Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention includes a plurality of vertically elongated outdoor units each having a rectangular casing with a height longer than its depth, which is installed on a rooftop where the installation location is narrow. The present invention relates to air conditioners, and particularly to the installation structure of these outdoor units.

[Prior Art] Conventional air conditioners, especially for buildings, are designed to have a rectangular parallelepiped shape with a height longer than the depth of the outdoor unit casing in order to reduce the installation area, since the outdoor unit is installed on a narrow rooftop or other location. It was common to have a configuration in which suction was carried out from the front surface and discharged from the top surface. In this case, if only one outdoor unit is installed, fix the front and rear of the installation feet to the installation surface with bolts at four locations, but two
When installing a stand, it is preferable to install it back-to-back with the backs of the stand close together to increase the floor space, prevent it from collapsing due to strong winds or earthquakes, and save space. It could not be fixed to the installation surface.

[Problems to be solved by the invention] As described above, when installing vertically long outdoor units in conventional air conditioners on rooftops, etc., even if two units are installed back to back, they cannot be fixed to the installation surface on the back side. It was not perfect and had problems such as the risk of collapse due to strong winds or earthquakes.

This invention was made to solve the above problems.Even if two vertically long outdoor units are installed back to back, they can be securely fixed to the installation surface, and there is no risk of them collapsing even in strong winds or earthquakes. It is an object of the present invention to provide an air conditioner in which a fixing means for an outdoor unit can be obtained at low cost.

[Means for Solving the Problems] An air conditioner according to the present invention has two outdoor units each having a rectangular parallelepiped housing whose height is longer than its depth, and which is installed back to back, and the front lower part of each of the outdoor units is installed back to back. is fixed to the installation surface using installation feet, and the upper parts of both housings are connected and fixed using a connecting member.

[Function] In this invention, the front surfaces of two outdoor units are fixed to the installation surface, and the ground contact area is made as large as that of two outdoor units by connecting them with a connecting member at the upper part of the housing. Therefore, in the event of strong winds or earthquakes, the stress is dispersed, increasing the strength, preventing the casing from tipping over, and ensuring that it is firmly fixed to the installation surface.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the installed state of the outdoor units in one embodiment of the present invention. ) (l

In this way, two flat plates (4) (4') are used to connect and fix the two outdoor units at the top of the casings (1) (1'), and the installation feet (6) are installed at the bottom of the front of each outdoor unit. (6
) is fixed to the installation surface (8) with bolts (7) (7'), so the contact area of the outdoor unit is widened, the stress caused by strong winds or earthquakes is dispersed, and it does not fall over or become distorted. This also reduces the number of failures. Also bolt (5) (
The insertion hole 5') can be used as a bolt hole when transporting by hanging from a rope.

FIG. 2 is a perspective view showing how outdoor units of different sizes are installed in another embodiment of the invention.

In the figure, (9) (9'') are two elongated L-shaped plates that are connecting members, and are attached along the rear edges of the upper surface of the housing (1) (1') that touch each other. ) (9a')

The upper parts of the casings (1) and (1') are connected and fixed, producing the same effect as in FIG. Furthermore, although this embodiment shows an example in which outdoor units of different sizes are installed, the L-shaped plates (9) (9') can also be used for units of the same size as shown in Fig. 1. Of course. In addition, this L-shaped plate is 1

Furthermore, since the bolts are fixed internally, the bolts are not visible from the outside, and the aesthetic appearance is not compromised.

In addition to the above-described embodiments, one elongated flat plate member is arranged as an upper connecting member of two outdoor unit casings, straddling the cylindrical casings along the mutually contacting rear edges of the top surfaces of each casing. It may be fixed.

[Effects of the invention] As described above, according to this invention, the lower front surfaces of the outdoor unit casings installed back to back are fixed to the installation surface with the installation feet, and the upper parts of the cylindrical casings are connected and fixed with the connecting member. This has the effect of dispersing the stress that occurs during strong winds or earthquakes, ensuring secure fixation to the installation surface, eliminating distortion and overturning, reducing failures, and improving safety. Moreover, since the structure is such that a simple connecting member can be easily attached, it also has the advantage of being inexpensive and economical.
