DETAILED DESCRIPTION
[0025] In order to make the objective, solution, and beneficial effects of the present application
more clear and comprehensible, the present application is further described with reference
to the accompanying drawings and the preferred embodiments.
Embodiment 1
[0026] The present application provides an embodiment of a range hood, including a fan,
a filter net 5, an oil cup 6, a chassis 3, a smoke collection cover 4, a decorative
cover, an electrostatic absorption apparatus 1, a high-voltage power supply module
2 that is used to supply power to the electrostatic absorption apparatus 1 directly,
and an accommodation cavity 7 adapted to accommodate the electrostatic absorption
apparatus 1, as shown in FIGs. 1 and 2. The fan is disposed in the chassis 3. The
oil cup 6 is fixed on a bottom end of the smoke collection cover 4. The accommodation
cavity 7 is located between the chassis 3 and the smoke collection cover 4. The accommodation
cavity 7 is provided with a bottom air inlet and a top air outlet, as shown in FIG.
3. Specifically, the fan is located above the top air outlet of the accommodation
cavity 7, and the filter net 5 is located below the bottom air inlet of the accommodation
cavity 7.
[0027] The electrostatic absorption apparatus 1 includes an absorption electrode plate and
an ionization wire. There are two electrostatic absorption apparatuses 1, and the
two electrostatic absorption apparatuses 1 are arranged in the accommodation cavity
7 in parallel. In FIG. 3, the left electrostatic absorption apparatus 1 is accommodated
in the accommodation cavity 7, but the right one 1 is not accommodated yet. The structures
of the electrostatic absorption apparatus 1 are the same and the installation positions
thereof can be exchanged.
[0028] The accommodation cavity 7 is cuboid, as shown in FIG. 3, the bottom air inlet is
located on the bottom surface of the cuboid accommodation cavity 7, and the top air
outlet is located on the top surface of the cuboid accommodation cavity 7. The accommodation
cavity 7 includes a placement opening and a rear wall gap disposed opposite to each
other. The placement opening is located on a side surface of the accommodation cavity
7. The high-voltage power supply module 2 blocks the rear wall gap. The high-voltage
power supply module 2 is used as a partial wall body of the accommodation cavity 7,
and specifically, the high-voltage power supply module 2 is used as a rear wall of
the accommodation cavity 7. The electrostatic absorption apparatus 1 is disposed to
adapt to penetrate through the placement opening to be placed in the accommodation
cavity 7 in a horizontal direction toward the rear wall of the accommodation cavity
7, till the electrostatic absorption apparatus 1 is connected to the high-voltage
power supply module 2 by insertion, as shown in FIGs. 1 and 2. The decorative cover
(not shown) is placed on the smoke collection cover 4 so as to shield the chassis
3 and the electrostatic absorption apparatus 1.
[0029] The high-voltage power supply module 2, also called as a high-voltage generator,
has an English abbreviation HVPS (high voltage power supply). The high-voltage power
supply module 2 includes a mains power supply wire that is used to supply power to
the high-voltage power supply module 2. In this embodiment, the mains power supply
wire provides a 220v alternating current to the high-voltage power supply module 2.
The high-voltage power supply module 2 supplies power to the electrostatic absorption
apparatus 1 by means of insertion connection, that is, when the high-voltage power
supply module 2 and the electrostatic absorption apparatus 1 are connected by insertion,
the high-voltage power supply module 2 and the electrostatic absorption apparatus
1 are electrically connected, and the high-voltage power supply module 2 supplies
a high-voltage direct current required by operation of the electrostatic absorption
apparatus 1 to the electrostatic absorption apparatus 1 through the insertion position.
The rear side wall of the high-voltage power supply module 2 is exposed outside and
faces an installation wall (in this embodiment, the range hood is fixed on the installation
wall).
