Problems solved by technology

Although the technical means of instantly removing oily fumes can greatly improve the efficiency of oily fume exhaust, in practice, it is still impossible to quickly suck the oily fumes into the range hood A, causing the oily fumes to escape and spread to other directions
[0008] The main reason for the above problems is that the above technical solution belongs to the fan to push the fume air out through the pipe. Due to the limitation of the pipe, the fan-type range hood cannot completely discharge the inhaled air, resulting in a reduction in work efficiency.
In addition, the huge noise caused by the high-power fan and the pollution of the fan by the oil fume still have not solved the shortcomings of the traditional range hood.

Embodiment 1

[0053] Fig. 3 shows a schematic diagram of the composition of a specific embodiment of the present invention. It is a split structure fume exhaust device. It includes a blower fan 1 installed outdoors for sucking indoor air, and a variable-diameter exhaust pipe 2 with different diameters at both ends. The variable-diameter exhaust pipe 2 is composed of two sections of pipes with different diameters. The larger end extends out of the room and is connected to the air inlet of the blower fan 1, and the smaller end is connected to the air outlet of the suction part installed indoors for forming local air negative pressure. In this embodiment, the air intake part is composed of a plurality of air intake pipes 3 . One end of each suction pipe 3 is an air outlet, and is jointly connected with the small end of the reduced-diameter exhaust pipe 2 . Each air suction pipe 3 can send the indoor air sucked by the other end into the variable diameter exhaust pipe 2 .

Embodiment 2

[0057] Fig. 5 is a structural principle diagram of a second specific embodiment of the present invention. In the figure, the suction part is two pipe grooves 4, and the air outlets provided on the two pipe grooves 4 are connected with the reduced-diameter smoke exhaust pipe 2 in the same way as the first embodiment above. A plurality of suction holes 41 are also provided on the two pipe grooves 4 . Proper arrangement of the plurality of suction holes 41 can form a local air negative pressure zone around the pipe slot 4 when the fan 1 is working.

[0058] The shape of the pipe groove 4 can be various, it can be linear, it can also be zigzag, and it can also be annular.

[0059] Fig. 6 shows the oil fume exhaust device that adopts this embodiment together with the stove and the cabinet. In the figure, an annular pipe groove 4 is arranged on the edge of the bottom panel of the cabinet a above the stove b, and two pipe grooves 4 are arranged transversely in the middle. Between ...

Embodiment 3

[0062] Fig. 7 shows another structure of the suction part in the third specific embodiment of the present invention. In the figure, the suction part is a fume exhaust plate 5, which is a plate body, and is provided with a recessed part 51 and an air outlet 52 for sucking indoor air on the surface, and one end of the air outlet 52 is connected to the recessed part. 51 is communicated, and the other end is connected with variable-diameter exhaust pipe 2. The shape of the recessed portion 51 is a rectangle, and any other shape can also be adopted. When the fan is started, the air in the recessed part 51 is sucked out through the variable-diameter exhaust pipe 2, forming a negative air pressure in the recessed part 51. A negative pressure area is formed inside, and the external air flows to this area to form a supplementary pressure airflow, and the oil fume generated in this area cannot spread around, and is sucked by the recessed part 51 and then discharged to the outside.

Abstract

The utility model relates to a separate-structured smoke exhaust device and comprises a blower which is arranged outdoor and can be used for sucking indoor air; the device also comprises a variable diameter air exhaust pipe; the variable diameter air exhaust pipe consists of at least two sections of pipelines with different diameters; one end with larger diameter is connected with an air inlet of the blower and the other end with smaller diameter is connected with an air outlet of an aspiration part which is arranged indoor and is used for formation of a local air negative pressure area. The invention arranges the blower outdoor so that the kitchen has no noise when in smoke exhaustion, meanwhile, when in work, the indoor air negative pressure area formed by the smoke exhaust device can keep smoke around a hearth and a cupboard from spreading to other areas; therefore, the device completely overcomes various shortcomings of the prior smoke exhaust device and eliminates floating smoke generated in the process of cooking; the device has the capacity of exhausting smoke rapidly, voicelessly and profoundly, with easy installation, and cannot occupy space of the kitchen.

Description

technical field [0001] The present invention relates to a split-structure oil fume exhaust device, in particular to a device in which the blower and oil suction parts are separately arranged, and the negative pressure area formed by a plurality of negative pressure points in the room effectively captures the oil fume in the air, so that the oil fume cannot A split-structure oil fume exhaust device that spreads to the surroundings and quickly exhausts the outdoors without noise. Background technique [0002] For many years, range hoods of various structures have been widely used in people's daily life as a kind of kitchen equipment. To a certain extent, the environmental pollution caused by oil fume in the kitchen has been removed for people. However, there are still some technical defects in the existing range hoods, among which the relatively large working noise is an important defect that cannot be eliminated. [0003] Existing range hoods of any style, no matter it adopt...
