Description

[Detailed description of the invention]

The present invention enables a person who reads a necessary program out of a plurality of programs stored in a read-only memory (ROM) and executes the program to modify the read program as appropriate. If the execution time of the program becomes longer than necessary as a result of modification, operation is not started and the program is prompted to be modified again. For example, in dry cleaning, there is a most suitable processing time for each process such as washing, dewatering, drying, etc., and a longer process time does not necessarily mean that the product will be cleaner. In other words, if the washing time with the solvent in the washing tub is longer than necessary, there is a risk that the dirt components that have been dissolved in the solvent will re-adhere to the laundry, resulting in the phenomenon of ``reverse contamination,'' and the laundry may become twisted. Moreover, if the deodorizing process is longer than necessary, there is a risk that the fabric will be damaged due to heat, and the fabric may become stiff.Furthermore, if the entire process time is longer than necessary, the fabric will be severely damaged. However, there are disadvantages in that it requires a large amount of solvent and requires unnecessary heating. The present invention allows the time of each stroke to be arbitrarily modified from the preset time, and the total stroke time that changes depending on the revised stroke time is longer than a preset predetermined time (for example, 100 minutes). When it gets old, it is determined that the length of time is longer than necessary and the system does not start operation. To explain based on the following figures, Fig. 1 shows a block diagram when the dry cleaner is controlled by a microcomputer, and 1 is a control unit (CPU) that performs the entire processing of the dry cleaner.
The storage unit 2, the temporary register 3 where data is temporarily stored, the arithmetic unit (ALU) 4 that performs arithmetic and logic operations based on the data in the register, the control unit 5 that issues control signals and timing signals, and the system It consists of address data bus buffers 6 and 7 for transferring addresses and data. 8 is a first read-only memory (first read-only memory) that stores eight types of washing programs at different addresses.
1ROM), 9 is a second read-only memory (2nd ROM) for operating various devices by issuing output signals in response to signals input from operation keys, etc.;
1 A write memory (RAM) 12 that reads and stores a desired washing program from the ROM 8 reads signals from a keyboard 13 (to be described later), and reads signals from a process display device 14, a program display device 15, and a time display device 16 such as light emitting diodes and flashlights. An I/O interface 17 for lighting the light tube is an I/O interface for reading signals from switches 18 such as door switches and vibration switches, and for issuing signals to an external output 19. FIG. 2 shows the keyboard 13, and by pressing the program key 11 and number keys 20 of 1 to 8, a desired program among the eight types of washing programs stored in the first ROM 8 can be selected from the RAM.
Read out at 10. 21 is a manual key used for manual operation without using the washing program; 22;
23 is a start key, and 24 and 25 are modification keys for changing the contents of the washing program read into the RAM 10. Figure 3 is a stroke display device, “From tank 1” 2

This message appears when the solvents from tanks 1, 2, and 3 are put into the washing tub and the light emitters 38, 39, and 40, which are made of diodes, light up during the washing process. ``Filter circulation'' 29 and ``Filter bypass'' 30 indicate whether the solvent is circulating through the filter or bypassing it during washing, and ``To distiller'' 31 indicates whether the solvent is circulating through the filter during washing. "To tank 1" 32 and "To tank 2" 33 indicate whether the distilled solvent returns to tank 1 or tank 2. Displaying whether to return to "Deliquoring" 3
4 indicates that the liquid removal operation is in progress, "spray" 35 indicates that the finishing agent is being sprayed, and "dry" 36 and "deodorization" 37 indicate that the drying process or deodorization process is in progress, respectively. The light emitting bodies 41, . . . correspond to each display character.

9 is provided. FIG. 4 shows a time display device 16 made of a fluorescent tube and a washing program display device 15.
The numbers shown in normally indicate the remaining time of the current stroke, but if you press the start key 23 while driving, the total remaining time until the end of all strokes will be displayed. . Further, numbers 1 to 8 are provided adjacent to the washing program display device 15, respectively, to display during operation which washing program is being read. for example

When the [expression] key is pressed, the washing program display device 15-1 lights up. FIG. 5 shows an example of a washing program read from ROM 8 and written to RAM 10, and b
The execution time of each process is written at address ~h, and a
The total execution time of each process is stored at the address. FIG. 6 shows the present invention in the form of a flowchart, and the following explanation will be based on this flowchart.
First, the contents of address b of the RAM 10 are read to the calculation unit 4, and it is checked whether there is a stroke "from tank 1", and if there is such a stroke, it is checked whether the stroke time is "0" or not. If the contents of the program stored in RAM10 are still read from ROM8, the process time "from tank 1" will not be "0", but if

If you operate [Formula] and the correction key and number keys, the travel time "from tank 1" will become "0".
At this time, "E8" is displayed on the time display device 16 and at the same time an alarm is generated to notify that the operation has been erroneous. If the operation is erroneous, it can be corrected by pressing the correction key again. If it is not "0", the calculation unit 4 adds the total stroke time stored at address a and the stroke time "from tank 1" stored at address b, and the result is 100 When it is more than a minute,
At the same time as "E9" is displayed on the time display device, an alarm is generated to notify that the correction key has been operated incorrectly. If the calculation result is within 100 minutes, then check the process time "from tank 2", and then check the execution time for all processes "from tank 3", "deliquency", "spray", "drying", and "deodorization". , if all within 100 minutes, wait for the start key 23 to be pressed, and when this start key is pressed, the RAM
The programs written in 10 are executed sequentially. If the time has exceeded 100 minutes in any one place, washing will not start even if the start key 23 is pressed. As described above, in the present invention, since the program can be freely modified, it is possible to make changes to the execution program, and if each stroke is erroneously modified to take a longer time than necessary, the operation will not be performed. Therefore, it does not damage the machine, and when used for dry cleaning, there is no damage to the laundry fabric.Furthermore, it does not use a large amount of solvent and does not cause unnecessary heating.It is a program control device using a microcomputer. can be obtained.
