Refrigerator {refrigerator}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a refrigerator, and more particularly, to a refrigerator in which a user can easily pull in / out a stored product. More particularly, the present invention relates to a refrigerator which can easily use a drawer for receiving a stored product.

Generally, a refrigerator discharges cold air generated by a refrigeration cycle including a compressor, a condenser, an expansion valve, an evaporator, etc. to lower the temperature of the inside of the refrigerator and freeze or refrigerate food or the like.

The refrigerator generally comprises a freezing room for storing food or beverage by freezing as a storage room, and a refrigerator for storing the food or beverage at a low temperature.

The refrigerator includes a top mount type in which a freezing compartment is disposed in an upper portion of a refrigerating compartment, a bottom freezer type in which a freezing compartment is disposed in a lower portion of the refrigerating compartment, a side by side type compartment in which a freezing compartment and a refrigerating compartment are divided into left and right (Side By Side Type). In this case, each of the freezer compartment and the refrigerating compartment is provided with a door, and the freezing compartment or the refrigerating compartment can be accessed through the door.

In addition to the refrigerator in which the refrigerator compartment and the freezer compartment are separated from each other, there is a refrigerator which allows access to the freezer compartment and the refrigerator compartment through a single door. Such a refrigerator is generally small in size, and a freezer is generally provided in a certain space inside the refrigerator compartment.

Also, among the top mount type refrigerators, there is provided a French type refrigerator in which the upper refrigerating chamber is opened and closed through the right and left doors. The freezer compartment of the French-type refrigerator can also be opened and closed through the right and left doors.

The refrigerator compartment and the freezer compartment are generally provided with a shelf in which the stored product is placed and a storage box containing the stored product. The storage box is generally provided to form an independent storage space in the storage room. That is, a storage box may be provided to store vegetables, fruits, etc., independently of other storage materials, or to store meat, oysters, etc. separately from other storage materials.

Recently, the capacity of the refrigerator has been increasing. Therefore, since the front and rear widths of the storage room such as the refrigerator compartment and the freezer compartment become large, it is not easy to take stored stored contents deep inside. Therefore, most of the storage boxes are provided in the form of drawers. That is, the user pulls out the storage box by pulling it out and can take out the stored contents. In particular, most of these drawer-type storage boxes are provided in the lower area of the refrigerator, thereby enhancing the user's convenience.

In recent years, a home-bar, an ice maker, a shelf or a door box is mounted on a rear surface of a door of a refrigerator, and the rear surface of the door is used as a separate storage space or as a separate functional space have. That is, the function of the door merely goes beyond opening and closing the freezer compartment or the refrigerating compartment, and the door forms an additional storage space or performs additional functions such as the generation and supply of ice or cold water. For this reason, the distance that the rear surface of the door is drawn into the refrigerator compartment or the freezer compartment is getting longer. Therefore, there may arise a problem that the front end portion of the shelf or the storage box provided in the back surface of the door and the freezing chamber or the freezing chamber interferes with the rear surface of the door.

In order to reduce such interference, the front end of the shelf or the storage box may be spaced a predetermined distance rearward from the front surface of the refrigerator. That is, the front end of the shelf or the storage box may be positioned further behind the freezer compartment or the refrigerating compartment. Therefore, when the storage box is provided in the form of a drawer, it may be difficult for the user to grasp the front end of the storage box and pull it out. In other words, the user may have difficulty in putting his / her hand deep into the storage compartment and taking out the storage box. Particularly, when the storage box is located at the lower portion of the refrigerator, it is not inconvenient to extend the hand from the crooked posture and pull out the storage box.

This inconvenience can be easily understood when the user opens the door to open the storage box and imagines that the front end of the storage box (i.e., the handle of the storage box) is not in front of the user but deep in the storage room.

The present invention basically aims to solve the problem of a conventional refrigerator.

According to an embodiment of the present invention, there is provided a refrigerator wherein a drawer provided in a storage compartment is drawn forward a predetermined length when a user opens a door of the refrigerator. That is, the drawer is to be automatically moved from the initial position to the operating position.

According to an embodiment of the present invention, there is provided a refrigerator in which a drawer is pulled in / out by a mechanism interlocked with an operation of a door when a user opens and closes the door of the refrigerator. Another object of the present invention is to provide a refrigerator which can be easily manufactured using a bridge having a very simple and simple structure and can remarkably reduce the storage space by the bridge.

It is an object of the present invention to provide a refrigerator in which a user can manually draw a drawer manually.

