<Operation of refrigerator 100>
When the refrigerator 100 performs the cooling operation, the temperature of the compressor 11 and the like rises. In order to suppress these temperature rises, the blower fan 12 rotates in the machine room 10 to generate an air current. The airflow generated by the rotation of the blower fan 12 is branched into two airflows on the compressor 11 side and the air passage 30 side by the airflow branching portion 31 a in the machine room 10. Since the air passage 30 is formed closer to the blower fan 12 than the compressor 11, the air flow branched into the air passage 30 at the air flow branching portion 31a has momentum. The airflow branched into the air passage 30 is vigorously transmitted through the air passage 30 as shown by the arrows in FIG.

  The airflow supplied from the air passage 30 to the inside of the foot cover 20 strikes the side wall portion 23 on the front surface of the foot cover 20 from the air passage outlet portion 30b at the center of the refrigerator body 1. Since the airflow hitting the side wall portion 23 hits the central portion in the left-right direction of the side wall portion 23 of the foot cover 20, the airflow is almost equally branched in the left-right direction. The branched airflow hits the liquid B accumulated in the liquid reservoir 22 and promotes evaporation.

  The air flow that has promoted the evaporation of the liquid flows through the liquid reservoir 22 to the outer sides in the left-right direction, flows through the two grooves 28a and 29a, and is discharged from the two exhaust ports 20b.

  Here, the liquid B collected in the liquid reservoir portion 22 of the foot cover 20 is easily liquid even if the liquid is accumulated in the liquid reservoir portion 22 due to the presence of the side wall portions 24 and 25 that are inclined upward from the inside toward the outside. There will be no spills.

  On the other hand, since the bottom surface portion 27 of the liquid reservoir portion 22 of the foot cover 20 is provided with a plurality of convex portions 27a, the surface area of the bottom surface portion 27 of the liquid reservoir portion 22 increases, and the stored liquid and air Vaporization can be promoted by increasing the contact of.

  As described above, when there is condensation on the lower end portion of the freezer compartment door 3 and the gasket 3a, or when there is dripping of food, drinks, etc. from the inside of the refrigerator main body 1, condensation water or dripping has occurred. The liquid is received by the foot cover 20 and stored in the liquid reservoir 22. The airflow of the blower fan 12 in the machine room 10 is supplied to the inside of the foot cover 20 through the air passage 30. The liquid accumulated in the liquid reservoir 22 is evaporated more quickly by this air flow. Thereby, the liquid in the liquid reservoir 22 does not remain for a long time. The liquid does not drip beyond the capacity of the liquid reservoir 22, and the floor on which the refrigerator 100 is installed does not get wet. Further, dust does not accumulate in the liquid reservoir 22, and the liquid reservoir 22 is not soiled.

<Effect of Embodiment 1>
According to the first embodiment, the refrigerator 100 includes the blower fan 12 disposed in the machine room 10 in the lower rear portion of the refrigerator body 1.

The refrigerator 100 is provided in the refrigerator main body 1 and includes an air passage 30 communicated between the machine room 10 and the inside of the foot cover 20.

  According to this configuration, the airflow of the blower fan 12 disposed in the machine room 10 can be supplied to the inside of the foot cover 20 having the liquid reservoir 22. Therefore, the liquid accumulated in the liquid reservoir 22 can be forcibly and quickly evaporated, and the liquid does not exceed the capacity of the liquid reservoir 22. Thereby, the liquid in the liquid reservoir 22 does not remain for a long time. The liquid does not drip beyond the capacity of the liquid reservoir 22, and the floor on which the refrigerator 100 is installed does not get wet. Further, dust does not accumulate in the liquid reservoir 22, and the liquid reservoir 22 is not soiled.
