[0009] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

[0010] <First embodiment> In this embodiment, a refrigerator having a speaker on the top surface of the refrigerator main body will be described as an example of a refrigerator according to one aspect of the present invention.

[0011] <Overall configuration of refrigerator> 1 shows the configuration of the front side of a refrigerator 1 according to this embodiment. The outer shape of the main body of the refrigerator 1 is mainly formed by a heat-insulating box (refrigerator main body) 10. The refrigerator 1 has a first refrigerator compartment on the upper level, a second refrigerator compartment (vegetable compartment) on the middle level, and a freezer compartment on the lower level.

[0012] The configuration and arrangement of each storage compartment in the refrigerator 1 are not limited to those described above. The configuration and arrangement of each storage compartment can be changed as appropriate depending on the capacity, purpose, etc. of the refrigerator.

[0013] Moreover, a refrigerator compartment door 11 is provided in the first refrigerator compartment on the upper level. The refrigerator compartment door 11 is a double-hinged door that can be opened and closed from either the left or right end. Therefore, grips 82 that function as handles when opening and closing the refrigerator compartment door 11 are provided on both the left and right ends of the refrigerator compartment door 11. Specifically, the left grip 82a is provided on the left end of the refrigerator compartment door 11. Moreover, the right grip 82b is provided on the right end of the refrigerator compartment door 11.

[0014] The second refrigerator compartment (vegetable compartment) on the middle level is provided with a pull-out refrigerator compartment door 13. The freezer compartment on the lower level is provided with a pull-out freezer compartment door 14.

[0015] The configuration of each door of the refrigerator 1 is not limited to the above. For each storage compartment door, a door that can be opened and closed from both the left and right sides, a double door door, a door that can be opened and closed from either the left or right end, a drawer door, etc. can be appropriately adopted depending on the structure, purpose, position, etc. of the storage compartment.

[0016] In this embodiment, the surface on which the door is provided is defined as the front surface (front face) of the refrigerator. Based on the front surface as a reference, the respective surfaces of the refrigerator 1 and the insulated box body 10 are defined as the top surface, side surface, rear surface (rear surface), and bottom surface based on the positions where the refrigerator 1 would be when installed in a normal state. Also, when the refrigerator 1 (or the insulated box body 10, the upper mounting member 12, etc.) is viewed from the front side, the side located to the left is referred to as the left side of the refrigerator 1, etc., and the side located to the right is referred to as the right side of the refrigerator 1, etc.

[0017] An upper mounting member 12 is disposed on the top surface 10a of the heat-insulating box 10. A speaker (electronic component) 70, hinge reinforcement parts 81 (81a and 81b), and the like are provided within the upper mounting member 12 (see FIG. 5).

[0018] The speaker 70 can emit sounds such as various notification sounds or voice messages to the user. In this embodiment, the speaker 70 is configured to emit sounds in the horizontal direction, that is, toward the side (specifically, forward). In this embodiment, a speaker is given as an example of an electronic component, but the electronic component is not limited to this and may be a microphone or a sensor component that needs to detect the outside air (for example, a temperature or humidity sensor, a human sensor, etc.).

[0019] Hinge reinforcement portion 81 is made up of left-side hinge reinforcement portion 81a which constitutes the left-side hinge portion of refrigerator 1, and right-side hinge reinforcement portion 81b which constitutes the right-side hinge portion of refrigerator 1. Each of hinge reinforcement portions 81a and 81b has a hinge pin or the like attached thereto to constitute the hinge portion, and includes a metal plate member to improve the strength of the hinge portion.

[0020] <Configuration of upper mounting member> Next, the configuration of the upper mounting member 12 will be described. Fig. 2 shows the appearance of the upper mounting member 12. Fig. 3 shows the configuration of the upper mounting member 12 as viewed from above. Figs. 2 and 3 also show the top surface 10a of the insulating box 10. Fig. 4 shows the configuration of the upper mounting member 12 as viewed from the front (front). Figs. 5 and 6 show the internal configuration of the upper mounting member 12. Figs. 5 and 6 are views of the upper mounting member 12 with the cover member 22 removed.

