2. Description of the Related Art FIG. 5 shows an example of a conventional commercial refrigerator.
There is a stand-type commercial refrigerator in which a plurality of legs 1 as described above are provided on the bottom surface of the refrigerator main body 2. A plurality of doors 3 are attached to an opening (not shown) of a storage room surrounded by a heat insulating wall of such a commercial refrigerator, and a cooling cycle is provided in a machine room 4 on the side of the refrigerator body 2. A compressor and a condenser (not shown) to be formed are arranged.

As shown in FIG. 6 which is a sectional view taken along the line AA of the commercial refrigerator, a cooling chamber 7 partitioned by a partition wall 6 is provided on the machine room 4 side of the storage chamber 5. Inside the cooling chamber 7, a cooler 7a and a cold air circulation fan 7b are arranged. Then, the cool air from the cooling chamber 7 is circulated in the storage chamber 5 by the cold air circulation fan 7b to store the products stored in the storage chamber 5. Then, in order to efficiently cool the storage chamber 5, defrosting of the cooler 7a is performed at regular intervals by the cooling cycle.

By the way, in the commercial refrigerator, after defrosting, the drain generated by this defrost is discharged to the outside by the drain pan 8, and the joint 9, the drain hose 10 and the drainage connected to the drain pan 8 are drained. It was led to the drainage pit 12 via the hose 11.

A drain hole 13 is formed in the heat insulating wall 5a at the bottom of the storage chamber 5 for discharging cleaning drainage generated when the storage chamber 5 is cleaned to the outside. Then, the cleaning drainage was guided to the drainage pit 12 via the T-joint 14 fitted in the drainage hole 13 and the drainage hose 11 connected to the T-joint 14.

On the other hand, as another example of the conventional commercial refrigerator, as shown in FIG. 7, it is called a Masonry specification in which the refrigerator body 2 is directly mounted on the base 15 which is normally made of concrete without the legs 1 being provided. There is a commercial refrigerator.
In this type of commercial refrigerator, the drain is discharged from the drain discharge 16 formed in advance on the base 15, and the cleaning drain is discharged from the cleaning drain discharge 17. In addition, in order to prevent invasion of mice and the like, these discharge squirrels 16 and 17 are provided with a not-shown ordinary lattice-like member as a lid.

[0007]

However, in the conventional commercial refrigerator having a stand leg, since the drain hose 10 is projected outside the refrigerator, the forklift claw is caught on the drain hose 10 when handling the load, When cleaning, the mop for cleaning may be caught on the drain hose 10, which causes the drain hose 10 to come off the joint 9 and cause water leakage. There is also a problem that a cap for closing the drain hole 13 is required so as not to let the cool air in the storage chamber 5 escape.

On the other hand, in the Masonry-type commercial refrigerator, the refrigerator main body 2 is arranged so that the drain pan 8 and the drain hole 13 are located above the drain discharge 16 and the cleaning drainage discharge 17 formed in advance on the base 15. It has to be installed, and there is a problem that the setting position of the refrigerator main body 2 is limited.

It is an object of the present invention to provide a commercial refrigerator in which a drain hose is arranged in a storage chamber and drain and drainage for cleaning can be discharged through only one discharge hole.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side sectional view of a Masonry-type commercial refrigerator according to an embodiment of the present invention. In the figure, the same reference numerals as those in FIG. 7 indicate the same or corresponding portions.

In the figure, reference numeral 18 denotes an indoor drain hose arranged along the bottom surface of the storage chamber 5. The indoor drain hose 18 has a first L-type connected to a drain pan 8 at an end portion on the cooling chamber 7 side. The joint 19 is connected.

Further, one end of a second L-shaped joint 20 made of hard resin is joined to the end of the indoor drain hose 18 on the drain hole 13 side. Where this second
As shown in FIG. 2, the L-shaped joint 20 has a first coupling portion 20a coupled to the indoor drain hose 18, a second coupling portion 20b fitted in the drain hole 13, and a main body 20c.

The outer diameter of the connecting portion 20b is connected to a drain socket, which will be described later, screwed into the drain hole 13, and the connecting portion 2b.
The second coupling portion 20b is formed to be larger than the inner diameter of the drain socket so that the second coupling portion 20b is hard to come out of the drain socket when the 0b is fitted therein. Thus, for example, it is formed in a notched shape in a semi-cylindrical shape.

Next, the drainage operation of the Masonry-type commercial refrigerator having the L-shaped joint thus constructed will be described.

In the Masonry commercial refrigerator, when the cooling cycle is used to defrost the cooler 7a, the drain from the cooler 7a is drained by the drain pan 8, the first L-shaped joint 19 and the drain pan 8 shown in FIG. It flows into the second L-shaped joint 20 via the indoor drain hose 18. here,
The second coupling portion 20b of the second L-shaped joint 20 is fitted in the drain socket 21 screwed into the drain hole 13, as shown in FIG.

At this time, since the outer diameter D1 of the second connecting portion 20b of the second L-shaped joint 20 is larger than the inner diameter D2 of the drain socket 21, the second socket 20b is firmly fitted and is hard to come off. The second connecting portion 20b is not completely fitted into the drain socket 21, so that the second connecting portion 20b
