Abstract
The utility model relates to a non-cleaning electrostatic cooking fume removing machine, and the general structure comprises an outer hood shell, an air exhaust fan, and an oil collection groove. The utility model is characterized in that a corona discharge zone is formed in the hood shell, the outer hood shell is formed as a negative plate of the discharge zone, a corona discharge wire with a positive high voltage and an anode plate the same potential as a corona wire are arranged in the shell body, and a small voltage increasing transformer which is arranged in the inner wall of the hood shell provides the positive high voltage. The machine uses a new cleaning mechanism, not only reduces the power consumption of a blower and reduces noise, but also really eliminates the pollution. The utility model does not release the pollution into the atmospheric environment, and is suitable for the social environment protection.
Description
The utility model belongs to the electric device of environmental protection and air cleaning, specially refers to a kind of static flue gas removing machine that avoids cleaning.
Traditional kitchen fume is removed equipment, generally be divided into " directly exhausting type " and " filtration straight-line " two classes, the former is to use blower fan that the oil smoke that produces in the cooking process is directly discharged in outdoor atmosphere, its advantage is that equipment is simply cheap, but being actually inreal the removing pollutes, but kitchen pollution is married again to the ambient atmosphere pollution, be a kind of secondary pollution to environment.The another kind of straight-line that filters, be by filtration such as filter screen and active carbon with the polluter in the oil smoke is filtered adsorbent and absorption is fallen with oil flue waste gas, cleaned air after will filtering then is directly in indoor discharging, it can not cause secondary pollution, western developed country all adopts these class methods and equipment at present, but shortcoming is the equipment cost height, needs often to change sorbing material and regular cleaning and filtering net.The smoke extractor that China's domestic production is sold, it nearly all is direct exhausting type, this is not only because equipment price is low, more be because Chinese meal when culinary art uses edible oil many, the oil smoke amount is big, more need often to clean, filter straight-line if adopt, adsorbent and screen pack also more will often be changed, just can keep the effect of removing oil smoke, so not only bother but also uneconomical, thereby seek a kind of cheap, the method and the device that avoid the removal fume pollution that cleans again just become and solve an especially very necessary behave of Chinese meal kitchen fume pollution of kitchen environment.
The purpose of this utility model is in order to overcome the weak point separately of two class flue gas removing devices in the present kitchen, design a kind of to environment both non-secondary pollution, can make again price lower, need not change adsorbent, need not clean a kind ofly exempt to clean the static flue gas removing machine by what the electrostatic precipitation principle was made.
The utility model relies on following technical proposals to realize, a kind ofly exempt to clean the static flue gas removing machine, total structure comprises outer casing, ventilating fan, oil trap, its principal character is to form corona discharge region in case, housing case is as the minus plate of region of discharge, the corona discharge wire that enclosure interior is provided with positive high voltage reaches and the idiostatic positive plate of corona wire, region of discharge air flow inlet portion, be mesh shape metal cover plate, ventilating fan is equipped with in air stream outlet portion, provides positive high voltage by the small-sized step-up transformer of ancient piece of jade, round, flat and with a hole in its centre setting in the case.
When the high pressure that provides reaches 30,000 volts of left and right sides positive high voltages, form corona discharge between positive plate and the minus plate, make the smoke particle in space charged, the smoke particle of positively charged drifts about to minus plate under the highfield effect, after arriving minus plate, discharge institute's lotus positive electricity, and accumulate on the minus plate, when the oil smoke amount of being assembled is abundant, these oil smoke aggregations that are the viscous liquid shape just flow to oil trap under the gravity effect, and the position of oil trap is in the lowest part that the over body case that tilts hanging is arranged slightly.
By this device, after cooking fume and burning oil smoke discharge ionization removal, clean air is directly in indoor discharging, its exhaust outlet can be identical with the air inlet bore even bigger, thereby overcome traditional exhausting type smoke exhaust ventilator and be subjected to exhaust diameter and smoke pipe length, restrictions such as geometry, have to increase power of fan, to increase capacity, also brought the harm that has increased noise when increasing the blower fan power consumption, this device has not only reduced the blower fan power consumption owing to adopted new removing oil smoke mechanism, has reduced noise, and be that real the removing polluted, rather than marry again to pollute and give atmospheric environment.Promoting the use of of it helps the protection of social environment, has substantive progressive.
Further specify embodiment below in conjunction with accompanying drawing:
Description of drawings:
Fig. 1 is an overall construction drawing of exempting to clean the static flue gas removing machine;
Fig. 2 is an AA cross-sectional view in Fig. 1 structure;
Fig. 3 is the structural representation of corona wire in the range hood over body case;
Fig. 4 is the another kind of embodiment of range hood structure.
Wherein, outer casing 1 is an external packing body of forming range hood with the planar shaped metallic plate; Mesh shape metal cover plate 2, as the air flow inlet part, corona wire parts 3, detailed structure provides at Fig. 3, its both side ends is an insulator 3.1, can make of the polytetrafluoroethylene (PTFE) of high insulating property, and the spring section 3.2 of the corona wire that symmetry is arranged is connected with corona wire part 3.3.Oil trap 4 is in the extreme lower position of case, and high voltage package 5 claims step-up transformer again, it is the semiconductor step-up transformer that is operated in the 15K hertz, it can provide the positive voltage up to 30,000 volts, and insulator 6 is supported between the minus plate of band positive plate 8 of malleation and zero potential, and insulating effect electrifies.Two hooks 7 of limit portion are with range hood and wall mounted.Another kind of embodiment is illustrated in Fig. 4, it is in removing the general construction of oil smoke region of discharge to be divided into a plurality of parallel zonules, a corona wire is settled in each zonule, these corona wires serve as again and are the anode in the discharge process, the actual effect of the embodiment of this many region of discharges shows, its efficient of removing oil smoke is increased to present 97% by 90% of preceding a kind of embodiment, this is because many region of discharges are more abundant to the ionization of space oil grit.
