Detailed description of the invention
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Below with reference to the accompanying drawings describe in detail according to ducting assembly of the present utility model.
As depicted in figs. 1 and 2, according to ducting assembly 10 of the present utility model, comprising: air channel body 110, air duct cover board 120, blower fan (not shown) and air outlet baffle plate 140.
Air duct cover board 120 is connected to limit air channel 100 with air channel body 110.Air duct cover board 120 has air outlet 121.
Described blower fan is located in air channel 100.
Air outlet baffle plate 140 be connected with air duct cover board 120 and air outlet baffle plate 140 open between the primary importance of air outlet 121 and the second place of closing air outlet 121 rotatable.The opening degree of air outlet 121 and the rotating speed positive correlation of described blower fan.
That is, when rotation speed of fan is lower, air outlet baffle plate is tending towards primary importance and rotates, and to ensure that air outlet fluid reaches certain flow rate, meets the even requirement of air-supply.When rotation speed of fan raises, air outlet baffle plate rotates towards being tending towards the second place, to increase the circulation area of air outlet, reduces air outlet flow velocity, thus noise under reducing blower fan height rotating speed.
According to ducting assembly of the present utility model, the opening degree of described air outlet and the rotating speed positive correlation of described blower fan, when blower fan low-speed running, under the prerequisite that satisfied air-supply requires, the opening degree of air outlet baffle plate is little, and when blower fan runs up, the opening degree of air outlet baffle plate is greatly to increase the circulation area of air outlet, reduce air outlet flow velocity, thus noise under reducing blower fan height rotating speed.Because air outlet circulation area under high rotating speed increases, air channel windage reduces, and can reduce blower fan power consumption, raising efficiency.
According to an example of the present utility model, air outlet 121 is multiple, and air outlet baffle plate 140 is multiple one to one with multiple air outlet 121.Advantageously, multiple air outlet 121 on air duct cover board 120 along the vertical direction interval be arranged to multirow and interval is arranged to multiple row in left-right direction.
Advantageously, the opening degree of multiple air outlet 121 and the synchronization positive correlation of described blower fan.That is, when rotation speed of fan becomes large, the amplitude that the opening degree of multiple air outlet 121 increases is identical, and when rotation speed of fan reduces, the amplitude that the opening degree of multiple air outlet 121 reduces is identical.
Advantageously, the opening degree of multiple air outlet 121 respectively with the rotating speed positive correlation of described blower fan.That is, when rotation speed of fan becomes large, the amplitude that the opening degree of multiple air outlet 121 increases is different, and when rotation speed of fan reduces, the amplitude that the opening degree of multiple air outlet 121 reduces is different.
According to an example of the present utility model, air outlet baffle plate 140 is by driving stepper motor (not shown), and described stepper motor to be located in air channel 100 and to be connected to adjust the opening degree in air port 121 with described blower fan.
In other words, when rotation speed of fan is lower, driving stepper motor air outlet baffle plate is tending towards primary importance and rotates, and to ensure that air outlet fluid reaches certain flow rate, meets the even requirement of air-supply.When rotation speed of fan raises, driving stepper motor air outlet baffle plate rotates towards being tending towards the second place, to increase the circulation area of air outlet, reduces air outlet flow velocity, thus noise under reducing blower fan height rotating speed.
According to an example of the present utility model, ducting assembly 10 also comprises the temperature sensor (not shown) of the temperature for detecting refrigeration compartment, the temperature signal positive correlation of the described refrigeration compartment that the opening degree of air outlet 121 and described temperature sensor detect.Namely, when temperature sensor detects that a certain regional temperature of refrigeration compartment is greater than predetermined temperature, the opening degree increasing the air outlet 121 corresponding with this region increases air quantity to freeze, when temperature sensor detects that a certain regional temperature of refrigeration compartment is less than predetermined temperature, the opening degree reducing the air outlet 121 corresponding with this region reduces air quantity and freezes to reduce.
When being applied on the refrigeration plants such as refrigerator according to ducting assembly 10 of the present utility model, when rotation speed of fan is lower, air outlet baffle plate is tending towards primary importance and rotates with the opening degree reducing air outlet, ensures that air port fluid reaches certain flow rate, meets the even requirement of air-supply; When rotation speed of fan raises, air outlet baffle plate is tending towards the second place and rotates with the opening degree increasing air outlet, thus increases the circulation area of air outlet, reduces air outlet flow velocity, thus noise under reducing blower fan height rotating speed.Because air outlet circulation area under high rotating speed increases, air channel windage reduces, and can reduce blower fan power consumption, raising efficiency.Coordinating temperature sensor, by adjusting air port opening degree size to change diverse location air force, thus diverse location temperature more being satisfied the demands, improve and promote temperature homogeneity, realize accurate temperature controlling.
