Description

The present invention relates to a ceiling structure for an air conditioner.

Conventionally, there is an air conditioner as described in, for example, Patent Document 1. This relates to a frame that constitutes the casing of the air conditioner. The frame has a hollow main member and a corner connecting member that connects the main member. The corner connecting member has a connecting main body portion that has three corner outer surfaces that are at right angles to each other, and a connecting insertion portion that extends from the connecting main body portion in each of the three axial directions that are at right angles to each other and is inserted into the main member.

When placing such an air conditioner outdoors, the top panel 101 of the casing 100 is tilted to form a drainage gradient, as shown in Figures 9 to 12.

For this reason, an inclined member 103 is placed on the frame 102 of the casing 100 , an outer wall panel 104 is extended upward so as to surround the inclined member 103 , and a top panel 101 is placed on the inclined member 103 .
Patent Publication 2018-146147

In the frame 102 of a conventional casing 100, the connecting insertion portions of the corner connecting members 105 extend in the axial direction of each of the three axes that are perpendicular to each other, and the main members 106 are connected to each other at right angles. For this reason, the ceiling frame that supports the top panel 101 cannot be formed in an inclined state, and in order to arrange the top panel 101 at an incline, it was necessary to place an inclined member 103 between the ceiling frame and the top panel 101.

For this reason, in order to place the air conditioner outdoors, it is necessary to create the inclined member 103 separately from the original casing. In addition, the total height of the original casing is increased by the amount of the inclined member 103.

Furthermore, if the top panel 101 itself is to be inclined, a separate top panel with a different shape from the normal one must be manufactured, and a dedicated manufacturing process is required to manufacture the inclined top panel, which reduces work efficiency.

The present invention aims to solve the above-mentioned problems and provide a ceiling structure for an air conditioner that allows the top panel to be easily positioned at an angle.

In order to solve the above problems, the ceiling structure for an air conditioner of the present invention is an air conditioner to be placed outdoors, the casing having a top panel that is arranged at an angle to form a drainage gradient, and a ceiling frame that supports the top panel, the ceiling frame having a plurality of main members that correspond to the four sides of the top panel and fix the top panel , and corner connecting members that connect each of the main members, each of the main members being made of a hollow member, the corner connecting members having a connecting main body portion and a plurality of connecting insertion portions that extend from the connecting main body portion and are inserted into each of the main members, the plurality of main members that correspond to the four sides of the top panel, and the main members that are erected like columns supporting the ceiling frame , the connecting insertion portions of a pair of corner connecting members connected to both ends of the main members that are arranged toward the tilt direction of the top panel face each other, the axis of the connecting insertion portion of one corner connecting member located above is inclined downwardly toward the tilt direction of the top panel, and the axis of the connecting insertion portion of the other corner connecting member located below is inclined upwardly toward the tilt direction of the top panel.

The ceiling structure of the air conditioner of the present invention is characterized in that the connecting body part of one corner connecting member located at the top has a corner outer surface that corresponds to the top panel with a downward slope in the inclination direction of the top panel, and the connecting body part of the other corner connecting member located at the bottom has a corner outer surface that corresponds to the top panel with an upward slope in the inclination direction of the top panel.

In the ceiling structure of the air conditioner of the present invention, the corner connecting member has a step surface corresponding to the thickness of the main member at the boundary between the connecting body portion and the connecting insertion portion, and the step surface expands in a direction perpendicular to the axis of the connecting insertion portion and abuts against the end face of the main member.

In the ceiling structure of the air conditioner of the present invention, the top panel has a convex portion on the underside that fits into the ceiling frame.

As described above, according to the present invention, when the top panel is arranged at an angle, the corner connecting members can be replaced with corner connecting members for an angled arrangement to create an inclined state for the ceiling frame, so that the top panel can be inclined without having anything between the ceiling frame and the top panel. Therefore, the top panel can be arranged at an angle without increasing the overall height of the casing. In addition, there is no need to separately manufacture a top panel with a shape different from that of a normal top panel.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(Overall structure)
As shown in Figure 1, the casing 1 of the air conditioner comprises a plurality of exterior wall panels 2 forming side walls, a plurality of top panels 3 forming the ceiling, and an internal panel 4 forming a partition wall dividing the space inside the casing 1 into a plurality of chambers, all of which are fixed to a frame 6. A door panel 7 is disposed at the front opening of each chamber of the casing 1, and the door panel 7 is attached to the frame 6 so as to be openable and closable.

The inside of the casing 1 is divided into an outdoor air chamber 8, an air supply chamber 9, and a fan chamber 10. A filter unit 16 consisting of a pre-filter 14 and a medium performance filter 15 is attached to the outdoor air chamber 8. A heat exchanger 19 consisting of a hot and cold water coil is attached to the air supply chamber 9. An air supply fan device 21 consisting of a plug fan is installed in the fan chamber 10. (Operation of the air conditioner)
(Frame structure)
As shown in FIGS. 1 to 5 and 7 , the casing 1 has a drain pan 51 disposed on a stand 50 , and a frame 6 disposed on the drain pan 51 .

