Ironing machine is mainly used for household purposes

The invention relates to an ironing machine} which essentially to be used in the household, and which consists of a motor-driven ironing roller and an iron, between which the material to be ironed is ironed.

Known machines of this design either only have an extremely limited area of application or are there consist of many working machine elements, expensive to manufacture, heavy weight and bulky shape make it difficult Change of location and storage of the machine in the house *

TELEPHONE: 0184057

The present invention, which significantly reduces the number of machine elements, results in a lightweight, space-consuming one and cheap machine. The invention not only allows all of the previously known and desired movement- schema, but extends and simplifies it even more «

The machine according to the invention consists of an expedient Textile-covered roller that presses itself down against a hot iron, not just by force, with or without rotation can, but can also be stopped and started in this position * Of course, there is also an arrangement possible with the roller firmly attached, and the iron can be swiveled against the roller. The item to be ironed is inserted between the roller and iron, where it is not only against the hot iron ^ pressed, but also by turning the roller is pulled over the iron and then, once ironed, it falls down onto the collecting table *

This ironing principle is already known, but so far the motor and gear were outside the moving roller Rotation via a large number of gears up to the pivot axis of the roller and then via a lever that supports the roller up to the roller *

In contrast, the present invention is primarily characterized in that the motor, possibly including a gear, a clutch and a pump for generating the pressure required for ironing, is arranged inside the rotatable ironing roller which can be pivoted towards the iron.

The invention is illustrated below, with reference to the beige ~ Reference is made to the accompanying drawings which illustrate, by way of example, an embodiment of the invention. Fig «1 is a section through the ironing roller with the two levers and the lever shaft carrying them. Fig. 2 shows an end view of the ironing machine ·

In the illustrated embodiment, the ironing machine consists of a hollow ironing roller 1, suitably covered with textile, which is supported on axle journals 2 and 3. The axle journals sit on levers k or «5 * which are firmly connected to one another by a skin 6«. A further frame 9 is attached to the table 8 and carries a concave-shaped iron 10, which in turn serves as a support for an insert table 11. A pressure cell or a pressure cylinder 12 is also mounted on the table 8, with the help of which the ironing roller 1 is pressed against the iron 10, as well as a return spring 13 * which guides the ironing roller 1 away from the iron; when the pressure cylinder 12 stops working _s and a distribution valve 14, the function of which will be described in more detail below. The ironing roller 1 is driven by a motor 15s arranged in it, which at one end drives a toothed wheel 16 which runs free when starting and which is provided with a flange 17, with the inner surface of which a pneumatic coupling in the illustrated embodiment cooperates. The coupling consists of a wheel 18 provided with internal channels and its outer circumference

by, a stretchable membrane 19 is covered, which is pressed against the inner surface of the flange I7 when compressed air is supplied »The wheel 18 is mounted on a shaft 20, from which the force is transmitted via gears 21, 22 and 23 and also as an end wall Serving gear 2h is transferred to the ironing roller. The other end of the motor drives a diaphragm pump with the help of an eccentric 25, which supplies compressed air to a pressure bell or a pressure accumulator 28 via a line 27 and a non-return valve (not shown) the likewise hollow lever 5 is passed down to the distribution valve mounted on the table 8, from which a line 30 runs the same way back into the ironing roller. With the help of line 30, compressed air is fed to clutch I7-19. From diverting 14 compressed air can continue through a line 3I to the impression cylinder 12 be passed * The distribution valve 14 is constructed such that it is the roller 1 against the iron 10 presses down in performing in a first operating position by compressed air xvird passed to the impression cylinder 12 ,, the while the shaft 6 and thereby the levers 4 and 5, which carry the ironing roller 1, rotates via a lever 32, and when guided into a second working position, the roller 1 is set in rotation by compressed air being passed through the line 3 ° zxxr coupling 17-19 so that the membrane I9 expands and presses against the flange I7. When you switch from the second to the first working position, the compressed air is released from the coupling I7-19 and the roller stops rotating. When the coupling slide of the distribution valve is returned further, the pressure goes out of the pressure cylinder 12 »the roller is in its position by the return spring I3

upper position turned back, and the entire process can be repeated «From the memory 28 a line 33 runs to a relief valve "} h , on which a membrane 35 is actuated when the desired pressure in the pressure accumulator 28 is reached that a shaft 36 counteracts the action of a Spring 37 is displaced and pushes up a ball 38 which enables the pump to work without increasing the pressure any further.

The two journals 2 and 3 are in the roller 1 together connected by a support system 39 that supports the motor I5 and the rest The parts mounted in the roller carry «The electric current is fed into the engine through lines 40 on the same ¥ eg as the air lines 29 and 30.

In addition to the advantages evident from the above, the arrangement according to the invention brings about further advantages *, Ua _# the roller pressure remains constant, regardless of the thickness of the ironed item have to be. In the arrangement according to the invention, the roller is released from the hot iron by releasing the compressed air in the usual way with the aid of the distribution valve. If, as in the example shown, an air pump can _be} compared to previously known fully mechanized Bügelmaschinenj the engine power to about one-third decrease "In the arrangement according to the invention namely the engine can work all the time in setting up the necessary for ironing pressure"

In the case of mechanical operation, on the other hand, the motor must
carry out a greater part of his work within a very short time »

The invention is not limited to the embodiment described above limited, but can be modified in its individual parts within the scope of the following safety claims. It e.g. it is not necessary to generate the pressure on a pneumatic pan, it can also be used, for example. hydraulic or electromagnetic to be effected «
