Description
Technical Field
The present invention relates to a refrigerator.
Background
In order to effectively use a storage space in a refrigerator, for example, a plurality of shelves for partitioning the inside of a refrigerating chamber are provided side by side in the up-down direction. For the same purpose, a plurality of storage shelves are provided in parallel in the up-down direction on the inside of a heat insulating door opening the front surface of a refrigerator compartment.
However, in a general refrigerator, the positions of the shelf and the receiving rack are fixed. In contrast, the stored objects have various heights depending on the type, packaging form, and the like. Thus, when the height position of the shelf or the storage rack is fixed, an empty area is created between the stored object and the shelf or the storage rack arranged directly above it. Since the empty area becomes an ineffective area where the stored objects cannot be placed, effective use of the storage space in the refrigerator is hindered. For example, the following patent documents 1 and 2 disclose techniques for eliminating an ineffective area in such a refrigerator.

In addition, in the refrigerator according to the present invention, the upper surface of the second recessed area has an opening, one end side of the locking lever is rotatably connected to the front end portion of the upper surface by a rotation shaft, and the locking lever is rotatable to the other end side of the locking lever to be accommodated at the opening of the upper surface.
In the refrigerator according to the present invention, the collision convex portion protrudes downward from the bottom portion on the other end side and collides with the claw portion of the rotating body.
[ Effect of the invention ]
According to the present invention, by providing the rib protruding outward from the side wall of the storage rack and the storage rack height position adjusting portion including the rail groove that functions as a moving path in the up-down direction thereof when the rib is embedded therein, the storage rack can be moved in the up-down direction. Further, the storage rack can be fixed by moving the storage rack to a predetermined height position and engaging the first convex portion of the rib with the first concave portion of the rail groove at the same time as engaging the second convex portion of the rib with the second concave portion of the rail groove. Accordingly, the height position of the storage rack can be appropriately adjusted in accordance with the height of the object to be stored in the storage rack, and therefore, occurrence of an ineffective area can be suppressed. Accordingly, the storage space of the stored object provided on the rear surface side of the heat insulating door can be effectively utilized as compared with the conventional refrigerator in which the height position of the storage rack is fixed. Further, as described above, the height position of the storage rack can be adjusted by a simple structure of the first and second protrusions of the rib and the first and second recesses of the rail groove, so that it is possible to prevent the cost of the refrigerator from being excessively increased.
Further, according to the present invention, by the track groove being wider than the rib, a minute gap can be formed between the track groove and the rib. By this, the rib in the rail groove is inclined by the rear side of the storage rack being raised or lowered as compared with the front side, and the engagement of the first convex portion with the first concave portion and the engagement of the second convex portion with the second concave portion are released. As a result, the storage rack fixed at the predetermined height position can be returned to the state of being movable up and down. According to this aspect, the fixation of the storage rack can be released by the simple operation as described above. Thus, the height adjustment work of the storage rack can be easily performed.
In addition, according to the present invention, when the storage rack is to be lowered, the claw portion of the rotating body collides with the collision convex portion of the lock lever, and the rotation of the claw portion is locked. Then, in addition to the engagement of the first convex portion of the rib with the first concave portion of the rail groove and the engagement of the second convex portion of the rib with the second concave portion of the rail groove, this aspect of the invention can also fix the storage rack at a specified height position by both of the rotation locking structures of the claw portions of the locking lever described above. Thus, according to the present invention, even if the engagement between the first convex portion of the rib and the first concave portion of the rail groove or the engagement between the second convex portion of the rib and the second concave portion of the rail groove is insufficient, the lowering of the storage rack can be prevented by the rotation lock structure of the claw portion of the lock lever. As a result, the storage rack can be effectively prevented from accidentally falling down, and safety can be ensured. In addition, the ascending movement of the storage rack is assisted by the engagement of the pinion and the rack.
Further, according to the present invention, when the storage rack is lifted, the inclined surface of the claw portion collides with one surface of the collision convex portion and pushes the collision convex portion, so that the claw portion is allowed to rotate in conjunction with the lifting of the storage rack, and when the storage rack is to be lowered, the vertical surface of the claw portion collides with the other surface of the collision convex portion, so that the locking claw portion rotates in conjunction with the lifting of the storage rack. Thus, according to the present invention, since the rotation of the claw portion linked to the raising of the storage rack is not hindered, the storage rack can be raised without increasing an excessive work load, and since the rotation of the claw portion linked to the lowering of the storage rack is hindered by the lock lever, it is possible to effectively prevent the storage rack from accidentally falling down. Thereby, convenience and safety can be improved at the same time.
