RU1839202C - Low-inertial predominantly thermoradiation iron - Google Patents

Description

made by pushing it into the sole (flush with the smooth surface), exceeding the weight of the iron.

In the following, which does not affect the integrity of the ironing sole, and therefore it may be more preferable, the sensor of the ironing object, which controls the state of the contacts of the second switch, is made in the form of two parts (components in the direction perpendicular to the sole, i.e., along the height of the iron) iron, elastically pressed one from another. This can be the handle of the iron and its lower part - the body or the handle and the sole itself.

When loaded by the user's hand, these parts come together and close the contacts, and when the load is removed, the power circuit is again broken.

The significance of the above differences of the proposed iron is due to the absence of their mention, especially in the aggregate and interconnection, in the sources of information available to the applicant.

The technical essence of the proposed highly economical and fireproof low-inertia iron, for example, with a thermo-radiation electric heater, which provides heating of the ironing object, which is effectively absorbed by thermal (in particular, infrared) radiation, freely passing through the sole transparent to it, is illustrated in FIG. 1-3.

In FIG. 1 and 2 schematically show a variant of the proposed iron, in particular light, in which the sensor of the ironing object (for example, in contact with it) is, firstly, located in front of the ironing sole and, secondly, made in the form of easily rolled in any ball directions; in FIG. 3 is a fragment of a variant of the front of a similar iron.

So, according to FIG. 1 and 2, the top of the iron is handle 1 and the bottom is body 2.

And since the illustrated iron is light, i.e. heats the ironing object 3 by the thermal (infrared) radiation of the electric heater (lamp) 4, which is effectively absorbed by the ironing object, then the ironing sole 5 is optionally transparent for the radiation of the lamp 4, to increase the efficiency equipped with a reflector (mirror layer) 6.

The lamp 4 is fixed inside the housing 2 by means of the holder terminals 7 and 8 and is installed, for example, through a deluxe plug (plug) 9.

The handle 1 and the housing 2 are fastened to each other by the protrusions 10 (on the housing) and the spring grips 11 (at the ends extending from the handle 1).

The supply voltage to the iron is supplied through the network terminals 12 and 13. When ironing (the user's hand squeezes the handle 1 and presses the iron to the ironing object 3), the electric current through the lamp-heater 4 passes along the path:

terminal 13, closed contacts 14 (movable) and 15 (fixed), controlled by a sensor (strip sensor) 16 for the presence of the user, bus 17 along the surface of the housing 2, rivet 18, closed contacts 19 (fixed) and 20 (elastic , 5 movable, made on the holder 7, the terminal-spring), the terminal-holder 7, the lamp itself 4, the terminal-holder 8, the input-rivet 21 and the second network terminal 2.

Contacts 14 and 15 form one switch with a control element - a sensor 16 for the presence of the user in the form of a console plate protruding in the front of the handle of the iron protruding from the rear of the spring plate, closing the contacts only when it is pressed against the surface of the handle.

Contacts 19 and 20 form a second switch. They are closed by the sensor 22 of the presence of the ironing object, made in the above embodiment in the form of a ball. This

0 the ball due to the elasticity of the spring terminal 20 is pressed against the seat in the sole 5 and partially (less than half a diameter) protrudes beyond its smooth surface.

When ironing, contact closure

5 is carried out by pressing the sensor strip 16 to the surface of the handle (contacts 14 and 15 are closed) and pressing the iron to the ironing object (contacts 19, 20 are closed) with a force exceeding the force of the ejecting ball 22 of the spring terminal 20.

FIG. 2 illustrates the appearance of the sole iron described above.

In FIG. Figure 3 shows a fragment of a variant of the front of a similar iron (the rear can exactly repeat the variant in Figs. 1 and 2), in which the sensor of the ironing object does not violate the sole continuity, since it is based on elastic

0 interaction in a direction perpendicular to the plane of the sole, upper and lower parts of the iron (otherwise - the handles and soles of the iron).

Here, the lower front part 23 of the handle 1 with the gripper 11 is made in the form of a spring acting on the beveled front part (inclined surface) 24 of the housing 2 in the direction 25 and providing, in the absence of extraneous (except for the dead weight of the handle 1) (towards the sole 5) the clamping of the gripper 11 to the protrusion 10 on the beveled part 24 of the housing. In this position, the contacts 20 (movable, rigidly fixed under the handle 1) and 19 (fixed, connected, as in Fig. 1, with the terminal holder 7) are open,

When ironing, they are closed, because under the influence of a hand-pressing user, the area (grip) 11 of the spring 23 slides along the inclined surface 24 of the housing 2 together with the handle. When the load (hand) is removed, the gripper 11 under the action of the spring 23 slides on the surface 24 in the opposite direction and raises the contact 19 together with the handle 1.

Thus, in both cases, the iron heats only if two obligatory conditions are fulfilled simultaneously (and regardless of spatial orientation):

squeezing the handle of the iron by the hand of the user;

pressing the sole of the iron to the ironing object with an force of at least a predetermined force (or positioning it from the ironing object at a distance of no more than a predetermined one).

The sensors for the presence of the user's hand and the ironing object can be non-contact (for example, capacitive, etc.), and the switches 14,15,19,20 are non-mechanical, for example, in the form of electronic relays, keys controlled by these sensors. However, in this case, the formation of a special supply voltage different from the mains is required.

Among the advantages of the proposed iron (in comparison with the irons according to autoswitch Ns 592895, 1155641) it should be noted its lower energy consumption, increased fire protection, all this with the simplicity of design and manufacture, with the independence of operational characteristics from orientation in space and t .P.
