Background
With the development of the times and the progress of technology, users not only expect faster cooling and heating speeds of air conditioners, but also pay more attention to the comfort performance of the air conditioners.
However, in order to achieve more rapid cooling and heating, it is inevitable to supply a large amount of air. However, when cold air or hot air with an excessive wind speed is directly blown to a human body, discomfort of the human body is inevitably caused. The long-term cold wind blowing of human body can also cause air conditioning diseases.
Therefore, how to realize comfortable air supply of the air conditioner becomes a technical problem to be solved urgently in the air conditioner industry.
Disclosure of Invention
The object of the present invention is to provide an air conditioning indoor unit that overcomes or at least partially solves the above mentioned problems.
The invention aims to provide an air conditioner indoor unit capable of meeting the requirements of cold air rising blowing and hot air sinking blowing.
The invention further aims to improve the lifting and air guiding effects of the second air guide plate.
In particular, the present invention provides an air conditioning indoor unit comprising:
the shell is provided with an air outlet facing forwards and downwards;
the first air deflector and the second air deflector are respectively and rotatably arranged on the front side and the lower side of the air outlet so as to cooperatively open and close the air outlet, and the second air deflector is configured as follows:
the air guide device can rotate to a front air guide state which is positioned at the lower side of the air outlet and enables the air guide surface to face upwards so as to guide the air flow of the air supply to the front, the front upper part or the front lower part; and
the air guide device can rotate to a downward air guide state which is positioned at the rear side of the air outlet and enables the air guide surface to face forward, so that the air supply flow is guided downwards.
Optionally, the rotation axis of the first air deflector is located at an end of the first air deflector facing downward when in the closed state.
Optionally, the rotating shaft of the first air deflector is located between the upper end and the lower end of the first air deflector in the closed state, and is spaced from the upper edge of the air outlet.
Optionally, the end of the second wind deflector facing backwards when in the front wind guiding state is rotatably mounted to the housing, and the rotating shaft of the second wind deflector is located at the lower edge of the wind outlet.
Optionally, the rotation axis of the first wind deflector and the rotation axis of the second wind deflector are parallel to each other.
Optionally, the second air deflection plate comprises: the air deflector body is arranged on the shell, and when the second air deflector is in a front air guiding state, the upward surface of the air deflector body forms an air guiding surface; and the air raising part is formed on the air guide surface and used for guiding the air supply airflow to obliquely flow out upwards and forwards when the second air deflector is in a front air guide state.
Optionally, the wind raising part comprises a wind raising plate arranged at an interval with the wind guide surface; if the end parts of the air deflector body facing forwards and backwards when the air deflector body is in a front air guiding state are respectively a first end and a second end, and the distance between the air raising plate and the air guiding surface is gradually increased in the direction from the second end to the first end.
Optionally, the wind deflector is arranged at the first end of the wind deflector body; and the projection of the tail end of the wind raising plate far away from the second end on the wind guide plate body falls outside the wind guide surface.
Optionally, the other side of the air deflector body facing away from the air deflecting surface is formed with a streamline convex part at a section adjacent to the first end.
Optionally, the indoor unit of an air conditioner further includes: the air duct is connected with the air outlet inside the shell and used for guiding the air supply flow to the air outlet; and the upper wall of wind channel includes the preceding flat plate section that extends backward from the upper edge of air outlet, the arc plate section that extends backward from preceding flat plate section rear end, follow the back flat plate section that the arc plate section rear end extended backward the top, follow the arc changeover portion that the flat plate section rear end was earlier backward then upwards extended and follow the last flat plate section that the upper edge of arc changeover portion extended forward the top.
The air-conditioning indoor unit has multiple air supply modes, and improves the air supply comfort experience of the air-conditioning indoor unit. For example, during cooling operation of the air conditioner, the first air deflector can be selectively adjusted to be in an open state and the second air deflector can be adjusted to be in a front air guiding state at the lower side of the air outlet, so that the second air deflector guides the air flow (cold air) to the front, the front upper side or the front lower side. For example, the second air deflector can be selected to guide the cold air to the front upper side so as to blow the cold air out at a larger upward-rising angle (an included angle between an air flow blowing angle and a horizontal plane) to avoid a human body, and the cold air is scattered downwards after reaching the highest point, so that a 'shower type' refrigeration experience is realized. When the air conditioner is used for heating, the second air deflector can be selectively adjusted to be in a downward air guiding state that the air guiding surface faces forward and is positioned at the rear side of the air outlet, so that a channel for guiding air supply flow (hot air) to flow downwards is formed between the first air deflector and the second air deflector, the hot air is directly blown to the bottom surface in a vertical downward mode, and foot warming experience is achieved.
