Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating device for an air conditioner for an automobile, which is provided with a momentary switch and a display device to generate an air conditioning mode selection signal for the air conditioner.

[Conventional technology]

Also in the operating device of the air conditioner for automobiles, like the auxiliary equipment such as car radio and car stereo, it is usual to put the display device in the non-display device when the device is not used.

[Problems to be solved by the invention]

Therefore, it is unknown because the inside / outside air switching member and the blowing mode switching member are not displayed in the stopped state of the air conditioner (that is, the air conditioning mode).

In view of such a problem, the present invention provides an operating device for an air conditioner for an automobile, which enables an appropriate display without performing unnecessary display and prevents unnecessary operation. With the goal.

[Means for solving problems]

Therefore, the present invention stores a plurality of momentary switches that generate selection signals for selecting one or more air conditioning modes from a plurality of air conditioning modes as shown in FIG. 1, and the selection signals generated by these switches. A storage circuit, a display device that visually displays the stored contents of the storage circuit, and a display that activates the display device for a certain period of time when the momentary switch generates a selection signal when the air conditioner is inactive. Control means, and mode control means for permitting the operation of the movable member for selecting the air conditioning mode when the selection signal is newly generated during the time period related to the display operation for the fixed time period. Characterize above.

In such a configuration, the display control means and the mode control means may be a microcomputer, and the storage circuit may be a memory built in the microcomputer.

[Action effect]

According to the invention, the selection of the air conditioning mode can be made in relation to the visual display of the display device. Therefore, when the air conditioner is inactive, the display device is not normally in the display state, and a new selection of the air conditioning mode is not made. However, when the momentary switch is operated even in the non-operation state, the display device operates for a certain period of time, and new selection of the air conditioning mode is allowed during this operation.

〔Example〕

The overall configuration diagram is shown in FIG. 1 is an S / W that operates in conjunction with the ignition switch IGS / W.
It is a key to detect the N, OFF state. Reference numeral 2 is a constant voltage circuit, and 3 is a control amplifier using a microcomputer. The control amplifier 3 inputs the signal from the sensor 6 and the momentary type S / W of the control panel,
At the same time that the air conditioning mode of the air conditioner 5 is selectively operated through the actuator 4, a signal for notifying the air conditioning mode at that time (inside / outside air switching, air outlet, etc.) is sent to the control panel 7, and the announcement display provided on the control panel is also used. Activate.

"AUTO" S / W for selecting automatic manual for suction mode, blowing mode and each control on the control panel
8 and "AUTO" mode lamp 8a, air conditioner OF
F (non-operation) mode "OFF" mode S / W 9, fan speed selection "FAN" S / W 10, speed Lo (low) lamp 10a, speed Hi (high) lamp 1
It has 0b. Each time you press "FAN" S / W 10,
The speed can be selected as Lo → Hi → Lo → Hi. Also, every time you press it, REC (inside air) → FRS (outside air) → REC and suction mode are selected. "REC" S / W 1
1 and REC to display REC, "OUT" S / W 12 for cyclically selecting the blowout mode as VENT → B / L → HEAT → VENT each time it is pressed, and lamps 12a and 12b for displaying each mode. , 12c, ON / OFF of refrigeration cycle (A / C) is selected "A /
C "S / W 13, lamp 13a that indicates that it is ON," DEF "S / W 14, DE that selects the defroster blowing mode
F mode display lamp 14a, and UPS / W, DOWNS / which raises or lowers the set room temperature in steps of 0.5 ° C
W, it has a room temperature setting device 7m consisting of a display for digitally displaying the set room temperature.

FIG. 3 shows a control program of the control amplifier 3. In the input routine 101, the computer 3 causes the sensor group 6,
And a signal from the operation panel 7 are input, and the built-in memory (R
AM). At this time, each time "REC" S / W 11 is pressed, the REC flag set in the RAM is set or released. Every time "OUT" S / W 12 is pressed, the VENT flag set in RAM is set. , B / L flag, and HEAT flag are sequentially set and released. For example, when the VENT flag is set, "OUT" S / W
When 12 is pressed, the B / L flag is set and other VENT, HE
The AT flag disappears. The next time the button is pressed, the B / L flag is erased and only the HEAT flag is set. "DEF" S / W
Each time you press 14, the DEF flag is set and VEN
The T, B / L and HEAT flags will be erased. VEN
When any of the T, B / L and HEAT flags is set, the DEF flag disappears.

In step 102, it is a step of determining whether or not it is the OFF mode. In the case of ND, calculation of normal air conditioning control in step 103 (based on the data input by the input routine 101, the required blowout temperature, air volume, blowout mode, etc. Calculate). At step 104, the operation is displayed on the panel. In step 105, a signal for driving each actuator is output based on the value calculated in step 103, and the process returns.

In the OFF mode at step 102, step 10
At 6, it is determined whether any S / W of "DEF", "REC" or "OUT" has been pressed. If YES, at step 107 it is determined whether a timer TOFF described later is 5 seconds or more. If it is more than 5 seconds, it means that the user has pressed these S / W to see the operation display. In step 108, the new S / W of “DEF”, “REC” or “OUT” is newly added. The data that is pressed and input is canceled. That is, each S / W 11,
Each time 12 or 14 is pressed, each flag is set, but that flag is canceled and the previous data is left as it is. Therefore, when changing the flag by the signal of S / W 11, 12, or 14 in the input routine 101, the flag before the change is changed to another RAM.
At the same time, the process of storing in is performed.

In the next step 109, the OFF mode display timer TOF
Start F 0. Step 110 is a step for performing calculation necessary for controlling each air conditioner in the OFF mode,
The blower and the compressor are stopped, and the opening degree of the A / M damper for blowing the inside and outside air is calculated. Step 111 is a step of judging whether or not the timer TOFF is 5 seconds or more.
If D, go to step 104 and display the operation. YE
In the case of S, the operation display is erased in step 112 and the process goes to step 105.

In the operation display of step 104, the room temperature may be displayed by the room temperature setting device 7m, or the set room temperature may be allowed to be changed during the period of TOFF ≦ 5 seconds.