[0021] The outer shape of the upper mounting member 12 is mainly composed of a base member 21 and a cover member 22. The base member 21 and the cover member 22 are formed, for example, by processing a resin material into a predetermined shape. The base member 21 mainly constitutes the lower surface (bottom surface) of the upper mounting member 12. The cover member 22 mainly constitutes the upper surface of the upper mounting member 12. The cover member 22 is arranged so as to cover the upper portion of the base member 21.

[0022] Inside upper mounting member 12, the outer shape of which is formed by base member 21 and cover member 22, speaker 70, hinge reinforcement parts 81 (81a and 81b), etc. are arranged (see FIG. 5).

[0023] In another embodiment, a configuration is also possible in which the base member 21 is not provided, and the speaker 70 and the like are directly installed on the upper surface of the insulating box 10, with the cover member 22 provided to cover these.

[0024] The speaker 70 is disposed on the rear side of the upper mounting member 12. Specifically, the speaker 70 is disposed approximately in the center in the left-right direction on the rear side of the base member 21. By disposing the speaker 70 approximately in the center in the left-right direction on the rear side of the base member 21, sound can be output from the speaker 70 (specifically, the speaker hole 31) toward a person standing in the center in front of the refrigerator 1.

[0025] The speaker 70 is connected to a control board (not shown) on the refrigerator main body side and the like via a harness 71. The harness 71 is disposed on the base member 21 inside the upper mounting member 12. For example, the harness 71 extends from the rear side of the speaker 70 to the left side, passes through the speaker 70 and the left side of the opening 33, and is connected to a connector at the left end of the base member 21 for connection to the outside of the upper mounting member 12 (see FIG. 5).

[0026] The hinge reinforcement portion 81 is disposed on the front side of the base member 21 and extends in the left-right direction. The hinge reinforcement portion 81 is formed of a material having a relatively high rigidity, such as a metal. In this embodiment, the hinge reinforcement portion 81 is formed by processing a metal plate into a predetermined shape.

[0027] The hinge reinforcement portion 81 has a left hinge reinforcement portion 81a and a right hinge reinforcement portion 81b.

[0028] The left hinge reinforcement part 81a is disposed at the left hinge part 80 (i.e., the left end part on the front side of the upper mounting member 12). Specifically, the left hinge reinforcement part 81a is disposed at the front left corner part of the bottom surface of the base member 21, and the left hinge part 80 is exposed downward through an opening provided in the bottom surface of the base member 21.

[0029] The right hinge reinforcement part 81b is disposed at the left hinge part 80 (i.e., the right end part on the front side of the upper mounting member 12). Specifically, the right hinge reinforcement part 81b is disposed at the front right corner part of the bottom surface of the base member 21, and the right hinge part 80 is exposed downward through an opening provided in the bottom surface of the base member 21.

[0030] <Speaker and peripheral configuration> Next, the speaker 70 and its surrounding structure will be described in more detail. Fig. 7 shows the structure around the speaker 70 inside the upper mounting member 12. Fig. 7 is a diagram showing the cross-sectional structure of the AA line portion of the upper mounting member 12 shown in Fig. 4 (i.e., the position where the drainage hole 32 is formed).

[0031] As shown in Fig. 7, a sunken space 50 is provided in front of the speaker 70 by recessing the cover member 22. A drainage mechanism 60 is provided in this sunken space 50 to prevent water and the like from entering the speaker 70. Fig. 8 shows the structure around the sunken space 50 in which the drainage mechanism 60 is provided. Fig. 8 is a diagram showing a cross-sectional configuration of the portion of the upper mounting member 12 shown in Fig. 3 taken along line BB.