Further, in the air conditioning indoor unit according to the present invention, the rotation shaft of the first air guide plate is located at an end portion of the first air guide plate facing downward when the first air guide plate is in the closed state. Therefore, when the second air deflector is in the front air guiding state, the first air deflector can be rotated to be parallel to the second air deflector or the included angle is smaller than 180 degrees, so that the airflow flowing out of the second air deflector is further lifted and guided by the first air deflector, and the lifting and guiding effect is enhanced. In addition, the first air deflector can also be rotated to a state that the included angle between the first air deflector and the second air deflector is larger than 180 degrees, so that a front passage of the air outlet is thoroughly opened, the first air deflector does not participate in air guiding, and the second air deflector is used for lifting and guiding air, so that the air flow resistance is smaller.
Furthermore, in the indoor unit of an air conditioner according to the present invention, the rotating shaft of the first air guiding plate may be located between the upper and lower ends of the first air guiding plate in the closed state, and may be spaced from the upper edge of the air outlet. Therefore, when the second air deflector is in the front air guiding state, the first air deflector can be rotated to be parallel to the second air deflector or the included angle is smaller than 180 degrees, so that the airflow flowing out of the second air deflector is further lifted and guided by the first air deflector, and the lifting and guiding effect is improved. In addition, the first air deflector can also be rotated to a state of gradually extending downwards from back to front, so that the first air deflector guides the air flow to the front and the lower.
Furthermore, in the air-conditioning indoor unit of the invention, the first air deflector has the function of shielding the air outlet at the front side of the air outlet, so that the upper edge of the air outlet can be designed to be more upper, and the second air deflector can guide air upwards at a larger uplifting angle (the upper edge of the air outlet is more upper, and the theoretical maximum uplifting angle is larger). Moreover, the air outlet area of the air outlet is larger, so that air outlet is smoother, the wind resistance is reduced, and large-air-volume air supply is facilitated.
Furthermore, in the indoor unit of an air conditioner, the second air deflector comprises an air deflector body and an air raising part, and when the second air deflector is in a front air guiding state, the air raising part can guide the air supply airflow to obliquely flow upwards and forwards so as to increase the raising angle of the air supply airflow. And the wind-raising plate of the wind-raising part is positioned at the first end of the wind deflector body, and the projection of the tail end of the wind-raising plate on the wind deflector body falls outside the wind guide surface, so that the wind-raising effect of the wind-raising plate is better.
Furthermore, the shape of the upper wall of the air duct is specially designed, and the rear flat plate section close to the fan is a straight line section, so that the air outlet stability of the fan is favorably kept. The middle arc plate section can enlarge the air outlet angle, change the air outlet direction and increase the air outlet quantity under the condition of minimum flow resistance. The outermost section of the upper wall in the air flue is a front panel section, which can be horizontal and also can have a certain upward inclination angle, so that the air outlet airflow is stable, and the flowing directivity is better. The design of the shape of the upper wall of the air duct enables the air quantity and the air flow stability to be better when the air flow is blown upwards.
The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments thereof, taken in conjunction with the accompanying drawings.

In the figure, the direction of the supply air flow is indicated by solid arrows, and the direction of the intake of ambient air is indicated by hollow arrows.
Fig. 1 is a schematic view of an air conditioning indoor unit according to an embodiment of the present invention, when a first air deflector 60 is in a closed state and a second air deflector 50 is in a front air guiding state; fig. 2 is a schematic view of the air conditioning indoor unit shown in fig. 1, when the first air deflector 60 is in an open state and the second air deflector 50 is in a front air guiding state; fig. 3 is a schematic view of the air conditioning indoor unit shown in fig. 1, when the first air guiding plate 60 is in a closed state and the second air guiding plate 50 is in a downward air guiding state.
As shown in fig. 1 to 3, an air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10, a first air guiding plate 60, and a second air guiding plate 50.
The housing 10 is provided with an air outlet 12, and the air outlet 12 faces forward and downward (that is, an outlet section of the air outlet 12 faces forward and downward, or a normal of the air outlet 12 gradually inclines downward from back to front). The air flow blown out from the inside of the casing 10 is the supply air flow. When the air conditioner is used for refrigerating, the air supply flow is cold air; when the air conditioner heats, the air supply flow is hot air. Of course, when the air conditioner has a fresh air mode, the supplied air flow can also be outdoor air.
