TECHNICAL FIELD OF THE INVENTION
The present invention relates to an installation leveling device for a large refrigerator for business use or the like.
[0002]
[Prior art]
First, FIG. 4 shows a configuration and an installed state of a large refrigerator to which the present invention is applied. In the figure, reference numeral 1 denotes a cabinet body of a refrigerator constructed of an insulated housing, reference numeral 2 denotes a front door thereof, and reference numeral 3 denotes a condensing unit of a refrigerator installed on the top of the cabinet body 1, which is superimposed on a bottom wall of the cabinet body 1. In the base frame provided in this manner, level adjusting bolts 4 also serving as installation support legs are dispersed and planted on the lower surface side at four corners thereof, and are installed on the floor via the bolts 4.
[0003]
These level adjustment bolts 4 are also called leveling screws, etc., and are screwed into the four corners of the base frame from the lower side and planted. When the refrigerator is installed, the protrusion height of each bolt 4 is individually adjusted. And serves to adjust the level so that the cabinet body 1 is in a horizontal posture with respect to the installation floor.
[0004]
[Problems to be solved by the invention]
By the way, in a state where the refrigerator is installed along the wall 5 of the building at the location as shown in FIG. 4 and a leveling operation is required from the condition of the installation floor surface, the conventional leveling device has the following structure. There is a work problem.
That is, the level adjustment bolt 4 implanted on the front side (door side) of the cabinet body 1 can be adjusted from the front using a tool such as a spanner, but the rear side of the cabinet body. In particular, the level adjustment bolt located on the corner side of the building has a narrow gap between the floor surface and the cabinet body 1 and cannot be reached far from the front of the refrigerator. Moreover, large refrigerators for business use are heavy in weight, and cannot be easily moved or lifted only by the human power of workers, which makes level adjustment extremely difficult.
[0005]
SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to solve the above-mentioned problems. Even when the refrigerator is installed at a predetermined installation location, the level adjustment bolt can be used without being restricted by the conditions of the installation location. An object of the present invention is to provide a refrigerator leveling device improved so that an adjusting operation can be performed from the inside of the cabinet of the cabinet body.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, a plurality of level adjustment bolts serving also as supporting legs are distributed around the lower surface of a base frame of a cabinet main body constructed of an insulated housing. In a refrigerator leveling device, which is planted and adjusts the level of the cabinet body by adjusting the bolts at the time of installation of the refrigerator, at least a level adjustment bolt attached to a rear side of the cabinet body is attached to a bottom of the cabinet body. A wall hole for adjustment work communicating with the bolt is opened in the wall (Claim 1), and is specifically configured in the following manner.
[0007]
(1) As the level adjusting bolt screwed into the base frame of the cabinet main body, a bolt having an engagement means capable of being connected to a tool is formed at the upper end of the shaft portion (claim 2).
(2) The wall hole is closed by the closing member (claim 3).
[0008]
With this configuration, when performing leveling in a state where the refrigerator is installed at a predetermined location at the location, the refrigerator is located at the rear side of the cabinet main body which is not accessible from the front through the gap between the refrigerator and the floor surface. For the level adjustment bolts, open the front door, remove the closing member that closed the wall hole formed in the refrigerator, and then use the wall hole opening in the bottom wall of the heat-insulating enclosure to operate the bolt for bolt operation. By inserting a tool and turning the level adjustment bolt, the leveling operation can be easily performed even when the cabinet body is installed in a predetermined position. After the leveling operation is completed, the wall hole is closed by the closing member, so that high heat insulation of the cabinet body can be secured.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described based on examples shown in FIGS. In the drawings of the embodiment, the same members corresponding to FIG. 4 are denoted by the same reference numerals.
First, in FIG. 1, the cabinet body 1 is a heat-insulating housing constructed of a heat-insulating panel having a heat-insulating material 1a such as urethane foam resin as a core material, and a base frame 6 made of a steel plate joined to a bottom wall thereof. Level adjusting bolts 4 which also serve as support legs are distributed at the four corners of the peripheral edge and are screwed so as to penetrate the base 6 from the lower surface side. The level adjusting bolt 4 has a grooved bolt formed with a bolt operating groove 4a for inserting a driver (screw operating tool) on the upper end surface of the shaft portion, that is, a tool (a driver in this embodiment). It is a bolt formed with connectable engaging means (a groove 4a in this embodiment), and has a pad-like leg piece 4b at the lower end in contact with the installation floor surface.
[0010]
On the other hand, a wall hole 1b for adjustment work communicating with the adjustment bolt 4 is opened in the bottom wall of the cabinet main body 1. The surrounding area of the wall hole 1b is surrounded by a heat insulating material 7, and the wall hole 1a is further covered with a heat insulating material. A heat insulating cover 9 is detachably attached to the upper opening through a sealing seal 8. The heat-insulating cover 9 constitutes a closing means for closing the wall hole 1b, and the heat-insulating cover 9 is formed by filling a heat-insulating material 9b inside a cap-shaped cover 9a made of sheet metal, and has a flange portion projecting right and left from the cover 9a. Are fastened to the bottom wall of the cabinet body 1 via set screws 10. In addition, among the plurality of level adjusting bolts 4 distributed and implanted in the peripheral area on the lower surface side of the base frame 6, at least the bolt located at the rear side of the cabinet body 1 as shown in FIG. The bolts mounted on the front side have a conventional mounting structure. Note that the seal 8 is not always necessary, and may be omitted particularly when airtightness is not required inside the refrigerator.
[0011]
In the above configuration, when performing leveling with the refrigerator installed at the location, the heat insulating cover 9 fixed on the bottom wall in the cabinet of the cabinet body 1 was removed together with the seal 8 as shown in FIG. Above, the driver 11 is inserted into the groove 4a of the level adjustment bolt 4 through the wall hole 1a opened in this part, and the bolt 4 is turned to the left or right so that the installation posture of the cabinet body 1 is horizontal with respect to the installation floor. Adjust the level so that After the leveling operation is completed, the heat insulating cover 8 is returned to the original position and fixed, and the wall hole 1a is closed with heat.
[0012]
【The invention's effect】
As described above, according to the configuration of the present invention, the work of adjusting the level adjustment bolts performed when the heavy-duty large refrigerator is installed at the location destination can be performed from the inside of the refrigerator without being restricted by the conditions of the installation location. It can be easily performed using tools, and the work of installation work can be improved.
