Abstract
The utility model provides a ventilator which comprises a shell, a scroll casing, a scroll casing flange and a blower. An air outlet of the scroll casing is connected with an air outlet of the shell. The utility model is characterized in that the joint between the air outlet of the scroll casing and the air outlet of the shell is horn shaped. The horn opening is the air outlet of the scroll casing with the shape of a wide top and narrow bottom square horn opening. The square horn opening of the scroll casing is connected with the outlet of the shell through the scroll casing flange. The top air outlet of the shell of the ventilator is with standard size and only changing the joint between the air outlet of the scroll casing and the air outlet of the shell to horn opening shape. The utility model can lesson (or largen) the vertical size of the scroll casing in the blower to increase (or reduce) the air inletting area, therefore realizes the rational adjustment of the subpressure generated in the air inletting area and the scroll casing to fully exert the functions of the ventilator.
Description
Technical field
The utility model belongs to kitchen hood, is the improved kitchen hood of a kind of worm frame specifically.
Background technology
Existing European kitchen hood has plenty of spiral case is placed in the square casing at kitchen hood top on the market, impeller in the spiral case is rotated by driven by motor, form negative pressuren zone on spiral case top, oil smoke by air intake zone process, enters spiral case under the effect of negative pressure, oil smoke is through behind the impeller, oil smoke separates, and waste gas is discharged by air outlet, enter be discharged in the smoke discharging pipe that is connected with air outlet on the casing outdoor.Because of the cross section and the smoke discharging pipe of the air outlet on the casing is generally general standard size, and the air outlet on spiral case exhaust outlet and the casing top is measure-alike.Like this, place because of existing spiral case in the casing of European kitchen hood, if the spiral case size is bigger, then the air intake zone of casing air inlet is just smaller, the size in air intake zone enters how much being directly proportional of spiral case with oil smoke, the negative pressure ratio that forms in air intake zone and the spiral case is unreasonable, and the function of lampblack absorber is not fully exerted.
Summary of the invention
The purpose of this utility model is to provide a kind of kitchen hood at the deficiencies in the prior art, under the constant situation of lampblack absorber case top air outlet and spiral case flange size, only by changing the shape of spiral case, make the air outlet on spiral case exhaust outlet and the lampblack absorber case top easy to connect, needs that can the applied code part, be convenient to again to realize the negative pressure that forms in air intake zone and the spiral case is reasonably adjusted, so that the function of lampblack absorber is not fully exerted.
The technical solution of the utility model is: a kind of kitchen hood, comprise casing, spiral case, spiral case flange, blower fan, the spiral case exhaust outlet is connected with air outlet on the casing, it is characterized in that described spiral case exhaust outlet and casing air outlet coupling part are the horn mouth shape.
Described horn mouth is the exhaust outlet of spiral case, and it is shaped as up big and down small square horn mouth.
The square horn mouth of described spiral case is connected with air outlet on the casing by the spiral case flange.
The utility model compared with prior art has many advantages and good effect:
1, for adapting to the needs of standard universal spare, the air outlet of lampblack absorber case top is a standard size, and under the situation of casing air inlet and spiral case flange size inconvenience change, only spiral case exhaust outlet and casing air outlet coupling part is become the horn mouth shape.Can easily spiral case be diminished at the blower fan axial dimension (or become big), thereby increase (or reducing) air intake zone, be convenient to realize that the negative pressure to forming in air intake zone and the spiral case reasonably adjusts, so that the function of lampblack absorber is not fully exerted.
2, simple in structure, handsome in appearance, cost is lower, is convenient to implement.
Description of drawings
Fig. 1 is the partial structurtes front view of the utility model lampblack absorber spiral case;
Fig. 2 is the utility model spiral case mounting structure schematic diagram.
The specific embodiment
Referring to Fig. 1, a kind of kitchen hood, comprise casing 4, spiral case 3, spiral case flange 1, blower fan, lampblack absorber housing 4 top outlet inlets are standard size, and under the situation that the inconvenience of casing 4 air inlet sizes changes, for realizing that the negative pressure that forms in air intake zone and the spiral case is reasonably adjusted, so that the function of lampblack absorber is not fully exerted.Need suitably reduce the axial size of spiral case 3 blower fans, strengthen the air intake zone, the exhaust outlet 2 of spiral case 3 is arranged to up big and down small square horn mouth, the tubaeform exhaust outlet 2 of spiral case 3 is connected with air outlet solder joint on the casing 4 by standard-sized spiral case flange 1.
Another kind of kitchen hood, lampblack absorber housing 4 top outlet inlets also are standard size, for realizing that the negative pressure that forms in air intake zone and the spiral case is reasonably adjusted, when the axial size of spiral case 2 blower fans is big, for the exhaust outlet 2 that makes spiral case 3 docks with lampblack absorber housing 4 top outlet inlets are convenient, the exhaust outlet 2 of spiral case 3 is arranged to up-small and down-big square horn mouth, and the exhaust outlet of spiral case 32 is connected with air outlet solder joint on the casing 4 by standard-sized spiral case flange 1.
Claims (3)
1, a kind of kitchen hood comprises casing, spiral case, spiral case flange, blower fan, and the spiral case exhaust outlet is connected with air outlet on the casing, it is characterized in that described spiral case exhaust outlet and casing air outlet coupling part are the horn mouth shape.
2, according to the described kitchen hood of claim 1, it is characterized in that described horn mouth is the exhaust outlet of spiral case, it is shaped as up big and down small square horn mouth.
3,, it is characterized in that the square horn mouth of described spiral case is connected with air outlet on the casing by the spiral case flange according to claim 1 or 2 described kitchen hoods.