The indoor unit of the air conditioner can be an indoor unit of an air conditioning system which performs refrigeration/heating through a vapor compression refrigeration cycle system, and specifically can be an indoor unit of a wall-mounted machine or a cabinet machine or various end machine types of a central air conditioner. For example, as shown in fig. 1, the air conditioning indoor unit is a wall-mounted air conditioning indoor unit, and includes an evaporator 20, a fan 30, and an air duct 40. The evaporator 20 is used for exchanging heat with air entering the housing 10 from the air inlet 11 to form cold air or hot air. The inlet of the air duct 40 faces the evaporator 20, and the outlet communicates with the air outlet 12. The fan 30 may be a cross-flow fan disposed at an inlet of the air duct 40 to promote air flow from the evaporator 20 to the air outlet 12.
The first and second air deflectors 60 and 50 are rotatably installed at the front and lower sides of the outlet 12, respectively, to cooperatively open and close the outlet 12, and also to guide the direction of the blowing air flow. As shown in fig. 1, the first air deflector 60 is in a closed state for shielding the front side of the air outlet 12, the second air deflector 50 is for shielding the lower side of the air outlet 12, and the first air deflector 60 and the second air deflector 50 together close the air outlet 12. The first air deflector 60 is rotatable from a closed state to an open state as shown in fig. 2 to allow the supply airflow to flow forward. It will be appreciated that the first air deflection plate 60 has a plurality of open states, differing in the angle of opening. The first air deflection plate 60 is in the open state as long as it is rotated forward from the closed state to open the front side of the outlet 12 to allow the air current to flow forward. A motor is installed in the housing 10 to drive the first air guiding plate 60 to rotate. Alternatively, the first air guiding plate 60 may be a manually rotatable structure. The air guiding effect can be changed by adjusting the opening angle of the first air guiding plate 60.
The second air guide plate 50 has an air guide surface 511 for mainly contacting with the air flow and guiding the air flow. The second air deflection plate 50 is configured to: the air outlet 12 can be rotated to a front air guiding state that the air guiding surface 511 is upward and is positioned at the lower side, so as to guide the air flow to the front, the front upper part or the front lower part, as shown in fig. 2; the air guide surface 511 is rotated to a downward air guide state located behind the air outlet 12 and facing forward, so as to guide the air flow downward, as shown in fig. 3. It can be understood that the second air guiding plate 50 is configured to guide the blowing air flow forward, upward and forward or downward, provided that the first air guiding plate 60 is rotated to the open state.
When the second air guiding plate 50 is in the downward air guiding state, the first air guiding plate 60 can be in the closed state, so that the first air guiding plate 60 and the second air guiding plate 50 together form a channel extending downward, which is convenient for guiding the air flow downward, as shown in fig. 3.
In the embodiment of the invention, the air-conditioning indoor unit has multiple air supply modes, and the air supply comfort experience of the air-conditioning indoor unit is improved. For example, during cooling operation of the air conditioner, the first air deflector 60 may be adjusted to the open state and the second air deflector 50 may be adjusted to the front air guiding state, so that the second air deflector 50 guides the supply air flow (cold air) to the front, front upper side, or front lower side. Preferably, the second air guiding plate 50 can be selected to guide the cold air to the front upper side, so that the cold air can be blown out at a larger upward-blowing angle (the included angle between the air flow blowing angle and the horizontal plane) to avoid the human body. The cold wind is scattered downwards after reaching the highest point, and a 'shower type' refrigeration experience is realized, as shown in figure 2. When the air conditioner is in heating operation, the second air deflector 50 can be selectively adjusted to be in a downward air guiding state that the air guiding surface 511 faces forward and is positioned at the rear side of the air outlet 12, so as to guide the air flow (hot air) downward, so that the hot air is directly blown to the bottom surface in a vertical downward direction, and the foot warming experience is realized, as shown in fig. 3.
Moreover, since the first air guiding plate 60 has the function of shielding the air outlet 12 at the front side of the air outlet 12, the upper edge of the air outlet 12 can be designed to be higher, which is beneficial for the second air guiding plate 50 to guide air at a larger upward angle (the higher the upper edge of the air outlet is, the larger the theoretical maximum upward angle is). Moreover, the air outlet area of the air outlet 12 is larger, and large air volume air supply is facilitated. It should be understood that the air guiding effect of the second air guiding plate 50 is only described in the front air guiding state and the lower air guiding state, and the second air guiding plate 50 can be rotated to other positions besides the front air guiding state and the lower air guiding state, so as to guide the air flow in other directions. A motor is installed in the housing 10 to drive the second air guiding plate 50 to rotate.
