The high-voltage power supply module of the conventional range hood is usually mounted and disposed in an electric box of the range hood, and supplies power to the electrostatic absorption apparatus through a high-voltage direct current power supply wire. The high-voltage direct current power supply wire usually transmits a high voltage of thousands of volts, and has hidden dangers once it is shorted or short-circuited, or directly contacts with a human body. Such a ventilating hood is disclosed in US 3,785,124 A. The ventilating hood has an ascending exhaust duct equipped with a series of air cleaning and purifying instrumentalities for removing grease, smoke and fumes generated by cooking equipment. Air rising through the duct passes successively through a grease extractor, an electrostatic precipitator, an activated charcoal filter and a deodorizing chemical spray. The grease extractor and precipitator are provided with hot water and detergent washing sprays. The hood has hollow walls containing air supply conduits for fresh air outlets which discharge streams of fresh air for sweeping into the exhaust duct smoky and grease-laden air from the cooking equipment. A power pack is provided which supplies high voltage power to the plates of the electrostatic cleaner cells.

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.

[0026] 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.

[0027] 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.

[0028] 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).

[0029] 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 fwo 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.

[0030] 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.

[0031] The foregoing embodiment is only a preferred embodiment of the present application, the scope of the present invention is defined by the appended claims. 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. In an example which is not part of the claimed invention, 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, in another example which is not part of the claimed invention, Z 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.