According to an embodiment of the present invention, there is provided a refrigerator capable of reducing cold air loss in a storage room through a bridge for interlocking a door with a drawer. In particular, it is desirable to provide a refrigerator which can reduce the loss of cold air both in the closed state of the door and in the open state thereof.

According to an embodiment of the present invention, there is provided a refrigerator capable of preventing a bridge for interlocking a door with a drawer from interfering with a copper wire of a user. In addition, it is desirable to provide a refrigerator in which the bridge is connected to each of a plurality of drawers, thereby minimizing a decrease in the storage space.

According to an embodiment of the present invention, there is provided a refrigerator in which a drawer in / out can be interlocked with the operation of a single door.

According to an aspect of the present invention, there is provided a cabinet comprising: a cabinet having a storage chamber; A door rotatably installed in the cabinet to open and close the storage compartment; A drawer provided in the storage room; A door that is provided to connect the drawer and the door so as to draw the drawer when the door is opened and to draw the drawer when the door is closed so as to interlock the opening and closing of the door with the draw- ; And a locking device for selectively releasing the interlocking operation of the door and the drawer to allow the user to further pull out the drawer when the door is opened.

One end of the bridge is rotatably provided on the door, and the other end of the bridge is connected to a side of the drawer. Therefore, the bridget for interlocking the movement of the drawer and the door can be directly connected to the door and the drawer.

The other end of the bridge may be provided with a latching member, and an inner wall of the storage chamber may be provided with a guide for guiding the linear movement of the protrusion. The guide guide may be formed in the longitudinal direction in the form of a groove or a slot. Therefore, it can be referred to as a guide groove.

The bridge may be provided so as to cover a space between the door and the opening of the storage room in a state where the door is opened. And, with the door closed, it can be positioned so as to be parallel to the inner wall or the inner surface of the storage chamber. The inner wall of the storage chamber means one side wall.

It is preferable that the bridge is formed in a plate shape in which buckling is excluded when the other end of the bridge is pressed or pulled at one end of the bridge by opening and closing the door.

The bridge is preferably made of stainless steel or aluminum.

One end of the bridge may be provided in a door dike of the door inserted into the opening of the storage room when the door is closed. More specifically, it may be provided on one side of the door dike. One side of the door dike may be a side facing the inner wall or the inner side of the storage compartment in a state where the door is closed.

In the left and right center of the door, one end and the other end of the bridge are preferably provided on one side of the drawer and on one side of the door, respectively.

In a state where the door is closed, the other end of the bridge is positioned closer to the left and right center of the door than one end of the bridge.

And the rotation axis of the door is located farther from the left and right center of the door than the one end of the bridge. Preferably, one end of the bridge is positioned radially inward of the gasket that closely contacts the door with the cabinet.

As the door is opened, the angle between the bridge and the inner surface of the storage chamber is preferably increased.

The bridge can perform a double sealing function by the position of the one end of the bridge and the shape of the bridge.

First, in a state in which the door is closed, the bridge blocks the cold air flowing into the gasket. Therefore, the gasket and the double seal function are performed.

And, in a state in which the door is open, the bridge divides the front area and the one side area of the cabinet. Therefore, it is possible to prevent the cool air leaking to the front of the cabinet from escaping to one side of the cabinet.

Preferably, the locking device is provided at the other end of the bridge and is interlocked with the opening of the door so that the door can be released after the drawer is drawn out. The locking device is preferably formed mechanically.

The interlocking lock and the interlocking can be performed by the force applied by the user. For example, the interlocking can be released by the force of drawing the drawer, and conversely, the interlocking can be performed by the pushing force of the drawer.

A hook may be formed on one side of the drawer, and the locking device may include an engaging member selectively engaged with the hook. When the latching member is engaged with the latching member, the latching member is released from the latching member.

The engaging jaw is preferably formed in a front and rear direction so that the drawer can be pulled out / pulled out by the bridge when the latching member is caught by the latching jaw of the latching portion.

Preferably, the locking device includes an elastic member that provides an elastic restoring force in a direction in which the latching member is caught by the latching jaw.

A plurality of the drawers are provided in the upper and lower portions, and the engaging members and the engaging portions can be provided to correspond to the respective drawers, respectively, so that the drawers can be manually drawn out after releasing the interlocking individually.

Preferably, the plurality of drawers are integrated with each other through a single door and a single bridge. Specifically, one end of a single bridge is connected to the door and the other end is connected to each drawer. Thus, the rotation of a single door is converted into a movement of a plurality of drawers by a single bridge.

