Disclosure of Invention

However, in the case where the foam heat insulating material is provided between the door front panel and the door rear panel, the door front panel may warp due to foam pressure at the time of filling the foam. Even when a vacuum heat insulating material is provided between the door front panel and the door rear panel, the inside of the vacuum heat insulating material is depressurized, and the thickness thereof changes slightly due to a change in the outside air pressure or a change in the inside pressure. In a refrigerator door in which a glossy plate-like member such as a glass plate is used as a door front plate, mirror reflection occurs in the door front plate, and the posture of a user and surrounding scenery are easily reflected on the door front plate. In particular, when a plurality of refrigerator doors are arranged side by side in the vertical or horizontal direction, if the warpage generated in the door front is not uniform between the refrigerator doors, the warpage patterns of the images projected on the refrigerator doors may be different from each other, which may significantly impair the appearance of the refrigerator.

Accordingly, an object of the present invention is to provide a refrigerator door, comprising: in the refrigerator door with the door front plate on the surface, the door front plate is difficult to warp, the warp of the image mapped on the door front plate can be restrained, and the refrigerator with higher appearance quality can be obtained.

The refrigerator door according to the embodiment includes: the refrigerator door comprises a door front plate arranged on a surface part, a door rear plate arranged on the back surface of the door front plate, and a heat insulating material arranged between the door front plate and the door rear plate, wherein the refrigerator door seals an opening part of the refrigerator, and the front surface of the door front plate is provided with a concave part which is concave towards the rear side.

According to the above configuration, since the front surface of the door front panel has the concave portion recessed toward the rear side, even if there is a stress pressing from the rear side toward the front side, the door front panel is less likely to be deformed, and the door front panel is less likely to be warped. Therefore, the warping of the image projected on the door front plate of the refrigerator door can be suppressed, and a refrigerator with a high appearance quality can be obtained.

The push-pull rail attachment plate 26 is a metal member having a long length in the longitudinal direction, and includes one on each of the left and right sides for attaching: and a push-pull guide rail 6b for supporting the receiving container 6a provided at the rear side of the 2 nd freezing chamber door 6.

In this case, the door rear plate 27 is made of plastic, has a rectangular shape having substantially the same size as the door front plate 21, has recesses 27a for accommodating the push-pull rail attachment plates 26 on both left and right sides, and has a narrow opening portion 27b for accommodating the heat insulator 25 in a peripheral portion on the back side.

The peripheral edge portion on the back side of the door back plate 27 has a gasket attachment portion 27c (see fig. 1). The washer mounting portion 27c is hollow with the opening portion directed to the rear side. The inner (center) region is smooth with respect to the gasket mounting portion 27c provided on the door back plate 27 and the narrow opening portion 27 b.

The gasket 28 has an arrow-shaped insertion portion 28a attached to the gasket attachment portion 27c, and the gasket 28 is fixed so as to surround the peripheral edge portion of the door back plate 27. The gasket 28 includes, on the back surface side of the insertion portion 28 a: a hollow air cushion portion 28b for relaxing the impact at the time of door closing and enabling the gasket 28 to be brought into close contact with the refrigerator main body 1, a magnet 28c provided on the back side of the air cushion portion 28b and for magnetically attracting the refrigerator main body 1, and a fin rib portion 28d protruding further inward than the air cushion portion 28b and enabling the leakage of cold air from the refrigerator main body 1 to be more reliably prevented.

In this configuration, the front surface 21a of the glass plate constituting the door front plate 21 is provided with a recessed portion 21b recessed toward the rear side.

The vertical cross-sectional shape of the concave portion 21b in the present embodiment is linear and is not curved in the vertical direction, and the horizontal cross-sectional shape shown in fig. 1 is: the concave shape is recessed most largely toward the rear side at the widthwise center portion so as to be located more rearward from both the left and right side ends toward the widthwise center of the refrigerator main body 1.

The concave portion 21b is a curved surface formed by smoothly connecting arcs having a plurality of radii of curvature, and exhibits: a concave curved surface shape formed by a circular arc with a smaller curvature radius on the outer side in the width direction. As an example, the following can be made: a curved surface whose curvature radius changes in the order of 80mm, 800mm, 1000mm, 2000mm from the outer side of the refrigerator main body 1 in the width direction toward the center portion. In addition, in the present embodiment, the front surface 21a of the door front panel 21 is formed with: a shape in which the inclination angle with respect to a plane S perpendicular to the thickness direction of the door front panel 21 is relatively large at both left and right end portions and becomes smaller as it approaches the width direction center portion; the front surface 21a of the door front panel 21 is integrally formed with a concave portion 21 b.