Further, according to the present invention, since the height position of the upper storage rack can be adjusted in accordance with the height of the stored object stored in the lower storage rack, the rib for preventing overturning can be arranged at an appropriate position in accordance with the height of the stored object. Thus, even if objects with different heights are stored in the storage rack each time, the objects can be prevented from falling over.

As shown in fig. 7, the plurality of first concave portions 311 are disposed side by side in sequence along the height direction of the rail groove 31. The plurality of first recesses 311 shown in the drawing are arranged at equal intervals, but is not limited thereto.
In addition, a plurality of second concave portions 312 recessed rearward are respectively recessed in the second side walls 31S2 of the rail grooves. As shown in fig. 7, the plurality of second concave portions 312 are disposed side by side in sequence along the height direction of the rail groove 31. The plurality of second recesses 312 are shown to be arranged at equal intervals in the drawing, but is not limited thereto.
As shown in fig. 8, the rail groove 31 is wider than the rib 21 of the storage rack 20, and the rib 21 is fitted into the rail groove 31. In this state, the rib 21 moves up and down, and the first convex portion 211 thereof reaches the position of the first concave portion 311 of the rail groove 31. Thereby, the first convex portion 211 engages with the first concave portion 311. Similarly, the second convex portion 212 of the rib 21 reaches the position of the second concave portion 312 of the rail groove 31. Thereby, the second convex portion 212 engages with the second concave portion 312. In this way, the storage rack 20 can be supported not only by the storage rack position adjusting portion 30 but also to a predetermined arbitrary height position along the extending direction of the rail groove 31, that is, the up-down direction by means of the ribs 21.
As shown in fig. 8, the rack 32 of the rack position adjustment unit 30 in the present embodiment is engageable with a pinion gear 222 provided on the rotating body 22 of the rack 20. Thus, the rack 32 is provided at a position opposed to the pinion gear 222. Although not particularly limited, the rack 32 in the present embodiment is formed along the height direction of the front side outer wall 33 of the storage rack height position adjusting portion 30.
Referring to fig. 1, a pair of storage rack height position adjustment portions 30a and 30b in the present embodiment are provided substantially parallel to the back side of the heat insulation door 10. Therefore, as long as the storage rack 20 is provided with the ribs 21a and 21b, the ribs 21a and 21b are provided with the first convex portion 211 and the second convex portion 212 that cooperate to adjust the height position, and the distance between the ribs 21a and 21b is substantially constant, the storage rack height position adjusting portion 30 can be applied even if the storage rack 20 is different in shape. Further, even if the number of storage racks 20 is increased as needed, the storage racks 20 can be easily assembled to the storage rack height position adjustment section 30.
In the present embodiment, the storage rack height position adjustment portion 30 is mounted as a separate member inside the protruding walls 121a and 121b of the inner package panel portion 12, but the mounting manner is not limited thereto. For example, in other embodiments, the inner sides of the protruding walls 121a and 121b of the inner package panel portion 12 are provided with a long-sized concave space in the height direction, and the concave space serves as the rail groove 31, so that the protruding walls 121a and 121b correspond to the storage rack height position adjustment portion. Of course, the technical scheme of the invention is not limited to this.
Action
Next, the fixing of the height position of the storage rack 20 and the releasing operation thereof will be described with reference to fig. 9. Here, fig. 9a is the same view as fig. 8, and shows a state in which the storage rack 20 is fixed at a designated height position. Fig. 9b shows a state in which the storage rack 20 is released from the fixation at a predetermined height position.
First, as shown in the left view of fig. 9a, when the storage rack 20 is moved to a predetermined height position, the first convex portion 211 of the rib 21 engages with the first concave portion 311 of the rail groove 31, and the second convex portion 212 of the rib 21 engages with the second concave portion 312 of the rail groove 31. Thereby, the storage rack 20 is supported by the rail groove 31 of the storage rack height position adjusting section 30 and fixed at a predetermined height position.
At this time, as shown in the lower right diagram of fig. 9a, a gap S1 is provided between the region 21B1 of the rear wall 21B of the rib 21, which is opposite to the first convex portion 211, and the second side wall 31S2 of the rail groove 31. Referring to the upper right view of fig. 9a, a gap S2 is provided between the region 21F1 of the front wall 21F of the rib 21, which is opposite to the second convex portion 212, and the first side wall 31S1 of the rail groove 31.
In this state, when the storage rack 20 is inclined as shown in the left view of fig. 9b, for example, the rear side is raised more than the front side, since there are gaps S1 and S2 between the rib 21 and the rail groove 31, the upper side of the rib 21 moves forward, i.e., to the right of the figure, with reference to the upper right view of fig. 9b, while the lower side of the rib 21 moves rearward, i.e., to the left of the figure, with reference to the lower right view of fig. 9 b. Thereby, the engagement between the first convex portion 211 and the first concave portion 311 is released, and the engagement between the second convex portion 212 and the second concave portion 312 is released. This releases the fixation of the storage rack 20.
