(Refrigerator according to one embodiment of the present invention)

1 : is a perspective view which shows the inside of the refrigerator 2 which concerns on one Embodiment of this invention. FIG. 2 is a perspective view showing a state in which the door member in FIG. 1 is removed. FIG. 3 is an enlarged perspective view showing the vegetable storage container and the door member shown in FIG. 2 . FIG. 4 is an enlarged perspective view showing a region indicated by arrow A in FIG. 3 . FIG. 5 is an enlarged perspective view showing a region indicated by arrow B in FIG. 3 .

In FIGS. 1 and 2 , the door for opening and closing the front surface of the refrigerator 2 is removed so that the state of the inside of the refrigerator 4 can be checked. A refrigerating container 6 and a water supply tank 8 are arranged side by side from the center of the refrigerator 4 slightly downward. Fresh food such as meat and fish is accommodated in the refrigerated container 6, which is usually kept at a temperature slightly lower than that of the refrigerating compartment. Water for ice making to be supplied to the ice making vessel is stored in the water supply tank 8 . The water in the water supply tank 8 is sucked up by a pump to be supplied to the ice making vessel.

On the lower sides of the refrigerating container 6 and the water supply tank 8, the vegetable storage container 10 is arranged with a partition 30 (refer to FIG. 3) interposed therebetween. The vegetable storage container 10 is a pull-out container suitable for storing vegetables, fruits, and the like. The temperature in the vegetable storage container 10 is kept slightly higher than that of the refrigerating compartment, and the humidity thereof is also kept slightly higher than that of the refrigerating compartment. The vegetable storage container 10 is composed of a bottom plate, a front plate surrounding the bottom plate, a rear plate, and plates on both sides, and an upper surface thereof is opened. When storing items in the vegetable storage container 10, the door of the refrigerator 2 is opened, the vegetable storage container 10 in the storage position in the inner rear of the refrigerator 4 is pulled out to the front, and the storage items are accessed from the upper opening. After the storage and retrieval of the stored items is completed, the vegetable storage container 10 is inserted back into the rear storage position, and the door of the refrigerator 2 is closed, so that the original state can be returned.

As shown in FIGS. 2 and 3 , there is a space S between the upper part 10A of the front surface of the vegetable storage container 10 in the storage area and the lower surface of the partition plate 30 . Although shown in the removed state in FIGS. 2 and 3 , the swing door member 20 for opening and closing the space S is provided there.

As shown in FIG. 5, the cylindrical shaft member 32 is formed in the right side of the front surface of the partition 30 fixed to the refrigerator main body. Similarly, a cylindrical shaft member 32 is also formed on the left side of the front surface of the separator 30 .

On the other hand, in the door member 20 , as shown in FIG. 4 , on the right side of the door main body 22 extending left and right to cover the space S, a door socket 24 is formed, and the door socket 24 has a hole 24A having a hole for A circular cross-section into which the shaft member 32 is inserted; and a peripheral portion 24B surrounding the hole portion 24A. Similarly, a door socket 24 having a hole portion 24A and a peripheral portion 24B is also formed on the left side of the door main body 22 .

The shaft member 32 extends substantially horizontally in the left-right direction, and the door member 20 is rotatably movable along the extending direction of the door main body 22 with a horizontal line extending substantially to the left and right as a rotation center. The peripheral portion 24B has an arc-shaped outer surface when viewed in the direction of the rotation axis, and a part of the peripheral portion 24B is provided with the notch portion 26 . The cutout portion 26 has a width dimension through which the shaft member 32 can pass. Thus, the peripheral portion 24B having the cutout portion 26 has a substantially U-shaped or substantially C-shaped shape when viewed from the direction of the rotation axis. In the case of such a configuration, when the door member 20 is rotated and moved, there is a risk that the shaft member 32 passes through the cutout portion 26 to disengage the door socket portion 24 from the shaft member 32 .

