Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a device that automatically operates according to a program stored in a microcomputer, and is capable of changing the program even during operation without pressing the stop key. It is.

Generally speaking, in a vehicle that operates according to a program set on a microcomputer, it is necessary to press the stop key to stop the program before the program is restarted, in order to prevent the program from being changed if the keyboard is accidentally touched during operation. Many things cannot be changed.

The present invention is designed so that the program kK can be changed even during operation except for a specific operation course, which is particularly convenient when it is necessary to adjust the drying time sound as appropriate while monitoring the drying condition, such as in a clothes dryer. Also, it is possible to change the program only by pressing the function keys and number keys, and if the interval between key operations is longer than a predetermined time, it will accept manual input from that point onwards. Is there a way to make it difficult for the program to be changed if a key is touched by mistake? In order to achieve this objective, the next number key signal will be accepted only within a certain period of time after the function key signal is input, and
When the number key signal has multiple digits, the next number key signal is accepted only within a certain period of time after the previous number key signal is input, and subsequent inputs are rejected. Due to this, the program is almost never changed except when a key is operated intentionally.

To explain based on the diagram below, (1) is a clothes dryer with a clothes loading door (2) on the front, and above this door there is a main switch (3) for turning on and off the power, and an automatic detection Dryness adjustment knob (4) for adjusting the degree of dryness at the end;

The input to the CPUC5υ includes 06 bits from the D/A converter 4M device that outputs the inlet temperature, outlet temperature, and dryness adjustment knob (4) settings, as well as the operating course, time and temperature settings, and Keyboard switch for start/stop operation, course preset switch to select and set the driving course when power is turned on, 4 hits from ■, 50Hz/60H2 specification changeover switch, door switch, and thermal switch■ 6 bits from , 1 bit from the reset circuit 2 for resetting η, and 1 bit from the reset circuit 2 for resetting η at 9 when the power supply is turned on, and a rectangular wave voltage of the power supply frequency are all generated and sent to the external interrupt terminal of the CPU C; J). There is one pin from the external interrupt circuit that is input. In addition, the output of CPU II) is to the fluorescent display tube (61) for displaying time, etc., to the fluorescent display tube (7) for displaying temperature, etc., and to the fluorescent display tube (7) for displaying temperature, etc. to the D/A converter for reading the setting value of the temperature control knob), and the steam valve (161Ql/live steam valve (2

In this flowchart, the function key refers to all the keys on the keyboard 151 except a certain number key (1), and the program number key refers to the automatic detection key (A) or the time collateral Φ-(B). This refers to the number key you press, and the general number key refers to the automatic detection key f.
A) Time system subkey + B) Stop key (, r) and Start key (number keys pressed after non-phantom function keys).

When the power supply circuit breaker (3) is checked, check whether the function key and the number key are operated manually. If the prisoner presses the automatic detection key (A) or the time system (wealth) key now, the 1 program number key wait flag will be raised.

In this state, by pressing the number keys 1 to 4, a desired course out of the four driving courses is set, and then by pressing the start key (K) and L, driving is started.

If you want to manually assemble any program 2 and run it according to that program, do the following: For example, if you want to specify the entire hot air time, press the manual key (C) and the hot air time key. When the hot air time key is pressed, the general number key wait 1 flag is set, and when the general number key is pressed, the signal f CP' is stored in address 6 of RAM in U (,31). Specify Wharf 1 where I want to perform drying operation for 65 minutes: HE@-Hide! ]-1N
Press -11. In this case, there is no particular limit I/'i on the operation interval time of each key. After this, after setting the temperature etc., press the start key (KITh) and the operation will start.

If you want to change the hot air time while checking the dryness of clothes while driving, press the hot air time key (g) and number key (I).
? push. When you press the hot air time key [Smell], the operating flag is on at this time, and this operation is not in the live steam input process, nor is it in cold air operation, nor is it in the automatic detection course, so the 'General number key wait 1' button is pressed. After setting the flag and preparing to store it in the next number key QRAM address 6, clear the changeable time force/kunta. When you press the number key (1) on the arrow, the value is stored in address 6 of the RAM, but there is an interval of more than 5 seconds between pressing the hot air key (no meeting) and pressing the number key (I)'t-. Otherwise, the turtle general number key wait q flag will be deleted, so all number keys will not be accepted.Also, when entering multiple digits of hot air time, even if the first number key is entered within 5 seconds, the number key will not be accepted. Since the changeable time counter is all cleared each time a key is input, pressing the next number key after 5 seconds will not be accepted.Please note that the automatic detection key (Nl or timetable 1 key (B) If all driving courses are specified, no keystrokes will occur while driving unless the stop key (, y) is pressed.

When operating by specifying the hot air time, etc. as described above, you can freely change the operation details even during operation.For example, in the case of a clothes dryer, you can extend the operating time at any time while monitoring the drying condition. By shortening the V and making it easier to use as you get older, it is necessary to press both the function key and the number key to make changes, and if the key operation interval exceeds a certain time, all key signals will not be accepted. ,
Even if you accidentally touch the keyboard, the contents of the microcomputer's memory are unlikely to be changed.
