Referring to fig. 1 to 12, an embodiment of the present disclosure provides an indoor unit including a cabinet 10, a first air guide plate 20, and a second air guide plate 30. A casing 10 configured with an air outlet 101; the first air deflector 20 is arranged at the air outlet 101; the second air deflector 30 is arranged at the air outlet 101 and below the first air deflector 20, and the second air deflector 30 and the first air deflector 20 are arranged side by side along the width direction of the air outlet 101 so as to jointly open and close the air outlet 101; wherein the first air deflection 20 and the second air deflection 30 are operated synchronously, or the first air deflection 20 and the second air deflection 30 are operated independently and controlled.

Under the condition that the first air deflector 20 is opened, a first air outlet air duct is defined between the first air deflector 20 and the casing 10, the initial direction of air flow blown out from the first air outlet air duct is inclined upwards, cold air or hot air can be prevented from being directly blown to the head of a user, and the comfort of the user can be improved.

In actual use, the refrigerant gas is blown out from the air outlet 101. The refrigerating gas flows upwards obliquely along the first air outlet duct and is blown out. After the refrigerating gas is blown out, the refrigerating gas continues to flow obliquely upwards under inertia, so that the refrigerating gas reaches the indoor roof and is accumulated and diffused near the roof. Because the density of the cold air flow is larger than that of the indoor air, the cold air flow which is diffused near the roof slowly and downwards subsides under the action of gravity, and the effect of cooling the whole house is achieved. And because the cold air flow is not directly blown to the user, the user does not feel uncomfortable feeling of blowing.

In the case that the second air deflector 30 is opened, a second air outlet duct is defined between the second air deflector 30 and the casing 10, and an initial direction of the air flow blown out from the second air outlet duct is directly downward. Therefore, the refrigerating or heating air flow can quickly act indoors, and the aim of quick refrigerating or heating is fulfilled.

By adopting the indoor unit provided by the embodiment of the disclosure, the first air deflector 20 and the second air deflector 30 are arranged side by side along the width direction of the air outlet 101, and the first air deflector 20 and the second air deflector 30 synchronously act or are independently controlled to act, so that a user can select the first air deflector 20 and the second air deflector 30 to synchronously open or independently open according to requirements, and the refrigerating efficiency or the using comfort level can be improved.

Alternatively, in the case where both the first air deflector 20 and the second air deflector 30 are opened, the leeward side of the first air deflector 20 and the leeward side of the second air deflector 30 are disposed opposite to each other, so that the air-out flow of the air outlet 101 flows out in two air-out directions.

The first air deflection 20 and the second air deflection 30 each include an air deflection face and a leeward face. When the first air guide plate 20 and the second air guide plate 30 are both closed, the air guide surfaces of the first air guide plate 20 and the second air guide plate 30 face the inside of the casing 10, and the leeward surfaces are exposed to the external environment and correspond to the outer surfaces of the indoor units.

In the case where both the first air deflection 20 and the second air deflection 30 are opened, the first air deflection 20 is flipped open from top to bottom, and the second air deflection 30 is flipped open from bottom to top. In this way, the lee surface of the first air deflector 20 and the lee surface of the second air deflector 30 are arranged oppositely, the air outlet air flow of the air outlet 101 is divided into two parts, and flows out along the first air deflector 20 and the second air deflector 30 respectively, namely, the air flowing out along the first air deflector 20 is inclined upwards, so that the air flow is prevented from being directly blown to the head of a user, and the comfort of the user is improved; the air flowing out along the second air deflector 30 is directly downward, so that the air flow is rapidly acted on the room, and the purpose of rapid refrigeration or heating is realized. So, under the condition that first aviation baffle 20 and second aviation baffle 30 open simultaneously, through first aviation baffle 20 and second aviation baffle 30 with the air current reposition of redundant personnel of air outlet 101 for indoor set can compromise the travelling comfort of user and the effect of quick refrigeration or heating simultaneously, further promote user's use impression.

