Description

The present invention relates to a wall-mounted air conditioner, and more specifically, includes a movable panel that can be slid up and down to relieve the visual pressure caused by protruding from a wall surface, and to slide the movable panel. Thus, the present invention relates to a structure in which a guide continuous to the air outlet is configured to improve the air blowing performance, and air near the ceiling surface of the air-conditioned room can be efficiently sucked from the air inlet.

As shown in FIG. 1 and FIG. 8 of Patent Document 1, the conventional wall-hanging air conditioner is capable of reaching warm air or cold air all over the air-conditioned room. The main body has a suction port on the front and upper surfaces, a blower on the lower surface, and a heat exchanger and a blower fan in the air passage connecting the suction port and the blower. The wall is installed in the vicinity of the ceiling surface in the upper part of the wall surface (see, for example, Patent Document 1).

When the air conditioner having the above configuration is installed on a wall in the vicinity of the ceiling surface B, which is the upper part of the wall surface A of the air-conditioned room, as shown in FIGS. 5 (A) and 5 (B) Visual compression due to the entire air conditioner projecting forward from the wall surface A because the cross of the suction port 2 and the blower outlet 4 of the portion (and the upper surface portion 1) always appear in the appearance. There was a feeling.

Further, when the suction port 2 of the upper surface portion 1 is installed near the ceiling surface B, the space between the upper surface portion 1 and the ceiling surface B becomes narrow as shown in FIG. Thus, there is a problem that it is difficult to efficiently suck indoor air from the suction port 2 of the upper surface portion 1.

With the above configuration, when the operation is stopped, the air outlet 4 is closed by the up and down wind direction plates 10 and 11 as shown in FIG. 6A. For example, when the air is blown out horizontally during the cooling operation, the air outlet 4 is shown in FIG. As described above, since the up-and-down wind direction plates 10 and 11 are rotated to the horizontal position, a part of the blown cold air exchanged by the heat exchanger 5 and sent from the blow-out port 4 by the blower fan 6 is There is a risk that the heat exchange efficiency may be reduced due to a short circuit being sucked in from the suction port 2 of the part, and when the vertical blowout by heating operation is performed, the vertical wind direction plates 10 and 11 are vertical as shown in FIG. Since it is rotated to the position, the warm air blown out by the heat exchanger 5 and delivered from the blower outlet 4 by the blower fan 6 is rapidly deflected downward by the vertical wind direction plates 10 and 11. Is therefore, blowing efficiency in the relevant section had a problem that deteriorates.

Therefore, while improving the design, the opening / closing body opens and closes the inlet of the front part of the main body according to the amount of intake air. For example, a large amount of air is sucked from the inlets provided at the upper front and upper parts of the main body In some cases, the opening / closing body is driven by a drive motor, and the upper portion of the opening / closing body and the movable panel are separated from each other so that the room air can be sucked from the suction port on the upper front surface (see, for example, Patent Document 2). ).

However, when the upper part of the main body is close to the ceiling surface, it is basically the same as in Patent Document 1, and is sufficient for guiding a large amount of intake air between the upper part of the main body and the ceiling surface. It was difficult to secure a flow passage, and the air conditioner as a whole protruded forward from the wall surface, causing a sense of visual pressure, making it difficult to harmonize with the interior of the air-conditioned room. .

Note that the air outlet for blowing conditioned air into the air-conditioned room is the same as in the case of Patent Document 1, and has a configuration that is conscious of blowing in both the horizontal and vertical directions, and is provided in the air outlet. Since the wind direction is controlled only by the vertical wind direction plate, the wind direction adjustment range is narrowed.For example, the wind direction can be effectively deflected to sufficiently blow the air in the horizontal direction and the air in the vertical direction. Had the problem of not.

Moreover, as shown in the design literature 1, what covered the air conditioner main body with a curved movable panel is recognized, and as shown in the design literature 2, the air conditioner main body is covered with a movable panel that slides up and down. As shown in Design Document 3, a movable panel that rotates up and down covers the air conditioner main body. However, in any case, the movable panel continues to the outlet. However, it was not designed to increase the air blowing efficiency by configuring a part of the blowout passage (see, for example, Patent Document 3 to Patent Document 5).

