Description

[0001] The invention relates to a table fireplace for use as a domestic decoration comprising a base and a glass body, wherein a burner unit is received in the base and the glass body is placed on the base and encloses the burner unit. STATE OF THE ART

[0002] For example, DE 20 2005 006 238 U1 shows a tabletop fireplace for use as a decorative element or as a heater. The base houses a burner unit that can be inserted into an opening in a simple base plate. The base plate is surrounded by a stand, and decorative materials such as sand can only be placed on the base plate to a limited extent in order to comply with the requirements of DIN EN 16647. Furthermore, the base plate reaches a higher temperature when the tabletop fireplace is operated for an extended period, as the hot burner transfers heat to the base plate. Therefore, after prolonged use of the tabletop fireplace, contact with the base plate should be avoided.

[0003] German patent DE 10 2021 103 784 A1 discloses a tabletop fireplace for use as a home decoration and / or heater, comprising a base and a glass body, wherein a burner unit is housed in the base and the glass body is placed on the base and encloses the burner unit. The burner unit is enclosed in a burner receptacle, the burner receptacle being designed so that decorative material such as stones or the like can be placed on the receptacle. However, the base is designed in such a way that, even with this variant, prolonged use of the tabletop fireplace causes the base to heat up, so that after extended use the tabletop fireplace can only be moved by hand to a limited extent.

[0004] Tabletop fireplaces, according to current technological standards, typically lack a defined airflow system for supplying combustion air to the flame when the burner unit is in operation. This leads to turbulence within the glass body, often resulting in an unsteady flame and potentially soot buildup. REVELATION OF THE INVENTION

[0005] The object of the invention is to improve a table fireplace for use as a home decoration, comprising a base, a glass body and a burner unit in the base, wherein the base does not heat up as much as possible even after prolonged use and wherein a defined air flow for the operation of the burner unit is to be achieved.

[0006] This problem is solved starting from a table fireplace according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous embodiments of the invention are specified in the dependent claims.

[0007] The invention includes the technical teaching that the base has a receiving pot with an upper receiving plate and a circumferential wall extending below it, wherein a cavity is formed under the receiving pot in which at least predominantly the burner unit is received, and wherein a decoration space is formed which extends between the circumferential wall and the glass body and which is filled with a decorative material.

[0008] The inventive design of a table fireplace offers the advantage that, due to the smaller diameter of the receiving pot compared to the diameter of the glass body, a decorative space is created which can be filled with decorative material and simultaneously serves as a thermal insulator. This allows the receiving pot to reach higher temperatures during operation of the burner unit without these temperatures being transferred to components of the table fireplace, such as those used for transport. A further advantage is created by the cavity in the receiving pot, from which air can be guided past the burner unit in such a way that the flame generated by the burner unit is supplied with air from below, so that the resulting flame above the burner unit burns very steadily and evenly.The result is a tabletop fireplace that is cooled by an airflow through the hollow space, thus protecting the unit and burner from overheating. Another advantage is that, despite its solid appearance, the hollow design allows for a moderate overall weight for the tabletop fireplace.

[0009] The following terms indicating direction, such as "from above" and "from below," refer to the orientation of the table fireplace when it is used with its base on a table or other floor, the glass body extending upwards so that the flame is above the burner unit, the receiving pot being, in a sense, upside down, the receiving plate forming a base, which is, however, located on top, and the surrounding wall extending below the top receiving plate and enclosing the cavity on the underside of the receiving plate.

[0010] The table fireplace can have a diameter of 15cm to 40cm and a height of 20cm to 60cm, wherein a preferred first size has a diameter of 30cm with a height of 38cm and a preferred second, smaller size has a diameter of 20cm with a height of 27cm.

[0011] The table fireplace, and thus the glass bowl, can preferably be circular; however, the glass bowl can also be square or polygonal, so that the entire table fireplace, especially the glass body and the base, is preferably circular, although it can also be square or polygonal, for example. The orientation for normal use of the table fireplace is such that, with respect to gravity, the glass body is positioned above the base, allowing the table fireplace to be placed on a table, for example, via the base, with the glass body extending above the base.

[0012] The tabletop fireplace can also be called an ethanol fireplace or decorative fireplace, since ethanol is typically used as a liquid fuel to operate the burner unit. However, fuel pastes are also available, allowing the tabletop fireplace to be operated with other fuels as well. The term "tabletop fireplace" indicates that the overall dimensions are, for example, 200 mm to 400 mm, with a diameter of 305 mm and a height of 380 mm, to give another example. Such fireplaces can be placed on a table, especially a garden table or similar, to serve as decoration or, depending on the application or country-specific regulations, possibly also as a heater.