The maximum angle of the inclination angle θ of the front surface 21a of the door front panel 21 with respect to the plane S (in the present embodiment, the inclination angles at the left and right end positions) is preferably 90 ° or less, more preferably 45 ° or less, and still more preferably 30 ° or less. The thickness t1 of the door front panel 21 provided at the bottom 21c of the concave portion 21b of the front surface 21a of the door front panel 21 (i.e., the thickness t1 of the door front panel 21 at the thinnest position) is set to: is larger than a distance t2 from the flat surface S to the bottom 21c of the concave shape (i.e., a concave amount t 2). In the present embodiment, the rear surface of the door front 21 provided with the upper color layer 30 is formed as follows: a flat surface having no irregularities.

The support frame 22 projects forward from the outer periphery of the support portion 31, and includes: a holding part 32 having a flange-like projecting tip end inward. The support frame 22 is adhesively fixed to the rear surface of the door front plate 21 by a double-sided tape 33 provided on the front surface of the support portion 31, and holds the peripheral edge portion of the door front plate 21 between the grip portion 32 and the support portion 31 in such a manner that the grip portion 32 covers the peripheral edge portion of the front surface of the door front plate 21 (i.e., the upper and lower edge portions and the left and right edge portions).

In the present embodiment, the present invention includes: since the recessed portion 21b having a concave shape is formed in which the front surface 21a of the door front plate 21 constituting the outer surface of the 2 nd freezing compartment door 6 is recessed toward the rear side, even if there is a stress pressing from the rear side toward the front side, the door front plate 21 is hardly deformed, and the door front plate 21 is hardly warped. Accordingly, the warping of the image projected on the door front plate 21 of the 2 nd freezing compartment door 6 can be suppressed, and a refrigerator with a high external appearance quality can be obtained.

In the present embodiment, the front surface peripheral edge portion of the door front plate 21 is covered with the grip portion 32 of the support frame 22, and therefore, damage and breakage of the door front plate 21 can be prevented.

Further, in the present embodiment, since the concave shape of the concave portion 21b provided on the front surface 21a is set to: since the thickness t1 of the door front panel 21 is greater than the recessed amount t2 of the concave shape, there is no problem that the door front panel 21 itself becomes too thin and the rigidity is lowered.

(modification 1)

In the above embodiment, the case where the recessed portion 21b having a recessed shape is provided in which the front surface 21a of the door front plate 21 constituting the outer surface of the 2 nd freezing compartment door 6 is recessed toward the rear side has been described, but

other refrigerator doors

2, 3, 4, and 5 may be provided with a recessed portion having a recessed shape in which the front surface of the door front plate constituting the outer surface is recessed toward the rear side.

As in the present embodiment, by providing the recessed portion of the recessed shape recessed toward the rear side on the front surface of the door front plate constituting the outer surface of all the

refrigerator doors

2, 3, 4, 5, 6 provided in the refrigerator main body 1, the door front plate is less likely to warp between the

refrigerator doors

2, 3, 4, 5, 6, and thus the warp of the mapped image is suppressed, and a refrigerator of high appearance quality can be obtained.

In particular, when the recessed portion is provided on the front surface of the door front plate of a plurality of vertically aligned refrigerator doors, the front surface of the door front plate of the vertically aligned refrigerator doors is preferably: the vertical sectional shape is set to be linear, and the horizontal sectional shape is set to be the same shape as that of the refrigerator doors which are arranged side by side up and down. At this time, in the case where a plurality of refrigerator doors are arranged side by side in the width direction of the refrigerator main body 1 as the ice making chamber door 4 and the 1 st freezing chamber door 5, it is preferable that the horizontal sectional shape of the front surface of the door front plate of the ice making chamber door 4 and the 1 st freezing chamber door 5 takes a continuous concave curved shape and is a shape in conformity with the horizontal sectional shape of the front surface of the door front plate of the

refrigerator doors

2, 3, 6 provided above or below these doors 4, 5. In this way, the horizontal cross-sectional shape of the front door panel of the vertically aligned refrigerator doors is made to have the same shape, and the front surface of the refrigerator is uniformly mapped, thereby obtaining a refrigerator with a higher appearance quality.

(modification 2)

In the above embodiment, although the horizontal sectional shape of the concave portion 21b provided in the door front plate 21 of the 2 nd freezing compartment door 6 is set to: a concave curved surface shape formed by smoothly connecting a plurality of arcs with curvature radius; the vertical sectional shape of the front surface 21a of the door front 21 is provided linearly, but the present invention is not limited thereto as long as a shape recessed toward the rear side is provided on the front surface 21a of the door front 21. For example, the horizontal cross section may be linear, and the vertical cross section may be concave toward the rear side, or both the horizontal cross section and the vertical cross section may be concave toward the rear side. The concave portion 21b of the front surface 21a of the door front panel 21 is a curved surface formed by smoothly connecting a plurality of arc surfaces having different radii of curvature, but is not limited to this, and may be: the concave shape may be a combination of a plurality of planes having different inclination angles with respect to a plane perpendicular to the thickness direction of the door front panel 21, or a concave shape formed by a single circular arc.