Therefore, it is possible to efficiently suck in indoor air from the suction port, eliminate the possibility of short circuit, and cover it with a movable panel so that the suction port pier and outlet do not always appear on the exterior, and feel visual pressure For example, the movable panel constitutes a part of a guide that continues to the air outlet to increase the air blowing efficiency, effectively deflect the air direction and blow the air far away in the horizontal direction. It has been desired to allow sufficient ventilation in the vertical direction.

In view of the above problems, the present invention is provided with a movable panel that can be slid up and down to relieve the visual pressure caused by protruding from the wall surface, and by sliding the movable panel, a guide that is continuous with the outlet. It is an object of the present invention to provide a wall-mounted air conditioner that can improve the ventilation performance and efficiently suck air in the vicinity of the ceiling surface of the air-conditioned room from the suction port.

In order to solve the above-mentioned problems, the present invention is provided with a suction port in an upper surface part whose front end is inclined downward, and has a blower port hung in front of the lower surface part and below the front surface part that is narrower than the depth of the upper surface part. A wind direction plate is provided on the side, and a main body portion including a heat exchanger and a blower fan in an air passage connecting the suction port and the air outlet, and a front end of the upper surface portion and a front end of the lower surface portion of the main body portion are connected. A movable panel is attached to the inclined front part, and at the time of horizontal blowing, the movable panel is not separated from the main body part but is movable upward by sliding forward and continuing to the outlet. The front side of the panel constitutes a guide for guiding the blown air, and when the vertical blowout, the wind direction plate rotates downward and the movable panel is downward and slides backward, and the back side of the movable panel guides the blown air Make up .

Furthermore, the said movable panel is formed in concave shape with respect to the front by curving up and down.

According to the present invention, since the movable panel that can slide up and down is provided, it is easy to harmonize with the interior of the air-conditioned room by reducing the visual feeling of pressure, and suck in the air near the ceiling surface of the air-conditioned room By efficiently sucking in from the mouth and configuring the guide that continues to the outlet by sliding the movable panel, it effectively blows out the horizontal cold air or the vertical warm air blown out from the outlet. As a result, the wind direction adjustment range can be expanded without difficulty and air can be blown far away.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail as examples based on the attached drawings.
FIG. 1 is an explanatory view showing a basic configuration of an air conditioner according to the present invention, in which (A) is a front view, (B) is a side view, (C) is a side sectional view, and (D) is a perspective view. 2 is a side view showing an example of a movable panel of an air conditioner according to the present invention, (A) shows a first example, (B) shows a second example, and FIG. FIG. 4 is a side sectional view showing an example of an up-and-down wind direction plate, where (A) shows a state when operation is stopped, (B) shows a state when horizontal blowing, (C) shows a state when vertical blowing, and FIG. Is a side sectional view showing another example of the sliding position of the movable panel and the up-and-down wind direction plate of the outlet, where (A) shows the state at the time of operation stop, (B) shows the state at the time of horizontal blowing, and (C) shows The state at the time of vertical blowing is shown respectively.

As shown in FIGS. 1 (A) to 1 (C), the main body 100 of the air conditioner according to the present invention protrudes forward in a side view and is inclined downward toward the front end 1a. The lower surface portion 3 narrower than the depth of the upper surface portion 1 and the inclined front surface portion 7 connecting the front end 1a of the upper surface portion 1 and the front end 3a of the lower surface portion 3 form a halved sector shape. Then, the movable panel 8 is slidably mounted on the front surface portion 7 and is installed on the wall surface A near the ceiling surface B of the air-conditioned room.
In addition, the upper surface portion 1 is provided with a suction port 2, and is provided with a blower outlet 4 hung below the front surface portion 7 and in front of the lower surface portion 3. Fan 6 is provided.

Even if the upper surface portion 1 is installed in the vicinity of the ceiling surface B, the upper surface portion 1 is inclined downwardly toward the front end 1a, so that the upper surface portion 1 is spaced from the suction port 2 with the ceiling surface B. A gap (ventilation path) for sucking room air can be secured.

