Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an iron for general household use.

BACKGROUND OF THE INVENTION Conventionally, as shown in FIGS. 6 to 9, this type of iron has a base 2 having a heater 1, and a mercury iron that outputs ON and OFF signals depending on the horizontal and vertical positions of the iron. A horizontal/vertical detecting means 3 such as a switch, a movement detecting means 4 for detecting the reciprocating movement of the iron when the iron is in a horizontal state for ironing, and interlocking with the horizontal/vertical detecting means 3 and the movement detecting means 4. horizontal state,
The configuration includes a heater control means 6 that cuts off the power supply to the circuit of the heater 1 after a certain period of time has elapsed in the vertical standstill state. The motion detection means 4 includes a case 7 having a groove 6 of a constant width, a ball 8 movably placed on the groove,
It consisted of a reflective photosensor 9 for detecting this sphere 8.

Problems that the invention attempts to address However, with such a structure, there is no detection means for detecting whether the iron body is in a horizontal position for ironing operations or in a vertical position for leaving the iron upright. Apart from this, additional detection means are required to detect the reciprocating motion when the iron is in a horizontal state during the ironing operation, and it is difficult to install multiple detection means in the limited space inside the iron. Moreover, there is a problem in that it cannot be constructed at a low cost because of the large number of parts.

Therefore, the present invention makes it possible to detect the horizontal state, vertical state, and reciprocating state of the iron main body in the horizontal state with a single state detection means, which can be easily installed in the space inside the iron, and reduces costs. This product provides an iron that is cheaper and safer than other irons.

Means for solving the problems and the technical means of the present invention for solving the above-mentioned problems are: a case having a groove with an uneven width; a spherical movable body movably placed on the groove; The iron is composed of a photosensor that detects the body and activates a heater control means that cuts off electricity to the heater circuit, and the groove is equipped with a state detection means whose width is varied.

For production The effect of this technical means is as follows.

That is, detection of the reciprocating motion of the iron main body in the horizontal state, vertical state, and horizontal state can be determined by the change in the output of the reflective photosensor as the position of the movable body placed on one side on the groove of the case changes. In other words, when the iron is left in a horizontal position, the output of the photosensor is at a maximum at the position where the movable object is facing [n], and when the iron is placed in a vertical position, the output of the photosensor is at a maximum where the movable object cannot be detected. During the ironing operation, the movable object placed on the groove moves with the ironing operation, so the output of the reflective photosensor changes from maximum → minimum → maximum →... Detection becomes possible. In addition, the same detection is possible even if the output of the photosensor is configured to be minimum in the horizontal state and maximum in the vertical state, contrary to the above.

As a result, it becomes possible to detect the reciprocating motion of the iron body in the horizontal state, vertical state, and horizontal state with one state detection means, and it becomes possible to easily mount the state detection means in the space inside the iron.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In FIGS. 1 to 6, 1o indicates a pace having a heater 11, and 12 indicates a horizontal state of the iron body.

A state detection means 13 detects the reciprocating motion in the vertical state and in the horizontal state, and when the iron body is left in the horizontal state in response to the output signal from the state detection stage 12, the iron body is operated for a short time (T1). If the main body is left in a vertical position, the heater control means shuts off the power to the heater 11 circuit after a long period of time (T2). Here, the state detection means 12 includes a case 15 having a groove 14, a spherical movable body 16, and a movable body 16 that is most likely to be stable when the iron main body is in a horizontal state. It consists of a reflective photosensor 19 consisting of a phototransistor 17 and a light emitting diode 18 arranged with a gap directly below the wide position, and a lid 2° for preventing disturbance light from entering the reflective photosensor 19. There is.

To explain the operation in the above configuration, when the iron main body is left in a horizontal state, the movable body 16 moves to the widest position of the groove 14 of the case 15, that is, directly above the reflective photosensor 19, as shown in FIG. Is it a reflective photosen to stand still with a gap between the two? 19 light emitting diodes 1
The light output from the movable body 16 is reflected by the surface of the movable body 16 and does not enter the phototransistor 17, so that the output of the phototransistor 17 becomes maximum. When the iron body is in a vertical position, the movable body 16 is stationary at the end of the groove 14 of the case 15 as shown in FIG. 4, so the light output from the light emitting diode 18 of the reflective photosensor 19 is reflected. Since the object is not directly above the object, the reflected light does not return to the phototransistor 17, and the output of the phototransistor 17 becomes minimum. Further, when the iron main body is reciprocating during ironing operation, the movable body 16 moves on the groove 14 of the case 16, so the light output from the light emitting diode 18 is reflected by the phototransistor 17. The output of the phototransistor 17 repeatedly changes from maximum to minimum and from minimum to maximum over time. Here, if the output of the phototransistor 17 is electrically processed so that it is turned on at the maximum output side and turned off at the minimum output side, it will be turned on when left in the horizontal position, turned off in the vertical position, and turned off when ironing. During operation, an output signal that repeats ON and OFF is obtained from the reflective photosensor 19. Next, receiving this output signal,
If the output signal remains ON for a short fixed period of time (T), the heater control means 13 operates to cut off the power supply to the heater 11 circuit. In addition, the output signal of the reflective photosensor 19 is turned off before the ON state elapses for a short fixed period of time (T1).
If the output signal changes to ON, the time from the point of inversion is counted, and if the output signal turns ON again before this OFF state has elapsed for a long certain period of time (T2), a short certain period of time (T1) has elapsed from that point. Otherwise, the heater 11 circuit will not be cut off.

Therefore, if the iron is left standing upright, the power to the heater 11 will be cut off after a long certain period of time (T2), which will prevent unnecessary power consumption and the occurrence of a fire. This can be prevented, and if the iron body is installed in a horizontal state, the power to the heater 11 will be automatically cut off after a short fixed period of time (T1) has elapsed.
It is possible to prevent clothes from being scorched or a fire to occur due to an accident of improper use, and a safety mechanism such as not cutting off electricity to the heater 11 during ironing operation can be realized by using one condition detection means 12. Therefore, the iron can be easily installed in the limited space inside the iron, and the number of parts can be reduced to provide a cheaper iron.

In addition, in the above embodiment, an example was shown in which a reflection type photo sensor was used as a detector, but a facing type photo sensor may also be used.The point is that a movable object can be detected using optical means. Good to have.

Furthermore, in the above embodiment, an example was shown in which the output of the photo sensor is turned ON when the iron body is in a horizontal position, but conversely, when the iron body is in a horizontal position, the output of the photo sensor is turned ON.
It may be configured to be FF.

Effects of the Invention The present invention provides a case having a groove of varying width, a spherical movable body placed on the groove of this case, and a state detection means composed of a photo sensor. The horizontal state, vertical state, and reciprocating motion in the horizontal state are detected, and if left in the horizontal state described above, the
T1), the heater circuit is automatically cut off in the vertical position for a long time (T2), making it safe to iron.
The condition detection means can be easily installed in the space inside the iron, and since there are fewer parts, the price of the iron can be reduced, making it possible to provide a cheaper and safer iron.