[0013] The mounting plate preferably has an opening, particularly centrally located, into which the burner unit is inserted and which extends downwards into the cavity. The opening has air vents surrounding the burner unit, through which air from the cavity can be directed to the flame of the burner unit, even when the burner unit is inserted in the opening. This allows the combustion air to flow directly around the outside of the burner unit, and the fuel can burn with the surrounding air. Air can continuously flow in from the cavity below through the air vents, thus reducing turbulence, particularly within the glass body. This results in a very steady and soot-free flame.

[0014] A further advantage of the base is its integrated base unit, which houses the receiving pot. This base unit comprises a base plate and a surrounding outer shell. The table fireplace can be placed on a surface using the base plate, and the outer shell can enclose the base plate at a perpendicular angle, so that the base unit is formed either as a single piece or in multiple parts, consisting of the base plate and the ring-shaped outer shell. For example, the base unit can also be pot-shaped, with the outer shell projecting upwards from the base plate like a collar. A support element, such as a flat piece of hard rubber, can be attached beneath the base plate.

[0015] To advantageously connect the base unit to the receiving pot, the receiving pot can have an outwardly extending collar section at the lower edge of its circumferential wall, with a diameter such that it projects against and seals against an inner surface of the base unit's casing. In particular, the collar section can be welded to the inner surface of the casing with its outer circumferential edge. Adhesive bonding or a press-fit connection is also possible. The outwardly extending collar section simultaneously forms the lower boundary of the decorative space, preventing decorative material, such as sand or stones, from falling into the area below the collar section and ensuring that it remains on the outside of the receiving pot, thus maintaining airflow underneath the receiving pot.

[0016] It is also possible to provide for a preferably vertical gap between the base plate and the collar section, so that the cavity extends below the collar section and is sealed off by the casing. If the substructure, in particular the casing, has air inlet openings, air can continuously enter the cavity through these openings and ultimately supply the flame of the burner unit with oxygen via the air inlets in the opening of the receiving plate. The air inlet openings, for example, with an arrangement of two diametrically opposed openings, can simultaneously serve as carrying handles, since they can be designed so that a user can use them as a handle by inserting their fingers into the openings.

[0017] It is also conceivable that the glass body extends into the base and is held by it. Preferably, the glass body can project into the casing with a lower section on the inside and rest with its lower edge on the collar section. The lower edge of the glass body can preferably be bonded to the collar section, thus preventing the glass body from coming out of the casing when the table fireplace is lifted, and preventing, for example, sand used as a decorative material from escaping from the decorative space.

[0018] With regard to the burner unit's enclosure and optimal airflow for the burner flame, a protective ring can be applied to the top of the mounting plate. This ring encloses the opening for the burner unit and the air vents surrounding it. Simultaneously, the protective ring forms an outer boundary for the decorative material, such as sand or stones. This prevents the flame from reaching the stones or sand, thus complying with DIN EN 16647. Furthermore, the protective ring enhances the chimney effect, thereby increasing the air supply from the cavity.

[0019] It is also conceivable that, according to a preferred embodiment, the stones arranged in the decoration space are made of larvikite or a comparable heat-resistant natural stone material known for use as sauna stone and characterized by high resistance to temperature changes and heat storage capacity.

[0020] The stones can be infused with a fragrance oil. For example, by sprinkling them with fragrance oil before each use, the stones will heat up to temperatures of approximately 40-60°C during operation of the fireplace. The applied essential oils will then gradually evaporate, creating a pleasant fragrance. Because the protective ring separates the flame area from the decorative space, direct contact between the oils and the flame is prevented, ensuring the safe application of fragrance oil to the stones without any risk of ignition. This evaporation process is similar to the principle of a sauna infusion.

[0021] The decorative chamber can be filled with sand to the point where the sand level reaches the protective ring, ensuring that the pot, its surrounding wall, and the base plate are completely covered with sand and remain invisible from the side or top. This creates the effect of the burner flame burning directly within the decorative material, as only the area within the protective ring remains visible once the sand, and any stones, are added, are in place. The sand can be viewed through the glass body from the outside, and if stones are placed on top of the sand, they can extend completely within the annular gap between the outer surface of the protective ring and the inner surface of the glass body.

[0022] The components of the base can be made predominantly of stainless steel, for example 1.4301. Furthermore, an extinguishing cover can be provided, which can be placed on top of the protective ring or directly on the top of the burner unit, thus extinguishing the flame of the burner unit. The extinguishing cover can also include a collar so that it remains securely in place on the protective ring.

[0023] To ignite the burner unit, it can either be removed using a handle or lit with a long matchstick holder with a clamping device. DIN EN 16647 stipulates that the hand must be at least 14 cm horizontally away from the burner opening during the ignition process, necessitating a long matchstick holder, as the glass body is not removable from the base.

