At present, the panel of the embedded air conditioner indoor unit with four-direction air outlets is usually provided with 4-8 air outlets, and the air outlets encircle the air inlet at the center of the panel. When the air outlet is 4, 4 air outlets are 4 main air outlets respectively arranged along 4 directions, and when the air outlet is 8, the air outlet comprises 4 main air outlets and 4 auxiliary air outlets, the 4 main air outlets are respectively arranged along 4 directions, one auxiliary air outlet is arranged between every two adjacent main air outlets, and the positions of the auxiliary air outlets are approximately located at four corners of the panel. An air deflector is usually arranged in the main air outlet to adjust the air supply angle of the main air outlet.
Because the air outlet and the air inlet are both positioned on the same plane of the panel, and the distance between the air outlet and the air inlet is short, the phenomenon of air return short circuit is easy to occur, namely the air flow of the air outlet is blown out and then directly sucked back by the air inlet, and the air is not sent to a room. In order to avoid the phenomenon of air return short circuit as far as possible, the opening angle range of the air deflector is generally about 30-60 degrees, namely the maximum opening angle is smaller, and the air supply angle range is smaller. In order to make the hot air land during heating, the opening angle of the air deflector is usually required to be controlled to be larger, so that the air outlet is blown out to the lower side of the room along the air deflector, and the maximum opening angle of the air deflector in the prior art is smaller, so that the heated air is difficult to land and cannot form an effective floor heating effect, and a user feels that the heating effect of the air conditioner is poor.
In addition, in the prior art, in order to prevent the condensation phenomenon from generating, a gap of 5-6 mm is usually reserved between the periphery of the air deflector and the panel, and cold air overflows vertically and directly blows downwards to users during refrigeration, so that the users feel that the refrigeration effect of the air conditioner is poor.

The air conditioner in this application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and refrigerating or heating an indoor space.
The low-temperature low-pressure refrigerant enters the compressor, the compressor compresses the refrigerant gas into a high-temperature high-pressure state, and the compressed refrigerant gas is discharged. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state formed by condensation in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner may adjust the temperature of the indoor space throughout the cycle.
An outdoor unit of an air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, an indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater of a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler of a cooling mode.

The air duct is formed in the machine body 100, and a heat exchanger, other indoor unit structural components and electrical components are disposed in the air duct, which are the same as those in the prior art and are not described herein.
The panel 200 is provided at one end of the body 100, and the ceiling machine is generally vertically installed upward on the indoor ceiling, so that the panel 200 is positioned at the bottom end of the body 100, and the body 100 of the ceiling machine is generally rectangular, and accordingly, the panel 200 has a rectangular shape, and the area of the panel 200 is larger than the cross-sectional area of the body 100, so that the panel 200 is attached to the lower surface of the ceiling when the body 100 is embedded in the ceiling. The panel 200 is provided with an air inlet 210 and a plurality of main air outlets 220, the air inlet 210 is positioned in the central area of the panel 200, the plurality of main air outlets 220 are distributed around the main air outlets 220 and are communicated with the air inlet 210 through an air channel in the machine body 100, indoor air flows enter the air channel of the machine body 100 through the air inlet 210, and after heat exchange of a heat exchanger, the indoor air flows are blown into a room through the main air outlets 220, so that the indoor temperature is regulated. In this embodiment, the number of the main air outlets 220 is 4, which are respectively disposed at four sides of the panel 200, each main air outlet 220 is rectangular and long, and extends from one end of the side of the panel 200 to the other end, two adjacent main air outlets 220 are each provided with an auxiliary air outlet, the 4 auxiliary air outlets are respectively disposed at four corners of the panel 200, the structure of the auxiliary air outlets is the same as that of the prior art, and the auxiliary air outlets are not described in detail herein, and are omitted from illustration.
The main air guide plates 300 are arranged in one-to-one correspondence with the main air outlets 220, and are rotatably arranged at each main air outlet 220, that is, the main air outlets 220 can be rotatably opened and closed by rotating the main air guide plates, the rotating shafts of the main air guide plates 300 are parallel to the side edges of the panel 200 where the main air guide plates 300 are positioned, and the rotary opening and closing of the main air guide plates 300 are usually driven by a motor. The outline shape of the main air deflector 300 is adapted to the main air outlet 220, so that the main air outlet 220 can be closed as much as possible when the main air deflector is turned off, and a complete integral panel is formed with the panel 200. The main air guide plate 300 includes a main air guide plate first end 310 and a main air guide plate second end 320, which are respectively disposed corresponding to two ends of the main air outlet 220 in the length direction, i.e., the main air guide plate first end 310 is located at one end of the main air outlet 220, and the main air guide plate second end 320 is located at the other end of the main air outlet 220.
