 The ironing device comprises a holder 1 (Fig. 1) in the form of two parallel longitudinal side walls 2 and at least one heated roller 3 and moisturizing means 4 mounted therein, including at least one additional roller 5, a container 6 for the moisturizing agent 7 and the endless belt element 8, covering the heated roller 3 and the secondary roller 5. The endless belt element 8 is made of a heat-resistant inert absorbent material, for example, from a drying web. The heated roller 3 (Figs. 1, 2) is designed to exert the required pressure on the smoothed textile material and to exert a temperature effect on it. It is made of heat-conducting material (stainless steel) in the form of a rigid. Hollow. cylinder, electrically heated inside. The roller 3 is heated by the heating element 9 located therein, made in the form of an axial linear element (Fig. 1), for example a ceramic tube with a nichrome electric coil wound on it, or a surface heater (Fig. 2) on the inner cylindrical surface of the heated roller. In order to reduce heat loss to the environment above the heated roller 3 (Fig. 1, 2), a cylindrical heat radiation reflector 10 mounted on the holder 1, made, for example, of aluminum foil and concentrating the scattered infrared radiation flux on the outer surface of the heated roller 3, is coaxially mounted to it; with a thermal insulation layer (not shown) located above it to maintain the temperature of the working surface of the roller 3 within predetermined limits. Install on the surface of the heat reflector 10

A temperature sensor (not shown) is connected to the temperature controller (not shown). To create a constant tension of the endless tape element 8 (Fig. 1)

the device includes a means for tensioning it, made, for example, in the form of a springing device (Fig. 3) of the axis 11 of the additional roller 5 .. The springing device of the axis 11, in particular, includes

a strip elastic element 12 having folds 13 at its ends. The elastic element 12 is mounted on the inner surface of the longitudinal side wall 2 of the holder 1 so that each of its two

5 end sections interacts with one of the two fixed bearings 14. And its middle section interacts with a sliding bearing 15 mounted for movement along the groove 16 in the side

0 to the wall 2 of the holder 1. The elastic element 12 may be different, for example in the form of a zigzag ribbon. . Means for tensioning the tape endless element 8 {FIG. 1) provides a uniform, without folds, shape

5 tape 8 and its good adhesion to the heated roller 3.

The holder 1 is equipped with a handle 17 with a push button switch 18 of the heating element 9.

0 The tape endless element 8 (Fig. 2) is in communication with a container 6 for a moisturizing agent (water) 7. The container 6 is non-spillable and has a hole with a plug (not shown) for draining unused

5 agent 7, Capacity 6 (Fig. 1, 2) for the moisturizing agent 7 is installed in the holder 1 with the ability to adjust the position of its bottom 19 relative to the infinite flexible element 8. For this, the capacity 6

0 is fixed on a slider 20, mounted with the possibility of reciprocating movement along the longitudinal groove 16, made in each side wall 2 of the holder 1, and friction locking

5 in it.

The moisturizing means 4 (Fig. 1) according to the first embodiment are provided with a guide roller 21 located in the container b for the moisturizing agent 7 and

0 endless element 22 .. covering guide 21 and additional 5 rollers. The endless element 22 is located inside the main endless element 8 and is installed with the possibility of contact with

5 him.

The moisturizing means 4 (Fig. 2) according to the second embodiment also includes a guide roller 21 of the endless tape member 8 located in the container 6 for the moisturizing agent 7. The operation of the ironing device is as follows.

The operation of the device for the heat treatment of textile material is preceded by preparatory operations. Before starting work, fill the container 6 with a moisturizing agent 7. Set the required ironing temperature on a temperature regulator (not shown). The ironing device is connected via a cord to a source of electricity (to the mains). Using the push-button switch 1-8, power is supplied to the heating element 9. The device is ready for operation.

