[Document 1] Japanese Unexamined Patent Publication No. Hei-292981

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and in particular, a refrigerator including a refrigerator door in which foam insulation is filled in a space formed by a frame, a door outer plate and a door inner plate to solidify the frame, the door outer plate and the door inner plate. Would be suitable.

As a conventional refrigerator, there exist some which are disclosed by Unexamined-Japanese-Patent No. 10-292981 (patent document 1), for example.

The refrigerator includes a refrigerator main body that forms a storage compartment, and a refrigerator door in which foam insulation is filled in a space formed by a frame, a door outer plate, and a door inner plate to solidify them.

The refrigerator door is made in a square shape such that the corner portion of the housing is not visible from the front. In a typical refrigerator, a refrigerator door is made larger than a refrigerator main body.

In addition, the handle of the refrigerator is attached by using the adhesive force of the foam insulation without using screws or the like. In other words, the refrigerator is formed by bending the left and right ends of the door outer plate forming the door and installing end pieces integrally formed with handles on the upper and lower sides, and foam insulation and so-called urethane foam in the box-shaped container made by the door outer plate and the end piece. It is filled with the adhesive force of the urethane foam and the end piece is fixedly attached to the door outer plate integrally.

This handle is reliable as a fixed attachment structure of the handle due to the large adhesion area between the end piece and the urethane foam, the handle being integral with the end piece, and the like. That is, since the force applied to the handle portion of the handle is received by the entire end piece, there is no problem that the end piece is moved by the operating force of the handle when using the handle.

In the conventional refrigerator, it is considered to attach a rounding part to the corner of the refrigerator door in consideration of the design. However, if the rounding part is to be attached in this way, the refrigerator door may have the upper surface 34 of the refrigerator door 31 so that the corner portions P1 and P2 of the refrigerator main body 33 are not seen from the front as shown in FIG. It is made higher than the ceiling surface 35 of the refrigerator body 33.

Making the door 31 larger than the refrigerator main body 33 means that the outer dimension, which is the target at the time of calculating the CER (internal efficiency: inner / outer dimensions), is not the refrigerator main body 33 in which the object is stored. Since 31 is an object, it was not preferable to provide the rounding part 32 in the refrigerator door 31 from the surface on the CER.

As a result, sticking of the rounded portion to the corner portion of the refrigerator door 31 has been inhibited, which has been a design limitation.

In the conventional refrigerator, since the handle is formed integrally with the end piece, there is a problem that the handle is restricted to the color tone or shape with the end piece. Thus, as a handle attachment structure that eliminates this restriction, it is considered to attach a handle independent from the end piece.

As the attachment structure of the handle which has released this restriction, what is shown in FIGS. 10-12 is considered.

First, the attachment structure of the handle of FIG. 10 will be described. The door body 36 is composed of a door outer plate 37, an end piece 38, a door inner plate 39, and a urethane foam 40 that is a foam insulation. The urethane foam 40 fixes the door outer plate 37, the end piece 38, and the door inner plate 39 integrally.

The handle 41 is attached to the opposite pivot side of the door body 36. The handle 41 has an attachment portion 42 for holding the door outer plate 37, a fixing portion 43 for securing the adhesive force of the urethane foam 40 to fix the handle 41, and a handle. It is comprised by the part 44.

The fixed attachment of the handle 41 is that the door outer plate attachment portion 42 is mechanically connected to the door outer plate 37 and that the fixing portion 43 is adhesively embedded in the urethane foam 40. It is done. The sealing material 38a provided on the end piece 38 side seals the gap generated between the handle 41 and the end piece 38 to prevent leakage of the foamed heat insulating material 40.

When the door main body 36 is opened and closed with the handle 44 of the handle 41, the force applied to the handle 41 is applied to the door outer plate attaching portion 42 and the fixing portion 43. For this reason, the adhesive force with the urethane foam 40 is very important.

However, in the case of the attachment structure of the handle 41 shown in Fig. 10, since the gap 45 made by the fixing portion 43 and the packing attachment groove 39a provided on the door inner plate 39 side is narrow, the urethane foam It becomes the obstacle of the flow to the clearance 46 side of 40, and the urethane foam 40 is not filled well in the clearance 46 made by the fixing part 43 and the end piece 38, and the fixing part ( There is a fear that sufficient adhesive force may not be obtained. That is, if the fixing part 43 does not adhere enough to the urethane foam 40, when the door body 36 is opened and closed with the handle part 44, there exists a possibility that the function of the handle 41 may be impaired. have. This is a problem that is more likely to occur as the fixing part 43 which tries to enlarge the adhesive area with the urethane foam 40 is enlarged.

