The following describes the air deflector 1 for the air conditioner 1000 according to the embodiment of the present disclosure with reference to Figures 1-5.
As shown in Figure 1 and Figure 3, the air deflector 1 has a plurality of through holes 11 penetrating the air deflector in a thickness direction of the air deflector, and a boundary 12 extending in a length direction thereof (a left-right direction as shown in Figure 1); when the air deflector 1 closes the air outlet 2 of air conditioner 1000, the centerline of the through holes 11 above the boundary 12 (as shown in Figure 3) extends upwards at certain angle, while the centerline of the through holes 11 below the boundary 12 (as shown in Figure 3) extends downwards at certain angle in the direction from the inside (the side of air deflector 1 toward the inside of the air conditioner 1000) to the outside (the side of air deflector 1 toward the indoor space).
It should be noted that, as shown in Figure 1, Figure 3 and Figure 5, air conditioner 1000 may be set to breeze mode and breezeless mode. When the breezeless mode is activated by the user, the air deflector 1 may be turned to the position on which the air outlet 2 of air conditioner 1000 is closed, so that the air will flow through the through holes 11 on the air deflector 1 for the air conditioner 1000 first before entering the indoor space; when the air flows through the through holes 11 above the boundary 12 of the air deflector 1, it will flow upwards from the horizontal direction under the guidance of the through holes 11; when the air flows through the through holes 11 below the boundary 12 of the air deflector 1, it will flow downwards from the horizontal direction under the guidance of the through holes 11, so that the air from the air outlet 2 of the air conditioner 1000 is dispersed further, therefore preventing a large amount of air being blown directly to the user, and improving the breezeless experience of the users.
The air deflector 1 for the air conditioner 1000 according to the embodiment of the present disclosure is provided with the plurality of through holes 11 through the thickness of its air deflector 1, therefore the centerline of the through holes 11 above the boundary 12 extends upwards at certain angle while the centerline of the through holes 11 below the boundary 12 extends downwards at certain angle in the direction from the inside to the outside of the air deflector 1, so that a portion of the air flow moves upwards from the horizontal direction, while another portion moves downwards from the horizontal direction under the guidance of the through holes 11 on the air deflector 1 when the breezeless mode is activated by the user, thus preventing a large amount of air being blown directly toward the users, which improves the breezeless experience of the users, and makes them more comfortable.
According to some embodiments of the present disclosure, and as shown in Figure 2 and Figure 3, the distance between the upper edge and the lower edge of the air deflector is L1, and the distance between the boundary and the upper edge of the air deflector is L2, wherein L1 and L2 satisfy: 2/5≤L2/L1≤2/3. Thus, the quantity of through holes 11 above the boundary 12 is different from that of through holes 11 below the boundary 12, for the convenience of controlling and defining the air flowing upwards from the air deflector 1 and the air flowing downwards from the air deflector 1.
According to some embodiments of the present disclosure, and as shown in Figure 2 and Figure 3, the distance between the upper edge and the lower edge of the air deflector 1 is L1, and the distance between the boundary 12 and the upper edge of the air deflector 1 is L2, wherein L1 and L2 satisfy: 3/5≤L2/L1≤2/3. Thus, the quantity of through holes 11 above the boundary 12 is different from that of through holes 11 below the boundary 12, for the convenience of controlling and defining the air flowing upwards from the air deflector 1 and the air flowing downwards from the air deflector 1.
It should be noted that the L1 between the upper edge and the lower edge of the air deflector 1 is the vertical distance between the upper edge and the lower edge of the air deflector 1, while the distance L2 between the boundary 12 and the upper edge of the air deflector 1 is the vertical distance between the boundary 12 and the upper edge of the air deflector 1 in case the air deflector 1 is of planar construction; the distance L1 between the upper edge and the lower edge of the air deflector 1 is the distance between the upper edge and the lower edge of the air deflector 1 when the air deflector 1 is unfolded fully to horizontal state, while the distance L2 between the boundary 12 and the upper edge of the air deflector 1 is the distance between the boundary 12 and the upper edge of the air deflector 1 when the air deflector 1 is unfolded fully to horizontal state in case the air deflector 1 is of curved surface construction.
