Description

freezer

The present invention relates to a refrigerator for storing and keeping fish and the like cold.

A refrigerator is known in the prior art, which has: a box-shaped main body and a cover that can be opened and closed on the upper part of the main body (refer to patent document 1). In the refrigerator, a through hole for drainage is provided at the lower part of the side wall of the main body, and a cylinder is inserted into the through hole. In addition, a male threaded portion is formed on the cylinder. The cylinder is fixed to the box body using a nut having a female threaded portion, and the above-mentioned female threaded portion can be screwed with the male threaded portion of the cylinder. Specifically, when the cylinder is inserted into the through hole of the main body, the nut tightens the cylinder from the inner side of the main body, thereby fixing the cylinder to the lower part of the side wall of the main body.

In the refrigerator, a bolt member can be installed at the end of the outer side of the cylinder. In addition, when the refrigerator is used to store fish or ice, the bolt member is installed on the cylinder to make the refrigerator sealed. And, when cleaning the refrigerator, for example, the bolt member can be removed from the cylinder to drain water from the inside of the main body through the cylinder.

[The problem the invention is trying to solve]

In such a refrigerator, when the cylinder is fixed to the box, as described above, since the nut for tightening the cylinder is arranged inside the main body, it is necessary to provide a space below the through hole at the lower part of the side wall of the main body for arranging tools such as a wrench used when tightening the nut, and accordingly, the cylinder is arranged at the upper part. As a result, when cleaning the refrigerator, for example, water may accumulate in the above space, and the refrigerator must be tilted for drainage, making it difficult to drain.

Therefore, the subject of the present invention is to provide a refrigerator that is easy to drain. [Technical means for solving the problem]

The refrigerator of the present invention comprises: a box-shaped main body, a cover and a cylinder, wherein the box-shaped main body has a through hole for drainage at the lower part of the side wall; the cover is openably arranged on the upper part of the main body; the cylinder is arranged on the through hole, and the cylinder has an adjacent part and a water guide part; the adjacent part is adjacent to the inner bottom surface of the main body in a state where the lowest part of the inner circumference of the cylinder is located at the same height as the inner bottom surface of the main body, or is adjacent to the inner bottom surface of the main body in a state where the lowest part of the inner circumference of the cylinder is located at a position lower than the inner bottom surface of the main body; the water guide part has a downwardly inclined part on the outer side of the adjacent part toward the outside.

According to this structure, since the adjacent portion of the inner circumferential surface of the cylinder is at the same height as the inner bottom surface of the main body, or is located below the inner bottom surface of the main body, the water contained and stored in the main body can be easily guided to the outside from the inner bottom surface of the main body through the adjacent portion of the inner circumferential surface of the cylinder and the water guide portion, and therefore it is easy to drain water from the main body.

In the refrigerator, the cylindrical body has a threaded portion on an outer peripheral surface, and thread teeth into which the threaded portion is screwed are formed on an inner surface of the through hole.

According to this structure, since the cylinder is installed on the lower part of the side wall by screwing, the cylinder is not easy to fall off from the lower part of the side wall.

In this case, in the refrigerator, the main body has a cylindrical covering portion extending radially inwardly of the thread teeth at the inner end portion.

According to this structure, since the cylinder is covered by the cylinder cover, the threaded portion and the thread teeth are not exposed to the inner side of the main body, so water is unlikely to enter between the threaded portion and the thread teeth.

In addition, the refrigerator has a water drop receiving portion, which is located outside the main body below the cylindrical body and protrudes from the outer surface of the main body.

According to this structure, since the water drop receiving portion receives the water droplets dripping from the cylinder during drainage from the main body, the water droplets are less likely to flow down along the side wall of the main body, and the surface of the main body can be prevented from being soiled. [Effect of the invention]

Therefore, according to the present invention, a refrigerator that is easy to drain water can be provided.

Next, a refrigerator according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6. The refrigerator 1 is used when fishing, etc., and is mainly used to store the caught fish, cans or plastic bottles with drinks, etc. together with water or ice to keep them cold. In addition, the directions in the following description are shown in the directions shown in FIGS. 1 to 6.

