1. Field of the Invention
The present invention relates to a refrigerator, and, more particularly, to a structure of a storage container equipped in a refrigerator which is capable of increasing an opened degree of the storage container obtained in accordance with an opening operation of the storage container.
2. Description of the Related Art
Generally, refrigerators store various foods at a low temperature in a fresh state in freezing and refrigerating compartments defined in a refrigerator body by circulating cold air in the freezing and refrigerating compartments. In the freezing compartment, food (such as meat or ice cream), to be maintained at a temperature not higher than a freezing temperature thereof, are stored. On the other hand, food (such as vegetables or beverages), to be maintained at a temperature slightly higher than the freezing temperature thereof, are stored in the refrigerating compartment.
With increased consumption of frozen foods and current busy life styles, people have an increased tendency to purchase large amounts of food at once so as to consume the food in small portions after storing the food. In pace with such a tendency, recently-developed refrigerators have a tendency to have an increased size. In accordance with this tendency, use of double swing door type refrigerators has increased. Also, the recent tendency of storage containers to be equipped in refrigerators has led to an increase in size of refrigerators.
Such storage containers equipped in refrigerators may be used for various purposes, and may be mounted to any portion of the refrigerator. However, such storage containers are mainly mounted to a lower portion of the refrigerator to store vegetables and fruits. Where a storage container, equipped in a large-size refrigerator, has a large size in accordance with the large size of the refrigerator, there is a problem in that the storage container may be incompletely opened even in a completely opened state of a door of the refrigerator because the door of the refrigerator interferes with the opening operation thereof. For this reason, although the storage container has a large size, there is a problem in that placing food, having a large size, into the storage container through an access opening provided at the storage container is difficult because the access opening of the storage container is narrow. Furthermore, removing food stored in a rear inner portion of the storage container is difficult.
Also, even where food is small, placing the small food into the storage container and taking the food out of the storage container may be difficult, even though the food has a small size.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below to explain the present invention by referring to the figures.
FIG. 1 is a perspective view illustrating a refrigerator 1 according to an embodiment of the present invention. The refrigerator 1 includes a rectangular box-shaped housing 10, and doors 20 to open and close openings defined at the housing 10, respectively. Refrigerating and freezing compartments are defined in the housing 10. Storage containers 12, 30 may be slidably mounted in the refrigerating and freezing compartments. A handle 21 is attached to each door 20 in order to assist a user to open and close the door 20.
In accordance with an embodiment of the present invention, the two storage containers 12 and 30 are mounted in a lower portion of the refrigerating compartment in a vertically arranged state. Of course, according to aspects of the invention, these storage containers may be mounted in the freezing compartment, and can be disposed elsewhere in the compartment. Further, additional or fewer containers could be used and could have other non-horizontal orientations.
The shown storage containers 12 and 30 have a rectangular box structure opened at the top thereof, but can also have other shapes. Each of the storage containers 12 and 30 has a width equal to or slightly smaller than the width of a corresponding portion of the housing 10 so that the storage containers 12 and 30 may be slidably fitted in the corresponding housing portion. In order to cover the opened top portion of each storage container 12 or 30, a cover is detachably mounted to the storage container 12 or 30. Where the storage container 12 or 30 is covered by a shelf mounted to a portion of the housing 10, in which the storage container 12 or 30 is fitted, such a cover may be dispensed with.
In the shown double swing door type refrigerator 1 having a large size, freezing and refrigerating compartments thereof are defined in left and right portions of a refrigerator body 10, respectively. Such a refrigerator 1 includes a plurality of shelves 11 mounted in each compartment, and a plurality of shelves 22 mounted to each door. The refrigerator 1 according to the shown embodiment of the present invention is of such a double swing door type while having a large size. In FIG. 1, the shelves 11 are mounted in each compartment, and the shelves 22 are mounted to each door 20. However, the shelves 22 provided at the refrigerating compartment may interfere with opening operations of the storage containers 12 and 30 resulting in storage containers 12 and 30 being insufficiently opened unless the refrigerator 1 according to an aspect of the present invention further includes interference eliminators to eliminate such interference.