Ironing of textile products is carried out by the device as follows. The textile product to be processed is laid on the surface of the ironing table. The contractor brings the device to the textile material, places it on the smoothed area of the fabric, bringing into contact with the material the forming of the heated roller 3, and begin to move the device along the fabric; progressively or reciprocally, rolling on it with a heated roller 3. The ironing zone is formed by the contact area of the roller 3 and the ironing table. Due to the soft coating of the heated roller 3 with the endless tape element 8 and due to the presence of the tension elements 5, 12, 14, the tape 8 is in continuous and tight contact with the material in the ironing zone. The tension elements 5, 12, 14, in addition, align the fabric of the endless tape element 8, preventing the formation of wrinkles on it, leading to marriage in operation. When the heated roller 3 is rolled along a fabric spread along its length, each fabric element, falling into the contact zone with it, experiences compressive (smoothing) loads, which are removed after the passage of the roller 3. The process of wet-heat treatment of the fabric, in addition to the stage of its deformation, includes the subsequent stage of fixing the resulting deformation. A prerequisite for maintaining the deformation of the tissue acquired under the mechanical force of the heated roller 3 is the preliminary plasticization of it with water vapor and the subsequent removal of the introduced moisture by evaporation. The moisturizing agent 7 to be vaporized is supplied from the container 6 to the hygroscopic endless element 22 wetted by it (Fig. 1) or directly to the endless tape element 8 (Fig. 2) enveloping the guide roller 21. The moisturizing agent 7 spreads along the endless tape elements 8, 22 due to capillary pressure. The liquid 7 from the tank 6 continuously feeds on all new sections of the moving belt element 5 8, 22. In the first embodiment of the device (Fig. 1), the wet endless element 22 is continuously in contact with the absorbent belt element 8. transmitted to it by capillary pressure

0 part of its moisturizing agent. How in

a first embodiment of the device,

so in the second, the amount of moisture absorbed. by tape element 8, constantly and

quite enough for steamed tissue.

5 The tape element 8 captures the moisturizing agent 7 and transfers it to the ironing area. In the process of ironing, the heated roller 3 is rolled over the fabric to be smoothed. The moisture transferred by the sections of the hygroscopic tape element 8, upon contacting the sections with the heated roller 3 and absorbing heat from it, evaporates and prepares the fabric to form, and the dehydrated section

5 of the ribbon element 8 is again ready for the absorption of moisture from the reservoir b for the moisturizing agent. As steam penetrates into the fabric to be treated, all the necessary moisture-thermal effects are carried out. The moisture-compressing force of the roller 3 is accompanied by a small migration of moisture absorbed by the fabric from the contact line of the roller with the fabric forward along the movement of the device, which improves the wetting of the area of the fabric being smoothed at any given time. Moisture does not spread outside the area that is being smoothed out at this time, since the capillary velocity

The distribution of water in the fabric being smoothed is substantially lower than the translational speed of the heated roller 3.

During ironing, the heat flux from

5 of the heating element 9 is absorbed by the inner surface of the hollow heated roller 3 and heats it. The speed of heating of the roller 3 is ensured by its small volume, low heat capacity and

0 high thermal conductivity of the material, and the required uniformity of the temperature field of the ironing zone is ensured, - in addition to the usual thermal control, continuous interchangeability of interacting

5 with fabric portions of the working surface of a roller 3 rotating about its axis. Throughout the entire area of contact of the heated roller 3 with the tape element 8, the heat, the accumulation of the roller 3, is transferred to the tape element 8, a moisturizing agent

from which it evaporates, draining the element 8, and penetrates into the smooth fabric. Saturated water vapor penetrates into the finest porous structure of the fibers and threads of the fabric. Portions of steam in contact with the fabric being treated, the temperature of which is lower than the vapor condensation temperature, condenses, evenly moistening and warming the fabric throughout its volume. In this case, steam is first exposed to each smoothed fabric section, and then the mechanical pressure of the heated roller 3. The thermal radiation of the heated roller 3 in the direction from the ironed fabric is again directed by the infrared radiation reflector 10 to the roller 3 and thus disposed of. Moisture absorbed by the fabric, when it is subsequently heated by the heated roller 3 in contact with it through the endless belt element 8, is evaporated and removed outside the working area of the device, thereby achieving a completely fixed shape of the smoothed fabric, which is retained after cooling. If you need to iron the fabric without wetting it, a container 6 for moisturizing

Agent 7 is lowered to its lowest position by moving the slider 20 down along the longitudinal groove 16. In this case, the guide roller 21 is above the level of the moisturizing agent 7 and the endless element 22 is not wetted by it. At the end of the ironing process, the heating element 9 is disconnected from the electrical network, and the ironed fabric is removed from the ironing table.

The application of the invention allows, due to the vertical position of the handle of the device, to create great convenience in work,

made a roller pressure on the smoothed fabric at the natural (not inverted) position of the wrist. In addition, stabilization of the amount of moisturizing agent supplied to it for forming the fabric, creation of a more intense pressure of the surface of the heated roller on the fabric, and minimization of heat loss to the environment expand the technological capabilities of the device.