In this embodiment, the secondary air deflectors 400 are disposed on the first end 310 of the primary air deflector and the second end 320 of the primary air deflector, the secondary air deflectors 400 at both ends are symmetrical, and the length of each secondary air deflector 400 is 35% -45% of the length of the primary air outlet 220. The auxiliary air deflectors 400 are positioned on the inner sides of the main air deflectors 300, namely, two auxiliary air deflectors 400 are correspondingly arranged on each main air deflector 300, namely, two auxiliary air deflectors 400 and one main air deflector 300 are arranged at each main air outlet 220. An air supply channel 500 is formed between the secondary air deflector 400 and the primary air deflector 300, the air supply channel 500 being elongated with a length direction parallel to the length direction of the primary air outlet 220, and having an air supply channel first end 510 proximate to the primary air deflector first end 310 and an air supply channel second end 520 distal to the primary air deflector first end 310.
In this embodiment, by arranging the auxiliary air guide plate 400 on the inner side of the main air guide plate 300, the auxiliary air guide plate 400 is at least located at the first end 310 of the main air guide plate, and forms the air supply channel 500 with the main air guide plate 300, because the air supply channel 500 is narrower than the original main air outlet 220, the air outlet at the end of the main air outlet 220 is flattened when flowing through the air supply channel 500, and is further beneficial to being dispersed to the outer side of the end of the main air outlet 220 along the length direction of the main air outlet 220 when being blown out, and the air flow direction after flowing out through the air supply channel 500 is shown by hollow arrows in fig. 4 and 5, so that the air supply breadth of the indoor unit of the air conditioner can be improved, that is, the air supply range in the horizontal direction is enlarged, the indoor unit Zhou Xiangquan direction air supply can be realized, and further the indoor temperature distribution uniformity is improved, and the air outlet speed is further improved after being compressed by the air outlet flowing through the air supply channel 500 is further improved, and the air supply distance is further increased.
In order to further improve the air supply width and realize wide coverage air supply, referring to fig. 4, 5, 9 and 10, a plurality of air guide ribs 410 located in the air supply channel 500 are arranged on the auxiliary air guide plate 400, and the plurality of air guide ribs 410 are arranged at intervals between the first end 510 of the air supply channel and the second end 520 of the air supply channel, that is, along the length direction of the air supply channel 500, each air guide rib 410 includes an inclined guide portion 411 inclined at an acute angle α with respect to the air outlet flow direction of the main air outlet 220 (as indicated by the hollow arrow on the side of the straight guide portion 412 in fig. 9 and as indicated by the hollow arrow in fig. 10), and the inclined guide portion 411 can guide part of the air outlet flow (the air flow flowing through the air supply channel 500) of the main air outlet 220 to the outside of the end portion of the main air outlet 220 along the length direction of the main air outlet 220.
In this embodiment, the length direction of the auxiliary air deflector 400 is parallel to the length direction of the main air outlet 220, and the inclination angle (i.e. α value) of the inclined guiding portion 411 of each air deflector 410 is gradually reduced along the direction from the first end 510 of the air supply channel to the second end 520 of the air supply channel, i.e. the inclination amplitude of the inclined guiding portion 411 of each air deflector 410 is gradually gentle, because the air outlet wind speed is higher at the position where the second end 520 of the air supply channel is close to the center of the main air outlet 220, if the inclination angle of the inclined guiding portion 411 is too large, the more obvious the blocking of the air outlet flow is, the more easy the noise is generated, and in order to achieve both the air supply breadth and the reduction of the air outlet noise, in this embodiment, the inclination angle of the inclined guiding portion 411 of each air deflector 410 is gradually reduced along the direction from the first end 510 of the air supply channel to the second end 520 of the air supply channel, wherein the inclination angle range of the inclined guiding portion 411 with the maximum inclination angle is 45 ° being less than or equal to α 65 °.
