Detailed ways

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

First embodiment

Referring to Figures 1, 2, 3 and 4, an embodiment of the present invention provides an air guide mechanism 100, which is applied to an air conditioner and used to guide the air outlet direction of the air conditioner. It can realize air supply in a small range and can accurately control the direction of air supply in a small range to adjust the position where the air is blown out, which is convenient, fast, practical and reliable.

The air guide mechanism 100 includes a housing 110, a flow diversion guide block 120, and a motion component 130. The flow diversion guide block 120 and the motion component 130 are both installed in the housing 110. The flow diversion guide block 120 is used to divide the airflow into multiple streams in the housing 110. The multiple streams of air are then merged into one stream under the action of the housing 110 and output to the outside. The cross-sectional area of the merged airflow is small, and air can be supplied in a small range. In this process, the motion component 130 can drive the flow diversion guide block 120 to move to adjust the air volume of the multiple streams of air, so that the air outlet direction after the multiple streams of air are merged changes, thereby adjusting the direction of air supply in a small range.

It is worth noting that the housing 110 is provided with an air outlet slot 111, and a plurality of extension plates 112 are provided inwardly extending from the opening of the air outlet slot 111. The extension plates 112 are used to guide the airflow so that multiple airflows can converge into one. Multiple extension plates 112 are combined to form an air outlet 113, and the converged airflow is output to the outside through the air outlet 113 to achieve air supply in a small range. The diversion guide block 120 is slidably arranged in the air outlet slot 111, and forms a plurality of air ducts with the side walls of the air outlet slot 111, and the plurality of air ducts are connected to the air outlet 113, and each air duct is used to allow an airflow to pass through. The diversion guide block 120 divides the airflow into multiple streams, and the multiple airflows are output through multiple air ducts, and converge into one stream under the action of the plurality of extension plates 112, and are output to the outside from the air outlet 113. The motion component 130 is installed in the shell 110 and connected to the diversion guide block 120. The motion component 130 can drive the diversion guide block 120 to move in a direction parallel to the plane where the air outlet 113 is located to adjust the cross-sectional area of each air duct, thereby adjusting the air volume of the air flow output by each air duct, and then adjusting the air outlet direction after multiple air flows converge.

In this embodiment, there are two air ducts, namely the first air duct 140 and the second air duct 150, and there are two extension plates 112, one of which is used to guide the airflow output from the first air duct 140, and the other extension plate 112 is used to guide the airflow output from the second air duct 150. However, this is not limited to this. In other embodiments, the number of air ducts and extension plates 112 can be three or four, and the number of air ducts and extension plates 112 is not specifically limited.

It should be noted that the air outlet slot 111 is relatively provided with a first side wall 114 and a second side wall 115, the flow splitting guide block 120 and the first side wall 114 form a first air duct 140, and the flow splitting guide block 120 and the second side wall 115 form a second air duct 150. The motion component 130 can drive the flow splitting guide block 120 to approach the first side wall 114 or the second side wall 115 to adjust the cross-sectional area of the first air duct 140 and the second air duct 150, thereby controlling the air volume of the airflow blown out from the first air duct 140 and the second air duct 150, and then adjusting the flow direction of the airflow blown out from the first air duct 140 and the second air duct 150 after converging, that is, adjusting the final air supply direction.

It is worth noting that the first side wall 114 and the second side wall 115 are both located on a vertical plane or a horizontal plane. If the first side wall 114 and the second side wall 115 are both located on a vertical plane, the diversion guide block 120 moves in the horizontal direction, at which time the line connecting the midpoint of the first air duct 140 and the midpoint of the second air duct 150 is a horizontal line, and the diversion guide block 120 can control the air supply direction to be adjusted in the left and right directions; if the first side wall 114 and the second side wall 115 are both located on a horizontal plane, the diversion guide block 120 moves in the vertical direction, at which time the line connecting the midpoint of the first air duct 140 and the midpoint of the second air duct 150 is a vertical line, and the diversion guide block 120 can control the air supply direction to be adjusted in the up and down directions. In this embodiment, the first side wall 114 and the second side wall 115 are both located on a vertical plane, and the air supply direction after confluence can be adjusted in the left and right directions.

In this embodiment, one extension plate 112 is connected to the first side wall 114, and the other extension plate 112 is connected to the second side wall 115. One extension plate 112 is used to guide the airflow blown out of the first air duct 140, and the other extension plate 112 is used to guide the airflow blown out of the second air duct 150, so that the two airflows converge into one in the air outlet 113 and blow out to supply air.

Specifically, one extension plate 112 is arranged at a first obtuse angle with the first side wall 114, and the other extension plate 112 is arranged at a second obtuse angle with the second side wall 115, and the first obtuse angle and the second obtuse angle are both within the range of 95 degrees to 115 degrees. Reasonable first obtuse angle and second obtuse angle can reduce the resistance to airflow, improve the guiding effect, and reduce the recoil force when the two airflows converge, so that the two airflows can converge smoothly. In this embodiment, the first obtuse angle and the second obtuse angle are the same in size and are both 105 degrees.

