DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an abnormality alarm device for dry cleaning equipment.

Conventionally, cleaning equipment such as dry cleaners and washing machines has not been equipped with an abnormality alarm device that automatically warns of an abnormality and stops the machine when an abnormality occurs in the machine. Even if this occurs, the cleaning device continues to operate, and it is not until cleaning is completed that the machine becomes aware of an abnormality, which is problematic in terms of operation and protection and safety of the items to be washed.

The present invention was proposed in view of the above circumstances, and aims to provide an abnormality detection device for dry cleaning equipment that is excellent in safety, operability, and maintainability, and is capable of controlling the operation of dry cleaning equipment. A central control unit, an operation unit that gives operation commands to the central control unit, and a water source, a steam source, an air source, a solvent supply unit, etc. of the dry cleaning equipment are provided to detect abnormal conditions in the respective parts. It is equipped with an anomaly detection switch that inputs this information to the central control section, and a display section that is attached to the operation section and also serves as a time display that displays all the anomaly contents in symbols based on the detection results of the anomaly detection switch. It is characterized by

An embodiment of the present invention will be explained with reference to the drawings.
Figure 1 is a block diagram showing the circuit configuration, Figure 2 is a block diagram showing the circuit configuration.
The figure is a front view showing the operation panel of FIG. 1.

In the above figure, 1 is a cleaning device for dry cleaning laundry items, 2 is an operation panel for operating the cleaning device 1, and 3 is a control device for controlling the operation of the cleaning device 1.

The cleaning device 1 includes an abnormality detection switch for a medium necessary for cleaning, such as a water source abnormality detection switch 11 that detects an abnormality in the water source, a steam source abnormality detection switch 12 that detects an abnormality in the steam source, and an abnormality detection switch 12 that detects an abnormality in the air source. and a solvent amount detection switch 14 that detects the pumping state and drainage state of the solvent in the processing tank (not shown) of the cleaning device. It is designed to be input to a central control device 8, which will be described later.

The operation panel 2 includes a program selection switch 4 that selects eight types of operation programs, a time display 5 that displays the required operation time and the details of the abnormality, and a start switch that controls the operation and stop of the cleaning device 1. In addition to a switch 6 and a stop switch 7, there are also an indicator lamp that displays the cleaning process and the operating method of each process, a process omission switch that omit processes, and a time setter that adjusts the operating time.

The control device 3 includes a central control device 8 consisting of an electronic circuit that forms the control center of the cleaning device 1, an electronic storage device 9 that stores eight types of programs, and a cleaning device 8 that performs cleaning under instructions from the central control device 8. Output circuit 1 that causes device 1 to perform a predetermined operation
0, a buzzer 15 is built in to notify the end of cleaning.

In such a device, the abnormality detection switch 1
When 1 to 14 detect an abnormality, their respective outputs are input to the central control device 8, and the operation panel 2
The time display 5 performs the following display depending on the location where the abnormality is detected. That is, (1) "K1" is displayed when the water source abnormality detection switch 11 is activated for 10 seconds or more, (2) "K2" is displayed when the steam source abnormality detection switch 12 is activated for 10 seconds or more, (3) If the air source abnormality detection switch 13 operates for more than 10 seconds, "3" will be displayed. (4) If the solvent amount detection switch 14 does not operate at the set timing while the cleaning device is operating, the solvent is not pumped properly. (5) If the solvent amount detection switch 14 is still operating at the set timing while the cleaning device is in operation, "KO5" is displayed due to poor solvent drainage.

First, assume that the operator selects operation program No. 5 using the program selection switch 4 of the operation panel 2, for example, as shown in FIG. 2, and then presses the start switch 6.

Then, the output signals of the program selection switch 4 and the start switch 6 are input to the electronic storage device 9 via the central control device 8, and the corresponding information is transmitted from the electronic storage device 9 to the central control device 8, and the operation panel 2 The time required for operation program No. 5 is displayed on the time display 5, and at the same time, the output circuit 10 is activated and the cleaning device 1 starts a predetermined operation.

