Usually, in the main body case of this kind of storage, the opening edges of the outer box and the inner box are inserted and joined to the joining groove provided in the decorative frame. At the time of joining, a sealing member such as a waterproof tape or a caulking agent is interposed between the joining groove and the opening edge portion. Therefore, if the seal member is not properly inserted during manufacturing or if there is a joint part where the seal is incomplete due to aging of the seal member, dew condensation water may enter the filling space from the part. .. In the refrigerator of Patent Document 1, since the dew condensation water dripping from the outer door is received by the trough and drained to the water storage tank, it is possible to prevent water leakage to the inside of the refrigerator below the main body and the floor surface. However, no drainage measures are taken for the condensed water that has entered the filling space from the joint where the seal is incomplete. Therefore, when dew condensation water enters the filling space, the dew condensation water flows down a small gap between the inner surface of the filling space and the heat insulating material, and the dew condensation water accumulates at the bottom of the filling space, so that various bacteria propagate in the dew condensation water. It is not good for hygiene. If the outer box, which is the bottom of the filling space, has an opening for drawing a pipe or the like into the seam or inside the main body, dew condensation water will flow out of the filling space to the inside of the refrigerator or Water may leak to the floor.

Specifically, the drainage receiver 40 includes a drainage receiver main body 44 and a water collecting frame 45.

As shown in FIGS. 4 and 6, the drainage receiving main body 44 includes a water collecting tray 41 provided on the rear side of the upper surface of the drainage receiving main body 44, and a support wall 48 extending from the upper end rear edge of the water collecting tray 41. A flange wall 49 horizontally extending from the upper edge front edge of the water collecting tray 41, left and right edges of the water collecting tray 41 and the flange wall 49, and a cover wall 50 extending downward from the front edge of the flange wall 49. It has and. The support wall 48 is formed so as to incline downward toward the front side, and the upper surface of the support wall 48 and the inner surface of the rear wall of the water collecting tray 41 are smoothly continuous. Brackets 51 for fastening and fixing the drainage receiver 40 to the front surface of the lower outer box end frame 28 are fixed to the inner surfaces of the left and right rear sides of the cover wall 50 (see FIG. 4 ).

As shown in FIG. 4, the combined front and rear dimensions of the water collecting tray 41 and the flange wall 49 are set so that the front edge thereof is substantially at the same position as the front surface of the door 2. The dimensional ratio with respect to 49 in the front-rear direction is set to about 2:3. The left-right dimension is set to be substantially the same as the left-right dimension of the door 2 (see FIG. 2). Most of the dew condensation water oozing out from the gap between the magnet packing 2a and the frame main body 34 drips from the rear edge portion of the lower surface of the door 2, so that almost all the dew condensation water dripping from the door 2 is received by the water collecting tray 41. .. However, a part of the water drops from the middle part of the lower surface of the door 2, but since it is received by the flange wall 49, water does not leak to the floor surface. Although the front-rear dimension of the water collecting tray 41 is set smaller than the front-rear dimension of the flange wall 49, the dimensional relationship between the both 41 and 49 may be reversed, and the entire upper surface of the drainage receiving main body 44 may be collected. The flange wall 49 may be omitted as the water tray 41.

The lower hinge shaft 12 is supported on the left side of the flange wall 49, and as shown in FIG. 6, the flange wall 49 has an insertion hole 55 for inserting the hinge shaft 12 from the lower side.

Can be made smaller. Therefore, the water collecting tray 41 and the flange wall 49 can be brought close to the lower surface of the door 2, and the condensed water dripping from the door 2 can be reliably received by the water collecting tray 41 and the flange wall 49.

As shown in FIGS. 4 and 6, a drainage hole 52 is provided in the bottom wall of the water collecting tray 41 near the right end, and a connection tube for connecting a drainage hose 53 is provided below the drainage hole 52. 54 is fixed. As described above, when the drain hole 52 is provided in the bottom wall of the water collecting tray 41, the condensed water received by the water collecting tray 41 does not overflow from the water collecting tray 41 and can be prevented from leaking to the floor surface. .. Further, since it is not necessary to increase the volume of the water collecting tray 41 as much as the amount of dew condensation water is discharged, it is possible to prevent the drainage receiving main body 44 from being unnecessarily large and to improve the appearance of the storage cabinet.

