(first embodiment)
Fig. 1 is an overall front view of a refrigerator 100 of the present embodiment. Referring to fig. 1, a refrigerator 100 is configured by, for example, a main body 101 and doors 102L and 102R. The main body 101 includes a main refrigerating space 103, a freezing space 105, a vegetable accommodating space 106, a fruit accommodating space 107, an ice storage space 108, and the like. In the present embodiment, a refrigerated space (chilled space)104 is provided in the main refrigerated space 103. A cold air duct 131 is formed on the rear surface of the main refrigerating space 103, and air cooled by an unillustrated evaporator is supplied into the main refrigerating space 103 from cold air duct holes 131X and 131X. The main body 101 is formed by filling a heat insulator such as a foam heat insulator between the inner box 110 and an outer box 120 described later.

Fig. 3 is a front view showing the inner box 110 of the refrigerator 100 of the present embodiment. Fig. 4 is an enlarged front perspective view showing an upper portion of the inner box 110 of the refrigerator 100 according to the present embodiment. Referring to fig. 1 to 4, a cool air duct space 111 is formed in the vertical direction at the left and right center portions of the back surface 110B of the inner box 110. A concave-convex surface 116 in a shape of a convex strip extending in the up-down direction is formed on the left side of the cold air duct space 111 on the back surface 110B of the inner box 110. A vertically extending convex-stripe-shaped concave-convex surface 117 is also formed on the right side of the cold air duct space 111 on the back surface 110B of the inner box 110. A plurality of ribs 112, 112 … for holding a plurality of shelves are formed on the side surfaces 110L, 110R of the inner box 110.
Fig. 5 is an enlarged front view showing upper portions of the inner box 110 and the outer box 120 of the refrigerator 100 according to the present embodiment. Fig. 6 is an arrow sectional view a-a of fig. 3. Fig. 7 is an arrow sectional view B-B of fig. 4 with respect to only an upper portion of the inner case 110. Referring to fig. 5 to 7, in the present embodiment, a plurality of concave- convex surfaces 116 and 117 in a shape of a protruding bar extending in the up-down direction are formed on both left and right sides of an upper portion of a back surface 110B of an inner box 110 of a refrigerator 100. Further, a plurality of concave-convex surfaces 118 in a shape of a bar extending in the front-rear direction are formed also on the rear portion of the upper surface 110A of the inner box 110 of the refrigerator 100.
The plurality of concave- convex surfaces 116 and 117 are formed into a wave shape when viewed in a plane cross section (see fig. 8). The plurality of concave-convex surfaces 118 are formed in a wavy shape when viewed in front cross section.
In other words, a plurality of convex portions 116A and 116A … and concave portions 116B and 116B … are formed alternately in the vertical direction on both left and right sides of the upper portion of the back surface 110B of the inner box 110 of the refrigerator 100. In addition, a plurality of convex portions 116A, 116A … and concave portions 116B, 116B … are formed in the front-rear direction on the rear portion of the upper surface 110A of the inner box 110 of the refrigerator 100.
In other words, a corrugated surface including a plurality of ridges 116A and 116A … and valleys 116B and 116B … is formed in the vertical direction on the rear surface 110B of the inner box 110 of the refrigerator 100. A wave-plate-shaped surface including a plurality of peak portions 116A and 116A … and valley portions 116B and 116B … is formed in the front-rear direction on an upper surface 110A of an inner box 110 of refrigerator 100.
Fig. 8 is an arrow C-C sectional view of fig. 3, which is a view of the left and right center portions of the inner box 110, that is, portions where the concave and convex surfaces 116 and 117 are formed. Referring to fig. 8, in the present embodiment, each of the plurality of uneven surfaces 116 and 117 includes a plurality of regions having different uneven intervals. In the present embodiment, the interval between the irregularities at the left and right center portions of the inner box 110 is narrow, and the interval between the irregularities increases toward the left and right ends of the inner box 110.
More specifically, the interval between the irregularities at the right and left center portions, i.e., at the upper portion of cold air duct 131, is 15 mm. The interval between the concave-convex surfaces having the widest interval is set to be shorter than twice the interval between the concave-convex surfaces having the narrowest interval.
