  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). At the lower side, a water draining portion 10 having a function of discharging the water inside the main body 3 to the outside is disposed. Hereinafter, the structure of the water draining part 10 of this embodiment is demonstrated with reference to FIGS. 3-9. In these figures, FIG. 3 is a perspective view showing the structure of the water draining portion, FIG. 4 is a view of the cold storage box main body seen from the inside, a view showing the outflow portion of the water draining portion, FIG. 6 is an exploded perspective view showing the entire structure of the water draining part, FIG. 7 (a) is a perspective view showing the lid closed, and FIG. 7 (b) is a lid FIG. 8 is a side cross-sectional view of the draining portion, and FIG. 9 is a bottom cross-sectional view of the draining portion.

  As shown in FIGS. 3 and 4, the water draining portion 10 is disposed in a portion of a circular opening 3 a formed on the lower side of the side wall 3A. In the bottom wall 3C, a recess 3c recessed downward is formed in a portion where the circular opening 3a is formed, so that water can be easily guided toward the circular opening 3a. The water draining portion 10 disposed in the circular opening 3a is inserted into the circular opening 3a, and a cylindrical cylindrical body 20 serving as a discharge flow path for water accumulated inside the main body, and a support for holding the cylindrical body 20 30 and a lid 50 rotatably supported relative to the support 30.

  The support 30 is made of, for example, a resin material, and is formed in a substantially rectangular shape with a circular opening 31 formed at the center, and is disposed in close contact with the outer surface of the side wall 3A of the main body 3. The cylindrical body 20 is formed of, for example, a resin material as in the case of the support 30, and is fitted into the circular opening 31 of the support 30. A male screw portion 21 is formed on one end side of the cylindrical body 20, and a flange 22 is formed on the other end side, and a projection 23 for rotation prevention is formed at a predetermined angle in the circumferential direction between them. Is formed. These anti-rotation protrusions are formed along the axial direction at intervals of approximately 90 °, and one is formed in the 9 o'clock, 12 o'clock, 3 o'clock directions, and two in the 6 o'clock direction.

  In the support 30, a notch 32 in which the protrusion 23 is fitted is formed at a circular edge of the circular opening 31. Therefore, by positioning the projecting piece 23 and the notch 32 and inserting the cylindrical body 20 into the circular opening 31 of the support 30, the cylindrical body 20 and the support 30 are rotationally fixed. And the cylindrical body 20 and the support body 30 which integrated both arrange | position the support body 30 in close contact with the outer surface of 3 A of side walls, and the external thread of the cylindrical body 20 which protrudes in the inside of a main body in this state The support 30 is fixed to the side wall 3 </ b> A of the main body 3 by screwing the ring member 25 in which the female screw 25 a is formed in the portion 21. In this case, an O-ring 26 is interposed between the ring member 25 and the inner surface of the side wall 3A to prevent water leakage. Also, a notch 3e is formed at a corresponding position on the peripheral edge of the opening 3a of the main body 3A so that the projecting piece 23 formed on the cylinder 20 can be fitted therein, making the ring member 25 easy and stable. It is configured to be able to be worn.

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

On both sides of the upper end of the support 30, a pair of support portions 34 are formed to protrude. A support hole 34a is formed in each support portion 34, and a support shaft 53 described later is attached to this portion. Further, on both sides of the support 34, a pair of side walls 35 are formed, and on the lower side of each side wall 35, engaging portions 35a are respectively formed.
The engagement portion 35a may be a recess (including an opening), and constitutes an engagement means that can be resiliently engaged with the lid 50, and the lid 50 is resiliently engaged. It has a function to hold in the state (the state where the lid 50 is fixed to the support 30). Further, on each side wall 35, an inclined guide surface 35b is formed in the engaging portion 35a so as to guide a locking claw described later.

  A lid 50 for opening and closing the opening 20A on the outside of the cylindrical body 20 is rotatably supported on the support 30. The main body 50A of the lid 50 can be integrally formed of, for example, a resin material, and includes a substantially rectangular frame 51 and a bulging portion 52 that bulges in a dome shape. Notches 51 b are formed on both sides of the upper piece of the frame 51 so that the pair of support portions 34 of the support 30 can enter.

  Support holes 51a are formed at upper ends on both sides of the frame 51 so as to correspond to the support holes 34a of the support portion 34 formed to project from the support 30, and the support shaft 53 is disposed in this portion As a result, the lid 50 is rotatably supported in the vertical direction with respect to the support 30. The support shaft 53 is disposed so as to insert the rotation spring 54, and the lid 50 always opens upward around the support shaft 53 by the biasing force of the rotation spring 54 (see FIG. It is biased in the arrow direction). That is, the pivoting spring 54 includes an attaching portion 54a formed at both ends of the spring portion and an attaching portion 54b formed at the center of the spring portion. The center contact portion 54b is applied to a plate described later, so that the lid 50 is always biased upward in the direction of the support shaft 53.