As shown in FIGS. 1 and 6, the water collecting frame 45 includes a water collecting wall 42 and a joining wall 58 extending upward at the front edge of the water collecting wall 42. It is inserted into the joining groove 36 of the unit frame body 33 and joined. The water collecting wall 42 is formed so as to be inclined downward toward the front side, and a water blocking wall 59 for blocking the dew condensation water is extended upward at the left and right ends of the water collecting wall 42. The front edge of the water blocking wall 59 is welded and fixed to the joint wall 58. At the front end of the water collecting wall 42, a downflow hole 60 for passing the condensed water received by the water collecting wall 42 is provided in a penetrating manner, and the downflow holes 60 are arranged at regular intervals along the left-right direction of the water collecting wall 42.

Fastening pieces 61 for fastening and fixing the drainage receiver 40 to the inner surfaces of the left and right outer box end frames 28 are provided at the upper and left edges of the joining wall 58. The inner dimension of the left and right fastening pieces 61 is set to be equal to or slightly larger than the left-right dimension of the lower unit frame body 33.

As described above, when the water collecting wall 42 is formed in a state of being inclined downward toward the front side and the downflow hole 60 is provided near the tip of the water collecting wall 42, the condensed water received by the water collecting wall 42 is surely provided. By guiding the water to the downflow hole 60, the dew condensation water that has entered the filling space can be more reliably discharged to the water collecting tray 41. Further, by providing the water blocking walls 59 for blocking the condensed water on the left and right ends of the water collecting wall 42, the condensed water is surely prevented from leaking to the filling space from the left and right ends of the water collecting wall 42, and the condensed water is condensed. Can be guided to the downflow hole 60 more reliably and drained.

As shown in FIG. 1, the water collecting frame 45 has its water collecting wall 42 in contact with the support wall 48 and is supported from below. In this state, the water collecting wall 42 near the rear end and the support wall 48 are spot-welded, and the welding points are provided at regular intervals along the left-right direction. Therefore, the lower surface of the water collection wall 42 and the upper surface of the support wall 48 are not completely in close contact with each other, and the flow-down slit 62 is formed between the both walls 42 and 48 with a small gap such that condensed water can flow down. Are formed. In this embodiment, the flow-down portion 43 is composed of the above-mentioned flow-down hole 60 and the flow-down slit 62 provided in the water collection wall 42.

According to the drain receiver 40 as described above, the dew condensation water that has entered the filling space can be surely received by the water collection wall 42 by flowing down along the inner surface of the joint wall 58, and the received dew condensation water It can be made to flow down to the water collecting tray 41 via the downflow hole 60 and the downflow slit 62. Therefore, the dew condensation water that has entered the filling space can be reliably drained to the water collecting tray 41.

When assembling the case main body 1, first, the water collecting frame 45 is aligned with the left and right end portions of the water collecting frame 45 of the drainage receiver 40 aligned with the notches 28a provided in the lower ends of the left and right outer box end frames 28. It is inserted and temporarily fixed in a state where the front surface of the outer box end frame 28 and the front surface of the joint wall 58 are flush with each other. In this state, the fastening pieces 61 are fastened and fixed to the inner surfaces of the left and right outer box end frames 28 with rivets (blind rivets) 64 from the front side. Next, the drainage receiver 40 is integrated with the outer casing 23 by fastening and fixing the bracket 51 to the lower outer casing end frame 28 with the screws 65 from the front side. After that, the outer box 23 and the inner box 24 are joined with the decorative frame 25. In the upper, left and right unit frame bodies 33, the outer box end frame 28 and the inner box end frame 30 are inserted into the pair of joint grooves 36, respectively. In the lower unit frame 33, the inner box end frame 30 is inserted into one joint groove 36, and the joint wall 58 of the drainage receiver 40 is inserted into the other joint groove 36. As a result, both boxes 23 and 24 are integrated with each other in a state where the filling space between the outer box 23 and the inner box 24 is formed. Finally, the undiluted two-component urethane foam liquid is poured into the filling space from a filling hole (not shown), and is foamed and solidified in the filling space, so that the heat insulating material 26 can be filled in the filling space. 1 is completed.