The surface material of the bottom wall 21 or the side wall 22 is, for example, a synthetic resin such as polypropylene. The upper surface 210 of the bottom wall 21 of the present embodiment constitutes the inner bottom surface 26 of the main body 2.

The through hole 3 is provided for draining water from the inner side of the main body 2. In addition, the through hole 3 is located at the lower part 220 of the side wall of the main body 2. For example, the through hole 3 extends along the thickness direction of the side wall 22 of the main body 2. The shape of the through hole 3 corresponds to the shape of the barrel 5.

The inner surface 30 of the through hole 3 of the present embodiment is provided with a threaded tooth 31 for screwing the threaded portion 52 of the barrel 5. The threaded tooth 31 is provided at least partially in the circumferential direction of the through hole 3, for example, provided over the entire circumference of the through hole 3. In addition, the threaded tooth 31 is provided at least partially in the penetration direction of the through hole 3, for example, provided at the inner end portion of the through hole 3.

The barrel 5 is a member for limiting the drainage path of the water discharged when draining from the inner side of the main body 2. The barrel 5 of this embodiment is roughly cylindrical. In addition, the barrel 5 has: an outer peripheral surface 50 opposite to the through hole 3 of the main body 2, and an inner peripheral surface 51 that limits the drainage path.

Furthermore, the barrel 5 has a threaded portion 52 on the outer peripheral surface 50. The threaded portion 52 is provided at least partially in the circumferential direction of the barrel 5, for example, provided on the entire circumference of the barrel 5. In addition, at least partially in the inner and outer directions of the outer peripheral surface 50 of the barrel 5 is the threaded portion 52, for example, the inner end portion of the outer peripheral surface 50 is the threaded portion 52.

In addition, in the barrel 5, the inner circumferential surface 51 is a rotationally symmetrical shape, and specifically, the cross-sectional shape of the inner circumferential surface 51 is a circle. The lowest portion 510 of the inner circumferential surface 51, when the barrel 5 is arranged in the through hole 3 (for example, when the barrel 5 is screwed into the through hole 3), at least includes: an inclined surface that is inclined downward relative to the inner bottom surface 26 as the portion is located on the outer side. The lowest portion 510 of the inner circumferential surface 51 of the present embodiment, in addition to including: an inclined surface that is inclined downward relative to the inner bottom surface 26 as the portion is located on the outer side, also includes: a surface parallel to the inner bottom surface 26 of the main body 2. In addition, the lowest portion 510 of the inner circumferential surface 51 is a portion corresponding to the bottom of the inner circumferential surface 51.

Specifically, the cylinder 5 has: an adjacent portion 53 and a water guide portion 54; the adjacent portion 53 is adjacent to the inner bottom surface 26 of the main body 2 when the lowest portion 510 of the inner peripheral surface 51 is located at the same height as the inner bottom surface 26 of the main body 2; and the water guide portion 54 has a downwardly inclined portion facing outward on the outer side of the adjacent portion 53. At the lowest portion 510 of the inner peripheral surface 51 of the present embodiment, the adjacent portion 53 is adjacent to the inner bottom concave portion 260 of the inner bottom surface 26 of the main body 2, specifically, it is adjacent to the concave horizontal area 262 of the inner bottom concave portion 260.

The adjacent portion 53 of the present embodiment is, for example, a surface parallel to the inner bottom surface 26 of the main body 2 when viewed in a longitudinal section, and more specifically, a surface parallel to the placement surface of the refrigerator 1. In addition, the adjacent portion 53 is a surface parallel to the inner bottom surface 26 of the main body 2 in the vertical direction. Furthermore, the adjacent portion 53 is located at the inner end portion 56 of the cylinder body, and the inner end portion 56 of the cylinder body is an end portion located on the inner side of the cylinder body 5.

