Description

  The present invention relates to a blowout device that blows conditioned air into an air-conditioning target space to perform air conditioning.

  When air conditioning is performed on an indoor space such as an office space in a building, the air outlet that blows conditioned air into the indoor space subject to air conditioning is a ceiling that takes into account the ease of conditioned air reaching the indoor space. It is common to arrange | position to. And when performing air conditioning with respect to such a comparatively large indoor space, control of dampers, such as VAV provided in the system which connected an air conditioner and a plurality of outlets via a duct, A mechanism for adjusting the temperature of the indoor space to an appropriate temperature by adjusting the amount of air blown out is adopted. An example of such a conventional air conditioning system is disclosed in Japanese Patent Laid-Open No. 8-75231.

  In such a conventional air conditioning system, an air outlet device such as a multi-layer cone type or a pan type that is generally excellent in diffusibility of the conditioned air into the space is used for the air outlet of the ceiling. However, a system such as Japanese Utility Model Laid-Open No. 5-18944 has been proposed in order to meet the needs that cannot be handled by a system that employs only such an outlet device.

JP-A-8-75231 Japanese Utility Model Publication No. 5-18944

  In the air conditioning according to the conventional system as disclosed in Patent Document 1, it is common that the air outlet provided on the ceiling is in a state where the draft does not occur in the living area. In recent years, the difference between the indoor temperature and the outside air temperature obtained by air conditioning tends to be reduced from the viewpoint of energy consumption suppression. In such an air condition, when the outside air temperature is extremely high or low, a person can enter the indoor space from the outside and feel the cold feeling that comes in contact with the indoor air from the state accustomed to the outside air temperature. I often feel unsatisfactory in the sense of warmth.

  However, in a system that covers the entire room using a conventional air outlet that emphasizes diffusibility, in order to satisfy the feeling of cooling and warmth experienced by some people, Air conditioning could not be performed, and the air conditioning state of the entire indoor space had to be adjusted. Adjustment of the air-conditioning condition of the entire indoor space takes time to reach the indoor temperature expected by the user who wants to change the temperature. As a result, the temperature may be uncomfortable, and it is difficult to take an appropriate measure, and the amount of energy input to the air conditioning increases as the entire space is adjusted.

  On the other hand, if air outlets that can adjust the wind direction and have excellent directivity of the blown airflow, such as nozzle type and pan-carver type, are used for local air conditioning to the user, the temperature in the surrounding area of the user will be increased by the conditioned air. Effective air-conditioning can be expected, for example, by making it easier to cause changes and shortening the time required to reach the user's preferred temperature.

  And the system which improved the adaptability to the preference of each person's temperature using together such a strong directivity blower outlet and the blower outlet for temperature-controlling the whole indoor space uniformly is the said patent document. Conventionally, as shown in FIG. However, in this conventional system, two types of air outlets are connected to the air supply system from the air conditioner that generates conditioned air. Of these, the more directional air outlets are located in the living area when not in use. Since the air volume may be reduced so as not to give a draft, there is a problem that the air volume balance of the entire air supply system is likely to be lost and problems such as instability of blowing at other outlets occur.

  The present invention has been made in order to solve the above-mentioned problems, and adjusts the air volume of a local blow-out without affecting the supply of conditioned air while simultaneously using a blow-out intended for a wide area and a local blow-out. It is possible to operate the air-conditioning system without difficulty, and while maintaining the air-conditioning condition of the entire air-conditioning target space, it is possible to quickly shift the user's sensible temperature to a comfortable state by utilizing the local blowout. It aims at providing the blower outlet apparatus which can perform air conditioning well.

  An air outlet apparatus according to the present invention is an air outlet apparatus that is disposed on a ceiling facing an air conditioning target space, is connected to a duct in the ceiling, and blows conditioned air supplied from the duct to the air conditioning target space. A blower outlet body that is formed as a substantially box-like body surrounding the opening through which the conditioned air passes, is disposed at a predetermined position on the ceiling, and is connected to the duct to introduce the conditioned air into the opening; The inner side has a substantially cylindrical part serving as an air passage, and is supported so that the orientation can be adjusted to a portion closer to the air-conditioning target space in the central portion of the opening of the outlet body, and the conditioned air flows into the air passage, One or a plurality of guide nozzles that guide and blow out conditioned air in the air passage extension direction, and are arranged at predetermined positions closer to the duct than the guide nozzles in the outlet body, and operate based on external control. , It has a fan for blowing air into only the air passage of the guide nozzle, and a substantially plate-like guide body arranged in one or more predetermined arrangements, and the side of the guide nozzle at the opening of the outlet body A plurality of airflow guide portions that are arranged in each of the guide bodies and cause the conditioned air to travel along each guide body and blow the conditioned air in a diffused state into the air-conditioning target space, and a connection between the duct inside the outlet body Shielding that is disposed at least between the portion and the conditioned air inflow portion of the blower fan, partitions the opening of the outlet body, and divides the conditioned air toward the blower fan and toward the airflow guide And a fan for switching the operating state and the non-operating state by control based on a user's operation.

  As described above, according to the present invention, the air flow guide portion that guides the air flow of the conditioned air in a plurality of directions is arranged in the opening portion of the predetermined opening cross section of the air outlet body, and the local blowout independent of the air flow guide portion is provided. A guide nozzle for air and a fan for blowing are arranged, and the air blowing guide is mainly operated in accordance with the operation of the fan for blowing, and the local blowing of conditioned air from the guide nozzle to a desired position and the non-operation of the fan for blowing. The conditioned air can be guided from the air outlet position to the air conditioning target space so that the air flow of the conditioned air can be widely diffused. In addition to being able to diffuse the conditioned air reliably over a wide area of the air-conditioning target space, it can be localized from the guide nozzle to a specific narrow area where the user exists, if necessary. Efficient air conditioning with a single outlet, such as blowing out and adjusting the temperature locally to the user's position in the living area while suppressing the effect on the entire space, making it possible to improve the user's temperature. This can reduce the cost of air conditioning. In addition, even when the blower fan is not activated and local blowout is not actively performed from the guide nozzle, the amount of air supplied to the blowout port can be maintained and the entire air conditioning system including the blowout port may be affected. Absent.