[0024] Finally, the base and the glass body can be rotationally symmetrical. In particular, the burner unit can be centrally located in the base. It is equally conceivable that the mounting plate of the glass bowl has two, three, or four openings, each containing a burner unit, especially with a protective ring. Depending on the dimensions of the table fireplace, one or more burner units can be used. All burner units can be supplied with air from the cavity or cavities below the glass bowl, and all burner units can be encased in the decorative material, especially sand, so that the glass bowl is no longer visible from the outside. PREFERRED EXAMPLE OF THE INVENTION

[0025] Further measures improving the invention are described in more detail below, together with a description of a preferred embodiment of the invention, with reference to the figures. The figures show: Figure 1 is a perspective view of the table fireplace with the features of the invention; Figure 2 is a cross-sectional side view of the table fireplace with the features of the invention; Figure 3 is a detail view according to the larger circular section in Figure 2 and Figure 4, another detailed view according to the smaller circular section in Figure 2 .

[0026] The Figures 1 and 2 Figure 1 shows a perspective and a cross-sectional view of a table fireplace 1 with the features of the invention. The essential components of the table fireplace 1 are, firstly, a base 10, for example made of stainless steel, and a glass body 11 made of a transparent, fire-resistant glass, for example Pyrex or borosilicate glass.

[0027] The base 10 essentially consists of two components: the receiving pot 13 and the base unit 19. The receiving pot 13 is enclosed within the base unit 19, so that the base unit 19, with its bottom plate 19a and side casing 19b, forms a boundary for the base 10. The receiving pot 13, with its top receiving plate 13a and surrounding wall 13b, is located within the casing 19b of the base unit 19. The diameter of the surrounding wall 13b is smaller than the diameter of the casing 19b, creating a decorative space 15 within this surrounding gap. This space is filled, for example, with sand 25, and stones 26 are preferably placed on top of it.

[0028] Within the receiving pot 13, a cavity 14 is formed in which the burner unit 12 is housed. The views show, by way of example, an extinguishing cover 27 on the top of the opening 17. If the extinguishing cover 27 is removed, a flame can be ignited with the burner unit 12. According to one variant, the extinguishing cover 27 can also be inserted into the protective ring 24 so that it rests directly on the burner unit 12. The protective ring 24 also forms the inner seal of the decorative material 16, for example, the sand 25.

[0029] The surrounding wall 13b of the receiving pot 13 has an outwardly projecting collar section 21, which extends from the inside against the outer shell 19b and thus closes off the decorative space 15 at the bottom. This creates a kind of double bottom, and in the area between the base plate 19a and the collar section 21, the outer shell 19b contains, for example, two diametrically opposed air inlet openings 22, through which air can continuously flow into the cavity 14. The incoming air enters the protective ring 24 via air openings and can finally combust with the fuel of the burner unit 12 above the burner unit 12.

[0030] The lower edge 23 of the glass body 11 rests on the upper surface of the collar section 21 and may, for example, be bonded to it. This prevents the glass body 11 from unintentionally detaching from the base 10.

[0031] Figure 3The detail is shown according to the large circle in Figure 2 with the receiving pot 13 and with the base unit 19 in the area of ​​the collar section 21, which extends outwards along the underside of the surrounding wall 13b. The collar section 21 thus forms the lower end of the decoration space 15, the illustration showing the lower part of the glass body 11, which extends inwards into the outer shell 19b and is bonded to the collar section 21 in the area of ​​the lower edge 23, in particular by means of an adhesive bond 34. The outer edge of the collar section 21 is welded to the inner side 20 of the outer shell 19b by means of a weld 32.

[0032] A support element 28, such as a hard rubber mat or similar material, is glued to the underside of the base plate 19a of the floor unit 19. The support element 28 ensures a secure stand for the table fireplace 1 and protects temperature-sensitive surfaces on which the table fireplace 1 can be placed from the higher temperatures of the floor unit 19.

[0033] Figure 4 The detailed view is shown according to the smaller circle in Figure 2 in the area of ​​the opening 17 above the receiving plate 13. In this embodiment, the protective ring 24 is formed integrally with the receiving plate 13a, for example by forming a collar; however, it can also be welded to the receiving plate 13a. The extinguishing cover 27 rests on top of the protective ring 24 and is provided with a collar to prevent it from falling off.

[0034] An intermediate ring 29, equipped with air openings 18, is welded into the opening 17 to allow air to flow from the cavity 14 to over the area of ​​the burner unit 12, so that this air can combust with the fuel of the burner unit 12. The burner unit 12 is inserted into a burner receptacle 30, and the intermediate ring 29 is welded to the inside of the protective ring 24 at its outer edge by means of the weld 31. The burner receptacle 30 is also welded to the inner edge of the intermediate ring 29 by means of the weld 33. This allows the burner unit 12 to be removed upwards from the opening 17, for example, to refill it or to replace it with a new burner unit 12.

[0035] The invention is not limited in its implementation to the preferred embodiment described above. Rather, a number of variants are conceivable, which utilize the solution presented even in fundamentally different designs. All features and / or advantages arising from the claims, the description, or the drawings, including design details or spatial arrangements, can be essential to the invention, both individually and in various combinations.
