Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a vertical wind direction device and an air conditioner using the same.
[0002]
[Prior art]
As a conventional vertical direction device for an air conditioner, there is one as disclosed in Japanese Patent Application Laid-Open No. 10-61965, and a perspective view of the device and a cross-sectional view of a blow-out air path are shown in FIGS.
In these figures, 1 is an air-conditioning indoor unit, 1a is a cabinet of the air-conditioning indoor unit 1, 1b is provided in the cabinet 1a, and an air outlet for blowing cool air or warm air, and 2 is an air passage for the air outlet 1b. An upper flap, which is arranged and adjusts a blowing direction of cold air or warm air, etc., 2a is an upper flap rotating plate of the upper flap 2, 2b is an upper flap rotating shaft attached to the upper flap rotating plate, and 3 is an outlet. The lower flap, which is arranged in the air passage 1b and adjusts the blowing direction of cold air or warm air, is a lower flap rotating plate of the lower flap 3, and 3b is a lower flap rotating plate attached to the lower flap rotating plate 3a. The driving shaft 4 is connected to the lower flap rotating shaft 3a and the upper flap rotating shaft 2a via a link arm 5 to drive the upper flap 2 and the lower flap. Built in the indoor unit 1, a blower for blowing cold air or warm air or the like into the outlet air passage 1b.
[0003]
The upper flap 2 and the lower flap 3 are each composed of a single plate as shown in FIG. 11, and the single plate is used to make the wind direction horizontal or vertical. When a plate structure taking into account the airflow resistance is used, the airflow resistance in the vertical direction is increased. Conversely, when a plate structure is used in consideration of the airflow resistance in the vertical direction, the airflow resistance in the horizontal direction is increased.
[0004]
Next, the operation of this configuration will be described.
First, as shown in FIG. 9, air such as cool air or warm air blown from the blower 6 passes through the blowing air path 1 b and blows out into a room or the like while being guided by the upper flap 2 and the lower flap 3 in this air path. When the drive motor 6 is driven to rotate its shaft, and the rotation is transmitted to the upper flap rotation shaft 2a and the lower flap rotation shaft 3a via the link arm 5, the upper flap is rotated. The lower flap 2 and the lower flap 3 rotate to be substantially horizontal or substantially vertical.
[0005]
Therefore, when the air becomes substantially horizontal, the air from the air outlet path 1b is blown in a substantially horizontal direction, and when the air becomes substantially vertical, the air is blown in a substantially vertical direction.
However, in order to change the direction of the air blown out of the blow-out air passage 1b by a single wind direction plate in a certain direction, if the wind resistance in one direction is reduced as described above, Wind resistance increases, and the air flow decreases.
As described above, the conventional vertical wind direction device of an air conditioner drives the upper and lower flaps simultaneously by one drive device to change the wind direction in the horizontal or vertical direction, which is economical but increases resistance. , The air volume was reduced.
Further, when the shape of the upper and lower flaps is not the same, or when the inclination angle of the upper wall and the lower wall of the air path is different, the resistance is increased, and the air volume is reduced. In addition, the shape of the upper and lower flaps and the upper and lower structures of the air path must be regulated, resulting in a structure with a low degree of freedom in design.
[0007]
[Problems to be solved by the invention]
As described above, the conventional vertical wind direction device and the air conditioner using the same have a structure in which the upper and lower wind direction flaps are driven and changed at the same time, so that the blowing resistance increases and the air volume decreases. There was a problem of doing.
[0008]
Further, in order to prevent air path resistance and a decrease in air volume, the shape of the upper and lower flaps and the upper and lower structures of the air path structure must be regulated, and there is a problem that the degree of freedom in design is low.
[0009]
The present invention has been made in order to solve the above problems, and has a high degree of freedom in design with respect to upper and lower flaps and an air path structure, and uses a vertical wind direction device that prevents a decrease in air volume and uses the same. The purpose is to obtain an air conditioner.
[0010]
It is another object of the present invention to obtain a vertical wind direction device having good assembling workability and excellent detachability and an air conditioner using the same.
[0011]

The vertical direction of the airflow on the lower side of the road is gradually changed.
[0012]
Further, a lower drive device rotates the upper flap and the lower downstream flap via a lower link mechanism, and an upper drive device rotates the lower upstream flap via an upper link mechanism. Things.

BEST MODE FOR CARRYING OUT THE INVENTION
Embodiment 1 FIG.
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view of the blow-out air passage of the air conditioner, FIG. 2 is a diagram showing the relationship between the upper and lower flaps and the vertical drive device, FIG. 3 is a perspective view of the vertical wind direction device, and FIG. FIG. 5 is a cross-sectional view of the blow-out air path at the time of horizontal blowing, and FIG. 5 is a cross-sectional view of the blow-out air path at the time of downward blowing.
