The utility model proposes a kind of ironing apparatus.

In the utility model embodiment, as shown in Figure 1 to Figure 3, which has ironing face 10, the ironing face 10 offer spray orifice (11a, 11b, 11c), and the boundary of the spray orifice (11a, 11b, 11c) is enclosed the enclosed area of strip Domain, the boundary of the spray orifice (11a, 11b, 11c) include positioned at the closed area long axis two sides and recess it is opposite first Segmental arc and the second segmental arc.

In the present embodiment, boundary shape, that is, spray orifice (11a, 11b, 11c) of spray orifice (11a, 11b, 11c) is in ironing face 10 On cross sectional shape, the boundary shape of spray orifice can be for oval (such as spray orifice 11a), water-drop-shaped (such as spray orifice 11b) or track type (such as Spray orifice 11c) etc., need to only meet spray orifice (11a, 11b, 11c) includes that recess is opposite and be located at the long axis two sides of closed area The first segmental arc and the second segmental arc.The long axis of closed area i.e. its longest dimension, and preferably the first segmental arc and second Segmental arc is in round and smooth arc line shaped.

The present embodiment is made by carrying out simulation ironing experiment to spray orifice of different shapes using the effective ironing area of single hole For one of the evaluation index of ironing effect.The effective ironing area of single hole refers to that after the effective ironing temperature value of determination, determination has The range of ironing temperature is imitated, and effective ironing area is calculated with this.Effective ironing area can intuitively reflect vapor action in Profiling temperatures when fabric surface.In simulated experiment, the effective ironing area of single hole can be by the image of thermal imaging at Reason software is calculated.In order to verify the present embodiment beneficial effect simulated experiment in effective ironing temperature be set as 50 DEG C, i.e., the gross area in region of the Temperature Distribution greater than 50 DEG C is effective ironing area in simulated experiment.In the simulated experiment Record comparison, effective bigger total ironing of explanation of ironing area are carried out to effective ironing area of the spray orifice of different cross section shape in journey Time is shorter, so that the whole ironing effect reflected is also more preferable.

As shown in table 1, this implementation is respectively adopted under the premise of other conditions are identical in the simulation ironing experiment of the present embodiment The spray orifice (11a, 11b, 11c) and rectangle spray orifice of example are tested and compare the effective ironing area data being collected into.Wherein, originally The homalographic diameter of a circle of the spray orifice (11a, 11b, 11c) of embodiment is 6mm.Ironing experiment simulation ironing apparatus is simulated in fabric On iron process, in the image processing software of thermal imaging interception simulation iron process when 1s, 5s, 10s, 15s and 30s Temperature distribution image, to obtain more stable temperature distribution image, the region by temperature greater than 50 DEG C is set as effective ironing area Domain, then by image conversion processing software, if ImageJ software calculates the digital value in effective ironing region, by the digital value Reference data as effective ironing area.

The simulation ironing experiment of the present embodiment also has collected the maximum temperature of ironing object center point in simulation iron process Tmax, and it is converted into temperature of zero dimension Tn, conversion formula are as follows:

Tn=(Ti-Tmax)/Ti, wherein Ti is the saturation temperature (100 DEG C) under steam normal temperature and pressure.Pass through reasoning and calculation It is found that temperature of zero dimension is positively correlated with effective ironing area, i.e., temperature of zero dimension is bigger, and effective ironing area is smaller, so Temperature of zero dimension can also be used for the experiment effect of Simulation ironing experimentation.

The comparison of the effective ironing area and temperature of zero dimension of 1 the present embodiment spray orifice (11a, 11b, 11c) of table and rectangle spray orifice

As shown in table 2, to further illustrate that the shape of the spray orifice (11a, 11b, 11c) of the present embodiment is Optimum cross section shape Shape, the present embodiment also use triangle, star and cross spray orifice to carry out simulation ironing experiment as the representative of other shapes, Effective ironing of the simulation ironing of this three and the present embodiment spray orifice (11a, 11b, 11c) is compared under the premise of other conditions are identical Area, with above-mentioned experiment the difference is that the homalographic diameter of a circle for the spray orifice that this simulation ironing experiment uses is 4mm.

