Description

Technical Field

[0001] The present invention relates to a cooler box. Background Art

[0002] Generally, a structure for ensuring airtightness is provided in a refrigerator. For example, the refrigerator in Patent Document 1 has a refrigerator body, a cover member, a step portion, and a sealing member. The refrigerator body has a bottom and a wall portion. The wall portion extends upward from the bottom. The top end of the wall portion forms an opening. The cover member is mounted on the refrigerator body in a swingable manner and covers the opening of the refrigerator body. The step portion is provided at the opening of the refrigerator body. The sealing member is mounted on the cover member. The sealing member is arranged on the step portion. The outer surface of the sealing member contacts both the bottom surface of the step portion and the peripheral wall surface of the step portion. [Prior art literature] [Patent Document]

[0003] Patent Document 1: Japanese Patent Publication No. 9-255053 Summary of the invention [Technical problem to be solved by the invention]

[0004] In the refrigerator of Patent Document 1, the outer peripheral surface of the sealing member is pressed against the peripheral wall surface of the step portion in a state where the cover member covers the opening of the box body and the lower surface of the sealing member presses the bottom surface of the step portion. That is, in the refrigerator of the prior art, the sealing member is fitted with the step portion in a state where the deformation of the sealing member is restricted.

[0005] Here, when an external force such as tilt or vibration of the refrigerator acts on the refrigerator, the liquid (melted ice water, seawater) in the refrigerator may collide with the inner surface of the cover member. In this case, since the water pressure acts locally unevenly (biased) on the sealing member, there is a risk of reduced waterproofness.

[0006] An object of the present invention is to provide a refrigerator capable of maintaining waterproofness between a refrigerator body and a lid member. [Technical solutions for solving technical problems]

[0007] Regarding the first technical solution of the present invention, the cold storage box has a box body, a cover part, a first inclined surface and a sealing part. The box body has a bottom, a wall, a storage space and an opening. The bottom is arranged on a horizontal plane. The wall extends upward from the bottom. The storage space is formed by the bottom and the wall. The opening is arranged at the top end of the wall.

[0008] The cover member is used to cover the opening. The first inclined surface is provided on either the opening or the cover member. The first inclined surface is inclined from the receiving space side to the outside in the direction from the bottom to the top. The sealing member is arranged on the other of the opening and the cover member in a manner opposite to the first inclined surface. The sealing member contacts within the surface of the first inclined surface.

[0009] In the refrigerator of the first aspect of the present invention, the first inclined surface is provided on one of the opening and the cover member, and the sealing member is provided on the other of the opening and the cover member. In this state, the sealing member is in contact with the first inclined surface.

[0010] In this case, when an external force such as tilt or vibration of the refrigerator acts on the refrigerator, the cover member moves relative to the refrigerator body due to the play generated between the refrigerator body and the cover member. At this time, the sealing member deforms on the first inclined surface while in contact with the first inclined surface, thereby increasing the compression rate of the sealing member.

[0011] Thus, compared with the prior art, the present refrigerator can maintain the waterproofness between the refrigerator body and the cover member. Specifically, even if the water pressure acts on the sealing member between the refrigerator body and the cover member more eccentrically, the present refrigerator can maintain the waterproofness. In addition, in the refrigerator of Patent Document 1, since the sealing member is engaged with the step portion in a state where the deformation of the sealing member is restricted, the cover member does not move relative to the refrigerator body.

[0012] Regarding the second technical solution of the present invention, the refrigerator according to the first technical solution may be configured as follows: The cover member has a protrusion disposed opposite to the first inclined surface. The protrusion includes a second inclined surface extending in a direction intersecting the first inclined surface.

[0013] In the refrigerator of the second technical solution of the present invention, the cover member has a protrusion, and the protrusion includes a second inclined surface. In this structure, when an external force such as tilt or vibration of the refrigerator acts on the refrigerator, the liquid contained in the refrigerator presses the second inclined surface of the cover member. Accordingly, the sealing member deforms on the first inclined surface while in contact with the first inclined surface, so that the compression rate of the sealing member increases. That is, the waterproofness between the box body and the cover member can be maintained.

[0014] Regarding the third aspect of the present invention, the refrigerator according to the second aspect may be configured as follows: The sealing member is disposed between the first inclined surface and the second inclined surface in the horizontal direction.

[0015] In the refrigerator according to the third aspect of the present invention, when an external force such as the refrigerator tilting or vibration acts on the refrigerator, the sealing member can be appropriately deformed along the first inclined surface.

[0016] Regarding a fourth aspect of the present invention, the refrigerator according to any one of the first to third aspects may be configured as follows: The opening portion includes a standing portion disposed at a distance from the cover member in the horizontal direction.