According to some embodiments of the present disclosure, and as shown in Figure 1, Figure 3 and Figure 5, the angle between the centerline of the through holes 11 above the boundary 12 and the horizontal plane is α, wherein α satisfy: 0<α≤15°. Thus, after passing through the through holes 11 above the boundary 12, the air can flow upwards from the horizontal direction, thus preventing the air being blown directly toward the user, and offering the users breezeless comfort. In addition, it can prevent the air forming the circular flow close to the wall after flowing upwards from the air deflector 1, affecting the breezeless experience.
It should be noted that the angle α between the centerline of the through holes 11 above the boundary 12 and the horizontal plane is the angle when the air deflector 1 closes the air outlet 2 of the air conditioner 1000.
According to some embodiments of the present disclosure, α satisfies: 0<α≤10°. Thus, it can prevent further the air being blown directly toward the user, so that the users can feel breezeless comfort. In addition, it can prevent the air forming the circular flow close to the wall after flowing upwards from the air deflector 1, affecting the breezeless experience.
According to some embodiments of the present disclosure, α satisfies: 3°≤α≤5°. Thus, it can prevent further the air being blown directly toward the user, so that the users can feel breezeless comfort. In addition, it can prevent the air forming the circular flow close to the wall after flowing upwards from the air deflector 1, affecting the breezeless experience.
According to some embodiments of the present disclosure, and as shown in Figure 1, Figure 3 and Figure 5, the angle between the centerline of the through holes 11 below the boundary 12 and the horizontal plane is β, wherein β satisfies: 0<β≤45°. Thus, after passing through the through holes 11 below the boundary, the air can flow downwards from the horizontal direction, which prevents the air being blown directly toward the user, and thereby increases the breezeless experience of the user.
It should be noted that the angle β between the centerline of the through holes 11 below the boundary 12 and the horizontal plane is the angle when the air deflector 1 closes the air outlet 2 of the air conditioner 1000.
According to some embodiments of the present disclosure, β satisfies: 0<β≤20°. Thus, after passing through the through holes 11 below the boundary 12, the air can flow further downwards from the horizontal direction, which prevents the air being blown directly toward the user, and thereby increases the breezeless experience of the users further.
According to some embodiments of the present disclosure, and as shown in Figure 1 and Figure 4, the diameter of the through holes 11 is D, wherein D satisfies: 1mm≤D≤3mm. Thus, the through holes 11 can realize deflection and guidance of the air flow, which reduces the energy loss of the air flow in the guide process, lowers the energy consumption of the air conditioner 1000 in breezeless mode and improves the breezeless effect of the air conditioner 1000.
According to some embodiments of the present disclosure, D satisfies: 1.3mm≤D≤2.5mm. Thus, the through holes 11 can realize deflection and guidance of the air flow, which reduces the energy loss of the air flow in the guide process, lowers the energy consumption of the air conditioner 1000 in breezeless mode and improves the breezeless effect of the air conditioner 1000.
According to some embodiments of the present disclosure, the diameters of the plurality of through holes 11 are the same, which thereby simplifies the manufacturing procedure of the through holes 11, shortens the production cycle of the air deflector 1, lowers the production costs of the air conditioner 1000 and enhances the aesthetics of the air conditioner 1000.
According to some embodiments of the present disclosure, and as shown in Figure 1, Figure 3 and Figure 4, the diameters of the through holes 11 above the boundary 12 increases gradually, while the diameters of the through holes 11 below the boundary 12 decreases gradually in the direction from top to bottom (as shown in Figure 3). Therefore, in the direction from top to bottom, the air flow through the through holes 11 will increase gradually when it passes through the through holes 11 above the boundary 12, and will decrease gradually when it passes through the through holes 11 below the boundary 12, which thereby reduces the energy loss of air flow when passing through the through holes 11, lowers the energy consumption of the air conditioner 1000 and enhances the aesthetics of the air conditioner 1000. Meanwhile, it can prevent the air forming circular flow close to the wall after flowing upwards from the air deflector 1, affecting the breezeless experience of the user.
The following describes the housing assembly 100 as specified in the embodiment of the present disclosure with reference to the Figures 1-5.
As shown in Figure 1 and Figure 3, the housing assembly 100 as specified in the embodiment of the present disclosure comprises the air deflector 1.
The housing assembly 100 for the air conditioner 1000 according to the embodiment of the present disclosure is provided with the plurality of through holes 11 through the thickness of its air deflector 1, therefore the centerline of the through holes 11 above the boundary 12 extends upwards at certain angle while the centerline of the through holes 11 below the boundary 12 extends downwards at certain angle in the direction from the inside to the outside of the air deflector 1, so that a portion of the air flow moves upwards from the horizontal direction, while another portion moves downwards from the horizontal direction under the guidance of the through holes 11 on the air deflector 1 when the breezeless mode is activated by the user, thus preventing a large amount of air being blown directly toward the users, which improves the breezeless experience of the users, and makes them more comfortable.
