Description

[Detailed Description of the Invention] This invention relates to a cordless ironing device in which the power cord is not led out from the iron body.

In a general electric iron, a power cord is led out from the main body, and power is supplied to the heating element through the power cord.

However, when the power cord is led out from the iron body in this way, the power cord becomes a hindrance during ironing, and the movement of the iron body is restricted by the length of the power cord.

Therefore, recently, we have constructed a mounting stand separate from the iron itself.
A power terminal is provided on this mounting stand, and a power supply terminal is also provided on the iron body, and by placing the iron body on the mounting stand, both terminals are connected and power is supplied to the heating element, which is used for actual ironing. An iron has been developed in which the main body of the iron can be taken out from the table and used.

In such an ironing device, if the power supply terminal and the power supply terminal are in contact with weak pressure, the two terminals may come close to each other little by little when vibrations are applied, etc., and an arc will occur between the contact parts, making it impossible to use the ironing device. Not only does it make people feel uneasy,
Both terminals wear out quickly, resulting in poor contact.

Conversely, if the power supply terminal is a pin and the power supply terminal is a cylindrical body, and the pin is press-fitted into the cylindrical body and the two ends are brought into contact with each other with strong pressure, there will be a large resistance when the iron body is taken out from the table. , which impedes workability.

This idea was developed with this in mind, and its purpose is to ensure that the power supply terminal and the power supply terminal are always in contact even when subjected to vibrations, etc., and that the iron itself can be removed from the mounting table. It is an object of the present invention to provide a cordless ironing device that can be easily and efficiently removed without encountering particularly large resistance.

An embodiment of this invention will be described below with reference to the drawings.

In the figure, 1 is an iron main body, and 2 is a mounting table.

The iron main body 1 is constructed by covering the upper surface of a base 4 into which a heating element 3 is cast with a cover 5, and attaching a synthetic resin grip 6 to the upper surface of the cover 5.

The grip body 6 integrally has a grip portion 7 at its upper end and a storage portion 8 at its lower back end, and a cutout portion 9 is formed in the upper surface of the grip portion 7.

A band-shaped actuating body 10 is provided in the notch 9,
This operating body 10 has one end connected to the handle body 6 via a pin 11.
It is rotatably mounted on the

A normally closed switch 12 is provided on the bottom inside the grip part 7,
The operation button 12a of this switch 12 is
The middle part of the inner surface is in elastic contact.

A pair of power supply terminals 13.13 and an electromagnet 1 located between the power supply terminals 13.13 are provided at the bottom of the storage portion 8.
4 are provided.

The power supply terminals 13 and 13 are pin-shaped, and one end of each of them projects vertically to the lower side of the storage section 8, and the attraction section 15 of the electromagnet 14 is exposed on the lower surface of the storage section 8.

On the other hand, the mounting table 2 has a recess 16 on the upper surface, and this recess 16
is formed into a boat shape corresponding to the external shape of the base 4.

The upper surface of the rear end of the mounting table 2 serves as a power feeding section 17, and a pair of through holes 18.degree.

A support plate 19 is provided inside and below the power supply section 17, and a pair of power supply terminals 20, 20 are fitted into the support plate 19 so as to be vertically movable.

Springs 21.21 are attached to these power terminals 20.20, and each power terminal 20.20 is elastically biased upward by these springs 21.21, and the biasing force causes each power terminal 20, 20 to The upper end surface is the above-mentioned through hole 1B, 1B
It abuts against the periphery of the lower end of the opening so as to close it.

A power cord 22 is introduced from the rear end surface of the mounting table 2, and each lead wire 23.23 of this power cord 22 is connected to the power terminal 20.20.

Further, on the upper surface of the power supply section 17, the attraction section 1 of the electromagnet 14 is provided.
A magnetic body 24 such as an iron plate is attached in correspondence with 5.

FIG. 3 is an electrical circuit diagram, and as shown in this figure, the power supply terminals 20.20 are electrically connected to the power supply 25, and the power supply terminals 13.1
3, a series circuit of the heating element 3 and the thermostat 26, and a series circuit of the switch 12 and the electromagnet 14 are connected in parallel.

Note that 27 shown in FIG. 1 is a temperature adjustment dial for controlling the thermostat 26 and setting the temperature of the base 4.

Next, the effect will be explained.

When using this device, first the iron main body 1 is placed on the mounting table 2 so that its base 4 fits within the recess 16.

Due to this placement, the attraction part 15 of the electromagnet 14 comes into contact with the magnetic body 24, and the power supply terminals 13, 13 enter the through holes 18, 1B of the power supply part 17, and the power supply terminal 20.20 is pushed against the spring 21.21. and press the power supply terminal 1.
3.13 contacts the power terminal 20.20.

This contact energizes the heating element 3 via the thermostat and the electromagnet 14 via the normally closed switch 12, so that the base 4 is gradually heated by the heating element 3.

By energizing the electromagnet 14, a magnetic attraction force is generated in the attraction part 15, and the attraction part 15 is firmly joined to the magnetic body 24 by this attraction force.

In other words, the iron main body 1 is securely fixed to the mounting table 2.

Therefore, even if vibration or the like is applied to the mounting table 2 or the iron body 1, the power supply terminal 13.13 and the power supply terminal 20.20 will not come into contact with or separate from each other, and the contact state will always be maintained reliably, thus preventing arcing. This never occurs.

After the base 4 reaches a predetermined temperature, the user grasps the grip 7 with his or her hand, takes out the iron body 1 from the table 2, and performs ironing work. At this time, the operating body 10 rotates slightly downward about the pin 11 due to the grip pressure, and this rotation causes the operation button 1 to
2a is pressed, and the contacts of the switch 12 are opened.

By this opening, the power supply to the electromagnet 14 is cut off, and the magnetic attraction force of the attraction part 15 disappears.

Therefore, the iron main body 1 can be easily and efficiently taken out using only the force that resists the weight of the iron main body 1, without being subjected to any other resistance force.

In the above embodiments, the actuating body is shaped like a strip and one end of the belt is rotatably supported, but the present invention is not limited to such a configuration. It may be configured such that it is pressed by gripping the grip.

As explained above, this invention consists of an iron main body, which has a handle body having a grip part attached to a base equipped with a heating element;
An operating body provided on the grip portion of the handle body, a normally closed switch operated in conjunction with the operation of the operating body, a power supply terminal provided on the iron body and electrically connected to the heating element, and this power supply terminal. an electromagnet that is electrically connected through the switch, a mounting table on which the iron body can be placed freely, a power supply terminal provided on the mounting table that contacts the power supply terminal when the iron body is placed, and a power terminal that contacts the electromagnet. It is characterized by being equipped with a magnetic material, so even if vibrations are applied to the device while the iron body is placed on the mounting table, the contact state between the power supply terminal and the power supply terminal is always maintained. The iron body can be held securely to prevent arcing, and when the iron body is taken out from the mounting table, the iron body can be easily and efficiently worked without encountering any great resistance.
