Filler assembly of side door refrigerator door {Filler assembly of side by side refrigerator's door}

The present invention relates to a filler assembly of a double-door refrigerator door, and more particularly, to a filler assembly of a double-door refrigerator door in which a filler can be forcibly easily folded and a folded state is maintained when a filler for preventing cold air leakage is unfolded.

Generally, a refrigerator is a household appliance that can store food and the like at a low temperature in a storage room inside the main body.

In recent years, a relatively frequently used refrigerating chamber is arranged on the upper part of the refrigerator, and a freezer is provided on the lower part, and the upper refrigerating compartment is opened and closed by a pair of rotary casement doors, and the freezer is a French-type refrigerator consisting of a drawer-type storage compartment that slides back and forth. Is commercially available.

The French door-type refrigerator prevents unnecessary space from being occupied due to the door in which the refrigerating chamber is opened, and the inside thereof is formed to be integrated, thereby enabling the use of an extended refrigerating chamber.

Since the French refrigerator does not have an intermediate partition in the upper refrigerating chamber, it is made of a single refrigerating chamber, and reliable sealing between the left and right doors is essential to prevent cold air from leaking.

In addition, vertical partitions or horizontal partitions for partitioning the refrigerating chamber are provided inside the main body, but the vertical partitioning may not be provided to widen the left and right widths of the refrigerating chamber as much as possible.

When the vertical bulkhead is not provided, a gap is formed between the doors on both sides, so that a filler is installed on any one of the doors installed on the left and right sides of the main body for sealing. That is, when each of the doors closes the storage compartment, the filler part prevents cold air in the refrigerator compartment from flowing out between the doors.

In the rotating groove portion 125, a departure preventing piece 126 is formed around the support shaft 124 to prevent the support shaft 124 from coming off.

The support shaft 124 is inserted from the bottom of the rotary groove 125 to the top to be coupled.

Then, the rotating groove portion 125 includes a closing cap detachable from the filler 110 so that the hinge bracket 122 is detachable.

The guide guide portion 140 is to rotate the filler 110 to the sealing position when the door 10 is closed. The sealing position refers to a state unfolded side by side with the door 10 to seal the gap between the doors 10 facing each other.

As shown in FIG. 8, the guide guide 140 contacts the protrusion 142 provided at the top of the filler 110 and the protrusion 142 when the door 10 is closed, so that the filler 110 is in a sealing position. It includes a guide block 144 to guide the protrusion 142 to be rotated.

The guide block 144 is provided on the upper surface of the front end of the storage chamber, and a guide groove 145 for guiding the protrusion 142 is formed. That is, in the open state of the door 10, the filler 110 is in a fixed position, and when the door 10 is closed, the protrusion 142 is inserted into the guide groove 145 of the guide block 144 and guided. , It is rotated to the sealing position.

The restraint part is selectively constrained to rotate the filler 110 in connection with the guide guide part 140, and when the door 10 is opened, the rotation of the filler 110 is restrained so that the filler 110 is in position. And, when the door 10 is closed, the rotational restraint of the filler 110 is released and can be rotated to the sealing position by the protrusion 142 and the guide block 144.

The restraint portion is provided with a cutting groove provided at the lower end of the protruding portion 142 and a restraining protrusion 154 and a protruding portion 142 provided on the hinge portion 120 to selectively match the cutting groove according to the elevation of the protruding portion 142. It consists of a coil spring (156) to restore the original position. That is, the protrusion 142 is made of a separate material from the filler 110, the upper end protrudes to the upper portion of the filler 110, the lower end is formed to extend downward, and an incision groove is formed in the lower end.

The rotation groove portion 125 is provided with a release preventing piece 126 that prevents the separation of the support shaft 124.

The departure preventing piece 126 includes a rotation limiting hole 127 surrounding the periphery of the support shaft 124 and limiting the rotation range of the restraining protrusion 154. That is, the restraining protrusion 154 of the support shaft 124 is in a state accommodated in the rotation limiting hole 127 of the departure preventing piece 126. Due to this, when the unfolding of the filler 110 is in contact with the inner surface of one side of the rotation limiting hole 127, the rotation angle is limited.

The protruding portion 142 is guided by the slide rail portion when ascending and descending from the pillar 110.

The slide rail part is made of a separate part from the filler 110 and is fixed inside the filler 110.

The slide rail portion is provided with an accommodating groove portion accommodating the constraining protrusion 154 chamfer 154 when the constriction protrusion 154 and the incision groove coincide.

The receiving groove portion is formed by the lower portion of the slide rail portion is recessed, the fixed position of the filler 110, that is, when the folding of the filler 110, the locking projection 154 is accommodated in the receiving groove portion, thereby the filler ( By blocking the shandong of 110), it is possible to prevent the filler 110 from deviating.

