Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to improve the air conditioning effect of an air conditioner (hereinafter referred to as the air conditioner) by changing the blowout pattern of the airflow from the outlet of the air conditioner by rotating a single shaft. It is an object of the present invention to provide a flow direction control device that can change the direction of the flow direction and obtain more deflection angles with a small storm volume reduction rate.

A conventional flow direction control device will be explained with reference to FIGS. 1 to 3.

1 is an air conditioner main body, 2 is an air outlet configured by a subordinate flow direction control device consisting of a plurality of louvers, and 3
4 is a fan (sirocco fan) for blowing air, 5 is a heat exchanger, and 6 is a casing.

The flow sucked in from the suction port 3 by the fan 4 is heated or cooled by the heat exchanger 5, and the direction is changed by the louver at the blow-off port 2 and is blown into the room to be air-conditioned, thereby performing air conditioning. 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 flow is deflected up and down by multiple louvers (see Figure 3). (shown here), when the flow is deflected, the airflow resistance increases and the airflow loss increases, making it impossible to obtain a sufficient air conditioning effect.

In addition, recently there has been a desire to improve comfort by blowing out air-conditioning air by changing the pattern of the blowout flow, such as a slow, soft flow, or, conversely, a slow, slow flow. It is coming. In view of this point, the present invention includes a first guide wall and a second guide wall that are configured to have a shape that gradually expands in the direction of the flow and are opposed to each other and that are configured to allow the flow to adhere to the control plate axis. a control plate that rotates to control the adhesion of the flow to the first and second guide walls; and a control plate that is provided as a part of at least one of the first and second guide walls, and that is centered about the auxiliary plate axis. an auxiliary plate that rotates as a auxiliary plate, and an auxiliary plate that rotates in the same direction as the control plate when the control plate is tilted to a certain angle; By configuring the board with a linkage mechanism that rotates the board in the opposite direction to the control board, it is possible to increase the air conditioning effect with less air volume loss, a larger deflection angle, and to meet human preference. To provide a flow direction control device that can arbitrarily change the blowout pattern according to the flow direction and can perform a swing operation while changing the blowout pattern by swinging a single shaft. An embodiment of the present invention will be described based on FIGS. 4 to 12.

In FIGS. 4 and 5, 7 is an air conditioner body, 8 is an air outlet, 9 is an air suction port, 10 is a sirocco fan, 11 is a heat exchanger, and 12 is a flow direction control device of the present invention. . The flow direction control device 12 includes a first guide wall 13 located at the top and having a gradually expanding shape, a second guide wall 14 located at the bottom and having a gradually expanding shape, and a horizontal control plate axis 16 as the center. The rotating control plate 15 is explained as a part of the first guide wall 13, and the auxiliary plate 17 rotates around the auxiliary plate axis 18 (this auxiliary plate 17 may also be provided on the second guide wall 14 side). (good), a step 19 provided on the second guide wall 14 (this step 19 is not necessary when the auxiliary plate 17 is provided), and a linkage mechanism 2 shown in FIG.
Consists of 0. 6 to 8, the cooperation mechanism 20 is constituted by a rotation transmitting section 21 attached to the control plate shaft 16 and an auxiliary plate rotating member 22 attached to the auxiliary plate shaft 18. The auxiliary plate rotating member 22 is provided with inclined surfaces 22a, 22b, and 22c. 2
Reference numeral 3 denotes a control plate rotation lever attached to the opposite side of the control plate shaft 16, and the control plate 15 is configured to be rotated by moving this lever.

24 is a swinging mechanism, and as shown in FIG.
6 and converts the rotation of the motor 25 into a swinging motion of the control plate shaft 16.

Various mechanisms such as a link mechanism may be used as the swing mechanism 24, but the explanation thereof will be omitted. In the above configuration, when the control plate rotation lever 23 is moved to rotate the control plate 15,
The rotation transmission member 21 rotates together with the control plate 15. As a result, the tip of the rotation transmitting member 21 comes into contact with the inclined portions 22a to 22c of the auxiliary plate rotating section 22, thereby rotating the auxiliary plate 17. At this time, if the tip of the rotation transmission member 21 is in contact with the oblique part 22a of the auxiliary plate rotation member 22, the control plate 1
5 and the auxiliary plate 17 rotate in the same direction, and when they are in contact with 22b, the control plate 15 and the auxiliary plate 17 rotate in the opposite direction;
2c, the auxiliary plate 17 is in contact with the first guide wall 1
It operates as configured as part of 3. That is, by rotating the control plate rotation lever 23, the control plate 15 and the auxiliary plate 1 are rotated.
7 performs the following combination of operations. First, when the control plate rotation lever 23 is turned upward, that is, when the control plate 15 is turned upward, as shown in FIG. It will not rotate until Next, when the control plate rotation lever 23 is gradually turned downward, the rotation transmission member 21 comes into contact with the inclined part 22a of the auxiliary plate rotation member 22, and during this time, the control plate 15 and the auxiliary plate 17
are rotated in the same direction to form a combination as shown in FIG. If you tilt the control plate rotation lever 23 further down,
The tip of the rotation transmitting member 21 comes into contact with the inclined portion 22b' of the auxiliary plate rotating member 22, and at this time, the auxiliary plate 17 rotates in the opposite direction of the control plate 15, and finally the auxiliary plate 15 is rotated as shown in FIG. becomes a part of the first guide wall 13. The change in the blowout flow at this time will be explained. First, in the case of the combination shown in FIG. 9, the control plate 15 and the first guide wall 13
The flow between the two (referred to as the flow above the control plate) is bent by the control plate 15 in the direction of adhering to the first guide wall 13.

