Description

Base for air conditioner

technical field

The utility model relates to a base for an air conditioner, in particular to a base for an air conditioner which is applicable to flat ground and inclined roofs.

Background technique

Generally, as bases (stands) for mounting outdoor units of air conditioners, bases for air conditioners for flat ground and bases for air conditioners for sloped roofs are produced separately. In addition, in order to increase versatility, an air conditioner base that doubles as an air conditioner base for flat ground and an air conditioner base for sloped roofs is also produced. For example, the base for an air conditioner disclosed in Non-Patent Document 1 is basically for flat ground, but it can also be used for sloping roofs and sloping ground by changing the height of each support. In the case of such an air conditioner base, the actual length of the rear support can be shortened by lowering the installation position of the horizontal frame with respect to the rear support which is the higher side of the inclination. Thereby, the base for air conditioners for flat ground can be installed on a sloping roof or a sloping ground.

Non-Patent Document 1: Installation Instructions [C-NG5·C-NG5-L Type for Flat/Sloping Roofs] of Nippon Kiatsu Chiya Co., Ltd.

However, when the above-mentioned base for an air conditioner is installed on a sloped roof, since the horizontal frame on which the outdoor unit is placed is installed above the roof away from the roof, there is a problem of lack of stability. In addition, since the upper ends of the rear pillars protrude a lot upward from the horizontal frame, not only the appearance is poor, but also the workability when installing the outdoor unit of the air conditioner is also poor. In addition, in snowy areas, in order to avoid the influence of snow, the outdoor unit of the air conditioner is mostly installed under the upper roof. In this case, it is preferable to install the outdoor unit on the sloped roof as close as possible to the outer wall of the upper floor. However, the existing bases for air conditioners cannot satisfy such demands.

Utility model content

The purpose of this utility model is to provide an air conditioner base, which can be installed close to the outer wall of the upper floor when it is installed on a sloped roof as an air conditioner base for flat ground and sloped roofs.

In order to solve the above problems, according to the first aspect of the utility model, there is provided a base for an air conditioner, the base for an air conditioner includes: a pair of horizontal frames extending laterally; A pair of longitudinal frames between the two parts; four connecting parts connecting each end of the horizontal frame and each end of the longitudinal frame; detachably fixed on each connecting part and extending in the vertical direction; the lower ends of the pillars and an adjuster for adjusting the height of each pillar; and bolts for mounting the adjuster on each pillar. The adjuster includes: a long bolt hole extending along the height direction of the pillar and through which the bolt penetrates; and a screw through hole through which a screw for fixing the pillar to the rear connection part passes through. The side connection part is a connection part arranged on the inclined higher side among the four connection parts. In addition, the adjuster, as a fixed part relative to the outer wall of the building, is directly mounted on the rear connection part by screws.

According to this configuration, when the base for the air conditioner is placed on the sloping roof, the rear portion of the horizontal frame composed of the vertical frame and the horizontal frame can be directly attached to the outer wall of the upper floor via the adjuster. Therefore, when using the air conditioner base for a sloping roof, the outdoor unit can be attached close to the outer wall, and the influence of snow accumulation can be alleviated.

In this assembly example 3, the length of the support column 3 on the rear side is actually shortened so that the base for the air conditioner can be attached to the sloped roof R. As shown in FIG.

As shown in FIG. 9 , the screw through hole located below the uppermost stage is selected as the through hole 33 for fixing the support column 3 to the rear connecting portion A. As shown in FIG. Thereby, the length of the rear side strut 3 is substantially shortened. In addition, in this assembly example 3, the upper part of the support|pillar 3 on a rear side protrudes upward rather than a horizontal frame. Then, the base for the air conditioner is fixed to the pillar supporting the outer wall W of the building by using the hook S through the screw through hole 33 formed in the protruding portion. In addition, in this assembly example 3, in order to stably attach the base for the air conditioner to the uneven surface of the sloped roof R, a flat plate made of wood is bridged between the adjuster 4 on the right and the adjuster 4 on the left. Shaped parts7.

According to the base for an air conditioner having the above-mentioned structure, the following effects can be obtained.

(1) The adjuster 4 includes: bolt long holes 43 extending in the height direction of the pillar 3; and screw through holes 45 for functioning the adjuster 4 as a fixing member to the outer wall W of the building. In this case, instead of the pillar 3 , the adjuster 4 can be directly attached to the rear connection portion A as a fixing member with tapping screws 61 . In this way, the base for the air conditioner for a sloped roof can be attached close to the outer wall W, and the influence of snow accumulation can be alleviated. Also, in this case, since the support 3 is not attached to the rear side of the air conditioner base, the horizontal frame is not separated upward from the inclined roof R, and the stability of the air conditioner base is improved. In addition, since the support 3 does not protrude upward at the rear of the horizontal frame, the base for the air conditioner is beautiful, and it is easy to install the outdoor unit of the air conditioner.