Next, the attachment structure of the handle of Fig. 11 will be described. The handle 41 shown in FIG. 11 separates the base portion 47 and the handle portion 48 and fixes the base portion 47 to the door outer plate 37 and the end piece 38. That is, one end of the base portion 47 is fixed by sandwiching the door outer plate 37, and the other end is fixedly attached to the end piece 38 by a screw 48. The handle portion 44 is fixedly attached by engaging the hook 49 and the locking portion 50 provided on the base portion 47 with the base portion 47.

With the attachment structure of the handle 41 having such a configuration, the makeup part 38a of the end piece 38 covering the outer periphery of the door outer plate is divided by the handle 41, which is undesirable for design purposes, and the handle ( There was a problem that 41) became two parts of the base portion 47 and the handle portion 44. Moreover, since the screw 48 is needed or the hook 49 for fitting to the base part 47 is needed, there existed a problem that a shaping | molding die became complicated.

Next, the attachment structure of the handle of FIG. 12 will be described. The handle 41 shown in Fig. 12 is a part of which the handle 41 of Fig. 11 is a part of the article. The fixing of the base 50 is performed by engagement with the door outer plate 37 and the end piece 38. It is performed by fixing the screw 51 to the part.

In the case of the attachment structure of the handle 41 having such a configuration, as in Fig. 11, the makeup part 38a of the end piece 38 is divided by the handle 41, and the screw 51 is the door main body 36. Since it leaks to the side), there was a problem that it is not preferable in design.

An object of the present invention is to provide a refrigerator which can make the shape of the refrigerator door good in design while improving the CER (effective content: internal / external dimensions).

In addition, another object of the present invention is to provide a refrigerator capable of reliably attaching the handle by using the adhesive strength of the foam insulation, the side edge frame and the mechanical strength of the door outer plate.

In order to achieve the above object, the present invention is filled with a foam insulation in the space formed by the refrigerator main body and the frame, the door outer plate and the door inner plate to form a storage compartment integrally the frame, the door outer plate and the door inner plate. A refrigerator having a solidified refrigerator door, wherein the door outer plate is a door outer plate having a large rounding part at both corners of the upper end, and side edge frames constituting frames on both sides of the refrigerator door are formed of the door outer plate. A side edge frame having a rounding part covering the rounding part, and a projection part for hiding corners of the refrigerator main body is provided in the rounding part, and the upper frame constituting the frames on both sides of the refrigerator door has its upper surface on the ceiling surface of the refrigerator. It is in the configuration that I made roughly.

More preferred embodiment of this invention is as follows.

(1) The pin base which receives the hinge pin of the said refrigerator main body in the protrusion part provided in the rounding part of the said side edge frame.

In order to achieve the above another object, the present invention is filled with a foam insulation in the space formed by the refrigerator body and the frame, the door outer plate and the door inner plate to form a storage compartment to integrate the frame, the door outer plate and the door inner plate. A refrigerator having a refrigerator door solidified with a frame, wherein the door forms a handle separately from the frame, the handle includes a fixing part and a handle part, and the fixing part is located at a side of a side edge frame constituting the frame. It is set as the structure provided with the 1st fixing member which follows, and the 2nd fixing member which clamps the said door outer board.

EMBODIMENT OF THE INVENTION Hereinafter, one Embodiment of this invention is described with reference to drawings. 1 is a front view of the refrigerator according to the present invention, FIG. 2 is a sectional view A-A of the door of FIG. 1, FIG. 3 is a sectional view B-B of the door of FIG. 1, and FIG. 4 is a sectional view C-C of the door of FIG. 5 is an explanatory view of the configuration before the door assembly of FIG. 1, FIG. 6 is an enlarged explanatory view of the refrigerating compartment door of FIG. 1, FIG. 7 is an enlarged explanatory view of part D of FIG. 6, and FIG.

First, in Fig. 1, this refrigerator main body 1 is a three-door type refrigerator having a refrigerator compartment, a vegetable compartment and a freezer compartment in order from the top, and a refrigerator compartment door 2 and a vegetable compartment door (in the front openings of the refrigerator compartment, the vegetable compartment and the freezer compartment). 3) It has the freezer compartment door 4.

