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 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 upper end of the baffle is rotatably arranged on the shell, and the rotating shaft of the baffle is positioned at the upper edge of the air outlet so as to rotate to an opening position for opening the front side of the air outlet or a closing position for shielding the front side of the air outlet; and
a wind deflector rotatably mounted to the housing and configured to:
the baffle plate can rotate to a first position which is positioned at the lower side of the air outlet and enables the air guide surface of the air outlet to face upwards, so that when the baffle plate is positioned at the opening position, the air guide plate guides the air flow of the air supply to the front, the front upper part or the front lower part;
the air guide surface can rotate to a second position which is positioned at the rear side of the air outlet and enables the air guide surface to face forwards, so that the air supply flow is guided downwards.
Optionally, the air deflector is configured to be vertically disposed below the lower surface of the housing when the air deflector is in the second position.
Optionally, the rearward end of the air deflector when in the second position is rotatably mounted to the housing with its axis of rotation at the lower edge of the outlet.
Optionally, when the baffle is in the closed position and the air deflector is in the first position, the baffle and the air deflector close the air outlet together.
Optionally, the air deflection plate comprises: the air deflector body is arranged on the shell, and when the air deflector is positioned at the first position, the upward surface of the air deflector body forms an air guide 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 air guide plate is positioned at the first position.
Optionally, the wind raising part comprises a wind raising plate arranged at an interval with the wind guide surface; when the air deflector body is located at the first position, the forward end and the backward end are respectively a first end and a second end, and the distance between the air raising plate and the air guide 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 air outlet and the air deflector are both long strips with length directions parallel to the horizontal direction.
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 conditioner indoor unit is provided with the baffle and the air deflector, so that multiple air supply modes are realized, and the air supply comfort experience of the air conditioner indoor unit is improved. When the air conditioner operates in a refrigerating mode, the baffle can be selectively adjusted to the opening position, and the air deflector is located at the first position on the lower side of the air outlet, so that the air deflector can guide air flow (cold air) to the front, the front upper side or the front lower side. For example, the air deflector can be selected to guide cold air to the front upper part 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 air deflector can be selectively adjusted to a second position which is positioned at the rear side of the air outlet and the air guide surface faces forward, so that air flow (hot air) is guided downwards by the air deflector and the baffle plate together, the hot air is directly blown to the bottom surface close to the vertical direction downwards, and foot warming experience is realized.
Furthermore, the baffle plate 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 air guide plate can guide air upwards at a larger uplifting angle (the upper edge of the air outlet is closer to the upper side, 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 the air conditioner, the air deflector comprises an air deflector body and the air raising part, and when the air deflector is located at the first position, 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.

Fig. 1 is a schematic view of an air conditioning indoor unit according to an embodiment of the present invention, when a damper 60 is in a closed position and a louver 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 a wind deflector 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. 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 behind the outlet 12 so as to face forward, thereby guiding 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 baffle 60 and the air deflector 50 together form a downwardly extending channel for directing the supply air flow downwardly. It should be understood that the wind guiding effect of the wind deflector 50 is only described by taking the first position and the second position as an example in the embodiment of the present invention, 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. A motor is installed in the housing 10 to drive the air deflector 50 to rotate.
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, the air deflector 50 may be configured to be vertically disposed below the lower surface (referring to the solid surface of the casing) of the casing 10 when it is in the second position. In this way, the air flow blown out from the air outlet 12 is guided by the air guide surface 511 to flow downward from the front side of the air deflector 50, and the air flow does not flow to the top and the rear side of the air deflector 50, so that the top of the air deflector 50 is prevented from being impacted by the air flow, and the wind resistance is increased.
As shown in fig. 2 and 3, the rearward end of the air deflector 50 may be rotatably mounted to the casing 10 when in the second position, and the rotating shaft 53 may be located at the lower edge of the outlet 12, so that the air deflector 50 may be vertically disposed below the lower surface (solid surface) of the casing 10 when in the second position, and the entire blowing air flow may flow through the front side of the 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 rotation axis may be spaced from the air guiding surface 511 and adjacent to the end (i.e. end B) of the air guiding plate 50 facing backwards when in the first position.
In the embodiment of the invention, as the air-conditioning indoor unit is provided with the baffle 60 and the air deflector 50, 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 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 a second position at the rear side of the air outlet 12, so that the air deflector 50 and the baffle 60 together guide the air flow (hot air) downwards, the hot air is ensured to be directly blown to the bottom surface vertically downwards, and the foot warming experience is realized, as shown in fig. 3. The air deflector 50 and the baffle 60 together guide the air to flow downwards and blow, and the guiding force is stronger.
Further, in the embodiment of the present invention, 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 more upward, which is beneficial for the air deflector 50 to guide the air at a larger upward angle (the more upward 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.
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.
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. 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, when the air deflector 50 is located at the first position, the multi-stage wind-raising effect is achieved. 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. 6 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. 6, 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.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