Here, the bridges are connected to the sides of the individual drawers, respectively. Thus, a force is applied directly on the side of the individual drawer. Thus, this force is parallel to the direction of travel of the drawer, and it is possible to apply force to the drawer at a position adjacent to the draw rail position. Therefore, when a plurality of drawers are integrally linked, it is possible to minimize a force applied to a specific drawer.

In addition, the bridge may be positioned so as to be very close to the storage compartment inner wall or the inner compartment in the closed state of the door, and may be parallel to the storage compartment inner wall or the inner wall. Then, the entire drawer can be interlocked by the bridge. That is, a frame connecting a plurality of drawers can be omitted. Thus, it is possible to minimize the reduction of the storage space by the bridge.

According to an aspect of the present invention, there is provided a cabinet comprising: a cabinet having a storage chamber; A door rotatably installed in the cabinet to open and close the storage compartment; A drawer provided in the storage chamber; The door is connected to the door so that the drawer is pulled out when the door is opened and the drawer is pulled when the door is closed so that the opening and closing of the door and the drawing of the drawer are interlocked Wherein the bridge is provided to cover a space between the door and the opening of the storage compartment in a state that the door is opened. That is, the bridge can be partitioned into left and right in a state in which the gap extends vertically while the door is opened.

One end of the bridge is rotatably provided on the door, and the other end of the bridge is connected to a side of the drawer.

Preferably, one end of the bridge is located radially inward of the gasket that closely contacts the door with the cabinet. This enables double sealing.

According to an aspect of the present invention, there is provided a cabinet comprising: a cabinet having a storage chamber; A door rotatably mounted on one side of the cabinet to open and close the storage compartment; A drawer installed in the storage room in a state in which the door is closed and being drawn out in front of an opening of the storage room in a state that the door is opened; The door is connected to the door so that the drawer is pulled out when the door is opened and the drawer is pulled when the door is closed so that the opening and closing of the door and the drawing of the drawer are interlocked Wherein one end of the bridge is rotatably connected to the door and the other end of the bridge is connected to one side of the drawer and is linearly moved back and forth with respect to the inner surface of the storage chamber. May be provided.

And a guide guide or guide groove for guiding the other end of the bridge linearly is formed on the inner side surface of the storage chamber.

One end of the bridge is preferably positioned between the rotation axis of the door and the other end of the bridge, as a left and right reference.

Wherein one end of the bridge rotates while moving forward of the refrigerator while rotating about the rotation axis of the door when the door is opened and the other end of the bridge is moved forward of the refrigerator by forward movement of one end of the bridge .

Preferably, the bridge is formed of a material having a rigidity such that one end of the bridge excludes buckling so as to transmit the pulling force and the pushing force of the other end of the bridge.

In the above embodiments, the door rotates through the rotation shaft provided on the right side of the refrigerator. However, the present invention is equally applicable to a door that rotates through a rotary shaft provided on the left side of the refrigerator. Of course, the same can be applied to the refrigerator door as well as the freezer door.

According to an embodiment of the present invention, when a user opens a door of a refrigerator, a drawer provided in a storage compartment can be extended to a predetermined length forward. That is, it is possible to provide a refrigerator in which the drawer automatically moves from the initial position to the operating position.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a front view of a refrigerator 1 according to an embodiment of the present invention. There is shown an example of a four-door refrigerator having a refrigerating chamber 11 at the top and freezing chambers 12 and 13 at the bottom. For the sake of convenience, the left and right doors of the upper refrigerator compartment are omitted, and the left door of the lower freezer compartment is omitted, and only the right door 20 of the lower freezer compartment is shown. Of course, the present embodiment is applicable not only to this type of refrigerator but also to a side-by-side refrigerator. That is, the present embodiment can be applied to a refrigerator having a door for opening and closing the storage chamber and a drawer for moving the storage chamber back and forth.

The refrigerator includes a cabinet 10 having storage rooms 11, 12 and 13 and a door 20 rotatably installed in the cabinet and opening and closing the storage room. As described above, if there are a plurality of storage rooms, a plurality of doors may be provided correspondingly.

The refrigerating compartment 11 and the freezing compartments 12 and 13 may be partitioned from each other through a horizontal partition 14. The left freezer compartment 12 and the right freezer compartment 13 may be separated from each other through separate side walls or partitions 16. [ The barrier ribs 16 may be referred to as vertical barrier ribs for the sake of convenience. The refrigerator compartment 11, the left freezer compartment 12, and the right freezer compartment 13 may be opened and closed by individual doors, respectively.

