Referring to fig. 1, generally, an air conditioner includes an indoor heat exchanger 410, and an outdoor unit 100 of the air conditioner includes an outdoor heat exchanger 120, a compressor 110, and a throttling device 130, wherein the indoor heat exchanger 410, the compressor 110, the outdoor heat exchanger 120, and the throttling device 130 are sequentially connected by refrigerant pipes to form a refrigerant circulation loop. In the cooling mode, the indoor heat exchanger 410 serves as an evaporator and the outdoor heat exchanger 120 serves as a condenser. The gas refrigerant of the indoor heat exchanger 410 is sucked through the suction port of the compressor 110, compressed by the compressor 110, changed into a high-temperature and high-pressure gas refrigerant, and then introduced into the outdoor heat exchanger 120. The refrigerant exchanges heat with air in the outdoor environment in the outdoor heat exchanger 120, and the temperature of the refrigerant is lowered to become a liquid refrigerant. The liquid refrigerant is throttled by the throttling device 130 and enters the indoor heat exchanger 410, and is evaporated and absorbed in the indoor heat exchanger 410, so that the temperature of the indoor heat exchanger 410 is reduced. The evaporated gaseous refrigerant returns to the compressor 110 through the suction port of the compressor 110, and is circulated in such a manner as to transfer indoor heat to the outdoor, thereby reducing the temperature of the indoor environment. In the heating mode, the indoor heat exchanger 410 serves as a condenser, and the outdoor heat exchanger 120 serves as an evaporator. The refrigerant circulation direction is changed by reversing the four-way valve. The high-temperature and high-pressure gaseous refrigerant discharged from the compressor 110 enters the indoor heat exchanger 410, thereby increasing the temperature of the indoor heat exchanger 410. The refrigerant is reduced in temperature into a liquid refrigerant in the interior heat exchanger 410. The liquid refrigerant is throttled by the throttling device 130 and enters the outdoor evaporator, and is evaporated in the outdoor heat exchanger 120 by absorbing heat of the outdoor environment, and the evaporated gaseous refrigerant is sucked by the compressor 110, and is circulated in such a way to pump heat of the outdoor environment to the indoor space.
Referring to fig. 1 to 4, an outdoor unit 100 of an air conditioner according to an embodiment of the present disclosure includes a casing, an outdoor fan, a bracket 210, and a fresh air duct, wherein the casing is configured with a hollow inner cavity, and an air inlet and an air outlet communicated with the hollow inner cavity; the outdoor fan is arranged in the hollow inner cavity and used for driving air to flow from the air inlet to the air outlet; a bracket 210 fixed to the outdoor unit; fresh air pipe, first end are fixed in support 210, and the indoor environment is connected to the second end, and fresh air pipe's first end is towards the air outlet to air that blows off from the air outlet leads to indoor environment.
In the embodiment of the present disclosure, the outdoor unit 100 of the air conditioner includes a casing configured with a hollow inner chamber and an air inlet and an air outlet communicated with the hollow inner chamber. The outdoor heat exchanger 120 is located in the hollow interior cavity, as is the outdoor fan. The outdoor fan drives air to flow from the air inlet to the air outlet, and the outdoor air flows through the outdoor heat exchanger 120 to exchange heat with the outdoor heat exchanger 120. In the heating mode, the outdoor heat exchanger 120 serves as an evaporator, absorbs heat from air flowing through the outdoor heat exchanger 120, and pumps the absorbed heat to the indoor space through the refrigerant circulation system; in the cooling mode, the outdoor heat exchanger 120 functions as a condenser, and transfers its heat to the air passing through the outdoor heat exchanger 120. The outdoor fan is used to facilitate heat exchange between the outdoor heat exchanger 120 and the outdoor environment. The bracket 210 is used to fix the first end of the fresh air duct at a preset position, specifically, the first end of the fresh air duct faces the air outlet of the outdoor heat exchanger 120. When the outdoor fan is running, a part of the air blown out from the outdoor heat exchanger 120 enters the fresh air duct through the first end of the fresh air duct and enters the indoor environment along the fresh air duct, thereby realizing fresh air delivery. By using the outdoor unit 100 of the air conditioner provided by the embodiment of the present disclosure, the fresh air function is realized by using the outdoor fan, which is easy to realize, energy-saving and environment-friendly. Because the fan does not need to be arranged, the fan noise generated when the fresh air function is realized is avoided, and the user experience is improved.
