Blowout panel and air conditioning indoor unit

The present invention relates to a blowout panel and an air conditioning indoor unit including the blowout panel.

Conventionally, an indoor unit body internally provided with an axial flow fan whose rotation axis extends along the vertical direction, and a blowout port provided below the indoor unit body and provided with a guide blade inside And a blowout panel having the

In the above-mentioned air conditioning indoor unit, in order to increase the blowing area by the air outlet, in consideration of the convenience of arrangement, it has a rectangular outer frame and a rectangular inner frame, and is surrounded by the outer frame and the inner frame. It is conceivable to adopt a blowout panel having a tapered polygonal blowout.

However, in this case, the air flow generated from the axial flow fan is less likely to be blown out to the corner of the blowout port, and the blowout by the blowout port tends to be uneven.

In the above case, it is also necessary to consider how the guide vanes are attached to the blowout panel with a simple configuration.

Also, conventionally, there are air treatment devices connected by a duct to a polygonal outlet panel. The spiral air flow discharged from the air blowing component in the air processing apparatus is blown to the blowout panel through the duct. In that case, it becomes difficult for the spiral air flow to be blown out to the corner of the blowout port, and the blowout by the blowout port tends to be uneven.

In order to solve said technical subject, the blowing panel has an outer frame and an inner frame. An outer frame and an inner frame enclose a polygonal outlet. Guide vanes are provided in the blowout port. The blowout panel is provided with a link. The link is offset from the corner of the outlet and extends from the center direction of the outlet panel to the corner of the outlet. The pivot shaft of the guide vane is pivotally connected to the link in parallel with the longitudinal direction of the guide vane.

Here, the fact that the so-called “outer frame and inner frame enclose a polygonal air outlet” means that the outer frame and the inner frame are substantially polygonal, in which all parts capable of blowing out air are combined. It refers to having formed one. Moreover, the so-called "corner of the outlet" refers to the corner of the polygon which united all the parts which can blow off the air formed between the outer frame and the inner frame.

According to the blow-out panel of the above-mentioned configuration, for example, an air-conditioning indoor unit including an indoor unit main body provided with an axial flow fan is used by using a polygonal outlet surrounded by the outer frame and the inner frame. In this case, it is possible to approach the realization of blowing all around 360 °. And since the link to which the guide vanes are attached extends from the center direction of the blowout panel to the corner of the outlet, for example, an air conditioning indoor unit including an indoor unit main body provided with an axial flow fan is used In this case, the air flow blown out from the axial flow fan or the like easily flows along the link to the corner of the blowout port, and the blowout by the blowout port approaches uniform.

Further, according to the blowout panel of the above configuration, the connection structure of the guide vanes and the link is simplified, so that interference with the link of the guide vanes at the time of rotation can be avoided, and the guide vanes can be easily connected to the links. Become.

In this blowout panel, preferably, the link connects the outer frame and the inner frame.

According to the blowing panel of the said structure, the intensity | strength of the whole blowing panel becomes strong, and it is not necessary to increase another connection member. Moreover, compared with the case where other connecting members are increased, the obstruction to the air flow at the outlet by the other connecting members is reduced, and not only the structure becomes simple, but it becomes possible to increase the blowing panel. .

In this blowout panel, preferably, the link is provided in the vicinity of the corner bisector of the corner of the outlet.

According to the blowout panel of the above configuration, for example, when using an air conditioning indoor unit including the indoor unit main body provided with the axial flow fan, the air flow blown out from the axial flow fan or the like is the outlet along the link. It becomes easy to flow to the corner, and the blowout by the blowout approaches uniform.

In this blowout panel, preferably, the guide vane includes an elongated vane body, and a fixing piece perpendicular to the vane body and to which one end of the pivot shaft is connected. The link has a projecting piece protruding in a direction intersecting with the longitudinal direction of the link, and the other end of the pivot shaft is pivotally connected to the projecting piece.

