BACKGROUND OF THE INVENTION
[0004] 1. Field of the Invention
[0005] The invention relates to the art of fireplace manufacturing,
and more particularly, to a fireplace.
[0006] 2. Description of Related Art
[0007] As living standard increases, fireplaces are more and more
popular. Fireplaces are able to not only be used to get warm, but
also decorate interior atmosphere more or less.
[0008] In a work process of a conventional fireplace, pieces of
wood are placed into a hearth and air is supplied into the hearth
via air supply vents defined in a bottom of the hearth. Since the
air supply vents are only arranged in the bottom, not all positions
in the hearth are ensured to get sufficient air for burning and
there are always dead spaces in the hearth. Especially, margins of
the hearth usually lack of enough air and wood therein may burns
slowly and incompletely.
[0009] Furthermore, the air supply vents in the bottom of such
fireplace is in communication with atmosphere, which means an air
supply rate is constant for this fireplace. A speed of combustion
is not able to be controlled for this fireplace. One a user stops
use the fireplace such as going to sleep or going out the wood in
the fireplace will keep on burning until extinguish itself. This
may cause waste. Since ignition of such fireplace is usually
cumbersome, users may not like to extinguish it directly every
time

supply channel being defined by the upper deflector and a door of
the fireplace, the first air supply channel being, in communication
with the upper air supply opening and has an outlet facing a bottom
of the hearth, a lower deflector being provided on the bottom of
the hearth, the lower deflector having a concave surface facing a
back wall of the hearth, and, a second air supply channel being
defined in the back wall of the hearth, the second air supply
channel being in communication with the lower air supply opening, a
plurality of air supply holes being defined in the back wall and
being in communication with the second air supply channel.
[0012] Preferably, the lower deflector has a concave surface.
[0013] Preferably, a first and second smoke deflectors are provided
and are staggerly disposed, by which a "Z" type smoke channel is
defined.
[0014] Preferably, the first and the second smoke deflectors are
parallel with respect to each other.
[0015] Preferably, an adjustable ventilation door is respectively
provided for the upper and the lower air supply opening.
[0016] Preferably, each the adjustable ventilation door has a
handle firmly formed thereon.
[0017] These and other objectives, features, and advantages of the
present invention will become apparent from the following detailed
description, the accompanying drawings, and the appended
claims.

[0018] FIG. 1 is a schematic front view of the preferred embodiment
of the invention.
[0019] FIG. 2 is a left side view thereof And,
[0020] FIG. 3 is a cross-sectional view along A-A in FIG. 1.
DETAILED DESCRIPTION OF THE INVENTION
[0021] With reference to FIGS. 1 to 3, FIG. 1 is a schematic view
of the preferred embodiment of the fireplace of the invention. FIG.
2 is a left side view thereof FIG. 3 is a cross-sectional new along
line A-A of FIG. 1.
[0022] The invention provides a fireplace having a hearth 11. The
hearth 11 is a place for burning of pieces of wood. An upper air
supply opening 12 is defined on a top of the hearth 11, and a lower
air supply opening 13 is defined on a bottom of the hearth 11. The
hearth 11 is disposed on a frame 1. Air is supplied into the hearth
11 through the upper and lower air supply openings 12, 13.
[0023] An upper deflector 4 is provided on a front side of the top
of the hearth 11. A first air supply channel 112 is defined by the
upper deflector 4 and a door 6 of the fireplace. The first air
supply channel 112 is in communication with the upper air supply
opening 12 and has an outlet facing a bottom of the hearth 11. Air
enters from the upper air supply opening 12 and flows into the
hearth 11 along the first air supply channel 112.
[0024] A second air supply channel 111 is defined in a back wall 8
of the hearth 11. The second air supply channel 111 is in
communication with the lower air supply opening 13 A plurality of
air supply holes 81 is defined in the back wall 8 of the hearth 11
and in communication with the second, air supply channel 111. Air
enters the lower air supply opening 13, flows along the second air
supply channel 111, and goes into the hearth 11 through the air
supply holes 81.
[0025] A lower deflector ,5 is provided on the bottom of the hearth
11. The lower deflector 5 has a concave surface facing the back
wall 8 of the hearth 11.
[0026] In the fireplace of the invention, in a process of burning
of the pieces of wood, air enters the hearth 11 via both the first
and the second air supply channel 112, 111 The air entering the
hearth 11 from the first air supply channel 112 flows downward to
the bottom of the hearth 11 and then flow to the back wall 8 under
the redirection of the lower deflector 5. The air entering the
hearth 11 from the second air supply channel 111 flows forward from
the back wall 8 of the hearth 11. In a process of air supply, two
flows respectively from the first and the second air supply
channels 111, 112 will form a circular air flow, which increases a
perturbation of air in the hearth 11. Turbulent flow will be full
of the whole hearth 11 and occurrence of dead spaces for air supply
is thus being avoided. An incomplete burning of the wood from the
air supply dead spaces is thus being resolved.
[0027] In the fireplace of the invention. both the upper and the
lower deflectors 4, 5 have a concave surface. The concave surface
is able to increase a swivel of the flows of air in the process of
redirection of the air. Circulating swivel air flows are more
liable to be produced and air is more liable to be supplied to
everywhere in the hearth 11. An effect of air supply is thus being
much improved.
[0028] In the fireplace of the invention, a staggerly disposing
first smoke deflector 9 and a second smoke deflector 10 are
provided. A "Z" type smoke channel is defined by the first and the
second smoke deflectors 9, 10. The smoke channel is in
communication with a chimney 2, through which smoke produced in the
working of the fireplace will be discharged. For a more preferably
resolution, the first and the second smoke deflectors 9, 10 are
parallel with, respect to each other.
[0029] In the fireplace of the invention, an adjustable ventilation
door is able to be provided respectively for the upper and the
lower air supply openings 12, 13. The ventilation doors may be any
type of door as long as they are able to adjust a width of an
aperture of the upper and the lower an supply openings 12, 13. With
reference to FIG. 3, in this embodiment, an upper ventilation door
3 having an upper handle 31 thereof is provided for the upper air
supply opening 12. The tipper handle 31 is firmly formed to the
ventilation door 3. A lower ventilation door 7 having a lower
handle 71 thereof is provided for the lower air supply opening 13.
The upper and the lower handles 31, 71 are disposed on the hearth
and being rotatable. The width of the apertures is able to be
adjusted by rotation of the handles 31. 71, and then blow rates of
the upper and the lower air supply openings 12, 13 are able to be
changed.
[0030] In the fireplace of the invention. one adjustable
ventilation door 3 or 7 is provided for either the upper or the
lower air supply opening 12 or 13. Through adjustment of the
ventilation door 3 or 7, a quantity of the air entering the hearth
11 is able to be changed. Thus, the burning of the wood in the
hearth 11 becomes controllable. When a use would like not to use
the fireplace, the ventilation doors 3, 7 are able to be diminished
to decrease air flow rate. The burning does not have to extinguish
and at the same time, an exhaustion of wood may be lowered.
[0031] From above description, it is seen that the objects of the
present invention have been fully and effectively accomplished.
Embodiment of the invention has been shown and described for the
purposes of illustrating the functional and structural principles
of the present invention and is subject to change without departure
from the invention's principles. Therefore, this invention includes
all modifications encompassed within the spirit and scope of the
following claims.
