Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Specific example 1: referring to fig. 1 to 4, in the embodiment of the present invention, a novel range hood includes a range hood housing 1, the range hood housing 1 includes an upper housing 101 and a lower housing 102, a fan 2 and a venturi tube 3 are installed in the upper housing 101, the fan 2 is coaxially and fixedly connected to one end of the venturi tube 3, an air inlet 101-1 and a smoke outlet 101-2 are respectively disposed above the upper housing 101, the fan 2 is disposed in the air inlet 101-1, the other end of the venturi tube 3 is communicated with the smoke outlet 101-2, a smoke inlet channel 6 is disposed on the lower housing 102, a smoke inlet pipe 5 is disposed below the venturi tube 3 and communicated with the smoke inlet channel 6, the smoke inlet pipe 5 is communicated with the venturi tube 3, a plurality of pressure pipes 4 are disposed on an outer wall of the venturi tube 3, both ends of the pressure pipes 4 are communicated with the venturi tube 3 and are disposed outside the venturi tube 3 in an arc shape, the pressurizing pipe 4 is arranged at the same side of the smoke inlet pipe mouth 5. The internal diameter of the pressure pipe 4 decreases progressively from left to right in proper order to this forms that the air inlet is big, and the effect that the air-out is little lets the pressure pipe 4 form in great wind pressure entering venturi 3.

Venturi 3 from left to right is venturi entry 301, choke 302 and venturi export 303 respectively in proper order, venturi entry 301 is connected with fan 2, it is linked together with venturi entry 301 to advance tobacco pipe mouth 5, it is linked together with venturi entry 301 to pressurize pipe 4, venturi export 303 and outlet flue 101-2 intercommunication. The left end of the pressurization pipe 4 is communicated with the venturi tube inlet 301, the right end of the pressurization pipe 4 is obliquely inserted into the venturi tube 3 and faces the direction of the throat 302, in the embodiment, the outer wall of the venturi tube 3 is provided with four pressurization pipes 4 with the same structure along the circumferential direction of the transverse axis of the venturi tube 3 to perform physical pressurization operation on the venturi tube 3, so as to ensure that oil smoke can be quickly absorbed.

The lower shell 102 comprises a first shell 102-1 arranged transversely and a second shell 102-2 arranged longitudinally, the second shell 102-2 is mounted at the rear side of the first shell 102-1, an L-shaped structure is formed between the second shell 102-2 and the first shell 102-1, a smoking grid plate 103 used for smoking is arranged on the second shell 102-2, the smoking grid plate 103 is communicated with the smoke inlet channel 6, and a function key area 7 is arranged outside the first shell 102-1. An illumination area 8 is arranged below the first shell 102-1, and the illumination area 8 is arranged on the front side of the second shell 102-2.

The working process is as follows: firstly, the smoke exhaust ventilator is installed, the fan 2 is started, the working gas enters the Venturi tube 3 from the outlet of the fan 2, the speed of the airflow is increased sharply after passing through the throat tube 302, negative pressure is formed, the oil smoke generated by cooking is pressed into the smoke exhaust ventilator by atmospheric pressure, the smoke firstly passes through the smoke inlet grid plate and enters the inlet 301 of the Venturi tube through the smoke inlet channel 6, the smoke and the working gas perform momentum exchange at the throat tube 302, the smoke exhaust ventilator is exhausted after diffusion at the outlet 303 of the Venturi tube, the smoking process is completed, the pressure in the Venturi tube 3 is changed by utilizing the characteristics of the Venturi tube 3, and therefore the oil smoke can achieve the effect of absorbing the oil smoke without passing through the fan 2.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