[0030] The electrostatic absorption apparatus 1 is provided with a plug portion, the high-voltage
power supply module 2 is provided with a socket portion adapted to connect to the
plug portion by insertion. Specifically, the plug portion of the electrostatic absorption
apparatus 1 includes a ground electrode plug portion 9, an absorption electrode plug
portion 10, and an ionization electrode plug portion 11 sequentially arranged, as
shown in FIG. 5. The absorption electrode plug portion 10 is electrically connected
to the absorption electrode plate of the electrostatic absorption apparatus 1. The
ionization electrode plug portion 11 is electrically connected to the ionization wire
of the electrostatic absorption apparatus 1. An insulation isolation wall is disposed
between the ground electrode plug portion 9 and the absorption electrode plug portion
10, and two parallel insulation isolation walls are disposed between the absorption
electrode plug portion 10 and the ionization electrode plug portion 11. The high-voltage
power supply module 2 is provided with three socket portions that are one-to-one corresponding
to the ground electrode plug portion 9, the absorption electrode plug portion 10,
and the ionization electrode plug portion 11 of the electrostatic absorption apparatus
1. Each socket portion has the same structure and includes insertion connection spring
8. For example, the socket portion that is connected to and cooperates with the ground
electrode plug portion 9 by insertion shown in FIG. 4 includes two insertion connection
springs 8 that have a gap there-between. When the ground electrode plug portion 9
is inserted into the gap, the two insertion connection springs 8 are deformed elastically
to be far away from each other (the gap become large), the ground electrode plug portion
9 is held by the two insertion connection springs 8, and the high-voltage power supply
module 2 and the electrostatic absorption apparatus 1 are connected by insertion.
At this time, if a user extracts the electrostatic absorption apparatus 1 from the
accommodation cavity 7, the ground electrode plug portion 9 is separated from the
two insertion connection springs 8, and the two insertion connection springs 8 are
recovered from the elastic deformation. It should be noted herein that, since there
are two electrostatic absorption apparatuses 1, the high-voltage power supply module
2 has six socket portions in total correspondingly.
[0031] When the fan is working, an air flow flows through the filter net 5 and then into
the bottom air inlet of the accommodation cavity 7, then flows through the electrostatic
absorption apparatus 1 and then out of the top air outlet of the accommodation cavity
7, and is finally discharged from the fan.
[0032] The foregoing embodiment is only a preferred embodiment of the present application,
and other embodiments can be deduced by adding, deleting, altering or replacing some
technical features. For example, the mains power supply wire that is used to supply
power to the high-voltage power supply module can be replaced as the low-voltage direct
current power supply wire, and one end of the low-voltage direct current power supply
wire is electrically connected to the high-voltage power supply module, and the other
end is electrically connected to an electric box of the range hood. For example, the
electrostatic absorption apparatus is provided with a socket portion and the high-voltage
power supply module is provided with a plug portion adapted to connect to the socket
portion by insertion. In addition, the specific structures of the plug portion and
the socket portion and the cooperation manner are not limited to this embodiment,
and similar technical solutions of insertion connection in the prior art may also
be referred to, for example, the cooperation structure of the power supply plug and
the socket.
Embodiment 2
[0033] The present application further provides an embodiment of a housing component of
a range hood that includes a housing and a high-voltage power supply module adapted
to supply power to an electrostatic absorption apparatus.
[0034] The housing includes an accommodation cavity adapted to accommodate the electrostatic
absorption apparatus, and the high-voltage power supply module is used as a partial
wall body of the accommodation cavity.
[0035] The high-voltage power supply module is fixed to the housing. The high-voltage power
supply module includes a socket portion that is used to supply power to the electrostatic
absorption apparatus.
[0036] If an electrostatic absorption apparatus is installed into the accommodation cavity
of the housing component, one end surface of the electrostatic absorption apparatus
is attached to the high-voltage power supply module, and the electrostatic absorption
apparatus and the high-voltage power supply module are connected by insertion. Of
course, in order to realize the insertion connection with the housing component, the
corresponding electrostatic absorption apparatus needs to be provided with a plug
portion matching the socket portion of the housing component.
[0037] The foregoing embodiment is only a preferred embodiment of the present application,
and other embodiments can be deduced by adding, deleting, altering or replacing some
technical features. For example, the housing may also include a chassis and a smoke
collection cover, and the accommodation cavity is located between the chassis and
the smoke collection cover. Furthermore, for example, the high-voltage power supply
module may also be disposed in the housing, and specifically, the high-voltage power
supply module is attached onto the inner wall of the housing. Furthermore, for example,
the housing may also include a gap portion, and the high-voltage power supply module
blocks the gap portion.
[0038] The members in different embodiments can be combined in any feasible manner, so as
to realize the objective of the present application.
[0039] It should be additionally noted that, the present application shall not be understood
to be limited to the foregoing embodiments, but shall be understood to cover all possible
situations determined according to the claims and the disclosure of the specification
of the present application. Therefore, any simple alteration, equivalent change or
