Abstract
A refrigerator comprising a housing, a pair of doors, link devices, and damping devices. Each of the damping devices includes a casing defining the appearance of the damping device, a cam member, a piston, a sealing member fitted around the piston, a spring, a guide rod, and a cap member connected to the guide rod so as to be positioned inside the casing. Since the damping device of the present invention is reducible in size, and is vertically mountable by virtue of its reduced operating space, it can be installed inside a refrigerator door or refrigerator housing, rather than the bottom surface of the refrigerator. Especially, the damping device can be mounted inside the lower end portion of a front panel of the refrigerator door, resulting in ease in exchange and repair thereof.
Description
- This application claims the benefit of Korean Patent Application No. 2004-36260, filed on May 21, 2004 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to a refrigerator, and, more particularly, to a damping device of a refrigerator which reduces an operating space thereof, and a simplified link device to realize the damping device.
- 2. Description of the Related Art
- Generally, in order to protect a refrigerator as well as various foods stored therein, the refrigerator is provided with damping devices, which serve to absorb shock generated upon a closing of refrigerator doors so as to secure a smooth closing operation of the doors. As such, a damping device has conventionally been a device using oil. This kind of damping device, however, has a problem in that a sealing member thereof is often worn due to rectilinear reciprocation of a rod provided in a link device of the damper. Here, the link device is horizontally mounted at the bottom of a refrigerator. To achieve the rectilinear reciprocation of the rod, the link device must have disadvantageously long links.
- Another problem of the conventional damping device is that the damping device requires a separate structure to be used in the protection of an oil damper as well as the links of the link device.
- In such a conventional damping structure of refrigerator doors as stated above, further, since the links of the link device tend to bend due to an external force applied to the refrigerator door, there exists the need for a wide operating space to avoid interference of the links.
- In most cases, furthermore, since the conventional damping device is provided at the bottom of a refrigerator housing so that the conventional damping device connects the refrigerator housing to a refrigerator door by cooperating with the link device, to repair of the damping device, the refrigerator housing has to be laid down on the ground after all foods therein are taken out, resulting in extreme trouble in repair and exchange thereof.
- Therefore, an aspect of the present invention provides a refrigerator comprising a damping device of a refrigerator door, which is mountable even in a narrow space by virtue of a reduced operating space of the damping device, and a simplified link device, which enables the damping device to be mounted to the refrigerator door without interference of other members.
- Another aspect of the invention is to provide a refrigerator comprising a damping device, which is designed to be mounted in a separate space defined in a refrigerator door, resulting in simplicity in repair and exchange thereof.
- Accordingly, the present invention provides a refrigerator comprising a housing, and a pair of doors coupled to the housing in a hingedly rotatable manner, and further comprising: link devices to be used in the transmission of a rotating force of the doors relative to the housing; damping devices, each of which is coupled to one end of the respective link devices, to absorb shock applied to the doors, and/or to allow the doors to be automatically closed.
- Each of the damping devices may include: a casing to define the appearance of the damping device; a cam member to convert a rotating motion of an associated one of the doors into a linear motion thereof: a piston coupled to the cam member inside the casing so as to linearly move; and oil charged inside the casing to exert damping operation through a volume constriction or expansion thereof, which is caused by the linear motion of the piston.
- The damping device may be mounted in a separate mounting space that is vertically defined inside the door.
- The cam member of the damping device may take the form of a hollow shaft having spiral grooves, and the piston may be coupled to the cam member so as to linearly move along the spiral grooves. As a result, the cam member may serve to convert the rotating motion of the door, transmitted through an associated one of the link devices, to the linear motion of the piston.
- The cam member may be positioned inside the cylindrical casing so that a link connecting portion that is provided at one end thereof protrudes outwardly to allow the link device to be rotatably fitted therearound.
- The damping device may further include a sealing member, which is fixed around the piston to seal the oil charged around the piston inserted inside the casing.
- The cam member and the piston may be coupled to each other by means of guide pins so that the piston is linearly movable within a range of the spiral grooves formed at the cam member.