The air outlet 12, the first air guiding plate 60 and the second air guiding plate 50 may be all long strips with length directions parallel to the horizontal direction. The rotation axis 63 of the first air guiding plate 60 and the rotation axis 53 of the second air guiding plate 50 can be parallel to each other and parallel to the length direction of the air outlet 12. The first air guiding plate 60 may be flat or curved with its convex surface facing outward, and may be smoothly connected to the front surface of the casing 10 when in the closed position, so as to make the appearance of the air conditioning indoor unit more beautiful.
As shown in fig. 3, the second air guiding plate 50 may be arranged to be vertically disposed below the lower surface (which refers to the solid surface of the casing) of the casing 10 in the downward air guiding state. In this way, the air flow blown out from the air outlet 12 is guided by the air guiding surface 511 to flow downward from the front side of the second air guiding plate 50, and the air flow does not flow to the top and the rear side of the second air guiding plate 50, so that the top of the second air guiding plate 50 is prevented from being impacted by the air flow, and the wind resistance is increased.
As shown in fig. 1 to 3, the second air deflector 50 is rotatably mounted to the casing 10 at the rearward end thereof in the front air guiding state, and the rotating shaft 53 thereof is positioned at the lower edge of the outlet 12, so that the second air deflector 50 stands below the lower surface (solid surface) of the casing 10 in the downward air guiding state, and the entire air flow flows from the front side of the second air deflector 50. Specifically, both ends in the longitudinal direction of the rotating shaft 53 may be rotatably attached to both ends in the longitudinal direction of the housing 10, respectively.
In some alternative embodiments, the rotating shaft 53 may be spaced apart from the air guiding surface 511 and adjacent to the end (i.e., end B) of the second air guiding plate 50 facing backward when in the front wind guiding state.
In some embodiments, as shown in fig. 1-3, the rotational axis 63 of the first air deflection plate 60 can be located at the downward end of the first air deflection plate 60 when in the closed position. Therefore, when the second air guiding plate 50 is in the front air guiding state, the first air guiding plate 60 can be rotated to be parallel to the second air guiding plate 50 or to have an included angle smaller than 180 ° (as shown in fig. 2), so that the airflow flowing out of the second air guiding plate 50 is further lifted and guided by the first air guiding plate 60, and the lifting and guiding effect is enhanced. In addition, the first air guiding plate 60 can also be rotated to a state where the included angle between the first air guiding plate 60 and the second air guiding plate 50 is greater than 180 degrees (the counterclockwise rotation is continued from the state shown in fig. 2), so as to completely open the front side passage of the air outlet 12, so that the first air guiding plate 60 does not participate in air guiding, and the second air guiding plate 50 is completely used for upward air guiding, thereby reducing the air flow resistance.
Fig. 4 is a schematic view illustrating an air conditioning indoor unit according to another embodiment of the present invention, when the first air deflector 60 is in a closed state and the second air deflector 50 is in a front air guiding state; fig. 5 is a schematic view of the air conditioning indoor unit shown in fig. 4 when the first air deflector 60 is in an open state and the second air deflector 50 is in a front air guiding state; fig. 6 is a schematic view of the air conditioning indoor unit shown in fig. 4, when the first air guiding plate 60 is in a closed state and the second air guiding plate 50 is in a downward air guiding state.
As shown in fig. 4 to 6, in this embodiment, the rotating shaft 63 of the first air guiding plate 60 is located between the upper end and the lower end of the first air guiding plate 60 in the closed state, and is spaced from the upper edge of the air outlet 12. For example, the rotation shaft 63 is located at the center of the first air guiding plate 60. Therefore, when the second air guiding plate 50 is in the front air guiding state, the first air guiding plate 60 can be rotated to be parallel to the second air guiding plate 50 or to have an included angle smaller than 180 ° (as shown in fig. 5), so that the airflow flowing out of the second air guiding plate 50 is further lifted and guided by the first air guiding plate 60, and the lifting and guiding effect is improved. Further, the first air deflector 60 may be rotated to a state of gradually extending downward from the rear to the front (the counterclockwise rotation is continued from the state shown in fig. 5) so that the first air deflector 60 guides the blowing air flow to the front downward direction.