However, as shown in FIG. 5 , at the partition plate 30 , a restraining member 34 having an arc-shaped inner surface is formed on the outer side (when viewed from the direction of the rotation axis) of the shaft member 32 . The restraining member 34 is disposed so as to surround the arc-shaped outer surface of the peripheral portion 24B that surrounds the hole portion 24A into which the shaft member 32 is inserted. With the restraining member 34 thus arranged, the door socket portion 24 can be rotated around the shaft member 32 , but the movement in the direction away from the shaft member 32 can be restrained. In this way, within the range in which the restraining member 34 surrounds the outer side of the peripheral portion 24B, there is no risk that the door socket portion 24 is detached from the shaft member 32, and the door member 20 can be reliably rotated. The restricting member 34 surrounding the peripheral portion 24B does not exist over the entire circumference of the shaft member 32 , but there is a rotation area in which the peripheral portion 24B is not surrounded by the restricting member 34 . This will be described in further detail.

Moreover, as shown in FIG. 4, the handle part 28 is extended at the left and right end parts of the door member 20, and the front end part of the handle part 28 is formed with the sliding part 28A which contacts the cam surface 12 provided in the vegetable storage which will be described later. on the container 10.

(Rotation mechanism of door parts)

6A is a side sectional view schematically showing a state where the vegetable storage container 10 is in the storage position and the door member 20 is in the closed rotation position. 6B is a side cross-sectional view schematically showing a state in which the vegetable storage container 10 is pulled out to the front side from the state shown in FIG. 6A and the door member 20 is rotationally moved in the release direction. 6C is a side cross-sectional view schematically showing a state in which the vegetable storage container 10 is further pulled out to the front side from the state shown in FIG. 6B and the door member 20 is further rotated and moved in the release direction.

6A to 6C , and any of FIGS. 7 , 8A and 8B described later are side sectional views of the side of the left side of the vegetable storage container 10 viewed from the inside of the vegetable storage container 10 , showing a view from the inside of the vegetable storage container 10 . The side surface of the translucent vegetable storage container 10 sees through the cam surface 12 , the handle portion 28 , and the sliding portion 28A. In addition, (b) of each figure shows the periphery of the door socket part 24 shown in (a) in an enlarged scale.

The cam surface 12 provided in the outer surface of the both side boards of the vegetable storage container 10 has the curved surface part 12A formed so that the height may become high as it advances to the back, and the flat surface part 12B which is substantially horizontal. As shown in FIG. 6A , in a state where the vegetable storage container 10 is at the storage position, the door member 20 is at the rotation position of the substantially lowest point. At this time, the lower part 22A of the door main body 22 is arranged so as to be close to the upper part 10A of the front surface of the vegetable storage container 10 . In this way, the space S on the upper side of the front surface of the vegetable storage container 10 can be closed. Not only the lower part 22A of the door body 22 is close to the upper part 10A of the front surface of the vegetable storage container 10 , but also the lower part 22A of the door body 22 can be brought into contact with the upper part 10A of the front surface of the vegetable storage container 10 . At this time, the sliding portion 28A of the door member 20 is in contact with the lower region of the curved portion 12A of the cam surface 12 .

When the vegetable storage container 10 is pulled out from such a state to the front side, the sliding portion 28A slides upward along the cam surface 12, and the door member 20 rotates to the front side. That is, the lower part 22A of the door member 20 rotates so that it may move upward and forward. In this way, it is possible to further open the space S above the front surface of the vegetable storage container 10 . Such a rotational direction of the door member 20 is referred to as an opening direction. In addition, the reverse rotation direction of this rotation direction is called a closing direction.

6B shows a state where the sliding portion 28A is in contact with the upper region of the curved portion 12A of the cam surface 12 , and FIG. 6C shows a state where the sliding portion 28A is in contact with the flat surface portion 12B of the cam surface 12 . When the sliding portion 28A is in contact with the curved portion 12A of the cam surface 12, the door member 20 is rotated in the opening direction as the vegetable storage container 10 is pulled out to the front side. On the other hand, after the sliding portion 28A reaches the flat portion of the cam surface 12, even if the vegetable storage container 10 is pulled out further to the front side, the door member 20 does not rotate further, so that the rotating position can be maintained.

In any of the states shown in FIGS. 6A to 6C , as shown in (b), at least a part of the outer surface of the peripheral portion 24B other than the cutout portion 26 is surrounded by the inner surface of the restraining member 34 . In particular, at least a part of the outer surface of the region on the 180-degree opposite side of the cutout portion 26 is surrounded by the inner surface of the restraining member 34 . Therefore, the movement of the door socket portion 24 in the direction away from the shaft member 32 on the side opposite to the cutout portion 26 is restrained by the restraining member 34 . In this way, there is no risk of the door socket 24 being detached from the shaft member 32, and the door member 20 can be rotated reliably.