FIG. 2 is a sectional view illustrating closed states of the storage containers 12 and 30 which include such interference eliminators in accordance with the illustrated embodiment of the present invention. The upper storage container 12 is fitted in the housing 10 such that the upper storage container 12 is slidable along rails (not shown) respectively provided at opposite side walls of the housing 10. The lower storage container 30 (hereinafter “the storage container 30”) is fitted in the housing 10 beneath the upper storage container 12 in a manner similar to that of the upper storage container 12. In order to prevent vegetables or fruits stored therein from being dried, the storage container 30 is provided with a cover 31. The cover 31 is slidably arranged on the top of a box-shaped container body 33 included in the storage container 30. In order to guide the sliding movement of the cover 31, a guide member 32 is also mounted to the housing 10. The guide member 32 is slidably fitted in a groove 32 a formed at the cover 31.
The cover 31 has a length which is smaller than a length of the storage container 30. Accordingly, the cover 31 partially covers the top of the storage container 30 such that the cover 31 covers a front portion of the top of the storage container 30 without also covering a rear portion of the top of the storage container 30 in the closed state of the storage container 30. The cover 31 has such a length so as to provide a space to allow the cover 31 to move rearwardly along the storage container 30.
A first rack gear 31 a is provided at a lower end of the cover 31 contacting an upper end of the container body 33. A second rack gear 33 a is also provided at the upper end of the container body 33. A pinion 34 is rotatably mounted to the refrigerator body 10 between the lower end of the cover 31 and the upper end of the container body 33 such that the pinion 34 is engaged with both the first rack gear 31 a of the cover 31 and the rack gear 33 a of the container body 33. The second rack gear 33 a provided at the container body 33 extends rearwardly from substantially the middle portion of the container body 33 by a desired length along the upper end of the container body 33 such that a front end thereof is engaged with the pinion 34 in a closed state of the container body 33. On the other hand, the second rack gear 31 a provided at the cover 31 extends forwardly from a position, corresponding to the substantially middle portion of the container body 33 in the closed state of the container body 33, by a desired length along the lower end of the cover 31 such that a rear end thereof is engaged with the pinion 34 in the closed state of the container body 33. In the closed state of the container body 33, accordingly, the first and second rack gears 31 a and 33 a are not overlapped with each other, except for ends thereof which engage with the pinion 34.
The pinion 34 is rotatably mounted on a shaft (not shown) fixedly mounted to the refrigerator body 10. The pinion 34 is rotated in accordance with a forward or rearward movement of the second rack gear 33 a of the container body 33 to cause the first rack gear 31 a of the cover 31 to be moved in a direction opposite to the movement direction of the second rack gear 33 a, as shown in FIGS. 2 and 3. For example, when the user draws the storage container 30 forward from an initial position in which the storage container 30 is in the closed state as shown in FIG. 2, the first rack gear 31 a is moved in a direction indicated by the arrow in FIG. 3 and the second rack gear 33 a is moved in a direction which is opposite to the direction of the area in FIG. 3. As a result, the pinion 34 is rotated in a clockwise direction, thereby causing the first rack gear 31 a of the cover 31 to be moved in a direction opposite to the movement direction of the second rack gear 33 a. Accordingly, the cover 31 is rearwardly moved into the interior of the refrigerator body 10, as shown in FIG. 3.
In order to provide a space to occupy the pinion 34, a first elongated groove 36 is formed at a lower end portion of the cover 31 corresponding in location to a location of the first rack gear 31 a. The first rack gear 31 a is formed at a surface of the first elongated groove 36. The first elongated groove 36 has, at front and rear ends thereof, curved surfaces 36 a serving as stoppers coming into contact with the pinion 34 in a rearwardly or forwardly moved state of the cover 31 to prevent the first rack gear 31 a from being disengaged from the pinion 34 due to a further rotation of the pinion 34.
FIG. 3 is a sectional view illustrating the opened state of the storage container according to the illustrated embodiment of the present invention. FIG. 3 shows that the upper storage container 12 is arranged over the storage container 30, and the cover 31 is in a state of being moved rearward in accordance with a rearward movement of the rack gear 31 and a guiding operation of the guide member 32 carried out when the storage container 33 is drawn forward to be opened.
In the illustrated embodiment of the present invention, a second elongated groove 37 is also formed at an upper end portion of the container body 33 corresponding to the rack gear 33 a, in order to provide the space to occupy the pinion 34 in cooperation with the elongated groove formed at the cover 31.
