CN2243613Y - Hood without exhaust tube - Google Patents

Abstract

The utility model relates to a hood without an exhaust tube. The back half part of the bottom board of the hood is made into a filter screen structure that the filter screen is composed of two square metal screens clamping a sponge and the middle part of the filter screen is concave, and the front part of an air box is provided with a filtering box body whose top part is provided with an air exhaust hole and two activated carbon filtering sheets capable of being inserted to the air box. The utility model is characterized in that the hood without the exhaust tube is only added with a filter device on the structure of the original hood, and therefore, the utility model avoids the defects that the existing hood without the exhaust tube has complicated structure and high producing cost due to being newly designed and manufactured.

Description

Exempt from smoke exhaust with smoke discharging pipe

Exempt from the smoke exhaust with smoke discharging pipe, it relates to household electrical appliance adjusting device category.

The flue gas that existing smoke exhaust is discharged generally is directly to enter in the atmosphere by smoke discharging pipe, thereby causes pollution and influence ecological environment to atmosphere and environment.Manufacturer designs smoke exhaust without smoke discharging pipe by filtration system filters oil smoke own in recent years, but it is different with the shape and structure of traditional smoke exhaust.Exist the process structure complexity, must be from newly manufacturing and designing, thereby production cost is high and make complicated defective.

The purpose of this utility model is to propose a kind of exempting to be improved on original structure with smoke discharging pipe, increases filter, overcomes the existing high weak point of complex manufacturing cost without the existence of smoke discharging pipe smoke exhaust.

The utility model is realized in the following way, in position, smoke exhaust inlet scoop, on half base plate position, back, adorn respectively one square by wire netting clamping sponge layer, middle for being recessed into circular-arc filter screen, along sump oil circuit and sump oil mouth are arranged on the periphery, fixing clip with rotation is arranged on four jiaos of bases, button hangs over range fan shell and divides below the base plate 2.In bellows and middle part, outer casing top surface both sides, be shaped on a triangle casing, one platoon leader's strip exhaust opening is arranged on the top, and the exhaust opening back has two can insert active carbon filtration sheet strip hole, and filter is installed in the holddown groove on strip hole and the triangle tank floor.

The advantage that this utility model has is, increases filter on original lampblack exhauster structure, and it is indoor that the gas that becomes cleaning after the filtration can directly be entered, and avoided contaminated environment, and its simple in structure causing conveniently, and reduced production cost.

Accompanying drawing 3, the utility model B is to partial enlarged drawing

In conjunction with the accompanying drawings a kind of exempting from of the utility model is described further with the smoke exhaust of smoke discharging pipe below by embodiment, the smoke exhaust base plate is by the first half base plate 2 and latter half of composition of band illuminating lamp, divide base plate to be shaped on chimb, another side is shaped on fixture block, latter half of is the smoke evacuation part, a square is housed by constituting for recessed circular-arc filter screen 3 in the middle of the wire netting clamping spongy layer respectively by two below inlet scoop 15.Be shaped on the sump oil mouth 16 that is communicated to oil-collecting ring 6 in the middle of being shaped on sump oil circuit 13 back on 3 four edges of filter screen, four bights, base are shaped on fixing with rotatable clip 7, its front is stuck in the fixture block interior 17 of branch base plate 2, another side is stuck in the shell 1 with rotation clip 7, triangle casing 5 of system in the middle of bellows 18 leading flank middle parts and outer casing top surface, its back communicates with bellows inside, be shaped on the vertical strip exhaust smoke hole 9 of a row at the triangle box top, be shaped on two strip holes 8 and 10 that can insert active carbon filtration sheet 4 behind the hole.Under the hole at the bottom of the case on corresponding position be shaped on 14, two active carbon filtration sheets 4 of holddown groove, pass strip hole 8 and 10 and be inserted in the holddown groove 14 and fixedly form.

Claims (1)

1. A kind of a kind of smoke exhaust of exempting from smoke discharging pipe, it comprises shell, casing, bellows, fan composition, it is characterized in that, adorn respectively on half base plate position behind the position, inlet scoop (15) one square by being recessed circular-arc filter screen (3) in the middle of the wire netting clamping sponge layer, along sump oil circuit (13) and sump oil mouth (16) are arranged on the periphery, there is fixing clip (7) button to hang over below range fan shell and the branch base plate (2) on four jiaos of bases with rotation; In bellows (18) and middle part, shell (1) end face both sides, be shaped on a triangle casing (5), have platoon leader's strip exhaust opening (9) exhaust opening back to have two can insert active carbon filtration sheet (4) strip hole (8) and (10) on the top, filter (4) is installed in the holddown groove (16) of strip hole (8), (10) and triangle tank floor.
