An electric iron 100 having a safety device according to the present invention includes a heat plate 110 which is closely contacted for ironing a fabric, an iron body 120 fixed on the heat plate and having a knob 121, And a heating unit installed in contact with the heating plate 110 inside the iron body and heating the heating plate to maintain the heating plate at a constant temperature when external power is supplied The electric iron as claimed in claim 1, further comprising: a knob clasp (124) provided at one side of the knob and pivotable about a pivot axis (122); and a hinge A lifting bar 132 which is in close contact with the hinge lever so as to transmit a turning force generated by the rotation of the hinge lever to the lifting bar 130 and a lifting bar having one end fixed to the lifting bar, A guiding part 140 having a lifting part 134 protruding on the axis of the steel bar so as to be brought into contact with the lifting part and to be lifted up and guided by a guide hole 142 formed in the guiding part, And a spacing member 114 which is fixed to the lower portion of the guide portion and flows into the spacing guide hole 112 formed in the hot plate so as to raise the iron body 120 along the rising of the guide portion .

Here, the heating plate 110 and the iron body 120 correspond to the bottom of the conventional electric iron and the iron housing case, respectively. The heating plate and the finishing case satisfy the condition of the bottom plate and the finishing case for ironing, And the heat is transferred to the heat plate through the heat generating means. The heat exchanger is suited to a conventional electric iron, so a detailed description thereof will be omitted.

The handle 121 is provided on the upper part of the iron body 120 so that the user can easily grasp the ironing hand. The handle 121 is not limited to a particular shape or shape, Handles can be used.

In the electric iron according to the present invention, the handle 129 is provided at one side of the handle 121. The handle 129 can be rotated along the turning shaft 122 provided on the body of the iron, The elastic restoring portion 126 may be provided as a spring means so as to maintain the state of being separated from the handle. In this case, the elastic restoring portion 126 may be retained in a spaced apart state. .

The hinge lever 125, which has entered the inside of the iron body, is extended at one end of the handle latch part 124 to push the lift-up piece 132, which will be described later, The part can be raised or lowered.

The hinge lever 125 is pushed by a lever guide (not shown) provided on the iron body, so that the hinge lever 125 maintains a state in which the hinge lever 125 is in contact with the lifting /

The lift section 132 which is in close contact with the hinge lever 125 and transfers the turning force of the hinge lever to the lift bar 130 rotates the lift bar by a predetermined angle to raise the guide section 140 The lifting bar having one end fixed to the lifting section may include a lifting section 134 protruded on the lifting bar shaft so that the guide section 140 can be pushed up or down by the rotating lifting section .

The lifting bar 130 has a lifting piece 132 fixed to one end of the lifting bar 130. The lifting bar 130 has an elevated portion 134 projecting axially along the center of rotation CR and a descending portion 135 located on the axis, The hinge lever 125 rotates along the hinge axis and the elevation piece portion abutting on the hinge lever 125 is pushed in the direction of the heat plate 110 so that the elevation portion 134 raises the guide portion 140.

When the lifting piece portion 132 is provided in a flat plate shape and is not used, that is, when it is not gripped, the hinge lever touches the bottom portion 1321 corresponding to the front end portion of the lifting piece portion, The elevation section of the elevation bar moves upward from the bottom of the elevation section to the elevation section 1322 corresponding to the rear end section.

In order to allow the user to grasp the grip portion of the handle and complete the grasping operation, the user may rotate the hinge lever in the abutting portion, i.e., the bottom portion 1321 to the high portion 1322, in consideration of the small turning angle of the hinge lever. The hinge lever can be moved in a state that the hinge lever has a larger tilt angle than the bottom portion so that the hinge lever can rotate even larger than the tilt angle of the hinge lever. In order to rotate the hinge lever, Or may be a curved elongated shape.

Further, in order to prevent the durability from being lowered due to the continuous friction between the hinge lever and the lifting and slitting parts abutting against the hinge lever, a rotating means 1251 such as a rotating roller or a rotating ball may be interposed between the hinge lever and the lifting / have.

Further, in order to solve the troubles of gripping when continuous ironing is performed, a hook 128 may be further provided to apply a holding force in a state where one end of the handle clasp is pressed.

The hook portion may have a plate shape with a structure that can be slid into the hook housing 129 provided in a shape of being housed in the iron body 120, and the hook housing 129 may have a shape in which the hook portion slides A conventional guide supporting structure may be adopted in which the lid for pressing the upper portion of the plate is fixed to the connecting portion of the body or the body and the handle portion so that the hook portion plate can be slid in the form of an opening portion.

The hook switching portion provided at the upper portion of the hook portion protrudes into the exposure hole of the hitch housing so that the hook switching portion can be fixed to the hook switching portion by sliding the upper end of the hook latch portion when the iron is used for a long time, The iron can be kept in a safe state by sliding.

In addition, the rotation supporting portions 136 and 136 ', in which the holes are formed, may be fixed to the heating plate or the iron body so that the lifting and lowering bar can rotate so as to impart a supporting force for raising and lowering the guide portion.

It is needless to say that the rotation support portions 136 and 136 'may be provided at the front end, the rear end, or the middle portion of the lifting bar in order to provide a supporting force and to assure durability.

In addition, the guide part 140 is provided with a guide hole 142 formed in the iron body so as to be reciprocated in a stable manner during the lifting and lowering of the guide part 140 by the lifting bar, Member 144 may be provided.

The guide shaft member 144 may be fixed at one end thereof to an upper portion of the heat plate 110 to guide the guide portion 140. In order to prevent the guide portion 140 from contacting the heat plate, (144 ') larger than the hole inner diameter of the guide hole (142).

A restoration support part 146 is provided on the upper part of the guide part 140 so as to be fixed to the iron body and a guide restoring part 148 is interposed between the guide part and an elastic force member such as a spring means, The restoring force can be given by the lever 134 when the lifting / lowering operation is performed.

A spacing member 114 is provided under the guide unit 140 to move up and down to a spacing guide hole 112 formed in the heat plate 110 so as to raise the iron body 120 along the guide portion The spacing member 114 may be provided in a bar shape that flows into the spacing guide hole and lifts the heating plate 110 by a safety distance D for preventing fire from the ironing floor.

Meanwhile, the electric iron according to the present invention includes an attitude control sensor S1 and an acceleration sensor S2 for preventing a fire that may occur when a user is left empty at the time of ironing, And a circuit for shutting down the power applied to the heat generating means when a signal which is not received or inverted by the attitude control sensor is received.