FIG. 4 is a perspective view illustrating a closed state of a storage container according to another embodiment of the present invention. In accordance with this embodiment of the present invention, the storage container 30′ includes a rectangular box-shaped container body 33′, and a humidity control member 35 arranged to cover a portion of a top of the container body 33′. The humidity control member 35 does not cover a front of the top of the container body 33′.
In order to cover the opened front top portion of the container body 33′, the storage container 30′ also includes a cover 31′. In accordance with this embodiment, a guide member to guide movement of the cover 31′ is not required, in contrast with the need for the guide member 32 of the above described embodiment in FIG. 2. The humidity control member 35, which covers the top portion of the container body 33′ not covered by the cover 31′, serves to control the humidity of the interior of the storage container 30′.
In order to move the cover 31′ in accordance with movement of the storage container 30′, first and second rack gears 31′a and 33′a, and a pinion 34′ are provided. The first rack gear 31′a is separably connected to the cover 31′ by way of a first connecting member 31′b while being slidably supported by an upper surface of the humidity control member 35. The second rack gear 33′a is separably connected to a rear end of the container body 33′ by means of a connecting member 33′b extending vertically through the humidity control member 35. The second rack gear 33′a is also slidably supported by the upper surface of the humidity control member 35. Each of the first and second connecting members 31′b and 33′b has a vertical pin structure so that the associated first and second rack gears 31′a or 33′a may be separated from the associated cover 31′ or container body 33′, respectively, by a simple vertical movement thereof, while being prevented from being separated from the associated cover 31′ or container body 33′, respectively, by a horizontal movement thereof.
The humidity control member 35 is fixedly mounted to a desired portion of the housing 10. In order to prevent the humidity control member 35 from interfering with the second connecting member 33′b, and thus, to allow the container body 33′ to move forwardly, an elongated slot 35 a is formed at the humidity control member 35 to extend in a longitudinal direction of the humidity control member 35. The second connecting member 33′b is received in the slot 35 a such that the second connecting member 33′b is movable along the slot 35 a. The pinion 34′ is rotatably mounted on the upper surface of the humidity control member 35 between the first and second rack gears 31′a and 33′a while being engaged with the first and second rack gears 31′a and 33′a.
FIG. 5 is a perspective view illustrating an opened state of the storage container according to the embodiment of FIG. 4. As shown in FIG. 5, the humidity control member 35 is arranged on the top of the container body 33′. It can also be seen that the second rack gear 33′a connected to the container body 33′, is laid on the humidity control member 35, and the first rack gear 31′a is connected to a lower surface of the cover 31′ while being laid on the humidity control member 35 elongated.
The slot 35 a extends longitudinally from a rear end of the humidity control member 35 toward a front end of the humidity control member by a desired length. The slot 35 a allows the second connecting member 33 b′ to move therein, to allow the container body 33′ to move forward or rearward. Guide members 35 b, not to be confused with guide member 32, are attached to the upper surface of the humidity control member 35 outside the rack gears 31′a and 33′a, respectively. The guide members 35 b guide the first and second rack gears 31′a and 33′a during movements of the first and second rack gears 31′a and 33′a so that the first and second rack gears 31′a and 33′a move without being laterally joggled.
Although a rack-and-pinion mechanism including the rack gears 31 a, 33 a, 31′a, and 33′a, and the pinions 34′ are shown, and the first and second rack gears 31 a, 33 a, 31′a, and 33′a are connected to the cover 31, and 31′ and container body 33, and 33′ by way of the first and second connecting members 31 b, 33 b, 31′b, and 33′b each having a pin structure, it will be appreciated by those skilled in the art that other members may be used within the scope of the invention. Moreover, it is understood that other mechanisms (such as hydraulic, elastic, pulley systems) can be used to create similar relative movement between the cover and the storage container body.
Now, respective operations of the refrigerator 1 equipped with the storage containers 12, 30 according to the above described embodiments of the present invention will be described in detail.
In the case of a conventional refrigerator equipped with a storage container having a large size, as described above, there is a problem in that the storage container may be incompletely opened even in a completely opened sate of a door of the refrigerator because the door of the refrigerator interferes with the opening operation thereof. For this reason, it is impossible to put food having a large size into the storage container through an access opening provided at the storage container because the access opening of the storage container is narrow. Typically, the opening operation of the storage container is carried out as the user draws the storage container forward from a front end of the refrigerator.
