Description

Steam electric iron

The present invention relates to a kind of steam electric iron, it comprises that there is shell and base plate that can be heated by resistive of a rear heel an its rear end, and this flatiron can be in two kinds of putting positions, promptly, the ironing position that keeps flat by soleplate or lean against rest position on the heel, a dividing plate is arranged on the base plate, this dividing plate constitutes a vaporization chamber that is supplied water by cistern with a closure flap again, this chamber is distributed the chamber with steam on the one hand and is connected, distribute the perforate that has some outwards to distribute steam on the chamber, and it there are a so-called scale removal hole of leading to the flatiron rear portion and this hole with detachable sealer sealing of installing on the other hand.

In the known apparatus of this class, sealer be by stopper constitute and the scale removal hole will be suitable for inserting an instrument in vaporization chamber.Like this, the people who uses flatiron just can, such as with a screwdriver, remove to scrape the inwall of vaporization chamber, purpose is to carry out mechanical scale removal.The weak point of these utensils just is: the user cannot see the calcareous deposit in the vaporization chamber, scrapes firmly at random, therefore can not all scrape the vaporization chamber all surfaces, particularly difficult previous section that scrapes in this vaporization chamber.Thereby the removal incrustation scale is incomplete.In addition, it has also scratched the inner surface of vaporization chamber, and this all is the inner surface that will handle with adhesive coating usually in order to improve evaporation, has therefore destroyed coating again.On the other hand, between each descale operation and different thermal cycle process, all there are some gravelstone grey matter sheets to come off and enter and distribute in the chamber, finally can stop up sending-out hole.

Purpose of the present invention overcomes above these weak points exactly, and particularly will prepare a kind of can also will reducing cost simultaneously than the flatiron that is easier to remove continuously incrustation scale.

According to the present invention, sealer comprises the container of a dismountable recovery deposit of lime thing, it communicates with vaporization chamber through the baffling passage, especially when flatiron is in its rest position, makes the deposit of lime thing that is present in the vaporization chamber be deposited in this returnable.

Like this, just can reach automatically and remove continuously the purpose of vaporization chamber incrustation scale by the calcium carbonate returnable.In fact, when leaving standstill on each user leans against flatiron its rear heel, the calcium carbonate fragment that forms in vaporization chamber has been deposited in the returnable, in this container the calcium carbonate fragment is accumulated, and waits until that always the user takes out turned letter to returnable.Thereby just avoided the calcium carbonate fragment to enter into distributing the chamber stopping up sending-out hole.In addition, the user just needn't re-use the instrument descale.So vaporization chamber can have the common turning that can use and baffle plate realizing the arbitrary shape of optimal evaporation, because necessaryly never again go to have scraped each corner of this vaporization chamber with instrument from the de-sludging hole.In addition, people can be contained in this utensil on the ready-made base plate, and this has just demonstrated the casting mold economy for the producer.

Characteristics more of the present invention and advantage also can be in addition emphasized out in from behind the explanation again, with the form of example and with reference to several accompanying drawings, wherein:

Fig. 1 is the partial cutaway schematic of flatiron of the present invention;

Fig. 2 is the partial schematic diagram on the Fig. 1 that draws by larger proportion, and what its was described is according to calcium carbonate returnable of the present invention;

Fig. 3 be describe another kind of embodiment of the present invention, with the similar schematic diagram of Fig. 2.

The steam electric iron of representing on Fig. 1 and 2 comprises that there is shell 1 and base plate 3 by resistance 4 heating of a rear heel 2 its rear end.Therefore this flatiron can utilize two positions, that is, flatiron lies in ironing position on the base plate 3 or flatiron by being placed on the rest position (not showing) on the rear heel 2.A dividing plate 5 is arranged on the base plate 3, it and closure flap 6 constitute a vaporization chamber 7, this vaporization chamber is supplied water by cistern 8, this vaporization chamber distributes chamber 9 with steam on the one hand and communicates, some outside steam sending-out holes 10 are arranged on the chamber, it also has a so-called scale removal hole 11 of leading to the flatiron rear portion on the other hand, the detachable sealer jam-pack of installing in this hole.

