  • the backflow preventing part 37 is formed of rubber, for example.
  • the material of the backflow preventing part is not limited hereto, and may vary as necessary.
  • the backflow preventing part 37 communicates with the valve body 35 and the open/close member 40 through a upper opening thereof, and thus, the defrost water having passed through the defrost water flowing hole 32 of the valve body 35 and the passing hole 42 of the open/close member 40 is flown.
  • the lower end region of the backflow preventing part 37 comprises a cut part 36 to discharge the defrost water. According to this, the defrost water flown into the backflow preventing part 37 moves downward and is discharged to the water collecting tray 6 through the cut part 36.

  • the defrost water moving along the drain pipe 23 is discharged to the water collecting tray 6 through the drain valve 30.
  • the defrost water flown into the drain valve 30 from the drain pipe 23 passes through the defrost water flowing hole 32 of the valve body 35 and the passing hole 42 of the open/close member 40 and drops to the lower region of the backflow preventing part 37.
  • the cut part 36 of the backflow preventing part 37 is opened by the weight of the defrost water, the defrost water is discharged to the water collecting tray 6 through the open cut part 36.
  • the cut part 36 which was opened by the weight of the defrost water is again closed after the defrost water has been discharged, and thus, air does not flow into the inside of the drain valve 30 through the cut part 36.
  • the air which flows inside the valve body 35 flows into the drain pipe 23 through the passing hole 42 and the defrost water flowing hole 32 of the open/close member 40.
  • the air flown into the drain pipe 23 continuously moves upward and flows inside the refrigerating and freezing compartments 3a and 3b, thereby settling the change in pressure of the storage compartments 3a and 3b.
  • the doors 7a and 7b can be easily opened with a little force.
  • the open/close chamber 40 of the drain valve 30 moves downward by its self weight and is then restored to the closed position as illustrated in FIGS. 4 and 5.

According to this, the drain valve 30 performing two functions of discharging the defrost water and flowing air into the refrigerating and freezing compartments 3a and 3b with a simplified structure is provided.
  • drain valve 30 externally appears slim, it can be easily installed even at a narrow space. Also, since inner diameters of the passing hole 42 and the drain pipe 23 are substantially similar, external air can be promptly flown into the drain pipe 23.
  • the flowing of external air into the storage compartments can be prevented and at the same time the defrost water can be discharged to the outside through the drain valve with a simplified structure when the internal pressure of the storage chambers and external pressure are well balanced. Even when a change occurs in the pressure of the storage compartments generated as the doors are opened and closed, external air can be flown inside the storage compartments so as to facilitate opening of the doors.
