Abstract

The invention particularly relates to a range hood, which comprises an air handling box, and an air extracting cavity, an air outlet and an air extracting port arranged on the air handling box, wherein an electric motor is fixed in the air extracting cavity; the rotation shaft of the electric motor is connected to a wind wheel; the air extracting port is connected to an external cover; and the inner cavity of the wind wheel is also connected with an air inducing and flow guiding wheel. The range hood has the beneficial effect that the addition of the air inducing and flow guiding wheel to the wind wheel overcomes the shortcoming of insufficient suction in the hollow part of the wind wheel, thereby improving the effect of extracting oil fume and enhancing other advantages.

Description

Smoke exhaust ventilator

Technical field

The present invention is specifically related to a kind of smoke exhaust ventilator.

Background technology

In the prior art, smoke exhaust ventilator adopts radially air supply mode of wind wheel, and air-flow will be done twice 90 degree back tracks and can discharge in the air delivery duct, and general structure is made up of casing, motor, air draft tube, wind wheel and control circuit, in its air draft tube, motor is fixed on the casing, and an end of motor is fixed with wind wheel, and its weak point is the internal friction work done and the particle exchange of vortex region, cause local energy loss, make suction inlet place suction deficiency, by the increase power of motor, thus the waste electric energy.

Summary of the invention

The objective of the invention is in order to overcome the shortcoming that prior art exists, provide a kind of energy-conservation and promote the smoke exhaust ventilator of oil suction cigarette ability.

The present invention realizes with the following methods: bag wind cabinet, and wind is provided with pumping chamber, exhaust outlet and bleeding point cashier's office in a shop, fixes a motor in the pumping chamber, and the rotating shaft of motor is connected with a wind wheel, bleeding point connects enclosing cover, and the inner chamber of its described wind wheel also is connected with the air inducing inducer.

The inner chamber of described wind wheel has cushion cap, and a joint pin is arranged on the cushion cap, and joint pin is connected in the air inducing inducer, and the rotating shaft of motor runs through cushion cap, joint pin and air inducing inducer.

Described rotating shaft end is connected with screw lid.

Be on the edge of described screw lid and raise into petal-shaped.

Described air inducing inducer is by the dish seat and radially distributes in the air blade of dish seating face.

The invention has the beneficial effects as follows: add the air inducing inducer on the basis of wind wheel, remedy attraction deficiency in vacancy in the wind wheel, thus advantages such as lifting oil suction cigarette effect.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Fig. 2 is the explosive decomposition figure of Fig. 1.

Fig. 3 is the front view of Fig. 1.

Fig. 4 analyses and observe enlarged diagram for the A-A` of Fig. 3.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is made concrete further instruction.

As shown in the figure, bag wind cabinet 1, and wind cabinet 1 is provided with pumping chamber 101, exhaust outlet and bleeding point, fix a motor 6 in the pumping chamber 101, the rotating shaft of motor 6 is connected with a wind wheel 3, and bleeding point connects enclosing cover 2, and the inner chamber of its described wind wheel 3 also is connected with air inducing inducer 4.

The inner chamber of described wind wheel 3 has cushion cap 301, and a joint pin 302 is arranged on the cushion cap 301, and joint pin 302 is connected in air inducing inducer 4, and the rotating shaft of motor 6 runs through cushion cap 301, joint pin 302 and air inducing inducer 4.

Described rotating shaft end is connected with screw lid 5.

Be on the edge of described screw lid 5 and raise into petal-shaped.

Described air inducing inducer 4 is by the dish seat and radially distributes in the air blade of dish seating face.

The middle vacancy of wind wheel 3 is provided with air inducing inducer 4, remedies attraction deficiency in vacancy in the wind wheel 3, thereby promotes oil suction cigarette effect etc.