As shown in fig. 17, refrigerator 100 is equipped with refrigeration cycle 140 including compressor 141, evaporator 142, fan 143, and the like. The cooling capacity of the refrigerator can be controlled by the number of revolutions of the compressor. In addition, the number of revolutions of the compressor directly affects the power consumption of the refrigerator. Therefore, in recent years, the number of rotations of the compressor is more controlled precisely in a wider range, and both appropriate cooling and power saving are achieved. Since the frequency of vibration of the compressor depends on the number of revolutions of the compressor, vibration covering a wider range of frequencies is transmitted to the inner case 110 than ever.
In the inner box 110 of the present embodiment, as described above, the wall surface 110A or 110B is formed with the uneven surface, and the area in which the wall surface of the inner box 110 becomes a flat surface is reduced. Since the wide flat surface resonance frequency is low, there is a possibility of resonance with vibration at a low frequency occurring when the compressor is rotated at a lower speed, but in the inner case 110 of the present embodiment, the area where the wall surface of the inner case 110 becomes a flat surface is reduced, and resonance at a low frequency due to a flat surface is suppressed.
As described above, the inner box 110 of the present embodiment includes a plurality of regions having different intervals between the irregularities. The wall surface of the inner box 110, in which the interval between the irregularities is constant, is a wall surface having a wide area having a specific resonance frequency depending on the interval between the irregularities. Therefore, the inner case 110 has a resonance frequency f as shown in FIG. 90Has a vibration characteristic with a large peak.
As a result, as shown by the broken line in fig. 10, the compressor etc. is operated at a specific rotation number and at the resonance frequency f0In the case of vibration, the vibration is transmitted to the inner box 110 via the evaporator or the like, and large vibration and noise are generated due to resonance. Therefore, there is a problem that the rotation number of the compressor is controlled so as to avoid the specific rotation number, and the most appropriate rotation number of the compressor cannot be freely set in order to achieve both appropriate cooling and power saving.
However, in the inner box 110 of the present embodiment, the intervals between the uneven surfaces 116 and 117 are not the same, and therefore the wall surface of the inner box 110 is an assembly including a plurality of narrow regions each having a different resonance frequency depending on the uneven intervals. Therefore, the inner case 110, as shown in FIG. 11, includes a resonance frequency f0’~f0"dispersive vibration characteristics. As a result, even if vibration from the compressor or the like is transmitted to the inner box 110 via the evaporator or the like, as shown by a solid line in fig. 10, it is possible to prevent generation of large vibration and noise at a specific vibration frequency. Therefore, even in a state where the compressor is in any rotational speed, the rotational speed of the compressor can be set to an optimum rotational speed that is less likely to generate large vibration and noise and that is compatible with both appropriate cooling and power saving.
The interval between the projections and recesses having the widest interval is set to be shorter than twice the interval between the projections and recesses having the narrowest interval. Resonance occurs not only when subjected to vibration of a frequency equal to the resonance frequency but also when subjected to vibration of a frequency that is an integral multiple of the resonance frequency. Therefore, when the interval between the wide irregularities is twice as large as the interval between the narrow irregularities, the region of the wide irregularities resonates when subjected to vibration of a frequency equal to the resonance frequency of the region of the narrow irregularities, and vibration and noise may increase at a specific vibration frequency. Therefore, by forming the interval between the concavities and convexities having the widest interval to be shorter than twice the interval between the concavities and convexities having the narrowest interval, it is possible to prevent resonance from occurring simultaneously in a plurality of regions including intervals between different concavities and convexities.
In the present embodiment, the plurality of uneven surfaces 116 and 117 of the inner box 110 are formed such that the interval between the left and right center portions of the inner box 110 is narrow and the interval between the left and right ends of the inner box 110 increases. The main body 101 of the refrigerator 100 is formed by injecting a foaming heat insulating agent from the back surface of the outer box 120 between the side walls 110L and 110R of the inner box 110 and the outer box 120, and filling the heat insulating material. At this time, the foamed heat insulating agent starts to be filled from the front (lower side in fig. 6) of the main body 101, and the foamed heat insulating agent goes around the rear (upper side in fig. 6) of the main body 101. In the present embodiment, since the irregularities of the irregular surfaces 116 and 117 at the left and right end portions of the inner box 110 are smoother than the irregularities of the irregular surfaces 116 and 117 at the left and right center portions of the inner box 110, the irregular surfaces 116 and 117 at the left and right end portions are less likely to interfere with the diffusion of the foaming heat insulating agent, and the foaming heat insulating agent can be filled into the left and right center portions of the back surface of the main body 101.
