BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner such as a warm air heater or a room air conditioner having an operation display section including an operation switch and a display.

[0002]

2. Description of the Related Art FIG. 7 is a perspective view showing an example of a conventional hot air heater, and FIG. 8 is a plan view showing an operation display unit. As shown in the figure, an operation display unit 1a including an operation switch for inputting conditions and the like for controlling the operation of the hot air heater main body 1 and an indicator thereof is disposed on the upper surface of the main body 1, and the configuration thereof is as follows. An operation switch 2 for turning on and off the operation of the hot air heater main body 1, a display selection switch 20 for appropriately switching between a digitally displayed temperature display, a current time display, and a timer ignition time display, respectively, and a temperature for each display. Time / low temperature switch 6, minute / high temperature switch 5 for raising or lowering the hour or minute, time extension switch 7 for canceling the function of automatically extinguishing the fire in 3 hours after the start of combustion, and continuing combustion, An operation unit 1b including a child lock switch 13 for preventing an operation other than a driving off even if a child mischiefs, an operation lamp 2a for displaying an operation state, and a digital Le display unit 16, the content display lamp 21,22,2 showing the contents of the digital display 16
3, a display unit 1c including a ventilation lamp 24 as a warning lamp, a refueling lamp 26, and the like.

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

Next, the display content of the digital display section 16 is switched to a current time display lamp 22 by a display selection switch 20, and the current time is adjusted by an “hour” switch 6 and a “minute” switch 5. At the same time, the current time operates until the power outlet is unplugged.

After the current time is set, an ignition time is set to perform a timer operation in a cold morning or the like. The display content of the digital display 16 is changed to an ignition time display lamp 23 by pressing the display selection switch 20, and the time to fire is set by pressing the "hour" switch 6 and the "minute" switch 5 in the same manner as the current time. When the "timer" switch 11 is pressed after the current time and the ignition time have been set, the timer operation is set, the combustion is stopped, and the timer lamp 18 is turned on. Then, when the ignition time comes, the heater automatically starts burning. This ignition time is also stored until the power outlet is unplugged or changed, similarly to the current time. Therefore, once the ignition time is set, simply pressing the "timer" switch 11 at night causes the timer to automatically ignite at the same time every morning. . When the operation switch 2 is set to “OFF”, the current time is automatically displayed, and the change of the current time and the “display selection” switch 20 are not accepted.

[0006]

Since the operation display section 1a of the conventional hot air heater is configured as described above, the display of the temperature and the time is easily confused. Further, when changing the current time, it is necessary to turn the operation switch 2 “ON”, which is inconvenient. At the same time, if the operation switch 2 is “ON”, the current time and the There is a problem that an erroneous operation that changes the ignition time is apt to be performed.

The present invention has been made in order to solve the above-mentioned problems, and the present time can be changed without turning on the operation switch without causing confusion in the display of temperature and time. It is another object of the present invention to provide an air conditioner having an operation display unit in which the current time and the ignition time are not easily changed due to an erroneous operation.

[0008]

In order to achieve the above object, the present invention provides an operation switch and an indicator for inputting conditions for controlling the operation of the air conditioner main body to the air conditioner main body. An operation display unit including a digital display unit commonly used for temperature display and clock display is provided in the operation display unit, and the operation display unit covers part or all of the operation switch and the display. An openable / closable lid and display switching means for switching the display content of the display unit in conjunction with opening and closing of the lid are provided. When the lid is closed, one display is displayed, and when the lid is open, the other display is displayed. When the operation switch is off, the digital display unit displays a clock regardless of whether the lid is opened or closed. In which it was only possible in an open state.

In FIG. 6, reference numeral 27 denotes a commercial power supply, 28 denotes a microcomputer power supply unit, 29 denotes a control microcomputer, 30 denotes an output unit, 31 denotes an input unit, and 32 denotes operation information, temperature, time, and the like based on an output from the control microcomputer 29. And a reset circuit A for outputting a reset output to the control microcomputer 29 when the supply voltage Va to the control microcomputer 29 decreases.
, 35 are clock oscillation circuits for generating a clock which is a reference for the operation of the control microcomputer 29, and 36 is operated by the battery 33 when there is no commercial power supply 27.
Sub-microcomputer connected to enable data transfer with
Reference numeral 7 denotes a reset circuit B for outputting a reset output to the sub-microcomputer 36 when the supply voltage Vb to the sub-microcomputer 36 decreases. Reference numeral 38 denotes a clock oscillation circuit for generating a clock used as a reference for the operation of the sub-microcomputer 36. It is composed of a quartz oscillator for producing a reference pulse for counting.

Reference numeral 39 denotes a current control resistor;
Reference numeral 1 denotes a diode for preventing current from flowing backward.
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 supplied from the battery 33 through the resistor 39 and the diode 40 when there is no commercial power supply 27. Also,
Reference numeral 42 is connected to the microcomputer power supply unit 28, and generates a power pulse synchronized with the frequency of the commercial power supply 27 to control the microcomputer 29.
And a power pulse generating circuit for outputting to the sub-microcomputer 36,
Reference numeral 3 denotes a diode connected to eliminate the output of the power pulse generation circuit 42 when the output of the reset circuit A34 is at the L level and the control microcomputer 29 is in the reset state. 44 is a soft reset means which is a switch for resetting data other than the current time among the data stored in the sub-microcomputer 36, 45 is its pull-up resistor, and 46 is a power supply for the control microcomputer 29. This is a resistor for inputting to the sub-microcomputer 36 as the signal Vc.

