Abstract

PURPOSE:To avoid the damage to furniture caused by abutment and the impact thereof against bolts or the like by providing a first operating rod with one end attached to the door and a second operating rod with one end thereof connected with the other end of the first operating rod and the other end thereof pivotally supported by a doorstop member attached to the inner wall of a refrigerating chamber. CONSTITUTION:When a door 5 is made slightly open, first and second operating rods 8 and 9 are extended by a pin 13 with the second operating rod 9 movable slightly outside a refrigerating chamber. An external force is not exerted on the second operating rod 9 for this distance l. Thereafter, the start of engagement of a first gear 14 of the second operating rod 9 with a second gear 17 of a doorstop member 16 occurs, from which time a rotary plate 16b is subjected to the viscous resistance of oil 16c to receive a rotation delaying force so as to make the outward movement of the operating rod 9 sluggish. This alleviates a violent opening of the door 5.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a refrigerator having a front opening/closing door, such as a personal type refrigerator used in a limited space such as a one-room apartment.

BACKGROUND OF THE INVENTION In recent years, personal refrigerators, which are installed in limited spaces such as studio apartments and apartments and adjacent to furniture, are increasingly being used to store beer, juice, and other bottles.

In conventional scale personal type refrigerators, the door opens to the right or to the left, with pivots installed at the top and bottom ends of the refrigerator body, and when the door is opened, the furniture If you try to open the refrigerator without hitting furniture or the like, the opening angle of the opening/closing door is small, making it difficult to take items and bottles in and out of the refrigerator.

On the other hand, there have also been some refrigerators that have a front opening/closing door, as disclosed in Japanese Utility Model Application Publication No. 57-106584.

This type of opening/closing door has a pivot shaft at the bottom of the door, operating rods on both sides of the door, and a support shaft protruding from the wall of the refrigerator compartment to regulate the degree of opening and stop the door. It is something to do. When the door is forcefully opened, the operating rod collides with the support shaft, and the bottles stored on the inner surface of the door may receive a strong impact.

Problems to be Solved by the Invention As mentioned above, in conventional refrigerators, when the door is opened, the bottle that is in contact with the adjacent furniture, etc., and when the door is forcefully opened, the bottle that is stored on the inner surface of the door is Bottles may fall due to impact, or if an open milk bag or the like is stored, the contents may spill out.

The present invention solves the conventional problems, and even if the refrigerator is installed adjacent to furniture etc., when opening the door, the door does not come into contact with the furniture etc., and the degree of opening can be increased.
Moreover, it is an object of the present invention to provide a refrigerator in which, even if the door is forcefully opened, the bottles stored on the inner surface plate of the opening/closing door do not fall over, and the contents do not spill out from opened punctures.

Means for Solving the Problems To achieve this object, the refrigerator of the present invention includes an opening/closing door having a pivot shaft for pivoting a lower side thereof, and a first actuator having one end rotatably attached to the opening/closing door. and a second working stroke, one end of which is rotatably connected to the first working stroke, and the other end of which is rotatably supported by a gradual movement member attached to the wall of the storage chamber. . Further, the gradual movement mechanism includes a first gear attached to the pivot portion of the second operating stroke so as to rotate simultaneously, a rotary plate and a sealed container filled with oil and with the axis of the rotary plate protruding. A second gear is attached to the end of the shaft and meshes with the first gear.

Function The present invention has the above-mentioned structure, whereby the opening/closing door is opened forward by the pivot shaft on the lower side, so that it does not come into contact with adjacent furniture, etc., and the opening/closing door can be forcefully opened. In addition, regardless of the number of bolts, the opening movement of the door is slow, and no impact is applied to the bottles stored on the inner surface of the door, so the contents of opened packs are This prevents spillage to the outside.

Example An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

This will be explained with reference to FIGS. 3 and 4.

Reference numeral 1 denotes a refrigerator main body, which has opening/closing doors 2, 3 on the upper front side for closing the openings of the freezer compartment and the ice-making compartment, and has an opening/closing door 6 on the lower front side for closing the front opening of the refrigerator compartment 4.

