Referring to fig. 1, 3 and 6, in the present embodiment, an indoor unit of an air conditioner includes a housing 100 and an air guide assembly. The casing 100 is provided with an air outlet 120 extending along the length direction thereof, and the air outlet 120 comprises an air supply section 121 positioned at the downstream of the air supply duct 110 and a shielding section 122 positioned at one end of the air supply section 121 and shielded by an internal part 800 of the indoor unit of the air conditioner; the air guide assembly includes an air guide plate 200, a drainage member 300, and a driving mechanism 400. The air deflector 200 is rotatably arranged at the air outlet 120, and a containing part 210 is arranged on the side surface of the air deflector 200; the drainage member 300 is disposed in the accommodating portion 210, the drainage member 300 has a first state protruding from a side surface of the air deflector 200 and a second state accommodated in the accommodating portion 210, and the drainage member 300 is configured to guide the air-out airflow to flow through a portion of the air deflector 200 corresponding to the shielding section 122 in the first state; the driving mechanism 400 is disposed on the air deflector 200, and the driving mechanism 400 is used for driving the drainage member 300 to be in the first state or the second state.
Because the air conditioner of the embodiment has the drainage member 300 which can guide the air outlet airflow to flow through the part of the air deflector 200 corresponding to the shielding section 122, the temperature distribution on the air deflector 200 can be uniform in the operation refrigeration mode of the indoor unit of the air conditioner, so that no normal-temperature wet air exists in the part of the air deflector 200 corresponding to the shielding section 122, and the condition that cold air and hot air on the air deflector 200 are intersected is effectively avoided. Therefore, the air conditioner of the present embodiment can effectively restrict the generation of condensed water on the air deflector 200. In addition, since the drainage member 300 in the indoor unit of the air conditioner of the embodiment can be further accommodated in the accommodating portion 210 by being driven by the driven mechanism 400, when the condensed water on the air deflector 200 is not required to be limited, or when the indoor unit of the air conditioner operates in a heating mode or other modes, the drainage member 300 does not interfere with the flow direction and the flow rate of the air outlet air flow of the indoor unit of the air conditioner, so that the normal operation of the indoor unit of the air conditioner is ensured.
In the prior art, in order to avoid that condensed water is not generated on the air deflector 200, the air deflector 200 is directly placed in the air duct, and the method can avoid that the air deflector 200 is exposed, but because the air outlet of the false air port is not generated, the false air port (for example, a shell for wrapping an electric control component and the side wall of the false air port) still has a normal-temperature wet air area, and the air supply area of the air supply port and the false air port still have cold and hot air to be intersected, and still have the risk of condensation. In addition, the air guide plate 200 is built in the air duct, and resistance to the air quantity in the air duct increases.
In addition, when the indoor unit of the air conditioner is used for a long time, dust (for example, a casing for wrapping an electric control part and a side wall of the pseudo-air inlet) is accumulated when no air flows out of the pseudo-air inlet, and even if the air deflector 200 is built into an air duct, the defect cannot be overcome.
Referring to fig. 1, 2, 3 and 4, in the present embodiment, one end of the drainage member 300 extends to a portion corresponding to the air supply section 121 toward the air inlet end of the air guide plate 200, and the other end of the drainage member 300 extends to a portion corresponding to the shielding section 122 toward the air inlet end of the air guide plate 200, and the middle portion of the drainage member 300 protrudes toward the air outlet end of the air guide plate 200, and the drainage member 300 is further used to guide the air outlet flow to the inner part 800 in the first state.
Because the air conditioner indoor unit of the embodiment is provided with the shape structure or the extending direction of the drainage member 300, the drainage member 300 can guide the air outlet flow to the inner component 800 of the air conditioner indoor unit, so that the air outlet flow can flow through the shielding section 122, and the normal-temperature wet air in the shielding section 122 is blown away, so that the temperature of the whole air outlet 120 is uniform and no cold-hot air is intersected. Therefore, the indoor unit of the air conditioner of the present embodiment effectively restricts the generation of condensed water at the shielding section 122. Meanwhile, the air outlet air flow flows through the shielding section 122, accumulated dust at the shielding position can be blown away, the function of dust removal and cleaning is achieved, and the convenience in use of the indoor unit of the air conditioner is guaranteed. And, the flow of the inner air flow of the air supply duct 110 is not influenced, and wind resistance is generated on the air flow of the air outlet.
