Description

Refrigerator {Refrigerator}

The present invention relates to a refrigerator.

Background Art [0002] A refrigerator is an appliance for storing foods in a low-temperature state, and generally includes a refrigerating chamber for storing food in a refrigerated state and a freezing chamber for storing the refrigerant in a frozen state.

Since the internal temperatures of the refrigerating and freezing compartments are lower than the room temperature, the internal and external heat insulation is most important. Particularly, it is very important to prevent the cold air from flowing out to the outside when the refrigerator door is opened, and to prevent the outside air from flowing into the inside of the refrigerator door.

Means for blocking this cold airflow is disclosed in Korean Utility Model Application No. 1998-1289, 1995-52959, and Korean Registered Utility Model No. 20-0256557.

In the case of the conventional cold shielding structure, it is difficult to operate the temperature adjusting means for adjusting the inside temperature in a state where the cold shielding member is vertically placed on the inside surface of the furnace. That is, there is an inconvenience that the cold blocking structure must be lifted in order to control the internal temperature. In addition, in the case of some cold-weather shielding structures, there is inconvenience in that the cold-shielding structure is lifted up with one hand and the food or container is taken out or stored with the other hand.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a refrigerator having a cold blocking structure that effectively blocks cold air flow and provides convenience of operation.

It is another object of the present invention to provide a refrigerator having a cold shutoff structure that enables operation for temperature control within a state in which cold air is shut off.

According to an aspect of the present invention, there is provided a refrigerator comprising: a main body having a storage chamber; A door connected to the main body and selectively opening and closing the storage chamber; A temperature regulating device provided on an inner surface of a point spaced a predetermined distance forward from the rear surface of the storage chamber; And a cool air outflow blocking cover selectively shielding the storage room to block out cold air from the inside of the storage room, wherein one edge of the cool air outflow blocking cover is rotatably coupled to the temperature control device.

According to the cold air shielding structure of the refrigerator having the above-described structure, the cold air outflow blocking cover effectively blocks the phenomenon that the hot air outflows to the outside or the outside air flows into the inside.

In addition, since the temperature control device can be operated in a state where the cold airflow blocking cover shields the high-temperature opening portion, there is an effect that the cold air leaks during the temperature control process is prevented.

Further, since the cold air outflow blocking cover is rotatably connected to the temperature adjusting device, there is no need to drill the inner wall surface for installing the cold air outflow blocking cover, and there is an advantage that the reduction in heat insulation can be minimized.

Further, if the cold airflow blocking cover is opened and rotated by a set angle or more, it automatically rotates in the direction of shielding the inside opening portion even if there is no user operation. Accordingly, it is possible to minimize leakage of cool air through a gap between the inner wall surface and the cool airflow blocking cover in a state where the refrigerator door is opened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a refrigerator provided with a cold airflow blocking cover according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a refrigerator showing a closed state of a cold airflow blocking cover according to an embodiment of the present invention, and FIG. 2 is a perspective view of a refrigerator showing a cold airflow blocking cover opened.

1 and 2, a refrigerator 10 according to an embodiment of the present invention includes a main body 11 and a door rotatably coupled to the front surface of the main body 11. As shown in FIG.

In detail, the main body 11 is provided with a refrigerating chamber and a freezing chamber 111. The door includes a refrigerating chamber door 12 for opening and closing the refrigerating chamber and a freezing chamber door 13 for opening and closing the freezing chamber 111 . In addition, a cool air outflow blocking cover 14 is provided on either or both of the refrigerating chamber and the freezing chamber 111 to block the flow of cold air. In this embodiment, the cold airflow blocking cover 14 is provided in the freezing chamber.

A storage box 131 may be fixedly or detachably coupled to a rear surface of the freezing compartment door 13 and a plurality of storage boxes may be coupled to a rear surface of the refrigerator compartment door 12.

In addition, a temperature regulating device 15 may be mounted on the inner wall of the storage space including the freezing chamber 111. The cool airflow blocking cover 14 is rotatably coupled to the temperature control device 15. [ A temperature control knob 151 for temperature setting may be rotatably provided on the front surface of the temperature control device 15.