The water guide portion 54 of the present embodiment has an inclined portion, for example, a portion of the water guide portion 54 is an inclined surface. Specifically, at the lowermost portion 510 of the inner peripheral surface 51, the water guide portion 54 includes: a water guide horizontal area 540 located in the center in the inner and outer directions and horizontal to the placement surface of the refrigerator 1, an inner water guide inclined area 541 that is inclined and continuous with the water guide horizontal area 540 on the inner side, and an outer water guide inclined area 542 that is inclined and continuous with the water guide horizontal area 540 on the outer side.

The inclination of the inclined surface included in the water guide portion 54 may be different for each part in the inner and outer directions, or may be the same. In the water guide portion 54 of the present embodiment, the inclination of the inner water guide inclined area 541 is greater than the inclination of the outer water guide inclined area 542. The inclined surface included in the water guide portion 54 may be a flat inclined surface or a curved inclined surface when observed in a radial section. In the water guide portion 54 of the present embodiment, the inner water guide inclined area 541 or the outer water guide inclined area 542 is a flat inclined surface when observed in a radial section.

The cylinder covering portion 24 is provided to prevent water from intruding between the cylinder 5 and the inner surface 30 of the through hole 3. In addition, the cylinder covering portion 24 extends radially inwardly more than the thread teeth 31 of the through hole 3. The cylinder covering portion 24 of this embodiment is formed continuously in the circumferential direction.

The waterproof component 8 is provided to prevent water from intruding between the cylinder 5 and the inner surface 30 of the through hole 3. In addition, the waterproof component 8 is provided between the outer peripheral surface 50 of the cylinder 5 and the inner surface 30 of the through hole 3 of the main body 2.

The waterproof member 8 of this embodiment is provided in a pair, for example, at the inner end of the cylinder 5 and at a position further outward than the inner end. Specifically, the waterproof member 8 includes: an inner waterproof member 81 provided between the cylinder cover 24 of the main body 2 and the cylinder 5 along the inner surface 30 of the through hole 3, and an outer waterproof member 82 provided between the outer end 300 of the inner surface of the through hole 3 and the cylinder 5. The inner waterproof member 81 and the outer waterproof member 82 are both, for example, O-rings.

The water drop receiving part 7 is provided to receive the water drops dripping from the drainage of the main body 2. The water drop receiving part 7 of this embodiment comprises: a receiving main body part 70 located outside the main body 2 below the cylinder 5 and protruding from the outer surface 27 of the main body 2, and a receiving part mounting part 71 for mounting the receiving main body part 70 on the main body 2. In addition, the receiving main body part 70 and the receiving part mounting part 71 may be different bodies, but they are integrated in the water drop receiving part 7 of this embodiment.

The shape of the receiving main body 70 is, for example, a shape obtained by cutting a circular plate roughly in half. The receiving main body 70 is configured to be inclined so that the more outwardly located the part is, the farther away from the side wall 22. In addition, the receiving upper surface 700 of the receiving main body 70 is an inclined surface and is inclined so that the more outwardly located the part is, the lower it is. The receiving upper surface 700 is, for example, a flat inclined surface when observed in a radial section.

The shape of the receiving portion mounting portion 71 is a roughly square plate with a through hole 710 for the cylinder 5 to be inserted in the center (see Figure 4). The receiving main body portion 70 is connected to the center of the lower edge of the receiving portion mounting portion 71 in the horizontal direction.

The closing body 6 is a plug part that can open and close the end portion located on the outer side of the cylinder 5, that is, the outer end portion 55 of the cylinder. The closing body 6 of this embodiment has: a closing body part 60 as a cover of the outer end portion 55 of the cylinder, a waterproof sheet 61 and a pad 62 installed on the inner side of the closing body part 60 in a state of overlapping each other, a closing installation part 63 and a connecting shaft 64 for installing the closing body part 60 on the main body 2, and a closing gripping part 65 provided on the outer side of the closing body part 60.

When viewed from the outside, the shape of the closed main body 60 corresponds to the shape of the outer end 55 of the cylinder 5. For example, the closed main body 60 includes a circular plate-shaped closed circular plate 600 and a closed flange 601 extending inward from the outer edge of the closed circular plate 600. The closed circular plate 600 can close the outer end 55 of the cylinder from the outside. The closed flange 601 can cover the outer end 55 of the cylinder from the outside.