The opening/closing door 6 has a pocket 6 on the inner surface plate for storing bottles, etc., and is pivoted to be freely opened and closed in the forward direction by a pivot shaft 7 attached to the lower side of the front opening of the refrigerator compartment 4. has been done. Reference numeral 8 indicates a first actuating mechanism which rotatably pivots one end to both substantially central portions of the opening/closing door 5, and reference numeral 9 attaches one end to a mounting plate 10 on the back side of the front inner wall of the refrigerator compartment 4 with a screw A11. In the second operation stroke, the bag neck (12a) embedded in the mounting base material 12 is rotatably supported by the screw B12b on the mounting base material 12 which is firmly fixed. The other end and the other end of the second operating rod 9 are rotatably connected to the bottle 13.

Further, a first gear 14 is attached to one end of the pivot portion of the second operating rod 9 in the same direction as the rotation of the second operating rod 9.

A slow movement member 16 for slowly rotating the second gear 16 that meshes with the first gear A14 is mounted on the mounting base 12 with a screw C1.
It is installed at 7. As the first gear 14 rotates, it engages with the opening/closing door 6 except for the part that meshes with the second gear 16.
However, when the tooth is closed, 4 teeth are missing. 1
B, IB& are cover plates that cover the mounting base 12, one end of the second operating rod 9, and the first gear 14, and 19 is a cover that covers the mounting screw B17. Moreover, 16a is a closed container, and the oral message board 16b and oil 16G are filled in this container. A rotating shaft 16d of the rotating plate 16b protrudes beyond the closed container 19, and the second gear 15 is fixed to the shaft end.

The operation of the above configuration will be explained.

First, by pressing a button (not shown) on the opening/closing door 6, the third
When opened slightly in the direction of the dashed line from the solid line position in the figure, the first actuating rod 8 and the second actuating rod 9 extend through the bottle 13, and the second actuating rod 9 extends through the bottle 13.
In operation stage 9, there is a slight movement outward from the refrigerator compartment. During these four periods, the first gear 14 and second gear 15 of the opening/closing door 5 do not mesh with each other, so no external force is applied to the second operating rod 9. Thereafter, the first gear 14 of the second working stroke 9 begins to mesh with the second gear 17 of the slow movement member 16. From this point on, rotating plate 1e
b receives the viscous resistance of the oil 16c and begins to receive a force that slows down the rotation. That is, the outward movement of the working stroke 9 is made slow and constant via the first gear 14 and the second gear 16. Furthermore, if the rotating plate 18b rotates faster, the speed of the viscous resistance of the oil 16c will increase, and the force will be large and the rotating speed will be constant. Then, the first gear 14 stops at the stopper 20 position, and the door S is opened and stopped.

As described above, according to this embodiment, the first actuating rod 9
By providing the slow movement member 16 that slowly rotates the second gear 16 that meshes with the gear 14, a buffering force is added to the opening force of the door 5, and the shocking opening of the door 5 is alleviated. The Rukoto.

Since no impact is applied to the bottles stored on the inner surface plate of the opening/closing door, the contents of the opened bottles will not spill out to the outside. Also 4
Conversely, since no force is applied to the door 5 between the two, the door 5 can be opened only by the force of the gasket (not shown) closing the door 5.

Further, the first gear 14 can be made smaller by eliminating teeth other than the part that meshes with the second gear 15 and a part of the size that is small enough to prevent the opening/closing door 6 from being in a closed state. This allows the front part 21 of the mounting base 12 to be made smaller, and the refrigerator compartment 4 can be used more widely.

Effects of the Invention As described above, the present invention has a first working stroke whose one end is rotatably attached to the opening/closing door, one end of which is rotatably connected to the first working stroke, and the other end of which is connected to the inner wall of the storage chamber. and a second working stroke rotatably supported by a slow movement member attached to the second working stroke; A rotary plate, an airtight container filled with oil and with a shaft of the rotary plate protruding, and a second gear that is attached to the end of the shaft and meshes with the first gear, the refrigerator can be used as furniture or the like. Even if the door is installed adjacent to the door, it will not hit the furniture and cause damage when the door is opened, and even if the door is opened forcefully, the bottles stored in the door pocket will not fall over without causing a shock. The contents will not spill out.

Furthermore, it is easy to put bottles in and out of the door pockets.
