Description

  The present invention relates to an air outlet device arranged to face an air-conditioning target space, and more particularly, to an air outlet device capable of adjusting an air outlet direction with a simple wind direction variable mechanism.

  In air conditioning equipment, blowout devices that blow out conditioned air sent through a duct into an indoor space as an air-conditioning target space generally have a blowout direction variable in addition to a fixed blowout direction. Is used. As a mechanism for changing the blowing direction in such an outlet device, there is a mechanism that changes the angle of a vane-shaped vane that guides the airflow inside the outlet device, or a mechanism that adjusts the blowing direction by adjusting other movable guide parts. is there. As an example of such an outlet apparatus, there is one described in registered utility model publication No. 3059441, which is shown in FIG. FIG. 6 is a schematic cross-sectional view of a conventional air outlet device.

  In FIG. 6, the conventional air outlet device 100 includes a substantially rectangular cylindrical opening frame 101 that is arranged on a ceiling or a wall and is supplied with conditioned air from a duct 51, and an opening area length of the opening frame 101. A plurality of substantially flat plate-like blades 102 arranged at predetermined intervals in parallel to the side direction and end-supported so as to be tiltable to the opening frame body, and predetermined in the vertical direction on the inner peripheral surface of the opening frame body 101 A movable member 103 that is movably attached within a range, is connected to the end of the blade 102 and tilts the blade 102 at a predetermined angle, and is disposed between the movable member 103 and the opening frame body 101, The temperature sensor 104 expands and contracts depending on the temperature, and a spring 105 that biases the movable member 103 in a predetermined direction with respect to the opening frame 101.

  The movable member 103 moves with respect to the opening frame body 101 due to a change in the amount of protrusion of the temperature sensor 104 accompanying a change in the temperature of the conditioned air, and the blade 102 is tilted. It is guided by the blades 102, proceeds in the same direction as the blades 102 from the front direction of the opening while changing the traveling direction, and blows out into the room.

  FIG. 7 shows an example of a structure including a movable guide mechanism different from the above example as another conventional air outlet device. FIG. 7 is a schematic sectional view of another conventional outlet device.

In FIG. 7, another conventional outlet device 200 has a configuration in which a pair of guide members 202 having an L-shaped cross-section are attached to the side portions in the outlet body 201 so as to be movable up and down and to hold their positions. In this mechanism, the airflow is deflected by changing the vertical positions of the guide members 202, and the airflow direction can be changed from the front direction of the opening of the air outlet main body 201 as necessary.
Registered Utility Model No. 3045941

  The conventional air outlet device is configured as described above, and in the case of the former former described in Patent Document 1, it is excellent in the guidance performance of the air flow, and can control the air direction by reliably guiding the indoor air. The link mechanism including the movable member 103 that interlocks and tilts the plurality of blades 102 is complicated and has a problem that the cost is increased.

  In the latter case, the guide member 202 can be moved up and down inside the outlet body 201 so that the wind direction can be adjusted, while the L-shaped cross-sectional member position is not moved after the adjustment. Each of the mechanisms to be realized has a problem that the cost becomes high.

  Furthermore, in each of these conventional air outlet devices, each member that guides and deflects the airflow has a certain length in the airflow inflow direction from the upstream side that coincides with the front direction of the indoor opening of the air outlet device and is movable. Therefore, the wind direction adjusting mechanism portion needs to be at least larger than the movable range of these airflow deflecting members, and not only occupies a large space in the air outlet device, but also the size of the air outlet device as a whole. Also had the problem of affecting.

  The present invention has been made to solve the above-described problems, and the mechanism portion for guiding and deflecting the airflow can be appropriately adjusted in the airflow blowing direction while being extremely compact in the airflow inflow direction. An object of the present invention is to provide a blowout device that can be downsized as a whole and can be reduced in cost with a simple structure.