In detail, the cool air outflow blocking cover 14 has a shape and a size corresponding to the shape and area of the storage space. That is, when the cold air outflow blocking cover 14 is closed, the edge of the cold air outflow blocking cover 14 is brought into contact with the inner edge of the storage space, and the refrigerator compartment door 12 or the freezing compartment door 13 is opened Minimizes leakage of hot air to the outside.

The cool air outflow blocking cover 14 may be made of a transparent material so that the inside air intrusion can be checked even when the cool air outflow blocking cover 14 is closed. A gripping groove 141 which can be grasped by the user is formed on one side of the cold airflow blocking cover 14 so that the cold airflow blocking cover 14 can be easily opened and closed. Particularly, it is preferable that the grip groove 141 is formed at the opposite edge of the edge where the rotation axis of the cool airflow blocking cover 14 is formed.

If the cold airflow blocking cover 14 is held while the food is taken out or stored in the state where the cold airflow blocking cover 14 is opened, the usability may be deteriorated. Therefore, it is preferable that the rotation center of the cold air outflow blocking cover 14 is formed at the edge except for the upper end of the cold air outflow blocking cover. For example, at the edge on the same side as the edge where the rotation axis of the door 13, .

FIG. 3 is a cross-sectional view showing a combined state of the cold airflow blocking cover according to the embodiment of the present invention, and FIG. 4 is a partial perspective view showing the hinge fitting state of the cold airflow blocking cover.

3 and 4, the cool airflow blocking cover 14 is rotatably coupled to the temperature control device 15 as described above.

In detail, the hinge device 200 is mounted in the temperature regulating device 15 and the shaft 400, which serves as the rotation center of the cool air outflow blocking cover 14, protrudes from the hinge device 200. The shaft (400) is inserted into a hinge groove (142) formed in the cold air outflow blocking cover (14). The shaft 400 and the hinge groove 142 may be formed in a flat key shape with chamfered sides. Then, in a state where the shaft 400 is inserted into the hinge groove 142, the cooling airflow blocking cover 14 and the shaft 400 rotate together.

The hinge device 200 is mounted on the upper and lower ends of the temperature regulating device 15 and the shaft 400 protruding from each hinge device 200 is connected to the upper surface of the temperature regulating device 15 And protrudes from the lower surface. The rotation center X of the cool airflow blocking cover 14 passes through the center of the shaft 400.

A depression 144 for receiving the temperature regulating device 15 is formed at a side edge of the cool airflow blocking cover 14 corresponding to the temperature regulating device 15. That is, the depression 144 is recessed along the outer circumferential shape of the temperature regulating device 15 so as not to interfere with the temperature regulating device 15 when the cool air outflow blocking cover 14 rotates. The front surface of the temperature regulating device 15 is exposed to the outside even when the cooling airflow blocking cover 14 is closed so as to shield the storage space by forming the depression 144. Therefore, it is possible to operate the temperature control knob 151 in a state where the cold air outflow blocking cover 14 is closed, and as a result, the refrigerator doors 12 and 13 Is opened, the cold air is prevented from flowing out.

Further, the temperature regulating device 15 is located at a position spaced forward from the inner rear surface of the storage space. In other words, when the refrigerator doors 12 and 13 are closed, they are provided at positions closer to the front surface of the storage space, that is, at a position not interfering with the storage box 131 provided in the doors 12 and 13 do. Therefore, there is an advantage that the user does not need to open the refrigerator door for temperature control and then put his hand deep into the storage space. In addition, since the temperature regulating device 15 is located in front of the storage space, the temperature control device 15 can be prevented from being covered by the food stored in the storage space. In detail, in a state where the cold airflow blocking cover 14 is closed, the front surface of the temperature adjusting device 15 is substantially flush with the front surface of the cold airflow blocking cover 14. This means that the food should be located behind the cool airflow blocking cover 14, which means that the temperature control device 15 is not blocked by the food.