According to the blow-out panel of the above-mentioned configuration, the pivot connection between the guide vanes and the link can be realized by a simple structure.

In the blowout panel, the link may include the link body and the connection portion. The connection portion is located at the center of the blowout panel rather than the link main body, and connects the link main body and the inner frame. The protrusion is provided on the link body.

According to the blowout panel of the above configuration, the strength of the entire blowout panel can be increased, and it is not necessary to increase other connection members. Moreover, compared with the case where other connecting members are increased, the obstruction to the air flow at the outlet by the other connecting members is reduced, and not only the structure becomes simple, but it becomes possible to increase the blowing panel. . Since the connection structure of the guide vanes and the link is simplified, interference with the link when the guide vanes rotate can be avoided, and the guide vanes can be easily connected to the links.

In this blowout panel, the protrusion is a first portion extending along the thickness direction of the blowout panel from the link main body, and a second portion extending at an angle to the first portion and parallel to the fixing piece A part may be provided. The other end of the pivot is pivotally connected to the second part.

According to the blowout panel of the above configuration, the first portion of the projection extends from the link body along the thickness direction of the blowout panel, so, for example, an air conditioning chamber including the indoor unit main body provided with the axial flow fan When using a machine or the like, the first portion of the projecting piece and the link can jointly guide the air flow generated from the axial flow fan or the like to the corner of the blowout panel. And since the 2nd part of a projection piece is parallel to a fixed piece, not only structure of a rotation axis becomes simple, but it becomes easy to assemble and an assembled structure is compact, and during rotation It is also possible to reduce the wear and tear of the pivot shaft.

In the blowout panel, the projection may be closer to the corner of the outlet than the fixing piece.

According to the blowing panel of the said structure, obstruction to the air flow in the corner | angular part of the blower outlet from the fixing piece and the end of a rotational axis can be reduced.

In the blowout panel, preferably, the link includes a first link and a second link provided on one side of the outlet. When viewed from the inner surface side to the outer surface side of the blowout panel, the second link is located downstream of the first link in the clockwise direction about the center of the blowout panel. The guide vane is provided with a first pivot and a second pivot pivotally connected to each of the first link and the second link.

Here, the so-called "outer surface of the blowout panel" refers to the surface facing the user when the blowout panel is attached to a room or the like, and the "inner surface of the blowout panel" is the opposite of "the outer surface of the blowout panel". Point to the side surface.

According to the blowout panel of the above configuration, the strength of the entire blowout panel can be increased, the assembly strength of the guide vanes can be improved, and the stability can be further stabilized during the inversion of the guide vanes.

In the blowout panel, an intermediate link may be further provided, and the guide vane may be provided with an intermediate pivot shaft pivotally connected to the intermediate link. When viewed from the thickness direction of the blowout panel, the intermediate link is located at the middle of the blowout port and perpendicular to the guide vanes. The intermediate link is attached with a stepping motor that drives the rotation of the guide vanes.

According to the blowing panel of the said structure, the force which a guide blade receives can be closely approached uniformly. This improves the stability and simplifies the drive structure. Further, by providing the stepping motor at the position of the outer frame of the blowout port, it is also advantageous to miniaturize the blowout panel.

In the blowout panel, preferably, the link comprises a link body and a connection. The connection portion is located at the center of the blowout panel rather than the link main body, and connects the link main body and the inner frame. The connection portion and the link body each have a first surface and a second surface. When viewed from the inner surface side to the outer surface side of the blowout panel, the first surface is located on the downstream side of the second surface in the clockwise direction about the center of the blowout panel. The second surface of the connection together with the second surface of the link body forms an inward concave shape.

According to the blowout panel of the above configuration, not only can the strength of the entire link can be ensured, but also the volume of the link can be reduced. For example, in the case of using an air conditioning indoor unit including an indoor unit main body provided with an axial fan, the obstruction to the air flow generated from the axial fan or the like from the connection of the link can be reduced. The blowout due to becomes close to uniform. Then, using the second surface of the link connection portion, it becomes easy to guide the air flow generated by the axial fan and the like to the corner of the outlet through the second surface of the link main body. Also from the corner of the outlet, the air flow comes to be blown out, and furthermore, the blowout panel achieves 360 ° blowing.

