[0005]

[Problems to be solved by the invention]

 Since the conventional outlet device was configured as described above, the outlet angle was fixed diagonally downward regardless of cooling and heating, resulting in a constant oblique airflow. In addition to the lack of general versatility, the airflow in the horizontal or vertical direction is shorter than in the case where the airflow is changed to the optimum airflow pattern for cooling and heating and the airflow is blown in the appropriate airflow direction. There was a problem that it was difficult to uniformly cool or heat the room to be air-conditioned.

[0006] The outer cone portion 101b of the opening frame body 101 is a part shared with other ceiling outlets, and is used in a horizontal direction substantially parallel to the ceiling when used for a horizontal outlet. In general, the divergence angle is often set to a shallow angle of about 30 ° in order to blow out the conditioned air smoothly, and since this is used as it is, a portion with a small gap with the middle cone 102 occurs, and the airflow is reduced. However, there was a problem that the speed was increased and noise was generated.

[0007] The present invention has been made to solve the above-mentioned problems, and can easily adjust the position of the airflow guide portion and the angle of the airflow deflector, and change the blowing pattern to optimize the optimal air according to the temperature of the conditioned air. It is an object of the present invention to provide an air outlet device that can achieve harmonic performance and generate less noise.

[0008]

[Means for Solving the Problems]

 The outlet device according to the present invention has an opening area to which air conditioning gas is supplied and blows the gas into a space to be air-conditioned, and expands around the opening toward the indoor blowing side. An opening frame body having an outer cone portion formed in a shape thereof, and an edge portion standing substantially perpendicular to an opening surface formed at a lower end of the outer cone portion; and a lower end in an opening region of the opening frame body. A position is provided so as to be adjustable in two positions, a height position where the position substantially coincides with the lower end of the edge portion, and a height position which is raised from the position by the edge height, and an expansion portion facing the inner side surface of the outer cone portion. An airflow guide formed of a blade body having an open side surface, for guiding the airflow blowing direction between the blade body and the opening frame body in two predetermined directions, and contact with the airflow of the airflow guide section. Part, with one side along the surface of the airflow guide part across a predetermined folding curve A substantially plate-shaped airflow deflector plate that is fixed and the other side is bent so as to be adjustable in angle with respect to one side, and is disposed on the upstream side of the airflow guide in the opening area of the opening frame. And a deflector plate that blocks the airflow at the center of the airflow passage and deviates the airflow toward the outer periphery of the airflow passage. As described above, according to the present invention, the position of the airflow guide portion with respect to the opening frame and the bending angle of the other side of the airflow deflector are adjusted to change the airflow blowout direction. As a result, it is possible to improve the air-conditioning ability, to easily adjust the blowing direction, and to perform complicated operations without requiring complicated operations.

In addition, the air outlet device according to the present invention may be configured such that the airflow deflector plate is, as required, a substantially plate made of a shape memory alloy in which the other side of the bent curve stands up or down depending on the temperature of the airflow. It is formed as a body. As described above, according to the present invention, the airflow deflecting plate automatically rises or falls down in response to a change in the temperature of the airflow to change the blowout pattern, thereby making it almost unnecessary for the operator to adjust the blowout direction. In addition, significant labor savings can be achieved.

In addition, the air outlet device according to the present invention is disposed, if necessary, with its ends fixed to one side and the other side of the airflow deflector sandwiching the fold curve, so that the airflow temperature can be controlled. An auxiliary plate of a substantially plate-shaped body made of a shape memory alloy, which is deformed accordingly to raise or lower the other side of the airflow deflection plate. As described above, according to the present invention, the airflow deflecting plate is moved by the auxiliary plate to automatically change the airflow pattern according to the temperature of the airflow. The work can be greatly reduced in labor, and the cost can be reduced by suppressing the use of the shape memory alloy.

In addition, in the blow-out device according to the present invention, the outer cone portion of the opening frame is formed such that the inclination angle at which the opening expands is in the range of 35 ° to 45 ° with respect to the opening surface. It is a thing. As described above, according to the present invention, by adjusting the angle of the outer cone portion, the interval between the outer cone portion and the airflow guide portion is widened to suppress the speed of the airflow, thereby increasing noise such as wind noise. In addition to being able to reduce airflow, the airflow guidance performance is improved, and corner blowing can be performed reliably.