As shown in FIG. 2A as a first example, the movable panel 8 has an upper end portion 8a protruding above the suction port 2 and a lower end portion 8b protruding below the outlet 4 when operation is stopped. It is configured.

As a result, when the air conditioner main body according to the present invention is looked up from the air-conditioned room, as shown in FIG. 1 (D), the main body 100 can be shielded from being seen by the movable panel 8 when the operation is stopped. In addition, since the boundary portion C between the wall surface A and the ceiling surface B can also be shielded, the visual pressure feeling that the air conditioner main body protrudes from the wall surface A can be relieved, so It has a unique effect of being easy to harmonize with the interior of the room.

Moreover, as shown in FIG. 2B as a second example, the movable panel 8 may be configured to be formed in a concave shape with respect to the front by being bent in the vertical direction. This makes it possible to more effectively relieve the visual pressure of the air conditioner body, and it also makes it easier to respond to user preferences and interiors of air-conditioned rooms. It will be possible to provide a high-quality air conditioner with

As shown in FIGS. 3 (A) to 3 (C) as the first embodiment, the movable panel 8 is connected to a link motor or a linkage gear that slides the movable panel 8 up and down and back and forth. The driving device 9 is linked, and the driving device 9 shields the air outlet 4 according to the operation state such as when the operation is stopped, when the air is blown horizontally, when the air is blown vertically, or when the air is blown vertically. It is configured such that it can be stopped at a position or slid up and down and back and forth.

That is, when the operation is stopped, as shown in FIG. 3A, the movable panel 8 has an upper end portion 8 a protruding above the upper surface portion 1 and a lower end portion 8 b protruding below the lower surface portion 3. The air outlet 4 stops at a position, and the air outlet 4 is closed by a first up and down air direction plate 10 and a second up and down air direction plate 11 which are rotatably provided at the air outlet 4 and deflect the air direction in the up and down direction. It has become so. The second up-and-down wind direction plate 11 is superposed on a part of the movable panel 8.

Further, at the time of horizontal blowing by cooling operation, as shown in FIG. 3B, the driving device 9 causes the movable panel 8 to slide upward and forward as indicated by an arrow c, and the lower end portion 8b is The air outlet 4 is stopped at a position where the air outlet 4 is opened, and the air outlet 4 is closed at the lower side by the first vertical air direction plate 10 while the front side has the second vertical air direction plate 11 around the support shaft 11a. It is opened by rotating to a horizontal position.

As a result, as shown by the arrow a, the suction air sucked from the suction port 2 is heated by the heat exchanger 5 by the gap (ventilation path) secured between the ceiling surface B and the upper surface portion 1. After the replacement, the blower fan 6 can blow cool air from the opened outlet 4 into the air-conditioned room as indicated by an arrow b.

At this time, since the upper end portion 8a of the movable panel 8 is upward and protrudes greatly forward, a so-called short circuit phenomenon in which the blown cold air circulates into the suction port 2 does not occur.

Since the first up-and-down wind direction plate 10 constitutes a part (lower part) of the air outlet 4, the air outlet 4 can be formed as an air passage extending in the horizontal direction, and the air blowing efficiency can be improved. In addition, a part of the blown cold air deflected in the horizontal direction by the first vertical airflow direction plate 10 is configured as a guide in which the front side 8c of the movable panel 8 that is slid is connected to the blowout port 4. And since it comes to blow off along the movable panel 8 as this guide, blowing efficiency can be made to reach to a distant place by raising blowing efficiency, without causing what is called cold fall.

At the time of vertical blowing by heating operation, as shown in FIG. 3C, the movable panel 8 is slid downward and rearward as indicated by an arrow d by the driving device 9, and the lower end portion 8b is The air outlet 4 stops at a position where the front of the air outlet 4 is closed, and the air outlet 4 is opened by rotating the first vertical airflow direction plate 10 about the support shaft 10a to the vertical position. It has become.

As a result, as shown by the arrow a, the air exchanged by the heat exchanger 5 is exchanged between the suction air sucked from the suction port 2 by a gap (ventilation path) secured between the ceiling surface B and the upper surface 1. After that, the blower fan 6 can blow out warm air from the opened outlet 4 to the lower side of the air-conditioned room as indicated by an arrow b ′.