  An air outlet apparatus according to the present invention includes at least a substantially box-shaped air outlet body having one opening portion to which gas for air conditioning is supplied and another opening portion for directing the gas toward the air conditioning target space. The air outlet apparatus in which the one opening portion and the other opening portion are respectively arranged on two mutually opposing surfaces of the air outlet body, and the air conditioning gas flows into the one opening portion from the front of the opening. The air outlet body is formed of a substantially rectangular box-shaped body made of a substantially thin plate, and a plurality of holes are drilled at a predetermined pitch in the long side direction of the surface as the one opening portion. Formed by a substantially thin plate-like body having a plurality of holes formed in substantially the same shape and arrangement as the holes on one surface of the outlet body, and is slidable within a predetermined range along the one surface. Slide plate and the slide plate, the outlet The position is changed from a fully open state position where the holes and the holes on the body side overlap each other to a position shifted by 1/4 to 3/4 of the hole opening dimension in the multiple array direction of the holes in the multiple array direction of the holes. Degree adjusting means.

  As described above, according to the present invention, the slide plate having a plurality of holes is slidably disposed along one surface of the air-conditioning gas inflow side where the plurality of holes are also formed in the outlet body. The slide plate is moved to a predetermined dimension relative to the outlet body to shift the holes of the outlet body and the holes of the slide plate, thereby reducing the net opening area in the front direction of each hole and sliding. By forming a stepped part consisting of each hole and its edge on the entire surface of the outlet body below the hole in the vicinity of each hole in the plate, the flow path is narrowed by reducing the hole opening area, and the speed when passing through the hole Because of the nature of the fluid that is going to flow along the stepped part on the lower side of the slide plate, the airflow that has increased is bent obliquely toward the side with the stepped part, and the airflow changes from the front of the hole to the oblique direction. Let it go into the air outlet body and tilt it into the target air conditioning space It is possible to blow out the air-conditioning gas to the air-conditioning target space by changing the blowing direction with a very simple mechanism that simply slides the slide plate over the entire surface of the air outlet body. The cost of the apparatus can be reduced, and the size of the airflow direction adjusting mechanism in the airflow inflow direction can be remarkably reduced to a thickness of about two thin plates, and the air outlet main body can be greatly reduced in size by saving space. .

  Moreover, the blower outlet apparatus which concerns on this invention is a substantially box-shaped blower outlet main body which has one opening part supplied with the gas for air conditioning, and the other opening part which directs the said gas to the air conditioning object space side. And the one opening part and the other opening part are respectively disposed on two mutually opposing surfaces of the outlet body, and the air conditioning gas flows into the one opening part from the front of the opening. In the outlet device, the outlet body is formed of a substantially cylindrical box-shaped body made of a substantially thin plate, and the plurality of holes are formed on a substantially planar surface as a predetermined pitch on the circumference of a predetermined diameter. And is formed by a substantially thin plate-like body having a plurality of holes formed in substantially the same shape and arrangement as the holes on the one surface, and the center position of each hole arrangement is the position of the hole arrangement on the one surface. Align the center point and rotate the center position of each hole arrangement The slide plate is disposed so as to be able to rotate and slide within a predetermined range along the one surface as a center, and the slide plate is opened from the fully open state position where the holes overlap with the holes on the outlet body side. And an opening degree adjusting means for changing the position up to a position shifted in the rotation direction by 1/4 to 3/4 of the angle.

  As described above, according to the present invention, the slide plate having a plurality of holes formed therein can be slidably rotated along one surface of the air conditioning gas inflow side in which the plurality of holes are formed in the outlet body. Disposing and sliding the slide plate by a predetermined angle with respect to the air outlet body to shift each hole of the air outlet body and each hole of the slide plate, reducing the net opening area in the hole front direction of each hole, By creating a stepped part consisting of each hole and its edge on the entire surface of the air outlet body on the lower side in the vicinity of each hole of the slide plate, the flow path is narrowed by reducing the hole opening area, and when passing through the hole Due to the nature of the fluid that tends to flow along the stepped part on the lower side of the slide plate, the increased airflow will bend and advance diagonally to the side where the stepped part is located. Change the air flow into the outlet body, and the airflow from each hole A structure that can be blown out into the air conditioning target space in a state where it is combined as a swirling flow in the air outlet body, and that sends out air conditioning gas to the air conditioning target space while changing the air blowing state. It can be realized with an extremely simple mechanism that simply rotates the stacked slide plates, and the cost of the device can be reduced, and the size of the wind direction adjusting mechanism in the air flow inflow direction can be reduced to a thickness of about two thin plates. It is possible to reduce the size of the air outlet body by saving space.