As also shown in fig. 10, among the plurality of guide ribs 410, the guide ribs 410 near the end of the main air outlet 220 further include a straight guide portion 412, the straight guide portion 412 is parallel to the air outlet flow direction of the main air outlet 220 and is located upstream of the inclined guide portion 411, so as to guide the air outlet flow entering the air supply channel 500 along the initial flow direction, and gradually guide and transition to the inclined guide portion 411, so as to reduce the air outlet noise as much as possible, and an arc transition is adopted between the straight guide portion 412 and the inclined guide portion 411, so that the air flow is smooth. Since the guide rib 410 at the second end 520 of the air supply channel is located in the high-speed region of the air flow, the guide rib 410 only needs to have the inclined guide portion 411 with a smaller inclination angle, and the guide length is smaller, so as to reduce the air-out noise.
In the same way, in order to further reduce the air-out noise, the length of the air-guiding rib 410 is gradually reduced along the direction from the first end 510 of the air-supplying channel to the second end 520 of the air-supplying channel, that is, the length of the air-guiding rib 410 is gradually increased along the direction from the second end 520 of the air-supplying channel to the first end 510 of the air-supplying channel, so as to prolong the guiding path of the air-guiding rib 410 at the outer end, and make the air-out airflow at the outer end flow to the outside of the end of the main air-outlet 220 as much as possible, so as to further increase the air-out range along the length direction of the air-outlet.
Specifically, as shown in fig. 10, in this embodiment, taking the secondary air deflector 400 on the first end 310 of the primary air deflector as an example, the length dimension W5 of the secondary air deflector 400 is 0.35-0.45 of the total length of the primary air outlet 220, the width D1 of the outer end (i.e. the end far from the center of the primary air outlet 220) is 0.4-0.75 of the width of the primary air outlet 220, the width D2 of the inner end (i.e. the end near the center of the primary air outlet 220) is 0.35-0.75 of the width of the primary air outlet 220, and the two ends can be connected by an arc or a high-order curve to form the secondary air deflector 400 with an arc side edge, and the width at the maximum width of the secondary air deflector 400 is not more than 1.1 times the width D1 of the outermost end. The inclined guide portion 411 of the guide rib 410 is inclined toward the outer end of the sub-air guide plate 400 to guide the air flow flowing through the air supply duct 500 toward the outside of the end of the main air outlet 220 along the length direction of the main air outlet 220, so as to increase the air outlet range along the length direction of the air outlet. The width D3 of the guide ribs 410 from the inner edge of the auxiliary air deflector 400 is 5-12 mm, the number 2 of the guide ribs 410 with the inclined guide parts 411 and the flat guide parts 412 is less than or equal to n and less than or equal to 6, the distance W1= (0.1-0.3) x W5 between the adjacent guide ribs 410 with the inclined guide parts 411 and the guide ribs 410 with the flat guide parts 412 adjacent thereto is less than or equal to (0.8-1.2) x W1, the distance W3= (0.6-1) x W1 between the adjacent guide ribs with the inclined guide parts 411, the distance W4=0.5 x W3 between the guide ribs 410 with the inclined guide parts 411 at the second end 520 of the air supply channel is less than or equal to 0.5 x W3, the width of each flat guide part 412 is more than D4 > D5 > D6 > D7, the width H of each inclined guide part 411 is gradually reduced from the outer end of the auxiliary air deflector 400 to the inner end of the guide ribs 410, and the width H of the outer end of the inclined guide part is the inclined guide part 411 is equal to 24mm or more than or equal to 6 mm.
In some embodiments of the present application, the auxiliary air guiding plate 400 may rotate relative to the main air guiding plate 300, and the direction of the rotation axis thereof is parallel to the direction of the air outlet flow of the main air outlet 220, i.e. perpendicular to the direction of the rotation axis of the main air guiding plate 300; when the main air guide plate 300 is rotated and opened, the sub air guide plate 400 is rotated synchronously in a direction to increase the width c of the air duct 500, and the width c of the air duct 500 gradually decreases in a direction from the end of the main air outlet 220 toward the second end 520 of the air duct, i.e., in a direction from the end of the air duct to the center.
Specifically, as shown in fig. 4 to 6, the auxiliary air guide plate 400 is hinged with the main air guide plate 300 at its inner end, specifically, may be hinged by a hinge 900 or a hinge, and the outer end of the auxiliary air guide plate 400 is connected with a motor to drive the auxiliary air guide plate 400 to rotate, and is configured to synchronously rotate as the opening angle of the main air guide plate 300 increases, in a direction in which the width c of the air supply duct 500 increases, i.e., the outer end of the auxiliary air guide plate 400 is lifted upward with respect to the main air guide plate 300 to increase the gap between the auxiliary air guide plate 400 and the main air guide plate 300, while the width of the air supply duct at the first end 510 of the air supply duct is greater than the width of the air supply duct at the second end 520 of the air supply duct. In this embodiment, the auxiliary air deflector 400 rotates clockwise around its hinge axis by an angle of 3 ° to 5 °. When the main air guide plate 300 and the auxiliary air guide plate 400 are both in the closed and reset state, the air supply channel 500 can be an equal-width channel with the width of 10 mm-15 mm or a non-equal-spacing channel, the first end of the air supply channel is a large-width end, the second end (namely the hinged end) is a small-width end, and the width of the large-width end is about 1.1-1.2 times that of the small-width end.
