Description
Technical field
The present invention relates to kitchen utensils technical fields, and in particular to a kind of range hood and the device with range hood.
Background technique
Cigarette stove all-in-one machine was fast-developing in recent years because of its compact structure and preferable smoking ability, had become
An important classification in range hood.Cigarette stove all-in-one machine on the market is broadly divided into fixed, lift and convertible now.
The exhaust fume collecting hood of fixed all-in-one machine be fixedly mounted, structure is simple, but cannot hide, cause do not need using when according to
Biggish space can so be occupied.The exhaust fume collecting hood of convertible all-in-one machine can be rotated by shaft, cover kitchen range, but due to kitchen range
Waste heat and there may be danger.The exhaust fume collecting hood of lift all-in-one machine can be risen when in use by lifting drive, be used
It can drop to below cabinet and hide after complete, not only can satisfy normal use, but also can be larger to avoid occupying when not in use
Space.But existing lift all-in-one machine, exhaust fume collecting hood are usually vertical shape structure, exhaust fume collecting hood direction is arranged in air inlet
The side of kitchen range, when in use, the oil smoke of kitchen range discharge can move upwards, and are not easy to be located at lateral air inlet sucking, cause
The lift all-in-one machine of this form to hold together cigarette effect poor.
Summary of the invention
Therefore, the technical problem to be solved in the present invention is that overcome lift cigarette stove all-in-one machine in the prior art holds together cigarette

The present invention also provides a kind of devices with range hood, including above-mentioned range hood.
The device with range hood is cigarette stove all-in-one machine.
Technical solution of the present invention has the advantages that
1. range hood provided by the invention, comprising: body is equipped with accommodating chamber；Fume collecting hood is liftably installed on
On the body, the fume collecting hood has the unfolded state for stretching out the accommodating chamber, and is placed in the accommodating chamber
Receiving state；The fume collecting hood includes at least one level exhaust fume collecting hood, and includes first order collection in at least one level exhaust fume collecting hood
Petticoat pipe, when the first order exhaust fume collecting hood is in the state stretched out upwards by the body or adjacent level exhaust fume collecting hood, described first
The top of grade exhaust fume collecting hood is tilted relative to bottom towards the side with kitchen range；It is equipped at least on the first order exhaust fume collecting hood suitable
In the air inlet for entering oil smoke；At least one driving device is suitable for driving the fume collecting hood in the unfolded state and institute
It states and switches between receiving state.When using range hood, driving device drives fume collecting hood to unfolded state, is not using
When range hood, driving device drives fume collecting hood to receiving state, drives fume collecting hood being unfolded by driving device
Switch between state and receiving state, not only can satisfy the normal use of range hood, but also can be to avoid collecting cigarette when not in use
Cover structure occupies biggish space.Meanwhile by being in the first order exhaust fume collecting hood by the body or adjacent level exhaust fume collecting hood
When the state stretched out upwards, tilts the top of first order exhaust fume collecting hood towards the side with kitchen range relative to bottom, using
When, the oil smoke of kitchen range discharge can be stopped during rising by the inclined part, thus be collected at below the sloping portion,
To be sucked by air inlet, has and preferably hold together cigarette effect.
2. range hood provided by the invention, the longitudinal section of the first order exhaust fume collecting hood is in arcuation.It can make first in this way
Grade exhaust fume collecting hood to hold together cigarette more smooth.
3. range hood provided by the invention, the fume collecting hood includes at least two-stage exhaust fume collecting hood, adjacent two-stage collection
Petticoat pipe is interconnected when the fume collecting hood is in the unfolded state.By the way that fume collecting hood is arranged to include at least
Two-stage exhaust fume collecting hood makes exhaust fume collecting hoods at different levels are opposite to be unfolded, and interconnect, need to only make first order exhaust fume collecting hood so when in use
The exhaust fume collecting hood of non-close body, the height of air inlet can be equal to first order exhaust fume collecting hood and between body other collection cigarettes
The height of cover is superimposed, and can sufficiently meet the needs of to air inlet open height；And when not using range hood, it only need to be by exhaust fume collecting hood
Structure is retracted in accommodating chamber, at this point it is possible to realize adjacent two-stage exhaust fume collecting hood fume collecting hood be in receiving state up to
Small part overlapping, so, the whole height of the fume collecting hood after storage can be lower than the superposition after exhaust fume collecting hoods at different levels be fully deployed
Highly, the height of accommodating chamber can be reduced to a certain extent in this way, and then reduce the height of body.
4. range hood provided by the invention, the transmission mechanism includes: at least one first order pulley, is fixed at institute
It states on the exhaust fume collecting hood of the second level；At least one first order rope, one end are fixedly connected with the body, and the other end passes through described first
Grade pulley is fixedly connected with the first order exhaust fume collecting hood；At least one second level pulley, is fixed on the body；At least one
A second level rope, is wound on the power output shaft, and solid by the second level pulley and the second level exhaust fume collecting hood
Fixed connection.When needing using range hood, the power output shaft of driving device is rotated, and drives the rotation of second level rope, thus
Second level exhaust fume collecting hood is pulled to rise, the rising of second level exhaust fume collecting hood will drive the rising for the first order pulley being provided thereon, thus
It pulls the first order rope being located on first order pulley to rise, drives the first order collection cigarette for being fixedly connected on first order rope one end
Cover rises, and when the required height is reached, need to only power output shaft be made to stop operating；When needing to store exhaust fume collecting hood component,
Need to only power output shaft be made to rotate backward.Above-mentioned transmission mechanism need to can only be realized by a driving device to the
The synchronization lifting of level-one exhaust fume collecting hood and second level exhaust fume collecting hood, can either improve the integral elevating efficiency of exhaust fume collecting hood component, and can be with
The use to driving device is reduced, cost is reduced.
5. range hood provided by the invention, there are two the first order pulley tools；The first order rope also has two
It is a, and be arranged in a one-to-one correspondence with the first order pulley.The elevating movement of first order exhaust fume collecting hood can be made more steady in this way.
6. range hood provided by the invention, there are two the second level pulley tools, it is respectively arranged on the two-phase of the body