[0032] The speaker 70 has a sound producing unit 72. The sound producing unit 72 is disposed on one side surface of the main body of the speaker 70. In this embodiment, the sound producing unit 72 is provided on the side surface of the main body of the speaker 70 that is located on the same side as the front surface of the refrigerator 1 and the upper mounting member 12.

[0033] Since sound producing unit 72 is disposed on one side of the main body of speaker 70, sound producing unit 72 can emit sound in a lateral direction. Here, lateral means the horizontal direction when refrigerator 1 is placed on a horizontal surface. Here, lateral is used to mean the front direction, rear direction, right direction, left direction, and at least one diagonal direction between these directions.

[0034] In this embodiment, since the sound generating unit 72 is provided on the front side of the main body of the speaker 70, the speaker 70 can emit sound from the front of the refrigerator 1 toward the front, as shown by the arrow P in FIG. 7.

[0035] As shown in Fig. 7, the upper part of the speaker 70 is covered with a cover member 22. A vertical wall 31a, which is a part of the cover member 22, is provided on the front side of the sound generating portion 72. A speaker hole 31 is formed in this vertical wall 31a at a position corresponding to the sound generating portion 72 (an area overlapping with the sound generating portion 72 in a front view). The speaker hole 31 is composed of a plurality of small holes. The speaker hole 31 is an example of a communication portion.

[0036] An inclined portion 73 is provided between the speaker 70 and the speaker hole 31. The inclined portion 73 extends from the sound generating portion 72 side of the speaker 70 toward the speaker hole 31 side. The inclined portion 73 has a gradient that slopes downward from the sound generating portion 72 side toward the speaker hole 31 side (see FIG. 7).

[0037] Guide portions 74 are provided on both the left and right sides of the inclined portion 73. That is, the guide portions 74 are disposed at positions facing each other with the inclined portion 73 therebetween. The guide portions 74 are formed higher than the inclined surface of the inclined portion 73. As shown in FIG. 6, side walls are formed by the guide portions 74 and 74 on both the left and right sides of the inclined portion 73. With this configuration, it is possible to prevent the sound emitted from the sound generating portion 72 of the speaker 70 from diffusing to both the left and right sides. Therefore, the sound emitted from the sound generating portion 72 can be efficiently guided to the speaker hole 31.

[0038] A drainage mechanism 60 is provided on the front side of the speaker 70 (i.e., the side of the speaker 70 where the speaker hole 31 is located). The drainage mechanism 60 is a mechanism for quickly draining liquid, such as water, onto the upper surface of the cover member 22 and onto the upper surface 10a of the heat-insulating box 10 below the base member 21, to prevent the liquid from penetrating into the upper mounting member 12. This makes it possible to prevent the liquid from reaching the speaker 70.

[0039] The drainage mechanism 60 has a drainage hole 32 and an opening 33. The drainage hole 32 is formed in the cover member 22. The opening 33 is formed in the base member 21. The drainage hole 32 and the opening 33 are disposed at positions where they at least partially overlap when viewed from above.

[0040] The drainage holes 32 are formed in the bottom surface of the dug space 50 formed by recessing a part of the cover member 22. As shown in Fig. 3, in this embodiment, the drainage holes 32 are configured as two holes aligned side by side, but the configuration of the drainage holes 32 is not limited to this.

[0041] The opening 33 is disposed in front of the speaker 70. As shown in Fig. 5, in this embodiment, the opening 33 has a substantially rectangular shape in a top view. The opening area of ​​the drainage hole 32 is disposed so as to fall within the range of the opening area of ​​the opening 33 in a top view.

[0042] A surrounding wall 35 is formed on the upper surface 21a of the base member 21 (the surface facing the inside of the upper mounting member 12) so as to surround the periphery of the opening 33 (see Figs. 5 and 6). By providing such surrounding wall 35, even if a part of the liquid passing through the drainage hole 32 and the opening 33 seeps into the inside of the upper mounting member 12, it is possible to prevent the liquid from entering the inside of the surrounding wall 35.