[0017] In the refrigerator of the fourth aspect of the present invention, the movement of the cover member relative to the refrigerator body is restricted by the upright portion. This can restrict the cover member from moving too much relative to the refrigerator body. [Effects of the invention]

[0018] In the present invention, in the refrigerator, the waterproof property between the box body and the lid member can be maintained. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] like Figure 1 As shown, a refrigerator 1 according to an embodiment of the present invention comprises a refrigerator body 3, a lid member 5, a pair of opening and closing structures 7, 8 and a sealing member 9 (see Figure 2 The box body 3 is formed into a rectangular box shape. The box body 3 is made of resin, for example. It is preferred that a heat insulating material is enclosed in the box body 3.

[0021] like Figure 2 and Figure 3 As shown, the box body 3 has a bottom 11, a wall 13, a storage space S and an opening 15. In this embodiment, the bottom 11 is formed in a rectangular shape. The bottom 11 can also be in other shapes. Figure 4 As shown, the bottom 11 is arranged on a horizontal plane H. The horizontal plane H is a plane perpendicular to the direction in which gravity acts. The horizontal plane H includes the ground on which the refrigerator 1 can be arranged and the mounting surface of a vehicle on which the refrigerator 1 can be mounted.

[0022] like Figure 1 to Figure 4 As shown in FIG. 1 , the wall portion 13 is integrally formed on the outer periphery of the bottom portion 11. The wall portion 13 extends upward from the bottom portion 11. Specifically, as shown in FIG. Figure 4 As shown, when the bottom 11 is arranged on the horizontal plane H, Figure 1 , Figure 2 and Figure 3 As shown in FIG. 1 , the wall portion 13 surrounds the outer periphery of the bottom portion 11 and extends upward from the outer periphery of the bottom portion 11. Figure 2 and Figure 3 As shown, the storage space S is formed by a bottom portion 11 and a wall portion 13. The storage space S stores items, ice for cooling the temperature in the storage space S, and seawater for maintaining freshness when the items are fish.

[0023] like Figure 2 to Figure 4 As shown in FIG. 1 , the opening 15 is disposed at the top end of the wall 13, for example, at the upper end of the wall 13. Figure 5 and Figure 6 As shown, when the refrigerator 1 is viewed from above, the opening 15 is formed in a rectangular shape.

[0024] like Figure 3 to Figure 6 As shown in FIG. 1 , the opening 15 includes a vertical portion 19 and a rectangular main body 17. The main body 17 is formed in a rectangular shape. The main body 17 is formed integrally with the wall 13 at the upper end of the wall 13. Figure 3 , Figure 5 and Figure 6 As shown in FIG. 1 , the main body 17 is provided with a first inclined surface 17 a .

[0025] like Figure 7 and Figure 8As shown, the first inclined surface 17a is inclined outward from the storage space S in the direction from the bottom 11 toward the top. In other words, the first inclined surface 17a is inclined so as to be away from the bottom 11 as it moves from the inner surface 13a of the wall 13 to the outer surface 13b of the wall 13.

[0026] like Figure 3 and Figure 4 As shown in FIG. 1 , the upright portion 19 is disposed on the main body 17. Specifically, as Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the upright portion 19 includes a pair of upright portions 19a and 19b. The pair of upright portions 19a and 19b extend upward from the main body 17. The pair of upright portions 19a and 19b are connected to the respective shaft portions 7a and 8a of the pair of opening and closing structures 7 and 8 (see Fig. 9 ) are arranged on the main body 17 in a manner opposite to each other in the axial direction extending.

[0027] In this embodiment, if Fig. 9 As shown, the axial direction and the orthogonal direction are defined. When the bottom 11 is arranged on the horizontal plane H, the axial direction and the orthogonal direction are defined on the horizontal plane H or on a plane parallel to the horizontal plane H, wherein the axial direction is the direction in which the shaft portions 7a, 8a of the pair of opening and closing structures 7, 8 extend; and the orthogonal direction is the direction orthogonal to the axial direction in which the shaft portions 7a, 8a of the pair of opening and closing structures 7, 8 extend.

[0028] When the bottom portion 11 is disposed on the horizontal plane H, the direction from one of the pair of upright portions 19a and 19b to the other of the pair of upright portions 19a and 19b on the horizontal plane H or on a plane parallel to the horizontal plane H may be interpreted as the axial direction.

[0029] In addition, when the bottom 11 is arranged on the horizontal plane H, the direction orthogonal to the direction from one of the pair of upright portions 19a and 19b to the other of the pair of upright portions 19a and 19b on the horizontal plane H or on a plane parallel to the horizontal plane H can be interpreted as the above-mentioned orthogonal direction.

