[0020] Hereinafter, various embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components. Their names and functions are also the same. Therefore, detailed descriptions thereof will not be repeated.

[0021] [First embodiment]

[0022] In this embodiment, as a refrigerator of one aspect of the present invention, a refrigerator including a speaker on the upper surface of a refrigerator body is described as an example.

[0023] <Overall structure of refrigerator>

[0024] Figure 1The structure of the front side of the refrigerator 1 of this embodiment is shown. The outer shape of the main body of the refrigerator 1 is mainly formed by an insulated box body (refrigerator main body) 10. The refrigerator 1 has a first refrigerating chamber in the upper section, a second refrigerating chamber (vegetable chamber) in the middle section, and a freezing chamber in the lower section. In addition, the structure and configuration of each storage chamber in the refrigerator 1 are not limited to the above structure. The structure and configuration of each storage chamber can be appropriately changed according to the capacity and purpose of the refrigerator.

[0025] In addition, a refrigerator door 11 is provided in the first refrigerator room of the upper section. The refrigerator door 11 is a double-opening 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 door 11 are provided at the left and right ends of the refrigerator door 11. Specifically, the left grip 82a is provided at the left end of the refrigerator door 11. In addition, the right grip 82b is provided at the right end of the refrigerator door 11.

[0026] The second refrigerating chamber (vegetable chamber) in the middle stage is provided with a drawer-type refrigerating chamber door 13. A drawer-type freezing chamber door 14 is provided in the freezing chamber in the lower stage.

[0027] In addition, the structure of each door in the refrigerator 1 is not limited to the above-mentioned structure. The door of each storage room can be appropriately adopted, for example, a method of being able to open and close from both sides, a double-door method, a method of opening and closing from either end of the left and right, a method of being pulled out, etc., depending on the structure, purpose, location, etc. of each storage room.

[0028] In this embodiment, the surface provided with the door is referred to as the front (front) of the refrigerator. Moreover, with the front as a reference, the surfaces of the refrigerator 1 and the heat-insulating box 10 are referred to as the top, side, back (rear), and bottom according to the positions when the refrigerator 1 is set in a normal state. In addition, when the refrigerator 1 (or the heat-insulating box 10, the upper mounting member 12, etc.) is viewed from the front side, the side located on the left side is referred to as the left side of the refrigerator 1, etc., and the side located on the right side is referred to as the right side of the refrigerator 1, etc.

[0029] An upper mounting member 12 is disposed on the upper surface 10a of the heat insulating box 10. A speaker (electronic component) 70 and hinge reinforcement portions 81 (81a and 81b) are provided in the upper mounting member 12 (see Figure 5 ).

[0030] The speaker 70 can emit various notification sounds or voice messages to the user. In the present embodiment, the speaker 70 is configured to emit sound in the horizontal direction, that is, in the side direction (specifically, in the front direction). In the present embodiment, a speaker is listed as an example of an electronic component, but it is not limited to this, and a microphone may also be used. In addition, it may also be a sensor component that needs to detect the external air (such as a temperature, humidity sensor, human body sensor, etc.).

[0031] The hinge reinforcement part 81 is composed of a left hinge reinforcement part 81a constituting the left hinge part of the refrigerator 1 and a right hinge reinforcement part 81b constituting the right hinge part of the refrigerator 1. A hinge pin and the like are mounted on each hinge reinforcement part 81a and 81b to constitute a hinge part, and a metal plate-like member is included to improve the strength of the hinge part.

[0032] <Structure of upper mounting parts>

[0033] Next, the structure of the upper mounting member 12 will be described. Figure 2 , the appearance of the upper mounting member 12 is shown. Figure 3 The structure of the upper mounting member 12 is shown when viewed from above. Figure 2 and Figure 3 In FIG. 1 , the upper surface 10a of the heat-insulating box body 10 is also shown. Figure 4 2 shows the structure of the upper mounting member 12 when viewed from the front (front). Figure 5 as well as Figure 6 The internal structure of the upper mounting member 12 is shown. Figure 5 and Figure 6 This is a diagram showing a state in which the cover member 22 is removed from the upper mounting member 12 .

[0034] 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 by, for example, 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 configured to cover the upper portion of the base member 21.

[0035] The speaker 70 and the hinge reinforcement 81 (81a and 81b) are arranged inside the upper mounting member 12 whose outer shape is formed by the base member 21 and the cover member 22 (see Figure 5 ).

