Abstract

PURPOSE: To improve operability by stopping the operation of an equipment, stopping the timing operation of a coin timer and performing an abnormality notification when an abnormality is generated during an operation. CONSTITUTION: When the temperature within a drum warehouse is abnormally heated, an abnormality detection part 9 is operated, a signal is transmitted to an operation control part 8 and the operation control part 8 discriminates the signal of the abnormality detection part 9. When the abnormality is decided, the signals turning off semiconductor switches 6 and 7 are outputted and the heat source 5 of a motor 4 is stopped and a timer motor 3 is also stopped. An abnormality notification part 10 blows a buzzer and notifies the state of the abnormality by a display. Thus, operability can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a coin-operated clothes dryer that operates for a certain period of time by inserting a coin.

2. Description of the Related Art A conventional coin-operated clothes dryer has a structure as shown in FIG. In FIG. 2, reference numeral 1 denotes a commercial power supply, which is connected to a semiconductor switch 6, 7 through a coin timer 2 having a timer motor 3, and a motor 4 that rotates a drum that is a drying chamber and a fan that blows hot air to the drum, and a heat source 5. Power is supplied via. Reference numeral 8 denotes an operation control unit, which outputs a signal to turn on the semiconductor switch 6.7 during normal operation, and when the abnormality detection unit 9 is activated, sets the semiconductor switch 6.7 to 0) F, and controls the motor 4 and the heat source 6. Stop power supply.

Problems to be Solved by the Invention In such a conventional configuration, if the abnormality detection unit 9 is activated due to abnormal heating in the drum, the motor 4 and the heat source 6 are stopped, but the timer motor 3 of the coin timer 2 is Since power is supplied to the timer, the timer advances, and after a certain period of time, the coin timer 2 turns off, and the operation ends without drying the clothes. The problem was that it was not clear.

The present invention solves the above-mentioned problems, and provides a coin-operated clothes dryer that, when stopped due to an abnormality, notifies the user and also turns off the timer of the coin timer to stop the timer. With the goal.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a heat source for heating the drum, a motor for rotating the drum and circulating hot air and driving the fan, and a motor for rotating the heat source and the motor. an operation control unit for driving, a coin timer for supplying power to the heat source and the motor by inserting a coin and stopping the power supply after a certain period of time, and an abnormality detection means for detecting an abnormality during operation, the operation control unit If an abnormality is detected by the abnormality detection means, the power supply to the heat source and the motor is stopped, the timing operation of the coin timer is stopped, and the abnormality is notified by the notification means.

Function: With this configuration, if an abnormality occurs during operation, the equipment is stopped, the coin timer's timing operation is stopped, and an abnormality notification is issued.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG. In FIG. 1, parts that are the same as those in the conventional configuration are given the same reference numerals, and their explanations will be omitted. In the present embodiment, the operation control section 8 detects the υ abnormality through the abnormality detection section 9 and issues an abnormality notification through the notification section 10, for example, in the event of an abnormality such as abnormal heating inside the drum. Reference numeral 11 denotes an abnormality release switch, which is a switch for restarting the operation.

In the above configuration, when a coin is inserted, the contact of the coin timer 2 is turned ON and power is supplied to the operation control section 8. Next, the operation control unit 8 turns on the semiconductor switch 6.7.
A signal is output, and power is supplied to the motor 4 and heat source 6 to start operation. The timer motor 3 is connected in parallel with the motor 4, and when the motor 4 is operating, the timer motor 3 also operates, and when the motor 4 is not operating, the timer motor 3 also does not operate. During operation, for example, if the filter installed inside the drum becomes clogged with clothing lint and the temperature inside the drum becomes abnormally high, or if the belt of the fan that circulates hot air breaks, When the temperature becomes abnormally high, the abnormality detection section 9 is activated and sends a signal to the operation control section 8. The operation control section 8 discriminates the signal from the abnormality detection section 9, and when it is determined that there is an abnormality, outputs a signal to turn off the semiconductor switch 6.7, and stops the motor 4 and heat source 5. At this time, the timer motor 3 also stops. Further, the abnormality notification unit 1° notifies the abnormal state by sounding a buzzer and by displaying a display. Next, for example, when the filter is clogged, by operating the abnormality release switch 11 after cleaning the filter,
The abnormality alarm state is canceled, power is supplied to the motor 4 and heat source 6 again, operation resumes, and the coin timer 2
also starts timing operation.

Further, the timer motor 3 of the coin timer 2 can be controlled directly by the operation control section 8 via a semiconductor switch.

Effects of the Invention As is clear from the embodiments described above, according to the present invention, when an abnormality occurs in the equipment, the operation is stopped, the timekeeping operation of the coin timer is also stopped, and the abnormal state is notified. By continuing to notify the user of the abnormality, the user can be informed of the abnormality, and once the abnormality is resolved, the system can be operated again, improving usability.
