Description
TECHNICAL FIELD
[0001] The present disclosure relates generally to ventilation
hoods. More particularly, the present disclosure relates to a
built-in kitchen retractable hood for ventilating the area around a
built-in cooking device such as a wall oven.
DISCUSSION OF RELATED ART
[0002] Cooking may create undesirable products such as combustion
gases, smells of food, heat, steam, grease, and so forth. These
products may pollute the air in a kitchen and even be harmful and
hazardous for people. It is traditionally desirable to safely
remove these products from the cooking area to outside.
[0003] Various kitchen ventilation hoods are developed to draw the
gas products away from the kitchen. The ventilation hoods are
conventionally disposed above the cooking area, because gas
products generally possess high temperatures, which cause them to
flow upwards. Typical kitchen ventilation hoods comprise a fan
configured to exhaust gas products to an outdoor space and a metal
casing made in a form suitable for collecting gas products from the
wide cooking area.
[0004] Most ventilation hoods are designed to be installed above
stovetops; however a typical kitchen may comprise many other
cooking devices that can produce undesirable gas products. Among
such cooking devices are wall ovens, microwave ovens, and so forth,
which are typically built into the kitchen cabinetry. There is no
known suitable and effective ventilation hood for removing gas
products generated by such built-in cooking devices.

example embodiments. These example embodiments, which are also
referred to herein as "examples," are described in enough detail to
enable those skilled in the art to practice the present subject
matter. The embodiments can be combined, other embodiments can be
utilized, or structural, logical and electrical changes can be made
without departing from the scope of what is claimed. The following
detailed description is, therefore, not to be taken in a limiting
sense, and the scope is defined by the appended claims and their
equivalents.
[0024] According to various embodiments disclosed herein, a
built-in ventilation hood assembly for air exhausting is provided.
The built-in ventilation hood assembly can be embedded in a kitchen
cabinet above a built-in cooking device such as a wall oven.
Accordingly, the built-in ventilation hood assembly is designed to
remove undesired gas products generated by the cooking device.
[0025] The built-in ventilation hood assembly may comprise a
housing, a ventilation unit installed therein, and a retractable
hood unit which can be slidably mounted within the housing. The
retractable hood unit may be driven by a user with the help of a
driving unit (e.g., an electric motor) that can cause the hood to
move from the retracted position to an extended position, and vice
versa. In some embodiments, the retractable hood unit can be moved
out from the housing on predetermined lengths (e.g., on a half
length and a full length).
[0026] The retractable hood unit may comprise an air intake (e.g.,
a plurality of openings or a lattice arranged on its bottom wall)
for exhausting air from the cooking area to an outside area.
Accordingly, when the retractable hood unit is extended from the
housing, the air can be exhausted through the air intake and be
forced through the ventilation unit to an external air conduit or
to an air filter and then back to the cooking area.
[0027] The built-in ventilation hood assembly may also be provided
with a transmission unit configured to transmit the force generated
by the driving unit to the retractable hood unit. In one example,
the transmission unit may comprise a gear coupled to the driving
unit and a rack coupled with the retractable hood unit.
Accordingly, the force of the driving unit can be transmitted via
the transmission unit to the retractable hood unit for sliding in
or out of the housing.
[0028] The built-in ventilation hood assembly may also comprise
multiple illumination devices to light the cooking area and light
certain parts of the assembly (e.g., corners, side walls, etc.). It
was shown that warning lights at the angles or boundaries of the
assembly help people be more careful and the number of injures can
be significantly reduced.
[0029] Referring now to the drawings, FIG. 1 is a diagrammatic
perspective view of a kitchen cabinetry 100 having a built-in

be exhausted by the built-in ventilation hood assembly 110 and
forced to the outside area through a set of conduits. In some
examples, the built-in ventilation hood assembly 110 may comprise
an air filter and an outlet (not shown) to force treated air back
to the cooking area.
[0033] According to some embodiments, the built-in ventilation hood
assembly 110 can be extended from the moved-in position to a
certain length depending on current needs.
[0034] FIG. 3 is a perspective view of the built-in ventilation
hood assembly 110, according to an example embodiment. As shown,
the built-in ventilation hood assembly 110 may comprise a housing
310, a retractable hood unit 320, and an air outlet 330 designed
for coupling with an external air conduit. As shown, the
retractable hood unit 320 is retracted within the housing 310.
[0035] The built-in ventilation hood assembly 110 may further
comprise a control panel 340. The control panel 340 can be arranged
on the front panel of the retractable hood unit 320 or on any other
wall of the built-in ventilation hood assembly 110. The control

out (extended) position, according to an example embodiment.
[0037] As mentioned, the retractable hood unit 320 may be slidably
positioned within the housing 310. In order to provide the ability
of moving the retractable hood unit 310, the housing 310 may
comprise one or more guiding members 410 (shown in dashed lines) to
receive the retractable hood unit 320. The guiding members 410 may
comprise, among other things, rails, racks, guides, ramps, ribs,
and shafts.
[0038] FIG. 5 is a diagrammatic top view of longitudinal section of
the built-in ventilation hood assembly 110 having the retractable
hood unit 320 in the slide out position, according to an example
embodiment.
[0039] The built-in ventilation hood assembly 110 may comprise the
housing 310 and the retractable hood unit 320 both having
rectangular parallelepiped forms such that the retractable hood
unit 320 may slide in or out of the housing 310. The sliding is
performed with the help of the guiding members 410 disposed within
the housing 310. In the shown example, the guiding members 410 are

