Description

[Detailed Description of the Invention] This invention relates to an air conditioner, and particularly to an improvement of its installation level adjustment device.

A conventional floor-standing air conditioner and level adjustment screw structure were constructed as shown in FIGS. 1 to 3. That is, in FIGS. 1 to 3,
1 is the frame that serves as the framework of the air conditioner;
This frame 1 is constructed by a pair of side frames 2 having flanges formed by bending their peripheries, and a rear plate 3 superimposed on the rear flanges and fixed by screws or the like. 4 is a pair of side frames 2
The heat exchanger is detachably inserted and supported in a square hole 5 formed in the side frame 2, and has a piping connection port 41 led out to the outside of one side frame 2. A drain pan 6 is detachably inserted and supported in a through hole 7 formed in a substantially V shape below the square hole 5, and has a discharge port 61 led out of one side frame 2. Reference numeral 8 denotes an auxiliary drain pan provided below the discharge port 61 of the drain pan 6, and has a drain drain connection port 81 for discharging drain to the outside of the machine. 9 is a motor 10;
A blower consisting of a fan 11 and a mounting base 12, which connects a pair of side frames 2 via the mounting base 12.
is fixed below the drain pan 6. 13 is a suction port formed at the lower part between the side frames 2, and a filter 14 supported between both side frames 2 is attached to the suction port 13.
15 and 16 are first and second upper panels arranged in parallel with each other at a predetermined interval; 17 is a blowout grill provided between the first and second upper panels 15 and 16;
8 and 19 are end covers provided on both sides of the suction grill 17 and electrical panel covers; 20 is a side plate;
1 is the front panel, 22 is the base, and each of the above elements 15
Together with 21 to 21, they form the appearance of the air conditioner main body.

The air conditioner main body configured in this way includes the lower flange surface 23 of the side frame 2 and the base 2.
A cold/hot water pipe and a drain drainage pipe (both not shown) are placed on the floor with the bottom of the base 22 grounded, and are inserted through the insertion space in the base 22 and rise above the floor.
is connected to the piping connection port 41 led out from the heat exchanger 4 and the drain connection port 81 of the auxiliary drain pan 8 to perform heating and cooling operation. However, if the floor surface at this time is not level, or if one side of the air conditioner main body is lifted by piping rising from the floor surface, the lower flange surface 23 of the side frame 2 on one side will not touch the floor surface. As a result, the air conditioner body wobbles and becomes unstable, so it is adjusted using the level adjustment screw provided on the lower flange surface 23. However, the conventional level adjustment screw structure is as shown in Fig. 3. A nut 24 is welded to the upper surface of the lower flange surface 23 of No. 2, a bolt 25 is screwed into the nut 24, and the level is adjusted by the protruding height of the tip of the bolt 25.

However, with this level adjustment screw structure,
Since there are no other welding points in the manufacturing process of the side frame 2, a welding process is required only for nut welding, which not only requires space but also increases the cost of welding time and welding electricity costs.

Furthermore, level adjustment screws are not required when the floor surface is horizontal or depending on the height of the rising pipe, but in the conventional structure where the nut 24 is welded, it must be welded in case it is unnecessary. Furthermore, if the thickness of the side frame is made thinner in order to further reduce costs, the lower flange surface will be constantly deformed by the weight of the main body, making level adjustment useless. There were flaws.

This idea was developed in view of the above circumstances, and by removably inserting the female screw member into the convex part formed on the lower flange surface of the side frame and the notch provided on the vertical vertical wall of the side frame, it can be used as a substitute for a welding nut. This is an attempt to eliminate the above-mentioned drawbacks.

An embodiment of this invention will be described below.
Note that the configuration of the air conditioner main body is the same as that of the conventional example, so a description thereof will be omitted, and only the structure of the level adjustment screw will be described.

In FIGS. 4 to 6, 26 is an opening made by making a cut of a predetermined width in the lower flange surface 23 of the side frame 2, which is the installation surface of the air conditioner main body, and cutting and bending upward between the cuts. Part 27
This insertion portion 26 is an insertion portion of a female thread member having a
A through hole 28 for inserting a bolt is provided approximately at the center of the cut and raised piece 26a. The height dimension h of the opening 27 is greater than the thickness of the female thread member 30 having the female thread 29. On the other hand, at the base of the vertical wall of the side frame 2, a notch 31 extending from the lower flange surface 23 to the same height as the ceiling surface of the upper end convex part 26 is located at a position corresponding to the convex part 26, with a width exceeding the notch width of the convex part 26. It is set in. In addition, the female screw member 30 has one side close to the notch width of the convex portion 26 so that the female screw member 30 does not spin idly within the convex portion 26, and the other side has a length sufficient to allow the female screw member 30 to be inserted from the convex portion 26 into the notch 31. It is formed into a rectangle. Note that the convex portion 2
6 and the notch 31 are machined at the same time when the side frame 2 is machined from the sheet metal.

With this configuration, the female threaded member 30 is inserted into the protrusion 26 and the notch 31 from the opening 27 of the protrusion 26, and the through hole 28 and the female threaded member 30 are inserted into the protrusion 26 and the notch 31.
The bolt 25 is inserted into the through hole 28 from the through hole 28 side of the convex portion 26 until the female screw 29 of the convex portion 26 matches the female screw 29 of the female screw member 30. At this time, since the female threaded member 30 is dimensioned to prevent free rotation within the convex portion 26, the female threaded member 30 does not freely rotate within the convex portion 26 and the notch 31, and the screwing of the threaded portion progresses. reaches the floor surface, the upper surface of the female screw member 30 contacts the ceiling surface within the convex portion 26 and the upper end of the notch 31, and by further turning the bolt 25, the side frame 2
is lifted up. That is, the main body of the air conditioner can be lifted and the level adjustment function can be fully performed. Also, at this time, the weight of the main body is distributed between the upper end of the notch 31 and the convex portion 26, which have sufficient strength against the upward load, so the side frame 2
Even if the thickness of the plate is thin, the convex portion 26 and the lower flange surface 23 will not be deformed.

Incidentally, since the female screw member 30 and the bolt 25 are removable, they are set at the site where the main body is installed as described above only when level adjustment is required.

As described above, in this invention, a convex part having an opening for inserting a female screw member is cut and formed on the flange surface of the frame, which is the installation surface of the air conditioner main body, and a male screw member for level adjustment is installed on the top wall of the convex part. A through hole is provided for insertion, and a notch is provided at the base of the vertical wall of the side frame at the same height as the opening at a position corresponding to the convex portion, and the notch is inserted into the convex portion from the opening. Insert a female thread member with a female thread of the same length, insert the male thread member through the through hole,
Since it is designed to be screwed together with a female thread, there is no need to assemble it into the air conditioner body in advance like in conventional equipment, and it only needs to be installed when it is necessary to adjust the installation level during on-site installation. can be omitted, increasing manufacturing efficiency. The welding process is omitted, so welding reduces costs because time and electricity are not required.
Furthermore, since the screw member only needs to be inserted, there is a great advantage in that if level adjustment is not required, the manufacturer's installation work can be omitted and useless work can be eliminated.
