As shown in figures 3 and 8, diffuser casing 7 allows to be predominantly located in the preceding part of cover 2, in the cold-zone domain of ironing surface In first group 21 of steam outlet ports 20 supply steam, and allow in the thermal region of ironing surface, be arranged in cover 2 Second group 22 of steam outlet ports 20 in part supply steam afterwards.First group 21 of steam outlet ports 20 are mainly directly arranged On the opposite of diffuser casing 7, so that the steam spread by this some holes is not contacted with heating bottom plate 3, and it is being diffused into the outer of cover 2 Before portion, do not heated by heating bottom plate 3.

Preferably, first group 21 of steam outlet ports 20 are distributed in the whole surface of the cover 2 covered by cavity 30, so as to Steam is spread on the width corresponding at least 65% width of cover 2.

Second group 22 of the steam outlet ports 20 are indirect by distribution channel 47 being arranged on the rear part of cover 2 Ground supplies, and at second group 22 of the steam outlet ports 20, steam is heated before the outside for being diffused into cover 2.

The work of this ironing equipment and the advantage that this structural belt comes will now be described.

When equipment starts, case 102 heated and it includes water be heated to boiling, the pressure generated by case 102 Under steam pass through steam lead 105 towards flatiron 1 transmit.When steam is transmitted through conduit 105, the temperature of steam drops It is low so that the condensate liquid formed in the steam stream for reaching flatiron 1.

When user drives pin key 10 to discharge the steam under the pressure for including in case 102, if these are condensed The sufficiently large water slug to be formed in steam lead 105 of liquid, then the water pushed fiercely across steam-return line, especially At injection zone 45.These are collected in by its inertia in first bag of 45B by the water droplet major part that steam stream pushes, water quilt It is stored in first bag of 45B gradually to be evaporated, and steam stream continues its road by laterally by entrance 43D is discharged Diameter.

Anyway, it is understood that there may be water droplet driven by steam stream in the first conduit 43A of device, later along centrifugation Partial exterior side wall 5 flows and reaches air deflector 5B, and at air deflector 5B, water droplet direction faces the side wall 8 of air deflector 5B It is projected onto in vaporization chamber 43.Water droplet is then moved along the curve of parabola type in vaporization chamber 43, this dotted arrow such as Fig. 4 Shown, until hitting side wall 8, at the side wall 8, water droplet is brought in second bag of 43E, and steam can be directly by being arranged in Side opening 43C at the top of vaporization chamber 43 and be directly discharged.

When being based upon when the flow rule of steam stream between base portion 100 and flatiron 1, the condensate liquid carried by steam is more Move less and in the form of the water droplet of separation or in the form of liquid film, the liquid film along evaporation circuit wall by steam It is moved under the action of raw driving force of miscarrying.

Seamed edge 80 is reached along the liquid film that side wall 8 flows in the first conduit 43A, vortex flow is formed in the seamed edge 80 Place, the vortex flow allow film under gravity in the bottom of vaporization chamber 43 along with the decline of the speed of steam stream In, in the rear flow of step 48.

The region being located at the downstream of air deflector 5B is reached along the liquid film that side wall 5 flows in the first conduit 43A, in rib The opposite on side 80, wherein the speed of steam stream declines because of the suddenly change in direction so that film passes through gravity flowing to vaporization chamber Bottom in, at the downstream of step 48.

Liquid film flows on lid 6, along the top of vaporization chamber 43, and the liquid film is guided by rib 62, until reaching shape At in second bag of 43E in mild region, second bag of 43E is far from main steam stream, at second bag of 43E, water droplet It can be by gravity flowing to the bottom of vaporization chamber 43.

After the recycling of the condensate liquid carried by steam stream and after the recycling of liquid film, in vaporization chamber 43 It is gradually evaporated by the heat of bottom conductive of the water accumulated in bottom by being evaporated room 43.

The energy consumed for evaporating the water helps to reduce the temperature of vaporization chamber 43, and therefore avoids vaporization chamber 43 It is not heated excessively by hot-fluid, when the preset temperature of first resistor 31 is more than 200 DEG C, hot-fluid is generated by first resistor 31.

This construction of vaporization chamber 43 allows to obtain the steam only loaded with Mini-type water drop in the exit of vaporization chamber 43, The steam passes through channel 46 to be released in the diffuser casing 7 of the top for the preceding part for being arranged in cover 2.

Thermal region of the diffuser casing 7 far from cover 2, the steam at diffuser casing 7 are diffused through first group 21 of steam Delivery outlet 20, with higher humidity, that is to say, that there is the miniature water droplet being deposited on the fabric being ironed Load.

Therefore it is obtained to the good humidification of clothing by steam, the steam is from being arranged in the preceding part of cover 2 Steam outlet ports 20.

In particular, this construction allows the B points in the cold-zone domain positioned at ironing surface and the thermal region positioned at ironing surface In A points between establish big thermal gradient, this is because geometry allow by hot-fluid be limited in cover 2 center and cover 2 before Between part, the heating of first resistor 31 is directly born in the center of the cover 2.

Therefore, the temperature of bottom plate 3 is heated, and therefore the temperature of the rear part of ironing surface can be adjusted to more than 240 DEG C Preset temperature near, and the temperature being maintained at simultaneously in the preceding part of ironing surface, and especially near B points, by temperature It is maintained at 100 DEG C or so.