FIGS. 2 and 3 illustrate opened and closed states of the storage container according to one first embodiment of the present invention, respectively. The operation of the storage container 30 according to this embodiment will now be described.
The storage container 30 is arranged beneath the upper storage container 12. Although the storage container 30 is laid on a bottom surface of the housing 10 in the illustrated embodiment of the present invention, the storage container 30 may be installed at other portions of the housing 10. For instance, if the storage container 30 was installed below a shelf 11, the shelf 11 could be movable or have a movable cover portion. Further, the storage container 30 could be installed on a door 20 as needed. The storage container 30 can be drawn forward by a predetermined length beyond the upper storage container 12, so that the storage container 30 may be opened from the closed state thereof shown in FIG. 2.
When the user draws the storage container 30 forward out of the housing 10, the container body 33 of the storage container 30, as shown in FIG. 3, is moved forward, along with the second rack gear 33 a, while rotating the pinion 34 engaged with the second rack gear 33 a in a clockwise direction in FIG. 3. In accordance with the rotation of the pinion 34, the first rack gear 31 a engaged with the pinion 34 is moved rearward, so that the cover 31 is rearwardly moved into the housing 10 by a length corresponding to the length the first rack gear 31 a is moved.
At this time, the guide member 32 slidably fitted in the groove of the cover 31 guides the movement of the cover 31. The guide member 32 may also prevent the cover 31 from moving into the housing 10 beyond a predetermined length. Of course, the curved surfaces provided at the front and rear ends of the elongated groove of the cover 31 serve as stoppers ensuring that the cover 31 may move forward and rearward within a given movement length. However, it is understood that such stoppers are not always required, such as to allow removal of the container 33 for cleaning, and that additional guides can be used to regulate movement.
Thus, when the user draws the storage container 30 forward, the container body 33 moves forward and the cover 31 is moved rearward into the housing 10 by a length that corresponds to the length the container body 33 is moved forward within a movement length range determined by the length of the first and second rack gear 31 a or 33 a. Accordingly, there is an effect that the opened degree of the access opening of the container body 33 is doubled. There is also an advantage in that such an effect is achieved in accordance with an operation of simply opening the container body 33 without using an additional driving device. However, it is understood that a 1:1 forward-rearward ratio need not always be used, and that other ratios may be desired. It is further understood that driving devices, both manual and mechanical, can be additionally used to facilitate the opening/closing process.
FIGS. 4 and 5 illustrate opened and closed states of the storage container 30′ according to the another embodiment of the present invention, respectively. The operation of the storage container 30′ according to this embodiment will now be described. Similar to the embodiment shown in FIGS. 2 and 3, the cover 31′ is moved rearward into the housing 10 in accordance with operations of the first and second rack gears 31′a and 33′a, and pinion 34′ carried out as the user draws the container body 33′ forward. In this case, the humidity control member 35 mounted to the housing 10 is configured to allow the movement of the container body 33′. However, where no humidity control member 35 is to be used, it is understood that the gear 33′a can be attached at the container body 33′.
Since the second rack gear 33′a is connected to the container body 33′ using of the connecting member 33′b, the second rack gear 33 a is moved forward out of the housing 10 in a state of being engaged with the pinion 34′ when the user forwardly draws the container body 33′. At this time, the pinion 34′ is rotated. As a result, the first rack gear 31′a engaged with the pinion 34′ is moved rearward into the housing 10 because the pinion 34′ is rotatably mounted to the fixed humidity control member 35.
As is apparent from the above description, the refrigerator according to an aspect of the present invention includes the storage container in which the cover adapted to cover the container body is rearwardly moved when the container body is drawn forward to be opened, so that the opened degree of the storage container is increased. Accordingly, placing food, having a large size into the storage container and removing food stored in a rear inner portion of the storage container is possible, thereby securing the utility of the large-size storage container while providing an improved convenience in use to the user.
While described in terms of refrigerators, it is understood that such a system could be used in other types of storage containers, such as in coolers, food bins in a pantry, clothing drawers, file cabinets, computers and disc drives, or in any device where access to hold items is required and space is restricted.
Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
