It should be noted that, the poking piece 3 is matched with the corresponding fresh-ice gear concave part 11, zero-degree gear concave part 12 or fruit-vegetable gear concave part 13 through the positioning convex part 31 arranged on the surface of the poking piece 3 facing the air duct cover plate 1, so as to realize the positioning of the poking piece 3 at the corresponding gear concave part. Further, in order to ensure that when the plectrum 3 slides from the fresh-cold gear concave part 11 or the fruit-vegetable gear concave part 13 to the zero-degree gear concave part 12, the plectrum can be firmly positioned at the zero-degree gear concave part 12, namely, the situation that the plectrum 3 jumps when moving to the zero-degree gear concave part 12 is avoided, when the plectrum 3 just moves to the zero-degree gear concave part 12, on the basis that the positioning convex part 31 is matched with the zero-degree gear concave part 12, the pressing part 2 is just pressed on the limiting part 32, so that the situation that the plectrum 3 jumps when sliding to the zero-degree gear concave part 12 can be well avoided, namely, the accurate positioning of the plectrum 3 at the zero-degree gear concave part 12 is ensured, so that the air intake of the fruit box area can be accurately controlled, and further, the accurate adjustment of the temperature and humidity of the fruit box area is realized.
In addition, because the plectrum 3 of this application can realize the firm location in zero degree gear concave part 12 department, consequently, has improved the feel and the gear sense of plectrum 3 in the promotion process widely.
As shown in fig. 1b and fig. 2, in order to further optimize the air duct cover plate 1 in the above technical solution, on the basis of the above technical solution, a first slide way 14 and a second slide way 15 which is arranged opposite to and spaced apart from the first slide way 14 are respectively arranged on the air duct cover plate 1, a first convex portion 33 which is matched with the first slide way 14 is arranged on the surface of the upper end of the poking piece 3 facing the air duct cover plate 1, and a second convex portion 34 which is matched with the second slide way 15 is arranged on the surface of the lower end of the poking piece 3 facing the air duct cover plate 1. Specifically, the first protrusion 33 is movably embedded in the first slideway 14, and the second protrusion 34 is movably embedded in the second slideway 15, so that the movable installation of the plectrum 3 on the air duct cover plate 1 can be realized, and the plectrum 3 can slide along the length direction of the air duct cover plate 1 by horizontally pushing the plectrum 3.
As shown in fig. 1a, 1b, 2 and 3, it is schematically shown that at the upper end of the pick 3 an annular passage 35 is formed, which annular passage 35 is located below the first projection 33, and at the right side of the annular passage 35 a tongue 36 extending to the left side is formed, which tongue 36 forms the annular passage 35 as a U-shaped chute 37 opening to the right. It should be noted that the tongue 36 is mainly used to mount and fix the positioning protrusion 31 and the position-limiting member 32.
In another embodiment of the present application, the surface of the extending end of the tongue 36 facing the air duct cover 1 is provided with the positioning protrusion 31, and the surface of the extending end of the tongue 36 facing away from the air duct cover 1 is provided with the position-limiting component 32 corresponding to the positioning protrusion 31. That is, the positioning protrusion 31 mainly functions to match with the fresh food shift position concave portion 11, the zero-degree shift position concave portion 12, and the fruit and vegetable shift position concave portion 13, and the stopper member 32 functions to match with the pressing member 2.
As shown in fig. 3, in order to further optimize the pressing member 2 in the above technical solution, on the basis of the above technical solution, the pressing member 2 includes a horizontal portion 21 that is provided on the duct cover 1 and can extend outward through the lower chute of the U-shaped chute 37, and a vertical portion 22 that is provided at an extending end of the horizontal portion 21 and extends upward. It should be noted that the vertical portion 22 and the protruding tongue 36 are arranged at an interval, so that when the dial 3 moves to the zero-degree gear recess 12, the limiting component 32 is conveniently just embedded between the vertical portion 22 and the protruding tongue 36, and a certain amount of extrusion force is applied to the limiting component 32 through the vertical portion 22, so that the dial 3 is firmly positioned at the zero-degree gear recess 12, and a jumping situation is avoided in the process of pushing the dial 3.
In a preferred embodiment, the stop element 32 is designed as an external projection 321, the distance between the inner side of the vertical portion 22 and the outer side of the tongue 36 being equal to the wall thickness of the external projection 321. In this way, it is ensured that the vertical portion 22 can be pressed against the outer surface of the outer protrusion 321 when the dial 3 is moved to the zero-degree shift position concave portion 12, thereby achieving accurate positioning of the dial 3. It should be noted that, since the tongue 36 of the present application is made of plastic material, and thus has a certain amount of elastic deformation, by making the distance between the inner side surface of the vertical portion 22 and the outer side surface of the tongue 36 equal to the wall thickness of the external protrusion 321, on the one hand, it is ensured that the external protrusion 321 can be pressed between the vertical portion 22 and the tongue 36 by the pressing member 2, thereby ensuring the firm positioning of the pick 3 at the zero-degree shift recess 12. On the other hand, it is also ensured that the male part 321 snaps smoothly between the upright part 22 and the tongue 36.