Hereinafter, the operation and effects of the sealing device of the French refrigerator having the above structure will be described.

First, looking at the assembly of the sealing device 100, a protrusion 142 is installed inside the filler 110, which is divided into the front plate and the rear case.

The protruding portion 142 is an upper end protruding to the upper portion of the filler 110, coupled to the slide rail portion inside the filler 110, is elastically supported by the coil spring 156.

Then, the fixing part 123 of the hinge bracket 122 is mounted to the door 10 by a separate fastening member 129, and the support shaft 124 is accommodated in the rotating groove part 125 of the filler 110.

At this time, the restraining protrusion 154 formed on the support shaft 124 is inserted into the rotation limiting hole 127 to limit the rotation range of the pillar 110 centered on the support shaft 124.

In addition, the lower space of the rotating groove 125 is covered with the finishing cap which is hook-coupled to the remaining space of the rotating groove 125 after the support shaft 124 is engaged.

Then, the operation of the filler 110 by opening and closing the door 10 will be described.

The first filler 110 is located in the sealing position. That is, it is in close contact with the main body in a state unfolded on the rear surface between the doors 10 on both sides facing each other to seal the inside of the main body, thereby preventing the outflow of cold air.

When the door 10 is opened, the door 10 is rotated and opened around the door hinge.

Then, the protrusion 142 is guided along the guide groove 145 of the guide block 144, and the filler 110 is folded in the vertical state of the door 10 according to the guide groove 145 guide. do.

At this time, the restraining protrusion 154 of the support shaft 124 is in a state accommodated in the receiving groove by rotation of the filler 110. That is, the pillar 110 is rotated and folded about the axis 124 of the hinge bracket 122, and the protrusion 142 deviated from the guide block 144 is raised by the elastic force of the coil spring 156. , As the protrusion 142 rises, the incision groove is deviated from the restraining protrusion 154 of the hinge portion 120.

As described above, the filler 110 can be closed without colliding or interfering with the other door 10 or the guide block 144 when the one door 10 is closed in the folded state.

At this time, when the protrusion 142 is inserted into the guide groove 145 of the guide block 144, the protrusion 142 comes into contact with the guide block 144 and is pressed down.

Thereafter, the incision groove is coincident with the restraining protrusion 154 by the descending of the protruding portion 142 so that the filler 110 is rotatable about the hinge portion 120.

And, as shown in Figure 8, the protrusion 142 is guided along the guide groove 145 of the guide block 144 to rotate the filler 110 to the sealing position.

When the filler 110 is rotated and unfolded to the sealing position, the front plate of the filler 110 is in close contact with the gasket of each door 10, and it is possible to prevent the cold air in the storage compartment from flowing out between the gaps between the two doors 10. have.

In the conventional refrigerator as described above, when the door 10 is closed, the filler 110 is unfolded to prevent cold air leakage, and when the door 10 is opened, the filler 110 is folded to prevent collision with other parts. .

However, in the case where there is a lot of storage in the door 10 or the door 10 is opened with a strong force or a short time, the protrusion 142 is not sufficiently lowered by the tension of the coil spring 156 and thus the filler 110 ), the door 10 is opened in a state where it is not completely folded, and a malfunction in which the filler 110 is unfolded has occurred.

If such a malfunction occurs, since the protrusion 142 is in an elevated state, when the filler 110 is rotated, the protrusion 142 is caught by the restraining protrusion 154 and cannot fold the filler 110, and the guide protrusion 142 Press to descend and the filler 110 can be folded only in a pressed state. However, in the case of a user who has not been trained on how to operate the filler 110, it is difficult to fold the unfolded filler 110, resulting in a number of user claims.

In addition, when the user closes the door 10 in a state in which the filler 110 is unfolded, the filler 110 collides with the other door 10 or collides with the guide block 144 to damage the exterior or the filler 11 to be damaged. There was a danger.

Hereinafter, a preferred embodiment of the present invention will be described based on FIGS. 1 to 8.

Filler 110 provided on one side door 10 of a French-type refrigerator having a single refrigerator compartment and a top door according to the present invention, and a hinge part connected to the door 10 so as to fold or unfold the filler 110 , Filler rotation allowable portion (140a) coupled to the filler 110 to selectively allow rotation of the filler (110), formed in the hinge portion when the filler rotation allowable portion (140a) is folded to rotate It includes an allowable guide 128 to guide the movement.

In more detail, the present invention, the filler rotation allowable portion (140a) is a protrusion 142 that protrudes so as to be elevated on the upper end of the filler 110, and the allowable portion body 146 connected to the lower side of the protrusion 142 And, including a cut groove 152 formed on one side of the permissible portion body 146, and a blocking wall 149 disposed under the cut groove 152, wherein the hinge portion includes a support shaft 124 and the support shaft. It includes a projection 154 formed on one side of the outer circumferential surface of 124, and a chamfer 128 formed on the projection 154, wherein the chamfer 128 is the allowable additional guide 128, the blocking wall ( As the 149) rides over the chamfer 128, the filler rotation allowable portion 140a descends and the filler 110 is folded.