[0030] like Fig. 9As shown, a pair of upright portions 19a, 19b are arranged on both sides of the cover member 5 in the axial direction. The pair of upright portions 19a, 19b are arranged at intervals from the cover member 5 in the axial direction. That is, a gap G1 is provided between each of the pair of upright portions 19a, 19b and the outer edge portion 5a of the cover member 5. The cover member 5 moves between the pair of upright portions 19a, 19b within the range of the gap G1. In this embodiment, a gap G1 is generated in the axial direction between the box body 3 and the cover member 5, and a gap not shown in the figure is generated between the shaft portion 7a, 8a and the cover member 5, and these gaps become the clearances possessed by the opening and closing mechanisms 7, 8.

[0031] like Figure 1 , Figure 7 to Figure 9 As shown, the cover member 5 is formed separately from the box body 3. Figure 1 and Fig. 9 As shown, the cover member 5 is detachable relative to the box body 3 through a pair of opening and closing structures 7 and 8. Figure 7 and Figure 8 As shown, when the cover member 5 is mounted on the box body 3, the cover member 5 covers the opening 15 of the box body 3. In this state, the cover member 5 is arranged at a distance from the first inclined surface 17a of the box body 3. Figure 7 As shown, a gap G2 between the cover member 5 and the first inclined surface 17 a of the box body 3 is sealed by the sealing member 9 .

[0032] like Figure 7 and Figure 8 As shown, the cover member 5 includes a cover body 21, a protrusion 23, and a groove 25. The cover body 21 is disposed to face the bottom 11 of the box body 3. In the present embodiment, the cover body 21 is formed in a rectangular shape.

[0033] The protrusion 23 protrudes from the inner surface of the cover body 21. Specifically, the protrusion 23 protrudes from the inner surface of the cover body 21 along the outer edge 5a of the cover body 21. When the cover member 5 is mounted on the box body 3, the protrusion 23 is arranged opposite to the first inclined surface 17a. The top end of the protrusion 23 is arranged at a distance G2 from the first inclined surface 17a.

[0034] like Fig.10 As shown, the protrusion 23 includes an outer side surface 23a and a second inclined surface 23b. The outer side surface 23a forms the outer side surface of the protrusion 23 and the inner side surface of the groove portion 25. The second inclined surface 23b forms the inner side surface of the protrusion 23. The second inclined surface 23b is connected to the inner surface 21a of the cover body 21. When the cover member 5 is mounted on the box body 3, the second inclined surface 23b extends in a direction intersecting with the first inclined surface 17a. In the present embodiment, the second inclined surface 23b extends in a manner substantially orthogonal to the first inclined surface 17a.

[0035] like Figure 7 and Figure 8 As shown in FIG. 2 , the sealing member 9 is disposed in the groove portion 25. The groove portion 25 is provided on the inner surface 21a side of the cover body 21 so as to be adjacent to the protrusion 23. Fig.10 As shown, the groove portion 25 has a bottom surface 25a and a pair of wall surfaces 23a and 25b. The bottom surface 25a is formed on the cover body 21 so as to surround the protrusion 23. The bottom surface 25a extends outward from the outer side surface 23a of the protrusion 23. The wall surface 23a is formed by the outer side surface 23a of the protrusion 23. The wall surface 25b is arranged at a distance from the wall surface 23a and extends downward from the bottom surface 25a.

[0036] like Fig. 9 As shown, a pair of opening and closing structures 7 and 8 are installed on the cover member 5. The pair of opening and closing structures 7 and 8 have shaft portions 7a and 8a, operating handles 7b and 8b, and engaging portions 7c and 8c, wherein the shaft portions 7a and 8a rotate relative to the cover member 5, respectively; the operating handles 7b and 8b rotate integrally with the shaft portions 7a and 8a, respectively; and the engaging portions 7c and 8c engage with a pair of upright portions 19a and 19b of the box body 3, respectively.

[0037] When the cover member 5 is mounted on the box body 3, by pulling up one of the operating handles 7b and 8b of the pair of opening and closing structures 7 and 8, one of the shafts 7a and 8a of the pair of opening and closing structures 7 and 8 is rotated, the engagement between the engaging portions 7c and 8c of the pair of opening and closing structures 7 and 8 and one of the pair of upright portions 19a and 19b of the box body 3 is released. Accordingly, the cover member 5 can be rotated relative to the box body 3 around the other of the shafts 7a and 8a of the pair of opening and closing structures 7 and 8, so that the storage space S is opened.

[0038] When the cover member 5 is arranged on the box body 3, by pressing the operating handles 7b, 8b of the pair of opening and closing structures 7, 8, the shaft portions 7a, 8a of the pair of opening and closing structures 7, 8 are rotated, and the engaging portions 7c, 8c of the pair of opening and closing structures 7, 8 are engaged with the wall portion 13 of the box body 3. Accordingly, the cover member 5 is mounted on the box body 3.