- The guide pins may be located close to a lower end of the cam member in a closed state of the door, and slide upward along the spiral grooves toward an upper end of the cam member by receiving an external force when the door is opened, so as to allow the oil to be compressed by a sealing member. As a result, the guide pins may serve to allow the door to be smoothly closed or be automatically closed as they are returned toward the lower end of the cam member by making use of a repulsive force of the oil.
- Further, the present invention also provides a refrigerator comprising a housing, and a pair of doors coupled to the housing in a hingedly rotatable manner, and further comprising: damping devices provided at the doors or the housing; and link devices to connect the housing and the respective doors in order to transmit a rotating force of the doors to the damping devices.
- Each of the link devices may include a first link member and a second link member.
- Each of the first and second link members may have rotatably connectable joint portions at both ends thereof.
- The first and second link members may partially overlap each other while forming a small angle therebetween in a closed state of an associated one of the doors, whereas they may be spaced apart from each other by a certain large angle when the door is opened.
- Fasteners to rotatably connect the first and second link members to each other may be coupled to respective joint portions.
- The link device may be positioned adjacent to a center axis of rotation of an associated one of the doors relative to the housing.
- The link device may include a hinge member and a hinge shaft, and one end of the hinge member is fixed to the housing, and the other end of the hinge member is coupled to associated one of the doors by means of the hinge shaft so as to secure rotation of the door.
- Additional and/or other aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

FIG. 4 is an exploded perspective view illustrating the structure of the dampingdevice 20 in accordance with the present invention. - Referring to
FIG. 4 , the dampingdevice 20 comprises acam member 22 to be coupled to thesupport member 11. Acasing 29 is threaded into thecylindrical guide portion 11 a of thesupport member 11. Thelink connecting portion 21 of thecam member 22, having an elliptical shape, is inserted through the center opening 11 b of thesupport member 11. As a result, the motion of the link members, which are coupled to thesupport member 11, is transmitted to thecam member 22 to induce the operation of the dampingdevice 20 in correspondence to the opening and closing operations of the refrigerator door. - The
cam member 22 is coupled to thesupport member 11 through thelink connecting portion 21 provided at one end thereof. The diameter of thecam member 22 is larger than that of thelink connecting portion 21.Spiral grooves cam member 22. Both ends of therespective spiral grooves respective spiral grooves - Rotatably fitted guide pins 23 extend through the one-side ends of the
spiral grooves respective spiral grooves spiral grooves - Each of the guide pins 23 has a threaded
portion 23 a at one end thereof to secure an easy assembly thereof, as well as a pin head at the other end thereof. Where apiston 24 is inserted in thecam member 22, the threadedportions 23 a of the guide pins 23 are fitted in twocoupling holes 24 a that are formed at the lower end region of apiston 24 by passing the threadedportions 23 a of the guide pins through thespiral grooves cam member 22. - A sealing
member 25 is provided around the circumference of thepiston 24. The sealingmember 25 seals oil that is charged around thepiston 24 between the sealingmember 25 and acap member 28. Thecap member 28 is located at the distal end of aguide rod 27. The sealingmember 25 is formed with a small through-hole 25 a to allow the oil to be supplied to thecam member 22 so as to achieve a smooth operation of thecam member 22. The sealingmember 25 also supports aspring 26, which is fitted around thepiston 24. To this end, the sealingmember 25 is fixedly coupled around thepiston 24 so as not to move along thepiston 24. - The
piston 24 is hollow, and theguide rod 27 may be inserted therein in a vertically movable manner. The insertion of theguide rod 27 into thepiston 24 is possible because theguide rod 27 has a diameter that is smaller than an inner diameter of thepiston 24. Thecap member 28, provided at the distal end of theguide rod 27, has a disk shape, and contacts with an upper end of thepiston 24 according to the motion of theguide rod 27. - The cross-sectional shapes of the
guide rod 27 and thecap member 28 are not perfectly circular, and may instead be partially cut-away circles. Such a shape is effective to allow theguide rod 27 to linearly move inside thepiston 24 without rotation when thecam member 22 is rotated upon an opening of the refrigerator door. Of course, the cross sectional shapes of theguide rod 27 and thepiston 24 are not limited to partially cut-away circles and may be freely selected from among a square and other shapes so long as the shaped of theguide rod 27 and thepiston 24 may prevent rotation of theguide rod 27. - That is, the