Due to this, when the filler rotation allowable portion 140a descends on the chamfer 128, the filler 110 may be folded because the protrusion 154 passes through the incision groove 152 and is accommodated in the protrusion receiving portion 162. That is, when the filler 110 is unfolded due to a malfunction when the door 10 is opened, when the filler 110 is folded, the filler rotation allowable part 140a descends by the allowable additional guide 128 to force the filler 110. It is easy to use because it can be easily folded.

A blocking wall chamfer 148 that is in contact with the chamfer 128 when the filler 110 is folded is further formed at an edge of the blocking wall 129 on the side of the cutting groove 152. Therefore, in the present invention, when the filler 110 is folded, since the blocking wall chamfer 148 of the filler rotation allowable portion 140a and the chamfer 128 of the protrusion 154 contact each other, the filler rotation allowable portion 140a descends more easily. The user can easily fold the unfolded filler 110.

The configuration of the filler 110 assembly of this embodiment is the same as the configuration except for the protrusion 154 of the hinge portion and the filler rotation allowable portion 140a among the technologies published in Patent Document 3, and is largely illustrated in FIGS. 1 to 2B. As described above, the rear case 112 and the front plate 114 are combined to form a space in which a filler rotation allowable part 140a is accommodated therein, and a fixing part 123 mounted on the door 10 The hinge bracket 122 including the support shaft 124 connected to the fixing part 123, the hinge groove 122 provided in the filler 110 so that the hinge bracket 122 is rotatably accommodated, 125 of the projection 154 A filler rotation allowable part 140a to rotate the filler 110 to the sealing position when the rotation limiting hole 127, the closing cap 130, and the door 10 are provided in the filler 110 to limit the rotation range. Guide guide 140 including guide groove 145 of guide block 144, restraint 150 including filler groove 152 and protrusion 154 and coil spring 156, filler 110 ) It is accommodated inside and includes a slide rail portion 160 having a protrusion receiving portion 162 in communication with the incision groove 152.

The coil spring 156 supports the pillar rotation allowable portion 140a to move up and down.

For other configurations or descriptions of the above configurations, refer to the above-mentioned'Technical Background of Invention', Patent Documents 3, 7 and 8.

As described above, the present invention differs from the projection 154 of the hinge portion and the filler rotation allowable portion 140a as shown in FIG. 3 as compared to the prior art Patent Document 3.

The allowable part body 146 of the filler rotation allowable part 140a of the present invention is slidably coupled to the slide rail part 160, and the slide rail part 160 coupled with the allowable part body 146 is a filler 110 ).

The protrusion 142 is guided along the guide groove 145 of the guide block 144 as the protrusion 142 is shown in FIG. 8 to rotate the filler 110 when the door 10 is opened or closed.

As shown in FIG. 3, the permissible portion body 146 includes an upper body 146a having a spring fitting portion 156a formed on the front surface, a lower body 146b having a cut groove 152 and a blocking wall 149 formed thereon. Is made of

The left and right widths of the upper body 146a are wider than the left and right widths of the lower body 146b, and the front and rear widths of the upper body 146a are thicker than the front and rear widths of the lower body 146b.

In the center of the upper body 146a, an accommodating groove (not shown) in which the rear half of the coil spring 156 is accommodated is formed long in the vertical direction. A rail-side spring fitting portion (not shown in the figure), which is formed on the slide rail portion 160 and fitted with the lower side of the coil spring 156, is accommodated in the accommodation groove.

The upper side of the coil spring 156 is fitted into the spring fitting portion 156a.

The incision groove 152 is formed by cutting one side of the allowable portion body 146, that is, the right side of the lower body 146b.

The surface forming the incision groove 152 consists of an upper surface, a lower surface, and a side surface connected to the upper surface and the lower surface.

The blocking wall 149 is connected to the lower end of the lower body 146b, and is substantially rectangular parallelepiped.

Since the lower body 146b has an incision groove 152, the blocking wall 149 appears to protrude from the lower body 146b to one side.

The protrusion 154 is formed to protrude from the rear side of the outer circumferential surface of the support shaft 124.

The protrusion 154 has a right side 154a facing the fixing portion 123, an upper surface, an allowable contact surface connected to the right surface 154a, and an upper surface, the right surface 154a, the upper surface, and a lower end of the allowable contact surface It is made by including the lower surface connected to.

The chamfer 128 is formed on the allowable portion contact surface of the projection 154.