Further, the temperature regulating device 15 is mounted on a side portion of the storage space, so that the action of taking out or storing the food is not disturbed by the temperature regulating device 15. [

FIG. 5 is an external perspective view of a hinge apparatus according to an embodiment of the present invention, and FIG. 6 is an exploded perspective view of the hinge apparatus.

5 and 6, a hinge device 200 according to an embodiment of the present invention includes a housing 300 having an external shape, a shaft 400 accommodated in the housing 300, A guide member 500 which is inserted into the outer circumferential surface of the shaft 400 and which linearly moves in the course of the rotation of the cool airflow blocking cover 14 and an elastic member fitted to the outer periphery of the shaft 400.

In detail, the housing 300 forms an outer shape of the hinge device 200 and may be formed into a cylindrical shape having a predetermined diameter. In addition, a receiving portion 310 for receiving various components such as the shaft 400, the guide member 500 and the elastic member therein, and a coupling portion 320 extending from the edge portion of the receiving portion 310 ). A plurality of fastening holes are formed in the coupling part 320, and the hinge device 200 is fixed to the inside of the temperature control device 15 by fastening members passing through the fastening holes.

Meanwhile, the housing 300 is separated into an upper housing and a lower housing so that a plurality of parts can be mounted therein, and is integrally coupled by a coupling member passing through the coupling part 320. A first through hole 340 through which one end of the shaft 400 penetrates and is exposed to the outside is formed at one end of the housing 300 and a second through hole 340 through which the other end of the shaft 400 penetrates is exposed at the other end. Two through-holes 360 are formed. In the drawing, the first through-hole 340 is formed on the right side of the housing 300, and the second through-hole 360 is formed on the left side.

Further, an orbit groove 380 is further formed on the inner circumferential surface of the housing 300. The orbital groove 380 guides the movement of the guide member 500 when the shaft 400 rotates together with the cold airflow blocking cover 14. The detailed structure and functions will be described later This will be described in detail.

Meanwhile, as shown in FIG. 6, a shaft 400 is provided inside the housing 300. The shaft (400) allows the cooling airflow blocking cover (14) to be rotatably and axially coupled to the temperature regulating device (15). The shaft 400 is a round bar having a predetermined diameter, and is composed of a main shaft 420 and a sub shaft 440.

In detail, the main shaft 420 protrudes from the housing 300 and is inserted into a hinge groove 142 formed in the cool airflow blocking cover 14. [ Accordingly, the main shaft 420 rotates with the cool airflow blocking cover 14 as one body.

The main shaft 420 includes a support portion 422 and a guide portion 424. The support portion 422 has a predetermined width from one end (the left end in the drawing) of the main shaft 420 and has a circular cross section. The support portion 422 supports the front end of the second elastic member 460, which will be described below, so that the second elastic member 460 can be compressed according to a user's operation. The second elastic member 460 compresses and expands in the process of inserting one end of the main shaft 420 into the hinge groove 142.

The guide portion 424 extends from the end of the support portion 422 to the other end portion (the right end portion in the drawing) of the main shaft 420. In detail, the guide portion 424 has a chamfered left and right side surfaces of a round shaft-shaped shaft, and has a flat key shape as a whole. The guide member 500 is inserted into the outer circumferential surface of the guide portion 424 and the guide member 500 is moved forward and backward along the guide portion 424 in the process of opening / Backward.

A sub shaft 440 is mounted on the other end of the main shaft 420 (left end in FIG. 6).

In detail, the sub shaft 440 is coupled to the main shaft 420 at the other end of the main shaft 420 to restrict the main shaft 420. The sub shaft 440 may have a round bar shape having a smaller diameter than the main shaft 420. The left end is formed to have a somewhat larger diameter as the head shape of the bolt, and the right end is formed to be threaded and screwed to the rear end of the main shaft 420. Here, it is noted that the sub shaft 440 may be formed separately from the main shaft 420, but may be formed as a single body with the main shaft 420.

