Abstract
In an entrance refrigerator, a printed circuit board (PCB) on which heat generating components are mounted is disposed inside a housing such that air used to cool a heat sink of a cold air supply device cools the PCB, thereby preventing overheating of the PCB.
Claims17
An entrance refrigerator, comprising:
- a cabinet configured to extend through a door or a wall, the cabinet including a storage compartment therein for storing goods;
- a housing located at a lower side of the cabinet;
- an outdoor side door coupled to an outdoor portion of the cabinet to open or close the storage compartment;
- an indoor side door coupled to an indoor portion of the cabinet to open or close the storage compartment;
- a cold air supplier configured to supply cold air to the storage compartment, at least a portion of the cold air supplier being located in a space defined by the housing and the lower side of the cabinet;
- a printed circuit board (PCB) on which electrical components are mounted;
- and
- a controller provided on the PCB to control operating of the cold air supply device,
- wherein the housing includes:
- a bottom portion having a suction port through which air is introduced into the housing;
- a front portion extending upward from a front end of the bottom portion;
- a rear portion extending upward from a rear end of the bottom portion;
- a left portion extending upward from a left end of the bottom portion;
- a right portion extending upward from a right end of the bottom portion;
- and
- a discharge port through which the air introduced through the suction port is discharged from the housing,
- wherein the entrance refrigerator further comprises a flow guide plate located within the housing and adjacent to the suction port, to provide an air flow passage within the housing between the suction port and the discharge port, and
- wherein the PCB is disposed within the air flow passage.
