Description

A kind of wall side is pushed up drawing range hood

Technical field

The utility model relates to lampblack absorber field, refers in particular to a kind of wall side and pushes up drawing range hood.

Background technology

Range hood is the requisite apparatus of modern kitchen, should be taken into account and be easy to effectively remove the grease and the dirt that accumulate in structural design, should accomplish that case surface is smooth as far as possible.Conventionally range hood need be fixed on the wall and use, so apart from outside key, hole slot, hook etc., also require it should have suitable device to be fixed on the wall, this device should be made by being difficult for mobile or on-deformable metal simultaneously.The air-breathing mode of lampblack absorber can be divided top suction type and side-suction type, but due to domestic culinary art custom, while cooking, can produce a large amount of oil smoke, in order to discharge as far as possible more oil smoke under the effect at equal-wattage blower fan, and consider the smooth degree of the clean and casing of kitchen ventilator of greasy dirt simultaneously, the inventor makes further research this, develops a kind of wall side and pushes up drawing range hood, and this case produces thus.

Utility model content

To achieve these goals, the technical solution of the utility model is as follows:

A kind of wall side is pushed up drawing range hood, comprise cavity A, cavity B, described cavity A and cavity B are L-type structure and internal communication, and cavity A forms a semi-enclosed structure towards basal plane A and the cavity B of gas-cooker towards the basal plane B of gas-cooker, angle a≤30 ° that basal plane A forms with respect to the upper surface of cavity A, angle b≤30 ° that basal plane B forms by wall rear surface with respect to cavity B, and angle c≤150 ° between basal plane A and basal plane B, described basal plane A and basal plane B are all invaginating stretching groove structure, on basal plane A and basal plane B, all offer ventilating opening; Between described basal plane A and basal plane B, also excessively connect by basal plane C, on described basal plane C, also offer ventilating opening.

Further, described basal plane A or basal plane B can be plane, can be also smooth curved surface, or the curved surface being made up of some planes.

Further, described basal plane C can be smooth curved surface, can be also plane, or the curved surface being made up of some planes.

Further, the bottom surface of described cavity B offers outage, under outage, oil trap is installed.

Further, on described A cavity or cavity B, offer some illuminating lamps.

Further, in the groove of described basal plane B, be also provided with cover plate, between described cover plate and groove wall, leave space.

Adopt after such scheme, the utility model compared with prior art, has the following advantages:

Under same power of fan, absorb by point cavity type, improve the clean absorption rate of oil smoke.

Fig. 2 is the side view of cavity A and cavity B.

Label declaration

Cavity A1, cavity B2, basal plane A3, basal plane B4, basal plane C5,

Ventilating opening 6, illuminating lamp 8, oil trap 9, cover plate 10, casing 11.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

As shown in the figure, a kind of wall side that the utility model discloses is pushed up drawing range hood, comprise the casing 11 that blower fan is housed, the cavity B2 that is positioned at the cavity A1 of blower fan below and arranges by wall, cavity A1 and cavity B2 form L-type structure and internal communication, and cavity A1 forms a semi-enclosed structure towards basal plane A3 and the cavity B2 of gas-cooker towards the basal plane of gas-cooker

Angle a≤30 ° that basal plane A3 forms with respect to the upper surface of cavity A1, angle b≤30 ° that basal plane B4 forms by wall rear surface with respect to cavity 2B, and angle c≤150 ° between basal plane A3 and basal plane B4, on basal plane A3 and basal plane B4, all offer ventilating opening 6, the bottom surface of cavity B2 offers outage, and a dismountable oil trap 9 is also installed under outage; On the correct position of lampblack absorber cavity, some illuminating lamps 8 and switch (switch omits in view) are installed, position is offered according to actual conditions.

Cavity A1 mean level arranges (be horizontally disposed with the upper surface of cavity A1 and be as the criterion) herein above gas-cooker, its basal plane A3 towards gas-cooker can be plane, also can be smooth curved surface (or the curved surface being formed by some planes), on basal plane A3, offer ventilating opening 6, in the present embodiment, basal plane A3 is invaginating stretching structure, can directly form a groove by punching press, easy to process and welding vestige.Compare planar structure, invaginating stretching structure is absorbing in the efficiency of greasy dirt highlyer, and the basal plane A3 caving in more easily forms negative pressure region, once and greasy dirt has entered in the basal plane A3 of depression, be just not easy along basal plane A3 to external diffusion.

Cavity B2 is that lampblack absorber cavity is by wall part, it is positioned at the below of basal plane A3 relatively towards the basal plane B4 of gas-cooker, basal plane B4 can be cambered surface, also be can plane, or be similarly invaginating stretching structure, can be more stepped composite surface, in the present embodiment, between basal plane A3 and basal plane B4, excessively connect by basal plane C5, on described basal plane C5, also can offer ventilating opening 6.

When basal plane B4 is invaginating stretching groove structure, in groove, be also provided with cover plate 10, between described cover plate 10 and groove wall, leave space, so not only convenient cleaning, also can prevent that foreign matter from calling in cavity B2, and outward appearance is more clean and tidy, cover plate 10 can be selected transparent glass, also can select opaque other materials.

The air-flow that the heat producing during due to culinary art causes, and the difference of the proportion of oil smoke own, the oil smoke diffusion producing has dividing of speed speed, from lower along basal plane B4 and the upper oil smoke being leaked can be sucked by basal plane A3 or basal plane C5, compared with utilizing the lampblack absorber of traditional cavity, smoke absorption effect is also higher: in the indoor cooking fume exhausting test experience of process, with the blower fan of equal-wattage, under identical indoor conditions, the oil smoke that identical oil mass is produced carries out suction, each time period of accumulative total gathers indoor oil smoke concentration value, and measured experimental result shows:

Adopting basal plane A3 is invaginating stretching structure groove, and basal plane B4 is planar structure, and oil smoke clean absorption rate is compared existing model, has improved 2-4%;

Adopting basal plane A3 is invaginating stretching structure groove, and basal plane B4 is also invaginating stretching structure groove, and oil smoke clean absorption rate is compared existing model, has improved 4-7%;

Adopting basal plane A3 is invaginating stretching structure groove, and basal plane B4 is also in the situation of invaginating stretching structure groove, then offers ventilating opening 6 at basal plane C5, and oil smoke clean absorption rate is compared existing model, has improved 5-10%.

Above are only specific embodiment of the utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
