Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garment pressing machine for wrinkling and creasing garments and the like.

2. Description of the Related Art Conventionally, this type of clothes press has a structure as shown in FIG. That is, the power source 1 was connected to the contact 20 of the timer 19, the heater 2, the thermostat 3, and the temperature fuse 4 connected in series. Then, by turning the timer 19, the contact 20 is closed for a certain period of time, the energization control of the heater 2 is performed while controlling the temperature by the thermostat 3, and after a certain period of time, the contact 20 is automatically opened to cut off the circuit of the heater 2. It is structured like this.

However, in the above-described conventional configuration, when the timer 19 or its contact 20 is short-circuited and the heater circuit is constantly energized, only the temperature control is performed unless the thermostat 3 is short-circuited at the same time, and the temperature fuse 4 is connected. There is a problem that the heater circuit cannot be cut off without being cut off.

Therefore, the first object of the present invention is to detect the above-mentioned abnormality and reliably shut off the heater circuit.

A second object is to provide a safe and kind clothing press that can inform the user of the above abnormality immediately.

Means for Solving the Problems In order to achieve the above first object, the present invention provides a pair of press plates for heating clothes and the like by sandwiching a heater on at least one side, and a temperature for controlling the temperature of the press plates. A control means, a first timer device that manually starts energization of the heater circuit and starts timekeeping, and shuts off the heater circuit after a predetermined time, and power is supplied by energization of the heater circuit to measure time. It is provided with a second timer device which starts and shuts off the heater circuit after a predetermined time.

Further, in order to achieve the second object, the present invention is provided with an abnormality notifying means which operates when the second timer device measures a predetermined time.

With the above configuration, the present invention operates the second timer device even if the first timer device fails during use, so that the heater circuit can be reliably cut off after a predetermined time. . In addition, the abnormality notification means
Will be able to inform you of the failure of the timer device.

EXAMPLES Examples of the present invention will be described below with reference to the drawings.

FIG. 1 shows the structure of the clothes press according to the first embodiment of the present invention. In the figure, reference numeral 1 is a power source, which is connected to a heater circuit including a heater 2, a thermostat 3 for controlling the temperature of the heater 2, and a temperature fuse 4. Reference numeral 5 is a first timer device, which comprises a DC power source 6, a relay 7 for turning ON / OFF the heater 2, a transistor 8 for driving the relay 7, and a timer 9 for starting a timed operation by a switch 10. Reference numeral 11 is a second timer device which starts a timed operation by turning on the relay 7.

Next, the operation of the configuration of this embodiment will be described. Port A of this timer 9 is Low when not in operation, Hig during timed operation
If it is h, pressing the switch 10 causes the timer 9 to start timed operation, the port A becomes High, the transistor 8 is turned on, and the relay 7 is turned on for a predetermined time. Next, when the relay 7 is turned on, the second timer device 11 automatically operates for a time period to bring the port A to High. After a predetermined time, the port A of the timer 9 becomes Low, and the relay 7 is turned off, so that the second timer device 1
1 is also reset. However, when the relay 7 does not turn off after a predetermined time elapses due to some failure of the first timer device 5, the second timer device 11 becomes a predetermined time or more, so the port of the second timer device 11 A is Hi
become gh.

As described above, since the port A of the second timer device 11 is High during the timed operation of the timer 9, the transistor 12 is turned on and the relay 13 is turned on. Therefore, when the relay 7 does not turn off even after the lapse of a predetermined time, the second timer device 11
The port A becomes low and the transistor 12 is turned off to turn off the relay 13 so that the heater 2 cannot be energized. As described above, according to the present embodiment, even if the first timer device 5 fails for some reason, the heater 2 circuit can be surely cut off.

Next, a second embodiment of the present invention will be described with reference to FIG.
In this embodiment, the port A of the second timer device 11 becomes Low only when the relay 7 does not turn off even when a predetermined time has elapsed, and the load 15 is heated by turning on the triac 14 so that the load 15 is turned off. By mounting it near the thermal fuse 4, the thermal fuse 4 is melted and the power supply to the entire heater circuit is cut off.

According to the present embodiment, if the first timer device 5 fails for some reason, the power supply to the entire circuit can be cut off regardless of whether the temperature control device has failed.

Next, the embodiment shown in FIG. 3 will be described with reference to FIG. In this embodiment, the port A of the second timer device 11 becomes Low only when the relay 7 does not turn off even when the predetermined time has come, the LED 17 is turned on by turning on the transistor 15, and the alarm 18 is sounded and used. Notify others of abnormalities.

According to the present embodiment, if the first timer device 5 fails for some reason, the user can be visually and audibly notified of the abnormality.

Furthermore, by using the first and third embodiments together, it is possible to shut off the heater and notify the user of the abnormality.

The same effect can be obtained with the triac or the solid state relay in the present embodiment.

The same applies to the triac shown in FIG. 2 whether it is a relay, a thyristor, a solid state relay, or a power transistor.

EFFECTS OF THE INVENTION As described above, the present invention provides a pair of press plates for heating clothes or the like by providing a heater on at least one side, a temperature control means for controlling the temperature of the press plates, and a heater circuit to the heater circuit manually. The first timer device that starts the energization of the device and starts the time measurement, and shuts off the heater circuit after a predetermined time, and the power is supplied to the heater circuit to start the time measurement, and the heater circuit is shut off after the predetermined time. Since the second timer device is provided, even if the first timer device fails during use, the second timer device can reliably shut off the heater circuit after a predetermined time. In addition, the abnormality notification means
The failure of the timer device can be accurately known.