A drawer 30 may be provided in the storage rooms 11, 12 and 13, and in particular, the freezing compartments 12 and 13, including a basket 31 for storing stored contents. A plurality of the drawers 30 may be provided up and down. FIG. 1 shows an example in which three drawers 30a, 30b and 30c are provided in the right and left freezers, respectively. Of course, this embodiment can be applied to a case where a drawer is provided in a freezer compartment as well as a freezer compartment. In addition, one or two drawers may be interlocked with a door on one door, and four or more drawers may be automatically interlocked with the door.

The present embodiment is intended to provide a refrigerator in which the drawer 30 can be moved for the convenience of the user in cooperation with the opening and / or opening / closing of the door 20. For example, as the right freezer compartment 13 is opened or closed through the door 20, the drawer 30 provided in the right freezer compartment 13 can be moved in conjunction with the door to provide a refrigerator .

FIG. 2 shows only the lower freezing compartments 12 and 13 in the refrigerator shown in FIG. 1. The left freezing compartment door is in a closed state, and the right freezing compartment door 20 is in an open state.

As shown in the drawing, the drawer 30 provided in the left freezer compartment may be further inserted into the storage compartment than the drawer provided in the right freezer compartment. 2, the position of the drawer 30 provided in the left freezer compartment may be referred to as an initial position and the position of the drawer 30 provided in the right freezer compartment may be referred to as an operating position.

In other words, the drawer 30 in a state in which the door 20 is closed is located at the initial position, and the drawer 30 in the state in which the door 20 is opened can be said to be located at the operating position .

As described above, a storage box or basket (23) is provided on the rear surface of the door (20), and a separate door storage area (21) can be formed through the storage box and the basket (23). In order to eliminate the interference between the door 20 and the drawer 30, particularly the interference between the basket and the drawer 30 provided in the door, the drawer is drawn to the initial position in a state where the door 20 is closed. That is, since the basket 23 provided on the rear surface of the door 20 is drawn into the storage chamber, the drawer is drawn further backward than the basket 23.

When the user opens the door 20 to withdraw the stored product, the drawer 30 is moved from the initial position to the forwardly moved operating position so that the user can more easily draw the drawer. Therefore, since the front end of the drawer or the handle 35 is moved to a position closer to the user, the user can more easily draw the drawer.

That is, the initial position may be a draw position in a state where the drawer is substantially moved to the inside of the storeroom, and the operation position may be a position spaced a predetermined distance forward from the initial position. In this operating position, the user can operate the drawer 30 very conveniently because he or she does not need to put his / her hand deep into the storage room to hold the handle 35. [ On the other hand, the operation position may be referred to as a standby position. This is because, on the drawer side, it may be a position waiting for user's operation.

As shown in Fig. 2, it is preferable that the drawer 30 does not depart from the opening 17 of the storage chamber even in the operating position. That is, even if the door 20 is opened, it is preferable that the front end of the drawer 30, particularly the drawer, or the handle 35 is positioned behind the opening 17. That is, it is preferable that the drawer 30 is still positioned inside the storage chamber. This is because opening the door 20 by the user may not necessarily be intended for use or withdrawal of the drawer 30. [ For example, the door 20 may be opened to use the door storage area 21. Further, when there are a plurality of drawers 30, drawers 30 which are not drawn out can be taken out of the storeroom only because specific drawers can be taken out, which causes only cold loss.

Here, the opening 17 of the storage chamber may be referred to as an inlet of the storage chamber. The door 20 substantially blocks the opening 17, so that the cool air in the storage compartment can be sealed.

As will be described later, the embodiment of the present invention can provide a refrigerator in which the travel distance of the drawer is changed according to the door opening manner of the user, particularly, the door opening angle. This prevents unnecessary movement of the drawer, thereby reducing cold loss and energy loss. In addition, it is possible to provide a refrigerator in which the interference between the drawer and the door can be minimized.

Also, when the door is opened, the cold air in the storage room is basically lost. As the drawer is drawn, the cold air inside the drawer's basket is also lost. That is, as the draw-out length of the drawer increases, the loss of cold air in the basket accelerates, and the loss of cold air can be further accelerated, especially when the drawer is drawn further forward than the opening. Therefore, in order to minimize the loss of cold air inside the basket at the operating position, it is preferable that the drawer (30) does not escape from the inside of the storage chamber even at the operating position of the drawer. That is, it is preferable that the front end of the drawer 30 is not exposed more forward than the opening 17.