As a result, the flow above the control plate 15 is directed to the first guide wall 13.
It adheres to the surface, deflects it upward, and flows out. On the other hand, the control board 15
The flow between the guide wall 14 and the second guide wall 14 (referred to as the flow below the control plate) interferes with both the flow above the guide wall 14 and the control plate 15. Since a step 19 is provided on the upstream side of the control plate 14, the adhesion becomes thicker, and since the attracting force of the flow above the control plate 15 is larger, the flow below the control plate 15 is It merges with the flow of the upper leg of the control plate 15, adheres to the first guide wall I3, and blows out with a velocity distribution as shown in FIG. Next, in the case of the combination shown in FIG. 10, the flow below the control plate 15 is bent by the control plate 15 in the direction of adhering to the second guide wall 14.

As a result, the flow below the control plate 15 is directed to the second guide wall 14.
It adheres to the surface, deflects downward and flows out. On the other hand, control board 1
5 is directed to the second guide wall 14 by the auxiliary plate 17.
Since it is directed to the side, it merges with the flow below the control plate 15, adheres to the second guide wall 14, and blows out with a velocity distribution as shown in FIG. Next, in the case of the combination shown in FIG. 11, the flow below the control plate 15 is bent by the control plate 15 in the direction of adhering to the second guide wall 14. As a result, the flow below the control plate 15 adheres to the second guide wall 14, is deflected downward and flows out. On the other hand, the flow above the control plate 15 interferes with both the first guide wall 13 and the flow below the control plate 15. Since such a step 19 is not provided and the angle of the control plate 15 is large to a certain extent, the flow above the control plate 15 is not induced by the flow below the control plate 15. . It attaches to the first guide wall 13. As a result, the upper flow and lower flow of the control plate 15 adhere to the first guide wall 13 and the second guide wall 14, respectively, and flow out. However, since these two flows interfere with each other, they are blown out as one velocity distribution that spreads vertically as shown in FIG. In this case, since the control plate 15 faces downward, the overall velocity distribution is biased downward. The above operation changes the blowout direction and distribution. As described above, the present invention includes a first guide wall and a second guide wall that are configured to have a shape that gradually expands in the direction of the flow and are opposed to each other, and that are arranged around the control plate axis to allow the flow to adhere. a control plate that rotates to control the adhesion of the flow to the first and second guide walls; and a control plate that is provided as a part of at least one of the first and second guide walls, and that is centered about the auxiliary plate axis. an auxiliary plate that rotates as a auxiliary plate; and when the control plate is tilted to a certain angle, the auxiliary plate is rotated in the same direction as the control plate, and when the control plate is tilted to an angle greater than the certain angle, the auxiliary plate is The structure includes a cooperation mechanism that rotates the plate in the opposite direction to the control plate, and the guide wall 13,
Since it uses the effect of fluid adhesion to 14,
The flow can be deflected without the air volume decreasing suddenly like in the case of a secondary tank. Further, when the motor 25 is rotated and the control plate 15 is oscillated using the oscillation mechanism 24, changes in the balloon pattern as shown in A to D in FIG. 12 can be obtained. Therefore, the blowout pattern can be changed only by uniaxial rocking, improving operability and comfort. Although not shown in the figure, if an auxiliary plate 17 is also provided on the side of the second guide wall 14, a blowout pattern that is vertically symmetrical to the velocity distribution shape shown in FIG. 11 can be added. Therefore, when used as the air outlet of the air conditioner of the flow direction control device 12 described above, the direction and distribution of the air conditioned flow can be arbitrarily changed with a simple operation, and a large deflection can be achieved without changing the air volume much. Since it is possible to blow out the air conditioning flow at an angle, a great air conditioning effect can be obtained.

As is clear from the above description, the flow direction control device of the present invention achieves the following effects by utilizing the cooperative operation of the control plate and the auxiliary plate to achieve the effect of the flow adhering to the guide wall.

When the flow is attached to the guide wall and deflected, since the deflection uses the Coanda effect, the rate of decrease in air volume is small.
A large deflection angle can be obtained, and when this is applied to an air conditioner, the temperature distribution in the room to be air conditioned is improved, and air conditioning and energy saving effects can be obtained.

'21 Since the speech bubble pattern can be changed by simply rotating one shaft, the desired speech bubble pattern can be obtained with simple operation, and by connecting a swinging mechanism to the shaft and swinging the shaft, It is possible to obtain a speech bubble form in which the speech bubble pattern changes sequentially.

As a result, operability and comfort are improved.
