[0019]

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

(Embodiment 1) As shown in FIGS. 1 and 2, an iron body 1 includes a base 3 having a vaporizing chamber 2 formed therein.
A tank 4 for supplying water to the vaporization chamber 2, a heater 5 for heating the base 3, temperature detecting means 6 such as a thermistor for detecting the temperature of the base 3, and temperature setting for arbitrarily setting the temperature of the base 3. Control means 9 including means 7 and attitude detecting means 8 for detecting whether the state of the iron body 1 is horizontal or independent.
Controls the power supply to the heater 4 by the output of the temperature detecting means 6 to control the temperature of the base 3 to the temperature set by the temperature setting means 7.

The temperature setting means 7 arbitrarily sets the temperature of the base 3 and can set the temperature in three stages. The set temperature is displayed on the display means 10. The display means 10 includes display units 10a, 10b, 10c, and 10d formed by light emitting diodes or the like.

As shown in FIG. 3, the posture detecting means 8 is disposed within the grip portion 11 of the iron main body 1 and mounted on a printed wiring board 12, a reflective photosensor 13 and a sphere 14 as a reflector. The inclined groove 1 for guiding the ball 14
5 and a lid 17.

When the inclination angle of the iron body 1 is equal to or less than a predetermined angle, as shown in FIG. 3B, the ball 14 is positioned at the lowermost part of the inclined groove 15 of the case, that is, at a position facing the reflection type photosensor 13. , The reflection type photosensor 13 is turned on, and this state is a horizontal state. When the angle of inclination of the iron body 1 is equal to or larger than a predetermined angle, FIG.
As shown in (a), the sphere 14 is located at a position not facing the reflection type photosensor 13, the reflection type photosensor 13 is turned off, and this state is a self-standing state.

As shown in FIG. 4, when the attitude detecting means 8 detects the self-sustained state, the control means 9 determines that the state is not in use and uses the temperature Ta set by the temperature setting means 7 as the base 3. When the horizontal state is detected, it is determined to be in use, and the temperature of the base 3 is controlled to a temperature higher by a predetermined amount T1 than the temperature Ta set by the temperature setting means 7.

Further, the control means 9 is configured to temporarily output a horizontal signal even if the signal of the reflection type photosensor 13 is turned on / off by the ball 14 of the posture detecting means 8 moving the iron body 1 back and forth during ironing. That is, when the reflection type photosensor 13 outputs an ON signal, the set temperature increased by the predetermined amount T1 is not changed immediately, but is maintained for a predetermined time. As a result, the set temperature higher by the predetermined amount T1 is maintained even in the back and forth movement of the iron during ironing.

The operation of the above configuration will be described.
When performing ironing, a power plug is inserted into an outlet and power is supplied to the entire iron body 1. In this state, the iron body 1 is in the "OFF" state, the control unit 9 does not energize the heater 5, and the display unit 10 turns on the display unit 10a representing this. The operator operates the temperature setting means 9 to set a desired temperature. The display means 10 lights the display units 10b to 10d according to the setting. The display means 10 is blinking until the temperature of the base is within the usable temperature range.

Here, when the temperature setting is set to the maximum temperature,
The display unit 10d starts blinking accordingly. Normally, the iron main body 1 is placed in a self-standing state, and the control unit 9 supplies power to the heater 5. Attitude control means 8
Since the sphere 14 becomes as shown in FIG. 3A and the reflection type photosensor 13 has no signal reflection, it judges that it is independent and outputs this to the control means 9.

The control means 9 inputs this, and energizes the heater 5 until the temperature reaches a temperature Ta set in advance by the temperature setting means 7, thereby heating the base 3. When the temperature reaches a preset temperature Ta, the power supply to the heater 5 is turned on / off to set the temperature Ta.
Control so that When the set temperature Ta is reached, the display means 10 turns on the display unit 10d from blinking.