The operating position may be, for example, a position shifted approximately 120 mm forward from the initial position. Of course, the interval between the operation position and the initial position may be set differently depending on the shape of the refrigerator, the position of the drawer, the distance the door 21 is drawn into the storage compartment, and the capacity of the refrigerator. However, it is preferable that the operating position is a position where the front end of the drawer or the handle 35 does not come out of the opening 17 of the storage room. That is, it is preferable that the front end portion or the handle is located inside the opening portion without leaving the opening portion.

The present embodiment relates to a refrigerator in which a drawer provided in the storage compartment in cooperation with the door when the door 20 for opening and closing the storage compartment is opened is moved (drawn out) from the initial position to the operation position. Accordingly, the refrigerator according to the present embodiment includes a bridge for moving the drawer.

Hereinafter, the bridge of the refrigerator according to the present embodiment will be described in detail with reference to FIG.

As shown in FIG. 3, the bridge 100 is provided between the drawer 30 and the door 20. That is, the bridge 100 is provided to connect the drawer 30 and the door 20. Therefore, the movement of the door 20 can be switched to the movement of the drawer 30 by the bridge 100. Specifically, the rotational movement of the door 20 can be switched to the linear movement of the drawer 30. [

As the opening angle of the door 20 increases, the bridge pulls the drawer 30 out. On the contrary, when the opening angle of the door 20 becomes smaller, the bridge 100 moves the drawer 30, .

Meanwhile, as shown in FIG. 3, the bridge 100 is preferably positioned between the drawer 30 and the door basket 23. That is, on the basis of the drawer 30 and the basket 23 shown in FIG. 3, the bridge 100 is positioned on the right side of the drawer 30 and on the left side of the basket 23. Therefore, the bridge 100 does not interfere with the drawer 30 or the basket 23. [ That is, when the user uses the drawer 30 or the basket 23, the copper line of the user and the bridge 100 do not interfere with each other. This is because the bridges 100 are located at corner portions where one side of the storage room and one side of the door correspond to each other. Therefore, when the user approaches the drawer 30 or the door basket 23, it is not interfered with by the bridge 100.

As shown in FIG. 3, a plurality of the drawers 30 may be provided. The plurality of drawers 30 can be arranged vertically. The plurality of drawers 30 can be interlocked with the opening and closing of one door 20. [ For this purpose, the bridge 100 may be provided in the door 20 and each drawer 30. That is, a plurality of bridges 100 may be provided.

However, it is preferable that one bridge 100 is connected to the door and each drawer 30. That is, one bridge 100 is preferably connected to each of the plurality of drawers 30. Accordingly, a plurality of drawers 30 can be interlocked with one door through one configuration. For this purpose, the bridge 100 may be provided in a plate shape extending vertically. One end of the bridge 100 may be connected to the door and the other end may be connected to the respective drawers.

The bridge 100 directly connects the door 20 and the drawer 30. In other words, a force is directly applied to the drawer 30 itself through the bridge 100. In other words, the bridge 100 directly pushes or pulls the drawer 30. This means that a separate configuration between the bridge 20 and the drawer 30 interlocked with the opening and closing of the door 20 can be omitted.

For example, a plurality of drawers may be connected by a specific frame, and the particular frame may be linked to a link associated with the door. Accordingly, the specific frame is moved back and forth through the link, and the drawer can be moved back and forth through the link. Here, the link has a function similar to that of the bridge in the present embodiment.

However, in the present embodiment, a separate frame or configuration for connecting the plurality of drawers 30 may be omitted. That is, one bridge can simultaneously perform a frame and a link function. In other words, the plurality of drawers 30 can be interlocked with one door 20 simultaneously by the structure and the shape of the bridge 100 itself. This means that the bridge 100 pushes or pulls the individual drawers directly rather than pushing or pulling the separate frames.

In addition, the bridge 100 is located on the side of the drawer 30 and the door basket 22. This means that the storage area reduction by the bridge 100 can be minimized. In addition, since the frame structures for integrally linking the plurality of drawers 30 can be omitted, it is possible to minimize the storage space area reduction by such a configuration.

