Abstract

The utility model relates to a low-noise cooking hood which is composed of a front cover provided with a control switch and a machine body provided with a blowing part and is connected and disassembled by a spring self-locking movable buckle, wherein, the blowing part which is connected with the machine body through a spiral casing connecting plate is composed of a middle cover, an oil fume filter screen, an annular gusset plate, an impeller and a spiral casing. The lower circle of the impeller and a lower plate of the spiral casing are in a sector opening structure, so the oil fume can enter the cooking hood from the upper part and multiaspect on the upper part, the wind resistance is reduced, the noise of the whole machine is decreased, and the environment in a kitchen is improved. Compared with the enclosed structures of the lower circle of the traditional impeller and the lower plate of the spiral casing, the utility model has a great improvement.

Description

The low noise range hood

The utility model relates to the ventilation equipment of kitchen fume exhaust.

China is present, and range hood has entered huge numbers of families, also plays really and reduces the pollution of oil smoke to kitchen environment, has also increased the kitchen noise simultaneously.Range hood develops into the present range hood that has centrifugal blower with the slim of beginning, the ability of its fume exhaust strengthens, its noise also is reduced to about 60 decibels with 65 decibels of beginning, but range hood uses after all in narrower kitchen, and just at people's head, 60 decibels noise is still very big to the pollution of environment.

The purpose of this utility model just provides the low noise range hood that a kind of noise can be lower than 50 decibels.

Embodiment of the present utility model is as follows: mainly be made up of front shroud that has gauge tap (1) and the body (2) that has an air supplying part.Front shroud (1) is connected and dismounting by spring self-locking movable button device (7) with body (2).Air supplying part mainly is made up of middle cover (3), filtering oil smoke net (6), annular buckle (9), spiral case (12), impeller (11), be fixed on the body (2) by scorpion shell connecting plate (13), it is characterized in that the following circle of impeller (11) and the lower plate of spiral case (12) are fan-shaped open-type structure, make oil smoke from upper and lower multiaspect air intake, reduce noise greatly.

Advantage of the present utility model just is that the following circle of impeller (11) and the lower plate of spiral case are fan-shaped open-type shape, make oil smoke from top, bottom multiaspect air intake, reduce windage greatly and reduced the noise (below 50 decibels) of complete machine, improve kitchen environment and pollute, have breakthrough improvement with circle and spiral case lower plate enclosed construction under original traditional impeller.

Fig. 1: perspective view of the present utility model.

Fig. 2: the utility model removes the axonometric drawing behind front shroud and the filtering oil smoke net.

Part name 1. front shrouds among the figure, 2. body, 3. in the cover, 4. the illuminating lamp door, 5. lubricating cup, 6. the filtering oil smoke net, 7. spring self-locking movable button, 8. screw, 9. annular buckle, 10. cover fastener in locking cap, 11. impellers, 12. spiral cases, the 13. spiral case connecting plates, 14..

Below in conjunction with Fig. 1, Fig. 2 installation of the present utility model, use are further described:

Install: the scorpion shell (12) (also can assemble motor later on) that will install motor links to each other with spiral case connecting plate (13), be fixed on the body again, impeller (11) is fixed on the motor shaft and locks with locking cap (10), annular buckle (9) is buckled in spiral case (12) goes up with screw (8) fixing.Middle cover (3) is made up of three of left, center, right, and mutually from embedding, middle cover fastener (14) buckles, and is fixed on spiral case fixed head (13), covers during filtering oil smoke net (6) is placed on.Front shroud (1) links to each other with body (2) and dismounting by spring self-locking movable button device (7).

During use, by " L " shape fixed frame body (2) is fixed on the wall, loads onto the energising of front shroud (1) and airduct and can use, all wiring connections are all adopted and are pressed plug-in unit in the machine, make and unpick and wash conveniently.Range hood after the improvement, noise can be lower than 50 decibels.

Claims

A kind of low noise lampblack absorber, form by front shroud that has gauge tap (1) and the body (2) that has an air supplying part, the air supplying part of its body (2) is made up of middle cover (3), filtering oil smoke net (6), annular buckle (9), spiral case (12), impeller (11), be fixed on the body (2) by spiral case connecting plate (13), it is characterized in that: the lower plate of the following circle of impeller (11) and spiral case (12) is fan-shaped open-type structure.
