Description

The present invention relates to a compact solid-fuel wall fireplace, namely wood, which is a closed flat firebox, which can be highly flat, specially designed for an apartment or a private house.

The closest objective of the invention is to create a wall fireplace with a closed firebox, into which wood is fed automatically, based on a certain margin, and the built-in ignition can be controlled from a distance.

A wood burning fireplace in your own home creates comfort that everyone appreciates. In addition to the kind of bonfire, it delivers warmth, friendly atmosphere and comfort. Some people don’t have that craving for sentimentality. But for everyone, the view of the fire is a pleasant and calming sight that invigorates the heat emanating from it. In addition, he materializes and creates near him a gathering place and communication between family members and guests.

Meanwhile, a classic fireplace requires for its installation an appropriate space that cannot always be provided for in your home or, without creating inconvenience, free up enough space, especially in an apartment or a small private house.

Based on this, in order to nevertheless organize an attractive spectacle of the fireplace hearth, various solutions were found for those who cannot install a fireplace.

For example, fireplace lights recorded on a video cassette, which can be viewed in the place where the TV is located, or artificial fireplaces occupying a small space in which the visual device imitates the hearth of a fireplace are proposed.

Such a simulating device may include artificial logs made of plastic with electric lighting that creates red light, a dynamic light system for emitting a flame, ribbons lit with red and orange light and oscillating under the influence of an air stream, simulating arcing and kinetics of a flame, and other elements.

Advances in technology allow us to offer even more advanced devices. However, such devices look fictitious, since they are based on an illusion and do not carry the charm or warmth of a real fireplace fire.

The closest analogue of this invention is a fireplace according to DE 9105375 U1, F24B 1/08, 20.061991, including a refractory body, a closing feed opening, a grate, a storage chamber, a combustion chamber, an air supply device for burning and removing flue gases.

However, there is a real need for a genuine fireplace, which can be installed in an apartment or a private house, which occupies only a small floor area, or even represents a wall fireplace, which does not occupy the floor area at all.

The advantage of such a fireplace, in addition to a small volume, should be an optimal, even panoramic picture of the hearth, so that you can fully perceive the appearance of the flame.

In addition, this fireplace must satisfy various safety requirements, be practical in use and guarantee optimal cleanliness.

Preferably, he should perform his functions quickly, conveniently, neatly and safely, so that any user can quickly and easily use the fire of the fireplace without the slightest trouble.

The purpose of the invention is to create a compact wall fireplace with a closed firebox using solid fuel, a fireplace that would have great ease of operation and could be installed in an apartment or private house.

The invention is also aimed at creating a wall fireplace with a simple and automatic execution of its main functions: ignition, fuel supply, cleaning, etc.

Thus, to provide the necessary practical advantages in operation, this fireplace has a prescribed reserve of solid fuel, namely wood, with automatic feeding into the furnace. This feed will also be carried out quickly, conveniently, neatly and safely.

Since the use of this fireplace is usually limited in time, the reserve may consist of one solid fuel tank, designed for an average duration of about two to three hours, which corresponds to one evening.

To solve this technical problem, the fireplace according to the invention includes a sight glass, a firebox with a grate, preferably a remote ignition device, a supply of wood for automatic feeding into the furnace, an ash pan, dual combustion air and a flue gas removal system, all of which are arranged so that the fireplace is compact, i.e. had the smallest possible size.

To this end, each of the constituent elements of the invention is designed to contribute to the overall result, creating the demand for the proposed product with its many advantages.

So, the sight glass has the largest possible dimensions, panoramic with respect to the firebox. It is located in close proximity to the firebox, which allows you to fully contemplate the sight created by the fire. Preferably, it only protrudes slightly from the wall in which the firebox can be arranged, and therefore takes up very little space in the room where it is located.

An ash pan located under the grate can be buried in the wall. Therefore, it is easily accessible for emptying.

To improve functioning and automaticity, the furnace support grid or the grate is set in motion by alternately moving using a special mechanism, but also by moving the front air supply valve with which it is connected.

The ignition device preferably contains at least one shielded electrical resistance, which allows you to remotely and safely ignite a wooden log located on the grate of the furnace.