Since one end of the bridge 100 is connected to the respective drawers 30, a force can be applied to the drawers 30 in the same direction as the draw-in and draw-out directions of the drawers 30. Therefore, when the door (20) is opened and closed, the drawer (30) is pulled in / out, so that the user does not use excessive force. The position and the shape of the bridge 100 have the effect of enabling double sealing as described later.

Hereinafter, the structure of the bridge 100 described above with reference to FIGS. 4 and 5 will be described in detail. 4 and 5 are enlarged cross-sectional views of only the periphery of the bridge 100 positioned between the drawer 30 and the door 20. 4 shows a state in which the door 20 is closed, and Fig. 5 shows a state in which the door 20 is opened.

The drawer 30 is drawn into the storage chamber 13 with the door 20 closed. The basket 23 and the door duck 24 provided on the rear surface of the door 20 are also drawn into the storage chamber 13. That is, a portion of the drawer 30, a portion of the basket 23, and a portion of the door dike 24 are located further rearward than the storage compartment opening 17. At this time, the drawer 30 and the basket 23 are positioned facing each other.

The bridge 100 is provided to connect the drawer 30 and the door 20 in order to interlock the door 20 and the drawer 30. That is, one end 120 of the bridge 100 is connected to the door 20 and the other end 110 is connected to the drawer 30.

Specifically, one end of the bridge 100 may be provided on the door dike 24 of the door. For example, when the rotary shaft of the door 20 is positioned on the right side of the cabinet 10, one end of the bridge 100 may be provided on the right side of the door dike 24. Therefore, interference between the bridge 100 and the basket 23 can be eliminated. The other end of the bridge 100 is preferably positioned between one side of the door dike 24 and the storage compartment inner wall 13a in a state where the door 20 is closed. The inner wall 13a of the storage compartment is formed to have a width wider from the front so that the door duck 24 and the door basket 30 can smoothly enter the storage compartment through the storage compartment opening 17 when the door 20 is opened and closed. . At this time, the bridge 100 may be positioned to be parallel to the inner wall or the inner side surface 13a of the storage chamber. Thus, interference between the door dike 24 and the bridge 100 can be eliminated.

4, it is preferable that one end of the bridge 100 is positioned radially inward of the gasket 22 in which the door 20 and the cabinet 10 are in close contact with each other. That is, since the bridge 100 is positioned radially inward of the gasket 22, it does not affect the sealing by the gasket 22. As described below, this bridge 100 enables double sealing.

In addition, the other end 110 of the bridge 100 may be positioned on a side surface of the drawer 30. For example, when the rotary shaft of the door 20 is positioned on the right side of the cabinet 10, the other end of the bridge 100 may be provided on the right side of the drawer 30.

5, when the door 20 is opened while rotating about the door rotation axis 25, the one end 120 of the bridge 100 similarly rotates about the door rotation axis 25 . That is, as the rotation angle increases, the one end 120 of the bridge 100 moves further forward with respect to the cabinet 10.

That is, the rotation for opening the door 20 causes the movement of the one end 120 of the bridge 100. Here, the other end 110 of the bridge 100 also moves forward by the forward movement distance of the end of the bridge 100. [ That is, one end (120) of the bridge (100) pulls the other end (110).

The other end (110) of the bridge is connected to the drawer (30). Specifically, the other end of the bridge 110 may be provided on the front side of the drawer 30. Therefore, the forward movement of the other end 110 of the bridge causes the movement of the drawer 30.

Meanwhile, the bridge 100 may be provided to transmit not only the pulling force but also the pushing force. That is, it is preferable that the rotation for opening the door allows the drawer to be drawn out, and that the rotation for closing the door can draw the drawer. That is, it is preferable that the material and shape of the bridge 100 itself can withstand the pulling force and the pushing force through the bridge 100.

For example, when the bridge 100 is a rope, a pushing force is hardly transmitted. This is because when the pushing force is applied in the longitudinal direction of the rope, it is difficult to transfer the force due to the buckling of the rope. Therefore, the bridge 100 can be manufactured so that when one end 120 of the bridge pushes the other end 110, buckling is excluded and the bridge 100 can endure the buckling. For example, the bridge may be made of stainless steel or aluminum and may be manufactured to have a predetermined thickness to prevent buckling.

Such a metal material has a temperature effect. That is, it is characterized in that it is rapidly cooled when cold air is supplied. This can be said to be the effect of the product. Therefore, the design of the inside of the refrigerator can be made more beautiful.

