The partition wall 33 is composed of a heat insulating material 32, an inner box 47 that covers the cooling space side of the heat insulating material, and an outer box 48 that covers the condensation space side that is the outer surface of the heat insulating material 32. 49 is the vertical wall 33 of the partition wall 33
This is a protrusion formed at the lower part of A, located below the suction port 15 and extending toward the storage chamber. It is in contact with the plate 11.
Note that a predetermined gap is formed between the machine room side end of the suction port 15 and the vertical wall 33A. Also, 50
is a recess formed in the center of the protrusion 49. For example, when the evaporator 37 is defrosted, dew drips from the drainage opening 43C' and the dew that travels through the inner box 47 passes through the recess 50 between the protrusion 49 and the bottom plate of the machine room. Space 5 formed between 31
Drip into 2.

53 is a storage chamber bottom plate that covers the upper surface of the base 4;
For example, the transparent door 8 of the storage room 2 is sloped low toward the machine room 3 to catch dew adhering to the inner surface thereof. The machine room side edge of the storage room bottom plate extends outward from the partition plate 11, and forms an extension portion 53A that extends into the drainage space 52 of the machine room 3 when the storage room 2 and the machine room 3 are connected. is formed. 53A' is the extension part 53
A recess 50 is formed in the recess 50 to receive dew dripping from the recess 50 formed in the protrusion 49.
It is formed directly below. 54 is a drainage port formed at the lowest part of the recess 53A', that is, the lowest part of the storage chamber bottom plate 53;
A guide that extends upward from the machine room side end of A′.
The upper end of this guide is located closer to the machine room than the recess 50.

The upper surface of the inner box lower wall plate 47C that covers the protruding lower wall 49C of the partition wall 33 extends vertically upward from the lower end of the vertical wall 33A while covering the space 52 side, and touches the tip of the inner box lower wall plate 47C. The outer box tip 48A, which is bent at right angles toward the adjacent storage chamber, is in close contact with the outer box.

Reference numeral 56 denotes an opening formed in the machine room bottom plate 31 directly below the drain port 54, and its diameter is formed to be slightly larger than the diameter of the drain port 54. Further, 57 is a drain tank provided in a space below the machine room bottom plate 31 to engage with rails 58 and 59 having an L-shaped cross section and to be slidable in the front and rear direction. When the drain tank 57 is stored, a drainage receiving port 57'A is formed which is located directly below the opening 56 and has a larger diameter than the opening 56.

The storage room 2 and the machine room 3 are connected to the bottom plate 60 of the base 4.
Bolts 6 are attached to the base reinforcing material 61 and the machine room bottom plate 31.
2 are connected to each other, and a screw 64 is connected to the connecting member 63 attached to the partition wall 33 and the upper frame 6 of the storage chamber 2, and the connection is made by tightening each. Here, at the same time as connecting the storage chamber 2 and the machine room 3, the extension part 53A of the storage chamber bottom plate 53 is located below the recess 50 formed in the protrusion 49, and the opening 56 of the machine room bottom plate 31 and , the drain port 57'A of the drain tank 57 is located directly below the drain port 54 formed in the extension portion 53A.

Therefore, as shown by the dashed-dotted arrow in FIG.
On the other hand, dew that drips from the evaporator 37 during defrosting passes through the recess 50 of the protrusion 49 and drips into the extension 53A, leading to the storage chamber 2 and the evaporator 3.
The dew from 7 is collected in the extension part 53A, passes through the drain port 54, the opening 56, the drain receiving port 57'A,
Since the water is dripped into the drain tank 57, dew processing can be performed all at once. Also, the lower wall plate 4 of the protrusion 49
The upper surface of 7C is in close contact with the outer box 48, which extends from below and is bent, and the tip of the lower wall plate 47C is in contact with the outer box 18, so that the dew that travels through the lower wall plate 47C will not touch the surface of the outer box 48. The water is transmitted and falls downward, and drips from the opening 56 into the drain tank 57. Therefore, dew is prevented from penetrating into the heat insulating material 32 from the tip of the lower wall board 47C, and deterioration of the heat insulating material 32 can be prevented. Furthermore, since there is no need to connect a drain pipe or the like, the drainage device can be extremely simplified.

As described above, the present invention includes a partition wall that is disposed in a machine room to form a cooling space that accommodates an evaporator and a blower together with the partition plate, and a protrusion that is formed at the bottom of the partition wall and contacts the partition plate. a drainage space formed below the protrusion; a recess formed in the protrusion that communicates the cooling space and the drainage space; and a recess arranged at a low slope toward the machine room. a bottom plate of the storage room, an extending part formed at the lowest part of one end of the bottom plate and extending to the drainage space passing below the partition plate, a drainage port formed in the extension part, and a drain opening formed in the extension part; It is formed in the bottom plate of the machine room that covers the lower surface, and consists of an opening located directly below the drain port, and a drain tank equipped with a drainage receiving port located directly below this opening.
Since the dew generated in the storage room and cooling space collects in the extension and flows into the drain tank, dew can be treated all at once and quickly. Since the extension part is disposed at the drain port and the drain tank is disposed below the drain port of the extension part, the structure of the drainage device can be simplified and the assembly work thereof can be facilitated.
