It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
The existing courtyard machine is provided with a panel facing the ground, and the panel is provided with a return air inlet and an air outlet surrounding the return air inlet, namely the air outlet direction of the air outlet of the courtyard machine is downward inclined air outlet or even vertical downward air outlet, but when refrigerating, the air outlet of the air outlet is cold air, and the cold air at the moment can directly blow a human body to cause the problem of comfort reduction.
To this end, the present application provides a patio machine with an air supply duct, as shown in fig. 1 to 12, comprising: the air conditioner comprises a main body frame 10, wherein an air outlet duct 11 is formed in the main body frame 10; the air outlet assembly 20 is arranged on the main body frame 10 in a liftable manner, and a first air outlet 12 is formed between the air outlet assembly 20 and the main body frame 10 through descending; the air outlet assembly 20 is provided with at least one second air outlet 13, and the second air outlet 13 is communicated with the air outlet duct 11. Utilize first air outlet 12 to make the courtyard machine to the air-out of far away, realize the horizontal air-out even or the slope air-out that upwards goes out to overcome prior art well wind and blow out downwards and directly blow the human problem, set up the requirement that second air outlet 13 can make the courtyard machine satisfy the air-out of slope downwards even vertical air-out down simultaneously. And the cooperation through first air outlet 12 and second air outlet 13 can increase the air-out mode of courtyard machine to increase the air-out effect of courtyard machine and to the precision of temperature regulation and the speed of regulation.
It should be noted that the main body frame 10 is a main load-bearing structure of the courtyard machine, when the courtyard machine is installed, the main body frame 10 is installed on the ceiling, and other structures may be directly or indirectly installed on the main body frame 10 and fixed on the ceiling through the main body frame 10. The raise machine has the interior machine part of installing in the ceiling, and main body frame 10 is connected with interior machine, and air-out subassembly 20 is connected on main body frame 10, and interior machine has the interior machine air exit, and main body frame 10's air-out wind channel 11's first end and interior machine air exit intercommunication, air flow path: the air return inlet, the evaporator, the indoor unit air outlet, the first end of the air outlet duct 11, the second end of the air outlet duct, and the air outlet (the first air outlet 12 and/or the second air outlet 13) blow out.

The air flow in the air outlet duct 11 is guided by the air supply duct 14 and then blown out from the first air outlet 12, and the air supply duct 14 guides the vertically downward air flow in the air outlet duct 11 to be substantially far away from the courtyard unit along the horizontal direction, even to be blown out in the direction inclined upward relative to the horizontal plane, so that the horizontal air outlet to the courtyard unit is realized.
In the ceiling fan in the prior art, an air port is formed in the surface facing the ground to blow air, in order to change the air blowing direction, an air deflector is arranged at the air port to guide the air, but on the installation plane of the ceiling fan, the projection of the air deflector does not coincide with the projection of the panel of the ceiling fan, so that the air deflector has a poor guiding effect on the air flow, and finally the air blowing distance of the ceiling fan is reduced. When the projection of the air outlet assembly 20 is overlapped with the projection part of the frame 15, the air outlet assembly is substantially prolonged compared with the prior art, so that the flat blowing effect of the courtyard machine is good, the air supply distance is increased, when the courtyard machine opens the first air outlet 12, the air outlet assembly 20 is gradually far away from the main body frame 10 to form the air supply air duct 14, at the moment, the corresponding part of the air outlet assembly 20 forms the lower side surface of the air supply air duct 14, and when air flows through the air supply air duct 14, the air flows in the horizontal direction under the flow guide effect of the lower side surface of the air supply air duct, even blows out in the upward inclined direction, so that the air supply distance of the courtyard machine is increased, and the horizontal air outlet effect is realized.

Meanwhile, when the courtyard machine is in a shutdown state, the air outlet assembly 20 is attached to the main body frame 10, the corresponding part of the air outlet assembly 20 is attached to the frame 15, and when a person observes the courtyard machine from the ground, the person can only see the air outlet assembly 20 but cannot see the main body frame 10, so that the attractiveness of the courtyard machine is effectively improved.
As another embodiment, the projection of the air outlet assembly 20 exceeds the projection of the frame 15, in this case, compared with the case that the projection of the air outlet assembly 20 and the projection of the frame 15 are completely overlapped, the air outlet assembly can be further extended, so that the flat blowing effect and the air supply distance of the raise-level machine are further increased.
Preferably, the projection of the air outlet assembly 20 exceeds the projection of the main body frame 10, so that the air outlet assembly 20 effectively increases the air guide size relative to the prior art, and the purpose of increasing the air supply distance of the courtyard machine is achieved.
The air outlet assembly 20 is further provided with a guide plate 22, the guide plate 22 can form part of the air outlet duct 11 so that the inner surface of the air outlet duct 11 is smoother, or the guide plate 22 is located at a corner of the air outlet duct 11 and the air supply duct 14 so as to better guide the air flow in the air outlet duct 11 to the air supply duct 14.
The raise boring machine further comprises an air deflector 4, the air deflector 4 is rotatably arranged at the second air outlet 13, and the air deflector 4 can close or open the second air outlet 13.

