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 according to the preamble of claim 1, as also known from DE-A-4 309 180.

In the prior art are heating devices, followed by radiators or towel radiators called, the two vertically oriented manifolds and a variety fluidically connected to these headers horizontally aligned Have heating tubes.

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

However, the mentioned radiators or bathroom radiators, among others Esthetic point of view seen the disadvantage that the terminal area and optionally the control area in these radiators is freely accessible to the view of the observer. The otherwise very advantageous appearance of such a radiator is through the connection fittings and optionally existing electrical heaters, such as an electric Resistance heating rod together with control, intake valves, etc., often at the bottom End region of said radiator are arranged, lasting clouded.

In addition, temperature sensors, temperature indicating instruments, etc. are unclad and unprotected often at the lower end of such a radiator described above arranged and can be easily damaged, for example when cleaning.

Furthermore, radiators are known which in the form of one or more heating plates in a row are arranged, with such radiators usually via fasteners be welded together by the radiator pressed together at a high pressure and the material by the flow of high electrical currents in the connecting areas is melted to enter into an intimate connection.

With a reasonable yield, however, such production methods are only for plate radiators with several heating plates justifiable, if these are relatively small dimensions have, so that manufacturing tolerances are still acceptable.

Radiators are currently often hidden in window recesses, etc., as radiators usually still outwardly unsightly.

In certain areas, for example in the bathroom, radiators are becoming increasingly common However, dimensions to aesthetically pleasing design means. Here they are also called Textile dryer, such as towel dryer, used, which accordingly with a or multiple throughput options are formed. However, such radiators have the disadvantage that aesthetically designed radiator a relatively small radiating surface for a sufficient heat output for a room of a given dimension. For this reason, appropriate radiators, such as bathroom radiators, have large external dimensions to ensure adequate heat output to provide, or they need through additional heating options, for example a floor heating, to be supported.

It is a preferred object of the present invention to provide a heating device with a To propose cladding or to propose a cladding for a heating device, which also eliminates the above-mentioned disadvantages of the prior art. Especially Let a heater with a panel or a panel for a heater Be proposed that the lower portion of a radiator or towel radiator both from the view of a viewer and from mechanical effects protects.

This object is achieved by a heating device with the in the characterizing part of claim 1, View of the cover with the in the characterizing part of claim 7 listed Characteristics solved.

Advantageous embodiments of the device or panel according to the invention go out the respective subclaims.

The invention may also be directed to the problem of proposing a radiator assembly, which provides the disadvantages of the prior art remedy and should in particular Provide a heater that is aesthetically pleasing and on Provides sufficient heating capacity for the smallest possible space.

By the device according to the invention it is possible, for example unsightly connection fittings, Valve equipment, electrical connections for heating rods, etc., to conceal and at the same time to protect, on the one hand a higher operational safety and on the other hand a much improved overall appearance for a corresponding radiator can be achieved can. In addition, the likelihood of getting sharp-edged profiles in the Connection area of a radiator to injure, greatly reduced. Accordingly, it is particularly expedient, the cladding on the connecting portion of the heater, in particular at the lower end portion of the radiator or the heating device provided.

Advantageously, the cladding on an upper cover surface, which in the direction of Broad side of the headers has the same extent, as the front surface. hereby Not only can insight from above be denied, but beyond that, moreover be prevented that, for example, dust, etc. penetrates and an optionally existing resistance heating element or its electrical connections sets what is currently in Bathrooms can cause significant hazards, as in these rooms often too readily combustible tissue components, such as cotton threads or the like, occurrence.

In addition, the cladding may be provided with side surfaces which are attached to the Narrow sides of the front surfaces are arranged, and preferably at an angle to the Front surface are angled, so that the side surfaces of the contour of the manifold or the collecting pipes in the depth of the heating adjoins or adapts. hereby is also a side view of the area to be shielded at the invention Heating device prevents.

The cover surface or the side surface or side surfaces may recesses, openings or the like, in particular to pass the headers. In this way it is possible, the area to be covered of the radiator so much to enclose and isolate from the environment that from all the usual viewpoints no gaps or clearances or the like are present. Because of this configuration a very compact impression is the aesthetic value of the radiator together with the disguise in this form as very particularly outstanding. In addition, there is a risk that people who are in the area of such stop the trained radiator or towel radiator, injure, considerably reduced, since all edged parts of a radiator are covered and spaces etc. which can form a source of danger, at the thus formed fairing largely 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 collection tubes with a tubular radiator or a flat radiator is joined together. It occur between the consecutively arranged in parallel radiators due to manufacturing tolerances angular deviations from 3 to 6 °, with the usual manufacturing methods not with a acceptable result.

