The front opening of the lower freezer compartment 14 is closed by a drawer-type lower freezer compartment door 19 disposed below the ice-making compartment door and the upper freezer compartment door 18.
[0016] On the inner side of the vegetable compartment door 16, the ice-making compartment door, the upper freezer compartment door 18, and the lower freezer compartment door 19, a pair of left and right support frames for holding the storage containers 11a, 13a, and 14a are respectively fixed, and the storage containers 11a, 13a, and 14a are configured to be pulled out of the cabinet together with the door opening operation.
[0017] (2) Fixed feet 20 As shown in FIG. 1, a pair of left and right fixed feet 20 are provided on the rear side of the lower surface 2a of the refrigerator body 2. The fixed feet 20 are composed of columnar wheels disposed between the refrigerator body 2 and the installation surface P, and support the rear part of the refrigerator body 2. The fixed feet 20 cannot adjust the height of the refrigerator body 2.
[0018] (3) Adjusting feet 30 The adjusting feet 30 are provided at the left and right ends of the front part of the lower surface 2a of the refrigerator body 2 respectively. The adjusting feet 30 are disposed between the refrigerator body 2 and the installation surface P and support the front part of the refrigerator body 2, so as to form a space with a certain interval between the refrigerator body 2 and the installation surface P such as the floor together with the fixed feet 20.
[0019] The adjusting feet 30 are provided so that the height can be adjusted by the user. Specifically, the adjusting feet 30 include a connecting portion 31 and a leg portion 32.
[0020] The connecting part 31 is made of, for example, a metal material. The connecting part 31 is fixed to the front part of the lower surface 2a of the refrigerator main body 2 by bolts. In the present embodiment, at the front side of the lower surface 2a of the refrigerator main body 2, both left and right end parts 2a2 are recessed upward from the central part 2a1 in the width direction, and the connecting part 31 is fixed to both the recessed left and right end parts 2a2.
[0021] With the connecting part 31 fixed to the lower surface 2a of the refrigerator main body 2, it extends forward from the front end of the refrigerator main body 2 with a length that does not exceed the front end of the lower freezer door 19. A screw hole 31a that penetrates the connecting part 31 in the thickness direction (vertical direction) is formed in front of the refrigerator main body 2 (see FIGS. 4 and 5).
[0022] The leg part 32 includes a first contact part 33 having a first contact surface 33a that contacts the installation surface P, a second contact part 34 having a second contact surface 34a that contacts the installation surface P, a holding part 36 provided with a recess 35 that opens downward, and a male screw part 37 that is screwed into the screw hole 31a provided in the connecting part 31.
[0023] The first contact part 33 is made of a resin molded body obtained by molding a synthetic resin such as POM (polyacetal resin) into a sphere. The lower part of the first contact part 33 is housed in the recess 35 of the holding part 36 so as to protrude downward from the holding part 36.
[0024] The holding part 36 is made of a resin molded body obtained by molding a synthetic resin such as POM (polyacetal resin) into a predetermined shape. Preferably, the holding part 36 is molded from the same synthetic resin as the synthetic resin constituting the first contact part 33.
[0025] The recess 35 provided in the holding portion 36 has an opening width at the lower end thereof smaller than the diameter of the first contact portion 33. For example, as shown in FIG. 4, the lower end portion of the recess 35 has a shape that tapers downward with the inner diameter decreasing downward, or although not shown, the inner side surface of the lower end portion of the recess 35 has a shape that protrudes from a plurality of directions toward the center, and the opening width at the lower opening portion 35a of the recess 35 is smaller than the diameter of the first contact portion 33. Thereby, the holding portion 36 holds the first contact portion 33 so that the first contact portion 33 accommodated in the recess 35 does not fall out from the lower opening portion 35a.
[0026] A second contact portion 34 is provided outside the holding portion 36. The second contact portion 34 is composed of a ring-shaped member surrounding the outside of the holding portion 36, and includes a cylindrical main body portion 34b extending in the vertical direction along the peripheral surface of the holding portion 36, and a support portion 34c protruding in a flange shape radially outward from the lower end of the cylindrical main body portion 34b.
[0027] The second contact portion 34 is provided so as to be movable in the vertical direction along the outer peripheral surface of the holding portion 36. As shown in FIG. 4, a hole portion 34d into which a claw portion 36a protruding outward from the lower end portion of the outer peripheral surface of the holding portion 36 is fitted is provided in the upper portion of the cylindrical main body portion 34b. Further, a locking recess 34e recessed radially outward is provided at the lower end portion of the inner peripheral surface of the support portion 34c.