[0036] In another embodiment, instead of providing the base member 21 , the speaker 70 and the like may be directly provided on the upper surface of the heat insulating box 10 , and the cover member 22 may be provided so as to cover them.

[0037] The speaker 70 is disposed on the rear side of the upper mounting member 12. Specifically, the speaker 70 is disposed at a substantially central portion in the left-right direction of the rear side of the base member 21. By disposing the speaker 70 at a substantially central portion in the left-right direction of the rear side of the base member 21, the speaker 70 (specifically, the speaker hole 31) can output sound toward a person standing at the center of the front side of the refrigerator 1.

[0038] The speaker 70 is connected to a control board (not shown) on the refrigerator body side via a harness 71. The harness 71 is arranged 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 for connecting to the outside of the upper mounting member 12 at the left end of the base member 21 (see FIG. Figure 5 ).

[0039] The hinge reinforcement part 81 is arranged on the front side of the base member 21 and extends in the left-right direction. The hinge reinforcement part 81 is formed of a relatively high rigidity material such as metal. In the present embodiment, the hinge reinforcement part 81 is formed by processing a metal plate into a predetermined shape.

[0040] The hinge reinforcement portion 81 includes a left hinge reinforcement portion 81 a and a right hinge reinforcement portion 81 b .

[0041] The left hinge reinforcement portion 81a is arranged at the left hinge portion 80 (i.e., the left end portion of the front surface side of the upper mounting member 12). Specifically, the left hinge reinforcement portion 81a is arranged at the left corner portion of the front of the bottom surface of the base member 21, and the left hinge portion 80 is exposed downward through an opening provided on the bottom surface of the base member 21.

[0042] The right hinge reinforcement part 81b is arranged on the left hinge part 80 (i.e., the right end part of the front surface side of the upper mounting member 12). Specifically, the right hinge reinforcement part 81b is arranged at the right corner part of the front of the bottom surface of the base member 21, and the right hinge part 80 is exposed downward through the opening provided on the bottom surface of the base member 21.

[0043] <Speaker and its surrounding structure>

[0044] Next, a more detailed structure of speaker 70 and its periphery will be described. Figure 7 The structure around the speaker 70 inside the upper mounting member 12 is shown. Figure 7 It is shown Figure 4 FIG. 2 is a diagram showing a cross-sectional structure of the upper mounting member 12 taken along line AA (ie, a position where the drain hole 32 is formed).

[0045] like Figure 7As shown in FIG. 1 , a hollow space 50 formed by recessing the cover member 22 is provided in front of the speaker 70. A drainage mechanism 60 is provided in the hollow space 50 for preventing water or the like from entering the speaker 70. Figure 8 The structure around the undercut space 50 in which the drainage mechanism 60 is provided is shown. Figure 8 Yes means Figure 3 FIG. 2 is a diagram showing a cross-sectional structure of the upper mounting member 12 taken along line BB.

[0046] The speaker 70 has a sounding part 72. The sounding part 72 is disposed on one side of the main body of the speaker 70. In the present embodiment, the sounding part 72 is provided on the side of the main body of the speaker 70 on the same side as the front of the refrigerator 1 and the upper mounting member 12.

[0047] By arranging the sound emitting part 72 on one side of the main body of the speaker 70, the sound emitting part 72 can emit sound to the side. Here, the side refers to the horizontal direction when the refrigerator 1 is arranged on a horizontal plane. In addition, here, the side is defined as a direction including the front direction, the rear direction, the right direction, the left direction, and at least one direction of the inclined direction between these directions.

[0048] As in the present embodiment, by providing the sound generating portion 72 on the side surface of the front side of the main body of the speaker 70, Figure 7 As indicated by arrow P in FIG. 1 , the speaker 70 can emit sound from the front side of the refrigerator 1 toward the front side.

[0049] like Figure 7 As shown, the upper part of the speaker 70 is covered by the cover member 22. In addition, a vertical wall 31a as a part of the cover member 22 is provided on the front side of the sound-emitting portion 72. On the vertical wall 31a, a speaker hole 31 is formed at a position corresponding to the sound-emitting portion 72 (an area overlapping the sound-emitting portion 72 when viewed from the front). The speaker hole 31 is composed of a plurality of small holes. The speaker hole 31 is an example of a connecting portion.

[0050] 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 slope that is inclined downward from the sound-generating portion 72 side toward the speaker hole 31 side (see Figure 7 ).