Referring to fig. 8, in the present embodiment, the air conditioner indoor unit further includes an air blowing fan 500 and a dust sensor 600. The air supply fan 500 is disposed in the housing 100; the dust sensor 600 is connected to the blower fan 500 and the driving mechanism 400, and the dust sensor 600 is used for acquiring the accumulation amount of dust at the shielding section 122; and, the driving mechanism 400 is configured to: in the case where the accumulation amount is equal to or larger than the predetermined value, the drainage member 300 is driven to be in the first state; in the case where the accumulation amount is smaller than the predetermined value, the drainage member 300 is driven in the second state; and, the blower fan 500 is configured to: when the accumulation amount is equal to or greater than the predetermined value, the rotational speed of the blower 500 is a first rotational speed value; when the accumulation amount is smaller than the predetermined value, the rotation speed of the blower 500 is a second rotation speed value; wherein the first rotational speed value is greater than the second rotational speed value.
It will be appreciated that the dust sensor 600 may be connected to the blower 500 and the drive mechanism 400 in electrical communication via the controller 900. And the operation of the driving mechanism 400 and the blower fan 500 may be controlled by the controller 900. And further, the state of the drainage member 300 can be switched, and the rotation speed of the air blower 500 can be adjusted. In addition, referring to fig. 1, 2, 3 and 4, in the first state of the drainage member 300, the accumulated dust at the shielding position can be blown away, so that the function of dust removal and cleaning is achieved, and meanwhile, the rotating speed of the air supply fan 500 is increased, and the cleaning effect of the air conditioner indoor unit on the dust at the shielding section 122 is further improved. Meanwhile, other functions or modes of the air conditioner indoor unit are ensured to run when the ash cleaning function is not needed.
Referring to fig. 1, 2, 3 and 4, in the present embodiment, the drainage member 300 is a curved arc-shaped structure. And further, in the process that the air outlet flow flows through the flow guiding surface of the flow guiding member 300, smaller wind loss of the air outlet flow can be ensured, and the effect of limiting the condensed water at the positions of the air deflector 200 and the shielding section 122 and the cleaning effect of dust at the position of the shielding section 122 are ensured.
Referring to fig. 1, 2, 3 and 4, in the present embodiment, the portion of the drainage member 300 corresponding to the air blowing section 121 is bent to a greater extent than the portion of the drainage member 300 corresponding to the shielding section 122.
It should be understood that, when the air-out airflow flows from the air supply duct 110 to the drainage member 300, the included angle between the flow direction of the air-out airflow and the drainage member 300 may affect the resistance of the air-out airflow. The portion of the flow guiding member 300 corresponding to the air supply section 121 has a larger bending degree, so that the flow direction of the air outlet airflow is kept consistent before and after the air outlet airflow flows through the flow guiding surface of the flow guiding member 300 as much as possible, and the air loss of the air outlet airflow when the air outlet airflow flows into the flow guiding member 300 is reduced. In addition, the wind resistance of the drainage member 300 is also received during the process of changing the flow direction of the air-out airflow flowing through the drainage member 300. The portion of the drainage member 300 corresponding to the shielding section 122 has a smaller bending degree, so that the flowing direction of the air-out airflow can be changed slowly as much as possible, and the air loss when the air-out airflow flows through the drainage member 300 is reduced. Therefore, the bending degree of the portion of the drainage member 300 corresponding to the air supply section 121 is greater than that of the portion of the drainage member 300 corresponding to the shielding section 122, so that the flow rate of the air-out air flow flowing through the portion of the air guide plate 200 corresponding to the shielding section 122 and through the shielding section 122 or to the inner member 800 can be ensured, and further, the effect of restricting the generation of condensed water at the air guide plate 200 and the shielding section 122 and the cleaning effect of dust at the shielding section 122 can be ensured.
