Abstract
The invention provides a rotary filter screen of a range hood and belongs to kitchen electrical equipment. The filter screen comprises a docking conical mesh enclosure, wherein the centers of the upper port and lower port of the mesh enclosure are respectively provided with a bearing which is matched with a shaft body connected with a rang hood oil cup and an equipment cabinet; and each bearing is connected to the mesh enclosure through a bearing support, the upper port of the mesh enclosure is provided with a fan blade around the bearing. The filter screen provided by the invention has the advantages that the filter screen can rotate slowly when the rang hood is in work, thereby ensuring the oil gas to be in full contact with the filter screen, improving the gas-oil separation effect, the reducing the dropping difficulty of the minor diameter oil drop on the filter screen and further improving the cleanliness of the filter screen.
Description
Affiliated technical field
The present invention relates to kitchen appliance equipment, especially a kind of Chinese style range hood especially, is its filter screen.
Background technology
Range hood is a kind of kitchen appliance equipment of comparatively popularizing, and is used for discharging the oil smoke that the cooking stove cooking process is produced.With the Chinese style range hood is example, and in the mist extractor process, oil smoke will carry out the process of an Oil-gas Separation at the filter screen place of range hood, pollute to avoid oil-containing gases directly to enter atmosphere; In this process, oil gas is through at least one metafiltration net, and at this moment, oil droplet will condense on filter screen, and behind water conservancy diversion, is dropped in the lubricating cup of filter screen below; Yet; Because present range hood filter screen is fixed, in the oil smoke uphill process, a part of oil-containing gases directly passes from the mesh of filter screen; Can't take place fully to contact with filter screen; Oil molecule in this part oil gas just can't be adsorbed on screen surface, and therefore, its filter effect is not good enough; On the other hand, when oil droplet was attached on the filter screen, because the viscosity between oil droplet and the filter screen, the less oil droplet of diameter was difficult to drip in lubricating cup along filter screen, and the time one is long, just freezes solidly on the filter screen, was difficult to remove.
Summary of the invention
To the problems referred to above; The object of the present invention is to provide the rotary filter screen of a kind of range hood; This filter screen can slowly rotate when range hood is worked, thereby oil gas is fully contacted with filter screen, improves oil gas separation; And can reduce the whereabouts difficulty of minor diameter oil droplet on filter screen, thereby improve the cleannes of filter screen.
The technical solution adopted for the present invention to solve the technical problems is: the rotary filter screen of this range hood comprises a guard in the form of a truncated cone; Two port central authorities up and down of this guard respectively establish the bearing that an axis body that links to each other with rack with the range hood lubricating cup matches; Said bearing is connected to said guard by the support of bearing, is provided with flabellum around said bearing on the port of said guard.
Further, said flabellum is connected between this bearing and the guard as the support of bearing of the central bearing of said guard port.
Further, said guard, bearing, the support of bearing, flabellum are one-body molded.
Further, the quantity of said flabellum is more than 4 or 4.
Beneficial effect of the present invention is: after having adopted this rotary filter screen on the Chinese style range hood; Below filter screen, aspirate in the process of oil smoke at fan; The flabellum that air-flow will promote filter screen slowly rotates; Thereby make whole filtering net do slowly rotation, then guard will take place to contact more fully with oil smoke, thereby improve its oil gas separation; In addition, because the rotation of filter screen, the oil droplet that is adsorbed on the guard surface will receive a less action of centrifugal force, and this centrifugal force will balance out a part of absorption affinity between oil droplet and the guard, thereby promote that oil droplet hurtles down, and drip the oil-feed cup.
Description of drawings
Fig. 1 is the structural representation of Chinese style range hood.
Fig. 2 is the vertical view of an embodiment of the rotary filter screen of this range hood.
The schematic perspective view of Fig. 3 Fig. 2 embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
In Fig. 1, showed the structure of Chinese style range hood, it includes rack 1, is provided with ventilating duct 2 in this rack 1; Be provided with fan 3 in the ventilating duct 2, this fan 3 suction air that can make progress, fan 3 belows connect a lubricating cup 5 through axis body 15; This lubricating cup top is provided with filter screen 4, is aspirated in the uphill process at oil smoke, will pass this filter screen 4; In this filter screen 4, the oil droplet in the oil smoke is attached to filter screen 4 surfaces, finally falls in the lubricating cup 5.
Fig. 2-Fig. 3 then shows an embodiment of the rotary filter screen of this range hood, in this embodiment, comprises a guard 41 in the form of a truncated cone; Two port central authorities up and down of this guard 41 respectively establish the bearing 43 that an axis body 15 that links to each other with rack 1 with range hood lubricating cup 5 matches; Said bearing 43 is connected to said guard 41 by the support of bearing 44, is provided with four flabellums 42 around said bearing 43 on the port of said guard 41, and said flabellum 42 directly links said bearing 43 and guard 41; Therefore; In the port of said guard 41, the support of bearing 44 can omit, and is directly supported by said flabellum 42 conducts.
The rotary filter screen of above-mentioned range hood, said guard 41, bearing 43, the support of bearing 44, flabellum 42 are one-body molded.
After having adopted this rotary filter screen on the Chinese style range hood; Below filter screen 4, aspirate in the process of oil smoke at fan 3; The flabellum 42 that air-flow will promote filter screen 4 slowly rotates; Thereby make whole filtering net 4 do slowly rotation, then guard 41 will take place to contact more fully with oil smoke, thereby improve its oil gas separation; In addition, because the rotation of filter screen 4, the oil droplet that is adsorbed on guard 41 surfaces will receive a less action of centrifugal force, and this centrifugal force will balance out a part of absorption affinity between oil droplet and the guard 41, thereby promote that oil droplet hurtles down, and drip oil-feed cup 5.