At that time, since the movable panel 8 is downward and protrudes largely rearward, the back surface side 8d of the movable panel 8 and the first up-and-down airflow direction plate 10 are continuously perpendicular to the outlet 4. Since the blowing path extending in the direction can be configured, the blowing efficiency can be increased, and the blowing warm air is efficiently guided in the vertical direction.

In addition, since the movable panel 8 is formed in a concave shape by being bent in the vertical direction, for example, at the time of horizontal blowing by cooling operation, the blown cold air at the blowout outlet is blown out without resistance, and The blown cold air along the upper end portion 8a is effectively deflected toward the far side in the horizontal direction without going toward the ceiling surface B.

Further, when the vertical blowout is performed by heating operation, the blowout passage continuing to the blowout port 4 is formed like a nozzle between the back side 8d of the movable panel 8 and the first vertical airflow direction plate 10 as shown in FIG. Therefore, it is possible to realize effective foot heating.

Next, as Example 2, a configuration when the position of the support shaft 11a of the second up-and-down wind direction plate 11 is changed will be described.

In addition, about the combination of the said movable panel 8, the said 1st up-and-down wind direction board 10, and the said 2nd up-and-down wind direction board 11 at the time of an operation stop and a vertical blowing, based on FIG. 3 (A) and FIG. 3 (C). Since it is the same as the case of the first embodiment described above, FIG. 3 (A) is replaced with FIG. 4 (A) and FIG. 3 (C) is replaced with FIG. 4 (C). I will omit the explanation.

As shown in FIG. 4B, at the time of horizontal blowing in the cooling operation, the movable panel 8 slides upward and forward as indicated by an arrow c by the driving device 9, and the lower end portion 8b is moved to the blowing portion. While stopping at the position where the outlet 4 is opened, the blower outlet 4 is closed at the lower side by the first up-and-down airflow direction plate 10, while the front is at the second up-and-down centering on the support shaft 11a provided at the lower end position. The wind direction plate 11 is opened by rotating to a horizontal position, and the first vertical wind direction plate 10 and the second vertical wind direction plate 11 constitute a part (lower part) of the outlet 4. In addition to the configuration, it is configured to be able to form an outlet passage that is continuous with the outlet 4.

As a result, the air sucked from the suction port 2 is heated by the heat exchanger 5 through a gap (ventilation path) secured between the ceiling surface B and the upper surface 1 as indicated by an arrow a. After the replacement, the blower fan 6 can blow cool air from the opened outlet 4 into the air-conditioned room as indicated by an arrow b.

At that time, since the upper end 8a of the movable panel 8 is upward and protrudes forward and the front side 8c of the movable panel 8 constitutes a guide for guiding the blown cold air, the same as in the case of the first embodiment. In addition, there is no occurrence of a so-called short circuit phenomenon in which the blown cold air flows into the suction port 2.

The first up-and-down air direction plate 10 and the second up-and-down air direction plate 11 constitute a part (lower part) of the air outlet 4, thereby providing a longer air passage extending in the horizontal direction than in the case of the first embodiment. As a result, the air blowing efficiency can be further improved, and the front side 8c of the movable panel 8 that has been slid is configured as a guide that continues to the air outlet 4. Since the air is blown out along the movable panel 8 as the guide, the blown cold air can be delivered to a far place by increasing the blowing efficiency without causing the so-called cold air drop as in the case of the first embodiment. .

As described above, in the air conditioner according to the present invention, even if the upper surface portion 1 is wall-mounted in the state of being close to the ceiling surface B, the upper surface portion 1 is inclined downward toward the front end 1a. As a result, a gap (ventilation path) for sucking room air from the suction port 2 can be secured between the ceiling surface B and the movable panel 8 can be slid to slide the blower outlet. By configuring the guide continuous with 4, it becomes possible to effectively blow out the horizontal cold air or the vertical warm air blown out from the air outlet 4, so that the wind direction adjustment range can be easily expanded. As a result, it is possible to sufficiently blow air far away.
