Fig. 1-4 is please referred to, the present invention provides a kind of technical solution: a kind of cell apparatus for treating cooking fume, including outdoor processing
Device 100 and indoor processing unit 200, outdoor processing device 100 include escape pipe 120, swimmer's pool 140, reservoir 180, mistake
Screen pipe 150, and outdoor processing device are provided with below chimney filter 150 and downstream plate 170, reservoir 180 and plate 170 downstream
100 left end is separated into multiple pipelines by plate 170 downstream, and the right end of outdoor processing device 100 is provided with discharge pipe, in discharge pipe
Blower 110 is installed, the lower left of discharge pipe is provided with swimmer's pool 140, water pump 141 is equipped in swimmer's pool 140;
Indoor processing unit 200 includes range hood 220, blast pipe 210 and bellows 230, and range hood 220 passes through blast pipe
210 connection bellows 230, bellows 230 include, cooking fume-collecting bottle 240, filter plate 270 and pulling plate 260, filter plate 270 are fixed respectively
Blast pipe 210 and bellows 230 are connected, pulling plate 260 is mounted on the front side of filter plate 270, and is provided with sliding rail below pulling plate 260
261, sliding rail 261 is fixedly connected with bellows 230, and cooking fume-collecting bottle 240 is mounted on 230 bottom end of bellows, and the bottom end of bellows 230 is also solid
Surely it is connected with communicating pipe 190, bellows 230 with outdoor processing device 100 by being fixedly connected communicating pipe 190.
In the present embodiment, it is to be understood that the blower 110 in escape pipe 120 is ultra-large type blower 110, is passed through
The devices such as steel pipe are fixed on escape pipe 120, and the watt level of blower 110 is made to change with the difference of community user, if cell
User is more, then the power of corresponding blower 110 is larger, and the suction of generation is also just big, otherwise the power of blower 110 will be compared with
It is small;And the apparatus for treating cooking fume concentrates timing open work, and such as: 5 points to 8 points, 10 points to 14 points, 16 points to 20 points, whenever
The cooking time section of community user is reached, the relevant staff of the cell opens apparatus for treating cooking fume, works as apparatus for treating cooking fume
When start-up operation, the wind in escape pipe 120 is started to work, and generates super large air draught power, and pass the air draught power by associated conduit
Water pump 141 into the indoor processing unit 200 of every household, while in swimmer's pool 140 is started to work, and water is extracted to water storage
The substance for being conducive to have smoking to adsorb and degrade to oil smoke can be added in pond 180, and in the swimmer's pool 140 or reservoir 180;
It is understood that doing the drawstring 250 for pulling 230 right end of bellows before meals, drawstring when the user in cell needs to cook
Pulling plate 260 inside 250 drive bellows 230 moves right on sliding rail 261, so that blast pipe 210 is opened, so that blast pipe
210 are connected with communicating pipe 190, and the suction change that blower 110 generates is transmitted to blast pipe 210, blast pipe 210 and range hood 220
Be connected, the oil smoke generated when cooking will enter range hood 220 under the action of suction, and by blast pipe 210 be connected to
Pipe 190 enters in outdoor processing device 100, when oil smoke reaches in outdoor processing device 100, in the suction of blower 110
Under, oil smoke is mobile to 120 direction of escape pipe along pipeline, and in this process, the water in reservoir 180 was entered by outlet
In chimney filter 150, due to opening up hole on screen pipe 150, the water in screen pipe 150 will drip with hole, will be oily in pipeline
Greasy dirt granular absorption in cigarette, the water droplet for adsorbing oil smoke are fallen on plate 170 downstream, and since plate 170 downstream is incline structure,
So be fallen into the pipeline of bottom, and mistake when the water droplet that adsorb oil smoke and become sewage will quickly glide along plate 170 downstream
Chimney filter 150 is provided with multiple with plate 170 downstream, and oil smoke can be adsorbed a large amount of oil smoke in the process of running, to be cleaned, purifies
The oil smoke crossed then sucks escape pipe 120 under the suction of blower 110, and excludes from escape pipe 120, it is to be understood that
The height of escape pipe 120 is higher than the universal height of cell floor, when oil smoke discharge, fumes peculiar smell can be effectively prevent to enter small
Area;Sewage can flow into relevant sewage treatment company from the pipeline on 140 top of swimmer's pool simultaneously, to be handled;And when small
Area user finishes after meal, pulls the drawstring 250 of 230 left end of bellows, pulling plate 260 can be made to transport function to the left by sliding rail 261, closes
Blast pipe 210, so that not generating suction in exhaust fume collecting hood.
In the present embodiment, by using the mode of cell centralized processing oil smoke, oil smoke processing dress in user room is set
Set with outdoor processing device 100, the oil smoke of a cell is focused on, to a certain extent instead of existing fume-exhausting
Machine, and concentrate and carry out oil smoke processing, it saves using electric power caused by range hood, reduces the economic damage of the country and people
It loses, improves economic benefit;Oil smoke is then exhausted from the pollution for also significantly reducing oil smoke to air by purification, protects environment.
Further, water-supply-pipe 130 is connected on water pump 141, the other end of water-supply-pipe 130 is fixedly connected with reservoir 180,
Water pump 141 connects reservoir 180 by water-supply-pipe 130.
Referring to Fig. 1, in the present embodiment, water pump 141 by water-supply-pipe 130 by the water in swimmer's pool 140 extract to
In reservoir 180, used for filter pipe;It is understood that swimmer's pool 140 is deeper well, it is possible to provide sufficient water;Work as depth
When water level in pond 140 is higher, water pump 141 is worked normally, when the water level in swimmer's pool 140 is lower, water pump 141 extract less than
When water, it will automatically power off, stop working, avoid the idle running of water pump 141 from causing itself to damage, present embodiment provides a kind of water pump
141 principles automatically powered off: hydraulic pressure sensor of the installing with processing chip, power supply circuit in the internal pipeline on water pump 141
Upper that relay is housed, when normal pumping, hydraulic pressure sensor experiences normal hydraulic pressure, any reaction is not generated, when swimmer's pool 140
Middle water level is lower, and when can not be extracted into water, inside water pressure sensor experiences abnormal low level hydraulic pressure, will send and believe to relay
Number, relay senses the connection of disconnection water pump 141 and circuit after this signal, to automatically power off.
