Description

  The present invention relates to a refrigerator, and more particularly, to a configuration of an adjustment foot capable of height adjustment.

Generally, the refrigerator has an adjustment foot on the bottom of the refrigerator in order to hold the refrigerator horizontally according to the installation surface. The adjustment foot includes an adjustment foot main body and a screw portion, and is attached to the refrigerator by screwing the screw portion to the bottom surface of the refrigerator. With this structure, the height of the adjustment foot protruding from the bottom surface of the refrigerator can be adjusted by rotating the adjustment foot. Since the height adjustment work is performed after the refrigerator is installed, the weight of the refrigerator is applied to the adjustment foot, and the height adjustment work is performed in a state where the adjustment foot and the installation surface are in contact with each other.
In a conventional refrigerator, a through hole or a through groove is provided in the adjustment foot body, and a long tool such as a screwdriver is inserted there, and the screw is engaged with the hole or groove to apply force to the gripping portion of the tool. The height was adjusted accordingly. By doing so, it is possible to reduce the force required to rotate the adjustment foot, compared to the case where the outer periphery of the adjustment foot body is gripped and rotated by hand. Thereby, height adjustment work can be easily performed (for example, refer patent document 1).

The support leg member 81 shown in FIG. 6 is made of sheet metal, and is fixed to the bottom surface of the refrigerator housing with a screw. At that time, the adjusting foot 6 is located in front of the opening end face of the refrigerator housing 1 and below the door 32 of the vegetable compartment. Even if the center of gravity of the refrigerator is placed forward when the refrigerator door is opened, the refrigerator is disposed so as not to fall forward.

6 is a perspective view of the supporting leg 4 of the refrigerator shown in FIG. 1 as viewed from the upper surface side with the adjusting foot 6 removed from the supporting leg 4, and FIG. 7 is a perspective view of the supporting leg 4 of FIG. FIG.
The adjustment foot 6 is composed of, for example, a resin adjustment foot main body 80 and a screw portion 5. The adjustment foot main body 80 has a cylindrical shape, and has a circular shape with a diameter of, for example, about 45 mm when viewed from above. The adjustment foot 6 includes a screw portion 5 protruding from the upper surface side of the circular center portion of the adjustment foot main body 80, and the screw portion 5 is screwed into a nut portion 82 welded to the support leg member 81 to thereby reduce the refrigerator. It can be moved up and down. The screw portion 5 protruding from the adjustment foot upper portion 88 has a central axis perpendicular to the adjustment foot bottom portion 87, and is fixed to a resin adjustment foot main body 80 by integral molding, for example. The threaded portion 5 includes a threaded portion 5a, a flange-shaped portion 5b, and a shaft portion 5c before being integrally formed with the adjusting foot main body 80. When the screw portion 5 is integrated with the adjustment foot main body 80, the flange-shaped portion 5b and the shaft portion 5c are embedded in the adjustment foot main body (see FIG. 10).

  The adjustment sole 87 comes in contact with the installation surface of the refrigerator and supports the weight of the refrigerator. When installing the refrigerator, the installation contractor or the user of the refrigerator can adjust the height of the adjustment foot 6 from the support leg 4 by grasping and rotating the circular adjustment foot side portion 86 of the adjustment foot 6, The refrigerator can be installed horizontally according to the state of the refrigerator installation surface. The adjustment foot side portion 86 is provided with a concavo-convex shape extending in a direction perpendicular to the adjustment foot bottom portion 87 so that a finger of a user or the like is not easily slipped when the outer periphery of the adjustment foot 6 is grasped. Further, the adjustment foot 6 is provided with four tool engaging portions 83 having openings in the adjustment foot side portion 86, and it is difficult to rotate the gripping foot portion 86 with a hand or the like. In some cases, a tool can be inserted and rotated.

8 is a front view of the adjustment foot 6 attached to the support leg 4, and FIG. 9 is a side view of FIG. FIG. 10 is a diagram showing a cross section of the ZZ portion of FIG. 8, and shows a cross sectional view in a state where the adjusting foot 6 is attached to the support leg 4.
The adjustment foot 6 is provided with four tool engaging portions 83 radially around the screw portion 5. For example, the tool engaging portion 83 has a width in which a rod-shaped object having a diameter of about 6 mm can be inserted. For example, the tool engaging portion 83 serves as a working hole for inserting a generally sold driver from the outer peripheral side of the adjusting foot 6 substantially horizontally. It is possible to use.
A large torque can be applied to the adjusting foot 6 by inserting, for example, a screwdriver into the tool engaging portion 83 and applying a load to the gripping portion of the driver in the direction in which the adjusting foot 6 rotates. Depending on the state of the installation surface of the refrigerator, the friction force between the bottom surface of the adjustment foot 6 and the installation surface is high, and it may be difficult to grasp and rotate the outer periphery of the adjustment foot 6. Further, as the size of the refrigerator increases, the weight of the refrigerator increases, and the friction force between the adjustment sole 87 and the installation surface may increase due to the weight of the refrigerator. In such a case, it is possible to easily adjust the height by rotating the adjusting foot 6 using a familiar tool possessed by the refrigerator installer or the user of the refrigerator. Can be installed.

  The tool engagement portion 83 is formed from the outer periphery of the adjustment foot 6 toward the screw portion 5. The outer peripheral surface of the adjustment foot 6 is used as the start end of the tool engagement portion 83, and the screw portion 5 of the adjustment foot 6 is embedded therein. The end of the tool engaging portion 83 is the point before reaching the portion. With this configuration, the portion embedded in the adjustment foot main body of the screw portion 5 (for example, the flange-shaped portion 5b and the shaft portion 5c) and the tool engagement portion 83 do not overlap in the height direction of the adjustment foot 6. The height of the adjusting foot 6 can be reduced. Therefore, the height adjustment operation can be easily performed using a commercially available tool or the like without reducing the internal volume of the refrigerator by the adjustment foot 6.