The outer circumferential three sides of the refrigerating compartment door 2 are surrounded by the makeup members 7 and 7 and the makeup member 8 formed by the side edge frames 5 and 5 and the upper frame 6. In addition, two sides of the vegetable compartment door 3 are surrounded by a makeup member of the side edge frames 9 and 9, and the freezer door 4 is formed at each of the side edge frames 10 and 10 and the lower frame 11, respectively. Three sides are surrounded by a makeup member (not shown). As a whole, the refrigerator door has a design in which the entire outer circumference is surrounded by a makeup member.

In addition, the refrigerator door has rounded corners 12 by rounding both corners of the upper end of the refrigerating compartment door 2 and both corners of the lower end of the freezing compartment door 4 to a large R.

As a result, the refrigerator is not very different from the commercial refrigerator design, and adjacent to the refrigerator compartment door 2 and the vegetable compartment door 3, and adjacent to the vegetable compartment door 3 and the freezer compartment door 4, respectively. As there is no frame, it provides stylish design.

That is, the side without a frame forms a flange by bending an iron plate, but the remaining side is formed in a flat plate, and the former frame forms a vertical rising flange.

Next, the relationship between the refrigerator compartment door 2 and the refrigerator main body 1 is demonstrated. The relationship between the refrigerator main body and the door which is generally commercially available is the width of the refrigerator main body 1 so that when the refrigerator main body 1 is viewed from the front of the door as described above, the refrigerator main body 1 becomes a shade of the door. In both height directions, the refrigerating compartment door 2 is made large. However, it is also well known that making the door larger than the refrigerator main body 1 becomes a direction that makes the effective CER (internal / outer dimension) worse. The upper surface 13 of the refrigerating chamber door 2 in the present invention is made approximately in line with the ceiling surface of the refrigerator main body 1, and the CER is improved.

When the upper surface 13 of the refrigerating compartment door 2 and the ceiling surface height of the refrigerator main body 1 are aligned, and the rounding part 12 is provided in the side edge frames 5 and 5 as mentioned above, the refrigerator main body 1 The corner part at the side of side is seen from the front of the door through the rounding part 12.

The present invention is characterized in that the corner portion of the refrigerator body 1 is not visible through the rounding part 12. This concrete means is explained in full detail below.

Therefore, the refrigerator door 2 of the present invention can be said to be an excellent refrigerator door in terms of design (rounding part 12) as well as in terms of CER.

Next, Figs. 2 to 4 will be described. In Fig. 2, reference numeral 5 denotes a side edge frame, 13 a door outer plate, 14 a door inner plate, 15 a urethane foam of foam insulation, and 16 a handle provided at an opposite pivot side end of the door 2. The handle 16 is an integral resin molded article composed of the fixing portion 17 and the handle portion 18. More specifically, the fixing portion 17 is outside the door of the first fixing member 17a along at least the back side and the side member 19 of the makeup member 7 and the back side 21 (foam insulation side) of the side edge frame. It consists of the 2nd fixed frame 17b which has the board 13 clamping part 20. As shown in FIG. Reference numeral 22 is a thin plate-shaped rib that enlarges the contact area with the foamed heat insulating material 15, and is provided in the longitudinal direction of the front fixing part 17 as shown in the purchase drawing. Of course, the rib 22 is provided on the urethane foam 15 side of the fixing portion 17. In other words, the rib 22 is provided in the opposing part of the handle part 18, and ensures the intensity | strength (adhesive strength) of the part with a handle | sticker.

Reference numeral 23 is a cross-section c-shaped core provided between the rib 22 and the back member 21. The core 23 has a side edge as shown between the front rib 22 and the rib 24 provided in the bent member portion of the first fixing member 17a (the distal end of the first fixing member 17a). Frame (5) is provided over the entire length. This is for ensuring the fixed attachment of the 1st fixing member 17a with the foam heat insulating material. That is, it plays a role of not only expanding the contact area but also pressing the movement of the fixing member 17a.

Reference numeral 25 is a groove for attaching a packing (not shown) provided in the door inner plate. The handle 16 of the refrigerator door 2 having such a configuration first assembles the core 23 using the first fixing member 17a of the handle 16 and then attaches the door outer plate to the clamping portion 20. Narrow it. Thereafter, after attaching the first fixing member 17a to the side edge frame 5 so as to surround the door inner plate 14, the door outer plate 13, the handle 16, and the side edge frame 5 are assembled. ), The urethane foam which is the foam heat insulating material 15 is filled in the space which the door inner board 14 makes, and it has the adhesive force of this urethane foam, and attaches and fixes each member integrally. At this time, the handle 16 is firmly fixed to the ribs 22 and 24, the core 23, and the first and second fixing members 17a and 17b by being in close contact with the urethane foam.

