CONSTITUTION:A device comprises a guide wall 2 promoting air to adhesively and deflectively flow and an adhesion control part 6 controlling flow adhesion of the air to the guide wall 2. A deformation part 8 is provided in a part of the guide wall 2, and this deformation part 8 is formed so as to be deformed in a direction along the guide wall 2 when a temperature of the flowing air is higher than the prescribed level while in a direction to check dew condensed water when the temperature of the flowing air is lower than the prescribed level. In this way, the air, when it is warm, is promoted to flow in an adhesive condition to the guide wall 2, while the air, when it is cool, never causes the dew condensed water to drip enabling it to be processed by a water processing hole 9.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a flow direction control device that is installed at an air outlet of an air conditioner or the like and deflects the flow from an air source in an arbitrary direction. It is something.

Conventional configuration and its problems In air conditioners that perform cooling and heating, the direction of air flow is controlled to blow downward during heating and horizontally during cooling, in order to equalize the temperature distribution in the room being air-conditioned. This is desirable. However, in order to improve comfort, it is necessary to locally cool air by blowing mist or downward flow during cooling, or to perform swing motion over a wide range. An example of a conventional flow direction control device for this purpose is shown in FIG. In the figure, 1 is a flow inlet, 2 is a guide wall for attaching and deflecting the flow, and 3 is a control blade which rotates around an axis 4. Reference numeral 6 denotes a bias projection which has the function of promoting the adhesion of the flow to the guide wall 2. The control blade 3, shaft 4, and bias protrusion constitute an adhesion control section 6. In this configuration, the flow entering from the inlet 1 can change the degree of adhesion to the guide wall 1 according to the rotation of the control vane 3 of the adhesion control unit 6, and is deflected over a wide angle from horizontal to downward with almost no change in air volume. be done. At this time, the bias protrusion 6 serves to promote the flow to adhere to the guide wall 2. By deflecting the flow over a wide angle through the above operation,
During heating, the flow is deflected downward without substantially reducing the air volume (as shown by the broken line in Figure 1), and during cooling, the flow is blown out horizontally.

As a result, the temperature distribution within the air-conditioned room can be made uniform. However, if you want to use it more comfortably, that is, if you want to blow the air slightly downward to hit the body with cold air during cooling, or if you want to swing over a wide range, the above configuration will cause condensation to occur due to the entrainment of the air. There is a problem with water forming downstream of the guide wall and dripping onto the floor below. For this reason, during cooling, the flow could only be directed downward within a range of 30° to 4o0 from the horizontal. In addition, there is a device in which a dew condensation treatment member 87 is provided at the end of the guide wall in order to treat dew condensation water, but when this is provided, adhesion of the downward flow to the guide wall 2 during heating is inhibited, There was a problem that it could not be deflected sufficiently.

OBJECT OF THE INVENTION The present invention solves such conventional problems by providing a deformable part in a part of the guide wall and configuring it to deform according to the blowing temperature of the flow. It promotes the flow of water to the guide wall and dams up condensed water during cooling. As a result, warm air is deflected downward over a wide angle during heating, and even when air is blown horizontally downward during cooling, no dripping of condensed water occurs, making the air conditioner more comfortable to use. The purpose is to increase

Structure of the Invention In order to achieve this object, the present invention includes a guide wall for adhering and deflecting a flow, and an adhesion control section for controlling adhesion of the flow to the guide wall, and a part of the guide wall. is provided with a deformable portion, and the deformable portion is configured to deform in a direction along the guide wall when the temperature of the flow is higher than a predetermined temperature, and in a direction to dam the condensed water when the temperature is lower than the predetermined temperature. This is what I did.

With this configuration, dew condensation water generated by flow induction during cooling is treated in the deformed part, so that
There is no need to worry about dripping, and the flow can be directed in any direction from horizontal to downward during cooling. In addition, during heating, the deformed portion deforms in the direction along the guide wall, so that the flow is blown downward at a wide angle with almost no change in air volume due to the adhesion effect of the flow.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. In the figure, 1 to 6 are the same as in the conventional example. Further, there are various types of adhesion control unit 6 other than those shown in the figure, but any type may be used as long as it controls the adhesion state of the flow to the guide wall 6. 8 is a deformed portion provided in a part of the guide wall 6, and is formed of a shape memory alloy or a bimetal. In this figure, the deformed portion 8 is provided at the downstream end of the guide wall where it is most effective. Reference numeral 9 denotes a water treatment hole, which guides the condensed water blocked by the deformed portion 8 to a drain treatment portion or the like through a water conduit 10.

The operation in the above configuration will be explained. If the flow entering the inlet 1 is warm air, the flow will adhere to the guide wall 2 by tilting the control vane 3 slightly downward (as shown by the dashed line in FIG. 3). At this time, the deformable portion 8 is heated by the hot air and deformed into the shape shown by the dashed line in FIG. Therefore, the adhesion area of the guide wall 2 increases, the adhesion of the flow to the guide wall 2 is further promoted, the deflection angle is further increased, and the blowout velocity distribution becomes uniform. As a result, the temperature distribution in the air-conditioned room is approximately 41 times more uniform, resulting in a comfortable heating condition.

Next, a case where the flow is cold air will be explained. in this case,
If the purpose is to make the temperature distribution uniform in the air-conditioned room,
By setting the adhesion control vanes 3 horizontally, the flow is blown out horizontally. ′! In addition, if you want to direct the flow downward to apply cold air to the human body, or if you want to send cold air to a wide space by swinging at a wide angle, you can direct the adhesion control blades 3 downward, but in this case, the flow It will adhere to the guide wall 2.

As a result, condensed water is generated on the guide wall surface due to the flow attraction. On the other hand, since the deformed portion 8 provided on the guide wall 2 is not heated by the warm air, it takes the shape shown by the solid line in FIG. 3. As a result, the flow of condensed water generated on the guide wall surface is blocked by the deformed portion 8, preventing its dripping, and is sent to a drain treatment portion or the like through the water treatment hole 9.

Therefore, even if the flow is directed significantly downward (600 to 6o0), no dripping of condensed water occurs, so that blowing can be carried out in any direction with peace of mind.

Effects of the Invention As described above, the flow direction control device of the present invention provides the following effects.

A part of the guide wall of the flow direction control device that uses the adhesion effect to the guide wall to deflect at a wide angle is equipped with a deformable part that deforms according to the temperature of the air outlet. While deforming along the air conditioner to ensure a sufficient downward deflection angle, during cooling, the deformed part completely processes dew condensation water, making it possible to deflect the flow direction downward over a wide angle. You will be able to use air conditioners etc. very comfortably.