In the blowout panel, preferably, the link includes a first link and a second link provided on one side of the outlet. When viewed from the inner surface side to the outer surface side of the blowout panel, the second link is located downstream of the first link in the clockwise direction about the center of the blowout panel. The first link and the second link on both sides of the same corner of the outlet are formed such that the link body of the first link is parallel to the link body of the second link.

According to the blowout panel of the above configuration, the entire structure of the blowout panel can be simplified, and obstruction to the air flow at the corner of the blowout from the link main body of the link can be reduced. Approaches uniform.

In the blowout panel, preferably, a central member provided with a wind guide piece is installed at the center of the inner frame.

According to the blow-out panel of the above configuration, for example, when using an air-conditioning indoor unit including an indoor unit main body provided with an axial flow fan, the air guide piece is used to guide the air flow generated by the axial flow fan or the like. Thereby, the air flow is prevented from being directly blown downward, and the air flow guided by the air guide piece flows along the link to the corner of the blowout port, and the blowout by the blowout port approaches uniform. .

In the blowout panel, the link may be configured to include the link body and the connection portion. The connection portion is located at the center of the blowout panel rather than the link main body, and connects the link main body and the inner frame.

The embodiment will be described below with reference to FIGS. 1 to 10, taking an air conditioning indoor unit provided with an indoor unit main body and a blowout panel as an example, according to an actual mounting state.

Here, for convenience of explanation, three directions orthogonal to one another are set as the X direction, the Y direction, and the Z direction, and among them, the X direction and the Y direction are the directions in the horizontal plane in the actual mounting state of the air conditioning indoor unit , And the Z direction corresponds to the vertical direction in the actual mounting state of the air conditioning indoor unit. The Y1 direction side, the Y2 direction side, the X1 direction side, the X2 direction side, the Z1 direction side, and the Z2 direction side are the front side, the rear side, the left side, the right side, and the lower side in the actual mounting state of the air conditioning indoor unit, respectively. And correspond to the upper side.

As shown in FIG. 1, the air conditioning indoor unit 1 includes an indoor unit main body 10 in which an axial fan 30 is provided, and a blowout panel 20 connected to the indoor unit main body 10 (in the illustrated example, The blowout panel 20 is provided below the indoor unit body 10).

Here, the indoor unit body 10 has a substantially rectangular parallelepiped shape overall, and has an upper surface, a bottom surface, and four side surfaces. An intake port JF is provided on each side surface, and a filter component 40 is provided at each intake port JP. As shown in FIG. 1, a heat exchanger 50 is further provided inside the indoor unit body 10. The heat exchanger 50 is provided inside the inlet JF and surrounded by the filter component 40. In addition, an axial flow fan 30 is provided inside the heat exchanger 50. The axial fan 30 is provided so that the rotation axis overlaps the central axis L of the blowout panel 20 (that is, an axis extending through the center of the blowout panel 20 along the thickness direction of the blowout panel 20) There is.

Further, as shown in FIGS. 1 and 2, the blowout panel 20 has an outer frame 21 and an inner frame 22. A polygonal air outlet CF is surrounded by the outer frame 21 and the inner frame 22. A guide vane 23 is provided in the blowout port CF. The blowout panel 20 is provided with a link 24. The link 24 is offset from the corner of the outlet CF (that is, the link 24 does not pass through the top of the corner of the outlet CF) and extends from the center direction of the outlet panel 20 to the corner of the outlet CF ing. A guide vane 23 is rotatably attached to the link 24.