The auxiliary air deflector 400 rotates in this way, because the auxiliary air deflector 400 occupies a part of the air outlet area, the air outlet resistance is increased, the air outlet quantity is relatively reduced, the defect is overcome, the fan speed of the indoor unit is generally increased correspondingly, and the noise is increased correspondingly due to the increase of the fan speed, so that the air resistance is reduced as much as possible, the noise is not increased, the auxiliary air deflector 400 is hinged with the main air deflector 300 at the inner end of the auxiliary air deflector 400, the opening angle is increased along with the rotation of the main air deflector 300, the air resistance is reduced, the fan speed is not increased, the width of the air supply channel 500 is gradually reduced along the direction of the first end 510 of the air supply channel towards the second end of the air supply channel, namely, the width of the air supply channel is increased as close to the first end 510 of the air supply channel as possible, the air outlet air flow is spread towards the outer side of the end along the length direction of the air outlet, and the air supply breadth is increased.
Fig. 11 is a simulation diagram of the air-out airflow of a main air outlet in the same direction of a ceiling fan and an air-conditioning indoor unit in the same room, and the air-out airflow distribution width a2 of the main air outlet 220 of the air-conditioning indoor unit in the application is obviously greater than the air-out airflow distribution width a1 of the main air outlet of the ceiling fan in the prior art under the condition that only the air-guiding structure of the main air outlet is different, and meanwhile, the air-out distance b2 in the up-down direction is obviously greater than the air-out airflow distribution distance b1 of the main air outlet of the ceiling fan in the prior art.
In order to avoid cold air blowing during cooling, the opening angle of the main air guide plate 300 is usually controlled to be smaller to deflect the air guide at the upper side of the room according to the principles of hot air rising and cold air sinking. In order to land the hot air during heating, it is generally necessary to control the opening angle of the main air guide 300 to a larger extent so that the outlet air is blown out toward the lower side of the room along the air guide. For the ceiling machine, since the main air outlet 220 and the air inlet 210 are both on the panel 200 and are relatively close to each other, the opening angle of the main air guide plate 300 is relatively large during heating to easily cause short circuit of the inlet air and the outlet air return air, so that the outlet air is easily sucked back by the air inlet 210, and the hot air is difficult to land, and the effect of good heating cannot be achieved.
In order to solve the problem of easy occurrence of short circuit of return air in the conventional ceiling heating, in some embodiments of the present application, as shown in fig. 4 and fig. 6 and 7, the indoor unit of an air conditioner further includes a wind shielding member 600, where the wind shielding member 600 is also installed on the panel 200 and rotatably disposed between the main air outlet and the air inlet 210, and when the main air guiding plate 300 is rotated to be opened, the wind shielding member 600 is rotated to a state of forming a certain angle beta with the panel 200 toward the bottom of the panel 200.
By arranging the wind shielding component 600, a certain blocking effect can be achieved between the air inlet 210 and the main air outlet 220 to the air outlet of the main air outlet 220, and the phenomenon of air return short circuit caused by the air outlet being sucked back by the air inlet 210 is reduced, so that the maximum opening angle of the main air guide plate 300 can be correspondingly increased during heating, for example, the maximum opening angle is increased to about 75 degrees from about 60 degrees in the prior art, and the purpose that hot air can quickly reach the ground of a room during heating is achieved, so that the use comfort is improved.
Specifically, the wind shielding member 600 is in a strip shape, the length direction of the wind shielding member 600 is parallel or nearly parallel to the length direction of the main wind deflector 300, the width of the wind shielding member 600 is 10-20 mm, the wind shielding member 600 can be driven to rotate by a motor arranged at one end, and two ends of the wind shielding member 600 extend to the outer sides of two ends of the main wind outlet 220 respectively, so that wind-up of the wind outlet is prevented from being sucked into the wind inlet 210 as large as possible.