Further, in the air outlet device according to the present invention, if necessary, the airflow deflector plate is rounded at a corner portion on the other side to be bent. As described above, according to the present invention, by performing round chamfering on the airflow deflecting plate, generation of wind noise at the airflow deflecting plate can be prevented, and noise from the opening can be reduced.

[0013] In addition, the outlet device according to the present invention is provided with a bent hole portion, which is formed as necessary, in a bent portion of the airflow deflector plate in accordance with a bent curve. As described above, according to the present invention, since the bent portion of the airflow deflector is cut off, a strong force is not required at the time of bending, and a correct position without bending at an erroneous portion is obtained. Therefore, the bending process can be performed reliably, and workability and manufacturability can be improved.

 (One Embodiment of the Present Invention) Hereinafter, an outlet device according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. 1 is a schematic configuration diagram of the outlet device according to the present embodiment, FIG. 2 is an explanatory view of a vertical outlet state of the outlet device according to the present embodiment, and FIG. 3 is an outlet device according to the present embodiment. FIG. 4 is a schematic diagram of the main part of the installation, and FIG. 4 is an explanatory view of a blowing pattern of oblique blowing of the blow-out device according to the present embodiment.

As shown in the drawings, the outlet device 1 according to the present embodiment has a cylindrical net portion 2a and a rectangular outer cone portion 2b formed in an expanded shape on the indoor outlet side. An opening frame 2; a middle cone 3 as an airflow guide disposed inside the opening area of the opening frame 2 and formed in a rectangular shape expanding toward the indoor blowing side; An airflow deflector plate 4 disposed on the outer surface of each of the members, a rod-shaped support member 5 disposed integrally with the middle cone 3, and a cap 6 rotatably mounted on the tip of the support member 5. And a holder 7 mounted on the inner side surface of the opening frame 2 and holding the middle cone 3 at a predetermined position by fitting the cap 6, and a drift upstream of the middle cone 3 inside the opening frame 2. It is arranged as a plate, and the diameter is enlarged or reduced at the center of the airflow passage, and the opening area on the outer peripheral side is And a well-known circle shutter 8 for adjusting the distance.

The opening frame 2 is formed by inclining the outer cone portion 2b of the expanded shape at an angle of 37 ° with respect to the opening surface and inclining the outer cone portion 2b with respect to the opening surface. A vertically extending edge 2c is formed, and holders 7 are disposed at four places on the inner wall, respectively, and the neck 2a is connected to the duct 51 in the ceiling 50 to form a conditioned air. This is configured to take in air and blow it out of the room through the indoor opening.

The airflow deflecting plate 4 sets a bent curve on a steel plate of a predetermined size, and one side of the bent surface is fixed along the outer surface of the middle cone 3, and the other side is fixed to the one side. The angle is adjusted so as to be adjustable, and the inclined portion is formed. In the bent portion of the airflow deflecting plate 4, a bent hole portion 4a is formed by punching in accordance with a bending curve so as to be easily bent. Further, the corners of the airflow deflector 4 are rounded to prevent noise such as wind noise.

The support member 5 is formed in a substantially rod shape, is arranged in a cross shape above the middle cone 3, and is disposed integrally with the middle cone 3 with its tip protruding outside the middle cone 3. This is the configuration that is used.

The cap 6 is rotatably disposed at the tip of the support member 5, and the difference in distance between two fitted portions 6 a and 6 b having the same shape from the center of rotation is an opening frame. 2 are formed at unequal distances from the center of rotation so as to have the same length as the height 2c of the edge 2c. It has a symmetrical cocoon-shaped cross section.