guide rod 27 and thepiston 24 are designed to only linearly move inside thecasing 29. Meanwhile, thecam member 22 is designed to rotate around thepiston 24. - The
spring 26, interposed between theguide rod 27 and thepiston 24, has a length that is equal to the sum of the length of theguide rod 27 and the length from the upper end of thepiston 24 to the sealingmember 25 that is fixed around thepiston 24. As thecap member 28 vertically moves according to linear motion of theguide rod 27 coupled thereto, thespring 26 contracts or extends. - The interior of the
casing 29 is charged with the oil in he region of thecasing 29 that extends from the sealingmember 25 to thecap member 28 when thecap member 28 is coupled to theguide rod 27. Part of the oil is supplied into thecam member 22 along thespiral grooves hole 25 a formed at the sealingmember 25, resulting in smooth driving of thecam member 22. One end of thecasing 29 is blocked, and the other end thereof is formed with a threadedportion 29 a to allow thecasing 29 to be threaded to thecylindrical guide portion 11 a of thesupport member 11. -
FIG. 5 is a front view to illustrate the structure of thelink device 10 in accordance with the present invention, in a state in which therefrigerator door 4 is closed. In such a state, thefirst link member 12 and thesecond link member 15 of thelink device 10 are angled with respect to each other rather than completely overlapped. Such an arrangement is effective to support the load of the refrigerator door in rotation as well as a stationary state. -
FIG. 6 is a front view to illustrate the structure of thelink device 10 in accordance with the present invention, in a state in which therefrigerator door 4 is opened to the right by an angle of 90 degrees compared toFIG. 5 . In general, the refrigerator door is openable through an angle of approximately 135 degrees. - As the
refrigerator door 4 is opened, thesupport member 11 that is fixed to thedoor 4 is displaced to the right and rotated along with thedoor 4, and accordingly, a joint portion between thefirst link member 12 coupled to thesupport member 11 and thesecond link member 15 is displaced to the right. Thereby, thesecond link member 15 is hingedly rotated in a rotating direction of thedoor 4. - Upon opening the
door 4, thelink connecting portion 21, which was rotatably mounted to thedoor 4, is rotated. Such a rotation of thelink connecting portion 21 is converted into linear motion of thepiston 24 by thecam member 22. -
FIG. 7 is a sectional view to illustrate the operation of the dampingdevice 20 in accordance with the present invention, in a state in which the refrigerator door is closed. The configuration of the dampingdevice 20 is previously explained in the above description in relation withFIG. 4 . In a closed state of the door, the guide pins 23 are located at the lower ends of thespiral grooves cam member 22. - The
support member 11 is coupled at the lower end of the dampingmember 20 so that thelink connecting portion 21 is inserted through thesupport member 11 so as to protrude out of thesupport member 11. In this case, thecasing 29 of the dampingdevice 20 is seated in thecylindrical guide portion 11 a having a certain height. - The
cam member 22, thepiston 24, and theguide rod 27 are successively inserted inside thecasing 29, seated in thesupport member 11. Thespring 26 is interposed between theguide rod 27 and thepiston 24. Thecam member 22 has a hollow structure so that thepiston 24 may be inserted therein. Thepiston 24 is linearly movable inside thecam member 22 as the guide pins 23 slide along thespiral grooves cam member 22. - The sealing
member 25 is coupled around thepiston 24 at a height that is sufficient to allow the sealingmember 25 to be spaced apart from the upper end of thecam member 22 by a certain distance in the lowermost position of thepiston 24. As stated above, the sealingmember 25 is fixed to thepiston 24 to support thespring 26 upon an extension or a contraction of thespring 26. In this way, the sealingmember 25 serves not only as an oil sealing member, but also as a spring support member. - In a closed state of the refrigerator door, the guide pins 23 are positioned at the lower ends of the
spiral grooves cam member 22. Thus, thepiston 24, being connected to the guide pins 23, is in the lowermost position inside thehollow cam member 22. In this case, since no pressure is applied to theguide rod 27, thecap member 28 connected to theguide rod 27 is positioned at an upper end of thecasing 29 by the elasticity of thespring 26. That is, thespring 26 is in a completely extended state. -
