DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION A tunnel finisher is provided by connecting a steam chamber and a hot air chamber in series, attaching hanger hooks at predetermined intervals to a chain conveyor provided in the upper part of both chambers, and suspending the hanger hook. The clothes are covered with a hanger and passed through a steam chamber and a hot air chamber, and the clothes are dried and finished with steam and hot air.

Such a tunnel finisher is disclosed in, for example, Japanese Patent Application Laid-Open No.
No. 127593, Japanese Utility Model Laid-Open No. 1-131499,
Various types are proposed in Japanese Utility Model Laid-Open No. 2-82295 and the like. The tunnel finisher according to each publication is the same in the basic configuration. For example, in the first publication, an opening / closing door is provided at the entrance of the steam chamber by dividing the opening and closing into a plurality of upper and lower sheets and a plurality of doors corresponding to the divided doors. A suitable amount of steam is provided by opening and closing the door according to the size of the garment and blowing out the steam from the nozzle by connecting the nozzle corresponding to each door and operating the nozzle corresponding to each door It is trying to make it.

[0003]

By the way, in the above-mentioned conventional tunnel finisher, as shown in FIG. 9, the supplied steam passes through the first solenoid valve 11 through the supply passage branched in the middle of the supply passage. The steam is branched and sent to a heater 12 (heat exchanger) for heating the chamber 3 and a separator 13 for blowing out steam from the steam chamber 2, and the steam from the separator 13 is supplied to the pressure reducing valve 14 and the solenoid valve 15. To the steam blow-out pipe 16 respectively. The solenoid valve 1
Although 1 is shown in the hot air chamber 3, it may be provided in the steam chamber 2.

[0004] However, depending on the type of boiler and the installation location, dry steam may be sent depending on the type of boiler and installation location, depending on the cleaning factory where the tunnel finisher is installed. For this reason, the steam blown out from the steam blow-out pipe will be the dry steam blown out as it is, and therefore the dry steam with little moisture is directly blown to the steam blown to the clothes, so that the wrinkles of the clothes do not grow much. There are inconveniences.

The present invention takes into account the problem of the above-mentioned conventional tunnel finisher, and devises the above-mentioned piping path without adding a new component to the conventional apparatus, thereby producing moist steam and spraying the garment. An object of the present invention is to provide a tunnel finisher capable of sufficiently extending wrinkles.

[0006]

According to the present invention, as a means for solving the above-mentioned problems, a hanger is provided on a chain conveyor provided with a steam chamber and a hot air chamber connected in series, and provided at an upper portion of each chamber. In a tunnel finisher in which a hanger is attached at a predetermined interval and a hanger is hung on the hanger hanger, clothes are put on the hanger, and the clothes are passed through each room to finish drying, the supplied steam is heated in a hot air chamber. The steam finisher was sent to a heater, and a steam path was provided so that the steam cooled and increased in humidity was blown out from a steam blowing pipe provided in a steam chamber.

[0007] According to the tunnel finisher of the present invention having such a configuration, beautiful finishing is performed by effectively removing wrinkles of clothing as described below. As the steam to be supplied to the tunnel finisher, for example, when it is very close to the steam discharge part of the boiler due to the equipment in the cleaning plant to be installed, hot dry steam may be directly supplied to the tunnel finisher.

In such a case, since the steam is dry steam, even if the steam is blown out from the steam blow-out pipe and applied to the clothes, the wetness is small and the clothes cannot be wrinkled. The steam thus produced is passed through a hot air chamber or a heating line to be cooled to a certain extent, so that the steam thereafter becomes humid steam and is blown out from a steam blowing pipe.

For this reason, in the tunnel finisher of the present invention, since the humid steam is contained in the clothes, wrinkles are naturally removed and beautiful finishing is performed.

The clothes X suspended from the hanger rack 7 via the hanger 8 move in the center of each of the rooms 2 and 3 by the chain conveyor 4.

As will be described later, the steam chamber 2 is provided with a plurality of U-shaped steam blow-out pipes provided along both sides of the inside thereof. Steam is supplied by the piping system shown. That is, the steam sent from the steam supply port 10 is mainly sent to the heater 12 (heat exchanger) via the first solenoid valve 11.

The steam that has passed through the heater 12 is sent from the end of a heating pipe system for heating pipes (copper pipes) for heating necessary portions of the steam pipe system, rails, the bottom of the steam chamber 2, and the like. The steam is combined with the incoming steam and sent to the steam separator 13. Then, the drain is separated therefrom and sent to the steam blowing pipe 16 through the pressure reducing valve 14 and the second solenoid valve 15. The steam outlet pipe 16 is provided with a number of steam outlets 16a, from which steam is blown out. The end of the steam blowing pipe 16 is closed at an end 16x. P _G is a pressure gauge.

As described above, the steam supplied from the steam supply port 10 is first sent to the heater 12 via the first solenoid valve 11. At this time, generally, the third solenoid valve 17 is closed. Even if the steam sent to the heater 12 is a high-temperature dry steam, heat exchange is performed by heating and drying the clothing passing through the heating chamber 3 there, and the temperature drops to become a humid steam.

This wet steam is sent to the steam separator 13,
The drain component contained in the wet steam is removed and the pressure reducing valve 14,
The air is sent to the steam blow-out pipe 16 through the second solenoid valve 15 and blown out from the outlet 16a to the clothes. Because of the high humidity of the steam, the wrinkles of the clothes grow well and a beautiful finish can be obtained. The garment blown with steam containing a large amount of moisture is sent to the heating chamber 3 in a state where the wrinkles are completely extended, where it is dried by the heater 12 and taken out.

Although not shown, the temperature of the steam sent to the heater 12 is checked by a temperature sensor. For example, when the temperature of the heater exceeds 105 ° C., the supply of steam is performed by the first solenoid valve. It is set so as to shut off and pass steam at 105 ° C. or lower.

Although the third solenoid valve 17 is unnecessary in principle, when the steam is blown out from the steam blow-out pipe 16, the steam pressure in the heater 12 is reduced and the third solenoid valve 17 is heated.
2, the heat temperature becomes lower. For this reason, in order to prevent the steam pressure from the heater 12 from lowering, when the pressure becomes equal to or lower than a certain pressure (for example, 1 atm), the third solenoid valve 17 is opened, and the steam from the steam supply port 10 can be passed directly to the steam separator 13. It is provided for the purpose.

Further, the second solenoid valve 15 is used to
In order to supply steam only when passing through, a valve (not shown) for detecting passage of clothing is provided so as to be opened by a signal. This prevents the steam from being wasted.