(modification 3)

In the above-described embodiment, the refrigerator in which the refrigerating chamber 7, the vegetable chamber 8, the ice making chamber 9, the 1 st freezing chamber 10, and the 2 nd freezing chamber 11 are provided in the refrigerator main body 1 and the

refrigerator doors

2, 3, 4, 5, and 6 are provided in the

respective storage chambers

7, 8, 9, 10, and 11 has been described, but for example, in a so-called double door refrigerator having a refrigerating chamber, a freezing chamber, and 2 doors provided in these storage chambers, a concave portion of a concave shape that is concave toward the rear side may be provided on the front surface of a door front plate constituting the outer surface of the refrigerator door.

(embodiment 2)

Next, embodiment 2 will be described with reference to fig. 4 to 7. The same components as those in embodiment 1 are denoted by the same reference numerals, and description thereof will be omitted.

In embodiment 1 described above, the case where the front surface peripheral edge portion of the door front plate 21 is covered with the grip portion 32 of the support frame 22 has been described, but in the present embodiment, the front surface peripheral edge portion of the door front plate 212 is exposed to the outside when viewed from the front.

That is, as shown in fig. 4, the support frame 222 includes: a protrusion 342 protruding from the outer peripheral portion of the support portion 312 that fixes the back surface of the door front plate 212 toward the front side along the peripheral surface of the door front plate 212. The tip of the projection 342 is not bent inward and terminates as in embodiment 1. Accordingly, when viewed from the front, the front surface peripheral edge of the door front plate 212 is not covered by the front end portion of the protruding portion 342, but is exposed to the outside.

In the present embodiment, the door front plate 212 is exposed over the entire surface (front surface) of the refrigerator door 6, and thus the appearance quality of the refrigerator can be improved.

In the present embodiment, as shown in fig. 5, in order to make the thickness of the front surface peripheral edge portion of the door front plate 212 thinner as the front surface peripheral edge portion approaches the peripheral edge portion, a chamfered surface 212g may be formed on the front surface peripheral edge portion of the door front plate 212 by linearly cutting a corner portion of the front surface peripheral edge portion of the door front plate 212, by cutting a corner portion of the front surface peripheral edge portion of the door front plate 212 in an arc shape, or the like. Accordingly, damage or breakage of the door front panel 212 can be suppressed. In the case of cutting the corner portion of the front surface peripheral edge portion of the door front plate 212, although the front surface peripheral edge portion 212e of the door front plate 212 may be located forward with respect to the protruding portion 342 of the support portion 312, it is preferable that the front surface peripheral edge portion 212e is located rearward with respect to the protruding portion 342 of the support portion 312 as shown in fig. 5, and it is preferable that the corner portion 212f located inward from the front surface peripheral edge portion 212e is located by cutting the corner portion of the front surface peripheral edge portion of the door front plate 212 as shown in fig. 6: is located rearward of the protruding portion 342 of the support portion 312.

In this way, since the front peripheral edge 212e of the door front plate 212 is positioned more rearward than the protruding portion 342, the front peripheral edge 212e of the door front plate 212, which is likely to be damaged, can be covered from the outside by the support frame 222, and the occurrence of damage or breakage can be suppressed. In addition, since the corner portion 212f located inward of the front peripheral edge 212e is located rearward of the protruding portion 342, the corner portion 212f is less likely to be touched by an article, and damage or breakage of the door front panel 212 can be further suppressed.

As shown in fig. 7, the support frame 222 may not have a protruding portion protruding from the outer peripheral portion of the support portion 312 toward the front side, but an outer side surface (outer peripheral surface) of the support frame 222 and an outer side surface (outer peripheral surface) of the door front plate 212 may be continuous, and the outer side surface of the door front plate 212 may be entirely exposed. In this case, since the entire outer side surface of the door front panel 212 is exposed to the outside except the front surface, the area of the door front panel 212 exposed to the outside is increased, and the appearance quality of the refrigerator can be improved.

Other configurations and operational effects are the same as those of embodiment 1, and detailed description thereof is omitted.

(embodiment 3)

Next, embodiment 3 will be described with reference to fig. 8 and 9. The same components as those in embodiment 1 are denoted by the same reference numerals, and description thereof will be omitted.

In the above embodiments, although: in the case where the front surface 21a of the door front plate 21 is entirely formed into the concave portion 21b so that the front surface 21a of the door front plate 21 is located at the rear side position as the center in the width direction of the refrigerator main body 1 is closer to both the left and right side ends, in the present embodiment, the concave portion 213b is provided on the front surface 213a of the door front plate 213, and the flat portion 213d parallel to the plane S is provided on a part of the door front plate 213.