[0051] The guide portions 74 are provided on both sides of the inclined portion 73. That is, the guide portions 74 are arranged at positions opposite to each other with the inclined portion 73 sandwiched therebetween. The guide portions 74 are formed to be higher than the inclined surface of the inclined portion 73. Figure 6As shown, guide portions 74 and side walls 74 are formed on the left and right sides of the inclined portion 73. This configuration can prevent the sound emitted from the sound emitting portion 72 of the speaker 70 from diffusing to the left and right sides. Therefore, the sound emitted from the sound emitting portion 72 can be efficiently guided to the speaker hole 31.

[0052] A drainage mechanism 60 is provided on the front side of the speaker 70 (i.e., the side where the speaker hole 31 is located relative to the speaker 70). The drainage mechanism 60 is a mechanism for quickly discharging liquid such as water to the upper surface 10a of the heat-insulating box 10 below the base member 21 when liquid is applied to the upper surface of the cover member 22, and for preventing the liquid from entering the interior of the upper mounting member 12. Thus, it is possible to prevent the liquid from reaching the speaker 70.

[0053] The drain mechanism 60 has a drain hole 32 and an opening 33. The drain hole 32 is formed in the cover member 22. The opening 33 is formed in the base member 21. The drain hole 32 and the opening 33 are arranged at positions where they at least partially overlap in a plan view.

[0054] The drainage hole 32 is formed on the bottom surface of the hollow space 50 formed by recessing a portion of the cover member 22. Figure 3 As shown, in the present embodiment, the drain hole 32 is composed of two holes arranged side by side, but the structure of the drain hole 32 is not limited to this.

[0055] The opening 33 is disposed in front of the speaker 70. Figure 5 As shown, in this embodiment, the opening portion 33 has a substantially rectangular opening in a plan view. The opening region of the drain hole 32 is arranged so as to be within the range of the opening region of the opening portion 33 in a plan view.

[0056] A surrounding wall 35 is formed on the upper surface 21a of the base member 21 (the surface on the inner side of the upper mounting member 12) so as to surround the periphery of the opening 33 (see Figure 5 as well as Figure 6 By providing such a surrounding wall 35 , even if a part of the liquid that passes through the drain hole 32 and the opening 33 enters the interior of the upper mounting member 12 , the liquid can be prevented from intruding into the interior of the surrounding wall 35 .

[0057] Therefore, it is possible to prevent components and wiring (for example, the wire harness 71 ) disposed inside the surrounding wall 35 from being wetted by water.

[0058] like Figure 7 , Figure 8As shown, the hollow space 50 is formed so that the drain hole 32 is located at a position overlapping the opening 33 in the vertical direction. Thus, the height difference between the speaker 70 and the speaker hole 31 and the drain hole 32 can be greatly ensured, and water intrusion from the speaker hole 31 can be suppressed.

[0059] A gap G is provided between the lower surface 22f (the surface on the inner side of the upper mounting member 12) around the drainage hole 32 of the cover member 22 and the upper surface 21a (the surface on the inner side of the upper mounting member 12) of the base member 21 (see Figure 8 ) That is, the opening 33 of the base member 21 is not blocked by the lower surface 22 f of the cover member 22 .

[0060] The water passing through the drainage hole 32 is discharged to the surrounding of the upper mounting member 12 through the space between the lower surface of the base member 21 and the upper surface 10a of the heat-insulating box 10. However, when the upper mounting member 12 is to be lowered, it is sometimes difficult to provide a sufficient height in the space between the lower surface of the base member 21 and the upper surface 10a of the heat-insulating box 10. In this case, the space between the lower surface of the base member 21 and the upper surface 10a of the heat-insulating box 10 is blocked by the surface tension of the water immersed in the space, and the air in the space is difficult to be discharged, so there is a problem that the water in the space is difficult to move.

[0061] In the present embodiment, in order to solve this problem, by ensuring the above-mentioned gap G, an area that connects the space between the lower surface of the base member 21 and the upper surface 10a of the heat-insulating box 10 and the upper mounting member 12 is ensured around the drain hole 32, so that 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, so that the water in the space can be easily moved. In addition, since the gap G is formed outside the hollow space 50, even if water accumulates in the hollow space 50, the gap G will not be blocked. As a result, it is possible to prevent the liquid that has penetrated into the interior of the upper mounting member 12 from the drain hole 32, the speaker hole 31, etc. from being continuously accumulated inside without being discharged.