When the display section 10d of the display means 10 is turned on, the worker starts ironing. First, the iron main body 1 is placed in a horizontal state and moved so that the wrinkles of the clothes are stretched. In this case, the posture detecting means 8 enters a state as shown in FIG. 3B, and the reflective photosensor 13 receives the reflection from the ball 14 and detects that it is horizontal. By detecting that it is horizontal, the control means 9 changes the set temperature from a preset temperature Ta to a temperature higher by a predetermined amount T1.

The control means 9 keeps the set temperature at a temperature T1 higher than Ta for a while even if the ball 14 moves back and forth due to the iron body 1 moving back and forth and the output of the reflection type photosensor 13 is turned on / off. . Therefore, even if water is sent from the tank 4 to the wet clothing or the vaporization chamber 2 to generate steam, the heat of the base 3 is deprived, and the set temperature is increased by the predetermined amount T1. Before the temperature decreases, the heater 5 is energized to supply heat to the base 3, thereby covering the temperature decrease of the base 3.

Subsequently, when the iron body 1 is made to be self-supporting by cloth cutting, the attitude control means 8 becomes as shown in FIG. 3A, and the reflection type photosensor 13 becomes self-supporting because there is no reflection signal from the ball 14. And immediately return the set temperature to the original temperature. Further, when the ironing is continued, the posture detecting means 8 detects the horizontal, and the temperature setting means 7 raises the set temperature again by a predetermined amount.

As described above, when the iron main body 1 is leveled by the posture detecting means 8 and the iron main body 1 is in the use state, the set temperature is increased by a predetermined amount, so that the clothes and the clothes in the case where the iron main body 1 is in the use state can be obtained. Due to steam generation,
A sharp drop in temperature can be prevented, and the effect of smoothing wrinkles can be maintained and improved. Further, from this state, the state changes to the non-use state, and if the posture detection means 8 detects independence and detects the non-use state, the control means 9 sets the preset temperature to the previously set temperature.
Unnecessary power consumption can be reduced while the set temperature is high.

When the iron body 1 is leveled, the predetermined amount T1 of the temperature to be raised is equal to the wrinkles of the clothes even if heat is taken to vaporize water in the vaporizing chamber 2 during the clothes or steam. It is desirable to set the temperature so as not to impair the stretching effect, for example, 10 to 30 ° C., preferably 1 to 30 ° C.
5 to 25 ° C.

When steam is generated at a low temperature setting (about 120 ° C.), unless the set temperature is increased by a predetermined amount T 1, the temperature of the base 3 drops to a temperature at which water cannot vaporize. That the base 3 can maintain the temperature at which water can be vaporized by increasing the
This is very effective when ironing clothing set at a low temperature using steam.

In the case where the temperature can be set in a plurality of stages, if only the low temperature setting is to allow the set temperature to be increased by a predetermined amount, the minimum temperature is set when the set temperature is two and the set temperature is three. In the above, at least the minimum temperature setting and the temperature setting in the low temperature range are set so that the set temperature can be increased by a predetermined amount.

The set temperature when the set temperature is raised by a predetermined amount must not exceed the set temperature immediately above it. That is, when the set temperature is 120 ° C. and the predetermined temperature is set to be higher by 20 ° C., the temperature set in the upper stage must be set to 141 ° C. or more.

In the case of such a structure, when the ironing is performed and the iron body 1 is moved forward and backward, the ball 14 moves back and forth on the groove and on the reflection type photosensor 13 so that the output is turned on. Although the output is turned off, it is also possible to determine that the output is in use in such a case and raise the set temperature.

(Embodiment 2) As shown in FIG.
Numeral 8 designates a posture detecting means 8 as a state detecting means for judging a use / non-use state of the iron, and performs cloth cutting or the like by an independent signal from the posture detecting means 8, that is, an OFF signal of the reflection type photo sensor 13. The non-use state is determined, and the use state is determined based on the horizontal signal, that is, the ON signal of the reflection type photosensor 13.

Further, the control means 18 includes the timer means 1
9, the continuation of the self-sustaining signal is counted. If the self-sustaining signal is continued for a predetermined time t1 or more, the set temperature is set lower by a predetermined amount T2 than the temperature set by the temperature setting means 9 as shown in FIG. The temperature is controlled.

