Particularly, first filters grate 8 and second filters grate 9 and is parallel to the advantage that the orientation of the longitudinal direction of base plate 2 has and is: when flatiron is placed by its base 32, especially at the memory period of non-flatiron duration of work or flatiron, avoid remaining on these and filter grate 8, the incrustation scale particles agglomerate of 9 upstreams is filtered on the

grate

8,9 at these.

This feature allows to avoid filtering the fast blocking of

grate

8,9, and allows to increase the service life of flatiron.

Owing to filter grate 8, this layout of 9, when flatiron 1 is placed by its base 32, remaining on the first incrustation scale particulate that filters grate 8 upstreams falls among the rear portion 42A of evaporator main chamber 42, so that the rear portion 42A of vaporization chamber 42 is as the memory block, the incrustation scale particulate gathers gradually this memory block and does not disturb the work of flatiron.

When flatiron 1 is arranged on its base 32, remain on the 44B place, rear end that the second incrustation scale particulate that filters grate 9 upstreams is stored in wing passage 44, this allows to be avoided the fast blocking of the second filtration grate 9.

And, use two continuous filtration grates and use bore to be the opening of smaller szie at the second filtration grate that is passed by steam at the mobile route of steam, allow to avoid the second filtration grate very rapidly to be stopped up by large incrustation scale particulate.In fact, because this filter, to remain on evaporator main indoor so that maximum incrustation scale particulate filters grate by first, and so that only more the incrustation scale particulate of the smaller szie of smallest number can arrive second and filter grate.

At last, the anti stick coating of filtration grate allows to avoid incrustation scale to be attached on the filtration grate and stops up too soon the filtration grate.Be used for to filter advantage that the little flood rate of the material (for example glass fabric) of grate has and be a large amount of evaporations of avoiding the water droplet that can contact with overheated filtration grate, this allows to be limited in incrustation scale formation of filtering on the grate.

Therefore, this flatiron does not exist because the filtration grate is stopped up rapid out of use danger by incrustation scale, and can use for many years.

Therefore solved the problem that the incrustation scale particulate is discharged by this filter, the incrustation scale particulate of these discharges daily fabric of when flatiron, making dirty, and also the user is also very inconvenient perceives.Diameter full-size is that the incrustation scale particulate of 0.6mm is visible hardly by the base plate discharge, and the user is acceptable.

Certainly, the present invention is limited to absolutely not described above and only with the embodiment shown in the form of example.Therefore in the situation that does not break away from protection domain of the present invention, can change, particularly replace by the formation of various elements or by technology is of equal value.

Therefore, implement in the modified example at one shown in Figure 7, second filters grate 9 can be fixed on the closing plate 7 and be positioned in the top of wing passage 44 in steam distribution loop.The advantage that this enforcement modified example has is to be convenient to assembling heating main body, and first and

second filter grate

8,9 can be positioned on the closing plate 7 in the step before being assembled in closing plate on the foundry goods.

In another not shown enforcement modified example, first filters grate can be fixed on the closing plate each opening part at the side opening of distribution of steam passage, the advantage that this enforcement modified example has is to make the first filtration grate leave the evaporator main chamber, arrives the first probability that filters on the grate thereby reduced unevaporated little water droplet.

Implement in modified example at of the present invention another, flatiron of the present invention can only comprise a filtration grate that is arranged on the steam distribution loop, this opening size that filters grate at sidepiece between 0.2mm and 0.6mm.