Optionally, the indoor unit further includes: the first driving device 40 is connected with the first air deflector 20 and is used for driving the first air deflector 20 to open and close; the second driving device 50 is connected with the second air deflector 30 and is used for driving the second air deflector 30 to open and close; the first driving device 40 and the second driving device 50 are respectively provided with one power source 60 correspondingly, or share one power source 60.

In the case that the first driving device 40 and the second driving device 50 are respectively provided with one power source 60 correspondingly, the first driving device 40 and the second driving device 50 can be independently controlled by the correspondingly provided power sources 60, that is, the purpose of independently controlling the first air deflector 20 and the second air deflector 30 is achieved, and therefore the first air deflector 20 and the second air deflector 30 can be independently opened.

When the first driving device 40 and the second driving device 50 share one power source 60, the first driving device 40 and the second driving device 50 are simultaneously driven by the same power source 60, so that the first air guide plate 20 and the second air guide plate 30 can operate synchronously.

Optionally, the power source 60 includes: a drive gear 601 in driving connection with the first drive 40 and/or the second drive 50; a motor 602 in driving connection with the driving gear 601; the driving gear 601 rotates forward and reversely under the driving of the motor 602 to drive the first driving device 40 and/or the second driving device 50 to act, so as to drive the first air deflector 20 and/or the second air deflector 30 to open and close; in the case where the first driving device 40 and the second driving device 50 share one power source 60, the power source 60 is located at an intermediate position between the first driving device 40 and the second driving device 50.

In the case that the first driving device 40 and the second driving device 50 share one power source 60, the motor 602 of the power source 60 rotates in a forward direction, and the driving gear 601 rotates to drive the first driving device 40 and the second driving device 50 to act, so as to drive the first air deflector 20 and the second air deflector 30 to open; the motor 602 of the power source 60 is reversed, and the driving gear 601 is rotated in a reverse direction, so that the first air deflection plate 20 and the second air deflection plate 30 are driven to close the air outlet 101 by the first driving device 40 and the second driving device 50.

In the case where the first driving device 40 and the second driving device 50 are respectively provided with a power source 60, for convenience of description and distinction, the power source 60 corresponding to the first driving device 40 is defined as a first power source 60, and the power source 60 corresponding to the second driving device 50 is defined as a second power source 60. Wherein, the first power source 60 and the second power source 60 each comprise a motor 602 and a driving gear 601.

The motor 602 of the first power source 60 rotates forward, and the driving gear 601 rotates to drive the first driving device 40 to act, so as to drive the first air deflector 20 to open. The motor 602 of the first power source 60 is reversed, and the driving gear 601 is rotated in the reverse direction, thereby driving the first air deflection plate 20 to be closed by the first driving device 40.

Similarly, the motor 602 of the second power source 60 rotates forward, and the driving gear 601 rotates to drive the second driving device 50 to act, so as to drive the second air deflector 30 to open. The motor 602 of the second power source 60 is reversed, and the driving gear 601 is rotated in the opposite direction, so that the second air deflector 30 is driven to be closed by the second driving device 50.

Optionally, the first air deflector 20 includes: the first rotating arm 203 is located on the air guiding surface of the first air guiding plate 20, and is used for being rotationally connected with the first driving device 40; the first sliding arm 204 is disposed on the same side as the first rotating arm 203 and is disposed near the second end edge of the first air deflector 20, so as to be slidably connected to the first driving device 40.

Under the condition that the first air deflector 20 is opened, the first driving device 40 pushes the first air deflector 20 outwards through the first rotating arm 203, and in the pushing process, the first driving device 40 and the first rotating arm 203 rotate relatively, so that the first air deflector 20 turns outwards, and the air outlet 101 is opened.

With the first air deflection 20 moved outwardly and flipped over, the first slider arm 204 is positioned adjacent the second end edge of the first air deflection 20 and is slidably coupled to the first drive means 40. In addition, the first sliding arm 204 is also rotatably connected with the first driving device 40. In this way, the connection of the first slider arm 204 to the first driving device 40 serves as a rotational connection point, i.e., defines the position of one end of the first air deflector 20 so that the other end is opened.

