Description

refrigerator

This technology is related to refrigerators. In particular, it relates to movement of storage shelves.

Refrigerators can store and cool stored items such as food. In order to increase the degree of freedom in storability, conventional refrigerators are provided with a plurality of storage shelves and support members that support the storage shelves at a plurality of positions on the side surfaces of the storage compartment. By configuring the storage room to have a plurality of storage shelves and supporting members, it is possible to change the position at which the storage shelves are supported according to the height of the items to be stored.

Here, when changing the position of the storage shelf, the storage shelf had to be removed once, and every time the position of the storage shelf was changed, the stored items had to be taken out. Therefore, a refrigerator has been proposed that has a storage shelf provided with means for adjusting the position of the storage shelf (see, for example, Patent Document 1).

JP-A-2001-050648

However, the refrigerator of Patent Document 1 described above has a means for adjusting the position in the vertical direction in the storage shelf main body. Therefore, the moving mechanism for moving the storage shelf is exposed inside the storage compartment. Therefore, the configuration of the storage shelf becomes complicated, and the degree of freedom in the shape of the storage shelf is reduced. In addition, since the mechanism portion for adjusting the vertical position is not configured to transmit light, the area of the shadow in the storage chamber becomes large. As a result, the inside of the storage compartment becomes dark and the visibility of the stored items becomes poor. Then, even if the user tries to see the stored items through the face of the storage shelf, the mechanical portion shields the stored items so that the stored items cannot be seen.

Therefore, an object is to obtain a refrigerator in which storage shelves can be moved without exposing the moving mechanism inside the storage compartment.

In order to solve the above problem, the refrigerator according to the present disclosure has a main body having a storage compartment, a storage shelf that partitions the storage compartment in the height direction, and at least a portion of which is embedded in a recessed wall of a side wall of the storage compartment in the width direction. and a pair of storage shelf support devices for supporting the storage shelf, the storage shelf support device comprising: a rail portion having a storage shelf support portion for supporting the storage shelf; and a moving mechanism for moving the rail portion in the height direction. , a rail holder that is attached to the side wall in the width direction of the storage room and holds the rail part so that it can move in the height direction; and an embedded rail portion holding member.

According to the disclosed refrigerator, in the rail component for moving the position of the storage shelf in the vertical direction, the rail portion holding member for storing the moving mechanism is embedded and attached to the recessed portion of the wall of the storage compartment. For this reason, it is possible to adopt a configuration in which the moving mechanism is not exposed to the storage chamber.

FIG. 5 is an exploded view explaining the configuration of the rail component 2 according to the first embodiment. 6 is a view of the rail component 2 according to Embodiment 1 as seen from inside the refrigerator compartment 101. As shown in FIG. Furthermore, FIG. 7 is a diagram illustrating the internal mechanism of the rail component 2 according to the first embodiment.

Here, FIG. 6 shows the rail component 2 installed on the left side wall of the refrigerator compartment 101 . As shown in FIGS. 5 and 6 , the rail component 2 of Embodiment 1 has a rail portion 3 , a rail portion lowering lock lever 6 , an adjustment lever 7 , a rail height scale 8 and a rail holder 9 .

The rail portion 3 has a storage shelf support portion 4 and a storage shelf holding portion 5. The rail part 3 holds the storage shelf 1 inserted between the storage shelf supporting part 4 and the storage shelf pressing part 5 which are rails. The storage shelf support part 4 guides and supports the storage shelf 1 on the lower side. Further, the storage shelf pressing part 5 guides and presses the storage shelf 1 from above. Here, the rail component 2 of Embodiment 1 is held by the rail holder 9 by the user sliding the adjustment lever 7 in the front-rear direction of the refrigerator compartment 101 in accordance with the rail height scale 8 . It has a structure that can move the rail portion 3 in the vertical direction. The adjustment lever 7 is a lever for the user to adjust the position by moving the rail portion 3 . The moving operation of the rail portion 3 and the like will be described later. Further, the rail lowering lock lever 6 is operated by the user to fix or release the position of the rail 3 so that the rail lowering lock gear 13, which will be described later, is operated to prevent the rail 3 from lowering. is the lever of The locking operation of the rail portion 3 will be described later.

5 and 7, the rail component 2 includes a transmission belt 10, a vertical operation gear 11, a plurality of transmission gears 12, and a rail lowering lock corresponding to the rail portion 3 with a rail holder 9 interposed therebetween. It has a gear 13 and a rail rear cover 14 . The rail rear surface cover 14 covers and houses the transmission belt 10, the vertical operation gear 11, the plurality of transmission gears 12, and the rail downward lock gear 13. As shown in FIG. The rail rear cover 14 is attached substantially parallel to a rail holding member 15 to be described later, and is in contact with or in the vicinity of the transmission belt 10 , the vertical operation gear 11 and the transmission gear 12 . The rail rear cover 14 prevents the transmission belt 10, the vertical movement gear 11 and the transmission gear 12 from coming off from the rail holding member 15 when they are operated.