In this case, the handle 16 of the present application is characterized in that the core 23 is fixed to draw to the side edge frame 5 side. In other words, where the first fixing member 17a of the handle 16 is absent, the locking hook 26 is provided so that the core 23 is directly attached to the side edge frame 5 (see Fig. 3).

Next, with reference to Fig. 5 to Fig. 8, an example will be described in which the rounded portion 12 is provided in the side edge frame 10 of the refrigerating compartment door 2 to greatly change the design. As shown in Fig. 7, the refrigerating compartment door upper surface 2a is made equivalent to or slightly above the ceiling surface 1a of the refrigerator main body 1. This can significantly increase the CER (effective content). In the drawings, reference numeral 2 denotes a refrigerating chamber door, 6 an upper frame, 10 a side edge frame, 12 a rounding part of the side edge frame 10, and 13 a door outer plate. The door outer plate 13 has a rounded portion 12 at the upper part of the refrigerating compartment door 2 and a lower part of the freezer compartment door 4. The rounding part referred to here refers to a large arc having a radius of about 10 mm. The rounded portion 12 of the side edge frame 10 is made into a shape that matches the rounded portion of the door outer plate 13. Reference numeral 13a denotes a cutout portion for attaching the handle provided in the door outer plate 13, and the handle 16 is attached to the cutout portion 13a as shown in FIG.

Reference numeral 28 denotes a pin support for receiving a pin (not shown) of the hinge attached to the refrigerator main body side. As the hinge pin in front of the pin support 28 is pivoted, the refrigerating compartment door 2 is attached to the refrigerator main body 1 so that it can be opened and closed. Reference numeral 27 is a protrusion. This projection part 27 is provided in the direction which makes the rounding diameter of the rounding part 12 small, and as shown in FIG. 8, when the refrigerator main body side edge part P1 is seen from the door front side, it is not covered by this projection part. In addition, it has the effect | action which receives the pin support collar part 28a etc. of the pin support 28 previously. Therefore, the corner part of the makeup members 7 and 8 which cover the outer periphery of the door outer board 13 in a frame shape makes a half arc of 10 mm radius, for example.

Originally, the refrigerating compartment door 2 has the door 2 in order to reduce the trajectory type projecting dimension from the refrigerator main body 1 to the outside when the door is opened and closed, and to reduce the distance (gap) of the sink and the like adjacent to the refrigerator main body. It is provided at the end of the. For this reason, the attachment position of the said pin support 28 is caught by the rounding part 12 of the front part because it is close to the door side end part, and wants to install near a door front surface. Therefore, the color part 28a of the pin base 28 was a result of the attachment part being caught by the rounding part 12. As shown in FIG.

On the other hand, the refrigerator main body corner portion P2 (Fig. 7) on the opposite hinge side is naturally seen from the rounding portion 12. As a means for improving the appearance even a little, as shown in Fig. 7, even when the front R (radius) is increased, the inner R (radius) is made smaller as shown in the drawing, and the main body edge portion P2 appears. Means for reducing the size are taken.

These are all problems to be solved when the radius R which the side edge frame 5 and the makeup member 7 of the upper frame draw is large, and a new design is calculated | required.

This is because it is difficult for the existing equipment to round the corners on the side of the refrigerator main body even if a large rounding section 12 is provided on the corners on the door side.

In addition, as shown in FIG. 7 or FIG. 8, the side edge frame 10 and the upper frame 6 are connected to each of the upper frame 6 by using the projection member 29 provided on the side edge frame 10 side. It is performed by inserting into the coupling hole provided in the side.

By constructing as mentioned above, especially the front outer periphery of the refrigerating compartment door 2, the vegetable compartment door 3, and the freezer compartment door 4 has the cosmetic member 7 and 8 which the side edge frame 10 and the upper frame 6 have. (E.g., 5 to 10 mm wide), and the upper corner of the refrigerating compartment door 2 and the lower corner of the freezing compartment door 4 are both large rounded portions 12. You can get a new sense of unity with a sense of unity.