Wood stock is created, for example, by a vertical compartment, the height of which slightly exceeds the average diameter of the log. It is located at the rear of the fireplace and is adjacent to the firebox, with which it is separated by a heat-insulating wall, preferably hollow, which also serves to supply secondary combustion air to the firebox.

This fuel supply is replenished with a stack of wooden logs or round logs, or pieces of wood, with an average diameter adapted to the size of the storage compartment. The advantage is that the inclined platform at the bottom of this supply allows the logs or logs to roll or slide to the level of the firebox so that when the first log is used up, a new one will take its place. Preferably, this supply will be available for reloading from the side or back of the fireplace by opening on the opposite side of the wall in which it is installed, or in another way.

In one embodiment of this automatic feed, the supply may comprise a drawer for loading logs or round logs. It is possible to provide in this drawer for loading the installation of a kit that serves to store already stacked logs, which allows for early loading of firewood, saving additional time.

Fresh air for combustion is supplied in two ways. The main channel for primary air goes from the bottom of the front of the front air supply valve. An additional channel delivers secondary air for combustion and afterburning. This secondary air channel begins in the lower part of the rear side of the furnace and passes over the furnace through the separation wall, then exits through the lower edge of this wall and, on the other hand, through the afterburning area located above. Thus, this secondary air is preheated, and this device also allows you to create a layer of air in the dividing wall that forms thermal insulation, which protects the spare firewood and the released heated gases from ignition.

To this end, the dividing wall is preferably made in the form of two parallel vertical plates, the distance between which determines the amount of thermal insulation. This wall of the secondary combustion air supply allows you to create an additional air stream, which together with the main air provides complete combustion and afterburning of logs or round logs on the grate of the furnace and volatile substances, often not burned.

The air outlet at the end of the separation wall can be completely free or through several openings, the rational arrangement of which ensures the optimal distribution of air that supports combustion.

Finally, a device for removing flue gases is located in the upper part of the fireplace, above the firebox. It is preferably made in the form of a chimney with a vertical outlet or with a horizontal angled outlet. Preferably, it is a discharge duct such as a chimney or a type called micro-duct.

A fireplace in accordance with the invention will be described in detail hereinafter with reference to various figures. Equivalent elements shown in these figures are denoted by the same positions.

In this description, the front side of the fireplace means the side containing the sight glass, and the back side means the side that is not visible, since it adjoins the wall or is inside it.

According to the drawings, it can be seen that, in general, the fireplace 1 is a casing in the form of a flat parallelepiped, even extra-flat, or a box 2 of small thickness, forming a closed firebox with an opening on its face closed by a sight glass and view 3.

This sight glass 3 is held in a closed position, closing the firebox from the front side, but is movable or removable due to, for example, tipping over for the purpose of accessing and cleaning the firebox. For this, it is preferably bordered by an opening frame, which, for example, is removed by moving forward, providing access to the furnace inside the casing 2.

This flat casing 2 comprises two adjacent chambers: a combustion chamber 4, which forms the firebox itself and is located in the front part, and a fuel storage chamber or compartment 5, located in the rear part and designed to fill with a reserve of solid fuel 6, for example, from natural wood in the form of logs or round log 7, or specially pressed.

Two chambers 4 and 5 are separated on the greater side of their height by a dividing wall 8 in the form of a partition. This dividing wall 8 acts as a mechanical disconnector, but also as thermal insulation, in order to avoid heat transfer to the fuel supply 6 and, therefore, to increase the temperature too much in the storage compartment 5. This dividing wall 8 can perform an additional function, as will be described below.

The separation wall 8 is preferably made in the form of two plates, respectively, of the front 9 and the rear 10, parallel and vertical, enclosing between themselves a flat and thin inner volume 11, which can remain free, or can be filled with insulating material.

In a preferred embodiment, the internal volume 11 is free and therefore is filled with air as a fixed layer of air 12, or, preferably, a downward flow of air. Such a device makes it possible to realize an additional supply of fresh combustion air coming from outside, heated in contact with the plates, especially the front plate 9 of the separation wall 8. This air is defined below as secondary.

The main combustion air comes from an opening in the lower part of the front face of the casing 2, as will be shown below.