2. triangle of table, star, effective ironing area of cross and the present embodiment spray orifice (11a, 11b, 11c) and immeasurable Guiding principle temperature comparisons

By in table 1 and table 2 it is found that under equal conditions, the effective ironing of stabilization of the present embodiment spray orifice (11a, 11b, 11c) Area is far longer than the other shapes of spray orifice such as rectangle spray orifice and triangle, star, cross, therefore ironing effect is also corresponding More preferably.In the course of work of ironing apparatus, steam is generated by the steam generator in ironing apparatus, then is projected from spray orifice, During steam jet, the interior temperature that can be mainly reflected as steam of steam, i.e. internal steam work is bigger, and temperature is higher, thus Effective ironing area is bigger and temperature of zero dimension is smaller.Influence internal steam work principal element have barometric gradient inside and outside spray orifice and The flow rate of fluid, wherein barometric gradient and interior energy are negatively correlated, and flow rate can be positively correlated with interior.

The corner angle of triangle, star and cross spray orifice are more, will cause when steam sprays interior during steam flowing The increase of external pressure force gradient, while also causing the dissipation of vapor stream speed so that internal steam work and kinetic energy are reduced, cause from The vapor (steam) temperature that spray orifice sprays reduces, and also relative reduction, ironing-time increase effective ironing area of steam, whole ironing effect Weaken.

The utility model ironing apparatus sets the boundary of spray orifice (11a, 11b, 11c) to include the first opposite arc of recess Section and the second segmental arc, on the short-axis direction vertical with the long axis on the boundary spray orifice (11a, 11b, 11c), due to the first segmental arc and the Two segmental arcs itself do not include corner angle, and therefore, the first segmental arc or the second segmental arc external and internal pressure change of gradient are more uniform, steam it is interior Energy loss is small, and then is conducive to form the bigger effective ironing area of area in section at the same time.Further, since the first arc The recess of section and the second segmental arc is oppositely arranged, and when the steam of ironing apparatus is sprayed from spray orifice (11a, 11b, 11c), steam is along spray Hole (11a, 11b, 11c) short-axis direction flowing velocity faster, and is in variation shape along the first segmental arc and the second segmental arc, fast speed Steam stream drives the slower steam stream of peripheral speed, is overlapped mutually again after the two diffusion, the effective ironing face shape eventually formed is more To be intended to circle, so that Temperature Distribution is more evenly, and then the ironing effect of ironing apparatus is improved.

Further, first segmental arc forms the closed area with the second segmental arc round and smooth connect.In the present embodiment In, it should be noted that the starting point and terminal for setting the first segmental arc are respectively S1, E1, if the starting point of the second segmental arc and terminal difference For S2, E2, S1 connects with S2, and E1 connects with E2, then tangent line and second segmental arc tangent line S2 at of first segmental arc at S1 is flat Row, then tangent line of first segmental arc at E1 is parallel with tangent line of second segmental arc at E2；That is the first segmental arc is with the second segmental arc in phase Connect place's rounding off.Closed area is further also shaped to ellipse in practical applications, so that spray orifice (11a, 11b, 11c) corner angle it is less, so that the external and internal pressure change of gradient on the boundary spray orifice (11a, 11b, 11c) is more uniform, steam Interior energy loss is smaller, and the effective ironing area formed in same time period is bigger, and ellipse is standard geometrical shapes, more It is easy to the concentrated processing of spray orifice (11a, 11b, 11c).

Further, the longest dimension of the closed area is a, shortest dimension b, and a/b≤3.In the present embodiment, As shown in table 3, the oval orifice 11a that simulated experiment uses area equation and a/b to be 3 for 1/1 and a/b carries out simulation ironing, And compare effective ironing area.It is understood that the longest dimension of ellipse is major axis dimension, shortest dimension is short axle Size.In this experiment, the homalographic diameter of a circle of two kinds of spray orifices is 6mm.