In these figures, reference numeral 1 denotes an indoor unit of an air conditioner, 1a denotes a cabinet of the air-conditioning indoor unit 1, 1b is provided in the cabinet 1a, and a blow air passage for blowing cool air or warm air, and 2 denotes a blow air passage. An upper flap 2a is provided at one end of the upper flap 2 and an upper flap 2b is provided at an upper end of the upper flap 2 and arranged above the air path 1b to adjust the direction of the air flow in the vertical direction of blowing out cold air or warm air. Reference numeral 2a denotes a rotating shaft that fixes the upper shaft 8a of the lower link mechanism 8, and 30 denotes a lower flap that is disposed below the outlet air passage 1b and that adjusts the wind direction in the vertical direction of the outlet such as cold air or warm air. The lower flap 30 is composed of a lower upstream flap 31 and a lower downstream flap 32, and these upstream and downstream flaps are arranged substantially in series (in a row) along the blowing air path 1b.
[0019]
A lower drive motor 7 is fixed to the cabinet 1a, rotates the upper flap 2 and the lower downstream flap 32 via the lower link mechanism 8, and 9 is fixed to the cabinet 1a and lowers via the upper link mechanism 10. An upper drive motor for rotating the upstream flap 31, and the shaft 9 a of the upper drive motor 9 is hollowly rotated by the lower downstream flap 32 connected to the lower link mechanism 8 that transmits the rotational force of the lower drive motor 7. The shaft 9a penetrates the shaft 32b, and the penetrated shaft 9a is rotatably supported by the turning shaft 31b of the turning plate 31a of the lower upstream flap 31 via the upper link mechanism 10.
[0020]
That is, the upper link mechanism 10 is connected to the distal end side of the shaft 9a, and the upper link mechanism 10 is fixed to the rotating plate 31a of the lower upstream flap 31 via the rotating shaft 31b. When the upper drive motor 9 is driven to rotate the shaft 9a, the lower upstream flap 31 rotates.
[0021]
The lower drive motor 7 has a shaft 7a connected to a lower link mechanism 8, and the lower link mechanism 8 includes an upper flap rotation shaft 2b fixed to the rotation plate 2a of the upper flap 2, and a lower downstream mechanism. The upper flap 2 and the lower downstream flap 32 are connected when the upper drive motor 7 is driven to rotate the shaft 7a because the upper flap 2 is connected to the hollow rotary shaft 32b fixed to the rotary plate 32a of the side flap 32. It will rotate.
[0022]
Next, the operation thus configured will be described.
First, when the power is turned on, the blower 6 rotates, and the air is blown out from the blowing air passage 1b.
At this time, the air on the upper side of the blowing air path 1b is blown while being guided by the upper flap 2, and the air on the lower side of the blowing air path 1b is sequentially guided to the lower upstream flap 31 and the lower downstream flap 32. It will be blown out while.
[0023]
Therefore, at this time, the shaft 7a of the lower drive motor 7 that drives the upper flap 2 and the lower downstream flap 32 is rotated, and the upper flap 2 and the lower downstream flap are rotated via the lower crank mechanism 8 attached to the shaft 7a. The vertical direction of the air blown from the blow-out air passage 1b is set to the target direction so that the inclination angle of the flap 32 becomes the target direction.
[0024]
At this time, the shaft 9a of the upper drive motor 9 for driving the lower upstream flap 31 is rotated, and the inclination angle of the lower downstream flap 31 is set to the target blowing direction via the lower crank mechanism 10 attached to the shaft 9a. (Angle) and the angle of inclination of the air path 1b.
[0025]
As a result, the air on the upper side of the blowing air path 1b is blown out while being guided by the upper flap 2, and the air on the lower side is gradually guided to the target direction while being guided by the lower upstream flap 31 and the lower downstream flap 32. It will be changed so that it will be blown out smoothly.
[0026]
In the above description, three flaps are driven by two drive motors. However, a drive motor may be provided for each flap and moved.
Alternatively, three flaps may be driven by two drive motors without inserting one shaft of the drive motor into the rotation shaft 32b driven by the other motor.
That is, although the mounting space is increased, the shaft 9a of the upper drive motor 9 is directly mounted on the rotating plate 31a of the lower upstream flap 31, and the upper drive motor 9 directly rotates the lower upstream flap 31. Is also good.