One end of the bridge 100 moves not only forward and backward but also right and left as the door rotates. Therefore, it is preferable that one end of the bridge 100 is rotatably coupled to the door 20. Whereby the pulling or pushing force of the drawer through the bridge 100 can be smoothly transmitted regardless of the angle of rotation of the door.

4 and 5, one end 120 of the bridge 100 is positioned between the other end 110 of the bridge 100 and the door rotation axis 25 as a left and a right reference. As the opening angle of the door 20 increases, the angle between the bridge 100 and the storage chamber inner surface 13a increases. This is because as the opening angle of the door increases, the other end 110 of the bridge 100 linearly moves forward, but the other end of the bridge 100 moves forward and moves to the right.

As shown in FIG. 5, as the door 20 is opened, spaced spaces A and B are generated between the opening 17 and the door 20 of the storage compartment. Therefore, the cold air inside the storage chamber can leak into the spaced spaces A and B. Generally, both sides of the drawer 30 are as close as possible to both sides of the storage compartment. Therefore, most of the cold air inside the storage compartment can leak out from the draw part, not both sides of the storage compartment.

As shown in FIG. 5, generally, when the door 20 is opened, most of the cold air in the storage compartment is exposed to the spaced space B in front of the drawer. Then, the cold air is spread on both sides in the space (B), and more particularly, it can leak through the right space (A) between the drawer and the door.

In the present embodiment, the spaced spaces A and B can be partitioned through the bridge 100. Accordingly, when the door 20 is opened, a space in which cold air can leak is reduced. This is because the substantially right spaced space A by the bridge 100 can be isolated from the spaced apart space B located in front of the drawer.

Accordingly, it is possible to reduce the outflow of cold air in a state in which the door 20 is opened through the bridge 100. Of course, as will be described later, the outflow of cold air can be further reduced even when the door 20 is closed through the bridge 100.

As described above, the one end 120 of the bridge can be rotatably provided on the back surface of the door 20, particularly the door dike 24. And is preferably positioned radially inward of the door gasket 22 at one end 120 of the bridge. Thus, the basic heat insulating property by the door gasket 22 is not deteriorated. Further, the drawer is drawn or drawn in conjunction with the opening and closing operation of the door through the bridge (100).

However, considering the use form of the drawer 30 by the user, the interlocking between the door 20 and the drawer 30 needs to be released. Specifically, it is necessary to be able to draw the drawer 30 further forward in a state where the door 20 is stopped while the door 20 is opened.

For example, in the state shown in FIG. 5, the user may take out the drawer 30 further forward to take out the stored product inside the drawer 30. FIG. To this end, the present embodiment can provide a locking device that selectively allows interlocking between the door 20 and the drawer 30. The door 20 and the drawer 30 are interlocked by the lock setting of the lock device so that only the drawer 30 can be manually entered / extracted by unlocking.

That is, as described above, it is possible to provide a lock device in which lock can be set at all times in the interval between the initial position of the drawer and the operating position, and the unlocking is performed in order to further withdraw the drawer at the operating position. Of course, it is preferable that unlocking is also performed when manually pulling the drawer from the state in which the drawer is pulled out to the maximum forward position.

Here, the locking device 200 may be a device that operates mechanically. That is, the lock can be set and released through a force applied by the user to the drawer 30. [

Hereinafter, the locking device 200 will be described in detail with reference to FIG. The illustrated locking device 200 is a conceptual view showing an enlarged view of the locking device shown in Figs. 4 and 5. Fig.

The locking device 200 may be provided for connecting or disconnecting the bridge 100 and the drawer 30.

The locking device 200 may be provided at the other end 110 of the bridge 100. Specifically, it may include an engaging member 210 to be connected to the drawer 30. The drawer 30 may be provided with a latching portion 35 corresponding to the latching member 210.

The latching part 35 may be located on the front side of the drawer 30. [ When the latching member 210 is hooked on the latching portion 35, the lock of the locking device 200 is set and the bridge 100 and the drawer are interlocked with each other. On the contrary, the latching member 210 is not caught by the latching portion 35, and the locking device 200 is unlocked, so that the movement of the bridge 100 and the drawer 30 is not interlocked.

More specifically, the latching part 35 may include a front latching jaw 37 and a rear latching jaw 36 when viewed from top to bottom. 7, the downward direction is the pull-out direction of the drawer, and the upward direction is the pull-in direction of the drawer. Therefore, in a state in which the latching member 210 is engaged with the latching portion 35, the latching member 210 can push the front latching jaws 37 to pull the entire body forward. On the contrary, in a state in which the latching member 21 is engaged with the latching portion 35, the latching member 210 can push the rear latching jaw 36 downward to pull the whole backward.