It is worth noting that the air outlet slot 111 is also relatively provided with a third side wall 116 and a fourth side wall 117, and the first side wall 114, the third side wall 116, the second side wall 115 and the fourth side wall 117 are connected end to end. The third side wall 116 is provided with a through hole 118, and the motion component 130 passes through the through hole 118 and is fixedly connected to the flow diversion guide block 120 to drive the flow diversion guide block 120 to move from the first side wall 114 to the second side wall 115, thereby adjusting the air supply direction.

In this embodiment, a guide groove 119 is opened on the fourth side wall 117, and the guide groove 119 extends from the first side wall 114 to the second side wall 115. The diverter guide block 120 is slidably set in the guide groove 119. The diverter guide block 120 can slide in the guide groove 119. The guide groove 119 can limit the position and movement direction of the diverter guide block 120 to prevent the diverter guide block 120 from sliding sideways or tilting.

It should be noted that the motion assembly 130 includes a driving member 131 and a transmission member 132. The driving member 131 is installed in the housing 110 and is connected to the flow diversion guide block 120 through the transmission member 132. The driving member 131 is used to provide power, and the transmission member 132 can transmit the power output by the driving member 131 to the flow diversion guide block 120 to drive the flow diversion guide block 120 to move.

In this embodiment, the driving member 131 is a motor, and the transmission member 132 includes a gear 133 and a rack 134. The driving member 131 is connected to the gear 133, and the rack 134 is fixedly connected to the flow-dividing guide block 120 and meshes with the gear 133. The driving member 131 drives the gear 133 to rotate, thereby driving the rack 134 to move, and further driving the flow-dividing guide block 120 to move in the direction from the first side wall 114 to the second side wall 115.

Please refer to Figures 5, 6 and 7 (the hollow arrows in the figures indicate the direction of airflow, and the dotted line is the normal to the plane where the air outlet 113 is located). When the diversion guide block 120 is located at the center position of the first side wall 114 and the second side wall 115, the cross-sectional area of the first air duct 140 is the same as the cross-sectional area of the second air duct 150, that is, the air volume of the airflow blown out from the first air duct 140 is the same as the air volume of the airflow blown out from the second air duct 150. The two airflows converge under the guidance of the two extension plates 112. At this time, since the air volume of the two airflows is the same, the direction of the airflow formed after the two airflows converge is the normal direction of the plane where the air outlet 113 is located.

When the diversion guide block 120 approaches the first side wall 114, the cross-sectional area of the first air duct 140 decreases, and the cross-sectional area of the second air duct 150 increases, that is, the volume of the airflow blown out through the first air duct 140 decreases, and the volume of the airflow blown out through the second air duct 150 increases. The two air flows converge under the guidance of the two extension plates 112. At this time, due to the different volumes of the two air flows, the direction of the air flow formed after the two air flows converge will be inclined toward the direction close to the first side wall 114.

When the diversion guide block 120 approaches the second side wall 115, the cross-sectional area of the second air duct 150 decreases, and the cross-sectional area of the first air duct 140 increases, that is, the volume of the airflow blown out through the second air duct 150 decreases, and the volume of the airflow blown out through the first air duct 140 increases. The two air flows converge under the guidance of the two extension plates 112. At this time, due to the different volumes of the two air flows, the direction of the air flow formed after the two air flows converge will be inclined toward the direction close to the second side wall 115.

Specifically, the direction of the airflow formed after the two airflows converge is set at a preset angle with the normal direction of the plane where the air outlet 113 is located. The size of the preset angle will change with the movement of the diverter guide block 120. If the diverter guide block 120 abuts against the first side wall 114, the cross-sectional area of the first air duct 140 is zero, and the cross-sectional area of the second air duct 150 is the largest. At this time, the preset angle is the largest, and the direction of the converging airflow is inclined toward the direction close to the first side wall 114; if the diverter guide block 120 is located at the center of the first side wall 114 and the second side wall 115, the preset angle is the smallest, and the direction of the converging airflow is perpendicular to the plane where the air outlet 113 is located; if the diverter guide block 120 abuts against the second side wall 115, the cross-sectional area of the second air duct 150 is zero, and the cross-sectional area of the first air duct 140 is the largest. At this time, the preset angle is the largest, and the direction of the converging airflow is inclined toward the direction close to the second side wall 115.

The air guide mechanism 100 described in the embodiment of the present invention has a housing 110 provided with an air outlet slot 111, and the opening of the air outlet slot 111 is extended inwardly to be provided with a plurality of extension plates 112, and the plurality of extension plates 112 are combined to form an air outlet 113, a flow diversion guide block 120 is slidably arranged in the air outlet slot 111, and forms a plurality of air ducts with the side wall of the air outlet slot 111, and the plurality of air ducts are all connected with the air outlet 113, and a motion component 130 is installed in the housing 110 and connected with the flow diversion guide block 120, and the motion component 130 can drive the flow diversion guide block 120 to move in a direction parallel to the plane where the air outlet 113 is located, so as to adjust the cross-sectional area of each air duct. Compared with the prior art, the air guide mechanism 100 provided by the present invention can realize small-range air supply and can accurately control the direction of small-range air supply to adjust the position where the wind is blown out, which is convenient, fast, practical and reliable.