[0043] Therefore, it is possible to prevent the components and wiring (such as the harness 71) disposed inside the surrounding wall 35 from getting wet.

[0044] 7 and 8, the dug space 50 is formed so that the drainage hole 32 is positioned to overlap the opening 33 in the vertical direction. This ensures a large difference in height between the speaker 70 and the speaker hole 31, and the drainage hole 32, and prevents water from entering through the speaker hole 31.

[0045] Also, a gap G is provided between a lower surface 22f (the surface on the inner side of the upper mounting member 12) of the cover member 22 around the drainage hole 32 and an upper surface 21a (the surface on the inner side of the upper mounting member 12) of the base member 21 (see FIG. 8). That is, the opening 33 of the base member 21 is not blocked by the lower surface 22f of the cover member 22.

[0046] Water that passes through the drainage holes 32 passes through the space between the bottom surface of the base member 21 and the top surface 10a of the heat-insulating box 10 and is discharged around the upper mounting member 12, but if it is desired to make the upper mounting member 12 low-profile, it may be difficult to provide a sufficient height for the space between the bottom surface of the base member 21 and the top surface 10a of the heat-insulating box 10. In this case, the surface tension of the water that has entered this space blocks the space between the bottom surface of the base member 21 and the top surface 10a of the heat-insulating box 10, making it difficult for the air in this space to be discharged, resulting in a problem that the water in this space becomes difficult to move.

[0047] In this embodiment, in order to solve this problem, the above-mentioned gap G is provided to provide an area around the drainage hole 32 that communicates the space between the lower surface of the base member 21 and the upper surface 10a of the heat-insulating box 10 with the inside of the upper mounting member 12, and the air in the space between the lower surface of the base member 21 and the upper surface 10a of the heat-insulating box 10 can be discharged into the upper mounting member 12, making it easier to move water in the space. Note that since this gap G is formed outside the dug-down space 50, the gap G is not blocked even if water accumulates in the dug-down space 50. This makes it possible to prevent liquid that has entered the inside of the upper mounting member 12 from the drainage hole 32, the speaker hole 31, etc. from continuing to accumulate inside without being discharged.

[0048] 9, protrusions 34 may be provided on the underside 22f of the cover member 22 around the drainage hole 32. The protrusions 34 are provided, for example, on both the left and right sides of the drainage hole 32. Providing such protrusions 34 can prevent the drainage hole 32 from coming into contact with the upper surface 10a of the insulating box 10 and being blocked, even when the cover member 22 is pressed from above. It is preferable that the gap G is maintained even when the protrusions 34 are in contact with the upper surface 10a.

[0049] Since the upper mounting member 12 has the drainage mechanism 60 as described above, if liquid such as water is spilled on the top surface of the upper mounting member 12, most of the liquid can be drained to the outside through the drainage holes 32 and the openings 33 below the upper mounting member 12. Furthermore, in the unlikely event that liquid such as water seeps into the space in which the speaker 70 is disposed through the speaker hole 31, the liquid can be drained from the openings 33 to the outside of the space in which the speaker 70 is disposed before the liquid reaches the sound generating portion 72.

[0050] In this embodiment, the drainage mechanism 60 has an inclined portion 73 and an opening 33 located below the sound generating portion 72 on the front side of the speaker 70. As a result, when water or the like is splashed on the refrigerator 1 from above, the water that has entered the inside of the cover member 22 from the speaker hole 31 can be guided toward the opening 33 located below the speaker 70. The liquid such as water guided toward the opening 33 is discharged from the opening 33 to the outside of the upper mounting member 12.

