Jet-suction type range hood

Technical Field

The utility model relates to the technical field of range hoods, in particular to an injection type range hood.

Background

A range hood is a kitchen appliance for purifying the kitchen environment. The kitchen ventilator is arranged above a kitchen stove, can rapidly pump away waste burnt by the stove and oil smoke harmful to human bodies generated in the cooking process, and exhaust the oil smoke out of a room, and simultaneously condenses and collects the oil smoke, thereby reducing pollution, purifying air and having the safety guarantee effects of gas defense and explosion prevention. The range hood needs to be cleaned regularly, oil stains are not removed in the process of simple cleaning, and the range hood needs to be cleaned by using a special cleaning agent.

The whole fans that get into of flue gas of traditional lampblack absorber cause a large amount of greasy dirt deposits on the wind wheel, and the load of wind wheel increases and efficiency reduces, and then leads to the exhaust fume effect not good to bring very big inconvenience for user's cleaning work, consequently, to above current situation, urgent need develop a penetrate and inhale formula lampblack absorber, in order to overcome not enough in the current practical application.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an injection-suction type range hood to solve the problems in the background technology.

In order to achieve the purpose, the utility model provides the following technical scheme:

an injection-suction type range hood, comprising:

a bundling tube;

the smoke extraction component is connected with the bundling pipe;

the jet pipe is positioned in the bundling pipe and is connected with the smoke extraction component; and

and the auxiliary exhaust passage and the negative pressure area are both positioned between the cluster pipe and the jet pipe.

Compared with the prior art, the utility model has the beneficial effects that:

in the in-process of smoking subassembly work, can get into supplementary exhaust passage with the oil smoke suction of outside in, and jet pipe's efflux effect in the pipe tied in a bundle through setting up, can make the effect of producing the negative pressure in the negative pressure region between efflux pipe and the pipe tied in a bundle, thereby under the effect of pressure difference, make a large amount of oil gas of flowing through in the supplementary exhaust passage, consequently, the gross displacement has been increased, the effect of oil extraction cigarette has been improved, the partial air input of smoking subassembly has also been reduced simultaneously, the inside greasy dirt deposit of smoking subassembly has been reduced promptly, be favorable to the subsequent washing cleanness of relevant user, and simple structure, energy-conserving increase, bring the facility for the user, and is worth promoting.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Specific implementations of the present invention are described in detail below with reference to specific embodiments.

Referring to fig. 1, an injection range hood provided in an embodiment of the present invention includes:

a bundling tube 3;

the smoke extraction component is connected with the bundling pipe 3;

the jet pipe 8 is positioned in the bundling pipe 3, and the jet pipe 8 is connected with the smoke extraction component; and

and the auxiliary exhaust duct 5 and the negative pressure area 6 are both positioned between the cluster pipe 3 and the jet pipe 8.

In the process of smoking subassembly work, can get into in supplementary exhaust passage 5 with the oil smoke suction of outside, and the efflux effect of efflux pipe 8 in bundling pipe 3 through the setting, can make the effect of producing the negative pressure in the negative pressure region 6 between efflux pipe 8 and the bundling pipe 3, thereby under the effect of pressure difference, make and flow through a large amount of oil gas in the supplementary exhaust passage 5, consequently, the gross displacement has been increased, the effect of oil extraction cigarette has been improved, the air input of smoking subassembly part has also been reduced simultaneously, the inside greasy dirt deposit of smoking subassembly has been reduced promptly, be favorable to subsequent the cleaning of relevant user of service, and simple structure, energy-conserving increase, bring the facility for the user, be worth promoting.

In one embodiment of the present invention, referring to fig. 1, the smoking assembly comprises:

the range hood comprises a range hood body 1, wherein the range hood body 1 is connected with a bundling pipe 3;

the fan 2 is positioned in the range hood body 1, and the output end of the fan 2 is connected with the jet pipe 8; and

and the smoke inlet 9 is positioned on the range hood body 1.

When the work of discharging external oil smoke, through the starting work of lampblack absorber body 1 and fan 2 that set up, can inhale lampblack absorber body 1 and carry to supplementary exhaust passage 5 department from smoke inlet 9 with the outside oil smoke, and through the efflux effect of efflux pipe 8 in bundling pipe 3, produce the negative pressure effect at supplementary exhaust passage 5 and increased the total displacement, in order to reach energy-conserving increase certainly, the air input that has also reduced fan 2 simultaneously is in order to reduce the deposit of oil smoke in fan 2, it is cleaner more easily.

In an embodiment of the present invention, please refer to fig. 1, which further includes: and the jet orifice 4 is connected with one end of the jet pipe 8.

The fan 2 is started to work, external gas can be pressurized and then discharged into the jet orifice 4 through the jet pipe 8, and the air flow speed at the jet orifice 4 is high, so that the pressure at the negative pressure area 6 can be reduced, and the negative pressure effect is formed.

In an embodiment of the present invention, referring to fig. 1, the jet pipe 8 has a conical structure, the negative pressure region 6 is defined between the end of the jet pipe 8 with the smaller diameter and the bundling pipe 3, and the auxiliary exhaust duct 5 is defined between the end of the jet pipe 8 with the larger diameter and the bundling pipe 3.

The conical structure of the jet pipe 8 can improve the speed of the airflow at the jet port 4 and increase the space of the negative pressure area 6, thereby being beneficial to improving the total amount of the oil smoke discharged from the auxiliary exhaust duct 5 under the action of negative pressure.

In an embodiment of the present invention, please refer to fig. 1, which further includes: and one end of the exhaust hose connector 7 is connected with the bundling pipe 3.

When a large amount of oil smoke is discharged outwards under the jet flow effect of the jet flow port 4, the oil smoke can be discharged to the outside through the exhaust hose connector 7, and meanwhile, due to the structural characteristics of the exhaust hose connector 7, the installation of a pipeline can be facilitated.
