Description

Apparatus for smoothing clothes

The innovation relates to a device for smoothing items of clothing according to the preamble of the claim 1.

In a known device according to the preamble of claim 1 (US-PS 3,257,739) the steam is after the heat exchanger, but in front of the turbine (fan), by means of a spray device freely into the turbine there Hot air flow sprayed. The steam-containing hot air flows generated in this way are below the turbine Interposition of a supply channel and an air distribution chamber arranged below the treatment chamber moved vertically from bottom to top through the treatment chamber. The steam gets the clothes thus supplied together with the hot air in a largely relaxed form and only in this. However, this is the case with today's multitude of fabric qualities from which the garments are made are, at least not always beneficial. This is, for example, often the warming of the garments insufficient or only given in sufficient form in a relatively long treatment chamber.

In order to improve the treatment effect in the Treatment of garments with changing fabric qualities has mar. already proposed (DE-OS 3 019 243), the steam is arranged in front of the air distribution chamber above the garment conveying path Spray hot air nozzles vertically downwards towards the hot air nozzles. The steam-containing

Hot air and largely relaxed steam or "gently" treated and only then, namely in the second treatment zone, using hot air and largely non-relaxed steam or with "concentrated force" are treated, however the "concentrated force" in the present case as a result of the direct spraying of the garments with Steam, within the hot air flow, is greater than in the prior art (DE-OS 3,019,243). The "soft power principle" leads like experiments has shown inevitably to a not insignificant energy saving.

Claim 2 contains advantageous details of the Anordjg tion of the steam spray tubes in the second treatment zone.

The device shown in FIGS. 1 to 3 initially consists of the tunnel-shaped treatment canister 11 _{s which is subdivided into the treatment zones A, B and C} Both-ended extensions 12, 13 and the transport device 14, for promoting the hanging on hangers 15 Garments 10 through the treatment chamber 11 and the extensions 12,13 of the same. The clothes 10 are in the transverse position by the transport device 14 to the conveying direction of the same (arrow 16) continuously conveyed through the treatment chamber 11.

To generate and guide the hot air streams,

arranges a turbine 17 (fan), a heat exchanger 18, an air distribution chamber arranged above the treatment chamber 11 19, an air collecting chamber 20 arranged under the treatment chamber 11 with a cover in the form of a Sieves 21 and air ducts 22 to 30 with throttle valves 31 to 34 and 43. The throttle valves 31 to 34 and 43 are movable in the direction of the double arrows drawn in these by means of elements not shown. Of the Air duct 24 leading from the heat exchanger 18 to the treatment chamber 11 and the upper air distribution chamber 19 are subdivided by means of baffles 35 to 37 for the purpose of better distribution and guidance of the hot air. Air duct 24 and air distribution chamber 19 partially merge into one another. The aforementioned sieve 21 and another, A sieve 42 arranged in front of the heat exchanger 18 also serves to filter out the during treatment of the garments 10 accruing lint from the circulating hot air streams.

To supply the steam, steam spray ^{pipes 38, 39 are arranged in the treatment zone n} A ^{n in} such a way that the steam above the treatment chamber 11 is freely sprayed into the hot air flow there (steam spray pipes 38), in the treatment zone "B" in such a way that the steam inside the treatment chamber 11 and immediately above the garments conveying path is sprayed vertically in the direction of the garments 10 (steam spray tubes 39). The two steam spray tubes 38 are arranged in the air duct 24 or in the air distribution chamber 19 transversely to the direction of flow of the hot air. The steam spray pipes 39 are arranged directly above the transport device 14. Further steam spray pipes or the like can if necessary - in the area of the upper, roof-like

Formation of the treatment chamber 11 are arranged. Pie dan steam generating units, as well as the lines and Fittings for supplying and controlling the supply of the same to the steam spray pipes 38,39 »are in the drawings" not shown because it is known per se.

The mixture streams consisting of hot air and steam are circulating by means of the devices and parts mentioned guided in the direction of shown in the figures

Single arrows without reference symbols. Fresh air is added to the mixture flows when the throttle valve is in the appropriate position 34 supplied through the air duct 23, that is to say in the direction of circulation of the mixture flows according to the handling I treatment chamber 11, as well as in front of the turbine 17 and the heat | exchanger 18.

vertical direction, like that through the $

Treatment chamber 11 guided mixture flows. After flowing through the sieve 21, all of these mixed flows become brought together again in the air collecting chamber 20 and then brought into circulation again by means of the turbine 17. 5

The device has all other facilities and parts necessary to operate the same, such as an electrical control device for controlling temperature and humidity the hot air streams containing steam.

The device works as follows: The clothes hanging on hangers 15 10 in

In the form of gowns, an operator (not shown) at the operator-side end of the extension 12 of the treatment chamber 11 is suspended in the transport device 14 and from this in a transverse position to the conveying direction of the same (arrow 16) continuously through the Extension 12, the treatment chamber 11 and the extension 13 promoted. Happen during this promotion the clothing pieces 10, the hot air locks 40, 41 arranged in the extensions 12, 13 of the treatment chamber 11, whereby these are pre- or post-treated. Both these Pre- and post-treatment, as well as the actual treatment of the items of clothing 10 in the treatment zones A, B and C of the treatment chamber 11, takes place by means of vertical from top to bottom of the garments 10 passed hot air streams. The hot air flows are Rich in the treatment zones A and B steam is supplied. The form of the explained in the description of the device Steam delivery causes the garments 10 in the treatment zone A by means of hot air and as far as possible

relaxed steam or "gently" treated and in the treatment zone B by means of hot air and largely non-relaxed steam or with "concentrated force". In of the treatment zone A, steam and hot air already form in themselves when they strike the items of clothing 10 homogeneous mixture. In treatment zone B, steam and hot air meet, at least in the upper garment area, still largely unmixed on the garments The steam flow is indeed incorporated into the hot air flow embeds, the kinetic energy of the steam is however when they hit the garments, they are still largely present or have not been absorbed in the hot air flow. In treatment zone C, the Garments 10 - when continuously operating the

Device - by means of which the treatment zones A and B

leaving, when passing through the heat exchanger 18, treated steam-containing hot air streams, however without further steam supply to these, i.e. by means of relatively dry hot air. Hit the same, different Relatively dry hot air, the garments 10 are post-treated as they pass the hot air lock 41 located on the outlet side of the treatment chamber 11 in the extension 13 of the same. In contrast, the pretreatment of the garments 10 takes place at the Pasr Sizing the warm air lock 40 located in the entrance-side extension 12 by means of relatively moist hot air, because the steam-containing hot air flows passed through the warm air lock 40 have not previously been passed through the heat exchanger 18 again. at In devices with a relatively long treatment zone B, the steam spray takes place depressively by means of the steam spray tubes 39, in the conveying direction of the items of clothing 10 seen (arrow 16).

Due to the arrangement of the hot air locks 40, 41 and the form of the supply of fresh air and the discharge of the exhaust air as explained in the description of the device it is ensured that through the inlet and outlet openings of the treatment chamber 11 no fresh or room air in this chamber can flow. It is sucked into the Treatment chamber 11 is only part of the mixed flows forming the hot air locks 40, 41. Furthermore can prevent any supply of fresh air and / or discharge of air by closing the throttle valves 34, 43 , for example when the treatment chamber 11 is heated up. A further development of the extensions 12, 13 in the sense of DE patent 2,827,433 is advantageous.
