[0045] Embodiment 1

[0046] This embodiment provides a specific implementation manner of an oil fume purifier, as Figure 1 shown, including: an air inlet 1, an electric purification chamber 4, a heat conduction structure, an oil fume collection box 5 disposed below the electric purification chamber 4, and a pipe 3 connecting the air inlet 1 and the electric purification chamber 4.

[0047] The electric purification chamber 4 is communicated with the air inlet 1 through the pipe 3; the heat conduction structure is disposed at the air inlet 1 and extends into the electric purification chamber 4 through the pipe 3.

[0048] The heat conduction structure includes at least one heat conductor 2, and at least one of the heat conductors 2 extends from the air inlet 1 into the electric purification chamber 4. The number of heat conductors 2 can be set to one, or two, three or more.

[0049] The heat conductor 2 includes a first portion 21 disposed at the air inlet 1 and a second portion disposed in the electric purification chamber 4. In order to increase the contact area between heat and the first portion 21, so as to fully absorb the heat at the air inlet 1 and improve the energy utilization rate, as Figure 2 shown, the first portion 21 is spirally arranged at the air inlet 1. As a preferred implementation manner, the length extension direction of the first portion 21 is parallel or coplanar with the plane where the air inlet 1 is located.

[0050] Among them, the first portion 21 extends from one end of the air inlet 1 to the other end, and the first portion 21 has a relatively large length, which can increase the contact area between heat and the first portion 21, so as to fully absorb the heat at the air inlet 1 and improve the energy utilization rate.

[0051] As a preferred implementation manner, two heat conductors 2 are provided, and both of the two heat conductors 2 extend into the electric purification chamber 4, which can not only improve the energy utilization rate but also does not affect the normal air intake at the air inlet 1.

[0052] A dust collecting plate 6 is disposed in the electric purification chamber 4, and at least one of the heat conductors 2 is wound around the dust collecting plate 6. The heat conductor 2 can melt the oil stain on the dust collecting plate 6, preventing the oil stain from adhering to the dust collecting plate 6 and affecting the purification efficiency of the electric purification chamber 4. After the oil stain melts in the electric purification chamber 4, it flows into the oil fume collection box 5. During cleaning, the oil fume collection box 5 can be disassembled and cleaned, which is convenient for cleaning.

[0053] The dust collecting plates 6 are spaced apart from each other in the vertical direction. As Figure 3 shown, the heat conductor 2 is wound around each dust collecting plate 6 in a wavy shape, which can fully melt the oil stain on the dust collecting plate 6.

[0054] At least one of the heat conductors 2 is wound around the dust collection plate 6 and then extends into the fume collection box 5. At least one of the heat conductors 2 extends downward into the fume collection box 5 within the electric purification chamber 4. The melted oil stains on the dust collection plate 6 flow along the heat conductor 2 into the fume collection box 5, with a compact structure. In this embodiment, there are two heat conductors 2. One heat conductor 2 is wound around the dust collection plate 6, and the other heat conductor 2 directly extends into the fume collection box 5. The heat conductor 2 wound around the dust collection plate 6 converges with the other heat conductor 2 and then extends into the fume collection box 5. The melted oil stains on the dust collection plate 6 flow onto the heat conductor 2 and then flow along the heat conductor 2 into the fume collection box 5.

[0055] In this embodiment, the heat conductor 2 is arranged at the axial center position of the pipeline 3. The heat conductor 2 can dissipate heat to the surroundings within the pipeline 3, with uniform heat dissipation, thereby melting the oil stains adhering to the inner wall of the pipeline 3.

[0056] The heat conductor 2 in this embodiment is in a strip structure and can be a heat conduction pipe or a heat conduction strip. During the processing, the first part 21 of the heat conductor 2 is bent and wound into a spiral shape, and the first parts 21 of the two heat conductors 2 are arranged alternately.

[0057] When the range hood is in use, due to cooking, a great deal of heat will be generated at the air inlet 1. By arranging a heat conduction structure at the air inlet 1, the heat at the air inlet 1 is transferred into the electric purification chamber 4, making full use of the heat at the air inlet 1, improving the energy utilization rate, and the heat transferred into the electric purification chamber 4 can melt the oil stains in the electric purification chamber 4, preventing the oil stains from adhering to the electric purification chamber 4 and affecting the purification efficiency of the electric purification chamber 4. Since the heat melts the oil stains into oil droplets, it is also convenient to clean the electric purification chamber 4.

[0058] As the first alternative embodiment of the above embodiment, the pipeline 3 is not provided, the air inlet 1 is directly connected to the electric purification chamber 4, and the heat conduction structure is arranged at the air inlet 1 and extends into the electric purification chamber 4.

[0059] As the second alternative embodiment of the above embodiment, the fume collection box 5 is not provided, and the oil stains melt in the electric purification chamber 4 and flow to the bottom of the electric purification chamber 4. Only the bottom of the electric purification chamber 4 needs to be cleaned.

[0060] As the third alternative embodiment of the above embodiment, the heat conduction structure includes a heat conduction net with a large contact area arranged at the air inlet 1 and a heat conduction wire connected to the heat conduction net. The heat conduction wire extends into the electric purification chamber 4.

[0061] As a third alternative embodiment of the above-described embodiment, a plurality of heat conductors 2 are provided, and one or more of the heat conductors 2 are wound around the dust collecting plate 6 and then extend into the oil fume collecting box 5, and the melted oil stains flow into the oil fume collecting box 5 along the heat conductors 2.

[0062] Obviously, the above embodiments are merely examples for clear illustration and are not limitations on the embodiments. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the embodiments here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
