JPS6264610A - Actuating device for on-vehicle air conditioner - Google Patents

Abstract

PURPOSE:To prevent unnecessary displays and actuations by allowing a display to be made, when a switch is actuated while a system is inoperative, for a certain period of time, during which a switch can be newly actuated so as to select an air conditioning mode in an air conditioner equiped with both a momentary switch and a display device. CONSTITUTION:While a system is in an off mode, when any of DEF, REC, and OUT switches is turned on, a computer carries out processing further down from a step 102. That is, when a specified period of time for a timer TOFF is, for example, more than 5sec, a judgement is made that the timer is just for watching the display of actuations allowing input data concerning these switches to be cancelled. Subsequently, the timer TOFF is allowed to start from a zero point permitting both a blower and a compressor to be suspended. Then if the timer TOFF is more than 5 seconds, the display is put off. And if it is less then 5sec, the display is put on. This configuration prevents unnecessary displays and actuations.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an operating device for an air conditioner for an automobile, which includes a momentary switch and a display device and generates an air conditioning mode selection signal for the air conditioner.

[Conventional technology]

In the operating device for an automobile air conditioner, the display device is usually placed in a non-display device when the device is not in use, similar to accessory equipment such as car radios and car stereos.

[Problem that the invention seeks to solve]

For this reason, when the air conditioner is in a stopped state, it is unclear whether the inside/outside air switching member or the blowout mode switching member is in the on state (that is, air conditioning mode) because it is not displayed.

In view of these problems, the present invention provides an operating device for an air conditioner for an automobile that enables appropriate display without unnecessary display and prevents unnecessary operations from being performed. With the goal.

[Means for solving problems]

Therefore, as shown in FIG. 1, the present invention includes a plurality of momentary switches that generate selection signals for selecting one or more air conditioning modes from among a plurality of air conditioning modes, and stores the selection signals generated by these switches. a memory circuit; a display device that visually displays the stored contents of the memory circuit; and a display that causes the display device to operate for a certain period of time when the momentary switch generates a selection signal when the air conditioner is in an inactive state. and a mode control means that allows operation of a movable member that selects an air conditioning mode when the selection signal is newly generated during a time period related to the display operation for a certain period of time. The above characteristics.

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 into the microcomputer.

[Effect]

According to the invention, the selection of the air conditioning mode can take place in connection with the visual display of the display device. Therefore, when the air conditioner is in the inactive state, the display device is usually not in the display state and no new selection of the air conditioning mode is made. However, when the momentary switch is operated even in the non-operating state, the display device is operated for a certain period of time, and a new selection of the air conditioning mode is permitted during this operation.

〔Example〕

The overall configuration diagram is shown in Figure 2. l is S/'W that operates in conjunction with the ignition switch IGS/W;
It is used to detect the ON/OFF state of W. 2 is a constant voltage circuit, and 3 is a control amplifier using a microcomputer. The control amplifier 3 inputs signals from the sensor 6 and the momentary type S/- of the control panel, and selects the air conditioning mode of the air conditioner 5 through the actuator 4. At the same time, the control amplifier 3 inputs signals from the sensor 6 and the momentary type S/- of the control panel, and at the same time selects the air conditioning mode of the air conditioner 5. It sends a signal to notify the switch, air outlet, etc.) and also activates the announcement display installed on the control panel.

The control panel includes "OFF" mode S/W9 to select suction mode, blowout mode and automatic manual of each control, and "FAN" S/W9 to select fan speed.
W 10, a speed Lo (low) ramp 10a, and a speed Hi (high) ramp 10b. 'FAN''S/
Each time W10 is pressed, the speed can be selected from Lo→Hi-+Lo→Hi. Each time you press it again, the RE
C (inside air) - FRS (outside air) - "REC" S/Wll to select REC and suction mode, and lamp Ila to display REC, VENT-B/L-HE each time you press
"OUT" S/W 12 that selects the blowout mode cyclically from AT to VENT, lamps 12a, 12b, 12C that display each mode, and "A/W" that selects ON/OFF of the refrigeration cycle (A/C). C″S/W 13, lamp 13a that indicates its ON status, “DEF” S/W 14 that selects the defroster blowout mode, DEF mode display lamp 14a1, and increases the set room temperature in 0.5°C increments.
Or lower UPS/W, DOWNS/W,
It has a room temperature setting device 7m consisting of a display that digitally displays the set room temperature.

FIG. 3 shows a control program for the control amplifier 3.

In an input routine 101, the computer 3 inputs signals from the sensor group 6 and the operation panel 7, and stores them in its built-in memory (RAM). At this time "REC" S/W
Every time you press 11, the REC flag set in RAM is set or cleared.OUT''S/W 1
Each time you press 2, the VENT flag and B/L flag are set in the RAM.

Set and release the HEAT flags in sequence. For example, VE

When you press , the B/L flag goes up and other VENT, HEAT
The flag disappears. The next time it is pressed, the B/L flag is cleared and only the HEAT flag is set. “DEF”S/m
Each time 14 is pressed, the DEF flag is set and VENT is set.
, B/L, and HEAT flags will be erased. VENT

When any of the HEAT flags is set, the DEF flag disappears.

Step 102 is a steering knob that determines whether or not the mode is OFF, and when it is ND, step 103 calculates the normal air conditioning control (based on the data input in the input routine 101, the necessary blowout temperature, air volume, blowout mode) etc.). At step 104, an operation display is displayed on the panel section. In step 105, a signal to drive each actuator is output based on the value calculated in step 103, and the process returns.

When the OFF mode is selected in step 102, step 10
At step 6, it is determined whether S/- of "DEF", "REC" or "OUT" has been pressed, and if YES, it is determined at step 107 whether the timer TOFF, which will be described later, is 5 seconds or more. 5 seconds. In the above case, in step 108, a new press regarding S/- of "DEF", "REC" or "OUT" is performed to indicate that the user has pressed these S/- to view the operation display. The manually entered data is processed to be canceled.In other words, each S/W
Each time 11, 12, and 14 are pressed, each flag is set, but the flag set is canceled and the previous data remains the same.

For this purpose, in the input routine 101, the S/W 11
．． 12. Alternatively, when the flag is changed by the signal No. 14, processing for storing the flag before the change in another RAM is also performed at the same time.

In the next step 109, an OFF mode display tie is performed, the blower and compressor are stopped, and the opening degree of the A/M damper for blowing out internal and external air is calculated. Step 111 is a step for determining whether or not the timer T OFF is longer than 5 seconds. If ND, the process goes to step 104 and displays the operation. If YES, the operation display is turned off in step 112 and the process goes to step 105.

In addition, in the operation display in step 104, the room temperature may be displayed on the room temperature setting device 7m, or the set room temperature may be allowed to be changed during the time when TOFF≦5 seconds.
