After the fresh air fan 400 is disposed in the casing 100 of the outdoor unit structure of the air conditioner, the casing 100 can protect the fresh air fan 400.
It should be understood that the outdoor unit of the air conditioner is disposed outdoors, and therefore the driving portion 200 drives the fresh air fan 400 to rotate, and then the fresh air fan sucks outdoor air into the casing 100, and inputs the outdoor air into the room through the fresh air inlet 140 and the fresh air pipe, so that the outdoor fresh air is input into the room, and the outdoor unit of the air conditioner has a fresh air function.

The fresh air fan 400 is also arranged in the casing 100, so that the casing 100 can protect the fresh air fan 400, the reliability of the outdoor unit of the air conditioner is better, the fresh air fan 400 can rotate in the casing 100 to more efficiently discharge heat or cold air in the casing 100 to the outside of the casing 100, and the refrigeration and heating performance of the air conditioner using the outdoor unit of the air conditioner is better.
In some embodiments, referring to fig. 3, in order to make the fresh air fan 400 and the heat dissipation fan 300 of the present application more efficient to suck the air outside the casing 100, the driving portion 200 may be configured to drive the fresh air fan 400 to rotate and then suck the air outside the casing 100 through the air inlet 120 of the casing 100, so that the fresh air fan 400 and the heat dissipation fan 300 can intake air from the same side, and thus the air outside the casing 100 can more efficiently pass through the air inlet 120 of the casing 100.
Specifically, the air inlet 120 of the casing 100 may be disposed at one side of the air inlet side of the fresh air fan 400, so that the air inlet side of the fresh air fan 400 can suck the air outside the casing 100 through the air inlet 120 of the casing 100 after the fresh air fan 400 rotates, and of course, the air inlet 120 of the casing 100 is also disposed at one side of the air inlet side of the heat dissipation fan 300, so that the heat dissipation fan 300 can efficiently suck the air outside the casing 100 into the casing 100 through the air inlet 120 of the casing 100. After the fresh air fan 400 and the cooling fan 300 enter air from the same side, the driving portion 200 drives the fresh air fan 400 and the cooling fan 300 to rotate simultaneously, and then the air outside the casing 100 can be sucked through the air inlet 120 of the casing 100, so that the flow of the air flow entering the casing 100 through the air inlet 120 of the casing 100 outside the casing 100 is larger, and the cooling and heating performance of the air conditioner using the air conditioner external unit of the application and the ventilation efficiency of the fresh air function are improved.
In some embodiments, referring to fig. 1 and 3, in order to make the internal structure of the outdoor unit of the present application more compact, so that the overall structure of the outdoor unit of the present application may be more compact, the fresh air fan 400 and the heat dissipation fan 300 of the present application may be coaxially disposed. Specifically, the driving portion 200 may adopt a motor having a rotating shaft, and the fresh air fan 400 and the heat dissipation fan 300 are both connected to the driving portion 200 to rotate, so that the fresh air fan and the heat dissipation fan 300 are coaxially disposed, and thus the fresh air fan 400 and the heat dissipation fan 300 are opposite to each other, thereby achieving the purpose of saving spaces on two sides of the rotating shaft of the driving portion 200 in the housing 100.
In addition, it should be noted that, when the fresh air fan 400 and the heat dissipation fan 300 are coaxially disposed on the rotating shaft of the motor, and the fresh air fan 400 and the heat dissipation fan 300 both draw in air outside the housing 100 through the air inlet 120 of the housing 100, the air inlet side of the fresh air fan 400 and the air inlet side of the heat dissipation fan 300 are disposed on the same side, so that the wind power generated by the rotation of the fresh air fan 400 and the wind power generated by the rotation of the heat dissipation fan 300 can be mutually accelerated to further increase the rotation speeds of the fresh air fan 400 and the heat dissipation fan 300, and thus the flow rate and the strength of the airflow entering the inner cavity 110 of the housing 100 through the air inlet 120 of the housing 100 are greater, so that the flow rate of the fresh air input into the room through the fresh air inlet 140 of the housing 100 is greater, so as to increase the ventilation efficiency of the indoor air, and the airflow input into the housing 100 can more efficiently discharge the heat or cold air dissipated by the condenser through the air outlet 130 of the housing 100.
Of course, in other embodiments, the new air fan 400 and the heat dissipation fan 300 of the present application may be disposed in different axes, specifically, one of the heat dissipation fan 300 and the new air fan 400 may be connected to the rotation shaft of the driving portion 200, and a transmission rotation shaft is disposed on one side of the rotation shaft of the driving portion 200, the other of the heat dissipation fan 300 and the new air fan 400 may be connected to the transmission rotation shaft, and the transmission rotation shaft of the driving portion 200 may be connected to the transmission rotation shaft in a gear-matching manner, so that the rotation shaft of the driving portion 200 may drive the transmission rotation shaft to rotate, thereby achieving the purpose that the new air fan 400 and the heat dissipation fan 300 are both driven to rotate by the driving portion 200 under the condition that the new air fan 400 and the heat dissipation fan 300 are different axes.