  The bulging portion 52 is formed with a pair of substantially trapezoidal openings 52 a on the left and right. An operating member (operating lever) 55 formed by, for example, resin molding is disposed in the opening 52a. Each operation member 55 is formed in a concave shape so that a finger can be inserted, and is provided with a vertical wall 55a so that both operation members can be pinched (sandwich between index finger and thumb). Further, circular openings 55b are respectively formed on mutually facing side portions of the operation member 55, and a pressing spring 57 is disposed in this portion to bias the operation members 55 in a direction to separate from each other. There is. The pair of guide portions 52b are integrally formed on the upper and lower sides of the back surface of the bulging portion 52, and the plate-like portion 55d of the operation member 55 is positioned at this portion, so that the operation member 55 only in the left-right direction Hold to be able to move to

That is, by interposing one pressing spring 57 in the circular opening 55b of both operation members 55, both operation members 55 can be pinched with a finger and moved in a direction approaching each other against the biasing force. In addition to the above, when the finger is not gripped, it is held in a state of being biased in a direction away from each other by the biasing force of the pressing spring 57. In this manner, by urging the pair of operating members 55 in a direction away from each other by one pressing spring to bring them into an engaged state, even if one operating member is pushed in the release direction by mistake, the other Since the operation member is not pushed in the direction of biasing force of the pressing spring and the engaged state is not released, it is possible to reliably prevent the lid from being opened due to an erroneous operation. Further, by interposing one pressing spring between both members, the structure is simplified and the assembling operation becomes easy.
Of course, pressing springs may be disposed on the respective operation members and may be biased in directions away from each other.

  Each of the operation members 55 is formed with a projection with claw 55e that can be engaged with an engagement portion 35a formed on the side wall 35 of the support 30. The claws 55e with protrusions are guided against the biasing guide surface 35b against the biasing force in a state in which the operation members 55 are biased in the direction away from each other by the biasing force of the pressing spring 57, and the engaging portions 35a are engaged. Can be engaged. That is, the projecting claw 55e of the operation member 55 and the engaging portion (recessed portion) 35a of the support 30 receiving the same constitute engaging means, and the both projecting claws 55e are engaged by the pressing spring 57. It is biased in the direction to engage with 35a.

Therefore, when the lid 50 is closed against the support 30 against the biasing force of the rotation spring 54, the projection claw 55e engages with the engagement portion 35a by the biasing force (elastic force) by the pressing spring 57. Do. Further, by operating (plucking operation) both operating members 55 against the biasing force of the pressing spring 57, the elastic engagement between the both can be easily released, and the lid 50 is rotated as it is. It is rotationally driven with respect to the support 30 by the biasing force of 54.
Note that any of the engagement means provided on the support 30 and the operation member 55 may be a claw (protrusion), and the engagement relationship may be an engagement relationship between the claw and the recess. Alternatively, the protrusions may be engaged with each other. For example, as shown in FIG. 10, a convex portion 35f may be formed on the side wall 35 of the support 30, and the above-described projection with claw 55e may be engaged with this portion.

A plurality of screw holes 60 are formed in the lid 50 into which the operation member 55 is incorporated. These screw holes 60 are formed so as to protrude in a direction orthogonal to the side wall 3A from the back surface side of the bulging portion 52, and in the present embodiment, four places are formed at four corners of the lid 50. A plate-like plate 65 is attached to the lid 50 by screwing a screw (not shown) into the screw hole 60, and the frame portion is attached by attaching the plate 65. The inside of 51 is closed, and the pair of operation members 55 are retained and held.
In this case, U-shaped notches 65a are formed on the left and right sides of the plate 65 so that the projecting claws 55e of the both operation members 55 closed by the plate 65 are exposed. In addition, when the plate 65 is attached to the lid 50, the pivot spring 54 is exposed, and the center abutting portion 54b abuts on the plate 65 upper end edge 65b.

A circular projection 65c is integrally formed on the exposed surface when the plate 65 is attached so as to fit in the opening 20A of the cylinder 20. The circular projection 65c is a cover made of rubber or silicon 66 is preferably provided, whereby when the lid 20 is closed, sealing performance is secured between the lid 20 and the opening 20A of the cylinder 20, and the cover 66 closely contacts the opening 20A to cause water leakage. It becomes possible to prevent reliably.

