Figure 11 is the stereogram when oblique upper is looked grease filter, and Figure 12 is the amplification sectional view of this major part.

Grease filter 9, the sheet metal that constitutes by outstanding aluminium sheet such as corrosion resistance or corrosion resistant plate etc. when overlooking, forms the rectangular shape of size of the aperture area of the contact mouth 6 with the top board 1a that is equivalent to be opened on housing section 1.

As shown in figure 11, this grease filter 9, the mode that sheet metal is divided with clathrate roughly when overlooking is provided with the slit 33 of multiple row on a direction with several millimeters spacing in each division portion 32.

And, the tongue piece portion 34 of the planar sections that will divide mutually with the slit 33 of each division portion 32, towards a side surface direction of sheet metal, even, cut to a direction bending, thereby do not stayed planar section and blow vent 35 (with reference to Figure 12) that opening tilts to a direction.

And as shown in figure 11, grease filter 9 has at each edge, four limits with the reinforcement edge portion 36 of right-angle bending.Thus, the grease filter 9 that is made of sheet metal forms tray shape, thereby can not twist or as the distortion of fluctuating shape deflection etc.

According to the grease filter 9 of the present embodiment of formation like this, waste gas etc. by the time, direct exhaust is with straight-line pass blow vent 35, but crawls in the tongue piece portion 34 of bending.Thus, can be with fewer ventilation impedance, obtain to be contained in the high capturing efficiency of the lubricant component of waste gas.

In addition, the grease filter 9 of present embodiment is to form blow vent 35 by having cut at sheet metal, therefore compares with the known grease filter that is made of spun gold net or steel wire, and cleaning property is good.Therefore can, continuation steady in a long-term is as the function of the capturing efficiency of desired ventilation impedance of filter and lubricant component etc.

Figure 13 is the stereogram when oblique upper is looked smoke exhaust ventilator.

As shown in figure 13, air-supply arrangement 2 has exhaust apparatus 4 that is connected with blast pipe 36 and the exhaust pipe shield 7 that can stretch up and down, and this exhaust pipe shield 7 is used for hidden this exhaust apparatus 4 and blast pipe 36.

Figure 14 is the vertical profile front view that amplifies an expression smoke exhaust ventilator part, and Figure 15 is this vertical profile side view.

As shown in figure 14, exhaust apparatus 4, the position sets on the fan guard 38 of the connecting cylinder 37 that is connected with blast pipe 36 on circumference, with its coaxially built-in shaft be supported on the ventilating fan 40 of ventilating fan motor.

Figure 16 is the exploded perspective view of expression ventilating fan, and Figure 17 is the vertical view that the blade of this ventilating fan of expression constitutes plate.(a) of Figure 18 is to the assembling sequence of (j) expression ventilating fan.

As shown in figure 16, ventilating fan 40 by cylinder 40a, be used for respectively fixing a lateral margin body 40b, and another lateral margin body 40c and constituting of the both sides circumferential rim of this cylinder 40a by crimping.

Cylinder 40a constitutes plate 41 by adjacent setting on circumference and the blade that connects necessary amount to constitute.

As shown in figure 17, blade constitutes plate 41, has both sides board 41b towards the desired length dimension of length of blade L direction with the wide W direction of the blade of regulation curvature bending both ends respectively by narrower part 41a.And this blade constitutes plate 41, has vertical plate part 41c side by side respectively and insert sheet 41d on its length of blade L direction from the middle part of both sides board 41b.

In addition, as shown in figure 17, blade constitutes plate 41, in the boundary portion that erects of vertical plate part 41c or near this boundary portion patchhole 42 is set.This patchhole 42 forms the slotted hole shape, the insertion sheet 41d of adjacent setting can be inserted fastening and constitute plate 41 each other at the blade of adjacent setting.

As shown in figure 16, a lateral margin body 40b forms the annular shape that has along the size of the side circumferential rim of cylinder 40a by bending machining etc.And, as (d) of Figure 18 and (e), this lateral margin body 40b has junction surface 44, and this junction surface 44 is used for along the side circumferential rim side of cylinder 40a crooked erecting and after 43 groups of coverings of described later upright end of forming, fixing by crimping respectively towards inner opening.

Another lateral margin body 40c forms the circular plate shape that has along the size of the side circumferential rim of cylinder 40a by stamping-out processing etc.

And, as shown in figure 16, this another lateral margin body 40c, except that have with a lateral margin body 40b equally towards the periphery ring plate edge portion 45 at the junction surface 44 of inner opening, also have from the radiation armed lever 46 of this periphery ring plate edge portion 45 by the four directions and connect the central support 47 that is provided with.And, have hub portion 48 at this central support 47, so that being installed in the rotating driveshaft 39a of ventilating fan motor 39, overcoat goes up (with reference to Figure 14).

Then, the assemble method of the relevant ventilating fan 40a of simple declaration.

At first, assembling forms cylinder 40a.Shown in Figure 18 (a), this cylinder 40a, it is adjacent to make the blade of adjacent setting constitute plate 41 with needed interval, and the 41b of side plate portion reaches opposite side board 41b to each other to each other, and the insertion sheet 41d that bending is erected inserts fastening in patchhole 42.

