By adopting the technical scheme, cold air does not directly blow people when the indoor unit is used for refrigerating, and hot air quickly falls to the ground when the indoor unit is used for heating, so that the use experience of a user is effectively improved.

As shown in fig. 1, when the first air guiding plate 41 is located at the closed position, a part of the first air guiding plate 41 is located outside the outer surface of the panel 20. This arrangement enables the first air deflector 41 to wrap the panel 20 in the closed position, and also facilitates the first air deflector 41 to switch from the closed position to the open position.

As shown in fig. 1, the panel 20 has a first plate body 21 disposed in a vertical direction. The first end of the first plate 21 is spaced apart from the bottom case 10 to form an air outlet 30.

Further, the outer surface of the first plate body 21 is provided with a decorative boss structure. When the first air guiding plate 41 is located at the closed position, the end of the second end of the first air guiding plate 41 is matched with the step surface of the decorative boss structure, so that the outer surface of the first plate body 21 and the outer surface of the first air guiding plate 41 are arranged in an overlapping and flush manner. The arrangement of the decorative boss structure enables the first air deflector 41 and the first plate body 21 to have good connection stability and sealing performance, and meanwhile, the appearance of the indoor unit is more attractive.

As shown in fig. 2, a distance between the second end of the first air guiding plate 41 and the second end of the first plate 21 is X. Wherein X is more than or equal to 0 and less than or equal to 60 mm. The distance between the second end of the first air deflector 41 and the second end of the first plate 21 is a reserved height, so that the height for installing a display screen or other components is reserved when the first air deflector 41 and the first plate 21 are in complete sealing lap joint, and the practicability of the indoor unit is improved.

Wherein the width of the gap is Y, and Y is less than or equal to 15 mm. There is a gap between the first air guiding plate 41 and the bottom shell 10, and the gap can allow cold air to flow through the area where the end surface of the first air guiding plate 41 is not attached with the heat preservation cotton, so as to reduce the temperature difference between the two surfaces of the first air guiding plate 41 and reduce the condensation phenomenon.

In order to further reduce the condensation phenomenon of the first air guiding plate 41, the first air guiding plate 41 includes a plate body 411. The side of the plate body 411 facing the panel 20 is provided with a heat insulation structure.

As shown in fig. 3, when the first air guiding plate 41 is located at the first open position, an included angle formed between the air guiding direction of the first air guiding plate 41 and the horizontal plane is N, wherein N is greater than or equal to 20 ° and less than or equal to 80 °. An included angle formed between the wind guiding direction of the first wind guiding plate 41 and the horizontal plane is related to the overall width of the first wind guiding plate 41. The larger the overall width of the first air guide plate 41 is, the larger the N value is. The smaller the overall width of the first air guide plate 41 is, the smaller the N value is. The larger the N value is, the smaller the angle of pushing out the first air deflector 41 is, the cold air is blown to the ceiling close to the air outlet 30, the blowing-out distance is short, and the phenomenon that the cold air is sucked by the negative pressure of the air inlet to generate return air also exists. Considering that the blowing-out distance of the cold air adhered to the ceiling is kept between 3.5 and 4 meters on the basis that the cold air does not return air, the N value is set to be more than or equal to 20 degrees and less than or equal to 80 degrees, and the direct blowing prevention and the air return prevention at a longer distance can be realized.

The number of the first rack mechanisms 42 is at least one, and the first air deflector 41 is connected to the bottom case 10 through the first rack mechanisms 42. The first rack mechanism 42 can drive the first air deflector 41 to be located at different opening positions or closing positions, so that the air flow passing through the first air deflector 41 can be blown out along a preset direction. The first rack mechanism 42 may be replaced by another transmission form, such as a crank-link or the like. The movement locus of the first rack mechanism 42 determines the pushing-out stroke of the first air deflector 41.

Further, the air deflection assembly 40 also includes a linkage 43. The link mechanism 43 is at least one. The link mechanism 43 and the first rack mechanism 42 are provided at an interval in the width direction of the first air deflector 41.

The second rack mechanism and the first rack mechanism 42 both play a role of supporting the first air deflector 41, and meanwhile, the movement stroke of the first air deflector 41 can be limited by designing the movement range of the second rack mechanism.

As shown in fig. 4, the air deflection assembly 40 further includes a second air deflection plate 44. The second air deflection plate 44 is located inside the first air deflection plate 41. The second air guiding plate 44 is rotatably disposed relative to the first air guiding plate 41, so that the second air guiding plate 44 has a first air guiding position and a second air guiding position. When the first air guiding plate 41 is located at the first open position, the second air guiding plate 44 is located at the first air guiding position. When the first air guiding plate 41 is located at the second opening position, the second air guiding plate 44 is located at the second air guiding position. The second air guiding plate 44 plays a role of assisting the first air guiding plate 41 in blowing out the air flow. The second air guiding plate 44 has a first air guiding position and a second air guiding position, and the air outlet 30 is divided into different channels at different positions of the second air guiding plate 44, so that the flow direction of the air flow is changed. The provision of the second air deflection plate 44 can effectively control the blowing direction of the air flow.

