Abstract

PURPOSE:To shorten the time spent by changing the set value of room temperature by detecting a jump instruction of room temperature by a single switching operation and then generating a control signal which changes it to a new value jumped by several steps. CONSTITUTION:There is provided a control circuit 3 which changes the set value to another value jumped by several steps when detecting a jump instruction. Namely, if an UP switch which is a means 7m of setting room temperature is depressed over 2sec, the set value of room temperature is set to be a maximum temperatue of 32 deg.C, for example, and if the switch is depressed for less than 2sec, the set value is set up by 1 deg.C. On the other hand, if a DOWN switch is depressed over 2sec, the set value is set to be a minimum temperature of 18 deg.C, for example, and if it is depressed for less than 2sec, the set value is set down by 1 deg.C. Each control member 5 is controlled via a group of actuators 4 to have the room temperature rise up or down according to the signals detected by a group of various sensors 6 and the other signal selectedly generated by the switches on a control panel 7. If the set value is required to be greatly changed to a newly set value, it may be obtained within a shorter expenditure of time for the changing because of the ability of jumping at a stride.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an air conditioner control device that sets room temperature using a setting means such as a control panel.

Conventionally, the control panel of an air conditioner generally has an UP switch for increasing the set temperature, a DOWN switch for lowering the set temperature, and a display section for displaying the current set temperature. Both the UP switch and the DOWN switch are structured so that the set temperature can only be updated in 1°C increments, so it is difficult to change the set temperature significantly.
You have to press the P switch or DOWN switch many times. For example, if the temperature is initially set at 25°C and you want to raise it to 32°C, you have to press the UP switch seven times. Then UP switch or DO
There is also a way to add a repeat function that changes the set temperature continuously by holding down the WN switch, but if the cycle of this repeat function is 1℃/second, the temperature will change from 18℃ to 32℃, for example. It takes a long time of 14 seconds.

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, the present invention aims to provide an air conditioner control device that shortens the time required to update a set value of indoor temperature.

FIG. 4 is a schematic configuration diagram for clearly demonstrating the present invention. That is, when the detection means 31 detects a jump instruction given by the setting means 70, the control means 32 sends a control signal to update the set value of the indoor temperature to a value that is several steps ahead from the position before the jump instruction was detected. It is to emanate.

An embodiment of the present invention shown in the drawings will be described below.

In FIG. 1, reference numeral 1 denotes a switch that operates in conjunction with an engine key switch and opens and closes a power supply path from an on-vehicle battery BATT to a control circuit 3. At this time, power is supplied via the constant voltage circuit 2.

The control circuit 3 that constitutes the detection means and the control means is composed of a digital computer called a microcomputer, and inputs signals from the various sensor groups 6 and the control panel 7 according to a preset control program, and controls the blower motor through the actuator group 4. , the suction port switching damper, the outlet switching damper, and the adjustment members 5 of the refrigeration compressor. In addition, a signal is sent to the control panel 7, which is a setting means, to notify the status of the adjustment members such as the suction and blowout modes at that time, and the control panel 7
Activate the lamp group installed in the.

This computer 3 preferably has a timer/counter function for timekeeping.

The control panel 7 is provided with a group of switches attached to the group of lamps. This switch group has suction,
AUTOUP to select automatic control of blowout and each control
OFF switch 7b that stops the operation of the Switchia A device;
Lo switch 7c that operates with the air flow fixed at Lo (low)
, Hi switch 7d that fixes the intake mode to outside air, FRS switch that fixes the intake mode to outside air 76% REC that fixes it to inside air
Switch 7f, A/C switch 7g that selects dehumidifying room temperature control, ECONOMY switch 7h that selects power-saving room temperature control, B/L switch 7L that fixes the air outlet mode to VENT, ENT switch 71%, which fixes it at high level. The HEAT switch 7 is fixed, the DEF switch 71 is fixed to the defroster outlet, and the set temperature is 1°C.
UP switch and DOW to raise or lower in increments
A room temperature setting device 7m consisting of an N switch and a display that digitally displays the set room temperature is included.