The sub shaft 440 is inserted through the second through hole 360 on the left side of the housing 300 and passes through the second elastic member 460 from the inside of the housing 300, And is coupled to the rear end of the shaft 420.

In addition, the above-mentioned elastic member includes a first elastic member 540 and a second elastic member 460. The first elastic member 540 is fitted on the outer circumference of the main shaft 420 and has one end in close contact with the guide member 500 and the other end in close contact with the left inner peripheral surface of the housing 300. The second elastic member 460 is fitted on the outer periphery of the sub shaft 440 and has one end being in close contact with the support portion 422 of the main shaft 420 and the other end being in contact with the left inner peripheral surface of the housing 300 Respectively. Here, the left inner circumferential surface of the housing 300 refers to a surface opposite to the surface on which the guide member 500 is closely contacted as viewed in FIG. 6.

More specifically, the first elastic member 540 and the second elastic member 460 are formed of a tension spring having a predetermined elastic force. Therefore, the right end of the main shaft 420 is protruded to the outside through the right side surface of the housing 300 by the elastic force of the second elastic member 460. When the assembler presses the protruding portion of the main shaft 420 to engage with the hinge device 200, the second elastic member 460 is compressed and the protruding portion is inserted into the housing 300 .

The first elastic member 540 is compressed or expanded according to the axial movement of the guide member 500. The movement of the guide member 500 in the axial direction is performed during the opening / closing process of the cold airflow blocking cover 14.

In detail, the guide member 500 moves to the left or right of the main shaft 420 according to the rotation of the cool airflow blocking cover 14 so that the first elastic member 540 is compressed or elongated. A through hole 501 having the same shape as the end surface of the guide portion 424 constituting a part of the main shaft 420 is formed at the center of the guide member 500. Since the guide portion 424 is formed in a non-circular shape, the guide member 500 can only move in the axial direction along the main shaft 420 and rotate about the main shaft 420 impossible. That is, the guide member 500 can move independently of the main shaft 420 in the direction of the rotation axis of the main shaft 420, but rotates integrally with the main shaft 420 when the guide member 500 is rotated.

A guide protrusion 520 is formed on the outer circumferential surface of the guide member 500. The guide protrusion 520 moves along the raceway groove 380 formed on the inner circumferential surface of the housing 300. The guide protrusions 520 may be formed on the outer circumferential surface of the guide member 500 in two directions opposite to each other. The guide protrusion 520 is protruded by a predetermined length with a diameter corresponding to the width of the raceway groove 380.

The first elastic member 540 is formed to have an inner diameter larger than the outer diameter of the shaft 400 and the second elastic member 460 so as to accommodate both of the shaft 400 and the second elastic member 460.

On the other hand, a raceway groove 380 is formed on an inner circumferential surface of the housing 300 where the guide member 500 is closely contacted, and will be described in detail below with reference to the drawings.

FIG. 7 is a perspective view showing an operation state of a main shaft of a hinge device according to an embodiment of the present invention when the main shaft is inserted into a depression of a cold airflow blocking cover, FIG. 8 is a cross- FIG. 7 is a perspective view showing a state in which the cover is completely inserted.

7 and 8, when the hinge device 200 is fixed to the inside of the temperature regulating device 15, the cool air outflow blocking cover 14 can be rotated with respect to the temperature regulating device 15 The protruding end of the shaft 400, that is, one end of the main shaft 420 is pushed. Then, the second elastic member 460 is compressed and the main shaft 420 is inserted into the housing 300. At the same time, the sub shaft 440 is pushed back and protruded to the outside of the housing 300. In this state, the hinge groove 142 of the cool airflow blocking cover 14 is positioned on the same line as the main shaft 420. When the force for pressing the main shaft 420 is removed, the second elastic member 460 is extended, and one end of the main shaft 420 is inserted into the hinge groove 142 of the chill- . As the second elastic member 460 is extended, the sub shaft 440 is also inserted into the housing 300.