While panel radiators are made by the deformation of metal sheets can be tubular heaters by welding or soldering together Pipes are made. Flat radiators or Planheizkörper be on roller conveyor lines transported from one production station to the next production station and the Welding machines used for joining preformed sheets place at least ten spot welds per square decimeter of the radiator surface not infrequently are leaking.

Already due to the fact that tubular heater not for transport through the roller conveyor lines are suitable for flat panel heaters use, it is almost excluded, the radiators of different types with the same manufacturing methods and manufacturing machines.

In addition, the welding machines that are used to make the welds of the flat radiator or panel radiators are used, not suitable for tubular radiators, Since it is hardly possible in the welding connection of tubes a closed 360 ° covering weld seam, which also satisfies aesthetic aspects.

Heating devices can be particularly advantageously arranged with two successively arranged Radiators realize if this between a substantially continuous panel exhibit. The panel can cover the entire rear radiator or cover selected sections of the rear radiator. Alternatively or in addition The panel can connect fittings, thermostatic valve, etc., and similar components dress, which provided approximately at the lower end of the heating device according to the invention and via which a connection to a central heating system can be made. The panel may have ornaments, recesses and projections to a to leave a visual harmonious impression and / or a specific heat radiation characteristic to offer. If subsequent or pending from a partial fairing The technical characteristics mentioned in this context are also relevant seen in conjunction with the disguise discussed herein above as extremely advantageous.

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

In particular, a soldering has proven that works with copper solder, as copper due to its high capillary pressure pulls into all joints and a ideal connection both in the direction of stability and tightness as well as in the direction of Practicality of the manufacturing process provides.

Due to the different manufacturing processes arise in flat radiators and Tubular radiators even greater manufacturing tolerances, which only by suitable joining techniques be overcome between the individual radiators of the radiator assembly.

On the other hand, results from the later connection separately manufactured radiator the present radiator arrangement according to the invention the advantage to be exhibited, that the radiator of the arrangement can be colored differently. While standing the technology radiators that are welded together, for example, only as an arrangement could be designed in one piece monochrome, according to the invention, each of the Radiator of the arrangement to be colored individually, the radiator later together need to be connected.

Here are advantageously required fasteners that a manufacturing tolerances have receiving construction.

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

In the simplest case, the connection region can be perpendicular to the axis of the first and / or Having second terminal region extending at least partially planar first planar surface. The second terminal region has a corresponding second planar surface, wherein between the planar surfaces may be arranged a sealing element, for example an O-ring.

In order to be able to absorb the manufacturing tolerances, has one of the two planar surfaces advantageously smaller dimensions or a smaller diameter than that other plane surface. This allows the two flat surfaces and thus the two terminal areas mounted deviating from a coaxial arrangement of the two terminal areas become.

In addition, the O-ring can accommodate more tolerances by different is pressed.

Advantageously, this degree of freedom can be used to accommodate manufacturing tolerances create that also the two flat surfaces and thus the terminal areas connecting connecting element other inner dimensions or a different inner diameter has as at least one of the planar surfaces. As a result, at least one of Terminal areas within the limits specified by the connecting element misalign, whereby additional tolerances can be absorbed.

Additional degrees of freedom can be achieved in that the diameter or the Dimensions of the flange portion of at least one of the two terminal portion, the Planar surfaces are assigned to change in the axial direction.

In order to hold the sealing element in a predetermined position and to prevent the sealing element from being excessively squeezed, may advantageously be in the planar surface are arranged a groove which receives the sealing element partially.

To the terminal areas close to the respective radiator of the radiator arrangement can connect to the respective outer diameters or outer sections the connection areas also be arranged sealing means, for example when inserting or screwing the terminal areas in the respectively assigned Radiator are pressed sealing. For example, O-rings can be advantageous Sealant can be considered.

