HEAT-DISTRIBUTING AND COAL-CONTAINING APPARATUS
BACKGROUND OF INVENTION
1. FIELD OF INVENTION =
[0001] The present invention relates to a barbecue grill and, more
particularly, to a heat-distributing and coal-containing apparatus for use in
a
barbecue grill.
2. RELATED PRIOR ART
[0002] A barbecue grill is often used to heat and hence cook food.
A
barbecue grill is operated by burning coal or gas.
[0003] Briefly speaking, a barbecue grill based on combustion of coal
includes a bowl for receiving a coal tray and a grid. In operation, the coal
tray is located in a lower portion of the bowl and used to contain coal. The
grill is located above the coal tray after the coal is ignited. Food is cooked
on the grid.
[0004] A barbecue grill based on combustion of gas includes a bowl
for receiving a burner, a heating plate and a grid. The burner is located in a
lower portion of the bowl. The heating plate is located between the burner
and the grid. In operation, gas is combusted at the burner to heat the
heating plate. The heating plate heat food located on the grid.
[0005] However, the heating plate cannot be used in the barbecue grill
based on combustion of coal. The coal tray cannot be used in the barbecue
grill based on combustion of gas. However, this forces a manufacturer to
make two flat elements and inevitably increases the costs of the barbecue
grills.
[0006] The present invention is therefore intended to obviate or at
least alleviate the problems encountered in prior art.

SUMMARY OF INVENTION
[0007] It is the primary objective of the present invention to
provide a
heat-distributing and coal-containing apparatus for use as a heating plate in
a
barbecue grill based on burning of gas or a coal tray in a barbecue grill
based on combustion of coal.
[0008] To achieve the foregoing objective, the heat-distributing
and
coal-containing apparatus includes a bent top and two trays. The trays
extend from two opposite portions of the bent top. Each of the trays
includes slots extending parallel to one another.
[0009] In another aspect, the heat-distributing and coal-containing
apparatus further includes two canopies extending from two opposite ends
of the bent top beyond the trays.
[0010] In another aspect, the bent top includes a ridge and two
slant
portions each of which extends to a corresponding one of the trays from the
ridge.
[0011] In another aspect, the slant portions extend at an angle of
120 15 relative to each other.
[0012] In another aspect, each of the trays includes an internal
portion
extending from the corresponding slant portion, a lower portion extending
from the internal portion, and an external portion extending from the lower
portion, thereby providing a space.
[0013] In another aspect, the internal portion of each of the
trays
extends at an angle of 150 15 relative to the corresponding slant portion,
thereby providing a bent portion between the internal portion of each of the
trays and the corresponding slant portion.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
[0017] Referring to FIG. 1, a heat-distributing and coal-containing
apparatus
10 can be used as coal tray in accordance with the preferred embodiment of the
present invention. To this end, the heat-distributing and coal-containing
apparatus 10 includes a bent top 11 formed between a first tray 20 and a
second
tray 30.

[ 0018] The bent top 11 includes a ridge 12 formed between two slant
portions
13. One of the slat portions 13 extends to the first tray 20 from the ridge
12.
The remaining one of the slat portions 13 extends to the second tray 30 from
the
ridge 12. Two canopies 14 extend from two opposite ends of the bent top 11.
Each of the canopies 14 includes two lower edges 15.
3b
Date Recue/Date Received 2022-02-25
[0019] Referring to FIG. 2, the bent top 11 is an inverted V-
shaped
portion. There is an angle 18 of 120 115' between the slant portions 13.
[0020] The first tray 20 includes a lower portion 22, an internal
portion 24, an external portion 26 and a bent rim 28. The lower portion 22
is formed between the internal portion 24 and the external portion 26. The
internal portion 24 extends from the corresponding slant portion 13. There
is an angle 17 of 150* 15 between the internal portion 24 and the
corresponding slant portion 13, thereby forming a bent portion 16 between
the internal portion 24 and the corresponding slant portion 13. Together,
the lower portion 22, the internal portion 24 and the external portion 26
provide a space 25. The space 25 includes an opening 23 at an upper
portion. The width of the opening 23 is larger than the width of the lower
portion 22. The bent rim 28 extends from the external portion 26. The
bent rim 28 enhances the strength of the external portion 26.
[0021] Similarly, the second tray 30 includes a lower portion 32, an
internal portion 34, an external portion 36 and a bent rim 38. The lower
portion 32 is formed between the internal portion 34 and the external portion
36. The internal portion 34 extends from the corresponding slant
portion
13. There is an angle 17 of 150 15 between the internal portion 34 and
the corresponding slant portion 13, thereby forming a bent portion 16
between the internal portion 34 and the corresponding slant portion 13.
Together, the lower portion 32, the internal portion 34 and the external
portion 36 provide a space 35. The space 35 includes an opening 33 at an
upper portion. The width of the opening 33 is larger than the width of the
lower portion 322 The bent rim 38 extends from the external portion 36.
The bent rim 38 enhances the strength of the external portion 36.

[0022] Referring to FIGS. 1 and 3, the heat-distributing and
coal-containing apparatus 10 includes slots 21 in a lower portion of the first
tray 20 and slots 31 in a lower portion of the second tray 30. Each of the
slots 21 extends to the external portion 26 from the internal portion 24 via
the lower portion 22. Each of the slots 31 extends to the external portion
36 from the internal portion 34 via the lower portion 32.
[0023] Referring to FIG. 4, a barbecue grill 40 is equipped with a
burner 41. The barbecue grill 40 includes two upper shoulders 43 and two
lower shoulders 47 on an internal side.
3.0 [0024] Each of the canopies 14 is supported on a corresponding one
of
the lower shoulders 47, thereby keeping the heat-distributing and
coal-containing apparatus 10 above the burner 41. A grid 44 is supported
on the upper shoulders 43. Thus, the grid 44 is located above the
heat-distributing and coal-containing apparatus 10. Food 46 is supported
on the grid 44.
[0025] In cooking, the burner 41 is ignited to burn gas to produce
flames 42. The flames 42 enter the space 35 via the slots 31, thereby
heating the heat-distributing and coal-containing apparatus 10. Then, the
heat-distributing and coal-containing apparatus 10 heats and cooks the food
46.
[0026] As shown in phantom lines, a coal 45 is located on the lower
portion 32. The flames 42 ignite the coal 45. Then, the burner 41 is
turned off, leaving the burning coal 45 to heat and cook the food 46.
[0027] As discussed above, the heat-distributing and coal-
containing
apparatus 10 can be used as a coal tray because the second tray 30 receives
the coal 45. The heat-distributing and coal-containing apparatus 10 can be
5
CA 3070707 2020-02-03
used in the barbecue 40 or a barbecue grill based on combustion of coal
only.
[0028] The present invention has been described via the
illustration of
the preferred embodiment. Those skilled in the art can derive variations
from the preferred embodiment without departing from the scope of the
present invention. Therefore, the preferred embodiment shall not limit the
scope of the present invention defined in the claims.