The transmission belt 10 , the vertical movement gear 11 and the plurality of transmission gears 12 constitute a moving mechanism 50 . The transmission belt 10 is engaged with a part of the adjusting lever 7 and moves in conjunction with the sliding movement of the adjusting lever 7 . Also, the transmission gear 12 is in contact with the transmission belt 10 . The transmission gear 12 converts movement of the transmission belt 10 into rotational motion. The vertical movement gear 11 is in contact with the transmission gear 12 . The vertical movement gear 11 converts the rotational motion of the transmission gear 12 into a vertical movement motion. A part of the vertical operation gear 11 is inserted through an opening 9A provided in the rail holder 9 toward the refrigerating compartment 101, and as will be described later, a support recess 4A formed inside the storage shelf support portion 4 in the rail portion 3. (See FIG. 8). Here, the moving mechanism 50 of Embodiment 1 arranges a plurality of transmission gears 12 between the vertical movement gear 11 and the transmission belt 10 . Among the plurality of transmission gears 12, the diameter of the transmission gear 12 arranged on the vertical operation gear 11 side is smaller than the diameter of the transmission gear 12 on the transmission belt 10 side. Therefore, the amount of lever movement by which the user slides the adjustment lever 7 is larger than the amount of vertical movement of the rail portion 3 in the vertical direction. Therefore, even when food is stored in the storage shelf 1, the user can move the adjustment lever 7 with a small force.

The rail lowering lock gear 13 is a lock mechanism that fixes the position of the storage shelf 1 so that it does not lower due to its own weight and the load of stored food. When the rail portion 3 is unlocked by operating the rail portion descending lock lever 6, the rail descending lock gear 13 reduces the resistance to the movement of the transmission belt 10 and allows the rail portion 3 to move downward. .

FIG. 8 is a diagram for explaining how the rail component 2 is attached to the main body of the refrigerator 100 according to Embodiment 1. FIG.

The rail holder 9 becomes a panel attached to the wall surface of the refrigerator compartment 101 . Thus, the rail component 2 is fixed and attached to the inner wall 112 of the refrigerator compartment 101 . Here, in the rail component member 2 of Embodiment 1, the outer circumference of the rail holder 9 is larger than the outer circumference of the rail portion holding member 15 . Therefore, the rail portion holding member 15 is covered with the rail holder 9 . Therefore, the rail portion holding member 15 is not exposed to the refrigerator compartment 101 when the rail component member 2 is viewed from inside the refrigerator compartment 101 and is invisible to the user of the refrigerator 100 .

Further, since the rail holder 9 allows the vertical movement gear 11 to move in the vertical direction, as described above, the slit-shaped opening 9A corresponding to the movement length is formed along the direction in which the vertical movement gear 11 moves. have. The vertical movement gear 11 is fitted in the support recess 4A formed inside the storage shelf support 4, as described above. The rail portion 3 of Embodiment 1 has a wall for hiding the opening 9A of the rail holder 9 from being seen from the refrigerator compartment 101 side, together with the storage shelf support portion 4 and the storage shelf pressing portion 5. FIG. The wall of the rail portion 3 has an upper end at a position where it can cover the opening 9A of the rail holder 9 when the rail portion 3 is at the lowest position of the movable range, and the rail portion 3 is at the highest position of the movable range. The lower end is at a position where it can cover the opening 9A of the rail holder 9 when in position. Therefore, the refrigerator 100 of Embodiment 1 can keep the design of the rail component 2 without showing the opening 9A of the rail holder 9 to the user. Furthermore, in the refrigerator 100, dirt can be prevented from entering the inside of the rail portion 3 through the opening 9A of the rail holder 9.

FIG. 9 is a diagram explaining the movement of the rail portion 3 according to Embodiment 1. FIG. 10A and 10B are diagrams for explaining the movement of the moving mechanism 50 according to the first embodiment. The operation of the rail component 2 according to the first embodiment will be described with reference to FIGS. 9 and 10. FIG. Here, the view shown on the left side of FIG. 9 is a view showing the appearance of the rail component 2 before the rail portion 3 is moved upward. 9 shows the appearance of the rail component 2 after the rail portion 3 has been moved upward. On the other hand, the drawing shown on the left side of FIG. 10 shows the state of the moving mechanism 50 before the rail portion 3 is moved upward. 10 shows the state of the moving mechanism 50 for the rail holder 9 after the rail portion 3 has been moved upward. Here, a case of moving the rail portion 3 upward will be described. As shown in FIG. 9, when the user moves the adjustment lever 7 toward the rear side of the refrigerator compartment 101, as shown in FIG. Moving. Further, the transmission gear 12 rotates according to the amount of movement of the transmission belt 10 and transmits the rotation to the vertical operation gear 11 .

