Detailed Description
The present invention will be further described with reference to the following specific embodiments and the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, it will be apparent that the invention can be practiced in many other ways than those specifically described, and that many variations and modifications can be made by one skilled in the art without departing from the spirit of the invention.
In the following description, unless otherwise specified, directional terms such as "upper", "lower", "top", "bottom", "front" and "rear" are based on the direction in which the air conditioner indoor unit is actually installed.
Referring to fig. 1 and 2, an air conditioning indoor unit 100 according to a preferred embodiment of the present invention includes a case 110, a heat exchange assembly 150 and a fan assembly 160 accommodated in the case 110. The air inlet 118 of the indoor unit 100 is located at the top side of the casing 110, and the air outlet 116 is located at the bottom side of the casing 110. When the fan assembly 160 rotates about its axis of rotation, the airflow enters from the top side of the housing 110, passes through the heat exchange assembly 150, and finally exits from the outlet vents 116 at the bottom side of the housing 110. In the preferred embodiment, the indoor unit 100 is a wall-mounted indoor unit, and the rear side of the indoor unit 100 is mounted to an indoor wall. In the installed state, the axis of rotation of the fan assembly 160 is substantially parallel to the ground.
The outlet 116 of the indoor unit 100 is elongated, for example, an elongated rectangular outlet. As shown in fig. 1, the air outlet 116 is further provided with a blade assembly 130, and the blade assembly 130 is swingably provided at the air outlet 116 by a driving mechanism, so as to orient and adjust the flow direction of the air flow sent out from the air outlet 116.
As shown in fig. 1, the casing 110 of the air conditioning indoor unit 100 includes a main body part 115 and a panel 120, the panel 120 covering a front side of the main body part 115, and in a preferred embodiment, the panel 120 is installed to be openable with respect to the main body part 115 (fig. 1 shows an opened state of the panel 120). The upper portion of the panel 120 is connected to the top of the body portion 115 by a hinge structure, thus turning the panel 120 upward and open. When the panel 120 is opened, parts of the air conditioning indoor unit 100, such as the heat exchange unit 150, the fan unit 160, and electrical components and a filter screen (not shown), are accessible from the front side of the main body part 115 of the air conditioning indoor unit 100, so that maintenance and cleaning of the components inside the air conditioning indoor unit 100 can be performed.
The body portion 115 has opposing first and second side portions, wherein a rear side of the body portion 115 may be secured to a wall by fasteners.
In particular, the panel 120 of the casing 110 of the air conditioning indoor unit 100 according to the present invention includes a front portion 121 and a coanda portion 126 connected to the front portion 121. Front portion 121 and coanda portion 126 are connected to each other at edge 128. As shown in fig. 1, the front portion 121 of the panel 120 constitutes the front side of the housing 110, and the coanda portion 126 extends from the edge 128 of the front portion 121 toward the rear side of the housing 110. The panel 120 including the front portion 121 and the additional wall portion 126 is preferably integrally formed, such as by injection molding.
The outer surface of the front part 121 is substantially flat throughout and, as shown in fig. 2, the outer surface of the front part 121 is substantially perpendicular to the ground in the mounted state. The front 121 of the panel 120 is not provided with any air outlets. The front portion 121 is substantially perpendicular to the ground in the installed state of the air conditioning indoor unit 100.
The coanda portion 126 of the panel 120 extends from the lower side edge 128 of the flat front portion 121 to the rear side of the housing 110, thereby constituting a portion of the bottom side of the housing 110. The additional wall portion 126 is arranged extending between two opposite sides of the housing 110. Preferably, between the two opposite sides of the housing 110, the air outlet 116 extends for a length equal to the length over which the additional wall portion 126 extends. It should be understood that the difference between the length of the outlet 116 and the length of the coanda 126 within the tolerance of machining is also understood to be equal. The substantial equality of the length of the outlet mouth 116 and the length of the coanda portion 126 advantageously takes full advantage of the coanda effect of the coanda portion 126 to maximize the coanda effect.
The cross-section shown in fig. 2 is perpendicular to the edge 128 where the coanda portion 126 and the front portion 121 meet, and is also perpendicular to the axis of rotation D of the fan assembly 160. As can be seen in fig. 2, the coanda portion 126 of the panel 120 is adjacent to the outlet vent 116 on the bottom side of the housing 110. The coanda portion 126 has an outwardly arched arcuate outer surface, and the outer surface of the coanda portion 126 is formed to cause coanda effect airflow or coanda effect airflow. That is, the air flow discharged from the air outlet 116 is discharged distally in the direction of the surface of the convex arc-shaped wall portion 126.
In order to form an optimum coanda effect airflow, the inventors of the present invention have studied to find that the cross-sectional shape of the attached wall portion 126 should conform to the following setting. Specifically, in a cross section perpendicular to the edge 128, that is, as shown in fig. 4, a horizontal distance extending from an intersection point B of the front portion 121 and the coanda portion 126 (the intersection point B is located at the edge 128) to the housing rear side is X, and a vertical distance extending from the intersection point B of the coanda portion 126 vertically below the housing 110 is H, where 0.21< H/X <0.3, and more preferably, H/X is 0.25. When the ratio between the vertical distance H and the horizontal distance X is kept within the above range, the air flow sent from the air outlet 116 immediately adjacent to the attached wall portion 126 will effectively form a coanda effect air flow along the surface of the arc-shaped attached wall portion 126.
In a particular embodiment, a horizontal distance X that coanda 126 extends rearwardly from the intersection B of front 121 and coanda 126 is set in the range of 75mm to 90mm, and a vertical distance H that coanda 126 extends vertically from intersection B to below housing 110 is in the range of 15mm to 30 mm. In a preferred embodiment, X is set to 82.4mm and H is set to 20.8 mm.
