Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ironing device used for press finishing of clothes and the like.

[0002]

2. Description of the Related Art In recent years, so-called cordless irons in which a power cord is not led out from an iron body have become widespread. This type of cordless iron is composed of an iron main body and a mounting table. When the iron main body is mounted on the mounting table, the heater incorporated in the base of the iron main body is energized to heat the base, and the base is predetermined. After the temperature rises to 1, the iron body is taken out of the mounting table, and the iron body can be handled individually to conveniently perform ironing work. Then, the iron body is placed on the placing table when the work is paused, and the base is reheated to proceed with the ironing work.

However, when the object to be ironed is a thick cloth having a large area, the amount of heat absorbed by the cloth from the base is large, so that the ironing work is interrupted during a pause. It is not enough to place the iron body on the placing table, and the iron body must be placed on the placing table frequently even when the work is not in operation, resulting in a reduction in work efficiency.

Therefore, a relay cord that is electrically connected to the power source is provided on the mounting table so that it can be pulled out. When ironing thick cloth having a large area, the relay cord is pulled out from the mounting table and the tip of the relay cord is removed. By connecting the power plug to the iron body and continuously energizing the heater, the temperature of the base can be kept almost constant, and thick cloth with a large area can be efficiently ironed without interruption. A dual-purpose ironing device with a cordless cord is provided.

A temperature adjusting mechanism for controlling the temperature of the base by controlling energization to the heater is provided in the iron body, and the user operates the temperature adjusting mechanism through the operating body to adjust the temperature of the base to the cloth. It is possible to set the proper temperature according to the type of material.

[0006]

In the past, however, regardless of whether the cordless cord is used or not, the temperature adjusting mechanism controls the energization of the heater under the same condition to control the temperature of the base to a predetermined value. It is configured to maintain the set temperature.

However, in the usage form with a cord,
Since the heater is continuously energized via the relay cord,
Even if the iron body is taken out of the mounting table, the base is kept at almost the set temperature regardless of that, whereas in the cordless usage mode, when the iron body is taken out of the mounting table, the heater is turned off accordingly. Immediately after taking out the base, the temperature of the base is lowered, the operating time at the set temperature is shortened, and the work efficiency is reduced.

The present invention has been made by paying attention to such a point, and an object thereof is to efficiently iron the base by keeping the base at a preset temperature for a relatively long time even in a cordless usage mode. It is to provide a dual-purpose ironing device with a cordless cord that can carry out the above work.

[0009]

In order to achieve such an object, the present invention provides an iron body having a power supply terminal that is electrically connected to a heater of a base, and the iron body can be placed on the iron body. Accordingly, a mounting table having a power supply terminal that contacts the power supply terminal, and a relay cord that is provided on the mounting table and that can be selectively connected to the iron body and that connects the heater to the power supply according to the connection, A detection mechanism that detects whether or not the relay cord is connected to the iron body, and when the detection mechanism detects that the relay cord is connected to the iron body, the base keeps the set temperature. The base is maintained at a temperature higher than the set temperature when the energization of the heater is controlled and it is detected that the relay cord is not connected to the iron body. Wherein is obtained so as to include a control means for controlling the energization of the heater so.

[0010]

When the object to be ironed is a thick cloth having a large area, the relay cord is connected to the iron body. Then, this connection is detected by the detection mechanism, and it is judged that it is a usage mode with a cord.

When the relay cord is connected to the iron body, the heater is energized through the relay cord to heat the base, but in this case, it is judged through the detection mechanism that the cord is used. Therefore, the energization of the heater is controlled by the control means so that the base maintains the preset temperature H selected in advance.

In such a state, the lower surface of the base is pressed against the cloth to proceed with the ironing work. At this time, since the heater is continuously energized via the relay cord, the temperature of the base is constantly maintained at the set temperature H, and therefore, the thick cloth having a large area is continuously heated without interruption. The cloth can be pressed efficiently.

