Definitions

the invention relates to a vacuum blower for smoke channel and a sweeping method according to the preamble of the independent claims presented below.
the invention relates in particular to an arrangement to be used as an aid in sweeping, which is attached to the upper end of the smoke channel to be swept and with the swept during sweeping air and sweeping foreign substances are sucked out of the flue. Such an arrangement reduces the risk that soot and other foreign matter will spread out of the channel to be swept into the interior of the building.
the broom When cleaning the smoke channel, for example when sweeping the smoke channel, the broom triggers foreign matter, such as soot and dross, from the surfaces of the smoke channel. To be effective enough, the brush's bristles must be stiff and dense enough for brushing to be effective. Such a broom fills the smoke channel quite dense. As the dense broom moves down the smoke channel, it shifts in front of it an air pressure pulse that can cause soot and other debris to escape from the openings of the smoke channel into the interior of the building. This can be prevented by sucking negative pressure from the upper end of the smoke channel into the smoke channel during sweeping. Many arrangements are known from the prior art with which air and foreign substances released during sweeping are sucked out of the smoke channel.
DE 94 10 409 U has a device for connecting a suction device to an opening of a chimney to be cleaned.
the device essentially consists of flexible and transparent film material, has a flexible frame and is sack-like with respect to the frame to at least one side, which can be arranged below when mounting the frame on a vertical wall.
GB 672,970 discloses a device for cleaning a chimney, which device has a closure suitable for closing open chimneys.
the closure has a closable opening for the hand and arm of the chimney sweep and a second smaller opening for connecting a pipe leading to the suction device.
the pressure in the space behind the closure is kept lower than that of the atmosphere when the first opening is uncovered and in operation.
the main object of the present invention is to reduce or even eliminate the above problems encountered in the prior art.
the object of the present invention is in particular to align a vacuum blower for a smoke duct, which is reliable, easy to handle, light and small and can be arranged tightly against different smoke channels.
the object of the invention is further to improve the safety of the chimney sweep by making it easier to work in the typical difficult circumstances, such as on the roof of a building. Another task is to improve the visibility of chimney sweeps in traffic.
the vacuum blower according to the invention for smoke duct is suitable for use as an aid in the cleaning of various channels, such as air, steam and smoke channels.
a typical smoke duct vacuum blower according to the invention comprises a discharge duct having a starting end and a terminating end.
a typical smoke duct vacuum blower comprises a discharge duct having a starting end and a terminating end.
the discharge channel is connected to a blower, which sucks air and thus also foreign substances from the starting end of the discharge channel and carries it out further from the terminal end of the discharge channel.
the arrangement further comprises a motor for driving the fan and the necessary switch for the drive control of the motor and thus of the fan.
a typical discharge channel is arranged so that it passes through the plate-shaped sealing surface. In order to achieve the best possible suction performance, the starting end of the discharge channel is sealed by the sealing surface as well as possible against the exhaust duct to be exhausted.
the sealing surface is typically significantly larger than the cross section of the starting end of the discharge channel.
a typical sealing surface according to the invention consists of elastic material, such as rubber, plastic or elastomer, so that their size can be adapted to the respective smoke channel.
Elastic is understood to mean that the material is easily bendable by hand, ie deformable. Accordingly, the shape of the sealing surface can preferably be so easily redesigned that the chimney sweep can apply the arrangement with one hand even in a narrow place. It is possible, for example, that the plate-shaped sealing surface is provided with bending elements, such as grooves, depressions or joints formed therein, by bending along which the size of the sealing surface can be adapted according to the respective requirements.
the sealing surface can, of course, in and of itself consist of such a resilient material, such as thin rubber disc, that it can be bent to different shapes without special bending elements.
the elastic sealing surface according to the invention can, for example, be bent at an angle of 90 ° or even 180 ° with a radius of curvature of 1-10, 1-5 or 1-3 cm.
the plane of the sealing surface can be bent in the direction of the plane with divergent folds.
the plane of the sealing surface can be either in the direction of the blower, ie for example by bending the edges of the sealing surface on the blower assembly, or in the opposite direction, ie for example by bending the edges of the sealing surface placed on the chimney downwardly at its over the blower Extending the edge of the chimney Part, to be bent.
the elastic material of the invention is elastic enough to be recovered after use or easily restored to its original shape.
a big advantage of the elastic sealing surface is that the assembly can be tightly fitted into smoke channels of even very different sizes and shapes.
the arrangement also fits even through small openings, for example under fixed chimney hoods.
the elastic sealing surface can be easily applied relatively close to the edges of an even uneven smoke channel.
An advantage of the elastic sealing surface is that it requires little space during transport.
a passage for sweeping line is formed in the discharge channel at a distance from the opening of the starting end.
the opening of the starting end and the passage for sweeping line in the straight line are such that the drawn through the passage for sweeping lines to the plane of the sealing surface straight line through the opening of the starting end of the discharge channel.
the sweeping line passes through said passageway upon actuation of the assembly and not between the assembly and the smoke channel, as in the prior art arrangements.
the arrangement of the invention usually does not need to be moved and lifted during sweeping. When the line is between the assembly and the edge of the smoke channel, and especially when moving and lifting the assembly, the vacuum disappears easily from the smoke channel. When the leash runs through its own passage, it is not scrubbed against the usually sharp edges of the smoke channel, so it lasts longer and runs more easily in the smoke channel.
the blower is an axial blower. In that case, it takes up little space. It is possible to make the diameter of the axial fan approximately equal to the discharge channel, as part of the discharge channel or therein where it can be aligned as part of or in the exhaust duct. As a result of the fact that the discharge channel is pivoted horizontally immediately after the opening of the starting end, such a vacuum blower requires only as much space vertically as the cross section of the discharge channel or axial blower. Thus, the small arrangement can be set well in tight spaces.