The housing rack 20 after the release of the fixation returns to the state of being movable up and down again. Next, the storage rack 20 moves up and down, and the first protruding portion 211 engages with the other first recessed portion 311 of the rail groove 31 and the second protruding portion 211 engages with the other second recessed portion 312 of the rail groove 31, whereby the storage rack 20 can be fixed at different height positions.
According to the present embodiment, since the height position of the storage rack 20 can be adjusted by the fitting structure of the rib 21 and the rail groove 31, the structure is simple, and the cost can be reduced. Further, since the fixation of the storage rack 20 can be released only by tilting the storage rack 20, the height adjustment of the storage rack 20 can be easily performed.
However, the manner of releasing the fixation of the storage rack 20 is not limited to that shown in fig. 9. For example, if the first protruding portion 211 is provided on the upper side of the rib 21 and the second protruding portion 212 is provided on the lower side of the rib 21, the fixing of the storage rack 20 can be released such that the rear side of the storage rack 20 is lowered than the front side, that is, the storage rack 20 is inclined in the opposite direction to fig. 9 b. The fixation of the storage rack 20 may be released in another way.
Next, the operation of the rotating body 22 and the lock lever 23 provided in the storage rack 20 will be described with reference to fig. 10. Here, fig. 10a is a diagram illustrating the actions of the rotating body 22 and the lock lever 23 when the storage rack 20 is lifted. Fig. 10b is a view illustrating the actions of the rotating body 22 and the lock lever 23 when the storage rack 20 is lowered.
First, when the storage rack 20 is lifted, the pinion 222 engaged with the rack of the storage rack height adjusting section 30 rotates. In conjunction with this, the claw 224 coupled to the pinion gear 222 via the base 221 rotates in the arrow direction shown in fig. 10 a. At this time, the inclined surface 224S of the claw 224 collides with one surface 233S of the collision convex portion 233 constituting the lock lever 23.
As described above, one surface 233S is inclined in correspondence with the inclined surface 224S. The other end 232 of the collision convex portion 233 including the lock lever 23 is rotatable around the one end 231. Thus, after the inclined surface 224S collides with the one surface 233S, the inclined surface 224S slides on the one surface 233S while pushing up the other end side 232 of the lock lever 23 by the collision pressure of the inclined surface 224S.
Then, the rotation operation of the claw 224 shown in fig. 10a is not stopped by the lock lever 23. Thus, the claw 224 can continue to rotate in this manner, and thus the operation of the storage rack 20 is not hindered. In addition, the lifting operation of the storage rack 20 is assisted by the rotation of the pinion gear 222 of the rotating body 22 engaged with the rack 32 of the storage rack height position adjusting section 30.
In contrast, when the storage rack 20 is lowered, the pinion gear 222 and the claw 224 rotate in the arrow direction shown in fig. 10 b. At this time, the vertical surface 224V of the claw 224 collides with the aforementioned one surface 233S together with the other surface 233V of the collision convex portion 233 constituting the lock lever 23.
As described above, the vertical surface 224V of the claw 224 is erected from the outer peripheral surface of the annular portion 223. Further, the other surface 233V of the lock lever 23 is disposed vertically downward from the bottom of the lock lever 23. Thus, the moving direction of the vertical surface 224V that collides with the other surface 233V is substantially orthogonal to the other surface 233V. Thus, the perpendicular surface 224V and the other surface 233V physically interfere with each other. As a result, the other surface 233V resists further rotation of the vertical surface 224V. Accordingly, the rotation of the pinion gear 222 is stopped, and further lowering of the storage rack 20 is stopped.
In this way, the descent of the storage rack 20 is stopped by the action of the locking lever 23. Thus, even if the rib 21 of the storage rack 20 is not sufficiently engaged with the rail groove 31 of the storage rack height adjusting section 30, the claw 224 and the lock lever 23 act to prevent the storage rack 20 from falling down or falling off from the rail groove 31.
When the height position of the storage rack 20 is intentionally lowered, the other end 232 of the lock lever 23 is lifted. Thereby, the collision of the claw 224 with the collision convex portion 233 is avoided, and the rotation of the claw 224 shown in fig. 10b is not hindered. As a result, the pinion gear 222 can rotate while engaging with the rack 32, and allows the storage rack 20 to descend.
The embodiments according to the present invention are described in detail above. However, the foregoing description is given for the purpose of promoting an understanding of the invention and is not intended to limit the scope of the invention. The present invention can cover modifications and improvements without departing from the spirit. Furthermore, the invention encompasses equivalents thereof.