(2) The adjuster 4 includes: a long bolt hole 43 extending in the height direction of the pillar 3; and screw through holes 45, 46 for making the adjuster 4 function as a leg provided on an inclined surface. In this case, instead of the pillar 3 , the adjuster 4 can be directly attached to the rear connection portion A by using the self-tapping screws 61 , 62 as legs for inclined surfaces. In this way, when it is difficult to directly attach the horizontal frame to the outer wall W, the horizontal frame can be directly mounted on the sloped roof R without providing the support 3 at the rear of the horizontal frame. Therefore, even in this case, the horizontal frame does not separate too much upward from the slope roof R, and the stability of the base for air conditioners improves. In addition, since the support 3 does not protrude upward at the rear portion of the horizontal frame, the base for the air conditioner is beautiful, and the installation workability of the outdoor unit for the air conditioner is also improved.

(3) The screws for fixing the pillar 3 to the connection portion A are self-tapping screws 61 . A pair of protrusions 16 and 17 extending in the longitudinal direction of the horizontal frame 1 are formed on the horizontal frame 1 . Each ridge part 16, 17 is formed with each notch 16a, 17a extended in the longitudinal direction of each ridge part 16, 17. As shown in FIG. The ends of the respective cutouts 16a, 17a are opened on the end surface 1a of the horizontal frame 1, respectively. In addition, the outer side wall 22 of the vertical frame 2 and the side wall 31 of the column 3 overlap the end surface 1 a of the horizontal frame 1 at the connecting portion A of the horizontal frame 1 and the vertical frame 2 and the fixing portion between the connecting portion A and the column 3 . And, by screwing two self-tapping screws 61 penetrating through the outer wall 22 of the vertical frame 2 and the side wall 31 of the pillar 3 respectively into the slots 16a, 17a of the horizontal frame 1, the vertical frame 2 and the pillar 3 are fixed on the horizontal frame 1. On the horizontal frame 1. In this case, there is no need to provide other fixing members at the connecting portion A between the horizontal frame 1 and the vertical frame 2 and the fixing portion between the connecting portion A and the column 3, so that the number of parts can be greatly reduced. Moreover, when manufacturing the base for air conditioners of a different size according to the kind of air conditioner, the same attachment structure can be employ|adopted only by changing the length of the horizontal frame 1 and the vertical frame 2. Moreover, when changing the height of the base for air conditioners, the same mounting structure can be employ|adopted only by changing the length of the support|pillar 3. In other words, common use of components can be realized. In addition, since the protrusions 16 and 17 are formed along the longitudinal direction of the horizontal frame 1, the bending strength in the longitudinal direction of the horizontal frame 1 increases.

(4) The vertical frame 2 is formed with the protrusion 25 extending in the longitudinal direction of the vertical frame 2 . A notch 25 a extending in the longitudinal direction of the protrusion 25 is formed on the protrusion 25 . In addition, the end portion of the slot 25 a is open at the end surface 2 a of the vertical frame 2 . And the pillar 3 is fixed on the vertical frame 2 by screwing the self-tapping screw 62 passing through the side wall 31 of the pillar 3 into the slot 25 a of the vertical frame 2 . Thereby, the fixing strength of the support|pillar 3 to the connection part A is further improved. In addition, since the protrusions 25 are formed along the longitudinal direction of the vertical frame 2, the bending strength in the longitudinal direction of the vertical frame 2 increases.

(5) On the upper side wall 11 of the horizontal frame 1, the protrusion 16 having the notch 16a is formed, and on the lower side wall 13 of the horizontal frame 1, the protrusion 17 having the protrusion 17a is formed. Then, the vertical frame 2 and the pillar 3 are fixed to the horizontal frame 1 by screwing self-tapping screws 61 into these notches 16a, 17a. Since the adjuster 4 is attached to the rear connection portion A using the two tapping screws 61 in this way, the attachment strength of the adjuster 4 to the connection portion A is improved.

(6) The notches 16a and 17a are arranged on a vertical line parallel to the outer wall of the building. Also, the adjuster 4 includes: a first wall portion 41 that abuts on the side surface of the pillar 3; and a second wall portion 42 that abuts on the installation surface. Bolt slots 43 extending perpendicularly to the second wall portion 42 are formed in the first wall portion 41 . Furthermore, the first wall portion 41 has a pair of screw through holes 45 symmetrical to the axis of the bolt long hole 43 . Tapping screws 61 to be screwed into the notched grooves 16 a and 17 a of the horizontal frame 1 pass through these screw through holes 45 . In addition, the first wall portion 41 has a screw through hole 46 on the axis line of the bolt long hole 43 and on the side opposite to the second wall portion 42 with respect to the bolt long hole 43 . A self-tapping screw 62 to be screwed into the notch 25 a of the vertical frame 2 penetrates through the screw through hole 46 . Also, the distance between the pair of screw through holes 45 and the distance from one of the pair of screw through holes 45 to the screw through hole 46 are equal to the distance between the notches 16 a and 17 a of the horizontal frame 1 .

