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 baffle 60 is in a closed position and an air deflector 50 is in a first position; fig. 2 is a schematic view of the indoor unit of the air conditioner shown in fig. 1, when the flap 60 is in the open position and the air deflector 50 is in the first position; fig. 3 is a schematic view of the air conditioning indoor unit of fig. 1 when the damper 60 is in the open position and the air deflector 50 is in the second position.
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 baffle 60, and an air deflector 50.
An air outlet 12 is formed in the housing 10, and the air outlet 12 faces forward and downward (that is, an outlet cross-sectional surface of the air outlet 12 faces forward and downward, or a normal line 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. The indoor unit of the air conditioner may include an evaporator 20, a blower 30, and a 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 upper end of the flap 60 is rotatably mounted to the housing 10 with the rotating shaft 63 at the upper edge of the outlet 12 so as to rotate to an open position where the front side of the outlet 12 is opened, as shown in fig. 2; or to a closed position, which blocks the front side of the outlet 12, as shown in fig. 1. When the shutter 60 is in the closed position, it is in the vertical posture or close to the vertical posture so as to be shielded on the front side of the air outlet 12, and the air supply flow cannot be blown out forward. Also, it will be appreciated that the flapper 60 has a plurality of open positions, differing in the angle of opening. The open position is provided only if the flap 60 is rotated forwardly from the closed position to open the front side of the outlet 12 to allow airflow to flow forwardly. The air guiding effect can be changed by adjusting the opening angle of the baffle 60. A motor is mounted in the housing 10 to drive the rotation of the shutter 60. Alternatively, the shutter 60 may be configured to be manually rotated.
The air guide plate 50 is rotatably mounted to the casing 10 and has an air guide surface 511 for mainly contacting with the air flow and guiding the air flow. The air deflector 50 is configured to: the air guiding plate can be rotated to a first position at the lower side of the air outlet 12 and the air guiding surface 511 is upward, so that when the baffle 60 is at the opening position, the air guiding plate 50 guides the air flow to the front, the front upper part or the front lower part, as shown in fig. 2; further, the air guide surface 511 may be rotated to a second position located below the baffle 60 and facing rearward to guide the air flow downward, as shown in fig. 3. At this time, the shutter 60 can be also in a closed state, i.e., a standing state. The air supply flow is guided downwards by the baffle 60 and the air deflector 50 from top to bottom in sequence, the guiding path is longer, and the air supply flow is ensured to be blown downwards. A motor is installed in the housing 10 to drive the air deflector 50 to rotate.
The embodiment of the utility model provides an in, because the machine has set up baffle 60 and aviation baffle 50 in the air conditioning, it has had multiple air supply mode, has promoted the machine air supply comfort nature of air conditioning and has experienced. For example, during cooling operation of the air conditioner, the damper 60 may be selectively adjusted to the open position and the air deflector 50 may be located at the first position below the air outlet 12, so that the air deflector 50 guides the supply air flow (cool air) forward, forward upward, or forward downward. Preferably, the air deflector 50 is selected to guide the cool air to the front upper side, so as to blow the cool air out at a larger upward angle (an 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 air deflector 50 can be selectively adjusted to the second position, so that the air supply flow (hot air) is guided downwards by the baffle 60 and the air deflector 50 in sequence, the hot air is directly blown to the bottom surface in a manner of approaching to the vertical direction downwards, and the foot warming experience is realized, as shown in fig. 3. Moreover, since the baffle 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 air deflector 50 to guide the 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 embodiment of the present invention only uses the first position and the second position as an example to describe the wind guiding effect of the wind deflector 50, and the wind deflector 50 can be rotated to other positions besides the first position and the second position, so as to guide the supply airflow in other directions.
The air outlet 12 and the air deflector 50 may be both long strips with the length direction parallel to the horizontal direction. The rotation axis 53 of the wind deflection plate 50 is parallel to the length direction of the wind deflection plate 50. The baffle 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 indoor unit of the air conditioner more beautiful.
As shown in fig. 3, when the air deflector 50 is in the second position and the baffle 60 is in the closed position, there is no air leakage gap between the lower end of the baffle 60 and the air deflector 50 (the air deflector 50 at this time is equivalent to an extension section of the baffle 60 extending downward), so that the air flow flowing through the rear surface of the baffle 60 flows to the rear of the air deflector 50 and continues to be guided downward by the air deflector 50. Without escaping to the front side of the air deflection plate 50. In addition, the air flow of the air supply does not flow to the top and the front side of the air deflector 50, so that the top of the air deflector 50 is prevented from being impacted by the air flow to increase the wind resistance. Specifically, the lower end of the baffle 60 may be directly lapped on the end of the air guide plate 50. In short, air leakage between the lower end of the baffle 60 and the upper end of the air guide plate 50 is prevented.
Specifically, as shown in fig. 2 and 3, the forward end of the air deflector 50 can be rotatably mounted to the housing 10 when in the first position, and the lower end of the baffle 60 is adjacent to the rotating shaft 53 of the air deflector 50 when in the closed position, so that the air deflector 50 can be located at the lower side of the baffle 60 when moving to the second position. For example, both lateral ends of the rotating shaft 53 may be rotatably connected to both lateral ends of the housing 10.
Fig. 4 is a schematic structural view of a wind deflector 50 in the indoor unit of the air conditioner shown in fig. 1; fig. 5 is a schematic size relationship diagram of the wind deflector 52 and the wind deflector body 51 of the wind deflector 50 shown in fig. 4.
In some embodiments, as shown in fig. 4, the wind deflector 50 may include a wind deflector body 51 and a wind-raising portion. The air deflector body 51 is a main body of the air deflector 50, and is mounted to the casing 10 for movable connection with the casing 10. The rotating shaft 53 is provided on the air guide plate 51. When the air deflector 50 is in the first position (see fig. 2), the upward surface of the air deflector body 51 forms the air guiding surface 511, which is mainly used for guiding the blowing 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 wind deflector 50 is at the first position, 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 refrigeration.
As shown in fig. 4, 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 first position, the forward and backward ends are respectively the first end (end a) and the second end (end B), 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 air deflector 50 is at the first position), the distance between the air deflector 52 and the air deflecting surface 511 gradually increases to smoothly guide the air flow away from the air deflector body 51.
As shown in fig. 4, it is preferable that the air deflector 52 is provided at the first end (end a) of the air deflector body 51 to perform a focused upward guide of the blowing air flow when the blowing air flow is near to leave the air deflector 50, and to blow upward. 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.
The embodiment of the utility model provides a carry out optimal design through size relation and the relative position relation to the board 52 and the aviation baffle body 51 of raising the wind, make it have better effect of raising the wind. Fig. 5 is a schematic size relationship diagram of the wind deflector 52 and the wind deflector body 51 of the wind deflector 50 shown in fig. 4.
As shown in fig. 5, 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. 5, 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 4, 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 air deflector 50 is at the first position, 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 the normal temperature air at the lower side of the air deflector body 51 can be converged into the air supply airflow under the drive of the negative pressure action of the air supply airflow and the guide of the streamline convex part 5121, so that a certain air mixing effect is formed, the air supply amount is increased, the temperature of the part of the airflow is closer to the room temperature, and the human body 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 air deflector 50 has a multi-stage wind raising effect when being in the first position. 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. The utility model discloses a tertiary effect of raising wind, the air flow of blowing advances step by step on the refrigeration, raises layer by layer, forms air-out effect on the holistic wide angle.

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.
