Description

Outdoor unit and air conditioner having same

technical field

The invention relates to the field of air conditioning equipment, in particular to an outdoor unit and an air conditioner with the same.

Background technique

At present, as buildings have higher and higher requirements for beauty and noise, in urban buildings, more and more buildings reserve built-in space (such as the space under the bay window) for the external unit of the air conditioner (that is, the air conditioner's outdoor unit) for installation. Usually, three sides of this kind of space are architectural entities, and one side is a beautification grille, and the space is limited.

If the outdoor unit is a small one with a single fan, it can barely fit into the space, but generally the air outlet faces outward and the air inlet faces the wall. This installation method of the outdoor unit results in a relatively narrow air inlet. If the installation is not done properly, it is easy to cause a short circuit of part of the airflow in a relatively sealed environment, and there is a problem of poor heat exchange effect. In addition, for household central air conditioners, generally a large outdoor unit needs to be configured, and an outdoor unit with a double-blade fan is required, which cannot be installed in this kind of building at all.

There is also an air conditioner in the prior art, the housing of which includes: a housing body and an avoidance part, the avoidance part is arranged on the side wall of the housing body, the outer wall of the avoidance part protrudes from the outer wall of the housing body, and the avoidance part The inner wall of the fan forms a concave structure to avoid the fan blades of the fan. When the thickness of the fan blades of the air conditioner is reduced, the diameter of the fan blades is increased to expand the coverage area of the fan blades, so as to ensure the air supply volume of the fan and meet the predetermined heat exchange efficiency requirements of the outdoor unit. The outdoor unit of this structure enters the air from the lower side and the upper side leaves the air. For the building, it is easy to heat (during cooling) or cool (during heating) the building maintenance structure, but instead increases the building load.

There is also an outdoor unit of an embedded air conditioner in the prior art. It can provide an effective installation structure for the installation of outdoor units whose capacity increases as the air conditioning capacity of the built-in air conditioner increases. The embedded outdoor unit is fixedly installed inside the rectangular space formed on the outer wall of the building, and can be divided into a suction area and a discharge area. Each area is equipped with multiple louver blades, and can be inhaled through the gaps between the louver blades. and the louver frame that discharges air; and the bottom surface that is fixedly installed in the interior of the building close to the louver frame, and the side facing the suction area and the discharge area on the louver frame is open and the other side is closed, and there is installed in it. A compressor that compresses the gaseous refrigerant supplied by the refrigerant pipe, an air-cooled condenser that condenses the gaseous refrigerant supplied by the compressor, and an air-cooled condenser that supplies external air to the air-cooled condenser through the suction area, and passes the heat-exchanged air through The outdoor unit housing for the cooling fan that discharges from the discharge area. The fan with this structure is installed on the upper part of the heat exchanger. If it is used in a space with a low height, the capacity of the unit will be greatly limited; the direction of the air inlet and outlet louvers is the same, which is not conducive to the organization of air flow.