  In addition, the air outlet device according to the present invention opens and closes the shielding portion at least at a portion disposed between the duct connecting portion of the air outlet main body and the conditioned air inflow portion of the blower fan as necessary. One or a plurality of possible holes are provided, and one or a plurality of the holes are opened to allow the conditioned air to travel in the shortest distance from the duct side to the blower fan through the holes, and the holes are closed. The state of restricting the progress of conditioned air to the blower fan can be switched, and the blower fan operates in a state in which the shielding portion opens a hole and allows the progress of conditioned air, While the conditioned air is forced to flow into the guide nozzle, it is deactivated when the shielding portion closes the hole.

  As described above, according to the present invention, the conditioned air that has advanced from the duct into the outlet body is delivered from the duct through the hole of the shielding portion while the conditioned fan is blown out and the conditioned air is blown out from the guide nozzle. While maintaining the speed as much as possible, flow into the blower fan, operate the blower fan to add blast pressure to the conditioned air, and send the conditioned air to the guide nozzle to harmonize from the guide nozzle to the air conditioning target space. The user is in a comfortable state, for example, the air can be blown out strongly to reach the position of the user in the living area, and the user can directly feel the coolness or warmth from the airflow hitting the user's body. It is possible to obtain a powerful sensory temperature adjustment state that is shifted to an early stage. In the non-operating state of the fan, the conditioned air that has advanced from the duct to the outlet body is more likely to travel from the fan side to the airflow guide unit side. A state can be obtained in which the conditioned air is widely blown from the airflow guide unit to the air conditioning target space to uniformly adjust the temperature of the air conditioning target space.

  Further, in the air outlet device according to the present invention, if necessary, the shielding portion is formed in a substantially box shape, and is disposed inside the air outlet body so as to surround at least the guide nozzle and the air blowing fan. In the non-operating state of the fan, most of the conditioned air that has flowed into the outlet main body opening from the duct side is guided to the airflow guide unit side.

  As described above, according to the present invention, the guide nozzle and the blower fan are surrounded by the substantially box-shaped shielding portion, and the conditioned air introduced from the duct side is urged toward the airflow guide body side when the blower fan is not in operation. Therefore, in a situation where a state in which the air flow of the conditioned air is widely diffused mainly from the air flow guide unit is selected, the conditioned air can be smoothly introduced into the air flow guide unit, and the conditioned air is spread over a wide area of the air conditioning target space. While it can be diffused properly and efficiently, air conditioning can be performed efficiently, while the conditioned air reaches the guide nozzle and is not blown from the guide nozzle, and the conditioned air advances from the guide nozzle to the living area where the user exists. Can be reliably prevented, and drafts in the residential area can be avoided.

  Further, in the blowout device according to the present invention, if necessary, a plurality of opening holes may be provided in the portion where the shielding portion is disposed between the connection portion with the duct and the conditioned air inflow portion of the blower fan. At least two plate-like bodies to be drilled are arranged so as to be slidable with each other. When driven from the outside, one plate-like body is moved relative to the other so that the opening holes overlap with each other. The state where the conditioned air can pass through the hole and the state where the opening holes do not overlap each other and the conditioned air cannot pass through the opening hole can be switched.

  As described above, according to the present invention, the portion disposed between the connecting portion of the shielding portion with the duct of the outlet main body and the conditioned air inflow portion of the blower fan is provided with two plates with holes. When the shield is open, the conditioned air passes through the holes by sliding the plate-like bodies together to create an open state where the holes overlap and a closed state where the holes do not overlap. The air is blown from the guide nozzle via the fan, and in the closed state of the shielding part, the conditioned air moves sideways along the shielding part to reach the airflow guiding part, and is blown from the airflow guiding part. The switching of the blowing state is realized with a simple structure, and the switching reliability can be improved. Further, the portion where the two plate-like bodies in the shielding portion are overlapped can reduce the size in the thickness direction, and the outlet body that accommodates the portion has a compact structure in the direction parallel to the thickness direction. can do.

  Further, the air outlet device according to the present invention is separated from the air flow guide portion between the air outlet main body inner surface and the guide nozzle, if necessary, and communicates with the air inlet portion of the blower fan, In addition, there is a gap through which air can flow and communicates with the air conditioning target space in the vicinity of the air conditioning target space side opening of the guide nozzle.

  As described above, according to the present invention, between the air outlet main body inner surface and the guide nozzle, a gap is provided to communicate with the air inlet portion of the blower fan and the air conditioning target space, and the conditioned air is blown from the guide nozzle. Then, with the generation of suction force due to the operation of the blower fan, the ambient air around the outlet in the air-conditioning target space is sucked into the outlet main body and taken into the blower fan, so that the air in the air-conditioning target space is reduced. In addition to being able to blow the part after it has been mixed with the conditioned air in advance, more air than the conditioned air supplied from the duct and flowing into the blower fan can be blown out from the guide nozzle to the air conditioning target space. It is possible to more efficiently execute local air conditioning to a desired location to be blown from the nozzle.

  The air flow guide portions 41 and 42 are isolated between the guide tube portion 23 and the inner surface of the air outlet main body 10, but communicate with the air inlet portions of the blower fans 31 and 32 and are guided. A gap through which air can be circulated is formed in the portion between the outer side of the decorative plate 12 and the frame portion 10c in the vicinity of the opening portion on the indoor space side of the nozzles 21 and 22.