The following describes the air conditioner 1000 as specified in the embodiment of the present disclosure with reference to the Figures 1-5.
As shown in Figure 1 and Figure 3, the air conditioner 1000 as specified in the embodiment of the present disclosure comprises the housing assembly 100.
The air conditioner 1000 according to the embodiment of the present disclosure is provided with the plurality of through holes 11 through the thickness of its air deflector 1, therefore the centerline of the through holes 11 above the boundary 12 extends upwards at certain angle while the centerline of the through holes 11 below the boundary 12 extends downwards at certain angle in the direction from the inside to the outside of the air deflector 1, so that a portion of the air flow moves upwards from the horizontal direction, while another portion moves downwards from the horizontal direction under the guidance of the through holes 11 on the air deflector 1 when the breezeless mode is activated by the user, thus preventing a large amount of air being blown directly toward the users, which improves the breezeless experience of the users, and makes them more comfortable.
The following describes the air conditioner 1000 as specified in the specific embodiment of the present disclosure with reference to the Figures 1-5. It should be understood that the following description is only illustrative and is used to interpret the present disclosure but should not be construed as restrictions on the present disclosure.
As shown in Figure 1, Figure 3 and Figure 4, the air conditioner 1000 of the present disclosure comprises the housing assembly 100, the pedestal 4, the front panel 3 and the rear panel, where the housing assembly 100 also comprises the air deflector 1 which is connected to the housing assembly 100 through the hook 13.
As shown in Figure 1 and Figure 3, the housing assembly 100 is provided with the air outlet 2 which is located at the bottom (the bottom as shown in Figure 3) of the front side (the front side as shown in Figure 3) of the air conditioner 1000, and extends in the length direction (the left-right direction as shown in Figure 1) of the air conditioner 1000.
As shown in Figures 1-3, the air deflector 1 extends in the length direction (the left-right direction as shown in Figure 1) of the air conditioner 1000, and is used to close the air outlet 2 of the air conditioner 1000.
As shown in Figures 1-3, the air deflector 1 has the plurality of through holes 11 penetrating the air deflector in the thickness direction, and the boundary 12 extending in its length direction, where the centerline of the through holes 11 above the boundary 12 (as shown in Figure 3) extends upwards at certain angle while the centerline of the through holes 11 below the boundary 12 (as shown in Figure 3) extends downwards at certain angle in the direction from the inside (the side of air deflector 1 toward the air conditioner 1000) to the outside (the side of air deflector 1 toward the indoor space) of the air deflector 1.
As shown in Figures 1-3, the cross section of the air deflector 1 is arc-shaped, the distance of arc section between the upper edge and the lower edge of the air deflector 1 is L1, the distance of arc section between the boundary 12 and the upper edge of the air deflector 1 is L2, wherein L1 and L2 satisfy: 3/5≤L2/L1≤2/3. Thus, the quantity of through holes 11 above the boundary 12 is different from that of through holes 11 below the boundary 12, for the convenience of controlling and defining the air flowing upwards from the horizontal direction and the air flowing downwards from the horizontal direction.
As shown in Figure 1, Figure 3 and Figure 4, in the direction from top to bottom, the air flow through the through holes 11 will increase gradually when it passes through the through holes 11 above the boundary 12, and will decrease gradually when it passes through the through holes 11 below the boundary 12, which thereby reduces the energy loss of air flow when passing through the through holes 11, lowers the energy consumption of the air conditioner 1000 and enhances the aesthetics of the air conditioner 1000. Specifically, the diameter of the through holes 11 is D, wherein D satisfies: 1.3mm≤D≤2.5mm.
As shown in Figure 1, Figure 3 and Figure 5, the angle between the centerline of the through holes 11 above the boundary 12 and the horizontal plane is α, wherein α satisfies: 0<α≤10°, and the angle between the centerline of the through holes 11 below the boundary 12 is β, wherein β satisfies: 0<β≤20°. Thus, after the air flows through the through holes 11 above and below the boundary 12, it can flow upwards and downwards from the air deflector respectively, which thus prevents the air being blown directly toward the user, and thereby offers the users a breezeless comfortable environment.