Will the above-described connecting element in one of its embodiments used, the radiator in question are the radiator assembly according to the invention on the one hand at their front-end supervision and on the other hand at the front-end supervision facing side each provided with holes or openings into which the connecting elements or their terminal areas are used. Here are the mentioned fasteners claimed both fluidically and mechanically as connecting elements. Accordingly, the connecting element described also has a supply or Return. To ensure adequate 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 at the corner regions of the respective radiator of the invention Radiator assembly are mounted. But also two, three or more than four of those described Connecting elements or the connecting elements described below or different of the connecting elements described here can in corresponding Be used manner.

To reduce the risk that the often much higher temperatures in the vicinity of the Connection fittings of a radiator can cause the inventive Panel heats excessively, the panel according to the invention is advantageously from a non or only poorly heat-conductive material, preferably plastic.

Advantageously, the cladding extends over the extension of the heating device or the band heater and / or forms a receiving space for heating and / or Control devices, such as a thermostat-controlled resistance heating, a automatic mixing control heater that displays an electric heater or downgrades in their performance, as soon as sufficient over a central heating network hot heat transfer medium is supplied.

Advantageously, can be in the heater according to the invention or behind the Cover hide a control device, the at least one temperature measuring and at least one control device for controlling a heating power unchangeable Energy flow, in particular an electric current, with an electric heater, preferably an Elekuro heating element or an electric immersion heater, wherein at least one throttle device for controlling or inhibiting the flow of the heating medium can be arranged in the supply and / or return of the heater. It can the Circuit 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 Dependent on a preset target or target room temperature for the heater and depending on the temperature of the heating medium, wherein the Target or target room temperature preferably be felt at the inlet of the heater should and wherein the inlet and / or the return of the heating medium by means of the throttle device can be controlled to or from the central heating system when the inlet temperature falls below a predetermined temperature value.

This training makes it possible in transitional periods, a mixed Zentralheizungsund To ensure Heizpatronenbetrieb for a heater according to the invention.

By this embodiment, it is also possible, the heater of the invention partly or completely shut off from the central heating system. The too tempering heater according to the invention can then only by the heating in the device heating cartridge are heated and the danger of neighboring rooms over heating up connected pipes and remote radiators will be eliminated. unnecessary Energy losses are also avoided. Automatically, the correct mode be selected, providing additional security. This is Especially important if the cladding of an optionally flammable Plastic is made, which occurs when high temperatures occur, for example if a heating rod is not or is poorly controlled, warping or even catches fire.

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

The lining according to the invention may have recesses or recesses, in which operating elements, such as an input device or keyboard arranged is to some or all control parameters, limits or the like, in particular the Target temperature of the room, a time at which the heating operation is to be started, enter.

As already stated, it is advantageous for the aesthetic impression when the control device is arranged behind the lining according to the invention, since in this way a separate installation in a wall box or the like is unnecessary. Also the safety aspect is thereby advantageously satisfied.

In that regard, arranged under the panel according to the invention, a timer means it is possible, heating periods, times for the beginning or the end of a heating period, Ramps and the like more, pre-program.

In the panel can also be, for example, a battery and / or a power supply to a power grid, a battery or the like more, well in front of the eyes of an observer and hide the access of unauthorized persons, such as children. In addition, it is It is possible by the use of a battery or a rechargeable battery, to an immediate Disconnect power connection, which can eliminate aesthetically less advantageous cable.

In addition, can be in the panel LED warning lights or LCD displays or arrange the like, the information about the current state of the battery or the battery can give. Also, operating status displays are conceivable, such as "heating mode on" or "Fault". The monitoring circuit can in the event that a network connection in addition is intended to connect an existing battery for charging temporarily to the network.

In addition, it is possible, due to the invention formed according to disguise to provide a surge tank without the appearance of a corresponding radiator or bathroom radiator would thereby defaced. Such a surge tank is needed especially if the radiator during the electrical additional operation completely decoupled from the heating network or operated completely self-sufficient. The expansion tank then offers the expansion space necessary for the heating of the filling fluid. The security gain here is quite significant, since under some circumstances elevated pressure surge tank by the lining according to the invention In addition, it can be protected against mechanical intervention from the outside.

In order to better withstand increased mechanical loads, the inventive Cladding also still with reinforcing ribs of the same Be reinforced material from which the panel according to the invention itself substantially is made, for example plastic. On the other hand, however, even reinforcements be included in other materials in the renewal fairing.
