Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning outdoor units, in particular to a heat dissipation structure of a central air-conditioning outdoor unit. Background Art

[0002] The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. This system is different from the traditional refrigerant air conditioning. It centrally processes air to meet comfort requirements. It uses the principle of liquid gasification refrigeration to provide the required cooling capacity for the air conditioning system to offset the cooling load of the indoor environment. The heating system provides the required heat for the air conditioning system to offset the heat load of the indoor environment. The central air conditioning outdoor unit is placed outdoors. The compressor in the outdoor unit compresses the gaseous Freon (or other types of refrigerants) into a high-temperature and high-pressure gas. This step increases the temperature and pressure of the refrigerant. The high-temperature and high-pressure gaseous refrigerant then flows to the condenser of the outdoor unit, where it dissipates heat and becomes a liquid at room temperature and high pressure. The outside air enters the outdoor unit from the air intake grilles set on the sides and back of the outdoor unit, and then contacts the heat dissipation fins on the condenser for heat exchange, and then is blown out by the exhaust fan. In order to prevent debris and particulate matter in the air from entering the outdoor unit, a dust net is often set at the air intake grille. After long-term use, the dust net will be blocked, resulting in poor air circulation. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-Figure 5 The utility model provides a technical solution: a heat dissipation structure of a central air-conditioning outdoor unit, comprising an air-conditioning outdoor unit main body 1, an air intake grille 2 is arranged on the back and left side of the air-conditioning outdoor unit main body 1, and a cleaning mechanism 4 is fixedly installed on the outer wall of the air-conditioning outdoor unit main body 1;

[0021] The cleaning mechanism 4 includes an L-shaped plate 401 and a motor 402. The L-shaped plate 401 is slidably sleeved on the air-conditioning outdoor unit body 1. The motor 402 is fixedly installed on the back of the air-conditioning outdoor unit body 1. A screw rod 403 is fixedly installed on the output end of the motor 402. A connecting block 404 is threadedly sleeved on the outer wall of the screw rod 403. A through groove is opened on the side of the L-shaped plate 401, and a rotating shaft 405 is rotatably connected to the inner wall of the through groove through a bearing. A cleaning brush 406 is fixedly installed on the outer wall of the rotating shaft 405. The edge of the cleaning brush 406 extends out of the through groove. The rotating shaft 405 is rotatably connected to the inner wall of the connecting block 404 through a bearing. The screw rod 403 is driven to rotate by the motor 402, so that the connecting block 404 moves up or down, thereby driving the rotating shaft 405 to move up or down. The movement of the rotating shaft 405 drives the cleaning brush 406 to move, so as to clean the air intake grille 2 to prevent dust and debris from clogging the air intake grille 2.

[0022] Two rotating shafts 405 are provided, and are respectively located in the through grooves in the two sides of the L-shaped plate 401, so as to clean the air intake grille 2 located on the back and left side of the air conditioner outer unit body 1. The cleaning brush 406 is a soft brush, so that the cleaning brush 406 can be squeezed and deformed and then extended into the air intake grille 2 to clean out dust and other debris in the air intake grille 2;

[0023] A gear 8 is fixedly mounted on the outer wall of the rotating shaft 405, and a rack 9 is meshed with the gear 8. The rack 9 is U-shaped and fixedly mounted on the outer wall of the air conditioner outer unit body 1. The gear 8 meshed with the rack 9 can drive the gear 8 to move up or down when the rotating shaft 405 moves up or down, so that the rack 9 pushes the gear 8 to rotate, thereby driving the rotating shaft 405 to rotate. The rotation of the rotating shaft 405 drives the cleaning brush 406 to rotate, so that the cleaning brush 406 rolls the air intake grille 2, thereby improving the cleaning effect of the cleaning brush 406 on the air intake grille 2;

[0024] The inner wall of the through groove on the L-shaped plate 401 is fixedly mounted with an inclined scraper 3, which faces the cleaning brush 406 and contacts the cleaning brush 406. The inclined scraper 3 is arranged so that when the rotating cleaning brush 406 contacts the inclined scraper 3, dust and other debris on the cleaning brush 406 will be scraped off by the inclined scraper 3, thereby preventing excessive dust and debris on the cleaning brush 406 from causing poor cleaning effect on the air intake grille 2.

[0025] The outer wall cover of the motor 402 has a protective cover 5, which is fixedly mounted on the outer wall of the air conditioner outer unit body 1 to protect the motor 402 and prevent the motor 402 from being eroded by rainwater;

[0026] A protective cover 3 7 is fixedly installed on the back of the air-conditioning outdoor unit body 1, and the protective cover 3 7 covers the connecting block 404 and the screw rod 403. A protective cover 2 6 is fixedly installed on the right outer wall of the air-conditioning outdoor unit body 1, and the protective cover 2 6 covers the gear 8 and the rack 9 on the right side to protect the gear 8, the rack 9, the connecting block 404 and the screw rod 403 to avoid being hit by falling objects from high altitude.

[0027] Working principle: During use, when the air intake grille 2 needs to be cleaned, the motor 402 is turned on to drive the screw 403 to rotate, so that the connecting block 404 moves up or down, and then drives the rotating shaft 405 to move up or down. The movement of the rotating shaft 405 drives the cleaning brush 406 to move, and the air intake grille 2 is cleaned. As the rotating shaft 405 moves up and down, it drives the gear 8 to move up and down, so that the rack 9 pushes the gear 8 to rotate, and then drives the rotating shaft 405 to rotate. The rotation of the rotating shaft 405 drives the cleaning brush 406 to rotate, so that the cleaning brush 406 rolls and brushes the air intake grille 2, thereby improving the cleaning effect of the cleaning brush 406 on the air intake grille 2.

[0028] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
