The air supply assembly 4 in the embodiment of the present invention will be described in detail with reference to the drawings.
Referring to fig. 2 and 3, the air supply assembly 4 in the embodiment of the present invention includes: supply air ducts, baffles 45 and drive means. The duct body 41 of the air supply duct is a special pipe structure, and a first air inlet 40, a second air inlet 47 and an air outlet 46 are formed on the duct body. Specifically, the first intake vent 40 is square and formed at one end of the duct body 41, the second intake vent 47 is approximately square and formed at the middle of the duct body 41, the middle of the duct body 41 is formed in a flattened box-type structure to facilitate installation of the duct, and the structure of the duct body 41 can be adaptively adjusted according to an installation space.
Referring to fig. 3 and 4, the first air inlet 40 of the air supply duct extends to the surface of the outdoor unit of the air conditioner and communicates with the outdoor environment. Specifically, as shown in fig. 1, a square through hole is formed at the top end of the back plate 1, and a grill 3 is connected to the through hole, and the shape of the through hole matches the shape of the first air inlet 40. Alternatively, the through-hole may also be provided on the side plate 5 and connect the grill 3 to prevent foreign substances from entering into the air supply duct.
Referring to fig. 1 and 4, the second air inlet 47 extends to between the condenser 2 and the blower 7, and the heat sink 8 faces the air outlet 46 or is disposed downstream of the air supply duct, and the heat sink 8 in this embodiment is disposed downstream of the air supply duct. The baffle 45 is pivotally connected to the second air inlet 47, the baffle 45 can completely block the second air inlet 47, the baffle 45 is pivotally connected to the duct body 41 through the rotating shaft 44, as shown in fig. 2, the baffle 45 is in a state of closing the second air inlet 47, and when the baffle 45 closes the second air inlet 47, the air supply duct opens an air flow path from the first air inlet 40 to the air outlet 46. As shown in fig. 3, the baffle 45 is in a state of opening the second air inlet 47, and when the baffle 45 opens the second air inlet 47, the air supply duct opens the air flow path from the second air inlet 47 to the air outlet 46.
In addition, the air supply assembly 4 further comprises a motor 42 for driving the baffle 45 to swing. The motor 42 is connected with the computer board 6 and controlled by the computer board 6.
Preferably, the second air inlet 47 is opposite to the air outlet 46, so that the air flow can be smoother. Since the duct body 41 has a flattened box-shaped structure, although the air flow path from the first air inlet 40 to the air outlet 46 is still open, since there is no obstruction in the straight-tube-shaped air flow path from the second air inlet 47 to the air outlet 46, when the second air inlet 47 is open, the air flow path from the second air inlet 47 to the air outlet 46 becomes the main air flow path, and most of the air flow is transmitted to the heat sink 8 through the path.

For example, a fan is installed adjacent to the first air inlet 40, and the fan rotates to draw outdoor air into the air duct, thereby promoting air circulation in the air duct.
The following describes a control method of the air supply assembly 4 for the outdoor unit of the air conditioner based on the outdoor unit of the air conditioner provided in the above embodiment, and with reference to fig. 4 and 5, the control method of the air supply assembly 4 for the outdoor unit of the air conditioner includes:
and S1, detecting the operation mode of the air conditioner. Specifically, there are two operation modes of the air conditioner: the specific working mode is selected by a user, for example, the user selects the air conditioner running mode to be the cooling mode through a remote controller or a mobile terminal of intelligent equipment, and the computer board 6 of the air conditioner can know the selection, so that the working mode corresponding to the running of the air conditioner can be started.
And S2, selectively controlling the action of the baffle 45 according to the detection result.
Specifically, if the operation mode is the cooling mode, the control flap 45 swings to or maintains a state of closing the second air inlet 47 to connect the air flow path from the first air inlet 40 to the air outlet 46, as shown in fig. 5. The specific working principle is as follows: when the air conditioner is refrigerating, the refrigerant circulating in the air conditioner takes away indoor heat and then circulates to the outdoor unit, exchanges heat with outdoor air in the condenser 2, transfers the heat carried in the refrigerant to the air, thus, the temperature of the air passing through the condenser 2 is increased, which is not beneficial to the heat dissipation of the heat sink 8, at this time, the second air inlet 47 is blocked by the control baffle 45, the air flowing through the condenser 2 can not directly pass through the heat sink 8, at this time, because the first air inlet 40 is communicated with the outdoor environment, under the action of the air guide member such as a small fan, low-temperature outdoor air (relative to high-temperature air after heat exchange with the condenser 2) enters the air duct through the first air inlet 40 to exchange heat with the heat dissipation fins 8, the path of the outdoor air entering the air supply assembly is shown by a dotted arrow in fig. 5, and the air supply pipeline conveys the outdoor air to the heat dissipation fins 8 so as to take away heat of the heat dissipation fins 8.
If the operation mode is the heating mode, the control flap 45 swings to or keeps in a state of opening the second air inlet 47 to connect the air flow path from the second air inlet 47 to the air outlet 46. Specifically, when the air conditioner heats, the temperature of the air flowing through the condenser 2 is reduced, the low-temperature air is favorable for heat dissipation of the heat dissipation fins 8, at this time, the second air inlet 47 is opened, the low-temperature air quickly takes away the heat of the heat dissipation fins 8, and the temperature of the computer board 6 is reduced, and a flow path of the low-temperature air is shown by a solid arrow in fig. 4.
The utility model provides an air supply component of air conditioner outdoor unit, through set up two air intakes in the supply air duct, with one of them air intake and outdoor environment intercommunication, in order to receive the air current in the outdoor environment, another air intake extends to between condenser and the fan, in order to receive the air current after the heat transfer with the condenser, and through setting up the baffle to selectively open or close different air intakes in order to put through different air current passageways, thereby can utilize the air current after the condenser cooling to carry out the heat exchange with the fin when the air conditioner heats, can prevent the air current after the condenser heats from getting into the fin clearance when the air conditioner refrigerates, and carry the low temperature air in the environment to the fin through the wind channel of putting through in order to cool down the fin, can make the radiating process of computer board in the outdoor unit not influenced by air conditioner mode and keep stable radiating effect like this, the problem of unbalanced heat dissipation of the computer board is avoided, the phenomenon that the air conditioner is shut down due to overheating of the computer board is further avoided, and meanwhile the service life of the computer board can be prolonged.
So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
