Description
Technical field
The present invention relates to refrigerator field, particularly relate to freezer component and manufacture field, more specifically relate to air course device for refrigerator.
Background technology
Current refrigerator, as shown in fig. 1, the cold air of heat exchange is completed in refrigerating chamber 22 at evaporimeter 21 place, complete the cooling of refrigerating chamber 22, the cold air of refrigerating chamber 22 enters refrigerating chamber 23 by air-guiding aisle 1 simultaneously, through the air outlet of air channel bolt 2, enter in refrigerating chamber 23, thus the food in refrigerating chamber is lowered the temperature, but the air-out direction of air outlet is single, when air outlet front has food to stop simultaneously, cannot lower the temperature to the food of refrigerator forward part, cause refrigerator indoor temperature uneven, the flowing of portion temperature higher or on the low side and air has some setbacks, thus there is dead angle, the freshness of food is not only made to be affected, and compressor also can ceaselessly high loaded process.
In order to improve cooling-down effect, industry focuses on the position that how more reasonably arranges wind passage mouth and quantitatively always by research, but effect is difficult to the design reaching expection always.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of air course device for refrigerator, solved indoor temperature distribution uneven, accomplish real without dead angle, thus guarantee food has been fresh.
In order to realize above-mentioned object, technical scheme of the present invention is:
Air course device for refrigerator, it is from top to bottom the air channel bolt of cylinder that described air-duct apparatus comprises middle part, and described air channel bolt coordinates with a liner plate and forms air channel; The cylinder of described air channel bolt offers wind passage mouth, described liner plate offers air holes in wind passage mouth corresponding position, fixed leg is formed with in corresponding position, the center projection of wind passage mouth, also include air guiding grid, described air guiding grid forms primarily of center fixed block, grid and the outer ring of mating with wind passage mouth, and described center fixed block, outer ring are connected to form entirety by grid; The center indent of described center fixed block forms the installing hole mated with fixed leg, and described air guiding grid is coaxially fixed on fixed leg rotationally by center fixed block.
Air guiding grid is creatively set to air guiding grid form rotationally by the present invention, the escape air guiding grid form of traditional rectangle or strip, thus it is uneven to utilize 360 of air guiding grid ° of rotations to efficiently solve refrigerator indoor temperature, the flowing of portion temperature higher or on the low side and air has some setbacks, thus there is the problem at cold air dead angle.Not needing to increase wind passage mouth quantity, effectively improve cold air cooling-down effect.
Due to the particularity of refrigerator structure, its air channel structure formula is assembled by air channel bolt and liner plate and is formed, and its overall structure is positioned at the backboard place of refrigerator, is therefore subject to the restriction of refrigerator overall volume, and the design of wind passage mouth can not be too complicated, and structure can not be excessive.Therefore be all generally adopt direct borehole and with the use of the technical pattern of some guide plates in prior art, thus be unlikely to overall structure to increase, affect the assembling of whole refrigerator.
The air guiding grid structure of rotary type except structure comparatively before bar shaped air guiding grid structure think more greatly, simultaneously because the in use air guiding grid of rotary type needs constantly to rotate, therefore need corresponding fixation kit, thus ensure the stability that uses, prevent air guiding grid from coming off, be shifted, and then lost efficacy.
Therefore, for the assembling particularity of refrigerator, we are open also includes contiguous block, and described contiguous block is circular ring, and one end-face outer rim outwards extends formation positive stop lug boss; Described contiguous block forms air guiding grid installation position with the end face inner ring side indent of positive stop lug boss; The center of described contiguous block is also formed with hollow fixed leg, has connection strap between described hollow fixed leg and circle ring inner wall; Described contiguous block is fixed on the fixed leg of liner plate rotationally by hollow fixed leg; Described air guiding grid is coaxially fixed on hollow fixed leg rotationally by the center indent of center fixed block.
Further, we additionally provide the rotational power presentation mode of two kinds of air guiding grids:
First kind of way is, also include driving gear, and the driven gear to engage with driving gear, the non-engagement end face inner ring side indent of described driven gear forms air guiding grid installation position, the center of described driving gear is shaped by hollow fixed leg, and three cylinders of the fixed leg on described hollow fixed leg, air guiding grid center fixed block and liner plate are coaxial.Under this mode, power is supplied to driving gear, utilizes driving gear to drive the driven gear of engagement to rotate, and drives the air guiding grid rotation be fixed together with it due to the rotation of driven gear.
The second way is, the fixed leg on described liner plate is power rotation axis.Namely utilize fixed axis directly as power, drive air guiding grid to rotate.
On the technical scheme basis of driving gear, driven gear, the non-engagement end face outer rim that we also disclose described driven gear outwards extends formation positive stop lug boss.Thus positive stop lug boss is set directly on driven gear, reduce component count, not only save assembly technology, and on the basis that performance improves, save assembly space, more meet the matching requirements of refrigerator.
Further, we are on the basis of the technical scheme of positive stop lug boss, disclose described air channel bolt and positive stop lug boss contact surface indent further, are formed at the chimeric position of positive stop lug boss coupling, and described positive stop lug boss embeds chimeric position and forms planar structure.
Thus after mounting, positive stop lug boss is embedded in the cylinder of air channel bolt, and form smooth structure with former cylindrical structure, do not affect the normal assembling of other components.
Closer, we also disclosed described coaxial fixed form is that bolt is fixed.Here coaxial fixing can be coaxial fixing between air guiding grid center fixed block with liner plate fixed leg, also can be coaxially fixing between air guiding grid center fixed block, hollow fixed leg and liner plate fixed leg.Here bolt refers to the bolt with light face screw rod.Thus improve the limited effect of air guiding grid further, improve the stability in its use procedure.
Finally, we also disclosed described grid is latticed grid, by fence in length and breadth vertical interlaced form, the angle of described fence and horizontal direction is 10 ~ 45° angle., like this in the rotation process of fence, constantly changed by the cold wind angle of its guiding blowout, cold wind is that dispersed blows out the regulated efficiency that can better improve air-flow simultaneously.
Compared with prior art, beneficial effect of the present invention:
1. wind passage mouth can 360 degree rotate freely, make the more even of indoor temperature distribution;
2. outward appearance adopts circular design, seems and fashion, innervation very more meets the aesthetic of present people;
3. solve the problem that indoor local area is overheated or excessively cold, indoor temperature becomes more actual, effectively reduces the utilization rate of compressor, energy-saving and emission-reduction.