The holder 7 receives the fitted portions 6 a and 6 b of the cap 6 and supports it from below, and the open upper end is removably fitted into the constricted portion 6 c of the cap 6 with elastic force. 6 is formed in a shape sandwiching both sides. The lower end of the middle cone 3 is substantially the same as the lower end of the opening frame 2 when the fitted portion 6 a having a smaller distance from the center of rotation of the cap 6 is fitted to the holder 7. When the fitted portion 6b having a larger distance from the center of rotation of the cap 6 is fitted to the holder 7, the height raised from the above-described position by the height of the edge 2c. It is disposed at a predetermined position on the inner side wall of the opening frame 2 so as to be located at the position.

Next, a blow-out pattern adjusting operation and a blow-out state in the blow-out device based on the above configuration will be described. First, the direction of the cap 6 engaged with the holder 7 is adjusted, and in the case of horizontal blowing and oblique blowing, the fitted portion 6a is positioned on the lower side, and both the opening frame 2 and the middle cone 3 are positioned. The lower ends are almost aligned, and in the case of vertical blowing, the fitted portion 6b is positioned on the lower side, and the lower end of the middle cone 3 is raised by the height of the edge 2c of the opening frame 2. To

When the conditioned air is sent from the duct 51 to the neck 2 a of the opening frame 2, the airflow is guided toward the outer periphery of the gas passage by the circle shutter 8 in the opening frame 2, and the outer cone 2 b and the middle portion are formed. It reaches between cone 3. By increasing the inclination of the outer cone portion 2b, the airflow path between the outer cone portion 2b and the middle cone 3 is widened, so that the airflow speed is not increased and noise generation is reduced.

In the case of horizontal blowing during cooling or the like, the conditioned air gradually flows sideways along the middle cone 3 and blows out horizontally into the room as it is because the airflow deflector 4 is not bent. The airflow attracts the air in the room, and an induced airflow is generated. In particular, in the case of cooling, in addition to blowing out cold air that is heavier than indoor air laterally and sufficiently diffusing it from the ceiling 50 to reach the living area, the cool air attracts air near the relatively warm ceiling 50. As a result, the cooling effect of indoor air can be enhanced.

On the other hand, in a vertical blowout during heating or the like, the conditioned air gradually flows sideways along the middle cone 3, but a horizontal airflow that has left the middle cone 3 causes the edge 2 below the outer cone 2 b to be lower. It blows down into the room by changing the direction of the flow on c. Downward airflow in the room induces air in the room, creating an induced airflow. In particular, in the case of heating, warm air, which is lighter than the room air, can be blown downward from the ceiling 50 to reliably reach the living area, and the warm air attracts and mixes the cooler room air. Therefore, the conduction of heat to the indoor air is promoted, and the effect of raising the temperature of the indoor air is great.

In the case of oblique blowing, the direction of air blowing is changed by adjusting the inclination angle of the airflow deflector 4 provided on the middle cone 3. When the airflow deflector 4 is set up at a bending angle of about 90 °, the airflow is interrupted by the airflow deflector 4 and flows to the left and right sides on the middle cone 3. By blowing out, as shown by the solid line in FIG. 4, the air can be blown into the room with a spread in a direction inclined obliquely downward from the ceiling surface. When the bending angle of the airflow deflector 4 is reduced, an airflow blown out along the middle cone 3 is generated as it is, and the airflow is deflected and combined with the airflow blown out from the corner, so that the airflow is slightly obliquely downward in each direction around the outlet. Will be blown out. In a state where the airflow deflector 4 is not bent at all, all the airflow blows out along the middle cone 3 in the horizontal direction as in the case of the horizontal blowout. In particular, in the case of cooling, by raising the airflow deflector 4 and blowing the cool air obliquely downward from the ceiling 50, the reaching distance of the blown airflow below becomes short, and the draft in the living area becomes hard to feel. On the other hand, the air current diffuses in the horizontal direction and attracts and mixes the air in the room, so that the reach of the cool air in the room expands conversely, and cooling can be performed efficiently with almost no dead zone. It will be. In addition, since the air is blown obliquely downward, the amount of indoor air attracted to the vicinity of the ceiling is small, and the ceiling surface is not easily polluted by dirty indoor air. Furthermore, even if the suction port is arranged near the system ceiling as shown in FIG. 4, since the air is blown out from the corner, the short circuit amount due to the ceiling suction is small.

