Description
BACKGROUND OF THE INVENTION
[0001] (a) Technical Field of the Invention
[0002] The present invention relates to a smokeless grilling oven
of a barbecue, and in particular, a grilling oven employing
infra-red to heat a grate and its surrounding space and the food
placed on the barbecuing net.
[0003] (b) Description of the Prior Art
[0004] Barbecuing is a method of cooking food which normally has a
smoked smell which is rather tempting. Conventionally, the grilling
oven of the barbecuing stove employs charcoal as the burning
material, and a grate mounted onto the opening of the oven. In the
course of barbecuing of food, the dripping of barbecuing sauces or
the liquid fat from meat will drop onto the burning charcoal which
will reduce the charcoal's temperature. The smoke formed during
barbecuing will pollute the environment and affect the respiratory
system of people exposed to such an environment.
[0005] However, charcoal produces the greatest heat and best
grilling efficiency. To avoid barbecue sauce form dripping onto the
burning charcoal, the charcoal is normally placed at one side of
the oven to be away from the center of the barbecuing rack, but the
heat generated by the burning charcoal will be gathered to move
upward. This will not effectively heat up the food. Additionally,
when charcoal is employed in barbecuing, the formation of smoke or
ash cannot be avoided and pollution to the environment remains a
problem.
[0006] Even though some people feel that barbecued meat with a
smoked smell has a better taste and the surface of the barbecued
meat is crispy, this is normally true only if the heat is
appropriately controlled, wherein the barbecued meat will have a
good smell. When using a conventional barbecue stove to barbecue
meat, if the smoke pollutes the meat it is not healthy to consume
it. Therefore, it is an object of the present invention to provide
a smokeless grilling oven.
SUMMARY OF THE INVENTION
[0007] Accordingly, it is an object of the present invention to
provide a smokeless grilling oven comprising a grate, a frame body,
a plurality of infra-red heaters which equals the number of sides
of the frame body, and a slanting securing rack for mounting the
heaters, wherein the grate is placed onto the frame body and the
bottom edge of the frame body suspends the slanting securing rack
and the infra-red heaters are mounted onto the slanting securing
rack so that the emitting end of the heater is slopingly facing the
bottom of the grate.
[0008] Yet another object of the present invention is to provide a
smokeless grilling oven, wherein infra-red radiation is used to
roast food instead of burning charcoal. In this instance, there is
no incomplete combustion or no burning ash flying around to
contaminate the environment. Thus, the entire roasting process can
be easily achieved.
[0009] The foregoing object and summary provide only a brief
introduction to the present invention. To fully appreciate these
and other objects of the present invention as well as the invention
itself, all of which will become apparent to those skilled in the
art, the following detailed description of the invention and the
claims should be read in conjunction with the accompanying
drawings. Throughout the specification and drawings identical
reference numerals refer to identical or similar parts.
[0010] Many other advantages and features of the present invention
will become manifest to those versed in the art upon making
reference to the detailed description and the accompanying sheets
of drawings in which a preferred structural embodiment
incorporating the principles of the present invention is shown by
way of illustrative example.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] FIG. 1 is a perspective view of the smokeless grilling oven
in accordance with the present invention.
[0012] FIG. 2 is a perspective exploded view of the smokeless
grilling oven in accordance with the present invention.
[0013] FIG. 3 is the front view of the barbecuing stove of the
present invention.
[0014] FIG. 4 is a top view of FIG. 3 in accordance with the
present invention.
[0015] FIG. 5 shows the slanting securing rack of the smokeless
grilling oven in accordance with another preferred embodiment of
the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] The following descriptions are of exemplary embodiments
only, and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0017] FIG. 1 is a perspective view of a smokeless grilling oven
and FIG. 2 is a perspective exploded view of the grilling oven in
accordance with the present invention. The smokeless grilling oven
10 comprises a grate 20, a frame body 30, a plurality of infra-red
radiation heaters 40, 41 and the number of the heaters 40, 41 being
equal to the number of sides of the frame body 30, and slanting
securing racks 50, 51 for securing the heaters 40, 41. The frame
body 30 is formed from conduits 31, 32, 33, 34 enclosing to form
the frame body 34, and at least a pair of the conduits 31, 32 have
a relative edge protruded inward to hold the holding plate 35, 36
of the grate 20 so that the grate 20 can be placed at the frame
body 30. The bottom of the side of the frame body 30 is soldered or
fastened with slanting securing racks 50, 51 and the infra-red
heaters 40, 41 are mounted on the securing racks 50, 51. The
securing racks 50, 51 adhered with the heat emitting ends 42, 43 of
the heaters 40, 41 are formed into through holes 52, 53 having area
similar to that of the heat-emitting ends 42, 43 so that the heat
emitting ends 42, 43 are slopingly facing the bottom of the grate
20. Thus, the infra-red radiation is used to grille the grate 20
and the surrounding of the grate 20 to heat food on the grate. The
oil of the food and the barbecuing sauce applied to the food stuff
on the grate will pass through it but will not drip onto the
heat-emitting ends 42, 43. Thus, the surrounding environment will
not be polluted in the course of barbecuing.
[0018] FIG. 3 is a front view of the oven and FIG. 4 is the top
view of the smokeless grilling oven in accordance with the present
invention. The grilling oven 10 is mounted onto a stove 60. Due to
the fact that no smoke is generated, it can be used in the
home.
[0019] As shown in FIG. 5, the slanting securing frame 50, 51
connecting one end of the frame body 30 is vertically extended to
form suspension rods 54, 55 so that the heat-emitting ends 42, 43
of the heater 40, 41 are slopingly extended to the center position
of the grate 20.
[0020] As described above, the present invention provides a
smokeless grilling oven, wherein infra-red radiation is employed to
grille the grate and the surrounding of the grate and to heat the
food on the grate. The oil from the food stuff and the barbecuing
sauce will not drip onto the heat-emitting end of the heaters.
[0021] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described
above.
[0022] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention.