  The blower fans 31 and 32 are disposed at predetermined positions closer to the duct 81 than the guide nozzles 21 and 22 in the outlet main body 10. More specifically, the opening on the conditioned air inflow side in each guide cylinder portion 23. It is a structure that is attached to the part, operates based on control from the outside, and allows the delivery air to flow only into the air passages of the guide nozzles 21 and 22 through the guide tube portion 23.

  The blower fans 31 and 32 have a mechanism that can be switched between an operating state and a non-operating state by the control unit 60 based on a remote operation using a user operation terminal 65. The configuration of the blower fans 31 and 32 is the same as that of a known axial fan, and detailed description thereof is omitted.

  In the guide tube portion 23 between the blower fans 31 and 32 and the guide nozzles 21 and 22, the swirl velocity component of the airflow generated by the blower fans 31 and 32 is attenuated to increase the straightness of the airflow. A known plate-like rectifying portion 33 is disposed across the inside of the guide tube portion 23.

  The air flow guide portions 41 and 42 are a plurality of substantially plate-like guide bodies 43 arranged so as to be arranged in a truncated conical shape of a truncated pyramid, and further arranged in a plurality at a predetermined interval. It is. The airflow guide portions 41 and 42 have the guide body inclined surface at the outermost peripheral portion opposed to the inner side surface of the outer cone portion 10b of the outlet body 10, and any of the guide bodies 43 is expanded toward the indoor space side. As an arrangement form, it is configured to be disposed at positions closer to the indoor space on both sides sandwiching the two guide nozzles 21 and 22 at the center in the opening 11 of the outlet body 10.

A plurality of guide bodies 43 are fixed to the rod-shaped support body 45 and arranged in parallel with each other between the guide bodies 43 as an air flow guide direction. The structure of each airflow guide portion 41, 42 combined with such a guide body 43 is equivalent to a structure obtained by cutting and dividing a known middle cone portion used for a conventional multi-layer cone type outlet, and detailed description thereof is omitted. To do.

  In addition, in the airflow guide parts 41 and 42, it is set as the structure which uses two sets of large and small what combined the guide body 43 in the expanded shape, but it is not restricted to this, Only one set of guide bodies is provided, or three sets It can also be provided as described above.

  In addition, the two air flow guide portions 41 and 42 are set as the same size across the decorative plate 12 portion with the guide nozzles 21 and 22, respectively, but the size setting is not limited to this, The size may be different for each airflow guide.

  The shielding portion 50 is disposed at least between the connection portion with the duct and the conditioned air inflow portion of the blower fan inside the air outlet body 10, and divides the opening of the air outlet body 10 to conditioned air. Is divided into a part toward the blower fans 31 and 32 and another part toward the airflow guides 41 and 42.

  Specifically, the shielding portion 50 is formed in a substantially box shape, and surrounds and arranges the two guide tube portions 23 to which the guide nozzles 21 and 22 and the blower fans 31 and 32 are attached in the outlet body 10. It is a configuration to be provided.

  The shielding part 50 is formed of a substantially rectangular box-shaped body made of a thin plate, and a plurality of rectangular holes 51 are arranged in a line in the long side direction of the upper surface in a plane on the flat upper surface portion and arranged at a predetermined pitch. The lower side is in an open state, and the upper surface side is positioned in the vicinity of the neck portion 10a so as to be disposed inside the outlet body 10.

  A through hole 52 is provided in a side surface portion of the shielding portion 50 near the air flow guide portions 41 and 42, and conditioned air passes through the hole 52 from the side end portion side of the opening portion 11 of the air outlet main body 10 and blows the fan. 31 and 32 can be introduced.

  And this shielding part 50 is a plate shape in which a plurality of holes are perforated at the upper part located between the connection part of the blower outlet body 10 with the duct 81 and the conditioned air inflow part of the blower fans 31 and 32. An opening / closing structure in which two bodies are superposed and slidably arranged with each other is provided. More specifically, a substantially plate-like slide plate 55 slidable along the upper surface portion is provided above the plate-like upper surface portion of the shielding portion 50 so as to correspond to each of the blower fans 31 and 32. It is a configuration to be provided. The actuator 14 that moves the slide plate 55 relative to the upper surface of the shielding portion to change the position is disposed on the side of the shielding portion 50.

  The slide plate 55 is formed as a substantially rectangular thin plate having a size slightly smaller than half of the upper surface portion of the shielding portion 50, and has a plurality of holes 56 having substantially the same shape and arrangement as the holes 51 on the upper surface portion of the shielding portion 50. It is provided and is configured to be slidable in the surface long side direction along the upper surface portion of the shielding portion 50.

  The actuator 14 is disposed on the side of the shielding part 50 and has a structure in which a movable part is connected to an end part on the slide plate 55 side. The slide plate 55 is fully opened by overlapping the hole 51 on the shielding part 50 side. This is a mechanism for changing the position between the state position and the position where each hole 56 is displaced in the direction in which a plurality of holes 56 are arranged so as not to overlap the hole 51.

  By adjusting the position of the slide plate 55 by the actuator 14, the holes 51 and 56 are not fully overlapped (see FIG. 5A), and the holes 51 and 56 are all overlapped (FIG. 5B). ))) Can be switched. The actuator 14 is controlled to operate in response to switching between the operating state and the non-operating state of the blowing fans 31 and 32. When the blowing fans 31 and 32 are in the operating state, the actuator 14 is moved to the slide plate. 55 is moved to a fully open state where the holes 51 and 56 are all overlapped, and conversely, when the blower fans 31 and 32 are deactivated, the actuator 14 moves the slide plate 55 so that the holes 51 and 56 are completely overlapped. It is a mechanism that makes it a fully closed state. Note that the movable mechanism itself of the actuator 14 is well known, and detailed description thereof is omitted.