[0062] In addition, if Fig. 9 As shown, a protrusion 34 may be provided on the lower surface 22f around the drain hole 32 in the cover member 22. The protrusions 34 are provided, for example, on the left and right sides of the drain hole 32. By providing such protrusions 34, even when the cover member 22 is pressed from above, the drain hole 32 can be prevented from contacting and being blocked by the upper surface 10a of the heat insulating box body 10. In addition, it is preferable to ensure the gap G even when the protrusion 34 is in contact with the upper surface 10a.

[0063] The upper mounting member 12 includes the drainage mechanism 60 as described above, so that when liquid such as water is sprinkled on the upper surface of the upper mounting member 12, most of the liquid can be discharged to the outside through the drainage hole 32 and the opening 33 through the bottom of the upper mounting member 12. In addition, if liquid such as water penetrates into the space where the speaker 70 is arranged from the speaker hole 31, the penetrated liquid can be discharged from the opening 33 to the outside of the space where the speaker 70 is arranged before reaching the sound-emitting portion 72.

[0064] In the present embodiment, the drainage mechanism 60 has an inclined portion 73 and an opening portion 33 located below the sound-generating portion 72 on the front side of the speaker 70. Thus, when water or the like is applied from above the refrigerator 1, the water that has entered the inside of the cover member 22 from the speaker hole 31 can be guided to the opening portion 33 located below the speaker 70. The liquid such as water guided to the opening portion 33 is discharged from the opening portion 33 to the outside of the upper mounting member 12.

[0065] In addition, if Figure 7 As shown in the figure, the hollowed-out space 50 is located on the front side of the vertical wall 31a of the cover member 22, and is in a shape that is continuously recessed downward from the vertical wall 31a. Therefore, there is no step difference around the outlet of the speaker hole 31 formed in the vertical wall 31a, and the front side of the speaker hole 31 is open. As a result, obstacles that block the sound emitted from the speaker hole 31 can be reduced, and the sound can be effectively transmitted to the front.

[0066] <Structure of Cover Member>

[0067] Next, a more detailed structure of the cover member 22 will be described. Here, in particular, the drain groove 23 formed on the upper surface of the cover member 22 and the structure of its surroundings will be described.

[0068] like Figure 2 and Figure 3 As shown, 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.

[0069] The front portion 22a constitutes the front side of the upper mounting member 12. A hinge reinforcement portion 81 is disposed below the front portion 22a.

[0070] The rear portion 22b constitutes the rear side of the upper mounting member 12. A speaker 70 is disposed below the rear portion 22b.

[0071] The groove 22c is located between the front portion 22a and the rear portion 22b. The front portion 22a and the rear portion 22b are formed flush, and the groove 22c is formed at a position that is 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 22c.

[0072] The center portion of the drain groove 23 extends in the left-right direction, and the left and right end portions thereof extend obliquely rearward. A hollowed-out space 50 is formed substantially in the center of the drain groove 23 extending in the left-right direction.

[0073] The front side surface of the hollow space 50 is formed by the front inclined portion 22d (see Figure 7 The rear side of the hollow space 50 is formed by the vertical wall 31a (see Figure 7 ).

[0074] The speaker hole 31 is formed in the vertical wall 31a forming the hollowed-down space 50. That is, the speaker hole 31 is formed in the wall on the rear side forming the hollowed-down space 50. Thus, even when water or the like is applied from above the speaker hole 31, it is possible to form a structure in which water is difficult to penetrate into the inside of the speaker hole 31 (that is, the space where the speaker 70 is arranged).

[0075] On the other hand, the surface on the front side of the hollowed-down space 50 is the front inclined portion 22d. Thus, when water is applied to the front portion 22a of the cover member 22, the water can be guided to the hollowed-down space 50 along the slope of the front inclined portion 22d. The water guided to the hollowed-down space 50 is discharged to the bottom of the upper mounting member 12 through the drainage hole 32 and the opening 33.

[0076] A left inclined portion 37a and a right inclined portion 37b are formed around the lower excavated space 50. The left inclined portion 37a is located on the left side of the lower excavated 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 lower excavated space 50 when viewed from the front, and is inclined downward toward the right side.

[0077] Thus, the left inclined portion 37a and the right inclined portion 37b have a slope that is inclined downward from the hollowed space 50 toward the outside. Thus, since the front of the vertical wall where the speaker hole 31 is provided becomes the hollowed space 50, it is possible to reduce obstacles that block the sound of the speaker 70, and the sound of the speaker 70 can be heard more easily. In addition, the left and right sides of the hollowed space 50 can guide water in a direction away from the hollowed space 50 through the left inclined portion 37a and the right inclined portion 37b. The water that flows down the groove 22c along the slope of the left inclined portion 37a and the like flows outward along the shape of the groove 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 disposed at the bottom of the hollowed space 50 only needs to discharge the water poured on the hollowed space 50, and it is possible to suppress the intrusion of water into the interior of the upper mounting member 12.