More specifically, the chamfer 128 is formed such that the cross-sectional area of the horizontal cross-section of the projection 154 becomes smaller as it goes from the upper side to the lower side. In addition, the chamfer 128 is a substantially triangular surface that increases in width from the upper side to the lower side. In other words, the chamfer 128 is formed to be inclined to become closer to the support shaft 124 as it goes from the upper side to the lower side.

Meanwhile, the blocking wall chamfer 148 is formed over the lower surface and the blocking wall 149 forming the incision groove 152.

In more detail, the blocking wall chamfer 148 is formed to increase the cross-sectional area of the horizontal cross-section of the lower body 146b from the upper side to the lower side, as opposed to the chamfer 128. In addition, the blocking wall chamfer 148 is an approximately triangular surface whose width narrows from the upper side to the lower side.

In this way, the chamfer 128 and the blocking wall chamfer 148 are formed in a shape corresponding to each other. Therefore, when the barrier wall chamfer 148 is in contact with the chamfer 128 during the process of folding the filler 110, the chamfer 128 and the barrier wall chamfer 148 may be arranged side by side, thereby allowing the filler rotation part ( 140a) can easily descend on the chamfer 128. In addition, since the filler rotation allowable portions 140a and the protrusions 154 are in contact with the chamfers 128 and 148 having shapes corresponding to each other, the filler rotation allowable portions 140a or the protrusions 154 are not damaged. The movement of the filler rotation allowable portion 140a through the contact of the chamfer 128 and the blocking wall chamfer 148 is similar to the movement using the cam, and the projection 154 on which the chamfer 128 is formed acts like a straight cam. Do it.

The area of the chamfer 128 is larger than the area of the blocking wall chamfer 148. Therefore, even if the filler rotation allowable portion 140a is slightly lower than the normal position or slightly raised, the chamfer 128 and the blocking wall chamfer 148 may contact each other when the filler 110 rotates, so that the filler 110 can be folded. Can.

On the other hand, the filler 110 assembly having the above configuration is a state in which the filler rotation allowable portion 140a is raised when the coil spring 156 is not compressed. That is, the state in which the filler rotation allowable portion 140a is lowered is when the coil spring 156 is compressed.

The filler 110 can be folded only when the filler rotation allowable portion 140a is lowered.

When the filler 110 is unfolded, the filler rotation allowable portion 140a is in an elevated state, so as shown in FIGS. 4A and 4B, the incision groove 152 is partially exposed to the outside. Therefore, in this state, even if the filler 110 is rotated in the folding direction, the protrusion 154 cannot be passed through the incision groove 152 by being caught in the filler rotation allowable part 140a. Therefore, only when the filler rotation allowable portion 140a is lowered, the incision groove 152 is exposed to the outside, so that the protrusion 154 can pass through the incision groove 152, and thus the filler 110 can be folded.

Hereinafter, an example of a process in which the filler 110 is folded while the door 10 is opened will be described.

First, as shown in FIGS. 4A and 4B, the chamfer 128 and the blocking wall chamfer 148 are disposed on the left or right side of each other.

At this time, when the unfolded filler 110 is rotated toward the folding direction, that is, the door 10 side, the blocking wall chamfer 148 of the filler rotation allowable part 140a rotated together with the filler 110 is illustrated in FIGS. 5A and 5B. As at a certain point of rotation, it contacts the chamfer 128 of the projection 154.

Subsequently, when the filler 110 is further rotated, the coil spring 156 is compressed while the filler rotation allowable portion 140a is pressed against the protrusion 154, and the filler rotation allowable portion 140a gradually descends. At this time, the hinge portion is fixed to the door 10 so that the position is maintained.

Then, when the filler 110 is further rotated to completely fold as shown in FIG. 6, the right side of the projection 154 is passed through the chamfer 128 by the filler rotation allowable portion 140a descending on the chamfer 128. If it is located behind the 154a), the filler rotation allowable portion 140a is lifted again as when the filler 110 is unfolded because the pressing by the protrusion 154 is removed.

Thus, when the filler 110 is completely folded, the filler rotation allowable portion 140a is disposed between the protrusion 154 and the fixing portion 123 of the hinge portion. Therefore, the filler rotation allowable portion 140a is fixed to the right side 154a of the protrusion 154 so that the filler 110 cannot be rotated so that the filler 110 is not expanded again.

On the other hand, as shown in the drawing but not described above, the present invention is a central hinge 171 connected to the center of the filler 110 and the center of the door 10, and a lower side connected to the lower side of the filler 110 and the lower side of the door 10. The hinge 173 is further included.

On the other hand, the elastic portion 156, the coil spring 156 is applied in this embodiment, the sponge may be applied.

As described above, the present invention has been described with reference to preferred embodiments, but those skilled in the art may vary the present invention without departing from the spirit and scope of the invention as set forth in the claims below. It can be carried out by changing or modifying it.