In addition, when the upper surface of the refrigerating compartment door 2 is closer to the height of the ceiling surface of the refrigerator main body 1 in order to improve the CER (effective contents: inner / outer dimensions), the refrigerator main body is made visible from the rounding part 12. The corner portions P1 and P2 on the side (1) can be partially hidden by the protrusions 27 and the like provided in the refrigerating chamber door rounding part 12, so that the CER improvement does not restrain the new design design of the refrigerator.

In addition, the outer edge of the door outer plate (13) is removed by the side member frame and shape of the upper frame to form a door having a large rounding part (12) to the rounding of the flat door outer plate (13). In addition to being able to make the door without preparing special parts for the rounding of the outer plate 13, the door outer plate also does not require many bending and throttling, so there is no factor such as deformation, and the refrigerator door can be simplified with simple equipment. It can be made.

In addition, the present invention, the handle attachment structure is fixed to the fixing member (17a, 17b) by the adhesive force of the foamed heat insulating material (15) and at the same time the fixing portion 17 of the cosmetic member 7 and the door outer plate 13 of the side edge frame ) Is fixed mechanically without the use of screws, etc., and thus, as compared with the conventional example, which relies only on the adhesive performance of the foam insulation 15, it is obvious that the screws are not used. good. In addition, since the handle 16 has a structure that does not overlap the makeup member 7 of the side edge frame 10, the frame made by the side edge frame 10 is not divided in the middle.

In addition, the rib 22 for enlarging the adhesive area of the fixing part 17 in the adhesive part with the foamed heat insulating material 15 of the fixing part 17 of the handle 16 is provided on the opposite side to which the handle part 18 is attached. By providing the handle 16, the handle 16 is conventionally increased and becomes substantially solid.

In addition, in the refrigerator door, the core 23 installed for the purpose of preventing deformation of the door is attached to accurately pull the first fixing member 17a of the handle against the side edge frame to promote attachment of a predetermined position. ) Is not attached to the door by bending.

According to the present embodiment described above, the refrigerator door is filled with foam insulation in the space created by the side edge frame, the upper and lower frames, the door outer plate and the door inner plate, and the frame is integrally fixed to the door outer plate, the door inner plate, and the like. Thus, the door outer plate is a door outer plate having a large rounding part at both upper edges, and the side edge frame is a side edge frame having a rounding part covering the rounding part of the door outer plate, and the upper surface position of the upper frame is Since the projections are designed to fit roughly to the ceiling and hide the corners of the refrigerator body at the rounding of the side edge frame, design-first design can be achieved while improving the CER (internal efficiency: internal / external dimensions). It is.

Further, since the protrusions provided in the side edge frame rounding part receive the color part of the pin support, the color part of the pin support does not become unstable by the rounding part.

Further, a foam insulation is filled in the space formed by the side edge frame, the upper and lower frames, the door outer plate and the door inner plate having a makeup member surrounding the outer circumference of the door outer plate, and the door outer plate, the door inner plate and the handle side edges. In the refrigerator door which solidified the frame etc., the handle consists of a fixed part and a handle part, and the fixed part has the 1st fixing member which follows at least the back side of the makeup member, and the side member side of a side edge frame, and the door outer board narrowing. Since it is comprised by the 2nd fixing member which has a branch, it adheres firmly by borrowing the adhesive force of a foam heat insulating material, and the mechanical strength of a side edge frame and a door outer board, without using a screw.

In addition, by making the first fixing member of the handle into a U-shape along the entire side of the foamed heat insulating material side shape of the side edge frame, a state in which the handle is attached without a turn of the urethane foam is obtained between the first fixing member and the side edge frame. Therefore, it is possible to solve the problem that the handle does not become a predetermined attachment state after filling the urethane foam.

Further, the first fixing member of the handle is a U-shaped shape along the entire side of the foam insulation material side shape of the side edge frame, and the rear member positioned on the door inner plate side of the fixing member and the plurality of ribs that enlarge the bonding area. Since a core is arrange | positioned at, the problem of deformation | transformation (overturning) of the fastening part (1st fastening member) of a handle by heat at the time of urethane foam foaming can be eliminated.

According to the present invention, it is possible to provide a refrigerator in which the shape of the refrigerator door can be made good in design while improving the CER (effective content: internal / external dimensions).

Moreover, according to this invention, the refrigerator which can reliably attach and fix a handle can be provided using the adhesive force of a foam heat insulating material, the mechanical strength of a side edge frame, and a door outer board.
