Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to an air outlet mechanism for an indoor unit of an air conditioner and an air conditioner. Background Art

[0002] The air outlet of the indoor unit of the air conditioner is usually a long and narrow strip-shaped opening area. Taking the wall-mounted indoor unit of the air conditioner as an example, the air outlet is usually an opening area with a large length in the horizontal direction and a small width in the height direction, and the opening area is generally located in the front lower part of the wall-mounted indoor unit of the air conditioner. However, due to the structure of the air conditioner, the width of the air outlet of the air conditioner is small and the air outlet resistance is large. Utility Model Content

[0003] The first object of the utility model is to provide an air outlet mechanism for an indoor unit of an air conditioner, so as to solve the technical problem that the air outlet of the existing air outlet has a small air volume in a zero wind sense mode.

[0004] The utility model provides an air outlet mechanism for an indoor unit of an air conditioner, comprising an air duct and a decorative plate, wherein the air duct has an air outlet, the air outlet is located at the end of the air duct along the air outlet direction, the decorative plate is arranged adjacent to the air outlet, and the length direction of the decorative plate is parallel to the length direction of the air outlet, and a first air dispersion hole is provided on the decorative plate.

[0005] By providing a first air dispersion hole on a decorative plate adjacent to the air outlet, the first air dispersion hole can be provided on the housing to achieve zero wind feeling. Moreover, when the air outlet is closed, the first air dispersion hole on the decorative plate can also be used to discharge air to achieve zero wind feeling. Alternatively, when the outer air guide door opens the air outlet, if the air outlet achieves zero wind feeling, then providing the first air dispersion hole on the decorative plate can increase the zero wind feeling air output and improve the efficiency of cooling or heating.

[0006] The beneficial effects brought by the air outlet mechanism of the indoor unit of the air conditioner of the utility model are:

[0007] In an optional technical solution, the decorative panel is an arc-shaped panel convex outward.

[0008] By configuring the decorative plate as an outwardly protruding arc-shaped plate, the airflow passing through the first air dispersing holes of the arc-shaped plate can have a larger outlet angle, thereby increasing the influence range of the air outlet of the air conditioner.

[0009] In an optional technical solution, the first air diffusion holes are perpendicular to the outer side wall of the arc-shaped plate.

[0010] By setting the first air diffusion holes to be perpendicular to the outer wall of the curved plate, that is, all the first air diffusion holes are roughly facing a certain area, if the air outlet is blocked, the air outlet of the air conditioner can only be sent out from the first air diffusion holes of the decorative plate. By setting the first air diffusion holes in the above directions, it can be achieved that the directions of the air outlet do not interfere with each other. When the thickness of the decorative plate is consistent, the airflow flowing to each first air diffusion hole passes through the first air diffusion holes of the same length, the loss of the fluid when flowing through these first air diffusion holes is consistent, and its flow rate is also more uniform.

[0011] In an optional technical solution, the decorative panel is configured to be snap-connected to the inner machine panel.

[0012] By configuring the decorative panel to be snap-fitted with the inner unit panel, the decorative panel can be manufactured separately when manufacturing the inner unit panel, and then assembled separately, thereby reducing the difficulty of manufacturing the inner unit panel. At the same time, if it is necessary to match different types, colors or patterns in the area next to the air outlet of the air conditioner inner unit, it is only necessary to select a suitable decorative panel separately.

[0013] In an optional technical solution, a clamping column is provided at both ends of the decorative panel in the length direction, and the clamping column includes a column root portion and a wedge-shaped portion fixedly connected to the column root portion, and the wedge-shaped portion is used to hook the clamping hole arranged on the inner machine panel.

[0014] By setting a clamping column, the wedge-shaped portion of the clamping column is inserted into the clamping hole and hooked into the clamping hole. When the air conditioner indoor unit is in normal use, the clamping column will not swing and the wedge-shaped portion of the clamping column will not be separated from the clamping hole, thereby improving the stability of the decorative panel installation.