Fig. 7 is a schematic structural view of a second air deflector 50 in the indoor unit of an air conditioner according to the present invention; fig. 8 is a schematic size relationship between the wind-lifting plate 52 and the wind deflector body 51 of the second wind deflector 50 shown in fig. 7.
In some embodiments, as shown in fig. 7, the second air deflection plate 50 may include a deflection plate body 51 and a wind-raising portion. The air deflector body 51 is a main body part of the second air deflector 50, and is mounted on the casing 10 for movably connecting with the casing 10. The rotating shaft 53 is located on the air guide plate body 51. When the second air guiding plate 50 is in the front air guiding state (see fig. 2), the upward surface of the air guiding plate body 51 constitutes the air guiding surface 511, which is mainly used for guiding the air flow. The wind blowing part is formed on the wind guide surface 511, and is used for guiding the air supply flow to obliquely flow upwards when the second wind deflector 50 is in a front wind guiding state, so that the blowing angle of the air supply flow is increased, and cold wind is blown upwards at an angle closer to the vertical direction when the air conditioner is used for cooling.
As shown in fig. 7, the wind-lifting portion may include a wind-lifting plate 52 spaced apart from the wind-guiding surface 511. When the air deflector body 51 is in the front wind guiding state, the forward end and the backward end are respectively a first end (a end) and a second end (B end), as shown in fig. 2. In a direction from the second end to the first end (a direction from the end B to the end a, which is a flowing direction of the blowing air flow when the second air guiding plate 50 is in the front air guiding state), the distance between the air blowing plate 52 and the air guiding surface 511 gradually increases, so as to smoothly guide the air flow to gradually separate from the air guiding plate body 51.
As shown in fig. 7, it is preferable that the air blowing plate 52 is provided at the first end (end a) of the air guide plate body 51 to perform a focused upward blowing guide to blow upward the supply air flow when the supply air flow is near to leave the second air guide plate 50. In addition, the projection of the end (E end) of the wind-raising plate 52 far from the second end on the wind guide plate body 51 can be made to fall outside the wind guide surface 511. In other words, the air outlet end (a end) of the air deflector body 51 is retracted to the second end (B end) of the air deflector body 51 by a distance compared with the end (E end) of the air raising plate 52. It can also be understood that the end of the wind-raising plate 52 is perpendicular to the wind-guiding surface 511 of the wind-guiding plate main body 51, and the hanging part falls on the extension surface of the wind-guiding surface 511. This makes the wind-raising plate 52 more protrusive with respect to the wind deflector body 51, facilitating wind raising thereof at a larger angle.
The wind-lifting portion may further include a connecting rib (not shown), and the connecting rib is connected between the wind deflector body 51 and the wind-lifting plate 52 to realize the structural connection therebetween. The wind-raising portion and the wind deflector body 51 may be an integrally formed integral piece.
According to the embodiment of the invention, the size relationship and the relative position relationship between the wind-raising plate 52 and the wind deflector body 51 are optimally designed, so that the wind-raising effect is better. Fig. 8 is a schematic size relationship between the wind-lifting plate 52 and the wind deflector body 51 of the second wind deflector 50 shown in fig. 7.
As shown in fig. 8, the wind-lifting plate 52 may include a plate main body section 521 and an arc-shaped section 522 connected to an end of the plate main body section 521 closer to the wind deflector body 51 and having a convex surface facing the wind deflector body 51, wherein the arc-shaped section 522 is smoothly connected to the plate main body section 521 for smoothly guiding the supply air flow to the plate main body section 521, and the supply air flow is lifted and guided by the plate main body section 521.
As shown in fig. 8, the width (ED end distance) of the wind-raising plate 52 and the width (L) of the wind deflector body 51 can be set1) The ratio is between 0.3 and 0.35, preferably 1/3. A width (L) of a portion of the wind guide surface 511 outside the wind guide surface 511 projected by the wind raising plate 522) Width (L) of the air deflector body 511) The ratio of the two is between 0.08 and 0.12, preferably 0.1. The wind-raising angle θ (the included angle between the flowing direction of the supplied air after being blown out from the wind-raising plate 52 and the flowing direction of the supplied air before flowing into the surface of the wind-raising plate 52) of the wind-raising plate 52 is preferably 25 ° to 35 °, so as to ensure that the supplied air has a better wind-raising effect and avoid excessive wind resistance caused by an excessive wind-raising angle of the wind-raising part.