In this way, when the vegetable storage container 10 is pulled out, the door member 20 can be rotated and moved in the opening direction from the closed rotation position. Conversely, when the vegetable storage container 10 pulled out to the front is stuffed back to the rear storage position, the sliding portion 28A slides on the cam surface 12 by the gravity acting on the door member 20, and the door member 20 rotates in the closing direction. . When the vegetable storage container 10 returns to the rear storage position, the door member 20 returns to the original closed rotation position, and the space S on the upper front surface of the vegetable storage container 10 can be closed by the door member 20 .

7 is a side view schematically showing a state in which the door member 20 interferes with the upper member and restrains the further rotational movement of the door member in the release direction. FIG. 7 shows a state in which the sliding portion 28A of the door member 20 is further rotated and moved in the opening direction than the rotational position at which the sliding portion 28A of the door member 20 is in contact with the flat surface portion 12B of the cam surface 12 of the vegetable storage container 10 . In this case, the lower part of the refrigerator container 6 and the water supply tank 8 arranged on the upper side of the vegetable storage container 10 are in contact with the door body 22 of the door member 20 via the partition 30 and cannot be rotated further in the opening direction. In this rotation position, the movement of the door socket portion 24 in the direction away from the shaft member 32 on the opposite side to the cutout portion 26 is restricted by the restricting member 34 . In this way, the movement of the door socket portion 24 in the direction away from the shaft member 32 is regulated by the restraining member 34 when the rotational movement is within the predetermined rotational angle from the closed rotational position. Preferably, such a designated rotation angle is taken to be 70 to 80 degrees or more.

8A is a side view schematically showing a state in which the door member 20 is rotationally moved from the closed rotational position by more than a specified rotational angle and reaches the detachable rotational position. 8B is a side view schematically showing a state in which the door member 20 is removed from the shaft member 32 in the attachment and detachment rotation position. The refrigerator container 6 and the water supply tank 8 arranged on the upper side of the vegetable storage container 10 can be removed from the refrigerator. When the refrigerating container 6 and the water supply tank 8 are removed, the door member 20 can be rotated and moved in the release rotation direction further than the predetermined rotation angle.

As shown in FIG. 8A , when the door member 20 is rotationally moved to the detachable rotational position, the outer surface of the area on the opposite side of the cutout portion 26 of the peripheral portion 24B by 180 degrees is not surrounded by the inner surface of the restraining member 34 . Therefore, as shown by the arrow in FIG. 8A , the socket portion 24 can be pulled out so that the shaft member 32 is passed through the cutout portion 26 without being restrained by the restraining member 34 . Since the door member 20 is pulled out substantially horizontally toward the front side of the refrigerator 2, the door member 20 can be easily removed without interfering with other members of the refrigerator 2. The state after being pulled out is shown in FIG. 8B . In this way, only the door member 20 can be removed for easy cleaning. Further, after cleaning, the door socket portion 24 of the door member 20 can be attached to the shaft member 32 in the reverse order of the order in which the door member 20 is pulled out.

(General record)

In the above-described embodiment, the storage area is provided in the vegetable storage container 10, but it is not limited to this. The storage area can be provided in any other container arranged in the refrigerator 4 . In addition, it is also possible that the storage area may not be in the container, but is directly provided in the inner box of the refrigerator, and the door member 20 is a door for opening and closing the front surface thereof.

In the above-described embodiment, the space on the upper side of the front surface of the vegetable storage container 10 is opened and closed by the door member 20, but the present invention is not limited to this. For example, the entire front surface of the vegetable storage container 10 is open, and the door member 20 may be used to open and close the entire front surface, or the door member 20 may be used to open and close spaces provided in other areas of the front surface. . Along with this, the rotation axis of the door member 20 may not be limited to a substantially left-right direction, but an up-down direction or an inclined direction.

In the above-described embodiment, when the vegetable storage container 10 is pulled out, the door member 20 is moved in the opening direction by the cam mechanism, but the present invention is not limited to this. It is also possible to pull out the vegetable storage container 10 without the cam mechanism and to bring the lower part of the door member 20 into contact with the upper surface of the side wall of the vegetable storage container 10 .