[0015] In an optional technical solution, the air outlet mechanism of the indoor unit of the air conditioner also includes an inner air guide plate and an outer air guide door, the inner air guide plate is rotatably arranged on one side of the air outlet, and the outer air guide door is rotatably arranged on the other side opposite to the air outlet; the inner air guide plate is provided with a second air dispersion hole.

[0016] By rotating an outer air guide door on one side of the air outlet and setting an inner air guide plate with a second air dispersion hole on the other side, the air outlet can be closed when both the inner air guide plate and the outer air guide door are closed. If air is discharged at this time, it can be discharged from the decorative panel. Alternatively, when the outer air guide door is opened, the inner air guide plate is also opened to a certain angle to form a V-shape with the outer air guide door, and the inner air guide plate is used to disperse the air out of the air outlet to produce a zero wind effect. As for the two ends of the V-shaped space, that is, the two ends in the length direction of the air outlet, although there are no air dispersion holes to disperse the air, since the air outlet on these two end faces is generally not directly facing the user, direct air outlet will not significantly affect the user experience. Because, for wall-mounted air conditioners, their height is usually significantly higher than the user's head, while for cabinet-type air conditioner indoor units, the direction is upward or downward, and there is usually no situation where the user's limbs are directly facing the air outlet.

[0017] In an optional technical solution, the inner air guide plate includes an inner air guide shaft, and a supporting structure is provided on the inner side of the decorative plate, wherein the supporting structure has a notch portion and a rotating support portion, and the width of the notch portion is smaller than the diameter of the rotating support portion; the inner air guide shaft is rotatably supported on the rotating support portion.

[0018] By rotating and supporting the inner air guide shaft on the rotating part, the support rigidity of the inner air guide shaft of the inner air guide plate can be increased, especially when the decorative plate is arc-shaped, the rigidity of the decorative plate itself is significantly improved, which is more conducive to effectively supporting the inner air guide shaft. By providing a notch portion with a width smaller than the diameter of the rotating support portion, when actively installing the inner air guide shaft, the inner air guide shaft can be used to squeeze the notch portion, so that the width of the notch portion is increased, and then after the inner air guide shaft is inserted into the rotating support portion, the width of the notch portion is reduced to prevent the inner air guide shaft from escaping from the rotating support portion.

[0019] In an optional technical solution, the supporting structure includes a mounting plate, the mounting plate is located on the inner side of the decorative plate, and the notch portion is fixedly arranged on the mounting plate.

[0020] By fixing the mounting plate on the inner side of the decorative plate, the supporting structure can be completely retracted into the space on the rear side of the decorative plate. When the outer air guide door is closed, the supporting structure can be completely covered to prevent the supporting structure from being exposed or passing through the outer air guide door, thereby preventing the reliability of closing the air outlet of the outer air guide door and ensuring the aesthetics of the indoor unit of the air conditioner.

[0021] In an optional technical solution, along the air outlet direction, the distance between the first duct side wall and the second duct side wall forming the duct gradually increases, and one side edge of the decorative panel in the width direction is adjacent to the first duct side wall.

[0022] Along the air outlet direction, the distance between the first air duct side wall and the second air duct side wall increases, which means that the width of the air duct gradually increases, which is beneficial to reduce the speed of the air flow and thus facilitate obtaining the effect of zero wind feeling.

[0023] The second object of the utility model is to provide an air conditioner to solve the technical problem that the air outlet has a small air volume in a zero wind sense mode.

[0024] The utility model provides an air conditioner, comprising an indoor unit, wherein the indoor unit has an indoor unit panel, the air outlet is arranged on the indoor unit panel, the indoor unit panel has an air outlet, and the indoor unit also comprises the air outlet mechanism of the indoor unit of the air conditioner.

[0025] By arranging the above-mentioned air outlet mechanism for the indoor unit of the air conditioner in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned air outlet mechanism for the indoor unit of the air conditioner, which will not be described one by one here.

