FIG. 3 shows a remaining block circuit of the abnormality display device according to the present invention, and in this circuit, the detection section 71 is replaced with the various switches shown in FIG. 2, namely switches 26, 31,
, Sl, S2, etc., and is connected to the control unit 72. This control section 72 is connected to an abnormality information memory 13, and a display 74 is connected to a read output terminal of this memory 13. The display 74 is provided on the operation panel 52 shown in FIG. 1, and displays various abnormal conditions in the form of codes, for example, serial numbers.

The table below shows the correspondence between abnormal numbers and abnormal conditions.

Information indicating an abnormal state is stored in the memory 73 in the form of an abnormal number shown in the table above, and the control unit 12 determines the abnormal state according to the operating state of the switches of the detection unit 71 and takes appropriate action. The abnormality number is read out from the memory 73 and supplied to the display section 74.

Detection of some abnormal conditions will be described with reference to the flowcharts of FIGS. 4 to 6B.

First, the water supply system will be explained with reference to FIG.

When the start switch is pressed at the start, the control section 72 determines the cleaning mode. In this cleaning mode determination, it is determined whether the mode is chemical liquid discharge mode or manual air supply mode. If it is not in any mode, the operating state of the upper position switch 26a of the water tank 20 is checked, and if this switch 26a is on, the water supply valve 24 is opened. If it is off, the operating state of the middle position switch 26b is checked. When the middle position switch 261) is off, the control unit 7
2 determines that there is a water shortage, opens the water supply valve 24, and stores the abnormality number 01C in the memory 73. When the abnormality number 01C in the memory 13 is input to the display 74, the abnormality number 010 is displayed on the display 74. From this display number 〇IC, it is determined that the content of the abnormal condition is water shortage. In this case, the washer will not be started. If the middle position switch 26b is on, the operating state of the lower position switch 26c is checked. If the lower position switch 26c is off, the control unit 72 determines that there is a water shortage, and stores the abnormality number 02C in the memory 73. In this case as well, the washer will not start. When the lower position switch 26c is on, a series of cleaning steps starts. The above check flow is repeated until the cleaning process is completed, and the amount of water in the water tank 2G is monitored. When cleaning is completed, the washer will stop.

In the flowchart shown in FIG. M5, the amount of water or chemical solution in the storage tank 2 is monitored.

At the start, the supply of water or disinfectant via the nozzle 8 or 9 is started and, for example, a 3-minute timer is started. At this time, the control unit 12 checks the state of the lower position switch S2 of the storage tank 2.

If this switch S2 is off, the state of the upper position switch SO is checked. When the upper position switch So is off, the timer is checked to see if three minutes have elapsed. If 3 minutes have passed, water injection will be stopped. At this time, the control unit 72 determines that there is a water (chemical) leak, and stores an abnormality number 16'C in the memory 73. If the upper position switch SO is on, the injection of water or chemical solution is stopped and the discharge process is started. At this time, the control unit 12 determines that the amount of water or chemical liquid is low,
The abnormality number 04C is stored in the memory 73.

When the lower position switch S2 is on, the injection of water or chemical solution is stopped. At this time, the endoscope leakage point detection process or disinfection process is started. Again, the state of switch S2 is checked; if it is on, the timer is stopped, and if it is in the upper position switch So, it is checked whether the above process has been completed.

If completed, this flow ends.

When the lower position switch S2 is off, it is checked whether the 10 second timer is operating. If the 10 second timer is activated, it is checked whether 10 seconds have elapsed. After 10 seconds have elapsed, the control unit 12 causes the memory 73 to store an abnormality number 14G indicating a drop in water or chemical liquid level (leakage).

If the 10 second timer is inactive, this timer is started and the state of the upper position switch SO is checked. When this upper position switch So is on, water injection is stopped, and the abnormality number 04C is stored in the memory 13 along with drainage processing.

As described above, when an abnormality occurs in the storage tank 2, the abnormality is detected based on the operating state of the switch So, 32, and an abnormality display is performed.

The flowcharts of FIGS. 6A and 6B display abnormal conditions in the disinfection process. If the lower position switch S2 of the cleaning tank, that is, the storage tank 2, is off at the start of chemical injection, the flow moves to the upper position switch check flow in the flowchart of Fig. 5, and if it is on, the operating state of the lower position switch S2 is checked. be done.

If this switch S2 is off, the process moves to the process start flow in the flowchart of FIG.
3 and displayed on the display 74.

In the chemical liquid recovery, the operating state of the lower position switch S2 of the cleaning tank is checked after the chemical liquid collection starts, as shown in FIG. 6B. If the switch is off, the lower position of the chemical solution tank 23 and the operating state of the switch 37b are checked. When this switch 37b is off, an abnormality number 17c indicating a shortage of recovered chemical solution is stored in the memory 73, and the display 1
4 will be displayed.

Although the flowcharts of FIGS. 4 to 6B are explained to display an abnormal condition that occurs singly, there are cases where a plurality of abnormal conditions occur simultaneously. The display of such multiple abnormal states will be explained.