Depending on the variant of interest, the dividing wall 8 terminates in the lower part of the furnace with its lower transverse edge 13, which is preferably located on the right side of the furnace and has either a direct view, or bent or inclined, or any other shape, thereby forming a genuine area of air injection in the back of the firebox.

You can also provide an intermediate area of the air outlet located in the upper part of the wall 8 for fresh heated air to enter the volume of the combustion chamber 4, where afterburning can take place.

This area may have a simple air outlet in the form of a gap or other geometric shape.

It is also possible to provide several outlets of fresh secondary combustion air at various levels.

Thus, the air penetrating into the partition wall 8 can supply the combustion chamber 4 with fresh combustion air above the consumed log. The latter comes from the outside and, preferably, is pushed, for example, mechanically under the action of aerodynamic forces at the level of the combustion chamber or furnace 4.

Passing through the dividing wall 8, the air is heated from the front plate 9 of the wall due to its contact with the flame and the radiation of the furnace, thereby taking away a significant amount of heat during its downward movement. The layer of fresh air 12 thus forms thermal insulation for the storage compartment 5, which is located behind the firebox and in which there is a supply of firewood 6, which avoids ignition of this supply due to the excessively high temperature that direct heat transfer from the furnace could cause.

The outlet of the secondary air supplying the combustion chamber 4 at the end of the separation wall 8 is at least at the level of its lower transverse edge 13. It can be completely free and open, as shown in various figures. However, it can also be made in such a way as to orient the flow of exhaust air, for example, using a ventilation pipe or, preferably, a strip with openings, the rational arrangement of which will allow for optimal distribution of combustion air.

Fresh air is supplied to the separation wall 8, starting from the lower inlet 14 of the secondary air, preferably regulated, then it enters the back wall 15 of the storage compartment 5 and then to the upper wall 16, after which it is lowered into the separation wall 8.

The air inlet 14 in one embodiment may be thermostatically controlled, i.e. adjustable depending on various parameters, for example, the temperature in the room or the temperature near the fireplace, which provides some adjustment of the rate of combustion.

In order to carry out afterburning, i.e. the combustion of particles and volatile gases that have not burned in the center of the furnace, an afterburning area 17 is provided, located slightly above the source. This may be a series of calibrated holes located on one line parallel to the lower edge of the separation wall 8. The heated fresh air leaving these holes will introduce the necessary oxygen at a temperature suitable for igniting and burning out these particles. This will contribute to additional heat output, which will improve the overall thermal efficiency. The environmental aspect will also improve in the sense of the emission of unburned particles and combustible gases into the atmosphere.

Primary combustion air comes from the lower part of the front face of the casing 2, where the adjustable primary air inlet 18 is located (Fig. 14). This primary air inlet 18 can be implemented as a series of openings 19 drilled on one horizontal line and covered by a more or less moving intermediate part 20 with the same sequence of openings 21 located in front of the first in order to control the air flow and, consequently, the combustion process. This intermediate part is installed with the possibility of linear movement, for example, when two rectilinear holes 22 and 23 interact with the locking screws 24 and 25, respectively. The intermediate part is moved by the lever 26. The block of this input 18 of the primary combustion air in the frontal arrangement is a front gate valve air 27. It is protected by a plate 28.

Here, the supply of the main combustion air can also be thermostatically controlled, i.e. its regulation, namely thrust, will depend on various parameters indicated above, with the aim of changing and regulating the combustion process.

The furnace itself is formed by a support or grate 29 mounted above a mechanical unit 30 containing an ash receiver or an ash pan 31. The grid is equipped with limiters 32 for keeping the logs at a certain distance from the glass surface.

To comply with the aesthetics and technical form, the ash pan 31 is preferably flat in the form of a drawer and easily accessible, for example, from one of the side faces.

The grate of the furnace 29 is the end part of the automatic solid fuel supply zone 33, which is preferably wood here, from the storage compartment 5. This supply zone 33 consists mainly of an inclined platform 34 forming the bottom of the storage compartment 5, in which the firewood is laid in the form of logs or round timber 7.

This inclined platform 34 allows each log 7 contained in the storage compartment 5 to advance by sliding or rolling by gravity, entering the combustion chamber 4 to the grate 29, successively replacing the spent log 7.