  In addition, the blowout device according to the present invention has a plurality of arrangements of holes in the one side of the blowout body and the surface of the blowout body, and the thickness of each of the slide plates as needed. 1/30 or more of the maximum opening width in the direction.

  As described above, according to the present invention, the thickness of the one surface portion of the air outlet body and the slide plate is formed in an appropriate size range with respect to each hole, and an appropriate step is formed on the stepped portion generated below the slide plate. By giving it closer to the slope, reducing the opening area and increasing the speed and making the airflow coming out of the hole easy to follow this stepped part, the state of tilting the traveling direction of the airflow can be obtained more easily, The deflecting performance of the airflow in the oblique direction can be optimized, and even if the blown airflow is small, the airflow can be reliably switched between the front direction of the opening and the oblique direction, and the airflow blowing direction can be reliably controlled.

  In addition, the air outlet device according to the present invention is a predetermined elastically deformable substantially sheet in which a plurality of holes are formed between the air outlet body and the slide plate in the same manner as one surface of the air outlet body, if necessary. An intermediate layer made of a material is interposed.

  As described above, according to the present invention, the intermediate layer is disposed between the outlet body and the slide plate, and the stepped portion side generated on the lower side of the slide plate is increased by increasing the step near the hole by the thickness of the intermediate layer. The airflow is easier to bend and travel, and the airflow deflection performance is improved. In addition, the air outlet and the slide plate can be in close contact with each other to ensure airtightness, and adverse effects on the wind direction control due to the flow of gas between the air outlet body and the slide plate can be prevented, and an oblique blow-out state can be reliably obtained. .

  Hereinafter, an air outlet apparatus according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a front view, a bottom view, and a right side view of an air outlet device according to the present embodiment, and FIG. 2 is a perspective view of the air outlet device according to the present embodiment and a slide plate operation state explanatory diagram.

  In each of the drawings, the air outlet device 1 according to the present embodiment is provided with one opening portion to which conditioned air as air conditioning gas is supplied and another opening for directing the conditioned air toward the indoor space to be air conditioned. A substantially rectangular box-shaped air outlet body 10 having a portion, a substantially plate-like slide plate 15 slidably disposed along a part of the outer surface of the air outlet body 10, and the slide plate 15 It is a structure provided with the actuator 18 as an opening degree adjustment means to slide with respect to the exit main body 10 and to change a position.

  The outlet body 10 is formed of a substantially rectangular box-shaped body made of a thin plate, and as the one opening portion, rectangular holes 11 are formed on one plane in two rows in the long side direction of the one plane at a predetermined pitch. A plurality of perforations are arranged, and the other opening facing the one surface is opened, and the one surface is connected to the opening of the chamber portion 40 for supplying conditioned air. The conditioned air supplied through the chamber unit 40 is blown out from the other side opening facing the indoor space to the indoor space. More specifically, the thickness of the thin plate forming one surface of the outlet body 10 is preferably 1 mm, and the opening dimension of each hole in the one surface is preferably 20 mm.

  An intermediate layer 12 made of a flocked sheet having a plurality of holes 12a having the same shape and arrangement as the outlet main body 10 is integrally disposed at one end of the outlet main body 10, and the slide plate 15 is provided with the intermediate layer 12. It will be in a state of touching. The intermediate layer 12 eliminates the gap between the slide plate 15 and the blower outlet body 10 to improve airtightness, and the sliding resistance of the slide plate 15 is reduced by bringing the flocking side into contact with the slide plate 15. Since the slide plate 15 can be moved smoothly, the load on the actuator 18 can be reduced. The thickness of the intermediate layer 12 is preferably 1 mm.

