Definitions
- the invention relates to an iron comprising a housing, a heatable soleplate and means for generating very fine liquid droplets to be expelled from at least one discharge opening of the iron, said means comprising at least one air passage for pressurized air supply and at least one liquid passage for pressurized liquid supply, said air passage and said liquid passage coirimuriicating with each other for mixing air and liquid, said mixture of air and liquid being supplied to the discharge opening.
- mist for moistening the fabric.
- the advantage of mist is that the droplets of mist can better moisturize the fibers than the droplets of spray as referred to hereinbefore.
- the size of the droplets of mist is 10-200 ⁇ m.
- the mist existing of very fine droplets, can be expelled either via one or more nozzles at the front and/or sides of an iron or via an opening in the soleplate.
- irons using a spray of mist are described, for example, in US 6035563 in which mist is generated by means of a piezo element, in US 6009645 or US 2762143 in which mist is generated by mixing water and steam, in FR 2764912 in which a flow of hot air is introduced into a spray of water, or in GB 764205 in which a flow of pressurized water and a flow of pressurized air are mixed, the latter being referred to in the opening paragraph hereof.
- iron water supply tubes extends alongside air pressure supply tubes which are soldered or otherwise suitable united against the water supply tubes. Between the water and air tubes restricted orifices are provided which communicate the interiors of the tubes.
- It is an object of the invention is to improve the generation of fine droplets of liquid to be expelled from a discharge opening of the iron.
- this object is achieved in that an outlet of the liquid passage ends into the air passage upstream of the discharge opening to introduce liquid into the air passage and an o ⁇ tlet of the air passage is provided with a nozzle having said discharge opening.
- liquid is introduced into the air passage.
- the air passage is the main passage and provided with the nozzle.
- a desired spray of very fine liquid droplets can easy be obtained by dosing a small amount of liquid into the air passage.
- the iron comprises a liquid reservoir and an electric pump for generating a pressurized flow of liquid in said liquid passage.
- the source for generating an air flow could also be located outside the housing, similar to liquid source as described hereinbefore, however in a preferred embodiment the iron comprises an electric air pump for generating a pressurized air flow in said air passage.
- the advantage of using electric pumps for air and liquid is that a continuous and steady flow of very fine liquid droplets (mist) is obtained. With the handpump system of GB 764205 this is not possible.
- the size as well as the delivery of the fine liquid droplets can be adjusted.
- the flow rate is variable between 0-30 g/min., preferably between 5-15 g/min.
- the size of the droplets is between 50-150 ⁇ m and a delivery between 5-15 g/min. This leads to a moisture amount of 10-15% (% of moisture weight to fabric weight) giving an excellent wrinkle removing result.
- the iron comprises a flow divider having one inlet for pressurized air, a plurality of outlet passages for pressurized air, one inlet for pressurized liquid and a plurality of outlet passages for the mixture of liquid and air, each outlet passage for the mixture of liquid ending into a respective outlet passage for pressurized air. In this manner the iron comprises a plurality of nozzles for uniform spraying fine liquid droplets on the fabric.
- the liquid can be a mixture of water and an additive liquid.
- Additives can be used to improve for instance the gliding performance or the wrinkling resistance.
- the additive liquid can be accommodated in a reservoir, for instance a removable cartridge, separate from a water reservoir.
- Fig.1 is a diagrammatic cross-sectional view of a first embodiment of an iron
- Fig.2 is a diagrammatic cross-sectional view of a second embodiment of an iron
- Fig.3 is a bottom view of the iron of Fig.2, Fig.4a,b,c,d show a flow divider, Fig.5a,b,c show several examples of cyclone nozzles.
- the first embodiment of an iron shown in Fig.l, has a housing 1, the open lower side thereof being covered by a heatable structure comprising a die casted block 2 in which a heating element 3 is incorporated and a soleplate 4 which is secured to the die casted block.
- a water reservoir 5 Inside the housing a water reservoir 5, an electric air pump 6 and an electric water pump 7 are located.
- An air passage 8 connects the air pump 6 with a discharge opening 9 of a nozzle 10.
- a mist chamber 11 is provided in the casted block 2 and the soleplate 4 a mist chamber 11 is provided in this mist chamber.
- a water supply channel 12 connects the water reservoir 5 with the electric water pump 7.
- a water passage 13 connects the outlet of the water pump 7 with the air passage 8 at a junction 14 upstream of the nozzle 10.
- the air pump creates an airflow through the air passage 8 toward the nozzle 10.
- the water pump 7 creates a small water flow through the water passage 13.
- a small amount of water is introduced into the air passage 8.
- the air with a small amount of water flows to the discharge opening 9 of the nozzle 10.
- a spray 15 of fine water droplets is generated at the discharge opening.
- the spray of droplets discharges into the mist chamber 11.
- the discharge opening of the nozzle is preferably 0.3-0.6 mm.
- the air pressure is in the range of 0.15-0.5 bar.
- the mist chamber 11 is heated up to at least 100°C to prevent dripping caused by droplet accumulated on the wall of the mist chamber.
- the iron comprises a reservoir 16 containing an additive liquid 17.
- An outlet passage 18 of the additive reservoir is connected to the water supply channel 12 of the water reservoir 5 so as to form one single outlet passage 19 for the mixture of additive liquid and water (diluted additive) to the electric liquid pump 7.
- the outlet passage 18 may further comprise an adjustable valve 20 to control the additive liquid flow and thus the degree of dilution of the liquid. If the valve 20 is shut off only a spray of fine water droplets is obtained.
- the additive reservoir 16 is a removable cartridge.
- the iron further comprises a control unit 21 to control the power of the pumps 6 and 7 and thereby the flow and pressure in the passages 8 and 13 respectively.
- the control unit may also control the valve 20 and thus the flow of the additive liquid.
- a second embodiment of an iron, shown in Fig.2, in which similar parts are indicated with the same reference number as in Fig.l, comprises a flow divider 22, details of which are shown in Fig.4a,b,c,d.
- the flow divider comprises a housing 23 having a central inlet air passage 8 for pressurized air, a plurality of outlet passages 8a for pressurized air, a central inlet passage 13 for liquid (pure water or water diluted with an additive liquid) and a plurality of outlet passages 13a for said pressurized liquid.
- Each outlet passage 13a for pressurized liquid ends into a respective outlet passage 8a for pressurized air at the junction 14a.
- the shown flow divider 22 has 5 outlet passages 8a each ending into a nozzle 10a, so that at 5 positions of the soleplate mist is generated (see Fig.3), thereby obtaining a better uniform moistening of the fabric.
- Good results with a continuous and steady flow of mist between 5-15 g min. are obtained with an iron having 5 of such mist spray nozzles with the following data: For operating air pressure: 0.15-0.5 bar:
- the nozzles 10a are preferably of the cone type in order to create a cone type mist pattern 15.
- Fig.5a,b,c several cone type nozzles are shown.
- the nozzle is provided with tangential holes or slots 24, in Fig.5b there are axial helical slots 25 and in Fig.5c the slots 26 extends conical.