Referring to fig. 5 and 6, in the present embodiment, the accommodating portion 210 is an accommodating hole that communicates the inner side surface of the air guide plate 200 and the outer side surface of the air guide plate 200; the drainage member 300 includes a first drainage plate 310 and a second drainage plate 320, the first drainage plate 310 having a state of protruding from the inner side surface of the air guide plate 200 and a state of being accommodated in the accommodating portion 210; the second flow guiding plate 320 has a state protruding from the outer surface of the air guiding plate 200 and is accommodated in the accommodating portion 210.
The two drainage members 300 are arranged, in the first state of the drainage member 300, the inner side surface of the air deflector 200 and the outer side surface of the air deflector 200 are provided with the protruding drainage plates, so that the air outlet air flow flowing to the inner side surface and the outer side surface of the air deflector 200 can flow through the part of the air deflector 200 corresponding to the shielding section 122, the shielding section 122 and the inner component 800, the air outlet air flow flowing through the part of the air deflector corresponding to the shielding section 122, the shielding section 122 and the inner component 800 is ensured, the air outlet air flow flows through the inner side surface and the outer side surface of the part of the air deflector 200 corresponding to the shielding section 122, and the air outlet air flow flows through the whole shielding section 122, so that the effect of restricting the condensed water at the positions of the air deflector 200 and the shielding section 122 and the dust cleaning effect at the positions of the shielding section 122 are further improved.
In a modified embodiment, the accommodating portion 210 is a first accommodating groove provided on the inner side surface of the air guide plate 200 and a second accommodating groove provided on the outer side surface of the air guide plate 200. The first drainage plate 310 is disposed in the first receiving groove, and the second drainage plate 320 is disposed in the second receiving groove. In the embodiment in which the accommodating portion 210 is an accommodating hole communicating the inner side surface of the air deflector 200 and the outer side surface of the air deflector 200, the air conditioner indoor unit of this embodiment has the same beneficial technical effects, and this modified embodiment is not described here again.
Referring to fig. 7, in the present embodiment, a first limit protrusion 220 and a second limit protrusion 230 are provided on a sidewall of the receiving hole or the receiving groove; in addition, a third limiting protrusion 311 is arranged on the first drainage plate 310, and a fourth limiting protrusion 321 is arranged on the second drainage plate 320; in the first state, the third limiting protrusion 311 abuts against the first limiting protrusion 220, and the fourth limiting protrusion 321 abuts against the second limiting protrusion 230. And then, when the first drainage plate 310 and the second drainage member 300 are not separated from the accommodating hole after extending out of the side surface of the air deflector 200, the drainage member 300 is ensured to be switched between the first state and the second state normally.
Referring to fig. 6 or 7, in the present embodiment, the driving mechanism 400 includes an electromagnet disposed in the receiving hole and located between the first and second flow guiding plates 310 and 320, the electromagnet having first and second magnetic poles with opposite magnetism; and, the end of the first current-guiding plate 310 corresponding to the first magnetic pole is provided with a third magnetic pole, the end of the second current-guiding plate 320 corresponding to the second magnetic pole is provided with a fourth magnetic pole, and the magnetism of the third magnetic pole is opposite to that of the fourth magnetic pole.

Meanwhile, the embodiment in which the electromagnet is disposed in the accommodating hole can achieve the beneficial technical effects, and this modified embodiment can also achieve the beneficial technical effects, and will not be described herein.
In one implementation of the electromagnet in this embodiment, the electromagnet is an electromagnet; the electromagnet is configured such that the first magnetic pole is the same as the third magnetic pole and the second magnetic pole is the same as the fourth magnetic pole; the electromagnet is further configured such that the first pole is opposite in magnetic polarity to the third pole and the second pole is opposite in magnetic polarity to the fourth pole; alternatively, the electromagnet is also configured to be in a de-energized state.
It should be noted that when the electromagnet is an electromagnet, the drainage member 300 can be further switched between the first state and the second state by changing the magnetic pole of the switching electromagnet; in addition, the electromagnet can lose repulsive force to the drainage member 300 by de-energizing the electromagnet, at this time, since the drainage member 300 is provided with a magnetic pole, the electromagnet is attracted, and the drainage member 300 is switched from the second state to the first state, so that the drainage member 300 is accommodated in the accommodating hole.