Here, as shown in FIG. 1 and FIG. 2, when viewed from the inner surface side to the outer surface side of the blowout panel 20, specifically, from the one side (Z2 direction side) of the indoor unit main body 10 of the blowout panel 20. When viewed from one side (Z1 direction side) away from the indoor unit body 10, the link 24 has a first surface (downstream side in the clockwise direction in FIG. 2) and a second surface (in FIG. 2) (Upstream side in the clockwise direction). The air flow generated by the axial fan and the like sequentially flows through the second surface and the first surface. That is, the second surface is the wind surface, and the first surface is the wind surface.

Here, as shown in FIG. 2, the blowout panel 20 has a substantially rectangular shape, and has a rectangular outer frame 21 and a rectangular inner frame 22. A rectangular air outlet CF is surrounded by the outer frame 21 and the inner frame 22. One set of guide vanes 23 is provided on each side of the blower outlet CF (each side constitutes an auxiliary blower outlet). As shown in FIGS. 2 and 3, each set of guide vanes 23 is combined by three parallel guide vanes. The lengths of the three parallel guide vanes are provided to increase along the direction from the inner frame 22 to the outer frame 21 of the blowout panel 20. When the guide vanes 23 rotate to open the air outlet CF, the air flow at both ends of the guide vanes 23 gradually diffuses downward along the ends of the plurality of guide vanes 23 and is parallel It is not something that is blown out. Therefore, the air flow having a relatively low flow velocity at both ends of the guide vanes 23 is not attached to the ceiling. Thereby, it is avoided that contaminants such as dust caught in the air flow are attached to the ceiling. And as a whole, since most of the air flow is still guided by the guide vanes 23, it is still possible to keep the air flow evenly distributed.

Further, as shown in FIG. 2, the link 24 connects the outer frame 21 and the inner frame 22 and is provided in the vicinity of a corner bisector of the corner of the outlet CF (in the illustrated example, , Links 24 are parallel to the angular bisector of the corners of the outlet CF). And the link 24 is provided with the 1st link 24A and the 2nd link 24B which were provided in one side of the blower outlet. When viewed along the Z direction (specifically, viewed from the viewpoint of FIG. 2), the vertical line CX passing through the center of the blowout panel 20 on one side of the blowout port CF is the first link 24A. , Located on the downstream side in the clockwise direction around the center of the blowout panel. The second link 24B is located downstream of the vertical line CX in the clockwise direction about the center of the blowout panel. Therefore, the air flow generated by the axial fan and the like can be guided to the two corners of the outlet CF by using the first link 24A and the second link 24B, respectively, and the two corners of the outlet CF Both of the airflows in the section approach a uniformly distributed state.

Further, as shown in FIGS. 1 to 3, a central member 26 is provided below the axial flow fan 30 and above the blow-out panel 20 (in the illustrated example, a protrusion toward the axial flow fan 30) The shape is not limited thereto, and the shape may be changed as appropriate). The central member 26 is provided with a wind guide piece 261. The end point of the suction end of the air guide piece 261 is located at the extension of the link body of the link 24.

Also, as shown in FIG. 2, when viewed along the Z direction, the air guide pieces 261 are arc-shaped. The air guide piece 261 includes a first air guide piece 261A and a second air guide piece 261B. When viewed along the Z direction (specifically, viewed from the viewpoint of FIG. 2), the first wind guide piece 261A is a portion of the second wind guide piece 261B around the center of the blowout panel. It is located on the upstream side in the clockwise direction.

Here, as shown in FIG. 2, one first link 24A and one second link 24B are provided on one side of the outlet CF. And, one first air guide piece 261A and one second air guide piece 261B are provided.