  In this manner, on the upper surface portion of the shielding portion 50, the slide plate 55 is moved relative to the upper surface portion by driving by the actuator 14, the holes overlap each other, and the conditioned air can pass through the holes (FIG. 5B )) And the closed state (see FIG. 5A) where the holes do not overlap each other and conditioned air cannot pass through the holes.

  Thus, in the open state of the upper surface portion of the shielding portion 50, the conditioned air passes through the holes and flows into the inflow side openings of the guide nozzles 21 and 22 via the blowing fans 31 and 32 that operate simultaneously. , 22 is blown out. In the closed state of the upper surface portion of the shielding portion 50, the conditioned air that has reached the upper surface portion does not pass through the closed hole and moves sideways along the upper surface portion to reach the air flow guide portions 41 and 42. The airflow is guided from the airflow guides 41 and 42. In the closed state of the upper surface portion of the shielding portion 50, the blower fans 31 and 32 are also inactive, and most of the conditioned air that has flowed into the opening 11 of the outlet body from the duct side is caused by the shielding portion 50 to be the airflow guide portion. It is a mechanism guided to the 41 and 42 side.

  Such switching of the blowing state is realized with a simple structure in which the upper surface portion of the shielding portion 50 and the slide plate 55 are slid and overlapped, and the switching reliability can be improved. In addition, the portion where the two plate-like bodies in the shielding portion 50 are overlapped can reduce the size in the thickness direction, and the outlet body 10 that accommodates the portion is also compact in the vertical direction parallel to the thickness direction. Structure.

  The control unit 60 is electrically connected to the blower fans 31 and 32 and the actuator 14 in the air outlet body, and receives an operation information signal from an operation terminal 65 such as a user's remote control in the indoor space. , And controls the operations of the blower fans 31 and 32 and the actuator 14 based on the signal.

  The control unit 60 receives a signal transmitted from the operation terminal 65 when the user performs a local blowing instruction operation on the operation terminal 65 while the blower fans 31 and 32 are inactive. Then, the blower fans 31 and 32 are actuated to send conditioned air to the guide nozzle side, and the actuator 14 is actuated to slide the slide plate 55 so that the upper surface portion of the shielding portion 50 is in an open state. The conditioned air is smoothly blown out from the guide nozzles 21 and 22 so that the conditioned air is directed toward the blower fans 31 and 32 through the shortest path, so that the conditioned air flow locally reaches a desired area of the living area. It will cause a condition.

  Further, the control unit 60 is a signal transmitted from the operation terminal 65 when the user performs an instruction operation to stop the local blowing on the operation terminal 65 in a state where the blower fans 31 and 32 are operated. In response, the operation of the blower fans 31 and 32 is stopped, the actuator 14 is operated, the slide plate 55 is slid in the opposite direction to the above, and the upper surface portion of the shielding portion 50 is closed, so that the harmony from the duct 81 is achieved. The air is made easier to flow toward the air flow guide portions 41 and 42, and the conditioned air is blown out from the air flow guide portions 41 and 42 so as to be returned to a state of being widely diffused in the indoor space.

  For communication between the control unit 60 and the operation terminal 65, wireless communication represented by standard systems such as IEEE 802.11 series and IEEE 802.15 series can be used in addition to a general infrared type or radio wave type using a remote controller or the like.

  Moreover, the control part 60 is not restricted to what specialized in control of the fans 31 and 32 for ventilation, or the actuator 14, For example, control parts, such as illumination arrange | positioned in the blower outlet 1 vicinity in the case of a grid type system ceiling, for example Also, it can be configured to also serve as a control unit for turning on / off the illumination or changing the brightness according to an instruction from the user via the operation terminal.

  Next, the airflow guiding state in the air outlet device based on the above configuration will be described. As a premise, as a blowing state of the outlet device, a mode in which the blowing fans 31 and 32 are in an operating state and the blowing is locally performed from the guide nozzles 21 and 22 and a blowing fan is in a non-operating state. It is possible to select any one of the modes for diffusing and blowing from 41 and 42, and in a normal situation, the mode is mainly for blowing from the airflow guides 41 and 42, and the guidance is provided by remote operation by the user's operation terminal 65. It is assumed that a mode for locally blowing from the nozzles 21 and 22 is selected.

  When the user does not perform any particular operation, the blowout is performed mainly in the mode of diffusing and blowing from the airflow guide portions 41 and 42, and the slide plate 55 is in a position where the hole is closed (FIG. 5A )), And the blower fans 31 and 32 are in an inoperative state.

  The conditioned air supplied from the duct 81 smoothly proceeds to the opening 11 of the air outlet main body 10 through the neck portion 10a of the air outlet device 1 and travels to each position of the opening 11 including the shielding part 50. In this state, since the hole of the shielding part 50 is closed, the conditioned air that has advanced from the duct 81 to the opening part 11 of the outlet body 10 is more likely to travel to the airflow guide part side compared to the blower fan side. Yes. In particular, the conditioned air that has reached the upper surface of the shielding part travels laterally on the upper surface of the shielding part and reaches the airflow guide parts 41 and 42 closer to the indoor space. In this way, the conditioned air can be reliably directed to the airflow guide portions 41 and 42.

  In this case, the air flow of the conditioned air is blown horizontally from the air flow guides 41 and 42 to the indoor space (see FIG. 6A), and the conditioned air is reliably diffused in a wide area of the indoor space. Harmony is achieved, and the temperature of the indoor space can be adjusted uniformly.

