Abstract

Heat is transmitted from preferably horizontal tubes between two vertical collectors connected to the flow and return pipes of a central heating system. The front (12) of the cladding extends between sections (22) adjoining the sides (16) and may incorporate an opening (26) for a valve or thermostat head. The region between the collectors is substantially covered across their width, while the length is partially uncovered so that the flow and return pipes are not entirely exposed.

Description

The invention relates to a heating device with a panel according to the preamble of claim 1.

The prior art includes heating devices, hereinafter referred to as radiators or bathroom radiators known, the two vertically aligned manifolds and a variety of horizontally aligned fluidically connected to these manifolds Have heating tubes.

Such radiators are used for optical reasons, especially in bathrooms Bathroom radiators are used because such radiators are not only used for heating, but also aesthetically indubitable advantages that conventional radiators at least do not have to show equally.

However, the radiators or bathroom radiators mentioned have among others from aesthetic point of view ago seen the disadvantage that the connection area and possibly the control area of these radiators is freely accessible to the viewer's gaze. The otherwise very advantageous appearance of such a radiator is due to the connection fittings and electric heaters, if any, such as an electric one Resistance heating element with control, inlet valves etc., which are often at the bottom End region of said radiator are arranged, tarnished sustainably.

In addition, temperature sensors, temperature display instruments etc. are uncovered and unprotected not seldom at the lower end of such a radiator, as described above arranged and can easily be damaged, for example when cleaning.

Furthermore, radiators are known which are in the form of one or more heating plates one behind the other are arranged, such radiators usually via connecting elements are welded together by pressing the radiators together at high pressure and the material due to the flow of high electrical currents in the connection areas is melted to form an intimate connection.

With a reasonable yield, however, such manufacturing processes are only for tarpaulin radiators acceptable with several heating plates, if these are relatively small have, so that manufacturing tolerances are still acceptable.

Radiators are currently often hidden in window niches, etc., because radiators are usually still unsightly on the outside.

In certain areas, for example in the bathroom, radiators are becoming increasingly popular Dimensions, however, to aesthetically appealing design tools. Here they are also called Textile dryers, such as towel dryers, used accordingly with a or more throw-through possibilities are formed. However, such radiators the disadvantage that aesthetically designed radiators have a relatively small radiation area for a sufficient heat output for a room of a given dimension. For this reason, appropriate radiators, for example bathroom radiators, have large external dimensions to ensure adequate thermal output to provide, or they need additional heating options, for example underfloor heating.

It is a preferred object of the present invention to provide a heater with a Propose cladding or propose a cladding for a heater, which also eliminates the disadvantages of the prior art listed above. Especially are a heater with a panel or a panel for a heater be proposed, the lower area of a radiator or bathroom radiator both in front of a viewer's gaze and before mechanical influences protects.

This object is achieved by a heater with those listed in claim 1 Features resolved.

Advantageous embodiments of the device or cladding according to the invention are based the respective subclaims.

The invention can also be directed to the problem of proposing a radiator arrangement, which provides a remedy for the disadvantages of the prior art and in particular is intended provide a heater that is aesthetically pleasing and on provides sufficient heating power in the smallest possible space.

The device according to the invention makes it possible, for example, unsightly connection fittings, Valve devices, electrical connections for heating elements etc., to hide and to protect at the same time, which on the one hand increases operational safety and on the other a much improved overall look can be achieved for a corresponding radiator can. In addition, the likelihood of sticking to sharp-edged profiles in the Violating the connection area of a radiator, greatly reduced. It is accordingly particularly useful, the cladding on the connection section of the heating device, especially at the lower end portion of the heater or heater to provide.

Advantageously, the covering has an upper cover surface, which in the direction of Broad side of the manifolds has the same extent as the front surface. Hereby can not only be denied an insight from above, but also can Prevent, for example, dust, etc. from penetrating and possibly on one existing resistance heating element or its electrical connections puts what is currently in Bathrooms can lead to considerable sources of danger, as in these rooms often too easily flammable fabric components, for example cotton thread or the like, occurrence.

In addition, the cladding can be provided with side surfaces on the Narrow sides of the front surfaces are arranged, and which are preferably at an angle to the Front surface are angled so that the side surfaces conform to the contour of the header or the manifolds in the depth of the heater connects or adjusts. Hereby is also a side view of the area to be shielded on the inventive Prevents heater.

The cover surface or the side surface or side surfaces can have recesses, openings or have the like, in particular to pass through the header pipes. In this way it is possible to largely cover the area of the radiator to be covered to enclose and isolate from the environment that from all usual directions there are no gaps or spaces or the like. Because of this configuration The aesthetic value of the radiator creates a particularly compact impression to be judged together with the cladding in this form as particularly outstanding. In addition, there is a risk that people who are in the field of such stop the trained radiator or bathroom radiator, injure it, reduce it considerably, because all angular parts of a radiator are covered and gaps etc. which can form a source of danger, largely with the cladding formed in this way be avoided.