As shown in FIGS. 2 and 4, the first link 24A includes a link main body 241A in which the guide vanes 23 are rotatably provided, and a connection portion 242A. The connection portion 242A is located in the center direction of the blowout panel 20 relative to the link main body 241A, and connects the link main body 241A and the inner frame 22. Further, when viewed along the Z direction, the second surface 2421A of the connection portion 242A forms a concave shape inward together with the second surface 2411A of the link main body 241A. Here, as shown in FIG. 6 and FIG. 8, the connection portion 242A connects the first portion 2423A substantially extending along the extension direction of the link main body 241A and the first portion 2423A to the inner frame 22. And the second portion 2424A. Among them, the first part and the second part both have a guide surface that exerts a guiding action. Specifically, the end faces of the first portion 2423A and the second portion 2424A approaching in the center direction of the blowout panel are both arc-shaped guide surfaces. Further, the end face of the second portion 2424A remote from the center direction of the outlet panel is a chamfered surface extending toward the corner of the outlet CF (that is, the closer the corner of the outlet CF is, The upwind face and the downwind face are closer). The chamfered surface guides the air flow generated by the axial flow fan or the like to the corner of the outlet CF.

As shown in FIGS. 2 and 5, the second link 24B includes a link main body 241B in which the guide vanes 23 are rotatably provided, and a connection portion 242B. The connection portion 242B is located closer to the center of the blowout panel 20 than the link main body 241B, and connects the link main body 241B and the inner frame 22. Further, when viewed along the Z direction, the second surface 2421B of the connection portion 242B forms a concave shape inward together with the second surface 2411B of the link main body 241B. Similarly, as shown in FIG. 8, the connecting portion 242 B connects the first portion 2423 B substantially extending along the extending direction of the link main body 241 B, and the first portion 2423 B to the inner frame 22. And two portions 2424B. Among them, the first part and the second part both have a guide surface that exerts a guiding action. Specifically, the end faces of the first portion 2423B and the second portion 2424B approaching in the center direction of the blowout panel are both arc-shaped guide surfaces. The end face of the second portion 2424B remote from the center direction of the outlet panel is a chamfered surface extending toward the corner of the outlet CF. The chamfered surface guides the air flow generated by the axial flow fan or the like to the corner of the outlet CF.

Here, as shown in FIG. 4, in the first link 24A, the wind surface, which is the second surface 2411A of the link main body 241A, and the wind surface, which is the first surface 2412A, are substantially flat. The second surface 2421A of the connection portion 242A and the first surface 2422A are substantially flat. The second surface 2411A of the link main body 241A intersects with the second surface 2421A of the connection portion 242A. The first surface 2412A of the link main body 241A is substantially flush with the first surface 2422A of the connection portion 242A, or forms an obtuse angle larger than the second surface. For this reason, the air flow guided from the air guide piece can be guided to the link main body 2412A along the first surface 2422A of the connection portion 242A, and can be further guided to the corner of the outlet CF. Similarly, as shown in FIG. 5, in the second link 24B, the wind surface that is the second surface 2411B of the link main body 241B and the wind surface that is the first surface 2412B are substantially flat. The second surface 2421B of the connection portion 242B and the first surface 2422B are substantially flat. The second surface 2411B of the link main body 241B intersects with the second surface 2421B of the connection portion 242B. The first surface 2412B of the link main body 241B forms an obtuse angle that is substantially flush with the first surface 2422B of the connection portion 242B or larger than the wind surface. For this reason, the air flow guided from the air guide piece can be guided to the link main body 2412B along the first surface 2422B of the connection portion 242B, and can be further guided to the corner of the outlet CF.

Moreover, as shown in FIGS. 4 and 5, in the first link 24A, the second surface 2421A of the connection portion 242A makes an obtuse angle with the second surface 2411A of the link main body 241A. In the second link 24B, the second surface 2421B of the connection portion 242B makes an obtuse angle with the second surface 2411B of the link main body 241B. Therefore, when the air flow generated by the axial flow fan or the like flows to the link

main bodies

241A and 241B along the

connection portions

242A and 242B, the direction of the air flow gradually changes. As a result, turbulent flow is less likely to be formed at the connection portions between the

second surfaces

2421A and 2421B of the

connection portions

242A and 242B and the

second surfaces

2411A and 2411B of the link

main bodies

241A and 241B.

