DETAILED DESCRIPTION OF THE INVENTION The present invention is capable of displaying both the remaining time of the current journey and the remaining time of all the journeys.

To explain based on the figures below, Fig. 1 shows a block diagram when the dry cleaner is controlled by a microcomputer. 1 is a control unit (CPU) that performs the entire processing of the dry cleaner, and the accumulator 2 and data an arithmetic unit (ALU) 4 that performs arithmetic and logical operations on a temporary register 3 that temporarily leaves the data on the basis of the data in the register;
, a control unit 5 that outputs control signals and timing signals;
and address data bus buffers 6 and 7 for transferring addresses and data between systems. 8 is a first read-only memory (IROM) that stores eight types of washing programs at different addresses, and 9 is a memory for operating various devices by issuing output signals in response to signals input from operation keys, etc. Second read-only memory (second ROM)
, 10 is a write memory (RAM) for reading and storing a desired washing program from the IROM 8 by operating a program key 11, which will be described later; 12 is a writing memory (RAM) for reading signals from a keyboard 13, which will be described later;
1/○ interface for lighting the light emitting diodes and fluorescent tubes of the program display device 15 and the time display device 16;
17 is switches such as door switches and vibration switches 18
This is a 1/0 interface for reading signals from the external output 19 and outputting signals to the external output 19.

FIG. 2 shows the keyboard 13, and by pressing the program key 11 and the number keys 20 from 1 to 8, a desired program among the eight types of washing programs stored in the IROM 8 can be selected. put out.

Reference numeral 21 is a manual key used when performing manual laundry operation without using the washing program, 22 is a stop key that stops the operation during operation, 23 is a start key, and 24 and 25 are RAMIO keys.
This is a modification key for changing the contents of the washing program proposed in .

Figure 3 is a process display device, and the indications ``From tank 1'' 26, ``From tank 2'' 27, and ``From tank 3'' 28 indicate that solvent is being poured into the washing tub from tanks 1, 2, and 3, respectively. Light emitter 3 consisting of a diode during washing
8, 39, and 40 light up to indicate that the process is in progress, "filter circulation" 29 and "
"Filter Bypass" 30 indicates whether the solvent is being circulated through the filter or bypassed during washing, and "To Distiller" 31 indicates whether the solvent in the washing tub is being circulated to the distiller after washing. "To tank 1" 32 and "to tank 2" 33 indicate whether the distilled solvent is returned to tank 1 or tank 2. 34 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. It is used to display something, and the luminous bodies 41, 42, 43, 44 correspond to each display character.
, 45, 46, 47, 48, and 49 are provided.

Fig. 4 shows a time display device 16 and a washing program display device 15, which are made of fluorescent tubes.The numbers displayed on the time display device 16 normally indicate the remaining time of the process currently being carried out, but during operation When the start key 23 is pressed, the total time remaining until the entire process is completed is 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 program 1 key is pressed, the washing program display device 15-1 lights up. FIG. 6 is a flowchart showing the operation, and the following description will be made according to this flowchart.

When the power switch is turned on, it is checked to see if it can be restarted.

When operating for the first time, immediately check the program key 11 and number keys 20, program the washing program in the ROM 8 corresponding to the number, and write it to the RAMIO all-stroke writing zone 50 (consisting of addresses A to N). It's crowded. At the same time, the fluorescent tubes with the corresponding numbers on the washing program display device 15 are turned on. For example, if washing program 3 is specified, 3
The fluorescent tubes 15-3 corresponding to are lit. In case of re-operation,
That is, when washing has been done once, as soon as the power is turned on, the fluorescent tube displaying the previous washing program lights up. Next, check the correction keys 24 and 25, and if the key is pressed, the above-mentioned RAMIO all-stroke writing zone 501 Correct the time for each stroke of the read program. For example, if you press the keys from tank 1 to 1-1-3, the time to take the solvent from tank 1 into the washing tub and wash the clothes will be 13 minutes. This is corrected and stored at address A of the entire process writing band 50.

On the other hand, if the correction keys 24 and 25 are not pressed, the RAMI
The light emitters corresponding to each step of the program that was proposed will light up. For example, when setting washing course 3, "From tank 1", "From tank 2", "Filter circulation", "To distiller", "To tank 1", "To tank 2", "Deliminating", "Drying", "
Deodorizing” luminous bodies 38, 39, 41, 43, 44, 45
, 46, 48, and 49 are lit. Next, the calculation unit 4 totals the time required for each process included in the set washing program, writes the result into the program remaining time writing zone 51 of the RAM, and displays it on the time display device 16.
to be displayed. If the user directly presses the manual key 21 without pressing the program key 11, and then presses the correction keys 24, 25 and the numeric key 20, the contents will be written in the remaining stroke time writing zone 52 of RAMIO.

Next, when the start key 23 is pressed, the contents of address A of the program writing zone 50 are first transferred to the remaining stroke time writing zone 52, and the operation of that stroke is started.

When the program key 11 is operated again during driving, the light emitting elements 38, 39 of all the strokes stored in the all-stroke writing band 501 are stored only while this key is pressed.
49 lights up. During operation, the remaining time of the current stroke written in the remaining stroke time storage band 52 is read out to the accumulator 2, and the calculating section 4 calculates the time every second from that time. Calculate the current remaining time,
It is written in the remaining stroke time storage band 52 again.

On the other hand, the time until the end of all programs is read from the program remaining time storage band 51 and subtracted in the same manner, the current remaining time for all programs is calculated, and it is written into the program remaining time storage band 51 again. During operation, the contents of the remaining stroke time storage band 52 are always displayed on the time display section 16 to inform the user how many minutes remain of the currently underway stroke.

Furthermore, when the start key 23 is operated again during driving, the contents of the program remaining time storage band 51 are displayed on the time display section 16, indicating the time until all strokes are completed. The operation continues in this manner, and when the contents of the remaining stroke time storage band 52 become "0", it means that the stroke has ended and the next stroke is started.

An alarm is set to sound if the liquid level in the solvent tank drops abnormally during operation. As described above, in the case where a washing program consisting of a plurality of strokes is executed using a microcomputer, the present invention constantly calculates the remaining time of the stroke currently being carried out in the microcomputer, and Taking advantage of the fact that when the time reaches 0, the machine moves on to the next process, the remaining time of each process is displayed on the time display, so you can see how the washing process is progressing. It gives you a sense of security, and when you press a specific key during operation, the time until the entire washing program is completed changes and is displayed, making it easy to plan for later work, which is very effective in use. It is.

In addition, since the display of the remaining time of the above-mentioned process and the display of the time until the entire washing program is completed are performed by switching between one time display device, there is no need for separate time display devices for each, thus reducing manufacturing costs. can do.
