Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to an outdoor unit of an air conditioner.
Background
An outdoor unit of an air conditioner generally includes an axial flow fan and a heat exchanger, wherein the axial flow fan is disposed at the front and the heat exchanger is disposed at the rear. Therefore, certain space is required to be reserved around the outdoor unit of the air conditioner during installation so as to ensure that enough fresh air at normal temperature can pass through the heat exchanger and exchange heat with the heat exchanger. For example, chinese patent document (CN 201611257279.7) discloses an outdoor unit of a multi-split air conditioner, which adopts a back-side air inlet mode and a front-side air outlet mode, and in order to ensure normal operation, the back side of the outdoor unit cannot be attached to a wall, and a certain space needs to be reserved.
However, it is found that newly developed building sets have less and less installation space for outdoor units of central air conditioners by studying the architectural features of our country in recent years, and thus, most of the existing outdoor units of air conditioners are more and more difficult to adapt.
In order to overcome the above problems, chinese patent document (CN 201811296479.2) discloses an outdoor unit of an air conditioner, which includes a casing, a cavity is disposed in the casing, an air outlet is disposed on the front surface of the casing, and an air inlet is disposed on the side surface of the casing. The air conditioner outdoor unit changes the existing back air inlet and front air outlet modes into the left and right side air inlet and front air outlet modes, thereby solving the problem that the air inlet is influenced by the fact that the back is attached to the wall because the installation space is reduced.
However, when the outdoor unit of the air conditioner is installed, a certain space still needs to be reserved at two sides, and the three remaining sides except the front side cannot be tightly attached to the wall, so that the required installation space is still large, and the installation requirements of newly developed buildings cannot be fundamentally met.
