The operation of the above embodiment will be explained below.

First, the operation of the confirmation/setting section 8 will be briefly explained.

If none of the indicator lights 13, 14, and 15 are currently lit, the clock signal from the storage unit 41 is supplied to the display signal generation unit 47 via the determination unit 46, and the clock is displayed on the display unit 2. is being done.

This device uses a 12-hour display, including AM, PM (
(AM/PM) is determined by using the extra segment of the number display 3, and FIG. 1 shows PMll:
30 (11:30 p.m.).

If you want to check the operation start time, operation stop time, or set temperature and room temperature in the memory sections 42 or 43, just press the 4 confirmation/setting keys 10, 11, and 12, and the indicator lights 13, 14, and 15 will turn on. It lights up and each stored data is displayed on the display 2.

To return to the clock display, press the clock confirmation/setting key 2.
As soon as the operation is performed a second time, each indicator light turns off.

On the other hand, in order to adjust the clock signal or each stored data, first operate the confirmation/setting keys 9 to 12 for the first time to display the stored data on the display 2.

In addition, in case of confirmation/setting keys 10 to 12, indicator light 13
15 to 15 will light up.

Next, by operating the adjustment keys 16 and 17, the display data is changed and the colon display 1 or the indicator lights 13 to 15 are made to blink, and by operating the confirmation/setting key a second time, the display data is stored in each memory section 41 to 44. All you have to do is transfer it and store it as the new current time, operation start time, operation stop time, and set temperature.

At this time, the flashing of the colon display 1 or the flashing of the indicator lights 13 to 15 ends, the indicator lights 13 to 15 go out, and the display returns to the clock display regardless of the number n.

In addition, when the power is initially turned on and when the power is restored, the operation stop time (AMI:00) and operation start time CAM in the storage unit 45 are stored.
6:00) The control temperature (26° C.) is stored in the storage unit 42°43.44 as initial data.

Next, the operation of the heat pump type air conditioner and the room temperature control associated with the operations of the operating section 24 and the program operating section 19 will be explained with reference to FIGS. 3 to 6.

During operation, the indicator light 29 lights up to notify that the vehicle is in operation, and the room temperature and set temperature in the storage section 44 are called up to the judgment section 46, and a comparison operation is performed between the two.

As a result, the compressor motor, fan motor, four-way valve, or auxiliary heater is controlled by the control unit 48, and the air conditioner performs cooling/heating or blowing air conditioning operation so that the room temperature is maintained near the set temperature.

The health dream key 27 can be set when the vehicle is stopped or when driving using the operation key 26, and the indicator light 29 can be set by operating the key.
, 30 lights up.

Then, as shown in Figure 3, an operation command is issued from the half-cut section 46. If the stop key 25 is pressed after driving for an arbitrary period of time, a stop command is issued and the indicator lights 29 and 30 go out. .

The difference between driving with the driving key 26 and driving with the driving key 26 during this health dream driving is that, as shown in FIG. As time passes, the set temperature of the storage unit 44 changes to 0.
．． 5 or 1 as the new control temperature for the room temperature, and for example, during cooling (same as during heating), the air speed switching lever 18 is used until the room temperature exceeds the control temperature as shown in FIG. When the compressor motor stops because the room temperature exceeds the control temperature, the judgment unit 4 repeats the weak wind and stop at fL1 minute and 7 minute intervals.
6 is to issue a control command for the fan motor via the control unit 48.

The curve t1 in Figure 4 shows the controlled temperature change during cooling, which increases by 0.5°C every hour and increases by 2°C by 4 hours.
When the set temperature is 25℃, the control temperature is 25℃.
It changes from 27℃ to 27℃.

The curve t2 shows the controlled temperature change during heating, and similarly changes by 1°C, and the controlled temperature after 4 hours becomes 21°C.

Note that the upper limit of the control temperature is determined to be 30° C., similar to the set temperature, and the lower limit is determined to be 20° C., and the control temperature is adjusted within this range.

In this way, when operating the Healthy Dream Key 27, the control temperature is relaxed as time passes depending on the key input force, so that you will not feel cold or uncomfortable when sleeping. In addition, when the compressor motor stops, only air is blown, thereby eliminating the noise window and ensuring that the sensor detects the room temperature.

The fully automatic key 28 can be turned on at any time, and by operating the key 28, the clock signal (current time signal) of the clock section 497) is generated.
is manually transmitted to the discriminator 50 via the gate buffer 51.
In addition, this discrimination section 50 uses the specific operation start time (6:00 AM) and operation stop time (AMI) stored in the storage section 45.
:00), time (PIV18:00), and control temperature (26:00).
℃) is called.