In order to achieve the purpose that the refrigerating airflow does not blow people and blows far, considering the sedimentation characteristic of the refrigerating airflow and the general current situation that the hoisting height of a unit is higher than the height of a human body, the angle range of the included angle beta between the air outlet direction of the first air outlet 12 and the horizontal plane is-20 degrees and beta is not more than 45 degrees, when beta =0 degrees, the air outlet direction of the first air outlet 12 is parallel to the horizontal direction, and when beta is more than 0 degrees, the air outlet direction of the first air outlet 12 is inclined upwards relative to the horizontal plane. The air outlet direction of the first air outlet 12 refers to a main flowing direction of the airflow when the airflow flows out of the first air outlet, when the portion of the main body frame 10 and/or the air outlet assembly 20 for forming the air supply duct 14 is a plane, the air outlet direction of the first air outlet 12 is parallel to the plane, and when the portion of the main body frame 10 and/or the air outlet assembly 20 for forming the air supply duct 14 is a curved surface, the air outlet direction of the first air outlet 12 refers to a tangential direction of a position where the curved surface has the greatest influence on the airflow.

from the simulation result, it can be known that when L1 is 30mm, although the air volume does not reach the maximum value, both the cooling volume and the air supply distance are at the optimum level; when L1 is increased to 50mm, the air quantity and the refrigerating capacity start to increase, but the air supply distance starts to decrease; when L1 is continuously increased to 60mm, the air quantity and the refrigerating capacity are continuously increased, and the air supply distance is continuously reduced; when L1 is continuously increased to 61mm, although the air volume is increased, the increase rate begins to be reduced, and the refrigerating capacity is unchanged when compared with L1, namely 60mm, but the air supply distance is still continuously reduced, and the air supply distance is too small, the air speed is below 3m/s, and the comfort requirement of the courtyard machine cannot be met; when L1 is reduced to 20mm, the air quantity and the refrigerating capacity are reduced, and the air supply distance is increased; when L1 is continuously reduced to 15mm, the air quantity and the refrigerating capacity are further reduced, and the air supply distance is further increased; when L1 is continuously reduced to 14mm, the air quantity and the refrigerating capacity are still further reduced, the air supply distance is increased, the air quantity attenuation quantity is greater than 20%, the refrigerating capacity cannot ensure that the raise-level unit achieves the required heat exchange efficiency, and the energy-saving principle is not met. That is, only when L1 is in the range of 15mm to 60mm, the air quantity, the cooling capacity and the air supply distance of the raise machine can be matched to a reasonable state.
The air outlet assembly is provided with a first descending height L1, and the numerical range of the preset height L1 is that L1 is more than or equal to 20mm and less than or equal to 50mm.

From experimental results, when the D2/D1 is 0.8, the air quantity attenuation is less, and the air supply distance is far enough, so that the method is optimal; when the D2/D1 is increased to 0.85, the air volume begins to be increased, but the air supply distance is obviously shortened; when D2/D1 is continuously increased to 0.9, the air supply distance is seriously shortened and is unacceptable; when the D2/D1 is reduced to 0.75, the air volume begins to be reduced, and the air supply distance reaches the maximum value; when D2/D1 is continuously reduced to 0.7, the air quantity attenuation is serious and unacceptable. That is, under the condition that other conditions are not changed, the larger the width D2 of the second air outlet 13 is, the lower the outlet air speed is, and the more easily the wind is sucked by the return air inlet of the courtyard machine; conversely, the smaller the width D2 of the second outlet 13, the faster the air speed, the easier the air flow falls to the ground, and the less the influence on the air blowing distance, but the smaller the air volume, the less the heating effect cannot be ensured.
The air outlet assembly 20 comprises an air outlet frame, and the air outlet frame is lifted independently. In other embodiments, not shown, the air outlet assembly 20 includes an air outlet frame and a return air panel, the return air panel is provided with a return air inlet, and the air outlet frame and the return air panel are connected and lift together.
