However, in the door piece structure of Patent Document 1, since the link of the support arm must be provided at the upper and lower end portions of the spacer body, the structure is complicated and the cost is high. In the door piece structure of Patent Document 2, it is necessary to provide a guide having a guide groove on the upper and lower sides of the main body opening portion, so that the structure is complicated and the cost is high. In the door piece structure of Patent Document 3, since the guide pin is of a fixed type, there is a possibility that the position of the guide pin and the guide groove are shifted, and when the position is displaced, the opening and closing force of the door piece may be deteriorated. , causing problems such as the door being half open.

On the other hand, in the mechanism for the cold air leakage countermeasure of the right and left split door panels, as shown in Patent Document 3, the guide pins are fixed. Therefore, the positional relationship between the guide groove at the end of the separator body and the guide pin on the body side must be strictly set. When the position of the guide pin or the guide groove is seriously staggered in the left-right direction of the refrigerator, the guide pin cannot be inserted into the guide groove, and in the worst case, the guide pin becomes unrelated to the guide groove (falling). In addition, when the position of the guide pin or the guide groove is slightly shifted, the contact angle of the guide pin and the guide groove is changed, so that additional force is required to rotate the partition body. Moreover, since the positional relationship between the guide pin and the guide groove is also staggered when the door piece is closed, the guide pin is caught on the inclined surface of the guide groove, and the problem that the partition body cannot be completely rotated to maintain the half-open state ( The door is half open and the air leaks.) Therefore, consider The width of the guide groove is widened (that is, the guide pin can be inserted into the maximum entrance width of the guide groove when the guide pin and the guide groove are inserted). However, the widening of the entrance of the guide groove is effective for the countermeasure against the blanking, but the rotation of the partition body due to the shifting of the guide pin position is poor, the opening and closing operation of the flap is heavy, or the flap is half-opened. Bad conditions, but not a fundamental solution.

The present invention proposes a door piece structure having a movable guide pin different from Patent Documents 1 to 3. The object of the present invention is to provide a refrigerator having a door piece structure, even if the refrigerator body is deformed or the door piece is moved downward, When the position of the guide groove of the guide pin and the spacer body is shifted in the initial disassembly or the like, the deterioration of the door opening and closing force, the rotation failure of the partition body, the heavy opening and closing operation of the door piece, or the half opening of the door piece can be solved. situation.

The refrigerator of the present invention includes: a box-shaped body; two door pieces that are rotatably attached to the opening of the body such that the opening is opened and closed in a left-right direction; a guide pin is disposed on the An upper inner side of the opening of the main body; the partition body is rotatably provided on the back surface of the opposite end portion of the freely rotatable mounting portion of one of the door pieces, and extends in the up-and-down direction; The groove is disposed at an upper portion of the partition body, and the guide pin is inserted or removed corresponding to an opening and closing operation of the one of the door pieces; wherein the guide pin has a moving mechanism that moves in a horizontal direction.

According to the refrigerator of the present invention, in the refrigerator having the left and right split door panels, the guide pin has a moving mechanism that moves in the horizontal direction, thereby making the contact area of the guide pin and the guide groove small, that is, moving to and guiding the groove Smaller clamping force In addition, it is possible to solve the problem that the opening and closing force of the shutter is deteriorated due to the positional change of the spacer body and the guide pin, the rotation of the spacer body is poor, the opening and closing operation of the shutter is heavy, or the door is half opened.

In addition, in the first drawing, the following drawings are diagrams showing the mode, and the relationship between the dimensions of the respective constituent elements may be different from the actual situation.

Embodiment 1

1 is a schematic perspective view showing a state in which one door piece 1 of the refrigerator 100 according to Embodiment 1 of the present invention is opened, and also includes an enlarged view of the guide pin attaching portion (a) and an enlarged view of the upper portion of the partition body (b). . Figure 2 is a first embodiment of the present invention. A schematic perspective view of a state in which one of the door pieces 1 of the refrigerator 100 is closed.

The refrigerator 100 according to the first embodiment of the present invention has a door piece 1 that opens and closes left and right, and a door piece 2, and one of the door pieces 1 has an independent opening and closing structure that can be opened and closed regardless of opening and closing of the other door piece 2.

The left and right split door panels 1 and 2 are attached to the opening and closing of the front opening of the refrigerator compartment of the refrigerator 100, and the one end side of each of the door panel 1 and the door panel 2 is rotatably attached to the box shape. The opening 4 of the body 3. Further, a magnetic spacer (not shown) is attached to the periphery of the back surface of each of the door piece 1 and the door piece 2 to cover the open end of the body 3, and the magnetic spacer is prevented when the door piece 1 and the door piece 2 are closed. Cold air leaks.

Here, the structure of the left and right split door panels will be described.

As shown in FIGS. 1 and 2, the partition body 5 is rotatably provided on the back surface of the end portion on the opposite side of the freely rotatable mounting portion of the one door piece 1, and extends in the vertical direction. A guide groove 7 having a curved shape is formed on the upper portion of the partition body 5, and the guide pin 6 provided on the inner side of the upper side of the opening portion 4 of the main body 3 is inserted into and removed from the guide groove 7.