The logs or round logs 7 are in contact with each other, but it is possible to provide intermediate logs for the logs or round log 7 and / or the presence of a side valve for entering the furnace, or an equivalent means of full or partial access, without going beyond the scope of the invention.

Of course, you can use firewood in the form of logs or round timber 7, but other types of wood, for example, pressed, agglomerated or molded from waste wood or similar solid and combustible material, can also be used.

Additionally, for convenience, the movement of the grate 29, which has its own lever 35, is coordinated with the movements of the intermediate part 20 of the front gate valve 27 of the air inlet.

This coordination can be realized, as shown in Fig. 15, only by two transverse elements 36 and 37, for example, screws or other fasteners, the ends of which are included in the corresponding transverse groove of the grate 29. Thus, when the intermediate part 20 of the inlet gate moves air 27 emptying from ash is carried out automatically.

To further improve usability, the furnace is equipped with an autonomous ignition device, for example, with remote control.

As shown in FIG. 15, in particular, it can be a question of at least one shielded electrical resistance 38 in the form of a bracket, which is located in the upper part of the grate 29 and directly contacts the log 7 located on the grate. Remote control, for example, in the form of a switch I, located on the front side or near the fireplace, allows you to apply electrical power to the shielded ignition resistance by means of an adjustable timer. The ignition resistance 38 is heated, which allows you to directly set fire to the log 7, located on the grate 29 and easy to ignite the fire of the fireplace, without the need to open the door of the furnace or use matches. This eliminates the risk of accident and pollution.

It is important to note that possible contaminants emanating from the firewood storage compartment 5 also fall under the action of gravity along the inclined platform 34 for supplying firewood and end up in the ash pan 31. This allows you to keep the entire fireplace device clean.

The entire cavity is closed on the sides by two doors 39 and 40, completely closing the side faces. The doors are controlled to open with the handle 41 by turning around the front axle.

As can be seen in FIGS. 8 and 9, at least one side of the cavity has a side access hole 42 in the storage compartment 5 of solid fuel for loading it. Since this hole passes a certain amount of heat coming from the furnace, it was necessary to protect the space facing the door with a flanged and heat-insulated section 43, in order to avoid heat transfer to the door body. The same applies to section 44, facing the outlet of the ash pan 31, which is also flanged and thermally insulated.

The furnace 4 is closed in front with a removable sight glass 3 of a special material that allows you to observe the flame. Its inner surface is closed in the upper part by a heat-absorbing plate 45.

The part of the combustion chamber 4, located above the grate 29 and enclosed between the insulated partition wall 8 and the sight glass 3, forms the volume in which the flame develops. This part of the combustion chamber 4 continues upward with an intermediate container called a chimney box 46, or its equivalent in the form of an outlet 47 on a straight 48 or curved 49 chimney to remove smoke and combustion products.

According to a preferred embodiment, the container of the chimney box 46, which occupies the upper part of the combustion chamber 4, may also contain one or more deflecting plates 50 designed to direct smoke and combustion products to the inlet of the chimney 48 or 49 and inserted into the outlet 47, which serves as their connecting detail. This outlet 47 can also be positioned so as to form an outlet through the plate 51 and the coaxial channel 52 of the micro-duct type. The top of the fireplace is covered with a grill 53 for aesthetics. The output can also be vertical. In this case, the outlet 47 is directed upward and crosses the grill 53, connecting to a straight and vertical chimney 48 or a curved chimney 49. The latter may or may not be visible. If it is visible, it is provided with a closed casing 54, which serves as a shell at the same time. It opens at the top of the hatch 55, which allows to release into the upper part of the room a stream of warm air containing the generated heat emitted by the chimney 48.

The front of the casing 2 is closed over the entire height by the main pivot door 56, which provides protection, aesthetics and surveillance. This main door 56 pivots about a lateral axis, left or right. It contains locking means in the closed position.

The main door 56 is double. It consists of a main panel 57 made of opaque glass in one part of its surface, and has a central window opening for observation 58 of a rectangular shape facing the sight glass 3. As can be seen in FIGS. 2-5, the general shape of the main panel 57 is rectangular or oval. Of course, other aesthetic forms are possible.