  On the other hand, on the other surface side facing the indoor space of the air outlet body 10, a vane plate 13 as an air flow guide means similar to the conventional one is disposed. The vane plate 13 is a rectangular thin plate-like member that appears as an indoor side portion of the air outlet device 1, and is fixed to the air outlet body 10 with the longitudinal direction parallel to the long side direction of the air outlet body 10, and the conditioned airflow is In addition to guiding the blower body 10 to be uniformly blown in the short side direction, the interior of the blower body 10 including the hole 11 is difficult to see from the indoor side to further improve the aesthetics. Yes.

  The chamber portion 40 to which the outlet body 10 is connected is formed in a substantially box-like body surrounding an opening region having a substantially rectangular cross-sectional shape, and a side opening in the ceiling 50 is connected to the duct 51 so as to be closer to the indoor space. The blower outlet body 10 is connected to the lower opening, and the conditioned air is supplied from the duct 51 and the conditioned air is sent to the blower outlet body 10 side.

  The slide plate 15 is formed as a rectangular thin plate that is slightly shorter in the long side direction than one surface of the outlet body 10, and has a plurality of holes 16 having substantially the same shape and arrangement as the holes 11 on one surface of the outlet body 10. It is the structure which is slidably arrange | positioned along the one surface of the blower outlet main body 10 in the surface long side direction. More specifically, the thickness of the slide plate 15 is 1.6 mm, and the opening width in the hole arrangement direction of each hole 16 is about 85% (17 mm) of the opening width of the holes 11 of the outlet body 10. It is preferable to do this. Only the slide plate 15 is positioned in the conditioned air flow path composed of the chamber portion 40 and the outlet body 10 as a wind direction adjusting mechanism portion, and the actuator 18 for driving the slide plate 15 can be positioned outside the flow path. Since it can do, the space of the wind direction adjustment mechanism part in a flow path can be suppressed very small.

  The actuator 18 is disposed at one end of the outlet body 10 and has a movable portion connected to the end of the slide plate 15 side. The slide plate 15 is connected to the hole 11 on the outlet body 10 side. This is a mechanism for changing the position from the overlapped fully open position to a position shifted in the multiple array direction of the holes 16 by 1/4 to 3/4 of the hole opening dimension in the multiple array direction of the holes 16. The preferred position adjustment of the slide plate 15 by the actuator 18 includes a fully open state in which the holes 11 and 16 are overlapped with the center positions in the hole arrangement direction being overlapped, and a long side direction in which the slide plate 15 is coincident with the hole arrangement direction from this state. This is a case of switching to a state in which the net opening width of the hole as viewed from the front direction of the hole is 8 mm after sliding to 10.5 mm. Note that the movable mechanism itself of the actuator 18 is well known, and detailed description thereof is omitted.

  Next, the air flow blowing direction variable operation in the air outlet device based on the above configuration will be described. The conditioned air sent from the duct 51 enters the chamber portion 40 sideways, and the airflow of the conditioned air turns downward in the chamber portion 40 so that the airflow inflow direction with respect to the outlet body 10 coincides with the front direction of the hole. Toward the outlet body 10.

  When the airflow flows into the outlet body 10, the airflow passes through each hole 16 of the slide plate 15 and each hole 11 on one surface of the outlet body 10, but the direction of the airflow traveling through the outlet body 10 depends on the position of the slide plate 15. It depends on. That is, in the fully open state in which the holes 11 and 16 of the air outlet body 10 and the slide plate 15 overlap each other vertically (see FIG. 2B), the airflow is perpendicular to the surface of the slide plate 15 and the entire surface of the air outlet body 10. The traveling in the direction is maintained as it is, and the vehicle travels straight and passes through the holes 11 and 16 and proceeds downward in the outlet body 10 as it is.