FIG. 8 is a sectional view to illustrate the operation of the dampingdevice 20 in accordance with the present invention, in a state in which the refrigerator door is opened. Where the refrigerator door is opened by receiving an external force, thelink connecting portion 21, which was connected to the refrigerator door so as to protrude out of thesupport member 11, is rotated by the link members (not shown) connected to the refrigerator door to force the guide pins 23 to slide upward along thespiral grooves cam member 22. Such an upward movement degree of the guide pins 23 depends on the opening degree of the refrigerator door. In a completely opened state of the refrigerator door, the guide pins 23 are positioned at the upper ends of thespiral grooves - As a result, the
piston 24, which was coupled to the guide pins 23 so as to vertically move inside thecam member 22, compresses the oil and thespring 26 by making use of the sealingmember 25 sealably coupled around thepiston 24. Since the oil and thespring 26 have a tendency to restore their original states by their shock absorbing and elastic properties, the door may be smoothly closed, and may automatically close when the door is opened within a range that is not more than a predetermined angle. - When the refrigerator door is closed, a force, applied to the guide pins 23, is released. Thus, the guide pins 23 slide downward along the
spiral grooves spring 26. As a result, the guide pins 23 become seated in the lower ends of thespiral grooves FIG. 7 . In this case, even if the refrigerator door is closed with an extremely strong external force, the resulting shock may be absorbed by theelastic spring 26 and the oil charged in thecasing 29. As a further result, since the guide pins 23 slowly slide downward along thespiral grooves spring 26 and a repulsive force of the oil against the volume constriction thereof, thelink connecting portion 21 connected thereto is accordingly slowly rotated, the refrigerator door is smoothly closed. - Now, the operation and effects of the preferred embodiment of the present invention will be explained in detail. The present invention includes a feature in that the damping
device 20 and thelink device 10 connected thereto are mounted at the lower end of the front panel of the door. - Different from the conventional damping device and by virtue of a reduced operating space, the damping
device 20 may be mounted vertically inside the refrigerator door or the refrigerator housing within a narrow space, without requiring to be horizontally installed along the lower end of the housing 1. In this way, the overall structure of thelink device 10 is simplified. Further, the device may be sufficiently operable by only two link members. - Now, the rotation of the damping
device 20 using thehinge member 17 will be explained in detail. - In a closed state of the refrigerator door, the damping
device 20 is in a state as shown inFIG. 7 , and thelink device 10 connected thereto is in a state as shown inFIG. 5 . If an external force causes the door to be opened, thefirst link member 12 and thesecond link member 15 are hingedly rotated so that they are spaced apart from each other. Thus thelink connecting portion 21 of thecam member 22 mounted in the door is rotated to cause the guide pins 23, fitted in the lower end of thepiston 24, to slide upward along thespiral grooves cam member 22. As a result, thepiston 24 is moved upward so that the sealingmember 25 fixed therearound compresses thespring 26 and the oil, while allowing theguide rod 27 to be inserted therein. Since a rotating angle of thelink connecting portion 21 is variable according to an opening angle of the door, the position of the guide pins 23 as well as the compression of thespring 26 and the oil are correspondingly variable. - When the door begins to close again, the guide pins 23 are positioned at the upper ends of the
spiral grooves second link members link connecting portion 21 is rotated in an opposite direction of the opening direction of the door. At the moment when thelink connecting portion 21 begins to rotate, the guide pins 23 are momentarily immobilized, and then slide downward to the lower ends of thespiral grooves spring 26, and the repulsive force of the oil. - Even if a relatively strong external force closes the door, the
spring 26 and the oil are slowly returned to their original states, resulting in damping effect. - As is apparent from the above description, since the damping device of a refrigerator in accordance with the present invention is reduced in size, and is vertically mountable by virtue of the reduced operating space thereof, the damping device may be installed inside a refrigerator door or refrigerator housing, rather than the bottom surface of the refrigerator. Further, the damping device may be mounted inside the lower end portion of a front panel of the refrigerator door, resulting in an ease of an exchange and repair thereof.
- Further, according to the present invention, the damping device may reduce the number of elements and the volume of a space required for the installation of a link device, resulting in enhancement in simplicity and easy assembly of the link device.
- 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.