Optionally, the second air deflector 30 includes: the second rotating arm 303 is located on the air guiding surface of the second air guiding plate 30 and is used for being rotationally connected with the second driving device 50; the second sliding arm 304 is disposed on the same side as the second rotating arm 303 and near the second end edge of the second air deflector 30, and is used for sliding connection with the second driving device 50.

In the case that the second air deflector 30 is opened, the second driving device 50 pushes the second air deflector 30 outwards through the second rotating arm 303, and during the pushing process, the second driving device 50 rotates relative to the second rotating arm 303, so that the second air deflector 30 turns outwards, and the air outlet 101 is opened.

In the case where the second air deflection 30 is moved outward and turned over, the second slide arm 304 is located near the second end edge of the second air deflection 30 and is slidably connected to the second driving device 50. In addition, the second sliding arm 304 is also rotatably connected to the second driving device 50. In this way, the connection of the second sliding arm 304 to the second driving device 50 functions as a rotational connection point, i.e., defines the position of one end of the second air deflector 30 so that the other end is opened.

The first air guide plate 20 and the second air guide plate 30 are arranged side by side along the width direction of the air outlet 101, the first sliding arm 204 is arranged near the second end edge of the first air guide plate 20, and the second sliding arm 304 is arranged near the second end edge of the second air guide plate 30. Thus, the first sliding arm 204 and the second sliding arm 304 are disposed close to each other, the first rotating arm 203 is located above the first sliding arm 204, and the second rotating arm 303 is located below the second sliding arm 304, so that when the first air guiding plate 20 and the second air guiding plate 30 are opened, one air flow flows up along the first air guiding plate 20 and the other air flow flows down along the second air guiding plate 30, and the air flows out from the air outlet 101.

Optionally, the first driving device 40 includes: the first transmission member 401 includes a first gear tooth portion 402 and a second gear tooth portion 403 coaxially arranged, and the first gear tooth portion 402 is in meshed connection with the driving gear 601; the second transmission member 405 has a third gear tooth portion 406, and the third gear tooth portion 406 is engaged with the second gear tooth portion 403; wherein, the first transmission member 401 is connected with the first rotating arm 203 through a first connecting rod 408, and the second transmission member 405 is slidingly connected with the first sliding arm 204.

The first wind deflector 20 is in an initial state, in which the motor 602 is energized to drive the driving gear 601 to rotate, the driving gear 601 is engaged with the first gear teeth 402 to drive the first gear teeth 402 to rotate, the second gear teeth 403 coaxially provided with the first gear teeth 402 are rotated synchronously, and the third gear teeth 406 are driven to rotate while engaged with the third gear teeth 406. The first connecting rod 408 is forced to push the first rotating arm 203 to move outwards under the condition that the first transmission member 401 rotates, and under the condition that the second transmission member 405 and the first sliding arm 204 slide and are rotationally connected, the first air deflector 20 takes the joint of the second transmission member 405 and the first sliding arm 204 as a rotating point, and the first rotating arm 203 and the first connecting rod 408 rotate relatively, so that the first air deflector 20 is turned over, the opening of the first air deflector 20 is realized, and the flow area of the air port of the first air outlet duct is increased.

In the case that the first air deflector 20 is restored to the initial state from the opened state, the motor 602 is reversed, so that the driving gear 601 is driven to rotate reversely, the first transmission member 401 is also driven to rotate reversely, and the first connecting rod 408 is driven to move inwards, so that the first rotating arm 203 is driven to move inwards, and the connection part of the second transmission member 405 and the first sliding arm 204 is still used as a rotating point, so that the first air deflector 20 turns inwards to close the air outlet 101.

It should be noted that, in some embodiments, the connection between the second transmission member 405 and the first sliding arm 204 is not a fixed point, and the first sliding arm 204 can slide, so that interference between the first air deflector 20 and the chassis 10 or the internal components during the opening process of the first air deflector 20 is avoided, so that the first air deflector 20 can be opened and closed smoothly.