Further, as shown in FIGS. 6 to 9, in the first link 24A, the pivot shaft 29 of the guide vanes 23 is pivotally connected to the link main body 241A in a substantially horizontal state. Specifically, the guide vanes 23 include an elongated vane main body 231 and a fixing piece 232. The fixed piece 232 is perpendicular to the blade main body 231, and one end of the rotating shaft 29 is connected. The first link 24A has a projecting piece 243 that protrudes in a direction intersecting the longitudinal direction of the first link 24A. The projecting piece 243 constitutes a support portion for supporting the pivot shaft 29. The other end of the pivot shaft 29 is pivotally connected to the projecting piece 243. In the illustrated example, the protruding piece 243 is provided on the link main body 241A, and is closer to the corner of the outlet CF than the fixed piece 232. Since the boundary between the connection portion 242A and the link main body 241A is located between the inner frame 22 and the pivot shaft 29, the guide vanes 23 are stably pivoted. The projecting piece 243 includes a first portion 2431 and a second portion 2432 extending from the link main body 241A along the thickness direction of the blowout panel 20. The second portion 2432 extends at an angle to the first portion 2431 and is parallel to the fixing piece 232. The other end of the pivot shaft 29 is pivotally connected to the second portion 2432.

Similarly, as shown in FIGS. 6 to 9, in the second link 24B, the pivot shaft of the guide vanes 23 is pivotally connected to the link main body 241B in a substantially horizontal state. Specifically, the guide vanes 23 include a vane main body 231 having a long shape and a fixing piece 232. The fixed piece 232 is perpendicular to the blade main body 231, and one end of the pivot shaft 29 is connected. The second link 24B has a projecting piece 243 which protrudes in a direction intersecting with the longitudinal direction of the second link 24B. The projecting piece 243 constitutes a support portion for supporting the pivot shaft 29. The other end of the pivot shaft 29 is pivotally connected to the projecting piece 243. In the illustrated example, the protruding piece 243 is provided on the link main body 241B, and is closer to the corner of the outlet CF than the fixed piece 232. Since the boundary between the connection portion 242B and the link main body 241B is located between the inner frame 22 and the pivot shaft 29, the guide vanes 23 rotate stably. The projecting piece 243 includes a first portion 2431 and a second portion 2432 extending from the link main body 241B along the thickness direction of the blowout panel 20. The second portion 2432 extends at an angle to the first portion 2431 and is parallel to the fixing piece 232. The other end of the pivot shaft 29 is pivotally connected to the second portion 2432.

Moreover, as shown in FIG. 7 and FIG. 9, a buffer ring 291 is integrally formed on the rotating shaft 29. The buffer ring 291 is located between the fixed piece 232 and the projecting piece 243 when the guide vanes 23 are attached. The buffer ring 291 prevents clogging of the pivoting rotation of the guide vanes or acceleration of wear of the fixed piece or the like due to the friction between the fixed piece 232 and the protruding piece 243. Here, since the other end of the pivot shaft 29 is hollow and divided into four pieces, it is possible to form a space of elastic deformation, which is convenient for attaching and detaching the guide vanes 23. One end of the pivot shaft 29 may be integrally formed with the fixed piece 232 or may be fixedly adhered to the fixed piece 232.

Further, as shown in FIGS. 2, 6 and 7, the first link 24A and the second link 24B are provided at both ends in the longitudinal direction of the same guide vane 23 via the pivot shaft 29, respectively. The provided projecting piece 243 is pivotally connected. For this reason, the guide vanes 23 rotate stably. The protruding pieces 243 provided on the first link 24A and the second link 24B are provided closer to the corner of the outlet CF than the fixing pieces 232 provided on both ends of the guide vanes. ing. That is, the fixing pieces 232 at both ends of the guide vanes 23 are respectively provided on different sides of the first link 24A and the second link 24B. For this reason, compared with the case where the fixed piece 232 is provided on the same side of the first link 24A and the second link 24B, the pivot shaft 29 is prevented from dropping off the projecting piece 243.