The main panel 57 comprises, at some distance and on its rear side, a secondary panel 59 of transparent glass or other similar heat-resistant material. This panel is held, for example, by a frame and is superimposed when closing the door on the sight glass of the casing 2. The main door 56 can also be considered a double stained-glass window. This sequence of glasses in front of the flame provides not only direct observation of the flame, but also reflections and additional images, which increases the charm and magic of the flame.

The flat shape of the casing 2 and the fireplace 1 assembly makes them suitable for wall mounting, installation in the wall itself and placement on all kinds of supports without the need for significant technical work.

Due to these advantageous characteristics, the fireplace 1, flat or super flat, can be fully or partially inserted into the wall 60 or form only a slight protrusion, while its front surface coincides with the surface of the wall or is slightly extended from the wall, as shown in Figs.

However, the usual way of mounting the fireplace is to mount it to the wall 60 with the installation of an intermediate mounting plate 61 for insulation and aesthetics at a height of average human height, as shown in Figs. 12 and 13.

As already indicated, depending on the technical possibilities of placement, a direct exit through the wall is selected, for example, by means of a coaxial channel 52 such as a micro-duct, like wall gas heaters, or an exit through a vertical chimney 48 with a casing 54 and a hatch 55 for the release of warm air.

It is important to note that the fireplace 1 according to the invention can be adapted to any type of room or dwelling and is installed at various heights as desired, while classic fireplaces are installed on the floor. It can also be mounted on a pedestal or suspended at any height of a partition or wall.

The fireplace is quite easy to install as a wall, as it does not require any preparatory work. Its function is also very simple, because to light a fireplace fire, it is enough to load firewood and turn on the ignition device remotely. Its maintenance is very simple, as there is no need to clean the fireplace. It is only necessary to periodically empty the ash pan 31 and fill the storage compartment 5 with wood, since the main operation for unloading the ash is carried out by maneuvering the front gate valve 27 of the primary air inlet.

According to the manual version, the storage compartment 5 is replenished with firewood by adding logs one by one and stacking them on top of each other.

This characteristic can be further improved from the point of view of comfort, if you operate a retractable unit or kit 62, pre-filled or generally purchased for subsequent input directly or using the loader into the storage compartment 5.

According to another implementation method shown in FIG. 16, the supply of firewood 6 comprises a loading kit 62 and its support in the form of a loading sliding block 63, which, when filled, is introduced laterally into the storage compartment 5 by advancement using the locking bar 64 as a sliding platform.

It may also be envisaged to replace the empty loading drawer unit 63 with another, complete unit, pre-filled and possibly sold empty or complete in this form, like a standard loading unit, and empty units may even be reused.

As shown in FIG. 17, the storage compartment 5 forming the supply 6 may have a special loader 65 in the form of a box with a receiving compartment 66, with a side opening deviating outward to receive the loading kit 62, in which the logs or round timber 7 are stacked. so that the fireplace block as a whole is flat, the depth of the special loader 65 is limited and corresponds to the diameter of the firewood contained in it 7. Its overall height depends on the height of the fireplace, but in general should be such as to contain enough firewood for several hours of burning.

For fireplaces embedded in the wall, it is also possible to provide loading of firewood from the rear side, i.e. on the other side of the wall.

In general, the fuel supply 6, namely wood, can be renewed as necessary, even when the fireplace is on. To do this, the empty drawer unit must be replenished or replaced with a complete unit.

You can also provide numerous options for these methods of implementation, without going beyond the scope of the invention.

This refers only to a square or rectangular fireplace. However, it is possible to imagine and realize a different shape, for example, triangular or circular, accordingly adapting the various components of the fireplace.

In addition, the remote control device for the ignition device can also be a switch operated remotely by means of a television signal, or one or more switches located in different places of the room in which the fireplace is installed, or any other remote control device, for example, an infrared remote control radiation affecting the electrical resistance of the ignition.

Due to the presence of a thermally insulating partition wall 8, the heat coming from the furnace and transferred to the logs 7 of the stock 6 through this partition wall 8 is not sufficient to cause ignition of this stock. However, it contributes to their drying, which significantly increases the readiness of firewood for burning.