9 is a view showing a movement path of the guide protrusion provided on the guide member of the hinge device in the process of rotating the cold airflow blocking cover according to the embodiment of the present invention.

9, the housing 300 is fixed to the inside of the temperature regulating device 15, and one end of the main shaft 420 is fixed to the hinge groove 142 of the cool air outflow blocking cover 14 . The shaft (400) rotates in accordance with the rotation of the cold airflow blocking cover (14).

In detail, a raceway groove 380 is formed on one side of the inner circumferential surface of the housing 300 constituting the hinge device 200. The orbit groove 380 is formed along the inner circumferential surface of the housing 300 and includes a first guide groove 382 and a second guide groove 384.

The first guide groove 382 guides the guide protrusion 520 when the cold air outflow blocking cover 14 is opened (forward rotation). More specifically, the first guide groove 382 is formed along the inner circumferential surface of the housing 300 in a direction orthogonal to the axial direction of the hinge device 200. The length of the first guide groove 382 is equal to the distance from the cold air outflow blocking cover 14 to the fully opened state. In other words, the first guide groove 382 extends in the circumferential direction along the inner circumferential surface of the housing 300 by a distance that the guide protrusion 520 rotates while the main shaft 420 rotates about 90 degrees do. When the cold airflow blocking cover 14 is closed, the second elastic member 460 and the first elastic member 540 maintain a circular state inside the housing 300. That is, the main shaft 420 and the guide member 500 do not compress the second elastic member 460 and the first elastic member 540, respectively. Further, the guide protrusion 520 is in a position of?. When the cold airflow blocking cover 14 is fully opened, the guide protrusion 520 is positioned at the position (2).

Both ends of the second guide groove 384 are connected to both ends of the first guide groove 382. The second guide groove 384 is a path for guiding the guide protrusion 520 when the cold airflow blocking cover 14 is closed (reverse rotation). In detail, the second guide groove 384 is curved along the inner circumferential surface of the housing 300 so as to protrude in the longitudinal direction of the housing 300. More specifically, the second guide groove 384 extends in the longitudinal direction of the housing 300 from one end of the first guide groove 382, and is bent again to extend to the other end of the first guide groove 382 .

First, when the cold airflow blocking cover 14 rotates in the opening direction, the housing 300 rotates together. Then, the guide protrusion 520 formed on the guide member 500 moves along the first guide groove 382. Here, the guide protrusion 520 rotates together with the main shaft 420 to move along the first guide groove 382, but the guide member 500 maintains a stationary state. In other words, the guide member 500 does not move in the axial direction of the main shaft 420 in this section. Accordingly, the first guide groove 382 may be regarded as a stop section 385 in which the guide member 500 is kept stationary.

A compression section 386 is connected to one end of the stop section 385. The compression section 386 is a section for allowing the guide member 500 to move along the main shaft 420.

In detail, in the compression section 386, the cool airflow blocking cover 14 is closed so that the guide member 500 is rotated together with the main shaft 420 while moving linearly in the axial direction of the main shaft 420 do. The guide member 500 linearly moves to compress the first elastic member 540.

More specifically, the compression section 386 may extend obliquely in the longitudinal direction of the housing 300 at one end of the stop section 385. The guide protrusion 520 of the guide member 500 moves along the compression section 386 of the second guide groove 384. Then, the guide member 500 moves upward (or downward) while rotating together with the main shaft 420. Since the compression section 386 extends in the longitudinal direction of the housing 300, when the guide protrusion 520 moves along the compression section 386, the first elastic member 540 is compressed .

On the other hand, a return section 387 is continued from the end of the compression section 386. The return section 387 is a section for moving the guide member 500 in the reverse direction along the main shaft 420 by the restoring force of the first elastic member 540. That is, in the return period 387, the guide member 500 moves downward (or upward).

The return period 387 extends from the end of the compression section 386 to the other end of the stop section 385 and is connected to the stop section 385. The return section 387 is a section for allowing the guide member 500 to linearly move in a direction in which the first elastic member 540 is extended. When the guide protrusion 520 enters the return section 387, the first elastic member 540 is restored by an elastic force as long as there is no external force to press the first elastic member 540 . At this time, the guide protrusion 520 moves along the return section 387 by the elastic force.

