Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pay switch control device used in electrical equipment such as an electric washing machine, in which a user inserts a predetermined coin to connect a power source to a load for a certain period of time. At the same time, if the total time of power connection to the load exceeds a certain time, a lamp etc. will be used to notify that the specified time has elapsed, and after a certain period of time has elapsed after the announcement, the system will prevent the insertion of coins and energize the load. The present invention relates to a toll switch control device that prevents such charges from occurring.

Traditionally, paid switch control devices used in electrical equipment are
It only had the function of connecting a power source to a load for a certain period of time by inserting a coin, and did not have a function of determining the total usage time of the electrical equipment that was the load.

For this reason, the product may be used beyond its lifespan, or it may not be possible to know when it is time to replace mechanically worn parts, resulting in inconveniences in terms of service and maintenance.

The present invention eliminates the above-mentioned drawbacks, and within a certain period of time,
When a coin is inserted, the load is energized, but if the total usage time of the load exceeds a certain amount of time, a notification light will be turned on to notify that it is time for service, and while the notification continues, the load can continue to operate for a certain period of time. However, after that, the load is not energized by, for example, preventing the insertion of coins.

FIG. 1 shows a block diagram of the operation of one embodiment of the present invention.

In FIG. 1, when a predetermined coin is inserted, a short-time timer operates and the load power source is energized for 60 minutes, and at the same time, the integrated long-term timer is also energized in reverse for 60 minutes.

This operation is repeated every time a predetermined number of coins are inserted, and the energizing time is added up to the cumulative long-time timer for each operation.

Here, as an example of the setting time of the integrated long-time timer,
If two types, 4,800 hours and 5,000 hours, are set, a series of operations can be repeated if the total operating time is less than 4,800 hours, and operation is possible between 4,800 and 5,000 hours, but the notification light cannot be displayed. Do it in parallel.

Further, when the total time exceeds 5,000 hours, the next operation cannot be started by blocking coin insertion or the like.

FIG. 2 shows an electrical circuit diagram of one embodiment of the present invention.

In Figure 2, 1 is a relay to remember that a coin has been inserted, 2 is a short-time timer that regulates the energization time to the load, 3 is a load such as a washing machine, and 4 is an integrating type length for a notification light. Time timer, 5 is an integrated long time timer for preventing coin insertion, 6 is a notification light, 7 is a solenoid for preventing coin insertion, 8 is a normally open contact for the coin insertion detection switch, 9 is a reset button attached to the short timer 2 Normally closed contacts, 10 and 11 are the normally open contacts of the relay 1, 12 and 13 are the normally open contacts of the short time timer 2, 14 is the normally open contact of the integrated long time timer 4 for the notification light, and 15 is the short time contact. The normally closed contact of the timer 2 and 16 are the normally closed contacts of an integrating type long timer for preventing coin insertion.

Next, the basic operation of one embodiment of the present invention will be explained.

Now, when a coin is inserted, the normally open contact 8 of the detection switch is closed and the relay 1 is energized, and the normally open contact 10 is closed and the relay 1 is self-held.

Also, at this time, the timer 2 is energized for a short time by the normally open contact 11, and starts operating.The timer 2 is self-maintained by the normally open contact 12, and the washing machine is energized for a certain period of time. This is integrated into the two long-term timers 4 and 5.

In this way, washing is started and timers 4 and 5 are integrated.

In this way, washing is started and the washing machine is energized for a certain period of time set by timer 2, but just before the end of washing, normally closed contact 9 for reset opens and relay 1 returns to the timing state, and then timer 2 is turned on for a short time. The contacts 12 and 13 return to their original positions and the timer operation ends, and at the same time, the power to the long timers 4 and 5 is also cut off.

During the washing operation, the normally closed contact 15 opens and the solenoid 7
In this way, the washing time is accumulated in the long time timers 4 and 5 in sequence.

When the total accumulated time exceeds the value set in the long-term timer 4 for notification lights (4,800 hours in the example), the contact 14 of the long-time timer 4 closes, lights up the notification light 6, and performs maintenance (or ) indicates that the time is near.

While the notification light 6 is on, conventional washing operations are possible, but when the total accumulated time eventually reaches the value set in the long-term timer 5 (5000 hours in the example), the long-term timer 5 is permanently closed. The contact point 16 opens and prevents the solenoid 7 from being energized, preventing coins from being accepted, and from then on the washing machine and the like are no longer energized.

The paid switch control device of the present invention grasps the total usage time of electrical equipment that serves as a load, notifies the user when a predetermined time (life span or maintenance period) is approaching, and also notifies the user when a predetermined time exceeds the notice period. When the battery reaches the end of its lifespan, it automatically becomes unusable, preventing unreasonable usage beyond its lifespan, and has the excellent effect of preventing disasters.