Example 2:
this embodiment is substantially the same as embodiment 1, and for the sake of brevity of description, in the description process of this embodiment, the same technical features as embodiment 1 are not described again, and only differences between this embodiment and embodiment 1 are explained:
as shown in fig. 5 and 6, in another preferred embodiment of the present application, a third protrusion 221 extending toward the duct cover plate 1 is configured on an inner side surface of an extending end of the vertical portion 22, the limiting member 32 is configured as an inner recess 322, and the third protrusion 221 is matched with the inner recess 322. Thus, when the plectrum 3 slides to the zero-degree gear concave part 12, on the basis that the positioning convex part 31 is matched with the zero-degree gear concave part 12, the third convex part 221 is embedded in the inner concave part 322, so that the plectrum 3 can be firmly positioned at the zero-degree gear concave part 12, the phenomenon that the plectrum 3 jumps in the sliding process is avoided, and the gear feeling and the hand feeling of the plectrum 3 are greatly improved. In addition, it should be noted that, since the wall thickness of the third protrusion 221 is much smaller than that of the tongue 36, when the dial 3 needs to be moved further toward the fresh gear recess 11 or the fruit and vegetable gear recess 13, the third protrusion 221 and the inner recess 322 can be staggered by only slightly pushing the dial 3 horizontally, so that the situation that the third protrusion 221 interferes or blocks the sliding of the dial 3 is well avoided.
As shown in fig. 1b, fig. 1b schematically shows that a first air outlet 38 and a second air outlet 39 are configured at the lower end of the pick-up 3 and above the second protrusion 34 in a spaced manner. It should be noted that the first air outlet 38 and the second air outlet 39 are arranged to mainly transport the cold in the air duct to the fruit and vegetable box area of the refrigerator compartment, so as to achieve the purpose of accurately adjusting the temperature and humidity of the fruit and vegetable area.
According to the second aspect of the application, the refrigerator comprises a refrigerator body and a door body which is pivotally arranged on the refrigerator body, wherein a horizontal partition plate is arranged in the refrigerator body so as to sequentially divide the inner space of the refrigerator body into a refrigerating chamber and a freezing chamber from top to bottom.
The air duct assembly 100 is disposed on the inner container at the back of the refrigerating chamber. The duct assembly 100 may be fastened to the inner container of the rear portion of the refrigerating compartment by screws, rivets, or the like.
In a preferred technical scheme, a fruit and vegetable box is arranged at the bottom of the refrigerating chamber, a third air outlet (not shown in the figure) and a fourth air outlet (not shown in the figure) are respectively formed on the inner container at the back of the refrigerating chamber and above the fruit and vegetable box, wherein the third air outlet can be correspondingly communicated with the first air outlet 38, and the fourth air outlet can be correspondingly communicated with the second air outlet 39. Specifically, the poking pieces 3 are horizontally pushed, so that the poking pieces 3 respectively slide along the first slide ways 14 and the second slide ways 15 on the air duct cover plate 1. When the plectrum 3 is in the ice and fresh gear concave part 11, the third air outlet is correspondingly communicated with the first air outlet 38, the fourth air outlet is correspondingly communicated with the second air outlet 39, at the moment, the cold quantity input into the fruit and vegetable box area of the refrigerator cold storage chamber from the air duct is the largest, and the temperature of the fruit and vegetable box area is lower and is usually 2 to 4 degrees.
When the shifting piece 3 slides from the ice and fresh gear concave part 11 to the zero gear concave part 12, the third air outlet and the first air outlet 38 are staggered, and the fourth air outlet and the second air outlet 39 are staggered. It should be noted that the area of the third outlet in communication with the first outlet 38 is half of the area of the first outlet when all the outlets are in communication, and the area of the fourth outlet in communication with the second outlet 39 is also half of the area of the second outlet when all the outlets are in communication. At this time, the cooling capacity delivered to the vegetable box area of the refrigerator's cold room by the air duct is slightly reduced, and at this time, the temperature of the vegetable box area is usually 4 to 6 degrees.
When the shifting piece 3 slides from the zero-degree gear concave part 12 to the fruit and vegetable gear concave part 13, the third air outlet and the first air outlet 38 are completely staggered, and the fourth air outlet and the second air outlet 39 are completely staggered, so that the cold energy in the air duct is not conveyed to the fruit and vegetable box area of the refrigerator and the refrigerating chamber through the third air outlet and the fourth air outlet, but is only conveyed through the air outlet (not shown in the figure) at the upper end of the air duct, and at the moment, the temperature of the fruit and vegetable box area is relatively high and is usually 6-8 degrees.
In summary, when the temperature and humidity of the fruit and vegetable box area in the refrigerating chamber of the refrigerator need to be adjusted, the plectrum 3 can be pushed horizontally to correspondingly stay at the fresh and ice gear concave part 11, the zero gear concave part 12 or the fruit and vegetable gear concave part 13, so that the adjustment of the air intake of the fruit and vegetable box area is realized. It should be noted that, the poking piece 3 is matched with the corresponding fresh-ice gear concave part 11, zero-degree gear concave part 12 or fruit-vegetable gear concave part 13 through the positioning convex part 31 arranged on the surface of the poking piece 3 facing the air duct cover plate 1, so as to realize the positioning of the poking piece 3 at the corresponding gear concave part. Further, in order to ensure that the plectrum 3 can be firmly positioned at the zero gear concave part 12 when moving from the fresh gear concave part 11 or the fruit and vegetable gear concave part 13 to the zero gear concave part 12, namely, to avoid the situation that the plectrum 3 jumps when moving to the zero gear concave part 12, when the plectrum 3 just moves to the zero gear concave part 12, on the basis that the positioning convex part 31 is matched with the zero gear concave part 12, the pressing part 2 is just pressed on the limiting part 32, so that the situation that the plectrum 3 jumps when sliding to the zero gear concave part 12 can be well avoided, namely, the accurate positioning of the plectrum 3 at the zero gear concave part 12 is ensured, so that the air intake of the fruit and vegetable box area can be accurately controlled, and further, the accurate adjustment of the temperature and humidity of the fruit and vegetable box area is realized.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
