Refrigerator with pressure equalization valve
View Patent ↗A refrigerator including a housing with a chassis and a door enclosing a chilled interior; and a pressure equalization valve extending through a wall of the housing thereby facilitating an inflow of air from the surroundings into the interior and thereby blocking an outflow of air from the interior into the surroundings, the refrigerator comprising, a wall having a throughbore formed therein in a parallel flow arrangement with the pressure equalization valve, through which air can pass in two directions, wherein the flow of air is less than that of the airflow through the pressure equalization valve in the throughflow direction and greater than that of the air leakage value of the pressure equalization valve in the blocked direction.
1. A refrigerator comprising a housing with a chassis and a door enclosing a chilled interior; and a pressure equalization valve extending through a wall of the housing thereby facilitating an inflow of air from the surroundings into the interior and thereby blocking an outflow of air from the interior into the surroundings, the refrigerator comprising, a wall having a throughbore formed therein in a parallel flow arrangement with the pressure equalization valve, through which air can pass in two directions, wherein the flow of air is less than that of the airflow through the pressure equalization valve in a throughflow direction and greater than that of the air leakage value of the pressure equalization valve in the blocked direction.
2. The refrigerator according to claim 1 wherein the throughbore extends through the wall on a curved path.
3. The refrigerator according to claim 1 and further comprising a heater in thermal contact with the throughbore.
4. The refrigerator according to claim 3 wherein the heater is disposed on a front side of the chassis and that the throughbore is present in an area of the housing heated by the heater.
5. The refrigerator according to claim 1 and further comprising a sealing member for sealing a gap between door and chassis, wherein the sealing member is anchored in a groove of the door and the throughbore extends between the walls of the groove and an anchorage section of the sealing profile engaged with the groove.
6. The refrigerator according to claim 5 wherein the throughbore includes at least one section extending in the longitudinal direction of the groove.
7. The refrigerator according to claim 5 wherein a channel is formed in sidewalls of the groove and is aligned transverse to the longitudinal direction of the groove.
8. The refrigerator according to claim 5 wherein the groove is divided laterally by a rib in engagement with a longitudinal channel of the sealing member, and that the rib is interrupted locally to form at least a portion of the throughbore.
9. The refrigerator according to claim 5 wherein at least one end of the throughbore is disposed at a corner of the door.
