Description

Separation net on range hood

Technical Field

The utility model relates to a separation net, it is concrete relates to a separation net group on smoke ventilator.

Background

The smoke exhaust ventilator is a kitchen utensil, inhale the oil smoke through the motor fan, then separate the oil smoke, discharge relatively clean air, because impurity is more in the inspiratory oil smoke, carry out the oil smoke separation through the separation net, pass through the spacer with the oil smoke of high temperature, form the backward flow through the striking, because spacer surface temperature is low, the oil smoke of backward flow can condense into liquid on the spacer, then discharge, other gas of surplus is through other accessory filtration processes of lampblack absorber, therefore, the route of backward flow has been decided to the structure of spacer, also direct influence oil smoke separation efficiency.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned problem that prior art exists, the utility model aims to provide a separation net on smoke ventilator adopts integrated configuration, adopts many arcs face spacer structure, improves oil smoke separation efficiency, has improved product performance.

In order to realize the purpose of the utility model, the utility model adopts the following technical scheme:

the utility model provides a separation net on smoke ventilator, be upper and lower integrated configuration, including upper strata separation plate and lower floor' S separation plate, every layer of separation plate is arranged by independent release sheet respectively and constitutes, the release sheet is symmetrical structure, be "T" type, the side is convex groove structure, the intermediate position is equipped with the spacing hole, the release sheet both sides include cambered surface I on the inner wall and cambered surface II on the outer wall, be cambered surface III between the cambered surface II of release sheet both sides, the release sheet is equipped with spacing hole position outer wall and is cambered surface IV, release sheet relative arrangement on upper strata separation plate and the lower floor separation plate and cambered surface I on the upper strata separation plate and the lower floor separation plate inlay and form "S" type separation chamber, cambered surface IV on the lower floor separation plate forms the oil smoke entry with the combination of cambered surface II on the upper strata separation plate, cambered surface IV on the upper strata separation plate forms the oil smoke export with the combination of cambered.

Preferably, the distance between the arc surface port of the separation sheet on the upper separation plate and the arc surface port of the separation sheet on the lower separation plate is not less than 0, so that the upper separation plate and the lower separation plate are combined to prevent scraping, and the service life of a product is prolonged.

Preferably, the distance between the oil smoke inlet and the oil smoke outlet is a structure with a thin middle part and thick two ends, and the gradually-changed structure enables the oil smoke to form backflow in the outlet, the inlet and the separation cavity, and is fully cooled and separated.

Preferably, the separator sheet upper arcuate surface iii is recessed inwardly of the separator sheet. On one hand, the surface area of the separation sheet is increased, so that the oil smoke is fully condensed, and on the other hand, the oil smoke is divided by the sunken arc surface and is fully separated.

Compared with the prior art, the beneficial effects of the utility model are that: the surface of the separating sheet adopts an arc-shaped structure, so that the surface area is increased, the oil fume separation efficiency is improved, the oil fume is fully cooled and separated by the separating cavity formed by the upper and lower combined structures, the oil fume separation efficiency of the range hood is further improved, the oil fume has better flow guide effects at the inlet and outlet positions by adopting the gradual flow passage, and the oil fume separation efficiency is further improved.

Fig. 1 is a schematic structural diagram of a preferred embodiment of a separation net on a range hood provided by the present invention.

Detailed Description

The invention will be described more fully hereinafter with reference to the accompanying drawings and preferred embodiments.

Fig. 1 is a schematic view of a preferred embodiment of a separation net on a range hood provided by the present invention. As shown in figure 1, the separating net on the range hood is of an up-and-down combined structure and comprises an upper separating plate 1 and a lower separating plate 2, each separating plate is respectively formed by arranging independent separating sheets 3, the separating sheets 3 are of a symmetrical structure and are in a T shape, the side edges are of arc-shaped groove structures, a limiting hole 301 is formed in the middle position, two sides of each separating sheet 3 comprise an arc surface I302 on the inner wall and an arc surface II 303 on the outer wall, an arc surface III 304 is formed between the arc surfaces II 303 on the two sides of each separating sheet 3, the outer wall of each separating sheet 3 at the position of the limiting hole 301 is an arc surface IV 305, the separating sheets 3 on the upper separating plate 1 and the lower separating plate 2 are oppositely arranged, the arc surface I302 on the upper separating plate 1 and the arc surface I302 on the lower separating plate 2 are embedded to form an S-shaped separating cavity 4, the arc surface IV 305 on the lower separating plate 2 and the arc surface II 303, the arc IV 305 on the upper layer separating plate 1 and the arc II 303 on the lower layer separating plate 2 are combined to form a lampblack outlet 307.

Particularly, the distance between the circular arc surface port of the separation sheet 3 on the upper separation plate 1 and the circular arc surface port of the separation sheet 3 on the lower separation plate 2 is not less than 0, the distance between the oil smoke inlet 306 and the oil smoke outlet 307 is of a structure with a thin middle part and two thick ends, and the upper arc surface III 304 of the separation sheet 3 is sunken towards the inside of the separation sheet 3.

In the using process, one part of oil smoke enters from an oil smoke inlet 306, the other part of the oil smoke collides with an arc surface III 304 on an upper layer separation plate 2, the oil smoke colliding with the arc surface III 304 finally enters the oil smoke inlet 306 through flow division, the oil smoke entering the oil smoke inlet 306 enters an S-shaped separation cavity 4, the oil smoke forms overturning in the separation cavity 4 due to the arc surface I302 and a gradual flow passage, the temperature difference between hot oil smoke and the inner wall of the separation plate enables the oil smoke to be fully condensed, impurities in the oil smoke are condensed, other gases are discharged from an oil smoke outlet 307, and the oil smoke separation effect is formed.

Finally, it must be said here that: the above embodiments are only used for further detailed description of the technical solution of the present invention, and should not be understood as limiting the scope of the present invention, and the non-essential modifications and adjustments made by those skilled in the art according to the above description of the present invention are within the scope of the present invention.