Specifically, the gears can be disposed on the rotating shaft and the transmission rotating shaft of the driving portion 200, the rotating shaft of the driving portion 200 can drive the transmission rotating shaft to rotate in a gear transmission manner, and of course, belt pulleys can be disposed on the rotating shaft and the transmission rotating shaft of the driving portion 200, and the rotating shaft of the driving portion 200 can drive the transmission rotating shaft to rotate in a belt transmission manner.
Still can set up reduction gears and clutching mechanism between the pivot of drive division 200 and the transmission pivot to the rotational speed that makes the pivot of drive division 200 and transmission pivot can be different rotates, perhaps makes the pivot of drive division 200 and the alternative rotation of transmission pivot, and new trend fan 400 is connected with the transmission pivot, thereby makes new trend fan 400's rotational speed adjustable. Specifically, when the indoor temperature is high, the indoor temperature can be reduced faster by reducing the cooling temperature of the air conditioner, accordingly, the power of the compressor of the air conditioner is relatively high, and the rotation speed of the cooling fan 300 is relatively faster, but in order to reduce the indoor temperature quickly, the rotation speed of the fresh air fan 400 can be reduced to reduce the ventilation efficiency of the indoor air, so that the indoor temperature reduction efficiency can be faster. Therefore, the fresh air fan 400 can be freely adjusted by arranging the speed reducing mechanism so as to adapt to various indoor environments.
Of course, the new air fan 400 may not rotate when the heat dissipation fan 300 rotates by the clutch mechanism.
In addition, in other embodiments, a dual-shaft motor may be further used as the driving portion 200 of the present application, such that the driving portion 200 has two rotating shafts, and the two rotating shafts of the driving portion 200 are located at two opposite sides of the driving portion 200, and the fresh air fan 400 and the heat dissipation fan 300 may be respectively connected to the two rotating shafts of the driving portion 200, so that the driving portion 200 may drive the fresh air fan 400 and the heat dissipation fan 300 to rotate.
In some embodiments, referring to fig. 3, in order to enable the heat dissipation fan 300 to more efficiently suck the air outside the housing 100 through the air inlet 120 of the housing 100, the air inlet side of the heat dissipation fan 300 may be disposed opposite to the air inlet 120 of the housing 100, so that the force generated by the rotation of the heat dissipation fan 300 can directly act on the air outside the housing 100 through the air inlet 120 of the housing 100, so that the air outside the housing 100 can more efficiently enter the housing 100 through the air inlet 120 of the housing 100. The fresh air fan 400 may also be disposed opposite to the air inlet 120 of the housing 100, such that an acting force generated by the rotation of the fresh air fan 400 may directly act on the air outside the housing 100 through the air inlet 120 of the housing 100, so that the air outside the housing 100 may enter the housing 100 through the air inlet 120 of the housing 100 more efficiently.
The air outlet 130 and the air inlet 120 of the housing 100 of the present application may be disposed opposite to each other, so that the air inlet 120 and the air outlet 130 of the housing 100 may have a convection structure, and accordingly, the air outlet side of the heat dissipation fan 300 is disposed opposite to the air outlet 130 of the housing 100, so that the heat dissipation fan 300 may more efficiently discharge the hot gas or the cold gas in the inner cavity 110 of the housing 100 to the outside of the housing 100 through the air outlet 130 of the housing 100. The air outlet side of the fresh air fan 400 may be disposed opposite to the fresh air inlet 140 of the casing 100, so that the air flow discharged from the fresh air fan 400 may be more efficiently input into the room through the fresh air inlet 140 of the casing 100, thereby improving the ventilation efficiency of the indoor air.
In addition, the opening of the fresh air inlet 140 of the housing 100 of the present application may be oriented to intersect with the orientation of the air inlet 120 of the housing 100, such that the fresh air inlet 140 and the air inlet 120 of the housing 100 are in a non-opposite state, i.e., the fresh air inlet 140 and the air outlet 130 of the housing 100 are disposed at different positions of the housing 100, such that the openings of the fresh air inlet 140 and the air outlet 130 disposed on the housing 100 may be relatively larger.
