Description
Technical field
The present invention relates to a kind of cooking-fume exhauster blower volute, especially a kind of cooking-fume exhauster blower volute that is provided with the oil smoke dashpot.
Background technique
Range hood is the electrical equipment commonly used of kitchen pump drainage oil smoke; European-style range hood adopts in the spiral case and installs driven by motor impeller pump drainage oil smoke additional; Existing European-style range hood has been popularized double-faced ventilated structure; Like the patent No. is the utility model patent " two air-inlet range hood " of ZL200420082377.8 and the utility model patent " blower volute structure of the European range hood that a kind of ability is double-faced ventilated " that the patent No. is CN200620103331.9; And the patent No. is that the Chinese utility model patent " blower volute structure of European range hood that can be double-faced ventilated " of CN200620103332.3 all provides this technological scheme; But this technological scheme is because the ring-type spiral case is that the right angle is connected with front and rear cover plate, causes the oil smoke air-flow can't water conservancy diversion, generation disorder and noise.The back patent No. is the patent of invention " a kind of double-faced ventilated cooking-fume exhauster blower volute " of CN200710069947.8; Through the intake grill that a curved surface connecting plate that protrudes downwards drains into forward and backward cover plate is set between forward and backward cover plate; But in fact; This volute of blower can't cushion the oil smoke air-flow; The high heavy-duty motor of energy consumption need to be installed to be used, and the noise of heavy-duty motor own is big, and do not reach the pump drainage oil smoke effect of this patent scheme narration when using low-power machine at all.
Summary of the invention
In view of this, the technical problem that the present invention solved is to provide a kind of cooking-fume exhauster blower volute that is provided with the oil smoke dashpot.
The technological scheme of a kind of cooking-fume exhauster blower volute of the present invention is: comprise protecgulum, bonnet, ring-type spiral case, flow distribution plate and oil smoke dashpot; The two ends of this ring-type spiral case connect protecgulum and bonnet; This protecgulum and bonnet are respectively equipped with circular preceding intake grill and rear air inlet; The center of circle vertical symmetry of intake grill and rear air inlet before being somebody's turn to do, the two ends of this flow distribution plate are respectively equipped with bending edge, and this bending edge is connected fixing respectively with the lower end of protecgulum and bonnet; This flow distribution plate bottom curved surface indent forms an arcuation oil smoke dashpot, and this oil smoke dashpot extends to the both sides of flow distribution plate.
Said flow distribution plate is an individual components non-and protecgulum and bonnet integrative-structure, and the flow distribution plate lower end is provided with oil collecting hole.
The curved surface cross section of said flow distribution plate is divided into five sections, the arc section CD of middle indent, and the front side straightway AB of protecgulum lower end and front side curved section BC, the rear side straightway EF of bonnet lower end and rear side curved section DE connect for smooth transition between the adjacent segment.
Described front side straightway AB be 32 ° perpendicular to the horizontal plane angle of protecgulum, described rear side straightway EF is 52 ° with horizontal plane angle perpendicular to bonnet.
Described volute of blower edge contour is straight line AB, curve B C, circular arc C D, curve D E and the straight line EF of rounding off are formed by connecting successively; Described straight line AB and curve B C are tangential on a B; Curve B C and circular arc C D are cut in a C outward; Circular arc C D and curve D E are cut in a D outward, and curve D E and straight line EF are tangential on an E.
Be covered with electric machine support after described, this electric machine support by an inner annular plate and three radially connecting plate constitute these three 120 ° of connecting plate spaces and connect the outer rings of bonnet and inner annular plate respectively radially.
The invention has the beneficial effects as follows: can realize low cost better, the purpose of low energy consumption, high environmental protection, the windage and the noise of reduction range hood improve the pump drainage effect.

Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; The embodiment of the invention has proposed a kind of cooking-fume exhauster blower volute that is provided with oil smoke dashpot 7; Of the present invention focusing on comprises protecgulum 1, bonnet 2, ring-type spiral case 3, flow distribution plate 4 and oil smoke dashpot 7, and the two ends of this ring-type spiral case 3 connect protecgulum 1 and bonnet 2; This protecgulum 1 is respectively equipped with circular preceding intake grill 11 and rear air inlet 21 with bonnet 2; The center of circle vertical symmetry of intake grill 11 and rear air inlet 21 before being somebody's turn to do, the two ends of this flow distribution plate 4 are respectively equipped with bending edge 8, and this bending edge 8 is connected fixing respectively with the lower end of protecgulum 1 and bonnet 2; These flow distribution plate 4 bottom curved surface indents form an arcuation oil smoke dashpot 7, and this oil smoke dashpot 7 extends to the both sides of flow distribution plate 4.This flow distribution plate 4 is individual components non-and protecgulum 1 and bonnet 2 integrative-structures, and flow distribution plate 4 lower ends are provided with oil collecting hole 6.The curved surface cross section of this flow distribution plate 4 is divided into five sections, the arc section CD of middle indent, and the front side straightway AB of protecgulum 1 lower end and front side curved section BC, the rear side straightway EF of bonnet 2 lower ends and rear side curved section DE connect for smooth transition between the adjacent segment.This front side straightway AB be 32 ° perpendicular to the horizontal plane angle of protecgulum 1, this rear side straightway EF is 52 ° with horizontal plane angle perpendicular to bonnet 2.This volute of blower edge contour is straight line AB, curve B C, circular arc C D, curve D E and the straight line EF of rounding off are formed by connecting successively; This straight line AB and curve B C are tangential on a B; Curve B C and circular arc C D are cut in a C outward; Circular arc C D and curve D E are cut in a D outward, and curve D E and straight line EF are tangential on an E.This bonnet 2 is provided with electric machine support 5, this electric machine support 5 by an inner annular plate 51 and three radially connecting plate 52 constitute these three 120 ° of connecting plate 52 spaces and connect bonnet 2 respectively and the outer rings of inner annular plate 51 radially.
In this specific embodiment,, a kind of cooking-fume exhauster blower volute of the present invention is installed in the range hood like Fig. 1, Fig. 2 and shown in Figure 3; When range hood is worked; Oil smoke rises from the lower end of flow distribution plate 4, and under the suction function of range hood, oil smoke at first gets into oil smoke dashpot 7; Because oil smoke dashpot 7 is the circular arc design of indent, make the oil smoke air-flow obtain enough bufferings and preceding intake grill 11 of the water conservancy diversion of taking advantage of a situation entering and rear air inlet 21.The embodiment of the invention, owing to efficiently solve an oil smoke buffering water conservancy diversion difficult problem of the prior art, design principle meets the fluid mechanics principle of air-flow more; Thereby can realize low cost better; The purpose of low energy consumption, high environmental protection, the windage and the noise of reduction range hood improve the pump drainage effect.