[0027]
As described above, when the direction of the air blown from the air passage 1b, particularly the direction of the air on the lower side is changed, the air is gradually and gradually directed to the target direction (angle). Since the resistance is reduced, it is possible to obtain an up-down wind direction device and an air conditioner using the same with less air volume reduction and wind noise.
[0028]
Also, since the lower drive motor rotates the upper flap and the lower downstream flap via the lower link mechanism, and the upper drive motor rotates the lower upstream flap via the upper link mechanism, the lower drive motor rotates the lower flap. Since two wind direction flaps are rotated by two drive motors, an installation space is small, and an economical vertical wind direction device and an air conditioner using the same can be obtained.
[0029]
Also, at this time, the shaft of the upper drive motor rotates the lower upstream flap via the hollow rotation shaft of the lower downstream flap rotated by the lower drive motor, so that the three wind-direction flaps are concentric. Since it rotates in the above two shaft spaces, an up-down airflow direction device with less installation space and an air conditioner using the same can be obtained.
[0030]
At this time, as shown in FIG. 3, for example, a quadrangular, trapezoidal, or triangular projection is provided on the outer surface of the hollow rotary shaft 32 b of the lower downstream flap 32, and the projection is engaged with the projection of this shape. The lower link mechanism 7 is provided with a projection engaging hole 7a, and a triangular projection is inserted into the projection engaging hole 7a to determine the mutual positions of the hollow rotary shaft 32b and the lower link mechanism 7 and to form the lower link. Since the movement of the mechanism 7 is transmitted to the hollow rotation shaft 32b to rotate the lower downstream flap 32, the positioning means has a transmission function and a positioning function, so that the number of constituent parts can be reduced. Assembly can be performed, and torque can be transmitted reliably.
[0031]
Further, as shown in FIGS. 6 and 10, the upper link mechanism 10 for rotating the rotation shaft 31b of the lower upstream flap 31 is provided with the cover 13 so as to be exposed to the blowing air passage 1b. When the cover is covered, the user's hands and the like are not caught by the upper link mechanism 10 and foreign matter and the like are not caught by the upper link mechanism 10, so that a safe and highly reliable vertical wind direction device and an air conditioner using the same can be obtained. .
[0032]
Embodiment 2 FIG.
In this embodiment, a connecting mechanism between the lower upstream flap 31 and the lower downstream flap 32 in the first embodiment will be described with reference to FIGS.
FIG. 7 is an overall configuration diagram of a connection mechanism between the lower upstream flap 31 and the lower downstream flap 32, and FIG. 8 is a detailed view of the connection mechanism.
[0033]
As shown in FIG. 8, a lower engagement plate 32e having an engagement shaft 32f is provided at a predetermined interval on the lower downstream flap 32, and the engagement shaft 32f is inserted into one lower upstream flap 31. An engagement hole 31c is provided, and the lower upstream flap 32 and the lower downstream flap 31 are rotatable by inserting an engagement shaft 32f into the engagement hole 31c.
[0034]
The lower upstream flap 31 is provided with a lower engagement plate having an engagement shaft, the lower downstream flap 32 is provided with an engagement hole, and the lower upstream flap 31 and the lower downstream flap 32 are rotatable. You may do it.
With the above-described configuration, the relative movement of each other is smooth, and the strength is increased, so that a highly reliable vertical wind direction device can be obtained.
[0035]
Embodiment 3 FIG.
In the third embodiment, the mounting structure of the upper flap 2 and the lower downstream flap 32 with respect to the blow-out air passage in the first or second embodiment will be described with reference to FIGS. 3, 9, and 10. FIG.
First, in FIGS. 3A and 3B, reference numeral 32 denotes a lower downstream flap for adjusting the vertical direction in the blow-out air passage 1b; 32a, a downstream rotary plate attached to the right end of the lower downstream flap 32; The hollow rotary shaft 32b is attached to the side flap rotary plate 32a. The hollow rotary shaft 32b is rotatable and detachable in the mounting hole 1c in the side wall surface of the blow-out air passage 1b via the lower link mechanism. As shown in FIG.
[0036]
An attachment mechanism as shown in FIG. 9 is provided at one end of the left end of the lower downstream flap 32. The lower flap 32c is provided at the left and right ends of the lower upstream flap 32. The lower flap mounting mechanism 32c includes a mounting plate 32d mounted on the lower downstream flap 32 and having a shaft insertion hole 32f, and a mounting shaft 32e inserted into the shaft insertion hole 32f of the mounting plate 32d. After the mounting shaft 32e is inserted into the shaft insertion hole 32f, the mounting shaft 32e is inserted into the mounting hole 1c on the side wall surface of the blowing air passage 1b, and the lower downstream flap 32 is mounted on the left wall surface of the blowing air passage 1b. It is attached rotatably via.
