Description

Detailed Description of the Invention The present invention provides an air conditioner in which when the inlet flow to the outlet is inclined with respect to the center of the outlet or is biased to one side, the outlet flow is adjusted to the inlet flow. When deflecting the air significantly, blow out at a large deflection angle and with little reduction in air volume, and when blowing out in almost the same direction as the inlet flow,
It is an object of the present invention to provide a flow direction control device that configures an air conditioning outlet that can blow air with even less reduction in air volume.

A conventional flow direction control device will be explained with reference to FIGS. 1 to 3. 1 is the main body of the air conditioner, 2 is an air outlet configured by a conventional flow direction control device consisting of a plurality of louvers, 3 is an air inlet, 4 is a fan (Shirotskov fan) that sends out the flow, and 5 is an air outlet. In the heat exchanger, 6 is a casing. The flow sucked from the suction port 3 by the fan 4 is heated or cooled by the heat exchanger 5,
Air conditioning is performed by changing the direction at the air outlet 2 and blowing air into the air. Generally, in order to equalize the temperature distribution in an air-conditioned room and improve the air conditioning effect, it is necessary to bend the air flow downward during heating and upward during cooling. However, in the air conditioner with the above configuration (generally, floor-standing devices have this configuration), the air flows upward from the fan provided at the bottom, so the air flows into the air outlet 2. The flow is slightly upward, as shown by the arrow in the figure. Therefore, if you try to make the air blow downward during heating, it will cause a large deflection to the inlet flow, as shown in Figure 3, and most of the air will collide with the louvers and be bent. Therefore, there is a problem in that the air volume loss becomes extremely large, leading to a decrease in air conditioning effectiveness.

The present invention provides a flow direction in which the flow is deflected by a guide wall that makes the flow adhere using the Coanda effect, a control plate that controls the adhesion of the flow, and a bias plate that operates in conjunction with the control plate. By configuring the air outlet using a control device, the drawbacks of the conventional air conditioner can be overcome, and even during cooling, it is possible to improve the air conditioning effect by further reducing the air flow resistance.

4 to 11 regarding one embodiment of the present invention.
This will be explained in the figure. Reference numeral 7 denotes the air conditioner main body, and 8 indicates the outlet configured by the flow direction control device of the present invention (the part surrounded by a dashed line, which is integrated with the casing. For convenience, it is not incorporated in this way. ), 9 is a suction port, 10 is a fan, 11 is a heat exchanger, and 12 is a control plate that rotates around the control plate axis of 13, coaxially and simultaneously with the dial 104. It is configured to rotate. 14 is 1
This is an auxiliary plate that rotates around the auxiliary plate axis No. 5. 16 and 17 are a lower guide wall (second guide wall) and an upper guide wall (first guide wall);
2 and the auxiliary plate 14 are rotated so that the flow adheres thereto. Further, the upper guide wall 17 is provided with an auxiliary plate case 18, so that when the auxiliary plate 14 faces upward (outside the flow), the auxiliary plate does not obstruct the flow from adhering to the upper guide wall 17. It is composed of Further, as shown in FIGS. 6 and 7, a control plate rotation transmission member 19 is provided on the side of the control plate shaft 13 facing the dial 104, and an auxiliary plate rotation member 20 is provided on the auxiliary plate shaft 15. is provided. Between the above two members, a displacement member 22 is supported by a support member 23 fixed to the main body wall surface and slides up and down, thereby directing the rotation of the control plate rotation member 19 to the auxiliary plate rotation member 20. It is structured to communicate. In addition, the displacement member 22
A stripper 22a is provided at the eighth
As shown in the figure, when the downstream side of the control plate 12 faces above the horizontal, the auxiliary plate 14 is connected to the auxiliary plate case 1.
8 and is fixed. Further, as shown in FIG. 6, the lower end of the displacement member 22 is in contact with the left end of the control plate rotation transmission member 19, while the upper end is in contact with the vicinity of the rotation center of the auxiliary plate rotation member 20. As a result, the bias plate 14 is given a rotation angle that is larger than the rotation angle of the control plate 12. Further, a weight 21 is connected to the left end of the bias plate rotating member 20,
The auxiliary plate 14 is set to be housed within the auxiliary plate case 18 whenever the displacement of the displacement member 22 is not transmitted.