The partition body 5 is rotated at an angle of, for example, 90 degrees, and in the open state of the door piece, as shown in Fig. 1, the back surface of the door piece 1 is perpendicular to the angle. When the door piece 1 is closed from this state, the guide pin 6 provided on the inner side of the upper side of the opening 4 of the main body 3 is obliquely inserted into the guide groove 7 provided in the upper curved shape of the partition body 5. When the guide pin 6 enters the guide groove 7, the partition body 5 is rotated outwardly around the rotation center 5a, and when the door piece is closed, the partition body 5 and the back surface of the door piece 1 are parallel (as shown in Fig. 2). . The exposed portion (the gasket adhesion portion 5b) of the separator body 5 and the magnetic gasket (not shown) attached to the back surface of the other door panel 2 are in close contact with each other. Since the magnetic spacer has magnetic properties, the magnetic spacer is placed on the spacer body 5 in the closed state of the door piece. The sheet-fitting portion 5b and the opening end portion of the body 3 are passed through a magnetic spacer to closely contact the door sheet 1 and the door sheet 2. Therefore, it is possible to independently open and close one of the door pieces 1 regardless of the opening and closing operation of the other door piece 2, and the cold air in the main body 3 does not leak out when the door is closed.

Fig. 3 is a plan view showing the positional relationship between the guide pin 6 and the guide groove 7 when the door piece of the first embodiment of the present invention is closed. In addition, Fig. 4 is a view showing a moving mechanism of the guide pin 6 according to the first embodiment of the present invention, wherein (a) is an exploded view of the mounting portion of the guide pin 6, and (b) is an assembled view of the mounting portion of the guide pin 6. (c) is the AA cross-sectional view of (b).

As shown in Fig. 3, when the door piece is locked, the guide pin 6 is obliquely inserted into the distal end portion (the deepest portion) of the guide groove 7, and as long as the door piece 2 is not opened, the door piece 1 and the door piece 2 are for sealing the body 3 status.

In the first embodiment, the guide pin 6 has a mechanism that can move in the horizontal direction as indicated by the dotted arrow in the third and fourth figures. The moving mechanism of the guide pin 6 is such that, as shown in Fig. 4, springs 8a and 8b are provided on both sides of the guide pin 6.

It is explained with reference to Fig. 4. The guide pin 6 and the guide 9 are formed integrally, and are formed in an elongated shape. The guide pin 6 formed by the protrusion protrudes through the opening portion 11 provided in the guide pin holding member 10, and the guide member 9 of the guide pin 6 is slidably disposed on the guide pin holding member 10 so that the opening is opened The portion 11 moves in the horizontal direction (the direction of the dotted arrow). Further, springs 8a and 8b are provided between the guide 9 and the end portions of the guide pin holding member 10. The guide pin holding member 10 is disposed on the inner side of the upper side of the opening portion 4 of the body 3. Therefore, when the door piece 1 is opened and closed, the springs 8a and 8b apply an elastic force to the guide pin 6 from both sides, whereby the guide pin 6 moves to a position where the contact area with the guide groove 7 becomes small. Thereby, the separator body 5 and the guide pin 6 can be absorbed. Positional changes caused by machining errors, mounting errors, etc. That is, when the door piece 1 is closed, the spring 8b on the right side or the deep side antagonizes the resistance from the guide pin 6 to the guide groove 7 and pushes the guide pin 6 back, when the door piece 1 is opened, the left side or The proximal spring 8a antagonizes the resistance of the guide pin 6 to the guide groove 7 and pushes the guide pin 6 back, whereby the positional variation due to the above error can be absorbed.

As described above, according to the first embodiment, the springs 8a and 8b apply the elastic force to the guide pins 6 from both sides. Therefore, when the door piece 1 is opened and closed, the resistance of the guide pin 6 to the guide groove 7 can be reduced, and the guide pin 6 can be reduced. The guide pin 6 is moved to a position where it is difficult to apply a force to the groove shape of the guide groove 7. Therefore, the opening force and the blocking force of the door piece 1 can be reduced. Further, when the external force to the guide pin 6 is released, the guide pin 6 is automatically returned to the original position by the force of the springs 8a, 8b. Here, the "position that is difficult to apply force" is such that when the door piece 1 is opened and closed, the guide pin 6 moves to a position where the contact area with the guide groove 7 becomes small. The guide pin 6 is automatically moved to a "difficult position" by the springs 8a, 8b. Furthermore, the amount of movement of the guide pin 6 in the left and right directions is at most 15 mm. Further, the spring constants of the springs 8a, 8b are 5 N/mm.

In the first embodiment, the rotational force of the spacer body 5 is assisted by the force of the springs 8a and 8b, and the opening and closing force of the door piece 1 is reduced. Further, although the springs 8a, 8b are shown as compression springs, they may be tension springs.

