Abstract
An energy-saving smoke sucking machine. Through the alteration of the snail shell structure of an intake and an outtake, the good matching is made between the intake, the outtake and a snail shell, a worm wheel, a motor and other components; the performance of the sucking and exhausting system of the whole smoke sucking machine is improved; the sucking and exhausting air amount at low power is made large, thus saving the energy and reducing the product cost. The utility model has the advantages of that the invention has good sucking and exhausting effects, good suction, low energy consumption, low cost, etc.
Description
Affiliated technical field
The utility model relates to the improvement of suction-discharge type range hood, especially relates to the improvement of range hood suction and discharge system.
Background technology
Along with the improvement of people's lives, people are more and more higher to the requirement in kitchen, and kitchen clean quiet proposed very high requirement, and the range hood product becomes the necessity of family kitchen equipment now.At present commercially available range hood is common to exist following defective:
(1) range hood generally adopts the method for expanded motor power to improve suction, reaches the purpose that blots the absolute oil cigarette with this.This kind mode can cause great energy consumption, and energy utilization rate is low, and power consumption is big, and causes the obvious increase of product cost.
(2) range hood air inlet and air outlet adopt common straight structure, and the position is also very short, and the air inlet diameter is excessive, cause and not the matching of motor, wind wheel, spiral case etc., thereby range hood does not form good air force absorbing path, the fume exhaust weak effect of machine, and energy loss is big.
Summary of the invention
The purpose of this utility model is by the architecture advances to range hood air inlet and air outlet, to improve the suction and discharge systematic function of whole range hood, make the air quantity of fume exhaust under the situation of smaller power big, thereby energy savings to reduce product cost.
The utility model is achieved through the following technical solutions: a kind of energy-saving range hood, form by housing (1), spiral case (2), worm gear (3), motor (4), air inlet (5), air outlet (6), air inlet (5) is an elongated Venturi tube structure, its outer end is bigger, and the radius of the arc surface (7) of air inlet (5) is 2.5 times of air inlet (5) minimum dimension position (8) radius; Air outlet (6) is elongated diffusion cylinder structure, and its outer end is bigger, and tapering is 5 to 10 degree; The minimum interior diameter of air inlet (5) is bigger more than 20% than the minimum diameter of air outlet (6).Like this, the air inlet of range hood, air outlet and motor, wind wheel, spiral case etc. just can form good coupling, greatly in the efficient that improves its fume exhaust, but under the less situation of power of motor the also bigger air quantity of suction, saved the energy.
Advantage of the present utility model is that the suction of product is effective, and suction is good, and energy consumption is little, and cost is low, has remarkable energy saving effect.
Description of drawings
Below provide embodiment, the utility model is further described.
Fig. 1 is the structural representation of the utility model deep suction type machine.
Fig. 2 is the structural representation of the European machine of the utility model.
The specific embodiment
Embodiment 1 (Fig. 1):
A kind of energy-saving range hood, its surface structure is a deep suction type, form by housing (1), spiral case (2), worm gear (3), motor (4), air inlet (5), air outlet (6), air inlet (5) is an elongated Venturi tube structure, its outer end is bigger, and the radius of the arc surface (7) of air inlet (5) is 2.5 times of air inlet (5) minimum dimension position (8) radius; Air outlet (6) is elongated diffusion cylinder structure, and its outer end is bigger, and tapering is 5 to 10 degree; The minimum interior diameter of air inlet (5) is bigger more than 20% than the minimum diameter of air outlet (6).Like this, the air inlet of range hood, air outlet and motor, wind wheel, spiral case etc. just can form good coupling, greatly in the efficient that improves its fume exhaust, but under the less situation of power of motor the also bigger air quantity of suction, saved the energy.
Embodiment 2 (Fig. 2):
With embodiment 1, just its surface structure is European structure.
Claims (2)
1. energy-saving range hood, form by housing (1), spiral case (2), worm gear (3), motor (4), air inlet (5), air outlet (6), it is characterized in that air inlet (5) is an elongated Venturi tube structure, its outer end is bigger, and the radius of the arc surface (7) of air inlet (5) is 2.5 times of air inlet (5) minimum dimension position (8) radius; Air outlet (6) is elongated diffusion cylinder structure, and its outer end is bigger, and tapering is 5 to 10 degree.
2. range hood according to claim 1 is characterized in that the minimum interior diameter of air inlet (5) is bigger more than 20% than the minimum diameter of air outlet (6).