The above switch consists of a self-resetting pushbutton switch, and AUTO, 0FFSL.

The Hi switches 7a to 7d are in a set and operate only in one of the modes, and only one of the switch lamps lights up in a mode other than the OFF mode.

Also, in the OFF mode, all lamps and set room temperature indicators do not light up. Similarly, the FRS switch, REC switch, A/C switch, ECONOMY switch, and V
ENT.

Each switch of B/LSHEATSDEF is arranged in a set, and only one switch lamp in each set is lit when the switch is not in the OFF mode.

In the above configuration, the present invention will be explained with reference to the operation flowcharts of FIGS. 2 and 3. This device is constantly supplied with power from the battery BATT, and the control circuit 3 when connected to the power source starts arithmetic processing according to the control program shown in FIG. First, in step 100, initial setting prepares for processing and prepares to accept data reading. Then, in step 101, signals from the switches selected on the control panel 7 and signals from various sensors 6 are input. Next step 102
Then, the process moves to a setting change routine whose details are shown in FIG. Here, it is determined whether the UP switch or DOWN switch of the room temperature setting device 7m has been pressed. If the UP switch is pressed, it is determined whether the UP switch was pressed for 2 seconds or more. And U
If the P switch is pressed for 2 seconds or more, the room temperature setting is set to the maximum temperature of 32°C. Also, if the UP switch is pressed for less than 2 seconds, the set value is increased by 1°C. Similarly, if the DOWN switch is pressed for more than 2 seconds, the set value is set to the lowest temperature of 18°C, and if it is less than 2 seconds, the set value is set 1°C lower. In addition, the UP switch, OW
If the N switch is not pressed either, processing continues with the initial setting values.

Then, in accordance with the detection signals of the various sensor groups 6 read in step 101 and the signals selected by the control panel 7, the blower motor is activated via the actuator group 4 so that the room temperature reaches the set value in steps 103 to 108.
Controls each adjustment member 5 of the suction port switching damper, the outlet switching damper, and the refrigeration compressor.

When trying to update the set value of the room temperature in this way, even if the difference from the initial set value is large, it is possible to jump over large amounts at once, so the time required is short. For example, if the initial set value is 26°C and you want to change the setting to the lowest temperature of 18°C, you only need to press the DOWN switch for at least 2 seconds. Compared to previous versions, settings can now be changed in an extremely short amount of time, and the number of times the switch must be pressed is drastically reduced, eliminating the hassle of having to press the switch over and over again.

Other embodiments of the present invention include the following.

In the above embodiment, the UP switch or DOWN switch is
If you press it for a second, the highest temperature will go to the lowest temperature all at once, but you can also set an intermediate point or jump at regular intervals of 5 degrees Celsius.

Also, depending on how long the switch was held down, it was judged whether it was a 1°C increment or a jump, but the UP switch and DOWN switch
In addition to the switch, a jump switch may be provided, and when the jump switch is used at the same time as the UP switch and the DOWN switch, the switch will jump. Furthermore, in addition to the UP and DOWN switches, a jump UP switch and a jump DOWM switch may be used. It may be provided.

When a jump switch is provided in this way, a jump is not determined based on whether the switch is held down for at least a certain period of time, so the time required to change settings can be further shortened.

Also, without installing a jump switch, the UP switch and DOWN switch can each have two-stage contacts.
For a shallow one-step contact point, the temperature may be changed in 1°C increments, and for a deep two-step contact point, it may be changed by a jump. With this configuration, the time required to change settings can be further reduced.

Further, when the minimum and maximum temperatures of 18° C. and 32° C. are set, the capacity of the device may be set to maximum cooling and maximum heating.

As described above, according to the present invention, when a skip instruction is detected from the operation of the setting means, the set value of the room temperature is updated to a position that is several steps higher than the setting value before the skip instruction was detected. This has the excellent effect of shortening the time required to change the room temperature setting and simplifying the operation.