The operation in the above configuration will be explained. First, during heating, that is, when performing downward blowing, the control plate 12 is slightly tilted toward the lower guide wall 16 (second guide wall) as shown in FIG. As a result, the control plate rotation transmission member 19 rotates as described above, and the rotation reaches the auxiliary plate rotation member 20 by the displacement member 22, and the auxiliary plate 1
4 faces downward (inside the flow). In this state, the fifth
When the flow is blown out as shown in the figure, the flow below the control plate 12 is controlled by the control plate 12 and adheres to the lower guide wall 16 due to the Coanda effect. In addition, the flow above the control plate 12 is controlled by the auxiliary plate 14.
Because part of the flow is directed downwards by
The upper flow approaches the lower flow, and as a result, the upper flow is attracted to the lower flow by the fluid entrainment action, and these two flows together move toward the lower guide wall 1.
6 and flows. At this time, since the lower guide wall 16 is shaped to gradually incline downward, the flow attached to it acts gradually downward,
This results in a significant downward deflection of the flow. In this case, the deflection operation utilizes the properties of the fluid itself, such as the flow entrainment attraction effect and the Coanda effect, so unlike deflection by colliding with a louver etc., there is almost no loss in air volume, and the air conditioning effect is almost unchanged. It becomes possible to deflect the flow downward without reducing it.

Next, as shown in Figure 9, adjust the angle of the control plate to the fifth position.
A case where the camera is oriented slightly upwards compared to the case shown in the figure will be explained. In this case, the auxiliary plate 14 is oriented substantially horizontally due to the above-described operation. Since the original flow is an upward flow, the control plate 12 is directed slightly downward, but the exit flow is a nearly horizontal flow. In this case, there is almost no adhesion to the guide wall.

Next, as shown in FIG. 10, when the control plate 12 is placed horizontally, the auxiliary plate 14 is accommodated in the auxiliary plate case 18, so that the flow adheres to the upper guide wall 17. However, in this case, since the control plate 12 is oriented horizontally, it is difficult for the flow below the control plate to merge with the flow above the control plate. Blows out in the direction you face.

Next, when the control plate 12 is tilted slightly upward as shown in FIG. 11, the flow is completely attached to the upper guide wall 17, so that the flow is deflected significantly upward and flows out. At this time, the control plate 12 is in almost the same direction as the direction of the incoming flow, and
Since the auxiliary plate 14 is housed in the auxiliary plate case 18, almost no air flow resistance occurs. Therefore, compared to conventional louvers, the deflection angle becomes larger and the air flow resistance is reduced, resulting in a greatly increased air conditioning effect.

As described above, when controlling the direction of the air flow in a device that has a configuration in which the flow is inclined upward and flows into the air outlet, when the flow is deflected downward during heating, that is, when the flow is downwardly blown, the conventional louver is There was a problem that the air volume decreased significantly and the air conditioning effect deteriorated, but as in the present invention, the flow is attached to the guide side using a control plate and an auxiliary plate, and the flow is deflected by the action of the fluid itself. By doing so, it becomes possible to cause a downward deflection with almost no decrease in air volume. In addition, during cooling, that is, when deflecting upward, in conventional louvers, eddies occur on the downstream side of multiple louvers, so a certain amount of air volume loss is inevitable, but in the flow direction control device of the present invention, The bias plate fits into the guide wall and no longer acts as a resistance to the flow, so only one control plate affects the reduction in air volume. Therefore, as compared to the conventional case, the air volume is increased, and since the flow is attached to the upper guide wall and deflected, the deflection angle is also increased compared to the conventional case, so that the air conditioning effect can be increased.

Further, as described above, since the flow is deflected by the properties of the fluid itself, the rotation angle of the control plate 12 may be small, and the operation is easy.

As is clear from the above description, the flow direction control device of the present invention includes a guide wall for attaching a flow using the Coanda effect, a control plate for controlling the attachment of the flow, and an operating means for rotating the control plate. Since it is configured to deflect the flow by the control plate and the auxiliary plate that cooperate with each other by the cooperative mechanism, when this is applied to the outlet of an air conditioner,
It has the following effects.

(1) During heating, that is, when performing downward blowing, the flow can be significantly deflected downward without increasing the air flow resistance, and a great air conditioning effect can be obtained.

(2) When performing air conditioning, that is, when performing top blowing, the air flow resistance is reduced compared to conventional louvers.
Moreover, it becomes possible to greatly increase the deflection angle, and the air conditioning effect can be greatly increased.

(3) Since a linkage mechanism is provided, directional control can be performed by simply rotating a single control plate using the operating means, improving operability.