[0037]
Therefore, by pulling out the mounting shaft 32e of the mounting mechanism 32c, the lower downstream flap 32 comes off the air path wall surface 1a.
At this time, as described above, since the lower upstream flap 31 is attached to the lower downstream flap 32 via the connection mechanism, the lower upstream flap 31 also comes off together.
[0038]
On the other hand, the upper flap 2 connected to the lower downstream flap 32 via the lower link mechanism also has an upper flap rotating plate 2a attached to the right end side of the upper flap, The upper flap rotation shaft 2b attached to 2a is configured to be rotatable and detachable in an attachment hole 1c on the right wall surface of the blow-out air passage 1b.
[0039]
At the left end of the upper flap 2, a mounting mechanism similar to that described above, that is, a mounting plate 2 d having a shaft insertion hole 2 e attached to the upper flap 2 and a shaft insertion hole 2 e of the mounting plate 2 d are provided. A mounting mechanism including a mounting shaft 2f to be inserted is provided. After the mounting shaft 2f is inserted into the shaft insertion hole 2e of the mounting plate 2d, the mounting shaft 2f is further mounted to the mounting hole 1c on the left wall surface of the blow-out air passage 1b. And the upper flap 2 is rotatably attached to and detachable from the side wall surface of the outlet air passage 1b.
Therefore, the upper flap 2 can be removed from the air path wall surface by pulling out the mounting shaft 2e of the mounting mechanism 2c.
[0040]
Although not shown, the mounting shaft of the mounting mechanism is configured to be inserted into the insertion hole and then detachably fixed to the flap via the locking portion with one touch.
[0041]
As described above, since the attachment device pivotally and detachably attaches the upper flap 2 or the lower upstream flap 32 to the side wall surface of the blow-out air passage 1b, the flap can be easily cleaned, so that the air that can be easily cleaned is provided. A harmony machine is obtained.
In particular, when the lower upstream flap 32 is removed, the lower upstream flap 31 connected to the lower downstream flap 32 via the connection mechanism is also removed, so that an air conditioner that can easily perform flap cleaning is obtained.
[0042]
【The invention's effect】
As described above, in the present invention,
In a vertical wind direction device having upper and lower flaps arranged in parallel in an air passage and respectively changing upper and lower flaps of upper and lower air flows blown from the air passage, the lower flap includes the wind A lower downstream flap for changing the vertical direction of the downstream airflow on the downstream side, and a lower upstream flap for changing the vertical direction of the upstream of the airflow lower airflow. Since the vertical direction of the airflow on the lower side of the path is gradually changed, even if the direction of the air blown out from the air path, especially the vertical direction of the air on the lower side is changed, the air is smooth. Since the resistance due to the change of the flow and the wind direction is reduced, it is possible to obtain a vertical wind direction device and an air conditioner using the same, which reduce the air volume and the wind noise.
[0043]
Further, a lower drive device rotates the upper flap and the lower downstream flap via a lower link mechanism, and an upper drive device rotates the lower upstream flap via an upper link mechanism. Therefore, since three wind direction flaps can be rotated by two drive motors, an installation space is small and an economical vertical wind direction device can be obtained.
[0044]
Also, since the shaft of the upper driving device penetrates through the hollow rotation shaft of the lower downstream flap that the lower driving device rotates via the lower link mechanism, and rotates the lower upstream flap, Since the three wind direction flaps can be rotated in two axial spaces, a compact vertical wind direction device with a smaller installation space can be obtained.
[0045]
In addition, since a connecting mechanism is provided on each of the lower upstream flap and the lower downstream flap, and the two flaps are rotatably connected to each other, the relative movement between the flaps is smooth and the strength is increased. Therefore, a highly reliable vertical wind direction device can be obtained.
[0046]
Further, since the mounting mechanism is provided at each of both ends of the lower downstream flap or the upper flap, and the flap is rotatably attached to and detachable from both side walls of the blow-out air path, the movement of the flap is impaired. Therefore, an air conditioner that is easy to clean can be obtained.
[0047]
In addition, since the cover is provided so as to cover the upper link mechanism, a hand or the like of the user is not caught by the upper link mechanism, and a foreign substance or the like is not caught by the upper link mechanism. A device is obtained.
[0048]
In addition, since the indoor unit of the air conditioner uses the vertical wind direction device according to any one of claims 1 to 6, the direction of the air blown from the air path, particularly, the vertical direction of the lower air. Even if the direction is changed, the air flows smoothly and the air path resistance is reduced, so that an air conditioner with less air volume and less wind noise can be obtained.