[0051] 7, the hollowed-out space 50 is located on the front side of the vertical wall 31a of the cover member 22, and has a shape that is hollowed out continuously downward from the vertical wall 31a. Therefore, there is no step around the outlet of the speaker hole 31 formed in the vertical wall 31a, and the front side of the speaker hole 31 is an open space. This reduces obstacles that block the sound emitted from the speaker hole 31, and allows the sound to be transmitted forward efficiently.

[0052] <Configuration of cover material> Next, a more detailed configuration of the cover member 22 will be described. In particular, the drain groove 23 formed on the upper surface of the cover member 22 and the structure around it will be described.

[0053] As shown in FIGS. 2 and 3, the upper surface of the cover member 22 is mainly formed by a front portion 22a, a rear portion 22b, and a groove portion 22c.

[0054] The front portion 22a constitutes the front side of the upper mounting member 12. A hinge reinforcing portion 81 is disposed below the front portion 22a.

[0055] The rear portion 22b constitutes the rear side of the upper mounting member 12. A speaker 70 is disposed below the rear portion 22b.

[0056] The groove portion 22c is located between the front portion 22a and the rear portion 22b. The front portion 22a and the rear portion 22b are formed to be flush with each other, and the groove portion 22c is formed at a position recessed one step downward from the front portion 22a and the rear portion 22b. A front inclined portion 22d is formed at the boundary between the front portion 22a and the groove portion 22c.

[0057] The drain groove 23 has a central portion extending in the left-right direction, and both left and right end portions extending diagonally rearward. A dug space 50 is formed in approximately the center of the drain groove 23 extending in the left-right direction.

[0058] The front surface of the hollowed out space 50 is defined by the front inclined portion 22d (see FIG. 7), and the rear surface of the hollowed out space 50 is defined by the vertical wall 31a (see FIG. 7).

[0059] Speaker hole 31 is formed in vertical wall 31a forming dug space 50. That is, speaker hole 31 is formed in the rear wall forming dug space 50. This makes it possible to achieve a configuration in which water is less likely to enter inside speaker hole 31 (i.e., the space in which speaker 70 is disposed) even if water or the like is splashed onto speaker hole 31 from above.

[0060] On the other hand, the front surface of the dug space 50 is a front inclined portion 22d. With this, when water splashes on the front portion 22a of the cover member 22, the water can be guided toward the dug space 50 along the gradient of the front inclined portion 22d. The water guided toward the dug space 50 passes through the drainage hole 32 and the opening 33 and is discharged below the upper mounting member 12.

[0061] A left inclined portion 37a and a right inclined portion 37b are formed around the periphery of the dug space 50. The left inclined portion 37a is located on the left side of the dug space 50 when viewed from the front, and is inclined downward toward the left side. The right inclined portion 37b is located on the right side of the dug space 50 when viewed from the front, and is inclined downward toward the right side.

[0062] In this way, the left inclined portion 37a and the right inclined portion 37b have a gradient that slopes downward from the dug space 50 toward the outside. As a result, the front of the vertical wall in which the speaker hole 31 is provided is the dug space 50, so that obstacles that block the sound of the speaker 70 can be reduced, and the sound of the speaker 70 can be made easier to hear. The left inclined portion 37a and the right inclined portion 37b can guide water away from the dug space 50 on the left and right sides of the dug space 50. Water that flows down into the groove portion 22c along the gradient of the left inclined portion 37a, etc., flows outward along the shape of the groove portion 22c, and is finally discharged to the outside from either the left or right end of the cover member 22. Therefore, the drainage hole 32 arranged at the bottom of the dug space 50 only needs to drain water that has fallen above the dug space 50, and the infiltration of water into the interior of the upper mounting member 12 can be suppressed.

[0063] As described above, the upper mounting member 12 is disposed on the upper surface of the insulating box 10 of the refrigerator 1 according to this embodiment. Inside the upper mounting member 12, the speaker 70, which is an example of an electronic component, is disposed.