[0039] like Figure 7 and Figure 8 As shown, the sealing member 9 is arranged on the cover member 5 so as to face the first inclined surface 17a. The sealing member 9 is in contact with the first inclined surface 17a. The sealing member 9 is formed of an elastically deformable material. Preferably, the sealing member 9 is formed of a material such as rubber or a thermoplastic elastomer.

[0040] Specifically, if Figure 7 , Figure 8 and Fig.10 As shown, the sealing member 9 is arranged in the groove portion 25. Fig.10As shown, the sealing member 9 has a fitting portion 9a and a contact portion 9b. The fitting portion 9a is a portion that fits into the groove portion 25. When the cover member 5 is mounted on the box body 3, at least a portion of the fitting portion 9a is horizontally disposed between the first inclined surface 17a and the second inclined surface 23b.

[0041] Here, the horizontal direction is defined on a plane parallel to the bottom 11. When the bottom 11 is arranged on the horizontal plane H, the horizontal direction is defined on the horizontal plane H or on a plane parallel to the horizontal plane H. In the present embodiment, the horizontal direction includes the axial direction and the orthogonal direction.

[0042] The contact portion 9b is formed integrally with the fitting portion 9a. When the fitting portion 9a is fitted in the groove portion 25, the contact portion 9b is arranged outside the groove portion 25. When the cover member 5 is attached to the box body 3, the contact portion 9b contacts the first inclined surface 17a.

[0043] In the refrigerator 1 having the above structure, when the lid 5 is attached to the refrigerator body 3, the lid 5 is arranged at a gap G2 from the first inclined surface 17a of the refrigerator body 3. The gap G2 between the lid 5 and the first inclined surface 17a of the refrigerator body 3 is sealed by the sealing member 9.

[0044] When the cover member 5 is mounted on the box body 3, for example Fig.10 The state is a state in which the cover member 5 can move relative to the box body 3 within the range of the clearance between the pair of opening and closing structures 7 and 8. In this state, when the cover member 5 moves in the orthogonal direction relative to the box body 3, for example, when the refrigerator box 1 is tilted or the second inclined surface 23b is moved in the direction opposite to the box body 3 by water pressure, etc. Fig.11 When the cover 5 moves in the first direction D1 of the middle arrow, the contact portion 9b of the sealing member 9 is deformed on the first inclined surface 17a while in contact with the first inclined surface 17a. As a result, the compression rate of the sealing member 9 increases. In this way, in the cold storage box 1, when the cover member 5 moves relative to the box body 3, the waterproofness between the box body 3 and the cover member 5 can be maintained.

[0045] When the cover member 5 moves axially relative to the box body 3, as shown in FIG. Fig.11 As shown in FIG. 1 , the contact portion 9b of the sealing member 9 is also deformed in the state of being in contact with the first inclined surface 17a, and the compression rate of the sealing member 9 increases. In this case, the waterproofness between the box body 3 and the cover member 5 can be maintained. In addition, by making the outer edge portion 5a of the cover member 5 Figure 8 The upright portion 19 in the cover 5 abuts against the cover 5, thereby restricting the cover 5 from moving relative to the box body 3. According to this, the cover 5 can be restricted from moving relative to the box body 3.

[0046] In the refrigerator 1 having the above structure, when the cover member 5 is attached to the refrigerator body 3, if an external force such as tilt or vibration of the refrigerator 1 acts on the refrigerator 1, the second inclined surface 23b of the cover member 5 is pressed in the direction D2 by the contents of the refrigerator 1. In this case, the cover member 5 is tilted relative to the refrigerator body 3. Fig.11 The compression rate of the sealing member 9 increases by moving the sealing member 9 in the second direction D1. Thus, the waterproof property between the box body 3 and the cover member 5 can be maintained.

[0047] <Modification> In the above embodiment, an example is shown in which the first inclined surface 17a is provided on the main body 17 of the opening 15 and the sealing member 9 is provided on the cover member 5. Fig.12 As shown, the first inclined surface 23c may be provided on the cover member 5, and the sealing member 119 may be provided on the main body 17 of the opening 15. In this case, the first inclined surface 23c is provided on the inner surface 21a side of the cover member 5. The first inclined surface 23c is adjacent to the second inclined surface 23b and is provided at a position closer to the outside than the second inclined surface 23b. The groove 125 is formed in the main body 17 of the opening 15, and the sealing member 119 is arranged in the groove 125. Even in this configuration, the same effect as the above-mentioned embodiment can be obtained.