  In addition, in the opening part 11 of the blower outlet main body 10, a part of the conditioned air flows into the inner region of the shielding part 50 where the blower fans 31 and 32 are located through the holes 52 near the airflow guide parts 41 and 42 of the shielding part 50. Therefore, a part of the conditioned air is blown out from the guide nozzles 21 and 22 through the blower fans 31 and 32 and the guide tube portion 23. However, since the amount of air blown out is small, a draft or the like is given to the user in the living area. There is no feeling.

On the other hand, when a mode in which the user blows locally from the guide nozzle is selected by the operation of the operation terminal 65, the control unit 60 operates the actuator 14 based on this and the slide plate 55 is moved by the actuator 14. The holes 51 on the upper surface of the shielding portion are moved from the closed state to the open state (see FIG. 5B), and the blower fans 31 and 32 are also moved from the non-operating state to the operating state.
As described above, the conditioned air supplied from the duct 81 smoothly proceeds to the opening 11 through the neck portion 10 a of the outlet body 10, and travels to each position of the opening 11 including the shielding portion 50.

  In this state, the conditioned air that has advanced from the duct 81 into the air outlet main body is caused to flow into the blower fan through the hole 51 of the shielding portion 50 while maintaining the delivery speed from the duct 81 as much as possible. , 32 is actuated to add the blowing pressure to the conditioned air, and the conditioned air is sent to the guide nozzles 21 and 22 through the guide tube portion 23.

Accordingly, conditioned air is locally blown out from the guide nozzles 21 and 22 located closer to the indoor space toward a specific narrow area of the indoor space where the user exists (see FIG. 6B). Then, the conditioned air is powerfully blown out from the guide nozzles 21 and 22 into the indoor space, so that the conditioned air can reach the position of the user in the living area, and the coolness or warmth is prevented from the airflow hitting the user's body. It is possible to obtain a powerful sensation temperature adjustment state in which the user can be directly experienced, for example, to quickly shift the user to a comfortable state. However, since conditioned air is blown locally toward a narrow area of the indoor space, the influence on the entire indoor space can be suppressed.
In this case, since a part of the conditioned air is directed to the airflow guide portions 41 and 42 at the opening 11 of the outlet body 10, the airflow is also slightly blown out from the airflow guide portions 41 and 42.

  In addition, a suction force is generated in the inflow side space of the blower fans 31 and 32 by the operation of the blower fans 31 and 32, and specifically, a shield is provided between the inner surface of the blowout outlet body 10 and the guide nozzles 21 and 22. When there is a gap between the inner surface of the portion 50 and the outer surface of the guide tube portion 23, the suction fans 31 and 32 are operated to blow conditioned air from the guide nozzles 21 and 22, and the suction force is drawn through the gap. Acting on the indoor space side, a part of the ambient air around the air outlet in the indoor space is sucked into the air outlet main body 10 from the opening portion on the side of the decorative plate 12 and the air inlets of the blower fans 31 and 32 through the gaps It can reach the part and be taken into the fan for blowing.

  As a result, a part of the air in the indoor space is mixed with the conditioned air in advance and then blown out, and more air than the conditioned air supplied from the duct 81 and flowing into the blower fans 31 and 32 is supplied from the guide nozzles 21 and 22. The air can be blown into the indoor space, and the local air conditioning to a desired location to be blown from the guide nozzle can be more efficiently performed.

  Since the guide nozzles 21 and 22 are rotatably arranged with respect to the outlet body 10, the guide nozzles 21 and 22 are adjusted with respect to the outlet body 10 to adjust the opening of the opening facing the indoor space. The direction can be changed to change the blowing direction of the conditioned air. The user can arbitrarily adjust the direction in which the conditioned air is blown within a range in which the opening portion of the guide nozzle on the indoor space side can be exposed from the opening hole 12a of the decorative plate 12 (see FIG. 6B). The blowing direction can be appropriately set according to the situation of the user in the living area, and air conditioning can be performed efficiently.

  When the user cancels the mode of locally blowing from the guide nozzle by operating the operation terminal 65, it will return to the normal mode of diffusing and blowing from the airflow guide portions 41 and 42, The slide plate 55 is moved by the actuator 14 so that the hole is changed from the open state to the closed state (see FIG. 5A), and the blower fans 31 and 32 are changed from the operating state to the non-operating state.

  In this state, the conditioned air that has advanced from the duct 81 to the opening 11 of the outlet main body 10 proceeds from the blower fan side to the airflow guide portions 41 and 42 by closing the hole of the shielding portion 50 as described above. It becomes easy to perform, and the airflow of conditioned air is blown out to the wide range from the airflow guide parts 41 and 42, and air conditioning can be performed by diffusing conditioned air reliably in the wide area | region of indoor space.

  Even when the upper surface of the shielding unit 50 is closed and the blowing fans 31 and 32 are inactive and the local blowing from the guide nozzles 21 and 22 is not actively performed, the amount of air supplied to the air outlet is maintained. It does not affect the entire air conditioning system including the air outlet.

  In addition, in the control unit, the blowing from the guide nozzle is performed or not, or only the switching between the fully open and fully closed state is performed, but in the situation where the blowing is performed locally, by the rotation speed control of the blower fan It is also possible to adjust the air flow rate and the opening degree by sliding the slide plate to adjust the air volume of the conditioned air blown from the guide nozzle to change the degree of arrival near the user.