When the heat insulating material 26 is filled, urethane foam is foamed and solidified in the filling space, so that the heat insulating material 26 is filled up to the inside of the downflow hole 60 as shown in FIG. However, since there is a slight gap between the inner surface of the filling space, the water collecting wall 42, etc. and the heat insulating material 26, the condensed water flows down along the gap. Therefore, even when the heat insulating material 26 is filled up to the inside of the downflow hole 60, the dew condensation water that has infiltrated into the filling space is drained to the outside of the filling space from the downflow portion 43 configured by the downflow hole 60 and the downflow slit 62.

The drainage receiver 40 of this embodiment is applied when the decorative frame 25 is arranged near the front edge of the inner surface of the cooling chamber 4, and the upper end of the joint wall 58 is bent rearward. The point that the front and rear dimensions of the water collection wall 42 and the support wall 48 are set to be long is different from the previous embodiment. In the inner box 24, the opening front edge of the inner box body 29 functions as an inner box end frame 30. Since the decorative frame 25 is arranged on the inner surface of the cooling chamber 4, it is not necessary to adsorb the magnet packing 2a of the door 2, so the band plate 37 of the frame body 34 is omitted. As described above, the present invention can be applied to the quick cooling box in which the decorative frame 25 is arranged on the inner surface of the cooling chamber 4. Since the other parts are the same as those of the previous embodiment, the same members are designated by the same reference numerals and the description thereof will be omitted. The same applies to the following examples.

FIG. 9 shows another embodiment of the drainage receiver 40. In this embodiment, the water collecting frame 45 that constitutes the drainage receiver 40 is omitted, and the joint wall 70 that is inserted into the joint groove 36 of the unit frame body 33 extends upward on the rear wall of the water collecting tray 41. ing. The water collecting wall 42 is welded and fixed near the lower end of the joining wall 70. The joint wall 70 is formed with a flow-down portion 43 composed of a plurality of through-holes provided at regular intervals in the left-right direction, and the through-holes are provided so that a part thereof faces the upper surface of the water collecting wall 42. Has been. Since the water collecting wall 42 is welded and fixed to the joint wall 70, the supporting wall 48 of the drainage receiving main body 44 is also omitted. As described above, the drainage receiver 40 does not need to be composed of the drainage receiver main body 44 and the water collecting frame 45, and the structure of the drainage receiver 40 can be simplified accordingly and the manufacturing cost can be reduced.

FIG. 10 shows another embodiment of the seal structure of the joint portion. The seal body 38 in the seal structure of the present embodiment covers the back surface of the unit frame body 33 and the silicon caulking 74 that seals the gap between the inner box end frame 30 and the upper edge of the frame body 34 on the outer surface of the case body 1. The upper and lower edges of the inner box body 30 and the joint wall 58 are made of a waterproof tape 75 made of butyl rubber. As described above, when the sealing body 38 is composed of the silicone caulking 74 and the waterproof tape 75, the gap between the inner box end frame 30 and the upper edge of the frame body 34, which is most likely to allow dew condensation water to enter, is doubly sealed. By further enhancing the sealing function, it is possible to prevent dew condensation water from entering the filling space as much as possible. The gap between the inner box end frame 30 and the upper edge of the frame body 34 may be sealed with silicon caulking.

As described above, according to the quick cooling box of each of the above-described embodiments, the drainage receiver 40 receives the dew condensation water that drops from the door 2, and the water collection wall that receives the dew condensation water that has entered the filling space. 42 and the lower part 43 for allowing the condensed water received by the water collecting wall 42 to flow down to the water collecting tray 41, the condensed water entering the filling space is received by the water collecting wall 42. Since the water can be made to flow down to the water collecting tray 41 via the lower flow portion 43, not only the condensed water dropped from the door 2 but also the condensed water having entered the filling space can be received by the water collecting tray 41. As described above, even when the sealing structure of the joint portion of the outer box 23, the inner box 24, and the decorative frame 25 cannot exert a sufficient sealing function, the condensed water that has infiltrated into the space filled with the heat insulating material 26 can collect the dew water 41. It is possible to sanitize the inside of the storage by draining the water to the inside of the storage, and to prevent the dew condensation water from leaking to the floor surface.

In each of the above-described embodiments, the embodiment in which the present invention is applied to the quick cooling cabinet is shown, but the present invention can also be applied to the rapid cooling cabinet having the automatic cleaning function. In this case, in addition to the dew condensation water generated at the door 2, the cleaning water attached to the door 2 can be received by the drainage receiver 40.
