Description

Cold insulation box

Technical Field

The present invention relates to a refrigerator capable of storing fish and the like in a cold-kept state, and more particularly to a refrigerator having a drain portion with a feature.

Background

In general, a cold box (cooling box) is carried to store ice, fish, and the like during fishing so that the fished fish can be carried in a cold state. In a state where the fish is kept cold, when water content increases due to melting of ice, etc., it is necessary to drain water. The drainage is performed by operating a drainage part disposed below the side wall of the cold insulation box body. As this drain portion, for example, as disclosed in patent document 1, a structure is known in which an opening is exposed by opening a screw-type cover that closes an opening formed in a side wall. The cover is provided with a T-shaped anti-drop part (anchor) passing through the opening part, so that the cover can not drop when the cover is removed and water flows out from the inside (including seawater).

In the above-described structure, there is a problem that the lid is soiled due to the water flowing out when the water flows out. Therefore, patent document 2 discloses a structure in which the lid body is rotated with respect to the main body during drainage so that the water flowing out does not flow onto the lid body in a state where the opening is opened.

Patent document 2: japanese patent No. 3669666

Disclosure of Invention

The drain unit disclosed in patent document 2 has a problem that operability is poor because a handle provided on the lid body needs to be grasped to rotate the handle in the clockwise direction or the counterclockwise direction when the lid body is opened and closed.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a refrigerator including a water discharge unit that can open and close a lid body with a simple operation without dirtying the lid body at the time of water discharge.

In order to achieve the above object, a cooling box according to the present invention includes a drain portion provided on a side wall of a main body to discharge water therein to the outside, the drain portion including: a cylinder which is communicated with the inside of the body and is used as a discharge flow path of water stored in the body; a support body integrated with the cylinder; and a cover body that is rotatably supported by the support body and opens and closes an opening of the cylindrical body, wherein the support body and the cover body are engaged with each other by an engagement unit that can elastically engage with each other, and the cover body is provided with an operation member that releases the elastic engagement of the engagement unit.

The cold insulation box with the above structure can make the water in the main body flow out to the outside by operating the cover body forming the drainage part. The drain unit includes a cylindrical body serving as a discharge flow path communicating with the inside of the main body, and a support body integrated with the cylindrical body, and the cover body is rotatably supported by the support body so as to open and close an opening of the cylindrical body. Since the support body and the lid body are engaged with each other by the engaging means capable of elastically engaging with each other, and the lid body is provided with the operation member for releasing the elastic engagement of the engaging means, the opening of the cylindrical body can be opened by a simple operation of releasing the elastic engagement only by operating the operation member, that is, by a simple operation of releasing the relationship of the engaged state by the elasticity against the urging force of the elasticity. Further, since the lid body is rotatably supported by the support body and can be avoided from the opening of the cylindrical body by rotation, the lid body can be prevented from being caught by water at the time of outflow, and therefore, the lid body is not soiled and the water inside can be discharged hygienically.

According to the present invention, a refrigerator in which the lid body is not contaminated during drainage and the lid body can be opened and closed with a simple operation can be obtained.

Detailed Description

Next, an embodiment of the cooling box according to the present invention will be specifically described with reference to the drawings.

Fig. 1 and 2 are views showing the entire configuration of an embodiment of a cooling box according to the present invention, fig. 1 being a perspective view, and fig. 2 being a view showing a side surface of the cooling box shown in fig. 1 on which a drain portion is provided.

The cold insulation box 1 includes: a body 3 of rectangular section having a heat insulating structure; and a lid 5 rotatably supported at an edge of the main body 3, closing an opening of the main body 3, and having a heat insulating structure. In this case, the lid 5 may be supported rotatably at 1 edge portion with respect to the main body 3, or may be supported rotatably at both 1 edge portion and an edge portion opposed to the edge portion (double-sided open structure). Further, a handle 7 for carrying the refrigerator is attached to the main body 3. In the present embodiment, since the roller 6 is attached to the bottom portion of the main body 3, and a carrying and conveying structure capable of carrying the roller is formed, the handle 7 may be attached to the edge portion of the short side of the main body 3, but may be attached to the lid 5.

The main body 3 is formed in a substantially rectangular parallelepiped shape, and includes a pair of short side walls 3A, a pair of long side walls 3B, and a bottom wall 3C (see fig. 4), a drain portion 10 is disposed below a central portion of the side wall 3A on one of the short side sides, and the drain portion 10 has a function of discharging water in the main body 3 to the outside. Next, the structure of the drain portion 10 of the present embodiment will be described with reference to fig. 3 to 9. In these drawings, fig. 3 is a perspective view showing the configuration of the drain portion, fig. 4 is a view of the cooling box body viewed from the inside and showing the outflow portion of the drain portion, fig. 5 is an exploded perspective view of a lid body constituting the drain portion, fig. 6 is an exploded perspective view showing the entire configuration of the drain portion, fig. 7(a) is a perspective view showing a state in which the lid body is closed, fig. 7(b) is a perspective view showing a state in which the lid body is opened, fig. 8 is a side sectional view of the drain portion, and fig. 9 is a bottom sectional view of the drain portion.