  As described above, in the air outlet device according to the present embodiment, the air flow guide portions 41 and 42 that guide the air flow of the conditioned air in a plurality of directions are arranged in the opening portion 11 of the rectangular opening cross section in the air outlet body 10. In addition, the local blowing guide nozzles 21 and 22 and the blower fans 31 and 32 that are independent of the airflow guides 41 and 42 are arranged, and the blower fans 31 and 32 act as desired from the guide nozzles 21 and 22. The state in which the conditioned air can be locally blown to the position of the air, and the conditioned air is guided mainly by the air flow guide portions 41 and 42 in accordance with the non-operation of the blower fans 31 and 32, and the air conditioning target room Since it is possible to select a state in which the air flow of conditioned air is widely diffused in the space, the air flow of the conditioned air is blown out from the air flow guide portions 41 and 42 of the opening 11 to a wide range, and is adjusted in a wide area of the indoor space. In addition to being able to harmonize air by reliably diffusing air, the guide nozzles 21 and 22 are blown locally to a specific narrow area where the user exists as necessary, while suppressing the influence on the entire space. Air conditioning can be performed efficiently with a single outlet, for example, the temperature of the user can be improved by locally adjusting the temperature of the user in the living area, thereby reducing the cost of air conditioning. Further, even when the blower fans 31 and 32 are not operated and the local blowout is not actively performed from the guide nozzles 21 and 22, the amount of air supplied to the blowout port can be maintained, and the entire air conditioning system including the blowout port. Will not be affected.

  In addition, in the blower outlet device which concerns on the said embodiment, the control part 60 corresponding to the blower outlet apparatus 1 is used, This control part 60 receives the signal from the operation terminal 65 by the side of a user, and is for ventilation. It is configured to control the operation of the fans 31, 32 and the actuator 14, but in addition to this, from a communication terminal such as a mobile phone or a smartphone of a user who is present in the room, or a computer used by the user, The communication control unit includes a communication control unit that receives operation information signals on behalf of a telephone line network and a network, and an operation control unit that performs operation control corresponding to each of a plurality of indoor outlet devices. Of the operation control units, an operation command signal can be sent to the operation control unit of the outlet device corresponding to the user operated from the communication terminal. Except, even from a general mobile communication terminal or computer, the user local blowing start of at outlet allows instruction operation termination, is caused to further improve convenience.

  In this case, first, the communication control unit receives a signal of operation information transmitted from a communication terminal such as a mobile phone of a predetermined user in the living area of the indoor space, and the communication control unit transmits the signal of the operation information. By recognizing the original communication terminal and the user, the position of the outlet device to be operated is determined at a predetermined indoor location associated with the user in advance. Then, the communication control unit sends an operation command signal to the operation control unit corresponding to the outlet device at the operation target position, and the operation control unit that receives the operation command performs operation control of the blower fan and the actuator. Become.

  In the air outlet device according to the embodiment, the slide plate is slid using an actuator that is controlled by the control unit, and the open / close state of the upper surface of the shielding unit is switched in accordance with the operation of the blower fan. Although it is configured so that it can smoothly flow into the blower fan that operates air at the shortest distance, it is not limited to this, and an actuator is not used, and it opens and closes between the air inflow side of the blower fan and the outlet body neck When the blower fan is not in operation using a biasing means, etc., the closed body is kept closed so that the conditioned air does not go straight to the blower fan side. Due to this, the state where the balance between the pressure and the urging force is lost collapses and the closing body moves, thereby opening the state, and during the operation of the blower fan, the open state is based on the changed pressure. Can be a lifting Configurations, cost containment can be achieved an actuator as required.

  Moreover, in the blower outlet apparatus which concerns on the said embodiment, although the structure of the upstream part of the duct 81 connected to the blower outlet apparatus 1 is not specifically limited, In addition, the duct predetermined | prescribed as the upstream of a blower outlet apparatus is predetermined. A variable air volume adjusting unit (VAV) is provided at the location, and the air volume is adjusted by the variable air volume adjusting unit (VAV) according to the temperature of the indoor space measured by a temperature sensor provided on a wall or the like of the indoor space. It can be set as the structure which adjusts. In this case, furthermore, a temperature sensor is attached to the operation terminal 65, the temperature at the position where the user in the living area is active is measured, and the obtained temperature information is transmitted to the control unit of the variable air volume adjustment unit. The air volume control of the variable air volume adjustment unit may be executed based on the information, and the temperature adjustment suitable for the user's feeling can be performed by the control based on the temperature at a position closer to the user, thereby improving the comfort of the indoor space. Can be improved.

  Then, the temperature information obtained by the temperature sensor of the operation terminal may be transmitted to a control unit such as a blower fan of the blowout device, and the temperature in the vicinity of the user, for example, is the target temperature. If the air pressure exceeds a large value, the air flow of the conditioned air that locally reaches the living area is weakened by reducing the rotational speed of the blower fan or moving the slide plate to lower the opening ratio of the upper surface of the shielding part. Such control may be executed.

(Second embodiment of the present invention)
In the blower outlet device according to the embodiment, the two guide nozzles 21 and 22 and the two air flow guide parts 41 and 42 sandwiching the two guide nozzles 21 and 22 are arranged in the rectangular opening 11 of the blower outlet body 10. However, the present invention is not limited thereto, and as a second embodiment, as shown in FIGS. 8 to 12, a blower outlet body 15 that is a substantially box-like body surrounding the opening 16 having a rectangular opening cross section is disposed. Four guide nozzles 25, 26, 27, and 28 are provided at the central portion of the opening 16 in the main body 15, and four sets of air flow guide portions 45, 46, 47, and 48 are disposed around the guide nozzles. It can also be configured.