In one example, the driving unit 510 comprises one or more electric
motors disposed within the housing 310. In the shown example, there
is a single electric motor 510 only, although those skilled in the
art would appreciate that any number of electric motors can be used
and disposed in different positions within the housing 310.
[0041] The driving unit 510 may further comprise a transmission
unit configured to transmit the force generated by the driving unit
510 to the retractable hood unit 320. The transmission unit can be
designed in many suitable variants and comprise one or more of
gears, shafts, racks, drive bands, chains, and so forth. In the
shown example, the transmission unit is made in the form of a gear
(not shown) coupled to the electric motor axis and a rack 520
movably attached to the gear at one end and stationary coupled to
the retractable hood unit 320 at the other end. When the electric
motor 510 rotates its axis, the driving force is transmitted
through the gear to the rack 520 such that it can move in back or
forward directions, and displace the retractable hood unit 320 from
the retracted position to the extended (slide out) position, or
vice versa.
[0042] The built-in ventilation hood assembly 110 may further
comprise a ventilation unit 530 which can be installed within the

[0043] The built-in ventilation hood assembly 110 may comprise one
or more air intakes. More specifically, the retractable hood unit
320 may comprise an air intake 540 arranged in its bottom wall. The
air intake 540 may be implemented as a hole or a set of openings
(for example, as a lattice). In some other embodiments, the
retractable hood unit 320 may comprise additional air intakes (not
shown). For example, the retractable hood unit 320 may comprise two
air intakes 540, which are arranged in such a way that when the
retractable hood unit 320 is extended to its half-length, it is
uses a first air intake only, but when the retractable hood unit
320 is extended to its full length, both air intakes can be in use.
In the latter case, the intake area can be extended when necessary
to exhaust air in a more intensive manner.
[0044] FIG. 6 is a diagrammatic side view of a longitudinal section
of the built-in ventilation hood assembly 110 having the
retractable hood unit 320 in the slide in (retracted) position,
according to an example embodiment. FIG. 6 further illustrates that
the built-in ventilation hood assembly 110 may be provided with one
or more illumination devices 610. The illumination devices 610 can
be configured to light the cooking area (e.g., the wall oven 120)
and may comprise one or more of electroluminescent devices such as
luminous tube lamps, filament lamps, LEDs, energy-saving lamps, and
so forth.
[0045] FIG. 7 is a diagrammatic side view of a longitudinal section
of the built-in ventilation hood assembly 110 having the
retractable hood unit 320 in the slide out position, according to
an example embodiment. FIG. 7 shows how the exhausted air can be
forced within the built-in ventilation hood assembly 110. When the
retractable hood unit 320 is in the slide out position, the air
flow may be sucked through the air intake 540 to the internal
compartment of the retractable hood unit 320 and then to an
internal compartment of the housing 310. The air flow is then
driven to the ventilation unit 530 and then forced outside via the
air outlet 330.
[0046] FIG. 8 shows a diagrammatic side view of longitudinal
section of the built-in ventilation hood assembly 110 having the
retractable hood unit 320 in the slide out position, according to
another example embodiment.
[0047] In this embodiment, the built-in ventilation hood assembly
110 is similar to the previously described embodiments; however, in
the shown example, the built-in ventilation hood assembly 110 may
further comprise a filtering unit 810 configured to treat the drawn
air. The filtering unit 810 may be implemented as a carbon filter
and can be integrated with a duct or the ventilation unit 530. The
filtering unit 810 may either be arranged in front the fan (of the
ventilation unit 530) or behind.
[0048] The built-in ventilation hood assembly 110 may further
comprise a duct 820 to transmit the treated air to an air outlet
830 such that the treated air can be returned to the cooking area.
According to various embodiments, the built-in ventilation hood
assembly 110 may comprise both air outlets 330 and 830 and,
additionally, a switch (not shown) to redirect air flow to any one
of these outlets. Such a switch can be arranged as an air guide
member (for example, a moveable baffle (not shown)).
[0049] FIG. 9 shows a perspective view of the built-in ventilation
hood assembly 110, according to an example embodiment. As shown,
the built-in ventilation hood assembly 110 may comprise the housing
310, the retractable hood unit 320, the air outlet 330, and the
control panel 340. In this embodiment, the built-in ventilation
hood assembly 110 may further comprise warning lights 910. The
warning lights 910 can be arranged on the front panel of the
retractable hood unit 320 and/or at the housing 310.
[0050] The warning lights 910 can be configured to warn users and
highlight the angles or any boundaries of the built-in ventilation