As shown in fig. 3 and 4, the drain portion 10 is disposed in a portion of the circular opening 3A formed on the lower side of the side wall 3A. On the bottom wall 3C, a recess 3C recessed downward is formed at a portion where the circular opening 3a is formed, so as to guide water toward the circular opening 3 a. The drain unit 10 disposed in the circular opening 3a is fitted into the circular opening 3a, and includes: a cylindrical tube 20 as a discharge passage for water stored in the main body; a support body 30 for holding the cylindrical body 20; and a cover 50 rotatably supported by the support 30.

The support 30 is made of, for example, a resin material, has a substantially rectangular shape with a circular opening 31 formed in the center thereof, and is closely arranged on the outer surface of the side wall 3A of the main body 3. The cylindrical body 20 is formed of a resin material, for example, as in the support body 30, and is fitted into the circular opening 31 of the support body 30. The cylindrical body 20 has a male screw portion 21 and a flange 22 formed on one end side and the other end side, respectively, and a rotation stop projection 23 formed therebetween at a predetermined angle in the circumferential direction. These rotation stopping projections are formed at substantially 90 ° intervals along the axial direction, and are formed in the 9 o 'clock, 12 o' clock, and 3 o 'clock directions by one, and in the 6 o' clock direction by 2.

The support 30 has a cutout 32 formed in a circular edge of the circular opening 31 to fit into the protruding piece 23. Therefore, the cylindrical body 20 is fitted into the circular opening 31 of the support body 30 by aligning the protruding piece 23 with the slit 32, and the cylindrical body 20 and the support body 30 are fixed by rotation stop. The cylindrical body 20 and the support body 30, which are integrated with each other, are fixed to the side wall 3A of the main body 3 by closely fitting the support body 30 to the outer surface of the side wall 3A, and in this state, screwing the ring member 25, on which the female screw 25a is formed, into the male screw 21 of the cylindrical body 20 protruding to the inside of the main body. At this time, an O-ring 26 is interposed between the ring member 25 and the inner surface of the side wall 3A to prevent water leakage. Further, since the slit 3e is formed at a corresponding position in the peripheral edge portion of the opening 3A of the main body 3A so as to fit the projecting piece 23 formed in the cylindrical body 20, the ring member 25 can be easily and stably attached.

The cylindrical body 20 and the support body 30 may be formed separately in advance and integrated by mechanical bonding, adhesion, or the like as described above, or may be integrally formed (integrated) by resin molding.

A pair of support portions 34 are formed to protrude from both sides of the upper end of the support body 30. Each support portion 34 is formed with a support hole 34a to which a support shaft 53 described later is attached. A pair of side walls 35 are formed on both sides of the support 34, and an engaging portion 35a is formed below each side wall 35.

The engaging portion 35a may be a recess (including an opening) and may form an engaging means that can be elastically engaged with the cover 50, and thus has a function of holding the cover 50 in an elastically engaged state (a state in which the cover 50 is fixed to the support 30). In each side wall 35, an inclined guide surface 35b is formed on the engagement portion 35a so as to guide a locking claw described later.

The cover 50 is rotatably supported by the support 30, and the cover 50 opens and closes the opening 20A on the outside of the cylindrical body 20. The main body 50A of the lid body 50 is integrally formed of, for example, a resin material, and includes a substantially rectangular frame portion 51 and a raised portion 52 raised in a dome shape. Notches 51b are formed at both sides of the upper surface of the frame 51 so that the pair of support portions 34 of the support 30 are inserted.

Support holes 51a are formed in both upper ends of the frame portion 51 so as to correspond to the support holes 34a of the support portions 34 formed to protrude from the support body 30, and a support shaft 53 is disposed in this portion, whereby the lid body 50 is supported by the support body 30 so as to be rotatable in the vertical direction. The support shaft 53 is disposed so as to pass through the pivot spring 54, and the lid 50 is constantly urged by the urging of the pivot spring 54 in a direction (arrow direction in fig. 8) in which the lid opens upward around the support shaft 53. That is, since the pivot spring 54 includes the contact portions 54a formed at both ends of the spring portion and the contact portion 54b formed at the center of the spring portion, the contact portions 54a at both ends abut against the support body 30, and the contact portion 54b at the center abuts against a plate described later, the lid body 50 is always urged in a direction in which it opens upward around the support shaft 53.