  Further, for example, about 10 mm from the outer periphery of the tool engaging portion 83 according to the present embodiment is an upper groove 84 having a groove shape with the upper side opened. For example, about 5 mm in the vicinity of the center of the adjustment foot 6 in the tool engaging portion 83 is a bottom hole 85 whose lower side is opened, and there is a resin on the upper side of the adjustment foot 6 and a hole in the lower side. . When viewed from the adjustment foot upper portion 88 side, the upper groove 84 and the bottom hole 85 are arranged such that the center line of the upper groove 84 and the center line of the bottom hole 85 are on the same straight line or substantially the same straight line. The hole 85 communicates with each other. When the tool engaging portion 83 is viewed from the outer peripheral side of the side surface of the adjustment foot main body 80 toward the center, the hole 85 has a size that allows the tool to be inserted (see FIG. 8). . The wall surfaces forming the groove side surfaces of the upper groove 84 and the bottom hole 85 are connected to form a continuous surface. However, as long as a tool can be inserted and a force can be applied, a case where there is a step between the wall surface of the upper groove 84 and the wall surface of the bottom hole 85 is acceptable, for example, due to processing convenience. When a tool is inserted into the tool engaging portion 83 and a load is applied in the rotational direction of the screw portion 5, the tool and the wall surface come into contact with each other at two points. The applied force is applied from two contact points between the tool and the wall surface, and the adjustment foot 6 can be easily rotated.

  Further, there is a portion where the upper groove 84 which is a portion opened to the upper side of the tool engaging portion 83 and the bottom hole 85 which is a portion opened to the lower side overlap each other. A portion where the portion opened to the upper side of the upper groove 84 and the portion opened to the lower side of the bottom hole 85 overlap is a hole portion 89 (see FIG. 10) penetrating in the vertical direction of the adjustment foot 6. .

Below, the effect that the tool engaging part 83 which concerns on this Embodiment is provided with the top groove | channel 84 and the bottom hole 85 is demonstrated.
When the tool engaging portion 83 is formed only by the upper groove 84, there is no portion for receiving the tool on the upper side. It is difficult to apply a force in the direction of rotation, and it is not suitable for adjustment work. By making the dimension of the depth direction of the upper groove 84 larger than the diameter of the tool to be inserted, it is possible to make it difficult for the tool to come out of the groove. This will cause a loss in the internal volume.
Moreover, when the tool engaging part 83 is formed only by the groove | channel which existed in the bottom face side, it is necessary to insert the front-end | tip part of a tool in the tool engaging part 83 along the installation surface of a refrigerator. In general, the gripping part of the tool is thicker than the tip, so when inserting the tool tip into the tool engagement part 83, the tool is engaged with the tool tip inclined toward the installation surface. It is necessary to insert into the part 83. If the depth direction dimension of the groove opened on the bottom side is deeper than the radius of the gripping part of the tool, the tool can be inserted horizontally with the installation surface, but the depth of the groove opened by the operator on the bottom side can be reduced. When only a tool having a large radius of the tool grip portion relative to the vertical dimension is held, it is difficult to insert the tool into the groove. Moreover, if the depth dimension of the groove opened on the bottom surface side is determined in consideration of the gripping part dimensions of many types of tools, the height of the adjustment foot 6 becomes large, causing a loss in the internal volume of the refrigerator. It will be.
On the other hand, in the tool engaging portion 83 of the adjustment foot 6 of the refrigerator according to the present embodiment, the tool tip side has a resin wall 90 on the upper surface side of the adjustment foot 6, and the wall 90 on the adjustment foot upper side is inserted. In order to limit the movement of the tool tip, the tool tip is unlikely to come off the groove during work. The gripping portion side of the tool inserted into the tool engaging portion 83 has a wall 91 on the bottom surface side of the adjustment foot 6 and opens on the upper surface side of the adjustment foot 6, so that the tool is centered from the outer peripheral side of the adjustment foot 6. It is possible to insert diagonally from the upper surface side of the adjustment foot 6 with the tool tip directed toward the installation surface. This makes it easy to insert the tool into the tool engaging portion 83 even when the outer diameter dimension of the tool gripping portion is thicker than the tool tip, and the tool selection is performed when the adjustment foot 6 is rotated. The width of.

  Further, if dust or the like enters the tool engaging portion 83, it falls down from the bottom hole 85, so that dust or the like is difficult to collect in the tool engaging portion 83. Since it can be dropped from the bottom hole 85 by pushing into the center side of the joint part 83, the removal is also easy.

  In addition, the tool engaging portion 83 can be configured without the hole 89 penetrating the adjustment foot 6 in the vertical direction. However, the presence of the hole 89 allows the undercut to be formed in the shape of the resin molding portion of the adjustment foot main body 80. Since there is no portion, there is an advantage that a mold structure for resin molding can be simplified. In addition, there is an advantage that processing can be easily performed even when manufacturing by machining.

  The tool engaging portion 83 closes the upper groove 84 by the wall 90 on the upper side of the adjustment foot, and moves from the adjustment foot side portion 86 provided with an opening in the adjustment foot side portion 86 toward the screw portion 5 of the adjustment foot 6. The extending lateral hole and the bottom hole 85 may be communicated with each other. Further, the tool engaging portion 83 may be configured to communicate from the outer peripheral side of the adjusting foot 6 in the order of the lateral hole opened to the adjusting foot side portion 86, the upper groove 84, and the bottom hole 85. Even in these configurations, the above-described dust and the like are not easily collected, and the effect of easily removing the dust can be obtained.