In some embodiments, as shown in fig. 2 and 7, the other side 512 of the air deflector body 51 facing away from the air deflecting surface 511 may be formed with a streamlined projection 5121 at a section adjacent to the first end (a end). When the second air deflector 50 is in the front air guiding state, part of the air supply airflow flows out forward from between the upper side of the air deflector body 51 and the air raising plate 52, and under the driving of the negative pressure action of the air supply airflow and the guiding of the streamline-shaped protruding portion 5121, the normal temperature air at the lower side of the air deflector body 51 can be converged into the air supply airflow to form a certain air mixing effect, so that the air supply amount is increased, the temperature of the part of the airflow is closer to the room temperature, and the human feeling is more comfortable. As previously mentioned, the air conditioning indoor unit may include the duct 40. The air duct 40 is connected to the air outlet 12 inside the housing 10, and is used for guiding the air flow to the air outlet 12.
In the embodiment of the present invention, the second air guiding plate 50 has a multi-stage wind blowing effect when in the front wind guiding state. Specifically, the surface (upper surface in this state) of the wind-lifting plate 52 departing from the wind deflector body 51 forms a wing surface structure with a large elevation angle, airflow smoothly flows after being accelerated by a fan, when the airflow passes through the wind-lifting plate 52, the upper airflow is accelerated to lift, the lift force is rapidly increased, the flow velocity of the whole airflow is promoted to be increased, the upward blowing angle is increased, a higher wind-lifting angle and speed can be rapidly reached within a very short distance, first-stage wind lifting is formed (the first-stage wind lifting process is similar to the take-off process of a carrier aircraft which performs sliding takeoff on an aircraft carrier), and the extension molded line of the wind-lifting plate 52 can be an archimedean spiral to enhance the first-stage wind lifting effect. A passage gradually expanding along the airflow direction is formed between the wind-raising plate 52 and the wind deflector body 51, and the inlet of the passage is narrow, so that the airflow enters at high speed. The passage area is gradually increased to minimize the resistance when the air flow passes through, and the high air speed is still maintained after the air flow passes through. Meanwhile, the air outlet angle gradually rises under the action of the surface (lower surface) of the air deflector 52 facing the air deflector body 51, so that the middle-layer high-speed airflow further rises to blow out the channel to form second-level air blowing. After the air flow passes through the first stage wind raising and the second stage wind raising, a negative pressure region is formed at the lower side of the air deflector body 51. The lower outlet air flow is sucked by negative pressure, changes direction, deflects upwards along the air deflector body 51, and is converged with the high-speed high-pressure air flow at the middle layer to form integral injection polymerization air flow. The upward movement of the lower layer airflow forms third-level wind raising. According to the invention, through the three-stage air raising effect, the air blowing flow on the refrigeration is gradually advanced and raised layer by layer, so that the integral large-angle air raising effect is formed.
Fig. 9 is a schematic shape view of the upper wall 41 of the air duct of the air conditioning indoor unit shown in fig. 1.
In some embodiments, as shown in fig. 9, the upper wall 41 of the air duct 40 includes a front flat plate section (ab section) extending rearward from the upper edge of the air outlet 12, a curved plate section (bc section) extending rearward from the rear end of the front flat plate section (ab section), a rear flat plate section (cd section) extending upward rearward from the rear end of the curved plate section (bc section), an arc-shaped transition section (de section) extending upward from the rear end of the rear flat plate section (cd section) first rearward, and an upper flat plate section (ef section) extending upward from the upper edge of the arc-shaped transition section (de section). By specially designing the shape of the upper wall 41 of the air duct 40, the rear flat plate section (cd section) close to the fan 30 is a straight line section, which is beneficial to keeping the air outlet stability of the fan. The middle arc plate section (bc section) can enlarge the air outlet angle, change the air outlet direction and increase the air outlet quantity under the condition of minimum flow resistance. The outermost section of the upper wall 41 of the air duct is a front panel section (ab section), which can be horizontal and also has a certain upward inclination angle, so that the air outlet flow is stable, and the flowing directivity is better. The design of the shape of the upper wall 41 of the air duct enables the air quantity and the air flow stability to be better when the air flow is blown upwards.
The inventor finds that the arc length L of the arc plate segment (bc segment)bcLength L from front plate section (ab section)abThe ratio is preferably set between 1.5 and 2.5. Length L of rear panel section (cd section)cdLength L from front plate section (ab section)abThe ratio of the above is preferably set to 0.3 to 0.6, which enhances the above effect.
