Abstract

Wind extractor for chimneys and the like, which is intended to be mounted on the upper end of the pipe corresponding to a wood chimney or in those spaces where hot air or even smoke is needed in case of fire, is characterized by the fact that it consists of a series of vertical vanes fixed between a superior discoidal body and a lower crown, counting below it with a coupling neck to the chimney tube, and on whose neck is fixed a support in vane for the fixation of an axis vertical which at its upper end is continuous on an axis of rotation located above the upper cover of the vanes, said axis being mounted on a bearing associated with a base fixed to the upper surface of the upper cover of the vanes, while a cover for the bearing itself is provided on the underside of said upper cover.

Description

Wind extractor for chimneys and the like.

Object of the invention

The present invention relates to an extractor wind, especially applicable to wood burning fireplaces, intended for its coupling at the top and free end of the outlet pipe of chimney fumes.

The object of the invention is to provide a Simple, efficient and low maintenance extractor, basing your operation in the force of the wind.

Although the wind extractor, considered as of high temperature, is intended for application in chimneys of firewood, its use is not ruled out in all those spaces where hot air is needed, as well as those necessary evacuate fumes in case of fire, basing its operation on a bearing set on top of vanes ventilation, and the vertical arrangement of these.

Background of the invention

Although numerous types of extractors are known of horizontal blades, in no case are extractors known for the hot gas extraction applicable in wood burning fireplaces, rooms of boilers, ovens, etc.

However, there are extractors that apply for the function mentioned above, that is to say a hot gas extraction, although with the drawback of that in the chimney in which it is applied there are plasters, also presenting the limitation of not supporting high temperatures

Extractors are also known electric, although their blades, which are sometimes arranged horizontally, they are not suitable for application in the outlet pipe of fireplaces, boiler rooms, ovens, etc., and carry out the extraction of hot air and even smoke.

It should also mean that the extractors electrical systems currently known, regardless of limitations and inconveniences referred to, offer noise levels Extremely high and low performance, to which we must add a high weight of the extractor assembly.

Description of the invention

The recommended extractor has been designed to solve the problem described above, so that It is a high temperature wind extractor that works completely with the wind current, which can be installed in wood burning fireplaces or other spaces where air is needed hot, as well as smoke in case of fire.

More specifically, the extractor of the invention it is constituted from a set of helical vanes in vertical arrangement, held between a discoid top cover and a lower crown, with the top cap provided, above she, of a bearing complemented with a base and a cap of protection, and under said top cover a cover of the own bearing, extending this in a vertical axis that is linked by its lower end to a blade support, fixed on the contour internal of a lower neck of the extractor through which performs the coupling on the free end of the tube of the chimney in which it is applied.

The double row bearing and the rotation shaft thereof is located in the corresponding bearing base, which it is fixed to the upper surface of the upper vane cover vertical, fixing that is done by screws or any other appropriate system, such as rivets or others, with the particularity that the vanes are fixed to the top cover and to the crown or lower cover by lugging lugs established at the ends of the blades themselves in holes established for this purpose in the commented top cap and crown lower.

The extractor thus constituted is made of steel stainless and aluminum vanes, so that under the vertical arrangement of its pallets guarantees optimum extraction, regardless of the space in which it is applied or need to extract hot air, being able to withstand up to 400ºC in normal working conditions

The bearing arrangement at the top results in a longer duration of the extractor assembly and greater interval between maintenance times, contrary to what occurs in conventional extractors, where the bearing is located at the bottom, so its duration is shorter.

Said extractor is put into operation at slightest wind breeze, with zero energy cost and levels Significantly low noise compared to fans conventional axial or electric, with a light weight when being made of aluminum pallets and other elements Main in stainless steel.

Description of the drawings

To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

Figure 1.- Shows a view according to a exploding perspective of the different parts and components that they participate in the wind extractor object of the invention.

Figure 2.- Shows an elevation view lateral, with sectioned part of the wind extractor of the invention.

Figure 3.- Shows a plan view upper of the wind extractor shown in the figure previous.

Figure 4.- Shows a plan view bottom of the same wind extractor.

Figure 5.- Shows a detail of a palette vertical with clamping ears provided at the ends for its connection to both the top cap and the bottom crown of the extractor.

Preferred Embodiment of the Invention

As you can see in the referred figures, the extractor of the invention is constituted from a plurality of vertical vanes (1), fixed to an upper cover (2) formed by a discoidal body, and a lower crown (3), so that both the cover (2) and the crown (3) are affected by holes for anchoring and fixing corresponding lugs (4) established both superiorly and inferiorly in their own paddles (1).

Lowerly includes a neck (5) through the which takes place the coupling of the extractor assembly on the free end of the chimney pipe in which apply, on whose neck (5) inside it is fixed a support (6) that is fixed by rivets to that lateral surface inside the neck (5), as shown in figure 2, support (6) that constitutes the fixing means of an axis (7), this fixing being carried out by means of a nut (8), while superiorly the axis of rotation (7) is extended in a section (9) protected with a cap or top cover (10), and mounted on a double row bearing (11) complemented with a base (12) which is fixed, by screws or any other appropriate system, to the upper surface of the cover (2), being covered lower bearing (11) by a cover (13), as a bottom cap, under the top cover (2).

The size of the extractor will be determined logically by the diameter of the neck (5), the support being (6) fixed to the inside of said neck (5) in the form of a blade, while the number of vanes (1) of the extractor will be variable of according to the diameter of the neck (5).

Finally say that the bearing (11) is of double row to ensure a better turn in any situation.

Claims (2)

1. Wind extractor for chimneys and similar, that being planned to be mounted on the upper end of the pipe corresponding to a wood burning fireplace or in those spaces where it is necessary to extract hot air or even smoke in case of fire, it is characterized by it constitutes from a series of vertical vanes fixed between an upper discoidal body and a lower crown, having under it a coupling neck to the chimney pipe, and on whose neck a blade support is fixed for the fixation of an axis vertical which at its upper end is continued on a rotation axis located above the upper cover of the vanes, said axis being mounted on a bearing associated with a base fixed to the upper surface of the upper cover of the vanes, while a cover for the bearing itself is provided on the underside of said upper cover. 2. Wind extractor for chimneys and the like according to claim 1, characterized in that the vertical vanes have at their ends the fixing axis on corresponding holes established for this purpose both in the lower crown and in the upper cover.