Preferably, when the second air guiding plate 44 is located at the second air guiding position, the upper edge of the second air guiding plate 44 overlaps the panel 20. The lower edge of the second air guiding plate 44 is overlapped with the first air guiding plate 41. The air guide surface 441 of the second air guide plate 44 is disposed at a distance from the bottom case 10. As shown in fig. 4, when the second air guiding plate 44 is located at the second air guiding position, the second air guiding plate 44 divides the air duct so that the blown air flow is downward, and the indoor unit is in a heating state, so that the effect of hot air foot-up and carpet heating can be achieved. The guiding surface 441 may be a plane surface or an arc surface, preferably an arc surface.

The included angle between the plane where the air guide surface 441 is located and the horizontal plane is M, wherein M is more than or equal to 45 degrees and less than or equal to 90 degrees. The value of an included angle M between the plane where the air guide surface 441 is located and the horizontal plane determines the heating comfort of the air conditioner, when the value of M is larger than 90 degrees, hot air is only blown to the wall below the air conditioner, and the whole house cannot be heated uniformly and quickly. For better heating comfort, M is set to a value between 45 ° and 90 °.

The number of the first rack mechanisms 42 is two. The two first rack mechanisms 42 are provided at intervals along the longitudinal direction of the first air guide plate 41. The second air deflection plate 44 is located between the two first rack mechanisms 42. At least one of the two first rack mechanisms 42 is provided with a first motor for driving the second air deflector 44 to rotate. The arrangement is such that the second air deflector 44 moves smoothly and can accurately reach the open position.

The motor drives the second air guiding plate 44 to turn over to different positions to change the air outlet direction, and the second air guiding plate 44 and the first air guiding plate 41 can rotate relatively to control the air outlet direction.

Specifically, the second air guiding plate 44 is movably connected with the bottom case 10. This arrangement allows for more flexibility in the movement of the second air deflection member 44.

The indoor unit further includes a second motor. The second motor is at least one. The second motor is connected to at least one of the bottom case 10, the panel body 50, and the panel 20. The second motor is used for driving the first air deflector 41 to be located at the closed position, the first open position and the second open position. The arrangement reduces the production cost of the indoor unit and effectively reduces the whole weight of the indoor unit.

Further, when the first air deflector 41 is located at the first open position, the first end of the first air deflector 41 is disposed adjacent to the air outlet edge of the bottom case 10. The second end of the first air deflection plate 41 is disposed away from the panel 20. Along the air supply direction of the first air outlet channel, the distance between the first air guiding plate 41 and the panel 20 is gradually increased. The arrangement makes the airflow passing through the first air outlet channel stable in conveying, and no on-way loss is generated in the conveying process.

Preferably, when the first air deflector 41 is located at the second open position, the first end of the first air deflector 41 is away from the air outlet edge of the bottom shell 10. The second end of the first air deflection plate 41 overlaps the outer surface of the panel 20. The second air guiding plate 44 is overlapped with the end surface of the first end of the first air guiding plate 41, and the second air guiding plate 44 is located inside the first air guiding plate 41, so that a second air outlet channel is defined between the second air guiding plate 44 and the bottom case 10. The arrangement ensures that the airflow passing through the second air outlet channel cannot enter between the first air deflector 41 and the panel 20, and the air supply efficiency is improved.

According to another aspect of the present application, there is also provided a method for controlling an indoor unit, where the method is used to control the indoor unit in the above embodiments, and includes the following steps: the indoor unit has a heating mode. When the indoor unit is in the heating mode, the first air deflector 41 is pushed out by a preset distance towards the side away from the bottom shell 10 and then is located at the second opening position. The second air guiding plate 44 is controlled to be pushed out to the first air guiding plate 41 side by a preset distance and then located at the second air guiding position, so that the air outlet 30 supplies air downwards, when the indoor unit is closed, the second air guiding plate 44 is controlled to be retracted to the bottom shell 10 side to move to the initial position, and the first air guiding plate 41 is controlled to move to the closed position. In this arrangement, when the indoor unit is heating, the first air deflector 41 is pushed out to the second open position, and the second air deflector 44 guides the blown air flow downward, thereby realizing carpet heating. When the indoor unit is closed, the second air guiding plate 44 is rotated to the initial position to prevent mechanical interference during closing.

