Description

Description: TECHNICAL FIELD The present invention relates to a refrigerator having a personal type front opening / closing door used in a limited space such as a studio apartment or an office.

2. Description of the Related Art In recent years, personal refrigerators installed in confined spaces such as studio apartments and offices and adjacent to furniture and the like frequently use bottles such as beer and juice.

Conventionally, in the refrigerator of this type of personal type,
The opening and closing door adopts a right-opening or left-opening method in which a pivot portion is provided at the upper and lower ends of the refrigerator main body.When the opening and closing door is opened, it collides with furniture or the like and damages it.
If the door is opened without touching furniture or the like, the opening degree of the opening / closing door is reduced, and it is difficult to take in and out food and bottles in the storage room.

On the other hand, a refrigerator having a front opening / closing door as in Japanese Utility Model Laid-Open Publication No. 57-105584 has also been found.

In this type of opening / closing door, a pivot shaft is provided on the lower side of the door, and an operating rod provided on both sides of the door and a supporting shaft protruding from the wall surface of the storage chamber regulate the degree of opening and stop the door. Is what you do. When the refrigerator is actually used, food and bottles stored in the storage room are taken in and out while the door is opened and stopped. Therefore, when the door is strongly opened, the operating rod may strongly collide with the support shaft, or when the end of the opened door is put on a hand, a large load may be applied to the support shaft portion.

PROBLEM TO BE SOLVED BY THE INVENTION As described above, in the conventional refrigerator, when the door is opened, it collides with adjacent furniture to damage it, the door is strongly opened, or a hand is placed on the end of the opened door. If it is applied, there is a drawback that an excessive load is applied to the support shaft to cause deformation and breakage.

The present invention is to solve the conventional problems, even if the refrigerator is installed adjacent to furniture and the like, when opening the opening and closing door can be opened and closed slowly without colliding with furniture etc. It is an object of the present invention to provide a refrigerator that does not impair the slow-moving function even when a large force is applied to the door end.

Means for Solving the Problems In order to achieve this object, a refrigerator according to the present invention comprises an opening / closing door having a pivot shaft pivotally supported on a lower side, and one end rotatable substantially at the center of the opening / closing door. A first operating rod pivotally supported by the first operating rod; a second operating rod pivotally supported at the other end and one end of the first operating rod rotatably at the other end on the wall surface of the storage chamber; The other end of each of the first operating rod and the second operating rod is rotatably connected to each other, and the gear A attached to the pivotal support of the second operating rod is engaged with the gear A and connected to the slow-moving member. A gear B is provided, and the position of the pivot portion to which the gear A is attached is positioned closer to the opening / closing door than the position of the slow-moving member.

Effect of the Invention According to the above configuration, the opening and closing door is opened forward by the pivot on the lower side so that it does not collide with adjacent furniture and the like, and even if the opening and closing door is strongly opened, immediately before the stop of the opening and closing door. The opening movement is slow, and even if a large force is applied to the door end, an excessive load is not applied to the slow-moving member, thereby causing no deformation and destruction, so that the slow-moving function is not impaired.

Embodiment An embodiment of the present invention will be described below with reference to FIGS.
This will be described with reference to FIGS.

Reference numeral 1 denotes a refrigerator body, which has closing doors 2 and 3 for closing openings of a freezing room and an ice making room on an upper front surface and an opening / closing door 5 for closing a front opening portion of a refrigerator compartment 4 on a lower front surface. The door 5
Has a pocket 6 for storing bottles and the like on the inner surface plate,
The refrigerating compartment 4 is pivotally supported to be openable and closable in a forward direction by a pivot 7 attached to the lower side of the front opening. Reference numeral 8 denotes a first operating rod having one end rotatably pivoted at substantially the center both sides of the opening / closing door 5, and 9 has one end attached to a mounting plate 10 on the back surface of the inner wall front surface of the refrigerator compartment 4 by means of a screw A 11. A second operating rod pivotally supported on the fixed mounting base material 12,
The other end of the first operating rod 8 and the other end of the second operating rod 9 are rotatably connected by a connecting pin 13. Further, a gear A15 is provided on one end pivot 14 of the second operating rod 9.
It is fixed so that it works together.

A screw B18 is attached to and fixed to the mounting base 12 so as to interlock with a slow-moving member 17 for slowly rotating a gear B16 meshing with the gear A15. At this time pivot 14
Is located at the front of the mounting base 12 and closer to the opening / closing door 5, and the slow-moving member 17 is positioned at the rear of the mounting base 12.
Reference numeral 19 denotes a slow-moving member cover, which covers the slow-moving member 17, the gear B16, and the like. Reference numeral 20 denotes an operating rod cover, and the second operating rod 9
It covers 14 branches and so on.

 The operation of the above configuration will be described.

First, when the opening and closing door 5 is slightly opened from the solid line position in FIG. 2 by a push button operation (not shown) or the like, the first operating rod 8 and the second operating rod 9 extend through the connecting pin 13. The second operating rod 9 moves slightly outward from the refrigerator compartment. Thereafter, the gear A14 of the second operating rod 9 meshes with the gear B17 to rotate the slow-moving member 16, and moves while being reduced to a constant speed by the rotating torque generated at this time. Thereafter, the door 5 is moved to a predetermined angle and stopped, and the opening of the door 5 is completed. At this time, foods and the like stored in the vehicle can be taken in and out, but a large load such as weight may be applied by putting a hand on the tip of the opening / closing door 5 during the operation. In such a case, the load applied to the front end of the door 5 exerts a force in the direction of pulling the first operating rod 8 and the second operating rod 9 toward the door, and both the pivot 14 and the gear A15 are moved toward the door. Therefore, the gear A15 and the gear B16 move away from each other so that their gears are disengaged. That is, the moving member 16 is isolated from the load applied to the front end of the opening / closing door 5, and is not affected by the load.

Effect of the Invention As described above, the present invention provides a first operating rod that pivotally supports one end at a substantially central side of an opening / closing door that rotates about a lower side, and the other end of the first operating rod. A second operating rod having one end rotatably supported and the other end pivotally supported on the wall surface of the storage chamber; and the other end of each of the first operating rod and the second operating rod rotatably. Since the position of the pivot portion of the second operating rod is located closer to the opening / closing door than the position of the slow-moving member, when the door is opened, it does not collide with and damage adjacent furniture. It can be opened and closed, and even if the door is opened strongly or the end of the opened door is put on, the excessive force will not be applied to the slow motion member, and it will not break or damage, so the slow motion function will not be impaired It can provide a stable, safe product of a quality that can always operate at a slow speed.