Therefore, when the adjuster 4 is fixed to the lower end of the pillar 3 using the bolt long hole 43 , the height of the pillar 3 can be adjusted by changing the position of the bolt relative to the bolt long hole 43 . Furthermore, by changing the attachment angle of the adjuster 4 with respect to the support column 3, the second wall portion 42 of the adjuster 4 can also be inclined in accordance with the inclination of the installation surface.

In addition, when the adjuster 4 is attached to the rear connection portion A using the pair of screw through holes 45 , the second wall portion 42 of the adjuster 4 can be brought into contact with the outer wall W. As shown in FIG. On the other hand, when the adjuster 4 is attached to the rear connection portion A using one of the pair of screw through holes 45 and the screw through hole 46 , the second wall portion 42 of the adjuster 4 can be inclined. Therefore, by directly attaching the adjuster 4 to the rear connecting portion A and inclining the adjuster 4 to the lower end of the front pillar 3, the base for the air conditioner can be installed on an inclined surface such as a sloping roof or a sloping ground. superior.

(7) Also, in this case, the adjuster 4 can be used both left and right by using any one of the pair of screw through holes 45 symmetrical to the axis of the bolt long hole 43 to change the left and right direction of the adjuster 4 .

(8) The notches 16 a and 17 a of the horizontal frame 1 and the notch 25 a of the vertical frame 2 are formed in a cylindrical shape. Therefore, by screwing in the tapping screws 61, 62, the range of the screw grooves formed on the inner peripheral surfaces of the cut grooves 16a, 17a, 25a is enlarged. Thus, the self-tapping screws 61 and 62 increase the fixing strength of the horizontal frame 1 , the vertical frame 2 , and the pillar 3 , or the fixing strength of the horizontal frame 1 , the vertical frame 2 , and the adjuster 4 .

(9) The horizontal frame 1, the vertical frame 2, and the pillar 3 are made of aluminum or an aluminum-based alloy, and are formed by extrusion. Therefore, the horizontal frame 1 and the vertical frame 2 can be manufactured precisely and simply without performing complicated operations such as bending. In addition, by using aluminum or an aluminum-based alloy, it is also possible to reduce the weight of the base for an air conditioner. Therefore, handling at the time of transportation and assembly becomes easy, and workability improves.

(10) Both the horizontal frame 1 and the vertical frame 2 are formed in a cylindrical shape. Therefore, the bending strength of the horizontal frame 1 and the vertical frame 2 can be improved. Moreover, at the connection part A, the horizontal frame 1 and the cylindrical part of the vertical frame 2 are attached so that they may overlap. Therefore, the strength reduction of the connection part A can be suppressed.

(11) The protrusions 16 and 17 of the horizontal frame 1 and the protrusions 25 of the vertical frame 2 are provided in the cylindrical portions of the respective frames 1 and 2 . Therefore, the protruding part cannot be seen from the outside, and it becomes beautiful.

In addition, this embodiment can also be changed as follows.

In this embodiment, the horizontal frame 1, the vertical frame 2, and the pillar 3 are fixed in a state where the horizontal frame 1 and the vertical frame 2 overlap each other, but the horizontal frame 1 and the vertical frame 2 can also be fixed directly. It is also possible to fix the struts 3 on these frames 1,2.

In this embodiment, the pillar 3 having a certain height is used, but a plurality of pillars 3 having different lengths may be prepared in order to select a pillar 3 having a height suitable for installation conditions of the air conditioner base.

In the assembly examples 1 and 2 of the air conditioner base of this embodiment, as in the case of the assembly example 3, a flat plate made of wood or the like may be erected between the left adjuster 4 and the right adjuster 4 Shaped parts7. By doing so, it is possible to stably attach the base for the air conditioner to the uneven surface of the inclined roof R. FIG.

The adjuster 4 is mounted on the lower end of the pillar 3 through the square neck bolt 63, but the bolt through hole 34 of the pillar 3 can also be made into a round hole, and the adjuster 4 can be fixed on the pillar 3 by ordinary bolts.

Self-tapping screws 61 and 62 were used to install the horizontal frame 1, vertical frame 2, and pillar 3, but ordinary screws can also be used. In this case, there is an advantage that after disassembling the installed air conditioner base When reassembling, the strength of the threaded portion can be maintained.

The cylindrical parts in the horizontal frame 1 and the vertical frame 2 may also be omitted.

The notches 16a, 17a of the horizontal frame 1 and the notch 25a of the vertical frame 2 may have shapes other than cylinders. For example, a slot may be formed between a pair of parallel walls, and tapping screws 61 and 62 may be screwed into the inner surfaces of the slot.

The notches 16a, 17a of the horizontal frame 1 and the notches 25a of the vertical frame 2 are formed over the entire length of the horizontal frame 1 and the vertical frame 2, but may be within a predetermined range in the longitudinal direction of the horizontal frame 1 and the vertical frame 2. form.

The horizontal frame 1 and the vertical frame 2 may be formed of materials other than aluminum or aluminum-based alloys by methods other than extrusion.
