Abstract

A refrigeration and air conditioning device, which is an outdoor unit of a refrigeration and air conditioning device provided with a heat exchanger within a housing (2) and blowers (3) arranged on the housing, the housing (2) being provided with a side cover covering the sides, a base (9) covering the bottom and a foot portion (10) arranged below the base (9), the foot portion (10) being provided with a raised portion (10b) upwardly bending an end face (10c) of a lower surface of the foot portion. The refrigeration and air conditioning device increases rigidity without increasing costs.

First claim

The invention claimed is:

1. A refrigeration and air conditioning device comprising:
an outdoor unit;
a heat exchanger accommodated in a housing of the outdoor unit; and
a blower disposed atop the housing,
wherein the housing includes:
a side cover for covering sides of the outdoor unit;
a bottom base for covering a bottom of the outdoor unit; and
a foot portion disposed under the bottom base having a top portion that engages the bottom base of the outdoor unit and a bottom portion,
wherein the bottom portion of the foot portion includes opposite end portions that are configured to engage a stand and a middle portion extending between the opposite end portions, a raised portion that is unitary with the bottom portion and extends upwardly from the bottom portion along one edge of the bottom portion, wherein the raised portion extends upwardly to terminate below the top portion and has a first height along the middle portion and a second height along the opposite end portions, and wherein the first height is greater than the second height.

2. The refrigeration and air conditioning device according to claim 1 , wherein
the opposite end portions of the bottom portion of the foot portion each include a through hole through which fasteners are disposed to fix the foot portion to a stand, and
wherein the raised portion extends upwardly to the second height in an area disposed adjacent to the through holes.

3. The refrigeration and air conditioning device according to claim 1 , wherein
the bottom portion of the foot portion has a width dimension and the first height of the raised portion is 60% or less of the width dimension of the bottom portion of the foot portion.

4. The refrigeration and air conditioning device according to claim 2 , wherein
the bottom portion of the foot portion has a width dimension and the first height at the mid-point thereof is 60% or less of the width dimension of the bottom portion of the foot portion.

5. A refrigeration and air conditioning device comprising:
an outdoor unit;
a heat exchanger accommodated in a housing of the outdoor unit; and
a blower disposed atop the housing,
wherein the housing includes:
a side cover for covering sides of the outdoor unit;
a bottom base for covering a bottom of the outdoor unit; and
a foot portion disposed under the bottom base having a top portion that engages the bottom base of the outdoor unit and a bottom portion,
wherein the bottom portion of the foot portion includes opposite end portions having a first width that are configured to engage a stand and a middle portion extending between the opposite end portions having a second width, a raised portion that is unitary with the bottom portion and extends upwardly from the bottom portion along one edge of the bottom portion between the opposite end portions and along the middle portion, wherein the raised portion extends upwardly to terminate below the top portion, and wherein the first width at the opposite end portions is wider than the second width of the bottom portion at the opposite end portions.

6. The refrigeration and air conditioning device according to claim 5 , wherein
the opposite end portions of the bottom portion of the foot portion each include a through hole through which fasteners are disposed to fix the foot portion to a stand, and
wherein the raised portion extends upwardly to a height dimension approximately equal to a difference in the dimensions of the first and second widths of the bottom portion of the foot portion.