As described above, in the air outlet device according to the present embodiment, the horizontal flow and the vertical flow are switched by adjusting the position of the entire middle cone 3, and the air flow is controlled by adjusting the inclination angle of the air flow deflector 4. The amount of air blown from the corner can be adjusted, the degree of oblique air blow can be changed freely, and the optimum blow pattern can be easily obtained according to the installation location and the condition of air conditioning.

In the outlet device according to the above-described embodiment, the middle cone 3 is provided as an airflow guide in the opening area of the opening frame 2. As shown in FIG. 5, a middle pan 9 may be provided as an airflow guide as an outlet, and the airflow deflector 4 may be provided on the upper surface of the middle pan 9.

In the outlet device according to the embodiment, the airflow deflector 4 is made of a steel plate. However, the airflow deflector 4 is deformed in accordance with the temperature of the airflow, and the temperature of the airflow is reduced. When the temperature is about 17 ° C. or less, the sheet does not bend at all and follows the surface of the middle cone 3, and when the temperature of the air stream is about 25 ° C. or more, it stands at a bending angle of about 90 °. The blowing direction is automatically switched according to a change in the temperature of the airflow, so that the switching operation is not required and labor can be saved. In addition, an end of an auxiliary plate made of a shape memory alloy is fixed to one side and the other side of the airflow deflection plate 4 on both sides of the bent curve, and the airflow deflection plate 4 is deformed according to the temperature of the airflow. It is also possible to make the other side stand up or fall down, the blowing direction is automatically switched according to the temperature change of the airflow as in the former case, saving power and reducing the amount of shape memory alloy used. Lower costs can be achieved.

In the outlet device according to the above-described embodiment, the horizontal, vertical, and oblique air outlets are switched. However, in addition to the above, the cap 6 can be fitted similarly to the vertical air outlet. The joining portion 6b is located on the lower side, and the airflow deflector 4 is further raised with respect to the middle cone 3 from the state where the lower end of the middle cone 3 is raised by the height of the edge 2c of the opening frame 2. In this blowout, the airflow is blocked by the airflow deflecting plate 4 and flows to the left and right on the middle cone 3, and from the corner where the airflow deflecting plate 4 is not provided. By blowing out along the edge 2c, as shown by the broken line in FIG. 4, the airflow spreads obliquely downward into the room and blows downward. Especially in the case of heating, the downward airflow spreads out into the living area. Achieving drafts even at high airflows It can be difficult to repel.

[Effect of the invention]

 As described above, in the present invention, the position of the airflow guide with respect to the opening frame and the bending angle of the other side of the airflow deflector are adjusted to change the direction of airflow and to provide various airflow patterns. As a result, the air conditioning performance can be enhanced, and the adjustment of the blowing direction can be easily performed without complicated operation, and the handling efficiency is excellent. In addition, in the present invention, the airflow deflector automatically rises or falls down in response to a change in the temperature of the airflow to change the blowout pattern, so that the adjustment of the blowout direction by the operator is almost unnecessary, and the work is not required. This has the effect of significantly reducing labor. In addition, in the present invention, the airflow deflector is moved by the auxiliary plate to automatically change the airflow pattern according to the airflow temperature. This has the effect of saving energy and reducing the cost by suppressing the use of shape memory alloys. In addition, in the present invention, by adjusting the angle of the outer cone part, the distance between the outer cone part and the airflow guide part is widened, the airflow speed is suppressed, and noise such as wind noise can be greatly reduced. At the same time, there is an effect that the airflow guiding performance is improved and corner blowing can be reliably performed. In addition, in the present invention, by performing round chamfering on the airflow deflecting plate, there is an effect that generation of wind noise at the airflow deflecting plate can be prevented and noise from the opening can be reduced. In addition, in the present invention, since the bent portion of the airflow deflector is cut off, a strong force is not required at the time of bending, and the bent portion of the airflow deflector does not bend at an incorrect position and is at a correct position. This has the effect that bending can be performed reliably and workability and manufacturability can be improved.
