DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an iron for wrinkling clothes and the like.

[0002]

2. Description of the Related Art Conventionally, this type of iron has generally been configured as shown in FIGS. Hereinafter, the configuration will be described.

As shown in the figure, a heater 1 heats a base 2. Then, the temperature of the base unit 2 is detected by the temperature detection unit 3, and the detected temperature signal is output to the control unit 4. The control unit 4 sends the temperature signal to the temperature setting unit 5.
It is determined whether the temperature is higher or lower than the set temperature, and the result is output to the heater control unit 6. The heater control unit 6 controls the power supply to the heater unit 1 to reduce the temperature of the base unit 2. It is configured to control to be constant. The display unit 7 displays a set temperature by operating the temperature setting unit 5, and is controlled by the control unit 4.

The state detecting section 8 detects the state of the ironing section 9, and if the heated ironing section 9 is left in a horizontal state, the cloth may be damaged. If the power supply to the heater unit 1 is cut off after the lapse of time and the self-standing state in which the tip of the base unit 2 is directed upward is continued, it is considered that the power has been forgotten to be turned off after the ironing operation is completed. Therefore, the power supply to the heater unit 1 is cut off after a relatively long time of about 10 minutes so as not to be cut off during a short pause during operation.

When the iron unit 9 is left in a horizontal state, the power supply to the heater unit 1 is not immediately interrupted because the iron unit 9 is used in a state where the iron unit 9 is kept stationary in a horizontal state due to stubborn wrinkles or iron print. This is because there are times.

[0006] Further, if the time until the power supply to the heater unit 1 is cut off is shortened when the heater unit 1 is left standing, the heater unit may be inadvertently operated during the operation of removing clothes during ironing. This is because a situation occurs in which the energization to 1 is interrupted.

The structure and operation of the state detecting section 8 will be described with reference to FIGS. 9 and 10. As shown in FIG. 9A, the state detecting section 8 includes a cover 10 made of resin,

[0008] A photo sensor 13 is mounted directly below the hole 12. As shown in FIG. 10, the photosensor 13 has a configuration in which a light emitting element 14 and a light receiving element 15 are juxtaposed in the same direction, and detects reflected light from the sphere 11.

As shown in FIG. 9 (a), when the ball 11 is below the slope provided on the cover 10, that is, when the iron 9 is in a horizontal state, when the light emitting element 14 emits infrared rays, Is reflected by the sphere 11 after passing through the hole 12, and the reflected light is received by the light receiving element 15.

Further, as shown in FIG. 9B, when the ball 11 is on the upper part of the slope, that is, when the iron 9 is in a self-supporting state, even if the light emitting element 14 emits infrared rays, The light is merely reflected irregularly on the inside, and is hardly received by the light receiving element 15.

When the user is ironing, the ironing section 9 is moved back and forth.
Since the state of (b) occurs repeatedly, it is possible to detect the state of the ironing unit 9 based on this state.

[0012]

In such a conventional structure, when the ironing section 9 is left in a horizontal state, the heater section 1 is kept energized for about one minute, so Had the problem of hurting.

As means for solving the above problems,
It is conceivable to determine whether the iron is in use or not based on whether the handshake set in the handle of the iron is grasped.However, in such a configuration, the handshake is difficult or difficult to grasp. There is a problem that the usability is poor, such as the need for power.

The present invention solves the above-mentioned problems, and detects whether or not the iron is in use without impairing the usability of the iron, and in the case of not using the iron, shuts off the power supply to the heater section. It is intended to provide.

[0015]

According to the present invention, in order to achieve the above object, the temperature of a base section is detected by a temperature detecting section, and a heater control section controls the supply of electricity to a heater section for heating the base section. The output of the light detection unit that detects external light and the output of the state detection unit that detects the state of ironing are input to the control unit to control the heater control unit. When the horizontal state is detected, and when the light detection unit detects external light, the heater control unit is controlled to cut off the power supply to the heater unit.

Thus, it is possible to detect whether or not the iron is in use by the output of the state detection unit and the output of the light detection unit. If the iron is not in use, the power to the heater unit can be cut off.
Safety can be improved.