In addition, in the prior art, in order to prevent the condensation phenomenon, a gap of 5-6 mm is usually left between the periphery of the main air guide plate 300 and the panel 200, so that cold air overflows and directly blows vertically downwards to users during refrigeration, and the user experience is poor. To further solve this problem, in some embodiments of the present application, the rotation axis of the wind shielding component 600 is parallel to the rotation axis of the main wind shielding plate 300, the angle β between the wind shielding component 600 and the panel 200 is not greater than 90 °, and when the angle β between the wind shielding component and the panel 200 is acute, the wind shielding component 600 is inclined to the side of the main wind shielding plate 300 and is located below the gap between the main wind shielding plate 300 and the panel 200, and is located on the air outlet path of the air flow blown out from the gap, when the air overflows from the gap and blows down vertically, the inclined wind shielding component 600 can guide the air shielding component to a direction away from the air inlet 210, so as to be beneficial to prevent the air from being sucked and sucked into the air inlet 210 to generate the air return short circuit phenomenon; when the angle β between the wind shielding member 600 and the panel 200 is 0 °, the wind shielding member 600 is retracted to be fitted to the panel 200.
In some embodiments of the present application, the auxiliary air guide plate 400, the main air guide plate 300 and the wind shielding member 600 are driven by the same motor 700 through the link mechanism 800 to rotate synchronously, and as the opening angle of the main air guide plate 300 increases, the auxiliary air guide plate 400 rotates synchronously in a direction that increases the width c of the air supply channel 500, and the opening angle of the wind shielding member 600 increases.
Specifically, as shown in fig. 4, 6 and 7, the secondary air guide plate 400, the primary air guide plate 300 and the wind shielding member 600 are connected to each other at the first end 310 of the primary air guide plate 300, the rotation power of the secondary air guide plate 400, the primary air guide plate 300 and the wind shielding member 600 are all from the same motor 700, the motor 700 is mounted on the panel 200 and is positioned at one end of the primary air outlet 220, the motor shaft is connected with the first end 310 of the primary air guide plate, the second end 320 of the primary air guide plate is hinged with the panel 200, and the motor 700 directly drives the primary air guide plate 300 to rotate; the link mechanism 800 includes a rocker 810, a first link 820 and a second link 830, where the rocker 810 is curved, the first link 820 and the second link 830 are both linear, and all the three have two ends, the middle of the rocker 810 is sleeved on the motor shaft and fixedly connected with the motor shaft, the first link first end 821 is hinged with the first end 811 of the rocker, the second link second end 822 is hinged with the outer end of the auxiliary air deflector 400, the inner end of the auxiliary air deflector 400 is hinged with the main air deflector 300, the first link first end 831 is hinged with the second link second end 812 of the rocker, the second link second end 832 is hinged with the end of the outer side of the wind shielding component 600 (i.e. the side close to the side where the main air deflector 300 is located), and the inner side of the wind shielding component 600 (i.e. the side close to the side where the air inlet 210 is located) is hinged with the panel 200. The linkage 800 at the main damper second end 320 is similar to the specific structure of the linkage 800 at the main damper first end 310 shown in fig. 4, 6 and 7, except that the motor is not provided at this end, but rather the passive rotation is implemented under the action of the motor 700 at the main damper first end 310, and the middle part of the rocker 810 is sleeved on a hinge shaft fixed to the main damper second end 320, which hinge shaft enables the main damper second end 320 to hinge with the panel 200.
As shown in fig. 4, 6 and 7, the principle of synchronous linkage rotation of the secondary air deflector 400, the main air deflector 300 and the wind shielding member 600 is as follows: the motor 700 rotates counterclockwise to drive the main air guide plate 300 to rotate downward to open, and the rocker 810 rotates counterclockwise (the second end moves downward and the first end moves upward) synchronously, so that the wind shielding part 600 is pushed to rotate downward to open by the second connecting rod 830, and the outer end of the auxiliary air guide plate 400 is pushed to move upward by the first connecting rod 820, namely, the auxiliary air guide plate 400 rotates clockwise around the hinge shaft thereof, so that the distance between the auxiliary air guide plate 400 and the main air guide plate 300 is increased.
By adopting the link mechanism 800, the synchronous rotation of the main air deflector 300, the auxiliary air deflector 400 and the wind shielding component 600 can be realized through one motor 700, and the indoor unit has the advantages of simple structure, low cost, good synchronism, high reliability and small occupied space, and is particularly suitable for indoor units with limited installation space such as ceiling units.