Next, the operation of the water draining portion 10 mounted on the side wall 3A of the main body 3 as described above will be described.
In the normal state of the cold storage box, the lid 50 is engaged with the support 30 against the biasing force of the pivot spring 54 (see FIGS. 7A, 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 (the lid Occlusion). Further, in this state, since the pair of projecting claws 55e formed on the operation member 55 of the lid 50 elastically engages with the engagement portion (recessed portion) 35a of the support 30, the lid 50 Rotation is prevented, and the drainage part is not opened.

  When draining water, the vertical walls 55a of the pair of operation members 55 are pinched with a finger (squeezed with a forefinger and a thumb). At this time, the operation members 55 move in the direction approaching each other against the biasing force of the pressing spring 57, and the projection claws 55e of the operation members 55 move from the engaging portion (recessed portion) 35a of the support 30. Get out. As a result, the engagement relationship between the lid 50 and the support 30 is released, and the lid 50 is pivoted in the direction of the arrow in FIG. 8 by the biasing force of the pivot spring 54, as shown in FIG. The lid 50 is opened (the opening 20A of the cylinder 20 is released). In this state, the water in the main body 3 can be drained to the outside through the cylinder 20.

  In the present embodiment, the two edges 51c of the frame 51 of the lid 50 abut on the upper end step 35d of the side wall 35 formed on the support 30, whereby the rotation of the lid 50 is restricted. The rotation of the lid 50 is restricted at a position of approximately 90 ° with respect to the support 30 (side wall 3A).

  As described above, at the time of draining, the cover 50 is vertically rotated only by the biasing force of the rotation spring 54 without being lifted with a finger and fixed at a substantially horizontal position. In the case of tilting and draining, the lid 50 is automatically retracted from the outflow path, and it is possible to prevent the outflowing water from touching the lid 50, and the water inside can be hygienically released. Further, the support 30 and the lid 50 are engaged by the elastically engageable engagement means, and the lid 50 is provided with the operation member 55 for releasing the elastic engagement by the engagement means. The opening 20A of the cylindrical body 20 can be opened only by operating the operation member 55 (in this embodiment, a simple operation of simply pinching the pair of operation members 55) to release the elastic engagement.

  Further, in the above-described configuration, since the support 30 and the lid 50 can be positioned with reference to the support shaft 53 supported by the support portion 34 formed on the support, the support 30 and the cover 50 are engaged with the protuberance with the projection 55e. It is possible to engage the mating portion (recess) 35a with high accuracy. That is, as compared with the configuration in which one of the engagement means is provided on the side of the main body 3 to which the water draining portion is attached, the mounting accuracy is improved, so that the engagement accuracy of both is improved. It can be secured. Furthermore, when closing the lid 50, the lid 50 is pivoted toward the support 30 against the biasing force of the pivot spring 54, and the lid 50 is engaged by a simple operation of pressing the support 30. The coupling means can be held in the engaged state, and the closing operation can be easily performed.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It is possible to deform | transform variously.

  In the embodiment described above, the operation member 55 is configured to be pinched to each other in the form of a pair of levers, but is configured as a single lever engaged with the support 30 by the engagement means as described above It is good. For example, as shown in FIGS. 11 and 12, the operation member 55 may be disposed only on one side of the bulging portion 52 of the lid 50. In such a configuration, a holding wall 91 provided with a holding portion 90 for housing the base end side of the pressing spring 57 and holding the base end in contact is provided on the back surface of the main body 50A of the lid. One operation member 55 is biased in the direction of arrow D in FIG. 12, and the engagement means (the projection claw 55e and the recess 35a) are engaged by the biasing force. With such a configuration, the operation and structure of opening the lid can be simplified. In addition, without providing the above-mentioned holding | maintenance wall in the cover body 50, the press spring 57 can be contact | abutted to the frame part 51 as it is, or a contact part is partially formed and it is made to contact here. Also good.

  Further, as shown in FIGS. 13 and 14, the operation member 55A can be moved in the up and down direction, and it is configured to push downward so that the engagement means (not shown) is engaged. It is good. In such a configuration, a finger is placed on the operation wall 55b of the operation member 55A, and the engagement member is released from the engagement by raising the operation member 55A in the direction of the arrow D1 against the biasing force. Configured as. As described above, the operation direction of the operation member can be appropriately modified, and in addition to this, the button-type operation member can be pushed in or the convex member can be slid. The configuration may be such that the united state is released. Furthermore, the shape of the lid is not particularly limited, for example, circular.
