Description

Separable exhauster for removing cooking fume

System of the present invention is relevant with smoke exhaust, more detailed it, refer to a kind of disassembly and assembly smoke exhaust easily especially, people can its bottom plate of free-hand disassembly and assembly and fan protect casket, be convenient to quick assembly and disassembly and thoroughly clean.

Generally commonly use the bottom plate of smoke exhaust and fan thereof and protect that casket all welds or spiral shell is located on the clamshell, dismounting is inconvenience very, only can mat during cleaning stand on the stool and its surface and oil contaminant is removed, but the grease that accumulates on its inside especially flabellum is then had no way out with cleaning agent.The professional be must transfer to and systematic disassembly, cleaning and assembling done, quite uneconomical.Especially can't do in good time washing regularly because of its inside, can cause fault to take place, even damage.

Main purpose of the present invention is: the smoke exhaust that a kind of structurally easy accessibility is provided, making its bottom plate and fan protect casket all can dismantle fast easily, and after the tank that can place the kitchen thoroughly cleans, assembling fast voluntarily, reach and remove grease at any time, keep the cleaning of smoke exhaust, make smoke exhaust give full play to due usefulness.

A kind of separable exhauster for removing cooking fume of the present invention, it comprises that a clamshell contains roof, two sidewalls, front and back sidewall and bottom plate, is provided with extraction fan and motor and at least one corresponding exhaust outlet more than one in this smoke exhaust at least.It is characterized in that: this smoke exhaust have in addition a fan protect casket and above-mentioned bottom plate all utilization activity fastener can free-handly tear group easily open.

Wherein, the movable fastener of bottom plate is that a kind of carbine bolt comprises one " L " type bolt, and a horizontal barb is arranged at the top, and the sagging button of afterbody is also with torsionspring and on angle of cut place is coupling a rectangle slotted eye appropriate location in length and breadth; Other has two oblique sheet snap closes to be fixedly arranged on identical with above-mentioned rectangular channel hole size and is fixedly arranged in two rectangular channels in addition of clamshell two inside sidewalls lower ends, for the usefulness of above-mentioned carbine bolt engaging.

Wherein, it is that one group of " U " type is beaten to buckle and is fixedly arranged on fan and protects around the casket that fan protects the movable fastener of casket, comprises a driving lever, " U " type clasp and a torsionspring; This torsionspring system is wound in this driving lever and is located in fan simultaneously and protects casket precalculated position on every side, and the opening part of " U " type clasp then is located in the centre of this driving lever; Other has one group of relative hook sheet to be fixedly arranged on the lip limit outside that the clamshell roof slightly is " 8 " font top cover, the usefulness of beating fastening for this " U " type.

Advantage of the present invention is: simple in structure, easy to use, assembly and disassembly is easy, even the layman also can tear group open voluntarily, help cleaning at any time grease, to keep its sanitation and hygiene, therefore the service efficiency of smoke exhaust can be improved, and its service life can be prolonged.

Now details are as follows to lift preferred embodiment and conjunction with figs.:

See also shown in Figure 1, a kind of separable exhauster for removing cooking fume of the present invention, main system comprises that by a rectangle clamshell 10 roof 11, two sidewalls 12,13, a rear wall 14, a front side wall 15, a bottom plate 20, two fan 30a, 50b, two motor 40a, 40b and one slightly are " 8 " font fan and protect casket 50 and formed.Wherein bottom plate 20 slightly rectangular around crimping core epirelief, and open circular opening 20a, the 20b of projection around two in the appropriate location, to protect on the casket 50 two cylinder 50c, 50d chimeric on it for the suction opeing of fan and air feed fan, and its bottom plate 20 assembles two carbine bolts 21 symmetry and form two sheet holder 22a, 22b as the usefulness that is sticked in relevant snap close 111 on the clamshell in its leading edge each other near the trailing edge place.Flabellum 30a, the 30b of said fans is respectively that spiral shell is located on the central rotating shaft of associated motor 40a, 40b, is fixedly arranged under the clamshell roof 11 end more respectively, and its switch then is positioned at outside the clamshell front side wall 15 side to control its keying.It is one slightly to be " 8 " font structure that fan protects casket 50, on the hook sheet 122 of four " U " type hasp, 51 fixed top wall, 11 lower ends around investing with it after packing into fan, for fan forms tight protective, in case the immersion of grease.Slightly be fovea superior around circular hole 50a, the 50b of its cylindric lower end, its bore 50a, 50b are consistent with circular opening 20a, 20b on fan 30a, 30b and the bottom plate 20, thus make the oil smoke can be by smooth sucking-off, unlikely obstruction.

See also shown in Figure 2ly, this carbine bolt 21 is to establish one " L " type bolt 212 by axle in the rectangle slotted eye 211, is attachedly formed with torsionspring 214, and this spring 214 is to twine and be fixed in axle to follow closely on 213.Be somebody's turn to do the top one-body molded one horizontal barb 212a of " L " type bolt 212, again the surface that an one-body molded button 212b exposes bottom plate 20 edges in its afterbody lower end.And relative position respectively sets firmly oblique sheet snap close 111 in a rectangular channel 111a in lower end, clamshell 10 two side, so when " L " type bolt 212 stretched in the rectangular channel 111a, the pressure of its horizontal barb 212a mat spring can firmly be sticked on the snap close 111.Otherwise if to push away the button 212b that is exposed to bottom plate 20 edges on free-hand, make the 212 mat leverages of " L " type bolt, revolution one suitable angle, its barb 212a throws off naturally, and makes bottom plate 20 can take off (seeing also shown in Figure 1) easily on clamshell 10.Edge outstanding two slightly rectangular sheet holder 22a, 22b insert on the lip limit of turning in front side wall 15 lower edges earlier when assembling before the bottom plate 20, make bottom plate 20 obtain enough supports.

See also shown in Figure 3, wherein " U " type hasp 51 is fixedly arranged on the both sides that fan protects casket 50, comprise that an end is located in fan and protects driving lever 511 and " U " type clasp 512 on casket 50 edges, its opening part is located in driving lever 511 centres, and another torsionspring 513 is fastened on driving lever 511 front end axles nail.For cooperating " U " type hasp, other has one group of relative hook sheet 122 to be fixedly arranged on 123 outsides, lip limit that clamshell 10 roofs slightly are " 8 " font top cover, and pastes the elastic caoutchouc packing admittedly in these 123 inboards, lip limit, so fan protects casket 50 after assembling, to be very tight, and prevent the oil smoke seepage.

The present invention is in when assembling, earlier fan protected casket 50 and is sleeved on two fan 30a, 30b and matches with lip limit 123 that roof 11 lower ends slightly are " 8 " font top cover, one by one " U " type hasp is fastened on the hook sheet 122 and can firmly makes up again.Inferior 132 upper ends, lip limit of turning in front side wall 15 lower edges that bottom plate 20 trailing edge sheet holder 22a, 22b are inserted, and flange and fan are protected fall into the edge within casket lower end suction opeing 50a, the 50b and match, the rectangular channel 111a that aims at 12,13 inboards, clamshell 10 two sides more upwards pushes, and then bottom plate 20 protects casket 50 with fan and clamshell 10 is combined into one easily.

During dismounting, then can be easily bottom plate 20 and fan be protected casket according to reversed sequence operation and take off cleaning respectively, and make flabellum 30a, 30b be exposed to outer wiping easily fully, so without any need for instrument, can be with free-hand with the said modules fast assembling-disassembling.
