Detailed Description
The present invention is further illustrated by the following examples, but is not limited to the details of the description.
As shown in fig. 1 to 3, according to one embodiment of the present invention, a damper assembly is disclosed, which includes a mounting base 10 and an adjusting core 20, having a mounting cavity 11, an air inlet 12 and an air outlet 13, wherein the air inlet 12 and the air outlet 13 are both communicated with the mounting cavity 11; the adjusting core 20 is rotatably disposed in the mounting cavity 11, the adjusting core 20 has a plurality of air passing channels 21, the air passing channels 21 penetrate through the adjusting core 20, the flow areas of at least two air passing channels 21 are different, and the adjusting core 20 rotates to enable the air passing channels 21 to communicate with the air inlet 12 and the air outlet 13, so as to adjust the ventilation rate of the air door assembly. The air door assembly is provided with the adjusting core 20, and the adjusting core 20 is provided with at least two air passing channels 21 with different flow areas, so that the different air passing channels 21 can be controlled to be communicated with the air inlet 12 and the air outlet 13 by rotating the adjusting core 20, and because the air passing channels 21 have different flow areas, the air volume in the different air passing channels 21 is different, so that the different air volume can be adjusted according to different temperatures in the refrigerator, and the temperature fluctuation in the refrigerator is reduced.
In addition, the traditional air door with the turnover cover needs to occupy a certain space when being opened and closed, and the air door assembly of the utility model realizes the adjustment of air quantity by arranging the adjusting core 20 and rotating the adjusting core 20, thereby greatly reducing the space occupancy rate of the air door assembly. The air door assembly integrates different air inlet modes on the same component, and the space occupied by the air door system is not increased on the basis of realizing the variable air inlet modes.
As shown in fig. 1, the damper assembly further includes a driving device 30 disposed in the mounting cavity 11, and the driving device 30 is in driving connection with the adjusting core 20. By arranging the driving device 30, the adjusting core 20 can be driven to rotate by the driving device 30, so that the ventilation quantity can be adjusted.
In this embodiment, the installation cavity 11 is further provided with an installation opening 14 communicated with the installation cavity 11, the adjusting core 20 can be installed in the installation cavity 11 through the installation opening 14, installation and maintenance are convenient, the driving device 30 can adopt a motor, and the motor can be arranged in the installation cavity 11, so that the installation space can be saved.
As shown in fig. 4, in order to avoid interference between the overfire air passages 21, the overfire air passages 21 are provided at intervals in the axial direction of the regulating core 20.
The number of the over-wind channels 21 is at least 3, and the over-current areas of the over-wind channels 21 are different. Through setting up 3 at least air passages 21, and the area of overflowing of every air passage 21 is all inequality, can realize the multiple air supply mode of air door subassembly to reduce the temperature fluctuation in the refrigerator.
In this embodiment, the number of the air passing channels 21 is three, which are a first air passing channel, a second air passing channel and a third air passing channel, wherein the flow area of the first air passing channel is the largest, the flow area of the second air passing channel is half of that of the first air passing channel, and the flow area of the third air passing channel is the smallest, and correspondingly, the air door assembly has three air inlet modes: the first is the rapid cooling mode, and it is rotatory to adjust core 20, makes air intake 12 and air outlet 13 pass through first wind passageway intercommunication, and the cold volume that gets into in the refrigerator this moment is the most, can realize rapid cooling. When the temperature in the refrigerator is reduced to 5-8 ℃ away from the set temperature difference, the adjusting core 20 rotates, the air door assembly enters a second air inlet mode, namely a slow temperature reduction mode, at the moment, the first air passing channel rotates to enter the mounting seat 10 to be separated from the air inlet 12 and the air outlet 13, the second air passing channel communicates the air inlet 12 and the air outlet 13, at the moment, the cold quantity entering the refrigerator also decreases along with the second air passing channel, and the cold storage chamber enters a slow temperature reduction state. When the temperature in the refrigerator is reduced to 1-3 ℃ away from the set temperature difference, the adjusting core 20 rotates, the air door assembly enters a third air inlet mode, namely a constant temperature mode, at the moment, the first air passing channel and the second air passing channel are both screwed into the mounting seat 10 and are in a state of being separated from the air channel, and the third air passing channel communicates the air inlet 12 with the air outlet 13. The third air passing channel has a very small flow area, so that the cold quantity entering the refrigerator correspondingly is very small, but in the state, the air door is not closed, continuous small cold quantity enters the refrigerating chamber, the part of cold quantity is used for reducing the temperature of the refrigerating chamber to the set temperature and supplementing the cold quantity lost by heat leakage of the refrigerating chamber, the state of the refrigerating chamber of the refrigerator corresponds to the state when the air door of the common air-cooled refrigerator is closed, the temperature of the refrigerating chamber of the common air-cooled refrigerator can rise due to heat leakage in the period of time, and the temperature fluctuation of the refrigerating chamber in the third air inlet mode state is far smaller than that of the common air-cooled refrigerator due to the supplement of the cold quantity lost by heat leakage.
For further energy saving, the adjusting core 20 has a sealing surface which can completely seal the air inlet 12 and/or the air outlet 13, thereby reducing energy consumption.
The mounting base 10 is of insulating foam. The mounting seat 10 not only can be structurally matched with the adjusting core 20 by taking heat-insulating foam as a material, but also is lighter and better processed, can also play a role in heat insulation, prevents cold quantity leakage, and belongs to a typical object with multiple purposes.
Preferably, as shown in fig. 4, the adjusting core 20 is cylindrical, the shape of the installation cavity 11 matches the shape of the adjusting core 20, and the air passage 21 penetrates through the adjusting core 20 along the radial direction of the adjusting core 20.
In order to avoid mutual interference between the air passing channels 21, the adjusting core 20 is provided with a plurality of strip-shaped areas 22, the strip-shaped areas 22 are distributed along the circumferential direction of the outer wall of the adjusting core 20, the strip-shaped areas 22 extend along the axial direction of the adjusting core 20, and all air openings of the air passing channels 21 are positioned in different strip-shaped areas 22. Therefore, during rotation, only one air passing channel 21 corresponds to and is communicated with the air inlet 12 and the air outlet 13 at a time, and cold air leakage can be prevented.
As shown in fig. 5, the damper assembly further includes a housing 40 having a receiving cavity in which the mount 10 is located. The housing 40 includes an upper housing 41 and a lower housing 42, the upper housing 41 and the lower housing 42 enclose a containing cavity, and the upper housing 41 and the lower housing 42 are detachably connected. The mounting base 10 can be easily assembled with other components in the refrigerator by providing the housing 40, and in addition, since the upper housing 41 and the lower housing 42 are detachably coupled, the mounting and the dismounting are more convenient.
According to another embodiment of the utility model, a refrigerator is also disclosed, which comprises the damper assembly.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Not all embodiments are exhaustive.