[0028] In such a second contact portion 34, when the cylindrical main body portion 34b is moved downward so that the second contact surface 34a provided below the support portion 34c is positioned below the first contact surface 33a of the first contact portion 33, the claw portion 36a protruding from the outer peripheral surface of the holding portion 36 is fitted into the hole portion 34d of the cylindrical main body portion 34b, and the vertical position is fixed. Thereby, the second contact surface 34a comes into contact with the installation surface P and the second contact portion 34 supports the front portion of the refrigerator body 2.
[0029] Also, when the claw portion 36a comes out of the hole portion 34d of the cylindrical main body portion 34b, the second contact portion 34 can be moved so that the second contact surface 34a is positioned above the first contact surface 33a of the first contact portion 33. Then, as shown in FIG. 5, when the second contact portion 34 is moved upward, the claw portion 36a of the holding portion 36 is caught by the locking recess 34e to hold the second contact portion 34.
[0030] As a result, the first contact surface 33a contacts the installation surface P and the first contact portion 33 supports the front portion of the refrigerator body 2. Since the first contact surface 33a is spherical, the refrigerator 1 can be easily moved not only in the front-rear direction but also in the left-right direction.
[0031] A male screw portion 37 protruding upward is provided on the upper surface of the holding portion 36. By rotating the holding portion 36 around the axis of the male screw portion 37, the height of the holding portion 36 with respect to the connecting portion 31 is adjusted, and the heights of the first contact portion 33 and the second contact portion 34 held by the holding portion 36 are adjusted.
[0032] (4) Effect In the refrigerator 1 of the present embodiment as described above, since the first contact surface 33a having a spherical shape contacts the installation surface P and supports the front portion of the refrigerator body 2, the refrigerator 1 can be easily moved not only in the front-rear direction but also in the left-right direction. Also, the installation area between the first contact surface 33a and the installation surface P can be reduced, and damage to the installation surface P can be prevented.
[0033] In the refrigerator 1 of the present embodiment, apart from the first contact portion 33 having the spherical first contact surface 33a, a second contact portion 34 that contacts the installation surface P is provided at a position below the first contact surface 33a. Therefore, by bringing the second contact surface 34a of the second contact portion 34 into contact with the installation surface P, the first contact surface 33a can be separated from the installation surface P, and undesired movement of the refrigerator 1 can be suppressed.
[0034] Furthermore, in the present embodiment, by rotating the holding portion 36 around the axis of the male screw portion 37, the vertical position of the second contact portion 34 with respect to the connecting portion 31 can be adjusted. Therefore, the height and inclination of the refrigerator 1 can be adjusted, and rattling can be suppressed.
[0035] In the present embodiment, since the first contact portion 33 is a sphere, it is easy to ensure the strength required to support the front portion of the refrigerator 1.
[0036] Also, in the present embodiment, since the concave portion 35 of the holding portion 36 has a shape that tapers downward such that the inner diameter becomes smaller toward the bottom, it is possible to prevent the first contact portion 33 accommodated in the concave portion 35 from accidentally falling out from the lower opening portion 35a.
[0037] (5) Modified Example In the above-described embodiment, the first contact portion 33 is a sphere. However, the first contact portion may have a shape in which the shape of the portion located on the opposite side of the installation surface P is different from a spherical surface, such as a shape in which the upper portion of the sphere is chipped.
[0038] For example, as shown in FIGS. 6 and 7, the first contact portion 133 includes a spherical segment portion 133b in which the upper portion of the sphere is chipped, and a columnar portion 133c provided above the spherical segment portion 133b.
[0039] In the first contact portion 133, the columnar portion 133c is housed in the concave portion 35 of the holding portion 36, the spherical segment portion 133b faces downward with a first contact surface 133a forming a spherical surface, and protrudes downward from the lower end of the holding portion 36. A plurality of upwardly protruding ridges (ribs) 133d are provided in a lattice pattern on the upper side of the columnar portion 133c.
[0040] Even in this modified example, similar to the above-described embodiment, since the first contact surface 133a forming a spherical surface contacts the installation surface P to support the front portion of the refrigerator main body 2, the refrigerator 1 can be easily moved in the front-rear and left-right directions, and damage to the installation surface P can be prevented.
[0041] Also, by forming the first contact portion 133 into the above-described shape including the spherical recessed portion 133b and the columnar portion 133c, the height of the first contact portion 133 can be suppressed.
[0042] Further, by providing a plurality of ridges 133d on the upper side of the columnar portion 133c, it is possible to prevent the occurrence of dents on the first contact surface 133a due to sink marks (shrinkage of synthetic resin) that occur after the formation of the first contact portion 133 while ensuring the strength of the first contact portion 133.