[0064] The speaker 70 is configured to emit sound toward the side. That is, the sound generating unit 72 of the speaker 70 is disposed on the side of the main body of the speaker 70. In the refrigerator 1 equipped with the speaker 70, the speaker 70 emits sound toward the side, so that the user positioned on the refrigerator compartment door 11 side can more easily hear the sound of the speaker 70. In addition, since the sound generating unit 72 of the speaker 70 is disposed on the side, when water or the like is splashed on the refrigerator from above, the water is less likely to splash on the sound generating unit 72, compared to when the sound generating unit faces upward. Therefore, the durability of the speaker 70 can be improved.

[0065] In this embodiment, sound generating unit 72 of speaker 70 is provided on a side of the main body of speaker 70 that is located on the same side as the front of refrigerator 1 and upper mounting member 12. With this configuration, sound can be emitted toward the front of refrigerator 1.

[0066] Furthermore, the refrigerator 1 according to this embodiment is provided with a drainage mechanism 60 (specifically, drainage hole 32 and opening 33, etc.) as a mechanism for preventing liquid such as water from entering the speaker 70. Providing the drainage mechanism 60 prevents liquid such as water from entering the speaker 70 through a communication part that communicates with the outside, such as the speaker hole 31, and can improve the durability of the speaker 70.

[0067] Furthermore, in this embodiment, a drain groove 23 is provided as a configuration for draining liquid such as water that has splashed on the upper surface of the cover member 22. With this configuration, when water or the like splashes near the speaker hole 31, the water can be drained in a direction away from the speaker hole 31.

[0068] <Second embodiment> Next, a second embodiment of the present invention will be described. Fig. 10 and Fig. 11 show the configuration of upper mounting member 12 provided in refrigerator 1 according to the second embodiment. Fig. 11 is a diagram showing the cross-sectional configuration of line CC portion (i.e., the formation position of positioning protrusion 138 and positioning hole 139) of upper mounting member 12 shown in Fig. 10. Fig. 12 shows the configuration of base member 21 of upper mounting member 112.

[0069] The outer shape of the upper mounting member 12 is mainly composed of a base member 21 and a cover member 22. In the upper mounting member 12 according to this embodiment, a structure for positioning the base member 21 and the cover member 22 is provided at a position near the center of the upper mounting member 12 in the left-right direction.

[0070] Specifically, as shown in Figures 11 and 12, two positioning protrusions 138 are provided on base member 21 so as to protrude upward. Also, as shown in Figure 11, cover member 22 is provided with protrusions 140 protruding downward at positions corresponding to each of positioning protrusions 138. Protrusions 140 are provided with positioning holes 139 into which positioning protrusions 138 fit.

[0071] In the left-right direction, which is the longitudinal direction of the upper mounting member 12, the positions of the dug-out space 50 in the cover member 22 and the opening 33 in the base member 21 tend to be easily misaligned. Therefore, in this embodiment, positioning protrusions 138 are formed on the left and right sides of the opening 33 of the base member 21. In addition, the cover member 22 is provided with protrusions 140 that protrude downward from its underside. The protrusions 140 are provided with positioning holes 139 that open downward. The positioning protrusions 138 of the base member 21 fit into the positioning holes 139.

[0072] This allows for more accurate alignment of the base member 21 and the cover member 22 in the vicinity of the opening 33. By arranging the positioning protrusion 138 and the positioning hole 139 so as to avoid the drain groove 23, they can be sufficiently engaged with each other.

[0073] Moreover, it is preferable to dispose the positioning protrusion 138 between the opening 33 and the hinge portion 80. The vicinity of the hinge portion 80 is firmly fixed to the upper surface 10a of the insulating box 10, so that it can be set at a reference position, and disposing the positioning protrusion 138 between the two hinge portions 80 enables more accurate positioning.

[0074] Therefore, according to the configuration of this embodiment, it is possible to more accurately align the base member 21 and the cover member 22, and it is possible to more reliably ensure the gap G.