It should be understood that, when the opening area of the air outlet 130 of the housing 100 is larger, the flow rate of the gas exhausted through the air outlet 130 of the housing 100 can be larger, and thus the gas in the housing 100 can be exhausted through the air outlet 130 of the housing 100 more efficiently. When the opening area of the fresh air port 140 of the casing 100 is larger, the flow rate of the gas inputted into the room through the fresh air port 140 of the casing 100 can be made larger, thereby making the ventilation efficiency in the room higher.
Therefore, in particular, the inlet 120 and the outlet 130 of the casing 100 may be disposed on opposite side walls of the casing 100, and the fresh air inlet 140 of the casing 100 may be disposed on the top or the bottom of the casing 100, so that the inlet 120, the outlet 130 and the fresh air inlet 140 of the casing 100 are opened at different positions of the casing 100, and thus the inlet 120, the outlet 130 and the fresh air inlet 140 of the casing 100 do not interfere with each other, so that the inlet 120, the outlet 130 and the fresh air inlet 140 of the casing 100 may be disposed relatively larger.
It should also be understood that when the fresh air inlet 140 of the housing 100 is disposed at the top of the housing 100 and the air inlet 120 of the housing 100 is disposed on the side wall of the housing 100, the fresh air fan 400 may be a centrifugal fan, such that the axial direction, i.e., the air inlet side, of the fresh air fan 400 may face the air inlet 120 of the housing 100 and the radial direction, i.e., the air outlet side, of the fresh air fan 400 may face the fresh air inlet 140 of the housing 100.
In some embodiments, referring to fig. 1 and 3, when the heat dissipation fan 300 and the fresh air fan 400 are both connected to the rotation shaft of the driving portion 200, they may be disposed in the directions of the air inlet 120 and the air outlet 130 of the housing 100, and the heat dissipation fan 300 and the fresh air fan 400 are disposed in sequence. Specifically, the heat dissipation fan 300 is disposed inside the casing 100 and adjacent to the air inlet 120 of the casing 100, and the fresh air fan 400 is disposed inside the casing 100 and adjacent to the air outlet 130 of the casing 100, that is, the air inlet side of the fresh air fan 400 is located at the air outlet side of the heat dissipation fan 300, so that the airflow generated by the heat dissipation fan 300 can act on the air inlet side of the fresh air fan 400, and thus the fresh air fan 400 can suck more sufficient airflow and input the airflow into the room through the fresh air inlet 140 of the casing 100, thereby improving the indoor ventilation efficiency.
Of course, in other embodiments, the fresh air fan 400 may be disposed in sequence with the heat dissipation fan 300 in the direction from the air inlet 120 to the air outlet 130 of the housing 100. Specifically, the heat dissipation fan 300 is disposed inside the casing 100 at a side close to the air outlet 130 of the casing 100, the fresh air fan 400 is disposed inside the casing 100 at a side close to the air inlet 120 of the casing 100, and when the direction of the fresh air inlet 140 of the casing 100 is crossed with the direction of the air inlet 120 and the air outlet side of the fresh air fan 400 is toward the fresh air inlet 140 of the casing 100, the fresh air fan 400 can suck air outside the casing 100 and then discharge the air into the room through the fresh air inlet 140 of the casing 100 without passing through the heat dissipation fan 300, thereby preventing the condenser inside the casing 100 from affecting the air output by the fresh air fan 400 too much.
It should be understood that, when the air conditioner is in the cooling mode, the condenser will radiate heat to raise the temperature in the casing 100, and by disposing the fresh air fan 400 adjacent to the air inlet 120 of the casing 100 relative to the heat dissipating fan 300, the air input into the room by the fresh air fan 400 is less affected by the heat radiated by the condenser in the casing 100, so that the temperature of the air input into the room by the fresh air fan 400 is not too high, and the influence on the indoor temperature is reduced, and thus the indoor temperature can be maintained to be lower.
The air conditioner is in the mode of heating, and the temperature of condenser is lower, can make the temperature in the casing 100 lower, through setting up new trend fan 400 to the air intake 120 that is close to casing 100 relative radiator fan 300, can make new trend fan 400 input to indoor air receive the influence of the low temperature environment in the casing 100 less, and the temperature of new trend fan 400 input to indoor air can not be too low like this to reduce the influence to indoor temperature, thereby make indoor can maintain higher temperature.
In some embodiments, referring to fig. 3, in order to reduce the influence of the airflow generated by the heat dissipation fan 300 and exhausted from the air outlet side on the fresh air fan 400 when the fresh air fan 400 is disposed on the air outlet side of the heat dissipation fan 300, the fresh air fan 400 may be disposed to form a projection area on the heat dissipation fan 300 in the direction from the air outlet 130 to the air inlet 120 of the housing 100, and the projection area is located in the middle of the heat dissipation fan 300.
