Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an iron control device used in a general household.

2. Description of the Related Art Conventionally, in this type of iron, as shown in FIG. 5, a base 2 in which a heater 1 is embedded, a handle 3 provided above the base 2, and a power supply to the heater 1 are controlled, and Base 2
The temperature setting means 4 that can arbitrarily set the temperature and the power cord 5 that supplies electric power to the heater 1 are provided. The temperature setting means 4 is of a dial type, and when the dial is rotated to set the temperature of ironing, the heater 2 is energized, the base 1 is heated, and ironing can be performed.

Problems to be Solved by the Invention However, in the case of the temperature setting means 4 of the dial type, once the temperature is set by turning the dial, the dial is turned off again so that the heater 2 is de-energized. Power could not be stopped without turning to the position. Therefore, after the worker finishes ironing, forgetting to return the temperature setting of the temperature setting means 4 to "off", and the power cord 5
Unplug from the power supply, and after a while, reconnect the power cord 5
When the power is turned on, since the temperature setting before the power is turned on is kept as it is, the heater 1 is immediately energized and the base 2 is heated, and the operator mistakenly touches the base 2. There is a risk of burns due to burns and the risk of charring or burning of the textile by performing the above operation while the iron is placed on the textile with the base 1 facing down, causing a fire in the worst case. was there.

Therefore, the present invention solves such a conventional problem and further enhances the safety of the iron.

Means for Solving the Problems In order to solve the above problems, the present invention provides a base heated by a heater, and a temperature setting means for arbitrarily setting the temperature of the base and maintaining the set state. ,
A thermostat that controls energization to the heater so that the temperature of the base surface reaches a set temperature, a heater circuit switch circuit configured in series with this thermostat, a state detection unit that detects the posture state of the iron, A control circuit for controlling the heater circuit switch according to the output of the state detection means, wherein the heater circuit switch is held in an open state at the start of energization of the iron, and the posture of the iron is changed by the state detection means. It is designed to be closed after the detection of.

Action The action of this technical means is as follows. That is, even if the power cord is plugged into the outlet while the iron temperature is not set to "OFF", the heater circuit switch is in the open state and the heater is not energized. As a result, the user may get accidentally burned, or the iron may
There is no risk of burns or burns even if electricity is applied when the product falls on the floor, tatami, etc., and safety can be improved.

Example Hereinafter, one example of the present invention will be described with reference to the accompanying drawings. 1 to 4, 6 is a base in which the heater 7 is embedded, 8 is a handle provided above the base 6, and 9 is a temperature setting means capable of arbitrarily setting the temperature of the base 6. Reference numeral 10 is a heater control means constituted by a thermostat or the like for controlling energization of the heater 7 so that the base 6 reaches a set temperature. Reference numeral 11 is a heater circuit switch which is configured in series with the heater control means 10 and includes an electromagnetic relay and
A triac or the like may be used. Reference numeral 12 is a state detecting means for detecting the state of the iron, which is a reflection type photo sensor 13, a ball 14 as a reflecting object, and an inclined groove for guiding the ball 14.
It is composed of a case 16 having 15 and a lid 17. The operation of the state detecting means 12 will be described in detail. When the iron body is stationary in a horizontal state for ironing or a state close to the horizontal state, as shown in FIG. The phototransistor of the reflective photosensor 13 is in the ON state because it stands still at the bottom of the inclined groove 15, that is, at a position facing the reflective photosensor 13. Further, as shown in FIG. 3, when the iron body is placed in a self-supporting state or a state close to it, the sphere 14 will be a reflection type photo sensor.
The phototransistor of the reflection type photosensor 13 is turned off because it does not stand still at a position facing the position 13. As described above, the reflection type photo sensor is provided by the state detecting means 12 having the above-mentioned configuration
When the 13 phototransistor is OFF, the iron is in a self-supporting state, when it is ON, it is in a horizontal state, and when ON / OFF signals are repeatedly output, it can be detected that it is in use. Reference numeral 18 is a control circuit composed of a plurality of electronic components for controlling the heater circuit switch 11 in accordance with the output of the state detection means 12, and the heater circuit switch is first opened even when the iron is energized. The heater circuit switch is closed after it is held and it is judged by the state detection means 12 that the iron has been moved.

The operation in the above configuration will be described. Even if the user mistakenly sets the temperature setting means 9 to other than "off" such as "high" and energizes the iron, the heater circuit switch keeps the open state. Is not energized. Then, the user intentionally performs the iron from the horizontal state to the independent state, or from the independent state to the horizontal state, or performs the ironing operation in the horizontal state, that is, if the iron is moved,
This is detected by the state detection means 12 and the heater circuit switch
11 is closed, and the energization of the heater 7 is started. Thus, even if the power cord is inserted into the outlet, the heater 7 is not energized unless the iron is intentionally moved. Therefore, unlike the conventional method, the temperature of the base 6 rises while the user is not aware of it, and the base 6 is accidentally touched and burned, or the iron is energized on the clothes, the floor, the tatami etc. It does not burn out or, in the worst case, cause a fire. In addition, even if there is a power failure while using the iron, the power cord is left in the outlet as it is, and the power failure is restored again, the heater circuit switch 11 is in the open state and until the iron is moved again. Since the heater 7 is not energized, the safety can be improved.

In the above embodiment, the heater 7 is not energized until the iron is moved after energization even in the self-supporting state.
In the self-supporting state, the base 6 is in a relatively safe state without directly touching clothes or tampering. Considering usability, the heater circuit switch 11 should be opened simultaneously with the start of energizing the iron only in the self-supporting state. The heater 7 may be energized by closing it.

As described above, according to the present invention, the base heated by the heater, the temperature of the base is arbitrarily set, the temperature setting means for holding the set state, and the temperature of the base surface are set. A thermostat that controls the energization of the heater so as to reach the temperature, a heater circuit switch that is configured in series with the thermostat, a state detection unit that detects the posture state of the iron, and a heater circuit that is output by this state detection unit. A control circuit for controlling the switch is provided, and the heater circuit switch is held in an open state at the start of energization of the iron, and is closed after the state detecting means detects that the posture of the iron has changed. By
Even when the iron is connected to the power source, the iron is not inadvertently heated, and there is no risk of an operator accidentally touching the heated base and being burned, so that the iron can be used safely.