Shown in Figure 18 (b) and Figure 18 (c), vertical plate part 41c bending erected and make it to be fixed in and insert sheet 41d from outside fastening, thereby form 42 groups at upright end having both connecting portion 43a, and constitute plate 41 with the blade that oblong-shaped connects necessary amount, thereafter, be rolled into cylindricly, form cylinder 40a and can assemble.

Shown in Figure 18 (d) and Figure 18 (e), so after the assembling cylinder 40a, with with 42 groups of modes of reeling to the inside of upright end of the side circumferential rim of cylinder 40a, with the junction surface 44 of a lateral margin body 40b or with 42 groups at the upright end of the opposite side circumferential rim of the cylinder 40a modes of volume to the inside, connect the crooked junction surface 44 of fixing another lateral margin body 40c by crimping respectively, thereby assembling constitutes ventilating fan 40.

Shown in Figure 18 (g), the ventilating fan 40 of the present embodiment that constitutes according to assembling like this, blade constitutes plate 41 mutual connecting portion 43a and has hierarchic structure 49, this hierarchic structure 49 forms with 43 at the upright end that the vertical plate part 41c that is positioned at its rear constitutes by inserting sheet 41d, therefore be involved in this hierarchic structure 49 by crimping and fix a lateral margin body 40b and another lateral margin body 40c (with reference to Figure 18 (f)), become the state that is capped that does not expose at a lateral margin body 40b and another lateral margin body 40c.Thus, the blade bonding strength that constitutes the mutual connecting portion 43a of plate 41 doubles to increase.

And as Figure 18 (f) and (g), a lateral margin body 40b and another lateral margin body 40c by crimping during with fluctuating shape fixed step structure 49 are absorbed in and form the portion that is absorbed in 50 with rib function.Thus, prevent relative position skew, simultaneously, prevent the lateral margin body 40b that causes through long-term use and the durability variation of another lateral margin body 40c the lateral margin body 40b of cylinder 40a and another lateral margin body 40c.

And, blade is set on upright end 43 constitutes the mutual connecting portion 43a of plate 41, and its upright end 43 is fixed on a lateral margin body 40b and another lateral margin body 40c with crimping.Therefore, the blade that can play stably for a long time constitutes the mutual bonding strength of plate 41, can not keep the air-supply function of permanent regulation because of the lax angle that make blade constitute plate 41 of connecting portion 42a changes.In addition, connecting portion 43a does not reveal the outside (outside), hinders cleaning as thrust and worries such as injured take place thereby can separate its connecting portion 43a that disappears.

And then, when the hierarchic structure of connecting portion 43a 49 is fixed with crimping, the portion that is absorbed in 50 with the relativity shift of cylinder 40a that prevents is formed on a lateral margin body 40b and another lateral margin body 40c.Thus, the long-term use can not taken place yet, and cylinder 40a can expect reliability to another lateral margin body 40c (reception and registration power plate), another lateral margin body 40c with respect to the position skew of cylinder 40a, significantly improving on the aspect such as durability.On it, be absorbed in portion 50 and have the rib function, so long-term the use do not worry that a lateral margin body 40b or another lateral margin body 40c can be out of shape yet.

And, in the present embodiment, as shown in figure 14, install and be contained on the ventilating fan motor 39 and the fan guard 38 of built-in ventilating fan 40, the front with effluent jet pipe 51 attracts mouthfuls 52, in addition, also has the mouth of attraction 53 in the rear side that ventilating fan motor 39 is installed with coaxial shape, thus, the noise of the wind noise that takes place in the time of can stoping by running etc. reduces its noise level.

And, in the present embodiment, make to be contained in the lubricant component that uses in the waste gas that adheres to the inner peripheral surface that accumulates in fan guard 39 etc. etc. because of long-term, as Figure 14 and shown in Figure 15,, then make it be dropped in grease filter 9 in case flow out to outside the fan guard 39.

Promptly, the lubricant component that is contained in waste gas etc. is, waste gas is in passing through the process of grease filter 9, the grease that lubricated grease filter 9 is removed from waste gas, but the absorption rate of recovery by the lubricant component of grease filter 9, be unlikely to 100%, enter in the fan guard 39 and pass grease filter 9.Therefore, because of using for a long time, lubricant component finally accumulates in the circumference bottom of fan guard 39 gradually attached to the inner peripheral surface of fan guard 39.

If with this oil accumulate put no matter, can be mixed by ventilating fan 36, thus the lubricant component that accumulates can be dispersed outside fan guard 39, or the lubricant component that accumulates is solidified, thereby can cause that the air draft ability that the rotation by ventilating fan 36 brings reduces.

So, present embodiment, as Figure 14 and shown in Figure 15, circumference bottom at fan guard 39 has a plurality of outages 54, and has grease inclined-plane 55 at the top board 1a of housing section 1, liquid grease inclined-plane arrives the grease filter 9 of the contact mouth 6 of being located at housing section 1 from the position of just descending of outage 54, thereby drop onto grease inclined-plane 55 from the outage 54 of fan guard 39, simultaneously, drop onto grease filter 9 by grease inclined-plane 55, finally be recovered to the oily recoverer 16 of central cover 14 from the

cowling panel

11,12 that is provided in grease filter 9 downsides respectively.