  On the other hand, from the fully opened state, the actuator 18 is used to move the slide plate 15 to one end side in the long side direction 1/4 to 3/4, preferably 1/2 to 3/4, more specifically 1/2 to 3/4. Is slid by 10.5 mm, and the holes 11 and 16 of the outlet body 10 and the slide plate 15 are laterally displaced from each other, and the net opening area of the hole viewed from the front direction of the hole is reduced (FIG. 2 ( C)), a stepped portion 19 is formed on the lower side of the slide plate 15 in the vicinity of the holes 16.

  The air flow, which has been narrowed by the reduction of the opening area of the hole and increased in velocity when passing through the hole, flows along the stepped portion 19 below the slide plate 15 located as the trailing edge of the hole. Due to the nature, the air travels obliquely toward the side where the stepped portion 19 is present, and a state in which the airflow is changed from the hole front direction to the oblique direction is obtained. In this manner, the airflow is inclined and flows toward the other end in the long side opposite to the side where the slide plate 15 is moved inside the outlet body 10, and is inclined from the outlet body 10 to the indoor space. To blow out.

  If the position of the slide plate 15 is changed in this way, the direction in which the conditioned air is blown out can be switched appropriately between a vertically downward direction and a diagonally downward direction, and a more appropriate blowing state can be selected according to the air condition of the indoor space. The air conditioning effect can be enhanced.

  As described above, in the air outlet device according to the present embodiment, the slide plate 15 in which the plurality of holes 16 are formed is used as one surface of the conditioned air inflow side in which the plurality of holes 11 in the air outlet body 10 are similarly formed. When the slide plate 15 is displaced with respect to the outlet body 10 and the holes 11 and 16 are shifted laterally, the net of the holes 11 and 16 in the front direction of the holes is arranged. In addition to reducing the opening area of the slide plate 15 and forming the stepped portion 19 composed of the holes 11 and the edges of the outlet body 10 below the vicinity of the holes 16 of the slide plate 15, when passing through the holes, Due to the nature of the airflow itself, the airflow whose speed has been increased by narrowing the flow path will bend and advance toward the side where the stepped portion 19 is located, and the airflow is changed from the front of the hole to the oblique direction to blow. Proceed into the exit body 10 and directly into the indoor space Can be blown out, and a mechanism for changing the blowing direction of the conditioned air to the indoor space and sending it out can be realized with a very simple mechanism that simply slides the slide plate 15 superimposed on the entire surface of the outlet body 10, The cost of the apparatus can be reduced.

  In addition, in the blower outlet apparatus which concerns on the said embodiment, although the rectangular box-shaped blower outlet main body 10 is used and it is set as the structure which moves the slide plate 15 of the upper side linearly, it shows in FIG. As described above, the outlet body 20 is a substantially cylindrical box-shaped body made of a substantially thin plate, and a large number of holes 21 are formed on one end surface of the plane so as to be drilled and arranged at a predetermined angular pitch on the circumference of a predetermined diameter. On the other hand, the slide plate 25 having the same hole shape and arrangement as that of the one end face is disposed so as to be slidable by a predetermined range along the one end face with the center of the hole 26 as the center of rotation. By adjustment, the positions of the holes 21 and 26 of the air outlet main body 20 and the slide plate 25 from the fully open position where the holes overlap each other to a position shifted in the rotation direction by 1/4 to 3/4 of each hole opening angle. And move the holes 21 and 26 forward from each other. Similarly, it is also possible to adopt a configuration in which the air flow is tilted obliquely from the front direction of the hole and is blown out. In addition to the original blowout in the front direction of each hole, each slide plate 25 is displaced and arranged on the circumference. By synthesizing the airflow traveling obliquely from the hole, it can be blown into the indoor space as a swirling flow, and the air conditioning effect is excellent when the floor outlet is used.