In addition, the raising for gradually leading to the temperature of vaporization chamber 43 in order to avoid the energy discharged by the rear part of bottom plate 3 More than 130 DEG C, electronic card 108 can advantageously comprise the program of control pump 104 and electric valve 107, so as to regularly will be a small amount of Water is injected into steam lead 105.

In fact, the water being injected into steam lead 105 is driven by steam stream until vaporization chamber 43, in the vaporization chamber 43 Place, these water droplets specially imported will be evaporated and therefore generate the decline of the temperature of vaporization chamber 43.

When the pin key 10 of user's drive control electric valve 102A discharges steam to be passed through steam lead 105, water exists Controlled injection in steam lead 105 can be realized in a manner of system.

Therefore, as shown in figure 9, electronic card 18 can control the opening of electric valve 107 and opening for pump 104 at regular intervals It is dynamic, so that when electric valve 102A is opened, the water for coming from pump 104 is guided towards steam lead 105.For example, working as pushpin When key 10, during the entire opening stage of electric valve 102A, the 100ms that is activated is pumped on the period of 500ms, relative to pump 104 activation, electric valve 107 is to be, for example, the stand-by period of 100ms to be activated and deactivate.

In implementing variation example, controlled injection of the water in steam lead 105 can be with the default temperature of first resistor 31 Degree is that condition carries out.As an example, the controlled injection of water will only be more than for example, in the preset temperature of first resistor 31 Just implement when 200 DEG C of certain threshold value.

It, can be according to passing through by being injected into steam lead 105 for a small amount of water rules in another implementation variation example Sensor measurement to the actual temperature of vaporization chamber 43 realize that the amount of the water injected is when vaporization chamber 43 in a controlled manner It is more when temperature is higher.

Certainly, the preset temperature of the first thermostat is relatively low, and close to 100 DEG C, the presence of second resistance 41 passes through with it The adjusting of second thermostat 60 allows in the temperature that the temperature by vaporization chamber 43 is kept closer to 105 DEG C, to allow by The condensate liquid collected in vaporization chamber gradually evaporates.

Therefore, the flatiron 1 so realized allows the steam by first group 21 of the diffusion high humility of steam outlet ports 20, but The steam does not have condensate liquid.Therefore, the steam rapid condensation discharged by hole 20 allows to obtain in the thickness of fabric Better flatiron performance, the condensation in the fabric are pressed near first group 21 of steam outlet ports 20 close to 100 DEG C The low temperature for scalding surface promotes, and the low temperature avoids excessively heating fabric.

Since the heat distribution and steam are in the diffusion of the temperature close to condensation, the fabric of higher ironing temperature is needed Smoothing wrinkle performance is enhanced, the fabric such as flax or cotton fabric.

In addition, when flatiron is moved towards front, the steam outlet ports 20 for being ironed the cold-zone domain on surface before moisten Fabric extent by the rear partially dried of the ironing surface with higher temperature.

When the preset temperature of ironing surface is about 100 DEG C, the temperature for covering 2 preceding part is remained above 90 DEG C, this be because For by with the heating radiation of front end 4 of bottom plate, the convection current by being present in the steam in cavity 30 or by with around sky The conduction of the part of the heating bottom plate 3 of chamber 30 and the heat exchange established cause, this be enough to avoid steam be directly condensate on cover 2 and Laundry wet is made by capillary phenomenon formation simultaneously by leads to long drying time.

Finally, the steam discharged by second group 22 of steam outlet ports 20 has the advantage that than being discharged by first group 21 Steam humidity it is lower, this is because when steam passes through the distribution channel of heating bottom plate 3 and while spreading is heated again causes, So that steam does not interfere the drying of the rear part of clothing quilt cover 2 by the discharge of this some holes.On the contrary, when the after part for only covering 2 When being used to the specific region of ironing clothes, the presence of second group 22 of steam outlet ports 20 allows the efficiency for improving flatiron, presses Bucket 1 is only only oriented towards rear movement on the specific region of the clothing.

Certainly, the present invention be only limitted to absolutely not it is given only in an example shown in and described embodiment.Not It can be modified in the case of beyond the scope of the present invention, especially in terms of the composition of different elements or pass through technology etc. Valence is replaced.

Therefore, in unshowned implementation variation example, the cover can only include first group of steam outlet ports, and not have There are second group of steam outlet ports.

Therefore, in unshowned implementation variation example, the case for generating steam can be mounted directly in flatiron, and And/or person is made of flash evaporation room.

Therefore, in unshowned implementation variation example, heating element can be realized by the flat heating element of silk-screen printing.

Therefore, in another unshowned implementation variation example, flatiron may include collector, and the collector is relative to adding The cavity of hot bottom plate is laterally arranged.The collector realizes that the collector is included in advantageous by punching stainless steel plate The tap on first group of each steam outlet ports opposite, so that steam stream to be previously oriented towards these steam outlet ports.This Kind of collection utensil has advantages that, is further limited in steam stream and heats the heat exchange established between bottom plate, this allow into One step reduces the vapor (steam) temperature in the exit of first group of steam outlet ports, to realize to a greater degree of humidification of clothing With better flatiron performance.
