Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As depicted in figs. 1 and 2, with direction shown in Fig. 1 arrow for dextrad is described, the range hood in the present embodiment comprises blower hood 1, exhaust fume collecting hood 2, filter screen 3, cowling panel 4 and blower fan 5 and the assembly such as foam maker 6 and lubricating cup 7.Wherein, blower fan 5 is arranged in blower hood 1, filter screen 3 is arranged on the bottom of blower hood 1 and is positioned at the central authorities of exhaust fume collecting hood 2, cowling panel 4 to be arranged on exhaust fume collecting hood 2 and to be positioned at the below of filter screen 3, the air intake region of foam maker 6 between cowling panel 4 and filter screen 3, lubricating cup 7 is arranged on the below on rear side of cowling panel 4.
In the present embodiment, the incline structure that cowling panel 4 is high in centre, the left and right sides is low, foam maker 6 has two, and is located at the left and right sides at cowling panel 4 back side respectively.Each foam maker 6 comprises foam liquid container 61, motor 62, rotary blade type foaming ring 63 and nozzle 64.Wherein, foam liquid container 61 and motor 62 are fixed on the back side of cowling panel 4, the driving shaft level of motor 62 and arranging inwardly, rotary blade type foaming ring 63 is arranged on the driving shaft of motor 62, nozzle 64 be located at the outside of rotary blade type foaming ring 63 and gas outlet inwardly, and rotary blade type foaming ring 63 can dip the foam liquid in foam liquid container 61 and turn to just to the position of nozzle 64 gas outlet under the driving of motor 62.Particularly, rotary blade type foaming ring 63 comprises three foaming rings be centrosymmetric, like this, along with the rotation of rotary blade type foaming ring 63, three foaming rings can stretch into foam liquid container 61 in turn and dip foam liquid, correspondingly, the foaming ring dipping foam liquid in turn just to the gas outlet of nozzle 64, thus can blow out bubble in consistent ground.In addition, in order to form acceleration air-flow, nozzle 64 is funnel-form, and the larger one end of bore is inlet end, one end that bore is less is outlet side, and the inlet end of nozzle 64 outwardly, inwardly, the suction airstream that blower fan 5 produces, by forming acceleration air-flow after nozzle 64, is conducive to formation of foam to inlet end.
As shown in Figure 3, in order to collect the oil droplet falling into cowling panel 4 smoothly, being formed with the flange 41 upwards turned down in the surrounding of cowling panel 4, in the side of cowling panel 4 also near having oil strain hole 42 with side flanging place, in the below in oil strain hole 42, lubricating cup 7 being installed.Certainly, also can form oil guide groove in the surrounding of cowling panel, in the gathering sill of rear side, have oil strain hole, in the below in oil strain hole, lubricating cup is installed.
The foam maker of the present embodiment preferably adopts foam soap generator, at foam liquid container 61 built with liquid soap, during range hood work, blower fan 5 startup produces suction airstream and drives air-flow below exhaust fume collecting hood 2 to walk around cowling panel 4 flows toward top, nozzle 64 is utilized to collect air-flow to accelerate air-flow, motor 62 rotating drive rotary blade type foaming ring 63 dips in upper liquid soap from foam liquid container 61 simultaneously, when rotary blade type foaming ring 63 is by nozzle 64 position, gas outlet time, nozzle 64 air-flow blows afloat the soap around foaming ring, form soap bubble, a large amount of soap bubble can be formed at short notice by control motor speed and nozzle form.Soap bubble in air motion process because surface area is large, and liquid soap easily dissolves the impurity such as oil smoke and dust, can by flue gas Impurity Absorption to liquid soap, when soap bubble is by top filter screen 3 time, soap bubble breaks, liquid poly-doped impurity, grease instillation cowling panel 4, and flow into the lubricating cup 7 on rear side of cowling panel along cowling panel 4.
In addition, through experiment, after adopting the foam maker in the present embodiment, under the prerequisite not reducing oil strain effect, can suitably increase filter screen by area, to reduce resistance.
The foregoing is only the preferred embodiment of the present invention; should be understood that; for those of ordinary skills; do not departing under principle prerequisite of the present invention; multiple remodeling or improvement can be carried out to the present invention; such as can arrange multiple foam maker around air intake region, these are all regarded as within protection scope of the present invention.
