Abstract
The utility model discloses a blower unit structure for a side draught type range hood. The range hood includes a blower unit and a blower box, wherein the blower unit is positioned inside the blower box, and includes a volute and an impeller; an air inlet and an air outlet are formed in the volute; the impeller is arranged in the air inlet of the volute; the air outlet of the volute extends and forms a volute tongue; the blower box includes an upper blower box and a lower blower box; the upper blower box is detachably and fixedly connected onto the upper end surface of the lower blower box; the air inlet in the volute is positioned inside the lower blower box; the volute tongue on the volute penetrates through the lower blower box and positioned in the upper blower box. Therefore, the height of the upper blower box is reduced, and the air inlet of the blower unit is nearer to a kitchen range, besides, bi-directional air inlet is realized, as a result, the lampblack absorbing effect of the range hood is greatly enhanced, air loss of air inside an air channel is reduced, and the efficiency of the complete machine is improved. The blower unit structure reasonably utilizes the space, thereby greatly reducing the packaging size and lightening the complete machine.
Description
Technical field
The utility model relates to the range hood technical field, relates in particular to a kind of side extraction cooking fume extractor blower fan group structure.
Background technology
Existing side extraction cooking fume extractor generally has blower fan overhead and two kinds of mounting means of fan underlying.Wherein, the blower fan group of blower fan overhead can be designed to double-faced ventilated, but since the air intake vent of blower fan group from kitchen range away from, thereby make the smoke absorption effect of range hood relatively poor; Although the blower fan group of fan underlying is easy to air intake smoking close to kitchen range, because the restriction of side-suction type moulding, the blower fan group can only positive (operating surface) air intake, can't be from rear side air intake or the non-constant of rear side air inlet effect.
Summary of the invention
In order to overcome defects, the utility model provides a kind of side extraction cooking fume extractor blower fan group structure, and this structure and can realize two-way air intake not only close to kitchen range, and smoke absorption effect is good.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of side extraction cooking fume extractor blower fan group structure, range hood comprises blower fan group and bellows, described blower fan group is located in the described bellows in the location, described blower fan group comprises spiral case and impeller, have air intake vent and air outlet on the described spiral case, be located in the described impeller in the air intake vent of described spiral case, the air outlet place of described spiral case has extended to form the snail tongue, described bellows are comprised of upper bellows and lower bellows, described upper bellows are removably fixed with on the upper surface of described lower bellows, wherein, be located in the air intake vent spots localization on the described spiral case in the described lower bellows, the snail tongue position on the described spiral case wore in described lower bellows and the location and was located in the described upper bellows.
As further improvement of the utility model, described lower bellows offer with described spiral case on the air inlet that is complementary of air intake vent.
The beneficial effects of the utility model are: by snail tongue position that can not air intake in the blower fan group is built in the upper bellows, the air intake position is built in the lower bellows, so both reduced the height of upper bellows, make blower fan group air intake vent from kitchen range close to, can realize two-way air intake again, greatly strengthen the smoke absorption effect of range hood, reduced the windage loss of air in the air channel, promoted the efficient of complete machine.The space utilization of this blower fan group structure is reasonable in addition, has greatly dwindled Package size, has alleviated complete machine weight.

Fig. 3 is the assembly structure schematic diagram at a visual angle of the utility model blower fan group and bellows;
Fig. 4 is the assembly structure schematic diagram at another visual angle of the utility model blower fan group and bellows.
By reference to the accompanying drawings, make the following instructions:
1---blower fan group 10---spiral case
100---air intake vent 101---snail tongue
The upper bellows of 2---bellows 20---
21---lower bellows
The specific embodiment
With reference to the accompanying drawings embodiment of the present utility model is elaborated.
A kind of side extraction cooking fume extractor blower fan group structure described in the utility model, range hood comprises blower fan group 1 and bellows 2, described blower fan group is located in the described bellows 2 in 1 location, described blower fan group 1 comprises spiral case 10 and impeller, have air intake vent 100 and air outlet on the described spiral case 10, be located in the described impeller in the air intake vent 100 of described spiral case, the air outlet place of described spiral case has extended to form snail tongue 101, described bellows 2 are comprised of upper bellows 20 and lower bellows 21, described upper bellows 20 are removably fixed with on the upper surface of described lower bellows 21, wherein, be located in the described lower bellows 21 in air intake vent 100 spots localization on the described spiral case, snail tongue 101 positions on the described spiral case wore in described lower bellows 21 and the location and were located in the described upper bellows 20.By snail tongue position that can not air intake in the blower fan group is built in the upper bellows, the air intake position is built in the lower bellows, so both reduced the height of upper bellows, make blower fan group air intake vent from kitchen range close to, can realize two-way air intake again, greatly strengthen the smoke absorption effect of range hood, reduced the windage loss of air in the air channel, promoted the efficient of complete machine.The space utilization of this blower fan group structure is reasonable in addition, has greatly dwindled Package size, has alleviated complete machine weight.
In addition in the present embodiment, described lower bellows 21 offer with described spiral case on the air inlet that is complementary of air intake vent 100.