As described above, the refrigerator 2 according to the present invention includes: the door member 20 for opening and closing at least a part of the front surface of the storage area in the refrigerator 4; the shaft member 32 serving as the rotation shaft of the door member 20; 24, which is formed on the door member 20 and has a peripheral portion 24B that surrounds a hole portion 24A into which the shaft member 32 is inserted; a cutout portion 26 that is provided on a portion of the peripheral portion 24B and is sized to allow the shaft member 32 to pass therethrough; And a restraining member 34 , which surrounds the outer surface of the peripheral portion 24B, enables the socket portion 24 to rotate about the shaft member 32 but restrains the movement of the socket portion 24 in a direction away from the shaft member 32 .

In this case, when the door member 20 is rotationally moved from the closed rotational position that closes at least a part of the front surface of the storage area to the opening direction that opens the front surface of the storage area, as shown in FIGS. 6A to 6C and FIG. 7 , When the rotation angle is within the specified rotation angle, the movement of the door socket portion 24 in the direction away from the shaft member 32 is restricted by the restriction member 34 . On the other hand, as shown in FIGS. 8A and 8B , when the door member 20 is rotated and moved more than a predetermined rotation angle, the door member 20 is pulled down so that the shaft member 32 passes through the cutout portion 26 without being restrained by the restraint member 34 . Thereby, the door member 20 can be removed from the shaft member 32 , and the removed door member 20 can be attached to the shaft member 32 again. In this way, the door member 20 can be easily cleaned and returned to its original position.

As described above, through the cutout portion 26 and the restraining member 34, the door member 20 can be easily attached and detached without adding a special member or bending the door member 20. Therefore, it is possible to provide the refrigerator 2 in which the door member 20 for opening and closing the front surface of the storage area can be easily attached and detached while having a simple structure.

In particular, when the storage area is provided in the pull-out container 10 that can move back and forth as in the above-described embodiment, in the closed rotation position, the lower part 22A of the door member 20 is located in front of the container 10 in the storage position. The upper portion 10A of the surface approaches or touches. In addition, the opening direction is a direction in which the lower part of the door member 20 rotates so as to move upward and front. In order to realize this, the rotation shaft of the door member 20 extends substantially in the left-right direction, and the shaft member 32 and the restraining member 34 are fixed to the refrigerator main body side (eg, the partition plate 30 ).

In this way, when the pull-out container 10 is in the storage position, the space on the upper side of the front surface of the container 10 can be closed by the door member 20, and when the container 10 is pulled forward, the door member 20 can be opened to the Since the direction is rotated, the container 10 can be easily pulled out without interfering with the door member 20 .

Further, as shown in FIGS. 6A to 6C , when the container 10 is provided with the cam surface 12 and the door member 20 is provided with the sliding portion 28A in contact with the cam surface 12 , when the container 10 is moved from the storage position to the When the sliding portion 28A is pulled forward, the sliding portion 28A slides on the cam surface 12 to rotate and move the door member 20 in the opening direction.

In this way, when the container 10 is pulled forward from the storage position by the cam surface 12 and the sliding portion 28A, the door member 20 is rotated and moved in the opening direction. In this way, the user can rotate the door member 20 to open the container 10 simply by pulling out the container 10, so that the stored items can be easily accessed.

Further, as shown in FIGS. 6A to 6C , when the sliding portion 28A slides on the cam surface 12 , the door member 20 is rotationally moved within a range of a specified rotational angle from the closed rotational position. Therefore, when the container 10 is pulled forward to rotate and move the door member 20 in the opening direction, there is no risk that the door member 20 is detached from the shaft member 32 , so that the door member 20 can be reliably opened and closed for the opening and closing of the container 10 . Access to storage.

In addition, as shown in FIG. 7 , the door member 20 cannot be rotationally moved from the closed rotational position by more than a specified rotational movement by interfering with removable components (eg, the refrigerating container 6 , the water supply tank 8 ) disposed above the container 10 . angle. That is, the container 10 is provided with the cam surface 12 and the door member 20 is provided with a sliding portion 28A in contact with the cam surface 12. When the container 10 is pulled forward from the storage position, the sliding portion 28A slides on the cam surface 12. By sliding up, the door member 20 is rotated and moved in the opening direction within the range of the specified rotation angle from the closed rotation position.

In this way, since the door member 20 cannot be rotated to the removable position by the members (for example, the refrigerating container 6 and the water supply tank 8) arranged above the container 10, the door member 20 can be reliably opened and closed during normal use.
