[Prior Art]

 Even in a freezer / refrigerator where the evaporator of the refrigerator is installed in the storage room, or indirectly chill the storage room by circulating cold air in the space between the heat-insulating outer box and the heat-conducting inner box. In any of the cooling storages that are designed to operate, the evaporator must be defrosted in all cases, and the moisture that comes out of the stored products and the moisture in the outside air that enters when the door is opened and closed, etc. It is necessary to melt and discharge it because it will frost. Therefore, this type of storage is provided with a drainage device. Such drainage devices are disclosed, for example, in Japanese Utility Model Publication Nos. 1-123183, 61-116992, 49-45515, 54-33742. A typical example of these conventional drainage devices is schematically shown in FIG. As shown in (a) of FIG. 4, a hole is formed in the bottom wall 51 of the storage chamber, and a water pipe 52 is attached to the bottom wall 51 from below by a flange 53 so as to close the hole. It is mounted watertight. Further, a drain 54 of the bottom wall 51 is covered with a lid 54 made of rubber or the like in order to prevent solid matters from flowing into the water distribution pipe 52. On the other hand, the drainage device shown in (b) is provided with a soft drainage hose 55 for guiding the drainage from another device, for example, the evaporator, and the end of this hose 55 faces the vicinity of the drainage port 56. ..

[0003]

[Problems to be solved by the device]

 Since the drainage device 50 shown in FIG. 4 (a) is also provided with the lid 54, foreign matter does not accidentally flow into the water distribution pipe 52 and the water distribution pipe 52 is not clogged. It is also possible to remove the lid 54 and drain it. However, when draining water, it is troublesome that a person has to remove the lid 54 by hand each time, and there is also a problem that the hand becomes dirty with the drainage. In addition, it cannot be drained all the time, which makes the storage room unsanitary. On the other hand, the drainage device 50 shown in (b) does not have a lid, so it has the advantage that it can be drained at all times without soiling the hands, but there is a risk that debris such as green vegetables will get stuck in the water distribution pipe 52. .. Although the tip of the drain hose 55 faces the drain outlet 56, the tip of the hose 55 is not fixed, so its position is not fixed and the drainage is not reliably guided to the drain outlet 56. There is also the problem of soiling the area around 56. Therefore, the present invention can always drain water without clogging the hands and without clogging, and even if the drainage hose is provided, the drainage near the drainage port is not polluted by the drainage from the drainage hose. The purpose is to provide a device.

【Example】

 Hereinafter, an example in which the present invention is implemented in a double-box structure cold storage will be described. Referring to FIG. 1, the cooling storage 1 according to the present embodiment is roughly configured by an upper storage chamber U, a lower storage chamber D, and a refrigerating device R that cools these storage chambers U and D. It is easy to understand. It can also be seen at a glance that the drainage devices 30 and 30 'are provided on the bottom walls 7a and 8a on the inner sides of the storage chambers U and D. The heat insulating box H surrounding the upper and lower storage chambers U and D has an outer box 2 having a rectangular opening on the front side and a rectangular opening on the front side like the outer box 2. However, it is composed of an inner box 3 smaller than the outer box 2 and a heat insulating material 4 such as urethane foam filled between the inner and outer boxes 2 and 3. Inside the heat-insulating box H, the inner box 3 and cooling air passages 5 and 6 are formed at a predetermined interval so that the upper and lower storage boxes are made of, for example, a non-rust steel plate having good heat conductivity. 7 and 8 are arranged. A partition plate 9 is interposed between the upper and lower storage boxes 7 and 8, and the cooling air bypasses the partition plate 9 as indicated by the arrow. Dew trays 10 and 10 'are provided on the ceilings of the upper and lower storage chambers U and D, and the dew that condenses on the ceilings of the upper and lower storage boxes 7 and 8 is directed to the rear wall side by these dew trays 10 and 10'. It is supposed to be done. In particular, the dew condensation water of the dew tray 10 is shown to be received by the drainage receiver 11 and guided to the drainage device 30 by the drainage hose P.

The refrigeration apparatus R includes a compressor 21 mounted on the upper heat insulating material 20, a condenser 22 similarly mounted on the heat insulating material 20, a fan 23 for blowing air to the condenser 22, an upper heat insulating material. It is composed of an evaporator 24 and the like arranged in a space between 20 and the ceiling of the upper storage box 7. The air cooled by the evaporator 24 is blown into the cooling air passage 5 by the blower 25, bypasses the partition plate 9 from the cooling air passage 5 to reach the cooling air passage 6, and the upper and lower storage boxes 7, The cooling air passage on the outer side of the side wall of 8 is moved up and returned to the blower 25. In this way, the cooling air is circulated so that the upper and lower storage boxes 7 and 8 are indirectly cooled. A second dew tray 26 is provided below the evaporator 24, and the condensed water received by the dew tray 26 is arranged in the heat insulating material 4 although not shown in the drawing. It is designed to be drained to the outside of the refrigerator through the pipe.