In conjunction with the vertical movement gear 11, the rail portion 3 moves upward as shown in FIG.

FIG. 11 is a diagram showing the state of the rail lowering lock gear 13 when the rail portion 3 according to Embodiment 1 is moving upward. As shown in FIG. 9 described above, when the rail portion 3 is moved upward by the adjustment lever 7, as shown in FIG. move to

FIG. 12 is a diagram showing a state in which the rail portion 3 according to Embodiment 1 is locked at the uppermost stage. FIG. 13 is a diagram showing the state of the rail lowering lock gear 13 when the rail portion 3 according to Embodiment 1 is locked. When the user releases the adjustment lever 7, the transmission belt 10 tries to move in the direction of lowering the position of the rail portion 3 due to the weight of the storage shelf 1 and the weight of the food placed on the storage shelf 1. At this time, as shown in FIG. 12, when the rail lowering lock lever 6 is on the lock side, as shown in FIG. It functions as a stopper that prevents 3 from moving downward.

FIG. 14 is a diagram showing a state when the lock according to Embodiment 1 is released. As shown in FIG. 14 , when the user operates the rail descent lock lever 6 to the release side and the rail descent lock lever 6 is on the release side, the rail descent lock gear 13 moves the transmission belt 10 forward. It does not prevent the movement of the rail portion 3 in the lowering direction.

As described above, according to the refrigerator 100 of Embodiment 1, the housing portion of the rail component member 2 that allows the position of the storage shelf 1 to be moved up and down is placed in the wall recess formed in the inner wall 112 of the refrigerator compartment 101 . 112A. Therefore, the storage shelf 1 does not need to have the moving mechanism 50, and the flexibility of the configuration of the storage shelf 1 can be ensured. Further, the moving mechanism 50 and the like are embedded in the inner wall 112 and are not exposed inside the refrigerator compartment 101 . Therefore, in the refrigerator compartment 101, the light is not blocked by the moving mechanism 50 and the like, and the shadow of the refrigerator compartment 101 is reduced, so that the inside of the room can be illuminated. In addition, it becomes easier for the user to visually recognize the stored items. The rail component 2 of Embodiment 1 is attached to the side wall of the refrigerator compartment 101 so that the rail holder 9 covers the moving mechanism 50 of the rail component 2 and the like. Therefore, refrigerator 100 of Embodiment 1 can maintain the design of refrigerating compartment 101 .

Further, the moving mechanism 50 of the rail component 2 has a structure in which the lever movement amount of the adjustment lever 7 transmitted to the moving mechanism 50 is larger than the vertical movement amount for moving the rail portion 3 in the vertical direction. Therefore, even when stored items are placed on the storage shelf 1, the user can slide the adjustment lever 7 with a small force. Moreover, the user can easily adjust the position of the rail portion 3 . Moreover, since the adjustment lever 7 can be slid in the front-rear direction of the refrigerator 100, it is easy for the user to operate.

Further, the rail component 2 of Embodiment 1 has a rail lowering lock lever 6 and a rail lowering lock gear 13 as a lock mechanism. Therefore, it is possible to prevent the storage shelf 1 from descending due to the weight of the storage shelf 1 and the weight of the food stored in the storage shelf 1 .

Further, the rail portion 3 of Embodiment 1 has a wall for hiding the opening 9A of the rail holder 9 from being seen from the refrigerator compartment 101 side. Therefore, the refrigerator compartment 101 can maintain its design. In addition, dirt from refrigerator compartment 101 can be prevented from adhering to moving mechanism 50 .

Embodiment 2.
FIG. 15 is a diagram showing the installation relationship between the rail portion 3 and the storage shelf 1 in the rail component member 2 according to the second embodiment. 16A and 16B are diagrams for explaining inclination of the storage shelf 1 when the positions of the rail portions 3 in the rail component 2 according to the second embodiment are different in the vertical direction. Refrigerator 100 of the second embodiment has the same configuration as that of the first embodiment. Therefore, the rail component members 2 are attached to the left and right inner walls 112 of the refrigerator compartment 101, respectively.

The user can operate the rail constituent members 2 attached to the inner walls 112 of the refrigerator compartment 101 respectively. And each rail part 3 can adjust a position of the up-down direction independently. Therefore, there may be a difference in the height of each rail portion 3 . When the height difference between the rail portions 3 of the rail component members 2 on both sides becomes large, the storage shelf 1 supported by the storage shelf support portion 4 of the two rail portions 3 and the food stored in the storage shelf 1 may tilt. have a nature.