In another implementation of the electromagnet in this embodiment, the electromagnet is a solenoid; the drop coil is configured such that the first magnetic pole is the same as the third magnetic pole and the second magnetic pole is the same as the fourth magnetic pole; the electromagnet is further configured such that the first pole is opposite in magnetic polarity to the third pole and the second pole is opposite in magnetic polarity to the fourth pole.
It is to be appreciated that when the electromagnet is a solenoid, the poles of the electromagnet may be switched by changing the flow direction of the energizing current of the solenoid, thereby switching the flow directing member 300 between the first state and the second state.
In this embodiment, the magnetic poles on the first drainage plate 310 and the second drainage plate 320 may be the magnetic poles of permanent magnets disposed on the first drainage plate 310 and the second drainage plate 320, or the magnetic poles of permanent magnets disposed on the first drainage plate 310 and the second drainage plate 320.
Referring to fig. 6 or 7, in the present embodiment, the total thickness of the first and second flow guiding plates 310 and 320 and the electromagnet is the same as the thickness of the wind deflector 200.
It can be appreciated that the total thickness of the first drainage plate 310, the second drainage plate 320 and the electromagnet is the same as the thickness of the air deflector 200, so that when the drainage member 300 is in the second state, the inner side or the outer side of the air deflector 200 is a smooth surface, and the inner side or the outer side of the air deflector 200 is not recessed at the position of the accommodating hole due to the fact that the total thickness of the drainage member 300 and the electromagnet is smaller than the thickness of the air deflector 200, so as to affect the air guiding effect of the air deflector 200; the inner side or the outer side of the air deflector 200 is not protruded at the position of the accommodating hole due to the fact that the total thickness of the drainage member 300 and the electromagnet is larger than the thickness of the air deflector 200, so that the air guiding effect of the air deflector 200 is affected. Therefore, the total thickness of the first drainage plate 310, the second drainage plate 320 and the electromagnet is the same as the thickness of the air deflector 200, so that the drainage member 300 can not interfere with the flow direction and the flow rate of the air outlet air flow of the air conditioner indoor unit when the air conditioner indoor unit does not need to limit the generation of condensed water on the air deflector 200 or when the air conditioner indoor unit operates in a heating mode or other modes, and the normal operation of the air conditioner indoor unit is ensured.
In a variant embodiment, the total thickness of the first electromagnet and the first drainage plate 310 is the same as the depth of the first receiving groove, and the total thickness of the second electromagnet and the second drainage plate 320 is the same as the depth of the second receiving groove. Similarly, by the arrangement, when the condensed water on the air deflector 200 is not required to be limited, or when the air conditioner operates in a heating mode or other modes, the drainage member 300 is further prevented from interfering with the flow direction and the flow rate of the air outlet air flow of the air conditioner indoor unit, so that the normal operation of the air conditioner indoor unit is ensured.
Referring to fig. 8, in the present embodiment, the air conditioner indoor unit further includes a humidity sensor 700. The humidity sensor 700 is connected to the driving mechanism 400, and the humidity sensor 700 is used for acquiring the ambient humidity of the indoor space acted by the indoor unit of the air conditioner; and, the driving mechanism 400 is configured to: under the condition that the ambient humidity is greater than or equal to a preset value, driving the drainage member 300 to be in a first state; in case the ambient humidity is less than the preset value, the drainage member 300 is driven in the first state.
It is appreciated that the humidity sensor 700 can be electrically connected to the drive mechanism 400 via the controller 900. The operation of the driving mechanism 400 may be controlled by the controller 900. And thus, the state of the drainage member 300 can be switched. And, only when the concentration in the indoor space reaches the preset value, the drainage member 300 is in the first state, effectively limiting the generation of condensed water on the air deflector 200 and at the shielding section 122. When the concentration in the indoor space is lower than the preset value, the condensation water is not easy to condense on the air deflector 200 and the shielding section 122, and the drainage member 300 is in the second state, so that when the generation of the condensation water on the air deflector 200 is not required to be limited, or when the air conditioner indoor unit operates in a heating mode or other modes, the drainage member 300 cannot interfere the flow direction and the flow rate of the air outlet air flow of the air conditioner indoor unit, and the normal operation of the air conditioner indoor unit is ensured.