the preferred vacuum blower according to the invention for smoke duct has at least one light source, such as a light-emitting diode.
the light source When the light source is made near the terminal end of the exhaust duct, the light from the light source is particularly easy to set up to clear the gas flow from the exhaust duct. It is easy to notice even in the dark whether foreign substances escape from the smoke channel. Especially when sweeping smoke channels, it is important that soot comes out of the smoke channel all the time. The exit of soot is a sign of negative pressure in the smoke channel. Without negative pressure in the flue duct, there is a great risk of foreign substances entering the interior of the building.
the light source also makes a great advantage in traffic when cycling or walking.
the light can also be switched on the way from one sweeping workstation to another. In this case, it is easier for motorists and other road users in dark weather to notice the general coloring of such black chimney sweeps.
the LED consumes little power, but its brightness is sufficient for the above purposes.
a vacuum blower 1 for smoke channel. It consists of two main parts, a plate-shaped sealing surface 2 and a functional part 3.
the sealing surface 2 is made of elastic rubber and has, for example, a size of 47x47 cm.
the length of the functional part 3 can z. B. 35 cm and the width c. 11 cm.
the jacket of the functional part 3 consists of thermoformed plastic, such as HDPE or ABS. Underneath the jacket is a plastic discharge channel 4 having a starting end 5 and a closing end 6, and an axial fan 7 having a motor.
room 8 for power sources such as batteries or batteries formed. The power sources can be replaced by the gap 9.
the light-emitting diode 10 set up near the terminal end 6 of the discharge channel can be seen.
the light from the light emitting diode is aligned with the gas flow from the discharge channel 4.
an off switch 11 to recognize, with which the function of the light emitting diode 10 and the motor 7 is controlled.
the circuit breaker has three functions, the alternative being a) turning everything on, b) only switching on the light emitting diode, c) turning on the light emitting diode and the blower.
the function c) is used in the normal cleaning situation of the smoke channel.
function b) may be used on the way to the workstation or else when additional lighting is needed. It is possible to set up the arrangement also with an effective light source, which arrangement can be used as a flashlight.
Finger grooves 12 are formed in the jacket so that the handling of the arrangement with one hand would be as easy as possible.
a passage 13 is formed for the sweeping line.
the size of the passage 13 is only a little larger than the thickness of the sweeping line, the pressure loss during the operation is small.
the openings 13 and 5 are arranged in a straight line, so that during the operation, the sweeping line running through them can run out of or opening 5 untouched.
the edges of the opening 13 are rounded so that the line hardly wears in the operation.
grooves 14 are formed on the surface of the plate-shaped sealing surface, by bending along which the size of the sealing surface 2 is adjusted according to respective needs.
these grooves 14 could be arranged on the entire circumference of the plate 2 and in different directions, but because of the clarity of the figures, only these two grooves 14 are shown. It is also possible to produce the sealing surfaces 2 of such elastic material that no bending elements are needed.
the sweeping line may be in place or in the arrangement 1 in its place all the time.
the leash passes through the openings 5 and 13 so that the broom, ball and other accessories intended for the flue duct are in the assembly at the side of the opening 5 and the excess leash in the arrangement is at the side of the opening 13.
the leash may have a loop in a suitable place through which a split pin or the like. set and the arrangement and its accessories can be closed in a suitable funding or provision.
a splint In the transport position, such a splint is fitting against the opening 13 and seen from the line on the side 5 of the opening so that the arrangement can be carried on the shoulder.
the assembly 1 is usually placed against the back of the wearer and the ball against the chest.
the assembly 1 is easy to carry out about the same weight as the most common broom / ball combinations, the assembly remaining well on the shoulder.
a lightweight assembly 1 having a soft frictional sealing surface 2 is easy and safe to carry.
the assembly 1 When starting the cleaning of a common smoke channel, the assembly 1 is placed at the end of the smoke channel, so that the ball and broom connected touch the smoke channel to be cleaned.
the opening 5 at the beginning end of the discharge channel is placed at the location of the smoke channel.
the sealing surface 2 is folded to a suitable size and placed as close to the smoke channel.
the fan 7 is turned on. Any sap that holds the leash will be deducted.
the broom will fall down into the smoke channel.
the sweeping is performed, and at the same time, it is observed all the time that soot leaks from the opening 5 of the terminal end of the discharge channel. In dark weather, the light from the LED 10 helps to detect the escape of soot.
the line runs smoothly through the openings 5 and 13 and the arrangement 1 need not be lifted or moved during sweeping.
Effective sweeping requires rigid bristles from the broom. That is, the rest friction between the broom and the flue is so great that the broom does not usually fall by itself because of the weight. In practice, it is usually sufficient that the broom in the upper position is at least approximately completely removed from the smoke channel, the broom already gets a small start. Because of the lowliness and lightness of the arrangement according to the invention, it is easy to lift even in the narrow places with one hand a small distance required for this measure. In the vacuum blower 1 according to the invention for the smoke duct, the broom or at least the clamping bushes located above it and the like can be used. be lifted over the plane of the sealing surface 2 in the space 15 between the openings 5 and 13. In the FIG. 5 this space is 15 in the bend of the discharge channel 4. Already this space is often sufficient to afford the earlier mentioned start. Thus, the inventive arrangement 1 often does not need to be lifted or moved during sweeping.
the invention with its passages 13 and spaces 15 would also work with a different type of sealing surface than in the case of the sealing surface shown in the figures or even without special sealing surface.
