The freezer compartment 2 is arranged on the upper stage of the inner box 12, and the refrigerator compartment 3 is arranged on the lower stage.

  A machine room 14 is provided in the lower part of the refrigerator body 11. The machine room 14 is arranged outside the heat insulating box 15 and includes a compressor 40. A refrigeration cycle including a compressor 40 and a heat exchanger (not shown) generates cold air and distributes the cold air to the freezer compartment 2 and the refrigerator compartment 3 through a duct (not shown). Thereby, the refrigeration temperature or freezing temperature required in each chamber is obtained.

  A compressor substrate 20 that supports the compressor 40 is disposed at the bottom of the refrigerator body 11. Legs 33 b are provided at the rear of the compressor substrate 20. In addition, the leg part 33b may provide a wheel in order to move the refrigerator 1 easily.

  FIG. 3 is an enlarged side sectional view showing the bottom of the refrigerator 1. The refrigerator compartment 3 is provided with a door 23. The door 23 is rotatably attached to the right side (X1 direction) of the opening of the refrigerator compartment 3 by a pivot part 23a. A gasket 23b is provided on the back surface of the door 23 along the peripheral portion. A magnetic material is provided inside the gasket 23b. Thereby, the back surface of the door 23 is pressure-bonded to the front surface of the inner box 12 via the gasket 23b. The freezer compartment 2 is similarly provided with a door 22.

  A weight 50 made of metal is provided inside the heat insulating foam (not shown) between the inner box 12 and the outer box 13. The weight 50 is disposed on the opposite side (X2 side) to the side (X1 direction) on which the pivotal support portion 23a that pivotally supports the door 23 is provided in the left-right direction, and on the rear side (Y2 side) of the refrigerator main body 1. . Similarly, the compressor 40 is also arranged on the opposite side (X2 side) from the pivotal support 23a in the left-right direction.

A bracket 32 protruding forward is attached to the front bottom of the refrigerator main body 11. The bracket 32 is provided with a columnar pivot 23a of the door 23 so as to protrude upward. A bolt 34 is screwed and fixed behind the pivotal support 23a of the bracket 32.

  A screw hole 33c of the leg portion 33a is screwed into the bolt 34, and the leg portion 33a is rotatably arranged. The height can be adjusted by rotating the leg 33a. Since the bolt 34 is disposed in front of the front surface of the refrigerator main body 11, the leg portion 33 a protrudes from the front surface of the refrigerator main body 11.

  Further, the distance from the rotation shaft 34a of the leg portion 33a to the outer peripheral surface varies depending on the position in the circumferential direction in the range from the minimum distance R1 to the maximum distance R2. Thereby, the leg part 33a can be protruded from the side surface of the refrigerator main body 11 according to a rotation position, and the protrusion amount can be varied.

  At this time, as shown by a solid line in FIG. 6, the leg portion 33 a is arranged behind the front surface of the door 23 when the direction of the maximum distance R2 is directed forward (Y1 direction). That is, the leg 33a does not protrude from the front surface of the door 23 even if the rotational position is changed. Thereby, the leg part 33a hides in the lower part of the door 23 with respect to the line of sight from a user's upper direction, and the beauty | look of the refrigerator 1 improves. Moreover, there is no possibility that the user may get caught in the leg 33a on the front side of the refrigerator 1.

  Further, as shown by a one-dot chain line in FIG. 6, when the direction of the maximum distance R2 is directed to the right (X1 direction), the protruding amount of the leg portion 33a from the side surface of the refrigerator main body 11 is lower than the lower limit value of the heat radiation space S.

When the direction of the maximum distance R2 is directed forward (Y1 direction), the protruding amount of the leg portion 33a is smaller than the gap C between the packaging box 61 and the refrigerator main body 11. Since the refrigerator 1 rattles in the packaging box 61 during transportation or the like, the refrigerator 1 is accommodated in the packaging box 61 via the buffer material 63. Moreover, the clearance gap C is provided between the side surface of the refrigerator main body 11, and the packaging box 61, and the refrigerator 1 and the packaging box 61 are prevented from being rubbed and damaged. By making the protrusion amount of the leg portion 33a smaller than the gap C (for example, 10 mm), the leg portion 33a can be prevented from being rubbed and damaged by the packaging box 61.

  According to this embodiment, the installation area at the time of installation of the refrigerator 1 is made small by making the protrusion amount from the side surface of the refrigerator main body 11 smaller than the lower limit value of the heat radiation space S on the side of the refrigerator main body 11 defined in advance. However, the refrigerator 1 can be installed stably. Moreover, since the leg part 33a is distribute | arranged ahead from the front surface of the refrigerator main body 11, the front-back direction (Y1-Y2 direction) of the refrigerator 1 is stably supported by the leg part 33a.

  Moreover, since the outer peripheral surface of the leg part 33a is arranged behind the front surface of the door 23 (Y2 side), the leg part 33a is hidden under the door 23 with respect to the line of sight from above the user, and the aesthetic appearance of the refrigerator 1 Will improve. Moreover, there is no possibility that the user may get caught in the leg 33a on the front side of the refrigerator 1.

  Moreover, the leg part 33a is screwed with the refrigerator main body 11, and is distribute | arranged so that rotation is possible, and protrusion amount changes according to the rotation position of the leg part 33a. Thereby, the protrusion amount can be changed according to an installation place, and the convenience of the refrigerator 1 can be improved.

  The leg portion 33a is formed of an inclined surface that is inclined inward as the outer peripheral surface is directed upward. Thereby, the lower part of the leg part 33a has a large ground contact surface, and can support the refrigerator main body 11 stably. Further, the upper portion of the leg portion 33a is easily hidden from the line of sight from above the user. Thereby, the beauty | look of the refrigerator 1 improves more.
