Description
Technical field
The utility model relates to a kind of intelligent frequency-conversion range hood.
Background technology
In prior art, range hood generally only arranges the rotating speed key of two grades or third gear, after motor speed sets, motor can not regulate the rotating speed of range hood according to actual kitchen environment or cooking method, mechanically can only work under set static stall, it cannot be made to reach the most rational duty.
Such as, boiling when cooking and the motor speed needed for quick-fried are different, very high rotating speed is not needed under normal circumstances during boiling, if open high rotating speed shelves will cause unnecessary waste of energy when boiling, also can take away the amount of heat of the kitchen range top simultaneously, cause the energy consumption of cooking to increase.
And in cooking process, the oil smoke produced or steam temperature change at any time, existing range hood is without the function detecting this change, so motor speed cannot be regulated at any time to go accurate adaptation, manually can only go continuous switching by button, cause the inconvenience in use, also not reach and meet the real demand of user, therefore, also require further improvement.
Summary of the invention
The purpose of this utility model aims to provide one can control motor speed, with the intelligent frequency-conversion range hood and the method for work thereof that make fan assembly produce suitable air quantity, to overcome weak point of the prior art in real time according to culinary art operating mode.
By a kind of intelligent frequency-conversion range hood that this object designs, comprise exhaust fume collecting hood, Control Component and fan assembly, Control Component comprises the power module, system control module and the motor drive module that are electrically connected successively, its architectural feature is, the motor of fan assembly is alternating-current variable frequency motor, and Control Component also comprises and is connected to context detection module between power module and system control module and flue negative pressure detection module; Context detection module is arranged on the air inlet of exhaust fume collecting hood, and flue negative pressure detection module is arranged on the exhaust opening place of fan assembly.
Described context detection module is one or more the combination in humidity sensor, oil smoke detecting sensor, temperature sensor and PM2.5 detecting sensor.
Described flue negative pressure detection module is wind pressure sensor.
Described exhaust fume collecting hood is provided with the display screen for the value detected by context detection module and/or flue negative pressure detection module is shown.
The utility model has following beneficial effect:
1, the utility model adopts alternating-current variable frequency motor, the speed of service of alternating-current variable frequency motor is only regulated with one piece of circuit board, thus realize infinite variable speed control, the object realizing frequency conversion is carried without the need to multi-channel control circuit, the cost of alternating-current variable frequency motor itself is low relative to DC brushless motor, and can save more space.
2, the utility model can according to cigarette machine under different environment temperatures and Air Quality, realize the work of manual mode and automatic mode, thus realize Non-follow control motor multi-change speed, or the infinitely variable speeds of Based Intelligent Control motor, meet effect that is energy-saving and cost-reducing, noise reduction.
3, the utility model according to IAQ, can also realize idle ventilatory.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model one embodiment Control Component.
Fig. 2 is the fundamental diagram of the utility model one embodiment intelligent frequency-conversion range hood.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
See Fig. 1-Fig. 2, this intelligent frequency-conversion range hood, comprise exhaust fume collecting hood, Control Component and fan assembly, Control Component comprises the power module 1, system control module 2 and the motor drive module 5 that are electrically connected successively, it is characterized in that, the motor of fan assembly is alternating-current variable frequency motor, and Control Component also comprises and is connected to context detection module 3 between power module 1 and system control module 2 and flue negative pressure detection module 4; Context detection module 3 is arranged on the air inlet of exhaust fume collecting hood, and flue negative pressure detection module 4 is arranged on the exhaust opening place of fan assembly.
Further, context detection module 3 is one or more the combination in humidity sensor (for detecting the humidity in air), oil smoke detecting sensor (for detecting the oil smoke concentration in air), temperature sensor (for detecting the temperature in air) and PM2.5 detecting sensor (for detecting the PM2.5 concentration in air).
Further, flue negative pressure detection module 4 is wind pressure sensor (for detecting in flue whether there is negative pressure).
Further, exhaust fume collecting hood is provided with the display screen for the value detected by context detection module 3 and/or flue negative pressure detection module 4 is shown, and enables operating personnel see relevant detected value the most intuitively.
The set of the detected value of context detection module 3, can reflect the data such as humidity, oil smoke concentration, temperature, PM2.5 concentration that kitchen is real-time; The detected value of flue negative pressure detection module 4, can reflect in flue whether there is negative pressure; System control module 2, according to these numerical value, is preset the operating mode of numerous alternating-current variable frequency motor, thus is realized manual multistep speed regulation or intelligent stepless speed governing.
In addition, this cigarette machine, when idle detects that the air quality of context detection module 3 is not up to standard (as excessive in PM2.5 concentration), automatically can start alternating-current variable frequency motor, realize idle ventilatory, ensure that IAQ reaches perfect condition.
The method of work of this intelligent frequency-conversion range hood, comprises the following steps:
Step one, operating personnel can initialization system control module 2 work under manual mode or automatic mode, system control module 2 continues to send instruction to motor drive module 5, make motor drive module 5 control the rotating speed of alternating-current variable frequency motor in real time, thus realize the speed governing to fan assembly;
When step 2, manual mode, operating personnel can environmentally detection module 3 and/or the value detected by flue negative pressure detection module 4 or actual culinary art operating mode, and needed for operating personnel, manually set the duty of alternating-current variable frequency motor, thus realize the manual multistep speed regulation to fan assembly;
When step 3, automatic mode, system control module 2 is the Detection of Air Quality value of detection module 3 Real-time Feedback and the flue negative pressure detected value of flue negative pressure detection module 4 Real-time Feedback environmentally, drive the work of alternating-current variable frequency motor again according to the real-time indication motor driver module 5 of the mode of operation corresponding to preset value, thus realize the intelligent stepless speed governing to fan assembly;
Step 4, manual mode and automatic mode can switch mutually, and during two-mode conflict, system control module 2 preferentially performs manual mode.
Step 5, operating personnel also can initialization system control module 2 work under idle ventilatory pattern, system control module 2 environmentally detection module 3 idle feedback Detection of Air Quality value, make motor drive module 5 start or close, thus realize carrying out idle ventilation to room air.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
