[0001] The object of the invention is the longitudinal profile particularly of the linear
radiant heater and the housing of the linear radiant heater emitting infrared radiation.
These elements are to be used in small, electrically driven, infrared radiant heaters.
[0002] In known electrically driven, linear radiant heaters emitting infrared radiation,
the heater housing consists of a one-piece, longitudinal body in the shape of a vault
while the side covers are mounted to the body sides. Moreover, the housing is usually
fitted with a holder for mounting the heater.
[0003] For instance, the utility model Ru 60147 is the radiant heater housing made out of
aluminum profile of a spatial construction, which constitutes a monolithic unit with
the reflector. The sides are secured with the covers in the form of screwed plates
with the outline adjusted to the housing shape. This type of housing is adapted to
the specific radiant heater size and its transverse parameters cannot be changed.
Moreover, it is difficult to make ventilation openings in it, which significantly
extends the time of the heater manufacturing.
[0004] The problematic issue in the case of infrared radiant heaters is the high temperature
which has a significant impact on the shape and size of the housing and the applied
cooling system of this housing. The necessity of dissipation of large heat volumes
which are generated in the area of the filament often leads to an increase in the
housing size and the space between the reflector and the housing. This, in turn causes
the increase in the labor and material costs.
[0005] The aim of the invention is to develop the longitudinal profile which will enable
the construction of modular housings of various sizes. This will cause a significant
reduction of the housing manufacturing costs and thus the reduction of costs of the
complete radiant heater. The aim of the invention is also to develop a minimized,
simple and inexpensive radiant heater housing.
[0006] The longitudinal profile particularly of the linear radiant heater is characterized
in that it has the shape of a strip on the edges of which there are slotted guides
positioned and on the inner side of the strip there is at least one slotted or pass-through
projection or a guide for determining the heater elements.
[0007] The profile is characterized in that in cross-section, the strip side is in the "C"
letter shape.
[0008] The profile is characterized in that in cross-section, the strip side has the shape
of a flat bar.
[0009] The profile is characterized in that it contains at least one external guide.
[0010] The housing of the linear radiant heater emitting infrared radiation containing a
vault-shaped longitudinal body, side covers, upper covers and if applicable a mounting
holder, according to the invention is characterized in that the longitudinal body
has the split construction composed of at least two profile longitudinal strips favorably
made out of the longitudinal profile according to the invention and which are favorably
positioned symmetrically to one another.
[0011] The housing is characterized in that the profile longitudinal strips are connected
to one another with connectors located along the body or on the body sides.
[0012] The housing is characterized in that the connector along the body has the form of
at least one bottom strip favorably perforated of the width chosen from the model
range.
[0013] The housing is characterized in that the connectors along the body have the form
of at least one upper cover of the width chosen from the model range.
[0014] The housing is characterized in that the connectors at the body sides have the form
of the side covers of the width chosen from the model range.
[0015] The housing is characterized in that the side connectors have the form of the longitudinal
elements of the length chosen from the model range and with the screw holes located
at the ends of these elements.
[0016] The solution according to the invention allows for a simple and quick assembly of
various size radiant heaters. By cutting the longitudinal profile to appropriate length
and selecting the connectors form the model range of a specific width and length,
it is possible to manufacture radiant heaters in line with any order, saving time,
materials and labor. Manufacturing simple connectors of various dimensions is significantly
cheaper than manufacturing the complete housing. The invention solves also the problem
of the radiant heater ventilation because depending on the needs, the ventilation
system may be direct, that is without mounting the bottom strip, or with an open-work,
bottom strip with a chosen model of ventilation openings. Additionally, the radiant
heater is characterized in an aesthetically pleasing and compact design.
[0017] The invention in its production option is shown in the figure where fig.1 and fig.
2 shows the longitudinal profile in cross-section with the side in the "C" letter
shape, with a various arrangement of projections on the interior side, fig. 3 shows
the longitudinal profile the side of which has the shape of a flat bar in cross-section
while on the outside there is a profiled external guide, fig. 4 shows the radiant
heater housing in a perspective view with the use of connectors in the form of the
side covers., fig. 5 shows the radiant heater housing in a perspective view with a
connector in the form of the longitudinal element, fig. 6 shows the housing in a perspective
view with the bottom strip and side covers, fig. 7 shows the body elements in a perspective
view made out of the profile the side of which has the shape of a flat bar in a perspective
view, fig. 8 shows the connector in the form of the longitudinal element while fig.
9 shows the housing applied to an exemplary radiant heater.
[0018] In the production option, the longitudinal profile particularly of the linear radiant
heater, in cross-section, has the side in the shape of the "C" letter while at the
ends of the profile there are longitudinal, slotted guides
1 directed perpendicularly towards the longitudinal axis of the heater while on the
interior side of the profile there are two longitudinal projections located
2 with the screw holes which can be positioned in any place as it is presented in fig.
1 and 2.
[0019] The other production option shows the longitudinal profile which, in cross - section
has the side in the shape of a flat bar and is fitted with the same elements as the
longitudinal profile shown in the first option and additionally it has external guides
3 for example to place a logo or for mounting a holder.
[0020] In other production options, the profile in the shape as in the first or subsequent
options may have additional internal guides or pass-through projections for example
for cable or the heater routing.
[0021] The housing of the linear radiant heater emitting infrared radiation consists of
the longitudinal split body
4 which is made out of two profile longitudinal strips
5 made out of the profile the side of which, in cross-section is in the "C" letter
shape. The profile strips
5 are connected to one another by the connectors in the form of side covers
6 tighten to the strips
5 with screws. In this case, the ventilation system constitutes a gap which appeared
between the strips
5. The width of the housing may be changed by applying side covers
6 of appropriate width. The radiant heater cover grille, the upper covers
10 and the holder elements not shown in the figure are inserted into the slotted guides
1 located at the ends of the profile longitudinal strips
5.
[0022] In other production option, an additional connector in the form of an open-work bottom
strip
7 fabricated from plate is inserted to the housing as in the first option. The bottom
strip
7 is inserted into the slotted guides
1 located at the ends of the profile longitudinal strips
5.

with the cross-section in the "C" letter shape. The profile strips were connected
with a connector in the form of the longitudinal element
8 fitted with screw holes