The effective ironing area and temperature of zero dimension of table 3.a/b=1 and a/b=3 compare

As shown in Table 3, the ratio of semi-minor axis length in the section oval orifice 11a is bigger, then effective ironing area is smaller, total ironing Time is longer, and whole ironing effect is worse, should be by the section spray orifice 11a most to make ironing apparatus keep enough ironing areas The ratio between long size and shortest dimension are set as a/b≤3.

Further, the ironing apparatus is hand-held Garment Steamer Machine, and the ironing face is axisymmetric shape, the closed area Long axis it is parallel with the symmetry axis in the ironing face.In the present embodiment, simulation ironing experiment is also using temperature distribution image Transverse and longitudinal is than one of the evaluation index as ironing effect.Transverse and longitudinal ratio is the transverse direction for simulating the temperature distribution image that ironing experiment generates The ratio between size and longitudinal size, i.e., the ratio between the lateral dimension and longitudinal size in effective ironing region.The transverse and longitudinal in effective ironing region Than illustrating that the distribution situation of ironing subject surface temperature is more intended to circle closer to 1, so that bulk temperature distribution is more Uniformly, make the ironing efficiency of ironing apparatus higher.

It should be noted that the symmetry axis in hand-held Garment Steamer Machine ironing face 10 in iron process usually with ironing object Longest dimension direction is parallel, therefore the longest line in the section spray orifice (11a, 11b, 11c) is flat with the longest dimension direction of fabric Row.As shown in table 4, in the identical situation of other conditions, boundary longest line and ironing face is respectively adopted in simulation ironing experiment The parallel spray orifice of 10 symmetry axis (11a, 11b, 11c) and the boundary the shortest route spray orifice parallel with the symmetry axis in ironing face 10, And simulated experiment is carried out on the ironing object of two kinds of unlike materials of cotton fabric and non-woven fabrics to exclude the material pair of ironing object It is influenced caused by experimental result.Wherein, the ratio of semi-minor axis length for the oval orifice 11a that simulation ironing experiment uses is respectively a/b =2 and a/b=3.

4. oval orifice 11a major cross-sectional axis of table is parallel with the symmetry axis in ironing face 10 and the section oval orifice 11a is short The axis effective ironing region transverse and longitudinal ratio parallel with the symmetry axis in ironing face 10

As shown in Table 4, on same ironing object and on the oval orifice 11a of same ratio of semi-minor axis length, long axis with press Effective ironing region of the parallel spray orifice of the symmetry axis of dough made with boiling water 10 spray orifice parallel with the symmetry axis in ironing face 10 compared with short axle Transverse and longitudinal ratio is closer to 1, i.e. the Temperature Distribution of ironing subject surface more levels off to circle, so that bulk temperature distribution is more equal It is even, keep the ironing efficiency of ironing apparatus higher, the longest line of closed area is preferably arranged to pair with ironing face 10 as a result, Claim axis parallel.

Further, as shown in table 5, simulation ironing experiment also show that the ratio of semi-minor axis length in the section oval orifice 11a is Effective ironing region transverse and longitudinal ratio when a/b=1, as shown in Table 5, a/b=2 and ellipse parallel with the symmetry axis in ironing face 10 of long axis The transverse and longitudinal in effective ironing region of round spray orifice 11a than the spray orifice compared with a/b=1 and a/b=3 closer to 1, therefore a/b =2 and the temperature of the ironing subject surface of spray orifice that extends along the direction of motion of long axis tend to circle, thus whole temperature It is distributed more uniform, ironing efficiency is higher, and ironing effect is more preferable, as a result, sets the ratio of semi-minor axis length in the section oval orifice 11a 1.5≤a/b≤2.5 are set to, so that the ironing efficiency of ironing apparatus is higher, ironing effect is more preferable.

Effective ironing region transverse and longitudinal ratio of the spray orifice of table 5.a/b=1

It further, is c, and 2mm with the diameter of a circle length of the area equation in the section the spray orifice (11a, 11b, 11c) ≤c≤6mm.In the present embodiment, as shown in table 6, it is respectively the spray orifice of 2mm and 6mm that simulation ironing experiment, which uses a/b=1, c, (11a, 11b, 11c) carries out simulation ironing, and is collected into corresponding effectively ironing area and temperature of zero dimension.
