Background
At present, most wall-mounted units of indoor units of air conditioners adopt single through-flow blades, air return inlets of air conditioners are usually arranged at the top of a shell, and air supply outlets are arranged below the shell. The wall-mounted air conditioner has good air supply state and air flow organization, but because only one air outlet is arranged at a lower position, even if the air deflector is used for adjusting the air outlet angle, the blowing direction of cold air/warm air is limited to a smaller fan-shaped angle on a vertical surface. And because the wind pressure of the cross-flow fan blade is low, the air supply distance is limited, the area which can be quickly influenced by the whole cross-flow internal machine is only a fan-shaped area on the vertical surface of the air outlet, other areas need longer time to reach the preset temperature through convection heat transfer, and the heating/cooling speed is slow.

By controlling the starting and stopping of the two centrifugal impellers and the control of the rotating direction, double-opening large air supply or independently-opened upward refrigeration air supply or downward heating air supply is realized. The design of multi-directional air outlet expands the position of the air outlet, enlarges the air outlet range, and improves the comfort of air supply by controlling the air outlet direction. However, in the structural design of the above patent, the air inlets and the air outlets are all in front of the panel, obvious backflow can be formed during operation, and blown air flows flow into the fan again near the air inlet, which seriously affects the operation efficiency of the fan.

The patent shows the form of air inlet and outlet and backflow prevention, and the structure of the inlet and the outlet is not further explained.

As shown in the basic structural diagram of fig. 1, the present invention designs a centrifugal hanging machine with four air inlets at the back side and four air outlets at the front side of a multi-fan, which includes a first centrifugal impeller 21 and a second centrifugal impeller 22, four air inlets 5 at the back side and four air outlets 4 at the front side.

The control component 10 of the fan blade is arranged between the two centrifugal impellers, and comprises a control circuit, a motor and the like. The heat exchanger 3 is arranged behind the whole air duct system, and the air conditioner condensate water is enabled to vertically drop through the vertically-released heat exchanger 3 and cannot be leaked to an air duct area. A section of interval is reserved between the heat exchanger and the wall body to serve as an air inlet, and the design of a large air inlet with air inlet at the periphery is achieved.

And a diffusion outlet design is added at each air outlet position section, the volume of the cavity at the outlet position is increased, after the air flow is blown out from the centrifugal fan blade, the volume of the outlet cavity is increased, the air flow speed is reduced, the pressure is increased along with the reduction of the air flow speed, and the pressure of the air flow outlet is increased, so that the air outlet is smoother. Taking the first centrifugal impeller 21 on the left side and the air duct area as an example, the fan blade runs counterclockwise, the airflow flows out from the first upper air outlet 411, the first lower air outlet 421 and the first side air outlet 43 along with the molded line of the volute respectively, and a volute tongue for placing internal leakage is designed at the joint inside the outlet, so that the leakage loss is reduced.

The outlet airflow rapidly leaves the vicinity of the air conditioner under the guidance of the air deflector, avoids entering an air inlet area and is sucked into the internal machine for the second time, reduces the possibility of generating backflow, and avoids the efficiency reduction of the fan.
The whole implementation process is as follows: the control assembly 10 controls the whole starting and operation, the first centrifugal impeller 21 and the second centrifugal impeller 22 rotate, air is sucked by the air inlet 5 on the four sides, and air flow passes through the heat exchanger 3 to exchange heat with a refrigerant in the evaporator 3.

Meanwhile, the air deflector guides the outlet airflow to be far away from the air inlet area, so that the phenomenon that the outlet airflow flows back to the inlet in the common multi-surface air inlet and outlet air conditioner is avoided. Particularly, the pre-installed fixed plate 8 is pre-installed at the left and right air outlet positions of the inner machine, a user can decide whether to remove the pre-installed plate according to the installation and use positions so as to start the left and right air outlets, and meanwhile, the upper air deflector is installed, so that the air outlet loss caused by that the air is always blown to the wall when the inner machine is installed close to the corner is avoided in a detachable mode, and the wall is stained or the air outlet water vapor soaks the wall and the like.
The design of air inlets and front multi-region air outlets is integrally made at the back, so that the air conditioner has abundant air inlet amount and large air inlet amount, meanwhile, the multi-air outlet design can realize the temperature control coverage of multi-region large depth, and the state of each air outlet can be independently controlled to realize the customized heating/refrigerating requirement.
On the air duct for air outlet, the air flow thrown out by the rotation of the centrifugal fan blade directly enters the outlet position, and then is directionally adjusted by the air deflector, as shown in fig. 4-5. The large corner in the air duct in the common design is avoided, the air flow steering is small, and the energy loss is less.
