Therefore, drainage generated when defrosting the inside of the refrigerator or cleaning the inside of the refrigerator is collected in the drainage port 5 at the bottom of the refrigerator main body 1 and stored in the annular recess 10 in the stored water 14. When the lower end of the cylindrical peripheral wall 13 of the cap 6 is immersed and the stored water level exceeds the height of the cylindrical wall portion 9, the small projection 11 causes a gap between the back surface of the cap 6 and the top surface of the cylindrical wall portion 9. The stored water 14 flows into the tubular wall portion 9 through the gap 15 formed in
Although it is discharged to the outside of the refrigerator through the drainage channel 8 below, since the lower end of the cap cylindrical peripheral wall 13 is immersed in the stored water 14, the inside and the outside of the refrigerator are drained by the cap 6 and the stored water 14. The mouth 5 is airtightly blocked, so that cold air in the refrigerator is prevented from flowing out of the drainage outlet 5 and external air is prevented from flowing into the refrigerator through the drainage outlet 5.

However, when the opening / closing door of the cabinet main body 1 whose inside is kept airtight is suddenly opened, the inside of the cabinet main body 1 momentarily becomes negative pressure, so that the cap 6 in the drainage port 5 is drained. When the inside air is pushed up and the open / close door of the storage body 1 is closed, the warm outside air flowing into the storage body 1 is cooled and contracted by the cold air inside the storage body 1, so that the inside of the storage compartment becomes negative. When the pressure is applied, the cap 6 in the drainage port 5 is also pushed up by the outside air in the drainage channel 8, and in any case, the cap 6 is largely lifted up, and the lower end of the cylindrical peripheral wall 13 is higher than the stored water 14. As a result, the cap 6 and the stored water 14 do not fulfill the trap function, and as a result, the outside air flows into the cabinet body 1 from the drainage channel 8,
Outside odors may enter the cabinet body 1 or cause frost or ice to build up in the cabinet, and when the outside air suddenly flows into the cabinet from the drainage channel 8 as described above. In this case, there is a possibility that dust and the like adhering to the drainage channel 8 may be blown off and scattered into the storage, which is not preferable for hygiene.

Also, in the drain trap disclosed in Japanese Utility Model Laid-Open No. 63-40783, a plurality of protrusions extending inward in the radial direction are formed on the inner surface of the bell-shaped upper lid, and the upper lid is lowered into the drain outlet. The upper lid is prevented from being lifted up by rotating and inserting and fitting the protrusion into the L-shaped groove of the drainage pipe. However, if external shocks from inside and outside the store, such as negative pressure in the store, wind pressure from the drain pipe, and large amount of drainage from the store, are applied to the top over a long period of time, the rotating position of the top gradually changes. There is a possibility that the protrusions of the upper lid may move to the vertical groove portion of the drain pipe L-shaped groove due to misalignment, and at this time, due to the external impact, the protrusions are guided by the vertical groove portion of the drain pipe and largely lifted, and the upper lid is drained. There is a risk that it will come off and lose the trap function,
In addition to the same problems as in the conventional device, the inner surface of the upper lid above the protrusion and the lateral groove of the drain pipe L-shaped groove are both undercuts in the mold structure. There is a problem that the cost of the mold is significantly increased because the work is complicated, such as sliding it to separate it from the part, or constructing the mold in a split mold.