Optionally, the outdoor unit 100 further includes an air outlet grille disposed at an air outlet of the outdoor unit 100; wherein, support 210 makes the first end of fresh air pipe apart from air-out grid first distance.
The air outlet grill is provided to improve safety of the outdoor unit 100. The first end of the fresh air duct faces the air outlet of the outdoor unit 100, and is inevitably shielded by the air outlet. The air outlet capacity of the outdoor unit 100 is reduced while the fresh air function is realized, and the heat exchange effect between the outdoor heat exchanger 120 and the outdoor environment is reduced. The first end of the fresh air duct is a first distance from the air outlet grille, and the original air outlet sectional area of the air outlet of the outdoor unit 100 can be maintained. When the outdoor unit 100 of the air conditioner is exhausting, a positive pressure area is formed in front of the air outlet of the outdoor unit 100 of the air conditioner, the first end of the fresh air pipe is a first distance away from the air outlet grid and still located in the positive pressure area, and the air blown out from the air outlet of the outdoor unit 100 of the air conditioner can still enter the indoor environment through the fresh air pipe 220. In addition, the air blown out by the outdoor unit 100 is opposite to the temperature required for current indoor environment temperature adjustment, specifically, when the cooling mode is operated, the outdoor unit 100 blows out hot air, and when the heating mode is operated, the outdoor unit 100 blows out cold air. Taking the cooling mode as an example, the hot air blown out by the outdoor unit 100 also exchanges heat with the outdoor environment, and the temperature thereof gradually decreases as the distance from the outlet increases. And the speed of heat exchange is positively correlated with the temperature difference. The first end of the fresh air duct is a first distance away from the air outlet grille, and the air volume blown out by the outdoor unit 100 of the air conditioner drops faster within the first distance. With this arrangement, the influence of the air blown into the outdoor unit on the indoor temperature can be reduced. The first distance is different for different air conditioners and different outdoor fan speeds, and in the disclosed embodiment, the first distance is 30-50 centimeters.
Optionally, the cross-sectional area of the first end of the fresh air duct gradually decreases along the air flow direction.
The first end of the fresh air pipe is funnel-shaped, and a reduced hole is formed. After the air enters the fresh air duct, the flow rate of the air is increased along with the reduction of the sectional area, which is beneficial to overcoming the on-way resistance of the fresh air duct 220 and better entering the indoor environment. The larger opening at the first end of the fresh air duct 220 allows more air to enter the fresh air duct.
Optionally, the outdoor unit 100 further includes a fresh air filter screen 230 disposed in the fresh air duct for filtering air passing through the fresh air duct.
The fresh air duct is provided with a fresh air filter screen 230 which can improve the quality of air entering the indoor environment through the fresh air duct. Because the filter screen can play certain throttling action to the new trend air inlet, in order to improve new trend air inlet rate, the number of 230 meshes of new trend filter screen here should not be too much. For example, the mesh size of the filter screen is 10-18 mesh.
Optionally, the outdoor unit 100 further includes an outdoor unit filter screen disposed at an air inlet of the outdoor unit 100.
The air inlet of the outdoor unit 100 is provided with an outdoor unit filter screen, so that the air entering the outdoor unit 100 is filtered on one hand, the air conditioning performance can be prevented from being affected by the heat exchange filth of the outdoor unit, on the other hand, the quality of the air blown out through the air outlet of the outdoor unit 100 is improved, and further, the quality of the fresh air entering the indoor heat exchanger 410 through the fresh air duct is improved.
Optionally, the outdoor unit 100 further includes a first valve 240 disposed in the fresh air duct for controlling a conducting state of the fresh air duct.
And the control of the on-state of the fresh air pipe comprises changing the on-off state and the opening degree of the fresh air pipe. When fresh air needs to be conveyed to the indoor environment, the first valve 240 is opened, and the air inlet volume of the fresh air is adjusted by adjusting the opening of the first valve 240. When no fresh air is required to be delivered, the first valve 240 is closed. The first valve 240 is provided, which is convenient for users to use.
Optionally, the first valve 240 is an electrically actuated valve.
The electric valve is arranged, so that the fresh air function can be opened and closed, and the fresh air quantity can be automatically controlled, and the use by a user is further facilitated.

Optionally, the outdoor unit 100 further includes a fresh air blower 250 disposed in the fresh air duct for driving air to flow from the first end to the second end of the fresh air duct.