Basically, the engagement of the latching member 210 with the latching part 35 can be performed in a section between the initial position of the drawer and the operation position. That is, when the door is closed, the drawer can be pulled to the initial position, and the drawer can be pulled out to the operating position while the door is fully opened.

When the user pulls the drawer 30 further forward from the operating position, the engaging member 210 can be released from the engaging portion 35 by the force that the user pulls the drawer. Likewise, when the drawer 30 is pulled out to the operation position, the engaging member 210 can be rejoined to the engaging portion 35 by a force that the user pushes the drawer.

In order to facilitate separation and recombination of the latching member 210, a latching protrusion 220 may be formed on the latching member 210. The locking protrusion 220 may be formed in a hemispherical shape. Therefore, the release and recombination through the forwardly engaging jaw 37 can be performed smoothly.

The engaging protrusion 220 is elastically moved in a direction substantially perpendicular to the direction of movement of the drawer, that is, in a direction away from the engaging member 210, by a force applied by the user through the drawer 30 . To this end, the locking device 200 may include an elastic member 240.

The locking device 200 may include a boss 230 for mounting the elastic member 240. And the locking protrusion 220 may be formed to extend from the boss 230. A spring-like elastic member 240 may be provided around the boss 230.

The bosses 230 may be provided to guide grooves 13b formed in the inner wall 13a of the storage compartment or guide guides. Accordingly, the latching member 210 can be moved back and forth along the guide groove 13b through the bosses 230. As shown in FIG. In other words, the other end 110 of the bridge 100 can be moved back and forth along the guide groove 13b through the engaging member 210. [

The elastic member 240 may be elastically deformed when the latching member 210 is moved to the latching position. That is, when the latching member 210 moves out of the latching portion 35, the latching member 210 is continuously pressed by the drawer 30, . The movement of the latching member 210 causes a relative positional difference with respect to the inner wall 13a of the storage chamber, whereby the elastic member 240 can be elastically deformed.

When the pressing force of the locking member 210 is removed, that is, when the locking member 210 is moved to the locking position, the locking member 210 is caught by the locking portion 35 due to the elastic restoring force of the elastic member do. That is, the latching member 210 can be returned to the latching position.

Meanwhile, a leaf spring 130 may be provided at the other end of the bridge 100. The leaf spring 130 may be disposed parallel to the other end of the bridge 100. When the leaf spring 130 is fixed, an elastic force or an elastic restoring force may be generated as the distance between the other end of the bridge 100 and the leaf spring 130 is changed.

Therefore, the leaf spring 130 itself can constitute an elastic member. Of course, the elastic member may be formed together with the above-described spring. 7 shows an example in which the plate spring generates an elastic force or an elastic restoring force, and at the same time, supports the spring to generate an elastic force or an elastic restoring force of the spring itself.

FIG. 6 shows the flow of cool air in a state where a door is closed in a conventional refrigerator.

Generally, the cold air can flow in from the rear of the storage chamber 13 forward. At a position close to the storage compartment inner wall 13a, the cold air can flow forward. At this time, a part of the cool air may flow into the door basket 23 and some may flow into the door basket 23 and the door dike 24. The cool air introduced into the door dike 24 flows along the gap between the door dike 23 and the storage compartment inner wall 13a and can further flow toward the gasket 22.

Basically, the storage chamber 13 is sealed to the heat insulating wall through the cabinet 10 and the door 20. However, the gasket 22 is sealed between the cabinet 10 and the door 20. Therefore, leakage of cold air from the gasket 22 is maximized at the sealing side of the storage chamber 13.

However, as shown in FIG. 4, it can be seen that the cold air leaking into the gasket 22 can be effectively reduced by the bridge 100 according to the present embodiment. This is because the bridge 100 blocks the gap between the door dike 24 and the drawer 35 when the door is closed. Thus, the cold air in the storage chamber is blocked by the bridge 100 before entering the space between the door dike 24 and the storage chamber inner wall 24. As a result, the cold air flowing into the gasket 22 can be effectively blocked. This means that the loss of cool air generated in the gasket 22 portion can be effectively reduced.

Accordingly, the storage chamber is capable of double sealing through the bridge 100 located radially inward of the gasket 22 as well as the gasket 22. Of course, such a sealing effect may be more effective when the bridge 100 is formed in a plate shape extending vertically.