After the temperature is lowered by T2, if the horizontal signal is input again after the start of use, the temperature is set to be once higher by a predetermined amount T3 than the preset temperature.
The count is reset when the signal is switched from independent to horizontal and from horizontal to independent. Other configurations are the same as those in the first embodiment.

The operation will be described with the above configuration. As in the first embodiment, first, when ironing is performed, a power plug is inserted into an outlet and power is supplied to the entire iron body 1. In this state, the iron body 1 is in the "OFF" state, and the control means 18 does not energize the heater 5,
The display means 10 illuminates a display unit representing the display.

The operator operates the temperature setting means 9 to set a desired temperature. The display means 10 turns on a display unit according to the setting. The display 10 blinks until the temperature of the base 3 reaches a usable temperature range.

Here, when the temperature setting is set to the maximum temperature Tb, the display section 10d of the display means 10 starts blinking according to the temperature setting. Normally, the iron body 1 is placed in a self-standing state, and the control unit 18 supplies power to the heater 5. The attitude detecting means 8 determines that the ball 14 is as shown in FIG. 3A and the reflective photosensor 13 is self-supporting because there is no signal reflection, and outputs this to the control means 18.

The control means 18 inputs this, and energizes the heater 5 to heat the base 3 until the temperature reaches the temperature Tb set by the temperature setting means 7. Further, the timer means 19 counts the self-sustaining state. When the temperature reaches the set temperature Tb, the power supply to the heater 5 is turned on / off to control the temperature to the set temperature Tb. When the temperature reaches the set temperature Tb, the display 10 turns on the display 10d of the display 10 from blinking.

When the display section 10d of the display means 10 is turned on, the worker starts ironing. First, the iron body 1 is placed in a horizontal state, and moved so that the wrinkles of the clothes are stretched. In this case, the attitude detecting means 8 is in a state as shown in FIG.
It detects that it is horizontal by receiving the reflection from.

Subsequently, when the iron body 1 is made to be in an independent state by cloth cutting, the posture detecting means 8 becomes as shown in FIG. 3A, and the reflection type photosensor 13 becomes independent because there is no reflection signal from the ball 14. Thus, the timer means 19 resets the count and starts counting in an independent state.

Further, when ironing is performed, a horizontal signal is input, and the self-standing timer count is stopped. Further, when the iron body 1 is made independent, the timer means 19 resets the count and then starts counting again in the independent state. If, for some reason, the iron body 1 is left for a while with the power on, the count advances, and when the count exceeds a predetermined time t1, the timer means 19 outputs it to the control means 18.

The control means 18 receives the input and inputs the set temperature T
b is lowered by a predetermined temperature T2, and power supply to the heater 5 is turned on / off to perform temperature control. Further, when the ironing is restarted, the control unit 18 once sets the temperature to a temperature higher than the preset temperature Tb by the predetermined temperature T3, and then returns to the preset temperature Tb.

As described above, the iron main body 1 becomes independent by the posture detecting means 8 and the iron main body 1 is put into the non-use state. After the predetermined time t1 has elapsed, the set temperature Tb is lowered by the predetermined amount T2, whereby the iron main body 1 is lowered. It is possible to reduce wasteful power consumption when 1 is left unused.

When the operating state is detected and the attitude detecting means 8 detects the horizontal state and detects the operating state, the control means 18 temporarily raises the set temperature Tb by T3 from a preset temperature and then sets the set temperature Tb to T3. Since the temperature is set to Tb, even if the set temperature is lowered by T2, the wrinkle-stretching effect does not decrease.

It is needless to say that the predetermined time t1 is set to a time sufficiently longer than the time for which the self-sustaining state is usually achieved by ironing.

Further, in the present invention, an embodiment using an iron with a power cord has been described. In a cordless iron, when the iron main body is placed on a mounting table, it is used when not in use, and when the iron body is away from the mounting table. The same effect can be obtained when used.