For example, as shown in fig. 8, a flat portion 213d parallel to a plane S perpendicular to the thickness direction of the door front plate 213 is provided at the left and right end portions or the upper and lower end portions of the door front plate 213, and a concave portion 213b is provided inside the flat portion 213d, or as shown in fig. 9, a flat portion 293d parallel to the plane S may be provided at the bottom 293c of the concave portion 293b, and the concave portion 293b may be provided at the front surface 293a of the door front plate 293.

In addition, in order to receive an operation by a user or to detect an approach of the user, a detection portion for detecting a change in the electrostatic capacitance may be provided in the refrigerator door, and in this case, as shown in fig. 8 and 9, it is preferable that a detection portion 50 capable of detecting a change in the electrostatic capacitance be provided on the rear surface side of the

flat portions

213d and 293d provided in the door

front plates

213 and 293, that is, at a position facing the

flat portions

213d and 293d in the thickness direction of the door

front plates

213 and 293.

By providing the detection unit 50 on the rear surface of the

flat portion

213d, 293d of the door

front plate

213, 293 in this manner, the user can touch and operate the

flat portion

213d, 293d, thereby improving operability, and when a plurality of detection units 50 are provided, the distance from the

front surface

213a, 293a of the door

front plate

213, 293 touched and operated by the user to each detection unit 50 is constant, so that the detection sensitivity of each detection unit 50 can be easily set.

(embodiment 4)

Next, embodiment 4 will be described with reference to fig. 10. The same components as those in embodiment 1 are denoted by the same reference numerals, and description thereof will be omitted.

In each of the above embodiments, the front surface of the door front plate is provided with a concave portion recessed toward the rear side, and the rear surface of the door front plate is configured as a plane perpendicular to the thickness direction of the door front plate, but in the present embodiment, as shown in fig. 10, a concave-shaped rear surface concave portion recessed toward the rear side is formed so that the rear surface 294g of the door front plate 294 is substantially parallel to the front surface 294 a.

Although the door front plate 294 is adhesively fixed to the front surface of the support portion 314 provided in the support frame 224, the front surface 314a of the support portion 314 is formed as follows: along with the concave shape of the rear surface 294g of the door front panel 294.

In the present embodiment, even if the front surface 294a of the door front 294 is provided with the concave portion 294b that is concave toward the rear side, the thickness of the door front 294 is not reduced, and therefore, even if the door front 294 receives a stress that presses the door front from the rear side, the door front 294 is more unlikely to warp, and a refrigerator with a high external appearance quality can be obtained.

In addition, in the present embodiment, the front surface 314a of the support portion 314 of the support frame 224 supporting the door front plate 294 is formed as: along the concave shape of the rear surface 294g of the door front plate 294, and the front surface 314a is adhesively fixed to the rear surface 294g of the door front plate 294 in a surface contact state, and therefore, the door front plate 294 can be firmly fixed to the support frame 224.

(embodiment 5)

Next, embodiment 5 will be described with reference to fig. 11. The same components as those in embodiment 1 are denoted by the same reference numerals, and description thereof will be omitted.

In the above embodiments, the case where each storage room partitioned by the refrigerator main body 1 is closed by one refrigerator door has been described, but the front surface opening of the storage room may be closed by 2 refrigerator doors arranged side by side in the left-right direction.

For example, as shown in fig. 11, the front opening of the refrigerating compartment 7 is closed by the side-by-side 2

doors

2a and 2 b. Of the 2

doors

2a and 2b, the left door 2a on the left side in front view openably closes the left side of the front opening of the refrigerating chamber 7 so that the left end portion of the left door 2a is supported by the refrigerator main body 1 so as to be rotatable via the upper hinge 12 a. The right door 2b on the right side closes the right side of the front opening of the refrigerating chamber 7 in an openable and closable manner so that the right end portion of the right door 2b is supported by the refrigerator main body 1 in a rotatable manner by the upper hinge 12b when viewed from the front.

Even in this embodiment, since the recessed portions 215ab and 215bb recessed toward the rear side are provided on the front surface 215aa of the front door panel 215a of the left door 2a and the front surface 215ba of the front door panel 215b of the right door 2b, respectively, the

front door panels

215a and 215b are less likely to be distorted, and therefore, the distortion of the image projected on the

front door panels

215a and 215b can be suppressed, and a refrigerator of high external appearance quality can be obtained.

In the present embodiment, it is preferable that the front surface 215aa of the door front plate 215a of the left door 2a and the front surface 215ba of the door front plate 215b of the right door 2b are formed as follows: a concave curved surface shape smoothly continuous in the horizontal direction. Accordingly, smooth and continuous images are mapped on the

door front plates

215a and 215b of the left door 2a and the right door 2b arranged side by side in the left-right direction, and a refrigerator with high appearance quality can be obtained.

In this case, the

refrigerator doors