[0041] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0042] Embodiment 1:

[0043] Figure 1 A schematic diagram of the structure of the air outlet mechanism of the indoor unit of the air conditioner provided in the first embodiment of the utility model; Figure 2 The air outlet mechanism of the indoor unit of the air conditioner provided in the first embodiment of the utility model is Figure 1 The cross-sectional view of the state shown. Figure 1-Figure 2 As shown, the air outlet mechanism of the indoor unit of the air conditioner provided in the first embodiment of the present invention includes an air duct 100 and a decorative plate 200. The air duct 100 has an air outlet 110, and the air outlet 110 is located at the end of the air duct 100 along the air outlet direction. The decorative plate 200 is arranged adjacent to the air outlet 110, and the length direction of the decorative plate 200 is parallel to the length direction of the air outlet 110. The decorative plate 200 is provided with a first air dispersion hole 210.

[0044] Among them, in this embodiment, a wall-mounted air-conditioning indoor unit is taken as an example, but it does not prevent the product of the present application from being applied to a cabinet-type air-conditioning indoor unit. Generally speaking, the air outlet 110 of the wall-mounted air-conditioning indoor unit is mostly arranged at the front lower part or the front part of the indoor unit panel 500. The front refers to the side of the wall-mounted air-conditioning indoor unit facing the main indoor space, and the rear refers to the side of the wall-mounted air-conditioning indoor unit facing the wall on which it is hung. The bottom refers to the side of the wall-mounted air-conditioning indoor unit facing the ground. The left and right can be defined based on the above-mentioned front, rear and bottom, that is, facing the wall, the observer's left hand direction is the left side, and the observer's right hand direction is the right side.

[0045] Generally, the air outlet 110 is an open area with a larger length in the left-right direction and a smaller width in the up-down direction. In this embodiment, the length direction of the decorative panel 200 is also the left-right direction, so the length direction of the decorative panel 200 is parallel to the length direction of the air outlet 110. In this embodiment, the air outlet 110 is arranged at the front lower part of the inner unit panel 500, and the decorative panel 200 is arranged at the upper edge of the air outlet 110, that is, one side edge in the width direction of the air outlet 110. In addition, the air outlet mechanism of the indoor unit of the air conditioner is also provided with an outer air guide door 400 described later. When the outer air guide door 400 is closed, the air outlet 110 can be completely blocked, and the air conditioner cannot discharge the air heated or cooled by the indoor coil through the air outlet 110.

[0046] The first air dispersion hole 210 is a through hole that penetrates the decorative plate 200 along the wall thickness direction. When the air flows through the first air dispersion hole 210, cold air flow or hot air flow can be blown out, but the user will not feel obvious wind, that is, zero wind feeling. The first air dispersion hole 210 can be a circular hole, a rectangular hole, or an elliptical hole. It should be noted that, in some drawings used in the present application, only dozens of first air diffusion holes 210 and second air diffusion holes 310 described later are schematically shown, and the first air diffusion holes 210 and second air diffusion holes 310 in the drawings are relatively large in size, but this does not mean that only so many first air diffusion holes 210 or second air diffusion holes 310 are respectively and correspondingly arranged on the decorative plate 200 or the inner air guide plate 300. In fact, hundreds or thousands of first air diffusion holes 210 or second air diffusion holes 310 may be arranged on the decorative plate 200 or the inner air guide plate 300, nor does it mean that the size of the first air diffusion holes 210 or the second air diffusion holes 310 will be so large relative to the decorative plate 200 or the inner air guide plate 300. The above representation is adopted in the drawings mainly for the convenience of clear views.

[0047] By providing the first air dispersion hole 210 on the decorative plate 200 adjacent to the air outlet 110, the first air dispersion hole 210 can be provided on the housing to achieve zero wind feeling. Moreover, when the air outlet 110 is closed, the first air dispersion hole 210 on the decorative plate 200 can also be used to discharge air to achieve zero wind feeling. Alternatively, when the outer air guide door 400 opens the air outlet 110, if the air outlet 110 achieves zero wind feeling, then providing the first air dispersion hole 210 on the decorative plate 200 can increase the air volume with zero wind feeling and improve the efficiency of cooling or heating.

