Abstract
The utility model discloses an easy dismounting and washing ceiling fume-exhauster, comprising a machine case. The interior of the machine case is provided with a spiral case and a fume collecting hood. The interior of the spiral case is provided with an impeller. The fume collecting hood is provided with an air inlet which is concentric with the air inlet of the spiral case and the impeller. The air inlet is provided with a screen assembly and an air inlet ring. The air inlet of the spiral case is provided with a wind guide ring. The utility model is characterized in that the diameters of the air inlet and the air inlet of the spiral case are greater than the outer diameter of the impeller; the inner diameter of the wind guide ring is smaller or equal to the inner diameter of the impeller. In addition, the connection of the wind guide ring and the spiral case utilizes the magnetic suction function of the magnet. When the impeller of the draught fan and the interior of the fume-exhauster are cleaned and the draught fan is repaired, only one screw is screwed, the rest is rapidly completed by hands. Thus, the operation of the dismounting is easy.
Description
Technical field
The utility model relates to a kind of top-sucking kitchen ventilator, particularly a kind of top-sucking kitchen ventilator of very easily unpicking and washing.
Background technology
Existing top-sucking kitchen ventilator generally is made up of blower fan, spiral case, casing, exhaust fume collecting hood etc., has the fresh air inlet concentric with blower fan on the top board of exhaust fume collecting hood.In order to prevent return air, the bore of the fresh air inlet on the exhaust fume collecting hood must be less than the maximum outside diameter of blower fan.Like this, in the time of need cleaning draught fan impeller, lampblack absorber is inner and needs the maintenance blower fan at lampblack absorber, must be the parts of blower fan front---be that air-intake device and exhaust fume collecting hood disassemble fully, could take out blower fan then keeps in repair and cleans, need the professional to utilize the expensive time of instrument just to open and reinstall, the user through specialized training is not difficult to clean voluntarily for this reason.
Summary of the invention
Technical problem to be solved in the utility model be the exploitation a kind of rational in infrastructure, can prevent that return air is easy to the top-sucking kitchen ventilator of unpicking and washing again.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the top-sucking kitchen ventilator that this is easily removable and washable, include casing, spiral case and exhaust fume collecting hood are installed in the casing, impeller is installed in the spiral case, have air intake vent and the concentric air inlet of impeller on the exhaust fume collecting hood with spiral case, air inlet is equipped with guard assembly and air inlet circle, air-ducting ring is equipped with at the air intake vent place of spiral case, the diameter of air intake vent that it is characterized in that described air inlet and spiral case is greater than the external diameter of described impeller, and the internal diameter of air-ducting ring then is less than or equal to the internal diameter of impeller.
Described air-ducting ring is provided with bearing, is embedded with magnet in the bearing, and air-ducting ring promptly is adsorbed on the spiral case at described spiral case air intake vent place on the plane by magnet.
Described air inlet circle is provided with a radially overhanging lug, and the position relative with this lug has and can hold the through hole that screw passes on the air inlet circle; Correspondingly, the air inlet place of described exhaust fume collecting hood is provided with the nut seat that can hold socket that this lug inserts and can be spirally connected with described screw.
It is the fillet of 2mm～50mm that the inboard design in the porch of described air-ducting ring has R.
The inlet end of described air-ducting ring has oil outlet, and the opening direction of oil outlet points to the air-ducting ring center.
The described air-ducting ring back side forms groove along hoop, and groove is embedded with sealing ring.
Compared with prior art, advantage of the present utility model is: 1, need pull down impeller and clean, when keeping in repair, need not to tear open exhaust fume collecting hood, only need pull down guard assembly, air inlet circle and air-ducting ring and impeller can be taken out, thereby operation be very easy, it is convenient too to install; 2, air-ducting ring adopts magnetic structure with being connected of spiral case, tool free during dismounting, and therefore corresponding constructions such as nut seat or snap seats need be set on the spiral case, so both reduce the difficulty of manufacturing and also improved production efficiency; 3, the location of guard assembly and air inlet circle were finished by an eye-splice structure and a spiro connection structure with only being connected of air inlet, had reduced the difficulty of dismounting equally; Like this, in the time of need cleaning draught fan impeller, lampblack absorber is inner and needs the maintenance blower fan at lampblack absorber, only need back out a screw, all the other can be finished fast all by hand.4, the fillet of air-ducting ring porch design meets hydrodynamics, helps reducing the air intake resistance, improves the suction of range hood; 5, the design of oil outlet opening direction on the air-ducting ring, both can reduce on business the return air that is produced under the too high situation of flue blast altogether flows out sucking the interference and the retardance of air-flow from oil outlet, thereby raising suction can prevent oil outlet effluent stream excessive velocities under this situation again and carries greasy dirt secretly and directly pass oil cleaner screen.6, be embedded with sealing ring in the groove at the air-ducting ring back side, thereby can between air-ducting ring and spiral case, form good sealing, thereby prevent that oil droplet from entering in the cabinet, and sealing is reliable.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As Fig. 1～illustrated in Figure 5, be a preferred embodiment of the present utility model.As Fig. 1～shown in Figure 3, the top-sucking kitchen ventilator that present embodiment is easily removable and washable, include casing 1, spiral case 2 and exhaust fume collecting hood 3 are installed in the casing 1, impeller 4 is installed in the spiral case 2, have the air inlet concentric with the air intake vent of spiral case 2 and impeller 4 on the exhaust fume collecting hood 3, air inlet is equipped with guard assembly 5 and air inlet circle 6, and air-ducting ring 7 is equipped with at the air intake vent place of spiral case 2.The upper end of described guard assembly 5 is enclosed within air-ducting ring 6 ends, is fastened and located by air inlet circle 6 again.The diameter of the air intake vent of air inlet on the exhaust fume collecting hood 3 and spiral case 2 is greater than the external diameter of impeller 4, so that the turnover of impeller 4, the internal diameter of air-ducting ring 7 then equals the internal diameter of impeller 4, so that effectively prevent the influence of return air.Referring to Fig. 4, Fig. 5, air-ducting ring 7 outsides are equipped with four bearing 7a, all are embedded with magnet 8 in each bearing 7a, and air-ducting ring 7 promptly is adsorbed on the spiral case at spiral case 2 air intake vent places on the plane by magnet 8.For reducing the air intake resistance, the fillet that R is 2mm～50mm can be designed in the inboard, porch of air-ducting ring 7, and the radius of corner R in the present embodiment is 12mm.The inlet end of air-ducting ring 7 evenly forms four oil outlet 7b along hoop, and the opening direction of oil outlet 7b points to air-ducting ring 7 centers.Be the good sealing of formation between air-ducting ring 7 and spiral case 2, thereby prevent that oil droplet from entering in the cabinet, air-ducting ring 7 back sides form groove along hoop, and groove is embedded with sealing ring 9.Air inlet circle 6 is provided with a radially overhanging lug 6a, and the position relative with this lug 6a has and can hold the through hole 6b that screw 10 passes on the air inlet circle 6; Correspondingly, the air inlet place of exhaust fume collecting hood 3 is provided with the nut seat 3a that can hold socket that this lug 6a inserts and can be spirally connected with screw 10, is meter attractive in appearance, also is buckled with screw cap 11 on the screw after the assembling 10.
