 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly, to a structure for fixing a protective net arranged on the back of an outdoor unit of a large air conditioner.

[0002]

[Prior art]

 In order to support multiple indoor units that air-condition multiple rooms with one outdoor unit, two compressors, blowers, and heat exchangers are built in the housing consisting of the base, outer shell, and protective net. As shown in FIG. 2, in a large outdoor unit in which a plurality of indoor units are divided into two systems for operation, a partition plate 6 is provided on a tray-shaped base 5 to exchange heat with the machine room 7. It is divided into a chamber 8 and a compressor 2 and a control device (not shown) are housed in the machine chamber 7, and a heat exchange chamber 8 surrounded by the base 5, the partition plate 6 and the ceiling plate 9a. Is installed with the two heat exchangers 4a and 4b, one above the other, together with the respective blowers 3 through the motor mounting plate 10, so that the efficiency of the heat exchanger 4 due to the dispersion of the intake air passage is not reduced. Separate air passages are formed by sandwiching the upper and lower partition plates 11. The lower heat exchanger 4a installed on the base 5 is fixed to the base 5 and the partition plate 6, and the upper and lower partition plates 11 are placed on the lower heat exchanger 4a and locked to the locking portions 12 of the partition plate 6. The motor mounting plate 10 which is erected on the base 5 and the blowout port cover (not shown) are fixed to each other. The upper heat exchanger 4b is placed on the upper and lower partition plates 11 and fixed to the upper and lower partition plates 11 and the partition plate 6. As shown in FIG. 3, in order to protect the exposed fins of the heat exchanger 4, a protective net 13 is screwed to the edge of the outer case 9 at the rear opening of the casing 1. However, the protective net 13 is formed by welding the numbered wires into the vertical rails 14 and the horizontal rails 15 in a grid shape, and only the ends of the horizontal rails 15 are screwed and the central portion is not fixed and floats. Therefore, it resonates with the vibration of the blower 3 and causes noise, and the fins of the protective net 14 may be damaged due to the inward bending.

[Problems to be solved by the device]

 In order to solve the above-mentioned problems, an object of the present invention is to provide an outdoor unit of an air conditioner having a structure in which upper and lower partition plates are engaged and fixed to a protective net to prevent vibration and bending. Ok

[0004]

[Means for Solving the Problems]

 According to the present invention, a partition plate is erected on the base, a compressor is arranged in a machine room partitioned by the partition plate, and the heat exchange chamber is partitioned vertically by the upper and lower partition plates to form a heat exchanger and a blower. And a protective net on the back surface of the heat exchanger.The rear end of the upper and lower partition plates is extended to form a hook-stop, and the hook-stop is attached to the hook-stop. It is characterized in that the cross rail of the above-mentioned protective net is locked. Further, the rear end portions of the upper and lower partition plates are extended with a width that fits in the space between the vertical bars of the protective net attached to the back surface of the heat exchanger, and the diameter of the horizontal bars of the protective net is defined as an inner diameter. It is characterized by forming a hanging portion in a downward gutter shape that is wound more than the circular shape. Further, a horizontal rail at the center of the protective net attached to the back surface of the heat exchanger is arranged at the position of the hooking portion provided by extending the rear end of the upper and lower partition plates. Is characterized by.

[0005]

[Action]

 According to the present invention, the rear end of the outer periphery of the upper and lower partition plates is extended to the horizontal crosspiece at the center of the protective net disposed at the same height as the upper and lower partition plates, and the diameter of the horizontal net of the protective net is set to the inner diameter. It is possible to fix the protective net by hooking the hanging part formed in the shape of a downward gutter that is wound more than the semicircle using the springiness of the winding.

【Example】

 An embodiment of the present invention will be described with reference to FIG. In the heat exchange chamber 8 surrounded by the base 5, the partition plate 6, the ceiling plate 9a, and the air outlet cover 16, the blowers in which the heat exchangers 4a and 4b are attached to the motor mounting plate 10 with the upper and lower partition plates sandwiched therebetween. It is installed together with. An upper and lower partition plate 11 is placed on the lower heat exchanger 4a installed on the base 5, and is fixed to the locking portion 12 of the partition plate 6, the motor mounting plate 10 and the outlet cover 16. Further, the upper heat exchanger 4b is placed on the upper and lower partition plates 11. The rear edge of the outer periphery of the upper and lower partition plates 11 sandwiched between the heat exchangers 4a and 4b extends with a width that fits in the space between the vertical bars 14 of the protective net 13, and the diameter of the horizontal bars 15 of the protective net 13 is set to the inside. In this method, a plurality of hooking portions 17 are formed on the downward gutter by rolling in more than a semicircle. At the position of the hooking portion 17, the horizontal rail 15 at the center of the protective net 13 formed by welding the number wires as the vertical rails 14 and the horizontal rails 15 in a grid pattern is arranged. In order to protect the exposed fins of the heat exchangers 4a and 4b by holding the horizontal rails 15 in the center by the latching portions 17 of the upper and lower partition plates 11, the outer shell 9 of the rear opening of the housing 1 is protected. The protective net 13 is screwed onto the edge of the.