[0048] like Figure 1 and Figure 2 As shown, optionally, the decorative plate 200 is an arc-shaped plate convex outward.

[0049] The shape of the decorative plate 200 is an arc, which may be a circular arc, an elliptical arc, or even a parabola or a hyperbola.

[0050] By configuring the decorative plate 200 as an outwardly protruding arc-shaped plate, the airflow passing through the first air dispersing holes 210 of the arc-shaped plate can have a larger outlet angle, thereby increasing the influence range of the air outlet of the air conditioner.

[0051] like Figure 1 and Figure 2 As shown, optionally, the first air diffusion holes 210 are perpendicular to the outer side wall of the arc-shaped plate.

[0052] Specifically, the axis of the first air diffusion holes 210 is perpendicular to the outer wall of the arc plate. For example, when the arc plate is an arc-shaped plate, all the first air diffusion holes 210 are oriented toward the same virtual axis. Of course, in this embodiment, the arc plate can be a non-circular or elliptical arc plate.

[0053] By arranging the first air dispersion holes 210 to be perpendicular to the outer side wall of the curved plate, that is, all the first air dispersion holes 210 are roughly oriented toward a certain area, if the air outlet 110 is blocked, the air outlet of the air conditioner can only be sent out from the first air dispersion holes 210 of the decorative plate 200. By arranging the first air dispersion holes 210 in the above directions, it can be achieved that the directions of the air outlet do not interfere with each other. When the thickness of the decorative plate 200 is consistent, the airflow flowing to each first air dispersion hole 210 passes through the first air dispersion holes 210 of the same length, the loss of the fluid when flowing through these first air dispersion holes 210 is consistent, and its flow rate is also more uniform.

[0054] Figure 3 The air outlet mechanism of the indoor unit of the air conditioner provided in the first embodiment of the utility model is Figure 1 The state shown is a schematic diagram of the structure after the outer air guide door and the decorative plate are omitted; Figure 4 A schematic diagram of the structure of a decorative plate in an air outlet mechanism of an indoor unit of an air conditioner provided in Embodiment 1 of the utility model; Figure 3 and Figure 4 As shown, optionally, the decorative panel 200 is configured to be snap-connected to the inner machine panel 500 .

[0055] Specifically, the end of the decorative plate 200 can be snap-fitted with the inner machine panel 500 , that is, the inner machine panel 500 is provided with an opening above the air outlet 110 , and the decorative plate 200 can cover the opening.

[0056] By configuring the decorative plate 200 to be snap-fitted with the inner unit panel 500, the decorative plate 200 can be manufactured separately when manufacturing the inner unit panel 500, and then assembled separately, thereby reducing the difficulty of manufacturing the inner unit panel 500. At the same time, if it is necessary to match different types, colors or patterns in the area next to the air outlet 110 of the air conditioner inner unit, it is only necessary to select a suitable decorative plate 200 separately.

[0057] like Figure 3 and Figure 4As shown, optionally, a clamping column 220 is respectively provided at both ends of the decorative panel 200 in the length direction, and the clamping column 220 includes a column root portion 221 and a wedge-shaped portion 223 fixedly connected to the column root portion 221, and the wedge-shaped portion 223 is used to hook the clamping hole 510 set on the inner machine panel 500.

[0058] Specifically, in this embodiment, two clamping columns 220 are provided at one end of the decorative plate 200 in the length direction, and the two clamping columns 220 at one end are arranged along the width direction of the decorative plate 200. That is, the decorative plate 200 is provided with a total of four clamping columns 220. The column root 221 of each clamping column 220 is fixedly connected to the decorative plate 200, and the wedge-shaped portion 223 is located at the free end. When viewed along the width direction of the decorative plate 200, the wedge-shaped portion 223 is roughly a right-angled trapezoid, and the end with a larger length of the two parallel sides of the right-angled trapezoid is connected to the column root 221. For the two clamping columns 220 located at the same end, the acute angles of the right-angled trapezoids of the two wedge-shaped portions 223 are all facing the same side. For example, the two clamping columns 220 at the same end can have the acute angles of the two right-angled trapezoids facing away from the middle area in the length direction of the decorative plate 200. In other words, the side surface of the two clamping columns 220 facing the middle part in the length direction of the decorative plate 200 is a continuous plane. The direction of the wedge-shaped portion 223 is set in this way, so that when the decorative plate 200 is disassembled, a force or a bending moment is applied to the decorative plate 200 along its length direction, so that the middle part of the decorative plate 200 in the length direction is raised, so that the angles of the clamping columns 220 at both ends thereof are changed, thereby facilitating the insertion or extraction of the clamping columns 220 from the clamping holes 510. Correspondingly, the clamping holes 510 are through holes set on the inner machine panel 500.