With the circuit configuration as described above, when the battery 33 is attached, the voltage Vb is applied to the sub-microcomputer 36, the instant reset circuit B37 operates, and the sub-microcomputer 36 is initially reset. 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.
Also in this sleep mode, the clock pulse generated by the clock oscillation circuit 38 constituted by the crystal oscillator is frequency-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 section 28 and applied to the control microcomputer 29, and the reset circuit A34 as reset means of the instantaneous control microcomputer 29 is operated and controlled. Microcomputer 2

Is supplied to the sub-microcomputer 36, and this voltage is higher than the voltage of the battery 33, so that current consumption from the battery 33 is eliminated and the sub-microcomputer 36
Will operate with the voltage supplied by the switch.

The power supply pulse generating circuit 42 connected to the microcomputer power supply unit 28 generates a zero cross pulse from the commercial power supply 27 and uses this as a power supply pulse to control the microcomputer 2.
9 and the sub-microcomputer 36. Upon detecting this power pulse, the sub-microcomputer 36 determines that the commercial power supply 27 has been 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.

After resetting, the control microcomputer 28 starts reading data, takes in data necessary for control and data of the current time stored in the sub-microcomputer 36 into a memory, and starts control as initial data. .

In the data reading operation, first, the control microcomputer 29 issues a data reading request output to the sub-microcomputer 36. The sub-microcomputer 36 outputs data when there is a data read request from the control microcomputer 29, and outputs data to the control microcomputer 2.
9 reads this data. Next, the control microcomputer 29 performs control processing as a heater. For example, when information on the set room temperature is given by a switch operation or the like from the input unit 31, by controlling an electromagnetic pump, a combustion motor, and the like connected to the output unit 30, the combustion amount of the combustor is adjusted and It is controlled so that it becomes room temperature.

During the heater control, when data to be stored in the sub-microcomputer 36, for example, data such as a set room temperature, an operation pattern, or a failure location set by a user, data reading is performed. The data is written to the sub microcomputer 36.

In the data write operation, first, a data write request output is issued from the control microcomputer 29 to the sub-microcomputer 36. Upon receiving the data write request, the sub-microcomputer 36 prepares for data reading. Next, when data is output from the control microcomputer 29, the sub-microcomputer 36 takes in the data and writes it in the memory. Sub microcomputer 36
The data written in the memory will not be lost even if the commercial power supply 27 is lost, so the next time you use it,
You can control using this data.

The sub-microcomputer 36 also performs clock processing when the commercial power supply 27 is turned off. Also, the control microcomputer 29 counts the power supply pulse output from the power supply pulse generation circuit 42 based on the data of the current time read and performs clock processing. The current time is displayed on the display unit 32
And can perform clock processing.

Next, the operation of this embodiment will be described. When the operation switch 2 is turned on, the operation lamp 2a flashes and the ignition operation for burning starts. At this point, lid 3
Is closed, the digital display section 16 displays the temperature, and the temperature display can be seen from the transparent window section 4 of the lid 3. The display of "set temperature" 3c and "room temperature" 3d are printed above the see-through window 4, so that it is possible to see what the two two-digit digital display sections 16 are displaying, and see through. The clock lamp 17 and the timer lamp 18 visible from the window 4 are turned off.

When the combustion starts, the operation lamp 2a changes to lighting. By comparing the set temperature display with the room temperature display, pressing the "+" key 5 or the "-" key 6 for the room temperature setting raises or lowers the set temperature display, and in conjunction therewith, the control microcomputer 29 reduces the combustion amount. Control so that the room temperature approaches the set temperature. The reason why the temperature is displayed when the lid 3 is closed is that the rib 3b of the lid 3 is turned on by pressing the head of the display changeover switch 8. When the lid 3 is opened, the display changeover switch 8 is turned on. Is turned off, and the digital display 16 displays the time. Therefore, when the user wants to set the current time, the user opens the lid 3 and changes the digital display 16 automatically switched to the clock display by pressing the time setting "hour" key 9 and the time setting "minute" key 10. At this time, the clock lamp 17 is turned on when the lid 3 is opened.

Next, when setting the ignition time to perform the timer operation, the operation switch 2 is turned on and the lid 3 is turned on.
Is opened, first, the "timer set" key 11 is pressed. Then, the combustion is stopped, the timer lamp 18 is turned on, and the digital display section 16 displays the ignition time.
Then, the "hour" key 9 and the "minute" key 10 of the time setting are pressed to set the ignition time display to a desired time. And
At the ignition time, the heater automatically starts burning.
When the lid 3 is closed with the timer set, the digital display 16 displays the temperature, and the set temperature can be changed. To release the timer set, open lid 3 and
When the timer "cancel" key 12 is pressed, the digital display 1
6 changes to the current time and combustion can be started.

When the operation switch 2 is turned off, the lid 3
The current time is displayed whether the is opened or closed. This current time display cannot be changed when the lid 3 is closed.
, And only by pressing the "hour" key 9 and the "minute" key 10 for time setting. Even if switch 2 is on,
The time can be changed even with "Off".

The head of the display changeover switch 8 protrudes from the upper surface of the seat 14. This is because even if the cover 3 is not present, the display is not performed in order to prevent the temperature from being set when the cover 3 is closed when the cover 3 comes off for some reason and is lost or damaged. If the head of the changeover switch 8 is pressed with a finger, the display is switched to a temperature display and the set temperature can be changed.

In the above-described embodiment, an example in which the clock is displayed when the lid 3 is opened and the temperature is displayed when the lid 3 is closed is described. However, the temperature may be displayed when the lid 3 is opened and the clock may be displayed when the lid 3 is closed. .