On the other hand, when a thin cloth having a relatively small area is targeted, the relay cord is removed from the iron body, the iron body is placed on the placing table, and the power feeding terminal is brought into contact with the power source terminal. The removal of the relay cord is detected by the detection mechanism, and it is determined by this detection that the cordless usage mode is used.

The heater is energized by the contact between the power supply terminal and the power supply terminal to heat the base. In this case, it is determined through the detection mechanism that the cordless usage mode is used. The energization of the heater is controlled by the control means so as to maintain the temperature (H + α) higher than the selected set temperature H.

In such a state, the iron main body is taken out from the mounting table and ironed. At this time, since the relay cord is not connected to the iron main body, it is possible to handle the iron main body in a single state, so that the ironing work can be performed smoothly and efficiently.

When the iron main body is taken out from the mounting table, the heater is de-energized, so that the temperature of the base is gradually lowered after the taking-out, but when the iron main body is placed, the temperature of the base is lower than the set temperature H. It is controlled to maintain a slightly high temperature (H + α), so the time required for the base to drop to an unsuitable temperature for ironing is prolonged, and therefore the number of times the iron body needs to be placed on the placing table is reduced. It is possible to efficiently carry out the ironing work.

When the temperature rises to a preset temperature H selected in advance via the temperature setting button 51, for example, 190 ° C. (target fabric-linen), this is detected by the temperature sensor 40 and the signal is sent to the microcomputer 49. Information with a code is input to the microcomputer 49 by turning off the detection switch 42. Based on the input of this information and the information input by the temperature sensor 40, as shown in FIG. The energization of the heater 2 is controlled by the microcomputer 49 so as to maintain the set temperature H (190 ° C.).

In such a state, the iron body 1
Is taken out from the top of the mounting table 10 and the lower surface of the base 3 is pressed against the cloth to proceed with the ironing work. At this time, the heater 2 is continuously energized via the relay cord 26, so that the temperature of the base 3 is constantly maintained at the set temperature H, and thus the thick cloth having a large area is continuously heated without interruption. It is possible to press the fabric efficiently by adding.

On the other hand, in the case of a thin cloth having a relatively small area, the iron body 1 to the power supply plug 30 are used.
And the relay cord 26 is wound around the cord reel device 24. Then, in this state, as shown in FIG. 1, the iron body 1 is placed on the placing table 10, and the power supply terminal 8 is brought into contact with the power source terminal 15.

Is taken out from the table 10 and ironed. At this time, since the relay cord 26 is not connected to the iron main body 1, the iron main body 1 can be handled alone, and thus the ironing work can be performed smoothly and efficiently.

In the case of such a cordless usage mode, the iron main body 1 is placed on the placing table 10 during a temporary break between the ironing operations. Correspondingly, the base 3 is heated each time.

When the iron main body 1 is taken out from the mounting table 10, the heater 2 is de-energized, so that the temperature of the base 3 is gradually lowered after the taking-out.
However, when the iron body 1 is placed, the base 3 has the set temperature H.
The temperature is controlled to be maintained at a temperature (H + α) that is slightly higher than the above temperature, so that it takes a long time for the base 3 to fall to an unsuitable temperature for ironing, and thus, the mounting table 10 can be used.
The number of times the iron body 1 needs to be placed on the iron is reduced, and the ironing work can be performed more efficiently.

In the above embodiment, the first lever 43 that moves up and down and the second lever 44 that moves horizontally are used as a detection mechanism for detecting whether or not the relay cord 26 is connected to the iron body 1. Although the mechanical means used is described as an example, it is also possible to use an optical means or a magnetic means, and in the above embodiment, when the relay cord 26 is connected to the iron body 1, the detection switch 4 is used.
2 is turned off and turned on when not connected to determine the presence or absence of the connection, but the reverse configuration, that is, relay cord 2
When the 6 is connected to the iron body 1, the detection switch 42
May be turned on and turned off when not connected to determine the presence or absence of the connection.