Then, as shown in FIG. 6, the clock signal at the time of key operation is compared with the driving start time and driving stop time before and after the clock signal, and it is determined whether or not to issue a driving command.

That is, as shown in FIG. 6, if the operation time is in the operation permission period after the operation start time and before the operation stop time, the operation command is issued at the same time as the operation is turned on.

At this time, the indicator lights 29, 30, and 31 are all lit.

During this operation, the room temperature and a specific control temperature (26°C) are compared and calculated, and air conditioning or ventilation operation is performed.
Keep the temperature around 6°C.

When a match between the clock signal and the time (PM8: 00) is detected, the fan motor performs intermittent operation with a weak breeze and stops when the room temperature exceeds the control temperature, similar to the operation with the Healthy Dream Key 27. The temperature is adjusted by 0.5°C (when cooling) or 1'C (when heating) every hour from 26°C, and after 4 hours it is adjusted to 28°C or 22°C.
adjusted up to.

When the clock signal coincides with the driving stop time (AMI: 00), the indicator light 29.30 turns off, indicating that the Healthy Dream Driving has ended.

After further time passes, the clock signal changes to the operation start time (AM6).
:00), the indicator light 31 goes out to inform you that the operation using the fully automatic key 28 has ended, the operation key 26 is automatically set, the indicator light 29 lights up, and from then on, normal operation is performed. When the fully automatic key 28 is operated after the operation stop time and before the operation start time, as shown in FIG. 6, 2, when operation is started using the operation key 26, no operation command is issued.

At this time, the indicator lights 30 and 31 were lit by the key operation, but the indicator light 29 was not lit, indicating that fully automatic operation was set.
Informs that no driving command has been issued.

When the clock signal reaches the driving start time, a driving command is issued and the indicator light 29 lights up to notify you of this.

After that, the specific control temperature will be 26 at a specific time (8:00 PM).
Room temperature control is performed based on °C, PM8: 007
1) Until the operation stop time (AMI:00), the above-mentioned health dream driving is carried out.At %AMI:00, a stop command is issued and all indicator lights 29, 30, and 31 are turned off. be done.

In Fig. 6 (e), the fully automatic key 28 is operated at a specific time (PM8).
29.30.3) and is in the operation permitted time period before the power-on operation stop time, and the indicator light is turned off by key operation.
All 1 lights up and the vehicle immediately enters the above-mentioned health dream driving mode.

The subsequent operations are the same as in the case of FIG.

Note that the operation using the fully automatic key 28 can be reset at any time using the stop key 25.

In this way, by operating the fully automatic key 28, which has priority over other keys, no other external operation is required, and it is possible to determine whether or not driving is required at the time of key operation, and to determine whether or not to operate at a specific time (AM6: 00.AM).
Starting and stopping operation once each at I: 00), room temperature control using a specific control temperature at a specific time (8:00 PM), and starting and stopping at a specific time (8:00 PM) at a specific time (AMI: 00) In addition to the power that allowed specific control temperature adjustment and quiet air blowing operation when the compressor motor was stopped in the past, any consumer can now perform predetermined program operation during the day and at night with a simple key operation. This means that room temperature control suitable for sleeping can be obtained.

Note that during operation with this fully automatic key 28, the confirmation/setting keys 10, 11, 12 and adjustment key 16 of the confirmation/setting operation section 8 are pressed.
．． 17 to arbitrarily adjust the operation stop time, operation start time, and set temperature, it is possible to perform fully automatic operation based on the adjusted values of and n, etc. only during this operation.

The adjustment value at this time is the same as the normal setting, in each memory section 42, 4.
I remember it on 3.44.

Then, the next time the fully automatic key 28 is pressed, the specific data in the storage section 45 is called up again by the determination section 46.

As described above, the present invention determines the force required to operate a key (fully automatic key) during a driving permission period between a specific driving start time and driving stop time, and determines whether or not driving is required at the time of key operation. For example, a customer requests that an operation command and a stop command be issued based on the coincidence output of a clock signal after a key operation and a specific operation start time and operation stop time. Manufacturers can specify in advance the operation start and stop times that often occur, and customers can select program control for starting and stopping operations at these times using key operations, making it easier for people who are inexperienced to operate It can be easily operated by people, the elderly, and children.

Also, specify the standard room temperature control temperature during operation before the operation stop time after operating this key, specify the room temperature control temperature at a specific time before the operation stop time, and specify the room temperature control temperature before the operation stop time. By adjusting the room temperature control temperature from time to time, there is no need for complicated room temperature adjustments, and the room temperature can be controlled to be suitable for health while sleeping.