[0059] By providing the clamping column 220, the wedge-shaped portion 223 of the clamping column 220 is inserted into the clamping hole 510 and hooked into the clamping hole 510. When the air conditioner indoor unit is in normal use, the clamping column 220 will not swing and the wedge-shaped portion 223 of the clamping column 220 will not be separated from the clamping hole 510, thereby improving the stability of the installation of the decorative panel 200.

[0060] Figure 5 A schematic diagram of the structure of the air outlet mechanism of the indoor unit of the air conditioner provided in the first embodiment of the utility model, when the outer air guide door and the inner air guide plate are both opened; Figure 6 The air outlet mechanism of the indoor unit of the air conditioner provided in the first embodiment of the utility model is Figure 3 A cross-sectional view of the state shown; Figure 7 for Figure 5 Left view of; Figure 8 The air outlet mechanism of the indoor unit of the air conditioner provided in the first embodiment of the utility model is Figure 1 The state shown is a schematic diagram of the structure after the outer air guide door is omitted; Figure 1-Figure 3 and Figure 5-Figure 8As shown, optionally, the air outlet mechanism of the indoor unit of the air conditioner also includes an inner air guide plate 300 and an outer air guide door 400, the inner air guide plate 300 is rotatably arranged on one side of the air outlet 110, and the outer air guide door 400 is rotatably arranged on the other side opposite to the air outlet 110; the inner air guide plate 300 is provided with a second air dispersion hole 310.

[0061] Taking the wall-mounted air conditioner indoor unit as an example, in this embodiment, the inner air guide plate 300 is rotatably arranged on the upper side of the air outlet 110, and the outer air guide door 400 is rotatably arranged on the lower side of the air outlet 110. More specifically, the rotation axis of the inner air guide plate 300 is located on the upper side of the air outlet 110 and parallel to the length direction of the air outlet 110, while the rotation axis of the outer air guide door 400 is located on the lower side of the air outlet 110 and parallel to the length direction of the air outlet 110. Among them, the plate-like component whose axis is parallel to the length direction of the air outlet 110, that is, the outer air guide door 400 and the inner air guide plate 300 in this embodiment, how to rotate and set on the upper side or lower side of the air outlet 110 and how to drive the basic structure of the two are common sense of technicians in the relevant technical field, and this application will not repeat them. In addition, the second air dispersion hole 310 can be a rectangular hole, a circular hole, or an elliptical hole.

[0062] By rotatably setting an outer air guide door 400 on one side of the air outlet 110 and setting an inner air guide plate 300 with a second air dispersion hole 310 on the other side, the air outlet 110 can be closed when both the inner air guide plate 300 and the outer air guide door 400 are closed. If air is discharged at this time, the air can be discharged from the decorative plate 200. Alternatively, when the outer air guide door 400 is opened, the inner air guide plate 300 is also opened to a certain angle to form a V-shaped arrangement with the outer air guide door 400, and the inner air guide plate 300 is used to disperse the air discharged from the air outlet 110, so as to produce a zero wind feeling effect. As for the two ends of the V-shaped space, that is, the two ends in the length direction of the air outlet 110, although there are no air dispersion holes to disperse the air, generally speaking, the air discharged on these two end faces is not directly toward the user, so direct air discharge will not significantly affect the user experience. Because, for a wall-mounted air conditioner, its height is usually significantly higher than the user's head, while for a cabinet-type air conditioner indoor unit, the direction is upward or downward, and the user's limbs usually do not face the air outlet directly.