In addition, since it is a fixed type of guide pin in the former model, the positional relationship of the guide pin and the guide groove of the spacer body is shifted, and the positional relationship of the diaphragm body is stopped in the middle of the rotation of the spacer body. In the first step, the guide pin 6 is moved to a position where the force is hard to be applied by the force of the springs 8a and 8b, so that the spacer body 5 is not locked, and a reliable turning operation can be realized. Therefore, it is possible to prevent the half-open mode of the door piece 1, and it is also possible to avoid problems such as cold air leakage or door alarm.

Instead of using the springs 8a and 8b described above, a magnet (not shown) may be used as the other moving mechanism of the guide pin 6, and the same effect can be obtained. That is, the guide pin 6 may be configured to move by the magnetic force (mutually repulsive force or attractive force) of the magnets on both sides.

Embodiment 2

Fig. 5 is a view showing the shape of the guide groove 7 according to the second embodiment of the present invention before and after the surface wide portion is enlarged.

In the second embodiment, the surface wide portion of the guide groove 7 is enlarged from (a) of Fig. 5 to the shape of (b). The guide pin 6 is movable as in the first embodiment.

As shown in FIG. 5( a ), the general guide groove 7 has a groove shape including an inner curved portion 7 a connected to the distal end portion 7 c (a curved portion located inside when the flap is closed) and an outer curved portion 7 b ( The curved portion located outside when the door piece is locked). Further, in the second embodiment, as shown in Fig. 5(b), the entrance portion of the outer curved portion 7b of the guide groove 7 is enlarged, so that the surface wide distance d2 of the guide groove 7 is larger than that in Fig. 5 ( a) The width of the guide groove 7 shown is a distance d1. Here, the surface width distance d1 is a distance from the pad attaching portion 5b of the spacer body 5 to the convex top portion 7e of the outer curved portion 7b, and the face width distance d2 is such that the top portion 7e is at the same position. The distance from the gasket adhesion portion 5b of the separator body 5 to the enlarged inlet end of the outer curved portion 7b. Further, the convex top portion 7e of the outer curved portion 7b is a portion of the outer curved portion 7b that faces the convex top portion of the inner curved portion 7a. The distance between the outer curved portion 7b and the shim close portion 5b is larger as it approaches the inlet end side of the guide groove 7. Thereby, the groove width of the guide groove 7 is larger as it approaches the inlet end side.

In the case where the guide pin 6 is of a fixed type, in the groove shape of the guide groove 7 as shown in (a) of FIG. 5, since the surface width of the guide groove 7 is narrow, the door piece is opened and closed. The deterioration of the force is severed by the positional changes of the partition body 5 and the guide pin 6. However, as shown in FIG. 5(b) of the second embodiment, in the groove shape in which the surface width of the guide groove 7 is enlarged, the guide pin 6 is easily inserted, and the error absorption effect of the movable guide pin 6 is matched. Further, since the error caused by the large positional displacement of the spacer body 5 and the guide pin 6 can be absorbed, the reliability of the opening and closing operation of the door piece 1 can be further improved.

Embodiment 3

Fig. 6 is a view showing a moving mechanism of the distal end portion of the guide groove 7 of the separator body 5 according to the third embodiment of the present invention. (a) and (b) of Fig. 6 are plan views showing a state in which the guide pin 6 and the spacer body 5 are joined, and (c) and (d) of Fig. 6 are plan views showing the internal configuration.

As shown in Fig. 6, in the third embodiment, the second end portion 7d having the same shape is provided in the distal end portion 7c of the guide groove 7 of the spacer body 5, and the second end portion 7d can be pushed by the guide pin 6. . The second end portion 7d is biased by the spring 12 in a direction relative to the guide pin 6. That is, in the third embodiment, the second end portion 7d and the guide pin 6 provided in the guide groove 7 are configured to be movable. Further, the spring 8a on the left side shown in Fig. 4 may be omitted, and only the spring 8b on the right side may be provided.

In the third embodiment, at the time of the closing operation of the door piece 1, the guide pin 6 is pushed back by the force of the right spring 8b until the guide pin 6 comes into contact with the second end portion 7d. Then, the guide pin 6 comes into contact with the second end portion 7d, and pushes the second end portion 7d until it reaches the position of the end portion 7c, and the force of the spring 12 and the spring 8b is balanced, so that the guide pin 6 is moved to a hard force. position.

When the door pin 1 is opened, when the guide pin 6 is released by the force of the spring 12 and the spring 8b, the guide pin 6 is smoothly pulled out from the guide groove 7, so that the operation of opening the door piece 1 can be smoothly performed.

According to the third embodiment, since the second end portion 7d provided in the distal end portion 7c of the guide groove 7 and the guide pin 6 are configured to be movable, the error-absorbing action of the movable guide pin 6 can be matched to move the guide pin 6 It is a position where it is difficult to apply force to the groove shape of the guide groove 7. Therefore, it is possible to prevent deterioration of the opening and closing force of the door piece 1, and it is possible to prevent the shutter body 5 from being locked without being locked, and it is possible to avoid problems such as half opening of the door piece 1, leakage of cold air, or alarm of the door piece.