hood assembly 110. In the shown example, the warning lights 910 are
disposed on the opposite lateral sides of the retractable hood unit
320. The warning lights 910 may comprise one or more of
electroluminescent devices such as luminous tube lamps, filament
lamps, LEDs, energy-saving lamps, and the like. The warning lights
910 may draw the users' attention in order to prevent the users
from being injured by accidently hitting their heads or any other
body parts on the built-in ventilation hood assembly 110 when its
retractable hood unit 320 is in the extended position.
[0051] In one example embodiment, the warning lights 910 are
powered at the times when the ventilation unit 530 is activated. In
some other embodiments, the built-in ventilation hood assembly 110
may comprise a control to turn the warning lights 910 on or
off.
[0052] FIG. 10 shows a block diagram of electronic appliances of
the built-in ventilation hood assembly 110 and their
interconnection, according to an example embodiment. The electronic
appliances comprise the control panel 340, the driving unit 510,
the ventilation unit 530 (e.g., the fan), the illumination device
610, and the warning lights 910.
[0053] The control panel 340 may comprise one or more operation
controls such as buttons. In the shown example, the control panel
340 comprises a `Slide In/Out` button 1110 to control the driving
unit 510, a `Fan On/Off` button 1120 to control the ventilation
unit 530 (and, optionally, the warning lights 910), and a `Lights
On/Off` button 1130 to control the illumination device 610.
[0054] When a user presses the `Slide In/Out` button 1110, the
driving unit 510 is energized to slide out the retractable hood
unit 320 from the housing 310 or slide it in.
[0055] Furthermore, when the user presses the `Fan On/Off` button
1120, the ventilation unit 530 is powered to start blowing. When
the user presses this button again, the ventilation unit 530 is
caused to stop operation. In various embodiments, the control panel
may be provided with multiple buttons to control the ventilation
unit 530 and, in particular, to control fan speed. In some other
embodiments, each press on the button 1120 may cause a step like
change in the fan rotation speed. Those skilled in the art would
appreciate that multiple different button implementations are
possible depending on application.
[0056] In addition, in one example embodiment, the warning lights
910 can be automatically turned on when the ventilation unit 530 is
activated, and similarly, when the ventilation unit 530
deactivated, the warning lights 910 can be automatically turned
off.
[0057] When the `Lights On/Off` button 1130 is pressed by the user,
the illumination device 610 is either powered on or powered off. In
an embodiment, the illumination device 610 can also be operatively
coupled to the warning lights 910 such that the warning lights 910
are powered when the illumination device 610 is powered.
[0058] FIG. 11 shows a block diagram of electronic appliances of
the built-in ventilation hood assembly 110 and their
interconnection, according to another example embodiment. In this
embodiment, the electronic appliances comprise the control panel
340, the driving unit 510, the ventilation unit 530, and the
warning lights 910.
[0059] The control panel 340 may comprise one or more operation
controls such as buttons. In this example, the control panel 340
comprises an `Off` button 1210, a `Fan On--50%` button 1220, and a
`Fan On--100%` button 1230.
[0060] When a user presses the `Off` button 1210, the driving unit
510 is energized to slide the retractable hood unit 320 into the
housing 310 (if the retractable hood unit 320 was in the extended
position). Furthermore, upon the `Off` button 1210 is pressed, the
ventilation unit 530 and the warning lights 910 can be powered
off.
[0061] When the user presses the `Fan On--50%` button 1220, first
the driving unit 510 is activated to position the retractable hood
unit 320 on its half length (in other words, the retractable hood
unit 320 is extended to 50% from the housing 310). Further, the
ventilation unit 530 is powered to start blowing. In this case, the
ventilation unit 530 can be powered at 50% of its entire power. And
lastly, the warning lights 910 are automatically powered.
[0062] When the user presses the `Fan On--100%` button 1230, the
driving unit 510 is activated to extend the retractable hood unit
320 to its full length (in other words, the retractable hood unit
320 is extended to 100% from the housing 310), the ventilation unit
530 is powered to start blowing, and the warning lights 910 are
powered to illuminate that the assembly 110 is in use and to
indicate its angles and boundaries.
[0063] Those skilled in the art would appreciate that multiple
different buttons can be used, and multiple operating modes can be
assigned to them depending on application.
[0064] The built-in ventilation hood assembly 110 may also comprise
any other circuits, hardware, software, firmware or a combination
thereof to provide the functionality of the disclosed embodiments.
For hardware implementation, the embodiments can be implemented
with processors, controllers, micro-controllers, microprocessors,