The advantages to be achieved according to the present invention can also be based on that a tubular heater with horizontal and / or vertical heating tubes and accordingly vertical or horizontal or horizontal collecting tubes with a tubular heating element or a flat radiator is combined. Thereby occur between the Radiators arranged in parallel one behind the other due to manufacturing tolerances from 3 to 6 °, which with conventional manufacturing methods not with one acceptable outcome.

While flat radiators are made by deforming metal sheets tubular radiators by welding or soldering together Tubes are manufactured. Flat radiators or plan radiators are on roller conveyor lines transported from one manufacturing station to the next manufacturing station and the Automatic welding machines used to connect the preformed sheets, place at least ten welding spots per square decimeter of the radiator surface are often leaky.

Already because of the fact that tubular heaters are not for transport through the roller transport lines suitable that are used for the flat radiators, it is almost excluded, the radiators of different types with the same manufacturing methods and manufacturing machines.

In addition, the automatic welding machines are used for the production of the weld seams of the flat radiators or panel radiators are used, not suitable for tubular radiators, since it is hardly possible to use a closed connection when welding tubes To produce a 360 ° covering weld seam that also satisfies aesthetic considerations.

Heating devices with two consecutively arranged can be particularly advantageous Realize radiators if there is an essentially continuous covering in between exhibit. The paneling can cover the entire radiator or rear Cover selected sections of the rear radiator. Alternatively or additionally can cover panel fittings, thermostatic valve, etc., and similar components Dress up provided at the lower end of the heating device according to the invention are, and via which a connection to a central heating system can be made. The cladding can have ornaments, recesses and projections around one leave a visually harmonious impression and / or a certain heat radiation characteristic to offer. If following or leading from a partial cladding is mentioned, so are the technical characteristics listed in this context to be seen as extremely advantageous in connection with the paneling discussed above.

It is therefore necessary to use a soldering process for tubular radiators.

A soldering process that works with copper solder has proven particularly useful, since copper due to its high capillary pressure pulls into all connection points and one ideal connection in the direction of stability and tightness as well as in the direction of Practicality of the manufacturing process.

Due to the different manufacturing processes, flat radiators and Tubular radiators have even greater manufacturing tolerances, which can only be achieved using suitable connection technologies are to be managed between the individual radiators of the radiator arrangement.

On the other hand, the later connection results in separately manufactured radiators the advantage of the present radiator arrangement according to the invention, that the radiators of the arrangement can be colored differently. While at the booth der Technik Radiators, which are welded together, for example, only as an arrangement could be designed in one piece in one color, each of the Radiators of the arrangement are colored individually, the radiators later together need to be connected.

Here, connecting elements are advantageously required which have manufacturing tolerances have receiving structure.

Such connecting elements for the heating device according to the invention have one first and a second connection area, each in one of the radiators Arrangement can be determined. The relevant connection areas can be screwed in, fixed via sleeves or otherwise fastened.

In the simplest case, the connection area can be perpendicular to the axis of the first and / or second at least partially flat first plane surface. The second connection area has a corresponding second flat surface, with between a sealing element, for example an O-ring, can be arranged on the flat surfaces.

In order to be able to compensate for the manufacturing tolerances, one of the two flat surfaces has advantageously smaller dimensions or a smaller diameter than that other plan area. This allows the two flat surfaces and thus the two connection areas mounted differently from a coaxial arrangement of the two connection areas become.

In addition, the O-ring can accommodate other tolerances by making them different is pressed.

This degree of freedom can advantageously be used to accommodate manufacturing tolerances create that the two flat surfaces and thus the connection areas connecting connecting element different inner dimensions or a different inner diameter has as at least one of the plane surfaces. This allows at least one of the Connection areas within the limits specified by the connecting element misalign, so that additional tolerances can be compensated.

Additional degrees of freedom can be achieved in that the diameter or Dimensions of the flange area of at least one of the two connection areas that the Flat surfaces are assigned, change in the axial direction.

To be able to hold the sealing element in a predetermined position and to prevent that the sealing element is squeezed too much, can advantageously in a groove can be arranged on the flat surface, which partially accommodates the sealing element.

Around the connection areas close to the respective radiator of the radiator arrangement to be able to connect to the respective outer diameters or outer sections the connection areas can also be arranged sealing devices, for example when inserting or screwing the connection areas into the respectively assigned Radiators are pressed tightly. For example, O-rings can be beneficial Sealants are considered.

