch is pressed in step 54, it is determined in step 67 whether the backup abnormality flag is set. If it is set, the process jumps to step 59 and the time can be changed immediately. If it is not set, the lock function works. Therefore, if the power backup function is operating normally, there is almost no need to change the time, so there is no risk of the lock function operating and accidentally changing the time. Time
Since it is necessary to set the time, the lock function is disabled and the time can be set by normal operation.

Example 4. FIG. 5 shows that the lock function is disabled only when the current time is not set. In the figure, when the commercial power supply 27 is turned on, the lock flag is set, and then the current time unset flag is set in step 68. Next, when the time setting switch is pressed in step 54, it is determined in step 69 whether or not the present time unset flag is set, and if it is set, the process jumps to step 59 to immediately change the time. Become.
If it is not set, the lock function works. Once the time is set, the present time unset flag is reset in step 70, so that the lock function will always operate when the time setting switch is pressed from the next time. Therefore, if the current time is not set, the lock function can be disabled and the time can be set by normal operation.If the current time is set once, the lock function will operate, and even if you touch the time setting switch by mistake, the time will be set. There is no fear of changing.

[0037]

As described above, according to the present invention, the timepiece function and the time setting means for setting the time of the timepiece are eliminated, and the time setting means has the lock function, and the lock function is operated for a predetermined time. Since it is canceled by continuing the operation, the control device for the air conditioner can be obtained without increasing the cost, without accidentally changing the once set current time.

According to the second invention, after the lock function is released,
Since the lock function is activated again when the time setting means is not operated for the second predetermined time, the lock function is always activated when it is not necessary to operate the time setting means, which is convenient for use. In addition, it is effective against electromagnetic noise.

According to the third aspect of the invention, the time setting means can set both the current time and the reserved time for timer operation,
Since the lock function is activated only when the current time is set, it is convenient for timer operation.

According to the fourth aspect of the invention, the power backup function has a power backup function for determining whether the power backup function is normal or not, and the lock function is prevented from operating when it is determined to be abnormal by the determination means. , When the current time needs to be set, it can be done by normal operation, which is convenient.

According to the fifth aspect of the invention, there is provided a time unset judging means for judging whether or not the time setting means is operated to set the present time, and when the judging means judges that the current time is not set, Since the lock function is set not to operate, it is possible to set the current time first by normal operation, and once set, the lock function operates, which is convenient.