Further, the indoor unit has a cooling mode, and when the indoor unit is in the cooling mode, the first air deflector 41 is controlled to be located at the first open position after being pushed out by a preset distance toward the side away from the bottom shell 10, and the second air deflector 44 is controlled to be located at the first air deflecting position, so that the air outlet 30 realizes upward air supply. When the indoor unit is turned off, the second air guiding plate 44 is controlled to rotate to the initial position, and the first air guiding plate 41 is controlled to move to the closed position. When the indoor unit is cooling, the second air guiding plate 44 guides the air flow to blow out upward, and when the indoor unit is turned off, the second air guiding plate 44 rotates to an initial position, which may be a plurality of initial positions, and the initial position may be the position of the second air guiding plate 44 as shown in fig. 3, or other positions that rotate by a preset angle.

Specifically, when the indoor unit is in the cooling mode, the first air deflector 41 is controlled to be pushed out to a side away from the bottom casing 10 by a preset distance and then to be located at the second opening position, and the second air deflector 44 is controlled to be located at the second air guiding position, so that the air outlet 30 supplies air downwards. When second aviation baffle 44 was located the second wind-guiding position, can make cold wind blow off downwards, reached quick cryogenic effect, also can be the refrigeration mode under the indoor set air-out promptly, satisfied a small amount of consumers and need blow the demand of people for a short time, second aviation baffle 44 must use insulation material to keep warm this moment, otherwise has the problem that produces the condensation water.

According to the technical scheme, an upper air outlet and a lower air outlet are adopted, and the air outlet direction is changed by matching the second air guide plate 44 with the first air guide plate 41. When the indoor unit is used for refrigerating, the cold air flow is raised, and cold air does not blow people directly, so that shower type refrigeration can be realized, and the effects of uniform room temperature distribution and comfort increase are achieved; when the indoor unit heats, hot air flow is pressed downwards, hot air rises from the ground, carpet heating can be realized, and the effects of uniform room temperature distribution and good comfort are achieved.

Preferably, the second air deflection plate 44 may be directly mounted on the first air deflection plate 41. When the indoor unit is refrigerating, the second air deflector 44 and the first air deflector 41 divide the air outlet 30 into long obliquely upward air ducts, so that the air supply distance is prolonged, the air flow is prevented from blowing directly to a user, and the user experience is effectively improved. When the indoor unit heats, one end of the second air deflector 44 is lapped with the air duct on the panel 20, and the other end is lapped with the first air deflector 41, so that the air outlet 30 is divided into obliquely downward air ducts, downward air outlet is realized, and carpet heating experience is brought to users by combining with the air sweeping blades.

The cold air blows out along the surfaces of the second air deflector 44 and the first air deflector 41, so that the cold air is blown out from the upper part. Because the upper and lower surfaces of the second air deflector 44 are both provided with cold air, no sponge which has the functions of heat preservation and condensation prevention needs to be adhered on the second air deflector 44. When the refrigeration is shut down, the second air deflector 44 rotates counterclockwise to the initial position, and then the first air deflector 41 is driven by the rack motor to retract to the closed state of the initial position.

As shown in fig. 9, the working flow of the indoor unit in the heating mode is as follows: after the heating mode is started, at least one motor on the left side and the right side of the second rack mechanism drives the upper end rack and the link mechanism 43 to move along a preset track, the link mechanism 43 pushes the first air deflector 41 to move, at the same time, at least one motor on the left side and the right side of the first rack mechanism 42 drives the first rack mechanism 42 to be pushed out to a second opening position along the preset track, the second air deflector 44 rotates anticlockwise to a cooling angle to a second air deflecting position under the driving of the motor, at the moment, one section of the second air deflector 44 is completely overlapped with an upper air inlet of the panel 20, the other end of the second air deflector is overlapped with the first air deflector 41, hot air is not blown to the first air deflector 41, and is blown out downwards only through the second air deflector 44, so that the hot air is blown out downwards. The left and right wind sweeping of the wind sweeping blades can be realized by swinging the wind sweeping blades left and right. When the indoor unit is turned off during heating, the second air deflector 44 rotates clockwise to a preset angle and is closed to an initial position, and the first air deflector 41 is driven by the rack motor to retract to a closed state of the initial position.

Further, the second air deflection plate 44 is not assembled to the first air deflection plate 41, for example, the second air deflection plate 44 may be disposed on the bottom case 10. The upper end part of the first air deflector 41 and the first plate body 21 are provided with decorative boss structures, so that gaps can not be seen by human eyes after the indoor unit is hung up, and the decorative boss structures can also play a role in supporting. The first air guiding plate 41 prevents the first air guiding plate 41 from generating a gap with the first plate 21 due to the influence of gravity, and the upper end of the first air guiding plate 41 may be flush with the first plate 21.

The indoor unit in the above embodiment may also be used in the technical field of air conditioning equipment, that is, according to another aspect of the present invention, an air conditioner is provided, which includes an indoor unit, where the indoor unit is the indoor unit in the above embodiment.
