Description

A kind of filter device of range hood

Technical field

The utility model relates to a kind of filter device of range hood.

Background technique

For range hood as electric appliance common in our daily lifes, use is very extensive, is a kind of purification kitchen environment Kitchen appliance, it is mounted on above cooking stove, can be by being harmful to the human body of generating in exhaust gas and cooking process that cooking stove burns Oil smoke siphons away rapidly, and discharge is outdoor, plays the role of purifying air.

Current existing near-suction type oil smoke suction machine mostly uses common single layer orifice-plate type strainer, can be lost if aperture is too small compared with Big air quantity, and easily blocked by greasy dirt；Filter effect weakens if aperture is excessive, and since duct is straight-through, noise outflow is larger, And be mostly stationary structure, it is not easy to clean.

Summary of the invention

Technical problem to be solved in the utility model is a kind of fume-exhausting for being directed to above-mentioned state of the art and proposing Machine filter device.

Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of filter device of range hood, packet Include at least two layers of sieve plate, which is characterized in that wherein at least have one layer of waveform filter plate to rise and fall for section height, the section It is upper to form multiple continuous wave crests and trough, while several filter hole are provided on the waveform filter plate.

Further, the sieve plate further includes at least one layer of cover board, the cover board be lining on the outside of waveform filter plate or Inside is provided with several filter hole on the cover board.

Further, the peaks and troughs of the waveform filter plate can be arcuation, can also be straightway or other.

Further, the cover board filter hole is bar shaped ventilation hole, and the peripheral wall of bar shaped ventilation hole forms flange, is owned The flange direction of ventilation hole is towards inside range hood.

Further, the sieve plate further includes one layer of cover board, and the cover board is entity plate, is lining in waveform filter plate Outside, the cover board and waveform filter plate are spaced certain distance, and periphery forms air inlet.

Compared with prior art, the beneficial effects of the utility model are: waveform increases sieve plate and soot gas Contact area, draught area is bigger compared to plane, and wind loss is smaller, and filter effect is significant, and grease separating degree is high.

Specific embodiment

The utility model is described in further detail below in conjunction with figure embodiment.

Embodiment one

Referring to figs. 1 to Fig. 4, a kind of filter device of range hood, including two layers of sieve plate 1, wherein one layer is section height The waveform filter plate 11 of fluctuating, forms multiple continuous wave crests 111 and trough 112 on the section, and another layer is the lid of plane Plate 12, cover board 12 are lining in 11 outside of waveform filter plate, form wavy gap, while waveform mistake between two layers of sieve plate Multiple filter hole 113 equal in magnitude, equally distributed are provided on filter plate 11 and cover board 12.

To guarantee the good filter effect of the filter device, the aperture of the filter hole be should be as small as possible, and consider processing technology Difficulty, preferably 2~3mm；To avoid incoming air area is too small from causing wind loss excessive, 1 punching rate of sieve plate is answered High as far as possible, i.e. the arrangement in hole is close as far as possible, and similarly, to consider processing technology, center between two holes is preferably 3~4mm away from a, Line-spacing can be made smaller using dislocation arrangement between 113 row of filter hole and row simultaneously, improve punching rate.

This filter device key is waveform filter plate 11, and the shape of dipping and heaving increases filter table and soot gas The surface area of contact makes soot gas by adequately filtering, substantially increases suction along with the filter hole 113 of fine and closely woven arrangement The grease separating degree of kitchen ventilator.

Embodiment two

With reference to Fig. 5, the present embodiment and embodiment one the difference is that: the filter device includes three layers of sieve plate 1, Intermediate one layer is waveform filter plate 11, inside and outside respectively have one piece of plane cover board 12, make-up is fixed, and three layers of sieve plate are provided with Fine and closely woven filter hole 113 carries out three layer filtration to oil smoke, and air quantity has partial loss, but grease separating degree is higher.Meanwhile institute Stating filter device is detachable form, and the structure of three layers of sieve plate 1 is more aesthetically pleasing, easy to clean.

Embodiment three

With reference to Fig. 6, the present embodiment and embodiment one, two the difference is that: the cover board 12 is to be provided with several bar shaped The plate of ventilation hole 121, a trough 112 of the corresponding waveform filter plate 11 of each bar shaped ventilation hole 121, each entity interval Also a wave crest 111 of waveform filter plate 11 is corresponded to, and the peripheral wall of ventilation hole forms flange 122, all ventilation holes Flange direction is towards inside range hood, can preventing the oil on cover board from dripping from bar shaped ventilation hole.

Example IV

With reference to Fig. 7, the present embodiment and embodiment one, two, three the difference is that: the cover board 12 is entity plate, Cover board 12 and waveform filter plate 11 are spaced certain distance, form the air inlet on periphery, and are not provided on the cover board 12 Ventilation hole, whole surface are the materials such as metal or glass, play the condensation to soot gas.

Each technical characteristic of embodiment described above can carry out any combination, for simplicity of description, not to above-mentioned reality Apply each technical characteristic in example it is possible that combination be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.