Further, since the interval between the concave and convex surfaces is increased toward the left and right ends of the inner box 110, the left and right ends are closer to the flat surface than the center portion. Therefore, the shadows of the illumination applied to the inside of the inner box 110 when reflected on the wall surfaces at the left and right ends are lighter than at the center, and the visibility of the stored objects stored at the left and right ends of the main body 101 is improved. Therefore, the visibility of the stored object can be improved while preventing large vibration and noise due to resonance.
(second embodiment)
In the first embodiment, the plurality of concave- convex surfaces 116, 117, and 118 are formed such that the concave-convex surface interval is narrow at the left and right center portions of the inner box 110 and the concave-convex surface interval is wider toward the left and right ends of the inner box 110. However, it is not limited to this scheme.
For example, the plurality of concave- convex surfaces 116 and 117 may be formed such that the concave-convex surface interval is wide at the left and right center portions of the inner case 110 and becomes narrow toward the left and right ends of the inner case 110. In the present embodiment, in order to reduce the degree of resonance with vibration generated from the compressor, other devices, and the like, it is preferable that the interval between the concave and convex surfaces having the widest interval is set to be shorter than twice the interval between the concave and convex surfaces having the narrowest interval.
(third embodiment)
Alternatively, as shown in fig. 12, the intervals between the plurality of concave- convex surfaces 116 and 117 may be irregular without regularity, as compared with the first and second embodiments. In the present embodiment, in order to reduce the degree of resonance with vibration generated from the compressor, other devices, and the like, it is preferable that the interval between the concave and convex surfaces having the widest interval is set to be shorter than twice the interval between the concave and convex surfaces having the narrowest interval.
(fourth embodiment)
The intervals between the concave- convex surfaces 116 and 117 do not necessarily need to be set in plural kinds. As shown in fig. 13, there may be only two kinds of intervals between the plurality of concave- convex surfaces 116 and 117. In the present embodiment, in order to reduce the degree of resonance with vibration generated from the compressor, other devices, and the like, it is preferable that the interval between the wide uneven surfaces is not an integral multiple of the interval between the narrow uneven surfaces.
(fifth embodiment)
As shown in fig. 14, the width of the right side inclination 116R … of the mountain of each of the plurality of concave- convex surfaces 116 and 117 may be different from the width of the left side inclination 116L …. In the present embodiment, in order to reduce the degree of resonance with vibration generated from the compressor, other devices, and the like, the width of the longest tilt is formed to be shorter than twice the width of the shortest tilt. Further, it is preferable that the total of the widths of a plurality of consecutive slopes does not become a multiple of the width of any one slope.
(sixth embodiment)
As shown in fig. 15 or 16, the longest slope 116T may be twice as long as the shortest slope 116S. In this case, in order to reduce the degree of resonance with vibration generated from the compressor, other devices, and the like, it is preferable that the width of each of the plurality of slopes is not a multiple of the width of any of the other slopes. Further, it is preferable that the total of the widths of a plurality of consecutive slopes does not become a multiple of the width of any one slope.
(seventh embodiment)
Further, the uneven surfaces 116 and 117 may be formed in a convex shape extending in one direction, and the uneven surfaces 116 and 117 may be used as reinforcing ribs.
Further, by forming the convex and concave surfaces 116 and 117 in a convex stripe shape from the back surface 110B to the top surface 110A, the bent portion, which is the connection portion between the back surface 110B and the top surface 110A, can be reinforced.
The uneven surfaces 116 and 117 are not limited to the wavy cross section, and may be grooves or uneven surfaces having a rectangular, trapezoidal, or circular arc cross section.

In the first to seventh embodiments, there is provided a refrigerator 100 including a compressor 141 operating a refrigeration cycle 140 and an inner box 110 receiving stored goods. The inner case 110 has a plurality of irregularities 116, 117, 118 formed on at least one of the wall surfaces 110B, 110A.
