Abstract
A kind of range hood, including blower hood, are equipped with the first blower in the blower hood, and the air outlet of the first blower is equipped with smoke pipe, it is characterised in that: the second blower, and second blower and the first blower configured in fluid communication are equipped in the smoke pipe.Compared with prior art, utility model has the advantages that the range hood in smoke pipe by being arranged the second blower with the first blower configured in fluid communication in blower hood, when two blowers enable simultaneously, the wind pressure of blower fan system can be improved, and then promote smoke absorption effect.
Description
Technical field
The utility model relates to a kind of range hoods.
Background technique
The air draft flow of range hood in a state of use depends primarily on the wind pressure of cooking-fume exhauster blower system, and wind pressure is got over
Greatly, air draft flow is also bigger.When in use, oil smoke is needed through smoke exhaust pipe, check (non-return) valve and smoke evacuation the range hood of normal domestic use
Oil smoke is discharged the resistance devices such as channel, the presence of these resistance devices, so that oil smoke exists centainly at oil smoke outlet
The presence of back pressure, back pressure can largely effect on the air draft flow of kitchen ventilator.Air draft flow of the wind pressure of blower fan system to range hood
It has a positive effect, the presence of back pressure then plays negative consequence to the air draft flow of range hood.Blower function is increased currently, generalling use
The mode of rate promotes the wind pressure of blower fan system, and correspondingly, blower fan volume can become larger, and fan noise can also increase accordingly.To sum up
It is described, need to be further improved existing range hood.
Utility model content
Technical problem to be solved in the utility model be for above-mentioned state of the art, provide a kind of structure it is simple,
The good range hood of smoke absorption effect.
Technical solution adopted by the utility model to solve the above technical problems is as follows: this kind of range hood, including outside blower
Cover, is equipped with the first blower, the air outlet of the first blower is equipped with smoke pipe, it is characterised in that: in institute in the blower hood
It states and the second blower is installed in smoke pipe, and second blower and the first blower configured in fluid communication.
First blower and the second blower can be there are many patterns, it is preferable that first blower and the second blower be from
It heart blower and is serially connected.
First blower and the second blower can be there are many distribution modes, it is preferable that first blower and the second blower are equal
Vertically arranged, straight down, the air inlet of second blower is straight up for the air inlet of first blower.
Further preferably, the air outlet of first blower is opposite with the direction of air outlet of second blower.
As the preferred of any of the above-described scheme, first blower and the second blower are coaxially disposed and rotate synchronously.
Further preferably, motor is installed between first blower and the second blower, the motor has opposite set
Two output shafts set, first blower and the second blower are separately mounted on corresponding output shaft.
Compared with the prior art, the advantages of the utility model are: the range hood passes through setting and blower in smoke pipe
The wind of blower fan system can be improved when two blowers enable simultaneously in second blower of the first blower configured in fluid communication in outer cover
Pressure, and then promote smoke absorption effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Figure 1, the range hood of the present embodiment includes blower hood 1, the first blower is installed in blower hood 1
2, the air outlet of the first blower 2 is equipped with smoke pipe 3, and the second blower 4, and the second blower 4 and the first blower are equipped in smoke pipe 3
Phase 2 is in fluid communication.
First blower 2 and the second blower 4 are centrifugal blower and are serially connected.First blower 2 and the second blower 4 are vertically set
Set, the air inlet 21 of the first blower 2 straight down, the air inlet 41 of the second blower 4 straight up, also, the first blower 2 go out
Air port 22 is contrary with the air outlet 42 of the second blower 4.
In the present embodiment, the first blower 2 and the second blower 4 are coaxially disposed and rotate synchronously.Specifically, in the first blower 2
Motor 5 is installed between the second blower 4, motor 5 has two output shafts being oppositely arranged, the first blower 2 and the second blower 4
It is separately mounted on corresponding output shaft.
When range hood works, under the driving of motor 5, the first blower 2 and the second blower 4 are rotated synchronously, in two-stage wind
Under the action of machine, the wind pressure of blower fan system can be improved, and then promote smoke absorption effect.
Above description is merely a prefered embodiment of the utility model, it is noted that for those of ordinary skill in the art
For, under the premise of not departing from the principles of the present invention, a variety of remodeling or improvement can be carried out to the utility model, these are
It is considered as within the protection scope of the utility model.