According to the present invention, sealer comprises a dismountable deposit of lime thing returnable 12, this container communicates with vaporization chamber 7 through baffling passage 13, and especially it is quiet when putting the position when flatiron is in, and makes the deposit of lime thing that is present in the vaporization chamber 7 fall in the container 12.

Like this, when each user leaned against end 2 placements thereafter to flatiron, the calcium carbonate fragment that is present in the vaporization chamber 7 all was deposited in the container 12, accumulates in the there.In addition, because the baffling passage, there are some calcium carbonate fragments also may enter 12 li in the container that is in the ironing position to reciprocating motion that flatiron applied by means of the user.In fact, this motion has caused that in vaporization chamber 7 some can overflow the fluctuation of baffling passage 13.

Container 12 makes such as available thermosetting plastics or thermoplastic.In fact, it should be able to bear the high water temperature from vaporization chamber 7.Plastics have certain transparency in another embodiment, as polyester.Therefore, it can allow the user check that the dress of container 12 deposits situation.

Closure flap 6 is led in scale removal perforate 11, the edge 11 of described perforate ' constituted above-mentioned baffling passage 13 with regard to the dividing plate 5 of some and vaporization chamber 7.Closure flap 6 is generally aluminium sheet, and the simple hole-punching method of descale perforate 11 usefulness is made.Thereby the producer need not to change existing base plate, so also just saved foundry processing.

The bottom 14 of container 12 will be installed in the following and sealer of the horizontal plane at scale removal perforate 11 places and comprise that one extends to the ramp 15 of container 12 bottoms 14 from above-mentioned perforate 11, makes it resist deposit of lime thing in the container 12 to the backflow of vaporization chamber 7 under the situation of ironing position.

Like this, ramp 15 just can increase the burden of calcium carbonate in container 12.In fact, when flatiron is in the situation of ironing position, during flatiron reciprocating motion unexpectedly, the calcium carbonate particle has just slowed down speed on slope 15, so and described those therefore can not cross the particle that passage 13 flows to vaporization chamber 7 and just stayed in the container 12.

According to a kind of more welcome embodiment, sealer also comprises a conduit 16 except container, and the sealing of one end is installed in the outlet of scale removal perforate 11, and its other end then is equipped with a seal nipple 17 that connects together with container 12.Sealing joint 17 is preferably done with silicone.Insulation board 18 that makes with heat resistant plastice of closure flap 6 usefulness separates with shell 1, and conduit 16 forms parts and has an angled section that constitutes slope 15 with described insulation board 18.Insulation board 18 the most handy plastics make, and conduit 16 can be with comparalive ease made of mould pressing method, need not to involve to add product.

Container 12 and shell 1 all have some devices of locking mutually (interlocking device).

The fixing device of these reciprocal interlockings comprises: firm limited block 22 that becomes one with shell 1 and the flexible limited block that constitutes by joint 17, in order that container 12 can be enclosed between shell 1 and the joint 17 with elastic type.In fact, interlocking is fixing should be able to be born the pressure that is produced and keep the sealing of container 12 so that avoid water and any leakage of steam in vaporization chamber 7, and this may scald the user.Utilized the elasticity of joint for this reason.

Another advantageous feature according to the present invention.See as on Fig. 2, knowing.Cistern 8 is dismountable and is contained in the groove seat 19 at shell 1 rear portion that container 12 has a bayonet lock 20 that protrudes in the perforate 21, and this perforate is opened in groove seat 19 and from described groove seat can touch bayonet lock, just can unclamp container 12 so that push described bayonet lock 20.

This shows,, allow the user take out cistern 8 and pushed this bayonet lock 20 just, so just can pull down container for the calcium carbonate in the container 12 is poured out.The safety in utilization of this embodiment is higher, because container can unexpectedly not unclamp, bayonet lock 20 can directly not contact from the flatiron outside yet.

According to another embodiment of the present invention, such as represented on the image pattern 3, container has a release pin 23 that is in its back, makes container 12 just can unclamp when pushing above-mentioned release pin.

Like this, in order to pour out the calcium carbonate in the container 12, allow the user push above-mentioned alignment pin 23 just, this is in order to pull down container 12.This embodiment easy especially and also it be particularly suitable for the situation that the flatiron rear portion can not be dismantled or be not contained in to cistern.