[0078] As described above, in the heat insulating box 10 of the refrigerator 1 according to the present embodiment, the upper mounting member 12 is disposed on the upper surface thereof. Inside the upper mounting member 12, the speaker 70 and the like as an example of electronic components are disposed.

[0079] The speaker 70 is configured to emit sound to the side. That is, the sound-emitting portion 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 to the side, so that the user located on the side of the refrigerator door 11 can more easily hear the sound of the speaker 70. In addition, by arranging the sound-emitting portion 72 of the speaker 70 to the side, when water is applied from above the refrigerator, it is difficult for the water to contact the sound-emitting portion 72, compared with the case where the sound-emitting portion faces upward. Therefore, the durability of the speaker 70 can be improved.

[0080] In this embodiment, the sound emitting part 72 of the speaker 70 is provided on the side of the main body of the speaker 70 located on the same side as the front of the refrigerator 1 and the upper mounting member 12. According to this structure, the sound can be emitted toward the front of the refrigerator 1.

[0081] In addition, in the refrigerator 1 involved in this embodiment, a drainage mechanism 60 (specifically, the drainage hole 32 and the opening 33, etc.) is provided as a mechanism for preventing liquid such as water from penetrating into the speaker 70. By providing the drainage mechanism 60, it is possible to suppress liquid such as water from penetrating into the speaker 70 through the connecting portion connected to the outside such as the speaker hole 31, and the durability of the speaker 70 can be improved.

[0082] In this embodiment, drainage groove 23 is provided as a structure for draining liquid such as water applied to the upper surface of cover member 22. With this structure, when water is applied near speaker hole 31, the water can be drained away from speaker hole 31.

[0083] <Second Embodiment>

[0084] Next, a second embodiment of the present invention will be described. Fig.10 and Fig.11 2 shows the structure of the upper mounting member 12 included in the refrigerator 1 according to the second embodiment. Fig.11 Yes means Fig.10 FIG. 2 is a diagram showing a cross-sectional structure of the CC line portion of the upper mounting member 12 (ie, the formation position of the positioning protrusion 138 and the positioning hole 139 ). Fig.12 The structure of the base member 21 of the upper mounting member 112 is shown.

[0085] The outer shape of the upper mounting member 12 is mainly composed of the base member 21 and the cover member 22. In the upper mounting member 12 of this embodiment, a structure for positioning the base member 21 and the cover member 22 is provided near the center of the upper mounting member 12 in the left-right direction.

[0086] Specifically, if Fig.11 and Fig.12 As shown in FIG. 1 , two positioning protrusions 138, 138 are provided on the base member 21 in a manner protruding upward. Fig.11 As shown in FIG. 1 , the cover member 22 is provided with protrusions 140, 140 protruding downward at positions corresponding to the positioning protrusions 138, 138. The protrusions 140 are provided with positioning holes 139 into which the positioning protrusions 138 are inserted.

[0087] The left-right direction, which is the longitudinal direction of the upper mounting member 12, has a tendency that the positions of the hollowed-out space 50 in the cover member 22 and the opening 33 in the base member 21 are easily offset. Therefore, in the present embodiment, positioning protrusions 138, 138 are formed in front of 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, 140 protruding downward from the lower surface thereof. The protrusion 140 is provided with a positioning hole 139 opening downward. The positioning protrusion 138 of the base member 21 is fitted into the positioning hole 139.

[0088] This allows more accurate positioning of the base member 21 and the cover member 22 near the opening 33. Furthermore, by arranging the positioning protrusions 138 and the positioning holes 139 so as to avoid the drain grooves 23, they can be sufficiently engaged with each other.

[0089] The positioning protrusion 138 is preferably disposed between the opening 33 and the hinge 80. Since the vicinity of the hinge 80 is firmly fixed to the upper surface 10a of the heat insulating box 10, it can be set at a reference position, and by disposing the positioning protrusion 138 between the two hinges 80, more accurate positioning can be performed.

[0090] Therefore, according to the structure of this embodiment, the base member 21 and the cover member 22 can be more accurately positioned, and the gap G can be ensured more reliably.

[0091] When the cover member 22 is positioned relative to the base member 21 as in the present embodiment, the left and right ends of the cover member 22 are preferably arranged to cover the left and right ends of the base member 21 with a slight gap therebetween.