The waterproof sheet 61 and the gasket 62 are shaped to seal the outer end 55 of the cylinder 5, for example, a disc. The waterproof sheet 61 is made of a synthetic resin such as PTFE (polytetrafluoroethylene). The gasket 62 is made of rubber, for example.

The closed mounting portion 63 is in the shape of a roughly square plate with a through hole 630 in the center for mounting the closed main body 60. The upper portion 631 of the closed mounting portion 63 is inclined so that the upper portion is located more inward. The closed mounting portion 63 is rotatably mounted on the main body 2 via the water drop receiving portion 7 via the connecting shaft 64.

The closed gripping portion 65 is connected to the closed circular plate 600 of the closed main body 60. The closed gripping portion 65 of this embodiment includes: a circular gripping cover 650 corresponding to the shape of the closed circular plate 600, and a gripping main body 651 protruding outward from the gripping cover 650 and capable of being gripped by a user. The gripping main body 651 is, for example, in the shape of a strip.

The cover 9 is disposed between the outer peripheral surface 50 of the cylinder 5 and the heat insulating member 25 included in the side wall 22 of the main body 2. The cover 9 of the present embodiment is formed continuously in the circumferential direction of the cylinder 5. The cover 9 has the following function: it can withstand the pressure caused by the axial force generated when the cylinder 5 is screwed into the through hole 3, and does not apply a load to the heat insulating member 25 as much as possible.

The cover 4 is a cover part that can close the main body 2 (refer to FIG. 1). For example, the cover 4 is a roughly rectangular plate. In addition, the cover 4, like the bottom wall 21 or the side wall 22, has a surface material of a synthetic resin such as polypropylene (polypropylene), and contains a heat insulating member made of a foaming resin such as expanded polystyrene or polyurethane foam inside.

In the above refrigerator 1, since the adjacent portion 53 of the inner circumferential surface 51 of the cylinder 5 is located at the same height as the inner bottom surface 26 of the main body 2, the water stored in the main body 2 can be easily guided to the outside from the inner bottom surface 26 of the main body 2 through the adjacent portion 53 of the inner circumferential surface 51 of the cylinder 5 and the water guide portion 54, and therefore, it is easy to drain water from the main body 2 to the outside.

In the refrigerator 1 of the above embodiment, the cylinder 5 is mounted on the side wall lower portion 220 of the main body 2 by screwing the threaded portion 52 of the cylinder 5 and the threaded teeth 31 of the through hole 3, and therefore, it is not easy to fall off from the side wall lower portion 220.

In addition, in the refrigerator 1 of the above-mentioned embodiment, the cylinder 5 is covered by the cylinder cover 24 of the main body 2, and the threaded portion 52 of the cylinder 5 and the thread teeth 31 of the through hole 3 are not exposed to the inner side of the main body 2, so that water is not easy to enter between the threaded portion 52 and the thread teeth 31. In particular, in the refrigerator 1, the inner waterproof member 81 is provided between the cylinder cover 24 of the main body 2 and the cylinder 5, so that water can be prevented from entering between the threaded portion 52 and the thread teeth 31 from the inner side of the main body 2.

Furthermore, when the fish caught is stored in the refrigerator 1, the blood of the fish may be mixed in the drainage. When the water droplets of the drainage adhere to the side wall 22 of the main body 2, there is a concern that the side wall 22 may be soiled. However, in the refrigerator 1 of the above-mentioned embodiment, the water drop receiving portion 7 receives the water droplets dripping from the cylinder 5 in the drainage from the main body 2. Therefore, the water droplets are not likely to flow down along the side wall 22 of the main body 2, so that the outer surface 27 of the main body 2 can be prevented from being soiled.

In the refrigerator 1 of the above-mentioned embodiment, the cylinder 5 and the lower side wall portion 220 of the main body 2 are sealed by the waterproof member 8, thereby preventing drainage from the main body 2 from leaking to the outside from between the cylinder 5 and the lower side wall portion 220.