The first transmission member 401, the first link 408, the first air deflector 20 and the second transmission member 405 form a parallelogram mechanism, and the first air deflector 20 rotates around its connection with the second transmission member 405 during opening and closing.

Optionally, the second transmission member 405 is configured with a first chute 4071, the first sliding arm 204 is inserted into the first chute 4071 through the first sliding shaft 205, and when the second transmission member 405 rotates, the first sliding shaft 205 slides in the first chute 4071 to drive the first sliding arm 204 to rotate, so as to open and close the first air deflector 20.

The first sliding arm 204 is slidable in the first sliding groove 4071 of the second transmission member 405 via the first sliding shaft 205. When the second transmission member 405 rotates, the first sliding shaft 205 slides in the first sliding groove 4071, thereby driving the first sliding arm 204 to slide. In the sliding process of the first sliding arm 204, the displacement of the first rotating arm 203 is larger than the displacement of the first sliding arm 204, so that the first rotating arm 203 and the first air deflector 20 turn outwards or inwards relative to the joint of the first sliding arm 204 and the second transmission member 405, and the purpose of opening and closing the first air deflector 20 is achieved.

Optionally, the second driving device 50 includes: the third transmission member 501 comprises a fourth gear tooth part 502 and a fifth gear tooth part 503 which are coaxially arranged, and the fourth gear tooth part 502 is in meshed connection with the driving gear 601; a fourth transmission member 505 having a sixth gear tooth portion 506, the sixth gear tooth portion 506 being in meshed engagement with the fifth gear tooth portion 503; the third transmission member 501 is connected to the second rotating arm 303 through a second link 508, and the fourth transmission member 505 is slidably connected to the second sliding arm 304.

The second connecting rod 508 is forced to push the second rotating arm 303 to move outwards under the condition that the third transmission member 501 rotates, and under the condition that the fourth transmission member 505 slides with the second sliding arm 304 and is rotationally connected, the second air deflector 30 takes the joint of the third transmission member 501 and the second sliding arm 304 as a rotating point, and the second rotating arm 303 and the second connecting rod 508 rotate relatively, so that the second air deflector 30 is turned over, the opening of the second air deflector 30 is realized, and the flow area of the air port of the second air outlet duct is increased.

In the case that the second air deflector 30 is restored to the initial state from the opened state, the motor 602 is reversed, so that the driving gear 601 is driven to rotate reversely, the third transmission member 501 is also driven to rotate reversely, the second connecting rod 508 is driven to move inwards, the second rotating arm 303 is driven to move inwards, and the connection part of the fourth transmission member 505 and the second sliding arm 304 is still used as a rotating point, so that the second air deflector 30 turns inwards to close the air outlet 101.

It should be noted that, in some embodiments, the connection between the fourth transmission member 505 and the second sliding arm 304 is not a fixed point, and the second sliding arm 304 can slide, so that interference between the second air deflector 30 and the chassis 10 or the internal parts during the opening process of the second air deflector 30 is avoided, so that the second air deflector 30 can be opened and closed smoothly.

The third transmission member 501, the second link 508, the second air deflector 30 and the fourth transmission member 505 form a parallelogram mechanism, and the second air deflector 30 rotates around its connection with the fourth transmission member 505 during opening and closing.

Optionally, the first transmission member 401 includes: the first gear tooth part 402 is provided with meshing teeth on part or all of the outer edges for meshing connection with the driving gear 601; the second gear tooth portion 403 is coaxially disposed with the first gear tooth portion 402, and a part or all of the outer edges thereof are provided with engagement teeth for engaging with the second transmission member 405.

The first gear tooth portion 402 is circular, and in the case that only a part of the outer edge of the first gear tooth portion is provided with the engaging teeth, only when the engaging teeth of the first gear tooth portion 402 engage with the driving gear 601, the first transmission member 401 will rotate, so that the first air deflector 20 is prevented from being excessively opened or closed. Similarly, in the case where the second gear teeth 403 are formed in a circular shape and only a part of the outer edge thereof is provided with the engagement teeth, the second transmission member 405 can be driven to rotate only when the engagement teeth of the second gear teeth 403 engage with the second transmission member 405, thereby driving the first air deflector 20 to open and close.

