Problems solved by technology

Due to the open structure of the smoke collecting hood, the traditional range hood can no longer meet the needs of consumers
The near-suction range hood is favored by consumers because it is superior to traditional range hoods in terms of appearance and function, but the near-suction range hood also has the following disadvantages: one is to lose the effect of holding smoke, In addition, since the air inlet of the range hood directly faces the operator, the smell of oil fume caused by the return air will directly affect the health of the operator and pollute the kitchen environment

Embodiment 1

[0023] The structure diagram of the present invention is as figure 1 , 2 As shown, it includes a box body 1, a smoke collection hood 2 installed on the box body 1, wherein the smoke collection hood 2 is equipped with an air inlet 11, which can drive the range hood to move away from the box body 1 when it is working. When the range hood is not working, it can be driven back to the driving device on the box to cover the air inlet 11 of the box 1. The driving device includes a driving mechanism and a transmission mechanism. The driving mechanism passes through the transmission mechanism and the smoke collection hood 2 connect.

[0024] In the present embodiment, the above-mentioned driving mechanism is a reduction motor 5, and the transmission mechanism includes a turbine 4, a worm 41, a first connecting rod 6 and a connecting rod 3, wherein the turbine 4 is engaged with the worm 41, and the worm 41 is engaged with the reduction motor 5. One end of the first connecting rod 6 is...

Embodiment 2

[0032] Such as image 3 , 4 As shown, the structure of the range hood in this embodiment is different from that in Embodiment 1 in that: the above-mentioned driving mechanism is a reduction motor 5, and the transmission mechanism includes a first gear 42, a second gear 43, a first connecting rod 6 and a connecting rod 3, wherein the first gear 42 meshes with the second gear 43, the second gear 43 is installed on the output shaft of the reduction motor 5, one end of the first connecting rod 6 is connected with the first gear 42, and the other end is hinged with the connecting rod 3, The connecting rod 3 is fixed on the fume collecting hood 2 . Other structures are the same as in Embodiment 1.

Embodiment 3

[0034] Such as Figure 5 , 6 As shown, the structure of the range hood in this embodiment is different from that in Embodiment 1 in that: the above-mentioned drive mechanism is an electric push rod device 10, and the electric push rod device 10 includes a drive motor 102, which converts rotational motion into linear motion The conversion mechanism and the push rod 101, the transmission mechanism includes the second connecting rod 7 and the connecting rod 3, the input end of the motion conversion mechanism is connected with the output shaft of the drive motor 102, the output end of the motion conversion mechanism is connected with one end of the push rod 101, The other end of the push rod 101 is hinged with the middle part of the second connecting rod 7 , one end of the second connecting rod 7 is connected with the box body 1 , and the other end is hinged with the connecting rod 3 which is installed on the smoke collecting hood 2 . The above-mentioned drive motor 102 is a DC s...

Abstract

The invention relates to a range hood which comprises a box body and a fume collecting hood mounted on the box body. The fume collecting hood is provided with a driving device which can drive the range hood to move away from an air inlet arranged on the box body when the range hood works and drives the range hood to move back to the box body and cover the air inlet arranged on the box body when the range hood does not work, and the driving device comprises a driving mechanism and a transmission mechanism through which the driving mechanism is connected with the fume collecting hood. The range hood is mounted above a kitchen range, the fume collecting hood can automatically adjust the opening and closing angle and can be powered on to absorb fume and clean the kitchen environment when the range hood works; and the fume collecting hood is powered off when the range hood does not work to prevent the range hood from being tainted of odor due to return air and lessen exhaust pollution to kitchen staff. The range hood of the invention enhances the working fume intake amount, simultaneously improves the oil separation effect, effectively avoids being tainted of odor due to the return air, improves the working environment of a kitchen, promotes the scientific and technological motion and has the advantages of smart design, excellent performance, convenience and practicability.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood capable of opening and closing a smoke collection hood, which belongs to the modification technology of the range hood. Background technique [0002] The range hoods currently on the market are roughly divided into three categories, Chinese-style hoods, European-style hoods, and near-suction hoods. Due to the open structure of the smoke collecting hood, the traditional range hood can no longer meet the needs of consumers. The near-suction range hood is favored by consumers because it is superior to traditional range hoods in terms of appearance and function, but the near-suction range hood also has the following disadvantages: one is to lose the effect of holding smoke, In addition, since the air inlet of the range hood directly faces the operator, the smell of oil fume caused by the return air directly affects the health of the operator and pollutes the kitchen environment.