[0063] In addition, if the air conditioner indoor unit is a wall-mounted air conditioner indoor unit and is in the heating state, the inner air guide plate 300 is opened and set in a roughly horizontal state. The inner air guide plate 300 can be used to partially block the hot air flow rising from the air outlet 110, reduce the flow back to the air inlet, and improve the operating efficiency of the air conditioner.

[0064] like Figure 2 , Figure 5 , Figure 6 and Figure 8As shown, optionally, the inner air guide plate 300 includes an inner air guide shaft 320, and a support structure 240 is provided on the inner side of the decorative plate 200, the support structure 240 has a notch portion 243 and a rotating support portion 241, and the width of the notch portion 243 is smaller than the diameter of the rotating support portion 241, and the inner air guide shaft 320 is rotatably supported on the rotating support portion 241.

[0065] Specifically, in this embodiment, the support structure 240 is located in the middle of the length direction of the decorative plate 200 to support the middle of the inner air guide shaft 320. The support structure 240 can be integrally formed with the decorative plate 200. The rotary support portion 241 can have an arc-shaped side wall, and the central angle of the arc is greater than 180°. Therefore, the inner air guide shaft 320 can rotate in the rotary support portion 241. The space between the ends of the arc is a notch portion 243, and the inner end of the notch portion 243 along its opening direction is connected to the rotary support portion 241.

[0066] By rotatably supporting the inner air guide shaft 320 on the rotating part, the support rigidity of the inner air guide shaft 320 of the inner air guide plate 300 can be increased, especially when the decorative plate 200 is arc-shaped, the rigidity of the decorative plate 200 itself is significantly improved, which is more conducive to effectively supporting the inner air guide shaft 320. By providing the notch portion 243 with a width smaller than the diameter of the rotating support portion 241, when the inner air guide shaft 320 is actively installed, the notch portion 243 can be squeezed by the inner air guide shaft 320 to increase the width of the notch portion 243, and then after the inner air guide shaft 320 is inserted into the rotating support portion 241, the width of the notch portion 243 is reduced to prevent the inner air guide shaft 320 from escaping from the rotating support portion 241.

[0067] like Figure 2 and Figure 6 As shown, optionally, the support structure 240 includes a mounting plate 245 , the mounting plate 245 is located on the inner side of the decorative plate 200 , and the notch portion 243 is fixedly disposed on the mounting plate 245 .

[0068] By fixing the mounting plate 245 on the inner side of the decorative plate 200, the supporting structure 240 can be completely retracted into the space on the rear side of the decorative plate 200. When the outer air guide door 400 is closed, the supporting structure 240 can be completely covered to prevent the supporting structure 240 from being exposed or passing through the outer air guide door 400, thereby preventing the reliability of the outer air guide door 400 in closing the air outlet 110, and also ensuring the aesthetics of the indoor unit of the air conditioner.

[0069] like Figure 2 and Figure 6 As shown, optionally, along the air outlet direction, the distance between the first duct side wall 120 and the second duct side wall 130 forming the duct 100 gradually increases, and one side edge of the decorative panel 200 in the width direction is adjacent to the first duct side wall 120 .

[0070] Specifically, in this embodiment, both the first air duct side wall 120 and the second air duct side wall 130 can be convex away from each other. This shape can make the airflow gradually parallel to the decorative plate 200 and the air outlet 110 when the airflow flows toward the decorative plate 200 and the air outlet 110, in other words, it becomes more and more perpendicular to the air outlet 110 and the decorative plate 200, so that the airflow speed can be effectively utilized to ensure the airflow volume.

[0071] Along the air outlet direction, the distance between the first air duct side wall 120 and the second air duct side wall 130 increases, which means that the width of the air duct 100 gradually increases, which is beneficial to reduce the speed of the air flow and thus facilitate obtaining the effect of zero wind feeling.

[0072] Embodiment 2:
