Definitions

  • the present invention relates to a refrigerator including a closure mechanism for biasing a door of the refrigerator into a closed state, wherein the closure mechanism comprises a piston slideable within a housing against the force of a biasing member when the door is opened so that the door closes when released.
  • damping devices which provide the refrigerator doors with a smooth closing operation so as to absorb the shock generated upon closure of the doors.
  • oil filled damping devices have conventionally been used.
  • This kind of damping device however has a problem in that a sealing member thereof can often become worn due to the rectilinear reciprocation of a rod provided in a link mechanism.
  • the link mechanism is horizontally mounted at the bottom of a refrigerator. To achieve the rectilinear reciprocation of the rod, the link mechanism must disadvantageously have long links.
  • damping device requires a separate structure to be used to protect the oil damper as well as the links of the link mechanism.
  • the conventional damping device is generally located 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 mechanism, to repair the damping device, the refrigerator housing has to be laid down on the ground after any contents have been removed, resulting in extreme inconvenience in repair and exchange thereof.
  • the present invention seeks to provide a system which overcomes or substantially alleviates the problems discussed above.
  • a refrigerator according to the present invention is characterised in that the closure mechanism comprises cooperating cam members that translates rotational movement of the door into linear movement of the piston.
  • the closure mechanism comprises a shaft mounted in the housing, one end of the shaft protruding from the housing being connected via a linkage to the door so that the shaft rotates in response to movement of the door between its open and closed state.
  • the cooperating cam members comprise a generally helically formed cam path on the shaft and a cam follower on the piston so that the cam follower follows the cam path when the shaft rotates to cause the piston to slide linearly within the housing.
  • the biasing means is a spring.
  • the piston has a hole therein to receive an elongate guide member fixed to the housing, the guide member sliding within the piston during movement of the piston when the door is opened and closed
  • an aspect of the present invention may provide 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 may 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.
  • FIG. 1 a refrigerator comprising a rectangular housing 1 that is open at a front side thereof, and doors 3 and 4 which are coupled to the housing 1 in a hingedly rotatable manner to allow access to the front side of the refrigerator.
  • a door 3 or 4 is coupled to the housing 1 via a link mechanism 10 provided at an upper or lower end thereof.
  • Damping devices 20 which ensure the smooth opening and closing operations of the doors 3 and 4 are connected to the link mechanism 10. Consequently, the damping devices 20 prevent shock from being applied to the housing 1.
  • equal numbers of damping devices 20 are provided inside each of the doors 3 and 4.
  • the interior of the refrigerator is divided into a left freezing chamber and a right refrigerating chamber which are both designated by reference numeral 2.
  • a plurality of shelves 5 and storage containers 6 to store foods are provided inside the freezing and refrigerating chambers 2.
  • Shelves 7 to store beverages or small containers are provided on the inner surfaces of the doors 3 and 4.
  • the damping devices 20 are provided inside the doors 3 and 4 and each damping device 20 is mounted in a separate mounting space defined in the respective doors 3 and 4 so as to achieve convenience in repair and exchange thereof.
  • a separate mounting space is defined in the lower portion of a front panel of the respective doors 3 and 4, but the position is not limited thereto.
  • the position of the mounting space may be defined in other portions of the doors 3 and 4, or in the housing 1 as the damping device 20 of the present invention encounters substantially fewer spatial problems than a conventional link mechanism, which requires a wide horizontal space.
  • Such a damping device 20 includes a link connecting portion 21 formed at one end which is inserted through a cylindrical guide portion 11a provided on a rectangular plate-shaped support member 11 so as to protrude out of the support member 11 through a centre opening 11b.
  • the support member 11 is further provided with a plurality of bolt fastening holes 11c to enable the fastening of the support member 11 to the door 3 or 4.
  • a first link member 12 is coupled to the link connecting portion 21 which protrudes out of the support member 11.
  • the first link member 12 is bar shaped and has a first hole formed at one end thereof to be used in the coupling of the link connecting portion 21 and a second hole at the other end thereof to be used in the coupling of a second link member 15.
  • the second link member 15 is bar shaped similar to the first link member 12. However, the second link member 15 is longer than the first link member 12. By using fasteners 13, 14 and 16 such as bolts, pins, nuts, etc. one end of the second link member 15 may be coupled to the first link member 12, and the other end of the second link member 15 coupled to a hinge member 17.
  • the first and second link members 12 and 15 are made of a metallic material having strength and durability that is sufficient to endure the load of the refrigerator door.
  • the hinge member 17 is a plate, but the shape is not limited thereto. As such, the hinge member 17 may have other appropriate shapes in consideration of the coupling relationship between the door 3 or 4 and the housing 1. One end of the hinge member 17 is fixed to the refrigerator housing 1 and the other end is fixed to the refrigerator door 3 or 4 by means of a hinge shaft 18. The hinge member 17 has an area that is sufficient to support the load of the refrigerator door.
  • the hinge member 17 is formed with a threaded protrusion 17a to be used in the coupling of the second link member 15 and an opening 17b to enable the coupling of a hinge shaft coupling member 19.
  • the hinge shaft coupling member 19 is fastened to the end of the bottom surface of the door 3 or 4.
  • the hinge member 17 further includes a plurality of threaded holes 17c to allow the hinge member 17 to be firmly fastened to both the refrigerator doors 3 or 4 and the housing 1.
  • the link mechanism 10 comprising the link members is coupled to the damping device 20 as shown in Figure 3.
  • the damping device 20 is mounted inside the door 4 and the support member 11 is bolted to the lower end of the door 4 so that the link connecting portion 21 of the damping device 20 protrudes out of the support member 11 through the centre opening 11b.
  • the first hole of the first link member 12 is fitted to the link connecting portion 21 and held in place by a nut.
  • the second link member 15 is bolted to the first link member 12.
  • the two link members 12 and 15 move according to the opening and closing operations of the refrigerator door. Therefore, in order to relieve the friction that occurs during rotation of the doors 3 or 4 between the first and second link members 12 and 15, a washer is interposed between the first and second link members 12 and 15.
  • the second link member 15 is fixedly coupled to the hinge member 17 wherein one of the holes thereof is fitted around the protrusion 17a of the hinge member 17 and held in place with a nut.
  • the hinge shaft 18 is fitted through the opening 17b of the hinge member 17.
  • the hinge shaft 18 is further fitted in a hinge shaft opening 19a of the hinge shaft coupling member 19 which would have been previously fastened to the end of the bottom surface of the refrigerator door so as to attach the hinge member 17 to the door.
  • the threaded holes 17c of the hinge member 17 are bolted to corresponding holes formed at the refrigerator housing 1 so as to allow the hinge member 17 to be firmly fastened to the refrigerator housing 1.
  • the hinge shaft coupling member 19 having the hinge shaft opening 19a which is provided at the end of the bottom surface of the refrigerator door, simplifies the coupling of the hinge member 17 to the refrigerator door.
  • the damping device 20 comprises a cam member 22 to be inserted into the support member 11.
  • a casing 29 is threaded into the cylindrical guide portion 11a of the support member 11.
  • the link connecting portion 21 of the cam member 22, having an elliptical shape, is inserted through the centre opening 11b of the support member 11.
  • the cam member 22 is inserted into the support member 11 through the link connecting portion 21 provided at one end thereof.
  • the diameter of the cam member 22 is larger than that of the link connection portion 21.
  • Spiral grooves 22a and 22b are formed at the outer periphery of the cam member 22. Both ends of the respective spiral grooves 22a and 22b are rounded and have a diameter larger than that of the remaining portion of the respective spiral grooves 22a and 22b.
  • Rotatably fitted guide pins 23 extend into the spiral grooves 22a and 22b.
  • the guide pins 23 located in the spiral grooves 22a and 22b serve to keep the refrigerator door in completely open and closed positions as well as to secure a smooth damping operation.
  • the diameter of the guide pins 23 is substantially the same as that of the main portion of the respective spiral grooves 22a and 22b to allow the guide pins 23 to smoothly slide along the spiral grooves 22a and 22b.
  • Each of the guide pins 23 has a threaded portion 23a at one end to ensure an easy assembly as well as a pin head at the other end.
  • the threaded portions 23a of the guide pins 23 are screwed into holes 24a that are formed at the lower end region of a piston 24 by passing the threaded portions 23a of the guide pins 23 through the spiral grooves 22a and 22b of the cam member 22.
  • a sealing member 25 is provided around the circumference of the piston 24.
  • the sealing member 25 seals oil that is charged around the piston 24 between the sealing member 25 and a cap member 28.
  • the cap member 28 is located at the distal end of a guide rod 27.
  • the sealing member 25 is formed with a small through-hole 25a to allow the oil to be supplied to the cam member 22 so as to achieve a smooth operation of the cam member 22 and to provide a damping effect.
  • the sealing member 25 also supports a spring 26 which is fitted around the piston 24. To this end, the sealing member 25 is fixedly coupled around the piston 24 so as not to move along the piston 24.
  • the piston 24 is hollow and the guide rod 27 may be inserted into the distal end and allowed to move vertically.
  • the insertion of the guide rod 27 into the piston 24 is possible as the guide rod 27 has a smaller diameter than an inner diameter of the piston 24.
  • the cap member 28 provided at the distal end of the guide rod 27 has a disc shape and contacts with an upper end of the piston 24 according to the motion of the guide rod 27.
  • the cross sectional shapes of the guide rod 27 and the cap member 28 are not perfectly circular and may instead be partially cut-away circles. This, together with corresponding receiving portions in the piston 24 and casing 29 allow the guide rod 27 to linearly move inside the piston 24 without rotating when the cam member 22 is rotated upon an opening of the refrigerator door.
  • the cross sectional shapes of the guide rod 27 and the piston 24 are not limited to partially cut-away circles and may be freely selected from shapes such as square, so long as the shape of the guide rod 27 and the piston 24 prevents rotation.
  • the guide rod 27 and the piston 24 are designed to only linearly move inside the casing 29. Meanwhile, the cam member 22 is designed to rotate around the piston 24.
  • the spring 26 interposed between the guide rod 27 and the piston 24 has a length that is equal to the sum of the length of the guide rod 27 and the length from the upper end of the piston 24 to the sealing member 25 that is fixed around the piston 24. As the cap member 28 vertically moves according to linear motion of the guide rod 27 coupled thereto, the spring 26 contracts or extends.
  • the interior of the casing 29 is charged with the oil in the region of the casing 29 that extends from the sealing member 25 to the cap member 28 when the cap member 28 is coupled to the guide rod 27. Part of the oil is supplied into the cam member 22 along the spiral grooves 22a and 22b by passing through the through-hole 25a formed at the sealing member 25, resulting in smooth controlled driving of the cam member 22.
  • One end of the casing 29 is blocked and the other end is formed with a threaded portion 29a to allow the casing 29 to be securely threaded to the cylindrical guide portion 11 a of the support member 11.
  • Figure 5 illustrates the structure of the link device 10 when the refrigerator door 4 is closed.
  • the first link member 12 and the second link member 15 of the link 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 in a stationary state.
  • Figure 6 illustrates the structure of the link device 10 when the refrigerator door 4 is opened to the right by an angle of 90 degrees compared to Figure 5.
  • the refrigerator door is openable through an angle of approximately 135 degrees.
  • the support member 11 that is fixed to the door 4 is displaced to the right and rotated along with the door 4 and accordingly, a joint portion between the first link member 12 coupled to the support member 11 and the second link member 15 is displaced to the right.
  • the second link member 15 is hingedly rotated in a rotating direction of the door 4.
  • Figure 7 illustrates the damping device 20 when the refrigerator door is closed.
  • the configuration of the damping device 20 is previously explained in the above description in relation with Figure 4.
  • the guide pins 23 are located at the lower ends of the spiral grooves 22a and 22b of the cam member 22.
  • the support member 11 is coupled at the lower end of the damping member 20 so that the link connecting portion 21 is inserted through the support member 11 so as to protrude out of the support member 11.
  • the casing 29 of the damping device 20 is seated in the cylindrical guide portion 11a having a certain height.
  • the cam member 22, the piston 24 and the guide rod 27 are successively inserted inside the casing 29, seated in the support member 11.
  • the spring 26 is interposed between the guide rod 27 and the piston 24.
  • the cam member 22 has a hollow structure so that the piston 24 may be inserted therein.
  • the piston 24 is linearly movable inside the cam member 22 as the guide pins 23 slide along the spiral grooves 22a and 22b of the cam member 22.
  • the sealing member 25 is coupled around the piston 24 at a height that is sufficient to allow the sealing member 25 to be spaced apart from the upper end of the cam member 22 by a certain distance in the lowermost position of the piston 24. As stated above, the sealing member 25 is fixed to the piston 24 to support the spring 26 upon an extension of a contraction of the spring 26. In this way, the sealing member 25 serves not only as an oil sealing member, but also as a spring support member.
  • the guide pins 23 are positioned at the lower ends of the spiral grooves 22a and 22b of the cam member 22.
  • the piston 24, being connected to the guide pins 23 is in the lowermost position inside the hollow cam member 22.
  • the cap member 28 connected to the guide rod 27 is positioned at an upper end of the casing 29 by the elasticity of the spring 26. That is, the spring 26 is in a completely extended state.
  • Figure 8 illustrates the operation of the damping device 20 when the refrigerator door is opened.
  • the link connecting portion 21 which was connected to the refrigerator door so as to protrude out of the support member 11
  • the link members (not shown) connected to the refrigerator door and force the guide pins 23 to slide upward along the spiral grooves 22a and 22b of the cam member 22.
  • the degree of upward movement of the guide pins 23 depends on the degree of opening of the refrigerator door. In a completely opened state, the guide pins 23 are positioned at the upper ends of the spiral grooves 22a and 22b.
  • the present invention includes a feature in that the damping device 20 and the link device 10 connected thereto are mounted at the lower end of the front panel of the door.
  • 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 the link device 10 is simplified. Further, the device may be operable by only two link members.
  • the damping device 20 In a closed state of the refrigerator door, the damping device 20 is in a state as shown in Figure 7 and the link device 10 connected thereto is in a state as shown in Figure 5.
  • the first link member 12 and the second link member 15 are hingedly rotated away from each other.
  • the link connecting portion 21 of the cam member 22 mounted in the door is rotated to cause the guide pins 23, fitted in the lower end of the piston 24 to slide upward along the spiral grooves 22a and 22b of the cam member 22.
  • the piston 24 is moved upward so that the sealing member 25 fixed therearound compresses the spring 26 and the oil, while allowing the guide rod 27 to be inserted therein. Since a rotating angle of the link 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 the spring 26 and the oil are correspondingly variable.
  • the guide pins 23 are positioned at the upper ends of the spiral grooves 22a and 22b.
  • the first and second link members 12 and 15 are rotated toward each other, and the link connecting portion 21 is rotated in an opposite direction to the opening direction of the door.
  • the guide pins 23 are momentarily immobilized, and then slide downward to the lower ends of the spiral grooves 22a and 22b due to their gravity, the restoration force of the spring 26 and the repulsive force of the oil.
  • the damping device of a refrigerator in accordance with the present invention 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.
  • 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.
