7, 39, 41, and 43 are almost the same shape as the ice making water supply tank 31, and are thereby defined in a slightly larger cubic shape.

The partition wall 3 has a connecting pipe 4 as a pipe connecting portion.
5 is buried, and the connection pipe 45 is
And constitutes a water intake port 47 for ice making.

The ice making water supply tank 31 has a dip pipe 51 extending vertically in the tank and having an ice making water intake end 49 at a lower end located near the bottom of the tank, and a dip pipe 51 connected to the upper end of the dip pipe 51 for horizontal orientation. A connection pipe 53 extending from the connection pipe 53 is provided, and an ice-making water take-out port 55 is formed at an end of the connection pipe 53.

When the ice making water supply tank 31 is dropped into the box-shaped recess 33, the ice making water supply tank 31 is positioned in the height direction by the bottom surface portion 35, and the ice making water supply port 55 is positioned in the height direction. , 43 are aligned in the right and left direction by the ice making water intake port 47 so as to face the same, and the ice making water supply tank 31 or the connection pipe 53 is pushed toward the side wall 37 to connect the connection pipe 53 to the connection pipe 53. The ice making water take-out port 55 and the ice making water take-in port 47 are connected to each other.

The connecting pipe 45 or the connecting pipe 45 and the connecting pipe 53 are made of an elastic material such as rubber, and an annular fin portion 57 having a non-reverse cross section and also serving as a stopper is formed on the inner peripheral surface of the connecting pipe 45. Further, an annular land portion 59 having a check cross section is formed on the outer peripheral surface of the connection pipe 53. The annular fin portion 57 and the annular land portion are formed by inserting the connection pipe 53 into the connection pipe 45. 59 and 59 are non-reversely engaged with each other, and at the same time, the liquid-tight sealing of the port connection portion is performed.

As described above, in this refrigerator, the refrigerator 5
Water supply tank 31 in a box-shaped recess 33 formed on the floor
The water supply tank 31 does not reduce the food storage volume of the refrigeration room 5 because the water is stored in the refrigeration room 5 after being dropped. In particular, in the illustrated example, the box-shaped recess 33 has a size that can accommodate the entire water supply tank, and the connection between the ice making water take-out port 55 and the ice making water intake port 47 is also located in the box-shaped recess 33. Water tank 31
However, the food storage volume of the refrigerator compartment 5 is not reduced at all.