A pair of substantially trapezoidal openings 52a are formed on the left and right sides of the raised portion 52. In each of the openings 52a, an operation member (operation lever) 55 formed by, for example, resin molding is disposed. Each of the operation members 55 is formed in a concave shape so that a finger can be inserted, and each of the operation members 55 is provided with a vertical wall 55a so that both the operation members can be sandwiched by the finger (sandwiched by the index finger and the thumb). Further, on the side portions of the operation members 55 facing each other, circular openings 55b are formed respectively, and in the portions, pressing springs 57 are arranged so as to urge the operation members 55 facing each other in the direction away from each other. A pair of guide portions 52b are integrally formed on the upper and lower sides of the back surface of the raised portion 52, and the plate-shaped portion 55d of the operation member 55 is positioned at this portion and holds the operation member 55 so as to be movable only in the left-right direction.

That is, by inserting 1 pressing spring 57 into the circular opening 55b of the two operation members 55, the two operation members 55 can be pinched by fingers and moved in a direction to approach each other against the urging force, and when not pinched by fingers, the two operation members 55 can be held in a state of being urged in a direction to be separated from each other by the urging force of the pressing spring 57. In this way, since the engaged state is formed by biasing the pair of operation members 55 in the direction away from each other by 1 pressing spring, even if one of the operation members is pushed in the releasing direction by an erroneous operation, the other operation member is kept pushed in the biasing direction of the pressing spring, and therefore, the engaged state is not released, and therefore, the opening of the lid body by the erroneous operation can be reliably prevented. In addition, by inserting 1 pressing spring between the two members, the structure can be simplified, and the mounting work can be facilitated.

Of course, the respective operation members may be provided with pressing springs for urging the operation members in directions away from each other.

Each of the operating members 55 is provided with a claw with projection 55e engageable with an engaging portion 35a formed on the side wall 35 of the support 30. In a state where the operation members 55 are urged in directions away from each other by the urging force of the pressing spring 57, the projecting claws 55e are guided by the inclined guide surfaces 35b, and can be engaged with the engaging portions 35a against the urging force. That is, the protruding claws 55e of the operating member 55 and the engaging portions (recesses) 35a of the support 30 that receive the protruding claws 55e constitute engaging means, and the two protruding claws 55e are urged by the pressing springs 57 in the direction of engaging with the engaging portions 35 a.

Therefore, when the lid body 50 is closed to the support body 30 against the urging force of the pivot spring 54, the projecting pawl 55e is engaged with the engaging portion 35a by the urging force (elastic force) of the pressing spring 57. Further, the elastic engagement between the two operation members 55 can be easily released by operating the two operation members 55 against the urging force of the pressing spring 57 (pinching operation), and the lid body 50 is rotationally driven with respect to the support body 30 as it is by the urging force of the rotational spring 54.

In addition, any one of the engaging means provided on the support body 30 and the operating member 55 may be a claw (projection), and the engaging relationship may be an engaging relationship between the claw and the concave portion, or a relationship in which the convex portions are engageable with each other. For example, as shown in fig. 10, a convex portion 35f may be formed in advance on the side wall 35 of the support 30, and the above-described protrusion-equipped claw 55e may be engaged with this portion.

A plurality of screw holes 60 are formed in the cover 50 to which the operation member 55 is attached. These screw holes 60 are formed to protrude from the back surface side of the raised portion 52 in a direction orthogonal to the side wall 3A, and in the present embodiment, 4 positions are formed at four corners of the lid body 50. A plate-shaped plate 65 can be attached to the cover 50 by screwing a screw (not shown) into the screw hole 60, and the inside of the frame portion 51 is closed by the attachment plate 65, whereby the pair of operation members 55 are held in a slip-off manner.

At this time, half-i-shaped cutouts 65a are formed in the plate 65 on the left and right sides, respectively, so that the protruding claws 55e of the two operation members 55 closed by the plate 65 are exposed. When the plate 65 is attached to the cover 50, the pivot spring 54 is exposed, and the center contact portion 54b abuts against the upper end edge 65b of the plate 65.

A circular projection 65c is integrally formed on the exposed surface when the plate 65 is attached so as to be fitted into the opening 20A of the cylindrical body 20, and a cover 66 made of rubber or silicone is preferably provided in advance on the circular projection 65c, whereby, when the lid body 50 is closed, sealability is ensured between the lid body 50 and the opening 20A of the cylindrical body 20, and the cover 66 is in close contact with the opening 20A, thereby reliably preventing water leakage.

Next, the operation of the drain portion 10 attached to the side wall 3A of the main body 3 as described above will be described.