  In this case, the air outlet body 15 of the air outlet device 2 can be fixed to the ceiling 80 by being attached to the support frame 82 of the grid type system ceiling in the ceiling 80 via the attachment plate 83. In the state of being arranged on the ceiling 80 in this manner, as in the first embodiment, the air flow guide portions 45, 46, 47, and 48 on the outer peripheral portion are conditioned air blown horizontally and diffused widely in the indoor space, If necessary, the air conditioner can be locally conditioned by allowing the air flow of the conditioned air to reach any position in the living area from the guide nozzles 25, 26, 27, 28 that can adjust the blowing direction.

  The outlet body 15 is formed as a substantially box-like body as in the first embodiment except that the outlet body 15 has a shape that surrounds the opening 16 having a rectangular opening cross section. The outer cone portion 15b having an expanding shape toward the indoor space side is formed in the portion, and the frame portion 15c protruding outward from the lower end portion of the outer cone portion 15b with respect to the opening portion 16 is formed. Is.

  And the blower outlet main body 15 is connected with the duct 81 by the cylindrical neck part 15a connected with an upper surface, receives supply of conditioned air from the duct 81 through this neck part 15a, and is an opening part like the said 1st Embodiment. The conditioned air introduced into 16 is blown out into the indoor space through guidance by the guide nozzles 25, 26, 27, 28 and the airflow guide portions 45, 46, 47, 48.

  The guide nozzles 25, 26, 27, and 28 are arranged in the indoor space for each nozzle in an intermediate portion surrounded by the airflow guide portions 45, 46, 47, 48 on the indoor space side of the opening 16 of the outlet body 15. A decorative plate 17 having an opening 17a to be exposed is disposed to prevent leakage of conditioned air from other than the guide nozzles and the airflow guide.

  The guide nozzles 25, 26, 27, and 28 are formed as a substantially cylindrical body having a spherical outer peripheral portion, as in the first embodiment, and the opening 16 of the outlet body 15 via the guide cylinder portion 23. The center portion is supported so that the orientation can be adjusted, and detailed description thereof is omitted. And the fan 35, 36, 37, 38 for ventilation is arrange | positioned like the said 1st Embodiment in the predetermined position in the blower outlet main body 10 nearer the duct 81 than these guide nozzles 25, 26, 27, 28. Is done.

  These blower fans 35, 36, 37, and 38 are respectively attached to opening portions on the conditioned air inflow side of the guide cylinder portion 23, and are operated by the control unit 60 based on a remote operation using a user operation terminal 65. It is the same as in the first embodiment in that the state and the non-operating state are switched, and the delivery air is allowed to flow into the air passages of the guide nozzles 25, 26, 27, and 28 through the guide tube portion 23.

  Further, a substantially box-shaped shielding part 53 is disposed in the outlet body 10 so as to surround the blower fans 35, 36, 37, 38, the guide cylinder part 23, and the guide nozzles 25, 26, 27, 28. This is also the same as in the first embodiment.

  The airflow guide portions 45, 46, 47, and 48 are plate-like portions on the outer periphery of the decorative plate 17 that face the outer cone portion 15 b of the outer peripheral portion of the air outlet body, and the four guide nozzles 25 in the center portion of the opening portion 16. , 26, 27, and 28, the conditioned air travels along the back surface of the plate-like portion, and guides the conditioned air together with the outer outer cone portion 15 b to be blown out in the horizontal direction with respect to the indoor space. Will be.

  As in the first embodiment, the shielding portion 53 has a plurality of holes 59 made of a plate-like body that can slide along the upper surface of the plate-like upper surface portion in which a plurality of holes 54 are formed. Four sets of slide plates 58 are provided corresponding to each guide nozzle. By adjusting the position of the slide plate 58, the fully open state in which the holes 54 and 59 overlap and the fully closed state in which the holes 54 and 59 do not overlap with each other are provided. The state can be switched. On the upper side of the shielding portion 53, an actuator 19 that slides the slide plate 58 with respect to the shielding portion 53 to change the position is disposed for each slide plate.

  In addition, the guide nozzles 25, 26, 27, and 28 in the central portion of the opening 16 can be used by selectively attaching 1 to 4 guide nozzles depending on the use situation, and 1 to 3 guide nozzles are used. Instead, a decorative board without an opening hole is attached to a part where the nozzle is not used. And even when such an alternative decorative board is used, the guide body 49 which makes the back surface of the outer peripheral part which opposes the outer cone part 15b of a blower outlet main body outer periphery part with the outer cone part 15b similarly to the normal decorative board 17 It functions as an airflow guide that guides conditioned air.

  Next, the airflow guiding state in the outlet device according to the present embodiment will be described. As in the first embodiment, the blowing state includes a mode in which blowing fans 35, 36, 37, and 38 are activated and a blowing is locally performed from the guide nozzles 25, 26, 27, and 28, and a blowing fan 35. , 36, 37, and 38 can be selected as a non-operating state, and any of the modes of diffusing and blowing out from the airflow guides 45, 46, 47, 48 can be selected. In normal circumstances, the airflow guide 45 is mainly used. , 46, 47, and 48, and a mode for locally blowing from the guide nozzles 25, 26, 27, and 28 is selected by a remote operation by the user's operation terminal 65.

  When the user does not perform any operation, in the mode in which the air is mainly diffused and blown out from the airflow guides 45, 46, 47, 48, the slide plate 58 is in a closed state (see FIG. 12A). In position, the blower fans 35, 36, 37, 38 are inactive. In this case, the conditioned air travels from the duct 81 to the opening 16 of the outlet body 15 through the neck portion 15a, and the hole 54 of the shielding portion 53 is closed. 46, 47, 48, the air flow of the conditioned air is blown horizontally from the air flow guides 45, 46, 47, 48, and the conditioned air is diffused in a wide range of the indoor space.