The frame 6 has hollow main members 610 which form the structural material of the casing 1 arranged in a pillar-like state at the four corners of each frame 50, and has main members 610 laid down like crossbars between the upright main members 610. Furthermore, intermediate members 620 which form auxiliary materials are arranged between a pair of parallel main members 610, and the main members 610 are connected to each other, and the intermediate members 620 are fixed to the main members 610, or the intermediate members 620 are connected to each other.
(Connected structure)
As shown in FIGS. 2, 3 and 7, the frame 6 of the casing 1 includes a bottom frame 650 forming the bottom, a ceiling frame 660 and a main member 610 standing like a pillar, which are connected by corner connecting members 630 and 640.

The corner connecting members 630, 640 that connect the main members 610 to each other are made of resin material and have solid connecting body parts 631, 641 and hollow connecting insertion parts 632, 642 that are inserted into the main members 610.

As shown in FIG. 3, the connecting body 631 of the corner connecting member 630 constituting the bottom frame 650 has three outer corner surfaces 633 that form a part of the outer frame surface of the frame 6 and form an outside corner angle at a right angle to each other, and three inner corner surfaces 634 that form a part of the inner frame surface of the frame 6 and form an inside corner angle at a right angle to each other.

The connecting insert portion 632 extends from the connecting body portion 631 in the direction of each of the three axes that are perpendicular to each other, and has a step surface 635 at the boundary between the connecting body portion 631 and the connecting insert portion 632, which corresponds to the thickness of the main member 610.

When the main member 610 is inserted into the connecting insertion portion 632 of the corner connecting member 630, the main member outer surface 611 of the main member 610 and the corner outer surface 633 of the corner member 630 are continuous in a flat plane to form the frame outer surface.

As shown in FIG. 7, the corner connector 640 that constitutes the ceiling frame 660 has the same basic structure as the corner connector 630 that constitutes the bottom frame 650.

That is, the three outer corner surfaces 643 of the connecting body 641 that form part of the outer frame surface of the frame 6 form an outside corner angle, and the three inner corner surfaces (not shown) that form part of the inner frame surface of the frame 6 form an inside corner angle.

The connecting insert portion 642 extends from the connecting body portion 641 in each of the three axial directions, and has a step surface 645 at the boundary between the connecting body portion 641 and the connecting insert portion 642, the step surface 645 being equivalent to the thickness of the main member 610.

The ceiling frame 660 has a rectangular shape with short and long sides in a plan view, with the main members 610 forming the short sides arranged in the inclination direction of the top panel 3, which in this case is a downward inclination direction from the front side to the back side of the casing 1, and corner connecting members 640 are arranged on both ends of the main members 610 on the short sides. The corner connecting members 640 connect the three main members 610 by inserting the main members 610 on the short sides, the main members 610 on the long sides, and the main members 610 erected like pillars into the respective connecting insertion portions 642.

As shown in FIG. 7, one of the pair of corner connecting members 640 connected to both ends of the main member 610 on the short side is located above the other in the inclination direction of the top panel 3. The axis of the connecting insertion portion 642 of one of the corner connecting members 640 located above is inclined downward toward the inclination direction of the top panel 3, and the axis of the connecting insertion portion 642 of the other corner connecting member 640 located below is inclined upward toward the inclination direction of the top panel 3. The inclination angle of the axis of the connecting insertion portion 642 is 1/50 here, and the difference h in height of the pair of corner connecting members 640 connected to both ends of the main member 610 on the short side corresponds to the distance L between the pair of corner connecting members 640 facing each other via the main member 610 on the short side, and is h = L x 1/50.

The step surface 645 at the boundary between the connecting body portion 641 and the connecting insert portion 642 expands in a direction perpendicular to the inclined axis of the connecting insert portion 642 and abuts against the end face of the main member 610.

As a result, as shown in Figures 4 and 5, the short side main member 610 is inclined at an inclination angle of 1/50 between a pair of corner connecting members 640 connected to both ends of the short side main member 610, the ceiling frame 660 is inclined, and the top panel 3 placed on the ceiling frame 660 is inclined from the front side to the back side of the casing 1.

In this way, when the top panel 3 is arranged at an angle, by using the corner connecting member 640 for an angled arrangement instead of the normal corner connecting member 630, the ceiling frame 660 can be made to be in an angled state, so that the top panel 3 can be inclined without having anything interposed between the ceiling frame 660 and the top panel 3. Therefore, the top panel 3 can be arranged at an angle without increasing the overall height of the casing 1.

In addition, there is no need to separately manufacture a tabletop panel 3 with a shape different from that of a normal tabletop panel 3.

Furthermore, the corner connecting member 640 for inclined arrangement that constitutes the ceiling frame 660 can also be configured as shown in Figure 8.

That is, the connecting body 641 of one of the corner connecting members 640 located at the top has a corner outer surface 643 that corresponds to the top panel 3 and slopes downward in the direction of the inclination of the top panel 3, while the connecting body 641 of the other corner connecting member 640 located at the bottom has a corner outer surface 643 that corresponds to the top panel 3 and slopes upward in the direction of the inclination of the top panel 3.

6, the top panel 3 may have a convex portion 31 on its underside that fits into the frame of the ceiling frame 660. This structure may also be applied to cases where the top panel 3 is not disposed at an angle.
(Fixing structure details)
The exterior wall panel 2 and the top panel 3 are fixed to the main member 610 and intermediate member 620 of the frame 6 with panel fixing screws 701 which are drill screws.