In this case, abnormality detection is performed in the same manner as 70- shown in FIGS. 4 to 6B, and information indicating the detected abnormal state is sequentially stored and held in the memory 73. The memory 73 is provided with a storage area 73a having a plurality of bits bO to b15 arranged in correspondence with abnormal numbers as shown in FIG. 7. When an abnormality occurs, the bits of the abnormal number corresponding to the abnormal state are stored. 1 is written to , and the occurrence of the abnormality is recorded. Next, when displaying an abnormal number, it is determined whether all bit areas 73a in FIG. 7 are O as shown in the flowchart in FIG. 8. If all bits are not O,
That is, if the determination is NO, one bit cy connected to the output end of the bit area 73a is set to O. Next, the abnormal number storage address EN is set to 1, shifted by 1 bit, and then EN is incremented by 1. CV=
It is determined whether the bit is 1 or not, and if it is No, the bit is shifted by 1 bit again. When cy=1, the abnormal number address E at that time
The abnormality number corresponding to N is read out from the memory 73,
It is displayed on the display 74. When a predetermined period of time passes after the abnormal number is displayed, all bits bo to b in the bit area 73a
It is checked whether 15 has been shifted, and if no, it is shifted by 1 bit again and EN is incremented. At this time, if CV does not become 1, it is further shifted by 1 bit. If cy=1, the abnormality number of the updated address is read out and its display number is displayed on the display 13. That is, a new abnormality is displayed on the display 13.

Abnormal numbers corresponding to the bits set to 1 in this manner are sequentially displayed on the display 74. Bit area 73
Returns to the original state of ζ in which all bits of a are shifted, and all the abnormal numbers corresponding to the bits set to 1 are sequentially displayed again. The abnormal location is determined from this abnormality number display, and when the abnormality is resolved, the corresponding bit in the bit area is set.

In FIG. 9, a memory having a stack structure is used, and abnormal states are stored in the order in which they occur. That is, PO indicates the bottom of the stack, P2 indicates the top of the stack, and the abnormality numbers are stored sequentially from PO to P2 according to the occurrence of an abnormality. When displaying the information stored in the stack memory of FIG. 9, it is displayed according to the flowchart of FIG. 10. At the start of display, P1≧P2 is checked. Pl indicates the stack to be displayed. In the initial stage, since P1≧P2, the origin is displayed first. After a predetermined time, Pl is set to PO, and the process returns to check 70- for P1≧P2. At this time, P1≧
Since it is not P2, the stack of Pl, in this case, the abnormal number 020 of the bottom stack PO is read out and displayed. 02
When C is displayed for a predetermined time, Pl is incremented, and P
Return to the check flow for 1≧P2. In this way, the abnormal numbers are displayed repeatedly in sequence, including the origin display.

If a new abnormality occurs while the abnormality number is displayed,
The information is added according to the flowchart in FIG. For example, if P2 and P3 are stacks of additional information, first P3
is addressed to the bottom stack Po. The abnormal number of P3 is compared with the abnormal number of PO, and if the two are not equal, P3 is incremented by one. P3 whose address has been updated is compared with P2. P unless P3≧P2
3 is compared with the abnormal number of the PO's next stack.

In this way, the contents of the recorded stack and the new contents are sequentially compared, and when P3≧P2 is established, a new abnormal number is stored in the stack of P2. After that, P2 is incremented by one. The data of P4 is also stored in the stack memory following a similar flow.

FIG. 12 shows a flowchart for erasing the abnormality number when the abnormality is resolved. At the start of deletion, P3 is addressed to PO. The data to be deleted (abnormal number) of P3 and that of PO are compared,
If the two do not match, the address of P3 is updated. P3
After determining ≧P2, the abnormal number data to be deleted in P3 is compared with the abnormal number data in the next stack of PO. This operation is repeated until the data to be deleted in P3 is found. When a stack that stores data to be deleted is found, the data in the next stack after this stack is P4.
It is retained as. By putting the data in P4 into the stack P3 that stores the data to be deleted, the data to be deleted is deleted and updated to the data in P4. Next, if P3≧P2 is confirmed, if this does not hold, P4=
Return to the flow of P3+1. This is done to fill up the deleted stack. When P3≧P2 is satisfied, P2 is decremented and the deletion flow ends.

In the above embodiment, the abnormality number is displayed for 0.5 seconds at intervals of 0.5 seconds, but the abnormality lamp may be turned on during the non-display period between displays.

[Effects] According to the present invention, an abnormal situation is displayed using information representing the content of the abnormal state, so countermeasures against the abnormality can be taken quickly.Furthermore, when multiple abnormal situations occur, all the abnormal contents are displayed, so multiple abnormal situations can be displayed. The abnormal location can be identified at once, making it convenient to prepare for repair. Furthermore, since a plurality of abnormal conditions can be known in the order in which they occur, it becomes easier to formulate a repair plan. Since the symbol C is added to the abnormality display along with the number, the display can be easily distinguished from other displays, such as a time display.