As shown in FIG. 1, the drainage device 30 is provided, for example, at the center of the bottom wall 7 a of the upper storage box 7, and the drainage device 30 ′ is the bottom wall of the lower storage box 8. 8a is provided at a position vertically aligned with the drainage device 30. A first embodiment of the drainage device 30 is shown in FIG. The drainage port 31 of the drainage device 30 is formed as a substantially rectangular opening. That is, the rear wall 7b of the upper storage box 7 is obtusely angled, and the bottom wall 7a is bent downward at a substantially right angle so as to have a step, and is perforated so as to have the inclined receiving portion 32 and the horizontal receiving portion 33. ing. The drain pipe 34, which is attached to the drain port 31 from above, is integrally formed of, for example, synthetic resin from a flange portion F having a diameter larger than that of the drain outlet 31 and a pipe portion 36 having a diameter smaller than the flange portion F. There is. As shown in (a) of FIG. 2, the flange portion F includes a horizontal flange portion 35 which comes into contact with the horizontal receiving portion 33 of the bottom wall 7a when mounted and an inclined flange portion which comes into contact with the inclined receiving portion 32 of the rear wall 7b. And a section 36. As shown in FIG. 2A, the horizontal flange portion 35 has a semi-doughnut shape in a plan view, and the inclined flange portion 36 has a predetermined length. The flange portions 35 and 36 are integrally formed in a substantially donut shape. Therefore, the flange portion F 1 is in watertight contact with the bottom wall 7a and the rear wall 7b of the upper storage box 7 of the drainage port 31. A reduced diameter portion 39 is formed below the pipe portion 36, and a drainage hose, for example, is connected to the reduced diameter portion 39.

A plurality of ribs 40 a to 40 f are formed in the upper portion of the drain pipe 34, for example, integrally with the drain pipe 34 at substantially equal intervals. That is, the ribs 40a to 40d are integrally formed so as to rise from the horizontal flange portion 35 and the ribs 40e and f from the inclined flange portion 36. The ribs 40a to 40f extend in both directions above and below the flange portion F, and the surfaces thereof are arranged vertically and radially, and there is a predetermined space between the facing inner edges 43, 43. That is, at the center of the drainage port 31, there is a cylindrical space without the ribs 40a to 40f. The diameter of this cylindrical space is substantially equal to the outer diameter of the drainage hose P. Further, a step is formed below the inner edges 43 of the ribs 40a to 40f, and the cylindrical space is narrowed. As shown in FIG. 1, the drainage device 30 'provided on the bottom wall 8a of the lower storage box 8 has substantially the same structure as that of the above-described embodiment or the embodiment described later.

Next, the operation of the above embodiment will be described. The drainage pipe 34 is inserted into the drainage port 31 from above the bottom wall 7a with the reduced diameter portion 39 first. Then, the flange portion F of the drainage pipe 34 is attached in close contact with the drainage port 31. When the drain hose P is provided, the tip of the drain hose P is inserted and locked in the cylindrical space. For example, food items are put in the upper storage box 7 and used in the conventional manner. If dew water or the like is generated during use, the ribs 40a to 40f are formed at substantially equal intervals, so that there is a gap between them and the ribs 40a to 40f are constantly drained without the need to bother with a conventional lid. Further, since the ribs 40a to 40f extend above the flange portion 35, that is, project above the bottom wall 7a, the ribs 40a to 40f flow into the drain pipe 34 even if debris such as green vegetables is mixed in the drainage. There is no such thing. Further, since the tip of the drain hose P is locked in the tubular space formed by the inner edges 43, 43 of the ribs 40a to 40f, the drainage from the drain hose P is reliably guided to the drain pipe 34. It

As seen in a conventional refrigerator or the like, there are storage boxes on the upper and lower sides, an upper storage box is provided with a drainage device at the back, and a lower storage box is provided on the front side. When the refrigerator body is tilted forward, the rear drainage device does not function, and when it is tilted backward, it is difficult to drain water from the front drainage device. However, according to this embodiment, it is shown in FIG. As described above, since the drainage devices 30 and 30 'are provided behind the upper and lower storage boxes 7 and 8, if the refrigerator 1 is installed rearward with an inclination of, for example, 1 to 2 degrees, the upper and lower storage boxes 7 and 8 are simultaneously removed.

A second embodiment of the present invention will be described with reference to FIG. According to this embodiment, a ring body 41 larger than the diameter of the drainage hose P to be applied is provided above the ribs 40e and 40f located on the rear wall 7b side. The other parts have substantially the same structure as the above-mentioned embodiment, and therefore, the same reference numerals are given and the duplicated description will not be given. According to this embodiment, since the ring body 41 is formed above the ribs 40e and 40f, the tip of the drainage hose P can be inserted into the ring body 41, and the drainage hose P can be secured more reliably. The effect that can be maintained is obtained. Also, the insertion depth can be adjusted to accommodate the length of the drain hose P. Although not shown in the figure, if the distance between a pair of opposing ribs is made smaller than the distance between other ribs and the drain hose P is sandwiched between the opposing ribs having a small gap, the drain hose P The effect that can absorb the bending of