Will the connector described above in one of its embodiments used, the radiators in question are the radiator arrangement according to the invention on the one hand at the front supervision and on the other hand at this front supervision facing side each with holes or openings into which the connecting elements or their connection areas are used. Here are the connecting elements mentioned stressed both fluidically and mechanically as connecting elements. Accordingly, the connecting element described also has a feed or Return. To ensure sufficient mechanical stability of the radiator arrangement according to the invention To be able to guarantee, it is preferable if four of the described Connecting elements on the corner areas of the respective radiators of the invention Radiator assembly can be mounted. But also two, three or more than four of the described Connecting elements or the connecting elements described below or different connecting elements described here can be used in a corresponding manner Way are used.

To reduce the risk that the often much higher temperatures near the Connection fittings of a radiator can cause that the invention Heating the panel excessively, the panel according to the invention is advantageously made of a non-conductive or poorly conductive material, preferably plastic.

The cladding advantageously extends over the extent of the heating device or the band heater and / or forms a receiving space for heating and / or Control devices, for example a thermostatically controlled resistance heating element, a automatic mixing control heater that emits an electric heater or downgraded in performance as soon as sufficient via a central heating network hot heat transfer medium is supplied.

In the heating device according to the invention or behind the Hide a control device, the at least one temperature measuring device and at least one control device for controlling a heat output that cannot be converted Energy flow, in particular an electric current, with an electric heater, preferably an electric heating element or an electric heating cartridge, wherein at least one throttle device for controlling or preventing the flow of the heating medium can be arranged in the inflow and / or outflow of the heating device. The Switching the opening, throttling or interruption of the inlet and / or return of the Heating medium from or to a central heating system by means of the throttle device in Dependence on a preset target or target room temperature for the heating device and depending on the temperature of the heating medium, the Target or target room temperature should preferably be felt on the inlet of the heating device should and where the inlet and / or the return of the heating medium by means of the throttle device can be controllable to or from the central heating system if the inlet temperature falls below a predetermined temperature value.

This training makes it possible to have a mixed one in transition periods Central heating and To ensure cartridge heating operation for a heating device according to the invention.

This configuration also makes it possible to use the heating device according to the invention partially or completely shut off from the central heating system. The too The heating device according to the invention can then be heated by the heating device alone located heating cartridge are heated and the risk of neighboring rooms Heating up the connected lines and remote radiators is eliminated. Unnecessary Energy losses are also avoided. The correct operating mode can be set automatically can be selected, providing additional security. This is Of particular importance if the cladding is made of a possibly combustible Plastic is made, which occurs when temperatures are too high, for example if a heating element is not or poorly regulated, warps or even catches fire.

A room temperature sensing device can be used in the heating device according to the invention also be arranged to provide the control device with information about the actual To supply room temperature.

The cladding according to the invention can have cutouts or recesses, in which controls, for example an input device or keyboard arranged is to some or all control parameters, limit values or the like, in particular the Target temperature of the room, a time at which heating operation is to be started, to enter.

As already stated, it is advantageous for the aesthetic impression if the control device is arranged behind the panel according to the invention, because in this way a separate installation in a wall box or the like is unnecessary. Also the security aspect is thereby advantageously met.

In this respect, a timer device is also arranged under the cladding according to the invention heating periods, times for the beginning or end of a heating period, Ramps and the like, to pre-program.

A battery and / or a mains connection, for example, can also be in the casing to a power supply, a battery or the like, well in front of a viewer's eyes and hide access from unauthorized persons, such as children. Beyond that it is possible by using a battery or a rechargeable battery, to a direct one To do without the power connection, which means that less aesthetically advantageous cables can be omitted.

In addition, LED warning lights or LCD displays or Arrange the like, the information about the current state of the battery or accumulator can give. Operating status displays are also conceivable, such as "heating operation on" or "Disorder". The monitoring circuit can in the event that a network connection in addition it is intended to temporarily connect an existing battery to the mains for charging.

In addition, it is possible due to the cladding designed according to the invention to provide a surge tank without the appearance of a corresponding radiator or bathroom radiator would be defaced thereby. Such a surge tank is especially needed when the radiator is in use during additional electrical operation is completely disconnected from the heating network or even operated completely independently. The expansion tank then offers the expansion space necessary for heating the filling fluid. The gain in security is quite substantial here, since it may be under one increased pressure standing pressure expansion tank through the panel according to the invention can also be protected against mechanical interference from outside.

In order to be able to better withstand increased mechanical loads, the invention can Cladding also with reinforcing ribs from the same Be reinforced material from which the panel according to the invention itself essentially is produced, for example plastic. On the other hand, reinforcements can also be made be made of other materials in the new cladding.

It may also be advantageous to use ventilation slots or the like in the invention Arrange cladding, for example in the cover.