In detail, the return section 387 is curved along the inner circumferential surface of the housing 300 from the end of the compression section 386 to the stop section 385. Therefore, when the guide protrusion 520 reaches the position of (3), it can be closed automatically even if the cold airflow blocking cover 14 is not operated any more. That is, in the process of moving the guide protrusion 520 along the return section 387, the cold air outflow blocking cover 14 is automatically closed in the closing direction without applying any external force to the cold air outflow blocking cover 14 . This is because the guide member 500 can not rotate independently of the main shaft 420 and can only linearly move independently. The guide member 500 moves along the return section 387 in order to move the guide protrusion 520 without departing along the return section 387 due to the restoring force of the first elastic member 540. Therefore, I have no choice but to move. As a result, the guide member 500 moves linearly toward the end of the main shaft 420 while rotating the cooler main shaft 420. Then, the cold airflow blocking cover 14 is automatically rotated in the closing direction.

The orbital groove 380 is formed by connecting the stop section 385 with the compression section 386 and the return section 387. That is, the first guide groove 382 and the second guide groove 384 constituting the raceway groove 380 are formed in a closed loop shape, The guide protrusion 520 can be continuously moved in the orbit groove 380. [

In the drawing, a line h parallel to the central axis of the shaft 400 and passing through the curved portion of the second guide groove 384 is shown as bisecting the first guide groove 382. This means that when the cold airflow blocking cover 14 is opened up to 90 degrees, the guide protrusion 520 is positioned at the curved portion when the cover is rotated in the closing direction by 45 degrees. Accordingly, the interval in which the cool airflow blocking cover 14 is automatically closed may be shortened or elongated depending on the position of the curved portion. For example, if the line h passing through the curved portion is formed closer to the starting point of the compression section 386, the cold air outflow blocking cover 14 is automatically closed when it is rotated in a direction close by 45 degrees or less, If it is formed closer to the end of the section 387, it will automatically be closed after rotating by an angle greater than 45 degrees.

Meanwhile, a latch 390 is further provided on one side of the raceway groove 380. The latch 390 guides the movement path of the guide protrusion 520 so that the guide protrusion 520 can be moved only in one direction within the orbit groove 380. In addition, the guiding protrusions 520 are guided to move along different paths in the process of opening and closing the cold airflow blocking cover 14, respectively.

In other words, in the process of opening the cool air outflow blocking cover 14, the guide protrusion 520 moves along the stopping section 385, and in the process of closing the cool air outflow blocking cover 14, And guided to move along the compression section 386 and the return section 387.

Specifically, the latch 390 is mounted at one end (the left end in FIG. 9) of the first guide groove 382. The latch 390 is configured such that the guide protrusion 520 does not move along the first guide groove 382 again when the cold airflow blocking cover 14 rotates and is closed again (In the direction of the arrow shown in Fig. 9) at the end where the first guide groove 382 ends, so as to move along the second guide groove 384.

The latch 390 is composed of a pivotal lever 392 and a pivot 394 and the pivotal lever 392 is formed to have a length capable of shielding the first guide groove 382, And is axially coupled by a rotation shaft 394 so as to be located at a point deviated inwardly from the rotation shaft 390.

At this time, the latch 390 is configured to rotate only in a direction in which the guide protrusion 520 advances, and when the guide protrusion 520 advances, the first guide groove 382 is opened by a clockwise rotation . After the guide protrusion 520 passes, the first guide groove 382 is returned to its original state by an elastic body (not shown) wound around the rotation shaft 394, thereby shielding the first guide groove 382.

On the other hand, the latch 390 has a step 388 formed on the outer side of the raceway groove 380 so as not to pivot in the opposite direction in the state of shielding the first guide groove 382, So that the rotation can be constrained. It is also possible to suggest various structures for allowing the latch 390 to rotate in only one direction.