To ensure that the additional wall portion 126 produces the coanda effect, the height of the outlet 116 in the vertical direction in the cross-section shown in fig. 3 is at a distance H1, i.e. the distance between the two end points of the outlet 16 in the cross-section in the direction perpendicular to the ground is at a distance H1. The ratio between the height distance H1 and the height distance H of the additional wall portion 126 should be set between 1 and 2, i.e., 1. ltoreq. H1: H. ltoreq.2, preferably, H1: H is 1.5. It is found that the height and distance of the air outlet 116 set in this way can make the air flow sent out from the air outlet 116 have an optimized angle and direction of flow toward the surface of the coanda portion 126, thereby maximizing the coanda effect caused by the coanda portion 126.
Further, as shown in fig. 4, in the cross section of the air conditioning indoor unit 100, the outer surface of the coanda portion 126 includes a plurality of arc segments S1, S2 that curve arcuately toward the outside of the casing 110. Wherein the plurality of arc segments includes a first arc segment S1 proximate the front 121 of the panel 120 and a second arc segment S2 extending from the first arc segment. The second arc segment S2 is directly adjacent to the outlet 116.
Preferably, the radius of the first arc segment S1 of the coanda 126 is between 80mm and 90mm and the radius of the second arc segment S2 is in the range of 300mm to 330 mm.
In the embodiment shown in FIG. 4, the radius of the first arc segment S1 is 84.6mm, and the radius of the second arc segment S2 is 318 mm.
The first and second arc segments S1 and S2 of different radii of curvature of the outer surface of the additional wall portion 126 are joined in a smooth transition, i.e., there are no distinct protrusions or indentations between the arc segments. The radius of the first arc segment S1 that meets the front 121 of the panel 120 is significantly smaller than the radius of the second arc segment S2.
Further, as shown in fig. 1, the blade assembly 130 includes a wind guide blade 131, and the wind guide blade 131 is configured to be rotatable about a horizontal axis. The air guide blade 131 extends horizontally in parallel with the extending direction of the coanda portion 126. In the closed state, the wind-guiding blade 131 substantially covers the wind outlet 116.
Preferably, the blade assembly 130 includes one or two wind guide blades 131. When the blade assembly 130 has two wind guiding blades 131, it is preferable that the two wind guiding blades 131 have equal widths.
In order to maximize the coanda effect airflow, the distance between the end of the vane assembly 130 closest to the coanda portion 126 of the panel 120 and the end of the vane assembly 130 furthest from the coanda portion 126 in a cross section of the air conditioning indoor unit 100 perpendicular to the connecting edge of the coanda portion 126 and the front portion 121 is L1, and L1 should be smaller than the horizontal distance X that the coanda portion 126 extends from the intersection point B to the rear side.
Specifically, when the blade assembly 130 has one air guiding blade 131, as shown in fig. 5A, the distance L1 is a straight distance between both end portions of the air guiding blade 131 in a cross section perpendicular to the connecting edge of the coanda portion 126 and the front portion 121. As shown in fig. 5B, when the blade assembly 130 is composed of a plurality of wind guide blades 131, the distance L1 is a distance between ends of two wind guide blades 131 farthest apart in the cross section of the blade assembly 130 in its closed state. For example, when there are two wind guide blades 131, the distance L1 is the distance between the front end of the front wind guide blade 131 and the rear end of the rear wind guide blade 131.
In addition, the wind guide blade 131 in the blade assembly 130 can swing around the horizontal axis to open the wind outlet 116. As shown in fig. 2, when the air guide blade 131 swings downward at an angle a of 5 degrees with respect to the horizontal plane, the coanda effect airflow caused by the additional wall portion 126 is the strongest. For this reason, the controller of the air conditioning indoor unit 100 according to the present invention may control the air guide blade 131 to rotate and stop at the angle a to provide the strongest coanda airflow. However, it should be understood that at other opening angles of the air guiding blade 131, the coanda portion 126 can still cause the airflow to perform the coanda motion.
On the other hand, fig. 6 is a schematic cross-sectional view of an air conditioning indoor unit having two air guide blades 131 according to another preferred embodiment of the present invention. As a result of research, in the indoor unit 100 having the two air guide blades 131 at the outlet 116, in order to maximize the effect of the coanda portion 126, the position of the air guide blade 131 is set such that when the two air guide blades 131 are opened at the same predetermined angle, the end point of the air guide blade 131 close to the coanda portion and the intersection point B are on the circumference of the same circle M. The radius of the imaginary circle M is in the range of 700 mm-800 mm, and preferably 750 mm. Further, if the radius of the imaginary circle M is large, the coanda effect airflow caused by the coanda portion 126 blows farther.
According to the air conditioning indoor unit 100 of the present invention, the panel 120 of the casing 110 includes the coanda portion 126, and the coanda portion 126 is sized and shaped to advantageously maximize the coanda effect of the air flow sent out from the outlet 116, thereby preventing the air conditioning flow from directly blowing on the human body and improving comfort. The coanda effect airflow caused by the additional wall 126 is sent out horizontally and forwards on the lower plane of the indoor unit 110, so that the air supply uniformity is better, and the indoor temperature can be uniformly increased or decreased.
In the air conditioning indoor unit 100 according to the present invention, the front portion 121 is perpendicular to the ground, and the coanda portion 126 is provided toward the rear side of the casing 110 with respect to the entire front portion 121, so that the space utilization efficiency inside the casing 110 of the air conditioning indoor unit 100 is high.
Although the present invention has been disclosed in terms of the preferred embodiment, it is not intended to limit the invention, and variations and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention. Therefore, any modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are within the protection scope defined by the claims of the present invention, unless the technical essence of the present invention departs from the content of the present invention.
