Description

Improved range hood

Technical field:

The utility model relates to a kind of cooking apparatus, relates in particular to a kind of range hood that is used to get rid of oil smoke in the kitchen.

Background technology:

The use of lampblack absorber has at present spreaded all over huge numbers of families, in order to increase the suction space of oil smoke, gets rid of oil smoke better, and range hood generally all is equipped with exhaust fume collecting hood.And in the prior art, there are many deficiencies in exhaust fume collecting hood with being connected of housing and front shroud: two kinds of connected modes are arranged usually, and a kind of is the front end that exhaust fume collecting hood is loaded on housing, and mode hinged by an end, other end clamping links to each other with housing.As the Chinese utility model patent CN2318540 of Granted publication on May 12nd, 1999, a kind of convenient vertical smoke exhaust ventilator that cleans is disclosed, this smoke exhaust ventilator is made up of casing (being housing), centrifugal blower and exhaust fume collecting hood, and the rear end face of exhaust fume collecting hood is provided with deflector; The lower hinge of exhaust fume collecting hood is on casing, and top connects as one by retaining mechanism and casing.Although this smoke exhaust ventilator can be opened and is convenient to clean owing to exhaust fume collecting hood, the syndeton of housing and exhaust fume collecting hood is comparatively complicated, the manufacturing cost height, and also it is big to occupy the space after the two combination.Another kind is the inside that exhaust fume collecting hood directly is arranged at housing, flange by centrifugal blower is fixed exhaust fume collecting hood, form the slit between the two side of exhaust fume collecting hood and housing in this scheme, thereby can bring two shortcomings: the one, the oil smoke that does not drain between housing and the exhaust fume collecting hood can pool oil droplet, drip the kitchen range top under the pollution from the slit of both sides; The 2nd, because the slit that forms between exhaust fume collecting hood and the housing is positioned at the downside of lampblack absorber, make troubles to scouring.

In order to overcome above-mentioned the deficiencies in the prior art, the applicant has proposed Chinese utility application 200320129834.X number, on December 22nd, 2004 by State Intellectual Property Office's Granted publication, notification number is CN2665568.Referring to Fig. 1, the range hood shell 1 of this patent disclosure and the both sides of exhaust fume collecting hood 3 are connected by the end wall of bending, thereby both sides oil dripping more not, also are convenient to cleaning.But anterior protecgulum 2, housing 1, exhaust fume collecting hood 3 threes have still adopted known connected mode, make troubles to scouring in the anterior slit that still forms leakage of oil.

The utility model content:

The technical problems to be solved in the utility model is the deficiency that overcomes above-mentioned prior art, and a kind of improved range hood is provided, its not only anterior slit that also can not form oil dripping, and the oil smoke that the does not drain pollution kitchen range top that can not drip, it is also comparatively convenient to clean; And make, assembling is all convenient, reduced production cost.

According to the improved range hood that the utility model provides, comprise a housing and be installed on the interior blower fan of described housing, driving blower fan motor rotating and electric control system; The front of described housing is equipped with front shroud, be provided with exhaust fume collecting hood in the described housing, the lower front face of described housing is provided with a connection strap, and the two ends of described connection strap extend to the two side of described housing, and described front shroud is connected by described connection strap with described exhaust fume collecting hood; Described connection strap and/or described front shroud are provided with press button.

The utility model also has following attached technical characterictic:

Described front shroud covers the whole front surface of described housing, and its both sides are mutually concordant with the two ends of described connection strap.

The upside of described connection strap is formed with groove, and downside also is formed with groove; The lower limb of the lower limb of described front shroud and described exhaust fume collecting hood front portion inserts respectively in the described groove, and closely cooperates with it.

Described connection strap comprises an antetheca and the oblique L type kink that extends internally from the upper end of described front wall inner surface, and from the inside vertically extending cross wall in the lower end of described front wall inner surface with from the downward longitudinal wall that extends of described cross wall; The termination of described oblique L type kink and described antetheca upper end forms the described groove that holds described front shroud lower limb, forms the described groove that holds described exhaust fume collecting hood lower limb between the termination of described longitudinal wall and described antetheca lower end.

Described front shroud is hollow double-shell structure, comprises outer wall and the inwall parallel with described outer wall, and the end wall and the skew wall that connect described outer wall and inwall, described inwall, end wall and skew wall form can with the termination of described groove fit.

The thickness of described oblique L type kink is greater than the thickness of described antetheca, and it is made of end walls, and an end wall is vertical with described front shroud, and another end wall is parallel with described front shroud.

The lower limb of described exhaust fume collecting hood front portion is bending upwards, thereby inserts in the described groove.

The thickness of described cross wall and longitudinal wall is all greater than the thickness of described antetheca.

Described control button is located on the described connection strap, and is electrically connected with described electric control system.

Described housing, front shroud and exhaust fume collecting hood are all by the metallic plate drawing; Described connection strap is by the aluminium section bar extrusion molding.

The improved range hood that provides according to the utility model, prior art has following advantage relatively: because the front lower ends of housing is provided with connection strap, the lower limb of front shroud and exhaust fume collecting hood is connected by connection strap, thereby the anterior structure that forms sealing, can not produce the slit of oil dripping, the oil smoke that between exhaust fume collecting hood and housing, the does not drain pollution kitchen range top that yet can not drip; And the exhaust fume collecting hood inner chamber forms jointless smooth surface, greatly facilitates scouring.In addition, set up connection strap after, make that the installation of front shroud and exhaust fume collecting hood is all convenient, reduced production cost.