Therefore, in order to make the difference in height equal to or less than a predetermined difference, in the rail holder 9 of the refrigerator 100 of the first embodiment, a rail height is provided in the vicinity of the adjustment lever 7 as a mark that indicates the lever movement amount of the adjustment lever 7 . A scale 8 is provided along the direction of movement of the adjustment lever 7. - 特許庁Thereby, the user can visually confirm the position of the rail portion 3 on the rail component member 2 on both side walls based on the scale of the rail height scale 8 . Therefore, the refrigerator 100 can recognize the height difference between the rail portions 3 in the rail component members 2 attached to the left and right side walls, and can keep the storage shelf 1 horizontal in the width direction.

Further, for example, when the user tries to adjust the position of the rail portion 3 or releases the locking mechanism of one of the rail component members 2, the heights of the left and right rail portions 3 do not match, and the storage shelf 1 does not fit. may be slanted. At this time, both ends of the storage shelf 1 contact between the storage shelf supporting portion 4 supporting the storage shelf 1 of the rail portion 3 and the storage shelf pressing portion 5 pressing the storage shelf 1 . Therefore, each rail portion 3 is vertically displaced, and even if the storage shelf 1 is tilted, it is not tilted at a predetermined angle θ or more.

Here, as shown in FIG. 15, the length of the gap formed between the end portion of the storage shelf 1 and the rail portion 3 is Δh. Further, W is the length of the protrusion of the storage shelf support portion 4 for supporting the storage shelf 1 of the rail portion 3 into the refrigerator compartment 101 . At this time, the relationship between the gap Δh, the width W, and the predetermined angle θ as shown in FIG. 16 can be expressed by the following equation (1).

tan θ=Δh/W
θ=tan ⁻¹ (Δh/W) (1)

As described above, according to the refrigerator 100 of Embodiment 2, the storage shelf supporting portion 4 and the storage shelf pressing portion 5 are configured to sandwich the storage shelf 1 therebetween. In the rail component members 2 attached to the left and right inner walls 112 of the refrigerator compartment 101, when the storage shelf 1 is tilted by a predetermined angle θ due to the difference in height of the rail portion 3, the storage shelf 1 is stored with the storage shelf support portion 4. It is made to be caught by the shelf pressing part 5. - 特許庁Therefore, the tilt of the storage shelf 1 can be suppressed, and the height difference between the rail portions 3 of the rail component members 2 attached to the left and right inner walls 112 can be suppressed to a predetermined difference or less.

In addition, the rail holder 9 of the rail component 2 has a rail height scale 8 along the movement direction of the adjustment lever 7. Therefore, the user can visually confirm the position of the rail portion 3 on both side surfaces based on the scale of the rail height scale 8 .

Embodiment 3.

Also, FIG. 18 is a diagram for explaining how the rail-constituting member 2 is attached when the rail-constituting member 2 is viewed from the WW section shown in FIG. The rail rear cover 14 is attached so as to be sandwiched between the rail holder 9 and the rail holding member 15 . Similarly to Embodiment 1, the rail component 2 is attached by fitting and burying the rail portion holding member 15 in the wall recess 112A formed in the inner wall 112 of the refrigerator compartment 101 . Then, the rail holder 9 is assembled to the rail portion holding member 15 . Here, the rail holder 9 is attached to the rail portion holding member 15 with the fixing screws 16 . Therefore, the rail portion holding member 15 has a screw hole 17 into which the fixing screw 16 is inserted. The screw hole 17 is provided in a range covered by the rail portion 3 in the rail portion holding member 15 . Therefore, the fixing screw 16 is attached at a position that cannot be seen from inside the refrigerator compartment 101 . When the rail holder 9 is attached to the rail portion holding member 15 with the fixing screw 16, the screw hole 17 is such that the screw head of the fixing screw 16 is inserted into the screw mounting concave portion 19 formed in the rail holder 9. in a position to fit. Therefore, the screw head of the fixing screw 16 does not protrude from the wall surface of the rail holder 9 on the refrigerating compartment 101 side and does not interfere with the vertical movement of the rail portion 3 .

In addition, the rail holding member 15 and the rail holder 9 are fixed in positional relationship when the seat surface 18 of the fixing screw 16 comes into contact with the bottom of the screw mounting recess 19 of the rail holder 9 . At this time, the shape is partially relieved so that the wall of the rail portion 3 does not hang over the fixing screw 16 .

As described above, according to the refrigerator 100 of Embodiment 3, the rail component member 2 is embedded in the wall recess 112A formed in the inner wall 112 of the refrigerator compartment 101 by fitting the rail portion holding member 15 therein. 100 is attached. Therefore, in refrigerator 100 of the second embodiment, rail component 2 including rail portion holding member 15 can be easily attached and detached from refrigerating compartment 101 . Therefore, the productivity and serviceability of refrigerator 100 can be improved. Moreover, since the fixing screw 16 is attached at a position not visible from the refrigerator compartment 101, the design can be maintained.
