Description
Technical field
The utility model belongs to field of kitchen electric appliance equipment technical field, more particularly, to a kind of frequency conversion Automatic-boosting bellows.
Background technique
Integrated kitchen range bellow is the fume exhaust mechanism of integrated kitchen range, generally comprises shell, smoking port, collection cigarette channel, blower, smoke evacuation
Pipeline, smoke outlet and cover board, smoking port are located at case top, and smoke outlet is located at the side of bellows, and blower mainly includes motor, wind
Air inlet is arranged on spiral case side end face in wheel and spiral case, and air outlet is arranged in spiral case cambered surface, and air outlet passes through smoke discharging pipe and smoke evacuation
Mouth connection, wind wheel are installed in spiral case, and motor is installed on spiral case, and machine shaft is connect with wind wheel, the rotation of motor driven wind wheel,
Setting opening for passing through when blower cleaning maintenance handling, sealed with cover plate lid by opening on shell.Existing integrated environment-friendly on the market
The fan outlet of stove fume exhaust mechanism is set to spiral case cambered surface bottom, and opening is vertically oriented to lower section, connection air outlet and smoke evacuation
Mouthful smoke discharging pipe just there must be bending phenomenon, noise is big when leading to air draft；The blower loading hatch of lid capping plate is set to shell
In body rear side sidewall, general user, which uses, would generally lean on wall for rear wall when integrated kitchen range, so that needing when blower cleaning or maintenance
Mobile integrated kitchen range position, it is very inconvenient；And it is unable to adjust automatically wind speed, when smoke outlet external pressure is big, discharge fume undesirable.
Summary of the invention
The utility model mainly solves technical problem present in the above-mentioned prior art, provides a kind of frequency conversion Automatic-boosting
Bellows.
Above technical problems of the utility model are mainly solved by the following technical scheme: a kind of frequency conversion is automatic
Be pressurized bellows, including be rectangle and it is internal be cavity shell, the top of the shell is equipped with dismountable top plate, the top
Plate is equipped with smoking port, and the side of the shell is equipped with smoke outlet, and the inside of the shell is equipped with blower, and the blower includes becoming
Frequency motor, wind wheel and spiral case, the variable-frequency motor are installed in spiral case, the output end connection of the wind wheel and variable-frequency motor, institute
The side end face for stating spiral case is equipped with air inlet, and the cambered surface of the spiral case is equipped with air outlet, and the air outlet passes through smoke discharging pipe
It is connected to smoke outlet, cover board is hinged on the smoke outlet, the medial surface of the cover board is equipped with wind pressure sensor.
Preferably, the spiral case is equipped with dismountable fixed feet, since blower can occur more by force at work
Blower is fixed on shell by strong vibration by fixed feet, and avoiding blower, position shifts at work, influences wind
The normal work of machine, and noise can be effectively reduced.
Preferably, the wind pressure sensor and variable-frequency motor are all electrically connected with a computer board.
The utility model has the advantages that the design by bellows top side detachable top plate, so that blower is tieed up
It is easy to disassemble when repairing or clearing up；The design of variable-frequency motor, when the work of this bellows, blower starting, as switch position is promoted, wind
Machine speed-raising, air quantity increases, and when some is blocked on bellows air outlet, wind pressure increases, and computer board is automatic according to wind pressure
Identification, variable-frequency motor increases revolving speed automatically, reaches constant output air quantity, to common flue, negative pressure is big, the small smoke discharging effect in space not
Ideal situation thoroughly improves；By the way that the air outlet of blower to be connect with outlet flue straight tube, so that blower outlet air is smooth, can obtain
Bigger air quantity, will not detention oil smoke, and noise is effectively reduced；It is by the design of hinged closures, the smoke outlet not used is close
It seals, prevents the impurity such as dust from entering in spiral case by smoke outlet, influence the normal use of motor.

Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment: a kind of frequency conversion Automatic-boosting bellows, as Figure 1-Figure 2, including be rectangle and it is internal be cavity
Shell, the top of the shell are equipped with dismountable top plate, and the top plate is equipped with smoking port, and the side of the shell is equipped with row
Mouth, the inside of the shell are equipped with blower, and the blower includes variable-frequency motor, wind wheel and spiral case, the variable-frequency motor installation
In in spiral case, the output end of the wind wheel and variable-frequency motor is connected, and the side end face of the spiral case is equipped with air inlet, the spiral case
Cambered surface be equipped with air outlet, the air outlet is connected to by smoke discharging pipe with smoke outlet, be hinged with cover board on the smoke outlet,
The medial surface of the cover board is equipped with wind pressure sensor.
The spiral case is equipped with dismountable fixed feet, since more strong shake can occur at work for blower
It is dynamic, blower is fixed on shell by fixed feet, avoiding blower, position shifts at work, is influencing blower just
Often work, and noise is effectively reduced.
Preferably, the wind pressure sensor and variable-frequency motor are all electrically connected with a computer board.
When work, blower starting, i.e. variable-frequency motor start, and under the action of variable-frequency motor, oil smoke is from positioned at case top
Smoking port enter, and entered in blower by air inlet, be then flowed into connecting pipe from fan outlet, then from smoke evacuation
Mouth discharge.Period, computer board make variable-frequency motor increase and decrease revolving speed reach constant output air quantity, guarantee according to wind pressure automatic identification
Smoke discharging effect.When bellows do not work, cover board seals smoke outlet, prevents foreign matter from entering spiral case, influences motor work.
Finally it is pointed out that above embodiments are only the more representational examples of the utility model.Obviously, this is practical new
Type is not limited to the above embodiments, and acceptable there are many deformations.All foundation the technical essence of the utility model are to above embodiments
Made any simple modification, equivalent change and modification are considered as belonging to the protection scope of the utility model.