  In the press device according to the above embodiment, the slide plate 15 is moved by the actuator 18, but the present invention is not limited to this, and the arrangement may be made at a location where frequent airflow adjustment is not required. In some cases, a manual operation mechanism may be provided as an opening adjustment means for sliding the slide plate 15 so that the operator can manually adjust the position of the slide plate 15 from below the outlet. The position adjustment of the slide plate 15 located in the ceiling 50 can be performed without requiring a power source or the like, and the cost can be reduced.

  Further, in the press device according to the above-described embodiment, the air outlet is provided at the opening edge portion on the opposite side to the direction in which the hole 11 of the air outlet body 10 is in the sliding direction of the slide plate 15 and deflects the airflow. A thin piece made of the same material as that of the main body 10 or another flexible material may be disposed in a state where the thin piece is obliquely projected into the opening range of the hole 11, and the change in the airflow traveling direction in the oblique direction is further improved. Can be urged.

  The blowout state in two situations where the position of the slide plate is changed using the blowout device according to the present invention will be examined, and the evaluation results comparing the airflow blowout directions in each situation will be described.

  First, the conditioned air blowing state was evaluated when the slide plate was in the fully open state where the holes of the slide plate were completely overlapped with the holes on one side of the outlet body. The main dimensions of the air outlet device are: the opening width of the hole on the air outlet main body side is 20 mm, the thickness of one surface portion with this hole is 2 mm including the intermediate layer, the opening width of each hole of the slide plate is 17 mm, the slide plate Is 1.6 mm, and the arrangement pitch of the holes of the outlet body and the slide plate has the same value. In this case, with respect to the air flow blown from the air outlet device, the wind speed is measured at each of a plurality of measurement points set in a grid pattern every 20 cm in the hole arrangement direction and downward with respect to the air outlet lower surface center point, and the wind speed distribution is determined. Obtained. The measurement conditions are a supply air volume of 168 CMH, a blowing temperature of 40.3 ° C., and an indoor temperature of 20.0 ° C. Table 1 shows the value of the wind speed (m / s) at each measurement point, and FIG. 4 shows a graph in which the wind speed distribution is visualized by connecting portions of equal wind speed with lines.

  When looking at the wind speed distribution in FIG. 4, there is a region where the wind speed is greatest immediately below the air outlet, and a region of equal wind speed extends directly below the air outlet, so that the airflow is blown out from the air outlet as it is. Is appearing. In the air outlet device of the present invention, when each hole on the one surface side of the air outlet main body is in a fully opened state, it was confirmed that the air flow went straight as it was and was blown downward into the indoor space.

  Subsequently, for the same air outlet device, the slide plate is shifted from the fully open state in the hole arrangement direction, and the overlap between the holes of the slide plate and the air outlet body is shifted so that the net opening width of the hole viewed from the hole front direction is 8 mm. In this case, the conditioned air blowing state was evaluated. In the same manner as described above, the wind speed was measured at each of a plurality of measurement points for the air flow blown out from the outlet device, and the wind speed distribution was obtained. The measurement conditions are a supply air volume of 168 CMH, a blowing temperature of 41.5 ° C., and an indoor temperature of 20.5 ° C. Table 2 shows the value of the wind speed (m / s) at each measurement point, and FIG. 5 shows a graph in which the wind speed distribution is visualized by connecting portions of equal wind speed with lines.

  When the wind speed distribution in FIG. 5 is seen, as in the case described above, although there is a region where the wind speed is greatest immediately below the outlet, the constant wind speed region extends obliquely downward from the outlet and further away. A state of being blown obliquely downward appears. In the air outlet device of the present invention, when the slide plate is moved by a predetermined dimension and each hole on the one side of the air outlet main body is set to a predetermined opening state, it is confirmed that the air current is blown obliquely downward into the indoor space. did it.

  As described above, the air outlet device according to the present invention can reliably switch between the downward air blowing and the oblique downward air blowing by appropriately changing the position of the slide plate, and the air outlet according to the air conditioning situation similar to the conventional air outlet. It was confirmed that switching of the state could be realized by simply sliding the slide plate, and an excellent wind direction adjustment function was obtained with an extremely simple mechanism.