The fresh air function is realized by the air outlet of the outdoor fan, and the fresh air is conveyed by the operation of the outdoor fan. When the air conditioner is not operated, the outdoor fan is in an inoperative state. In this case, the "fresh air only" function cannot be realized. If force outdoor fan to rotate, though can realize the new trend function, but outdoor fan power is great, and outdoor fan's power is not all used for realizing the new trend and carries, has caused the waste to the energy. The fresh air pipe 220 is provided with the fresh air fan 250, and the fresh air can be conveyed by the drive of the fresh air fan 250 in the fresh air mode, so that the functions of the outdoor unit 100 of the air conditioner are enriched, the energy is saved, the environment is protected, and the use by a user is facilitated.
Optionally, the outdoor unit 100 further includes an exhaust duct 310 having a first end facing the air inlet of the outdoor unit 100 and a second end connected to the indoor environment.
When fresh air pipe is to indoor air-conveying, the indoor environment is the malleation environment, and under this malleation, the indoor air outwards flows in order to maintain the pressure balance of interior external environment through door and window's gap. If the indoor environment leakproofness is good, carry the effect of new trend then corresponding relatively poor. The first end of the air exhaust duct 310 faces the air inlet of the outdoor unit 100, and when the fan of the outdoor unit 100 is running, the air inlet of the outdoor unit 100 is under negative pressure, and the air in the indoor environment is sucked out through the fresh air duct under the negative pressure. The indoor environment can be controlled to exchange air with the outdoor environment through the exhaust air duct 310 and the fresh air duct. The first end of the fresh air pipe is located in the positive pressure area of the air outlet of the outdoor unit 100, and the first end of the exhaust air pipe 310 is located in the positive pressure area of the air inlet of the outdoor unit 100, so that the circulation of indoor and outdoor air is promoted by utilizing the pressure difference between the two sides of the outdoor fan. By adopting the arrangement mode, the fresh air volume delivered to the room by the outdoor unit 100 of the air conditioner can be effectively improved. In addition, the air discharged from the exhaust duct 310 may improve the heat exchange capability of the outdoor heat exchanger 120. Specifically, when the air conditioner operates in the cooling mode, the outdoor heat exchanger 120 serves as a condenser and needs to be cooled. The indoor air discharged from the discharge air duct 310 has a temperature lower than the outdoor ambient temperature, and contacts the outdoor heat exchanger 120 to improve the cooling effect of the outdoor heat exchanger 120. The air conditioner operates in a heating mode, and the outdoor heat exchanger 120 serves as an evaporator, and itself needs to absorb heat. The indoor air temperature discharged by the air exhaust duct 310 is higher than the outdoor ambient temperature, and the indoor air contacts the outdoor heat exchanger 120 to provide heat for the evaporation of the refrigerant in the outdoor heat exchanger 120, so that the heat absorption effect of the outdoor heat exchanger 120 is improved. By adopting the design, the indoor air after being cooled or heated is recycled, and the energy-saving and environment-friendly effects are achieved.
Optionally, the outdoor unit 100 further includes a second valve 320 disposed in the discharge air duct 310 for controlling a conduction state of the discharge air duct 310.

When fresh air needs to be delivered to the indoor environment, the second valve 320 is opened, and the fresh air inlet amount is adjusted by adjusting the opening of the second valve 320. When fresh air delivery is not required, the second valve 320 is closed. The second valve 320 is provided to facilitate the user's use.
Optionally, the outdoor unit 100 further includes a discharge fan 330 disposed in the discharge air duct 310, wherein the discharge fan 330 is used for driving air to flow from the second end to the first end of the discharge air duct 310.
The fresh air function is realized by the air outlet of the outdoor fan, and the fresh air is conveyed by the operation of the outdoor fan. When the air conditioner is not operated, the outdoor fan is in an inoperative state. In this case, the "fresh air only" function cannot be realized. If force outdoor fan to rotate, though can realize the new trend function, but outdoor fan power is great, and outdoor fan's power is not all used for realizing the new trend and carries, has caused the waste to the energy. The exhaust duct is provided with an exhaust fan 330, and fresh air can be conveyed by means of the driving of the exhaust fan 330 in a fresh air only mode. Specifically, when the exhaust fan 330 operates, the indoor air is delivered to the outdoor, the indoor environment is called as a negative pressure environment, and the indoor environment sucks air into the indoor environment through a fresh air pipe or a gap between doors and windows, so that fresh air is delivered. The setting form enriches the functions of the outdoor unit 100 of the air conditioner, saves energy, protects environment and facilitates the use of users.