  On the other hand, when the user selects a mode in which the user blows locally from the guide nozzle by operating the operation terminal 65, based on this, the control unit 60 operates the actuator 19, and the actuator 19 moves the slide plate 58. As a result, the hole 54 on the upper surface of the shielding portion changes from the closed state to the open state (see FIG. 12B), and the blower fans 35, 36, 37, and 38 change from the non-operating state to the operating state.

  The conditioned air supplied from the duct 81 proceeds to the opening 16 of the outlet body 15 and travels to each position of the opening 16 including the shielding part 53. In this state, the conditioned air that has advanced from the duct 81 into the outlet body flows into the blower fan through the hole 54 of the shielding portion 53 while maintaining the delivery speed from the duct 81 as much as possible. The blast pressure is added by the operation of 36, 37, 38, and the air is sent to the guide nozzles 25, 26, 27, 28.

  Thus, the conditioned air is blown locally from the guide nozzles 25, 26, 27, and 28 toward a specific narrow area of the indoor space where the user exists, and the conditioned air reaches the position of the user in the living area. Thus, it is possible to obtain a powerful sensory temperature adjustment state that promptly shifts the user to a comfortable state.

  When the user releases the mode of locally blowing from the guide nozzle by operating the operation terminal 65, the mode returns to the normal mode of diffusing and blowing from the airflow guide unit. The slide plate 58 is moved to change the hole from the open state to the closed state, and the blower fans 35, 36, 37, and 38 are changed from the operating state to the non-operating state. In this state, the conditioned air that has advanced from the duct 81 to the opening 16 of the outlet body 15 proceeds toward the airflow guides 45, 46, 47, and 48 because the hole 54 of the shielding part 53 is closed as described above. The air flow of conditioned air is blown out from the air flow guide portions 45, 46, 47, and 48 in a wide range.

  As described above, the air outlet device according to the present embodiment has four air flow guide portions 45, 46, 47, and 48 for diffusing the air flow of conditioned air and blowing it as the blowout portion, and four guide nozzles for local blowout. 25, 26, 27, and 28, and the state where local air can be blown out from the guide nozzles 25, 26, 27, and 28 to a desired position, and the air flow guides 45, 46, 47, and 48 mainly. Since the air can be guided and the airflow of the conditioned air can be widely diffused from the outlet position to the indoor space, the airflow guides 45, 46, 47, and 48 In addition to ensuring that the conditioned air is diffused over a wide range of areas, the conditioned air can be distributed from four guide nozzles 25, 26, 27, and 28 to areas where there are a maximum of four users as required. Local blowout It is performed, by performing the temperature control for a plurality of users located efficiently occupied zone in one of the air outlet, so that the attained quickly comfort improvement of the user.

  In the air outlet apparatus according to each of the above embodiments, once the control unit 60 switches the blower fan to the activated state based on the operation of the user operation terminal 65, the user newly opens the operation terminal 65. The controller 60 is configured to maintain the operating state of the blower fan until it is operated to stop the local blowing state. However, the configuration is not limited to this, and a predetermined portion facing the indoor space of the air outlet device and / or for operation When a human sensor is provided in a part of the terminal 65 and the absence of a person in a predetermined area of the living area, which is a target of conditioned air blowing from the guide nozzle, is identified by the human sensor, the control unit deactivates the blower fan In this state, the sliding plate is slid together to close the upper surface of the shielding portion, and the local blowing from the guide nozzle can be stopped.

  In this case, when the user leaves the target area where the conditioned air flow is made to reach for a predetermined time or more while the blowing state is the mode in which the blowing is locally performed from the guide nozzle, the conditioned air is quickly transferred from the air flow guide unit to the indoor space. By shifting to a widely diffused blowout state, the conditioned air that was about to be blown locally to some areas can be effectively used for air conditioning for the entire indoor space, and the air efficiently into the indoor space. Harmony can be achieved.

  In addition to such a human sensor, a temperature sensor is provided in a part of the operation terminal 65, and the temperature in a predetermined area of the living area, which is a target of conditioned air blowing from the guide nozzle, is measured by the temperature sensor. When the temperature is significantly different from the target temperature for air conditioning in the entire room, the control unit can be configured to control each part so as to stop the local blowing from the guide nozzle, and the air conditioning is stopped for a while. In an inadequate air-conditioning situation where the temperature of the indoor space is not yet uniform, such as immediately after starting the air-conditioning for the indoor space, the air conditioning for the entire indoor space is given priority in as short a time as possible. The indoor space can be shifted to a generally comfortable temperature state.

  Further, in the air outlet device according to each of the above embodiments, in a state where the conditioned air is mainly diffused from the air flow guide portion and blown out, the air flow guide portions provided at the ends of the opening portions of the air outlet body are conditioned air. However, this is not limited to this, and another air flow guide member can be used together with the air flow guide unit. In combination, the air flow of the conditioned air can be blown obliquely downward from the air flow guide unit, adopting a more preferable diffusion blowing state corresponding to the situation of the air conditioning target space, air conditioning Can be executed efficiently.

  In the outlet device according to the embodiment, the guide nozzle and the airflow guide are exposed in the indoor space. However, the present invention is not limited thereto, and the indoor space side of the guide nozzle and / or the airflow guide is used. In addition, it is a substantially plate-like body having a large number of holes of sufficient size that allow conditioned air to pass without resistance in a regular arrangement that provides a predetermined opening ratio, and covers the guide nozzle and / or the airflow guide section. It can also be set as the structure which arrange | positions the decorative grille to hide. In this case, the decorative grille makes it difficult to see the inner guide nozzle and the airflow guide part directly from the indoor space side while minimizing the influence of the conditioned air flow guided by the guide nozzle and the airflow guide part. Therefore, it is possible to suppress a sense of discomfort in the appearance of the exposed part of the air outlet, improve the unity of the ceiling design, and improve the aesthetics.