Furthermore, in the refrigerator 1 of the above-mentioned embodiment, an inner bottom recess 260 is provided on the inner bottom surface 26 of the main body 2, so that drainage from the main body 2 is guided to the inner bottom recess 260 and discharged to the outside through the inner bottom recess 260 and the adjacent portion 53 of the cylinder 5, thereby making it easier to drain water from the main body 2 to the outside.

In the refrigerator 1 of the above-mentioned embodiment, when the main body 2 is mounted on the cylinder 5, the cylinder 5 can be screwed into the through hole 3 of the main body 2 from the outside of the main body 2, so the assembly performance is excellent.

The present invention has been described by way of an embodiment, but the present invention is not limited to the embodiment described above. For example, the adjacent portion 53 of the cylinder 5 is adjacent to the inner bottom surface 26 of the main body 2 when the lowest portion 510 of the inner circumferential surface 51 is located at the same height as the inner bottom surface 26 of the main body 2, but may also be adjacent to the inner bottom surface 26 of the main body 2 when the lowest portion 510 of the inner circumferential surface 51 is located below the inner bottom surface 26 of the main body 2 as shown in FIG. 7 . That is, the cylinder 5 may also include: an adjacent portion 53 and a water guide portion 54; the adjacent portion 53 is adjacent to the inner bottom surface 26 of the main body 2 in a state where the lowest portion 510 of the inner peripheral surface 51 is located below the inner bottom surface 26 of the main body 2; and the water guide portion 54 has a downwardly inclined portion on the outer side of the adjacent portion 53. In this case, a step portion is generated between the inner bottom surface 26 of the main body 2 and the lowest portion 510 of the inner peripheral surface 51 of the cylinder 5. In such a structure, since the adjacent portion 53 of the inner circumferential surface 51 of the cylinder 5 is located below the inner bottom surface 26 of the main body 2, the water contained in the main body 2 can be easily guided to the outside from the inner bottom surface 26 of the main body 2 through the adjacent portion 53 of the inner circumferential surface 51 of the cylinder 5 and the water guide portion 54, so it is easy to discharge water from the main body 2 to the outside.

The adjacent portion 53 of the barrel 5 of the above-mentioned embodiment is a horizontal plane, but as shown in FIG. 8, it can also be a slope with a downward slope. In addition, the water guide portion 54 of the barrel 5 of the above-mentioned embodiment has a water guide horizontal area 540, but the entire area of the water guide portion 54 in the inside and outside direction can also be a slope with a downward slope. In this structure, it is considered to make the adjacent portion 53 and the water guide portion 54 as slopes with fixed inclinations. In this way, if the adjacent portion 53 is a slope with a downward slope, it is possible to drain water from the main body 2 to the outside more quickly.

In addition, the barrel 5 of the above-mentioned embodiment is installed in the through hole 3 by screwing the threaded portion 52 of the barrel 5 into the threaded teeth 31 of the through hole 3, but it can also be installed by other methods such as locking the barrel 5 and the through hole 3, pressing the barrel 5 into the through hole 3, and bonding the barrel 5 and the inner surface 30 of the through hole 3 with an adhesive. When locking the barrel 5 and the through hole 3, for example, it is considered to provide a claw on the barrel 5 and provide a recess on the inner surface 30 of the through hole 3 so that the claw and the recess are locked.

Furthermore, the barrel 5 of the above-mentioned embodiment is cylindrical, but may also be other shapes such as a square barrel. When the barrel 5 is a square barrel, it is considered that the cross-sectional shape of the inner peripheral surface 51 of the barrel 5 is a regular polygon such as a square. In addition, even when the barrel 5 is in other shapes such as a square barrel, the shape of the through hole 3 may be a shape corresponding to the shape of the barrel 5.

In the above-described embodiment, the inner bottom recess 260 is provided on the inner bottom surface 26 of the main body 2, but the inner bottom recess 260 may not be provided.