In a normal state of the refrigerator, the lid 50 is engaged with the support 30 against the urging force of the pivot spring 54 (see fig. 7 a, 8, and 9). At this time, the cover 66 of the plate 65 attached to the main body 50A of the lid 50 is closely fitted to the opening 20A of the cylinder 20, and the water inside does not leak to the outside (closed state of the lid). In this state, since the pair of protruding claws 55e formed on the operation member 55 of the lid 50 are elastically engaged with the engagement portion (concave portion) 35a of the support 30, the rotation of the lid 50 is prevented, and the drain portion is not opened.

In draining, the vertical walls 55a of the pair of operation members 55 are gripped by fingers (between the index finger and the thumb). At this time, the operation members 55 move in the direction of approaching each other against the urging force of the pressing spring 57, and the protruding claws 55e of the operation members 55 are disengaged from the engagement portions (recesses) 35a of the support 30. Thereby, the engagement between the lid 50 and the support 30 is released, and the lid 50 is rotated in the arrow direction of fig. 8 by the biasing force of the rotating spring 54, whereby the lid 50 is opened (the opening 20A of the cylindrical body 20 is opened) as shown in fig. 7 (b). In this state, the water in the main body 3 can be discharged to the outside through the cylindrical body 20.

In the present embodiment, the rotation of the lid 50 is restricted by abutting both edges 51c of the frame portion 51 of the lid 50 against the upper end stepped portion 35d of the side wall 35 formed on the support 30, and the rotation of the lid 50 is restricted to a position of substantially 90 ° with respect to the support 30 (side wall 3A).

As described above, since the lid 50 can be rotated in the vertical direction and fixed in a substantially horizontal position only by the biasing force of the rotating spring 54 without the need of a finger-lifting operation at the time of water discharge, the lid 50 can be automatically avoided from the outflow path at the time of water discharge by tilting the main body 3, and the outflow water is prevented from contacting the lid 50, so that the water inside can be discharged hygienically. Further, since the support 30 and the cover 50 are engaged with each other by the engagement means capable of elastic engagement, and the cover 50 is provided with the operation member 55 for releasing the elastic engagement of the engagement means, the opening 20A of the cylindrical body 20 can be opened only by releasing the elastic engagement by operating the operation member 55 (in the present embodiment, a simple operation of merely pinching the pair of operation members 55).

In the above configuration, the support body 30 and the lid body 50 can be positioned with reference to the support shaft 53 supported by the support portion 34 formed in the support body, and therefore, the engagement means, i.e., the protruding claws 55e and the engagement portions (concave portions) 35a can be engaged with high accuracy. That is, since the mounting accuracy is improved as compared with the configuration in which one of the engaging means is provided on the side of the main body 3 to which the drain unit is mounted, the engaging accuracy of both is improved, and thus the stable open/close state of the lid body 50 can be ensured. Further, when the lid 50 is closed, the engagement means can be held in the engaged state only by a simple operation of rotating the lid 50 toward the support 30 against the urging force of the rotating spring 54 and pressing it into the support 30, and therefore the closing operation can be easily performed.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made.

Although the operation member 55 is configured in the form of a pair of operation levers that are pinched and pressed against each other in the above-described embodiment, it may be configured by a single operation lever that is engaged with the support body 30 by the engagement means described above. For example, as shown in fig. 11 and 12, the operation member 55 may be disposed only on one side of the raised portion 52 of the cover 50. In such a configuration, a holding wall 91 having a holding portion 90 is provided on the back surface of the main body 50A of the lid body, and the holding portion 90 holds the base end portion of the pressing spring 57 while abutting against the base end portion, and urges the single operation member 55 in the direction of arrow D in fig. 12, and further engages the engagement means (the protruding claw 55e and the recess 35a) by the urging. With this configuration, the operation and structure for opening the lid body can be simplified. The cover 50 may be provided with no holding wall as described above, and the pressing spring 57 may be directly abutted against the frame 51, or an abutting portion may be locally formed in advance, and the pressing spring 57 may be abutted against the abutting portion.

As shown in fig. 13 and 14, the operation member 55A may be movable in the vertical direction, and may be configured to be pressed and urged so that the engagement unit (not shown) is brought into an engaged state downward. In such a configuration, the engagement of the engaging means is released by a finger being pressed against the operation wall 55b of the operation member 55A and a lifting operation (lifting operation) of the operation member 55A in the direction of arrow D1 against the biasing force. In this way, the operation direction of the operation member can be appropriately changed, and a configuration may be adopted in which the engagement state of the engagement means is released by a push-button type operation member being pushed or a convex member being slid. The shape of the lid may be circular or the like, and is not particularly limited.
