Description

[0002] Electric Steam Iron [0003]

The present invention relates to an electric steam iron having a tank module detachably mounted in the tank mounting groove of the housing in the longitudinal direction.

As a conventional electric steam iron, for example, disclosed in Korean Utility Model Publication No. 2000-5286, has been proposed.

1, a conventional electric steam iron is provided with a heater 13 to which a power cord is connected on a plated plate 12 provided below a body 11 having a large number of parts, A steam discharge tank 15 having a plurality of injection holes 16 formed on the lower side thereof is provided. A steam generating tank 17 is provided in the body 11 above the heater 13 and a water tub 19 is connected to the steam generating tank 17 by a connection hose 20.

The steam generating tank 17 and the heating tank 21 are connected to each other by the steam passage 22 and the heating tank 21 is connected to the heating tank 21. [ (21) and the steam discharge tank (15) are connected to each other by a supply pipe (18).

The conventional electric steam iron having such a configuration is heated by connecting the power cord 14 to the power source and operating the control knob (not shown) so that the heater 13 is heated to heat the smoothing plate 12, the steam generating tank 17, 21).

In this state, when water in the water tank 19 is supplied to the steam generating tank 17, steam is generated while being evaporated. The steam generated at this time is usually 110 ° C. The steam thus generated flows into the heating tank 21 through the steam passage 22 and is heated again by the heating tank 21 heated by the heater 13 to be secondarily heated to about 130 ° C. The heated steam flows into the steam discharge tank 15 through the supply pipe 18 and is ejected to the outside through the injection hole 16 as the valve not shown is depressed.

In the conventional electric steam iron, since the water supplied from the water tank 19 is firstly heated in the steam generating tank 17 and then heated again in the heating tank 21, high temperature steam not including liquid water is ejected .

However, since the primary heating and the secondary heating are performed in the same plane of the steam generating tank 17, a relatively wide area is required to obtain a predetermined evaporation rate, which does not contribute to the slip of the iron.

Since the water tank 19 is connected to the connecting hose 20 formed on the upper portion of the body 11, water flows smoothly into the steam generating tank 17 due to gravity. However, The overall height of the steam iron becomes high.

Further, since there is no pump, stable water can not be supplied to the steam generating tank 17, and unstable steam can be ejected.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an electric steam iron having a minimized total height while using a detachable tank module.

To achieve the above object, an electric steam iron according to claim 1 of the present invention comprises:

A tank module containing water; An instantaneous heating heater module for spraying water of the tank module with steam; The housing includes a tank mounting groove into which the tank module is detachably inserted back and forth.

The tank module 500 includes a tank member and a locking member for locking the tank member to the tank mounting groove 120, as shown in Figs.

The tank member includes a water tank 510, a tank body 520 in which the tank 510 is inserted, a tank cover 540 installed on the front surface 511 of the tank 510, a water inlet port 541, And a lid 550 for opening and closing the lid. Reference numeral 513 denotes an engagement flange which is engaged with the tank body 520.

The tank 510 has a wider surface and a streamlined shape.

The tank body 520 allows the tank 510 to be inserted and supported.

A water inlet 541 and a water outlet 543 are formed in the tank cover 540.

The water inlet 541 is opened / closed by a lid 550.

The lid 551 is connected to the lid 550 by a string 553 which is hooked to the water outlet 543. Therefore, since the lid 550 is hung on the water outlet 543, the lid 550 is prevented from being lost, and appearance cleanliness is neat.

The water outlet 543 is preferably provided with an on-off valve 580 which is opened or closed by the water inlet 710 of the electronic pump 700.

The opening / closing valve 580 includes a valve chamber 581 in which a water outlet 543 is formed, a cap 583 mounted in the valve chamber 581, and a return valve 583 interposed between the cap 583 and the valve chamber 581 And a spring 586.

As shown in Fig. 10, a valve seat 584 for opening and closing the valve chamber 581 is formed in the cap 583, and a protruded spacer 585 is formed on the entire surface.

The spacer 585 forms a gap between the cap 583 and the water inlet 710 so that the valve seat 584 is pushed back to smoothly flow into the water inlet 710 when the valve chamber 581 is opened.

It is preferable that an O-ring 587 is provided in the valve chamber 581 in front of the cap 583 in terms of leakage prevention.

The locking member includes a tank 510 and a locking hook 530 installed on the tank body 520 and locked to the housing 110.

The locking hook 530 is constituted by a hook 531, a pressing projection 533 and an elastic restoring piece 535 which are hooked on the locking jaw 127.

The resilient restoring piece 535 is disposed between the tank 510 and the tank body 520 in a U shape and the pushing protrusion 533 is pulled out through the withdrawing hole 521 of the tank body 520.

Therefore, when the pressing projection 533 is pressed, the locking hook 531 is released to the locking jaw 127 while the elastic restoring piece 535 is broken. The tank module 500 is pulled back and the tank module 500 is pulled back.

When the tank module 500 is pushed into the tank mounting groove 120 as it is, the retaining hook 531 is caught by the locking jaw 127 while the elastic restoring piece 535 is broken, 535 are unfolded and locked.

The tank module 500 slides forward and rearward and is arranged in front of and behind the water inlet port 710 and the water outlet port 543 of the electronic pump 700 so that the water flowing out from the bottom of the tank 510 flows well, (560) is connected to the water outlet (543) by the tube (570).

The water outflow weight 560 is formed of a weight with weight, and it is preferable that the water outflow pore 560 is formed with a water outflow hole.

Therefore, since the water outflow weight 560 touches the bottom of the tank 510, the water pump 560 functions like a submersible pump, so that even the bottom water can flow out.

The tank module 500 and the electromagnetic pump 700 are arranged side by side so as to reduce the height of the entire housing. In particular, the tank module 500 and the electromagnetic pump 700 can be slidably mounted on the front and back of the tank module 500, The overall surface area can be widened and the overall height can be reduced. Therefore, it can contribute significantly to the slimming of the electric steam iron (the shape in which the left and right widths are narrower than the front and rear lengths).

The electronic pump 700 includes a water inlet 710 and a water outlet 730 connected to the water inlet 551 and is controlled and controlled by the controller 700.

The electric pump 700 forcibly supplies the water in the tank 510 to the instantaneous heating heater module 300 according to the user's signal so that the steam can be stably sprayed from the steam jetting port 371. [

The control unit 900 includes a controller 910 having a switch 935 and a push button 930 for interrupting the switch 935. Restoration of the push button 930 is performed by a return spring 931. [ The controller 910 is mounted on the bracket 920 of the right housing 110b and when the push button 930 is pushed, the button LED 933 which emits light is electrically connected.

The controller 910 controls the electric heater 310, the temperature sensor 320, and the electric pump 700.