Alternatively, the meshing teeth of the first gear tooth portion 402 and the meshing teeth of the second gear tooth portion 403 may be disposed correspondingly or in a staggered manner. Particularly in the case of a staggered arrangement of the two, so that the first transmission part 401 has a certain installation space for engagement with the drive gear 601 of the power source 60 and the second transmission part 405.

Optionally, the diameter of the second gear tooth portion 403 is smaller than the diameter of the first gear tooth portion 402.

In this way, the second gear tooth portion 403 overlaps the first gear tooth portion 402 when engaged with the second transmission member 405, so that the installation space between the first transmission member 401 and the second transmission member 405 can be saved, the whole structure is as compact as possible, the occupation space of the driving assembly is reduced, and the driving assembly is not only attractive, but also cost-saving.

Alternatively, the number of teeth of the meshing teeth of the second gear tooth portion 403 is larger than the number of teeth of the meshing teeth of the first gear tooth portion 402. In the case where the first gear tooth portion 402 is engaged with the drive gear 601, there are meshing teeth which do not mesh with the drive gear 601, that is, part of the meshing teeth of the first gear tooth portion 402 do not participate in the engaged drive connection, so that the mounting accuracy of the first transmission member 401 is lowered, that is, the end-to-end meshing teeth between the drive gear 601 and the first gear tooth portion 402 do not need to be correspondingly mounted. Likewise, a portion of the teeth of the second gear tooth portion 403 engage a meshing connection that does not participate in the second transmission member 405. In this way, the fitting accuracy of the first transmission member 401 and the second transmission member 405 can also be reduced.

The first transmission member 401 is rotatably connected with the first air deflector 20 through the first connection portion 404, and when the first transmission member 401 acts, the first transmission member 404 rotates relative to the first air deflector 20 through the first connection portion 404 to push the first air deflector 20 to turn over. Illustratively, the first connection 404 is rotatably coupled to a rotating arm of the first air deflector 20.

I.e. the first transmission member 401 and the second transmission member 405 are in a driving connection by means of a gear engagement.

During the drive connection of the second drive member 405 to the first drive member 401, the second drive member 405 is only rotated back and forth over a certain angular range. Thus, the meshing teeth are only arranged on part of the outer edge of the third wheel tooth part 406, which is beneficial to improving the processing efficiency and reducing the manufacturing cost; and excessive transmission can be avoided in the transmission process, so that the first air deflector 20 is overturned excessively.

Optionally, the diameter of the third wheel tooth 406 is larger than the diameter of the second wheel tooth 403; and/or the number of teeth of the meshing teeth of the third wheel tooth portion 406 is smaller than the number of teeth of the meshing teeth of the second wheel tooth portion 403.

The number of teeth of the meshing teeth of the third gear tooth part 406 is smaller than that of the meshing teeth of the second gear tooth part 403, so that the rotation angle of the second transmission member 405 is satisfied within the rotation range of the first transmission member 401, namely, the opening and closing of the first air deflector 20 movably connected with the second transmission member 405 are ensured.

Optionally, the second transmission member 405 further includes: the second connecting part 407 is formed by extending outwards from the edge of the third wheel tooth part 406, and is arranged to avoid the meshing teeth of the third wheel tooth part 406; the second connecting portion 407 is configured with a chute, and is slidably connected to the first air deflector 20.

In the case where the first air guide plate 20 and the second air guide plate 30 are opened and closed, the first driving device 40 and the second driving device 50 need to protrude out of the rail box 70 to be connected with the first air guide plate 20 and the second air guide plate 30. By providing the first guide structure 703 and the second guide structure 705 near the opening edge position of the rail box 70, interference with components in the rail box 70 when the wind deflector is connected to the driving device can be avoided.