Next, in the cleaning device 1, the central controller 8 operates the output circuit 10 based on the information output from the electronic storage device 9, and pumps the solvent from the solvent tank (not shown) to the processing tank (not shown).

At that time, if for some reason the pump does not turn, the valve of the solvent tank does not open, the solvent amount detection switch 14 does not operate even after the set time, etc., the cleaning device 1 3
The system immediately stops based on the command from the central control device 8, turns off the required operating time displayed on the time display 5 of the operation panel 2, displays the abnormality display symbol "ko4", and turns on the buzzer 15 intermittently. Activate it to warn that the solvent is not being pumped up.

Then, the operator learned that there was a problem with the solvent pumping.
We will investigate the cause and take appropriate measures, but first, since the buzzer is making too much noise, we will press the stop switch 7 to stop the buzzer and investigate the cause. After determining the cause of the solvent pumping failure and taking appropriate measures, the operator also presses the stop switch 7 once. Then, the display on the time display 5 changes from "4" to the time required for cleaning, and the machine is in a standby state, so the start switch 6 is pressed to start the machine.

During that time, the abnormality display symbol displayed on the time display 5 and the buzzer 15 are activated by the abnormality detection switches 11 to 1.
Even if 4 returns midway, it will not disappear because it is self-preserving. The buzzer 15 is stopped by pressing the first stop switch 7, and after investigating the cause and taking measures, the second stop switch 7 is pressed.
If the abnormality detection switches 11 to 14 have been restored by pressing , the abnormality display symbol will disappear and the required driving time will be displayed, and the system will wait for operation to resume.If the abnormality detection switches 11 to 14 are still operating, It is controlled by the central controller 8 so that the abnormality display symbol continues to be displayed.

When the operation of the cleaning device 1 is restarted, the cleaning process progresses, and the solvent in the treatment tank is returned to the solvent tank, if for some reason the solvent amount detection switch 14 remains activated even after the set time has elapsed. , as in the case of the solvent pumping failure described above, the cleaning device 1 is stopped, "5" is displayed on the time display 5, and the buzzer 15 is activated intermittently.
Since the operator is alerted that the solvent has not been drained, the operator performs the recovery process in the same manner as described above. Similarly, the abnormality detection switches 11 to 14 continue to monitor the cleaning device 1 so that it can operate under the best conditions.

Furthermore, if a plurality of abnormality detection switches 11 to 14 operate simultaneously, for example, if water source abnormality detection switch 11, steam source abnormality detection switch 12, and air source abnormality detection switch 13 operate simultaneously, even if the cleaning device is in operation, If the abnormal condition is compounded, the time display 5 will display "K1", "K2", and "K3" sequentially every second, and the buzzer 15 will operate intermittently. to warn you of this.

Therefore, the operator can investigate the cause and take measures as described above to sequentially erase the abnormality display.

Conventional cam-type controllers and card-type controllers are mechanical controllers, so it is difficult to perform monitoring functions such as abnormality alarms and operation displays. Since operational functions can be added with control, it is possible to prevent damage to laundry items due to machine abnormalities, detect abnormalities early, shorten repair time, etc., and save a lot of money in terms of cleaning equipment maintenance. effective. Abnormality detection switch 11~
In addition to the above-mentioned items, 14 can also include an abnormality detection switch that operates when a thermal relay is activated to prevent motor overload, or when it is not possible to correct vibrations that occur during liquid removal. Furthermore, the abnormal location can be displayed by providing a plurality of indicator lights corresponding to the detected location and lighting up the abnormal location.

In short, according to the present invention, there is provided a central control section that controls the operation of the dry cleaning apparatus, an operation section that gives an operation command to the central control section, a water source section, a steam source section, an air source section of the dry cleaning apparatus, An abnormality detection switch installed in each of the solvent supply parts, etc., detects the abnormal state of each part and inputs it to the central control part, and an abnormality detection switch attached to the operation part detects all abnormalities based on the detection results of the abnormality detection switch. The present invention is industrially extremely useful because it provides an abnormality alarm device for dry cleaning equipment that is excellent in safety, operability, and maintainability by providing a display unit that doubles as a time indicator for displaying symbols. It is.
